Cultural Challenges in Nursing - 802 Words

It was not merely the ubiquitous presence of death which transfixed but the manner in which death was observed, or denied, as the case may have been. On the oncology unit I first encountered the pervasive silence which surrounds, engulfs and renders nursing complicit. What needed to be stated between physician and dying patient remained largely unsaid. Too often patients were left to discern their fate through a solitary process of elimination. At this stage a keen sense of betrayal gave rise to anger which, for many encompassed the nurses as well. As caregivers we nurses enabled the charade its continuance, administering ultimately futile treatments and emptying emesis basins long after the oncologists ceased making their rounds. My brief time on the unit stunned me, and I became, if not mute, less certain of the efficacy of my own voice. The complex ethical conflict which arose from the silent complicity of the oncology ward ended when my father’s death on the unit which I practiced propelled me from the hospital into community health nursing. (Gorman, 2001) The above observation, similar to my own experience, leaves the writer in a state of dissolution that drives for both personal and professional change. When I began my nursing career I decided on a prison unit at a large teaching hospital because of the wide variety of conditions that were treated there.

Law Dissertation Guide on Provocation as a Defence to Murder. Free Essays

The following article is a dissertation guide produced for a our site client. The Working Title is: â€Å"The problems with provocation as a defence to murder: Has the Coroners and Justice Act 2009 provided the solution for those who suffer from domestic violence and battered women’s syndrome? Part 1 My understanding of the topic The problems with provocation have been well documented in recent years owing to the law commission’s two reports and consultation[1] which have ultimately led to the 2009 Act referred to above. Provocation is a partial defence to murder which reduces such a charge to voluntary manslaughter[2]. We will write a custom essay sample on Law Dissertation Guide on Provocation as a Defence to Murder. or any similar topic only for you Order Now The old Homicide Act of 1957 utilised a two-part test: firstly was the defendant provoked into having a sudden and temporary loss of self-controlSecondly, would a reasonable person have been provoked to react in this wayThe first part was subjective and the second part was objective but there were myriad problems with the old Homicide Act which we must analyse and assess the 2009 Act: the â€Å"cooling-off† period introduced in 1949[3] which attempted to mitigate against calculated revenge discriminates against women who are not so prone to violent outbursts[4], the defence had no moral foundation where someone who was motivated out of compassion would not have the benefit of the defence whereas someone who had lost their temper suddenly was[5], the culture of blaming the victim for their own murder was insensitive[6], the definition of what was capable of provoking a defendant to kill was open-ended and was even stretched to a 17-day old baby crying[7] and finally the very d ivisive schism between the House of Lords[8] and the Privy Council[9] led to confusion on the objective standard: is it proper for the jury to weigh the provocation against a reasonable person who shares the characteristics of the accused? The Law Commission recognised three specific problems:â€Å"In the first report, the three main problems with the existing law were identified as being that: provocation had become too loose so that a judge may be obliged to leave the issue to the jury where the conduct or words relied upon are trivial; the concept of loss of self-control had proved to be troublesome, giving rise to serious problems, to complaints of gender bias, and of the law having to be stretched in the â€Å"slow burn† type cases; and the objective, reasonable person test under the 1957 Act had become too subjectivised in the interpretation given to it in Morgan Smith, enabling a D to rely on â€Å"personal idiosyncrasies which make him or her more short tempered than other people†.†[10] There was clearly a need for reform: of that there is no doubt. But is the Coroners Act 2009 and the new defence of â€Å"loss of self control† under s.56 the solutionNorrie points out that the three problems identified by the Law Commission have been addressed in the new law with the problem now the exclusive preserve of the judge[11], removal of the requirement of a â€Å"sudden† loss of control albeit qualified by a caveat to prevent revenge killing and upholding the Privy Council decision in Holley by in drawing a distinction between â€Å"control characteristics†[12] and â€Å"response characteristics†[13]. But these welcome changes mask some persistent problems such as only age and sex being retained as general characteristics: Norrie rightfully asks what of the immature adult? The New Act just whitewashes this part however and considered that any such questions would undermine the objective test[14]. There is also the question of sexual infidelity which has been expressly disregarded[15]. The test of the reasonable person is now very restrictive, as it follows the Privy Council’s decision in denying factors such as alcoholism, which are extraneous to the object of the provocation, and will deny many the benefit of the defence where they might rightfully expect its protection:â€Å"Anything else that affects the defendant’s general propensity to be provoked, apart from age and sex, is ignored. Thus if a person suffers from alcoholism, this is irrelevant to the loss of self-control unless a taunt was levelled at the fact that the defendant was an alcoholic. If there is not that link, then the defendant must look to the defence of diminished responsibility, even though the characteristic in fact caused them to lose their self-control and to be provoked. This is a significantly narrower test, but an irrational one because it does not address the nub of the problem under the old law.†[16] Norrie argues that the real stumbling block of the new legislation is the lack of moral progress in that there is no moral assessment of the provocatory conduct. Miles agrees and also points out that many who previously enjoyed the test will not now be able to be protected by it and specifically questions whether women with â€Å"battered wives† syndrome will be able to avail themselves of it despite concessions made towards fear as a motivation[17]. Now the Act has came into force and has been operational for 9 months[18]. As yet there are no cases which have made use of it but there have been a few cases which have commented upon it most notably R v Evans[19]which I propose to look at as extensive commentary is made upon the application of the new act which quite simply would have produced a different result.From my preliminary research my hypothesis will be that the new Act is a welcome step in the right direction but that much more work is needed if the proposals of the la w commission are to be fully implemented and brought into line with international standards. To this end I propose examining the legal systems of Canada, Germany and America (which are composed of different legal systems with different traditions) to analyse our new law and see where it stands in comparison. I would also seek to address problems such as erotomania, honour killings and other problems such as provocation for a racist. From all the above research I would propose this structure as a first draft: Part 2 The proposed structure of the dissertation Introduction3 Chapter 1: Background, overview and hypothesis8 The defence of provocation and the Homicide Act 19578 The rupture between the Privy Council and the House of Lords 12 The Law Commission’s involvement in 2004,2006 and 200814 The Coroner’s and Justice Act 2009 15 Theories of provocation: justificatory and excusatory 16 Hypothesis 16 Chapter 2: The abolition of provocation16 Loss of self-control: The offence under the 2009 Act16 Case law involving the new test: R v Evans 18 Case law which has shaped the defence and the legislation 21 Chapter 3: Problems inherent in the new offence 27 The problems with objectivity 27 The omission of sympathetic psychological conditions 28 Discriminating against womenBattered Wives syndrome29 A narrower defence30 Chapter 4: The approach in other jurisdictions30 Germany30 Canada32 America 33 Chapter 5: The future of the defence 35 A case for further reform32 The case to keep the 2009 Act’s reforms34 Chapter 6: Recommendations 38 Reforming the reasonable man38 Psychological conditions: the balance to be struck 39 C. Should the defence be opened up again 39 D. Age and maturity40 E. Sexual infidelity re-established40 Conclusion 41 Bibliography 42 Part 3 Other comments As I have mentioned above the subject is very challenging and interesting and merits a dissertation. The fact that there are no cases so far should allow me to propose some hypothetical examples of cases based on a century of old case law. In terms of research I could look at cases over a ten year period (say leading up to the enactment of the 2009 Act) to look at the success or otherwise of the provocation defence: ie was it truly too expansiveWere women, the victims of domestic violence, really too easily using the defenceFurthermore the latest statistics on domestic violence (2010) have tended to show that men are increasingly becoming the victims of domestic abuse: what are the implications of this?

I had to plunge in and make a lot of snap decisions in these areas. Looking back, I can see one poor strategy decision, but on the whole my judgment has been right on target.

Even if I have to steamroll over someone’s feelings, or ignore the way a colleague would like to handle a project. Sander: Well, I get ticked off pretty easily. For example, I can’t stand explaining something more than a couple of times.

Affirmative Action Essays (2259 words) - , Term Papers

Affirmative Action As Nick Catoggio went to his mailbox, he knew that his acceptance letter from Harvard University had arrived. Although Nick was nervous, he knew that his hard work in high school had gained him admission into one of the world's most prestigious institutions of higher learning. Because of his grade point average of 4.0 in high school, his numerous extracurricular activities, and a combined score of 1440 on his SATs, Nick believed that he would almost be guaranteed admission to Harvard. When he opened the letter however, he was shattered when he read the words, "We regret to inform you ..." He immediately called his friend Richard Sahk, who had also applied, to tell him his news and to see if Richard had received his letter from Harvard. Richard said, "Yeah Nick, I got in!" Nick was astonished. Richard's GPA was only 3.7, and he receive a combined score of 1100 on his SATs. After a long pause he replied, "It's because I'm black, Nick," Richard felt bad for his friend. Both he and Nick had realized that he was accepted by Harvard because of his race. Nick was mad because he was qualified and didn't get in; Richard felt upset because he wasn't as qualified as Nick but was admitted because of his race. This is an anecdotal example of one of the many criticisms of affirmative action. In fact, the whole controversy over preferences based on race and gender has been debated ever since the Civil Rights Act was passed in 1964. I believe that Affirmative action should be discontinued, this program is a new kind of discrimination to counter the past discrimination and this defeats the whole idea of the program. Affirmative action is defined, as a program ensuring that a predetermined proportion of jobs or college admissions go to African Americans and presumably, other minorities and women as well (Woods 102). Also, James Q. Wilson in the winter 1996 issue of The New Republic takes affirmative action to mean the selecting of persons based on their group membership (23). Nicholas Lehman writes that affirmative action today refers to " stuff that helps black people." By this, he says that affirmative action today has come to mean everything from "preferential college admissions to the way news is covered to what's hung in museums to corporate promotional practices" (84). According to Nicholas Lehman, affirmative action started out as Executive Order 10925. Lyndon Johnson, the incoming vice President asked Hobart Taylor Jr., the lawyer son of one of his friends, to work on a draft of an executive order that would ban discriminatory hiring by Federal contractors. Taylor later said that he "was searching for something that would give a sense of positiveness to performance under executive order, and I was torn between the words 'positive action' and the words 'affirmative action.' . . . And I took 'affirmative action' because it was alliterative" (40). Even during Johnson's proposal of the Civil Rights Act of 1964, the issue of racial quotas was controversial. Said then-Senator James Eastland of Mississippi, "... I know what will happen if the bill is passed. I know what will happen if there is a choice between hiring a white man or hiring a Negro both having equal qualifications. I know who will get the job. It will not be the white man" (Lehman 40). The people who seek to abolish affirmative action claim that more qualified students are being displaced by less-qualified students. But there are no more or less qualified students, only students who can benefit from attending a university such as Michigan get a chance, and no one knows in advance who they are. The opinions that accompany the various Supreme Court cases concerning affirmative action have been perplexing, and, at times, contradictory. Woods Geraldine referred to the opinions of the justices as pieces of a puzzle that no one, including the court itself, knows how to solve completely (65). This confusion is probably the result of disagreement among the justices. Many of the cases involving affirmative action have been decided by very close votes. Even when the justices vote the same way, their separate opinions often explain what they agreed for entirely different reasons. Let's take the example of the case, "The Regents of the University of California v. Bakke." On October 12, 1977, the Supreme Court was scheduled to hear case no.76-811. Both proponents and opponents of affirmative action waited to hear arguments about whether a white male, Allan Bakke, should be admitted to medical school at U.C.

