Wage Gap Assignment Example | Topics and Well Written Essays - 250 words

Wage Gap - Assignment Example From this study it is clear that the rate of white women and Hispanic women with some college education was similar at 18%. In associate vocational training, associate academic, masters and bachelors, the white women had a considerably higher rate compared to the other groups of women and more so the Hispanic women. All the groups of women had about a similar number of women undertaking professional degree and a doctorate at 1% each. White women had potential experience compared to black women, but at a higher rate than the Hispanic women. The white women percentage in rural areas was higher than those in the other groups of women. The white women had higher weekly earnings than the black women.This paper highlights that  the weekly wage gap between the white women and black women is $ 85 per week compared to $ 200.8 difference between the white women and Hispanics.   The decomposition analysis helps explain to what extend the wage difference can be explained by cited variables. From the earnings regression, we observe that High school dropout rate affects earnings per group of women, followed by high school graduation rates, having a doctorate and professional degree also caused the difference in the wage rate per group of women. The rate of part time employment also affected the wage earnings in the different groups of women.In conclusion, it may be noted that some difference between the white women's earnings and earnings for the other groups of women could not be explained by citing   the variables.

The audiences attention in a number of different ways Essay Example for Free

The audiences attention in a number of different ways Essay The opening scene catches the audiences attention in a number of different ways. Discuss how the playwrite, Willy Russell, has achieved this and whether he has been successful. The opening scene of Educating Rita is one that really catches the audiences attention in many different ways and to which some can relate to, be it through actions taken or through a characters attitude. The scene deals with and introduces the problems of both Frank and Rita, without going into depth over either of the characters troubles too soon. It is the instant clash of wit that catches the audiences attention. Russell also uses stage direction aswell as his characters personalities to keep information on these two characters flowing. He also uses symbolism as a further way of describing his characters without it being too obvious to his audience that hes letting on more and more about them. Act 1 scene 1 is the introductionary stage to Russells characters. In the first five minutes of this scene, we get to know Frank quite well. We learn that Frank is a university lecturer who appears to have grown tired of his job and the same old people. We see him searching the rows and rows of literature in his office for an author beginning with E; he then seems to decide he wants Dickens. Once he finds his collection of Dickens, he pulls them out, to reveal a bottle of Whiskey. We learn now that Frank also has a drinking problem. The phone then rings, just as Frank is about to take a swig of his Whiskey, and it turns out to be Julia, Franks girlfriend. They have a conversation that increases in venom until theres a knock at Franks door. Whoever is on the otherside of the door is having trouble making their way inside, and so Frank begins to get irritated with their posistant knocking after he has already said, Come in.. a few times. Eventually Frank hangs up the phone and Rita (actual name: Susan White. Likes to be called Rita after the author of Rubyfruit Jungle, Rita Mae Brown) bursts into the room. This womans behavior and language stun Frank, until they get talking and realize they get on well. Soon we learn that Rita/Susan (a hairdresser) has signed up for an Open University course, and Frank is to be her tutor. At first meeting, these two people appear to contrast greatly, but soon enough the audience begins to understand they have more in common than first thought. Frank is run down due to his heavy drinking, and his perception of the world is dim. He can no longer be bothered with his job, teaching the same old things, hearing the same old opinions and tutoring the same old people. His relationship with his girlfriend, Julia (an ex-student) is well and truly on the rocks, which the audience can tell from their frosty phone conversation at the beginning of the scene. Rita is also bored of her job. Shes bored of the same conversations with the same sort of people over the same sorts of haircuts. We dont learn about Ritas husband in scene 1, but things arent going well between them, like Frank and Julia. Denny believes Rita should stay home, take care of the house and every couple of years have a child, the usual behavior for a housewife in the 1980s; he isnt happy with Ritas choice of enrolling in an Open University course at all. In Rita, Frank finds the breath of fresh air both he and his job need, and in Frank, Rita finds someone to support and listen to her throughout her studies. Despite these similarities between the pair, there are still differences. Ritas idea of a classic novel is an erotic one (Rubyfruit Jungle) and her idea of a classic poet is Roger McGough. Franks main use for literature as Rita burst into his office is to hide his liquor, and he gave up on poetry long before Rita entered his life. Also, Rita is born-and-bred working class, whereas Frank is comfortable as Middle-class. This differ in social stature has an important effect on the language the two use and their accents. Still, nevertheless, the two click immediately. The stage directions at the beginning of scene 1 are very important, as through them we can fully imagine the setting of Russells play. We are told that the scene is set in a Victorian-built university in the north of England, so immediately we sense some class about the attendees of this place. We then get a description of the room, which is important as we understand the symbolism Russells uses right from the beginning. The book itself tells use about both the setting and the props used, but nothing about music or costume. In the film, directed by Lewis Gilbert, the music used is not something that could be found in the charts around the 1980s. Its a string piece that helps in setting the scene of a university where the students are more than happy to act a class above their own. But, we have to consider that even though the music used in the film was perfect for setting the scene for the theme throughout the entire play, its only one directors choice of music. The same goes for the costumes used in Gilberts production. The audiences attention is sub-consciously caught through Russells use of symbolism throughout the play. Franks office is a huge reflection on his own attitude. He hid his whiskey behind Dickens, and in real life he dodges the subject of his drinking problem with lines from classic literature. Also, nothing really has a place in Franks office, apart from his alcohol, also like real life. The more obvious symbolism used in scene 1 is Franks window and his door. His door can be thought of as the door to Frank himself. Its hinges are stiff, and so people have trouble getting past it, and always have done, but when Rita comes along, its different. The more Rita goes to see Frank, and comes into contact with this door, the easier it is for her to get past it. At first she oils it, but eventually theres no need for oil or force, it just opens. This is when Rita has broken through to Frank, and has worked her way through to his heart. This is something that no one has done before. Also, we could consider the door symbolism of Ritas entry to higher education. She desperately wants to study, but neither her mother nor her husband think she should. The trouble Rita has getting the door open could symbolize the last obstacle. From then on she struggles with this education, and with the door, but in the end she finds both easy to handle. The use of the window in Franks office symbolises a point in each characters development. Rita is ambitious to be like other students in the university, after she watched them from Franks window. She watches them, and asks Frank whether they could have a tutorial on the grass, but she fails to convince Frank of the benefits. The window, like Frank hasnt been opened for generations. Rita desires the breath of fresh air and wants to get educated. In contrast, Frank is more than content to remain isolated and remain in his insular office. I believe the opening scene of Educating Rita is very effective when capturing the audiences attention. The introduction of both characters traits, and how they react to each others opinions and personalities is both funny and moving throughout the play, but most interesting in this opening scene. This play also has underlying messages which make sense even nowadays, around 20 years after the play was written. Such as Ritas perseverance with her higher education instead of giving in to the stereotype of a woman at this time even though everyone around her (her mother and her husband) thinks she shouldnt be enrolling in her Open University course. In this respect, Rita is admirable, and shows that anything can happen to anyone if they simply keep at it. The audience simply must keep reading, as together Rita and Frank spark. Rita can study without judgement, and Frank is happier around Rita than he has been for years. These two characters gradually learn to help each other, and it is that element of their relationship that keeps the audience interested.

Pressure Groups vs. British Government Essays -- Politics Government U

Pressure Groups have become increasingly important in liberal democracies in influencing and raising awareness of their group’s particular causes or interest. This essay will assess wither or not pressure groups are more powerful than the government in Britain. To fully understand if pressure groups are more powerful than the British Government we much take into account the varying classifications of pressure groups, define what is meant by power, the different way pressure groups influence public option, the arguments for and against pressures being more powerful than the British Government and also the power government holds which pressure groups do not. The main argument of this essay is that although pressure groups do have some influence and power in today’s society but they are still not as powerful as the British Government. There are many different definitions of what a pressure group is Peter Lynch argues that a pressure groups is ‘Private, voluntary associations that wish to influence or control particular public policies, without becoming the government and controlling all public policy (Lynch, 2007, p. 245). Another definition is ‘Pressure groups are social aggregates with some level of cohesion and shared aims which attempt to influence the political decision-making process’ (Ball, A.R. and Millard, F, 1986, pp. 33-4). A final definition is ‘A pressure group is any organization that aims it influence public policy by seeking to persuade decision-making by lobbying rather than by standing for election’ (Coxall, 2001, p. 3).

