Physician career - Research Paper Example This paper investigates the academic requirements, career outlook, and potential income of studying medicine as a career in addition to talents and personal attributes necessary to succeed as a physician. In United States, all medical practitioners with a professional degree in medicine are regarded as physicians. UBLS (2010) classified physicians in two different categories, including Medical Doctor (MD) or allopathic physicians and Doctor of Osteopathic Medicine (DO). Both classes of doctors apply all acceptable practices of treating patients, including prescription of drugs and carrying surgical operations. However, doctors of osteopathic medicine emphasize mostly on preventive medicine, muscular skeletal system of the body and holistic care of patients. Medical doctors are mainly the primary medical care providers and they are normally specialized in all medical specialties (UBLS 2010). According to OES (2011) about 50% of medical doctors practice general medicine, pediatrics, an d internal medicine. Physicians could be specialized in one or more areas of medical specialization, including anesthesiology, general pediatrics, general internal medicine, psychiatry, obstetrics and gynecology in addition to general medicine among others. The requirements for becoming a physician differ depending on the final area of medical specialization in the United States. However, physicians are normally required to complete a four-year undergraduate degree program and then proceed to a medical school where they spend another four years. This is followed by a compulsory three to seven years in resident training after which they become eligible for being licensed as doctors. In this regard, medical doctors in the United States are required to complete two degrees and specified duration of clinical residence. According to AMA (2009), both of these degrees involve general course work while during the residency; the aspiring doctor chooses his or her preferred specialty. A four- year undergraduate degree marks the beginning of physician training program in the United States. The undergraduate program involves coursework in sciences, math and English. The first degree prepares the student for entry into the medical school and students must attain specific grades to qualify. Aspiring medical students have the freedom to choose any undergraduate degree, but many of them enroll in programs with heavy emphasis on chemistry and biological sciences. However, undergraduate training differs from one institution to another. Some tertiary institutions offer pre-medical programs that include mandatory classes for medical school in addition to preparing students to pass Medical College Admission Test (MCAT) (AMA 2009). After successful completion of the undergraduate degree, aspiring medical students are required to take Medical College Admission Test (MCAT). The test compromises of multiple choice questions that examines the student‘s knowledge on physical scienc e, critical thinking, biology and communication skills. The test is computerized and it takes a maximum of five hours. The performance on this test and undergraduate degree play major role in securing admission in medical school (AMA 2009). Students who score high marks in the test and have good undergraduate degrees are almost assured of admission into the medical

Internet marketing - Assignment Example The buy-side and sell-side of e-commerce is very important in organizational marketing. Internet marketing directly deals with the sell-side of the whole transaction (Chaffey, 2004). There are multiple drivers to the concept of internet marketing. In the course of following discussion, the tutor will be analyzing the key aspects of internet marketing, using the case of e-bay company as an example. Highlighting on the identified factors, the concept of internet marketing mix will be explained. Further, an attempt to draw comparisons on the e-marketing tools or e-tool practices and examine the chain of order processing, with the help of the case study will be covered in the following discourse. One of the world’s largest and most popular online marketplaces, eBay, enables its customers the unique facility to trade in millions of items each day. This company was formed by Pierre Omidyar, with a business objective of achieving excellence of being recognized as a most valuable internet retailer (Gopalkrishnan and Gupta, 2007). One consistent stride was to keep improving company’s performance, maintain stable growth and create a fun-loving efficient market place. This breakthrough and strategic management approach offers a competitive edge over its competitors and sustainable growth to the organization. EBay was launched from Omidyar’s home in the mid-1995.s with a concept of creating an Internet marketplace. Ever-since its formation, eBay was well received by its users, who expressed their liking through hits. Keeping his hopes and aspirations high, eBay went on to become a public enterprise in the year of 1998 at a value of $18 a share (Griffith, 2007). In 1999, the trade value rose to a figure of b$282 per share. By successfully beating its competitor Amazon.com, eBay established itself as the world’s most valuable Internet retailer (Lucking†Reiley et al., 2007). By definition, the concept of e-business is the transformation of

