Cofer And Staples Essay Example

Cofer And Staples Essay Example Cofer And Staples Essay Cofer And Staples Essay Also their lack Of English they had and the differences between her race and the American race. Both of the writers are informing readers of how deeply Puerco Ricans and blacks are stereotyped. Moreover of how their race is being judged and discriminated against just from what they see and hear. First of all Staples explains how white women and other people view him by the color of his skin and appearance. In the essay he states a white woman is walking a distance from him but she gives off a negative vibe by glancing behind her. She avoids eye contact from him and made her think he is up to no good. However Staples stated he is A softy who is scarcely able to take a knife to a raw chicken. This demonstrated to him that she was judging him by the color of his skin, black a dark color used to depict African Americans. It showed Staples that white women would depict him as dangerous. It also showed him that people stereotyped African Americans as the people who are up to no good. In another subject Coffers essay also had the same conflicts dealing with race, stereotype, and ethnicity. It conveyed how Puerco Rican women were viewed and misunderstood as well as being labeled by people outside her race. In the essay she also talked about wanting to fit in but she could not because of her tradition and culture. The differences between what she had to wear and what American people wore was stereotyped as well. This is because American people dressed up modernly and dull but Puerco Rican girls stood out too much. The way they dressed was too flashy and too vibrant. Coffer also conveyed how Puerco Rican women were portrayed by movies Americans would watch. She explains that Americans would just take what they see from a movie and assume that Puerco Rican people are exactly how they are seen in movies. When they do not know exactly nothing about Puerco Rican people. Another thing she pointed out was how Americans assumed that Puerco Rican people were uneducated and had a lack of English speaking. Although Coffer wanted to imply that even though she had a hard time growing up she still succeeded her goals. However Americans are just used to judging new people and new things as either dumb or too flashy or worse. One idea about racial and ethnic stereotype that is important is that Americans have their ways of judging as well as other types of cultures and race doing the same. Although ACH race and ethnicity is equally the same just they are viewed differently. The Puerco Rican women are viewed as uneducated and do not exactly know how to dress well. However they can do just the same as any other person from any race. They can succeed in what they want to pursue without taking harsh judgments and not caring about others views on themselves. They can fit in if they wanted to by telling people outside of their culture and race what type of person they are. Furthermore Staples is viewed as dangerous because of his skin color. However he implies that people are just judging him and believing what they hear and see. Making that one race or culture look bad even though people do not know anything about them. Another important thing is that both writers are trying to ideally show that people tend to stereotype any race and any ethnicity that is out there. They talk of how they look, their education, and two big ones are the skin color and the way their English is. In Staples essay he evidently shows how white women specifically view him. One where he Was just walking behind the woman and she grew suspicious of him and had the thought of him being up to no good. It demonstrated the way white women judged black men. He also implied how people would just judge a person by the skin color assuming that, is the way the person is without even knowing anything about the person. Staples also stated how his presence on another effected the way people viewed him. Also how the reaction of others affected him also in return. As for Coffer she used evidence that stereotyped her appearance and her education. She implied that all Puerco Rican women were stereotyped by the way the dress and the way they spoke English. It had an effect on her that she could not fit in with the community. All in all both writers had the same conflicts that they held to heart. It affected them in many ways. They were being judged either by their appearance or the color of their skin. As well as the way they spoke English or even their education. They are alike because both felt that they wanted to fit into the community. Coffer and Staples experienced the judgments of others on themselves and it affected them in the same way too. They both were a race where people on the society would judge harshly. Staples was judged based on his looks as well and Coffer had the same thing affecting her. However they both implied that the judgments made on them provoked them to succeed either way. They both conveyed that even though they had it cough they still succeeded and they did not let the views of others affect them so harshly.

