Evaluating Communication Strategies Essay

You are working as a human service worker at a local United Way agency that serves several multicultural clients. In addition to the multicultural aspect, the agency also serves children, women, the elderly, and the homeless. Your manager has asked you to decide the best communication approach for each of these clients. Answer the following questions: What would you need to learn or know about each of your clients in order to communicate effectively with them? What strategies or techniques do you believe would be the best approach to take when communicating with each of these clients? How might you need to adapt your communication approach from one individual to the next? Working in the Human Services field can provide you with many different types of job opportunities each requiring their own specific needs to clients, many different types of clients that is. To communicate in an effective way with clients getting to know about them is a great start. Listen is top priority to understanding and getting to know your clients. Active listening describes the effort on the part of the listener. Active listening involves giving verbal feedback on the content of what was said, along with recognition of the feelings underneath. Qualities of a good listener include: being non-aggressive, being self-confident, having the ability to let thin gs go along with the ability to work things out. Listening opens the door to meaning. When you hear the person, understand the situation and the feelings, then you are in a position to take constructive action or to reply to her or him in a way that makes sense. Helpful listening helps people look at their ideas, plans, hopes, concerns, fears, etc. It helps them gather information, solve their problems themselves and try out other alternatives. * Communication may seem easy, but to many people’s surprise it is something that has to be learned and practiced. Some of us have developed poor listening skills; we may be judgmental or don’t allow others to speak. Some of us may use close-ended questions exclusively, and do not allow others to explore and contribute to  the discussion. A few strategies and or techniques that allow us to see a better approach to communicating can be using open-end questions such as Where would you like to begin? What options have you explored? Which concern would you like to talk about first? Can you tell me more about that? Open-ended questions encourage the exploration of thoughts and feelings by leaving individuals free to answer in any way they choose. On the flip side, closed sided questions s force a specific answer. They often present themselves as roadblocks to good communication. Sometimes you need specific information (i.e. what city do you live in?). Be sure the information you request is relevant to the person’s situation. Use fact-finding, limited-response questions sparingly. A closed question allows for a limited response. Understanding that each client is different from each other, focusing on each client while actively listen, not judging and knowing that the client is there for help is a way to adapt your communication between clients and or patients.

Rabbit, Run

Rabbit, Run Rabbit, Run was published in 1960 by American author John Updike. He wrote three more Rabbit novels, one at the end of the '60s, '70s, and '80s. He says these novels became â€Å"a running report on the state of my hero and his nation. † He won the Pulitzer Prize for the â€Å"final† two books. series continued after Rabbit’s death in Updike’s 2001 novella, Rabbit Remembered. In 2006, The Rabbit series was voted number four on The New York Times list of â€Å"the best work of American fiction of the past 25 years. Rabbit, Run was also selected by Time magazine as one of the top 100 books from 1923-2005. And the novel is also listed by the American Library Association as one of the 100 most frequently banned books in the 20th century. Banned? set in 1959, Rabbit, Run touches on some delicate issues, like prostitution, male and female orgasms, alcoholism, adultery, blow jobs, homosexuality (though only briefly and ambiguously), birth control, ab ortion, and even accidental. Its 26-year old protagonist Harry â€Å"Rabbit† Angstrom even leers at 14-year old girls (though only to make his girlfriend jealous).Rabbit, Run also has lots of conversations between people arguing about different Christian philosophies, a main character with a bit of a Jesus Complex, a couple of atheists, and even a Freudian. Rabbit, Run was also what some consider a â€Å"biting critique† of America in 1959 The American Dream meant being married with children, and having the latest in modern appliances and beauty products. Many of these issues are barely visible in the novel, but a working knowledge of America 1959 might help us understand the characters a little better. Themes Rabbit, Run Theme of FearFear pervades Rabbit, Run, though the novel does provide moments of relief. The main character, Harry â€Å"Rabbit† Angstrom thinks he’s caught in a contracting and expanding â€Å"trap,† or â€Å"web,† or â₠¬Å"net. † He runs to counteract the fear this trap produces, though he’s usually running, literally, in circles. Fear drives Rabbit to run, and to be still – to leave, but to always return. He’s afraid the trap he’s stuck in is the trap of mediocrity; he’s sure something better awaits him. So he runs. Yet, he has obligations to others, and he fears that abandoning them makes him a bad man.So he goes back and forth. And back and forth, until his final run at the end of the novel. Rabbit, Run Theme of Religion Rabbit, Run is suffused with religious questioning. Much of the religious debate in the novel relates to variations of Christian philosophy, but Freudianism (treated something like a religion), atheism, and a brief appearance, or rather, disappearance of the Dalai Lama provide interesting contrasts. Some of these perspectives are pretty risky for the McCarthy-ist and Red Scare era 1959 that provides the backdrop for Rabbit, Run.The drowni ng death of a newborn baby challenges the religious beliefs of many of the characters, and even provokes her father to dream of founding a new religion, based on â€Å"the truth† about life and death. The end of the novel does not tell us if he fulfills the dream’s prophecy. Rabbit, Run Theme of Identity Rabbit, Run explores the ways in which individual needs and desires, responsibility, family, religion, pop culture, and The American Dream circa 1959 impact the identities of its characters.The tension between American pioneerism and American conformity results in an identity crisis for the novel’s main character, Harry â€Å"Rabbit† Angstrom as he runs back and forth between them trying to escape an all pervasive â€Å"trap. † The results can be both stunningly beautiful and utterly shattering. The open ending leaves it to our imagination (unless we read the sequel, Rabbit, Redux) as to what extent the characters’ identities are, or arenâ⠂¬â„¢t, changed by the drowning death of Rabbit’s newborn daughter. Rabbit, Run Theme of Drugs and AlcoholJohn Updike’s Rabbit, Run, published in 1960, is obsessed with alcohol and cigarettes. But unless you count delivery room anesthetics, drugs are only mentioned on the first page – some basketball playing kids are smoking weed – almost like Updike, writing about 1959, is predicting the ’60s and ’70s to come. Alcohol is mostly presented as a destructive force; whenever the characters get near it, disaster on small or large-scale results. Cigarettes too are presented as mostly destructive, contributing subtly and not so subtly to the smokers’ problems. Though at one moment a cigarette is seen as â€Å"a wafer of repentance. So go steal the keys to the liquor cabinet and – oh, you know Shmoop’s just kidding! Rabbit, Run Theme of Guilt and Blame Rabbit, Run is a guilt and blame-fest. This starts at the beginning of the n ovel when the main character, Harry â€Å"Rabbit† Angstrom, runs away from his pregnant wife and his son. But when newborn Rebecca June Angstrom drowns in a bathtub, things get messy. Rabbit’s wife Janice admits she drowned the baby while drunk. Yet Rabbit is a prime suspect, especially to himself. He is a suspect precisely because he was not there when the baby died.All of the other characters in the novel are suspects too – everybody simultaneously feels guilty and wants to blame others. Even the novel’s setting, America of 1959, is a suspect. Rabbit, Run Theme of Transience Rabbit, Run’s main character Harry â€Å"Rabbit† Angstrom is in a perpetual state of transience. He’s always on the move, usually on foot, though he’s occasionally found in a motor vehicle. He only stops to sleep and mate, and occasionally, to grab a bite to eat. Why does he run so hard? Because he thinks something better than what he has is waiting for h im.At the same time he’s afraid of deserting the people he cares about. He runs back and forth trying to find some kind of balance. Rabbit, Run challenges us to wonder if we are settling for mediocrity when sitting still, or risking everything when we make a move. Genre: Family drama: Families. Drama. Horror or Gothic Fiction: Mysterious traps. Priests. Hallucinations. Fear. Dead babies. Literary Fiction: Fancy prose style. Neurotic. Quest: Somebody looking for something. Realism: True to life. Mystery: Mysterious crimes. Innocent victims. Trying to find the truth. Tone: Degrading when talking about JaniceSympathetic Many characters in Rabbit, Run say, do, and think harsh things. But a tone of sympathy, and even love pervades. And man are these folks judgmental. Like when Rabbit calls Janice stupid, or when he calls himself a criminal. The tough talking narrator, though it seems to call for a complete overhaul of social norms, also seems to suggest that we are all just people , and people make mistakes. When we are able to identify with flawed or disliked characters, we can sometimes gain real introspection, as well as a deeper understanding of those around us. Rabbit, Run SummaryTwenty-six-year-old Harry â€Å"Rabbit† Angstrom runs home one evening to find his wife, Janice, who is seven months pregnant, at home – without their son Nelson and without the family car – drinking, again. They argue, and he leaves to fetch the car and the boy, but along the way decides to permanently hightail it out of Mt. Judge, Pennsylvania and drive until he gets to the beach. He drives in circles and ends up back in Mt. Judge the next day. Instead of going home, he goes to see his high school basketball coach, Marty Tothero, who introduces him to Ruth Leonard, a sexually experienced woman about his age who has dabbled in prostitution.Rabbit and Ruth hit it off famously, and Rabbit decides to drop his car off for Janice, grab a few clothes, and shack u p with Ruth in the city of Brewer, of which Mt. Judge is a suburb. While leaving his old pad he is pursued by Jack Eccles, the minister of Janice’s family’s church. Eccles and Rabbit develop a friendship of sorts, which mostly consists of Eccles trying to convince Rabbit to return to Janice while battling (and coaching) him on the golf course – and of Rabbit getting into some heavy flirting with Eccles’ wife, Lucy. Two months pass. Rabbit and Ruth are for the most part happy.Rabbit has left his work as a MagiPeel Peeler salesman and found fulfillment in the widowed Mrs. Smith’s fabulous fifty-acre garden. Yet, signs of trouble are emerging in the Rabbit and Ruth household. Ruth is about a month pregnant, but hasn’t told Rabbit yet. Ruth and Rabbit go out for drinks one night and things get ugly. Rabbit feels that Ruth took the side of her old lover, Ronnie Harrison, when Ronnie was clearly giving Rabbit a hard time. Rabbit interrogates Ruth as to her sexual history with Ronnie, and then, upon finding out that she gave Ronnie a blowjob, requires Ruth to give him one to ake up for her traitorous behavior. She does, and a little later that night Reverend Eccles calls to tell Rabbit that Janice is in labor. He leaves Ruth to go to Janice and soon becomes the proud father of one Rebecca June Angstrom. While Janice is recovering, Rabbit moves back into their old apartment with his son Nelson, and cleans the place up while spending quality time with the boy. Janice gets out of the hospital, and things are OK. Janice isn’t drinking. Rabbit is working for her dad, selling used cars. But after nine days both Janice’s body and mind are feeling postpartum strain.That Sunday, Rabbit goes to Eccles’s church for the first time (leaving Janice and the kids at home to rest). He gets into some deep flirting with Lucy Eccles and comes home wanting to have sex NOW with Janice. The baby won’t stop crying though, for like hours, and the whole time Rabbit is trying to get Janice to drink (to put her in the mood), chain smoking, and clinging to her in case she suddenly feels like having sex with him. Finally, the baby stops crying, Nelson goes to bed, and Rabbit gets Janice to take a drink.They get into bed and Rabbit tries to have sex with her. Still sore from giving birth, from her episiotomy, and from Rabbit living with â€Å"a whore,† Janice rebuffs him. He gets mad and leaves. Meanwhile, Janice really does start drinking, and drinks all day Monday in fact. Frantic and depressed, she slaps Nelson. Her mother calls and upsets her, and then she finds that Rebecca June has somehow gotten baby poop all over herself and her crib. Drunk and full of anger, confusion, and fear, Janice tries to give Rebecca a bath and accidentally drowns her.Rabbit calls Eccles that night and finds out what happened. He’d spent the night in a motel and the day trying to catch a glimpse of Ruth, but w ith no luck. He busses back to Mt. Judge full of shame and remorse. Why is he so ashamed? Because he really thinks, most of the time, that he killed his daughter by not being in the apartment at the time of her death. He feels like he took out a hit on the kid when he walked out on Janice. He really convinces himself, and is disappointed that the law doesn’t consider him a suspect.This guilt makes him more determined than ever to work things out with Janice. To stay with her forever to atone for his sins†¦but†¦ At the end of Rebecca June’s burial service he loudly accuses Janice of murdering their daughter and loudly proclaims his innocence. Humiliated, he runs. He runs to Brewer, finds Ruth, and guesses she is pregnant. She is really nasty to him and threatens to abort the baby if he doesn’t divorce Janice so he can marry her. He agrees, but when he steps out to pick up food from the deli, as you’ve probably predicted, he runs†¦And the boo k ends. 950’s: experienced marked economic growth – with an increase in manufacturing and home construction amongst a post-World War II economic boom. 1960’s : In the United States, â€Å"the Sixties†, as they are known in popular culture, is a term used by historians, journalists, and other objective academics and pejoratively to describe the era as one of irresponsible excess and flamboyance. The decade was also labeled the Swinging Sixties because of the fall or relaxation of some social taboos especially relating to sexism and racism that occurred during this time.The 1960s have become synonymous with the new, radical, and subversive events and trends of the period, which continued to develop in the 1970s, 1980s, 1990s and beyond.

