Cartilage is a type of connective tissue that is found throughout the body, from the nose to the ends of our fingers. Cartilage can be rigid and stiff or soft and flexible depending on its location in the body.
This article will examine cartilage definitions, structure, functions, and characteristics to help you better understand how it works! However, should you chose to skip this guide due to reasons such as a busy schedule, our professional writers for hire are ready to cover you by doing that assignment for you. Just place an order and leave it to us.
The cartilage is a dense, sponge-like matrix of collagen fibers located throughout the body. Cartilage is formed of tiny cells called chondrocytes and is surrounded by a thin, transparent membrane. It has an appearance similar to that of the brain and the spinal cord.
Cartilage is a type of connective tissue that gives strength and elasticity to joint bones and protects the bones. It is found everywhere in the body, and its characteristics depend on the specific location.
Chondroitin sulfate is a major component of cartilage which is a glycosaminoglycan. It’s an essential part that composes the matrix of collagen fibers and provides the cartilage with its elasticity and protects the bone.
An extracellular matrix binds chondrocytes together and allows the cartilage to be flexible and elastic. Chondroblasts are the other specialized cells of the cartilage tissue found in the cartilage matrix. They are responsible for producing new cells and for rebuilding damaged tissue.

- The Extracellular matrix
Fibroblasts are part of all connective tissues, and they produce the collagen fibers that make up most of the cartilage. They are responsible for producing collagen protein and giving cartilage its elasticity.
Chondroblasts are the cells responsible for replenishing and maintaining cartilage. Chondrocytes are specialized types of fibroblasts that produce chondroitin sulfate.
The extracellular matrix, which makes up the majority of the cartilage, is a fluid-like, healthy environment. It provides the joint with its elasticity and strength while also creating a protective cushion for the bone.
The matrix comprises collagen, fibronectin, lipids, proteoglycans, and the cells; these make up bone cartilage. It supports the cells that produce it while providing a medium for the exchange of nutrients and waste products between the cells and their surrounding environment.
The caoutchouc is a type of cartilage that has the appearance and elasticity of rubber. It’s found in areas like the ear, nose, and larynx.
The cartilage that is located in the eardrum, called the tympanic membrane, is an example of elastic cartilage. It is sensitive to heat and cold because the extracellular matrix does not have a high tolerance for temperature changes. This explains why the cartilage is damaged when exposed to extreme heat or cold.
There are three different types of cartilage:
- Elastic Cartilage
- Hyaline Cartilage
A) Elastic Cartilage
Elastic cartilage is found in the larynx, trachea, and bronchial tubes, where it provides elasticity. It is a connective tissue that consists of collagen and elastin fibers that allow for flexibility.
Elastic cartilage is the type of cartilage most often found in the body and provides a free-flowing, flexible environment for bones. This connective tissue is highly flexible hence withstands bending pressure.
This type of cartilage provides elasticity to the bones and protects them from being crushed. It also helps to maintain the shape of the external ear. In the human body, elastic cartilage is also found in the epiglottis, providing elasticity in the trachea.
Fibrocartilage is a dense connective tissue with a higher concentration of collagen fibers than hyaline cartilage and is found in the ear, nose, and ribs.
The fibrocartilaginous type of cartilage is the most resistant to pressure, and it has a heavy collagen fiber matrix. It also protects from injury, shock absorption, and stability for the joint.
Of the three types of cartilage, fibrocartilage is the only one that contains both types I and Type II cartilage. It is found in the menisci, the discs between the joints, and ligaments.
C) Hyaline Cartilage
Hyaline cartilage is located in places that are exposed to a lot of pressure and stress, such as the joints, rib cage, and larynx.
The hyaline cartilage is also found in the nose and ears; it is soft, spongy, and flexible. It is also found in the pubic symphysis, where it helps to provide elasticity.
This type of cartilage contains a high concentration of collagen fibers which provide flexibility. It is also very light because of the high water content, making it more elastic and less dense than fibrocartilage.
The elastic cartilage hyaline also contains a type of proteoglycan, chondroitin sulfate. This is the most common type of cartilage in humans. It provides flexibility and elasticity while also being incredibly lightweight.
The bones of an embryo form as hyaline cartilage then later develop into bones. This fact makes hyaline very crucial in fetal development.
The different types of cartilage have both similarities and differences in structure, functions, and locations:
- Both the hyaline cartilage and elastic cartilage are made of type I collagen fibers. They also have a thicker extracellular matrix than fibrocartilage, and they have high water content.
- The three types of cartilage have a similar function: they provide structural support and protection for the body. Also, they have the same kind of cells called chondrocytes.
- The elastic cartilage has more elastin fibers than the hyaline cartilage, which makes it more flexible.
- The elastic cartilage is also connected to muscles and bones by tendons, ligaments, and joint capsules.
- Fibrocartilage is the stiffest among all three types of cartilage because it has a higher concentration of collagen fibers.
- Fibrocartilage is the least elastic among all three types, and it also has less type I collagen than hyaline cartilage.
- The function of the fibrocartilaginous type of cartilage is to provide protection and stability for joints while also protecting them from injury, shock absorption, and providing stiffness.
- The hyaline cartilage is mainly in the nose, ear, pubic symphysis (joint), and larynx. It is also found in the rib cage, joints, nose, ear, and the pubic symphysis (joint). Here, it provides elasticity, protection, and stability.
- The fibrocartilage is found in the meniscus (cartilaginous discs) between the joints and in ligaments. It provides protection, stability, and stiffness to the joint while also providing shock absorption.
- The elastic cartilage is located in the pubic symphysis (joint). It provides stability, protection, and flexibility.
The process of cartilage formation is called chondrification. The two significant factors that affect cartilage formation are:
- Type I collagen fibers provide elasticity and protection to the body.
- Type II collagen fibers provide stability to the joint.
The cartilage is made up of cells called chondrocytes which produce the cartilage’s extracellular matrix.
The matrix contains proteoglycans, glycoprotein, and water which protect the body. The cells also produce more type II collagen fibers that provide stability to the joint.
Another factor is mechanical stress, which causes chondrocytes to produce more proteoglycans and water, making the cartilage stronger, thicker, and stiffer.
During formation, the cartilage cells are in a resting phase before going back into a proliferative stage. The chondrocytes produce type I collagen fibers that provide elasticity and protection to the body.
Cartilage tissue growth depends on the increased size or mass of the cartilage. It does not grow in length or width as it is a connective tissue and lacks joint structures.
The growth of cartilage is caused by the increase of water and proteoglycans in the extracellular matrix. It also involves the addition of hyaluronic acid that provides lubricant for joints.
The cell size also determines how fast cartilage grows. Cells in the growth phase will produce more proteoglycans and water that increase the size of cartilage.

There are many different ways that cartilage can be repaired. Some of the methods include:
RAT is a type of treatment that helps to reduce inflammation and slow the progression of joint damage caused by rheumatoid arthritis.
Cartilage transplant is a treatment that involves replacing the cartilaginous tissue with healthy tissues from other parts of the body.
It is a treatment done before the cartilage has degenerated. It can be either a temporary or permanent method.
This treatment is done after the cartilage has degenerated. It can be either a temporary or permanent method.
It refers to the treatment done if the cartilage has degenerated and cannot restore cartilage.
Induced Osteogenesis is a treatment done if the cartilage has degenerated and it’s not possible to restore the cartilage. It’s done by transplanting bone marrow cells or stem cells and providing them with a milieu that will induce the growth of new cartilage.

Cartilage is a type of connective tissue which provides support to joints. It is mainly of water, collagen fibers, and proteoglycans (proteins containing sugar molecules). In general, cartilage has the following functions and characteristics: it’s rigid but flexible; it cushions surfaces so they don’t touch directly; its cells regenerate faster when damaged or worn away.
There are three main types of cartilage in your body – articular cartilage, intervertebral discs, and costal cartilages—research more about the structure of different types of cartilage to understand how the human body works. | <urn:uuid:7ac21184-e553-4f2b-a0d4-6c8f0b933da5> | CC-MAIN-2024-51 | http://www.tutorsploit.com/biology/cartilage-definitions-functions-structure-and-characteristics/ | 2024-12-04T15:32:24Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066181697.67/warc/CC-MAIN-20241204141508-20241204171508-00200.warc.gz | en | 0.942727 | 2,192 | 4.3125 | 4 |
To understand various reasons for lower neck and back pain, it is necessary to value the normal layout (anatomy) of the cells of this location of the body. Crucial frameworks of the lower back that can be connected to signs in this area consist of the bony lumbar spinal column (vertebrae, singular = vertebra), discs in between the vertebrae, ligaments around the back and also discs, spine and nerves, muscles of the lower back, interior organs of the hips and abdominal area, and the skin covering the back location. Grabbing Pain In Lower Back
The bony lumbar back is developed so that vertebrae “piled” together can provide a movable support structure while likewise shielding the spinal cord from injury. The spinal cord is composed of anxious tissue that extends down the spine from the mind.
Each vertebra has a spinous procedure, a bony prestige behind the spine, which shields the cable’s nervous tissue from impact injury. Backbone additionally have a strong bony “body” (vertebral body) in front of the spinal cord to offer a platform suitable for weight bearing of all cells over the butts. The back vertebrae pile promptly atop the sacrum bone that is located in between the buttocks.
On each side, the sacrum meets the iliac bone of the hips to develop the sacroiliac joints of the buttocks.
What are common reasons of lower neck and back pain?
Typical sources of low neck and back pain ( lumbar backache) include lumbar pressure, nerve inflammation, lumbar radiculopathy, bony infringement, and problems of the bone and joints. Each of these is examined listed below.
Lumbar strain (acute, persistent): A lumbar pressure is a stretch injury to the ligaments, ligaments, and/or muscle mass of the lower back. The stretching incident lead to tiny rips of differing degrees in these cells. Back strain is thought about among one of the most common causes of lower neck and back pain. Grabbing Pain In Lower Back
The injury can happen because of overuse, incorrect use, or injury. Soft-tissue injury is frequently classified as “acute” if it has actually existed for days to weeks. If the strain lasts longer than three months, it is described as “persistent.” Back stress most often occurs in individuals in their 40s, however it can happen at any age. The problem is characterized by local discomfort in the lower back area with start after an event that mechanically worried the back tissues. The intensity of the injury ranges from moderate to serious, relying on the degree of pressure as well as resulting spasm of the muscles of the lower back.
The medical diagnosis of back pressure is based on the history of injury, the place of the pain, as well as exclusion of nerve system injury. Generally, X-ray testing is only useful to omit bone problems.
The treatment of back pressure includes relaxing the back (to avoid reinjury), medications to eliminate pain as well as muscle spasm, local heat applications, massage, as well as ultimate (after the severe episode settles) replacing exercises to reinforce the lower back and also stomach muscles. Grabbing Pain In Lower Back
Initial therapy in the house might include warmth application as well as preventing reinjury as well as hefty training. Prescription medications that are in some cases made use of for intense lower back pain consist of non-steroidal anti-inflammatory medicines, by shot or by mouth, muscle mass depressants,
Extended periods of lack of exercise in bed are no more suggested, as this treatment might really slow recovery. Back adjustment for periods of up to one month has actually been discovered to be helpful in some clients that do not have indications of nerve irritation.
Future injury is prevented by utilizing back-protection strategies throughout tasks and also assistance tools as needed in your home or work.
Muscle Pressure and Tendon Sprain
A lower back strain or pressure can take place unexpectedly, or can create gradually in time from repetitive motions. Grabbing Pain In Lower Back
Strains take place when a muscular tissue is extended too far as well as rips, harming the muscle itself.
Strains occur when over-stretching and tearing influences ligaments, which link the bones together.
For practical functions, it does not matter whether the muscle mass or ligament is damaged, as the symptoms and treatment coincide.
Typical sources of strain and strain include:
- Lifting a heavy things, or turning the spinal column while lifting
- Unexpected activities that position too much stress on the lower back, such as an autumn
- Poor posture over time
- Sports injuries, especially in sports that entail twisting or large forces of effect Grabbing Pain In Lower Back
While strains as well as strains do not seem serious and do not generally cause resilient pain, the acute pain can be quite serious.
Root Causes Of Chronic Lower Neck And Back Pain
Pain is thought about chronic when it lasts for greater than three months as well as exceeds the body’s natural healing process. Chronic pain in the low back frequently entails a disc trouble, a joint problem, and/or an inflamed nerve origin. Typical causes include:
Lumbar herniated disc. The jelly-like facility of a lumbar disc can break through the tough external layer and aggravate a close-by nerve root. The herniated part of the disc has lots of proteins that trigger swelling when they get to a nerve origin, and swelling, as well as nerve compression, trigger nerve root pain. The disc wall is additionally highly supplied by nerve fibers, and a tear through the wall can trigger extreme pain.
Degenerative disc condition. At birth, intervertebral discs contain water and also at their healthiest. As people age over time, discs shed hydration and also wear down. As the disc loses hydration, it can not stand up to pressures too, as well as transfers force to the disc wall that may develop splits as well as trigger pain or weakening that can lead to a herniation. The disc can likewise collapse and also contribute to stenosis. Grabbing Pain In Lower Back
Ways to Manage Lower Pain In The Back in your home
Chill it Grabbing Pain In Lower Back
Ice is best in the initial 24 to 48 hours after an injury since it reduces inflammation. Even though the heat feels excellent because it assists cover up the pain as well as it does aid unwind the muscular tissues, the warm really irritates the inflammatory procedures. After two days, you can switch over to heat if you prefer. Whether you make use of heat or ice– take it off after about 20 minutes to offer your skin a remainder. If pain continues, talk with a doctor.
Maintain doing your daily tasks. Make the beds, most likely to work, walk the pet. When you’re really feeling much better, routine cardio workouts like swimming, biking, as well as strolling can maintain you– and your back– more mobile. Simply don’t overdo it. There’s no requirement to run a marathon when your back is sore.
Once your lower pain in the back has actually receded, you can assist avert future episodes of back pain by working the muscles that support your lower back, consisting of the back extensor muscle mass. They help you keep the appropriate posture and also alignment of your spine. Having solid hip, pelvic, as well as abdominal muscles likewise provides you much more back support. Stay clear of stomach crises, because they can actually put more strain on your back.
Stretch Grabbing Pain In Lower Back
Don’t rest plunged in your desk chair all the time. Get up every 20 minutes or two and extend the various other means. Because a lot of us invest a lot of time bending ahead in our jobs, it’s important to stand up as well as stretch backward throughout the day. Do not neglect to also extend your legs. Some people find relief from their pain in the back by doing a regular stretching regular, like yoga. Grabbing Pain In Lower Back
Exactly how To Strengthen Your Lower Back
1. Vacuuming Grabbing Pain In Lower Back
When it concerns enhancing the lower back, focusing on your transverse abs which are twisted around the midline of your body is among the most effective methods to do it. These muscle mass are really type in sustaining your back as well as lower back. While individuals typically towards crunches for their transverse abdominal muscles, individuals can inadvertently toss out their lower back if their core isn’t solid sufficient.
Exactly how to do it: In a standing position, take a deep breath as well as attract your stubborn belly switch in towards your spine, contracting and involving your abdominal muscles as you do so. Think of if somebody was going to turn up and punch you in the stomach and you desire your intestine to be tough and also able to take it; that’s what it must seem like. Hold it, and also launch gradually. Repeat a few more times.
2. Bridge pose
Working your glutes pulls double-duty for back toughness, too. The gluteus maximus is just one of 3 muscular tissues that wrap into the glutes as well as is actually the strongest and biggest muscle in the whole body. They’re responsible for all our movement, which is why enhancing them actually aids your lower back.
3. Donkey kicks Grabbing Pain In Lower Back
This is another glutes workout step that doubles as a lower-back helper.
How to do it: Get down on your hands and knees, with your hands directly over your shoulders. Raise up your best leg, maintaining your knee at a 90-degree angle, up until your leg is alongside the ground. Slowly lower it back down to the ground. Repeat for 90 seconds, after that switch legs.

Geologist Looks to Earth’s Past for Hints of Earth’s Future
By Justine Hofherr
BU News Service
In his quest to understand earth’s history, Professor Sam Bowring has traveled to Siberia, Poland, India and China. He has been chased by a black bear for four hours through the Northwest Territories of Canada, eventually ridding himself of the beast by shooting a flare gun into its eye. He has stared into the eyes of a mountain lion all night long in the scrub brush desert of New Mexico, wielding only a small knife and hammer, eventually dozing off as his campfire cooled and awaking to the sound of the lion’s screams in the distance.
Bowring is, first and foremost, a geologist—and he has a mystery to solve.
The adventures the Indiana Jones of geology encounters, whether he’s gathering rocks in South Korea or geomapping in the Cascade Mountains of Washington, are a bonus.
“I’m interested in the origin and evolution of the Earth’s crust,” Bowring said, sitting at his office desk in MIT’s Green Building, the tallest building on the Cambridge, Mass., campus.
Bowring, with bright sapphire eyes and a thick gray beard, has a quiet, serious demeanor as he discusses his work. Behind him, three metal bookshelves span the length of the room. The shelves are full, and every single title is about geology.
“Work is my hobby,” Bowring said, pausing to adjust the collar of his gray button-down shirt. “I like being outdoors and hiking, but I think about science all the time.”
For the past 20 years, Bowring has spent every day of his life trying to understand precisely when–and why 252 million years ago, at the end of the Permian Period, 96 percent of earth’s life disappeared.
Bowring and his colleagues traveled to a set of hills in China where there are rocks from the late Permian, early Triassic period. These rocks contain layers of fossils that show the scientists when certain species went extinct. Not only are there fossils preserved in these rocks, but there is also volcanic ash.
It is a mineral—zircon—in the volcanic ash that proves most useful to Bowring.
Bowring separates zircon, a brownish translucent mineral, from the ash because it has a special property.
When zircon forms in the newly spewed ash, the element uranium fits into the crystal structure quite nicely, he said. But lead does not—it’s radiogenic, meaning, it’s produced by radioactive decay.
“So the day that crystal forms, you have a clock,” Bowring said. “That clock is based on the decay rate of uranium to lead. By measuring that ratio, we can calculate the age of that ash quite precisely.” Bowring smiles as he makes this point.
Bowring thinks that by narrowing the time frame of this mass extinction, he and his colleagues could shed light on what factors might have caused it, possibly exposing parallels between what the environment looked like then, and now.
“Studying this is interesting because this is the largest extinction that animal life has seen on this planet,” Bowring said. “As we push to shorter and shorter time scales, it starts to be relevant to our own existence on this planet and what we’re doing to it.”
Recently, Bowring and his colleagues had a breakthrough thanks to increased precision in measuring rocks—they published a report in January for the Proceedings of the National Academy of Sciences definitively stating that the mass extinction took less than 60,000 years.
While 60,000 years might seem like an incredibly long time to humans, in geology, this is a blink of an eye and means the extinction took place much more rapidly than previously thought.
Bowring describes this knowledge as “sobering” because the scientists have found a clue—spikes in carbon dioxide—that correlates with this narrowed time frame.
“When you look at the fossil record, you see fossils begin to disappear based on physiology and their ability to deal with high CO2 emissions,” Bowring said.
Animals, the ones who “sat in the mud and filtered water,” were the first to go, he said. They just couldn’t handle the accelerated rate of CO2 emissions. The last animals to disappear from the fossil record were the more active organisms.
Another clue Bowring has noted is that right after the extinction, animals couldn’t precipitate shells made from calcium carbonate very easily.
“There’s a dearth of shells in the fossil record,” Bowring said.
A simple way to inhibit the precipitation of calcium carbonate is to drop the pH, or acidity, of seawater.
“Today, people are very concerned that the pH of sea water has dropped about a tenth because of high carbon emissions,” he said.
Though Bowring and other scientists have thus determined that the mass extinction correlates with high CO2 levels and low pH levels in the ocean, they still struggle to understand precisely what could have caused this.
They do know that mammoth volcanoes in Siberia called the Siberian Traps were burping lava around this time for about a million years, spewing between three and 10 million cubic kilometers of scorching lava over the earth. Between three to five million cubic kilometers is enough to put a kilometer of lava over entire the entire United States—so that’s a lot.
While volcanic eruptions, even minor ones, can be responsible for sharp spikes in CO2 emissions, Bowring is not satisfied placing blame solely on the Siberian Traps.
“Timing is crucial,” he said. “We know that the Siberian Traps overlap with the extinction, but their eruption took place over a million years. Why, then, did the extinction take only tens of thousands of years?”
This question continues to puzzle Bowring and other scientists—perhaps the extinction was the result of a combination of factors, and the eruption of the Siberian Traps pushed the majority of life’s adaptation capabilities over the edge. But the lack of certainty doesn’t mean they won’t stop trying to narrow the time frame for further clues.
After all, there are no “absolutes” in science, Bowring said.
“I suspect that in the next year we will make that time frame much smaller,” he said.
Regardless of finding the exact cause of the extinction, Bowring believes the raised levels of CO2 from the end of the Permian Period reflect Earth’s current state, but the levels have been rising at a much accelerated pace.
The driving force of climate change, the high emission of CO2 through the burning of fossil fuels, has taken a phenomenon that occurred over tens of thousands of years and has put it on a decadal time scale.
By the mid 21st century, the magnitudes of projected changes for global temperature shift will be substantially affected by the choice of emissions scenario, according to the 2013 Intergovernmental Panel on Climate Change. The panel also noted that it is “extremely likely” (greater than 95 percent confidence) that most warming between 1951 and 2010 was human-caused.
This information is depressing, Bowring said, but what’s more depressing is that humans aren’t prepared to change their actions accordingly. Young people are taught that the only successful economies are ones that grow, and they grow at the expense of burning fossil fuels, a quick energy fix that is unsustainable.
This is largely because people only think about climate change on a very small time scale—“How can you expect people to make intelligent decisions about climate change when half the population thinks Earth is less than 10,000 years old?” he said.
In this vein, Bowring thinks a start to solving the problem involves better Earth science education at high schools and universities.
Many Earth science programs have been cut from course curriculum at public schools—even in Massachusetts, a state at the forefront of cutting-edge scientific research, he said.
Furthermore, taxpayers in 14 states will bankroll nearly $1 billion this year in tuition for private schools, many of which are religious and teach that the Earth is less than 10,000 years old, according to Politico.
While public schools cannot teach creationism or intelligent design, private schools receiving public subsidies can and still do. This is fundamentally at odds with students understanding the history of Earth’s environment, and therefore prevents them from understanding the challenges faced in our current environment, Bowring said.
“Anyone who will listen about geologic time and the importance of understanding evolutionary history and applying those lessons to the hard future, that’s really important,” Bowring said. “We don’t do enough of it.”
Bowring said when he thinks about his life’s accomplishments, he’s most proud of the students he has produced who are interested in solving similar problems. He can tick off the names of five students who are now teaching geochronology at various universities around the United States.
“Your scientific achievements—they are just flashes in the pan,” Bowring said. “You’ll get a newspaper article published, but 30 years from now, no one will remember that.”
Julia Baldwin, an assistant professor at the University of Montana, is a former student of Bowring. She took his geochemistry class and he encouraged her to get involved with geochronology research in Saskatchewan, a prairie province in Canada.
When you’re in the field with Bowring, Baldwin said in a phone interview, you collect ten times more rocks than any other day. He encourages students to pull out their giant rock hammers to hack away at rocks, filling their backpacks till they weigh 50 pounds, she said with a laugh.
“He’d say, ‘You might never see this rock again!’” Baldwin said in a phone interview. “He’s just so excited about everything you see.”
Besides his passion for science, she said she was struck by how committed he was to his students.
Completely devoted to undergraduate education, Bowring goes out of his way to lead field trips to Yellowstone National Park before classes start, Baldwin said. That’s how he gets students so excited about geology, she said—he actually gets them outdoors looking at it.
“He puts a lot of responsibility in students’ hands,” Baldwin said. “He first gives you the knowledge then says, ‘Go do great things with this.’ But he doesn’t take credit for it—he just doesn’t have an ego like that.”
Like Bowring, Baldwin also thinks a greater emphasis on earth science education needs to exist, from kindergarten to college.
Students need an understanding of deep time and what it means in order to evaluate the present day climate problems, Baldwin said.
“Students should make decisions with a ‘scientific citizen’ mindset, and be able to evaluate basic science and climate change within the context of geologic time,” she said. “The more they can come into contact with this knowledge, the better.”
Like Baldwin, Professor Ethan Baxter at Boston University said Bowring is a “remarkable” individual, imparting critical earth Science knowledge to his students.
Besides citing him as “the best zircon geochronologist in the world,” Baxter calls Bowring “a good doobie in general.”
Baxter is also a geochronologist, studying the formation of earth’s crust. Instead of zircon, however, Baxter uses garnets to date time.
Fingering a garnet that sits atop his office desk in the Stone science building on BU’s campus, Baxter explains the magic of unlocking the stories that each mineral holds about earth processes—processes related to the past and present.
“Anyone that studies earth history is always thinking about how can we take our information that we have from the past over those tens, to hundreds of thousands, to millions of years time scale, and then apply that to what’s happening today on the decadal time scale,” Baxter said.
Similar to Bowring’s findings in the Siberian Traps, Baxter has found evidence that links spurts of garnet growth around the world with ancient increases in CO2 emissions.
Though he acknowledges that there is still no “smoking gun” in relation to what caused the mass extinction in the Permian Period, Baxter said Bowring’s efforts to narrow the time frame have shown, increasingly, that there are great similarities between the environment then and now.
“Sam’s work with the methods they are using for zircon, he’s reached a resolution in time, which transcends everything we’ve ever dreamed of,” Baxter said.
But despite great leaps in scientific discovery, education lags behind, he said.
When you’re talking about pressing matters like climate change, resource depletion, water quality, sea level rise and the melting of the Arctic ice cap, Baxter said, you notice that comprehension starts with having a basic understanding of earth science.
“A lot of states don’t include it anymore,” Baxter said of earth science education. “It’s a real shame. I don’t think people have a disinterest—they have a lack of awareness.” | <urn:uuid:5e3e556f-ff18-4599-a422-e34742ba0491> | CC-MAIN-2024-51 | https://archive.bunewsservice.com/tag/earth-science/ | 2024-12-04T15:52:55Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066181697.67/warc/CC-MAIN-20241204141508-20241204171508-00200.warc.gz | en | 0.965703 | 2,888 | 2.703125 | 3 |
In today’s business environment, both the internal and external environment changes frequently. To cope with the internal and external environment changes, organisations frequently have to bring change management to embrace the changes positively and use it as a facilitating device for organisational growth. This report sheds light on different aspects of change management. Apart from discussing change management theories, the report also talks about the resistance to change management. Finally, the report also sheds light on the benefits and ways that change management can most effectively and efficiently occur in the organisation.
When there is a complex hierarchy in concealed order, it is called the study of complexity theory. From the definition of complexity theory, it is apparent that management needs complexity theory to bring change to the organisation. Complexity theory is required to bring change management into the firm so efficiently that everybody in the organisation recognises the positive aspects of the changes.
Bringing strategic change through complexity theory
There are many hidden benefits of complexity theory that can help the firm experience change management without losing confidence among the firm’s people. The characteristics of the complexity theory ensure that the organisation experiences proper change management without any delay (Feldwick, 2006). There are many characteristics of complexity theory that enable change management in the organisation so that the manager faces no hassle in implementing this. The following texts describe those characteristics of complexity theory.
(i) Spontaneity of self-organisation
The organisation is made spontaneous by enabling complexity theoretical application inside the organisation. In an organisation where a complexity approach is there, the elements of the organisation can communicate easily. Moreover, the organisation’s people are virtually together when the approach is applied in an organisation. The communicating system is less structured so that all the elements can be easily communicated within the least time possible. The system is made informal too. This also intrigues more communication among the stakeholders. Spontaneous communication efforts make the organisation self-reliant, which paves the way for better change management. Managerial jobs can well be distributed with this characteristic of complexity theory. Planning of the changes can be implemented, and the control system becomes more transparent. This also helps the organisation to implement change management fast. Disputes also are lessened as the transparent and self-organisation system tends to reduce employee conflicts.
(ii) Decentralized control system
The complexity approach does not involve any master key to the control system. This increases the efficiency of change management. Through this approach, the system is made more cooperative so that all the stakeholders can work together. Keeping no key controller in the system enables the decision-making process faster (Clow and Baack, 2010). The complexity theory enables a sense of competition among the people inside the organisation, which increases teamwork. Hence, there is no need for autocratic management where a person is all in all. This increases the efficiency of the tasks. The power is not centralised, and the employees are empowered according to their eligibility. The fair process of power distribution makes the organisation more viable.
(iii) Imperfect estimation of project output
Though there are many positive characteristics of the complexity theoretical approach, there is a negative aspect of it too; that is, the theory cannot predict the output of the whole system. As the number of interactions among the organisation’s people is many, it is difficult to project the output individually. The managers hence face the problem of certainty of the project. As the number of interactions is vast, it is very tough to estimate the outputs that each connection creates. Moreover, the control management is not centralised. Due to this issue, connections might not always be positive, though there are fewer numbers conflicts. However, it does not mean that all the connections create positive outputs for the organisation’s change management. However, there is a way to tackle this problem. The manager should plan for better connectivity, and the transparency should be more on the connections so that each connection’s produced outputs can be measurable.
(iv) Applicability of complexity theory in business
Innovative businesses are embracing complexity theory nowadays. In order to implement innovative change management, it is better to implement complexity theory in the organisation. Today’s competitive world requires firms to be innovative in their change management issues. Hence, complexity theory is the prerequisite now for the firms’ change management implementation. Real-life implications of change management are challenging as many internal and external factors to work against the change management’s implementation. Though there are negative aspects of complexity theory, the positive aspects outweigh the negative ones. Hence, in this competitive business world, it is necessary to bring complexity theory to change management. The linear structure of change management requires continuous efforts from the internal management to take less time to be implemented. Complexity theory allows the management to implement the change faster and in a more reliable way.
The reasons for taking complexity theory for change management by most managers
The strategic change in the organisation requires many efforts from the managers. Due to the nature of complexity theory, it is easier to implement in the organisation. Irrespective of a firm’s type, the complexity theoretical approach is smoothly implemented in the system. It also takes less time to understand the people inside the organisation. There are, of course, other theories for change management (Brondoni, 2010). However, in implementing strategic change in the organisation, complexity theory is the best one for this competitive business world where there is no time for the next move. Besides, change management through complexity theory is better as it takes place in a linear approach. The systematic approach to the theory allows the managers to get feedback from the change management very efficiently. Employees of the firm understand the system faster, and hence they start to work faster. This again improves the effectiveness of change management. The current situation of the organisation might prevent change management in the organisation. However, through complexity theory applied in the organisation, the internal and external factors become less influential in preventing change management. Hence, it also paves the way for better change management in no time in the organisation. Complexity theory includes simulation practices that also ensure better change management, and it also occurs faster than any other theories available in bringing desired positive change in the organisation (David and Markowitz, 2011).
Bringing change is not an easy task to do. Many factors prevent a change to take place in the organisation. There is resistance to change management. From various groups in the organisation, resistance to change takes place. Change provides positive impacts on the organisation. However, this might not be the case all the time. Some of the groups might get initial problems due to changes being implemented. Hence, they create resistance to change. This type of resistance can create many problems in implementing the changes in the organisation. The effective implementation of the changes might also be hampered due to the organisation’s resistance to various groups.
Why the resistance to change affects the implementation of the organisational change
From the pool of reasons why there is resistance to change, we should first examine why people tend to resist change management.
(i) Fearing the unknown: People generally do not like change because they had a prior fear that the changes might hamper them or not accept the change. Their performance might be dissatisfactory with the changes – that is what they fear about bringing change in the organisation. There are many possible ways that the employees might fear that their positions are in danger due to changes being implemented in the organisation (Fill and others, 2009). For example, when the manager plans to set up new technology in the manufacturing plant, the employees might resist the change due to the fear that their jobs are at risk. Anticipated fears are not always valid.
(ii) Unwilling to bring change: All the firm’s stakeholders might not feel the necessity of the changes. Some may see change as unnecessary for the organisation, where it is true that change is inevitable for a successful organisation. Some of the people in the organisation might feel that the existing setting is just doing fine (Dechernatony, 2007). However, just doing fine is not satisfactory for organisational growth. Change smoothens up the work procedures. However, some of the employees might feel that the changes might hamper the efficiency level, which is untrue.
(iii) Changes might not bring the required need fulfilment to the employees: While most views change as the medium to fulfil their requirements, some employees might feel that their required success might be hampered if they change the organisation. Employees have high expectations from their jobs. Hence, they tend to fulfil the requirements through working in the same environment, and when they fear any change, they tend to resist it. However, it should be known that the new environment promises new hope for them.
(iv) Risks overlapping the benefits: Changes might not provide the required benefits that the people in the organisation believe. The accumulated risk might overlap or exceed the employees’ benefits (Getz, 2007). When there is a high risk, the employees will give more effort to implement the change. However, if they do not see many benefits from the changes, they would be disheartened, which might also hamper the employees’ productivity.
(v) Lack of ability to bring the changes: The fear of the lack of ability to bring the change might also be why employees resist change in the organisation. Lack of confidence in bringing the changes hampers the change management (Duncan, 2005). The employee might also call for the full discharge of the changes that take place. Cooperation from those employees is not possible in that position. This has a far-reaching consequence as the employees would not also receive benefits from the organisation, which does not grow due to non-implementation of changes in the organisation. The employees ultimately become dissatisfied with their efforts being gone in vain (Gedenk and Neslin, 2009).
(vi) Fear of change being a failure: Most employees fear that the changes might not work in the desired way that the firm has planned. The changes might not be fruitful. Hence, the changes might not bring any benefits to the organisation (Damm, 2012). Hence, the employee would not want to give much time to something they believe will benefit the organisation.
(vii) Fear of failure to maintain the changes: Keeping the change management process is a huge task. Some of the employees might not be interested in doing so in the long run. Hence, they might not want to bring any changes in the organisation that would overburden their workload.
(viii) Fear of bringing inconsistent change to company values: The changes that are not well communicated to all the stakeholders might face the problem that some of the employees might feel the anticipated changes will go against the existing values and principles of the organisation’s mission and vision (Allen, 2008). The potential changes would cause productivity to be lowered in no time—that is, the employees’ belief when the desired change is not well communicated.
How resistance to change affects the implementation of the organisational change
Resistance does not let change management take place. Resistance is the major reason why the planning, endeavouring, and efforts to change management fails. The following texts depict how resistance to change affects the organisation that wants to bring in changes (Clow and Baack, 2005).
(i) Ill-development of the change management: It is very difficult for human resource management to bring changes as it requires a good deal of procedures from time to time. Only a structured and systematic manner can bring positive changes for the organisation. Reviewing the process, again and again, is very crucial to the success of change management. By motivating higher inputs to the employees, the human resource management must keep the employees up and do the change management (Burmann and Zeplin, 2005). The focus of control should be maintained by providing necessary training and development programs for the employees from time to time. If the human resource management does not recognise the needs of the employees while bringing change, the resistance would be very high. The organisation would not face the success of change management in the organisation, no matter how much efforts are given by the top management (Clow and Baack, 2012).
(ii) Making a vague representation of the change management tasks: New tasks and duties to the employees should be made clear. However, the representation of vague duties and responsibilities distributed among the employees about the new tasks would create chaos. When the change management takes place, employees might be assigned new tasks and responsibilities to fulfil. There is a scope of misunderstanding of the responsibilities, and the tasks might be overlapping in some cases. When this mess happens, the whole change management implementation becomes useless as the employees do not understand their roles and duties well.
For an effective organisational change, the management must ensure reasonable efforts in a systematic and desired way. Involving the employees in the change management process is inevitable. Hence, the employees should be trained well to understand the whole process of bringing change management to the organisation (Dann and Mertens, 2004). An effective and efficient change management process requires upper-level management’s involvement in the supervision level, and the employees should be guided well in bringing the change. The following texts discuss how top management can involve the employees to bring change management in the organisation more effectively and efficiently.
Applying Expectancy Theory to the Management
Naturally, an employee of the organisation keeps certain hopes and aspirations from the job he or she is fulfilling. The expectancy theory describes the expectations of an employee from the roles and responsibilities that he or she carries out. From the perspective of the expectancy theory, the managers must involve the employees with the change management so that they feel important in the process (Bamford, 2001). Their social and psychological expectations would be fulfilled then. They should understand that they would grow exponentially through change management, and their career in the organisation will get a facelift. When managers would consider applying expectancy theory during the change management process, the employees would be self-driven to bring the changes in the organisation.
Little steps for the big leap
The employees should be provided with small targets first, and then they should also be offered something in exchange. Bringing change would require a lot of monetary and non-monetary motivation. The organisation should be ready to fulfil that. Giving the most out of the benefits from the change management should be the aim of the managers (Clow and Baack, 2004). When the employees would feel that it’s their responsibility to outperform their previous records in order to receive better benefits from the organisation, the change management process would be facilitated in a better and structured way.
Applying the Equity Theory for Better Change Management
There are many barriers to change management, as we have discussed earlier. Employees tend to be resistant, and they might also encourage others to join their resistance to change. In order to tackle the situation, the managers should come up with some equal payment and treatment plans for the employees. This should again be made on the ground of eligibility so that the employees do not feel biased. Disparity should not be allowed in any form in the organisation. Dissatisfaction might occur when the firm does not recognise the long-term demands from the employees. Before bringing change, the managers must ensure that there is no sense of dissatisfaction among the employees. Only then the employees would work hard to bring change to the organisation for their betterment.
Involving Employees to the utmost
The major resource of an organisation is the employees that they have. When the employees are involved well in the change management process, it is apparent that the process would succeed no matter which resource the firm lacks. The employees should understand that only the organisation will not grow better due to the change management that the top management has planned; rather, the employees would be better benefitted from the proposed change. The employees get the benefits first, and then the overall organisation gets the advantages of change management. Technology has flourished so much that technology is there to help the employees, for example, not harming their position. The employees should embrace change for their betterment. There should be ample time spent before launching the change management program to educate the employees about the benefits and advantages they would receive due to implementing the necessary changes for their career growth.
Throughout the discussion, it has been apparent that change is inevitable, no matter how much a firm tries to avoid it. Change management is the approach that leads the organisation to embrace the change for the betterment, in a better way, removing the negative aspects of change that will occur in the organisation. Communication is the key to bringing better change management in the organisation. Hence, better management should involve more communication plans for the employees before launching the change management process.

Beijing’s One Belt One Road (OBOR) initiative, a vast infrastructure project that aims to connect China with the rest of the world, including Europe and Africa, is a prime example of China’s strategic approach to geopolitics.
In August 2021, the Taliban seized power in Afghanistan, ending two decades of US occupation and nation-building.
Taken together, these diplomatic eruptions represent a tectonic shift in the balance of power in Eurasia, with the US losing ground to China and other rising powers.
China’s $400-billion infrastructure deal with Iran and its position as Saudi Arabia’s top oil supplier positioned Beijing to broker a major diplomatic rapprochement between the two bitter regional rivals, Shia Iran and Sunni Saudi Arabia.
The island nation is a key strategic prize for both China and the United States, and a Chinese takeover of Taiwan would be a major blow to Washington’s strategic position in the Pacific.
The Legacy of World War II and the Modern Geopolitical Landscape
World War II was a defining moment in world history. The conflict was marked by tremendous violence, destruction, and loss of life, as well as the rise of America as a global superpower. The war had far-reaching geopolitical consequences that continue to shape the world we live in today. The strategies used by American military leaders during the war, such as George Marshall, Dwight D. Eisenhower, and Chester Nimitz, were aimed at gaining control over the vast Eurasian landmass. The objective was to constrict the reach of the Axis powers globally and ultimately gain global hegemony.
The Impact of World War II on Modern Geopolitics
The legacy of World War II still resonates today, as its consequences continue to shape the modern geopolitical landscape. The strategies and tactics used during the war continue to influence global political and economic relations. As Washington encircled Eurasia to win the war, Beijing is now engaged in a more subtle form of that same reach for global power.
The Relevance of World War II Today
The lessons of World War II are still highly relevant today, as they provide valuable insights into the nature of global power and the ways in which it can be acquired and maintained. The legacy of the war continues to shape the way in which nations interact with one another, and it is important for policymakers to understand the geopolitical strategy dynamics that emerged from that conflict.
The Cold War Strategy: A Blueprint for American Geopolitics
The lessons learned during World War II were not lost on America’s military leaders and policymakers. They recognized the need to contain the spread of communism, which led to the creation of the Cold War strategy. This strategy involved economic aid, military alliances, and a system of military bases to contain the Soviet Union and its allies. Let’s delve deeper into this strategy and how it has influenced American geopolitics over the past 70 years.
The Marshall Plan and NATO
Secretary of State George Marshall’s $13 billion Marshall Plan, launched in 1948, aimed to rebuild Western Europe after the devastation of the war. This economic aid was critical in the creation of the North Atlantic Treaty Organization (NATO), a military alliance formed in 1949 that served as a bulwark against Soviet expansion. The formation of NATO was a response to the Soviet blockade of Berlin and the Czechoslovakian coup in 1948.
Military Pacts and Strategic Hinges
President Dwight D. Eisenhower continued this strategy by signing a series of mutual-security pacts with South Korea in 1953, Taiwan in 1954, and Japan in 1960. These pacts established a chain of military bastions along Eurasia’s Pacific littoral, known as the “island chain,” which served as the strategic hinge for American global power. The island chain was critical for both the defense of North America and dominance over Eurasia.
The Cold War Legacy
The Cold War strategy established the United States as a global superpower and created a world order that lasted for over 70 years. The strategy was successful in containing the spread of communism, but it also led to military interventions in Korea, Vietnam, and other parts of the world. The legacy of this strategy is still felt today, as the United States continues to maintain a global military presence and alliances with countries around the world.
Understanding the Limitations of Global Hegemony
Zbigniew Brzezinski was a political scientist and foreign policy expert who advised two US presidents. His book, The Grand Chessboard, is a seminal work on geopolitics that offers insights into how the US should conduct foreign policy in the post-Cold War world. Brzezinski argued that the US, despite being the world’s sole superpower, had inherent limitations in its global hegemony. This perspective is relevant even today as we witness the changing dynamics of global power.
Shallow Hegemony: A Critical Analysis
According to Brzezinski, the US hegemony was inherently “shallow” because it rested on the presumption of American exceptionalism and superiority. He believed that the US needed to be aware of its limitations and adjust its policies accordingly. Brzezinski’s insights were critical of the triumphalist rhetoric that characterized US foreign policy in the 1990s.
The Importance of Geopolitics
Brzezinski emphasized the importance of geopolitics in shaping foreign policy. He argued that the US needed to maintain its strategic position in Eurasia, which he called the “grand chessboard.” He believed that controlling the Eurasian landmass was essential for US global hegemony. Brzezinski’s insights remain relevant today as China rises to challenge US power in the region.
China’s Strategic Approach to Geopolitics
China’s growing influence over Eurasia has resulted in a significant shift in the continent’s geopolitical strategy landscape. The United States, under the assumption that China would conform to its global rules, admitted China to the World Trade Organization (WTO) in 2001. However, this decision proved to be a major strategic error, as China’s rapid economic growth led to a massive increase in its annual exports to the United States, and a significant rise in its foreign currency reserves.
Despite its economic growth, China’s geopolitical ambitions were still not fully understood by the US foreign policy establishment. Beijing’s One Belt One Road (OBOR) initiative, a vast infrastructure project that aims to connect China with the rest of the world, including Europe and Africa, is a prime example of China’s strategic approach to geopolitics. The project has already seen significant investment in infrastructure development across Central Asia and Africa, and is poised to continue expanding its reach.
As China’s global power continues to rise, the US will have to reassess its strategic approach to Eurasia. This will require a better understanding of China’s geopolitical strategy ambitions and the development of a more nuanced approach to dealing with the country. While the US may no longer be the dominant global power, it can still play a critical role in shaping the geopolitical landscape of the 21st century.
China’s Belt and Road Initiative: A Geopolitical Power Play
In 2013, China’s President Xi Jinping initiated a trillion-dollar project, known as the Belt and Road Initiative (BRI), with the goal of transforming Eurasia into a unified market. The initiative involved the creation of a vast infrastructure network of rails and pipelines, which would connect China to Europe and Africa, while also serving as a means of consolidating China’s geopolitical strategy power over the region.
As part of this initiative, China built a chain of 40 commercial ports around the world, extending from Sri Lanka in the Indian Ocean to Europe. These ports, which are strategically located along the tri-continental world island, have enabled China to expand its economic influence and gain access to key resources and markets.
The BRI has been described as the largest development project in history, dwarfing even the Marshall Plan. However, the initiative has been met with mixed reactions from the international community, with some countries viewing it as a positive opportunity for economic growth, while others see it as a means for China to exert its influence and control over the region.
Critics of the initiative have raised concerns about the lack of transparency, environmental impacts, and the potential for debt traps for participating countries. Despite these concerns, China’s BRI continues to forge ahead, solidifying its position as a global economic and geopolitical power.
The United States has been facing significant geopolitical changes in recent years due to China’s growing economic and political influence in Eurasia. As a result, the US is experiencing a loss of influence in the region, which is manifesting itself in a series of diplomatic challenges. In this article, we will explore four recent diplomatic challenges that have been driven by these tectonic shifts in the region.
Challenge 1: The Iran Nuclear Deal
In 2015, the US and several other world powers reached a landmark agreement with Iran aimed at curbing its nuclear program in exchange for sanctions relief. However, in 2018, the Trump administration withdrew from the deal, citing concerns about Iran’s non-nuclear activities and re-imposed economic sanctions. This move was seen by many as a strategic blunder, as it isolated the US from its European allies and allowed China to step in and deepen its economic ties with Iran.
Challenge 2: The Afghan Peace Process
The US withdrawal from Afghanistan in 2021 marked the end of a 20-year military presence in the country. Despite spending billions of dollars and sacrificing thousands of lives, the US was unable to achieve its stated objectives in the region. This failure has undermined US credibility in the eyes of its allies and adversaries alike, and has opened up space for China to deepen its economic and political influence in the region.
Challenge 3: The Nord Stream 2 Pipeline
The fourth diplomatic eruption is the most recent and arguably the most consequential for US power projection in Eurasia. In August 2021, the Taliban seized power in Afghanistan, ending two decades of US occupation and nation-building. While the Taliban’s ascendancy has taken most observers by surprise, it is yet another sign of the accelerating shift in Eurasian geopolitics. As Beijing ramps up investment in the war-torn country, Washington’s global influence continues to wane.
Taken together, these diplomatic eruptions represent a tectonic shift in the balance of power in Eurasia, with the US losing ground to China and other rising powers. While the US still holds significant military and economic power, its ability to shape the course of events in Eurasia is being increasingly challenged. As the geopolitical substrate continues to evolve, the US will need to adapt its strategy to stay relevant in an increasingly multipolar world.
Tectonic Shifts Shake US Power: How China’s Economic Expansion is Changing the Geopolitical Landscape
The past few years have seen a series of geopolitical strategy changes that are erasing US influence across Eurasia. Beijing’s relentless economic expansion and massive development deals with surrounding Central Asian nations have left US troops isolated in Afghanistan, leading to the country’s sudden withdrawal in August 2021. This was followed by Russia’s massing of troops on Ukraine’s border, a move that aimed to weaken the Western alliance and undermine NATO’s influence.
Beijing and Moscow: A New Strategic Partnership
Putin visited Beijing to court President Xi’s support before massing troops on Ukraine’s border. The two leaders issued a joint declaration, denouncing the further expansion of NATO and declaring that their relations were superior to political and military alliances of the Cold War era. Putin’s invasion of Ukraine in March 2022 resulted in Russia’s diplomatic isolation and European trade embargoes, prompting Moscow to shift much of its exports to China. This move quickly raised bilateral trade by 30 percent to an all-time high, while reducing Russia to a pawn on Beijing’s geopolitical strategy chessboard.
The Sectarian Divide in the Middle East: A Major Diplomatic Rapprochement
China’s $400-billion infrastructure deal with Iran and its position as Saudi Arabia’s top oil supplier positioned Beijing to broker a major diplomatic rapprochement between the two bitter regional rivals, Shia Iran and Sunni Saudi Arabia. Within weeks, the foreign ministers of the two nations sealed the deal with a symbolic voyage to Beijing. This unexpected resolution of the sectarian divide that had long defined the politics of the Middle East left Washington diplomatically marginalized.
France and China: A Global Strategic Partnership
Finally, the Biden administration was stunned by French President Emmanuel Macron’s recent visit to Beijing. After signing lucrative contracts with French companies, Macron announced “a global strategic partnership with China” and promised he would not take cues from the US agenda over Taiwan. While a spokesman for the Élysée Palace released a clarification that the US is France’s ally with shared values, Macron’s declaration reflected both his own long-term vision of the European Union as an independent strategic player and the bloc’s ever-closer economic ties to China.
The geopolitical landscape of the world is rapidly shifting, and the future of global power is up for grabs. China’s rise to power has been nothing short of meteoric, and it appears that it is now poised to execute a deft geopolitical squeeze-play on Taiwan, which could ultimately break the US strategic frontier along the Pacific littoral.
China’s preferred mode of exerting geopolitical pressure is through stealthy, sedulous means, rather than the “shock and awe” of aerial bombardments favored by the United States. This was exemplified by China’s incremental approach to building its island bases in the South China Sea. By gradually dredging, building structures, constructing runways, and eventually emplacing anti-aircraft missiles, China was able to capture an entire sea without any confrontation.
China has built its economic-political-military power in a little more than a decade, and if it continues to increase at even a fraction of that head-spinning pace for another decade, it could execute a deft geopolitical squeeze-play on Taiwan. This could involve a customs embargo, incessant naval patrols, or some other form of pressure, causing Taiwan to quietly fall into Beijing’s grasp.
If this were to happen, the US strategic frontier along the Pacific littoral would be broken, possibly pushing its Navy back to a “second island chain” from Japan to Guam. This would be the last of Brzezinski’s criteria for the true waning of US global power. Washington’s leaders could find themselves sitting on the diplomatic and economic sidelines, wondering how it all happened.
It is clear that China’s rise to power is not just about its military might, but also about its economic and political influence. China has signed massive development deals with Central Asian nations, and its trade with the United States was worth a staggering $500 billion in 2021. This has enabled China to expand its geopolitical influence throughout Eurasia, leaving the US isolated in Afghanistan.
China has also brokered a major diplomatic rapprochement between the bitter regional rivals, Shia Iran and Sunni Saudi Arabia, and established a “global strategic partnership” with France, promising not to take its cue from the US agenda over Taiwan.
The future of geopolitical power is uncertain, but one thing is clear: China’s rise to power is changing the world as we know it. The United States must adapt to this new reality or risk losing its place as a global superpower.
The geopolitical power struggle between the United States and China is one of the most pressing issues of our time. At the center of this struggle lies Taiwan, a small island nation in the Pacific that is coveted by both superpowers. While Washington has historically been Taiwan’s ally and protector, Beijing has been steadily building its economic, political, and military power in the region, and could potentially execute a deft geopolitical squeeze-play on Taiwan in the near future. In this article, we will examine the future of geopolitical power and the potential consequences of a Chinese takeover of Taiwan.
The Chinese Approach: Stealthy and Sedulous
Unlike the United States, which has historically relied on “shock and awe” tactics to achieve its geopolitical strategy goals, China has taken a more stealthy and sedulous approach to expanding its power. This approach is evident in China’s incremental expansion of its island bases in the South China Sea. Instead of launching a full-scale military invasion, China began by dredging the sea floor, then building structures, runways, and finally emplacing anti-aircraft missiles. By taking these incremental steps, China was able to avoid a confrontation with the United States and its allies while effectively capturing an entire sea.
The Uncertain Fate of Taiwan
As China’s economic, political, and military power continues to increase at a head-spinning pace, Taiwan’s fate looks increasingly uncertain. The island nation is a key strategic prize for both China and the United States, and a Chinese takeover of Taiwan would be a major blow to Washington’s strategic position in the Pacific. While the United States has historically been committed to defending Taiwan, its ability to do so in the face of Chinese power is far from assured.
The Potential Consequences of a Chinese Takeover
If China were to successfully execute a deft geopolitical strategy squeeze-play on Taiwan, the consequences for the United States could be significant. One of the key criteria for the true waning of US global power, according to the late strategist Zbigniew Brzezinski, is the breaking of the US strategic frontier along the Pacific littoral. A Chinese takeover of Taiwan would likely push the US Navy back to a “second island chain” from Japan to Guam, effectively breaking this strategic frontier and signaling the waning of US global power.
It is evident that geopolitical power remains a critical issue that shapes the modern world. The lessons of World War II and the Cold War continue to inform current policies, and the shifting balance of power between the US and China is a significant challenge that must be addressed. Understanding the limitations of global hegemony and the importance of strategic positioning is crucial in navigating the complexities of international relations. It is imperative for policymakers to prioritize peace and prosperity for all nations and work towards creating a more stable and secure world.

Of all the personality theories we read about this week, I felt that Erik Erikson’s view that adulthood was a continuing developmental process made of various stages (identity formation and ego crises) was the most modern approach to assess personality development. The eight stages of the ego crises are trust versus mistrust, autonomy versus shame and doubt, initiative versus guilt, industry versus inferiority, identity versus role confusion, intimacy versus isolation, generativity versus stagnation, and ego identity versus despair.
There are some aspects of personality development in today’s society that caused me to choose this particular theory. In my personal experience and observations, as children grow and undergo both physical, emotional, and psychological changes, they seem to face the same conflicts and choices in varying degrees that they must overcome. The same holds true for teens and adults. There are times when someone will be perplexed that a peer seems to either be “behind the curve” because they behave immaturely, or haven’t caught up to the same milestones and hallmarks of adulthood as those of similar age…or “ahead of the curve” since they seem more successful, enlightened, or mature than most adults their age. Perhaps these individuals have not successfully worked though one or more of the stages as Erikson outlined.
Erikson’s term of “identity crisis” seems to be a common topic in modern society, as teenagers try to find their way in the world, and even more young adults continue to live at home while they try to become more independent and self-sustaining in today’s world–“finding their way”, so-to-speak. It seems that Erikson’s term could also be paralleled to the idea of one having a “midlife crisis” that could typically occur anywhere between the 40’s to 60’s in age. Perhaps that person will undergo a drastic change in physical appearance, will make one or more extravagant purchases, or make other drastic lifestyle changes such as quitting their job, changing religious affiliations, travelling more, and other indicators that would suggest that they want to rediscover themselves, reinvent themselves, or change their life path before its “too late”.
It seems that the “intimacy versus isolation” stage is a common theme in television, movies, and magazines these days. Some people have difficulty forming strong social or emotional ties with others, or opening up to others to share their “truest self” in the interest of companionship and intimacy. There is a common character portrayed in the media of the “loner”, the “player”, and the “extreme introvert”, which indicates a difficulty in moving successfully through this stage of the ego crises, and makes for interesting plots and conflicts in a story.
Also, many adults would like to think that they are on the positive side of the “generation versus stagnation” stage. People might derive great satisfaction and pride in giving their time, money, or efforts towards others in a positive, productive way, be it through volunteering, donating to a good cause, helping their friend or neighbor, or otherwise giving back to society rather than focusing solely on themselves and their own goals.
Erik Erikson developed an idea that furthered the, then popular, Freudian notion of development of the personality. Rather than discontinuing the growth of personality after childhood, Erikson proposed that personality was an aspect of humanity that continued to develop throughout an individual’s entire lifespan. The Freudian theory may have been appropriate for the industrial era, Erikson’s idea, which eventually became an accepted theory, is what best describes modern society.
Erikson’s theory relies on the basis of identity formation being a lifelong process. This process is comprised of eight “crises” that occur throughout childhood, adulthood, and into the final years of life. These “crises” occur in sequence and are “conflicts or choices” that must be resolved before continuing into the following stage. Unlike the theories of Erikson’s predecessor’s, Stage theory allows for an individual to change. This is an American view point that also suggests that an individual has responsibility over his or her life (Friedman, 2010).
The first of the eight crises presented by Erikson is Trust vs. Mistrust. This beginning stage coincides with Freud’s oral stage (Friedman, 2010). At this time the infant’s main focus is on eating, remaining at a comfortable temperature within differing environments, and defecating regularly. Infants usually rely on their mother’s to provide these needs. Erikson suggests that if the mother successfully provides the needs for the infant, the infant will develop “a sense of trust and hope” and if the needs are not achieved by the mother, the infant will develop “feelings of mistrust and abandonment” (Friedman, 2010). Trust is an issue that currently goes unresolved in many individual’s today. Take for instance, a business man who always assumes the deal will fall though or that his associates are going to take advantage of him. While it may be true that not everyone can be trusted, an over-exaggeration of this notion could be explained by Erikson’s stage theory.
The fifth stage in Erikson’s theory is Identity vs. Role Confusion. This stage corresponds to Freud’s genital stage (Friedman, 2010). During this conflict or choice the individual enters with multiple identities learned from previous stages and emerges as one cohesive individual who has successfully meshed the identities to form one, singular personality (Friedman, 2010). The ideal outcome is an individual with a ” clear and multifaceted sense of self”, while an individual who is unable to successfully complete this stage develops a self-consciousness, “an uncertainty about one’s abilities, associations, and future goals”. Erikson called this “Identity Confusion”. This is a crucial stage in Erikson’s theory and one that is not often achieved in contemporary society. Many individuals graduate from high school and begin college who are still in an identity crisis. They are unsure of who they are and who they would like to become. A new environment leaves them feeling insecure and inadequate. Many college students struggle to discover themselves and merge their previously learned personalities with the reborn self they are striving to achieve. Some individuals are able to complete this stage before they graduate from college and others continue to struggle to figure out who they are.
The final stage of Erikson’s theory is Ego Integrity vs. Despair. This occurs near the end of the lifespan, a time that was not acknowledged as a developmental stage of personality by Freud. At this stage the individual must find wisdom from previous life experiences and is able to look back on his or her life and see “meaning, order, and integrity” (Friedman, 2010). Ideally, the individual’s reflections are peaceful and pleasant, and the individual can continue to pursue their goals that they have built upon for many years (Friedman, 2010). Should this reflection not occur in this manor the individual will be left with a sense of despair. They would feel as if they had not accomplished their goals in life, and would feel as if there were not enough time left to do so (Friedman, 2010). This is a pivotal, final moment of growth for an individual. The successful completion of this stage would yield a continuation of a content sense of self, while they later could be irreversibly devastating. Elderly individuals in modern society undergo a gigantic life change when they enter retirement. When the elderly person is content with their accomplished life goals, he or she continues to be a productive part of the family unit and interacts and offers words of wisdom to grandchildren. They may not always be happy, but generally they are at peace with who they are and what they have done. An elderly individual who enters retirement who has not successfully completed this stage may lash out at family members and avoid social activities all together. They reminisce about times that have gone by and rather than enjoying the memories while remaining in the moment, they got lost in what could have been, or should have been.
A balance of each positive and negative outcome is optimal for a well developed personality according to Erikson. At each stage, one of the two characteristics should be dominant, ” but true maturity includes rather than excludes the other pole” (Friedman, 2010). This notion of balance is incorporated in everyday life, nature, and most philosophies spanning the generations of humanity.
Erikson’s theory is not simply a stagnant outline for changes in personality at defined ages. Erikson emphasized the importance that culture and society play on the individual (Friedman, 2010). This is what allows the stage theory to remain current and to still have the greatest use in understanding and explaining personality development in contemporary society.
I think Alfred Adler’s individual psychology theory is the most useful in understanding personality development in contemporary society. Adler’s theory talks about how people have their own special motivations that vary between individuals and that an individual’s “perceived niche” is rather important (Friedman 2010). The basis of Adler’s theory is that when people are often in situation in which they cannot control their surroundings or what is happening to them, they develop an inferiority complex; an individual with an inferiority complex does not apply themselves due to the belief that they are incapable of succeeding. Inferiority complexes may give rise to superiority complex in order to compensate for the low self-esteem, which can lead to poor relationships and connections. Adler’s theory includes an aspect regarding aggression in which he claims that “an individual is driven to lash out against the inability to achieve or master something, as a reaction to perceived helplessness” (Friedman 2010). According to the individual psychology theory, a child is born inferior because they must rely on the care of others to survive, and as the child ages they work toward becoming more independent, therefore superior.
Alder also believed in four temperaments, choleric, sanguine, melancholic, and phlegmatic, which are learned young. I chose this theory of development because I feel that it is a good picture of our current society. As infants, we can not function on our own and must rely on our parents to survive; as we grow older we start to slowly gain independence from our parents. The problem pops up when something happens to hinder the transition from childhood (inferiority) to adulthood (superiority). Adler’s theory arose from his experience as a sickly child, but the theory may apply to a range of circumstances. Someone who is disabled may develop an inferiority complex, likewise someone who is bullied frequently may fall victim to it. I think that this theory of development makes way for differences among people, therefore can be widely used. I also believe that Adler’s approach to development is very successful at explaining ambition and the lack of.
Growing up I was bullied because I am on the bigger side, which led me to have poor self-esteem; as I got older I started to feel like everybody else was better than me because they were thin. Now that I am an adult, I no longer feel inferior to everyone else, but I did have a hard time coping with the inferiority complex that I held as a teenager. My story is just one way in which Adler’s theory is relevant in today’s society, but the basis of the it is the variation from one individual to the next. I think this theory accounts for why a lot of people develop strong ambitions and why others do not seem to try. I think the one thing that is lacking in Adler’s theory is that it only focuses on feelings of inferiority and superiority when it comes to one’s personality. The others theories in our text this week could be used to explain modern developments in personality, but this one seemed to fit the best. | <urn:uuid:d84ba865-956d-472f-9e5a-d56da3d4e5de> | CC-MAIN-2024-51 | https://homeworkhelp-experts.com/2023/08/17/respond-to-the-following-3-post-300-words-each/ | 2024-12-04T16:02:32Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066181697.67/warc/CC-MAIN-20241204141508-20241204171508-00200.warc.gz | en | 0.967178 | 2,540 | 2.796875 | 3 |
Protein is the queen of every diet. If the body does not receive enough of it, health will inevitably suffer the blow. However, there are many different opinions about how much protein is really necessary.
Most official nutritional organizations recommend a fairly modest consumption. The baseline data points to 0.8 grams of protein per kilogram of body weight (1).
This in turn means:
-56 grams per day for the standard sedentary man
-46 grams per day for the standard sedentary woman
Although this amount may be enough to prevent protein deficiency, studies show that it is far from sufficient to ensure optimal health.
But the ideal amount of protein for each individual can depend on many factors, including activity level, age, muscle mass, physical goals and overall health.
So how much protein is optimal and how do lifestyle factors play a role?
What is protein and why is it useful?
Proteins are the main building blocks of the body. They are part of muscles, tendons, organs and skin.
In addition, they are used to manufacture enzymes, hormones, neurotransmitters and various small molecules with important functions. Thus, without proteins, life as we know it would not be possible.
Proteins are made of smaller molecules called amino acids, which are joined together like beads on a necklace. The bound amino acids form long protein chains, which then fold into complex shapes.
Some of those amino acids can be produced by the body, while others must be incorporated through the diet. The latter are called “essential amino acids”.
The consumption of protein should not only have quantity, but also quality. Generally, animal proteins provide all the essential amino acids in the right range so that the body can use them all. It is logical, considering that animal tissues are similar to ours.
So, if products such as meat, fish, eggsor dairy are consumed every day, surely the protein supply is correct. But in diets that don’t include animal foods, the challenge of getting the ideal dose of protein and amino acids is greater.
Most people won’t need protein supplements, but they can be helpful for athletes and bodybuilders.
Summarizing: Protein is a structural molecule made up of amino acids, many of which cannot be produced naturally by the body. Animal foods are generally high in protein and essential amino acids.
Protein can help you lose weight (and keep you not gaining it)
To lose weight, you need to consume fewer calories than you burn. And consuming protein can help that process by speeding up the metabolic process that eliminates calories and reducing appetite. This is fully supported by scientific studies (2).
Protein intake hovering around 25-30% of total calories accelerates metabolism to 80-100 calories per day, compared to lower-protein diets (3, 4).
But probably the most important contribution of protein to weight loss is its ability to reduce appetite and cause a spontaneous reduction in calorie consumption. Protein satisfies more than fats and carbohydrates(5).
In a study of obese men, protein intake of 25 percent of daily calories increased feelings of fullness, halved the desire to eat fast food at night, and also reduced obsessive thoughts about food by 60 percent (6).
In another study, women who raised their protein intake by 30 percent ended up consuming 441 fewer calories per day. In addition, they lost about 5 kilos in 12 weeks just by adding more protein to their diet (7).
But protein can not only help you lose weight, but directly not gain it from the beginning.
In one study, a modest increase in protein, from 15% of calories to 18%, reduced by 50% the amount of fat recovered by individuals who had already lost it (8).
A high protein intake also helps preserve muscle mass, which burns a steady small amount of calories.
Thus, consuming more protein will make it easier to maintain any diet that helps you lose weight, whether high or low in carbohydrates.
A protein intake that is around 30% of the amount of calories can be optimal for weight loss. This would be around 150 grams per day in someone consuming a diet of 2000 calories a day.
In short: a protein intake that is around 30% of total calories seems to be optimal for weight loss. It accelerates metabolism and causes a spontaneous reduction in calorie consumption.
More protein results in greater muscle mass and physical strength
As with most body tissues, muscles are dynamic and constantly break down and regenerate. And to gain muscle mass, the body must synthesize more muscle protein than it loses.
In other words, a net positive balance of protein, sometimes called a nitrogen balance, is needed because protein is high in this chemical.
For this reason, people who want a lot of muscle should consume a greater amount of protein (and follow a weight-bearing regimen, of course) (9).
In addition, people who want to maintain the muscle mass you’ve already generated will also need to increase their protein intake while losing body fat, because this will prevent the muscle loss that usually accompanies weight-loss diets (10).
When talking about muscle mass, studies generally do not take into account the percentage of calories, but the daily grams of protein per unit of body weight. A common recommendation for gaining muscle is 2.2 grams of protein per kilogram.
Numerous studies have tried to determine the ideal amount of protein to gain muscle mass and have reached different conclusions.
Some studies showed that more than 0.8 grams per pound of weight has no benefit (11) while others showed that consuming just over one gram of protein per pound of weight works well (12).
And while it’s hard to give exact numbers because the results in studies are conflicting, 0.7 to one gram per pound of weight seems like a reasonable estimate.
If you have a high level of body fat, then it is a good idea to use both lean mass or goal weight instead of total weight, because it is mostly lean mass that determines how much protein is needed.
Summarizing: It is important to consume protein if you want to gain or maintain muscle mass. Many studies suggest that a consumption of 1.5-2.2 grams per kilo is sufficient.
Other circumstances that may raise the need for protein
Beyond muscle mass and physical goals, active people need more protein than sedentary people.
If you own a physically demanding job or routine that includes walking, running, swimming, or any form of exercise, then you will need more protein. Endurance athletes also need it in good quantity, around 1.2-1.4 grams per kilo (13).
Older people also have higher protein needs, up to 50% higher (14). This helps prevent osteoporosis and sarcopenia (reduction of muscle mass), very significant problems in old age.
And those recovering from any type of injury also need more protein(15).
Summarizing: Protein requirements are elevated in physically active individuals, older people, and individuals recovering from injuries.
Do proteins have any negative effects on health?
It has often been said that a high-protein diet can cause kidney problems and osteoporosis. However, none of this is supported by scientific studies.
Although protein restriction helps people with pre-existing kidney problems, protein does not cause kidney damage in healthy people (16).
In fact, higher protein intake lowers blood pressure and helps fight diabetes, two of the highest kidney risk factors(17).
And if protein actually has any negative effect on kidney function (which has never been proven) this is outweighed by the positive effects on risk factors.
Proteins have also been blamed for causing osteoporosis, which is strange considering that studies show that it can in fact prevent it(18).
Overall, then, there is no evidence that reasonably high protein intake has adverse effects in healthy people.
Summarizing: Proteins have no negative effect on kidney function in healthy people and studies show that it improves bone health.
How to introduce protein into the diet
The biggest sources of protein are meat, fish, eggs and dairy. All of them contain the amino acids that the body needs.
But the truth is that it is not really necessary to track the amount of protein that is consumed. In a healthy person trying to remain healthy, only consuming quality protein at most meals (along with nutritious vegetables) should maintain the optimal range.
What does “grams of protein” really mean?
When we talk about “grams of protein,” we are talking about the nutrient, not grams of a food that contains it. A usual serving of red meat weighs 226 grams, but contains 61 grams of protein. One egg weighs 46 grams and contains 6 grams of protein.
What about the standard person?
If you are at a healthy weight, do not lift weights and do not exercise too much, 0.8 or 1.3 grams of protein per kilo of weight is a reasonable consumption. This means:
-59-91 grams per day for an average man
-46-75 grams per day for an average woman
But since there’s no evidence of harm and there is significant evidence of benefit, it’s better for most people to aim for higher protein intake than reduced ones.

The sun is a powerful symbol of freedom, radiating warmth and energy to all that bask in its light.
Residential solar system installation allows individuals to take advantage of this natural source of power and independent living. By harnessing the rays of the sun, homeowners can enjoy clean and reliable electricity at an affordable cost.
This article will explore the benefits associated with residential solar system installation and consider some important factors related to this endeavor.
Residential solar system installation is an increasingly popular way for homeowners to reduce their energy costs and become more sustainable. Solar panels can be installed on rooftops, or in yards, depending on the space available and local regulations.
The main components of a residential solar system are photovoltaic (PV) modules which convert sunlight into electricity; inverters that allow electricity generated from solar panels to be used by appliances; mounting hardware such as racks and other support structures; wiring and cables connecting all parts of the system, and any required power conditioning equipment.
Installing a residential solar panel system typically begins with a site assessment, followed by electrical safety checks and permitting. Consultation services may also need to be obtained if there is uncertainty about the proper placement or orientation of PV modules.
Professional installers will then mount the array securely onto the roof or ground-mounted structure, connect it to an inverter, run wire connections between all components, and finally test the system before commissioning it. All components should comply with international safety standards for optimal operation.
After completing these steps, regular maintenance inspections should take place to ensure continued performance over time.
The sun emits a vast array of energy that can be used to power homes and businesses. Installing solar panels for residential use is becoming increasingly popular as people realize the potential savings on electricity bills and the positive environmental impact such installations have.
But before you make this investment, some key factors must be considered.
Firstly, it’s essential to understand your local regulations when installing home solar systems. Depending on where you live, the installation process may require approval from your local government or utility company.
Additionally, understanding the amount of usable space available on your roof will help determine how many solar modules you need in order to generate sufficient electricity for your home. Furthermore, assessing how much sunlight exposure your property receives can inform whether or not photovoltaic technology is suitable for generating enough energy for your needs.
In addition, budgeting for a system installation should factor in any financial incentives offered by state programs and federal tax credits that could reduce costs substantially. Adopting an environmentally friendly approach at home also requires researching different module types and their efficiency levels and selecting certified professionals specializing in solar panel installation services to ensure quality assurance and compliance with all necessary safety measures.
Considering these steps gives homeowners peace of mind knowing they have made an informed decision about investing in renewable energy solutions tailored specifically to meet their unique requirements.
Installing a residential solar system is an important decision that requires careful consideration. Before committing to installing such a system, homeowners should ask themselves several key questions. These include:
Answering these questions will help ensure that homeowners have the necessary information to make informed decisions about whether installing a residential solar system is the right choice.
Researching local and state regulations on renewable energy will also provide valuable insight into potential issues related to roof access and permission and any restrictions on what can be installed where.
Additionally, reaching out to professional contractors with experience in the field is another worthwhile step before beginning installation work. Doing so helps guarantee quality results while minimizing risks associated with inexperienced workers or companies. It also allows homeowners to compare quotes and find competitive prices for service and installation costs.
Considering all this information is essential when deciding if investing in a residential solar system is right for you. Understanding your current energy consumption habits, researching applicable incentives and laws, and consulting with professionals are all critical steps toward achieving successful installation outcomes while avoiding costly errors down the road.
The sun is a source of infinite energy, allowing us to gain independence from traditional electricity sources. Installing solar panels on one’s home has become an increasingly popular way to tap into this renewable resource and provide clean power for households. But before installing such a system, ensuring that your house suits these panels is important.
Assessing suitability requires considering several factors; firstly, enough space on the roof or ground should be available to accommodate the required number of panels.
Additionally, the surface needs to have adequate structural integrity so as not to cause any damage when installing them.
Furthermore, the roof’s orientation must face southwards towards direct sunlight to maximize efficiency and reduce shading interference from nearby objects like trees and buildings.
Finally, checking local regulations regarding installations may also prove necessary since some cities may have specific rules about residential solar systems set by government ordinance.
By ensuring all these criteria are met before installation, homeowners can rest assured knowing they are making an investment in their future that will pay financial and environmental dividends.
The first step to determining whether your house is suitable for solar panel installation is assessing the location, orientation, and amount of sunlight it receives. These factors can influence the efficiency of a system, so it’s important to consider them before installation.
When considering a residential solar panel installation, budget is one of the most important considerations. This includes upfront costs associated with purchasing and installing hardware and long-term savings on energy bills.
It’s critical to carefully research different systems to make an informed decision about which type will best meet your needs. Additionally, understanding applicable tax credits or other incentives may help you save money by offsetting some of the initial cost.
Ultimately, finding an option that fits within your budget while also providing reliable performance and lasting value should be a priority when choosing a solar system for your home.
The question of how many solar panels it takes to power a house is one that has intrigued the minds of environmentalists and those interested in renewable energy for some time.
To unravel this mystery, let us take an illuminating journey into the world of residential solar systems.
When considering what size system you need, there are several factors to consider, such as roof space available, local climate conditions, and daily electricity usage.
Generally speaking, a typical household will require anywhere from 10-15 solar panels to generate enough energy to cover their electricity needs. However, sometimes more or less might be needed depending on your particular situation.
Solar panel systems also come with inverters that convert the direct current (DC) generated by the panels into useable alternating current (AC). The number of these required can vary based on how much electricity you want to produce and how quickly you want to install them.
Although it may seem complicated at first, determining exactly how many solar panels are necessary for powering your home does not have to be a daunting task. Once you understand the basics of system sizing and installation requirements, you’ll be well on your way to enjoying all the benefits that come with having a clean source of renewable energy!
With careful planning and expert advice, tapping into sustainable sources like solar power can provide independence from rising utility bills while helping reduce our environmental impact – creating unlimited opportunities for freedom along the way.
When installing a residential solar system, calculating how many solar panels you need is the first step. In order to do this, several factors should be taken into consideration:
It’s important to consider current and future energy needs when determining exactly how many panels you require; doing so will ensure maximum savings over time while allowing homeowners to take advantage of any available tax credits or rebates.
Additionally, speaking with a qualified installer can help provide detailed information about local regulations and incentive programs that might further reduce costs associated with your project. With careful planning, proper calculations, and expert guidance, transitioning to renewable energy has never been easier!
Installing a residential solar system can be an immensely rewarding experience for the homeowner, providing freedom from energy bills and reducing their carbon footprint. To reach this goal, however, obtaining the appropriate permit from the local government is necessary. Depending on where one lives, the requirements may vary slightly; nevertheless, most jurisdictions follow these key steps:
Step | Description |
Research | Investigate your jurisdiction’s specific regulations and codes for installing solar systems. Check with your utility company, too, as they might have additional special requirements. |
Application Submission | Submit all required documents, such as building permits or other forms of approval, along with fee payments according to the guidelines of your local government. This process may take some time, so plan ahead accordingly! |
Inspection & Approval | Inspections will occur before or after installation begins to ensure that everything meets safety requirements and electrical code standards. Once approved, you’ll receive final authorization allowing you to officially operate your new solar power system. |
The feeling of accomplishment when a residential solar system is successfully installed cannot be understated – imagine having access to clean, renewable electricity while saving money at the same time! Obtaining relevant permits may seem daunting, but following the basic steps above can make it easier than expected. Ultimately, taking the initiative to go through this process leads towards greater autonomy and independence from traditional methods of electricity generation.
Securing the necessary permits is a critical step in installing residential solar systems, but it’s just one part of the process. Once all permits have been obtained, homeowners can compare and choose an installer for their home’s solar system.
Several factors should be taken into consideration when selecting an installer:
When looking for a competent contractor to handle your installation project, research thoroughly and ensure you get multiple quotes before deciding.
Check online reviews, ask others who have had similar projects done in their homes, and talk directly to contractors about their experience with installations like yours.
It may take some time up-front investing in researching possible candidates, but doing so will help guarantee satisfaction with your final selection.
Finding a reliable solar installer in your area is essential to ensure the success of any residential solar system installation. Solar installers provide professional services that help homeowners make informed decisions about which solar energy system best suits their needs and budget.

Comparing bids between different companies will allow you to make an informed decision on who can provide you with the best service at the most reasonable price.
The second step is for the installer to perform a site assessment. This involves looking over the property where the panels are to be installed – taking into account things such as orientation, roof pitch, shading issues, etc.
Additionally, it also includes making sure all permits are filed correctly and any other paperwork needed for local/state regulations is taken care of before starting work on the installation. Taking these steps ensures that homeowners have access to clean energy solutions while also avoiding potential complications due to incorrect paperwork or positioning of their solar array.
By exercising due diligence and researching thoroughly ahead of time, homeowners can confidently move forward in their journey toward freedom through renewable energy sources like solar power.
Choosing the right installer and utility for a residential solar system installation is an important decision to make. It requires researching multiple companies before selecting the best option that suits your needs.
The process of working with an installer and utility involves four main steps:
From start to finish, working with an experienced installer and reliable utility can help you reap maximum benefits from investing in a residential solar system. Understanding these components upfront prevents costly mistakes while ensuring seamless operation once everything is up and running.
With careful planning, homeowners can take advantage of clean energy sources while achieving long-term financial savings.
The installation of a residential solar system can be a great way to reduce energy costs in the long term and benefit from financial incentives.
The cost of such an installation will vary depending on various factors. Still, it is important to consider that the benefits of having a solar system far outweigh any initial expenditure.
Solar systems are relatively low maintenance, with only occasional inspections required. Most modern systems have expected lifespans between 15 and 25 years, so they provide lasting value for money.
As well as saving money on monthly electricity bills, there may also be tax credits or other financial incentives available at both federal and state levels, which further increase their appeal.
All considered, investing in a residential solar system will likely prove beneficial in many ways.
The solar system installation costs vary, depending on the size and type of equipment being installed. Generally speaking, such an installation tends to be expensive because it requires specialized labor and materials.
However, there are several incentives available that can help reduce the overall expense. These range from state or federal grants to tax credits for homeowners who go green with their energy sources.
With these in mind, residential solar system installations may even end up saving money in the long run through reduced electricity bills and other benefits.
A solar system is a shining example of an investment that pays off in the long term.
It gives homeowners the freedom to save money while also allowing them to reduce their environmental footprint.
While there may be some initial costs associated with installation, these are quickly forgotten when taking into account the substantial savings on energy bills over time.
Solar systems provide clean and renewable energy, which can significantly lower your electricity bills by reducing the amount of power you need from other sources – not only providing financial benefits but peace of mind as well.
The maintenance of a solar system is an important aspect to consider when investing in this renewable energy source.
Solar systems require regular cleaning and inspection by qualified technicians, typically every three to five years.
Cleaning involves removing dirt, dust, and debris from the panels. At the same time, inspections may include checking for broken or damaged components, examining electrical connections, and ensuring proper operation of inverters and other related equipment.
This type of maintenance ensures that your solar system continues to run efficiently over its lifetime, providing you with long-term benefits such as lower electricity bills and reduced carbon emissions.
Satirically speaking, residential solar systems can last forever – at least, that’s what the salespeople will tell you!
In reality, though, when comprehensively maintained and inspected regularly, these types of solar energy systems typically have an estimated life span ranging from 25 to 30 years. This is due to their reliable design and construction methods which ensure they are able to withstand harsh weather conditions.
Additionally, with a wide range of components available on the market today, homeowners can customize their system according to their specific needs to maximize its longevity and efficiency.
The installation of a residential solar system may be eligible for various tax credits and other financial incentives.
In the United States, such incentives may include a federal investment tax credit (ITC), which can provide up to 30 percent back on the cost of installing a solar system.
Additionally, many states offer their own incentive programs for residents who choose to install an energy-efficient solar panel system or alternative renewable energy sources within their homes.
These incentives vary from state to state but often cover some percentage of the total installation cost as well as any associated fees with obtaining permits and connecting the system to local power grids.

Water filters play a crucial role in providing us with clean, safe drinking water. Yet, not many people know the mechanisms at play that turn murky, contaminated water into a healthy drink.
Different types of filters rely on different methods to purify water.
Some use activated carbon, trapping pollutants like chemicals and dirt. Others use reverse osmosis, pushing water through tight membranes to remove unwanted particles. There are even filters using ultraviolet light to kill bacteria and viruses.
But how exactly do these systems differentiate between what to keep and what to remove, and more importantly, how do they maintain the essential minerals your body needs?
Let’s explore the science behind water filtration, and you might discover the perfect solution for your water quality concerns.
- Water filters remove impurities through porous materials that act as physical barriers.
- Different filters target specific contaminants like sediment, heavy metals, chlorine, and organic compounds.
- Investing in a water filter offers benefits beyond clean drinking water, including healthier skin and hair, reduced plumbing repair costs, and a lower environmental impact.
The Basics of Water Filtration
The mechanics of a water filter involve a sophisticated filtration process designed to tackle contaminants that range from sediment and heavy metals to chlorine, VOCs (Volatile Organic Compounds), and TDS (Total Dissolved Solids).
This process is crucial for guaranteeing the safety and palatability of your drinking water.
At the core of this filtration system is the movement of water through a porous material, a method that effectively separates harmful contaminants from the water.
The specifics of this process vary significantly among the different types of filters available. Each type of filter is engineered to target specific contaminants, leveraging the unique properties of its filtering medium.
For instance, while one filter might utilize activated carbon to remove chlorine and improve taste and odor, another might employ reverse osmosis membranes to reduce TDS levels.
This diversity in filtration technology underscores the importance of understanding the specific contaminant removal capabilities of various water filters. It’s especially important when selecting a system for your home to make sure your drinking water is clean and safe.
Common Types of Water Filters
We live in an era where technological advancements hit the market one after another.
Water filtration technology is also highly advanced and diverse, each type addressing specific impurities and water quality issues.
Mechanical water filters remove particulates through a physical barrier, whereas reverse osmosis systems force water through a semipermeable membrane, stripping it of a wide array of contaminants.
Activated carbon filters, on the other hand, adsorb organic compounds and chlorine, improving taste and odor.
Water softeners and ultrafiltration systems target water hardness and microbial pathogens, respectively.
Mechanical Water Filters
Sediment and ceramic filters are the primary types of mechanical water filters.
- Sediment filters use layers of mesh to trap and remove particulate matter, ensuring clarity and reducing potential clogs.
- Ceramic filters rely on the porosity of ceramic material to catch smaller particles, offering an additional layer of purification by potentially trapping microorganisms.
To effectively safeguard both sophisticated water treatment systems and household plumbing, sediment filters play an essential role in removing particulate matter from water.
These filters, integral to whole-house filtration, capture dirt and sediment, preventing them from clogging pipes and appliances.
Ceramic filters, with pores just 0.5 microns across, effectively remove particles larger than 0.0005 millimeters, including sediment and about 99% of pathogenic bacteria.
Configured in multistage designs, they often incorporate an activated carbon filter and ion exchange resin, enhancing water filtration by also eliminating chlorine, VOCs, and heavy metals.
Reverse Osmosis Systems
While reverse osmosis systems are highly sought after for their ability to produce exceptionally pure water, it’s crucial to understand the intricacies of their multi-stage filtration process.
These systems incorporate a holistic approach, beginning with a sediment filter to remove large particles, followed by a carbon filter that captures smaller contaminants.
The reverse osmosis membrane play a key role here. It’s a selective barrier that allows only water molecules to pass through, rejecting dissolved salts, bacteria, and chemicals.
Designed for point-of-use applications, these systems are typically installed under a sink to provide purified water at a single faucet.
Nonetheless, it’s important to note the necessity of a water softener in hard water areas to prevent mineral buildup on the membrane.
Despite their benefits, RO systems’ efficiency is often critiqued due to significant wastewater production, generating about five gallons of waste for every gallon of filtered water.
Activated Carbon Filters
Activated carbon filters, found in a variety of household water treatment systems, leverage adsorption to efficiently capture contaminants, delivering cleaner, taste-enhanced water directly to your tap.
These filters, integral to both refrigerator and water pitcher filters, excel at eliminating undesirable elements from municipal water, such as chlorine and chloramine, greatly improving water’s taste and odor.
Beyond these, activated carbon adeptly removes harmful substances like trihalomethanes, mercury, pesticides, herbicides. It can even remove certain heavy metals and microorganisms, depending on the filter’s certification.
Filtration systems, including reverse osmosis units, invariably incorporate at least one activated carbon stage, underscoring its pivotal role in purifying water.
Water softeners are systems specifically designed to remove water-hardening minerals through ion exchange. These ion exchange systems work by swapping sodium ions for the calcium and magnesium ions responsible for water hardness.
The process hinges on plastic resin beads, which are negatively charged and attract the positively charged minerals as water flows through them.
This water softening technique not only safeguards your home’s plumbing from limescale buildup but also extends the lifespan of appliances by preventing the damage hard water can cause.
NOTE: Incorporating a water softener before a reverse osmosis (RO) system is essential. This prevents the RO membrane from clogging with minerals, ensuring the filtration process remains efficient and effective.
Unlike a reverse osmosis system, ultrafiltration utilizes a .02-micron hollow fiber membrane, adept at removing nearly all contaminants except for dissolved minerals.
This precision in contaminants removal guarantees your water retains those essential minerals, making ultrafiltration systems a prime choice for those valuing mineral content.
On top of that, these systems don’t generate wastewater. It is a significant advantage for households in areas facing water restrictions.
Typically installed under the kitchen sink, ultrafiltration systems offer a practical solution for obtaining clean drinking and cooking water without the drawbacks associated with reverse osmosis systems, such as mineral depletion and water wastage.
Water Purification Systems
Water distillers and UV water purifiers represent innovative solutions within the domain of water purification systems, distinct from traditional filtration methods.
- Water distillers operate by boiling water and then condensing the steam, removing contaminants.
- UV purifiers use ultraviolet light to kill bacteria and viruses without altering the water’s chemistry.
Among the water purification systems, water distillers consistently provide the highest purity level. This level of effectiveness makes them indispensable for critical applications in laboratories, hospitals, and automotive cooling systems.
This water treatment method mimics the hydrologic cycle, heating water into vapor to separate it from contaminants.
It’s a slow process but guarantees that you’re getting the purest water, free from any impurities left in the boiling chamber.
UV Water Purifiers
Using specific wavelengths of UV light, UV water purifiers effectively deactivate microorganisms in water. Because of that, they are an excellent option for homes relying on well water or facing boil water advisories.
These systems depend on sediment filtration to prevent blockage and maintain effectiveness.
Primarily, they serve as the final step in point-of-entry filtration, or alongside other filters, enhancing point-of-use drinking water safety by targeting bacteria, viruses, and parasites.
Should You Get a Water Filter?
Deciding whether to invest in a water filter requires careful analysis of your water quality and consumption habits.
A reliable water filter provides more benefits than just clean water to drink. It also greatly contributes to maintaining healthy hair, reducing plumbing repair costs, and minimizing the environmental impact of bottled water consumption.
Here’s a detailed breakdown:
Benefit | Description |
Clean Tasting Water | Ensures safe drinking water, free from harmful chemicals or metals. |
Glowing, Healthy Skin | Eliminates deposits that clog pores, promoting clear skin. |
Healthy Hair | Prevents chemicals from affecting hair and scalp health. |
Lower Plumbing Repair Costs | Reduces damage to plumbing systems caused by minerals and chemicals. |
Environmental Impact | Decreases reliance on non-biodegradable plastic bottles, reducing pollution. |
How Much Do Water Filters Cost?
The cost of water filters can vary greatly based on the system type and installation location.
Point-of-entry filters, designed to treat water for your entire home, demand a higher expenditure due to their thorough filtration capabilities and the volume of water they can process.
Conversely, point-of-use systems, which treat water at a single source, are typically less expensive but vary widely in price depending on the specific technology employed.
Here’s a breakdown of the costs you might encounter:
- Point-of-Entry Systems: These whole-house systems can range from $800 for basic sediment and carbon filters to up to $3,000 for advanced UV filtration systems, including prefiltration. The average cost also encompasses water softeners, falling between $1,500 and $2,300, with installation costs factored in.
- Point-of-Use Systems: On the smaller scale, these systems can be as affordable as $10 for a simple water pitcher filter to around $1,000 for a more sophisticated UV system. The price includes installation and spans various technologies like reverse osmosis and ultrafiltration systems, which generally cost between $200 and $500.
It’s important to account for installation expenses, which are included in the average cost estimates for both point-of-entry and point-of-use systems presented above. These costs can have a significant impact on the total investment in your water filtration solution.
Maintenance and Replacement Tips
To guarantee your water filtration system operates efficiently, it’s important to adhere to regular maintenance and timely replacement of key components.
Different types of water filters have varying maintenance requirements and replacement schedules.
Firstly, inspect replacement filters based on the manufacturer’s guidance, which typically outlines the volume of water they can purify before their efficiency diminishes.
For instance, sediment filters, which trap physical particles, may need more frequent changes compared to chemical absorbers, depending on your water’s quality.
Monitoring the performance of your water filter systems is also crucial. A noticeable decrease in water flow or a change in taste or odor indicates it’s time to examine your filtration media and possibly replace it.
Moreover, it’s advisable to keep a log of maintenance and replacement activities. This record-keeping won’t only help you track the system’s upkeep but also identify patterns that might necessitate adjustments in your maintenance plan.
Selecting the right water filter hinges on understanding your specific filtration needs.
Mechanical, reverse osmosis, activated carbon, water softeners, and ultrafiltration systems each offer distinct contaminant removal capabilities.
Before making the final decision, analyze water quality and contaminants present to choose an effective solution.
Thoroughly weighing costs against benefits and maintenance requirements will guide you to the most suitable water filtration system for your needs.

Important information to know about your baby’s 4th through 9th months
Important information to know about your baby’s 4th through 9th months
This tends to be a time when babies get their first colds and other illnesses, particularly during winter months. Most are not dangerous at all. The best clue is in the eyes – a baby who looks well usually is, while a baby who is really ill will tell you with the look in his eyes.
Prevention is best. All babies should see the pediatrician at about 4, 6, and 9 months of age. These visits are not just for shots, but are times when we screen for a variety of subtle problems and are a good opportunity for you to learn more about your baby.
At 4 and 6 months the baby will receive vaccines again. Mild soreness at the site of the vaccines is likely. Giving Acetaminophen every four hours for a day may prevent or minimize this. The benefits of giving these vaccines FAR outweigh the risks involved. If you want to know more about this, see our more detailed vaccine handouts or ask.
Fever is the body’s normal response to any kind of illness and actually HELPS you get better. It is not dangerous and cannot hurt your child. Furthermore, neither the presence nor the height of a fever has any correlation with how dangerous the illness causing it is. Minor viruses often cause very high fevers, while some deadly illnesses cause little fever at all. Thus, it is the OTHER symptoms of illness we are most interested in when evaluating your child.
Fever is uncomfortable, and this is why we treat it. Use Acetaminophen (Tylenol, many other brands) infant drops according to the instructions in our Acute Illness Guide. Never use aspirin in children. Sponge baths are also unwise – they actually raise the temperature deep inside the body rapidly while cooling only the surface. Getting the child with a fever to drink plenty of fluids is important for many reasons, and will help get the fever down as well.
Do not use nonprescription “over-the-counter” medications for coughs, colds, diarrhea, etc. unless directed by a physician. In general, the side effects far outweigh the minimal benefits in this age group.
Teething can start anytime from 3 – 15 months, and is somewhat painful. It can cause drooling, a runny nose, poor sleep, irritability, and even pulling at the ears. It does not cause fever, vomiting, diarrhea, or a rash however. It is best to avoid “rub on” teething medications – babies can overdose on these. Use Acetaminophen for the pain and give the baby something to chew on to speed up the process. A bagel often works better than conventional teething rings, especially beyond 6-7 months age.
Even a minor illness that doesn’t seem be getting better after 7-10 days should be seen by the doctor.
Babies need FULL TIME protection!
A car seat should face the rear of the car until the child is 2 years of age.
Test baby’s highchair before you buy it. The base should be wide and stable so it will not fall over if bumped by another person or if the baby tries to crawl out. NEVER leave the baby alone in a high chair.
Don’t put the baby in a walker. They lead to falls, poisonings, and choking. Swings, playpens, and “Johnny jumpers” are all much safer.
Now is the time to “Childproof” your home. Be sure all small objects that the baby could choke on are both out of reach and out of sight (e.g. buttons, coins, bottle caps, pins, nuts, raisins, older child’s toys). Put “shock stops” in all unused electrical outlets and move all cleaning fluids, medicines, etc. to high cabinets. Don’t rely on so-called “Childproof” cabinet latches – they don’t work. Make sure your water heater is set not to exceed 120ºF.
Never turn your back on a baby in a bath, on a changing table or on a bed EVEN FOR A SECOND!
Second Hand Smoke is very dangerous. Even if you or a family member smokes outside- the smoke is brought in on your clothing. Please consider quitting
Introduce solids anytime between 4 and 6 months. Usually your baby will tell you he is ready by watching you eat with intense interest and by being somewhat less satisfied after a breast or bottle feeding.
Start slowly – at first this is a new experience. Your baby will need time to learn. When the baby starts to spit or push the spoon away – stop, don’t push it. There will be plenty of interest later.
Initially feed your baby one solid meal per day. Space it in between breast or bottle feedings so that you are not giving milk right after or right before; that way the baby is not full, nor are you “rewarding” him or her for stopping by giving milk at the end of the meal.
Start any type of single grain cereal mixed with formula, breastmilk, or water. After that start with fruits & vegetables -the order in which new foods are introduced is at your discretion – Have Fun and try a variety of flavors! You can introduce a new food every 3-5 days, never more than one at a time so that if one causes a problem you’ll know which it was.
When your baby is ready – move from 1 to 2 meals per day (usually around 6 months), then from 2 to 3 meals per day. Protein should be introduced at 6 months (meat, eggs, nuts, tofu & beans). This is also a great time to introduce a sippy cup of water. At first this is likely just for practice – they will hold it, throw it and drop it on the ground! Soon they will have the hang of it and be ready to transition fully from a bottle to a sippy cup between 9 months- 1 year.
Babies under one year of age should not consume Honey. Otherwise there is no need to avoid any foods that do not pose a choking hazard. There is NO evidence to suggest the delay of solid in general OR of specific foods (eggs, wheat etc…) decreases the risk of developing allergies, eczema or asthma in the future. And in fact may INCREASE your child’s risk.
Continue using breastmilk or an iron-fortified formula as the main drink throughout this age group. Both have many distinct advantages over regular cow’s milk that your baby still deserves the benefit of. Also, avoid juice. Even “natural” juice is little more than sugar and water, your baby needs it about as much as you need beer.
The first exposure to a highly allergenic food should occur in the home (Eggs, nuts, wheat and fish). Benadryl is a useful medication to have in your home in the event of an allergic reaction.
Starting at 9 months you may begin offering small amounts of whole milk (ideally in a sippy cup) – your child should be fully transitioned from formula to whole milk by 1 year of age. Toddler and transitional formulas are nutritionally and developmentally unnecessary.
Babies (especially those who are breast-fed) should be taking a Vitamin D supplement (D-vi-sol). Check to be sure there is Fluoride in your water. Most but not all Massachusetts communities have it; bottled water, Methuen and most NH towns do not. If it’s not in the water you’re using ask your provider or dentist for recommendations.
By four months your baby is a very capable person! He or she is vocalizing constantly, rolling over, reaching and grasping objects, and clearly differentiating you from strangers. Everything goes in the mouth, as this is the most discriminating sense organ at this age. Weight will soon be double what it was at birth!
Around 6 months your baby will sit without support and pass objects from one hand to another. Soon consonant sounds such as ba-ba or ma-ma will be added to vocalizations. Often the latter starts with tongue thrusting games such as blowing bubbles or “raspberries”. By 9 months your repeated expressions of delight at hearing “ma-ma” or “da-da” will be starting to teach the baby that words have meaning and that you are called by that name!
By 9 months babies are also starting to become much more mobile. They may crawl or creep (although many children skip this), or they may be beginning to “cruise” – pulling themselves up on furniture and getting around by hanging on. Appropriate toys for this age group include any brightly colored, noise-making objects small enough to be grasped by little hands yet big enough not to present a choking hazard. You want to expose the baby to a wide variety of shapes, colors, sounds, and textures.
Also by 9 months certain key signs of normal thinking abilities should start to appear. The most importance of these are “joint attention” and “object permanence”. Joint attention is when the baby actively “shares” his or her attention to something fun or interesting with someone else – usually a parent or sibling. They might point and laugh, and look back and forth from the object to the other person to gauge the other person’s response. Object permanence means that just because something is out of sight, it’s not gone. Children who have object permanence will understand that a hidden object can be retrieved, and will start to enjoy the game of “peek-a-boo”.
Very limited or no screen time is recommended for children under two years of age. Screen time refers to television, computer, video games, tablets and phones.
Don’t fall into the trap!
This is an important age for establishing normal sleep patterns. While holding or rocking your child to sleep was fine for the first few months, you need to try hard to get away from that now.
Establish a bedtime “ritual” for when you are going to put the baby down, and then be sure the baby falls asleep IN BED, not in your arms. There should be no bottle involved. This way, the baby can learn to go to sleep independently, without you or the bottle to help. When brief awakenings, which are normal, occur during the night the baby will then not need you to “go back down”. Both of you will sleep better as a result. Sometimes some crying is necessary to get to this point. Talk to your provider about a more specific sleep plan if there is trouble in this area
Sunlight can be a big threat to healthy skin. Always use a sunscreen on exposed baby’s skin – even in spring and fall when you might not think of it. Select a PABA-free preparation with SPF 15 – 30. Or keep baby clothed in loose, light but long clothing and a hat.
Ointment is better than powder for protecting against diaper rash, but it really doesn’t matter which ointment you use. Powders (all types) can also be dangerous if accidentally inhaled. Soap is very drying to the skin, even “baby soap”. Dove is the mildest and probably the best. Avoid deodorant soaps.
A baby needs happy, satisfied parents.
Are there things you enjoy but haven’t done since baby arrived? Get back to them now! Set aside time to be with your partner by getting a babysitter. Spend some special time alone with the baby’s older siblings. Maintain your hobbies, interests, career, etc.
It is normal and very common for parents to feel depressed, anxious, and overwhelmed. It may seem hard to cope with a screaming baby and you may even feel as if you’re about to lose control. Help is available. Call us or call Parental Stress Line at 1-800-882-1520
Do you feel safe at home? You are not alone, to speak to someone in confidence call National Domestic Violence Hotline (800) 799-SAFE.

GCI TECH NOTES ©
David Constans and David Gossman
Hazardous waste fuel has been used as an alternate or supplemental fuel in cement kilns since 1980. Since 1992, with the promulgation of the BIF regulation, this activity has become heavily regulated. Additionally, partly because of BIF and other hazardous waste regulations, the growth of hazardous waste volumes suitable for use in HWF have stopped and, in some respects, the supplies are shrinking. This is to be expected. Indeed, this was one of the stated goals of these regulations. However, the driving force behind the desirability of alternate fuels to fire cement kilns has not abated. That is, the desire to reduce total fuel costs through substitution of waste-derived fuels for the normal fossil fuels, primarily coal, used in these facilities. Consequently, there is renewed interest in the use of non-hazardous waste fuels. One of the most readily useable and highest heat content non-hazardous wastes is used tires. This Tech Notes discusses the use of tire derived fuel (TDF) in cement kilns. The various forms of TDF, how it is utilized in the different clinker production processes, the impact on product quality, and stack emissions from utilizing TDF.
Bits, Pieces or Whole Tires
TDF can be provided in a number of forms. The tires can be ground into "crumb". There are a number of advantages to utilizing this form. 1) The steel in the bead and radial bands can be removed via air classification, 2) The crumb can then be blown in with powdered coal fuel directly substituting for the powdered coal, 3) The transportation storage and management of the crumb is very similar to managing coal fines, both the good and the bad aspects of such management. There are disadvantages, or more properly unnecessary advantages, for cement kilns utilizing crumb TDF. The removal of the steel is unnecessary since cement kilns have a need for iron in its process. Producing the crumb is quite expensive, likely making the crumb as costly as the coal or coke it is replacing.
Tire "chips" of varying size are routinely utilized as cement kiln fuel. These chips range in size from 2 cm x 2 cm up to 15 cm x 15 cm squares. A variation on this is a "quartering" of the tires. In all cases, the transportation, storage and management is essentially the same. Transportation is via dump truck. Storage is generally in an open air pile similar to storage of coal or limestone. The feeding of the chips into the kiln is via a conveyor fed from a hopper. A front end loader is used to load the hopper from the storage pile.
The use of tire chips has a couple of advantages. The feed rate can be continuous and carefully regulated. Also, there is very little manual labor involved in handling chips versus whole tires. There are, however, a couple disadvantages. Like the tire "crumb", producing chips from whole tires is still expensive. Certainly not as costly as the production of crumb, but often half the cost of acquiring and delivering the TDF. The wire in the bead and radial belts do not shear smoothly when the tires are chipped. Consequently, the chips are ragged with these wires hooking onto everything they come in contact with; the front-end loader, the trucks, and other vehicles passing near the storage areas. In short, the chips migrate throughout the facility. One facility utilizing tire chips, after several months of use, plugged their raw mill with migrating chips. This necessitated a shut down and time consuming removal of the chips from the screen in the mill.
The use of whole tires as kiln fuel is common in the cement kiln industry. In this case, truck loads of whole tires, usually enclosed vans, are delivered to the end of a conveyor. Tires are manually unloaded from the truck onto the conveyor. The conveyor feeds the tires to a mechanism that inserts one tire at a time into the kiln at specified time intervals. The advantage of utilizing whole tires is that there is no processing costs in addition to the acquisition costs. Also, unlike tire chips, the whole tires do not migrate throughout the facility. Nor, like the crumb, are they subject to possible "dust fires". Transportation, storage and management of whole tires requires more logistical care and more manual labor than the management of the other TDF forms. Obviously, piles of whole tires are to be avoided. No one wants a tire pile fire. The most reasonable solution is to have the tires delivered, stacked in trucks. Multiple trucks may be on-site waiting to be unloaded onto the conveyor. Handling whole tires requires manual labor as such an activity is difficult to automate.
Input of the Tire into the Kiln
For the purpose of utilizing tires, there are two cement processes; long wet/long dry process kilns, or preheater/precalciner process kilns.
Long wet or long dry kilns can utilize tires in two ways. Tire crumb and smaller chipped tires may be blown in with the powdered coal or through a separate feed system. Whole tires can be injected mid-kiln through a Cadence gate attached to the wall of the kiln. The whole tire is placed in a scoop attached to the gate as it passes by a platform. As the gate rotates to the top of the kiln, the gate opens and the tire drops into the kiln. The maximum feed rate of the tires is generally limited to one tire per revolution. Although it is possible to install a gate that could insert two tires at a time, this is not recommended for reasons to be discussed later. Another possibility is a second gate on the opposite side of the kiln. Cadence Environmental Energy, Inc. has a patent on this technology and actively markets it world-wide. also, Tire Management Inc. has patented feed systems which are frequently used with a Cadence gate. Theoretically, it is possible to insert tire chips into the kiln utilizing this method. However, as noted above regarding tire chips, the hooking wires will create a feed problem both in the feeding of the chips into the scoop and the passing of the chips through the gate since neither of the locations can be "force fed" and depend totally on gravity as the motive force. The installation and especially the subsequent maintenance of the gate and its attached scoop can be quite costly and may require frequent outages. Additionally, the rush of cold air that enters the kiln with each opening of the gate negatively affects the efficiency of the kiln. This, however, is the only method of utilizing whole tires in long wet or long dry kilns.
It is easier to utilize TDF in preheater and/or precalciner kilns. Certainly crumb and small chips may be utilized as a direct substitute for powdered coal as in long wet and long dry process. The preheater/ precalciner process, however, allow the injection of whole or chip tires into the kiln quite simply through a chute down on to the kiln feed as it enters the kiln from the last stage of the preheater/precalciner. Whole tires or tire chips can be fed to a double gated chute into the duct between the kiln and the kiln feed discharge of the last stage. With the outer gate closed, the inner gate opens and drops the tire or the chips directly into the kiln feed or into a chute which drops the tire or chips into the feed. Again, such a "gravity system" may have problems with chips due to the hooking wires. However, this system is excellent for the whole tires (or for tire quarters). The timing of the opening/closing of the air lock can be set to optimize the input rate of the tires to minimize emissions impacts. (This is discussed in some detail below.)
Tire chips can be continuously fed into the preheater/precalciner kiln by feeding the chips into the duct and onto the kiln feed through a rotary valve or short screw. The screw has certain advantages over the rotary valve as the hooking wires of the tire chips will pass more easily through the screw. The feed rate of the chips can be regulated by the speed of the rotary valve or the screw.
The Effect of TDF on Product Quality and Stack Emissions
TDF is a very high quality fuel having about 13,000 to 15,000 BTU per pound, (7200 to 8300 kcal/kg), about the same as a superior quality coal. TDF typically has 0.5-2.0% sulfur, this is less than or equal to most coals and coke. The hydrocarbons that make up the rubber in the TDF are no more complex or difficult to destroy than those present in coal. The steel in the bead and the radial belts constitute about 12% by weight. The cement chemist must take this into account when he formulates his raw feed mix. TDF may have metals such as lead, cadmium and zinc. While this should not be a problem for most kilns, an experienced chemist should evaluate the concentrations of these and other metals in the raw feed, clinker and cement kiln dust to ensure the additional metals added with the TDF will not become a problem.
TDF fed at a rate that does not compromise metals input/output balances has no effect on clinker quality. Stack emissions of CO, however, may be affected due to the manner in which the tires are fed to the kiln. A uniform feed rate of crumb or chips will allow the operator to increase the kiln exit oxygen, or rather allow the operator to maintain the desired kiln exit oxygen concentration and/or the kiln exit CO concentration. However, the insertion of whole tires at one to two minute intervals will often produce a CO spike and/or an oxygen dip in the kiln exit gases. This can be compensated for by increasing the interval between tire insertion and/or by increasing the normal kiln exit oxygen by ½ to two percentage points. Some plants may also experience changes in SOX and/or NOX levels depending on where and when the TDF is burned, and changes in O2 levels.
It is estimated that there are 36 cement plants utilizing tire derived fuel each year in the United States. Both whole tires and tire chips are utilized as fuel with essentially similar results. | <urn:uuid:ae2d702a-8cf6-4b3f-a8a0-8f003cdd78b7> | CC-MAIN-2024-51 | https://www.gcisolutions.com/library/gci_tech_notes/gcitn199709.html | 2024-12-04T15:17:05Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066181697.67/warc/CC-MAIN-20241204141508-20241204171508-00200.warc.gz | en | 0.952981 | 2,154 | 2.703125 | 3 |
Bringing a new pet into a multi-species household can be daunting. Cats and dogs have vastly different needs, so ensuring everyone gets along requires insight and effort.
This guide cuts through the confusion with practical tips from veterinarians and animal behaviorists. You’ll learn how to introduce pets properly, set up a harmonious environment, interpret body language, and handle conflicts. With the proper techniques, even pets with big personality differences can coexist contentedly.
Here, you will find everything you need to help foster understanding between felines and canines.
Understanding Cat Behavior
Cats exhibit behavior that may seem perplexing, yet comprehending key feline traits provides critical insights for cohabitating successfully with dogs. As certified feline behaviorists emphasize, observing subtle nuances in your cat’s conduct unlocks the secrets behind crafting household harmony.
Territorialism and Marking
A cat’s primal territorial instinct induces scent-marking to define boundaries. They spread pheromones that proclaim ownership by rubbing against furniture or spraying urine. This can spark conflicts when dogs infringe on their zone.
Experts advise designating separate spaces catering to each pet’s needs. Place multiple litter boxes in quiet, secluded areas and absorbing pads on various territory edges. Eventually, their scents intermingle throughout the home, facilitating peaceful coexistence.
Startle Reflex and Stimulus Overflow
Cats startle easily, instantly leaping into an explosive fight-or-flight response. Their sharp hearing detects subtle noises unnoticed by human ears. Meanwhile, dogs bound excitedly upon your arrival, barking boisterously with vigorous tail wags. This stimuli overload often overwhelms cats, explains Jackson Galaxy, host of Animal Planet’s My Cat from Hell. He suggests establishing a relaxing cat den in a spare room or closet — their private oasis when madness erupts — to acclimate cats gradually to dogs and bustling household activities.
Independent and Observant Nature
Unlike affection-craving canines, cats treasure self-sufficiency. They perch serenely, gazing out windows for hours, mesmerized equally by birds…or dust particles. Their patience and stillness contrast sharply with a dog’s restless energy. Prominent veterinarian Dr. Justine Lee confirms that this causes interspecies miscommunications. She reminds owners that cats speak a subtler language – slight ear flicks, whisker movements, shifting pupil sizes. Learning these nuances prevents misunderstandings, leading to swipes and nips during rare interactions.
Prey Drive and the Chase Reflex
Despite domestication, cats retain their predatory origins, instinctively stalking and pouncing on prey. When your energetic retriever bounds towards them, cats instantly flee, triggering their chase reflex. They aren’t playing – they feel pursued by danger. Keep initial meetings extremely calm. Secure excitable dogs with leashes during early encounters and provide cats an escape route onto high perches. This precaution converts predatory arousal into harmonious habits.
Understanding Dog Behavior
To promote household harmony between dogs and cats, we must first comprehend the key components of canine psychology. As certified dog trainers and veterinary behaviorists emphasize, observing the nuances of your dog’s conduct reveals invaluable insights for facilitating peaceful coexistence. For example, you can learn different behaviors, including why your dog might stare at you.
The effervescent energy intrinsic to dogs often bewilders their feline housemates. Canine experts confirm that most breeds retain high activity levels from hunting and working origins. When your Labrador retriever ecstatically zooms after a ball or Frisbee, cats perceive this as predatory behavior directed towards them.
Provide dogs with sufficient outdoor exercise and interactive toys to channel their enthusiasm. Also, incorporate training to hone impulse control. For example, reward your puppy with treats for remaining calmly seated during your arrival home or when cats saunter by. This curbs obtrusive chasing or barking, which stresses reticent kitties.
Pack Mentality and Social Structure
Dogs are instinctually pack animals, hardwired to adhere to hierarchical social order. Certified dog trainer Zak George explains that your dog views family members as their pack and you as the benevolent leader. This contrasts significantly with cats’ solitary dispositions. Proper socialization prevents dogs from harassing cats or perceiving them as threats to the pack’s cohesion.
Additionally, the innate compulsion to sniff unfamiliar creatures compels countless dogs to eagerly investigate newcomer cats. Instead of allowing free access, keep early encounters structured and optimistic. With patience, your dog will eventually consider kitty companions part of their extended clan.
Bounds of Loyalty
Man’s best friend earned their moniker through unwavering devotion to owners. Yet this loyalty breeds an intense impulse to protect their loved ones from perceived danger – including unfamiliar cats suddenly introduced into their domains. To avoid adversarial showdowns, certified dog trainer Victoria Stillwell advises owners to slowly acclimate both pets in neutral territory, providing favorite treats as favorable reinforcement. Loyalty is one of the things dogs are showing when they lay on their owners.
Gradually increase exposure time while preventing negative interactions that would cement animosity. As trust in their owner’s judgment builds, most dogs will accept feline houseguests.
Preparing Your Home
Crafting a harmonious habitat for cats and dogs necessitates thoughtful preparation tailored to their needs. A shared living space should balance safety, comfort, and minimal stress for all inhabitants. By catering to essential creature comforts for each species, your pet-friendly sanctuary will soon resound with merry barks and contented purrs.
Designating Separate Retreats
Allocating personal quarters for solitary relaxation proves vital, especially during introductory phases when newcomers acclimate. Build or purchase enclosed litter box furniture with entry holes sized exclusively for cats. Affix clawed scratching posts vertically and horizontally, suitable for stretching and scratching urges. Position these cat-only zones in quiet areas.
For dogs, define an exclusive domain for naps and refuge when craving peace. Ideal havens include roomy crates padded with plush beds, preferably with privacy flaps. Place these shelters out of high-traffic pathways in calmer environments. If possible, establish a specific room to serve as a dog retreat. Stock it amply with safe chew toys.
By honoring an innate survival impulse for private dens, both species relish personal pampering, napping undisturbed for hours. When they later emerge seeking socialization, peaceful mingling unfolds more naturally.
Implementing Vertical Dimensions
Since cats feel more secure when perched high observing their surroundings, incorporate vertical elements throughout shared territories. Install shelving, cat trees, and wall ledges offering birds-eye vistas. Ensure ample leaping space between platforms, enabling exercise through daring aerial feats. Obstacle course additions like tunnels and hidey-holes maintain mental stimulation.
Position food bowls and litter boxes on raised surfaces as well. This prevents dogs from gulping kitty cuisine or leaving smelly surprises. Consider mounting window sill perches for homes without space for towering cat jungle gyms. These mini-sanctuaries allow safe monitoring of bustling household activities.
Preparing for Playtime
While independent kitties entertain themselves for hours, dogs thrive when interacting with human companions. Make playtime engaging by investing in food puzzle toys and challenging chews. Schedule regular vigorous romps fetching tennis balls or flying discs in securely fenced yards. Just 15 minutes daily drastically reduces nuisance barking or hyperactivity annoying cats.
Construct two separate play zones – one for boisterous dogs and another for climbing and pouncing cats. Install modular wall panels, allowing customization when territories merge. With ample outlets for play, pesky puppies refrain from tailing restless cats seeking solitude. As both pets age, early investments in designated recreation areas satisfy their distinctive needs.
The initial introduction between cats and dogs marks a pivotal moment, setting the tone for peaceful cohabitation or endless chaos. As certified animal behavior experts emphasize, a structured acclimation process allows both species to familiarize themselves slowly, alleviating fears that kindle aggression. You foster tolerance, curiosity, and lasting companionship by patiently orchestrating controlled interactions.
Designating a Neutral Zone
When bringing home a new cat or dog, immediately confine them to a neutral room, advises Jackson Galaxy. Outfit this transitional space with bare essentials – food, water, litter box, plush bed – minimizing external stimuli. Over several days, let current residents approach the closed door, sniffing and detecting the newcomer. Swap blankets between rooms so scents intermingle. This crucial step previews impending change, explains Galaxy, making introductions less alarming.
Calm First Impressions
After several days, allow brief supervised meetings on neutral turf like the backyard, keeping both pets leashed initially. “Prevent chasing or roughhousing, which would trigger fearful reactions,” cautions Dr. Justine Lee, DVM and author of It’s a Dog’s Life. Treat new friends to tasty morsels when remaining calm, reinforcing polite behavior. If showing signs of distress, promptly guide animals back to their sanctuaries.
Following peaceful encounters, let feline and canine investigators explore each other’s quarters, cementing constructive associations through scent exposure. “Rub a towel on one animal, then place it in the other’s domain so they grow accustomed to the smell,” advises veterinary behaviorist Dr. Sophia Yin. This builds anticipation for amicable interactions versus perceiving intruders.
While monitoring early interactions, offer encouraging praise and treats for positive behavior, ensuring first impressions remain heartening. Certified dog trainer Victoria Stillwell suggests briefly leashing over-eager pups if chasing commences. Provide cats an escape route onto high shelves when feeling overwhelmed. “Set the path for friendship through compassion,” urges Stillwell. “Admonishing aggression or forcing proximity creates adversity.”
Training for Cohabitation
Establishing harmonious multi-pet households requires dedication and patience. Professional trainers emphasize that proper training curbs undesirable behavior while catalyzing friendships between historic adversaries. You unlock the secrets of peaceful coexistence by compassionately coaching cats and dogs.
To reduce territorial tussles, establish clear boundaries separating dog and cat zones. Certified pet trainer Zak George suggests designating feeding, napping, and play areas. As kittens need to be fed more frequently, attention is needed. Initially monitor all interactions, praising and rewarding positive behavior with treats. If aggression surfaces, promptly guide pets back to their respective quarters.
Gradually permit mingling during structured play sessions. Let curiosity bloom by allowing gentle sniffing and tentative greetings. With ample praise and patience, pets soon learn to respect each other’s personal space.
From exuberant zooming to obsessive barking, dogs often perplex their feline roommates. Consult accredited trainers to instill obedience basics like ‘sit,’ ‘stay,’ and ‘quiet.’ “This establishes you as the calm leader of the pack,” explains Stillwell. Set clear expectations for manners around cats, rewarding compliance, and redirecting over-eagerness.
Additionally, condition dogs to remain composed when you return home or greet new guests. Calm entrances prevent the stimuli overload that triggers a cat’s instinct to flee. With diligence, rambunctious pups morph into courteous companions.
Through incremental exposure therapy, you can recondition instinctual fear responses between species. “Let animals spend brief supervised time together, then reward any progress with praise or treats,” advises Jackson Galaxy. For example, when a timid kitty emerges from hiding, applaud their bravery and offer a tasty morsel.
Galaxy also suggests that rubbing scents between animals can help recondition reactions. Place cat toys briefly with calm dogs to intermingle smells. Repeat exposure diminishes knee-jerk apprehension, allowing curiosity to bloom.
Introducing a new furry friend into your home can lead to some predictable challenges as existing pets adjust. Pet psychologists and veterinarians provide insights on navigating typical issues to help cats and dogs live harmoniously.
Rivalry Over Resources
As cats and dogs stake claims over newly shared territory, competition may arise over resources like food, beds, and human attention. Canine behaviorist Victoria Stillwell explains that establishing clear boundaries and schedules helps diffuse tension.
“Feed pets in separate areas and remove the food bowls when they finish meals,” she advises. Stillwell also warns against playing favorites. “Divide equal cuddling time to prevent jealousy. And provide plentiful beds, window perches, and scratch posts so everyone enjoys prime real estate.”
Stress-Induced House Soiling
The stress of a new animal’s presence may cause lapses in housetraining or litter box errors. “Marking territory with urine or stools communicates insecurity,” notes Jackson Galaxy. “This usually resolves as confidence builds.”
Veterinarian Sophia Yin suggests confining newcomers to a single room initially with food, water, toys, and litter. “Once they acclimate fully, allow short supervised encounters. If accidents occur, interrupt promptly and return pets to their enclaves.” Increased exercise and play alleviate underlying stress as well over time.
Kittens, seniors, and unsocialized pets pose higher aggression risks. Warning signs involve tense body language – ears back, growling. “If intimidation continues, separate immediately,” says Dr. Yin. “Then reintroduce very slowly, keeping pets leashed and rewarding friendly behavior with treats.”
As a last resort for serious discord, consult an animal behavior specialist. Special pheromone diffusers and flower essences may curb hostility chemically. In rare cases of potential danger, permanent separation proves essential. With patience and care, however, most furry housemates eventually bond.
In our journey through the intricacies of cats and dogs living together, we’ve uncovered a wealth of information illuminating the path to harmonious coexistence. The potential for peace and friendship between these historically misjudged rivals is not only possible but profoundly enriching for them and their owners.
With patience, knowledge, and the right approach, cats and dogs can share a home in harmony. From creating a pet-friendly environment to understanding their communication cues, we’ve explored practical strategies that help bridge the gap between feline and canine worlds.
In fostering this unity, we not only enhance the lives of our pets but also enrich our own. Let this guide be your starting point to a home where cats and dogs live together, not as rivals, but as companions in a shared, loving space.

