The Causes and Effects of U.S. Economic Intervention in Latin America

The Causes and Effects of U.S. Economic Intervention in Latin America "We should consider any attempt on [Europe's] part to extend their system [of government] to any portion of this hemisphere as dangerous to our peace and safety," President James Monroe proclaimed in his 1823 State of the Union address to Congress. His famous address, subsequently known as the Monroe Doctrine, declared the Western Hemisphere closed to European colonization and influence, thus establishing an American sphere of influence for the first time in the nation's young history. Shortly before the Monroe Doctrine, the United States formally recognized the new republics of Latin America, beginning the first century of Latin American-U.S. foreign relations with Monroe's address before the House of Representatives on January 30, 1822. The relationship between the United States and its neighbors to the South grew gradually. The United States slowly shifted from acting as an arbiter in Latin American affairs, merely looking out for its best interests from the outside, to a steady, escalating period of U.S.English: Newspaper cartoon from 1912 about the Mon...investment and political intervention. A mounting desire for economic prosperity and profit by the United States government and American-owned businesses led to the shift in involvement and caused the political and economic interventions that characterized the first century of Latin American-U.S. relations, interventions that resulted in American domination in the economic development of Latin America.In the first half of the nineteenth century, the United States exhibited a growing lust for new land. In the age of Manifest Destiny, expansionist fervor denominated American political and social thought. With the establishment of Latin America as the United States' sphere of influence, many Americans looked to their proverbial backyards for new territories. For example, Secretary of State John Quincy Adams suggested Cuba and Puerto Rico as perfect additions to the United States. In a letter to a U.S. diploma t for Spain, Hugh...

Final assessment - Essay Example Due to the rise in cyber attacks and more reliance on eCommerce, the confidence of customers online has been compromised. Quantium reported that Australia’s online sales fell at a diminishing rate, largely caused by ever increasing eCommerce frauds. For example, the growth of Australia’s online sales was 31% in 2010 with fraud rate at 0.6%. However, the online growth rate dropped to 22% in 2012 when fraud rate increased to 0.8% (Demery, 2013). Furthermore, according to CyberSouce (2012) 13th online fraud report, the total online revenue loss due to fraud was estimated at $3.4 billion in 2011. It can be seen that eCommerce fraud has a significant negative impact on online business and this is therefore a cause of concern. Moreover, McAfee as a security vendor, reported that 33% of Australian businesses were involved in a security incident in 2009, which meant a loss of an average $34.000 in revenue and $37.000 for fixing the bug (Timson, 2009). In order to avoid a large proportion of sales being lost due to fraud, Ausmart is in need of a well-developed and secured online network. New Paragraph In many business communities, most of the major transactions are performed online. Online business has become as important and maybe even more important than basic commerce done outside the channel of online arena. Banking transations are done by busy people online as they don’t have the time or the place to go to the banks and perform the transactions by themselves. Credit card purchases, shopping, ordering food, paying bills, performing business transaction, buying books and even paying college fees. People online are now doing all these transactions and therefore eCommerce’s importance has grown and risen significantly in the last 10 years. Owing to this phenomenon, it is imperative for the eCommerce industry to safeguard its business online and to make sure that hackers do not get access to the credit and debit card information of the users. Also, it is crucial that hackers do not block any event and all the transactions carried out online have a safety network, which makes them happen seamlessly. New data collated from about 2 million Australian credit and debit cards reveals the popular suburbs in which e-commerce fraud has been attempted, using internet-connected computers. E-commerce fraud involves a criminal using a stolen credit or debit card to buy goods online. Ecommerce crime is on the rise in Australia and the rest of the world and the hacker community has been very successful at targeting various business enterprises. Ausmart has been trying hard to develop a strong firewalled network and this has taken a significant energy and time from their pursuits. It must be noticed that they have been trying to cope with such threats for a long time and knowing that hackers have been targeting them hwihc has hampered their business negatively, focusing on E-Commerce and making the business as hacker free as they can i s the number one priority right now. Reflections It can be seen from the above paragraphs that eCommerce is significant to the development of business and it is paramount to have a strong cyber security for all the business transactions in order to avid any kind of cyber attacks or malpractices by the hackers which in turn may jeopardize profit margins for the business community.