Things Fall Apart Chinua Achebe

China Achebe, has achieved textual Integrity through a set of core Ideas which are developed through the characters and events In the novel. The novel shows the drastic effect of white missionaries who colonies an African clan of Bib people; bringing with them a new religion as well as laws, punishments and very deferent customs. Events described In the narrative highlight that a community and or an Individual must at some point adapt to change and a new environment or face being marginal's by the society.Awoken also works ere hard to show his strength, as an individuals fear of failure and social humiliation may influence their behavior in society as well as isolate them. Particular characters In the novel manifest how religion and spirituality create a sense of safety and stability In society as well as something to fear. Achebe has portrayed these concepts in the community of the Bib people through the coming of the missionaries and the downfall of the protagonist, Awoken. A commu nity and or individual must at some point adapt to change and a new environment or face being marginal's by the society.When the white missionaries come to the village of Ambulant they eventually build a hospital and a school, and welcome everyone to ]Olin In their beliefs bringing the Isolated and the deserted together and giving them meaning in their lives. This is in harsh contrast to Awoken who wants to resist and bring back the familiar and known ways of the clan. â€Å"Awoken said that ‘until the abominable gang was chased out of the village with whips there would be no peace†. This harsh statement conveys his unbending personality and his narrow view of the way the situation should be dealt with: as he its contrary to his clansmen.This inability to adapt and accept the changes in his community lead to Ginkgo's ultimate downfall. â€Å"That man was one of the greatest men In Mafia. You drove him to kill himself;† The white Commissioner was blamed for the de ath of Awoken; blamed for his seclude. At some point it becomes a necessity to change adapt or even simply accept new arrivals and change or face not being able to live. An individuals fear of failure and social humiliation may influence their behavior in society as well as isolate them. Awoken has worked his whole life to be different to is father and show the strength he has in him.It plays a huge part in his personality and affects how he treats people and how he reacts to things; always trying to be the opposite of his father who in his eyes was a failure. â€Å"Fortunately among these people a man was judged according to his worth and not according to the worth of his father. † Achebe's dramatic irony reveals Awoken has nothing to fear as his people will only Judge him on his individual worth and not his fathers actions. Awoken never showed weakness or any emotion that was not anger. He had no patience for ND a temper, which his family lived in fear of. But his whole lif e was dominated by fear, the fear of failure and of weakness†¦ It (his fear) was not external but lay deep within himself†¦ It was the fear of himself, lest he should be found to resemble his father†. This consuming fear of himself dominated his life, made him who he was and influenced his behavior so much so it lead to regrettable mistakes.

It was powerful in war and in magic.The fear of magic is strong and protects Muffle from war, and well as defends it.

Spirituality can give an individual power and a revered status. The Priestess of Cabala Juxtaposes other women in this book, differentiating herself from the crowd with her ability to communicate with the spiritual realm and the Goddess Cabala.Spirituality and religious beliefs constitute an unquestionable power and a fear no one can contradict. One must be able to accommodate change and conform to society to a certain extent to allow improvement in oneself and even ones culture which is ever changing, ever improving otherwise one can face being left behind, being marginal's or unable to endure the lasting effects. Awoken could not change or accept the changes in is community, he concentrated on not failing himself and avoiding social humiliation and keeping a stable and respected status in community which can influence ones behavior in society, or lead to isolation.Spirituality creates a sure sense of balance and security and a fear that establishes order in a society which Achebe provokes through the novel and states the idea in many forms as to be accessible by all .

Travel Motivation Essay Example | Topics and Well Written Essays - 2500 words

Travel Motivation - Essay Example With the changes in the structure of the society, more purchasing power in the hands of the people, rightly associated with more stress, tourism worldwide has grown beyond proportions. It is now declared as an industry like any other industry. Motivation has always been an important consideration in the field of tourism (Pearce & Lee, 2005). Motivation is seen as the driving force behind all actions. Travel motivation is challenging because of the different human needs. The purpose of travel is no more just business or pleasure. The tourist visitation patterns and the result of a destination choice pattern are influenced by the tourists’ motives and backgrounds. Tourist motivation can be defined "as the global integrating network of biological and cultural forces which gives value and direction to travel choices, behavior and experience" (Pearce, Morrison & Rutledge, 1998 cited by Espinoza). A desire for novelty and difference, the curiosity to remove the myths about exotic pl aces gives tourism a boost. Tourism ranges from Jerusalem to Bangkok and shapes politics, creates identities, and manufactures history. Today we hear of spiritual tourism, health tourism, nature tourism, casino tourism, sex tourism, dark or grief tourism, sustainable tourism, eco-tourism, adventure tourism, space tourism and heritage tourism. This paper will discuss how different forms of tourism have come into existence to meet different needs of the tourists especially in the context of New York as a tourist destination. Market segmentation in the tourism industry is based on travel motivation factors. A study conducted on Switzerland as a destination revealed that the number of leisure trips that any person undertook and the duration of the trips have reduced. These have been related to significant time constraints in certain segments of the traveling public. This is an indication that Switzerland’s travel market has entered the maturity stage. It also demonstrates that

Coaching and aligning a team - Term Paper Example This cooperation among team members can be enhanced further by the leadership of the team leader. For the time being, the Chairman must play the role of the team leader and must consider the fact that even when team members are intelligent or hard-working, each member has their own strengths and weaknesses. His experience and wisdom can ably guide the management team to work together. However, initially it can be a daunting task to ensure that each team member has left any previous experiences and biases behind so they can focus solely on the current situation. Katzenbach and Smith (1993), write in an article titled, The discipline of teams, note â€Å"When individuals approach a team situation, especially in a business setting, each has preexisting job assignments as well as strengths and weaknesses reflecting a variety of talents, backgrounds, personalities, and prejudices† (p. 168). This meant being very effective in coaching the management team to focus on their rolees and stay out of politics. The chairman must also learn how to listen to the members of the Board but he must be firm in emphasizing that they should not be involved in the operational aspects. Another advice that the Chairman of the Board can take is that he must employ his excellent interpersonal skills. This would mean being open, frank, or straightforward in his transactions with both management team and board members. It would be helpful to have good demeanor in communicating with the team since they are all professionals; however, as Chairman, he must speak out his mind to arrest the situation. He could start by having a personal briefing to each member ( both mgt, team and board members) so he can address the issues directly and succinctly. By doing so, he is evaluating the opinion of each person which can help him make his own decisions later. In short, he is consulting the people as a coach. Managers do appear to prefer medium by corresponding it to the richness of the

Does data and analysis present a good argument Debating the research Assignment

Does data and analysis present a good argument Debating the research method of an article - Assignment Example The large size of sample is associated with biasness during presentation due to the work load involve, a confirmation that differences are as a result of size bias not mode selected. Sampling mistake arises in the sampling procedure itself as not all parties of the outline population are assessed (Easterby-Smith et al 2003). Normative model is used during web surveys as opposed to paper and pencil procedures. What I could have suggested for the authors of the article is to reduce the sample size. By using accommodating sample size it is easy to manage the sample bias. Normative model presents an opportunity for participants not to pay much attention as compared to face to face or telephone surveys (Easterby-Smith et al 2003). I would suggest combining normative model with instrumental model to improve sample bias and check ramifications of low response rate (Vieira et al 2002). The research relied mostly on qualitative research rather than employ mixed research method. Vieira, W., De La Tour, K., & De La Tour, S. (2002).