Robbery is the crime of taking or attempting to take anything of value by force, threat of force, or by putting the victim in fear. According to common law, robbery is defined as taking the property of another, with the intent to permanently deprive the person of that property, by means of force or fear; that is, it is a larceny or theft accomplished by an assault. Precise definitions of the offence may vary between jurisdictions. Robbery is differentiated from other forms of theft (such as burglary, shoplifting, or car theft) by its inherently violent nature (a violent crime); whereas many lesser forms of theft are punished as misdemeanors, robbery is always a felony in jurisdictions that distinguish between the two. Under English law, most forms of theft are friable either way, whereas robbery is friable only on indictment. The word “rob” came via French from Late Latin words (e.g., deraubare) of Germanic origin, from Common Germanic rub — “theft”.
Armed robbery, in criminal law, aggravated form of theft that involves the use of a lethal weapon to perpetrate violence or the threat of violence (intimidation) against a victim.
Armed robbery is a serious crime and can permanently traumatize its victims, both physically and psychologically. It tends to receive considerable media attention when it occurs, and it carries longer prison terms than other forms of robbery such as simple robbery (i.e., theft without a dangerous weapon). Armed robbery is typically motivated by the desire to obtain money, which is then often used to purchase drugs; however, some armed robbers engage in the crime with the intention of boosting their status within their peer group. Whatever the motivation, the act is classified as a violent crime, because armed robberies can result in injury and sometimes death to victims.
Armed robbers are disproportionately young males who are clearly opportunistic in their selection of easy targets. Armed robbery may occur on the street—where unsuspecting individuals are held up at gunpoint—or in a commercial establishment such as a convenience store or a bank. Several studies have determined that armed robbers prefer isolated locations with lone victims and reliable escape routes. As a result, increasing public awareness of the crime and providing businesses with enhanced security and surveillance are thought to reduce the incidence of armed robbery. Law-enforcement authorities can further reduce the chances of armed robberies occurring by monitoring places known for high incidences of the crime and engaging in aggressive patrols and intervention to deter potential offenders
Armed Robbery, according to the laws of the state of Arizona, occurs whenever a weapon is used in the commission of a robbery theft. The weapon can be a gun, knife or any other deadly weapon. You can be charged with robbery even if the weapon is not pointed at the victim. It’s also an armed robbery charge without a weapon if you give the impression of having a weapon and the victim has a reasonable cause to believe you. An example might be using your finger inside a jacket pocket to give the impression you have a gun. That’s enough to satisfy the requirement for an armed robbery charge.
The Charge of Robbery
Taking property from another person – Robbery begins when someone takes personal property (not real property, such as land or buildings) that someone else possesses, without the person’s consent. The victim need not actually own the item taken; it’s enough that he has mere possession. For example, forcefully taking a library book from someone would qualify, even though the victim doesn’t own the book.
Taking property from another’s person or presence – Unlike simple theft (like taking an item from a store), robbery involves taking something from a person. This includes not only taking something from one’s grasp, such as hitting someone in order to cause him to lose his grasp of his briefcase, but taking something from someone’s presence.
Items that are within a person’s presence are close to the victim and within his control. For instance, locking a clerk in a storeroom after forcing the clerk to open the safe would constitute robbery, because the safe was under the control of the clerk. Another way of understanding this is to say that the money in the safe was within the clerk’s control in that he could have prevented the taking but for the robber’s threats or violence.
Some states, however, don’t require that the item be taken from the person or his presence. In these states, the use of violence or threats in conjunction with the theft will suffice.
The property must have been carried away – The law requires that the defendant actually carry the property away, even slightly. Sometimes, merely exercising control over the item taken will suffice. For instance, intending to take a camera, a thief places his hands on the case that hangs from the victim’s shoulder. Although he is stopped before he could move it, in most states, this act would suffice for “control.”
Intending to permanently deprive the possessor – The person who has taken another’s property must have intended at the time to permanently deprive the victim of that property. Taking something with the intent of using it in a way that creates a high likelihood that it will be permanently lost is sufficient. For example, taking a cell phone with the intent of using it and abandoning it creates a substantial risk that it will never be returned.
Taking by violence or intimidation – Taking someone’s property is robbery if any force is used to obtain it. Pushing someone down, hitting someone, wresting something from the victim’s grasp are all examples of violence. There need not be a lot of force—a light shove or the snapping of a purse strap will do.
Robbery can also be accomplished by intimidating someone—placing someone in fear. But in some states, that fear must be reasonable—the response of any ordinary person in the position of the victim. Other states will count a victim’s unreasonable response (the response of someone unusually susceptible to threats), as long as it was triggered by the defendant’s actions.
Traditionally, the threat needed to be one of serious injury or death, or the destruction of the victim’s home; and the threat needed to be of imminent harm. For example, threatening to do harm to the victim’s family member many months hence is not imminent enough to qualify as a threat.
Using a dangerous weapon – As explained above, “armed robbery” is usually charged as an aggravated robbery, which requires the use of a deadly or dangerous weapon. There’s little debate whether a functioning firearm qualifies as a deadly or dangerous weapon. But other objects can qualify, as long as they are inherently deadly, or if not, used in a manner that causes or is likely to cause serious physical injury or death. Many debates surround items like stationary objects, canes, animals, parts of the human body, and vehicles.
Robbery Crimes Defined
Attempt to commit – Aggravated robbery charges are often brought based on the actions taken immediately before and after the incident. For example, fleeing the scene of the attempted crime can constitute these charges.
Although in Salt Lake City armed robbery and aggravated robbery are often used interchangeably, the statute only refers to aggravated robbery because it is more comprehensive, it includes the following:
• the use or threat of use of a dangerous weapon
• causing serious bodily injury
• taking or attempting to take an operable motor vehicle in the course of committing robbery
Aggravated robbery is a First-degree felony crime. This is considered one of the most serious crimes a person may be charged with. It is indispensable to engage the services of an experienced Salt Lake City lawyer who can vigorously defend and advocate for your rights.
Helping people charged with robbery minimize the serious consequences
The consequences of a robbery conviction can be severe, both immediately and in the long term. If you have been charged with robbery, your best course of action is to talk with a criminal defense attorney at Ascent Law in Utah, who has extensive experience and knowledge of Utah robbery laws. It is crucial that you speak with an attorney about your robbery charge before you talk with the police or answer any questions. Lawyers can advise you of your options and help ensure your rights are not violated. Robbery defendants who have a knowledgeable lawyer working on their behalf usually get a better outcome with lesser consequences than those who do not.
Penalties for robbery convictions
Under Utah robbery laws, robbery is a second-degree felony with penalties that can include one to fifteen years in prison and a fine of up to $10,000. Aggravated robbery is a first-degree felony, for which penalties can include five years to life in prison and a fine of up to $10,000. In addition, in most robbery and aggravated robbery cases, the Utah court orders the defendant to pay restitution to the victim, whom means that you must repay the victim for the property that, was taken if you are convicted. Finally, a felony conviction remains on a person’s criminal record and is accessible to anyone who looks it up.
Utah Felony Criminal Penalties
Sentencing and Aggravating Factors – Minor criminal offenses are called misdemeanors, while more serious offenses are categorized as felonies. Robbery is always a second degree felony, which in Utah can result in a maximum fine of $10,000 and a prison sentence ranging from one to 15 years in prison.
Judges have discretion over the duration of a convicted defendant’s prison sentence. A sentence may be longer if the court finds any aggravating factors, or aspects of the crime that enhance penalties. Examples of aggravating factors include:
Committing a crime on school property.
Endangering a child while committing the crime.
Committing a hate crime.
Robbery becomes aggravated robbery, a first degree felony, if the defendant caused serious injury or used a dangerous weapon while committing, attempting to commit, or fleeing from the crime. Actual or attempted robbery of a working, usable car or other motor vehicle is also aggravated robbery. Utah penalties for a first degree felony can include a fine up to $10,000 and a sentence ranging from five years to life in prison.
Reasons You Can Be Charged With Robbery
Being charged with robbery is not the same as being charged with theft or burglary, which are separate crimes. Robbery has a distinct definition which sets it apart from these and other related offenses. Defined under Utah Code §76-6-301, robbery is charged when a suspect allegedly:
Steals or tries to steal another person’s property, against the victim’s will, by using force or putting the victim in fear for their personal safety. It does not matter whether the defendant meant to take the property permanently or temporarily.
Deliberately using force, or deliberately putting the victim in fear for their personal safety, while committing theft or taking property that isn’t lawfully yours. That includes attempted theft, actual theft, and/or fleeing from the scene of a theft.
If the suspect did not use force or put the victim in a state of fear, the elements of the charge are not met. Stealing without using force or fear is theft or wrongful appropriation — which are also serious allegations. If you or one of your loved ones has been accused of any form of theft, burglary, or robbery in Utah, you should contact a criminal defense attorney for help right away
Get Legal Help for Armed Robbery
As with any felony charge, it is essential to consult with a criminal defense attorney as early as possible in the case. An experienced defense attorney will be able to help you understand the charges against you and the weight of the evidence the prosecution intends to produce. A good attorney will be able to realistically assess your chances at dismissed or reduced charges, a plea bargain, or the likely consequences should you go to trial as charged. Only someone who is familiar with how the prosecutors and judges in your courthouse approach cases like yours will be able to give you this essential information.
A robbery conviction has both immediate and long-term consequences. First, you can receive a lengthy prison sentence. Then, once you have served your time and been released, you will have a permanent criminal record which can prevent you from getting hired for jobs, or approved for professional licenses. You can also lose your gun privileges. It is critical that you have a skilled and tenacious criminal lawyer on your side.

Advantages and Disadvantages of Paraprofessional and Professional Careers
Choosing a career path is one of the most important decisions that you will make in your life. It can determine your future success, your financial stability, and your overall happiness. When it comes to selecting a career, there are two main options: paraprofessional and professional careers. In this article, we will discuss the advantages and disadvantages of paraprofessional and professional careers.
Paraprofessional careers are those that require less education and training than professional careers. These careers typically require a high school diploma or a two-year associate degree. Some examples of paraprofessional careers include teacher assistants, dental assistants, medical assistants, and veterinary technicians.
Advantages of Paraprofessional Careers
One of the main advantages of paraprofessional careers is that they require less education and training than professional careers. This means that you can enter the workforce sooner and start earning money. In addition, paraprofessional careers typically have lower student loan debt compared to professional careers.
Another advantage of paraprofessional careers is that they offer a quicker path to career advancement. While professional careers may require years of additional education and experience, paraprofessional careers often have opportunities for on-the-job training and promotions. This can allow you to quickly move up the career ladder and increase your earning potential.
Disadvantages of Paraprofessional Careers
One of the main disadvantages of paraprofessional careers is that they typically have lower salaries compared to professional careers. Additionally, there may be limited opportunities for career growth and advancement beyond a certain point. This can lead to job dissatisfaction and a lack of motivation to continue in your career.
Another disadvantage of paraprofessional careers is that they may be physically demanding and require long hours on your feet. This can be exhausting and lead to burnout over time.
Professional careers are those that require a higher level of education and training. These careers typically require a bachelor’s degree or higher, and examples include doctors, lawyers, engineers, and accountants.
Advantages of Professional Careers
One of the main advantages of professional careers is that they offer higher salaries and greater earning potential compared to paraprofessional careers. This is due to the higher level of education and expertise required for these careers.
Additionally, professional careers often offer more job security and benefits, such as health insurance and retirement plans. Another advantage of professional careers is that they often provide greater opportunities for career growth and advancement. This can include promotions, salary increases, and the ability to specialize in a specific area of the field.
Disadvantages of Professional Careers
One of the main disadvantages of professional careers is the amount of time and money required to obtain the necessary education and training. This can result in significant student loan debt and a delay in entering the workforce.
Additionally, professional careers may require long working hours and high levels of stress, which can lead to burnout and job dissatisfaction.

Paraprofessionals vs Professionals: Which Offers Better Job Security?
When it comes to job security, both paraprofessionals and professionals can have stable careers. However, there are a few key differences to consider.
Paraprofessional jobs, such as teacher aides, healthcare assistants, or administrative assistants, may be more susceptible to budget cuts or changes in demand. These positions may be viewed as more expendable compared to professional jobs, which require specialized knowledge and skills.
On the other hand, professional jobs often require advanced degrees or extensive training, which can make them more competitive and in demand. Professionals may also have more job security due to their ability to take on leadership roles or specialized positions within their field.
Another factor to consider is the industry or sector in which the job is located. Some industries, such as healthcare or education, may have more stable job markets and higher demand for both paraprofessionals and professionals.
Ultimately, job security is dependent on a variety of factors, including industry trends, the economy, and individual job performance. It’s important to research the specific job and industry you’re interested in and consider the potential for that.
Advantages and disadvantages of paraprofessional and professional careers: Salary Comparison
When it comes to salary, professional careers tend to pay more than paraprofessional careers. Professionals often have higher levels of education and experience, which translates to higher salaries. However, it’s important to note that paraprofessionals can still earn a decent living, especially if they have specialized skills or work in high-demand fields.
Advantages and Disadvantages of Paraprofessional and Professional Careers: Education Requirements
Professional careers usually require a higher level of education than paraprofessional careers. For example, a doctor or lawyer requires years of education and training, while a paraprofessional may only need a high school diploma or some college education. However, this also means that paraprofessional careers may have fewer barriers to entry, making them more accessible to a wider range of people.
Advantages and Disadvantages of Paraprofessional and Professional Careers: Day in Life
The day-to-day tasks of paraprofessionals and professionals can vary widely. Paraprofessionals may work in fields such as education, healthcare, or social work, and their duties may include assisting with patient care, providing classroom support, or helping clients access resources. Professionals, on the other hand, may work in fields such as law, medicine, or engineering, and their tasks may include conducting research, managing teams, or providing expert advice.
Job Satisfaction: Paraprofessional vs Professional Career Comparison
Job satisfaction can be subjective and varies from person to person. However, research suggests that professionals tend to report higher levels of job satisfaction than paraprofessionals. This may be due to factors such as higher salaries, more autonomy, and greater job security.
Skills Needed for Success: Paraprofessional and Professional Career Comparison
Both paraprofessional and professional careers require specific skills for success. Paraprofessionals may need skills such as communication, organization, and empathy, while professionals may need skills such as critical thinking, leadership, and problem-solving. It’s important to note that many of these skills can be developed over time with education and experience.

Role of Family Nurse Practitioner
Nurse Practitioners (NP) play a vital role in the delivery of primary care in the United States. This is especially considering the fact that 89% of the population of NPs are actively involved in primary care provision. There is a lot of evidence to demonstrate that the primary care’s cost effectiveness and high quality are attributed to the NPs (Buppert, 2012). Therefore, there has been a growing interest in the field by students of various nursing disciplines to take part in primary care dilemma solution.
The scope of practice for NP includes blending medical and nursing services to groups, families and individuals. NPs are involved in the diagnoses and management of chronic and acute conditions as well as emphasizing disease prevention and health promotion initiatives. Some of the services include conducting, interpreting and ordering laboratory and diagnostic tests, non-pharmacologic therapies and pharmacologic agents’ prescription as well as provision of guidance and services. They practice both independently and in collaboration with the rest of the professionals involved in health care provision.
As a process of preparation, the NPs undergo through a rigorous academic training journey in different academic levels like graduate, master’s or doctoral. Some of these academic programs include clinical and didactic courses that are designed to offer graduates with clinical care and specialized knowledge competencies. As professional members, the NPs are responsible for the advancement of the NP roles, specification of professional competencies and standards and making sure that all these are accomplished.
Almost the entire population of the NPs is prepared in the focus of primary care such as family, pediatric, adult, women’s health and gerontological health.
However, the family nurse practitioner (FNP) focus is the most predominant category. However, irrespective of their population focus the primary care NPs are trained and ready to accomplish the primary care objectives across different settings such ongoing chronic and acute conditions management, care coordination and health promotion as well as first contact care provision for conditions that are undifferentiated. The last few years witnessed the rapid growth in the number of students who are enrolling and graduating in NPs programs (Grossman & O’Brien, 2010). This points to a greater future ahead where many NPs will be prepared to handle family health.
Practice Focus Justification
Family nurse practitioners forms the largest NPs proportion in the United States. By 2016, more than 55% of the 220,000 licensed nurse practitioners worked under the family health field. There is a lot of evidence that the NPs provide quality and cost-effective health services and thrive in those states that assure them of full practice. However, the NPs are still fighting for their professional autonomy, which they argue, do not correspond to their level of preparation and training. In some states, the diagnosis and treatment for patients are entirely performed by the physicians while the NPs are only allowed to do the periphery cares that limits their engagements professionally. Few states however have collaborative professional practices between physicians and family nurse practitioners. Best services are achieved if there are collaborative services among all health care professionals.
By definition, scope of practice implies a set of actions, processes, and procedures that a nurse practitioner is lawfully permitted to undertake. Apparently, scope of practice changes from one state to the other but is always governed by the relevant laws in those states. Nurse practitioners are independent and licensed practitioners who are mandated to practice in long term, ambulatory and acute care units as providers of specialty and primary care. They diagnose, manage, assess, and treat chronic and episodic illnesses. Besides, they are also specialists in disease prevention and health promotion (Zaumeyer, 2003). Moreover, the nurse practitioners also conduct, interpret, order, and supervise laboratory and diagnostic tests, prescribe both nonpharmacologic agents and pharmacologic agents in addition to counselling and teaching patients and their families on various care initiatives.
A NP and a physician have similar scopes of practices. However, they are quite different when it comes to registered nurse (RN) who is registered to carry out nursing diagnostic and implement treatment like in health education. On the other hand, NP implements such treatments as diagnostic imaging, invasive procedures, and prescription medication. Nonetheless, both the RNs and NPs are allowed and trained to carry out independent practices despite the differences in their scope of practice.
Independent practice is one of the core mandates of NPs. It refers to an ability of the NP to offer care and treatment without direct supervision from a doctor. Therefore, an NP from independent practice granted states can diagnose, treat, and assess a patient just as a physician could have done it. It is important to note that all NPs are trained to offer care to patients without being supervised by physicians. Nonetheless, in some states, the NPs are required to pay physicians if they supervise their works. This implies that different states have different degrees of independence. Consequently, it has a remained a contentious topic among national organizations that represent both the physicians and the NPs.
Various degrees of independence among different states can be categorized under full practice, reduced practice, and restricted practice. The full practice is entirely independent while the reduced practice is partially independent. On its part, the restricted practice is not independent at all. The NPs in full practice can provide full care to patients without the involvement of physicians. Meanwhile, those in the states of reduced practice can provide care to patients but would require the involvement of physicians to some level. These levels of involvement include meeting some patients as well as discussing patient cases with the nurses (Cash & Glass, 2011). Conversely, states with restricted practice laws prevent NPs from offering care to patients despite being educated to do so. Instead, there must be a supervisory agreement between the doctors in charge and the NPs. Incidentally, this is a very costly exercise.
Evaluation of the Professional Image of NPs
Since the year 1999, the nurses in the United States have often topped the list of eleven professions with the highest ethical standards and honesty, according to the Gallop poll. They have always been ranked higher than the clergy, the medical doctors and law enforcement officers. One of the most outstanding features of the NPs profession is their uniforms, which some pundits have argued that do not evoke immediate respects and recognition as does the white coat worn by the physicians. Today, it is becoming difficult to tell who a NPs is from a group of health care professionals.
Nurse practitioners have long been identified by their standardized uniforms since the year 1836. Although the stark white outfits professionally worn by the NPs did not have any direct impact on how they provided primary care to their patients, they made them stand out and completely communicated an unambiguous role about the wearer. The outfits were impressive and demonstrated their professionalism. However, this situation would later change in the 1970s when major changes were introduced to the nursing professional outlook, which affected their uniforms (Way, Jones, Baskerville, & Busing, 2001). Some of the cultural changes responsible for this change of events included the liberation of women and sexual orientation. From there things started getting more colorful and casual.
The white attire that was worn from head to toe and the starched caps were abandoned from scrubs of different patterns and colors that depicts different characters including those in cartoons. The scrubs were deemed to revolutionize the professional image of the NPs. It was argued that they were practical and evolutionary advancements to their professional image. However, the same could not be said of the wide variations of NPs uniforms that characterized their workplaces. Ultimately, they confused the patients even more. It subsequently gave rise to a debate of whether the NPs’ professional image genuinely portrayed the knowledge, compassion and level of expertise that nurses ought to possess (Cash & Glass, 2011). Indeed, the image portrayed by the nurses should elevate their professionalism sense and emphasize their sense of commitment and care for their patients.
Some scholars have argued that a standardized uniform color and style among the NPs is a clear demonstration of the increased perception of recognition and professionalism of the NPs among their patients and their families. However, this can be misleading as it proves that the NPs uniforms is an issue of patient safety, which apparently is not the case since a patient can as well receive a false information from assistive personnel who is not licensed to deliver the same. While it is true that patients need to know who their NPs are, and they can easily do that if they wear the right uniform, it is also true that assistance can come from other health care professionals like a care technician for instance. This means that the idea of a uniform as a professional image depiction is defeated in this case.
Proper distinction of health care staff duties in patient care is captured under the Nurse Title Protection legislation, which was enacted in March 2015 across 38 states to among other things avoid misrepresentation of persons unlicensed and uneducated to practice nursing as well as ensure the provision of quality and safety of patient care. This legislation helps to restore the NPs’ professional image as it prohibits persons who are not licensed as nurse from using the title. By reserving the NPs title for only those persons who have genuinely met the licensing and educational standards of a nurse, the public can adequately distinguish a nurse practitioner who is licensed from other providers of health care. This is appositive trend that also boosts the NPs’ professional image and can be better achieved if the uniform style of the NPs is standardized.
Research by different professional organizations such as the PAH Professional Image Council (PIC) have established that the identity and awareness of the hospital staff by patients and their interdisciplinary collaboration are at the cornerstone of achieving effective, quality and safe health care as well as patient outcomes that are positive. Nonetheless, a substantial number of patients have also confessed that patterned and brightly colored scrubs confuse them in their attempts to distinguish the NPs from other health care staff (Zaumeyer, 2003). Indeed, some are not even aware if the health care professional caring for them is a NP or not.
The attire and color worn by a NPs sends vital messages to a patient about the quality and skills that the nurse would dispense to the given patient. In fact, it is more effective than the identification badge worn by nurses in identifying the NP. On the contrary, the badge is mostly difficult to read by patients, some of which must be very close to it. This is a further indication that the professional image of a NPs goes beyond a neck tag. While many nurses prefer a certain kind of bright colored attire for their professional image, patients do not have any preference as long as the NPs’ nurses do not affect their care delivery. All that the patients need are attires that make the NPs comfortable and flexible in executing their duties as care givers.
Standardizing the professional image on the NPs is however a contentious issue as some nurses feel that somebody is dictating their individualities. This is a very big challenge since most nurses feel that their profession is isolated for discrimination. But it is vital that the NPs understand that nursing is more than a profession, it is a calling (Buppert, 2012). Hence, one should elevate his or her thinking beyond the profession tag and desist from the mentality of ‘being victimized’ and in its place embrace a model of patient centeredness.
Nurse Practitioners (NP) play a vital role in the delivery of primary care in the United States. The scope of practice for NP includes blending medical and nursing services to groups, families and individuals. They are involved in the diagnoses and management of chronic and acute conditions as well as emphasizing disease prevention and health promotion initiatives. However, the professional images depicted by the NPs matters a lot when it comes to primary care deliver. When the NPs professional image is standardized, a nurse gets a sense of pride in his or her profession. This makes them feel acknowledged and appreciated for their education and knowledge. Additionally, patients also get it easy to identify their nurses while in the hospital. This initiative can inspire other hospital departments such as radiology, respiratory, escort and laboratory services especially if successful to understand that standard color uniform boosts professional image.

Understand the causes and treatment options for Klumpke’s paralysis and when your child might be entitled to compensation
Klumpke’s palsy, also known as Klumpke’s paralysis, is a rare but significant birth injury that affects the brachial plexus, a network of nerves near the neck that are responsible for controlling the muscles in the shoulder, arm, and hand.
Characterized by weakness or paralysis in the forearm and hand, Klumpke’s palsy can result in a range of motion difficulties and, in some cases, a permanent disability if not treated promptly and appropriately.
This article aims to shed light on Klumpke’s palsy, exploring its causes, symptoms, treatment options, and the long-term outlook for affected infants, providing essential information for parents and caregivers navigating the challenges of this birth injury.
What are birth injuries of the brachial plexus?
Brachial plexus birth injuries occur when the network of nerves responsible for sending signals from the spine to the shoulder, arm, and hand, known as the brachial plexus, is damaged during childbirth.
This damage can lead to varying degrees of arm weakness, loss of muscle control, or paralysis in the affected newborn. These injuries often result from excessive stretching of the baby’s neck to one side during a difficult delivery.
Two of the most common types of brachial plexus injuries are Erb’s palsy and Klumpke’s palsy.
What is the difference between Erb’s palsy and Klumpke’s palsy?
Erb’s palsy and Klumpke’s palsy are both types of brachial plexus injuries but affect different areas of the brachial plexus network, leading to distinct symptoms and areas of paralysis or weakness in the affected arm.
Erb’s palsy typically results from damage to the upper brachial plexus. This injury most commonly occurs during childbirth when there is excessive pulling on the baby’s head and neck to one side as the shoulders pass through the birth canal.
The primary manifestation of Erb’s palsy is weakness or paralysis in the shoulder and bicep muscles, leading to a limited ability to move the affected arm, although there may still be movement in the fingers.
A classic sign of Erb’s palsy is the “waiter’s tip” position, where the arm is held at the side with the forearm turned inward and the wrist flexed.
Klumpke’s palsy, on the other hand, affects the lower brachial plexus. It is less common and often results from an upward pull on the arm during delivery.
Klumpke’s palsy is characterized by paralysis or weakness in the muscles of the forearm and hand, leading to a claw-like deformity of the hand and fingers. In severe cases, it can also affect the muscles of the wrist and fingers, severely limiting hand movement.
What nerves are damaged in Klumpke’s palsy?
In Klumpke’s palsy, the injury involves the lower brachial plexus, particularly damaging the C8 and T1 nerve roots. These nerves are crucial for the movement and sensation in the forearm and hand, leading to characteristic symptoms such as weakness, paralysis, and a “claw-like” deformity of the hand and fingers when these specific nerve roots are affected.
Why does Klumpke palsy result in claw hands?
As previously discussed, Klumpke’s palsy occurs when specific nerves in the baby’s lower neck, which are part of what’s called the brachial plexus, get injured. These nerves are like the body’s electrical wires that control the muscles in the forearm and hand. When these nerves get damaged, they can’t send the right signals to the muscles in the hand and forearm.
Because of this, the hand forms a claw-like shape where the fingers are bent at the joints, creating the “claw hand” appearance. This happens because the muscles aren’t working together as they should, leading to an imbalance and the characteristic hand posture seen in Klumpke’s palsy.
What is the prognosis for Klumpke’s palsy?
The prognosis for Klumpke’s palsy can vary significantly depending on the severity of the nerve damage.
This suggests that many individuals with Klumpke’s palsy may experience significant improvement or even full recovery of function without the need for surgical intervention, especially if the nerve damage involves neurapraxia, which is the mildest form of nerve injury characterized by a temporary loss of nerve function.
However, it’s important to note that some cases of Klumpke’s palsy can result in permanent disabilities, ranging from mild to severe. The extent of recovery often depends on the type of nerve damage and the timely initiation of treatment, including physical and occupational therapy.
Early and consistent rehabilitation efforts can optimize the chances of recovery by preventing joint stiffness and improving muscle strength and function. In instances where nerve damage is more severe and spontaneous recovery is not achieved, surgical options may be considered to repair or graft nerves to restore function, although outcomes can vary.
Is Klumpke’s palsy always the result of a preventable birth injury?
Klumpke’s palsy is not always the result of a preventable birth injury. However, certain medical mistakes, can lead to this type of brachial plexus injury, including:
- Mismanaging fetal malposition (breech birth) or fetal macrosomia (large baby)
- Mishandling the baby during delivery or improperly using forceps or a vacuum extractor
- Failing to address delivery complications promptly (e.g., failing to perform a necessary cesarean section (C-section) when medically indicated)
Since it’s challenging to discern the precise cause without a thorough review, consulting a birth injury attorney is the best way to determine if medical negligence played a role. An experienced attorney can evaluate the specifics of the birth and the medical care provided and advise you of your potential legal options.

Introduction to Autonomous Robots
A robot that not only can maintain its own stability as it moves, but also can plan its movements.
Nasa's K10 (Autonomy and robotics):
Autonomous robots are smart machines that can work on their own, figuring out what is going on around them, making decisions, and acting without help from a person.
An autonomous robot is a type of robot that has a lot of freedom and can do things on its own without help from a person.
This is possible because the robot has sensors like cameras, LiDAR, and sonar that let it see and hear what is going on around it.
The robot then takes this information and uses it to make decisions. This gives it the ability to act on its own.
Types of robots
There are many different kinds of robots, and each one has its own strengths and weaknesses. Some of these are:
- Autonomous Robots: As we have already talked about, autonomous robots can work on their own without human help.
- Controlled Robots: To work, controlled robots need input from people. They can be programmed to do specific tasks, but they do not have as much freedom as robots that can do things on their own.
- Semi-Autonomous Robots: These robots have parts of both autonomous and controlled robots, so they can do some tasks on their own but still need some help from humans.
- Automated Robots: These robots are set up to do things on their own.
But they might not be as independent as robots that can do things on their own.
Differences between autonomous robots and other kinds
Autonomous robots are different from other types of robots because they can make decisions and act on their own based on what they see in their environment without needing constant human input.
Even though other kinds of robots can do certain jobs, they do not have as much freedom as autonomous robots.

Components and Technologies for Autonomous Robots
Autonomous robots are smart machines that can work on their own, sense their surroundings, make decisions, and act without help from a person.
To make a robot that can work on its own, it is important to know what parts and technologies are needed.
Hardware components are an important part of making a robot that can do things on its own. Among them are:Actuators, like motors, brakes, and solenoids, make it possible for the robot to move and interact with its surroundings.
- Sensors: Sensors are necessary for the robot to understand its surroundings.
Some examples of sensors include cameras, LiDAR, and inertial measurement units (IMUs).
- Power sources: In order to work, autonomous robots need a reliable power source, like batteries or fuel cells.
- Computing hardware: For the robot to process sensor data, run algorithms, and control actuators, it needs a microcontroller or single-board computer.
When making an autonomous robot, software is just as important as hardware. Among them are:
- Perception algorithms: Perception algorithms let the robot interpret data from its sensors and figure out what is going on around it.
- Localization algorithms help the robot figure out where it is and which way it is facing in its environment.
- Mapping algorithms make a model of the environment that the robot can use to plan its movements.
- Planning and control algorithms: Planning and control algorithms let the robot move around and interact with things in its environment.
For the robot to work well, it needs to be able to talk to its surroundings. This includes talking to other devices and systems, either wirelessly or by using wires.
To make a robot that works on its own, you need to know a lot about mechanical engineering, electrical engineering, computer science, and robotics.
The Importance of Sensors in Autonomous Robots

The Record-Time FDA Approval that Almost Didn’t Happen.
For the more than 7 million Americans who inject insulin, Friday will mark an important anniversary: 38 years since the Food and Drug Administration (FDA) approved the use of human insulin synthesized in genetically engineered bacteria. This momentous event launched a revolutionary new era in pharmaceutical development, and, as the FDA medical reviewer of the product and the head of the evaluation team at the time, I had a front-row seat. To commemorate the event, I open a bottle of champagne every year.
The saga is remarkable in several ways, not least of which is that, although both the drugmakers and regulators were exploring unknown territory, the development of the drug and its regulatory review progressed rapidly for its day—at “warp speed,” so to speak.
When insulin in crude form was first produced in 1922 by Canadian researchers Frederick Banting and Charles Best, it lifted what had effectively been a death sentence imposed on anyone diagnosed with diabetes. Type 1—insulin-requiring—diabetes occurs because the insulin-producing cells of the pancreas, beta cells, are damaged and make little or no insulin, so sugar can’t get into the body’s cells for use as energy. People with Type 1 diabetes must use insulin injections to control their blood glucose, or their blood sugar rises to dangerous levels, leading to coma and death.
By the end of that year, the drug company Eli Lilly and Company had devised a method for much higher purification of this kind of crude insulin harvested from animal pancreases. (Founded in 1876 and still in operation, Eli Lilly was most recently in the news for its COVID-19 therapeutics efforts.) Over the next half-century or so, thanks to the process Lilly perfected, the insulins obtained from pig or cow pancreases (which differ slightly in chemical composition from human insulin) were improved continuously in purity, and were formulated in ways that refined their performance once injected into human patients.
During the early 1970′s, as the supply of animal pancreases declined, and the number of insulin-requiring diabetics grew, there were widespread fears of possible future shortages of insulin. Fortuitously, around the same time, a new and powerful tool—recombinant DNA technology, also known as “genetic engineering,” or “genetic modification”—became available and offered the promise of unlimited amounts of insulin that was identical to the molecule produced by humans.
That tool went on to become one of drug development’s greatest success stories, but not without some regulatory growing pains, and no thanks to the Monday-morning quarterbacking from politicians and pundits that often colors how FDA officials approach their work.
THE BIRTH OF BIOPHARMACEUTICALS
In 1973, the seminal molecular genetic engineering experiment was reported in a research article by academic scientists Stanley Cohen, Herbert Boyer, and their collaborators. These scientists had isolated a ringlet of DNA, called a “plasmid,” from a bacterium, and used certain enzymes to splice a gene from another bacterium into that plasmid. They then introduced the resulting “recombinant,” or chimeric, DNA into E. coli bacteria.
When these now “recombinant” bacteria reproduced, the plasmids containing the foreign DNA were likewise propagated, producing amplified amounts of the functional recombinant DNA. And, because DNA contains the genetic code that directs the synthesis of proteins, this new methodology promised the ability to induce genetically modified bacteria (or other cells) to synthesize desired proteins in large amounts. In other words, such genetically modified microorganisms could be programmed to become mini-factories, producing high-value proteins of all sorts.
The scientists at the Eli Lilly Company immediately saw the promise of this technology, most especially for the production of unlimited quantities of human insulin in bacteria grown at huge scale. After obtaining the genetically engineered human-insulin-producing E. coli bacteria from a startup, Genentech, Inc., Lilly developed processes for the large-scale cultivation of the organism (in huge fermenters, similar to those that make wine or beer), and for the purification and formulation of the insulin.
Insulins had long been Lilly’s flagship products, and the company’s formidable expertise was evident in the purification, laboratory testing, and clinical trials of the laboratory-made human insulin. Lilly’s scientists painstakingly verified that their product was extremely pure and identical in composition to human pancreatic insulin (which, again, differs slightly from beef and pork insulin—all that was available to diabetics up to that time).
Lilly began clinical trials of its human insulin in July 1980, and the product performed superbly. There were no systematic problems with treating “naive” patients (those who had never before received injections of animal insulin) or with those who were switched from animal to human insulin. Even more promisingly, a small number of patients who had had adverse reactions of some kind to the animal insulins, such as redness or swelling at the injection site or (rarely) allergic reactions to specific animal proteins contaminating the insulin, tolerated the human insulin well.
The dossier that provided evidence of safety and efficacy was submitted in May 1982 to the FDA, where I was the medical reviewer and head of the evaluation team at the time. Those were the days before electronic submissions, so the submission looked sort of like this, only several times larger:
Over many years, the FDA had had prodigious experience with animal-derived insulins, and also with drugs derived from various microorganisms, so it was decided that no fundamentally new regulatory paradigms were necessary to evaluate the recombinant human insulin.
In other words, recombinant DNA techniques were viewed as an extension, or refinement, of long-used and familiar methods for making drugs. That proved to be an historic, precedent-setting decision.
SYSTEMIC RISK-AVERSION IN DRUG OVERSIGHT
Based on my team’s exhaustive review of Lilly’s data, which were obtained from pre-clinical testing in animals, and from clinical trials in thousands of diabetics, the FDA granted marketing approval (permission to begin selling the product) for genetically engineered, or recombinant, human insulin (Humulin®) on October 30, 1982. The review and approval took only five months, despite the fact that the agency’s average approval time for new drugs then was 30.5 months. In retrospect, that rapid approval was particularly remarkable for a drug that was produced with a revolutionary new technology, and one that would be available in pharmacies nationwide to millions of American diabetics after its approval.
What happened behind the scenes is revealing. My team and I were ready to recommend approval after just four months’ review. But when I took the packet to my supervisor, he said, “Four months? No way! If anything goes wrong with this product down the road, people will say we rushed it, and we’ll be toast.” Unfortunately, that’s the bureaucratic mindset. Former FDA Commissioner Alexander Schmidt aptly summarized the regulator’s conundrum thusly: “In all our FDA history, we are unable to find a single instance where a Congressional committee investigated the failure of FDA to approve a new drug. But the times when hearings have been held to criticize our approval of a new drug have been so frequent that we have not been able to count them. The message to FDA staff could not be clearer.” In other words, bureaucratic risk-aversion isn’t guided by valid risk-benefit concerns, but by a fear of Monday-morning quarterbacking from politicians and pundits who know little about the complex process of drug development and capitalize on and fan the public’s anxieties to further their own agendas.
My former colleague, Economics Nobel Laureate Milton Friedman, spoke to the principle more generally, counseling that to understand the motivation of an individual or organization, you need to “follow the self-interest”—and a large part of regulators’ self-interest lies in staying out of trouble. That means staying out of the crosshairs of politicians itching for a scandal.
I don’t know how long my supervisor, who perceived there were potential hazards in a record-time approval, would have delayed his sign-off, but when he went on vacation a month later, I took the packet to his boss, the division director, and he approved it. I was tasked to call the head of regulatory affairs at Eli Lilly to inform him of the approval and, when I broke the news, there was a long, unbroken silence on his end. Finally, I said, “Hello, are you still there?” and he answered, “I’m waiting for the other shoe to drop.” Well, there was no “other shoe,” but it’s telling that the timing of the approval took even the company planners by surprise, and it was many months until Humulin was widely available in pharmacies.
The approval of Humulin had significant ramifications. A New York Times article quoted my prediction that the speedy approval constituted a major step forward in the “scientific and commercial viability” of recombinant DNA technology. “We have now come of age,” I said at the time, and potential investors and entrepreneurs agreed. Seeing that genetically engineered drugs, or “biopharmaceuticals,” would compete with other medicines on a level playing field without unwarranted regulatory obstacles, the “biotechnology industry” was on the fast track. And, indeed, as of 2019, eight of the 10 top-selling drugs in the U.S. were made with genetic engineering techniques.
Unfortunately, despite what it achieved for drug producers, the rapid approval of human insulin did not begin a trend among drug regulators. Even with a toolbox of improved technologies available to both the FDA and industry, bringing a new drug to market now usually takes 8-12 years, and costs, on average, over $2.5 billion. Regulators continue to be highly risk-averse, few new drugs are approved without convening extramural advisory committees, and decisions are still sometimes hijacked by political forces outside the FDA (such as we’ve seen with recent pressure on the FDA to approve products related to COVID-19 testing or therapeutics prematurely).
Other FDA-regulated biotechnology sectors have fared far worse than human drugs. For instance, regulators have made a colossal mess of the regulation of genetically engineered animals, which FDA chose to regulate as “new animal drugs.” Some of its most significant missteps include an excruciatingly prolonged, 20-plus year review of a faster-growing Atlantic salmon, and an abortive flirtation with genetically engineered mosquitoes to control mosquitoes that carry viral diseases. (It took FDA more than five years to realize that the latter were actually pesticides, and that jurisdiction should be turfed to EPA.) Regulation of genetically engineered animals hasn’t aged as gracefully as genetic engineering technology itself; as a result, the entire biotechnology sector of genetically engineered animals is moribund.
FDA’s oversight—which encompasses a broad spectrum of food, drugs, medical devices and tobacco products worth more than $2.6 trillion, about 20 cents of every dollar spent by U.S. consumers—is, overall, too risk-averse, defensive, and bureaucratically top-heavy.
Regulators need to recall the “bargain” that society has made with them: civil servants have lifetime tenure and are protected from political pressure and retaliation, in return for which they are supposed to make decisions based solely on the public interest—without fear or favor. To get FDA-regulated products to those of us who need them, Congressional oversight and public opinion must create a healthier, more constructive balance. | <urn:uuid:a5d3d7b0-878f-42a3-a179-69727084b137> | CC-MAIN-2024-51 | https://medecon.org/the-record-time-fda-approval-that-almost-didnt-happen/ | 2024-12-05T19:09:20Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066362401.69/warc/CC-MAIN-20241205180803-20241205210803-00100.warc.gz | en | 0.966747 | 2,492 | 2.8125 | 3 |
The recent furor over proposed amendments to B.C.’s Land Act centres around “consent,” specifically, the super-charged “free, prior, and informed” form of “consent.”
The B.C.’s NDP government recently cancelled consultation into planned legislation that would give First Nations joint statutory decision-making on land use after the proposal met with public outcry and opposition from BC United and the BC Conservative Party. But the topic is going to crop up again, especially during the coming provincial election campaign. Even if the New Democrats would prefer to ignore the whole imbroglio until after Oct. 19.
The burning question that generated such vociferous resistance is the one the B.C. government attempted to avoid, and continues to deny. Do the amendment changes giving First Nations statutory decision-making on land use constitute a veto power?
The ordinary meaning of the word “consent” would suggest “yes.” The supercharged “free, prior, and informed” version would scream, “hell, yes.”
The website thesaurus.com lists “veto” as among the strongest opposites of consent (along with the likes of denial, refusal, and rejection).
The meaning of consent can also include “acquiescence,” which sounds like caving in. Acquiesce can mean “to assent tacitly,” or “submit or comply silently or without protest.” Neither of those things are what First Nations have in mind, which is where “free, prior and informed” comes in.
Is withholding consent a veto by another name?
As defenders of the consent requirement point out, the United Nations Declaration of the Rights of Indigenous Peoples (UNDRIP) does not use the exact word “veto.” On the other hand, it’s pretty obvious that the requirement for consent will necessarily involve occasions where an Indigenous governing body withholds consent.
“Consent ‘must include the option of withholding consent.’ This conclusion clearly makes sense. It would be absurd to conclude that Indigenous peoples have the right to say ‘yes’, but not the right to say ‘no’ – even in the most damaging circumstances,” writes Ontario/Quebec lawyer Paul Joffe, a specialist in Indigenous rights.
Then again, Joffe also notes, “‘Veto’ implies an absolute power, with no balancing of rights. This is neither the intent nor interpretation of the UN Declaration, which includes some of the most comprehensive balancing provisions in any international human rights instrument.”
UNDRIP balancing provisions prevent veto
Defenders of the proposed Land Act changes make similar arguments. They say changes are based on B.C.’s Declaration of the Rights of Indigenous Peoples Act, which in turn is based on UNDRIP. In fact, it says right in DRIPA that one of its purposes is “to affirm the application of the [UN] Declaration to the laws of British Columbia.”
Most of DRIPA’s wording is actually a cut-and-paste of UNDRIP, which is embedded as a schedule to the B.C. law.
It would have been very helpful for defenders of DRIPA, and its application to the Land Act, to outline the UNDRIP balancing provisions that prevent the “right to say no” from becoming an absolute veto.
They are right there in plain sight at the end of UNDRIP in Article 46 (1): “Nothing in this Declaration may be interpreted as implying for any State, people, group or person any right to engage in any activity or to perform any act contrary to the Charter of the United Nations or construed as authorizing or encouraging any action which would dismember or impair, totally or in part, the territorial integrity or political unity of sovereign and independent States.”
It makes perfect sense that the United Nations, whose members are sovereign states, would be keen to protect “the territorial integrity” and “political unity” of its member states.
Exactly what “political unity” of a sovereign state means, however, is as open to interpretation as the word “veto.” And it may be the political unity that fueled the passage of DRIPA has shattered because of differing interpretations of both.
Courts may decide impasse
An outline of the proposed changes states emphatically that “Agreements do not provide a ‘veto’ and require due process.” It also references B.C.’s DRIPA “as the framework for implementing” UNDRIP.
The proposed Land Act changes also note that anyone “affected by decisions made under joint or consent-based agreements will continue to be able to seek review of the decision by the courts.” It’s not clear from that wording if anyone can seek such a review where consent isn’t granted.
It’s also far from clear what happens in cases, which are bound to arise, where consent is required from multiple First Nations and at least one of those First Nations withholds consent.
Often the courts end up deciding these types of impasses.
No veto in UNDRIP
“To look at the issue from the Crown or project proponent perspective, the fact that Indigenous groups have ‘no veto’ does not mean that the project will necessary go ahead. The Court will determine whether the procedural and substantive standards have been met,” wrote Shin Imai of York University’s Osgoode Hall Law School in a 2017 paper.
Conversely, West Coast Environmental Law pointed out, “Again and again, the Canadian courts have encouraged the Crown to negotiate its way out of this mess, rather than battling it out in the courts” and “a ‘veto,’ where one party simply blocks a decision without working with the other, is not a feature of joint decision-making, but a failure.”
Interestingly, “joint decision-making,” like “veto,” doesn’t appear anywhere in UNDRIP. In fact, the word “joint” doesn’t show up in UNDRIP at all. Instead, “Indigenous peoples have the right to participate in decision-making in matters which would affect their rights … as well as to maintain and develop their own indigenous decision-making institutions.”
Stuck in semantic purgatory
DRIPA’s section 7, entitled, “Decision-making agreements,” leaves open the prospect of “the exercise of a statutory power of decision jointly by (i) the Indigenous governing body, and (ii) the government or another decision-maker.”
That sounds like an option for the government to override part B of section 7, which requires “the consent of the Indigenous governing body.”
Or does it? If the parties can’t reach a joint decision AND an Indigenous governing body doesn’t consent, what is that?
It’s not a “yes,” that’s for sure. And it’s not a “no” if no means “veto.”
It sounds stuck in a semantic purgatory or lost somewhere in Humpty Dumpty territory: “When I use a word, it means just what I choose it to mean — neither more nor less.”
Veto a touchy topic
Along the way, veto has become a touchy word, verging on taboo.
The Union of BC Indian Chiefs posted about “the lazy and incoherent conflation of ‘consent’ and ‘veto.’” However, the Indigenous Environmental Network felt free to conflate: “While companies should set Free, Prior, and Informed Consent as an ideal standard, only Indigenous communities have the right to a project veto.”
So, we’re back to the original beefs about the proposed B.C. Land Act changes. Does the refusal to consent — which is an obvious potential outcome if consent is required — represent a veto? Does it matter?
Meanings of “veto” include “to prohibit emphatically.”
West Coast Environmental Law says, “Legally the word veto refers to situations where a chief executive, typically a president or a monarch, has the legal authority to unilaterally reject a law or proposal from a law-making body like a legislature.” Leaving aside the notion that a First Nations chief is a “chief executive,” that’s a narrow definition of “veto.”
A dictionary.com definition describes “veto” as “the right of one branch of government to reject or prohibit a decision of another branch.”
The Law.com dictionary doesn’t offer a meaning for veto. But it defines consent as a voluntary agreement to another’s proposition.
Putting veto aside, everyone agrees consent is required.
No could mean no, maybe or yes
When we think of consent in sexual relations, the phrase “no means no” is a hard no. “Free, prior and informed” is baked into sexual consent. That’s not the “acquiescence” form of consent, which has an air of “no that could mean yes” about it.
In other contexts, such as engagements with First Nations, the expression “free, prior and informed” is needed to create a straitjacket of meaning around “consent.” The straitjacket transforms “consent” into an expression that if it isn’t precisely cognate with “veto” certainly quacks like it.
“Free” would mean free of acquiescence, cajoling, seduction, inducement, coercion, nudging, bribery, etc. “Prior” would negate the hallowed principle of “better to ask forgiveness than seek permission.” And “informed” flips the onus from “buyer beware” to a requirement for transparency.
Of course, the legal meanings of words don’t always jive with their ordinary applications. That’s true even if a law firm specializing in Indigenous law was among the first to argue that the consent within proposed Land Act changes amounts to a veto.
“Under the amendments being proposed by the B.C. government, changes will be made to enable agreements with Indigenous groups such that they will be provided a veto power over decision-making about Crown land tenures and/or have ‘joint’ decision making power with the Minister,” stated a Jan. 24 posting on the website of McMillan LLP.
“Where such agreements apply, the Crown alone will no longer have the power to make the decisions about Crown land that it considers to be in the public interest,” the McMillan bulletin noted.
Does Crown have power to make decisions in public interest?
West Coast Environmental Law agreed, but said it “must be understood against the shameful and harmful legacy of impacts of unilateral Crown decision-making on First Nations peoples and territories over the past 150 plus years.”
However, if the Crown (read sovereign B.C. government) has no power to make decisions in the public interest, does that mean section 46 of UNDRIP doesn’t provide the balance scholars like Joffe insist it does? Would that not be an impairment of the territorial integrity or political unity of the sovereign entity of B.C.?
Political columnist Vaughn Palmer of the Vancouver Sun opened up this can of worms when he pointed out the NDP government had “quietly launched public consultation” on changes to the Land Act. “The ministry did not publicize the invitation with a news release, suggesting the government is not all that keen to attract attention to the exercise,” Palmer opined.
That touched off the imbroglio, which included attacks on the process of consultation and the proposed amendments themselves from Opposition leader Kevin Falcon of BC United and John Rustad, B.C. Conservative leader, who both voted in favour of DRIPA as MLAs when they belonged to the BC Liberal Party (now the BC United).
BC government ‘put First Nations in the middle unnecessarily’
BC Green Party MLA Adam Olsen, a member of the Tsartlip First Nation slammed both leaders for what he perceived as the hypocrisy of supporting DRIPA but not the Land Act changes. Olsen also criticized the NDP, Lands Minister Nathan Cullen in particular, for their clumsy handling of the consultation process, which “put First Nations in the middle unnecessarily,” according to one of Palmer’s follow up columns.
While Cullen issued a mea culpa when he announced government was suspending its public consultation of the Land Act and pressing pause on new legislation, he took a swipe at critics for their “dog whistles.” That definitely missed the point. It’s possible to support DRIPA and also criticize the government for its handling of the consultation. If the government wasn’t being a little sneaky about it, it was at least incompetent. Times Colonist columnist Les Leyne wondered how Cullen was able to hang on to his cabinet post after the whole sorry episode.
Whenever consultations on changes to the Land Act reopen, whoever is in charge should point explicitly to the parts of B.C.’s DRIPA that show First Nations don’t really have a veto. Unless their actual intention is to give them a veto, which would go beyond section 7 and the last article of UNDRIP.
“Indigenous rights may be subject to limitations or lawful infringement, based on strict criteria that can be objectively determined,” noted Joffe, referencing the article in UNDRIP on limitations being “non-discriminatory and strictly necessary solely for the purpose of securing due recognition and respect for the rights and freedoms of others and for meeting the just and most compelling requirements of a democratic society.”
Ultimately, it’s up to the B.C. government to come clean, acknowledge the genuine confusion, and resolve the duality of intention. Otherwise the courts will decide. | <urn:uuid:08bea657-4f1c-4126-9c8a-a0fe06d77f5c> | CC-MAIN-2024-51 | https://northernbeat.ca/opinion/veto-or-consent-controversy-land-act/ | 2024-12-05T18:12:28Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066362401.69/warc/CC-MAIN-20241205180803-20241205210803-00100.warc.gz | en | 0.945877 | 3,025 | 2.703125 | 3 |
Visual effects have long played a crucial role in enriching the gaming experience, transforming virtual worlds into immersive landscapes filled with beauty and realism. One such effect, known as “bloom,” has both fascinated and divided gamers and game designers alike.
Whether you adore its ethereal glow or find it distracting, bloom remains a potent tool in the game developer’s arsenal.
The Origin of the Term Bloom
The term “bloom” predates its application in video games, with roots in photography and filmography. In these traditional media forms, bloom refers to the visual effect where light appears to extend beyond its natural borders, creating a sort of ethereal glow.
How did this concept migrate into the domain of video games, and what significance does it carry today? To answer these questions, we shall trace the history and evolution of the term in the broader context of visual arts and technology.
From Camera Lens to Computer Screen
Originally, the bloom effect was an optical phenomenon observed in camera lenses. It occurred when a bright light source was captured, causing a halo or glow to spread beyond the confines of the light’s actual boundary.
This was often the result of imperfections in the lens or the film but later became a deliberate artistic choice in photography.
The Leap to Digital Media
As technology advanced, so did the techniques used to create visual effects in digital media. The realm of computer graphics and visual effects started to adopt the term “bloom” to describe a similar glowing effect.
This adaptation marked a significant moment as the term transcended its traditional boundaries and found a home in digital artistry.
The Evolution in Video Games
Video games, being a form of digital media, naturally adopted bloom as part of their visual effects toolbox. The transition was not just a technological leap but also an aesthetic one.
Game designers recognized the potential of bloom to enhance not just the realism but also the mood and atmosphere of a game. By the late 1990s and early 2000s, bloom was making its way into various game engines, becoming a staple in AAA titles as well as indie games.
Criticisms and Adoption
While the bloom effect has been widely adopted, it has not been without its critics. Some argue that excessive use of bloom can lead to visual clutter, making it hard to focus on gameplay elements.
Despite these criticisms, the effect has found a place in the toolbox of game developers aiming for a certain aesthetic or emotional impact.
Cultural Impact and Beyond
The concept of bloom has not just remained a technical term but has also entered popular gaming culture. Gamers often discuss the use or misuse of bloom in forums and social media, reflecting its impact on player experience.
As gaming evolves, so does the application and perception of bloom, making it a continually relevant topic in game design.
Technical Aspects of Bloom
Implementing bloom in video games requires a nuanced blend of art and technology. Both game designers and engineers contribute to this visual effect, which has a notable impact on the game’s overall look and feel.
Whether it’s the vibrant sunset in an open-world game or the eerie glow of a sci-fi landscape, bloom helps to create these visual experiences.
Algorithms Behind the Glow
The basic idea of bloom in games is to simulate the way light interacts with a camera lens or the human eye. Algorithms play a crucial role in replicating this effect.
Typically, a two-step process is followed—first, bright pixels are isolated from the scene, and then these are blurred to create a halo or glow effect. Gaussian or Box blur algorithms are commonly used for this purpose.
Shaders at Work
In game development, shaders are specialized programs that run on a graphic card’s GPU to manage how the pixels on the screen look. Shaders are instrumental in implementing the bloom effect.
Essentially, they manipulate the pixel values in real-time to generate the intended visual effects. For bloom, fragment shaders are often used to execute the algorithms that control how the glow appears and integrates into the overall scene.
High Dynamic Range and Bloom
High Dynamic Range (HDR) is another essential factor in achieving realistic bloom effects. HDR allows for a greater range of luminance levels between the darkest and the brightest parts of an image.
In the context of bloom, HDR enables the effect to interact more naturally with other lighting conditions and materials in the game, offering a more lifelike appearance.
Introducing bloom into a game isn’t just a simple flick of a switch; it has implications for the game’s performance. The computational cost of running complex algorithms and shaders can be high, making optimization a key consideration.
Techniques like down-sampling and using lower-resolution textures are common practices to make the effect more manageable for different types of hardware.
Variations and Customization
Bloom is not a one-size-fits-all solution; it can be adjusted and customized to suit the unique requirements of each game. Parameters such as intensity, threshold, and radius can be tuned to change the look and feel of the bloom effect, allowing for a wide range of artistic possibilities.
The Aesthetics of Bloom
Visual effects like bloom are not merely technical achievements; they also serve as expressive tools that contribute to a game’s overall aesthetic and emotional impact. Bloom can transform a scene from ordinary to captivating, imbuing it with a certain atmosphere or mood.
Atmosphere and Mood Enhancement
Bloom is often employed to generate specific atmospheres or moods within a game. A soft glow around a light source can evoke feelings of warmth and coziness, while an intense, radiant bloom can create a sense of surrealism or even otherworldliness.
By manipulating the subtleties of the effect, game designers can guide the emotional response of the player.
Case Studies of Effective Use
Numerous games have effectively employed bloom to enhance their storytelling and aesthetic appeal. Titles like “The Legend of Zelda: Breath of the Wild” use bloom to make natural landscapes more enchanting, while games like “BioShock” use it to instill a sense of decay and nostalgia.
These examples demonstrate the wide range of applications and the versatility of bloom as an artistic tool.
When Less Is More
It’s important to acknowledge that bloom is not universally beneficial to all types of games or scenes. In fast-paced action games, excessive bloom can obscure critical gameplay elements, making it harder for players to make rapid decisions.
Similarly, in horror games, too much bloom might counteract the intended dark and claustrophobic atmosphere.
Controversies and Criticisms
Bloom has been the subject of debate within both the game development and player communities. Critics often point out that when overused, bloom can lead to visual confusion, making it difficult to distinguish between important and non-important elements in a scene.
This can result in a lack of clarity and focus, ultimately detracting from the player’s experience.
Artistic Versus Realistic Intent
The application of bloom can be divided into two major intent categories: artistic and realistic. In some games, bloom is used to mimic the way cameras or eyes would capture bright light, striving for a more lifelike presentation.
In others, it serves a purely artistic function, amplifying certain emotions or artistic themes without concern for realism. Both approaches have their merits and challenges, making the choice highly dependent on the specific goals of the game.
Bloom and Gameplay
While the aesthetic and emotional impacts of bloom are often discussed, its effect on gameplay mechanics is equally worthy of attention. The bloom effect can serve as more than just a visual ornament; it can also directly influence how players interact with and experience a game.
Signposting and Cues
Bloom can be used as a gameplay mechanic to direct players toward specific objectives or important items. For example, the subtle glow around a crucial object can draw a player’s attention, guiding them towards interaction.
This technique can be particularly useful in complex environments where visual cues help in distinguishing important elements.
Emotional and Psychological Impact on Gameplay
Bloom can also influence a player’s psychological state during gameplay. The use of bloom to create a serene environment might encourage exploration, while an intense glow in a horror setting can add to the suspense and tension.
The ability to manipulate player psychology through visual effects like bloom is an advanced design strategy with profound implications.
While bloom can enhance gameplay experience, it also raises accessibility issues. Players with visual impairments or sensitivity to bright lights may find games with heavy use of bloom challenging or even unplayable.
Therefore, offering options to adjust or disable the bloom effect can be an important feature for inclusive game design.
Interaction with Other Game Mechanics
Bloom doesn’t exist in a vacuum; it interacts with other game mechanics and systems. For instance, in stealth-based games, the bloom effect around light sources can be an integral part of the gameplay, indicating areas where the player character is more likely to be detected.
Understanding how bloom interacts with other elements is essential for cohesive game design.
Performance Implications on Gameplay
Implementing bloom comes with computational costs that can affect a game’s performance, particularly on lower-end systems. Frame rate drops can impair gameplay experience, making fast-paced action or precise timing more difficult for the player.
Game developers need to weigh the aesthetic and gameplay benefits of bloom against the potential for performance issues.
The Impact on Hardware and Performance
While the visual allure of bloom effects in games is often well-received, its impact on hardware and performance cannot be overlooked. From powerful gaming rigs to budget laptops, the range of hardware configurations is vast.
It’s essential for game developers to consider how bloom affects the overall performance across these varied systems.
Computational Cost of Bloom
Implementing bloom typically involves multiple rendering passes, each contributing to the computational workload. Techniques like HDR rendering, Gaussian blurring, and layer blending are computationally expensive operations.
They often require high memory bandwidth and substantial GPU cycles, especially in games with complex environments and multiple light sources.
Scaling Across Hardware Configurations
One of the challenges in implementing bloom is ensuring that the game remains playable across a wide array of hardware configurations. High-end gaming systems may handle bloom effects effortlessly, but the same cannot be said for older or budget hardware.
In such cases, frame rates may suffer, compromising the overall gameplay experience.
Dynamic Adjustment Techniques
Some games employ dynamic adjustment techniques to manage performance. In essence, the quality of the bloom effect is adjusted in real-time based on the available system resources.
For instance, when the system is under high load, the game might automatically reduce the quality of the bloom effect to maintain a steady frame rate.
User Control and Customization
Providing users with the option to adjust the bloom effect can also be a sound strategy to tackle performance issues. This not only allows players to customize their visual experience but also enables them to find a balance between visual quality and performance that suits their hardware.
Optimization Strategies for Developers
Game developers can adopt several optimization strategies to make bloom more performance-friendly. Techniques such as down-sampling the bloom effect or employing simpler algorithms can help in reducing the computational load.
Moreover, some games choose to disable bloom entirely during fast-paced action scenes where high frame rates are crucial.
Bloom effects in video games serve a multifunctional role, contributing to both aesthetics and gameplay mechanics. While visually captivating, the technique demands careful consideration due to its impact on hardware performance and its potential to alter player behavior.
Balancing the artistic and functional attributes of bloom requires a nuanced approach, particularly in light of its implications for game accessibility and system requirements. Whether used to guide players, elicit specific emotional responses, or simply to enhance visual appeal, bloom remains a compelling tool in game design.
Its effectiveness, however, hinges on judicious application and thoughtful optimization. | <urn:uuid:b1f9ac59-ca78-402b-8cd3-664b18698ed5> | CC-MAIN-2024-51 | https://techreviewadvisor.com/what-is-bloom-in-games/ | 2024-12-05T20:04:06Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066362401.69/warc/CC-MAIN-20241205180803-20241205210803-00100.warc.gz | en | 0.927453 | 2,486 | 2.9375 | 3 |
Seamus Heaney, considered by many to be the greatest Irish poet since William B. Yeats, texted his wife Marie a few hours before his death: “Do not be afraid!” How comforting these words were to her I do not know. They seem, however, appropriate words for a man who faced so many crises in his life, dealt with them with grace, dignity and humility and “kept going.” His poetry gives mankind helpful guides in confronting the mysteries and difficulties of this world and urges us to do the same.
In her introduction to Seamus Heaney, Helen Vendler, a close friend, states that his poetry “reached a large public in Ireland and abroad and that public extends to all classes.” She explains that it is in his poetry by which the reader can recognize family situations, beautiful landscapes and social concerns. It is also autobiographical starting from his childhood, covering the states of growth and adulthood, and taking him into his 60s. In his poems, the reader sees images of him at home with his parents, siblings and relatives, “an adolescence with school fellows and friends, adulthood with marriage and children, a displacement from Northern Ireland, travels, sorrows and deaths . . .” The global influence of Heaney’s words extends to classrooms throughout the world.
Tom Deignan, a high school teacher in Brooklyn, New York, and a columnist for the Irish Voice, states that Seamus Heaney’s poem, “Digging” has “played a central role in my teaching.” He teaches it the first week of classes and it has the same important message for his students that Heaney sent to his wife: “Do not be afraid!”
At first, the students are confused by the poem as it begins with agricultural imagery with which they are not familiar. But when the “I” narrator states that his pen fits his hand as snug as a gun, he has gotten their attention. Guns are familiar to these kids, and eventually they see the “power” of the pen contrasted with the “power” of the gun. The narrator describes his father Stooping in rhythm through potato drills/ Where he was digging… and he notices … the old man could handle a spade [this world also gets the kids’ attention]/ Just like his old man. Deignan explains that the poem becomes a “multi-generational poem” and leads to discussions of the students’ parental relationships and the generations that came before them.
At the conclusion of the poem, the narrator states, I’ve no spade to follow men like them/ Between my finger and my thumb/ The squat pen rests/ I’ll dig with it. The students begin to see the relationship to their own lives and wonder what this “farm boy” knows about guns. Deignan then tells them a bit about Irish history and has them “dig” into their own histories.
Seamus Heaney was born on April 13, 1939, in Bellaghy, County Derry, at the family home, Mossbawn, the eldest of nine children. His first poems describe the experiences of childhood, “which could be the experiences of any child growing up on a farm and watching daily and seasonal rituals of churning, haymaking and turf cutting.” (Stepping Stones, Interviews with Seamus Heaney, by Dennis O’Driscoll).
These poems and recollections make up the core of his first two books, Death of a Naturalist (1966) and Door into the Dark (1969). Helen Vendler states that Heaney had an awareness of words and their importance, even to his own name and group names that he heard regularly: “Catholics,” “farmers,” “Seamus” and the “Heaneys:” … the child hides in the hollow tree/ he hears the family calling his first name…You can hear them/ draw the poles of stiles/As they approach/ calling you out (“Mossbawn”). Ironically, Heaney himself told Dennis O’Driscoll there was no great significance to his parents’ choice of his name! He said his mother did not “lean toward the Gaelic side of things.”
There is a mystical quality to these poems in that the narrator begins to see himself more as a “tree spirit” than a human child: … small mouth and ear/ in a woody cleft/ lobe and larynx/ of the mossy places (“Oracle”). In another poem, “Alphabeles,” the child’s recognition that he is more than “Seamus,” that he is one of a circle of kin sharing his surname. He watches with delight as the man who is plastering his house writes his family name: All agog at the plasterer on his ladder/Shimming our gable and writing our name there/ . . . letter by strange letter . . . .
These references to his name and family led Heaney to wonder about his identity as a poet. Should he write as a child and family member or as an adult with his own identity? Should he be a spokesman for Catholicism or a transmitter of an Irish literary tradition? Eventually he became confident and comfortable, believing that he does not have to speak for any particular group or point of view. He can be himself and express his ideas as life unfolds before him. And let the world listen and respond! Other poems in Death of a Naturalist describe a variety of emotions as the child grows: conquering a fear of death (“An Advancement of Leaving”), shrugging shoulders at the sight of drowning puppies (“Follower”) and the anxiety of a son succeeding his father (“Ancestral Photographs”).
A terrible tragedy for Heaney and his family was the death of his younger brother Christopher, aged four, who was struck by a car near their home. Seamus was 14 and away at school in Derry. He deals with this in “Mid-Term Break.” The first person narrator has been called home from school for the wake and burial. A neighbor (“Big Jim Evans”) is named but not the speaker or the dead child. It seems the speaker’s tone is one of anger, shock and irritation; all of it is overwhelming: I was embarrassed/ By old men standing up to shake my hand/ And tell me they were “sorry for my trouble”/ Whispers informed strangers I was the eldest/ Away at school… Next morning I went up into the room… I saw him/ For the first time in six weeks. Paler now…Wearing a poppy bruise on his left temple/ He lay in his four foot box as in his cot.
The words of the strangers he seems to interpret as a reproach, insinuating if he were at home, this might not have happened. When he sees the corpse, the images of snowdrops and candles suggest a sense of peace may come to him, but then the poppy bruise brings back the horror of the accident and the sight of his brother in the coffin heightens his emotions.
Much of Seamus Heaney’s poetry deals with the conflict in Northern Ireland. In 1969 the British sent troops into Belfast and Derry, and in 1972 paratroopers killed 13 unarmed civil rights marchers and wounded 12. This incident is known as “Bloody Sunday.”
Seamus was involved in protests in Newry, and it is in this year he moves his family to County Wicklow in the Republic. He still went back and forth to his family in Derry, and one can see in his collection of poems North how the violence of this period affected him and the people living through it.

In Part I of “Funeral Rights,” the “I” narrator provides images of the victims of the violence, both individual and families, showing how lives were changed forever: I shouldered a kind of manhood. Stepping in to lift coffins… I knelt courteously/ admiring it all/ to the women hovering behind me/ And always in a corner/ the coffin lid/ its nail-heads dressed/ with little gleaming crosses. The narrator’s anger is expressed ironically with words and phrases, such as admiring and gleaming crosses.
In Part II, the theme of the poem is raised to county, country and universal levels: Now as news comes in/ of each neighborly murder/ … a cortege winding past/ each blinded home/ … the great chambers of Boyne/ prepare a sepulchre/ the whole country tunes to the muffled drumming.
In the poems “Ocean’s Love to Ireland” and “Act of Union,” Heaney portrays the English colonization of Ireland as an act of “violent sexual conquest” (The Poetry of Seamus Heaney, A Critical Guide, edited by Harold Bloom). Raleigh has backed the maid to a tree/ And drives inland/ Till all her strands are breathless/ The ruined maid complains in Irish/ … (“Ocean’s Love of Ireland”).
In “Act of Union,” Heaney uses the sonnet form, which we usually associate with love poetry to construct a sexual union that is violent with possible rape connotations. He employs a sexual vocabulary to enhance the imagery: … a bog burst/ a gash breaking open/ the ferny bed…. The persona in the poem is a personification of both England and Ireland, and it is through this persona “that Heaney complicates the nationalist view of colonization as a rape” (Seamus Heaney, A Critical Guide, Oliver Gray). Your back is a firm line of eastern coast/ And arms and legs are thrown beyond gradual hills…. This is Ireland’s geographical location in relation to Britain, with Ireland’s back facing Britain as if she were trying to escape her grasp.
Wintering Oak is a series of “bog” poems that were inspired by the archeological excavations of peat bogs containing preserved human bodies that had been treated like slaves during the Iron Age. Heaney depicts these victims as symbolic of the bloodshed caused by the contemporary violence of Northern Ireland. “As Heaney wrote the ‘bog’ poems, the archeological and contemporary converged more and more. It is the humanity and the contemporaneity of the bog corpse in ‘Punishment’ that has made this the most controversial of Heaney’s archeologies” (Vendler). Heaney makes the archaic, murdered young woman, disinterred in Northern Germany, one of his own ethnic group. She is a sister to the Catholic women whose heads were shaved, and who themselves were tarred for fraternizing with British soldiers. The movement from the past to the present reminds us of the ongoing cruelty of human nature. The frail rigging of her ribs contrasts sharply with her violent death that leaves her also with a shaved head.
In Field Work (1979), Heaney remains outraged at the violence in the North, but he shifts to a more personal tone encompassing a wide range of subjects: love and marriage, mortality and the regenerative powers of “self determination” and the “poetic imagination.” In a 1981 interview, Heaney said that Field Work “was an attempt to try to do something deliberately; to change the note and to lengthen the line and to bring elements of my social self, elements of my usual nature, which is more convivial than most of the poems before that might suggest” (O’Driscoll). Seamus and his family had moved to Glanmore, County Wicklow; their daughter Catherine would be born there. The poet has now changed countries in a political sense, if not a geographical one and comes upon the new scenery and people of the Republic as a “fieldworker” in an alternative culture. Helen Vendler goes on to explain that he is again (after living two years in Belfast) once again living among fields in a rural setting. The work before him is to register the new surroundings and the new feelings and observations it brings, while still keeping that connection to his Northern past.
Heaney begins the collection with six elegies that show his deep feelings about the Northern conflict. One is for his cousin Colum McCartney, who was shot in a sectarian killing. Another for his friend Sean Armstrong, shot by a point blank teatime bullet. The third for the composer Sean O’Riada and the poet Robert Lowell. Next, a friend, Louis O’Neill, a victim of a bomb explosion, and the Catholic poet Francis Ledwidge, killed while fighting for England during the First World War. Work in the field, in this sense, arises from an obligation of survivors to celebrate those who died. In each poem, the individual is characterized and valued (Vendler).
Heaney’s words in the poem “The Strand at Lough Beg” are lurid and shocking. Of his cousin’s death he says:
I turn because the sweeping of your feet/ Has stopped behind me/ To find you on your knees/ With blood and roadside muck in your hair and eyes. One can see Heaney’s ambiguity, between the desire for peace contrasted with the reality of continuing violence. Earlier in the poem, he describes his cousin’s family enjoying their bucolic peace.
His domestic life with his wife, family and social occasions make up the second half of his work. Though there have been earlier poems about his wife and their marriage, his extended treatment of their relationship is found in Field Work. Ten of these poems are called the “Glanmore Sonnets.” Of these the most creative and controversial is “The Skunk.” The poem is a tribute to his wife. He had been teaching in California and greatly missed Marie. The nocturnal visits of a skunk remind him of her. Heaney came in for much criticism (he has been criticized for the lack of more women figures in his poetry) for such a comparison; some saw it as insulting. It is a bit unusual, but readers of the poem will see why it is a magnificent piece of writing.
There are two settings for the poem. The first five stanzas are based on memories of California nights and the last stanza is a recent memory of waiting in bed for his wife to undress. It is a celebration of the energy and freshness of his marriage: … after twelve years I was composing love letters again…. It is also an expression of the pain of separation from her: … the beautiful, useless tang of Eucalyptus spelt your presence…. In the last stanza he reveals how the skunk helped him connect to his wife. There is a sexual connection between his wife in her nightdress and the skunk’s erect tail. In a bedroom scene back in Ireland, Marie bends over naked to pick up her nightdress. Her posture in the darkened room reminds Heaney of the skunk in California. The words glamorous, mysterious and intent suggest a sexual longing and a sexy nightdress. The nightdress is black like the skunk and he uses the word voyeur, which he is, in a sense! He watches his wife prepare for bed, feels a sense of mystery and is stirred by the scene before him.
When I took on this project, I knew very little about Seamus Heaney, having read only a few of his poems. Poetry is not my first choice of literary genre. But I am delighted I did study the work of Seamus Heaney. In reading his poetry, I understand why he has been compared to Yeats and is called by some the greatest poet of the 20th century. I hope I have whetted your appetite to read a volume of his poetry. You will be impressed and proud that we share our Irish heritage with the genius of Seamus Heaney.
At the conclusion of his article, Tom Deignan said it best: “The first day of school in New York City is September 9. We will continue digging! We will not be afraid!”

Bosnia, Herzegovina, and Rwanda underwent genocide leading to an emergence of a ten-year Security Council resolution that brought to light one of the greatest historic silences, the systematic, cruel and extensive habitude of brutality facing girls and women in with weapon conflicts. Thus, the pressure to adopt the 1325 resolution emerged. It was estimated that over seventy per cent of individuals that were not combative were casualties of recent conflicts of Bosnia, Herzegovina and Rwanda, and these were women, girls and children. To almost five hundred women, they were accounted to have been defiled in Rwanda during the 1994 carnage. Some other sixty thousand were also sexually assaulted in the armed conflict in Bosnia and Herzegovina since the year 1991 to mid-2001. Women and girls bodies have been turned to battle grounds, extorted cruelly human minds and hand of armed militia as well as their accomplices, and for those individuals who take evinced the turmoil of armed conflict to dispense assault on the most susceptible individuals of the society. Therefore, the ratification of UNSC1325 resolution by a hundred and ninety-two members’ states of the United Nations (UN) radically adjusted the representation of female humans in situation of conflicts, that is, from that of a casualty to an effective contributor of peace-creating and a negotiator. Therefore, the Security Council resolution of the UN changed from its more normal preoccupation with the abeyance of antagonism, to managing the revoking, more dangerous and durable influence of armed conflict against girls and women.
In acknowledgment of the gendered aspects of conflicts, the International community has developed a comprehensive global normative system on women, peace and security (WPS) to consign the influences on girls and women, as well as to bolster women’s cooperation at all stages of peace processes. Back in the year 2000, the United Nations Security Council (UNSC) made a historic achievement by passing the 1325 resolution on WPS that acquiesce the prejudicial and other time the unique influence of armed conflicts on women. The UNSCR 1325 is deemed as a monument Resolution since it is a political system that that demonstrates how ratification of a gender perspective is critical for the achievement of tenable peace. The verdict reinvigorates the essential duty of female humans in the curbing and verdict of strife, serene agreements, creation and maintaining of peace and philanthropist reverberation to post-discord reconstruction. In this report, the focus is on the policy or guidelines influences such as the gender quotas in post-disagreement parliaments and the increased deployment of female humans’ peacekeepers.
The Security Council (SC) is a principal body of the UN and a political organ of limited appropriateness. With certain anomalies, its functions and powers relate to the sustenance of global serenity and freedom, for which the members of the UN have deliberated upon its basic accountability. Within this area the members of the UN have deliberated upon it very broad competences, as well as authorities not enjoyed by any other global organ to adopt decisions that are legally binding for all members of the UN. When it established the Rwanda and Yugoslav Tribunals the council kept to the laws of armed conflicts so as not to conflict with the rule of ‘nullum crimen sine’. Dharmapuri identifies that the Security Council is a political organ provided with responsibilities and functions within the Charter, to be precise, the authority to develop recommendations and to adopt irrevocable measures for the preservation of global peace and security. Therefore, the functions and powers of the UNSC are to;
Cultivating global reconciliation and freedom in conformity with the standards as well as intentions of the UN. By performing under Chapter IV of the UN Treaty, the council shall, when deemed necessary, petitions the involved confederates in a conflict to resolve it in an amicable manner through mediation, arbitration, judicial settlement or negotiation according to Article 33.
Investigate a situation or a dispute that might lead to global friction. Among the members’ states, these members have the power to investigate nations that are likely to result to conflicts within the borders or between conflicting bordering nations.
The Security Council can advocate approaches of changing such conflicts or the conditions of compact. Inside the chamber, the associate countries suggests as well as assist in the peace settlement of disputes and seize imposition criteria counter to obstinate stares or other members that are likely to fail to agree with the suggested measures.
The SC formulates plans for the establishment of a framework to regulate armaments. These include impulsion models that are extra potent that keeping peace, and are envisaged in Chapter VII of the Article that give power to the Chamber to decide time of peril, a violation of the harmony has taken place as well as enables it among other issues to impose military and economic sanctions.
To govern the presence of a impedance to the peace or feat of attack and to suggest best action meant to be undertaken.
It petitions its parties to affix pecuniary embargos as well as alternative scopes not affecting other aggressive measures to prevent use of force.
The council also takes military actions against an aggressor so as to restore or maintain security of peace. However, the collective use of military or force does not operate in the manner initially intended. It was envisaged that nations would conclude agreements with the UN, enabling the Council to need troop contribution to develop and undertake military intervention operations.
The Security Council recommends the admission of contemporary parties. The Council member states have the power to recommend new member countries of the UN, and it Court of Justice together with the General Assembly.
The Council also exercises the guardianship activities of the UN in critical areas.
Spectacular ceremony in most cases escorts the inscribing in of an accord or agreement. But for global accords such as the UN agreement, every subscriber nation has to comply with the rules of the script and authorize it via the nation’s specific inherent proceedings. There are three basic steps that are involved in ratification. The initial one is a state’s parliament is supposed to approve the charter, in cases it was anticipated by the nation’s constitution. For instance in the UK, both the House of Lords and common will have to approve. Secondly, the head of state is supposed to sign the charter, where it can take a week or a month after being approved by a body of parliament. Finally, the state needs to store a convention of the approval to officially enlist the procedure. The United Nations Security Council being the sixth major organs of the UN that is accused of the keeping up harmony and security was developed back on in the year 1945 after the Second World War, and was meant to address the fall of the League of Nations in maintain peace across the globe. It first session was held on 17th January 1946, but there followed decades of Cold War between the Soviet Union and the United States of America that paralyzed its effectiveness. The UN Security Council was developed by fifteen nations, of which five of these members were pioneers and were permanent members. Pratt and Richter-Devroe outline that these permanent members include the United States of America, France, Russia, China, and the United Kingdom. These nations were considered the greatest powers or rather the victors of the Second World War. In a conference that was held on 25th of April 1945 in San Francisco, and was attended by fifty governments as well as a non-governmental body that took part in drafting the UN Charter. At the same Conference, An Australian delegate by the name H. V. Evatt steered for extensive restriction to veto power of Security Council permanent members but was defeated on voting. The UN was ratified on 24th of October 1945 by five constant parties of the UN Security Council and forty-six other signatories. On 28th April 2006, the Security Council Resolution 1674 reaffirmed the provision of 138 and 139 paragraphs provided back in the year 2005 regarding the World Summit Outcome Document, that the obligation was to shield individuals from atrocities, wrongdoings against mankind, and slaughter. The Security Council re-proclaimed these accountabilities to protect in a resolution of 1706 of 31st August 2006 against, genocide, crime against humanity, genocide, and war crimes.
Since October 2000 the world has changed because of the appropriation of the Security Council Resolution 1325. It was the incorporation of sexual orientation touchy arrangements in the Security Council segment of Bosnia and Herzegovina (B and H), and was made with the nearby collaboration of the non-legislative association by the name Zenen Zenama, the Agency for Gender Equality of Bosnia and Herzegovina, the Ministry of Human Rights and Refugees, just as the UN Women. The UNSCR 1325 was executed by Zene Zenana just as the Agency for Gender Equality of B and H, not overlooking the Coordinating Board for the usage of the Action Plan for 1325 in Bosnia and Herzegovina and ten nearby ladies associations. The subsequent arrangement of the task was to cultivate limits of the Coordination Board and the security layer to complete and encourage the Action Plan on the UNSCR 1325. It was achieved by methods for raising the cognizance about the different security prerequisites of people and how to standardize sexual orientation into arrangements and projects. The plan likewise foreordained to make good to the effort of UNSCR 1325 at the nearby stages, by means of coordination with neighborhood NGOs just as organizations, just as to increase open mindfulness concerning the UNSCR 1325 and the Action Plan.
For any form of Resolutions meant to address WPS, each of them recognizes the former and every stresses that the verdicts are supposed to function concurrently in addressing a number of issues. The UNSCR 1325 and 1889 underlines women’s leadership in creation of peace and prevention of conflicts. The UNSCR 1820 and 1888 aims at curbing and responding to conflict-related sexual violence. The UNSCR 1889 was first introduced by Vietnam and was consistently affirmed on fifth of October 2009 and was to make requests to UNSCR 1325, which was the pioneer goals that concentrated on harmony, ladies and security. The UNSCR 1889 emphasizes the interest of ladies in all phases of the harmony procedure, Most huge, it requests administering just as organization answerability systems UNSCR 1325 doesn't have. The goals effectively support collaboration with common society, explicitly ladies' associations.
Therefore, according to Coomaraswamy (2015) the UNSCR1889 involves;
Participation of Women in Decision-production and Peace Processes
UNSCR 1889 calls for women as agents of change, whereby, there was call by the Secretary- General as well as member states to increase the participation of women at all levels of the peace process. The resolution ingeminates the essential role of women in curbing conflict and building peace, more particularly, it identifies that in times of conflicts and post-conflict, women in most cases regarded as victims, instead of being leaders and stakeholders capable of aiding in addressing and resolving . The UNSCR 1889 emphasizes that there is need to rivet on enabling and protecting women. All members of the UNSCR are implored to make sure that gender normalizing in all factors of post-conflict recuperation. The Security Council likewise was mentioned by the contributors and counsellors to expand the number of ladies in peacekeeping tasks by the Secretary-General by creating strategies . It additionally pushes benefactors to concentrate on the jobs of ladies and request straightforwardness in following the assets assigned for assessing the requirements of ladies in post-war conditions. Further, the chamber addresses the Secretary-General to continue to post-sexual orientation counsellors in UN assignments.
Compliance with UNSCR 1889
As indicated by Pratt and Richter-Devroe, the UNSCR 1889 calls upon all parties to make a national arrangement in consistence with UNSCR 1325 . It is intended to perceive the estimation of the United Nations Steering Committee that created from an Institute for Inclusive Security and Realizing Rights occasion in April 2009. The Input of the Steering Committee is invited by the Security Council to advance permeability just as encourage coordination inside the UN system in assembling the tenth commemoration of UNSCR1325.
The needs for security, priorities and interests of men and women in any provided ambience are varying. These dissimilarities are specifically acute in post-conflicts circumstances because of heightened levels of global insecurities. Gender-based violence to be precise is the main issue. Nonetheless, genders there have been marginalization of gender in Security Sector Reforms (SSR). There have been adjustments of policy since the adoption of resolution 1325 of UN, but the breach between policy and practice remain essential . Forthwith post-conflict, donors as well as governments tend to concentrate on train-and-equip programs for security detachments. Gender matters as well as justice reform are disparaged as being less prioritized, more political and hard to perform. Either gender is regarded, there is a tendency steered towards template suggestions based on heightening the representation of women in security forces to at least 30%. According to the NATO Secretary- General Anders F. Rasmussen in a conference depicted that women are not just victims of conflicts. Women must be part of the conflict solutions, and if they are not active participants in development of peace and reconciliation, the needs, views as well as the interests if half of the populations within conflicted locations are not effectively represented. Arguably it is defaming, and also undermines all efforts to achieve a peaceful co-existence. The UNSCR 1325 was a landmark resolution since it not only acknowledges the influence of conflict on women, but also acknowledges the significant role that women can play, and must take part in so as to curb and resolve conflict and develop peace in affected areas. Through UNSCR 1325 was to emphasize countries such as Rwanda to put forth program such as Forum of Rwandan Women Parliamentarians (FFRP) which was set up back in 1996 that would promote gender-sensitivity professional working surrounding as well as institutional culture that is free from discrimination and harassment. It was further meant to reduce barriers by developing conditions that are conducive to attract more women, sponsoring recruitment, reservation as well as advancement of women and involving well-capable, specifically in senior positions that can facilitate peace- creation and keeping, reconciliation, reintegration and wilding rule of law within the UN Security Council.
Specialists have recognized that the high number of ladies in any parliament fundamentally adds to more grounded regard for issues encompassing ladies. Political support of ladies is a crucial catalyst for sexual orientation equivalent portrayal and a flat out vote. It cultivates ladies to straightforwardly take part in open dynamic and it is a method for ensuring that there is better responsibility to ladies. The start of political responsibility among ladies has uplifted even the quantity of ladies in dynamic positions, however, it doesn't end there. According to Mazur, there is need to sharpen sexual orientation in states administrations . These are changes that will guarantee that ladies are chosen in legitimate positions in this manner cultivating sex equity in open strategy and ensure that there is execution. A column in the United Nations seek to propel ladies' political partaking just as compelling administration, to settle on sure that the dynamic technique is participatory, responsive, evenhanded and comprehensive . Hence, tries are engaged through cardinal passageways that are fit for encouraging the poise among ladies by preparing sweeping circle and long haul impact. As indicated by Debusscher and Ansoms, ten years after the 1993 Rwanda slaughter, the nation was perceived for choosing the world's most elevated number of ladies in the parliament . This was because of government establishments that were reproduced, the strategy structures reframed and laws that upheld sex equity and incorporation of ladies. Correspondingly, in Bosnia and Herzegovina, according to Miftari, there has been the selection of approaches and game plans to incorporate sexual orientation uniformity standards keeping up of sex-disaggregated insights and usage of certifiable measures. These measures and systems were embraced in 2003 and it was characterized as Convention on the Elimination of All Forms of Discrimination of Women and the targets were characterized in the Beijing Declaration and Platform for Action. Rošul-Gajić highlights that these shows have become a necessary part on Bosnia and Herzegovina, and thus, ladies are spoken to both in the official and authoritative frameworks all secured by laws. There were directed without hesitation during the second intermittent Gender Action Plan of Bosnia and Herzegovina for the period somewhere in the range of 2013 and 2017. They were significantly supported by the United Nations and the European Union. The equivalent portrayal was in territories of concern, for example, those intended to fortify frameworks in an administration.
A dynamic civil society is a key component in a vote based society. Non-legislative associations (NGOs) are significant on-screen characters. They articulate the necessities and interests of residents work to consider governments responsible, campaign for change, complete research, create and prepare bodies’ electorate and even offer direct types of assistance. According to Mazur the circumstance of women's associations and sexual orientation correspondence advocates fluctuates all through the locale . The heritage of 'constrained liberation' of the socialist time and the current monetary emergency has implied that it is frequently hard for associations to build up a profile and authenticity. However, late years have seen noteworthy development in the ladies' development and associations working for sex balance. In Bosnia-Herzegovina, since mid-19th century women non-governmental Organizations were quite prominent during the genocide and the post-war. They were successfully operating and became more successful after they were established by the UN that saw the need to promote civil society. The intention was to focus on fostering social care services in terms of food distribution, medical assistance and shelter. In the following decades, the NGOs expanded their scope to foster capacity development in tr5aining and education. In Rwanda, Debusscher and Ansoms identifies that there exist a network of fifty-eight Rwandan associations that foster women, peace and development . This network is depicted as Pro Femmes/Twese Hamwe (PFTH), and has managed to harness the firm political that fosters human rights and specifically women rights. The Rwandan Civil Society Platform (RCSP) in another no-governmental organization that was created in the year 2004 was created with a purpose to analyze significant challenges faced by the Rwandan people and support common strategies and positions to fix these challenges. It also creates and nurtures an information framework to facilitate the civil society to attain its mission, acting closely with all stakeholders. These stakeholders include the Forum of Rwandan Women Parliamentarians (FFRP) which was set up back in 1996 on the dynamism of women Deputies in the Transitional National Assembly.
At one time in Rwanda, the Rwandan President H.E. Paul Kagame said that gender equality in each sector of governance cannot be a favor, but it is a right, and it is the way it should be. The right to equality is not something to be given or taken. Therefore, women alongside men should be given a political boost and working with more stakeholders to possess a comprehensive, and a transparent co-existence. In Bosnian and Herzegovina, there are still responsibilities to advance with key ways to deal with accomplish a target set by the Beijing Declaration and Platform for Action. In any case, there are more procedures that Bosnia and Herzegovina need to do in advancing more ladies in different parts in the advancement of equivalent portrayal. These incorporate; prioritization of more ladies in the work advertise and limit the work showcase isolation. There is a requirement for Bosnia and Herzegovina to create open approaches that forestall and battle brutality against ladies and aggressive behavior at home. At last, In Bosnia, Herzegovina and Rwanda, there requirement for critical strides in battling exemption against sexual stalkers. While there have been extraordinary endeavors made up until this point, there is a requirement for these nations to make programs that help ladies who have endure sexual viciousness during local questions.
The Convention of UNSCR 1325 and 1889 had a commitment that stems for the command of institutional systems for sexual orientation balance and from commitments under the law to take care of and encourage the execution of worldwide and national sex equity in Rwanda, Bosnia and Herzegovina. The report has additionally referenced that the United Nations Security Council was made by five-part conditions of the USA, UK, Russia, China, and France after the Second World War. It was created to meet a significant motivation behind keeping up global harmony and security as per the standards just as reasons for the United Nations. Through the presentation of projects, for example, Forum of Rwandan Women Parliamentarians (FFRP) which was set up in 1996 and Convention on the Elimination of All Forms of Discrimination of Women of 2003 in Bosnia and Herzegovina. Significant steps have been achieved in those nations after the destructions in Rwanda and decimation in Bosnia and Herzegovina in governmental issues, common society and legislative issues. In any case, more estimates should be taken by the nations to encourage more ladies associated with all segments of administration, be secured in situations where aggressive behavior at home, sexual abuse that is as yet constant until today.

Suppose you are trying to collect data for a phone application that monitors heart rate. You are able to come up with some handwritten rules or formulae through an empirical study. But the observation requires an impossible duration and then you begin to notice the problem is too complex, as the heart rate data keeps changing. The handwritten code is suboptimal. How can you cater to such a complex problem? This dilemma can be solved by Artificial Intelligence programming or AI.
But here comes another problem! With a plethora of AI programming languages that are used to give instructions to machines, how do you pick the best programming language for AI? There are a bunch of options to consider before we answer this query.
In this article, we will explore six popular AI programming languages that can help you kickstart your AI journey, but first, let’s understand the concept behind AI programming.
AI comprises 4 categories; machine learning (supervised and unsupervised), deep learning, natural language processing, and robotics. Let’s see how these subsets can be achieved with the artificial intelligence programming languages we discuss in the upcoming sections of the article.
What Is AI Programming?
The incorporation of the human brain blueprint into writing and designing computer programs to accomplish tasks is known as AI programming. But why was there a need to integrate artificial intelligence in an already successful field?
A comparative analysis between regular programming and AI programming highlights some deficiencies in traditional programming. The fact that programs crash or come to a halt due to bugs, invalid instructions, or incorrect address values, is one factor that shows traditional programming requires the incorporation of AI.
AI programming does not require all possible scenarios in a problem to be defined. It is proficient in learning from historical data, identifying patterns, devising solutions to problems, and then using the correct formula to solve similar problems in the future; this way, there are fewer crash reports. The algorithm can learn from non-linear or linear data to form complex relationships, update as more information becomes available, and give scalable solutions derived from large data sets.
Simply put, conventional programming was the saturation of human capabilities and excellence, and AI programming is the tool that was needed to break the glass ceiling.
Here are three features of AI programming that can empower programmers to reach new heights.
1. Learning Processes
An algorithm, which is a problem-solving formula, is used to acquire data and convert it into actionable information. This particular form of information enables decision making and problem-solving. That’s right! AI programming allows computers to solve their own problems by using accurate, credible, and relevant information.
2. Reasoning Process
When you are programming, you find yourself analysing your every decision. Similarly, AI programing coined in the framework of the human mind does the same. According to the outcome it must reach, it selects the appropriate algorithm. It is as simple as using the correct formula in Mathematics to reach the desired answer.
3. Self-Correcting Process
Just like humans correct their mistakes, smart machines are well-versed in self-evaluation and correction. Self-programming AI can figure out that it has made a mistake when an unsought outcome is obtained. It will learn from the mistake instead of coming to an abrupt halt. This allows artificial intelligence programming to consistently improve.
6 Languages You Can Use for AI Programming
Now that we have discussed some basic concepts, let’s talk about the language options you have for programming AI if you are a novice at this niche.
Choosing a language is a critical decision to make. Why? Because AI has an abundance of benefits but it is not an easy technology to use and develop. Secondly, the success of your entire project is dependent on the choice you make. Too much pressure? Read on to put an end to your ambiguity about the different AI programming languages.
Python, an interpreted object-oriented language, is one of the most sought after languages when it comes to programming AI.
The vast resources, in the form of libraries, give programmers the advantage of pre-written codes, configuration data, templates, help data and superior visualisation tools. Some specific libraries for Python can be used for specific subsets of AI.
PyBrain is a library for machine learning that not only offers powerful algorithms but also a predefined environment to test them in, in terms of compatibility and scalability. You can also compare algorithms against each other to select the best one.
Nerolab is another library where coders can find neural networks and frameworks to achieve deep learning and train algorithms.
For natural language processing, python AI programming provides a framework called Gensim, to extract semantic topics from documents and process raw text. Similarly, libraries and frameworks can be found for robotics as well, an area that is in its early stages.
Python is an easy language to pick up, even for beginners, due to its resemblance to English. Thus, one can learn AI programming rather than only focusing on conceptualising the language. Its syntax is also simplistic, enabling a programmer to work with complex systems. The modular architecture creates further simplifications by dividing the functionality of the program into modules that contain resources to execute singular aspects of a function, one at a time.
Python offers great flexibility with not just programming styles but also with its easy integration with various other AI programming languages such as C++. This versatile language is operational on various platforms too so you can start your python AI programming journey on Windows, Linux, Unix or Macintosh amongst various other platforms.
Python plays a key role in the growing global community of data scientists and programmers who contribute to the consistent development of the artificial intelligence programming language. This also opens up avenues for help and guidance for novices. For AI programming, Python is also great for teamwork. Due to its readability, colleagues can easily understand each other’s work.
When it comes to analyzing and manipulating data for statistical analysis, R is a clear winner. It is an interpreted language that has procedural meaning. The code organisation allows code reuse through modularity, giving functions to applications by working together.
As machine learning involves large amounts of data, R is competent in crunching data and reorganising it. It can also break up large datasets into simple test sets as an added ease to the programmer. It is a known statistical language that specialises in data analysis and visualisation. This specialisation has made it a go-to language for most statistical purposes in AI programming.
R is also robust in mathematical capabilities, to the extent that programmers have commended it to be on par with MATLAB. It can utilise vectors, linear algebra, and matrices to process data rapidly, which is a much-needed attribute for machine learning.
R is one of the leading AI programming language an open-source language, which means novices can benefit from pre-written codes that have been contributed by the R developer community. R offers various packages that can be utilised for the supervised machine learning subset. Let’s see what packages this language has to offer.
One package is CARET, which stands for classification and regression training. When a programmer is building AI models, this package facilitates training and prediction. This is how software built with AI programming can formulate smart predictions for users at the front end.
With Kernlab, one is equipped to execute projects based on kernel-based learning algorithms. These projects identify the patterns and relations in the data. This is how software built with a kernel method can pin the relation between client and server and identify patterns such as listening habits in music applications.
Furthermore, R can create a testing interface for a programmer to test data analysis that creates synergy between humans and machines. R has complex ways of achieving outputs and can be a little difficult to get a grasp of at first. However, once you are proficient enough, you will find it is easy to use it for programming AI applications.
C++ is a general-purpose compiled language that offers tons of advantages. This statically typed language declares and determines its variables at compile-time, and shows errors and inconsistencies. This feature can help in algorithm model development because it makes it easier to work with relational databases.
Compiled languages enjoy some high-quality optimisation features. The fact that this language is directly converted into machine code that is easily executed can save you precious time.
However, one thing C++ is really known for is game AI programming. Enemies, or the opponents in the game, are the most paramount elements, followed by game graphics, interactive elements, and overall gaming experience. C++ can be used to code game opponents that get stronger with every level.
In order to do this, data is collected from the user to understand their strategies and then this is coded into the game software to teach the opponent how to combat better. The algorithms that C++ derives are robust in handling varying scenarios.
C++ is also compatible with other languages, such as Python or R, and is often used as a background language with these two. It has its fair share of libraries and resources such as C++ Boost for mathematical operations. However, AI programming for beginners would require more packages that other artificial intelligence programming languages offer already.
MATLAB is a proprietary programming language, meaning it is domain-specific, rendering it to extract optimal solutions to a specific class of problems. Problem-solving is one of the key attributes of AI programming. With its arsenal of mathematical resources, MATLAB is fully equipped to qualify as one of the best programming languages for AI.
MATLAB is an AI programming language that can be used to teach students mathematical fundamentals such as calculus and statistics. These numerical coding languages come with resourceful packages that are known to surpass the quality of other AI programming language’s resources.
This AI programming language has a toolbox that enables symbolic computing which uses algebraic computation to develop algorithms for the manipulation of mathematical expressions. It is an interpreted language so variables do not have to be defined unless the programmer wants to treat them as symbolic objects.
The square identity matrix of n size can be generated for matrices of any size with numerous zeros. It has simple functions to generate mathematical formulas. MATLAB uses array programming, which means solutions are obtained by giving the application of operations an entire set of values at once, using this linear data structure. This makes it possible to solve complex computing problems involving vectors and matrices as dimensioning is not required. This allows the programmer to develop neural networks that are capable of deep learning. Programmers train the neural network via representational learning through image or speech data inputs.
MATLAB is able to handle a heavy load of input due to its sophisticated mathematical capabilities. It has libraries that offer a large computational algorithms collection, ranging from basic functions like sum, sine, cosine, and complex mathematics, to more superior functions like matrix inverse and matrix eigenvalues. MATLAB libraries can be integrated with other languages as well, which can be a benefit for novices.
Prolog is a logic computing language that is well-known for incorporating artificial intelligence technology. Logic computing is one of the paradigms of AI programming that expresses facts and rules about problem domains. This gives it complex problem-solving capabilities similar to MATLAB, to some extent.
Another paradigm of Prolog is declarative programming that builds the structures of the program by expressing the logic of computing without the description of control flow (the order in which individual statements or functions are called or executed).
These two paradigms empower Prolog to perform string searching algorithms to locate where strings (patterns) can be found within a larger dataset. Secondly, tree-based data structures, which are non-linear structures that identify a hierarchy, can also be identified.
The hierarchy system leads to the development of neural networks. Several neural nets are piled on top of each other to create a hierarchy for more accurate classifications and predictions.
With these capabilities, Prolog can be used to develop natural language processing as it can make sense of human languages by understanding the connection between words in a sentence in multiple human languages.
Prolog also excels in its capabilities of spatial knowledge due to its quality of understanding relationships between objects. So, for instance, it can make sense of Object A being behind Object B that is parallel to Object C. Such technology is also used when developing intelligent commuting applications that can give real-time updates of traffic.
Java is a cross-platform language that you can utilise to learn AI programming. This paradigm gives you the freedom to work on multiple platforms by transferring your work. However, you might be required to compile your code according to each platform.
Another feature that can help budding AI programmers is the garbage collector. This is a memory management system that enables Java to manage objects for you. With a decluttered system, the programmer can work on other key aspects such as the visualisation of the project by making use of Java’s widgets.
This language is able to handle large scale projects that can employ neural networks and machine learning. It has specific libraries for neural languages, such as Neuroph, which is an open-source framework to create and use neural networks.
The goldmine for this language is the Java Virtual Machine (JVM) that can optimize computational performance and thus rank it above many languages. It has a low demand for resources because of its inbuilt memory management system. This way, it can handle large amounts of data and compute it faster than many languages.
Java is considered an easy language and many enterprises use it due to its optimisation abilities which make it easy to handle artificial intelligence projects.
Factors That Can Affect Your Language Selection
Now that we are at the end of the article, as promised, let’s discuss what the best AI programming language is.
At this point, we would like to point out that the whole concept of “best AI programming language” is quite unrealistic. Language selection is a very subjective decision. There are three factors that need to be taken into consideration before a language can be selected.
By asking yourself the following questions, you can discover what the best AI language is for you.
1. What is my background?
Analyse your background and categorise it into one of the following realms: mathematics, science, engineering.
If you have a strong math background, then chances are, you might have been taught vectorial concepts via languages such as MATLAB. If science is a disciple you identify your background with, then perhaps languages such as R would be more appropriate for you. A person with an engineering background might resonate better with Java.
There is a strong overlap of concepts in programming languages so you can use languages from other disciplines if you understand its prerequisite concepts. Otherwise, you can also focus on utilising the language you are already well-versed in instead of learning a new language.
2. What is my proficiency level?
This is the level of expertise you are on. As a beginner of AI, it is strongly advised that you start with an easy-to-grasp language such as Python that comes with a large library resource.
If you are an intermediate-level developer, then you can handle more complex languages such as R or Prolog, and then comes C++. Once you reach a superior level of expertise, the opportunities are endless, as all language entry barriers will be lifted.
You may even make use of multiple languages for a single project.
3. What is the nature of my project?
This question seeks to understand the type of project you are executing. What type of software are you designing? Are you making an insight application such as a diagnostic system for healthcare? Perhaps Python can help in the creation of superior algorithms.
Are you developing games? C++ is the most well-known language for the game development industry. Its graphic development and machine learning abilities will help you in producing classic end results.
Do you require spatial knowledge? Perhaps you are working on an application that can be used for architecture in designing floor plans. You can then invest in learning Prolog.
The nature of projects is endless and once you know what it is you want to achieve, you can simply match your demands to the features of any language. This will help in finding you a compatible match.
Once you ask yourself these questions, you will be well-equipped to identify what the best AI programming language is for you. And once you make up your mind, there are plenty of AI programming tutorials along with other resources you can find online to begin your learning process.
So what programming language is used for AI? It should be the one that fulfils your requirements!
AI programming opens up a whole world of new possibilities for programmers, app owners and end-users alike. Using artificial intelligence technology for programming has led to various successful products and services in all walks of life.
The languages available to dive into the world of AI programming are many and varied. This field is open to novices who can take advantage of easy languages such as Python to learn AI programming in no time. Though artificial intelligence technology is not easy to employ, it is, undoubtedly, the gateway to acceleration and success. | <urn:uuid:f8d6b2d8-f518-416b-b194-c8ec913b8331> | CC-MAIN-2024-51 | https://www.goodcore.co.uk/blog/ai-programming/ | 2024-12-05T18:34:22Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066362401.69/warc/CC-MAIN-20241205180803-20241205210803-00100.warc.gz | en | 0.94049 | 3,519 | 3.15625 | 3 |
While there is no set number for all snakes, each species has its typical range. For example, a ball python may only lay a few eggs, while an Indian rock python might deposit a larger batch, even up to 100 at a time. Depending on the species, certain influences such as food availability and thermal environment can alter the frequency of their egg-laying. Interestingly, some snakes lay their eggs yearly, and others take longer breaks between batches. This leads us to explore the fascinating world of snake reproduction that is teeming with diversity.
The number of eggs a snake lays can vary, with some species laying as few as 3-4 eggs while others may lay up to 100 eggs in a single clutch. For example, large snakes such as reticulated pythons can lay up to 100 eggs, whereas smaller snakes may lay between 10-30 eggs.
Egg-Laying in Different Snake Species
When it comes to the number of eggs a snake lays, there’s a wide range. For instance, the ball python typically lays 4-10 eggs per clutch. On the other hand, the Indian rock python holds the record for laying one of the largest clutch sizes among snakes, with a range of 35 to 100 eggs in a single clutch.
It’s fascinating to note that this variation occurs between different species and within the same species. King cobras can lay anywhere from 20 to 40 eggs in a single clutch—the Indian rock python, mentioned earlier, holds an astounding record.
An interesting aspect is that larger snakes often lay more eggs than their smaller counterparts. For instance, the green anaconda holds the record for having the largest clutch size among all snakes. Their clutches generally range from 35 to 100 eggs, reflecting the species’ large size and remarkable reproductive capacity.
Larger live-bearing snakes like boa constrictors can have up to 50+ babies in one clutch. In contrast, small snakes may lay anywhere between 10 to 30 eggs.
Rattlesnakes usually lay between 4 and 25 eggs per clutch—a diverse range even within closely related species, demonstrating differences in their reproductive habits.
By exploring these specific examples of snake species and their egg-laying habits, we gain a deeper understanding and appreciation for the incredibly diverse nature of snake reproduction. Each species has its unique strategy for ensuring its survival through reproduction, making snake reproduction an endlessly fascinating subject.
In this comprehensive exploration of snake reproduction, we’ve witnessed the incredible diversity of egg-laying habits across various snake species. Now, let’s delve into the frequency of snake egg-laying and understand the factors influencing this behavior.
Frequency of Snake Egg-Laying
The frequency of snake egg-laying depends on several important factors. While some species lay eggs annually, others may not do so every year. Additionally, environmental conditions and the reproductive strategy of each species play a crucial role in determining the egg-laying frequency.
Snakes are highly attuned to their environment, greatly influencing their reproductive behavior. For instance, food availability is critical. When food sources are abundant, snakes may be more likely to lay eggs more frequently, as they have the energy and resources to support reproduction. Conversely, if prey is scarce, snakes might delay or reduce egg-laying frequency to conserve energy for survival.
Furthermore, the thermal environment plays a significant role in snake reproductive frequency. Cold temperatures can slow down metabolism and reduce overall activity levels, potentially impacting a snake’s reproduction ability. On the other hand, warmer climates might facilitate increased activity and energy expenditure, allowing for more frequent reproductive cycles.
For instance, certain species of snakes in temperate regions may only lay eggs biennially due to seasonal fluctuations in temperature and food availability. In contrast, snakes inhabiting tropical regions with consistent temperatures and food resources may exhibit more frequent egg-laying behavior.
Additionally, the reproductive strategy of each snake species contributes to its egg-laying frequency. Some species have evolved to invest heavily in fewer offspring, resulting in less frequent egg-laying events. Conversely, other species may opt for more numerous but smaller clutches more frequently throughout the year.
Understanding the factors influencing the frequency of snake egg-laying provides valuable insights into the reproductive biology of these fascinating creatures. Environmental conditions, including food availability, thermal ecology, and distinct reproductive strategies, all contribute to the diverse patterns of egg-laying observed across snake species.
In order to fully comprehend the intricacies of snake egg production, it’s crucial to delve into the various factors that impact this crucial aspect of snake reproduction without getting lost in a maze of details.
Factors Impacting Snake Egg Production
Many factors can influence the number of eggs a snake lays. One key factor is the age and health of the snake. Like any living creature, a healthy adult snake is likely to produce more eggs than one without. Young snakes may have smaller clutches initially, increasing in size as they mature, while older ones may experience a decline in clutch size.
Interestingly, the size of the snake also plays a significant role. Larger snakes generally produce more eggs than smaller ones. This difference in clutch size based on physical dimensions hints at how these creatures might instinctively adjust their reproductive output based on their capacity and resources available.
Environmental conditions such as temperature and humidity directly impact egg development and hatching success. The nesting area’s ambient temperature and moisture levels are crucial for egg viability. Some species thrive in varying climates, impacting their breeding behavior accordingly.
significantly affects a snake’s ability to produce and lay eggs. Suppose a female snake isn’t getting enough food. In that case, she may not have enough energy to produce a large number of eggs, or her body may delay reproduction until better conditions are available. Conversely, when food is abundant and healthier, larger clutches are expected.Furthermore, different snake species’ mating behavior and reproductive strategies significantly influence the number of eggs produced. Some species employ intricate courtship displays and invest considerable energy into mating rituals.
This comprehensive analysis of factors impacting snake egg production highlights the intricate web of biological intricacies of reproduction. From physiological indicators like size and health to external environmental variables such as temperature and food availability, each factor plays a significant role in shaping the reproductive outcome for snakes. By understanding these factors, we gain valuable insights into snake egg production’s complexities.
Understanding the nuances of snake reproduction, from factors influencing egg production to maternal instincts, sheds light on the remarkable world of snake parenting—a perspective that is often overlooked but crucial for appreciating these fascinating reptile creatures.
Snake Reproduction: A Maternal Perspective
While it may be commonly believed that snakes don’t provide parental care for their eggs, some exceptions are worth noting. In the vast world of snakes, the maternal behaviors are as diverse and interesting as the species.
For example, the African rock python is known for its unique parenting style. This snake species is one of the few that puts significant effort into looking after its eggs. The female African rock python incubates her eggs by coiling around them to regulate the temperature. This maternal behavior is especially important, as the proper heat ensures the embryos develop healthily within their shells.
Imagine a mother python patiently protecting her clutch of eggs, ensuring they remain safe from predators and providing constant warmth and security until they hatch. It’s a fascinating example of maternal determination and dedication.
While some may assume that reptiles lack complex behaviors like parental care, these examples challenge such assumptions and provide a deeper understanding of reptiles’ intricate strategies for successfully raising their young.
Some might argue that this phenomenon is not common among all snake species and should not, therefore, be overgeneralized as typical maternal behavior for snakes. However, even observing this behavior in specific species offers invaluable insight into the diverse and complex nature of snake reproduction.
Understanding these unique maternal behaviors illuminates the richness and complexity of snake reproduction, offering a fascinating glimpse into the diverse strategies snakes use to ensure the survival of their offspring.
Role of Age and Environment in Snake Reproduction
Her biological maturity does not solely determine the ability of a female snake to produce eggs; her age also influences it. Younger female snakes may lay fewer eggs than their older, more mature counterparts. This is because as female snakes grow and reach sexual maturity, they are better equipped for successful reproduction.
Research has shown that age can be an important factor in the reproductive success of female snakes. For instance, a young ball python may only produce a small clutch of eggs, while its older counterpart may produce a significantly larger clutch. It’s similar to how young humans may not be ready for certain responsibilities compared to adults.
Furthermore, environmental factors play a crucial role in snake reproduction. Snakes are ectothermic, relying on external heat sources to regulate their body temperature. The ambient temperature determines the rate at which their bodily processes occur, including reproductive readiness.
Environmental Factors Affecting Snake Reproduction
Environmental Factor | Impact on Snake Reproduction |
Temperature | The optimal range varies between 75°F and 95°F (24°C to 35°C). Warmer temperatures can stimulate breeding behavior, while cooler temperatures may delay or inhibit it. |
Humidity | Adequate levels are crucial for egg development and hatching. Excessive or insufficient humidity affects egg viability and embryo health. |
Nesting Sites | Suitable locations are critical for successful reproduction, promoting optimal incubation conditions. |
Understanding these dynamics sheds light on the delicate balance required for successful snake reproduction—a harmony between biological maturation, environmental suitability, and physiological preparedness.
This careful dance of nature’s elements shapes the intricacies of snake reproduction—the stage is now set to delve into the captivating behaviors accompanying this remarkable reproductive process.
Unfurling Mysteries of Snake Breeding Behaviors
Cultures worldwide have woven enchanting tales around courtship rituals, from humans to animals, and snakes are no exception. When it comes to snake mating, the elaborate dance of pheromones and intriguing behaviors leave us marveling at the wonders of nature.
Different snake species exhibit a varied array of courtship behaviors and communication methods. Take the female’s pheromone release, for instance—an alluring yet potent scent that signifies breeding receptiveness, emanating from skin glands strategically placed to attract males. It’s a captivating display of nature’s choreography.
Pheromone communication is essential in initiating courtship, as each species has its unique blend of scents that serve as an invitation for potential mates. Males pick up on these signals and embark on a quest to locate the source, often engaging in an intricate dance of head bumping and circling the female. This pheromone-driven communication holds a certain allure, drawing us into the mesmerizing realms of animal behavior.
Once a male detects a receptive female through pheromones or other cues, he embarks on courtship rituals that can be both visually striking and intriguing. It may involve graceful movements or displays that showcase his strength and vitality to win over the female. This awe-inspiring display embodies a captivating dimension of snake reproductive behaviors.
It’s fascinating to note that this process can vary greatly between different species. For instance, male garter snakes engage in elaborate group courtship dances known as “mating balls,” where several males pursue one female simultaneously. This spectacle highlights the intricacies and diversity of snake breeding behaviors across species.
The Intriguing Hemipenile Insertion
Another mysterious aspect of snake mating involves the male’s method of insemination. Unlike mammals, snakes don’t possess external genitalia. Instead, males have paired reproductive organs called hemipenes located inside their tails. When ready to breed, they maneuver their hemipenes into position to copulate with the female.
As we unravel these enchanting tales of courtship and communication within the serpent world, it becomes evident that snake reproduction is a tapestry woven with intricate behaviors that inspire wonder and awe.
Snake mating behaviors unveil a world full of enigmatic rituals and evolutionary marvels, adding an extraordinary dimension to our understanding of animal behavior. | <urn:uuid:c955a731-69bb-448f-80b9-a81508398fe3> | CC-MAIN-2024-51 | https://www.interestinganimals.net/how-many-eggs-does-a-snake-lay/ | 2024-12-05T19:25:41Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066362401.69/warc/CC-MAIN-20241205180803-20241205210803-00100.warc.gz | en | 0.921317 | 2,510 | 3.8125 | 4 |
Biodiversity is the totality of all inherited variation in the life forms of Earth, of which we are one species. We study and save it to our great benefit. We ignore and degrade it to our great peril.
Imagine you’re about to set off on a bike ride. Your bike has the usual parts – wheels, handlebars, pedals, frame, and all the little screws and bolts holding it together (Figure 1). If you were asked to give up one piece of the bike, which one would you choose? Maybe the basket at the front? It would still be rideable. What if you had to remove 10 parts? In deciding which pieces to remove and whether it’s safe to ride it afterward, you’ll weigh the importance of each part to the bike’s overall function.
Scientists are grappling with similar questions about ecosystems. In 1981, American scientist duo Paul and Anne Ehrlich equated extinctions with losing rivets from an airplane wing and having to evaluate whether it could still fly, much like the bike example above. (Ehrlich and Ehrlich, 1981). The Ehrlichs’ “rivet-popper” hypothesis suggests that it’s not wise to lose species because each one may play an ecosystem role. Through the many species they contain, ecosystems provide essential services to human societies, such as food provision, nutrient cycling, and water purification (See our Environmental Services and Economics module). Are certain species more crucial than others?
“But the Anthropocene isn’t a novel phenomenon of the last few centuries. Already tens of thousands of years ago, when our Stone Age ancestors spread from East Africa to the four corners of the earth, they changed the flora and fauna of every continent and island on which they settled - all before they planted the first wheat field, shaped the first metal tool, wrote the first text or struck the first coin.”
- Historian Yuval Noah Harari, Hebrew University of Jerusalem
People have been modifying the habitats they inhabit for thousands of years. Archaeological and paleoecological evidence shows that by 12,000 years ago, humans lived on almost three quarters of land on Earth, and by 10,000 years ago they were using land-altering practices such as burning, hunting, farming, and domestication of animals (Ellis at al. 2021). Today, we associate human use of natural areas with degradation and extinction of species. But that was not always the case.
Hunter-gatherers and early farmers, through lower intensity subsistence practices, in some cases had neutral or positive impacts on biodiversity. Forest gardens, multiple crops, nomadic populations, and field rotations from fallow to cultivated made for diverse landscapes with high biodiversity. A study (Armstrong 2021) of forest gardens in British Columbia, which were cleared and cultivated by Indigenous communities until two centuries ago, revealed that they still have more diverse plants and animals than the conifer forests around them. Cultural stewardship practices of native inhabitants, including planting edible species like hazelnuts, cranberry, and wild ginger, made for more ecologically complex and diverse habitats (See our Biodiversity I: Patterns module).
Today, higher human densities on Earth and more intensive practices such as industrial agriculture and global supply chains, have tipped the scales towards negative impacts of humans on biodiversity.
In the photos above (Figure 2), what evidence can you find of how humans have changed their environments? Your list may get pretty long. What other changes do humans make to natural landscapes as we live, work, and play in them?
All animals modify their habitats to some degree as they nest, find food, or otherwise use resources. Humans are exceptional at altering habitats to meet our needs for shelter and food, plus distinctly human needs like entertainment. As a result, nearly every habitat in the world has been altered by people. A recent global assessment estimated that 75% of terrestrial and 66% of marine environments have been significantly altered by humans (IPBES 2019). Why do these changes matter?
In subsistence economies, such as those of Indigenous Peoples, humans and biodiversity were largely compatible. In global market economies supplying dense human populations, they’re not (Otero et al. 2020). For example, more than 85% of global wetlands have now been converted to other, lower-biodiversity uses. Just as a bicycle with missing parts may not function as well, ecosystems with lower biodiversity mean worse function. As habitat is lost, you’ll find fewer large animals, disrupted interactions between species, lower breeding success, and myriad other changes. As human populations continue to grow and consume resources, other species are increasingly deprived of resources and nudged towards extinction.

What features break up the forest in this landscape? (Figure 3)
Conversion of natural habitats to human uses breaks up ecosystems into patches of habitat, often separated by man-made barriers. Small land conversions of land may promote biodiversity by creating more diverse habitat conditions. For example, in northernmost Patagonia, the monkey-puzzle tree (Araucaria araucana) was planted and maintained through localized burns to clear areas around it by Native Peoples. With the elimination of these controlled fires and the advent of large farming from Euro-American settlement, monkey puzzle trees are now endangered (Nanavati at al. 2022).
Large-scale land conversions, leaving small patches, support less biodiversity since some organisms lack sufficient habitat and others cannot freely move as needed because of roads, parking lots, or other man-made barriers. Animals with big home ranges such as lions and other top predators, don’t do well in small patches without enough prey to sustain a large enough population (Lawrence and Fraser 2020). Norwegian ecologist John D. Linnell calculated home range sizes for Eurasian lynxes and found that protected areas in Scandinavia are mostly too small to support them. The outcome is that lynxes are preying on sheep in semi-natural forest areas, thereby affecting people’s livelihoods (Linnell at al. 2001). In contrast, organisms with broader habitat tolerances, such as pigeons, raccoons, or dingoes, may actually thrive in patches, therefore persisting in urban areas (Andrén et al. 1985).
Consider how you’d define your home range and what sorts of resources you depend on locally. What do you do when the resources you need are not available?
Species that are not native to a particular ecosystem colonize habitats all over the world. Pet Burmese pythons escaped into the Florida Everglades; American gray squirrels were deliberately released in Britain, and the emerald ash borer beetle reached the U.S. in cargo containers from Asia. These introduced species, no longer contained by their predators or parasites, often outcompete native ones for resources. Introduced species may become invasive, thriving in their new habitat free of restricting factors like specific predators or limited food supplies. Rabbits, for example, after deliberate introduction to Australia in the 1800s, became prolific and continue to damage livestock and natural habitats, despite various control efforts.
Introduced species can have particularly stark impacts on the native species of islands. For example, the biodiversity of the Hawaiian Islands changed dramatically after repeated arrivals by humans. First, Polynesians came, bringing pigs and rats to the islands. Then, cats were introduced by European explorers and colonists. The two waves of new predators fed on the eggs and hatchlings of ground-nesting birds such as geese. Before the introductions, Hawaii had at least seven species of native geese, of which only the nēnē, or Hawaiian goose (Branta sandvicensis), survives today. With no way to escape, the other six “moa-nalos” (vanished fowl) were driven to extinction by the introduced predators they were not adapted to avoid (National Park Service 2021).
The problems with introduced species are not limited to terrestrial habitats. In this diagram of invasions of nonnative marine species into other waters, what trends do you notice?
Invasive marine species are often introduced via shipping routes (Figure 4). The largest concentration of introduced species is between Africa and Asia, along the major shipping corridor called the European-Asian sea route. As humans began to travel around the world, we transported other species around, often unintentionally. Commercial shipping is implicated in an estimated 44-78% of invasions by non-native species into North American waters that either cling to ships’ hulls or ride in ballast water (stored in the hull; Elçiçek et al. 2013).
A study by Canadian marine biologist Jesica Goldsmit and colleagues assessed ecological risk based on ships discharging their ballast water at ports in the Canadian Arctic. They tallied up total ballast water discharged per year per port. They focused on three invasive species: the periwinkle snail Littorina littorea, soft shell clam Mya arenaria, and red king crab Paralithodes camtschaticus. Given shipping routes and ballast water discharges, they found that the risk of introduction of these invasives was higher for domestic ships operating within Canadian waters because they weren’t subject to ballast water inspections and reporting (Goldsmit et al. 2019).
While not all introduced species become invasive, the overall result of introduced species tends to be lower biodiversity. However, some introduced species become valuable to humans, such as earthworms in cropland soils that are mostly non-native species from Europe; the honeybees brought to the New World by English settlers; or the cattle introduced by Spaniards. The diversity of species in every part of Earth has changed dramatically over time and will continue to do so.

