Faculty, Quizzes, and a New Learning Management System Research Paper

Faculty, Quizzes, and a New Learning Management System - Research Paper Example One of the ways in which a researcher performing forecasting for any market variable such as stock market volatility can ensure that the forecasting is accurate and authentic is through the use of time series analysis. This is because in time series analysis, researchers make use of existing figures and facts in drawing conclusions (Ziya, Dogan and Kelecioglu, 2010). One interesting phenomenon about time series that make them appropriate for forecasting is the cyclical nature of business. Because of the business cycle that is normally observed in a typical economic environment, there are various cyclical components of time series analysis that makes it possible to forecast based on the assumption that the trends with the behavior of market variables will always remain the same (Williams and Monge, 2000). Indeed in the absence of such cyclical components, forecasting would be virtually impossible because key market variables that could make it possible to make predictions about the market would have to be investigated for each time a time series analysis has to be performed. A typical component of a business cycle is the fact that there are periods of prosperity, which are followed with recession, depression, before recovery (Grebennikov and Shah, 2013). All such cyclical components enhance forecasting. Ziya, E., Dogan, N. and Kelecioglu, H. (2010).

Case Problem - Essay Example In this essay, the aim is to argue that in the case of Isabella vs. Cato, the former can successfully, enforce the latter’s promise. The background of this case is that Cato promised Isabella $40,000 upon enrolment and subsequent graduation from college to which the latter successfully does. Upon demand of the honoring of the promise, Cato cites lack of contract and enforceability. In this case, Cato cannot denounce the contract because Isabella has honored her part. According to US constitution, â€Å"If an oral contract that cannot be fulfilled within one year has been fully performed, the contract is fully enforceable (regardless of how long performance actually took)† (National Paralegal College, p.12) Had Isabella failed to enroll or fail to graduate from the college, Cato would have legal grounds to overlook the contracts. If one party fails to honor their part of bargain there has to be a case (National Paralegal College, p.12). In other words, if Isabella despite failure to graduate still demanded the $40000 promise, Cato would not pay. Conversely, now that she graduated, Cato has to honor the promise. Worth noting is the fact that a contract does not necessarily need to be in a written form to become enforceable. Nevertheless, it is vitally important to understand that in United States, some contracts have to be in form of writing. As for the Cato –Isabella case, this is not one of the cases requiring such

Investigate whether some vocabulary learning strategies are superior Literature review

Investigate whether some vocabulary learning strategies are superior to others - Literature review Example Environmental factors may involve the host culture and available output opportunities. While there are some methods that seem to work more effectively for second language vocabulary acquisition, Many researchers and professionals have recently taken great interest in the strategies for learning second language vocabulary. These include linguists, psychologists, sociologists, and language teachers (Meara 1997). By their studies they examined many different strategies for learning vocabulary: rote memorization with, or without, a language lab, translation exercises, drill and practice, live and digital computer aided conversation, listening to music or stories, with or without the text in hand or on screen, matching and other word games, watching movies and other videos, with or without subtitles, reading books or booklets, with or without looking up unknown words and writing sentences, conversations, scripts and stories, with or without using a dictionary (Cohen, 76, 2001). Crucial to vocabulary, or another, learning is assessment. Even students using self-study need assessment to guide them in what to study. Assessment methods that work without being intrusive or interferin g with learning processes are best (Stahl, Katherine A. DoughertyBravo,Marco A. 2010). Guessing, not mentioned earlier, as a strategy towards vocabulary acquisition in a second language is commonly encouraged (McCarthy, 102, 1990). The first language develops naturally, not as a result of direct instruction, but by trial and error (Ellis, 125, 1997). The child tries a sound and looks for a response. Then the child tries to repeat the sound and looks for the same response. Eventually the child discovers that certain sounds are connected to certain responses, many of which fulfill the needs of the child, some which do little or nothing and some which get undesirable responses. Therefore, second language development should work well following the