Stylistic analysis Coursework Example | Topics and Well Written Essays - 1500 words

Stylistic analysis - Coursework Example In his column for Time Magazine (Krauthammer â€Å"Dignity†), written shortly after the memorial was opened, Krauthammer supported the decision to eschew the desires of many disability advocates and in a prominent sculpture, cover FDR’s wheelchair. Typical of Krauthammer’s writing style, he took the issue and transformed it into a scathing criticism of contemporary politicians’ penchant for self-exposure. This is something Krauthammer does often in his polemic style of writing: he starts out discussing one topic and adeptly switches it to another to effectively make his point, with wit and plenty of logic. A review of his most recent columns, published in The Washington Post and in 200 other newspapers and media outlets, demonstrates this technique. In another of his columns about the FDR memorial, for example, he starts off by talking about the movie â€Å"Pearl Harbor,† which he calls â€Å"an engagingly ramshackle mess of comical improbabilities, 40s clichà ©s and dialogue so corny it must have been (was it?) deliberate† (Krauthammer â€Å"Campaign†). Krauthammer then uses a scene in the movie, which has President Roosevelt uncharacteristically open about his disability, to illustrate how both the movie and the memorial went against Roosevelt’s wishes to conceal his disabilities. It is an effective tool, one made more powerful when the reader remembers that the one using the tool is also a user of a wheelchair, and most likely holds the same opinions about disability as FDR did. While Krauthammer has never gone on the record expressing those opinions, his behavior and dignity would seem to support it. Krauthammer’s disability occurred when he was a first-year medical student at Harvard University, in a diving accident. In spite of this, he graduated with his class in 1975 and went on to a successful medical practice, with a wide range of publications in his field of psychiatry

It is possible to highlight two basic figures in the film that develop a plot and action. These are considered to be women those names are Hae-won and Pong-nam (Cho, 139-140). They have different characters and different faiths, but they both are presupposed to cruelty to some extent. The first one is represented as a cold lady with a severe and even brutal character. She works in a bank, lives in a big city, but is tired from all of this. She is used to behave impertinent and rude with all people around her. The moment that she becomes a witness of a crime and does nothing for the help of unfortunate woman proves the indifference and cruelty of her soul. Even when Hae-won’s old friend asks for the help she refuses despite the fact that she has been willing to provide it. The second woman represents the images of victim and murderer. This woman lives in a rural landscape and suffers from sexploitation and other bullying from people around her. Moreover, that is considered to be her husband, brothers and old women. Her soul is full of pain and infliction. Still, the patience of Pong-nam comes to an end when she loses her daughter and gets a refusal to save her from this hell. Since this moment Pong-nam becomes a murder. The thirst for revenge seizes this woman and she starts to requite for all pain that has been inflicted to her. In addition, it is relevant to admit the contrast between the settings that are represented in the film. The plot of â€Å"Bedevilled† develops in a huge city Seoul and rural place Moodo. Through these images it is possible to parallel civilized society and uncivilized one. City is viewed as a place where people can earn a lot of money and live better, while countryside is represented as a terrible and awful

Taxation Assignment Example | Topics and Well Written Essays - 750 words

Taxation - Assignment Example 129). The anti-abuse rule introduced by HMRC strikes down the tax avoidance schemes, regardless of whether they are technically sound. It is possible to implement the law correctly if the avoidance scheme is abusive. HMRC could view the situation as a violation in case the gain was not disclosed. One of the professional requirements of a member would be to ensure that he does not assist a client to arrange or commit an offence since it is unlawful (Chartered Institute of Taxation, 2011, p. 20). From an ethical viewpoint, the most appropriate thing to do would be to advise Henry to avoid such a consideration since it is not legal. It would be vital to give Henry appropriate advice since he continues to act for him as a client. After the expiry of an initial period of an official enquiry, the Tax Management Act (section 29) provided a mechanism that would assist in the assessment of an individual’s income tax. The mechanism also assists in the assessment of capital gains in the following four years. Such assessments might take place regardless of whether they are in support or whether they are the consequences of an enquiry. The power to make the assessment is triggered when an HMRC officer makes a discovery that complies with the rules specified in Section 29. In Henry’s case, the discovery relates to the development of an insufficiency in an assessment. The self-assessment process provides HMRC with a straightforward system that assists in the mitigation of uncertainty. HMRC has the power to correct the glaring omissions, which is one of the ways through which the revenue can require additional tax liabilities. Conversely, the corrections can impose excessive reliefs under section 29. If the tax agent fails to provide information requested by HMRC, the body will investigate the agency to determine the possibility of dishonest conduct. In the case of a failure to supply information required, HMRC will charge the agent with civil penalties. Subsequently,

707 week 6 - Assignment Example It is however relatively expensive, has limited scope, and may be susceptible to environmental factors. Interviews involves oral presentation of prompts to which a research participant respond and could be face to face or involve the use of technologies such as phones or computer and internet applications for oral and visual communication over long distances. Unlike in observation, interviews involve the research participants and therefore induce threats of participant bias though it offers more in-depth information. Questionnaires, however, have written prompts and establish a distinction between a researcher and research participants. It is less expensive, convenient, and flexible, and the use of technology, such as in online enhances these advantages (Kothari, 2004). A research aims at developing knowledge, from existing data, for solving a problem or bridging information gap and reliability and validity ensures realization of the aims. Reliability defines consistency in data and ensures that results and implications are consistent with identified problem while validity ensures accuracy in knowledge development for addressing a research problem (Heavey, 2014). It is necessary to code collected data before analysis because coding aligns data with analysis objectives and selected analysis technique (Lester, 2013). Gender is one of the identified variables and 1 will represent male while 2 will represent

Tesco organization structure Essay Example for Free

Tesco organization structure Essay In 1961 Tesco Leicester entered the Guiness Book of Records as the largest store in Europe and in 1968 Tesco opened its first superstore in Crawley, West Sussex. Supermarkets revolutionised the way people shopped and by the 1970s Tesco was building a national store network to cover the whole of the UK, which it continues to expand to this day, while also diversifying into other products. In 1974 Tesco opened its first petrol stations, and would become the UKs largest independent petrol retailer. By 1979 total sales topped  £1bn, and by 1982 sales had doubled to more than  £2bn. In 1987 Tesco successfully completed a hostile takeover of supermarket rival Hillards for  £220m. The battle for top spot In the 1990s Tesco continued to tighten its grip on the UK with more store openings and an agressive marketing campaign in an attempt to overtake Sainsburys as the UKs leading grocer. In 1992, the company launched is slogan every little helps, followed by the Tesco Value range in 1993. This was followed by the launch of the Tesco Clubcard scheme in 1995, helping Tesco to overtake rival Sainsburys as the UKs largest food retailer. 1996 saw the retailer introduce its first 24-hour store while it also expanded overseas opening shops in Poland, the Czech Republic, and Slovakia. In 1997 Tesco appointed Sir Terry Leahy as chief executive. Tesco.com was launched in 2000 and the supermarket continued to expand its range of products, which now includes clothes, electricals and personal finance products. In 2004 Tesco entered the broadband market. Two years ago, in 2006, the retailer announced ambitious plans to open stores in the US under the name Fresh and Easy and funded by existing resources. Tesco now operates in 13 countries. Today it reported that group sales were  £51.8bn in the year to February 23 2008. Pre-tax profit rose to  £2.8bn. In 2008 the retail giant took its conquest of the UK one step further by buying up some rival Somerfield stores on remote islands in Scotland, giving Tesco a presence in every single postcode area in the country. As it stands there is only one postcode in the UK in Harrogate in North Yorkshire which does not have a Tesco. Every little hurts As the supermarket giant has grown, so too has the number of places in the UK dubbed Tesco town. In Inverness more than 50p in every pound spent on food  by the citys 66,000 residents is done so at a Tesco checkout and similar dominance in other towns has sparked controversy. Because of their size, supermarkets have been accused by some of abusing their position by forcing smaller local shops out of business. According to non-profit organisation Ethical Network, local communities could be losing inward investment of up to  £100bn every year because of supermarket centralisation. In 2001 a blackmailer failed in an attempt to extort  £5m from Tesco through a parcel bomb campaign and was jailed for 16 years. In 2008 Phillip McHugh, a former tax inspector, was jailed after threatening to bomb Tesco stores unless they gave him  £1m. Mr McHugh sent 76 letters to the company threatening to blow up shops and poison customers by contaminating food, promising that blood will flow unles s they gave into his demands.

