Applied Statistics for Finance and Economics Project report Coursework
Applied Statistics for Finance and Economics Project report - Coursework Example Since in this data we are focused on 2002 to 2006 we see that the seasonal and the cyclic component are present. We take a time plot of the returns data of home furnishers to investigate if the data exhibit trend in this case. From the above trend we can see that there is linear trend in the returns of the home furnishers. To eliminate trend to make the returns data stationary, we take the differencing of lag 1 and observe the progress the remains. The time plot of the returns also shows that the return data exhibit trend. Thus from the above analysis of the returns and return squared, the returns can be predicted and has a very high predictive power while the return squared has very low predictive power. Broadly speaking, a time series is said to be stationary if there is no systematic change in the mean (no trend). If there is systematic change in variance and is strictly periodic variations (seasonal and cyclic component) are removed. Most of probability theory of time series analysis is concerned with stationary time series and for this reason time series analysis requires one to change a non-stationary time series to a stationary time series analysis so as to use it. In this study we plot the variables and test their stationary using a particular variation of unit root test- the Augmented Dickey-Fuller test. We then difference the time series of return to make the series stationary. After differencing the return data we can observe that the data is stationary. This can be clearly seen in the time series plot of the differenced data at lag. The plot of differenced data of returns below shows that the data is stationary after differencing it once. The pair trading is a common thing in the trading market. Literature on pair trading, market efficiency and return volatility behavior is plenty for a developed stock market. The study involves pair trading using the

Sex Education in Schools Essay Example | Topics and Well Written Essays - 1000 words
Sex Education in Schools - Essay Example This paper declares thatà sexuality in children is a complex issue that Sigmund Freud has divided into five stages known as sexual development. The five steps include oral phase, the anal stage also known as bowel, and bladder elimination, a phallic stage that is the discovery of genitals, latency stage which the dormant sexual feelings. The final phase is the genital stage that occurs at maturity of sexuality.à He argues that during every stage of sexual growth, children acquire the vital development to become an adaptive adult. Freud theorized explanations for numerous repressed feelings, and desires, yet also assist in developing strong gender roles. During that time, the boys begin to develop intense anxiety, which is similar to girls.From the discussion it is clear thatà sex education in school is vital in that the teenagers will get to know how sexually transmitted diseases are acquired, the issues of contraception, abstinence. If they are not going to learn them in scho ol where better would they learn about it? From media?Or friends?Or do we want them to learn sex education from the responsible adults? When we leave our children in the hands of the media or friend to give them sex education, we may be initiating ourà problems. Some of the friends or media are deceitful.à They can mislead the young children to their advantage. Moreover, some friend may take advantage of the innocence of the child and abuse the roles they are expected to play. If we cannot trust our schools with such matters then, who can be trusted with our children?

Unites States Current Account Deficit Essay Example | Topics and Well Written Essays - 3000 words
Unites States Current Account Deficit - Essay Example Other government funded interests such as education, military and infrastructure will suffer greatly as well. Why these statements are valid along with imparting a general overview of the national debt so as to illuminate the crisis is this paperââ¬â¢s purpose. If Congress does not control its overspending through measures such as passing a balanced budget amendment to the Constitution and adhering to it, the countryââ¬â¢s economic future is in deep peril. The President submits a proposed budget to Congress in early February for the coming fiscal year that runs from October 1 to September 30 (Executive Office, 2002). The Presidentââ¬â¢s budget request to Congress accomplishes two main objectives. First, it relays the Presidentââ¬â¢s opinion of how much should be taken in via taxation and how much should be spent. Second, it prioritizes the Presidentââ¬â¢s present and future federal funding desires. ââ¬Å"The budget typically sketches out fiscal policy and budget priorities not only for the coming year but for the next five years or moreâ⬠(Coven & Kogan, 2006). When Congress receives the Presidentââ¬â¢s budget, it usually conducts hearings to discuss many of the requests before developing a budget resolution. This is the budgetary parameters that Congress will work within when making their determinations regarding taxes and spending. The budget resolution, drafted by both Senate and House Budget Committees includes b oth mandatory and discretionary spending goals (Executive Office, 2002). Following committee approval, the resolution is submitted for a vote and possible amendments by the entire membership of the Senate and House. Afterwards, a joint House-Senate committee is convened to resolve any disparities in the resolution of the two versions passed by each house of congress. The resulting joint report is sent back to