Factors Affecting Millennium Development Goals Progress

Factors Affecting Millennium Development Goals Progress Abstract Water and sanitation is a global canker facing the most world population especially in Africa. Policy makers anticipate 80 billion Euros are needed every year to provide basic sanitation to the rural poor to ease poverty, therefore the need to get an in depth view of sanitation lagging behind is paramount. This paper aims to assess the factors causing the slow of progress in achieving the Millennium Development Goals(MDG) in low-income countries. The pace are due to inadequate infrastructure systems, skilled labour constraints, insufficient political will and growth of population. It will review current studies in the sector and analyse various constraints that jeopardise the achievement of the sanitation development precisely Ghana. In this review article, published journals, reports, conferences are observed. As a results of the above review factors that is hampering MDG sanitation for Goal 7, it was concluded that policy framework should be put in place whereas government and dono r organisations enforced and invest more in sanitation. The research should assist in the development process in an optimised way of addressing water and sanitation issues and allow better understanding of environmental differing that is triggering the success of MDGs. Keywords Millennium Development Goals ; Ghana; Factors affecting water and sanitation development 1. INTRODUCTION AND BACKGROUND Currently, 2.6 billion people in the world has no access to adequate sanitation(Marion W.jenkins ,2007) and 1.1 billion lack safe drinking water . (Water Aid,2008)representing to two fifth of the world population, leading up to range of diseases like cholera, a devastating cause of child deaths(Marion W. 2007). In Asia 675 million people are without improved drinking water sources and in sub-Sahara Africa, only 36% has no access to basic sanitation (Christine L. And Richard D.2006).The ability of low-income countries to productively solicit external support to scale –up aid is the major confronting issue today. As vast number of international organisations on the verged to address the problem in developing world whiles envisaging the need for every humanity to have access to basic sanitation, Ghana as part of the sub Saharan Africa will not be able to achieve the MDGs (DFID,2006). UNICEF The World Summit on Sustainable Development(WSSD) in Johannesburg in 2002 adopted an international sanitation target to halve the number of people without access to basic sanitation by 2015.This target now transform its self for water supply in support of the Millennium Development Goal of ensuring environmental sustainability(WELL,2003). Considering figures above, indicates the progress and geographic areas of where water and sanitation has covered as of the year 2002.The enormity of the constraints comes with the acknowledgement that poor state of infrastructure impediments are the cause of not achieving the MDGs(refer to appendix2 ) because 50% of the population cannot access improved services serving as an issue(Antonio E.2005), (UN,2007).William Easterly,2008 argued that the MDG are unfair to Africa because MDGs are poorly and arbitrarily designed to measure progress against poverty and deprivation, and that their design makes Africa looks worse than it really was. Most importan tly, another article stated the need for external donors to increase funding although infrastructure systems is another challenging(hlsp, 2009).Contrary the (UNDP,2008) report reveal that lack of framework made monitory difficult to measure and therefore data availability in other cases was unpredictable for the reason been poor system of infrastructure in some countries for collecting appropriate statistics. Empirically, programmes in sanitation in developing countries has been fruitful and yielding results (Marion W. Jenkins and Beth Scott,2007) yet there is an overwhelming number of people who keep on installing latrines or toilet facilities in their homes without subsidy from donors to improved sanitation. Moreover, the global climate change that policy makers have been preaching, the impact in Africa where water crisis is escalating and water table been high especially in the region of Tamale where is terribly hard to drill a sunken borehole a get water even if there is then is possible it may contained 40% of salt(REVSODEP/SIMAVI,2003). Other studies have shown that climate change is a challenge to the success of the MDG(United Nations Economic and social council,2007). A number of studies have reported MDG trend progress of sanitation in Ghana as shown in (appendix1 and appendix 5) shows a series of attainable indicators how Ghana is progressing even though comments regarding poor infrastructure systems exist (Christine L. And Richard D.,2006) which tends to propel the success of sanitation projects in the developing nations . Similar findings have been made via (UN ,2006)department of economic and social affairs. However, most of these studies were based on different country orientations and gross domestic product(GDP) performance raised at the time the survey was made. As such, Aid scaling –up(Peter S.Heller,2005) to the overriding . International Journal on environment resource public health in Zambia 2006 found that lack of well staffed healt h care facilities, electricity, portable water, roads, adequate transportation and communication facilities contributed immensely to not meeting the sanitation target quiet apart from the political instability of other African region. This analysis is similar to less development of in local and national institutions in south Africa(Neville,G.2003) although south Africa is progressing well as compare to Ghana and others. The following Other objectives will enable us dig out further factors. To make a literature review of MDG in sanitation and evaluate current technology options used. Identify factors seen in other studies. To develop, discuss and analyse data. Make recommendations/strategy for promoting sanitation development. 1.2 Ghana The republic of Ghana is a country in west Africa with a population of about 22.1 million people(iicd,2007).The country was the first sub-saharan Africa country to obtain independence from colonial rules on the 6th of march 1957.Despite the country rich in natural resources such as cocoa, gold, timber, bauxite, salt and lately the discovered crude oil, the country is still in perennial sunk with water and sanitation diseases. After colonial rule the country is divided into 10 different regions which include, Northern region-Tamale, Bolgatanga, upper west region, Ashanti region, Volta region, Brong ahafo region, Central region, Eastern region, Greater Accra and western region(see appendix8) . In Ghana rural population who have access to safe water in 2005 stood at 54%, rural population with access to household latrine 25%, urban population with access to safe water 78% whiles 45% of urban citizens can boost of household latrine(WELL,2004). 2. Skilled labour constraints It has been observed that for the Millennium Development Goal to achieve the set target in the sector of water and sanitation the human resources are vital. Shortages of skilled persons (World bank report,2005), (Lancet,2004)affect the health systems as indicative to progress of the MDGs.Erica User in 2005 indicated that international migration is associated with the non achievement of the MDG which seems to be increasing alarming and no resourceful person to deliver sustained latrines. The general conception that the success of MDG 2015 will be met only when african government invest more in sanitation(Arne B. And Abebe S. 2006) than they do now can be in approperiate in some countries without the necessary manpower skill needed. Conventionally, it will also interest the international community to realiseing the poverty nature in developing countries are more than the recoarse (IWA,2008)and therefore should be examine in different perspective way, progress has been hampered by popul ation growth, unbattled HIV/AIDS, wide spread poverty.The view supported by working policy No.45 of (Goerge Essegbey et al 2007) who discovered that innovation in water and sanitation systems were made but was beyond the capacity of of the local people. Unlike in Kumasi a population of 19% of Ghana population census 2000 where technical drawings were made by a consultants for a contractor to implement the work and due to lack of skills required to execute the Ventilated improvement project with respect to the design specifications ,errors were degenerated due to the fact that local people incorporated bamboo sticks in the facility leading to unsuccessful work done. Comparing the situation in Asia to Ghana,(Ljiljana and Ram,2006) in 32nd WEDC international conference in Sri lanka vividly said institutional capacity building can been noticed as the most hindering factor for MDGs. Professional such as engineers who are knowlegeable, skillful and are suppose to assist Non governmental o rganisation and community based organisations in advocating and trainning the latter were seen non available. Again, sanitation projects were constructed in Nepal as shown in the figure3 below similarly described by (JMP ,2008)is a latrine constructed without a slab cover can be considered unimproved. The latrine was contracted to unskilled contractor without the trainee. Moreover, (Maguire,1990) arguable said Lack of knowledge of lower cost technologies and use of technologies in appropriate for developing countries was given in 1988 as one of the obstacles to decade success. 