Authentic Assessment - " Mission Possible or Mission Impossible?
Faculty of Computing, Health and Science
School of Natural Sciences / Centre for Ecosystem Management
This paper describes the successful implementation of authentic assessment items within two undergraduate units in the School of Natural Sciences. It argues that the content of any authentic assessment needs to ne contextualized and thus discipline specific. Within the field of environmental planning, there is an ongoing debate about both the nature and definition of the subject which makes creation truly authentic assessment problematic. The environment planning unit now includes three assessment items which replicate many of he practices required of an environmental planner. In contrast, in the field of chemistry, it is difficult to replicate the work practices of a professional chemist within the University learning environment. In the chemistry unit, an industry trip and seminar have been included to provide a more authentic learning environment for the students. The paper shows that it is possible to create assessments that are authentic and also meet the University's learning requirements.

Chemical structure of an orange colored azo dye
Azo dyes are organic compounds bearing the functional group R−N=N−R′, in which R and R′ are usually aryl. They are a commercially important family of azo compounds, i.e. compounds containing the linkage C-N=N-C.[1] Azo dyes are widely used to treat textiles, leather articles, and some foods. Chemically related to azo dyes are azo pigments, which are insoluble in water and other solvents.[2][3]
Many kinds of azo dyes are known, and several classification systems exist. Some classes include disperse dyes, metal-complex dyes, reactive dyes, and substantive dyes. Also called direct dyes, substantive dyes are employed for cellulose-based textiles, which includes cotton. The dyes bind to the textile by non-electrostatic forces. In another classification, azo dyes can be classified according to the number of azo groups.
Trypan blue is an example of a direct dye, used for cotton.
Physical properties, structure, and bonding[edit]
As a consequence of п-delocalization, aryl azo compounds have vivid colors, especially reds, oranges, and yellows. An example is Disperse Orange 1. Some azo compounds, e.g., methyl orange, are used as acid-base indicators. Most DVD-R/+R and some CD-R discs use blue azo dye as the recording layer.
Many phenolic diazo dyes participate in tautomeric equilibria shown here in simplified form (Ar = aryl).[4]
Azo dyes are solids. Most are salts, the colored component being the anion usually, although some cationic azo dyes are known. The anionic character of most dyes arises from the presence of 1-3 sulfonic acid groups, which are fully ionized at the pH of the dyed article:
RSO3H → RSO3 + H+
Most proteins are cationic, thus dyeing of leather and wool corresponds to an ion exchange reaction. The anionic dye adheres to these articles through electrostatic forces. Cationic azo dyes typically contain quaternary ammonium centers.
Most azo dyes are prepared by azo coupling, which entails an electrophilic substitution reaction of an aryl diazonium cation with another compound, the coupling partner. Classically coupling partners are other aromatic compounds with electron-donating groups:[5]
+ Ar′H → ArN=NAr′ + H+
In practice, acetoacetic amide are widely used as coupling partners:
+ Ar′NHC(O)CH2C(O)Me → ArN=NCH(C(O)Me)(C(O)NHAr′) + H+
Azo dyes are also prepared by the condensation of nitroaromatics with anilines followed by reduction of the resulting azoxy intermediate:
ArNO2 + Ar′NH2 → ArN(O)=NAr′ + H2O
ArN(O)=NAr′ + C6H12O6 → ArN=NAr′ + C6H10O6 + H2O
For textile dying, a typical nitro coupling partner would be disodium 4,4′-dinitrostilbene-2,2′-disulfonate. Typical aniline partners are shown below. Since anilines are prepared from nitro compounds, some azo dyes are produced by partial reduction of aromatic nitro compounds.[3]
Many azo dyes are produced by reactions from pre-existing azo compounds. Typical reactions include metal complexation and acylation.
Azo pigments[edit]
Azo pigments are similar in chemical structure to azo dyes, but they lack solubilizing groups. Because they are insoluble in virtually all media, they are not readily purified, and thus require highly purified precursors.
Synthesis of C.I. Pigment Yellow 12, an azo pigment (also classified as a diarylide pigment).
Azo pigments are important in a variety of plastics, rubbers, and paints (including artist's paints). They have excellent coloring properties, mainly in the yellow to red range, as well as good lightfastness. The lightfastness depends not only on the properties of the organic azo compound, but also on the way they have been absorbed on the pigment carrier.
In order for dyes to be useful, they must possess a high degree of chemical and photolytic stability. As a result of this stability, photolysis is not considered to be a degradation pathway for azo dyes. In order to prolong the lifetime of products dyed with azo dyes, it is essential to ensure stability against microbial attack, and tests have shown that azo dyes biodegrade negligibly in short term tests under aerobic conditions. Under anaerobic conditions, however, discoloration may be observed as a consequence of biodegradation.[6]
Safety and regulation[edit]
Many azo pigments are non-toxic, although some, such as dinitroaniline orange, ortho-nitroaniline orange, or pigment orange 1, 2, and 5 are mutagenic and carcinogenic.[7][8]
Azo dyes derived from benzidine are carcinogens; exposure to them has classically been associated with bladder cancer.[9] Accordingly, the production of benzidine azo dyes was discontinued in the 1980s in many western countries.[10]
European regulation[edit]
Certain azo dyes degrade under reductive conditions to release any of a group of defined aromatic amines. Consumer goods which contain listed aromatic amines originating from azo dyes were prohibited from manufacture and sale in European Union countries in September 2003. As only a small number of dyes contained an equally small number of amines, relatively few products were affected.[2]

Operations on Submodules
Let $M$ be a module. Let $X$ be a subset of $M$. Then define $\langle X \rangle$ to be the submodule of $M$ generated by $X$, that is, the intersection of all submodules of $M$ containing $X$. (Note that the intersection of modules is itself a module.)
Let $\{ M_i | i \in I\}$ be a family of submodules of $M$ (for some indexing set $I$). Define their sum as for ideals: $\sum M_i$ consists of all finite sums $\sum x_i$ where $x_i \in M_i$ and almost all $x_i$ are zero. Note $\sum M_i = \langle union M_i \rangle$.
Thus the submodules of $M$ form a complete lattice with respect to inclusion (the glb is interesction and lub is the sum).
Isomorphism Theorems
1. If $L \supset M \supset N$ are $R$-modules then
\[ (L/N)/(L/M) \cong L/M \]
2. If $M_1, M_2$ are submodules of an $R$-module $M$ then
\[ (M_1 + M_2)/M_1 \cong M_2 / M_1 \cap M_2 \]
 1. The map $\theta:L/N \rightarrow L/M$ given by $x+N \mapsto x+M$ is a surjective $R$-module homomoprhism with kernel $M/N$, thus the result follows by the fundamental homomoprhism theorem.
 2. Apply the same reasoning to the map $\theta:M_2 \rightarrow (M_1 + M_2)/M_1$ given by $x \rightarrow x + M_1$.
Let $I$ be an ideal of $R$. Then define the product $I M$ to be the set of all finite sums $\sum a_i x_i$ where $a_i \in I, x_i \in M$. It is a submodule of $M$.
Let $N, P$ be submodules of $M$. Define
\[ (N:P) = \{a \in R | a P \subset N\} \]
(similar to ideal quotients). It is an ideal of $R$. Define the annihilator of $M$ by
\[ \mathrm{Ann}(M) = (0 : M) \]
If $I$ is an ideal of $R$ contained in $\mathrm{Ann}(M)$ then $M$ can be viewed as an $R/I$-module by defining $(x+I) m = x m$ for all $x \in R, m \in M$. This map is well-defined since $I M = 0$.
An $R$-module is faithful if $\mathrm{Ann}(M) = 0$. Note $M$ is faithful as an $R/\mathrm{Ann}(M)$-module.
The following can be easily verified:
 1. $ \mathrm{Ann}(M+N) = \mathrm{Ann}(M) \cap \mathrm{Ann}(N) $
 2. $ (N:P) = \mathrm{Ann}((N+P)/N) $
Let $x \in M$. Then define $R x$ to be $\langle x \rangle$, that is the set of all $a x$ where $a \in R$. A set $X \subset M$ is a set of generators of $M$ if $M = \langle X \rangle$ (so every element of $M$ can be written as a linear combination of elements of $X$). If $M$ has a finite set of generators then $M$ is said to be finitely-generated.

Why Did Jesus Tell His Disciples to Buy Swords?
Why did Jesus command his disciples to buy swords in Luke 22:38?
Now, however," He told them, "the one with a purse should take it, and likewise a bag; and the one without a sword should sell his cloak and buy one. For I tell you that this Scripture must be fulfilled in Me: 'And He was numbered with the transgressors.' For what is written about Me is reaching its fulfillment."
So they said, "Look, Lord, here are two swords."
"That is enough," He answered. (Lk 22:36-38)
A lot of people assume that it was in order to defend themselves, and use this as an argument for warfare and liberal gun laws. But if it's one thing we can be sure of, it is that Jesus definitely didn't intend the swords to be used for self-defense.