Open Loop Control Method For Conveyor Belt Transmission Engineering Essay

Open Loop Control Method For Conveyor Belt Transmission Engineering Essay Before the advent of modern automation techniques, factory workers often had to travel from project to project. The cumulative effect of all this physical motion was additional stress and inefficient use of the workers time. The development of conveyor belts allowed the project to come to the worker, instead of the worker to the project. Parts could then be transported by other conveyor belts to additional workers, and eventually to the shipping docks for delivery. Many conveyor belts work on the principle of variable speed control. If a particular belt moves too slowly, workers may find themselves waiting for parts. If a conveyor belt moves too quickly, parts may be damaged or workers may become overwhelmed. Much of a factory supervisors time is spent adjusting conveyor belts for maximum efficiency. This is especially important in food production factories, where conveyor belt speed and proper cooking time work hand in hand. Project objectives Modeling of a open-loop control method for conveyor belt transmission Modeling of a close-loop speed control method for conveyor belt transmission Research on the performance comparison for variable mass material input 1.2 Organization of thesis Chapter 2: This chapter thoroughly introduce what conveyor transmission system is and provides a brief history about it. Six categories of typical conveyor transmission system have been introduced. It also explains the sources and types of breakdowns in conveyor belt, as well as the effect of those breakdowns cause in the transmission line. Then, this chapter also discusses about the importance to have speed control for the conveyor belt transmission system. Chapter 3: This chapter mainly focus on different types of motors. It specifically explains about the AC asynchronous motor which is the most widely used in heavy industry. The different speed control methods of AC asynchronous motors have been compared in several aspects. Chapter 4: In this chapter, PID controller is discussed in details for process control, including its definition, history, applications, tuning method and implementation. Unlike other kinds of papers concerning PID control approach, the weakness and bad behaviour were brought about as well so that an objective picture of PID method could be completed. Chapter 5: At the outset, this chapter gives some key modeling process, and then provides the complete models for simulation both of open-loop control and close-loop speed control. With these models, simulation results can be get to make some comparisons. The close-loop results show the performance of different controller parameters on the transmission system with a variable mass material input on several discrete speed value, corresponding to the open-loop curves those seem not to be quite good. Chapter 6: This chapter summarizes discussion and conclusion about the performance of speed control on the transmission system, and then gives out some recommendations and future works that can be done in speed control for conveyor belt transmission system. 2.0 CONVEYOR BELT TRANSMISSION SYSTEM Conveyor belts are generally endless loops which move parts or materials from one location to another. Conveyor belts are often driven by variable speed electric motors or by other moving parts in a complex system. They are commonly found in factories, grocery stores, warehouses and public transportation centers. Further refinement of conveyor belts allowed factory managers to create automated or semi-automated production lines. Individual parts could be moved through automated machinery for routine processing, leaving workers free for quality control tasks or other higher responsibilities. Conveyor belts also proved useful for transporting heavy or hazardous products, reducing worker injuries. The use of conveyor belts is not restricted to factories. Bakeries and pizza shops often use a slow-moving wire conveyor belt to move their products through an oven. Grocery stores use conveyor belts in their check-out lines to bring items to the clerk and bagger. Airports and other public transportation systems use conveyor belts to deliver checked baggage to customers. Warehouses use long conveyor belts to offload products from incoming trucks or to load outgoing ones. Escalators found in department stores could also be considered conveyor belts, as are people movers in larger airports. 2.1 History Primitive conveyor belts were used since the 19th century. In 1892, Thomas Robins began a series of inventions which led to the development of a conveyor belt used for carrying coal, ores and other products.[6] In 1901, Sandvik invented and started the production of steel conveyor belts. In 1905 Richard Sutcliffe invented the first conveyor belts for use in coal mines which revolutionized the mining industry. In 1913, Henry Ford introduced conveyor-belt assembly lines at Ford Motor Companys Highland Park, Michigan factory.[7] In 1972, the French society REI created in New Caledonia the then longest straight-belt conveyor in the world, at a length of 13.8 km. Hyacynthe Marcel Bocchetti was the concept designer. In 1957, the B. F. Goodrich Company patented a conveyor belt that it went on to produce as the Turnover Conveyor Belt System. Incorporating a half-twist, it had the advantage over conventional belts of a longer life because it could expose all of its surface area to wear and te ar.Mà ¶bius strip belts are no longer manufactured because untwisted modern belts can be made more durable by constructing them from several layers of different materials.[8]. In 1970, Intralox, a Louisiana based company, registered the first patent for all plastic, modular belting. In 1963-64, First Indian Small Scale Industrial Unit with Japanese Plant for Rubber Belts for Conveyor / Elevator / Transmission was installed near National Capital Territory of Delhi and its MrBelts Conveyor Belting has been widely used in Steel, Cement, Fertilizer, Thermal Power, Sponge Iron Plants and Coal/Mineral establishments, Port Trusts and similar material handling applications of Industry for the last over 4 decades 2.2 Types of Conveyor System 2.2.1 Wheel Conveyor System A wheel conveyor systems setup consists of skate wheels that are mounted on an axle placed in a row. Depending on the weight of the material being transported, adjustment of both the wheel spacing and the slope for load movement is provided. Being simpler in construction, the system is flexible, scalable and more economical with light-duty applications as compared to a roller conveyor system. 2.2.2 Roller Conveyor System A roller conveyor system has two variants, but both utilize a minimum of three rollers that provide support to the smallest load all the time. Then there are tapered rollers that orient the load around a curved path. The gravity-type system is alternative to the wheel conveyor system that is used for heavy-duty applications. It utilizes a slope for load movement to facilitate the accumulation process. The powered variant utilizes a belt or chain drive for force-sensitive power transmission useful in merging and/or sorting applications. 2.2.3 Chain Conveyor System A chain conveyor system has one or more endless chains that directly carry the load. These chains are placed in a parallel chain manner that can be used in transporting pallets. One variant is the vertical chain conveyor that is used for transferring loads continuously in a vertical direction at high speeds. 2.2.4 Slat Conveyor System A slat conveyor system uses slats placed at discrete positions, and these slats are connected to a chain. Through drives that control orientation and positioning of the load, the transported unit is able to retain its position while being conveyed. The system is used in applications transporting heavy loads that might otherwise damage the belt as in bottling and canning plants. 2.2.5 Vibrating Conveyor System In vibrating conveyor systems, the main component is an elongated load-carrying structure called a trough, bed or tube, based on the application it is used for. A vibrating mechanism produces small amplitude vibrations at a high frequency. This conveys the individual product units and bulk materials. Due to its unique operational manner, it can be used to transport almost all kinds of granular as well as free-flowing materials. 2.2.6 Pneumatic Conveyor System A pneumatic conveyor system uses pipes or ducts known as transportation lines. These ducts carry material mixture along with an air stream. The load gets transported to various locations through pipe lines propelled by the high velocity air streams. 2.3 Components and Breakdowns The belt conveyor system (BCS) consists of (fig. 3): à ¢Ã¢â€š ¬Ã‚ ¢ drive unit (electric motor, coupling multistage gearbox), à ¢Ã¢â€š ¬Ã‚ ¢ pulleys (drive pulley and other), à ¢Ã¢â€š ¬Ã‚ ¢ belts (textile or with steel cords) with their joints, à ¢Ã¢â€š ¬Ã‚ ¢ idlers, à ¢Ã¢â€š ¬Ã‚ ¢ other (belt cleaning systems, control system, etc.) Fig 2.3.1 Belt conveyor transmission system components In this section we will consider the type of faults that may appear in belt conveyor systems with reference to conveyor component s. The drive unit consist of electric motor, damping coupling, two or three stage gear-box and coupling that connect output shaft with pulley (fig. 8). A crucial object in this subsystem is gearbox. According to Matuszewski [5] in a considered lignite open cast mine even 14% of gearboxes may be replaced each year due to unexpected failures. These failures are related to the geared wheel wear or damages (broken tooth) and bearings (mainly over limit backlash due to environmental impact, also typical failures like outer/inner race, rolling element). The mining pulley consist of two bearings, shaft, shell and coating (special material in order to improve belt-pulley contact). The most frequent failures for pulleys are: bearings and shells. For gearboxes number of failures related to geared wheels is 50%. Other critical failure is the damage of input shafts (probably because of overloading) . It may be surprising that bearing faults are not so frequent in gearboxes. The failure analysis of idlers and belts are a bit different issue [7, 8, 11]. Idlers are used for supporting belts with transported materials. In some sense, idlers are similar to pulleys and consist of bearings and shells. One may expect similar types of failures. The support system for belt consists of three idlers. Because of different load for each idler usually side idlers are more subjected to damage. It needs to be added that in CM context of idlers change of condition is not the only one. Worn bearings in idlers will significantly increase external load for drive units so power consumption will increase. Damaged idlers and pulleys may be the reason of damage for belts. Depends on application, belts used in conveyor systems may be divided into two groups: textile belts and steel cords belts. In underground mines usually the textile belts are used. In lignite mines both types may be applied. Expected problems for belts are related to belt (tear, puncture, cut of belt and abrasion of bottom/top covers) and its joints (connected using glue, vulcanized or mechanical joint) [10, 11]. Because of dimension and weight of a belt it needs to be transported in rolls, pieces up to 100-400 m long, depends on a belt type. In order to replace damaged a gearbox or pulley heavy machinery is required. In some cases due to environmental impact (for example rain) it takes a few times longer time. If one consider the impact of damaged idlers it is another story. The idlers are quite small in comparison to pulleys; however, number of idlers is huge. Damaged idlers may cause failure of belt (the cut of a belt) or even may start fire (belt slipping on damaged idler may increase temperature up to 400 °C, 450 °C is the limit for so called difficult-to-burn belt) and as it was mentioned energy consumption is arising dramatically. Any of mentioned failure generates cost of breakdown of machines working in series. It as to be mentioned that a conveyor system, that with random material to be transferred the smoothness and stability of the conveyor belt transmisssion system should be guaranteed to extend all the components lifetime. 2.4 Significance of Research The belt conveyor is one of key components for most of manufacturing systems. Intelligent control of the conveyor leads to the feasibility of a Flexible Manufacturing System (FMS). For most of the assembly lines in manufacturing systems, different processing works applied to products mainly come from workers who is sitting along the conveyor. The products are conveyed by the belt conveyor from one working area to the next. If the average number of products entering one working area is greater than the average number leaving that area, the manufacturing process stagnates. It means that conveying speed is too fast so that more products are conveyed to workers in that working area than the quantity they can handle. Therefore, the conveying speed of belt conveyor needs to be adaptively changed based on the stagnation condition at each working area. On the other hand, if the defective rate of products monitored at outlet of conveyor is too large even though no stagnation has occurred at e ach working area, the conveyor still needs to be adaptively slowed down so that workers have more time to give their processing works with more cares In the long run, maximum number of manufactured products conveyed to the outlet of conveyor is hoped to be achieved if the speed of belt conveyor can be intelligently controlled Since the conveyor is driven by a servo motor, adaptive control algorithm can be designed to control the motor speed based on stagnation conditions at working areas or the defective rate monitored at the conveyor outlet. In addition, belt conveyor is one of main electromechanical systems in heavy industry, especially in the coal transport system, its safe operation plays an important role in the whole coal output systems.Safety is an important aspect in our life, and coal mine still is a high-risk industry in the world. As one of main components in the coal transport system, the safe operation of belt conveyor plays an important role in the whole coal output systems. As the belt conveyors get longer, quicker and bulkier, it is often occurred that the belt rupture, coal vibration, belt slip on the drive pulley, uncontrolled running of the belt conveyor, belt fire and other safety accidents, which bring huge economical losses and threat miner life. In order to insure the miner safety and the normal production, it is significant to carry on safety investigation of the belt conveyor. Higher productivity and reliability are common goals for conveyor systems in mining operations. Key objectives include opt imized mass flows, reduced energy costs and a well-coordinated workflow between the conveying and transport processes.And the key to this problem is to make sure that the transmission system should be operating at a smooth and steady speed. In a word, the steady speed of the conveyor belt transmission system is vitally important.[wiki] 3.0 MOTORS FOR CONVEYOR 3.1 General Motors An electric motor is an electromechanical device that converts electrical energy into mechanical energy.Electric motors are found in applications as diverse as industrial fans, blowers and pumps, machine tools, household appliances, power tools, and disk drives. Electric motors may be classified by the source of electric power, by their internal construction, by their application, or by the type of motion they give. 3.1 Conveyor Motor Types For a conveyor transmission system, the drive unit develops with time. And the motors still using in this era come to the 4 main types: brushed DC motor; brushed DC motor; . The working mechanism of the 4 kinds are discussed as well as their merits and drawbacks. 