Citizens of the State of Wisconsin, and neighboring states such as Illinois, Indiana and Iowa subscribes to the Milwaukee Journal Sentinel. It does not matter how big the crises are related and they are, they derive from the same underlying problem and most just want attention.

The Decline of the West

These changes could happen from one day to another. How do you tell your family that their economic situation, all of a sudden, has changed because of your new status as unemployed? Especially when family the family is accustomed to the idea of living the sweet life. The Decline of the West† from 201 0 is about a man who experiences the difficult problems of the economic decline. In the short story â€Å"The Decline of the West†, the narrator Mike lives with his family in the outskirts of London. He just got fired and is now on his way home to pass the news of his recent dismissal.Mike used to work 12 hours a day, but despite the fact that Mike now is unemployed, he looks forward to spent time with his family. He has a rough time tying to tell the truth, and so he ends up arguing with his wife and sons instead. The main character of the short story is Mike. He is a 45-year;old man, father of two, and has until now been working in corporate finance. Mike is a hardworking man, who has provided his family with a lovely house in safe surroundings, plenty of material benefits, and an AU pair, who can take care of the house when he is not there.Mike barely sees his family, and admits lankly that the AU pair sees more to his family than he does himself. â€Å"The AU pair saw more of his house and family than he did -â€Å"1 . The sweet welcoming Mike imagined was far from reality. When Mike arrives home, his wife, Imagine, does not even take the time to say hallo to her husband, but simply just passes him by with a gin and tonic mentioning going up stairs to take a shower. â€Å"Imagine passed him in the hall carrying a gin and tonic, saying she was going upstairs to have a bath†2 This indicates that the marriage might not be as warm and loving as one may think.Mike's marriage does not seem to go well. Imagine is not acknowledging Mike, nor is she interested in him. â€Å"Is it attention you're after? † 3 Mike sees himself as a man that gi ves all he can ever Offer to his family, but they are never satisfied. â€Å"l paid for this with my time, intelligence, and the education the state provided me with†4. Mike's view on him self stands in sharp contrast to the adverse image we get of him from the dialogues. The contrast especially becomes clear in the argument between Mike and his older son, Tom. â€Å"Are you joking? You've done nothing for me† . As the argument is developing it proves out that the children, and the mother or that matter, is very unrealistic when it comes to economy and money. No matter how much they get, it is never enough. Mike has always given his children exactly what they wanted, despite the fact that their joy never lasted long. â€Å"The kids had stopped using it before he'd hardly begun paying for it†6. The narrator in the short story is a first person narrator with a limited point of view to the father. By this we get an insight in the fathers thoughts and speculations. He believed he was good at giving things up†7. We see everything from his point of view, so we have therefore have a colored view n the story. The story is written with the use of Pats. We, as a reader, feel sympathy for Mike. Imagine and the children seem greedy and ungrateful. They are products of the capitalistic consumer society. They are all against Mike and he himself takes position as the victim. He appears to be alone with the knowledge of his famish future situation; however, he does not have the courage to face the consequences.Instead he tries to avoid them. Mike does become wiser on his family unrealistic luxurious lifestyle throughout the story. That happens when he notices Queen Elizabeth Sis's crooked smile on a tote. â€Å"How had he never noticed what a sardonic little Mona Lisa smile the blinded-up monarch wore, mocking even, as if she pitied the vanity and greed the note inspired†8. In the world at large, money is what we worship. We are willingly sac rificing the bond with our family to pursue wealth. Mike has never needed anything in his life.As his father said â€Å"Mike you've been stalked by good fortune your whole life† 9. Now that he is unemployed, he suddenly seems to have lost control of his emotions and life. For a moment he even considers to leave this world and all the financial troubles behind. â€Å"How easy t was to fall, and how tempting it was -? suddenly would be best – to die! † 1 0 First of all â€Å"The Decline of the West' refers to the Collapse of Wall Street in 2008, which had a huge impact on the life of millions of people in the West.The western countries are currently in a critic financial situation. Our society, build upon capitalism and materialism demolished when the nation began to spend more than they could afford. This theme is evident throughout the story. Mike reflects on the lifestyle he, and many others had led in the past couple of years. He considers whether the financi al crisis is a penalty for this. [†¦ ]Nonetheless, like many people, Mike had also worried whether the present catastrophe was punishment for years of extravagance and self- indulgence;[†¦ â€Å"11 The title could also be interpreted as a reference to a moral decline of the modern family. The values of love, and closeness are being replaced by the desire to posses and own everything you could ever dream Of. The love for material has taken over the love for our fellow men. We forget about all that really matters and we are only focusing on buying the latest gadgets and promoting our economical status. The grotesque overcorrection and insatiable love for material goods might have caused severe damage to our traditional social values.Mike and his family is an example of this propensity, so the title might as well refer to the social regression in our culture. The financial crisis has resulted in lots of critical problems, but maybe a financial crisis was exactly what we need ed? This could be a break from our unrealistic expenditure. Money can buy you many things, but the happiness from it is limited. Money can buy you lots and lots of material goods, still eventually you will no longer feel the same excitement bout your purchase.Just like the kids in the short story, you will sooner or later cast-off your bought stuff and set your goals up for a new investment. Money can offer things to make people happy, but it does not mean that money can buy you true happiness. Poor people on the street huddling together to stay warm, that is care, which brings out true happiness. Their situation would improve with a little money, however, in the short story where a wealthy family that cannot live together, where is their happiness? Where is the love? Money cannot buy happiness, nor love.

Indian Removal Act Essay

The Indian Removal Act of 1830 was a heated topic in Congress. Defend the passage or rejection of the Act with reference to the moral, political, constitutional and practical concerns of a congressman. The Indian Removal Act of 1830 was at the time, thought to be justified and acceptable. There were two groups, the people who wanted the Indian’s gone, and the people who believed they should be allowed to stay. I believe forcing the Indians out of their territory was immoral, had no effect on the state of Georgia, and it was an abuse of power. When the Indians were being removed from their territory, they were lead out at gunpoint by our military. It’s immoral because there were 17,000 Indians and 4,000 died due to dehydration, starvation, and disease. The Cherokee had rights given to them. â€Å"They were granted their separate existence, as a political community, undisturbed possession and full enjoyment of their lands, within certain boundaries, which are duly defined and fully described and the protection of the United States against all in interference with, or encroachments upon, their rights, by any people, State, or nation,† argues a Maine Senator. The Indian Removal Act disregards every set of promises we have given to them. â€Å"What is the population of Georgia, where there is no room for these few Indians? It is less than seven to the square mile. We, Sir, in Massachusetts, have seventy-four to the square mile, and space for a great many more,† states a Congressman. The occupation of Indians in Georgia had little effect on the society or development of it. Georgia wanted to â€Å"consolidate their society† but they weren’t going to strengthen their community by kicking people out. President Andrew Jackson and President James Monroe, both were for the Indian Removal Act. President Jackson asks, â€Å"What good man would prefer a country covered with forests and ranged by a few thousand savages to our extensive republic?† The Constitution of 1789 gave Congress the power to regulate commerce with foreign nations, and among the several States, and with the Indian tribes. Yes, this is part of the Constitution, but the abuse of power comes in here. We force them out of their territory that we occupied, with guns to their heads, no food, and the separation of their families. I have always surmised that the Indian Removal Act was inhumane, unfair, and ill advised, but I never really knew why I thought that. After reading about it, looking at both sides, it’s clearer. The Indian’s were forced out for a reason that had no effect on the states, and it was abusing the power that the United States had been working for.