3. Political will Some studies have shown knowledgeablly that lack of political (appendix 11) williness contributed to the slow progress of water and sanitation development in the south(Trocaire,2005),(IWA,2006), (macho ventura,2008). In Ghana for example,Rural areas and small towns had benefited from cross-subsides on water made possible higher tariffs in larger urban areas. But in preparing for privatisation, the government has eliminated such subsidisation by separating out the more lucrative urban water services. This jeopardised the financial sustainability of rural services(UNDP,2007) policy research brief illustrated. On the other hand, this was been carried due to two or more reasons after the implementation of the scheme and as developing change comeby some policy of government will need to change in order not to cause future catastrophe in the long run. Although Subsides need to be provided in oder to promote equitable access to utility services. Some utilitties have introduce life line tari ffs in which minimal levels of utility services are provided free or at a low cost. Essentially, the UNSGAB,2008 undeniably illustrate that 12% of sub-saharan africa national health budget is spend only in providing sanitation and related health services and 50% of the hospital beds are occupied for the same reason. However, experts predicts by 2015 2.1 billion people will still lack sanitation especially in sub-sahara africa untill 2076 (ENS,2008) news. In contrast, some sub saharan African leaders invest a lot of funds in the area of infrastructure and services in water and sanitation primarily into public sectors with other development partners even though these funds are decreasing for various reasons and the share commercial is financing is still very low. The Ghana water and Sewerage Coporation(GWSC), a public utility charged with the responsibility, among others, of achieving self financing status however due to lack of political will by the government over the years to institute adequate tariffs devastated the finances of the GWSC(George Akosa,1995).This situation ,coupled with the general declined of Ghana economy,resulted in most of the operational water supply projects being in a poor state of repair of lacking the installed capacity to provide adequate service.We will probably say the government does invest is only the population in Africa growing leading the people in an extreme poverty from 44.6% to 46.4% as shown in ap pendix 4,10. Furthermore, Ghana is reported to be on track to meet the target of halving poverty by 2015(UNESC,2008) it is yet uncertain if sanitation will be met. There is an improvement in the HIV but the deadlock is still unmet in basic sanitation.USAID argued that should the current progress continue as it is now only water and sanitation in all countries will be met by 2015 whiles (UN News Center,2008)secretary general Ban Ki Mo affirm lack of political will will be the biggest obtacle to imrpoving sanitation on world water day. (vandemoortele,2002) ,considering the perceptions incurr by similar reports and journals that government investment is far less.(Ekow.E,2008)demonstrated that special issue of energy policy on energy in Africa with case studies on Zambia, etc explained at least the political will of many governments to improve the quality and quantity of energy services as a prerequisite for the achievement of the Millennium Development Goals. More significantly, unwill giness of government or political interest in sanitation per say,J.Edgardo campos and sanjay pradhan(2007) found that tackling corruption in the water and sanitation sector in some part of Africa was the primary reason for the MDGs not been on target as stipulated. Osumanu Issaka Kanton in Ghana mentioned African governments, like most countries in the developing world, face daunting tasks in their attempts to provide effective and equitable water and sanitation services for their ever increasing urban population,the paper however, contrasted that since the early 1990s the government of Ghana and many local authorities have entered into various public-private partnerships in urban water and sanitation using Tamale as a case studies where private has done nothing invigorated public sector not have achieved and therefore concluded that there can be no sustainable improvement in water and sanitation provision without political commitment, stakeholder ownership and strong support for co mmunity driven initiatives(2008) 4.Over population Poulation change seen as the major propeling factor for the MDGs in developing country with regards to water and sanitation(UNWPP,2005), (ENS,2008). fig 8 shows summary in the graph. The data from these graph was available from mainly from the estimates an medium variant. USAID monitoring report for 2006 MDGs, for instance, found that family planning practice will enhance the unmet MDGs to achieve the Goals by reducing the size of the targetted population groups which will then lowering the costs of meeting the MDGs in Sub-saharan Africa. Fig 9 table I.1 illustrates the report survey.Untill recently, (Esmarie Swanepoel,2008) publised article detailing africa falling behind on millennium development goals-UN as the proportion of people in sub saharan africa living below poverty decreased from 55.7% in 1990, to 50.3% in 2005. However, because of the population growth, the number of people in the region living in extreme poverty, grew by 100 million over the period. Using the below proj ections, the author (Dr.Jean –C. 2006 ) and others have reported distinct effect population growth has on Sub-sahara in terms of unsafe drinking water and sanitation in meeting the MDGs by the anticipated or stipulated year. Factually, the world health organisation (WHO,2004) annual assessment report substaintiate by saying that the world is on track to meet the drinking water target, but sub-sahara africa lags behind and conflict and political instability is a contributory factor with high rate of population growth and low priority given to water and sanitation will be a mirage. The paper concluded that whats more is the reason been the breakdown of water supply systems in rural africa is of high rates. One of the effective approaches shown to be accetable and helping the progress process drawn by the paper was decentralising responsibility and ownership and providing a choice of service level to communties based on their willingness and ability to pay.Urban population growt h was estimated to increased in growth in developing countries from 1.9 billion to 3.9 billion 2030, averaging 3.2% per year which is a major challenge for achieving MDG sanitation(UNESCO IHE,2007). The diagramme in fig 8 and fig9 indicates the percentage of the population living in major cities. The arguement goes to intensify the fact that water supply and sanitation will be an acute shorter for a decades to come. Source :UNICEF(data online) 5. Conclusion In short this paper looks at the slow progress of Millennium Development Goals with focus in developing countries especially sub saharan africa with respect to water and sanitation and various factors affecting the progress.The article then went further in reviewing various studies and literature presented by authors , analysing other views in the subject area and detailing sanitation situation in the case of Ghana. It was found that the systems of infrastructure has made it difficult for the MDGs team to montior effectively the progress and concrete availability of data was inevitable for correlation in knowing the exact people in sub saharan africa that are not covered as far as water and sanitation is concern. Governments interest in investing much funds in sanitary projects was seen lagging other projects in Africa even like health sectors was seen stampeding such as water sector was progressing steadily as compared to specifically sanitation due to high poverty in some countries and HIV/AIDS among others demanding. Therefore,the was the need for donor organisations to increase aid for the developing world. High population growth and inapproperiate use of low technologies were another contributory constraints in achieving the MDG since the number of populates in african countries was increased drastically by a substantial amount with diseases and malnutrion been high among children 0-5 years of age and rising in birth was due to either unexpected pregnancy or unaware or misapplication of farmily planning medicine at their possession. Skilled labour constraints therefore was one of the impediments that contributed tremendously bad towards the goals of the MDG in wardly due to the fact that skilled migrates leave the developing countries not only for better salaries and rumerations but virtue of better health care systems in developed world. In some cases institutional capacity building was seen as vital challenge for the MDGs in africa which some where in Asia for example Nepal it was much the same similarity. However, despite various studies been carried out by viable institutions and authors with different methods of approaches in addressing the Millennium Development Goals in water and sanitation, the plans has little consistency between different countries , thus making it difficult for policy makers to measure and track progress and so therefore Septentie appraisal of attitudes of stakeholders to the factors limiting progress to MDG.