The Demonic Factor in Mass Shootings: Exorcism as Gun Control
by William De Arteaga.
The gun control debate
Gun control is regularly debated in the United States, not the least when horrible mass shootings occur in schools, cinemas, and other places. What is lacking in the dispute is a consideration of the spiritual dimensions of gun control. The silence from the pulpit on this issue is especially notable. Perhaps it is because the clergy dislike weighing in on issues that are not specifically defined in scripture and because American Christians often have very different and passionate opinions on this issue.
In this blog let me offer some thoughts on one dimension of the debate that has received little clergy attention: the demonization (obsession or possession) of many of the mass shooters.
Right at the start let me say that talking about the demonic realm for the Christian is both necessary (if one is true to the Gospel) but difficult due to its multifaceted complications. As Christians, we are in a state of constant spiritual warfare against the demonic realm. But as in most wars, there is a "fog of battle" in which our intelligence of and knowledge of the enemy is limited. Some Christian writers claim more than we can know about the demonic, as in the exact order of hierarchy and functions of the "thrones, principalities, powers, etc." Especially difficult is the demarcation between psychological issues, chemical imbalances, etc., and demonic activity in and through a person.

Ed and Edd, But Not Eddy
Ed and Edd decided to build competing roller coasters. Ed built his roller coaster 40 feet high that will travel down on a straight slope. Edd built his roller coaster 40 feet high, but his travels down a curved slope (steep at the beginning, levels out at the end with no bumps).
If both cars are released at the same time (they cars are identical), which one will arrive at the bottom first?
 1. curved slope will win
 2. The curved slope will win because you will pick up more speed at the beginning.
 3. mike - are you sure about this? I spent a lot of time considering this (this happens to be right up my alley, as you may know by now), and I think I may disagree. you do in fact get more speed at the beginning, but you have a greater distance to travel, since you have to travel the length of the line, and if the line is curved, it will be longer (i.e. the shortest distance between two points is a straight line).
 Consider the following extreme example. Let's say that your "curved line" consists of a vertical drop for the full height, then a flat line going to the end, while the "straight line" coaster is just a linear slope between the start and end. We'll say that it's 45 degrees for simplicity (that is, length=height=h). If you crunch the numbers, it comes out that it takes slightly longer to get to the end of the "curved" coaster, unless I made a mistake.
 "Straight Line"
 distance to travel = d = h*sqrt(2)
 acceleration = a = g cos(theta) = g/sqrt(2)
 d = h*sqrt(2) = (1/2)*a*t^2
 t = 2*sqrt(h/g)
 "Curved Line"
 First Leg:
 distance = d = h
 acceleration = a = g
 d = h = 1/2*a*t1^2
 t1 = sqrt(2*h/g)
 final velocity = v = sqrt(2*g*h)
 Second Leg:
 distance = d = h
 acceleration = a = 0
 d = v*t2
 t2 = d/v = h/sqrt(2*g*h) = sqrt(h/(2*g))
 t = t1+t2 = (sqrt(2)+sqrt(1/2))*sqrt(h/g)
 since (sqrt(2)+sqrt(1/2))>2, the "curved" scenario takes longer, by my figuring. Anyway, it seems like this would hold true for all similar scenarios if it held true for this case, but I'm not sure about it.
 I bet this was a lot more than you bargained for on this question...sorry.
 4. As usual for me, I'm not sure. It's going to take me some time to figure this one out.
 At first glance, I would think it would matter how far you are dropping. Off the top of my head (I haven't worked my way through your math, yet) I can definitely see there would be a tipping point where the straight line would catch up to the curved line, but for a short drop, the curved line (I would think) would win.
 And, if there is a tipping point, I wonder what that would be.
 And, that all supposes that I'm right about the quick pick-up of speed.
 Let me work through your math and see what I can see.
 5. Alright, after trying my hand at some algebra, I think I came up with time on a curved track is (sqrt(2) + sqrt(2))*sqrt(h/g) which is bigger than time on a straight track 2*sqrt(h/g).
 If either of us is doing the math correctly, the straight line wins.
 Sorry about that.
 6. it's ok. I'm going to actually look at some Hamiltonian / Lagrangian techniques and see if I can solve this definitively with calculus of variations. you've piqued my curiosity. I'll get back to you.
 7. Mike,
 I crunched the numbers on one that slopes just a little more sharply than a straight line, then levels off at the bottom, and it is indeed faster. If you slope just a little more at the first, it is faster, but the extreme case I gave is slower, which means there is some maximization curve which will do it in the fastest time. Anyway, good question, even if you didn't realize it at the time ;-)
 9. Wow, that was totally not obvious to me. Very interesting though.
 I really wish I could say I knew it all along, but I'm guessing everyone here would know better by now!

Quick Answer: Are Red Nose Pitbulls more aggressive than blue nose?
Red nose pit bulls may appear more intimidating than blue nose pit bulls, mostly because of their muscular build. … However, if trained and loved, red nose pit bulls can be extremely friendly, soft, and loyal companions. They possess a stocky frame, which is quite apparent in all pit bulls.
Are Red Nose Pitbulls more aggressive?
Red Nose Pitbull is More Aggressive Than Other Breeds
Though it has a small body compared to other breeds, people still find it intimidating because they did not find them friendly enough until recent times. The title of being aggressive comes from their ancestors, who were used in the blood-spattering fights.
What is the difference between red nose and Bluenose pitbulls?
Blue Noses have more of a grayish or charcoal color nose, and the coat is often a similar gray color. Red Noses have a reddish/pinkish nose, often with red or auburn fur. With both types, inbreeding is a concern with breeders whose focus is physical characteristics over the health of the dog.
IT IS INTERESTING: Is dads a good dog food?
Are blue nose pitbulls more aggressive?
Blue nose pit bulls are actually extremely loving, loyal, and even good with children. This particular breed of dog was NOT bred to be aggressive or to fight, which is a common misconception with many dog breeds, especially the blue nose pit-bull.
Why are Red Nose Pitbulls illegal?
A banned breed? Pitbull are now outlawed in the UK as part of the 1991 dangerous dogs act. This was done in part due to the dangerous reputation of these dogs, but also because of their use in dog fighting rings. 'Bully' breeds often stem back to the days of bear baiting and other similar 'sports'.
Why do pits turn on their owners?
Fear aggression is a major reason why dogs attack their owners. If your dog has a bad history or she has been beaten and mistreated before, then they feel threatened and become defensive.
Are Red Nose Pitbulls good family dogs?
A Red Nose Pitbull craves interaction and the companionship with their favorite humans. They're good pets for the family and are renowned for being superb with children! This breed is ideal for families that have experienced taking care of larger breeds.
What is the rarest pitbull color?
By far the rarest of Pit Bulls are those that are Merle. The Merle Pit Bull is distinct in its genetics and many times exhibit unique color schemes and a trademark blue eye. The blue eye or eyes are also referred to as crystal and glass eyes.
How can you tell if a pitbull is purebred?
How to Tell if It's a Pitbull Breed
 - Look at the size and ratios of the dog. Pitt bulls are two and one-half feet tall at the shoulder or shorter. …
 - Look at the dog's coat. The color is irrelevant. …
 - Examine the dog's head and neck. A pit bull's head is extremely wide from ear to ear, across the brow and from cheek to cheek.
IT IS INTERESTING: Why is my puppy restless at night all of a sudden?
Do blue nose pitbulls bark a lot?
These dogs naturally love people. Like, love-love people so much that you'll have to do training to keep them from jumping up on people. They rarely bark so they don't make great watch dogs either.
What are blue pits worth?
The Blue Pit is no different from other pit bulls, and it's becoming popular among breeders, but it's still rare to find. A Blue Nose Pitbull puppy can cost around $1,000 to $3,000.
Can blue nose pitbulls swim?
Pit bulls are capable of swimming and liking water, but their build and facial structure make it harder for them than other breeds. If you have a water-loving pitbull, you don't have to keep them dry, instead find them safer alternatives for aquatic play, such as a kiddie pool, shallow stream, or gently sloping beach.
How do I make my red nose pitbull muscular?
You can start with simple exercises such as walking, running, and making him run through poles. These exercises will surely make your Pitbull gain more muscles. Exercise alone, on the other hand, will not make your Pitbull gain more muscles. You also have to closely monitor his diet.
How do you tell if your pitbull is a red nose?
If it is red or reddish-brown in color, then you have a red-nose pit bull. If it is gray or light black, then you have a blue-nose pit bull. Other colors include black and pink. "Butterfly" noses are red with lighter pink patches.