Relationships between Children and Parents. Write Me Sometimes and Essay

Relationships between Children and Parents. Write Me Sometimes and Hamlet - Essay Example They bond over a shared love of food and indulge themselves with all types of food when they meet up. They enjoy debating over restaurant choices and evaluating the food they eat, even when the protagonists’ sister begins to join them for their lunch dates, â€Å"The images I have in my head of these Saturdays are blurry, happy pictures† (Ng-Chan, Year). However, the relationship between father and daughter slowly changes for the worse as the daughter ages. Throughout her college life and subsequent years, she develops as her own individual identity and thus makes choices and forms opinions of her own which do not necessarily resonate with her father. Their weekly meetings almost stop completely, and when they do meet, it is evident that they have grown apart. What makes this even worse is a lack of effort on the part of the father. Though the protagonist writes regularly to her father in an aim to keep in touch and to keep him him informed of her life, the father merely rings very occasionally and never writes back, despite the fact that he promises to do so every time they speak. When they eventually arrange to meet in person again, the father is insistent that they meet for lunch, even though the daughter has made it clear she would prefer something else. The fact that the daughter is now vegetarian and her eating habits have changed drastically seems an issue her father cannot adapt to. He constantly questions her eating habits, encourages her to eat more and insists on buying her groceries constantly despite her protests, and their conversation is stilted, â€Å"The rest of the lunch was spent in polite enquiry† (Ng-Chang, Year). The father appears to be attempting to revert back to their childhood relationship through food and refuses to acknowledge that his daughter has changed. Paragraph 2 (Hamlet) In the Shakespearean play â€Å"Hamlet†, the reader is witness to tragic story in which the protagonists parents and their actions and weaknesses, ultimately lead to his demise. To begin with, after his father King Hamlet dies, the character of the younger Hamlet is immediately disturbed by the actions of his mother. Not long after his father’s death, Queen Gertrude engages in a relationship with and marries Claud ius, Hamlets uncle. This causes Hamlet to be distrustful and avoidant of women, as he believes that his mothers disrespect toward his father’s death and overt sexuality is characteristic of all women. It is as a direct result of this that he does not declare his love for Ophelia until she dies, â€Å"By what it fed on / and yet, within a month / let me not think on’t / Frailty, thy name is woman! / A little month; or ere those shoes were old / with which she followed my poor father’s body...† (Shakespeare, trans. 1992, 1. 2. 145-148). At the beginning of the play, the ghost of Hamlets father visits him and demands that he avenge his death as he asserts that it was Claudius who killed him. This immediately puts a huge pressure and sense of foreboding on Hamlet as his father has made it Hamlets mission to murder his uncle. It is in this preoccupation with deciphering Claudius’s guilt in the death of his father, that ultimately leads to Hamlets demise . Were it not for this idea of attaining revenge, Hamlet would not have engaged in the activities which led to his death. As Hamlets stepfather, Claudius plays a very central role in the death of Hamlet. Suspicious and afraid for his life, he arranges Hamlets death, as he did Hamlets father, and it was these actions which eventually led to the death of almost all of the characters in the play. Were it not for t

Central American Immigrants Essay Example | Topics and Well Written Essays - 1500 words

Central American Immigrants - Essay Example For Central American immigrants who have experienced years of political and social strife, immigrating to the US promises opportunity and liberties that they have cease to believe as possible in their respective countries. The issues faced by Central American immigrants is a particular concern since most of immigrants who have become isolated in the US. The situation face by the immigrants are not unique to them or to immigrants. The challenges they face are also shared with other populations that suffer social exclusion or marginalization that may be unique to regional origins . In the critically acclaimed film Toritlla Soup, the plight of many many of these immigrants, particularly those from Central America trying to escape political persecution, face the seemingly impossible choice of having no choice to leave one's country and having nowhere to go. The sense of disenfranchisement prevails in whatever choice they make. At the same time, they also have to struggle with their personal and social identity as they and their family transition to their adoptive communities whose cultural, social and political barriers often lie beyond their competencies to surpass. Ellis and Wright (2005) study of geography and immigration also shows that there are differences in units of assimilation differs based on geography of immigration. They concluded that there is indication that there is sensitivity to political issues. Menjivar (2000) points out that there is a need to develop more intimate perspective of the issue from immigrants points of view. In her study regrading the immigration trends and issues among El Salvadorans, she points out that immigration into the US, whether legal or not, provides limited opportunity for social representation or empowerment. Often, with the focus of "managing" immigrants, policies become insensitive and unresponsive to the issues that are driving immigration trends, in particular those that are illegal. She points out that most policies view immigrants individually without recognizing the informal and formal social networks. The result is that individual immigrants feel that they are isolated from mainstream America n society and rely more on these social groups which can make communicating with the population restrictive, if not combative with the government's various social programs (Johnson, 2006). Menjivar's (2002) subsequent work, this time focusing on Guatemalans, highlight that the challenged that immigrants are often carried over to their offspring whose identity is often split between being American and that of their parent's native country. Anderson (2003) points out that this can create stress particularly for juveniles and also is considered to reason behind delinquency and victimization. Though these populations may have little link or awareness of their cultural or social history they are subject to the social preconceptions that may incite their feeling of marginalization of social exclusion. This has further been attributed to adult victimization and criminal behavior and lead to diminished effectiveness of social institutions and services for these populations as a whole. Survey of the population who have become victims of abuse indicate a significant history of marginalization, cultural or social exclusion (Menjivar & Salcido, 2002). The experience not only incr eases their vulnerability to crime or victimization but also their propensity to commit the acts to others.

Introduction of the role of CSR in oil industry , focusing on British Term Paper

Introduction of the role of CSR in oil industry , focusing on British petroleum - Term Paper Example Oil firms generate a lot of controversy through environmental damage, and therefore, CSR is one of the key approaches to managing negative perceptions of oil firms and the oil industry. British petroleum firms have accepted that the public views them with suspicion and scepticism, so the best way to change this is to use CSR. British petroleum firms like Royal Dutch Shell and British Petroleum PLC have managed to significantly enhance their brand image by sponsoring community programs and actively participating in community benefit activities. According to Frynas (2009:34), the two companies spend a significant share of their profits on improving lives in communities across the world. They have especially been active in academics, providing annual scholarships to bright and needy students who are often hired by the companies later. These are just some of the CSR activities a select few of British petroleum firms engage in. So far, results show that efforts are effective, helping to cultivate trust and good perception of the

All about Jupiter Essay Example | Topics and Well Written Essays - 1250 words

All about Jupiter - Essay Example The most accepted theory is that ice and other solid material combined to form its core. The core increased in size as it attracted other material from other sections of the Solar System resulting in an increased gravitational pull. â€Å"Eventually the core’s gravitational pull became strong enough to capture hydrogen and helium, which were abundant in the solar nebula.† (â€Å"Jupiter†, p. 200) That is why Jupiter consists primarily of hydrogen and helium. Jupiter rotates very quickly for a planet of its size, with a period of ten hours; it revolves around the sun once every eleven years. Like the other planets Jupiter orbits around the sun in an elliptical orbit. (â€Å"Jupiter†) It is approximately 480 million miles from the sun. (Simon) Jupiter is often seen high in the sky, and some its surface features such as its satellites can be seen with a telescope. â€Å"From our planet Jupiter looks like a bright star in the night sky.† (Simon, Introdu ction) It is one of the most luminous objects in the sky next to the Sun, the moon and Venus. Jupiter is considered one of the â€Å"gas planets† because its atmosphere is composed primarily of gas. It is two and a half times the mass of all the other planets in the Solar System combined. Jupiter is one of the Jovian (outer) planets; the other Jovian planets are Saturn Uranus and Neptune. There is no solid surface on Jupiter. Jupiter is composed primarily of hydrogen and helium. It is similar in composition to the Sun. In 2008, scientists were able to define the surface of Jupiter. â€Å"The surface of the planet is defined as the point where the pressure of the atmosphere is 1 bar, which is equal to the atmospheric pressure at Earth’s surface.† (Coffey, â€Å"Surface† n.pag) The pressure and temperature increase deep in its atmosphere, resulting in hydrogen being compressed into a liquid. Partially beneath its surface, the hydrogen hardens and becomes ca pable of conducting electricity. In this metallic layer, electrical currents resulting from the rapid rotation of Jupiter produces its immense magnetic field. In the middle of the planet its enormous pressure may support a solid core of rock that is approximately the size of Earth. Jupiter's upper atmosphere consists largely of hydrogen and a lesser percentage of helium. The interior of the planet is approximately 71% hydrogen, 24% helium and contains minimal amounts of other elements. The atmosphere also includes hints of methane, water vapor, ammonia, and silicon-based compounds. There are also traces of carbon, ethane, hydrogen sulfide, neon, oxygen, phosphate, and sulfur. The outermost layer of the atmosphere contains crystals of frozen ammonia. (â€Å"Jupiter† Wikipedia) The temperature on the surface is about -235 degrees F (-150 C). The temperature on Jupiter increases to about 70 degrees Fahrenheit deeper within its atmosphere. The winds continue to blow at approximat ely 450mph. (Holladay). The atmosphere in Jupiter increases in thickness until it reaches the ocean. The magnetic field in Jupiter is tremendous. Jupiter has the strongest magnetic field of all the planets. Millions of charged particles are confined to Jupiter’s magnetosphere: â€Å"the area in which magnetic field lines encircle the planet from pole to pole.† (â€Å"Jovian Giant†, para.3) Its rings and moons are entrenched in a radiation belt

