memory at any given time is known as memory capacity.
How much memory is there in a human brain?
Your storage capacity could be limited to a few megabytes, about equal to that of an iPod or a USB flash drive. However, neurons work together such that each one contributes to several memories at once, exponentially boosting the brain's capacity for memory storage to closer to about 2.5 petabytes (or a million gigabytes).
How uncommon are eidetic memories?
The odd but actual perceptual phenomenon known as eidetic memory, which affects between 2 – 15% of children and very infrequently adults, is sometimes mistaken for a photographic memory. A vivid afterimage that persists in the mind's eye for up to a few minutes before dissipating is known as an eidetic image.
What distinguishes eidetic memory from photographic memory?
Photographic memory is the capacity to recall a picture with great precision over a considerably more extended period than eidetic memory, which can only do so briefly. This is the main distinction between photographic memory and eidetic memory.

New Alias (Alias Tab)
An alias is an alternate name that can be used to make a connection. The alias encapsulates the required elements of a connection string, and exposes them with a name chosen by the user. Use the Alias page on the Alias - New dialog box to specify the elements of the connection string for an alias. To change the connection string of an existing alias, see Properties (Alias Tab).
All values in the Properties grid do not have to be completed. Valid combinations vary depending on the protocol selected. See the topics listed below for examples of valid combinations.
By default, SQL Server connects to a local instance of SQL Server using the Shared Memory protocol, and to an instance of SQL Server on another computer using either TCP/IP or Named Pipes. Create an alias when you are using TCP/IP, named pipes, or VIA, and you want to provide a customized connection string, or when you want to use a name other than the server name for the connection.
SQL Server is not listening on the default TCP/IP port of 1433 so you want to provide a connection string with a different port number.
SQL Server is not listening on the default named pipe so you want to provide a connection string with a different pipe name.
An application expects to connect to a database on the server named ACCT, but that database has been consolidated as an instance named ACCT on a server named CENTRAL. The application cannot easily be changed. Create an alias named ACCT, with a connection string pointing to CENTRAL\ACCT.

Step 1: Make the Rig
You will want to dig this in the hottest part of the ground you can, not shade.
Step 2: Pee in Your Hole
Once you have this up and running for real, you can take the poncho off and the container out any time you have to pee.
Might as well put it to use than peeing on a tree, dont you think?
Step 3: Put the Container in the Middle of the Hole
Step 4: Place the Plastic Over the Hole
A side note is, it is a good idea to use some of the soil to cover the edges, thus sealing it from critters and such, and keeping it weighed down a bit on the edges.
Step 5: Place a Rock/soil in the Middle of the Poncho
Step 6: Wait
You won't get a full waterbottle, but you will get some, which isn't such a bad deal, concidering you dont have to put any effort into it other than building it.
Step 7: How This Works
What happens is, the sun's heat evaporates only the pure water from the moist soil. The water vapor rises to the poncho where it condenses into water drops. After a while of this, the water drops build up and roll down the the middle of the poncho where they then fall into the container.
This gives you pure water from your urine.


Bach and Books
You can expose your students to classical music while they are reading quietly in a reading area by letting them listen to music on portable cassette players or CD players. Your public library likely has recordings to check out, and is a wonderful way to introduce them to something they likely have no knowledge of at all.

The Aircraft Particle Emissions eXperiment (APEX) was conducted at NASA's Dryden Flight Research Center April 2004 to afford the scientific community an opportunity to systematically investigate the emissions of a commercial-class aircraft, NASA's DC-8, during ground-based operation. APEX included participants from more than ten institutions, each providing unique measurement capabilities for trace gas and/or particle species.
JETS APEX2 was conducted at the Oakland International Airport in August 2005 to was to develop TOG and PM speciation profiles for engines used in older (CFM56-3) and newer (CFM56-7) Boeing 737-type commercial aircraft burning standard Jet A fuel.
The main objective of APEX3 was to advance the knowledge of aircraft engine particle emissions. APEX3 was conducted at Cleveland Hopkins International Airport (CLE) from October 26 to November 8, 2005. In APEX3, as in the previous studies, engine exhaust emissions and plume development were examined by acquiring data from the exhaust nozzle and in the near-field plume from a range of stationary commercial aircraft.

Insight into plant behavior could aid quest for efficient biofuels
Researchers at the University of Edinburgh have found that the tiny organism has developed coping mechanisms for when its main food source is in short supply.
Understanding these processes will help scientists develop crops that can survive when nutrients are scarce and to grow high-yield plants for use as biofuels.
The alga normally feeds by ingesting nitrogen from surrounding seawater but, when levels are low, it reduces its intake and instead absorbs other nutrients, such as carbon and phosphorus, from the water. The organism is also able to recycle nitrogen from its own body, breaking down proteins that are plentiful to make other proteins that it needs to survive.
Nitrogen is needed by all plants to survive but the alga's survival strategies vary from most other plants which, when nitrogen is scarce, tend to widen their search for it.
Like many organisms, the alga Ostreococcus tauri is also driven by daylight and its body clock for example, proteins that produce starch for food are active in the evening, after the plant has photosynthesised sugars from sunlight in the day.
The study, in the Journal of Proteomics, was funded by the Biotechnology and Biological Sciences Research Council and the Engineering and Physical Sciences Research Council.
Dr Sarah Martin, of the University of Edinburgh, who took part in the study, said: "This tiny alga certainly punches above its weight when it comes to survival. Our study has revealed some curious ways in which the organism finds the nutrients it needs to stay alive tricks like these could be useful to us in developing sustainable crops for the future."

October 3, 2011 | A team that includes NCAR scientists Anne Boynard and Alex Guenther has found that the rate at which plant canopies emit isoprene, a volatile organic compound, is influenced by circadian rhythms. The discovery has the potential to lead to more accurate predictions of ground-level ozone, which is harmful to human health.
For the study, the researchers made measurements of isoprene in Malaysia above both tropical rain forest and oil palm plantations. They observed for the first time ever a circadian (24-hour) rhythm operating in concert across the entire tree canopy, especially in the palm plantation.
The finding changes how scientists estimate isoprene emissions from plants, as both the palm plantations and rain forest emit less isoprene than shown by computer models of emissions. This has implications for ground-level ozone, which forms when volatile organic compounds such as isoprene react with nitrogen oxides from automobiles and industry.
The researchers incorporated the circadian pattern into the NCAR Model of Emissions of Gases and Aerosols from Nature (MEGAN) model to estimate isoprene emissions for input to ozone models. They then compared simulated ground-level ozone to observed ozone measurements from 290 monitoring sites in the United States. They found that model accuracy was significantly improved. Accounting for circadian impacts on isoprene emissions could especially improve ozone predictions in isoprene-sensitive regions of the world, which include the United States, Mediterranean, Middle East, Japan, and parts of Southeast Asia.
The research was published in Nature Geoscience in September.

