Corktown Historic District
Corktown Historic District
Bagley Street in Corktown
|Architectural style:||Colonial Revival, Late Victorian, Federal|
|Added to NRHP:||July 31, 1978|
Corktown is the oldest neighborhood in Detroit, Michigan, although the city of Detroit is twice as old. The current boundaries of the current district include I-75 to the north, the Lodge Freeway to the east, Bagley and Porter streets to the south, and Rosa Parks Boulevard (12th Street) to the west. The neighborhood was listed on the National Register of Historic Places in 1978.
The Corktown Historic District is largely residential, although some commercial properties along Michigan Avenue are included in the district.
The roots of Corktown lie in the Great Irish Potato Famine of the 1840s. The Irish immigrated to the United States in droves, and by the middle of the 19th century, they were the largest ethnic group settling in Detroit. Many of these newcomers settled on the west side of the city; they were primarily from County Cork, and thus the neighborhood came to be known as Corktown. By the early 1850s, half of the population of the 8th Ward (which contained Corktown) were of Irish descent. Historically, the neighborhood was roughly bounded by Third Street to the east, Grand River Avenue to the north, 12th Street to the west, and Jefferson Avenue/Detroit River to the south.
By the Civil War, German immigrants had begun making inroads into the Corktown neighborhood. By the turn of the century, the original Irish population had diffused through the city, and other immigrants, notably Mexican and Maltese, moved in. As the century progressed, southern migrants in the U.S. lured by the jobs in the automobile industry followed suit.
The residential section is listed on the National Register of Historic Places and is designated as a City of Detroit Historic District. The neighborhood contains many newer homes and retains some original Irish businesses.
The original buildings in Corktown are Federal-style detached homes and rowhouses built by Irish settlers. A worker's row house circa 1840 is located on Sixth Street and is one of the oldest existing structures in the city of Detroit. In further years, modestly sized Victorian townhouses with Italianate, Gothic, and Queen Anne elements were constructed.

Fuel economy: Windows down or air con on, which is better?

The UK summer has been as unpredictable as ever so far, but with temperatures soaring right now, what's really the best to keep cool in the car as you take advantage of the lockdown restrictions easing? Should you open your windows or turn on the air con?
It's a question that many drivers have pondered over the years, with many of you may already be aware there's apparently a magic number to take into account when it comes to deciding which is a more efficient way to keep cool; 45mph.
The Smart Climate menu in the new Volkswagen Golf
Below this speed it makes sense to open your windows to let a breeze. Above this speed, the drag effect of the windows being open, begins to make it more fuel efficient to shut them in favour of switching on the air con.
This advice is based on the results of a 2004 study by the Society of Automotive Engineers (SAE), which studied the impact of windows open vs. A/C in large saloons and sports utility vehicles.
Guideline advice
There are plenty of variables that this study couldn't have accounted for such as: how much the windows are open by, the aerodynamics of different car models, how long someone might use their air con for (as some use might only use it for a short blast) and the option of using the fan without turning on the air con. It's also not the most recent research.
As such, the 45mph figure is a guide, but a fairly good one. While all this might seem like a minor issue, getting it wrong can have a notable impact on your fuel economy; using AC can increase your fuel consumption by as much as 10% but opening the windows at higher speeds can increase fuel consumption by as much as 20%.
Mythbusters also took a stab at answering the question, finding in favour of windows down being more fuel efficient.
Meanwhile, another study has revealed that hybrid car fuel economy is harder hit by air con use than conventional combustion-only cars.
In a study by Emissions Analytics, it was found that the impact of AC on hybrid fuel economy was almost twice as much, with fuel efficiency dropping 6.1% in a hybrid car on average, compared to just 3.8% for standard petrol car and 4.6% for a diesel. This might be something worth bearing in mind, if you drive a hybrid.
What about air pollution?
The windows v air con debate isn't just about working out which is more fuel efficient. It is also worth considering your exposure to air pollution. While the 45mph line is a good guide, things get a bit more complicated when you are in bumper-to-bumper traffic.
In these situations, it is probably best to avoid using air con or opening your windows. However we know that in hot conditions that might be uncomfortable, so as a solution you could turn on the air con but close your air vents, so the air con merely recycles the cabin air rather than drawing the air from outside, where there is nose-to-tail line of traffic all belching out exhaust fumes.
What's else can I do?
There are old-fashioned ways too that you could consider to keep your car cooler too, such as trying to park in the shade or in a garage, opting for tinted windows or heat deflectors or just using a fan to keep cool.
What's best for fuel consumption?
There might be purist among you who think that the very notion of air con in cars in this country is a crime against fuel efficiency but we know that for many Brits, air con is now just a standard feature they expect to find – and be able to use – all we'd say is use it wisely and sparingly and you can stay cool without burning a hole in your wallet.
We could go into the environmental impact of various AC systems and the refrigerant gases they use, but that is probably for another article.
In most driving conditions though, apart from on the motorway, it's likely that a crack in the window, will work better for you than turning on the AC, but the choice is of course, yours.