Technology and Interpersonal Relationships Essay

Technology and Interpersonal Relationships - Essay Example The fast-paced life of people today keeps human relationships on a standstill most of the time. The many things that occupy our time – family, school, building a career at work, etc., have made rushing from one place to another and always lacking time for everything common features in most people’s lifestyles. However, the human need to be connected to others is always present, and so people have turned to technology, specifically the internet, or mobile phones to fulfil this need. Family and friends have become more accessible and available in just a click of a button. The internet also offers a myriad of opportunities for meeting more people, relaxing with online games, sharing pictures and videos and an outlet to express innermost thoughts and feelings to share with others. The question of how technology affects interpersonal relationships is becoming a popular issue nowadays. The generation gap between the older people and the younger generation is broadening. Older people are accustomed to candid conversations with eye contact and are usually adept at reading body language and nonverbal gestures. The young people of today are very much into technological communication via texting, internet chatting, tweeting, etc. and are engaged with their mobile phones, Ipods, Ipads and other gadgets. When brought together, the older people may complain that the younger ones are lacking manners because they do not know how to give due attention to their companions. It is as if they live in their own worlds, with their gadgets as their gateway to reach their friends. Michael Bugeja’s book on the Interpersonal Divide meticulously describes how the technological age has affected humankind, most especially its humaneness in interacting with others. What prevail right now in terms of technology are computers, the internet, mobile phones, television, radio and other media paraphernalia. These things physically separate people from each other but provide a way for them to connect using technology. In Chapter 3, Bugeja explains how the proliferation of computer-mediated communication affects our views, expectations and interpersonal relationships. In computer-mediated communication, so many of our personhood becomes filtered that the communication lacks social cues. It then prevents the establishment of strong interpersonal collaboration and trust especially in cyber environments where invisibility is an option. Thus, when people chat online or send text messages, a lot of miscommunication may take place when the received messages are interpreted differently from how the sender meant it. This is because the text do not show people’s tone of voice, facial expression or non-verbal gestures which contribute to the clarity of the message sent. Media and technology saturate the lives of people with so many tasks they can do simultaneously and that makes them feel productive at a faster rate. When they log-out from the virtual world a nd re-join the real world, they may find it difficult to be accustomed to it for some time. The real world has three dimensions- up, down and breadth. It also offers intricate human sensations experienced in person. Bugeja also explains that interpersonal skills become the result of physical formats in the real world such as touch, eye contact, smell,

Annotated Soap Note - Assignment Example Social history: She denies taking alcohol or drugs but admits to smoking at least two cigarettes daily. She lives a very active life where she does a lot of walking activities. Her diet consists of high calories, fat, fruits, and vegetables. From the information gathered, the patient is likely suffering from bladder infection. Flank pain is associated with renal and upper urinary tract illnesses. In addition, the pain is a sign of underlying illness which in this case is bladder infection (Lippincott & Wilkins, 2008). The illness is diagnosed through a clean-catch mid-stream urine stream specimen to perform culture and determine the presence of bacteria. Concentration that is more than 100,000 organisms per ml of urine rules out the diagnoses (Murray & Pizzorno, 2012). The culture is repeated after seven to fourteen days after therapy to check if it has cleared (Schapiro, 2014). The treatment will include Norfloxacin (Noroxin) 400mg BID for three days (Tripathi, 2013). In addition, the patient is prescribed 100mg calcium C four times daily. It aids in making the urine more acidic that makes it unfavorable for bacterial growth. The best management of bladder infections is preventing the bacterial growth. To attain this, the patient is educated on how to limit the development of bacteria. It includes urinating completely and frequently. In addition, she should avoid keeping urine in the bladder for a long time. Moreover, she is advised on hygiene tips especially how to clean herself after bowel movement. She should perform it from front to back. Furthermore, she should avoid underwear that is from synthetic fabrics that has the tendency of confining moisture. She will be trained on the significance of taking sufficient fluid that is mostly six to ei ght glasses daily, as it eliminates toxins from the bladder (Schapiro, 2014). The patient is also

Rootkits Research Paper Example | Topics and Well Written Essays - 2000 words

Rootkits - Research Paper Example ghted. General Overview of Rootkits and How They Work In definition, rootkits refer to programs that are intentionally made to hinder with system functionality and documentation hence doing away with the information or data which is stored in the computer for different uses. At most of times they are a collection of programs that facilitate spying on people computers (Rimon 1). The major difference existing between rootkits and the worm and virus is that a worm, the likes of the Stuxnet remains or continues attacking the computer system. This means that the worm does not necessary require to attach itself to an obtainable program in the system for its multiplication to occur accordingly (Rimon 1). Viruses, Trojans and worms have since been infecting computers of many user and even different servers that are essential in running electronic businesses. In that sense, fighting viruses and worms has become an issues which needs to be solved through the adoption of the appropriate measure if at all the running, operation of computer system and networking management has to be continued been enjoyed globally. On the other hand discovering/detecting of rootkits is even harder. According to Bidgoli Rootkits can therefore act in some instance as computer viruses or worms (21). Computer viruses and worms affect systems through deleting major documents or files or even putting a stop to website right of entry. The manner in which computer virus and worms attack the system clearly defines how they work (Rimon 1). The current state of computer virus basically is concerned with the Stuxnet worm. This is because the worm appears much different from other worms and virus following the manner in which it works and spreads in the computer system. In definition, the Stuxnet refers to a worm or malware that breaks into the categories of system that manages equipment (Douglas & Sturken 9). This results to permitting an attacker to take for granted control of critical equipments thus interfering with them the way in which it should not be. Generally, the worm originally distributes arbitrarily in the computer system although it involves extremely dedicated malware which multiplies while at the same time interfering with the functionality and performance of the system. The worm spreads into computer systems through various ways, although the most common means of spreading is through e-mail services. Virus and worms work in almost similar ways when it comes to interfering with the computer system (Rimon 1). Viruses characteristically need unsuspecting system users to unintentionally split them. Rimon believes that a number of viruses that are complicated like the Stuxnet worms duplicate and transform themselves mechanically to different computers by calculating different programs like e-mail sharing application (1). This clearly explains the idea that, networking technology is the reason behind major development of threats like worms and viruses which completely interfere with performance and functionality of systems. Other viruses like the Trojans