The Stream Doctor
October 20th, 2003
Q. From W. Powell. Hi Doc: For twenty five years I've been fishing for trout during the winter and for more than half of that time I've had doubts about the survival rate of fish released when the water temperatures are so cold that the fish's metabolic functions are lower and the forage levels are severely decreased. Although I experience my most productive fishing from November through March, I would certainly rather discontinue the practice than kill fish. Have you any light to shed on this issue?
A. First of all, I'll relieve your concerns; enjoy your winter fishing. Here's why.
We're looking at several interacting factors here that influence the potential impact of winter trout fishing. Let me discuss these with you.
Evidence from some studies in southern Ontario revealed that during winter, trout remained thin despite having full stomachs. In other words, although food is plentiful (see below) and the trout feed regularly, their metabolic rate is too slow to assimilate the food and convert it to body tissue. Similar results have been found in California and elsewhere in Canada. This would indicate that trout, being in poorer condition during winter, might be more susceptible to fishing impacts.
On the other hand, I talked to two local fisheries biologists (one state and one university) about your question. The state biologist said that in the fisheries he supervises in this area, he sees no detrimental impact of winter fishing on local trout populations. The key word here is "populations." Biologists think in terms of overall fish populations when interpreting impacts, whereas individual anglers are probably concerned with impact on individual fish (is the one I just released going to make it or not?) as well as what impact they may be having on the overall population. His overall reaction based on his experience was to go ahead and enjoy your winter angling. The university biologist thought that factors favoring trout survival during winter were related to the fact that trout are more lethargic in colder water, fight less, and thus experience less stress than those fighting in warmer temperatures.
Another point in this respect is the problem of trying to answer your question in generalities without knowing where you fish or the type of water. Whereas the state biologist found no problems here, I expect that if I called enough biologists, I'd find one who did indeed find some negative impact of winter fishing on a particular population. In other words, different populations may respond differently. For instance, tailwater fisheries, which experience fairly uniform temperature conditions, will probably show no impact to seasonal differences in angling.
Colder water holds more dissolved oxygen; thus, oxygen saturation is the norm at this time of the year so this shouldn't add to any stress. Further, the very fact that the fish's metabolic functions slow down possibly indicates that they are less susceptible to stress at this time.
One point the state biologist did make, however, was this. He did some studies on individual fish survival from handling in winter conditions, particularly ice fishing. For ice fishing, the longer a fish was exposed to freezing air temperatures, particularly the gills, the less chance it had for survival. Thus, the less you expose the fish you catch to the air when it is freezing, the better their chance for survival.
Contrary to your belief that forage levels are low, this is usually the time of greatest abundance for immature aquatic insects. Remember, most insects emerge and deposit their eggs during the warmer months. The eggs hatch and the developing instars grow during winter, reaching their maximum size in spring and summer just prior to emergence. Thus, highest populations of immatures are present during the winter months, although they may be smaller in size initially. As populations develop, the nymphs and larvae get larger and fewer in numbers as natural mortality occurs.

The use of Drones in cinematography, allows filmmakers to carry us to unique vantage points to provide audiences with an overlaid perspective. High-end visual effects help convey the emotional message of their story by removing the audience from themselves and providing a voyeuristic view of the world.
These remotely piloted aircraft systems provide a cost-effective means of delivering technically difficult shots to achieve a director's vision through smooth and stable camera movement using virtually any camera or lens. When off the shelf solutions are not enough, our team will design and build a custom air mobility cinematic solution to carry the heavier payloads for multiple cameras and large lens packages.
Feature effects:
 - Tracking Shot is achieved by matching the speed and maintaining focus while following or tracking the subject.
 - Reveal Shot provides an intro, outro or wow effect by starting out of view and then moving into view
 - Pedestal Shot provides creative freedom as the drone flys up or down without moving the camera.
 - Aerial Pan Shot provides stunning visual effects through gimbal-mounted, moving or hovering camera drones.
 - Fly Over Shot provides a geographical perspective illustrating the scale of an object or landscape with the camera focused on one subject while the drone passes overhead.

As if deadly sinkholes and Burmese pythons weren't enough, now Florida may find itself contending with another summer of giant mosquitoes that pack a ferocious bite, LiveScience reports. Dubbed gallinippers, the quarter-sized mosquitoes hatch after a flood or rainstorm, and saw a bumper crop after Tropical Storm Debby struck Florida last summer. Now another rainy season could produce even more: "I wouldn't be surprised, given the numbers we saw last year," says an entomologist.
A gallinipper is 20 times the size of a typical mosquito, "and it's mean, and it goes after people, and it bites, and it hurts," says Anthony Pelaez of Tampa's Museum of Science and Industry. A gallinipper bite "feels like you're being stabbed." What's more, they may be resistant to bug repellent (the Orlando Sentinel recommends a DEET-containing repellent all the same) and like to strike fish, wild animals, and pets. Neat factoid: Entomologists don't always recognize the term "gallinipper," which arose in Southern folk culture. But the insect's first mention dates back to 1897, when a writer called it "the shyest, slyest, meanest and most venomous of them all." (Read more mosquito stories.)

Wow, the pre school children in Harlow have really enjoyed sharing there home made chatter boxes. Chatterboxes were originally developed for school-age children with communication difficulties. They are now widely used with pre-school children. They can provide hours of fun and develop children's knowledge, language and communication. The talk and exploration that goes on between children and adults, as they share the contents of the box, is vital for maintaining the children's engagement and learning.

Each of the previous editions of Legend of the Five Rings was connected to a specific time period. The first edition was set before the events of the CCG. The second edition bumped the timeline to the Time of the Void. The third edition came out current with the CCG story at the time. The fourth edition opted to be timeless to allow fans to use whatever time period they wanted. This left a lot of the game's history out of the core book. This makes the fourth edition versatile, but left out a lot of the player created history and backstory. Imperial Histories was created to fill that void.
Imperial Histories is a guide to various points in the history of Rokugan. Many of the periods have been seen in other sourcebooks or editions. Some have been referred to in historical accounts. And a few are brand new to the book. Each of these is set ups as a campaign possibility with new rules, new schools and, in some cases, modifications to the existing rules for different eras of the Empire. This book is aimed at GMs looking for campaign ideas or fans wanting historical information in one place.
Imperial Histories is available in hardcover and PDF. The book follows the same art and layout style as the Legend of the Five Rings core book. Most of the artwork is from the more recent sets of the CCG with the chapters broken up by two page spreads. Appropriate art is used where available. The book includes a sidebar talking about the time periods that don't use accurate art. There is an index in the back. Unlike the core book PDF, neither the table of contents nor the index are hyperlinked. There are one or two repeats of art from the core book but the majority of pieces are new to the RPG line.
The chapters each detail a different period in Rokugan history. It starts with the Dawn of the Empire, when the kami walked the earth. The book also details more famous elements of history such as the first two arcs of the CCG. The Day of Thunder is when many fans of Legend of the Five Rings came into the game. It was followed by the Spirit Wars and the Four Winds saga. Each of these gets a chapter. The book rounds out with two alternate timelines. The Heroes of Rokugan illustrates a living campaign that's been going on for years. One Thousand Years of Darkness takes place in a world where Fu Leng, the Lord of the Shadowlands was not defeated on the Day of Thunder and rules over the Emerald Empire.
Each chapter ends with mechanics relevant to the chapter. This usually means new schools, different schools or rules modifications. There are a few settings that involve gaijin, which add rules for things like firearms and non-Eastern weaponry. The rules for playing a gaijin essentially boil down to: don't. Full rules might appear in a later book but the authors make an argument that there are plenty of other fantasy games on the market that cover that ground well.
The most compelling chapter is One Thousand Years of Darkness. This dark setting is one the fans have been waiting for. The timeline puts the players as part of the rag-tag rebels still fighting against the dark Emperor Fu Leng. This game of samurai already thrives on tough choices between duty and honor. This setting makes those choices even tougher. Fans of horror will love being desperate demon slayers as well as dark intrigues to try and save an Empire that might not be worth saving anymore.
One of the chapters not in the book is the current CCG storyline. Other storyline updates have filled entire books. Fans looking to see how the current timeline is shaping up will be disappointed. AEG has plans for a second book like this next year. Rather than just updating characters and storylines, these books could be a gateway for fans of the RPG to keep up with the CCG and fans of the CCG to try out the RPG. These camps have been separated for far too long. Not telling the ongoing story here is a missed opportunity.
The Heroes of Rokugan chapter misses in a few areas. It reads like someone's campaign that already happened rather than a jumping off point for a new campaign. The story has some interesting elements and characters but doesn't feel ready to run out of the book like the others. The same information can be picked up for free on the campaign website. Having it here seems like a bit of padding, especially when there are a lot of other time periods that could have fit in the book.
GMs looking for material to mine will have a lot to choose from. Things from the alternate timelines could easily make themselves seen in home games. Historical schools could be reskinned or used to make an NPC unique. There's a ton of material here to put into any game regardless of the setting. Each chapter also has enough material for the basis of a campaign. GMs looking to run Legend of the Five Rings after a campaign or too will find the information here very useful.
Bottom Line: A great book for GMs looking for a time to set their new Legend of The Five Rings campaign.

