Simultaneous heat and mass transfer 4.8.1 Condensation of vapour on cold surface 4.8.2 Wet bulb thermometer 4.1 Introduction Our discussion of mass transfer in the previous chapter was limited to molecular diffusion, which is a process resulting from a concentration gradient. In system involving liquids or gases, however, it is very difficult to eliminate convection from the overall mass-transfer process. Mass transfer by convection involves the transport of material between a boundary surface (such as solid or liquid surface) and a moving fluid or between two relatively immiscible, moving fluids. There are two different cases of convective mass transfer: 1. Mass transfer takes place only in a single phase either to or from a phase boundary, as in sublimation of naphthalene (solid form) into the moving air. 2. Mass transfer takes place in the two contacting phases as in extraction and absorption. In the first few section we will see equation governing convective mass transfer in a single fluid phase. 4.2 Convective Mass Transfer Coefficient In the study of convective heat transfer, the heat flux is connected to heat transfer coefficient as [pic] -------------------- (4.1) The analogous situation in mass transfer is handled by an equation of the form [pic] -------------------- (4.2) The molar flux N A is measured relative to a set of axes fixed in space. The driving force is the difference between the concentration at the phase boundary, CAS (a solid surface or a fluid interface) and the concentration at some arbitrarily defined point in the fluid medium, C A . The convective mass transfer coefficient kC is a function of geometry of the system and the velocity and properties of the fluid similar to the heat transfer coefficient, h. 4.3 Significant Parameters in Convective Mass Transfer Dimensionless parameters are often used to correlate convective transfer data. In momentum transfer Reynolds number and friction factor play a major role. In the correlation of convective heat transfer data, Prandtl and Nusselt numbers are important. Some of the same parameters, along with some newly defined dimensionless numbers, will be useful in the correlation of convective mass-transfer data. The molecular diffusivities of the three transport process (momentum, heat and mass) have been defined as: [pic] ----------------------------- (4.3) [pic] --------------------------- (4.4) and [pic]--------------------------- (4.5) It can be shown that each of the diffusivities has the dimensions of L2 / t, hence, a ratio of any of the two of these must be dimensionless. The ratio of the molecular diffusivity of momentum to the molecular diffusivity of heat (thermal diffusivity) is designated as the Prandtl Number [pic] ------------------------ (4.6) The analogous number in mass transfer is Schmidt number given as [pic] -------------- (4.7) The ratio of the molecular diffusivity of heat to the molecular diffusivity of mass is designated the Lewis Number, and is given by [pic] ------------- (4.8) Figure Lewis number is encountered in processes involving simultaneous convective transfer of mass and energy. Let us consider the mass transfer of solute A from a solid to a fluid flowing past the surface of the solid. The concentration and velocity profile is depicted in figure ( ). For such a case, the mass transfer between the solid surface and the fluid may be written as [pic] ---------------------- (4.1 a) Since the mass transfer at the surface is by molecular diffusion, the mass transfer may also described by [pic] ------------------------- (4.9) When the boundary concentration, CAs is constant, equation (4.9) may be written as [pic] ---------------------- (4.10) Equation (4.1a) and (4.10) may be equated, since they define the same flux of component A leaving the surface and entering the fluid [pic] --------------- (4.11) This relation may be rearranged into the following form: [pic] -------------------- (4.12) Multiplying both sides of equation(4.12) by a characteristic length, L we obtain the following dimensionless expression: [pic] ----------------- (4.13) The right hand side of equation (4.13) is the ratio of the concentration gradient at the surface to an overall or reference concentration gradient; accordingly, it may be considered as

Assignment Tax essayEssay Writing Service Assignment Tax essay Assignment Tax essayOn 10 May 2013, the IRS issued regulations under section 336(e) that allow taxpayers in certain situations to elect to treat sales and distributions of 80Â  percent of a corporation’s (the target) stock as taxable sales of the target’s assets (Taxation of Cross-Border Mergers and Acquisitions, 2014). In such a way, the US fiscal policy aims at the enhancement of the transparency of fiscal operations and minimizes the risk of tax avoidance. The development of section 336(e) contributed to raising barriers on the way of international fiscal schemes that allow money laundering and transferring money off shore.Net investment income tax imposes 3.8% tax on net investment income of individuals, estates and trusts (Taxation of Cross-Border Mergers and Acquisitions, 2014). In such a way, the US fiscal policy aims at the accurate and effective taxation of investment incomes obtained by companies as well as individuals operating internationally. At this point , it is worth mentioning the fact that some companies have developed numerous schemes of tax evasion using their investments as the way to transfer their capital off shore or to other countries, where the fiscal legislation is more liberal and less restrictive. In such a way, the national legislation raises barriers for international schemes planned for tax avoidance and other schemes.Furthermore, the Foreign account tax Compliance act (FatCa) was enacted into law to address tax evasion by US taxpayers that hold unreported assets in financial accounts and undisclosed interests in foreign entities (Taxation of Cross-Border Mergers and Acquisitions, 2014). The tax evasion is a serious threat to the national economy. At the same time, international transfers are the most efficient way to complete tax evasions fast and effectively. Local law enforcement agencies have difficulties with the investigation of such crimes. The elimination of fiscal barriers and the enhancement of the foreign account tax policies help to minimize the risk of the violation of tax policies and prevents the problem of tax evasion.One of the major advancement in fiscal policies at the international level is the introduction of International Financial Reporting Standards. International Financial Reporting Standards introduce the common set of standards of financial reporting at the local and international level. In such a way, International Financial Reporting Standards help to balance the international legislation and fiscal policies, to harmonize them and develop common, transparent standards and principles that will contribute to the transparency of accounting and financial performance. International Financial Reporting Standards have been implemented since 2012. The first phase of the International financial Reporting Standards was introduced in 2013 and the preparation for the introduction of the second phase has started. 