Search on the internet for a graph in your field of study that is Statistics Project
Search on the internet for a graph in your field of study that is misleading and discuss. Please also attach a link to the graph so that we can refer to the graph in your discussion - Statistics Project Example The third barââ¬â¢s height is more than double that of the second bar, yet the value it represents is not. There is definitely an inconsistency presented in the illustration of the valuation of the company. Another part of the graph which is misleading is the way the horizontal axis is scaled. Although the bars are equally spaced, the dates that they represent have uneven intervals. The first bar represented the month of December, the second bar represented January but the next two bars represented two dates in March. One also noticed that the valuation for May 2011 was not included in the graph. Furthermore, the month of July showed three separate bars indicating valuations for three different days in the month. The author of the graph should be consistent as to the time interval that he wants to depict in his graph. Does he want it to be bi-monthly or monthly? Moreover, if he chooses to make the scale on a monthly basis, figures shown should be the same date of every month. He can consider using the first day or the last day of the month. The consistency of information presented is vital to prevent misleading the interpreters of the graph. This illustration confuses the readers becau se the trend that is shown is not reflective of the real picture of the company valuation since different time intervals are shown. PrivCo.

Lukes Three Dimensions of Power
Lukes Three Dimensions of Power Lukes: On Power Power is a term that has seen much discourse and debate. The meaning of the word has been discussed and developed by many people from varying walks of life; academics, philosophers, politicians, and many others. It is a term whose understanding is crucial to how we, as humans, view and live in our social world, as it is a concept that governs our everyday living in several ways; some of which we are not even aware of. Political and social theorist, Steven Lukes, defines power in terms of, what he calls ââ¬Ëdimensions. These dimensions or faces of power are approaches that can be used to study power relations. Lukes looks at the theory of power in three dimensions of what he calls a ââ¬Å"conceptual analysisâ⬠(Lukes, 1974: 9). Lukes puts across an implicit proposition that the level and effectiveness of power in a given institution, can be analysed using these criteria (Lukes, 1974: 10). Lukes three dimensions of power can thus be used to study corporate power; an issue of g rowing concern and discourse space in the contemporary world. The one dimensional view of power proposed by Lukes is commonly known as the ââ¬Ëpluralist view of power (Lukes, 1974: 11). Dahl, Polsby and Wolfinger are some of the more prominent writers on this approach of looking at power (Lukes, 1974: 11). It is known as the ââ¬Ëpluralist approach to power because, through it, its proponents sought to show interest groups, in any democratic power structure, compete for power (Lukes, 1974: 11). Dahl differentiates the pluralist view from the elitist by asserting that his ââ¬Ëintuitive view of power involves not only the possession of, but the exercise of power; comes not only by reputation but also by execution (Lukes, 1974: 12). The argument of the one dimensional view of power asserts that the group/s wielding power can be determined by simply looking at who prevails when there are decisions to be made and there is ââ¬Å"observable direct conflictâ⬠(Lukes, 1974: 12). The pluralist approach emphasises the importance of actual ob servable behaviour and hence studies the outcomes of decision making (Lukes, 1974: 25). Such empirical study can be done through first-hand observation by analysis of official second-hand records (Lukes, 1974: 13). Dahl acknowledges that the power wielded by a group may be overt or covert, but the actual culmination of power is seen at the point when decisions are made, especially the decisions on controversial issues that are surrounded by the most conflict (Lukes, 1974: 13). Robert Dahl exemplifies the pluralistic view of power with his analysis of the power structure in New Haven, Connecticut; in the 1950s (Domhoff, 2005). In Dahls view, there were a number of influential groups whose opinions held weight when it came to making and influencing decisions about the city (Domhoff, 2005). His conclusion about the power structure in, New Haven was that no single group held the monopoly on power (Domhoff, 2005). Although there were inequalities within the society, the fact that power was dispersed among different elites with different interests at heart meant that the situation was one of ââ¬Ëdispersed inequalities; where no one group controlled all of the important resources (Domhoff, 2005). The one dimensional view of power is very simple to grasp and can be observed with relative ease. The theory gives a straightforward way of thinking about ââ¬Å"the behavioural study of decision-making power by political actorsâ⬠(Lukes, 1974: 57). It would be useful in many cases, especially where