Stereotyping Today s Culture Stereotyping - 979 Words

Stereotyping in Culture. The definition of stereotyping according to dictionary.cambridge.org is: An idea that is used to describe a particular type of person or thing, or a person or thing thought to represent such an idea. (1) Some psychologists argue that it is a â€Å"natural† aspect of human behavior, which can be seen to benefit each group because it helps in the long-run to identify with one’s own ethnic group and so find protection and promote the safety and success of the group. There is no evidence for this view, however, and many writers argue that it is merely a way of justifying racist attitudes and behaviors. (2) www.simplypsychology.org In the age of political correctness stereotyping people is coupled with prejudice, discrimination and racism. Consequently one can no longer possess a stereotypical tendency without being persecuted as a racist or one who promotes hate and discrimination. The idea of stereotyping people comes from a negative connotation of one’s race, religion, regional, social, and economic standing. When a positive connotation is applied in the same manner as stereotyping it is labeled as heritage. Although stereotypes generally have negative implications, they aren t necessarily negative. Stereotypes are basically generalizations that are made about groups. Such generalizations are necessary: in order to be able to interact effectively, we must have some idea of what people are likely to be like, which behaviors will be consideredShow MoreRelatedStereotyping in Marketing: Good or Bad?1413 Words   |  6 PagesStereotyping in Marketing: Good or Bad?

Modern Trends in Computer Hardware - 2782 Words

LATEST TRENDS IN COMPUTER HARDWARE LATEST TRENDS IN COMPUTER HARDWARE INTRODUCTION 1. The history of computing hardware is the record of the ongoing effort to make computer hardware faster, cheaper, and capable of storing more data. 2. Computing hardware evolved from machines that needed separate manual action to perform each arithmetic operation, to punched card machines, and then to stored program computers. The history of stored program computers relates first to computer architecture, that is, the organization of the units to perform input and output, to store data and to operate as an integrated mechanism. Secondly, this is a history of the electronic components and mechanical devices that comprise these units. Finally, we†¦show more content†¦BUS TOPOLOGY 8. In a network, the master scheduler controls the data traffic. If data is to be transferred, the requesting computer sends a message to the scheduler, which puts the request into a queue. The message contains an identification code which is broadcast to all nodes of the network. The scheduler works out priorities and notifies the receiver as soon as the bus is available. 9. The identified node takes the message and performs the data transfer between the two computers. Having completed the data transfer the bus becomes free for the next request in the schedulers queue. a. Advantage: Any computer can be accessed directly and messages can be sent in a relatively simple and fast way. b. Disadvantage: A scheduler is required to organize the traffic by assigning frequencies and priorities to each signal. THIRD GENERATION BUS 10. Third generation buses have been emerging into the market since about 2001, including Hyper Transport and InfiniBand. They also tend to be very flexible in terms of their physical connections, allowing them to be used both as internal buses, as well as connecting different machines together. This can lead to complex problems when trying to service different requests, so much of the work on these systems concerns software design, as opposed to the hardware itself.

Explain How the Solow Growth Model Would Analyse the Effects of a Fall in the Household Saving Ratio Free Essays