Country France
Language Silent
L'Arroseur arrosé (also known as The Waterer Watered and The Sprinkler Sprinkled) is an 1895 French short black-and-white silent comedy film directed and produced by Louis Lumière and starring François Clerc and Benoît Duval. It was first screened on June 10, 1895.
It has the distinction of being the earliest known instance of film comedy, as well as the first use of film to portray a fictional story. The film was originally known as "Le Jardinier" (The Gardener) or "Le Jardinier et le petit espiègle", and is sometimes referred to in English as "The Tables Turned on the Gardener", and "The Sprinkler Sprinkled".
Shot in Lyon in the spring of 1895, the film portrays a simple practical joke in which a gardener is tormented by a boy who steps on the hose that the gardener is using to water his plants, cutting off the water flow. When the gardener tilts the nozzle up to inspect it, the boy releases the hose, causing the water to spray him. The gardener is stunned and his hat is knocked off, but he soon catches on. A chase ensues, both on and off-screen (the camera never moves from its original position) until the gardener catches the boy and administers a spanking. The entire film lasts only 49 seconds, but this simple bit of slapstick may be the forerunner of all subsequent film comedy.[1]
In the earliest years of the history of film, the cinema was used by pioneers such as Thomas Edison and the Lumières to entertain by the sheer novelty of the invention, and most films were short recordings of mundane events, such as a sneeze, or the arrival of a train. Ever seeking to innovate, the Lumières took some of the first steps toward narrative film with L'Arroseur arrosé. Given the documentary nature of existing films up until this point, a scripted, comedic film shown among these was unexpected by an audience, enhancing its comedic surprise value.[1]
It was filmed by means of the Cinématographe, an all-in-one camera, which also serves as a film projector and developer. As with all early Lumière movies, this film was made in a 35 mm format with an aspect ratio of 1.33:1.[2]
Louis Lumière used his own gardener, François Clerc, to portray the gardener. For the mischievous boy, Lumière used a young apprentice carpenter from the Lumière factory who is variously credited as Daniel Duval and Benoît Duval.[3] But Léon Trotobas seems to have been the first boy to play the role in La Ciotat.[4]
The poster[edit]
The world's first movie poster, for 1895's L'Arroseur Arrosé
The poster for L'Arroseur arrosé has the distinction of being the first poster ever designed to promote an individual film. Although posters had been used to advertise cinematic projection shows since 1890, these early posters were typically devoted to describing the quality of the recordings and touting the technological novelty of these shows.[5] The poster for L'Arroseur, illustrated by Marcellin Auzolle, depicts an audience (in the foreground) laughing as the film (in the background) is projected against a screen. It depicts the moment the gardener is splashed in the face, and is thus also the first film poster to depict an actual scene from a film.[5]
Copies and Imitations[edit]
As copyright law was neither enforced nor yet well-defined for the emerging art of cinema, it was common both for competing filmmakers to reshoot a popular film short and for distributors to duplicate a film print to show as their own. Through these practices, L'Arroseur arrosé was copied several times and released under a number of different titles in both France and the US, including at least one remake by the Lumières, themselves.[6] Little is known about most of these copies, although one known remake was filmed by Georges Méliès, titled L'Arroseur, in 1896.[1] French New Wave director François Truffaut later included an homage to the gag in his 1958 film, Les Mistons.[1]

Uniqueness in Interchange
In order to process message flows in a coherent and predictable manner, Interchange enforces the uniqueness of object names.
Unique object names
In order to configure Interchange, you create objects and assign values to attributes of these objects.
As a general rule, each object that you create in the Interchange interface must have a unique name.
Object creation: If you try to create an object with a name that already exists, Interchange displays a message informing you of the naming conflict and instructing you to enter a unique name.
Object importing: If you import an object or set of objects with a name that is already used in a configuration, the importer executes one of the following actions to insure uniqueness:
 - ignore - ignores the imported object and conserves the existing object
 - replace - replaces the existing object with the imported version of the object
 - update - modifies the existing object by adding, deleting or revaluing attributes from the imported object
Upgrades: If you upgrade from a previous version, the upgrade logic never deletes previous data. When the upgrade logic detects or must generate a potentially duplicated object, it automatically renames the duplicates with unique names. In some cases it may also have to disable the renamed object to conserve the functional uniqueness of the configuration.

THE EMERGENCE OF A NEW OWNERSHIP AND LEGAL-ORGANISATIONAL STRUCTURE OF AGRICULTURAL PRODUCERS IN RUSSIA (Ksztaltowanie sie nowej struktury wlasnosciowej i prawno-organizacyjnej producentow rolnych w Rosji)
The democratic and market reforms inaugurated in Russia in the early 1990s marked also the beginning of a spontaneous process shaping a new legal-organisational structure of agricultural producers. The basis for the start of this process was the agricultural reform (de-collectivisation of agriculture) providing for the apportionment of arable land to the farm workers by means of the so-called stakes (some 12 million persons) and for the restructuring of kolkhozes and sovkhozes. The principal tendencies that characterise this process are: firstly, the formation - chiefly on the basis of the former kolkhozes and sovkhozes, of a new organisational-legal structure of agricultural enterprises based on private ownership, secondly, the emergence and development of a new group of agricultural producers (farmers) and, thirdly, the strengthening of an extremely large group of household crofts which have a very long tradition in Russian agriculture. The process is reflected also in the changing structure of land and labour resources and, consequently, in the structure of agricultural production which changes under the influence of the emerging forms of husbandry. The principal tendency in this process is growth in the number of private farms and household crofts and a decline in the number of agricultural enterprises.

Pierre Corneille, the French dramatist, was born in Rouen in 1606. After a Jesuit education he worked as Crown Counsel in Rouen, and for many years kept playwriting as his leisure activity. He wrote tragedies and comedies, and his first success came in 1636 with Le Cid, a tragi-comedy which made Corneille's reputation as a master of serious drama and established the genre known as French classical tragedy. During the next forty years Corneille produced over twenty-five plays. He died in 1684.

NDSU Associate Professor Researches how North Dakota Crops Can Be Used by Food Manufacturers
January 30, 2012, Fargo, N.D. – If you have ever been curious about where the idea for your breakfast cereal or snack food originated, it may have been in a lab like the one at Harris Hall where Clifford Hall conducts his research.
Hall, associate professor in the School of Food Systems and interim technical director of the Northern Crops Institute, researches how North Dakota crops, such as beans, peas and flax, can be used in nontraditional ways.
Grinding dried beans, puffing them and coating them with cheese, for example, produces a food similar to Cheetos, which are made from corn, he explained. And protein from peas can replace eggs in baked goods such as cakes, cookies and muffins. "Most people don't think of peas and eggs functioning the same way, but they can in baking applications," Hall said.
The advantage of using dried beans in snack food is the high fiber, micronutrient and protein content that starchy snacks lack, Hall said. He sees commercial potential for bean-based snacks in Southeast Asia where consumers prefer natural foods. "Products made from beans and peas are of interest because these commodities are currently produced using traditional agricultural methods," Hall said.
People who have egg allergies and vegans are possible consumers for products that replace eggs with pea protein. If a product doesn't contain eggs, the food manufacturer can leave the egg allergen warning off the food label, Hall said. Pea protein is also less expensive than eggs.
But does pea-protein cake taste good? "The sensory evaluations have been positive," Hall said. "They are comparable to egg cake." In November 2011, Hall invited people on campus to taste test cookies and cake made with the pea protein instead of eggs. In physical measurements, products made from eggs fared better; however, taste testers liked the baked goods made from pea protein more than the cakes made with eggs. "The moist texture was one reason why panelists liked the cakes containing pea protein," Hall said.
Hall, who has a sensitivity to eggs, uses pea protein in his own kitchen for pancakes, waffles and muffins. "I'm a guinea pig to my own research," he said.
The goal of Hall's research isn't to produce a commercial product, but to prove that the ingredients can be made into an affordable food that looks and tastes good. Food manufacturers then use the research to develop the products consumers see in stores. About a decade ago, for example, Hall and Frank Manthey researched using flax in pasta. Since then, food manufacturers have developed flax-enriched pasta.
His research on bean-based snack foods and pea-protein as egg replacer bodes well for North Dakota farmers. North Dakota is the No. 1 producer of dried peas and several types of dried beans.