Literacy in America Essay

America, the most technologically advanced and affluent of all nations on the earth, seems to have an increasingly larger illiteracy rate every year. This has become and continues to be a critical problem throughout our society as we know it. According to the National Adult Literacy survey, 42 million adult Americans can’t read; 50 million are limited to a 4th or 5th grade reading level; one in every four teenagers drops out of high school, and of the students who graduate, one in every four has around an 8th grade education. Why? You ask. This problem will never fix itself and will take quite a bit of time to overcome. We need to make sure that everyone is aware of the social problems, poverty and lack of family interaction that occurs everyday in many, if not all, communities throughout America. â€Å"Nearly a billion people, two-thirds of them women, will enter this world unable to read a book or write their names,† warns UNICEF in a new report, â€Å"The State of the World’s Children 1999. † UNICEF, the United Nations Children’s Fund, points out that the illiterate â€Å"live in more desperate poverty and poorer health† than those who can read and write. (Boaz). The most important factor that contributes to the outrageous statistics of illiteracy is that of poverty. Poverty is an issue that more and more of our nation’s children are coming face to face with and the price they must pay is unbelievably high. Poverty is considered a major at-risk factor (Leroy 2001). The term at-risk refers to children who are likely to fail whether it 2 be at school or life in general because of their life’s social circumstances. Some of the factors that may place these children at-risk are: dangerous neighborhoods; young, uneducated parents; unemployment; and inadequate educational experiences. Teachers need to be aware of the circumstances that their students face and be able and ready to help these children find a balance between the cultural values that they may have and values emphasized in school. By providing emotional support, modeling, and other forms of scaffolding, teachers can help students use their strengths, skills, and knowledge to develop and learn ( Marlowe and Page,9). The United States prides itself on being a free, democratic state. Jonathan Kozol’s essay â€Å"The Human Cost of an Illiterate Society† states that the United States is not the democracy it claims to be. For democracy to work at its best, a true representation of the common interests and how the majority feels about those interests must be in place. According to Kozol, about â€Å"60 million people in the United States are illiterate. † For the United States to be the self-functioning democratic state it proclaims to be, it has to be a literate society. The people of the United States are not part of a democracy without the full capacity to make informed choices, and furthermore cannot reap the benefits that a democratic society has to offer if the best interests of the majority are not represented. Direct quote #2 (Madison)with signal phrase. Hypo-thetical example James Madison wrote that a â€Å"people who mean to be their own governors must arm themselves with the power knowledge gives. A popular government without popular information or the means of acquiring it is but a prologue to a farce or a tragedy, or perhaps both† (Surowiecki, page 4). Voting is by far the most important aspect of a democratic society, and the percentage of people who do vote is a topic of much discussion here in the United States. If the number of people not voting is such a significant concern then the reasons they are not voting is 3 as well. An uneducated vote is not any better than a vote not cast at all. Imagine going to a voting booth and voting for a person or a ballot measure based on the ads you see on the TV only. In this circumstance, decisions are often made based on the negative ideas offered by both major political parties. If 60 million people in the United States cannot read, then they cannot cast a vote truly representative of their opinions. As Kozol claims, the United States has in fact become a government â€Å"of those two thirds whose wealth, skin color, or parental privilege allows them opportunity to profit from the provocation and instruction of the written word† (Kozol). The percentage of the population that is illiterate cannot choose which candidates make it onto the ballots, they cannot sign petitions, and they cannot choose which measures will pass or those that will fail. Direct quote #3 (Kozal), with signal phrase e. Of equal importance to a democratic society are the benefits that literacy provides to the public. When one is illiterate they are not able to reap the benefits of a free society. The freedom to choose enhances one’s chances of experiencing the best of anything. Illiteracy makes for a life of settling. An illiterate person has to settle for another’s interpretations of the world. According to the article ‘Democracy 101,† the ability to read opens a world that many people do not consider. The choice of where to live, what to eat, and where to work may all seem commonplace to the average literate person. Kozol uses the warning on a can of Drano in the opening of this essay to educate. It may take a moment for it to sink in but the reader will soon realize how much power reading and writing holds. Life, liberty and the pursuit of happiness are supposed to be guaranteed to all citizens of this country. Those that cannot read or write do not have the capability to choose who are the best people suited for ensuring those rights. Perhaps more importantly the 60 million illiterate people in this country cannot make the choices necessary to make use of those rights (Kozol).

10 Heterogeneous and Homogeneous Mixtures

10 Heterogeneous and Homogeneous Mixtures When you combine two or more materials, you form a mixture. There are two categories of mixtures: homogeneous mixtures and heterogeneous mixtures. Heres a closer look at these types of mixtures and examples of mixtures. Key Takeaways: Mixture A mixture is formed by combining two or more materials.A homogeneous mixture appears uniform, regardless of where you sample it. A heterogeneous mixture contains particles of different shapes or sizes and the composition of one sample may differ from that of another sample.Whether a mixture is heterogeneous or homogeneous depends on how closely you examine it. Sand may appear homogeneous from a distance, yet when you magnify it, it is heterogeneous.Examples of homogeneous mixtures include air, saline solution, most alloys, and bitumen.Examples of heterogeneous mixtures include sand, oil and water, and chicken noodle soup. Homogeneous Mixtures Homogeneous mixtures appear uniform to the eye. They consist of a single phase, be it liquid, gas, or solid, no matter where you sample them or how closely you examine them. The chemical composition is the same for any sample of the mixture. Heterogeneous Mixtures Heterogeneous mixtures are not uniform. If you take two samples from different parts of the mixture, they will not have an identical composition. You can use a mechanical method to separate components of a heterogeneous mixture (e.g., sorting candies in a bowl). Sometimes these mixtures are obvious, where you can see different types of materials in a sample. For example, if you have a salad, you can see different sizes and shapes and types of vegetables. In other cases, you need to look more closely to recognize this mixture. Any mixture that contains more than one phase of matter is a heterogeneous mixture. This can be tricky because a change of conditions can alter a mixture. For example, an unopened soda in a bottle has a uniform composition and is a homogeneous mixture. Once you open the bottle, bubbles appear in the liquid. The bubbles from carbonation are gasses, while the majority of the soda is liquid. An opened can of soda is an example of a heterogeneous mixture. Examples of Mixtures Air is a homogeneous mixture. However, the Earths atmosphere as a whole is a heterogeneous mixture. See the clouds? Thats evidence the composition is not uniform.Alloys are made when two or more metals are mixed together. They usually are homogeneous mixtures. Examples include brass, bronze, steel, and sterling silver. Sometimes multiple phases exist in alloys. In these cases, they are heterogeneous mixtures. The two types of mixtures are distinguished by the size of the crystals that are present.Mixing together two solids, without melting them together, typically results in a heterogeneous mixture. Examples include sand and sugar, salt and gravel, a basket of produce, and a toy box filled with toys.Mixtures in two or more phases are heterogeneous mixtures. Examples include ice cubes in a drink, sand and water, and salt and oil.The liquid that is immiscible form heterogeneous mixtures. A good example is a mixture of oil and water.Chemical solutions are usually homogeneous mixtures. T he exception would be solutions that contain another phase of matter. For example, you can make a homogeneous solution of sugar and water, but if there are crystals in the solution, it becomes a heterogeneous mixture. Many common chemicals are homogeneous mixtures. Examples include vodka, vinegar, and dishwashing liquid.Many familiar items are heterogeneous mixtures. Examples include orange juice with pulp and chicken noodle soup.Some mixtures that appear homogeneous at first glance are heterogeneous upon closer inspection. Examples include blood, soil, and sand.A homogeneous mixture can be a component of a heterogeneous mixture. For example, bitumen (a homogeneous mixture) is a component of asphalt (a heterogeneous mixture). Not a Mixture Technically, if a chemical reaction is occurring when you mix two materials, its not a mixture... at least not until it has finished reacting. If you mix baking soda and vinegar, a chemical reaction occurs. Once the reaction has finished, the remaining material is a mixture.If you mix together ingredients to bake a cake, a chemical reaction occurs between the ingredients. While we use the term mixture in cooking, it doesnt always mean the same thing as the chemistry definition.