The Great Chia Glossary
This guide will act as a glossary for many of the concepts utilized in Chia. If you are familiar with how Bitcoin transactions work, a lot of this will be familiar.
 - Coin (TXO/transaction output) - A coin stores value. All coins are generated as the output of a transaction or a coinbase reward or fee target. A coin is spent exactly once, allowing its value to go into other coins, and is then permanently destroyed. Each unspent coin is locked with a ChiaLisp program which is that coin's puzzle, and whoever has the information to solve that puzzle is the person who can spend that coin. The most basic puzzle has a public key and accepts a solution which contains a list of conditions signed by the corresponding private key, so only the owner of the private key can unlock the coin and spend it.
 - Unspent Coin (UTXO/unspent transaction output) - A coin which has been created but not yet spent and hence is storing value. Unspents (UTXO set/unspent transaction output set) - This is the set of all unspent coins on the network. It is used to check if a transaction is valid, acting as a lookup for the puzzles. It maps a coin ID to a birthdate in blockheight. A transaction must contain a reveal of the information used to calculate the ID in order for it to be possible to validate because the unspents doesn't contain that information, only hashes which can be used to validate it.
 - Coin ID/CoinName (TXO ID/transaction output ID) - The ID of a coin in Chia is generated by hashing the primary input ID, puzzle hash, and amount concatenated in that order. This is very different from Bitcoin which uses much more data to form the TXO ID, restricting what smart contracts are capable of. (See also: SegWit)
 - Primary Input/Parent - When a coin is created the coin that was used as input in the transaction is designated as the primary input. This is used to create the coin ID. If more that one coin is used up as an input in a transaction then one of the coins is designated the primary input, and the others simply reinforce the transaction.
 - Spend/CoinSolution - A spend is a reveal of a coin's ID, along with the full puzzle code, and a solution to be ran with the puzzle. The result of a spend is determined by the returned Op Constraints after running the puzzle with the solution.
 - Spend Bundle - A spend bundle is a collection of spends grouped together with an aggregated signature to be sent to the network.
 - ChiaLisp - ChiaLisp is the Turing-complete functional language which the puzzles for spending coin are programmed in. For more information see our CLVM Guide
 - Puzzle (Scriptpubkey) - A ChiaLisp program which specifies the behaviour of a coin when it is spent. A puzzle can either reject a solution or output a set of constraints.
 - Solution (Scriptsig) - This is some ChiaLisp which is passed to the puzzle for evaluation when a transaction is submitted. For more information about how transactions work, and how solutions can generate new coins check out this guide
 - CLVM - The CLVM is the ChiaLisp Virtual Machine which is the sandboxed environment that puzzles and solutions are run in. The CLVM only runs the compiled minimal version of ChiaLisp, though a compiler can convert the higher level ChiaLisp to the compiled minimal version. See more about that here
 - Aggregated Signature/AggSig - Aggregated Signatures allow us to condense multiple signatures into a single aggregated signature, such that if we know a public key and value we can verify if it exists inside of the single aggregate. This uses BLS non-interactive aggregation.
 - Prepend Signature - Prepend signatures are used so that we can retain metadata about the structure of an aggregated signature. TODO: Expand
 - Op Constraints/Conditions - Constraints are returned by the puzzle when it's passed the solution. If all of the returned conditions are met then a transaction is valid.
 - Wallet - Software written to interact with transactions. Chia uses Hierarchical Deterministic Wallets (HD Wallets). This means that they can generate many different public keys that are all valid and verifiable as unique to that wallet. A wallet contains a coin if it possesses the information necessary to unlock that coin and create a transaction which spends it.
 - Puzzle Generator - A wallet will use a Puzzle Generator to define how it wants to receive transactions. Most wallets will want to generate the standard transaction, however by storing a ChiaLisp program that generate a puzzle, all a Sending Wallet needs to do is ask the Recipient Wallet what its Program Generator is and then run that to create the puzzle to lock the coin up with.
 - Puzzle Generator ID - This is the hash of a wallet's puzzle generator. A wallet can do a hash-lookup and see if it already knows the source code for that puzzle generator. If not, it will request the full source code and store that information in its lookup table.
 - Smart Contract - A smart contract is a specialised ChiaLisp puzzle which locks a coin up and enables complex blockchain interactions.
 - Coloured Coins - Coloured Coins are a special kind of chia coin which are created by users. A coloured coin is a uniquely marked subset of chia which can't be forged and can be linked to other assets.
 - Authorized Payees - Authorized Payees is a smart contract that means that Wallet A can give Wallet B some money, but Wallet B is only allowed to spend that money in ways that Wallet A has explicitly authorised.
 - Decentralised ID - A decentralised ID is a smart contract that enables a wallet to act as an ID which can create messages to other IDs. Based on the work of the identity foundation.

For Success, You Have to Build Synergy
Statue of Lib Pyramid
We all know the United States of America as the only super power that has ever been but this is not true. Go back in history and study how many super power nations have been there. You will be surprised to find out that the continent that is now currently the poorest on planet earth was once a super power. Yes Africa. So what made Africa and or any other superpowers successful? The answer is simple, they build team synergy.
Think of the Roman Empire, British Empire which is also considered to be the most influential and effective superpower in history. On this post I am only going to focus on Africa as the then super power. Egypt a country that is today run by guns was once at the level of America in dominance and power. It ruled Africa and its neighboring countries mostly under the influence of kings and pharaohs.
We all have a dream of one day taking a trip to Africa to tour the stunning architectural work that was put in building the Egyptian Pyramids. These are some of the stamps of authority that we can trace about Pharaohs. Historical analysis tells us that the Egyptians built the Giza Pyramids in a span of 85 years between 2589 and 2504 BC.
It is estimated that some pyramids took up to 100,000 people to build yet it goes down in history that Pharaohs build the pyramids. One thing that these pharaohs knew was how to build team synergy. Thy knew that thy could not do it a lone and therefore they used other people to implement their dreams. Unfortunately most people who took part in building pyramids were slaves but nobody talks about them. Everybody thanks and wonders at the marvelous works of pharaohs yet I am sure they hardly placed a brick to build the most astounding architectural work in the history of the world.
Pharaohs dominated and oppressed people until they saw their dreams come true. In the world today, we do not have to practice that to see our dreams come true but we can pick a team of qualified people to implement our dreams for us. No successful person does it a lone. We need people and that is why human beings are social beings. There are some people who know more than we know, some are gifted in different fields that we are. Let us give them a chance to shine. This does not mean that we are going to be successful by randomly places people in our work environment.
We have to select the right people for the right jobs. One of the most important knowledge and wisdom every leader or entrepreneur should have is the ability to pick the right people for the right jobs. Just as Pharaohs picked wisely their architects, engineers and slaves who were strong, skilled and proficient, we also need to follow suit but with one thing in mind. That we have to create opportunity for growth to people who serve with us. Add value in their lives and not turn them to slaves.
Let them enjoy what they do, let them love their work place and above all motivate them to go extra miles. Treat your people with love because they are the ones who build team synergy that results into success. You need people, you can and will not do it a lone.

