Psychological Definitions of Abnormal Behavior Essay

According to the science of psychology one’s behavior needs to follow a certain criteria in order to be deemed â€Å"normal†. If one’s behavior does not match the criteria, their behavior is seen as undesirable and wrong (requires change). For this physiologists need to be able to view a person’s behavior and be able to tell the difference between normal and abnormal. Whilst defining the â€Å"normality† of ones behavior physiologists need to be careful to remain objective and as free of any bias as possible, furthermore their experiment to determine ones behavior needs to be repeatable and reliable. In order to do this psychologists often consults the characteristics of ideal mental health proposed by Marie Jahoda in 1958. Marie Jahoda proposed 6 different characteristics for ideal mental health after surveying different doctors and psychologists; this is the list she came up with: * Positive self esteem and a strong sense of identity * Personal growth and development * Ability to cope with stressful situations (integration) * Autonomy and independence * Accurate perception of reality * Successful mastery of the environment, particularly relationships. Jahoda argued that if one does not meet these criteria then ones behavior can be deemed abnormal as a result of an existing problem. This in my opinion provides a strong applicable foundation for the determination of ones â€Å"normality† of behavior. However the problem with Jahoda’s ideal mental health scheme is the fact that the results obtained rely solely on the observer’s judgment, therefore presenting a inevitable bias not to mention the fact that no person can truly ever meet all of the suggested criteria. This mean that according to Jahoda every person is abnormal. Another way to look for abnormal behavior for psychologists is to find deviation form the social norm (majority). This is done by observing ones actions in public and seeing how normal it is. For example if you see someone wearing a bikini/swim trunks whilst walking around a supermarket, his or her behavior would be deemed as abnormal. The limitations of observing behavior in this manor lay in the fact that different cultures have different norms. Not to mention the fact that in any given culture norms evolve. What may have once been acceptable in the 80’s is not necessarily acceptable today. Abnormality of one’s behavior can also be monitored by looking at its statistical frequency. Meaning how common ones behavior is when compared to the rest of the public. If one’s behavior is shared by many it is deemed common and therefore â€Å"normal†, however if ones behavior is uncommon or rare, it is deemed abnormal. For example one may say that an individual who has an IQ below or above the average level of IQ in society is abnormal. The problem with this system is the fact that, it does not account for the desirability of the given behavior. In other words this system claims that both low and high IQ’s are an abnormality that need to be treated. Physiologists and others interested in â€Å"normality†, look over at ones behavior to see how well they can function. If one is unable to function adequately they are deemed abnormal. In order to determine how well one functions, psychologists consult Rosenhan and Seligman’s list of characteristics that define abnormality (1989). Rosenhan and Seligman argued that in order to classify someone as â€Å"inadequate in life† they must meet several of the characteristics as a pose to only one. This is their list: * Suffering * Maladaptiveness (danger to self) * Vividness & unconventionality (stands out) * Unpredictably & loss of control * Irrationality/incomprehensibility * Causes observer discomfort * Violates moral/social standards The possible limitation to Rosenhan and Seligman’s list of characteristics is the fact that â€Å"normal† people engage in activates which are potentially harmful like drinking or smoking, these people are not classed as abnormal. It is very difficult to classify behavior as to date no scheme to do so exists, which is perfect. Physiologists must tread carefully when labeling one with a disorder. Bias will always be present in one form or another, however the results can be deemed reliable if practicing psychologists consult multiple schemes in order to have a better chance of an accurate diagnosis.

Bend It Like Beckham

Field Experience A feedback on the movie â€Å"Bend it like Beckham† ——-From the perspective of Cross-cultural communication : : :201120327 :2011? 10? 11? A feedback on the movie â€Å"Bend it like Beckham† ——-From the perspective of Cross-cultural communication Abstract: Based on the English movie â€Å"Bend It like Beckham†, this paper is going to reveal the cultural phenomenon hidden in this story. Divided into three parts, this paper mainly makes an analysis on two aspects, one is religion, and another is family culture.Finally, the author points out: it is very important for people of different cultures to understand and respect each other. Thus, a peaceful and harmonious world would be around us! 1. Introduction and analysis of the movie: Before the 1980s, African culture and Asian culture got terrible restriction in UK, however, after the 1980s; a large number of movies that describe immigrants’ life have emerged in f ilm industry in England. Bend It like Beckham† is such a movie, which borrows cultural and racial difference between England and India, reflects how the two cultures co-exist and accept each other in a hard procedure As the immigrant of the second generation, Jess, a girl with talent to be a football player, shows her great admiration to Beckham,hoping, one day, she can play for England with Beckham shoulder by shoulder, while her mother believes that Jess has two great duties in life: to learn to prepare a complete Indian meal, and to marry a nice Indian boy.However, Jess never wants to be a housewife who can only cook. Jess’ love of soccer crosses over into a love of life. She runs onto the field as if simply at play, in her eyes’, football is not one part of aboard culture,but a natural thing in her living environment,however, it was not included in her clan and family culture,therefore, what she has to confront is the strait of the cultural conflicts caused b y two co-existing culture. In fact, â€Å"Bend It like Beckham† is a product of cultural clash.One day, Jess was playing soccer with boys in the park; Of course, an Indian girl should not play soccer at all, since in her mother's mind the game consists of â€Å"displaying your bare legs to complete strangers. † Jess is seen in the park by Juliette, who plays for the Hounslow Harriers, a woman's team, and is recruited to join them. The coach is a young Irishman named Joe. Although she deceives her parents about her join into the football team, she loves them and understands their point of view.The cultural conflict is still upgrading when Jess falls in love with her coach,, which is undoubtedly an earthquake for Indian family, but, at the end of this movie, we can feel hope, the two family members shake their hands together, and Jess’s boyfriend begin to play cricket together. It seems that, English people are being accepted by Indian family. And the old Indian p eople get out from the dark shadow in their heart. Historically speaking, India was the colony of England for a long time, English people usually were gentlemen, but they look down upon Indian people.Jess’s father was a excellent cricket player, owing to cultural diffusion,he lost the chance to play cricket , fortunately, Jess got her family’s support and realized her father’s dream. Then, in the following part, I will give a detailed analysis about cultural differences under the influence of two different tradition and religion, 2. Cultural analysis 2. 1. Culture and family Although, a culture’s core values and world view derive primarily from its predominant religious view and cultural history, the family is the primary caretaker of these views and values and transmits them to new members of the culture.In this story, there are two families, the representatives of the two cultures, one is the ordinary England family, observed from the surface, and it is an open, modern, and fashioned family. However, In this story, Juliette’s mother misreads Jess and Juliette’s friendship as lesbian, so painful that she cried secretly, according to her attitude toward lesbian, we will realize English people is conservative in soul. The other one is an emigrate family from India, Indian parents are strict and traditional, they have strong religious belief. Which indicate what kind of Jess’s family is.As expected, it is incredible and unsupportable for a girl playing football. Family gives children knowledge about their historical background, information regarding the permanent nature of their culture, and specific behaviors, customs, traditions, and language associated with their ethnic or cultural group. In short, the family tells us, and others, who we are and what groups we are part of. ( K. A. Ocampo, 1993, 106). So next, I will render the different interaction pattern in English family and Indian family from two aspects: g ender role and individualism- collectivism 2. . 1. gender role In India, males are usually considered the superior sex, as Samovar points out, men make most of the important decisions, inheriantance is through the male line, and a woman lives in her husband’s village after she marries. (Samovar, 2000,). Therefore, in India, boys give much freedom of expression than the girls, and girls are asked to help with the chores that keep the family functioning. However, in British, women usually have the equal right as man does in family life, even in social activity. 2. 1. 2. ndividualism and collectivism Individualism and collectivism are learned through the family, which teaches children whom they must obey and who the dominant figures are in their life. In this movie, the Juliette from English nuclear family is much more self-reliant and self-responsible than Jess who from Indian Family, because, India is a typical country of extended family, people in India, share property, all m aterial possession, food, work and love, perform religious rituals together, and often live under the same roof.There is a scene in this movie: when her sister’s would-be parents-in-law discovered her intimate behavior with Juliette whom was mistaken for a English boy,. Just because of Jess’s so-called â€Å"shameful behavior†, they break off her son’s engagement with Jess’s family according this story, it’s not difficult to get conclusion that India family is a typical collectivism; one people’s thing is the thing of the whole family. 2. 2. Culture and Religion: In this movie, you will find lots of religious elements in the story, to some extent, cross-religious communication is the cross-cultural communication. When religion jumps to life it displays a startling quality. It takes over. All else, while not silenced, becomes subdued and thrown into a supporting role†¦It calls the soul to the highest adventure it can undertake, a proposed journey across the jungles, peaks, and deserts of the human spirit (H. Smith, 1991, P9). So, from different religions, we can understand different people’s spiritual and psychological needs or their behavior and habits, here, taking the Sikhism as example, we will have a better understanding of Jess’s family, Sikhs, followers of the Sikh religion, centered in Punjab State, in northwestern India.Sikhism is an ethical monotheism fusing elements of Hinduism and Islam. It was founded around 1950s, In Jess’s family's living room is a large portrait of a Sikh spiritual leader, called Nanak, but above Jess's bed is her own inspiration–the British soccer superstar David Beckham, and there is a distinctive contrast between Indian traditional belief and modern British cultural shock.According this story, it’s not difficult to get conclusion that it is incredible for Indian people to get married with a pagan or people without same belief, but, in Bri tish, Christianity is the dominant world view. In this land, it is not a easy job to infuse with the native Indian Sikh religion, and vice versa. Conclusion England is the birthplace of modern football game, English people’s enthusiasm to football caused football culture’s coming into being, which exactly stands for the national culture. While India is a country of dances and songs.The scene of Indian jolly wedding with dance and song in this movie is just the epitome of Indian culture. Young people always can accept new things easily, in this movie; it is the two girls who play the role of fusion of two cultures. There indeed are some cultural shocks during people’s communication around the world, no matter which aspect it is, religion, ethnic, family or something else. Now that we live in the same earth, it is very important for people of different cultures to understand and respect each other.Thus, a peaceful and harmonious world would be around us!