A Brief Biography of Gregor Mendel, Father of Genetics

A Brief Biography of Gregor Mendel, Father of Genetics Gregor Mendel, known as the Father of Genetics, is most well-known for his work with breeding and cultivating pea plants, using them to gather data about dominant and recessive genes. Dates: Born July 20, 1822 - Died January 6, 1884 Early Life and Education Johann Mendel was born in 1822 in the Austrian Empire to Anton Mendel and Rosine Schwirtlich. He was the only boy in the family and worked on the family farm with his older sister Veronica and his younger sister Theresia. Mendel took an interest in gardening and beekeeping as he grew up. As a young boy, Mendel attended school in Opava. He went on to the University of Olomouc after graduating, where he studied many disciplines, including physics and philosophy. He attended the University from 1840 to 1843 and was forced to take a year off due to illness. In 1843, he followed his calling into the priesthood and entered the Augustinian Abbey of St. Thomas in Brno. Personal Life Upon entering the Abbey, Johann took the first name Gregor as a symbol of his religious life. He was sent to study at the University of Vienna in 1851 and returned to the abbey as a teacher of physics. Gregor also cared for the garden and had a set of bees on the abbey grounds. In 1867, Mendel was made an abbot of the abbey. Genetics Gregor Mendel is best known for his work with his pea plants in the abbey gardens. He spent about seven years planting, breeding and cultivating pea plants in an experimental part of the abbey garden that was started by the previous abbot. Through meticulous record keeping, Mendels experiments with pea plants became the basis for modern genetics. Mendel chose pea plants as his experimental plant for many reasons. First of all, pea plants take very little outside care and grow quickly. They also have both male and female reproductive parts, so they can either cross-pollinate or self-pollinate. Perhaps most importantly, pea plants seem to show one of only two variations of many characteristics. This made the data much more clear-cut and easier to work with. Mendels first experiments focused on one trait at a time, and on gathering data on the variations present for several generations. These were called monohybrid experiments. He studied a total of seven characteristics. His findings showed that there were some variations that were more likely to show up over the other variations. When he bred purebred peas of differing variations, he found that in the next generation of pea plants one of the variations disappeared. When that generation was left to self-pollinate, the next generation showed a 3 to 1 ratio of the variations. He called the one that seemed to be missing from the first filial generation recessive and the other dominant, since it seemed to hide the other characteristic. These observations led Mendel to the law of segregation. He proposed that each characteristic was controlled by two alleles, one from the mother and one from the father plant. The offspring would show the variation it is coded for by the dominance of the alleles. If there is no dominant allele present, then the offspring shows the characteristic of the recessive allele. These alleles are passed down randomly during fertilization. Link to Evolution Mendels work wasnt truly appreciated until the 1900s, long after his death. Mendel had unknowingly provided the Theory of Evolution with a mechanism for the passing down of traits during natural selection. As a man of strong religious conviction, Mendel did not believe in evolution during his life. However, his work has been added together with that of Charles Darwins to make up the modern synthesis of the Theory of Evolution. Much of Mendels early work in genetics has paved the way for modern scientists working in the field of microevolution.

Individual learning portfoli Essay Example | Topics and Well Written Essays - 2250 words

Individual learning portfoli - Essay Example I might not have thought of value judgments so seriously before. PUL has been designed to provide a holistic learning experience to the student at the university. It presupposes the all too important participation on the part of the student in this once-in-lifetime experience. However, it still reminds the student of the endless opportunities available to students for learning. Thus learning is a full lifetime experience. Individual students’ perception of university learning is determined by a number of factors such as cultural influences, socio-economic influences and personal attitudes. My own attitudinal perspectives on PUL are coloured by such factors as my own perception of individual liberty and economic status. The whole process of education at the university has been exceedingly rewarding and primarily reorienting. PUL has afforded me a vantage point in understanding the process of education. I might have deliberately avoided examining my inner feelings towards university education at the outset for the fear of exposing myself to prejudices of fellow students. PUL plays a pivotal role in awakening in students a desire for self-learning that promises a paradigmatic shift in attitude and individual experience. Despite a host of much hyped liberties in non-institutional environments of learning, the experience of such learning has little or no rewards. Thus, PUL as a subject provides the student with a much wider scope to embark on a pursuit of self-interest. There are some implications of such a program of study though. For instance, at times I happen to entertain qualms about the so called futuristic dimension of a subject that has more to do with university culture and environment. Personal predilections and positive or/and negative marginal propensities all play a major role in this sensitive issue. My own senses and sensibilities very rarely find a medium for expression. But PUL has provided me with that

Teenage pregnancy in the uk and possible strategies to prevent it Research Proposal

Teenage pregnancy in the uk and possible strategies to prevent it - Research Proposal Example It is for these reasons a policy was evolved in early 1990s to reduce the rate of teenage pregnancies progressively and to reduce it by at least half by the year 2010. The brief literature review shows teenage pregnancies do not show any signs of abating and the problem is exacerbated by the tendencies of the teenagers giving a second birth before they reach 20 years. There are also fears that babies born to teenage mothers will themselves become teenage mothers due to built-in culture developed over generations. Systematic literature review is the sole research methodology adopted for the dissertation. The above results of literature review conducted justify a detailed secondary research further on the issue of teenage pregnancies in the U.K. This proposal is for a dissertation as part of the researcher’s B.Sc. Health field curriculum at the University of East London at the end of the degree in level III. The chosen topic is â€Å"Teenage Pregnancy In The UK And Possible Strategies To Prevent It† on which the researcher is required to make a systematic literature review as a secondary research. Teenage pregnancy worldwide is causing concern as it is associated with girls’ health mostly as unwed mothers susceptible to mortality as child bearers at the adolescent age without full grown body and HIV and Sexually Transmitted Infections (STI) Half the world population comprises of people, less than 25 years of age. People between the ages 10-19 are adolescents. The adolescents in their second decade of life contract STIs, HIV/AIDS more than any other age group. This target population is the hope for governments to substantially reduce the incidence of the said diseases. Only a very few countries have achieved limited incidences of STIs and HIV mainly by teaching their adolescents safe sexual practices. Among U.S., Canada, France and the U.K., the U.K. has

A report on application of technology in Operations Management Essay

A report on application of technology in Operations Management - Essay Example This forms the revenue-generating function of any business and thus based on five critical strategies such as speed, flexibility, dependability, quality and cost. All operations activities are carried out based on these strategies. In order to continuously enhance effectiveness of these strategies, various technology services are employed in operations management through advanced information technology and information service (IT/IS) systems. This report evaluates application of IT/IS in various operations activities and their impact on its core strategies. 2. Operations management and strategic objectives: The entire operations/production process is accomplished using resources such as money, raw material, equipment, manpower and finance. These inputs are processed in specific manner through a sequence of preplanned activities in order to produce desired outputs, which can be in the form of completed parts, products, chemicals, service to customers, completed paperwork etc. Operatio ns strategy controls the strategic position of the firm, and is aligned to the overall corporate strategy. This alignment is to ensure all policies and plans reinforce organizational effectiveness and aid in optimum production of goods and services. For example, Toyota’s operations strategy includes designing, assembling and marketing the finished products, but procures the rest from other suppliers (Feist et al, 1999). This strategy is aligned to its corporate strategy of producing defect-free products, in less time and occupy largest market share. In general, operations strategy involves decisions related to design of the process of production or service providing as well as facilities and/or infrastructure needed to support the process. To achieve such tough and complicated objectives, organizations make optimum usage of advanced information and technological services. The IT services form a part of their tactical planning approaches, which also include capital, human reso urces, technology, facilities; staffing and scheduling methodologies to achieve target productions; sales and service operations; inventory management of supplies and delivered goods etc. In addition, short-term operations planning activities such as capacity, quality control, inventory, manpower etc also require IT services for effective operations. 3. Practical applications of IT for objective achievement: The three major components of corporate strategy in any business include operations effectiveness, customer management and production process and innovation (Chase 2006). Information Technology (IT) provides strong platform to convert, store, protect, process, transfer and recover information related to operations, customer and production processes. IT and its systems are used in all operations management processes such as capacity planning, inventory control and management, quality control, human resources management, etc. All business processes such as taking orders from custo mers, handling returns, manufacturing, marketing, delivery of end products also require IT systems. IT finds effective application in all customer management activities such as evaluation of customer feedback, customer satisfaction, customer expectations etc. Application of IT for innovation in operations and production management is mainly through research and development activities. According to Slack et al. (2004) the main objectives of operations manage