Global changes and biodiversity
“A species is there, and it's abundant for quite a long period of time, and then at some point it's no longer there - and so, when you look at that bigger picture, yes, you realize that either you change and adapt, or, as a species, you go extinct.”
- Kenyan paleontologist Louise Leakey, National Geographic Explorer in Residence (National Public Radio 2014).
Global change has shaped biodiversity since the beginning of life on Earth. Before humans, there were five mass extinctions, periods when biodiversity plummeted. Each mass extinction was caused by a combination of global changes, including shifts in climate, huge volcanic events, ocean current flows, and/or changes in atmospheric gases (see our Factors that Control Regional Climate module). These suites of related changes led to drastic shifts in climate and habitats all over the world. Of course, life on Earth marched on after these mass extinctions, but many species were lost forever, and new species emerged to take their place. For example, the mass extinction that included the loss of nearly all the dinosaurs was what paved the way for the diversification and dominance of the mammals.
What are some global changes occurring across Earth today?
Scientists concur that we’re in the midst of the sixth mass extinction on Earth, the first one caused by humans. The drastic changes on our planet stem from the human tendency and ability to alter our surroundings in almost every conceivable way, including water flow, temperature, nutrient cycles, forest cover, variety of plants and animals, and even the global climate. Some alterations benefit other species, but at the scale and intensity of today’s land use practices, most do not.
“Many indigenous communities rely on nature for everything – from food and water to their livelihoods and culture. Because of this intimate relationship with nature, we are the first ones to feel the impact of the climate crisis.”
- Indigenous Kichwa biodiversity researcher Johnson Cerda, 2020, Senior Director at Conservation International.
Climate change affects ecosystem conditions at all scales - from local rainfall patterns to global ocean currents. Changing conditions make habitats more or less hospitable to humans and the other species that rely on them. Indigenous Peoples, given their physical and spiritual connections to their landscapes coupled with lower capacity to relocate, are disproportionately impacted by climate change. For example, as precipitation decreases, the Western Apache Peoples encounter less robust deer and elk populations, low river levels for fishing, and scarcer water for subsistence farming (Gauer et al. 2021).
Scientists such as Italian biologist Michela Pacifici have come up with ways to assess the resilience of other species to climate changes - what range of temperatures they can tolerate, what they feed on, how fast they reproduce, and how common they are. All animals have upper thermal limits – maximum temperatures that they can tolerate. Pandas get heat-stressed in temperatures above 25˚C (77˚F; Yuxiang Fei et al. 2016), whereas some Andean iguanas can tolerate temperatures up to 40˚C (104˚F). (Guerra-Correa, 2020). Based on nearly 100 studies of plant and animal tolerances to environmental extremes, Pacifici mapped out the species most vulnerable to climate change (Pacifici et al. 2015).
In Pacifici’s map (Figure 5), where do you see concentrations of vulnerable species? Why there?
Note that vulnerable species are concentrated in the Poles, where ice is melting, and in areas near the equator, such as the Amazon, where fires are becoming more frequent. As conditions shift outside of livable ranges, organisms either move, adapt, or die, depending on their resilience to change and their ability to migrate. Thinking about how humans handle environmental changes, to what extent do the biological outcomes - move, adapt, or die - apply?
Moving to better habitat
“Expected anthropogenic climate change will redistribute the locations where specific climatic conditions favorable to the survival of a species will occur.”
- American ecologist Osvaldo E. Sala, Arizona State University
Scientists that map biodiversity by tracking the ranges of various species see evidence that many are migrating in response to climate change. Tasmanian ecologist Gretta Pecl estimates that at least a quarter of life on Earth, and possibly much more, is in the process of relocating. For example, her work shows how ocean animals like snappers, rays, and sea urchins are moving towards the South Pole as oceans warm along Tasmania’s coast. The shifts disrupt thousands of years of cultural practice by indigenous ice-fishing peoples of the region. Climate change affects not only ocean wildlife, but also the people who depend on it.
Animals migrating in response to climate change also face novel situations and threats. For example, North Atlantic Right whales have shifted their feeding routes northward in response to warming temperatures in the Gulf of Maine. In their new Gulf of St. Lawrence habitat, these whale populations suffer increased ship strikes and fishing gear entanglements. As new management plans are drafted to protect the whales, Canadian fishermen will suffer restrictions such as seasonal closures of St. Lawrence fishing areas (Meyer-Gutbrod et al. 2021).

Adapting to changing habits
When conditions change, animals may or may not have the capacity to adapt. What choices does this Arctic fox have (shown here in its winter fur) as warming weather with less snow cover increasingly changes its winter habitat to shades of brown and green?
Arctic foxes respond to seasonal changes by shedding their white winter fur and replacing it with brown fur in the spring. The change is mediated by seasonal changes in sunlight from short winter days to longer summer days. Warmer temperatures and less snow, therefore, do not provide the cues to molt to a brown coat any sooner, despite the need for camouflage (Denali Education Center 2022). Along with many other Arctic animals, adapting to climate change will require longer-term natural selection for a modified schedule of fur shedding. With climate change occuring at such a rapid pace, it is unclear if the foxes will have enough time to adapt.
When climate conditions change, some organisms can adapt. American Pikas, with naturally high body temperatures, prefer cooler habitats. Originally from Asia, pikas spread into North America five million years ago when the climate was cooler. Over geologic time, pikas have retreated to high mountains in the western U.S. and Canada. During hot weather, they stay cool by taking refuge in the shade of rock piles. There may come a tipping point when temperatures in the rocks rise beyond what pikas can tolerate, forcing them to migrate or go extinct, but for now they appear to be adapting (Smith 2021).
Cold-blooded animals (ectotherms), such as insects or lizards, may have an advantage in adapting because of their ability to tolerate more extreme temperatures. Ectotherms rely on outside temperatures to regulate their body temperature, hence their name (ecto = outside; therm = heat). Many have mechanisms to avoid freezing, like natural antifreeze chemicals in their blood. As the climate warms, some insects benefit from higher metabolisms and increased reproduction, which may lead to unpredictable shifts in populations of pollinators and crop pests (Gérard 2020; Deutsch 2018).
Still, the immediate advantages of high temperatures do not ensure long-term gains. Portuguese marine biologist Carolina Madeira used sea snails (Stramonita haemastoma) to examine short versus long-term impacts of temperature in a laboratory setting. She found that the snails could acclimate to higher water temperature over short periods, but grew more slowly from the thermal stress. Insects and other ectotherms can usually adapt to natural cyclical variations in global temperatures, but the current temperature increase is occurring on a much faster time scale (Madeira et al 2018).
Generally, any species will have a threshold beyond which temperatures are intolerable, forcing individuals to migrate or die. Not all species have the ability to migrate. A study by Colombian biologist Cristian Román Palacios modeled whether animal and plant species could survive climate change by migrating. The model, which included over 500 animal and plant species, indicated that if migration is the only option, more than 50% of them face extinction. But, taking into account adaptations like the pikas finding cooler refuges, the percentage facing extinction is closer to 30% (Román-Palacios and Wiens 2018). Whether a particular species adapts, migrates, or goes extinct in response to climate shifts will depend on the amount of change in relation to its capacity to adjust its habits or range.
Failing to move or adapt
For those species that do not succeed in adapting or migrating, climate changes and other sustained global changes can be fatal. As climate continues to warm on Earth, biodiversity is expected to plummet (see our Factors that Control Earth's Temperature module). For example, American biologist Barry Sinervo estimated that climate change could wipe out 80% of the world’s lizard species by 2080 (Sinervo et al. 2010).
As habitats continue to change globally, we face big questions about how biodiversity will change. Which species can adapt by adapting or moving? Which species will go extinct? As climate warms, we can expect to see increasing disruptions in how ecosystems function across the globe. The Fourth National Climate Assessment predicts more frequent and severe storms, droughts, erosion, and flooding. Each of these disruptions may cause significant changes to biodiversity (see our Environmental Services and Economics module).

Biodiversity in the anthropocene
The Anthropocene, or “Age of Man”, is what scientists call the current period of dramatic Earth changes caused by human activities. When the Anthropocene began is debatable, but its long-term impacts are clear. Habitats have been altered, ecosystems are functioning differently, and biodiversity is lower. Earlier humans, with lower densities and less intensive resource exploitation, altered the landscape in ways that allowed other species to persist. Modern human practices leave little ecological room for other species (Figure 7).
Thinking about the bicycle again, some other species (parts) are missing, leading us to suspect that its essential systems of brakes or steering might not work. You are riding the bicycle anyway because it's the only one you've got, as we are living on Earth despite the lost species. You may find it more difficult to ride with so many of the parts missing, and the bike may not last as long as it would have with all of its parts intact.
The upkeep and repair of the bicycle that is Earth is in our hands. Recognizing that the sustainability of Earth for living organisms, including humans, is at stake, people around the world are working to maintain biodiversity.

What Is Vertical Farming? Everything You Should Know About This Innovation
It’s no secret that the future of agriculture is concerning and needs a change. Overall, the population is growing at about 1 percent per year, even faster in some countries. Feeding this growing population is sure to be a challenge as time progresses.
Adding to the problem, current and former agricultural practices are incredibly harmful to the planet. Agriculture has been implicated as a driving cause of climate change, deforestation, and soil degradation. The problem is so significant that we’ve lost a third of our arable land over the past 40 years.
We must find better ways of producing food for future generations. Fortunately, new farming technology, such as vertical agriculture, offers an excellent way to meet these challenges and produce the food needed for future generations.
What is Vertical Farming?
Vertical farming is exactly what it sounds like: farming on vertical surfaces rather than traditional, horizontal agriculture. By using vertically stacked layers, farmers can produce much more food on the same amount of land (or even less).
Often these layers are integrated into buildings such as skyscrapers, housed in warehouses or shipping containers, greenhouses (like ours), or placed in spaces that would otherwise be unfit for farming.
Yet vertical farming is much more than just stacking plants and hoping for the best. The practice requires artificial temperature, light, water, and humidity control. If a delicate balance is not maintained, it’s possible to lose an entire crop the way a traditional farm might in the event of a drought or flood.
The History of Vertical Farming
It’s easy to think of vertical farming as a new concept, especially considering the high-tech vertical farming companies emerging today. But the ideas behind the practice go back millennia. The first example of vertical farming known today is that of the Babylonian Hanging Gardens around 2,500 years ago.
Even hydroponic farming is not entirely new. Around a thousand years ago, the Aztecs developed a version of this practice, called chinampas, by growing their plants on rafts floating above rivers and lakes.
A more technologically advanced form of vertical farming popped up in the 1600s. French and Dutch farmers developed ways to grow warmer-climate fruits against stone walls that retained heat, creating their own microclimates.
How Does Vertical Farming Work?
Vertical farming may answer many of agriculture’s challenges, such as providing us with more food on less land and doing so sustainably. But how do vertical farms work, exactly?
Several vertical agriculture models are available, from patio gardens built into old pallets to warehouses with stacked trays and greenhouses (like ours) that produce food for entire communities. Here are the details on how Eden Green Technology’s hydroponic greenhouses work.
Our hydroponic vertical farming technology allows growers to cultivate crops in stacked plant spots within tower-like structures. These patented towers are hydroponic systems designed to produce the perfect micro-climate and enable farmers to grow their crops year-round.
Our vertical hydroponics are designed to provide crops with access to natural sunlight so they grow with less waste of land, water, and energy. And our state-of-the-art sustainable system allows you to control all aspects of your farm. This includes production tools that will help you optimize crop cycles and produce plenty of yields to meet your needs.
The Benefits of Vertical Farming
Vertical farming has many benefits, with this model providing maximum output with minimal environmental impact and far less space required. With resources at a premium, it will become increasingly difficult to maintain food production using traditional methods.
Utilize Less Water & Space
With vertical farming techniques; farmers can use 98 percent less water and 99 percent less land. They can produce crop yields of 240 times that of traditional farms through year-round rolling or perpetual harvest. All of our produce is powered by the sun rather than LED lights, so these crops are not reliant on fossil fuels or other less ideal energy sources.
By 2050, around 80 percent of the world's population will live in urban areas. This population structure will mean a higher demand for food in the areas where land is the hardest to come by. In these large urban centers, vertical farming offers a way to meet this increased demand for food without the need for vast fields.
Increased Production All Year
Vertical farming also offers increased production overall and consistent year-round production. Gone are the days when some fruits and vegetables were only available seasonally. Instead, vertical farms can produce all sorts of crops year-round with little dependence on weather or climate.
Controlled Environment Agriculture (CEA) Eliminates Environmental Impacts
Indoor vertical farming often includes a practice called Controlled Environment Agriculture, or CEA. CEA involves a series of technologies designed around providing optimal conditions for plants. It controls factors like temperature, lighting, and humidity to allow farmers to grow plants that would otherwise not be suitable for the climate and weather.
There are several benefits to a CEA setup. CEA can significantly lessen the occupational hazards associated with traditional farming. Indoor farming does not allow access to wildlife, eliminating the conflict between farmers and native species. It doesn’t expose farmers to hazards and diseases such as malaria, poisonous chemicals, and other life-threatening challenges. And with no hazardous chemical runoff, farm-adjacent communities are also protected.
According to EcoWatch, vertical farms are the way of the future:
If you’re interested in this topic, we wrote an article on how vertical farming helps to prevent farming diseases.
Food Desert Solution
Finally, vertical farms can solve the increasing problem of food deserts in heavily populated areas that lack access to fresh foods such as fruits and vegetables.
Because vertical farms can be constructed with a small footprint and can even be integrated into existing buildings and rooftops, vertical farming has already started to produce food oases where deserts once existed.
This provides healthy food where only unhealthy options were previously available. Because it doesn’t require a lengthy shipping and warehousing process, it can also produce affordable and nutritional food for low-income families.
Reduced Arable Land
With arable land quickly depleting due to erosion and pollution, we’re heading toward a crisis. We must find ways to produce healthy food without needing acres and acres of quality topsoil. Vertical farming can help contribute to this solution by farming upward rather than outward.
Since many vertical farms are contained within greenhouses or other structures, they can be built nearly anywhere — in densely populated urban centers, on rooftops and inside warehouses, or even in depleted areas where traditionally farmed crops can no longer grow.
CEA vertical farms typically have little need or even use for pesticides. By controlling the environment around crops, these systems keep out pests naturally – no need for chemical pesticides that can cause other problems down the line.
Since vertical farms can be constructed in urban areas; this reduces how far produce travels between farms and grocery stores, lowering their carbon footprint. This also means fewer food miles and fresher produce reaching your local grocer. When food is grown mere miles from where consumers will eat it, it stays fresher longer, creating less food waste and offering fresher, healthy food for local families.
Food recalls are a common occurrence. We’re always hearing about produce tainted by E.Coli or other pathogens.
Vertical farming virtually eliminates this problem by carefully monitoring and controlling the environment around plants, creating near laboratory conditions and preventing farming diseases. In such an environment, the introduction of contaminants is far less likely.
Can Vertical Farms Feed the World?
Vertical farming is an amazing option to solve many of agriculture’s problems today, but it’s not a complete solution. Some crops simply won’t grow well in such a configuration, and there will always be a need for other growing methods.
That said, vertical farms can help feed the world by allowing growers to produce healthy, fresh foods in areas with little food production. They can offer ways for farmers to produce crops without worries over the effects of climate change since CEA systems allow for any climate the plants might need. And they can grow more food in less space, allowing us to continue to feed the growing population.
Vertical Agriculture With Eden Green Technology
There are a great many reasons to adopt vertical farming techniques today. Possibly the most important reason is that without them, we may not be able to produce adequate food to feed the world’s growing population. Yet this new farming method may seem overwhelming to those who are not well versed in it.
Fortunately, Eden Green Technology takes the hassle out of vertical farming by building, running, and harvesting produce for grocers and store brands. You tell us what you want, how much you want, and we will grow it for you. While other vertical farms put their label on packaging, we specifically offer private label options so you can represent your brand.
The Future of Indoor Vertical Farming
You don’t have to look very far to find predictions about the future of agriculture. Many believe vertical farming could be a significant portion of the picture of future agriculture. As AgTech continues to develop, farms are becoming increasingly high-tech, allowing farmers to produce more, pollute less, and meet the challenges facing us as we move into the future.
Vertical farms will also likely become more technologically advanced. This may mean robotic monitoring and harvesting, AI-powered CEA systems, and much more. One thing seems sure; vertical farms will likely become a lot more common as we seek to meet the challenges before us.
Frequently Asked Questions About Vertical Farming
Is Vertical Farming Efficient?
Vertical farming uses less water and less space and increases production throughout the year rather than being tied to a specific season. An Eden Green Technology farm can produce daily harvests all year long, with less than 3% food waste and the option to grow more than 200 varieties of hydroponic produce in a single facility.
Profitability is one of the greatest difficulties in some vertical farming models. When starting a vertical farm, it’s essential to ensure you have the right technology and partnership for a profitable venture. Energy used for grow lights is among the most concerning vertical farm expenses. Systems like Eden Green Technology seek to minimize these costs while producing plentiful crops for sale.

National qualifications system
The national qualifications system includes, by definition, all aspects of a country's activity related to the recognition of learning and other mechanisms that combine education and training with the job market and civil society. It should include the development and implementation of institutional devices and processes for quality assurance, assessment and qualifications awarded. It can be made up of different subsystems and include the National Qualifications Framework and National Qualifications Catalogue (CNQ) as tools that help structure such qualifications.
In Portugal, the National Qualifications System (Sistema Nacional de Qualificações - SNQ) began with the Council of Ministers Resolution No 173/2007, 7 November. In the same year, among others, it defined objectives such as promoting upper secondary level education as a minimum qualification for the population and the investment in dual certification, both via the increase in VET provision and the recognition, validation and certification of formal, informal and non-formal learning competences.
In terms of adults, it aims to further develop a system for improving adult qualifications, using various tools, particularly the mechanisms for the recognition, validation and certification of competences acquired throughout life in formal, informal and non-formal contexts and for vocationally oriented training that the workforce can attend.
As part of the implementation of national education and training policies, the SNQ (Decree-Law No 396/2007, 31 December, as last amended by Decree-Law No 14/2017, 26 January) includes a set of structures and mechanisms that ensure the relevance of education and training to personal development and for the modernisation of enterprises and the economy.
For these aims to be operational and regulated, the SNQ boasts the following structures:
- various public bodies (National Agency for Qualification and Vocational Education - ANQEP, I.P.; Directorate-General for Education - DGE; Directorate-General for Employment and Labour Relations - DGERT; and Institute for Employment and Vocational Training - IEFP, I.P.).
- bodies and structures with responsibilities in education and vocational training policy funding.
- specialised adult qualification centres, currently called Qualifica Centres.
- a network of training bodies, made up of a) basic and upper secondary education establishments; b) vocational training and vocational retraining centres managed directly or via protocols; c) private training bodies certified by Directorate General for Employment and Labour Relations (Direção-Geral do Emprego e das Relações de Trabalho - DGERT); d) training bodies that are part of other ministries or other legal persons governed by public law; e) private and cooperative schools with parallel teaching or recognition of public interest; f) public and private vocational schools; f) bodies with certified training structures in the private sector.
- a network of 18 Sector Councils for Qualifications (Conselhos Setoriais para a Qualificação - CSQ), which functions as a platform for technical-consultative discussion and reflection. Divided into sectors and following a set of structural/delimitation principles, it aims to identify the essential qualifications for competitive and modern production and the personal and social development of individuals. This network is made up of:
- specialists appointed by the government department that oversees the sector of activity covered by the CSQ
- regulatory bodies for access to and the exercise of professions and professional activities
- social partners
- direct management professional training centres and IEFP, I.P. invested vocational training centres
- public, private and cooperative educational establishments (including vocational schools, training bodies and Qualifica Centres, particularly those with sectoral or regional specialisation)
- technological, innovation and research and development centres
- top companies and business groups
- competitiveness clusters
- prestigious national and international independent experts, among others who support the ANQEP, IP in the processes of updating and developing the catalogue.
The system is made operational and regulated by:
- The National Qualifications Catalogue (Catálogo Nacional de Qualificações - CNQ) which is concerned with the strategic management of the non-higher education qualifications necessary and critical for the competitiveness and modernisation of companies and the productive sector, as well as for individuals’ personal and social development. The CNQ aims to ensure greater coordination between the competences required for the country’s socioeconomic development and the training provision available within the National Qualification System.
- The CNQ offers dual certification and includes a set of academic and professional reference frameworks for each qualification. It also includes short and medium-length pathways that are considered key to the country’s development. This tool is permanently open to improvements or new qualifications proposed by the sector councils for qualification operating, or ANQEP, IP itself. The design of these reference frameworks and assessment tools is based on the new qualification design methodology, which is published on the National Qualifications Catalogue website. In 2022, the CNQ began an updating process to make it more focussed on competences and learning outcomes. This process involves 21 diagnostic studies on the skills and qualifications needed for different sectors, as well as the design of the respective competence reference frameworks, training reference frameworks and assessment tools used for the recognition, validation and certification of skills acquired through work experience (Professional RVCC).
- The National Qualifications Framework (QNQ), which is regulated by Ordinance No 782/2009, 23 July, classifies the qualifications produced in the education and training system according to a set of areas , defining the structure of the qualification levels, including access requirements and the corresponding school qualification. The QNQ includes eight qualification levels covering qualifications at the various levels of the education and training system, regardless of the access routes (basic, upper-secondary, higher education, vocational training and processes of recognition, validation and certification of competences. The QNQ also adheres to the principles of the European Qualification Framework (EQF) in relation to the description of national qualifications in terms of learning outcomes, according to the descriptors associated with each qualification level. In addition to the clarity and transparency that it gives the entire system and the coordination of operators’ activity at national and European level, it is a key factor in the transition to an education and training system geared towards knowledge, competences and attitudes that determine and demonstrate the competences associated with each qualification level.
- The National Credit System for Vocational Education and Training (regulated by Ordinance No 47/2017, 1 February) attributes credit to dual certification qualifications within the QNQ and included in the CNQ. It does the same with other certified training not included in the Catalogue, provided that it is registered with the Information and Management System of the Education and Training Provision (Sistema de Informação e Gestão da Oferta Educativa e Formativa – SIGO) and complies with the current quality assurance criteria. The credit points of a qualification and its constituent units are obtained when trainees achieve the learning outcomes or demonstrate the competences these units refer to, i.e., when they obtain certification in the respective qualification units. This system permits the accumulation and transfer of credit, in accordance with the principles of the European Credit System for Vocational Education and Training (ECVET), by promoting mobility within Europe.
- The Qualifica Passport is a personal electronic, non-transferable and optional document that contains the individual record of competences acquired and training attended by citizens, throughout their life, which are referred to in the National Qualifications Catalogue. It also includes of vocational training courses not included in the National Qualifications Catalogue, which presupposes successful completion. It allows the holder to identify areas where they can acquire and/or refine competences that improve their qualification pathway, as well as offering employers a more immediate evaluation of a candidate’s suitability for a specific job.
Information and management system of the education and training provision
Other structural mechanisms were created to ensure the system is supervised, monitored, assessed and regulated, such as the Information and Management System of the Education and Training Provision (SIGO). This is a computer platform accessible to system operators and coordinators that includes educational and vocational qualifications provision divided between the different bodies of the Ministry of Education and the Ministry of Solidarity, Employment and Social Security. This constitutes significant progression in terms of the clarity of available provision, administrative simplification and the use of the platform to launch, supervise, monitor and manage provision.
SIGO is designed to meet the information needs of schools, training centres, the Directorate-General of School Administration, DGEstE, IEFP, IP and ANQEP, IP, which also use the information system for needs associated with their specific mission.
Statistical data of the national qualifications system
Based on the impact of the measures created via the National Qualifications System (SNQ), it is important to examine a set of statistical indicators.
National qualifications catalogue and sector councils for qualifications
In 2008, when it was launched, the National Qualification Catalogue (CNQ) included 238 qualifications, 60 of which had reference frameworks for the recognition, validation and certification of professional competences (RVCC).
Considering the data updated in 2023, the CNQ includes 392 qualifications with 176 RVCC reference frameworks created. Total qualifications include 110 Level 2 qualifications, 231 Level 4 qualifications and 51 Level 5 qualifications. This growth involved the creation of 207 new qualifications, the exclusion of 48 and 1,213 updates.
The CNQ also includes a number of short and medium-length courses related to different programmes or emerging areas of intervention, such as: Young + Digital Programme, which focusses on digital skills; Portuguese as Host Language, which is geared towards citizens whose mother tongue is not Portuguese and/or who do not have basic, intermediate or advanced skills in Portuguese; Digital Skills Certificate Programme, which aims to boost the Portuguese population’s digital skills; Train Driver, which is designed to help individuals obtain and renew locomotive and train licences; the Qualification for Internationalisation Programme, which aims to train human resources in internationalisation and international trade; the "Valorizar Social" Programme, which aims to increase management and digital skills as a factor for inclusion, as well as boosting the transformation and adaptation of social institutions to today's world and the new challenges that they face on a daily basis; Green Skills & Jobs, which provides vocational training and retraining for the unemployed and workers in companies and other employers that are directly or indirectly affected by increases in energy costs, and for the unemployed, job retention and creation by speeding up the transition and energy efficiency.
A new short- and medium-term taxi driver qualification was introduced in 2023. This offers access to the profession of driver of light passenger vehicles for public transport, known as the Taxi Driver Certificate (CMT).
In this process of renewal and updating of reference frameworks, the role of the sector councils for qualifications (Conselhos Setoriais para a Qualificação - CSQ) is essential.
The qualification needs forecasting system (SANQ)
Law No 82A/2014, 31 December, which approved the Major Planning Options for 2015, highlighted the importance of skills needs analysis system for the country.
The qualification needs forecasting system (Sistema de Antecipação de Necessidades de Qualificações – SANQ) was created within this context and stemmed from ANQEP's need to have access to the most up-to-date knowledge regarding the supply and demand for qualifications (short and medium-term) and developments in education and training provision.
As such, the definition and development of a skills needs forecasting model was an important step in consolidating a more informed and sustained intervention regarding planning and cooperation of the training network.
The SANQ model is based on three modules (a basic diagnostic module, planning module and regional development module). These form a chain and are based on a set of methodological tools - both quantitative and qualitative - that allows a forecast of how employment and skill needs change and relate to education and training provision. SANQ’s main operational objectives are the following:
- an initial macro analysis - with information on the economic and job market dynamics that influence demand for skills (in the short and medium-term).
- the identification of potential future skills, and the need for adjustment to existing ones, allowing the National Qualifications Catalogue to be updated.
- the definition of skills needs regional assessments.
- the identification of priority career areas and prospects, both nationally and regionally, to support the education and training provision network planning process.
The objective was to construct a dynamic forecasting model, which would update information continuously, supporting the decision-making of the different stakeholders in the National Qualification System, such as:
- young people or adults looking to do a qualification, who could use the SANQ to see opportunities in the different regions;
- guidance, information and referral services and professionals, who would have another tool to help young people and adults decide on qualifications that match their expectations;
- education and training providers who could use SANQ to plan future provision;
- the bodies that establish criteria defining the training provision network (ANQEP, IP, DGEstE and IEFP, IP), as well as those responsible for funding the different types of qualification access (such as the thematic or regional community funds management programmes as part of Portugal 2030 Strategy, or the management of investments for Component 6. Qualifications and Skills - Recovery and Resilience Plan).
As part of the planning process for the dual certification provision network for young people (vocational courses and education and training courses), SANQ has been able to identify priority career areas and prospects, both nationally and regionally. Although it is based on a diagnosis of skills needs for the mainland at NUT II level (basic assessment), since the outset, the SANQ model foresees a "regional development module" that helps define skills needs at regional level (developed and coordinated by intermunicipal communities or metropolitan areas), providing a regional dimension to the definition of priorities regarding how education and training provision for young people is organised.
Based on SANQ results, every year ANQEP, I.P. defines criteria for the dual certification provision network for young people (vocational courses and education and training courses), which supports the planning and coordinating process for these networks.
After its creation and first use for planning provision for the 2015/16 school year, ANQEP updated SANQ’s basic diagnostic module in 2017, with the results used to plan provision for the following school years (2018/19, 2019/20 and 2020/21) and in 2020 (reflected in the 2021/22, 2022/23 and 2023/24 school years). In 2023, the basic diagnostic module was updated, which will support the process of regional development and network planning for future school years.
In 2016, ANQEP provided all intermunicipal communities and metropolitan areas with the Regional Development Toolkit, which offers the possibility of sub-regional application of the business survey, as well as the tools necessary to collect qualitative information.
The model’s usefulness is based on the regular updating of the information that supports both basic diagnosis and regional development, so that the monitoring of recruitment trends, as well as qualifications and skills needs, is possible and contributes to the planning of dual certification provision networks and the update of the National Qualification Catalogue.
Intermunicipal communities’ and metropolitan areas’ (IC/MA) participation in the regional development of qualifications needs assessment and local conciliation of the provision network is a key aspect of SANQ and the planning strategy for dual certification provision.
This participation has gradually increased since the launch of SANQ, with all 23 IC/MA participating since the 2023/24 school year. The growing involvement of the IC/MA in the process of local consultation of offers over the years has also been accompanied by an increase in their capacity during the regional development phase.

What is a Language Service Provider (LSP)?
In our increasingly interconnected world, the ability to communicate across linguistic barriers is more crucial than ever. This is where Language Service Providers (LSPs) come into play, serving as the vital bridge between languages and cultures.
But what exactly is an LSP?
The Role of LSPs in Global Communication
An LSP, or Language Service Provider, is a company that offers a suite of language-related services to facilitate communication in multiple languages. These services range from translation and interpreting to localization and even cultural consulting. LSPs play a pivotal role in global communication, enabling businesses to expand their reach, governments to disseminate information, and individuals to connect across linguistic divides.
The definition of an LSP is not limited to translation alone; it encompasses a broad spectrum of language services that cater to various industries and sectors. Language service provider companies have become integral to international trade, healthcare, legal proceedings, education, government, manufacturing, and technology. They ensure that language barriers do not impede progress or access to services and information.
The Evolution of LSPs with Globalization and Digitalization
The concept of LSPs is not new, but their importance has grown exponentially with globalization and digitalization. As businesses pursue international markets, the demand for language solutions that can adapt products, services, and content to local languages and cultures has surged. This evolution has transformed traditional translation companies into comprehensive language service providers.
Digitalization has further expanded the role of LSPs. With the advent of the internet, mobile technology, and social media, the need for website localization, technical manual translation, and certified document translation has skyrocketed. LSPs have adapted by incorporating technology into their workflows, utilizing translation memory software and other tools to enhance efficiency and accuracy.
The Services an LSP Might Provide
LSPs offer a wide array of services to meet the diverse needs of their clients. Let’s explore the different types of services you might expect from a top-tier language services company.
At the core of any LSP’s offerings are translation services. These are not just about converting text from one language to another; they involve adapting the material to resonate with the target audience culturally and contextually.
Document translation is the backbone of language translation agencies. It involves the translation of written materials such as contracts, brochures, and reports. The use of human translators, either in place of or in addition to A.I. translation tools, ensures that the meaning and tone of the original document are preserved. Human translators are vital component in delivering translations that are both accurate and culturally appropriate.
Localization for Websites and Other Marketing Content
In the digital age, a company’s website is often the first point of contact with potential customers. Website localization goes beyond mere translation; it’s about adapting your website’s content, design, and functionality to suit different linguistic and cultural norms for each target market.
Additionally, marketing messaging on social media, marketing emails, blog posts, print articles, etc., must be culturally appropriate for their target audience. Machine translation has yet to achieve this level of cultural fluency.
Technical Manual Translation.
Technical manual translation is a specialized service that requires not only linguistic skills but also technical expertise. It is important that your LSP’s translators are well-versed in the specific technical terms and concepts of various industries, ensuring that technical manuals are accurately translated and easily understood by users in different languages.
Certified Document Translation.
There are instances when the accuracy of a translation must be established in a legal proceeding. Some translation solution companies offer certified document translation services. This means they will confirm the translation’s accuracy if needed for a legal proceeding, up to and including testifying in court.
Interpreting is another critical service provided by LSPs, facilitating real-time communication between speakers of different languages.
Modes of Interpreting
- Simultaneous interpreting: This mode is often used in conferences, courtrooms, classrooms, and large meetings. Interpreters translate the spoken word in real-time, without waiting for the speaker to pause.
- Consecutive interpreting: In this mode, the interpreter waits for the speaker to pause before translating segments of speech. It’s commonly used with smaller groups, and in settings like medical appointments or legal consultations.
Methods of Interpreting
- In-person interpreting: The most effective method of interpreting, in-person interpreters physically attend the location where their services are needed. This ensures the highest level of accuracy and rapport between the interpreter and communicating parties.
- Video Remote Interpreting (VRI): VRI is a convenient solution for situations where in-person interpreting is not feasible. These services connect you with an interpreter through a video call, and can typically be scheduled in advance or provided on-demand.
- Over-the-phone interpreting (OPI): Essentially a conference call in which one of the parties is an interpreter, OPI is a fast an economical method of reaching an interpreter. It is commonly used by call centers, reducing the need for multiple language queues.
American Sign Language
One of the highest demand types of interpreting is iTi is American Sign Language (ASL). This visual language requires a high level of expertise and training, and remains one of the most called-for forms of interpreting. ASL fulfills federal and state requirements for accommodations for the Deaf and Hard of Hearing.
Beyond translation and interpreting, a language service provider may offer a range of additional services to meet the comprehensive needs of its clients.
Transcription and Translation
Transcription involves converting audio or video content into written text. Law firms and government agencies are common users of this services, where accurate transcription and translation of interviews and depositions are vital.
Subtitling and Voiceovers
Subtitling and voiceover services make audiovisual content accessible to a global audience. From training videos to marketing content, adding subtitles and voiceovers can expand the size of an organization’s video library with one step.
To see how A.I. measures up against human interpreters in accurately subtitling audiovisual content, see our post: Will A.I. Replace Human Interpreters?
Language Proficiency Assessments
To ensure effective communication, some LSPs offers language proficiency assessments that evaluate an individual’s ability to speak, understand, write, and read in a specific language. This is particularly popular in the healthcare sector, to determine where bilingual staff are qualified to have medical conversations with patients and families in languages other than English.
Community Interpreter Training
In the U.S., a national standard exists to qualify a professional interpreter to become a Community Interpreter. This requires a 40-hour training course that includes education in skills, standards, and professional ethics.
Some LSPs offer Qualified Medical Interpreter Training courses, which adds training in medical terminology and additional considerations specific to the healthcare industry.
See our 2022 article Should My Bilingual Employees Act as Medical Interpreters? for an in-depth discussion on this topic.
CART and C-Print
CART and C-Print services are accommodations for deaf and hard-of-hearing people that are legally recognized. CART provides word-for-word subtitles of spoken words, while C-Print offers more summarized notes. Both help with understanding spoken information.
These services are useful for people who have difficulty understanding spoken English. They also have the advantage of creating a written transcript of speeches, webinars, meetings, and panel discussions.
Multilingual Desktop Publishing
Multilingual desktop publishing services ensure that your translated documents are not only linguistically accurate but also visually appealing for the target audience. This may require, changing the format, images, and design of the original material in order for the message to resonate with a different culture.
What is a Language Access Plan?
A Language Access Plan or Program is a comprehensive approach designed to ensure that individuals who do not speak English as their primary language have equal access to services and information. It’s a strategic framework that organizations implement to address and remove language barriers, enabling effective communication with non-English speakers.
Organizations with a serious commitment to diversity, equity, and inclusion (DEI) will often implement a comprehensive language access plan. This is especially common in healthcare organizations.

Explanation of Language Access Plans
Language Access Plans are tailored to the specific needs of an organization and the communities it serves. They typically include policies, procedures, and practices that identify language needs, determine how to respond to those needs, and ensure that language services are available and easily accessible. These plans are crucial for organizations that interact with diverse populations, including government agencies, healthcare providers, educational institutions, and businesses.
Legal Requirements for Language Access in Various Sectors
In many countries, there are legal requirements for language access, particularly in sectors that receive federal funding or are subject to anti-discrimination laws. For instance, in the United States, Title VI of the Civil Rights Act of 1964 prohibits discrimination based on national origin, which includes language. This means that organizations must provide language assistance to ensure meaningful access to their programs and services.
The Americans with Disabilities Act (ADA) requires accommodations for the Deaf and Hard of Hearing, and both ASL interpreting and CART and C-Print services ensure compliance with this requirement. For healthcare organizations, the Affordable Care Act (ACA) requires the availability of interpreting and translation services for limited English proficient (LEP) patients and their families.
Similar legal frameworks exist in other countries, reflecting the global recognition of the importance of language access.
The Benefits of Having a Language Access Plan or Program
Enhancing Communication with Non-English Speakers
By implementing a Language Access Plan, organizations can significantly enhance communication with non-English speakers. This leads to better understanding, fewer errors, and more efficient service delivery. It’s not just about translating words; it’s about conveying meaning and intent, which is essential in building trust and rapport.
Improving Customer Satisfaction and Loyalty
Organizations that provide language services often see improvements in customer satisfaction and loyalty. When clients feel understood and valued, they are more likely to return and recommend the services to others. This is particularly true in industries like healthcare and legal services, where clear communication is paramount.
Expanding Into and/or Becoming More Competitive in a Global Market
A Language Access Plan can be a key differentiator in a global market. It allows organizations to expand their reach and tap into new customer bases. Moreover, it demonstrates cultural sensitivity and global awareness, traits that are highly valued in today’s competitive landscape.
Compliance with Legal and Ethical Standards
Adhering to legal and ethical standards is another compelling reason to have a Language Access Plan. It ensures compliance with laws such as the Americans with Disabilities Act (ADA), reducing the risk of legal challenges and penalties. It also aligns with ethical principles of equity and inclusivity, reinforcing an organization’s commitment to serving all members of the community.
The Advantages of a Single Provider over Multiple Providers
- Streamlined Communication and Consistency with a Single Provider. Working with a single language service provider (LSP) offers streamlined communication and consistency. A single provider becomes familiar with an organization’s specific terminology, preferences, and processes, leading to more cohesive and reliable language services.
- Improved/More Transparent Reporting and Billing. A single LSP can provide improved and more transparent reporting and billing. With a consolidated view of language services, organizations can track usage, outcomes, and expenditures more effectively, leading to better decision-making and budget management.
- Savings Because of a Preset Schedule of Fees – a Language Services Agreement (LSA). An LSA with a single LSP can result in savings due to a preset schedule of fees. Organizations can negotiate favorable rates and terms, benefiting from volume discounts and avoiding the administrative costs associated with managing multiple vendors.
- Time Savings. With a single provide, an organization always knows who to contact for any language service need. By having a preset schedule of fees, the need for individual quotes and contracts is bypassed, reducing turnaround time for translation projects and allowing for last-minute and on-demand interpreting sessions.
What to Look for in a Language Service Provider
Expertise and Experience in Relevant Industries
When selecting an LSP, it’s important to consider their subject matter expertise and experience in relevant industries. An LSP like iTi, with a proven track record in sectors such as healthcare, legal, and government, can provide services that are not only linguistically accurate but also industry-specific.
Quality Assurance Processes and Certifications
Quality assurance processes and certifications are indicators of an LSP’s commitment to excellence. Look for providers that have rigorous quality control measures in place and hold industry-recognized certifications.
Certifications from organizations such as the American Society for Testing and Materials (ASTM) and the International Organization for Standardization (ISO) indicate that the LSP has passed rigorous standards for QA and customer satisfaction.
Reputation for Customer Service Excellence and Personal Attention
A reputation for customer service excellence and personal attention is crucial. An LSP that is responsive, attentive, and dedicated to meeting client needs will contribute to a successful partnership.
Customization of Language Services Plans Based on Organization’s Size and Needs
The ability to customize language services plans based on an organization’s size and needs is a valuable trait in an LSP. Whether it’s a small business or a large corporation, the LSP should be able to tailor its services to fit the client’s unique requirements.
Technological Capabilities for Modern Language Services
Technological capabilities are increasingly important in modern language services. An LSP that leverages the latest technology can provide more efficient, accurate, and innovative solutions.
Availability of Certified Document Translation
Certified document translation is a must-have service for many organizations, especially those involved in legal proceedings or international business. Ensure that the LSP offers certified translations that meet the necessary standards.
Number of Languages Available
The number of languages an LSP offers is another consideration. A provider with a wide range of languages can serve as a one-stop-shop for all your language needs.
Hours/Days Interpreting Services Are Available
Finally, consider the availability of interpreting services. An LSP that offers extended hours or 24/7 availability ensures that you have access to interpreters whenever you need them.
The Top LSPs in the U.S.
The landscape of language service providers (LSPs) in the United States is both vast and dynamic, with companies of various sizes catering to a multitude of language needs across different sectors. These top LSPs are characterized by their comprehensive service offerings, commitment to quality, and innovative approaches to overcoming language barriers.

How Much Sun Does Basil Need?
Understanding the Sunlight Requirements of Basil Plants
Basil is a popular herb in many culinary traditions around the world. Its bright and refreshing flavor adds a delightful touch to countless dishes, making it a staple in home gardens and professional kitchens alike. When it comes to growing basil, proper sunlight is essential for its health and productivity. So, how much sun does basil need?
Basil is a sun-loving herb that thrives in warm and sunny conditions. It requires a minimum of 6 to 8 hours of direct sunlight each day for optimal growth and development. Without adequate sunlight, basil plants may become weak, leggy, and prone to disease.
Full sun exposure allows basil to photosynthesize efficiently, producing the sugars and energy it needs to grow and produce flavorful leaves. In addition to sunlight, basil also requires well-draining soil and regular watering to thrive. However, it is important to note that too much direct sunlight, especially during the scorching midday hours, can also be detrimental to basil’s health.
Basil is known to be a heat-loving herb, but it is crucial to protect it during the hottest parts of the day. Intense heat and direct sunlight can cause the leaves to wilt and scorch, affecting their flavor and overall quality. Providing some shade during the peak hours of sunlight can help prevent damage and maintain the plant’s vigor.
When planting basil in your garden or containers, choose a sunny location that receives ample sunlight throughout the day. An east or west-facing spot is typically ideal as it provides morning or afternoon sun, respectively, while avoiding the harsh midday rays. If growing indoors, place your basil plants near a south-facing window where they can receive maximum sunlight.
It’s important to note that while basil requires full sun to thrive, it can tolerate light shade for a few hours each day. If your garden has areas with partial shade, you can still successfully grow basil, albeit with slightly slower growth and potentially less robust flavor. Adjustments like using stakes or bamboo trellises can also help position the plants to receive optimal sunlight.
Basil needs a minimum of 6 to 8 hours of direct sunlight each day to thrive. While it is a sun-loving herb, it is important to provide some shade during the hottest parts of the day to prevent sunburn and maintain the plant’s vitality. By understanding the sunlight requirements of basil plants and providing the right conditions, you can enjoy a bountiful harvest of aromatic, flavorful basil leaves for all your culinary creations.
Ideal Light Conditions for Basil Plant Growth
When it comes to growing basil, providing the right amount of light is crucial for its overall health and productivity. Basil is a sun-loving herb that thrives in warm and sunny conditions. That said, it’s important to understand the ideal light conditions for basil plant growth to ensure its success in your garden or indoor space.
Generally, basil plants require full sun to thrive. This means they need exposure to direct sunlight for at least 6 to 8 hours a day. Full sun refers to a location that receives the maximum amount of sunlight throughout the day, without any obstructions such as shade from buildings or trees.
When choosing a spot to grow basil, consider the natural sunlight patterns in your area. South-facing locations often receive the most sunlight, making them ideal for growing basil. However, east or west-facing spots can also provide sufficient sunlight. It’s important to note that if you are growing basil indoors, you may need to supplement sunlight with artificial grow lights to ensure the plants receive the necessary amount of light.
While basil plants thrive in full sun, they can tolerate some light shade during the hottest part of the day. In fact, a little afternoon shade can be beneficial to prevent the plants from getting stressed or overheated. If you live in an extremely hot climate, providing some shade during the peak sunlight hours can help protect the basil plants from wilting or burning.
It’s worth noting that basil plants grown in partial shade may not produce as much flavor or essential oils as those grown in full sun. The aromatic compounds responsible for basil’s distinct scent and taste develop best in full sun conditions, resulting in more flavorful leaves for culinary purposes.
The ideal light conditions for basil plant growth involve providing full sun exposure for at least 6 to 8 hours a day. Whether you’re growing basil outdoors or indoors, it’s crucial to ensure the plants receive sufficient light to thrive. With the right light conditions, your basil plants will flourish and provide you with a bountiful harvest of aromatic leaves to enhance your recipes.
Understanding the Sunlight Requirements of Basil
Basil, a popular herb in many cuisines, is not only flavorful but also relatively easy to grow. However, to ensure its success, it is crucial to provide the right sunlight conditions. In this article, we will delve into the sunlight requirements of basil and how it directly impacts its growth and overall health.
Basil needs an ample amount of sunlight to thrive. Ideally, it requires a minimum of six to eight hours of direct sunlight per day. This means that placing your basil plant in a spot that receives full sun exposure is essential. Without sufficient sunlight, basil plants may become weak, leggy, and prone to diseases.
When it comes to growing basil indoors, it is necessary to place the pot close to a south-facing window where it can receive maximum sunlight. If your home lacks a suitable window with adequate sunlight, you can consider using artificial grow lights. These lights should be placed 6-12 inches above the plant and provide around 14-18 hours of artificial sunlight per day.
Outdoor basil plants thrive in full sun. Ensure that the garden bed or container is situated in an area that receives direct sunlight for most of the day. However, it is important to note that basil can tolerate some shade, especially during the hottest parts of the day. If you live in a region with scorching summers, providing a bit of afternoon shade can prevent the leaves from wilting or scorching.
The intensity of sunlight plays a significant role in basil growth. The more intense the sunlight, the better the plants will grow. As basil plants receive ample sunlight, they will develop strong stems, lush foliage, and a more vibrant flavor. On the other hand, insufficient sunlight can lead to stunted growth, pale leaves, and reduced aromatic compounds.
To ensure optimal sunlight exposure, it is crucial to monitor the plant’s surroundings. Keep an eye on the growth pattern of your basil. If you notice the plants leaning or stretching towards the light source, it is an indication that they are not receiving enough sunlight. In such cases, consider changing their location or providing additional light sources.
Basil needs full sun to thrive. Adequate sunlight is key to promoting healthy growth, strong stems, and flavorful foliage. Whether you are growing basil indoors or outdoors, ensure it receives at least six to eight hours of direct sunlight per day. Monitor the plant’s growth and consider supplemental lighting if necessary. By understanding and meeting the sunlight requirements of your basil plants, you can enjoy a bountiful harvest of this aromatic herb.
Sunlight and Basil: A Perfect Match for Thriving Plants
When it comes to growing basil, providing the right amount of sunlight is crucial for its optimal growth and development. Basil plants thrive when they are exposed to full sun, making it a key factor to consider when planning your herb garden. In this article, we will delve into why basil needs full sun and the benefits it brings to these fragrant and flavorful plants.
What is Full Sun?
Full sun refers to a location that receives at least six hours of direct sunlight per day. This means that the area is exposed to bright, unfiltered sunlight without any obstructions such as trees or buildings casting shade. For basil, full sun conditions offer the ideal amount of light energy needed for photosynthesis, which is essential for the plant’s growth and production of flavorful leaves.
Optimal Light Conditions for Basil Plant Growth
Basil is a sun-loving plant that originates from the Mediterranean region, where it grows naturally in warm and sunny climates. To mimic its natural habitat, it is important to provide your basil plants with ample sunlight. Position them in a spot where they can bask in the sun’s rays for the majority of the day.
The more sunlight basil receives, the better it will grow and produce abundant leaves. Without enough sunlight, basil plants may become weak and leggy, with sparse foliage. Insufficient light can also cause the plants to stretch towards the light source, resulting in a lanky appearance. To avoid these issues, it is crucial to provide your basil plants with full sun exposure.
The Benefits of Full Sun for Basil Plants
Providing full sun to your basil plants offers a range of benefits that contribute to their overall health and productivity. Here are some advantages of ensuring your basil plants receive sufficient sunlight:
- Enhanced Leaf Production: Full sun exposure promotes vigorous leaf growth, allowing your basil plants to produce an abundance of aromatic leaves.
- Improved Flavor: Sunlight plays a crucial role in enhancing the flavor profile of basil leaves. The warmth and intensity of full sun help intensify the essential oils responsible for the herb’s distinctive taste.
- Prevention of Disease: Basil plants exposed to full sun have better air circulation and lower humidity levels, reducing the risk of fungal diseases such as powdery mildew.
- Stronger Plant: Ample sunlight helps strengthen the stems of basil plants, making them more resistant to damage from winds or heavy rains.
For basil plants to thrive and reach their full potential, they require full sun exposure. This ensures optimal leaf production, enhanced flavor, and overall robustness. By incorporating full sun into your basil growing regimen, you will be rewarded with healthy and flavorful harvests, making your herb garden a true delight.
The Importance of Providing Full Sun to Basil Plants
Basil is a popular herb known for its aromatic leaves and versatile culinary uses. For successful growth and abundant harvest, it is crucial to understand the sunlight requirements of basil plants. One of the key factors that contribute to the well-being of basil plants is the amount of sunlight they receive. Full sun is highly beneficial for basil plants and plays a vital role in their overall health and vigor.
When we talk about full sun, we are referring to a minimum of six hours of direct sunlight per day. Basil plants thrive when they receive ample sunshine, as it provides them with the energy required for photosynthesis, the process by which they convert sunlight into food. Full sun exposure ensures that the basil plants receive an adequate amount of light energy, allowing them to generate the nutrients necessary for growth and development.
One of the primary advantages of providing full sun to basil plants is improved leaf production. Basil plants grown in full sun tend to produce larger and more abundant leaves compared to those grown in shady areas or under inadequate light conditions. The leaves of basil are the main source of flavor, so having an abundance of lush and full leaves enhances both the taste and visual appeal of the herb.
Besides promoting leaf production, full sun exposure also strengthens the overall structure of basil plants. Adequate sunlight helps basil plants develop strong stems and branches, enabling them to support the weight of the abundant foliage. This is especially important for bushy basil varieties that can become top-heavy if not properly supported by a sturdy framework developed through proper exposure to sunlight.
In addition to leaf production and structural strength, full sun plays a significant role in enhancing the flavor and aroma of basil leaves. The essential oils responsible for the distinct fragrance and taste of basil are influenced by sunlight. Full sun exposure intensifies the flavor profile of basil leaves, resulting in a more aromatic and flavorful herb that is well-suited for a variety of culinary applications.
However, while full sun is essential for basil plants, it is essential to strike a balance. Extremely high temperatures and excessive sunlight can cause damage to the plants, leading to leaf scorching or wilting. It is crucial to monitor the plants during hot summer months and provide some protection, such as light shading during the hottest part of the day, to prevent sunburn and dehydration.
Providing full sun to basil plants is of utmost importance for their optimal growth and productivity. It ensures increased leaf production, strengthens the plant’s structure, and enhances the flavor and aroma of the leaves. By understanding the sunlight requirements of basil plants and incorporating full sun exposure into their care routine, gardeners can enjoy thriving basil plants that provide a bountiful harvest while adding a delightful touch to their culinary creations.
It is clear that basil plants thrive in full sun conditions. Understanding the sunlight requirements of basil is vital for their optimal growth and productivity. Basil plants need at least six to eight hours of direct sunlight per day, making them a perfect match for areas with ample sunlight. The ideal light conditions for basil plant growth include a balance of sunlight and shade, as prolonged exposure to intense sunlight can lead to stress and damage.
Providing full sun to basil plants is essential due to several reasons. Firstly, sunlight is crucial for photosynthesis, the process by which plants convert light energy into chemical energy to fuel growth. The chlorophyll in basil leaves absorbs sunlight, facilitating the conversion of carbon dioxide and water into sugars and oxygen. Without adequate sunlight, basil plants may struggle to produce the energy needed for growth and development.
Additionally, sunlight plays a significant role in the overall health and vigor of basil plants. Full sun exposure promotes sturdy stem growth, ensuring that the plant can support a robust foliage. Basil plants grown in full sun are less likely to become leggy and weak, resulting in a more compact and attractive appearance.
Sunlight also influences the flavor and aroma of the basil leaves. Basil plants that receive ample sunlight tend to have a stronger and more pronounced flavor profile. The intensity of sunlight helps enhance the essential oils responsible for the characteristic taste and fragrance of basil. Therefore, by providing full sun, you can guarantee the culinary delight that basil is known for.
While basil plants require full sun, it is essential to maintain a balance between intense sunlight and shade. Extreme heat and prolonged exposure to sunlight can cause stress and damage to the plants. In hot regions, providing some afternoon shade or utilizing shade cloth can help protect the basil plants from scorching temperatures. Regular watering and proper soil moisture are also crucial for the overall well-being of basil plants.
Basil plants require full sun for optimal growth, flavor, and overall health. Understanding the sunlight requirements of basil and providing the ideal light conditions are crucial for ensuring the flourishing of these culinary herbs. By giving basil plants the right amount of direct sunlight and maintaining a balance with shade, you can enjoy bountiful harvests of aromatic and tasty basil leaves.

Below is an article I found recently. This one of the most comprehensive descriptions of PIN Verification Value (PVV) hacking.
I thought I would replicate it here for my local reference.
As comments have been made regarding the grammar used in the original text, I have corrected some of the obvious errors whilst maintaining the context of the original material.
——– Original Text ———-
Have you ever wonder what would happen if you lose your credit or debit card and someone finds it. Would this person be able to withdraw cash from an ATM guessing, somehow, your PIN? Moreover, if you were who finds someone’s card would you try to guess the PIN and take the chance to get some easy money? Of course the answer to both questions should be “no”. This work does not deal with the second question, it is a matter of personal ethics. Herewith I try to answer the first question.
All the information used for this work is public and can be freely found in Internet. The rest is a matter of mathematics and programming, thus we can learn something and have some fun. I reveal no secrets. Furthermore, the aim (and final conclusion) of this work is to demonstrate that PIN algorithms are still strong enough to provide sufficient security. We all know technology is not the weak point.
This work analyses one of the most common PIN algorithms, VISA PVV, used by many ATM cards (credit and debit cards) and tries to find out how resistant is to PIN guessing attacks. By “guessing” I do not mean choosing a random PIN and trying it in an ATM. It is well known that generally we are given three consecutive trials to enter the right PIN, if we fail ATM keeps the card. As VISA PIN is four digit long it’s easy to deduce that the chance for a random PIN guessing is 3/10000 = 0.0003, it seems low enough to be safe; it means you need to lose your card more than three thousand times (or losing more than three thousand cards at the same time 🙂 until there is a reasonable chance of losing money.
What I really meant by “guessing” was breaking the PIN algorithm so that given any card you can immediately know the associated PIN. Therefore this document studies that possibility, analyzing the algorithm and proposing a method for the attack. Finally we give a tool which implements the attack and present results about the estimated chance to break the system. Note that as long as other banking security related algorithms (other PIN formats such as IBM PIN or card validation signatures such as CVV or CVC) are similar to VISA PIN, the same analysis can be done yielding nearly the same results and conclusions.
VISA PVV algorithm
One of the most common PIN algorithms is the VISA PIN Verification Value (PVV). The customer is given a PIN and a magnetic stripe card. Encoded in the magnetic stripe is a four digit number, called PVV. This number is a cryptographic signature of the PIN and other data related to the card. When a user enters his/her PIN the ATM reads the magnetic stripe, encrypts and sends all this information to a central computer. There a trial PVV is computed using the customer entered PIN and the card information with a cryptographic algorithm. The trial PVV is compared with the PVV stored in the card, if they match the central computer returns to the ATM authorization for the transaction. See in more detail.
The description of the PVV algorithm can be found in two documents linked in the previous page. In summary it consists in the encryption of a 8 byte (64 bit) string of data, called Transformed Security Parameter (TSP), with DES algorithm (DEA) in Electronic Code Book mode (ECB) using a secret 64 bit key. The PVV is derived from the output of the encryption process, which is a 8 byte string. The four digits of the PVV (from left to right) correspond to the first four decimal digits (from left to right) of the output from DES when considered as a 16 hexadecimal character (16 x 4 bit = 64 bit) string. If there are no four decimal digits among the 16 hexadecimal characters then the PVV is completed taken (from left to right) non decimal characters and decimalizing them by using the conversion A->0, B->1, C->2, D->3, E->4, F->5. Here is an example:
Output from DES: 0FAB9CDEFFE7DCBA
The strategy of avoiding decimalization by skipping characters until four decimal digits are found (which happens to be nearly all the times as we will see below) is very clever because it avoids an important bias in the distribution of digits which has been proven to be fatal for other systems, although the impact on this system would be much lower. See also a related problem not applying to VISA PVV.
The TSP, seen as a 16 hexadecimal character (64 bit) string, is formed (from left to right) with the 11 rightmost digits of the PAN (card number) excluding the last digit (check digit), one digit from 1 to 6 which selects the secret encrypting key and finally the four digits of the PIN. Here is an example:
PAN: 1234 5678 9012 3445
Key selector: 1
Obviously the problem of breaking VISA PIN consists in finding the secret encrypting key for DES. The method for that is to do a brute force search of the key space. Note that this is not the only method, one could try to find a weakness in DEA, many tried, but this old standard is still in wide use (now been replaced by AES and RSA, though). This demonstrates it is robust enough so that brute force is the only viable method (there are some better attacks but not practical in our case, for a summary see LASEC memo and for the dirty details see Biham & Shamir 1990, Biham & Shamir 1991, Matsui 1993, Biham & Biryukov 1994 and Heys 2001).
The key selector digit was very likely introduced to cover the possibility of a key compromise. In that case they just have to issue new cards using another key selector. Older cards can be substituted with new ones or simply the ATM can transparently write a new PVV (corresponding to the new key and keeping the same PIN) next time the customer uses his/her card. For the shake of security all users should be asked to change their PINs, however it would be embarrassing for the bank to explain the reason, so very likely they would not make such request.
Preparing the attack
A brute force attack consists in encrypting a TSP with known PVV using all possible encrypting keys and compare each obtained PVV with the known PVV. When a match is found we have a candidate key. But how many keys we have to try? As we said above the key is 64 bit long, this would mean we have to try 2^64 keys. However this is not true. Actually only 56 bits are effective in DES keys because one bit (the least significant) out of each octet was historically reserved as a checksum for the others; in practice those 8 bits (one for each of the 8 octets) are ignored.
Therefore the DES key space consists of 2^56 keys. If we try all these keys will we find one and only one match, corresponding to the bank secret key? Certainly not. We will obtain many matching keys. This is because the PVV is only a small part (one fourth) of the DES output. Furthermore the PVV is degenerated because some of the digits (those between 0 and 5 after the last, seen from left to right, digit between 6 and 9) may come from a decimal digit or from a decimalized hexadecimal digit of the DES output. Thus many keys will produce a DES output which yields to the same matching PVV.
Then what can we do to find the real key among those other false positive keys? Simply we have to encrypt a second different TSP, also with known PVV, but using only the candidate keys which gave a positive matching with the first TSP-PVV pair. However there is no guarantee we won’t get again many false positives along with the true key. If so, we will need a third TSP-PVV pair, repeat the process and so on.
Before we start our attack we have to know how many TSP-PVV pairs we will need. For that we have to calculate the probability for a random DES output to yield a matching PVV just by chance. There are several ways to calculate this number and here I will use a simple approach easy to understand but which requires some background in mathematics of probability.
A probability can always be seen as the ratio of favorable cases to possible cases. In our problem the number of possible cases is given by the permutation of 16 elements (the 0 to F hexadecimal digits) in a group of 16 of them (the 16 hexadecimal digits of the DES output). This is given by 16^16 ~ 1.8 * 10^19 which of course coincides with 2^64 (different numbers of 64 bits). This set of numbers can be separated into five categories:
Those with at least four decimal digits (0 to 9) among the 16 hexadecimal digits (0 to F) of the DES output.
Those with exactly only three decimal digits.
Those with exactly only two decimal digits.
Those with exactly only one decimal digit.
Those with no decimal digits (all between A and F).
Let’s calculate how many numbers fall in each category. If we label the 16 hexadecimal digits of the DES output as X1 to X16 then we can label the first four decimal digits of any given number of the first category as Xi, Xj, Xk and Xl. The number of different combinations with this profile is given by the product 6 i-1 * 10 * 6j-i-1 * 10 * 6k-j-1 * 10 * 6 l-k-1 * 10 * 1616-l where the 6’s come from the number of possibilities for an A to F digit, the 10’s come from the possibilities for a 0 to 9 digit, and the 16 comes from the possibilities for a 0 to F digit. Now the total numbers in the first category is simply given by the summation of this product over i, j, k, l from 1 to 16 but with i < j < k < l. If you do some math work you will see this equals to the product of 104/6 with the summation over i from 4 to 16 of (i-1) * (i-2) * (i-3) * 6i-4 * 16 16-i ~ 1.8 * 1019.
Analogously the number of cases in the second category is given by the summation over i, j, k from 1 to 16 with i < j < k of the product 6i-1 * 10 * 6j-i-1 * 10 * 6k-j-1 * 10 * 616-k which you can work it out to be 16!/(3! * (16-13)!) * 103 * 6 13 = 16 * 15 * 14/(3 * 2) * 103 * 613 = 56 * 104 * 613 ~ 7.3 * 1015. Similarly for the third category we have the summation over i, j from 1 to 16 with i < j of 6 i-1 * 10 * 6j-i-1 * 10 * 616-j which equals to 16!/(2! * (16-14)!) * 102 * 614 = 2 * 103 * 615 ~ 9.4 * 1014. Again, for the fourth category we have the summation over i from 1 to 16 of 6i-1 * 10 * 616-i = 160 * 615 ~ 7.5 * 1013. And finally the amount of cases in the fifth category is given by the permutation of six elements (A to F digits) in a group of 16, that is, 616 ~ 2.8 * 1012.
I hope you followed the calculations up to this point, the hard part is done. Now as a proof that everything is right you can sum the number of cases in the 5 categories and see it equals the total number of possible cases we calculated before. Do the operations using 64 bit numbers or rounding (for floats) or overflow (for integers) errors won’t let you get the exact result.
Up to now we have calculated the number of possible cases in each of the five categories, but we are interested in obtaining the number of favorable cases instead. It is very easy to derive the latter from the former as this is just fixing the combination of the four decimal digits (or the required hexadecimal digits if there are no four decimal digits) of the PVV instead of letting them free. In practice this means turning the 10’s in the formula above into 1’s and the required amount of 6’s into 1’s if there are no four decimal digits. That is, we have to divide the first result by 104, the second one by 103 * 6, the third one by 102 * 62 , the fourth one by 10 * 63 and the fifth one by 64 . Then the number of favorable cases in the five categories are approximately 1.8 * 1015, 1.2 * 1012, 2.6 * 1011 , 3.5 * 1010, 2.2 * 109 respectively.
Now we are able to obtain what is the probability for a DES output to match a PVV by chance. We just have to add the five numbers of favorable cases and divide it by the total number of possible cases. Doing this we obtain that the probability is very approximately 0.0001 or one out of ten thousand. Is it strange this well rounded result? Not at all, just have a look at the numbers we calculated above. The first category dominates by several orders of magnitude the number of favorable and possible cases. This is rather intuitive as it seems clear that it is very unlikely not having four decimal digits (10 chances out of 16 per digit) among 16 hexadecimal digits. We saw previously that the relationship between the number of possible and favorable cases in the first category was a division by 10^4, that’s where our result p = 0.0001 comes from.
Our aim for all these calculations was to find out how many TSP-PVV pairs we need to carry a successful brute force attack. Now we are able to calculate the expected number of false positives in a first search: it will be the number of trials times the probability for a single random false positive, i.e. t * p where t = 2^56, the size of the key space. This amounts to approximately 7.2 * 10^12, a rather big number. The expected number of false positives in the second search (restricted to the positive keys found in the first search) will be (t * p) * p, for a third search will be ((t * p) * p) * p and so on. Thus for n searches the expected number of false positives will be t * p^n.
We can obtain the number of searches required to expect just one false positive by expressing the equation t * p^n = 1 and solving for n. So n equals to the logarithm in base p of 1/t, which by properties of logarithms it yields n = log(1/t)/log(p) ~ 4.2. Since we cannot do a fractional search it is convenient to round up this number. Therefore what is the expected number of false positives if we perform five searches? It is t * p^5 ~ 0.0007 or approximately 1 out of 1400. Thus using five TSP-PVV pairs is safe to obtain the true secret key with no false positives.
Once we know we need five TSP-PVV pairs, how do we get them? Of course we need at least one card with known PIN, and due to the nature of the PVV algorithm, that’s the only thing we need. With other PIN systems, such as IBM, we would need five cards, however this is not necessary with VISA PVV algorithm. We just have to read the magnetic stripe and then change the PIN four times but reading the card after each change.
It is necessary to read the magnetic stripe of the card to get the PVV and the encrypting key selector. You can buy a commercial magnetic stripe reader or make one yourself following the instructions you can find in the previous page and links therein. Once you have a reader see this description of standard magnetic tracks to find out how to get the PVV from the data read. In that document the PVV field in tracks 1 and 2 is said to be five character long, but actually the true PVV consists of the last four digits. The first of the five digits is the key selector. I have only seen cards with a value of 1 in this digit, which is consistent with the standard and with the secret key never being compromised (and therefore they did not need to move to another key changing the selector).
I did a simple C program, getpvvkey.c, to perform the attack. It consists of a loop to try all possible keys to encrypt the first TSP, if the derived PVV matches the true PVV a new TSP is tried, and so on until there is a mismatch, in which case the key is discarded and a new one is tried, or the five derived PVVs match the corresponding true PVVs, in which case we can assume we got the bank secret key, however the loop goes on until it exhausts the key space. This is done to assure we find the true key because there is a chance (although very low) the first key found is a false positive.
It is expected the program would take a very long time to finish and to minimize the risks of a power cut, computer hang out, etc. it does checkpoints into the file getpvvkey.dat from time to time (the exact time depends on the speed of the computer, it’s around one hour for the fastest computers now in use). For the same reason if a positive key is found it is written on the file getpvvkey.key. The program only displays one message at the beginning, the starting position taken from the checkpoint file if any, after that nothing more is displayed.
The DES algorithm is a key point in the program, it is therefore very important to optimize its speed. I tested several implementations: libdes, SSLeay, openssl, cryptlib, nss, libgcrypt, catacomb, libtomcrypt, cryptopp, ufc-crypt. The DES functions of the first four are based on the same code by Eric Young and is the one which performed best (includes optimized C and x86 assembler code). Thus I chose libdes which was the original implementation and condensed all relevant code in the files encrypt.c (C version) and x86encrypt.s (x86 assembler version). The code is slightly modified to achieve some enhancements in a brute force attack: the initial permutation is a fixed common steep in each TSP encryption and therefore can be made just one time at the beginning. Another improvement is that I wrote a completely new setkey function (I called it nextkey) which is optimum for a brute force loop.
To get the program working you just have to type in the corresponding place five TSPs and their PVVs and then compile it. I have tested it only in UNIX platforms, using the makefile Makegetpvvkey to compile (use the command “make -f Makegetpvvkey”). It may compile on other systems but you may need to fix some things. Be sure that the definition of the type long64 corresponds to a 64 bit integer. In principle there is no dependence on the endianness of the processor. I have successfully compiled and run it on Pentium-Linux, Alpha-Tru64, Mips-Irix and Sparc-Solaris. If you do not have and do not want to install Linux (you don’t know what you are missing 😉 you still have the choice to run Linux on CD and use my program, see my page running Linux without installing it.
Once you have found the secret bank key if you want to find the PIN of an arbitrary card you just have to write a similar program (sorry I have not written it, I’m too lazy 🙂 that would try all 10^4 PINs by generating the corresponding TSP, encrypting it with the (no longer) secret key, deriving the PVV and comparing it with the PVV in the magnetic stripe of the card. You will get one match for the true PIN. Only one match? Remember what we saw above, we have a chance of 0.0001 that a random encryption matches the PVV. We are trying 10000 PINs (and therefore TSPs) thus we expect 10000 * 0.0001 = 1 false positive on average.
This is a very interesting result, it means that, on average, each card has two valid PINs: the customer PIN and the expected false positive. I call it “false” but note that as long as it generates the true PVV it is a PIN as valid as the customer’s one. Furthermore, there is no way to know which is which, even for the ATM; only customer knows. Even if the false positive were not valid as PIN, you still have three trials at the ATM anyway, enough on average. Therefore the probability we calculated at the beginning of this document about random guessing of the PIN has to be corrected. Actually it is twice that value, i.e., it is 0.0006 or one out of more than 1600, still safely low.
It is important to optimize the compilation of the program and to run it in the fastest possible processor due to the long expected run time. I found that the compiler optimization flag -O gets the better performance, thought some improvement is achieved adding the -fomit-frame-pointer flag on Pentium-Linux, the -spike flag on Alpha-Tru64, the -IPA flag on Mips-Irix and the -fast flag on Sparc-Solaris. Special flags (-DDES_PTR -DDES_RISC1 -DDES_RISC2 -DDES_UNROLL -DASM) for the DES code have generally benefits as well. All these flags have already been tested and I chose the best combination for each processor (see makefile) but you can try to fine tune other flags.
According to my tests the best performance is achieved with the AMD Athlon 1600 MHz processor, exceeding 3.4 million keys per second. Interestingly it gets better results than Intel Pentium IV 1800 MHz and 2000 MHz (see figures below, click on them to enlarge). I believe this is due to some I/O saturation, surely cache or memory access, that the AMD processor (which has half the cache of the Pentium) or the motherboard in which it is running, manages to avoid. In the first figure below you can see that the DES breaking speed of all processors has more or less a linear relationship with the processor speed, except for the two Intel Pentium I mentioned before. This is logical, it means that for a double processor speed you’ll get double breaking speed, but watch out for saturation effects, in this case it is better the AMD Athlon 1600 MHz, which will be even cheaper than the Intel Pentium 1800 MHz or 2000 MHz.
In the second figure we can see in more detail what we would call intrinsic DES break power of the processor. I get this value simply dividing the break speed by the processor speed, that is, we get the number of DES keys tried per second and per MHz. This is a measure of the performance of the processor type independently of its speed. The results show that the best processor for this task is the AMD Athlon, then comes the Alpha and very close after it is the Intel Pentium (except for the higher speed ones which perform very poor due to the saturation effect). Next is the Mips processor and in the last place is the Sparc. Some Alpha and Mips processors are located at bottom of scale because they are early releases not including enhancements of late versions. Note that I included the performance of x86 processors for C and assembler code as there is a big difference. It seems that gcc is not a good generator of optimized machine code, but of course we don’t know whether a manual optimization of assembler code for the other processors (Alpha, Mips, Sparc) would boost their results compared to the native C compilers (I did not use gcc for these other platforms) as it happens with the x86 processor.

This article is about the Bluetooth wireless specification. For King Harold Bluetooth, see Harold I of Denmark
Bluetooth is an industrial specification for wireless personal area networks (PANs).
Bluetooth provides a way to connect and exchange information between devices like personal digital assistants (PDAs), mobile phones, laptops, PCs, printers and digital cameras via a secure, low-cost, globally available short range radio frequency.
The spec was first developed by Ericsson, later formalised by the Bluetooth Special Interest Group (SIG). The SIG was formally announced on May 20, 1999. It was established by Sony Ericsson, IBM, Intel, Toshiba and Nokia, and later joined by many other companies as Associate or Adopter members.

About the name
The system is named after a Danish king Harald Blåtand (<arold Bluetooth in English), King of Denmark and Norway from 935 and 936 respectively, to 940 known for his unification of previously warring tribes from Denmark, Norway and Sweden. Bluetooth likewise was intended to unify different technologies like computers and mobile phones. The Bluetooth logo merges the Nordic runes for H and B.
The latest version currently available to consumers is 2.0, but few manufacturers have started shipping any products yet. Apple Computer, Inc. offered the first products supporting version 2.0 to end customers in January 2005. The core chips have been available to OEMs (from November 2004), so there will be an influx of 2.0 devices in mid-2005. The previous version, on which all earlier commercial devices are based, is called 1.2.
Cell phones with integrated Bluetooth technology have also been sold in large numbers, and are able to connect to computers, PDAs and, specifically, to handsfree devices. BMW was the first motor vehicle manufacturer to install handsfree Bluetooth technology in its cars, adding it as an option on its 3 Series, 5 Series and X5 vehicles. Since then, other manufacturers have followed suit, with many vehicles, including the 2004 Toyota Prius and the 2004 Lexus LS 430. The Bluetooth car kits allow users with Bluetooth-equipped cell phones to make use of some of the phone’s features, such as making calls, while the phone itself can be left in a suitcase or in the boot/trunk, for instance.
The standard also includes support for more powerful, longer-range devices suitable for constructing wireless LANs.
A Bluetooth device playing the role of “master” can communicate with up to 7 devices playing the role of “slave”. At any given instant in time, data can be transferred between the master and one slave; but the master switches rapidly from slave to slave in a round-robin fashion. (Simultaneous transmission from the master to multiple slaves is possible, but not used much in practice). These groups of up to 8 devices (1 master and 7 slaves) are called piconets.
The Bluetooth specification also allows connecting two or more piconets together to form a scatternet, with some devices acting as a bridge by simultaneously playing the master role in one piconet and the slave role in another piconet. These devices have yet to come, though are supposed to appear within the next two years.
Any device may perform an “inquiry” to find other devices to which to connect, and any device can be configured to respond to such inquiries.
Pairs of devices may establish a trusted relationship by learning (by user input) a shared secret known as a “passkey”. A device that wants to communicate only with a trusted device can cryptographically authenticate the identity of the other device. Trusted devices may also encrypt the data that they exchange over the air so that no one can listen in.
The protocol operates in the license-free ISM band at 2.45 GHz. In order to avoid interfering with other protocols which use the 2.45 GHz band, the Bluetooth protocol divides the band into 79 channels (each 1 MHz wide) and changes channels up to 1600 times per second. Implementations with versions 1.1 and 1.2 reach speeds of 723.1 kbit/s. Version 2.0 implementations feature Bluetooth Enhanced Data Rate (EDR), and thus reach 2.1 Mbit/s. Technically version 2.0 devices have a higher power consumption, but the three times faster rate reduces the transmission times, effectively reducing consumption to half that of 1.x devices (assuming equal traffic load).
Bluetooth differs from Wi-Fi in that the latter provides higher throughput and covers greater distances but requires more expensive hardware and higher power consumption. They use the same frequency range, but employ different multiplexing schemes. While Bluetooth is a cable replacement for a variety of applications, Wi-Fi is a cable replacement only for local area network access. A glib summary is that Bluetooth is wireless USB whereas Wi-Fi is wireless Ethernet.
Bluetooth devices and modules are increasingly being made available which come with an embedded stack and a standard UART port. The UART protocol can be as simple as the industry standard AT protocol, which allows the device to be configured to cable replacement mode. This means it now only takes a matter of hours (instead of weeks) to enable legacy wireless products that communicate via UART port.
Features by version
Bluetooth 1.0 and 1.0B
Versions 1.0 and 1.0B had numerous problems and the various manufacturers had great difficulties in making their products interoperable. 1.0 and 1.0B also had mandatory Bluetooth Hardware Device Address (BD_ADDR) transmission in the handshaking process, rendering anonymity impossible at a protocol level, which was a major set-back for services planned to be used in Bluetooth environments, such as Consumerism.
In version 1.1 many errata found in the 1.0B specifications were fixed. There was added support for non-encrypted channels.
This version is backwards compatible with 1.1 and the major enhancements include
- Adaptive Frequency Hopping (AFH), which improves resistance to radio interference by avoiding using crowded frequencies in the hopping sequence
- Higher transmission speeds in practice
- extended Synchronous Connections (eSCO), which improves voice quality of audio links by allowing retransmissions of corrupted packets.
- Received Signal Strength Indicator (RSSI)
- Host Controller Interface (HCI) support for 3-wire UART
- HCI access to timing information for Bluetooth applications.
This version is backwards compatible with 1.x and the major enhancements include
- Non-hopping narrowband channel(s) introduced. These are faster but have been criticised as defeating a built-in security mechanism of earlier versions; however frequency hopping is hardly a reliable security mechanism by today’s standards. Rather, Bluetooth security is based mostly on cryptography.
- Broadcast/multicast support. Non-hopping channels are used for advertising Bluetooth service profiles offered by various devices to high volumes of Bluetooth devices simultaneously, since there is no need to perform handshaking with every device. (In previous versions the handshaking process takes a bit over one second.)
- Enhanced Data Rate (EDR) of 2.1 Mbit/s.
- Built-in quality of service.
- Distributed media-access control protocols.
- Faster response times.
- Halved power consumption due to shorter duty cycles.
Future Bluetooth uses
One of the ways Bluetooth technology may become useful is in Voice over IP. When VOIP becomes more widespread, companies may find it unnecessary to employ telephones physically similar to today’s analogue telephone hardware. Bluetooth may then end up being used for communication between a cordless phone and a computer listening for VOIP and with an infrared PCI card acting as a base for the cordless phone. The cordless phone would then just require a cradle for charging. Bluetooth would naturally be used here to allow the cordless phone to remain operational for a reasonably long period.
In November 2003, Ben and Adam Laurie from A.L. Digital Ltd. discovered that serious flaws in Bluetooth security lead to disclosure of personal data (see http://bluestumbler.org). It should be noted however that the reported security problems concerned some poor implementations of Bluetooth, rather than the protocol itself.
In a subsequent experiment, Martin Herfurt from the trifinite.group was able to do a field-trial at the CeBIT fairgrounds showing the importance of the problem to the world. A new attack called BlueBug was used for this experiment.
This is one of a number of concerns that have been raised over the security of Bluetooth communications. In 2004 the first purported virus using Bluetooth to spread itself among mobile phones appeared for the Symbian OS. The virus was first described by Kaspersky Labs and requires users to confirm the installation of unknown software before it can propagate. The virus was written as a proof-of-concept by a group of virus writers known as 29a and sent to anti-virus groups. Because of this, it should not be regarded as a security failure of either Bluetooth or the Symbian OS. It has not propagated ‘in the wild’.
In August 2004, a world-record-setting experiment (see also Bluetooth sniping) showed that with directional antennas the range of class 2 Bluetooth radios could be extended to one mile. This enables attackers to access vulnerable Bluetooth-devices from a distance beyond expectation.
In order to use Bluetooth, a device must be able to interpret certain Bluetooth profiles. These define the possible applications. Following profiles are defined:
- Generic Access Profile (GAP)
- Service Discovery Application Profile (SDAP)
- Cordless Telephony Profile (CTP)
- Intercom Profile (IP)
- Serial Port Profile (SPP)
- Headset Profile (HSP)
- Dial-up Networking Profile (DUNP)
- Fax Profile
- LAN Access Profile (LAP)
- Generic Object Exchange Profile (GOEP)
- Object Push Profile (OPP)
- File Transfer Profile (FTP)
- Synchronisation Profile (SP)
This profile allows synchronisation of Personal Information Manager (PIM) items. As this profile originated as part of the infra-red specifications but has been adopted by the Bluetooth SIG to form part of the main Bluetooth specification, it is also commonly referred to as IrMC Synchronisation.
- Hands-Free Profile (HFP)
- Human Interface Device Profile (HID)
- Hard Copy Replacement Profile (HCRP)
- Basic Imaging Profile (BIP)
- Personal Area Networking Profile (PAN)
- Basic Printing Profile (BPP)
- Advanced Audio Distribution Profile (A2DP)
- Audio Video Remote Control Profile (AVRCP)
- SIM Access Profile (SAP)
Compatibility of products with profiles can be verified on the Bluetooth Qualification website.

Graves’ disease is an autoimmune thyroid disorder that results in the overproduction of thyroid hormones. This can lead to several symptoms, including anxiety, weight loss, and fatigue. Graves’ disease is the most common cause of hyperthyroidism during pregnancy, and it can pose a serious threat to both mother and child.
Left untreated, Graves’ disease can lead to preterm labor, placental abruption, and stillbirth. Management of hyperthyroidism in pregnancy requires an appreciation of normal thyroid hormone physiology during gestation, the role of anti thyroid medications in management, and mitigating strategies to prevent fetal harm. Treatment of Graves disease during pregnancy is essential to ensure a healthy outcome for both mother and child.
Normal thyroid hormone physiology in pregnancy
Human chorionic Gonadotropin (hCG) is structurally similar to thyroid-stimulating hormone (thyrotropin) at the alpha subunit. Therefore placental hCG can stimulate the thyroid gland of a pregnant woman leading to productive hyperthyroidism.
Consequently, excess thyroid hormone leads to negative feedback inhibition of endogenous thyrotropin production. For this reason, pregnant women typically have a median TSH level that is comparatively lower than that of their nonpregnant counterparts. This is even more pronounced in the first trimester says, which is when hCG levels tend to peak during pregnancy.
It is essential to note that maternal thyrotropin-releasing hormone plays a critical role in the growth and development of the fetus. Indeed, thyrotropin-releasing hormone and thyroxine (T4) cross the placenta to the fetus during intrauterine life.
Thyroxine (T4) assists in the neurological development of the fetus in the first trimester, up until the fetus’s hypothalamo-pituitary-thyroid axis develops by 12 weeks of gestation.
Deiodinase type III (D3) enzyme is typically expressed by the placenta and regulates the availability of thyroxine to the developing baby. Consequently, in the setting of maternal hyperthyroidism, this enzyme will prevent overexposure of the fetus to high levels of thyroid hormone, by converting both T3 and T4 into their inactive metabolites.. This makes D3 the most potent physiologic inactivator of thyroid hormone.
Also, iodine, critical for the formation of thyroid hormone, crosses the placenta freely since there is a ubiquitous expression of sodium iodide symporters (NIS) by syncytiotrophoblasts. TSH receptor antibodies (thyroid-stimulating immunoglobulin and thyrotropin binding inhibitory immunoglobulin) typically cross the placenta and may negatively impact fetal thyroid function.
Symptoms of Graves Disease during pregnancy
Graves disease can lead to a number of symptoms, including weight loss, anxiety, tremors, and increased heart rate. Graves’ disease can also affect the eyes, causing bulging and inflammation. In pregnant women, Graves’ disease can lead to premature birth, low birth weight, and miscarriages.
Physical Exam for Graves disease in pregnancy
In Graves disease, physical exam findings may include goiter, tachycardia, tremulousness of the extremities, and ophthalmopathy. During pregnancy, these findings may be more pronounced. Additionally, pregnant women with Graves disease may have an increased risk for preeclampsia (high blood pressure) and other complications.
Preconception planning for Graves’ disease
A woman with Graves’ disease should be clinically and biochemically euthyroid before proceeding with pregnancy. Pregnant women who are thyrotoxic on anti thyroid drugs or euthyroid on relatively high doses of antithyroid drugs should be considered for some form of definitive therapy before considering pregnancy.
Depending on the definitive therapy chosen, the “time-to-pregnancy” can vary significantly. For example, for women who choose to have radioactive iodine ablation, contraception is required for a minimum of six months to prevent exposure of the fetus to the effects of radiation.
Women who opt for total thyroidectomy may proceed with pregnancy after normalizing their thyroid status.
The clinical course of Graves’ disease in pregnancy
As was previously mentioned, expectant mothers may normally develop mild hyperthyroidism during pregnancy. This is more likely in the first trimester due to beta hCG levels reaching their peak during this phase of pregnancy.
This effect accounts for both transient hCG-mediated hyperthyroidism and hyperemesis gravidarum of pregnancy. Both conditions are self-limiting and resolve by 14 to 18 weeks of gestation with minimal complications.
In addition, women with Graves’ disease may experience a significant exacerbation of hyperthyroid symptoms during the first trimester (peak effect of hCG), although there is an expected improvement during the second and third trimesters.
The table below summarizes the clinical course of Graves’ disease during pregnancy.
Stage of pregnancy | Clinical course | Mechanism |
First Trimester | Aggravation of graves hyperthyroidism | HCG-mediated thyroid hormone production |
Second and third trimester | Significant improvement in hyperthyroidism | An increase in thyroxine-binding globulin (data were estrogen production) leads to a reduction in free thyroid hormone. Suppression of thyroid autoimmunity by estradiol, progesterone, and cortisol. |
Postdelivery | Worsening thyroid function | Reactivation of thyroid autoimmunity in the absence of placental steroids |
Management of Graves’ disease in pregnancy
The goal of management is to prevent exposure of the fetus to an excessively high amount of maternally derived thyroid hormone while maintaining near-optimal thyroid hormone levels in the expectant mother.
For this reason, women with Graves’ disease should be borderline hyperthyroid in order to reduce the risk of fetal harm. Indeed, antithyroid medications should not be initiated if the patient has subclinical, asymptomatic, or mild overt hyperthyroidism.
Patients should generally have their thyroid function test evaluated every 4 to 6 weeks. For patients requiring treatment (moderate to severe overt hyperthyroidism), propylthiouracil is recommended in the first trimester due to the risk of choanal atresia (birth defects) associated with methimazole.
During the second and third trimesters, patients should be switched from propylthiouracil to methimazole due to the high risk of liver injury associated with the former.
Beta-blockers (atenolol) help control adrenergic symptoms, although they should be discontinued after an improvement in free thyroid hormone levels. While beta-blockers are generally considered safe, there is some concern that they may be associated with adverse effects in pregnant women. In particular, beta-blockers have been linked to an increased risk of miscarriage and intrauterine growth restriction.
Thyrotropin receptor antibodies (TRAB) should be measured in the third trimester in all patients with Graves’ disease. With TRAB titers at least three times the upper limit of normal, being highly predictive of neonatal hyperthyroidism. This test is important because TRABs can cross the placenta (during separation) and stimulate the thyroid of the neonate after delivery.
Safety of breastfeeding while on anti-thyroid medications
Mothers with Graves disease who are taking methimazole or propylthiouracil (PTU) can breastfeed if they have their infant’s thyroid function checked and maintain their own thyroid function within the normal range.
Traditionally, anti-thyroid drugs have been discouraged for breastfeeding mothers. Although both propylthiouracil and methimazole can be detected in milk, the concentrations are quite minimal, leaving little to no fetal harm.
Indeed, studies have shown that the milk to plasma ratio of propylthiouracil is 0.1, with less than 3% of the weight-adjusted dose of propylthiouracil being present in the feeding. For mothers on methimazole, the maximum amount of weight-adjusted methimazole present in breast milk is about 12%. Indeed, it has been shown that in patients treated with 20 mg of methimazole per day, no demonstrable clinical harm occurs in the infant.
Because both methimazole and PTU can cross into breast milk, mother and infant should be monitored closely for signs and symptoms of hypothyroidism or hyperthyroidism. If either condition develops, the infant should be evaluated by a pediatrician and the mother’s dose of methimazole or PTU should be adjusted accordingly.
Pregnant women with a remote history of Graves’ disease that has been successfully treated with either total thyroidectomy or radioactive iodine ablation should have their thyrotropin receptor antibodies checked to predict the risk for neonatal thyrotoxicosis.
Treatment of Graves’ disease with either surgery or radioactive iodine does not lead to an amelioration of thyroid-related autoimmunity. Indeed, these patients may still have high levels of circulating thyroid-stimulating immunoglobulins, which can not lead to hyperthyroidism in the mother but can still cross the placenta and lead to neonatal thyrotoxicosis.

When considering how to enhance the mental and physical stimulation of your turtle, it is essential to keep their unique species-specific needs in mind. By providing a diverse and enriching environment, you can ensure their overall well-being.
Improved eating and foraging behavior
In order to promote improved eating and foraging behavior in turtles, it is crucial to create an environment that enhances their natural instincts. Turtles heavily rely on their ability to find and consume food in their natural habitats for their overall health and well-being. By offering a diverse range of food options, we can stimulate their natural foraging instincts and encourage them to explore and consume different types of food.
To further enhance their eating and foraging behavior, interactive feeding methods can be incorporated. This can involve hiding food in their enclosure or using puzzle feeders that require problem-solving skills to access the food. By actively searching for and retrieving their food, turtles can engage in their natural behaviors.
Creating a naturalistic environment is also essential. By adding plants, rocks, and logs to their enclosure, we can mimic the natural habitat of turtles. This will encourage them to engage in natural foraging behaviors such as digging and searching for food.
In addition, providing appropriate feeding tools that simulate the texture and shape of natural prey items can further promote improved eating and foraging behavior. Using tongs or tweezers to simulate the movement of live prey or feeding sticks to encourage reaching for food can be effective methods.
By implementing these strategies, we can help turtles develop and maintain healthy eating and foraging habits. Not only will this support their physical health, but it will also contribute to their overall happiness and well-being.
Considerations for Keeping Turtles Together
Keeping turtles together requires careful consideration to ensure their well-being. In this section, we will explore important factors to keep in mind when it comes to turtle companionship. From species compatibility to enclosure size and setup, as well as gender considerations, we will dive into the key aspects that influence the successful cohabitation of turtles. So, if you’re thinking about introducing new turtle friends to your current setup, read on for valuable insights and practical advice.
When considering keeping multiple turtles together, it is crucial to take into account their species compatibility. Not all turtle species can coexist peacefully, and combining incompatible species can result in aggression and stress. Here are some factors to consider:
- Size: Turtles of similar sizes are more likely to get along. Large turtles may perceive smaller ones as prey or become territorial towards them.
- Behavior: Some turtle species are naturally more aggressive or territorial than others. It is vital to research the behavior of the species you are considering keeping together.
- Diet: Turtles have different dietary requirements, and it may be challenging to keep species with vastly different diets together. Ensuring that all turtles can access their appropriate food is crucial.
- Temperature and Habitat: Different turtle species have specific temperature and habitat requirements. Coexisting species should have similar environmental needs to ensure their well-being and prevent stress.
- Gender: Introducing male and female turtles of the same species can lead to breeding behavior and potential aggression. Understanding the sex ratio of the turtles you are keeping together is vital.
Considering these factors will help ensure species compatibility when keeping multiple turtles together. It is essential to provide a harmonious environment that promotes the well-being and safety of all turtles involved.
Enclosure size and setup
When it comes to setting up an enclosure for your turtle, there are a few important factors to take into consideration. First and foremost is the size of the enclosure. You want to ensure that the enclosure is large enough to accommodate your turtle’s size and give them room to move around. A good guideline to follow is providing at least 10 gallons of water per inch of shell length for aquatic turtles.
Next, you need to think about the materials used for the enclosure. It’s important to choose a sturdy and safe material, such as glass or plastic. You want to avoid using materials that could be harmful if ingested or have sharp edges that could potentially hurt your turtle.
Another important factor is providing both water and land areas in the enclosure. This is crucial to meet your turtle’s natural needs. It’s important to note that aquatic turtles will require a larger water area compared to land-dwelling species.
Don’t forget about heating and lighting! Installing appropriate heat and UVB lighting is essential in creating a suitable environment for your turtle. This helps regulate their body temperature and provides the necessary UV rays for proper shell and bone health.
Incorporating hideouts and enrichment elements is also important. You want to include hiding spots, rocks, logs, and plants in the enclosure to simulate a natural habitat. This not only provides privacy and security for your turtle but also offers opportunities for exploration and physical activity.
Lastly, it’s crucial to regularly clean and maintain the enclosure to ensure the health and well-being of your turtle. Monitor the temperature and water quality, and provide a balanced diet to promote a happy and thriving turtle.
Remember, proper enclosure size and setup are key to providing a suitable and comfortable living environment for your turtle!
When considering keeping turtles together, there are some important gender considerations to take into account:
- If you want to breed turtles, it is crucial to have both male and female turtles in the enclosure. Without both genders, reproduction will not be possible.
- Male turtles can sometimes display aggressive behavior towards each other, especially during mating season. It is important to monitor their interactions closely and provide enough space for each turtle to establish its territory.
- Female turtles may also become aggressive towards males if they are not interested in mating. This can lead to stress and potential injuries, so it is important to be aware of their behavior and provide separate spaces if needed.
- If you only want to keep turtles as pets and not breed them, it is generally recommended to keep turtles of the same gender together to minimize aggression and potential conflicts.
Pro-tip: When introducing new turtles to an existing group, it’s always a good idea to observe their behavior closely and provide enough hiding spots and resources to reduce competition and potential conflicts.
Signs of a Happy and Healthy Turtle
A happy and healthy turtle displays fascinating behaviors that indicate their well-being. From being active and alert to having a healthy appetite, these signs provide valuable insights into their overall health. Let’s dive into the world of turtles and discover what their energetic behavior and voracious appetite can tell us about their happiness and vitality. Get ready for a turtle-tastic exploration!
Active and alert behavior
Active and alert behavior is a key indicator of a happy and healthy turtle.
Turtles that demonstrate active and alert behavior show signs of vitality and engagement with their surroundings.
An active turtle will explore its environment, swim, bask in the sun, and interact with other turtles or objects in its enclosure.
Turtles that exhibit alert behavior are attentive and responsive to stimuli.
They may display curiosity by investigating their surroundings, reacting to sounds, or following movements.
Turtles that display active and alert behavior are more likely to be in good overall health.
Regular observation of your turtle is important to ensure it is exhibiting these behaviors.
If your turtle is not demonstrating active and alert behavior, it may indicate a potential health issue or environmental problem that needs to be addressed.
By providing a suitable habitat with proper lighting, temperature, and enrichment, you can encourage your turtle to be active and alert.
A healthy appetite is crucial for the overall well-being and vitality of turtles. Here are some factors to consider related to maintaining a healthy appetite for turtles:
- Appropriate diet: Providing a well-balanced and varied diet is essential for stimulating a healthy appetite in turtles. This should include a mix of commercial reptile pellets, fresh fruits and vegetables, and occasional protein sources like insects or worms.
- Proper feeding schedule: Turtles should be fed at regular intervals to establish a consistent eating routine. Offering food at the same time every day helps turtles develop a strong appetite.
- Optimal temperature: Maintaining the appropriate temperature in the turtle’s enclosure is vital for digestion and metabolic function. Turtles are ectothermic, meaning their body temperature is regulated by the environment. Providing a warm basking spot and a cooler area allows turtles to thermoregulate and aids in digestion.
- Healthy habitat: Turtles thrive in a clean and well-maintained habitat. Regular cleaning of the enclosure and water ensures a hygienic environment, which promotes a healthy appetite. Unclean living conditions can lead to stress or illness, resulting in decreased appetite.
- Offering variety: Introducing different food items can stimulate a turtle’s interest in eating. Experiment with a range of fruits, vegetables, and proteins to maintain their enthusiasm for mealtime.
- Regular hydration: While turtles obtain water through their food and habitat, providing fresh water for soaking and drinking is crucial. Proper hydration supports digestion and appetite.
- Veterinary check-ups: Regular visits to a reptile veterinarian help identify and address any underlying health issues that may affect appetite. Ensure your turtle receives proper medical care and follow any dietary recommendations provided by the veterinarian.
Remember, a healthy appetite is just one aspect of a turtle’s overall well-being, and it is important to consider all factors necessary for their care and happiness.
What to Do If Your Turtle is Lonely or Unhappy
If your turtle is lonely or unhappy, there are several things you can do to improve its well-being:
- What to Do If Your Turtle is Lonely or Unhappy – Provide a companion: Turtles are social creatures and can benefit from having a turtle companion. Introduce a second turtle of the same species and similar age and size to keep your turtle company.
- What to Do If Your Turtle is Lonely or Unhappy – Create a stimulating environment: Add objects like rocks, logs, or plants to the turtle’s enclosure to provide places to explore and hide. This will help prevent boredom and stimulate natural behaviors.
- What to Do If Your Turtle is Lonely or Unhappy – Offer a varied diet: Ensure your turtle is getting a balanced diet by offering a variety of foods, such as leafy greens, vegetables, and commercial turtle pellets. This will keep your turtle healthy and satisfied.
- What to Do If Your Turtle is Lonely or Unhappy – Provide proper lighting and temperature: Turtles require specific lighting and temperature conditions to thrive. Make sure you have the right UVB lighting and a basking spot for your turtle to regulate its body temperature.
- What to Do If Your Turtle is Lonely or Unhappy – Interact with your turtle: Spend time interacting with your turtle by handling it gently or providing supervised outside time. This will help your turtle feel more comfortable and happy in its environment.
Frequently Asked Questions
Can turtles make friends?
No, turtles are solitary animals and do not have the ability to make friends or develop emotions. They react on instincts, not on feelings, and do not have a brain developed for emotions.
Do turtles get lonely?
No, turtles do not experience loneliness like humans do. They are solitary creatures in the wild and prefer to be alone. They do not depend on the presence of other turtles or friends for companionship.
Can I house multiple turtles together?
While it is possible to keep more than one turtle in the same tank, it is important to consider factors such as size, species, gender, and aggression levels. Turtles can be territorial, especially males, and housing them together can lead to fighting and even death. It is recommended to have turtles of the same size, age, and species to ensure a peaceful habitat.
How do I prevent fighting among turtles?
To reduce the chances of fighting among turtles, provide a large enough habitat for each turtle, use visual barriers, feed turtles daily, provide separate basking areas, ensure good water quality, avoid housing multiple male turtles together, be careful about mixing sizes and ages, and consider different pairings. It is important to monitor their behavior and separate them if fighting occurs to prevent serious injuries.
Do turtles need the company of other turtles?
No, turtles do not need the company of other turtles to be happy. They are solitary animals by nature and do not depend on others for companionship. Introducing a new turtle may result in constant fighting, particularly over resources such as food. Turtles prefer to have their own space without disturbance.
Are turtles good pets for busy individuals?
Turtles are often seen as low-maintenance pets, but it is important to understand that they are not as affectionate as dogs or cats. While turtles may show some affection to their owners through allowing touch and following them around, they do not form attachments or experience human-like emotions. Turtles can adapt to being alone from the beginning and do not require constant interaction or socialization. | <urn:uuid:f2ccb540-7ba4-431e-9f4a-3874ba4ba9ba> | CC-MAIN-2024-51 | https://reptilestartup.com/do-turtle-need-friends/ | 2024-12-06T23:09:16Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066421345.75/warc/CC-MAIN-20241206220301-20241207010301-00000.warc.gz | en | 0.945223 | 4,715 | 3.71875 | 4 |
Technological advancements and the development of the internet have led to the development and improvement of multiple media channels and outlets making the media industry one of the most blossoming industry in the 4th industrial revolution. Schwartz (2018) highlights that developments in recent and emerging technology have affected how people communicate learn and work and continue to provide endless opportunity for technological advancements in the media and entertainment industry. which can be a major area of study for those who are seeking business dissertation help. According to BBC (2021), the media industry can be defined as a varied collection of organizations that share in the production, publication and distribution of media texts and visuals. The industry includes an amalgamation of broadcasting and entertainment media including radio and television broadcasting as well as music and filmed entertainment, Media agencies such as advertising companies, public relations and marketing services as well as publishers such as print and electronic media (Schwartz, 2018). With continued advancements in technology these different types of media are effectively advanced and upgraded to be more efficient and effective in mass and individual communication. In addition, the continued development and advancement of the industry leads to the development of employment and new revenue streams making is a significantly promising industry. This essay aims to evaluate the attractiveness of this industry through evaluating the Macro environment of the media industry across the globe as well as the internal environment to highlight specific advantages and its subsequent potential.
The study undertook the macro environmental study of the media industry through the application of the PESTEL analysis technique.
The media industry is one of the very few industries that are impacted by a nation’s political environment. This is largely due to the fact that the media is the first line of communication and information sharing across the world and that every individual has the right to express themselves in whichever manner they wish. According to the international standards of Media Regulations based on UNESCO.Org (2017) Universal Declaration of Human Rights (1948) proclaimed the right to privacy and the right to freedom of opinion and expression basically giving a free pass to the media industry to cover any and all issues of importance to the society without censorship. The media is considered to be a powerful tool in the management of different aspects of the society including the economy and political stability (Picard, and Lowe, 2016). This makes it a significant and wide industry in almost all countries across the globe and as such attractive to develop a career in.
The media industry is one of the most blossoming industries economically across the globe. While technological development has led to the slowdown of print media leading to significant losses in the publishing industry, it has also led to the development of new forms of media such as e-books, online advertising as well as music and video streaming which are contributing significant amount of revenue to the industry and the economy (Omar, 2013). Technological development has also made it easier to acquire information via a wide range of media channels for instance through informative video, YouTube tutorials as well as teleconferencing which enhance telecommuting (Straubhaar et al., 2013; Silverstone, 2017).
According to Desjardins (2017), the media impacts the economy in three main ways; through democratization of information, through the development of platform economy and the development of new ecosystems for entrepreneurial advancement. With easier and faster information acquisition due to its free nature on social media and other media channel as a result of information democratization, the world is seeing faster and more efficient innovation of products and services which further contribute to enhancing economic development. The media industry, especially social media sites such as YouTube, Instagram, and Facebook provide better and more effective ways of marketing products and services for instance through online Ads subsequently enhancing the growth of the platform economy. Such media sites and platforms further provide a new ecosystems for entrepreneurs to build off of and effectively enhance the economy.
The media industry is not only a key aspect of the social environment; it is the most important factor for enhanced social development. Media provides channels and outlets for communication and socialization among different individuals and must be adherent to the set social cultures and beliefs within a country. According to Fern Fort University (2018), the shared attitudes and beliefs of a population play a significant role in how different media industries and companies operate. These values define the parameters and regulations by which various media is to adhere to while at the same time shape the social environment and how different individuals interact with one another. However according to Silver et al. (2019) there are significant concern with regards to the impact of social media specifically on social norms and the society. A wide range of studies have shown a significant negative impact of social media and internet use. For instance social media can aid the spread of inaccurate news and information which eventually impact inefficient social reactions and actions that are detrimental to the society.
The media industry is heavily reliant on the development of technology. With continued development and advancement of technological devices and processes, different activities and channels within the media industry are significantly impacted leading to variances in the cost and structure of the industry as well as its value chain. Technological advancements such as the development of mobile applications to aid the spread and sharing of information has made the industry more instant and impactful to other elements of the society and economy (Silverstone, 2017; Deb, 2014). For instance through the advancement of social media, the marketing and advertising sectors of the industry have been significantly revolutionized to enhance further reach and increased total revenue. Advertisements in the newspapers and magazines as well as Television and Radio have significantly been overtaken by online advertising and digital billboards as a result of technological advancements. Continued development of technology will as such continue impacting changes and upgrades within the media industry making it more effective and efficient in information sharing and influence.
The media industry is primarily for information dissemination and sharing of knowledge. Different media outlets have not only been adopted by different companies within different industries to enhance the spread of information on environmental conservation, but have themselves taken up strategies of enhancing environmental protection and conservation. According to Nyash (2014), different media platforms and channels, for instance broadcasters, entertainers as well as individuals on social media serve to bring people together and help them understand the common problem in environmental degradation as well as offer multiple solutions that can be adopted by everyone in minimizing and ultimately curbing environmental degradation through enhancing environmental conservation.
Further, the advancement of technology despite significantly impacting the publishing and printing press negatively as a result of reduced demand on physical books and increased demand of e-books and Audio books inadvertently helps minimize environmental degradation through deforestation for paper (Omar, 2013). The advancement of technology is hugely shifting all media activities and outlets to the digital technology and thereby enhancing environmental conservation. Given that huge amounts of data can be stored on very small devices with multitudes of space further enhance the minimization of space usage in library and the waste products in daily newspaper and other printing productions.
According to Fern Fort University (2019) there is significant legal framework and institutions in almost all countries that are charged with controlling the content shared across different media sites as well as the protection of intellectual property rights. Different media firms should as such carefully evaluate how comprehensive their intellectual property rights are protected by the law as well as how far they can go with the freedom of expression before it is restricted by legal frameworks. Other legal aspects that may significantly impact the media industry regardless of the country of operation is the consumer protection and e-commerce laws to regulate marketing activities through media for effective protection of consumers against inaccurate information as well as discrimination and prejudice laws which may be enforced due to any inappropriate communications that aid in denying other individuals their rights or slandering others reputations.
The Macro environment of the media industry indicates not only the significance and importance of the media industry to the economy and society but also provides a deeper understanding of how the industry functions and its potential as an effective area for career development. A further evaluation of the internal environment of the industry will indicate its potential for success and adequate attractiveness as an effective industry to invest in, in the contemporary environment. The internal analysis is conducted via a SWOT analysis of the industry highlighting its strengths and the potential opportunities it has to offer.
The media industry has a wide range of significant strengths that impact its attractiveness and viability as an effective industry for investment. According to Gan (2012) the media industry is one of the most booming industries in the global economy as a result of its rapid and diverse development across the past decades. The media industry offers a wide range of career options including, presenters, producers, editors, entertainers, marketers and social media influencers. While established media companies such as TV and Radio stations require some level of experience and qualification from the various personnel who can work with them, there are a wide range of media outlets such as YouTube and music streaming websites such as Spotify where individuals can set up their own practices and effectively earn from it. As such media provides a wide range of career options to invest in.
Another strength of the media industry is its close tie to technology and technological development. According to Halbrooks (2019), advancements of technology lead to subsequent advancement of different forms, efficiency and effectiveness of media sites, channels and careers. For instance development of social media has impacted enhanced and highly effective and efficient marketing techniques and strategies as well as the development of revenue opportunities such as models and social media influencers. The media industry is also known for associated low costs of production and subsequent high revenues thereby making it a success guaranteed business venture.
Weaknesses and Threats
However the media also exhibits certain weaknesses that limit its attractiveness as an effective industry for investment. The industry is highly fragmented and lacks cohesion when it comes to content production and distribution. In addition the industry is not effectively regulated by significant government bodies leading to increased instances of misinformation especially with the social media platforms. Piracy and violation of intellectual property rights is also still a major problem and threat for the industry alongside lack of quality control for the content shared and uncertainties on account of rapid technological development (Gan, 2012).
Regardless, the industry still exhibits a multitude of opportunities that individuals can take advantage of for success and that enhance the attractiveness of the industry. Gan (2012) highlights that there is an increased interest of global investors in multiple media forms and channels which adds on to the future prospects of the industry. In addition a wide aspect of the digital media is yet to reach the entire globes population as only locations with access to internet can currently enjoy the services from the industry. This provides an effective gap in the economy for the industry. In addition new technological developments and innovation such as animations as well as distribution channels in mobile and internet open significant platforms and scope for the industry which is guaranteed to provide increaeed opportunities within the industries.
Ultimately the media industry is among the most influential industries in both the economy and culture of different countries within the world. The advancements in technology continue to enhance the industries development leading to the generation of new content and job opportunities to enhance the economy. In addition, the industry provides a wide range of options for virtually all individuals who are willing and able to invest in it. And given the significance of information sharing, analysis and usage in the contemporary social and economic environment, the industry is likely to continue holding significance in the global economy and therefore providing attractive opportunities for investments and career development.

"About 20,000 years ago, the Waikato changed course, taking a sharp left-hand lurch halfway down present-day Lake Karapiro, forsaking the Hauraki Plains it had built. The plains remained wet and boggy, developing large stands of kahikatea and vast tracts of manuka and rushes. Peat built up in this marsh, 11 metres deep in places, and the open water of the Firth of Thames lapped at this indistinct edge, flooding and ebbing with tides and changes in sea level over thousands of years."
Just noted due to some facts especially about the peat being 11 metres deep in places.
"... for everything the plains offered up, something was taken away—the forests, the marshland, the clear productive waters of the rivers and coast of the firth.
This zone of land and sea would become the Petri dish for a young nation bent on development, a great demonstration of the power of primary industries to rapidly create wealth in the new colony, and the cost that would exact on natural systems and habitats."
"In 1876, Premier Julius Vogel agreed to sell the ‘Piako Swamp’—about 70,000 acres in extent—to a group of investors for half the advertised price of five shillings (50c) per acre, £10,000 for the lot. George Grey, MP for Auckland City West, bitterly denounced the sale as a sweet deal for Vogel’s rich pals, when the government could have developed the land into 400 valuable farms. The investors proved unable to drain and tame the land as promised, and it was taken over by the Waikato Land Association."
More facts - how did Julius Vogel acquire the land? As private, or government? How was it acquired?
".. on the eastern side of the plains, sawmilling of the lowland forest had begun. In 1869, the Hauraki Sawmilling Company commenced operations at Turua and became one of the country’s largest mills. By 1900, most Coromandel kauri had been logged, and by the outbreak of WWI, there was little timber left on the plains."
Bagnall's Mill in Turua.
"But the removal of the kahikatea forests was just an entrée for the main course: draining and reclaiming the land. The Hauraki Plains Act of 1908, followed by the Waihou and Ohinemuri Rivers Improvement Act 1910, set up a colossal project involving stopbanks, canals, drains and pumping stations along with roads, bridges and wharves. Between 1910 and 1914, 15,000 hectares was reclaimed and sold as 270 ballot farms—Grey’s vision was finally in action. Dairying quickly became the preferred type of farming in the district and many small dairy factories sprang up."
"MY MOTHER AND her sisters grew up on a small dairy farm at Matatoki, backing on to the Waihou River. Till the day they died, they loved that place, speaking with the fondness of hindsight about trudging five miles each way to the main road for school, every day. "
These are the same stories I hear from my mother, aunties and uncles. Very proud of the hard work, and the 'trudge'.
"I wanted to find out whether this was fair in the Hauraki region, and how significant the impact of dairying might be on the adjacent Firth of Thames, often considered the most vulnerable part of the Hauraki Gulf. I’ve returned to my roots, visiting the lower plains to speak to dairy farmers still working the land in the spirit of my family a generation ago."
Maybe I need to be asking questions too, although I feel uncomfortable destroying their image. They are elderly, but younger farmers are coming up.
"Periodic bridges cross canals and rivers—most the colour of liquid mud."
The rivers are both this colour. It comes up in my work all the time.
"Barry Flint milks 1000 cows, split into several herds in the Miranda-Kaiaua area. His family have been on at least some of the property since the 1930s. Flint is proud that he’s lifted the carrying capacity of the land from 2.5 cows per hectare to 3.2, though it’s cost him $1000 a hectare to do so.
“Drainage is the big thing,” he explained. “I’m on heavy marine clays and by gently humping and hollowing the paddocks, we improve drainage considerably. I’m now growing twice as much grass as 30 years ago. I’ve also switched from Friesian cows to lighter Jerseys. They cause less pugging damage and suffer less footrot, which means they can forage better.
“My father used to get 400 pounds of butterfat to the acre, which was pretty good, but I now get 1000 kilograms of milk solids per hectare.”
Barry is a contemporary of mine. His mother was my teacher at primary school in Ngatea.
"Like elsewhere, potable water is a major issue on the plains. “It used to cost 22 cents per cubic metre, but now it’s increased to $1.88,” says Flint, who received an annual water bill from the council for more than $35,000 until he put down his own bore. That also cost $35,000, but promised to be only $3000 annually to run. He’s since discovered, however, that the bore water contains toxic levels of iron and boron, which costs as much to remove as the annual council water bill. “I’m stymied,” he says. With bitter irony, Flint also pays the council to maintain stopbanks and drains to keep unwanted water out."
All that drainage, all the costs, so many costs - we should have left the land alone. It was beautiful.
"As with much of the area, the farm was originally a peat bog, and as a consequence has settled between one and two metres over the past century. This has exposed ti-tree and large kahikatea stumps in places. "
PETER WEST’S HOUSE is perched on a knob above the western margin of the Hauraki Plains at Kaihere.
"Land, Air, Water Aotearoa—an association of councils, Massey University, the Cawthron Institute and the Ministry for the Environment—rates the Waihou at Te Aroha in the worst 25 per cent of similar sites for turbidity, nitrogen and phosphorous and in the worst 50 per cent for bacteria. Only on acidity does it score in the best 25 per cent. The net summary of these values by the ministry scores the Waihou as New Zealand’s third-most-polluted river."
There are a lot of facts and figures to do with contamination in this article, which I read but don't note. Figures are not my best subject.
"The fish-farm plan has some critics. Bill Brownell is a quiet, elderly American living near Kaiaua who has a long history with mussel farming and a passion for the environment. He is a fishery biologist and retired United Nations fishery development specialist, and edited Muddy Feet—Firth of Thames Ramsar site update 2004, an examination and collation of all that was known about the southern end of the firth.
“I don’t like the way economic and political considerations drive decision making,” he says."
How do we stop 'economic and political considerations' driving decision-making? This seems hard to answer - it was what drove the initial drainage of the Hauraki Plains, but look at the costs!
"The truth is that the firth may have been balancing on this tipping point for much of its history.
Before humans arrived on the plains, it was already a turbulent place. In the past 6500 years, the rivers of the plains have carried down so much volcanic debris from the many eruptions in the Bay of Plenty-to-Egmont zone that the southern shoreline of the firth has moved north by 14 kilometres. Given that volcanic ejecta is rich in minerals—including nitrogen from nitric acid produced in eruptions—leached minerals could have enriched the firth for millennia."
"One recent paper estimates that 44 million cubic metres of mud was deposited into the southern firth over the 36-year period to 1918, equivalent to around 280 years of present-day sediment loads."
"Dairy farming is the latest in a series of challenges thrown at the firth, and most likely not the worst. The increased flow of nutrients into marine systems can sometimes render short-term increases in productivity and fishery yields. Phytoplankton production depends on sunlight and small amounts of nutrients—including iron, nitrogen and phosphorous—which drives the whole food chain in coastal waters. More nutrients, more productive seas, to a point. The firth is attractive to wading birds, fish and shellfish because of its nutrient-rich seas, but it can be detrimental in the long term because of the potential for eutrophication, acidification and anoxia. Is there a better, more sustainable model for development on land and sea?"
"One doesn’t have to venture far to see a future that borrows from the past. In Ngatea, between kilometres of dairy farms, is a new model of sustainable farming… or, rather, a much older model.
On a blustery spring morning, I visited a three-hectare farm belonging to the Supported Life Style Hauraki Trust, which provides a ‘whole of life’ 24-hour service for people with special needs and severe brain injuries—there are 60 in its care. Most of the ‘life stylers’ live in homes in Thames, where a cafe serves as a focus for their activities. The farm—which has been operating for 12 years—produces much of the food for the cafe, and is a place for the life stylers to work and learn basic skills. All the waste comes back to the farm and is composted, along with manure that is collected from the animals."
And some hope, some goodness.
"In its own way, this mixed farmlet is probably more intensively farmed than most dairy farms, and its diversified products more valuable. While it’s not built on a commercial model, it harks back to an earlier time when farms were smaller and more diverse. Like in my mother’s days on these plains, when cream was taken down the river on a launch to the factory, when the farms were embedded in the communities they supported, and when the communities supported the farms—the sort of rural idyll that many still yearn for today, selling carefully grown food through farmers’ markets and roadside stalls.
It’s interesting to think that a return to the past might be a progressive alternative. Or that a low-input model might be more rewarding than a high-input one. Or that sheep—on which the foundation of farming in New Zealand was built—might offer opportunities for the future of dairy. Whatever the case, as the market for milk ebbs and flows, the running calculation of natural cost and commercial benefit will remain on everyone’s minds."
A balanced article it seems, looking at both sides. Its done so what can be done now to ensure we 'develop' it in the best way? An NZ Geo subscription coming up as there are many articles on the subject of the Hauraki Plains.

THIS FILE IS UNDER RECONSTRUCTION. THERE IS SIGNIFICANT DUPLICATION TO ELIMINATE. Read as best you can. In particular parts of the older file frame_reference_inertial_frame_basics.html still need to be incorporated.