Action And Necessity For All Human Beings Marketing Essay CHAPTER 1 Eating is observably a daily action and necessity for all human beings. Depending on individual’s reason for eating at restaurants, individual intentionally or instinctively assess a multifarious set of attributes ahead of choosing a restaurant. The significance involved to these restaurant attributes is ultimately evaluated in the customer’s mind, leading to a decision of purchasing. Some factors, like age, company and even social division come into take part in to amplify these attributes as the customer makes a decision of dining (Johnson and Champaner, 2004). The restaurant industry has undoubtedly not been free from either augmented competition or from increasing customer expectations regarding quality. In the greatly competitive food industry, large operators chain have a propensity to gain competitive gain in the course of cost leadership, likely only due to standardization and economies of scale beginning from large market shares, while smaller, indep endent restaurants on the other hand endeavor to gain benefit through differentiation (Lowenstein, 1995). Branding keeps on gaining importance in the marketing of restaurants services and marketers have spent lot of money to create and give support to brand images.

Reason and Faith Essay Example | Topics and Well Written Essays - 1500 words

Reason and Faith - Essay Example Faith is the opposite of reason, and it does not require any evidence for an individual to believe in a given issue or authority. On this basis, faith is a demonstration of assent or trust (Albl, 22). Faith, therefore, involves an act of commitment that emanates from the believer, in relation to a given belief. Religious faith involves the belief of an individual to a supernatural deity or God. The root cause of this faith always comes from an individual revelation of God, or the workings of God (The Bible, 3). On this note, revelation can either be direct, personally experiencing the powers of God. It can also be indirect, that is experiencing the powers of God through the testimonies of other people. Faith that emanates from religion is of two types, namely evidence insensitive faith, and evidence sensitive faith. Evidence sensitive faith is built upon by demonstrable truths, which includes testimonies brought forth by believers or people who ascribe to the same Faith. Mueller (27) denotes that this type of faith is also built on the teachings and lives of people who believed in God. On the other hand, Mueller (29) denotes that evidence-insensitive faith is built upon the individual experiences of a person with his God. All (26) explains that it is possible for a person to believe in God, through faith, or through reason. This paper takes a stand that the Bible is the main book that provides guidance on an individual’s Christian faith. The reason is only used to confirm and provide support for the various religious beliefs. Prickett and Robert (36) denote that the main factor that led to the problems associated with reason and faith comes from the concept of revelation. All religious beliefs are based on revelations. Revelations always entail an individual’s experiences with God, which in turn they are described through sacred pronunciations (Prickett and Robert, 33).  Ã‚  

English-Language Learners Essay Example | Topics and Well Written Essays - 1000 words

English-Language Learners - Essay Example Advantages Some of the most considerable benefits include better understanding of course material, better communication with teachers, and better exam performance. 1. Better Understanding of Course Primary language teaching helps both teachers and students. Teachers are able to transfer knowledge to their students easily. It is also easy for the students to understand the concepts in their native languages because of their familiarity with those languages. 2. Better Communication with Teachers Primary language also helps teachers and students properly communicate with each other. Students can ask questions to their teachers in their native languages, which is not easy if the communication language is other than their native languages. Moreover, students can also share their ideas more effectively with their teachers. 3. Better Exam Performance Improved exam performance is another advantage of teaching students in their primary languages. Students properly understand the concepts in t heir primary languages. As a result, they are able to deliver good results. Students are able to write what come in their minds. They do not have to translate their thoughts in order to write them on paper. Disadvantages Teaching in primary languages also has a couple of disadvantages. Those disadvantages include poor grades in international exams and decreased job opportunities. 1. Poor Grades in International Exams Those students, who get education in their native languages, find it difficult to show good performances in international exams because the testing language for most of the international exams is English. Students having less knowledge of English language cannot understand the exam questions properly which results in poor exam performance. 2. Decreased Job Opportunities Today, most of the companies prefer to hire such individuals who are proficient in speaking English language. Those students, who have less understanding of English, are unable to get high paying jobs. T hus, the number of job opportunities decrease for such students, which is a major disadvantage of being less proficient in speaking English. English Language Instruction I personally believe that English language instruction should replace native language instruction. The reason is that English has become a global language. â€Å"English language, as of today, has come to be known as the global language of the world† (Bahadur, 2012). If we analyze different languages that people speak in different parts of the world, we come to know that English is the language, which has the highest speaking rate. Yorke (2007) states, â€Å"English is a global language that allows many diverse peoples around the world to communicate when they don't speak, read, write, or understand one another's language†. People belonging to different parts of the world not only understand English language but also they can speak it well. English language has been included in many of the bilingual pr ograms, which validates its importance as a major instruction language (Marlowe & Canestrari, 2006, p. 154). The reason is that English is a language, which people use for medical, business, and scientific communication all over the world. Many scholars and researchers prefer to do their scientific and medical researches in English because of its high understandability and speaking rate. Countries can progress only if their citizens get high quality education from the best universities of the world. Today, the United States of

