Performance Theory or Theorizing Performance Essay

Performance Theory or Theorizing Performance - Essay Example From this paper, it is clear that the scene is a mixture of all kinds of elements that make a script worthwhile and captivating to the audience. The script has the elements of love, hatred, anger, irritation, etc. that make it attention grabbing for the audience and make it interesting and challenging for the role player as well. The use of material objects at the scene was outstanding and made it easy for us as well as the audience to focus on the main plot of the script. For example, the starting scene when Will is sleeping on Skyler‘s bed shows a deep intimacy he shares with her and the closeness of their relationship. But at the same time, the scene portrays unpredictability to their relationship. The language of Will shows his aggression which is a reflection of the child abuse he went through in his early days with his father. He is continuously using abusive language which shows that he is not a follower of any culture and lives his life according to his own rules. The u se of abusive words adds up to the aggression in Will character. Moreover, the intensity of his anger is indicated with the deliverance of his dialogues. He doesn’t let Skyler complete the whole sentence and cuts her in between. And even if she says something Will doesn’t listen to her and says whatever comes to him. The performance displayed was an implication of the performance theories in theatrical performances. All the blocks of structured performance were connected with the use of right content, speech, objects, language, and actions.

Choosing University Essay Example for Free

Choosing University Essay Choosing a university is imperative to your further studies. Every course and every university is different and each student wants different things. The chance of finding a perfect match can be a challenge and you will certainly need to decide what is most important to you. It is all a matter of priorities which you feel are important to you,after all you will be the one who has to study on the course and you maybe living there for over 3 years or more. When choosing a university, there are a few general things you may want to consider before researching more specific factors. First of all, I propose a good way to start researching universities is to look at university league tables, which is the university rankings. This will allow you to see how well a particular university is doing in comparison to others. A higher placing in the table generally means facilities, grades and teaching standards are better. Remember that going to a university higher up in the league tables does not automatically mean you will achieve better grades, it is down to how well you perform during the course. According to the rankings, the choice of your subject and the type of course will narrow down the number of potential universities to just a few. Moving on to my next point, Where is the universities located? This means that whether you want to go to a universities in a big city or somewhere quieter. Studying in big town will have a lot of disturbance and distractions awaiting, thus lose your concentration in your studies. Remember that the cost of living will be higher in large cities, which may affect your budget significantly. On the other way round, studying in urban area will convenient your living there as you are closer to the shopping centre to buy living necessities and able to enjoy delicacies sometimes. Another point that I would like to emphasize is the social activites of university is a very important part of a student life, therefore it is vital to ensure the range of social, sports, and cultural activities and clubs offered by the university match your requirements. This is because taking a degree is not all studying, it is important to balance your life with some fun. This in turn can help you to find the right balance between working and socialising in the future.

How to Write a Synthesis Essay :: Synthesis Essay

What is a synthesis essay? A synthesis essay draws on two or more sources and combines their ideas into a coherent whole. What do I need to write one? Writing a successful synthesis essay will require you to do four things: read accurately and objectively, see relations among different viewpoints, define a thesis based on these relations, support the thesis effectively. You will not discuss all the points in every essay; but you should use every essay assigned, and you should use points from each that are appropriate for the thesis of your own essay. How do I write it? A synthesis essay may be developed in several ways, including the following: Thesis supported by examples. Develop a thesis based on common points among the works, and Support the thesis with appropriate examples from each work. This strategy works well with essays that approach a subject from highly diverse viewpoints. Comparison and contrast. Discuss the similarities and differences in the writers' viewpoints and draw whatever conclusions are possible from your comparison. Argument. If you have a clearly defined opinion about the subject, support that opinion by incorporating the valid viewpoints of the writers of the essays you have selected, and show the weaknesses of those ideas which you feel are not valid. What steps should I take in writing this essay? Consider using the following procedure for writing your essay: 1. Read carefully. First, skimming through the readings and look for similar issues in each essay. Reflect on those issues, and jot down your ideas. Reread and decide on one topic that will unify your essay. Note each essay's thesis and main points. Finally, take notes. 2. Next, determine your thesis. A thesis is a direct statement of a main issue or idea that you have developed from studying the essays. If you are writing a comparison/contrast essay, your thesis may explain the main points of agreement and disagreement among the writers you are dealing with. If you are writing a thesis-with-examples essay, your thesis may state the main idea you have developed from your readings, which will be supported with examples from the readings in the body of your essay. If you are writing an argument, your thesis will state your opinion about the subject and will indicate that you will be supporting your views through an analysis of the essays. 3. Then, organize your essay with your thesis in mind. The type of organization you use depends on your thesis, but in general you should be able to use either block-by-block or point-by-point organization with any of the essay types.