Case study - Essay Example The deal was going on well with the company making small losses and gains to balance the losses, an indication that all systems were right. However, in mid April 1994, Artzt, the chairman of P & G, made a shocking revelation that the company had made a whopping $157 million loss after liquidating two interest rate swap contracts (Smith, 68). This was in addition to a $102 million after tax charge against the company’s third quarter profits to cover the losses incurred in the transaction (Malkin, 1994). The scenario was that P $ G had a signed a contract that considerably magnified the interest rates swings in a 3 years swap in which the company paid a floating rate on Libor (Smith, 69). The intention of the company was to make an interest in the event that interest rates fell or remained constant, which could have led the prices of the relevant bonds increasing or remaining constant. As a result, the company could have paid the expected Libor rate while still benefiting from t he income from Bankers Trust for the options. However, the short interest rates rose significantly leading to a decline in the prices of the long term bonds, forcing P & G to buy the derivatives at rates way above the selling value. In other words, P &G found itself paying rates above the selling value due to the sensitivity of the long term bonds to the slightest movement in interest rates. Consequently, P & G had to pay much higher to purchase back the derivatives from Bankers Trust than what the bank had paid for them due to the increase in the value of the options held by the bank as a result of a rise in interest rates (Heffernan, 641). P & G incurred the above losses due to interest rates volatility in the market, which made the company buy its swiped instruments at much higher costs than the bank had paid. The outcome of the transaction was that two P & G employees considered to bear the

Week 3-4 - Assignment Example Quality literacy learning happens when students are offered the opportunities to appreciate recreational and creative aspect of the entire literature and other kinds of texts (Nixon, Comber, with Grant, & Wells, 2010). The curriculum should therefore allow students to fully participate in the society. The program should involve among other forms of support an emphasis on independent reading and independent writing alongside critical literacy to achieve independent learning for diverse learners. This should be crowned by a proper ongoing assessment that involves the following: running records, observation surveys, observation checklists, rubrics, anecdotal records, and marking scales. Using an ‘inquiry stance’ permits teachers to analyze the dynamics and complexities of their classroom communities as well as to design curriculum basing on their knowledge/understanding of students in their circumstances (Nixon, Comber, with Grant, & Wells, 2010). This means, teacher-researchers in schools teaching diverse students bring social circumstance into the foreground; they take into social circumstance to be more than the ‘background’ to the lives of their students’. This approach makes the cultural and linguistic diversity of families a property rather than a deficit. The discussion here follows the work of a teacher who combines critical approach literacy with a property model of cultural diversity (Laura & Carol, 2008). This involves, foregrounding students’ cultural and linguistic resources in the curriculum to generate high quality literature results for diverse learners. The school I teach, it serves a diverse community of students. This includes significant numbers of languages speakers other than English in each classroom. This means that in there are collaborations between teachers to help linguistically and culturally diverse students to develop their literacy in English and other learning

Critically analyse the factors (including Talent Identification and Essay

Critically analyse the factors (including Talent Identification and Development) that have been responsible for sporting excellence and the radical turnaround in team GBs Olympic success - Essay Example There has been a corresponding improvement in number and value of medals received by the team as well over the last 15 years. According to (Green and Oakley 2001a), team GB participates in all games arranging from athletics, cycling, boxing, badminton, diving, golf, hockey among others. There is a good team planning and management in team GB. This is achieved through proper identification, confirmation ad development of talents in members of the various teams. In talent identification, players go through proper screening. This is done by their various team coaches with the aim of identifying the specific talents for each of their team members (Bompa 1985). In order to achieve this, the coaches apply various talent identification methods especially scientific and natural methods. According to Balyi (2002), the use of scientific selection method which is based on talent level and physical attributes reduces the time required for the player to attain high level performance. The purpose of talent identification is to ensure that team members are appropriately placed in the type of race they will perform excellently as in the case of athletes or game position for example in football. For games that require either singles or double for example badminton, the coach will know which player will play excellently in singles. After the talent has been identified, the coach has to confirm it again. This involves extended assessment of the identified talent so as to verify the talent characteristics. It also includes the talent’s trainability, coachability and adaptability to an environment of high performance. This gives the individual a chance to get a deeper understanding of high performance sport. What follows talent confirmation is talent development. In this stage, players are maintained in a specialized environment that will facilitate their progress