string(98) " in which neither will be prepared to move from the original position hence blocking cooperation\." In this essay, I will focus on two important aspects. The first is to give a brief historical outline of the Solow growth model. The second thread runs express how the outline on the Solow growth model might explain the effect of a fall in the household savings ratio. We will write a custom essay sample on Explain How the Solow Growth Model Would Analyse the Effects of a Fall in the Household Saving Ratio or any similar topic only for you Order Now My essay will be guided by the diagram provided on which I have to make specific references and to think through as well as explain the various steps of the Solow growth model and what this would mean for economic growth. Without dismissing earlier attempts, the foundations upon which modern economic growth theory rests on the foundations put by US economist Robert Solow (1924-) in the 1950s and 1960s. The Solow growth model is very neoclassic in that it focuses primarily on the supply side. The Solow model seems to implicitly assume that, as long as the supply of goods increases, economic growth can be attained. In this way it is apparently different from Keynesian models of which focus is on the demand side of the economy such as inflation and unemployment. One of the major central reason by Solow to come up with the Solow model came from the desire to know what happens in the long run to an economy in which capital accumulation is taking place. In pursuit of an answer to this question Solow came up with a degree of mathematical and analytical work. Solow pursued a model of an economy in which one has a single good that can be consumed or invested, and he says the total output in the economy Y to the total labour supply L and the stock of physical capital K. When Solow talked of physical capital he meant things like machinery, buildings, equipment, things used by labour to make products. The aggregate measurement of output is symbolised by (Y), labour (L) and capital (K). This means that Y,L and K are variables describing the whole economy. The Solow growth model tells us that in the long term, the development of a closed economy will remain at a steady state, where there is no more growth. In figure 2, the economy has settled down in point E. Here, the fraction of an average worker output that is being saved, equals the average required investment to account for the depreciation and decay. This being achieved with k1 amount of capital per worker, the economy produces an output of y1 per worker, the economy produces an output of y1 per worker. A sudden fall in the household saving ratio to s* s leads to negative net investments F minus E: workers only save a fraction s* of still the same y1, and therefore there is not enough being saved in the economy to be able to finance the decay of the capital stock at k1. As the level k1 cannot be retained by the average worker which is (negative net investments), the output per worker y has to start to decrease. In a dynamic process, the economy will move along the curve y=f(k), that means the amount of output per worker y will decrease, until it settles at a new steady state, where the net invstements equal zero. This being achieved at point E*, the resulting capital intensity is k*, with which an output of y* can be produced with y* being smaller than y1. In other words, a fall in the household ratio leads to a decrease of the amount of capital stock, a closed economy is able to to retain in the long term. The decay in the existing capital stock cannot anymore be completely replaced by investments, as there is not enough money being saved in the economy due to the fall in the household saving ratio. These resulting negative net investments will force the economy to decrease its output to the level y*. Only here, the amount being saved in the economy can again replace the complete decaying capital stock, which means the economy settles at a new long term equilibrium, a new steady state. The fall in the household saving ratio has therefore reduced the productivity of the average worker in the economy. PART B How far do models of corporation and bargaining alter our understanding of the potential for corporation between states. In this essay, I will focus myself on two models of cooperation and bargaining. The first model is called realism and its thrust is to say that the international political systems as a whole is anarchic in so far as there is no world government but what exists are multiple competing sovereigns. In terms of cooperation and bargaining between states realism poses real challenges to interdependence and specialisation. The second model is called liberalism and like realism it begins by acknowledging that the system is of course anarchic but it goes a bit further to argue that the interests that states seek to pursue in conditions of anarchy are shaped very much by the nature of the society, domestic, and transnational over which they seek to rule and particularly liberals stress the role of dominant powerful groups within society in shaping the nature of the national interests and this is clearly illustrated in a story about the development of India`s national interest in chapter 6. The fundamental difference between the two models is that liberalism says it is not just anarchy plus the distribution of power, it`s anarchy, and the distribution of power plus interdependence. The prospects for cooperation between states under conditions of both anarchy and interdependence bring to fore three aspects of the game. The first, the game is positive-sum when states are concerned purely with their absolute gains but the chance for bargaining and cooperation to mutual advantage are real and if the positive-sum is changed negatively it results in zero-sum games in which neither will be prepared to move from the original position hence blocking cooperation. You read "Explain How the Solow Growth Model Would Analyse the Effects of a Fall in the Household Saving Ratio" in category "Papers" The third is when states care about both their absolute gains and their relative positions giving us an indeterminate outcome and it very much depends on how the nations weigh the one against the other. In answering the question topic therefore, I am diving into a web of complexity. The realists`philosophical thrust claims that in an anarchic system, what then differentiates states are rather their capabilities as compared to their functions. In short it is the power of states, not their common purposes (survival), that differentiates one international political system from another (Bromley, 2004 p113) In the Realist mode therefore, the state will seek to avoid as necessary as possible forms of interdependence that create vulnerability in relation to issues of security, so they will avoid all forms of subordination with relation to other states in terms of power, since the superior power of some may also threaten the security of the weak. An example in our world today could be United States with the killing of Osama Bin Laden, where the US Navy SEALS are accused of transgression and trespassing into Pakistan without sovereign rights. In just some few words one could say that the international political systems between and among states according to realists comprise an anarchy of similar, competing political authorities in which each strives to maintain or improve its relative power base. Mexico epitomises this concept in the 1910 revolution and the subsequent creation of the PRI in 1929 which fostered a strong nationalistic ideology geared toward maintaining the independence of the country from foreign economic and political influences. Having outlined in short the essence of realist philosophy, there is need therefore, to ask what implications does this realist thinking have on cooperation and bargaining between states? The realist thinking has very essential implications in the fact that cooperation between states have to be severely limited even with big organisations like WTO because what should be avoided at all costs are dependencies. Even if there are benefits that accrue from cooperation with another state, you simply cannot depend on another country since this can create vulnerabilities lets say in cases of diplomatic fallout or cases of war. Another recent example is the treacherous diplomatic fallout between United Kingdom and Malawi with consequences on bilateral relations and especially the impact it will have on a largely dependent country Malawi. That limits considerably the scope for cooperation. According to Huysmans the other element that restrict cooperation between states, or even regional blocks in this case, sometimes like the European Union, â€Å"they are not calculating primarily their benefits from cooperation in terms of what they would gain in comparison to their major competitors, because what matters is not how much richer I become as a state, what matters is how much richer I become as a state compared to you, because then I`m more powerful, can translate to military power, economic power and so on† (Huysmans, Audio CD, 2010) In short state actors have to guarantee their own self-preservation, that is to say individuals in a state of nature or states in an anarchic international system will not willingly cooperate if the result is an increase in vulnerabilities and/ or decrease in relative power. Paul Hirst, a sociologist and political theorist served a blow to to realists`arguments by going against the view that sovereign control of territory is forged purely internally by arguing that states need to interact in the anarchic realm of international politics with other states. The achievement of sovereignty therefore, is at least partly the product of agreements between states in the form of recognition of each others`sovereign rights (Bromley 2004, p120) In this case therefore one dependents on the other. This then is the best chance to bring into play liberalism which argues that what we need to look at is the way in which the different national interests of states, that are shaped by the societies over which they rule, are configured together when put together at an international system. What we have are states all interacting with one another, all chasing national interests, as defined by their dominant groups, and those interests configure in different ways sometimes states interests are conflictual, sometimes cooperative and at some points mutually beneficial. Trade liberalisation is an example where arguably, the interests of states that are mutually engaging in trade liberalisation are not in conflict. They can both benefit from trade. States may come to view their position in relation to the others in a much more absolute terms and as a consequence of that, with full understanding of the fact that the structure of international system is interdependent as well as anarchic, enduring cooperation is at least a possibility. The states according to Bromley face an environment of what is called â€Å"strategic inter-dependence† to mean the strategies that one can champion are conditioned by their anticipation of the strategies that others will pursue (Bromley CD 2010). Unlike, the realists, the assumption is that when states`interests interact internationally, it is not always the case that states will focus on their position or be worried about dependence, and the argument pursued is that security is only one value among others, that security will be balanced alongside other considerations like economic welfare, promotion of cultural values, or whatever. In this regard Mexico is a perfect example, in so far as Mexico joined NAFTA, not worrying so much about its position vis-a-vis its dominant neighbour, the United States but increasingly focusing on the absolute gains that Mexico might make through those policies. Chapter 9, says states sometimes interact in positive-sum ways, meaning when they interact they both gain from cooperation and bargaining, sometimes they interact in ways that are zero-sum; if I gain you lose or otherwise it is negative-sum in which both sides lose. The realists model that Jef outlines seems to advocate or assume that all cooperation because they are relative ains, are zero-sum; if I gain you lose but according to liberal thinking there are situations when it is a win-win situation (Bromley CD 2010) The Liberal model also argues that there are many situations where mutual dependence does not imply vulnerability vis-a-vis security or even worry about their relative position vis-a-vis other states and an example could be that as a country, we can come to define our national interest in terms, not of how we are progressing vis-a-vis another country but how we are coping vis-a-vis last year, focused only on our growth rate. The core claim of liberal model is that once you recognise the strategic nature of interdependence and once you recognise that the national interest is socially shaped by society and not just deriving from your position in the state system, then the possibilities of cooperation are far much greater. Concluding remarks draws three general conclusions, the game is positive-sum if states are geared solely with their absolute gains, there is chance for co-operative bargaining to mutual advantage. Anarchy is no danger to cooperation in this world. Secondly, if states evaluate their positions purely in relation to others, then all games even positive-sum ones are turned to zero-sum ones where neither will be prepared to move away from the original thereby blocking cooperation as was seen between the superpowers during the Cold War. Thirdly, when states care about their absolute gains and their relative positions, the outcome is indeterminate and depends on how they weigh the one against the other. If relative considerations do not weigh too heavily in their calculations, states may still find themselves in a positive-sum game.

Censorship News Essay Example For Students

Censorship News Essay The freedom to read is essential to the democratic way of life (Censorship News 1996). Today our freedom is under attack. Private groups such as mothers and public authorities everywhere are working to remove both books and periodicals from sale, to exclude certain books from public schools, to censor and silence magazines and newspapers, and to limit controversial books from the general public. The suppression of reading materials is suppression of creative thoughts. Books are not the only one that is being suppressed by pressure to the political and social systems. They are also being brought against the educational system, radios, internet, television and against the Theater arts. However or whenever these attacks occur, they usually fall at least in one of these categories. Language Sex Drugs Society and Race Inappropriate Adolescent Behavior What is Obscenity? Clearly something hard to discuss. Obscenity is difficult to discuss honestly. Point being, what makes a thing obscene? is it something too vague to be defined. Its an elusive term we use, but cant explain. Different people often see things differently. Some see obscenity in nude pictures, statues, paintings, etc. While others find less obscenity in those things. All the same, obscene isnt the same as wrong or bad . Clearly obscenity is not identical with evil. It only covers a single segment of it. But what is that segment? A look at the words obscenity and pornography suggest that it is that its a segment that didnt worry people very much until recently. Though censorship was known in the English law quite early, it wasnt for obscenity but for heresy and sedition. David Jenkins, Undue exploitation f sex is what criminal law in Canada prohibits ( p21) . That is how criminal law defines obscenity. It doesnt differentiate between ordinary obscenity and hard-core pornography. Written by the Law reform, the first denoting the ordinary girlie and guy magazines, Literature and so on that deals with rape, bestiality, and so on People tend far more to hard-core pornography (Collins p25). Another distinction unfortunately overlooked by our criminal law is the distinction between isolated instances of obscenity and the products of vast commercial enterprise. There has been an increasing trend owards childrens literature that reflects a more realistic approach of the life both fiction and non-fiction, with subjects that include sex, homosexuality, divorce, child abuse, drugs, violence, etc. And they are these realistic books that have people outraged. In school libraries, the most frequent complains come from parents who dont have nothing better to do about the schools selections. And in the public libraries, parents were the ones again the single greatest source of challenges to materials. The world is filled with obscene things. And it would seem that those parents are ust trying to protect their children from outside world. But does it really help? These days, the average elementary school student knows many things (Collins p27). They are influence by a wide range of sources, from television , Internet and other forms of media, their environment at home and school, their personality and their backgrounds. Why they read does not necessarily mean that they will follow. Literature is a valued source of knowledge for these children, and should not be held back. So rather than applying full censorship, it should be made an age-related censorship, even hough I dont believe in censorship but think that there should be a limit for pre adolescent children. Many of the complaints that were issued were of the immaturity of the readers. And younger children should be prevented from browsing material intended for an older age group.