Fossils Nurse Essay

A fossil is the prehistoric remains of a plant or an animal. Fossils are usually are kept at their best when they are buried under many layers of sand and mud. Under the great pressure from the ground, the sand and the mud become sedimentary rock. The minerals combine forming a mould of the plant or animal under the ground. A fossil can be a trace fossil or a body fossil. A body fossil is what actual organic material from a creature or plant (like a bone). Trace fossils are signs of plants and animal activity that have been preserved in rock. For example, dinosaur tracks, trails and dung are all trace fossils. A body fossil is usually composed of bones of an animal. Preservation of the â€Å"soft† tissue of a body is rare especially over long periods of time. Most body fossils are made when an animal dies and falls, or is washed into a steam, and is covered with mud. In a few cases, though, fossils have been preserved by freezing (as with mammoths in Siberia and Alaska) or when the animals have become stuck and died in a tar pit (such as the famous La Brea tar pit near Los Angeles, California). Sometimes a fossil is the result of a volcanic eruption. Ash and mud from the volcano can cover animals and plants killing them at the same time. Geology is the study of the Earth, the materials of which it is made, the structure of those materials, and the processes acting upon them. It is also the study of organisms that have inhabited our planet. An important part of geology is the study of how Earths materials, structures, processes and organisms have changed over time. Fossils are linked to geology because, it is the study on how the world has build up over the years and fossils are animals and plants from over the years. They have changed over time because they have become smaller and form in different ways like freezing and volcanic eruptions. Over the years fossils have told us about life forms we had no idea about and is proved with the fossils or bones we have today in museums. This is how fossils are linked to geology.

Aesops Fable of the Crow and the Pitcher

Aesops Fable of the Crow and the Pitcher One of Aesops most popular animal stories is this one, of a thirsty and ingenious crow. The text of the fable, from George Fyler Townsend, whose translation of Aesops Fables has been the standard in English since the 19th Century, is this: A Crow perishing with thirst saw a pitcher, and hoping to find water, flew to it with delight. When he reached it, he discovered to his grief that it contained so little water that he could not possibly get at it. He tried everything he could think of to reach the water, but all his efforts were in vain. At last he collected as many stones as he could carry and dropped them one by one with his beak into the pitcher, until he brought the water within his reach and thus saved his life. Necessity is the mother of invention. History of the Fable Aesop, if he existed, was a slave in the seventh century Greece. According to Aristotle, he was born in Thrace. His fable of the Crow and the Pitcher was well known in Greece and in Rome, where mosaics have been found illustrating the crafty crow and the stoic pitcher. The fable was the subject of a poem by Bianor, an ancient Greek poet from Bithynia, who lived under the emperors Augustus and Tiberius in the First Century A.D. Avianus mentions the story 400 years later, and it continues to be cited throughout the Middle Ages. Interpretations of the Fable The morals of Aesops fables have always been appended by translators. Townsend, above, interprets the story of the Crow and the Pitcher to mean that dire circumstance gives rise to innovation. Others have seen in the story the virtue of persistence: The crow must drop many rocks into the pitcher before he can drink. Avianus took the fable as an advertisement for the suave sciences rather than force, writing: This fable shows us that thoughtfulness is superior to brute strength. The Crow and the Pitcher and Science Again and again, historians have noted with wonder that such an ancient tale- already hundreds of years old in Roman times- should document actual crow behavior. Pliny the Elder, in his Natural History (77 A.D.) mentions a crow accomplishing the same feat as the one in Aesops story. Experiments with rooks (fellow corvids) in 2009 showed that the birds, presented with the same dilemma as the crow in the fable, made use of the same solution. These findings established that tool use in birds was more common than had been supposed, also that the birds would have had to understand the nature of solids and liquids, and further, that some objects (stones, for example) sink while others float.

Free Essays on Airline Industry Free Essays on Airline Industry The airline industry has been subject of intense price competition since it was deregulated, and the result has been a number of new carriers which specialize in regional service and no-frills operations. These carriers typically purchase older aircraft and often operate outside the industry-wide computerized reservations system. In exchange for these inconveniences, passengers receive low fares relative to the industry as a whole. This research examines two low fare air carriers, ValuJet and Southwest Airlines. By investigating these air carriers, we can better understand the economic impacts of price versus service in the airline industry as a whole, as well as, the impacts on passenger and investor confidence. Until 1978, air transport rates were approved by the government, which meant that price was not a primary competitive factor. Instead, airlines would compete on service and image. The airline industry was dominated by giants (American, United, TWA) which offered nationwide and some international service, and by regional carriers, such as Southwest, which offered short trips between airports not served by the nationals. Deregulation of the airline industry brought about in 1978 introduced a situation in which the national and regional carriers were suddenly able to compete in an environment that resembled a free market. Rate schedules were lifted, price fixing was eliminated and route management was removed. The main factors that affected whether an airline could serve a particular city was whether or not that city had enough gates for the new carrier, and whether the carrier was able to afford to purchase them. Companies such as Southwest recognized potential for low fares, and began building a niche for themselves by offering low fares with equivalent low levels of service. Southwest?s success gave rise to a new generation of low fare airlines, with ValuJet entering the market in the early 1990?s. Unfortu...