Chronic abdominal pain (caP) refers to pain that has been present continuously – or occurring at least on a weekly basis when intermittent – for a minimum period of 2 months. it is a description not a diagnosis, and can be due to a functional disorder or organic disease. a functional disorder is one in which symptoms of disease occur in the absence of objective evidence for an organic process. in the majority of cases, caP in childhood is due to a functional disorder. a detailed history should elicit the characteristics of the pain, precipitating and relieving factors, appetite, dietary intake, and stool history. in the well child with a normal examination and history typical of functional caP, investigation is usually unnecessary. However, the duration and severity of pain, its impact on daily life and the level of concern will temper this approach.


Reply To: Tip: simulate post grid (for specific pages)
Jason Bobich
This is sort of tough to do from the custom query option because in all ways (that I know of anyway) to specify specific pages would not be possible within a single string.
I can think of two ways where actually feeding pages through to the post grid would be possible the way things are setup.
1) Take the pages you want to be in the post grid and set them as Child pages to some Parent page. Then in your custom query string you'd do this:
Where "123" is the numerical post ID for the Parent page, to which you want the child pages below it to show. Note that by using the custom query string in any post grid, you're overriding the number of posts normally generated for you based on the columns/rows. So, you need to specify that, as well.
2) Now, this is super hacky, but an interesting thing I just thought of. Internally, there is a filter on the query string every time a post grid is generated. But there's no way to really identify this filter with a specific post grid instance.
In your instance of the Post grid, you could use the "query" option to pass in some unique identifier to use as a "catch" from your PHP function that you're going to attach to the filter for all post grid queries.
So, for example, setup a post grid and for the query option write something like:
Now from your Child theme's functions.php you can filter onto the query string for all post grids and use that identifier to trigger some custom query string.
 * Custom query for post lists/post grids
function my_custom_posts_query( $query, $args ){
 if( $args['query'] =='my_unique_key' ){
 $query = array(
 'post_type' => 'page',
 'post__in' => array( 1, 2, 3, 4 ) // ID's for any pages you want to include
 return $query;
add_filter( 'themeblvd_posts_args','my_custom_posts_query', 10, 2 );

Computes and Transmits Meaningful Data
- Computes and sends 6 running dynamics metrics to your compatible device
- Battery life: replaceable battery lasts up to 1 year (assuming 1 hour daily use)
- Automatically turns itself on and off
- Tiny size: at less than 0.5 ounces, you'll forget it's there
- Compatible devices connect with the Garmin Connect Mobile app to automatically sync your data and connect with others
Train Hard, Run Free
The Running Dynamics Pod easily clips onto your waistband to measure the running dynamics you need to beat yesterday. It gives you the option to run without a heart rate monitor chest strap. Once paired with your compatible smartwatch, just clip it to the back and center of your waistband and start your run.
Review Your Form
View and analyze important running metrics such as your cadence, stride length, ground contact time and balance, vertical oscillation and vertical ratio. These biomechanical measurements can help you understand your running form so you can perform better on race day.
How It Works:
The Running Dynamics Pod has an accelerometer in the module that measures torso movement to calculate these 6 running metrics:
- Cadence is the number of steps per minute. It displays the total steps (right and left combined).
- Ground contact time balance displays the left/right balance of your ground contact time while running. It displays a percentage. For example, 53.2 with an arrow pointing left or right.
- Stride length is the length of your stride from 1 footfall to the next. It is measured in meters.
- Vertical oscillation is your bounce while running. It displays the vertical motion of your torso, measured in centimeters for each step.
- Vertical ratio is the ratio of vertical oscillation to stride length. It displays a percentage. A lower number typically indicates better running form.
- Ground contact time is the amount of time in each step that you spend on the ground while running. It is measured in milliseconds.

We here report a rare presentation of bilateral anterior dislocation of shoulder with associated fracture of greater tuberosity in a 38 year old male due to minor trauma which he sustained secondary to hyponatremia induced irritability. There was no associated rotator cuff tear which is often associated with BADS which makes this presentation unique. Unilateral dislocation of shoulder is a common condition which is frequently encountered in emergency trauma department. Anterior dislocation is more common than posterior dislocation. However, simultaneous bilateral shoulder dislocations are usually posterior. Bilateral anterior dislocations with fractures of the greater tuberosity are even rarer and are usually associated with trauma or seizures.

Are Paper Checks Still Relevant?
Are Paper Checks Still Relevant?
With the rise of debit cards, paper checks can seem slow and outdated. After all, checks work much like a debit card, allowing the recipient to redeem the check for the stated amount, although the actual transfer of funds can take longer. While there is an argument that paper checks are no longer relevant or useful, they are still in use, primarily by adults over the age of 55, with checks accounting for 15 percent of all non-cash payments in one of the latest studies reported by the Federal Reserve. Checks are still heavily used for large money transactions, such as payroll and rent.
Here's a brief look at the benefits and drawbacks of paper checks and why they still have a place in today's online-dominated marketplace.
Pros of Paper Checks
No payment solution is best for every situation. For example, debit and credit cards, while convenient, can come with a higher risk of identity theft and higher costs for merchants. The following are the most important benefits that paper checks can offer.
 - Many businesses do not accept cards. Credit card processing can be expensive and not every business can afford this cost. Forbes reports that 55 percent of the 27 million small businesses in the U.S. do not accept credit cards. That is especially true with micro-merchants, such as landscapers and pool cleaners, who do not have the volume to justify payment processing costs. With some bills such as rent to a landlord, a check is the only way to make a payment.
 - Easy person-to-person payments. There are now many ways to send money to a private individual, such as Square and PayPal. Despite their convenience, there is not a single payment option that dominates the others. A personal check offers a convenient and accessible way to pay a private individual who does not need to do anything special to receive the money.
 - Check use creates a paper trail. When you use a check, it automatically creates a paper trail that documents when proof of payment was received. Checks are the best way to prove that a lender, creditor, or government agency received payment.
 - Checks can be post-dated. A check works like a contract, stating that the person the check is written out to is to be paid the specified amount on the date noted on the check. Post-dating a check can work for both parties. The person who writes the check knows it cannot be cashed before a specific date.
 - Payment can be stopped. While some banks charge a fee of up to $35, you can stop payment on a check. That is not an option with other payment methods.
Cons of Paper Checks
There are many reasons that paper checks remain relevant, but they are not without drawbacks.
 - Overdraft potential. One of the primary disadvantages is it can be easy to overdraft an account without careful balancing of your checkbook. If you bounce a check, you can face a fee from your bank as well as the check recipient.
 - Merchants do not always take checks. It can be harder to find merchants who are willing to accept checks today, especially out-of-state checks or checks from unfamiliar banks. Merchants also face risks by accepting checks. It may be days before the merchant is alerted that the check was fraudulent or that the check was rejected due to insufficient funds.
 - Security concerns with some checks. There can also be security issues with personal checks. When you give someone a check, you are providing them with your account number, name, and contact information on the check. A check payment can also be used to begin electronic debits which give the merchant greater access to the payee's bank account to make unauthorized but legal debits.
The days of paper checks dominating the payment landscape are gone, but paper checks are still relevant. Check payments offer benefits not available with other payment options, including the ability to post-date a payment, stop a payment, and create an easily traced paper trail for recordkeeping.