Bangladesh Liberation War: Conflict Analysis

Bangladesh Liberation War: Conflict Analysis Conflict Analysis Case Study –Bangladesh Liberation War Background and Internal Factors West Pakistan had four provinces: â€Å"Punjab, Sindh, Balochistan, and the North-West Frontier.† Province number 5 was East Pakistan, and it was the largest province out of all. West Pakistan had control over all the provinces, and used up most of the resources. â€Å"Between 1948 and 1960, East Pakistan made 70% of all of Pakistans exports, while it only received 25% of imported money. In 1948, East Pakistan had 11 fabric mills while the West had nine. In 1971, the number of fabric mills in the West grew to 150 while the number in the East went down to 26. About 2.6 billion dollars of resources were also shifted over time from East Pakistan to West Pakistan. Although East Pakistan had the largest population among all the provinces, it had much less political power than West Pakistan. Although the economy was an issue, there was also the issue of language that caused East Pakistan and West Pakistan to have dispute for several years.† (bdallinone) In 1948, Mohammad Ali Jinnah announced that Urdu was the official language for Pakistan. However, this was not fair because only the people in the West and the Bihari’s in the East spoke Urdu. Majority of the West Pakistanis spoke Punjabi and Sindhi, while East Pakistanis spoke Bangali. Therefore, East Pakistan was against the movement of Urdu being the official language for Pakistan. Sheikh Mujibur Rahman, the leader of the Awami League (top political party in support of East Pakistan), wanted more economic and political power, all of these political changes resulted in the war of independence. The war involved two parts of Pakistan: East Pakistan VS West Pakistan in a war for liberation and freedom from West Pakistan. The war lasted throughout March 26th – December 16th 1971. The Pakistan Army began a genocide called â€Å"Operation Searchlight† by attacking the innocent Bangaladeshi’s of Dhaka city (Dhaka is the capital city of the province Bengal). The Pakistani army massacred 40,000 Bengali people, whether they be poets, teachers, police officers, etc and ignited a brutal war against the Bengalis of East Pakistan to stop them from being independent. They also invaded homes and held families on gun point, burned down schools, destroyed sacred architecture and purposely ruined 80% of agriculture lands, which caused Bangladesh to be in a famine. They killed sons and daughters and raped women and the West Pakistani army got away with ALL these crimes, and nothing was accounted for until at least 30 years ago, when activists convinced the police department to open up old cases. East Pakistan didn’t have an army since it was not yet officially a country, so they were just a group of freedom fighters. Eventually, India joined in to support East Pakistan’s Freedom Fighters, and then they formed the Mukhti Bahini, which translates to The Liberation Army. They used the guerrilla method and just basic armed forces, which they got from the support of the Indian Army, and through a lot of gruesome war, they eventually fought until they gained their liberation, and Bangladesh was declared an independent nation. The West Pakistani government was not willing to make peace with the East Pakistani government due to political differences such as political power due to economic, language and racial issues, since West Pakistan was considered one large province, the politicians that were on the West Side did not allow East Side of Pakistan to develop their own stable government since the East Side always got outweighed. External Factors Throughout the war, there was involvement from several other countries such as India. India played an active role. Indira Gandhi (Prime minister of India) wanted to protect Bangladesh. Since India had a lot of protection (bombs, nuclear weapons, great military), they â€Å"mounted a three-pronged movement on Dhaka from the Indian province West Bengal, Assam, and Tripura. The Indian soldiers, Air Force, and Navy defeated the Pakistani army, while the Bangladeshi Navy helped India. On the ground, three groups of Mukti Bahini and Indian forces fought the Pakistanis. The Pakistanis attempted to fight back and they did not give up, but failed to resist them and ended up surrendering† (Murtala Sadeh) This surrender was the largest surrender from an army since World War 2. This was not a proxy war because the East Pakistan and West Pakistan communicated directly with each other, and did not use any other source to have the war fought for them; they fought on each other’s land. International Response: United Nations Pakistan’s plan to invade and bomb India’s land got the United Nations involved, and they stepped in and tried to force India to agree to a cease-fire. The â€Å"UN Security Council† came together on December 4 1981 to talk about the situation and find any possible way of making peace. After much convincing and long discussions, on 7 December, the United States came up with the idea for an immediate ceasefire and withdrawal of troops. Stalinist Russia rejected the resolution twice. In light of the Pakistani atrocities, Britain and France restrained and kept their distance from the situation. The Indian army quickly overran the country. Pakistani forces were unable to effectively fight the brutal attacks, since â€Å"they had been deployed in small units around the border to counter guerrilla attacks by the Muhkti Bahini. Unable to defend Dhaka, the Pakistanis surrendered on 16 December 1971, the largest surrender since the Second World War. Bangladesh gained adm ission to the UN with most voting in its favour, but China rejected this as Pakistan was its key ally, as was the United States, which was one of the last nations to accord Bangladesh recognition. United States of America â€Å"The US administration feared that an Indian invasion of West Pakistan would mean the domination of the region by Stalinist Russia. That, in turn, would seriously undermine the global position of the US and the regional position of America’s new tacit ally, China. In order to demonstrate to China the reliability of the US as an ally, and in direct violation of the US Congress-imposed sanctions on Pakistan, Nixon sent military supplies to Pakistan, shipping them through Jordan and Iran. China was encouraged to increase arms supplies to Pakistan†. (Wikipedia) The Nixon government completely uncared for the reports it received of the genocidal and brutal activities that the Pakistani Army was getting involved in (to dominant the Bengalis), including all the deaths of innocent Bangali’s and all of the rapes. However, Russia supported the Indian army and Mukti Bahini during the war because they knew that the independence of Bangladesh would make their rivals weaker. It also assured India that if the US or China tried invading India, Russia would have their back. Therefore, the Indo-Soviet friendship treaty was signed in August 1971 during the Bangladesh Liberation War. When Pakistan’s defeat was obvious, â€Å"Nixon sent the aircraft carrier, USS Enterprise, to the Bay of Bengal, a move which ratcheted up nuclear tensions in the region. USS Enterprise arrived on station on 11 December 1971. On 6 and 13 December, the Russian navy sent out two groups of ships, armed with nuclear missiles, from Vladivostok. They trailed the US task force in the Indian Ocean from 18 December until 7 January 1972. At the end of the war, the Warsaw Pact countries of Central and Eastern Europe were the first to recognise Bangladesh as an independent country.† (Wikepedia) Stalinist Russia gave credit to Bangladesh on 25 January 1972. The United States also eventually gave them credit in April. â€Å"On 2 July 1972, the Simla Accord was signed between India and Pakistan, which stated the goal to normalise relations between India and Pakistan, including the return of Pakistani prisoners of war. Pakistan officially recognised Bangladesh in 1974†. (Wikiped ia) China Since China is an ally of Pakistan, the Peoples Republic of China reacted with productively towards situation in East Pakistan and the prospect of India invading West Pakistan. They know that an Indian attack was about to happen, so Richard Nixon (President of U.S.A) encouraged China to gather together its armed forces along India’s border. The Indian Army was prepared and had deployed eight mountain divisions to the â€Å"Sino-Indian border to guard against such an eventuality.China instead threw its weight behind demands for an immediate ceasefire.† (Wikipedia) When Bangladesh wanted a place to get involved in the United Nations in 1972, China rejected their application because of two United Nations resolutions regarding the repatriation of Pakistani prisoners of war and civilians had not yet been implemented.† (Wikipedia) China was one of the last countries to recognise the liberation of Bangladesh and denied to until 31 August 1975. Effect of Temperature on Plant Physiology | Experiment Effect of Temperature on Plant Physiology | Experiment Abstract The physiological processes of many organisms are sensitive to temperature. In order to see this effect of temperature, we examined the heart rate of a Daphnia magna over a range of different temperatures. Being an ectothermic animal, the Daphnias body temperature is dependent on water temperature. It was hypothesized that since most physiological processes are faster at higher temperatures, the Daphnias heart rate will be faster at higher temperatures and slower at low temperatures. This was, in fact, true and a pattern was evident which showed that heart rate increased as temperature increased. The Q10 was high at higher temperatures which show elevated sensitivity at higher temperatures. Clearly, Daphnia have an optimal temperature range outside which they do not function to their full potential. A Daphnias heart rate, then, was proved to be dependent on temperature. Introduction Daphnia magna is a widespread freshwater zooplankton. Since Daphnia are ectothermic animals, their body temperature fluctuates with environmental temperature. Hence, these animals are ideal to study the effects of temperature. Most such animals function well at certain specific temperatures. They have an optimal temperature range, outside which they are unable to perform physiological processes effectively (Lamkemeyer et al. 2003). It is believed that most physiological processes take place more rapidly at higher temperatures and that changes in temperature can influence physiological rates (Ziarek et al. 2010). In order to investigate this, we questioned whether the heart rate of a Daphnia is different at different temperatures. Q10, which is the temperature sensitivity of a reaction, was a useful tool. We hypothesized that the Daphnia will have different heart rates at different temperatures and hence that temperature will affect heart rate. It was also hypothesized that Q10 will d iffer at different temperatures. This hypothesis was tested by exposing the Daphnia to different water temperatures, letting it equilibrate to the water temperature and counting its heart beat in a systematic way. Since most physiological processes increase at higher temperatures, we predicted that if the temperature is higher (close to 35 °C) then the heart rate of the Daphnia will be faster and if the temperature is low (close to 5 °C) then it would be slower. In addition, we predicted that Q10 will be higher at low temperatures and lower at high temperatures. In view of the fact that Daphnia had an optimal temperature range, it would be understandable if the Daphnia was more sensitive to temperatures outside this range and consequently reacted by altering its heart rate. Methods A Daphnia was placed on a small smear of Vaseline on the bottom of a culture dish (Olaveson and Rush 2011). Aged water at room temperature was added to the dish. Five minutes were allowed for the Daphnia to adjust to the water temperature and the temperature of the water was measured and recorded. Under a dissecting microscope, the Daphnia was placed and the 4X lens were used to locate the heart and count the heartbeats. The number of beats was counted over a 10 second period which was followed by a 10 second pause in counting and then 10 seconds of counting again. In order to get 9 measurements of the heart rate, this pattern was repeated for 3 minutes. Then, ice and water were mixed in a beaker to make a water mixture between 5 °C to 10 °C. To replace the tap water in the culture dish with chilled water, a Pasteur pipette was used. Five minutes were allowed for the Daphnia to reach equilibrium and then the heart beat was counted to obtain 9 measures of heart rate (heartbeats/ 1 0 seconds). The values were recorded. The temperature was then increased in 5 °C increments till 35 °C and heart rate was measured at each point. Small amounts of the colder water were replaced with the warmer water (obtained from a water bath) till the desired temperature had been reached. Five minutes were always allowed for equilibration and using the same method, 9 measures of heart rate were recorded. The 9 estimates of heart rate taken at each temperature were used to find the average heart rate at each temperature. These values were entered into an excel document by all students and later used for analysis. Results Statistical analysis and data processing shed light upon the effect of temperature on the heart rate of a Daphnia. The Statistical t test analysis proved that the Ho could be rejected for all the three tests proving that temperature does have a significant effect on the heart rate of a Daphnia. The Q10 as well as the average heart rates at different temperatures provided evidence that supported the hypothesis that temperature would affect Daphnia heart rate too. At the temperature interval of 4 °C to 14 °C, the Q10 was found to be 1.31 (Table 1). Although this was not the highest Q10 value and hence not the most sensitive temperature interval, a decrease in heart rate was evident at the lower temperature of 4 °C compared to other higher temperatures (figure 1). The heart rate at 4 °C was found to be 106.74 beats per minute where as the heart rate at 14 °C was 140.10 beats per minute. The significant decrease in heart rate at 4 °C compared to heart rate at the ambient temperature (24 °C) was supported by the t test analysis (sample t statistic: 14.3938; critical t statistic:1.978; df:136; p = 0.05). The temperature interval from 14 °C to 24 °C showed increased sensitivity (Q10:1.40). This indicated the increase in heart rate at 24 °C compared to lower temperatures (figure 1) and was supported by the t test analysis as the Ho (hypothesis that no change in heart rate would be evident) was rejected (t statistic: 8.6519; criti cal t statistic:1.978; df:136; p = 0.05). During the temperature interval from 24 °C to 34 °C, the highest Q10 was noted (table 1). This sensitivity to high temperatures was obvious when heart rates at the two temperatures were compared (heart rate at 24 °C: 196.32 beats/min; at 34 °C: 277.92 beats/ min). The H0 was hence rejected (t statistic: 9.7792; critical t statistic: 1.978; df: 136; p = 0.05). All the three tests provided evidence that suggested that temperature had an effect on the Daphnias heart rate. At higher temperatures, the heart rate was faster and at lower temperatures, it was slower. Generally, as temperature increased so did the Daphnias heart rate (figure 1). Discussion All organisms have an optimum temperature range over which they function best. Consequently, at certain temperatures, the physiological processes of a Daphnia magna are at its utmost potential. Some hypothesized that Daphnia optimize their fitness by allocating the time spent in the different habitats depending on the temperature gradient (Kessler Lampert, 2004). Hence, evidently temperature has an effect on the performance of a Daphnia. Specifically, as hypothesized, temperature affected the heart rate of Daphnia. It was noticed that the Daphnias heart rate increased at higher temperatures (close to 34 °C) and decreased at lower temperatures (close to 5 °C). Since Daphnia are ectothermic, their body temperature varies with environmental temperature. Since Daphnia cannot thermoregulate, their body temperature experiences variance following à ¯Ã‚ ¬Ã¢â‚¬Å¡uctuations in the environment (Ziarek et al. 2010). Hence as the temperature of the water increased, so did the Daphnias heart rate. The data supported this prediction. This is simply because most physiological processes take place more rapidly at higher temperatures. In addition, research has shown that increases of heart rate by significant values were measured in D. Magna as a function of temperature (Paul et al. 2004). One reason why the heart rate of Daphnia increases with temperature would be because less oxygen is present in the warmer water. Consequently, lack of oxygen could result in insufficient amount of oxygenated blood and hence the heart would have to work harder to pump blood around the body. For this purpose, it makes sense that the heart rate would increase. Very little research has been done about oxygen levels at different temperatures and Daphnia heart rates and perhaps more such research will provide more clarity on this topic. The little research that has been done, though, suggests that a reduced aerobic scope allows only time-limited survival at temperatures outside the optimal ran ge (Lamkemeyer et al. 2003) in organism such as Daphnias. Other research has also shown that high temperatures increase a Daphnias metabolic rates by increasing their heartbeat rates (MacArthur Baittie, 1929), and consequently their oxygen demands (Ziarek et al. 2010). It is also important to note that although it was predicted that Q10 would be higher at low temperatures and lower at high temperatures, the data did not support this prediction. The opposite, in fact, was evident. At higher temperatures the Q10 was higher and at lower temperatures it was lower. This could be possible merely because the Daphnia was more sensitive to changes in temperature at higher temperatures. It could also be possible that Q10 was higher at higher temperatures because of other errors. For instance, when the ice was added to the water in order to obtain low water temperatures (5 °C), it was difficult to obtain the exact temperatures. Although the temperature obtained (about 8 °C) was lower than room temperature (or ambient temperature), it is possible that it wasnt low enough to trigger major physiological changes. A significant fact to keep in mind is that since temperatures are increasing due to global warming, water temperatures are going to increase as well . This could lead to problems for organisms such as Daphnia which cannot function well outside of their optimal temperature range. It has been suggested that rising temperatures associated with global warming present a challenge to the fate of many aquatic organisms (Doorslaer et al. 2009) In conclusion, Daphnia heart rate is affected by temperature and tends to increase at high temperatures and decrease at low temperatures.

