Newton, Leibniz, and the Invention of Calculus - Essay Example The theorem was the start of the NewtonÃ¢â¬â¢s mathematical innovation (Dunham 6). In 1666, Newton made his first contribution to calculus through the introduction of fluxions. In the late 1665 before his first publication, Newton had made studies on the tangent problems by combining velocity components of the moving points in a proper coordinate system. This was vital for the introduction of fluxions which is a key component in geometric applications (Edwards 191). Newton was capable of exploiting the concepts of antidifferentiation and differentiation by the substitution methods. This is the equivalent of what is called integration and chain rule by substitution. This is essential in the building of calculus of fluxions (Edwards 196). Newton applied the method of successive approximations in his De Analysi to the reversion of series. Newton proceeds further to use the technique of reversion of series in the discovery of sine and cosine series (Edwards

Adams equity theory 3.4. 4 Equity Theory Adams s (1965) equity theory is another form of motivation. In this model, like in expectancy theory, people are viewed as having thoughts, feeling, and opinions that affect their work. He also proposes that the social comparison process begins with the individuals assessment of what he or she need to puts into the job relative to what is received from it. That is, the person develops a cognitive ratio composed of the inputs to the job and the return (output) from it. Inputs Typically, inputs are consider as an effort, loyalty, hard work, commitment, skill, ability, adaptability, flexibility, tolerance, determination, heart and soul, enthusiasm, trust in our boss and superiors, support of colleagues and subordinates, personal sacrifice, etc. Outputs The outputs typically are define as financial rewards, for example pay salary, expenses, perks, benefits, pension arrangements, bonus and commission plus intangibles recognition, reputation, praise and thanks, interest, responsibility, stimulus, travel, training, development, sense of achievement and advancement, promotion, etc. According to Adams (1965), people who feel that there is fairness between inputs and outputs. T he output/input(O/I) ratio denotes the proportion of job inputs (I) to job outputs (O), and it expresses to the extent to which of the exchange is felt to be appropriate. People feel it will be fair if the exchange of the output is seen to be as equal as the input. When outputs are greater than inputs, people know they are overpaid, and conversely, when outputs are less than inputs, people feel underpaid. In a second phase of the process, people engage in social comparison. They begin by assessing the O/I ratios of others at work. Then, the person compares their self-ratio with the ratios of other significant persons. 184.108.40.206 Discussions on Equity Theory Equity theory has been used as a guide for paying and motivation, particularly in terms of changes in the quality and quantity of performance. Reviewers of the research have reported that the predicted effects of underpayment on performance are well supported (Campbell and Pritchard, 1976; Goodman and Friedman, 1971). Decreased production among underpaid hourly subjects has been observed as predicted (Pritchard, Dunnette, and Jorgenson, 1972). Increased production coupled with decreased work quality among underpaid piece rate subjects also has been observed (Lawler and OGara, 1967). 3.4.6 Goal-setting Therory Like equity and expectancy theories, goal-setting theory is consider as a process theory. Locke (1968) initiated the original work on this theory. The theory identifies the contents of the motivational structure, but the greater emphasis is on the process of motivation. Goals are the central feature of the motivational structure. His studies resulted in three main conclusions: More difficult goals result in higher levels of performance than easy goals. This is the first conclusion. The outcomes of a series of experiments showed that Ã¢â¬Å"although subjects with very hard goals reached their goals far less often than subjects with very easy goals, the former consistently performed at a higher level than the latterÃ¢â¬ (Lock, 1968). Specific goals produce higher levels of performance than general goals (e.g. Ã¢â¬ËDo your best!) Locke suggests that one of the features of specific, hard goals is that they prolong effort during the latter portions of long work sessions (Locke, 1968). Locke also reported on a study by Meyer, Kay and French (1965) into goal-setting during appraisal interviews. They found that the tasks that were translated into specific goals resulted in greater performance outcomes than tasks that were not. Behavioural intentions influence the choices people make. This is the final conclusion. Behavioural intention was defined as Ã¢â¬Å"the intention to make a certain task choice or to respond in a certain wayÃ¢â¬ (Locke, 1968). In other words, Locke concluded that the level of difficulty of a chosen goal depended on what the person undertaking the task was aiming to achieve. 220.127.116.11 Discussions on Goal-setting Theory Goal-setting theory is useful to many managers because much of people management is specifically about performance against goals. It is also a theory that human resource professionals are likely to be familiar with because it is often focus on objectives. Although the Goal-setting theory specifically states that goals have to be considered valid for them to be motivating, the theory does not cover the issue of goal commitment according to Hollyforde and Whiddett (2002). Peoples commitment to a goal is an obviously key to anticipating their motivation to succeed at it. Carroll and Tosi (1973) reported that the self-esteem seems to be an important factor here. For example, managers with high self-esteem reported they were more persistent in meeting their goals than those managers with low self-esteem. In general, Goal-setting theory is a theory that has great relevance for managers. The three conclusions of the theory that suggest that the most motivating goals are not only specific but also challenging must ring true for many managers.