Stem cell research Paper Example | Topics and Well Written Essays - 2500 words - 1

Stem cell - Research Paper Example Although no person can forecast the outcomes from fundamental research completed during the past generation, there is sufficient existing information to suggest that a great deal of this enthusiasm is warranted. This passion and interest is not shared by persons of the religious conservative faction who was instrumental in slowing stem cell research in the U.S. during the previous presidential administration. This group is against embryonic stem cell research which they allege is immoral and describe as devaluing human life, in much the same way as legal abortion do, drawing a connection between the two controversial subjects. This dialogue will provide a summary of stem cell research and its benefits to humanity, the debate involving the matter and the arguments for continued studies. Definition of Stem Cells Stem cells are essentially the building block cells of a living being and in humans are capable of becoming more than 200 different kinds of tissue. â€Å"Stem cells have trad itionally been defined as not fully differentiated yet to be any particular type of cell or tissue† (Irving, 1999). Adult stem cells are located in small numbers within most tissues, but the preponderance of stem cells can be acquired from the umbilical cord. A more accurate term is â€Å"somatic stem cells† (Sullivan, 2004). ... A good example (of adult stem cells) is blood, but this is true for muscle and other connective tissue as well, and may be true for at least some nervous system cells† (Chapman et al, 1999). Consensus of Studies Much research has been performed by scientists in an effort to establish whether adult tissue stem cells have comparable developmental possibilities as the embryonic stem cells. Scientists now agree that this research has conclusively demonstrated that adult stem cells are not as feasible as embryonic stem cells. Embryonic stem cells possess a far superior potential and effectiveness because, contrasting adult stem cells, they have the capability to develop into virtually all cells present in the human body. Adult stem cells merely have the capacity to develop into a small number of cell types. Additionally, embryonic stem cells divide perpetually but adult stem cells do not which diminish their capability of developing into new kinds of cells.   Stem cells are of ext ensive interest for science and medicine, because they boast the potential, under appropriate conditions, to develop into nearly all of the cell types. Goals of research The three main goals for doing stem cell research are acquiring essential scientific information regarding embryonic development; treating incapacitating disorders such as Alzheimer’s or Parkinson’s and for testing new medications rather than having to use animals (Irving, 1999). Stem cell research is also likely to help victims of diabetes, bone diseases, spinal cord injuries and stroke. The scientific techniques for acquiring stem cells could be the forerunner to unparalleled advances and possibly cures for these and other maladies. It has been

NURSING CAPSTONE PRACTICUM Research Paper Example | Topics and Well Written Essays - 500 words

NURSING CAPSTONE PRACTICUM - Research Paper Example Although it is thought that reviewing the material and learning how to answer computer-generated questions are the optimal preparation methods for the NCLEX-RN examination, strategies that build self-confidence, knowledge, and the professionalism of the nurse are equally important (Hermann & Johnson, 2009). There are several different types of testing styles, and each student will be comfortable with a different type of examination style, depending on which portion of the cerebrum they are most comfortable using; those who are most comfortable with the left frontal lobe prefer oral presentations, abstract questions, summarization, essay questions, investigative writing, and multiple choice questions. Students who are predominant in their right frontal lobe prefer computerized essay questions, project submissions, and composition questions. Those whose principal lobe is the left posterior lobe are best with matching questions, true or false questions, and precise memorization, while t hose whose principal lobe is the right posterior are uncomfortable with any form of exam, prefer practical questions, and feel a compulsion to engage in conversation around the examinations (Taylor, 2012); once the student is familiar with what category they fall into, they can work to adapt to that style, and overcome the difficulties that may be presented due to the type of testing style used on the NCLEX-RN examination. Most students will explore a number of NCLEX preparation resources in addition to taking an extensive NCLEX preparation or review course prior to taking the examination; they will also most likely access an NCLEX Self-Assessment module (University of Washington, 2013) , such as the one found at Test Prep Review (Test Prep Review, 2013). Key aspects in making sure that the student passes the NCLEX-RN examination include

Scholarly Person in the US Government past or present Term Paper

Scholarly Person in the US Government past or present - Term Paper Example As a Missionary Alexander Crummell was an ordained missionary in Liberia (1853 – 1872) belonging to the Episcopal Church. His eventful life as a missionary spanned over twenty years there, once again he faced discrimination because of his race and background. His primary aim as a Christian minister was to ‘civilize’ the African race by encouraging them to embrace Christianity and replace their native customs, beliefs and religious practices they followed. Keeping this in mind Alexander Crummell founded the church and a school in Washington DC in a bid to bring about a revolutionary change among the African people. As a Religious Leader Alexander Crummell’s tryst with Africa had many dimensions to it. He believed that every race on the Earth had a purpose and so did the African race too. Crummell had unshakable belief of the divine purpose of the African race. His key concern was man’s march to perfection through civilization. ... His aim was to initiate the African people towards civilization by removing the scales of ignorance from their eyes and bringing them into the light of religious enlightenment. However, Crummell’s hopes and dreams for the Negro race were never reconciled or satisfied with his philosophy of ‘civilizationism’. As a Black Nationalist He is considered to be one of the most authoritative figures as far as Black Nationalism is concerned. Being a religious minister of the Episcopal Church he very strongly detested and protested against the ignorant subjugation of the Negro’s against their white counterparts and struggled hard to bring about a Black nationalistic change in the belief and attitudes of the Africans. Crummell’s common lament was â€Å"What the Negro needs is Civilization.† By civilization he did not mean the literal term of the word but a clear mind which is free from false heathen thoughts and beliefs. Civilization to him also meant per sonal responsibility, family development and social obligation to society. Crummell’s religious and puritanical ideologies of the human race and in particular for the Africans, served to pave the path for reshaping and reinventing of European racial theories creating a huge impact on great thinkers of his day. Though Crummellian philosophy is looked upon by many scholars as an antecedent, yet it is highly criticized from many angles. The chief reason being that Crummell lived in a very different time period when compared to the scholars of today. His Political Ideologies Even though Crummell claimed that he was not interested in politics and had no political ambitions whatsoever, yet, it is evident that he hoped to influence society by making use of his intellectualism

The Surrealism of Salvador Dali Essay Example | Topics and Well Written Essays - 2500 words

The Surrealism of Salvador Dali - Essay Example The essay "The Surrealism of Salvador Dali" focuses on the surrealistic art of Salvador Dali. Surrealism was born in the period between World War I and World War II, 1919-1939. When we look at Dal’s work during this period, we can see the beginning of a thoughtful contemplation on surrealism. One of the most convenient places to readily access Dali’s body of work is the online site called Virtual Dali. At this web site one can access the works through the organized periods of the artist’s work: 1910-1927; 1951-1959; 1960-1972; 1972-1983. So when we say that the period to 1919-1939 reflected a thoughtfulness on the subject of surrealism, it was perhaps because many of the works from that period are portraiture that appears caught between cubism – introduced by Pablo Picaso between 1907-1914 - and surrealism, although some of the themes that we see in works like Saltimbanques has some of the recurring elements that we find in later Dali surrealism. In Saltim banques we see familiar figures from later works in familiar poses, but not in the state of surrounding surrealism. Still, it was clear that surrealism was on Dali’s mind, and if a community was represented by surrealism, a philosophy, then these early works demonstrates that Salvador Dali was leaning towards the surrealist community, exploring his own like-mindedness with the community. Pierrot Playing the Guitar is almost as if the artist is still mired in the muck between cubism and what would become his own specialty in surrealism.