3.2.1 Brushed DC motors A brushed DC motor has a set of rotating windings wound on an armature mounted on a rotating shaft. The shaft also carries the commutatora long-lasting rotary electrical switch that periodically reverses the flow of current in the rotor windings as the shaft rotates. The magnets field produced by the armature interacts with a stationary magnetic field produced by either permanent magnets or another winding a field coil, as part of the motor frame. The force between the two magnetic fields tends to rotate the motor shaft. Many of the limitations of the classic commutator DC motor are due to the need for brushes to press against the commutator. This creates friction. Sparks are created by the brushes making and breaking circuits through the rotor coils as the brushes cross the insulating gaps between commutator sections. Depending on the commutator design, this may include the brushes shorting together adjacent sections and hence coil ends momentarily while crossing the gaps. Furthermore, the inductance of the rotor coils causes the voltage across each to rise when its circuit is opened, increasing the sparking of the brushes. This sparking limits the maximum speed of the machine, as too-rapid sparking will overheat, erode, or even melt the commutator. The current density per unit area of the brushes, in combination with their resistivity, limits the output of the motor. The making and breaking of electric contact also generates electrical noise; sparking generates RFI. Brushes eventually wear out an d require replacement, and the commutator itself is subject to wear and maintenance (on larger motors) or replacement (on small motors). The commutator assembly on a large motor is a costly element, requiring precision assembly of many parts. On small motors, the commutator is usually permanently integrated into the rotor, so replacing it usually requires replacing the whole rotor. Therefore, DC motor brush design entails a trade-off between output power, speed, and efficiency/wear. 3.2.2 brushed DC motor In this motor, the mechanical rotating switch or commutator/brush gear assembly is replaced by an external electronic switch synchronized to the rotors position. Brushless motors are typically 85-90% efficient or more whereas DC motors with brush are typically 75-80% efficient. Brushless DC motors are commonly used where precise speed control is necessary. They have several advantages over conventional motors:they are very efficient, running much cooler than the other equivalent motors; without a commutator to wear out, the life of a DC brushless motor can be significantly longer compared to a DC motor using brushes and a commutator; brushless motors have no chance of sparking, unlike brushed motors, making them better suited to environments with volatile chemicals and fuels. Also, sparking generates ozone which can accumulate in poorly ventilated buildings risking harm to occupants health. Modern DC brushless motors range in power from a fraction of a watt to many kilowatts. Larger brushless motors up to about 100 kW rating are used in electric vehicles. There are numerous applications using a Brush DC Motor that could instead utilize the Brushless DC Motor. However a few factors might prevent the changeover. The first factor is start-up cost. Although the Brushless DC Motor is lower-maintenance than the Brush DC Motor, initial cost is more expensive, due to its advantageous construction. Second is complexity. A controller is required in order to operate a Brushless DC Motor, and is usually more convoluted than most controllers. A Brushless DC Motor also requires additional system wiring, in order to power the electronic commutation circuitry. 3.2.3 asynchronous AC motor An asynchronous AC motor is an induction motor where power is transferred to the rotor by electromagnetic induction, much like transformer action. . Polyphase induction motors are widely used in industry.The simple design of AC motor is simply a series of three windings in the exterior (stator) section with a simple rotating section (rotor). The changing field caused by the 50 or 60 Hertz AC line voltage causes the rotor to rotate around the axis of the ac motor. The AC motor has the advantage of being the lowest cost motor for applications which require more than about 1/2 hp (325 watts) of power. This is due to the simple design of ac motor. Meanwhile, the simple design of the AC motor results in extremely reliable, low maintenance operation. Unlike the DC motor, there are no brushes to replace for ac motors. If run in the appropriate environment for its enclosure, AC motor can expect to need new bearings after several years of operation. In fact if the application is well designed , an AC motor may not need new bearings for more than a decade. Although the most common and simple industrial motor is the three phase AC induction motor, there are still disadvantages of ac motor. Expensive speed control The electronics required to handle an AC inverter drive are considerably more expensive than those required to handle a DC motor. However, if performance requirements can be met meaning that the required speed range is over 1/3rd of base speed AC inverters and AC motors are usually more cost-effective than DC motors and DC drives for applications larger than about 10 horsepower, because of cost savings in the AC motor. Inability to operate at low speeds Standard AC motors should not be operated at speeds less than about 1/3rd of base speed. This is due to thermal considerations. In fact a DC motor should be considered for these applications. Poor positioning control Positioning control is also expensive and crude. Even a vector drive is very crude when controlling a standard AC motor. Servo motors are more appropriate for these applications. 3.2.4 Synchronous Electric Motor A synchronous electric motor is an AC motor distinguished by a rotor spinning with coils passing magnets at the same rate as the alternating current and resulting magnetic field which drives it. Another way of saying this is that it has zero slip under usual operating conditions. Contrast this with an induction motor, which must slip to produce torque. These motors can be made to operate at leading power factor and thereby improve the pf of an industrial plant from one that is normally lagging to one that is close to unity. And the key feature of a synchronous AC motor is it operates at a constant speed, irrespective of load, from no-load to full load. As well, electromagnetic power varies linearly with the applied voltage. These motors can be constructed with wider air gapes than induction motors making them mechanically better.Whats more, efficiency of operation is usually high, especially in the low speed and unity power factor ranges. However, the disadvantages are also quite obvious. These motors cannot be used for variable speed jobs as there is no possibility of speed adjustment. And it requires external source for supplying dc excitation, cannot be started under load, the starting torque being zero, may fall out of synchronism and stop when over-loaded and so on. In addition, for some applications these motors are not desirable as for driving shafts in small work-shops having no power available for starting and in cases where frequent starting or strong starting torque is required. 3.3 AC Motor for Conveyor Through the comparisons above, transmission system with AC motors are simple to make and can be reliable.And for the low cost, AC motors are overwhelmingly preferred for fixed speed applications in our industrial applications and for commercial and domestic applications where AC line power can be easily attached. In fact over 90% of all motors are AC induction motors. AC induction motors are found in air conditioners, washers, dryers, industrial machinery, fans, blowers, vacuum cleaners, and many, many other applications. Using an AC drive for conveyor control allows the speed to be adjusted to changing needs. A partly loaded conveyor with a higher speed than necessary wastes energy and causes unnecessary wear. In controlling conveyors, AC drives also improve process control by enabling the collection of measurement and supervision information. The soft start of the conveyor with AC drives reduces the stress on gearboxes when the conveyor is started. This paper mainly deals with the AC asynchronous motors, because for industry like coal mine, the asynchronous ones are the mainstream with many successful applications.In the design of the induction motor, operational characteristics can be determined through a series of calculations. Performing these calculations can help the engineer provide a motor that is best suited to a particular application. 3.3.1 SYNCHRONOUS SPEED The speed with which the stator magnetic field rotates, which will determine the speed of the rotor, is called the Synchronous Speed (SS). The SS is a function of the frequency of the power source and the number of poles (pole pairs) in the motor. The relationship to calculate the SS of an induction motor is: Where: SS = Synchronous Speed (RPM) f = frequency (cycles / second) = 60 P = number of poles (pole pairs) 3.3.2 MOTOR SLIP The rotor in an induction motor can not turn at the synchronous speed. In order to induce an EMF in the rotor, the rotor must move slower than the SS. If the rotor were to somehow turn at SS, the EMF could not be induced in the rotor and therefore the rotor would stop. However, if the rotor stopped or even if it slowed significantly, an EMF would once again be induced in the rotor bars and it would begin rotating at a speed less than the SS. The relationship between the rotor speed and the SS is called the Slip. Typically, the Slip is expressed as a percentage of the SS. The equation for the motor Slip is: Where: %S = Percent Slip SS = Synchronous Speed (RPM) RS = Rotor Speed (RPM) 3.3.3 EQUIVALENT CIRCUIT To analyze the operating and performance characteristics of an induction motor, an Equivalent Circuit can be drawn. We will consider a 3-phase, Y connected machine, the Equivalent Circuit for the stator is as shown below: Fig 3.3.1 Equivalent Circuit Where: V1 = Stator Terminal Voltage I1 = Stator Current R1 = Stator Effective Resistance X1 = Stator Leakage Reactance Z1 = Stator Impedance (R1 + jX1) IX = Exciting Current (this is comprised of the core loss component = Ig, and a magnetizing current = Ib) E2 = Counter EMF (generated by the air gap flux) 3.4 Speed Control of AC Asynchronous Motor With respect to the use of AC asynchronous motor, when used with a load that has a torque curve that increases with speed, the motor will operate at the speed where the torque developed by the motor is equal to the load torque. Reducing the load will cause the motor to speed up, and increasing the load will cause the motor to slow down until the load and motor torque are equal. Operated in this manner, the slip losses are dissipated in the secondary resistors and can be very significant. So the speed control of an AC asynchronous motor in the industry world is quite important. From Equ.1 we can get the speed torque characteristic of the machine as Fig. 3.3.2. The curve is rather steep and goes from zero torque at synchronous speed to the stall torque at a value of %S. Normally Slip may be such that stall torque is about three times that of the rated operating torque of the machine, and hence may be about 0.3 or less. This means that in the entire loading range of the machine, the speed change is quite small. The machine speed is quite stiff with respect to load changes. The entire speed variation is only in the range SS to (1à ¢Ã‹â€ Ã¢â‚¬â„¢%S)SS, SS being dependent on supply frequency and number of poles. Fig 3.3.2 Relationship between torque and speed of induction motor The coming discussion shows that the several speed control methods for induction machine, when operating from mains is essentially a constant speed machine. Many industrial drives, typically for conveyor in a belt transmission system, have typically constant speed requirements and hence the induction machine is ideally suited for these. However,the induction machine, especially the squirrel cage type, is quite rugged and has a simple construction. Therefore it is good candidate for variable speed applications if it can be achieved. 3.4.1 Applied voltage control One may note that if the applied voltage is reduced, the voltage across the magnetizing branch also comes down. This in turn means that the magnetizing current and hence flux level are reduced. Reduction in the flux level in the machine impairs torque production. If, however, the machine is running under lightly loaded conditions, then operating under rated flux levels is not required. Under such conditions, reduction in magnetizing current improves the power factor of operation. Some amount of energy saving may also be achieved.Voltage control may be achieved by adding series resistors (a lossy, inefficient proposition),or a series inductor/autotransformer (a bulky solution) ora more modern solution using semiconductor devices. A typical solid state circuit used for this purpose is the AC voltage controller or AC chopper. Another use of voltage control is in the so-called soft-start of the machine. 3.4.2 Rotor resistance control Clearly, the rotator speed is dependent on the rotor resistance. Further, the maximum value is independent of the rotor resistance. The slip at maximum torque is dependent on the rotor resistance. Therefore, we may expect that if the rotor resistance is changed, the maximum torque point shifts to higher slip values, while retaining a constant torque. Note that while the maximum torque and synchronous speed remain constant, the slip at which maximum torque occurs increases with increase in rotor resistance, and so does the starting torque. whether the load is of constant torque type or fan-type, it is evident that the speed control range is more with this method. Further, rotor resistance control could also be used as a means of generating high starting torque.For all its advantages, the scheme has two serious drawbacks. Firstly, in order to vary the rotor resistance, it is necessary to connect external variable resistors (winding resistance itself cannot be changed). This, therefore necessitates a slip-ring machine, since only in that case rotor terminals are available outside. For cage rotor machines, there are no rotor terminals. Secondly, the method is not very efficient since the additional resistance and operation at high slips entails dissipation.The resistors connected to the slip-ring brushes should have good power dissip ation capability. 3.4.3 Cascade control The power drawn from the rotor terminals could be spent more usefully. Apart from using the heat generated in meaning full ways, the slip ring output could be connected to another induction machine. The stator of the second machine would carry slip frequency currents of the first machine which would generate some useful mechanical power. A still better option would be to mechanically couple the shafts of the two machines together. This sort of a connection is called cascade connection and it gives some measure of speed control as shown below. Let the frequency of supply given to the first machine be f1, its number poles b