Whenever we give a demo of OpenAnnotate, clients always ask, "What happens when multiple users need to review a document at the same time?" OpenAnnotate has always supported having multiple users annotating a document at the same time, but a recent client has added functionality which broadcasts "live" the annotations and comments that users are making. This makes the review process in OpenAnnotate more collaborative. This post will outline some things to look for when evaluating your options for annotating/reviewing documents in your ECM repository.
We have had clients struggle with other annotation products and review processes in the past that did not allow more than one user to be reviewing a document at the same time. The "out of the box" functionality that is advertised for many ECM repositories to be able to perform a document "review" involves the following:
- Create a workflow to send to individual reviewers
- Each individual user must check out the document when it is their turn to review
- Perform their edits in the document (with or without track changes)
- Remember check back in the correct document
- Complete the workflow task
We have seen many clients struggle with this process because it involves multiple steps that users must remember to perform in order for the review to go smoothly. Some of the things that go wrong or problems with this approach are:
- Only one person can be doing their review at a time. This can add hours/days to the review process because each user must independently make their edits before the next user can review and make their comments.
- Users forget to check back in the document, leaving others locked out of doing their review
- Users forget to turn on "Track Changes" in the document, so other reviewers and authors don't know what was changed
- Reviewers "over-edit" the document since they are using the native editing application and tend to spend too much time editing fonts, changing design, wordsmithing
- Documents must go through many separate review cycles since the first reviewers don't get to see what the later reviewers changed in the document.
TSG has had success in rolling out our OpenAnnotate annotation tool because it addresses the following issues:
- Annotations are made using the Adobe XFDF specification allowing for documents to be viewed with their annotations inline
- Reviewers have a simplified toolset that lets them enter comments, draw lines/boxes/circles/arrows, highlight/strikethrough text. This lets them focus on the content of their review rather than the semantics of the tool.
- Annotations are made as a layer on top of the document allowing multiple reviewers to be making their annotations at the same time
The most recent enhancement to OpenAnnotate takes that last point one step further as it allows users to collaborate on the review process in real time without having to refresh the page to see if another user has made comments.
We have added a "Participants" pane to the interface that will show all users that are currently annotating the document, as well as expose a chat window to allow users to have an informal dialog during the review.
When annotations are being made, every user will immediately see the annotation appear on their screen. This allows users to make their comments at the same time as other reviewers and respond to each other's feedback. We have also expanded each annotation with a "reply" feature which allows an individual to reply to a highlight/strikethrough or other annotation.
Let us know your thoughts in the comments below.

The Sandal with the Nails
By Larry Fine
The Importance of Being Joyful on the Sabbath and Holidays
The pages of the Talmud are a sea of precious insights for our lives. One interesting discussion that was recorded in the Tractate of Sabbath is that which pertains to the case of the Sandal with Nails.
It seems that the Mishna mentions that one must not go out on the Sabbath with a sandal that has nails in it. The Talmud comes to explain the reason for forbidding this particular type of sandal.
Three scenarios are given:
First, Samuel says that the reason is that there were Jews who sought refuge from the various decrees which were made against them. They would hide in a cave to escape detection. Now according to Samuel, the sandal in question was made of wood with an upper covering of leather. The heal area and the toe area were exposed similar to an open toe slipper. The front was wider than the heal area and a because of this a person could mistakenly put the sandal on backwards.
Those Jews who hid in the cave would say, "who ever wishes to enter may do so, but who ever wishes to leave may not do so." The reasoning was that it was easy to see an enemy as one approached the cave and therefore upon sighting the enemy, the Jew would continue to walk but in another direction so that his friends in the cave would not be detected. But since one who desired to leave the cave could not see what was outside until he emerged and then was visible to the enemy; they therefore feared that if one person were to leave, he would be spotted and all would be endangered.
One day a person wearing a sandal of this type, but wearing it backwards as described above, entered the cave. When others looked out they saw his footprints, which since he had the sandal on backwards, appeared to them that some one had left the cave.
Fearing that the enemy had discovered their location and that they were soon to be attacked, there was mass panic in the cave. Many people were killed in the ensuing struggle to escape.
Rabbi Eloy, the son of Elazar, explained differently. He said that they were hiding in the cave and the enemy soldiers were marching on the rock which was the roof of the cave. The enemy was wearing sandal that were made with nails. The sound came into the cave. Again, panic ensued as the people feared that the enemy was coming to attack them. In that panic many people were killed as they struggled to escape.
Rami, the son of Yechezkiel, gave a different explanation. He said that the sandal with nails was more like cleats of golf shoes, where the nails were on the bottom and they protected the sole from wearing out. The Jews were hiding in a synagogue and they heard noises that sounded like the approaching enemy. The people panicked and in their attempt to run away they trampled on each other and many were killed.
From these occurrences, the mere sight of a sandal with nails was enough for Jews of that time to recall the disastrous evens that had transpired. This recollection of such a disaster caused people to become saddened. Although the sages did not forbid the wearing of sandals with nails in them during the week day, they instituted a decree that this type of sandals should not be worn on the Sabbath or on the Jewish festivals since these were times of joy and happiness.
Now although the Talmud continues to discuss in detail exactly what constituted a sandal with nails that the sages forbade us to wear, and what is not in the ban, we can see a very important principle here for us in regards to the Sabbath and the Jewish festivals.
The sages felt the need that the Sabbath and the Jewish festivals be days of joy and happiness. They saw that just looking at a sandal, an article of dress which possessed no inherent or intrinsic reason to forbid its usage, had become the source of depression for their time. Therefore the sages in order to keep the observance of the Sabbath and the Festival in the spirit in which G-d wanted us to keep them, made this decree that we not wear this particular sandal with nails.
The concept of joy and happiness is so important, especially for the Sabbath and the Jewish holidays that all which detracts and depresses must be refrained from. This is a central point in the Sabbath and holidays.
Although today the decree is not brought down in the Code of Jewish Law since it no longer causes us any discomfort or depression. However we may certainly learn from this the importance of avoiding those things which bring sadness such as speaking about unpleasant event.
In being careful about our speech, as well as our actions, our Sabbath and holidays will turn into a fountain of inspiration and joy that will bring us through those unpleasant events in the coming week and give us the fortitude to overcome difficulties from the past. Reading newspapers and books which discuss unpleasant subjects should be avoided.
The key is in your hands. Refrain from talking and reading newspapers on the Sabbath and festivals. When you turn your mind to G-d's literature and to His thoughts by praying devoutly and studying His Holy Torah on the Sabbath, then He will stand with you when you are doing your work during the coming week.

NGOs told to "explain themselves" – harassment or idiocy?
Four major NGOs – the International Women's Human Rights Centre La Strada Ukraine ; the Ukrainian Women's Consortium; the International Helsinki Human Rights Association; and the Ukrainian Helsinki Human Rights Union – have received an extraordinary letter from the State Registration Service.
The letter states that the Justice Ministry has passed on a number of complaints, listing the names of the people who sent them and the dates of the letters. The State Registration Service writes that the letters relate to the activities of the above-listed civic organizations – "the Organizations".
"The letters speak of protest against the activities of the Organizations which in planned and systematic fashion undermine the institution of the family in Ukraine, propagate anti-Ukrainian anti-moral and anti-constitutional ideas. The letter also stresses that the Organizations are propagandizing perverted lifestyles, gender, homosexuality, set children against their parents and teachers and destroy age-old moral and traditional values.
On the basis of Article 25 of the Law on Citizens' Associations, the Organizations must provide before 10.06.2012 the State Registration Service with an explanation regarding the issues raised in the complaints."
The letter is signed by the Deputy Head, I. Kukharenko
The authors of some of the "complaints" are known to people in at least one of the NGOs, however the main issue lies elsewhere in the response from the State Registration Service. What the "explanation" can be to such accusations is difficult to imagine, but it is still more difficult to understand how and on what grounds this State body is asking for such information.
Not to mention, why.

- Turn off aquarium lights.
- Dim the lights in the room where the shipping box will be opened. Never open the box in bright light – severe stress or trauma may result from sudden exposure to bright light.
- Float the sealed bag in the aquarium for 15 minutes (Fig. A). Never open the shipping bag at this time. This step allows the water in the shipping bag to adjust slowly to the temperature in the aquarium, while maintaining a high level of dissolved oxygen.
- After floating the sealed shipping bag for 15 minutes, cut open the bag just under the metal clip (Fig. B) and roll the top edge of the bag down one inch to create an air pocket within the lip of the bag. This will enable the bag to float on the surface of the water (Fig. C). For heavy pieces of live coral that will submerge the shipping bag, place the bag containing the coral in a plastic bowl or specimen container.
- Add 1/2 cup of aquarium water to the shipping bag (Fig. D).
- Repeat step 5 every four minutes until the shipping bag is full.
- Lift the shipping bag from the aquarium and discard half the water from the bag (Fig. E).
- Float the shipping bag in the aquarium again and proceed to add 1/2 cup of aquarium water to the shipping bag every four minutes until the bag is full.
- Net aquatic life from the shipping bag and release into the aquarium (Fig. F).
- Remove the filled shipping bag from the aquarium and discard the water. Never release shipping water directly into the aquarium.