These types of explicit sex and literature truly have no meaning. They degrade the human race by increasing physical, mental and sexual abuse against women, animals, and sometimes against men. The inhuman treatment should not be shown to prevent other potential people from experimenting these acts. Ordinary obscenity should be censored closely, but with an objective view. They may also cause an increase in the violence against women, so they must be reduced and kept out of reach of the immature readers. To make a tree grow correctly, you must start caring from the beginning. You must not block its nutrients, water, nor sunlight, but allow it to move around a bit ( Jenkins p29). We have a governing social system that mainly frowns upon the violence against women and Children. There should indeed be access to most types of literature, but in varying degrees to freedom, determined not by censorship, but by controlled access. Parents are trying to protect their children from the harsh realities of life, but are they really helping, or hindering.

Differences between the America and Chinese Education Systems

Introduction With the ever-increasing need for an educated society that can survive in the present competitive world, most nations have started to appreciate the need of a well educated citizenry. In addition, because education is the greatest promoter of culture, every country’s education system is a representation of its history and cultural values.Advertising We will write a custom research paper sample on Differences between the America and Chinese Education Systems specifically for you for only $16.05 $11/page Learn More Therefore, although there may exist some similarities between different country’s education systems, each country’s education system has some unique features that give that country an added advantage in terms of developing its social, cultural, political, and economic systems. These like differences are evident in the Chinese and American education systems, because of the varying importance given to different as pects of education by these two nations. China’s education system primary emphasizes on the input and accumulation of skills, promotion of learners’ appreciation of knowledge and the respect those in power. Contrary to this, the American education system primarily emphasizes on imparting in learners practical skills meant to help learners to question knowledge and authority (Si-jing 1). Considering this, the American education system emphasizes not only on imparting basic skills such as reading and writing, but also emphasizes on the physical and mental wellbeing of learners, whereas the Chinese education system mainly focuses less on creativity, but emphasizes the need to impart in the necessary survival skills. Differences between the U.S. and China’s Education Comparison of the social environment and culture tradition between China and America As compared to China, the U.S is an open society that has abandoned most of its traditional practices to adopt a new era of education reforms to accommodate the diverse nature of cultures that comprise its citizenry. In addition, because the American economy lays a strong emphasis on the significance of practical skills, its education system appreciates the significance of independence in thinking and creativity. Therefore, the American education system generally prepares individuals to be â€Å"social beings† who must endeavor to discover and put their talents into use in order to get material wealth. In contrast to this, the Chinese empire is a historically rich economy that appreciates very much its cultural traditions; hence, the rigorous nature of its education curriculum that lays a strong emphasis on morals and attainment of education that is relevant to its needs. As compared to the U.S., the stress of living in China is bigger, because most jobs dictates that an individual must go to college and get the relevant education, failure of which can lead to a miserable life.Advertising Looking for research paper on education?

Get your first paper with 15% OFF Learn More On the other hand, the Chinese education system strongly emphasizes on laying a strong education foundation that is characterized by less thought and extra learning. Different to this, because of the significance of creativity in America, its education appreciates the need for more thinking and less forma learning, because of the readiness of the American society to adopt new concepts, so long as they have a positive impact on its citizenry (Rybak 1). Differences between China and U.S’s Education Curriculum Both in the U.S. and China learners must o through a total of twelve years elementary and high school that are broken into six years of elementary school, two years of middle school (in the U.S. it is called junior high), an finally three years of senior high school. Although this similarity exists, China’s system is more rigid, because of the nature of its education principles; a case that is different in the U.S., where learners have the freedom of selecting lessons that that they should attend. In addition, unlike in the U.S. where wearing of school uniform depends on a school’s policies hence, not a must, in China wearing of special attires to school is compulsory. Further, the Chinese education system is more competitive, because of the numerous and tough examinations that learners are supposed to take before proceeding to another level of learning. As results of this, learners in China always spend their entire school life preparing for exams; exams which in most cases are very tough as compared with the SATs taken in the U.S (Guihong 1). Another disparity between U.S. and China’s education is in how students join their desired colleges. Although in both of these countries learners have to take some special test, whose results are used as the primary method of determining the type of college that one will join, in China these results are more important as they are also the primary determinant of the type of major that a learner will take. In China learners are supposed to write a list of majors that they want to pursue, after which depending on their exam results their tutors will pick for them a major that fits them. The scenario is different in America as learners are supposed to make applications to their preferred colleges, after which they will have to wait for feedbacks from these colleges, before making any decision on the type of major to pursue. Moreover, as compared to the U.S. where entry into a major and changing from one major to another is not a big struggle, in China getting into a preferred program is a very competitive endeavor and in most cases it is impossible to change from one major to another (Rybak 1).Advertising We will write a custom research paper sample on Differences between the America and Chinese Education Systems specifically for you for only $16.05 $11/page Learn More In addition to these differences, because of the significance the U.S. places on the need for practical skills, learners in the U.S. spend a lot of time in labs, something that is a little bit different in China where rote learning and theory work is common. Although at some point learners in China practice their hands on work, most Chinese learners do not appreciate the significance of work experience before commencing their graduate studies. It is important for individuals to note that, although this is the case in most learning institutions in China, because of the realization by the Chinese government about the significance of practical experience, the Chinese government is the process of reforming its education system to accommodate the ever-changing global educational needs (Li, Paranto and Rong 3-5). Additionally, when it comes to higher education, each of these countries’s higher education is a reflection of its economic needs. The U.S. higher education is structured in way that it is supposed to respond to the ever-changing societal social, political, and economic needs. The scenario is a little bit different in China, because most of its specialty programs lack the required flexibility required for an education curriculum to be responsive to changing societal needs. Further, China’s higher education lays a strong emphasis on the significance of systematic study, as it is requirement for tutors to adhere to specific teaching programs. Although to some level teacher-learner interactions are common in this type of teaching environment, such interactions are limited as compared to most typical classes in the U.S. where it is must to give learners the required autonomy and freedom to express their ideas (Mark Para. 8-13). Conclusion In conclusion, although the American system of education shares some similarities with the Chinese one, because of the nature of varying cultures that are a ppreciated in these two nations, there exist numerous differences between two country’s systems of education. As compared with the American system of education that is flexible and accommodative, the Chinese system of education is more rigid and although to some level it aims to build learners with the desired skills needed in the competitive world, it is less practical and sensitive to changing global educational demands.