The Making of a Rebellion Essay Example | Topics and Well Written Essays - 2500 words

The Making of a Rebellion - Essay Example Because of the colonization of the British, the economies of Europe, Africa and the Americas were ties together. These economies were tied together by the triangular trade. Because of the economic conquests and ambitions, wars were experienced among the European themselves and these fighting spilled across into the Americas and thus causing a lot of social and political unrest among the Native Americans. The war politics during this period was characterized by alliances among the Native Americans, the French and the Europeans themselves. This essay discusses the political status of the Native Americans and the Europeans colonial empires in 1750s and the political implications of the Seven Years War among these political entities. The political and economic interests of the Europeans in the Native American region led to conflicts and unrest among the Europeans themselves (Boyer 89). Since the European rule applied to its colonies, the colonialists and explorers who were driven by econ omic conquest ambitions were opposed to the economic and political limitations that the European governor Sir John Andros implicated on them. The colonialists wanted the parliamentary system of governance in Britain because it catered for their colonial and economic interests. As a result, Sir Andros was removed from power in 1688. William of Orange and Mary who became the new governor in Britain promised to provide full support for the parliamentary system of governance. The colonists thus pledged their loyalty to the new monarchs but they wanted to know the kind of governance that they wanted to adapt. The colonialists were surprised to find out that William and Mary also advocated for full control of Britain for all colonial affairs and interests. This led to revolts such as the Catholic Maryland conflicts because the colonialists wanted the British government to limit its control over the colonial affairs. The conflicts among the Europeans had political impacts on the Native Ame ricans. For example the fighting between the French and England over economic and political dominions led to the British and French allies being formed among the Native American tribes (Cobb 103). The natives were therefore involved in the European fighting. The economic and political oppression of the Europeans on the Native American communities eventually led to the Great Awakening because the indigenous people would not stand economic exploitation and political cruelty of the British any more. The political implication of the Great Awakening was demonstrated by the use of religious leaders who advocated for social equality to motivate the native communities to fight or their rights. The social rebellions which characterized this awakening increased within the American British colonies. These rebellions were fueled by the religious questioning of the European political and economic authority in the Americas. These rebellions and revolts against the Europeans eventually led to the Seven Years War (Boyer 92). The formation of alliances among the Native American Indians, the British and the French led to divided political and economic interests which eventually led to the Seven Years War. The diversity of interests caused a lot of tension among the three political entities. The Seven Years War is termed as a global conflict which began as soon as the British and their Indian allies declared war on the French (Cobb 102). Even though the British and t

Critically examine the strengths and weaknesses of the UK's uncodified Essay

Critically examine the strengths and weaknesses of the UK's uncodified constitition - Essay Example However, none of the constitutions in the world countries is known to have perfectly performed its mandate and achieved perfection in its use. Different constitutions in various countries have their own flaws, which limit their effectiveness in those countries. Therefore, although constitutions give direction in governance and highly influence many spheres in a country, they all have their own disadvantages. This is also the case with the constitution of the United Kingdom, which has advantages and disadvantages in the country, due to various reasons, as will be discussed. The constitution of the UK is quite different from those of most countries. While most countries in the world use written constitutions in their governance, the UK continues to make use of the uncodified constitution. By uncodified, it does not mean that none of the elements constituting the constitution is written down. However, in this constitution, one or more elements constituting the constitution might be written down, but there is no one single or whole document, having all the elements of the constitution written in it. Most countries however, as noted, use the written or codified constitution; this includes even the United States of America. Therefore, being among the few countries that do not use a written constitution, considerable attention has been drawn to the significance of the constitution of the UK (Pilkington 1999). The unwritten constitution of the United Kingdom is also referred to as an uncodified constitution. This is a more appropriate term to refer to the UK constitution. Pilkington (1999) emphasizes that, the United Kingdom has different parts of its constitution written down, but what it only lacks is a one document, compiling all those elements of the constitution. Therefore, this means that the United Kingdom uses convention and common