 \$\begingroup\$ Shouldn't the expression be e^e^e^e...^n? Also, why is there a space after the :? \$\endgroup\$ – CalculatorFeline Jun 11 '17 at 17:10
 - \$\begingroup\$ _USER_ because this isn't code golf, it just needs to be under 100 bytes. \$\endgroup\$ – Cyoce Jun 17 '17 at 3:54
 - \$\begingroup\$ So? What's so bad about saving a byte so you can add another x() call? \$\endgroup\$ – CalculatorFeline Jun 17 '17 at 19:29
Ruby, 100 bytes, score-1 = fωω+1(n2)
Basically borrowed from my Largest Number Printable, here's my program:
->k{n=0;n+=1 until(H=->z,a=[0]*z{b,*c=a;z.times{z+=b?H[z,b==1?c:[b>1?b-1:z]*z+c]:z};z};H[n*n]>k);n}
Try it online
Basically computes the inverse of fωω+1(n2) in the fast growing hierarchy. The first few values are
x[0] = 1
x[1] = 1
x[2] = 1
x[3] = 1
x[4] = 2
And then it continues to output 2 for a very long time. Even x[G] = 2, where G is Graham's number.
 - \$\begingroup\$ But what about g(fω9001CK3) where f is FGH? \$\endgroup\$ – user75200 Jan 6 '18 at 19:58
 - \$\begingroup\$ _USER_ the fgh isn't well defined for uncomputable ordinals. \$\endgroup\$ – Simply Beautiful Art Jan 7 '18 at 13:09
 - \$\begingroup\$ FGH is well-defined for uncomputable ordinals, as they have fundamental sequences. It's just uncomputable. \$\endgroup\$ – user75200 Jan 13 '18 at 17:33
 - \$\begingroup\$ _USER_ No. Fundamental sequences are very arbitrary. I could define ω9001CK[x] = x to have a fundamental sequence of length ω9001CK, which is computable for finite x, but very likely not what you wanted. By "well-defined," I meant there isn't a standard fundamental sequence for uncomputable ordinals that everyone can agree on. \$\endgroup\$ – Simply Beautiful Art Jan 13 '18 at 18:48
 - \$\begingroup\$ While it's true that fundamental sequences aren't unique, a fundamental sequence for a countable ordinal is supposed to be of length ω. \$\endgroup\$ – Anders Kaseorg Feb 18 '18 at 2:22

Kind of calculates the sum 1/(n * log(n) * log(log(n)) *...), which I found from here. But the function ended up 101 bytes long so I had to drop the explicit number of iterations, and instead iterate as long as the number is greater than one. Example outputs for inputs of 10^i:
0 1

7 4.595525574477128
8 4.640390570825608
I assume this modified series still diverges but do now know how to prove it.
The third series actually requires a googolplex numbers of terms before the partial terms exceed 10.

p(Math.log) is approximately equal to log*(x).
p(p(Math.log)) is approximately equal to log**(x) (number of times you can take log* until the value is at most 1).
p(p(p(Math.log))) is approximately equal to log***(x).
The inverse Ackermann function alpha(x) is approximately equal to the minimum number of times you need to compose p until the value is at most 1.
If we then use:
p = g => f => x => x < 2? 0 : 1 + p(p(g))(g(f))(f(x))
then we can write alpha = p(Id)(Math.log).
That's pretty boring, however, so let's increase the number of levels:
p = h => g => f => x => x < 2? 0 : 1 + p(p(h))(h(g))(g(f))(f(x))
This is like how we constructed alpha(x), except instead of doing log**...**(x), we now do alpha**...**(x).
Why stop here though?
p = i => h => g => f => x => x < 2? 0 : 1 + p(p(i))(i(h))(h(g))(g(f))(f(x))
If the previous function is f(x)~alpha**...**(x), this one is now ~ f**...**(x). We do one more level of this to get our final solution.
 - \$\begingroup\$ "p(p(x => x - 2)) is approximately equal to log**(x) (number of times you can take log* until the value is at most 1)". I don't understand this statement. It seems to me that p(x => x - 2) should be "the number of times you can subtract 2 until the value is at most 1". That is, p(x => x - 2)' should be the "divide by 2" function. Therefore p(p(x => x - 2)) should be "the number of times you can divide by 2 until the value is at most 1"...that is, it should be the log function, not log* or log**. Perhaps this could be clarified? \$\endgroup\$ – mathmandan Jun 16 '17 at 19:32
 - \$\begingroup\$ _USER_ looks like I made a typo on that line, it should be p = f => x => x < 2? 0 : 1 + p(p(f))(f(x)), where p is passed p(f) like in the other lines, not f. \$\endgroup\$ – es1024 Jun 17 '17 at 3:39

Nowadays more and more older people compete with younger people for the same jobs
You should spend about 40 minutes on IELTS writing task 2.
Nowadays more and more older people compete with younger people for the same jobs. What can be the reasons for this? What would you suggest as a solution?
Give specific reason and explain them with examples from your own experience or knowledge.
You should write at least 250 words in IELTS writing task 2.
Question Overview
Topic : Job
Type : Reasons and Solution
Model Answer
Competition is indeed a significant mindset at a workplace which is more incidence between young and old employees. There are many reasons regarding this problem, and various measures could be taken by authorities to improve this situation.
More significant unemployment proportion along with the incursion of this innovative breakthrough would be the significant causes of increased competition amongst both old and young groups. Since individuals have confronted economic recession from the Earth, the unemployment rate is climbing, they are readier to keep the job they have, and kids compete with their older counterparts to find a fantastic job. At precisely the same time, due to the advanced technology, companies find the young generation more knowledgeable about higher qualifications. On the other hand, the feeling of competitiveness will appear at this stage because older adults believe that traditional and traditional methods are a lot more useful rather than substituted with novel ones.
Providing greater job possibilities and applying both young and old folks to train every other will be the keys to solving this dilemma. Governments must invest in generating job opportunities and employ or maintain the elderly who are experienced and skilled to prepare younger counterparts. Moreover, authorities can offer training classes for elderly employees to boost their technical understanding. As a result, older people may benefit from your younger to learn modern technology use at work.
In conclusion, the rivalry among the young and the elderly employees will likely be handled if both groups help each other to improve their weaknesses and to provide more job opportunities in society.

The Cook Islands are closely associated to New Zealand. Air New Zealand is the only air carrier that flies directly from the U.S. to the Cook Islands. As you will see below, the Cook Islands use the NZD as their currency.
Despite some 90,000 visitors a year to the capital island, Rarotonga, the Cook Islands are largely unspoiled by tourism. There are no high-rise hotels, only four beach buggies and very little hype. The Cook Islands offer a rare opportunity for an authentic island holiday.
There are a total of 15 islands in the heart of the South Pacific spread over 850,000 square miles with a population of approximately 15,000. The Islands most visited are Rarotonga and Aitutaki which are only 140 miles apart.
Cook Island History
Ru, from Tupua'i in French Polynesia, is believed to have landed on Aitutaki, and Tangiia, also from French Polynesia, is believed to have arrived on Rarotonga around 800 AD. Similarly, the northern islands were probably settled by expeditions from Samoa and Tonga.
Cook Island Climate
Cooled by the gentle breezes of the Pacific, the climate of these islands is sunny and pleasant. Roughly speaking, there are two seasons: from November through May the climate is hot and humid, and from June through October the climate is warm and dry. Most of the rain falls during the hot season, but there are also many lovely sunny days during these months, with refreshing trade-winds.
Cook Island Geography
The Cook Islands consists of two main groups, one in the north and one in the south. The southern group is nine "high" islands mainly of volcanic origin although some are virtually atolls. The majority of the population lives in the southern group. The northern group comprises six true atolls.
Cook Island Southern Group
Aitutaki, Atiu, Mangaia, Manuae, Mauke, Mitiaro, Palmerston, Rarotonga (the capital island), Takutea.
Cook Island Northern Group
Manihiki, Nassau, Tongareva (Penrhyn) also known as Mangarongaro, Pukapuka, Rakahanga, Suwarrow
Cook Island Time Zones
Rarotonga and Aitutaki are in the same time zone.
Cook Island Currency
New Zealand dollar.
Cook Island Language
English and Cook Island Maori.

Composting sites could generate odour nuisances in the environment if not operated optimally in terms of odour. The implementation of a continuous odour monitoring system, OdoWatch, based on e-nose technology allows operators to better understand how and when odour incidents occur and what actions can be taken to reduce emissions.
A continuous odour monitoring system, fitted with 5 e-noses, a weather station and an odour dispersion modelling software, was set up at one of the largest composting sites in Europe. Although several sources were identified from the beginning as being likely to generate odour nuisances, monitoring enabled the identification of the 0-3 week fermentation source as being responsible for 87% of the nuisances generated.
The operator's efforts reduced odour nuisances which had increased by more than 40% over a 6-month period and by nearly 75% after 2 years. The nuisance level in inhabited areas was, to start with, relatively low, but was greatly reduced by the operator's diligence, using measurements made by the OdoWatch system in real time, and by continuous improvement of the techniques used.