Supply chain operations and concepts Research Paper
Supply chain operations and concepts - Research Paper Example his endeavor, the rise of the computer age has provided some tools that reduce the level of paperwork in the supply chain while it has also blown apart many of the preconceived ideas regarding territory and boundary. Now, not only are companies attempting to compete with regional and national firms, but must also fend off the advances of international organizations while attempting to gain footholds in new countries. This introduces differing sets of criteria for the supply chain manager including the production of products, governmental regulations or specifications and available technology or resources each of which must be addressed before a product can be offered in a new or old market. To help cope with these multiple concurrent concerns, operations managers and scientists have developed a wide range of strategy sets that are capable of addressing each concern independently or a variety of concerns concurrently depending upon the operation of the firm which is further defined by the type of product produced and the methods by which it is created and delivered. Supply chain management encompasses the planning and management of all activities involved in sourcing and procurement, conversion and all logistics management behaviors. It also includes coordination and collaboration with channel partners, which can be suppliers, intermediaries, third-party service providers or customers. In essence, supply chain management integrates supply and demand management within and across companies. Logistics management is the element of supply chain management that plans, implements and controls the efficient forward and reverse flow and storage of goods, services and related information between the point of origin and the point of consumption in order to meet customersââ¬â¢ requirements (College of Business Administration, 2005). Many types of businesses and organizations most likely to employ supply chain managers include communication, consulting, military,

Reactivity of M-C bonds and catalytic formation of heterocycles Essay
Reactivity of M-C bonds and catalytic formation of heterocycles - Essay Example This branch deals with the synthesis, properties and application of heterocyclic compounds and their derivatives. Heterocyclics are largely categorized as unsaturated and saturated heterocyclics, depending on their structures(Pfaltz&Drury, 2004). The saturated heterocyclics have been noticed to behave like their acyclic derivatives. The core focuses of heterocyclic compound studies are the unsaturated derivatives of 5- and 6- membered rings, their applications and their predominance of low-numbered rings. Among the 5- and 6-membered unsaturated heterocyclics are pyridine, thiophene, pyrrole and furan. Similarly studied to a large extent are benzene-fused rings of these 5- and 6- membered unsaturated heterocyclics(Nakamura et al., 1998). These benzene-fused derivatives are quinoline, benzothiophene, indole, andà benzofuran for pyridine, thiophene, pyrrole, and furan respectively. The following are structures of a heterocyclic and a homocyclic compounds namely pyridine, a heterocycli c and cyclo-octasulfur, a homocyclic compound. From the structures of these compounds it is evident that the C-H bond is quite important in their reactions. In fact, it is the activation of this C-H bond that allows for the formation and introduction of other functionality groups/bonds such as M-C or C-C bonds to heterocyclic compounds(Benudhar et al., 2013). Pyridine Cyclo-octasulfur, The core theme in organometallic chemistry is the construction and transformation of metal-carbon bonds. Consequently, most of researches and literatures seem to focus on the traditional M-C bonds formed using the tetravalent carbon bond. However, fewer researchers have concentrated on non-traditional M-C bonds, often referred to as M-C cage bonds, which are found in carborane cages in which the carbon is hypervalent(Nakamura et al., 1998). This paper explores the reactivity of M-C bonds and outlines a plan for the catalytic formation of heterocyclics via the catalytic activation of the M-C bond. Spec ifically, the aim of this paper is the synthesis of some ligands that contain heterocycles or vinyl groups that can undergo C-H activation to form cyclometallated complexes(Benudhar et al., 2013). Further, the paper investigates the reactivity of the cyclometallated complexes with alkynes and alkenes. Thus, the goal is to assess the relative reactivity of different types of M-C bonds. One of the methods used in the catalytic synthesis of heterocycles is the amphibilic metal ligand activation (AMLA). In the AMLA process, the steps in the activation of the C-H bond entail the use of an electrophilic metal in combination with a deprotonation using an intramolecular base, frequently acetate. Chiral ligands are chemical compounds adapted for and largely used in the asymmetric synthesis of heterocyclic compounds. Chiral ligands are pure organic enantiomers that combine with metallic centers through the process of chelation to yield asymmetric catalysts(Nakamura et al., 1998). It is this c atalyst that later engages in the chemical reaction in which the chirality of a ligand is transferred to the product of the reaction. That is, while initially the ligand is chiral, at the end of the reaction, it is the product, which is chiral. In model situations or reactions, one equivalent catalyst