Concepts of Racism and Discrimination

Concepts of Racism and Discrimination Race has been an issue in North America for many years. Eduardo Bonilla-Silva discusses the new racism in his book, Racism without Racists. Bonilla-Silva classifies the new racial discrimination as color blind racism. Color blind racism is then structured under four frames (26). Color blind racism is believed to have lead to the segregation of the white race from other minorities called white habitus. Color blind racism and white habitus has affected many people, whom dont even realize that they are currently affected, have been or will be affected. Color blind racism is an ideology, which acquired cohesiveness and dominance in the late 1960s, explains contemporary racial inequality as the outcome of nonracial dynamics, according to Bonilla-Silva (2). In order to analyze color blind racism, Bonilla-Silva relies mostly on interview data (11) through a 1997 Survey of Social Attitudes of College Students and a 1998 Detroit Area Study (DAS) (12). Bonilla-Silva then breaks down the analysis of color blind racism into four central themes to convey how whites explain a world without racial issues: abstract liberalism, naturalization, cultural racism, and minimization. Abstract liberalism is ideas associated with political liberalism and economic liberalism (28). Abstract liberalism is used for a wide range of issue therefore Bonilla-Silva gives a few different examples of when this frame is used. Rationalizing Racial Unfairness in the Name of Equal Opportunity was used when asking white students if minorities should be provided unique opportunities to be admitted into universities (31). Most whites will state that everyone should have an equal opportunity. Those whites, ignored the effects of past and contemporary discrimination on the social, economic, and educational status of minorities, argues Bonilla-Silva (31). Some of the other views explained are: The Most Qualifiedà ¢Ã¢â€š ¬Ã‚ ¦: A Meritocratic Way of Defending White Privilege, Nothing Should be Forced upon People: Keeping Things the Way They Are, and Individual Choice or an Excuse for Racial Unfairness and Racially Based Choices. The reasoning for abstract liberalism usually deals with equal opportunity, choice and individualism as a defense to white privilege (28). In this frame, it says that you cant allow preferential treatment to certain groups to promote racial equality because equal opportunity is available for everyone. This denies that there are any advantages to whites based from history. Cultural racism uses the they dont have it altogether statement (39). The essence of the American version of this frame is blaming the victim, arguing that minorities standing is a product of their lack of effort, loose family organization, and inappropriate values, stated Bonilla-Silva (40). Kara a MU student states, black people that Ive metà ¢Ã¢â€š ¬Ã‚ ¦I dont want to say waiting for a handout, but to some extent, thats kind of what Im like hinting at, when asked what she thought about blacks lacking motivation (40). Other students used a kinder response to the above question leading to a family structure issue, a lack of education, and financially that blacks had to get a job at an earlier age than whites (41). Cultural racism is the basis of most racism today. The blame game is used in all situations. Peoples egos dont like to believe that the problem occurs because of themselves. If it isnt my fault, it must be yours! All of these frames are not solely separate. Each frame can and are intertwined when talking to most of the students. According to Bonilla-Silva, when minimization of racism and cultural racism are mixed, the results are ideologically deadly (40). Minimization of racism is the belief of whites that race is not the concerning issue. Bonilla-Silva analysis the DAS survey response to the question if the students believed that discrimination was currently a problem. The white and the black groups both responded with a high percentage that they disagreed or strongly disagreed (43). Although whites and blacks believe discrimination is still a problem, they dispute its salience as a factor explaining blacks collective standing, states Bonilla-Silva (43). A more through question was then asked to clarify and blacks believed that discrimination was alive and still is alive (43). Minimization explains, simply, that race is no longer a factor. People sometimes state that minorities are too sensitive. Naturalization is the next frame discussed. Bonilla-Silva believes that this frame was used particularly when discussing school or neighborhood matters, to explain the limited contact between whites and minorities, or to rationalize whites preferences for whites as significant others (36). Students would use words such as natural or thats the way it is when using this frame (37). Bonilla-Silva uses segregation questions to show examples of the naturalization frame. The question would ask why people segregate in schools or where they live. Most would respond, its human nature (39) or I dont really think its a segregationà ¢Ã¢â€š ¬Ã‚ ¦peopleà ¢Ã¢â€š ¬Ã‚ ¦spend time with people that they are like (37). According to Bonilla-Silva, As white neighborhoods develop, white schools follow- an outcome that further contributes to the process of racial isolation (39). This racial isolation Bonilla-Silva calls white habitus. Naturalization says that people self select or are hedonistic but why d o people live in all white or black neighborhoods? This may be due to the long history of segregation or selection of realtors to sell only to a certain ethnicity for a certain area. White habitus is a radicalized, uninterrupted socialization process that conditions and creates whites racial taste, perceptions, feelings, and emotions and their views on racial matters (104). Bonilla-Silva stated, One of the central consequences of the white habitus is that it promotes a sense of group belonging and negative views about non whites (104). Whites interpret segregation as natural or as just the way things are (112). The white race does not have to think about their race because of their dominance. This issue expands when racial segregation occurs. Besides the absence of noticing ones race, white respondents did not seem to see any problems in having an all white neighborhoods. Whites reported being friends with blacks but then later when asked more questions never named a black friend. The research showed that less than 10% of whites actually had black friends even when interracial friendship were available, whites did not cross the color line (108). The impact of white habitus is significant. Racial segregation causes attitudinal, emotional, and political implications (125). Other impacts are the negative effect naturalization and justifications of racial segregation; creates a greater distance between races; lack of empathy and the lack of the reality of colorblind racism (123-125). Colorblind racism affects you, me, and everyone in this world. It is the new racism. Bonilla-Silva states, Color-blind racism forms an impregnable yet elastic ideological wall that barricades whites off from Americas racial reality (181). Not only does it cut white Americans off it allows them to justify what is happening without the harshness of the past (181). Blacks are affected by color blindness, also. They fall within the four frames similar to white but on a smaller scale. Blacks were more direct in their answers but color blind racism had some indirect and direct effects on blacks (172). Color blind racism has shaped some blacks way of thinking about segregation (171). It has allowed some blacks to believe in the culture of poverty concept (172). The struggle against color-blind racism will have to be waged not only against color-blind whites, who cannot see the centrality of race in America, but also against the many slightly color-blind blacks, concluded Bonilla-Silva (172) . In my opinion, the only way to work on the struggle against racial inequality is to continue to talk about it, learn about it, and emphasize the effects of it. Based on the information provided in Bonilla-Silvas book, I can assume that most white are not around to see or hear the racism compared to the minorities that deal with it on a daily basis. Most whites live in primary white neighborhoods so they do not have the opportunity to be aware of racism or sometimes they dont pay attention to it because it doesnt involve them. Sometimes whites say they have black friends but in reality they may have seen black people but never connected with a black person on a friendship level. In order to understand one another and get along, it is important to integrate and learn about each race. Integration of all forms is the key to dissipating racism. The Dynamics of Racial Residential Segregation states, Sociologists and policymaker have long viewed racial residential segregation as a key aspect of racial inequality (Charles, 2003). This article along with many other sociology classes, books, and articles state that segregation is an issue of our past and present. We have made some integration movement since the Apartheid days but this is not enough. We have to level the playing field. If it takes the government getting involved to promoting integrated communities, then I think that is what should be done. People do not like new rules or regulations, so why cant the government promote integration like they promote new federal laws such as the DUI legal limit of .08%. If you move into an integrated community of a certain percent then you will receive a tax cut or some type of benefit. This promotes people to live with other races and eventually it will become second nature . Obviously, the government cannot make those integrated communities communicate but I believe that with time neighbors will start to talk to one another or if nothing else some type of promotion for community block parties, similar to when I was a kid, would assist in the communication process. That is how I remember meeting the neighbors. Community block parties are non-existent now days but I believe they are beneficial to everyone! With a little effort from everyone, we can make it happen, a life without racism!