Poor families have worse health conditions than those with higher incomes. Health is paramount for poor people and in most instances, their very environment is a threat to them. Improving environmental conditions including providing water, sanitation and solid waste management services is basic to the creation of sustainable livelihoods and the elimination of poverty. Water related diseases like guinea worm and trachoma still plague portions of West Africa. A person suffering from guinea worm looses a lot of productive farm time which reduces their income. Ghana is currently one of the leading guinea worm endemic countries in the world. Lack of political will biggest obstacle to improving sanitation – Secretary-General 22 March 2008 – A lack of political will remains the greatest obstacle to efforts to drastically reduce the number of people without access to basic sanitation and clean, running water, Secretary-General Ban Ki-moon said today, calling on the international community to take firmer and faster steps to tackle the problem. If we take up the challenge, the positive impact will reverberate far beyond better access to clean water, Mr. Ban said in a message to mark World Water Day, which is celebrated today. This years Day also coincides with the International Year of Sanitation. Every dollar invested in water and sanitation yields an estimate seven dollars worth of productive activity. And that comes on top of the immeasurable gains in cutting poverty, improving health and raising living standards. The Secretary-General described it as unconscionable that a child dies on average every 20 seconds because of sub-standard sanitation conditions – a situation endured by an estimated 2.6 billion people worldwide, or more than a third of the global population – that are preventable. Poor sanitation combines with a lack of safe drinking water and inadequate hygiene to contribute to the terrible global death toll. Those who survive face diminished chances of living a healthy and productive existence. Children, especially girls, are forced to stay out of school, while hygiene-related diseases keep adults from engaging in productive work. Halving the proportion of people without access to basic sanitation is one of the eight Millennium Development Goals (MDGs) devised at a global leaders summit in 2000, but the world is far behind the pace to achieve that by the target date of 2015, Mr. Ban said. Experts predict that by 2015, 2.1 billion people will still lack basic sanitation. At the present rate, sub-Saharan Africa will not reach the target until 2076. This years World Water Day also coincides with the International Year of Sanitation. Population growth, widespread poverty and insufficient investment are among the key obstacles, but the Secretary-General noted that the biggest culprit is the lack of political will. Events are being held around the world this weekend to highlight World Water Day, including the staging of a public toilet queue demonstration to raise awareness about the sanitation crisis around the globe. A similar event was held in New Yorks Central Park on Thursday. Wold bank graphic showing the failure of Africa to meet the MDGs.

Apollo 13 Essay -- Apollo 13 Essays

Apollo 13 Questions 1.I’d first have to say that the head of mission control on the ground was definitely important in the salvaging of Apollo 13. He was faced with problem after problem yet he kept a somewhat level head through all of it and managed the engineers and other people involved back at Houston very well. Jim Lovell’s piloting skills played a rold in the crew’s survival as well. When he had to set the ship’s course for Earth manually it took a great deal of skill and patience and he deserves credit for that. Ken Mattingly might not have made it to space, but his extensive knowledge of the ins and outs of the spacecraft saved the lives of his friends when they had a power crisis. 2. One particular problem during the Apollo 13 mission was a build up of carbon dioxide in the spacecraft. The CO2 scrubbers designed to filter out the gas weren’t working properly and as time progressed and the astronauts breathed more the situation worsened. To solve this problem NASA pooled together some engineers to come up with a design for a makeshift filter using common items onboard the space craft and an existing filter from another section of the spacecraft. 3. The general public and the press seemed disinterested with the Apollo 13 mission. Since we’d already beaten the Russians to the moon, no one in the general public put much interest into NASA anymore. The space race was decided and the public lost interest in NASA With no audience for the story, the...