pluralist power structures have been established. However, the view fails to observe, in any system, the means by which the political agenda is controlled (Lukes, 1974: 57). In many cases, the exercise of power is more subtle and results from the use of mechanics beyond the scope of the one dimensional view. Lukes two dimensional theory of power is an elitist view theorized by Bachrach and Baratz, as a critique to the one dimensional pluralist view (Lukes, 1974: 16). This two dimensional view acknowledges the observable power of Dahls theory but asserts that power is exercised when issues are arranged specifically so that some are not discussed (Lukes, 1974: 16). By keeping issues of potential conflict off the agenda, observable conflict is completely avoided, but clearly ââ¬Ëpower over is still exercised (Lukes, 1974: 17). The first dimension would only look at the apparently open discussion and the results of conflict over matters actually allowed onto the agenda, but miss the more subtle exercise of power (Lukes, 1974: 19). Bachrach and Baratz also mention the latent power relations that occur in the event of ââ¬Å"non-decisionsâ⬠(Lukes, 1974: 18). This is when actor ââ¬ËB refrains from voicing and issue of interest to him/her, anticipating an unpleasant reaction from act or ââ¬ËA (Lukes, 1974: 18). ââ¬ËNon-decisions such as this consolidate the dominance of a particular group and help in maintaining the status quo of power relations (Lukes, 1974: 19). The two dimensional view of power thus consists of observable decision making and more subtle non-decision making. Decision making is the selection of one option from a set of alternatives, whereas non-decision making entails suppressing an interest that conflicts with those of decision-maker (Lukes, 1974: 19). In effect Bachrach and Baratz distinguish between potential and actual political issues, thereby drawing a distinct difference from the pluralist view that only looks at the ââ¬Ëkey issues that are actually in the discourse (Lukes, 1974: 20). From this distinction the authors draw the conclusion that behaviourism is false (Lukes, 1974: 20). In other words conclusions about power cannot always be drawn from observable behaviour. The two dimensional view of power recognises this; that the mechanisms of power and the way it operates can go beyond what meets the eye. Power is not only reflected in struggles within a system, but is also present in deciding what can get into the system and what cannot; defining the boundaries of the system (Lukes, 1974: 20). Crensons book The Un-Politics of Air Pollution: A Study of Non-Decision making in the Cities, a good example, of the two dimensional theory, is provided. Lukes asserts that the example also borders on the third dimension of power (Lukes, 1974: 42). The example focuses on two cities in Indiana; Gary and East Chicago. Both cities had similar populations and were facing a similar level and problem of pollution (Lukes, 1974: 42). East Chicago took measures to clean its air in 1949, while Gary only took action in 1962 (Lukes, 1974: 42). Crenson explains that the reason behind Garys inaction was that the citys prosperity was based on the only major industrial company in it; U.S. Steel (Lukes, 1974: 42). The issue was kept out of discourse for so long because of the reputation of U.S. Steel (Lukes, 1974: 43). The company exercised ââ¬Ësilent power and did not need to act, but it was simply its potential to act that kept policy-makers silent on the issue (Lukes, 1974: 43). The two dimensional view of power is a good critique on the one dimensional view as it aptly points out the flaws of the one dimensional view as it aptly points out the flaws of the one dimensional view, then goes on to set out a theory that holds water better than the first one. It fails, however, to satisfactorily examine the bias and control of power; ââ¬Å"it lacks sociological perspectiveâ⬠that is used to observe the methods by which ââ¬Å"latent conflicts within societyâ⬠are suppressed (Lukes, 1974: 57). Lukes is not satisfied with the two dimensional view of power as set out by Bachrach and Baratz (Lukes, 1974: 21). He offers three criticisms, which in his opinion, are the shortcomings of this view (Lukes, 1974: 21). From these, Lukes suggests that power can go deeper, into a ââ¬Ëthird dimension. The first criticism, of the two dimensional view, put forward by Lukes is that it, like the one dimensional view, is still too behaviourist (Lukes, 1974: 21). The argument of Bachrach and Baratz implies that the power exercised in the exclusion of information is deliberate; a conscious decision made by the decision-maker (Lukes, 1974: 21). This, however, is not the case. Such selection of issues may merely be the unconscious following of bias within a system and not an intentional attempt at exercising power by any particular group (Lukes, 1974: 22). The exclusion of certain issues from an agenda may also result from the norms of a particular society due to the prevailing modes of thought in the time and place in question (Lukes, 1974: 22). For example, before the twentieth century, women were generally viewed as naturally subordinate to men, thus issues of empowering women would not be seen as