The American Dream Essay

The American Dream Essay Free Online Research Papers What is the American Dream? There has always been a dream in the hearts of man that the American Dream is the one goal in life that all must pursue in order to achieve something in their lives. Although the American dream has always been present, the one time that the American dream had its time of reward to the American people was after the Great War, during the 1920’s. Known as the Jazz Age, this time period was a social, psychological, and material flourishing of the American people that has been classified as a time of immense opportunity. The Jazz Age was important to the American dream because it shows the different aspects of the exact rewards and consequences of following it. During this time of cultural prosperity, many novels had portrayed American society as a lost Eden, the land that has lost its identity from the degradation of human values. The myriad of works being published during that time period depicts the downfall of the American hero. In the novel, The Great Gatsby, a man, Jay Gatsb y, attempts to pursue the dream for of a perfect life, but his goals eventually backfire upon himself. In the work, A Raisin in the Sun, a world of seemingly endless opportunity is seen from the perspective of an African American family. In Hemingway’s A Farewell to Arms, a disillusioned man tries to escape the odds against him in war by running away but still loses everything. Although the American dream defines America as a â€Å"New Eden† of ever-expanding opportunity, the seemingly self-reliant individual will become disillusioned to the fallacies of America and come to the truth that its dream is neither true nor attainable despite the efforts of the individual. While many believe that America is a land of purity, the wastelands that the uninhibited pursuit of material wealth elucidates that the effects of the American lifestyle are not boundless but only hidden. The affluent lifestyles of the Jazz Age initiated a decline in morals and the disruption of society. The lifestyles made the impression that a living could be made instantly and anyone with a vague want for success could fulfill all of their desires. Gatsby, an outcast exploited by society, follows such a dream, but falls from grace into a common quagmire, thus preventing him from achieving his American Dream. The society, in its hunger for success in the form of the American dream, took what Gatsby had to offer it in the form of numerous parties but gave nothing in return when he was in need and in fact condemned him as a scapegoat when a murder had been committed. In the novel, Gatsby’s personality and desire â€Å"turned out all right at the end†¦ it is what preyed o n Gatsby†¦ [,]what foul dust floated in the wake of his dreams† that killed off his dreams, passions, and goals (Fitzgerald 6). In the novel, an important symbol is the ash heap, which represents the sins of humanity and the faà §ade of the American dream. The ash heap represents the unintended consequences of the unrestricted lifestyle of the American dream. The purity of the American native land was at first pristine and full of potential. However, the lifestyle of abusing the land for individual ends corrupted the opportunities that the â€Å"old island here that flowered once for Dutch sailor’s eyes- a fresh, green beast of the new world [‘s] vanished trees that had made way for Gatsby’s house† was destroyed for the riches of the American Dream (189). The Dutch Sailor’s were people who had seen America as full of potential and became the aboriginal settlers that cultivated the vast opportunities that America had to offer. Jay Gatsby was a man that did not have the realization of his dream. He was so stuck in the past that he did not realize that the people around him were not going to comply with his rules. He wanted so much from everyone and thought that he controlled every aspect of his life. As he fought on for the attention of Daisy Buchanan, his lost fiancà ©Ã¢â‚¬â„¢ and the last key to his American Dream, he never realized that he was going to die before he could reach his fullest potential. The sin of society prevented him from achieving what he truly had aspired to do. As Nick Carraway, the narrator, states, â€Å"we beat on, boats against the current, borne back ceaselessly into the past†(Fitzgerald 189). Fitzgerald’s cynical view of the status of things shows that no matter how hard someone tries to achieve the American Dream, there will always be obstacles to the dream that will cause them to be pushed back to where they had begun. The idea of a perfect American Dream will undoubtedly cause one to end in disaster. Without the disillusionment of reality, one who pursues this dream of the perfect life will not progress in life because of the innumerous odds against one. The American Dream is a solution to the individual’s problems as it is based on the actions of the individual, but even if the individual does all that he or she can to accomplish it. There are innumerable odds that go against the will of any specific person that there are absolutely no chances for someone to achieve the American Dream. In the novel, A Farewell to Arms, by Ernest Hemingway, a man named Frederic Henry attempts to receive the glory of the war, but is eventually disillusioned to the war and tries to run away and escape the perils of preordained death of a soldier. He gives up and tries to make a new life with a girl named Catharine Barkley. She was the connection and the anesthesia for him to forget the war. However, he does not make out of the war without a scratch. He ends up losing both his son and Catharine to a failed childbirth. This shows that the American dream is impossible to attain because the entire world is against the individual in any of his or her goals. Hemingway’s philosophy is that one must be of much bravado and strength in order to survive in this world. Although, he believes that there are no ways that someone can succeed because they will either die or die fighting. The hopelessness of Hemingway is characterized by the words of Ferguson who gives the advice that Henry would â€Å"never get married†¦ [And that] You’ll die before you’ll marry†¦ Fight or die. That’s what people do. They don’t marry†, which is a pessimistic view of a woman who does not approve of the relationship between Henry and Catherine (Hemingway 108). This foreshadowing is correct as they do not marry, but he does not fight as he tries to evade this prophecy. He runs away but Catherine has taken his place and left him alone anyway. Either way, he will lose everything that he had worked for. This shows that the American dream really is not attainable. There are so many odds that against someone tha t they will end up with the short end of the stick either way they choose. In the war, the soldiers become very pessimistic about the war. They start to doubt the world that they live in, and they become frustrated at why the war won’t ever end. One soldier, named Passini, muses that war â€Å" doesn’t finish There is no finish to war. . War is not won by victory†¦ One side must stop fighting†, but there are always people fighting because if they stop, the other side would kill the survivors (Hemingway 50-51). This shows that society is always against the individual when he or she tries to commit to something. The war illustrates what people will become when they are exposed to a world in which the only goal is to stay alive. However, the true goal is to push everyone else down to stay alive. Therefore, a life with the American Dream is not possible because there will always be those that do not care for equality and make the dream impossible for anyone in cluding those at the top. As we fight each other in a war, the entire purpose of life is nullified to becoming pointless. The entire American Dream is stated in the novel of Hemingway as a moral that people can try to escape but they will always be beaten down. The novel shows how the American dream is not only unattainable but is also unavoidable because there are no other choices besides fighting and dying. When people believe that America is a land of opportunity to start anew and begin a life that will automatically bear fruit from simple schemes and tricks, rather than work hard and try go stay alive, their pursuance of their fictitious dreams usually end up in disaster and the only remedy to alleviate these circumstances is to stop following the American dream and start without any remnants from the past life. While Henry brought along his love to start anew, he lost that because it was from the war. In A Raisin in the Sun by Lorraine Hansberry, an African American family tries to make a living despite the constant pressures and concerns over money. After the money is lost in a gamble, the family makes a downward spiral into the collapse of moral values. The greatest change comes from the man, Walter Lee, the father of the African American family, as he finally embarks on a journey from being a self-hated man who did not have a good job to the full acceptance of his role as the fath er and leader of the family. The greatest moment of truth that occurs in the movie is the time that Walter Lee rejects the offer of money to ruin his family. Earlier, he would have accepted the offer; however, at this time Walter Lee became a man and did not care for money as much as he did before. He believes in the instant wealth dream. He desires to invest in a liquor store, which is reminiscent of the 20’s in which men had bootlegged for extremely large sums of money. The help that he receives that makes him change his ways as the scolding of his mother who states â€Å"freedom used to be life† after he ignorantly replies â€Å"it was always money†¦ We just didn’t know it† but as he says this, he learns that he is at a crossroads between his morals and the things that he has learned about the modern world (Hansberry I.i.73). However, when he loses the money to a thief who he entrusted his savings to, he learns that acceptance of one’s posi tion is more important than receiving monetary compensation. He stops his ways and changes into a better man. The man here changes from avoiding the American Dream. He only escaped the continued wrath of the American dream because he had given it up for a simpler life with his family. However, when he stopped trying to take for himself the limited resources of the family and becomes obsessed with material wealth and money, he lets go of the personal values of respect to his family that he was taught by his mother. The belief that there is an unlimited amount of opportunity in this world will lead someone to give up anything to get at the prize because the rewards would hypothetically save him or her from losing everything. The fear of not attaining the American dream causes him to make rash judgments. By however, as insidious as the world is, people will get swindled for their belief in the perfect life and will end up by losing their hard earned savings rather than working hard to make a living for those around them. However, he is wrong when the dreams are already dead. Walter does not consider the hope of Beneatha to save the family when he uses the money in a selfish way. Beneatha cries out after a Walter’s mistake â€Å"we are all dead now†¦dreams and sunlight [is] all dead now† (Hansberry I.i.143). This shows that there were dreams already. However, the American dream of Walter changed those of the entire family. The hopeful dreams of Beneatha show that there is still hope for the family. The greed of the American Dream causes Walter to stray from the path; potentially ruining the family and setting the family back a generation of savings. The family changed back to the original dream before there could be much more damage done from the pursuit of the fake American Dream. As Gatsby did, Walter was trying to go into the liquor business. As a bootlegger, Gatsby achieved much wealth in a short amount of time. However, as quickly as he had attained the money, he had lost it. . However, the society that he rose out of made him go back to where he had started in the first place. In order to make any progress at all, Walter and Gatsby should have ignored the American Dream in order to save their money rather than make schemes to make it fast. When someone becomes disillusioned to the materialistic desire of the American Dream, he or she will be able to accept his or her own place in this society more. Thus, there is still hope in the fact that there are other dreams that do not pertain to the preconceived notions that create the American dream. Without the thinking that America is perfect and that there are no risks and consequences to the unrestricted life of desire and going against a world that will crush all those that try to go against accepted morals and societal values. The American Dream is a dream that many people believed in and still do. However, when they become disillusioned, they realize what kind of mistake they have been making. The mistakes are to believe that the three false factors that constitute the American Dream: The belief that America is a â€Å"New Eden† that is pure and has unlimited resources, that progress is important and the opportunities available in America are endless, and that individual self-reliant individual can achieve success without considering the truth of a corrupt and failing society. Thus, the reality of a bold new future will awaken to those who understand the workings of America. They wish to take on the power of heroes, but in reality they are nothing to the immeasurable forces, which act against them. The belief that America is a land of heroes is false. There are no perfect dreams. Just as people try to achieve the most and become the greatest success they can possibly be, the American Dream is impos sible to achieve. Just as Gatsby had tried to accomplish, people will attempt to force their way to the top but as they do, people already at the top would push them back down for fear of losing the money they had already gained. The immeasurable odds are against the individual and the pursuit of the American dream is pointless and will only end up either in death or destruction from fighting it. The only way to live a prosperous life is to accept the life that one has and not risk themselves for a fake dream that applies to none whom pursue it.