The Insanity Of Hamlet :: essays research papers

In William Shakespeare?s Hamlet, Hamlet leads an antic disposition that causes his downfall and leads him to insanity. His antic disposition affects his judgment, destroys relationships and creates a belief that he is truly mad. Throughout the play, Hamlet is consumed with anger which causes him to act through emotion and without reason. Hamlet?s main goal is to avenge the death of his father but, his actions to do so are hindered because of the irrational decisions he has made through the antic disposition he has put on. Hamlet?s antic disposition began with the death of his father. Hamlet returns to his home, Denmark, to find King Hamlet, his father, dead. As any normal human being would be allowed to grieve, Hamlet was not. Hamlet was expected to accept the death of his father and move on. (Do not forever with thy vailà ¨d lids/Seek for thy noble father in the dust./Thou know'st 'tis common. All that lives must die,/Passing through nature to eternity.)(1.2.68-73). Without the ti me to grieve, Hamlet was left with the echo of his mother?s and Claudius?s hurtful and unsympathetic words of advice. While Hamlet was forbidden to ?useless mourning? (We pray you, throw to earth/This unprevailing woe, and think of us/As of a father.)(1.2.106-108), his mother quickly marries to his uncle Claudius and undoubtedly moves on with her life. In T.S. Eliot?s The Sacred Wood, Hamlet?s ?disgust envelops and exceeds her. It is thus a feeling which he cannot understand, he cannot objectify it, and it therefore remains to poison life and obstruct action.? With little time to grieve and a mother that seems to care less about her deceased husband, Hamlet?s mind was given the perfect recipe for insanity. In mid night, a mysterious ghost appears to Prince Hamlet in the shape of his 2father, King Hamlet. The strange and mystifying ghost guides Hamlet away from Horatio and Marcellus, as if wanting privacy. Hamlet becomes defensive and mad and believes his fate is to follow the ghos t, ?My fate cries out/And makes each petty artery in this body/As hardy as the Nemean lion's nerve./Still am I called.?Unhand me, gentlemen.?(1.4.86-89). Hamlet is determined to hear the words of the ghost and threatens Horatio and Marcellus to death if they do not let him go. Horatio and Marcellus follow him for his safety but believe ?He waxes desperate with imagination.?(1.4.92). The ghost is the first obvious sign that Hamlet?

Plastics Bags: A Devil To Be Banned

Plastics Bags- A Devil To Be Banned Plastic bags are normally given to customers by vendors when buying. It is a very convenient method for transporting goods. Moreover, it is highly popular to the customers and retailers because of its light weight. But, ultimately this much usage of the plastic bags leads to the many serious problems. Plastic bags should be banned in Canada because it have a critical environment problems, health problems and also because of its cost of production and recycling. Plastic bags should be banned because it creates very harmful environment problems.Throwing plastic bags could make the soil pollution. It also creates marine pollution. As per the research â€Å"over 13 billion plastic bags are handed to consumers each year, representing a substantial proportion of all floating marine litter (http://www. guardian. co. uk/ environment/2007/nov/13/plasticbags. pollution). Plastic bags wastes block the drainage and also it is dangerous to marine life. Every y ear thousands of seals and whales are dying because of eating plastic bags. For making a plastic bags earth’s precious natural resources are being used.Burning plastics produce much polluted gases which cause air pollution (http://debatewise. org/debates/ 1011-should-plastic-bags-be-banned/#yes9). All of this pollution in combine produces a Green House Effect. Moreover, during the production of the plastics many harmful waste chemical is produce which also contribute in the pollution and ultimately environment problems. So, plastic bags should be banned in Canada as it has dangerous environmental issues. Another, reason for banning of the plastic bags is because of its effect on the health.Air produce after burning of plastics can lead to an asthma or can worse the asthma. When a plastics break down it release many harmful chemicals and by drinking this type of water it enter into a human body and can produce a disease like diabetes, heart problems, cancer (Copperkitten). The se all health problems are serious and they cost much for treatment also. â€Å"Toxic emission produces daring an extraction of plastic bags, their manufacturing, and their transportation contribute to acid rain and smog† (Environmental Literacy Council).Moreover, some people put their foods in plastic bags for a long time and during that many toxic chemicals enter into a food and that may degrade food and also have an adverse effect on a health. Sometimes animals eat plastics bags with other food and in the body plastics not get metabolized and cause the serious problems. Many times it happen like birds eat a part of plastic bags and that stick to their neck and because of that they are unable to take a breath, and die. That’s why the usage of plastic bags should be banned in Canada due to its health risk.Production as well as recycling of plastic bags is very costly. During a production many natural sources of energy are used and that increase the production cost. Mo reover, this will leads to a decrease of these types of an energy sources. The price of oil used to produce petrochemicals for making recycled plastics is so high (Miller, 2005). One could drive their car for a few meters in production cost of one plastic bag. Also, the plastics are non-biodegradable so recycling is very complicated and it will cost too much money.After the recycling another big problems is of removal of the waste. Overall, production and recycling of plastics bags affect the economy of the country. For recycling there are a separate bins required to put in each street and also special vehicles are required for collection of that bins, and these all ultimately increase a cost of recycling. For a disposal of non-biodegradable plastic bags separate farmyard is required and day by day more and more space required storing plastic wastes. Therefore, it is better to ban a usage of plastic bags and it must be banned.Some people give a counter argument that plastic bags sho uld not be banned in Canada. They give a reason like plastic bags are convenient, cheaper and also not harm the environment too much. Some says, it is better to add a tax on production and usage of plastic bags than banning it. But it is not necessary that all convenient things are good for environment and economy. Moreover, the plastics are never degraded into a harmless ingredient, it always produce a toxic substances. Another way to reduce the environmental problems is to use a bio degradable plastics bags.But, the production cost is too high for making bio degradable plastics bags. Some says to reduce the use of plastics bags rather than banning it. But, nobody can control the usage of plastics if it is not banned. And it is proven that the plastic leads to critical environmental problems. It also reduces the other sources of energy and that will affects lot in future. And there is no need to use plastic bags as paper bags already available at the same cost in a market. Also, su ch types of paper bags are bio degradable as well as safe for a environment.So, plastic bags must be banned in Canada. In a nut shell, due to the high risk associated with the usage of plastic bags, it should be banned in Canada. Nobody have a right to damage a environment of a earth. So for a environment and for other living creatures usage of plastic bags must be stop and that is only possible by banning of a usage as well as production. In such types of issues awareness is not much useful. Government must have to take a firm steps for it. And, banning of plastic bags is only a solution.Work cited Copperkitten: Sustainable Living, June 2010 http://copperkitten. wordpress. com/2010/06/22/the-health-hazards-of-plastic-bags/ Environmental Literacy Council. 2005. â€Å"Paper or Plastic? † November 20, 2005. http://www. enviroliteracy. org/article. php/1268. html Miller, G.

Andromeda Strain essays

Andromeda Strain essays Michael Crichton uses three common devices with ease in his novel, Sphere. The devices being: rhetoric, semantics, and style. Crichton uses these devices to incorporate a sense of unity in the writing. It is not difficult to incorporate this unity into a novel when the devices are properly used. When doing so, they flow together to create a more visual experience for the reader. These devices of writing are what create the environment for an understandable, yet interesting storyline. Rhetoric is the art of using language effectively and persuasively. In doing so, the use of rhetoric fits in with how the writer of the story thinks and speaks. Crichton is an intellectual, yet he does not write in a sense where the reader cannot understand. He chooses to discuss many intellectual concepts, but in the process, Crichton makes them easy to understand by explaining them simply. The wasnt geometric. And it wasnt amorphous or organic, either. It was hard to say what it was. (Crichton, 117) In this excerpt, Crichton makes reference to a pattern. He describes it enough to leave the feeling of not knowing what it is besides just a simple pattern. Therefore, creating the feeling in which the characters feel. Semantics refer to the study of language forms. In Sphere, the language is not too different. Every character in the novel is in fact an intellectual in one form or another. They speak correct grammar, and communicate well with each other. The social environment, which is formed, makes for smooth transitions of communication. The linguistics Crichton chose to use made the novel more appealing to the average reader. Style can be defined as the way the author chooses to portray the characters and setting in his story. Crichton picks a parallel in his novel. The plot of Sphere deals with space exploration and alien existence. Yet Crichton does not put the setting in outer space, but in the dee...