Computes the difference between two lists of numbers or strings.
Given a list x and a list y, this operation returns a list out that represents all values that are in x but not in y. The returned list out is sorted in the same order that the numbers appear in x (duplicates are preserved). This operation also returns a list idx that represents the position of each out element in x. In other words:
out[i] = x[idx[i]] for i in [0, 1,..., len(out) - 1]
For example, given this input:
y = [1, 3, 5]
This operation would return:
out ==> [2, 4, 6]
idx ==> [1, 3, 5]
x A Tensor. 1-D. Values to keep.
y A Tensor. Must have the same type as x. 1-D. Values to remove.
name A name for the operation (optional).
A tuple of Tensor objects (out, idx).
out A Tensor. Has the same type as x.
idx A Tensor of type out_idx.


Let $F(k,n)$ be the number of permutations of an n-element set that fix exactly $k$ elements.
We know:
 1. $F(n,n) = 1$
 2. $F(n-1,n) = 0$
 3. $F(n-2,n) = \binom {n} {2}$
 4. $F(0,n) = n! \cdot \sum_{k=0}^n \frac {(-1)^k}{k!}$ (the subfactorial)
The summation formula is obviously
$\displaystyle\sum_{k=0}^n F(k,n) = n!$
A recursive definition of $F(k,n)$ is (my claim):
$$F(k,n) = \binom {n} {k} \cdot \Big( k! - \displaystyle\sum_{i=0}^{k-1} F(i,k) \Big)$$
Question 1: Is there a common name for the "generalized factorial" $F(k,n)$?
Question 2: Does anyone know a closed form for $F(k,n)$ or have an idea how to get it from the recursive definition? (generating function?)
The "semi-exponential" generating function for these is
$\sum_{n=0}^\infty \sum_{k=0}^n {F(k,n) z^n u^k \over n!} = {\exp((u-1)z) \over 1-z}$
which follows from the exponential formula.
These numbers are apparently called the rencontres numbers although I'm not sure how standard that name is.
Now, how do we get a formula for these numbers out of this? First note that
$$exp((u-1)z) = 1 + (u-1)z + {(u-1)^2 \over 2!} z^2 + {(u-1)^3 \over 3!} z^3 + \cdots $$
and therefore the "coefficient" (actually a polynomial in $u$) of $z^n$ in $exp((u-1)z)/(1-z)$ is
$$ P_n(u) = 1 + (u-1) + {(u-1)^2 \over 2!} + \cdots + {(u-1)^n \over n!} = \sum_{j=0}^n {{(u-1)^j } \over j!} $$
since division of a generating function by $1-z$ has the effect of taking partial sums of the coefficients.
The coefficient of $u^k$ in $P_n(u)$ (which I'll denote $[u^k] P_n(u)$, where $[u^k]$ denotes taking the $u^k$-coefficient) is then
$$ [u^k] P_n(u) = \sum_{j=0}^n [u^k] {(u-1)^j \over j!} $$
But we only need to do the sum for $j = k, \ldots, n$; the lower terms are zero, since they are the $u^k$-coefficient of a polynomial of degree less than $k$. So
$$ [u^k] P_n(u) = \sum_{j=k}^n [u^k] {(u-1)^j \over j!} $$
and by the binomial theorem,
$$ [u^k] P_n(u) = \sum_{j=k}^n {(-1)^{j-k} \over k! (j-k)!} $$
Finally, $F(k,n) = n! [u^k] P_n(u)$, and so we have
$$ F(k,n) = n! \sum_{j=k}^n {(-1)^{j-k} \over k!(j-k)!} $$

 - $\begingroup$ Not necessarily. It's not hard, though; I'll edit the solution to explain that. $\endgroup$ – Michael Lugo Dec 21 '09 at 16:57

Although that last one is not a huge number, if you take all three together, it's plenty standard enough for a relatively obscure concept. $\endgroup$ – Greg Kuperberg Dec 21 '09 at 17:38

 $\begingroup$ My claim that the name was nonstandard was entirely subjective; basically, this is something that I felt I should have known a name for, and the name was new to me. $\endgroup$ – Michael Lugo Dec 21 '09 at 17:50
A permutation of {1,..., n} with k fixed points is determined by choosing which k elements of {1,..., n} it fixes and choosing a derangement of the remaining n-k elements. So,
$F(k, n) = {n \choose k} F(0, n-k)$.
(This formula is also on the page Michael Lugo linked to.) You have already given one formula for the number of derangements on n letters. Another one is F(0, n) = the nearest integer to n!/e.
Various links on this answer have expired, so I thought I would add an answer.
One can use inclusion--exclusion. First, note (as in _USER_'s answer) that $$ F(k,n) = \binom kn F(0,n-k). $$ So it is sufficient to only study permutations with no fixed points. This is known as the number of derangements. Various proofs using inclusion--exclusion can be found on Wikipedia:

From Wikipedia's article on JSON
SyntaxError: Unexpected token ILLEGAL? That doesn't make any sense! It's just a regular object literal, how can that be a SyntaxError?
Try the same code in a proper JSON parser. No problems at all.
Of course it's not just a regular object literal. There's a sneaky little Unicode character in there too: Right between "ro" and "cks!" there's a tiny U+2028. Your browser probably doesn't display it because it's whitespace: LINE SEPARATOR, but it's still there. If you replace the character with a U+2029 (PARAGRAPH SEPARATOR) you would have the exact same issue.
JSON + U+2028 = ☺
According to the JSON specification, you can safely use this character in any string. It's not a quote, not a backslash, and not a control character. It's just a weird Unicode whitespace character:
DoubleStringCharacter :: SourceCharacter but not double-quote " or backslash \ or LineTerminator \ EscapeSequence SingleStringCharacter :: SourceCharacter but not single-quote'or backslash \ or LineTerminator \ EscapeSequence
And what is a line terminator? Let's have a look at 7.3 Line Terminators:
The following characters are consider to be line terminators:
\u000ALine Feed
\u000DCarriage Return
\u2028- Line separator
\u2029- Paragraph separator
In most applications, you won't notice this issue. First of all, the line separator and the paragraph separator aren't exactly widely used. Secondly, any proper JSON parser will have no problems with parsing it.
Luckily, the solution is simple: If we look at the JSON specification we see that the only place where a U+2028 or U+2029 can occur is in a string. Therefore we can simply replace every U+2028 with
\u2028 (the escape sequence) and U+2029 with
\u2029 whenever we need to send out some JSONP.
It's already been fixed in Rack::JSONP and I encourage all frameworks or libraries that send out JSONP to do the same. It's a one-line patch in most languages and the result is still 100% valid JSON.