2014 involved the evaluation and assessment of the implementation of phase one of International Financial Reporting Standards. The accurate assessment is pivotal for the further implementation of phase two of International Financial Reporting Standards.Furthermore, the international cooperation in fiscal policies contributes to the tighter regulations and higher transparency of fiscal policies and accounting of businesses operating at the domestic and international market (Chernick Reschovsky, 2000). In this regard, the introduction of the automated information exchange international standard is an important step toward to the enhancement of the international fiscal policies and standards that facilitate the tax policy and tax accountability of businesses.At the same time, well-developed nations, including the US and the EU assist developing countries into the implementation of international accountability standards and fiscal policies that match international standards (Fighting Tax Evasion and Avoidance: A year of progress, 2014). In such a wa y, developed nations help developing ones to close fiscal gaps and help to introduce effective systems of monitoring and control. However, the key to the effective fiscal policies at the international level is the transparency of fiscal policies.However, one of the primary concerns of the international community in terms of fiscal policies was tackling tax heavens and aggressive tax planning that prevent the risk of the development of tax evasion schemes and transferring substantial financial resources offshore.3)International Financial Reporting Standards may become the tax framework within which international fiscal system can operate successfully. At the same time, the implementation of the common, global fiscal framework does not necessarily mean the resolution of the problem of tax avoidance. In fact, the tax avoidance occurs not only because of differences in fiscal policies and different policy standards but also because of the different in fiscal policies conducted by fiscal institutions of each country. At this point, the International Financial Reporting Standards can become a solid financial framework for well-developed nations with the solid legal system, well-established democracy, and low level of corruption. On the contrary, some developing nations, like Nigeria, for example, face the high risk of corruption. Even emerging economies, like China, suffer from the high level of corruption. Therefore, in case of the creation of the global tax framework after the implementation of International Financial Reporting Standards, countries with the high level of corruption may become new tax heavens for companies and individuals, who want to hide their profits and pay fewer taxes.At the same time, the risk of corruption is not the only obstacle for the successful introduction of the global fiscal framework. The implementation of the International Financial Reporting Standards and the elaboration of the common fiscal policy worldwide raises the problem the economic disparity in the global economy and the different dynamics of the economic development of different countries (Holzman, 2005). What is meant here is the fact that fiscal policies, including fiscal policies regulating international financial operations, are effective tools that help governments to stimulate business activities and balance the economic development. For example, in case of ‘overheating’ of the domestic economy, the government of a country may be willing to raise taxes to avoid the further ‘overheating’ that may lead to the crisis of overproduction and further economic decline. On the contrary, the government of a country that suffers from the economic recession may need to eliminate fiscal barriers and introduce more liberal fiscal legislation to attract more investors. In such a way, they can boost their economic development. However, the introduction of the International Financial Reporting Standards as the common, global tax frame work will become an obstacle for such independent policies conducted by governments. Obviously, at the moment, national governments are not ready to put international fiscal policies above their national economic interests. Therefore, even in case of the introduction of the International Financial Reporting Standards as the global tax framework, this framework will be unable to prevent the risk of tax avoidance.Nevertheless, the introduction of the International Financial Reporting Standards as the common, global tax framework can lay the foundation to the development of common fiscal policies and tax legislation. The introduction of the tax framework implemented internationally will stimulate the introduction of the common tax legislation that will help to prevent the risk of tax avoidance. Even though the International Financial Reporting Standards will not eliminate the problem of the tax avoidance point blank, but still such global tax framework helps to decrease such a risk. At this point, the elaboration of common international standards is an important step toward the effective prevention of tax avoidance at the international level. At any rate, the global tax framework helps to stimulate companies to introduce common strategies to match international fiscal standards. In the course of time, International Financial Reporting Standards can help to make the global business more transparent.In such a way, the International Financial Reporting Standards as the global tax framework will not bring immediate positive changes in terms of the tax avoidance minimization but still the global tax framework will have a positive impact on the development of international business and fiscal policies. Even though the International Financial Reporting Standards will not eliminate the problem of the tax avoidance, they will help to decrease the risk of the tax avoidance.