Calculations With the Gamma Function

Calculations With the Gamma Function The gamma function is defined by the following complicated looking formula: Γ ( z ) ∠«0∞e - ttz-1dt One question that people have when they first encounter this confusing equation is, â€Å"How do you use this formula to calculate values of the gamma function?†Ã‚   This is an important question as it is difficult to know what this function even means and what all of the symbols stand for. One way to answer this question is by looking at several sample calculations with the gamma function.   Before we do this, there are a few things from calculus that we must know, such as how to integrate a type I improper integral, and that e is a mathematical constant.   Motivation Before doing any calculations, we examine the motivation behind these calculations.   Many times the gamma functions show up behind the scenes.   Several probability density functions  are stated in terms of the gamma function. Examples of these include the gamma distribution and students t-distribution,   The importance of the gamma function cannot be overstated.   Γ ( 1 ) The first example calculation that we will study is finding the value of the gamma function for Γ ( 1 ). This is found by setting z 1 in the above formula: ∠«0∞e - tdt We calculate the above integral in two steps: The indefinite integral ∠«e - tdt -e - t CThis is an improper integral, so we have ∠«0∞e - tdt limb → ∞ -e - b e 0 1 Γ ( 2 ) The next example calculation that we will consider is similar to the last example, but we increase the value of z by 1.   We now calculate the value of the gamma function for Γ ( 2 ) by setting z 2 in the above formula. The steps are the same as above: Γ ( 2 ) ∠«0∞e - tt dt The indefinite integral ∠«te - tdt- te - t -e - t C.   Although we have only increased the value of z by 1, it takes more work to calculate this integral.   In order to find this integral, we must use a technique from calculus known as integration by parts. We now use the limits of integration just as above and need to calculate: limb → ∞ - be - b -e - b -0e 0 e 0. A result from calculus known as L’Hospital’s rule allows us to calculate the limit limb → ∞ - be - b 0. This means that the value of our integral above is 1. Γ (z 1 ) zΓ (z ) Another feature of the gamma function and one which connects it to the factorial is the formula Γ (z 1 ) zΓ (z ) for z any complex number with a positive real part. The reason why this is true is a direct result of the formula for the gamma function. By using integration by parts we can establish this property of the gamma function.

Qualitative VS Quantitative Research Essay Example | Topics and Well Written Essays - 750 words

Qualitative VS Quantitative Research - Essay Example When we think about research, things that come to our mind are e.g. facts & figures, science, observation, logic, evaluation, etc. etc. Adopting the scientific approach and adhering to a focused approach to come-up with certain findings do not contain values, passions, politics and ideology of the researcher. Using this kind of research methodology is called a â€Å"positivistic† approach and it is the most commonly used approach in general public. In short, the qualitative research refers to the existence of reality which is analyzed and understood with less rigorous methods and procedures while the quantitative research is aimed to reach to an objective (quantified) solution on the basis of cause & effect and examining theoretical relationship into a practical scenario. However, the emerging social changes and globalization are posing ineffectiveness of traditional deductive approach and forcing social researchers to opt for the inductive approach. Assessing qualitative research through a social constructionist lens, however, is premised upon the belief that research findings are always already partial and situated; that they actively construct the social world which is itself an interpretation and in need of interpretation. If we reject the very notion of an empirical world untouched by the social and the political, how are we to assess the research claims we make? If we concede that â€Å"truth† and â€Å"objective knowledge† cannot be invoked unproblematically, upon what grounds are we to say one research claim is better (i.e., valid) than another?. It is a kind of cold war between the old and new generation qualitative researchers. The latter reject the quantitative, positivist methods and assumptions. Having poststructural and/or postmodern sensibilities, they argue that positivist methods are nothing but all about telling stories about societies. Many new qualitative researchers are of the opinion that these methods do

Wal-Mart Capital Structure and Financial Analysis Essay

Culture and Organization - Essay Example Additionally, organizational culture extents its manifestation in ways which an entity allows for autonomy and freedom of making decisions, personal expression, and development of new ideas. Organizational culture gives a clear outline on how information and power flows through its set channels and influences strengths of employees by encouraging commitment towards the organization’s collective goals (Stallman, 2010:4). The culture of an organization is crucial since it affects its productivity and performance mechanism and provides guidelines suitable for establishing an appropriate customer service channel, product quality, and safety. Introduction Southwest Airlines Company is a low cost, American airline that has its base in Dallas, Texas. According to articles published the company’s public relations office, the company came into being in 1967. It adopted its company name in 1971 and by the fifth day of June 2011, documented evidence revealed that the airline is th e largest in the United States basing the data on number of domestic passengers that it carried (Kelly, 2009:22). Despite the fact that the airline operated Boeing 727 aircraft for a very time in the years between 1970s and 1980s, between this stated period and 2012 the scooped identity of the sole airline that operates Boeing 737. In addition to that, by the last day of September 2011, this airline became the world’s largest operator of 737 recording over 550 of these aircrafts already in operation whereby, each operated an average of six flights in a single day. Following its performance and uniqueness, this paper warranted it an intense research based on its organizational culture (Khastar, 2011:2). As such, this paper will seek to analyze the culture of the Southwest Airlines using and applying theoretical frameworks used in the study of organizational culture such as those developed by Schein and Harrison. The concept of organizational culture With reference to Schein th eoretical framework, the processes whereby the Southwest Airlines became the largest Boeing 737 operator in America and globally as well, led it reproduce its systems and practices of management in order to gain competitive advantages over other airlines eyeing the same uniqueness. Nevertheless, despite the fact that it sough to reproduce its management practices as closely as possible, the results were rarely compatible. Generally, the managers encountered issues they did not have to face in the operating environment (Achtmeyer, 2002:2). This is the reason as to why the first notions of culture used by the managing team were so similar to those deployed by the company with the view of defining the national culture. At this point, the development of the concept of organizational culture was ultimately polemic as opposed to what took place with other theoretical constructs such as organizational climate. Scholarly research reveals that, the concept of an organizational culture is a t hing borrowed from basic social sciences, mainly sociology and anthropology (Flamholtz and Randle, 2011:83). As opposed to organizational climate, which is a product of a conducted research, the concept of an organization is a construct embedded in the theoretical framework that employs the use of organizational environment and academics to listen to management theory (Bundgaard, Bejjani, and Helmer, 2006:16). Given the power of the Southwest

Dramatic principle Essay Example for Free

Dramatic principle Essay The Prelude is a long autobiographical poem, described the poets love of nature and his own place in the world order. Dust as we are, the immortal spirit grows Like harmony in music; there is a dark Inscrutable workmanship that reconciles Discordant elements, makes them cling together In one society. The Prelude had a great influence in prose poetry (Nichols 66 as quoted by Moore). Lyrical dialogue can be observed in it which shows that through Prelude, he wanted to move away from the monologic lyric. His breaking out from the monologic lyric has created the prose poem. The significant idea that the form of the poem should reflect the experience is denoted by his short poems (Rehder 179 as quoted by Moore). He desired for irregular forms to experience uniqueness (Rehder 206 as quoted by Moore). The poetic genres free verse and prose poetry are actually developed from that idea of uniqueness. Robert Browning had won himself the reputation of a dramatic poet and was able to produce the dramatic monologues. Though at his time a dramatic monologue was not yet a genre, this is considered now as a poetic genre with intriguing characteristics in a sense that it gripped the minds of the scholars. This genre has a characteristic of modern criticism. However, modern criticism stresses on the dramatic part, the dramatic monologue stresses the lyrical characteristics. His monologues incorporate action and conflict in the drama thus it involves outpouring of emotions. It is clearly evident in his work that it is a mixture of lyrical and dramatic (Abou-Bakr). Browning’s collection the Dramatic Lyrics shows his concept of poetic genre particularly about being lyrical and dramatic. It seems that Browning saw the dramatic principle by employing the creation of fictional characters who will take the role of the speaking voice I his poems. These characters or the so-called personae are the ones giving the lyrical utterances or expressions. To Browning, lyrical and dramatic can be differentiated by its proximity from the poet himself. The Confessional exposes not the sin of the persona however it reveals the sin of the priest. It was actually lightened by the humor incorporated in it. You think Priests just and holy men! Before they put me in this den I was a human creature too, With flesh and blood like one of you, A girl that laughed in beautys pride Like lilies in your world outside. The fathers head was long and white, With love and truth his brow seemed bright; He told me what he would not tell For hope of heaven or fear of hell; And I lay listening in such pride! And, soon as he had left my side, Tripped to the church by morning-light To save his soul in his despite. Wordsworth’s and Browning’s work are similar in some ways but different in most ways. The main difference of their works is the genre itself. Wordsworth is employing lyrical dialogue in his poems in which he can be one of the persons in the dialogue. He is very effective in showing the beauty of what can be seen due to fact that his poetry are all about those he had highest regard and those he got involve with. His works tell truths of what is truly a happening and there is enthusiasm on it. He developed the prose poetry by employing dialogue in his poems. Browning is more focused on describing what is truly felt. His works dwell on emotions felt by a person in a certain situation. He developed the dramatic monologue which becomes the basis for modern criticism. In his works he makes use of personae to represent the person in the poem. These are actually fictional characters which speak for and express the emotion in the poem. He diverged from what is called tradition of poetry and tried to present his poem in a different view.