Educational Article A Better Way to Understand Teams and Roles

Educational Article A Better Way to Understand Teams and Roles Read about what a team is, what Belbin team roles are and how to make the work in a team effective. Team interaction and management is a core discipline in HRM studies and is a critical area of competence for any manager. The success or failure of the entire organization is dependent on how effectively the people within it  can work together. Of course, any management task involving people can be a little confusing, even messy; people do not neatly fit â€Å"models† and prescribed solutions, and the challenges only grow as people are brought together into purposeful groups. In this article, some of the well-known important concepts of teams and the roles people play in them are presented to show how popular academic ideas are reflected in real life, and what approaches can be taken when people in teams – as they inevitably will, pretty much all the time – do not behave in quite the way our textbooks and lectures lead us to believe they should. Assigned to write a management essay? Learn what a management essay is: MANAGEMENT ESSAY What Is a Team? That sounds like a simple question with an answer that everyone should understand without a lot of mental exercises, but the â€Å"team† in â€Å"team management† is more often than not treated casually, or overlooked entirely. An effective team is not merely â€Å"a group of people working towards a common objective but a community of practice, which has three â€Å"crucial† characteristics domain, community, and practice. Dr. Etienne Wenger Domain.  The shared domain of interest – in a work team setting, this would usually be the â€Å"purpose† of the team – gives the group a distinct identity, which may or may not mean anything to anyone else. As an example, Wenger describes how a street gang’s identity as a unit is formed by the shared domain of its individual members, even though that is ultimately probably not in their best interests or those of civilization as a whole. The key to the idea of â€Å"domain† is learning: what starts out as just a common interest among individuals is refined and increased by learning through interaction. Community.  A community is characterized by joint activities and shared information, which contributes to the shared learning. The distinction between â€Å"community† in common sense – such as a neighborhood, or a group sharing a common topic of interest on a Facebook page – and community in the sense meant by Dr. Wenger is subtle and perhaps difficult to understand. It is easier to think of it in terms of where the intended benefits of the team interactions are focused by the team members; if the intention is an individual benefit, then the team is probably not a true community. For example, a neighborhood might not be a true â€Å"community† (although we may call it that), if whatever â€Å"neighborliness† practiced by the residents is primarily motivated out of self-interest for their own security and comfort. Practice.  What differentiates a â€Å"community† from a mere â€Å"group† is shared practice, or as Dr. Wenger describes it, a shared pool of intellectual resources – stories, tools, experiences, and ways to solve recurring problems. A group of truck drivers trading stories over coffee in a truck stop are not simply being friendly and entertaining themselves, but are actually building a knowledge base and learning from one another. See also:  Managing Problems in Groups Dr. Wenger, who is a social learning theorist with a background in Artificial Intelligence, implies that a â€Å"community of practice† is the most effective when it forms organically. This actually makes sense, because the motivation both in having an interest in the first place and then in pursuing it is largely intrinsic. Talk to any random truck driver, for instance – it’s nearly impossible to find one who doesn’t actually like being a â€Å"trucker†, in spite of whatever day-to-day annoyances might be encountered. But knowing how effective team works as a â€Å"community of practice† does make it possible to form the team purposefully, so long as the team members chosen individually have two basic traits: Commitment to a common interest or aspiration, as long as it is a specific interest or aspiration. If the goal for the team is to develop a world-beating software application, then the people chosen for the team should be passionate about developing software; enthusiasm for the vague aspirations expressed in the company’s Mission Statement or enjoying â€Å"working with others† is not enough, nor particularly relevant. Good communication skills, or specifically, the ability to coherently communicate the passion for the common interest in practical terms. This also applies to being able to interpret others’ ideas. Naturally, finding the passionate, communicative people to build a team is only part of the puzzle; they still won’t be able to accomplish anything if they do not have clear roles to play. Roles in Teams. Belbin Team Roles A popular – and to be fair, not altogether useless – theory that one will encounter at some point in management studies is the Team Role Theory of Dr. Meredith Belbin. Dr. Belbin’s research led him to develop a description of nine roles in teams, which should be represented in a balanced way for the team to be effective: According to Belbin’s website (the theory has become, not surprisingly, the basis for a multi-million dollar consulting business), the behavioral analysis that determines what individuals’ team roles should be â€Å"Can be used to build productive working relationships, select and develop high-performing teams, raise self-awareness and personal effectiveness, build mutual trust and understanding, and aid recruitment processes.† The theory is backed up by empirical research, and does, in fact, give insights into how people work in teams, but only after the team has been formed and interacts for a period of time  when roles and attitudes begin to emerge because Team Role Theory has two big flaws: 1. GENERALIZATION   some people are predictable, but most are not. The context of the team and the actual objectives the team is trying to achieve have a much greater part in determining how team members will act than the theory allows, because the roles themselves were developed from statistical results; results that furthermore did not allow for people to have aspects of more than one â€Å"role† in their personalities, which most people do. 2. OVER-THINKING   in any team, as a practical matter, there are only four roles that need to be filled: The Team Leader (organizes the team and keeps communication flowing smoothly) The Record-Keeper (keeps track of what the team is doing) The Worker (accomplishes the tasks the team needs to complete) The Progress-Chaser (conducts follow-up, testing, and monitors progress against the expected schedule) What Team Role Theory can do to help – and why it is important to study and understand it, though it is not as practically useful as advertised – is to give some insights into what roles, and to what degree of those roles, prospective team members are best suited to fill.

Human Resource Management strategy Essay Example | Topics and Well Written Essays - 1000 words

Human Resource Management strategy - Essay Example The concept of Strategic Human Resource Management has replaced the traditional perception of human management. Even though the traditional theories of human management (Maslow's hierarchy of needs, ERG theory and Herzberg Two-Factor theory) are still used by most of the HR managers, the functions have changed to include the strategic planning. Human Resource Management can build the organizational capacity and sustained competitive advantage. Organizations must be able to adapt to the changing environments and be ready to react to risks. Any organization that wants to remain successful must continually assess and formulate new strategies to meet the needs of its customers (both internal and external) in more effective ways (Marchington 2005). For example, if the organization is emphasizing the cost strategy, the changes in HRM activities will enable those strategies to become the major focus of organization. If particular, the multi-skilled employees and less expensive staff will help to meet the cost objectives. Without proper changes in HRM functions, organizational strategy might fail. Not a single organization is able to avoid conflicts and risks on the market. The development and application of the HR strategies of dealing with conflict determine the way company will deal with the outside conflicts. There are three HR views on dealing with conflict: traditional (conflict is harmful and requires the firm approach for avoidance), behavioural (conflict should be expected and turned into benefit), and interactionist (conflict is inevitable and should be challenged). These three views represent the ways companies are dealing with conflicts within organization, in the workplace setting. However, the same views can be applied to strategic management as well. For example, there is always the threat of competitor being more successful in marketing and if the company is ready to face this challenge, it can be turned into the benefit. Moreover, companies spend thousands of dollars to recruit talented employees and pay bug salaries to the individuals who contribute the company's success. At the age of globalization and increasing importance of skillful workforce, retaining employees is not an easy task and has become the part of the strategic planning. Employees, especially upper level, should be motivated not only to remain with the company, but also to improve their performance on continuous basis. As the research indicates, the Maslow's hierarchy of needs was not validated, but it does work in motivating employees (Purcell 2003). It is worth to note that the strategically important employees come into the company when the needs of the lower levels are already met and they seek for self-actualization mainly. Motivation of employees, as it was already noted above, is the key factor in achieving the company's success. Herzberg's Two Factor Theory provides the insight on motivators and dissatisfiers. Herzberg assumed that motivators are under the control of individuals, while dissatisfiers are under the control of organization. However, this assumption does not seem to be workable. For example, if the HR Managers knows about the factors which satisfy the employees and motivate him to contribute more into the company, these factors could be stressed continually. Thus, motivators are un

English Composition - Essay Example Now I understand that gay marriages are to be considered an essential human rights issue. It could raise the social statues and economic stability of the sexual minority of gays and lesbians. The civil rights aspect of it stems from the question of equality for all individuals. Homosexuals have to be treated on an equal basis in the socio-cultural sphere, and be provided equal opportunities to participate in all possible areas of public domain. The narrow-minded arguments against it by religious sects and homophobes have to be addressed and disproved so as to defend the basic rights of homosexuals. One may need to redefine the parameters of family structure to accommodate gay marriages, but that will only strengthen the possibilities of tackling the issues of dissent in the general social structure. A few of the controversial issues related to gay marriages have to be addressed and analyzed to make this view clear. The real reasons behind the arguments against gay marriages go deeper to the levels of ignorance and lack of proper understanding among human beings. Many are misinformed regarding the nature of gay relationships and consider it as something entirely different from heterosexual relationships. Gay relationships are often perceived to be all about sex, but that is hardly the issue. The reality is that homosexuality is based on mutual attraction, love and affection, very much like in the case of heterosexuality. If the commonly held misconceptions regarding gay relationships can be eradicated, the prospect of gay marriages can be understood clearly. The false presumption that a marriage can take place only between a man and woman has to be uprooted. Nor does one have to fall for the argument that the basic purpose of marriage is procreation. The element of immorality attached to gay relationships is also

Agile Port System Essay Example | Topics and Well Written Essays - 500 words

Agile Port System - Essay Example Older ports have to get into alliances and partnerships to coordinate their activities and decrease unnecessary competition. These alliances can lead to the creation of satellite terminals instead of the presence of several redundant old ports. This can help reduce congestion of containers at deep-sea ports and free up space for high-cost facilities in such locations. Through alliances, there can be the better exchange of information, which reduces dwell-time and improves movement (Konings, Priemus and Nijkamp, 2015). Exchange of valuable information helps in security checks and value added logistics, and this is only achievable through partnerships for the common good of making profits. In relation to technology, fast and real-time data processing and sharing are essential for the expansion of infrastructure and superstructure. This is essential to facilitate tracking and tracing of shipments. For example, the Electronic Data Interchange information system can help in recording and sharing of information across ports. Efficient coordination between terminals and inland transportation operations is applicable if older ports adopt modern web applications and systems to facilitate the dynamics of terminal handling operations. In addition, older ports should improve gate operations technology to improve processing time in gate lanes. Construction of dedicated lanes is also essential to save time and improve functionality. In conclusion, several areas mentioned above require improvement to adapt an agile port system.

Government - Essay Example In spite of the deliberate effort to keep political parties out, the United States was the first nation to have formally recognized political parties as far back as in 1800. These political parties gained executive powers through elections, and in thirty years political parties were an indispensable part of the American political system. A political party has been defined as â€Å"an autonomous group of citizens having the purpose of making nominations and contesting elections in hope of gaining control over governmental power through the capture of public offices and the organization of the government† (Hukshorn, 1984). Presently, there are two main political parties in the United States -- the Republican and Democratic parties. All elected representatives, whether they be president, congressional representative, state governor or state legislator have to members of either of these two parties. There is no denying the fact that the two-party system in the United States has emerged as a result or reflection of the desire of the electorate that is the people. In other nations of the world which have a two-party system, each party represents conflicting ideological perspectives. In the United States, however, the two parties have tended not to adhere strictly to any one ideology or policy objectives. â€Å"Generally, Republicans have tended to support limiting federal powers and protecting the authority of state and local governments, to take a conservative approach to taxation and spending, and to oppose government interference with free enterprise. In contrast, Democrats have tended to take a more expansive view of the powers of the federal government, to support raising and spending money to address social ills on a national basis, and to favour federal regulation as a tool to improve business practices† (Bibby, 2004).