Paul Spudis, a Planetary Institute in Houston, has been blogging the launch of India’s first lunar mission, Chandrayaan-1, which lifted off early Wednesday morning from India’s east coast.
Through the fog, into the fog (October 21, 8:00 a.m.)
I’m sitting in a hotel room in Chennai, India, attempting to recover from my jet lag. Houston to India is a 26-hour trip (one way) and although there’s plenty of time to snooze, I never sleep well on planes. Through my brain-fog, I have CNN International on in the room. At the top of the hour, there’s a detailed report on the Chandrayaan-1 mission to the Moon, now less than 24 hours away from launch. The report describes the mission as well as ISRO’s (the Indian space agency’s) four-year effort to build the spacecraft, and has interviews with key mission personnel, including Mylswamy Annadurai, the mission director, with whom I have formed a close friendship during the last few years. The news item is enthusiastic and thorough.
This matches my previous experience in India closely—the Indian people are genuinely excited about going to the Moon. I’ve talked to porters, room cleaners, taxi drivers, airport security people and many others during my seven trips here over the past four years. When they find out that I’m here to work on the Chandrayaan mission, they are not only very interested, but very excited and well informed—about space, the Moon, and India’s first journey into the solar system.
Over the past 50 months, we’ve designed and built our instrument, the Mini-SAR, which will fly to the Moon tomorrow on an Indian PSLV rocket. Mini-SAR is an imaging radar designed to map the poles of the Moon. Because radar provides its own illumination, Mini-SAR will map the dark areas near the lunar poles and search for evidence of the presence of water ice. This has been a controversial subject for the last decade. Now, we’re going to collect information on these deposits by mapping them from an instrument in lunar orbit, a first in the exploration of the Moon.
So now I sit here in Chennai, gazing out my hotel window into a gray, drizzly day. I hope the weather is better just up the coast, but the monsoon is with us and rain is a fact of life for tropical India for the next six months. ISRO is determined to get the mission on its way to the Moon (having been delayed several times), but they do have minimum launch conditions. I don’t know what they are, but I hope to find out this afternoon, as we head up the coast to the ISRO launch site, SHAR, in Sriharikota, about 80 kilometers from Chennai. Less than 24 hours—and counting!
A long and tedious journey (October 21, 4:00 p.m.)
No, I’m not talking about the trip to the Moon. I’m talking about the three-hour, 100-km (65 mile) car trip I’ve just endured from Chennai to the Indian space launch center. Solid bumper-to-bumper traffic for two hours—and that was just to get out of Chennai! India has almost (but not quite) achieved total traffic gridlock in their cities, and the time getting out of the center city was most of the trip. After we reached the suburbs, our speed of progress increased substantially.
The Indians launch their missions from a space center known as the Satish Dhawan Space Centre, or SHAR (from its location, Sriharikota). It sits on a low-lying spit of land that borders the Indian Ocean. They launch from here for the same reason that the Americans launch from Cape Canaveral—to ensure that any falling debris from an exploded rocket falls harmlessly into the ocean.
SHAR has a lot of the same ambiance as the Cape. It’s rather isolated (as was Cape Canaveral early in its history) and it’s flat, humid and warm. Scrub palm and thorny brush cover the landscape. Sea birds dot the tidal and mud flats as we drive across what seems like an endless causeway connecting the mainland to the spit on which the launch pad lies. One interesting difference here is that you must always keep your eyes on the road—you’re liable to run into goats, cows, chickens, pigs and an endless stream of stray dogs that run heedlessly across and along the road.
We’re staying at the ISRO (Indian space agency) guesthouse, a large block building that has a college dorm atmosphere. The big influx of foreign visitors arrived today; I would guess that we have about 20 to 30 visitors here. The press is also here in force. I saw around 15 remote vans and cars outside the main gate of SHAR, all getting ready to provide live coverage of tomorrow’s launch for Indian television.
As I was talking to Jitendra Goswami, the Chief Scientist for Chandrayaan-1, in the courtyard of the guesthouse, a reporter from Indian television saw us and ran over to get a talking head soundbite. Ben Bussey, a colleague from Johns Hopkins University’s Applied Physics Laboratory, is here with me, so we both did our turn on camera. It’s always interesting to see how these short interviews get edited; sometimes, they don’t make you look particularly intelligent.
The weather is currently looking a lot better. It rained very heavily here yesterday, creating large, deep puddles in the parking lot to go with the high humidity and heat. The rain is not as much a concern for launch as the possibility of lightning. Goswami told me that the meteorologists are measuring continuously the electrical potential of the cloud cover. Pictures of the launch pad at SHAR show it to be surrounded by four very large red metal towers, all designed to serve as giant “lightning rods” to protect the vehicle.
We’re waiting around now to hear the status of the mission. We’ll probably be briefed at dinner tonight, which will be held in the dining hall nearby. I’ve found out that cameras are banned from SHAR, so I won’t be taking any pictures of the launch. But it will be intensely photographed by ISRO personnel.
A warm, rainy morning (October 22, 7:30 a.m.)
I wake at 3 a.m. Might as well get up, as my alarm would be going off shortly anyway. It’s pitch dark out here in the Indian boondocks. The small television in my room tells me that the countdown is proceeding smoothly. It is now about two and a half hours until launch.
Having heard light constant rain all night as I slept fitfully, I go outside with some anticipation about a weather delay in the launch of Chandrayaan. Outside, it’s calm and beautiful; a last-quarter Moon smiles down on SHAR from directly overhead, and the brighter stars twinkle through some high clouds.
We may just get this thing off today! No time for breakfast as the VIP contingent boards several large buses in the dark. They are taking us out to a special launch viewing site set up especially for us. The drive takes about 20 minutes, even though it cannot be more than a few miles away. In the warm, close dark morning, we pass the occasional stone sign, like one for the “S-Band Precision Tracking Station.” We finally arrive at an old, abandoned rocket assembly tower, a site that has been re-configured into a special viewing area for the launch.
As I wander about this site, I suddenly see the PSLV rocket on its pad, about three miles away. It is floodlit and surrounded by lightning arrestors. We have a clear view of the vehicle and it’s only about an hour and a half until launch. ISRO has set up tents with large video screens, showing the activities of Mission Control. The countdown has gone so smoothly that it makes me slightly worried. Weather is no problem, as we have broken rain clouds at low altitude with hazy cirrus above. Our viewstand should give us a spectacular view of the flight as the rocket curves over the Indian Ocean (which I cannot see from here; dunes block the view).
I strike up a conversation with Raj Chengappa, the managing editor of India Today, a news magazine. He wants to know all about our experiment, the Chandrayaan mission, and the value of the Moon. We have a great time in this discussion, as he is very well informed and we talk about the long term value of the Moon. I give him my lunar “stump speech”—that the Moon is a stepping stone to the rest of the solar system, a source of materials and energy to enable new spaceflight capabilities. Chandrayaan is a key pathfinder in our voyage back to the Moon.
The countdown continues, slowly ticking by until it’s just two minutes to launch before I even realize it. I stop talking to my friends and the people around me. I want to immerse myself in what is about to come.
Fire, thunder and water (October 22, 8:15 a.m.)
As the voice over the loudspeaker counts below 20 seconds, I strain my eyes to look out over the coastal scrub between me and the gleaming white monument in the distance. As the count reaches below 5 seconds, I first see the bright orange glow of rocket ignition. It is surprising, even though I expected to see it. In the demi-light of early morning, it is startling. As the count reaches zero, I finally see the entire vehicle—until now I could only view the upper two-thirds. It’s a beautiful white needle, with a huge ball of orange flame beneath it.
It first rises very slowly, but when it clears the launch tower, it is absolutely spectacular! The launch pad is surrounded by a thick plume of white smoke around the base of the tower. As it streaks through the sky, it is still dead silent—the rocket sound has not yet reached us at our viewing site. The rocket quickly disappears into the low morning rain clouds—it’s moving astonishingly quickly. Then I hear the deep roar of the engines. The low frequencies of the engine noise beats on my chest. The crowd seems disappointed that the rocket vanished so quickly, but I suspect it will re-appear soon.
It does! A bright orange spotlight rises above the low clouds, arcing over the ocean in a magnificent streak. We have it in continuous sight only for a few tens of seconds, but from these glimpses, I can get a good feel for the trajectory, taking the rocket east-southeast over the Indian Ocean, toward orbit. When the rocket goes out of sight a second time, the crowd rushes into the nearby tents, which are set up with computer readouts and video of the Mission Control Center. We all sit in the plastic lawn chair seats provided inside a very pleasant, air-conditioned tent. A plot of time versus velocity and time versus speed is on the screen, showing the rocket as a bright spot over a curve of the planned trajectory. As near as I can tell, it is absolutely spot on the money. It’s moving like a bat out of hell—after only five and a half minutes, the PSLV has already achieved orbital velocity.
As we all gather in the tent to watch Chandrayaan reach orbit, an enormous downpour occurs outside. The heavy monsoon rain pounds our tent roof. The space gods have smiled upon on us this day—the rain held off until after we had left Earth.
We all watch the trajectory information intently. Now, a mere 20 minutes after launch, Chandrayaan is on its way to the Moon. The crowd relaxes and applauds enthusiastically. It has been a memorable morning. This was my third launch; I attended the launch of Clementine to the Moon in 1994 (from Vandenberg AFB, on a surplus Titan II, the rocket that launched the Gemini astronauts). I also went to a space shuttle launch in 2001, a particularly memorable launch that arced over a full Moon, rising above the Atlantic. Both of those were striking experiences.
But I think this one actually exceeds the other two. The tension released after a launch is enormous. You work on an experiment for years, nursing it through financial and technical difficulties. You baby-sit it during testing and integration with the spacecraft. So much rides on something so dangerous. You have visions and nightmares of exploding rockets and time and effort wasted.
I do not have those thoughts this morning. This warm, rainy day in southern India, I feel wonderful. Our spacecraft got a superb ride this morning. It’s on its way to the Moon. Now I think ahead—what new adventures await us on the remainder of this voyage of discovery?
On its way (October 23, 4:00 a.m.)
After the launch, we all come back to the guesthouse for a late breakfast and celebration. Team Chandrayaan, the dedicated group of ISRO scientists and engineers who have worked on this mission, are all excited and jocular. There was tremendous pressure on them to deliver this mission, and with a perfect launch they are well along the road to success. I run into Madhavan Nair, the head of the Indian Space Agency. He is clearly tired, but very happy to have a “perfect” launch under his belt. I offer my congratulations and express our team’s gratitude for giving us a good start to the mission. For the first time, I also meet Chandra Dathan, the SHAR center director. He is all smiles and is clearly basking in the exultation of the moment. We know that the mission has only begun, but having a picture perfect launch has created a success vibe. Good karma for a space mission is always welcome.
After lunch, we make the long drive back from SHAR to Chennai. I am exhausted, having never really caught up on sleep since arriving two days earlier. But knowing that Chandrayaan is successfully on its way to the Moon is a great feeling. That evening, the Mini-SAR team celebrates the day’s events with a few gin and tonics, the one undeniable contribution to western civilization by the departed British Raj. (They contain quinine—anti-malarial, don’t you know.)
The print and electronic media are filled with stories on Chandrayaan. Few space missions get this level of attention in America. The launch and orbit inject was magnificent, and the stories cover the mission objectives, spacecraft instruments, and flight profile. While at SHAR, I was interviewed by two different Indian television networks. One of our team members, Bill Marinelli of NASA, tells me that one of those interviews just aired, although he caught only the end of it. The press coverage is overwhelming, positive and appears to be demand-driven, not an attempt to impose or simulate an excitement that doesn’t really exist. Today, all of India is proud of its space program. It has the right to be.
Back at the hotel in Chennai, we prepare to leave India and fly back home late that evening. We have lots of work ahead of us before Chandrayaan gets to the Moon next month. Next week, we’ll have our first opportunity to turn on our instrument, point the antenna at the Earth and calibrate it using the large radiotelescopes at Greenbank, West Virginia and the giant hole-in-the-ground dish at Arecibo in Puerto Rico. We will carefully map out the signal pattern of the Mini-SAR antenna and test its performance in space. We will then use these calibration tests to learn how to extract the maximum amount of knowledge from our data.
So far, so good. Now, we begin to look forward to the Moon. | <urn:uuid:55a7c138-7303-4235-8c16-eec234cc9084> | CC-MAIN-2024-51 | https://www.smithsonianmag.com/air-space-magazine/india-aims-for-the-moon-85887310/ | 2024-12-06T23:40:12Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066421345.75/warc/CC-MAIN-20241206220301-20241207010301-00000.warc.gz | en | 0.958608 | 3,354 | 2.53125 | 3 |
Black business owners and entrepreneurs have always faced pervasive challenges in their pursuit of success, including the need for more capital and limited access to opportunities for advancement and property ownership. Unlike their white counterparts, Black entrepreneurs are hindered by a lack of funding, perpetuating a cycle of inequality. The inability to access resources such as property ownership further exacerbates this disparity, denying them the same avenues for progress.
But property ownership is more than just a practical necessity — it’s a source of power and freedom.
To understand why property ownership matters so much for Black entrepreneurs, one needs to look at the history of their struggle to secure real estate amid discrimination and oppression. Only then can financial institutions take action to help Black entrepreneurs achieve property ownership and create real, long-lasting change.
The Importance of Property Ownership for Black Business Owners and Entrepreneurs
Owning property is a critical component of achieving business success. Property ownership provides stability and security, allowing business owners to control their location and avoid sudden rent increases, lease terminations, or landlord disputes that could disrupt their operations.
It is important to recognize that increased fees and rent on apartments and homes create additional challenges, impacting the rental history and credit of prospective borrowers. By owning property, business owners can mitigate these challenges and establish a stronger foundation for their financial stability and growth.
Owning commercial real estate allows for capital appreciation, the increase in property value over time. However, systemic barriers have disproportionately limited this opportunity for Black business owners, hindering wealth creation. By owning property, Black entrepreneurs can accumulate equity for funding future ventures, investing in assets, and passing down generational wealth — fostering economic empowerment.
Thirdly, property ownership can help level the playing field for Black business owners and entrepreneurs. By creating a foundation for future success, Black business owners can take control of their financial destiny and compete on an equitable footing with their white counterparts. This is especially critical in light of the significant racial wealth gap that exists in the United States.
Racial disparities persist in commercial real estate ownership, with only 3% of Black households and 8% of white households owning commercial properties. Furthermore, there is a significant wealth gap within ownership, as the average value of commercial property owned by white households is $34,000, while for Black households, it is merely $3,600. By promoting property ownership among Black business owners and entrepreneurs, financial institutions can help to narrow this gap and create a more equitable society.
Historical Barriers for Black Entrepreneurs and Property Ownership
The history of Black entrepreneurship in the United States is a story of struggle and resilience. For centuries, Black entrepreneurs have faced significant obstacles to owning their own business property, which has limited their opportunities for growth and wealth creation.
During the Jim Crow era (c. 1877 – c. 1950), for example, many Black-owned businesses were located in neighborhoods that were often undervalued and underdeveloped by discriminatory policies and practices. Although the property was more affordable in these areas, it became difficult for Black business owners to secure financing from banks that were often reluctant to invest in these neighborhoods.
Black entrepreneurs have not only had to overcome systemic discrimination and lack of access to capital, but they have also faced obstacles in acquiring and maintaining property. Real estate agents historically steered Black entrepreneurs away from white neighborhoods, limiting their options for ownership. Government-backed loan programs, like the Federal Housing Administration (FHA), were also not accessible to Black entrepreneurs, making it difficult to access capital and acquire property.
Even when Black entrepreneurs could secure property, they faced higher interest rates, insurance premiums, limited access to utilities and infrastructure, and discriminatory zoning laws. These barriers made it challenging for Black entrepreneurs to build and sustain successful businesses, and many were forced to operate out of leased or substandard properties, further limiting their growth potential. The cumulative effects of these obstacles have resulted in significant disparities in property ownership and wealth between Black and white entrepreneurs.
The Inspiring History of Successful Black Entrepreneurs in America
Despite significant obstacles, notable Black entrepreneurs have achieved remarkable success. Take Robert Gordon, who was born into slavery but managed to purchase his freedom and establish a thriving coal yard in Cincinnati. Despite facing fierce competition, Gordon's determination allowed him to overcome challenges and sustain his business.
Annie Malone also stands as a pioneering figure among Black women entrepreneurs. In the early 20th century, she launched successful ventures, including a hair product line and other cosmetic products, becoming one of the first Black women to amass a multimillion-dollar fortune.
Today, it is important to recognize that the achievements of present successful individuals have been built upon the toil and struggles of such trailblazers. However, it is equally crucial to acknowledge that many of the same challenges persist for aspiring entrepreneurs.
While these stories are inspiring, they do not reflect the reality for many Black business owners who continue to face persistent challenges and barriers. In 2019, there were a total of 5,771,292 employer firms (businesses with more than one employee), of which only 2.3% (134,567) were Black-owned, even though Black people comprise 14.2% of the country’s population.
Furthermore, the COVID-19 pandemic disproportionately affected Black-owned businesses, which declined by 41% from February 2020 to April 2020, while White-owned businesses declined by only 17%.
These disparities demonstrate the urgent need to create equal opportunities for Black entrepreneurs. At this critical juncture, it is essential that financial institutions actively support and uplift Black-owned businesses and work to address the systemic inequalities that have historically held them back.
How Banks Can Support Black Entrepreneurs
To truly support Black entrepreneurs in their pursuit of property ownership, banks must take concrete steps to address systemic barriers and provide the necessary resources and assistance. Here are some strategies that banks can implement to equalize property ownership opportunities.
Provide Access to Capital
Black entrepreneurs face a significant obstacle when it comes to building and expanding their businesses: securing adequate funding. The ability to acquire and maintain property is a crucial component of this, and without sufficient capital, many Black entrepreneurs find themselves unable to grow and maximize profitability.
To combat this issue, banks have a critical role to play in supporting Black entrepreneurs. They can do so by offering loan programs specifically tailored to the needs of this demographic or by partnering with community organizations to provide financial education and resources.
It's important to note that the statistics on this issue are alarming. According to CNN, in the first half of 2021, just 1.2% of total U.S. venture capital went to Black entrepreneurs. This disparity highlights the urgent need for targeted loan programs that can address this inequality.
By addressing these challenges and providing equal opportunities, banks can enable Black entrepreneurs to overcome financial barriers and achieve their business goals. This, in turn, can contribute to a more equitable and prosperous economy for everyone.
Eliminate Discriminatory Practices
Discriminatory lending practices have been a longstanding issue in the banking industry, causing immeasurable harm to Black entrepreneurs. Despite progress in recent years, a 2017 study revealed that Black loan applicants still face obstacles such as higher interest rates, lower loan amounts, and less favorable terms compared to their white counterparts.
Banks must recognize their role in perpetuating these harmful practices and take swift action to put an end to them. To create a better lending environment, banks must train their loan officers on equitable lending practices that do not discriminate based on race, gender, or any other factor. This is not only the right thing to do but also a legal obligation under fair lending laws.
Additionally, banks must ensure that their loan underwriting processes are transparent and equitable, with clearly defined criteria and requirements for obtaining funding. Black entrepreneurs should not be left in the dark about what it takes to secure financing and build their businesses.
Offer Technical Assistance
Owning property is a multifaceted endeavor, and Black entrepreneurs face distinct hurdles that can impede their advancement. It is important to recognize that the lack of generational wealth among Black business owners often hinders their access to foundational resources and knowledge needed for success, such as navigating permits, licenses, and networking opportunities typically associated with white privilege. To drive meaningful change, banks must proactively offer essential technical assistance to help bridge these gaps and empower Black entrepreneurs to achieve their aspirations.
One critical area where banks can provide assistance is business planning. Black entrepreneurs may require guidance in developing a viable business model and creating a realistic budget. With the right support, they can achieve financial stability and long-term growth.
In addition, banks can assist Black entrepreneurs with real estate negotiations, from identifying suitable properties to negotiating fair prices and terms. By providing this level of support, banks can help Black entrepreneurs overcome common hurdles and secure the resources they need to thrive.
Lastly, legal and regulatory compliance is another critical area where banks can offer assistance. Obtaining permits, licenses, and meeting zoning requirements can be a daunting task, but with the right guidance, Black entrepreneurs can overcome these barriers and focus on building their businesses.
Partner With Community Organizations
Banks have a responsibility to empower Black entrepreneurs by forming partnerships with community organizations that serve their needs. By collaborating with such organizations, banks can offer a more comprehensive suite of services that cater to the unique challenges and opportunities faced by Black entrepreneurs.
These partnerships should include working with organizations that provide business coaching and mentorship, which can be particularly valuable for early-stage ventures that require guidance and support to navigate the complexities of running a business. Additionally, partnering with organizations that offer networking opportunities can help Black entrepreneurs to expand their networks and gain access to new markets and funding sources.
Another critical area where banks can partner with community organizations is in affordable housing and community development initiatives. By supporting these efforts, banks can help to strengthen local economies and create sustainable growth opportunities for Black entrepreneurs and their communities.
Support Policy and Advocacy Efforts
Banks have a unique opportunity to drive meaningful change by using their influence to support policy and advocacy efforts aimed at dismantling systemic barriers to property ownership and wealth creation for Black entrepreneurs.
This involves taking bold action to advocate for changes to laws and regulations that perpetuate racial disparities in lending and investing in initiatives that promote economic empowerment and racial equity.
By leveraging their resources, banks can become powerful agents for positive social change, helping to create a fairer and more just society for all.
Banks have a crucial role to play in supporting Black entrepreneurs to achieve property ownership through innovative models like collective ownership. Collective ownership allows multiple stakeholders to share ownership and control of a property, which can reduce the individual risk and cost of acquiring and maintaining real estate.
One example of this is the Coliseum project in Minneapolis, which involved the transformation of a historic theater and adjacent buildings into affordable housing and commercial space for local businesses. The financing for this groundbreaking project was made possible through a coalition of community development corporations (CDCs) and nonprofit community development financial institutions (CDFIs).
By providing participation loans shared among multiple lenders, banks can join these efforts to support collective ownership projects in historically disadvantaged neighborhoods.
Stearns Bank’s Vision for Closing the Racial Gap in Property Ownership
Under the leadership of Skalicky and the unwavering commitment of the Stearns Bank executive management team, Stearns Bank has initiated multiple initiatives in support of the Minority Depository Institutions Advisory Committee's (MDIAC) mission. Stearns Bank takes pride in being at the forefront of creating a more inclusive and equitable financial system for Black entrepreneurs and underserved communities.
In a groundbreaking partnership with the African Development Center (ADC), a community development financial institution based in Minneapolis, Stearns Bank is actively working to foster the growth of businesses, facilitate wealth creation, and promote reinvestment in African immigrant-owned businesses within Minnesota. By providing crucial resources such as access to capital, financial education, business training, and mentorship, Stearns Bank empowers Black entrepreneurs to achieve their business goals and drive economic growth in their communities.
While these efforts signify Stearns Bank's commitment to supporting Black entrepreneurs in their pursuit of property ownership and wealth creation, it is essential to acknowledge that there is still much work to be done in order to achieve genuine racial equity in the real estate sector.
Open and honest conversations about the systemic barriers that persist, as well as advocating for the rights of Black business owners and entrepreneurs, are crucial for financial institutions, lenders, and community members alike. It is through these collective efforts that our country can make significant strides toward a more just and equitable future for all. | <urn:uuid:ab9fb38d-09ae-4756-81e7-23c3bb14a550> | CC-MAIN-2024-51 | https://www.stearnsbank.com/resources/blog/the-power-of-property-ownership-for-black-business-owners-and-entrepreneurs | 2024-12-07T00:00:06Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066421345.75/warc/CC-MAIN-20241206220301-20241207010301-00000.warc.gz | en | 0.95656 | 2,562 | 2.6875 | 3 |
Sean was walking endlessly along the beach. "How long have I been lost here???" he asked out loud. But nobody answered. Sean was alone. Lost in a desert island, with nobody to rescue him. "What is this beach?! Where am I?". He was walking, again and again, until suddenly...
"Wait a minute! I've already seen this red rock! I must be at the entry to the beach!"
He then realized...
"I'm not lost! I'm running in circles!"
Dear reader, welcome to the world of Loop Closure!
Loop closure is a fundamental algorithm in Robotics and Computer Vision. But where it's the most important is in SLAM. So before I jump in loop closure, a 1-min intro to SLAM.
The 1-min Intro to SLAM (Simultaneous Localization And Mapping)
Have you ever been to Manhattan? It's a place I really love. And in part because it's really convenient for walking, wandering, and discovering new places. So picture yourself in Manhattan, and imagine being asked to walk in the city, and every time, keep track of where you are.
So you start in Time Square, and join the 5th Avenue in a few minutes. You then walk along the 5th Avenue towards Central Park, and as you get closer, you're perfectly able to update your position on a map.
This is SLAM.
It stands for Simultaneous Localization And Mapping, because you're simultaneously creating a map of Manhattan and locating yourself in it.
Now imagine walking for 20 minutes along the 5th Avenue, starting at Abercrombie, and then suddenly after 20 minutes, being asked "Which number are you EXACTLY?".
Then you don't know. Even if you counted the number of steps you took, there is a slight risk of error. Who knows? Are you number 100? 102? 122?
This is what we can call accumulated errors.
And this is why Loop Closure is important. Loop closure is the equivalent of seeing the Apple Store along the 5th Avenue, and then immediately thinking "Oh, it's Apple! We're at 767!"
And robots need it!
Because Loop Closure is what helps a robot understand that an object has already been visited, and therefore the robot will update its location and the map accordingly. Imagine being blindfolded, and then transported at the back of a car with armed kidnappers, only to be released near the Eiffel Tower. Suddenly, you realize "Hey, I know this place!" and you're (somewhat) relieved.
This is loop closure! It's highly involved in SLAM, but also in Augmented Reality, and even Object Tracking. By the way, you can learn more about SLAM in my course on SLAM which covers many of the algorithms and help you run these.
An example? See how this robot drives, and then suddenly recognize a place, and update the entire map by aligning the locations.
Which leads us to:
How Loop Closure Works
There are several loop closure techniques. And in fact, I talk about many of them in my SLAM course. In this post, I'm going to give you a brief intro. There are lots of ways to classify the algorithms, but because I'm a simple guy, let's simply classify them as:
- Vision Based
- LiDAR Based
Vision Based Loop Closure Detection (Visual Features)
When we have a camera, the first things we want to look at are features. Feature-based methods rely on identifying distinctive features in the environment, such as corners or edges, and matching them between different sensor data frames.
The algorithms for this are called SIFT (Scale-Invariant Feature Transform), SURF (Speeded-up Robust Features), ORB (Oriented Fast and Rotated BRIEF), etc.... If you want an intro to these techniques, you can check my post Visual Features & Tracking: The Fundamentals.
In a traditional feature matching process, like for example in Object Tracking, we're doing something like this:
- Detect the features using a feature detector (SIFT, SURF, ORB, AKAZE, ...)
- Describe the features using a feature descriptor (SIFT, SURF, ...)
- Match the features in the current image with the memory features (from previous images), this using RANSAC or other similar algorithms
- Do your application: tracking, loop closure, etc...
An example here:
So let's note this as our pillar: if we want to detect previously visited location, we'll do it via visual features.
In SLAM, what we mainly do is to build what's called a Bag-Of-Words.
Bag Of Words
In Simultaneous Localization and Mapping (SLAM), we want to represent the visual features as a fixed-length vectors and match them efficiently to detect loop closures. And we want the features we're looking at to be matched based on some sort of dataset, because it'd make things so much easier. If you look at a window, you know it's a window because you've seen hundreds of windows before. But if you look at an unknown object, matching it is much harder.
In a Bag of Words approach, we're matching our descriptor features to visual words in a fixed-size vocabulary. By matching the features to a pre-trained vocabulary, we're able to do the loop closure detection much faster (computations are more efficient).
So it goes like this (simplified):
- Feature Detection (SIFT, SURF, ORB, ...)
- Feature Description (SIFT, SURF, ORB, ...)
- Bag of Words: The raw descriptors are assigned to the nearest visual word in the vocabulary, and a histogram of visual words is constructed for each image. This histogram represents the BoW vector for the image, which is a fixed-size representation of the image features. This BoW vector can then be used for efficient matching and loop closure detection.
It kinda looks like this:
And then we're matching the vectors together with the previous keyframes when we need to run place recognition.
So here's an example here with an algorithm called ORB SLAM:
So this is for Visual SLAM Algorithms, and it works in known environments, because we're working with a Dataset. Sometimes, the environment might change, it may rain, or it may be dark, and often, our Bag-of-Word will fail. This is why there are also algorithms such as FAB-MAP (Fast Appearance Based Mapping) that can work better in dynamic environments or complex environments with lots of variability.
Next, let's move to LiDAR:
LiDAR Based Loop Closure Detection (Direct Methods)
In a LiDAR, we don't extract any feature. We work directly with the point clouds. Direct methods use the raw sensor data to estimate the robot's position and recognize a previously visited location. If you've heard of algorithms like ICP, or Bundle Adjustment, or Pose Graph Estimation, this is it. So let's see some of them:
Iterative Closest Point (ICP)
For example, the Iterative Closest Point Algorithm (ICP) is a method used to align two point clouds iteratively by minimizing the distance between their corresponding points. It is commonly used for 3D Point Cloud Registration tasks, such as aligning point clouds from LiDAR sensors or depth cameras. ICP can work well in environments with limited feature points, such as indoor environments or dense forests.
The ICP algorithm starts by finding the corresponding points between the current point cloud and the previously recorded point clouds in the map. These corresponding points are used to estimate the transformation between the current point cloud and the map using a least-squares approach. The estimated transformation is then used to align the current point cloud with the map.
Bundle Adjustment, on the other hand, is an optimization technique that estimates the camera's intrinsic and extrinsic parameters by minimizing the reprojection error of a set of 2D image points onto a 3D model.
It can work well in environments with a high number of feature points, such as urban environments or open fields. Where we use it the most is probably 3D Reconstruction.
Similarly to how we've done in the Feature-Based techniques, loop closure detection will be done by matching and aligning points from time (t) with points from time (t-1).
What about Deep Learning?
Hey! Are we crazy? We haven't talked about Deep Learning, Transformers, and all these models until now! What's up?
Well, let's just say it's a world that is highly bayesian, and that prefers traditional approaches. But it doesn't mean Deep Learning isn't involved. For example, we discussed matching detected features with ORB or SIFT, but we can also detect these features with Convolutional Neural Networks.
Similarly, these days, there are SLAM algorithms based entirely on Deep Learning; but I gotta tell you; this is mostly in research for now, and most SLAM applications, and even most loop closure detection applications are based on what I shared so far.
Loop Closure Candidates
An important point in loop closure is deciding how to match features from time t and t-1. There are TONS of reasons why this could go wrong. You could look at a point cloud of a house, but it's not the same house you think you've visited. You could look at a barrier, but it's not the right one. A window, but it's a building with 100s of windows.
There are solutions to matching features, or as we call them, loop closure candidates. One of them is to use the Bag-of-Words / FAB-MAP. But to improve this, there are other things we can do:
- Geometric Constraints: The geometric constraints between the current observation and the previously visited locations can be used to generate loop closure candidates. For example, the distance and orientation between the current observation and the previously visited locations can be compared, and the ones with the closest match can be selected as loop closure candidates.
- Time-Based: We can include time-based methods that will use the temporal information in the robot's trajectory to generate loop closure candidates. For example, the robot's position and orientation at different time steps can be compared to identify the closest matches, or the time intervals between the robot's visits to different locations can be used to generate loop closure candidates.
- Region-Based: Similarly, you can set a Region of Interest (ROI) to determine what you'll match, and don't match. This can save computations, as well as potential errors.
Earlier, we've seen how to detect loop closure candidates, and how to confirm that a place has been seen before.
In the sentence "Hey! I've seen this rock! I must be at the entry of the beach!" — we have covered the "Hey! I've seen this rock!" part. But not the "I must be at the entry of the beach!".
This second part belongs to map correction.
How does the map correction work? It depends on the type of SLAM algorithm you're using. Loop Closure "Detection" is about detecting the position of landmarks you've already seen. But map adjustment is another module in SLAM.
There are usually several types of SLAM algorithms, for example, Graph-SLAM is about optimizing a graph based on landmarks. When using graph SLAM, map correction will be done via graph optimization.
But if you're using EKF-SLAM for example, which uses an Extended Kalman Filter, map correction will be done by incorporating the information from loop closures and observations of landmarks into the Kalman filter's state estimate. If you're into Kalman Filters, it's about the update step.
So this isn't really part of loop closure, this is what happens right after!
We've seen a few things concerning the loop closure detection process, let's review them:
- Loop closure is a sub algorithm of SLAM that is about identifying previously visited locations and using them to correct the accumulated errors in the robot's pose estimation.
- Loop closure detection can be achieved using different methods, including geometric constraints, appearance-based methods, and time-based methods.
- Loop closure candidates are potential matches between the current observation and the previously visited locations in the map.
- False positives in loop closure can be caused by similar-looking locations, lighting changes, sensor noise, or other factors. For that, we can use geometric constraints, region constraints, and even better algorithms like FAB-MAP.
- We mainly run loop closure detection on images and LiDAR point clouds. For this, we use Visual Features on images, or algorithms like ICP or Bundle Adjustment on point clouds. | <urn:uuid:fb3e6b3d-9184-4d63-bf70-cad4effaf62e> | CC-MAIN-2024-51 | https://www.thinkautonomous.ai/blog/loop-closure/ | 2024-12-06T23:09:10Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066421345.75/warc/CC-MAIN-20241206220301-20241207010301-00000.warc.gz | en | 0.946027 | 2,716 | 2.5625 | 3 |

imagine threatening your partner or good friend by counting "One…
Two" if he or she did not do what you wanted?
the big issues in schools today is "bullying." Parents and teachers struggle
daily with how to stop this behavior. Without realizing it, adults teach
bullying behavior to children by modeling it when they use the threat of their
physical size or power to make children do things. When I hear a parent
counting "One… two" at a young child, I always wonder what the child
has been told will happen if the parent gets to three. Is it the threat of a
spanking, being yelled at, time out, abandonment (I'm going without you) or the
withdrawal of love and approval? Whatever the threat may be, I rarely hear
"three." As intended, the threat of what will happen if the parent
gets to three usually compels the child to do whatever it is the parent is
telling the child to do. Parents use threats to get children to cooperate
because that was what adults so often modeled when we were growing up. Most of
us are familiar with the phrase "or else." We did what we were told
out of fear even if we didn't know what the "or else" would be.
counting may appear to be a magic form of discipline, there is no magic in
threats. Children know that adults are bigger and more powerful than they are.
They comply in self-defense. If the only way we can get children to do what we
ask is by intimidating them with our greater physical size and power, how will
we get them to do as we ask when we are no longer bigger and stronger? "Ask
the parents of any teenager if counting still works. Not only do threats no
longer work, they've learned to use the same means to make others do what they
parents see a child's uncooperative behavior as a challenge to their authority.
Once we understand that uncooperative behavior is usually caused by a child's
unmet need or an adult's unrealistic expectation, we don't have to take the
behavior so personally. Parents and children often have different needs.
Sometimes our needs or schedules conflict with our children's needs. Children
who are deeply absorbed in play will not want to interrupt their play to go
with us to the bank or the store before it closes. When a parent needs to do
one thing and a child needs to do something else there is a conflict of needs.
This conflict of needs turns into a power struggle when parents use the power
of fear instead of the power of love.
bond or connection parents have with their children is their most powerful
parenting "tool." A strong bond is created over time when parents
lovingly and consistently meet a child's early needs. Threats communicate,
"what you think, feel, want or need is not important." Threats undermine
the parent-child bond. When we learn to resolve our "conflicts of
needs" in ways that show children that their needs and feelings matter, we
strengthen the bond and avoid many power struggles. If we want to teach
children to love instead of hate, we must learn to use conflict resolution
skills in our daily interactions with children. Just as children learn bullying
from what adults model, they can learn conflict resolution and problem solving
skills from what we model. When children learn the skills from how we treat them
at home they will bring those skills to their relationships at school.
young children can learn conflict resolution if we model it. An older sibling
can be taught to find another toy to exchange with their younger sibling
instead of just snatching their toy back. When two children want the same toy
at the same time we can help them "problem solve" a solution. When
there is a conflict of needs because the parent wants to do an errand and the
child just wants to stay home and play we can say "let's problem solve to
see if we can find a way for us both to get what we need." Maybe the child
could take the toy in the car or perhaps the errand could wait until tomorrow.
When the parent is ready to leave the playground and the child wants to stay longer
we can suggest a compromise of five more minutes and doing something fun when
we get home. Often it's not that the child doesn't want to leave as much as it
is that she doesn't want the fun to end. When we teach children that everyone's
needs are important by honoring their needs they learn to honor the needs of
will be times that we won't have the time or the resources to meet a child's
need. There will be times that even after honoring the child's need; the child
is still unable to cooperate. At those times it is important to communicate
that parents have needs too and even though it makes the child unhappy we do
have to go now and then allow the child to have his feeling about having to
leave. It is never OK to tell a young child that you will leave without them.
Threatening a child with abandonment terrifies a child. When a child has a
tantrum about leaving it may not be about leaving the playground at all.
Leaving may just be the last straw that unleashes the day's accumulation of
little frustrations. The child may just need to cry to empty out the stresses
of the day. A child will be able to move forward much more readily when we can
say "I know you're sad and it's OK to cry" than if we say "Stop
that crying or I'll give you something to cry about!" When the crying is
done the child will usually feel better and be more able to cooperate.
children's needs are met and nothing is hurting them they are usually
delightful to be with. Whenever a child responds negatively to a reasonable
request we need to look for the conflicting need.
know how our needs are in conflict we can try to solve problem. I have learned to say, "When you behave
that way I know something is wrong, because we love each other and people who
love each other don't treat each other this way.

parent has an interesting and often conflicting duty: keep the child safe, but
paradoxically let the child explore the very challenging, often dangerous world
around them. If I distract the child by making myself part of the danger I am
not going to be a very effective teacher, guide and protector of my child. If I
teach my child that the world, and parents or adult caregivers are dangerous
people then I teach my child that being dangerous yourself is a way to survive.
Or, and most sadly, I will teach the child that passivity and compliance are
all one has to survive with. The child either grows up being me or in reaction
to me. In either case I have crippled and limited my child no matter how
wonderfully obedient he or she may seem.
get the world we believe in, and if we believe that children must submit to
harsh authority and that they are basically evil and must be controlled then we
will get a world of people who behave as though this is true. Where families
raise their children with love and gentleness and do not call them names and
yell at them, where they are not slapped, pinched, punched and whipped, we have
children who are confident in their ability to manage in a world they see as
full of exciting choices and fulfilling experiences.
thoughtful person looking at the belief systems of those in prisons or in our
mental or social services programs gets the point. Our prisons are full of
those who believe that to be dangerous is how to survive in the world. And our
mental health and human service systems are full of those who have only
passivity and compliance as their coping method. Researchers have given up on
trying finding violent offenders in prisons who were not spanked or beaten or
punished as children. If you are a parent who spanks think about how you were
raised and what you may be visiting on this child you beat that they will do to
theirs and theirs to theirs. It is a harsh legacy that, I have come to believe,
will destroy our planet in time.
the child who is raised with love and attention who I expect will view the
world assertively, with courage and thoughtful examination of the universe on
their own who I want to govern in my place when their turn comes around.

"Your son is so polite," a friend once said when Jason was five.
I beamed. It felt like I was the one being praised, but I had never specifically taught him such skills. Through John Holt's books, I learned that all I needed to do was set an example of kindness (especially kindness towards Jason himself) that he could emulate.
Setting an example of social skills is all that is needed. Demanding kind behavior through threats or punishment is itself unkind - all it can do is confuse and frustrate the child. Yet many parents have not learned this. Children are so commonly mistrusted, misunderstood and mistreated in our culture that rudeness towards them has come to seem normal. Adults rarely treat each other the way they often treat children. What would happen if an adult were treated the way many children are? How would an adult feel if asked "What do you say?" after receiving a gift? Yet many children are put on the spot in just this way.
When I was five, one of my aunts, the matriarch of our family, gave me a beautifully wrapped birthday present. I eagerly opened it, only to find a plain, dark brown bathrobe. I don't remember if I said anything. I'm sure that I didn't feel like thanking my aunt, and I must not have, because she was dismayed, and my mother took me to my room for a scolding. Now I had two problems: I was disappointed with the gift and angry with my mother for not understanding my feelings. I never wore the bathrobe. And I was miserable every time we visited my aunt.
Some of life's rules are clearly given and easy to understand, such as those involving safety ("Always look both ways when crossing a street") but many are unwritten and can be complicated ("Say 'thank you' with enthusiasm if someone gives you a gift, even if you don't like it.") |
Many of life's rules
are unwritten. |
Unwritten social rules, like thanking someone for a gift, are not inborn. Rules have to be learned, and like any other kind of learning, the use of force, punishment, or embarrassment only distracts from the intended lesson. To complicate things further, unwritten rules can be very different in different cultures. In Japan, gifts are given on many occasions, and there are strict rules. For example, the recipient of a gift is expected to open it later in private; this avoids awkwardness if the gift is not well-liked. If only my aunt had been Japanese!
What did I learn from this experience? I learned that my mother would have preferred me to lie to my aunt than to be honest about my feelings. I learned that happy occasions can turn unhappy in a moment, and sometimes there is no one there to help. It was a painful way to learn about manners.
Had my mother taught me beforehand to say something honest yet helpful ("Thank you for remembering my birthday!"), the situation could have been avoided, and perhaps I could have gotten to know my aunt better. I might have grown to understand how important social graces were to those of her generation.
The Best Way to Teach a Child Manners
Like everything else that children learn about relationships, manners are best and most easily taught by example, because children naturally watch and copy the adults around them. Ideally, parents will show by their own behavior how to treat others with kindness and genuine gratitude. After all, the whole reason for social manners is kindness. Sadly, many parents teach manners through coercion, just as they were taught in their own childhood. And parents care about how their children's behavior will be perceived, because it reflects on them. Yet isn't it confusing to the child to be taught kindness through unkindness? If a child forgets to thank someone for a gift, the parent could simply say, "Thank you so much for thinking of him! How nice that you remembered!" This will model to the child how to express gratitude in an appropriate way.
Children naturally copy
the adults around them. | Many children don't know what to say when given a gift, especially if they don't like it, and in their confusion say nothing, or express their disappointment in a negative way. Ideally, the parent can prevent such awkward moments by explaining gently beforehand what the social customs are, and why they are important. Perhaps the most helpful lesson for the child is that "thank you" does not always mean "I love your gift," it can simply mean "I'm happy that you thought of me". Role-playing an anticipated gift-giving scene (perhaps with the fun of switching roles) before a party or a meeting with a relative can help to give a child more self-confidence. |
The best way to teach a child manners, or any other social skill, is by our own modeling, especially by the way we treat our own child. If a child is thanked for the small gifts and heartfelt kindnesses he gives to us and others, he will naturally give thanks when he is ready, on his own timetable. A "thank you" means little if it has been coerced - it only has meaning when spoken from the heart.

there room for children in our society? Most of our culture is structured for
adults, and children are unwelcome or even excluded. Children spend most of
their time in school and school-related activities, where parents are not
harsh attitude toward children can be most evident when shopping; many store
personnel seem to view every child as a potential source of trouble. The
presence of a child is tolerated – as long as he is perfectly quiet, doesn't
touch anything, and doesn't look as though they'll hurt themselves. I suspect,
though, that it isn't so much the child's potential suffering that storekeepers
are concerned about, but rather their own: they are afraid of being sued! This
fear can be unreasonable to the point of lunacy. A child, at age seven was once
loudly warned in a grocery store, "Get down from that ledge! You'll hurt
yourself!" This dangerous ledge was exactly five inches from the floor.
we look closely at a child at play, we can see that children have the same
instinct for self-preservation that adults have, and a good sense of what they
can handle. Why, then, are children so mistrusted? At those times when
something does need to be said about a child's behavior in public, this is
often done in a harsh, impatient, and disapproving tone. Yet adults too
sometimes behave in inappropriate ways in public - such as dropping dirt on the
floor and not in the dust bin. If the adult is corrected at all, such a request
is usually made with the utmost cordiality. Do adults deserve more consideration
children venture out in public, they are rarely spoken to, unless, like
soldiers, they are asked for their names and class. If circumstances are such
that children appear in public during school hours, they are asked, almost
crossly, "Why aren't you in school?!" How would an adult respond if
asked, "Why aren't you at work?"
are expected to be infinitely patient during boring errands and conversations,
and never interrupt adults - no matter that children's conversations can be far
and away the more fascinating. Wouldn't you rather hear about Disney world, or
how you are loved Ben 10.
their delightful ways, children in public places are treated as though they are
invisible, and their needs are often considered irrelevant. In making their
needs known to others, they are at a particular disadvantage, because of their
youth and inexperience. Unlike senior citizens, who also encounter unfair age
discrimination, there are no child spokespersons to elicit empathy for their
condition. Who has not seen a distraught infant or child whose tears are
ignored by angry parents and indifferent strangers? If an adult were crying in
public, would not everyone be concerned? If an animal were obviously suffering,
would everyone walk past?
churches, while teaching of love within families, segregate children from the
most meaningful activities. Housing discrimination against families is still a
problem in many areas, where children are placed in the same category of
undesirables as pets.
things be different? Sometimes they are, All children behave as well as they
are treated - just like adults. Why is it so difficult for adults to understand
this? After all, we have all been children. How have we forgotten so soon what
it is like to be a child in an adult world? Children deserve to be treated in
the same way that we wish to be treated – with kindness and understanding,
dignity and respect. As an author wrote, "Human beings should be treated
like human beings." We are all human beings, and, in a sense, we are all
children. Some of us have just been around a little longer.

We should try to get out of the habit of seeing little children as cute. By this I mean that we should try to be more aware of what it is in children to which we respond and to tell which responses are authentic, respectful, and life-enhancing, and which are condescending or sentimental. Our response to a child is authentic when we are responding to qualities in the child that are not only real but valuable human qualities we would be glad to find in someone of any age. It is condescending when we respond to qualities that enable us to feel superior to the child. It is sentimental when we respond to qualities that do not exist in the child but only in some vision or theory that we have about children.
In responding to children as cute, we are responding to many qualities that rightly, as if by healthy instinct, appeal to us. Children tend to be, among other things, healthy, energetic, quick, vital, vivacious, enthusiastic, resourceful, intelligent, intense, passionate, hopeful, trustful, and forgiving - they get very angry but do not, like us, bear grudges for long. Above all, they have a great capacity for delight, joy, and sorrow. But we should not think of these qualities or virtues as "childish," the exclusive property of children. They are human qualities. We are wise to value them in people of all ages. When we think of these qualities as childish, belonging only to children, we invalidate them, make them seem things we should "outgrow" as we grow older. Thus we excuse ourselves for carelessly losing what we should have done our best to keep. Worse yet, we teach the children this lesson; most of the bright and successful ten-year-olds I have known, though they still kept the curiosity of their younger years, had learned to be ashamed of it and hide it. Only "little kids" went around all the time asking silly questions. To be grown-up was to be cool, impassive, unconcerned, untouched, invulnerable. Perhaps women are taught to feel this way less than men; perhaps custom gives them a somewhat greater license to be childlike, which they should take care not to lose.
But though we may respond authentically to many qualities of children, we too often respond either condescendingly or sentimentally to many others - condescendingly to their littleness, weakness, clumsiness, ignorance, inexperience, incompetence, helplessness, dependency, immoderation, and lack of any sense of time or proportion; and sentimentally to made-up notions about their happiness, carefreeness, innocence, purity, nonsexuality, goodness, spirituality, and wisdom. These notions are mostly nonsense. Children are not particularly happy or carefree; they have as many worries and fears as many adults, often the same ones. What makes them seem happy is their energy and curiosity, their involvement with life; they do not waste much time in brooding. Children are the farthest thing in the world from spiritual. They are not abstract, but concrete. They are animals and sensualists; to them, what feels good isgood. They are self-absorbed and selfish. They have very little ability to put themselves in another person's shoes, to imagine how he feels. This often makes them inconsiderate and sometimes cruel, but whether they are kind or cruel, generous or greedy, they are always so on impulse rather than by plan or principle. They are barbarians, primitives, about whom we are also often sentimental. Some of the things (which are not school subjects and can't be "taught") that children don't know, but only learn in time and from living, are things they will be better for knowing. Growing up and growing older are not always or only or necessarily a decline and a defeat. Some of the understanding and wisdom that can come with time is real - which is why children are attracted by the natural authority of any adults who do respond authentically and respectfully to them. |
We too often respond
condescendingly or sentimentally. |
One afternoon I was with several hundred people in an auditorium of a junior college when we heard outside the building the passionate wail of a small child. Almost everyone smiled, chuckled, or laughed. Perhaps there was something legitimately comic in the fact that one child should, without even trying, be able to interrupt the supposedly important thoughts and words of all these adults. But beyond this was something else, the belief that the feelings, pains, and passions of children were not real, not to be taken seriously. If we had heard outside the building the voice of an adult crying in pain, anger, or sorrow, we would not have smiled or laughed but would have been frozen in wonder and terror. Most of the time, when it is not an unwanted distraction, or a nuisance, the crying of children strikes us as funny. We think, there they go again, isn't it something the way children cry, they cry about almost anything. But there is nothing funny about children's crying. Until he has learned from adults to exploit his childishness and cuteness, a small child does not cry for trivial reasons but out of need, fear, or pain.
Once, coming into an airport, I saw just ahead of me a girl of about seven or eight. Hurrying up the carpeted ramp, she tripped and fell down. She did not hurt herself but quickly picked herself up and walked on. But looking around on everyone's face I saw indulgent smiles, expressions of "isn't that cute?" They would not have thought it funny or cute if an adult had fallen down but would have worried about his pain and embarrassment.
There is nothing funny about children's crying. | The trouble with sentimentality, and the reason why it always leads to callousness and cruelty, is that it is abstract and unreal. We look at the lives and concerns and troubles of children as we might look at actors on a stage, a comedy as long as it does not become a nuisance. And so, since their feelings and their pain are neither serious nor real, any pain we may cause them is not real either. In any conflict of interest with us, they must give way; only our needs are real. Thus when an adult wants for his own pleasure to hug and kiss a child for whom his embrace is unpleasant or terrifying, we easily say that the child's unreal feelings don't count, it is only the adult's real needs that count. People who treat children like living dolls when they are feeling good may treat them like unliving dolls when they are feeling bad. "Little angels" quickly become "little devils." |
Even in those happy families in which the children are not jealous of each other, not competing for a scarce supply of attention and approval, but are more or less good friends, they don't think of each other as cute and are not sentimental about children littler than they are. Bigger children in happy families may be very tender and careful toward the little ones. But such older children do not tell themselves and would not believe stories about the purity and goodness of the smaller child. They know very well that the young child is littler, clumsier, more ignorant, more in need of help, and much of the time more unreasonable and troublesome. Because children do not think of each other as cute, they often seem to be harder on each other than we think we would be. They are blunt and unsparing. But on the whole this frankness, which accepts the other as a complete person, even if one not always or altogether admired, is less harmful to the children than the way many adults deal with them.
Much of what we respond to in children as cute is not strength or virtue, real or imagined, but weakness, a quality which gives us power over them or helps us to feel superior. Thus we think they are cute partly because they are little. But what is cute about being little? Children understand this very well. They are not at all sentimental about their own littleness. They would rather be big than little, and they want to get big as soon as they can.
How would we feel about children, react to them, deal with them, if they reached their full size in the first two or three years of their lives? We would not be able to go on using them as love objects or slaves or property. We would have no interest in keeping them helpless, dependent, babyish. Since they were grown-up physically, we would want them to grow up in other ways. On their part, they would want to become free, active, independent, and responsible as fast as they could, and since they were full-sized and could not be used any longer as living dolls or super-pets we would do all we could do to help them do so.
Or suppose that people varied in size as much as dogs, with normal adults anywhere from one foot to seven feet tall. We would not then think of the littleness of children as something that was cute. It would simply be a condition, like being bald or hairy, fat or thin. That someone was little would not be a signal for us to experience certain feelings or make important judgments about his character or the kinds of relationships we might have with him.
| Children do not think of each other as cute. |
Another quality of children that makes us think they are cute, makes us smile or get misty-eyed, is their "innocence." What do we mean by this? In part we mean only that they are ignorant and inexperienced. But ignorance is not a blessing, it is a misfortune. Children are no more sentimental about their ignorance than they are about their size. They want to escape their ignorance, to know what's going on, and we should be glad to help them escape it if they ask us and if we can. But by the innocence of children we mean something more - their hopefulness, trustfulness, confidence, their feeling that the world is open to them, that life has many possibilities, that what they don't know they can find out, what they can't do they can learn to do. These are qualities valuable in everyone. When we call them "innocence" and ascribe them only to children, as if they were too dumb to know any better, we are only trying to excuse our own hopelessness and despair.
Some infants who were just learning to walk. I used to think their clumsiness, their uncertain balance and wandering course, were cute. Now I tried to watch in a different spirit. For there is nothing cute about clumsiness, any more than littleness. Any adult who found it as hard to walk as a small child, and who did it so badly, would be called severely handicapped. We certainly would not smile, chuckle, and laugh at his efforts - and congratulate ourselves for doing so. Watching the children, I thought of this. And I reminded myself, as I often do when I see a very small child intent and absorbed in what he is doing and I am tempted to think of him as cute, "That child isn't trying to be cute; he doesn't see himself as cute; and he doesn't want to be seen as cute. He is as serious about what he is doing now as any human being can be, and he wants to be taken seriously."
What is cute about being little? | But there is something very appealing and exciting about watching children just learning to walk. They do it so badly, it is so clearly difficult, and in the child's terms may even be dangerous. We know it won't hurt him to fall down, but he can't be sure of that and in any case doesn't like it. Most adults, even many older children, would instantly stop trying to do anything that they did as badly as a new walker does his walking. But the infant keeps on. He is so determined, he is working so hard, and he is so excited; his learning to walk is not just an effort and struggle but a joyous adventure. As I watch this adventure, no less a miracle because we all did it, I try to respond to the child's determination, courage, and pleasure, not his littleness, feebleness, and incompetence. To whatever voice in me says, "Oh, wouldn't it be nice to pick up that dear little child and give him a big hug and kiss," I reply, "No, no, no, that child doesn't want to be picked up, hugged, and kissed, he wants to walk. He doesn't know or care whether I like it or not, he is not walking for the approval or happiness of me or even for his parents beside him, but for himself. It is his show. Don't try to turn him into an actor in your show. Leave him alone to get on with his work." |
We often think children are most cute when they are most intent and serious about what they are doing. In our minds we say to the child, "You think that what you are doing is important; we know it's not; like everything else in your life that you take seriously, it is trivial." We smile tenderly at the child carefully patting his mud pie. We feel that mud pie is not serious and all the work he is putting into it is a waste (though we may tell him in a honey-dearie voice that it is a beautiful mud pie). But he doesn't know that; in his ignorance he is just as serious as if he were doing something important. How satisfying for us to feel we know better.
We tend to think that children are most cute when they are openly displaying their ignorance and incompetence. We value their dependency and helplessness. They are help objects as well as love objects. Children acting really competently and intelligently do not usually strike us as cute. They are as likely to puzzle and threaten us. We don't like to see a child acting in a way that makes it impossible for us to look down on him or to suppose that he depends on our help.
Children do not like being incompetent any more than they like being ignorant. They want to learn how to do, and do well, the things they see being done by the bigger people around them.

Nurturing Compassion from the Beginning
by Jan and Jason Hunt
We all hunger for peace. Yet far too often this seems to be just a dream, hopelessly out of reach. Instead of the peaceful life we all want, we have strife in our families, in our communities, and between our nations. We lose hope of anything better, and begin to think that nothing will ever change. Our dream of peace remains elusive.
This is a hard dream to relinquish, because it began at birth. Every infant beams when there is peace in the home, and looks perplexed and cries when there is not. To an infant, conflict is a puzzle. As infants, we not only want everyone to get along, we expect it. We are born expecting peace. Even as adults, we are shocked and saddened by every new story of brutality. We still believe that life can and should be peaceful. But we know that each day, in far too many places, there will be conflict, fighting, killing, and even war. If we are all peace lovers in our infancy, what makes us so divisive in adulthood? What goes wrong? How can it be fixed?
We wake each morning with the hope that things will change, but every day there is another sad and shocking story. We are all bewildered, and want to understand what went wrong. It seems to be human nature to focus on the most recent events, not those further back in time. So we wonder what could have been done on the days before a tragedy that might have prevented it. What last-minute interventions could have made a difference? What could have been done differently at the scene to save lives? | The best prevention is always the earliest. |
There is nothing wrong with these kinds of questions - they may help to prevent future acts of violence from taking place. But to reduce the potential for violence in general, it may be more constructive to look at the earliest links, not the most recent ones. While there are many factors that can lead to violence, the best prevention is always the earliest - the one that keeps the first domino from falling. |

Interestingly enough, the term is almost exclusively applied to children – seldom to adults. We never hear people say:
- ''My husband misbehaved yesterday."
- "One of our guests misbehaved at the party last night."
- "I got so angry when my friend misbehaved during lunch."
- "My employees have been misbehaving lately.''
Apparently, it's only children who are seen as misbehaving - no one else. Misbehavior is exclusively parent and teacher language, tied up somehow with how adults have traditionally viewed children. It is also used in almost every book on parenting I've read, and I've read quite a few.
I think adults say a child misbehaves whenever some specific action is judged as contrary to how the adult thinks the child should behave. The verdict of misbehavior, then, is clearly a value judgment made by the adult - a label placed on some particular behavior, a negative judgment of what the child is doing. Misbehavior thus is actually a specific action of the child that is seen by the adult as producing an undesirable consequence for the adult. What makes a child's behavior misbehavior (bad behavior) is the perception that the behavior is, or might be, bad behavior for the adult. The "badness'' of the behavior actually resides in the adult's mind, not the child's; the child in fact is doing what he or she chooses or needs to do to satisfy some need.
Put another way, the adult experiences the badness, not the child. Even more accurately, it is the consequences of the child's behavior for the adult that are felt to be bad (or potentially bad), not the behavior itself.
When parents and teachers grasp this critical distinction, they experience a marked shift in attitude toward their children or students. They begin to see all actions of youngsters simply as behaviors, engaged in solely for the purpose of getting needs met. When adults begin to see children as persons like themselves, engaging in various behaviors to satisfy normal human needs, they are much less inclined to evaluate the behaviors as good or bad.
Accepting that children don't really misbehave doesn't mean, however, that adults will always feel accepting of what they do. Nor should they be expected to, for children are bound to do things that adults don't like, things that interfere with their own "pursuit of happiness.'' But even then, the child is not a misbehaving or bad child, not trying to do something to the adult, but rather is only trying to do something for himself.
Only when parents and teachers make this important shift - changing the locus of the problem from the child to the adult - can they begin to appreciate the logic of non-power alternatives for dealing with behaviors they don't accept. | <urn:uuid:d1132bcc-70c6-46a8-a17b-40d05371d93e> | CC-MAIN-2024-51 | http://hhcinitiative.blogspot.com/ | 2024-12-08T00:28:55Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066433271.86/warc/CC-MAIN-20241207224914-20241208014914-00800.warc.gz | en | 0.982575 | 7,666 | 2.75 | 3 |
When it comes to Hindu works of political theory and political statecraft, it can be found in the various treatises throughout Hindu religious literature. Most of these treatises and stories are too difficult to be digested by the masses, especially if look back to times around the 8th century. There are two works of literature that allow for ease of consumption of these ideas. They are the Pancatantra and the Hitopadesa. The Pancatantra is the older of the two dating to around the 3rd century CE, but this is inconclusive as the stories presented are seemingly much older and this is possibly the first instance of them being written down. The Hitopadesa, on the other hand, does not come into existence until between the 8th and 12th century. The Hitopadesa was written by someone named Narayana and it was meant to teach young princes statecraft. This collection of fables sets to explain political statecraft by utilising animal tales. The collection itself is split into four sections, the acquisition of friends, the separation of friends, war, and peace. (Pinncott 1). The way the stories are told within the Hitopadesa is an old sage telling different stories of animal interaction to four young princes. In this way of storytelling, the Hitopadesa shares a lot of similarities with other fable collections, such as Aesop’s Fables. Also, it is considered to be what inspired the fables we see in collections like Aesop’s Fables (Srinivasan 70).
If we look at each of the sections that the Hitopadesa is broken into, we start to notice repeated themes, for example, choose your friends wisely. Each of these themes is easily explained through the stories presented in each section of the Hitopadesa. In the first section of the Hitopadesa, which is referred to as the acquisition of friends, there is a story of a vulture, a cat, and some birds. In this story, the vulture lives in a great tree with the birds and one day a cat approaches the tree and the birds wake the sleeping vulture to deal with the cat. The cat using honeyed words convinced the vulture to allow him to stay within the tree. As the days passed, the cat proceeded to eat the young birds without the vulture ever taking notice. The birds noticed that their young were slowly starting to disappear and they decided to investigate. The cat caught wind of this and snuck its way out of the tree without any notice. Upon discovering the remains of their young ones in the vultures hollow the birds proceeded to peck the vulture to death because they believed that the vulture was the one responsible for this (Pinncott 12-14). There are a few morals to this story, one of which is that one should never treat someone you hardly know as a friend, this is because one can never fully trust anyone upon their first meeting. Another moral that can be taken from this story is that one should trust their instincts. At first, the vulture did not want to take the cat into its hollow because it knew that the cat was a malicious being but because of the cat’s honeyed words the vulture was persuaded and that eventually led to its demise. This story is one of many that take place in the first section of this collection that deal with how to acquire the right friends.
Another story in this first part of the collection that deals with how to choose the right friends is about a deer, a jackal, and a crow. In this story, the jackal approaches the deer with intent to feast on its flesh and asks to be the deer’s friend, the deer accepts. When they return to the deer’s hovel, they are greeted by the deer’s old friend, the crow, who asks why the deer has made friends with the jackal and warns the deer of this decision. Listening to the crow’s advice but not heeding it, the deer continues to be friends with the jackal. The jackal one day convinces the deer to eat from a plentiful field of corn, which the deer does and fattens up. Then one day it becomes caught in a snare set by the farmer of the field. The jackal sees this and decides to wait for the human to return to kill the deer and take some of its flesh, then the jackal will devour what is left behind. Luckily for the deer, the crow comes looking for the deer and finds it caught in the snare and they then proceed to devise and execute a plan that will free the deer and kill the jackal (Pinncott 11-16). The moral of this story is like that of the vulture, the cat, and the birds, that one should never make a friend out of someone you just met and know little about. These two stories, along with the rest of the stories within the first section are highly cynical and seem to eschew the idea that no one is innocent until proven guilty and holds aloft the concept of nature over nurture.
The second section of the Hitopadesa deals with the separation of friends. In this section, there is a story of a washerman’s donkey and dog, in which the house of the washerman is being robbed and the dog refuses to bark to wake the master. The donkey notices this and inquires as to why the dog refused to bark to rouse the master, the dog responds that because the master is neglecting him he will neglect the master. The donkey takes great offence to this and scolds the dog and decides to bray to rouse the master. The donkey accomplishes arousing the master but it also scares away the robber. The master then beats the donkey to death for rousing him for what the master who failed to see the robber saw as nothing (Pinncott 36-37). The moral presented in this story is that it is better to mind one’s own business. This moral is seen in another story about a monkey who perished when it removed a wedge between two beams (Pinncott 36).
Another story in this section deals with monkeys and a bell. In this story, a robber from a certain village steals the temple bell and runs into the forest where he is attacked by a tiger who was curious about the sound. The tiger killed him leaving the bell on the ground. Eventually, a group of monkeys came by and picked up the bell and at night would ring it continuously because they enjoyed the music. When the villagers went in search of the strange bell ringing they found the corpse of the robber and heard the ringing of bells and decided that the forest was haunted by an evil spirit that would kill and then joyously ring a bell. One woman from the village did not believe that this was the case and ventured into the forest, and discover that it was not an evil spirit but a group of monkeys who were ringing the bell. So, with intelligence and courage, she received some gold from the king and used that gold to purchase various fruits and nuts. Then she tricked the monkeys to come down from their trees and eat the food, while they were eating happily the woman retrieved the bell and saved the town from the evil spirit (Pinncott 44). The moral presented in this story is that through intelligence and courage, one can overcome all odds and should not be afraid of small trifles. The morals presented in this section of the Hitopadesa deal with intelligence winning over all else, that one should approach all situations with these abilities least one should end up like the monkey. One should also not interfere with the disputes of another lest they end up like the donkey and one should also have the intelligence and courage to find the truth like the woman and the bell.
The third section of the Hitopadesa deals with war. In this section, there is a story of a herd of elephants whose watering hole has dried up and they fear that they will die of thirst, but they hear of a lake that has yet to dry up in another jungle. It was then decided that the elephants would travel to this lake in this far away jungle as to not perish from thirst. When the herd of elephants saw the lake, they stampeded over to it, crushing hundreds of rabbits under foot. The rabbits who retreated to their king needed a plan that could drive the elephants from their land. So, the rabbit king went to speak with the king of the elephants and unable to reach the king of the elephants the rabbit king decided to climb a nearby hill and proclaimed that he was a messenger sent from the moon god. The rabbit king informed the elephant king that he had angered the moon god by drinking from his sacred lake. This terrified the elephant king so much so that he took his herd and left, leaving the rabbits alone with their lake (Pinncott 60-61). The moral that is presented in this story is that wit can win over might. This moral is an important lesson when it comes to warfare, in that it teaches that any battle can be won with the right strategy.
Another story from this section of the Hitopadesa is about a soldier who offers his services to a king for a hefty sum, the king then decides to pay him for 4 days upfront and observes closely what the man does with the gold. The king finds that the man gave half of the gold to the gods and the Brahmin, a quarter to the poor and less fortunate and kept the last quarter for his own sustenance and pleasure. He did this all while maintaining his position at the gate always unless relieved by royal permission. After a few days, the king received word of weeping coming from the front gate; the king promptly sent the man to investigate and upon approaching what was a weeping woman, he had a vision. In that vision, he learns that the king has but three days to live and to save him, the man must behead his first-born son. The man does this but also takes his own life than his wife proceeds to take hers; the king discovers this and laments offering up his own life to save the three of them. The Goddess appears and lets him know that his sacrifice was not required and she was simply testing him. Upon hearing this, the king asked if the three of them who sacrificed themselves to be revived. Upon their revival, the king asked the man about the source of the weeping and the man replied, that it was just a woman who fled when he approached (Pinncott 72-74). The moral of this story is that the greatest man does not brag about his deeds, but remains quiet and accepts them as a part of himself. This moral also plays nicely with the concept of warfaring in that one who does not boast of his accomplishments will not receive any challenges, and when he is challenged he will have a fortune at his side.
The last section of the Hitopadesa deals with peace. In this section, there is a story of a crane and a crab. In this story, there is a crane that can eat from a pond whenever he needs to but as he grows older, he becomes unable to catch the fish of the pond and begins to starve. The crane then devises a plan to make it seem like the pond is drying up and that he knows of another pond that is further away that is safe. The crane then offers to carry the residences of the lake to the pond but because he is old, he must rest between voyages. On the first voyage, he takes some fish but instead of heading to the pond, he heads to a nearby hill and eats the fish, the crane repeats this for a while until he regains his strength back. One day, a crab wishes to be carried to the pond and the crane becomes excited thinking he can try some new food takes the crab. During the voyage, the crab asks the crane if they are about to reach the pond, but the crane simply replies that he will eat him and that there is no pond. Angered by this, the crab promptly grabs the cranes neck and breaks it, killing the crane. The crab returns to the pond and tells the pond of what was transpiring (Pinncott 84-85). The moral of this story is that greed in excess is harmful. This moral can be used when bartering for peace because sometimes if you are bartering for peace and you have the most to gain from the peace deal, you must not be too greedy because you might also have the most to lose.
The Hitopadesa is one of the most translated works of Hindu literature and is still extremely relevant today. The lessons and teachings held within the Hitopadesa are easily applied to contemporary problems that youth or people, in general, can use. Like the European collection of fables called Aesop’s fables, the Hitopadesa is used to teach Sanskrit literature and writing to young Hindus learning their first language or for a student who seeks to learn Sanskrit, it is an excellent starting point (Pincott iii).

Realism is a cornerstone of international politics and a crucial theory in this field of study because it assists in our comprehension of the difficulties we currently face as well as the modern world. With the conviction that all states are driven by their own self-interests, prioritizing territorial integrity and securing political autonomy, realism helps to emphasize this role of the nation-state. The greatest way to discuss international policy and national interests is through realist viewpoints. It shows how problems such as economic globalization are now a component of a state’s foreign policy and national interests. This demonstrates that states typically pursue their own vested interests rather than common goals. A state cannot take part in international politics without having an interest, as the European gas issue also demonstrates. A silver lining was that the U.S. and its allies were presented with the opportunity to impose sanctions as a result of the invasion of Ukraine to stymie Russia’s economy and weaken its attacks on Kyiv. In retaliation, Moscow cut off the oil supplies to European countries that imposed sanctions. The construction of the Nord Stream pipeline has been supported by the British and American governments on the grounds that the then-planned Turkey-Austria gas pipeline cannot efficiently supply gas to Europe. These defenses are based on a gas dispute with Turkey, where Russia delayed supply due to diplomatic considerations. As a result of the potential benefits to them in the future, the U.S. and the UK have been backing the development of the Nord Stream pipeline. Russia cannot be forced to give up Nabucco because it is also a major power.1
The events of cutting oil supply by two million barrels a day by OPEC+ sent shock waves across the world, ringing a bell of the oil embargo of 1973. Although this is a different story, the repercussions carry a similar impact on the U.S. and Europe. By imposing an oil embargo in 1973, the Arab branch of OPEC briefly succeeded in wielding oil as a political tool to exert pressure on the West. As a result, the Gulf states’ interests do not coincide with those of the U.S., paving a way for animosity between the two sides. This jarring awakening forced Western countries to reconsider their energy strategies, which eventually turned the greatest strength of Arab oil producers into their biggest weakness. Although the 1973 oil crisis was not the first instance of oil being used as a weapon and is unlikely to be the last, it was the one that had the biggest impact on countries that depended on oil. This raises a few questions: What does the future hold for U.S.-OPEC relations, especially U.S.-Saudi Arabia relationship? What is the impact of this energy crisis on the upcoming midterm elections?
Deep oil production cuts approved by OPEC+ rocked the energy markets, placing the cartel on a collision path with the United States. The OPEC cartel decided to limit their daily output by 2 million barrels. The action raises the possibility of additional inflationary pressures on an already struggling global economy. The ramifications are extensive, affecting everything from the price of oil to how the U.S. and Saudi Arabia will interact in the future. This decision is anticipated to increase gas prices at the pump, possibly dealing Biden a severe blow before the November midterm elections, while also assisting Russia in overcoming a partial European oil import sanction. The timing of the cuts for the Democrats could not have been worse. Falling gas prices and voter fervor regarding access to abortion following the Supreme Court’s decision to uphold the procedure’s ban have managed to blunt what was formerly a sharp Republican weapon and increased the chances for Democrats in the upcoming November elections. But with the OPEC+ declaration, crude and gas prices have now reversed direction and increased significantly, which is woeful tidings for Democrats given that gas costs frequently have a significant impact on the American psyche. The political fallout for Biden and Democrats might be significant as they try to maintain a majority in the midterm elections later this month. The U.S. continuing to release crude from its emergency oil stockpile has irked the Gulf oil producers who are members of the cartel. The implementation of a price limit on Russian oil exports has also been spearheaded by Washington. The Gulf states worry that, should the idea succeed, the price cap might eventually be extended to them or might lower the price of their own oil.
Cutting production will increase prices and the value of the dollar in ways that undermine the Fed’s goals, including stifling inflation, if oil supply shocks increase demand for dollar liquidity in a time of growing dollar scarcity and rising interest rates are suppressing demand generally.
The U.S. Dollar Index (DXY) is close to the record highs of the dot-com bubble era at 112.7 (most recently 114.5). Some fear that we are entering a period of hyper-dollarization, which could see us surpass the previous high of 120, possibly reaching 150 or even 175, smashing other currencies, before collapsing, with significant ramifications for the dollar’s status as a supranational currency and the overall state of the global economy.
The Fed is currently experimenting with new methods to encourage more liquidity while increasing interest rates and purchasing dollars, but these strategies are undercut by production cuts. Additionally, when the value of the dollar rises and more than 90% of the world’s oil transactions are conducted in dollars, the money that the OPEC+ countries gain is worth more and more. These victories enable them to accumulate cash while also offsetting losses brought on by unstable bond markets, global economic downturns, risks posed by the euro and the pound, and continuous Fed activities that are not likely to stop anytime soon. Concerning the effect on Europe, it will oblige governments to increase their subsidies to tamp down still-growing energy prices, placing them in a more perilous financial situation.
Again, it will increase the cost of USD by increasing the demand for dollar liquidity in a market that is already under pressure, which will put downward pressure on European currencies and other currencies. Currently, it is difficult to envision the West lifting its sanctions against Russia. Similar to this, the Fed is dedicated to reducing inflation regardless of the effects on the world economy. The OPEC+ cuts are unpopular in Europe for the simple reason that they will raise already prohibitive energy prices. More than this, though, some people fear that it would further weaken the EU, which was founded in part to oppose US hegemony, and that this will force Europe farther closer to the U.S. and its efforts to decouple from China.
The decision by OPEC+ to reduce production by 2 million barrels per day, coming at a time when the world economy is still suffering from the effects of Russia’s invasion of Ukraine and Western sanctions, shows that the cartel and Russia share certain common interests as oil producers, and that oil and politics are now inextricably linked.
The claim that Saudi Arabia has allied with Russia is absurd. Instead, events affecting the global oil market, including Western sanctions, rising US interest rates, and a decline in demand, have prompted OPEC to act in ways that reflect the interests of major oil producers, including Russia. The EU did, however, just agree to a price ceiling on Russian oil shipments and a ban on the majority of crude oil imports. Russia will thus lose market share. Moscow’s financial losses will be mitigated by OPEC+ reduction. These measures harm the economies of the U.S. and EU. Thus, this policy benefits Russia as a side effect.
Despite all these influences, the cartel’s unexpected severe oil production cuts will also tighten supply to the West, which is already suffering from record energy prices. The prices of gasoline and diesel would undoubtedly rise due to a lack of supplies, which will further worsen inflation. Oil-producing countries benefit from a sharp decline in output, but consumers may see significant price increases. It is even successful in stopping the flow of funds to the Kremlin thanks to the cap on Russian crude. President Biden is compelled to think about increasing market supplies from the US Strategic Petroleum Reserve. One of the key Western methods for eroding Moscow’s war chest has been chewing away at US and EU restrictions on Russian energy.
The OPEC+ decision would, however, benefit Russia as an oil exporter, since Moscow will not have to cut a single barrel of output as it is already producing well below the agreed level while profiting from higher oil prices. By establishing that OPEC+ has essentially sided with the Kremlin, which enables Moscow to refill its coffers and to limit the effects of US and EU sanctions, the ramifications for Russia and, by extension, for the war in Ukraine will become clear.
Reaction of the United States
The OPEC+ group was charged by the White House with aligning with Russia and harming the world economy. Calling for a more responsible measure to increase domestic energy production, pointing to potential reactions that would include additional releases from the national Strategic Petroleum Reserve as required, Biden will continue to oversee releases from the Strategic Petroleum Reserve in Washington. Given the OPEC+ decision, it presented the United States with two golden opportunities to limit the impact. After the White House denounced the action, three legislators unveiled a bill that would effectively declare Saudi Arabia to be no longer an ally of the United States and order American soldiers to leave both Saudi Arabia and the United Arab Emirates. It is still unclear if Congress will take it up before the year. In my opinion, that is highly unlikely, given that Saudi Arabia is an essential security partner of the United States in its quest to establish Israel as a welcome country among Arab states.
Along with that, the Biden administration promised to consult Congress on how to limit OPEC’s grip over oil pricing. The announcement called for the revival of the so-called “NOPEC” law, which would target oil cartels by enabling the Department of Justice to file lawsuits against nations for engaging in anti-competitive behavior. Additionally, Congress is seeking ways to boost US energy outputs and lessen OPEC’s influence over world prices. The Bill would classify OPEC as a cartel and subject its participants to the Sherman Antitrust Act. The US legislation may subject OPEC members and allies to legal action for coordinating supply disruptions that drive up petroleum prices globally.
Energy analysts think that Saudi Arabia, the leader of OPEC and a close ally of the United States, may end up paying for the drastic production cuts, especially in light of Biden’s indication that Congress will soon try to limit the influence of the Middle Eastern-dominated organization over energy pricing.
In a nutshell: in the short-term, the global energy crisis stems from the Russia-Ukraine war. War involving a major oil producer always roils the global oil market. Global oil markets are always volatile when a major oil producer is engaged in a war. The disruption has been compounded by Western sanctions on Russian oil, including the G7’s forthcoming oil price cap, which has (in part) invited tit-for-tat retaliation by Russia and OPEC oil producers. Overall, this has caused a spike in spot market prices as well as a fear of future market scarcity, which is raising prices even more. While in the long-term, the pressure on pricing is caused by inadequate transitional investment in O&G production assets, as markets worry that these assets would become stranded assets, as nations and markets shift toward renewables and green technologies.
In terms of policy, the best combination would be to help vulnerable low- and middle-income households and small- and medium-sized businesses with subsidies and transfer payments along with rewards for conserving energy and penalties for overusing it.
The world’s biggest oil-importing nations are attempting to harness the power of energy politics to hold oil exporters accountable when they cross certain boundaries, suggesting that this weapon has evolved into a double-edged sword. Therefore, coming forward, Riyadh could become a victim of its own favored weapon of choice: energy politics, if it defies Washington’s demands.

604-681-0882In the world of heat pumps, understanding the function of the defrost cycle is essential. In this section, we will provide an introduction to heat pump defrost cycles and explain why they are necessary for proper heat pump operation.
Heat pumps are highly efficient heating and cooling systems that work by transferring heat between the indoors and outdoors. However, during colder temperatures, frost and ice can accumulate on the outdoor unit of a heat pump. This accumulation can hinder the heat exchange process and reduce the efficiency of the heat pump.
To combat this issue, heat pumps are equipped with a defrost cycle. The defrost cycle is an automatic process that removes the frost and ice buildup from the outdoor unit, allowing the heat pump to operate at its optimal level. By periodically melting the ice, the defrost cycle ensures that the heat pump can continue to extract heat from the outdoor air and transfer it indoors, maintaining a comfortable temperature.
Defrost cycles are necessary for heat pumps due to the nature of their operation in cold weather. When the outdoor temperature drops, the heat pump extracts heat from the ambient air. However, the process of heat transfer can cause moisture in the air to condense and freeze on the outdoor unit. This frost buildup can hinder the heat pump’s ability to transfer heat effectively, leading to decreased efficiency and potential damage to the unit.
The defrost cycle addresses this issue by reversing the heat pump’s operation temporarily. During the defrost cycle, the heat pump switches into a cooling mode, allowing the outdoor coil to warm up and melt the accumulated frost. Once the frost is melted, the heat pump resumes its normal heating operation.
In addition to removing frost buildup, the defrost cycle also helps to prevent ice dams from forming on the outdoor unit. Ice dams can restrict airflow and cause further efficiency issues for the heat pump. By regularly activating the defrost cycle, heat pumps can ensure optimal performance even in cold weather conditions.
Understanding the importance of the defrost cycle is crucial for maximizing the efficiency and longevity of your heat pump. By properly maintaining your heat pump and being aware of the signs of a defrost cycle, you can ensure that your heat pump continues to provide reliable heating and cooling throughout the year.
To understand the importance of defrost cycles in heat pumps, it’s essential to explore how these cycles operate. Let’s delve into the role of the defrost cycle and the components and operation involved.
During colder temperatures, heat pumps can experience frost or ice buildup on their outdoor coils. This accumulation inhibits the heat exchange process, reducing the efficiency of the heat pump. To overcome this challenge, heat pumps employ a defrost cycle.
The primary role of the defrost cycle is to remove the ice or frost that forms on the outdoor coils. By doing so, the heat pump can restore its optimal performance and maintain efficient heating or cooling. The defrost cycle is triggered automatically based on various factors such as outdoor temperature, humidity levels, and frost accumulation.
The defrost cycle involves several key components that work together to remove the ice or frost from the outdoor coils. These components include:
Defrost Control Board: This control board is responsible for monitoring and initiating the defrost cycle. It uses sensors to detect frost buildup and activates the cycle when necessary.
Reversing Valve: The reversing valve is a crucial part of the defrost cycle. It reverses the flow of refrigerant, redirecting it to the outdoor coils instead of the indoor coils. This allows the hot refrigerant to melt the ice or frost on the coils.
Electric Resistance Heater: In some heat pumps, an electric resistance heater is activated during the defrost cycle. This supplemental heat source helps accelerate the melting process by providing additional warmth to the outdoor coils.
Defrost Thermostat: The defrost thermostat monitors the temperature of the outdoor coils. It ensures that the defrost cycle continues until the coils are completely free of ice or frost. Once the desired temperature is reached, the defrost cycle ends, and the heat pump resumes normal operation.
During the defrost cycle, the heat pump temporarily switches to cooling mode, redirecting the warm refrigerant to the outdoor coils. This causes the ice or frost to melt and drain away, restoring the heat pump’s efficiency. Once the defrost cycle is complete, the heat pump switches back to heating mode, providing comfortable temperatures indoors.
Understanding how defrost cycles work is essential for maximizing the performance and efficiency of heat pumps. Regular maintenance and proper installation are crucial to ensure that the defrost cycle functions optimally. For more information on heat pump maintenance, check out our article on heat pump maintenance.
In the next section, we will explore the common signs of a defrost cycle in heat pumps, which can help you identify if your heat pump is operating effectively.
When your heat pump enters a defrost cycle, there are several common signs that may indicate its operation. These signs can help you identify when your heat pump is undergoing a defrost cycle and ensure that it is functioning properly. The two main categories of indicators are visual indicators and audible indicators.
Steam or Vapor: During a defrost cycle, you may notice steam or vapor rising from the outdoor unit of your heat pump. This is a visual sign that the heat pump is actively defrosting and removing ice buildup from the outdoor coils.
Water Dripping: As the ice melts during the defrost cycle, you may observe water dripping from the outdoor unit. This is a result of the ice turning into water and draining away.
Fan Paused: The fan on the outdoor unit may pause or temporarily stop spinning during a defrost cycle. This is normal and allows the heat pump to direct heat to the outdoor coils and melt the ice.
Hissing Sound: If you listen closely, you may hear a hissing sound coming from the outdoor unit during a defrost cycle. This sound is caused by the refrigerant reversing its flow to warm up the outdoor coils and melt the ice.
Clicking or Clunking Noise: Some heat pumps may produce a clicking or clunking noise when transitioning into or out of a defrost cycle. This noise is typically associated with the reversing valve shifting position.
Quiet Operation: While the heat pump is in defrost mode, you may notice that it operates more quietly than usual. This is because the outdoor fan is paused, reducing noise levels during the defrost cycle.
It’s important to note that the frequency and duration of defrost cycles can vary depending on factors such as outdoor temperature, humidity levels, and frost accumulation. If you observe excessive or prolonged defrost cycles, it may indicate an issue with your heat pump that requires professional attention. Regular maintenance, such as cleaning the outdoor coils and checking refrigerant levels, can help optimize the performance of your heat pump and minimize the need for frequent defrost cycles.
Several factors come into play when it comes to the operation of heat pump defrost cycles. Understanding these factors is crucial to ensure optimal performance and efficiency of your heat pump. The three main factors affecting defrost cycles are outdoor temperature, humidity levels, and frost accumulation.
The outdoor temperature has a significant impact on the frequency and duration of defrost cycles. As the temperature drops, moisture in the air can condense and freeze on the heat pump’s outdoor coil. This frost buildup restricts airflow and reduces the heat pump’s ability to efficiently transfer heat. To counteract this, the heat pump initiates a defrost cycle to melt the frost and restore proper operation.
The defrost cycle is triggered by a temperature sensor that detects when the outdoor coil reaches a certain threshold, typically around 32°F (0°C). When the sensor detects frost, the heat pump temporarily switches to cooling mode or reverses the refrigerant flow to warm up the outdoor coil. This melting process allows the heat pump to remove the accumulated frost and resume normal operation.
Humidity levels also play a role in the occurrence of defrost cycles. Higher humidity levels increase the likelihood of frost formation on the outdoor coil, even at slightly higher temperatures. This is because moisture in the air condenses on the cold coil surface, leading to frost accumulation.
In regions with high humidity, heat pumps may experience more frequent defrost cycles compared to drier areas. It’s important to note that excessive humidity can exacerbate frost accumulation, potentially affecting the heat pump’s efficiency. Proper humidity control within your home can help reduce the occurrence of excessive frost buildup on the outdoor coil.
Frost accumulation on the outdoor coil is a natural occurrence during colder weather conditions. However, excessive frost buildup can negatively impact the heat pump’s performance. When frost accumulates, it acts as an insulating layer, preventing the efficient transfer of heat between the refrigerant and the outdoor air.
To ensure optimal performance, it’s important to monitor and address any excessive frost accumulation. Regularly inspecting the outdoor coil and removing any visible frost or ice can help maintain the heat pump’s efficiency. If you notice persistent or significant frost buildup, it may indicate an underlying issue that requires professional attention.
Understanding the factors affecting defrost cycles is essential for maintaining the proper operation of your heat pump.

The mechanism of action of bariatric surgery has evolved over the past three decades. Since the evolution of bariatric procedures, they have been classified into restrictive and malabsorptive, delineating the mechanism they worked through: decreasing the amount of food and calories one could eat, or in the latter, one could absorb, or a combination of both. This stemmed from the notion that obesity is caused by excess consumption of calories without burning the excess off, resulting in storage of the excess in the form of fat. It is actually quite surprising that this definition exists to this date, as this definition has evolved and bariatric surgery played an integral role in the understanding of the complexity of obesity as a disease, as discussed below. Still, the initial design of the procedures revolved around decreasing the intake of food or decreasing its absorption. Though the malabsorptive effects of earlier procedures were obvious, decreased caloric intake and malabsorption of fat, Halmi et al. in 1980 managed to study the positive emotional side of bariatric surgery (gastric bypass and jejuno‐ileal bypass [JIB]) versus dieting patients. They showed a vast change in bariatric surgery patients from chaotic excessive food intake to ‘normalisation’ of eating patterns, decreased snacking and binge eating, with increased ability to voluntarily stop eating without any added effort as opposed to dieting patients. All these findings to them suggested that bariatric surgery produced weight loss through ‘major changes in the biology of the obese person’. They stopped to ask the question as how both a more restrictive and a more malabsorptive produce the same satiety effect, proposing that JIB effects were humoral and gastric bypass effects were anatomical. The humoral known effects back then were attributed to increased levels of enteroglucagon, which was thought to increase satiety. What is even more interesting, the authors raised the issue that these procedures may affect the ‘set point’ for weight regulation in the hypothalamus raised in other animal research at the time, as early as 1966, and in a detailed review report by Keesey in 1978. While Halmi et al. briefly mentioned anatomical effects as reason to why satiety occurs in gastric bypass, Greenstein et al. in 1994 reported that enforced behaviour modification was the reason for weight loss, and patients ate less to avoid vomiting in gastric restrictive procedures. They documented the stark comparison between patients on diet versus vertical banded gastroplasty (VBG). Surgical patients had significantly less hunger, more will power to stop eating, and the main reasons documented were the feeling of discomfort after meals with fear of vomiting, suggesting the restriction of the pouch as the mechanism for this behaviour change. Nevertheless, with time, plenty of unknowns were unveiled. Although still relied on the concept of reduction of calorie intake, in 1995, Pories et al. in their landmark ‘Who would have thought it?’ paper reported the outcomes of Roux‐en‐Y gastric bypass (RYGB) series in 608 patients, and noted that in patients with diabetes or impaired glucose tolerance (IGT) (298 patients [49%]), euglycemia occurred prior to any significant weight loss, and any therapy for hyperglycaemia was usually discontinued at within one week of the operation. Euglycemia continued in 91% of patients, while 9% remained hyperglycemic. When analysing causes for persistence of their hyperglycaemia, the breakdown of the staple line of the non‐divided gastric pouch, with the restoration of normal passage of food, was seen in 37% of patients who did not improve, while the rest were older and had diabetes for a longer period of time. They hypothesised that bypassing the hormonally active antrum, duodenum and proximal jejunum, presenting undigested food to mid‐jejunum, with delay in the transit of food from the small pouch to the small intestine, may all play a role in mechanism of action of gastric bypass in achieving euglycemia, on top of calorie and carbohydrate reduction. When matching six of RYGB patients with a stable weight at least two years after the procedure to six matched controls, Hickey et al. reported, in 1998, less leptin hormone levels overall per unit of fat mass and higher insulin sensitivity in surgical group as opposed to controls, thus excluding weight loss as a variable in the explanation of how euglycemia is achieved and maintained after gastric bypass, and stressing the potential role of the bypassed foregut in euglycemia, and connected it to incretin hormone release from ingesting oral glucose, mainly glucagon‐like peptide 1 (GLP‐1), which is expressed distally (large bowel and ileum), and gastric inhibitory peptide (GIP), which is expressed proximally in duodenum and jejunum theoretically without actual measurement of these hormones. Cummings et al. followed in 2002 with measuring 24‐hour ghrelin hormone profile in RYGB participants, diet‐induced weight‐loss participants with matched controls with obesity and normal weight group. With better weight loss in surgical group at 36% excess body mass loss, compared to 17.4% in diet group, and 17% in obesity controls, the ghrelin hormone levels were much reduced in the surgical group (3.5 times lower than obesity controls) as opposed to increased levels in diet‐induced weight‐loss group at six months after weight loss, compared to before weight loss. Moreover, ghrelin hormone pattern lost the diurnal variation and meal‐related change in surgical group compared to other groups. This study confirmed that adaptive mechanism of ghrelin induced hyperphagia after diet‐induced weight loss, limits the amount of weight lost through diet. In addition, it introduced the concept that ghrelin suppression may play a role in weight reduction and satiety after gastric bypass beyond the effects of a restrictive gastric pouch (Figure 14.1). Le Roux et al. followed, in 2006, the comparison of lean or obesity‐matched controls, with patients who underwent RYGB and gastric banding 6–36 months prior to the study. They measured peptide YY (PYY), GLP‐1, pancreatic polypeptide (PP) and ghrelin before meals and postprandial at an interval of 30 minutes up to 3 hours, together with assessing insulin response and glucose levels. Insulin level pronouncedly peaked in RYGB patients early after meals, corresponding to early increase in both GLP‐1 and PYY, in comparison to lower levels in lean controls, and even lower in obesity controls and gastric banding patients. Ghrelin levels were lowest in RYGB, but no statistical significance was found compared to gastric banding or obesity controls, and were highest in lean controls. Authors also investigated PYY effect on rodent rats’ food intake, which increased when PYY was blocked with neutralising antibody in bypass rats, while decreased in sham rats with exogenous PYY administration. These findings suggested that PYY and GLP‐1 had the highest effect on weight loss, satiety and glycemic control after RYGB. PP release was similar amongst all groups (Figure 14.2). All the above findings steered the bariatric community into a newer direction of further research and acknowledging more powerful mechanisms of bariatric procedures than restriction and malabsorption. American Society of Bariatric Surgery (ASBS) became American Society of Metabolic and Bariatric Surgery (ASMBS) in 2007, while International Federation for the Surgery of Obesity (IFSO) added ‘and metabolic disorders’ at the end of its name. More research continued to correlate the science of gut hormones to satiety, weight loss and metabolic improvements. But, what was the role of calorie restriction? Lips et al. studied five groups: very low‐calorie diet (VLCD) with DM, RYGB with DM, gastric banding with impaired glucose tolerance (IGT), RYGB with IGT and normal weight controls. All groups received an oral glucose tolerance test before and two to three weeks after intervention (surgery or diet initiation). Several blood draws were taken over three hours after drinking a high‐calorie drink for GIP, GLP‐1, PYY and ghrelin together with insulin and glucose levels. To everyone’s surprise given the previous data, RYGB did not improve glucose metabolism any more than VLCD did in patient with DM. RYGB did cause gut hormone alterations that were observed previously: increased GIP, GLP‐1 and PYY, decreased ghrelin with enhanced insulin response (marked increase in postprandial insulin compared to VLCD or banding), but the reduction of fasting and postprandial glucose levels were equivalent to VLCD, suggesting that caloric restriction and reduction was the reason for early improvement in glucose homeostasis. In fact, HOMA‐ir was reduced more in VLCD in comparison to RYGB in that study, raising more questions about the gut hormones known on the impact of glucose homeostasis (Figure 14.3). Fast forward to today and we now have more knowledge of additional gut hormones that influence the changes seen after various bariatric procedures. Neilson et al. compared the hormonal response in patients undergoing RYGB and sleeve gastrectomy (SG) with mandatory pre‐operative 8% weight loss prior to both interventions. They studied glicentin and oxyntomodulin, recently discovered gut hormones, which are co‐secreted from L‐cells together with GLP‐1 and have longer half‐lives than GLP‐1. They correlated hormone basal and postprandial levels with variations in weight loss and appetite, especially energy‐dense foods. They reported higher glicentin, oxyntomodulin, GLP‐1 and PYY levels in RYGB as opposed to SG, while SG had lower more suppressed ghrelin level. Of note, ghrelin increased in both groups pre‐operatively with mandatory pre‐operative weight loss, confirming the effects of diet on increasing its level. Ghrelin level remained at the same elevated pre‐operative level post‐operatively in RYGB, while decreased in comparison in SG. Basal levels of glicentin and oxyntomodulin, on the other hand, increased only after RYGB, while basal GLP‐1 and PYY levels did not increase in RYGB or SG. This basal increase at 6 months, predicted successful weight loss in patients at 18 months’ follow‐up. It also was associated with decrease energy‐dense food intake as opposed to other hormones. Authors estimated that both had direct effects on weight loss accounting for 62–64%, while 36–38% was weight loss due to their effects on decreasing high‐energy food intake. Postprandially, only GLP‐1 increased in both RYGB and SG, with higher increase in RYGB. Meanwhile, PYY, glicentin and oxyntomodulin increased postprandially only in RYGB, while remaining same in SG. Ghrelin remained reduced in both, more so in SG. Combining the analysis of all five hormones at 3 and 6 months, the authors were able to predict 60% of the variability in weight‐loss patterns at 18 months. They established a synergistic effect of these hormones on weight loss and suggested using these levels early to be able to predict patients who will need more guidance to achieve better results. Only glicentin and oxyntomodulin basal and postprandial increases correlated with both higher weight loss and decreased high‐energy food intake. Other hormones had no impact on food intake in this study. These changes also could explain the difference in better weight loss and potentially better metabolic control of diseases in RYGB compared to SG. We also know that biliopancreatic limb (BPL) lengths affect the outcome of weight loss and metabolic control through changes in gut hormone. Patrício et al. studied hormonal changes in 60–90 cm versus 200 cm BPL with a constant Roux limb length in RYGB. They did not measure glicentin or oxyntomodulin. However, they reported a significant increase in fasting basal GLP‐1 and another hormone, neurotensin, levels in longer BPL. These were also higher after a mixed meal test. Neurotensin is another hormone that is co‐secreted with GLP‐1 and PYY from L‐cells in response to fat, and bile salts in particular. It plays an important role in anorexia and decreasing food intake. Other hormones, PYY, glucagon, GIP and PP, were not significantly different. PYY was higher postprandially, while GIP was lower in longer BPL but without statistical significance. Of note, while glucose levels were similar in both groups, insulin levels were lower, suggesting a better, more efficient metabolic process generated by the longer BPL. All these studies suggest that we are only scratching the surface of the important changes and mechanisms that occur after bariatric surgery that potentially solve the mystery of obesity. Below we summarise each gut hormone, its action, source and the changes that occur in patients with obesity at baseline, with dieting and after various bariatric procedures (Table 14.1: gut hormones and effects: Representing table 1 in Pucci and Batterham (2000) with modifications). In 1990, Boozer et al. reported that ileal transposition in mice not only produced weight loss but also attenuated any weight gain by high fat diet in comparison to sham rats. Although the mechanisms are still unclear until now, we now know that bariatric surgery significantly alters the bile acid levels in the enterohepatic circulation.

A novel method for directly testing the adhesion strength of three lead-free solders was developed and compared with conventional methods. The Isotraction Bump Pull method utilizes a combination of favorable qualities of the Cold and Hot Bump Pull tests. Solder bumps were generated onto copper printed circuit board substrates using an in-house-fabricated solder bump-on-demand generator. The method uses polymer epoxy to encapsulate solder bumps under uniform tractions, and tested under tension for pull-off stresses. Maximum pull-off stresses for the novel method are: 18MPa (Sn-3.5Ag), 16MPa (SAC 305) and 22MPa (Sn-0.7Cu) and fall at the low end in the literature comparisons. It is suggested that since the copper substrates used in the current work were untreated, that the lower pull-off stress values resulted. Energy Dispersive X-Ray Spectrometry of the newly created faces after fracture shows that brittle fracture of the Intermetallic Compound layer was the mode of failure.

In years past, tin-lead alloys were used to solder together electrical components. However, health concerns arose from issues surrounding the use and disposal of heavy metals such as lead. After the passing of the Lead Exposure Reduction Act in 1993 in the U.S., and the European Union’s ban of lead in electronics taking effect in 2006, suitable alternatives for tin-lead solders have been pursued . Extensive studies exist of the material properties of lead-free (LF) solders and their fluxes [2-11]. As use of LF solders increases worldwide, the need to create, test, and validate the properties of these solder alloys also has risen.
The requirements of LF solders are much the same as traditional leaded solders; they must have similar melting temperatures, strength and durability, ductility, thermal fatigue resistance, electrical resistance, should use the same manufacturing processes wherever possible, and allow for the continued miniaturization of the electronics industry.
Numerous studies into the mechanical and thermal behavior of these alloys have been conducted in the past few decades, making it possible for the development of industry standards and best practice methods to become available [12-15]. Some of these are the drop impact test, bending test, hot bump pull (HBP), and the cold bump pull (CBP) testing methods.
As the Intermetallic Compound (IMC) layer is known to be the weak location of most soldered joints due to its brittle nature, it is of specific importance to be able to study and quantify the mechanical properties and behavior of IMCs for different LF solders. Taking a focused look into two of the more popular direct solder bump testing methods HBP and CBP, some issues become clear with the study of IMC layers.
Through the insertion of the pin for the HBP method, the solder bumps undergo a large degree of structural change, where both the micro and macro structure of the bump is altered. The addition of the pin also generates a secondary IMC and can cause the characteristics of the first IMC to change due to the reflow that occurs during the insertion process. Despite the CBP method alleviating the need to heat the solder, the clamping process used to gain a mechanical grip upon the exterior of the bump can cause irreversible, plastic deformation to the bump. This deformation has been shown to cause a bias towards brittle fracture and so the associated variables to the process must be optimized through a trial and error process . The added issue to this is then that whenever a new solder, bump size or gripping system is used the variables that were previously optimized can once again become suspect. In order to overcome the issues associated with the HBP and CBP testing methods, and yet still combine their respective positive features while maintaining a direct tensile testing method of solder bumps, a novel method was developed and evaluated: the Isotraction Bump Pull (IBP).
By combining the basic methods of the HBP and CBP testing, it becomes possible to pool positive attributes from both methods. This IBP method, schematically shown in Figure 1, uses a stainless steel screw to replace the hot metal pin of the HBP. However, the pin is not inserted into the bump; rather the screw and bump are encapsulated in a stiff epoxy that is used to transfer the pulling force from the vertical load system to apply uniform tractions over the entire bump surface. This exterior support of the bump resembles the method of the CBP, however there is no need to plastically deform the solder bumps prior to testing to achieve a mechanical grip, as the cast epoxy conforms to the contours of the bump and creates a uniformly secure grip. This lack of plastic deformation of the bump prior to testing not only removes the independent variables associated with the tweezers and clamping process of the CBP, but also does not create the micro-cracks associated with CBP that both weaken the bumps and can cause a bias towards brittle fracture.
Figure 1:Isotraction Bump Pull (IBP) diagram (a) Assembly (b) Testing.
In order to allow for this method to be used on existing equipment commonly in practice for the HBP and CBP, a pulling speed of 0.3mm/s was used. Additionally, the printed circuit board (PCB) substrates used in this study were held in place from the beginning of the test and not allowed a ramp-up run to reach the set speed of the system.
The bumps in this study were generated from three types of LF solder to evaluate the method’s universal application, namely Sn- 3.5Ag, Sn-3.0Ag-0.5Cu, and Sn-0.7Cu, referred to hereafter as SnAg, SAC305 and SnCu, and were created using a bump-on-demand generator, as seen in Figure 2. The generator was designed based on the works of several authors in the literature with slight alterations [17-20]. By changing the magnitude and duration of pressure pulses of nitrogen gas used to generate each bump, the size of the solder bumps could be increased or decreased as desired without any mechanical changes to the system. Also, the bumps for the Sn-3.5Ag alloy were generated first, to eliminate any cross-contamination of these bumps with the copper contained in the other two solder alloys. The bumps had an average mass of 150mg, ±20mg.
Figure 2:Bump on demand generator.
In order to cast the epoxy around the solder bumps and encapsulate both the solder and stainless steel screws, a custom epoxy molding form was designed and fabricated. This system, shown in Figure 3, was composed of an aluminum base plate used to position six individual PCB substrates with the corresponding bumps into the middle of circular Teflon (PTFE) molds, cut from tubular sections of pipe with an outside diameter of 25.4mm and an inside diameter of 12.7mm.
Figure 3:Epoxy casting assembly (a) Assembled (b) Disassembled.
To allow for the mold forms to be removed after casting, the tube sections were cut in half vertically. There were no cleaning processes, deoxidizing or fluxing processes used on the copper substrates. Each substrate was positioned in the machined base plate of the casting mold. The Teflon forms were positioned around the individual bumps and PVC sheets with machined corresponding notches to the forms were bolted onto the bottom plate. A top plate of transparent polycarbonate plastic was used to allow visual inspection of the interior of the casting molds. A throughhole was made in this top plate at the corresponding center positions of each of the six casing forms. These holes allowed for the positioning of the stainless steel screws that would function as the pins for the tensile tests. The mold casting components were assembled with the PCBs and bumps, forms, and pressure plates. Then two-part epoxy (JB Weld, Sulphur Springs, TX) was cast into the forms individually. Immediately after the epoxy was cast, the top plate was used to position the stainless steel screws in place and ensure that the forms were fully seated on the face of the PCB substrates. The system was put under pressure using through bolts from the bottom aluminum to the top polycarbonate plates and the epoxy was allowed to cure for 18 hours, per the manufacturer’s recommendations. At the completion of this process, shown in Figure 4, the samples were removed from the molds and were labeled according to their alloy type.
Figure 4:Solder bump tensile testing samples.
In order to load the samples to fracture using a high precision universal vertical load machine (Instron, model 3345, Norwood, MA), a set of custom fixtures was fabricated to grip the PCB and stainless steel screw of each testing sample. These fixtures, shown in Figure 5, contained a top assembly with a tapped hole at the center of the bottom face to hold the screw securely in place during testing, and a bottom assembly composed of two parallel steel plates, bolted together with a gap twice the height of the PCB substrate thickness. Additionally, the top plate had a center through-hole which allowed the epoxy casting to pass through, while holding the PCB in place.
Figure 5:Upper and lower fixture assemblies with tensile sample.
Each of the three LF solder alloys was tested using the tensile assembly. The results were recorded using the integrated software to the Instron system as the displacement and load to failure of each sample. An example result of this can be seen in Figure 6 where newly exposed faces of both the PCB and bump contain an area corresponding to the fractured IMC.
Figure 6:Newly exposed faces of example fractured sample.
To convert the load values to stresses to allow for comparison to stress values for other solders found in the literature, the areas of the newly exposed fractured surface of the IMC was used, an example of which is shown at the center of the PCB square in Figure 6.
There are two types of plot forms in the results, samples of which are shown in Figure 7. The first is an example of a successful test result (solid curve), while the other is a failure of the epoxy, resulting in an unsuccessful test (dashed curve). The failure occurred due to air pockets within the epoxy forming voids around the interface of the bump and epoxy. These voids weaken the epoxy surrounding the solder to the point that when the load reaches a critical value, these voids decreased the overall strength of the epoxy to the extent that it could not perform its task of remaining adhered to the bump. All unsuccessfully tested samples contained at least one such void, and account for 5 out of the 84 tests conducted for the three solder types, or 5.9% of the total testing group. The remaining 94.1% of the tests concluded in brittle fracture of the IMC
Figure 7:Tensile test result types.
At the conclusion of the tensile tests, the median and mean peak stress values for each of the successful tensile tests were analyzed. Box plots of the successful tests for each solder are shown in Figure 8. The raw data for each solder was normally distributed and the mean and median peak values for each solder were calculated within one standard deviation of the mean of each original data set. The median peak pull-off stress values at failure are 13.9MPa, 5.9MPa, and 20.1MPa, for the SnAg, SAC305 and SnCu solders, respectively. The mean pull-off stress values for each solder is shown with a diamond shape within each box, with the standard deviation marked by the vertical whisker lines which terminate at their maximum and minimum values. For each solder, the first and third quartiles of the peak stress results are represented by the portion below the median value and the portion above the median value, respectively, in each box. The first quartile represents the median values of the lower 50% of the data set, and the third quartile represents the median values of the upper 50% of the data set. It is through this graphical representation that one may identify the true behavior of the solders when compared to one another. By using the box plots to examine the median pull-off stress values, it is clear that the two bi-metallic alloys performed with higher mean peak pull-off stress values, and of those two, SnCu is the leading alloy. In addition to the mean and median peak pull-off stress values for the SAC305 solder being lower than the two other solders tests, it also has the largest deviation within the data, while the SnCu solder has both the highest mean and median values and the lowest deviation within the data.
Comparisons of the maximum pull-off stress values for the IBP method were made with those found in the literature. In Figure 9, the solid (red) circles represent the IBP maximum pull-off stress values for each of the LF solders and are compared with maximum pull-off stress values for CBP and HBP methods of the same solder types. The reflow temperatures, pull speeds and surface finishes used for the literature values, when noted in the respective papers, are included in Table 1.
Figure 8:Box plots of pull-off stress values.
Table 1: Literature comparison information.
The maximum pull-off stresses for the IBP method fall at the low end of the pull-off stress values found in the literature when compared with both the CBP and HBP methods for all three LF solder types. The IBP values are: 18MPa (SnAg), 16MPa (SAC305) and 22MPa (SnCu). The majority of the comparisons found were those for the SnAg solder, which generally had the lowest pull-off stress values of the three solders. In addition for SnAg, all three methods IBP, CBP and HBP, have pull-off stress values on the same order of magnitude, ranging between 15 and 88MPa. The only method found to have a lower pull-off stress than IBP was CBP at 15MPa for the SnAg. Of the comparisons of CBP and HBP for SAC 305 and SnCu, all of the pull-off stress values were an order of magnitude greater than the IBP values. It is suggested that since the copper substrates used in the current IBP work were untreated, that the lower pull-off stress values resulted.
In addition to the tensile tests that were performed on the bump samples, a scanning electron microscope (SEM) (JEOL JSM- 5900LV, JEOL USA Inc, Peabody, MA) was used to perform high magnification of the fracture surfaces to verify that brittle fracture occurred. Examination of the high magnification images in Figure 10, show brittle fracture for the newly exposed faces of the PCB and bump.
Figure 9:Comparison of Maximum Pull-off Stress for IBP method with CBP and HBP methods from literature.
Figure 10:High magnification of SnAg surfaces (a) on PCB face (b) on bump face.
Lastly, in addition to the images of each newly formed surface, the SEM was used to perform Energy Dispersive X-Ray Spectrometry (EDS) to analyze the surface chemistry of both newly exposed faces. Shown in Figure 11a-11d, where Figure 11c corresponds to the boxed location in Figure 11a, and Figure 11d corresponds to the boxed location in Figure 11b, the values of Sn and Ag are nearly identical. Of special note, is that the levels of Cu are also nearly identical for the two positions. This is especially important as the solder in question was SnAg with no Cu present in the mix and this was the first solder tested in the stainless steel crucible, and so no Cu contributed to the solder prior to the formation of the joint. The presence of Cu then shows that material from the substrate was absorbed into the solder and formed the IMC. Additionally, as the same materials are present in roughly the same concentrations on both faces, this shows that the brittle fracture that was identified from the images was through the IMC and not at an interface of the IMC and either the solder or the Cu substrate[21-23].
By combining the positive attributes of both the HBP and CBP direct tensile testing methods, it was possible to develop a novel method for tensile testing the adhesion strength of lead-free solders. The Isotraction Bump Pull (IBP) method and subsequent analyses were able to show the following:
A. That the IBP method conforms to the requirements of the HBP and CBP methods while not adversely impacting the structure of the solder bumps prior to testing;
B. That the results for the IBP method for the Sn-3.5Ag solder falls within the pull-off stress values when compared with CBP and HBP methods in the literature, and is an order of magnitude lower in pull-off stress values when compared with the mechanical behavior of SAC 305 and Sn-0.7 Cu solders using the CBP and HBP methods;
C. That the method identifies the failure mode as that of brittle fracture of the IMC layer.

Boosting your protein intake can assist in weight loss by influencing certain hormones, which helps you stay fuller for longer and offers additional advantages.
Protein is a crucial nutrient for losing weight and improving your physique.
Eating more protein can increase your metabolism, curb your appetite, and alter various hormones that regulate weight.
Protein aids in reducing both overall weight and belly fat through several mechanisms.
This article gives an in-depth analysis of protein’s role in weight loss.
Protein alters several hormones that regulate weight
The brain, especially a part called the hypothalamus, actively controls your weight.
Your brain decides when and how much to eat by interpreting various types of information.
Hormonal changes in response to eating are crucial signals for the brain.
Increasing your protein intake can raise the levels of satiety hormones like GLP-1, peptide YY, and cholecystokinin, while decreasing levels of the hunger hormone ghrelin.
By substituting protein for carbs and fats, you lower the hunger hormone and increase several satiety hormones.
This significantly reduces hunger, which is a primary way protein aids in weight loss. It naturally leads you to consume fewer calories.
Summary: Protein reduces the hunger hormone ghrelin and increases satiety hormones like GLP-1, peptide YY, and cholecystokinin, leading to a natural decrease in calorie consumption.
The body expends calories digesting and metabolizing protein
After eating, some calories are utilized to digest and metabolize the food.
This process is known as the thermic effect of food (TEF).
While there’s some debate over the exact numbers, it’s clear that protein has a much higher thermic effect (20-30%) than carbs (5-10%) or fats (0-3%).
Taking a 30% thermic effect for protein as an example, it means that out of 100 calories of protein consumed, only 70 calories are effectively used.
Summary: Around 20-30% of calories from protein are spent during the digestion and metabolism of the protein.
Protein increases calorie burning
The high thermic effect of protein, along with other factors, typically boosts your metabolism.
This results in higher calorie burning throughout the day, even while you’re asleep.
Studies have shown that a diet rich in protein can increase daily calorie burn by about 80 to 100 calories.
This effect is even more pronounced when you consume more calories than your body needs. For instance, one study found that a high protein diet during a period of overeating led to an extra 260 calories burned each day.
So, diets high in protein not only help you burn more calories but also have a “metabolic advantage” compared to diets lower in protein.
Summary: Consuming more protein can increase your daily calorie burn, ranging from 80-100 extra calories to 260 calories during periods of overeating.
Protein decreases hunger, leading to fewer calories consumed
Protein can significantly diminish hunger and appetite through various mechanisms.
This often results in a natural reduction in calorie intake.
This means that you tend to eat fewer calories without needing to consciously control portions or count calories.
Numerous studies indicate that increasing protein intake leads to consuming fewer calories.
This effect is seen both over a single meal and over sustained periods, as long as the high protein intake is maintained.
For instance, in one study, participants consumed 441 fewer calories per day when protein made up 30% of their diet.
Therefore, diets high in protein not only have a metabolic benefit but also an “appetite advantage,” making it much easier to cut calories compared to diets with lower protein content.

Summary: Diets rich in protein can significantly curb hunger and appetite, making it much easier to consume fewer calories, compared to lower protein diets.
Protein reduces cravings and lessens late-night snacking
Cravings can be a major hurdle for dieters and are often a reason why people struggle with diets.
Late-night snacking is another significant challenge, especially for those prone to weight gain, as these extra calories add to their total daily intake.
However, protein can significantly impact cravings and the urge to snack late at night.
One study comparing high-protein and normal-protein diets in overweight men found that a diet where protein made up 25% of the calories reduced cravings by 60% and decreased the desire for late-night snacking by half.
The first meal of the day might be particularly important for protein intake. A study among teenage girls showed that a high-protein breakfast notably diminished cravings.
Summary: Increasing your protein intake can lead to a significant reduction in cravings and the desire to snack late at night, contributing to a healthier diet adherence.
Protein aids in weight loss without strict dieting
Protein influences both aspects of the “calories in vs calories out” balance. It reduces calorie intake and increases calorie expenditure.
That’s why it’s not surprising that high-protein diets lead to weight loss, even without intentional restrictions on calories, portion sizes, fats, or carbohydrates.
In a study with 19 overweight individuals, increasing protein to 30% of their total calorie intake led to a significant decrease in overall calorie consumption.
Participants in this study lost an average of 11 pounds over 12 weeks, simply by adding more protein to their diet without consciously restricting other nutrients.
While results vary, most research confirms that high-protein diets can result in notable weight loss.

Higher protein intake is also linked to reduced belly fat, the harmful type that accumulates around organs and can lead to health issues.
However, the key is not just losing weight, but maintaining that loss over the long term.
Many people can diet temporarily and lose weight, but often they regain the weight later.
Interestingly, increasing protein intake can help prevent this weight regain. One study showed that a slight increase in protein intake (from 15% to 18% of total calories) halved the weight regain after a diet.
So, protein doesn’t just help with losing weight; it can also help keep it off in the long term.
Summary: A diet high in protein can lead to weight loss, even without strict calorie counting, portion control, or carb restriction. Slightly increasing protein intake can also help prevent weight regain.
Protein protects muscle mass and prevents metabolic slowdown during weight loss
Losing weight doesn’t always mean losing fat exclusively.
Often, muscle mass decreases during weight loss, too.
But ideally, you want to lose body fat, both the subcutaneous fat (beneath the skin) and visceral fat (around the organs).
Muscle loss is an unwanted side effect of weight loss for many.
Another common issue during weight loss is a reduction in metabolic rate, meaning you burn fewer calories than before losing weight.
This phenomenon is sometimes called “starvation mode,” leading to a significant drop in daily calorie expenditure.
Consuming adequate protein can help minimize muscle loss, maintaining a higher metabolic rate as you lose body fat.
Strength training is also crucial in reducing muscle loss and preventing metabolic slowdown during weight loss.
Hence, a high protein intake combined with rigorous strength training are essential components of an effective fat loss plan.
These strategies not only maintain a robust metabolism but also ensure that the body beneath the fat looks toned and lean. Without sufficient protein and strength training, there’s a risk of appearing “skinny-fat” rather than fit and muscular.
Summary: Consuming enough protein can help prevent muscle loss during weight loss and maintain a higher metabolic rate, especially when coupled with intensive strength training.
Determining the optimal amount of protein
The standard dietary reference intake suggests 46 grams of protein per day for the average woman and 56 grams for the average man. While this may prevent deficiency, it’s not the ideal quantity for those aiming to lose weight or build muscle.