Doping Essay Example | Topics and Well Written Essays - 4000 words
Doping - Essay Example In the modern international sports situations, one of the often debated issues is one that is concerning the use of performance enhancing drugs that are related with serious medical problems and their use is illegal. It is a practice against the international standards of the sports activities and is very much considered as the evil affecting the sports and games in the current sports culture. ââ¬Å"Performance-enhancing drugs pose a significant risk to the health of athletes, especially young athletes. Furthermore, the use of performance-enhancing drugs is detrimental to the reputation of sportsâ⬠¦Ã¢â¬ (Doping. 2005). Winning medals at the cost of any social conduct or the social order is the fashion of the day. It is notable that in the modern world of sports, many a young athlete, discarding the risks involved in the use of these drugs go on using them and the practice of doping among the youth, internationally, is at an alarming rate today. Thus, there arises the great role of doping control which has a set of well articulated objectives and designs. However in the act of doping control, there are many things to be considered. There are various emotive issues raised by the doping control activities upon which there are predictably different views. Any set of doping control rules needs to be built on sound base. Specifically, the rules must make sure the principles of natural justice and the procedures must be such as to produce fair and consistent outcomes. (O'Leary 2001, p. 11). It is remarkable to note that "throughout history, there are examples that athletes have sought a magic potion to give them that extra edge, to help them take a short cut to achieving a good performance or to enable them to compete under circumstances when otherwise it might not have been possible, such as injury or illness. Today's athletes may simply be following previous traditions." (Mottram 2003, p. 29). This extensive use of drugs and other performance-enhancing substances have been one of the chief issues with the international sports today. In the UK, as in other nations, the controlling of their use has been given primary attention in the legal system related to sports. In the modern scenario, the drug control in sports has been considered one of the primary concerns of the legal system. The international sports law is primarily concerned with the control of drugs and doping in sports. There are many international organisations working in this field, most important among the m being the Olympic Movement. "The governing network or structure of international sports law extends beyond the Olympic Movement. Intergovernmental organizations also formulate and enforce international sports law. Such organizations include Unesco, the Commonwealth Federation, bilateral arrangements, and regional organizations such as the European Communities and the Supreme Council for Sports in Africa. Typically, they recognize the authority of the Olympic Movement but expand its rules and develop new institutions." (International Sports Law: a Replay of Characteristics and Trends. James A. R. Nafziger - author. Journal Title: American Journal of International Law. Volume: 86. Issue: 3. Publication Year: 1992. Page Number: 493.) Apart from these, the involvement of various nations in the activity of doping control is also remarkable. There are international agencies for their support. The International Convention against Doping in Sport signals governmental support for the World Anti-Doping Code which has various sporting organisations as its signatories. (International Convention against Doping in Sport. 2005). All the international sports nations give utmost priority to these and there have been many organisations all through the sports activity which confirms that the sports arena is without the evils of such practices. The system in the UK to control the doping has been particularly acclaimed. In Britain, all the registered competitors need to be tested for drug abuse. (Drugs, Sport and Doping Control. P. 1).
The CIA Research Paper Example | Topics and Well Written Essays - 1750 words
The CIA - Research Paper Example The agency was established in the year 1947 through an act accented to by the then President. The National Security Act was signed by President Truman. Apart from creating the agency, this act also established the office of the Director of Central Intelligence (DCI) who was supposed to be the Presidentââ¬â¢s chief advisor on matters of national security as he was also the head of the United States intelligence community. The DCI was also supposed to head the Central Intelligence Agency. However, in the year 2004, the National Security Act was amended through the Intelligence Reform and Terrorism Prevention Act. This amendment created the office of Director of National Intelligence to take up a number of roles previously carried out by the DCI. It also ensured that the Central Intelligence Agency was under a separate Director. Such agencies as the CIA are employed in performing intelligence gathering services and not the US military as these can easily lead to the declaration of wars. During World War II, the Office of Strategic Services (OSS) was created with the purpose of coordinating espionage activities against the Axis Powers. The CIA was thus created as a successor of this office. Basically, the CIA is charged with the responsibility of collecting information about corporations, foreign governments and individuals in addition to advising policymakers. The agency is headquartered in McLean, Virginia. In some quarters, the CIA is referred to as Other Government Agencies (OGA), The Agency, Langley and The Company. In trying to accomplish its mission, the CIA requires the deployment of high leverage technology, carrying out of research and development for purposes of intelligence. To ensure that the intelligence consumer acquires the best possible intelligence, the CIA engages closely with other agencies and organizations within the Intelligence Community and also carries out independent analyses of topics that are of concern2. The agency