Young Goodman Brown Essay Example for Free

Young Goodman Brown Essay â€Å"Young Goodman Brown† is a short story written by Nathaniel Hawthorne about a young man who has to endure the experience of temptations of evil and dance with the devil. Goodman Brown is a young adult who has influences all around him swaying him towards evil that he felt were reliable role models. Hawthorne uses literary devices to display many different meanings in this story. In the story, the most common devices are imagery and symbolism. The imagery used is to help the reader understand the symbolism he is portraying. He uses these devices to develop a theme to the story and provide different aspects of good and evil. Many people now a days fall under the temptation of sin, even Christians. Having faith with God is commonly seen as a good relationship to have and gives you a positive outlook on life, but after losing that faith, your world darkens and not everything seems as bright as it did. Hawthorne’s use of symbolism and imagery helps to develop the theme of Christians losing faith through temptation and peer pressure as Goodman Brown does. Hawthorne uses symbolism throughout the whole story to imply influences of evil around Goodman Brown. The young man decides to take a journey one night because he feels compelled to. His wife Faith begged him not to go, but to stay there with her and hold off the journey until the morning. Hawthorne uses his wife’s name as Faith not by accident; she symbolizes his Faith in God and the innocence left in Goodman Brown. Faith has on her person pink ribbons; these ribbons represent the innocence in Faith because the color pink is known as innocence. Brown does not agree to his wife’s wishes and departs on his journey right around sunset. Brown must leave Faith behind while he goes on his adventure, by that Hawthorne means he not only leaves his wife behind, but also his spiritual faith. He travels through the forest which in itself is symbolism. He walks through the forest at night when it’s dark; Brown not having much visibility the further into the forest he goes is representing his confusion with life right now, not knowing where to go or what to do. Throughout the story, the forest grows darker and darker, representing God’s light fading away and Brown losing his faith. â€Å"The village is a place of light and order, while the forest is a place of darkness and unknown terrors. † (Xia-Chun) Brown then meets a man on his journey; this man is very influential in the story. The man is the devil carrying a staff that Hawthorne describes as serpent-like symbolizing the biblical reference of a serpent being an evil demon. In the Book of Genesis, the serpent is the main temptation Eve has to try the fruit of the forbidden tree. Similar to that, Goodman Brown accepts the devil’s offer of his staff, or serpent, in order to travel quicker. Brown fell under the temptation of the devil. The further into the forest Brown goes, the more he learns about his peers and elderly and the deals with the devil that they have made, thus causing Brown to lose faith. Once he is able to get back into the town of Salem, although he was able to resist the devil, he is still a changed man. Before his journey, he thought the world was a perfect place and no one was capable of hurting anyone or committing the act of sin. The relationship between Creator and creature, and between man and fellow man, is destroyed by sin†¦Ã¢â‚¬  (Fairbanks 25) After the journey, he realized that there is a lot of darkness and sin in the world and that more people than he realized were capable of unthinkable things and sinning in ways he never would have dreamt of. Hawthorne uses a good amount of symbolism in this story, most of it is obvious symbolism that he wants any reader to understand, not by analyzing deeply but just by having some common knowledge. Therefore, he uses imagery to really help the reader realize the symbolism he is implying. At the beginning of the story, Hawthorne notes that Brown is starting this journey right at sunset; the thought of sunset is considered light fading away and eventually becoming darkness. The use of this imagery provides the thought of symbolism that the young man is going into the unknown darkness and his light, which is a symbol also for his faith, is fading. Another good use of imagery is in the beginning of the story when Hawthorne writes â€Å"And Faith, as the wife was aptly named, thrust her own pretty head into the street, letting the wind play with the pink ribbons of her cap, while she called to Goodman Brown† (435). Hawthorne is using the wind to not only emphasize the pink ribbons Faith wears and help readers understand that those ribbons have meaning and is a symbol to her innocence, but also to explain the beauty of nature in Salem before his mind turns pessimistic and the town fades to darkness. Brown’s view of the town at the beginning before he was revealed all of the sin was a bright, pleasant town full of true-spirited people. The experience of this one night in the forest changes Goodman Brown for the rest of his life, for it poisons his relationship with his wife, isolates him from his neighbors, and destroys his ability to worship God. † (Easterly 55) After his trip with the devil, he was a changed man and saw the town with blackened eyes, only able to see the wrong in people and the capabilities of the devil. Hawthorne develops multiple themes during the story of Young Goodman Brown using the literary devices of symbolism and imagery. In telling the story of the journey Brown embarks on, Hawthorne brings the young man through the forest explaining to him that he is not the only one that has fell under the temptation of the devil and sin. For example, Goodman Brown looked up to his father and grandfather just as any young adult man would. When he was informed of the unimaginable thought of them making a deal with the devil: I have been as well acquainted with your family as with ever a one among the Puritans; and that’s not trifle to say. I helped your grandfather, the constable, when he lashed the Quaker woman so smartly through the streets of Salem. And it was I that brought your father a pitch-pine knot, kindled at my own hearth, to set fire to an Indian village, in King Philip’s war. (Hawthorne 436-437) The devil telling Brown about this was a surprise to Goodman because he always looked up to his father and grandfather and never imagined that either of them would be associated with the devil. The devil shows Goodman Brown the acquaintances, loved ones, public figures of the town who have all fallen into the devils trap and have sinned even when Brown looked up to them and thought none of them had evil in them. †¦young naive man who accepts both society in general and his fellowmen as individuals at their own valuation, is in one terrible night presented with the vision of human Evil, and is ever afterwards â€Å"A stern, a sad, a darkly meditative, a distrustful, if not desperate man†¦Ã¢â‚¬ Ã¢â‚¬  (Fogle 207) The unbelievable knowledge given to him led him into the devil’s trap and no longer saw the world as a pleasant place; he now only saw the evil in people. Just as anyone today would do, Brown fell under temptation and peer pressure and became a figure of sin. Hawthorne explains throughout the story about the temptations and peer pressure of evil that Brown faces. The thought of seeing childhood idols that were perfect in your mind involved in deals with the devil could lead you to feel differently about those people and question your own lessons learned from them. Seeing these people around you engaged in sin and falling into temptations brings a lot of peer pressure to you and leads you to rethink your lifestyle and make you vulnerable to doing things you wouldn’t normally. He explains that Christians lose faith easily and fall into sin through the story of young Goodman Brown using symbolism and imagery.