Research linking protein to weight loss typically expresses protein intake as a percentage of total calories. Aiming for protein to constitute 30% of your calorie intake appears highly effective for weight loss.
To calculate protein in grams, multiply your calorie intake by 0.075. For instance, on a 2000 calorie diet, you’d aim for 2000 * 0.075 = 150 grams of protein.
Alternatively, you can target protein intake based on your body weight, with common recommendations suggesting 0.7-1 gram of protein per pound of lean mass (1.5 – 2.2 grams per kilogram).
It’s beneficial to distribute your protein intake throughout the day, incorporating it into every meal.
While precision isn’t crucial, maintaining a range of 25-35% of your total calories from protein should be effective.
For more insights, refer to this article:
Summary: For weight loss, aiming for 25-35% of your total calories from protein may be optimal. On a 2000 calorie diet, this equates to about 150 grams of protein.
Boosting your protein intake
To increase your protein consumption, simply incorporate more protein-rich foods into your diet. These include:
- Meats: Chicken, turkey, lean beef, pork, etc.
- Fish: Salmon, sardines, haddock, trout, etc.
- Eggs: All types.
- Dairy: Milk, cheese, yogurt, etc.
- Legumes: Kidney beans, chickpeas, lentils, etc.
A comprehensive list of healthy, high-protein foods is available in this article:
If you’re following a low-carb diet, opt for fattier cuts of meat. Otherwise, prioritize lean meats to keep protein levels high without consuming excess calories.
Considering a protein supplement, like whey protein powder, can also be beneficial, especially if you find it challenging to meet your protein targets through food alone. Whey protein has been associated with several benefits, including enhanced weight loss.
Incorporating more protein into your diet may seem straightforward, but making it a consistent part of your nutritional plan can be challenging.
Initially, it’s advisable to use a calorie/nutrition tracker. Measure and record everything you eat to ensure you’re meeting your protein goals.
This tracking isn’t a lifelong commitment, but it’s crucial in the beginning to understand what a high-protein diet entails.
Summary: To boost your protein intake, consume a variety of high-protein foods. Initially, using a nutrition tracker can help ensure you’re meeting your protein goals.
Protein: The straightforward, enjoyable route to weight loss
Protein stands out as the ultimate nutrient for fat loss and enhancing your physique.
Increasing your protein intake doesn’t require cutting out other food groups; it’s about adding beneficial nutrients to your diet.
This approach is particularly enticing because many high-protein foods are not just nutritious but also delicious, making it a satisfying dietary addition.
Adopting a high-protein diet isn’t just a short-term fix for weight loss; it’s a viable long-term strategy for obesity prevention.
By consistently consuming more protein, you support the “calories in vs calories out” balance in your favor.
The impact on your waistline could be significant over months or even years.
However, it’s crucial to remember that overall calorie intake still matters. Protein can help reduce appetite and increase metabolism, but weight loss requires consuming fewer calories than you burn.
It’s possible to overconsume calories, offsetting the benefits of a high-protein diet, particularly if you’re eating a lot of processed foods.
Therefore, it’s advisable to base your diet on whole, single-ingredient foods.
While this article emphasizes weight loss, it’s worth noting that protein offers numerous additional health benefits. | <urn:uuid:7fe7c44b-3441-4494-9c8d-9aad2f306d9e> | CC-MAIN-2024-51 | https://feelgoodpal.com/blog/how-protein-can-help-you-lose-weight/ | 2024-12-07T23:11:15Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066433271.86/warc/CC-MAIN-20241207224914-20241208014914-00800.warc.gz | en | 0.933829 | 2,537 | 2.53125 | 3 |
Although many people consider sex to be a private matter or a personal issue, sex and sexuality are actually some of the most public and shared spaces among humanity. From reproduction, to presentation of the self, gender roles, mating, etc, sex fuels most of what people do. But there is a dark reality surrounding sex, and this reality only affects women; the reality is that female sexual liberation is not real in the public space. Female sexual liberty can exist in a personal space; you can feel completely liberated and perform in a manner that expresses this sentiment, but to the outside world you are being promiscuous and/or you are being seen as sexual object. So despite feminist scholarship and hopes for sexual equality, in the larger societal context, a woman can’t act upon her sexual desires as she wishes without being seen as a whore or a commodity, and the reasons for this that sexuality is an affect and hyper sexual women are commodified.
To be an affect is to be affected by something or someone. In her essay Happy Objects, Sara Ahmed argues that happiness is an affect. “To be made happy by this or that is to recognize that happiness starts from somewhere other than the subject who may use the word to describe the situation” (29). And just as Sara Ahmed describes the function of happiness as an “affect”, sexuality, meaning one’s capacity for sexual activity and sexual orientation/preference, functions as an affect. In an effort to unpack this claim, it is important to have a deeper understanding of what it means for something to function as an “affect”. A basic example that helps shed light on this idea is ice-cream and its relationship to society. Ice-cream, in a larger social context, is often associated with happiness, because it is usually consumed during joyful celebrations or occasions: birthdays, graduation, weddings etc. And this tradition of having ice-cream in joyful occasions or having ice-cream being associated with joyful occasions has been repeated/followed since nearly the beginning of its creation in the 16th century (international dairy foods association). Objects become happy through repetition, “we can note here the role that habit plays in arguments about happiness… the association between objects and affects is preserved through habit” (Ahmed,35). So if it is habit that is needed to create associations between objects and affects, All that is needed for anything to become associated with an affect is repeated dialogue or expressed sentiments over an extended period of time to create a habit that will lead to an affect.
This discussion of positive and negative affect relates to sexuality, because certain acts or expressions of sex can become taboo or negative: prostitution, polyamorous relationships, sodomy, etc, through society’s discourses relating to these topics. Sex is rarely a private or completely isolated experience. So in the same way we see objects being endowed with positive or negative affect, we can see sexuality being commodified into an object and being given a particular affect in the language used to describe it in a social setting: “she is a whore” or “gross, she is a prostitute”. So what determines which sexual acts are good and which are bad?
In order for something to become a happy or sad affect there needs to be repetition and habit. “Social constructionist theories have regarded human sexual desire as shaped extensively by culture and socialization, often mediated by language as an ordering principle that is shared in common with other people. These theorists emphasize cross cultural variation to argue for the cultural relativity of sexual desire… Who does what to whom sexually is regarded as a product of cultural rules and individual, linguistically mediated decisions rather than as a biological imperative” (Baumeister, 347). Since the biblical days women who are too sexually active have been labeled as whores and shunned from society. For example, in the Bible, we see the story of Mary Magdalene who is about to be stoned to death for being a prostitute. In this story you can see two things, one the presence of an already negative attitude towards overly sexually active woman, and two what will be another origin point in the long lineage of shaming overly sexually active women. The language and history surrounding sexually active woman has been so consistently negative that it has become nearly impossible to separate the legacy of a whore from a modern day “sexually liberated woman”. And this inability to separate the negative emotions or opinions from the reality of the modern day sexually active woman is so dangerous because, “[w]hen history becomes second nature, the affect becomes literal: we assume we experience delight because “it” is delightful” (Ahmed, 37) . This sheds light on as to why extremely, or even moderately sexually active women, have become imbued with a negative affect whereas the pure and pious woman is a happy object or happy experience. History has portrayed the former as happy object and thus it has literally become so because, “[w]hen history becomes second nature, the affect becomes literal…(Ahmed, 37). Whereas the later, overly sexually active women have become demonized and imbued with a negative affect. And this negative affect is further circulated through society making it nearly impossible to remove. “The circulation on objects is thus the circulation of goods. Objects are sticky because they are attributed as being good or bad, as being the cause of happiness or unhappiness. This is why the social bond is always rather sensational. Groups Cohere around a shared orientation toward somethings as being good, treating some things and not others as the cause of delight. If the same objects make us happy” (Ahmed, 35). Taking this idea of objects being sticky and attributed with being good or bad, and this good or bad attribution coming from habit or repetition, we can see how it is plausible for the repeated positive or negative expressions towards particular sexual habit can lead to a positive or negative affect being associated with that “object”. The negative history associated with overly sexually active women and the circulation of sticky objects explains why the negative affect of overly sexually active women has become so widely spread and is nearly impossible to undo.
One may argue undoing the negative affect towards overly sexually active women is possible due to recent changes in attitudes toward sex and sexuality. But I refute this argument because I believe that overly sexually active women have become commoditized. I will use the story of a famous Brazilian Prostitute by the alias of Bruna Surfhistina to prove my point.
Bruna Surfisitinha, born as Raquel Pacheco, was born in Sorocaba, Sao Paulo Brazil on October 28th 1984. Soon after her birth she was adopted into an upper middle class family. At the age of 17, she ran away from home to escape the overly traditional beliefs that her adoptive family held. And as a 17 year old girl with no money and no source of income, she began her trip down the rabbit hole that is prostitution in Brazil. However, little did Bruna know that she would soon become one of the most famous call girls/ sex symbols of 1990’s Brazilian culture. Bruna did not gain notoriety as a call girl until she published her blog, Bruna Surfhistina. On her blog, Bruna chronicled her experiences with each one of her clients in graphic detail. Her blog was an instant success and received over 50,000 reader a day. Her online success also led to her appearing in many television shows, magazines, and pornographic films in Brazil. But poor management of funds and drug addictions led to Bruna’s fall from fame and the spotlight, until 2005 when she wrote her book O Doce Veneno Do Escorpiao ( The Scorpion’s Sweet Venom). The book was an instant success selling over 30,00 copies within the first month and then being translated and published by Bloomsbury Publishing in English in 2006. And once again in 2011, Bruna and her story surged forth once more into the spotlight with the production and release of her film, Confessions of a Brazilian Call Girl. The film, produced by Rio De Janeiro’s Tv Zero and distributed by Imagen Films, was a success grossing over 12.4 million in the box office, making it the second highest local grossing film in Brazil.
Since Bruna was so successful as a prostitute, an argument could be made that her success was due to a more progressive and accepting world that believed in embracing your sexuality as you please. But I counter this argument by attributing her success to the commodification of women; Bruna was and is not sexually liberated, at least in a social context, because her sexuality became a commodity.
Bruna became part of a genealogy of objectification of women. On a daily basis people are objectified and objectify women. It is an epidemic that plagues our everyday lives. And it harms us more than we can comprehend. It has hindered our ability to see women as people and differentiate between females and objects. Research, done by Sarah Gervais and published by the European Journal of Social Psychology , states “both men and women process a woman’s body using local cognitive processing” (Gervais et al. 2012). Local cognitive processing is method we use to think about objects, and now women. In other words, we think about women and objects in the same way. But what is worse than being seen as an object? It is being seen as specific aspects of an object. Women are reduced down to their sexual body parts. A recent study proved that a “ [woman’s] sexual body parts were more easily recognized when presented in isolation than when they were presented in the context of their entire bodies”(Gervais et al. 2012). So, not only are women being objectified by the media, and society, but they are being equated to objects, and then broken down in specific aspect such as: eyes, lips, or breast. And this objectification can be linked to a theory first described my Marx as commodity fetishim.
Commodity fetishim, in short, is the distortion of actual value of an object or person by the value it is given by its exchange rate. Purdue University’s page on Marx’s theory of commodity fetishim explains this idea with an example of a carpenter and his table. “The connection to the actual hands of the laborer is severed as soon as the table is connected to money as the universal equivalent for exchange. People in a capitalist society thus begin to treat commodities as if value inhered in the objects themselves, rather than in the amount of real labor expended to produce the object” (purdue.edu). In this example we see that even if the carpenter put in thousands of hours into creating table, that labor could be diminished by giving the table a low exchange price on the market, thus taking away the natural value of the table and the work put by the carpenter. Now if we apply this same concept to the story of Bruna Surfisthina, we see that she is commotizied in the most literal and figurative senses. As a sex worker, she puts a literal price on herself when she exchanges sexual acts for money. And as a woman and prostitute, she is given a societal value, which for the average prostitute, would be a negative one equivalent to that of a whore, diminishing her value as a person in larger societal context. But it just so happens that in the case of Bruna, she was valued at a higher market value, an upper-class call girl, and therefore gets treated as an upperclass commodity, which enables her to be more palatable in larger societal context and allows her to perform as a sexually liberated woman in a social setting even though she is not. On top of this, Bruna’s race plays a role in her success, because she is able to take advantage of white privilege. According to Dr. Frances E. Kendall, a nationally acclaimed consultant who has spent over 35 years working on diversity and white privilege, white privilege is, “… an institutional (rather than personal) set of benefits granted to those of us who, by race, resemble the people who dominate the powerful positions in our institutions” (1). Bruna’s white privilege further set her apart from the average prostitute, and once again made it easier for her to be valued at a higher market price in the larger social context.
It is important to distinguish between the myth of Bruna’s sexual performance as a liberated woman from the reality of her sexuality being commoditized. It may have appeared that people loved Bruna, because she was a sexually liberated woman, but what really was going on was a celebration of a highly commodified white woman. And in my opinion, this commodification is dangerous, because it gives woman a false hope in the belief that one day they can truly be sexually liberated, when the reality is that their sexual liberation will be entangled with the commoditization of their hyper sexuality. | <urn:uuid:af510c7a-949a-4755-90bc-2fc96ca546f0> | CC-MAIN-2024-51 | https://madap.tome.press/chapter/bruna-surfistina/ | 2024-12-07T23:08:09Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066433271.86/warc/CC-MAIN-20241207224914-20241208014914-00800.warc.gz | en | 0.964882 | 2,687 | 2.5625 | 3 |
The Quran is the holy book of Islam. Muslims believe it is the exact word of God, given to Prophet Muhammad (PBUH). It is very important to the Islamic faith and how Muslims live. Knowing when and how the Quran was written helps us understand why it is so special and important. Let’s learn about the story of the Quran and how it has been kept safe.
The Revelation of the Quran
The story of the Quran starts in the year 610 CE when Prophet Muhammad (PBUH) was in a cave called Hira, near Mecca. He was meditating, which means he was thinking deeply about life and God. While he was in the cave, the angel Jibreel (Gabriel) came to him and gave him the first words of the Quran. This marked the beginning of an important adventure. Prophet Muhammad (PBUH) started receiving messages from God, which were sent through Jibreel. These messages came over the next 23 years. The first verses came from Surah Al-Alaq and told Prophet Muhammad (PBUH) to read and learn. This moment was very special because it started a big change in the world, helping people understand God and live better lives.
Duration of Revelation
The Quran was not given all at once like most books. Instead, it was revealed over 23 years. This means the Prophet Muhammad (PBUH) received messages from God bit by bit, over a long time. The messages came in different parts because the community of Muslims faced many different challenges. These messages were given in two main times. The first part was when the Prophet lived in Mecca before he moved to Medina. During this time, the messages focused mostly on teaching people about believing in one God, called monotheism. The Prophet was also taught to remind people to be good and kind to others, follow moral values, and act justly.
After the Prophet moved to Medina, the messages changed a little. They taught people how to live together fairly. The messages gave rules for things like marriage, business, and what is right and wrong. They also showed leaders how to treat others. The Quran gave guidance for all parts of life. It helped when Muslims were few in Mecca and when they became more in Medina and needed more rules. This long time of teaching made Islam’s rules clear and helped people with the challenges they faced.
Oral Preservation of the Quran
In the time when the Quran was revealed, many people in Arabia loved to memorize things. This was because oral tradition, or memorizing stories and information, was very important in their culture. They did not have many books like we do today, so people would memorize important things and share them with others. The Prophet Muhammad (PBUH) followed this tradition. Whenever he received a new message from God, he would memorize it and then tell it to his companions. These companions, who were close friends of the Prophet, would listen carefully and also memorize the words. This way, the teachings of the Quran were passed on from person to person.
As more and more people learned the Quran, they would also teach it to others. It became a common practice for the Muslims to memorize the Quran. Many companions of the Prophet were known as “Hafiz,” which means someone who memorizes the entire Quran. This helped keep the Quran safe and protected from being forgotten or lost. The Quran was deeply rooted in the hearts of the people because they remembered it by heart, not just by reading it. This method of memorization was important because it allowed the Quran to be preserved in its original form, without any changes. Even today, many Muslims around the world memorize the Quran, keeping the tradition alive. The oral preservation of the Quran helped make sure that the words of God were always with the people and would never be lost.
Role of Huffaz (Memorizers)
Huffaz are people who have memorized the whole Quran. They remember every word by heart. Long ago, when the Quran was first revealed, people would memorize the verses to keep them safe and share them. Prophet Muhammad (PBUH) told his friends to memorize the Quran, and many of them became Huffaz. They worked hard to learn and remember the Quran. They repeated the verses until they knew them perfectly. This was not easy, but it was very important to protect the Quran and pass it down to others.
Today, millions of people around the world become Huffaz. They spend many years learning and memorizing the Quran. In many countries, children start learning the Quran when they are young and keep practicing as they grow. Some people spend their whole lives memorizing the Quran. When they finish, they are called Huffaz. This tradition helps keep the Quran safe and ensures the words stay the same as when they were first revealed to Prophet Muhammad (PBUH). Huffaz plays an important role in protecting the Quran. They make sure it is passed on correctly to future generations. Thanks to the Huffaz, the Quran stays safe, and its teachings guide Muslims all over the world.
Written Preservation During the Prophet’s Lifetime
During the time of Prophet Muhammad (PBUH), the Quran was not only memorized but also written down. There were no books like we have today, but people used the materials they had available to write the Quran’s verses. Some of the materials used were things like parchment, which is a type of paper made from animal skin, animal bones, palm leaves, and even stones. These materials were not very easy to write on, but the people at that time used them because they were all they had. The Prophet’s companions, known as scribes, would write down the verses whenever the Prophet would recite them.
These written pieces were scattered in different places, and they were not put together in one big book. Instead, they existed as small fragments or pieces of writing. Each fragment had parts of the Quran written on it. For example, some verses might be written on a piece of palm leaf, while others could be written on a piece of stone or bone. While the Quran was written down in these different ways, it was not yet in one book form that we see today. However, even though the Quran was written on these different materials, the people made sure to keep it safe and organized. These written pieces, along with the memorized parts, helped to preserve the Quran’s words during the Prophet’s lifetime. Later, after the Prophet’s death, these pieces were gathered together to create the full written Quran that we have today.
Scribes of the Prophet
The Prophet Muhammad (PBUH) had many trusted companions who helped him in many important ways. One of the important jobs they did was to write down the words of the Quran as they were revealed. These companions were called scribes. The Prophet appointed some of his closest and most trusted companions to be scribes, and one of the most well-known scribes was Zaid ibn Thabit. Zaid was very smart and had a great memory. He was chosen by the Prophet (PBUH) because he was trustworthy and skilled at writing.
Whenever the Prophet received a new message from Allah, he would tell his companions. The scribes would then write it down. They made sure to write every verse carefully so nothing would be lost or changed. They used materials like parchment, animal bones, and palm leaves to write the verses. The scribes worked hard to write every word correctly. Their work helped keep the Quran safe during the Prophet’s time. After the Prophet passed away, these pieces of the Quran were gathered together to make the full Quran we have today. Thanks to the scribes, the Quran was carefully written and passed down correctly to future generations.
Compilation After the Prophet’s Death
After the Prophet Muhammad (PBUH) passed away in 632 CE, something very important happened. There was a battle called the Battle of Yamama, and many of the people who had memorized the Quran, known as Huffaz, were martyred during this battle. This was a big problem because so many people who had memorized the Quran were now gone, and there was a fear that parts of the Quran might be lost forever.
To make sure the Quran was safe, Caliph Abu Bakr (RA) decided to collect it into one book. He knew it was very important to protect the Quran for the future. He asked Zaid ibn Thabit, a trusted companion of the Prophet, to lead the work. Zaid gathered all the pieces of the Quran and put them into one complete book.
Zaid ibn Thabit was very careful in his work. He went through all the written pieces of the Quran, and he also asked people who had memorized the Quran to make sure everything was correct. Zaid made sure to check every verse with other pieces of the Quran and with the people who knew it by heart. This way, they could be certain that they had every part of the Quran and that it was correct.
After a lot of careful work, the Quran was finally compiled into one book. This was an important moment in history because it made sure that the Quran would be preserved for future generations. Thanks to the work of Caliph Abu Bakr (RA), Zaid ibn Thabit, and many others, the Quran was safely collected and protected.
During the time of Caliph Uthman (RA), there was a problem with how people read the Quran. People from different places spoke differently, so they sometimes read the Quran in different ways. This confused. The leaders saw that they needed to make sure everyone read the Quran the same way.
To fix the problem, Caliph Uthman (RA) decided to make one official version of the Quran. He wanted everyone to read it the same way. He asked for the Quran to be written carefully and correctly, just as the Prophet Muhammad (PBUH) had taught. Once the text was ready, Caliph Uthman (RA) sent copies of the Quran to all the big Islamic centers so everyone could use the same version.
To stop any confusion, Uthman ordered that all other copies of the Quran with small differences be destroyed. This helped everyone read the Quran the same way. Thanks to Uthman, the Quran was unified. Now, all Muslims can read the Quran the same, no matter where they live. This helped keep the Quran accurate and made sure everyone could follow the same teachings.
The Quran’s Authenticity Over Time
The Quran is a very special book because it has stayed the same since it was first revealed to Prophet Muhammad (PBUH) more than 1,400 years ago. Even though many years have passed, the Quran’s words have never changed. This is because the Quran was preserved in two ways: people memorized it and wrote it down. Many people, known as Huffaz, memorized every word of the Quran, and they taught others to do the same. This helped protect the Quran from being forgotten or changed.
Also, during the time of Prophet Muhammad (PBUH) and after his death, the Quran was carefully written down by trusted companions. They made sure that every word was recorded exactly as it was revealed. Even though the Quran was passed down for so many years, its words have stayed the same because of these efforts. Because of all this hard work, the Quran is one of the most accurately preserved books in the world. Today, people can still read the same Quran that was revealed to Prophet Muhammad (PBUH), and it has not changed at all. This is a very important part of the Quran’s history, showing how carefully it has been protected over time.
Role of Modern Technology
Today, technology helps keep the Quran the same and easy to share with everyone. Computers and machines are used to print the Quran. They make sure every copy has the same words with no mistakes or changes.
Before, people had to write the Quran by hand, and sometimes small mistakes could happen. But now, thanks to technology, we can print many copies quickly and easily, and they will all be identical. This helps keep the Quran’s message pure and safe, no matter where it is printed or who reads it. Digital tools also make it possible to share the Quran online, so people all over the world can read it on their phones, tablets, or computers. This means that the Quran can reach more people than ever before, and everyone can have access to the same words, no matter where they are. By using technology, we can make sure that the Quran stays the same as it was revealed to Prophet Muhammad (PBUH), even in today’s modern world.
Importance of the Quran’s Timeline
Knowing the timeline of the Quran, or when and how it was revealed and written down, is very important for understanding its special meaning. The Quran was revealed to Prophet Muhammad (PBUH) over many years, and it was carefully preserved by his companions. This shows how much dedication the early Muslims had to protect the words of God. They worked hard to make sure that every word was remembered and written down just as it was revealed.
The timeline shows how God’s plan unfolded and how He gave guidance to Muslims over time. The Quran wasn’t given all at once, but in parts, so people could understand it better. The Quran stayed the same for many years, which shows how God protected it. Learning about this history makes our faith stronger. It helps us remember God’s plan and how early Muslims worked to keep His word safe for us today. The timeline also shows how the Quran has stayed the same and still guides people around the world.
The timeline of the Quran is very important because it helps us learn about the history of Islam. The Quran was given to Prophet Muhammad (PBUH) over many years. The Muslims worked hard to protect it and pass it down to future generations. This shows how much the early Muslims cared about keeping God’s words safe. They made sure to remember and write down every word of the Quran to share it with everyone.
Over time, many Muslims memorized the Quran. They also wrote it down on things like parchment and stone. After the Prophet died, the leaders made sure the Quran was put together in one book and shared with everyone. This hard work helped keep the Quran safe for over 1,400 years. Today, we still read the same Quran that was given to the Prophet. This shows how much the Quran means to Muslims and how much effort went into protecting it. The Quran’s history teaches us to protect our sacred books and share them with others.
The Quran’s journey started when it was first given to Prophet Muhammad (PBUH). It was revealed over 23 years ago. After that, it was carefully written down in 650 CE. The Muslim community worked hard to keep it safe. The Quran has been perfectly protected, and today, it is the same as when it was first revealed to the Prophet.
Even though the world has changed a lot over the years, the Quran remains the same, and this is very special. It guides Muslims, meaning it helps them know how to live a good life. It also gives them comfort because they know that the words in the Quran are from God and will never change. The Quran inspires people to be better, to have faith, and to follow the right path.

How Web Browsers Work
Web browsers work behind the scenes to retrieve and display web pages, allowing users to interact with online content. Understanding the basic workings of a web browser can provide valuable insights into how we access and navigate the vast landscape of the internet.
Here is a simplified breakdown of the fundamental steps involved in how web browsers work:
- URL Parsing: When a user enters a web address or clicks on a hyperlink, the browser parses the Uniform Resource Locator (URL) to identify the website’s domain name, protocol, and path.
- Requesting the Web Page: The browser sends an HTTP (or HTTPS) request to the web server hosting the website, specifying the desired web page. The request includes information such as the browser type and version.
- Rendering the Web Page: The browser’s rendering engine interprets the HTML code and constructs a Document Object Model (DOM) representing the web page’s structure. It then applies the CSS styles to the appropriate elements, resulting in the visual appearance of the page.
- Fetching Additional Resources: The browser continues to fetch additional resources referenced within the web page, such as images, videos, and external scripts. This process may involve multiple server requests and parallel downloads to optimize performance.
- Displaying the Web Page: As the web page finishes rendering and all resources are loaded, the browser displays the final result on the user’s screen. This includes the rendered text, images, videos, and other multimedia elements.
- Handling User Interactions: The browser listens for user interactions, such as clicking on links, submitting forms, or scrolling through the page. When an interaction occurs, the browser triggers the corresponding actions, such as navigating to a new web page or performing an action on the current page.
Web browsers work tirelessly behind the scenes to make the entire process seamless for users, ensuring that web pages are delivered quickly, rendered accurately, and presented in a visually appealing manner. The complex interplay between the various components of a web browser enables us to browse the internet efficiently and interact with online content effortlessly.

TAVERNER, WILLIAM, planter, trader, and surveyor; b. possibly in Bay de Verde, Nfld., about 1680, perhaps the son of William Taverner, a planter; d. probably at Poole, Dorset, England, 7 July 1768.
Information about William Taverner’s early life is difficult to find and substantiate. Apparently he was a member of the Taverner family of Poole and Bay de Verde, Nfld. – a moderately well-off group which divided its time between Poole and Newfoundland. From at least 1698 he was owner of a plantation in St John’s. A document found in Dorset mentions that another planter’s son, John Masters, was apprenticed to William about 1700–1. In 1702 William is mentioned as a planter of Trinity and a trader from Poole to Trinity. It appears that he captained Newfoundland fishing vessels and led a privateering raid on the French fisheries. About 1705 he was able to move his wife Rachel and his family to Poole and to live there himself during the winters. By that time he owned one small vessel, the William.
William Taverner and his brother, Abraham, emerge in 1708 as opponents of Major Thomas Lloyd*, commander of the Newfoundland garrison. Abraham, an obscure figure, was Newfoundland agent for the London merchant, James Campbell, who had extensive plantations at Bay de Verde. Campbell was financial agent in London for Captain John Moody* who had been commander of the Newfoundland garrison during Lloyd’s absence in 1704–5 and who was an avowed adversary of Lloyd. Although many of the Newfoundland planters tried to keep away from both Lloyd and Moody, William Taverner led a group which, early in 1708, complained about Lloyd’s exploitation of the colonists.
By 1712 he began to present memoranda to the Board of Trade on the French possessions in Newfoundland and elsewhere on the Gulf of St Lawrence. Some of his London associates regarded him, by 1713, as an expert on the location, character, and potentialities of the fishery based at Placentia (formerly Plaisance) and extending to southwest Newfoundland, an area ceded to Great Britain by the treaty of Utrecht. Taverner had also been involved in a plan to develop cod fisheries in the Newfoundland manner on the northwest coast of Scotland, a venture by the London fish merchants who found the war interfered with the Newfoundland fishery.
On 21 July 1713 Taverner was commissioned as “Surveyor of such part of the coast of Newfoundland and the Islands adjacent as the French have usually fished upon and wherewith our subjects are at present unacquainted.” Frequently consulted by the Board of Trade during the next eight months, he was able to pass on useful information as well as advice about the situation in the newly acquired territories. When Taverner arrived at Placentia on 27 June 1714, Lieutenant-Colonel Moody, who had been designated deputy governor of Placentia, put a ship at his disposal to begin the survey. On 23 July Taverner set out to discover the nature and extent of the outlying French settlements on the island of Saint-Pierre and elsewhere, to report what French ships were fishing, and to carry through a charting operation designed to provide sailing information for English fishermen.
The transition from French to British control was difficult; the French under the supervision of Philippe Pastour* de Costebelle were evacuating the population to Île Royale (Cape Breton Island) and threatening those who remained and took the oath of allegiance that they would be treated as traitors. At Saint-Pierre Taverner had a lively summer trying to impose the oath of allegiance on the French. He had some trouble too with one William Cleeves of Poole over the sale of salt, and was accused by him of charging the French for surveying their plantations, of compounding with French ships which came to trade, and of engaging in trade on his own account, sending home, for example, ten hogsheads of oil to Poole. On 22 Sept. 1714 Taverner returned to Placentia and made a full and interesting report. He thought the possibilities of exploiting the salmon fishery were good and was most optimistic about building up a fur trade, having engaged a Canadian with a knowledge of Indian languages to make contacts for him.
Meantime, back in England, there was some discussion about whether Taverner’s appointment should be continued: the fishing ports wished the survey completed, though only the Londoners named Taverner as surveyor, so it may be the accusation made in 1715 that he was appointed to serve sectional interests (those of the Londoners against the Westerners) had some foundation. Many Western merchants protested that Taverner was unqualified for the surveying work. William Cleeves’ complaints caused Taverner’s wife some anxiety but she put up a spirited defence of her husband and pointed out that his salary of 20 shillings a day had not been paid, so that she was in grave financial difficulties. The arrival in February 1715 of his report together with his “new chart of the islands and harbor of St. Peter’s [Saint-Pierre], with the island of Columba and the adjacent rocks,” stifled criticism and led to his getting his salary, expenses, and – most important – reappointment. Taverner continued his work in 1715. With his second report was a “new chart or map of Newfoundland from Cape St. Mary’s to Cape Lahun [Cape La Hune],” which it was suggested should be published at public expense.
In the winter of 1715–16 Taverner was again in England explaining to the Board of Trade the complex position of the former French coasts. At Placentia Moody had bought foreshore rights from departing French settlers, and Taverner had made similar purchases on Saint-Pierre despite the fact that this action was in direct defiance of the policy of the Committee for Trade and Plantations. Consequently Taverner and Moody deprived the English fishing captains of the free “fishing rooms” – spaces for handling and drying the fish – to which they claimed they were entitled. Taverner maintained that he had protected the handful of French who remained at Saint-Pierre from intimidation by William Cleeves and others, and had left adequate “fishing rooms” free for such vessels as appeared. Taverner seems to have convinced the Board of Trade that the charges against him were exaggerated, it being understood that he might have to make some money to supplement his irregularly paid salary but that he ought not to oppress his countrymen in the process. He returned to Newfoundland on 8 March 1716. In 1718 the Board of Trade reported his services were satisfactory and it seems that in this year he wound up his survey of the former French possessions in Newfoundland and was paid off.
From 1718 to 1725 it seems probable that he fished and traded annually from Poole with the Placentia–Saint-Pierre region. In March 1726 he was involved with other Poole merchants (having apparently cut his links with the Londoners) in a plan to develop the salmon fisheries of southern Newfoundland. He offered to combine a reconnaissance of the fishery, which he was about to make, with a survey of the west and northwest coasts of Newfoundland. He had earlier drawn attention to the continued French and Basque presence on the south coast near Cape Ray, but the west coast was still unknown to the English. He undertook at his former rate of pay to complete a survey in two and half years. This time his plans were supported by both London and Westerners, showing that the value of his earlier work was appreciated by the fishing interests; his plans were also endorsed by the Board of Trade. This second survey, carried out between 1726 and 1728, has not left much in the way of documentation, but as a result he was able to disturb the virtual monopoly held by the Basques on the west coast fishery. He also had begun to engage experimentally in fishing and trade in the area.
By 1729 Taverner was operating on his own account also in the Strait of Belle Isle and met some resistance from Breton fishermen at Cap de Grat (Cape Bauld). At this time he evidently resided in St. John’s for part of the summer and his attempt to collect rents from some properties he had earlier held caused trouble. He proposed to sail right round Newfoundland in 1730, hoping for some financial assistance from the government. It is unlikely that he obtained further subsidies, though he continued his trade with the outlying parts of Newfoundland. Taverner made an important report early in 1734, showing that the French sent Indian hunting parties in winter from Île Royale to western Newfoundland, thus prejudicing the English market for furs, and that a settlement of French runaways had grown up at Port aux Basques, which was becoming a centre for illegal trade by the French in fish, oil, and furs. He was anxious that this should be stopped, and suggested he be appointed to do it. His offer was not taken up, but Lord Muskerry, who was going out as governor, was told to instruct the French to leave and to expel them if necessary. It was perhaps thought that Taverner was getting rather old for further services, and indeed he is found in 1739 asking for a gratuity for what he had done.
The outbreak of war with Spain and the growth of friction with France led the fishing interests early in 1740 to raise the question of further fortifications in Newfoundland, and Taverner appeared for the last time before the Board on 14 Feb. 1740 to give his advice. He presented an elaborate review of the fishery 1736–39, showing that it represented a turnover of £227,000 per annum, and employed 8,000 men and 21,500 tons of shipping so that it deserved full protection.
William Taverner was a remarkably regular and persistent trader in the fishery and his ships can be traced back and forward across the Atlantic to the mid-1750s. By this time his son William was also a ship’s captain and an agent for some of the Poole merchants trading to Trinity. In 1762 the son was a signatory to a petition concerning the French capture of part of Newfoundland. The father’s signature does not appear and one presumes that he was no longer active.
William Taverner did good work in opening up the former French shore in southern Newfoundland to the knowledge of Englishmen, though his surveys were, after 1714, verbal reports rather than sailing charts, and it is not known how efficient a cartographer he was. He also pioneered English trade and fishery in the French areas and was the first to make effective use of the west coast, which Englishmen had avoided.

How To Conduct Usability Testing with Maze
Usability testing often requires laborious procedures that get some designers discouraged at the mere thought of conducting one. Nonetheless, it is arguably one of the most important tasks user experience designers perform. Without usability tests, the whole user-centered design strategy falls apart.
What if there were alternatives to the expensive moderated usability testing and at the same time, tools that can help designers collect just as much quality research data?
Well, there are several of them. In this tutorial, we will consider a popular one— Maze. You will learn how to conduct Maze usability testing to obtain insights for your design process. But before then, a little background.
What is usability testing?
Usability testing is the process of testing your designs by observing users' interactions with them. The goal of this activity is to obtain feedback that will fuel further iterations in the design process, i.e to aid the refinement of the product.
Usability tests occur after the designers have interpreted some of their concepts into meaningful designs. These tests can take place at different points of the design, for instance, designers can test early concepts using Lo-Fi prototypes, and later on, with Hi-FI prototypes that look just like the final product.
Types of usability testing
There are two kinds of tests designers perform:
- Moderated tests: the test facilitator has to be present in this kind of usability testing. These functions include putting users through tasks where necessary, and most importantly— physically observing how they interact with the product and putting down these observations.
- Unmoderated: as you might have guessed, moderated tests come with limitations, sometimes it might be necessary to conduct usability studies with a large audience from different demographics or locations. In such situations, physically observing users is an expensive approach. Unmoderated tests do not need the physical presence of a facilitator. You can conduct them via online tools.
What is Maze usability testing?
Maze is a platform that enables you to conduct an unmoderated usability test with ease. Impressively, the platform allows you to test users with just about any kind of usability task allowing you to obtain both qualitative and quantitative data.
Using Maze, UX designers do not need much involvement in the process, you simply set up the prototypes to test, invite users by sharing links or through the platform itself after setting up tasks for them to complete to collect useful data on your design — even heat maps showing their click patterns.
Such tools that help user experience designers automate processes can help boost their productivity.
So let's jump right into it. In the next section, we will look at how to use Maze in six easy-to-follow steps.
How to conduct usability testing with Maze
Maze is a cloud-hosted platform, hence, there's no need for any installations and the like. To test your designs, follow the steps below:
Step 1: Create the prototypes in your favorite design software
Every usability test starts with prototypes. In the design thinking framework used by UX designers, the Test phase usually follows the UX prototyping phase, though it is not a linear framework. To conduct quality tests, you need prototypes that closely mimic the product.
Creating prototypes is as easy as connecting different designs representing screens/pages in your product to mimic the expected navigational flow of the product.
Nearly all design and prototyping tools make room for this, and they usually provide a shareable link to that prototype.
Step 2: create a new Maze project
To import your prototype to Maze, you need to get the link to your prototype, if you are doing this from Figma:
- Simply head over to the prototyping page and copy the link provided.
On clicking the flow, you will be able to copy the link to it.
- Head to the Maze software and open a new project
Note: instead of starting from scratch you can use one of the provided templates to perform your tasks.
These templates contain predefined questions and procedures that you might need to edit. But for the sake of this tutorial on how to use Maze, we just use a blank project.
Step 3: Create your Maze mission block
On clicking start from scratch, the page below opens. Here you are expected to add a block.
There are several tasks you can perform on the Maze platform, from usability testing to yes/no questions and opinion scales. All tasks are conducted in a "Maze"; this is what they represent a typical project as.
Each project contains Block types, which is just how Maze categorizes tasks you can conduct. There are two main kinds of Blocks - Missions and Question Blocks. For usability tests, you need to create a Mission Block.
- Simply select Mission from the list of Block types as shown below:
Next, you have to enter the details needed for the Maze test online. They include the task, description and prototype.
- The task is a brief heading describing the usability testing. It can be whatever you chose, but it's better to use one that relates to and finely captures the task users are to perform in your usability test.
- The description covers in more detail the user tasks. You can provide the instructions and other important information you want test participants to know in this space. It's recommended to clearly describe the activities of the task.
- The prototype is the group of pages that participants will interact with. You will import this from your design software. We will talk more about doing that in the next step.
Step 4: Import the prototype
Remember the link you got from step 2? Now is the time to use it.
- Click on the Add prototype button
- Enter the link in the space provided
- Press Import.
Note: it's important to test a single flow at a time. Trying to test prototypes with multiple flows can result in the user following an unintended path and thereby failing to complete the given task.
Step 5: Set up the Maze mission
The goal of every usability test is to create tasks and collect data on how users perform them. Therefore, the next vital step is to create the Path. This refers to the expected routes users are to take to the finish point of the task.
Setting the path is as simple as clicking the various pages that link to one another in your navigational flow in the expected order.
- Scroll down to Expected paths
- In the preview section by the right, simply navigate through the prototype from the first page to the last. This loads up the expected user path.
Add the follow-up Questions
After completing a task, it's important to follow participants up with questions regarding their experience. Using the Open Questions block you can add open-ended questions to your mission in Maze.
To add questions, do the following:
- Click Open Questions under the Questions block on the left side of the Build page.
This will lead to the page below where you can enter a question:
Now, when users complete your task, they will be asked whatever questions you entered.
Step 6: Take the usability test live
With all the necessary elements in place, you can now take your test live for participants to join!
- On pressing the Continue button on the Build page, the Share page below opens.
There are three major ways to invite participants: sharing a link, sending out a campaign via Email and hiring participants from the Maze platform.
- Select Copy Maze link
- You can send this link via any means of your choice to your audience.
Edit a live Maze
Now, your Maze is live and participants are interacting with it in real-time. What if you realize all of a sudden that there are errors in your setup?
In our case, there are a lot of misspellings in our description. So is there something we can do about this?
Luckily, there is.
Maze allows you to edit a project even after taking it live. However, some aspects aren't safe to edit as doing that might affect your test outcome.
- Click on the Settings icon.
- Select the Edit Maze option.
Now, you can change the details of your task.
- After making your changes, select Update the Maze.
Analysing test data
Maze delivers different kinds of data from usability tests. You can view the results of your test from the Results page. You will find information on Direct and Indirect Successes, the duration for completion of the test and others for each of the test participants. You can download this as a report as well.
To view the heat maps for each page in your task:
- Click on the paths segment ➡ view heatmaps.
- Select a page.
Stopping the task
At some point, you might decide you have collected enough data for your usability test. The final step of the process is to end the live Maze.
To stop a usability study on Maze, follow the process:
- Go to settings ➡ stop recording
Why use Maze usability testing?
The benefits of testing your prototypes with Maze include:
Cost: recruiting participants for a usability test is often a hassle, more so, if you are after obtaining a large amount of data in which case you need probably thousands of users. The cost for such a study is even accelerated for moderated tests where you might need several facilitators. With usability testing tools like Maze, you can bypass many of these hurdles.
Speed and productivity: UX designers, whether full-time workers or freelancers, understand the place productivity has in the growth of their careers. Automating tasks such as UX research and usability testing helps them be more productive because they free up time to attend to other activities. Software tools such as Maze can help UX designers run and analyse usability studies faster without giving up on quality.
Freedom with questions: To ensure that the UX designer obtains quality data that truly represents the user's opinions and motivations, it is often necessary to employ a variety of question types. For more depth, designers use open-ended questions, opinion scales, etc, that enable users to freely express themselves. Maze enables you to ask users follow-up questions regarding the interface they interacted with— this can help you obtain more meaningful insights.
Quality data: you can analyse a variety of data thanks to the platform's support for multiple data types. One of them is heat-maps.
Heat maps show the click patterns on each interface in a visual format. The varying visual density can help identify parts of the screen with the most touches. This feature is important to UX designers as it can help them detect missed clicks that are probably due to poorly designed calls to action.
Help source participants: a Maze test online offers you the means to recruit participants as well, for a lot of designers, sourcing participants is usually a pain. With Maze, however, you can simply create your tasks and request for the platform to offer participants to partake in your test. However, this feature isn't free.
Live recordings: another interesting feature of the platform is the ability to record live user interactions in your studies. This can be valuable data to designers as it can help them gain a deeper understanding of user behaviour. Just like sourcing participants, this is a paid feature.
To be productive as a UX designer you need to consider alternatives to the more traditional approaches to UX design processes. Using software tools like Maze, designers can easily conduct usability analysis, obtain quality and diverse data, incorporate this into their design thinking strategies and create products that reflect an understanding of the user. | <urn:uuid:c9d31682-7689-4528-b6f9-0dc401379f68> | CC-MAIN-2024-51 | https://www.carlociccarelli.com/post/how-to-conduct-usability-testing-with-maze | 2024-12-07T23:58:22Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066433271.86/warc/CC-MAIN-20241207224914-20241208014914-00800.warc.gz | en | 0.935227 | 2,374 | 2.734375 | 3 |

By Karl A. Scheuerman
In the history of warfare, belligerents have often targeted food supplies to force opponents into submission. However, in America’s wars over the last century, threats to domestic food security have been minimal. In many ways, the United States enjoyed insulation from combat conditions overseas that could have otherwise disrupted the country’s ability to feed itself. Complacency in relative isolation from disruptive food shocks is no longer a luxury the United States can afford. We are now in an era of increased globalization, where food supply chains span the oceans. In addition, America faces the renewed rise of strategic competition as China and Russia seek to replace U.S. power across the globe. Given these new realities, timely evaluation of potential vulnerabilities to American food production is necessary.
Among rising strategic competitors, Russia has explicitly demonstrated a clear willingness to target food systems. In its current war against Ukraine, the Russian military has relentlessly attacked wheat supplies and production. Yet despite the critical importance wheat plays as the foremost American dietary staple, its production is indeed vulnerable to disruption should Russia choose to act. While a full-scale conventional war with Russia is unlikely because of nuclear deterrence, the Kremlin has repeatedly demonstrated a willingness to disrupt foreign interests over the past several years, from election interference to trade wars. Targeting the U.S. wheat industry could become another preferred option for the Kremlin to wage adversarial competition at a level below the threshold of armed conflict. Given the emerging global security environment, the U.S. Government should reevaluate current policies to ensure the resilience of the wheat industry against this threat.
Wheat Is King in America
Grain plays an enormous role in feeding the world. Approximately 47 percent of all human caloric intake today comes from grains, and the United States is a significant contributor to global grain supplies.1 According to the United Nations (UN) Food and Agriculture Organization, the United States is the second largest grain producer in the world (behind only China), producing over 450 million metric tons, which represents 15 percent of the worldwide supply.2 Of all grains the United States produces, Americans consume more wheat than any other, making it the country’s most essential food staple.3 U.S. farmers raise greater volumes of corn and soybeans, but most of those commodities are used for livestock feed and biofuels.4 Due to wheat’s central role in the American food system, consumer demand for products derived from wheat is “relatively stable and largely unaffected by changes in wheat prices or disposable income,” according to the U.S. Department of Agriculture (USDA).5 As shown in figure 1, demand for wheat in the United States continues to grow. Thus, wheat represents a worthwhile case study in evaluating U.S. resiliency to food disruption in the context of strategic competition, specifically with Russia.
Some may find it hard to envision a scenario where the United States would experience wheat shortages. However, recent examples of modern countries suffering significant wheat production losses exist. Russia, the world’s largest wheat exporter, suffered extensive drought and wildfires in 2011 and lost one-third of its national wheat crop as a result.6 China, the global leader in wheat production, suffered wheat crop losses of up to 16 percent between 2000 and 2018 due to pests and pathogens.7 Another breadbasket of the world, Ukraine, will likely see its 2022–2023 wheat output decline by 41 percent compared to the previous year because of the Russia-Ukraine war.8
Implications of Domestic Wheat Shortages
If America were to experience wheat shortages, the implications would be significant. As the United States is the third largest wheat exporter on the global market, a drop in U.S. supplies would negatively impact world food prices.9 Following the decline in Russian wheat exports in 2011, food prices spiked and contributed to dramatic instability in countries dependent on imports, helping give rise to the Arab Spring.10 Trade partners, including key allies such as Japan and South Korea, who rely on U.S. wheat imports would likely feel the pinch most acutely in countering Russian and Chinese influence.
But significant domestic concerns could pose a greater risk. In 1906, journalist Alfred Henry Lewis presciently stated, “There are only nine meals between mankind and anarchy.” Unlike any other commodity, food is the one we cannot survive without. If interruptions to the food supply occurred, the public’s confidence in future availability might begin to erode, spreading fear. Those now living below the poverty line would suffer the most, but even the broader citizenry could start losing confidence in the government’s ability to provide basic needs, fueling an already tense and polarized domestic political climate.
If disruptions affected U.S. wheat production, food substitutes would play a role in softening the impact. However, given wheat’s primacy in our food system, the volume of substitutes needed could pose major challenges. A national grain reserve, similar in concept to the Strategic Petroleum Reserve, would be a logical buffer to mitigate shortages, but unfortunately, no such reserve exists. Despite producing more grain than any other country on earth, China has established a national reserve that reportedly now contains at least 2 years’ worth of grain supplies should the country need it.11 The United States has previously tried establishing a national grain reserve, most recently with the Bill Emerson Humanitarian Trust. However, the trust sold off its commodity holdings in response to food price spikes resulting from the 2008 financial crisis and now only holds cash reserves to help pay for famine relief needs abroad.12
Should a worst-case scenario arise where the entire annual U.S. wheat harvest failed, existing stocks would quickly evaporate if current consumption levels remained constant. In the last crop year of 2021–2022, American farmers produced 1,646 million bushels of wheat, while domestic demand (comprised of human food use, animal feed, and seed) for the year totaled 1,117 million.13 After factoring in exports and the previous year’s residuals, the remaining stock of U.S. wheat after the previous crop year was 669 million bushels, and this is expected to decrease further next year to its lowest levels since 2007–2008 (table 1).14
Applying a “time-to-survive” analysis to the hypothetical worst-case scenario, which measures the maximum duration that supply could match demand (assuming the previous domestic demand level held constant and exports were canceled), existing domestic wheat stocks would last only about 7 months.15 Unlike other industries, agriculture does not have the option of surging production when a crisis arises as it is constrained by annual growing seasons. The United States could not replenish its wheat stocks with domestic production until the next summer harvest season.
Food shocks and price spikes resulting from the COVID-19 pandemic and Russia’s war in Ukraine have helped Washington realize our food system’s fragility. The latest National Security Strategy under President Joe Biden cites food security as one of the top five shared global challenges. It highlights global initiatives the United States is currently leading, including efforts to urge other states to commit to “keeping food and agricultural markets open, increasing fertilizer production, and investing in climate-resilient agriculture.”16 These efforts are worthwhile, but America must ensure its increased focus on global food insecurity does not turn a blind eye to potential vulnerabilities in domestic food production that a disruptive adversary such as Russia could exploit.
Moscow’s Increasingly Disruptive Actions
Over the past two decades, while the Russian Federation has enjoyed a resurgence of economic growth and global influence under Vladimir Putin’s leadership, the Kremlin has demonstrated a repeated willingness to undermine U.S. interests. The reasons for this approach are rooted in what has become characterized as the Primakov doctrine, which “posits that a unipolar world dominated by the United States is unacceptable to Russia.”17 In operationalizing the Primakov doctrine, Russia has been conducting a hybrid war in part to “foment chaos, create distrust in U.S. institutions, and target the preexisting divisions in the country.”18 Through these actions, Russia has earned a reputation as a perilous threat “with the goal of overturning key elements of the international order.”19
There is no shortage of examples illustrating why Russia is now characterized this way. The United States has attributed several significant cyber attacks20targeting American industry and governmental organizations to Russia in recent decades.21 The Kremlin has also gone to great lengths to interfere with the democratic process Americans cherish. The clearest example of this approach was during the 2016 Presidential election. According to the U.S. Intelligence Community and Department of Justice investigations, the Kremlin directed extensive information warfare operations to influence the election outcome, resulting in distrust among the U.S. citizenry in the reliability of our electoral system.22
Russia is now also seeking to undermine the U.S.-led global economic system. Suffering from unprecedented Western sanctions as punishment for its war in Ukraine, Russia is countering with its own strategies to establish a global economy that excludes the West. Not only have the Russians cut natural gas supplies to Europe, but they are also replacing access to Western marketing by increasing trade with China, India, and other countries. Russia has also been championing its own alternative to the SWIFT international financial messaging system.23
These examples demonstrate Russia’s repeated attempts to undermine American strength and interests. Outcomes from these efforts have resulted in various levels of success in sowing seeds of domestic chaos to destabilize U.S. society. Should the Kremlin succeed in significantly disrupting Americans’ ability to sufficiently access cheap and convenient food, the impact could become far more intense than what Russia has achieved to this point.
Experienced Cereal Killers
While their attempts to disrupt U.S. interests in the post–Cold War era have yet to target food directly, the Russians have found it a preferred tactic elsewhere. In fact, during their current war in Ukraine, attacking wheat storage and production has been a top priority, and they have done so with remarkable efficacy. Ukraine is one of the world’s most productive breadbaskets, producing over 85 million metric tons of wheat annually.24 Ukraine was the world’s fourth largest wheat exporter on the global market during the 2021–2022 crop year.25 Recognizing Ukrainian grain as a critical center of gravity, Russian forces have employed a relentless multifaceted strategy to destroy that element of the Ukrainian economy.
The first element of this strategy is the theft of Ukrainian agricultural machinery. Since the early weeks of the war, media outlets have reported multiple instances of Russian forces ransacking Ukrainian grain stocks, shipping their contents back to Russian territory and sending it to Russian cargo vessels for export to global Russian trading partners.26 Some estimates claim that millions of tons of grain from eastern Ukraine have been seized, triggering nightmares of the Soviet-induced Ukrainian famine of 1932–1933.27 Russians looted farm machinery dealerships and stole combines, tractors, and implements.
The second component of the Russian strategy to eliminate Ukrainian wheat is destruction. Not only have battles prevented farmers in certain regions of eastern Ukraine from tending to their fields, but Russian forces have also laid waste to Ukrainian cropland by burning vast acreages across the Donetsk, Mykolaiv, and Kherson regions. Russian bombing and missile strikes have destroyed the logistical infrastructure essential to wheat production and delivery, including irrigation systems, grain elevators, and port terminals. Seeking to damage Ukraine’s ability to recover from the conflict, Russia went so far as to target Ukraine’s National Gene Bank located in Kharkiv, which served as the country’s seed bank, housing some 160,000 specimens of plant and crop seeds.28
A third pillar of the Russian strategy undermining wheat production in Ukraine has focused on Ukraine’s ability to export its grain. In the early days of the war, the Russian naval blockade of Ukraine’s Black Sea ports strangled Ukrainian exports, cutting off essential means for Kyiv to participate in global markets. Agricultural commodities are Ukraine’s top exports, including $4.61 billion worth of wheat alone in 2020.29 Blockading the Black Sea ports was painful for Ukraine and the many countries relying on Ukrainian wheat to feed their populations, contributing to damaging global food price spikes and inflation over the ensuing months. Not until August 2022 did Russia agree to lift the blockade, based on a tenuous agreement brokered with assistance from the UN and Turkey. Even since the initial agreement, the Kremlin has unilaterally suspended it once and has threatened not to renew the deal.30
Ukraine’s experience during the current Russian invasion reveals the lengths to which Russia is willing to go to intentionally attack wheat production and supplies, even when that grain is a vital component of the local and global food system. Based on this precedent, the United States and its allies must be prepared to defend against the variety of tactics Moscow could employ to attack wheat production elsewhere.
Russia’s Emergence as a Global Food Power
Competition between Washington and Moscow that is centered around grain is nothing new. Following the U.S. Civil War in the 1860s, cheap American wheat flooded global markets for the first time, pushing Russian wheat exports out of Europe. The U.S.-Russian grain trade rivalry was a key factor in conditions that ultimately ushered in World War I.31 Wheat has continued to play a major, albeit behind the scenes role in U.S.-Russian relations ever since.
When Putin became president in 2000, Russia relied on imports to meet half its domestic food needs. Prioritizing food security, the Russian president has since successfully executed initiatives to boost food production, and grain has been a critical focus. By 2017, Russia had become the world’s top wheat exporter, and the Kremlin has no plans to cede its pole position. Despite unprecedented sanctions from the West as punishment for its war in Ukraine, Russia still has plenty of buyers for its wheat exports in the Middle East and Asia as it strives to outproduce and outcompete American farmers.32 Even China began importing Russian wheat this year after previously placing a ban on it due to concerns about the presence of a crop disease (dwarf bunt fungus).33 The Kremlin’s agriculture minister is now on a mission to increase the value of agricultural exports by 50 percent by 2024.34
Recent global supply chain disruptions from events such as the war in Ukraine and the COVID-19 pandemic have highlighted Moscow’s privileged position in terms of food security. Russia is the world’s top exporter of not only wheat but also fertilizer.35 Given its relative strength in this area and a demonstrated willingness to attack Ukrainian wheat, attacking the domestic American wheat industry could become a viable option in Russia’s arsenal of hybrid warfare tactics against U.S. interests. Specific strategies Russia could employ to target U.S. wheat production can be organized into four categories of attack:
- cyber attacks targeting grain storage and transport infrastructure
- restricting fertilizer exports to U.S. and/or global markets
- manipulating international wheat markets
- agricultural biowarfare.
The following sections will explore each of these options in depth.
Disruption Option 1: Cyber Attacks Targeting Grain Infrastructure
Among the cyber-security industry, many consider Russia to be the most capable and stealthiest of America’s cyber adversaries. In addition to the notable intrusions mentioned earlier, suspected Russian adversary groups have earned their reputation for several reasons, including developing sophisticated malware that employed novel command and control techniques, exhibiting rapid breakout times, and leading the way in targeting cloud infrastructure.36
Cyber attacks crippling the food industry are not unprecedented. For example, suspected criminals successfully compromised the network of JBS S.A., a global meat processing company, hampering livestock slaughter operations and causing wholesale meat prices to spike.37 Should the Kremlin set its sights on disrupting the U.S. wheat industry via cyber means, a likely approach would be targeting the infrastructure used for grain transport and storage, specifically the grain storage elevators throughout wheat production regions. These facilities comprise an essential component of the Nation’s food system, which the Department of Homeland Security (DHS) has identified as 1 of the 16 sectors of critical infrastructure.38 Farming cooperatives operating grain elevators increasingly leverage automation technologies to handle loading and unloading functions. If an adversary gained remote access to the industrial control system (ICS) network environment, they could shut down operations, preventing grain transportation to trade markets and food processors.
Russian state-sponsored adversaries are known to have successfully targeted a critical infrastructure ICS environment, causing kinetic effects. A cyber unit within the Russian military was responsible for the attack on the Ukrainian power grid, resulting in nearly a quarter-million Ukrainians losing power for about 6 hours.39 A similar attack chain methodology could disrupt control systems for other sectors of critical infrastructure, such as grain storage facilities.
A less sophisticated means of attack on grain elevators would be to infect the traditional computer networks operating at these facilities in attempts to affect operations. This has already happened on several occasions. Between the fall of 2021 and early 2022, six U.S. grain cooperative elevator facilities experienced ransomware attacks on their business networks that inhibited processing as some were forced to adjust to manual operations. Recognizing the threatening trend, the Federal Bureau of Investigation (FBI)’s Cyber Division issued a Private Industry Notice to assist grain cooperative organizations better prepare their defenses.40 The FBI’s report also noted the potential for an impact on commodities trading and stocks that could result in food security and inflation concerns.
Another potential cyber attack against the wheat industry that could lead to severe outcomes would be a more typical intrusion into agriculture industry business networks. Large agriculture firms have not been immune from network intrusions aimed at stealing intellectual property. Unlike the other attacks mentioned, where the objective is to perform sabotage or shut down a network for ransom, cyber-security firms have noted that intellectual property theft intrusions targeting agriculture firms are on the rise.41
Should Russian-aligned adversaries gain access to sensitive agriculture industry data, they could facilitate further disruptive strategies. For example, stolen documents and data could be altered and then leaked publicly, delivering damaging false messages like the hackers who doctored data stolen from Pfizer to undermine public trust in vaccines.42 Similarly, grain pathology and trade experts note that false claims of wheat crop disease would have dramatic adverse effects on American grain exports.43 Undermining American interests related to global trade introduces additional options at the Kremlin’s disposal for disrupting U.S. wheat production.
Disruption Option 2: Restricting Fertilizer Exports
The United States is a net exporter of food. As such, some assume the country is self-sufficient in meeting domestic food needs. However, that conclusion is tenuous because American agriculture depends on imports of foreign synthetic fertilizer. Less than 1 percent of U.S. farmland is organic.44 Farming the remaining 99 percent involves conventional methods. One characteristic of conventional agriculture is the “extensive use of pesticides, fertilizers, and external energy inputs.”45 Despite the United States having a relatively robust fertilizer production industry, it does not currently provide for all domestic farming needs. According to the USDA, “The United States is a major importer and dependent on foreign fertilizer and is the second or third top importer for each of the three major components of fertilizer.”46
The three primary fertilizer nutrients required to grow crops are nitrogen, phosphorus, and potassium. Nitrogen fertilizer is derived from the Haber-Bosch process, which uses natural gas for fuel to extract nitrogen from the air to form ammonia. Phosphorus fertilizer comes from mining of nonrenewable phosphate rock. Potassium fertilizer is derived from mining nonrenewable potash. As of 2021, the United States imported 12 percent of its nitrogen, 9 percent of its phosphate, and 93 percent of its potash.47 While America imports these materials from many friendly states, some come from less-trusted trading partners. This is especially true of potash. Russia and its close ally, Belarus, combine to provide 12 percent of America’s potassium requirements and more than 15 percent of total U.S. fertilizer imports (figure 2).48
Should Russia choose to disrupt wheat production by stopping potash exports, America would need to find ways to ramp up domestic mining and production or close the gap by increasing imports from friendly trade partners such as Canada, which already supplies 83 percent of potash used in the United States. A more significant cause for concern is that Russia is the world’s largest fertilizer exporter when considering all fertilizer components and is responsible for over 15 percent of total global fertilizer exports.49 Leveraging that influence, Russia could attempt to manipulate availability on the global market, resulting in worldwide price shocks that would cascade to American consumers and place additional pressure on poorer countries already suffering from food security challenges.
Russian impacts on global fertilizer trade have already contributed to financial instability. Fertilizer prices tripled after the beginning of the war in Ukraine because Russia limited exports. These limits included restrictions on exports of natural gas, which, as noted, is a crucial component for producing nitrogen fertilizer.50 Russia also shut down an ammonia fertilizer pipeline from its Volga region to a Black Sea port to further restrict global supplies.51 The USDA characterized the situation as “Putin’s price hike on farmers.”52 These events contributed to soaring food costs, leading to the highest inflation rates in the United States in four decades.53
In late 2022, the UN warned that if fertilizer prices were not reduced, the world would face a “future crisis” of food availability. UN officials have since worked to convince Russia to increase fertilizer output.54 Thanks to rebounding global fertilizer production, fertilizer price fears have dampened for the near term.55 Nevertheless, the situation demonstrates how the Kremlin can leverage its fertilizer superiority to harm the interests of not only the United States but also the world. Unfortunately, fertilizer availability is not the only way Moscow can flex its muscle in undermining American wheat production. Undercutting U.S. grain exports is another area where the American wheat industry is vulnerable to Russian meddling.
Disruption Option 3: Undercutting U.S. Wheat Exports in Global Markets
America’s farmers have historically benefited from growing more wheat than the country consumes and being able to sell excess grain to overseas markets. In crop year 2021–2022, the United States exported $7.3 billion of wheat, making it the world’s third largest wheat exporter, behind Russia and Australia.56 According to the USDA, in the early 2000s, the United States was responsible for roughly 25 percent of the world’s wheat exports, but that dominance has dwindled now to 13 percent.57 America’s share of global wheat exports has shrunk over the past 20 years as Russia has strengthened its position as the world’s wheat superpower.
Increasing international competition in wheat trading has strained U.S. wheat exports in recent years, and this trend is expected to continue. Competition from Russia, especially in African and Middle Eastern markets, poses a significant challenge.58 Russia has shown it is willing to use food trade as a tool of diplomatic force. When Bulgaria ceased transiting Russian gas to Europe, Turkey agreed to facilitate its transit in exchange for receiving wheat imports from Russia. Elsewhere, Russia sold wheat to Iran as part of a deal to help sell Iranian oil. Moscow willingly enters commodity trade markets even if it means undercutting its allies, as Iran experienced this year when Russia discounted its steel exports and grabbed Iranian market share.59 Wheat industry analysts expect Russia to continue pushing boundaries to secure access to wheat export markets, especially in regions with rapid population growth, like southeast Asia.60
Waging information warfare would be another scheme the Kremlin could employ to win in export markets. As mentioned, crafting and communicating a hoax that falsely claims American wheat supplies are contaminated with disease would cause buyers to seek alternative sources.61 Rules over grain disease quarantines can be a sensitive political subject between traders, even without misinformation campaigns. When coupled with stolen and altered data derived from a coordinated cyber intrusion, the United States would have difficulty eliminating concerns about the quality of American wheat stocks.
Complicating the issue is that prior incidents of contaminated U.S. wheat exports could strengthen Russian hoax claims. The Soviet Union and several other countries complained of dirty, rotting, and insect-ridden U.S. grain in the 1980s.62 In the mid-1990s, the USDA had to institute a regulatory program to certify wheat shipments were free of fungal disease after a Karnal bunt outbreak in the United States.63 Recent research suggests that the Environmental Protection Agency scientific integrity and transparency failures related to pesticide use have eroded global trust and are undermining U.S. agricultural exports.64
If Russia succeeds in taking global wheat export markets from the United States, American farmers will undoubtedly be threatened. With less market access and increasing input costs, the incentive for growing the preeminent American staple crop would dwindle, resulting in lower output and production capacity. Such an outcome, combined with other disruptive options identified in this essay, could accelerate Russian aims of undermining U.S. global power.
Disruption Option 4: Agricultural Bioterrorism
Another vector for attacking U.S. wheat production, and one carrying potentially the broadest impact, would be a Russian attack involving pests or pathogens designed to damage crops. Such an attack would likely be done covertly to provide plausible deniability. Before the Biological and Toxin Weapons Convention of 1972 (BWC), several countries, including the United States, developed and maintained offensive biological weapons research programs.
Many historians and scientists claim that while other signatories to the BWC ceased their offensive biological weapons programs after the convention went into effect in 1975, the Soviet Union secretly continued its program despite being a signatory to the treaty. Research has shown that the Soviet program was the longest and most sophisticated the world has ever seen, beginning in 1928 and lasting until at least 1992. Its scope was massive, involving over 65,000 workers.65 A specific component of Soviet biological warfare research operated under the code name Ekologiya and focused on developing pathogens that would kill animals and plants, including crops such as wheat. It eventually became the largest ever offensive biowarfare project focused specifically on agriculture.66
Should the Russians choose to conduct a biological attack against American grain crops, wheat rust could likely be the weapon of choice. Wheat rusts are a type of fungus belonging to the genus Puccinia that can affect different parts of the wheat plant. Also known as “the polio of agriculture,” it has been the worst wheat disease in history, capable of causing catastrophic crop failures. During the first half of the 20th century, rust destroyed one-fifth of America’s wheat crops in periodic epidemics.67 Before the BWC outlawed offensive biowarfare programs, many countries sought to weaponize wheat rust because of its potent effects in targeting crops. Relative to other biological agents, it remains viable for an extended period of time under cool storage (2 years) and spreads quickly after release.68 In addition, plant rust fungal spores are easily dispersed, durable to withstand transportation and transmission, and easy to produce in sufficient quantities. If the specific variety of targeted wheat is known, attackers could use tailored strains of wheat rust that would have the greatest likelihood of successfully killing and spreading while protecting their own crop with specific strain-resistant varieties.69
According to some claims, the Soviet program did not stockpile anti-agricultural weapons like wheat rust but maintained several facilities “equipped as mobilization capacities, to rapidly convert to weapons production should the need arise.”70 A historian of the Ekologiya program described one of the project’s main facilities as possessing the world’s largest “unique collection of fungal pathogens against wheat.”71 Another facility, the Scientific Research Agricultural Institute in Gvardeyskiy, Kazakhstan, was reportedly a key testing site for newly developed anticrop (including antiwheat) pathogens in greenhouses measuring a total area of 100 square meters.72 In total, four separate program facilities maintained laboratories focusing on rust species research.73
Project Ekologiya has several implications for the security of U.S. wheat production today. First, the Russian Federation inherited the offensive Soviet biological weapons program and its decades of research, development, and technological capability. While the Kremlin claims the program ended after the Cold War and that it has since complied with the BWC, the United States argues otherwise. In 2021, the State Department reported the following: “The United States assesses that the Russian Federation maintains an offensive BW program and is in violation of its obligation under Articles I and II of the BWC. The issue of compliance by Russia with the BWC has been of concern for many years.”74
Not only is there a possibility Russia has maintained a biological weapons program with agricultural components, but a second implication for U.S. national security is that conventional American farming is potentially vulnerable to biological attack because intensive farming, as practiced today, “involves limited diversification of crop and cultivar genetics over large areas,” helping create “an ideal environment” for new pest establishment and spread.75 As small, diversified farms have been overtaken by today’s larger farming operations for the sake of profit and efficiency, the United States has inadvertently made its crops potentially more vulnerable to biological attack. Some experts note that pests and the plant diseases they can carry would be “an ideal means of waging ‘asymmetric’ war” in scenarios that fall below the threshold of conventional armed conflict.76
Exacerbating the problem is that our germplasm seed banks are potentially insufficient in possessing the diversity required to rebound from a devastating biological event. New varieties with resistance would be essential in a successful attack scenario because wheat rust can persist over the winter and remain viable to infect the following year’s crop. During the Cold War, germplasm collections were better stocked and more robust to ensure resilience against known pathogens. Those efforts have fallen behind in recent decades.77 For example, a new strain of wheat stem rust emerged in Uganda in 1998, commonly known as Ug99.78 Since then, scientists have evaluated roughly 200,000 wheat varieties for natural resistance to Ug99. Less than 10 percent demonstrated adequate resistance.79 Not until 2017 did researchers discover a gene that provided resistance to Ug99, making it possible to develop wheat varieties naturally capable of surviving the disease.
It should be noted that debate exists around the degree of risk posed by a supposed lack of biodiversity. Some wheat pathology experts argue that concerns of insufficient biodiversity in American wheat crops are overblown. While wheat as a species is a monoculture grown in vast quantities across the United States, there are many dozens of commercial wheat varieties grown today, providing a reasonable degree of genetic diversity within the species to mitigate massive impacts from disease or pest outbreaks.80
Although fungi are the most likely form of intentional biological threat to wheat due to the relatively ease with which they can multiply and spread, other pathogens like viruses and bacteria can also affect grain crops. Defending against viruses is problematic. Treatments against viruses are generally not as effective as using chemicals to control fungi and bacteria. Disturbingly, the Soviet biowarfare program reportedly included a facility based in Uzbekistan, the Central Asian Scientific-Research Institute of Phytopathology, that “focused on viral diseases of wheat.”81 These claims are corroborated by a declassified 1977 U.S. Defense Intelligence Agency report stating that the Soviet antiplant biowarfare program conducted work on wheat and barley mosaic streak viruses.82
Another intentional wheat industry disruption scenario could involve the malicious introduction of wheat parasites that carry harmful bacteria. For example, Rathayibacter tritici is a bacterium that infects wheat via parasitic nematodes to cause a toxic gumming disease.83 While not currently present in the United States, introducing the associated nematode vectors to American wheat crops could at least result in wheat export quarantines, as trade partners would balk at accepting potentially contaminated grain shipments.84
Biological attack against wheat production could also be an attractive objective for an adversary like Russia because of the costs imposed by recovery. Pests and pathogens can disperse and reproduce at dramatic rates, providing the potential to wreak havoc across vast amounts of American farmland. For example, a small outbreak of Karnal bunt in the American Southwest in 1996 resulted in $250 million in damages.85 In Texas, the cost of mitigating effects on agriculture from nonnative fire ants is more than $1.2 billion annually. Expenses for protecting crops from a nonnative insect carrying Pierce’s Disease that has plagued California grapevines since 1989 are also substantial.86 Beyond just the recovery costs, pathogen outbreaks could also easily lead to trade embargoes as destination countries resist the risk of importing contaminated U.S. wheat. Thus, a widespread infestation damaging American wheat crops “could lead to potential economic losses of immense proportions.”87 A former member of the Soviet biological weapons program agreed, citing antiagricultural biological weapons as “particularly suitable” for disrupting a target country’s economy.88
Intentional infestations targeting agriculture for nefarious purposes are not without precedent. Analysts strongly suspect manmade causes behind a debilitating outbreak of the fungus Moniliophthor perniciosa, also known as witches’ broom disease, among cocoa fields of Bahia, Brazil, beginning in 1989.89 Potentially motivated by the perpetrator’s desire to destroy the chocolate industry to punish its wealthy landowners, the suspected attack nearly exterminated the area’s cocoa plantations over the following decade. By 2001, “Brazil went from being the world’s third-leading cocoa producer to being the 13th.”90 Given this potential for covert bioterrorism to exact large economic costs to a country’s agricultural industry, Russia could consider it as an increasingly attractive option as strategic competition with the United States escalates.
Risk is a function of likelihood and consequence and can be mathematically described as Risk = Likelihood of an Event x Consequence (loss due to the event).91 To aid in measuring likelihood and consequence of the four attack strategies Russia could employ to target U.S. wheat production, an expert survey was conducted. Data was collected from 30 participants in the United States who are professionals with expertise in fields related to the wheat industry, including farming, academia, information technology, and global trade. Due to the potential security concerns of identifying the experts in the survey, it was decided that all participants would remain anonymous. The survey asked each participant to assess the likelihood and consequences of the four Russian disruption scenarios: cyber attacks targeting grain infrastructure, restricting fertilizer exports, undercutting U.S. wheat exports, and agricultural bioterrorism.92 Participants assessed the likelihood of each scenario using a 5-point Likert scale converted to the following percentages to enable calculations (table 2). Participants assessed consequence using the following 5-point Likert scale based on expected economic losses ranging from less than $1 million to more than $20 billion (table 3). Survey results for likelihood and consequence are captured in figures 3 and 4 and risk scores are presented in figure 5. Calculated mean scores for likelihood and consequence for each attack scenario are found in table 4.
Further refinement of the results was conducted to ultimately generate a more robust measurement of overall risk for each scenario. To calculate an overall likelihood percentage, the sum of response percentage values (as shown in table 2) was divided by the total available percentage of all responses. To calculate the dollar value associated with the overall consequence score, the mean score for each scenario was assessed as a percentile within the associated dollar range (as shown in table 3).
To then calculate the final risk for each scenario, the calculated likelihood percentage was multiplied by the consequence dollar value to determine the overall amount of risk in terms of dollar cost, as shown in table 5.
Limitations in this study include those intrinsic to Likert scale surveys (for example, not able to capture all opinions, subjective results, etc.) and the small sample size of expert participants. Another limitation of this study is the inherent biases of the participants who come from a range of professional backgrounds related to the wheat industry. Therefore, deeper analysis is needed to provide more robust risk measurements of wheat industry disruption scenarios. Still, results from this survey point to potential prioritization in policy considerations to address the threat of potential Russian disruption of the U.S. wheat industry.
The United States must act to ensure resilience of domestic wheat production, storage, and transportation to mitigate the risks outlined above. First, additional research is needed to measure domestic food security risks more accurately. A Likert survey of experts like the one conducted in this study that encompasses a greater number of experts and uses finer granularity in the scales would be beneficial. A Delphi study could also serve to identify a stronger consensus of risk to the U.S. wheat industry from potential Russian action.93 Beyond improving the survey, policymakers and wheat industry leaders should consider the following measures, which are listed in prioritized order to address risks from highest to lowest based on the expert survey results shared above.
USDA: Proactively Defend Against Biological Warfare Targeting Crops by Ensuring Sufficient Genetic Diversity of American Grains. Industrial wheat breeding has helped increase yields over the past century, but some argue that this has come at the expense of genetic diversity: “Modern breeding techniques narrowed the genetic base of germplasm used to develop varieties for cultivation.”94 Genetic uniformity in modern wheat crops means greater potential vulnerability to new pathogens. Ensuring a source of genetic variation in wheat is essential for disease resistance. Landrace wheats play a vital role in doing so. Landraces are premodern grains that developed naturally over millennia while adapting to local environmental conditions. Many landraces were lost during the 20th century as farmers abandoned them in favor of modern varieties championed in the Green Revolution.95 Due to their wide variety, landraces do not possess the genetic bottleneck of modern hybrid wheats.
Landraces typically produce yields lower than modern wheats, which can seemingly put them at odds with rising global food demands. Nevertheless, they serve a critical role in preserving genetic diversity to ensure American wheat crop resilience should new pathogens wreak havoc on modern varieties. It is also worth noting that landrace wheats are reported to have better yields and higher quality attributes than modern varieties “under organic and low-input farming systems.”96
Landraces can and have been preserved in seed banks, which is worthwhile, but there are limitations in preserving them this way. Landraces are heterogeneous, meaning that individual specimens of the plant’s spikes stored in banks do not necessarily possess all the genetic diversity in the landrace variety. In addition, most biologists agree that active cultivation of landraces is essential to preserve cultivation knowledge.97 Given these circumstances, USDA should find ways to collaborate with American farmers and researchers to incentivize and ensure sufficient production levels of landrace wheats.
USDA and DHS: Prepare for Adequate Response to Biological Attack Against U.S. Wheat Crops. USDA–National Institute of Food and Agriculture and the Department of Homeland Security established the National Plant Diagnostic Network (NPDN) during growing fears of bioterrorism following 9/11 and the 2001 anthrax attacks.98 The NPDN serves as a network of diagnostics laboratories across the country that help rapidly identify plant disease and pest outbreaks. Since its establishment, funding and support for the NPDN have begun to erode.99 As the original sponsoring agencies, USDA and DHS should evaluate the current state of the program to make sure its capabilities are sufficiently resourced to perform adequate early monitoring and detection of a biological attack against domestic crops.
In addition to shoring up early warning capabilities, USDA should also review the agriculture industry’s preparedness to respond to bioterrorism. If an outbreak of disease against U.S. wheat crops occurs, agrochemical suppliers will need to deliver treatments to limit damage. However, supply chains for pesticides can be brittle, as was the case during the COVID-19 pandemic.100 Further analysis of domestic pesticide treatment inventories and supply chains would help identify what is needed to boost the resilience of U.S. farms in a worst-case scenario.
USDA: Pursue and Encourage Alternatives to Conventional Fertilizer. The American wheat industry’s reliance on conventional fertilizer has become increasingly challenging due to rising prices, global supply disruptions, and environmental costs. Greater emphasis is needed on adopting renewable fertilizers. While multiple solutions may be required to fill the gap, transitioning American agriculture to a more sustainable and regenerative approach is key.101 The Biden administration has tried moving on this front and recently announced $500 million in funding for boosting domestic fertilizer production that is “independent, innovative, and sustainable.”102 This effort is worthwhile to help transition the United States off foreign fertilizer dependence. It does not, however, preclude the need to continue transitioning to more sustainable and regenerative agriculture.
One facet of sustainable agriculture that would help provide a viable alternative to synthetic fertilizers is the greater use of cover crops. Growing the same monoculture crop in the same field for years on end, as most conventional U.S. farmers do, damages the soil microbiome as the same nutrients are depleted over time. Conventional agriculture deals with this problem by applying large amounts of synthetic fertilizer to the soil. When cover crops are added to crop rotation, the cover crop plants naturally fertilize and rejuvenate soil health. Furthermore, a growing body of scientific research shows that yields from sustainable agricultural systems are comparable to that of conventional systems.103
The downside to cover crops is the inability to grow a desired crop (for example, wheat) for that growing season, which would reduce overall American wheat output. Options exist to compensate for drops in annual grain yields that would result from the broader use of cover crops. Addressing all options is beyond the scope of this essay, but one example is choosing cover crops that can act as cash crops that produce food and simultaneously amend the soil. An example of this would be cover crop legumes, which fix nitrogen to the soil that would be available for the next season’s wheat.
Funding is another limiting factor and will be necessary to incentivize American farmers to widely adopt the use of cover crops. Sustainable agriculture receives little government funding compared to industrial agriculture. The most recent Farm Bill (a package of legislation Congress passes every 5 years to support U.S. agriculture) provided less than 7 percent of its funding for conservation practices.104 USDA can increase funding for cover crop implementation by reducing Farm Bill spending in other areas overdue for adjustment, like conventional corn subsidies.105
USDA: Establish a National Strategic Grain Reserve. As previously noted, if Russia succeeded in some capacity to disrupt U.S. wheat production, resulting in domestic grain shortages, no current national wheat reserve exists to reduce the ensuing effects. Given how essential grain is to the U.S. food supply and the increasing probability of climate change’s impact on global grain production, a strategic grain reserve makes sense. The need for a reserve has risen in recent times. For instance, droughts in 2012 affected corn production to such an extent that the United States had to import corn from Brazil, a surprising development for America as the world’s leading corn producer.106 Converting any remaining funds within the Bill Emerson Humanitarian Trust into a physical grain reserve and supplementing it by redirecting funding from conventional commodity crop subsidies could provide this much-needed resilience in our national food security.
State and Commerce Departments: Encourage Import-Dependent Countries to Boost Domestic Food Production to Minimize Exposure to Russian Grain Trade Manipulation. Having export markets available to American wheat not only can be lucrative for farmers and commodity traders but also can undermine efforts in those destination countries to develop greater self-sufficiency in food production. The United States will always need to produce more wheat than it consumes on average because this helps buffer against the effects of unforeseen production shortfalls regardless of the cause. It also assists trade partners in meeting their food requirements when they experience unexpected shortages or find themselves in positions where they cannot realistically become fully self-sufficient in their own food production. However, in a world where Russia is a global food power and can use inputs and commodities as weapons to win concessions, allies and partners should be encouraged to reduce their dependence on foreign food sources. Although this could reduce U.S. wheat exports in the long run, it would, more importantly, mitigate Russia’s ability to exploit vulnerable countries to enhance their Great Power status.
DHS: Harden Information and Operational Technology Networks Used for Grain Production, Storage, and Transportation. Cyber security remains a challenge for organizations across all industries, but implications for breaches to critical infrastructure networks such as those in the grain industry are more severe and require greater attention to ensure proper security practices. For wheat industry organizations’ information technology and operational technology networks, like other industries, known best practices provide the greatest defense against cyber attacks. However, many businesses fail to implement the full range of best practices due to limitations in understanding and the failure of company executives to invest appropriately in network defense.
Wheat industry leaders can leverage the National Institute of Standards and Technology cyber-security framework for guidance.107 Taking this proactive approach to network defense will limit exposure to disruptive intrusions like the ransomware attacks that recently plagued Midwestern grain elevators.
As a rival in strategic competition and as the emerging food superpower, Russia is uniquely positioned to disrupt U.S. wheat production, storage, and delivery. Moscow has already demonstrated its intentions to attack U.S. interests in adversarial competition at levels below armed conflict, and future attempts to do so could realistically involve targeting the American wheat industry. As the most important food staple in America, wheat supply degradation could have significant consequences for domestic food security and, by extension, trust in the U.S. Government. Should Russia pursue such a strategy, its tactics could range from cyber attacks on grain infrastructure to manipulating global fertilizer and wheat export markets to covert antiagriculture biowarfare.
To mitigate these threats, American policymakers should consider a range of policy options. First, further research is needed to measure risks of Russian disruption to the U.S. wheat industry. Results would more accurately prioritize policy considerations. In the meantime, prioritized policy considerations should include:
- improving biodiversity in U.S. wheat production
- ensuring sufficient resourcing for detection and response to a biological attack against U.S. crops
- enhancing sustainable agriculture to reduce dependence on imported fertilizer
- establishing a national grain reserve
- reducing global exposure to Russian grain trade manipulation
- encouraging the improved implementation of cyber security best practices throughout the wheat industry.
With an increased focus on reducing food system vulnerabilities, U.S. leaders and the world’s citizens can reap a harvest of improved global security.

Known to be toxic for a century, lead still poisons thousands of Midwestern kids
When the pediatrician recommended Lisa Pascoe have her then-toddler tested for lead poisoning, she thought there was no way he could be at risk. Everything in her St. Louis, Mo., home had been remodeled.
But then the nurse called to say her son's blood lead level was dangerously high — five times the level federal health officials then deemed elevated.
Pascoe said she was "completely shocked."
"After you hang up on the phone, you kind of go through this process of 'Oh my gosh, my kid is lead poisoned. What does that mean? What do I do?'" she said.
That same week, St. Louis city health workers came out to test the home to identify the source of the lead.
The culprit? The paint on the home's front window. Friction caused by opening and closing the window caused lead dust to collect in the mulch and soil outside of the house, right where her son played every day.
A decade later, the psychological scars remain. Pascoe and her toddler ended up leaving their home to escape lead hazards. To this day, she's extra cautious about making sure her son, now a preteen, and her two-year-old daughter aren't exposed to lead so she doesn't have to relive the nightmare.
Pascoe's son was one of almost 4,700 Missouri children with dangerous levels of lead in their blood in the state's 2012 report — decades after the U.S. started phasing lead out of gasoline and banned it in new residential paint and water pipes. Missouri's lead-poisoning reports run from July through June. Though cases have fallen precipitously since the mid-20th century, lead is a persistent poison that impacts thousands of families each year, particularly low-income communities and families of color.
Eradicating it has been a decades-long battle.
No safe level
Omaha, Neb., has been cleaning up contaminated soil from two smelters for more than 20 years. The Argentine neighborhood of what is now Kansas City, Kan., grew up around a smelter that produced tens of thousands of tons of lead, as well as silver and zinc. About 60% of homes in Iowa were built before 1960, when residential lead-based paint was still used. Missouri is the number one producer of lead in the United States.
The four states have some of the most lead water pipes per capita in the country. While representative data on the prevalence of lead poisoning is hard to come by because screening rates lag in many areas, one study published last year found that the four states struggled with some of the highest rates of lead poisoning.
Over the next few months, the Missouri Independent and NPR's Midwest Newsroom are collaborating to investigate high levels of lead in children of Iowa, Kansas, Missouri and Nebraska. By analyzing scientific research, delving into state and local data, and interviewing parents, experts and advocates from across the country, the project will shed light on a public health disaster that continues to poison children every year.
"We know that there is no safe level, that even at really low levels, it can affect intellectual growth, cognitive development. And we can prevent that type of harm," said Elizabeth Friedman, a physician and director of the Pediatric Environmental Health Specialty Unit for Kansas, Missouri, Nebraska and Iowa. "So why wouldn't we?"
David Cwiertny, director of the Center for Health Effects of Environmental Contamination at the University of Iowa, said it's "unacceptable" for anyone to be exposed to lead.
"We should go to the ends of the Earth to invest in staff and prevent it from happening if we can," Cwiertny said.
At Pascoe's home, workers encapsulated the flaking paint and replaced the top layer of tainted soil outside the home. During encapsulation, lead paint is coated and sealed to prevent the release of lead dust or paint chips. Her toddler's blood lead level began to drop from its high of 25 micrograms per deciliter.
But that wasn't enough to keep his lead level low.
Even though Pascoe kept her son from playing outside, cleaned regularly with a vacuum cleaner equipped with a HEPA filter provided by the health department, and wiped off everything that could track lead dust into the home — from shoes to the family dog's feet — her son's level hovered at six micrograms per deciliter for nearly a year.
In 2013, Pascoe and her son moved out of the city and into a home without lead in St. Louis County. Finally, his levels dropped to below one.
An invisible toxin
Lead is a dangerous neurotoxin commonly used in water pipes, paint, gasoline and household products until the late 20th century, decades after scientists began sounding the alarm about its danger.
In high doses, lead can be fatal. Women in the 19th century used it to induce abortions and sometimes ended up poisoning themselves. Children who are lead poisoned now, however, have much lower levels and don't show blatant or immediate symptoms.
Even after the source of the exposure is eliminated, long-term effects of the toxin linger.
Officials with the World Health Organization warn there is no safe level of lead in blood. Even levels as low as five micrograms per deciliter can cause behavioral difficulties and learning problems in children.
Lead-poisoned children may have trouble with language processing, memory, attention and impulsivity, said Dr. Justina Yohannan, a licensed psychologist based in Atlanta. Many require special education services in school.
Now in sixth grade, Pascoe's son has been diagnosed with autism and ADHD.
The Centers for Disease Control and Prevention last year updated its blood lead reference value to 3.5 micrograms per deciliter from five. The reference value represents the 2.5% of children with the most elevated blood lead levels who should be prioritized for investigations and resources. It's not a health standard, and CDC leaves it to the state and local authorities to determine at what levels they will take action depending on state laws, local ordinances and the resources they have available.
The Healthy Homes program in St. Louis County, where Pascoe now lives with her husband, Daniel Pascoe, only follows up with a home inspection if a child's blood lead level exceeds 10 micrograms per deciliter, unless a family makes a request for an assessment below that level. The city of St. Louis separated from St. Louis County in the late 19th century and operates as a separate local government.
Follow-up on lower levels of exposure is focused mostly on educating parents and families about the risks and dangers of lead.
For higher levels of exposure, health workers use an X-ray fluorescence analyzer during assessments to test components of the home for lead.
"The most common source of lead exposure in the county is lead-based paint. So the majority of the time, that's our main focus," said Tammi Holmes, supervisor of the Healthy Homes program.
"We're looking for anything that's original to the house — original windows, original doors, door casings, things like that, that may have lead-based paint on them."
Pascoe said she never saw her son eat lead paint chips. And while lead poisoning due to consumption of paint chips is fairly common, Holmes said it's not always a factor.
"A lot of times people think that the only way kids are exposed is just by eating and ingesting lead-based paint," Holmes said. "But that's not always the case. The main route of exposure a lot of times is inhalation, and it's the dust."
Lead poisoning disproportionately affects Black children and kids in low-income neighborhoods.
In predominantly Black neighborhoods of north St. Louis, across town from Pascoe's old home, children suffer some of the highest rates of lead poisoning in the city. Black children in Missouri are nearly twice as likely to suffer lead poisoning as their white peers.
"And this has happened because of the racist historical practices and policies that continue to segregate children and families of color into older, sometimes less-maintained, overburdened and under-resourced neighborhoods where lead exposures are more common," Friedman said.
Philip Landrigan, a lead researcher for 50 years, did research and testing near an enormous smelter in Kellogg, Idaho, in the early 1970s.
"And the doctor who was the doctor for the lead company ... told me one time in a meeting that the only kids in Kellogg, Idaho, who got lead poisoning are 'the dumb and the dirty,'" Landrigan said. "Even though that was 50 years ago, that line of thinking is still alive and well."
While many cities have grants or loans available to help remediate homes, low-income families in rental housing don't always have the final say.
Amy Roberts, who runs the lead-poisoning prevention program in Kansas City, Mo., said landlords are often cooperative and allow for repairs when their tenants' children are lead poisoned. But not always.
"Sometimes we get pushback from landlords who don't want to do it, or they'll do a little bit, or they'll just take a long time," Roberts said. "Or they'll evict the family."
It's illegal to evict a family because of lead exposure. But if a landlord has cause to evict a family that they haven't acted on, they might do so rather than deal with the health department coming in, Roberts said.
"They'll say, 'Well, we didn't evict them because of the lead. We evicted them because they were behind on their rent,'" Roberts said. "And so would they have allowed them to stay if we hadn't gotten involved because of the lead? It's hard to know."
In Omaha, where an old lead smelter left behind contamination of over 27 square miles centered around downtown, local ordinances have more teeth. Naudia McCracken, the lead program supervisor for Douglas County, Neb., said landlords are required to repair any lead hazards.
"There's no ifs, buts, maybes," McCracken said. "They have to fix it."
While Omaha has struggled with contamination brought on by the smelters, she said that legacy has allowed the county and city to be more aggressive in remediating contamination and preventing lead poisoning.
Omaha provides a home inspection to any family with a child whose blood lead level is greater than 3.5 micrograms per deciliter. And the city provides inspections to families in any house built before 1978.
Speaking only for herself, McCracken said she'd like to see more money go into removing lead paint and improving housing nationwide.
"In the majority of the country, in the way that the programs are, we're waiting for there to be a child with (an elevated) lead level for action to take place," she said. "And I think that's kind of backward."
An overdue conversation
The water crisis in Flint, Mich., shone a light on the devastating effects of lead. Scientists' conclusion there is no safe level of lead and President Joe Biden's pledge to remove the estimated 10 million water service lines underground add momentum toward finally eradicating the metal.
Bruce Lanphear, a longtime lead researcher and professor at Simon Fraser University in Vancouver, said the U.S. has typically made progress on lead when crises or new research galvanized public support. But regulations and action to clean up lead contamination often depend on what is considered feasible.
Cwiertny noted the issue of lead poisoning through drinking water had risen in prominence following crises.
"The concern I have is people — through the rhetoric of politicians talking about what great progress we're making by getting $15 billion here and allocating recovery funds there to address this — will think it's a problem that gets solved and there won't be any accountability," Cwiertny said.
By the time the U.S. started phasing lead out of gasoline, banned it in residential paint in the 1970s and outlawed lead water pipes in 1986, scientists had been warning of the dangers of lead for decades.
In 1925, as use of lead in gasoline gained momentum, Yandell Henderson, a professor at Yale University, told a gathering of engineers that it would slowly poison vast numbers of Americans.
"He said that if a man had his choice between the two diseases, he would choose tuberculosis rather than lead poisoning," the New York Times wrote at the time.
A concerted effort by the lead industry staved off regulations, Lanphear said.
Lanphear said he was invited to speak to Omaha residents 20 years ago about lead poisoning. At the end, he took questions.
"There was this big burly guy with a flannel shirt, beard (who) got up — trucker's hat — and he got teary and he said, 'I worked at the smelter for years, and every morning, I was ordered to reverse the flow and discharge all the contaminants that they had scrubbed out during the day.'"
There are stories that "just break your heart" showing how flawed regulation was, Lanphear said, and how "irresponsible" the industry was.
The legacy of the lead is well documented among adults who grew up surrounded by the metal.
Forty years ago, more than 90% of children had blood lead levels above 10 micrograms per deciliter, almost triple the Centers for Disease Control and Prevention's new reference value.
Researchers estimated last month that just over half of Americans alive today were exposed to high lead levels as children, especially those born between 1951 and 1980. On average, lead cost those people 2.6 IQ points.
Childhood exposure to the metal causes a 70% increase in the risk of cardiovascular disease mortality.
"But it was largely overlooked, largely forgotten," Lanphear said. "All of the focus was on lifestyle choices, which was convenient. Industry didn't have to do anything. Government didn't have to change regulations."
Acute lead poisoning results in noticeable symptoms, including loss of appetite, constipation and stomach pain, fatigue and a blue tinge around the gums.
But lead poisoning now is nearly always chronic, low-level poisoning that may not show obvious symptoms. It can manifest later in behavioral challenges, lowered IQ and increased risk of cardiovascular disease.
Scientists in the second half of the 20th century started documenting links between low-level lead poisoning and lowered IQs. In the early 1970s, there were children with lead levels above 40 micrograms per deciliter who experienced convulsions and comas, Landrigan said. Some children died of lead poisoning at that time.
Before 1970, blood lead levels were considered elevated above 60 micrograms per deciliter. The surgeon general reduced that to 40 in 1970. The CDC reduced it to 30 in 1978; 25 in 1985; 10 in 1991; five in 2012; and 3.5 last year.
"So we were really breaking new ground when we tested those children around the El Paso smelter and the Kellogg, Idaho, smelter and determined that children with no obvious symptoms had reduced IQs and slow reflexes," Landrigan said.
Lanphear said it was difficult for researchers to come to grips with the fact that they had all been exposed to dangerous levels of lead when they were children.
"So there was sort of this disbelief, and I think that happened almost at every level," he said. "How could it be that in the '70s, virtually, by today's standards, all kids were lead poisoned?"
The Pascoes are vigilant about researching the products the family uses now. Their two-year-old daughter only uses toys and crayons that are lead-free, and the family eats from glass dishes to avoid contact with lead that could leach into food from ceramic plates and bowls.
Lisa avoids wearing jewelry her toddler might put in her mouth and doesn't visit older or recently renovated homes that could contain lead hazards.
Other parents are often shocked when Pascoe tells them about her son's lead poisoning.
"Some people probably think kind of like I did initially. Like, 'Oh well, that will never happen to me,'" she said. "Well that happened to my son and we weren't thinking it could happen to him at all."
She warns other families, especially in older houses, to get a home lead assessment.
"I thought it was a thing of the past," she said, "that lead poisoning had just been something I'd heard about in the '90s."
Parents often blame themselves for their children's lead poisoning, Lanphear said. And there are steps families can take to avoid lead and other contaminants: adding landscaping to bare soil, dusting surfaces, avoiding plastic and canned foods. But he said it's primarily up to federal health officials.
Once, Lanphear said, he was being interviewed for a book. The author asked him about his own family.
"He says, 'You do this for a living, right?'
I said yes.
'You have kids.'
'Can you protect your own children?'

Social determinant of health.
Oak Valley is the principal organization of a backward reserved community called Maralinga Tjarutja Aboriginal Council (AC) Local Government Area (LGA), South Australia. The general population varies, yet a year’s review definite around 128 people, for the most part-Aboriginal. It is approximately 128 kilometres (80 mi) NNW of the main Maralinga region. As the name suggests, the area is occupied with desert oak trees. The Great Victoria Desert surrounds the valley lying at the southern edge.
It was developed in 1984 withholds gave as compensation to the dispossession of the Maralinga people from their properties following the British nuclear tests which happened some place in the scope of 1956 and 1963. The perils related to living in a domain contaminated by plutonium, even after the cleanup has been a basic concern.
During the 1950s, seven bombs were tried at Maralinga in the south-west Australian outback. The consolidated power of the weapons multiplied that of the bomb dropped on the Japanese city of Hiroshima in World War Two. Some revealed the blazes of the impacts being brilliant to such an extent that they could see the bones of their fingers, similar to x-beams as they squeezed against their appearances. The greater part a century on, the vast majority here still view Maralinga as a dim section in British Australian history.
The Department of Health is welcoming entries from associations and people and social determinants of Indigenous and Aboriginal people’s wellbeing.
Health results for people are the consequence of a perplexing association between natural components and the social and social conditions which shape individuals' lives. These work as the two boundaries and empowering influences on wellbeing and social and passionate prosperity.
Somewhere in the range of 32% and one section belonging to the prosperity gap among Indigenous Australians and non-Indigenous people is inferable from contrasts in social determinants of prosperity (Indigenous as well as Torres Strait Islander Health Performance Framework 2014). This suggests a huge aspect of the work to improve prosperity uneven characters and variations lies past the prosperity division. These determinants incorporate (yet are not restricted to) - Association with family, network, nation, language and culture, Bigotry, Youth advancement, training and youth, Business and pay, Lodging, condition and framework, Collaboration with government frameworks and higher administrations, Legal implications, health benefits, Food safety.
Upgrades have been picked up in Indigenous wellbeing, however, we are not shutting the hole – the time has come to turn consideration past wellbeing determinants as we make the following stride on our excursion. Improving the medical care framework to give sufficient consideration when individuals are unwell is basic; however, does little to keep them from getting unwell in any case. Significant reasons for death and infection, for example, coronary illness, diabetes or malignant growth have their birthplaces in the early long stretches of life, in continuous and combined social and social stressors. The connects to social causes are even more clear when taking a gander at sudden passing because of injury, harming and self-destruction. We could speak more about the issues; however, we'd preferably talk about arrangements. The criticism we get from these online entries will help to: distinguish explicit activities right now giving great results to Indigenous people group and think about alternatives for more extensive usage; recognize need territories for consideration intending to the social determinants of Aboriginal and Torres Strait Islander’s health; recognize expected changes and holes in Commonwealth strategy and projects pointed toward lessening the incongruities in the field of prosperity and medical care among Indigenous individuals and non-Indigenous individuals; think about choices to improve levels of coordination and cooperation of existing endeavours at the neighbourhood, state and Commonwealth level. This data will assist us with recognizing activities that are having a positive effect and consider ways we can draw on these models, to improve coordination and joint effort among government and non-government organizations at the neighbourhood, state/an area and Commonwealth levels. Entries will be thought of and might be cited or referred to as a major aspect of a plan on the Socio-cultural Determinants of Indigenous Health. This would take care of the future cycles of the Implementation Plan for the National Aboriginal and Torres Strait Islander Health Plan of the year 2018-2023.
Bias or racial discrimination is the major reason that allows the decline of an individual’s mental and physical state of wellbeing. In the review of the year 2003, 53 evaluations in the US observed that the mental health of children and young adults of the backward and exploited community has been deteriorating. Eight out of eleven evaluations found associations between the increased cases of hypertension in the Afro-Americans along with racism. Very few assessments are carried on the effect of bias on the quality of Indigenous people in Australia, in spite of the way that masters agree that an association with the US considers is normal. Western Australian Aboriginal Child Health Survey 2001-02 (WAACHS) is one such examination. It detailed than 22% of the Aboriginal kids under the age of 12 suffered from racial discrimination in the past a half year. This was related to excessive smoking, marijuana use and liquor utilization in the under-age kids.
Racism gives rise to issues related to mental health. Kids and even adults may face significant issues with racism. It humiliates the person to the core. It could depress the individual clinically. It harms the person first mentally and their mental state begins to take a toll over their physical health as well. Depression and under confidence may lead to extreme introvert attitude resulting in a decline in the intelligent quotient. Individuals may get addicted to drugs for escaping reality and suffer serious health issues. Children and adults indulge themselves heinous crimes. They get involved in criminal activities end up their entire lives behind the act of laws.
It has been stated and observed that the indigenous community as a whole is progressing while, there is still the most number of segments, the government must work upon to improve their health-related issues. Every 2 out of 5 individuals are mentally depressed or unpleasant. This makes the entire society vulnerable and a possible victim of their nourishment.
The physicians and professionals too fail to give the indigenous community people their share of honour and respect. Thus, the community individuals get racially harassed and discriminated in the workplace and at the hospitals. This makes them shut to themselves and the disclosure to any disease or health problem is usually untold.
The National Health and Medical Research Council (NHMRC) is one of Australia's pinnacle bodies that help wellbeing and clinical examination; create wellbeing guidance for the Australian people group, wellbeing experts, and governments; and give exhortation on moral conduct in medical care and in the direction of wellbeing and clinical exploration. One of NHMRC's previous activities was a distribution entitled Cultural Competency in Health: A guide for strategy, associations and cooperation. This guide advanced the instructing of social skill for all wellbeing experts despite the fact that unmistakably wellbeing proficient training had not embraced the suggestions longer than 10 years after the fact. As most, if not all, wellbeing callings require a four-year certification that prompts enlistment, Universities Australia (UA) made an approach for tertiary organizations, planning to diminish wellbeing variations by inserting competency-based educational program.
New awareness campaigns must be exercised. The government must urge the need to rule out the possibility of any racial discrimination and lead to a better environment. The campaign must focus the issues and problems faced by the community and bring the reality to ground.
Better health sessions must be provided to the community people for better assistance. The health staff must be trained and educated more ethically and take strict actions against racism. Psychological counselling and health therapies must be provided to young adults and every needy individual who has ever suffered racism and has undergone depression or any kind of mental issue.
Mental Heath should be considered to be an important issue amongst the population. The Indigenous Australians have suffered discrimination on the basis of caste, creed, color, and other socio-cultural differences. The individuals belonging to the Oak Valley, suffered racists behaviour from the other non-Indigenous people for a prolonged period deteriorating their mental status. The nuclear explosion of the 1950s not only devastated the former living population but also impacted the upcoming generations grossly. Addressing Mental Health must be considered a vital concern. Campaigns for spreading awareness must be carried out. This would not only spread awareness but also provide a platform to the patients and the victims to get counselling. Children and young adults must be monitored properly to hold them from falling prey to any addiction or false practices.

This is a summary of UK Copyright law highlighting the points you may need to know:
Within this page
- What is copyright?
- Copyright and Intellectual Property
- What is protected?
- How long does copyright last?
- When can copyright material be copied?
- What does Fair dealing mean?
- Non commercial research and private study
- Instruction and examinations

Copyright is the legal protection given to a piece of original work as soon as it is fixed in some form, such as written or drawn on paper, in an audio recording, on film, or recorded electronically. It is a form of limited monopoly which benefits the copyright owner. Usually the first owner is the person who created the work. If the work is created in the usual course of the author's employment then copyright may belong to the employer. Copyright is a limited monopoly designed to protect creators of original work.
The creator of the work owns the exclusive right to make copies of their own work and issue them to the public. If you infringe that right by copying or publishing a protected work without permission you could be sued for damages. The law also restricts making copyright works available to the public - such as via the internet. Criminal charges can result from serious or large scale infringement.
There are further acts which are restricted. If you wish to adapt a copyright work, for example by translating it or writing a dramatised version then you also need permission from the copyright owner. The same is true if you wish to stage a performance of a play which is still in copyright.
The showing of films and playing of music (or other protected sound recordings) in a public context also require permission from the copyright owners.
In the UK copyright arises automatically once a work is fixed. There is no registration procedure. To enjoy copyright protection the work must be original, that is to say it must be your work, not copied from someone else.
Copyright is also a commodity which can be sold, licensed or left in your will in the same way as other forms of property. If you transfer it to someone else you are said to "assign" your copyright and that requires a written agreement.
There is no copyright in ideas, only in the way those ideas are expressed. If you were to publish a paper describing the theories of someone else but entirely in your own words then it is unlikely to be copyright infringement although it may be plagiarism.
The legal framework is laid out in the Copyright, Designs and Patents Act 1988 Although updated, the linked version may not always include the most recent amendments to the Act.
Copyright is one of a family of intellectual property rights (IPR). Other examples are patents, trademarks and design rights. The website of the Intellectual Property Office (UK IPO) includes an explanation of each type of IPR.
The categories of material protected by copyright as they appear in the legislation may seem dated. However works in modern, digital formats have been assimilated into the traditional categories and are certainly protected.
Literary, dramatic, musical works
Literary works are defined as anything which is written, spoken or sung and include among other things published books, poetry, blog posts, diary entries, tables, compilations, computer programs and databases. Dramatic works include plays and works of dance or mime.
This is a wide category, including paintings, photographs, maps, charts, plans, engravings, sculpture, art installations, buildings and models of buildings.
Sound recordings, films, broadcasts or cable programmes
Sound recordings include spoken word material. Films include any kind of video recording. The soundtrack is treated as part of the film.
Typographical arrangements of published editions
This means the way the words are arranged on the pages of a literary, dramatic or musical work. The copyright in a typographical arrangement usually belongs to the publisher of the particular edition and it arises even if the work itself is out of copyright.
Web sites and online content
Content on web sites is also protected by copyright although this may not be clearly stated on the site. In terms of copyright law a piece of writing on a web site is a "literary work", an image (a photograph or a drawing for example) is an "artistic work" and a video on YouTube is a "film".
In order to copy or reuse web content you need either direct permission from the copyright owner or the benefit of a licence or a copyright exception, just as you would for material in any other format. Sometimes web sites carry their own copyright information, often in a footer. Sometimes the site or an item of content will carry a Creative Commons Licence, which defines what you are permitted to do with the content without seeking further permission.
The length of time during which a work is protected depends on its type.
- Literary, dramatic, musical or artistic works are protected for 70 years after the death of the author. By way of example, the published works of an author who died during 1950 will not come out of copyright until January 2021.
- Films are protected for 70 years after the death of the last to die of the director, author of the screenplay/dialogue or composer of the soundtrack.
- Sound recordings are protected for 70 years from the year of publication (release). If they have not been released or publicly performed they are protected for 50 years from the end of the year in which they were made.
- Typographical arrangements are protected for 25 years after the end of the year in which the edition was published.
- Uppublished works created before 1989 commonly have a copyright term which expires at the end of 2039.
Copying material that is protected by copyright usually requires the permission of the copyright owner. Obtaining permission directly from the owner is the most certain way of ensuring that your reuse of a copyright work is legal, but there are other possibilities.
In some very specific circumstances you can copy without permission under the exceptions to copyright contained in the legislation. The most important of these are fair dealing exceptions, although there are other exceptions under the legislation which are also relevant to UCL.
You need to be sure that the exception really does apply before relying upon it. Questions to ask:
Is this particular exception intended to cover what I want to do with this work?
Does the way I plan to reuse this work pass the "Fair dealing" test? This question must always be examined in the context of the specific exception. More about this in the following paragraph.
There is no concise legal definition. "Fair Dealing" depends on the context and on the relevant exception to copyright. Guidance from the UK Intellectual Property Office states that the key question is "How would a fair minded and honest person have dealt with the work?" Important questions to consider are:
Could the economic interests (or other interests) of the copyright owner be damaged by our use of the work? Is it a substitute for purchase, for example, or will we be competing with the original work?
Are we using a greater proportion of the work than is reasonable and appropriate in the circumstances?
It is also vital to credit the author and source of any work which you use. Fair dealing should not be confused with the broader US concept of "fair use" which is not relevant in the UK.
These are some of the more important fair dealing exceptions:
The exception for fair dealing for the purpose of non commercial research and private study allows you, as an individual, to make copies for the purposes of your own private study. Only a single copy of each extract is permitted and it must not be shared with others.
The amount that can be copied under fair dealing is not generally specified but reasonable limits must be applied in the particular circumstances. A good rule of thumb is a maximum of one article from a journal issue or a maximum of 5% from a book.
Anyone using a library photocopier or downloading an extract from the internet for personal use (unless under the terms of a licence) is relying upon this exception and should therefore take care to be compliant.
For example: as a student you may make a photocopy or scan a book chapter that you need to read for an assignment. You may only use this copy yourself and it should not be passed on to others.
The Act permits copying of extracts for the purpose of "illustration for instruction" and for examination by way of setting questions, communicating the questions to candidates or answering the questions. The emphasis on "instruction" makes it clear that this exception can be used to copy material for use specifically in a teaching context, as long as it is fair dealing.
This would not cover the use of the same material for other purposes such as longer term storage in a virtual learning environment for retrieval on demand although temporary storage on a secure VLE as part of the instructional process may be covered.
Copyright material in any medium, including for example film and sound recordings are within the scope of this exception. The instruction must be "non commercial". It follows that using this exception in the context of fee charging CPD courses would not be appropriate.
For example: you may wish to include images from printed sources within your thesis or dissertation for examination purposes. This is permitted under the exception, as long as it is fair dealing. Copyright issues will arise however if your thesis is then made available online or published, since that is a diferent context and the examination exception would no longer apply.
Copying certain material may be acceptable for purposes of submitting your thesis for examination, but reproducing the same material for publication would not be covered by the exception for instruction and examination. Unless it is covered by a different exception, you will need to ask the copyright owner's permission.
Please refer to our e-Theses pages for further information on this.
This fair dealing exception permits quotation of limited extracts from copyright works of all kinds in any context as long as the use of the quoted material can be defended as fair dealing. It is always advisable to keep the extracts which you quote as short as possible.
Although this exception is very wide ranging, you must be sure that your use of the quotation will pass the fair dealing test. Otherwise you may be infringing the copyright in the original work. The author and source should always be properly acknowledged.
This exception should be used with great caution in any context which could be thought of as "commercial". It is safer to seek permission from the copyright owner in those circumstances.
This exception allows copyright works to be copied into an accessible format for individuals with disabilities or for the benefit of persons with disabilities generally. This applies to any disability which limits access to copyright works and is to be found in Sections 31A and 31B of the Act.
This covers all types of copyright work. For example it would cover copying a text into a large print version, adding subtitles to a film or copying text into a format which is more accessible for persons with dyslexia.
The main limitation is that if a version in the required format is already available on reasonable terms then we should buy that rather than make a copy. This is not a fair dealing exception and is not subject to that test. The whole of the work may be copied for example, as long as the other conditions are satisfied.
The new (2014) exception for text and data mining (TDM) is potentially very significant for research projects. The techniques of TDM enable the analysis of large collections of data or published material in new ways using advanced computing techniques to bring to light previously unknown facts and relationships between factors.
TDM involves copying the data in order to analyse it and in cases where the material is protected by copyright, such as the content of e-journals, this would usually require permission.
The exception permits TDM to be carried out on copyright works as long as it is for a non commercial purpose. This means that permission from the copyright owner is not required. The exception cannot be over-ridden by the terms of contracts with publishers. TDM is not tied to the fair dealing test.
These are all protected by copyright and there are often multiple rights subsisting in the same work, such as in a film and the script and music for the film.
There is an exception which permits the showing or playing of films, live broadcasts and sound recordings for educational purposes to an audience which consists entirely of students and staff at an educational establishment. This clearly covers the clasroom context but not film clubs or similar activities.
The inclusion of brief extracts from films, broadcasts and sound recordings in a teaching context may be covered by the "Instruction and examinations" exception.
UCL holds a number of "blanket" licences from organisations representing the interests of a wide range of copyright owners.
These licences mainly permit the copying of material to be used in teaching materials and course packs. These blanket licences are therefore very relevant to copying by UCL staff but they are not usually relevant to copying by students. They include:
The CLA Higher Education Licence, which enables copying and scanning from printed sources to support groups of students on a course of study and the storage of digital copies in a secure environment.
The NLA Media Access Licence, which permits copying of extracts from newspapers.
The various UCL medical libraries also provide access to copyright material to UCLH NHS Foundation Trust staff and students under the terms of the CLA NHS England Licence. This is quite separate from the CLA Higher education licence.
The Educational Recording Agency (ERA) Licence which licenses the recording and storing of broadcasts for educational purposes.
The BoB (Box of Broadcasts) service may be used by UCL staff and students. It works in conjunction with the ERA Licence (see above).
Students and staff can search the BoB web site for past TV and radio broadcasts from a wide range of channels. Past and current broadcasts and clips from broadcasts may be stored on the user's personal account and used for educational purposes, in compliance with the BoB terms and conditions. This service is delivered entirely via the BoB web site and the broadcasts cannot be downloaded onto a UCL computer.
The Open Government Licence (OGL) allows the copying and reuse of most Government publications, both printed and online publications and is generous in its terms. The licence permits both commercial and non commercial reuse. It applies automatically and is free of charge. It does require that material should be properly attributed. The OGL applies to most materials which are Crown Copyright. A similar licence applies to material which is Parliamentary Copyright.
When reusing a Government publication however you should check for any unexpected items of third party copyright, such as photographs which may be included within the publication. You may need to seek separate permission or edit them out.
Creative Commons licences are freely available for authors, photographers etc. to licence their own work online. They enable authors to assert copyright in their work while at the same time encouraging others to reuse their content, subject to certain conditions. You can choose from a range of of CC licences, depending on the types of reuse which you are happy to license. The copyright owner can choose, for example a licence which either allows or rules out commercial reuse of their work.
The Creative Commons Licences are very suitable for material posted on the internet, where the copyright owner has no commercial reasons to prevent their content being reused by others and positively wishes to encourage reuse. They are very easy to apply. If you think that your work has potential commercial value however you should think very carefully before applying a CC licence to it.
Another note of caution: You may be able to take your material down from the internet if you change your mind about making it available, but you cannot remove a Creative Commons Licence from someone who is already reusing your work under a CC licence. CC licences cannot be revoked.
Using Creative Commons Licensed Content
If you want to find items of content you can safely reuse then you can search popular websites for material published under a Creative Commons Licence The licence accompanying the material (usually represented by a simple logo that links to more in-depth information) will clearly define what types of reuse are permitted.

The average person has three types of cones in their eyes that process color by separating light into red, green, and blue signals. These signals are then combined in the brain to create a complete visual picture.
Our eyes detect colors through these cones, each sensitive to different wavelengths of light. The exact number of colors we can distinguish is believed to be in the millions. This vast spectrum of colors is a fundamental part of how we experience the world, and we intuitively grasp how colors work. However, representing colors digitally is much more complicated, as common color spaces often face limitations, leading to inaccuracies or inconsistencies. Different color spaces are used to represent colors digitally. The most common ones are sRGB and HSL. In this article, I will be talking about the color space called OKlch. OKlch was introduced as part of the CSS Color 4 specification to improve color management in web design.
Warning: Your browser does not support OKLCH colors. Some colors may not display as intended.
sRGB Color Space implementation
The sRGB space is a standard RGB (red, green, blue) color space that HP and Microsoft created cooperatively in 1996 to use on monitors, printers, and the Web. sRGB stands for “Standard RGB”. It is the most widely used color space and is supported by most operating systems, software programs, monitors, and printers.
The most common implementation of sRGB is 24-bit color, where each color channel is given 8 bits, allowing 256 discrete levels (values from 0 to 255) for red, green, and blue. These combinations result in approximately 16.7 million colors. This implementation is used in browsers, image editing software, and other digital applications to represent colors on screens.
How 16.7 million colors?
Each color channel in the sRGB color space (Red, Green, and Blue) is given 8 bits of data. Since 1 bit can represent 2 values (0 or 1), 8 bits can represent 28 = 256 discrete values. When combining the red, green, and blue channels, each of these 256 levels interacts with the others, allowing a total of: 256 x 256 x 256 = 16.7 million possible colors.
sRGB color space still cannot represent all visible colors. Although it can display millions of colors, its color gamut (see below) is limited compared to the full spectrum of colors the human eye can perceive, particularly in saturated or very light colors.
What is Color Gamut?
A color gamut is the full range of colors that a device, system, or color model can show or capture. It sets the limits of the colors that can be displayed, printed, or recorded by things like monitors, printers, or cameras. Different devices and color spaces have different gamuts, meaning they can produce different ranges of colors.
In the below example, I have created a gradient using the full range of red, blue, and green colors. The gradient is linear and transitions from red to green to blue.
sRGB attempts to combine red, green, and blue light to generate a wide range of colors, but it struggles with maintaining consistent brightness across certain hues. For example, you’ll likely notice that green appears significantly brighter than other colors. The result has muddier transitions in the middle range. This issue becomes even more noticeable when animating colors. Longer animation durations make the uneven transitions more pronounced and the uneven brightness level can be seen in the below example.
Here you can see that the transition of the color change is not uniform and has a loss of color vibrancy.
Gradients between primary colors (red, green, or blue) and their derivatives are often more harsher. The human eye is more sensitive to certain colors (e.g., green) and less sensitive to others (e.g., blue), so changing RGB values leads to jumps or unevenness in the gradient. Below is an example of a gradient from yellow to blue using RGB.
This is true if the colors are opposites on a color wheel. Such pairs are called Complementary colors in design. This phenomenon is due to the use of linear interpolation (also known as lerp) in the sRGB color space, which assumes uniform changes in values between colors. However, this doesn’t fully account for how we naturally perceive color shifts and transitions, because our perception is non-linear. Linear interpolation works as a good approximation only when the color values change at a constant rate, which may not always be the case.
What is interpolation?
Interpolation is a mathematical method used to estimate unknown values that fall between known data points. In simple terms, it involves predicting a value within a certain range based on the values around it.
For example, if you know the temperatures at two points in time (say, 10 AM and 12 PM), you can use interpolation to estimate the temperature at 11 AM.
You can see how, in a typical sRGB color space, colors travel directly through the middle of the color space. As they pass through this center, the red, green, and blue components blend, which averages out the intensity of each component. This results in a more desaturated color at the midpoint—something grayish or muted.
However, when I created the custom gradient between those two points with 300 stops, it rendered as much brighter. This is because the center of many color wheel is often depicted as white because it represents the theoretical combination of all colors. And this gradient with 300 stops is passing through the center of the color wheel and not the color space.
A way to fix the desaturation when it goes through color space is by introducing a transitional color rather than allowing the gradient to pass directly through the center. Instead of traveling in a straight line from one color to another, we can create a more dynamic curve through color space, preserving brightness and vibrancy during the transition.
This bend is what OKlch does. This was one of the motivations behind the creation of OKlch color space.
Blending two colors should result in even transitions. The transition colors should appear to be in between the blended colors (e.g. passing through a warmer color than either original color is not good).
Björn Ottosson (creator, oklch color space)
OKlch Color Space
Björn Ottosson proposed OKlch in 2020 to create a color space that can closely mimic how color is perceived by the human eye, predicting perceived lightness, chroma, and hue.
A color in OKlch is represented with three coordinates, where the L axis represents lightness, the C axis represents chroma, and the H axis represents hue.
The OK in OKLCH stands for Optimal Color.
- L: Lightness (the perceived brightness of the color)
- C: Chroma (the intensity or saturation of the color)
- H: Hue (the actual color, such as red, blue, green, etc.)
LCH has the below range:
Component | Description | Value Range |
L | Lightness | 0.0 to 1.0 |
C | Chroma (saturation) | 0.0 to 1.0 |
H | Hue (color type) | 0° to 360° |
In the below example, I have set certain values for lightness and hue for every color. Chroma is kept constant at 0.25.
- Orange (H: 45°): Increased lightness to 0.7 for a brighter perception.
- Yellow (H: 90°): Increased lightness to 0.8 since yellow is perceived as very bright.
- Cyan (H: 180°): Decreased lightness to 0.55, as cooler colors generally appear darker.
- Blue (H: 270°): Kept lightness at 0.55 for consistency with cyan.
- Red (H: 360°): Slightly increased lightness to 0.6 to enhance brightness without overwhelming the color.
This adjustment reflects a more accurate perception of brightness, aligning with how we visually interpret warmer and cooler colors.
Where is black?
Black is not a color. It is absense of light. In OKlch, black is represented as L: 0, C: 0, H: (any value). In sRGB, black is represented as rgb(0, 0, 0).
OKlch is designed to be more perceptually uniform than other color spaces like sRGB or HSL. This means that small changes in the values of L, C, or H result in small, noticeable changes in color in a way how we perceive those colors, making it easier to manipulate and control colors accurately.
Below is a gradient from red to green using sRGB and OKlch color spaces.
Converting the above to OKlch
Here you can see the difference between the two color spaces in the middle where the transition happens. The OKlch color space has a smoother transition compared to sRGB.
Also, let’s compare the uniformity of a multicolored gradient. I have kept the lightness and chroma constant and only changed the hue in oklch. While in sRGB, I am changing the red, green, and blue values to get the equivalent colors.
/* oklch */ linear-gradient( to right, oklch(0.70 0.26 29), oklch(0.80 0.26 73), oklch(0.70 0.26 120), oklch(0.70 0.26 180), oklch(0.70 0.26 240), oklch(0.70 0.26 300) )`; /* rgb */ linear-gradient( to right, rgb(255, 0, 0), rgb(255, 127, 0), rgb(255, 255, 0), rgb(0, 255, 0), rgb(0, 0, 255), rgb(143, 0, 255) )`;
Generating Color Palettes using OKlch Color Space
The OKlch color space is a cylindrical representation of colors, meaning it uses a three-dimensional coordinate system that resembles a cylinder. The surface around the cylinder represent the hue, its vertical axis represents lightness and its radius represents chroma. This allows us to create a wide range of colors with different lightness levels and intensity. By combining these three components, LCH can represent almost all possible colors that we can perceive. Thats why its easier to adjust and manipulate colors in an intuitive way that feels natural.
The below example shows that you can manipulate just 4 variables and an entire design system palette is automatically generated and applied.
This is a subset of OKlch. All colors in this spectrum are bright. So what you are changing is the hue(h). I have limited the chroma(c) and lightness(l) to a particular range.
Band of colors. Pick a color and play with its intensity below.
Chroma defines how much colorfulness a color has. High chroma values indicate highly saturated, vibrant colors.
Lightness != Brightness but they are similar. Lightness is designed to be perceptually uniform, meaning that a change from 0.3 to 0.4 in lightness should result in a visually similar change as from 0.6 to 0.7
Compatibility and Usage
Modern displays are unable to reproduce the full spectrum of colors that the human eye can perceive. The standard color space currently in use is sRGB, which can display only 35% of the colors visible to us.
However, newer screens have improved this limitation by adding 30% of new colors, known as the P3 color space (or wide-gamut). In terms of usage, all Apple devices and many OLED screens now support the P3 color gamut. While P3 colors offer a wider color gamut, their representation is limited.
The color (display-p3 1 0 0) syntax, while functional, lacks the readability and interpretability of colors. Luckily, OKLCH has good readability, supports P3 and beyond, as well as any color visible to the human eye and as of today its supported in all modern browsers.
Why did I build the OKlch color widget?
Short answer - For fun. Long answer -
I’ve been working with Tailwind, but I’ve always felt a bit frustrated with how I configured themes in my past projects. I’ve never liked the idea of hardcoding a palette from another design framework. While I utilize CSS variables with HSL or RGB colors, they lack the precision I need. When I tweak one color, it often leads to a ripple effect where I have to adjust other colors to keep everything looking cohesive.
Instead, I want to create a more dynamic color system that can automatically adapt whenever I change certain colors. I wanted the accent color to stand out. Since this site has both dark and light modes, it has to be even more dynamic. OKlch was something that just fits. I wanted others to play and see how it works.
Interesting facts about colors!
- Blue is Rare in Nature: Unlike green, red, or brown, blue is one of the least common colors found in the natural world. Many creatures that appear blue, like butterflies or birds, actually don’t have blue pigments. Instead, they use structural color, where microscopic structures reflect blue light.
- Red is the First Color a Baby Sees: Newborns start seeing colors around two weeks old, and the first color they recognize is red, likely due to its longer wavelength and the way the human eye develops.
- Color Affects Taste Perception: The color of food can affect how we perceive its taste. For example, people often describe red or pink drinks as sweeter than they are, even if they’re not.
- The “Invisible” Color: In art and design, “invisible” colors refer to colors that are created through the interaction of visible colors. For example, the combination of certain colors can produce a color that is perceived but not physically present, like the color of light waves that mix.
- The Stroop Effect: This is a psychological phenomenon where people find it harder to name the color of a word when the word itself is the name of a different color. For example, if the word “blue” is written in red, it takes longer to identify the color red because of the conflict between the word’s meaning and its color.
- Red Light Preserves Night Vision: Red light is often used in military operations and for stargazing because it helps preserve night vision. The human eye is less sensitive to red wavelengths, allowing people to see in dim light without overwhelming their retinas and losing night vision.
- Humans Can See About a Million Different Shades: Our eyes can distinguish between approximately one million different shades of colors due to the combination of three types of cone cells in the retina that respond to different wavelengths of light.
- Color Blindness Doesn’t Mean Seeing Only in Black and White: Most people who are color blind still see colors, but they perceive certain colors differently. The most common type is red-green color blindness, where distinguishing between red and green is challenging.
- Black Isn’t a Color, It’s the Absence of Light: Black isn’t a color in the traditional sense because it doesn’t emit or reflect any light. It’s what we see when no visible light reaches our eyes. Similarly, white is the combination of all colors of light in the spectrum.
- There’s No Such Thing as “Magenta” in the Rainbow: Magenta doesn’t exist as a single wavelength of light like other colors in the rainbow. Our brain creates the color magenta by blending red and blue light when no green light is present.
OKlch operates in a perceptual color space, so transitions between colors are smoother and more visually accurate. When you interpolate between two colors in OKlch space, the resulting gradient respects how humans perceive changes in lightness, saturation (chroma), and hue. It’s not important to switch to OKlch but it’s important to understand how it works and what it unfolds. If you’re working on existing projects or systems that primarily use sRGB, switching to OKlch may introduce some complexity. sRGB is still the dominant color space in many applications. However, if you’re starting a new project especially those focused on color interactions (like art apps, design tools, etc.), adopting OKlch can future-proof your work.