Gobal Financial Investment Essay Example | Topics and Well Written Essays - 750 words

Gobal Financial Investment - Essay Example This paper illustrates that the first option available to the UAL, Inc. is to borrow the required investment amount of $500 million in the local currency that is US Dollars. At the initiating stage of the loan agreement, the company has to pay an underwriting fee of 0.5% of the total principal amount and therefore, it is added to the cost of borrowing. This option does not involve in exchange rate risk, however, there is surely an element of the change in the inflation rate which could affect the time value of the currency over a period of 10 lean years. However, this element has been ignored for this report. The company can borrow $500 million at a rate of 11% with two semiannual interest payments due in June and December every year. This implies that the rate which is quoted annually needs to be adjusted for semiannual payments and the number of payment periods will also be adjusted for the same reason. The interest rate adjusted will be 11% divided by 2 which is equal to 5.5% of t he total principal amount to be paid semiannually. The total number of payment periods will, therefore, be 20 as the loan period is for 10 years. Moreover, there are no principal repayments during the 10 years tenure and the whole amount of $500 million is to be settled at the end of the loan term. By placing the available information in the following table and calculating the future value it can be ascertained that the future value of borrowing under this option is $1,458,878,745. This value will be compared with the future value obtained under the second option. The second option available to the company is to borrow $500 million denominated in Japanese Yen from the leading Japanese Bank. The current exchange rate between US Dollars and Japanese Yen is at 250 which will result in borrowing of JPY 125 billion at an annual interest rate of 5%. Since the interest payments are semiannual therefore this rate has to be adjusted along with the number of payment periods as in the previous option.

Social Context Account Essay Example | Topics and Well Written Essays - 1500 words

Social Context Account - Essay Example For one to look back at the past and analyse its effect in life today, the present has to be favourable according to the individual in question. This means that if the past influenced one’s life so badly that the present is damaged, only counselling or other forms of therapy can remedy the situation and enable one to look back at the events of their past.1 Depending on an individual, the social environment one grows in can make or break one’s character. For instance, some people are discouraged by discriminative backgrounds till they psychologically believe they are not worth better treatment. On the other hand, others consider maltreatment as a challenge which if overcome, one emerges not only a stronger, but also a better person. Due to the unpredictable nature of a child’s reaction to the social environment, there are many organizations committed to ensuring that children are protected from harsh social conditions. In addition, many governments have signed tre aties and passed laws to protect young citizens.2 _____________________________ 1 A James, and A Prout (eds), Constructing and Reconstructing childhood: contemporary issues in the sociological Study of Childhood, Falmer Press, London, 1997. 2 R Appignanesi, and O Zarate, Freud for Beginners, Icon Books, Cambridge, 1992. Background information My parents were born and brought up in Bangladesh after which they moved to London, UK. I was born on April 4, 1989 in London where I have lived ever since. The UK and Bangladesh are countries with many contrasting characteristics that are mainly due to their geographical locations, economic, political, and religious practises found in the two countries. Bangladesh is found in southern Asia while UK is situated in northern Europe. Bangladesh is mainly an Islamic country while the most dominant religion in the UK is Christianity. In society, religion plays an important role in how the society operates since it provides a basis for moral and ethi cal standards. In the UK, the church and government are separate entities and that is why the society in London is considered secular and has markedly different characteristics compared to that of Bangladesh where religion determines the kind of lifestyle people live. Comparison between UK and Bangladesh Christianity, mostly Anglican, is the dominant religion in the UK while Bangladesh is mostly Islamic. The cultures of the two countries are composite, having components derived from all over the world. Both countries are members of the UN and have signed the United Nations convention on the rights of the child (UNCRC) which seeks to ensure that minors enjoy basic rights and are protected from unfair treatment. However, the countries differ in the way they enforce these laws since in Bangladesh, children are still recruited into the armed forces among other forms of mistreatment. This means that a child growing up in Bangladesh is likely to be affected by these vices directly or indi rectly. On the other hand, the UK is strict in assuring her citizens of their rights and, therefore, children enjoy more rights and freedoms compared to their Bangladeshi counterparts. 99 percent of the population in the UK is literate as compared to a mere 43.1 percent in Bangladesh. Education has a huge impact on how people relate to each other and their interpretations of everyday phenomena. On the other hand, the educated population in UK is more corrupt at 7.7 perception index compared

In the USA, Financial Accounting Standard Board (FASB) develops GAAP. It is a private body that sets both broad and specific rules (Wild, 2005). Securities and Exchange Commission (SEC) is another government entity that sets reporting requirements for companies that issues stock to general public. In addition to above-mentioned two bodies, there is another board called International Accounting Standards Board (IASB) that establishes International Financial Reporting Standards. This is an attempt to establish a harmonious and consistent system of accounting throughout the globe. However, IASB cannot impose these rules to organizations. The main objective of GAAP is to make financial information "relevant, reliable and comparable" (Wild, 2005). Managers' decisions are highly affected by the relevant financial information. Adherence to GAAP offers reliability to financial information and wins the trust of the user. Good understanding of these principles is necessary especially when you are comparing the performance of two or more companies, especially when the companies belong to different industries or countries.

