From the Paper
"Evertson, Emmer, and Worsham (2003) state that the logical place for a teacher to begin his or her classroom management procedures is in arranging the classroom as it occurs prior to the beginning of the school year. Reflective teachers will arrive at the school several days before their contract calls them to so that they can assess the space to plan for the best arrangement, begin to hang posters and other personal effects, and decorate bulletin boards (Eby, Herrel, & Hicks, 2002). They go on to say that the classroom appearance makes a statement to the students and others about how much the teacher cares for the environment in which the class will learn. Whether the room is tidy or neat, colorful or drab, or filled with extra items to make it livelier will set a tone."

Abstract
The purpose of this paper is to discuss forecasting methods that are used in commercial business. Competition for consumers is high and in order for businesses to survive, they all have to consider what products are needed, where and when they are needed as well as in what quantities. It looks at how a successful forecasting strategy requires selecting the appropriate forecasting technique and compares and in particular contrasts forecasting methods as they relate to an organization called United Parcel Service. It looks at how there are three types of forecasting to predict demand: judgment methods, time series analysis and causal methods.

Judgment Methods
Time Series Analysis
Causal Methods
Conclusion
From the Paper
"Judgment methods can be defined as tools that use opinions to develop forecasts without reference to any available historical data. The basis for judgment methods is to utilize decision-makers that have sufficient experience to establish forecasts. This is a low cost method that has rapid development time. However, it is not consistently accurate and subject to bias. The judgment method would not work at the UPS billing site. Most of the forecasting is based on previous numbers and historical data collected as far back as two years ago. Plans for staffing, potential growth, and volume production are weighed in comparison with these same factors in previous years of operation especially during
their consolidation processes. "

Inferential Statistics, 2005.
This paper discusses the field of inferential statistics and its application.

Abstract
This paper explains that psychologists use statistics to make sense of the human behaviors; through observation measurement and statistical inference, researchers are able to take the abstract and make it more understandable. The author points out that, in inferential statistics, researchers use probability to make generalizations about the entire population based on the results from the research sample. The paper relates that statistics can be used to dictate public policy; thereby, it is especially important that mis-measurements do not occur particularly by drawing samples from non-normative or incomplete populations; while seemingly straightforward, statistics require judicious application of ethical behavior. 2 figures. 6 tables.

From the Paper
"Some of the earliest work in statistics was done by Sir William Perry in 1532, when he began to record the number of deaths in London on a weekly basis. Later in the 1600, James Bernoilli, a Swiss mathematician, begin using probability to predict outcomes. In the 1700s, it was Thomas Bayer who gave birth to the concept of inferential statistics. The normal distribution was discovered in 1733 by a Huguenot refugee de Moivre as an approximation to the binomial distribution when the number of trials is too large. Today, not only do scientists but also many professions rely on statistics to understand behavior and ideally make predictions about what circumstances relate to or cause these behaviors."

Abstract
This paper explains that, inevitably, bridges deteriorate over time at different rates: Timely maintenance activities, which are well-planned and carried out with minimal disruption to road users can present substantial savings in terms of both time and money for both bridge owners and road users. The author ponts out that, to tackle the complicated issues regarding bridge management, research activities in the UK as well as other countries in continental Europe concentrate largely on the bridge management process, with attention given to improving the use of limited finances to maximize the returns from the maintenance and repair of the bridge stock as well as reduce additional costs due to traffic delays and lane closures for these activities. The paper includes a critical review of other BMSs used worldwide, development of models to predict bridge condition over time, analysis of the various road user costs and using different optimizing techniques to best allocate finances and optimize bridge performance. 39 tables. 40 figures.

From the Paper
"It is proposed that the transition probabilities to be used are the Bridge Condition Index (BCI), which operates on a linear scale of 0 (worst) to 100 (best). The degree of severity of bridges is linearly distributed over this range (i.e. BCI of 50 to 51 is the same as 90 to 91), except that costs are expected not to have a linear distribution. This is a useful approach as the BCI (average) is interpreted as 'service potential' and is used as a performance indicator.
Using the example for multi span bridges earlier on, the transition probabilities for a three-state Markov chain model with limiting stage value of 3 is proposed. The probabilities are in accordance to the BCI values for the 'good' bridge arranged in order of descending magnitude (i.e. P(1) = 0.9845 and P(2) = 0.9246). For the purposes of comparison, the other two bridges ('medium' and 'bad') are also modelled and the three are plotted together."