Free Essays on Airline Industry Airline Industry General Environmental Analysis The airline industry is very stable and unlikely to change in the near future. There are many reasons for this. Air travel continues to grow and will continue in this fashion as long as the economy stays in an upward trend. US domestic air traffic grew 2.3% in 1998 and 3.5% in the first six months of 1999 according to Air Transportation Association. The percentage of flyers has increased an average of 2% each year and the percentage of people who have ever flown before increased from 73% in 1993 to 81% in 1997. (Airport Transport Association, Internet). The top three reasons that people fly are business trips (47%), visiting relatives (38%) and going on vacation (13%). Most airline revenues are gained from the fares they charge these passengers, but they also earn ancillary revenues from transporting mail, shipping freight, selling in-flight services and from serving alcoholic beverages (Airport Transportation Association, Internet). The primary target market of airline passengers to day is the business traveler because business trips account for the majority (47% ) of airline flights. Though this percentage of business trips is slowly declining, the actual number of business travelers is increasing. The business traveler fits the description of the average airline passenger of being male, between the ages of 35 and 54, having a household of $60,000 or more and lives in the western region of the country (Airport Transportation Association, Internet). The business traveler tends to be very price inelastic in terms of plane fares and as a result, airlines provide benefits to them such as priority check-in, expedited baggage handling, frequent flier miles and in-flight cell phones to business people to entice them to fly with their carrier. The other segment of the airline market is that of leisure travelers. These passengers tend to be extremely price sensitive which is exactly opposite...

Site and Situation in Urban Geography

Site and Situation in Urban Geography The study of settlement patterns is one of the most important aspects of urban geography. Settlements can range in size from a small village with a few hundred residents to a metropolitan city of over one million people. Geographers often study the reasons behind why such cities develop where they do and what factors lead to their becoming a large city over time or remaining as a small village. Some of the reasons behind these patterns are thought of regarding the areas site and its situation. Site and situation are two of the most important concepts in the study of urban geography. Site The site is the actual location of a settlement on the earth and is composed of the physical characteristics of the landscape specific to the area. Site factors include things like landforms, climate, vegetation types, availability of water, soil quality, minerals, and even wildlife. (i.e., is the area protected by mountains or is there a natural harbor present?) Historically, these factors led to the development of major cities worldwide. New York City, for example, is located where it is because of several site factors. As people arrived in North America from Europe, they began to settle in this area because it was a coastal location with a natural harbor. There was also an abundance of fresh water in the nearby Hudson River and small creeks as well as raw materials for building supplies. Also, the nearby Appalachian and the Catskill Mountains provided a barrier from moving inland. The site of an area can also create challenges for its population. The small Himalayan nation of Bhutan is a good example of this. Located within the worlds highest mountain range, the terrain of the country is extremely rugged and hard to get around. This, combined with the incredibly harsh climate in many areas of the country has made much of the population settle along rivers in the highlands just south of the Himalayas. Also, only 2% of the land in the nation is arable, with much of it located in the highlands, making a living in the country highly challenging. Situation The situation is defined as the location of a place relative to its surroundings and other places. Factors included in an areas situation include the accessibility of the location, the extent of a places connections with another, and how close an area may be too raw materials if they are not located specifically on the site. Though its site has made a living in the nation challenging, Bhutans situation has allowed it to maintain its policies of isolation as well as its own highly separated and traditionally religious culture. Because of its remote location in the Himalayas getting into the country is challenging and historically this has been beneficial because the mountains have been a form of protection. As such, the heartland of the nation has never been invaded. Also, Bhutan now controls many of the most strategic mountain passes in the Himalayas including the only ones into and out of its territory, leading to its title as the Mountain Fortress of the Gods. Like an areas site, however, its situation can also cause problems. For example, Canadas Eastern Provinces of New Brunswick, Newfoundland and Labrador, Nova Scotia, and Prince Edward Island are some of that countrys most economically downtrodden areas due in large part to their situations. These areas are isolated from the rest of Canada making manufacturing and the little agriculture possible too expensive. Also, there are very few close natural resources. Many are off the coast, and due to maritime laws, the government of Canada itself controls the resources. And, many of the traditional fishing economies they did have are now crashing along with the fish populations. The Importance of Site and Situation in Todays Cities As shown in the examples of New York City, Bhutan, and Canadas East coast, an areas site and situation played a significant role in its development both within its boundaries and on a world stage. This has occurred throughout history and is part of the reason why places like London, Tokyo, New York City, and Los Angeles were able to grow into the prosperous cities that they are today. As nations around the world continue to develop, their sites and situations will play a large role in whether or not they will be successful. Though todays ease of transportation and new technologies such as the Internet are bringing nations closer together, the physical landscape of an area, as well as its location in relation to its desired market, will still play a large role in whether or not such areas will grow to become the next great world city.