Since time immemorial, women have been subjecting themselves to crazy beauty practices to look beautiful and be more appealing. Today, we have different products easily available on the market. But in ancient times, people had to get creative. From changing the shape of one's feet to using highly poisonous materials on the face, we bring to you 10 such craziest ancient beauty practices.
1. In China, foot binding was considered a mark of beauty until the 20th-century. Tight binding was applied to the feet of girls at a young age to modify the shape of their feet to look like a lotus. This resulted in limited mobility for women, and some even had to suffer from lifelong disabilities.
Despite the immense pain, women in China kept alive the tradition of foot binding for many years. The concept was made famous by a 10th-century court dancer named Yao Niang. Her feet were bound into the shape of a new moon! The emperor was enchanted by her dancing on just her toe inside a six-foot golden lotus. Eventually, other ladies of the court started trying out the method, and it turned into a tradition. It became a symbol of one's status along with beauty and sexuality. Down the line, it became so embedded into the Chinese culture that a girl without feet binding had only negligible chances of getting married!
The process starts when the girls are between four to nine years in age. This is the time when the arch of the feet is not fully developed and is easier to bound. The preparation involves the foot being washed with warm, herbed water and animal blood. This was done to soften the feet. Next, the toenails are clipped as far as possible to avoid growth. The toes on each foot were curled under the foot by pressing with great force. This was done until the toes broke. Once the desired lotus shape of the feet was achieved, bandages were used to tightly hold the feet in shape. Eventually, with time, the feet became numb.
There were many health issues related to this process the most common being infections. Blood circulation to the toes was completely cut off because of the tight binding. This meant that any infection on the toes would never heal and ultimately lead to rotten flesh. Moreover, the mobility of the women with bound feet was restricted to a large extent. Some even had to suffer lifelong disability in lieu of the broken bones and terrible infections. (source)
2. The Greeks and Romans used crocodile excrement in their body-toning mud baths. It was also used in face masks, as it was believed to slow down aging.
The ancient Greeks and Romans used various animals and animal byproducts for medicinal and beautifying purposes. One common belief was that reptile excrement had the power to slow down the aging process. So, the Greeks and the Romans used to fill their bathtubs with a mixture of warm mud and crocodile feces. They would then sit there for hours hoping their skin to magically turn younger. Some of the wealthy people were also known to create face masks out of the excrement and mud mixture. The great Greek physician, Galen, noted that women who desired luxury preferred crocodile dung face masks to complete body baths. This was definitely one of the grossest beauty practices, but still, nobody was harmed while trying it out. (source)
3. In 1936, Isabella Gilbert invented the "Dimple Maker" so that dimples could be "made to order!" The device consisted of a spring with two tiny knobs that press into cheeks to create the dimples.
Who doesn't love dimples? There are so many people who wish they had dimples. If only there was a machine that could magically create dimples on our cheeks! In reality, there existed one such machine. Known as the "Dimple Maker," it was created by Isabella Gilbert in 1936. The machine came with just simple instructions: "Wear dimplers five minutes at a time, two or three times a day, while dressing, resting, reading, or writing. Look into the mirror and laugh. There will be a semblance of a line where you should always place the dimplers until your dimples are made."
The device consisted of a spring-like contraption with two rounded knobs. The knobs were to be placed where the dimples are desired. So, the knobs would just press the cheeks hard to create two depressions on both sides of the face. The doctors at the American Medical Association denounced the machine in 1947, as they believed that the prolonged use of the machine might lead to cancer. (source)
4. Tho-Radia, a French cosmetics brand, manufactured products that contained radioactive chemicals like thorium chloride and radium bromide. They were supposed to provide a "radiant" skin.
With the discovery of radium by Marie and Pierre Curie in 1898, the entire scientific community jumped on it. It was not long before radium came to be used in medical and commercial requirements. Beauty is one segment that accepted radium with open arms.
Many cosmetics companies started infusing radium into their products with the promise of a more "radiant" skin. In 1933, Alexis Moussali, a pharmacist, and Alfred Curie, a Parisian doctor, joined hands to launch a range of French radioactive beauty products. The product range was called "Tho-Radia" and included a cleansing milk, skin cream, powder, rouge, lipstick, and toothpaste. The products were marketed as a scientific method of beauty. Advertisements showed a highly-glowing face that can be achieved by using the products. Furthermore, each advertisement carried claims such as "Stimulates cellular vitality, activates circulation, firms skin, eliminates fats, stops enlarged pores forming, stops and cures boils, pimples, redness, pigmentation, protects from the elements, stops aging and gets rid of wrinkles, conserves the freshness and brightness of the complexion." (source)
5. Belladonna or deadly nightshade was used in eye-drops by women to dilate the pupils of the eyes to make them appear seductive.
Crave seductive eyes? Put a drop of deadly nightshade into your eyes! That's what ancient Italian women used to do!
The common name "belladonna" for the poisonous nightshade came from its use by women to look more appealing. Bella donna is Italian for "beautiful lady." Women used to prepare drops from the plant and apply it to their eyes. This would give a pupil dilating effect which was considered seductive at that time. The drops act as a muscarinic antagonist, which means that it works by blocking the receptors in the muscles of the eye which, in turn, constricts the pupil in size. It was quite dangerous, as prolonged use had the potential to lead to permanent blindness. (source)
6. Ancient dentists recommended Portuguese urine as perfect teeth whitening ingredient. Urine jars from Portugal were shipped because people thought that it was a more powerful cleansing agent than "home-grown" Roman urine.
The first people to invent toothpaste for oral hygiene were the Egyptians. The ancient toothpaste was nothing like the ones we use today. They were just a mixture of pumice, a very light and porous volcanic rock, and wine vinegar. Next in the oral hygiene race were the Romans. They did not have any fancy kinds of toothpaste but a totally organic solution to oral hygiene. It was urine.
Daily teeth care for the Romans involved using a local toothpaste where the main ingredient was human urine. Wealthy Romans were ready to pay enough money to get their hands on the famous teeth-whitening toothpaste. Also, the urine was imported from Portugal. It was believed that Portuguese urine had more efficiency when it came to whitening than Roman urine. Sounds bizarre, but it's true. Later, the Portugal urine also made its way to mouth washing liquids in the 18th century. With the collapse of the Roman Empire, their oral hygiene methods were lost.
If we look into the science behind it, the Romans were actually on to something. Urine contains ammonia which is a great cleansing agent. Our modern toothpaste and mouthwashes contain ammonia to provide the whitening effect. (source)
7. Beauty patches, also known as "stick-on beauty marks," were a cosmetic staple in the 1700s. The patches came in a variety of shapes and sizes, like stars, moons, hearts and even more intricate designs like a horse and carriage.
During the 18th century, beauty patches were all the rage. They were used to cover up pimples or blemishes on the skin. This was one of the earliest examples of the use of beauty techniques to convert facial flaws into fashion statements!
Smallpox occurrences in the 18th century were majorly responsible for the emergence of these beauty patches. Very few people survived the pox, but for those who survived, they were left with scars. Enter beauty patches to hide those scars. The first beauty patches were made from costly fabrics such as silk or velvet. They were then coated with an adhesive so that they could be stuck onto one's skin. They came in a variety of decorative shapes like crescents, circles, hearts, triangles, stars, etc.
Eventually, the beauty patches turned into a cosmetic staple. People started adorning them even though they had no blemishes or pimples to cover. According to the Pitt Rivers Museum, "Women pasted them on the face, neck, and breast, according to a newly emerging language of symbolism: a patch above the lip meant coquetry, on a forehead, grandeur, and at the corner of an eye, passion." (source)

I am making a "halo" shader in unity using GLSL. And I've come to a roadblock.
What I need to do is take a texture, like the following, and make it transparent according to the darkness of it. And I don't want a cutout, because that cuts it off at a hard edge.
Default particle
This line of code doesn't seem to work.
gl_FragColor = texture2D( vec4( _MainTex.r, _MainTex.g, _MainTex.b, _MainTex.a), vec2(textureCoordinates));

1 Answer 1
Normally you store the transparency of a texture in the alpha channel, you can use an external editor like Paint.Net (free) or Photoshop to edit the alpha channels of a picture.
However since you're using shaders there is another trick you can do. A color is totally black if all it's color channels (R/G/B) are 0. It's gray when it's 128/128/128 and white when it's 255/255/255. If you want to determine the blackness you can take the average of the RGB channels, however a picture with bright red but no green or blue will still mean 'pretty black' and will still be 2/3rds transparent. However just try it for fun change your blend shader code to and see how it looks:
float blackness = (_Maintex.r + _Maintex.g + _Maintex.b) / 3.0;
gl_FragColor = texture2D( vec4( _MainTex.r, _MainTex.g, _MainTex.b, blackness), vec2(textureCoordinates));

I'd call that luminance or gray level or something, not 'blackness' (it's actually more like 'whiteness', since it's 0 for black and 1 for white). – Nathan Reed Jun 10 '12 at 5:20

HE (high-efficiency) laundry detergents are specialized formulas made to use in HE washing machines. The main difference between a HE detergent and a regular one is the amount of suds. HE detergents produce less suds and are designed for the lower water environments of HE machines.
How can you tell if you have an HE washer? Does HE detergent actually work? Can you use non-HE detergent in HE machines? Read on to find out.
Do You Have a HE Washer that Needs High-Efficiency Detergent?
What does HE mean on laundry detergent?
If you're shopping for an HE detergent for your high-efficiency washer, look for the blue and white oval with the letters "h" and "e" surrounded by a white swirl on the label. It should be the same symbol you saw on your washer.
The HE symbol might be located on the front of the bottle, or on the reverse, near the washing instructions and ingredients. When you see HE on a laundry detergent bottle, you'll know that this detergent is designed for HE washing machines.
HE Detergent vs Regular Detergent: Which Should I Use?
There are various types of laundry detergent for the various types of washers, kind of like there are different types of fuel for different types of engines. Just as you wouldn't put gasoline in a diesel car or truck, you should only use HE detergent in a HE washer.
You're probably wondering, "can you use HE detergent in a regular, non-HE washing machine?" The answer to that is, yes! While you should not use regular detergent in a HE washer for the reasons stated above, it is fine to use HE detergent in a conventional washing machine. You should increase the amount you use since more water in the washer cycle will dilute the detergent further. And remember, don't expect as many suds! HE laundry detergents are low-sudsing by design.
HE detergent vs Ultra-Concentrated Laundry Detergent
While almost all detergents today are HE, only some have the added feature of being ultra-concentrated. Detergents with the HE symbol on the bottle are formulated for the low-sudsing, low-water environment of an HE machine. Ultra-concentrated laundry detergents can be used in regular, non-HE washing machines and in HE washers if they are also HE detergents.
Swash® Liquid Laundry Detergent is both HE and ultra-concentrated - it's an 8x detergent. What sets ultra-concentrated detergents apart is that they use less water in their formulation. Large bottles of laundry detergent are diluted with water, while concentrated laundry detergents contain less water and are less diluted. As a result, you don't need to use as much detergent in every load to get the same cleaning performance.
Since ultra-concentrated detergents will be combined with water inside your washing machine, they don't need to dilute the detergent inside the bottle. By reducing the water and concentrating the detergent, you can have a smaller bottle that is easier to ship, pour, and store, taking up less room in your laundry area.