issues meriting consideration or attention. Lukes second criticism of the two dimensional of power argues that the theory still refers to the potential of conflict (Lukes, 1974: 23). The theory asserts that if people were made aware of the exclusion of certain matters, of interest to them, and the agenda they would react in order to protect their rights (Lukes, 1974: 23). Contrary to Bachrach and Baratzs theory, the ââ¬Ëair-pollution example showed that the decision makers, who had the interests of the people in mind, knew all of the relevant facts pertaining to the situation; however, they still took no action against U.S. Steel (Lukes, 1974: 43). This shows that power can act in a further ââ¬Ëdimension and take an even more insidious form. The third criticism Lukes has, of the two dimensional view of power, is that when it analyses if power has been exercised or not, it looks only at the subjective interests, policy preferences and grievances that are overridden (Lukes, 1974: 24). The view holds that if the observer can find no grievances there is the assumption that there is ââ¬Ëgenuine consensus on the issue at hand (Lukes, 1974: 24). The view, however, does not consider the possibility of a group having preferences that do not necessarily include all of its real interest (Lukes, 1974: 24). For example, in 2009 the number of American workers in trade unions was 12.3% and only 7.2% in the private sector (White, 2010). The ââ¬Ëpeak in the private sector was 30% in 1958 (White, 2010). Trade unions can organise and empower workers if they have significant membership and worker support. It is a real interest for workers to be involved in them, but partly due to the historical linking of trade unions with communism a nd partly due to other factors, few American workers choose to exercise their rights to join trade unions (White, 2010). Lukes sets out his own idea of how the most effective forms of power operate. He calls it three dimensional power (Lukes, 1974: 23). Lukes asserts that this form of power, to operate effectively, requires an acceptance of the status quo because of an accepted underlying ideology (Lukes, 1974: 23). Those who hold power within the system will be accepted by the people, due to the peoples belief in the system (Lukes, 1974: 23). In such a situation the preferences of the people can be manipulated to fall into line with the agenda of the rulers (Lukes, 1974: 23). Lukes calls his three dimensional view the ââ¬Å"supreme and most insidious exercise of powerâ⬠as it allows rulers to shape the preferences and perception of the masses as well as prevent them from having grievances (Lukes, 1974: 23). This is because, as Lukes argues, the people will ââ¬Å"see or imagine no alternativeâ⬠to the existing order ââ¬Å"or because they see it as natural and unchangeable, or because they value it as divinely ordained and beneficialâ⬠(Lukes, 1974: 23). Three dimensional power works by means of a mechanism called adaptive policy formation (Barber, 2007). This refers to a human reaction of reconciling oneself to ones misery, or altering ones attitude to console oneself in difficult circumstances (Barber, 2007). In embracing a particular system, people accept its consequences and thus resort to cognitive dissonance reduction as a functional means of dealing with oppression (Barber, 2007). It is, however, ironic to note that the worse off a people are, the less they demand (Barber, 2007). Rather than acting in favour of their interests, they accept repression and adapt to oppressive conditions. An example of three dimensional power at play is Sen and Nussbaums analysis of Bengal, where of the millions affected by the post 1944 famine, it was primarily men who reported to relief centres for aid, despite both sexes being similarly affected (Sen, 2008). In accepting their ââ¬Ëplace, of having limited rights in society, the women were n ot prepared to step forward and claim their rights to healthcare (Sen, 2008). Three dimensional power is the most supreme form of power as it gives rulers almost totalitarian power over the masses (Lukes, 1974: 23). Steven Lukes provides three theories of power and evaluates them, and at the same time building on their scope and complexity. His third dimension of power does a good job of exploring and explaining the mechanisms behind complex and entrenched power. The other two dimensions account for weaker forms of power that can be exercised. Lukes third dimension of power can be applied in explaining corporate power in the modern world. Corporate power is built on an unquestioned and accepted ideology, founded on the premise that it is the natural way of being of as Margaret Thatcher voiced out, ââ¬Å"There is no alternativeâ⬠. Acceptance of the free market ideology inevitably means acceptance of its consequences; the status quo of our world today. Lukes theory also helps us to explain why despite the destruction that is done to the planet, and the disregard for humanity, that characterises the system, it has survived and still thrives. Lukes, then, very aptly describes this form of powe r as both ââ¬Å"insidiousâ⬠and ââ¬Å"supremeâ⬠(Lukes, 1974: 23). Bibliography S. Lukes, 1974, Power: A Radical View ed.1, Macmillan: London. H. E.