temperature on the activity of liver

temperature on the activity of liver Introduction: Catalase is a common enzyme found in living and it acts as a protective mechanism for delicate biochemical machinery of cells. The enzyme catalyzes the exothermic decomposition of hydrogen peroxide to water and oxygen. 2 H2O2 → 2 H2O + O2 Hydrogen Peroxide is a by product produced by many living organisms during the process of metabolism. Hydrogen Peroxide is a very toxic substance (a power oxidizing agent) to cells and must be broken down in order to protect the cells from subsequent damage. Aim: The aim of the experiment is to investigate the effect of varying temperature has on the rate of enzyme catalyzed reaction. The focused reaction is the decomposition of hydrogen peroxide with the enzyme catalyze. The presence of catalase can be demonstrated by dropping a small piece of fresh liver tissue into dilute hydrogen peroxide solution. In this experiment, pieces of liver tissue will be put into different temperatures of water for 5 minutes. After that the liver tissues will be placed into separate solutions of hydrogen peroxide and the amount of oxygen gas produced in a minute will be measured using a gas syringe. Hypothesis: Temperature is a measurement of the degree of hotness or coldness of a body or environment. More specifically, it is a measure of kinetic energy in a sample of matter. On a molecular level, temperature is the result of motion of particles which make up a substance. As the temperature increases, the motion also increases. The motion may be due to external energy applied to the particle of internal energy from the vibration of the particle. As temperature is increased, molecules have increased active energy and reactions between them and the probability that the particles will collide with each other will also be greater, this increasing the rate of reaction. In chemical reactions, for every 10 °C rise in temperature, the rate of reaction approximately doubles. This property is known as the temperature coefficient of a chemical reaction. However in a enzyme catalyzed reaction the effect of temperature is more complex, for proteins change shape by heat. There are many factors that can affect the structure of a protein such as temperature and ph. When a protein is exposed to heat, it causes the atoms to vibrate violently, breaking and disturbing bonds within the protein, therefore changing the chemical characteristics of the protein. I hypothesize that as the temperature of the water bath that the liver tissue is exposed increases; the amount of oxygen gas liberated will also increase up. I believe that there will be an optimum temperature for the enzyme and going pass the optimum level will cause a drastic decrease in enzyme activity (less oxygen gas will be produced). Since catalase is found in almost all living things, including humans, I predict that the optimum temperature for catalase will be Variables: Independent Variable Temperature of water bath liver tissue is placed In ( °C) Dependant Variable Volume of oxygen produced in a minute (ml/min) Controlled Variable Concentration of the Hydrogen Peroxide Volume of Hydrogen Peroxide Mass of liver tissue The concentration of hydrogen peroxide must be kept constant because according to the Collision Theory proposed by Max Trautz and William Lewis in 1916 and 1918, increasing the concentration, increases the chances of particles hitting each other. The volume of hydrogen peroxide should also be kept constant. Increasing the volume of hydrogen peroxide increase the substrate concentration and thus increasing the rate of reaction. Finally the mass of liver tissue should also be kept constant to try control the amount of enzyme molecules present. Increasing the number of enzymes means there are more active sites present and substrate molecules do not have to â€Å"queue up† for access to an active site. Ultimately increasing enzyme concentration can also result in an increase in rate of reaction therefore the mass of the liver tissue should also be controlled.