This is evident by the way Karl Lindner the white neighborhood’s representative asks to buy them out with a very generous offer. At the end of the play, the family leaves with their pride of being black and refuse the money offered by the white people. This paper therefore seeks to analyze the play A raisin in the sun and show how racism was deeply rooted back in the 1950’s and the manner in which blacks always wanted to pursue the American dream where they would hope to have â€Å"life, liberty as well as the pursuit of happiness†. Looking at the social climate of the 1950s and 1960’s as displayed by the play, it is easy to see that black people lived in poor conditions as compared to white people. In this era, most of the public buildings in the white n eighborhood were full of racial segregation. White people did not mingle or live together with black people as they were thought to be of an inferior class. Many whites were also of the belief that by having black people in a white neighborhood, the value of their property would go down1. ... given in the year 1952 by the Women’s committee to end discrimination in the medical services, it was seen that there was a high connection between high death rates in black people and hospital segregation2. Still in the schools black children attended sub-standard schools as compared the white children. In most of the public schools together with colleges, racial segregation was rampant and blacks attained marginal education as compared to white children. Despite the fact that the Supreme Court in the year 1954 made a ruling using the Brown v. Board Education, that school segregation was not constitutional, it took quite a number of years for it to be implemented. In terms of the economic climate that the blacks faced during the 1950s, there was a lot of racial discrimination, which led to blacks getting very low paying jobs. After the Second World War, black veterans went back home so as to share their victory and live the American Dream. This however was not to be a reality for them as they were prohibited from settling in the upcoming suburbs. This is similar to the raisin in the sun play where Mama and her family are being asked to leave particularly because it is a white neighborhood. In the 1950’s black Americans have no choice but to live in cramped areas whereby even finding good jobs is equally hard. Unfortunately, candidates who are educated and are highly qualified for good jobs are not also lucky and they also face racial discrimination when the hiring process is on; for this reason, they have to settle for odd jobs. Black American population between 1940 and 1970 had drastically increased from 50 percent all the way to 80 percent. In the south, many black Americans lost both mining and share cropping jobs particularly due to the government investing

Influence of African Art on European and American Art since 19th Research Paper

Influence of African Art on European and American Art since 19th century - Research Paper Example The main factor that makes the African art to be influential is the fact that most of the African artwork were designed during the colonial times and hence had direct impact on the European and American who were the major colonialist. Most of the African art were designed to expose the limitations imposed on the Africans by the colonialist. A study that was conducted by Salah that explored the twentieth century history and sociology of the western countries reveals that most of famous and creative artist comes from previously colonized territories, including Africa, London and Rome. This signifies the fact that Africans played a significant role in shaping the art industry both in Africa and western communities. The study states that the intellectual employed by African during production of its art is essential to understanding the global modernity. This is because most of the African art overlaps with that of the European counterparts. African artist employed different styles in the ir artwork. These include the Masquerade and masking traditions have a role of underlining the historical continuities with a pre-colonial past. The use of these forms of tradition compounded by creativity employed has made most of the African art to be among the most admired. It has encouraged the modernist from the entire continent to continually engage in African masking traditions. They masking and masquerade constitute the major forms of art of presenting a person. In order to fully discuss the reasons behind the superiority of African art, it is important to first explore the meaning of the term Africa (Sey 459). From artistic point of view, Africa is described as a complex intellectual construct that signify different opinions. Africa integrates certain cultural values, cultural features and values meant to depict Africa as a continent (Salah 472). One unique thing about Africa and art is that Africa went through a myriad of political and social changes. Africa is a continent with a lot of experiences in aspects such as slavery, colonialism and diasporization of African people and cultures. Because of all these experience, Africa is a complex continent. This is why most of the artistic activities made in Africa are outstandingly unique. They are normally carved out based on the cultures, experiences and the day to day encounters. This means that artwork is just a representation of social or political phenomena. In this context the African art are products of the historically complex encounters. One thing that should be notes as far as African art concerns the dynamic nature of the artwork (Salah 452). Social changes that are