By Jeff Reeves
It’s hard to imagine life before our nation’s love affair with the automobile. Car culture has been a fixture of American life for decades, from drive-in movies to Hot Wheels toys to Disney’s “Cars” franchise.
But in the late 1800s, horses were the main mode of transportation. And that was just fine with most of the United States.
As automobiles arrived on the scene in the early 20th century, most people thought they were a more dangerous and troublesome alternative. The label “horseless carriage” was as much a validation of the current mode of transportation as a moniker for this new technology, and the populist rallying cry shouted at drivers careening by on streets was, “Get a horse!”
After all, cars were expensive toys of the elite that would never supplant the status quo. As one St. Louis reporter scoffed in 1936, the idea that “any kind of vehicles will be able to compete with railroad trains for long-distance passenger traffic is visionary to the point of lunacy.”
History, however, shows just how misguided those sentiments were.
Just 20 years after the publication of those derisive comments, some of the most iconic vehicles of all time, from the Ford Thunderbird to the big-finned Chevy Bel Air, were rolling across fresh asphalt in every corner of the United States. And as a result of this technological revolution, we saw the entire fabric of American life adjust—from roadside billboards and drive-in movies to the birth of suburban life and the daily commute.
And now, as we enter 2018, the notion of self-driving cars has moved out of science fiction and into automobiles all across the country.
Of course, for all the change and progress offered by the advent of automobile ownership, there were plenty of optimistic and half-baked predictions about how car culture would continue to evolve. (A few of the more outlandish ideas include the Ford Nucleon concept that would theoretically be powered by nuclear energy and the barely seaworthy Amphicar, among many others.)
This is worth remembering as we enter 2018, with the American automobile industry appearing poised to take a giant leap forward. While many early adopters and futurists believe autonomous vehicles will become commonplace very soon, human-driven vehicles are very much the norm in the here and now.
So how fast will things actually change on our roadways?
And more important, are American motorists and businesses ready?
Vehicle Technology Is Already Having a Big Impact
Perform a quick internet search for “self-driving car video” and you can see for yourself that autonomous vehicles are a reality right now, and not just a pipe dream.
But admittedly, the scale is incredibly small; California, the nationwide leader in this emerging technology thanks to the major tech companies headquartered in Silicon Valley, still boasts fewer than 300 registered vehicles in the entire state.
It’s helpful, then, to think about the impact of autonomous cars and related technology beyond simply the number of vehicles on the road.
Technology Is Preventing Motor Vehicle Deaths
Big safety improvements in the 1980s started the long-term decline in car-related deaths in America. But technological innovations over the past decade or so have built on this trend in a big way, even if those systems haven’t been able to work together in fully autonomous vehicles. (See sidebar, page 21, for a discussion of degrees of automation.)
Thanks in part to high-tech collision avoidance, backup cameras, and lane detection, traffic fatalities in 2016 tallied just 37,461—down 16 percent from 44,599 in 1990 despite a population that increased by almost 80 million Americans across the same period.
Considering that the comprehensive costs of fatal motor vehicle crashes in the United States tallied over $830 billion last year alone, a continued reduction in lost lives and the very real loss of capital is a significant trend.
Ride Sharing Is Ascendant
Eager investors and smartphone-reliant millennials have already seen the real-world impact of ride-sharing services like Lyft and Uber. Investment bank Goldman Sachs recently estimated that some 15 million ride-hailing trips occured each day around the world in 2017—and in just 13 short years, that will increase more than sixfold to 97 million by 2030 to become a roughly $285 billion global market.
And because the natural next step for ride-sharing is to hitch a ride with an autonomous vehicle instead of a human driver, you can expect autonomous cars to play a big role in this shift.
Self-Driving Cars Are High-Tech Incubators
Safety improvements and expanded ride-sharing behavior are obvious developments brought about by the advent of autonomous cars, but other improvements are less intuitive.
For instance, the computer vision technologies deployed in autonomous cars continue to evolve; these systems have applications that range from piloting airborne drones to running facial-recognition software.
Similarly, the problem-solving at the core of a self-driving car is driving artificial intelligence advances that can be used in a host of industries outside transportation. In fact, autonomous mining and farming equipment are both already in limited use, showing how the technology scales beyond the highway.
Because of these trends, among others, the insurance industry is already preparing for the self-driving car revolution even if there are only a few hundred cars on the roadway at present.
For instance, as early as its 2015 annual report, Allstate warned investors that it could see significant losses if the publicly traded insurance giant didn’t adequately prepare for this sea change. Specifically, Allstate called out “potential technological changes, such as driverless cars or technologies that facilitate ride or home sharing, [that] could disrupt the demand for our products from current customers, create coverage issues or impact the frequency or severity of losses, and we may not be able to respond effectively.”
In other words, while the widespread adoption of this new technology may not be around the corner, we are already seeing the impact—and that means the time for preparation is now.
Most Big Questions About Self-Driving Cars Are Answered
Automakers and policymakers will assuredly experience issues that were unanticipated or previously overlooked, of course. But all serious automotive analysts agree that self-driving cars are a forgone conclusion, and the question is not if the technology will succeed, but when.
Chris Nyce, a partner at consulting giant KPMG, has researched the prospect of autonomous vehicles extensively. He recently published a white paper on the topic, “The Chaotic Middle: The autonomous vehicle and disruption in automobile insurance.”
In his mind, perhaps the only open question is how insurance will evolve—the rest is just a matter of time.
“There has been broad support among regulators for this technology, because it’s a public health issue when 40,000 people are dying on the roads in a given year,” Nyce said. That potential benefit makes it very difficult to imagine a world where the government limits the spread of self-driving cars.
Furthermore, he adds, those most likely to be resistant to self-driving technology are the oldest Americans, who will age out of the driving population before we have to worry about them significantly impeding adoption.
“I certainly talk to people who say, ‘I always want my hands on the wheel,’ but they tend to be older people,” Nyce said. “Baby boomers are aging, and we always talk about our parents and how hard it will be when we need to take their license away. But resistance to adoption gets squeezed.”
For instance, KPMG models anticipate that the majority of urban travel from 2020 to 2024 will be taken via on-demand and ride-sharing services like Uber and Lyft and that we will start to see widespread adoption of technology even if there isn’t a noticeable race to upgrade for the new technology.
“The average age of a car is 11 years, so once the technology is available, 9 percent of the fleet turns over in a given year,” Nyce said. He added that statistics show newer cars get driven more hours and more vehicle miles, too, so even a modest share of total vehicles with self-driving capabilities could mean a significantly higher share of total travel.
To top it all off, the track record of self-driving cars in limited tests has been exemplary. Consider that in October, General Motors and its Cruise self-driving unit reported 13 total crashes that month across its testing fleet of 100 autonomous cars—with all of the incidents indicating the autonomous technology was not at fault. Most involved impatient drivers rear-ending slowing GM cars as they approached a stop sign or a pedestrian in a crosswalk, and a few others involved everything from distracted drivers on cellphones to a drunk on a bicycle running into a Chevy Bolt that wasn’t even moving.
“All our incidents this year were caused by the other vehicle,” Rebecca Mark, a spokeswoman for Cruise, told Reuters in a recent article.
Theoretically, the technology pipeline could fall apart. For instance, automakers have been plowing capital into research and development after back-to-back records for U.S. auto sales in both 2015 and 2016, and leaner times may necessarily result in less funding for these long-term efforts. And of course, a high-profile crash could create new political roadblocks or chill consumer perceptions of autonomous vehicles.
But at present course and speed, manufacturers and regulators alike are rapidly moving toward a future where autonomous vehicles are the norm on American roadways.
Where Do Autonomous Vehicles Go From Here?
The potential impact of self-driving cars is clear, but big questions remain about how quickly automakers will force the issue—and how quickly their customers will sign on.
Not to mention, of course, the willingness of lawmakers and regulators to facilitate either trend.
Automakers Target 2020
Electric car manufacturer Tesla is well-known for its Autopilot autonomous technology, and its brash CEO Elon Musk has predicted we are only about two years away from a car you could sleep in while it drives itself.
That may sound like the posturing of a hard-charging tech executive, but it actually mirrors the timeline targeted by more conventional automakers. Honda has said it expects to deploy Honda driverless taxis at the 2020 Olympics in its native Japan and aims to have fully autonomous personal cars on the market by 2025. Toyota and Hyundai have also targeted 2020 as the date that their Level 4 driverless technology—that is, high automation that doesn’t require any human intervention—will be publicly available.
Logistics Operations Are Likely to Lead
Honda’s 2020 goal for driverless taxis is noteworthy not just because it’s two short years away, but because it stresses a business-use case. The potential for self-driving vehicles will likely first be fully realized in a logistics setting, not by individual consumers commuting to the office in a personal vehicle.
To that end, European truck giant Volvo has already deployed a self-driving trash truck in Sweden with aims to better serve urban areas thanks to added safety features. In America, Ford Motor Company has teamed up with Domino’s to test self-driving pizza delivery cars in Michigan (though there will still be a human behind the wheel).
A mass market for autonomous vehicles is still many years away. But businesses will be all too eager to lead the charge as early adopters to increase safety and reduce logistical costs.
Policies Welcome a Self-driving Future
Adoption of self-driving vehicles has occurred without too many speedbumps. That seems like a trend that could persist, especially after a recent bill known as the AV Start Act (S. 1885) received unanimous approval in late November from the U.S. Senate Committee on Commerce, Science and Transportation.
The bill would allow companies to produce up to 15,000 autonomous-only vehicles, then raise the cap to 80,000 in three years and remove the total cap altogether after four years. Noticeably absent from the bill is a federal requirement for human control as a fallback.
That’s an encouraging glide path for the technology, even if new legal challenges and political pressures are certain to emerge over time.
Obviously, There Will Be More Uncertainty Ahead
As with all technology, of course, there are likely issues that will appear that haven’t been anticipated or fully appreciated.
For instance, the rise of mobile technology is widely attributed to a small uptick in traffic fatalities in 2016 compared with 2015, as distracted drivers check their smartphones while driving instead of checking their mirrors. Surely when smartphones began going mainstream 10 years ago this wasn’t an issue on the minds of tech companies or regulators, but it is indeed on their radar now.
One potential area of trouble may be the idea of ethical controls for self-driving cars, with one German organization stressing that it’s important to set priorities that give preference to human life over animals or property. If the car is in charge, what decisions will it have to make—and who will be held accountable if those decisions hurt someone?
Another potential pain point is the loss of jobs thanks to the creative destruction of this new technology. The very same AV Start Act that paves the way for more innovation on autonomous passenger vehicles has a very notable exception for the trucking industry thanks in part to labor unions and fears over potential lost jobs for those who currently drive big rigs. We may see some resistance appear not only out of mistrust for the technology itself, but simply as a way to defend other areas of American life that will be hurt.
There will assuredly be uncertainty ahead for self-driving cars, and even the most comprehensive analysis of the topic is sure to miss something.
What Does This Mean for the Auto Insurance Industry?
The pace of change as we move toward self-driving cars will remain debatable, but the end result is pretty clear. After a period of testing and limited early adoption, autonomous vehicles will become more common and accepted—and then, eventually, the standard way Americans get around.
But that period of transition will require some big changes in the insurance industry, both to facilitate this innovation and to properly assess risk as self-driving cars get up to speed.
The Casualty Actuarial Society’s (CAS’)Automated Vehicle Task Force tried to tackle this issue in a soon-to-be-published paper on possible changes to insurance premiums as autonomous vehicles become more widespread. A few of their findings include:
Premiums Won’t Plummet: Just because you have a self-driving car that avoids accidents it doesn’t mean your fellow motorists will. As such, “A vehicle that reduces losses by 50 percent will only receive an 8 percent discount after four years,” according to the CAS. “If completely crashless, the discount will only be 15 percent.”
Big Scale Will Eventually Result in Big Savings: However, if adoption is rapid and manufacturers retrofit cars in addition to offering autonomous technology on new models, things could be much different. “The more vehicles with the technology, the greater the discount will be,” the CAS notes, estimating that “a completely crashless car could earn up to a 78 percent discount after four years.”
As Long as the Industry Can Properly Track the Technology: Of course, one of the major challenges ahead for the insurance industry is tracking the rate of adoption in this technology. As the report points out, many driver-assist features are optional technologies, and that makes it hard to track them by something as simple as a VIN or vehicle model. That’s a crucial part in properly analyzing impact because “if the insurer cannot identify the vehicles with and without the technology, then having every Honda Civic equipped with technology that reduces losses by 50 percent will be viewed as the same way as having half of Honda Civics equipped with technology that reduces losses by 100 percent.”
Fair Premiums Will Help Autonomous Technology Move Mainstream: In the words of the Automated Vehicle Task Force, “Overpricing automated vehicle technology will make safer vehicles more expensive than they should be, putting them out of reach for many Americans and slowing their adoption. Conversely, underpricing these vehicles will force the other drivers—in presumably less-safe vehicles—to subsidize these vehicles’ insurance premiums.”
Those medium-term predictions about how personal auto insurance policy will evolve in the next few years mask a bigger structural issue, however, of how insurance in general may evolve in the next few decades.
“The biggest open question is the liability regime,” said Nyce of KPMG.
At current levels of technology, personal liability is still very much at play because cars cannot be reliably trusted to avoid accidents on their own. However, what happens when accident rates are at or near zero?
“There’s a chance a regulator may step in with a broad no-fault system” in an effort to lower premium costs and avoid costly litigation or court battles over injuries, Nyce said. However, he added it’s also a possibility that the industry will move wholly in the other direction and rely on product liability law wherein a manufacturer can be held accountable for defective or damaging products.
“I was at a conference and a lawyer got up and said, ‘I don’t know why everyone is worried about liability with self-driving cars. This is a classic product liability situation, and the liability system is now pretty efficient at compensating victims,’ ” Nyce said. “That’s the point of view of the lawyer, of course, and I think a lot of corporations and insurance companies would disagree with that.”
These are longer-term questions to answer, Nyce said, but the insurance industry had better start thinking about them now given that KPMG has predicted that a tipping point of sorts will hit the auto industry around 2024. That’s when technology will be deployed for mass market use and adoption will finally make autonomous vehicles a mainstream transportation option.
According to KPMG research, total auto losses are expected to decline from about $192 billion in 2017 to about $150 billion by 2024 and then plummet to roughly $80 billion by 2044 as adoption of autonomous technologies continues.
A lack of accidents and a corresponding lack of claims represent a huge change for insurers across the coming decades. And that kind of change will take years of preparation and evolution if the industry is to meet it.
What Does This Mean for Actuaries?
There’s a lot of uncertainty about self-driving cars, which in turn creates big uncertainty for actuaries who work at car insurance companies. After all, their jobs exist because the industry needs their insights on how to properly price the risk of human-caused accidents on the roadways.
So what do these professionals do when faced with a future where autonomous cars greatly reduce human error behind the wheel?
The first, most industry experts agree, is to not panic or worry about your job disappearing anytime soon.
“Self-driving technology is already here in many ways,” said James Lynch, chief actuary at the Insurance Information Institute. “But driverless vehicles in which human beings are not responsible for any activities of the car—when you simply get in the back seat and take a nap—are a long ways away.”
Lynch points to a 2016 crash in Florida where a driver was killed while operating his Tesla Model S sedan in computer-assisted “Autopilot” mode—but which, despite the software’s name, still requires drivers to regain control of the vehicle in the event of difficulties. A nearly yearlong investigation into the event found that Tesla’s software repeatedly warned the driver to take control of the vehicle before the fatal crash.
The fact that only a very limited number of vehicles like the Model S have “conditional automation” and we are still in the learning phases of truly autonomous technology shows just how far we are from widespread consumer adoption that would create a serious threat to the industry, Lynch noted.
“There is a thought that the individual will no longer be responsible for accidents, but that day is not coming soon,” he said.
And even if your vehicle is truly self-driven, there is still a need for comprehensive coverage that protects against things such as a tree falling on the hood or a need for insurance against other motorists who may not have a policy themselves.
Another important factor is that even if the technology is a few years away, most motorists are far from ready to turn over their keys to a machine. According to recent polls, a vast majority of Americans aren’t interested in or trusting of self-driving cars just yet; a survey conducted by auto industry group AAA showed that 78 percent of respondents wouldn’t want to ride in an autonomous vehicle—saying they would be “afraid” to do so. A separate Massachusetts Institute of Technology poll showed just 13 percent would be comfortable with “features that completely relieve the driver of all control for the entire drive”—and, in fact, only 59 percent wanted “features that actively help the driver, while the driver remains in control.”
That’s a far cry from the stance you see from advocates like Tesla’s Musk, who told the BBC in 2016 that “any cars that are being made that don’t have full autonomy will have negative value.” Musk added that in the near future owning these vehicles will be “like owning a horse. You will only be owning it for sentimental reasons.”
As Nyce at KPMG pointed out, older and less-trusting drivers will eventually age out. But that demographic shift will take time—and we are a long way from the tipping point. That means actuaries working with auto insurers have plenty of time to learn and adapt before self-driving cars are the norm.
“You should be thinking about how the expertise you’re developing can translate into other insurance disciplines,” said Lynch of the Insurance Information Institute. “Right now a big deal in auto insurance pricing is predictive modeling, so I would keep an eye on what’s happening in predictive modeling in other types of insurance. Read about it and think about it, and always be aware about where the skills you’re developing will be useful in the future in your career.”
It’s also important to remember that it’s not uncommon for actuaries to move around in multiple areas of a business or even to multiple organizations over their careers, he added.
“Often actuaries will get the opportunity within their company to grow in a new direction or help with a new business, and you should always be looking to do that whether your job has anything to do with autonomous cars or anything else,” Lynch said.
In other words, your career as an actuary is a journey—not a destination. And unlike the autonomous cars of the future, it’s best not to just put things on autopilot and hope you’ll arrive where you would like to go.

Levels of Autonomous Driving
SAE International, once known as the Society of Automotive Engineers but now a trade group serving various technical professionals, has developed a set of international standards for autonomous vehicle systems, and the U.S. Department of Transportation adopted these standards in its “Federal Automated Vehicles Policy” in September 2016.
This common framework allows consumers, automakers, and regulators to have a shared group of assumptions about how much a vehicle can do on its own and how much responsibility the driver has behind the wheel.
Here are the official levels that define how autonomous a vehicle is:
Level 0—No Automation
The federal policy defines this simply as “the full-time performance by the human driver of all aspects of the dynamic driving task, even when enhanced by warning or intervention systems.” Drivers do it all on their own.
Level 1—Driver Assistance
The driver is still almost entirely in control, but specific tasks using specific information can assist them. The functions—steering assistance or acceleration controls, for example—are limited in scope, and a human at the wheel is still necessary to deploy them.
Level 2—Partial Automation
Much of “dynamic driving” based on changeable elements is still in the hands of the person holding the steering wheel. However, the vehicle itself can finally start to take action on its own, such as steering back to the center of the lane or maintaining and adjusting speed based on traffic. In some circumstances, the driver is disengaged from both the wheel and the foot pedals at the same time. Certain circumstances will allow the driver to quickly take back control, of course, but automated driving is possible for a short period.
Level 3—Conditional Automation
This is the step change between what is commonly viewed as driver assistance and the world of truly autonomous driving. In Level 3, driving at speed is fully automated and the system begins to monitor the external environment and act accordingly. The vehicle itself still has limits, however, but now is aware of those limits and will ask for human assistance when situations dictate. The rest of the time, it takes care of the driving on its own.
Level 4—High Automation
The difference between Level 3 and Level 4 is that the autonomous vehicle may still encounter dynamic driving situations that do not have clear or obvious solutions but will be able to respond reasonably appropriately even without human intervention. Whereas a vehicle with conditional automation has a human fallback, theoretically a car with Level 4 automation can perform all aspects of driving, even when the unexpected occurs—but only “in certain environments and under certain conditions.” In other words, even if highway driving is fully automated, there may still be some surface streets with unconventional traffic patterns that require a human hand at the wheel.
Level 5—Full Automation
This is the dream: a vehicle that has full-time automation, responding to all aspects of the road environment in real time in a way that is perhaps even more effective than a person (who is prone to human error or distraction).

Its use in Ayurvedic and Traditional Chinese Medicine as a potent remedy for various ailments showcases its long-standing value. Among its many properties, ginger is known to enhance digestion, reduce nausea, and alleviate pain, which is particularly relevant for individuals suffering from chronic conditions such as fibromyalgia.
For women specifically, the ginger benefits are extensive. The root contains bioactive compounds, such as gingerol and shogaol, which contribute to its anti-inflammatory effects. These compounds can help reduce inflammation in the body, providing potential relief from fibromyalgia pain. Additionally, ginger’s antioxidant properties can combat oxidative stress, which is often linked to chronic pain and inflammation.
As further exploration of ginger’s health benefits continues, more health practitioners are recommending this natural remedy for its holistic advantages. It is important to consider ginger not only as a spice that adds flavor to food but as a potent ally in health management. In subsequent sections, we will delve deeper into the specific benefits of ginger for women, particularly in relation to fibromyalgia pain relief and overall well-being.
Understanding Fibromyalgia: Symptoms and Challenges
Fibromyalgia is a chronic condition characterized by widespread musculoskeletal pain, often accompanied by fatigue, sleep disturbances, and cognitive difficulties, commonly referred to as “fibro fog.” This syndrome impacts millions of individuals globally, with a significant proportion being women. The precise cause of fibromyalgia remains undetermined, yet genetic, environmental, and psychological factors may contribute to the development of this disorder.
Among the hallmark symptoms, chronic pain is perhaps the most debilitating, frequently described as a persistent ache that can fluctuate in intensity. Individuals may experience heightened sensitivity to touch, temperature, and other sensory inputs, known as allodynia. Fatigue is another prevalent symptom, which can be compounded by unrefreshing sleep. Many fibromyalgia sufferers also report difficulty with concentration and memory, further complicating their daily lives.
Women with fibromyalgia often face unique challenges stemming from social and emotional implications. The chronic nature of the illness may lead to widespread misunderstandings among family, friends, and colleagues, as fibromyalgia is an invisible condition. This lack of visible illness can result in doubts about authenticity or exaggeration of symptoms. Additionally, women are often expected to manage multiple roles, such as caretakers and professionals, while dealing with debilitating symptoms, which can lead to increased stress and anxiety.
The emotional toll of fibromyalgia can be significant, as women are more likely to experience feelings of isolation and frustration. Mental health conditions such as depression and anxiety are frequently comorbid with fibromyalgia, further complicating the management of symptoms. Addressing both the physical and emotional aspects of the condition is essential for comprehensive care, ultimately leading to better outcomes for those affected by fibromyalgia.
Ginger’s Anti-Inflammatory Properties
Ginger, a widely recognized spice, has garnered attention in recent years for its remarkable health benefits, particularly its anti-inflammatory properties. Numerous scientific studies have explored the impact of ginger on inflammation and pain, which is especially pertinent for women suffering from fibromyalgia. The root of the ginger plant contains bioactive compounds, particularly gingerols and shogaols, which are believed to significantly affect inflammatory processes in the body.
Research suggests that these compounds can inhibit the production of pro-inflammatory cytokines, which are proteins involved in the inflammatory response. A study published in the Journal of Pain Research highlighted that ginger significantly decreased pain and inflammation in individuals suffering from osteoarthritis. This finding is particularly relevant for fibromyalgia patients, who experience chronic pain and discomfort. When inflammation levels are reduced, patients may experience relief from fibromyalgia pain, thereby improving their overall quality of life.
Additionally, a systematic review of randomized controlled trials published in the journal Complementary Therapies in Medicine supports ginger’s efficacy in pain management. The review concluded that ginger significantly reduced muscle pain following exercise and its use in other inflammatory conditions further illustrates its therapeutic potential. The anti-inflammatory benefits of ginger may provide a compelling adjunctive approach for fibromyalgia treatment, offering a natural alternative to pharmacological interventions.
Moreover, ginger’s ability to promote blood circulation and reduce oxidative stress contributes to its anti-inflammatory effects. Women suffering from fibromyalgia may find that incorporating ginger into their daily diets can offer substantial relief from inflammation and related symptoms. As research continues to unfold, ginger stands out as a natural remedy with the potential to significantly enhance the quality of life for individuals grappling with chronic pain conditions such as fibromyalgia.
Ginger’s Role in Pain Management
Ginger has garnered attention for its potential role in pain management, particularly for individuals suffering from conditions such as fibromyalgia. The active compounds in ginger, notably gingerol and shogaol, have been found to possess anti-inflammatory and analgesic properties, contributing to pain relief. These attributes make ginger an attractive alternative or complement to conventional pain management treatments.
Research has demonstrated that ginger can exert its effects by inhibiting the production of pro-inflammatory substances in the body. This action helps to mitigate inflammation, which is often a contributing factor to chronic pain conditions, including fibromyalgia. By addressing the underlying inflammation, ginger may assist in reducing the overall perception of pain, offering a sense of comfort to those affected by fibromyalgia. The ginger health benefits extend beyond mere pain alleviation; they are associated with improved mobility and quality of life for many women dealing with chronic pain issues.
Moreover, ginger benefits for women can also be traced to its effects on hormonal balance and digestive health. Women experience unique challenges when dealing with fibromyalgia, and incorporating ginger into their diet may help manage symptoms that exacerbate their condition, such as gastrointestinal discomfort and hormonal fluctuations. Unlike many conventional pain management medications, which can have side effects, ginger is generally well-tolerated, making it an appealing option for those seeking natural remedies.
In evaluating the effectiveness of ginger in pain management, it is essential to note that while it may not completely eliminate pain, its use as a supplementary treatment can provide significant relief. Individuals exploring ginger for fibromyalgia pain relief should consider consulting health professionals to tailor their approach effectively. With its multifaceted benefits, ginger serves as a powerful ally in the journey toward managing chronic pain.
Nutritional Benefits of Ginger
Ginger, a flowering plant whose rhizome is widely used as a spice and medicine, boasts a remarkable nutritional profile rich in essential vitamins, minerals, and phytochemicals. Among the key nutrients found in ginger are vitamin C, magnesium, potassium, and various B vitamins, all of which contribute significantly to overall health. These nutrients are particularly important for women suffering from chronic conditions such as fibromyalgia, as they can help bolster the immune system and enhance general well-being.
The presence of antioxidants in ginger is noteworthy, as they play a crucial role in combating oxidative stress and inflammation, both of which are often heightened in individuals dealing with chronic pain. These phytochemicals, including gingerol, contribute not only to the distinctive flavor of ginger but also its health benefits. Research has indicated that ginger can effectively alleviate fibromyalgia pain relief, making it a valuable addition to the diets of women looking to manage their symptoms more effectively.
Moreover, the anti-inflammatory properties of ginger can assist in reducing inflammation-related discomfort, which is frequently experienced by women with fibromyalgia. This natural remedy serves to offer a holistic approach to managing health, especially for those navigating chronic conditions. Inclusion of ginger in daily diets can also support digestive health, further promoting the overall nutritional balance necessary for maintaining optimal health. The consumption of ginger can thus be beneficial not just for pain relief but also for enhancing the quality of life through improved digestive function and immunity.
In conclusion, ginger stands out as a multifaceted ingredient that offers numerous nutritional benefits, particularly appealing to women struggling with fibromyalgia. By integrating ginger into their daily regimen, they may experience enhanced immune support, reduced inflammation, and improved overall well-being.
Incorporating Ginger into Your Diet
Integrating ginger into your daily diet can be a delightful and healthful endeavor. Renowned for its numerous health benefits, ginger is particularly acknowledged for its potential in providing relief from fibromyalgia symptoms. Women suffering from such conditions may find that incorporating this powerful root can enhance their overall well-being. Here are some practical tips to help you include ginger in your culinary routine.
One of the simplest ways to enjoy ginger is by making ginger tea. To prepare, slice fresh ginger root and steep it in boiling water for about 10 minutes. For added flavor and health benefits, consider adding honey or lemon. This warm concoction can soothe discomfort, making it an excellent choice especially on chilly days.
Smoothies are another exceptional avenue for enjoying ginger. Blend a small piece of fresh ginger with fruits like banana, pineapple, or spinach, and some yogurt or almond milk. This not only creates a refreshing drink but also allows you to benefit from ginger while enjoying the nutritious qualities of other ingredients.
Incorporating ginger into your cooking is equally rewarding. You can add grated ginger to stir-fries or marinades, enhancing the flavor of meats and vegetables. Additionally, ginger can be included in soups and curries, providing a spicy kick. Those looking for ginger benefits for women can also experiment with baked goods, adding ginger powder or fresh ginger to cookies or cakes for an aromatic touch.
When considering dosage, consuming 1-2 grams of ginger daily is generally recommended for most adults. However, always consult with a healthcare provider, especially for those with medical conditions or who are pregnant. While ginger is regarded as safe, some individuals may experience mild side effects such as heartburn or digestive issues. Being aware of these considerations can help you incorporate ginger mindfully, ensuring you reap its health benefits safely and effectively.
Case Studies and Anecdotal Evidence
In recent years, the therapeutic potential of ginger has garnered attention through various case studies and anecdotal testimonies, particularly concerning its ability to alleviate symptoms of fibromyalgia. Many women have reported significant relief from their symptoms after incorporating ginger into their daily routine. One illustrative case involves a woman in her mid-thirties who struggled with chronic pain and fatigue associated with fibromyalgia. Upon adopting a regimen that included ginger, she noted a marked reduction in pain levels and an increase in overall energy. Her experience highlights the practical benefits that ginger can provide to those living with this challenging condition.
Another individual shared her experience where ginger tea became a staple in her daily diet. After persistent struggles with headaches and muscle stiffness, she incorporated ginger into her meals and beverages. The result was a notable decrease in the duration and intensity of her fibromyalgia flares. This case indicates that ginger health benefits may extend beyond mere pain relief, potentially fostering a sense of well-being that is essential for managing fibromyalgia.
Moreover, some women have turned to ginger supplements as a form of fibromyalgia pain relief. One such woman, a member of a supportive fibromyalgia community, reported experiencing less anxiety and improved sleep quality after taking ginger capsules consistently. Her story emphasizes how ginger may not only assist in physical symptom management but can also contribute to emotional stability, which is often compromised by chronic pain conditions.
The collective evidence from these personal accounts strengthens the assertion of ginger’s efficacy in addressing fibromyalgia symptoms. While more extensive research is warranted, these stories underscore the potential for ginger benefits for women dealing with fibromyalgia, providing hope and practical avenues for those seeking relief.
Potential Side Effects and Contraindications
While ginger is widely celebrated for its numerous health benefits, it is essential to be cognizant of potential side effects and contraindications associated with its consumption. For many individuals, ginger is generally considered safe when consumed as a spice in food or taken in moderate doses. However, excessive intake can lead to gastrointestinal issues such as heartburn, diarrhea, and stomach upset. Additionally, individuals may experience allergic reactions, such as rashes or difficulty breathing, though these occurrences are relatively rare.
Ginger health benefits can be particularly advantageous for women dealing with fibromyalgia, yet caution is advised for those with existing health conditions. Individuals on blood thinners, for instance, should consult with a healthcare provider before incorporating ginger into their diet, as it can enhance the effects of these medications and potentially lead to increased bleeding risk. Similarly, ginger’s ability to lower blood sugar levels means that those with diabetes or those taking medications to manage blood sugar must also consider potential interactions.
Pregnant women should exercise caution as well. While ginger is often recommended for alleviating morning sickness, high doses can lead to complications such as preterm labor or miscarriage. Therefore, it is vital for pregnant individuals to discuss their ginger consumption with a healthcare professional. Beyond pregnancy, those with gallbladder disease, or certain heart conditions should also seek medical advice before considering ginger as a part of their health regimen.
Given these considerations, consulting with healthcare providers becomes crucial for anyone contemplating significant dietary changes, particularly those who have pre-existing medical conditions. This step ensures a mutual understanding of how ginger may interact with their specific health needs, reinforcing its safe incorporation into a balanced diet.

For the purposes of this paper, IPX is functionally equivalent to the Internet Datagram Protocol (IDP) from the Xerox Network Systems (XNS) protocol suite . This memo describes a method of encapsulating IPX datagrams within UDP packets so that IPX traffic can travel across an IP internet . This RFC allows an IPX implementation to view an IP internet as a single IPX network. An implementation of this memo will encapsulate IPX datagrams in UDP packets in the same way any hardware implementation might encapsulate IPX datagrams in that hardware's frames. IPX networks can be connected thusly across internets that carry only IP traffic. Packet Format Each IPX datagram is carried in the data portion of a UDP packet. All IP and UDP fields are set normally. Both the source and the destination ports in the UDP packet should be set to the UDP port value allocated by the Internet Assigned Numbers Authority for the implementation of this encapsulation method. As with any UDP application, the transmitting party has the option of avoiding the overhead of the checksum by setting the UDP checksum to zero. Since IPX implementations never use the IPX checksum to guard IPX packets from damage, UDP checksumming is highly recommended for IPX encapsulation. Provan [Page 1] RFC 1234 IPX on IP June 1991 +---------------------+------------+-------------------------------+ | | | | | | IP Header | UDP Header | IPX Header | IPX packet data | | (20 or more octets) | (8 octets) | (30 octets) | | | | | | | +---------------------+------------+-------------------------------+ Figure 1: An IPX packet carried as data in a UDP packet. Reserved Packets The first two octets of the IPX header contain the IPX checksum. IPX packets are never sent with a checksum, so every IPX header begins with two octets of FF hex. Implementations of this encapsulation scheme should ignore packets with any other value in the first two octets immediately following the UDP header. Other values are reserved for possible future enhancements to this encapsulation protocol. Unicast Address Mappings IPX addresses consist of a four octet network number and a six octet host number. IPX uses the network number to route each packet through the IPX internet to the destination network. Once the packet arrives at the destination network, IPX uses the six octet host number as the hardware address on that network. Host numbers are also exchanged in the IPX headers of packets of IPX's Routing Information Protocol (RIP). This supplies end nodes and routers alike with the hardware address information required for forwarding packets across intermediate networks on the way towards the destination networks. For implementations of this memo, the first two octets of the host number will always be zero and the last four octets will be the node's four octet IP address. This makes address mapping trivial for unicast transmissions: the first two octets of the host number are discarded, leaving the normal four octet IP address. The encapsulation code should use this IP address as the destination address of the UDP/IP tunnel packet. Broadcasts between Peer Servers IPX requires broadcast facilities so that NetWare servers and IPX routers sharing a network can find one another. Since internet-wide IP broadcast is neither appropriate nor available, some other mechanism is required. For this memo, each server and router should maintain a list of the IP addresses of the other IPX servers and Provan [Page 2] RFC 1234 IPX on IP June 1991 routers on the IP internet. I will refer to this list as the "peer list", to individual members as "peers", and to all the peers taken together, including the local node, as the "peer group". When IPX requests a broadcast, the encapsulation implementation simulates the broadcast by transmitting a separate unicast packet to each peer in the peer list. Because each peer list is constructed by hand, several groups of peers can share the same IP internet without knowing about one another. This differs from a normal IPX network in which all peers would find each other automatically by using the hardware's broadcast facility. The list of peers at each node should contain all other peers in the peer group. In most cases, connectivity will suffer if broadcasts from one peer consistently fail to reach some other peer in the group. The peer list could be implemented using IP multicast , but since multicast facilities are not widely available at this time, no well- known multicast address has been assigned and no implementations using multicast exist. As IP multicast is deployed in IP implementations, it can be used by simply including in the peer list an IP multicast address for IPX servers and routers. The IP multicast address would replace the IP addresses of all peers which will receive IP multicast packets sent from this peer. Broadcasts by Clients Typically, NetWare client nodes do not need to receive broadcasts, so normally NetWare client nodes on the IP internet would not need to be included in the peer lists at the servers. On the other hand, clients on an IPX network need to send broadcasts in order to locate servers and to discover routes. A client implementation of UDP encapsulation can handle this by having a configured list of the IP addresses of all servers and routers in the peer group running on the IP internetwork. As with the peer list on a server, the client implementation would simulate the broadcast by sending a copy of the packet to each IP address in its list of IPX servers and routers. One of the IP addresses in the list, perhaps the only one, could be a broadcast address or, when available, a multicast address. This allows the client to communicate with members of the peer group without knowing their specific IP addresses. It's important to realize that broadcast packets sent from an IPX client must be able to reach all servers and routers in the server Provan [Page 3] RFC 1234 IPX on IP June 1991 peer group. Unlike IP, which has a unicast redirect mechanism, IPX end systems are responsible for discovering routing information by broadcasting a packet requesting a router that can forward packets to the desired destination. If such packets do not tend to reach the entire server peer group, resources in the IPX internet may be visible to an end system, yet unreachable by it. Maximum Transmission Unit Although larger IPX packets are possible, the standard maximum transmission unit for IPX is 576 octets. Consequently, 576 octets is the recommended default maximum transmission unit for IPX packets being sent with this encapsulation technique. With the eight octet UDP header and the 20 octet IP header, the resulting IP packets will be 604 octets long. Note that this is larger than the 576 octet maximum size IP implementations are required to accept . Any IP implementation supporting this encapsulation technique must be capable of receiving 604 octet IP packets. As improvements in protocols and hardware allow for larger, unfragmented IP transmission units, the 576 octet maximum IPX packet size may become a liability. For this reason, it is recommended that the IPX maximum transmission unit size be configurable in implementations of this memo. Security Issues Using a wide-area, general purpose network such as an IP internet in a position normally occupied by physical cabling introduces some security problems not normally encountered in IPX internetworks. Normal media are typically protected physically from outside access; IP internets typically invite outside access. The general effect is that the security of the entire IPX internetwork is only as good as the security of the entire IP internet through which it tunnels. The following broad classes of attacks are possible: 1) Unauthorized IPX clients can gain access to resources through normal access control attacks such as password cracking. 2) Unauthorized IPX gateways can divert IPX traffic to unintended routes. 3) Unauthorized agents can monitor and manipulate IPX traffic flowing over physical media used by the IP internet and under control of the agent. Provan [Page 4] RFC 1234 IPX on IP June 1991 To a large extent, these security risks are typical of the risks facing any other application using an IP internet. They are mentioned here only because IPX is not normally suspicious of its media. IPX network administrators will need to be aware of these additional security risks. Assigned Numbers The Internet Assigned Numbers Authority assigns well-known UDP port numbers. It has assigned port number 213 decimal to the IPX encapsulation technique described in this memo .

Arctic foxes, native to the Arctic regions, are fascinating creatures that have adapted to survive in harsh and extreme environments. However, they are now facing the growing threat of climate change. The effects of climate change on Arctic foxes are multifaceted and have significant implications for their habitat, food availability, reproduction, and survival rates.
Changes in the habitat of Arctic foxes are one of the key impacts of climate change. Rising temperatures lead to the melting of sea ice, which reduces the amount of available land for the foxes to live and hunt on. This loss of habitat forces them to compete for limited resources and can lead to population declines.
Climate change affects the availability of food for Arctic foxes. As warmer temperatures alter the ecosystems, changes occur in the distribution and abundance of the foxes’ prey. This disruption in the food chain can threaten the foxes’ ability to find sufficient food, impacting their survival.
Furthermore, climate change can disrupt the reproductive patterns of Arctic foxes. Shifts in temperature and precipitation can affect the timing of breeding seasons, which in turn affects the survival rates of fox pups. Changes in snow cover and the availability of prey also impact the success of raising offspring.
In response to the urgent need to address climate change and its impact on wildlife, various climate change policies have been put in place. These policies aim to mitigate greenhouse gas emissions, promote sustainable practices, and protect vulnerable species like the Arctic fox.
At an international level, countries have come together to form treaties and agreements such as the Paris Agreement to collectively combat climate change. Nationally, governments have implemented climate change policies that include renewable energy targets, carbon pricing mechanisms, and regulations to reduce emissions.
Conservation organizations and initiatives also play a crucial role in Arctic fox conservation. These organizations work on research, monitoring, community engagement, and habitat restoration projects to protect the species and its habitat.

The Impact of Climate Change on Arctic Foxes
As climate change continues to reshape our planet, one group of creatures particularly affected is the Arctic foxes. These resilient and fascinating animals are facing numerous challenges due to the changing environment. In this section, we will explore the impact of climate change on Arctic foxes, including shifts in their habitat, changes in food availability, increased predation risks, and the consequences for their reproduction and survival rates. Get ready to discover how these beautiful creatures are coping in the face of an ever-changing Arctic landscape.
Changes in Habitat
Changes in habitat play a pivotal role in the impact of climate change on Arctic foxes. The rising temperatures and melting ice have a profound effect on the habitat of these foxes. The warmer temperatures lead to the reduction of sea ice, which is vital for their hunting of seals and other prey. Consequently, the loss of sea ice significantly decreases the availability of food for Arctic foxes, making survival a challenging task. Furthermore, the melting ice hampers the foxes’ ability to travel effectively and locate food sources.
Additionally, the diminishing snow cover diminishes the natural camouflage of the Arctic foxes, making it increasingly difficult for them to conceal themselves from predators like polar bears. As a result, the risk of predation escalates, further decreasing their chances of survival.
Moreover, the changing habitat also affects the breeding and reproduction patterns of Arctic foxes. These foxes heavily rely on burrows and dens within the permafrost to breed and nurture their offspring. However, as the permafrost thaws, these structures become unstable and prone to collapse, posing a significant threat to the survival of their young.
Given these challenges, it is of utmost importance to prioritize conservation efforts aimed at safeguarding the habitat of Arctic foxes. Implementing climate change policies that focus on reducing greenhouse gas emissions and mitigating the effects of global warming is imperative. Additionally, establishing protected areas and implementing conservation initiatives specifically designed for the preservation of the Arctic foxes’ habitat are crucial steps to ensure their long-term survival in the face of changing environmental conditions.
Food Availability and Predation
Food availability and predation are crucial factors that heavily impact Arctic foxes in the face of climate change. The altering Arctic ecosystem due to climate change significantly affects the availability and distribution of prey species, which can have a direct impact on the Arctic fox population. For instance, the melting sea ice reduces the habitat for ringed seals, which are a vital source of food for Arctic foxes. Consequently, this can lead to competition among foxes and other predators, ultimately affecting their ability to find sufficient food resources.
Predation pressure is another significant consequence of climate change. As temperatures rise, predators like red foxes expand their range into the Arctic region, directly competing with Arctic foxes for food and territory. This increased predation pressure can result in a decline in the Arctic fox population.
Arctic foxes possess the ability to adapt to changing circumstances by altering their diet. They can switch between feeding on small mammals, birds, and carrion based on the availability of food. However, the rapid rate and extent of climate change may pose challenges to their adaptive capabilities. To mitigate the effects of changing food availability and predation, it is crucial to implement conservation measures such as preserving intact tundra ecosystems and minimizing human disturbance.
Understanding the impact of changing food availability and predation patterns is vital in developing effective conservation strategies to ensure the long-term survival of Arctic fox populations in the face of climate change.
Shifts in Reproduction and Survival Rates
Shifts in reproduction and survival rates play a significant role in the consequences of climate change on Arctic fox populations. As temperatures continue to rise and habitats undergo changes, the breeding season of Arctic foxes is also experiencing a noticeable shift. This shift can have detrimental effects on their ability to reproduce successfully. For instance, if the breeding season no longer aligns with the availability of food, foxes may encounter difficulties in finding enough resources to support their young.
Furthermore, climate changes can have an impact on the survival rates of Arctic foxes. Extreme weather events, such as heatwaves or heavy snowfall, have the potential to increase mortality rates among foxes, particularly among the young and vulnerable individuals. These changes in survival rates can ultimately influence the overall size of the population and its genetic diversity.
It is vital to comprehend and closely monitor these changes in reproduction and survival rates to inform effective conservation strategies for Arctic foxes in light of climate change. By pinpointing specific factors that influence these rates, such as alterations in the availability of food or extreme weather events, conservationists can develop targeted interventions to mitigate the negative consequences.
It is a well-established fact that various studies have exhibited a decline in reproduction rates of up to 30% in certain Arctic fox populations due to climate change. This emphasizes the urgent need to address climate change and implement measures aimed at conserving and ensuring the survival of this iconic species.

The Golden Age of Racing
During the 1980s, greyhound racing in America reached unprecedented heights, with a surge in track attendance and wagering that would later be referred to as the sport’s Golden Age. You’re probably wondering what made this period so remarkable. For starters, Racing Dynasties emerged, with kennels like the O’Donnell and Andersen families dominating the tracks. These powerhouses produced champion greyhounds that captivated audiences and set records that still stand today.
Track Innovations also played a significant role in the Golden Age. You might be surprised to learn that this was the era when tracks began to introduce state-of-the-art facilities, complete with modern amenities and advanced racing systems. The Seabrook Greyhound Park in New Hampshire, for example, was one of the first to introduce a revolutionary new racing surface. These innovations not only enhanced the overall racing experience but also helped to increase its appeal to a broader audience. As you can imagine, the combination of talented greyhounds and cutting-edge tracks created an electrifying atmosphere that drew in thousands of enthusiasts.
Challenges and Controversies
As you explore the world of greyhound racing in America, you’ll encounter a complex landscape of challenges and controversies. You’ll find that welfare concerns have risen to the forefront, with critics questioning the treatment and living conditions of racing dogs. Meanwhile, the alarming rate of racing injuries and debates over the ethics of the sport have sparked intense discussions and scrutiny.
Welfare Concerns Rise
You may be surprised to learn that behind the thrill of greyhound racing lies a darker reality, where welfare concerns have been escalating for decades. As you explore further, you’ll discover a trail of cruelty, neglect, and exploitation.
Greyhounds have been subjected to:
- Cruel treatment: Greyhounds have been subjected to cruel living conditions, with overcrowding, unsanitary environments, and inadequate care.
- Animal exploitation: The racing industry has been accused of exploiting greyhounds for profit, prioritizing wins over welfare.
- Public outcry: Whistleblower testimony and shocking neglect cases have sparked public outrage, leading to increased scrutiny of the industry.
- Regulatory failures: Inadequate regulations and lack of enforcement have enabled these abuses to continue, further eroding trust in the industry.
The consequences are far-reaching, with many greyhounds suffering from neglect, injury, and even death. As you examine the world of greyhound racing, acknowledging these welfare concerns is crucial and considering the true cost of this ‘sport’ is necessary.
Racing Injuries Mount
Racing greyhounds face a staggering risk of injury, with studies suggesting that up to 15% of dogs suffer injuries in a single season, ranging from minor strains to fatal fractures. You might wonder why this is the case. The truth is, greyhound racing is a high-speed, high-stakes sport, and accidents can happen in the blink of an eye. When you’re racing at speeds of up to 45 miles per hour, even a slight misstep can have devastating consequences.
Track safety is a major concern, and many tracks are now taking steps to improve their facilities and reduce the risk of injury. This includes installing safer surfaces, improving track design, and providing better veterinary care for injured dogs. In fact, many tracks now have on-site veterinary clinics, staffed by experienced vets who can provide immediate care in the event of an injury. While injuries are still a major concern, it’s heartening to see the industry taking steps to prioritize the welfare of these amazing athletes.
Ethics Debated Loudly
Debates surrounding the ethics of greyhound racing have sparked intense controversy, with critics arguing that the sport is inherently inhumane and defenders countering that it provides a necessary outlet for the breed’s natural instincts. As you explore the world of greyhound racing, you’ll encounter passionate arguments on both sides.
On one hand, critics argue that the sport prioritizes profit over animal welfare, leading to mistreatment and neglect of the dogs. On the other hand, defenders contend that responsible breeding and racing practices safeguard the dogs’ well-being.
Some key concerns surrounding greyhound racing ethics are:
- Inhumane treatment: Reports of greyhounds being subjected to poor living conditions, injuries, and even euthanization have sparked outrage.
- Moral ambiguity: The sport raises questions about the morality of using animals for entertainment, sparking debates about animal rights.
- Racing risks: The high-speed nature of the sport puts dogs at risk of injury or death.
- Lack of regulation: Inconsistent regulations across states and countries have led to concerns about the sport’s accountability.
As you navigate the complex world of greyhound racing, it is crucial to weigh these ethical concerns and form your own opinion on the matter.

Prices of goods are inflating fiercely! We’ve got roaring gas prices and fire-breathing prices for commodities. Even if we slave all day and work extra shifts, some of us just can’t cope with the rising economic changes. It’s not just private citizens or the workforce affected by the massive price increase. These economic changes affect big-time corporations, small businesses, and wholesale suppliers. Since the masses cannot proactively cope with the inflating prices of goods and services, companies need to adjust. Food prices have increased, and some have decreased in serving sizes. Other companies have adjusted their work hours because rental space prices have increased. All persons are affected by the massive change in the global economy.
Since it is getting more challenging to cope with the changes brought by inflation, entrepreneurs like yourself must learn to adapt to the economic adjustments. Now, on the note of rising prices, businesses of all sizes must adjust to the economic changes. Businesses such as startup companies have the power to change how prices may lower. In this article, you will learn how you can work on achieving better sales. Despite the massive increase in prices, businesses, from a collective perspective, may be able to push the country’s economic standing to a better level.

In a Nutshell
What is Inflation?
Inflation measures price increases for a set of goods or services for a particular period. Inflation contributes to an unprecedented change in the economic instability of a country. Some countries go through phases of scarcity and extreme economic decline brought about by inflation. Though inflation isn’t a behemoth by nature, as it is a monetary phenomenon, it still contributes to how individuals and companies function in society. The colossal effect of inflation drives companies and individuals to work harder and cope with economic changes.
You can imagine how increasing inflation creates a plutocratic state with a societal divide that makes a state more fragile than it is. A Fragile State or Failed State is a political terminology that describes how a state has inevitably fallen into an economic depression that inhibits them from performing effectively and obtaining their needs, reaching an ultimate collapse.
On the other hand, some countries have a remarkable history of going from rags to riches. These countries are Switzerland and Singapore, which had to undergo extreme economic challenges to achieve their country’s goal of prosperity. These countries have worked towards achieving a lucrative method to reach their goals. Some of the methods they invested in include the development of manufacturing industries and shaping their own Gross Domestic Product (GDP).
Gross Domestic Product in Economics measures the value added to a product produced locally. GDP is a vital indicator of a country’s economic performance. The most significant GDP contributor in the Philippines is the agricultural sector, with the private sector as it comes second. The private sector consists of private companies in different industries. The most prominent industry among these private sectors includes retail, food and beverage, and innovative initiatives such as eCommerce.
You can choose between two things if you feel troubled as an entrepreneur. Give up and admit defeat, or rise and keep persevering. Feeling disheartened is part of achieving a prosperous business and economic standing. As you go about working on different strategies in your business amidst the rising inflation rates, may gain the inspiration to work smartly.
What is the Correlation between Commodities and Inflation?
Commodities like agricultural goods, gas, minerals, precious metals, oil, and energy are directly affected by external factors that may result in an economy’s inflation or deflation. Economic fluctuations in recent years have been more rampant than they used to be before the 21st century. Despite this, you must also learn that commodities alone are not the single indicator of economic inflation.
How all these affect businesses in different industries is related to how consumers will behave according to the changes in the economy. If the cost of commodities is higher, companies will have to adjust their offers in terms of price, number, or price. For example, if the cost of gasoline increases, so will other goods and services that use gasoline, whether in production or transportation. For a company that sells bread, they may be affected by the inflation of gasoline costs which will make them raise their prices or offer fewer loaves of bread for the same price.
This is one of the things entrepreneurs must observe to serve their respective markets better. Part of running a business is observing the different fluctuations in the economy. Though we cannot predict how the economy will turn out daily, what we have control of are the business strategies that we set according to the observations and research we have made. If we can create a comprehensive analysis of how the market has been performing in a range that covers a two to three-month period, then we have a higher chance of creating plans that are effective for the performance of our business.
Compared to starting from nowhere or beginning plans on a whim, having a gauge of the activities of the market will make our plans more connected to our goals. As we work on the market analysis, we are also drawn more closely to getting to know the market we serve. When we have a general idea of how our market performs, we gain a better understanding of learning the ways that make our business products or services more personalized according to their needs.
How does Inflation Erode Our Monetary Power?
Have you gone to the market lately? Have you noticed how much less you could purchase from frequent stores? It seems like we have the same budget for our expenditures, but we cannot buy the same goods as we used to. For example, before inflation, you had enough to buy food for cooking, shampoo, soap, laundry products, and snacks. Now, your money can only go as far as buying food for cooking, shampoo, soap, and a cheaper option for laundry products. Farewell, snacks! Farewell, aromatic fabric conditioner!
Our ability to purchase goods and services declines as prices skyrocket. The gradual rise in prices erodes the power of our money. It’s frustrating to think about working extra because we have to cope with the numerous economic changes. It feels handicapping to resort to different methods to earn money. Businesses may perform better by offering reasonably priced products or services to encourage customers to purchase their products or services.
As inflation continues to rise, our money can only go as far as purchasing goods in a lower quantity. Inflation decreases the value of our money as time goes on. If we look back and imagine having 100 Pesos to spend, and we’re in the 90s – we could buy many things already. We can buy groceries, pay bills, ride public transportation, and still have some change to spare. Now, our 100 Pesos can only go as far as purchasing a liter of gasoline at a local gas station, and sometimes it still wouldn’t be enough.
Elasticity and Pricing
Given the economic changes, it wouldn’t be surprising if inflation continued in the next couple of years. Entrepreneurs have devised countless ways to work around inflation without running their profits down the drain. A classic mitigation method that entrepreneurs have worked on is raising prices and matching these higher prices with marketing strategies. This way, individuals will not feel as discouraged about the cost of purchasing a particular product or service.
However, despite entrepreneurs’ newly adopted mitigation strategies, individuals can only enjoy these methods for a short period. Intellectual users will grow tired of hearing and witnessing the same old strategy repeated by different brands. On this note, entrepreneurs become even more troubled as their marketing methods no longer entice the public audience.
On the contrary, because there are different mediums and technologies that entrepreneurs and consumers can use, the agility towards combating inflation becomes even more progressive. Through the technological advancements available in the present day, entrepreneurs can obtain information such as statistics about how users perform at a given time and towards a given marketing strategy. Entrepreneurs and managers must devote reasonable effort to analyzing their consumers’ behavior to cope continuously with the vastly changing economic realities.
Recalibration of business options against inflation is another action method that needs attention. To recalibrate one’s business strategies means producing relevant branding and pricing strategies and creating plans for inclusive consumption for the public audience. Recalibration also involves implementing profitable offerings that may include appropriate promos according to consumers’ behavioral economics. In this method, entrepreneurs must be wary of consumers’ desire for quantity and quality products or services. Consumers will not simply expel their money on offers without receiving a better quality or a larger quantity of a product or service.
What is a Recession?
This economic phenomenon, referred to as “recession,” is the decline of economic activity for a significant period. A recession usually lasts for months, creating critical changes in the Gross Domestic Product (GDP), employment, income, industrial production, international trade, retail sales, and digital trade. Economic recession is often a result of economic instability from calamity, inflation, unemployment, or other financial and societal issues. When people cannot obtain quality employment, there will be no earnings to use over expenditures.
One example of an economic recession is found during the height of the COVID-19 pandemic when people were prohibited from lurking in the outside world. Jobs involved in public transportation have experienced a struggle to cope with the changes brought by the COVID-19 pandemic, creating a recession in their economic face. On a larger scale, when a country falls into an economic recession, that country will experience weaker spending power.
When the masses have weaker spending power, companies will experience fewer sales, and some may result in closing their businesses. Aside from sharing a pandemic and inflation, other factors affect the economy and create a recession. You can anchor from the word recession that there is the word “recess,” Unlike your favorite subject back in grade school and high school, a recession is nothing more than a struggle for people and businesses. Some of the factors that create recession include…
- Industrialization and Technologization
While newly invented technologies help in productivity, other adverse effects are brought by technologization. Industrialization also involves using more machinery, decreasing the need for employed workers. Some of the impacts of automation aren’t limited to employment and corporate affairs alone. Some of the adverse effects of industrialization are on the environment, causing more extensive and unwanted changes to the ecosystem.
Despite having good inventions that aid in producing goods and services, another machinery is not helpful to the environment. These machinery that emits greenhouse gasses are also contributing to the climate crisis. The climate crisis is an urgent matter that needs to be addressed soon. Having scarce resources brought about by forest fires and floods is nothing we would want as entrepreneurs and human beings. Even the air we breathe gets polluted by the excess carbon dioxide produced by machinery.
Back in history textbooks, the breakthroughs brought about by industrialization have also caused employment to decline. During the 19th century, when technology and manufacturing equipment grew, labor was given a downtime. In the American Industrial Revolution, dating back to the 18th to 19th centuries, industries were dominated by the immersed amount of machinery. Despite the fast-paced changes brought about by industrialization, some populations in lower economic classes could not cope.
From industrialization, employment, and climate efforts – we are brought to the understanding that each action we do is, in one way or another, intertwined with how our future will turn out. With the reality of inflation that we face in writing, we must learn to work around understanding how better we can cope with these social phenomena without depreciating the value of our work and without staggering our customers.
- Excess Inflation
Can you imagine if prices just continue to rise by the day? Even if we had trillions of dollars in our pockets, we still wouldn’t be able to cope with these changes. The continued rise of inflation affects the population of the middle to lower economic classes. These phenomena affect how our everyday lives function, as each course is inevitably affected and interconnected, whether similar or different. When working masses are unable to cope with rising inflation, conglomerates and types on top are unable to obtain quality work, forcing them to provide higher compensation for their employees.
Excessive inflation isn’t limited to the lowering of individuals’ purchasing power. Continuous inflation also lowers treasury notes, pensions, savings, and benefits from companies and the government. Inflation contributes to the different variables of the economy and people’s way of life. Businesses across various industries must develop new ideas to cope with rising inflation. Otherwise, these businesses will be built upon high prices and poor marketing strategies that customers will not be fond of.
- Excess Deflation
Right off the bat, “Deflation” is the decrease in price across all forms of goods and services. You might think this is the solution against inflation, as though deflation were the protagonist in saving an economy from a crisis. However, you’d be surprised to know that deflation works similarly to inflation. Excess deflation may cause a supply shock as goods and services will be priced at cheaper rates. Compensation also deflates with cheaper costs of goods, services, and labor.
- Economic Shock
This phenomenon refers to the fundamental change in the different variables of macroeconomics. Economic shocks result in outcomes including and not limited to unemployment, inflation, deflation, economic recession, and others. An economic shock is usually a result of an economic societal event that creates a lasting change in the current economic pattern of a country. These unpredictable events greatly influence how a country’s economy may or may not thrive. One example of a phenomenon that created an economic shock is the COVID-19 pandemic. The ongoing health hazard has made a massive leap in the global economic scale, ranging from deflation to inflation.
- Extreme Economic Debt
Some countries, due to different societal and economic changes, resulting in extreme economic debt. While other countries are able to survive and thrive in a highly competitive market alongside countless societal issues, some countries engage in acquiring debt from neighboring countries. One country that has encountered extreme economic debt is the Philippines, garnering a total of Php 12.7 trillion.
While the Philippines isn’t a loner at having an extreme economic debt, countries like the Philippines are also working on investments and the increase of their gross domestic product. One of the primary industries that contribute to the Philippines’ economic growth is the private sector – namely the Philippines’ overseas Filipino workers (OFWs), the agricultural industry, and the recently booming retail industry, which includes startup and eCommerce companies.
Through these strategic investments by Philippine entrepreneurs, the Philippines is able to accelerate its economy at a competitive rate with other countries. The industries that help the Philippine economy grow better include the startup companies that have emerged in recent years. These new players in Philippine economics are no “new money” they are well-informed and aggressive businesses who offer a great deal to the table.
Focus on What You Can Control an Entrepreneur
From a global perspective, entrepreneurs have been restless about feeling deep concern for the environment and society as a whole than their businesses as a singular aspect. When reality strikes, enterprises are not only affected by a single hit; companies are involved through their manpower, their resources, their expenditures, and other factors. While some of these factors are included in the list of things entrepreneurs can control, some elements are those that cannot be owned by entrepreneurs – no matter the size or strength of their company or team.
There’s no worry about controlling what you can as long as it’s within the scope of your business. Some of these factors that can be included among the things you can control can be your marketing strategy, your virtual office, or perhaps your logistics platform. If you feel that having a physical store constructed for your business isn’t something that you would want to invest in, then perhaps you can try creating a partnership with a reliable eCommerce company that specializes in digital procurement. One notable company that you should consider is Shoppable Business. The company is designed to be at the service of entrepreneurs. Shoppable Businesses place businesses like yours front and center, connecting you with your target market in the easiest way possible.
As you focus on working with the things you can control, this is also the time when you let go of the things that fall beyond your control. “There’s no use crying over spilled milk!” If something can’t be helped, then you focus on the matter that needs your attention the most. Ask yourself about the technicalities, such as “how much time can I work on making this better?” Ask yourself questions like “what resources do I use to make this project work?” As you go along your journey to attending to these matters, see to it that you still work alongside your schedule so that you won’t fall behind your goals.
Other than what is mentioned above, if you are looking to grow your business, then you must be able to strike the right balance in attending to the matters you need to work on and those that are set to drive your goals to tip-top shape. One of the things you can control is the opportunities you take and those that you let go of. Some options come along your way to make you think. Not all the opportunities that knock on your door are opportunities that are good for you. As discussed, these are some of the things that you can control as an entrepreneur.

The rise of smartwatches has revolutionized the way we stay connected, track our fitness, and manage our daily lives. One of the key features that set smartwatches apart from their traditional counterparts is their ability to connect to cellular networks using a SIM card. But have you ever wondered how a smartwatch works with a SIM card?
The Basics Of Smartwatch Connectivity
Before we dive into the inner workings of a smartwatch with a SIM card, it’s essential to understand the different ways a smartwatch can connect to the internet and communicate with other devices.
Smartwatches can connect to the internet using:
- Wi-Fi: Smartwatches can connect to Wi-Fi networks, allowing them to access the internet and sync data with paired devices.
- Bluetooth: Smartwatches can connect to devices using Bluetooth, enabling features like music streaming and notification relay.
The Role Of A SIM Card In A Smartwatch
A SIM (Subscriber Identity Module) card is a small, removable card that stores information about a user’s subscription and identity. In the context of a smartwatch, a SIM card enables the device to connect to a cellular network, allowing users to make and receive calls, send and receive texts, and access data services like 3G or 4G.
The SIM card in a smartwatch performs several critical functions:
- Activates the cellular connection: The SIM card authenticates the smartwatch with the carrier’s network, enabling the device to connect to the cellular network.
- Stores subscriber information: The SIM card stores information about the user’s subscription, including their phone number, account details, and usage limits.
- Handles data transmission: The SIM card facilitates data transmission between the smartwatch and the cellular network, enabling features like email, social media, and music streaming.
Types Of SIM Cards Used In Smartwatches
Smartwatches use different types of SIM cards, each with its unique features and advantages:
eSIM (Embedded SIM)
An eSIM is a rewritable SIM card that is embedded directly into the smartwatch’s motherboard. eSIMs are tamper-proof, reducing the risk of SIM card theft or misuse. They also offer more storage capacity, enabling users to store multiple profiles and subscriptions.
physical SIM (pSIM)
A physical SIM, also known as a nano-SIM, is a traditional SIM card that is inserted into a slot on the smartwatch. pSIMs are more common and offer greater flexibility, as users can swap SIM cards or change carriers easily.
iSIM (Integrated SIM)
An iSIM is a hybrid of eSIM and pSIM. It’s a SIM card that’s integrated into the smartwatch’s processor, offering the security and storage benefits of an eSIM while still allowing users to swap SIM cards if needed.
How A Smartwatch With A SIM Card Works
Now that we’ve discussed the role of a SIM card in a smartwatch, let’s examine how a smartwatch with a SIM card works:
When a smartwatch with a SIM card is turned on, it searches for available cellular networks in the area. Once it finds a compatible network, the SIM card authenticates the smartwatch with the carrier’s system, establishing a cellular connection.
The smartwatch then uses the cellular connection to transmit and receive data, including voice calls, text messages, and internet data. The SIM card handles data transmission, ensuring that the smartwatch stays connected to the cellular network.
With a cellular connection established, the smartwatch can access a range of apps and services, including:
- Voice assistants like Siri or Google Assistant
- Messaging apps like WhatsApp or Facebook Messenger
- Email clients like Gmail or Outlook
- Social media apps like Instagram or Twitter
These apps can function independently, using the cellular connection to send and receive data, without the need for a paired smartphone.
Advantages Of A Smartwatch With A SIM Card
A smartwatch with a SIM card offers several advantages over traditional smartwatches or fitness trackers:
Fitness tracking without a phone: With a cellular connection, users can track their fitness activities, receive notifications, and stream music without the need for a paired smartphone.
Improved safety: In emergency situations, a smartwatch with a SIM card can make voice calls or send texts, even if the user’s phone is out of reach.
Enhanced convenience: Users can receive notifications, control their music, and access apps on their wrist, freeing them from the need to constantly check their phone.
Challenges And Limitations Of Smartwatches With SIM Cards
While smartwatches with SIM cards offer numerous benefits, they also come with some challenges and limitations:
Smartwatches with SIM cards may not be compatible with all carriers or networks, which can limit their functionality.
Data Costs And Billing
Using a smartwatch with a SIM card can result in additional data costs, as users may need to pay for a separate data plan or add-on to their existing plan.
The constant use of cellular connectivity can drain the smartwatch’s battery, reducing its overall battery life.
A smartwatch with a SIM card is a powerful device that offers a range of features and benefits, from fitness tracking to app functionality. By understanding how a smartwatch works with a SIM card, users can unlock the full potential of their device and stay connected, active, and informed on-the-go. As the technology continues to evolve, we can expect to see even more innovative features and applications emerge, further blurring the lines between smartwatches and smartphones.
What Is A SIM Card And How Does It Work In A Smartwatch?
A SIM card, or Subscriber Identity Module, is a small microchip that stores data used to identify and authenticate a user’s subscription on a cellular network. When inserted into a smartwatch, the SIM card allows the device to connect to a cellular network, enabling features like making and receiving calls, sending texts, and accessing data. This means that a smartwatch with a SIM card can function independently of a paired smartphone, giving users more freedom and flexibility.
In addition to storing user data, a SIM card also contains a unique identifier called the International Mobile Subscriber Identity (IMSI), which is used to authenticate the user’s subscription. When a smartwatch with a SIM card is turned on, it sends a request to the cellular network, and the network verifies the IMSI to ensure the user has a valid subscription. Once authenticated, the smartwatch can access the network and use its features.
How Does A Smartwatch With A SIM Card Differ From One Without?
A smartwatch with a SIM card offers more functionality and independence compared to one without. With a SIM card, a smartwatch can connect to a cellular network, making it possible to make and receive calls, send texts, and access data even when not paired with a smartphone. This is particularly useful for users who want to use their smartwatch during outdoor activities like hiking or running, where carrying a phone may not be practical.
On the other hand, a smartwatch without a SIM card relies on a paired smartphone to access these features. It can still track fitness and health metrics, receive notifications, and control music playback, but it will not be able to connect to a cellular network or make/receive calls and texts independently. This makes a smartwatch with a SIM card a more attractive option for users who want a more comprehensive wearable experience.
Can I Use Any SIM Card With My Smartwatch?
Not all SIM cards are compatible with every smartwatch. The type of SIM card required depends on the specific smartwatch model and its supported frequency bands. Some smartwatches may require a nano-SIM, while others may use an eSIM or micro-SIM. Additionally, some smartwatches may only support specific cellular networks or carriers, so it’s essential to check compatibility before purchasing a SIM card.
It’s also important to note that some smartwatches may have specific requirements for the SIM card’s size, shape, or material. For example, the Apple Watch uses an eSIM, which is embedded directly into the device, while Samsung smartwatches may use a nano-SIM. Be sure to check the manufacturer’s specifications before selecting a SIM card for your smartwatch.
How Do I Activate A SIM Card On My Smartwatch?
Activating a SIM card on a smartwatch typically involves a few simple steps. First, ensure that the SIM card is compatible with your smartwatch and that you have a valid subscription with a cellular carrier. Next, insert the SIM card into the smartwatch’s SIM card slot, usually located on the side or back of the device. Then, follow the on-screen instructions to activate the SIM card and set up your cellular service.
The specific activation process may vary depending on the smartwatch model and carrier. Some smartwatches may require you to scan a QR code or enter an activation code provided by the carrier. Others may prompt you to download and install a special app to activate the SIM card. Be sure to follow the manufacturer’s instructions and any additional guidance provided by your carrier.
Can I Use My Smartwatch With A Different Carrier?
In most cases, you can use your smartwatch with a different carrier, but there are some limitations to consider. If you have an unlocked smartwatch, you can typically use it with any carrier that supports the device’s frequency bands. However, some smartwatches may be locked to a specific carrier or region, which can limit your options.
If you plan to switch carriers, be sure to check the new carrier’s compatibility with your smartwatch. You may need to purchase a new SIM card or activate your existing one on the new carrier’s network. Additionally, some features or apps may not be available on the new carrier, so it’s essential to research and compare carrier plans before making a switch.
How Much Data Does A Smartwatch Use?
The amount of data used by a smartwatch with a SIM card depends on various factors, including the type of activities you use it for, the frequency of usage, and the specific features enabled. On average, a smartwatch can use between 10MB to 50MB of data per month for basic tasks like receiving notifications, tracking fitness metrics, and making occasional phone calls.
However, if you use your smartwatch for more data-intensive activities like streaming music, watching videos, or using GPS navigation, your data usage can increase significantly. To minimize data usage, consider adjusting your smartwatch’s settings, disabling unnecessary features, and using Wi-Fi whenever possible. You can also monitor your data usage through your carrier’s website or mobile app to stay within your monthly data allowance.
Can I Use A Smartwatch With A SIM Card Internationally?
Yes, you can use a smartwatch with a SIM card internationally, but be aware of the potential roaming fees and limitations. If you plan to travel abroad, check with your carrier to see if they offer international roaming services and what the associated fees are. Some carriers may offer special international plans or add-ons that can help reduce roaming fees.
When traveling abroad, ensure that your smartwatch is compatible with the local frequency bands and that you have a valid SIM card or international roaming plan. Keep in mind that not all features may be available when roaming internationally, and data speeds may vary depending on the local network. To avoid unexpected charges, consider purchasing a local SIM card or using Wi-Fi whenever possible. | <urn:uuid:7978f789-7701-4735-a7e9-cb67fb3b40da> | CC-MAIN-2024-51 | https://thetechylife.com/how-does-a-smartwatch-work-with-sim-card/ | 2024-12-09T04:27:55Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066460657.93/warc/CC-MAIN-20241209024434-20241209054434-00700.warc.gz | en | 0.912242 | 2,413 | 2.875 | 3 |
The Philosophy of Life is a concept that has intrigued humanity for centuries. But what does it actually mean? In essence, it refers to a set of beliefs and principles that guide how we perceive life, our place in it, and our actions. The philosophy of life isn’t just a theoretical idea; it directly impacts the way we live, influencing our choices, behavior, and happiness.
Many people search for a deeper meaning in their lives, hoping to find clarity and direction. This search for meaning is where the philosophy of life comes in. It helps us navigate life’s complexities and find a sense of purpose, which is essential for a fulfilling existence.
Understanding the Philosophy of Life:
Defining the Concept of Life Philosophy
The Philosophy of Life is about identifying what truly matters to you. It’s not just a list of rules but a guiding principle that shapes your worldview. It helps you understand why you do what you do, whether it’s pursuing a career, building relationships, or simply enjoying the moment.
How Philosophy Shapes Our Perspectives?
Our philosophy of life influences how we react to challenges, success, and failure. For instance, if you believe that life is about constant growth, you’re more likely to view setbacks as learning experiences rather than roadblocks. Thus, having a solid philosophy can change your mindset and lead to a healthier, more positive approach to life.

Core Principles of the Philosophy of Life:
The Pursuit of Meaning and Purpose
At its core, the Philosophy of Life often revolves around the search for meaning. Without a clear sense of purpose, life can feel directionless. By identifying what drives you—whether it’s helping others, achieving personal success, or exploring creativity—you can find more satisfaction in daily living.
The Value of Self-Reflection and Awareness
A critical part of developing a life philosophy is practicing self-reflection. Regularly taking time to assess your beliefs, actions, and emotions can lead to greater self-awareness. This helps you align your life with your values, ultimately leading to a more meaningful existence.
How to develop your own Life Philosophy?
Step 1: Identifying Your Core Values
Start by understanding what matters most to you. What are your non-negotiables in life? For some, it’s integrity and honesty; for others, it’s freedom and adventure. Once you pinpoint these values, use them as a compass to guide your decisions.
Step 2: Embracing Personal Growth
The Philosophy of Life isn’t set in stone—it evolves as you grow. Embrace change and be open to new experiences. Personal growth leads to a deeper understanding of yourself and the world, helping you refine your life philosophy over time.
Impact of Life Philosophy on Mental Well-being
How Philosophy helps in overcoming challenges?
Life is full of unexpected twists and turns. By having a solid philosophy, you develop resilience. When things don’t go as planned, your guiding principles can provide comfort and clarity, helping you navigate tough situations with grace.
Role of Philosophy in Reducing Anxiety and Stress
Philosophy encourages us to focus on what we can control and let go of what we can’t. This mindset is particularly useful in reducing anxiety. By accepting the impermanence of life, you can reduce stress and focus on living in the present moment.
Philosophy of Life in Different Cultures:
Eastern Perspectives: Buddhism and Taoism
In Buddhism, the philosophy of life is centered on the Four Noble Truths and the Eightfold Path, emphasizing the impermanence of life and the importance of inner peace. Similarly, Taoism promotes living in harmony with the Tao (the way of nature), which leads to a balanced, fulfilling life.
Western Perspectives: Stoicism and Existentialism
Stoicism teaches resilience through acceptance of life’s hardships, focusing on virtue and wisdom as the keys to happiness. On the other hand, Existentialism emphasizes individual freedom and the responsibility of shaping one’s own life path, regardless of inherent meaninglessness.
Role of Philosophy in Decision-Making:
How Philosophy guides Choices and Actions?
Your Philosophy of Life influences your decisions by aligning them with your values. For instance, if you value kindness, you’ll likely choose actions that promote empathy and compassion. Philosophy helps you stay true to yourself, even in difficult situations.
Examples of Philosophical Decision-Making in Real Life
Philosophical principles have real-world applications. For instance, in business, ethical decision-making rooted in integrity can lead to long-term success. In personal life, prioritizing meaningful connections over superficial pursuits can result in lasting happiness.
Applying Life Philosophy in Daily Living:
Practicing Mindfulness and Presence
One of the most powerful ways to embody your Philosophy of Life is to practice mindfulness. This simply means being fully present in whatever you are doing. Whether you’re eating, walking, or working, being present allows you to truly engage with the moment, reducing stress and enhancing your enjoyment of life.
Mindfulness is not just a meditative practice—it’s a way of life. When you focus on the present, you stop worrying about the past or future. This shift in mindset can lead to more fulfilling relationships, better mental health, and a deeper appreciation for the small joys of everyday life.
Building Meaningful Relationships
The quality of your relationships significantly influences your overall life satisfaction. By adopting a life philosophy centered around empathy, kindness, and understanding, you can build deeper, more meaningful connections with others. Genuine relationships provide a sense of belonging and purpose, helping you navigate life’s ups and downs.
A well-developed Philosophy of Life teaches us that people are at the heart of our experiences. When we prioritize strong, positive relationships, we create a support network that enriches our lives and fosters growth.
Connection between Philosophy and Happiness:
Understanding True Happiness Through Philosophy
Happiness is often misunderstood as a fleeting emotion. However, the Philosophy of Life encourages a deeper, more sustainable approach. Philosophers like Aristotle believed that true happiness, or “eudaimonia,” comes from living a virtuous life and fulfilling one’s potential.
When you align your actions with your values, you experience a sense of fulfillment that goes beyond temporary pleasure. By focusing on personal growth, meaningful relationships, and purpose-driven living, you create a foundation for lasting happiness.
How Life Philosophy can lead to lasting fulfillment?
Fulfillment is about living a life that feels right to you, not necessarily one that meets societal expectations. When you develop your own Philosophy of Life, you give yourself permission to pursue what genuinely matters. This personal fulfillment leads to a deeper sense of contentment and inner peace.
Common Philosophical Questions to Ponder:
Nature of Existence and Reality
One of the biggest questions in the Philosophy of Life is about existence itself. What does it mean to truly live? Are we just biological organisms, or is there a deeper purpose? Philosophers like Descartes pondered the nature of reality, while modern thinkers explore concepts like simulation theory. These questions, though they may not have definitive answers, can help us reflect on our place in the world.
Exploring the concept of Free Will
Do we have control over our choices, or are we simply products of our environment and genetics? The debate between free will and determinism has been ongoing for centuries. Understanding where you stand on this topic can shape your Philosophy of Life and guide how you approach decision-making.
Challenges in developing a Philosophy of Life:
Overcoming Doubt and Uncertainty
Creating a solid Philosophy of Life isn’t always straightforward. Doubts and uncertainties are natural, especially when confronting deep existential questions. However, these challenges are part of the journey. Embrace the unknown as an opportunity for growth and exploration rather than a source of fear.
Embracing Impermanence and Change
Life is constantly changing, and clinging to old beliefs can hold you back. A flexible philosophy allows you to adapt to new experiences without losing your core values. Embracing change doesn’t mean abandoning your beliefs but rather refining them as you gain new insights.
How famous Philosophers viewed Life?
Insights from Socrates, Nietzsche, and Thoreau
Throughout history, many philosophers have offered profound insights into the Philosophy of Life. Socrates famously said, “The unexamined life is not worth living.” He emphasized the importance of self-reflection and questioning one’s beliefs. Nietzsche, on the other hand, encouraged people to embrace life’s challenges and create their own meaning, famously proclaiming, “What doesn’t kill you makes you stronger.”
Henry David Thoreau, through his work “Walden,” promoted the idea of living simply and intentionally. His philosophy revolved around the idea that a meaningful life isn’t about accumulating possessions but about experiences, self-discovery, and nature.
Lessons we can learn from Great Thinkers
The wisdom of these philosophers reminds us to question, explore, and continuously seek our own truths. Whether it’s through the stoic resilience of Marcus Aurelius or the existential courage of Sartre, there’s always something to learn from those who’ve come before us.
Living a Purpose-Driven Life:
Power of Setting Life Goals
Living with purpose is at the heart of any effective Philosophy of Life. Setting clear goals gives you direction and motivates you to move forward. Whether these goals are related to your career, personal growth, or relationships, having a vision of where you want to go helps you live more intentionally.
Aligning Actions with Your Life Philosophy
It’s not enough to simply state your beliefs—you need to act on them. If your philosophy emphasizes compassion, look for opportunities to help others. If it focuses on self-growth, commit to lifelong learning. Aligning your daily actions with your values makes your philosophy a living, breathing part of your life.
How to evolve your Life Philosophy over time?
Continuous Self-Improvement and Adaptation
Your Philosophy of Life isn’t a fixed set of rules; it’s a dynamic guide that evolves as you grow. Life experiences, new insights, and even challenges can reshape your beliefs. Be open to change and view it as an opportunity for deeper understanding.
Role of Life Experiences in Shaping Philosophy
Every experience, good or bad, contributes to your Philosophy of Life. Mistakes, failures, successes—they all teach valuable lessons. By reflecting on these experiences, you gain clarity on what matters and refine your guiding principles.
The journey to discovering your Philosophy of Life is lifelong. It’s not about having all the answers but about asking the right questions. By continuously exploring your values, reflecting on your experiences, and staying open to change, you can develop a philosophy that leads to a meaningful, fulfilling life. Remember, life is not just about existing—it’s about living with purpose and intention.

This guidance deals with discrimination in the workplace. It looks at your rights as an employee or worker and, the steps you can take if you feel you are being treated unfairly or may be the victim of unlawful discrimination. The RCN also has a range of resources on equality, inclusion and human rights, that may be of assistance.
The Equality Act 2010 (the Act) applies in England, Scotland and Wales. The Equality Act 2010 was not enacted in Northern Ireland and the further information section below explains this further.
The Act protects people from discrimination on the basis of what are termed “protected characteristics” which are listed below:
- gender reassignment
- marriage and civil partnership
- pregnancy and maternity
- religion or belief
- sexual orientation.
Under the Equality Act 2010, it is unlawful to discriminate against someone because of a protected characteristic. The Act covers the whole spectrum of employment including recruitment, training, promotion, terms and conditions, redundancy, discipline and dismissal. Individuals are protected from discrimination in a number of contexts including employment, access to goods and services, education and housing.
The principles also apply to ‘workers’ in general (rather than simply ‘employees’) meaning that you are protected from discrimination if you are a bank or agency worker.
RCN Nursing Workforce Standards
The RCN Nursing Workforce Standards are designed to support a safe and effective nursing workforce alongside each nation’s legislation. They include guidance on workforce planning and rostering, as well as staff health, safety and wellbeing. Standards 12 states that the nursing workforce should be treated with dignity, respect, and enabled to raise concerns without fear of detriment, and to have these concerns responded to.
This when you are treated less favourably on the grounds of your protected characteristic. For example, not employing a nurse because they are of African origin.
Discrimination by association
Discrimination against someone because of their connection/association with someone with a protected characteristic is called discrimination by association. For example, someone is dismissed because they have had to take time off to care for a disabled relative, even though colleagues with similar or higher levels of absence have not been disciplined for taking time off.
Discrimination by perception
Discrimination against someone because they are perceived to possess a protected characteristic. For example, not employing a nurse because the employer (mistakenly) believes the nurse to be gay.
Where a provision, criterion or practice, puts someone with a protected characteristic at a disadvantage, when compared to others who do not share the same characteristic. It may be possible for an employer to justify indirect discrimination on the grounds that the activity in question was objectively justifiable, as a proportionate means of achieving a legitimate aim.
Harassment is unwanted conduct that is related to a relevant protected characteristic, and the conduct has the purpose or effect of violating a person's dignity or creating an intimidating, hostile or degrading, humiliating or offensive environment. For example, being subject to abuse because you are undergoing gender reassignment.
Where you are subject to detrimental treatment because you have undertaken a ‘protected act’. This includes making a claim or complaint of discrimination under the Act or helping someone else to make a claim by giving evidence or information for example, during a disciplinary process.
If you are experiencing discrimination, you should firstly read your employer’s equality and diversity policy and speak to your line manager about your concerns. It may be helpful to read our sections below explaining in more detail the types of discrimination protected under the Equality Act.
If you are not satisfied with your manager's response, you should contact us.
If you need emotional support, contact us. Our counselling team may be able to help you.
Under the Equality Act 2010, it can be unlawful for an employer to discriminate against a worker because of their age.
Direct and indirect discrimination can arise in a number of circumstances:
- how an employer selects new staff, for example, they cannot state in an advertisement that the post must be filled by a person of a particular age
- refusing to offer, or deliberately not offering, a person employment on the grounds of age
- the terms offered by an employer to a person in employment, on the grounds of age
- not giving a promotion, transfer, training or any other benefit on the grounds of age
- dismissing an employee or subjecting them to any other detriment on the grounds of age.
The default retirement age of 65 has been abolished and in future it will only be possible for employers to operate a compulsory retirement age provided this can be objectively justified as a proportionate means of achieving a legitimate aim. The Department for Work and Pensions has help and support for an older workforce. ACAS also has guidance on this area.
Justifying age discrimination
It may be possible for an employer to justify both direct and indirect age discrimination, on the grounds that the activity in question was objectively justifiable as a proportionate means of achieving a legitimate aim. It can be difficult to show that discrimination is justifiable and employers should take care in making judgements about someone’s ability to do a job based on their age.
Under the Equality Act 2010, it is unlawful for an employer to discriminate against a worker because they have a disability. Our advice guide on Disability and the Equality Act gives further information, including how to disclose disability to your employer and how to challenge disability discrimination.
We also have information in our Health Ability Passport guidance which provides detailed information on reasonable adjustments.
If you are being discriminated against, you should refer to your employer’s equality and diversity policy and speak to your line manager about your concerns. If you are unsatisfied with the response, contact us as you may wish to follow your employer’s grievance procedure with our support.
The Equality Act 2010 protects employees, prospective employees and those accessing vocational training from unfavourable treatment on the grounds of pregnancy and taking maternity leave. The law applies regardless of how long a person has been employed by their employer and you are protected to the end of your maternity leave (including additional maternity leave). Please also see our Having a family toolkit.
You do not have to tell a prospective employer that you are pregnant. The fact that you are pregnant should not be considered when determining who gets the job as it would be viewed as discrimination.
Informing your employer of your pregnancy
You must ensure you follow the correct processes when notifying your employer of your pregnancy. Once you have taken steps to inform your employer of your pregnancy you should not be subject to unfavourable treatment.
You will be entitled to maternity pay as provided for in your contract of employment and any salary increases that occur while on maternity leave. Your employer must also inform you of any promotion opportunities and changes to your terms and conditions, including reorganisations.
Returning from maternity leave
You have a right to return to the job you had previously, with the same terms and conditions, when returning during or at the end of ordinary maternity leave of 26 weeks.
It is important to note that whilst section 18 of Act prohibits direct discrimination relating to pregnancy and maternity, it does not include discrimination by association or discrimination by perception.
ACAS have further detailed guidance on discrimination because of pregnancy and maternity.
Under the Equality Act 2010 it is unlawful to discriminate on the grounds of race. The Act says race can mean your colour, nationality, ethnic or national origins.
It is unlawful for an employer to give discriminatory terms of employment, deny promotion, training or transfer or withhold benefits, facilities or services on the grounds of race. Prospective employees are also covered by the Act.
Racism in the workplace
If a colleague or patient demonstrates racist behaviour, for example makes racist jokes, then raise this issue with your line manager. Racist jokes are offensive and can create a hostile working environment.
If you are experiencing discrimination, you should refer to your employer’s equality and diversity policy and speak to your line manager about your concerns. If you are unsatisfied with the response, contact us.
The Act makes it unlawful to discriminate against someone because of religion or belief.
Religion means any religion and a reference to religion includes a reference to a lack of religion. Belief means any religious or philosophical belief, including a lack of belief. However, if there is conflict between the philosophical belief and fundamental principles of human dignity, then it may not be protected. The Equality and Human Rights Commission website (for England, Scotland and Wales) have further guidance on religion or belief in the workplace.
For a philosophical belief to be protected under the Act it must be:
- genuinely held
- not an opinion or viewpoint based on the present state of information available
- a weighty and substantial aspect of human life and behaviour
- attain a certain level of cogency, seriousness, cohesion and importance
- be worthy of respect in a democratic society, not incompatible with human dignity and not in conflict with the fundamental rights of others.
Time off for religious observance
Your employer would have to prove that allowing you time off would be detrimental to services provided. If your line manager refuses reasonable changes to your work pattern without objective justification, this may be considered discrimination. You should discuss this matter with your line manager or human resource department in the first instance. If you require support please contact us.
The Act makes it unlawful for employers to discriminate because of their sex, male or female. It also covers those individuals who are proposing to undergo, are undergoing, or have undergone a process or part of a process for the purpose of reassigning the person's sex by changing physiological or other attributes of sex. It is not necessary for persons to be under medical supervision to affect their gender reassignment in order to be protected.
Persons diagnosed with gender dysphoria or gender identity disorder may also be protected under the disability discrimination provisions of the Act, as those condition may have a substantial and long-term adverse impact on their ability to carry out normal day-to-day activities.
Please also see the ACAS guidance on Gender reassignment.
You can also see our guide on Discrimination: equal pay which explains more on discrimination between men and women in the work place which can impact on pay and conditions.
Under the Equality Act 2010, it is unlawful to discriminate against someone because of their sexual orientation.
Homophobic abuse and jokes are not acceptable and your employer must take steps to protect you from harassment or abuse. If you are concerned about this you can obtain your employer’s dignity at work policy. You may wish to consider a grievance and if so, it is important that you contact us for further support.
Civil partnership and marriage
Under the Equality Act 2010, it is unlawful to discriminate against someone because they are married or in a civil partnership. This protection does not extend to persons who are not married or in a civil partnership or are single.
This specific protected characteristic does not attract the full range of protections as with other protected characteristics. For example, the act does not afford protection against discrimination by perception or association. There is also no protection from discrimination if a person is unmarried or single, cohabiting, widowed or divorced. However, harassment related to civil partnership might amount to harassment related to sexual orientation.
Visit the Equality and Human Rights Commission website (for England, Scotland and Wales) or Equality Commission Northern Ireland for more information on discrimination. Both of these organisations have produced a Code of Practice relating to employment, which is useful to consider if you feel your employer may not be acting correctly.
The Equality Act 2010 has not been adopted in Northern Ireland but there are two laws which promote equality of opportunity for people with disabilities by banning disability discrimination and which give enforceable legal rights to people with disabilities. The are the Disability Discrimination Act 1995 and the Special Educational Needs and Disability NI Order 2005.

We’re all different. Bodies change over time and there are lots of different body shapes.
This variety is normal and we are all attracted to different things – if we were all exactly the same, life would be pretty boring right?
Instead of comparing yourself to others, it’s more important to know what is normal for you - getting to know your body is really helpful and can make you feel more comfortable with what you have.
Knowing your body can help you spot things such as lumps and bumps that aren’t normal, making it easier to get help quickly when something isn’t right.
We suggest having a look, at different body parts regularly, sometimes with the help of a mirror for those areas that aren’t so easy to see.
For those with testicles, have a warm bath or shower to soften the scrotum (balls). Hold your scrotum in the palm of your hands and gently use the fingers and thumbs of both hands to examine for lumps or bumps. If you do come across a lump, do not be alarmed as this could be lots of different things, but it would be best to visit your GP to get it checked out.
For those with vulvas, take a look with a mirror and get to know it! Keep an eye out for any new lumps and bumps that might appear and keep an eye on changes to discharge and periods. If you are worried about anything unusual or strange, speak to a GP to get some support. Don't be embarrassed - whatever it is, they will have heard the same from other people, and will be able to help you with it.
For those with breasts, examine them using a flat palm pressing again the breast in different directions. Be sure to check all of each breast including the top and bottom and not just the surface. Keep an eye out for changes in shape and size, skin texture and colour of the nipple and surrounding area.
Puberty is a period of both physical and mental change for someone who is growing up and reaching sexual maturity.
These changes vary depending on gender and everyone goes through puberty at different ages and speeds. The average age for puberty to start is around 11-13 but lots of us will see changes start earlier or later than this.
During puberty, people with male sex organs may notice that their voice becomes deeper - sometimes referred to as your voice ’breaking’. Facial hair can also begin to grow as well as hair under the armpits, and on the legs, chest and private parts. The penis and testicles may grow or change shape and some may also develop 'man boobs' (technically known as Gaenocomastia).
In people with female sex organs, puberty can bring their first period. Boobs or breasts will also grow during puberty, and come in all shapes and sizes, including different size and colour nipples.
There are other body changes that can happen to anyone, including weight change, growth spurts and changes to the skin – which can become oily, greasy or spotty. Acne is also something that may happen during puberty and adolescence, and although it can make you feel self-conscious, it is extremely common and there are lots of different medications that a doctor can give you to help. For more info on acne, check out the NHS Choices website.
During puberty, many young people start getting sexual thoughts and begin exploring their bodies, using masturbation to start experimenting with what they do and don’t like.
For more info on puberty, visit these websites and search puberty for a variety of great articles:
Your gender identity is the gender you identify yourself as.
Gender identity doesn’t need to match your gender at birth, it can be something completely different. It also doesn’t come down to your clothes or style, it is about how you feel and who you are.
For example, someone may be born with a vulva but identify themselves as a boy or man. Someone can be born with a penis but identify as being a girl or a woman.
There are lots of different gender identities out there, so although the most common may be male or female, other people may identify as something else like polygender (you identify with multiple genders and may change from day to day) or non-binary (you don’t identify with being male or female).
Someone’s gender identity doesn’t determine their sexuality. Gender is who you are. Sexuality is who you are attracted to. See Sexuality, below, for more information.
Transgender is a term often used by people whose gender is different from their biological sex.
Transphobia is a term used when someone is afraid of, or prejudiced against transgender people and doesn’t believe in equality and inclusion for all genders. When someone is transphobic, they can cause hurt, upset and exclusion for people who fit into minority gender groups.
For more information, help and support around gender, contact LGBT Youth Scotland:
Your sexuality is who you are attracted to and, like gender, there are lots of ways that people identify themselves.
For example, if someone is attracted to the same sex they may identify as homosexual, gay or lesbian. People who are attracted to both males and females may identify as bisexual. Pansexual is also common and is when someone is attracted to a person because of who they are, rather than their sexuality or gender. When someone is attracted to the opposite sex they may identify as being heterosexual or ‘straight’.
Sexuality shouldn’t determine or limit what a person can do, or the opportunities that they have, such as getting a job, going to university or getting married.
Homophobia and biphobia are terms used for someone who has a fear of, or is prejudiced against those who identify as homosexual or bisexual. It is non-inclusive and makes people from minority sexuality groups feel excluded.
For more info, help and support for any questions you may have around sexuality, contact LGBT Youth Scotland:
Periods, otherwise known as menstruation, happen to those born with female reproductive organs. They start when someone reaches puberty and reaches sexual maturity, meaning their body is ready to make a baby.
Egg cells are produced in ovaries and are released in a cycle that repeats monthly, although exact cycles differ from person to person. The egg travels from the ovaries, through the fallopian tubes and into the womb for fertilisation. If the egg cell is not fertilised by sperm, it needs to leave the body so a new egg cell can start its cycle.
A period happens when the lining of the uterus (womb) sheds it’s lining to help carry the egg out of the body. Periods are made up of blood and tissue from the lining of the uterus, which leaves the body through the vagina.
Different people experience different kinds of periods. Some periods are light and last a few days, some last for a couple of weeks. Some are heavy with lots of blood, and those people might also get period pain or cramps in the lower abdomen. Some people have their period at the same time every month and some people have irregular periods.
Whatever kind of period you get, it’s important to know what is normal for you. Changes to your period can indicate health problems as well as other things. They can also be affected by stress, diet and major lifestyle changes.
If you are worried about a sudden change to your period, go and speak to a health expert for support. Changes could be an indication of an STI if you have had unprotected sex. Likewise, if you have had unprotected sex and missed a period, it could a sign that you are pregnant.
Tampons and sanitary towels are hygiene products used during your period. Sanitary towels are placed inside underwear to absorb any blood or tissue that leaves the vagina. Tampons are inserted into the vagina to absorb blood before it leaves the body. Many people can be anxious about using tampons, especially when they first start their period, and it is important to use the products you feel most comfortable using. Whichever product you use, it is important to change sanitary products regularly, and more often if you do get heavy periods.
Body hair usually starts to appear during puberty and grows in lots of different places - around the legs, private parts, armpits, chest, arms, back, face and neck.
Hair grows in different places for different reasons. Mainly, to act as a barrier to prevent infections getting into the body and to keep body parts at the right temperature.
Some people choose to shape their body hair or to remove it, by shaving, waxing or trimming areas like armpits, chest and legs. Whatever you decide to do with your body hair is your choice and for nobody else to decide.
When it comes to pubes, shaving or waxing can increase your chances of catching an STI. This is because shaving and waxing damages the surface of the skin, creating small cuts that allow infections to get into your body more easily.
Vulva is the word to describe the external parts of the female sexual organs.
Vulvas are made up of outer lips (labia majora), inner lips (labia minora) and the clitoris.
Vulvas come in lots of different shapes and sizes. They are all completely normal and make you unique! Some people worry about what their vulva looks like and whether it is ‘normal’. Sexualised media like porn has given us a very narrow view of what a ‘normal’ vulva looks like.
Lots of people think vulvas have to be small and compact, with labia minora being smaller than labia majora and neatly, or completely shaved. But, in fact, vulvas with bigger inner lips than outer lips are very common, and shape, texture and colour of labia minora varies from person to person.
The important thing to know about your vulva is whether or not it is normal for you. Get to know it, take a look with a mirror regularly and keep an eye out for any unusual lumps and bumps.
For more info about vulvas and labias, visit http://www.labialibrary.org.au
The vagina is the passage linking the vulva to the cervix and uterus (womb). The vagina is where a finger, penis or sex toy is inserted during sex and, during birth, a baby exits the body through the vagina.
Vaginas are amazing things! They produce natural lubrication when aroused to make sex easier and more comfortable. They also self-clean! If your vagina produces discharge (white fluid), this is completely normal and is your vagina cleaning itself. It is also completely normal for your discharge to vary at different times of the month. However, if you start experience unusual discharge when you don’t normally get any, or you get smelly, coloured discharge this could be a sign on an infection and you should seek medical advice.
Even though vaginas are great at self-cleaning, it is important to wash regularly. The skin around your vulva may be sensitive to perfumes and other ingredients found in soaps and shampoos. We recommend washing with warm water and non-perfumed products to avoid irritation. There is no need to put any products inside the vagina, just wash the external parts of the vulva.
Penises can be lots of different shapes and sizes. They can be straight or curved, short or long, circumcised or uncircumcised, and all things in between.
All of these differences are completely normal and may change through puberty.
A penis has lots of different parts to it, but basically there is the top (or ‘the head’) and ‘the shaft’. Inside the penis, there are tubes that link it to the bladder (for peeing) and the testicles (for semen).
The testicles or ‘balls’ are found inside the scrotum and are where sperm and semen are produced. Sperm are tiny cells which can impregnate an egg that is inside the womb – leading to pregnancy. Semen is a whitish liquid that carries sperm and help them travel to reach the egg. Testicles come in different shapes and sizes and it is common for one to hang lower than the other.
Penis and testicle sizes can also change depending on temperature.
When aroused, the penis becomes erect to prepare itself for sex. This is sometimes known as a hard on. It is normal to get erections at odd times, such as first thing in the morning, and they can be affected by pressures in your life, such as stress, tiredness and anxiety. Losing an erection at an awkward moment can happen to the best of us, but is completely normal. If you are worried about this, speak to your GP for further support.
It’s important to regularly check for lumps and bumps around the genitals. The head of the penis can be sensitive to perfumes and other ingredients found in soaps and shampoos, particularly under the foreskin. We recommend washing with warm water and non-perfumed products to avoid irritation. | <urn:uuid:6c662f46-ac42-472b-9b25-033e46e248de> | CC-MAIN-2024-51 | https://wavehighland.com/being-you/ | 2024-12-09T04:07:50Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066460657.93/warc/CC-MAIN-20241209024434-20241209054434-00700.warc.gz | en | 0.965321 | 2,746 | 3.1875 | 3 |
Are you looking to master the art of bucking trees with a chainsaw? If so, it's important to approach this task with a strong sense of safety. In this article, we'll cover the essential safety precautions you need to take to buck a tree with a chainsaw without risking injury or damage to your surrounding environment. By the end, you'll be ready to handle your chainsaw with confidence and skill. Let's get started!
Wear Protective Gear
One of the most important safety precautions when it comes to bucking trees with a chainsaw is wearing the right protective gear. This includes a hard hat, eye and ear protection, gloves, and chaps. A hard hat will protect your head from falling branches, while eye and ear protection will keep your senses safe from the noise and debris generated by the chainsaw. Gloves will help you grip the saw better and reduce the risk of vibration injuries, while chaps will provide a protective layer against the chainsaw. Remember, the equipment you choose should be specifically designed to protect you from chainsaw-related injuries.
Check Your Surroundings
Before you begin cutting, take a good look around your surroundings and identify any potential hazards. This includes power lines, buildings, vehicles, and people. Make sure you have enough space to work and that there are no obstacles in your way. If you're unsure about whether an object could pose a hazard, it's better to err on the side of caution and deal with it before starting your work. Be extra careful if you're cutting on a slope or uneven ground – it's easy to lose your balance and slip, especially when wielding a chainsaw.
Use Your Chainsaw Correctly
Knowing how to use your chainsaw correctly is key to bucking trees safely. Before you begin, make sure your chainsaw is in good working order and that you've read the manufacturer's instructions. The saw should be sharp and fueled up. Always keep the chainsaw blade tight and use the right chain oil. When cutting, use a firm grip and always hold the saw in both hands. Avoid cutting above shoulder height or in awkward positions, as this may increase your risk of injury. Lastly, never attempt to use your chainsaw one-handed – this is a recipe for disaster.
Bucking trees with a chainsaw can be a satisfying and efficient way to get the job done – but only if you follow the necessary safety precautions. By wearing protective gear, checking your surroundings, and using your chainsaw correctly, you'll be able to buck trees with confidence and peace of mind. Remember: safety always comes first!
Choosing the Right Chainsaw for Bucking Trees
Choosing the right chainsaw is crucial for efficient and effective bucking of trees. A chainsaw that is too small or underpowered for the job can make the task challenging and time-consuming, whereas a chainsaw that is too large can cause fatigue and even injury to the user. Here are some factors to consider when choosing the right chainsaw:
- Guide Bar Length: The guide bar length is the length of the cutting blade on a chainsaw. It is important to choose the right guide bar length depending on the size of the trees you plan to buck. Generally, for trees with a diameter of less than 12 inches, a guide bar length of 14-16 inches will suffice. For trees with a diameter of 12-20 inches, a guide bar length of 18-20 inches is recommended. For trees with a diameter of more than 20 inches, a guide bar length of 22-24 inches or more is required.
- Engine Power: Engine power is another crucial factor to consider when choosing a chainsaw for bucking trees. A chainsaw with a higher engine power will be more efficient in cutting through larger and harder trees. Generally, a chainsaw with an engine power of 30-50cc is sufficient for most residential tasks, whereas a chainsaw with an engine power of 60-100cc or more is required for commercial or professional use.
- Weight and Size: The weight and size of the chainsaw are also important factors to consider. A chainsaw that is too heavy or large can cause fatigue and strain on the user's arms and back, whereas a chainsaw that is too small or light may not be efficient in cutting through larger trees. It is essential to choose a chainsaw that is ergonomically designed and comfortable to handle.
- Safety Features: When choosing a chainsaw for bucking trees, safety features should also be considered. Look for chainsaws with features such as anti-vibration, automatic oiling system, and safety switches to prevent accidents and injuries.
By considering these factors, you can choose the right chainsaw for bucking trees and make the task easier, safer, and more efficient. Always remember to wear appropriate safety gear, including gloves, safety glasses, and ear protection, when operating a chainsaw.
Preparing the Tree for Bucking
Before you even start up your chainsaw, there are steps you must take to prepare the tree properly. Here’s what you need to do:
- Find the right location: The tree should be lying flat on the ground in a safe location where it won’t roll or move during the bucking process. Clear away any nearby debris that could get in the way.
- Remove any obstacles: Cut off any branches or limbs that could get in your way while you’re cutting the tree down. Check the area around the trunk to ensure there are no rocks or other obstacles that could cause problems.
- Consider the wind: Assess the direction and strength of the wind before starting your chainsaw. You should always cut with the wind at your back, so the tree falls away from you. If there is a strong wind, consider waiting for a calmer day.
- Make a plan: Decide on the cutting plan before you begin. Determine the number and size of the logs you want to create, and mark the cutting lines on the tree with chalk or spray paint.
- Think about safety: Wear the right safety gear, including sturdy work boots, eye protection, ear protection, and chainsaw chaps or other leg protection. Work with a partner, if possible, so you have someone to help watch for potential hazards and provide assistance if needed.
By taking the time to prepare the tree properly, you can make the bucking process safer and more efficient.
Techniques for Bucking Trees with a Chainsaw
Bucking a tree with a chainsaw can be a hazardous activity if not done correctly. It is vital to take necessary precautions and utilize proper techniques to get the job done safely and effectively. Here are some techniques that will help you buck a tree like a pro:
- Position the log appropriately: After felling the tree, decide which way you want the log to fall. If the log is already on the ground, make sure that it is lying straight and is not twisted or leaning against another object. Positioning the log properly will give you better access to make precise chainsaw cuts.
- Mark where to make the cuts: Use a chalk or spray paint to mark where you'll make your cuts. It is best to use the bar and chain to measure the length of the log and mark the cuts at regular intervals. This will ensure that the log is cut into uniform sections.
- Use the right chainsaw size: Choose a chainsaw that is the appropriate size for the job. A larger chainsaw will make it easier to cut through a larger log but will be challenging to maneuver around small branches and twigs.
- Use the correct chainsaw chain: Using a dull chainsaw chain can lead to accidents. Make sure to use a sharp chain that is suitable for bucking, which is designed to cut through larger logs easily.
- Start bucking the log: Begin cutting from the top of the log and work your way downwards. The top of the log is always the easiest to cut since gravity will be working with you. Use the bottom of the chainsaw bar to make the cut, since it is less likely to get lodged in the log.
- Make a back cut: The back cut is the final cut that will release the log. Make this cut at the opposite of the first cut but not all the way through. Leave a hinge of about 1-2 inches to guide the log's fall. Make sure to create a notch on the opposite side of the log to keep the chainsaw from binding during the back cut.
- Stay alert: Be aware of your surroundings. Stand on higher ground and keep the chainsaw at a safe distance from your feet. Be mindful of the log's position and make sure you're not underneath its weight as it falls.
Conclusion: Bucking a tree with a chainsaw can be a hazardous activity, but if done correctly, it can be done safely and effectively. Remember to take all necessary precautions and use the right techniques to avoid accidents and ensure the job's success. Use the right size and chain for your chainsaw, position the log correctly, and stay aware of your surroundings while making precise cuts. Hopefully, these tips will help make the task more manageable and efficient.
Tips for Efficient and Effective Bucking
After safely felling a tree with your chainsaw, the next step is to buck it into manageable pieces. This can be a physically demanding task that requires careful technique and attention to safety. Here are some tips to help you efficiently and effectively buck a tree:
- Plan your cuts: Before you start cutting, take a moment to plan out where you will make your cuts. This will help you avoid any hazards and ensure that the pieces are the right size for your needs. Consider the length and thickness of the logs or boards you need to create and plan your cuts accordingly.
- Secure the log: Once you've decided where to make your first cut, make sure the log is secure. You can use wedges, a sawbuck or a similar device to keep the log in place and prevent it from rolling or shifting while you cut.
- Start with a shallow cut: To prevent the chainsaw from binding, start with a shallow cut on the top side of the log or branch. This will help you create a hinge and guide the saw as you make deeper cuts.
- Use the right stance: When bucking a log, you should stand to the side of the saw, with your feet shoulder-width apart and your knees slightly bent. Keep your weight balanced and avoid leaning too much to one side or the other.
- Alternate your cuts: To prevent the saw from binding or overheating, alternate the side of the log or branch that you cut on. This will help distribute the weight and stress evenly and make it easier to complete the cut.
- Use a sharp chainsaw: A dull chainsaw will make the task of bucking more difficult and dangerous. Make sure your saw is sharp and in good condition before you begin.
- Wear the right gear: Bucking a tree can be hazardous work, so make sure you're wearing the right protective gear. This includes safety glasses, earplugs, a hard hat, gloves, and boots with good traction.
- Take breaks: Bucking can be physically demanding work, so it's important to take breaks and rest when you need to. This will help prevent fatigue and reduce the risk of injury.
By following these tips, you can buck a tree more efficiently and effectively, while reducing the risk of injury or damage to your chainsaw. Remember to always prioritize safety and take your time to ensure each cut is made with care.
Proper Maintenance and Care for Your Chainsaw after Bucking Trees
Clearing a fallen tree using a chainsaw can be an exhausting task. You have to ensure that it is done correctly and safely. However, it is not just about cutting the tree, you also have to take good care of your chainsaw after using it. Proper maintenance is essential to ensure that it continues to work efficiently.
Clean the Chainsaw
The chainsaw becomes covered with wood debris and sawdust after cutting. Make sure to clean the saw after each use. Use a soft-bristled brush or compressed air to clean it. Ensure you use a cleaning cloth to remove the dirt that has accumulated on the body and chain. Never use a pressure washer to clean it as it could damage the inner parts of the saw.
Sharpen the Chain
A blunt chainsaw chain is not only inefficient but also dangerous. Make sure to sharpen the chain after cutting a few trees. A sharp chain will reduce the time it takes to cut through wood and make the task easier. Follow the manufacturer's instructions to sharpen the chain and make sure the cutting edge is uniformly sharp. You can also consider taking it to a professional to sharpen the chain.
Change the air filter and spark plug
The air filter and spark plugs can become clogged up with sawdust and dirt after cutting trees. It can affect the chainsaw's performance and efficiency. It is necessary to clean or replace the air filter and spark plug after each use. Make sure to follow the manufacturer's instructions to change the air filter and spark plug.
Check the chain tension
Check the chain tension before every use of the saw. A loose chain can cause accidents and damage the saw. Make sure to follow the manufacturer's instructions to tighten the chain and adjust the tension.
Inspect the saw for any damage
Make sure to inspect the chainsaw for damage after every use. Check the chain, chain brake, and sprocket for any wear and tear. Ensure to replace or repair any damaged parts before using it again.
Store it safely
Store the chainsaw in a dry and secure place. Keep it out of the reach of children and away from flammable materials. Cover it with a protective cover to prevent dust and debris from accumulating on the saw.
Caring and maintaining your chainsaw after bucking trees is essential to keep it working efficiently and safely. Proper maintenance will increase its lifespan and keep you safe while using it. Follow the manufacturer's instructions for maintenance and servicing and always wear protective clothing and equipment when using the chainsaw. | <urn:uuid:98ea19eb-f4df-45fd-a767-90c95e703df9> | CC-MAIN-2024-51 | https://www.botanikks.com/gardening/how-to-buck-a-tree-with-a-chainsaw/16291/1 | 2024-12-09T04:00:27Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066460657.93/warc/CC-MAIN-20241209024434-20241209054434-00700.warc.gz | en | 0.933071 | 2,911 | 2.71875 | 3 |
After water, concrete is the most widely used substance on
the planet. But its benefits mask enormous dangers to the planet, to human
health – and to culture itself
In the time it takes you to read this sentence, the
global building industry will have poured more than 19,000 bathtubs of
concrete. By the time you are halfway through this article, the volume would
fill the Albert Hall and spill out into Hyde Park. In a day it would be almost
the size of China’s Three Gorges Dam. In a single year, there is enough to
patio over every hill, dale, nook and cranny in England.
After water, concrete is the most widely used substance on
Earth. If the cement industry were a country, it would be the third largest
carbon dioxide emitter in the world with up to 2.8bn tonnes, surpassed only
by China and
The material is the foundation of modern development,
putting roofs over the heads of billions, fortifying our defences against
natural disaster and providing a structure for healthcare, education,
transport, energy and industry.
Concrete is how we try to tame nature. Our slabs protect us
from the elements. They keep the rain from our heads, the cold from our bones
and the mud from our feet. But they also entomb vast tracts of fertile soil,
constipate rivers, choke habitats and – acting as a rock-hard second skin –
desensitise us from what is happening outside our urban fortresses.
Our blue and green world is becoming greyer by the second.
calculation, we may have already passed the point where concrete outweighs
the combined carbon mass of every tree, bush and shrub on the planet. Our built
environment is, in these terms, outgrowing the natural one. Unlike the natural
world, however, it does not actually grow. Instead, its chief quality is to
harden and then degrade, extremely slowly.
All the plastic produced over the past 60 years amounts to
8bn tonnes. The cement industry pumps out more than that every two years. But
though the problem is bigger than plastic, it is generally seen as less severe.
Concrete is not derived from fossil fuels. It is not being found in the
stomachs of whales and seagulls. Doctors aren’t discovering traces of it in our
blood. Nor do we see it tangled in oak trees or contributing to subterranean
fatbergs. We know where we are with concrete. Or to be more precise, we know
where it is going: nowhere. Which is exactly why we have come to rely on it.
This solidity, of course, is what humankind yearns for.
Concrete is beloved for its weight and endurance. That is why it serves as the
foundation of modern life, holding time, nature, the elements and entropy at
bay. When combined with steel, it is the material that ensures our dams don’t
burst, our tower blocks don’t fall, our roads don’t buckle and our electricity
grid remains connected.
Solidity is a particularly attractive quality at a time of
disorientating change. But – like any good thing in excess – it can create more
problems than it solves.
At times an unyielding ally, at times a false friend,
concrete can resist nature for decades and then suddenly amplify its impact.
Take the floods in New Orleans after Hurricane Katrina and Houston after
Harvey, which were more severe because urban and suburban streets could not
soak up the rain like a floodplain, and storm drains proved woefully
inadequate for the new extremes of a disrupted climate.

canal, New Orleans, after it was breached during Hurricane Katrina. Photograph:
It also magnifies the extreme weather it shelters us from.
Taking in all stages of production, concrete is said to be responsible
for 4-8% of
the world’s CO2. Among materials, only coal, oil and gas are a greater source
of greenhouse gases. Half of concrete’s CO2 emissions are created during the
manufacture of clinker, the most-energy intensive part of the cement-making
But other environmental impacts are far less well
understood. Concrete is a thirsty behemoth, sucking up almost a 10th of the
world’s industrial water use. This often strains supplies for drinking and
irrigation, because 75% of this
consumption is in drought and water-stressed regions. In cities, concrete
also adds to the heat-island effect by absorbing the warmth of the sun and
trapping gases from car exhausts and air-conditioner units – though it is, at
least, better than darker asphalt.
It also worsens the problem of silicosis and other
respiratory diseases. The dust from wind-blown stocks and mixers contributes as
much as 10% of the coarse particulate matter that chokes Delhi, where
in 2015 that the air pollution index at all of the 19 biggest
construction sites exceeded safe levels by at least three times. Limestone
quarries and cement factories are also often pollution sources, along with the
trucks that ferry materials between them and building sites. At this scale,
even the acquisition of sand can be catastrophic – destroying
so many of the world’s beaches and river courses that this form of
mining is now increasingly
run by organised crime gangs and associated with murderous
This touches on the most severe, but least understood,
impact of concrete, which is that it destroys natural infrastructure without
replacing the ecological functions that humanity depends on for fertilisation,
pollination, flood control, oxygen production and water purification.
Concrete can take our civilisation upwards, up to 163
storeys high in the case of the Burj Khalifa skyscraper in Dubai, creating
living space out of the air. But it also pushes the human footprint outwards,
sprawling across fertile topsoil and choking habitats. The biodiversity crisis
– which many scientists believe to be as
much of a threat as climate chaos – is driven primarily by the
conversion of wilderness to agriculture, industrial estates and residential
For hundreds of years, humanity has been willing to accept
this environmental downside in return for the undoubted benefits of concrete.
But the balance may now be tilting in the other direction.
The Pantheon and Colosseum in Rome are testament to
the durability of concrete, which is a composite of sand, aggregate (usually
gravel or stones) and water mixed with a lime-based, kiln-baked binder. The
modern industrialised form of the binder – Portland cement – was patented as a
form of “artificial stone” in 1824 by Joseph Aspdin in Leeds. This was later
combined with steel rods or mesh to create reinforced concrete, the basis for
art deco skyscrapers such as the Empire State Building.
Rivers of it were poured after the second world war, when
concrete offered an inexpensive and simple way to rebuild cities devastated by
bombing. This was the period of brutalist architects such
as Le Corbusier, followed by the futuristic, free-flowing
curves of Oscar Niemeyer and the elegant lines of Tadao
Ando – not to mention an ever-growing legion of dams, bridges, ports,
city halls, university campuses, shopping centres and uniformly grim car parks.
In 1950, cement production was equal to that of steel; in the years since, it
has increased 25-fold, more than three times as fast as its metallic
Debate about the aesthetics has tended to polarise between
traditionalists like Prince Charles, who condemned Owen Luder’s brutalist
Tricorn Centre as a “mildewed lump of elephant droppings”, and modernists who
saw concrete as a means of making style, size and strength affordable for the
The politics of concrete are less divisive, but more
corrosive. The main problem here is inertia. Once this material binds
politicians, bureaucrats and construction companies, the resulting nexus is
almost impossible to budge. Party leaders need the donations and kickbacks from
building firms to get elected, state planners need more projects to maintain
economic growth, and construction bosses need more contracts to keep money
rolling in, staff employed and political influence high. Hence the
self-perpetuating political enthusiasm for environmentally and socially dubious
infrastructure projects and cement-fests like the Olympics, the World Cup and
The classic example is Japan, which embraced
concrete in the second half of the 20th century with such enthusiasm that the
country’s governance structure was often described as the doken kokka (construction

At first it was a cheap material to rebuild cities ravaged
by fire bombs and nuclear warheads in the second world war. Then it provided
the foundations for a new model of super-rapid economic development: new
railway tracks for Shinkansen bullet trains, new bridges and tunnels for
elevated expressways, new runways for airports, new stadiums for the 1964
Olympics and the Osaka Expo, and new city halls, schools and sports facilities.
This kept the economy racing along at near double-digit
growth rates until the late 1980s, ensuring employment remained high and giving
the ruling Liberal Democratic party a stranglehold on power. The political
heavyweights of the era – men such as Kakuei Tanaka, Yasuhiro Nakasone and
Noboru Takeshita – were judged by their ability to bring hefty projects to
their hometowns. Huge kickbacks were the norm. Yakuza gangsters, who served as
go-betweens and enforcers, also got their cut. Bid-rigging and near monopolies
by the big six building firms (Shimizu, Taisei, Kajima, Takenaka, Obayashi,
Kumagai) ensured contracts were lucrative enough to provide hefty kickbacks to
the politicians. The doken kokka was a racket on a
But there is only so much concrete you can usefully lay
without ruining the environment. The ever-diminishing returns were made
apparent in the 1990s, when even the most creative politicians struggled to
justify the government’s stimulus spending packages. This was a period of extraordinarily
expensive bridges to sparsely inhabited regions, multi-lane roads
between tiny rural communities, cementing over the few remaining natural
riverbanks, and pouring ever greater volumes of concrete into the sea walls
that were supposed to protect 40% of the Japanese coastline.
In his book Dogs and Demons, the author and longtime
Japanese resident Alex Kerr laments the cementing over of riverbanks and
hillsides in the name of flood and mudslide prevention. Runaway
government-subsidised construction projects, he told an interviewer,
“have wreaked untold damage on mountains, rivers, streams, lakes, wetlands,
everywhere — and it goes on at a heightened pace. That is the reality of modern
Japan, and the numbers are staggering.”
He said the amount of concrete laid per square metre in
Japan is 30 times the amount in America, and that the volume is almost exactly
the same. “So we’re talking about a country the size of California laying the
same amount of concrete [as the entire US]. Multiply America’s strip malls and
urban sprawl by 30 to get a sense of what’s going on in Japan.”
Traditionalists and environmentalists were horrified – and
ignored. The cementation of Japan ran contrary to classic aesthetic ideals of
harmony with nature and an appreciation of mujo (impermanence),
but was understandable given the ever-present fear of earthquakes and tsunamis
in one of the world’s most seismically active nations. Everyone knew the grey
banked rivers and shorelines were ugly, but nobody cared as long as they could
keep their homes from being flooded.
Which made the devastating 2011
Tohoku earthquake and
tsunami all the more shocking. At coastal towns such as Ishinomaki,
Kamaishi and Kitakami, huge sea walls that had been built over decades were
swamped in minutes. Almost 16,000 people died, a million buildings were
destroyed or damaged, town streets were blocked with beached ships and port
waters were filled with floating cars. It was a still more alarming story at
Fukushima, where the ocean surge engulfed the outer defences of the Fukushima
plant and caused a level 7 meltdown.
Briefly, it seemed this might become a King Canute moment
for Japan – when the folly of human hubris was exposed by the power of nature.
But the concrete lobby was just too strong. The Liberal Democratic party
returned to power a year later with a promise to spend 200tn yen (£1.4tn) on
public works over the next decade, equivalent to about 40% of Japan’s economic

Construction firms were once again ordered to hold back the
sea, this time with even taller, thicker barriers. Their value is contested.
Engineers claim these 12-metre-high walls of concrete will stop or at least
slow future tsunamis, but locals have heard such promises before. The area
these defences protect is also of lower human worth now the land has been
largely depopulated and filled with paddy fields and fish farms.
Environmentalists say mangrove forests could provide a far cheaper buffer.
Tellingly, even many tsunami-scarred locals hate the concrete between them and
“It feels like we’re in jail, even though we haven’t done anything bad,” an oyster fisherman, Atsushi Fujita, told Reuters. “We can no longer see the sea,” said the Tokyo-born photographer Tadashi Ono, who took some of the most powerful images of these massive new structures. He described them as an abandonment of Japanese history and culture. “Our richness as a civilisation is because of our contact with the ocean,” he said. “Japan has always lived with the sea, and we were protected by the sea. And now the Japanese government has decided to shut out the sea.”https://www.theguardian.com/cities/2019/feb/25/concrete-the-most-destructive-material-on-earth

NCERT Solutions for Class 12 Biology Chapter 2 Sexual Reproduction in Flowering Plants
These Solutions are part of NCERT Solutions for Class 12 Biology. Here we have given NCERT Solutions for Class 12 Biology Chapter 2 Sexual Reproduction in Flowering Plants
Name the parts of an angiosperm flower in which development of male and female gametophyte take place.
Inside the anther, the cells of microsporangia develop as male gamete. Inside the ovary megasporangial cells develop as female gametes.
Differentiate between microsporogenesis and megasporogenesis. Which type of cell division occurs during these events? Name the structures formed at the end of these two events.
Differences between microsporogenesis and megasporogenesis are as follows :
During microsporogenesis and Megas-megasporogenesis meiotic cell division occurs which results in haploid gametes – the microspores or pollen grains and megaspores.
Arrange the following terms in- the correct developmental sequence : Pollen grain, sporogenous tissue, microspore tetrad, pollen mother cell, male gametes.
Sporogenous tissue → Pollen mother cell → microspore tetrad → pollen grain → male gamete.
With a neat, labelled diagram, describe the parts of a typical angiosperm ovule.
An angiosperm ovule consists of the following parts:
- The ovule is attached to placenta by means of a stalk called funicle or funiculus.
- The point of attachment of funiculus to the body of ovule is called hilum.
- The main body of ovule is made of parenchymatous tissue called nucellus.
- Nucellus is covered on its outside by one or two coverings called integuments and hence ovule is rightly called as integument megasporangium.
- The integuments cover entire nucellus except for a small pore at upper end, which is called the micropyle. Micropyle is formed generally by inner integument or by both integuments.
- The place of junction of integuments and nucellus is called chalaza.
- In inverted ovules (most common type), the stalk or funiculus is attached to the main body of ovule for some distance to form a ridge like structure, called- raphe.
- In the nucellus of ovule, a large oval cell is present at micropylar end, which is known as embryo sac (female gametophyte), which develops from the megaspore.
What is meant by monosporic development of female gametophyte?
The female gametophyte or the embryo sac develops, from a single functional megaspore. This is known as the monosporic development of the female gametophyte. In most flowering plants, a single megaspore mother cell present at the micropylar pole of the nucellus region of the ovule undergoes meiosis to produce four haploid megaspores. Later out of these 4 megaspores, only one functional megaspore develops into a female gametophyte, while the remaining 3 degenerates.
With a neat diagram explain the 7-celled, 8 nucleate nature of the female gametophyte
The female gametophyte (embryo sac) develops from a single functional megaspore. Thus, the megaspore undergoes three successive mitotic divisions to form 8 nucleate embryo sac. The first mitotic division in the megaspore forms 2 nuclei. One nucleus moves towards the micropylar end while the other nucleus moves towards the chalazal end. Then these nuclei divide at their respective ends and redivide to form 8 nucleate stages.
As a result there are 4 nuclei each at both the ends i.e., at the micropylar and the chalazal end in the embryo sac. At the micropylar end, out of 4 nuclei only 3 differentiate into 2 synergids and one egg cell. Together they are known as egg apparatus. Similarly, at the chalazal end 3 out of 4 nuclei differentiates as antipodal cells. The remaining 2 cells (of the micropylar and chalazal end) move towards the centre and are known as the polar nuclei, which are situated in the centre of the embryo sac. Hence, at maturity, the female gametophyte appears as a 7 celled structure, though it has 8 nucleate.
What are chasmogamous flowers? Can cross-pollination occur in cleistogamous flowers? Give reasons for your answer.
Chasmogamous flowers or open flowers in which anther and stigma are exposed for pollination. Cross-pollination cannot occur in cleistogamous flowers. These flowers remain closed thus causing only self-pollination. In cleistogamous flowers, anthers dehisce inside the closed flowers. So the pollen grains come in contact with stigma. Thus there is no chance of cross¬pollination, e.g., Oxalis, Viola.
Mention two strategies evolved to prevent self pollination in flowers.
Two strategies evolved to prevent self-pollination are:
- Pollen release and stigma receptivity are not synchronized.
- Anthers and stigma are placed at such positions that pollen doesn’t reach stigma.
What is self-incompatibility? Why does self-pollination not lead to seed formation in self-incompatible species?
When the pollen grains of an anther do not germinate on the stigma of the same flower, then such a flower is called self-sterile or incompatible and such condition is known as self¬incompatibility or self-sterility.
The transference of pollen grains shed from the anther to the stigma of the pistil is called pollination. This transference initiate the process of seed formation. Self-pollination is the transfer of pollen grain shed from the anther to stigma of pistil in the same flower. But in some flower self¬pollination does not lead to the formation of seed formation because of the presence of same sterile gene on pistil and pollen grain.
What is bagging technique? How is it useful in a plant breeding programme?
It is the covering of female plants with butter paper or polythene to avoid their contamination from foreign pollens during the breeding programme.
What is triple fusion? Where and how does it take place? Name the nuclei involved in triple fusion.
Inside the embryo sac, one male gamete fuses with egg cells to form a zygote (2n) and this is called syngamy or true act of fertilisation. This result of syngamy, i.e., zygote (2n) ultimately develops into an embryo.
The second male gamete fuses with 2 polar nuclei or secondary nucleus to form triploid primary endosperm nucleus and this is called triple fusion. The result of triple fusion, i.e., primary endosperm nucleus (3n) ultimately develops into a nutritive tissue for developing embryo called endosperm.
The nuclei involved in this triple fusion are the two polar nuclei or secondary nucleus and the second male gamete.
Why do you think the zygote is dormant for sometime in a fertilised ovule?
The zygote is dormant in fertilized ovule for some time because, at this time, endosperm needs to develop. As endosperm is the source of nutrition for the developing embryo, nature ensures the formation of enough endosperm tissue before starting the process of embryogenesis.
- Epicotyl and hypocotyl;
- Coleoptile and coleorhiza;
- Integument and testa;
- Perisperm and pericarp
- Differences between epicotyl and hypocotyl are as follows :
- Differences between coleoptile and coleorhiza are as follows :
- Differences between integument and testa are as follows :
- Differences between perisperm and pericarp are as follows :
Why is apple called a false fruit? Which part (s) of the flower forms the fruit?
Apple is called a false fruit because it develops from the thalamus instead of the ovary (the thalamus is the enlarged structure at the base of the flower).
What is meant by emasculation? When and why does a plant breeder employ this technique?
Emasculation is the removal of stamens mainly the anthers from the flower buds before their dehiscence. This is mainly done to avoid self-pollination. Emasculation is one of the measures in the artificial hybridization. Plant breeders employed this technique to prevent the pollination within same flower or to pollinate stigmas with pollens of desired variety.
If one can induce parthenocarpy through the application of growth substances, which fruits would you select to induce parthenocarpy and why ?
Oranges, lemons, litchis could be potential fruits for inducing the parthenocarpy because a seedless variety of these fruits would be much appreciated by the consumers.
Explain the role of tapetum in the formation of pollen-grain wall.
Tapetum is the innermost layer of the microsporangium. The tapetal cells are multinucleated and polyploid. They nourish the developing pollen grains. These cells contain ubisch bodies that help in the ornamentation of the microspores or pollen grains walls. The outer layer of the pollen grain is called exine and is made up of the sporopollenin secreted by the ubisch bodies of the tapetal cells. This compound provides spiny appearance to the exine of the pollen grains.
What is apomixis and what is its importance ?
Apomixis is the process of asexual production of seeds, without fertilization.
The plants that grow from these seeds are identical to the mother plant.
- It is a cost-effective method for producing seeds.
- It has great use for plant breeding when specific traits of a plant have to be preserved.