Dilute with water and wash liquid. Hydrogen peroxide should be stored in a dark brown bottle and care must be taken when removing the cap as it is possible that pressure may have built up inside it. Method: Draw up a suitable table or tables to record the results. Carefully cut 7 pieces of cow liver tissue using a knife and a cutting mat. Weigh each piece of liver tissue carefully on the electric balance. Make sure each liver tissue weighs roughly around 0.5 grams. Place each liver tissue into a separate boiling tube and add 40ml of deionized water to each boiling tube once the liver tissue is situated at the bottom of the boiling tube. Place the heating mat on the table with the tripod on top of the heating mat. Gently place the gauze on the tripod. Once this is done, place the beaker on the tripod and slowly heat up the water with a Bunsen burner. Place a boiling tube with a liver tissue sample into the water and put a thermometer in the tube. Heat the beaker until liver sample solution reaches 70 °C. Measure temperature of water with a thermometer. After that, carefully measure out 100ml of hydrogen peroxide with a measuring cylinder and transfer the solution to a 250ml conical flask. Connect one end of the gas delivery tube to the gas syringe and the other to the conical flask Remove the liver tissue from the boiling tube with a pair of tweezers and place it into the conical flask with the hydrogen peroxide. Quickly cork the conical flask once the liver tissue is dropped into the solution of hydrogen peroxide. Beginning timing the time once the liver tissue touches the hydrogen peroxide solution. Stop the stop watch after 1 minute and record the amount of gas produced. Read off the gas syringe. When the reading is taken, remove the cork and dispose of the hydrogen peroxide in the chemical waste container. Repeat the above steps until data points from 10 °C to 70 °C are recorded.. For readings below 30 °C, cool the liver tissue sample with an ice bath.

The graph clearing shows that as the temperature increases, the amount of gas also increases up to 60 °C. From 60 °C onwards, the amount of oxygen gas produced decreases drastically and there is a downward slope of the curve. Discussion: From the data obtained, there is an increase of oxygen produced as the temperature of the water bath increases. This trend however only applies to the data points from 20-60 °C. At 70 °C however, there is a significant drop in the amount of oxygen gas produced and at 80 °C, the amount of oxygen gas produced is less than 5ml. From the graph, the relationship is clearly represented. Up to about 60 °C the amount of oxygen gas produced increases and ten-degree rise in temperature is accompanied by 6-7ml increases in oxygen gas produced. The amount of oxygen gas produced decrease at high temperatures as shown from 70-80 °C. So as the temperature rises, the amount of enzyme progressively decreases and the amount of gas produced is less. As a result of these two effects of heat on enzyme, there is an apparent temperature for an enzyme. Using the graph, the optimum temperature of catalase is approximately at 60 °C. The properties of a protein greatly depends on its three dimensional shape of the molecule. Exposure to heat causes the atoms to vibrate violently and this can cause bonds within the protein between different amino acid to break, resulting in a loss of the proteins biological properties. This is known as denaturation of a protein. Heating causes a proteins biological properties to change such as optical rotation, shape of active site and bonding. The active site of the enzyme is what defines the enzyme. If the active site changes, the substrate molecules will no longer fit the active site of the enzyme. This is shown in the diagram below. A proteins stability depends primary on the hydrophobic effects and to a lesser extent, by the interactions between polar residues and by other types of bonding. There are four levels of protein structure each playing a significant in the stability of the protein. The primary structure of a protein is the sequence of amino acid residues attached by peptide linkages. Proteins differ in the variety, number and the order if their constituent amino acids. Changes is just one specific amino acid in the sequence of a protein can alter a proteins property. The secondary structure of a protein develops when parts of the polypeptide chain take up a particular shape. The most common shapes are either coiling to form ÃŽ ± helixes or into ÃŽ ² sheets. The tertiary structure of a