Richard Branson Leadership Style and Philosophy Essay

Richard Branson Leadership Style and Philosophy - Essay Example The present research has identified that over the years the Virgin Group has always been famous for their focus on customer service. However, Branson’s theory asserts that their highest priority is in making their employees as comfortable as possible. The reasoning behind this theory is that when a company has happy and satisfied employees, the employees will be able to give their best in the production process. As a result, the products and services that are produced by such companies will be in accordance with the expectation of the customers. As a result, customers will be satisfied and will remain loyal to the brand. This implies that there will be higher profits, which simply mean that investors will also be highly rewarded for their investment. Despite the fact that the Virgin Group has businesses in various parts of the world, it is improper to refer to the Virgin Group as a multinational. This is because all their businesses operate separately with Branson serving as a major shareholder in all cases. He also acts as the chairman and public relations supremo in all cases. Branson believes in product departmentalization, which refers to dividing an organization into various departments depending on the kind of product or service that they produce. For the sake of flexibility and the highly changing business environment, Branson believes that business organizations can highly benefit from using organic structures. Their companies use various types of departmentalization such as geographic and customer departmentalization because of the independent nature of their companies. Richard Branson should consider more postmodern organizations. This is because globalization has led to a business environment where factors that affect the functioning of a business are more than just those that are dominant in the geographical area in which they operate. It gets to a moment that even the individual organizations will have to expand past their comfort zone for t he sake of growth and competitiveness. However, it should also be noted that globalization leads to a situation where cultures are crossing borders. This is an implication that business organization needs to be more flexible so that they can be able to adapt to the changes that are brought about by the growth of globalization.

Developing Tyrrells Potato Chips - Essay Example For this purpose it may resort to more advertising, other promotions, offering discounts and better customer service. It can also try to compete by making its operations more efficient and thus bring down its costs. Alternatively, it can try to increase its economies of scale by more investment. Sometimes existing market may become so saturated or uneconomical that companies may enter new markets with existing products. Such a strategy falls under the category of market development. The obvious example is the entry of multinational companies into new markets with existing products they were selling in the home country or other markets. This entry could help the company to transfer loyalties of customers to buy its own products. This is very effective if the product is a well-known brand in the world and is being made available for the first time or in large quantities. If a new product is manufactured by a company and it tries to sell it in the same market it operates, then it is classified under product development. The company is confident that its new product will be attractive in the existing market itself. Companies try to market the new product to existing customers or even get new customers to buy them. The product could be completely new or can be used as accessories or add-ons to its existing products. â€Å"Sell new products or services in current markets. These strategies often try to sell other products to (regular) clients. These can be accessories, add-ons, or completely new products. Cross Selling. Often, existing communication channels are used.† (Product/Market Grid (Ansoff) 2008). Product diversification is an instance where a company develops or acquires a new product and market in an entirely new place. There are four ways of diversification that can be used by a company.