Vector And Raster Data In Gis Computer Science Essay

Vector And Raster Data In Gis Computer Science Essay A Geographical Information System (GIS) is a method of spatially storing, analysing, manipulating, managing and displaying geographical data. GIS data represents real objects such as roads, rivers, urban areas, place names, railway, places of interest, town names etc. with digital data determining the mix. A geodatabase is a database that is in some way referenced to locations on earth. Traditionally, there are two broad methods used to store data in a GIS; raster images and vector. Ordnance Survey Ireland (OSI) data is supplied in both Vector and Raster format. In both cases the data is geo-referenced. VECTOR AND RASTER DATA Vector data is split into three types; polygon, line (or arc) and point data. Vector is a method for storing spatial data involving assigning coordinates for each entity; an X,Y, Z for a point, a pair of such points for a line and a series of such lines for a polygon. This method is very useful for modeling discrete physical features. Different geographical features are expressed by different types of geometry: Points A point is a zero-dimensional abstraction of an object represented by a single X, Y co-ordinate. It is normally used to represent a geographic feature too small to be displayed as a line or an area (e.g. location of a building on a small scale map or, for example, cities on a map of the world might be represented by points not polygons). No measurements are possible with point features. Figure 1- Vector representation Source: http://www.geom.unimelb.edu.au/gisweb/GISModule/GIST_Vector.html Lines or polylines A set of co-ordinates that represent the shape of geographic features that are too narrow to be displayed as an area, such as, county boundary lines or contours. At small scales geographic features may have no area, e.g. streams or streets and may be represented as linear features rather than as a polygon. Line features can measure distance. Polygons Polygons are used to represent areas. Such as lakes, park boundaries or land uses etc. Polygons convey the most amount of information of the file types and can measure perimeter and area. Rigaux et al. (2002:p.38) states, A point is represented by its pair of coordinates, whereas more complex linear and surfacic objects are represented by structures (lists, sets, arrays) on the point representation. These geometries can be linked to a row in a database that describes their attributes. For example, a database that describes lakes may contain a lakes depth, water quality, pollution level. Different geometries can also be compared and the GIS could be used, for example, to identify all wells (point geometry) that are within one kilometre of a lake (polygon geometry) that has a high level of pollution. Vector data can be displayed at any scale and individual layers (e.g. roads, buildings, etc) can be displayed or omitted (see Appendix A). Raster Ellis states that raster is a method for the storage, processing and display of spatial data. There are three types of raster datasets; thematic data, spectral data and pictures. Raster data consists of rows and columns of cells, with each cell storing a single value. Raster data can be images containing individual dots with colour values, called cells (or pixels), arranged in a rectangular evenly spaced array. Each cell must be rectangular in shape, but not necessarily square (Ellis 2001). Each cell within this matrix contains location co-ordinates as well as an attribute value. The spatial location of each cell is implicitly contained within the ordering of the matrix, unlike a vector structure which stores topology explicitly. Areas containing the same attribute value are recognised as such, however, raster structures cannot identify the boundaries of areas such as polygons. Raster data is an abstraction of the real world where spatial data is expressed as a matrix of cells or pixels with spatial position implicit in the ordering of the pixels. With the raster data model, spatial data is not continuous but divided into discrete units. Ellis states that this makes raster data particularly suitable for certain types of spatial operation, for example overlays or area calculations. Raster structures may lead to increased storage in certain situations, since they store each cell in the matrix regardless of whether it is a feature or simply empty space. Additional values recorded for each cell may be a discrete value, such as land use, a continuous value, such as temperature, or a null value if no data is available. While a raster cell stores a single value, it can be extended by using raster bands to represent RGB (red, green, blue) colours, colour maps (a mapping between a thematic code and RGB value), or an extended attribute table with one row for each unique cell value. The resolution of the raster data set is its cell width in ground units. Anyone who is familiar with digital photography will recognize the Raster graphics pixel as the smallest individual grid unit building block of an image, usually not readily identified as an artifact shape until an image is produced on a very large scale (see Appendix B). A combination of the pixels making up an image colour formation scheme will compose details of an image, as is distinct from the commonly used points, lines, and polygon area location symbols of vector graphics. Aerial photographs and satellite images are examples of raster images used in mapping. Figure 2 Aerial Photo Digitally scanned and ortho-rectified raster colour photography. The ortho-rectification process removes distortions caused by camera tilt and topographical features to produce a scale accurate image. Source: OSI Raster data is stored in various formats; from a standard file-based structure of TIF, JPEG, etc. to binary large object data stored directly in a relational database management system. Raster v Vector There are some important advantages and disadvantages to using a raster or vector data model to represent reality: Vector graphics are usually more aesthetically pleasing. Raster data will appear as an image that may have a blocky appearance for object boundaries (depending on the resolution of the raster file). Vector data is simpler to update and maintain, whereas a raster image will have to be completely reproduced (e.g. a new road is added). Vector data allows much more analysis capability, especially for networks such as roads, rail, telecommunications etc. Distances and areas can be calculated automatically. With raster data it is difficult to adequately represent linear features depending on the cell resolution. Therefore, network linkages are difficult to establish. Vector files require less disk storage space than raster data. Raster data allows easy implementation of overlay operations, which are more difficult with vector data. Raster data structure allows simple spatial analysis procedures An outline of the application of vector and raster data by OSI in Ireland is included in Appendix C. Non-spatial data Relating the spatial component along with the non-spatial attributes of the existing data e.g. census figures (see Appendix D) enhances the users understanding and gives new insights into the patterns and relationships in the data that otherwise would not be found. Non-spatial data can be stored along with the spatial data represented by the coordinates of vector geometry or the position of a raster cell. In vector data, the additional data contains attributes of the feature. In raster data the cell value can store attribute information, but it can also be used as an identifier that can relate to records in another table. Software is currently being developed to support the solutions to spatial problems being integrated with solutions to non-spatial problems. This will result in non experts using GIS to integrate spatial and non spatial criteria to view solutions to complex problems and to assist in decision-making. Data capture The processes of data collection are also variously referred to as data capture, data automation, data conversion, data transfer, data translation, and digitizing. The two main types of data capture are: Primary data sources e.g. those collected in digital format specifically for use in a GIS project. Secondary sources, digital and analog datasets that were collected for a different purpose and need to be converted into a suitable digital format for use in a GIS project. For vector data capture the two main branches are ground surveying and GPS. Survey data can be directly entered into a GIS from digital data collection systems on survey instruments. Positions from a Global Navigation Satellite System like Global Positioning System (GPS), another survey tool, can also be directly entered into a GIS. New technologies allow creating maps as well as analysis directly in the field and as a result projects are more efficient and mapping is more accurate. Remotely sensed data also plays an important role in data collection and consists of sensors (e.g. cameras, digital scanners) attached to a platform which usually consist of aircraft and satellites. The majority of digital data currently comes from photo interpretation of aerial photographs. Workstations are used to digitize features directly from stereo pairs of digital photographs. These systems allow data to be captured in two and three dimensions, with elevations measured directly from a stereo pair using principles of photogrammetry. Photographs are collected by analog or optical cameras before being entered into a soft copy system, but as high quality digital cameras become cheaper this step will be eliminated. Satellite remote sensing provides another important source of spatial data. Remote sensing collects raster data that can be further processed to identify objects and classes of interest, such as forested areas. The disadvantages are that the resolution is often too course or sensors are restricted by cloud cover. Entering data into GIS usually requires editing, to remove errors, or further processing. For vector data it must be made topologically correct before it can be used for some advanced analysis. For example, in a road network, lines must connect with nodes at an intersection. For scanned maps, blemishes on the source map may need to be removed from the resulting raster. To ensure that the data is specific and reliable and that represents as closely as possible the spatial world we live in, it requires a quality insurance process to manage completeness, validity, logical consistency, physical consistency, referential integrity and positional accuracy of data. Raster-to-vector translation Vectorisation is the process of converting raster data into vector data. For example, a GIS may be used to convert a satellite image map to a vector structure by generating lines around all cells with the same classification, while determining the cell spatial relationships. One of the biggest problems with data obtained from external sources is that they can be encoded in many different formats. Many tools have been developed to move data between systems and to reuse data through open application programming interfaces. Therefore, a GIS must be able to convert geographic data from one structure to another. CONCLUSION When data is captured, the user should consider if the data should be captured with either a relative accuracy or absolute accuracy, as this could not only influence how information will be interpreted but also the cost of data capture. Vector data can be manipulated, layers can be turned on and off, data can be edited or deleted and additional data can be added in. Raster data is usually used as a background map. Raster is not as intelligent as Vector, Rigaux et al. (2002: p.39) states the structure is unfortunately not powerful enough to ensure the correctness of the representation. It is more useful as a display map for brochures, internet and power point presentations. Oosterom Van, P.J. (1993:p.vii) states the ever increasing availabilitiy of hardware such as digitizers, scanners workstations, graphic displays, printers and plotters for the input, processing, and output of geographic data only partly explains the growing interest in GISs. GIS allows us to view, understand, question, interpret, and visualise data in many ways that reveal relationships, patterns, and trends in the form of maps, globes, reports, and charts. GIS helps one answer questions and solve problems by looking at data in a way that is quickly understood and easily shared. Figure 3 GIS continues to evolve Source: Cummens 2010 ERSI Many forces are converging transforming how we work and improving efficiency and decision making (see Fig. 3 above). GIS Is becoming Mainstream Technology going beyond focused applications (Cummens 2010). GIS is helping citizens, business and Government by improving planning, management, communications and decision making.