A Economics Commentary on Protectionism Assignment

A Economics Commentary on Protectionism - Assignment Example Increase in tariffs increase the revenue for government as it serves as a tax which is imposed whereas quotas may or may not increase the revenue for the government. However, there are also welfare impacts of the quota and tariffs also on the domestic economy which can indicate that the protectionism may not be good for the economy. The above diagram shows the impact of having quotas on the supply level and the prices and how the imposition of quotas will create welfare loss for the consumers. The above graph indicates that the world supply is elastic in nature and is indicated by a horizontal line showing SH+Q. The line DH indicates the overall demand in the market and the interaction of supply and demand indicates the market clearing conditions at different price and quantity levels. Recently, US has imposed higher tariff on the import of tires from China in a bid to protect the ailing tire industry of the country which resulted into the job losses for last five years. (Whoriskey and Kornblut). Now that tariff is imposed on the import of Chinese so that the production is reduced. As a result of this, the price level will move to Pw’ from Pw in local market for locally manufactured tires. As a result of the tariff imposition, the supply will reduce and the aggregate supply curve will shift leftward to SH. This reduction in the supply and the increase in prices will therefore result into the decrease in the supply and the increase in prices therefore will not only result into the reduction of consumer surplus but will also result into the welfare loss. This is because the imposition of the tariff increases the domestic prices over and above the world prices thus making the domestic consumers more worse off owing to the increase in the prices. The imposition of tariffs on the import of Chinese tires will first disrupt the equation of trade balance between both the countries as US’s import of tires from China will reduce as the imported

Explanations for Inequality Essay Example for Free

Explanations for Inequality Essay There are many sociological explanations for female inequality in society. Inequality is where something/ someone is seen as not equal compared to something else. For example men have more opportunities than women in life, suggesting females suffer huge inequality in many factors of life. Firstly, Anne Oakley speaks about how women suffer inequalities in the work place. Oakley notes that after the industrial revolution in Britain acts were passed to limit women working; in 1851 one in four married women worked whereas in 1911 one in ten worked. During the Victorian era the ideology that a womans place was in the home became truly established and industrialisation led to the separation of men from the daily routine of domestic life. Now it is claimed that women suffer from four main inequalities in the workplace. Firstly, there is the much debated pay gap in which, even though legislation to stop unequal pay was introduced in the 1970s, the although narrowing pay gap is still visible between men and women. Secondly half of all females in employment are in part time employment; this form of employment is often less secure with fewer benefits. Thirdly, women suffer from vertical segregation; this is sometimes referred to as the glass ceiling effect. Women are seemingly unable to achieve the higher ranking positions and are stopped from achieving managerial positions by an invisible barrier. Lastly, women are said to suffer from horizontal segregation which is the idea of gendered jobs. Liberal feminist Oakley blames the dominant housewife mother role, suggesting that a wifes role is primarily domestic, thus inequality is inevitable. There are criticisms for this study however, suggesting that it sees inequality as simply just a matter of time. As well as biological factors, and time Victoria Beechey, from a marxist perspective has deleveloped a study which sees women as a reserve army of labour. She uses this in order to explain the position of women in the labour market. Marx argued that capitalism required a reserve army of labour, that is a spare pool of potential recruits to the labour force. Beechey identifies a number of ways in which women in modern Britain are particularly suited to form part of this reserve army. She suggests that womens jobs are least likely to be covered by redundancy legislation, so its cheaper to make them redundant rather than men, suggesting huge inequality as it shows women are superior to men. Furthermore she suggests that unemployed married women may not be elegible to receive state benefits if their husbands are working, and for this reason they might not appear in unemployment statistics. Beechey says that women who are made redundant are able to disappear virtually without a trace back into the family. She also suggests that women are more likely to accept part time work due to their domestic role, women tend to be happy in accepting less wages than their husbands as