Introduction for a Chemistry Essay Example for Free

Introduction for a Chemistry Essay The average University student has many tasks to accomplish and much studying to do while combating the onslaught of sleep. Students at the University of the West Indies Mona are no different and recommended amongst themselves a highly rated and popular health supplement â€Å"Yeast-Vite† [8]. Yeast-Vite is a health supplement pill which helps people fight fatigue and improve alertness. The active ingredients in Yeast-Vite are caffeine, vitamin B1, vitamin B2, vitamin B3. The other ingredients are: dried yeast, lactose, powdered cloves, colouring E124, E104, E132, colloidal anhydrous silica, maize starch, and microcrystalline cellulose. [1] Yeast-Vite is a good energy supplier when taken according to the directions. The Manufacturer recommends taking 12 pills in a day [1] to eliminate fatigue and improve concentration. The â€Å"alert† effect can be attributed to Caffeine, a major compound that has been proven to stimulate the central nervous system, heart, muscles, and blood pressure control centres [2]. Each pill contains 50mg of Caffeine according to the label created by the manufacturer. The following structure represents that of caffeine. Though effective, research has shown that the intake of more than 300mg of Caffeine on a daily basis is harmful to the body. Symptoms such as caffeinism, insomnia, irritability, palpitations, Nervous symptoms, upset stomach etc. are experienced and consuming more than 500mg may cause death.[3] Theoretically, the recommended dosage of Yeast-Vite tablets daily can create such harm, since the suggested daily dosage of up to 12 tablets[1] adds up to 600mg –if caffeine content of 50mg per tablet holds true. A problem exists. The recommended daily dosage of Yeast-Vite contained too much caffeine for the human body. It was hypothesized that the caffeine concentration in Yeast-Vite pills could cause negative health effects and that the manufacturer’s idea of the caffeine content may be inaccurate. Three analytical chemistry students decided to test the hypothesis, and over a four week period, conducted the determination of the caffeine content of Yeast-Vite pills using High Performance Liquid Chromatography. The researchers expected the actual caffeine content of pills to be 10mg more/less than 50mg of caffeine and also that Vitamins B1, B2 and B3 could cause significant interference. The analysis was conducted entirely as a group by dissolving pills in water, preparing calibration standards, and determining the concentration of caffeine in the pills via external calibration and standard addition (single spike). High performance liquid chromatography was chosen as the analytical method because caffeine did not fit the criteria for analysis by Gas Chromatography and Atomic Absorption Spectroscopy i.e. caffeine’s volatility was negligible and it had no metal ions.