It has been found that at most sites this can be well represented by the two parameter Weibull probability density function. For example, if one were to average 10 resolution cells in a 4-look image, the speckle noise will be reduced to about 0.5 dB. \exp\left( We now present a simple derivation of a generalization of Lord Rayleighâs result, which will be Steven J.

Use of Weibull distribution to describe wind speed probability density. Rayleigh distillation systematics have been widely and successfully applied to understanding the microbiological sulfate-reduction process (see section 5.1) since the cell may be regarded as a partially closed system. The wave field is assumed to be Gaussian, which gives a reasonably good approximation of reality in most cases. The interaction between light and matter is extremely complex, and there is no easy way to fully describe it. This is also explicitly shown here.) Note that this trend of increasing Î'34S-S(-II) is not related to any change in the reduction process or the sulfur sourceâit is purely a result of sulfate reduction in a closed or partially closed system. Geographers can deduce from that a strong correlation, occasionally even a causality, between the two sets in terms of position and, in any case, an attraction between the two groups of places. S.

Rayleigh distribution is a continuous probability distribution for positive-valued random variables. It displays these results in a visual and digital way. If the answer is âTrueâ, the graph g is isomorphic to the theoretical graph considered. The identification of Rayleigh distribution processes in sedimentary rocks is important since this may be used to demonstrate whether the system is open or partially closed, a marine or basinal environment for example. In order to narrow the width of these distributions (i.e., reduce the brightness fluctuations), successive signals or neighboring pixels can be averaged incoherently (i.e., their power values are added). A close examination of an SAR image shows that the brightness variation is not smooth, but has a granular texture which is called speckle.

The Rayleigh distribution is related to the Gaussian distribution through the property that we have two independent normally distributed random variables Xâ¼N0,Ï2 and Yâ¼N0,Ï2, then the random variable R=X2+Y2 is a Rayleigh-distributed random variable with parameter Ï. For most practical offshore engineering purposes, this assumption works very well and gives good agreement with full-scale measurements. The phase angle is assigned randomly to each sinusoid. Before looking for minimum distances, it replaces values of zero (the distance of each city from itself) with the maximum distance and divides this distance, calculated in meters, to convert it into kilometers. The wave crests follow the Rayleigh distribution if the wave elevation is assumed to be Gaussian and narrow-banded.

|Abstract:||Background and aim of the study: Phonocardiography is a promising non-invasive diagnostic tool for the assessment of aortic stenosis (AS), and time-frequency representation is a potential tool to extract information from the phonocardiogram (PCG) signal. The study aim was to develop an acoustical method to predict the severity of AS. Methods: Normalized continuous wavelet transform (NCWT) and fast Fourier Transform (FFT) were used to perform a spectral analysis of the PCG signal. A multi-peak detection algorithm was developed to determine the dominant frequency (DF) of systolic murmurs (SM). The spectral ratio of the SM, integration of the NCWT of SM (SI), and combined information of SM and second heart sound, were also calculated. Results: The DF correlated best with the hemodynamic data: r = -0.72 with aortic valve (AV) area; r = 0.63 with maximal blood velocity through the AV; and r = 0.57 with mean pressure gradient across the AV. Based on DF and SI data, the study subjects (n = 59) were classified into three categories: severe AS; moderate AS; and other cases. The acoustical and echo classifications were in agreement in 50 subjects (85%). Conclusion: The acoustical method developed cannot predict accurately the severity of AS, but is valuable when conducting a screening classification before an invasive method is used. © Copyright by ICR Publishers 2005.|

Reorganisations of share capital: open offers and vendor placings
A characteristic feature of a rights issue is the provisional letter of allotment which entitles existing shareholders to subscribe for further shares in the company under the terms of the issue. However, a company can raise funds in other ways which are similar to a rights issue to the extent that existing shareholders are offered the opportunity to subscribe for the new shares. However, they are not conventional rights issues because there is no provisional letter of allotment which the shareholder can sell 'nil paid', ie before they have subscribed for new shares.
Arrangements alternative to a rights issue fall into two categories which are often known as open offers (or entitlement issues) and vendor placings. However, there is no commonly accepted vocabulary and vendor placings are sometimes described as open offers or entitlement issues and vice-versa. Therefore in any individual case it will be necessary to look at the underlying transactions not simply at the label used to describe them. In practice this should not be a problem as the arrangements are largely confined to public companies and you can follow the treatment described in Interactive Data publications (formerly Extel) unless the taxpayer objects.

Title: "Learning to be ill? Adaptive decision-making systems with limited information may cause ill health"
Non-communicable illnesses such as obesity, depression, and anxiety disorder are the dominant medical problems in the developed world, but their causes are poorly understood. Evolutionary explanations are limited to reasons why the deleterious condition could be adaptive and often fail to capture critical phenomena. For instance, explanations for depression focus on depressive behaviour as a way to avoid costly effort where benefits are small and/or unlikely, but fail to explain why low mood persists when the situation improves. Animals, including humans, do not always make optimal decisions but have evolved decision-making systems (or 'rules') that are adaptive generally. I will describe an emerging paradigm for understanding illness based on computational models of adaptive learning in which individuals face repeated choices among options that affect fitness and alter beliefs. Among populations of individuals all following adaptive rules a significant minority show behaviour associated with illness. For example, our model of depression predicts 5% of individuals will be inactive when it would be better to interact with the world, mimicking an effect of depression on behaviour. These explanations for depression, anxiety disorder and obesity contract strongly with the idea that the system is somehow malfunctioning; brains of depressive patients may be working perfectly but have inaccurate beliefs about current conditions. Our work suggests that medical interventions for these illnesses are unlikely to work because they do not adjust beliefs: effective treatments are likely to involve altering the experiences of adaptive decision makers.