Initial review of the matter - stage one
To support agencies apply the CaPE Case Categorisation Framework, a three stage approach to assess and manage conduct and performance matters has been developed. The approach supports the proactive and timely resolution of matters.
In stage one, a manager, human resources or ethical standards area in an agency receives information about a conduct or performance matter, to conduct an initial review to determine the details of the matter, the issue type and whether the matter should be categorised under the CaPE reporting framework.
A comprehensive intake process that includes all relevant information to hand at the time the matter is referred will ensure that all available information is considered and will allow for planning to occur about how to manage the matter to finalisation, within benchmark timeframes.
During the initial review of the matter, the following aspects should be considered by the assessor:
Intake considerations
Issue The specifics of what the matter is actually about, or the high level descriptor of the concern/s
Behaviour Does the behaviour relate to an employee's conduct or their performance? Does the employee know what is expected of them?
Breach What is the breach of policy, procedure or accepted standards of behaviour?
Evidence What information is available to support the matter at the time it is raised, consider any gaps in the information that may exist.
Referral Whether the matter, if proved, would constitute corrupt conduct.
Issue type Consider the issue type that most closely aligns to the circumstances of the matter.
At any point during the initial review or ongoing management of the matter, should a reasonable suspicion be formed that if proven, the allegations may constitute corrupt conduct, and the matter must be referred to the Crime and Corruption Commission (CCC). Each agency has a designated CCC Referral Officer who is responsible for this function and can provide advice about the management of corrupt conduct. Matters involving corrupt conduct are not reportable in an agency's CaPE report unless the employee has been suspended from duty.
1. Determine the issue type
This issue type register below provides a descriptor for each issue type. To select the most appropriate issue type, consider the descriptor in conjunction with the specifics of the matter.
To support local management of the matter, the assessor may deem it necessary to assign multiple issue types. However, for CaPE reporting purposes the single most appropriate issue type must be assigned to the matter i.e. one issue type.
2. Issue type register
Determining the appropriate issue type is dependent upon the specific circumstances of each matter, which should be assessed in its own context, with regard for the allegation/s and information available at the time the matter is raised.
Issue type Descriptor
Assault/excessive force Can involve matters defined as assault in section 245 of the Criminal Code Act 1899, or use of excessive force with or without a weapon. Can also include threats of assault or excessive force.
Attendance/leave Matters involving unauthorised absence from the workplace or those where a pattern of unscheduled absence has been noted.
Breach of scope of practice Includes matters where a health practitioner may have undertaken a task outside of their education, registration conditions or departmental policies.
Bullying/harassment (not sexual) Repeated unreasonable behaviour towards an employee or group of employees that creates a risk to the health and safety of the employee/s.
This does not include reasonable management action or an employee's perception of reasonable management action being taken against them.
Charge/conviction (civil) Information obtained that an employee has breached a civil law.
Charge/conviction (criminal) Information obtained that an employee has been charged or convicted with an offence under the Criminal Code Act 1899 or other relevant legislation.
Conduct in a private capacity Inappropriate or improper conduct in a private capacity that reflects seriously and adversely on the Queensland Public Service.
Conflict of interest The private interests of an employee interfere, or appear to interfere with the employee's performance of duties, and the employee has not declared or managed the conflict appropriately.
Discrimination Treatment of a person or a group of people less favourably than others because they have a particular characteristic as outlined in section 7 of the Anti-Discrimination Act 1991. Discrimination can be direct or indirect.
Drug/alcohol issues Can involve possession or theft from the workplace of an illicit or prohibited substance or related paraphernalia. It can also involve matters where an employee presents for work whilst impaired by alcohol or drug use
Failure to provide adequate medical treatment Care or treatment provided by the practitioner is at a lesser standard than what may reasonably be expected of the practitioner according to relevant standards, codes of practice, and/or by the public or the practitioner's peers. Can also relate to circumstances where an employee responsible for the care or welfare of others does not seek or provide medical assistance where required.
Failure to show courtesy and respect Behaviours demonstrated towards another in the course of duty that contravene the standards contained in the Code of Conduct.
Financial impropriety/fraud Can include matters involving the fraudulent diversion of public funds (including the fabrication of information or dishonesty in claiming employee entitlements), theft of public funds or unauthorised use of public funds (including government resources such as work time, equipment or facilities). Can also include matters involving a dishonest attempt to obtain a benefit or entitlement.
Inappropriate conduct (general) A general behaviour that is inappropriate that may not contravene the Code of Conduct but may still give rise to corrective actions occurring.
Inappropriate conduct (sexual) Conduct or unwelcome attention of a sexual nature that makes a person feel offended, humiliated or intimidated. Includes uninvited physical intimacy, uninvited sexual propositions and remarks with sexual connotations.
Misuse of resources Matters included in this category can involve unauthorised or inappropriate use of physical, intellectual, service or Information Technology based public resources, but does not include financial impropriety.
Non-compliance (direction) A deviation occurring from a lawful and reasonable instruction or direction issued to an employee in the course of their duties.
Non-compliance (policy/legislation) A deviation from an agency's or a profession's standards, policies or legislation relevant to the carrying out of the employee's duties.
Non-disclosure of relevant information The deliberate withholding of information relevant to an employee's employment or the carrying out of their duties.
Performance deficiencies Can include performance matters that are being informally dealt with through feedback to the employee, matters that are being managed through a performance improvement plan (PIP) or that are being managed through a discipline process if a PIP is unsuccessful. This type of issue includes deficiencies resulting from a lack of knowledge, competence or appropriate care or diligence but do not include deliberate acts or omissions in duty.
Unauthorised access/disclosure of confidential information
Can involve accessing or disclosing official information without a legitimate reason, unintentionally disclosing official information, falsifying information or records, acquiring or retaining information or records illegally, or inadequately safeguarding information.
Note - issues involving unauthorised access to information or departmental databases will likely involve a breach of the criminal code and require referral to the QPS and/or the CCC.

Besides its presence on the Iberian Peninsula, Portugal encompasses the Azores Islands of the Archipelago, one of which is the Flores Island. This land mass is covered with forests in the center, but ringed with sandy beaches and covered in pink and purple hydrangea flowers. Flores lies nearly 1,000 miles to the west of Lisbon in the middle of the Atlantic Ocean. The Portuguese colonized the islands in the mid-15th century. Often invaded by pirates, the islands eventually became an important part of Atlantic trade, serving as a stopping point for planes and cruise ships. They are known for their fishing industry, tropical fruit, wine, and cheeses.
Azores Flores, far out in the sea, is an unlikely home to dairy cows, but the Portuguese saw the lush fields and forests and realized the potential for cattle rearing. The farmers now promote Azores Flores, a pasteurized cow's milk cheese, aged for three months, with a strong, clean, spicy taste and aroma.
While this cheese is not overly aged, its history dates back to seafaring times. The islands were known for their high quality, fragrant milk. The farmers made fresh cheeses meant to be eaten straightaway in the port, but for those on a long journey, they made firmer cheeses that could travel the distance.