Gender Diversity: Using Information Technology in Today’s Classroom. E

Gender Diversity: Using Information Technology in Today’s Classroom. What happens when your education is different from mine? When does that invisible line get erased; When youth’s, adolescent’s or adults, male or female encounter the same unique education being taught with nothing being held back just because of gender. In today’s society, teachers and students are connected by using information technology to help expand their knowledge on the issue of gender diversity in the classroom. Gender diversity is not an issue in the United States that just gets swept under the carpet, it’s greater than that, it’s something that has become a worldwide concern affecting the ways in which students are educated in most schools. Issues of diversity are not new. In fact, â€Å"contracting communities are faced with this topic a little too regular, meaning it’s time for change† (Sunderland, 2002). As the reader of this document you will discover the true definition of gender diversity, how it has affected students in numerous ways, what techniques have become greatly appreciated when reaching teachers and students inside of the classroom curriculum, various approaches toward change, a complete understanding of digital divide, a shine of hope and dedication, while striving for a new day. â€Å"Gender differences in ways of learning have been described by researchers observing children as young as three† (Tannen, 1990). When children are young they tend to fight and argue about the same play item.

“Nothing Gold Can Stay” by Robert Frost Essay

â€Å"Nothing Gold Can Stay† by Robert Frost focuses on the idea that nothing lasts forever. The poet uses a central metaphor and personification to express his idea. The poet uses figurative language such as controlling metaphors, personification,and allusions and is specific in his choice of words. â€Å"Nature’s first green is gold† (Line 1) is the first line the is the main example of the controlling metaphor. The color green is compared to gold, which is precious. What he means by this is that things may start out good, but they will not always last. Nothing gold can stay (Line 1) means that things will soon come to an end. â€Å"Dawn goes down to day† ( Line 7 ) by this he means that all the good that happened throughout the day will soon come to an end. There is personification in the poem, which is how Frost is referring to nature as ‘her’ ( Line 2 and 3). Her early leaf’s a flower,but only so an hour, by this he means that good things can last a while, but then will come to a drastic end. He used words like subsides, grief and Eden to represent â€Å"Nothing Gold Can Stay.†( Line 1)Here, he means that everything has to come to an end sooner or later. Eden is a state of happiness, that soon came to an end due to the choices made by Adam and Eve. Frost uses many examples of allusions in this poem such as, the brightness like that of gold’s reflective dazzle, that becomes dulled with time, and the Biblical paradise of Eden that was lost when Adam and Eve fell from the Creator’s good graces. The allusions are to help create a picture in the readers’ mind of what the poem is about, for example with the line â€Å"Nothing Gold Can Stay† (line 1) it is saying that nothing good (gold) will last forever. Frost is specific with his word choice. He uses words like â€Å"Eden sank to grief†( Line 7) Eden sank to grief because Adam and Eve ate some kind of fruit off of the tree they were told not to eat from. When they ate from the tree the Creator forbid them from the garden of Eden. Frost uses many different ways to help put a picture in the readers mind. He uses allusions, personification and metaphors.â€Å"Nothing Gold Can Stay† by Robert Frost focused on the idea that nothing lasts forever. The poet used central metaphors and personification to express his ideas.

Effect of concentration of copper sulphate on the action of amylase to break down starch Essays