How Chilean employers justify paying women less
Readers talk back
Must reads site wide
Gender pay gap is a problem for most women globally but at least Australian women are able to openly discuss and debate it.
Chilean women don't mention the gap for fear of losing their job. Arguments for paying women less in Chile centre on the role of women in that country. They are seen as homemakers while men are seen as workers.
Statistics from a national survey show that in 2009 women earned 15.8 per cent less than men. The difference is 37 per cent among male and female graduates.
Chile's Direccion del Trabajo (labour office) found that eliminating the gender gap would have a significant impact on poverty so perhaps it's time they started talking about it.
This story was first reported on IPS news

Background: Epidemiological studies have reported an association between asthma and migraine, mainly in adults. Objective: To examine the association between specialist-diagnosed asthma and migraine among adolescents. Methods: The electronic database of a recruitment center was retrospectively searched for all 17-year-old draftees during the years _PHONE_. Diagnoses of asthma and migraine were made by certified specialists. The prevalence of migraine was compared among draftees with and without asthma. Covariate data on socio-demographics and associated medical conditions were recorded. Results: A total of 113 671 adolescents were available for analysis. Asthma was diagnosed among 4.0% and migraine among 1.9%. Migraine was significantly more prevalent among adolescents with asthma [174 of the 4581 subjects (3.8%)] compared to those without asthma [1946 of the 109 090 (1.8%)] [OR = 2.17 (95% CI 1.86-2.55; P < 0.001)]. Rates of migraine among subjects with and without allergic rhinitis were 6.3% and 1.7%, respectively [OR = 4.04 (95% CI 3.58-4.56; P < 0.001)]. On multivariate analysis, there was a significant association between migraine and both asthma [OR = 1.42 (95% CI 1.19-1.68)] and allergic rhinitis [OR = 3.18 (95% CI 2.80-3.63)]. Other factors significantly associated with migraine were female gender, urban area of residence, recent immigration to Israel, having three or fewer siblings, and abnormal body mass index. Conclusion: Clinicians should be aware that asthma and allergic rhinitis are potential risk factors for migraine in adolescents. A combined finding of these conditions and recurrent headache is highly suggestive of migraine and warrants a different diagnosis and treatment approach from sinusitis.

Ice-wetch, polygon pond cut at a eroding river cliff, Lena Delta, Sakha Republic, Siberia, Russia
The polygon ponds in the flat sediment tundra of the delta are formed by ice-rings, which form against each other ring-formed walls. - The Lena delta is one of the largest still pristine river deltas in the world. Its many naturally meandering arms form a magnificent tree-like shape.
On August 12, 1996, the Russian Republic of Sakha (Yakutia) significantly expanded the Lena Delta state nature reserve. At 14,330 square kilometres, the Lena Delta reserve ("Zapovednik") was already one of the largest and most important nature reserves in the Arctic. With its new size of 61,320 square kilometres, the expanded Lena Delta Reserve is now the largest protected area in Russia and one of the largest on earth. It is, however, only a small part of Sakha's "Gift to the Earth". Sakha, a republic approximately the size of Western Europe, decided in 1994 to designate at least 20% of its territory as a nature reserve.


Tara. The most popular river in Montenegro
Tara's character is turbulent: it flows between high rocks and impregnable mountain slopes, and only being closer to the confluence with Piva becomes calm and slow. The bottom of the river is pebbly, without silt, vegetation and algae, and the color of the water changes from emerald greenish to foamy white.
Facts about Tara
The Tara River flows through the northern part of Montenegro for 144 km. At its joining with the Piva River, it forms the Drina River, which flows into the Sava River. Tara feeds on the waters of small mountain rivers such as Lucica, Drysia, Draga and Vashkivska, and the waters of the beautiful waterfall Baylovic Sige, which falls from the Bucevica cave.
The water temperature in Tara almost never rises above 12 degrees even in the hottest months, but in winter it does not freeze. The water in the river is so clean that it is allowed to drink without cleaning.
Europe's largest canyon
Tara is famous for the fact that it forms the largest canyon in Europe, which is 82 km long and reaches a depth of 1300 meters. This canyon is listed as a UNESCO World Heritage Site and is part of the Durmitor National Park. It lies between the mountains of Zlatni Bor and Lubishnya on the one hand, and Durmitor and Sinyavina on the other.
The canyon of the river Tara in Montenegro amazes travelers with its beauty and grandiosity. Along the canyon you can see pebble and rocky terraces surrounded by dense coniferous forests, high cliffs, small coves and sandy beaches. There are about 80 large caves on the slopes of the mountains near the river.
Flora and fauna
The canyon is full of endemic plants and animals, relict black pines, whose age reaches 400 years, grow in its primeval forest "Crna Poda". Also there are black ash, oriental hornbeam, linden, elm, beech, cork oak, maple, fir and spruce,which grow here. Brown bears, wolves, deer, wild boars and wild goats can be found among the animals, and the bird world contains 130 species. The waters of Tara are full of fish.
The legendary Djurdjevic Bridge
The canyon crosses the Djurdjevic Bridge, which was built in _PHONE_. It was the tallest road bridge in Europe before the beginning of the 2000s. The length of the five-arch bridge is 365 meters and its height is 172 meters!
Also along the Tara River you can see a lot of destroyed Turkish checkpoints and several orthodox monasteries.
What to do?
Extremals go to Montenegro especially for rafting on the waters of Tara. You can see here rafts, kayaks, inflatable boats during the period from May to September. The most popular route has a length of 60 kilometers; it is designed for one day and involves crossing 21 thresholds. The route can be really difficult and dangerous for beginners.
Many tourists come to Tara Canyon and Djurdjevic Bridge in summer – these places are one of the most famous sights in the country.

Forest of Neldoreth
The Forest of Neldoreth was the beech-forest that lay between the banks of the Esgalduin River and the Mindeb River that formed the northern and lesser part of the Kingdom of Doriath. It was in the Forest of Neldoreth that Lúthien was born and later these woods were part of the enclosure called the "Girdle of Melian".
It was under the trees of Neldoreth that Beren first beheld Lúthien dancing in the moonlight. Later, when Sauron had cast Beren into a pit and Lúthien resolved to rescue him, Thingol had her imprisoned in a house built high in the branches of the highest tree of the forest, called Hírilorn.
When Treebeard was carrying Merry and Pippin to Wellinghall he chanted to them about walking in the woods of the First Age. He recalled coming to Neldoreth in Autumn and enjoying the gold and red and sighing leaves of Taur-na-neldor (an alternate name for the forest).

 - Missing Translations
Missing Translations
If a translation on a specific locale is missing, by default Transifex Native will return the string in the source language. However, you can change that behaviour by providing a different missing policy.
You can start using Transifex Native by creating a Transifex Native project.
Source String
This is the default policy, where the source string will appear when a translation is missing.
TRANSIFEX_MISSING_POLICY = 'transifex.native.rendering.SourceStringPolicy'
# _t("Hello, friend") -> returns "Hello, friend"
Pseudo Translation
This is a nice way to do translation QA during development, as pseudo-translated strings stand out and are easy to identify.
TRANSIFEX_MISSING_POLICY = 'transifex.native.rendering.PseudoTranslationPolicy'
# _t("Hello, friend") -> returns "Ȟêĺĺø, ƒȓıêñđ"
It's advised that you do that only for your development environment, as you probably don't want to show pseudo translations to your actual users on production.
Source String Inside Brackets
Another way to show that a string is α placeholder text is to show it wrapped around some symbols.
 {'start': '[', 'end': ']'},
# _t("Hello, friend") -> returns "[Hello, friend]"
Source String with Extra Characters
Translations in some locales are typically longer than in English. This policy allows you to do QA for your UI during development and make sure that longer strings can be accommodated by your current UI elements.
 {'extra_percentage': 0.5, 'extra_str': '~#'},
# _t("Hello, friend") -> returns "Hello, friend~#~#~#"
A Complex Policy
You can also combine multiple policies to get a result that stands out even more visually and also supports features like extra length or something custom you might want.
Simply set the policy to a list, with each item being a tuple of a string, depending on whether or not it needs parameters:
 {'extra_percentage': 0.5},
 {'start': '{', 'end': '}'},
# _t("Hello, friend") -> returns "{Ȟêĺĺø, ƒȓıêñđ~extra~}"
Custom Policy
You can easily create your own policy:
# _t("Hello, friend") -> returns a custom string