Abstract
This paper explains that the Veterans Health Administration uses aggregation, a process for clustering several similar products or services to group veteran types by age, priority level and enrollees type. It also shows how the VHA uses cost models to reflect the projected health care demand of the enrollees by preferred facility and to reflect the projected health care demands of enrollees by their county of residence. The author outlines the methodology used to develop the Veteran Enrollment, Health Care Utilization and Expenditure Projection Demand Models. The paper states that predictive forecasting customer demand models achieve for the VHA (1) an integrated healthcare plan including financial, capital assets and workforce needs to provide data-driven information for budgetary and legislative and regulatory negotiations with OMB, the President, and Congress; (2) a continuous feedback loop for VHA to assess performance and outcomes and (3) needed information for mandated reporting to Congress. Charts.
From the Paper
"The root of most business decisions is the challenge of forecasting customer demand; this function is a difficult task because the demand for goods and services can vary greatly. External factors impact the VA's demand for healthcare. External factors that affect demand for a firm's products or services are beyond management's control. For example, it is impossible to determine how world events will unfold. Those events that impact our economy and the use of our military may have a profound impact on veterans' enrollment in our health care programs as well as expenditure projections."

Cryptography, 2005.
A discussion of the history of cryptography.
2,014 words (approx. 8.1 pages), 5 sources, APA, $ 63.95

Abstract
This paper discusses the importance of cryptography, explaining that it can be divided into two branches, transposition and substitution. The writer explains how knowledge of cryptography has spread and its uses today.
From the Paper
"In transposition, letters in the message is rearranged, generating it into an anagram. Transposition has a weakness in that small words have a small number of ways it can be rearranged, which makes deciphering messages with very few letters easy; deciphering messages with a large number of letters would be nearly impossible since there may be millions of combinations that the message can form. The alternative to transposition is substitution. One of the earliest uses of a substitution cipher is the Caesar Shift Cipher, where messages were encoded by replacing each letter in the alphabet with the letter three places along. A cipher or encryption method is a procedure method for altering a plaintext message into cipher text by changing the letters of the plaintext using a transformation."

Abstract
By using "The Presocratics", edited by Philip Wheelwright, this paper mainly concentrates on Pythagorean definitions of realities. It looks at how there is a correlation between Pythagorean and modern philosophies, primarily connected to mathematical themes. It goes into depth of defining Mandelbrot sets through math and philosophy and how it connects to ancient philosophy.
From the Paper
"There are many ways to define things that we perceive in our daily lives. We define them through science, art, language, and psychology as in many other ways. Most of the philosophies that exist today come from the 'bare bones' of pre-Socratics. They are the basis of different philosophies as well as studies and advances of our time such as astronomy, biology, physics, psychology, mathematics and many more. Pre-Socratics were the first to record their thoughts about the universe. Of how it originated, what made up the things surrounding us, the composition and elements used to make the universe."

Abstract
Data visualization is the use of interactive, sensory representations, typically visual, of abstract data to reinforce cognition. That, in itself, is a method or technique of decision-making. To further break it down, the most popular and widely used tool of data visualization is the pie chart. This paper presents an introduction of the pie chart and it's most common applications. It explains when it should and should not be used and provides examples in color.
From the Paper
"Pie charts work well when the values of the percentages of the whole differ greatly from each other. In other words, you do not want your pie values to be within one or two digits from each other, which would be indistinguishable on the chart to the naked eye. Another moniker for pie charts is: do not use a pie chart when there are more than six parts to the whole. Having too many values for comparison on the chart will distract from the clear simplistic message and instead offer a complex confusing assortment of data."