Shape Memory Alloys Research

Shape Memory Alloys Research 1.1 General considerations When a regular metallic alloy is subjected to an external force greater than its elastic limit, it deforms plastically, i.e. the deformation persists after returning to the unloaded state. The Shape Memory Alloys (SMAs) do not follow this behavior. At low temperatures, an SMA specimen may undergo a plastic deformation of about few percent, and then fully recover its initial shape that had at higher temperature by simple heating above a threshold temperature. Their ability to recover their form when the temperature is raised, makes this class of materials unique. This phenomenon has been discovered in 1938 by researchers working on the gold-cadmium alloys [Gilbertson (1994)]. The shape memory effect remained a laboratory curiosity until 1963, when the first industrial and medical applications appeared. 1.2 Martensitic Transformation The shape memory effect is based on the existence of a reversible phase transformation of thermoelastic martensitic type [Kurdjumov, Khandros (1949), Kumar, Lagoudas (2008)], between a microstructural state at high temperature (austenite phase) and a microstructural state at low temperature (martensite phase) [Patoor et al. (2006), Lagoudas et al. (2006)]. Austenite has in general a cubic crystal lattice, while martensite is of tetragonal, monoclinic, or orthorhombic crystal lattice. The transformation from one crystal lattice to the other occurs by distortion of the shear lattice does and not by atoms diffusion. This type of transformation is called martensitic transformation [Perkins (1975), Funakubo (1987), Otsuka, Wayman (1999)]. In reality, the matrenitic transformation in SMAs is a phase transformation of the first order, where there is co-existence of several phases, and there is presence of interfaces between the phases [Guà ©nin (1986)]. Historically, the term martensitic transformation describes the transformation of the austenite of steels (iron-carbon alloys) to martensite during a quenching. By extension, this term has been generalized to a large number of alloys whose phase transformations have certain characteristics typical of the transformation of steels [Rosa (2013)]. During martensitic transformation of a SMA, the crystal lattice of the material changes its shape. The microstructure of martensite is characterized by a change in shape and by the difference in volume, which exists between matrensitic and austenitic phase [Duerig et al. (1990)]. Therefore, internal strains arise during the emergence of martensitic areas within the austenite. The internal strains can be partially relaxed by the formation of several areas of self-accommodated martensite crystals that minimize the overall deformation induced. These areas called variants and are oriented in different crystallographic directions [Kumar (2008)]. In the absence of external strains, these variants are equally possible and the distribution of self-accommodated groups allows the material to be transformed in order to retain its original shape. Therefore, the formation of the martensite results in elastic (reversible) deformations [Funakubo (1987)]. At constant temperature, the martensite-austenite interfaces are in steady state. A change in temperature in one direction or the other results in moving these interfaces to the benefit of one or the other phase structure. The interfaces can also move under the action of an imposed strain. A specimen can therefore be distorted not by sliding, which is the usual mechanism of plastic deformation, but by the appearance and disappearance of martensite variants [Kumar (2008)]. Therefore, during martensitic transformation atoms in the structure move on very small distances leading to deformation of the crystal lattice. This causes a small variation in volume with shearing of the structure in a specific direction. During the transformation process, the growth of martensite crystals occur in form of platelets to minimize the energy at the interface. The martensitic variants can occur in two different types: twinned martensite (formed by combination of self-accommodated martensite variants) and detwinned martensite (reoriented martensite) where a particular variant dominates [Liu, Xie (2007)]. The characteristic behavior of SMAs is based upon the reversible phase transformation from austenitic phase to martensitic phase and the opposite. By cooling under zero loading, the crystal sructure changes from austenitic to martensitic phase (forward transformation to twinned martensitic phase). This transformation is resulting in the development of a number of martensitic variants, which are arranged in a way that the average change in macroscopic shape is insignificant, causing a twinned martensite [Leclercq, Lexcellent (1996)]. When the material is heated at the martensite phase, the crystal structure is transforming to austenite (reverse transformation from detwinned martensitic to austenitic phase), leading to recovery of shape [Sabu ri, Nenno (1981), Shimizu, Otsuka, Perkins (1975)]. The above process is called Shape Memory Effect (SME) [Schetky (1979), Wayman, Harrison (1989)]. The martensitic transformation is characterized by four temperatures (Figure 2) [Gotthard, Lehnert (2001)]: MS: Temperature below which the martensite appears (martensite start) MF: Temperature below which the entire sample is transformed into martensite (martensite finish) AS: Temperature above which the austenite appears (austenite start) AF: Temperature above which the entire sample is transformed into austenite (austenite finish) The transformation begins at the cooling to the temperature MS. This transformation is completed to the temperature MF. Between these two temperatures, there is coexistence of two phases, which is a characteristic of transformation of the first order. If the cooling is interrupted, the material will not change. To go back to the initial shape, the temperature is increases so that the inverse transformation begins at the temperature AS and finishes to temperature AF, which is higher than MS [Massalski et al. (1990)]. If the trace on a diagram (Figure 1) the volume fraction of material processed as a function of temperature, there is a hysteresis loop, due to the presence of an irreversible energy corresponding to dissipation of mechanical energy transformed into heat [Ortin, Planes, Delaey (2006), Wei,Yang (1988)]. Figure 1 Martensitic transformation temperatures [Gotthard, Lehnert (2001)] The thermoelastic reversibility of the crystal lattice is certain in the case of an ordered alloy [Otsuka, Shimizu (1977)]. The correlation between the manifestation of martensitic transformation and atomic order was shown experimentally in Fe-Pt SMAs [Dunne, Wayman (1973)]. Nevertheless, in disordered alloys, such as Fe-Pd, Mn-Cu and In-TI, can occur thermoelastic transformation too. The atomic order is, therefore, a sufficient condition for manifestation of thermoelastic transformation, but not necessary [Otsuka, Shimizu (1977)]. 1.3 Thermomechanical properties of SMAs Several effects specific to the SMAs appear through the transformations of the crystal lattice as a function of temperature and of the field of stresses applied on the material [Duerig, Melton, Stà ¶ckel (2013)]. 1.3.1 Pseudoelastic Effect In general, by pseudoelasticity we describe both the materials superelastic behavior, as well as rubble-like behavior. Superelastic behavior is called the reversible phase transformation produced by thermo-mechanical loading. Rubber-like effect refers to the reversible martensitic re-orientation. The stress-strain curve during this process resamples to the superelastic behavior, which is similar to rubbers nonlinear elastic behavior [Otsuka, Wayman (1999)]. Therefore, a part from inducing phase transformation thermally, martensitic transformation can also be prompt by applying on the material appropriately high mechanical loading, resulting in creating a martensitic phase from austenite. When the temperature of the SMA goes above AF, shape recovery is resulted while unloading. Such behavior of the material is termed pseudoelastic effect [Kumar (2008)]. Stress-induced martensite, is generally forming from austenite when external stress is present. The process of forming stress-induced martensite can occur through different thermomechanical loading routes [Miyazaki, Otsuka (1986)]. One form of stress-induced martensite is the detwinned martensitic phase formed from austenitic after application of external stress. The material, during the stress-induced martensitic transformation and the reversed process, shows nonlinear elastic behavior described by closed à Ã†â€™-ÃŽÂ µ curves. This nonlinear elastic behavior is called pseudoelastic transformation [Otsuka, K. and K. Shimizu (1981)]. The shape recovery is due to crystallographic reversibility of transformation, like in the shape memory effect. Hence, the two phenomena, transformation pseudoelasticity and shape memory effect are practically the same except the fact that reverse transformation is produced by warming the specimen to temperature above AF. In reality, an alloy that un dergoes thermoelastic martensitic transformation exhibits both transformation pseudoelasticity and shape memory effect [Otsuka, K. and K. Shimizu (1981)]. Nevertheless, for occurring transformation pseudoelasticity, the necessary stress for slip should be greater than that for stress-induced martensite transformation. As an example, we can refer to equiatomic Ti-Ni alloys which are exposed to slip and do not exhibit any transformation pseudoelasticity, regardless of their Ni content. It was shown, however, that Ni-rich Ti-Ni alloys subjected to annealing after cold working, causing refining of their grain size, leads in raising critical slip stress, which results in any transformation pseudoelasticity [Miyazaki et al. (1982), Saburi, Tatsumi, Nenno (1982), Saburi, Yoshida, Nenno (1984)]. The existence of transformation pseudoelasticity is affected by crystalline orientation, composition of the alloy, and direction of applied stresses [Miyazaki, Otsuka (1986)]. 1.3.2 One-Way Shape Memory Effect Another property of SMAs is the one-way shape memory effect. It takes place in four steps: (1) The material is cooled to a temperature lower than MF (the parent austenitic phase) to obtain self-accommodated martensite. (2) Re-orientation of variants of the martensite is obtained via application of stress. (3) The stress is released at constant temperature T F. The material remains to a shape depending on the stress field. (4) The sample is heated at a temperature T > AF making re-appear the austenitic phase and the material gets its original shape, as shown in Figure 2. Figure 2 One-way shape memory effect [Miyazaki, Otsuka (1986)] Two conditions are necessary for occurring shape recovery by shape memory effect. Firstly, the transformation should be reversible, and second, slip should not occur during the entire deformation process. Martensitic transformations in ordered alloys are reversible in nature [Miyazaki, Otsuka (1986), Arbuzova, Khandros (1964)], so the entire shape memory effect mainly occurs in this type of alloys. The second condition is necessary because in the case of high stress and every type of deformation mode (stress-induced martensitic transformation in parent phase, twinning in the martensitic phase) slip can be induced, resulting in plastic strain and, not completed recovery of shape. In the one-way shape memory effect, the shape in memory by the SMA is the one of the parent phase. 1.3.3 Two-Way Shape Memory Effect The two-way shape memory effect is the reversible passage of a shape at a high temperature to another shape at low temperature under stress. The two-way shape memory effect should precede the SMA training [Nagasawa, et al. (1974]. Training of SMAs consists of temperature cycling at constant stress or stress cycling at constant temperature. During training, microstructural defects (i.e. dislocations) lead to internal stresses and therefore promote oriented martensite. A SMA subjected to training can then move from austenitic phase to oriented martensite under zero load by simple change of temperature [Schroeder, Wayman (1977)]. It has then a shape in memory for each of the two phases. Various methods that cause two-way shape memory effect have been suggested, such as, large deformation in stress-induced martensite transformation at temperatures > MS [Delaey et al. (1974)], shape memory effect training [Schroeder, Wayman (1977)], stress-induced martensite training [Schroeder, Wayman (1977)], training involving both of shape memory effect as well as stress-induced martensite [Perkins, Sponholz (1984)] remaining in martensite state while heating at a temperature > AF [Takezawa, Shindo, Sato (1976)], as well as using precipitates [Tadaki, Otsuka, Shimizu (1988)]. 1.4 Transformation Induced Plasticity (TRIP) Several experimental studies have shown the development of nonlinear plastic (irreversible) strain when phase transformations occur [Greenwood, Johnson (1965), Abrassart (1972), Magee (1966), Desalos (1981), Olson, Cohen (1986), Denis et al. (1982)]. This mechanism of deformation is termed Transformation Induced Plasticity (TRIP), resulting from internal stress rising from the change in volume related to the transformation, as well as from the associated change in shape [Marketz, Fischer (1994)]. TRIP differs from classical plasticity. Although plasticity is caused from the applied stress or variation in temperature, TRIP is triggered by phase variations, and occurs even at low and constant stress levels [Gautier et al. (1989), Leblond et al. (1989), Gautier (1998), Tanaka, Sato (1985), Fischer et al. (2000, 1996)]. TRIP takes place because of two separate mechanisms. The first, refers to a process of accommodation of micro-plasticity related to volume change [Greenwood, Johnson (196 5)]. The other, refers to an orientation caused by shear internal stresses, favoring the direction of preferred orientation for the formation of martensite when and external stress is present, which involves change in shape [Magee (1966)]. TRIP is caused by the difference in compactness of the lattice structure between the austenite (parent) and the martensite (product) phase [Greenwood, Johnson (1965)]. During martensitic transformation, this difference has produces a change in volume as well as internal stresses causing plasticity in the phase with less yield stress, which is weaker   [Paiva, Savi, Pacheco (2005)].