The tate gallery - Essay Example This is where marketing comes in handy. Marketing is a very important function of any business. Marketing involves identifying the customer needs and then making products that will satisfy those needs (Kotler et al 2007). Marketing is very important and beneficial to all the parties since the consumer will be provided with the goods he or she needs while the producer or seller will sell most if not all of the products since the products are produced as per the demand (Scott, 2008). The Tate Gallery uses marketing in advertising its artwork. They send out staff that studies the market and then brings the results. An area of study could be: prevailing conditions in the market (Kotler et al 2006). The Gallery then advertises those artworks which are most likely to attract the attention of the public. The artworks could be those that represent the current situations faced by various countries or the world in general (New York Times, 2009). The public’s curiosity will be stirred and they will want to see more of what the art Gallery has. This will draw more customers to the Gallery (Chamot et al 1964). Marketing is characterised with the marketing mix which is also commonly referred to as the 4Ps (Kotler et al 2007). These Ps include price, place, product and promotion. Price is that amount that is charged on a product. Price is determined by factors such as buyers perception of the value of the product, costs of the raw materials, level of competition, market share etc. Product is defined as that object or service that is produced in large numbers. Examples of products are the art paintings, sculptures etc. Examples of services are the hotel service, tourism etc. Place is the site at which the product is bought; the place maybe a physical location or a virtual location. Promotion is the means through which the marketer communicates any kind of information that will help him or her in his or her job. There are four major aspects

Seven Steps to Project Planning Essay Example for Free

Seven Steps to Project Planning Essay Seven Steps of Project Planning April Willochell Project Management Every project is an opportunity to produce something new, to make a real difference. You can introduce change, increase productivity, enhance capabilities of your company or of a client or build new relationships. Seven steps are essential to success in organizations that simultaneously manage multiple initiatives. Effectiveness begins with good pre-project planning plus an understanding of what a project is and what can be at stake. Consistently following these seven key steps can directly improve a company’s operations, profitability and sanity. The first step is a setting goals phase. â€Å"During this stage the teams responsible for the project are assigned and a brief is provided containing information on what the project hopes to achieve and what approach will be taken to complete various actions required. Additionally, this stage usually leads to the appointed of a project manager and executive in charge who with the help of the team start to plan the next step. † (7 Steps, 2013) In this stage all stakeholders should state their needs and how they would like them to be fulfilled. Ultimately, this is the goal setting phase. The next step would be initiating the process. This means that a team would be assembled and the overall project is outlined to detailed specifications. This includes strategic planning, like how long the project will take, how many steps will take place, and what tools will be needed to execute the project. Deciding how the project will be controlled is the third step. This step is also called directing the project. This means that the organization that is controlling the project is defined. Also, all organizations within the company that will be involved are determined. This part of the planning process will determine who receives reports and makes final decisions in the planning process. â€Å"This step is about developing a Work Breakdown Structure (WBS) that identifies the low-level tasks and activities required for doing project work and producing the deliverables. The WBS is a critical piece of the project planning process because it defines how tasks will be structured and what dependencies will be created. It is also used for setting up urations, task assignments, resource requirements, and cost estimates. † (The Planning Process, 2013) The control stage is the fourth stage. â€Å"You must develop a project strategy that follows the mission and outlines the high-level actions for implementing the project objectives. You must develop a project strategy that follows the mission and outlines the high-level actions for implementing the project objectives. â⠂¬  (The Planning Process, 2013) This process will let the team know who will need to sign off for what processes in the project. This stage will also let the team know where potential problems may arise and if they do how they should be dealt with. This stage is very important in the planning process. The fifth stage of project planning is setting up boundaries for each stage of the project. This is basically setting up deadlines for each stage of the project. If a stage is not met, there also needs to be backup plan on how the plan will play out in this event. This stage also determines how each stage will close and the steps following that closing. â€Å"The penultimate stage is the management of product delivery. In this step the project manager works with team managers to ensure that a set of formal requirements are created for every piece of work contained in the project. Essentially if this is done correctly all of the work should be delivered on time and to a suitable standard. † (7 Steps, 2013) This sixth stage is to make sure that all paperwork is in order, the project and its product follow all regulations, and all parts are in working order. This is basically, a quality control stage. The seventh and final stage is the closing stage. This step is the risk management assessment part of the planning process. Project managers and their teams must identify all the risks in their project and discuss the alternatives. The plan will be reviewed, discussed, and any potential changes will be made. Once all seven steps are followed accurately a project plan should be planned perfectly and executed just as well. Resources 7 Steps to Project Planning.