Racial profiling has become a severe obstacle in the U.S. today though most Americans know very little of this vital issue. Every day, people are being pulled over, harassed, and even killed for being of a certain race. There are new laws that politicians are trying to pass that promote racial discrimination. Racial profiling is immoral and does not increase public safety. Incarceration rates are a definite proof that racial discrimination occurs.

The latest tooth-shaped guard plate is adopted to increase effective length of jaw plate and improve output. [pic] Working Principle: The motor transmits power through belt, drives the moving jaw to do periodic motion towards the fixed jaw by the eccentric shaft.The angle between toggle plate and moving jaw plate increases when moving jaw moves. So the moving jaw moves towards the fixed jaw. The stuff will be crushed in this process. The angle between toggle plate and moving jaw decreases when moving jaw moves down, the moving jaw moves leaves fixed jaw b y pulling rod and spring, the final crushed stuff will be discharged from the outlet.

Legalization of cannabis has been a very controversial issue in the United States for a long time; even more so after several states have already passed the legislation lifting the ban. Should all marijuana be legal? Is it dangerous? What are the possible implications of this? It is one of these topics that people just cannot help but have diametrically opposite viewpoints on. For decades marijuana was considered to be a dangerous drug, leading to criminal behavior and personal degradation. However, by now most of these beliefs have been discredited Ã¢â¬â there is little to no proof that cannabis in and of itself has any adverse effects. Some studies even show that it is far less dangerous than many completely legal prescription drugs Ã¢â¬â both for its users and those around them. In addition to that, there is corroborative proof of marijuanaÃ¢â¬â¢s positive medical effects. Cannabis is beneficial for epilepsy patients, it eases nausea caused by chemotherapy and shows good results when used by people suffering from AIDS, glaucoma, multiple sclerosis and a number of other conditions. In other words, legalization of cannabis can greatly improve the quality of life of all these people, while proof of its lasting or even temporary adverse effects remains more than scarce. But even if we take medical use of cannabis aside, letÃ¢â¬â¢s ask ourselves a simple question: the war on drugs has been raging for decades, billions of government spending have been poured down this sinkhole, hundreds of thousands of people were convicted on drug charges, tens of thousands are getting killed in drug wars in Mexico and South America Ã¢â¬â yet the results are less than nil. Drug trade is running rampant, tens of thousands die in drug-related shootings and gang warfare, prisons are overfilled with people charged with possession or selling drugs (and a large percentage of them has been arrested over finding a tiny amount of marijuana on them), time in prison makes it difficult for these people to find proper jobs later on, again pushing them towards criminal activities, thousands of addicts die due to overdose. It seems that Prohibition era should have taught us that criminalizing an activity doesnÃ¢â¬â¢t make it disappear Ã¢â¬â it simply procreates organized crime. Most narcotic drugs are relatively simple and cheap in production Ã¢â¬â their high prices are caused by their illegal status and dangers accompanying producing and selling them. The war on drugs is exactly what causes drug mafia to exist in the first place Ã¢â¬â and in the long run, losses from the war on drugs by far exceed any positive effects it may have. That is the prime reason to legalize marijuana and, ideally, drugs in general. It is impossible to eliminate them. It is impossible to protect people from themselves. If somebody wants to follow his or her self-destructive tendencies, it is not the stateÃ¢â¬â¢s job to be his or her nanny. If drugs are legalized and cheap, a drug addict is very unlikely to harm anybody but himself Ã¢â¬â and we should take into account a greatly diminished risk of overdose, infection and other dangers accompanying illicit drugs.

The Issue of Affirmative Action A major controversy encompassing the country is the issue of affirmative action. Many believe that the abolition, or at least restructure, of affirmative action in the United States will benefit the nation for many logical reasons. Originally, affirmative action began as an attempt to eliminate discrimination and provide a source of opportunity; affirmative action did not begin as an attempt to support just minorities and women. In addition, affirmative action naturally creates resentment when the less qualified are preferred instead of the people actually deserve the admission or job. Another reason that has existed since the abolition of slavery is the myth that women and ?minorities? cannot competeÃ¢â¬ ¦show more contentÃ¢â¬ ¦There are three applicants for the job offering. One applicant is a white male age 35 who has six years of on the job experience. The other three are an Asian female, black male, and white female. Two of these minority applicants have no practical experie nce and the other only a few years. In order for the company to meet the quota, the company must automatically reject the white male and only look at the other three applicants. The company now is no longer looking for good experienced employees; instead, they are trying to appear fair. This so called ?equal opportunity? is not what it says. This means that they provide ?equal opportunity for minorities.? They are now discriminating against majorities, which goes against the original initiative for civil rights. Affirmative action is actually dividing the country into two different racial categories: all minorities against the majority. This causes severe resentment towards those minorities who are less qualified yet are preferred because they feel sympathy or pity towards them. When trying to apply and qualify for scholarships an applicant will find that the majority of the scholarships are for minority or specific race only descendants. This disqualifies everyone who needs the sch olarship, but was not born under a certain type of ancestry.