Oedipus the King Essay

Man is the marionette in the hands of destiny. It is the circumstances and fate which bring tragic incidents in his life. The Aristotelian tragedies are generally based on this attitude. According to Aristotle tragedy is the representation of action. Common meaning of tragedies is the poignant end of the play. Here we are going to discuss about the two different tragedies which took place in different era. The first tragedy is the tragedy of â€Å"King Oedipus† which happened approximately 2000 years before and the second tragedy is the tragedy which belongs to the modern era. It is Arthur Miller’s â€Å"Death of a Salesman. † They are different from each other but apart from a long gap of about 2000 years, but yet some resemblances are there in them. We are going to discuss on the resemblances and differentiations. Let us consider â€Å"King Oedipus† first According to the rule of Aristotelian plot â€Å"Oedipus the King† is divided into two different parts, one is simple plot and another is complex plot. In simple plot the changes in the fortune of King Oedipus take place without Peripety and discovery. It is a journey from ignorance to knowledge. He has to confront with the consequences of the miserable truth. At first he is not ready to accept the fact but at the end the circumstances compel him to accept the reality. The protagonist, along with the other characters, totally becomes helpless in the hands of destiny. He is a king but the qualities of normal human beings are present in him. The tragedy takes place because of the sin he has committed inadvertently. According to the opinion of Aristotelian tragedies the hero of the play is neither perfectly good nor entirely bad. Oedipus thus is the man of ordinary weaknesses. He has had all the eminence but here he has shown falling into ruin from this distinction and it is unfortunately not because of any deliberate sin but because of the error committed by him in his ignorance. Like the protagonist the other characters in this play are also good but not perfect. For example Laios, father of King Oedipus who is of course a good soul but still he commits a sin of attempting the murder of his son at the infant stage of his life because of the fear that his son would one day kill him. â€Å"Laios had the feet of this child bound and pinned. Someone tossed it in a mountain wilderness. So there. Apollo didn’t cause this boy to be his father’s killer. Laios didn’t bear the terror he feared from his son. That’s what the words of prophecy defined. † (Line 717, Scene 3, â€Å"Oedipus the King†) The theory of tragedy of Arthur Miller is based on the life of an ordinary man. Miller was rejected by many critics because his tragedy was not based upon the Aristotelian concept of tragedy where the tragic hero is always a king or a prince. On the contrary the hero is a common man and so according to the critics he is unable to arise the tragic sentiments. But it was the belief of Miller â€Å"that the common man is as apt a subject for tragedy in its highest sense as kings were. On the face of it this ought to be obvious in the light of modern psychiatry, which bases its analysis upon classific formulations, such as the Oedipus and Orestes complexes, for instance, which were enacted by royal beings, but which apply to everyone in similar emotional situations. † (an essay by Arthur Miller, â€Å"Tragedy and the Common Man†) With the same viewpoint Arthur Miller has depicted the tragic story of a very simple ordinary man, Willy. Willy is an ordinary person by occupation as well as by nature. Not only Willy but rests of the characters are the exact mirror image of the ordinary man in the modern society who is constantly pursuing the materialist happiness. According to Miller it is not only the kings that can be the tragic heroes but the common man can also play the role of a tragic hero. As far as the issue of morality is concerned both plays are somewhat similar and somewhat reverse to each other. Morality plays a very important role in both of this play but still it defers from one another. Many people believe that Oedipus is an immoral person but it is not a premeditated immorality. Oedipus’ tragic fall, which later leads to tragedy was absolutely not his sin. He slays his biological father and marries to his biological mother. It is actually the height of immorality but at the time of committing this sin Oedipus was totally unaware about the reality. In short he is the immoral man by his predestined actions. The concept of morality is deliberate in Miller’s â€Å"Death of Salesman. † Here the hero of this play Willy Loman flouts all the rules of morality. He is charlatan, flirt and a liar. The lack of morality finds there in the Loman’s family itself. He goes on deceiving his wife by keeping illicit relationship with another woman. He goes on deceiving his son and wife by making his false image and by pretending to be an important person. â€Å"They don’t need me in New York. I’m the New England man. I’m vital in New England. † (Act 1, Part 1, pg. 4, Death of Salesman) But it is an illusion. Pride is there in both Oedipus and Willy but pride of Oedipus is at least genuine unlike to that of Willy which is just a fake. The heroes of both of the plays have to pay a lot and both of them have suffered a lot due to the mistakes they have done either ignorantly or deliberately. Both Oedipus and Willy in the end succeed in getting the sympathy of the audience. â€Å"I don’t say he’s a great man. Willy Loman never made a lot of money. His name was never in the paper. He’s not the finest character that ever lived. But he’s a human being, and a terrible thing is happening to him. So attention must be paid. He’s not to be allowed to fall into his grave like an old dog. Attention, attention must be finally paid to such a person. † (Act 1, Part 8, pg. 40) Apart from being an ordinary man Willy like Oedipus deserves the sympathy of the audience.