Tatoo is good - Essay Example The tattoos designs are not just restricted to anchors, skulls, and battleships but now, ways and designs have come under findings by the populace as a mean to express themselves. A tattoo that is profound into the skin is a perforate lesion, where needles come under the use to pierce into the skin of an individual and infusion of ink through that needle occurs to make some type of a design. Since the tattoos are deep-rooted into ones’ skin, this attribute of tattoos make them lifelong stay on the body. Initially, hands came under use in operating the practice of tattoo making and there was no mechanical way of doing it, but with the advancement in technology, the tattoo artist makes use of a machine (electric gadget) to make the tattoo. In some remote areas of the world, the practice of making tattoos is still manual. The tattoo making is not a new art, as it has been in practice from scores of generations across the globe. In some parts of the world despite of being popular, is it considered as a symbol of religious and divine dedication, awards or medals of gallantry, sexual attraction or expression of love, lucky or good luck charm, security, and as the marks of outsider, slaves and guilty. Different religions and cultures have different concepts, meaning, and impact of the tattoos and its symbols. In recent years, moreover people make tattoos to express their feeling to their loved ones, whether it be mother, father, siblings, children, or someone special. Even some individuals make tattoos for cosmetic, monument, and magical grounds to get themselves coupled or recognized with a particular social or ethnic group. Tattoo is not a new concept and has been in existence for more than five thousand years. Tattoo is an unintentional invention by a person who got a small injury, and rubbed that cut with the hands full of dirt with fire ashes.

The history of tatt oos reveals the fact that tattoos has been in subsistence since the time of the civilization and has been present in many cultures around the world.

WHAT ASSUMPTIONS DOES THE CONCEPT OF TRANSFER MAKE ABOUT THE Essay

WHAT ASSUMPTIONS DOES THE CONCEPT OF TRANSFER MAKE ABOUT THE DEVELOPMENT OF AND THE APPLICATION OF KNOWLEDGE AND SKILLS IN AND BETWEEN EDUCATION AND WORKPLACE - Essay Example llenge for vocational educational programmes is therefore to provide effective support to students so that they are able to effectively make the transition from school to the workplace. This assignment deals with the concept of transfer of knowledge and skills from school to the workplace and how effectively an understanding of the transfer process helps to evaluate the degree to which this is being achieved. Existing vocational education curricula are unable to effectively bring about the transfer of students from the context of the school to the workplace. What are the reasons for this and what is the role of knowledge and skills acquisition in the transfer process? These are the questions I will attempt to answer in this essay. This first section discusses the concept of knowledge itself, in order to provide a basis for assessing how far the transfer of such knowledge is supported by vocational education. It will examine the different kinds of knowledge as well as skills and the importance of possessing them in the workplace. Knowledge may be tacit, explicit or situated. While situated knowledge is relevant within a particular work context and may be taught through workplace training and the use of handbooks and manuals tacit knowledge is group knowledge that develops within a specific cultural context and may be more difficult to replicate (Guile and Young 2003). Guile ([2002] citing Drucker [1993]) mentions that some authors view knowledge as an embrained phenomenon, for example, it exists either as a product of someone’s mental abilities or as data that may be found on websites, therefore innovation in such an instance will involve transfer of skill and expertise from one section of an organization to another. Other authors such as Noneka and Takeuchi ([1995] as cited by Guile [2002]) have suggested that the development of innovation in business is dependent upon the extent to which the tacit knowledge possessed by the firm is successfully exploited,

International Trade Laws Essay Example | Topics and Well Written Essays - 1250 words

International Trade Laws - Essay Example This works for the higher competitive advantage of the national companies, and thus 'closing eyes' on the illegal actions foreign companies take abroad, as well as trying to sue them for the refund of the damages which national companies pay abroad, and which is often resolved for the benefit of the national company, is a means of fighting competition through the means and methods which are legal only on the surface. 'Competition law embodies an inherent conflict while protecting local consumers from monopolies, cartels and oligopolies - it ignores the very same practices when directed at foreign consumers'. (Francis, 1995) For example, even GATT /WTO rules allow the existence of the foreign trade cartels, and if the same actions would be considered to be illegal within the country, these actions are seen as proper and legal at the international level. (Mathis, 2002) It was interesting to note, that one of the literary sources recommends adoption of the claw back provisions for the poor countries, which would want to develop their export markets. These claw back provisions would allow local courts to refund any penalty payment put on the local company by a foreign entity for the violation of trade policies and using unfair methods of international trade. ... Let's have a closer look at the GATT International Antitrust Code, which has created the four main principles, violated through the use of claw back provisions. - National laws should be applied to solve international competition problems; - Parties, regardless of origin, should be treated as locals; - A minimum standard for national antitrust rules should be set (stricter measures would be welcome); and - The establishment of an international authority to settle disputes between parties over antitrust issues. (Tarullo, 2002) The use of claw back provision if the violation of the first noted principle - they are not crated in accordance with the international laws and they don not foster creation of the laws which would support competition on the international level. Moreover, 'parties, regardless origin, should be treated as locals'; however claw back provisions are clear examples of the absolutely opposite actions of the parties. Claw back provisions are often depicted as the best means of protecting the parties from the improper judicial treatment in the foreign country; however fighting illegal actions and unfair competition is possible only through the adoption and use of such fines and damage payments for the benefit of the party the rights of which were violated. According to the Havana Charter 1947, there is a list of actions which are supposed to be illegal and represent the moves of the unfair competition; among these actions are discriminating particular enterprises, excluding enterprises from a specific territorial market, etc. Claw back provisions, on the contrary give local (national) companies legal basis for unfair competition' actions in the foreign country through understanding that in case they are sued, their country of