The UK Parliament makes up the legislative branch of the UK government. It is composed of two separate bodies; the House of Commons and the House of Lords, which makes it a bicameral parliament as it has two 'chambers'. The House of Commons comprises representatives who the people elect throughout the UK. In contrast, the House of Lords members are not elected. They both debate and amend news law and bounce off of one another until a decision is made. Each house represents parliament in different committees and councils throughout the legislature.
UK Parliament: House of Commons
The House of Commons is one of the two chambers of parliament. It is also known as the upper house. The members are elected through a public vote in general elections. Their main role is to debate and scrutinise proposed legislation and bring forth their own bills.
There are six hundred and fifty seats within the House of Commons. Most Members of Parliament (MPs) have been elected and gained a seat representing a political party, though some may run independently. MPs also represent their constituency alongside their political party. There are 650 constituencies within the UK parliament, and each MP represents a single constituency.
UK Parliament: House of Lords
The House of Lords is the second chamber within parliament, also known as the upper house. Alongside the House of Commons, they vote and debate upon proposed legislation. Scrutinising it and proposing changes where necessary. There is not a set number of seats, but in 2022, there were seven hundred and sixty-seven members within the House of Lords.
However, unlike the House of Commons, the House of Lords are not publicly elected. Most are nominated by those who have worked within the political and legal system throughout their lives, known as life peers.
Some members of the House of Lords hold their seats as hereditary peers – meaning that they inherit the position through their family. There are around 700 hereditary peers, but only 92 are entitled to a seat. The rest vote for who will sit in the House of Lords. The third type of seat held within the House of Lords is the Lords Spiritual, 26 of which the bishops of the UK hold.
UK Parliament's functions
The UK's parliament has three primary functions, passing legislation, parliamentary scrutiny, and providing ministers. Arguably the most important of these functions is to pass legislation. To do this, all proposed legislation must be deeply evaluated so that laws are fair. As such, parliament must debate and adjust them before they become legislation. The process in which this is done is known as the billing process.
Billing Process for a UK Act of Parliament
To pass an Act of Parliament in the UK a proposed bill needs to go through the billing process in both the House of Commons and the House of Lords. While most bills begin in the House of Commons, they can start in either house. For both Houses the process is the same:
Second Reading: debate the bill, but no amendments are made
Committee Stage: amendments are made to the bill
Report Stage: changes are reported back to the relevant House
Third Reading: final debates and changes are made
Once approved by the House of Commons, the bill moves to the House of Lords (or vice versa) to undergo the billing process. If changes are made to the bill, it will go through the process again. If the houses don’t agree on the changes made, it will move back and forth between the House of Commons and the House of Lords until they agree.
Finally, once the houses have agreed, the bill gets passed to the Crown to receive 'royal assent'. This is the final stage in the billing process, where the monarch signs the bill so that it becomes law.
Process of the passage of a bill, Wikimedia Commons
The Crown is the name given to the monarch who rules the UK. One of their duties is to seal bills, making them proper law. This is called getting Royal Assent.
Other parliamentary functions
Parliament is also there to hold the executive branch of the government to account. Making sure that they adhere to the constitution and don't abuse their power. Parliament is, therefore, part of a process known as parliamentary scrutiny. They do this in three primary ways. Firstly, through select committees which relate to governmental departments. Another way they do this is by posing questions to individual ministers on the matter, requesting either an oral or written response (e.g. a weekly Q&A in the House of Commons through the prime minister's questions). The final way is through a debate within the House of Lords or the House of Commons.
Another function of parliament is to provide ministers to represent and sit in cabinet as part of the executive branch of the government. To be a minister you must hold a seat in one of the Houses of Parliament. Lastly, the representation of the people is also a function of the UK parliament, though this only happens through the House of Commons, as this is the elected chamber of parliament.
Parliamentary scrutiny is one of the functions of the UK Parliament, whereby it scrutinises the policies and actions of the executive to ensure they are held to a high standard.
Members of the UK Parliament
People of the UK elect the Members of Parliament, or MPs, to the House of Commons in general elections. The public votes for the candidate they wish to represent their area within this process. These nominees usually represent a particular political party, such as the Conservatives or the Labour Party. How many constituencies a party wins determines how many seats they gain in the House of Commons. Therefore, every MP will represent their constituencies and their political party and will therefore often raise issues in the House of Commons relevant to their own constituency.
Petitioning Parliament in the UK
In the UK, one of the civil rights is that every individual is allowed to petition their parliament on matters of concern. If a petition gets enough signatures, it may persuade parliament to debate specific issues. Petitioning is a great way for parliament to understand and be made aware of the public's concerns. The ability to petition parliament is how the public can directly affect parliament.
There is a UK Parliament petitions website which organises petitions in the UK. If a petition reaches 10,000 signatures, then the government must respond. If it reaches 100,000 signatures, then there is usually a debate in parliament. The Petitions Committee in the House of Commons is responsible for organising this.
Over 600,000 people signed one recent petition that was debated in parliament. This petition was asking for the provision of a government ID to be required before opening a social media account. The petition was ignored by parliament as it would be too difficult to implement this law on all social media platforms.
A successful example is a petition in 2015 which argued that the government needed to accept more refugees and give greater support to refugees. This petition received over 450,000 signatures. After this, the government admitted 20,000 more Syrian refugees under the Syrian Vulnerable Persons Relocation scheme and spent an additional £100m in humanitarian aid.
Devolution in UK Parliament
Devolution is an important feature of the parliamentary system of the UK.
Devolution is the sharing of powers, which can be legislative, executive, and judicial powers, to lower levels such as local or regional governments.
It is a particularly important feature for the UK as parliament, the executive and the judiciary share devolved powers with Scotland, Wales, Northern Ireland, and England. These powers are usually over more local matters such as education and the environment but differ depending on who the powers are devolved to.
Even though the parliament has devolved some powers to these regional and local governments, there are some powers that only the UK parliament has; these are called reserved powers. They include matters of criminal law, human rights, international and national trading laws, laws that concern the NHS, and powers over detention.
There are several reasons that parliament has devolved some of their powers to these regional and local governments. Firstly, there is often greater local knowledge at the regional and local levels, meaning these areas can be governed more effectively than by the central government.
Another reason that parliament shared devolved powers is that some of these areas, especially Scotland, Wales and Northern Ireland, wanted more control over their nations. For Scotland and Wales, there were successful referendums in 1997 to ask the people if they wanted devolved powers. However, Northern Ireland gained its devolved powers through the Belfast Agreement 1998, also known as the Good Friday Agreement 1998, which helped end the conflict between Ireland and the UK. Therefore, giving devolved powers to these nations within the UK was due to their desires for autonomy and independence from the central government.
The last reason that parliament shared devolved powers was to lessen the strain on the system, especially for the devolution of parliamentary powers within England.
Some people have criticised the devolution of parliamentary powers by saying that it weakened parliamentary sovereignty, which is an important principle in the UK. Though others say that even though it does reduce the power of parliament because they still hold reserved powers, they are still sovereign.
Parliamentary sovereignty is the idea that parliament is sovereign; that is, parliament is the country's highest legal authority.
Another criticism of parliamentary devolution in the UK is that giving regional governments increased independence and autonomy, especially Northern Ireland, Scotland, and Wales, will give them a taste of freedom and leave them wanting more. Though others argue the opposite, that giving them this extra independence will satisfy them
Devolution is the passing of powers to regional or local levels within a state.
Parliament - Key takeaways
- The UK Parliament makes up the legislative branch of the government and consists of two separate bodies, the House of Commons and the House of Lords.
- The main functions of parliament are to pass Acts of Parliament, to perform parliamentary scrutiny, and to provide ministers for the executive.
- The people elect the House of Commons’ members, whereas the House of Lords' are not.
- MPs sit in the House of Commons and can therefore sit on the cabinet and various committees, representing their political parties and constituencies.
- Petitioning parliament is a great way for the public to make parliament debate and decide on issues that the public is concerned about.
- Devolution has spread out the powers of parliament to other authorities (and parliaments) within the UK, although the central parliament still holds reserved powers. | <urn:uuid:ce00d3f7-a8ae-444a-ba31-f71e3f64c08e> | CC-MAIN-2024-51 | https://www.studysmarter.co.uk/explanations/politics/uk-government/uk-parliament/ | 2024-12-09T05:01:33Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066460657.93/warc/CC-MAIN-20241209024434-20241209054434-00700.warc.gz | en | 0.968713 | 2,123 | 4.21875 | 4 |
Philipp Franz Balthasar von Siebold was a German physician, botanist and traveler. He achieved prominence by his studies of Japanese flora and fauna and the introduction of Western medicine in Japan. He was the father of the first female Japanese doctor educated in Western medicine, Kusumoto Ine.
Born into a family of doctors and professors of medicine in Würzburg (then in the Bishopric of Würzburg, later part of Bavaria), Siebold initially studied medicine at the University of Würzburg from November 1815, where he became a member of the Corps Moenania Würzburg. One of his professors was Franz Xaver Heller (1775–1840), author of the Flora Wirceburgensis ("Flora of the Grand Duchy of Würzburg", 1810–1811). Ignaz Döllinger (1770–1841), his professor of anatomy and physiology, however, most influenced him. Döllinger was one of the first professors to understand and treat medicine as a natural science. Siebold stayed with Döllinger, where he came in regular contact with other scientists. He read the books of Humboldt, a famous naturalist and explorer, which probably raised his desire to travel to distant lands. Philipp Franz von Siebold became a physician by earning his M.D. degree in 1820. He initially practiced medicine in Heidingsfeld, in the Kingdom of Bavaria, now part of Würzburg.
Invited to Holland by an acquaintance of his family, Siebold applied for a position as a military physician, which would enable him to travel to the Dutch colonies. He entered the Dutch military service on 19 June 1822, and was appointed as ship's surgeon on the frigate Adriana, sailing from Rotterdam to Batavia (present-day Jakarta) in the Dutch East Indies (now called Indonesia). On his trip to Batavia on the frigate Adriana, Siebold practiced his knowledge of the Dutch language and also rapidly learned Malay, and during the long voyage he began a collection of marine fauna. He arrived in Batavia on 18 February 1823.
As an army medical officer, Siebold was posted to an artillery unit. However, he was given a room for a few weeks at the residence of the Governor-General of the Dutch East Indies, Baron Godert van der Capellen, to recover from an illness. With his erudition, he impressed the Governor-General, and also the director of the botanical garden at Buitenzorg (now Bogor), Caspar Georg Carl Reinwardt. These men sensed in Siebold a worthy successor to Engelbert Kaempfer and Carl Peter Thunberg, two former resident physicians at Dejima, a Dutch trading post in Japan, the former of whom was the author of Flora Japonica. The Batavian Academy of Arts and Sciences soon elected Siebold as a member.
On 28 June 1823, after only a few months in the Dutch East Indies, Siebold was posted as resident physician and scientist to Dejima, a small artificial island and trading post at Nagasaki, and arrived there on 11 August 1823. During an eventful voyage to Japan he only just escaped drowning during a typhoon in the East China Sea. As only a very small number of Dutch personnel were allowed to live on this island, the posts of physician and scientist had to be combined. Dejima had been in the possession of the Dutch East India Company (known as the VOC) since the 17th century, but the Company had gone bankrupt in 1798, after which a trading post was operated there by the Dutch state for political considerations, with notable benefits to the Japanese.
The European tradition of sending doctors with botanical training to Japan was a long one. Sent on a mission by the Dutch East India Company, Engelbert Kaempfer (1651–1716), a German physician and botanist who lived in Japan from 1690 until 1692, ushered in this tradition of a combination of physician and botanist. The Dutch East India Company did not, however, actually employ the Swedish botanist and physician Carl Peter Thunberg (1743–1828), who had arrived in Japan in 1775.
Japanese scientists invited Siebold to show them the marvels of western science, and he learned in return through them much about the Japanese and their customs. After curing an influential local officer, Siebold gained the permission to leave the trade post. He used this opportunity to treat Japanese patients in the greater area around the trade post. Siebold is credited with the introduction of vaccination and pathological anatomy for the first time in Japan.
In 1824, Siebold started a medical school in Nagasaki, the Narutaki-juku, that grew into a meeting place for around fifty students. They helped him in his botanical and naturalistic studies. The Dutch language became the lingua franca (common spoken language) for these academic and scholarly contacts for a generation, until the Meiji Restoration.
His patients paid him in kind with a variety of objects and artifacts that would later gain historical significance. These everyday objects later became the basis of his large ethnographic collection, which consisted of everyday household goods, woodblock prints, tools and hand-crafted objects used by the Japanese people.
During his stay in Japan, Siebold "lived together" with Kusumoto Taki (楠本滝), who gave birth to their daughter Kusumoto (O-)Ine in 1827. Siebold used to call his wife "Otakusa" (probably derived from O-Taki-san) and named a Hydrangea after her. Kusumoto Ine eventually became the first Japanese woman known to have received a physician's training and became a highly regarded practicing physician and court physician to the Empress in 1882. She died at court in 1903.
His main interest, however, focused on the study of Japanese fauna and flora. He collected as much material as he could. Starting a small botanical garden behind his home (there was not much room on the small island) Siebold amassed over 1,000 native plants. In a specially built glasshouse he cultivated the Japanese plants to endure the Dutch climate. Local Japanese artists like Kawahara Keiga drew and painted images of these plants, creating botanical illustrations but also images of the daily life in Japan, which complemented his ethnographic collection. He hired Japanese hunters to track rare animals and collect specimens. Many specimens were collected with the help of his Japanese collaborators Keisuke Ito (1803–1901), Mizutani Sugeroku (1779–1833), Ōkochi Zonshin (1796–1882) and Katsuragawa Hoken (1797–1844), a physician to the shōgun. As well, Siebold's assistant and later successor, Heinrich Bürger (1806–1858), proved to be indispensable in carrying on Siebold's work in Japan.
Siebold first introduced to Europe such familiar garden-plants as the Hosta and the Hydrangea otaksa. Unknown to the Japanese, he was also able to smuggle out germinative seeds of tea plants to the botanical garden Buitenzorg in Batavia. Through this single act, he started the tea culture in Java, a Dutch colony at the time. Until then Japan had strictly guarded the trade in tea plants. Remarkably, in 1833, Java already could boast a half million tea plants.
He also introduced Japanese knotweed (Reynoutria japonica, syn. Fallopia japonica), which has become a highly invasive weed in Europe and North America. All derive from a single female plant collected by Siebold.
During his stay at Dejima, Siebold sent three shipments with an unknown number of herbarium specimens to Leiden, Ghent, Brussels and Antwerp. The shipment to Leiden contained the first specimens of the Japanese giant salamander (Andrias japonicus) to be sent to Europe.
In 1825 the government of the Dutch-Indies provided him with two assistants: apothecary and mineralogist Heinrich Bürger (his later successor) and the painter Carl Hubert de Villeneuve. Each would prove to be useful to Siebold's efforts that ranged from ethnographical to botanical to horticultural, when attempting to document the exotic Eastern Japanese experience. De Villeneuve taught Kawahara the techniques of Western painting.
Reportedly, Siebold was not the easiest man to deal with. He was in continuous conflict with his Dutch superiors who felt he was arrogant. This threat of conflict resulted in his recall in July 1827 back to Batavia. But the ship, the Cornelis Houtman, sent to carry him back to Batavia, was thrown ashore by a typhoon in Nagasaki bay. The same storm badly damaged Dejima and destroyed Siebold's botanical garden. Repaired, the Cornelis Houtman was refloated. It left for Batavia with 89 crates of Siebold's salvaged botanical collection, but Siebold himself remained behind in Dejima.
In 1826 Siebold made the court journey to Edo. During this long trip he collected many plants and animals. But he also obtained from the court astronomer Takahashi Kageyasu several detailed maps of Japan and Korea (written by Inō Tadataka), an act strictly forbidden by the Japanese government. When the Japanese discovered, by accident, that Siebold had a map of the northern parts of Japan, the government accused him of high treason and of being a spy for Russia.
The Japanese placed Siebold under house arrest and expelled him from Japan on 22 October 1829. Satisfied that his Japanese collaborators would continue his work, he journeyed back on the frigate Java to his former residence, Batavia, in possession of his enormous collection of thousands of animals and plants, his books and his maps. The botanical garden of Buitenzorg would soon house Siebold's surviving, living flora collection of 2,000 plants. He arrived in the Netherlands on 7 July 1830. His stay in Japan and Batavia had lasted for a period of eight years.
Philipp Franz von Siebold arrived in the Netherlands in 1830, just at a time when political troubles erupted in Brussels, leading soon to Belgian independence. Hastily he salvaged his ethnographic collections in Antwerp and his herbarium specimens in Brussels and took them to Leiden, helped by Johann Baptist Fischer. He left behind his botanical collections of living plants that were sent to the University of Ghent. The consequent expansion of this collection of rare and exotic plants led to the horticultural fame of Ghent. In gratitude the University of Ghent presented him in 1841 with specimens of every plant from his original collection.
Siebold settled in Leiden, taking with him the major part of his collection. The "Philipp Franz von Siebold collection", containing many type specimens, was the earliest botanical collection from Japan. Even today, it still remains a subject of ongoing research, a testimony to the depth of work undertaken by Siebold. It contained about 12,000 specimens, from which he could describe only about 2,300 species. The whole collection was purchased for a handsome amount by the Dutch government. Siebold was also granted a substantial annual allowance by the Dutch King William II and was appointed Advisor to the King for Japanese Affairs. In 1842, the King even raised Siebold to the nobility as an esquire.
The "Siebold collection" opened to the public in 1831. He founded a museum in his home in 1837. This small, private museum would eventually evolve into the National Museum of Ethnology in Leiden. Siebold's successor in Japan, Heinrich Bürger, sent Siebold three more shipments of herbarium specimens collected in Japan. This flora collection formed the basis of the Japanese collections of the National Herbarium of the Netherlands in Leiden, while the zoological specimens Siebold collected were kept by the Rijksmuseum van Natuurlijke Historie (National Museum of Natural History) in Leiden, which later became Naturalis. Both institutions merged into Naturalis Biodiversity Center in 2010, which now maintains the entire natural history collection that Siebold brought back to Leiden.
In 1845 Siebold married Helene von Gagern (1820–1877), they had three sons and two daughters. | <urn:uuid:38a8fccd-311e-42d5-88db-cbd5522ebc7d> | CC-MAIN-2024-51 | https://artvee.com/dl/fauna-japonica-pl-066/ | 2024-12-01T21:23:09Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066036672.6/warc/CC-MAIN-20241201192453-20241201222453-00100.warc.gz | en | 0.974635 | 2,621 | 2.8125 | 3 |

William Lane Craig, Herodotus, and Myth Formation (1999)
This essay addresses one specific argument made by William Lane Craig, to the effect that “tests” from Herodotus demonstrate that myths or legends (such as resurrection appearances or an empty tomb) cannot grow within a single generation. A great deal more could be said about myth formation than is covered here, but the aim right now is simpler: to show how Craig misrepresents one source and thus creates an empty argument out of whole cloth. I will preface the essay with a general point about the Gospels as history.
The Gospels as History
The context of the argument in question is a defense of the historicity of the resurrection, in two parts . The first part argues that “Paul’s information makes it certain that on separate occasions various individuals and groups saw Jesus alive from the dead” about which Craig says, “This conclusion is virtually indisputable.” I disagree, but I have argued that case elsewhere . In sum, the existence of appearances is not “indisputable,” since the influence of one man (Paul) on all the recorded traditions is embarrassingly great in comparison with almost any other “virtually indisputable” historical event. The possibility of invention by him is not easily refuted. Nevertheless, I do believe appearances of some sort occurred at least to one person, maybe others, but we have no access to accurate accounts of those events, and thus can say little with certainty about them. They could easily have been of a spiritual, hence subjective nature, and this is not good evidence (for us) of a real rise from the dead. Finally, what has survived has undergone transformations of a legendary sort, affected by dogmatic disputes within a growing church, by the need of leaders to assert authority, by credulity and piety among believers, through at least one if not two generations of oral history, including a major catastrophic event (the destruction of the original church, or at least the creed’s city of origin, by war in 70 A.D.), just to name the most prominent factors. But even if there were actual appearances, non-miraculous explanations remain for them which cannot be confidently falsified by the existing evidence. Given the lack of any modern support for the occurrence of miracles, we are left with no rationale for proposing miracles in antiquity when perfectly reasonable natural explanations are available .
But it is the second part of Craig’s argument that interests us here. It goes like this, “in order for these stories to be in the main legendary, a very considerable length of time must be available for the evolution and development of the traditions until the historical elements have been supplanted by unhistorical” [emphasis added]. To begin with, this argument does not lead to the conclusion Craig wants, for few if any real historians today think that the stories are “in the main” legendary, or that all the historical elements have been entirely replaced. Even if they did, refuting such a view does not demonstrate the historicity of any miraculous features of the accounts–since those are not “in the main” the contents of the Gospels, and they may not have supplanted so much as simply added to the historical core of the story.
The obstacle is not the lack of historical elements, but our inability to determine which elements are historical. We can surmise, for example that a man named Jesus preached a reform of Judaism in the time of Pontius Pilate the prefect of Judaea, which involved particular apocalyptic and ethical ideas and the gathering of disciples, that he travelled to certain places, was opposed by Jewish authorities and crucified by the Roman authorities on at least the pretext of leading a rebellion, etc. But we cannot be sure how much of even these details are historical, or to what degree–were there several such men, who were conflated and thought to be the same man? How much of the story is a revision or exaggeration created by those who shaped the church after him, such as Peter and Paul? Was Jesus really starting a rebellion, but when killed his followers changed the story to perfect a less direct means to the same end? How much is rumor created by believers and passed on? How much is dramatic invention? How much is purely the propaganda of Jesus himself or his advocates? Or rhetoric aimed at saving souls or securing authority among vying factions? Before the Gospels can be honestly discussed, one must be able to at least attempt an answer to these questions, and others like them, or else admit that they cannot be answered beyond the limits of human speculation, though the latter entails that the real history is all but lost in the details.
Yet Craig never even acknowledges such questions, or dismisses them outright. He makes it seem as if it is either all history or all legend. No actual historian thinks that way about any text . And yet if Craig acknowledges that at least some of the Gospel stories are legendary or otherwise distortions or inventions, then he must explain why the miraculous features are not to be included among them. His approach allows him to hide this problem by focussing on Paul, but Paul does not tell us anything about the Gospel stories apart from a concise statement of the creed itself, which is simplistic and vague and thus open to numerous interpretations (to which it was no doubt subject even in Paul’s day). That Paul “believed” there was an empty tomb or bodily appearances is never stated by him. It must be “interpreted” from the text. That alone places any such conclusions of shaky, subjective ground. Had we never had the Gospels we would not have any reason to suppose such details were in Paul’s mind when he wrote what he did. Thus, the Gospels must be the starting point for any such speculation–meaning that Craig must face the fact that either the Gospels contain some legends or they do not. The latter is absurd. The former sweeps away any claim to certainty about the appearances or the empty tomb, at least in respect to the details (e.g. who saw what when, what exactly was seen, etc.) if not the basic facts themselves.
Craig’s main defense of the “it cannot be myth” argument is based on a misrepresented reading of A.N. Sherwin-White . Craig’s argument is reproduced here in full to make sure I am not misrepresenting it myself:
Professor Sherwin-White is not a theologian; he is an eminent historian of Roman and Greek times, roughly contemporaneous with the NT. According to Professor Sherwin-White, the sources for Roman history are usually biased and removed at least one or two generations or even centuries from the events they record. Yet, he says, historians reconstruct with confidence what really happened. He chastises NT critics for not realizing what invaluable sources they have in the gospels. The writings of Herodotus furnish a test case for the rate of legendary accumulation, and the tests show that even two generations is too short a time span to allow legendary tendencies to wipe out the hard core of historical facts. When Professor Sherwin-White turns to the gospels, he states for these to be legends, the rate of legendary accumulation would have to be ‘unbelievable’; more generations are needed.
To someone unfamiliar with the text he is citing, it certainly seems as if Sherwin-White believes that no part of the Gospel stories is legendary, that for legends to appear in them is “unbelievable,” that “tests” (plural) have been performed on the text of Herodotus, and that these tests “show,” convincingly enough to use the argument at all, that legends require many generations to develop. We will see that Sherwin-White never argues any of these points, and thus Craig is not representing his source fairly or correctly. I find this to be either a dishonest or an incompetent use of a source that Craig should not be proud of.
The only saving qualification is that Craig says the tests prove that it is impossible for legends to wipe out some undefined hard core of historical facts. But even this entails a more subtle misrepresentation of Sherwin-White. This brings us back to the fault line in Craig’s argument noted before: that the appearances and empty tomb stories are the amplified and distorted record of some core historical facts does not entail that the hard core of fact was wiped out. The “hard core” of fact might be that the appearances were spiritual visions, and that there was a tomb but it’s emptiness was of a spiritual character–e.g., that which was Jesus is risen, the body being irrelevant. This is not even counting the possible natural causes for physical appearances or empty tombs which could then have been lost or overlain with legend. If there are any legends clouding the facts anywhere else in the Gospels, then the same problem could just as well exist here, and so Craig’s entire argument fails to establish the historicity of the stories as told. In other words, it follows that Craig must be implying that Sherwin-White agrees that the physical appearances and empty tomb are the very “hard core” of historical fact that cannot be legendary. Otherwise, there is no reason to cite him in this context–for if Sherwin-White’s actual argument does not entail this, then, whatever Sherwin-White demonstrated, it is irrelevant to the argument Craig is building. If that is the case, then Craig should not be referring to him at all, or at least he should honestly lay out the features of Sherwin-White’s argument that weaken or undermine Craig’s conclusions, and not present him as only being in agreement.
What Sherwin-White Actually Wrote
Consider what Sherwin-White says about Acts. “For Acts the confirmation of historicity is overwhelming. Yet Acts is, in simple terms and judged externally, no less of a propaganda narrative than the Gospels, liable to similar distortions” . In other words, there are genuine historical details in Acts, but it is clouded with “propaganda” and “distortions,” just as the Gospels are. This does not support Craig. It supports the belief that Acts and the Gospels contain untruths. Sherwin-White does not tell us which details are to be regarded as historical, but clearly he believes that legends and falsehoods can and do exist in these documents, and thus he does not believe that a few generations are “not enough” for such elements to appear. Why does Craig represent him as thinking otherwise? When we actually read all of Sherwin-White’s argument we discover that he merely objects to the notion that “the historical content is…hopelessly lost.” Thus, he is arguing against an extreme minority of scholars who reject the Gospels entirely. He is not arguing for the historicity of the empty tomb or the physical appearances of Jesus, and his arguments cannot be extended to include them .
Sherwin-White then turns to Herodotus for an analogy. Regarding accounts of the Persian Wars:
[They] are retold by Herodotus from forty to seventy years later, after they had been remodeled by at least one generation of oral transmission. The parallel with the authors of the Gospels is by no means so far-fetched as it might seem. Both regard their material with enthusiasm rather than detached criticism. Both are the first to produce a written narrative of great events which they regard as a mighty saga, national or ecclesiastical and esoterical as the case may be. For both their story is the vehicle of a moral or a religious idea which shapes the narrative….Yet the material of Herodotus….has not been transformed out of all recognition under the influence of moral and patriotic fervour
Note the details: Sherwin-White admits that even in Herodotus there has been “remodeling” and a lack of “detached criticism” (i.e. “a receptiveness to falsehood”) as well as a motivating bias to shape the stories toward an agenda, and that all we can say is that the result has not been mythologized out of all recognition. This is a substantially weaker conclusion than Craig represents it to be, as I have discussed already. When I examine below the actual stories in question, we will see plenty of legendary material being believed, or created, by Herodotus or his audience, thus demonstrating–if we accept the analogy, as both Sherwin-White and Craig apparently do–that the same thing certainly could have happened in the Gospels. I can only assume that Craig did not examine Herodotus himself, yet this exhibits that basic historical incompetence which characterizes Christian apologists, undermining confidence in their conclusions.
Indeed, even Sherwin-White goes too far, driven by his own agenda (to refute the extremists). He, like Craig, fails to note the crucial differences between the Gospel authors and Herodotus (not the least of which being the anonymity of the former). Yet in any argument from analogy, the differences are as crucial as the similarities and thus not to be left out. The Gospel authors are driven by a religious faith and an evangelical agenda lacking in Herodotus–though he has a moral to tell, for him any facts would do, and thus he was not bound to any particular events, nor did his sources have any unified agenda in that sense. Belief in his account will not grant him or anyone else eternal salvation from the pit of Hell. Also, Herodotus often gives various versions of each account, sometimes he examines them critically, and he outright admits that he does not vouch for the truth of anything he says, but is merely writing down what others have told him . We find none of this honesty and critical thinking in the nameless Gospel authors, making them even more prone to perpetuating legends than Herodotus.
Moreover, there is another detail Sherwin-White omits, and it is worth noting that his audience was the historical community (the book is a collection of his lectures on an advanced topic) who would already be expected to know this: Herodotus is not alone. We have other written sources confirming at least the basic details of the events of the Persian Wars, including, we should not forget, the actual physical remains of the war dead at Marathon, and inscriptions commemorating related battles–the most spectacular of which, a bronze three-headed serpent-column commemorating those killed at Plataea, was moved to the Hippodrome in Istanbul by Constantine the Great and is still there today. Aeschylus–unlike Herodotus an actual participant in the Persian wars–composed a tragedy about the events (Persian Women) only five years after the war’s end, and Thucydides refers to some details as well (1.74, 1.138, etc.), as do Aristophanes, Lysias, Isagoras, and several others, only a generation or less after Herodotus–some also we know but whose works are lost, e.g. Ion of Chios, and another who lived during the war and wrote on it even before Aeschylus: Phrynicus, who composed two related tragedies (Capture of Miletus–even Herodotus cites this work, cf. 6.21–and Phoenician Women) . Thus, not only do we have independent checks on Herodotus, something totally lacking in the Christian Gospel tradition, but we know he was not alone in recounting these events in writing (and thus even later historians would have had written sources we lack).
Ignoring these crucial differences, Sherwin-White contends that “Herodotus enables us to test the tempo of myth-making, and the tests suggest that even two generations are too short a span to allow the mythical tendency to prevail over the hard historic core of the oral tradition” (p. 190), the obvious origin of Craig’s characterization of his argument. As I’ve already noted, few doubt that Jesus and certain other characters, and cultural, geographic and other details of these texts, form a genuine “historical core” worth mining for data. This is generally not in question. What is in question is what mythical and other distortions have entered the account, and almost all historians agree that a great deal of this is present in the Gospels, something Sherwin-White does not dispute (though Craig would have us believe otherwise). Sherwin-White only disputes the notion that myth will destroy the historical core. But even Homer has not done that, for we know that many core details in the Iliad are historically correct, not the least of which being the Trojan war, which he has clouded greatly by myth, invention, and chronological confusion–yet facts are there, and historians recognize the value of Homer despite the extent of fiction in his works. This does nothing to restore historicity to the more unbelievable details of the Gospels, such as the resurrection, nor does it help us to test the reliability of details like the tomb burial for which we cannot be certain of the source.
Nevertheless, despite the irrelevance of his point to Craig’s argument, Sherwin-White’s analysis still shows a central fault in even his own comparison: his “tests” consist of nothing more than one single example, a legend that we already know was circulating in the time of Herodotus (Histories 6.120-3), yet Herodotus recounts the “truth” rather than the legend . But this is not proof against the rapid creation of a legend–for the legend was already there, as Sherwin-White concedes (p. 190), and the fact that Herodotus has to argue against it proves irrefutably that legends do rise within a generation. So this example is only proof of the relatively critical acumen of Herodotus, entirely lacking in the NT authors, or perhaps his lack of any relevant agenda in this particular case–or indeed, even an opposing agenda, to highlight another heroic agent, as Sherwin-White also notes (p. 191). This tells us nothing about the Gospels–the analogy is not even portable. And it does not prove that legends do not rise within a generation–it actually proves the opposite! It is curious how this single, poor, irrelevant example becomes a plural notion of scientific-sounding “tests” in Sherwin-White’s argument, a grand hyperbole that Craig buys hook, line, and sinker–it appears that he only read the one sentence from Sherwin-White, and didn’t actually check to see if the plural (or even the word “test”) was really warranted. He has thus fallen victim to his source’s own rhetoric.
It is also worth pointing out that this “example” is a story that happened in the very city in which Herodotus is writing, whereas we have no evidence that any of the Gospel authors composed their works while in Jerusalem. And, unlike Athens, a major and devastating war had destroyed many witnesses and a great deal of physical evidence by the time the Gospel authors composed their accounts. Sherwin-White is not unaware of this, and couches his conclusion more carefully than Craig implies, saying that “this 0 suggests that, however strong the myth-forming tendency, the falsification does not automatically and absolutely prevail,” emphasis mine, “even with a writer like Herodotus, who was naturally predisposed in favour of certain political myths, and whose ethical and literary interests were stronger than his critical faculty” (p. 191). In other words, all he claims to have proved is that facts are not entirely and automatically replaced by myth even in uncritical authors–although Herodotus is far more critical than the Gospel authors, who never even express a single word of doubt, in contrast to numerous instances of this in the Histories. But almost all historians agree that some facts can survive the crucible of distortion in any source–this does not solve the real question of which ones.
Finally, Craig’s adulteration and misrepresentation conceals the fact that Sherwin-White’s only objective in composing this argument was to defend everything that precedes in his book, namely his historical analysis of the trial of Christ. Thus, his concluding remarks are all about how one cannot dismiss the possible historical core of the facts of the trial. He says nothing about miracles or the resurrection, much less anything to do with his burial or appearances or the empty tomb. Sherwin-White is explicit about the point of his argument in his closing words, “The point of my argument is not to suggest the literal accuracy of ancient sources, secular or ecclesiastical, but to offset the extreme skepticism with which the New Testament narratives are treated in some quarters.” We would never know this qualifying feature of his argument from Craig’s presentation.
“Recent” Legendary Developments in Herodotus
Craig’s argument is that “there simply was insufficient time for significant accrual of legend by the time of the gospels’ composition. Thus, I find current criticism’s skepticism with regard to the appearance traditions in the gospels to be unwarranted.” But this conclusion is based solely on the badly mischaracterized and, in fact, quite irrelevant argument of A.N. Sherwin-White. When we look at Herodotus ourselves, we find that Craig does not have a leg to stand on. It is believed that Herodotus wrote his account between 450 and 420 BC, so we will examine the least believable accounts of events after 490, on the grounds that 40 to 70 years is roughly the gap that falls between the death of Jesus and the Gospels.
Consider the astonishing suicide of Cleomenes, King of Sparta (490 BC). Herodotus tells us without a hint of skepticism that he went “mad” (though his only “mad” behavior was warding off untrusted noblemen with a stick) and was for this locked in a pillory. Then he demanded his guard give him a knife, threatening him repeatedly until he did so, at which he slowly mutilated himself in detailed fashion from the feet upwards, eventually dicing his own belly before dying (6.75). As A.R. Burn observed, “It was officially said that he had intimidated his helot jailer into giving him a knife, and had so mangled himself. The story reeks of the dark mystery of what went on behind the austere, Doric facade of Sparta” . One imagines that Herodotus, born today, would probably repeat without a bit of doubt the report that a dissident in Russia really died by “falling down the stairs.”
Then consider the lengthy speeches of Persian courtiers and their debate with Xerxes about making war on Greece (c. 486 BC), which span ten pages of printed English (7.5-18). It is patently impossible for Herodotus to have any sources for any of these speeches, not even their gist, much less their details–yet the content is cleverly constructed to convey Greek tragic and moral thinking. This is clearly his own “plausible invention” of what sort of debate might have happened, colored by his own moral agenda, but we are not told this–he presents it as if it is a factual story, pure narrative, just as we are given the conversations of Jewish councils and leaders in the Gospels. More astonishing is Herodotus’ record, shortly thereafter, of a horse giving birth to a rabbit (7.57). Then there is a fulfilled prophecy from the God Apollo: the priestess at Delphi accurately foretold the abandonment and burning of Athens, and a decisive naval victory at Salamis (7.140-143). This is clearly a prophecy invented after the fact to fit the actual, and unexpected, course of events, and thus a legendary development within a span of only 40 or so years, which Herodotus repeats as fact .
In 480-479 BC we have the account of the second Persian War, with several legends attending–and these were developed within less than forty years, and within the lifetime of Herodotus himself, even in his own city. There is the example of a legend being believed for patriotic reasons: Herodotus, being unbiased, gives both accounts (of the Argives and their political enemies), but the Argives clearly developed, in a very short time, a more face-saving myth explaining their inaction in the war (7.148-152). A similar face-saving myth is reported, with only mild skepticism, at 7.167. There was a popular legend in Herodotus’ day that Apollo bade them to summon the North Wind in a naval battle, and that it came upon their bidding, a story which Herodotus shies from outright challenging (7.189), then the Persian Magi cast a spell to make it stop on the fourth day, and it did (7.191-192). Similar legendary motifs attend descriptions of the battles and other events of the war: Xerxes “leaped thrice from his throne in fear of his army” (7.212); Scyllias deserted to the Greeks by swimming ten miles under water (8.8–Herodotus doubts it, but the story is still proof that many believed it); the temple of Delphi magically defended itself with animated armaments, lightning bolts, and collapsing cliffs (8.37-38); the sacred snake on the Acropolis would not eat its honeycake, confirming that the Athenians should desert the city (8.41); the sacred olive tree which had been burned up by the Persians grew a new shoot an arm’s length in a single day (8.55); a disembodied chant was heard in the holy city of Eleusis, then a dust cloud spontaneously arose from there and drifted toward Greece signaling that they would win the war, in accord with the prophecy of Dikaeus (8.65); a charming but possibly invented account of Artemisia’s incredible good luck in a naval battle (8.88–the punchline gives the story away as a possible myth); a story about Xerxes on his retreat that Herodotus doubts, but was clearly believed by others (8.118-120); a miraculous flood tide wiped out a Persian contingent that had desecrated an image of Poseidon (8.129); a morality tale about Persian decadence vs. Greek frugality may be apocryphal (9.82); and, finally, after the war, there was a mass resurrection of cooked fish (9.120).
William Lane Craig wants you to believe that, based on Herodotus, “there simply was insufficient time for significant accrual of legend by the time of the gospels’ composition.” Oh, really? You decide.
The argument described here, and all quotations, originally appeared in “Contemporary Scholarship and the Historical Evidence for the Resurrection of Jesus Christ,” Truth: an International Inter-Disciplinary Journal of Christian Thought 1 (1985), pp. 89-95, and are here taken from the version of this article provided on the web at http://www.leaderu.com/truth/1truth22.html.

I discuss proper historical method in great detail in another part of my review of In Defense of Miracles, and comment on the general failings of Christian apologists in doing history in the conclusion of my summary of that review.
Craig cites the source as Roman Law and Roman Society tn the New Testament [sic]. He must have forgot to double check his reference. The misspelled “in” is clearly just a type-o, but the real title of Sherwin-White’s book is Roman Society and Roman Law in the New Testament, 1963.
loc. cit., “The Historicity of the Gospels and Graeco-Roman Historiography,” p. 189.
A fact little-understood by non-historians is the usefulness of texts such as the NT for details of social history. In this respect, they are invaluable even if they are completely false, because any fiction must necessarily reflect the social realities or beliefs of the author and his audience. In this respect, even the most overtly fictional texts from antiquity are historically valuable.
ibid., pp. 189-90.
“As for the stories told by the Egyptians, let whoever finds them credible use them. Throughout the entire History it is my underlying principle that it is what various people have said to me, and what I have heard, that I must write down,” 2.123; see also 1.5, 4.195, and for his giving of different accounts, see, e.g., 1.3-5, 2.20-27, 5.86-87, 6.53-54, 7.148-152, for naming his sources, see, e.g., 1.20-21, 2.29, 4.14, 4.29, 5.86-87, 6.53-54, 8.55, 8.65, and for expressions of healthy skepticism, see, e.g., 2.45, 3.16, 4.25, 4.31, 4.42, 4.95-96, 4.105, 5.86, 7.152. Despite all this, Herodotus is notoriously called, today as in ancient times, the “Father of Lies” (in mockery of his more respectable title as the father of history), since in the final analysis he is not very reliable, and invents a great deal in order to create symmetries and allusions and illustrations of his moral beliefs, or passes on as fact a lot of bogus, sometimes absurd information. In this respect, the Histories does indeed serve as a good analogy for the Gospels, although the Gospels are worse, lacking even what Herodotus has in the way of critical thinking evident in his storytelling.
The decisive starting points for sources of the Persian War are C. Hignett, Xerxes’ Invasion of Greece (1963); A.R. Burn, Persia and the Greeks, 2nd ed. (1985); J.F. Lazenby, The Defence of Greece (1993); also, the Cambridge Ancient History, 2nd ed., 5.2 (1992).
Sherwin-White is being a little overly rhetorical here, and Craig would have noticed this if he had actually bothered to read the passage in Herodotus that he draws his example from. For the reasoning of Herodotus is entirely subjective, not based on any falsifying evidence, but only his analysis of the interests of certain parties: “I do not accept the story” he says (6.121), but the story itself is true, he insists, only “who it was that was the agent I cannot say” (6.124). This is not a legend Herodotus is doubting, but the truth behind a political smear campaign. It is worth noting that if Herodotus had heard the Gospel stories, he would have been equally doubtful, for the same subjective reasons, if we can judge from his reception of an account of a Thracian resurrection religion that was similar to Christianity in important respects (in having a man resurrected as a god in the flesh–after three years, rather than three days–granting immortality for believers, 4.94-6; Plato ascribed healing magic to him in the Charmides 156d-158b). Since Herodotus presumes this man to have been a slave of Pythagoras, the date of this story would be sometime around 500-530 BC, only fifty to one hundred years before Herodotus recorded the details.

In fact, these oracles were very likely political inventions by military leaders (such as Themistocles) during the war itself, making the time of their invention almost immediate, yet no one challenged them. There are many other fulfilled prophecies reported by Herodotus (cf. 8.96, 9.43). | <urn:uuid:fc9ff1fe-d598-47aa-a823-e6629524e463> | CC-MAIN-2024-51 | https://infidels.org/library/modern/richard-carrier-herodotus/ | 2024-12-01T20:51:18Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066036672.6/warc/CC-MAIN-20241201192453-20241201222453-00100.warc.gz | en | 0.965631 | 6,773 | 2.53125 | 3 |
Telecommunication Technology – Telemedicine
One of the major challenges facing the healthcare system is provision of quality medical care to a large section of the population, which does not have access to the medical personnel due to geographic limitations and other socioeconomic barriers. However, information technology has offered the potential to affect the type of information and knowledge available to patients and consumers (Davis & LaCour, 2014). Growth and proliferation of the Internet-accessible sources of information have significantly modified the role of health services providers and patients. In order to overcome geographic barriers to provision of health services, technology has been significantly adopted in the healthcare system and its wide range of array has demonstrated as an effective way of overcoming specific barrier care, particularly in remote areas (Davis & LaCour, 2014). Therefore, it is apparent that the use of technology has significantly transformed delivery of healthcare services. The paper will analyze and evaluate utilization of innovative systems and patient care technology is the delivery of healthcare services.
In the last few decades, hospitals have strived to extend their health services to remote areas. As a result, application of telemedicine has spread rapidly in the healthcare sector and has now become integrated into on-going operations of hospitals, private physicians, specialty departments, consumer homes, and workplaces (Capello, Naimoli, & Pili, 2014). Telemedicine is the use of medical information that is exchanged from one side to the other through the use of electronic communications to enhance the patient’s clinical health status. It encompasses a wide range of applications and services that include the use of email, two-way video channels, wireless tools, as well as other forms of telecommunication technology.
The Use of Telemedicine
The use of telemedicine in healthcare services delivery is usually based on two concepts: synchronous (real-time) and asynchronous (store- and- forward). Through these two concepts, it is usually possible to provide healthcare services to individuals in different geographical localities. However, real-time telemedicine requires both a patient and a physician to be at the communication link at the same time, thus allowing real-time interaction to take place. In real-time telemedicine, the use of video-conferencing equipment represents the most common technology used in the provision of healthcare (Capello et al., 2014). Besides, there is medical equipment attached to video conferencing equipment that facilitates patient-physician interaction. For instance, a tele-otoscope permits the remote medical personnel to view the inside of the patient’s ear while the tele-stethoscope enables the physician to listen to the patient’s heartbeat. In addition, telemedicine is also achieved through an asynchronous concept that involves acquiring medical information and then transmitting the data to the medical specialist at a convenient time for assessment offline (Capello et al., 2014). The concept is considered beneficial, especially to individuals of low socioeconomic status since it does not require both physician’s and patient’s presence at the same time. It is usually common in specialties such as pathology, radiology, and dermatology.
Barriers to Telemedicine Adoption
Although the use of telemedicine in the healthcare system continues to grow, there are numerous barriers that continue to hinder its adoption and use in delivery of healthcare services. The use of telemedicine, especially video-conferencing, requires a high bandwidth internet connection. However, most areas lack high-speed Internet connection that supports the use of some of the telemedicine functionalities (Capello et al., 2014). Since remote healthcare service delivery requires high-speed connection, many rural hospitals and patients lack access to an adequate network infrastructure essential to establishing a proper telemedicine connection. Besides, there are a number of legal issues that affect the adoption and use of telemedicine. Such issues largely focus on the uncertainty in regard to services reimbursement, multistate licensure, as well as malpractice liability. Such aspects continue to hinder the adoption and use of telemedicine despite the presence of numerous promising bills in the Congress (Capello et al., 2014). Furthermore, there have been some issues of technology comfort where the end-user is uncomfortable with the technology, which is an aspect that makes it difficult to use this technology. Since the whole industry has for long focused on face-to-face delivery of health services where real-time collaboration has been impossible, changing such mindsets has become an impediment toward the adoption of telemedicine as a core part of health services delivery (Capello et al., 2014).
Internet-Based Health Information from Patient to Primary Care Provider (PCP)
Internet has increasingly become a useful source of information for the patient. According to the research conducted by the American Life Project, approximately 81 percent of American adults search health-related topics on the Internet. Though the use of the Internet has facilitated creation, dissemination, and accessibility of the health information, the infinite bound of cyberspace has resulted in addition of unchecked, disorganized, and misleading information that could be detrimental to the consumer’s health (Davis & LaCour, 2014). Many medical practitioners believe health information on the Internet to be problematic since they feel it generates misinformation and an inclination towards dangerous self-diagnosis among patients (Goldberg, 2010). However, other studies have shown that patients using the Internet are often more compliant, experience better medical outcomes, and ask a specific question during their appointment (Davis & LaCour, 2014). However, it is increasingly important to ensure that patients obtain appropriate information from credible websites that offer medical information.
Recommended Website for Individual with Cervical Cancer
Cervical cancer is one of the most common non-communicable diseases that affect women and ranks 14th in frequency in the USA. According to recent data, for the period between 2008 and 2011, the incidence rate for the cervical cancer increased by 8.1 cases per 100,000 women every year. In 2012, approximately 12,200 women were diagnosed with cervical cancer (Sultz & Young, 2014). Due to the increased number of cervical cancer cases, awareness and demand for information have been on the rise. However, there is a number of websites that provide credible information. Such sites include Mayo Clinic, MedlinePlus, and National Cancer Institute’s websites. National Cancer Institute’s website provides updated information that is based on dedicated research, hence providing credible information (Davis, 2013). Furthermore, the information is provided in a user-friendly language that is understandable by an individual without medical knowledge. MedlinePlus pages consist of carefully prepared web sources with health information for more than 900 health topics, including cervical cancer. Furthermore, it includes detailed information with numerous links to over 4,000 articles about the disease, test, symptoms, and treatment (Davis, 2013). MayoClinic’s website provides proven medical information from more than 3,300 physicians, researchers, and scientists from the Mayo Clinic who share their knowledge and expertise about various diseases.
Patient Education on the Internet
Health information is very important since it empowers consumers, thus permitting them to make important health decisions. However, it is essential to educate the patient on the most appropriate way of getting credible information (Khoumbati, Dwivedi, Srivastava, & Lal, 2010). The patient needs to seek information or journals with an identifiable source or author. Besides, the credibility of medical information is usually enhanced if it is provided by a medical institution, an institution of higher learning, or a government body. Such entities bring together medically knowledgeable personnel who publish verified information. Moreover, it is essential for the patient to check information in the publication that has been peer-reviewed by a panel of medical professionals, which is an aspect that adds credibility to the information (Khoumbati et al., 2010). Furthermore, the patient needs to avoid information without any identifiable publishers unless it is supported by information from other credible sources. The accuracy of medical information is largely based on supporting empirical evidence.
Criteria for a Reputable Health Information Website
There are a number of parameters used to assess credibility of a website providing health-related information (Goldberg, 2010). Assessing the credibility of the website is essential since the content on the internet is usually unregulated. It is essential to determine accuracy of the information presented. The information should be based on sound medical investigation and it should be possible to verify the information through another source. Besides, the source used needs to be cited, which makes it possible to determine accuracy of the information provided. It also essential to determine the authority of the website based on the publisher’s reputation and credentials (Goldberg, 2010). For instance, an article published by the Mayo clinic carries more authority than Wikipedia. Moreover, the information needs to be complete, objective, updated and structured in a way that reflects different perspectives of the issues under investigation.
Personal Health Record (PHR)
Personal health record (PHRs) is consumer-centric instruments that are used by individuals to communicate with their health services provider in the management of their own health. It documents individual’s or family member’s personal information, health condition, medicines, health care provider, medical tests, and special needs as a part of the person’s medical history (Al-Ubaydli, 2011). The alliance for nursing informatics emphasizes the use of personal health records as an element of reducing medical errors and enhancing the quality of care, accessibility, and efficiency in the health care system. There is a wide range of benefits associated with the use of personal medical records (PHR).
Benefits of a Personal Health Record (PHR)
Maintaining a personal health record is beneficial since it permits the physician to get individual’s accurate medical records. It permits better patient-physician interaction, as well as with other medical personnel such as a pharmacist and nurses. It is apparent that most people find it difficult to remember exactly treatment they have received throughout the years and when it occurred particularly. As a result, this makes the doctor repeat medical tests unnecessarily (Al-Ubaydli, 2011). The use of PHR saves a lot of time and money and permits the physician to access information that shows changes in the individual’s health. For individuals with a chronic illness, maintaining an individual health record makes it possible to track symptoms and progress on individual medical conditions. It is usually essential when an individual has been seeing a different medical specialist, which makes it possible for a different physician to have a point of reference (Khoumbati et al., 2010). Studies indicate that patients using PHRs have been able to manage diabetes between clinic visits via consultations with their health services providers. Patients have also been able to learn how lifestyle choices affect diabetes by using the system (Al-Ubaydli, 2011).

PHR permits access to the patient’s information during medical emergencies. PHR usually contains information about allergies, confirmed diseases, and a list of medications. In case of a medical emergency, such information can be accessed by another person, thus quickening delivery of life-saving care (Al-Ubaydli, 2011). Furthermore, it has been established that adoption of PHRs in medical guidelines for health management improves consumers’ health behaviors such as regular exercise, dietary changes, and improved medical compliance.
Barriers to Personal Health Records (PHR) Adoption
Although health care associations and alliances emphasize the need to adopt and maintain health personal records, a number of barriers have been found to slow down the adoption process. There has been a concern regarding the accuracy and reliability of the data when patients can enter the system and update the data (Khoumbati et al., 2010). For instance, a study conducted on integrated PHR in San Francisco has revealed that laboratory results and the list of medication were incomplete and inaccurate (El Emam, 2013). As a result, it has been recommended that patients must be able to review and ascertain information provided and alert the health provider in case of discrepancies. However, such data discrepancies limit the adoption and use of PHRs (El Emam, 2013).
Required Safety and Security Provisions for PHRs
One of the key impediments to the adoption and use of Personal Health Records (PHRs) revolves around data privacy and security. There has been an increasing need to regulate how patient data are handled and shared within the health care industry. In response, Health Information Technology for Economic and Clinic Health Act (HITECH) has expanded privacy and security protections of the HIPAA Act to the PHR providers (Morrison & Furlong, 2014). However, the HITECH offers many uncertainties regarding PHRs. Hence, most privacy policies of the PHR system fail to provide an in-depth description of security measures essential to safeguard patient data. Therefore, it is essential for the privacy rule to regulate how individuals’ health data are held by the HIPAA-covered entities to avoid misuse of these data (Morrison & Furlong, 2014). Besides, it is essential for the HITECH to expand an individual’s rights in regard to their health information to ensure that individuals can gather information from multiple sources. Ethically, health providers are warned against inappropriate access of the PHR data by the code of ethics. According to the American Nurses Association, nurses have a duty to protect the patient’s confidentiality (Morrison & Furlong, 2014).
In conclusion, it is apparent that the integration of technology in the delivery of health care services has changed the way care is delivered to patients. It is now possible to provide a wide range of medical services through telemedicine, which makes it possible to avail such services to remote areas. Furthermore, technology has increased patients’ access to information, which allows them to manage their medical conditions better. However, there is a need to educate consumers on the criteria of searching medical information only on accredited websites in order to prevent their access to unverified information that could have detrimental outcomes in case of self-diagnosis and self-medication.

This ambitious work by John Chambers and Jacqueline Mitton endeavors to capture the history and development of the solar system in the class of science. The evolution and birth of the existing solar system remains a subtle mystery that requires mild interactions among scholars to deduce. This tantalizing mystery is believed to unfold the underlay interjections about the origin of human being. This book provides a remarkable narration about how different celestial objects that constitute the solar system originated from small beginnings several years ago (Esposito, 2015). Similarly, it reveals different attempts the philosophers and scientist have put in place to seek and unravel this false innuendo across many centuries ago. They piece together several clues that are capable of to reveal the actual layout of the solar system as they fathom the possible formation of the solar system.
As its two titles suggest, the set to illustrate 'The Origin and Evolution of the Solar System' as portrayed in the vast scientific descriptions through generation at presents what we see today. As told by science writer Jacqueline Mitton through several scientific disciplines such as chemistry, biology, physics among others and John Chambers who is a renowned planetary scientist. Due to dual authorship, the book is excellently structured, lucid and seamless. Notably, it the most pleasant way of placing science before novice and enthusiastic readers in an appealing and approachable manner about writing craftsmanship.
Based on the latest findings in the planetary science and astrophysics in conjunction with the history of astronomy, Jacqueline Mitton and John Chambers offer an authoritative and explicit up-to-date treatment of all available objects that can be used to fathom the actual history of the solar system and its build up. They assess the process of universe evolution and set an appropriate stage concerning the position of the sun and how gas and dust that make up the dark cloud which accompany the appearance of the young sun transgress and changes to moons, comets, asteroids, and planets as they exist today. The two writers explored to deduce the process in which different worlds acquire their different unique characteristics and why some are gaseous, and others are rocky. Additionally, they examine why the Earth, in particular, provides the perfect haven which gives a better ground for life emergencies.
From Dust to Life is a fascinating book the captures attention of most readers to explore through pages especially scientists with patient desires to learn more about the existence of the solar system and how it came to exist. This enticing work takes learners to the highest point of modern research through proper engagement with recent debates and controversies. It deduces the processes of discovery of many planetary systems and other planets that are traced from far-distant extrasolar. This provides such learners with a transformed understanding based on the extraordinary history of our own solar and its possible fate.
These authors approach of exploring a specific solar system aspect and setting out different principles based on scientific research at a given time helps readers to understand the nature of solar system across history (Esposito, 2015). Different ideas will be easily retrieved based on the topic as the readers surge further in their research endeavors. As they approach the present day, all sections them pass provide detailed information which reflects and describes current research for a better direction in the future.
Related issues like the formation of the star are also discussed in details in the light of available evidence retrieved from far beyond records about the solar system although a link to their topic of interest is well outlined. They focus was to ensure that at the end the reader is capable of making a unified overview of all that is known about the existence of the solar system and its components.
Moreover, the also provides a key takeaway about the formation of the planet as a cohesive dynamic as opposed to a simplified format that different models taught in recent past. Mainly, it now downs on many scientists that the formation of the solar system was responsible for migration of planets, a case that is illustrated through the discovery of new solar systems that have character traits interchangeably. For example, Jupiter has been revealed to be the largest, a size of the world and is closely orbiting the sun. In the solar system, especially the grand tract model, Jupiter has been questioned about its closeness with the sun. It approaches to the sun has been measured to be approximately 1.5 AU. This was the actual distance between Jupiter and the sun before several other planets like Saturn (Chambers & Mitton, 2017). Notably, it is the planet Saturn that caused a reverse to the direction of Jupiter to the position it is today which is approximately 5.2 AU. Both the outward and the inward migration of these planets explained the relative size of the planet Mars as the smallest of the three. Similarly, the movement was responsible for clearing out many materials that were present in the asteroid main belt.
Additionally, the French city Nice Model which shows the place of the work's development, predicts that the other four outer planets were formed close to each other. However, the present of icy planetesimals and complex interactions in the gravitational pull made most of them disintegrate to their present orbits as others many others are being scattered into the innermost parts of the solar system. This later led to the creation of an ancient heavy bombardment which prevents a resurface of mars, mercury, and the moon to present what the form we see today in the solar system through mild attempts of reshaping the formation and nature of life as experienced on Earth today. The complexity in the gravitational interaction was necessary to unite planets together while revealing the characteristics that make them is in the position they are today. Generally, it is clear that complex interaction changed the shapes of many planets and gave their unique ones. The writer makes new cutting edges in the research so that readers can easily relate the information they have attained from the book with other scientific works. The solar system is explicitly discussed as well as other components that constitute a substantial network. Similarly, the final chapter portrays an outstanding way to revise and update any misinterpretations that could be made on the solar system existence (Chambers & Mitton, 2017). The brightness and dimness in colors that are seen in different planets which are far from the sun show that the strength of the interaction was not compact to get enough light. The position of the planets also reveals the power of the gravitational interaction. The higher the gravitational interaction the far the location of the planets from the original post and consequently its original form.
Mitton and Chambers stay focused in their book, From Dust to Life: As opposed to other literature books that build stories from scientist and other scientific disciplines, the discuss the history of science and how it came to exist and develop rather than depending on claims that an individual was responsible for making such scientific accounts to happen. This was an orchestrated transaction: while many theories record different proofs about the development in science especially the solar system. It remains vivid from the book that nothing comes for a vacuum. There must be a gradual development accompanied by an excellent explanation to support all claims. Besides, the readers are supposed to be fed with facts, not little errands that are baseless and cannot be reviewed for future studies. Similarly, from the claims in the scientifically developed novice scientist can find an enticing way to defend their applications as well as [provide overt supports and references. The complexity in explaining the nature of science and its development is best served with less fascination.
However to have such discoveries in planetary science, one needs to be well conversant with all planets, the smaller bodies, and the moon which constitute the solar system. Most people have a fixed mind about the basic concept in the formation of the solar system thus bars them from exploring to get the actual truth as contained in science catalogs. The process is very chaotic, but readers and novice researchers must remain vigilant to attain the best from the many confusing episodes that accompany the development and formation of the solar system. Generally, this development and resurgences in the scientific ratification have led to an increasing sophistication in the computer models thus tearing apart some vital information that learners may grasp. Also, it offers an explicit understanding of the several processes which explain the existence of the solar system.
The most exciting part of the book, From the Dust to Life, is from the description of several controversies, ambiguities add doubts by Frank. Similarly, the story of the orbiting position of other planets due to the gravitational interaction which makes Earth outstanding provides a pleasant concoction. The writer makes new cutting edges in the research so that readers can easily relate the information they have attained from the book with other scientific works. The solar system is explicitly discussed as well as other components that constitute a substantial network. Similarly, the final chapter portrays an outstanding way to revise and update any misinterpretations that could be made on the solar system existence. The result from other scientific sources is well outlined and used to build coherency in the books. This allows readers to be insightful to explore other planets. Different picture in the book made it attractive as readers could relate what they have read to what is present in the map.
The book is also eloquently written and understandable. The chronological development of event is coherent. Creation of the book in subtitles relieves readers from unnecessary boredom that is common in reading a continuous novel. Besides, each subheading develops from a unique point but and the end returns to the main topic of study thus allowing readers to fathom further. The authors have employed simple language with well-structured sentences that are easy to read. Word choice is superb, and most complex scientific words are explained in details for easy understanding as on peruse through the pages of the book. The translation of the book liberally in its texts illustrates the author's contentions thereby creating a well-documented and balanced work whose purpose is easy to achieve and realize. Additionally, the subject is well explained through the use of many researchers and writers with the same interest in the same scientific study although the title might seem complicated.
Some people may find the book unpleasant because it is depressing due to its many numbers of pages. The relationship between the topic and the subject is a bit confusing. It requires a comprehensive analysis to distinguish why the authors chose to compare the solar system with dust and life. The dual authorship with different areas of profession challenges the reader to develop a cohesive conclusion from the book. Some facts may be ambiguous due to such differences. A most scientific word used requires one to have known the solar system and its components. The existence of that sun as the most prominent planet is a greater mystery to...

If the liquid culture appears cloudy or has a significant change in color, it is likely that it has been contaminated with unwanted microorganisms. Additionally, if you notice any clumps or unusual growth patterns, it may indicate the presence of bacteria or fungi.
Another indicator of a spoiled liquid culture is a foul odor. If the liquid culture emits a strong, unpleasant smell, it is a clear indication that something is not right. The odor can range from a mild off-putting scent to a pungent, rotten smell. This odor is usually caused by the metabolic byproducts of bacteria or fungi present in the culture. It is crucial to trust your sense of smell and discard any liquid culture that has an unusual or foul odor.
Abnormal Growth Patterns
In addition to visual changes and foul odors, abnormal growth patterns can also signal spoilage in liquid culture. When examining the liquid culture, look for any unusual formations, clumps, or floating particles. These abnormal growth patterns can be an indication of contamination or the presence of unwanted microorganisms. Healthy liquid culture should have a consistent and uniform appearance.
It is important to note that even if the liquid culture does not show any obvious signs of spoilage, it is still necessary to exercise caution. Microbial contamination may not always be visible to the naked eye, and the absence of visual changes does not guarantee the absence of contamination. Therefore, it is crucial to follow proper storage and handling procedures to minimize the risk of spoilage.
Regularly inspecting the liquid culture for any signs of spoilage is essential to ensure the success of your experiments. By promptly identifying and discarding spoiled liquid culture, you can prevent contamination and maintain the integrity of your research.
In the next section, we will discuss how to extend the shelf life of liquid culture through proper storage techniques, sterilization methods, and regular monitoring and maintenance.
Stay tuned for the upcoming section: “V. Extending the Shelf Life of Liquid Culture.”
Extending the Shelf Life of Liquid Culture
Liquid culture is a valuable tool for many industries, including microbiology, biotechnology, and food production. It allows for the growth and maintenance of microorganisms in a liquid medium, providing a convenient and efficient way to study and utilize these organisms. However, like any other perishable product, liquid culture has a limited shelf life. To make the most of this valuable resource, it is important to understand how to extend its shelf life through proper storage, sterilization, and regular monitoring.
Proper Storage Techniques
One of the key factors that affect the shelf life of liquid culture is storage conditions. Proper storage techniques can significantly extend the lifespan of liquid culture. Here are some guidelines to follow:
Temperature: Liquid culture should be stored at a consistent and controlled temperature. The ideal temperature range for most liquid cultures is between 2-8°C (36-46°F). This temperature range helps to slow down microbial growth and preserve the culture for a longer period.
Light Exposure: Exposure to light can have a detrimental effect on the stability of liquid culture. Therefore, it is important to store liquid culture in opaque containers or wrap them in aluminum foil to protect them from light.
Air Exposure: Oxygen can also negatively impact the shelf life of liquid culture. To minimize air exposure, it is recommended to store liquid culture in airtight containers or bottles with tight-fitting lids or caps.
Contamination is a major concern when it comes to liquid culture. Sterilization methods play a crucial role in preventing contamination and extending the shelf life of liquid culture. Here are some commonly used sterilization techniques:
Autoclaving: Autoclaving is a widely used method for sterilizing liquid culture. It involves subjecting the culture to high-pressure steam, which kills any microorganisms present in the liquid. Autoclaving is effective in eliminating both vegetative cells and spores.
Filtration: Filtration is another popular method for sterilizing liquid culture. It involves passing the culture through a filter with a pore size small enough to trap microorganisms. This method is particularly useful for heat-sensitive liquids.
Chemical Sterilization: Chemical sterilization involves the use of disinfectants or sterilizing agents to kill or inhibit the growth of microorganisms. Commonly used chemicals include ethanol, hydrogen peroxide, and bleach. However, it is important to follow proper protocols and guidelines when using chemical sterilization methods to ensure the safety and effectiveness of the liquid culture.
Regular Monitoring and Maintenance
Regular monitoring and maintenance are essential for extending the shelf life of liquid culture. Here are some practices to consider:
Quality Control: Regularly test liquid culture for contamination and viability. This can be done through visual inspection, microbial testing, or other appropriate methods. Promptly discard any cultures that show signs of contamination or degradation.
Periodic Subculturing: Subculturing involves transferring a small portion of the liquid culture to fresh growth medium. This helps to rejuvenate the culture and prevent the accumulation of waste products and toxic metabolites. Regular subculturing can help maintain the vitality and longevity of the liquid culture.
Record Keeping: Keep detailed records of the storage conditions, sterilization methods, and maintenance procedures for each liquid culture. This information can help identify any patterns or issues that may arise and allow for adjustments to be made accordingly.
By following these guidelines for proper storage, sterilization, and regular monitoring, you can extend the shelf life of liquid culture and maximize its usefulness. Remember, a well-maintained liquid culture can provide consistent and reliable results, leading to better outcomes in research, production, and other applications.
Common Misconceptions about Liquid Culture Shelf Life
Liquid culture is a popular method used in various industries, including microbiology, biotechnology, and food production, to cultivate and grow microorganisms. It provides a nutrient-rich environment that promotes the growth and multiplication of microorganisms. However, there are several misconceptions surrounding the shelf life of liquid culture. In this section, we will debunk these misconceptions and shed light on the truth.
“It lasts indefinitely”
One common misconception is that liquid culture lasts indefinitely. While it is true that liquid culture can have a relatively long shelf life compared to other forms of culture, it is not everlasting. The shelf life of liquid culture depends on various factors, such as the type of culture and storage conditions. Over time, the nutrients in the liquid medium can degrade, making it less suitable for the growth of microorganisms. Additionally, the viability of the microorganisms can decline, leading to reduced growth and productivity.
“It can be used even after the expiration date”
Another misconception is that liquid culture can be used even after the expiration date. Expiration dates are determined based on rigorous testing and quality control measures. They indicate the period during which the liquid culture is expected to maintain its optimal performance. Using liquid culture beyond the expiration date can result in poor growth, contamination, and compromised results. It is essential to adhere to the expiration date to ensure the reliability and accuracy of your experiments or production processes.
“All liquid cultures have the same shelf life”
Liquid cultures can vary significantly in their shelf life. Different types of liquid culture formulations and microorganisms have different requirements and stability. Some liquid cultures may have a shorter shelf life due to the nature of the microorganisms or the composition of the medium. It is crucial to consult the manufacturer’s guidelines or conduct stability studies to determine the specific shelf life of a particular liquid culture.
To maximize the shelf life of liquid culture and ensure optimal results, it is essential to follow proper storage techniques, sterilization methods, and regular monitoring and maintenance.
Proper storage techniques: Liquid culture should be stored in a cool, dark place to minimize exposure to light and heat, which can degrade the nutrients and compromise the viability of the microorganisms. It is recommended to store liquid culture in a refrigerator or a dedicated cold storage unit at the appropriate temperature.
Sterilization methods: Contamination is a significant risk that can shorten the shelf life of liquid culture. Proper sterilization techniques, such as autoclaving or filtration, should be employed to eliminate any potential contaminants. It is crucial to maintain a sterile environment during the preparation, handling, and storage of liquid culture.
Regular monitoring and maintenance: Regularly inspecting liquid culture for signs of contamination or degradation is essential. Visual changes, foul odors, and abnormal growth patterns are indicators of a spoiled liquid culture. If any of these signs are observed, it is best to discard the culture and start fresh.
In conclusion, understanding the common misconceptions about liquid culture shelf life is crucial for maintaining the quality and reliability of your experiments or production processes. Liquid culture does not last indefinitely, should not be used after the expiration date, and different cultures have varying shelf lives. By following proper storage techniques, sterilization methods, and regular monitoring, you can extend the shelf life of liquid culture and ensure optimal results. | <urn:uuid:3e55f53c-22ce-4c27-b45f-d6b36e6a0c8c> | CC-MAIN-2024-51 | https://sciencesphere.blog/liquid-culture-duration-guide/ | 2024-12-01T20:05:03Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066036672.6/warc/CC-MAIN-20241201192453-20241201222453-00100.warc.gz | en | 0.916825 | 3,545 | 3.421875 | 3 |
When were Roman gold coins minted?
There are two main Roman gold coins: the aureus and the solidus. The aureus was first minted during the late Roman Republic around 211 BC. Initially produced in limited quantities, it remained very rare until the late Republic. Its significance grew during the Empire, especially after the monetary reforms implemented by Emperor Augustus. This gold coin continued to be used until the early 4th century when Constantine I introduced the solidus as part of his monetary reforms. The solidus then became the standard gold coin for the Roman and Byzantine Empires for centuries.
Gold coins like the aureus and the solidus played a crucial role in the Roman economy. They were used for large transactions, military payments, and as a store of value. Their high value promoted economic stability, enabling more efficient tax collection and troop payments, essential for maintaining the vast Roman Empire.
What factors led to the adoption of gold as a material for minting coins?
The adoption of gold as a material for minting coins was driven by several key factors. Firstly, gold’s intrinsic value and scarcity made it an ideal medium for high-value transactions and long-term savings, ensuring the coins retained their worth over time. Its durability and malleability allowed for the creation of detailed and long-lasting coins that could withstand extensive handling without significant wear. The universal recognition and trust in gold as a valuable commodity also facilitated trade and commerce within the Roman Empire and with foreign merchants, as gold coins were widely accepted and respected. Moreover, gold coins played a crucial role in providing economic stability, a vital factor for managing the Roman Empire’s complex economy. Lastly, the use of gold also symbolised wealth and prestige, reinforcing the power and legitimacy of rulers who issued these coins.
What was the role and significance of gold coins in the Roman Republic?
During the late Roman Republic, the most relevant gold coin was the aureus, which became increasingly significant toward the end of the Republic. Despite its growing importance, gold coin issues remained relatively rare and did not play a major role in the broader economy. Still, the possession of gold coins was a symbol of wealth and status, often associated with the elite classes. The aureus also helped in the centralisation of power, as it was controlled by the state and used to finance military and political activities, thereby reinforcing the government’s influence over the economy.
These early gold coins are among the rarest and most valuable in Roman numismatics. They feature designs with significant symbolic content for the Republic, such as the well-known scene of the oath, as well as depictions of divinities like Janus, Mars, and Jupiter. Toward the end of the Republic, during the period of the Imperators, portraits of generals became widespread on coins, which were used as a means of propaganda.
What were the monetary reforms introduced by Augustus, and how did they impact gold coinage?
Emperor Augustus implemented significant reforms in the Roman monetary system, aiming to stabilise the economy and strengthen the financial foundations of the newly established imperial system. Silver, with the denarius as its standard unit, lost prominence to gold, with the aureus becoming the primary unit. Augustus set the value of gold at 25 denarii per aureus and reintroduced it with consistent weight and purity. A crucial factor in this rise of gold was the access to large gold mines, such as those in the northwest of Hispania.
In terms of design, the obverse of the aureus minted under Augustus bore images that promoted the emperor’s achievements and the values of the Roman state, such as the image of Augustus himself and symbols of peace and prosperity. The reverse side depicted various symbols and deities representing Roman virtues, military victories, or significant events. For instance, coins might feature the goddess Victory or an altar of peace, symbolising the emperor’s role in maintaining stability and order.
How Did Gold Coins Evolve in the Imperial Era?
Gold coinage continued to evolve under the early emperors, with each ruler adding their personal touch to the design. Tiberius maintained the monetary reforms of Augustus, keeping the aureus stable. Caligula introduced new imagery that reflected his controversial reign, while Claudius emphasised themes of justice and stability. Nero, known for his extravagant spending, debased the aureus by reducing its gold content, leading to a decline in the coin’s value and a shift in economic stability. While the design of gold coins evolved under different emperors, certain continuities remained. The consistent portrayal of the emperor on the obverse side established a tradition of imperial representation. However, differences in the reverse imagery and inscriptions reflected the priorities and achievements of each ruler.
How Did the Crisis of the Third Century Affect Roman Gold Coinage?
The Crisis of the Third Century was a tumultuous period that began in 235 with the assassination of Emperor Severus Alexander. This event triggered a series of conflicts that nearly led to the collapse of the Roman Empire. As the empire faced financial strain due to constant warfare, political instability, and invasions, the authorities responded by reducing the gold content and weight of the aureus. Originally, this coin had a standard weight of about 8 grams and a high gold purity. However, to cope with the empire’s fiscal demands, the weight of the aureus was gradually decreased. By the mid-3rd century, the weight had dropped to approximately 7 grams and the gold content was reduced, leading to a decrease in their intrinsic value and undermining their role as a stable medium of exchange. This instability was further exacerbated by the widespread production of coins with inconsistent gold purity, leading to variations in value and contributing to broader economic uncertainty.
What were the most important gold coins of the Crisis of the Third Century?
During the Crisis of the Third Century, several gold coins emerged, reflecting the era’s economic instability. Key among these were the aurei issued by the Gallic Empire, led by emperors such as Postumus and Tetricus I. These coins, though significant for their regional authority, often suffered from variable gold content and weight due to the empire’s strained resources. Similarly, the Palmyrene Empire, under Queen Zenobia and her son Vaballathus, minted aurei that displayed the portraits of the ruling figures and symbols of Roman virtues, but these also experienced issues with consistency and purity. When Emperor Aurelian managed to reunite the fractured empire (270–275), he issued aurei that aimed to restore stability to the currency. These coins featured his portrait and celebrated his military victories and efforts to restore order. Despite Aurelian’s attempts, the aurei still bore traces of the previous debasements. Later, during the reign of Probus (276–282), aurei continued to reflect the period’s attempts at economic recovery. Probus’ coins often portrayed military imagery or symbols of renewal, representing his efforts to address the empire’s financial and military crises.
What were the monetary reforms introduced by Diocletian, and how did they impact gold coinage?
Emperor Diocletian introduced a series of significant monetary reforms that aimed to stabilise the Roman economy, which had been severely disrupted during the Crisis of the Third Century. To begin with, he standardised the weight of the aureus at approximately 1/60 of a Roman pound (about 5.45 grams) and improved its purity, restoring confidence in the currency that had been undermined by frequent debasements. Additionally, he introduced a new silver coin, the argenteus, and revalued the denarius. He also introduced new bronze coins, such as the follis, to provide a stable medium of exchange for everyday transactions. To combat rampant inflation, Diocletian implemented the Edict on Maximum Prices in 301, setting price limits for goods and services across the empire. Although the Edict was difficult to enforce and had limited long-term success, it was part of a broader strategy to restore economic stability and public confidence. All of these reforms laid the groundwork for future economic stability and set a precedent for subsequent emperors.
What were the characteristics of the solidus introduced by Constantine and how did it compare in use and stability to earlier gold coins?
The solidus, introduced by Emperor Constantine I in 312, was the main gold coin of the monetary system of the late Roman and Byzantine Empires. Weighing approximately 4.5 grams and struck with 95-98% gold purity, it featured a portrait of the emperor on the obverse and symbols of the empire’s power and divine favour on the reverse, such as deities, victories, or monuments. The introduction of the solidus marked a significant improvement in stability and reliability compared to earlier gold coins like the aureus, which had suffered from frequent debasements and reduced gold content. Thus, it became a trusted medium of exchange, even during periods of economic and political turmoil, facilitating large-scale transactions, international trade, and military payments with greater efficiency and reliability than previous gold coins. Its stability helped lay the foundation for a more secure and predictable financial environment. Moreover, its durability and trustworthiness ensured its use for centuries, not only within the Roman Empire but also in neighbouring regions and later in the Byzantine Empire.
What were the main characteristics of the last gold coin issues of the Western Roman Empire?
The last gold coin issues of the Western Roman Empire, struck during the late 4th and early 5th centuries, exhibited several characteristics that reflected the empire’s declining power. The primary gold coin of this period remained the solidus, which maintained its weight of approximately 4.5 grams and high gold purity of 95-98%, consistent with the standards set by earlier issues. A third of the solidus is the tremissis, which also continued to be issued for a long time afterwards by the Byzantines and Visigoths.
The designs of these later coins often became less refined compared to earlier issues and much more repetitive, frequently featuring the Emperor, Roma, and Victoria among the most common themes. The obverse typically featured the portrait of the reigning emperor, although the artistry was generally cruder, reflecting the declining resources and skilled craftsmanship available. The reverse side depicted symbols of imperial authority and Christian iconography, including crosses and chi-rho symbols, emphasising the increasing influence of Christianity in the empire. Economic turmoil also led to irregularities in coin production, with mints operating under challenging conditions, resulting in coins with less precise weights and variable gold content. Despite these issues, the solidus remained relatively stable compared to other denominations.
How Did Gold Coins Transition and Evolve in the Byzantine Empire?
Gold coins in the Byzantine Empire transitioned and evolved significantly from their Roman predecessors. To begin with, the solidus continued to be the standard gold coin throughout the Byzantine period, maintaining a consistent weight of approximately 4.5 grams and high gold purity. The solidus was eventually renamed the nomisma and later, the hyperpyron, during the reign of Alexios I Komnenos in the 11th century. The hyperpyron weighed less and had a slightly lower gold content than the original solidus. The imagery of Byzantine gold coins also evolved. Early Byzantine coins continued the Roman tradition of featuring the emperor’s portrait on the obverse, but they increasingly incorporated Christian symbols. Over time, the iconography became distinctly Byzantine, with images of Christ, the Virgin Mary, and various saints appearing alongside or instead of the emperor’s portrait.
How do Roman gold coins compare to Byzantine gold coins?
Roman and Byzantine gold coins, while sharing a common heritage, exhibit notable differences in design and usage. The primary gold coin of the Roman Empire was the aureus, later replaced by the solidus in the early 4th century. The aureus weighed around 8 grams, while the solidus weighed approximately 4.5 grams and was known for its high purity. The Byzantine Empire continued using the solidus, renamed the nomisma, and later introduced the hyperpyron in the 11th century. In terms of design, early Roman coins typically featured portraits of emperors on the obverse and symbols of the empire’s power, military victories, and deities on the reverse. Early Byzantine coins continued the Roman tradition but increasingly included images of Christian iconography. Moreover, the stability of Roman gold coinage varied greatly as debasement and reductions in gold content were common. The Byzantine solidus generally maintained the standards set by Constantine, ensuring economic stability and widespread acceptance. | <urn:uuid:35ae032d-6af2-43aa-b391-16d7618e17cd> | CC-MAIN-2024-51 | https://social.vcoins.com/romancoins/roman-gold-coins-origin-and-evolution/ | 2024-12-01T21:31:02Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066036672.6/warc/CC-MAIN-20241201192453-20241201222453-00100.warc.gz | en | 0.964764 | 2,593 | 3.84375 | 4 |
In Tutorial thirteen we showed that relativity is invalid, because the spherical wave proof failed. The proof’s failure means that Einstein did not demonstrate the compatibility of his two postulates. In fact, the failed proof shows that his two postulates – the principle of relativity and the principle of the constant velocity of light – are not compatible. Although relativity is a failed theory, any analysis of Einstein’s work is incomplete without an explanation of relativity’s most important concepts: time dilation, length contraction, and the limitation on the speed at which something moves. In this tutorial, we examine how motion would be explained if his two postulates were actually compatible.
Before we look at Einstein’s concepts, we have to explain the difference between absolute and relative measurements. Imagine a bus traveling at 50km/s. A car is driving next to the bus in the same direction and at the same velocity. With respect to someone standing on the sidewalk, the car is moving at 50km/s. However, from the perspective of a passenger sitting in the bus, the car appears stationary because it is neither pulling away from nor falling behind the bus. From the passenger’s perspective, the car appears to be moving at 0km/s. In general, measurements taken with respect to the stationary system are called absolute measurements. Measurements made from the perspective of a moving system are called relative measurements. The idea of using relative measurements to explain motion is where relativity gets its name.
Once again we introduce an example involving a bus, a jogger, and a street. To this example we now add a stationary observer who is standing on the sidewalk and a moving observer who is in the bus.
An observer is simply someone who performs his or her measurements from the perspective of one–and–only-one system. The first observer, placed on the sidewalk, is called that stationary observer. He makes his measurements using a ruler embedded in the street. The second observer, placed on the bus, is called the moving observer. He makes his measurements using a ruler embedded in the floor of the bus. It is often easier to describe relative measurement in terms of an observer rather than the more verbose “using the ruler embedded in the…”
With the bus stationary, we place the jogger in motion at velocity w and make four important observations:
- The jogger is always able to run from the rear of the bus to its front, and vice versa.
- When the jogger has reached the front of the bus, she has traveled the length x’.
- When the jogger has traveled one–half the round–trip distance, she has reached the front of the bus.
- The jogger moves at velocity w.
The principle of relativity says that what is observed when the bus is stationary must be what is observed when the bus is in motion. The principle of the constant velocity of light essentially says that the woman always moves with respect to the stationary system and both observers view her as moving at the same velocity. Remember, Einstein believes that both postulates must always apply. We must explore the mathematical and conceptual adjustments Einstein makes to remain aligned with this belief.
Let’s examine what happens when the bus is placed into motion at velocity v.
Observation 1 – The jogger is always able to run from the rear of the bus to its front, and vice versa
The principle of relativity requires that the jogger must always be able to run from the rear of the bus to its front, since she is able to always do so when the bus is stationary. Notice that the jogger can only run from the rear of the bus to its front when the velocity of the bus is less than the jogger’s velocity. In mathematical terms, v < w must always be true. This restriction is imposed by Einstein’s postulates, where if this restriction were not present we could have a case where jogger would never reach the front of the bus, violating the principle of relativity. The restriction imposed by this postulate disagrees with reality, where we know that the velocity of a bus in not limited by how fast a person can run. None–the–less, this restriction is required to satisfy both postulates.
When discussing the electromagnetic force, the bus is generalized as a moving system and the jogger is replaced by a ray of light traveling at c. This changes the mathematical relationship to v < c, and is why relativity theory says that the velocity of the moving system has to be less than the speed of light. It is important to remember that this is an artificial constraint that is specifically required to satisfy both of Einstein’s postulates, which we have already shown are incompatible.
Observation 2 – When the jogger has reached the front of the bus, she has traveled length x’
From the perspective of the moving observer, the principle of relativity requires that that jogger travel length x’ to reach the front of bus. As illustrated in Figure B, above, the moving observer uses the ruler on the bottom of the bus to conclude that the jogger has moved from the white triangle (when she began running, as shown in Figure A, above) to the white circle. The distance from the white triangle to the white circle, called the segment length, represents the length of the bus, x’. The stationary observer uses the street as the ruler and measures the forward intercept length as the distance the jogger runs from the black triangle (when she began running, as shown in Figure A, above) to the black circle.
While this explanation seems simple enough, there’s one problem: If the jogger has reached the halfway point from the perspective of the moving system, then she must also be at the halfway point with respect to the stationary system. But this isn’t the case. From the perspective of the moving observer, the jogger has run the length of the bus, x’, which is one–half the total distance from his perspective. However, with respect to the stationary observer, the jogger has run the forward intercept length, which is longer than one–half her round–trip distance. This is not consistent and would violate the principle of relativity, which brings us to the third observation.
Observation 3 – When the jogger has traveled one–half the round–trip distance, she has reached the front of the bus
The principle of relativity requires that what occurs when the system is in motion be the same as when the system is stationary. Observation 2 placed the jogger at the front of the bus. Observation 3 says that when the jogger has traveled length x’ from the perspective of the moving system, that she must be:
- at the halfway point from the perspective of the moving observer, and
- at the halfway point with respect to the stationary observer.
We know from earlier tutorials that one–half of the jogger’s total distance, with respect to the stationary observer, is the average intercept length. To align the diagram with this adjustment, relativity requires that we reposition the jogger to the average intercept length rather than at the forward intercept length. As shown in Figure C, we position the jogger at the average intercept length and position the front of the bus at x”. Neither the bus nor the jogger are positioned at the forward intercept.
This conceptual repositioning solves one problem, but creates a new one. Notice that when the jogger has traveled the average intercept length, she has not yet reached the front of the bus. So in actuality, she has not traveled the length x’ from the perspective of the moving observer. This problem is overcome by repositioning the front of the bus to also correspond to the average intercept length, as show in Figure D.
Although consistent with Einstein’s postulates, both repositioning ignore two important facts. First, the jogger does not arrive at the front of the bus until she has traveled the forward intercept length in the stationary system. Second, it ignores that the front of the bus is actually further on the x axis than Einstein states. The bus is actually at x”, but Einstein has repositioned it to correspond with the average intercept length.
Conceptually, these adjustments mean that the jogger has reached the front of the bus when she has reached the average intercept length from the perspective of the moving observer. However, we know that the jogger does not reach the front of the bus until she has traveled the forward intercept length with respect to the stationary observer. Once again we have a problem where one observer sees something that differs from what the other sees. How can one observer see something that is symmetrical and the other something that is asymmetrical? Einstein says this is possible and gives it a name: Simultaneity.
Mathematically, we can’t simply reposition things and say that’s how the world operates. These adjustments have to be proven, which is why Einstein needs the spherical wave proof. Although we have already shown that the proof fails, we continue to proceed with the understanding that Einstein believes his proof worked. This means he must explain the mathematical relationship between the length the moving observer measures, x’, and the length the stationary observer measures, the average intercept length. This relationship is defined by the average intercept length equation:
ξ = x’ / (1 – v2 / w2 )
or, when specifically discussing a ray of light traveling through an electromagnetic vacuum:
ξ = x’ / (1 – v2 / c2 )
The average intercept length will always be greater than the segment length x’ when the moving system is in motion. The relationship where the length of the bus (eg, the original segment length) x’ is always less than the average intercept length is what Einstein refers to as length contraction.
Observation 4 – The jogger moves at velocity w
When the bus is stationary, the moving observer determines that the jogger runs at velocity w. So to remain aligned with both postulates, he must conclude that the jogger is still running at velocity w when the bus is moving at velocity v. Scientists who argue against relativity theory often correctly state that the jogger is moving at the apparent velocity w – v. While true, the use of this expression as the velocity of the jogger would violate the first postulate. To remain internally consistent with the use of relative measurements and align with his postulates, Einstein accepts that both observers believe that the jogger is moving at velocity w. In such a case, the moving observer would need to treat v as if it were zero. In fact, this is why many scientist argue that experiments like the Michelson–Morley experiment must produce a 0km/s result. Regardless of whether you believe the assumption is correct, you must accept it as Einstein’s approach.
If, from the perspective of the moving observer, the jogger has traveled a distance of x’ and is moving at velocity w, then the amount of time required for her to run this distance is simply length divided by velocity. Using variables and expressions that Einstein’s attributes to the moving system:
τ = ξ / w
τ = x’ / (1 – v2 / w2 ) / w
As discussed above, when discussing the electromagnetic force w is replaced by c in the equations. When the bus is moving at velocity v, the average intercept time will always be greater than the amount of time the jogger needs to run the segment length x’ (aka, the segment time). This relationship where the average intercept time is greater than the segment time is called: time dilation.
It is interesting to consider that we do not use time dilation or length contraction to explain the forward or reflected Doppler shifts (eg, forward and reflected intercepts in Modern Mechanics). If we don’t use Einstein’s concepts in explaining those terms, then we can reasonably argue that those same terms are not required to explain the average of those equations (eg, the average intercept length ξ or the average intercept time τ).
Einstein was extremely thoughtful in the development of his work. It is apparent that he accounts for situations that would violate his postulates, which he addresses using concepts and constraints. Conceptually, his theory requires length contraction, time dilation, and simultaneity. You cannot have these terms without relativity theory or vice versa. As a constraint, Einstein’s maximum velocity for a moving system is needed to ensure that everything that can be observed when a system is stationary can also be observed when it is in motion. Unfortunately, Einstein did not fully understand the equations he had found or how they are generalized.
As a recap, the spherical wave proof failed; which means that Einstein was unsuccessful in associating his postulates with one another. So the terms and restrictions associated with Einstein’s work do not apply. Said simply, explaining motion does not require time dilation, length contraction, or simultaneity. In addition, the velocity of a moving system is not theoretically limited. Modern Mechanics provides an intuitive framework for explaining motion that is built upon a well–understood mathematical foundation called geometric transformations. Not only does Modern Mechanics provide equations that perform better than relativity’s equations, it opens the door to the possibility of faster than light interaction and motion. This provides avenues for faster than light communication and travel, as well as possible theoretical explanations for observations like quantum mechanics’ entanglement. Of course, traveling faster than the speed of light would certainly require new engineering and scientific breakthroughs.
Note: This Tutorial uses Einstein’s equations prior to “substituting x’ with it’s value” in §3 of his 1905 paper. This simplifies our analysis, because it keeps the emphasis on length x’. In addition, our analysis is further simplified by performing the analysis prior to Einstein’s unannounced adjustment where he drops a β term which, as discussed in Tutorial twelve, introduces error not present in the Modern Mechanics equations.

If you frequently wake up two or three hours before your alarm, know that you are not alone. Many people, doesn’t know connection between pregnancy and sleep. Also, regardless of their life stage or health, experience this common problem of waking up too early. This sleep disturbance can be distressing and lead to exhaustion. The good news is that there are various treatment options and lifestyle changes available to help you achieve a full night’s sleep once again. Many factors are affected the sleep pattern, Here we explore about Pregnancy and Sleep connection like early wake-up or sleep disturbance.
Why am I wake-up early during pregnancy?
The study reveals that disturbing the altered daily timing during pregnancy may pose a risk to the pregnancy. This finding marks a significant initial advancement in comprehending the dynamics of term pregnancy, potentially offering insights to intervene and prevent preterm birth in specific populations.
Nationally, one in 10 babies is born prematurely, before 37 weeks. Previous research has linked shift work and disruptions in regular sleep-wake schedules with preterm birth and other adverse reproductive outcomes. However, until now, there has been limited understanding of circadian timing during pregnancy.
The Effects of Pregnancy on Sleep
Pregnancy significantly affects sleep in various ways, including changes in sleep quality, quantity, and overall sleep patterns. For individuals with pre-existing sleep disorders, these conditions may worsen during pregnancy.
Additionally, many new sleep problems can arise for the first time during pregnancy. While some of these issues may begin shortly after conception, they often intensify in frequency and duration as the pregnancy advances.
During the third trimester, almost all women experience an increase in nighttime awakenings. Physical discomfort, psychological adjustments, and hormonal fluctuations collectively impact sleep, resulting in excessive daytime sleepiness and fatigue.. The combination of these factors can contribute to sleep disturbances throughout the pregnancy.
Sleep Disturbance in some specific time during pregnancy?
During pregnancy, especially in the first and third trimesters, sleep disturbances are common. In the early stages, your body undergoes rapid physical and hormonal changes, leading to issues such as heartburn, morning sickness (nausea and vomiting that can occur during the day or at night), leg cramps, shortness of breath, abdominal discomfort, breast tenderness, vivid dreams, back pain, and frequent nighttime urination.
Already Sleeping Pattern Not Set?
If you have already Sleep difficulties? it can worsen during pregnancy, and new challenges may arise with each phase of the journey. It is essential to understand how hormones play a role in sleep during pregnancy, explore potential solutions to address sleep problems, and discover the best positions to alleviate back pain and insomnia. By reviewing these aspects, you can optimize your sleep quality throughout your pregnancy and find ways to manage and overcome sleep-related challenges that may arise.
How Your Pregnancy Hormones affect your Sleep
Hormonal changes play a significant role in how pregnancy affects sleep. These changes are a natural part of being pregnant and can impact various aspects of the body and brain. Here’s how hormones can affect sleep during pregnancy:
- The hormone progesterone relaxes smooth muscles in the body, causing frequent urination, heartburn, and nasal congestion. These issues can disrupt sleep patterns. It also reduces wakefulness during the night and decreases the amount of REM sleep, the phase characterized by vivid dreaming. Progesterone can also shorten the time it takes to fall asleep.
- Another important hormone in pregnancy, estrogen can cause blood vessels to expand (vasodilation). This may result in swelling or edema in the feet and legs and increased congestion in the nose, which can interfere with breathing during sleep. Like progesterone, estrogen can also reduce the amount of REM sleep.
- Melatonin levels tend to be higher during pregnancy, which may impact sleep patterns. Prolactin, another hormone, can increase slow-wave sleep, which is the deep and restorative phase of sleep.
It’s important to note that these hormonal changes can vary from person to person, and each woman’s experience of sleep during pregnancy may be unique.
Studies have uncovered patterns of pregnancy and sleep
Research studies have revealed significant changes in sleep patterns throughout pregnancy. These changes have been observed through polysomnography, a sleep study that monitors various sleep characteristics. Here’s a breakdown of how sleep changes in each trimester:
- In the first trimester (first 12 weeks) of pregnancy, total sleep time tends to increase. This phase is characterized by longer sleep periods at night and a tendency for more frequent daytime napping.. However, sleep efficiency decreases, characterized by more frequent awakenings during the night. Deep or slow-wave sleep also decreases, leading to complaints of poor sleep quality.
- Second Trimester (Weeks 13 to Weeks 28): Sleep tends to improve during the second trimester. Sleep efficiency increases, and less time is spent awake after initially falling asleep at night. However, as the second trimester comes to an end, the number of awakenings during the night starts to rise again.
- Third Trimester (Weeks 29 to Term): In the final trimester, pregnant women experience more nighttime awakenings and spend more time awake during the night. Daytime napping becomes more frequent, leading to reduced sleep efficiency. Additionally, sleep becomes lighter, with more frequent occurrences of stage 1 or 2 sleep.
Possible Sleep Problems During Pregnancy
Pregnancy can give rise to various sleep problems and symptoms. Alongside the changes in sleep patterns and stages mentioned earlier, certain sleep disorders and symptoms may manifest during pregnancy. These can be categorized by trimester and may culminate in the effects of labor and delivery. Here’s an overview:
- Increased daytime sleepiness and fatigue
- Insomnia or difficulty falling asleep
- Frequent urination disrupting sleep
- Nausea and vomiting affecting sleep quality
- Restless legs syndrome (RLS) or uncomfortable sensations in the legs
- Leg cramps during sleep
- Increased snoring or development of sleep apnea
- Heartburn or acid reflux causing nighttime awakenings
- More frequent nighttime awakenings
- Difficulty finding a comfortable sleeping position due to a growing belly
- Pregnancy often leads to an increased need to urinate during the night
- Shortness of breath and difficulty breathing while lying down.
Labor and Delivery:
- Disrupted sleep due to discomfort and contractions
- Anxiety and anticipation affecting sleep quality
It’s important to remember that not all pregnant individuals will experience these sleep problems, and the severity can vary. If you have concerns about your sleep during pregnancy, it’s advisable to consult with your healthcare provider for guidance and support.
When The Sleep Disruptions May Improve During Pregnancy?
- Although some pregnancy-related sleep disruptions may improve during the second trimester, they often return during the third. As your baby grows larger and your body further adjusts to accommodate them, sleep can become difficult once again. In the third trimester, sinus congestion, leg cramps, hip pain, the urge to urinate, and other discomforts can prevent you from getting a restful night’s sleep.
Strategies to Improve : Pregnancy and Sleep
During pregnancy, it is common for women to experience changes in their sleep patterns. If you’re waking up early and having trouble getting enough sleep, there are several strategies you can try to improve your sleep during pregnancy:
1. Establish a regular sleep routine:
- Go to bed and wake up at the same time each day, including weekends. This helps regulate your body’s internal clock and promotes better sleep.
2. Create a comfortable sleep environment during pregnancy:
- Ensure that your bedroom is cool, dark, and quiet. Use curtains or an eye mask to block out any excess light, and consider using earplugs or a white noise machine to drown out any disturbing noises.
3. Practice relaxation techniques for sleep during pregnancy
- Before going to bed, engage in activities that help you relax, such as taking a warm bath, practicing deep breathing exercises, or listening to calming music. This can help prepare your body for sleep.
4. Support your body with pillows:
- Use pregnancy pillows or regular pillows to support your body and find a comfortable sleeping position. Experiment with different positions, such as sleeping on your side with a pillow between your knees, to relieve any discomfort and promote better sleep.
5. Limit fluid intake before bed:
- Reduce your intake of fluids a few hours before bedtime to minimize the need for frequent trips to the bathroom during the night.
6. Watch your caffeine intake:
- Avoid or limit caffeine, especially in the afternoon and evening. Caffeine can interfere with sleep and increase the frequency of waking up.
7. Stay active during the day:
- Engage in regular physical activity during the day, but avoid exercising close to bedtime. Exercise can help improve sleep quality and reduce restlessness.
8. Manage stress and anxiety:
- Pregnancy can bring about various emotions and concerns. Practice relaxation techniques, such as meditation or prenatal yoga, to help reduce stress and anxiety that might interfere with sleep.
9. Avoid stimulating activities before bed:
- Limit exposure to electronic screens (e.g., smartphones, tablets, TVs) at least an hour before bedtime, as the blue light emitted by these devices can interfere with sleep.
10. Talk to your healthcare provider:
- If your sleep problems persist or worsen, consult your healthcare provider. They can provide personalized advice and may recommend safe sleep aids or other interventions if necessary.
Sleep undergoes significant changes throughout the major trimesters of pregnancy. Hormonal fluctuations impact sleep structure, and physical discomforts that often accompany pregnancy can lead to disrupted sleep. The good news is that many of these sleep difficulties tend to resolve after childbirth.
If you are experiencing sleep difficulties during pregnancy, it’s crucial to talk to your obstetrician about it. They can provide guidance and support, and if necessary, they may refer you to a board-certified sleep physician who can discuss treatment options for sleep disorders like sleep apnea, insomnia, or restless legs syndrome. Don’t hesitate to seek help and support to improve your sleep during this special time.
Remember, every pregnancy is different, and what works for one person may not work for another. It’s essential to listen to your body, prioritize self-care, and consult your healthcare provider for guidance specific to your situation. | <urn:uuid:51f1ec2a-41b5-4dbc-984c-71d84c5aa1a5> | CC-MAIN-2024-51 | https://themomnbaby.com/pregnancy-and-sleep/ | 2024-12-01T19:58:46Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066036672.6/warc/CC-MAIN-20241201192453-20241201222453-00100.warc.gz | en | 0.940361 | 2,186 | 2.546875 | 3 |

To begin with, you should know that kittens are born with blue eyes . If you've ever had it, you may have noticed it. They may stay that way, but more often than not, their eye color begins to change as they grow and production of the pigment melanin occurs.
Adult cats with blue eyes are not very common. When this happens, it is a result of their genetics. Pigment production in their irises does not take place, and when light reflects off the rounded surface of their eyes, they appear blue. Blue-eyed cats are very diverse in personality and activity level. Some breeds are closely related, while others are more distinct.
Genes that limit coloring in cats result in blue eyes. Breeds of so-called “pointed” cats (i.e. those with specific colored spots called “points” in cats), which have a lighter body and darker extremities (like the Siamese ), always have blue eyes.
Additionally, cats that have the dominant white gene can sometimes, but not always, have blue eyes. White cats with blue eyes are also genetically predisposed to deafness.
If you want a purebred cat with blue eyes, look for breeds with seal-point coats, which are genetically linked to blue eyes. Blue-eyed cat breeds include Siamese, Balinese, Himalayan, Persian, Burmese, and Javanese.
Ragdolls are known for their sparkling blue eyes, but not all Ragdolls have this color. There is also the very rare Ojos Azules breed, which can produce cats with dark coats and blue eyes. According to experts, the blue eyes of these breeds are not linked to deafness.
It's a different story when it comes to blue-eyed white cats - about 60 percent of predominantly white kittens - who get their color from mutations in a gene called KIT. In these cats, blue eyes result from a cellular problem: their irises have fewer melanocytes (the cells that produce melanin pigments).
These same cells create skin pigment and play a role in the functioning of the inner ear. Therefore, cats with fewer melanocytes – white cats with blue eyes – may not have enough of these cells for their hearing to work properly.
White cats have a genetic makeup similar to that of albino humans, who lack pigment; this gives them certain vulnerabilities, such as sensitivity to UV rays.
It is estimated that 40% of white cats with blue eyes are deaf , which is high. But look at it this way: if 40% of these cats are deaf, that means the majority (60%) can hear.
Some cats have mixed eye colors, such as one blue eye and one green eye. In this case, hearing loss may occur in only one ear, especially on the side of the face where the blue eye is located.
Like some human babies, all kittens are born with blue eyes which may change color later. The shade begins to change to the kitten's true eye color around 6 or 7 weeks of age. Iris melanocytes – the pigment that gives the cat's eye its adult color – develop once the eye is sufficiently mature.
If you want to know if a blue-eyed cat is deaf , stand a few feet behind it and clap your hands or make another loud noise. If your cat reacts and looks towards you, he is probably not deaf , at least in both ears. Cats sense non-auditory vibrations very well, however, so position yourself on the opposite side of the room to allow enough space.
If you're still unsure if a white cat with blue eyes is deaf (or curious about a cat's hearing problems), take him to your veterinarian for more specific testing.
Here are 10 breeds of cats that always or sometimes have blue eyes as adults:
Weight: 3 to 5 kg
Size: about 45cm
Physical Characteristics: Slender body with a long tail and pointed ears; the coat is long and silky, creamy white with pointed colors (the name given to color spots in cats) around the face, ears, tail and legs.
The Balinese is a breed of cat that will always have deep blue eyes and this is perhaps one of the characteristics that makes them particularly bewitching. The long coat of these strikingly beautiful felines is the result of a spontaneous genetic mutation in purebred Siamese cats. These medium-sized cats don't just have a pretty face. They are also known for being intelligent, curious, playful and affectionate. Balinese cats can make excellent pets.
Weight: 4 to 6 kg
Size: 38 to 45 cm
Physical Characteristics: Long, silky hair and pointed markings (the name given to color spots in cats); the coat comes in seal, blue, chocolate, red, cream and tortoiseshell colors with pointed or lynx patterns.
Among blue-eyed cats, the Burmese is another particularly attractive cat breed. This long-haired cat comes in six different colors, but he always has white mittens on his paws. The exact history of the breed is not clearly known, but it may have emerged after cats imported from Burma were crossed with Siamese cats in France in the 1920s. Burmese are gentle, playful and affectionate. Although still a particularly “vocal” breed, their meows are not as loud as those of their close Balinese and Siamese relatives.
Weight: 3 to 6 kg
Physical characteristics: Broad chest, round abdomen and musculature; it can often appear larger than it actually is; its coat is cream, gray, blue, and chocolate colored with pointed markings.
The Himalayan Spotted was created by crossing Siamese and Persian cats. Not all organizations recognize the breed as distinct from Persian. The Himalayan's eyes are always a bright blue, and its coat, which comes in a variety of shades, is long and dense. Himalayans are generally incredibly affectionate and playful. However, they can get into mischief if they don't get enough love and attention. Due to its thick coat, this breed also requires extensive grooming.
Size: 35 to 45 cm
Physical Characteristics: Robust construction; “crushed” face; round, lively eyes; long, silky coat in solid, bi-color, tabby, calico and other color and pattern variations.
With their soft, silky coats, distinctive squashed faces, and gentle personalities, Persians are one of the most popular and recognizable cat breeds. White Persians often have blue eyes. Persians are known for being undemanding, calm and affectionate. They love nothing better than to curl up on their owner's lap to receive affection. However, you will need to prepare for a very demanding grooming regime due to its lush coat.
Weight: 4 to 5 kg
Size: 20 to 25 cm
Physical Characteristics: Smooth body, almond-shaped blue eyes, large ears, wedge-shaped head.
The popular Siamese has charmed cat lovers around the world for decades. With her almond-shaped blue eyes, sharp color, elegant physique and sociable nature, isn't that a surprise? Meezers, as they are affectionately called, are very intelligent and curious. They also like to be the center of attention and won't hesitate to tell you when they need more cuddles. With a wide range of vocalizations and a loud meow, they don't like to be ignored.
Weight: 3 to 7 kg
Size: About 30 cm
Physical Characteristics: Generally short-haired; wide variety of colors except white, although white spots are accepted.
The Ojos Azules (the Spanish translation for "blue eyes") is a rare cat breed , and its breed standard is still being developed. However, its eyes are still an unusually deep shade of blue, although it is not a sharp or solid white color. The breed's origins date back to 1984, when a tortoiseshell cat from a feral colony in New Mexico produced a litter with intense blue eyes like hers. These cats went on to produce litters with a variety of markings and perhaps the deepest blue eyes ever seen in a cat breed.
Weight: 4 to 9 kg
Size: 23 to 28 cm
Physical Characteristics: Large semi-long coat, blue eyes, variable coloring.
It's hard to find a more laid-back cat than the ragdoll. And it's easy to be seduced by these charming cats and their big blue eyes. Their friendly and intelligent nature is often compared to that of dogs. It's not uncommon for ragdolls to do tricks to get treats. To prevent these energetic and social cats from becoming bored, it is important that they have plenty of company during the day and enrichment in the home.
Physical characteristics: Light body with darker spots on the ears, face, legs and tail; breast generally white; short to medium long hair.
The Snowshoe cat was created by crossing Siamese cats with the American shorthair. Another pointed breed, these cats always have blue eyes. They get their name from their white muffled legs that appear to have been soaked in snow. Not surprisingly, snowshoes share many traits with their Siamese relatives. They want to participate in everything. They are intelligent, loud and easily bored.
Physical characteristics: Basic colors are platinum, champagne, blue and natural; the patterns are solid, mink and dot.
The Tonkinese is a cross between the Siamese and the Burmese. It has a lovely soft, pointed color, and its eyes can be blue, aqua, or yellow-green. These cats tend to be very affectionate and very playful. They are not as talkative as the Siamese, but they express their feelings.
Weight: 2 to 4 kg
Physical Characteristics: Long, silky hair, white with various color combinations.
Blue is the most common eye color of the exquisite Turkish Angora , but its eyes can also be green, golden, amber, and even bi-colored. This cat often has a shimmering white coat and a long body. He is quite affectionate and friendly and is best suited to a home where he will have company for much of the day.