The Love Song of J. Alfred Prufrock by T. S. Eliot Essay Example for Free

The Love Song of J. Alfred Prufrock by T. S. Eliot Essay The Love Song of J. Alfred Prufrock (or simply Prufrock) is T. S. Eliot’s most popular poem and it is the one responsible for the launch of his career as one of the 20th century’ leading and influential poet. The poem takes the form of a dramatic monologue and it is considered as one of the most anthologized poem in the 20th century.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Prufrock is a poem which made use of lots of literary devices such as similes, personifications, repetitions, allusions, imageries and the like, all of which contributed a great deal to the tone of the poem which is miserable and unhappy, it also helped contribute to the theme of indecision (which led to lots of missed opportunities), sexuality, and paralysis. For one the use of simile is clear in the following line, â€Å"when the evening is spread out against the sky like a patient etherized upon a table† (Eliot, 1917) and it skillfully illustrates the solemn outdoor setting in contrast to the party setting which would later on take place in the poem.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Repetition is one of the most essential tools used by Eliot in the poem. For one, in the following stanza â€Å"In the room women come and go talking of Michaelangelo† (Eliot, 1917), Eliot brings the audience to the place Prufrock himself finds himself tied into, and this particular repetition contributed a lot in setting the tone of the poem as it shows the readers how Prufrock muses on how he wants to tell a woman how he truly feels and yet for some melancholic reason, he cannot.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Upon reading the poem one could envision that Prufrock is not really that old, he is probably a middle-aged man who is trying to examine what went wrong with his life, or trying to look back to the choices he made at the course of his life. Among the things he constantly look upon is the things he did not do, his regrets for acting the way he did, for his indecisions, and most of all he is looking back on his failure with regards to women thus one could then on say that one of the primary tones of the poem is that of a tired, ironic self-criticism. The character of Prufrock made many references on his going bald, most notably was a scene with a reaper who is holding his coat for him so that he could then on leave this material world. Prufrock tried to make himself feel what it is like to be young again one notable example was when he tried to dress and fashion his hair the way young men does. However, in spite of this particular endeavor he knows deep inside that it is no use since he would no longer be young again and this particular fear of approaching old age contributed a great deal to his paralysis which is the primary theme of this poem.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   From the title of the poem alone one could have an idea that Prufrock is no ordinary or traditional love poem. Prufrock then is a ludicrous name and the author wants the subconscious implication of a prude in a frock. The original title of the poem is actually Prufrock Among Women and this particular emasculation added a certain depth to the themes the author would delve into which rotates around the notion of paralysis and heroism. As was mentioned earlier this poem takes the form of a dramatic monologue in which the speaker unconsciously reveals a part of himself to the silent readers. The poem shows a great deal of Prufrock’s inability to commit and express himself to women or to love, or to other individuals for that matter.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The 2st stanza of the poem hints that Profruck and a companion are out for an evening walk. Most of the themes and tone of Profruck illustrates profound melancholy and lack of communication or inability to express himself. The city discussed in the poem appears gloomy, it seems to portray the city in a half dead, desolate, and lonely feel. The streets seems to curve to a particular conclusion or question and it seems to ask if the protagonist should dare to assert himself or to reach out and try to communicate with other people.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The fourth stanza of the poem implies to life’s triviality as could be seen on the following line â€Å"hundred indecisions†¦before the taking of toast and tea†. The readers could then envision Prufrock worrying himself over life’s trivialities such as what tie to wear at the party and what words he should use to strike up a conversation (presumably with a woman) at the party. The women the protagonist is about to meet at the party are belittled in that their primary use is to serve as some kind of a decoration and keep shallow conversation going all throughout the party as could be seen on the following line â€Å"that lift and drop a question on your plate† (Eliot, 1917).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In the sixth stanza of the poem one could envision the protagonist hesitating on whether he should continue to climb the stairs which would take him to the place where the party is being held, he keep on worrying on whether he should â€Å"dare† communicate or try to reach out to these people. In the seventh stanza the protagonist was pondering about the things he did or the trivialities he did in his life and it also shows that he knows what kinds of people would be present at the party. He knows that those people are full of life’s superficiality. These particular people were further singled out in the 9th stanza as women of women on which the protagonist seems to posit an attitude synonymous to sour-graping.   Upon close observation the readers would then on see that these elegant women have hairy arms, however, in spite of that these women still have some kind of an effect to the protagonist of the poem as could be seen when he was not able to organize his thoughts which is being diverted by the smell of the perfume of these women. It is important in this line to notice that Prufrock does not treat these women as a whole people but rather merely as part of their physicalities which attracts and mislead other people as could be seen on the following lines, â€Å"eyes that fix you in a formulated phrase†, â€Å"faces that you meet†, voices dying with a dying fall† (Eliot, 1917) and the like.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   On stanzas 79-80 the protagonist was once again pondering on whether given lots of empty times should he try to assert his personality and try to reach out to other individuals. Mainly because the protagonist talked a great deal about women on his earlier stanzas one could then assume that the line â€Å"force the moment to its crisis† (Eliot, 1917) have an innuendo of sexuality because whereas the inability to communicate himself appears to be the primary theme of the poem, the protagonist incapacity to have sexual relationship is taken care of in a more specific manner. If someone is incapable of having sexual relationship with another individual, he is cut off from the some things considered worth while in life and the protagonist is portrayed as someone who is incapable of making a move on a woman (he could not even reach out to converse to any people, much less a woman) because of his fear to look ludicrous in front of them.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The protagonist inability to make use of the time or opportunities given him is signified by the past tense found in the twelfth stanza. In this stanza the readers would be able to see that if the protagonist indeed tries to reach out to people particularly to the woman he likes he would only appear preposterous and these people would not even be able to understand him. In stanzas 95-97 the protagonist made an implication that he ever approach or make any kind of insinuation to a woman â€Å"roll†¦strength and all..sweetness up into one ball, and tearing†¦pleasures with rough strife † (Eliot, 1917) there is a huge chance that he would be misunderstood and worst they would be disgusted with him and put him off. All of these reasons among many others seem to answer the earlier question on whether he should dare to assert himself. The protagonist states â€Å"No!† because he sees himself as insignificant, he is so full of self-consciousness and because of that he is unworthy of â€Å"disturb(ing) the universe† (Eliot, 1917).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Now that the fundamental question of him asserting himself has finally been answered the protagonist is once again seen to be looking at what his life would be like (he would grow old and bald) and he would also wonder if he has the guts to eat a peach â€Å"do I dare to eat a peach† (Eliot, 1917). This particular line could be viewed in different manners one of which is that fresh fruit because of digestive problems however, the peach could also be seen to have an underlying sexual connotation. Fruits in general have a sexual connotation as the ripened ovary of a plant and peach in particular holds more sexual connotation because of its flesh like color, its soft texture and its downiness. The peach’s shape and texture symbolizes the female genitalia thus one could see in the line mentioned above that the protagonist is wondering that if he is unable to sexually assert himself to a woman while he was still in the prime of his life, how else would he be able to sexually assert himself when he becomes an old man. Peach also have other meanings. Peach is the Chinese symbol for marriage and immortality, both of which the protagonist so want to have in his life. As could be seen then, the protagonist pondering on whether he would dare eat a peach has got something to do with his sexual ineptness. As the poem ends, the protagonist was imagining mermaids, oe men’s ideal dream of women sitting on the beach, however, in spite of the fact that it only happened on his imagination, the mermaids still did not sing for him. When the protagonist was awakened from his dream by a human voice one could then conclude that even in dreams, the protagonist is still paralyzed and non-active. This particular paralysis, the protagonist’s inability to act and to grab at the opportunities given to him by life is the primary theme ever present in The Love Song of J. Alfred Prufrock.