freeaw The Awakening as a Story of Independence and Freedom :: Chopin Awakening Essays
The Awakening as a Story of Independence and Freedom Kate Chopin's The Awakening is a work of fiction that tells the story of Edna Pontellier, Southern wife and mother. This book presents the reader with many tough questions and few answers. It is not hard to imagine why this book was banished for decades not long after its initial publication in 1899. At that time in history, women did just what they were expected to do. They were expected to be good daughters, good wives, and good mothers. A woman was expected to move from the protection of her father's roof to the protection of her husband. Edna didn't fit this mold, and that eventually leads her husband to send for a doctor. It is here that Edna Pontellier says words that define The Awakening, "I don't want anything but my own way. That is wanting a good deal, of course, when you have to trample upon the lives, the hearts, the prejudices of others - but no matter_" As the book begins, Edna is a married woman who seems vaguely satisfied with her life. However, she cannot find true happiness. Her "awakening" begins when a persistent young man named Robert begins courting her. Edna begins to respond to him with a passion she hasn't felt before. She begins to realize that she can play roles other than wife and mother. Throughout the book Edna takes many steps to increase her independence. She sends her children away, she refuses to stay at home on Tuesdays (as was the social convention of the time), she frequents races and parties. Unfortunately, her independence proves to be her downfall. Edna stays married because divorce was unheard of in those days. She wants to marry Robert, but he will not because it will disgrace her to leave her husband. No matter how much Edna exceeds social boundaries, she is held down by the will of others, despite what she wants. In today's world divorce, sadly, is almost commonplace, but in her time she would have been an outcast of her society. By the end of The Awakening, Edna feels like a possession - of her husband, of her children, and of her society. The only solution she sees is to end her life, which she does by swimming out into the sea until her strength gives out. This is a very symbolic death. I feel the theme of The Awakening is deeper than the obvious themes of independence and women's rights. The Awakening presents suicide as a valid solution to problems that do not offer many choices.

Sai Baba :: essays research papers
On November 23, 1926, in a remote village in southern India, Sai Baba was born and given the family name of Satyanarayana Raju. He was one of the person born for success. Many stories began that after Sathya was born, strange "miracles" were beginning to occur. His was different from the children around him, and his actions and behaviors were obviously very strange. He was a vegetarian, unlike the rest of his family. He lived opposite his parents in a way that his life was nothing like theirs. At the age of 13, Sathya received some sort of pain in his foot. He was unconscious for a day, and when he awoke, his behavior had awkwardly changed. People believed that he was possessed by an evil spirit. In 1940, people began to call Sathya an incarnation of God. Sathya corrected this accusation easily by telling his father that he wasn't an incarnation of God, but of a Moslem holy man, named Sai Baba of Shirdi. He had passed away in 1918, eight years before Sathya's birth. Sathya's fame was widely spread when the stories of his "miracles" were passed on. He was known to heal the sick, and the blind. He also protected those who needed help. Sathya has physically appeared in two places at the same time and he has raised several people from the dead. The way Sathya's miracle stories have been passed on, reminds me of how Jesus' stories were passed on, and easily believed. They both healed the blind, the sick, helped the needy. But it is obvious that Sathya could never be compared to Jesus. Sathya's teachings have influenced many people, and have caused more than 10, 000 service organizations throughout the world. There are thousands of followers that have lived by the words and teachings of Sathya.