The main objective of this post is to give a brief introduction to Homing Missiles in Game (2D). A script for Homing missile is also included and explained in the article.
What is a Homing Missile?
What is the logic behind Homing Missiles?
How to use Homing Missiles in Unity?
Have these Questions in Your Mind?
No worries. You will get a satisfactory answer to all those questions, right here.
Let's, start with Introduction
You might have seen Homing Missiles in many movies.
Real life example of homing missile
Remembered these scenes from "Marvel's The Avengers" movie?
If you are not a Marvel fan don't worry, I am here to help you.
"Homing Missile is the missile which locks target and chases the target until or unless it reaches the target and blasts itself."
There are plenty of games which are using Homing Missiles.
Excited to implement Homing Missiles in your game?
I know you are.
Let's set the scene setup first
Scene Setup:
 1. Create two 2D Objects name them "Missile " and "Target".
 2. Add a Sprite to them. (You can download the project from below link).
 3. Add rigidBody 2D in missile and add Script also name it as "Homing Missile"
How it actually works?
You might think,
It is easy to Implement Homing Missile. Just use MoveToward/Lerp until it reaches the target. Then just write code and look at what is going on in your scene. (try it and then read further to understand)
Working of Homing Missile
It is reaching the target properly but there is no feel of a rocket. (Right Brain:-What is wrong with my code?)
Checkout an actual script for Homing Missiles.
public class HomingMissile : MonoBehaviour
 public Transform target;
 public Rigidbody2D rigidBody;
 public float angleChangingSpeed;
 public float movementSpeed;
 void FixedUpdate ()
 Vector2 direction = (Vector2)target.position - rb.position;
 direction.Normalize ();
 float rotateAmount = Vector3.Cross (direction, transform.up).z;
 rigidBody.angularVelocity = -angleChangingSpeed * rotateAmount;
 rigidBody.velocity = transform.up * movementSpeed;
I think script is short but not a sweet one. You can use this homing missile script for your code.
Don't be scared, I'll show you how to do it.
Let's start with the table to introduce variables:
Variable Name Variable Type Description
rigidBody RigidBody2D rigidBody of the missile to add velocity and change angle.
target Transform To get the position of the Target.
angleChangingSpeed float The speed to change the angle
movementSpeed float Speed of movement
Pure Mathematics: (Open your Brain's left part)
actual path of homing missile
You need to understand this Picture. That's How our Homing Missile Works.
First, what you need is "Direction".
direction= targetPosition (target.position) - missilePosition(rb.position);
vector substraction
This is how subtraction of two Vector happens (Pythagoras Theorem).
Normalization means converting vector to unit vector.
Vector A(3,4)
Normalized(A)=(3/3*3+4*4, 4/3*3+4*4)=(3/5,4/5)
Find Amount of rotation to do that.
Vector Cross Product
Blue Arrow(direction)
Red Arrow(Missile Transform)
green(Resulting Vector).
All three Vectors are perpendicular to each other.that's why we needed z-axis only.
Now we need to change angularVelocity of our rigidBody.
rb.angularVelocity = - angleChangingSpeed * rotationAmount.
Minus Sign(-) is used to reverse the direction of movement.
Adding Velocity to our rigidBody.(just changing the Angle is not Enough).
rb.velocity=tranform.up * movementSpeed.
Stop cheering just yet!
This is not the end!
Missile needs balancing between angleChangingSpeed and movementSpeed.
What if there is no balance between angleChangingSpeed and movementSpeed (Great question! Open right brain is needed here! )
Missile heading to the target
In the above Image, the missile is heading forward to the target, there is no problem here.
velocity force vs angular velocity
In the above Image, the target has moved to a new position. The missile continues to go toward the target due to angular velocity (in red), while still going to the place where the target used to be (in black) due to its velocity. (Thinking what is wrong.?)
velocity force vs angular velocity -2
In the above Image, the missile's velocity forces it to move at the side of the target (black) while the angular velocity tries to pull the missile to the target. (Now you might feel there is something suspicious).
orbit dead loop
In the above Image, the missile falls into a stable orbit around the target and never reaches its goal.
The black arrows indicate a velocity vector while the red lines indicates angular velocity. (That's why need a balance between angleChangingSpeed and velocity).
That is how whole Universe is trapped (Thank God for this error else there is no life!).
Now, How to Fix this Problem?
Well, There is no particular formula to balance them, but by Increasing angle or decreasing velocity will help you there.
 - Don't go with very small speed so your missile loses the feel of Homing Missile and Don't make it Extreme fast it will be trapped in the orbit.
 - Don't make angleChangingSpeed too small else it will fall in to trap and to high angleChangingSpeed loses the feel of your game.
That's It for Homing Missile from my side..!
But I'm Hoping to see your homing Missiles in my comment box as well as in your game.. ;)

Cats in the Cradle – What Does That Phrase Mean?
By: Rebecca O'Connor
Read By: Pet Lovers
Email To A Friend Print
The phrase "Cats in the Cradle" is a familiar one to most everyone, but it is a phrase that brings about mixed emotions. Is the cat being in the cradle a good thing or a bad thing? Does the image bring about feelings of family and childhood or danger and death? Let's investigate some of the myths and truths surrounding cats living with babies and you can decide for yourself what this means to you.
Harry Chapin's Song
American singer/songwriter Harry Chapin's famous song has made the phrase famous. "Cat's in the cradle and the silver spoon, little boy blue and the man on the moon..." The song was actually written by Chapin's wife Sandy, a poet and a writer. She wrote the words for the song for their son Joshua before he was born. She showed them to her husband but Chapin wasn't too interested in it at the time. However, once his son was born, Chapin realized the power of the words and what they meant to him personally. He recorded the song and it became the best known of all of his work.
"Cat's in the Cradle" tells the story of a father who is too busy to spend time with his growing son. Despite the fact that the father is constantly putting off quality time with his son, the son sees his father as a role model and a fine example of who he wants to grow up to be. In the end the son does grow up to be just like the father and as the aging patriarch reaches out to his son for quality time, his boy is simply to busy with his family. The refrain uses the phrase "cat's in the cradle" and these words bring up images of a young family and the short and sweet the time of infancy. However, a cat in the cradle wasn't always a warm and fuzzy image.
Take my Breath Away
Have you heard the old wives' tale of how cats can steal a baby's breath? Chances are it's a familiar story to you if you have had children. It is a story that even today crops up in forums and from well-meaning, but uneducated advice givers. Expectant mothers are often told that they need to get rid of their cats before the baby comes. But are cats really dangerous to babies?
According to the strength of this story may be traced to a 1791 jury that rendered a verdict in England that a Plymouth child had been killed from a cat sucking away its breath. In actuality there was likely no obvious cause for the infant's death and so the jury passed the blame onto the cat, because of course back then, everyone knew that cats might suck a child's breath away.
A 1929 article in the Nebraska State Journal also quoted a doctor who supposedly witnessed a cat actually sucking an infant's breath. He describes "the family pet in the very act of sucking a child's breath, lying on the baby's breast a paw on either side of the babe's mouth, the cat's lips pressing those of the child and the infant's face pale as that of a corpse, its lips with the blueness of death."
Today we are familiar, although still mystified, by Sudden Infant Death Syndrome (SIDS). It leaves you to wonder if these children didn't die of SIDS and the nearby cat was the best explanation for the death. Cats are curious creatures and the crib is a warm cozy place. It would be easy for them to be implicated in the murder.
However, all of these evil or jealous cat stories are a lot of hooey. It is unlikely that a cat would even suffocate a child accidentally. In fact, I myself grew up sleeping with the cat in my crib. Accidental scratching is a more likely concern and mothers should always keep an eye on their young children when they interact with the cat, whether it's in the cradle or elsewhere. Of course, it's easy enough to keep the cat out of the nursery if there are any concerns. For me, "cats in the cradle" makes me fondly remember a childhood surrounded by animals. How about you?

text: © 2020, Emerald Publishing Limited.Purpose: This study aims to investigate the evolution of factors that influence the current and future use of video streaming applications by Millennial consumers. Design/methodology/approach: Combining technology acceptance, perceived values and user identity theory this study used factor analysis and multiple regression to examine data from a survey of 292 university undergraduates. Findings: Millennial's current and future use of video streaming services remains driven more by social and emotional values and their effect on identity salience with their choice of content. Ease of use, convenience and monetary value remains less of an influence currently but may become more important in the future with the continued maturity of the industry. Practical implications: The results of this study suggest that video streaming service providers should be developing business models that recognize the increasing importance of emotional appeal and self-identity of their service offerings as the industry matures and competition increases. Originality/value: The research is novel in addressing future video streaming service provision by examining changes in young consumer behaviour over time within a similar sample population and considering the growth and technological advancement of video streaming services. The results are significant in addressing the gap that exists in understanding whether perceived values for technology adoption of the same product or service by millennials change over time and the implications that have for product and service providers.