The mutation rate Essay Example for Free

The mutation rate Essay One of the greatest challenges for evolutionary biology is explaining the widespread occurrence of sexual reproduction, and the associated process of genetic recombination. Sexual reproduction involves one individual combining half its DNA with half of DNA of another individual, so that the offspring is only half genetic copy of each parent. However, in asexual reproduction, the offspring are genetic copies of the parent. Thus, sexual reproduction poses an evolutionary problem because it seems to be half as efficient a method of reproducing as asexual reproduction. Asexual females can potentially produce twice as many daughters as sexual females, so that the ratio of asexual to sexual females should initially double each generation, resulting in the two-fold cost of sex.? In addition to this 50% cost and the dilution of the individuals genome, sexual reproduction also presents other disadvantages in comparison to asexual reproduction. First and foremost there is the cost of recombination favourable gene combinations that have increased in frequency under the action of natural selection are broken up. Secondly, the process of sexual reproduction requires a significant cellular-mechanical cost as sex requires meiosis, syngamy and karyogamy. A great amount of time is taken up by these three processes alone, and far exceeds the time required for two mitotic divisions. Also, these processes are unnecessarily complicated if reproduction is sole objective. Asexual spores and meiosis-bypassing apomixis appears much more efficient. Thirdly, sexual species can not perpetuate what are often fitness-improving types (eg: triploids, aneuploids). Finally, the actual physical contact between organisms/gametes entails risks separate from those that are maintained by sexual competition. One of the primary costs of initial contact is the risk of disease or parasite transmission. Another significant cost associated with fertilisation is the eminent wastage of gametes, or more appropriately in some cases, a waste of effort transmitting gametes. Given all of these costs, we would expect natural selection to favour asexual reproduction in wild populations, however, it generally does not: sexual reproduction is widespread throughout the animal and plant kingdoms. Sexual reproduction must enjoy some evolutionary advantage, which means that the advantage is not caused by the process itself, but by the changes it causes in progeny genotypes (as a result of recombination), which should drive the evolution of sex. Thus, the problem of explaining sex is to find a compensating advantage of sexual reproduction that is large enough to make up for its cost. Many theoretical models have been developed to show the conditions under which there is a sufficiently large short-term advantage for sex to offset this two-fold cost. The general consensus amongst evolutionary biologists is that there are two relatively convincing, modern day theories. Both of these theories are concerned with a deterministic advantage to sex and recombination through the production of genetically variable offspring. This increases efficiency of selection, and hence accelerates the increase in mean fitness. The first of the two theories is known as the Mutational Deterministic Hypothesis (Kondrashov, 1988), and states that sexual reproduction can enable females to reduce the number of deleterious mutations in their offspring. This idea requires that each deleterious mutation leads to a greater decrease in log fitness than the previous mutation (synergistic epistasis between deleterious mutations). The principle theme is that when this is the case, sexual reproduction increases the variance in the number of mutations that will be carried by the offspring. The subsequent lowered fitness of the individuals carrying above average numbers of such deleterious mutations will lead to an increased number of deleterious mutations being eliminated from the population. If the resultant mutation rate per generation is sufficiently high, then this process can theoretically fully compensate for the two-fold cost of sex. However, the genomic mutation rate (U) is exactly where the problem lies, as the plausibility of such a Ratetheory is dependent upon a relatively high rate of mutation within the genome. A female gains the advantage whatever the deleterious mutation rate, but the relative benefit increases with the mutation rate. But what deleterious mutation rate is needed to outweigh the two-fold cost of sex? Kondrashov suggests that the answer depends essentially on the details of the theoretical model, but a rate of about one new deleterious mutation per individual is probably sufficient. Thus, sex becomes advantageous relative to cloning if U is more than about one. This is the most controversial point in this theory, because deleterious mutation rates have historically been thought to be much lower. Mukai has performed a number of experiments on Drosophila and deduced that a mutation rate of 0. 5 per individual per generation was sufficient. The problem concerning mutation rates is difficult to solve as there is no strong factual evidence that exists to rule out mutation rates as high as are required for sex to prosper. However, Mukais estimate of 0. 5 per individual was a lower bound estimate, and his results are also compatible with a figure greater than one. The second of the two modern day models ignores the effect of deleterious mutations and concentrates on external environmental change. This model suggests that sex accelerates adaptation to a changing environment by creating new gene combinations.