Prevention of disease

Prevention of disease Introduction: Prevention of any disease causing agent at livestock farm by managemental mechanisms and operations is known as biosecurity.Due to increased incidence of many foreign and emerging diseases such as FMD and Avian Influenza has made it of major concern. Biosecurity is basic phenomena in disease prevention at farm. there are many factors that contribute towards disease at livestock farm .Their list includes Farm visitors Veterinarians themselves Regulatory personnel Dead stock collectors Friends all of these should understand the importance of biosecurity. if any one of these does not aware of biosecurity he will ultimately contribute to make himself and animal susceptible to disease. May be it is possible that a person carrying infection visit multiple farms in one day and may effect other farms .As a result of which the disease can spread in whole country. So today there is need to develop certain mechanisms and operations to minimize the chances of disease occurance .and this can be done with the help of qualified and experiences staff at farm which include farm manager ,farm supervisors, nutrition and extension specialists, Because various problems in practical implementation for prevention of disease are due to the fact that majority of livestock farms are managed by illiterate and ignorant persons who ignore the basic principles of biosecurity and sanitation .improper sanitation provides the ideal environment to bacteria, parasites ,viruses and fungi and provide shelter to germs. Proper sanitation identify the causes of all preventable diseases and make all those causes ineffective to spread diseases .By this animal can live in the favorable conditions of li fe with provision of clean water, good ventilation and well sanitize sheds. There are four basic steps in prevention of disease. Proper vaccination Detection of disease Removal of intermediate hosts Control meseaure for infectious disease Disease results from the intervention of infectious agent in the farm in outs and farm outputs. Farm inputs includes the health of animal , housing hygiene ,feed and water hygiene .farm out puts includes the farm visitors, wild life and visiting vehicles .Farm input and outputs both should be controlled for prevention of disease. Whenever there is breakage in biosecurity process the infectious agent infects animal which sheds agent in environment (foods, water, housing) and ultimately make animal susceptible to disease .It is shown in following diagram, Biosecurity increases the death rate of germs, reducing chance of infection . Bioseurity not only prevent disease in this way but also enhances the prevention by sanitation of farm premises ,by maintaining close herd and by killing the natural and mechanical carrier of disease .Bioseurity helps us to prevent the disease causing agents inside the farm and stops them to enter at farm but one thing keep in mind that close observation and biosecurity measures should be adopted at constant basis. Biosecurity plan For prevention of disease an effective Biosecurity plan and its accurate implementation is needed at farm. Biosecurity plan limits the chances of disease occurance. It prevents pathogens from entering through different routes of transmission. Biosecurity can be broken through any of following routes shown in diagram below. A biosecurity plan consists of isolation, traffic control and sanitation. At first isolate animal according to age and production. Isolate sick animals for at least one month and they should be separately feeded. They should be properly vaccinated according to appropriate vaccination programme to produce immunity against infectious diseases. Basic purpose of isolation is to control the visitors minimize contact between disease and healthy animals. New animals should pass through process of quarantine remember that new animal are greatest risk to biosecurity. Secondly control the visitors and vehicles that routinely visit your farm .Only concerned visitors should be allowed to visit farm. They should be properly dressed up wearing coveralls and gum boots. Vehicles should be properly cleaned and disinfected before entrance. Vehicles should be free of any unwanted material that can cause disease. Adequate fencing should be provided for protection of animals against wild life and neighboring herds. Lastly ensure sanitation at livestock farm. Sanitation minimizes the effects of infectious agents by adapting hygienic practices and maintaining health status of animal. Provide proper lightning and ventilation in animal sheds. Clean bedding should also provided .Adopt all the sanitary conditions to ensure a healthy calf at birth. Good hygienic conditions for young animal are important in both safeguarding health and future profit .Sanitation should be carried out in all aspects including farm equipments, farm employee, farm visiting vehicles. Milking should be done in hygienic environment .both milking man and milk collecting utensils should be clean. Teats should be dipped regularly and do not handle udder with dry hand because it will lead to chapping of udder. Disinfection is process to kill all bacteria and parasites with the help of specific compounds. Disinfection should be thoroughly carried out. Before disinfection a thorough cleaning of building is necessary to facilitate disinfection. Instruments (hoof knives, clippers, dehorners) are main source of cross contamination so, should be disinfected before and after use. There should be separate instruments that are to be used on disease and healthy animals. As the infectious agents are very small and they become indefinite in dust, cracks and crevices and surfaces of buildings .so, disinfection should be done with extreme care and attention to kill all the life threatening bacterial, parasitic, fungal and viral agents. At a limited area disinfectant can be applied with help of brush while for a large area disinfectant can be applied by spraying on that area. Some disinfectants are extremely irritating to eyes and skin so person applying disinfectant should wear gloves to protect skin an d goggles to protect eyes. Disinfectants commonly available in market are pyodine (iodine), parachlorometoxylenol (dettole), methylated spirit, and carbolic acid or phenol. They are available in low cost. Some insecticides are also available that are applied externally to kill ticks, mites and fleas on animal body. These include coal tar, petroleum and nicotine. Employee clothing should be continuously washed with detergents.. In addition to disinfectant the sanitizer can also increase death rate of infectious agents and decrease their population. A sanitizer kills about 99.9 percent of all bacteria, fungi and viruses. Disinfectants are classified into three types sunlight ,heat(hot air, steam, fire) and chemical disinfectants .Chemical disinfectants are further classified into three types compounds (pot.permnganate), alkalies(pot.hydrooxide,limesoln) and acids(boric acids, carbolic acids).classification of disinfectants is shown below in diagram Conclusion Biosecurity is an important step towards the prevention of disease before its occurance as prevention is better than cure .Biosecurity play a significant role in production of healthy and profitable livestock.

Diary of Mrs. Amelia Stewart Knight :: essays research papers

Response on â€Å" Diary of Mrs. Amelia Stewart Knight† When I finished this article I started to realize that the life of pioneers was not just one big adventure, but they had to face some really difficult problems like dangerous river crossing, bad weather, different kinds of accidents and diseases along the way without any chance for medical treatment. But first of all I had make a research to answer one question before all the problems along the way. It is how much did pioneers traveling west needed and how long did they have to safe money to be able to support their trip. It took roughly $800-$1,000 to obtain a proper outfit (wagon, food, clothing, etc.) and enough supplies to live a whole year without planting or harvesting a crop. Some families saved for three to five years before being able to begin their trip to west. From mine point of view they had to be very patient and live more or less in poverty to be able to save such a big amount of money. That means that most of people had a lot of problems even before they started they â€Å"trip† to west. Another great surprise for me was that most people walked and made the entire 2,000-mile journey on foot because most emigrants grossly overloaded their wagons and that is why only few could ride inside the wagons. Most of emigrants who could ride inside were children and women. To ride in a wagon sounds really better than walking all 2000 mile on foot, but another problem which they had to face was that the emigrant wagons didn't have any safety features. If someone fell under the massive wagon wheels, death was instant. Many lost their lives this way and as I mentioned above most often, the victims were children. Farther more the river crossings, which were necessary to get to their point, were a constant source of distress for all members of the group. Hundreds drowned trying to get wagons, cattle and another stuff to the other shore. Perhaps the biggest problem on the Trail was a deadly disease with no cure at that time, called cholera. This disease was a really big threat, not only for an individual, but also for the whole group. First of all it’s very contagious and secondly the sick person would slow down the whole caravan. Sometimes they received a proper burial, but often, the sick would be abandoned, in their beds, on the side of the trail and die alone.