Value of the Biopsychosocial Model of Health

Value of the Biopsychosocial Model of Health Various approaches of rehabilitation based on scientific models are implemented to cope with disabilities, impairments, diseases (Lorenzo, M, 1999, p.1). Before the implementation of Biopsychosocial model, Biomedical model was traditionally practised and heavily used upon assessing patient. (Engel, 1977, p.130). Engel (1977, p.131) states that biomedical model illustrates the alteration of particular biochemical is commonly assessed in a specific diagnosis in relevant to the pattern of the disease. He also mentioned that additional concepts and frames of reference should be taken into account. Biopsychosocial model is said to be an improved model than biomedical model as it is a way of examining patients at the two important interlinked systems: mind-body connection. (Engel, 1977, p.132). This model was proposed by psychiatrist George Engel in a 1977 article in Science. This biopsychosocial model treats patients from biological, psychological and sociological aspects of body (Lakhan, 2006). Unlike biomedical model, psychological and sociological was not being emphasised as it solely examine the biological aspect (Erskine et al, 2003, p.173). The most obvious dissimilarity of Biopsychosocial model than Biomedical model is that Biopsychosocial model encourages patients active participation whilst Biomedical model is not much a model which promotes patient-centred care in terms of appreciating the individual needs and right of patients, understanding patients illness and health care experiences, and embracing them within effective relationships which enable patients to participate in clinical reasoning more (Ersser, 2008, p.68). Biopsychosocial model approach was used during a clinical placement; Mdm. C went for her first treatment in physiotherapy department after being referred case from an orthopaedics doctor to a physiotherapist. Mdm. C is a 56 years old housewife who is diagnosed with shoulder osteoarthritis. Shoulder osteoarthritis typically affects patients over 50 years old and it is more common in patients who have a history of prior shoulder injury as well as genetic predisposition (Cluett, 2009). Mdm. C was having language barrier with the physiotherapist responsible, Mr. S as she is incompetent in speaking English and Malay. Immediately, Mr. S finds another assistant who is able to communicate to her in Mandarin (Chinese). Despite the barrier faced, Mdm. C was greeted nicely by the Mr. S. Based on the physicians report, Mdm. Cs condition fulfilled the symptoms of shoulder osteoarthritis: inflammation and degeneration of cartilage, pain with activities, limited range of motion, stiffness of the sh oulder, swelling of the joint, tenderness around the joint, and a feeling of grinding or catching within the joint (Cluett, 2009). Both objective and subjective assessment is carried out to initiate the treatment as well as to identify and confirm the biological aspects. (Petty, 2004) While assessing Mdm. C subjectively, Mr. S communicates with Mdm. C whole-heartedly, questioning her about her background, her career, social life, daily habitual routines. Petty and Moore (2007, p. 130) states that this would ease the physiotherapist to investigate more about the initial cause of the deformity as well as to treat her effectively in achieving the short-term and permanent goal in rehabilitation. Physiotherapist practised active listening while listen with heart of compassion, patience and without any judgmental view. Physiotherapist should also choose words carefully and meaningfully without stepping into patients borderline by using open-ended questions to search for information until full understanding is achieved. Sensitive verbal and non-verbal communication is witnessed throughout the session (Petty and Moore, 2007, p.130). Physiotherapists attempt to enquire more about Mdm. C is successful as Mdm. C became more comfortable in exposing and describing more about her complains of pain. This indirectly allows the physiotherapist to gather more information for a better rehabilitation outcome at ease. Engel (1977, p.130) states that more information needs to be gathered during consultation as physiotherapists need to find out about the patients biological signs, psychological state, their feelings and beliefs about the illness, and social factors such as their relationship with families and larger community. Thus, the interview process acts as a mean for the patient to give as much information as possible not solely based on physical symptoms, but how the illness affects the patient. (Engel, 1977, p.130) Physiotherapist started the objective assessment with the examination of posture of Mdm. C in sitting and standing, noting the posture of the shoulders, head and neck, thoracic spine and upper limbs. Physiotherapist notes bony and soft tissue contours around the region. He checked the alignment of the head of humerus with the acromion as this can give clues about the possible mechanical insufficiencies. Mr. S pinch-grips the anterior and posterior aspects of the humerus, passively corrects any asymmetry to determine its relevance to the Mdm. Cs problem (Petty, 2006, p. 212). Objective assessments are accompanied by other tests and after all been carried out, Mr. S had drafted out the treatment plan for Mdm. C. Mr. S then carefully and slowly explained the treatment to Mdm. C and set a short-term goal for her as it would not be a burden for Mdm. C in short duration. Mdm. C also benefits from getting a better idea of her conditions, treatment alternatives, and expected improvements. Sullivan (2007, p.11) states that anticipated goal and expected outcome can address in predicted change in overall health, risk reduction, and prevention and optimization of patient satisfaction. He also states that this would further encourage faster recovery. Mr. S then applied hot packs on Mdm. Cs shoulder as heat helps to prepare the tissues for stretching and should be performed prior to any exercise sessions (Anderson, 2009). Time duration for 10-15 minutes are used for the treatment and several layering were used to wrap to hot pack to avoid burning of skin. Thermo therapy is believed to relax muscle tightness and to relief pain, reduce muscle spasm, and increases blood circulation (Inverarity, 2005). Mr. S then teaches Mdm. C simple exercises to facilitate her restricted movements. Before starting the treatment, Mr. S demonstrated the exercise slowly and gave short, clear and easy-to-understand instructions and explanations about the treatment without using scientific jargons and labels to enhance the understanding of Mdm. C as wells as to minimize the emotional distress (O Sullivan and Precin, 2007, p.56). This consider patients empowerment into account as physiotherapist informed and explained the treatment options to patients before commencing the exercise onto patient herself. The exercises given are: finger walk, towel stretch, and armpit stretch. The goal of these exercises is to stretch the shoulder to the point of tension without pain (Anderson, 2009). Mr. S monitored Mdm. Cs psychological aspects properly by observing Mdm. Cs facial expression and body language. Facial expressions act as an indicator of patients psychological affection(Petty, 2004). It would somehow affect the quality of exercises performed by patient. By observing patients facial expression, it tells physiotherapist how they are feeling while doing exercises and whether they are comfortable doing it or not (Petty, 2004). For instance, if Mdm. C feels like giving up due to fatigue and disappointment doing exercises, Mr. S would act as a motivator to motivate her to continue her efforts by encouraging and supportive words like, Dont stop, youre almost there, Keep going, youre doing very well, You can do it, its easy, Hang in there, just a while more, Youre doing very good, come lets finish it together, this indirectly would comfort the patients psychological discomforts and motivate her to be on the right track. Mr. S enquired again, if Mdm. C is comfortable with t he given exercises to ensure that Mdm. C knows what she is doing and why is she feeling this way, and how does she cope with it if she feels like giving up due to tiredness. These covered the psychological aspects (Petty and Moore, 2007, p. 131). Though Mdm. C came alone for this treatment, she was encouraged by both Mr. S and his assistant who are competent in Mandarin throughout the session. Thus, Mdm. C knows that she is not doing it alone. When the treatment session is over, Mr. S gave Mdm. C few sheets of paper containing the exercises she did earlier. Mr. S contacted Mdm. Cs nearest kin, her daughter to stress the importance of home exercises and to ensure that Mdm. C constantly does that at home, as well as to encourage the family members to participate in the exercises in helping Mdm. C to improve her muscle strength and relieve the symptoms. Mr. S educates the family members about precaution and safety at home. Mr. S strongly encouraged family members to accompany Mdm. C for her next scheduled treatment so to overcome the language barrier and to make the family involved. These cover the sociological aspects of treatment. Sullivan, (2007, p. 52) states that Social support helps the increased of self-esteem, adjusting and adapting oneself with disability. Biopsychosocial model takes into consideration of patients involvement in treatment, patients needs, and patients relationship with clinician during a clinical practise as this model comprises the biological, psychological, sociological aspects of a patient. To conclude, biopsychosocial model is practical, applicable, and agreeable as it brings enormous improvements on patients condition. (1497 words)

Comparing and Contrasting Relationships in Their Eyes Were Watching God

Comparing and Contrasting Relationships in Hurston’s Novels, Their Eyes Were Watching God and Seraph on the Suwanee In Their Eyes Were Watching God and Seraph on the Suwanee, Zora Neale Hurston creates two protagonists, Janie and Arvay, and depicts their rich relationships with Tea Cake and Jim, respectively. This brief paper compares these two women and their interaction with their husbands. Contrasting the similarities of these relationships helps underscore deeper themes that Hurston draws from two ostensibly different women. Tea Cake and Jim bear substantial resemblance to each other. They both carry a rather unsavory reputation around their towns, they both woo their new wives aggressively; they even take care of their women with occasional recourse to illegal improprieties such as liquor distilling and gambling (although they tend to spend their profits quite differently). Both men reduce to child-like behavior in key moments of affection with their wives; Tea Cake favors having his head in Janie’s lap, while Jim prefers his head resting on Arvay’s breast. Perhaps most crucially, both men exhibit communication and behavior that make their wives frantic with jealousy and fear. Jim, in his teasing of Arvay, and Tea Cake in his long absences, especially right after his marriage to Janie in Jacksonville, make their respective wives boil over with internal anguish. Janie and Arvay respond to their men in similar ways as well. Both women swing from extremes of doubt and distrust to passionate, all-encompassing love for their husbands. Moreover, both women reconfigure themselves to adjust to the man’s world, as when Janie moves to the Everglades with Tea Cake, and when Arvay goes out to sea with Jim on his fishing b... ...her silent thoughts and how they pulled her away from her love for Logan and Jody, now those same silent thoughts preserve Tea Cake for her in perpetuity. And in Seraph on the Suwanee, Jim’s departure allows Arvay to realize the chasm between her and her past, and in so doing, realize that her struggles portray a woman destined to be a caregiver. For both Janie and Arvay, inner turmoil is quelled into a role that reconciles both themselves and their relationship with their men. And, perhaps most remarkably, this idealization of their partners persists despite – indeed, is even enhanced by – the fact that both women see their former love interests, those who came before Tea Cake and Jim, as now standing on cracked or even shattered pedestals. Both Janie and Arvay in the end take comfort in their new-found roles and those men who best compel them to adopt these roles.