Discrimination Essay Effects of Discrimination

Discrimination Essay Effects of Discrimination As far as historical records show, no society or nation has been immune to discrimination, either as victim or victimizer. Contemporary forms of discrimination date back to when European colonizers penetrated and transformed previously isolated societies and peoples. The more extreme forms of discriminatory practices include genocide, slavery, legislated discrimination (such as Apartheid), discriminatory immigration laws, and disenfranchisement. Less extreme forms of prejudice and discrimination, but nevertheless pervasive and oppressive, include social exclusion at the institutional level (such as in schools and hospitals), and the more subtle forms practised by the media. Some groups appear to suffer from more persistent forms of discrimination, such as Jews (as in anti-Semitism) and the Roma (a.k.a. Gypsies), regardless of time and place. The keywords that need to be looked into before delving the topic in question are discrimination and disturbing. According to the Oxford Dictionary, disturbing means causing distress or worry or anxiety, upsetting, an unpleasant mental state by such effects as irritation, unfairness and distraction. Discrimination, brings the meaning unfair treatment of a person or group on the basis of prejudice and partiality. It can lead to emotions such as frustration and anger. In humans, it is a mild or serious form of suffering, often with anger about this, in particular, if applicable, anger at the person or persons who caused it. This essay examines the cause and effects of discrimination in its various forms, on an individual, society or nation. Our world has always been faced with the problem of discrimination. It is one of the most discussed topics nowadays and throughout history. In all countries there is most likely at least one type of discrimination that affects different groups of people. The definition of discrimination is the denial of opportunity or equal rights for a specific group of people that may be differentiated by things such as their religion, color of skin, or gender. Discrimination can be confused with other terms such as prejudice and stereotype. The world we live in has been struggling with this sensitive subject for as long as we have recorded. Stereotypes are images held in our minds in regards to certain racial or cultural groups, without consideration of whether the images held are true or false. Stemming from stereotypes is prejudice. The prejudicial attitude occurs when we prejudge a person, good or bad, on the basis that the stereotypes associated with the person or group being prejudged are tru e. Discrimination is the combination of the terms mentioned above, but involves actually acting out with unfair treatment, directing the action towards the person or group. Prejudice and discrimination do not just occur racially, but it is found among gender, religion, culture, and geographical background. Remember that prejudice is a result of attitude and discrimination is a result of action. Many people believe discrimination has made big steps forward, but has it really? If it has, why do people still get turned down, receive hate mail, or get ridiculed simply because they differ from each other. I guess these are questions we must ask ourselves. I guess you could also ask yourself if you have ever called anybody a name, looked at them different or judged them when you did not even know them or understand them. You may be thinking That is not discrimination, but, in fact, it is. CAUSE AND EFFECTS OF DISCRIMINATION There are many forms of discrimination, besides the more familiar forms like race and gender, based on ethnicity, religion, sexual orientation, age , disability or handicap, and sexual harassment. The mentioned characterization refers to a situation of the direct discrimination, in which a person is treated adversely directly on the basis of a prohibited ground. Indirect discrimination, refers to a situation in which an apparently neutral provision or practice is discriminatory in its effects. Besides direct and indirect discrimination, we may use the term institutional discrimination. Institutional discrimination refers to the practices or procedures in a company or an institution, or even the society as a whole, which are structured in a way that tends to produce discriminatory effects, for example in the Apartheid regime in South Africa. As to the root cause, discrimination appears to be no clear acceptance of any theory of causation but that discrimination often causes a chain reaction of disadvantages. For instance, it should be noted that there is a connection also between discrimination and social distance, given that it is usually psychologically easier to discriminate against people that one is not familiar with. Although there is no wide agreement as to the cause of discrimination, there is a consensus that they constitute a learned behavior. The internalization of discrimination starts with parents and, later, teachersthe groups primary in the formation of attitudes within children. The media and social institutions solidify discriminatory attitudes, giving them social legitimacy, since discrimination is learned. At best, one can reduce discrimination. Society looks most often to education and legislation to alleviate discriminationfor reasons still not clearly known, intergroup contact alone is not enough to reduce discrimination. On one hand, multicultural education, whether direct or indirect, constitute the mainstay of educational efforts to eliminate discrimination. On the other hand, the emphasis on civil rights, enlightened immigration policies, and mandates for quota hiring are the cornerstone of legal approaches to alleviating the effects of discrimination. The most overlooked area in resolving the problems of discrimination lies in the web of close relationships where genuine feelings of love can be fostered and strengthened. Discrimination produces immense effects in the psychological, social, political, and economic domains. Whether intended or not, the effects are compounded by the loss of self-worth, a sense of alienation from the wider society, political disempowerment, and economic inequalities. Prejudice and ethnic hostilities constitute a major danger to peace both within a nation and among nations. As a consequence, the emergence of a new global moral order increasingly provides a leverage point to counter the effects of prejudice and discrimination. While many agree that the various international instruments to protect people against prejudice and discrimination are still not universally followed or even implemented, it is clear that a new international consciousness is indeed emerging and is, in fact, intensifying. The effects of discrimination in society are reflecting on race, religion, and disable discrimination. One of the main reasons cause violence is race discrimination. It is easy to find evidence from Hollywood movies. The black people always fight with white people because they were discriminated. Now in Australia, the aborigines are discriminated. Many people do not understand their culture, so the Australian looks down on these people. In addition religion discrimination can endanger the world peace. Different religion has different god and the numbers of believers are huge. Once the conflict between different religions break out, which can easily cause a world war. Discrimination is about exclusion an d subordination and it effectively conveys an explicit message of differentness and inferiority of the victim Humiliation. Studies carried out in the field of racial discrimination provide also direct proof of this humiliating nature of discrimination, as it has been found that experiences of racism and racial discrimination have a direct bearing to the psychological well-being of persons w ho have suffered ethnic discrimination: such experiences were found to increase symptoms related to anxiety and depression. There are no reasons to believe that the same would not apply with regard to the other grounds as well. Victims of discrimination cope with these experiences in a variety of ways. As a response to experiences of discrimination, victims often consciously or unconsciously develop a strategy of survival. Some engage themselves in what might be called denial of discrimination. They may explain the incident in terms other than discrimination, or even believe that the discriminatory framework was legitimate, blaming themselves for what happened. One very typical strategy of survival is avoidance, by way of which an individual seeks voluntarily to avoid situations in which the probability to end up discriminated against is particularly high, by way of self-imposed restrictions. From the point of view of the society this is not however a desirable strategy, as lessened social contacts ruin the possibility of integrating vulnerable groups to the general society. Discrimination leads to disunity which results in the dissolving of society, through strife and war. World peace will elude our gras p while discrimination continue to bedevil the collective life of humanity CONCLUSION Discrimination runs against the most fundamental values of a modern society. In fact, it is a threat to democracy, which is predicated on the idea of a society in which arbitrary hierarchies and preferences based on, for example gender, ethnic origin, and wealth have been eliminated with a view to achieving equality. Democracy recognizes worth and equal rights of all whereby, equality prohibits discrimination which is also the cornerstone of human rights. Discrimination not only forms a menace to the society, but also to the individual who is subjected to such an adverse treatment as it is a direct denial of the equal worth of the victim. It is a violation of a persons identity. The consequences of discrimination match the severity of the offence, a causal link to alienation, exclusion, radicalization and decreasing psychological well-being. Therefore, discrimination is wrong because it is selfish. Discrimination throughout the world today occurs to many extremes. From one extreme to another, it is in any way wrong. Discrimination is happening all over the world, today for many reasons. One being because parents have taught their children to believe and think the way they do. The only thing we can do about it is to raise our children to not discriminate against others. It could lead to more tension and fighting within people and groups. To sum up, the discrimination can cause many problems. The government should constitute laws to avoid it, and society should also set up some organizations, programs or communities to help build a better plateau rid of discrimination.