To celebrate this day, all the children were invited to come dressed anything Scottish.
During the day, each class carried out different activities:
The Bunnies listened very carefully to the story of the School's history and then decorated a cake with the school badge. They also learnt about Scotland, traditional meals and pipers.
The Bears received the visit of the piper, Oscar Llobenes, who showed them how to play a pipe.
The Lions and the Tigers began the day participating in the Primary Assembly, listening with interest to the school's history and the Primary Choir, and watching a group of primary girls dancing Scottish Dances.
We thank Oscar very much and Primary for their invitation to the Assembly.

USING YOUR SAUNA
PREPARING YOUR SAUNA FOR USE.
- If you have wood burning heater, make sure to remove the protective film of the heater chimney before heating.
- Check the Sauna before heating. No flammable objects must be left on or near the heater.
- Check that there is water in the water tank (if you are using it).
- Ensure that the Sauna door is unlocked and easy to open before using it. If necessary, sauna door must be adjusted by the customer.
- Do not mount any additional accessories or shelves above the heater.
- Turn the Sauna heater on.
- The thermometer should be located at head level in the Sauna. It should be further away from the heater, so it does not give a false reading.
- Wait for the Sauna to reach the required temperature (normally 80-90º C).
All users should be aware of the potential dangers and requirements prior to participation in the Sauna!
THINGS TO NOTE WHEN USING THE SAUNA
Enjoy the many health benefits of the relaxing heat of your Sauna. But remember: being inside the hot Sauna for long periods of time raises your body temperature, which may be dangerous, especially for those with a heart condition or other health risks. Generally, the
recommended time inside a Sauna is from 10 to 15 minutes. After a period of heating, take a 5 minute break and then repeat. Also:
- Familiarize yourself with the safety instructions and keep away from the heater when it is hot.
- Be very careful when moving in the Sauna, as the benches and floors may be slippery!
- The Sauna should not be used by pregnant women or very young children.
- Remove all jewelry before entering the hot Sauna.
Wood is a natural material and can change through time. Cracks of various sizes, structural or color changes are not the defects – rather, they are features of the wood. Natural wood (not impregnated) becomes grayish after being left untouched for a while. Later it can turn
blue and get covered with mold.
- Impregnate and paint the wood to protect the product from outside. We recommend to inspect Sauna every 6 month and evaluate need of re-impregnation, re-painintg.
- When not in use, keep a bucket full of water in the Sauna during summer.
- Doors of the Sauna must be adjusted regulary.
- You should keep the sauna ventilation open all the time, to allow it time to dry and air out to avoid mold.
- To remove bench stains, use a mild soapy water and a soft cotton cloth. This can also be used on the heater itself - just make sure it's off and completely cool when you clean it.
- Don't use harsh or abrasive chemicals on benches, as these can bleach and warp the wood, ruining the grain and turning it grey.
With these simple maintenance tips your Sauna will stay inviting, fresh, and enjoyable!

Cost per order (CPO), sometimes called cost per acquisition, is the dollar amount spent on advertising or marketing in order to end with a sale. The cost per order is an important part of any web-based business, especially those which are just staring out, or have a very strict budget. The cost per order price is figured by dividing the marketing expenses by the number of orders that the company prepares, and can be used to evaluate the effectiveness of a certain type of marketing, as well as seeing what type of marketing is working well with the targeted consumer demographics.
Cost per order figures are used in decision making for Internet companies. It can have an effect on many different parts of the company, from the employee benefits to how much the products cost. Some of the decisions that can be made based on cost per order figures include:
How much to pay employees who put products together or get them ready to be shipped
What types of equipment for product production can be used or purchased
Shipping methods that can be used to get orders to customers in a timely manor
The price asked for a product
The types and amount of marketing that can be used and utilized
While cost per order is a very important part of Internet businesses, there are experts that also suggest taking cost per order information with a grain of salt. The numbers can be misleading because they do not take into account factors like decision making time on the part of the consumer.

Girl opens fire in high school Idaho
A student of a high school in the U.S. state of Idaho has opened fire on fellow students. Two kids and a janitor were injured before a teacher could disarm the girl.
The shooter, who would be around 12 years old, had taken the firearm in her backpack. At the beginning of the class day, she started shooting. Its not yet known what her motive is.
We were in class with our teacher and suddenly we heard a loud bang, and then twice more. Then there was screaming, says a schoolmate. Our teacher went to look and saw blood lying down.
Hit in limbs
The three victims were hit in limbs. None of them are in mortal danger. The 1500 students of high school have been given free to deal with the incident.
Shootings are more common in American schools, but in the state of Idaho they are rare: the last time a student fired a weapon in a school was in 1999, when one fellow student was injured by a ricochet bullet.

Pinwheels for Peace at Timber Point
Students at Timber Point Elementary School in East Islip celebrated the International Day of Peace on Sept. 21 by creating "Pinwheels for Peace" and participating in various other Peace Day projects and activities. According to Principal Lisa Belz, the purpose was to "recognize, understand and help create a culture of peace."
"The fifth grade in particular created their own quotes for peace, listened to and analyzed the words of Martin Luther King's 'I Have a Dream' speech, learned how to say 'peace' in many languages, and designed Pinwheels for Peace which are displayed on the bulletin board in the hallway," said Timber Point teacher Carol Wilson.
The International Day of Peace, also unofficially known as World Peace Day, has been observed every Sept. 21 since 1982 and is dedicated to the concept of peace, specifically the absence of war and violence.

I'm not sure how to go about finding the solution to this question.
Let R be a ring with identity such that $x^2 = 1_R$ for all $0_R \neq x\in R$. How many elements are in $R$?
I've just been playing around with squaring elements, like $$(x+1_R)^2 = x^2+2.x+1_R =2.x+2.1_R = 1_R.$$
But I'm not sure where to go with this. Any help?

Either $1_R+1_R=0$ or $(1_R+1_R)^2=1_R$ so $3\cdot 1_R=0$. – Davide Giraudo Mar 5 '12 at 20:15

One possibility, of course, is $R=\{0\}$. Assume $1_R\neq 0$.
$R$ has no zero divisors: if $xy=0$ and $x\neq 0$, then $y = 1_Ry = xxy = x(0)=0$.
$R$ is commutative: if $x$ and $y$ are nonzero, then so is $xy$ by the above; hence $(xy)^2 = x^2y^2$; canceling from $xyxy=xxyy$ we get $yx=xy$.
(Of course, the ring satisfies $x^3=x$ for all $x$, so by a famous theorem of Jacobson, the ring is necessarily commutative; but we don't need to call in that heavy cannon to the fray).
Since every nonzero element is invertible, $R$ is a field. Since $x^2-1_R$ has $|R-\{0\}|$ solutions, we have $|R-\{0\}|\leq 2$, so $|R|\leq 3$.
If $1_R+1_R=0$, then $R$ is of characteristic $2$, so $R\cong \mathbb{F}_2$ and $|R|=2$. And, indeed, in this case the hypothesis holds.
If $1_R+1_R\neq 0$, then we get $4\cdot 1_R = 1_R$, hence $3\cdot 1_R=0$, so $R$ is of characteristic $3$, and therefore $R\cong\mathbb{F}_3$ and $|R|=3$. Again, the hypothesis holds for this ring.
In summary, $R$ has either $1$, $2$, or $3$ elements, and is either the trivial ring, $\mathbb{F}_2$, or $\mathbb{F}_3$.

Thanks, this is very helpful, but why does $x^3=x$ imply that $R$ is commutative? – 098765 Mar 5 '12 at 20:28
_USER_: It is a common exercise in Ring Theory, and also a consequence of a famous Theorem of Jacobson, which states that a ring for which there exists $n\gt 0$ such that $x^n=x$ for all $x$ is always commutative. But I gave a simpler derivation that does not call upon such heavy artillery in an edit. – Arturo Magidin Mar 5 '12 at 20:33
_USER_ am pleased you revised your answer, because the proof that $x^3 = x$ implies R is commutative isn't trivial, and is probably beyond the stage at which the asker of this question is at. – David Wheeler Mar 5 '12 at 20:53
Does your proof actually depend on commutativity? (mine does not). If not, then you can omit the proof of comutativity, since it's a trivial consequence of the final result. – Bill Dubuque Mar 5 '12 at 22:42
_USER_: I use commutativity only to conclude that I have a field rather than a simply division ring; I believe it is equivalent to your "$x^{-1}=x\Rightarrow R$ field". – Arturo Magidin Mar 6 '12 at 3:54

$\rm R=0\:$ works. Else $\rm\ x\ne 0$ $\Rightarrow$ $\rm x^2 =1$ $\Rightarrow$ $\rm x^{-1} = x $ $\Rightarrow$ $\rm R$ field, so $\rm\: x\ne 0\!\iff\!\! (x-1)(x+1) = 0$ $\iff$ $\rm x=\pm 1.\:$ But $\rm\: R\backslash0 = \{\pm1\}$ $\!\iff\!$ $\rm R\:\! \cong\:\! \mathbb Z/2\:$ or $\:\mathbb Z/3$.
More generally, the finite fields $\:\rm\mathbb F_p,\: \mathbb F_q,\ p,q\:$ prime, are axiomatized by the ring axioms plus $$\rm x^n =\: x,\quad n\: =\: 1 + lcm(p\!-\!1,q\!-\!1)$$ $$\rm q\:(x^p-x)\: =\: 0\: =\: p\:(x^q-x)$$ $$\rm pq\: =\: 0$$
Thus any identity true in both of these fields has a purely equational proof from the above axioms. This theorem extends similarly to any finite set of finite fields, for example see Stanley Burris and John Lawrence, Term rewrite rules for finite fields (1991). This result is very closely related to Jacobson's model-theoretic proof of commutativity of rings satisfying the identity $\rm\: x^{n_x} =\: x$.