Relationship Between Doubt And Knowledge Philosophy Essay

Relationship Between Doubt And Knowledge Philosophy Essay Doubt is the key to knowledge (Persian Proverb). To what extent is this true in two areas of knowledge? Some definitions of doubt emphasize the state in which the mind remains suspended between two contradictory propositions and unable to assent to either of them. Doubt makes us aware and allows us to assess the reliability of the source of knowledge we are using. Doubt brings into question some notion of a perceived reality, and may involve delaying or rejecting relevant action out of concerns for mistakes or faults or appropriateness. The concept of doubt covers a range of phenomena: one can characterize both deliberate questioning of uncertainties and an emotional state of indecision as doubt. Doubt could be the key to knowledge but till it doesnt make the person reject everything he discovers. For example, if I doubt that I am going to flunk in IB then it is not a serious key to knowledge. If this motivates you and makes you study like mad then it is. If it discourages you then it is not. So, doubt is only a key to knowledge under certain circumstances. Moreover, there is always the danger of skepticism, that endless tendency to doubt and question. Regarding to skepticism and doubt it should be mentioned that regarding to Cartesian skepticism there is an aim to eliminate every belief that could be doubted and so Descartes keeps only the basic beliefs from which he will gain further knowledge. So doubt is the key to knowledge under certain circumstances. Doubt makes us aware and allows us to assess reliability of the source of knowledge we are using. In Science this means questioning things (attempt to falsify). Every discovery begins with a point for doubt. We see and perceive the world with the help of our senses but we dont know what is real. Natural Sciences are a quite reliable body of human knowledge, exactly because it is based on experiments and proof and has at its base the scientific method. In order to test the doubts and lead to a conclusion we follow a scientific method. First of all we ask a question which is associated with the doubt that we have and want to investigate. Then we evaluate information and so we are led to form a hypothesis. After that, we test our hypothesis with the help of an experiment in order to justify our doubt or not. In the end we observe what happened in the experiment and we draw a conclusion by either justifying our doubt or rejecting it. Avogadro, who was a scientist having studied mathemati cs and science, proposed his now famous hypothesis that equal volumes of gases, at the same temperature and pressure, contain equal numbers of molecules   and made the distinction between atoms and molecules, which today seems clear. However, Dalton rejected Avogadros hypothesis because Dalton believed that atoms of the same kind could not combine. Since it was believed that atoms were held together by an electrical force, only unlike atoms would be attracted together, and like atoms should repel. Therefore it seemed impossible for a molecule of oxygen, O2, to exist. Avogadros work, even if it was read appears not to have been understood, and was pushed into the dark recesses of chemistry libraries and ignored. In Science we can never be 100% confident in our results because during investigations many errors can occur and thats why doubting is legitimate in science. There might be some possible errors in the application of the scientific method (errors due to instruments, biases, problems of deduction/induction) which may lead to a weird result of an experiment and this would be confirmed by repeating the experimental procedure. A personal example is that in Chemistry class we had to observe water transport in a celery stalk. Due to a mistake in the method that we followed (we didnt stop the timer in the right time but later) the results came out to be strange and wrong. So, we had to repeat the investigation in order to be more accurate with time and therefore gain the results that we expect. In an IB Biology class the aim of the investigation was to see whether there is an effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato chip of given size or not. So, we followed a certain method and then we proved that our doubt, which was that the lower concentration of the sugar solution in the beaker the larger the mass of the potato will be, was justified. This is a hypothesis not a doubt. It looks like a doubt though. This example makes us understand the fact that we cannot reach a point where everything important in a scientific sense is known because through the doubts we investigate and find everyday new things that provide us knowledge. All the above points are associated with theories that are provisional. Provisional theories are theories that are accepted until we reach a point where we reject them. What leads us to the point of rejection is doubt. Moreover, it should be mentioned that similar to provisional theories is falsification. Falsification is again based on doubt. Falsification includes theories that are provisional and need justifications and evidence in order to prove the doubt or not. At that point it should be mentioned an example of Paradigm shift which means that some established theories that were doubted have been revised. Paradigm shift is a term used by Thomas Kuhn to describe a change in basic assumptions within the ruling theory of science. An application of Paradigm shift can be seen in the natural sciences and is the acceptance of Charles Darwins theory of natural selection replaced Lamarckism as the mechanism for evolution. Gregory Mendel, before he demonstrated the whole issue for monohybrid crosses he doubted it and made a falsification. His theory was seen as a provisional explanation but after he gained evidence by crossing varieties of pea plants which had different characteristics, he