We present here our studies concerning the variation of refractive index with the optical gap in amorphous silicon prepared by glow discharge decomposition of silane. The study has been carried out in the light of the models of Penn, Wemple-Didomenico, Ravindra et al., Moss and Bahl-Bhagat. It is essentially seen that the model of Bahl-Bhagat is good enough to explain the relative shifts in the refractive indices in terms of the changes in the gaps on introduction of hydrogen into amorphous silicon. However, because of weaknesses associated with the fitting parameters, we propose here an alternate model which explains fairly well the dependence of the index of refraction on the optical gap. Furthermore, to explain the gradient of the refractive index vs optical gap plots, we see that a simple model like that of Moss would suffice. This is all the more interesting by virtue of the fact that the Moss formula is basically representative of the atomic picture. Of course, the constant depends on conditions during formation of the sample. Under some limiting conditions, the Bahl-Bhagat relation is shown to reduce to the linear form like that of Ravindra et al. We also attempt to analyse qualitatively the dependence of dispersion energy and the average excitation energy on temperature in the light of the Wemple-Didomenico model. The present study has been carried out for samples prepared by glow discharge at different substrate temperatures and with different hydrogen concentrations.

I have a WinForms application and a Panel Control. The panel control has a VScrollBar control for vertical scrolling. Everything works fine except right now I have my VScrollBar maximum value set to 100. The problem is, I need the Maximum property to be about 4 billion, however, since Maximum is only an Integer, I can't set it to the proper value. So, my question is, how do I get around this? I know there are text editors and file viewers that claim to view more then 4 gigs of data, so how would a scrollbar in an application like that work?

A scrollbar is a GUI control. Innately, the number of steps it can display is limited to the number of vertical pixels on your screen. Therefore, you could consider setting the maximum value to anything above that to be simply for developer convenience, to make the math easier.
How do applications deal with scrollbars? In theory, you'd want to parse the file first, to find out how many lines are in the file, and use that as your logical maximum. In reality, reading 4 GB of data when the file is opened would kill performance, so that wouldn't work.
If I were implementing this, I would set the scrollbar maximum is set to a large value, say 10,000. When the scrollbar is used, the scrollbar value is divided by 10,000 to get a percentage, and the editor shows that section of the file.
Don't think of things in terms of scrolling down so many lines. Instead, think of it as jumping to that percentage offset of the file, reading the data there, and displaying that.

Well, you could just set Maximum to int.MaxValue and scale the retrieved value to your real maximum value. This should be enough precision to avoid loading too much data.

You use a percentage. There is no need to set it to the same as the number of lines.

This is a good idea except when on my Scroll handler, I am getting ScrollEventArgs that has a property called NewValue which is an int. So if it returns to me 58, for example, meaning 58%, how do I know how far down to scroll? 58% is a large chunk of data when your talking about a total of 4 gigs. – icemanind Jun 29 '11 at 17:47
If you set maximum to int.MaxValue and minimum to int.MinValue you should be pretty close. – Alex Peck Jun 29 '11 at 18:00
Also consider that unless you have 1 byte of data per line, you will have a lot less than 4 billion lines, even for 4 gigs of data. – Mike Caron Jun 29 '11 at 18:07

A proactive transfer policy for critical patient flow management
Revista : Health Care Management Science
Tipo de publicación : ISI Ir a publicación
Hospital emergency departments are often overcrowded, resulting in long wait times and a public perception of poor attention. Delays in transferring patients needing further treatment increases emergency department congestion, has negative impacts on their health and may increase their mortality rates. A model built around a Markov decision process is proposed to improve the efficiency of patient flows between the emergency department and other hospital units. With each day divided into time periods, the formulation estimates bed demand for the next period as the basis for determining a proactive rather than reactive transfer decision policy. Due to the high dimensionality of the optimization problem involved, an approximate dynamic programming approach is used to derive an approximation of the optimal decision policy, which indicates that a certain number of beds should be kept free in the different units as a function of the next period demand estimate. Testing the model on two instances of different sizes demonstrates that the optimal number of patient transfers between units changes when the emergency patient arrival rate for transfer to other units changes at a single unit, but remains stable if the change is proportionally the same for all units. In a simulation using real data for a hospital in Chile, significant improvements are achieved by the model in key emergency department performance indicators such as patient wait times (reduction higher than 50%), patient capacity (21% increase) and queue abandonment (from 7% down to less than 1%).


Audigier: L'éducation civique dans l'école française (Citizenship Education in French School)
François Audigier
Abstract: Since ten or fifteen years ago, civic education is coming back to the foreground of the news. It is now an obligatory school subject in primary and lower secondary school, the college, namely nine years of a schooling which it is as a rule the same for all pupils. The author introduces programmes from primary school and from the college. However, between official programmes and what is effectively taught, differences are often very large. What some primary school's teachers say about what they teach and about college's pupils provides another point of view on civic education. A short evocation of the history of civic education in French school puts in prospect actual choices and specific problems of this school subject, in particularly its difficult stabilisation. The article closes with the presentation of some tensions and contradictions which are necessary to take into account to think and to implement civic education.

Québec has various national symbols and emblems. They reflect Québec's history, its wintery climate and its collective identity.
The Québec flag was officially adopted in 1948. The cross on the flag evokes the faith of the province's founders, and the fleur-de-lis and blue background recall its French origins.
The coat of arms, in its present form, was adopted in 1939 to symbolize the historical realities of Québec. The shield bears three gold fleur-de-lis on a blue background symbolizing the French regime, a gold lion on a red background symbolizing the British regime, and a branch with three maple leaves reflecting the period before the founding of the Canadian federation.
This motto, created by the architect of Québec's parliament building, Eugène-Étienne Taché, symbolizes the importance of remembering Québec's history.
Québec chose the yellow birch as its emblematic tree to emphasize the importance Quebecers place on their forests.
As the floral emblem of Québec, the iris highlights the importance of water and wetlands in the balance of nature.
The snowy owl symbolizes the whiteness of Québec's winters, its roots in a semi-Nordic climate and its vast territory.