soliloquies in the merchant of venice :: Free Merchant of Venice Essays

  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"The Merchant of Venice† is a play that relies on soliloquies to advance the plot, create mood and atmosphere, and to develop character among all the actors.   Ã‚  Ã‚  Ã‚  Ã‚  I am here to prove how this happens in two different soliloquies and show you why Shakespeare put them into the play.   Ã‚  Ã‚  Ã‚  Ã‚  My first soliloquy is from Lancelot Gobbo and it is taken from Act 2 Scene 2.I know that Lancelot is a secondary character, but this speech is really important in the outcome of this scene. He is talking about if he should run away from his master, who just happens to be Shylock. This soliloquy has all the makings of what a soliloquy should do.   Ã‚  Ã‚  Ã‚  Ã‚  It creates the mood that Lancelot (Shylock’s jester) is having alot of troubles trying to decide whether to run away or not. It must have alot to do with how Shylock treats him since he calls Shylock â€Å"a kind of devil† and also says that he can’t handle being â€Å"ruled by the fiend.† He must have really been mistreated under Shylock’s care to go as so far as to run away from him. It creates the mood of sadness and hatred in Lancelot, and a dark evil kind of feeling towards Shylock for what he has done.   Ã‚  Ã‚  Ã‚  Ã‚  It develops the character that Lancelot is a hard working man who is just trying to make a decent living but cannot because of the way he is being treated by Shylock. It also shows us that Shylock may be the character that, in the play, is the character to fear. We don’t know the details of what Shylock did to Lancelot so we have to cut him a little slack. But whatever he did to Lancelot has made him very angry and disgruntled.   Ã‚  Ã‚  Ã‚  Ã‚  And it develops the plot by starting off the main reason for this scene which is for Bassiano to get into the picture and for Gratiano to ask him if he can go to Belmont with him. It gets to this stage by Old Gobbo asking Bassiano if he will employ Lancelot, which he agrees to. It also tells of what to expect from Shylock in the later scenes which is unheartedness and ruthlessness.   Ã‚  Ã‚  Ã‚  Ã‚  My second soliloquy is taken from act 3 scene 2. In this scene Portia asks Bassiano to wait a few days to before he makes his choice on which casket to open in order to see if he will be able to marry Portia, but Bassiano refuses and wants to make his choice immediately. He makes his choice and