Sarcoidosis

Sarcoidosis is a multi-system disorder that is caused by inflammation of body tissues. It particularly affects the lungs and lymph nodes but it can affect any other body parts. The cause of this disorder is yet to be established and its cure has also not yet known. Its symptoms in most cases come gradually but might after some time appear abruptly. This paper is going to have an in-depth analysis of what perhaps leads to this disorder, give some of the symptoms that are characteristic of this disease, its possible treatment and the group that is most affected by it. The disease was identified for the first time over a century ago in England by a doctor known as Hutchinson and another doctor from Norway called Caesar Boeck and that was why the disease originally came to be referred to as Boeck’s or Hutchinson’s disease. Unfortunately, it is the young persons mostly those within the age bracket of 20 to 40 years and those that look strong and energetic that are affected (Baughman, 2006). Its appearance might at first appear to be mild but after sometime this may turn to be fatal. This disorder when this disorder is critically analyzed, it seems to vary across gender as it is women who are more affected than men and this is a claim that is supported by a survey that was conducted by the American Lung Association that revealed that black females are affected almost twice as much as black males are affected. According to the same report, it is also dependant on racial background as in most cases it is the blacks, Danes and Swedes that are affected most. Reports available show that blacks are affected more than whites in fact, the mortality rate of the former is sixteen times than the number of the whites that are affected (Stein, 1998). The disease effects can start affecting any organ and then spread to other organs. â€Å"Sarcoidosis†¦ can appear in almost any organ in the body, although the inflammation of the body’s tissues can begin in any organ and usually affects more than one organ† (Ebony, 106). The affected organs develop microscopic lumps which are known as granulomas that may last for some time and then disappear even without any medical intervention is done but in cases where they do not disappear, the skin may become scarred and inflamed. The affected persons may start complaining of fatigue but because they look young and energetic, doctors might fail to diagnose them for this disorder until it is later clearly suspected to be the one and an X-ray is conducted or a routine physical examination of the chest is conducted. This is what happened to one former marathon runner who says that she started complaining of fatigue long before but her doctor would dismiss her claims as unrelated and would attribute them to her stressful workload. According to her, she may have developed the disorder within a period ranging from one to sixteen years as it is only in 2001 she was diagnosed of the same (Ebony. 2005). People affected by this disorder say it is hard to describe how they feel when sick as one never gets refreshed even after resting. Generally, the common symptoms that are reported are that the victims generally become fatigued, lose weight, have blurred vision, sometimes gasp for breath, and have dry eyes and report of dry cough. It may also occur abruptly where rashes may appear on the skin and some bumps appear on the forehead, face and eyes inflammation (Swierzewski, 2000) Most of those affected by sarcoidosis about (60-80) % heal particularly after 2-3 years without having any medical attention. In most cases, those affected by this disorder do not know that they affected and end up having damaged lungs. If this disorder does not disappear immediately, it remains on a low level but might with time progress on. About 10 to 20 percent of cases of sarcoidosis are a bit serious and can lead to permanent debilitation while it is about only about 10 percent of sarcoidosis cases can be fatal (Schiff et al, 2006). There tends to be some relationship between how serious the disease begins and how it progresses and ends. In most cases, if nodosum appears suddenly there is a high possibility that the pains will be short-lived and ends without being treated According to statistics, thirty to seventy percent of the victims do not have any serious health complications that might require medical attention but sometimes these patients are given some therapeutic treatment like corticosteroids although it is not very clear whether the disease is reversed or not. There have also been cases where steroids such as methotrexate and azathioprine have been used in treating the disease (Baughman, 2006). As this study has established, sarcoidosis is a disorder that affects virtually all body organs but the most affected are the lungs. It leads to the development of some microscopic lumps that with time causes skin rashes. According to studies that have been done, the disease mostly affects people of African American decent, the Swedes and the Danes more than it affects the whites and to make the matter worse, those in the age bracket of 20 to 40 years. The cause of the disease and cure has not yet been established although some therapeutic medical interventions are given.

To What Extent Does Britains Welfare System Provide for the Needs of Its People Essays