Othello Questions Essay

ACT I 1. While Shakespeare presents the world of Venice as a place of civilization, is slow turns into a place of un-civilization and disputes. For example, Roderigo and Iago wake up Brabantio and tell him that there are thieves in his house. In reply, Brabantio says â€Å"This is Venice. My house is not a grange.† This shows how Venice is not usually a place with interrupting events. . Shakespeare also shows how Venice is slowing becoming corrupt. This is demonstrated when Desdemona elopes with Othello. Brabantio orders a search to get Othello. When Othello tells the Duke Brabantio accusation are false another search is put in place for Desdemona for questioning. Desdemona tells her dad that she is married to the Moor, Othello. Brabantio then disowns Desdemona, his daughter which is a sign of Venice becoming un-civilized. This is showing un-civilization because in Venice it is highly unlikely for a white women to marry a black man and for a women to disobey her father’s orde rs. Since Shakespeare does not go into much detail about Othello’s background, it seems as if his homeland is unimportant. Othello is referred to as a Moor which is a common name given to those who are from Africa. 2. Since Shakespeare starts the play with Roderigo and Iago, it to give the audience important information the plot. They both contribute to the exposition because they help the audience understand the situation through Iago’s and Roderigo’s point of view. Iago is a very intelligent, manipulative man and Roderigo is a foolish, gullible and stupid. Iago relationship with Roderigo is that he is just using him Roderigo is devastated to learn that Desdemona had eloped with Othello, so Iago uses this too his advantage. In act 1 scene 3 Roderigo says, â€Å"What should I do? / I confess it is my shame to be so fond, but it is not in my virtue to amend it.† This quote shows Roderigo talking to Iago about his love for Desdemona. 3. Since Iago expected to be promoted to lieutenant, and Michael Cassio got the spot instead, Iago plotted his revenge against both Cassio and Othello. Iago was close with Othello at the beginning and throughout the play continues to pretend to be friends with him but is not. This shows how Iago is not very trustful. The following quote expresses Iago’s angry towards the situation. â€Å"Off-capped to him, and by the faith of man I know my price, I am worth no worse a place. But he (as loving his own pride and  purposes) Evades them with a bombast circumstance Horribly stuffed with epithets of war, And in conclusion Nonsuits my mediators. For ‘Certes,’ says he, ‘I have already chose my officer.’ And what was he? Forsooth, a great arithmetician, One Michael Cassio, a Florentine.† The following quote shows how upset Iago is with Michael Cassio getting the promotion, and this is the reason why Iago is angry with Othello. 4. Since Othello is a black man from an unidentified part of Northern Africa, he is seen as an outsider in Venice. He was once enslaved and has gone on many harsh battles and journeys in many parts of the world. Yet, Othello has a tendency to try and find the best in people and he trusts many until it is proven that he should no longer have faith in them. Othello is well known to be a good general due to his past experience in war and he is respectful towards people even when they are not respectful to him. This can be seen in the following quote when Brabantio is very rude and disrespectful to Othello but he responds saying, â€Å"Hold your hands, Both of you of my inclining and the rest†¦Ã¢â‚¬  This shows how he is raining calm in a very heated conversation. When Othello speaks and interacts with other characters he is respectful because he is an outsider and does not feel comfortable as he would in his homeland. By marrying Desdemona Othello is able to feel less like an out sider in the community in Venice and Cyprus. 5. Since Desdemona was sneaky about her love for Othello her father, Brabantio did not know about Othello and Desdemona seeing each other. Brabantio is awakened late at night by Roderigo and Iago yelling at him that there is a thief in his house who has stolen his daughter, Desdemona. Brabantio and Roderigo have a discussion about how the Moor and Desdemona are seeing each other. The following quote shows the conversation with Roderigo and Brabantio talking about Desdemona and the Moor. â€Å"Brabantio: Raise all my kindred. –Are they married think you? Roderigo: Truly, I think they are.† Act I Scene I Page 19 Lines 187-190. The quote shows how Roderigo is informing Brabantio that his daughter, Desdemona and Othello are married. Brabantio believes that the Moor casted a spell upon Desdemona in order for Desdemona to fall in love with Othello. This shows that at the time women were expected to love a man that her father would approve of. The following quote is a conversation between Brabantio and Othello. The quotation shows how Brabantio believes Othello placed a spell upon Desdemona so that she would fall in love with him. â€Å"Damned as thou art,  thou hast enchanted her!† Act I Scene II Page 25 Line 83. The quote shows how upset Brabantio is at Othello because Othello and Desdemona are together. The following quotation reveals how Desdemona and Brabantio react toward each other about the marriage. â€Å"Desdemona: I am hitherto your daughter. But here’s my husband†¦. Brabantio: God be with you! I have done.† Act I Scene III Page 41 Lines 213- 219. Brabantio could not accept the fact that Desdemona is in love with Othello. The quote shows how Brabantio tells Desdemona that he is disowning her and how he wants nothing to do with Desdemona anymore. It is important that Desdemona and her father separate at this time in the play because it allows Iago to put his plan of savage into action. Desdemona has no family anymore and now she is going to travel with Othello to a place of warfare. At this point in the play Desdemona is very vulnerable. 6. Othello’s and Desdemona’s understanding of their love and relationship are not equivalent to one another. Othello believes their love was founded upon his valiancy and torturous past. Desdemona feels that she fell for his sincerity and strength, thus intriguing her and gaining her love. When Othello must explain his love for Desdemona in the presence of her father and the Venetian council he explains he wooed her through his chivalrous stories and he loved her for her sympathy and aww, not because of qualities she possessed. He explained â€Å"My story being done, she gave me for my pains a world of sighs†¦ she thanked me and bade me, if I had a friend that loved her, I should but teach him how to tell my story, and that would woo her. Upon this hint I spake. She loved me for the dangers I had passed, and I loved her that she did pity them† (Act 1. Sc. 3).   He in the end loved her for stroking his ego and she loved him for his bravery and heart, though he lacked in humbleness. Othello and Desdemona do not share a reciprocated love for one another. 7. Because Iago and Othello are contrasting characters, their manners of speaking are very different. Othello’s character is very respectful to others. Even when he is being insulted, he remains calm. He is also very truthful and open with his words. On the other hand, Iago is duplicitous throughout Act 1. He often has double meanings behind his words. For example, he tells Brabantio, â€Å"An old black ram/ Is tupping your white ewe†. This is a crude way of telling Brabantio that Othello has married Desdemona. This shows the difference between the characters. It is also significant since Othello’s trusting nature is what  Iago will use to betray him. 8. When the Duke of Venice tells Brabantio, â€Å"Your son in law is more fair than black.† this shows that not everyone in Venice shares Brabantio’s views on Othello. The Duke wants Brabantio to look beneath his son in laws skin and see that he is fair and deserves to be respected. He Senators and the Duke admire Othello and that is why the Duke defended Othello when Brabantio accused his of using â€Å"witchcraft† on Desdemona. The Duke then responded and gave Othello the compliment that he is â€Å"fair†. This word is troubling because it makes people think about Othello’s race and how he is different from everyone else. Even the color of his skin has not prevented him from achieving high rank in the Venetian society. These achievements have earned Othello respect from the people around him. By reading the play Othello you are able to depict the Venetian society in depth. 9. Since Brarbantio’s says to Othello â€Å"She has deceived her father, and may thee,† it shows how Desdemona might betray Othello. This is very important because later in the play Othello thinks that Desdemona does betray him. The play show that women are viewed in society as being loose, and untrust worthy. 10. Since Othello is more of an outside he would fit in with the Turkish society. It is very important that Othello protects Cyprus because it communicates to the audience that the Venetian and the religion is superior, showing that Othello has much power. Act II 1. In Act 2 Shakespeare represents Cyprus as the land of partying and recklessness. This furthers the action of the play because it gives Iago a lead in his plan.Cyprus is described very highly by Othello in the following quote â€Å"How does my old acquaintance of this isle?—Honey, you shall be well desired in Cyprus, I have found great love amongst them. O my sweet†¦,† Shakespeare uses Cyprus because it’s the perfect place to help Iago get revenge on Othello without any suspicions being raised. In Cyprus everyone lets is excited that they do not have to fight in the war and have a lot of celebrations. This furthers the action because Iago gets Cassio drunk and Cassio’s lieutenancy gets stripped, the following quote shows Cassio upset that he got his lieutenancy taken away. â€Å"Reputation, reputation, Reputation! O, I have lost my reputation!† This builds suspense because the audience is starting to see how Iagos plan is slowly falling into place. 2. Since Cassio is handsome, trusting and brave he is a very unique character. He helped confort Desdemona when Othello was still at sea. The following quote showings how respectful, kind, and caring Cassio is to Desdemona, â€Å"Hail to thee, Lady and the grace of heaven†¦ He is not yet arrived, nor know I aught but that he’s well and will be shortly here.† This quote shows Cassios respect towards Desdemona and him calming her down about Othello not being present. 3. Cassio is manipulated by Iago because Iago is planning to ruin Cassio so he can get the place as lieutenant. Iago learns about Cassio’s weaknesses and uses them against him. This includes his drinking problem, which led to Cassio getting fired by Othello. Also Cassio’s reputation for with women sets the basis for how Iago convinced Othello that Cassio was interested in Desdemona. Iago knows that by getting Othello to think Desdemona is cheating on him, that he will become extremely distraught. Iago uses Brabantio’s words to sway Othello’s thoughts throughout the text. In the beginning, Brabantio said â€Å"Look to her, Moor, if thou hast eyes to see: She has deceived her father, and may thee.† Which means, she deceived me and she will most likely do it to you too. 4. As the audience reads through Act II Iago’s plan begins to unfold. It is also revealed to the audience that Iago has a way of identifying other characters weaknesses and then manipulating these weaknesses to his advantage. As Iago begins to share his plans and ideas the audience receives more insight into the plot of the story and what Iago has in mind next. Iago deceives people by always making them believe that he is keeping their best interest in mind. By having the other characters believe that he is â€Å"honest Iago,† as the characters come to call him, he is then able to persuade them to believe something or do something else that will help Iago with his plan. Iago is revealed to be a sly character with only his own interests in mind. A quote from Othello when Iago is speaking falsely is, â€Å"I had rather have this tongue cut from my mouth/ Than it should do offense to Micheal Cassio.† (Othello, Verses 236-237) This quote shows the readers how Iago sa ys one thing to other characters, when the audience knows that he wants to get rid of Micheal Cassio. Even though the audience knows that Iago is speaking falsely, the other characters in the play still have no suspicion about Iago’s plan of revenge. This dialogue is one way that we learn more  about Iago in the second act. 5. Since Cassio and Iago are foils, the language they use to speak to others are very different. Cassio speaks more respectfully while Iago is rude and wit. For example the following quote shows how Cassio is speaking very highly and respectful when talking to Desdemona. â€Å"Hail to thee, lady, and the grace of heaven, before, behind thee, and on every hand Enwheel thee round.† (Act 2 Scene 1 Page 65 Lines 94-96) In contrast, Iago is very disrespectful to women especially to his wife, Emilia. The following quote shows Iago yelling at his wife to be quite. â€Å"Go to! Charm your tounge†¦.What, are you mad? I charge you to get home.† (Act 5 Scene 2 Page 251 Lines 222 and 231) The quote shows how Iago’s dictions is far more ill-mannered in contrast to Cassio’s language. Act III 1. In the beginning of Act 3, Scene 3 Othello is madly in love with Desdemona, but towards the end he becomes full of jealousy. Othello believes that Desdemona has had an affair with his once loyal lieutenant, Cassio. The reason he trust in such lies is because his good friend, Iago, has convinced Othello of Desdemona’s dishonesty. Iago persuades Othello by feeding him false grotesque images of Cassio and Desdemona and Gplants Desdemona’s handkerchief, a gift from Othello, in Cassio’s room. â€Å"I know not that; but such a handkerchief- / I am sure it was your wife’s – did today / See Cassio wipe his beard with† (Act 3, Sc. 3). What is most surprising is Othello, who quickly believes Iago’s statements. Othello, obviously not completely trusting Desdemona to be faithful, was most likely led to this paranoia after Desdemona’s father, Brabantio, planted the thought of her betraying Othello after Brabantio was betrayed by Desdemona himself. With this proof, Othello has no option but to believe Iago and his persuasive and duplicitous dialogue. 2. Emilia develops a close relationship with Desdemona. Emilia and Desdemona bond over husband trouble: Emilia’s bitter take on her married life with Iago contrasts with Desdemona’s marriage to Othello. Emilia is honest even though she caused the mess with Desdemona murder, but she redeems herself, or at least gives a good shot at trying. Emilia who discovers the truth about Iago’s plotting and tries to reveal it. Emilia’s relationship with Iago is not strong, and Iago uses Emilia as his tool. Iago  has no ability to love someone or something. This quote is proof that her husband uses her, â€Å"The ills we do, their ills (husbands’) instruct us so?