they can rely on their man. This makes you realise that still in society, women who don’t work, even though they want to is still frowned upon, and it would be easier for men to get jobs than women, showing inequality between women and men. Bruegel challenges this theory, she questions the assumption that the interests of capital must be served if women are to be used as a reserve army of labour. She points out that women can also benefit capitalism by producing domestic labour in the home, as this reduces the amount that needs to be paid to male workers. Linda Mcdowell like Beechey also talks about part time work, and why women are more likely to accept it. She applies post-Fordist theory to female employment. Post-Fordism suggests that there has been a move away from mass production to more flexible production of specialist products. Businesses keep a core of highly skilled workers, but most other workers are temporary, or part time, or work is contracted out to other firms. Women tend to be concentrated in the more flexible jobs, particularly part time work. This suggests that even today it is still hard to for women to have a good career like men, as due to other priorities part time work may be the only suitable explanation. Lovering found evidence to support this theory suggesting that post Fordism trends affect only some women. Furthermore, post-Feminists argue that the feminism of the 1970s and 80s is out dated because it sees all women as sharing the same interests and ignores the diverse interests of different groups of women. Natasha Walter believes that there is still much that feminists need to change. She believes that the post-feminist emphasis on political correctness and language neglects the continuing problems of inequality which affect all women. Women still tend to suffer from problems such a low pay, lack of childcare, the dual burden of paid employment and domestic labour, poverty and domestic sexual violence. Following up on this Germaine Greer suggests that women cannot be themselves as they still have to act in the ways men want them to be. This suggests that women suffer in the hands of men, due to them being more powerful etc. Women thus are brainwashed into being how men want them to be, for example, clothing and make up. Radical feminists also believe that mens power and control over men is the main reason for inequality. They believe that patriarchy is the most important concept when explaining gender inequalities. They tend to focus on the power relationships that are experienced in private, in particular the significance of sexuality and the use of violence. Kate Millet believes that oppressive and unequal relationships between men and women originate not in wider society, but in the intimacy of personal relationships, in sexual partnerships and in families and households or various kinds. She believes personal relationships are also political in that they are based on different and unequal amounts of power which are determined by sex and which are reinforced in every aspect of wider society. Culture, government, tradition, religion, law, education and the media all reflect patriarchal leadership and power. Critics of this theory suggest that this theory is ultimately biologically deterministic, since the biological facts of reproduction are at the heart of the position. Not all sociologists believe that inequality is still a major factor in society. Catherine Hakim (economist) suggests a Rational choice theory. She is critical of all feminist positions. She argues that feminist theories are both inaccurate and misleading, and that women are not victims of unfair employment practices. She identifies five myths; womens employment had not in fact been rising, women were less committed to work than men, that their childcare responsibilities were not the main reason for them working part time, that part time jobs were not necessarily worse and finally that women were less likely to be in stable employment. This goes against all feminist explanations and suggests that inequality is not as we see it, and a lot has changed. However, Crompton argues that Hakim underplays the structures within which women make choices. In particular she cites the development of the male bread winner. Other sociologist like Hakim who neglect mainstream feminist values are the black feminists. They are critical of mainstream feminism suggesting that they neglect the particular problems that black women face. Bourne argues that white feminists are luke-warm about tackling racism because they enjoy social, economic and political privileges which make them part of the system which oppresses black women. Further more Yuval-Davis develops this theme claiming that non-black minority ethnics such as Iranian, Cypriot, and Chinese women not only face racism, they also face cultural patriarchy which is particular to their communities. This is suggesting women are not really all in the same position and it affects people differently. White feminists tend to reject black feminists and ignore them from most of the studies and theories.