protein is the distinctive and precise structure, unique to that specific protein. This is usually the result of further folding and interactions within the molecule. The shape is held together permanently by four differ ent types of bonds: hydrogen bonding between hydroxyl and ketone functional groups, Van der Waals forces between neighboring atoms, disulphide bonds between two cysteine side chains and ionic bonds between oppositely charged ions. The stability of a protein is dependant of the balance of these three structures. Altering the balance of forces that maintains the native conformation of the protein will lead to denaturation. Conclusion: The hypothesis put forth before the experiment was correct. As the temperature of the water bath that the liver tissue is exposed increases; the amount of oxygen gas liberated will also increase up to a certain level. That level would be the optimum temperature of the enzyme and the optimum temperature of catalase deduced from the experiment is approximately 60 °C. Pass the optimum temperature, the amount of oxygen gas produced drastically decreases as the enzyme is starting to denature. At 80 °C, the enzyme is almost fully denatured and only a small amount of oxygen gas is produced. The literature value for the optimum temperature of catalase in human is about 37 °C which is the body temperature of a typical human being. The liver sample was taken from a cow and both cows and humans are able to regulate their own temperature. From this we can deduce that the optimum temperature of catalase for a cow should be roughly similar to a humans and somewhere around 37 -40 °C. The op timum temperature obtained from the experiment is 60 °C, this suggests that there may have been deviations or variations within the data. Limitation to Experiment: There are several limitations to our experiment to the experiment. One of the main limitations was controlling the temperature of the water baths. The temperature began to drop gradually once the boil tubes were placed into the beaker. This may have caused deviation and variations within the data. Another limitation was that the experiment was only repeated 3 times and there may still be room for anomalies and errors. Evaluation: As long as the temperature of the water baths were kept constant and the amount of gas produced was measured and read correctly, a good approximation of the optimum temperature of catalase in a cow can be found. However there are several key improvements that can be made. When the liver tissues were cut a lot was wasted and some of it got stuck to the spatula and to the top of the test tube. To compact the problem in the near future, the liver tissues stuck onto spatula could be washed off using a tiny amount of water or shook gently to try remove some of the liver tissue. The method for collected the oxygen gas could also have been improved. Some gas was lost due during the time it took me to insert the bung into the test tube. To minimize the amount of gas lost, have a partner put the bung on for you while you drop the liver tissue into the measuring cylinder. The temperature of the water baths started to drop after a few minutes and this may have lead to some slight deviation with in the data. In future make sure that the temperature of the water bath does not change too significantly. A slight modification would be to cover the beakers with a lid to prevent air from escaping. Another problem that arose during the experiment was keeping the temperatures of the water baths constant during tests and between trials. The problem was that different temperatures of liver samples were tested and it wouldnt be feasible to use a electronically controlled water bath to perform each test. The result was that a Bunsen burner was used but this creates several problems. It was extremely difficult to get exact temperatures and maintain them throughout the experiment. In future, the use of a heating plate would be more practical so as to prevent drastic changes in temperatures. To improve the experiment it may be better to use a solution of catalase rather than a liver as a source of catalase. By using a solution, the concentration and volume could be controlled and would be the whole experiment into a fairer test. Overall the results obtained have helped support the hypothesis put forth before the experiment. Finally the experiment could have been repeated a few more times so that a better average could be drawn from the data, resulting in a more reliable and accurate conclusion. References Clegg, C. J.