Conformity:The Greek Society Essay -- essays research papers

Conformity: The Greek Society   Ã‚  Ã‚  Ã‚  Ã‚  Conformity, on a daily basis we conform to the social norms set forth before us by our friends, family and past experiences. Group cohesiveness (the desire to which one has to be in and is attracted to the group) greatly increases conformity. Enter Greek life.   Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  We have all seen them, parading down the halls, across campus, and in the Student Union. Strutting around with their number one symbols of pride across their backs or chests, on a sleeve, a pin or hat, GREEKS. Going Greek is a social decision as one enters college. You either are or are not a Greek, which creates a rather noticeable IngroupOutgroup situation, and millions of stereotypes between both Greeks and Independents.   Ã‚  Ã‚  Ã‚  Ã‚  To some Independents, Greeks are seen as followers, conformists, who joined simply to ?buy their friends? and some Greeks see Independents as ?GDIs (God Damned Independents, for lack of better definition), people who are losers because they won?t join, for whatever reason.

It is very simple to see who is part of the group and who is not. It is pretty obvious from the blaring letters, ringing chants, songs, and stories that you are part of the group. From the Greek point of view there are 3 types of groups, Fraternity Men& Sorority Women, Pledges, and everyone else. You are either in or out it is that, plain and simple. You have either chose to conform to the ideals of your perspective organization or you have chosen not to be a part.   Ã‚  Ã‚  Ã‚  Ã‚  There are sub divisions of the In-group, as far as the different organizations; you are a Sig-Kap, TKE, Skull, AST, etc. This is turn creates In-groups amongst the In-group.

Which is a predominate theme in IngroupOutgroup Theory.   Ã‚  Ã‚  Ã‚  Ã‚  Greeks call this ?pride?, conforming to these beliefs is part of the whole Greek concept.

An Analysis of Joyce Carol Oates’ Where Are You Going, Where Have You

An Analysis of Joyce Carol Oates’ Where Are You Going, Where Have You Been Joyce Carol Oates is one of the most productive writers of our time. Between 1971-95, Oates published twenty-five novels, eighteen short story compilations, three collections of novellas, five volumes of poetry, six editions of plays, eight books of essays, and countless more umcollected works (Kellman 487). As the format for her writing varies, so does her subject matter. Her creations cover a wide range of genres, but Oates' main fascination is contemporary America with its "colliding social and economic forces, its philosophical contradictions, its wayward, often violent energies" (Johnson 8). Oates' works, and somethimes even Oates herself, have been subject to responses ranging from extreme praise to harsh criticism from the literary community. Oates has won many significant literary awards and has even been nominated twice for the Nobel Prize in literature but has also received her share of bad press. Oates' work has time and time again been criticized for being too violent, to o bizarre, degrading to women, and "the exact antithesis to the feminist movement" (gtd. in Wesley par. 32). I believe the opposite is true. Oates herself has been quoted as saying that her subject matter is "today's culture," and that all she is trying to do is to bring the ills of our cuture "to a place where it can be examined" (Johnson 10). Some of her stories are purely fictional, but many stories seem to be ripped from the headlines. Zombie, a 1995 novel, is loosely based on the Jeffrey Dahmer serial killings (Seltzer 288). The highly acclaimed short story "Where Are You Going, Where Have You Been?" draws its inspiration from the case of an Arizona serial killer,... ...arterly Review 38 (1999): 487-495.

Podcast on Power and Control in the Book

Good Afternoon Ladies and Gentlemen and Welcome to Connections in English. I am Frank Weng your host for this podcast series. Today’s topic we discuss the relationship of Power and Control between the novel of One Flew Over the Cuckoo’s Nest and the film 1984. Power and Control is a strong element within everyday life and is also deeply touched on in the novel One Flew Over the Cuckoo’s Nest and the film 1984.Power and Control is defined as being able to perform and act efficiently with a dominating influence over a population, this theme is not just an element within a story but an issue that is met in everyday life, however Power and Control is heavily related to this particular novel and film for example, the view of a leader taking power all those around them, a person who has complete and utter control of their surroundings due to an elevated status or ability, this can be seen by both big brother in 1984 and nurse ratchet, or the big nurse in one flew over the cuckoo’s nest.The need to control all thought, eliminate any individuality and have all subjects thinking in a similar way, this is present in both texts with the person in control again being nurse ratchet and big brother/ the government Everyone you see has a glint of Power & Control, as going through school you meet bullies who are generally bigger and physically stronger than others, however it isn’t just physical strength. One could have a higher status in society (higher reputation) than others therefore have potential of grasping significant power and control.There are even individuals in this society who are born into a family with heavy power and control, The Mafia is a good example, Role models are depicted upon and are favored toward the person in control. Never the less you may never constantly maintain your power and control, the loss of power comes with the consequence of losing control. The Classic American novel One Flew Over the Cuckoo’s Nes t written by Ken Kesey has the aspect of Power and Control heavily impacted into the novel.The Chief is the narrator of the novel and he perceives the ward as a system, however he does not speak and pretends to be deaf â€Å"I had to keep on acting deaf if I wanted to hear at all† this shows personal control over himself. However, Nurse Ratchet or The Big Nurse is the head of the system in the ward as even doctors cannot control her. Harding quotes â€Å" We are victims of a matriarchy here, my friend, and the doctor is just as helpless against it as we are†. This clearly shows the loss of authority and control of doctors to Nurse Ratchet nd how she is in control of the system. However, in order for this system to work and maintain, she creates her routine that is never changed, that is until McMurphy is put into the ward. McMurphy is the one who can escape the ‘system’ and takes personal control, he demonstrates the possibilities the ward members can do a nd encourages them to look beyond the controls imposed upon them and wants them to have fun to feel competent and able to achieve things in the world.An example of this is when McMurphy Sneaks out with the ward members and takes them to the docks and steals the boats and go out to sea to go fishing also allowing one of the ward members to take control over the boat. It seems that the sense of own power and control gives happiness and cures their issues, an example of this is when Billy had spent the night and slept with McMurphy’s friend, as of this he began to stutter less. However Nurse Ratchet using her power and manipulates Billy’s mind ended with the result of him killing himself.Chestwick says â€Å"she grinds our noses in our mistakes† showing the authority and power of the Big Nurse. 1984 directed by Ridley Scott, Novel written by George Owell is the Big Hit Film that has the topic of Power and Control which is closely related to One Flew Over the Cuckoo ’s Nest. It is set in the post war England and it Expresses & maintains Power and Control through the use of fear, physical abuse, and threat of an imaginary war and the use of the new speak. War is Peace, Freedom is slavery, Ignorance is Strength† This is the slogan of the party which is saying that having a common enemy keeps the people of Oceania united, those who are independent are doomed to fail and inability of the people to recognize these contradictions cements the power of the authoritarian regime. Winston works at the Ministry of truth, this is where all of history is kept and saved and is changing history to reflect their current ideology of the party.The creation of new speak is to control the way they spoke used to prevent people from conceding any disobedient thoughts against the party and individual thoughts and ideas. â€Å"Never again will you be capable of ordinary human feeling. Everything will be dead inside you. Never again will you be capable of love, or friendship, or joy of living, or laughter, or curiosity, or courage, or integrity. You will be hollow.We shall squeeze you empty and then we shall fill you with ourselves† This is the main and most visible way through the film of power and control through the minister of Love, ironically this is where the party conducts their torture, mind controlling and brain washing to rehabilitate the misguidance of the citizens of Oceania. After Winston came out of room 101 â€Å"He gazed up at the enormous face, forty years it had taken him to learn what kind of smile hid behind the dark mustache.Two gin scented tears trickeled down his face, but it was alright, everything was alright, the struggle was finished. He had won the victory over himself. He loved big brother†. Another clear way that is shown of control is how large screens of big brother are placed everywhere which is the perception of big brother always watching. Power and Control is a powerful aspect and can be used to manipulate others without realization. One flew over the cuckoo’s nest and 1984 is clearly shown of power and control both similar and both different.