Regeneration By Pat Barker Analysis English Literature Essay

Regeneration By Pat Barker Analysis English Literature Essay The story takes in the past. The entire story is in 1917. You can know that because it is during the First World War. In the beginning Rivers is reading a poem of Sassoon from July 1917 and in the end he wrote a date on a file of Sassoon which said: Nov. 26, 1917. In total I think the story takes a couple of months. In the beginning of the story Rivers reads a poem of Sassoon what is written in July 1917. So it will be in July or later. The story ends at November 1917 because that is what Rivers writes down on Sassoons files. So in total it will probably take a couple of months S. Sassoon July 1917 He drew the final page towards him and wrote: Nov. 26, 1917. Discharged to duty. The story takes place in Edinburgh, Scotland. Nearly always at Craiglockhart. Craiglockhart is a mental hospital. Its a standard, boring hospital with long hallways. On every room there sleep two patients and there is door of a patients room that has a lock except the one of Sassoon. Not even the shower. The town itself is hardly described. The only things they talk about are the restaurants and pubs in a street. This is you room. Youre lucky; its the only one which has a lock. Plot Sassoon is against the war and is being send to Rivers to cure him. They talk about the war and why Sassoon doesnt want the war to continue. Sassoon wants to go back to the war to help his friends when he is cured. At the end he is inspected and declared fit and goes back to the front. Characters Siegfried Sassoon, Dr. W.H.R. Rivers, Billy Prior As reader, you follow Sassoon the most. Sassoons father left him when he was a child. He is against the continual of the war and writes poems about it. He was a very good soldier and hes being loved by his men. Hes been diagnosed as Shell-shocked. River is his doctor at Craiglockhart. Although he is against the war, he still wants to fight because he does not want to leave his friend behind. River is a doctor at Craiglockhart. His patients never have any physical problems, but always mental problems. By talking with his patients hes trying to find out why they are ill and he tries to help them recovering from it. Sassoon is a special case because he is not really ill. Hes just against the war, but they thought he was shell-shocked. Prior is a lieutenant in the military. Hes been send to Craiglockhart because he couldnt speak. He also suffers from asthma. Prior is difficult patient for Rivers because he doesnt want to talk about his memories of the war. He falls in love with Sarah, a girl who works in a munitions factory. They are main characters because these are the people who you constantly follow during the book. Sassoon: Sassoons the best platoon commander Ive ever known. The men worship him if he wanted German heads on a platter theyd get them. And he loves them. Being separated from them would kill him. Rivers: One of the nice things about serving afternoon tea to newly arrived patients was that it made so many neurological tests redundant. Prior: Prior reached for the notepad and pencil he kept beside his bed and scrawled in block capitals, I DONT REMEMBER. Nothing at all? Prior hesitated, then wrote, NO. Wilfred Owen, Anderson, Sarah Lumb, Dr. Lewis Yealland, Callan, Robert Graves Message As reader of the book you can learn what the effect of a war can haven on people. That it doesnt only gives a lot of casualties and wounded people, but also lots of men who get a nervous breakdown because of the things theyve seen and experienced. I think the writer wrote this story to let the people see and know what a tremendous impact war can have on people. Because war is not only about brave men fighting, but also about young men who die and get crazy because of what theyve seen. The message is conveyed to you through the patients. Every patient has a different disease, but all of them are caused by the war. Throughout the book you discover the reasons why they are ill and those reasons are arguments of why the war should not continue. After being thrown into the air and landing head first in the ruptured stomach of a rotting dead soldier by a shell, which causes him to vomit whenever he eats anything. B: YOUR OPINION I think Rivers and Sassoon are sympathetic. Rivers is sympathetic because he helps all the patients. He could also say: bye, Im not going to help you. Especially mental patients, because they require a lot of attention and time to cure them. Sassoon is sympathetic because he loved him man at the front and they loved him. He was a good leader and bomber. I want to help you, I really do. But in order to do so, youve got to corporate. Sassoons the best platoon commander Ive ever known. The men worship him if he wanted German heads on a platter theyd get them. And he loves them. Being separated from them would kill him. I disliked Dr. Yealland. I disliked him because he uses shock therapy to his patients and he even pushes lighted cigarettes to their tongues. The patient had been strapped to a chair for periods of twenty minutes at a time, and very strong electric current applied to his neck and throat. Hot plates had been applied repeatedly to his neck and throat, and lighted cigarettes to the tongue. Sadness and anger. I felt sad when I read about Burns who landed into the stomach of a dead soldier and the stories of the other patients. I was angry when I read about the methods Dr. Yealland used to cure his patients. After being thrown into the air and landing head first in the ruptured stomach of a rotting dead soldier by a shell, which causes him to vomit whenever he eats anything. The patient had been strapped to a chair for periods of twenty minutes at a time, and very strong electric current applied to his neck and throat. Hot plates had been applied repeatedly to his neck and throat, and lighted cigarettes to the tongue. Then the electrode was applied to the back of his throat. He was thrown back with such force that the leads were ripped out of the battery. Yealland removed the electrode. Remember you must behave as becomes the hero I expect you to be, Yealland said. A man who has been through so many battles should have a better control of himself. He fastened the straps rounds Callans wrists and feet. Remember you must talk before you leave me. Dr. Yealland is trying to cure Callan. Callan is similar to Prior. He cant speak anymore. Through electro-shock therapy hes trying to let him talk again. Hes willing to go on as long as needed. At the end Dr. Yealland manages to let Callan speak again. I think this is the best part of the book because its nearly the only part in the book where something really happens. Nearly everything that happens in the book is people talking with each other. This part has the most action of the entire book. I do not really to read about people talking with each other, I want action. Yes. The write succeeded to convey a message to me. I now realize how bad wars can be for those who fight in it and what the effects can be. The writer makes the message clear by showing all the patients who suffer from the war, which got traumas because of it. It shows you what the effects are. Yes. The message is very important. People must realize how