Alzheimer’s Disease (AD) and Oxidative Stress Relationship

Alzheimer’s Disease (AD) and Oxidative Stress Relationship Alzheimer’s disease (AD) is a neurodegenerative disease which causes a lethal twist in the structural integrity, and a roadblock in the function of brain, this eventually channel the situation to degeneration and shrinkage of brain, and override the control of brain over other parts of the body, and comes to the final closing remark of the disease- death. Studies done on the topic have corroborated that the disease is not reversible, and the only patch of hope is slowing down its progress. But as the disease advances through mid stage and evolves into severe AD, the condition of patient becomes pathetic and care giving becomes more painful. Studies have reported that notable symptoms of AD are seen only after 60 years of age, even though the disease has started before that. Initial symptoms are loss of short term memory- being forgetful about the recent events, and gradually over a period of time patient seems more absent –minded about the environment, things which are chemically etched in the long term memory begins to be erased, and the final stage starts pushing the patient into severe AD which is tremendously pathetic. Studies have proved that loss of function of neurons is the cause of AD. A closer look into the aspect revealed a complex set of events that precede the neuronal degeneration- oxidative stress and imbalance in homeostasis, formation of roadblocks in communication, falling apart of integrity and death of neurons. This enabled to go beyond the findings of superficial studies done and hypothesis developed, and helped to delve much deeper into the inner workings and mechanism of the disease. Hypotheses developed to explain mechanism of AD are: amyloid cascade hypothesis, cholinergic hypothesis and tau hypothesis. Amyloid cascade hypothesis says, APP- Amyloid Precursor Protein, a transmembrane protein involved in main roles of growth, survival and repair of nerve cells- is snipped at wrong places by an enzyme called secretase, leading to the formation of amyloid ÃŽ ² peptides which accumulates to form plaques- amyloid plaques- and bind to synapses blocking the communication channel, event ually causes memory loss. According to cholinergic hypothesis, downward drift in the levels of acetylcholine in brain is the cause for Alzheimer’s disease. Loss of function of cholinergic neurons was found in Alzheimer’s disease patients. Shift in the level of acetylcholine happens due to the lack of two enzymes involved in synthesis and breaking down of acetylcholine. This will lead to loss of function of neurons; brain’s functionality falls apart, and eventually leads to symptoms of Alzheimer’s disease. Tau hypothesis approaches the problem in another perspective, tau protein- a protein associated with microtubules in nerve cells- gets hyperphosphorylated, this enables cross linking among tau protein units, and they back off from being attached to the microtubules. This causes loss of structural integrity of nerve cells, and they collapse and clump to form tangles- neurofibrillary tangles. Studies conducted focusing on the inner workings of these hypoth esis have found that oxidative stress is the reason that enhances plaque and tangle formation, repair mechanisms in cells are unable to solve the situation as the oligomer formation and cross linking are predominantly made by non peptide bonds. In another study, amyloid ÃŽ ² peptides have shown close relation with some causes of mad cow disease. Studies related to genetics of AD have found the link between APOE gene on chromosome 21 and the disease. APOE gene codes for apolipoprotein, and one among its functions is breaking down of APP. APOE has variants, APOEÃŽ µ4 is the one which codes for less active protein whose capacity to break down APP is sluggish. People with this variant gene are more tend to develop AD in later stages of life, and any abnormality related to chromosome 21 also results in AD over a period of time. To know more about the mechanism of disease and its attachment to oxidative stress, further studies have done from different angles, and all the studies have come to a common point, the findings from all the studies stitched together gave a complex and elaborate picture about the mechanism of the disease. Free radical damage leads to oxidation of products in cell. Oxidation leads to new end products of glycation, nitration, lipid peroxidation, and oxidation of nucleic acids. These new end products chemically modify other proteins and compartments inside the cell. Oxidized derivatives impede with the channel of trace elements, and imbalances their homeostasis, and enables proteins like tau to form non peptide cross linking. In response to changes cell up the levels of heme oxygenase-1 (HO-1)- an antioxidant enzyme to mitigate the bad effects from free radical damage- but rapid heaping up of neurotoxic substances goes beyond control leading to severe imbalances, blockage of communicati on channels, and eventually death of neuron. Since mitochondria is the main source of free radicals and oxidative precursors. Certain deletions in mtDNA resulted in change in normal levels and rates of metabolism and production of free radicals. Free radicals formed in mitochondria are short lived and they do not have the ability to cross membrane and reach cytoplasm to cause damage, this led studies in a new direction and found free radicals- OH from cytoplasm- can attack guanidine in RNAs in cytoplasm and this both can cross the membrane and reach into mitochondria, and cause imbalance and production of more stable H2O2 radicals which can come to cytoplasm and react with the channel of trace elements, and starts the primary events for the major causes for AD to come into being. AD starts at neocortex area of brain, and as the neurons die and rupture, the neurotoxic substances- plaques, free radicals, tangles, etc. pervade the nearby nerve cells, and the cycle goes on and graduall y covers the brain and makes it slip out of its normal being.