demonstrated his theory which is left in the history of science as Mendels Monohybrid Crosses. In conclusion for one more time this example shows that doubt is the key to knowledge. In Mathematics like in other subjects, we built on things that we previously learned or proved. We built on axioms which are self-evident statements. We take axioms without question and from these we can use the rules of logic to work out problems. An example of an axiom is that, an odd number is a number which can be written as 2n + 1, where n is a whole number. We could not gain knowledge if we have doubt on a fundamental assumption. On the contrary some theorists believe that having no doubt can lead to error in some cases. They believe that a little sense of doubt can mean that someone is open-minded and can gain further knowledge. But in pure mathematics, everything (logic, axioms, mathematical structureà ¢Ã¢â€š ¬Ã‚ ¦) is within the laws and conventions. Everything is deductively reasoned, and once something is proved, it is true no matter that space and time. Therefore, doubt in mathematics is not necessarily the key to knowledge. But again sometimes depends on how we define doubt. If we for example doubt that something in mathematics missing and trying to find it, we will certainly bring the development of the knowledge. One such example is Godels Incompleteness Theorem. Kurt Gà ¶del is most famous for his second incompleteness theorem, and many people are unaware that, important as it was and is within the field of mathematical logic and beyond, this result is only the middle movement, so to speak, of a metamathematical symphony of results stretching from 1929 through 1937. These results are: the Completeness Theorem; the First and Second Incompleteness Theorems; and the consistency of the Generalized Continuum Hypothesis (GCH) and the Axiom of Choice (AC) with the other axioms of Zermelo-Fraenkel set theory. The first incompleteness theorem states that no consistent system of axioms whose theorems can be listed by an effective procedure (essentially, a computer program) is capable of proving all facts about the natural numbers. For any such system, there will always be statements about the natural numbers that are true, but that are improvable within the system. The second incompleteness theorem s hows that if such a system is also capable of proving certain basic facts about the natural numbers, then one particular arithmetic truth the system cannot prove is the consistency of the system itself. Pythagoras theorem based on trigonometry was firstly demonstrated by Euclidis, a famous mathematician in Ancient Greece but because of his sudden death another couple doubted about the context of the theorem and therefore they reconstructed his theory centuries after his death. This example shows us that doubt is the key to knowledge since the couple guided by their doubt continued the theory and therefore expanded the mathematical knowledge. Cartesian doubt is methodological. Its purpose is to use doubt as a route to certain knowledge by finding those things which could not be doubted.] The fallibility of sense data in particular is a subject of Cartesian doubt. There is a debate on whether doubt in Ethics can or cannot be a key to knowledge. Critic and doubt in ethics examine our decisions in our everyday life and our actions from private and personal to public and political. Sometimes doubt in ethics tries to provide us with a guide for moral decisions and generally choices. Ethical axioms are tested not very differently to the axioms of science. Truth is what stands the test of time. As an example, let us suppose that abortion on demand is wrong. We want to collect relevant evidence and information to test whether our belief is reasonable and valid. One way to justify our belief is to say that abortion is wrong because abortion is murder and so murder is wrong too. Of course I should demonstrate the truth of the fact that abortion and murder are wrong and therefore to suggest that abortion which is wrong is true because the baby is alive and murder occurs since the life is taken unnecessarily. The philosopher Kant has worked with Ethics and doubt and has claimed that in order to judge an act, we should first consider what principle governs the act and to imagine what would happen if someone obeyed the principle. Kant also suggests that we judge on whether the act is good not by seeing if it produced good effects but by seeing if a consistent world is produced. Moreover another point that should be mentioned on ethics and doubt is the ethical theories. Philosophers came up with theories that help a person to define morally right behaviors. One such theory is the Deontological theory which says that people have a duty to refrain from actions that this duty will be determined by the nature of the action itself, therefore individuals should perform their duties regardless of the consequences, individuals have a duty to refrain from bad behavior and the bad behavior will be determined by the nature of the action. This theory can be applied to real-life situations where individu als have the option of doing right or wrong. The individuals should refrain from the bad behavior no matter which the consequences are. In both areas of knowledge we justify the fact that doubt is not always the key to knowledge. Actually in the second area of knowledge (mathematics), we observed that doubt can be a key to knowledge regarding to the definition that we give to doubt as a word. Therefore the starting statement of the essay, whether doubt is the key to knowledge is right but it should also be added under certain circumstances. What we would do overall is first of all not to doubt everything around us because on the one hand we gain knowledge from doubt but on the other hand, some things are deductively reasoning and once they have been proved, they are true for all time regardless of space and time.