Teaching Algebra Comprehension, 2005.
This paper discusses the use of graphing calculators to improve algebra comprehension in high school.
1,830 words (approx. 7.3 pages), 9 sources, APA, $ 58.95
»
Click here to show/hide summary
Abstract
This paper explains that any tool, such as a graphing calculator, which can help students gain an improved mastery of the fundamental skills required to complete algebraic problems, must be viewed as educators as a "Good Thing"; but a consistent theme is the need to keep the material relevant in order to maintain student interest. The author points out that, although students should have the experience of entering the program commands themselves, an alternative approach is for the teacher to write the relevant on one calculator and then distribute it to students' calculators by using their linking capabilities. The paper relates that teachers can adapt the material for use with Texas Instruments (TI), Casio, Hewlett-Packard and Sharp graphing calculators.
From the Paper
"The use of graphing calculators in a comprehensive algebra curriculum has been advocated by a number of educators. For example, some currently teach their students how to solve and graph linear equations manually, give them a test on it that is worth 50 points where no calculators are allowed during the test, classwork, or homework. Afterwards, they teach students how to solve the same or similar problems using a calculator. Then they give them another test of the same topic as during which problems are to be solved only by using calculators. During chapter tests and exams, students have the freedom to choose whether to use a calculator or not. "

Sir Isaac Newton, 2005.
This paper discusses the life and works of one of the most instrumental contributors to mathematical and scientific theory in the last few centuries, Sir Isaac Newton.

Abstract
This paper explains that Sir Isaac Newton advanced a whole new system of mathematics, including systems of physics and calculus, which were revolutionary during his time and continued to be
observed long after his death. The author points out that one of Newton's most significant contributions is his basic laws of motion often call Newton's Laws. The paper relates Isaac Newton would never have described himself as a 'scientist' because the word was not coined until more than a century after his death; he was a reclusive Hebrew scholar and Classicist who wrote more about alchemy and theology than the natural world, and his posthumous reputation is riddled with contradictions.

Conclusion
From the Paper
"Newton's laws of motion can generally be described through example and demonstration and represent a continuation of thought and inquiry into questions of physics. For example, many scientists before Newton could think of explanations for the continuation of movement of a given object due to force and velocity, but could not demonstrate it in a scientific way in the same way that Newton could with his laws of
motion. Using force and velocity, Newton made important mathematical relations that showed up in real world examples. For example, if someone was riding on a horse, they were going the same speed as the horse, then their velocity remained constant, but if something changed their velocity, it would differ from the velocity of the horse, and they
may change velocity in direction of proportionate force. Newton also contributed the commonly repeated maxim that each and every force (action) has an equal and opposite force (reaction). This is a very significant contribution because it represents a basic precept of modern physics."

Chinese-Taiwanese Relations, 2005.
This paper uses an algebraic model in conjunction with an extended strategy game to prove that the passage of Chinese Anti-Secession bill was empirically and scientifically sound.

Abstract
This paper explains the dynamic history of the China-Taiwan relationship especially the controversial Chinese Anti-Secession bill, particularly Article 8, which states that, after exhausting all other avenues, China reserves the right to use military force or embargo to bring the situation with Taiwan to a close, conditional on Taiwan actually declaring independence. The author creates a game with nominal payoffs (a, b,c) creating a situation where China, assumed to be a rational actor, would most prefer, for example, say "c" but could risk getting a payoff of "b". The paper relates that, after computing the minimum threshold using expected utility formulas, arriving at a non-numerical solution, a probability value shows that China was rational in its decision to pass the bill since it saw its chances of being reprimanded by the international community as being much lower than is seen by the international community. Graphy. Formula.
From the Paper
"Those supporting Taiwan in this conflict are the US and Japan, and from this US alliance we could see countries like New Zealand and Australia come to Taiwan's aide if the US decides to invoke the conditions of the ANZUS treaty signed in 1951 . Among those supporting China's position are countries like Pakistan , North Korea, and Russia . If the bill was interpreted as a hostile war bill instead of a "fence-mending" bill as China claims it to be, the global community could formally and militarily become involved in the conflict. Setting aside this possible military threat, China must also weigh the economic consequences, with reaction from the global community that could include sanctions."