Analysis of Stephen Cranes, Maggie: A Girl Of The Streets Essays
Analysis of Stephen Crane's, Maggie: A Girl of the Streets Today in modern America, it has become almost impossible to avoid the tales of horror that surround us almost anywhere we go. Scandals, murders, theft, corruption, extortion, abuse, prostitution, all common occurrences in this day in age. A hundred years ago however, people did not see the world in quite such an open manner despite the fact that in many ways, similarities were abundant. Peopleââ¬â¢s lives were, in their views, free of all evil and pollution. They assumed they lived peaceful lives and those around them lived the same flawless lives untouched by corruption as well. Many were too blind to see beyond their own homes and into the lives of others who dealt with a more unfortunate fate. Those being the ones who lived in poverty, abuse, and other harsh conditions which were finally exposed to America in 1893 by a 22-year old college free lance writer who simply wished to show things as they appeared to him: bitterly real. Stephen Crane was Americaââ¬â¢s first re alistic writer who exposed the realities of the slums, tenement living and other unfavorable conditions to a very naà ¯ve American audience. Through hard work and his great devotion to the examination of the darker side of life Crane finally was able to publish his novel in which explored his experiences of the New York slums. Through his great use of dialect, irony and realism in his novel Maggie: A Girl of the Streets Stephen Crane is able to accomplish his goal of creating a vivid picture in his readerââ¬â¢s mind, portraying the harsh, abusive conditions of the many lives condemned to this fortune. Stephen Crane began his quest for the truth in the summer of 1889 while visiting his brother who lived in New Jersey (Peden, 104). While living with his brother Crane was drawn to the idea of realistic writing. He would travel to New York on almost a daily basis to witness and experience the poverty and abusive conditions of the slums (Colvert, 104). During his visits to New York Crane was able to establish an understanding and develop a feeling for what life was like in the slums. He soon acquired a craving for individuality and a yearning to express his experiences. He began his mission by placing upon himself the desire to become his own individual, separating himself from other writers of the era by using his unique style of r... ...

Cause and Effect Solar Energy
Cause/Effect: Solar Energy Solar radiation is an energy resource many times larger than mankindââ¬â¢s energy needs. Mankind has been able to capture/harness this energy resource, but only on a limited scale. Mankind has found that the use of the sun was quite useful. They used it to grow and dry crops, dry clothing, produce heat, and for light. The sun is a sphere, on the inside of the sun there is a continuous process of fusion in which hydrogen nuclei combine to from helium nuclei. There is less helium than that of hydrogen, which allows the sun to create energy.The energy is then radiated out of the surface of the sun, in which only a small portion is intercepted by plant earth. Just outside of the earthââ¬â¢s atmosphere, approximately 93 million miles from the sun, has the intensity of radiation of about 1. 36 kilowatts per square foot. This process is also called the Solar Constant. This energy is absorbed, dispersed, and reflected by the atmosphere; beaming its radiation to earthââ¬â¢s ground. Almost half of this energy is visible light, approximately half is infrared radiation, and a very small portion of it is ultraviolet radiation.There are many ways to convert this energy. Some use it to heat their water and homes; some convert it to Electrical Energy. Most of the worldââ¬â¢s energy needs have been met by converting solar energy into its electrical or mechanical forms. Electrical energy conversion of solar energy can be quite expensive. Much more than it would be to convert into thermal energy, but worth it in the long run. Solar panels or solar cells have been created to convert solar energy into mechanical energy, which can then be converted into electrical energy or used directly.This green energy alternative would cause a reduction in our environmental impact because it has less physical impact on the environment. They also help reduce the level of greenhouse gases produced and would decrease the demands of fossil fuels. Without a reli able, yet sustainable source of energy for the future, mankind will face a continued environmental destruction and continue to contribute to the growing problem of global warming. In order to stop the damage that is being done to the environment, we need to switch to an environmentally friendly energy production system.If we do not switch, the current facilities who rely mainly on fossil fuels, will continue to destroy the earth because they are leaving behind toxic residues and wasteful by products that will have to be dealt with for many years. The future lies with systems that eliminate these toxic and wasteful by products. Only by switching to fully renewable energy systems will humanity be free of these toxins. With our current technology and the expanding knowledge of tomorrow, wind turbines have a 30 year life span.The effort used to run these turbines is lower than the use of traditional power plants. Using wind energy to power turbines instead of plants using fossil fuels f or energy will reduce the overall impact of the U. S. Energy production. The before mentioned solar panel has a life expectancy of approximately 25 years. The total cost per kilowatt is way lower for solar panels than that of fossil fueled based power plants. These panels, once installed, need little to no maintenance. There is no monthly bill or added fees.Just like wind energy, solar energy is completely sustainable and they do not produce any physical by products. I believe that wind and solar energy is the perfect solution to the future of preserving the earthââ¬â¢s environment. Our environment is turning against us and there is a shortage of fossil fuels. It seems as though mankind as a whole is killing itself off. Mankind as a whole needs to rid itself of its dependency of fossil fuels. While wind and solar energy are not the only options available for sustainable energy solutions, in my opinion, they are the best alternative solutions.