Performance Of Wells Turbine Engineering Essay

Performance Of Wells Turbine Engineering Essay ABSTRACT A Wells turbine has inherent disadvantages in comparison with conventional turbines: relative low efficiency and poor starting characteristics. In this case, the performance of wells turbine is studied on computational analysis by changing aerofoils and providing different angle of incidence for the improvement of the turbines performance. Study is based on analysing the flow of air on turbine using computational analysis at steady condition. 1 INTRODUCTION: The Ozone depletion and global warming have altered the international community and urged the need for more focus on alternative green sources of energy. Ocean wave energy is one of the renewable forms of energy which can be utilized in response to the disturbing prospect of an exhaustible source of energy. Several wave energy devices being studied under many wave energy programs make use of the principle of the oscillating water column (OWC).Potentially; the most successful device used in harnessing on wave energy has been the OWC wave energy converter. The OWC chamber, either floating or bottom standing, with the immersed end opened to the action of the sea. A reciprocating airflow is created by the action of the free surface of the water within the chamber. The conversion of this airflow into mechanical energy may be achieved by a number of devices like:- A. TAPCHAN: The TAPCHAN comprises a gradually narrowing channel with wall heights typically 3 to 5 m above mean water level. The waves enter the wide end of the channel and, as they propagate down the narrowing channel, the wave height is amplified until the wave crests spill over the walls to a reservoir which provides a stable water supply to a conventional low head turbine. The requirements of low tidal range and suitable shoreline limit the world-wide installation of this device. Fig (a) TAPERED CHANNEL[1] (TAPCHAN)http://re.emsd.gov.hk/english/other/marine/images/marine_tech_010_2.gif B. PENDULOR: The PENDULOR device consists of a rectangular box, which is open to the sea at one end. A pendulum flap is hinged over this opening, so that the action of the waves causes it to swing back and forth. This motion is then used to power a hydraulic pump and generator.http://t2.gstatic.com/images?q=tbn:ANd9GcQ7yge9ouptnhszDgsXGA_gCvAXKqbo78BeXZHFFtPB89433p0p Fig (b) PEDULOR [2] C. WELLS TURBINE: The Wells turbine is one of the most suitable air turbines for energy conversion from oscillating air flow. . A schematic view of the OWC device with a Wells turbine is shown in Fig. c. The Wells turbine is an axial flow air turbine. It consists of several symmetrical aerofoil blades set around a hub. As waves Impinge on the device, they cause the water column to rise and fall in the air chamber, which alternately compresses and depressurized the trapped air. This air is allowed to flow to and from the atmosphere through a turbine which drives an electric generator.http://www.aussiestockforums.com/forums/attachment.php?attachmentid=9213stc=1d=1180172232 Fig (c) WELLS TURBINE[3] Fig. 1.1: Schematic of the Three Major shoreline Devices The Wells turbine is a self-rectifying air turbine which is expected to be widely used in wave energy devices with the OWC (Raghunathan, 1995) .It can extract power at low airflow rate, when other turbines would be inefficient. The Wells turbines for wave power conversion have less efficiency. To increase the efficiency is the major quest all over the world, the flow of air through the wells turbine impeller is carried out in this project by using different size impeller and introducing biplane i.e. two rows of symmetrical aerofoil blades. 1.1 WAVE RESOURCEShttp://www.oceanenergy.ie/images/world-map.jpg Fig. 1.2: Global Distribution of Deep Water Wave power levels in kW/m crest length[4] Despite the climate change phenomena, the world resource for wave remains very much as shown in fig. 1.2 by Dr Tom Thorpe [5]. The highest energy waves are concentrated off the western coasts in the 40o-60o latitude range north and south. The power in the wave fronts varies in these areas between 30 and 70kW/m with peaks to 100kW/m in the Atlantic SW of Ireland, the Southern Ocean and off Cape Horn. The capability to supply electricity from this resource is such that, if harnessed appropriately, 10% of the current level of world supply could be provided [4] PERIOD AMPLITUDE POWER DENSITY VELOCITY (m/s) WAVELENGTH (sec) (m) (kW/m) (m) Storm 14 14 1700 23 320 Average 9 3.5 60 15 150 Calm 5.5 0.5 1 9 50 Fig: 1.3 Tthe nautral and technical wave energy resource for the north and west side of the UK[6] The techinical resource is dependent on the nautral conditions like the shape of the rock and location i.e beaches and gullies. The wave energy at calm sea is considered in this project. 1.2 WELLS TURBINE The monoplane Wells turbine i.e. the basic Wells turbine consists of several symmetrical aerofoil blades (NACA four digit series) set around a hub at 90 degrees with respect to the airflow. Since its an invention by Prof. A.A. Wells in 1976, most researchers have focused on improving its efficiency and its range of efficient operation. In fact, compared to other conventional air turbines (e.g. Francis turbine) the Wells turbine has a lower efficiency and a narrow operational region. Nevertheless, it can extract power at low airflow rate, when other turbines would be inefficient. Fig. 1.4: Schematic of the Monoplane Wells Turbine[7] A schematic diagram of a Wells turbine is shown in Fig. 1.4. At first sight the arrangement might seem to be unlikely means of energy conversion. However, once the blades have attained design speed the turbine is capable of producing a time-averaged positive power output from the cyclically reversing airflow with a fairly high efficiency. Wells turbine has low efficiency and poor starting characteristics. The Biplane Wells turbine: Muhammad Mamun in the Study on the Hysteretic Characteristics of the Wells Turbine in a Deep Stall Condition says the pressure drop across a mono-plane Wells turbine above is proportional to the square of the tip speed which has to be limited if transonic effects are to avoided. For wave energy devices which produce significantly larger pressure drops than the limit for a single plane turbine a biplane turbine can be used Fig. 1.5: Schematic of the Biplane Wells [7] It has certain advantages over the conventional monoplane Wells turbine as follows: I. It can operate under high loading. II. It can absorb higher wave power than the monoplane turbine if the diameter and rotational speed of the turbine are kept constant. III. The design speed is lower than that of the monoplane for the same loading. IV. It avoids the use of guide vanes and therefore the turbine would require less maintenance and repairs. [7] 1.3 PRINCIPLE OF OPERATION The principle of operation of Wells turbine is based on the classical aerofoil theory. According to the classical aerofoil theory, an aerofoil which is set at an angle of incidence ÃŽÂ ± in a fluid flow generates a lift force L normal to the free stream. The aerofoil also experiences a drag force D in the direction of the free stream (relative velocity). These lift and drag forces can be resolved into tangential (in the plane of rotation) and axial (normal to the plane of rotation) components FT and FA respectively. Fig. 1.6 Notation for determining lift, drag, and axial and tangential forces on An aerofoil[7] Resulting expression for axial and tangential forces FA = LcosÃŽÂ ± + DsinÃŽÂ ± FT = LsinÃŽÂ ± DcosÃŽÂ ± The axial force is absorbed but the turbine while the tangential force causes the turbine to rotate. For a symmetrical airfoil the direction of tangential force is the same for both positive and negative values of ÃŽÂ ±. Therefore, the direction of rotation of the rotor is independent of airflow direction. 2 AIMS AND OBJECTIVES OF THE PROJECT Simulation of air flow through wells turbine impeller by means of numerical method using a CFD (Computational fluid dynamics) called FLUENT and check the flow process of different parameters and the factors affecting the differences. Since wells turbine is a low efficiency turbine to increase the efficiency of Wells turbine is the other aim. Path followed to meet the requirements is first calculation of efficiency theoretically. Simulating a modified design by using different angle of incidence and making biplane i.e. two rows. Comparing the results of different model and selecting the suitable design. 3 LITERATURE REVIEW: 3.1 Types of CFD PROCESS USED: Commercial CFD code: FLUENT, Star-CD, FLOW-3D, CFX/AEA, etc. Research CFD code: Self-developed Public domain software (PHI3D, HYDRO, and WinpipeD, etc.) Other CFD software includes the Grid generation software (e.g. Gridgen, Gambit) and flow visualization software (e.g. Tecplot, FieldView) Commercial CFD code FLUENT is used in this project. 3.2 General working on CFD Table3.1: CFD working layout The Processes shown in the table 3.1 is divided into pre- process and post- process viz. GAMBIET AND FLUENT General sequence of GAMBIT operations Initial setup Solver selection, Mesh size, Defaults, etc. Geometry creation (ACIS, IGES or Mesh import) Create full geometry Decompose into mesh-able sections Meshing Local meshing: Edge and Boundary layers Global meshing: Face and/or Volume Mesh examination Zone assignment Continuum and Boundary attachment Mesh export General sequence of FLUENT operations Selection of appropriate models. Turbulence, combustion, multiphase, etc. Define material properties Fluid Solid Mixture Prescribe operating conditions Prescribe boundary conditions at all boundaru zones Provide and initial solution Set up solver controls Set up convergence monitors 3.3 Grid generation: Grid generation is one of the key elements in Computational Fluid Dynamics (CFC). It has now become a fairly common tool for use in the numerical solution of partial differential equations on arbitrarily shaped regions. The numerical solution of partial differential equations requires some discretization of the field into a collection of points (nodes) or elemental volumes (cells). The differential equations are approximated by a set of algebraic equations on this collection, and this system of algebraic equations is then solved to produce a set of discrete values which approximates the solution of the partial differential system over the field. The practice of discretizing the physical domain into a finite number of elements is called as grid generation. 3.4 Grid topologies Generally, the governing equations may be transformed into finite element, finite difference, or finite volume equations. The cell types supported by FLUENT are followed as: triangular and quadrilateral cells in 2D are accepted, and in 3D, tetrahedral, hexahedral, wedge, and pyramid cells can be used FIG3.2: Different types of grids Structured versus Unstructured Grids The section presents a brief description of grid generation. The grid generation techniques available at present fall into two categories, namely: a) structured grid generation and b) unstructured grid generation. The structured grid generation techniques are based on the transformation of the complex physical domain into a simple computational domain, which is often chosen to be rectangular in shape (quadrilateral and hexahedron). The unstructured grid generations have been used with FEM (finite element method) procedure only, whereas structured grids have general applicability.[7] . 3.5 Types of structured grid In FLUENT, both single-block and multi-block structured meshes are acceptable, as well as hybrid meshes containing quadrilateral and triangular or hexahedral, tetrahedral, pyramid, and wedge cells Multiple Block Sometimes, it is possible to combine several structured computational meshes together to fit the physical domain. Multi- locking has the advantage of the speed of a structured solver, without as many mapping constraints apparent in single block meshes. Single Block In this technique, one computational grid is mapped to fit the whole physical domain. For even moderately complex shapes, it may be practically impossible to define a transformation which will map the outer surface of the computational domain to the required physical shape, while ensuring that the resulting grid has desirable attributes of smoothness.[7] 3.6 Mesh quality The quality of mesh plays a significant role in the accuracy and stability of the numerical simulations. The attributes associated with mesh quality are density of node, cell shape, smoothness and flow-field dependency. In many cases, poor resolution in critical regions can dramatically alter the flow characteristics. 3.7 The Capabilities of FLUENT This section provides a brief introduction to FLUENT and an explanation of its capabilities [10].FLUENT used in this project is a commercial code and a state-of-the-art computer program for modelling single and multiphase flows, heat and mass transfer, chemical reaction phenomena, and etc. in complex geometries. This code includes following components; FLUENT, the flow solver; GAMBIT, the pre-processor for geometry modelling and mesh generation; pre-PD, and etc. FLUENT solver utilizes a finite-volume, pressure-based, multiphase space marching method (SIMPLE algorithm), for solving the governing integral equations for conservation of mass and momentum, and for energy and other scalars such as turbulence and chemical species. It has the following modelling capabilities: à ¢Ã¢â€š ¬Ã‚ ¢ Flows in 2D or 3D geometries using triangular/tetrahedral, quadrilateral/hexahedral, or mixed (hybrid) grids that include prisms (wedges) or pyramids à ¢Ã¢â€š ¬Ã‚ ¢ In compressible or compressible flows à ¢Ã¢â€š ¬Ã‚ ¢ Steady-state or transient analysis à ¢Ã¢â€š ¬Ã‚ ¢ Laminar and turbulent flows à ¢Ã¢â€š ¬Ã‚ ¢ Newtonian or non-Newtonian flow à ¢Ã¢â€š ¬Ã‚ ¢ Convective heat transfer, including natural or forced convection à ¢Ã¢â€š ¬Ã‚ ¢ Coupled conduction/convective heat transfer à ¢Ã¢â€š ¬Ã‚ ¢ Radiation heat transfer à ¢Ã¢â€š ¬Ã‚ ¢ Inertial (stationary) or non-inertial (rotating) reference frame models à ¢Ã¢â€š ¬Ã‚ ¢ Multiple moving reference frames, including sliding mesh interfaces and mixing planes for rotor/stator interaction modelling à ¢Ã¢â€š ¬Ã‚ ¢ Chemical species mixing and reaction, including combustion sub models and surface deposition reaction models à ¢Ã¢â€š ¬Ã‚ ¢ Arbitrary volumetric sources of heat, mass, momentum, turbulence, and chemical species à ¢Ã¢â€š ¬Ã‚ ¢ Flow through porous media à ¢Ã¢â€š ¬Ã‚ ¢ One-dimensional fan/heat-exchanger performance models à ¢Ã¢â€š ¬Ã‚ ¢ Two-phase flows, including cavitations à ¢Ã¢â€š ¬Ã‚ ¢ Free-surface flows with complex surface shapes FLUENT can provides a number of boundary conditions, including: à ¢Ã¢â€š ¬Ã‚ ¢ Velocity or Pressure Driven Inlets/Outlets à ¢Ã¢â€š ¬Ã‚ ¢ Stationary or Moving Walls, with or without Friction à ¢Ã¢â€š ¬Ã‚ ¢ Periodic Boundary Conditions à ¢Ã¢â€š ¬Ã‚ ¢ Symmetry Boundary Conditions à ¢Ã¢â€š ¬Ã‚ ¢ Pressure Far-filed Boundary Conditions à ¢Ã¢â€š ¬Ã‚ ¢ Outflow Boundary Conditions à ¢Ã¢â€š ¬Ã‚ ¢ Inlet/Outlet Vent Boundary Conditions à ¢Ã¢â€š ¬Ã‚ ¢ Intake/Exhaust Fan Boundary Conditions As the Well turbine has a complex geometry for modelling, a large number of modelling capabilities are required of the CFD code for the turbine. FLUENT can incorporates all of these capabilities, and is most suitable for modelling the Wells turbine.[10] 4 ANALYSIS OF TASK 4.1 Theoretical calculation: The dimension used in this project is of prototype obtained from others experimental work, the model is designed and simulated by using the two different models shown in the table below. a [8] b[9] Table 4.1 Dimension of wells turbine The theoretical calculation of efficiency is done using the above two different dimension, the method used to calculate the efficiency is shown below.

Usig a Trendline option in Microsoft Excel an equation of direct relation between angle of attack and efficiency is obtained. The equation shown in the graph is a sixth order equation which is difficult to differentiate to obtained the angle at which the efficiency will be maximum,so a 2nd order equation is obtained from trendline option. Differentiating the equation gives the value of an angle at which the efficiency is max. From this procedure 12 degree is the calculated angle obtained at which the efficiency is max.