†(Act 3) 3. In the play Othello, Shakespeare uses a love token, Desdemona’s handkerchief to symbolize a relationship between two people. Othello gave Desdemona a handkerchief, as a gift that represented their marriage bond itself. One problem that the handkerchief causes is that it was handled by almost everyone in the play. The main thing the handkerchief symbolizes is Desdemona’s fidelity for Othello. When Cassio gets ahold of the handkerchief, Othello feels as though Desdemona has been unfaithful to him. When Desdemona is trying to ease Othello’s headache she drops her handkerchief. Emilia picks it up and gives it to Iago, her husband so she could get on his good side. â€Å"I am glad I have found this napkin. This was her first remembrance from the Moor. My wayward husband hath a hundred times wooed me to steal it. But she so loves the token.† (Act 3 Scene 3 Lines 334 to 337) Iago then tells Othello that Cassio has wiped his beard with Desdemona’s handke rchief and that’s when they decide to kill both Desdemona and Cassio. Desdemona continues to look for her lost handkerchief and when Othello asks for it, she gets even more nervous. With Desdemona’s handkerchief it made all of Iago’s plan to come togethe Othello Questions Act IV 1. The handkerchief of all things plays a key and important role in act four because it is what leads Othello to believe that Cassio has slept with Desdemona. â€Å"Handkerchief – confession- handkerchief – to confess and be hanged for his labor† (Act 4 Scene 1) this quote by Othello explains his thoughts towards Cassio and Desdemona seeing each other. Othello becomes very upset because the handkerchief was the first gift from Othello to Desdemona to represent his love for her. 2. Othello’s character is changing by in the beginning of the play Othello begins as a noble guy who is a respected war hero, and loving husband. Towards the end of the play Othello becomes violent and insanely jealous husband who murders his own wife after Iago convinces him that Desdemona has been unfaithful. The following quote shows Desdemona being slapped by Othello â€Å"Othello: I am glad to see you mad. Desdemona: Why, sweet Othello! Othello: [Striking her] Devil!† This shows  how Othello slowly becomes less respectful towards Desdemona which is how his character is changing. 3. The effect when Othello slapped his wife Desdemona in public was that he was becoming an insane man and that he wasn’t fit to be the general anymore. Also the slap brought humiliation upon Othello because no one thought he would slap his wife that he was so loving and gentle towards. The following quote shows Lodovico speaking with Iago about Othellos behavior. â€Å"Is this the noble Moor whom our full senate Call all in all sufficient? Is this the nature Whom passion could not shake? Whose solid virtue The shot of accident nor dart of chance Could neither graze nor pierce?† When people saw this, they began to question Othello’s judgment. This reveals the change in character within Othello. He went from a loving, nice leader unto an angry, abusive man. 4. The contrasting characters; Desdemona and Emilia, form an interesting and important relationship in the play Othello. Desdemona is very ‘sheltered’ from the ways of the world and Emilia is very ‘down to earth’ and ‘experienced’. They have very different views on marriage Emilia states she would commit adultery if it gained her husband. The following quote shows their conversation. â€Å"Emilia: In troth, I think I should, and undo ’t when I had done. Marry, I would not do such a thing for a joint-ring, nor for measures of lawn, nor for gowns, petticoats, nor caps, nor any petty exhibition. But for the whole world? Why, who would not make her husband a cuckold to make him a monarch? I should venture purgatory for ’t. Desdemona: Beshrew me, if I would do such a wrong for the whole world† .Desdemona states that she is loyal to her husband. One thing that is similar about these marriages is the lack of trust and patience reve al the fragileness of the marriage. This scene shows the women’s private life and how they are not always the way the display themselves. Othello Questions Act V 1. Othello kills Desdemona because he was convinced by Iago that she was cheating on him with Cassio. He doesn’t want to have to kill her because she is the love of his life, but Othello feels so betrayed, upset, and angry that he thinks it’s the best solution. The audience knows that Desdemona was always completely loyal to Othello and never had a relationship with Cassio.  Othello thinks that he is solving the problem but really he is making a huge mistake. He is so distraught over having murdered her, that he kills himself as well. â€Å"Yet I’ll not shed her blood; Nor scar that whiter skin of hers than snow, And smooth as monumental alabaster. Yet she must die, else she’ll betray more men. Put out the light, and then put out the light: If I quench thee, thou flaming minister, I can again thy former light restore, Should I repent me: but once put out thy light, Thou cunning’st pattern of excelling nature, I know not where is that Promethean h eat That can thy light relume. When I have pluck’d the rose, I cannot give it vital growth again. It must needs wither: I’ll smell it on the tree† The quote shows how he was struggling with choosing if he should kill her or not to. 2. After the death of Desdemona, Emilia begins to figure out Iago’s plan. Once Emilia is able to figure it while talking with, she begans to realize her husband’s true self. Before Iago was not very pleasant toward his wife, Emilia, but she never said anything about it because women were supposed to be obedient Emilia starts to speak out because she is upset of Desdemona’s murder. Emilia says, â€Å"Do thy worst.† To Othello as he pulls out his sword on her even though she is unarmed but he is mad because she is defying a man and that was not allowed during that time period. Women were expected to be compliant, which is shown to later when Emilia says, â€Å"I will not charm my tongue, I am bound to speak.† This quote shows how women were not supposed to give their input into things. Because Emilia finally stood up for herself and others, consequently she was killed by Iago. 3. Before Othello kills himself he gives a long speech about how he should be remembered. For example he wants to be remembered as a person who loves strongly but not wisely. After he stabs himself he kisses Desdemona because before he killed her he kissed her and wants to do the same for himself. The following quotation shows this. â€Å"I kissed thee ere I killed thee. No way but this, Killing myself, to die upon a kiss.† Act V Scene II Page 265 Lines 420-421. He does confess to killing Desdemona and regrets it greatly. The Play as a whole 1. When Iago is describing his vengeful plan against Othello to his loyal companion, Roderigo, he explains that he is not what he will disguise  himself to be. The quote â€Å"I am not what I am† (Act 1, Sc. 1) told by Iago could also apply to more than one of the characters. Desdemona, portrayed by her father as a timid and naà ¯ve child, is the one who betrays his trust by eloping with â€Å"The Moor†, Othello. â€Å"Your daughter, if you have not given her leave, / I say again, hath made a gross revolt, / Tying her duty, beauty, wit, and fortunes / In an extravagant and wheeling stranger† (Act 1, Sc. 1). Therefore, in the text, Iago is not the only character who pretends to be something they are not in order to trick someone else and disguise their underlying plans. 2. Since Iago destroyed Othello’s life very cruelly, it is likely that he had several motives for his deception. In the beginning, Iago states that he felt betrayed that Othello had promoted Cassio to the position he felt he deserved. This was probably a large factor of his deception, since Cassio was targeted for murder in Iago’s plot. Another motive was that there were rumors about Othello sleeping with Iago’s wife, Emilia. Iago also causes Desdemona’s death, saying, â€Å"Nothing can or shall content my soul / Till I am evened with him, wife for wife†. In the end, jealousy of Othello seems to be Iago’s motive. He is jealous of Cassio’s promotion, jealous of Othello’s beautiful wife and feels betrayed by Othello. 3. During this play Iago is able to manipulate Othello threw his weaknesses which are self doubt, his race and that he is madly in love with Desdemona. Iago uses all of the characters weaknesses to catapult their downfall. Mostly, he wants Othello to pay for what he did by making Cassio lieutenant and not him. From the beginning of the play, Iago proclaimed that he would make Othello pay by saying, â€Å"I am not what I am.† (Act 1 Scene 1 Line 71) Othello is prone to jealously is afraid that Desdemona will leave him for a Venetian man. This also plays into his race because he always feels like an outsider throughout the whole play. One reason Othello was manipulated so easily was because of all the â€Å"proof† Iago was giving him. When Iago was telling him this information, Othello should have gone to figure out if it was true; if Othello would have noticed Iago was being dishonest. Desdemona ended up paying for Othello gullibility when Othello smothered her with a pi llow. Racial tension is heavy during the play because they really want to emphasize that Othello is an outsider and doesn’t belong in Venice. The only reason Othello has power is because he is the General, but even though he is the general he still is modest. When  talking to the Duke in Act 1 Scene 3 he starts off explaining how he is a bad poet but then says this elaborate and long explanation about his and Desdemona’s love. From the beginning to the end Iago was able to manipulate everyone because they were all caught up in somebody or something else. 4. Since Emilia and Desdemona had different viewpoints on love, the play does not suggest whether or not Emilia or Desdemona is correct. Emilia and Iago’s relationship was not very loving, also Emilia said she would cheat on her husband which indirectly states she is not loyal to him. In contrast, Desdemona is very loyal and loving towards Othello, even after she was done wrong by him she was still loyal. This can be shown in the following quote when Desdemona is dying after Othello kills her â€Å"Desdemona: A guiltless death I die. Emilia: O, who hath done this deed? Desdemona: Nobody, I myself.† This shows how she still is remaining loyal to Othello by not saying that he killed her. 5. Othello’s heroic and military proficiency allow him partial acceptance into Venetian society. This acceptance is temporary because he doesn’t feel that he has been embraced by Venetian Society, he is both an insider and an outsider. On one hand, he is a Christian and experienced military leader, commanding respect from the Duke, and many Venetian citizens. On the other hand, being a black Moor and a foreigner in Venice also subjects Othello to some racism epically by Brabantio and Iago. The following quote shows Iago describing Othello and Desdemona’s relationship â€Å"Even now, now, very now, an old black ram ewe. Arise, arise; devil will make a grandsire of you. Is tupping your white Awake the snorting citizens with the bell, Arise I say!† The quote shows a racial slur toward Othello. 6. The addition of Bianca, causes her to be more of a women stereotype. Cassio does not mistreat his wife unlike Iago and Othello. Bianca is not seen as much throughout the play. On the other hand, Desdemona is a brave and beautiful woman who stood up to her father, and traveled with her husband. Desdemona and Othello have a very strong relationship at the beginning of the play. Othello starts out very respectful towards his wife, but slowly is rude to her. Emilia and Iago are married, but Iago does not respect Emilia and he treats her badly, he says â€Å"To have a foolish wife.† He does not have any respect for her. Iago says rude things to Emilia and all  she does is try and please him. All three of the women have one thing in common, they all end up without a husband at the end of the play. 7. The play does reinforce racial stereotypes. For example, Othello is addressed as a moor, making it seem as though he isn’t at the same level as them in the social hierarchy. The following quote is an example of when Othello is referred to as the Moor. â€Å"Is this the noble Moor?† Even though he is called the noble Moor is he not address by name, which makes him seem more of an outsider. 8. I believe that we should admire Desdemona for her love. She did everything she could to make Othello happy. It is very unfortunate that Iago was able to manipulate Othello into thinking he had to kill her for something that she didn’t do. â€Å"I kiss’d thee ere I kill’d thee: no way but this; 359 Killing myself, to die upon a kiss.† 9. Shakespeare has placed a very small amount of action in the play and instead placed a large amount of dialogue. Shakespeare’s reasoning behind this use of dialogue is to affect the reader by allowing them to get to know the characters more. This allows the characters to be characterized by what they say and by what other characters say about them. The readers then go through and are preserved through the eyes of others, mostly Iago, and this allows Shakespeare to help and give certain information to the audience. Also, the reader learns a lot about the characters through dialogue and dialogue helps the reader to feel more involved in the play. When Iago says, â€Å"I am not what I am,† the audience is able to feel more involved and to get more information regarding Iago’s characterization than in other parts of the play. 10. Because Iago is trying to get revenge on Othello for not being promoted, the main theme of the text would be jealousy. Iago is jealous of Cassio that he got the promotion to become lieutenant. The following quote shows how Iago is upset that he was not promoted. â€Å"I know my price, I am worth no worse a place†¦ say he, ‘I have already chose my officer.’ And what was he? Forsooth, a great arithmetician one Michael Cassio†¦Ã¢â‚¬  (Act 1 Scene 1 Page 7 Lines 12-21) The quote shows how jealous Iago is that Othello chose Michael Cassio to be lieutenant. Another way Othello by William Shakespeare, shows jealousy is when Othello kills his wife because he thinks that she is cheating on him. It seems that Desdemona is cheating on Othello with Cassio, but she is not. Sadly Othello does not know that it is Iago’s plan to get revenge on Othello. Consequently, Othello kills his own wife. The following quote  shows when Othello confronts his wife about seei ng Cassio, also the quote shows Othello killing his wife. â€Å"By heaven, I saw my handkerchief in ’s hand. O perjured woman, thou dost stone my heart, (Act 5 Scene 2 Page 241 Lines 77-78) ‘Twas I that killed her.† (Act 5 Scene 2 Page 247 Line 160) This quote shows how Othello was jealous that Desdemona was with other guys. Since the plot revolves around jealousy it is appropriate that the main theme in this text would be jealously.