Cohens Acting Power :: Essays Papers

Cohens Acting Power The main point of Cohen’s Acting Power is balance. In the book, he brings up concepts, sites examples, sometimes brings exercises to help his point, and restates the point. I personally did not like this book, but I did not hate it. At times, it was confusing, very vague, and hard to understand, but at the same time, this indicates the difficulty of the concepts Cohen is conveying. Many of the ideas and concepts in this book are hard to explain by word, much less typed word, so I gave this book more patience than I normally would with a regular textbook. One aspect that I did really like, was how Cohen brought everything back into focus in the last chapter on Alignment. Alignment is how an actor chooses to handle the four attributes to a performance; situation, character, style and performance. Proper alignment of how an actor handles the situation, the behavior and style of the character, and performing in front of an audience usually brings a good performance. It isn’t enough to get three out of four, because each attribute is important. Throughout the book, I found things that I had trouble grasping, and many times, they didn’t seem like they’re related to each other, but at the end of the book, the chapter on alignment, it all made much more sense to me. The book is structured like how alignment should be constructed. In the first two chapters it went through stuff about situations, then character, then style and performance. At the end, the book tied how everything relates. I think that the most important thing I got from this book, is the relacom concepts. I found if I translate almost every line of a scene, the intentions reveal themselves, and the delivery of line, is much more convincing. Another concept that I have always wanted to express, but couldn’t find the words, is the idea of ethno-centricity. I can’t remember which chapter it was in, but it explained that everyone thinks their own world is the center, and to properly build a character, sometimes you must lose this ethno-centiricity.

The disvantage and advantage of globalization

Globalization describes the process by which regional economies, societies, and cultures have become integrated through a global network of communication, transportation, and trade. † (Globalization, 2010). Nowadays, small business has to compete against multinational companies face to face as globalization becomes an irreversible momentum. In some case, small business have no need to against the large companies because they focus on different scale until the small companies grow up.However, I agree that small business in IT industries cannot compete against multinational companies when small companies become threats to the lager ones. In this essay, I will explain why small business still exist today and compare their advantages to multinational companies in the sector of financial strengths and productivity advantages. Small business still exists now because they have unique features, especially they focus on the lower market. It is no need for them to compete against the mul tinational companies Sometimes. Hey sever the specific communities. Such as they are willing to run their small business in some small illegal and remote area where multinational firms do not pay attention to. Enclave, K. (2002) argued that small business have to overcome these rules: â€Å"†¦ Information technology (IT) powerless crowd out product development Initiatives†¦ † It Is clearly that overcoming these sales abstract is difficult but not impossible. Small business has its own advantages because it can use convenient and easy solutions to common business problems.However, low price is the most popular strategy for small business to make profits and attract customers' attention. Small business spends less none on advanced Invention. Comparing Dell Company mentioned by Enclave (2002) that if they want to enlarge their popularity they have prepackaged solutions to meet unique buyer's need. They set up specific system to solve these problems to keep In touch wit h their customers. As a result, they have to Invest more money to the stuff. In order to maintain their cost, they have to raise the selling price. That Is the major reason why small business can exist at present.But after small companies changes into large ones, multinational firms consider those companies as a threat, in order to hold their markets share, which will acquire or knock down small business before they growth. Multinational corporations have financial strength support them to enlarge their market share. As a result, it is relatively easy for them to meet the customers' need and enhance their reputation. Large companies are willing to spend money on observations about what people really need and want to buy. They invest amount of money In advertising their products.For example, IBM personal computer business was acquired by Chinese famous personal computer brand Leno, and hen, spend almost one million hired Chinese famous movie star Jingle Xx as their spokeswomen. Not o nly this, Leno company invest large deal of money to sponsor many activities on television and radio to enhance its popularity. As for small business, they will be asked for achieve their customers' need and have large fund to broaden kinds of products claimed by Enclave (2002). Preston (2010) cited Bob Evans 1 OFF than what you have. † It seems hard for small business to follow multinational companies.Small business have tight budget and less popular than large firms, asking over large companies market stocks is difficult for it. Small companies can still exist because of the scale they were chosen. Sheldon small firms are held in CAB, they chose to serve the limited people instead of making less money because much more large companies in there. Small business avoid compete against large firms directly. Multinationals companies have high productivity benefit from their advanced technology. High technology helps those firms make high profits and also help themselves a lot. The productivity advantage of foreign-owned firms is usually en as reflecting multinationals' technological advantage visa–visa domestic firms. † (Marksmen, 2002 cited by Grammar & G ¶erg, 2007). However, advanced technology plays vital role in processing high productivity. Consumers are more willing to pay more to buy those high quality productions, they believe this goods produced by large companies have quality assurance. Another example to support this argument is by Preston (2010) whose study compares the strategic IT companies in the world.He shows that IBM as a technology provider, grabbing consumer market by its innovation product named Smarter Planet. Some software companies in small scale sell some cheaper goods to make profit, but these products cannot run well in the long term. Consequently, people always spend a lot to repair them. Then, fewer people will purchase their products because of lacking of guarantee. It leads themselves face the big problem that b ankruptcy or acquired by large firms. Grammar (2007) quotes Balk (2001) who stated that different roles in different kinds of economies play various roles for productivity growth.To conclude, Multinational reparations have financial strength support them to enlarge their market share. For instance, improving popularity through advertisement and getting high productivity because of their advanced technology. In some cases, small business has no need to fight against multinational companies as they are focus on different market. When small business growing up, they would be take into consideration by large companies because those firms will reduce their market share. Whether small business should compete against multinational ones or not depend on what market they focus on.