DSS works to ensure accommodated quizzes, tests, and exams for students registered with DSS and who have testing accommodations. Other requests will be considered on a case-by-case basis and will depend on the current demands and workload of the DSS office.
The Accommodated Testing Process is as follows:
 1. Students with testing accommodations will request to take a test with DSS via "DSS Test Request" Google Form.
 1. One request must be made for each test.
 2. Students are required to make the request at least seven (7) days before a test is to be scheduled. If requested later than this deadline, it is not guaranteed that the student will be able to take the test with accommodations.
 3. If there are any changes to the request (e.g. test date) or if there are any concerns, please email _EMAIL_ immediately.
 2. Seven (7) days before the scheduled test, DSS will notify the instructor via email that their student has requested to take a test with DSS and will ask them to reply with test details.
 1. Instructors should respond within at least 2 days of receiving an email from DSS.
 2. Instructors will be asked for the following test details:
 1. Date and time of the test
 2. Duration of the test
 3. Test platform (Blackboard, Examsoft, etc., or in-person)
 4. Emergency phone number
 3. If there are any updates to test parameters, please email _EMAIL_.
 4. Note: Because DSS is responsible for ensuring testing accommodations are in place, it is critical that faculty respond to our accommodated testing emails, even if proctoring services are not needed. If a professor's failure to respond to DSS about testing accommodations becomes habitual, DSS will contact the Dean or Department Chair to address this matter.
 3. DSS will work with the instructor to ensure that testing accommodations are in place. When the exam is confirmed, DSS will send the student a calendar invite for the proctored exam.
 4. If a student wants to change the date and/or time of the test, students must email DSS (_EMAIL_) and the instructor to engage in the rescheduling process. DSS will work with the student and instructor to coordinate the rescheduled test.
Proctoring Information for Faculty
DSS will offer an option of Zoom and in-person proctoring for all students with testing accommodations whose professors are also Zoom/in-person proctoring their classmates (who do not have accommodations). If students without accommodations are not being proctored, DSS cannot proctor students with accommodations.
DSS Zoom Proctoring Schedule:
 - Monday: 2-5pm
 - Tuesday: 9am-12pm, 2-5pm
 - Wednesday: 9am-12pm, 2-5pm
 - Thursday: 2-5pm
 - Friday: 9am-12pm, 2-5pm
Please note the following regarding proctoring sessions:
 1. Each test proctoring session will take place via Zoom/in person; each proctored test session will have a limited capacity, likely including students from different classes.
 2. All students will be required to begin at the same time in order to minimize distractions during testing time.
 3. Some students may not be taking their exam proctored by DSS at the same time as their classmates. DSS will work to place students in a proctored time slot as close to their classmates as possible without missing other classes.
 4. DSS cannot guarantee student placement in a given test slot.
 5. DSS will assist with Comps/Hesi proctoring on a limited basis this semester. Any request for DSS proctoring for Comps/Hesi must submit a request at least 30 days in advance for consideration. DSS will work with the faculty and/or dean to determine whether DSS can provide proctoring.
Please note the following regarding proctoring scheduling:
 1. For the proctoring option to be successful, DSS will require professors to communicate their proctoring needs well in advance of the testing date, in order to coordinate student scheduling with proctoring times.
 2. When DSS emails faculty regarding a student's accommodated test request, it is imperative that professors respond as soon as possible, especially if they wish to request proctoring.
 1. Specific deadlines will be included in the student accommodated test emails sent to faculty.
 2. Faculty who do not adhere to these deadlines will no longer be able to engage DSS for proctoring and will need to proctor their own exams.
 3. DSS is not able to provide technical support for any lockdown browser issues.
 4. DSS is not able to control student submission of tests when they finish.
Please email DSS at _EMAIL_ if you have any questions.

|Quercus ilex L.|
The Holm oak (also called Holly oak, Evergreen oak) is a large evergreen oak tree native to the Mediterranean region. Its botanic name is Quercus ilex L. The name ilex was the original (Roman) Latin name for this tree, but botanists have now used it for the holly genus.
A typical tree has ridged bark and leathery leaves. The leaves fall in June in the northern hemisphere, after new leaves emerge. Leaves are usually dark green above, and greyish and downy below. The leaf shape is variable on any tree, but those borne on lower branches and on young trees are often toothed or somewhat spiny. This is presumed to be for protection from grazing animals. In this, the foliage resembles that of the common European holly, (Ilex aquifolium), and this resemblance has led to its common and botanic names.
While it is can be grown in much of maritime northern Europe, it is not tolerant of cold continental winters. It can be clipped to form a tall hedge, and it is suitable for coastal windbreaks, in any well drained soil. It forms a picturesque rounded head, with pendulous low-hanging branches. Its size and solid evergreen character gives it a imposing architectural presence that makes it valuable in many urban and garden settings.

Existence of Positive Solutions for Multipoint Boundary Value Problem on the Half-Line with Impulses
© J. Li and J.J. Nieto 2009
Received: 7 March 2009
Accepted: 25 April 2009
Published: 4 June 2009
We consider a multi-point boundary value problem on the half-line with impulses. By using a fixed-point theorem due to Avery and Peterson, the existence of at least three positive solutions is obtained.
Impulsive differential equations are a basic tool to study evolution processes that are subjected to abrupt changes in their state. For instance, many biological, physical, and engineering applications exhibit impulsive effects (see [1–3]). It should be noted that recent progress in the development of the qualitative theory of impulsive differential equations has been stimulated primarily by a number of interesting applied problems [4–24].

Boundary value problems on the half-line arise quite naturally in the study of radially symmetric solutions of nonlinear elliptic equations and there are many results in this area, see [8, 13, 14, 20, 25–27], for example.
They showed the existence at least three positive solutions for (1.4) by using a fixed point theorem in a cone due to Avery-Peterson.
Yan, by using Leray-Schauder theorem and fixed point index theory presents some results on the existence for the boundary value problems on the half-line with impulses and infinite delay.
However to the best knowledge of the authors, there is no paper concerned with the existence of three positive solutions to multipoint boundary value problems of impulsive differential equation on infinite interval so far. Motivated by [20, 25], in this paper, we aim to investigate the existence of triple positive solutions for BVP (1.1). The method chosen in this paper is a fixed point technique due to Avery and Peterson.
In this section, we give some definitions and results that we will use in the rest of the paper.

Pinned: Never Change Streams in the Middle of a Horse
Did I ever tell you about the little red corpuscle who was swimming in the bloodstream of a horse?
This little corpuscle was always in a hurry. One day, he decided to play hooky from the school of red corpuscles, so he told his teacher he had a headache.
Well, this was a mistake. As he swam down the main artery, using the Australian crawl, he came to a fork in the stream - it was high tide.
The little red corpuscle took the fork on the starboard side. He proceeded to swim lazily down the new stream when disaster suddenly struck!
The little red corpuscle was swallowed by a huge virus.
The virus' name was Cyrus.
Thus, our moral: Never change streams in the middle of a horse!