Types Of Pollution And Their Causes Environmental Sciences Essay

Types Of Pollution And Their Causes Environmental Sciences Essay Pollution  is the introduction of contaminants into a natural environment that causes discomfort to the  ecosystem  i.e. physical systems or living organisms.  Pollution can take the form of  chemical substances  or  energy, such as noise, heat, or light. Pollutants, the elements of pollution, can be foreign substances or energies, or naturally occurring; when naturally occurring, they are considered contaminants when they exceed natural levels. Pollution is often classed as  point source  or  nonpoint source pollution. POINT SOURCE POLLUTION A  point source of pollution  is a single identifiable  localized  source of  air,  water,  thermal,  noise  or  light  pollution. A  point source  has negligible extent, distinguishing it from other pollution source geometries. The sources are called  point sources  because in mathematical modeling, they can be approximated as a mathematical  point  to simplify analysis. Pollution point sources are identical to other  physics,  engineering,  optics  andchemistry  point sources except that their emissions have been labeled Water pollution from an  oil refinery  wastewater  discharge outlet Noise pollution from a  jet engine Disruptive  seismic  vibration from a localized seismic study Light pollution from an intrusive  street light Thermal pollution from an industrial process  outfall Radio  emissions from an interference-producing electrical device Types of air pollution sources which have finite extent are  line sources,  area sources  and  volume sources. Air pollution sources are also often categorized as either stationary or mobile. NON POINT SOURCE POLLUTION Non-point source (NPS) pollution  is  water pollution  affecting a water body from diffuse sources, such as polluted  runoff  from  agricultural  areas draining into a river, or wind-borne debris blowing out to sea. Nonpoint source pollution can be contrasted with  point source  pollution, where discharges occur to a body of water at a single location, such as discharges from a chemical factory,  urban runoff  from a roadway  storm drain, or from ships at sea. NPS may derive from many different sources with no specific solution to rectify the problem, making it difficult to regulate. It is the leading cause of water pollution in the  United States  today, with polluted runoff from agriculture the primary cause. Other significant sources of runoff include  hydrological  and  habitat modification, and  silviculture  (forestry). Contaminated stormwater washed off of  parking lots,  roads  and  highways, and  lawns  (often containing  fertilizers  and  pesticides) is called  urban runoff. This runoff is often classified as a type of NPS pollution. Some people may also consider it a point source because many times it is channeled into municipal storm drain systems and discharged through pipes to nearby  surface waters. However, not all urban runoff flows through storm drain systems before entering waterbodies. Some may flow directly into waterbodies, especially in developing and suburban areas. Also, unlike other types of point sources, such as industrial discharge, wastewater plants and other operations, pollution in urban runoff cannot be attributed to one activity or even group of activities. Therefore, because it is not caused by an easily identified and regulated activity, urban runoff pollution sources are also often treated as true nonpoint sources as municipalities work to abate t hem. MAJOR FORMS OF POLLUTION ::: The major forms of pollution are listed below along with the particular pollutants relevant to each of them: AIR POLLUTION Air pollution  is the introduction of  chemicals,  particulate matter, or  biological materials  that cause harm or discomfort to humans or other living organisms, or damages the  natural environment  into the atmosphere. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet  Earth.  Stratospheric  ozone depletion  due to air pollution has long been recognized as a threat to human health as well as to the Earths  ecosystems. NOISE POLLUTION Noise pollution  (or  environmental  noise) is displeasing human, animal or machine-created sound that disrupts the activity or balance of human or animal life. The word  noise  comes from the Latin word  nauseas, meaning seasickness. The source of most outdoor noise worldwide is mainly  construction  and  transpHYPERLINK http://en.wikipedia.org/wiki/Transportortation systems, including  motor vehicle  noise,  aircraft noise  and  rail noise.  Poor  urban planning  may give rise to noise pollution, since side-by-side industrial and residential buildings can result in noise pollution in the residential area. Indoor and outdoor noise pollution sources include  car alarms, emergency service  sirens, mechanical equipment,  fireworks, compressed  air horns, groundskeeping equipment, barking dogs, appliances,lighting  hum, audio entertainment systems, electric  megaphones, and loud people. SOIL CONTAMINATION Soil contamination  (soil pollution) is caused by the presence of  xenobiotic  (human-made) chemicals or other alteration in the natural soil environment. This type of contamination typically arises from the rupture of  underground storage tanks, application of  pesticides, percolation of contaminated surface water to subsurface strata, oil and fuel dumping, leaching of wastes fromlandfills  or direct discharge of industrial wastes to the soil. The most common chemicals involved are petroleum  hydrocarbons,  solvents, pesticides, lead and other  heavy metals. This occurrence of this phenomenon is correlated with the degree of industrialization and intensities of chemical usage. The concern over soil contamination stems primarily from health risks, from direct contact with the contaminated soil, vapors from the contaminants, and from secondary contamination of water supplies within and underlying the soil. Mapping of contaminated soil sites and the resulting cleanup are time consuming and expensive tasks, requiring extensive amounts of  geology,hydrology,  chemistry  and  computer modeling  skills. It is in  North America  and  Western Europe  that the extent of contaminated land is most well known, with many of countries in these areas having a legal framework to identify and deal with this environmental problem; this however may well be just the tip of the iceberg with developing countries very likely to be the next generation of new soil contamination cases. RADIOACTIVE CONTAMINATION Radioactive contamination, also called  radiological contamination, is radioactive substances on surfaces, or within solids, liquids or gases (including the human body), where their presence is unintended or undesirable, or the process giving rise to their presence in such places. Also used less formally to refer to a quantity, namely the  activity  on a surface (or on a unit area of a surface). Contamination does not include residual  radioactive material  remaining at a site after the completion of  decommissioning. The term radioactive contamination may have a connotation that is not intended. The term radioactive contamination refers only to the presence of  radioactivity, and gives no indication of the magnitude of the hazard involved. Radioactive contamination is typically the result of a spill or accident during the production or use of  radionuclides  (radioisotopes), an unstable nucleus which has excessive energy. Contamination may occur from radioactive gases, liquids or particles. For example, if a radionuclide used in  nuclear medicine  is accidentally spilled, the material could be spread by people as they walk around. Radioactive contamination may also be an inevitable result of certain processes, such as the release of radioactive  xenon  in  nuclear fuel reprocessing. In cases that radioactive material cannot be contained, it may be diluted to safe concentrations.  Nuclear fallout  is the distribution of radioactive contamination by a  nuclear explosion. THERMAL POLLUTION   Thermal pollution  is the degradation of  water quality  by any process that changes ambient water  temperature. A common cause of thermal pollution is the use of water as a  coolant  by  power plants  and industrial manufacturers. When water used as a coolant is returned to the natural environment at a higher temperature, the change in temperature (a) decreases  oxygen  supply, and (b) affects  ecosystem  composition.  Urban runoffstormwater  discharged to surface waters from  roads  and  parking lotscan also be a source of elevated water temperatures. When a power plant first opens or shuts down for repair or other causes, fish and other organisms adapted to particular temperature range can be killed by the abrupt rise in water temperature known as thermal shock. SOURCES AND CAUSES Air pollution comes from both natural and man made sources. Though globally man made pollutants from combustion, construction, mining, agriculture and warfare are increasingly significant in the air pollution equation. Motor vehicle emissions are one of the leading causes of air pollution.  China,  United States,  Russia,  Mexico, and  Japan  are the world leaders in air pollution emissions. Principal stationary pollution sources include  chemical plants, coal-fired  power plants,  oil refineries,  petrochemical  plants,  nuclear waste  disposal activity, incinerators, large livestock farms (dairy cows, pigs, poultry, etc.),  PVC  factories, metals production factories, plastics factories, and other heavy industry. Agricultural air pollution comes from contemporary practices which include clear felling and burning of natural vegetation as well as spraying of pesticides and herbicides About 400 million metric tons of  hazardous wastes  are generated each year.  The  United States  alone produces about 250 million metric tons.  Americans constitute less than 5% of the  worldHYPERLINK http://en.wikipedia.org/wiki/Worlds_populationHYPERLINK http://en.wikipedia.org/wiki/Worlds_populations population, but produce roughly 25% of the worlds  COHYPERLINK http://en.wikipedia.org/wiki/Carbon_dioxide2,  and generate approximately 30% of  worlds waste.  