Software Patents Must be Eliminated :: Argumentative Persuasive Essays

Software Patents Must be Eliminated Software patents threaten to devastate America's computer industry. Patents granted in the past decade are now being used to attack companies such as the Lotus Development Corporation for selling programs that they have independently developed. Soon new companies will often be barred from the software arena--most major programs will require licenses for dozens of patents, and this will make them infeasible. This problem has only one solution: software patents must be eliminated. The Patent System and Computer Programs The framers of the United States Constitution established the patent system so that inventors would have an incentive to share their inventions with the general public. In exchange for divulging an invention, the patent grants the inventor a 17 year monopoly on its use. The patent holder can license others to use the invention, but may also refuse to do so. Independent reinvention of the same technique by others does not give them the right to use it. Patents do not cover specific systems: instead, they cover particular techniques that can be used to build systems, or particular features that systems can offer. Once a technique or feature is patented, it may not be used in a system without the permission of the patent-holder--even if it is implemented in a different way. Since a computer program typically uses many techniques and provides many features, it can infringe many patents at once. Until recently, patents were not used in the software field. Software developers copyrighted individual programs or made them trade secrets. Copyright was traditionally understood to cover the implementation details of a particular program; it did not cover the features of the program, or the general methods used. And trade secrecy, by definition, could not prohibit any development work by someone who did not know the secret. On this basis, software development was extremely profitable, and received considerable investment, without any prohibition on independent software development. But this scheme of things is no more. A change in U.S. government policy in the early 1980's stimulated a flood of applications. Now many have been approved, and the rate is accelerating. Many programmers are unaware of the change and do not appreciate the magnitude of its effects. Today the lawsuits are just beginning. Absurd Patents The Patent Office and the courts have had a difficult time with computer software. The Patent Office refused until recently to hire Computer Science graduates as examiners, and in any case does not offer competitive salaries for the field.

Fear of Polio in the 1950s Essay -- Disease Illness

Fear of Polio in the 1950s Paralytic poliomyelitis, "polio", held a reign of terror over this nation for decades. But unless you were born before 1955, polio may seem to be just another ephemeral disease that has been nonexistent for years. Those born before 1955 remember having a great fear of this horrible disease which crippled thousands of once active, healthy children. This disease had no cure and no identified causes, which made it all the more terrifying. People did everything that they had done in the past to prevent the spread of disease, such as quarantining areas, but these tactics never seemed to work. Polio could not be contained. Many people did not have the money to care for a family member with polio. This was one of the reasons the National Foundation for Infantile Paralysis was organized. The March of Dimes, the fund raiser headed by the National Foundation for Infantile Paralysis, raised thousands and thousands of dollars to help people care for their polio stricken family members and to aid in the cost of research for a vaccine that would put an end to this misery that affected the lives of so many people. Poliomyelitis was the term used by doctors to describe the condition in which the gray (polios) anterior matter of the spinal chord (myelos) was inflamed (-itis). Until a cure was discovered, no one had the slightest idea where "polio" had come from or why it paralyzed so many children. People learned later that, oddly enough, it was the improved sanitary conditions which caused children to be attacked by the virus. Since people were no longer in contact with open sewers and other unsanitary conditions which had exposed them to small amounts of the polio virus as infants, when paralysis is rare, the dis... ...dy of Poliomyelitis, 1954" Medicine (September 1992): 316-320, at p. 317. 23.

Proctor and Gamble: No Links with Satanism Essay

Introduction   Ã‚  Ã‚  Ã‚   It is human nature to be easily lured into tales of the strange and the extraordinary. In fact, any person generally relishes on spinning tales of his/her own probably to attract attention, and for sheer fun, make others believe as if they were true. Nowhere is this more applicable than in the many instances of modern oral traditions. Stories such as the biggest snake reared as a twin of the daughter of the owner of the biggest mall in the city. That this huge snake got lost one day and swallowed one or two customers in the mall. This story has circulated in countless other malls and in plentiful variations.   Ã‚  Ã‚  Ã‚   In the case of one of the world’s biggest manufacturers of household materials, Procter and Gamble experienced one of the unforgettable rumors some malicious people spread in an obvious effort to pull them down. It was allegedly orchestrated by a rival corporation. What happened with Proctor and Gamble that it has suffered losses in business because it was accused of being involved in satanic activity? Just what is the nature of urban legends and its proliferation today inspite of modernism? This paper briefly describes and explains urban legends, the case on the Procter and Gamble and its supposedly satanic connection, and the veracity of the claims to the contrary by the management of the corporation. Discussion   Ã‚  Ã‚  Ã‚   In Microsoft Encarta, urban legends refer to â€Å"contemporary stories that are set in an urban environment and reported as true (sometimes in newspapers) but that contain patterns and motifs that reveal their legendary character† (2006). Why people believe in them and the apparent failure to quash these stories are crucial to our deeper understanding of the nature of this phenomenon.   Ã‚  Ã‚  Ã‚   The myth and controversy that featured well the problem of P&G, gives people in the present time to adjust and â€Å"feel† that urban legends exemplify the fact that at times people would rather believe an unsubstantiated report, even stick to it in the face of obvious lack of proofs. Discussion   Ã‚  Ã‚  Ã‚   What is the case of the Proctor and Gamble company and reasons why the belief that it has satanic alliances? In all likelihood, there was truth to the fact that rival Amway Company made sure that this rumor will reach the public and might probably cause the public to pull out their product support from P&G. Before the controversy, P&G had many little rumors spreading like bush fire. It started with the logo – that of the thirteen stars among the head of a man with horns on his head and the news then communicated that it represented satanic occultism. Later many short stories around the same theme circulated already, i.e. that the CEO of P&G had arranged for an appearance in Donahue show, and supposedly spoke openly of his alliance with the satanic church. Many, after P&G won its lawsuit against Amway, still enjoy the way the story gets around. On a more serious note, what it had escalated to be, authoritarian voices say, was all a part of the fierce marketing approaches that had existed for a time now. After the rumor, approximately 200,000 inquiries were received by the company which all inquired on the satanic church alliance or its friendship with Rev.Sun Myung Moon (known as Moonies) that P&G was accused of. All these were not true because no evidences are available to establish that the P&G CEO or president had this affiliation. Conclusion   Ã‚  Ã‚  Ã‚   Many believe urban legends like what happened with Proctor and Gamble because they think that the strangeness of its logo, are proofs that something â€Å"fishy† is going on. The unstoppable proliferation of the story is deemed to be due to our curiosity of what unfamiliar things are to us. The P&G dilemma remains to be a continued reminder of again, lack of preparations which might probably due to the inconvenient manner of physical preparation.