To What Extent Does Britains Welfare System Provide for the Needs of Its People Essays To What Extent Does Britains Welfare System Provide for the Needs of Its People Essay To What Extent Does Britains Welfare System Provide for the Needs of Its People Essay A welfare state is a concept of government where the state plays the primary role in the protection and promotion of the economic and social well-being of its citizens. It is based on the principles of equality of opportunity, equitable distribution of wealth, and public responsibility for those unable to avail themselves of the minimal provisions for a good life. The general term may cover a variety of forms of economic and social organization. 1] There are two main interpretations of the idea of a welfare state: ? A model in which the state assumes primary responsibility for the welfare of its citizens. This responsibility in theory ought to be comprehensive, because all aspects of welfare are considered and universally applied to citizens as a right. ?Welfare state can also mean the creation of a social safety net of minimum standards of varying forms of welfare. ?Explanatory Notes? ^ [1] Encyclop? dia Britannica A Brief History of the British Welfare State The primary idea underlying the platform of the British Labour Party was the rather obvious idea that it was part of the governments responsibility to help find solutions to the major social problems facing its citizens. The questions surrounding the possibility of successful Implementation of these solutions at been at the core of the the contention that existed between the opposing political ideologies. The onslaught of German aggression in World War II forced Britain into a situation where it no longer had any choice but to give in to ideological pressures and put them into practice. By the conclusion of the war pretty much all doubt had evaporated in the clouds of bombs as to whether a welfare state policy was practical. Upon the somewhat surprising sweep by the Labour Party into the halls of power in 1945, the United Kingdom underwent a wholesale change in ideology. The Labour Party wasted precious little time in mandating a series of programs aimed directly at revolutionizing every aspect of British society. It initially accomplished through an aggressive agenda involving the nationalization of various systems such as power industries and the the health care and insurance systems, among others. The aim of these moves by the Labour Party was nothing less than full employment throughout the country with the most basic needs to be provided by the government. The intention was certainly good, but the economics failed to take into account the changing nature of the world. England was able to burst out of the post-war gate quicker than many others, especially the losing side, but eventually had to face its own lack of resources, which required borrowing money that was to be paid as the post-war boom continued. That boom, in fact, did not continue and rather than quick repayments, the country fell deeper into debt. Meanwhile the costs of running government programs continued to rise far beyond the capacity to maintain them. Psychologically, the welfare state contributed to the rise of a certain type who expected to be taken care of without contributing. This type is often overdrawn by those opposed to socialist programs, but it nonetheless carries a poisonous strain that must be dealt with. With the rising debt and the subsequent unemployment, however, England failed miserably at dealing with this element. As a result, the Conservative party seized the concept of a nation that succeeded only in producing lazy citizens who expected the government to take care of all their needs. As the economics of the world changed, the architects of the welfare state failed to make adjustments, setting the stage for the deep divide and miserable governance of the 1970s. The Conservative leaders capitalized on the deepest fears about socialism and as a result the Thatcher era was ushered in with a mandate to take any steps necessary to fix the problems. Although deemed a socialist policy of governance, the failings of the British welfare state may rest in that it wasnt socialist enough. Rather than fully commit to a true socialist state, the Labour Party attempt to create a hybrid of socialism and capitalism and as a result the worst aspects of each economic theory served to undo the better aspects. Britains welfare system now needs urgent reform Britains welfare system now needs urgent reform The National Health Service is considered to be one of the best healthcare systems in the world by the World Health Organization. But in recent years, administrative difficulty has become a big problem for fulfilling the need of the British people. Britains benefits bonanza has been laid bare as it emerged 100,000 households rake in more than the average wage in welfare every year. They collect ? 30,899 (Dh182,304) before tax, while many workers an only aspire to an average wage of ? 23,422. Meanwhile 50,000 of those households are entitled to more than ? 500 a week - which adds up to more than ? 26,000 a year. Officials at the Department for Work and Pensions highlighted the figures after the coalition pledged an overhaul of the welfare system to make work pay. Employment Minister Chris Grayling said: Yet again we see more evidence for why reform is so desperately needed. The current wel fare system is not fit for purpose. After a decade of economic boom there are 2. 5 million people on incapacity benefit. It is the whole society’s job to face up to this challenge and take on those who say recession is a convenient excuse to do nothing. We cannot afford to do nothing. We need a robust welfare system able to withstand every twist and turn of the economic cycle. A strong welfare state will help everyone, be flexible enough to adapt to changing circumstances and offer real financial incentives to get people into sustainable work. Bescides this,the British prime minister David Cameron stressed his commitment to cutting the country’s deficit and said an overhaul of the welfare system would soon begin.

Attendance System Using Fingerprint

Attendance System Using Fingerprint The project entitled â€Å"ATTENDANCE SYSTEM USING FINGERPRINT† is to provide an authentified attendance system for Roots Industries Limited. This software provides various information, which is useful for user as well as administrator. This software can be used as a whole in organization, or can partly used as separate modules, whenever needed. The project deals with capturing the thumb impression of the employee through the thumb scanner and authenticates with the already registered impression. Attendance will be marked for the matched employee. With the in-time and out-time, the total hours worked by the employee in a day and days worked for the month is calculated. The salary is calculated from loss of pay, basic pay, allowances, and deductions. One of the main advantages of this software is its user friendliness and validation can be done for each and every employee entered. New entries can be registered very easily and if not needed then it can be deleted from the softw are. The environments being used are VB.NET as front end and SQL Server as back end. This project is developed in the Operating System, Microsoft Windows XP. CHAPTER I INTRODUCTION This chapter contains the problem definition, about the system environment and the organization profile which gives details about the company. PROBLEM DEFINITION OBJECTIVE AND SCOPE The main objective of this project is to do the following operations Thumb impression Comparisons Attendance Calculation Payroll Calculation The scope of the project is to capture and verify the thumb impression of the employee. And also provide effective means to calculate attendance and payroll for the employee by using thumb impression. This project would greatly help in simplifying the manual attendance calculation and payroll calculation. PROBLEM DESCRIPTION This project makes use of fingerprint to authenticate the employee. This project makes use of the physical hardware device, the thumb scanner to capture the t humb impression of the employee. The Administrator registers the details of new workers. He also registers the unique thumb code of the employee generated by the Thumb scanner. This thumb code is generally an alphanumeric code and it is stored in the database. The employee uses the thumb scanner when he enters and leaves the work place for attendance marking. The generated code is matched with the stored thumb code in the database. The attendance is marked for the corresponding employee where thumb code matches with the generated ones. If there is no match with the thumb code then the administrator will take in charge to check whether the person is a new employee or not. The time duration between intime and outtime is calculated and it is stored as hours worked by the employee. Each time when the outtime is marked the duration is calculated and hours worked (field) is updated. The employee may take leave. The leave taken by the employee is calculated as loss of pay for him. It will be used to calculate net pay for the employee in the payroll calculation. During salary calculation the monthly attendance of the employee, loss of pay, the allowance such as HRA, DA and deductions such as PF, LIC are considered.