This template shows how simple it is to use latest technologies to build a nice modern reactive web application comprising of a Client-side JavaScript App built using EmberJS and WebSockets with WebGL ThreeJS, served from the Play 2 Framework written in Scala which works high velocity data from different sources using Play Iteratees and Akka. One of the main goals of this template is to show how such non-trivial application can be written very quickly, elegantly, readably and scalably with just a few lines of code using the Typesafe technologies and to describe and discuss the concepts, technologies, various alternatives that are provided to programmer to meet the goals, provide resources for further education and to help even beginners to start with or improve in using these technologies.
In the beginning it doesn't look very interesting. But we will get there.
Reactive applications are aiming to resolve the latest needs in software development. Even web is quickly moving towards the features of the Reactive Manifesto. The ability to react quickly to user's interaction is becoming more and more important. This activator template illustrates how a real time communication can be simply, reliably and scalably built on the Typesafe platform. The template uses Play 2.3 and utilizes Iteratees as an useful abstraction to handle continuous streams of data in form of real time bidirectional websocket communication as well as Akka Actor web socket interface. Other technologies used are Scala, Play, Akka and Scalaz for server backend and Ember.js, HTML5 device orientation API, Bootstrap and Three.js for front end and visualisation as well as some other smaller tools that will be mentioned in the documentation.
Main functionality of the Play server is to act as a router for web socket messages. It accepts connections on two different web sockets. The first web socket receives messages with data about spatial orientation from an arbitrary number of mobile devices. Web sockets in combination with orientation data serve as a good descriptive source of data with reasonably high volume and velocity so we can show how these can be handled using the Typesafe platform. The server applies transformation function to each message and merges streams of messages from all devices into a single stream which is in turn sent to the other websocket where the data for each individual device are clearly displayed in real time. This is illustrated on the figure below.
Go to Run tab in Activator and start the application and then visit http://localhost:9000. Another option is to start the application from linux terminal using activator run command for Play 2.3. After the application startup, you will be presented by the Dashboard page and IP address of the machine in network. This is because you will need to connect to the Play server from other devices. In real life the application would be deployed in the internet so you would just need to enter the url. This case however requires you to enter the local network address, including port (default 9000) to your mobile device's browser - for example When the page is loaded, select Device tab and click the Start button. If the device supports orientation sensor, it should start sending data to the server. The Dashboard page will show real time information including visualisation of the device's orientation. Each device connected will be presented individually. After certain time of inactivity the device is removed from the Dashboard. Note the visualisation may not be exactly correct, because the alpha represents the angle to north so you may need to adjust your screen with Dashboard manually.
System overview - Server
Play controller
The main work of the application happens in Application.scala. This object is the only Play Controller in the whole application. It has three methods. The index method attempts to retrieve network interfaces to be able to present the IP address and then presents index.scala.html view. The most elegant way is to use play actor sockets (introduced in Play 2.3) for connections from mobile devices and Iteratees/Enumerator for dashboard sockets. You can read about both options in Play scala web sockets. The controller has one instance of Enumerator and one instance of Channel. Messages pushed to the Channel will be received by web sockets using the Enumerator. This is important to understand, because these will be shared by actors that will push messages to the Channel and device websockets who will use the Enumerator.
val (dataEnumerator, dataChannel) = Concurrent.broadcast[JsValue]
Method mobileWebSocket is triggered when a new web socket connection is started from the mobile device. When using actor sockets, Play automatically creates one actor for each connection on the web socket. This is a very convenient way to scale - because actors can run in parallel and have nicely distributed responsibility - having as much actors as devices won't create a performance bottleneck or a single point of failure.
 def mobileWebSocket = WebSocket.acceptWithActor[OrientationChangeEvent, JsValue] { request => out =>
 Props(new StreamMergingActor(dataChannel))
Play automatically sends a message to the specified actor when a message on the web socket interface is received. The type of the message is specified by the first type parameter of acceptWithActor function.
It would be possible to achieve the same using Iteratees and Enumerators approach. The code would then look for example like this.
 def mobileWebSocket = WebSocket.using[OrientationChangeEvent] { request =>
 val in = Iteratee.foreach[OrientationChangeEvent] { mergingActorRouter! _ }
 val out = Enumerator.empty[OrientationChangeEvent]
 (in, out)
In this case, we would however need to take care of the number of actors manually. One solution would be for example to create a Router that distributes incomming messages according to predefined logic. One option to create a router would be to add one actor to the routees with each connection or create a router with a fixed number of actors equal to number of cpu cores available on the machine.
 lazy val mergingActorRouter = Akka.system.actorOf(
 .props(Props(new StreamMergingActor(dataChannel))))
Method dashboardWebSocket manages web socket connections from dashboard page using Iteratee and Enumerator. Iteratee is a representation of incomming message stream and Enumerator of the outgoing. The code handling web sockets from dashboard using Iteratees and Enumerators may look like this.
 def dashboardWebSocket = WebSocket.using[JsValue] { request =>
 (Iteratee.ignore, dataEnumerator)
This solution is very elegant and minimal, because we again use Play to do the hard work. We just use the same channel for each incomming websocket connection. When a message is received from mobile device, the actor that is responsible for handling the message will simply push it to this channel and because it is shared by all Dashboard web sockets, they will automatically all receive the message. In addition, this abstraction very nicely illustrates the intended functionality - messages from multiple devices are merged into one stream! Notice also the Iteratee is ignored (because we are not expecting any messages from the dashboard apart from initial web socket connection). Again this is not the only option and it would be possible implement the same logic using Actor web sockets, but we would have to manually handle the fact that the response is not going to the same socket as the received message.
To summarize the above solution - one actor is created for each Device connection. All these actors push messages the same shared output channel which in turn is also shared by all Dashboard connections.
Scala's ecosystem offers a variety of options to handle this use case. One notable alternative to Play would be for example Spray.
Akka actor
The application only uses one user defined actor located in StreamMergingActor.scala. StreamMergingActor's role is to merge incomming streams from devices and send the resulting stream to dashboards using the share channel. Companion object StreamMergingActor defines messages which the actor understands. OrientationChangeEvent and OrientationChangeData represent one single message received from the mobile device. Each message contains deviceId, information about the device, assigned colour and three values - alpha, beta and gamma - which represent the orientation data and will be explained later. Most important fact is,

"Decolonizing Design Research" is a workshop series that explores how research can create spaces and places that reflect values of anti-racism and justice. The dominance of western design aesthetics and research methods is largely invisible to those who were trained in design. As a result, these practices can reinforce existing power structures that are harmful to many. This workshop series will provide a space to understand how to mitigate bias in design research methods and learn about less familiar methods used in other disciplines and contexts.
Who creates and benefits from knowledge?
How are the actions and findings from research communicated?
What research or data underpins an impactful social movement?
Workshop participants will gain insights from academic and applied research about methodologies that can be linked to shifting power and working toward liberation. Prior attendance in this series is not required to participate in this program.

10 Common Questions for Pop Warner Parents
Signing your child up for Pop Warner football is exciting and overwhelming at the same time.
Like any new adventure, playing Pop Warner football will come with lots of questions. Will my child be safe? How big are the kids playing on my child's team? When can I register? What league will my child play in?
Here are some frequently asked questions first-time Pop Warner parents ask, and some answers to get you started as your child embarks on a great experience.
Is there a league in my area?
Pop Warner has football leagues in 42 states from coast to coast, so chances are there's one in your area. Visit Pop Warner's league finder web page to find information--including contact information and web addresses--of the Pop Warner league near you.
When are sign-ups?
It depends on the league, but usually are in the spring and summer months. Check the website of your local league for more information.
What are the different age groups?
Pop Warner has opportunities for players ages 5-15, and they are separated into nine divisions. The youngest, the Tiny-Mite division, features children ages 5-7. The Bantam division features 13-15 year olds with 16-year olds welcome if they are light enough.
My child has a birthday during the season. How does that affect age placement?
With Pop Warner games being played in the fall, the organization has set up a specific guideline: A child's age on July 31st is his/her age for the entire season. So if your son turns 10 on August 1st, he will still be considered a 9-year old for registration purposes.
Does my child's weight matter?
Yes, it does. Pop Warner combines age restrictions with weight restrictions to make an age/weight scale. It is as follows:
 - Tiny-Mite: Ages 5-7. Must be between 35 and 75 pounds.
 - Mitey-Mite: Ages 7-9. Must be between 45-90 pounds.
 - Junior PeeWee: Ages 8-10 must be between 60-105 pounds. 11-year olds are accepted if they weigh between 60-85 pounds.
 - PeeWee: Ages 9-11 must be between 75-120 pounds. 12-year olds are accepted if they weigh between 75-100 pounds.
 - Junior Midget: Ages 10-12 must be between 85-135 pounds. 13-year olds are accepted if they weigh between 85-115 pounds.
 - Midget: Ages 11-14 must be between 105-160 pounds. 15-year olds are accepted if they weigh between 105-140 pounds.
 - Junior Bantam: Ages 12-14 must be between 120-170 pounds. 15-year olds are accepted if they weigh 120-150 pounds.
 - Unlimited: For 12-15 year olds who weigh more than 170 pounds.
 - Bantam: Ages 13-15 year olds who weight 135-185 pounds. 16-year olds can play if they are between 135-165 pounds.
For more information, check out Pop Warner's Age/Weight structure web page.
Are there any other requirements?
Pop Warner demands academic excellence among its participants. Players must receive a 2.0 grade-point average (or 70 percent average) in school to participate. Exceptions are made through Scholastic Eligibility Forms, which are filled out by that child's school to determine whether Pop Warner football would be beneficial to that child.
Are there tryouts?
No. Everyone is allowed to participate and play. All you have to do is sign up.
Is my child safe playing organized football?
Though injury is always possible in any sport, Pop Warner is quick to point out that injury rates are significantly lower in youth football than in high school or college football. That's partly because of Pop Warner's strict age/weight scale that makes sure all the children are playing against players their own size.
Studies have shown that organized football among children produces fewer injuries than soccer.
How many games will my child play?
The regular season schedule is usually between seven and nine games, between late August and late October. Playoffs will follow in certain divisions, and the best teams will play in the Pop Warner Super Bowl in Florida in early December.
If my child isn't the best player on the team, will he/she just sit the bench all season?
Not at all. Pop Warner has mandatory rules of play that requires everyone be able to participate. That means that every player will get in for several plays every game.