Maria Reynolds and the First U.S. Political Sex Scandal

Maria Reynolds and the First U.S. Political Sex Scandal Maria Reynolds is best known for her role in the United States first political sex scandal. As the mistress of Alexander Hamilton, Maria was the subject of much gossip and speculation, and she ultimately found herself embroiled in a blackmail scheme. Fast Facts: Maria Reynolds Known For: Mistress of Alexander Hamilton, an affair that led to the publication of the Reynolds Pamphlet and the United States first sex scandalBorn: March 30, 1768 in New York, New YorkParents: Richard Lewis, Susanna Van Der BurghSpouse(s): James Reynolds, Jacob Clingman, Dr. Mathew (first name unknown)Died: March 25, 1828 in Philadelphia, Pennsylvania Early Life Maria was born in New York City to middle-class parents. Not much is known about her early life. Her father, Richard Lewis, was a merchant and itinerant laborer, and her mother Susanna Van Der Burgh had been married once before. (Of note, Susanna’s sixth great-grandson would become President George W. Bush.) Although Maria wasn’t formally educated,  her letters to Hamilton show that she was marginally literate. In 1783, when Maria was fifteen, her parents consented to her marriage to James Reynolds, several years her senior, and two years later she gave birth to their daughter, Susan. The couple moved from New York to Philadelphia at some point between 1785 and 1791. James had served during the Revolutionary War as a commissary agent, alongside his father, David. In addition, he had a pattern of filing claims with the government for damages and losses accrued during the war. In one letter to George Washington, dated 1789, James Reynolds asked for a land grant. The Hamilton Affair During the summer of 1791, Maria, then twenty-three years old, approached Hamilton in Philadelphia. She asked for help, saying James had abused and then abandoned her for another woman. She begged Hamilton, who was thirty-four and married, for financial assistance so that she could return to New York with her daughter. Hamilton agreed to deliver money to her, and promised to stop by Maria’s boarding house to drop it off. Once Hamilton arrived at Maria’s Philadelphia lodgings, she led him to her bedroom, and the affair began. The affair continued for the summer and fall of that year, while Hamilton’s wife and son were visiting family in upstate New York. At some point, Maria informed Hamilton that James sought a reconciliation, to which she had agreed, although she had no intention of ending the affair. She then arranged for Hamilton to meet James, who wanted a position in the Treasury Department. Hamilton refused, and indicated that he no longer wanted to be involved with Maria, at which point she wrote again, saying her husband had found out about their relationship. Soon, Reynolds himself was sending angry letters to Hamilton, demanding money. In December 1791, Hamilton paid Reynolds $1,000 - a staggering sum at that time - and ended the affair with Maria. However, a month later, Reynolds surfaced again, and this time invited Hamilton to renew his romantic attentions towards Maria; she also encouraged Hamilton’s visits. Each time, Hamilton sent Reynolds money. This continued until June 1792, when Reynolds was arrested and charged with forgery and fraudulently purchasing pensions from Revolutionary War veterans. From jail, Reynolds continued to write Hamilton, who refused to send the couple any further payments. The Scandal Once Maria and James Reynolds realized there was to be no further income from Hamilton, it wasn’t long before whispers of scandal got back to Congress. Reynolds hinted at public misconduct, promising to testify against Hamilton, but instead vanished after being released from jail. By then, though, the damage was done, and the truth about the affair with Maria was the talk of the town. Worried that accusations of financial misdeeds could destroy his political hopes, Hamilton decided to come clean about the affair. In 1797, he wrote what would become known as the Reynolds Pamphlet, in which he detailed the relationship with Maria and the blackmail by her husband. He maintained that his wrongdoing was adultery, not financial malfeasance: â€Å"My real crime is an amorous connection with his wife, for a considerable time with his privity and connivance, if not originally brought on by a combination between the husband and wife with the design to extort money from me.† Once the pamphlet was released, Maria became a social pariah. She had divorced Reynolds in absentia in 1793, and remarried; her second husband was a man named Jacob Clingman, who was implicated along with Reynolds in the pension speculation scheme. To escape further public humiliation, Maria and Clingman left for England in late 1797. Later Years There are no details about Maria’s life in England, but when she returned to the United States years later, it was without Clingman. It is unknown whether he died, she divorced him, or she simply left. Regardless, she was using the name Maria Clement for a time, and worked as a housekeeper to a physician named Dr. Mathew, whom she later married. Her daughter Susan came to live with them, and enjoyed some degree of social status with her mother’s new marriage. In her later years, Maria cultivated respectability and found solace in religion. She died in 1828.

Medeas fatal flaw essays

Medeas fatal flaw essays Every highly tragic and dramatic figure has a fatal flaw that leads to his or her downfall. The character of Medea fits into this category perfectly. Excessive passion is what leads Medea to her destruction. Her love for Jason, her selfishness, and her rage are all factors of Medea's harmartia. First, the strongest factor contributing to Medea's fatal flaw is her love for Jason. During Jason's quest of searching for the Golden Fleece and meets the Princess of Colchis, Medea falls madly in love with Jason and runs off to lolcos with him. Medea and Jason get married and have two children. Medea's excessive love for Jason started showing when she killed his uncle, who was the king of lolcos at the time, so that Jason could take over the throne and rule. But his uncle's murder resulted negatively for Medea and Jason. They were forced to flee from lolcos to the kingdom of Corinth. Once in Corinth, Jason meets the king of Corinth's daughter. He leaves Medea and their two children and marries the princess. Because Medea is madly in love with Jason, Medea is crushed to find out that Jason has left her. Medea explains to the women of Corinth that, "It has crushed my heart. Life has no pleasure left, dear friends. I want to die. Jason was my whole life; he knows that wel l" (24). Therefore, Medea becomes outraged and over powered with excessive passion. Secondly, Medea's selfishness provides power to her fatal flaw. Medea's selfishness is displayed through the act of killing her own two sons. Medea understands that the slaying of her children will make Jason miserable. During this time, the chorus recognizes her self-worship and states, "O miserable mother, to destroy your own increase, murder the babes of your body! Stone and iron are you, as you resolved to be" (56). Medea does not stop to think what pain she may cause to herself by murdering them. She is only concerned about her happiness ...

Capitol Budgeting Long Term Financing Assignment

Capitol Budgeting Long Term Financing - Assignment Example Capital assets receive attention because they commit a firm for long term. These capital assets are commitment of over a year and sometimes for decades for instance, real estate. Economically, the resources being scarce and competitive in nature, there would be wrong allocation of such resources at the wrong time or on a non rewording asset. Assets acquisition analysis According to (Baker, & Powell, 2005) any company will invest finance for the sake of gaining a return which is useful for four focal reasons: 1. To recompense the shareholders or owners of the enterprise for staking their money and by sacrificing their current purchasing power for the sake of current and future cash flow 2. To reward lenders by paying them regular return on their money borrowed in the form of interest and principal repayment as and when it falls due. 3. To be able to plough back retain part of their earnings for the purpose which facilitates not only the companies’ short term growth and long ter m growth but also has the implication of increasing the size of the company in terms of sales, in assets as well as shareholders wealth. 4. To increase the share prices and thus the credibility and goodwill of the company and its capability to raise further finance. Such return is necessary to keep the company’s operations moving straightforwardly and efficiently thus allowing the above objective to be accomplished. A financial manager and decision makers must present investment policies which will be concerned with how efficiently the company’s funds are invested because it is from such investment that the company will survive. The investments are important because: They influence company’s size, Influence growth Influence company’s risks In addition, to this investment decision making process which is also known as capital budgeting, involves the decision to invest the company’s current funds in viable ventures whose returns will be realized for long term periods in future. Capital budgeting as financial planning is characterized by the following: a. Decisions of this nature are long term i.e. extending beyond one year in which case they are also expected to generate returns of long term in nature. b. Investment is usually heavy (heavy capital injection) and as such has to be properly planned. c. These decisions are irreversible and any mistake may cause the company heavy losses. Importance of Investment Decisions 1) Such decisions are importance because they will influence the company’s size (fixed assets, sales, and retained earnings). 2) They increase the value of the company’s shares and thus its credibility. 3) The fact that they are irreversible means that they have to be made carefully to avoid any mistake which can lead to the failure of such investment. 4) Due to heavy capital outlay, more attention is required to avoid loss of huge sums of money which in the extreme may lead to the closure of such a company. However, these decisions are influenced by: I. Political factors – Under conditions of political uncertainty, such decisions cannot be made as it will entail an element of risk of failure of such investment. Thus political certainty has to be analyzed before such decisions are made, such factors must be taken into account such that the company forecasts the inflows and outflows within given. Limitations such as the

Freedom and emancipation of women Essay Example | Topics and Well Written Essays - 1250 words