Hypotonic vs Isotonic vs Hypertonic: Which Performance Solution is Right for You?
Aqualyte Solution 25g
There are lots of different performance drinks on the market and they use different solutions for varying results. Here at Aussie Natural, we understand that you sometimes need a little more than just water to get your hydration levels up and we carry Aqualyte for quick hydration. Today, we're looking at the various sports drink solutions on the market so you know which one is right for you!
Most people have heard about isotonic drinks. They're designed both to deliver hydration and energy to the body and are often used during endurance sports. Isotonic drinks are around the same concentration as human blood. Isotonic drinks generally have around 6-8% carbohydrates and tend to be most useful during short, high intensity exercise. While isotonic drinks are low in sodium, a lot of isotonic drinks are high in sugar and can also upset the stomach in large quantities which can have a dehydrating effect.
While other performance solutions are focussed on hydration, hypertonic solutions have a focus on providing energy. Although they do offer hydration, this is secondary to energy delivery. Hypertonic drinks have a higher concentration than your blood and have plenty of carbohydrates to help fuel intensive activities. Because hypertonic drinks are more focussed on giving the body carbohydrates through salt and sugar, they don't offer the thirst quenching benefits of other solutions if you're dehydrated. Hypertonic solutions are often used as a recovery drink and it's important to remember that if you're using this option while exercising, you also need a drink which combats dehydration. Because their purpose is to delivery energy, they're also comparatively high in salt and sugar so should be used in moderation.
If you need quick hydration, hypotonic solutions are the way to go. These drinks are a lower concentration than your blood and deliver fast hydration for the body due to their ability to be absorbed quickly into the bloodstream. They're low in both sugar because their purpose is to quench thirst rather than provide energy. Hypotonic drinks help replace fluid lost through sweat and are great at preventing dehydration during exercise or when working outside. This performance solution is also gentle on the stomach so you're less likely to experience bloating which can occur when fluid isn't absorbed properly.
At Aussie Natural, we carry a range of Aqualyte supplements to help ensure you stay hydrated. Aqualyte is an electrolyte and hypotonic solution which helps your body replace fluids lost through sweat to prevent dehydration. Aqualyte is low in sugar, gluten free and is available in a range of delicious flavours. We offer tubs or sachets for the ultimate in convenience.
To find out more about Aqualyte solutions, contact Aussie Natural today on 1300 360 332.

The Difference Between White Gold and Platinum
Platinum and white gold are two very different metals. The biggest differences between platinum and white gold are that platinum is a naturally white metal and is more dense and durable.
The difference in cost is primarily due to platinum's rarity and higher level of purity in platinum jewelry. When comparing costs, keep in mind the maintenance required over a lifetime for white gold, such as rhodium plating to keep it white, reshanking and retipping the prongs.
Platinum may be a higher investment initially, but its enduring nature makes it the best value in the long run. Below is a table to help better understand the differences between the two metals. Keep these facts in mind the next time you're at a jewelry store.
One of the most durable of precious metals. When scratched, metal is merely displaced and very little is lost. When scratched, slivers of metal are lost resulting in faster metal loss.
A real white metal Yellow gold mixed with whitening alloys, such as nickel. Will yellow without repeated rhodium plating.
Strength and durability creates the safest setting for diamonds. Metal moves with force rather than breaks. Gold is more brittle so increased chance of prongs breaking after repeated force.
Loses very little metal to everyday wear; little maintenance required. Loses metal at faster rate; may need to be reshanked or retipped with everyday wear.
Hypoallergenic, regardless of alloy Nickel alloy may cause allergic reactions
Platinum jewelry is 90-90% pure platinum Most gold jewelry is 59.5%(14K) or 75%(18K) gold
Platinum is 30 times more rare than gold About 2,700 tons of gold is produced and made into jewelry each year vs. 88 tons of platinum.
Platinum is 60% heavier than 14K gold and 40% heavier than 18K gold. You can feel a distinct difference between platinum and white gold.
Comments (4)
 1. 14-karat gold is really 58.33% gold & remainder is alloys. 24-karat = 100%. Whatever the gold karatage may be, divide it by 24 and that's your percentage of actual gold in the piece of jewelry.
 2. Jill says:
 I just want to say that I had a set of 14 Karat while gold wedding rings. There was a diamond solitaire and a plain wedding band. I got them in 1963 and had them for thirty years. They never yellowed, I never had to have them rhodium plated, and the prongs were still fine after wearing for thirty years. White gold may not be as hard as platinum, but it is harder than yellow gold.
 3. Hi Jill. 18kt white gold actually IS harder than both platinum and sometimes yellow gold. In fact, that's the point, it's harder and more brittle than platinum, which is softer and more durable–meaning the metal can get pushed around but not lost, rather than scratched away like gold…Keep in mind, the higher karat the gold, the softer it is.
 White gold is never white, it's sort of a gray-brownish color, without rhodium plating, that will eventually wear off.
 Note to editor, platinum jewelry is generally 90-95% pure.
 Keep enjoying beautiful jewelry guys–I know I will continue enjoying to make it!
 -all the bestEtienne Perret

Create a Retro Urban Gig Poster in Photoshop
Digital graphics are largely dependent on the software used to create them. Given the clean, pixel-perfect nature of Photoshop, artworks always risk looking too perfect therefore it's important to learn how to bring nature's random variations into our digital creations. In this tutorial we'll create an atmospheric poster for a dance party using the textured, retro look that's so popular nowadays.
Tutorial Assets
We will make use of a texture and a photograph. Here are the download links:
Step 1
Create a new document in the B2 format which is traditionally associated with posters. It measures 500x707 mm and of course you should choose the CMYK color mode and 300 pixels/inch since we're designing for print (1a). Fill the canvas with a medium blue-green solid tint (1b).
Step 2
Hit B to activate the Brush Tool and select a very large, round and soft-edged brush preset. Pick a light blue-green shade and start painting randomly across the canvas (2a). Keep going using different hues, both light and dark blue, and vary the brush's diameter to create a hazy pattern of swirls (2b). Go to Filter > Blur > Gaussian Blur and use a high enough value to smooth the pattern, eliminating any visible harsh brush strokes you might have (2c, 2d).
Step 3
Pick a light yellow color and create a small circle on a separate layer (3a). Double click the layer to open the Layer Style window and add a 1px Stroke in the same color (3b). At the same time reduce the layer's fill to 0 so only the stroke will be visible. Reduce the Opacity to 50% also (3c).
Step 4
Duplicate the circle three times and vary the opacity of the copies. The largest circle's Fill should not be 0 but 10% (4a, 4b). Group the 4 circles together and scatter a few copies across the top section of the canvas, scaling them and making them more or less transparent (4c).
Step 5
Duplicate the background layer by first double-clicking it (to turn it into an editable layer) then hitting Command+J (5a). Go to Filter > Noise > Add Noise and choose 2% (5b). Now click on the mask button at the bottom of the Layers palette to give the layer a blank mask (5c). Click the mask then hit B to activate the Brush. The foreground/background colors will be automatically changed to white and black. Hitting X will reverse them. Paint black strokes on the canvas with the big soft brush tip you used earlier to erase some parts of the noisy background (5d). The result is barely visible at this resolution but now the background transitions smoothly from polished to noisy (5e). It's a subtle effect that can be skipped but it adds some nice little variation.
Step 6
Let's create an interesting line pattern to add complexity to the background.
Draw a vertical line with the Line Tool (U). Keep using the light yellow from the circles (6a). Make evenly spaced copies across the entire width of the poster (6b) then duplicate and rotate them 90 degrees to create the horizontals. Add the necessary lines to cover the height (6c).
Step 7
You can collapse the horizontal and vertical lines by grouping them together then hitting Command+E. You should have two layers now. Select the vertical lines and go to Filter > Distort > Wave. Use the settings in image 7a to turn them into an interesting broken pattern (7b). Now go to Filter > Distort > Polar Coordinates and make sure the first option, Rectangular to Polar, is selected and press OK (7c). Now the lines have been arranged into a one-point front perspective radial pattern (7d).
Step 8
Select the horizontal lines and apply the Twirl filter from the Distort group (8a). The lines now follow an uneven wavy arrangement that pulls slightly to the top right corner (8b). Reduce the Opacity to 50% (8c) then duplicate the lines. Rotate the new layer 90 degrees to create the vertical waves (8d). The circles may disappear under the grid so bump up their opacity to make them more visible (8e).
Step 9
Place the cardboard texture in the document and resize it to fit the canvas (9a). Switch it to the Multiply blending mode (9b). The shade looks good but it's a bit too dark. Bring up the Levels (Command+L) and move the center slider to the left to increase the overall brightness without changing the black and the white points (9c). Now the image is lighter (9d). The background is finished.
Step 10
Place the skyline picture at the bottom of the canvas (10a) and set it to Multiply (10b). Add a Hue/Saturation adjustment layer (or the corresponding Adjustment if you're in Photoshop CS4). Activate Colorize and match the sliders to image 10c until the buildings have a retro brown tint. Beware that the Adjustment will affect all layers underneath it so click on the clipping icon to affect only the skyline (10c, 10d).
Step 11
On a new layer behind the "cityscape" create a tall red rectangle to extend the leftmost skyscraper (11a). Change it to the Lighten mode, 60% opacity (11b). By the way, here's a screenshot of our layers so far (11c).
Step 12
As you can see the rectangle doesn't match the skyscraper's perspective (12a). Correct that by hitting Command+T (Free Transform) and by selecting Skew from the right-click menu. Skew the rectangle to the right until it matches the inclination of the building (12b). Now hit Q to enter Quick Mask mode. Paint the top of the rectangle with a soft black brush (12c) then hit Q again. A selection marquee will appear: click the Mask button to add it as a mask (See Step 5). The rectangle now fades away at the top (12d).
Step 13
Add a Ripple filter from the Distort group (13a) to make the rectangle wavy (13b). Now add a Radial Blur (from Filter > Blur) (13c) to turn the rectangle into a smoke column (13d).
Step 14
With the same technique create three shorter smoke columns behind the right-hand skyscrapers, fading them at about half the poster's height (14a). Activate the Custom Shape Tool (U) and choose the crescent shape from the shape menu (14b). Draw a crescent around the first circles we created, using the previous light yellow and setting the layer to the Overlay mode (14c).
Step 15
The necessary typography should be added in Illustrator because it handles type better than Photoshop but for the sake of this tutorial we'll stick to one software. Add a line of text in orange in Overlay mode so the background shows through (15a). Add the rest of the text in light yellow, Overlay mode (15b). Finally add a Drop Shadow to the main text and the crescent moon (15c) to make them easier to read (15d). The poster is finished.
In this tutorial we have seen how easy it is to create interesting patterns with simple lines and Photoshop's powerful Distort filters. Sometimes it's important to get rid of the over polished digital edge to avoid the otherwise inevitable uniform look. One way to do that is by employing textures and photographs. With minimal editing they can add a nice retro taste to any clean composition that needs a bit of grunginess.