Effect of concentration of copper sulphate on the action of amylase to break down starch Essays Effect of concentration of copper sulphate on the action of amylase to break down starch Paper Effect of concentration of copper sulphate on the action of amylase to break down starch Paper There are two ways that we could have consumed copper sulphate. Water pipes are responsible for transporting water, and some of them are made out of copper. Copper pipes can become rusted if there is high sulphate content in the water, basic copper sulphate is precipitated which can grow through the pipe wall creating pit holes [1]. Copper sulphate is also used in some places to treat sewer lines, tree roots are constantly looking for water and organic sources and sewer lines are the perfect site for them. Tree roots will penetrate and damage the pipes which will is expensive to repair. Copper sulfate kills tree roots without killing the tree or other plants [2], therefore copper sulphate is poured into these pipes to kill the tree roots. This way there is a small chance that copper sulphate will leak into the pipes that are used for drinking. Copper sulphate can do a lot of harm to the human body, but very little has been discussed on the effect of copper sulphate on amylase, which is an enzyme that is present in human saliva and in the small intestines, therefore I want to perform an experiment to find out how the concentration of copper sulphate will affect the action of amylase. Copper sulphate Copper sulphate has the formula CuSO4 and is commonly used to control fungus diseases [17], both in agriculture and medicine. According to the Turkish Journal of Zoology (source 16), copper sulphate can inhibit the activity of amylase by 5%. Enzymes- Alpha Amylase Enzymes are biological catalyst, and a catalyst is substance which speeds ups a chemical reaction but remains unchanged itself at the end. [71] Enzymes are biological catalyst because they are globular protein molecules that are made by living cells to speed up reactions inside a living organism. There are three levels of structure of enzyme; the primary, secondary and tertiary structure. The primary structure is the order and type of amino acids that made up the chains. The secondary structure is the folding of the chains into either beta sheets or helix. The tertiary structure is the overall folding of the chains into a three dimensional, globular shape with an active site of a specific shape. Amylase is an enzyme made in the salivary gland and pancreas in the human body. They are used to break down carbohydrates, in other words starch are broken down to sugar or glucose [8]. Enzymes are sensitive to its environment, changes to the pH and temperature will affect the structure and function of enzyme, and therefore these factors have to be kept the same during the experiment. How does an enzyme work? Being a biological catalyst, enzymes work by providing an alternative pathway that has a lower activation enthalpy for reaction to take place therefore speeding up reactions without changing any other factors such as temperature and concentration. Many reactions in the body will not happen at all because the activation enthalpy is too high to reach, therefore the presence of enzymes are vital in every organisms for reactions to take place and to stay alive. The first proposed theory of how the enzyme work is called the lock and key hypothesis, where the substrate is imagined being like a key whose shape is complementary to the enzyme or lock. [72] The substrate will fit into the active site of the enzyme and will form an enzyme-substrate complex. Once this complex is formed, bonds within the substrate will be affected by the bonds in the enzyme; bonds will break and reform, ultimately forming products. The products will then leave the active site of the enzyme, leaving the enzyme free again to accept another substrate. The diagram below shows how the enzyme works. A diagram showing how enzyme works Induced fit hypothesis However this is not completely true, by using technique such as X-ray crystallography and computer assisted modeling [73], we can say that the active site is actually not a perfect fit to the substrate. So when the substrate approach the active site, either the shape of the substrate or the shape of active site will change slightly so they can fit precisely together. In addition, the active site could be modified as substrate interacts with the enzyme. The amino acids which make up the active site are moulded into precise shape which enables the enzyme to perform its catalytic function effectively [74]. The diagram below illustrates the induced fit theory, the shape is different when there is no substrate bonded to it and when there is substrate bonded to it. A diagram showing the induced fit theory Enzyme inhibition There are molecules that exist which act as enzyme inhibitors. They will disrupt the normal function of the enzyme, preventing it from working so the rate of reaction will decrease, or no reaction at all. There are two forms of inhibitions; competitive and non-competitive inhibitions. Competitive inhibition Competitive inhibitors will compete with the substrates for the active sites of the enzyme. This occur when a structure which is sufficiently similar to that of the normal substrate to be able to fit into the active site [75]. As the active site is occupied by the inhibitor, the substrate cannot bind to the active site to get catalysed, so rate of reaction is decreased. However, a competitive inhibition is usually reversible if sufficient substrate molecules are available to ultimately displace the inhibitor [12]. Non-competitive reversible inhibition The inhibitor has not got a complementary shape to the active site of the enzyme; it will bind to other parts of the enzyme instead. The binding of the inhibitor to the enzyme will have no effect on the ability of the substrate to bind to the enzyme, but it makes it impossible for catalysis to take place [76]. Unlike the competitive inhibitor, the rate of reaction will not be affected by the concentration of substrate. Non-competitive irreversible inhibition This type of inhibitor is non-competitive because it has not got a complementary shape that can fit into the active site of enzyme, so will not compete with the substrate for the active site, and the inhibition is irreversible. Heavy metal ions are typical of this type of inhibitors. They will combine permanently to the sulphydryl (-SH) groups. This could be in the active site or elsewhere [13] of the enzyme. The metal ions replace the hydrogen in -SH to form -SX. This will alter the structure and active site of the enzyme permanently, therefore enzymes can no longer catalyse the break down of starch. The diagram above shows the how heavy metal ion, in this case silver, will substitute hydrogen to form -SAg bond. This will alter the shape of active site so the substrate can no longer fit into it to get catalysed. As mentioned above, heavy metal ions are typical of this type of inhibition; copper is a heavy metal ion, so if copper sulphate does inhibit the action of amylase, I can conclude that copper sulphate is a non-competitive irreversible inhibitor. The collision theory The collision theory explains how reactions occur. Two particles can only react together if they come into contact with each other. They first have to collide, and then they may react [21]. They may react because colliding particles need to satisfy two requirements to cause a successful collision or reaction. The orientation of collision When two particles collide together, they need to have the right orientation when they come into contact for them to react. The diagram below illustrates this. There are four different orientations of collisions with enough energy for a successful collision to happen. However only collision 1 results in a successful collision, this is because it has the right orientation to collide with the bond which results in a successful collision, the particles in the other three collisions will simply bounce off each other [21]. Energy of collision The second requirement for a reaction to take place is that particles must collide with a certain minimum energy, called the activation energy [21]. Without sufficient energy, the two particles will simply bounce off each other after they collide. The activation enthalpy of a reaction is shown below. Starch and iodine solution This is a test for the presence of starch in a solution. When iodine solution is added to a solution contatining starch, a blue black colour will form. This is because the amylose, or straight chain portion of starch, forms helices where iodine molecules assemble, forming a dark blue/black color. [15] This means that when starch is being broken down by the amylase, the amylose will start break down too into smaller units, therefore losing the helics shape around the iodine molecules, the blue-black colour will then start to disappear. I can exploit this characteristic in my experiment to dertermine the end point. Using a colorimeter to monitor the light absorbance, I can determine the rate of reaction as it is the same as how quickly the solution decolourises.