Mainframe Skills are Desirable in the Workplace
A recent survey by Compuware is one of the latest reports to confirm that organisations are facing a serious mainframe-skills shortage. The survey has found that the CIOs of many organisations are concerned about a looming shortage of mainframe-qualified people in the workforce. This shortage presents an opportunity for those looking to study or work in the IT field, and suggests that mainframe skills will be highly sought after in the job market.
Driving factors
The Compuware survey of 350 organisations around the world showed that the key driving factor behind the expected shortage is the impending retirement of those with mainframe skills and experience.
Around two-thirds (66%) of CIOs were concerned that the trend would negatively impact their business by harming the capacity of their organisation to use and maintain legacy applications. As many as 61% believed it to be a primary concern. Some 61% of respondents said that there would be an increase application risk. The same number of respondents believed that it would lead to lower productivity, while 51% believed that there would be a higher incidence of project overruns.
The survey found that while CIOs were concerned, many organisations had no specific plan for address the risks associated with the retiring mainframe workforce and the lack of a replacement workforce.
Some 40% of CIOs stated that they had no formal plan in place to address the risks. However, this appears to be an improvement on the previous survey in 2011, which found that 46% of CIOs had no specific plan in place.Hence, those with the necessary mainframe skills and experiences are closer to retirement age; yet, many organisations are not acting on the issue with a proactive strategy.
The vital role of mainframe systems
Mainframe systems are commonly used in industries such as banking, finance and telecommunications. Organisations in these industries typically run their core applications on mainframes.
The Compuware survey found that 81% of CIO respondents held the belief that mainframes will still be a major business asset in the coming decade. According to Kris Manery from Compuware, mainframes are complex to manage. Effective management requires experience and familiarity with mainframe systems, which Manery said can take up to two years for new developers to attain.
Skill shortage presents an opportunity
The mainframe skills shortage could be viewed as an opportunity for developers and other IT specialists seeking to work in the field. Mainframe skills are required in a spectrum of organisational areas, including operations, database administration, help desk, security and more.
As Manery highlighted, it can take a matter of years for newer IT specialists to gain the necessary mainframe expertise. The majority of CIOs surveyed in the study confirmed that mainframes will function as key business assets in the decade to come. As such, mainframe skills will probably continue to be highly desirable and sought after in the job market.

 Something that was much insisted on when I was at school, because i guess some kids found it hard to get their heads round. Like 1M HCl or NaOH are 1N but 1M H2SO4 or Na2CO3 are 2N. You get the idea? - it's the same as the distinction between molar masses and equivalent masses (or weights as we used to call them).
 I think they have been phased out of teaching now, have they? If so it's no loss, they are unnecessary.

 Normality meant different things at different moments in time. There was a period when normality depended on the reaction - so 1M sulfuric acid was 2N in the reaction with NaOH, but 1N inteh reaction with CaCl. Then IUPAC decided to make it always reaction with H+ or e- - so 1M sulfuric acid would be always 2N. Then, IUPAC decided they created so much confusion it is better to deprecate normality at all.

Three Ideas for Recruiting Non-Profit Volunteers
KPM non-profit header link to blog.
02 May Three Ideas for Recruiting Non-Profit Volunteers
Most charitable non-profits have a never-ending need for volunteers. Finding new ones can be time-consuming, and volunteer searches are not always successful. Here are three recruitment ideas that can help.
 1. Look nearby
Is your non-profit familiar to businesses, residents, and schools in the surrounding community? People often are drawn to volunteer because they learn of a worthwhile organization that is located close to where they live or work.
Make the effort to get to know your neighbors by performing an inventory of the surrounding area. Perhaps there is a large apartment building you have never paid much attention to. Consider the people who live there to be potential volunteers. Likewise, if there is an office building nearby, learn about the businesses that occupy it. Their employees might have skills, such as website design or bookkeeping experience, that perfectly match your volunteer opportunities.
Once you have identified some good outreach targets, mail or hand-deliver literature introducing your non-profit as a neighbor and describing your needs. Consider inviting your neighbors to a celebration or informational open house at your offices.
 1. Fine-tune your pitch
By making your pitches as informative and compelling as possible, you are more likely to inspire potential volunteers to action. Specifically, explain the:
 - Types of volunteer jobs currently available
 - Skills most in demand
 - Times when volunteers are needed
 - Rewards and challenges your volunteers might experience
When possible, incorporate photographs of volunteers at work along with their testimonials. Also, make it easy for people to take the next step by including your contact information or directing them to your website for an application.
 1. Reach out to your network
Develop a system for keeping those closest to your organization — major donors, board members, and active volunteers — informed of your volunteer needs. These individuals often are influential in their communities, so a request from them is more likely to gain attention. They may even frame a request for assistance in the form of a challenge, with the solicitor being the first to volunteer their time or funds, of course.
Remain in pursuit
No matter how precise or thorough your initial recruiting efforts, remember that one-time or sporadic efforts are insufficient to attract a steady supply of volunteers. To get the resources you need, make volunteer recruitment a continuous process that draws on several strategies.

Leveraging transformers for effective and efficient retrieval
Abstract: While relatively recent, transformer architectures like BERT (Bidirectional Encoder Representations from Transformers) have already demonstrated their ability to substantially improve effectiveness across a wide range of text ranking tasks. The increased effectiveness of these approaches is not without drawbacks, however, and the architecture of these models both comes with significant efficiency costs and creates challenges for applying them to text ranking. In this talk I will describe where and how transformers can be leveraged for text ranking, discuss some of my work tackling the challenges of applying transformers to this task, and describe some of the remaining challenges and what they mean for applying transformers to text ranking today.
About the Speaker: Andrew Yates is an assistant professor at the University of Amsterdam, where he focuses on developing content-based neural ranking methods and leveraging them to improve search and downstream tasks. He has co-authored a variety of papers on pre-BERT and BERT-based neural ranking methods as well as an upcoming book on transformer-based ranking methods. In 2016 Yates received his Ph.D. in Computer Science from Georgetown University, where he worked on information retrieval and information extraction in the medical domain.

Abstract : The use of parameter plane curves of output voltage magnitude versus one of the parameters as a means of obtaining the frequency response of nonlinear networks was investigated for networks containing one nonlinear element, which was a function of the magnitude of the voltage across it. The results obtained were checked by digital simulation and it may be concluded that the method is reliable. The method was also presented as a way of obtaining information for the reshaping of network frequency response by introduction of the proper nonlinear elements. (Author)

Strategic lobbying and taxation choice : a political economy of trade policy analysis
In this thesis, I use a political economy of trade policy approach to analyze the issues of strategic lobbying and taxation choice. The thesis contains 4 papers together with an introduction, literature review and conclusion. In Chapter 3, a lobbying-influence model is presented to discuss how the outcomes of trade policy is influenced by lobbying activities during the policymaking process. A comparison of the welfare-maximizing model and the lobbying-influence model under a game theory framework is undertaken. Chapter 4 provides a new explanation on the issue of asymmetric lobbying from the view point of the impact of external environment. Since the incentive of the domestic firm to engage in lobbying activities varies with its marginal costs, the outcomes of lobbying performance are different. This argument holds for both complete and incomplete information settings. Chapter 5 considers whether there is a positive role for lobbying activities in an incomplete information setting when the foreign entry is incorporated. The results suggest that the social welfare under the pooling equilibrium is higher than that under the separating equilibrium. As a result, there is no positive role for lobbying activities in this two-period model. Chapter 6 provides a political economy model to explain why trade taxes rather than more efficient income taxes might be adopted and what links the taxation choice and the economic development. In general, people prefers to pay less tax to the government. In a democratic society, a policy, which yields a higher utility to the majority of voters, is supported through majority voting. Therefore, the choice of taxation instruments depends on the tax payments, which are determined by the tax method, the income level, and the movement of income distribution over time.