Internet And Culture

Discoveries and innovations in technology have directly and indirectly brought about profound changes in most basic institutions, social groups, worldviews and human values, ethical issues, the character of everyday life, and ways and means of satisfying human needs and international relations in modern society. Yet, the technological element which could be said that has deeply penetrated both the developed and developing nations of the world is the internet, bringing with it changes towards a more fluid flow of different cultures.The accessibility of the internet enables the differences and complexities mongo cultures to be presented to the world and be understood. If long ago, traditions of some ethnic minorities and far-flung societies were unknown, people nowadays could have a glimpse of what is happening at the other side Of the globe. This proliferation Of information and knowledge is one of the benefits of the internet phenomenon since people are no longer ignorant of the intr icacies among cultures.Moreover, biases and prejudice are reduced because people can have the chance to comprehend the rationales behind some traditions and rituals that they might find strange and disturbing. Other than this, the internet also made way for the fusion of cultures as one internet user may acquire the habits, literature, and entertainment of other countries. Transferring of cultures is not actually rare in mankind's history. A civilization adapts to the culture of its predecessor, and a group of people borrows some elements from another race, at the same, combining it with their existing culture.The Romans had done this with the Hellenic culture, and colonized countries gained the influences from their colonial masters while retaining their indigenous culture. Hence, it is not only technological knowledge itself that is being transferred and exchanged in the internet but also cultures, traditions, and ideas. In line with this is the advent of popular culture that seem s to transgress every culture and race in the world. Popular culture is a micro-culture that exists within the spheres of the World Wide Web.It is no question that popular music, movies, fashion and literature are consumed more by the youth than any other age group. The young people appear to agree on what is â€Å"in†, who is to follow and what will be the next â€Å"it† thing. Moreover, Hough culture has long been thought as heterogeneous, encompassing various races and groups, the internet made the world to look like just one big community of people hooked on the wires of social en;irking, files sharing and online gaming.There has indeed emerged a new culture entirely different from the previous cultures created before the invention of the internet. The World Wide is actually a huge community, bigger than any other existing or past communities in human history, which has developed its own culture, language and identities. Only entities would understand what â€Å"1 01† means, how to â€Å"tweet', or what makes Faceable so popular. Furthermore, the internet community acquired a voice that is able to spread information and news so quick that a world leader would resign from just a clamor from the internet users.However, as much as the internet culture has become a good vehicle for change, it has also become a mode for destroying one's life by just one click. No other culture could be as unforgiving and as offensive as the culture in the internet. Internet culture also does not respect privacy and intellectual property. Music and videos are illegally downloaded and private pictures loud be shared to almost anyone.Actions allowed by technology precipitate conflicts in values, yet these values seem to be disregarded on the internet, whatever culture one may belong. Technology, specifically the internet, has contributed largely not only to the shaping of the world in which we live but also to the modification, creation and transfer of culture s. Its influences and impacts are all pervasive. Therefore, the intimacy with and the dependence on this technology in our lifestyles and culture are expected to become stronger in the future.

Four Freedoms Essay

The poster that I chose to do my analysis on is by Adam Lewin. His art is modern and is representative of current events. He is an illustrator and an art director. He has studied at the Pratt Institute, the Gerrit Rietveld Academie in Amsterdam, and New York University (http://www. thoughtsondemocracy. blogspot. com/ 2009). The poster is representational of what is currently happening in American culture today. Lewin’s poster persuades me not to want to live in the United States anymore. His poster depicts our freedoms being taken away from us. The â€Å"Freedom of Speech† picture persuades me not to want to protest. It conveys to me that if we go out into the streets and exercise our freedom of speech we will be gagged and hauled off to jail. The Police in the poster look menacing and colossal, and the protester looks small and meager. The â€Å"Freedom of Worship† poster persuades me not to tell anyone what religion I am for fear that I may get killed, for not being the right religion. The man looks as though he is lying on a gurney and has been shot dead because he was worshiping to the wrong religion. Lewin’s â€Å"Freedom From Want† reminds me that we should not feed our children McDonald’s. Children know what the golden arches mean before they can even read. The fast food industry has made Americans huge. The little boy in the picture has a super-size coke in front of him, and he looks like he is pointing to get some more food, which he clearly does not need. This persuades me that there is no freedom from want because Americans are gluttons. They want as much as they can possibly acquire to fill them up emotionally. Lastly, â€Å"Freedom From Fear† persuades me not to want to break any laws (running a red light, talking on cell phone while driving) big brother is always watching us especially at every stop light. On the positive side it might make some people feel safe and might deter a criminal from committing a crime. Lewin’s and Rockwell’s posters look completely opposite from each other. Rockwell’s poster is indicative of what the people looked like in the 1940’s (wholesome). It seemed to be a more innocent time, but it wasn’t. Rockwell was painting an ideal instead of reflecting a reality. Whereas, Lewin is doing the opposite, he is reflecting the reality of the current American way of life. However, there are many similarities between the two pictures. In Rockwell’s â€Å"Freedom of Speech† painting it looks as though the people in the painting are giving the man respect and listening to what he has to say. However, I read that these men did not agree with what this man was saying. Therefore, it relates to Lewin’s poster because both these men are being degraded for speaking their minds. Also both men look like they are from the working class. The religion that I saw represented in Rockwell’s â€Å"Freedom of Worship â€Å"is Christianity. Thus the painting failed to represent multiple religions. This relates to Lewin’s poster because in my opinion Lewin’s poster is suggesting that the man in the picture is dead. This suggests that the predominate religion of the 1940’s (Christianity) is dying. practicing one Also people should have the right to practice any religion they want as FDR suggested in his speech. Lewin’s and Rockwell’s â€Å"Freedom FromWant† relate because neither of these scenes are lavish and the food seems to be the focal point. Also, the elderly woman seems to be the one serving everyone and the boy in the picture is pointing as though he is waiting for someone to serve him or give him more food. Although these two pictures look completely different they relate to each other in the same way. They both depict safety and security. When I was a little girl my mother use to tuck me into bed every night and this made me feel safe as the mother and father in the Rockwell painting are doing to their children. The man is holding a paper which tells of the horrors going on overseas. They are protecting their children from the evils of the world and easing their young minds. I think that Lewin’s depiction of the cameras eases the American people’s minds or maybe the powers that be. Surveillance cameras may help catch criminals or even terrorists. The poster, which depicts four separate themes, will be shown to reflect contemporary understandings of democracy and the democratic system in operation. The theme in the upper left hand corner under â€Å"Freedom of Speech† depicts a young man being dragged by two police officers. Although our Constitution guarantee’s freedom of speech, nevertheless the arrest of this young man portrays what occurred recently when the Wall Street protesters gathered peacefully in front of the New York stock exchange, yet they were arrested and thrown in jail for disturbing the peace. However, what they were actually doing was exercising their first amendment rights of free speech. The second image on the top right hand corner under â€Å"Freedom of Worship† depicts a dead person. Unfortunately this depiction is very true in today’s society. We are constantly informed of suicide bombers in Afghanistan, Pakistan, and Iraq who , in the name of religion, strap bomb belts on themselves and blow themselves up in mosques and other places where their co-religionists ( of different sects) are worshiping. It also suggests to me that the practice of one religion in the United States no longer exists. Since there are people from all over the world living in the United States we have an array of different religions. The third image on the bottom left hand corner under â€Å"Freedom of Want† depicts a young man pointing to a half empty glass. This expresses the current division in contemporaneous society of the haves and the have not’s. This young boy seems overweigh and is probably a member of the have not’s. I say this because insufficient funds results in poor eating habits, such as overindulgence of processed foods. The final image on the lower right hand corner under the caption â€Å"Freedom from Fear† depicts an array of surveillance equipment. Thanks to the increased awareness of crime coupled with modern high technology, these surveillance cameras are designed to catch criminals in the act of committing a crime there by resulting in quicker arrests and convictions, and possibly preventing the crime from being committed in the first place. Surveillance cameras which were installed in all entrances to the London underground have effectively prevented a repeat of the 2005 underground bombings. Therefore commuters have no fear using the â€Å"tube† and are thus free from fear, exactly as the artist intended to demonstrate.