Fig 4.6: Impeller of wells turbine Creating a model using gambiet and then meshing the geometry for which meshing size is selected based on the Reynolds number. Since the Reynolds number lies in the transational flow at the angle in which the efficiency is maximum,using turbulence boundary layer formula: à °Ã‚ Ã¢â‚¬ ºÃ¢â‚¬ ¦ =0.00269 The thicknes of boundary layer is 0.003 m. The mesh size comes to be 0.001m to get three elements in one layer to get fine meshing. In case of 3-Dimensional model the mesh elemet used is Tet/Hybrid. Checking the meshing quality the Aspect Ratio lies between 1 to 4. Boundary conditions is given for impeller is moving wall and interfaces is decided so that the fluid can be rotated within this volume. The mesh is exported for post processing in Fluent 4.3 Fluent (Post Processing) Steps used in fluent is as follows: Step 1 Opening the case file Step 2 Defining the grid interfaces Step 3 Grid check Step 4 Defining model as viscous and using K-epsilon (2 equation ) Step 5 Defining boundary condition In boundary condition fluid within the impeller is made to rotate at 40 rads/sec. The impeller is a moving wall rotating relative to cell zone at 0 rads/sec. Inlet velocity is 10 m/sec and the turbulence method selected is intensity and hydraulic cylinder. Step 6 Solution is converged after ilteraion 5 RESULTS AND DISCUSSION: The results shown below contains pressure contours, velocity vectors and pathlines at different cros-section of the models designed using the dimension from table 4.1 (a). Model with blades at 0 degree angle of incidence and inlet flow from top Model with blades at 0 and 2 degree(+) angle of incidence and inlet flow from top Model with blades at 0 and 2 degree(+) angle of incidence and inlet flow from bottom Model with blades at 2 degree(+) angle of incidence and inlet flow from top Model with blades at 2 degree(+) angle of incidence and inlet flow from bottom Biplane models Model with blades at 0 degree angle of incidece and inlet from top Model with blades at 0 degree angle of incidence and inlet flow from bottom Model with blades at 2(+)and 2(-) degree angle of incidence and inlet flow from top Model with blades at 2(+)and 2(-) degree angle of incidence and inlet flow from bottom Model with blades at 0 degree angle of incidence and inlet flow from top Model with blades at 0 and 2 degree(+) angle of incidence and inlet flow from top Model with blades at 0 and 2 degree(+) angle of incidence and inlet flow from bottom Model with blades at 2 degree(+) angle of incidence and inlet flow from top Model with blades at 2 degree(+) angle of incidence and inlet flow from bottom Biplane models Model with blades at 0 degree angle of incidece and inlet from top Model with blades at 0 degree angle of incidence and inlet flow from bottom Model with blades at 2(+)and 2(-) degree angle of incidence and inlet flow from top Model with blades at 2(+)and 2(-) degree angle of incidence and inlet flow from bottom Comparing the above graphical results under a range of 0-400 for comparison except the last two model. The table below shows the value of dynamic pressure (max) in Pascals of above design. From the table it can be seen that the introduction of two rows provides a better result in terms of dynamic pressure. After giving the installatoin angle the maximun dynamic pressure obtained is 1176 pascals by which we can say that the two rows impeller with and an installaition angle is better than the single rows .

John Lennon Essay -- essays research papers fc

John Lennon "You've got to admit it's getting better it's getting better all the time," because of John Lennon, and the way he effected the world. "Imagine" the world without John Lennon. John Lennon had a huge effect on the world. Throughout his life Lennon was many things. He was a musician, lyricist, singer, artist, actor, humorist, political and peace activist, and writer. Because of Lennon the world was changed musically, socially, and politically. Musically he brought rock music into mainstream music. Socially he inspired a generation of teenagers. Politically he started up the movement to "Give Peace a Chance." He became the leader of the sixties, one of the most turbulent eras to date, and the role model to many people young and old around the world. John Lennon did not have any easy childhood. Lennon was born on October 9, 1940, in Liverpool, England (Bil 1). This was during the height of World War II, and his parents named him John Winston Lennon after legendary British Prime Minister, Winston Churchill. Lennon's parents were divorced and his father was working on a ship away from home when he was born. When his father came back, his mother would not let his father see him. So his father tried to kidnap him. His mother could not let this happen again so she sent him to live with his Aunt Mimi and Uncle George. Aunt Mimi ran a strict household, and he did not really relate to her while he was growing up. So Lennon became a very close friend with his mother. Tragically in 1958 his mother was killed in a car accident right in front of him (Norman 1). Aunt Mimi sent him to Quarrybank Grammar School, but he was very bored and preferred writing and drawing. Lennon did not enjoy school life, and became a rebel at a young age. He often skipped class, and when he did go to class he sat and drew. His future looked very grim. When Mimi asked the headmaster of the school to write a letter of recommendation to the Liverpool School of Art, it gave everyone new hope. Lennon didn’t do well here either, while he loved to draw, he found the Liverpool School of Art too ridged and structured. He liked his drawings to be from his heart and full of emotion. He found that the curriculum did not allow him to do this. During his art exam Lennon drew cartoons, so he failed (Norman 1... ...e alive today, but "Let it Be." Works Cited Bil.

ICT Meeting Special Needs

The person that I am going to be studying is Mr. C Aziz a man who lost his eyes when he was at the age of 32, due to an accident with a group of hooligans assaulting Mr Aziz on his way home one evening. Now Mohammed is currently 32 years of age and he and his wife live with their two sons. Mohammed Aziz is a musician, who aspires to one day be able to play as well as his idol Stevie Wonder. The topic blindness is often stereotyped to the thought of sight being gone forever, however in some cases of Blindness there is a chance of seeing again, however sadly in Mr Aziz's case, this is not a possibility. Blindness is the inability to see anything. Some people are called blind, even though they can see a vaguely. This is because they cannot see clearly, but can only see fuzzy shapes or colours. In modern countries, few young people are blind. Blindness is mostly caused by diseases of old people, like cataracts and trachoma. Sometimes, though, people are born blind. Some people are colour blind, which means they can see, however cannot tell certain colours apart. When people are blind they use such things as the alphabet in Braille and guard dogs to do every day things. Although again in Mohammed's case sadly he is not colour blind but fully blind. Technology 1 Braille Watch Braille watches have raised dots that allow a blind person to tell the time. Simply flip up the cover and feel the dots on the dial. There are different types of Braille Watches like the voice one that tells you the time when you need it and it is in digital and normally time. In Braille watches you can save appointments and notes and you can save birthdays and you can record voice and in also can tell you the temperature. Advantages o It's is small and the right size to fit a hand and says it in voice the time and date o Help people with appointments and helps them to not forget time and date and if they got anything information o Tell you everything in English, 99 different languages o It is like a person that is standing next to the blind person and helping Disadvantages o Not waterproof o Easily breaks o Something's very disturbing o Gets lost o One of the bad thing about Braille Watches is that it only reminds you once and that's bad because maybe the person is fast a sleep and can't hear it so they will mess the alarm How the technology meets their personal needs The Braille watch is particularly important in the life of Mr Aziz as it fits directly into his daily schedule. Mohammed, a devout Muslim, needs to wake up at 6am on a daily basis so he may do his daily prayers. The Braille watch is good for this as it allows him for one to be able to actually know the time, to know the right time in which he must pray, it also helps him as some Braille watches also have alarm clocks on them, this however may not be an option for Mr Aziz as, he has a very low budget, as a musician living off benefits from the government and disability benefits he does not have much money to be spending on luxury items, nevertheless Mohammed believes that religion is a very vital aspect of his life, and must uphold all traditions so an alarm is a must (Mohammed believes that if he devotes his life to his religion then one day his eyes may be healed by a miracle. The Braille watch also helps Mr Aziz as it allows him to keep track of when to take his eye medication. Even though Mr Aziz's eyes are now permanently obsolete, he must still use his droplets to prevent any infections in his eyes that may cause him discomfort, and with the help of the Braille watch he is able to know the time at all times and keep track with his medical schedule. Finally although Mr Aziz is sadly blind, he is still a very joyful individual person overall and likes to enjoy himself, with the help of the Braille watch, Mr Aziz he is able to watch all his favourite TV programmes on time without missing a single moment of the show. I believe that the Braille watch is an excellent technology in helping the blind or visually impaired to keep good track of the time. With the compact designs that house the Braille watch, and the voice helper, with over 99 languages built in, as well as a tonne of other gadgets, including I believe that the Braille watch is the ultimate timepiece of the 21st century when thinking of how to help the visually impaired with timekeeping. However with the Braille watch, the problem may arise that if the watch is broken, or needs repairing in any manner then getting the watch repaired is a very tricky matter, firstly it may be very costly as there are not many shops that repair Braille watches, and secondly as I just said there are not many stores that sell Braille watches so finding a shop which would repair the watch would be a strenuous task in itself. How the technology meets their social needs The Braille watch is pretty hand when it comes to Mr Aziz's social needs. As the Aziz family is quite lazy, Mr Aziz relies on his watch to wake up in the morning and to wake up his fellow family members for both work and school. As was said before Mr Aziz is over a very cheery man, he does not allow his sight to bring him down in life, this is why he has many friends in his local area, the element of kindness and happiness is very strong in the heart of Mr Aziz, so attracts the friendship of many of his peers. The Braille watch allows him to keep up to track with his friends on a daily basis. Another branch of Mohammed's daily routine consists of him going to one of his neighbours house daily to discuss topics such as football and their married lives, however Mohammed must wait until 10:15 every day to attend his friends home as he must wait for the children to be sent to school and the missus to go to work, this is where the Braille watch comes in, it allows Mohammed to keep track of the right time him to make his daily visit to his acquaintances' home. Everyday Mohammed rings his home town of Afghanistan to check on his brothers, sisters and parents and see how their lives are going. The time zones however are very different in these two regions of the world, so Mohammed has to use his watch to know the right time, so he does not call at an inconvenient time when his parents are sleeping. His wife is not able to help him with this as well as she works a very tight shift to try support her family (however she does not do it very well, working as a shop assistant on minimum wage makes it very difficult) so she does not have the time to call Mohammed and tell him the time in Kabul, this is why the Braille watch is very vital in his social life. Moreover, everyday at lunchtime Mr Aziz goes to his local school, Wembley Manor Primary School and recites compositions on his piano for children during their lunch break, as part of a good citizenship programme he set up a year ago. The Braille watch is very important as he only plays the piano during the children's lunch time which only lasts 1 hour, so Mr Aziz cannot be late, obviously there will be no penalty for coming late to this job, as it is all voluntary work, however the children enjoy his piano playing very much and would be terribly disappointed if he did not make a session, this is why Mr Aziz needs to hold on to his Braille watch and know the right time to get to the school. As was said before, if the watch does in fact get ruined or needs repairing, then on top of trying to find a store that restores Braille watches, he would need to get one of his friends or wife to escort him to the store, as he cannot see himself, this may bother his friends if they are busy and do not have time to take him. How the technology meets their needs in employment Mohammed Aziz is a composer and composes melodies for himself and for retail; she can make a living, although at the time being he has not been selling much. Mohammed needs to be able to have certain times of the day where he dedicates it to his music, so as not neglect his music, this is where the Braille watch fits in, Mr Aziz sets it on reminder everyday at 9pm so it rings and reminds him that he needs to finish his composing, this may be done without the use of his watch, by his wife reminding him if he forgets, however his wife is not at home at all times, she sometimes goes over to her neighbours house for their book club, and Mr Aziz forgets also at times so using the Braille watch is the most efficient way to remind him of the tasks he needs to do. I think that even though the Braille watch does an adequate job in helping Mohammed keep up with his work schedule by reminding him of the time he needs write his compositions, there may be a better technology such as a handheld PC with Braille keys that could assist him around the day. This however is very pricey and probably not in Mr Aziz's price range, so must be reconsidered, also if it is bought, the issue of thieves must also be thought, a Handheld PC specially made for blind people is very pricey and if a thief is to take advantage of Mr Aziz's disability and rob him of his Handheld PC, then the financial implications should be thought about, does Mr Aziz have enough money to replace something so expensive, will it impact his family financially leaving them in debt? These are just some questions that would be thought of when buying something so expensive for Mr Aziz. If the watch breaks down before Mohammed is due to go to work (his voluntary work) then he may not be aware of the time and miss his normal music session at Wembley Manor, upsetting the children because they did not see their favourite musician playing during their lunch hour. Technology 2 Braille Notetaker The Iris kb line offers portable and compact personal data assistants equipped with Braille keyboards and refreshable Braille displays of 20 or 40 cells. This line is part of a range of new generation Braille devices by Euro Braille. These devices incorporate a broad range of applications and are available with either a 128 MB internal storage capacity 256 MB capacity. The series of four keys on both sides of the keyboard, used for navigation, have been placed as closely as possible to the keyboard to minimise hand movements. This helps achieve a more ergonomic design aimed at reducing your risk of repetitive motion injuries. Spreadsheet applications allow you to work with data and formulas in cells that are identified by line and column, Calculator applications allow you to make basic calculations, File Explorer application facilitate handling files and folders in a tree structure, Calendar application pages to organise your appointments and tasks, Contacts pages to easily store and retrieve all your contact information when you need it and more.