horrible wars are so that we do anything to prevent them. A war will not only kill people physically, but also mentally. Have you ever had any mental problems because of the war? Have you been a doctor who worked with patients who have had mental problems? Why did you wrote the book? I would like to know the answers to these questions because Im curious why he wrote the book and how he got his inspiration, his stories of the patients. C: THE SUMMARY Part I 2 hours Sassoon is against the war. He wants it to stop. Because of that, the military authority has labeled him as shell-shocked. Rivers is a doctor at Craiglockhart. It is a mental institute. Rivers has his doubts about Sassoon coming to Craiglockhart, because he thinks Sassoon is not shell-shocked. Robert Graves is a friend of Sassoon. He thinks Sassoon should stop protesting against the continual of the war, because he cant stop it. Even though he has the same opinion as Sassoon about it. Sassoon wanted to get a court-martial, because then his opinions would in the publicity. But Graves manages to get Sassoon to Craiglockhart instead. When Sassoon meets Rivers they start talking. Rivers finds out that religion is not the reason why Sassoon isnt fighting. He has nothing against fighting. Sassoon has problems with the idea that while others are dying at the front, he is safe at Craiglockhart. At Craiglockhart there is also another patient, Prior. Hes not able to speak, but not physically. He communicates with Rivers via a notepad. After a while he manages to get River talking again, but he still doesnt want to talk about what happened in France. Part II 2.5 hours At Craiglockhart Sassoon meets Owen. Just like Sassoon he also writes poetry. He asks if Sassoon could sign some of his poems. When Sassoon finds out hes also writing poetry he asks to read his poems. Prior, another patient at Craiglockhart goes to Edinburg. There he meets a girl called Sarah. They start walking and at a graveyard they nearly have sex, but at the last minute she pushes him away. Because Prior wasnt at Craiglockhart during the night he was grounded for two weeks. Rivers wants to try hypnosis on Prior to retrieve some memories. It works a little bit, because he remembered how two soldiers in his platoon died. There arrives a new patient at Craiglockhart. Willard. He was injured to the spine while he was under heavy fire at a graveyard. He keeps telling that he cant walk because of pain in the spine, while there is nothing that causes it anymore. Sassoon and Owen start talking in Sassoons room. Sassoon gives Owen some poems to publish into the hospitals magazine. In exchange for that, Sassoon will mentor Owen on his poetry. Prior meets Sarah again in Edinburg. They take the train to the sea. They talk with each other about the war and what his function was in it. Suddenly a storm comes up and they have to take shelter into a bush. There they also have sex. Rivers is ordered to take a three week holiday because he is so exhausted from work. Part III 2 hours At Craiglockhart Sassoon helps Owen with his poem: Anthem for doomed Youth Sarah and her friend Madge got to a hospital to look up Madges fiancà ©, who is wounded. Sarah decides to walk around alone in the hospital and find a tent where are soldiers who are missing limbs. She is angry, because they hide these people away. Prior is being examined by a doctor. He is afraid that they will think he is faking his illness, so that he will be sent back to war. River is meeting some old friends. They are discussing about Sassoon. Rivers realize that Sassoon is free to think about the war he wants, but that it is his job to get Sassoon back to war. At the end, Rivers got offered a top job in London. Although its good for his career, he is not sure if he wants to take it. Burns is an ex-patient of Craiglockhart. He invites rivers to come to his house at the sea for a couple of days. Rivers expected that burns wanted to talk about the war, but Burns hadnt said a thing about it. At a night, there is a heavy storm. Burns walks outside and goes into a cave that floods a high tide. Rivers finds him there suffering from flashbacks of the war in France. When theyre safe home, Burns tells everything to Rivers about the war. Once back at Craiglockhart Rivers meets Bryce and tells him that he is going to take the job in London. Rivers has an appointment with Sassoon. Sassoon tells him that he sees hallucinations of dead friends. Sassoon feels guilty that he is not helping his friends at the front, so he decides that he should return to the front. Part IV 2.5 hours Sarah has told her mother about Prior. She is angry at her because she had sex so soon. She also doesnt believe in true love. Sassoon talks with his friend Graves. Graves thinks that Sassoon should not go back to war and that he must maintain his word. He also tells Sassoon that a friend called Peter has been arrested for prostitution. The military now sends Peter to Rivers to cure him because they think he is homosexual. Sarah works at a munitions factory. They talk about the war and Sarah asks why a girl called Betty is not at work. Lizzie tells her that she is in the hospital because she tried a home abortion using a coat-hanger. Rivers talks with Sassoon. In a while, Sassoon will be send back to France. They discuss about homosexuality and that especially during war the authority is hard against homosexuality because it does not benefit the soldiers. The medical board is reviewing a couple of patients at Craiglockhart to decide whether or not they are able to go back to war. Prior is send home and gets permanent home service because he has asthma. He doesnt like it because he thinks that the people will see him a coward and that he cannot find out what type of soldier he would be. Sassoon is tired of all the waiting before its his turn to meet the board, so he decides to leave and have some dinner with a friend. River is angry at Sassoon. Sassoon apologizes and tells River that he still wants to go to France. When Rivers is at his new job in London he meets his colleague Dr. Yealland. Dr. Yealland works very differently than Rivers does. He uses electro-shock therapy to cure his patients. When Rivers joins one of Dr. Yeallands treatments he is shocked by his methods and doubts whether he can work with him. Sassoon is send back to war and River is thinking about the effect Sassoon and last few months have had on him. I did not really had any expectations while reading. There was also not much to expect I think. They talk and thats it. Theres nothing thats going to happen of that someone is going to do something. The end ended as I expected it. Sassoon got back to war. But that is also what he always wanted and said he was going to do. I dont think there should be a different ending. I did not really liked the book. I prefer books with action in it. This book has nearly no action at all. Lots of dialogues and sometimes difficult language. In my opinion there were also no reasons to keep on reading. I can understand why there would be reasons for other people, but not for me. For me there were no things that I really wanted to know, so that I had to keep on reading. In overall I think it wasnt a bad book, but I also did not enjoyed reading it. I prefer different types of books.