In 2007,  China  has overtaken the United States as the worlds biggest producer of CO2. In February 2007, a report by the Intergovernmental Panel on Climate Change (IPCC), representing the work of 2,500 scientists from more than 130 countries, said that humans have been the primary cause of global warming since 1950. Humans have ways to cut greenhouse gas emissions and avoid the consequences of global warming, a major climate report concluded. But in order to change the climate, the transition from fossil fuels like coal and oil needs to occur within decades, according to the final report this year from the UNs Intergovernmental Panel on Climate Change (IPCC). Some of the more common  soil  contaminants are  chlorinated hydrocarbons  (CFH),  heavy metals  (such as  chromium,  cadmiumfound in rechargeable  batteries, and  leadfound in lead  paint,  aviation fuel  and still in some countries,  gasoline),  MTBE,zinc,  arsenic  and  benzene. In 2001 a series of press reports culminating in a book called  Fateful Harvest  unveiled a widespread practice of recycling industrial byproducts into fertilizer, resulting in the contamination of the soil with various metals. Ordinary municipal  landfills  are the source of many chemical substances entering the soil environment (and often groundwater), emanating from the wide variety of refuse accepted, especially substances illegally discarded there, or from pre-1970 landfills that may have been subject to little control in the U.S. or EU. There have also been some unusual releases of  polychlorinated dibenzodioxins, commonly called  dioxins  for simplic ity, such as  TCDD. Pollution can also be the consequence of a natural disaster. For example,  hurricanes  often involve water contamination from sewage, and  petrochemical  spills from ruptured  boats  or  automobiles. Larger scale and environmental damage is not uncommon when coastal  oil rigs  or  refineries  are involved. Some sources of pollution, such as  nuclear power  plants or  oil tankers, can produce widespread and potentially hazardous releases when accidents occur. In the case of  noise pollution  the dominant source class is the  motor vehicle, producing about ninety percent of all unwanted noise worldwide. EFFECTS HUMAN HEALTH Adverse  air quality  can kill many organisms including humans. Ozone pollution can cause  respiratory disease,  cardiovascular disease,  throat  inflammation, chest pain, andcongestion. Water pollution causes approximately 14,000 deaths per day, mostly due to contamination of  drinking water  by untreated  sewage  in  developing countries. An estimated 700 million  Indians  have no access to a proper toilet, and 1,000 Indian children die of diarrhoeal sickness every day.  Nearly 500 million Chinese lack access to safe drinking water.  656,000 people die prematurely each year in  China  because of air pollution. In  India, air pollution is believed to cause 527,700 fatalities a year.  Studies have estimated that the number of people killed annually in the US could be over 50,000. Oil spills can cause  skin  irritations and  rashes. Noise pollution induces  hearing loss,  high blood pressure,  stress, and  sleep disturbance.  Mercury  has been linked to  developmental deficits  in children and  neurologic  symptoms. Older people are majorly exposed to diseases induced by air pollution. Those with heart or lung disorders are under additional risk. Children and infants are also at serious risk.  Lead  and other  heavy metals  have been shown to cause neurological problems. Chemical and  radioactive  substances can  cause  cancerand  as well as  birth defects. ENVIRONMENT Pollution has been found to be present widely in the  environment. There are a number of effects of this: Biomagnification  describes situations where toxins (such as  heavy metals) may pass through  trophic levels, becoming exponentially more concentrated in the process. Carbon dioxide  emissions cause  ocean acidification, the ongoing decrease in the pH of the Earths oceans as CO2  becomes dissolved. The emission of  greenhouse gases  leads to  global warming  which affects ecosystems in many ways. Invasive species  can out compete native species and reduce  biodiversity. Invasive plants can contribute debris and biomolecules (allelopathy) that can alter soil and chemical compositions of an environment, often reducing native species  competitiveness. Nitrogen oxides  are removed from the air by rain and  fertilise  land which can change the species composition of ecosystems. Smog  and haze can reduce the amount of sunlight received by plants to carry out  photosynthesis  and leads to the production of  tropospheric ozone  which damages plants. Soil can become infertile and unsuitable for plants. This will affect other  organisms  in the  food web. Sulphur dioxide  and  nitrogen oxides  can cause  acid rain  which lowers the  pH  value of soil. POLLUTION CONTROL :: Pollution control is a term used in  environmental management. It means the control of  emissions  and  effluents  into air, water or soil. Without pollution control, the waste products from consumption, heating, agriculture, mining, manufacturing, transportation and other human activities, whether they accumulate or disperse, will degrade the  environment. In the hierarchy of controls,  pollution prevention  and  waste minimization  are more desirable than pollution control. PRACTICES:: RECYCLING :::: Recycling  involves processing used  materials  (waste) into new products to prevent waste of potentially useful materials, reduce the consumption of fresh raw materials, reduce  energy  usage, reduce air pollution (from  incineration) and water pollution (from  landfilling) by reducing the need for conventional waste disposal, and lower  greenhouse gas  emissions as compared to virgin production.  Recycling is a key component of modern waste reduction and is the third component of the Reduce,  Reuse, Recycle  waste hierarchy. Recyclable materials include many kinds of  glass,  paper,  metal,  plastic,  textiles, and  electronics. Although similar in effect, the  composting  or other reuse of  biodegradable waste   such as  food  or  garden waste   is not typically considered recycling.  Materials to be recycled are either brought to a collection center or picked up from the curbside, then sorted, cleaned, and reprocessed into new materials bound for manufacturing. In a strict sense, recycling of a material would produce a fresh supply of the same material-for example, used office  paper  would be converted into new office paper, or used  foamed polystyrene  into new polystyrene. However, this is often difficult or too expensive (compared with producing the same product from raw materials or other sources), so recycling of many products or materials involves their  reuse  in producing different materials (e.g.,  paperboard) instead. Another form of recycling is the  salvage  of certain materials from complex products, either due to their intrinsic value (e.g.,  lead  from  car batteries, or  goldfrom  computer  components), or due to their hazardous nature (e.g., removal and reuse of  mercury  from various items). Critics dispute the net economic and environmental benefits of recycling over its costs, and suggest that proponents of recycling often make matters worse and suffer from  confirmation bias. Specifi cally, critics argue that the costs and energy used in collection and transportation detract from (and outweigh) the costs and energy saved in the production process; also that the jobs produced by the recycling industry can be a poor trade for the jobs lost in logging, mining, and other industries associated with virgin production; and that materials such as paper pulp can only be recycled a few times before material degradation prevents further recycling. Proponents of recycling dispute each of these claims, and the validity of arguments from both sides has led to enduring controversy. PROCESS OF RECYCLING Collection A number of different systems have been implemented to collect recyclates from the general waste stream. These systems lie along the spectrum of trade-off between public convenience and government ease and expense. The three main categories of collection are drop-off centres, buy-back centres and curbside collection. Drop-off centres require the waste producer to carry the recyclates to a central location, either an installed or mobile collection station or the reprocessing plant itself. They are the easiest type of collection to establish, but suffer from low and unpredictable throughput. Buy-back centres differ in that the cleaned recyclates are purchased, thus providing a clear incentive for use and creating a stable supply. The post-processed material can then be sold on, hopefully creating a profit. Unfortunately government subsidies are necessary to make buy-back centres a viable enterprise, as according to the United States Nation Solid Wastes Management Association it costs on average US$50 to process a ton of material, which can only be resold for US$30. CURBSIDE COLLECTION Curbside collection encompasses many subtly different systems, which differ mostly on where in the process the recyclates are sorted and cleaned. The main categories are mixed waste collection, commingled recyclables and source separation.  A  waste collection vehicle  generally picks up the waste. At one end of the spectrum is mixed waste collection, in which all recyclates are collected mixed in with the rest of the waste, and the desired material is then sorted out and cleaned at a central sorting facility. This results in a large amount of recyclable waste, paper especially, being too soiled to reprocess, but has advantages as well: the city need not pay for a separate collection of recyclates and no public education is needed. Any changes to which materials are recyclable is easy to accommodate as all sorting happens in a central location. In a Commingled or  single-stream system, all recyclables for collection are mixed but kept separate from other waste. This greatly reduces the need for post-collection cleaning but does require  public education  on what materials are recyclable. Source separation is the other extreme, where each material is cleaned and sorted prior to collection. This method requires the least post-collection sorting and produces the purest recyclates, but incurs additional  operating costs  for collection of each separate material. An extensive public education program is also required, which must be successful if recyclate contamination is to be avoided. Source separation used to be the preferred method due to the high sorting costs incurred by commingled collection. Advances in sorting technology (see  sorting  below), however, have lowered this overhead substantially-many areas which had developed source separation programs have since switched to comingled collection. Sorting Once commingled recyclates are collected and delivered to a  central collection facility, the different types of materials must be sorted. This is done in a series of stages, many of which involve automated processes such that a truck-load of material can be fully sorted in less than an hour.  