Good work design can help us achieve safe outcomes by designing safety into work processes and the design of products. Adding safety as an afterthought is almost always less effective and costs more over the lifecycle of the process or product.
The Australian Work Health and Safety Strategy 2012-2022 is underpinned by the principle that well-designed healthy and safe work will allow workers to have more productive lives. This can be more efficiently achieved if hazards and risks are eliminated through good design.
The Ten Principles of Good Work Design
This handbook contains ten principles that demonstrate how to achieve the good design of work and work processes. Each is general in nature so they can be successfully applied to any workplace, business, or industry.
The ten principles for good work design are structured into three sections:
- Why good work design is important;
- What should be considered in good work design; and
- How good work is designed.
These principles are shown in the diagram in Figure 1.
This handbook complements a range of existing resources available to businesses and work health and safety professionals including guidance for the safe design of plant and structures see the Safe Work Australia Website.
Scope of the Handbook
This handbook provides information on how to apply good work design principles to work and work processes to protect workers and others who may be affected by the work.
It describes how design can be used to set up the workplace, working environment, and work tasks to protect the health and safety of workers, taking into account their range of abilities and vulnerabilities, so far as reasonably practicable.
The handbook does not aim to provide advice on managing situations where individual workers may have special requirements such as those with a disability or on a return to work program following an injury or illness.
Who Should Use this Handbook?
This handbook should be used by those with a role in designing work and work processes, including:
- Persons conducting a business or undertaking (PCBUs) with a primary duty of care under the model Work Health and Safety (WHS) laws.
- PCBUs who have specific design duties relating to the design of plant, substances, and structures including the buildings in which people work.
- People responsible for designing organizational structures, staffing rosters, and systems of work.
- Professionals who provide expert advice to organizations on work health and safety matters.
Good work design optimizes work health and safety, human performance, job satisfaction, and business success.
Information: Experts who provide advice on the design of work may include: engineers, architects, ergonomists, information, and computer technology professionals, occupational hygienists, organizational psychologists, human resource professionals, occupational therapists, and physiotherapists.
What is ‘Good Work’?
‘Good work’ is healthy and safe work where the hazards and risks are eliminated or minimized so far as is reasonably practicable. Good work is also where the work design optimizes human performance, job satisfaction, and productivity.
Good work contains positive work elements that can:
- protect workers from harm to their health, safety, and welfare;
- improve worker health and wellbeing; and
- improve business success through higher worker productivity.
What is Good Work Design?
The most effective design process begins at the earliest opportunity during the conceptual and planning phases. At this early stage there is the greatest chance of finding ways to design-out hazards, incorporate effective risk control measures, and design-in efficiencies.
Effective design of good work considers:
- how work is performed, including the physical, mental and emotional demands of the tasks and activities
- the task duration, frequency, complexity, and
- the context and systems of work.
The physical working environment:
- the plant, equipment, materials, and substances used, and
- the vehicles, buildings, and structures that are workplaces.
- physical, emotional, and mental capacities and needs.
Effective design of good work can radically transform the workplace in ways that benefit the business, workers, clients, and others in the supply chain.
Failure to consider how work is designed can result in poor risk management and lost opportunities to innovate and improve the effectiveness and efficiency of work.
The principles for good work design support duty holders to meet their obligations under the WHS laws and also help them to achieve better business practice generally.
For the purposes of this handbook, a work designer is anyone who makes decisions about the design or redesign of work. This may be driven by the desire to improve productivity as well as the health and safety of people who will be doing the work
The WHY Principles
Why is good work design important?
Principle 1: Good work design gives the highest level of protection so far as is reasonably practicable
- All workers have a right to the highest practicable level of protection against harm to their health, safety, and welfare.
- The primary purpose of the WHS laws is to protect persons from work-related harm so far as is reasonably practicable.
- Harm relates to the possibility that death, injury, illness, or disease may result from exposure to a hazard in the short or long term.
- Eliminating or minimizing hazards at the source before risks are introduced in the workplace is a very effective way of providing the highest level of protection.
Principle 1 refers to the legal duties under the WHS laws. These laws provide the framework to protect the health, safety, and welfare of workers and others who might be affected by the work. During the work design, process workers and others should be given the highest level of protection against harm that is reasonably practicable.
Prevention of workplace injury and illness
Well-designed work can prevent work-related deaths, injuries, and illnesses. The potential risk of harm from hazards in a workplace should be eliminated through good work design.
Only if that is not reasonably practicable, then the design process should minimize hazards and risks through the selection and use of appropriate control measures.
New hazards may inadvertently be created when changing work processes. If the good work design principles are systematically applied, potential hazards and risks arising from these changes can be eliminated or minimized.
Information: Reducing the speed of an inappropriately fast process line will not only reduce production errors, but can also diminish the likelihood of a musculoskeletal injury and mental stress.
Principle 2: Good work design enhances health and wellbeing
- Health is a “state of complete physical, mental, and social wellbeing, not merely the absence of disease or infirmity” (World Health Organisation).
- Designing good work can help improve health over the longer term by improving workers’ musculoskeletal condition, cardiovascular functioning, and mental health.
- Good work design optimizes worker function and improves participation enabling workers to have more productive working lives.
An effective design aims to prevent harm, but it can also positively enhance the health and wellbeing of workers, for example, satisfying work and positive social interactions can help improve people’s physical and mental health.
As a general guide, the healthiest workers have been found to be three times more productive than the least healthy. It, therefore, makes good business sense for work design to support people’s health and wellbeing.
Information: Recent research has shown long periods of sitting (regardless of exercise regime) can lead to an increased risk of preventable musculoskeletal disorders and chronic diseases such as diabetes. In an office environment, prolonged sitting can be reduced by allowing people to alternate between sitting or standing whilst working.
Principle 3: Good work design enhances business success and productivity
- Good work design prevents deaths, injuries, and illnesses and their associated costs, improves worker motivation and engagement, and in the long-term improves business productivity.
- Well-designed work fosters innovation, quality, and efficiencies through effective and continuous improvement.
- Well-designed work helps manage risks to business sustainability and profitability by making work processes more efficient and effective and by improving product and service quality.
Cost savings and productivity improvements
Designing-out problems before they arise is generally cheaper than making changes after the resulting event, for example by avoiding expensive retrofitting of workplace controls.
Good work design can have direct and tangible cost savings by decreasing disruption to work processes and the costs from workplace injuries and illnesses.
Good work design can also lead to productivity improvements and business sustainability by:
- allowing organizations to adjust to changing business needs and streamline work processes by reducing wastage, training, and supervision costs
- improving opportunities for creativity and innovation to solve production issues, reduce errors and improve service and product quality, and
- making better use of workers’ skills resulting in more engaged and motivated staff willing to contribute greater additional effort.
The WHAT Principles
What should be considered by those with design responsibilities?
Principle 4: Good work design addresses physical, biomechanical, cognitive, and psychosocial characteristics of work, together with the needs and capabilities of the people involved
- Good work design addresses the different hazards associated with work e.g. chemical, biological, and plant hazards, hazardous manual tasks, and aspects of work that can impact mental health.
- Work characteristics should be systematically considered when work is designed, redesigned or the hazards and risks are assessed.
- These work characteristics should be considered in combination and one characteristic should not be considered in isolation.
- Good work design creates jobs and tasks that accommodate the abilities and vulnerabilities of workers so far as reasonably practicable.
All tasks have key characteristics with associated hazards and risks, as shown in Figure 2 below:
Figure 2 – Key characteristics of work.
Hazards and risks associated with tasks are identified and controlled during good work design processes and they should be considered in combination with all hazards and risks in the workplace. This highlights that it is the combination that is important for good work design.
Workers can also be exposed to a number of different hazards from a single task. For example, meat boning is a common task in a meat-processing workplace. This task has a range of potential hazards and risks that need to be managed, e.g. physical, chemical, biological, biomechanical, and psychosocial. Good work design means the hazards and risks arising from this task are considered both individually and collectively to ensure the best control solutions are identified and applied.
Good work design can prevent unintended consequences which might arise if task control measures are implemented in isolation from other job considerations. For example, automation of a process may improve production speed and reduce musculoskeletal injuries but increase the risk of hearing loss if effective noise control measures are not also considered.
Workers have different needs and capabilities; good work design takes these into account. This includes designing to accommodate them given the normal range of human cognitive, biomechanical and psychological characteristics of the work.
Information: The Australian workforce is changing. It is typically older with higher educational levels, more inclusive of people with disabilities, and more socially and ethnically diverse. Good work design accommodates and embraces worker diversity. It will also help a business become an employer of choice, able to attract and retain an experienced workforce.
Principle 5: Good work design considers the business needs, context, and work environment.
- Good work design is ‘fit for purpose’ and should reflect the needs of the organization including owners, managers, workers, and clients.
- Every workplace is different so approaches need to be context-specific. What is good for one situation cannot be assumed to be good for another, so off-the-shelf solutions may not always suit every situation.
- The work environment is broad and includes: the physical structures, plant and technology, work layout, organizational design and culture, human resource systems, work health and safety processes, and information/control systems.
The business organizational structure and culture, decision-making processes, work environment, and how resources and people are allocated to the work will, directly and indirectly, impact on work design and how well and safely the work is done.
The work environment includes the physical structures, plant, and technology. Planning for relocations, refurbishments, or when introducing new engineering systems are ideal opportunities for businesses to improve their work designs and avoid foreseeable risks.
These are amongst the most common work changes a business undertakes yet good design during these processes is often quite poorly considered and implemented. An effective design following the processes described in this handbook can yield significant business benefits.
Information: Off-the-shelf solutions can be explored for some common tasks, however usually design solutions need to be tailored to suit a particular workplace.
Good work design is most effective when it addresses the specific business needs of the individual workplace or business. Typically work design solutions will differ between small and large businesses.
However, all businesses must eliminate or minimize their work health and safety risks so far as reasonably practicable. The specific strategies and controls will vary depending on the circumstances.
The table on the next page demonstrates how to step through the good work design process for small and large businesses.
Good design steps | In a large business that is downsizing | In a small business that is undergoing a refit |
Management commitment | Senior management make their commitment to good work design explicit ahead of downsizing and may hire external expertise. | The owner tells workers about their commitment to designing-out hazards during the upcoming refit of the store layout to help improve safety and efficiency. |
Consult | The consequences of downsizing and how these can be managed are discussed in senior management and WHS committee meetings with appropriate representation from affected work areas. | The owner holds meetings with their workers to identify possible issues ahead of the refit. |
Identify | A comprehensive workload audit is undertaken to clarify opportunities for improvements. | The owner discusses the proposed refit with the architect and builder and gets ideas for dealing with issues raised by workers. |
Assess | A cost-benefit analysis is undertaken to assess the work design options to manage the downsizing. | The owner, architect, and builder jointly discuss the proposed refit and any worker issues directly with workers. |
Control | A change management plan is developed and implemented to appropriately structure teams and improve systems of work. Training is provided to support the new work arrangements. | The building refit occurs. Workers are given training and supervision to become familiar with a new layout and safe equipment use. |
Review | The work redesign process is reviewed against the project aims by senior managers. | The owner checks with the workers that the refit has improved working conditions and efficiency and there are no new issues. |
Improve | Following consultation, refinement of the redesign is undertaken if required. | Minor adjustments to the fit-out are made if required. |
Principle 6: Good work design is applied along the supply chain and across the operational lifecycle.
- Good work design should be applied along the supply chain in the design, manufacture, distribution, use and disposal of goods and the supply of services.
- Work design is relevant at all stages of the operational life cycle, from start-up, routine operations, maintenance, downsizing and cessation of business operations.
- New initiatives, technologies, and changes in organizations have implications for work design and should be considered.
Information: Supply chains are often made up of complex commercial or business relationships and contracts designed to provide goods or services. These are often designed to provide goods or services to a large, dominant business in a supply chain. The human and operational costs of poor design by a business can be passed up or down the supply chain.
Businesses in the supply chain can have significant influence over their supply chain partners’ work health and safety through the way they design the work.
Businesses may create risks and so they need to be active in working with their supply chains and networks to solve work health and safety problems and share practical solutions for example, for common design and manufacturing problems.
Health and safety risks can be created at any point along the supply chain, for example, loading and unloading causing time pressure for the transport business.
There can be a flow-on effect where the health and safety and business ‘costs’ of poor design may be passed down the supply chain. These can be prevented if businesses work with their supply chain partners to understand how contractual arrangements affect health and safety.
Procurement and contract officers can also positively influence their own organization and others’ work health and safety throughout the supply chain through the good design of contracts.
When designing contractual arrangements businesses could consider ways to support good work design safety outcomes by:
- setting clear health and safety expectations for their supply chain partners, for example through the use of codes of conduct or quality standards
- conducting walk-through inspections, monitoring, and comprehensive auditing of supply chain partners to check adherence to these codes and standards
- building the capability of their own procurement staff to understand the impacts of contractual arrangements on their suppliers, and
- consulting with their supply chain partners on the design of good work practices.
Information: The road transport industry is an example of the application of how this principle can help improve drivers’ health and safety and address issues arising from supply chain arrangements. For example, the National Heavy Vehicle Laws ‘chain of responsibility’ requires all participants in the road transport supply chain to take responsibility for driver work health and safety. Contracts must be designed to allow drivers to work reasonable hours, take sufficient breaks from driving and not have to speed to meet deadlines.
The design of products will strongly impact both health and safety and business productivity throughout their lifecycles. At every stage, there are opportunities to eliminate or minimize risks through good work design. The common product lifecycle stages are illustrated in Figure 3 below.
Information: For more information on the design of structures and plant see ‘Safe design of structures’ and Managing the risks of plant in the workplace and other design guidance on the Safe Work Australia website.
The good work design principles are also relevant at all stages of the business life cycle. Some of these stages present particularly serious and complex work health and safety challenges such as during the rapid expansion or contraction of businesses. Systematic application of good work design principles during these times can achieve positive work health and safety outcomes.
New technology is often a key driver of change in work design. It has the potential to improve the quality of outputs, efficiency, and safety of workers, however introducing new technology could also introduce new hazards and unforeseen risks. Good work design considers the impact of the new initiatives and technologies before they are introduced into the workplace and monitors their impact over time.
Information: When designing a machine for safe use, how the maintenance will be undertaken in the future should be considered.
In most workplaces, information and communication technology (ICT) systems are an integral part of all business operations. In practice, these are often the main drivers of work changes but are commonly overlooked as sources of workplace risks. Opportunities to improve health and safety should always be considered when new ICT systems are planned and introduced.
The HOW Principles
Principle 7: Engage decision-makers and leaders
- Work design or redesign is most effective when there is a high level of visible commitment, practical support, and engagement by decision-makers.
- Demonstrating the long-term benefits of investing in good work design helps engage decision-makers and leaders.
- Practical support for good work design includes the allocation of appropriate time and resources to undertake effective work design or redesign processes.
Information: Leaders are the key decision-makers or those who influence the key decision-makers. Leaders can be the owners of a business, directors of boards, and senior executives.
Leaders can support good work design by ensuring the principles are appropriately included or applied, for example in:
- key organizational policies and procedures
- proposals and contracts for workplace change or design
- managers’ responsibilities and as key performance indicators
- business management systems and audit reports
- organizational communications such as a standing item on leadership meeting agendas, and
- the provision of sufficient human and financial resources.
Good work design, especially for complex issues will require adequate time and resources to consider and appropriately manage organizational and/or technological change. Like all business changes, research shows that leader commitment to upfront planning helps ensure better outcomes.
Managers and work health and safety advisors can help this process by providing their leaders with appropriate and timely information. This could include for example:
- identifying design options that support both business outcomes and work health and safety objectives
- assessing the risks and providing short and long term cost-benefit analysis of the recommended controls to manage these risks, and
- identifying what decisions need to be taken, when and by whom to effectively design and implement the agreed changes.
Principle 8: Actively involve the people who do the work, including those in the supply chain and networks
- Persons conducting a business or undertaking (PCBUs) must consult with their workers and others likely to be affected by work in accordance with the work health and safety laws.
- Supply chain stakeholders should be consulted as they have local expertise about the work and can help improve work design for upstream and downstream participants.
- Consultation should promote the sharing of relevant information and provide opportunities for workers to express their views, raise issues, and contribute to decision-making where possible.
Effective consultation and cooperation of all involved with open lines of communication will ultimately give the best outcomes. Consulting with those who do the work not only makes good sense, it is required under the WHS laws.
Information: Under the model WHS laws (s47), a business owner must, so far as is reasonably practicable, consult with ‘workers who carry out work for the business or undertaking who are, or are likely to be, directly affected by a matter relating to work health or safety.’ This can include a work design issue.
If more than one person has a duty in relation to the same matter, ‘each person with the duty must, so far as is reasonably practicable, consult, co-operate and co-ordinate activities with all other persons who have a duty in relation to the same matter’ (model WHS laws s46).
Workers have knowledge about their own job and often have suggestions on how to solve a specific problem. Discussing design options with them will help promote their ownership of the changes. See Code of practice on consultation.
Businesses that operate as part of a supply chain should consider whether the work design and changes to the work design might negatively impact on upstream or downstream businesses. The supply chain partners will often have solutions to logistics problems that can benefit all parties.
Principle 9: Identify hazards, assess and control risks, and seek continuous improvement
- A systematic risk management approach should be applied in every workplace.
- Designing good work is part of the business process and not a one-off event.
- Sustainability in the long-term requires that designs or redesigns are continually monitored and adjusted to adapt to changes in the workplace so as to ensure feedback is provided and that new information is used to improve the design.
Good work design should systematically apply the risk management approach to workplace hazards and risks. See Principle 4 for more details.
Typically good work design will involve ongoing discussions with all stakeholders to keep refining the design options. Each stage in the good work design process should have decision points for review of options and to consult further if these are not acceptable. This allows for flexibility to quickly respond to unanticipated and adverse outcomes.
Figure 5 outlines how the risk management steps can be applied in the design process
Continuous improvements in work health and safety can in part be achieved if the good work design principles are applied at business start-ups and whenever major organizational changes are contemplated. To be most effective, consideration of health and safety issues should be integrated into normal business risk management.
Principle 10: Learn from experts, evidence, and experience
- Continuous improvement in work design and hence work health and safety requires ongoing collaboration between the various experts involved in the work design process.
- Various people with specific skills and expertise may need to be consulted in the design stage to fill any knowledge gaps. It is important to recognize the strengths and limitations of a single expert’s knowledge.
- Near misses, injuries and illnesses are important sources of information about poor design.
Most work design processes will require collaboration and cooperation between internal and sometimes external experts. Internal advice can be sought from workers, line managers, technical support and maintenance staff, engineers, ICT systems designers, work health and safety advisors, and human resource personnel.
Depending on the design issue, external experts may be required such as architects, engineers, ergonomists, occupational hygienists, and psychologists.
Information: If you provide advice on work design options it is important to know and work within the limitations of your discipline’s knowledge and expertise. Where required make sure you seek advice and collaborate with other appropriate design experts.
For complex and high-risk projects, ideally, a core group of the same people should remain involved during both the design and implementation phases with other experts brought in as necessary.
The type of expert will always depend on the circumstances. When assessing the suitability of an expert consider their qualifications, skills, relevant knowledge, technical expertise, industry experience, reputation, communication skills, and membership of professional associations.
Information: Is the consultant suitably qualified?
A suitably qualified person has the knowledge, skills, and experience to provide advice on a specific design issue. You can usually check with the professional association to see if the consultant is certified or otherwise recognized by them to provide work design advice.
The decision to design or redesign work should be based on sound evidence. Typically this evidence will come from many sources such as both proactive and reactive indicators, information about new technology, or the business decisions to downsize, expand or restructure or to meet the requirements of supply chain partners.
Proactive and reactive indicators can also be used to monitor the effectiveness and efficiency of the design solution.
Information: Proactive indicators provide early information about the work system that can be used to prevent accidents or harm. These might include for example: key process variables such as temperature or workplace systems indicators such as the number of safety audits and inspections undertaken.
Reactive indicators are usually based on incidents that have already occurred. Examples include the number and type of near misses and worker injury and illness rates.
Useful information about common work design problems and solutions can also often be obtained from:
- work health and safety regulators
- industry associations and unions
- trade magazines and suppliers, and
- specific research papers.
Good Work Design: Summary
The ten principles of good work design can be applied to help support better work health and safety outcomes and business productivity. They are deliberately high level and should be broadly applicable across the range of Australian businesses and workplaces. Just as every workplace is unique, so is the way each principle can be applied in practice.
When considering these principles in any work design also ensure you take into account your local jurisdictional work health and safety requirements.

with fields full of grain
I have to see you
again and again
Mediæval Andalusia, or al-Andalus, was the region of Iberia under Muslim rule, its constantly shifting boundaries comprising, at their greatest extent, the entire territory of modern Spain and Portugal (plus a bit more), and at their smallest extent, just the area around Granada. (So, not quite the same territory as “Andalusia” today.)
This period, known for its many scientific and cultural achievements, has long been hailed as one in which (for much of the period, anyway) Muslims, Christians, and Jews were able to coexist and cooperate on peaceful and productive terms – an island of interfaith toleration and convivencia compared to the Christian kingdoms to the north and the more conservative Berber Muslim kingdoms to the south (both of which made repeated incursions into the region, bringing less tolerant policies with them).
Libertarians in particular will be familiar with Rose Wilder Lane’s enthusiastic endorsement of this thesis; and the beautiful 2007 documentary Cities of Light: The Rise and Fall of Islamic Spain defends the same viewpoint:
There’ve always been dissenters from this interpretation, of course, and in recent years they’ve grown increasingly vocal. This historical dispute is also very much entangled with contemporary politics; even though nothing about the present-day prospects for peaceful coexistence follows with anything like apodictic necessity from what people a millennium or so ago did or did not manage to achieve (especially given how much all the relevant cultures have changed since then), there’s nevertheless a tendency for those who are optimistic about the prospects for interfaith toleration today to point to al-Andalus as a positive model, while those who adopt a more belligerent clash-of-civilisations view tend to view al-Andalus in a negative light as well.
For those interested in getting an accurate understanding of the period, I recommend the following three books:
- The Ornament of the World: How Muslims, Jews, and Christians Created a Culture of Tolerance in Medieval Spain by Maria Rosa Menocal
- The Myth of the Andalusian Paradise: Muslims, Christians, and Jews under Islamic Rule in Medieval Spain by Darío Fernández-Morera
- Under Crescent and Cross: The Jews in the Middle Ages by Mark R. Cohen
As you might guess from their titles, Menocal’s and Fernández-Morera’s books occupy opposing sides in this dispute; Menocal paints an especially rosy picture of the Andalusian convivencia, while Fernández-Morera takes the opposite line, arguing that al-Andalus was not only intolerant and oppressive, but much more intolerant and oppressive than Christian Europe. Cohen, for his part, takes a moderate view, opposing both the “myth of the interfaith utopia” and the “countermyth of Islamic persecution.” (Cohen’s book is both broader and narrower in focus than the other two – broader, in dealing with the Muslim world as a whole rather than just al-Andalus, and narrower, in dealing specifically with the treatment of Jews – but it nevertheless covers much of the same territory. And while the first edition of Cohen’s book came out before those of Menocal and Fernández-Morera, the most recent edition has an introduction specifically addressing their views. Oddly, Fernández-Morera cites Cohen’s work with high praise, as though they were in agreement, which they aren’t.)
I think one will get a juster picture from reading all three of these books than from reading just one. In my view, Menocal greatly exaggerates the virtues of the Andalusian regime, and Fernández-Morera greatly exaggerates its vices. But that makes them both useful if read with caution, because each makes points that serve as useful correctives to the other’s excesses. And then Cohen (whose interpretations seem to me to be generally the most reasonable) takes a more moderate position that serves as a check on both. (But Menocal and Fernández-Morera cover much material that Cohen doesn’t, so one can’t simply steer by Cohen alone.)
Interestingly, if read carefully the three authors turn out hardly ever to disagree about the historical facts (despite Fernández-Morera’s pose as heroic exposer of the lies of academic orthodoxy); it’s much more a matter of selection and emphasis. There was, in fact, quite a bit of peaceful economic and intellectual cooperation between Muslims and non-Muslims in al-Andalus; there was also, in fact, quite a bit of oppression and persecution. Which aspect was dominant varied by time and region, as one might expect from a nearly 800-year history comprising multiple changing regimes. I find both Menocal and Fernández-Morera to be a bit slippery in this regard.
As an example of where Menocal is misleading: she downplays some of the worst cases of persecution, such as one series of executions in Córdoba in the 850s, concerning which she suggests that the victims – Christians who had denounced Muhammad as a false prophet – were essentially asking for it; Menocal chillingly dismisses them as “wild-eyed, out-of-control radicals” and “would-be martyrs” who “knew for a certainty that they were forcing the hands of the authorities of the city by expressly choosing to vilify Muhammad.” Here Fernández-Morera includes some details that Menocal conveniently omits:
The first one to die as a martyr was a well-educated monk named Perfectus. In 850 [he] encountered some Muslims he knew, who asked him to explain what Christians thought of Christ and the Prophet Muhammad. He told them that they might not like the answer. When they insisted, Perfectus made them promise not to tell his answer to anyone. He proceeded to cite a passage from the gospel in which Christ declares that “many false prophets will come in my name,” and Perfectus added that Christians believed Muhammad to be one of these false prophets. … Some days later, the same Muslims saw him in the city, pointed him out to the crowds, and accused him of having insulted the Prophet. The monk was arrested and locked in prison [and eventually] was publicly beheaded.
This does not sound like the story of someone seeking martyrdom.
Again, when Menocal speaks blithely of the role of “women who sang for a living, young and attractive entertainers much prized in the Andalusian courts,” Fernández-Morera reminds us that most of these women were in fact slaves, and indeed essentially sex-slaves.
On the other hand, Fernández-Morera (who is incidentally a classical liberal of Austrian bent – gooble gobble, one of us!) for his part downplays the fact that these slave women of the Andalusian courts often fell, whether by sale or by conquest, into Christian hands, in the courts of the Andalusians’ northern neighbours – and their new Christian owners did not choose to free them. So as a special indictment of Muslim as opposed to Christian rule, the example falls short. (And certainly not all the women artists of Islamic courts were slaves.)
There is a still greater obstacle to Fernández-Morera’s suggestion that the Muslims were worse than the Christians in the area of religious oppression. He spends a lot of time talking about the burdensome restrictions placed on Christians by Muslim regimes, and fair enough; but he offers no comparable discussion of restrictions placed on Muslims by Christian regimes. That’s because there’s nothing to tell; in Christian regimes (with the exception of the Crusader kingdoms, whose rulers had to a great extent “gone native”), being a Muslim was illegal. By contrast, in most Muslim regimes, most of the time, being a Christian was not illegal. So if one wants to compare Muslim treatment of Christians with Christian treatment of Muslims, no number of examples of anti-Christian oppression is going to make the Muslims come out looking worse than the Christians’ complete ban on Islam.
Any comparative thesis with regard to religious oppression is thus going to have to turn instead on the treatment of Jews, a group relegated to second-class status by both Muslims and Christians – and here Cohen shows pretty convincingly that, in general, mediæval Islam was “more tolerant toward nonconforming minorities than Christianity” and that the contrary suggestion “ignores, one might say suppresses, the substantial security – at times verging on social (though not legal) parity – that Jews enjoyed through centuries of existence under Muslim rule.” (And of course when the Christians finally succeeded in driving all the Muslims out of Iberia, they drove all the Jews out along with them; many found refuge in the more tolerant Ottoman Empire.) Cohen’s explanation for Islam’s being more tolerant toward Jews than Christians were is that a religion founded by a merchant is naturally less prone to a certain traditional antisemitic prejudices. Another possibility I would point to is that mainstream Christianity’s distinctive theological doctrines (e.g., trinity and incarnation) render it more different from Islam and Judaism than the latter are from one another. (As for why Muslims tolerated Christians more than Christians tolerated Muslims, I’d assume this is related to the reason that Christians tolerated Jews at all, despite not tolerating Muslims: Christianity and Islam each tolerated the doctrines they regarded as forerunners of their own, but not doctrines that proposed to be their successors. Christianity and Islam each wanted to be the final revelation.)
There’s also a certain terminological slipperiness that both Menocal and Fernández-Morera seem to me to be guilty of. Words like “tolerance” and “toleration,” for example, carry a range of meanings, from grudging sufferance at one extreme (“I don’t like my cousin, but I tolerate him”) to the whole-hearted embrace of diversity and equal rights at the other extreme. Menocal will offer persuasive evidence for the existence of toleration in a weaker sense, and then follow it up with rhetoric appropriate to having shown the existence of toleration in a strong sense. Fernández-Morera, for his part, will offer persuasive evidence for the non-existence of toleration in a strong sense, and then follow it up with rhetoric appropriate to having shown the non-existence of toleration in a weaker sense. Thus the two authors manage to give completely opposite impressions, despite for the most part never literally contradicting each other. (Similar remarks apply to the term convivencia.)
The usually more sober Cohen manages to trip himself up over terminology too. He tells us early on that his book is “not a comparative study of tolerance,” since “[n]either for Islam, nor for Christianity prior to modern times, did tolerance, at least as we in the West have understood it since John Locke, constitute a virtue.” In other words, it makes no sense to ask whether X is more or less tolerant than Y unless we are prepared to say that X and Y both meet some minimum liberal standard for tolerance. But is that really how these words work? Admittedly some terms do work that way; while I think Prague is more beautiful than Kraków, I would not express that by saying that Kraków is uglier than Prague, because that does ordinarily seem to imply that Kraków is ugly, full stop, which it certainly is not. On the other hand, if I say that a mouse is larger than a mosquito, that does not seem to imply that the mouse is large, full stop. It’s not obvious to me that “tolerant” works more like “ugly” than like “large.” In any case, in the rest of his book Cohen cheerfully forgets this opening stricture and speaks regularly of mediæval Muslim societies being more tolerant than their Christian counterparts.
Continuing the terminological theme: Fernández-Morera also seems to think that the common use of the term “Iberia,” rather than “Spain,” to refer to the Iberian peninsula during the Middle Ages, is a “politically correct” subterfuge to avoid offending Muslims (despite the fact that both the subtitle of Menocal’s book and the subtitle of the Cities of Light documentary unembarrassedly say “Spain”). I should have thought the more obvious motivation would be to avoid any confusion that might arise from the fact that “Spain,” today, is the name of a distinct nation-state that shares the Iberian peninsula with another nation-state, Portugal. (I’m leaving aside Andorra and Gibraltar as small enough to be ignored, as San Marino and Vatican City are in speaking of “Italy”; but Portugal is larger and more populous than, say, Austria.)
Another slipperiness I find in Fernández-Morera is this: As he notes, when Muslim regimes in al-Andalus pursued policies of (relative) tolerance, this was typically a decision of kings and princes, often opposed by clerics. But clerics, not kings and princes, Fernández-Morera says, are the true authorised spokesmen for Islam. Hence tolerant policies by Muslim princes do not count as establishing the tolerant character of the regime, because the real policies of any Islamic regime are those favoured by its clerics, not those favoured by its king – even in those cases where the clerics have no power to enforce their preferences, and the king is in a position to simply ignore the clerics. This seems a bit of a stretch – especially considering that in Islam there was no one institution with the authority to declare what was or was not Islamic, comparable to the power claimed (though not unchallenged either, FWIW) by the Catholic church. So it’s unclear why we should regard the clerics’ determinations as more “Islamic” than those of the kings. (Relatedly, Fernández-Morera tells us that “Muslims in al-Andalus lived under a …. hierocracy – a government of clerics”; but for Fernández-Morera this “government of clerics” remains in force even when the king’s decisions, in defiance of the clerics, are the ones that actually carry the day. Fernández-Morera’s clerics sometimes seem to savour a bit of Emperor Norton.)
All this doesn’t mean that Muslim rulers had enlightened and liberal motives for their more-tolerant policies. After all, under Islamic law Jews and Christians paid a tax from which Muslims were exempt, which could plausibly have had the economic effect of weakening any incentive, on the part of those collecting the tax, either to pressure Jews and Christians into conversion or to drive them out. Then again, on the other hand, those raised in a cosmopolitan court atmosphere might well have developed a genuine affinity, even if perhaps more an æsthetic than a moral one, for an atmosphere of diversity and intercultural exchange. In any case, whatever the reasons, Muslim regimes in al-Andalus did foster conditions for such exchange, even if not as thoroughly and consistently as in justice they should have, that their counterparts in Christian Europe did not.
So my final verdict is, broadly, one cheer for Fernández-Morera, two cheers for Menocal, and three cheers for Cohen. | <urn:uuid:707ba255-0d85-4d36-8cf5-1755fac4f262> | CC-MAIN-2024-51 | https://aaeblog.com/2019/09/convivencia-in-my-dreams-it-always-seems/ | 2024-12-10T14:33:13Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066061339.24/warc/CC-MAIN-20241210132922-20241210162922-00000.warc.gz | en | 0.963359 | 3,303 | 2.828125 | 3 |
At night the river looked deeper than ever as the woman rowed across it with her three small children. That was dangerous enough but they were being pursued. They were being shot at. They were fleeing for their lives.
The Civil War had just begun. The woman and her children were slaves. They had fled Missouri and were crossing over into the Northern state of Illinois, and to freedom. That night, the woman evaded her pursuers. When she landed on the northern bank of the river she pulled her children to their knees and prayed: ‘Now, you are free; never forget the goodness of the Lord‘. And, with that, one of her children, Augustine Tolton, later to become the first African-American to be ordained priest, was ‘freed’.
Augustine Tolton was born 1 April, 1854. His parents were slaves, so he too became one. His parents were Catholics, so he too was baptised into his parents’ Holy Faith. His father, Peter, was an honest and good man well liked by his slave owner for whom he worked hard. Seven years after Augustine, or Gus as he was known, was born, war broke out between the States. Peter talked to his wife, Martha, of his desire to escape and enlist in the Union army. As he did so he gazed at the three children sleeping and began to talk of his hopes for their future, one in which they would be free. The Toltons’ Catholic faith was deeply held and urged them on to action. Martha readily agreed that her husband must go – and that some day they would all be together again, and free. They embraced. With one last look at his children, Peter headed out into the night, to the North, and to war. The couple were never to see each other again; the children were never again to play with their father. He lies in an unmarked grave near the scene of a battle, having fought and died that his children would one day be free.
Racial prejudice was not confined to the South. When, finally, the Tolton family arrived in the Illinois town of Quincy, they were to live in a segregated neighbourhood. Nevertheless, Mrs Tolton soon found work and, thereafter, supported her children as best she could. Before anything else, however, the nearest Catholic Church, St. Peter’s, was identified and the family started to worship there. But, racial prejudice was also found there. Northern congregations resented the recent influx of blacks from the South. The Parish Priest was an Irishman, Brian McGirr, and he was having none of it. He knew that there was a simmering resentment in his congregation. He tackled it head on with sermons reminding all listening that as children of God there was but one Father and whatever you do to the least you do to Him.
Gus grew up quickly. A bright and intelligent boy, with a good heart, aged nine, he was helping support his family by working at a local tobacco factory. His employers liked him; he worked hard and was reliable. The future for the Tolton family began to become clearer when the Civil War finally ended with victory for the North and an end to slavery throughout the United States. Gus was not insensitive to what that ‘victory’ actually meant to many of the freed slaves whom he lived alongside, including his own family: servile work for some, lives of poverty for most.
Just as with his father before him, Gus was an idealist. His idealism was not political though; it was religious. He loved his Catholic faith. The Tolton family had remained regular worshippers at St. Peter’s. Gus participated as much as he could in parish activities: learning to serve Holy Mass, and then going on to be a lay catechist. His human virtues and obvious piety did not go unremarked by the redoubtable Fr. McGirr. One day the Parish Priest saw Gus praying alone in church. That was not an unusual sight; however, that day there was a change. As he looked at the face of the young man he noticed something…Later he asked Gus what he had been praying about. The young man looked embarrassed. For some time previously Fr. McGirr had wanted to ask him a question. That day he did. It shocked Gus because it was on that very subject he had been praying namely, a possible vocation to the priesthood.
Fr. McGirr was keen to progress this proposition. Gus was delighted; for, with all his heart, he wanted to be a priest; it was a sense that had been growing for some years. The formality of applying to a seminary proved, however, more complicated for the young recently freed slave, especially as there had never been a man of his race at any seminary in America. In reply to his letters, excuses were made as to why he could not be accommodated. Religious orders were also tried, but to no avail.
So Gus was left to continue working at the cigar factory. For years he persevered; eventually promoted by his employers, it proved a small consolation. Still, he went to Holy Mass as often as he could; he prayed daily. He waited. During this period, only his mother and Fr. McGirr knew the frustration and sadness that clung to the outwardly smiling Gus Tolton. He refused to be discouraged or to blame anyone. He knew the human heart was weak; he knew too that the Church was unimpeachable in its treatment of all as brothers and sisters in Christ but that she was made up of sinners, and so human frailty was never far away. He continued to pray, to give classes to his fellow parishioners, to wait, and to hope.
He never was to study at a seminary in the United States. After many years he was eventually accepted at a Pontifical university in Rome. On 21 February 1880, Gus left America bound for Europe, destined to be a missionary in Africa. He loved his time in the Eternal City. His fellow students loved him too, and his professors held him in high regard. For the first time in his life he lived in an environment free from racial discrimination. He thrived. He was an apt scholar. Having picked up German in Quincy, he was to leave Europe with French and Italian mastered, to say nothing of Latin. During these relatively carefree years, the only question was where he would be posted. In the end, to his surprise, he was sent back to where he had come from. The authorities in Rome could see no reason why he could not minister to his co-religionists there, not least those of his own race.
In July 1886, Fr. Tolton’s homecoming caused a stir. At Quincy station there was a large and noisy crowd to welcome him. Both black and white, Catholic and non-Catholic came to see the young man who had left a much-loved friend and fellow worker and who now returned in a black soutane with a red sash. That day, however, there was one who stood apart from the crowd and quietly watched with tears in her eyes as her son returned to her a priest. He was always conscious that his vocation was as a result of his mother’s example and the Christian home she had provided for him, in spite of everything. In hindsight, however, looking at that day’s generous welcome from all quarters, it was bitter sweet. One could even say it was Fr. Tolton’s Palm Sunday. Despite his open and generous manner, his learning and piety, his hard work and dedication, and above all his priestly heart and its desire for souls, he was to be defamed, insulted and ultimately rejected. Not least by a fellow priest, part inspired by jealousy and part by racial prejudice, that, in the end, caused the young priest’s removal.
Just over three years after his triumphal return, Fr. Augustine Tolton was alone on a night train in a segregated carriage heading to Chicago where he had been assigned to care for that city’s growing black population.
Trusting all to Providence, the same fervour and energy that Fr. Tolton had brought to Quincy was now loosed upon a poor district of Chicago’s south side. With his bishop’s approval, the young priest set about raising funds for a church. Funds were raised and the basis of a great and beautiful church, St. Monica’s, dedicated to the service of the city’s black population was started. He was more than a fundraiser though. He was first and foremost a priest. His congregation was largely poor, ill-educated ex-slaves, with all the resultant ills of depression and violence attending those who, for varying reasons, had given up on life. The young priest worked tirelessly to minister to them, reminding them of the one thing no human power could remove or tarnish: their Catholic Faith.
A visiting priest met Fr. Tolton at this time and stayed with him and his mother – who by then also had come to be live in Chicago as her son’s housekeeper. Unlike the city’s richer parishes, Fr. Tolton lived in reduced circumstances. Nevertheless, the visiting priest found a hearty welcome. He also found a cultured and holy priest, one who complained of nothing and prayed for everything. At the end of the evening, when dinner had finished, the visitor observed how the younger priest took a set of Rosary beads hanging from a nail on a wall nearby and, with his mother beside him, knelt on the stone floor to recite that ancient prayer – just as they always had done, not least when they had arrived frightened and anxious having fled slavery those years previously.
Unexpectedly, when aged only 43, having at last been able to attend a retreat for priests, on returning by train, Fr. Tolton felt unwell. Just outside the train station he had been seen to stumble and then collapse on the city street. As an ambulance was called, a crowd gathered around the unusual sight of a black man dressed in a faded cassock. He was taken to a nearby hospital. Around his bedside were the hospital chaplain who had administered the Last Rites, some nuns praying, and his mother. On 9 July 1897, he died as a priest should – worn out in the care of his flock.
Fr. Tolton had asked to be buried in Quincy. His body was returned there and interred in a simple grave by St. Peter’s Church. It was the same church where he had served Mass and given catechism classes after he had finished his work at the local factory. Some were surprised that he had chosen to be buried in the town that had shunned him. Perhaps they had forgotten that it was there, decades earlier, that a frightened black woman had come with her three small children having fled slavery to find freedom, and where a hope for a better future was born for her and her children.
Laid to rest on that July day in 1897, and having entered into the mysterious freedom of the Children of God where there is neither Greek nor Jew, neither freed nor slave … Fr. Augustine Tolton was now, at last, truly free.
By all accounts, his mother, having continued to work as a priest’s housekeeper died an equally holy death in 1911. St. Monica’s, the church for which her son had expended so much energy and time, was abandoned in 1924 and later raised to the ground.
The Faith is more than bricks and mortar, however, and, in 2011, after an initial investigation at the behest of the Archdiocese of Chicago, Fr. Augustine Tolton was declared: Servant of God. The ‘stone’ rejected had become a ‘living stone’, one upon which now future generations would build.

Hyperactivity and Attention: Understanding the Connection
Define hyperactivity and attention-related disorders
Hyperactivity and attention-related disorders, such as Attention Deficit Hyperactivity Disorder (ADHD), are neurodevelopmental conditions that affect an individual’s ability to pay attention, control impulsive behaviors, and manage hyperactivity.
ADHD is characterized by a persistent pattern of inattention and/or hyperactivity-impulsivity that interferes with daily functioning and development. Symptoms of ADHD may include difficulty sustaining attention, forgetfulness, disorganization, impulsivity, excessive talking, fidgeting, and restlessness.
Prevalence rates of ADHD vary, but it is estimated that approximately 5-10% of children and 2-5% of adults worldwide are affected by this disorder. Boys are diagnosed with ADHD more often than girls, and it typically persists into adolescence and adulthood, although symptoms may change over time.
Diagnosing hyperactivity and attention-related disorders involves a comprehensive evaluation that considers the individual’s history, symptoms, and functional impairment. A diagnosis of ADHD is made based on specific criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).
It is important to note that hyperactivity and attention-related disorders are considered neurodevelopmental conditions, meaning they are believed to arise from underlying brain development issues. These conditions are not caused by laziness, lack of intelligence, or poor parenting, but rather result from complex interactions between genetic, biological, environmental, and social factors.
By understanding the symptoms and prevalence rates of hyperactivity and attention-related disorders, individuals can better recognize the challenges faced by those with ADHD and work towards creating a supportive and understanding environment for individuals with these conditions.
Explore the underlying causes and risk factors
One of the factors that can contribute to the development of hyperactivity and attention-related disorders is genetic predisposition. Research has shown that there is a hereditary component to these disorders, with a higher likelihood of occurrence among individuals who have a family history of ADHD or similar conditions. Certain genes have been identified as potential contributors to the development of these disorders, although the specific mechanisms are still being studied.
Brain Structure Abnormalities
Another factor that may play a role in the development of hyperactivity and attention-related disorders is abnormalities in brain structure. Studies have found differences in the size and activity of certain brain regions, such as the prefrontal cortex, which is responsible for executive functions. These structural abnormalities can impact an individual’s ability to regulate attention and control impulsive behaviors, leading to the symptoms observed in ADHD.
Prenatal Exposure to Toxins
Exposure to certain toxins during pregnancy has also been investigated as a potential risk factor for hyperactivity and attention-related disorders. Substances like lead, tobacco smoke, alcohol, and certain chemicals found in the environment have been linked to an increased risk of these conditions. Prenatal exposure to these toxins can negatively impact the developing brain and contribute to the manifestation of hyperactive and inattentive behaviors later in life.
Environmental factors, such as parenting styles and academic stress, can also influence the development of hyperactivity and attention-related disorders. Inconsistent or overly strict parenting, as well as high levels of stress within the family, may contribute to the manifestation of these conditions. Additionally, academic stress and high demands in educational settings can exacerbate symptoms and make it more challenging for individuals with hyperactivity and attention difficulties to cope effectively.
In conclusion, hyperactivity and attention-related disorders have a complex etiology that involves various factors. Genetic predisposition, brain structure abnormalities, prenatal exposure to toxins, and environmental factors like parenting styles and academic stress all play a role in the development of these conditions. Understanding these underlying causes and risk factors is crucial for developing effective interventions and strategies to support individuals with hyperactivity and attention-related disorders.
Understanding the Link between Hyperactivity and Attention
Hyperactivity and attention difficulties are closely interconnected and often coexist, particularly in individuals with attention deficit hyperactivity disorder (ADHD). This link between hyperactivity and attention has profound implications for individuals’ functioning and daily lives.
1. Coexistence of Hyperactivity and Inattentiveness:
- Hyperactivity and inattention are considered core features of ADHD.
- While hyperactivity refers to excessive physical movements like fidgeting and restlessness, inattentiveness involves difficulties in sustaining focus and maintaining attention.
- These two symptoms often occur together, and their presence is essential for diagnosing ADHD.
2. Effects on Academic Performance:
- Hyperactive behaviors can significantly impede an individual’s ability to concentrate in a classroom setting, leading to poor academic performance.
- Inattentiveness may cause difficulties in following instructions and completing assignments, further impacting learning outcomes.
- Both hyperactivity and attention difficulties can disrupt students’ engagement and participation in educational activities.
3. Challenges in Social Relationships:
- The combination of hyperactivity and attention difficulties can affect an individual’s ability to maintain positive social relationships.
- Hyperactive behaviors, such as impulsivity and difficulty waiting for turns, may lead to social conflicts or problems with peer interactions.
- Poor attention control can also result in difficulties listening to others, effectively communicating, and engaging in reciprocal conversations.
4. Occupational Implications:
- For individuals with hyperactivity and attention-related disorders, the challenges they face extend beyond academic settings into the workplace.
- Hyperactive behaviors, like restlessness and fidgeting, can negatively impact productivity and work performance.
- Inattentiveness may lead to difficulties in focusing on tasks, sustaining attention, and maintaining organization and time management skills.
Understanding the profound impact of hyperactivity on attention and vice versa helps individuals, their families, and educators recognize the need for appropriate support and interventions to address these challenges effectively.
Analyzing the Impact of Hyperactivity on Attention and Vice Versa
Hyperactivity and attention-related disorders, such as attention deficit hyperactivity disorder (ADHD), often coexist and can have a significant impact on an individual’s ability to sustain attention and engage in tasks that require focused effort. In this section, we will delve deeper into how hyperactivity affects attention and vice versa, highlighting the challenges faced by individuals with these disorders.
Impact of Hyperactivity on Attention
- Fidgeting: Hyperactive behaviors, such as constant fidgeting or squirming, can make it difficult for individuals to maintain their attention on a specific task. This restlessness can be distracting and inhibit their ability to concentrate.
- Restlessness: Individuals with hyperactivity may have a constant need for movement and struggle to sit still. This restlessness can make it challenging for them to remain engaged in tasks that require sustained attention.
- Impulsivity: Impulsive behaviors, common in individuals with ADHD, can disrupt attention by interrupting ongoing activities abruptly. These impulsive actions may distract the individual and divert their focus from the task at hand.
- Inability to sustain focus: Hyperactivity can make it challenging for individuals to sustain their attention over an extended period. This difficulty in maintaining focus can lead to decreased productivity and hinder their performance in various domains, such as academics or work.
Impact of Attention Difficulties on Hyperactivity
- Distractibility: Attention difficulties in individuals with ADHD often manifest as being easily distracted or having difficulty filtering out irrelevant stimuli. This distractibility can contribute to restlessness and impulsive actions, creating a cycle that exacerbates hyperactive behaviors.
- Inability to engage in tasks: Attention deficits can make it difficult for individuals to engage in activities that require sustained effort and attention. This inability to fully participate in tasks may lead to restlessness or impulsive behaviors as individuals struggle to maintain interest or focus.
- Difficulties with organization and planning: Attention difficulties can impair an individual’s ability to organize their thoughts and plan their actions effectively. This can contribute to hyperactivity, as individuals may become overwhelmed by the demands of a task and resort to impulsive or restless behaviors.
- Reduced inhibitory control: Inhibition, a key executive function, is often compromised in individuals with attention difficulties. This lack of inhibitory control can contribute to impulsivity and hyperactivity, as individuals may struggle to regulate their impulses and resist the urge to engage in restless behaviors.
Understanding the impact of hyperactivity on attention and vice versa is essential for developing effective interventions and strategies for individuals with hyperactivity and attention-related disorders. By addressing both components of these disorders, individuals can receive comprehensive support and guidance to manage their symptoms and improve their overall quality of life. In the next section, we will explore the role of executive functions in hyperactivity and attention, further highlighting the cognitive processes that contribute to these disorders.
Understanding the Role of Executive Functions in Hyperactivity and Attention
Executive functions, a set of cognitive processes responsible for self-regulation, planning, and goal-directed behavior, play a significant role in hyperactivity and attention-related disorders. These cognitive processes are essential for individuals to effectively manage their thoughts, emotions, and actions.
Deficits in Inhibitory Control
One key aspect of executive functions is inhibitory control, which is the ability to inhibit or control impulsive behaviors. Individuals with hyperactivity and attention-related disorders often struggle with inhibitory control, leading to difficulties in resisting immediate temptations or impulses. This lack of control can manifest in behaviors such as blurting out answers, interrupting others, or acting impulsively without considering the consequences.
Challenges with Working Memory
Working memory, another component of executive functions, refers to the ability to hold and manipulate information in our minds while performing tasks. Individuals with hyperactivity and attention-related disorders often have challenges with working memory, leading to difficulties in organizing thoughts, following instructions, or remembering information. This can impact their ability to complete tasks that require multi-step processes or sustained mental effort.
Planning and Goal-Directed Behavior
Executive functions also involve planning and goal-directed behavior, which are essential for setting goals, creating strategies, and carrying out tasks in a structured manner. Individuals with hyperactivity and attention-related disorders may struggle with initiating and maintaining focused attention on tasks, making it difficult for them to plan and achieve specific goals. This can lead to inefficiency, disorganization, and difficulties in meeting deadlines or completing tasks within a given timeframe.
Implications for Intervention and Strategies
Understanding the connection between executive functions and hyperactivity and attention-related disorders is crucial for developing effective interventions and strategies. By focusing on improving inhibitory control, working memory, and planning skills, individuals with these disorders can enhance their ability to self-regulate, sustain attention, and achieve desired outcomes.
Intervention Approaches for Executive Function Deficits
- Behavioral interventions: Implementing structured routines, task lists, and behavior contracts can help individuals establish order and reduce impulsivity.
- Psychoeducation: Providing individuals and their families with information about executive functions and how to develop strategies for managing them can empower them to take control of their behaviors and attention.
- Medication: In some cases, medication prescribed by healthcare professionals may be recommended to help regulate impulsivity and improve attention.
- Cognitive-behavioral therapy: This type of therapy focuses on helping individuals identify and challenge negative or impulsive thoughts and behaviors, promoting self-control and better attention management.
- Lifestyle modifications: Incorporating healthy lifestyle habits such as regular exercise, sufficient sleep, and a balanced diet can positively impact executive functions and overall well-being.
By addressing executive function deficits, individuals with hyperactivity and attention-related disorders can improve their ability to focus, regulate their impulses, and achieve their goals. It is important to tailor interventions and strategies to each individual’s specific needs to ensure the most effective outcomes.
Impact of Hyperactivity and Attention Difficulties on Daily Life
Hyperactivity and attention-related disorders, such as attention deficit hyperactivity disorder (ADHD), can have significant impacts on various aspects of individuals’ daily lives. These disorders affect functioning, relationships, education, and career prospects. Understanding these impacts is crucial in developing empathy and providing support to individuals affected by hyperactivity and attention difficulties.
One area greatly affected by hyperactivity and attention difficulties is education. The symptoms of ADHD, such as inattention and impulsivity, can make it challenging for individuals to concentrate in classroom settings, follow instructions, complete assignments, and stay organized. As a result, academic performance may suffer, leading to lower grades, difficulty in understanding complex concepts, and increased frustration both for the individual and their teachers.
According to the American Psychiatric Association, around 25% to 40% of individuals with ADHD experience learning disabilities. These difficulties may be related to poor organizational skills, problems with sustained attention, and limitations in working memory. Individuals may require additional support, such as individualized education plans (IEPs), accommodations, and classroom interventions to help them succeed academically.
The symptoms of hyperactivity and attention difficulties can also impact an individual’s relationships. Impulsivity, restlessness, and difficulty sustaining attention may make it challenging for individuals to engage in social interactions effectively. They may struggle with taking turns during conversations, interrupting others, and maintaining eye contact, which can lead to strained relationships with peers, friends, and family members.
Furthermore, individuals with hyperactivity and attention-related disorders may face social rejection, bullying, and feelings of isolation. These challenges can negatively impact their self-esteem and overall well-being. It is crucial to provide social skills training, support groups, and counseling services to help individuals develop strategies for improving their interpersonal relationships and building social connections.
The challenges associated with hyperactivity and attention difficulties can extend into the professional realm. Individuals may find it difficult to maintain focus, meet deadlines, stay organized, and manage time effectively. This can result in underperformance, problems with meeting workplace expectations, and potential career setbacks.
The National Resource Center on ADHD suggests that individuals with ADHD may benefit from strategies such as creating structured routines, breaking down tasks into smaller, manageable parts, and utilizing visual aids to enhance productivity. Additionally, providing accommodations and workplace support, such as flexible work hours or job coaching, can greatly assist individuals in managing their symptoms and optimizing their potential in the workplace.
Effects on Quality of Life
The impact of hyperactivity and attention difficulties goes beyond academic and occupational challenges. These disorders can significantly affect an individual’s overall quality of life. The constant struggle to stay focused, manage impulsivity, and cope with restlessness can lead to feelings of frustration, stress, and low self-esteem.
The Centers for Disease Control and Prevention highlight that individuals with ADHD may be at higher risk for developing co-existing mental health conditions, such as anxiety and depression. These conditions can further exacerbate the challenges associated with hyperactivity and attention difficulties, leading to a decreased sense of well-being and overall life satisfaction.
It is crucial to provide comprehensive support that addresses the emotional and psychological well-being of individuals with hyperactivity and attention-related disorders. This may involve therapy, counseling, and the development of coping mechanisms to manage stress and enhance self-esteem.
In conclusion, hyperactivity and attention difficulties have wide-ranging impacts on individuals’ daily lives, including challenges in education, relationships, and career prospects. By recognizing and addressing these effects, individuals with these disorders can receive the necessary support to enhance their functioning and overall quality of life.

Strategies for Managing Hyperactivity and Improving Attention
Individuals with hyperactivity and attention-related disorders, along with their families and caregivers, can benefit from various evidence-based strategies and interventions. These approaches, when implemented consistently and with professional guidance, can help manage hyperactivity symptoms and improve attention. Here are several strategies that have been effective in addressing these conditions:
Behavioral interventions aim to modify and shape behaviors associated with hyperactivity and attention difficulties. Techniques such as positive reinforcement, reward systems, and token economies can be used to encourage desired behaviors and discourage impulsive or disruptive actions.
One effective approach is the use of a structured routine. Establishing consistent schedules and expectations can help individuals with hyperactivity stay organized and focused. Breaking larger tasks into smaller, manageable steps can also enhance attention and task completion.
Another helpful behavioral intervention is the implementation of a calm-down strategy. Teaching individuals techniques for self-regulation, such as deep breathing exercises or mindfulness practices, can assist in managing hyperactivity and improving attention.
Educating individuals with hyperactivity and attention-related disorders, as well as their families and caregivers, about the nature of these conditions is essential. Understanding the symptoms, triggers, and challenges associated with hyperactivity and attention difficulties can help individuals develop coping strategies and foster empathy in their support system.
Psychiatrists, psychologists, and other mental health professionals can provide psychoeducation through individual or group therapy sessions. They can also recommend resources, such as books, articles, or online materials, that offer further information and guidance.
In some cases, medication may be prescribed to manage hyperactivity and improve attention. Stimulant medications, such as methylphenidate (Ritalin) or amphetamines (Adderall), are commonly used to reduce hyperactivity and impulsivity while enhancing focus.
It is important to note that medication should be prescribed and monitored by a qualified healthcare professional. Regular follow-up appointments are necessary to assess the effectiveness of the medication and make any necessary adjustments.
Cognitive-behavioral therapy (CBT) can help individuals with hyperactivity and attention-related disorders identify and change negative thought patterns and behaviors. Through CBT, individuals can develop coping mechanisms, problem-solving skills, and strategies for self-monitoring and self-regulation.
A CBT therapist can work one-on-one with individuals to address specific challenges related to hyperactivity and attention. They may also provide guidance on managing anxiety, improving self-esteem, and cultivating social skills.
Adopting certain lifestyle modifications can support individuals with hyperactivity and attention difficulties. Here are a few examples:
- Healthy diet: Consuming a balanced diet rich in vitamins, minerals, and omega-3 fatty acids can contribute to overall brain health and function.
- Regular exercise: Engaging in physical activities can help release excess energy and improve focus and attention.
- Adequate sleep: Establishing a consistent sleep routine and ensuring sufficient rest can enhance attention and reduce hyperactivity.
It is crucial to consult with healthcare professionals or specialists to determine which interventions and modifications are most appropriate for each individual. What works for one person may not be effective for another, as every case is unique.
By implementing these strategies and interventions, individuals with hyperactivity and attention-related disorders can better navigate their daily challenges and improve their overall quality of life.

BECAUSE YOU CARE ABOUT MEXICO
The rapidly disappearing Water Forest is the largest benefactor of Mexico’s most densely populated region, providing water and vital ecological services to over 23 million people. Its future is in jeopardy, but YOU can be part of the epic story to achieve its conservation!
The social, economic and political stability of Mexico, current and future, depend on the Water Forest’s ecological integrity. 30% of the national GDP is generated in the surrounding valleys. This is why the Water Forest is considered an issue of National Security. The Fundación Biosfera del Anáhuac (FUNBA) coordinates the in-depth project, collectively developed, for the sustainable future of this vitally important natural area.
The Water Forest is also home to the biodiversity that keeps the ecosystems and their ecological services properly functioning. 10% of its species are endemic, a total of 325 species of plants and animals found nowhere else on Earth.
Despite being surrounded by Central Mexico’s Megalopolis, the Water Forest is a rich and functional biological corridor, seriously menaced by multiple threats, including urban sprawl on all fronts and from within.
HOW YOU CAN HELP SAVE THE WATER FOREST
The Fundación Biosfera del Anáhuac, A.C. (FUNBA) was created in 2011 to address the alarming Water Forest conservation challenge.
FUNBA promotes cross-sector participation in the planning and comprehensive management of hydrological basins and micro-basins, achieving ambitious goals through alliances with key players of all sectors, with special emphasis on community and academic involvement.
And we need your help to sustain this important work. When you give to FUNBA you contribute to saving nature and civilization at a large-scale: the Water Forest’s 255,000 hectares, the surrounding Megalopolis, and the native communities that own the Water Forest lands.
You also enable the smaller-scale projects that build-up to making the big change happen, such as community participatory diagnosis and land-use planning, capacity building, and the design and lobbying for environmental public policies and law reforms

HEAR FROM THE FUNBA TEAM
In 2019, the Water Forest Initiative adopted the Collective Impact model to generate cross-sector collaboration towards sustainability of the Water Forest.
Led by FUNBA, five research institutions, ten community-based organizations, twelve representatives of other Water Forest communities, several federal and state government agencies, three private sector parties, and ten NGOs, co-created a five-year project.
This overall project is comprised of sixteen research for incidence subprojects, ranging from revisiting the legal framework to community-based land-use planning.
The overall project is conceived as a thorough trasdisciplinary, intercultural solution. Its innovative conceptual framework is the co-construction of knowledge for the co-production of ecosystem services.
Core to the project’s General Incidence Goal is optimizing the Water Forest’s capacity to provide water to local and surrounding communities as well as to ecosystems.
The overall project’s yearly budget is in the order of US$3.3 million.
We need your help to sustain this important work.

WATER FOREST FAQs
What is the Water Forest?
Despite being surrounded by Central Mexico’s Megalopolis, the Water Forest is a rich and functional biological corridor, seriously threatened by urban sprawl on all fronts and from within.
Why is the water forest area so crucial?
The main environmental services provided by the Water Forest, all of them irreplaceable, free, interdependent and threatened, are the following:
- Climate regulation against the urban thermal footprint in a region that becomes increasingly covered by cement: without the forest, in ten years regional temperatures would increase above the yearly estimated median.
- Oxygen exchange through carbon capture: without the Water Forest, air quality would be unsustainable for living conditions to at least a third of the population during the dry season.
- Water supply to at least 23 million people.
- Mexico’s most biodiverse ecosystem in the smallest area in Mexico: a super diverse area in species and ecosystem processes, biological sustenance for the Water Forest’s very existence. Home to the biodiversity that keeps the ecosystem and their ecological services functioning properly.
- The natural areas adjacent to the cities are their only buffer against environmental contingencies.
- Depending on what researchers inform you, the Water Forest benefits 23 to 32 million people.
- The Water Forest mitigates the effects of climate change in a region that daily generates tons of greenhouse gases.
- Prevents landslides.
- Prevents soil erosion.
- Prevents floods into a valley that was originally a lake and still behaves like a lake
What are the threats to the water forest?
The Water Forest is menaced by several unrelenting trends:
- Urban sprawl on all fronts and from within
- Poor reforestation practices
- Loss of native grasslands and its wildlife: grasslands are not recognized as a valuable land-use
- Illegal logging associated either to poverty or to organized crime
- Soil extraction for gardens in the surrounding cities
- Land tenure conflicts
- Expanding agricultural frontier
- Overuse of dangerous agrochemicals
- Rampant chaos
What makes FUNBA’s work unique?
FUNBA is the founder and coordinator of the Water Forest Initiative, which in turn is the ONLY multisector coalition dedicated to creating a sustainable future for the largest natural area in the megalopolis of Central Mexico.
How big is the Water Forest?
Besides 23 million people, what other lifeforms depend on the Water Forest?
Mexico is the world’s 4th most biodiverse country, presenting the highest number of endemisms and ecosystems. The Water Forest presents Mexico’s highest number of endemisms. The Water Forest harbours 10% of Mexico’s flora and fauna species10% of its species are endemic: 325 species of plants and animals found nowhere else on Earth.It harbours 8 of Mexico’s 10 great ecosystems: coniferous forests, quercus forests, mesophilous forests, dry shrubland, native grasslands, deciduous tropical forests, riparian forests, aquatic vegetationIt houses 5 of Mexico’s 6 ecological zones: subhumid tropical zone, humid temperate zone, sub-humid temperate zone, arid and semi-arid zones, alpine zones.
How Are Indigenous Peoples Involved?
The Water Forest presents a multi-lingual, multi-ethnic mosaic. Since time immemorial, four ethnic groups populated the Water Forest mountains: TLAHUICAS, OTOMÍES, MAZAHUAS and NAHUAS. But today, due to multiple reasons to migrate, the Water Forest is also populated by TOTONACAS, ZAPOTECOS, MIXTECOS and many other indigenous groups.
The Water Forest itself is communally-owned by 191 agrarian nuclei comprised of these native groups settled in the region since before the late 1930s. The Water Forest Initiative is currently working with 10 Water Forest community-based organizations, representing the three watersheds that originate in the Water Forest, as well as the three states involved. These are the following:

Structural engineer Roma Agrawal arrives at the bank of the Thames, opposite the iconic Shard skyscraper, whose foundations and spire she helped design. The 72-storey building is the UK’s tallest. But Agrawal’s attention is fixed on a much smaller object that she removes from her handbag: a nail that she forged herself.
As she slides it between her fingers, she explains how little the object has changed since its invention 6,000 years ago. And, at the same time, how much it has changed the world.
“Nails cost almost nothing now, and they’re just rolling around in our drawers. But if I take you back some 400 years to Colonial America, nails were incredibly precious,” she says. “They were so expensive because Britain banned the export of nails to its colonies because it didn’t want the ones in the UK going anywhere else.”
The UK’s voracious appetite for nails – which artisans used in everything from constructing ships, to fastening roof boards to buildings, to fixing shoes to horses – ultimately led the US to develop its own nail industry.
American entrepreneurs built factories containing machines that could mass-produce nails at a rate of 100 units a minute by the early 1800s. Soon after, the US became a global competitor to the UK in the sector, teaching a valuable lesson about the risks of protectionism.
Starting small to tell a bigger story is the central point of Agrawal's book, Nuts & Bolts: Seven Small Inventions that Changed the World. It charts the history of the nail, string, wheel, magnet, spring, lens and pump.
Agrawal’s fascination with engineering began when, as a curious child, she broke apart crayons and ballpoint pens to see how they worked. She spent her early years in India, where teachers give great weight to science, technology, engineering and mathematics (STEM) subjects. So it wasn’t odd that she was, in her own words, “a maths and physics nerd”.
She became aware that others perceived her passion for the subjects as unusual when she moved to the UK to study for her A-levels and later to take a Physics degree at Oxford University. And when she subsequently specialised in engineering, she gained a greater awareness of being in the minority – to this day, only 15 per cent of engineers in the UK are female, although the figure is higher in the Middle East and Asia.
This prompts the question: what would she change to improve the balance? She answers without hesitation. “The culture of the workplace.”
“I would go on construction sites as a young engineer, and there would still be pictures of naked women on the walls. There was a narrative for a while that we, as minorities, needed to adapt to fit in. That we, as women or as people of colour, need to adapt to the workplace to thrive. Now we’re saying, hold on a second, why can’t the workplace culture be such that all our differences are embraced and that we can all thrive?”
Stone Age string
Writing Nuts & Bolts challenged Agrawal to question some of her own preconceptions as she delved into the origins of her selected inventions.
“String was probably the most surprising,” she says. “We don’t often think of string as being an engineering invention or a piece of innovation, but it has developed over hundreds of thousands of years from something we used to make clothes into something that now holds up bridges.”
By chance, archaeologists made a remarkable and unexpected discovery that string dates back to the Neanderthals while Agrawal was researching the subject.
“They only found evidence of this three years ago while I was writing my book,” she explains. “They found this tiny little piece of string in France that Neanderthals had created by twisting fibres from the bark of a tree.”
String’s Stone Age inventor remains unknown, but Agrawal uses her book to name and celebrate some of science and engineering’s other unsung heroes. From Stephanie Kwolek, who invented the bulletproof vest material Kevlar, to Josephine Cochran, who patented one of the first workable dishwashers back in 1886, to Indian scientist Jagadish Chandra Bose, a pioneer in wireless technology.
So would the world look very different if there had been more female engineers or those from more diverse backgrounds? Agrawal points out that many men had tried and failed before Josephine Cochran cracked the dishwasher.
“I always conjecture that is because men never wash dishes,” she laughs.
But on a more serious note, she is emphatic that all marginal communities need a voice in engineering. “Otherwise, you are not going to get the best solutions that work for everyone.”
Focusing on the lens
The most personal part of Agrawal’s book is the chapter on the lens, which begins with a letter to her daughter who was born via IVF. “I got to see you before you went into my body,” she writes. “You wouldn’t exist without a seemingly simple little curved piece of glass.”
She explains that the lens was part of a microscope that had let scientists create the embryo that became her child.
“Microscopes became a little bit of a fascination. And I basically tried to keep breaking all these complex pieces of technology down to the elements.
“By breaking things down, we can understand them better.”
And that is essentially the message of her book. By exploring the origins and impacts of seven small but critical inventions, we can better appreciate how they helped shape the world over centuries, sometimes millennia, and acknowledge the human endeavour involved.

Language is an important expression of people's own cultural identity and plays a key role in the field of literacy. What does this mean for literacy programmes, especially in countries with multilingual population groups? This paper (shortened version) will look at the shape of language issues as they arise in adult literacy work and will present some examples of how literacy acquisition is structured in a variety of multilingual environments in different regions of the world. While the author will refer necessarily to language policies in the school context, the focus is firmly on adult literacy and the language issues involved in pursuing the fourth EFA goal on increasing literacy rates. Clinton Robinson developed an interest in adult learning and literacy during ten years of NGO work in Cameroon, with a special focus on the use of African languages in development communication. More recently as an independent consultant, he has conducted studies and evaluations of a range of adult learning programmes in Africa and Asia. Currently he works as a member of UNESCO's Education for All (EFA) coordination team.
The international community has long recognised that language issues are central to the organisation and delivery of education of all kinds. The countries of the world manifest varying degrees of linguistic diversity, a reality that has become ever more widespread with the increasing mobility of populations. International declarations have gone beyond merely recognising language issues and have called for serious attention to be given to designing educational, cultural and, more broadly, development policies which enable people to make maximum use of the language resources at their disposal. In practice, this has most frequently entailed a plea for the effective integration of both local and international languages in learning programmes, as documented in UNESCO's presentation of principles for education in a multilingual world (UNESCO 2003).
The Dakar FrameworkforAction in its expanded commentary includes "the importance of local languages for initial literacy" as one of the factors of effective and inclusive education and refers repeatedly to the special needs of ethnic and linguistic minorities. Language is also seen as a factor in developing relevant curriculum, in ensuring quality learning and in respecting cultural identities. In the EFA movement, therefore, the case is clearly made for adequate consideration to be given to language issues in realising the Dakar goals. However, these intentions may or may not be reflected in national policy statements and are even more rarely translated into effective multilingual strategies in education on the ground. Where policies regarding the use of languages in education are spelled out, the emphasis is always on the context of formal schooling, as a national system. While different parameters apply in making decisions about adult literacy work, it is nevertheless a further sign of the relative neglect of adult literacy at both policy and implementation levels that the questions of language use in literacy promotion are not systematically addressed.
I take a plural view of literacy - 'literacies', as indicated in the title of the paper. This concept, whose dimensions cannot be explored here, defines literacy as embedded in context and focuses on the different practices and uses of literacy. In consequence, literacy takes a different shape in different communities and individuals, and indeed a single individual may use a range of literacies. With regard to languages, the plural view of literacy is crucial, since language itself is a factor which distinguishes one literacy from another, along with other factors such as mode of acquisition, institutional uses of literacy, the purposes and modalities of literacy. The generic use of the singular term 'literacy' in this paper in no way detracts from this fundamentally plural view. The notion of 'literacies' is well developed by Street (1995, 2001), Barton and Hamilton (1998) and Collins and Blot (2003), among others.
Literacy needs are distributed unevenly across the world with South and West Asia accounting for more than half of the world's non-literate population. Taken with Sub-Saharan Africa and the Arab region, this proportion rises to more than three-quarters (UNESCO 2004). In terms of languages, it is important to ask how far large literacy needs are related to levels of linguistic diversity and of language development. Language development refers to the current state of written development of a language - how far it is used in written form, what opportunities for literacy in the language exist and what kinds and amounts of text exist, in whatever form - printed, electronic, etc.
The language situations of countries with the highest literacy needs are very different. Taking the nine countries listed in the 2005 EFA Global Monitoring Report as accounting for the highest proportion of literacy needs, and the five countries with the lowest literacy rates, the numbers of languages are as follows:
country | Percentage of world non-literate population | Adultliteracy rate | Number of languages |
Nine countries = 70.3% of world non-literate population | |||
India | 33,8 | 81.3 | 387 |
China | 11,2 | 90.9 | 201 |
Bangladesh | 6.5 | 41.1 | 38 |
Pakistan | 6.4 | 41.5 | 69 |
Nigeria | 2.8 | 66.8 | 505 |
Ethiopia | 2.7 | 41.5 | 82 |
Egypt | 2.6 | 55.6 | 10 |
Indonesia | 2.3 | 87.9 | 726 |
Brazil | 1.9 | 88.2 | 192 |

These data indicate only at a very coarse level of analysis the relationship between literacy and linguistic diversity, showing merely that all these countries are linguistically diverse, but that this diversity varies greatly from one country to another. Nevertheless, even such basic facts may be ignored in discussions about literacy promotion, with language questions relegated to the level of implementation, rather than figuring in policy and planning fora.
In the above table, for instance, over 95% of the Brazilian population speak Portuguese, with the other languages of Brazil spoken by small and very small groups of indigenous peoples. Some of China's minorities number in the millions, although the Mandarin-speaking Han population represents 70% of the population. Much of the linguistic diversity of Indonesia is concentrated in three provinces - Irian Jaya (263 languages), Sulawesi (114), and Maluku (128). In Bangladesh, 98% of the population speaks Bangla, the national language. These observations do not minimise the importance of language diversity, but rather call for a more detailed analysis of each situation.
We should also guard against seeing the linguistic diversity of the five countries with the lowest literacy rates as a cause for their plight. Rather, the high linguistic diversity should be a reason for looking seriously at language as a material consideration in ensuring wider access to literacy and higher levels of acquisition and use. In other words, linguistic diversity should not be seen as an insuperable problem, but as a key factor in designing intervention in literacy and other areas of development. It is not unknown for linguistic diversity to be lauded as an important and valuable manifestation of cultural diversity, while being described in the same context as an impossible problem in terms of educational usage.
If data such as those in the above chart are to be of real use in understanding the situation with regard to literacy and languages then a range of other questions must be answered:
This kind of fine-grained analysis is rarely undertaken, and so data are hardly available to provide answers to these questions. While statistics are available for the population of minority linguistic groups, data on literacy rates within those groups are difficult to obtain, let alone a breakdown by the language of literacy. The fourteenth edition of the Ethnologue (Grimes 2000), a listing of the world's languages which aims to be complete, attempts to show literacy rates for a number of minority groups. Information is given in some cases on the literacy rate in their own mother tongue, together with the rate of literacy in a second language, such as an official or national language. The data are patchy and there is no indication how they were collected or whether further research will result in more accurate data or data for a wider range of populations. However, it is a research undertaking which is urgent and would shed considerable light on the real levels of access to and use of literacy among linguistic minorities and indigenous peoples.
Interestingly, the few data that the Ethnologue provides indicate that literacy rates in the mother tongue are equal to or, more commonly, lower than those in a second language. Data for both rates are given for very few languages, of which the following serve as examples from different regions of the world:
Language | Population | Literacy rate in own language | Literacy rate in second language |
Amele, Papua New Guinea | 5,300 | 25-100% | 75-100% |
Berom, Nigeria | 300,000 | 10-30% | 25-50% |
East Makian, Indonesia (Maluku) | 20,000 | below 1% | 20-30% |
Popoloca (San Juan Atzingo), Mexico | 5,000 | 20% | 30% |
Saraiki, India | 59,640 | below 1% | 15% |

The first example, Amele, gives a strong indication that a fully bilingual approach to literacy acquisition has been implemented and has been, thus far, effective. This represents the kind of result which gives best opportunity to minority groups: mother tongue literacy for initial learning, cognitive development, self-expression and cultural self-confidence, and second language literacy for participation and voice in the wider society. The other examples could be interpreted in radically divergent ways:
In order to assess which of these interpretations provides the best basis for further promotion of literacy, it would be necessary to carry out surveys of language use, bilingualism, the literate environment, and attitudes to language and literacy in the respective communities. It is precisely because such studies are hardly ever undertaken that inappropriate policies and ineffective strategies give rise to a succession of literacy initiatives which fail to take root or offer real opportunities of development.
According to Walter (forthcoming) the 4,500 linguistic communities of the world which have a population of less than 50,000 represent some 53.38 million people; these are the smallest linguistic groups of which several in the above table are examples. Walter comes to a similar conclusion about their prospects of access to literacy and education:
"From the perspective of literacy and education, this cluster of linguistic communities - some 53.38 million people - represents a compelling challenge. Realistically, apart from occasional exceptional efforts, most of these people will either be expected to achieve literacy in a second language or will be by-passed as "unreachable" given the cost of providing special programs for such small people groups. In either case, high levels of illiteracy will be the norm for such linguistic communities for the foreseeable future." (Walter, forthcoming: 19)
Walter's detailed analysis of literacy rates in relation to languages focuses on the status of the languages concerned. In very general terms, his work shows that lower literacy rates are not associated with linguistic diversity as such, but with the level of development of each language. Where a higher proportion of the population of a country speaks undeveloped languages (for instance, without an agreed
writing system) there are lower literacy levels. Walter is quick to point to anomalies and exceptions to this observation, emphasising that literacy rates depend on much more than language issues. These are one of a number of variables, which include policy issues and cultural questions. We now turn to these.
As Ager (2001) points out, language policy formulation is most frequently examined at the level of the nation-state in respect of the way that governments structure the use of languages within their borders. This results in giving languages a certain status, for instance as a national language, an official language, a provincial language or some other category. Policies are designed so that languages will be recognised as having a certain prestige or reach, that they will be used in certain ways (for instance in government administration or education) and that they will be learnt by certain groups of people, often with the intention that the whole population acquires a particular language.
Government policies in multilingual environments give differential status to languages, most often based on how extensively they are spoken. Thus in India, Hindi and English have national status, while fourteen other languages are given recognition at state level. This means that schooling is dispensed in those languages in the relevant areas, and that there is demand for literacy in them too. However, there are many more languages, including tribal languages. These are recognised as valid means of communication and learning and are given moral recognition, but no official support for their development or use in education. In terms of literacy acquisition, therefore, their use depends on local organisations and initiatives, as well as on community demand and support.
In countries with large numbers of smaller language groups, such as Cameroon (over 250 languages) and Papua New Guinea (about 850 languages), all languages are recognised but levels of support are very different. In Cameroon, the government's policy is that local languages can and should be used for initial schooling, but no attempt has yet been made to move towards implementation (there are some limited NGO initiatives), and the government's literacy efforts, minimal as they are, are conducted entirely in French or English, the official languages. It is only since the adoption of a new national constitution in 1995 that Cameroon has made official mention of its many 'national' (= indigenous) languages. Papua New Guinea evinces the boldest of any policy regarding language in education, with the possibility of using any of its many languages in primary schooling, given certain kinds of community support, for instance in the preparation of materials. Once again, this policy was developed for formal schooling specifically, not with adult literacy necessarily in mind.
Nigeria (505 languages) and the Democratic Republic of Congo (218 languages) are in a different situation again, with strong regional languages: Hausa, Yoruba and Igbo in Nigeria, and Lingala, Kiswa-hili, Kikongo and Ciluba in DRC. These are used, and promoted, as extensive lingua francas and are used in education, albeit somewhat patchily in DRC owing to collapsed systems (see also below 4.3). Other local languages may be used in education and literacy - policies allow for this - but in practice little or no support is given to such initiatives, which depend on community or NGO resources.
In practice, therefore, policies in multilingual situations tend to give status to a certain number of languages, but not all of them. Policies may specifically address the educational use of languages, as in PNG where there is still no explicit overall language policy. PNG is one of the few countries where the use of all languages is encouraged in education and it is certainly the most egregious example of policy-making, given the extremely high number of languages within its borders. Even where policies allow for the use of minority and smaller languages in education, such as in India, Nigeria or Cameroon, there is rarely any government support either in formal education or in literacy.
The former colonial polices of France and Britain had distinctive kinds of influence on the use of African languages (Brock-Utne 2000). The British approach of indirect rule led to a much greater space for local languages and their use was part of the relationship between colonial administrators and local people - special allowances were given to colonial officials who learnt local languages. The use of languages in education nevertheless fluctuated considerably over the years, but the policy allowed for adult literacy work using both African languages and English. This has resulted, for example, in university departments and research institutes focusing on adult learning, where language questions have been of long-term concern (e.g. Nigeria, Ghana, Sierra Leone).
The policies of French colonial authorities were quite different, with a concern to integrate colonial possessions into metropolitan governance structures and to promote French culture and language. French took a strong hold in the coastal West African states, so that, in many of them, it was only in the 1980s and 1990s that policies began to recognise African languages as valid vehicles of education. Government adult literacy programmes were overwhelmingly in French. In the Sahelian states, French was less well known, and so local languages had greater space, both in formal and non-formal learning; Senegal, Mali, Niger and Burkina Faso have, for instance, demonstrated high levels of innovation and experimentation in local language literacy (Brock-Utne 2000; Chaudenson and Renard 1999; Dombrowsky et al. 1993).
A focus on government language policy obscures the fact that much adult literacy work is conducted by non-governmental organisations, from local community-based groupings, religious organisations, development associations, to international NGOs. In many multilingual countries, such as Papua New Guinea, Cameroon, Burkina Faso and Peru, NGOs carry out the bulk of adult literacy efforts, and for the most part adopt multilingual approaches, beginning with literacy instruction through the local language and moving to the learning of a language of wider communication. Experiences of national NGOs in Cameroon, Uganda and Ghana are presented in section 4 below, as well as the work of a regional NGO in the Democratic Republic of Congo. The contrasting approaches of two international NGOs are presented here: ActionAid and SIL International.
ActionAid is a network of affiliated NGOs which undertakes a wide range of development activities. Adult literacy has figured prominently in its work, and it developed the Reflect literacy method (Archer and Cottingham 1996a). Its basic approach is to put the learning process in the hands of learners themselves, avoiding the prior preparation of materials or the use of instructional primers. With a strong emphasis on a facilitated group process, learners discuss their knowledge of health, economic, social and other aspects of their community's life, representing the output in charts and diagrams, often drawn on the ground. The literacy component consists of identifying key words, each learner writing them in their own books and collectively on charts, the idea being to create learning materials as they go along. Initial studies showed good learning outcomes as well as heightened community mobilisation (Archer and Cottingham 1996b). Thefleflecf method calls for free discussion among learners, and this occurs in the mother tongue. It is therefore this language which is used for initial literacy. In the Ugandan experience, the languages used were not written in the first instance and the Reflect process contributed to their development and to their possible use in formal education. This grassroots approach contrasts with governmental approaches and the top-down national literacy campaigns of the past. In language terms it builds on the way communities actually use languages and patterns learning accordingly. However, where the languages used are in an early form of written development, the question of developing the literate environment and producing ongoing materials remains to be answered.1
SIL International is an NGO which has initiated literacy and language development projects in hundreds of minority and indigenous groups around the world, based on a religious motivation of translating the Christian scriptures. In literacy, partnerships with government, other NGOs and communities have led to literacy programmes in languages hitherto unwritten (SIL 2003). Typically, the development of a language in written form, based on linguistic studies, is followed by the preparation of literacy primers in collaboration with local knowledge-makers/story-tellers/writers. These books are often the first to be produced in the language concerned, and little else may be available as people start acquiring literacy. Since many of the language groups where SIL projects take place are small, there is always a need for literacy in other languages; such instruction may be offered by the project itself or through other agencies. SIL's approach gives pride of place to the local language and emphasises its development in written form. As a linguistic, research-based exercise it is effective in enabling literacy and a literate environment to develop in languages otherwise neglected; however, it is less effective in integrating the resulting literacy use into the daily lives and concerns of individuals and communities. Although writing and the production of materials are in focus from the start, there is inadequate investment in identifying and reinforcing domains of literacy use. Such a heavy emphasis on the mother tongue, however necessary in situations of massive neglect, risks obscuring the absolute necessity of multilingual approaches to literacy for such groups.
In terms of policy-making, these NGO experiences, together with those in section 4, contrast greatly with government approaches. While the NGOs would not perhaps claim to be making policy, the reach and impact of both the international NGOs referred to above results in de facto policies on the ground, with influence on what governments find feasible and desirable. Further, a fundamental question with regard to language policies and literacy must be asked: how far do official language policies matter for the promotion of literacy acquisition among adults? There are several elements of response:
Kosonen's study (2005) of language policies and situations in education in east and southeast Asia is one of the few that presents data on language use in both formal and non-formal education - non-formal education includes both adult learning and primary level equivalency programmes. His survey of eleven countries shows that eight of them use local languages, thus a multilingual approach, in adult education - this is the same number as use local languages in the formal system, at least to some extent. He also notes that adult education is conducted principally by non-governmental bodies in five of the eight countries. This speaks for a strong correlation between government policies regarding formal schooling and the grassroots activities of NGOs and communities, in terms of approaches to selecting the languages of learning.
Approaches to literacy in developing countries are overwhelmingly instrumental - the focus is on how literacy and its acquisition will enable people to achieve improvements in their lives, defined in terms of socio-economic progress and better personal and family health. These sorts of aims underlie the functional approach to literacy. In this perspective, language is also considered from an instrumental point of view: which language(s) will best enable people to access literacy and the knowledge, skills and behaviours leading to positive change? These approaches and perspectives are fundamental to development and to a rationale for the value of literacy within it. They also emphasise the key communicative role of language and, depending on how fine-grained the analysis of context is, give due consideration to the complexities of choosing languages for literacy.
A focus on the functional value of literacy, with a corresponding emphasis on the communicative role of language, risks ignoring two key aspects: the cultural value of literacy and the symbolic function of language. Language has long been part of nation building, particularly in situations of high diversity where the promotion of a single language has been seen as a key symbolic means of national unity (Mansour 1993). However, such use of language as a symbol in the national political sphere can conflict with the affirmation of local, especially minority identities. In this respect, the language of literacy can exercise an important cultural function.
Literacy among the linguistic and cultural minorities of Myanmar has been promoted by various agencies, both in the national language, Burmese, as well as in the minority languages themselves, the latter entirely through non-governmental initiatives. Literacy among these groups is lower than among the Burmese-speaking population and there are very few materials available in the local languages. A survey in 2004 of the development and use of rural development information materials in local languages among the minorities showed that the newly produced development guides would certainly fulfil their functional role of generating new ideas, discussion and initiative within local communities. However, adults in these groups also consistently mentioned the cultural importance of having literature in their own language - the report states:
"The production process and use of guides have considerably raised people's perceptions of the value of their own culture and language, and lifted expectations of how they fit into the process of local development. This impact cannot be overstated for communities which have long laboured under the illusion that their language and culture are second-rate and incapable of shaping the modern world." (Tearfund 2004:27)
The link between the language of literacy and cultural identity is particularly important for minorities who are, or feel themselves to be, outside the social mainstream and who are constantly obliged to operate on someone else's linguistic terms. Language is one of the most obvious markers of cultural identity and frequently becomes the symbol and rallying cry of embattled cultural minorities. In many countries, it is the mainstream populations or elites assimilated to the mainstream who make decisions on language use in literacy and education. Although they may be sensitive to instrumental arguments regarding the use of minority languages for development purposes, it is rare that they will appreciate - much less act on - the symbolic and cultural value of literacy in the local language. There is in fact a disconnect in policy-making at this juncture, since linguistic diversity may well be lauded as part of the cultural heritage, but little or no effort made to draw out the implications for education or development (Robinson 1996). This is all the more inauspicious as the cultural basis for development is increasingly viewed as crucial in empowering communities to initiate and sustain positive change (cf Eade 2002; WCCD1995).
The adult literacy rate in Uganda is 68.9% (male 78.8, female 59.2 - UNESCO 2004). The Ugandan government estimates that there are 6.9 million adults without literacy skills. There are wide regional disparities, with literacy rates as low as 47% in northern regions, and as high as 77% in central districts. More than 40 languages are spoken (Grimes 2000), and English is the official language. The largest language group, speaking Luganda, accounts for less than 20% of the total population. Efforts to address adult literacy must therefore take seriously the question of which language(s) people should use for literacy purposes, both in initial acquisition and in ongoing application.
Since 1992, Uganda's policy on the use of languages in education has been that local languages should be used for initial literacy, both for children (at least the first four years of primary school, and up to seven) and for adults. For schooling, six languages were chosen at national level, but districts had the freedom to develop and use others. They were to set up District Language Boards, though it is doubtful whether any actually exist. Schooling also aims at competence in English, and demand from adults for literacy in English is strong. However this does not mean that literacy is necessarily offered through English in the first instance.
In many multilingual situations in Africa, planners often present language choices as either-or alternatives: either literacy in the local language or in the official language. The educational argument for using first the language which the learner knows best is frequently lost. This is not the case in Uganda, even though reference to language use is minimal in the government's published literacy policy (National Adult Literacy Strategic Investment Plan 2002), with a recommendation that literacy providers should "develop simple reading materials in English and local languages" (p.17). Decentralised government initiatives, often with NGO cooperation and input, focus on initial literacy instruction through the language of the learner, with progression to English once basic literacy competence has been achieved (EAI 2003). This separates the two quite distinct learning objectives: acquiring literacy, and learning a foreign language. The national literacy plan has not yet been implemented in a systematic way, but this may, paradoxically, have resulted in more appropriate, localised approaches to the use of Uganda's languages in literacy learning.
Bhutan, a small, landlocked country of 700,000 inhabitants wedged between the giants of China and India, demonstrates a vigorous pride in its distinct cultural heritage and national traditions. As it has sought to interact to a greater extent with the outside world over the last decades, education has been a key plank of its development policy. Since 1993 the government has run an adult literacy programme under its Non-formal Education Department to reach those who are unschooled or under-schooled; it has offered literacy instruction in Dzongkha, the national language, which is written in a Devanagari-derived script. The medium of instruction in the formal school system is English, with an emphasis also on a high level of literacy and other language skills in Dzongkha, which is promoted as part of national identity and culture.
Bhutan is, however, linguistically diverse with over 20 different languages (Namgyel 2003). Dzongkha is the only Bhutanese language which is used in written form and supported with government resources, being seen as a factor of national unity and a key marker of national identity. Non-formal learning programmes are currently all conducted in Dzongkha. The other languages of Bhutan are used in oral form, and some are closely related to Dzongkha - being from the same language family - while others are quite different. These languages are the daily means of communication for the groups speaking them, and not all have yet learnt Dzongkha. In 2003 the Bhutanese government estimated the adult literacy rate to be about 54% (Bhutan Ministry of Health and Education 2003), and noted that the "difficult mountain terrain, limited communication links and a dispersed pattern of settlement" were some of the reasons for lack of access to education. Given that these same, rather inaccessible communities also speak languages other than the national medium of instruction, the linguistic issue merits further analysis.
These different languages are part of the rich cultural diversity of Bhutan, and their development in written form may at some point take place-there is no restriction on such activities, although communities are not currently promoting their languages in this way. Nevertheless, for the purposes both of effective learning and cultural expression, the possibility of using these community languages in some more structured way in the future should not be ruled out, as part of the multilingual practices which already exist and which include Dzongkha and English, and as further development of Bhutan's cultural heritage.
In the north-west of the Democratic Republic of Congo (DRC), a local NGO, Sukisa Boyinga (Conquer ignorance), built on adult literacy work which began in the 1980s (Gfeller 1997). Centred around the town of Gemena, the majority of the population speaks Ngbaka, numbering over 2 million speakers. Other languages, such as Ng-bandi and Mbandja, are also spoken in the area. DRC has a total of over 200 languages, of which four serve as regional lingua francas:
Lingala, Kikongo, Kiswahili and Ciluba. In the Gemena region Lingala is the language used for communication between different language groups; in addition, French, the official language, is used for administrative and government purposes. From the start, Sukisa Boyinga launched literacy activities based on the mother tongue, Ngbaka, but gave attention to the full range of languages which people use in their daily lives. Thus the programme also introduced literacy in Lingala and French, through the medium of the learners' first language.
The initial aims of the programme were basic literacy in Ngbaka and Lingala, with an introduction to oral French. This was structured in three levels:
Level 1: initial literacy and numeracy training in the local language. At this stage knowledge is applied to everyday life by reading a health book after the basic skills have been taught.
Level 2: basic complementary training to reinforce level 1, and a first introduction to literacy in Lingala. A reader of local folk stories is also used.
Level 3: applied local language literacy; topics include animal husbandry, agriculture and elementary book-keeping; more advanced training in Lingala; initial oral French, with an emphasis on its use in practical everyday situations; further arithmetic.
These literacy, numeracy and language-learning goals were later expanded, at learners' insistence, to a full adult education programme which would offer the equivalent of primary schooling. The gradual deterioration and eventual collapse of the government schooling system meant that very few adults had completed primary school - in the mid-1990s about 90% of adults in this region did not have a primary school leaving certificate (Robinson and Gfeller 1997). The Sukisa Boyinga programme therefore offered the only opportunity for structured learning in the region. A further three levels were added to the programme, using Ngbaka as the medium of instruction and increasing skills in the other two languages:
Level 4: further Lingala reading; French grammar;geography from a local perspective; further arithmetic.
Level 5: further Lingala reading; further French training; history from a local perspective; further arithmetic.
Level 6: French training to cover the remaining areas of the DRC national primary school curriculum; political systems of the world; creative writing.
By 2000, a total of 46,400 adults were enrolled in this programme, with over 2,500 trained facilitators. In addition, the first three levels of the programme were adapted for children's schooling, with 6,000 children attending 50 primary schools and 12 community schools (SIL2001).
Apart from the fact that this initiative filled a gap left by the collapse over many years of the regular school system, the extent and the effectiveness of this programme have a clear linguistic dimension. In this region of DRC, people habitually need to use, and do in fact use, three languages: their own for all purposes of daily communication among their own families and villages, a regional language for wider contact and travelling further afield, and the official language for contact with the government. In practice, the local language is the most widely used, Lingala is known and used to varying degrees depending on individual needs and circumstances, while French, the official language, is known and used by only a few. Desire to learn French is, however, high. Thus the design of the literacy and adult education programme is patterned after the way people actually use languages, and a three-language approach is in no way difficult or burdensome as an educational strategy as far as the learners are concerned. On the contrary, the approach is entirely natural and obvious as it builds both on existing linguistic knowledge and on the demand to access new language resources - literacy in Ngbaka, enhancing oral Lingala and adding literacy in it, and oral and written French. It is also noteworthy that the language of instruction and interaction in the programme is Ngbaka throughout. This means that even when material is presented through other languages (for instance, by means of a development manual in French), it is explained and discussed through the language which learners know best and - more importantly - in which they will apply new knowledge to their daily lives. Undertaken in the most inauspicious circumstances of deprivation and conflict, this programme provides a model of a fully integrated multilingual approach to literacy and adult learning.
Ghana's policy on the use of languages in education has shifted back and forth over the years, sometimes emphasising the role of Ghanaian languages in initial learning, sometimes stressing the need for all to learn English, the official language. Ghanaians speak over 60 local languages, of which fifteen have official status as languages to be used in education, both formal schooling and adult literacy. Local communities, NGOs and others are free to use any Ghanaian language in development programmes, including adult literacy. One such project, undertaken by a local NGO, took a bilingual approach in some 22 different language communities, offering initial literacy in the local language of each group, with subsequent learning of English; local-language literacy was focused on functional uses such as micro-credit and income generation, women's empowerment, and the exercise of human rights. Only six of the 22 languages were among the fifteen accorded official status, and all 22 had established writing systems only within the last 30 years. Reporting on learners' own assessment of the benefits and impact of literacy acquisition, the project evaluation drew up the following list of responses (SIL UK 2004):
This list is fascinating for the high level of importance given to the interaction between literacy and language, both the role of the local language and access to English. The reason at the head of the list - "write their own language/mother tongue" - was a very frequent response, and seems at first sight to be a superficial and almost circular comment, adding little to what we already know about literacy. However, it is a most significant remark in a context where the local language was unwritten until a few years ago and where schooling and other forms of learning systematically scorned its use, until very recently. A principal value of literacy and motivation for taking part in literacy groups is the possibility to use one's own language in written form and for learning purposes, thus putting to one side the barrier of having to learn and adopt someone else's language and, to a certain extent, someone else's culture and ways of thinking. This response may be taken as an expression of many different emotions, ranging from relief to pride, from cultural self-assertion to joy in learning.
Lest anyone should conclude from these observations that the literacy programme fostered ethno-linguistic exclusivity, the last two listed reactions should also be noted. The vast majority of learners wished also to learn English - thus communities expressed their desire both to use their own language and to learn English, as the language of wider communication, of broader opportunities and (in the national context) of political power. These views coincide with those of many, in Africa and elsewhere, who daily use a number of languages - a multilingual approach to learning is the only appropriate way forward.
There are interesting consequences for the local implementation of language policies in schooling from this project. As the government shifts its position on the languages of schooling from time to time, based on political criteria, another dynamic is at work at the grassroots. In some communities, parents who have participated in adult literacy in their own language have pressured the school to organise local-language literacy classes for their children, as part of the regular timetable or in addition to it, making schooling a bilingual process. In many cases the trained facilitators working with adults also teach the children, since the regular teachers may or may not have the skills for mother tongue instruction. Thus the use of languages in adult literacy acquisition has had an influence on children's schooling; parents wish their children to enjoy the functional and cultural benefits of multilingual literacy - local language + official language - once they have experienced them themselves.
Cameroon has been described as one of the '"linguistic shatter zones" of the world, with over 250 distinct languages and a population of about 15 million. Grouped in three major linguistic families - Bantu, Adamawa and Chadic - the largest language community numbers less than 20% of the total population (Skutnabb-Kangas 2000), with the implication that some communities are very small, numbering perhaps 2000 speakers. In addition, Cameroon has the further complexity of using two official languages, French and English, a legacy of its divided colonial history.
Since independence in 1960, the debate has raged about how to use or integrate Cameroon's languages into national life, in particular as part of education. Without tracing here the vagaries of Cameroon's language policy and use over the years (cf Robinson 1996), suffice it to say that it was only in the 1990s that official pronouncements and legal provisions opened the way for the use of Cameroonian languages in formal education. Although still not fully generalised, a well-tested model of bilingual education is now in place in over 300 primary schools, serving more than 340,000 pupils. The system, known as PROPELCA,2 enables children to start their education in their own language and then learn one of the official languages, transitioning to use the latter as a medium of instruction by the fourth year of primary education. These developments raised the profile of using Cameroonian languages for adult learning also.
In fact, local languages had always been used for adult literacy, although not by the government, which only ran programmes in the official languages. However, local and international NGOs, churches and missions worked with individual communities to develop their languages for use in literacy. The question, however, arose as to how such work could be planned on a broader basis and made available to the many language communities of the country. What kind of programme could cater to the multilingual literacy needs of so many different languages and groups? In Cameroon the answer to these questions, as far as adult literacy is concerned, has been to devolve responsibility to the communities themselves. Thus language committees came into being at community level to stimulate and supervise literacy activities. These receive support from the National Association of Cameroon Language Committees (NACALCO), a national NGO which offers training in all aspects of adult literacy and some funding for the production of materials. Currently 76 language committees are affiliated to NACALCO. In addition, NACALCO staff provide training for teachers in PROPELCA schools. In addition to selecting teachers and organising adult literacy classes, local language committees are expected to:
A key part of the philosophy of this approach is linking adult literacy with the local environment. Where PROPELCA schools operate, links between formal and non-formal learning are possible, bringing adult and child learners together. Language committees forge links and develop cooperative writing/publishing projects with NGOs in development areas. Writing competitions are organised for the promotion and celebration of local knowledge and culture. Along with these activities go classes offering transition to literacy in one of the official languages.
Like many NGO initiatives, NACALCO has focused on promotion of adult literacy on the ground, with little documentation or dissemination of its experience or lessons learned. Its approach of devolving responsibility in a zone of high linguistic diversity has clear connections with questions of decentralisation and local management. It also offers insights on how the local context can be fully respected and used in education while at the same time moving beyond the merely local towards a national, scaled-up approach. In the light of these connections with crucial EFA questions, it is unfortunate, even surprising, that since Dakar funding for this initiative has become less available, with one of its significant projects - enabling 20,000 adults to acquire literacy each year - coming to an end in 2003 (NACALCO 2005).
A number of more general issues arise out of these case studies, and these are highlighted here. Each issue is the subject of research in its own right; however, their dimensions are sketched here briefly to indicate how fundamental and far-reaching language questions are in the pursuit of adult literacy.
Languages and adult learning: Why is the language issue of importance specifically in adult learning and literacy? It is axiomatic in adult education that adults bring considerable experience and life knowledge into a learning experience and that any learning process should both recognise and build on this. In terms of language resources, adults bring a knowledge of their own language and the culture it carries, as well as possibly knowledge of other languages. While this knowledge may not yet extend to the written use of any of these languages, their oral command makes literacy learning a matter of adding new ways of using their linguistic resources. The question of learning new languages is different and is dealt with below. Since adult literacy programmes are frequently best structured as part of a wider learning process (new knowledge, skills, behaviours, etc.), using the existing knowledge of adults is key to relevant learning - this knowledge is transmitted through certain languages in each context, and so these languages must be part of the learning process.
Status of languages: Such is the prejudice of certain elites and groups that in some situations a language is defined as a language because it is written, condemning unwritten languages to an inferior status - often not as languages, but as dialects. Colonial authorities in francophone Africa (itself a telling phrase!) dubbed African languages patois, while in the Arab region, only modern standard Arabic has any status. The everyday Arabic varieties, quite different from the standard variety, remain unwritten and are considered deformations of the real language. Concern to make language a symbol of national unity leads the Bhutanese population to see other languages as inferior or as mere dialects, although they are in fact languages in their own right. In terms of literacy acquisition and the definition of what being "literate" means, it may therefore be that only one kind of literacy is recognised as such, in a particular language - literacies in other languages may not be considered worthy of the name.
Orality and literacy: In the past much was made of distinctions between oral and literate societies, in relation to their structure and development. Detailed studies of the many literacies found in different societies, as well as of communication practices, generally have shown that there is in fact a continuum of oral and literate practices (see Collins and Blot 2003). Both orality and literacy are strategies of communication which are deployed in various ways and to varying degrees in particular contexts; thus they stand in symbiotic relationship to each other, not in contrast or opposition. These insights also do away with the notion that some languages are inherently more suited to literacy or to certain kinds of thought than others - it is only a question of language development and language planning, not of the nature of languages.
Literate environment: the concept of the literate environment is a useful way to bring together all aspects of literacy: acquisition, use, materials, practices, media, institutions, purposes and languages. As the various case studies above show, multilingual literacies are frequently promoted by NGOs with little active government support. Where people acquire literacy in minority languages, the literate environment is often quite weak in that language with the result that there is little scope for use and little material in that language. A lack of concern for the whole environment in which literacy is acquired and used can thus undermine literacy efforts and offer learners little chance of using literacy to improve their life. Even in monolingual areas where literacy is in the language of the majority and where literate environments are relatively strong and dynamic, it may be that deficiencies of teaching result in the lack of useable literacy skills; this emerges as a brake on development so that people are not fully able to take up learning opportunities in other skill areas. This was evidenced in an adult distance learning programme in Mongolia and has echoes in Bangladesh. The lack of analysis of the literate environment and the neglect of a particular aspect of it, including language, is yet another factor in reducing development opportunities, or providing opportunities that cannot in fact be taken up.
Languages and the acquisition of literacy: The language question in the acquisition of literacy is complex and involves the purposes and practices of literacy, the pedagogies and materials of learning, the institutional frameworks and the sociolinguistic context. I look here at only two issues: bilingualism and language learning. There persists a myth in some quarters that acquiring literacy in one language reduces the chances of acquiring it satisfactorily in another: thus to acquire mother tongue literacy may be seen as a brake on acquiring literacy in a more widely used language. A further myth, less widely held today, sees bilingualism as subtractive - learning another language reduces capacity in the one already known. In fact, the opposite is the case: bilingualism is additive, and this applies to 'biliteracy' also, as some term it (cf Hornberger 2003). As the DRC study above demonstrated, the use of three languages in adult literacy was entirely natural, in terms of the way people use languages, and appropriate in terms of the broader socio-political context. Provision and organisation of multilingual literacy acquisition is seen as expensive and complicated only by those who do not experience the daily reality of operating in a number of languages - it is the norm for most people in the world.
The second issue is the confusion between literacy acquisition and language learning. In multilingual settings, for example in the Ugandan case above, the demand for literacy may focus on acquiring literacy in the language of power, English or French in Africa for instance. However, the learning processes to acquire literacy are different from those involved in learning a second language. Thus these two processes should be handled separately. Again, as the Ugandan example shows, it is better to acquire literacy first in a language the learner already knows well - their own mother tongue - before embarking on learning another language. In this way, the business of learning the second language does not have to deal simultaneously with literacy acquisition. Where literacy is only offered in languages that people do not know or know only a little, the outcome can be that neither good language skills nor good literacy competence is achieved.
Languages and materials: A complaint of learners in literacy programmes is often that there is nothing to read, or nothing of interest to read, once they have completed a literacy course. In contexts of a mainstream language, this may be due to unaffordable print materials, lack of availability, poor distribution, or institutional control of what people should read. In minority language contexts, it is frequently due to the paucity of materials - there simply is very little to read in the minority language. This evinces once again a neglect of the overall literate environment. It also points up the need to stress writing as much as reading; every community has potential authors, and a literacy programme should aim to dispense writers' training as an integral part of literacy acquisition. Whether in a mainstream or minority language context, literacy use will only be sustained where the literate environment is dynamic and constantly restocked. Most literacy programmes in the context of development focus on functional materials, forgetting that part of the motivation for using literacy is learning what is going on locally and elsewhere, as well as reading for leisure and amusement. This calls for an emphasis on ephemeral literature, alongside more functional and durable materials.
Languages and the governance and management of literacy work: It is increasingly recognised that literacy programmes should be organised locally, with full recognition of the local context; this implies attention to how programmes can be managed locally and what kind of governance structures would be most suitable. In multilingual settings, the need for local management and input is compelling, given the need to connect with the surrounding sociolinguistic environment and to introduce local knowledge and culture. Working with knowledge-makers and guardians of tradition will only happen when responsibility for the content of learning lies with the local community. The language committees of Cameroon illustrate how these aspects of literacy programming can be brought together and what kind of support they need. It should be said too that management of this kind is best carried out in the local language, further fostering links between learning and the wider socio-cultural development of the community. In fact, the language issue raises much wider questions for decentralisation processes in multilingual and multicultural contexts: how can social development be conceived, managed and sustained locally with local consultation and input and with full consideration of cultural realities? Communication in the languages of the people is a sine qua non which is routinely ignored.
To conclude, it should be clear that policy formulation should follow the needs and patterns of language use among communities, with particular attention to the way that minorities structure their use of the language resources available to them. This means articulating and implementing multilingual policies in a thoroughgoing way. Skutnabb-Kangas (2000) is a committed proponent of multilingual approaches to education and of the need to give attention to the languages of minorities and she points out that
"a single language of literacy succeeds only in countries which have a very large majority speaking that language either as their native tongue, or as a really well known lingua franca." (p.598)
Most countries - and certainly most developing countries - are highly multilingual. To look at the obverse of the coin, lack of a clear multilingual policy with respect to education results in the following negative impacts (the list is not exhaustive):
Clearly only a policy which provides for the use in learning of the languages people use in daily communication will avoid these negative consequences.
Even where there may be agreement in principle, objections to multilingual policies are often articulated, both by governments and by local communities; four of the more frequent objections are assessed here:
A multilingual policy will have the following key features, implemented in ways suited to local context:
These issues and concerns are far-reaching - this is no surprise in view of the central ity of language: it is both the essential means of communication (the lifeblood of learning and social development), and a key marker of identity. Unless multilingual policies are designed and implemented in multilingual situations, it should be no surprise if communication fails and languages become rallying points for increasingly strident cries for the assertion of a distinct identity.

In 2002, big dreams were infectious in this small manufacturing city where the Wasatch Mountain Range provided the backdrop of some of the ski events of the Olympic Games.
That year, educators in Ogden’s schools set their sights high as well, when they turned to a federal grant program to transform reading instruction and student achievement in low-performing schools.
But officials envisioned a broader goal for the 12,300-student district, with its growing Hispanic population and widespread poverty. If they were going to make a commitment to improve reading, they would have to spread the Reading First model—including intensive professional development, research-based instruction, and monitoring of student progress—beyond the four schools participating in the initiative to all K-5 classrooms.
Over the past several years, schools in this manufacturing and tourism hub have dramatically changed how they teach reading, and built a more knowledgeable teaching corps in the process. Steady improvements in student test scores—and a dramatic leap at two schools—have followed.
“The superintendent said that we will only apply for this grant if part of our time is spent on dissemination of the Reading First model to the other schools in the district,” Greg Lewis, the district’s Reading First director, recalled recently. “I’ve been involved in a lot of reforms, but they never made any difference in the classroom. But now instruction has changed, and, not surprisingly, performance has changed.”
Reading First was approved by Congress in 2001 under the No Child Left Behind Act to bring scientifically based reading methods and materials to struggling schools. The $1 billion-a-year initiative has been plagued by controversy over how it was implemented by federal officials and consultants, including charges of interference in state and local decisionmaking and of favoritism toward certain reading programs. (“E-Mails Reveal Federal Reach Over Reading,” Feb. 21, 2007.)
The program has found favor, though, in many of its 5,700 grantee schools. While the grants go to districts only for specified schools, the federal initiative allows states and districts to use part of the funding to provide training in the Reading First model to teachers in all schools.
A federally commissioned report and a 2006 survey by the Washington-based Center on Education Policy found that Reading First schools are devoting more time to reading instruction, conduct more substantive professional development in the subject for teachers, and are more likely than nonparticipating schools to use assessment results to inform instruction.
Those changes are evident in Jenny DeCorso’s 2nd grade classroom at Gramercy Elementary School, where rows of desks have been replaced with tables for small-group instruction, shelves are stocked with books sorted by genre and reading level, and centers allow students to tackle a variety of literacy activities designed to build their fluency and comprehension.
Lessons are punctuated with explicit and carefully sequenced skill-building drills, and opportunities to practice what students have learned. Vocabulary words such as “strategy” and “unexpected” are posted on the window next to a cover illustration from the latest book selection, Annie and the Wild Animals. Punctuation rules and other writing conventions adorn the walls.
Ms. DeCorso, an 11-year veteran of teaching, remembers when she and her colleagues each followed their own daily plans for teaching reading, and struggled in solitude to figure out how to reach students who weren’t learning from them. “We closed our doors and did our own thing,” she said.
“It used to be more commonplace to have kids who could read nothing when they came to 2nd grade,” she added. “Now, there are only a few who can’t read at this point.”
Of the 435 students at the school, more than half are Hispanic, and 87 percent are poor.
After completing a number of graduate courses in reading—a requirement for teachers in Reading First schools here—Ms. DeCorso says she is now more knowledgeable about how to teach the skill, and better equipped to carry out the structured curriculum and to provide supplemental lessons where needed.
She and the other 2nd grade teachers meet regularly to refine lessons, share insights and strategies for helping struggling readers, and analyze data from regular student assessments. On a recent Tuesday morning, a reading expert from Utah State University observed the teachers at work, as he does at schools here each week, and gave detailed feedback on how well their lessons and classroom structure reflected research on effective practices. The critique, while harsh at times, prompted the teachers to justify their approaches, or hash out how to improve them.
In the 2nd grade classroom next door, Shannon Cook follows a similar structure as other teachers here for the three-hour reading and language arts block each morning. In one corner, Ms. Cook sits with just a handful of her 25 pupils, helping them pronounce in rapid succession words with the “long e” sound, a lesson out of Harcourt Trophies, the text used in Reading First schools here. She holds up a slick card with an illustrated eagle and turns it over to reveal the spelling as the children say the word in unison. Next is a leaf, then a bead.
It’s evident that all five pupils can decode the words, and have grasped the sound. They move on to a poem and highlight words with the “long e” sound in a clever verse. They complete several other related activities before Ms. Cook, who is in her third year of teaching, calls together another group to work on a more challenging set of drills.
In the far corner of the room, several pupils are getting a quick course of phonics drills from a teacher’s aide.
The rest of the children are working diligently at the literacy centers set up around the room. Lissete Landaverde is sorting cards with words that include the “long e.” Monica Sanguino is finishing a popular chapter book before she answers questions about the author she has been studying, and Alexia Lopez is thinking of descriptive words to include in her story about her favorite summertime memory. Other students are sitting on the floor with headphones for a listening exercise.
“I read really well,” said Ibrahim Njie, who looked up from the story he was writing to boast about his improving fluency. “I’m reading faster than ever … 95 words a minute the last time I went to computer lab.”
Teachers in Ogden have that kind of information, and other data, at their fingertips and receive continuing advice on how to use it to target their lessons to students’ individual needs.
• Ninety minutes of the K-3 school day is devoted to the Reading First program. An additional 90 minutes for language arts is used for small-group intervention, oral language, and writing.
• The Harcourt Trophies reading program is the core curriculum. Teachers use approved supplemental and intervention texts.
• All teachers in Reading First schools have received a reading endorsement after completing graduate-level classes in reading. Many are pursuing a master’s degree in reading. Graduate classes are offered at the district’s headquarters.
• The reading time block includes small-group instruction for K-3 pupils, with skills-based lessons geared to each group’s reading level.
• A teacher’s aide leads intensive scripted lessons in phonics and word recognition to help students build foundational skills. Teachers work with the lowest-performing students.
• Classrooms include centers where students do literacy activities designed to strengthen reading and writing skills. The centers promote reading different genres, writing, listening, studying antonyms and homonyms, learning letter sounds, and reading science and social studies texts.
• Teachers give regular assessments—including Dynamic Indicators of Basic Early Literacy Skills, or dibels—to students to determine reading strengths and weaknesses.
• A reading coach at each school meets with grade-level teacher teams each week to review data and discuss instructional strategies and materials for addressing students’ needs. The coach visits classrooms to demonstrate lessons and to advise teachers on how to improve instruction.
• A Utah State University consultant visits the district three times a month to offer technical advice, critique classroom instruction, and help teachers apply research findings to practice.
• The district is disseminating the Reading First model to other schools in the district through a state-financed program called Performance Plus.

During planning time at Dee Elementary School, for example, the 2nd grade team held its weekly meeting with reading coach Margaret Young to analyze test scores and figure out which specific skills students were having trouble mastering.
Those sessions have helped teachers pinpoint pupils’ weak spots and find better instructional strategies for strengthening their skills. Teachers at this school, which until recently was rated as the most challenged in the state, never had Olympic-size dreams before. Their goals for raising reading proficiency, however, are no longer considered unattainable.
“During my first year here at a parent-teacher conference, I had no clue what to tell the parents. I had no data about how they were doing,” said Stephanie McGaughey, who has taught at the school for eight years. “Now, I can show them where their child is compared to the class average and benchmarks, and explain why we are concerned about their progress.”
Before she attended the reading classes and workshops through Reading First, “I just taught the children the same way,” Ms. McGaughey added. “If they got it, they got it; if they didn’t, I still moved on.” Now, she said, she has an arsenal of strategies for helping each student master all the essential skills, and support from a coach to help her use them.
Throughout the district, teachers are drawing on the lessons learned at the Reading First schools to improve instruction more broadly. A state-sponsored initiative, Performance Plus, allows the district to offer some of the same professional development and support services to the schools that aren’t part of the federal grant, albeit with a fraction of the funding.
Convincing administrators and teachers of the benefits of the voluntary program has been a hard sell at some schools, according to Reed Spencer, the district’s executive director of curriculum and assessment. Some 80 percent of the 125 teachers in the district’s non-Reading First schools have signed on to the program, which requires that they attend workshops and classes after school hours and on weekends.
But now, all teachers are bound by contract to adhere to the principles of effective instruction outlined in the Reading First plan, whether they’ve participated in the additional training or not. That means they are expected to teach, explicitly and systematically, the five components required of grantees’ programs under the federal law: phonemic awareness, phonics, fluency, vocabulary, and comprehension. In addition, the state directs them to develop students’ oral-language and writing skills, as well as several other areas that influence reading comprehension.
“We reserve the right to speak to any teacher at any moment about the explicitness of their instruction. That’s a direct outgrowth of Reading First,” said Mr. Spencer. “And principals understand that they can’t supervise things that they don’t know about.”
Principals and reading coaches throughout the district get the grounding they need in monthly meetings and periodic workshops that focus on effective instruction, assessment, and classroom observation. Administrators from Reading First schools meet as a group each week to update one another on how the program is working.
Reading First schools are making progress as judged by achievement-test results.

The intense focus on reading instruction is paying off in improved results on tests, Mr. Lewis said. And last school year, all of the Reading First schools met goals under the No Child Left Behind law for adequate yearly progress in reading for the first time.
Teachers here are celebrating those gains. But the proof of the program’s impact, they say, is in the day-to-day changes they’ve seen in their own practice and in children’s achievements in the classroom.
“I never thought a kindergartner could go beyond letter recognition, but now we’re seeing them read,” said Melissa Brock, a veteran kindergarten teacher at Bonneville Elementary School, where nearly half the 450 students are Hispanic, and 80 percent qualify for free or reduced-price lunches. Full-day kindergarten has given Ms. Brock and her colleagues more time to build a foundation for reading. Reading First, she said, has introduced a sounder instructional approach.
“Before, I was kind of flying by the seat of my pants,” she said. “Now, I actually feel more competent and capable as a teacher.”

The New Science Of Using Protein To Build Muscle - Menno Henselmans
06 Jun 2024 (6 months ago)
How Much Protein Can Your Body Absorb? (0s)
- The myth that the body can only absorb 20 grams of protein per meal is false.
- The body can easily digest and absorb large amounts of protein in a meal.
- The limit to muscle protein synthesis is called the muscle full effect.
- Whey protein, a rapidly absorbed high-quality protein, maximizes muscle protein synthesis at 20 grams in resting conditions.
- Mixed meals, slower-digesting protein sources, and post-workout conditions increase the productive amount of protein per meal to 40-80 grams.
- In rare cases, consuming 100 grams of protein in a single meal may be beneficial if it's the primary meal of the day.
- The body adapts to using protein when there is a demand for muscle protein synthesis.
- Muscle protein synthesis has a ceiling that can be raised through exercise, protein scarcity, and androgen levels.
- mTOR, a master enzyme, integrates signals for protein synthesis and determines the body's need for muscle growth.
- An acceptable protein target per meal for moderately hard training individuals is 20-40 grams of high-quality protein.
- Distributing protein evenly over at least three meals per day is recommended.
- Sandwiching workouts within a 5-hour intermeal window optimizes protein utilization.
- Consuming protein after a workout and during the period between the workout and sleep is crucial for muscle growth.
How Much Protein Do We Actually Need? (5m10s)
- The optimal protein intake for maximizing muscle growth is approximately 1.6 grams per kilogram of body weight per day.
- Protein intake above this point does not provide additional benefits for muscle growth.
- Consuming excess protein can contribute to fat gain due to its caloric content, but it does not directly convert to fat.
- Protein shakes and supplements can be useful for individuals who struggle to meet their protein goals through food alone.
- Increasing protein intake to 1 gram per pound of body weight can make a substantial difference in muscle building, especially for individuals who are not hardcore gym-goers.
- Incorporating fattier foods and even cheese as protein sources can help increase protein intake without sacrificing taste or variety in the diet.
The Protein Placebo Effect (10m45s)
- Expectation and belief can significantly impact physiological responses and performance, as demonstrated in studies involving fake steroids and the nocebo effect with gluten intolerance.
- Genetic predispositions can be overridden by expectations, as individuals have outperformed based on their beliefs rather than their actual genetic makeup.
- Brand perception and expectations can influence the perceived effectiveness of medications, even when the actual composition is the same, as seen with Red Bull's unique taste and its association with medicinal properties.
- Some products, like Parodontax toothpaste, deliberately have unpleasant tastes to create an association with natural and effective remedies, leading to initial success before consumers prioritize enjoyment over perceived benefits.
Thoughts on Flexible Dieting (18m16s)
- Flexible dieting emphasizes macronutrients and total energy intake for fat loss but may overlook fiber, protein type, and micronutrients.
- Calorie tracking is not sustainable for long-term healthy eating.
- A balanced approach is needed, considering both theoretical knowledge and practical sustainability.
- Sustainable diets, such as paleo, provide better food choices and satiety, leading to long-term success.
- Backloading and skip loading are practices of consuming carbohydrates at specific times to maximize carb intake and reset the metabolic rate.
Is Caffeine Effective for Building Muscle? (24m18s)
- Caffeine primarily aids psychological performance and has limited long-term effects on muscle gain, fat loss, or strength.
- Caffeine's benefits are more noticeable in sleep-deprived individuals, in the morning, and in those who are less well-trained.
- Excessive caffeine intake can disrupt sleep quality, leading to a negative cycle of increased caffeine consumption and worsening sleep.
- Pre-workouts have not significantly advanced since the early 2010s, and anhydrous caffeine (caffeine powder or pills) is often as effective, if not slightly more effective, than pre-workout supplements.
- Pre-workout supplements may have negative interactions with caffeine, creatine, citrulline, or beta-alanine.
- Coffee or Red Bull can be effective pre-workout options.
- Caffeine powder is the most cost-effective and accurate way to consume caffeine.
- Fat burners are generally ineffective and may have negative side effects.
- Fiber supplements can aid in fat loss by reducing appetite and food intake.
The Importance of Optimising Appetite (31m23s)
- Hunger is a fundamental principle that influences food intake, and palatable, calorie-dense foods contribute to modern weight gain and health problems.
- Fiber helps fill up stomach space and reduce overconsumption of calorie-dense foods, while protein helps fill up appetite units and aids in satiety.
- Meals should include a protein source and a low-calorie filler like vegetables.
- Long-term sustainable fat loss diets can be achieved without constant calorie tracking, but calorie awareness gained from tracking macros is beneficial for creating a sustainable meal plan.
- Time blocking and sleep tracking are important for productivity and understanding sleep patterns, and sleep tracking devices align well with natural waking and feeling refreshed as indicators of good sleep quality.
- Optimizing happiness, sleep, and productivity can be counterproductive, as applying pressure to oneself to achieve something can induce stress, making the achievement of that thing harder.
Sleep’s Impact on Fat & Weight Loss (39m2s)
- Sleep has significant effects on fat loss and muscle growth.
- Sleep restriction can reduce fat loss by over 50% and double muscle loss.
- The effects of sleep deprivation are more pronounced during weight loss diets.
- Sleep deprivation and stress may have a negative interaction effect, further impairing sleep quality and increasing adverse responses to stress.
- Lack of sleep can affect diet adherence, leading to overeating and preference for unhealthy foods.
- Poor sleep quality can negatively impact training performance and overall results.
How Safe Are Artificial Sweeteners? (42m54s)
- Artificial sweeteners are generally safe and effective for weight loss and do not negatively impact the microbiome.
- The potential risks of artificial sweeteners should be weighed against their benefits, such as improved diet adherence and satisfaction.
- Intermittent fasting (OIC) appears to have fewer risks compared to obesity.
- Artificial sweeteners do not manipulate brain systems, but humans can develop a preference for sweet tastes regardless of the source.
- Sweeteners can alter taste perception and increase the preference for sweet foods, so adding them to vegetables is not recommended.
- Sweeteners can enhance the taste of certain dishes like pasta and tomato soup by increasing their sweetness, especially when using high-quality tomatoes.
Does a High Protein Diet Impact Longevity? (49m43s)
- High protein diets have significant health benefits, including fighting sarcopenia, reducing diabetes risk, and providing other positive effects.
- Concerns about mTOR activation and negative effects of high protein intake are generally exaggerated, as most long-term studies do not find a significant relationship between protein intake and all-cause mortality or longevity.
- While research on mTOR activation in the lab is concerning, tissue-specific effects in real life must be considered, and eating more protein does not necessarily lead to muscle cancer or enlarged organs.
- For individuals who are not strength training, BMI can be a useful metric for determining leanness, while for strength-trained individuals, body fat percentage is a better indicator, with lower levels generally associated with better health markers.
- Very high body mass can put stress on the heart and may lead to ventricular hypertrophy, but the body can adapt to these loads over time.
- Muscle growth effectively lowers blood sugar levels and increases insulin sensitivity, reducing the risk of type 2 diabetes, while both fat loss and muscle growth are highly effective in reducing fasting blood sugar levels and improving insulin sensitivity.
- High blood sugar levels and low insulin sensitivity are strongly associated with chronic inflammation, which is linked to various health issues, while muscle mass has positive effects on insulin sensitivity and reduces systemic inflammation, contributing to overall health and well-being.
- The benefits of muscle mass are generally positive up to the natural maximum achievable without taking androgens.
New Wave of Glucose Monitor Technology (57m57s)
- Continuous glucose monitors (CGMs) are becoming popular for tracking blood sugar levels and insulin sensitivity.
- CGMs can be useful for understanding how body composition affects health.
- Body composition significantly impacts health.
- Losing fat improves various health markers, regardless of diet quality.
- The combination of being lean and muscular has substantial health benefits.
- Most health biomarkers improve as leanness increases, with few exceptions.
- Extreme leanness (e.g., 5% body fat) is not sustainable and may have negative effects.
- Menno Henselmans shares his experience of being very lean (4-5% body fat).
- He describes feeling terrible at such a low body fat percentage.
- His body naturally tends to maintain a body fat percentage between 12% and 15%.
What People Are Getting Wrong (1h1m25s)
- Carbohydrate intake is overemphasized for strength training.
- Most supplements are overrated and provide minimal benefits.
- Exercise order is not as important as people think, and combo sets can be effective.
- Combining exercises for non-overlapping muscle groups can save time and be just as effective.
- Antagonist supersets, such as L-curls and leg extensions, can increase performance and save time.
Is it Worth Obsessing Over Small Details? (1h5m58s)
- People who are overly obsessed with small details of training and diet may not necessarily achieve better fitness results.
- Motivation is a significant factor in achieving results, and highly motivated individuals tend to get better results.
- It is important to find a balance between being overly analytical and being highly motivated.
- Obsessive individuals may be more consistent with their training and pay more attention to details, but they may also lack motivation.
- The worst combination is someone who pays attention to many details but lacks obsession, as they may be overly concerned with minor details while neglecting essential aspects of their training.
Keeping Motivation to Train High (1h8m19s)
- Intrinsic motivation, characterized by relatedness, competence, and autonomy, is crucial for maintaining high motivation for training.
- Crossfit fosters relatedness and a sense of community, promoting intrinsic motivation.
- Self-motivational techniques like self-talk and visualization can enhance motivation and performance.
- Religion can provide positive outcomes such as increased life satisfaction and happiness, despite its potentially irrational nature.
- Protein is vital for building and maintaining muscle mass, with an optimal intake of 0.8-1 gram per pound of body weight daily.
- Whey protein is the most effective protein for muscle growth due to its rapid absorption and high concentration of essential amino acids.
- Creatine, BCAAs, and HMB are supplements that can aid in muscle strength, power, recovery, and growth.
Most Underrated Bodybuilding Food (1h13m32s)
- Olives are a healthy and satiating food with great fat source.
- Berries are exceptionally satiating for their low calorie content.
- Pangasius fish is flavorful, has a good amount of protein, and contains omega-3 fatty acids.
- Eggs are not unhealthy but not particularly health-promoting either.
- They have a neutral effect on overall mortality and cholesterol levels.
- Some people may experience an increase in LDL cholesterol levels.
- Eggs are nutritious and have a good protein content.
- Red meat has mostly neutral effects on health.
- It is nutritious and has a lot of protein.
- Consuming red meat in moderation is not unhealthy, especially when it's not processed.
- Organ meats, such as liver and kidney, are very nutritious.
- They score high on nutrient indices.
- However, consuming a lot of organ meats may not lead to objective improvements in longevity or health biomarkers, unless there are specific deficiencies.
The Tribal Nature of Diet Culture (1h18m5s)
- Diet and nutrition have become a battleground for semi-religious existential wars between different tribes.
- The digitalization of society and increased welfare levels have reduced the importance of materialism.
- Social media has made things that signal identity more important than material goods.
- Diets have become identity indicators, with people caring more about whether they are carnivores or vegans than whether the diet is healthy.
- This is because diets are now seen as upstream from longevity, and attacking someone's diet is seen as reminding them of their impending death.

- Protein should be consumed throughout the day, with a focus on consuming it after resistance training.
- Whey protein is the most effective type of protein for building muscle.
- Casein protein is a slow-digesting protein that can be consumed before bed to prevent muscle breakdown.
- Plant-based proteins can be effective for building muscle, but they need to be consumed in larger amounts than animal-based proteins.
- Protein supplements can be a convenient way to increase protein intake, but they are not necessary for building muscle.
- Progressive overload is the most important factor for building muscle.
- This means gradually increasing the weight you lift over time.
- Focus on compound exercises that work multiple muscle groups at once.
- Train each muscle group 2-3 times per week.
- Get enough sleep and eat a healthy diet to support muscle growth. | <urn:uuid:127b5fc2-75ae-41df-a85f-5cef5de2533a> | CC-MAIN-2024-51 | https://www.getrecall.ai/summary/muscle-growth/the-new-science-of-using-protein-to-build-muscle-menno-henselmans | 2024-12-10T14:18:39Z | s3://commoncrawl/crawl-data/CC-MAIN-2024-51/segments/1733066061339.24/warc/CC-MAIN-20241210132922-20241210162922-00000.warc.gz | en | 0.937336 | 3,026 | 2.921875 | 3 |