Freedom and emancipation of women - Essay Example On the other hand, men were more flexible and could look for work and live away from homes, while still expecting to have their wives take care of their children at home. In Kate Chopin story â€Å"the story of an hour†, women are depicted as being oppressed, but repressing their feeling despite their desire for freedom. The theme of oppression of women in the society is best captured in the story of an hour where Mrs. Mallard; the main author who is depicted as having a heart trouble. This is the reason why the death of her husband is brought with gentleness (Chopin 788). This is a disease that Chopin refers to be the one of the causes of trouble facing Mrs. Ballard. In the story, the heart disease is a symbol of the pain that Chopin has to contend with, one that makes her sick and remain at home, while her husband goes to work. The interpretation of the heart diseases ties with the notion that women’s places was home and not in the industry, which was considered as a playing field for men only. This was a belief that men held during the nineteenth century, at a time when women were trying to liberate themselves from chains of having to take roles as wives at home. But as indicated in the story, the struggles of women like Mrs. Mallard bore no success as she succumbed to death because of her heart trouble. Mrs. Mallard is depicted as a young woman in the story and yet all she could do was stay at home, while the husband went to work to fend for the family. Chopin’s portrays Mrs. Mallard as a young woman who has a fair and calm face. These descriptions indicate the status of women in the society being that most of them had the potential to take over roles in the industries and other domains (Stein 54). Needless to say, the theme of oppressions seems to be overstretched on women like Mr. Mallard who have to wait at home for the husband to come home. In addition, it is clear to point that men made women hold gender roles at home advancing the theme of oppression. In what seems as a twist, Mr. Mallard later becomes happy because the death of her husband meant his freedom. In the story, Chopin describes Mrs. Mallard as having a dull stare, one that illustrates the kind of life she has gone through. The dull eyes present readers with the feeling of women have having been stagnated and withdrawn in the quest for freedom. This notion is true considering the fact that women during the 19th century continued to hold a role at home with none having the chance to take part in other facets of life. In the story, it is apparent that Mrs. Mallard is less independent in her marriage, which indicates the oppression that women were going through in their society. To a great extent, it can be argued that married women like Mrs. Mallard were less independent because of their allegiance to the will of their husbands. Historically, the women’s quest from freedom in the nineteenth century reflected the difficulty of women making sig nificant breakthroughs in a society where men were parochial. In another perspective, the dull stare reveal the routine that characterized the lives of women being that many of them stayed at home. This signifies a form of oppression that made women restricted to their homes rather than joint the social and economic life experienced by their male counterparts. To some degree, Chopin reveal that women despite being oppressed remained tied to their husbands to the chain of oppression tha

Obesity and its causes Research Paper Example | Topics and Well Written Essays - 750 words

Obesity and its causes - Research Paper Example cause of obesity is the availability of a variety of consumer snack products in the country containing trans fats and other preservatives with high levels of saturated fat. In today’s difficult economy, the costs of healthier foods are increasing due to rising prices in the global food supply chain, therefore consumers turn toward unhealthier food options due to pricing. The high availability of these foods in this competitive marketplace where variety and option is tremendous along with a more attractive price tag can be attributed as a significant cause of obesity increases in society. Furthermore, the method by which food manufacturers market their products to youths is another reason for the growing trend of childhood obesity. Less health food options, such as those made by Cadbury or Nestle, two well-known global chocolatiers, often use innovative advertisements are part of marketing to appeal to the child’s lifestyle and personal values. Finding these promotional connections leads youths to sample high-fat or high-calorie foods due to brand image or how the product is presented using colorful or imaginative characters. This is a psychological contribution to the escalation of obesity and is a product of business marketing, an industry which is â€Å"being lambasted for its all-too efficient efforts in pushing less healthy snack foods to children† (Alistair, 24). Obesity is also caused by the rising instances of quick service or fast food restaurant concepts which provide high fat foods products to consumers in a hurry. In today’s global marketplace and consumerism economy, many households have both parents working in order to sustain quality of lifestyle. This changing trend toward the hassled lifestyle drives many parents toward this convenience, fast service menu. McDonald’s, under pressure by health advocates, became the first fast food restaurant to post nutritional information on their packaging (Grant, 9). This illustrates that the fast food