Some plants can now sort the materials automatically, known as  single-stream recycling. A 30 percent increase in recycling rates has been seen in the areas where these plants exist. Initially, the commingled recyclates are removed from the collection vehicle and placed on a conveyor belt spread out in a single layer. Large pieces of  corrugated fiberboard  and  plastic bags  are removed by hand at this stage, as they can cause later machinery to jam. Next, automated machinery separates the recyclates by weight, splitting lighter paper and plastic from heavier glass and metal. Cardboard is removed from the mixed paper, and the most common types of plastic,  PET  (#1) and  HDPE  (#2), are collected. This separation is usually done by hand, but has become automated in some sorting centers: a  spectroscopic  scanner is used to differentiate between different types of paper and plastic based on the absorbed wavelengths, and subsequently divert each material into the proper collection channel.[4] Strong magnets are used to separate out  ferrous metals, such as  iron,  steel, and  tin-plated steel cans  (tin cans).  Non-ferrous metals  are ejected by  magnetic eddy currents  in which a rotating  magnetic field  induces  an electric current around the aluminium cans, which in turn creates a magnetic eddy current inside the cans. This magnetic eddy current is repulsed by a large magnetic field, and the cans are ejected from the rest of the recyclate stream.[4] Finally, glass must be sorted by hand based on its color: brown, amber, green or clear. GREEN HOUSE GASES AND GLOBAL WARNING Carbon dioxide, while vital for  photosynthesis, is sometimes referred to as pollution, because raised levels of the gas in the atmosphere are affecting the Earths climate. Disruption of the environment can also highlight the connection between areas of pollution that would normally be classified separately, such as those of water and air. Recent studies have investigated the potential for long-term rising levels of atmospheric carbon dioxide to cause slight but critical  increases in the acidity of ocean waters, and the possible effects of this on marine ecosystems. Global warming  is the increase in the  average temperature  of  Earths near-surface air and oceans since the mid-20th century and its projected continuation. According to the 2007  Fourth Assessment Report  by the  Intergovernmental Panel on Climate Change  (IPCC), global surface temperature increased 0.74  Ã‚ ±Ã‚  0.18  Ã‚ °C  (1.33  Ã‚ ±Ã‚  0.32  Ã‚ °F) during the 20th century. Global dimming, a result of increasing concentrations of atmospheric  aerosols  that block sunlight from reaching the surface, has partially countered the effects of warming induced by greenhouse gases. Climate model  projections summarized in the latest IPCC report indicate that the global  surface temperature  is likely to rise a further  1.1 to 6.4  Ã‚ °C  (2.0 to 11.5  Ã‚ °F)  during the 21st century.  The uncertainty in this estimate arises from the use of models with differing  sensitivity to greenhouse gas concentrations  and the use of differing  estimates of future greenhouse gas emissions. An increase in global temperature will cause  sea levels to rise  and will change the amount and pattern of  precipitation, probably including expansion of  subtropical  deserts.  Warming is expected to be  strongest in the Arcticand would be associated with continuing  retreat of glaciers,  permafrost  and  sea ice. Other likely effects include changes in the frequency and intensity of  extreme weather  events,  species extinctions, and changes in  agricultural yields. Warming and related changes will vary from region to region aroun d the globe, though the nature of these regional variations is uncertain.  As a result of contemporary increases in atmospheric carbon dioxide, the oceans have become  more acidic; a result that is predicted to continue. The  scientific consensus  is that  anthropogenic  global warming is occurring.  Nevertheless,  political  and  public debate  continues. The  Kyoto Protocol  is aimed at stabilizing greenhouse gas concentration to prevent a dangerous anthropogenic interference.  As of November 2009,  187 states had signed and ratified  the protocol. The  greenhouse effect  is the process by which  absorption  and  emission  of  infrared  radiation by gases in the  atmosphere  warm a  planets lower atmosphere and surface. It was proposed by  Joseph Fourierin 1824 and was first investigated quantitatively by  Svante Arrhenius  in 1896.  The question in terms of global warming is how the strength of the presumed greenhouse effect changes when human activity increases the concentrations of greenhouse gases in the atmosphere. Naturally occurring greenhouse gases have a mean warming effect of about 33  Ã‚ °C (59  Ã‚ °F).  The major greenhouse gases are  water vapor, which causes about 36-70 percent of the greenhouse effect;carbon dioxide  (CO2), which causes 9-26 percent;  methane  (CH4), which causes 4-9 percent; and  ozone  (O3), which causes 3-7 percent.  Clouds also affect the radiation balance, but they are composed of liquid water or ice and so have  different effects on radiation  from water vapor. Human activity since the  Industrial Revolution  has increased the amount of greenhouse gases in the atmosphere, leading to increased  radiative forcing  from CO2,  methane, tropospheric  ozone,  CFCs  andnitrous oxide. The  concentrations  of CO2  and methane have increased by 36% and 148% respectively since 1750.  These levels are much higher than at any time during the last 650,000 years, the period for which reliable data has been extracted from  ice cores.  Less direct geological evidence indicates that CO2  values higher than this were last seen about 20 million years ago.[41]  Fossil fuel  burning has produced about three-quarters of the increase in CO2  from human activity over the past 20 years. Most of the rest is due to land-use change, particularly  deforestation. Over the last three decades of the 20th century,  GDP  per capita  and  population growth  were the main drivers of increases in greenhouse gas emissions.  CO2  emissions are continuing to rise due to the burning of fossil fuels and land-use change.  Emissions scenarios, estimates of changes in future emission levels of greenhouse gases, have been projected that depend upon uncertain economic,sociological,  technological, and natural developments.  In most scenarios, emissions continue to rise over the century, while in a few, emissions are reduced.  These emission scenarios, combined with carbon cycle modelling, have been used to produce estimates of how atmospheric concentrations of greenhouse gases will change in the future. Using the six IPCC  SRES  marker scenarios, models suggest that by the year 2100, the atmospheric concentration of CO2  could range between 541 and 970 ppm.  This is an increase of 90-250% above the concentration in the year 1750. Fossil fuel reserves are sufficient to reach these levels and continue emissions past 2100 if  coal,  tar sands  or  methane clathrates  are extensively exploited. The destruction of  stratospheric  ozone by  chlorofluorocarbons  is sometimes mentioned in relation to global warming. Although there are a few  areas of linkage, the relationship between the two is not strong. Reduction of stratospheric ozone has a cooling influence.  Substantial ozone depletion did not occur until the late 1970s.  Ozone in the troposphere  (the lowest part of the  EarthHYPERLINK http://en.wikipedia.org/wiki/Atmosphere_of_EarthHYPERLINK http://en.wikipedia.org/wiki/Atmosphere_of_Earths atmosphere) does contribute to surface warming. 8 most polluted cities in India ::: Sukinda, Orissa Number of people affected:  2,600,000 Type of pollutant:  Hexavalent chromium and other metals   Source of pollution:  Chromite mines and processing Hexavalent chromium is: a nasty heavy metal used for stainless steel production and leather tanning that is carcinogenic if inhaled or ingested. In Sukinda, which contains one of the largest open cast chromite ore mines in the world, 60% of the drinking water contains hexavalent chromium at levels more than double international standards. An Indian health group estimated that 84.75% of deaths in the mining areas where regulations are nonexistent are due to chromite-related diseases. There has been virtually no attempt to clean up the contamination. Sukinda has been listed in the Top 10 most polluted places in the world by the US-based Blacksmith Institute. Labourers work at a road construction site near Vapi Vapi, Gujarat Number of people potentially affected:  71,000 Type of pollutant:  Chemicals and heavy metals Source of pollution:  Industrial estates If Indias environment is on the whole healthier than its giant neighbor Chinas, thats because India is developing much more slowly. But thats changing, starting in towns like Vapi, which sits at the southern end of a 400-km-long belt of industrial estates. For the citizens of Vapi, the cost of growth has been severe: levels of mercury in the citys groundwater are reportedly 96 times higher than WHO safety levels, and heavy metals are present in the air and the local produce. Its just a disaster, says Fuller. Vapi has been listed in the Top 10 most polluted places in the world by the US-based Blacksmith Institute. Mandi Gobindgarh, Punjab Number of people affected:  155,416 Type of pollutant:  High dust and smoke particulate Source of pollution:  Industrial units Gobindgarh in Punjab, also known as Loha mandi, recorded suspended particulate matter (microscopic particles in the air such as dust and smoke) level of 252 micrograms per cubic metre in 2007, 320 percent higher than the national standard level of 60 micrograms. Known for its iron and steel factories, it is one of the most polluted city in the country. The population in Gobindgarh shows a higher prevalence of symptoms of angina and cardiovascular disease. A ragpicker rows boat in polluted Gomti river in Lucknow Lucknow, UP Number of people affected:  30 lakh Type of pollutant:  High dust and smoke particulate Source of pollution:  Industrial units, vehicles Vehicular emissions are the main cause of air pollution in Lucknow.