The note taker is also very light which allows Mohammed to keep it in his pocket without weighing him down, or sticking out of his pockets bringing any unnecessary attention for muggers or anyone with the intention to steal the note taker. Furthermore the note taker is actually very expensive, with a price ranging over à ¯Ã‚ ¿Ã‚ ½3000 it is no way in Mohammed's budget, however if he does receive one some way, perhaps from the government free of charge, to help his disability, then the small size will matter as it does not attract unwanted attention. The Note taker also meets Mr Aziz's personal needs as it has a 128mb or 258mb internal hard drive, which will allow him to store his music on. As Mohammed is a musician he has a strong passion for music, so being able to listen to his music frequently will bring great joy to him. The note taker will also allow Mr Aziz to keep a track of all special occasions through the use of the built in calendar that comes with most note taker, now Mr Aziz will never forget any special occasions or important dates. How the technology meets their social needs The Braille note taker is quite good in terms of Mr Aziz's personal needs. The note taker allows Mr Aziz to keep in constant contact with his friends who travel regularly, due to their jobs. The note taker allows him to do this by letting him send and receive emails. The note taker also allows Mohammed to exchange music with his friends via USB, this is a great advantage as he does not have to go out and buy the songs to listen to them, he can just get them off his friends if they have the songs on their PCs. As I said before, Mohammed's friends travel a lot due to demanding jobs, sometimes they are allowed to take a guest with them to the different locations of the world that they must go, so to feel Mohammed feel better about his eyes, they take him with them as their guests. However sometimes during their travels they sometimes get lost as they are in a foreign country and do not know their way around, this is where the note taker comes in, Mohammed can go on a website such as Google maps to then find the route to their destination. If unfortunately Mr Aziz's note taker was to be accidently damaged, lost or stolen, this could bring problems for not only himself but for his friends also. As Mr Aziz does not make a lot of money in his profession, he may need rely on his friends financially to fund for another note taker, or for the repair to his current note taker, this may be awkward for his friends as they must help him as they are his friends, but at the same time need the money so are then in a moral dilemma, to help their blind friend, or to keep the money and use it for themselves. This could also resolve in disputes amongst the friends if some help out Mohammed and others don't, some of the friends get be angered as to why they did not help him out. How the technology meets their needs in employment The Braille note taker helps Mr Aziz in his profession, as it allows him to message his record manager to tell him when his new compositions are ready; it also allows him to receive messages from his record manager to know times of important meetings, and times for his studio recordings. The note take also helps him in his work as it allows him to write his compositions, which needs to sell and make his living, without the compositions there would be no way for his music to succeed. Again the problem arises that if he loses the note taker, or it gets stolen, then he would have a very big problem on his hands, for one it would cost a lot of money to either replace the note taker (money which he does not have) or repair, but the other great problem would be that all of his appointment times and record dates would be gone, not only that but also all of Mr Aziz's compositions are saved on his note taker, so if he loses it then his songs would be lost as well, making him working as a musician obsolete as he does not have the tools for his success, his songs. Technology 3 Talking Typer for Windows Computer keyboarding and typing training software that speaks and displays lessons on screen. Includes drills, practice, and typing games. Adjustable to the student's level of skill and sight impairment. Recommended ages: 6 and older. Built from the ground up with blind and visually impaired students in mind, Talking Typing Teacher features digitized human speech, which is used everywhere in the program. This means that whether you're navigating menus, changing options, managing dozens of student accounts, or visiting the Help Desk, you'll enjoy listening to Eager Eddie read the screen. What makes TTT so special, however, is that each and every typing lesson or practice session is read aloud with clear, concise pre-recorded dialog. Put quite simply, you won't need to worry about trying to understand synthetic speech when you're learning to type with TTT. The only thing Text-To-Speech is really used for is to read your name and play back text you type into Workbook, a fully-functional talking word processor that ships with Talking Typing Teacher. Advantages o Built-in human speech (in the form MarvelTalk) that narrates the entire program o Complete interaction with both sound and full-colour animations o Detailed lesson curriculum designed with three levels of instruction o Full support for multiple student use. This means that you can have more than one student set up with the program, and TTT will pull up each student's record when he or she logs in. o Three levels of instruction that not only change the number of keys that are taught, but also how the instructions are worded and presented o Lessons that teach and reinforce typing, with careful emphasis on posture and correct typing habits o Lessons consisting of spoken and displayed instructions, practice drills, and final reminders o CD-ROM Drive o Intel Pentium @400 MHz Equivalent or Higher o Keyboard o Sound Card o 96MB RAM Disadvantages o Very old How the technology meets their personal needs This meets Mohammed's needs very well, as he is blind and needs to write using the Braille keyboard, it wastes a lot of time, however with the help of the talking typer Mohammed is able to quickly and efficiently type things on applications such as Microsoft word, all he has to do is say the sentence and the talking typer will automatically type the sentence out for him. It also helps Mr Aziz because as he is blind, he cannot navigate the mouse around the PC to find certain applications he is looking for, however with the help of the talking typer he can quickly and easily open applications by saying a couple of simple words, such as â€Å"open Microsoft Word† and then the application will be opened. The technology is very good for Mohammed Aziz as now he may be able to use the PC without the help of others, as he does not now need to rely on others for help, it now makes Mr Aziz feel happy about himself and not so useless and at a disadvantage due to his disability (even though he is, no one wishes to feel like they are worthless). The talking typer however does have a few faults to it, firstly it is a needs the hardware to operate, a microphone. This is a disadvantage as microphones can be easily broken due to their small flimsy fatigues; additionally it is much easier to be broken by a blind man as he cannot not see what he is doing. Furthermore the there are a very vast variety of applications and documents which exist in PCs, it is very hard for Mr Aziz to remember the names of all of these applications so that he can open them through voice commands, this is the extent which the technology meets his needs. How the technology meets their social needs The talking typer is fulfils his social needs to a great extent. As Mr Aziz is quite a popular guy thanks to his cheery attitude, he has plenty of friends, and likes to regularly socialise with them. He does this by meeting up with them, speaking to them on the phone, and emailing them or talking to them through an instant messaging service such as MSN Messenger. The talking typer allows him to make quick responses through the email service by just quickly saying everything that he wishes to be in his email, whereas before he had to wait for his wife to come home and type it all out for him (as he does not like using the Braille keyboard, it inflicts a slight pain in his fingers keeping them in the same positions typing constantly) Mr Aziz also uses the internet to buy clothes and his shopping through websites such as www.Asda.co.uk and www.Littlewoods.co.uk. With the help of the talking typer he can quickly order the goods through voice commands. How the technology meets their needs in employment The Talking typer does not help Mr Aziz is his profession very much. This is because he does not need to use the PC in his profession, and even if he does he may use his note taker instead, it is much more compact and can be used at any time or place, when he is inspired for a song he can quickly note down the ideas he has for his song rather than going home, wasting time and losing his inspiration. The talking typer is however good in some ways, it allows Mr Aziz to quickly memorise his lyrics, by inputting his lyrics through the talking typer he can then make the computer reply the lyrics and listen and memorise the words. Overall I do not think that there could be a better technology than the talking typer, perhaps a technology that connects directly to your mind and allows you to see computer images in your mind, would really benefit blind people, as it gives them the opportunity to actually see and use the computer efficiently, however this sort of technology has not yet been invented, but could be the hope for the future for the visually impaired.