History of East Saint Louis Essay

East Saint Louis, Illinois is a very small city it has a total of 89 streets as of today. Around in the 1860’s the city used to be called Illinois town. It was the fourth largest city in the state of Illinois. People knew one place they could get a job was in this city. The name East Saint Louis came about because of the terrible reputation it had when it was known as Illinois town so they decided to rename it hoping to overcome all the challenges they were facing. Jobs started to vanish, riots broke out and blacks moving there was the cause of all this. Most of the blacks that lived there came from down South where living conditions couldn’t be much worst. If they had a chance to move their children they did. They didn’t want their children to experience the life of picking cotton as they had. The whites there were upset and weren’t going to let the blacks take their jobs. As time grew and more blacks start to come, the more jobs started to leave so as the jobs started to leave the Population started to decline meaning taxes were higher and cuts had to be made. One investor had in mind if he bought some vacant lots that he could make a little money on the side, because the federal government was going to provide funds for â€Å"turnkey housing† to be scattered throughout the city, so the empty property will be his quick get rich scheme. When the housing Authority began building Low-income housing, real-estates agents and developers made a lot of money building and selling houses in West Belleville. The whites started to flee once they started to build in their neighborhoods. As time as started to pass things started to get worst, Violence were people were hurt, Homes being broken into, people being robbed, and killed. The population in the 1960 was around 81,728, as of 2011 the population is 27,000, with an estimated 14,000 resident living in public housing that leaves the tax burden on the 13,000. Forty percent of the residents draw public aid. The blacks who are able are fleeing away from the city as well. This makes the population continue to drop. In 1972, James Williams was the town black first Mayor he defeated Charles Merritts even though Merritts had the support of the white Democrats. Thereafter Merritts was sentence to federal prison for taking kickbacks as president of School District 189 Board of Education and also for putting a contract out to kill Clyde C. Jordan, a great leader for the town who was a fellow school board member and publisher of the Crusader black weekly newspaper. In the present year we can see that nothing has changed. All the corruption of this town has been going on since the beginning of time. Nothing really has change, we might see a new promising building here and now but the wrong people still holds the key to the scene of this all. We as citizens of East St. Louis, IL hopefully one day get the courage to stand up for what’s right and not worry about the consequence we might endure. Change is good and the city of East Saint Louis needs a tremendous change and we as the people can and shall make that happen.

Fan Violence in International Soccer Essay

Fan violence in international soccer is a very serious form of aggression and it must be given a lot of attention by the games’ stake holders. Fan violence in international soccer involves actions that are taken by the football supporters and fights between the supporters of rival teams may sometimes take place after the football matches. The fights could also be prearranged in locations that are away from the stadiums so that the fans can avoid the police interventions. Fan violence can be at times be prompted by violent actions which involve the players themselves or any other form of event that could be taking place during a game or even disturbances and riots that are sport related and often they occur for other reasons. Fan violence in international soccer has been on the increase as it is known as the existence of an essentially unstable and an abnormal temperament in some individuals who happen for some reason to have taken soccer as an arena in which they act out their instabilities. (Smith, 1983) It has become very difficult to deal with the offenders in the football matches and the international football federation has had difficulties punishing the spectators who misbehave themselves . The international football federation has also had to deal with issues that prompt fans violence in soccer matches such as providing seats in place of standing accommodation, initiating maximum cooperation between the police and the football clubs and also ensuring that there is an absolute acceptance of the referees decisions by everybody in the football arena. The key stakeholders of the soccer game are the international football federation who ensure that the punishment that is given to the offenders and to those who participate in football hooliganism should match the seriousness of the offence. It is notably very true that the consumption of alcohol is a very important factor in crowd misbehavior especially in places where the football matches are taking place. (Smith, 1987) The football fans are mainly controlled by the activities and the popularize of different clubs . This makes it a contest as they embark on slogans chants and even songs so that they can demonstrate their support to the teams they support. The violence that exists between the sets of fans is seen as a part of their participation in the game. Violent fans and those who mainly participate in violent actions in the international soccer are basically those people who are young and unemployed. It also involves also those who are members of fanatic clubs and they are poorly educated since they attribute most of their behavior to the external factors rather than the internal ones. In most case there are usually two matches going on in a football stadium and whereas one match concerns the football teams that are on the pitch and the second match usually involves the fanatic fans whose interests are not in the game as such but on the opportunities which are offered by the football such as meeting the club mates and giving vents to their emotions and energies in the battles with others. (Smith, 1983) It is at times very complex to handle fan violence in soccer ethically since the game requires intense physical contact which may cause harm of injury. When the stake holders access the moral status of an action, they examine the issue of consent by the person on whom the action has been performed. Actions by the fans which are outside the rules of the federation of international soccer are considered to be morally unacceptabl. Reference: Smith, M.