Diversity in Crash Essay

The movie Crash (2004), directed by Paul Haggis, is full of different racisms, social and multicultural differences. There are seventeen different characters in this movie ranging from different race, gender, social class and ethnicity. These are stereotypes that people face every day of their lives. Crash really shows the assumptions that we make of others and how people of different backgrounds interact with each other. The movie really made me realize how I act in these types of situations. This movie not only shows the multicultural differences in society, but I think places an emphasis on it within the criminal justice system. In one of the first scenes we see a Persian man with his daughter in a gun store trying to purchase a gun. The owner of the store who is a white male has a very negative attitude towards the man and his daughter. His attitude and gestures really show the negative stereotypes towards the Persian race. The store owner made remarks regarding the attacks on 9/ 11. The store owner is associating them with the Arabs that actually attacked the U.S. Anyone from the Middle East seems to fall under the same category for the store owner. There are many stereotypes that have been around for years, no matter how hard we have tried to get rid of them. Sandra Bullock’s character had made the statement, â€Å"If a white woman sees two black men walking towards her and turns the other way, she’s a racist. Well I got scared and didn’t say anything, and the next thing I knew, I had a gun shoved in my head!† This was a turning point for her and her beliefs. Although the men who shoved a gun to her head were black, she started to be racist towards anyone that was not white. A Hispanic male was changing the locks on her house and she automatically started throwing insults at him. Sandra figured that he would make copies of the keys and come back and break into her house. The way Sandra acted; I think is how most people may respond to situations like that. This can be especially true for the police departments. When an officer has a bad experience with another race while on duty, it can affect other situations the officer may come across with the same race. The officer may think that everyone of that race is the same way. I have always believed that racism, social and multicultural differences were a result from how we were brought up. I believed that if your parents were racist, then you too would be racist. At first, Matt Dillon’s character showed the signs of this theory. Dillon showed that he had a very close bond with his father, which I assumed where he learned his behavior from. This would end up being the furthest from the truth. Dillon’s beliefs come from working on the LAPD for many years and the frustration that he would have at his father’s doctor’s office. At the doctor’s office, Dillon believed that the lady was not trying her hardest to help his father, because she was black. Police corruption is not something that the public hears about a lot. Usually, this is something the police departments try to keep out of the media. There was a situation in the movie that really shows the corruption that can happen. Matt Dillon’s and Ryan Phillips characters are partners on the police force. One night on patrol they pulled over an SUV with a black couple inside. Dillon had offered to let them go without a ticket if the woman would perform sexual acts. As Ryan was looking on at the situation he saw that Dillon was groping and touching the woman inappropriately. While Dillon was assaulting the woman all her husband could do was look on. If he had tried to stop it he would have been arrested. I hate to think this happens, but I know that it does. Ryan decided that he no longer wanted to be Dillon’s partner. He went to his boss and tried to give reason as to why he wanted out. Ryan had to cover what Dillon did and come up with a different reason as to why he wanted a new partner. In our book Ethics and Morality in Criminal Justice explains and gives many examples of sexual misconduct. At the bottom of page 188 it talks about how officers would go â€Å"bimbo hunting.† This would include sexual harassment towards women out drinking, prostitutes and homeless women. These types of situations really show the corruption in a police department. Police chiefs do not want to bring negative attention to their force, so they usually end up covering up what is going on. As far as my personal experience, growing up in Arizona I was in contact with many different races and cultural back grounds. I would like to say that I do not judge people and give them a chance. However, this would not be true. I think we really do use previous experiences and judge others from those. If I were a police officer, I think it would be really hard not to carry over my experiences each time I have a run in with a certain race. I do know that if I witnessed police corruption going on that I would bring it to someone’s attention. We arrest those who sexually harass or rape others that are not on the police force. Therefore, I would not let them get away with anything just because they are an officer. Trouble facing stereotypes can happen anywhere. It is not restricted to race and cultural backgrounds. There are stereotypes against age, social class, gender and there are many more. These stereotypes can cause friction within the same ethnic backgrounds. Until our society takes control and changes these, then there will always be prejudice. The movie Crash really makes us take a look ourselves and how we behave and how much we are all alike in reality. There are so many different scenes in that movie, that there is at least one that we can all relate to.

American Psycho vs American So essays

American Psycho vs American So essays American Psycho vs. American society Director Mary Harrons American Psycho, portrays a man who appears socially, financially, and culturally successful to the outside world. But the same culture that he strives to conquer seems to lead him to horrible acts of violence. The mere idea of committing the acts of violence shows the downfalls of our current society. Some of these downfalls may be loss of respect for others, and a money driven mentality. Driven by Greed, Harrons Patrick Bateman is continually striving for improvements in his physical appearance, financial/social status, and masculinity. This continual need for improvement and desire for perfection by Patrick mirrors our American work ethic. American Psychos Patrick illustrates how his economic and social stature can mask his serial killer mentality. In a scene where he discusses movie reviews with his secretary while holding a nailgun to the back of her head. She has no idea of the nail-gun and thinks he is a normal, sane person because of his high social status. As he lures women back to his fancy apartment, he is using his money and nice things as a tool to commit these acts of violence. This ironic twist of a mans mentality relates to how what Newitz refers to as economic performance anxiety could force someone to do strange things as a result of a fear of imperfection. The interest of watching the cinema of serial murders may relate to an insanity caused by our own culture. Our capitalist society, although leads to some very financially successful people, may have deep emotional drawbacks to those that choose to participate in its workforce. The book Mythologies of Violence in Postmodern Media, edited by Christopher Sharrett discusses a desire to consume infinitely that is present in our current economic societys mind. This need for things, such as expensive cars, and nice houses logically lea...