The Gifted Children

Started in the 1970†³s, America†s Gifted & Talented programs are used to enhance the curriculum of students included in either category in order to challenge and strengthen their unique abilities. These students are usually provided a separate class with specialized lessons in all areas and a teacher with a special degree in gifted education. I feel that it is important that the teacher was a gifted student who would know what the students must face as â€Å"above average† members of their school. The job market for gifted education offers a wide range of opportunity and gifted teachers are needed all over the One of the earliest programs for gifted and talented students was set up in 1974, at The Old Donation Center, in Virginia Beach. Students scoring within the top 3% of students on an assessment test are referred here to be further challenged. These students are considered gifted and have special teachers and classes to promote development of their talents and minds. Programs like this began to pop up around the nation in the 70†³s; however, gifted students were looked down upon by teachers, parents, and peers. Many people considered them to be â€Å"freaks† because they were different. They didn†t understand the implications of the terms â€Å"gifted† and â€Å"talented†. Most people simply expected gifted students to act more mature or to be geniuses, even though gifted students are the same as other children in their needs as human beings. Some gifted students were forced to grow up too fast and some simply ignored the fact that they were smarter than others, thus, they were lost in the shuffle. The irony of it all is that gifted-ness seems to run in families and the children of these repressed gifted students are, themselves, But what exactly is a â€Å"gifted† student? Students (elementary & secondary) are given a repertoire of tests. These tests check IQ, psychomotor ability, specific academic aptitude/talent, creative and productive thinking, leadership ability, and skills in the visual and performing arts. The main requirement, the IQ, is tested by a standardized IQ test (remember, however, that IQ tests are not always perfectly accurate). Ratings are given to each bracket of IQ scores: If a student receives a rating of â€Å"gifted† or higher (130+), he/she is considered to be a gifted student and is introduced into the designated programs. These students are given the opportunity to choose classes that are meant to teach them how to use their minds for critical thinking, reasoning, and artistic pursuits. Students in these classes are also exposed to culture, literature, and other subject areas that are not usually covered in what they term â€Å"normal classes†. The gifted classes are mainly in an open format allowing the student to create the parameters of his/her work and allowing them to be creative in their learning experience. Each class is presided-over by a teacher that has specialized degrees in gifted education. Almost every school in the United States has a need for a gifted class, making job opportunities endless; there are never Gifted teachers must have both a degree in education (secondary or elementary) and a degree in special education (gifted). These teachers are individuals that must have stamina, people skills, and open minds. It is also important (to the students) that the teacher himself/herself was also classified as gifted. It sets a common bond, shows them that the teacher understands the problems they face as so-called â€Å"smart kids†. These students are often ridiculed by heir peers and looked-down upon by their teachers. They are often separated from others their age by a barrier that can only be described as their â€Å"intelligence†. This is why, often, gifted teachers have degrees in administration, counseling, or psychology. All teachers that I interviewed told me that a continually upgraded education is a must (as are additional degrees). In order to keep up with the students one must attend seminars, workshops, special classes, etc. There is no end to the amount of education that could help you to understand gifted students and the role of their teacher†. Also, if a teacher has extra educational qualifications, he/she could be asked to step up to the position of administrator or, more often, counselor. This means pay raises. Though the average salary for teachers is approximately $27,500 per year, it is â€Å"a worthwhile undertaking† according to Jane Mansueto, â€Å"It is incredible to work with gifted students. They are incredible! † She went on to remark that it is fascinating to imagine that they are of the same level of intelligence as the teacher and what they must be feeling inside. She feels that the students are not othered by what their peers think, but actually tend to understand that other†s opinions mean little compared to their own. Mrs. Mansueto taught at Elm Grove Middle School for 5 years. She commented on her role as a gifted teacher to consist of â€Å"one part mentorship, one part hardship, and one part friendship†. When asked what kind of hours she keeps, she laughed and asked if she was supposed to have time off. According to Mrs. Mansueto, unlike a â€Å"normal† teacher, a gifted teacher has no books to go by or preset material to teach, or, for that matter, a preset subject to teach. They are given a blank page and, using input from students, must draw up lessons from every subject area and constantly challenge the inquisitive minds of the gifted. Jane Mansueto attended Trinity College where she majored in both elementary education and gifted education. Her favorite part of being a gifted teacher is being with the students, working hand in hand with them to plan and carry out projects and trips. Though the pay is average, and there is not much room to be promoted if you wish to remain in the classroom, gifted teaching has its personal rewards. Jeff Simpleton, a gifted teacher as well as a former gifted student, states, â€Å"I really think that by being gifted, I am in touch with what they have to go through. They know that I can understand. † Mr. Simpleton†s class consists of 6 high school students, who have many problems due to the intelligence barrier and a kind of isolation that has built up over the years between themselves and their classmates. They seem to feel that they have a reputation that they must live up to. The students try to please everyone†¦ they push themselves with sheer motivation and determination and drive. Mr. Simpleton feels that this is â€Å"what makes them so great†. He feels that anyone with a sense of adventure and a need for something new day after day would find teaching a gifted class to be the perfect job for Gifted teachers are important to the development of their students minds. They are understanding individuals who must work hard to make the curriculum interesting and challenging. With the proper education it is possible to go far as a teacher of the gifted.

Excel Benefits

Excel system MIS 241-001 NC A&T State University A. Define the competitive advantages of an Excel system in general. An Excel system is very useful in the business world allowing many tasks to be overcome more effortlessly.One advantage is calculations enabling issues to be solved with few errors when dealing with placement of numbers and topic in there needed category; along with number placement there is also so many tools and formulas that make finding an answer so much easier, instead of inputting the mathematical calculations for hours on a piece of paper or entering a formula over and over again an excel system allows this process to be done all at once cutting down on redundancy and error. B.Achieving competitive advantages using information systems. When a company is involved with technology that company is thus allowed to grow and change when change is needed. Information systems are achieving this task thought out the business world, helping to improve efficiency and cu tting down redundancy. This achievement over all allows many companies who are at the cutting edge and using technology to its full potential to have personal achievements of there own, a competitive advantage over there competitors.Technology for a company can be very helpful may it be cutting down cost, cutting down redundancy, improving efficiency and workflow or even allow visibility for improves about their competitors. C. Achieving competitive advantages using Excel. Excel has been in use for years within many businesses even still today; one main function of excel is it allows you to organize, manipulate, and change data that has been entered into excel. Over all for this reason excel can provided a competitive advantage if the data being recorded is used correctly in a way that can only improve business function.This data in turn can be produced into valuable information and used for business intelligence to improve on areas that are not preforming to levels need and really just getting down to the core of an issue by using valuable information. D. Providing three examples/areas of using IS/Excel to achieve competitive advantages and explaining how they are done. Excel allows the user to input data then take that recorded data and covert this recorded data into information that can be used to target, track, and understand the current status of a company, over all utilizing and creating business intelligence.However, on the other hand most company’s have no reason not to involve information systems into there company strategy Information systems in one way can allow a company to connect information from different departments, even using a server and multiple computers to cut down company cost and improve networking between different departments. Another asset of using information systems is that it can allow transitions and shipping to become more visible and even understandable making this process only more simple and effective.

Farewell to Arms Is a Novel Without Hope

Ernest Hemingway’s novel ‘A Farewell to Arms’ shows the destitution of war and the hopelessness of life. Throughout times of hardship and despair, the need to believe in a better future is enhanced, and through the horrors of death and injury, Hemingway implies that all is hopeless. Attempts to find meaning through alcohol and sex proved unsuccessful, societies corruption highlights the absurdity of war, and the love Catherine and Henry felt for each other ended in horror. During the war, soldiers turned to the simple pleasures of live in a means finding hope and escaping the misery. The constant drinking and journeys to â€Å"bawdy houses† shows the change in moral standards as the need for meaning in life rises, and the social norms change from modesty to going to the â€Å"whorehouse before it shuts† This lowered standards as a result of the soldiers’ position leads the reader to understand that in war, there is no hope; the constant death and destruction leaves soldiers feeling as though they have no purpose in life. The routine death, to the point that a soldier dying is unimportant, shows the brutality of war on the emotions of men. The positive connotations of â€Å"only seven thousand† soldiers dying highlights the hopelessness of life and the need for an outlet from war. While in normal circumstance one could turn to religion as an answer for the reason behind war and how to alleviate oneself from the terror, Henry and his friends believe â€Å"all thinking men are atheists†, and interrupt the priest when he attempts to tell Henry about the Abbruzi. This disruption of spirituality affirms Hemingway’s belief in the falsehood of religion, and shows how in times of war, society changes itself and consequently, all hope of peace and happiness is lost. Once Henry injures himself and is forced to take leave from the war, it is evident to the reader that the world is corrupt, and it drags everyone with it. While in the hospital immediately following his knee being â€Å"blown to bits†, Rinaldi tries to make Henry realise his sacrifice and accept the rewards that come with it. Despite Henry protesting that he was â€Å"blown up† not during battle, but when he was â€Å"eating cheese†, Rinaldi still believes that Henry could â€Å"get a silver† medal of honour. Even though he knew that he had done nothing courageous or even brave, but was rather injured in the most banal way possible, Henry was still able to receive an award that was meant for those who had made a significant sacrifice in war. This medal was meant for the type of hero Hemingway believed in; one that displayed acts of courage, endurance and stoicism. Hemingway, through Henry, implies that he does not believe in the glorification of war, as he sees it as an incentive for people to continue fighting. This continuation of war only leads to more despair, and ultimately, a life devoid of hope and meaning. vidence Much like in the hospital, at the races, Hemingway once again shows the reader the corruption of the world and the hopelessness that is brought about as a result of it. When Catherine and Henry realise that the race is corrupt and one horse is assured of victory, they decide to â€Å"pool† all their money together and back it. Although once they do not win as much as they hoped, their mindset towards cheating is reversed, and suddenly, Catherine â€Å"does not like this crooked† racing. It can be concluded that people don’t care about the unauthenticity of life, as long as it benefits them. Even Catherine, a woman used to balance Henry’s faults and teach him lessons as a result of her loss, is dragged into the corruption of the world. These acts of corruption highlight the inability of man to act in a truly righteous way, and extinguish all hope of an honest society. While there is an overall feeling of hopelessness, some can be found in the relationship between Henry and Catherine. Their love inspires them to look towards the future, planning and hoping to â€Å"go somewhere† when â€Å"the war is over†. While the â€Å"many long nights in Milan† provided the couple with everlasting memories and hope for the future, the inevitable, and sudden, ending of their relationship further reinforces Hemingway’s view of a hopeless society. The single emotion that can provide some sense of hope and prospect for the future inflicts more pain than any other as a result of the passion and intensity of love the couple felt for each other. When Henry hears the news of Catherine’s haemorrhage and that the death of the woman he loves is imminent, he tries anything possible to end her pain, even turning to religion, a belief he had criticised on many occasion. Even though he believed that he had â€Å"outlived (his) religious feeling†, he pleaded with god to not â€Å"let her die† The repetition of this prayer allows the reader to see the maturity Henry has develop; he has turned from a man who was in a relationship purely because he wanted to â€Å"play the game†, into someone with empathy and real care for a woman. The joy of â€Å"waking and not knowing who it was† with him had left him, and he had developed true affection for Catherine. The strong connection the couple shared made Catherine’s death even more difficult, and reinforces the harsh view of society that Hemingway believed. Death’s winged chariot† took all that had meaning from Henry’s life, and left him a â€Å"cracked† and â€Å"broken† man in a world that was ‘cooked’. ‘A Farewell to Arms’ predominately presents a hopeless and cynical view of the war and life itself, but hope doe s appear as a result of the love between Henry and Catherine. Hope is seen as futile through the soldiers’ actions, the corruption of the world, and the inevitable heartache as a result of Catherine’s death and from this it is evident that the only bit of justice left in the world is love, assuming that it too is not dragged down by war.