MODULE 1 - WIND
What is wind? How do you measure it? Students construct anemometers to measure wind speed, collect data, and compare wind velocity in different locations. This module contains the very basis of sailing knowledge - an awareness of wind and from which direction it is blowing.
MODULE 2 - BUOYANCY
What makes a boat float? What is the basis for a sound hull design? Students test their creative and cooperative skills in this group module which is as fun as it is educational. The fun and learning continues as they put this concept to practical use when sailing on a 420 or a J-22 in our protected marina.
MODULE 3 - SAIL AREA
What shape are sails and why? How do we calculate the area of a triangular sail? What is the perimeter of a sail? Students learn a practical application of the Pythagorean Theorem and a more in-depth understanding of a sail, which is actually a three-dimensional object that creates lift when wind flows around it.
MODULE 6 - MARINE DEBRIS
In this module, students spend time observing and collecting debris on a nearby beach. What appears to be a pristine seashore from a distance actually contains more man-made objects than one can imagine! Students participate in the Rozalia Project by cleaning up and recording marine debris for this national project.
MODULE 7 - UPWIND SAILING ANGLES
Students learn the advantages of tacking a boat at 90 degrees and how they can apply this principle to racing or sailing a boat upwind in optimum fashion.
MODULE 8 - LAND AND SEA BREEZES
Students learn the difference between a land and sea breeze and what causes each to occur. The San Francisco Bay is a perfect venue for this discussion.


YOU MAD? Regional variations in anger expressed in tweets
"You mad?" – The internet, it seems, represents a perfect place to vent anger, start a flamewar, and engage in uncivil behavior. Especially in unmoderated comment forums, the combination of distance and anonymity can be a driving force for vitriolic behavior (see Why on is Everyone on the Internet So Angry?)
In this exploration into my big data set of geo-tagged tweets, I examine anger and hatred. Unlike internet comment threads, twitter users are not anonymous. Yet anger on twitter remains a concern for many. Researchers have compared the anger response in twitter as psychologically similar to road rage – it acts at more of a distance, it happens more quickly, and it is more explosive. Furthermore, of all the emotions expressed on social media, it seems that anger is the quickest emotion to spread. In a short time, anger and rage can spread within several degrees of separation.
In this analysis, I have more modest aims:
 - Track anger expressed by usage of the words "anger" and "hate" and their multiple forms (e.g., anger, angry, angriest, etc.)
 - Track anger expressed by emotions (?????? )
 - Examine how word and emoticon expressions of anger corroborate each other
 - Examine regional variations expressions of anger
Analysis of 24 million geo-tagged tweets show that on average, 0.78% tweets are using forms of the word "hate" or "anger." That's not a lot. Of course, there are other ways to express anger in a tweet, and this is just a rough tool. On average, 0.30% of tweets use the anger emoticons. The image shows the hot-spot analysis of regional differences in the distribution of tweets (words and emoticons). Fully red sections use anger statistically significantly more in tweets, fully blue sections use anger less in tweets. The map shows a few things:
 - There is significant regional variation in the use of anger signifiers, and these regional difference represent stable and relatively large regions (not county by county)
How big are those regional differences? In some cases, the differences are small. Some of the orange and red areas are only slightly above the nationwide average (0.90% vs. 0.78%). Sometimes the difference is stark. For example, portions of Michigan and Texas (at 1.5%) are six times more likely to express anger than portions of Hawaii (at 0.25%), and four times more likely as a state like New Jersey (at 0.5%).
Why do these difference exist? I do not know. Perhaps there are some regional differences in expectations for civility, or different norms for if (or how) the same emotion is conveyed online. Perhaps people in different parts of the country are simply less angry than other parts. I did try lining up this map with some socio-economic indicators like crime-rate, unemployment rate, income distribution, and others. I didn't get very far.

The Effect of Exploration Intensity on Analysts' Forecasts
This study examines the relations between the intensity of reported exploration activity by mining and exploration companies and analysts' private information search activities and their forecast accuracy. Under Australian accounting standards, firms can either record exploration expenditure as an expense as it is incurred, or as an exploration asset (i.e., exploration expenditure is capitalised). The accounting choice for exploration expenditure could have potential impact on analysts' forecasts. It also examines the relations under the different accounting treatment for exploration expenditure.
This study examines whether greater intensity of exploration activity motivates analysts to acquire and process relatively more private information to meet investor demand and whether this affects the accuracy of analysts' consensus forecast. It also examines whether the capitalisation of exploration expenditure can reduce uncertainty analysts have about the future economic outcomes of exploration investments, and improve the accuracy of their forecasts.
The study finds that the proportion of private information contained in analysts' forecasts increases with the intensity of exploration activity. We also find that the accuracy of analysts' consensus forecast improves with the intensity of exploration activity. The results are robust for firms choosing to capitalise their exploration expenditure.
Using the extractive industry as a specific setting, this study evaluates the role of analysts in moderating high information asymmetry exhibited in this industry. The findings are useful to investors and academics because it addresses how accounting matters when investing.