South Korean Automobile Market - Non-Tariff Barriers Essay

South Korean Automobile Market - Non-Tariff Barriers - Essay Example The thesis examines the updated trade patterns and determinant of complete passenger and road vehicle trade between the U.S and S. Korea. The main explanatory variable is the effect of S. Korea’s Non-Tariff Barriers (NTBs) on the automobile industry trade with its one of the biggest trading partner, the U. S. The patterns and performance of automobile industry trade and the effects of NTBs in S. Korean car market will be assessed by the Normalized Trade Balance Index, Grubel and Lloyd index and the regression that is by using multiple regression analysis approaches, more specifically. The results of the thesis will highlight the trend of the road and passenger vehicle industry trade and the impact of NTBs on the volume/ value of trade in automobile sectors between the countries since the beginning of the 2000s. S. Korea and the U.S share a great deal of interest in pursuing positive development in the automobile industry’s trade performance. Both countries substantially rely on the profits of the automobile trade for their economic growth and their market sizes are often large. (Dyer & Chu, 2000). Consequently, S. Korea and the U.S Free Trade Agreement is about to come into effect and one of the biggest issues that prolonged the deal while negotiating for the FTA was regarding the automobile, especially passenger vehicle industry trade. President Obama and the U.S industry representatives claimed that the FTA deal regarding automobile trading regime is not fair if they start to trade bilaterally in the current condition and regulation. Opponents of recent FTA provision even claimed that the U.S automakers exaggerate the potential sales in S. Korea of cars produced in U.S. assembly plants (Schott, 2010).  

LLM EC Competition law Essay Example | Topics and Well Written Essays - 750 words

LLM EC Competition law - Essay Example Within the UK Articles 81 and 82 EC have been incorporated into the Competition Act 1998 (CA). The aim of these articles and the CA is to prohibit agreements, business practices and behaviors that have, or are intended to have, a damaging effect on competition in the UK (in the EU for the EC Articles).1 Article 81 prohibits any dealings that will distort competition within the EU, which includes any agreement from insider trading through to companies discriminating to supply goods or services on the basis of preferential businesses. The sale and supply of goods and services should be open to all members of the class that the company deals with. Also the sale of goods and services should be based on fair and open grounds, examples that the Office of Fair Trading and the EC use to illustrate anti-competitive agreements, in addition to cartels, include: The basis that the EC has used to identify what grounds are anti-competitive can arguably be determined as not economic, but more socially based. On economic grounds could such agreements as shown above not be a way to create a more competitive market, because if the present competitors agree to limit output does this not open the door for new businesses to open up in order for supply to meet the demand. Therefore it is questionable whether the current system of law is really dealing with what is economically competitive on economic grounds3. This is even more apparent with Article 82 EC, which deals with identifying what equates to abusive behavior by a company in respect to EC competition law. In order to be abusive under the company must be in a dominant position, which raises a question on the fairness of this article because if a company is not in a dominant position why is it not abusive This seems to be more of a social rather than an economic factor, because it means that if you are NOT a powerful and dominant company you can do as you wish.4 This illustrates that the grounds that EC law is determining on abuse in fact favors one sector of the economy over others, i.e. the underdogs. Is this not an abuse of competition law, because in certain instances dominant companies are a natural part of the industry's landscape, e.g. water, natural resources and fuel. This indicates that the current approach to determining a breach of competition law is in fact ironically a breach itself. The definition of dominance comes from the cases of United Brands5 and Hoffman-La Roche6 where the ECJ (European Court of Justice) defined the concept of dominance as: A position of economic strength enjoyed by an undertaking which enables it to prevent effective competition being maintained on the relevant market by affording it the power to behave to an appreciable extent independently of its competitors, customers and ultimately of its consumers.7 It is commendable that the ECJ indicates the need to protect the interests of the consumer; however is this determination on the basis of the economic grounds of