Teach For All
Teach For All exists to address global educational needs and enable students to realize their full potential. A child's background often determines their educational and life prospects. Poverty, discrimination, social mobility and political structures create challenges for students, and in certain cases, entire societies. Many school systems lack the capacity to help students attain a quality education, and prevailing beliefs have not led to the necessary policy investments to address these issues.
Teach For All supports a network of partner organizations that are growing leaders within their countries to ensure all children have access to an excellent education. These network organizations are enlisting outstanding university graduates to commit two years to teach in areas of educational need; providing significant training and ongoing support to enable these teaching participants to succeed with students; and fostering a community of alumni who become leaders in the classroom and education, to effect the fundamental changes necessary to ensure educational opportunity for all.
In fiscal year 2012 alone, the Teach For All network will collectively field more than 14,000 teachers who will impact the lives of nearly one million students. Meanwhile, a force of roughly 26,000 alumni are now serving as advocates for educational equity, working from across professional sectors to ensure all children have the educational opportunities they deserve.

Virginia Tech's College of Agriculture and Life Sciences, Virginia State University, Virginia Cooperative Extension, The University of Virginia, and the Virginia Food System Council with all its participating organizations initiated the Virginia Farm to Table initiative in September 2010. The goal of the initiative was to strengthen Virginia's food system and economic future through the development of a comprehensive Virginia Farm to Table Plan that informs and integrates assessment, education, development of programs and infrastructure, policy and funding recommendations to address key issues facing farmers, food entrepreneurs, and communities. The Plan would directly address 1) local regional farm and food markets 2) agricultural economic development, 3) community viability and environmental stewardship, and 4) food access, nutrition and health.Underlying assumptions and key tenets for the development of the Virginia Farm to Table Plan was that all Virginians should continued to be educated about the social, environmental and economic importance of the local food system and that quality food should be affordable and accessible to everyone in Virginia regardless of their economic means.

As customer demands grow more exacting, businesses need to cater to their needs quickly. The continuous increase in customers and road traffic can hamper the smooth delivery of products and services.
Route planning apps like Roadwarrior enable businesses to take advantage of their software and eliminate their worries about slow and hassle deliveries. Smart route optimization apps can take the weight off your shoulder by giving you efficient solutions guaranteed to benefit your employees and customers.
Here are some reasons why you should invest in a route planning app for your business:
1.Decreases distance and fuel expenses
These apps can automatically and quickly calculate the routes that your delivery vehicles will take to decrease the distance that needs to be driven. Doing this will also lessen the fuel costs. Make sure to utilize a good route planning app that can assure you of this benefit.
In addition to that, your vehicles will have reduced carbon emissions since they use less fuel than others. The shorter the travel distance, the lower the fuel usage, and the lesser they will contribute to emitting carbon. Using route planning apps is also another way to be eco-friendly.
2.Saves travel time
Since the app can calculate the distances that the vehicle will travel, your employees can save time planning which routes they will take. This way, you're also protecting your employees, especially delivery drivers, from getting lost and overfatigue.
Most software has algorithms that compare different travel times depending on the mode of transport too. Instead of relying on your employee's stock knowledge about routes and stressing them about planning their delivery routes, you can just leave the job to route planning apps. With this, you can also expect more deliveries completed within the day.
3.Ensures customer and employee satisfaction
Route planning apps can give you estimates of how long you will travel. This can give your customers a heads up on which day or what time their orders will come so they can coordinate with you whenever they are not available to receive them.
For employees, you will be able to distribute the workload among the drivers appropriately. This will eliminate inequality in travel times and distances that might spur some problems between the employees and you. The planning apps can solve a lot of hassles related to the delivery of products or services.
4.It helps create stronger delivery strategies.
Route optimization software allows you to do simulations to help make better decisions regarding delivering your products or services. It is advantageous to operational planning and your overall delivery system by calculating the travel time and distance of various vehicles to determine the most efficient option and compare the best delivery times.
Route planners have prevailed due to GPS and the Internet. As a business, you must take advantage of these innovations to upgrade your company's services. Not only will these apps give your employees less hassle, but they can also ensure further customer satisfaction. The faster you can provide services and products to them, the more they will like and trust you.


Asphalt Intermediate Course refers to an aggregate, sand, and asphalt cement mixture used as the intermediate, leveling, or scratch course placed in a lift between the asphalt/stone base and the surface course. Intermediate course is most commonly used in a roadway application, but is also used in driveways, parking lots, and sidewalks.
Asphalt intermediate course mixture typically includes smaller aggregate sizes than Base Courses of asphalt, but larger than surface courses. The most common aggregate composition for asphalt surface course meets the following gradations for amount of crushed limestone material passing through different size sieves:
100% passing 3/8″ sieve
90-100% passing 4.75mm sieve
65-100% passing 2.36mm sieve
40-85% passing 1.18mm sieve
20-60% passing 600micrometer sieve
7-40% passing 300micrometer sieve
0-20% passing 150micrometer sieve
0-10% passing 75 micrometer sieve.
Intermediate Course on top of Base Course
The equipment required when placing Asphalt Intermediate Course will be an asphalt paving machine (or road widener paving machine for widening or trench repair) and 1-3 tandem rollers. The crew required will be 6-7 workers composed of the following: 3 operators for paver (one on top and 2 down low), 2 operators for rollers, and 1-2 laborers for hand raking and finish work.
Asphalt Intermediate Course can be done without a paving machine for smaller areas such as drives or small parking lots, but the production will reduce dramatically as the material will require hand or small equipment placement. Hand placement should be minimized (vs paver placement) if possible as it can lead to a rougher surface texture, segregation of the aggregate, and lessened compaction density. For wide open mainline roads with minimal traffic, peak productivity can be achieved. For widened sections, drives, and parking lots with twists, islands, turns, bumpouts, intersections, etc, productivity can be dramatically reduced as these areas require considerable handwork and starting/stopping/slowing of the paver.
A critical part of the road section assembly, asphalt intermediate course serves as the leveling, binding, or 'scratch' course prior to the placement of the surface course lift and requires a level, true longitudinal placement and often has a transverse cross slope from the crown of the road to the shoulder. For these reasons it will require a fair degree of horizontal, vertical, and aesthetic accuracy in preparation for the surface course. Bumps, low spots, and high spots can be somewhat compensated for in the surface course but the fewer imperfections there are in the intermediate, the easier the surface course can be placed with accuracy. Most engineers and localities will permit minimal amount of (commonly 0-35% of dry weight) RAP (Recycled Asphalt Product) in the mixture. RAP is considered not to perform and bind the mixture together as efficiently as new fresh asphalt binder.

General Productivity Growth in a Theory of Quits and Layoffs
An efficient matching model of quits and layoffs is developed to account for several empirical regularities. Differences between quits and layoffs over the life and business cycles and across demographic groups are generated by differential rates of general productivity growth. The standard approach to quits and layoffs, based on wage rigidity, is shown to be incapable of accounting for many of the empirical regularities. Although a formal test rejects a structural prediction of the efficient turnover model, the specification does well in predicting both the level of, and time-series variation in, the fraction of separations labeled quits.