Mass and Energy Balance Essay Example for Free

Mass and Energy Balance Essay Abstract The objective is to produce a proposal for a chemical process plant which will be able to produce 550,000 tonne/year ammonia using LPG as the raw material. Different processes where researched and then finally one was picked, steam reforming. This was decided to be the most viable and cost effective process using the raw materials we had available. The report explains in detail how the process works and all aspects of how the plant will work including the mass and energy balance across the plant. What is Ammonia Ammonia (NH3) is a stable compound and is used as a starting material for the manufacture of many important nitrogen compounds and can also be directly used as fertilisers. It is produced by reacting hydrogen and nitrogen. It is a colourless gas with a sharp odour. The boiling point is -33.35oC and its freezing point is -77.7oC.1 Care must be taken when handling ammonia as can cause deep burns in the skin; irritation in the eyes and nose and when inhaled can cause coughing, sore throat and headache.2 There are different methods for the manufacture of ammonia. The three main methods are steam reforming, partial oxidation and electrolysis. Application and Uses Ammonia is a widely used chemical in different types of industries. One of the main user of ammonia is the agricultural industries for fertilisers. Around 80% of ammonia produced is for fertilisers such as urea, ammonium sulphate and ammonium nitrate.3 It is also used as a building block for nitrogen containing compounds like nitric acid (HNO3). It is also used in the fibres and plastics industry for the production of acrylonitrile, melamine etc., and manufacture of explosives. Ammonia is also used in water treatment such as pH control and also in combination with chlorine to purify industrial and municipal water supplies. Less commonly uses include as a refrigerant in compression and absorption systems, manufacture of household ammonia, in the food and beverage industry 4. Figure 1: Pie chart showing the uses of Ammonia. Market Trends Globally ammonia prices have been headed up due the large demand of fertilisers that are needed in the crop production to obtain high yield6. The current selling price of ammonia in Europe goes up to $600 per tonne7. Figure 2: Shows the global demand for Ammonia (D.a.NH3- Direct application of Ammonia) As we can see from the chart the trend of ammonia demand globally is upward. It is said that the global ammonia market is to generate revenues of approx. US$102 billion in 2019. As there is continous growth in population in the developing countries the likely to cause demand for foodstuffs are to increase even further. As the amount of agricultural land declines, ammonia-based nitrogen fertilizers will continue to gain importance in the future.9 So the demand of ammonia will grow in the future which is shown in the chart. Processes There are many different processes involved in the ammonia production. The most common processes for ammonia are partial oxidation, steam reforming and electrolysis. From these 3 processes the best process route is then selected and that process would be most economical and that meetes the design brief. Partial Oxidation Partial oxidation involves the reaction of oxygen with fuel to produce hydrogen. The following equations represent the partial oxidation of ethane, propane, butane and pentane. 10 C2H6 + O2 2CO + 3H2, C3H8 + 1.5O2 3CO + 4H2, C4H10 + 2O2 4CO + 5H2, C5H12 + 2.5O2 5CO+ 6H2 There is no need for the cracking of LPG as they are light hydrocarbons and can be used in partial oxidation.11 See Partial Oxidation flow sheet (Reference 1: Partial Oxidation Flow Sheet) Hazards and Environmental Impact The main emission is carbon dioxide which is a greenhouse gas and Partial Oxidation process emits more carbon dioxide compared to Steam Methane Reforming. Carbon dioxide emissions can be reduced by recycling it and selling it to urea and nitro-phosphate plants.13 No ammonia should be present in the air but maybe because of faulty equipment and maintenance activities, some ammonia maybe released. Ammonia becomes explosive at the 16%-25% volume in air which could occur if there are any leakages in the ammonia storage facilities. It is also toxic by inhalation and pulmonary oedema can occur up to 48 hours after exposure and could be fatal.12 Nitrogen dioxide that is released is a toxic gas can be harmful when inhaled but can be avoided as can be detected because of the smell. The large amount of waste water from this process is another problem but there is a river near the Milford Haven site. Also water pollution is a concern which may occur because of the suspended and dissolved impurities. It could also affect the aquatic life. Therefore the water must be treated in a full three stage water treatment plant before disposing it. 13 The disadvantage of partial oxidation is that the capital costs are higher for partial oxidation compared to any other process. It is estimated to be  £100-120 million for an annual production of 7.7 million GJ while for SR it will only be  £70 million. 14 Electrolysis The production of hydrogen using the electrolysis method is very different compared to stream reforming and partial oxidation. Electrolysis produces hydrogen by splitting water into hydrogen and oxygen using volts of current to separate the hydrogen to one electrode and oxygen at the other in a cell. Oxygen is the by-product in the process of producing ammonia which is valuable because it can be used in other chemical processes or sold to other companies for profit. In electrolysis there is no CO2 produced therefore there is no pollution. Standard electrolytic ammonia production energy consumption historically has been about 12 megawatt-hour. The fuel cost alone of making ammonia is $600 metric ton, and including capital and operating expenses that metric ton of ammonia cost about $800 to make. Compare electrolytic and using uses of natural gas as raw material the economically, for the past 100 years the cost of natural gas has not been higher than $1 and the fuel cost for a metric ton of ammonia from natural gas has been $30-$40. Figure [ 3 ]: Ammonia Manufacturing Process Figure 3: Ammonia Manufacturing Process Steam Reforming Gas purification Syngas of a mixture of hydrogen, carbon monoxide, carbon dioxide and water can be broken down in to individual components and further cleansed through purification. The syngas will enter a shift reformer, which breaks down the carbon monoxide in to hydrogen and carbon dioxide using steam (H2O). Carbon dioxide is much more environmentally friendly than CO and can either be released in to the atmosphere or used in other steam reforming processes in the future. Desulphurisation Sulphur is a problem when carrying out steam reforming as it acts as a poison for the catalysts involved. It is important that this is removed prior to the syngas entering the system. The process is carried out in the presence of a catalyst, which is usually nickel. This nickel acts as an absorber for the sulphur, and so several catalyst-filled tubes within the system with a large internal surface area will allow the sulphur to collect to be disposed of suitably. The Process Hydrocarbons usually contain sulphur which needs to be removed. The purification section is the first bed of the whole steam reforming process. Feed is passed through tubes containing zinc oxide. The sulphur in the feed reacts with the zinc oxide to produce zinc sulphide. This is to ensure that the feed travelling to the steam reformer does not poison the catalysts in this section in any way. The catalysts used in the steam reforming process are nickel-based. These are easily poisoned by sulphur species. The purified feed is mixed with steam and then is passed to the primary reformer, which involves a nickel-based catalyst where the steam reforming process is carried out. Once the hydrocarbon is cleansed of sulphur, the reforming process can begin. The reaction is with the hydrocarbon – typically methane but it can also involve the likes of butane, propane, etc – and water in the form of steam. The reaction for methane (CH4) is shown below. CH4 + H2O 3H2 + COΔH = +251kJmol-1 C3H8 + 6H2O 3CO2 + 10H2 C2H6 + 4H2O 2CO2 + 7H2 C4H10 + 8H2O 4CO2 + 7H2 C5H12 + 10H2O 5CO2 + 16H2 Reactions for other hydrocarbons, such as ethane (C2H6), propane (C3H8), butane (C4H10) and pentane (C5H12) are also shown, with their respective steam amounts required and the products gained. Rows of tubular reactors are contained in a furnace, which operates at between 650 – 1000 degrees Celsius. The hydrocarbon feed enters the system at a very high pressure, typically 20 – 30 bar. The process is carried out in the presence of a nickel-based catalyst which is packed into cylindrical tubes through which the steam/hydrocarbon gas mixture is passed. The catalysts act as surface for which the hydrocarbon will absorb and the steam. (Reference 2: Steam Reforming Flow Sheet) Justification Steam reforming is the most viable proposition as we have all of the raw materials available within easy access, whereas if we were to use other processes, then we would have to source other materials e.g. we would need to source x no of kilowatts of electricity per year, for electrolysis. Mass Balance Cp Values Energy Balance Material Costs Simple Plant Cost Using a base of around  £410 per ton of ammonia, and output at 550,000 tonnes, it would be assumed that the plant would produce  £225,500,000 a year of ammonia. The Burrup plant in Australia was built at a cost of  £457 million and produces roughly 800,000 tonnes a year of ammonia. Using the 2/3 power rule, as follows, will allow the costs of the new 550k p/a plant to be shown. C = Cref(S/Sref)2/3 C = 457000000 * (550,000/800,000)2/3 C =  £355,984,702 The output of the new plant is  £225,500,000, but the plant costs  £355,984,702 to build, so it would take around a year and seven months for the plant to be profitable, based on an estimation without including the costs of the raw materials. Taylor Method Pay Back Time Sustainability The environment is constantly changing, whether by nature or by human led processes. Sustainability is about trying to manage this change through balancing social, economic and environmental needs, both locally and globally for present and future generations. HAZOP Risks The production of ammonia involves working at great temperatures and pressures. As such, it is vital that the equipment used in the plant is designed to withstand these conditions to function properly. The high temperatures and pressures involved in the production of ammonia can potentially put tremendous amounts of strain on the pipes and vessels used. The risks associated with this are: * Explosions from sudden release of pressurised gases from ruptured vessels * Fragmentation from rupture of the pipes * Fire * Poisoning from exposure to leaked materials * Chemical or thermal burns, again from exposure to leaked materials Not only are these hazards life-threatening, they would also be very expensive to put right for the production company. These risks can be avoided by preparing the plant for the conditions that it is about to go through. It is more economically viable to run the steam reformer at as high a temperature and pressure as possible. Magnesium oxide-lined furnaces, MgO, has a melting point of around 2800 degrees Fahrenheit, making it ideal for lining the furnaces used in the production of hydrogen. Hydrogen itself will cause some materials to become brittle and eventually break. Hydrogen features an active electron and thus will behave like a halogen, causing erosion in the metals that it comes into contact with. This can be avoided by using high-purity stainless steel in the sections of the plant which will come into contact with the hydrogen. This steel must have a maximum hardness of 80 HRB on the Rockwell Scale. Ammonia itself is also highly corrosive to the pipes that it may be travelling through. For this reason, it is recommended that stainless steel is also used here, at a similar hardness of that shown above. Most ammonia plants use centrifugally cast high-alloy tubing to hold the nickel-base catalyst in the primary reformer furnace. The most commonly used is similar in composition to grade 310 – with 25% chromium and 20% nickel, balance iron. This has a carbon content in the range of 0.35 – 0.45% for improved high-temperature creep and rupture stress. Thermal protection of piping involves fire brick owing to the high temperatures involved.