Standard Working Hours

Introduction After the implementation of statutory minimum wage in Hong Kong, many people urge the government to have law about standard working hours as employers may use non-paid overtime as a means to minimize the labor cost in order to offset the increase of labor costs caused by the minimum wage. First of all, we would like to talk about the definition of setting a standard working hour. The idea is to set a standard working hour per week. If employees’ working hours are longer than the standard one, employers have to pay additional bonus for the extra working hours.Reason for having standard working hours Regardless of a follow-up action for minimum wage policy, it can ensure better health for employees. The Occupational Safety and Health Ordinance stipulate that employers must ensure the occupational safety and health of their employees. Yet, the problem of long working hour is severe. Taking accounting field as an example, it is common for us to hear the employees in à ¢â‚¬Å"Big Four† have sudden health because of long working hours.Setting up standard working hours can discourage employers to ask employees to have overtime so that employees can have more resting time and more job opportunities may be created as employers may need more workforce to avoid employees having overtime (can’t think of any rebuttal, strong point). Worries from Business sector (EMPLOYERS PERSPECTIVE) Currently, seven of the city’s biggest business chambers have sent a rare joint letter to the government expressing their concerns about this issue.They claimed that this policy may hurt the economic environment in Hong Kong since their labor costs will further increase (increase in labour cost due to the need to employ more workers to compensate for the reduction in working hours per worker. This might involve an increase in wages, administration cost, cost of training etc. Additional cost and resources needed *â€Å"Lau Chin-ho, a deputy chairman of the Federation of Hong Kong Industries, on RTHK's City Forum, said standard working hours could increase business costs and that other alternatives should be explored before drafting a law.He was responding to a government report, released last week, which says employers would need to pay up to HK$55. 2 billion more a year in wages if standard working hours were introduced in Hong Kong. †Ã¢â‚¬  The Labour Department of Hong Kong generated 27 scenarios of the likely impact by altering three elements: a 40 to 48-hour week, overtime pay of one to 1. 5 times regular pay and exemption criteria for staff such as managers and executives. Depending on the scenario, it estimates the employers' additional labour costs at HK$8 billion to HK$55. 2 billion a year, or 1. per cent to 11. 4 per cent of total expenditure on wages. This compares with HK$3. 3 billion a year resulting from a minimum wage of HK$28 an hour. †). The increase in labour cost might adversely affect the consumers si nce employers might choose to shift the price burden to consumers by increasing the price of goods and services. for consumers. Also, as a service-oriented economy, they think that this policy is not applicable in Hong Kong as service industries require more labor force and time. (can mention about the practicality of the implementation of standard working hours.How it might not be enforceable in certain industries with certain nature of work) Besides, the free and open economy in Hong Kong has long been attracting foreign investment. Multi-national corporations are attracted to set up their business in Hong Kong due to the free market and the non-regulated economy. With the implementation of standard working hours in addition to the statutory minimum wage, the higher labour cost and regulated economic environment might deter the inward investment of MNCs, potentially causing an increase in unemployment in Hong Kong.MNCs might choose to set up their business in other countries with relatively lower labour cost, less regulations and more incentives (tax-free). Suggestion to the implementation of this policy legislate standard working hours This policy should strike a balanced benefit between employers and employees. In order to strike non-paid overtime malpractice, it is inevitable to have standard working hours. Yet, the main concern is to set a moderate level of working hours to protect employers’ interest.Pro-democrats call for the level of 40-44 hours per week. Yet, from the survey by SCMP, the average working hours in Hong Kong is 47. 7 per week. So, setting 47-48 hours per week is fair to both sides. The government may consider having evaluation and judgment of optimal level each year for making it acceptable for both sides.