Internet and Technology - Carnivore and the Publics Privacy Essay

Internet and Technology - Carnivore and the Public's Privacy Abstract: This paper discusses the potential for widespread invasion of the public's privacy on the Internet by the United States government. In particular, the paper will address the Carnivore system employed by the FBI. It will show the privacy issues that are raised by the FBI's attempt to create an Internet wiretap system. In today's world, where the Internet has pervaded so many aspects of our daily lives, it is important to consider the security of the information one transmits digitally over a network. Ideally, any transmitted data would reach its intended destination without ever being visible to anyone else. Unfortunately, the very nature of computer networks makes this impossible. Carnivore attempts to take advantage of this in order to create the equivalent of an Internet wiretap. However, the present implementation raises certain privacy issues. Carnivore is the FBI's attempt to create the digital equivalent of an analog wiretap. Carnivore functions like many other packet sniffers (network programs that capture all data that they see) that have been available for years; it enters a promiscuous mode where it collects every packet available on the network, whether or not the packet is intended for that machine. Carnivore is then able to piece the packets together in order to reconstruct the original data. The intent is to capture email content without needing to go through the process of obtaining legal access to the files on the mail server of the Internet Service Provider (ISP). However, there is no reason why the same process could not be used to reconstruct other user transactions such as instant messages, chat... ... only methods of precaution available to network users if there is someone sniffing packets. Carnivore poses certain concerns to any network user concerned about their security. Unfortunately many of the issues are in the hands of the FBI and not the common civilian population of the United States, because it does not seem as though Carnivore will be forced to change. As a result, the only safeguard available to most people is encryption of any important information that is transmitted over a network. Public awareness of the issues involved, and the voicing of the concerns could prompt legislation to ensure that personal privacy is observed and respected by the FBI. In the meantime, the FBI will have to be trusted to handle the power provided by Carnivore in an ethical manner, doing everything they can to respect the privacy of the common citizen.

The WWW and Problem Based Learning in Introductory Philosophy :: Education Teaching Essays

The WWW and Problem Based Learning in Introductory Philosophy ABSTRACT: This essay explains how problem-based learning and the World Wide Web (WWW) may be used in collaboration to shift student learning experiences in dramatic ways and to encounter the tasks and concerns of philosophy. We will provide a guided tour of the web site and the problems used in the course, and will describe how these pedagogical strategies may be used to complement traditional classroom venues without making a commitment to offering a course completely on-line for distance learning scenarios. Problem-based learning will also be described and its importance to philosophical instruction will be emphasized. We argue that teaching philosophy by means of problems is more philosophically sound than taking a discrete topical or textual approach. Challenges to this pedagogy are uncovered and discussed. This paper will focus on two significant instructional methods, problem based learning and the use of the web as a teaching tool. It will provide details of the ways in which these two methods have been merged in an Introductory Philosophy class. We will be demonstrating the navigation of our Introduction to Philosophy course web site. I. Problem Based Learning Problem-Based Learning (PBL) is a method of teaching and learning that stresses problem solving activities as a means to encountering and applying knowledge. (Barrows, 1984) It develops out of a strong concern that traditional education stresses the acquisition of factual knowledge without long term retention of that information, the ability to apply the material, the skill to think critically, or the understanding of the context in which knowledge develops and relates. (Norman, 1988, Bridges, 1992, Walton and Matthews, 1989).PBL uses a set of problems - simulations, ethical dilemmas, case studies, medical diagnoses or decisions, legal disputes, public policy issues - as the framework for student learning. The closer the problem is to a real life, relevant problem, the better it functions as a learning motivator. (Bridges, 1992). In traditional lecture and discussion format classes, the instructor introduces the material that he/she deems appropriate and then tests the students knowl edge of the material. In PBL, the student is initially confronted with a problem that requires a solution. The problem drives the student assignments and learning tasks. It is the avenue through which students become acquainted with the material. Barbara Duch says "In a traditional science class, learning tends to proceed from the abstract to the concrete, with concepts being introduced first, followed by an application problem.