Assessment of a social networking company Essay

Assessment of a social networking company - Essay Example Among these sites, MySpace.com is undoubtedly the market leader. MySpace.com accounts for an impressive 47.4% of the total market share. Facebook is second on the list with the market share of around 18%. Orkut and Flickr are next in the list and they account for almost 7% of the market share, each. (MC Marketing Charts) Many experts claim that the websites operating in this industry may experience a fast growth and an eventual chill if they do not develop long-term strategies. For example, new websites can easily take away the market share of old, if they do not innovate and strategize their operations. To support their argument they give the example of Orkut. In the past, Orkut was growing at a very fast rate but it did not innovate as result new websites came and experienced a massive growth at the expense of Orkut. It is also believed that with the passage of time, as the industry matures, these sites are going to attract more and more traffic. This large turnover will encourage companies to advertise more on these websites. As a result, these websites will experience an even larger growth in their revenues. As a result, many big brands consider advertising on these sites as a better way to grab the attention of "target market" towards their products. (Nielsen) This industry, in the recent times, moved from niches to become one of the most coveted sectors. This growth has also caused creative destruction for the other mediums of marketing like radios and televisions. Earning Revenue from Advertising: The boom in social networking has blossomed opportunities for advertisers to start using these networks as a vehicle to reach their target market. For e.g. in Italy, Maserati is using social networking websites to reach out to its customers. However, if we analyze the situation, we can reach a conclusion that those advertisers who want to advertise on social networking sites have to overcome a few challenges. Though, advertising on the social networking websites is increasing, but it is still very less, compared to the number of people who use these networks. (Review) The diversified nature of the environment means that standard ads won't be able to succeed in this market, and it is imperative that different approaches should be tried to find out the mindset of people who use these networks. Since, advertising all over the world is losing credibility, it is better for these companies to advertise with a more humble and candid perspectiv

The Effects of Economic Aid to Third World Nations Term Paper

The Effects of Economic Aid to Third World Nations - Term Paper Example This question has been repeatedly being asked and emphasized on by various scholars over a long period of period. In 1972, Papanek was the first one to develop a constructive relationship between growth and aid. In 1985, Singh also seconded Papanek that a cohesive relation exists between the economic growth and aid in Third World nations. In 1993, Synder also propagated the ideas of Papanek and Singh but taking into consideration the size of the country. In 1997, Dollar and Burnside acknowledged this positive relation on the premise that it works nicely if the country is meticulous in making policies and it also implements policies according to donor countries, policymakers in beneficiary’s countries and also considers multilateral support firms. In 1999, El-Kaissay and Fayissa profound into this thought and reap the same positive correlation. (Duc) Aids come in several forms; for instance food assistance, military aid, humanitarian emergency support, etc. The growth aid has a lways been recognized as important for helping poor nations of the world to bring them out of impoverishment. The affluent nations of the world decided to give aid of 0.7% of their Gross National Income to poor nations in 1970 as an official global development support each year. But this target has never been achieved. Regardless of the fact that countries have given billions of dollars in cash to poor countries each year they have never met the standard set by them. Some scholars believe that aid has a pessimistic affect on the development of developing countries. In 2000, Knack argued that excessive aid destroys the quality of government, exploits it, and augments the corruption in that region and thus growth is affected negatively. In 2003, Roodman, Levine, and Easterly examined a huge sample size to test the premise of Dollar and Burnside, and the result they found didn’t quite support the positive relation proposed by Dollar and Burnside. (Schoolland) Every rose has a th orn. And thus aid does not come for free. It bears an expensive price to the developing nations. Mostly, the top most condition for aid is that the recipient country must buy over expensive services and goods from the donor nations. Also, the amount of aid is planned and set by affluent countries that following their protectionist policies restrict poor nations to access the market. Most assistance does not really go to the poor nations who are in most need of it. Furthermore, huge projects or enormous striking strategies are deemed to failure to assist the susceptible as mostly, money is used the wrong way. On the contrary, it has also been observed that developing countries with strong economic policies and high-quality governmental institutions have augmented their growth with aid rather than without it. The Gross Domestic Product of countries receiving aid has increased by 2.7% per capita in contrast to countries not receiving aid, with 0.5% per capita. But, some countries who o nly received some aid have achieved a 2.2& per capita of growth. It all basically depends how the aid is utilized; a sound management and high-support by rich countries leads to 3.7% per capital Gross Domestic Product according to World Bank. (Bovard, 1996) Let’s look at the impact foreign aid has on some countries. The current experience of South Asian countries is exemplary. With foreign aid, Bangladesh has