Mitochondrial DNA (mtDNA) characteristics and uses Assignment

Mitochondrial DNA (mtDNA) characteristics and uses - Assignment Example DNA sequence determination of the mDNA has been from many organisms including the extinct ones, and the comparison of the sequences outlines the mainstay of phylogenetics. The researchers have therefore been able to elucidate various evolutionary relationships within species. Additionally, the analysis of the relatedness of the populations among organisms has been ascertained and has become vital in the field of anthropology. The human mitochondrion DNA as an example, is commonly present per every cell except in sex cells as elucidated by Brown, George & Wilson, 1979, and is closely related to that of metazoans. The circular double-strand molecule of mDNA has about 15000 to 17000 base pairs and the nucleotide content differentiates the two strands. In animals, the transcribed strand produces molecules of polycistronic RNA. In replication process, the mDNA is replicated by the gamma complex of the enzyme DNA polymerase that is composed of 140 kDa of the catalytic section of the enzyme encoded by the gene POLG and two accessory subunits of 55 kDa encoded by POLG2 gene. During the process of embryogenesis, the mDNA replication is down because it is regulated from the oocyte that is fertilized through the embryo that is pre-implanted. At the stage of blastocyst, Anderson et al, 1981, further exemplifies that onset of the replication of the mDNA is specific to the trophectoderm cells. In contrast, the replication of mDNA is restricted by the inner cell mass cell until they receive signals making them differentiate to specific cell types. In the susceptibility concept, the mDNA does not necessarily accumulate many oxidative base damages than the nuclear DNA. As a result, some other types of the oxidative DNA damage are more efficiently repaired in the mitochondria than in the nucleus. The presence of proteins in the organelle further offers protection just as in the nuclear chromatin. The integrity of

Should the DREAM Actor legislation like itbe passed Essay

Should the DREAM Actor legislation like itbe passed - Essay Example Every day, immigrants in the United States feel alienated from the society. It may start at an early age or during the teenage year after enrollment to advanced educational institutions. This prevents them from taking part in activities that benefit the society. Immigrants are also denied opportunities which may help build them morally and psychologically. In most cases, immigrants are the best performers in educational institutions. However, they have to go through many hardships so as to afford to pay for their education and also to secure a job in the job market. In turn, this denies them the chances to benefit the society economically. For undocumented children, securing a place in schools and other educational institutions is hard enough. If the manage to enroll to a school, another problem arises in paying their school fees. Sometimes, they may even have to take breaks so as to work. In the worst case scenarios, they even end up dropping out of school completely. However, this is not even half the challenges that they have to go through in their day-to-day lives. For a child to develop psychologically, he/she needs to have a sense of belonging either to a community, a state or a certain social group. Undocumented children are denied this opportunity by being denied certain privileges such as social security numbers and ID cards. This prevents them from taking part in social activities and having fun like other documented teenagers. One of the reasons and explanations, as to why I think the dream act should be passed is because it recognizes undocumented children. The Dream Act gives undocumented children the chance to participate in economic activities and also further their education. As stated previously, many undocumented children are good performers in their studies. However, they end up dropping out of school due to lack of school fees. For example, â€Å"The ‘Invisibles’†, an article written by Doulas McGray, states â€Å"In 2004,

Whether the prisoner can be tortured to obtain the information needed Essay

Whether the prisoner can be tortured to obtain the information needed - Essay Example Terrorists are a group of people dedicated to a cause who perform an unconventional act of violence against civilians for political gain. While Prisoners of War can be held without answering any questions except for name, rank and serial number, terrorists are criminals. Terrorists need to be captured and brought to trial. If American troops capture the terrorist, they need to be sent back to American to be tried. If a foreign government or army captures a terrorist, the American government should follow the extradition laws of the foreign government. In the case of the captured number two Al Qaeda terrorist, he should be questioned. If he refuses to talk, this terrorist must be sent to a federal prison to await trial. He should not be tortured, but the terrorist does not necessarily have the rights of an American citizen. That means they can be held in the comfort of a federal prison for an undetermined length of time, until a trial can be arranged. That is not torture. Torture is defined as anything that causes pain to punish or coerce. It would be unethical to withhold medical attention from a terrorist. The use of beating, punching or any other physical means of torture would also be wrong. It is also wrong to withhold food and water from a prisoner. Now psychological torture is different. Loud noises, bright lights, isolating a prisoner or even having the prisoner remain nude is humane. Americans employ these methods against unruly prisoners in America. These psychological methods will not permanently harm a terrorist. So they could be used against the number two Al Qaeda man to find out information. Victims and the victim’s families of 9/11 might disagree with giving a terrorist any rights. If the 9/11 tragedy could have been prevented by torture, some would argue that the means would justify the end. In a perfect world this argument would be true. If American Intelligent was a perfected science, where the military would know

According to Williamson and Lindert (1980), the movements of the skilled and unskilled pay ratios clearly reflect the unequal distribution of wealth particularly between men and women. (Williamson and Lindert, 1980) Industrialization resulted to a lesser demand for human resources. This causes the increase in competition among the workers. The unequal resources such as the access to education between the rich and the less fortunate people resulted to a wider gap on the distribution of wealth between the two sectors of the society. This paper will discuss in details the effects of the inequality in the distribution of earnings, income, and wealth among men and women as a family in comparison to the case of single mothers as well as other factors such as the economic performance of the country and the UK tax reform. These factors could greatly affect the income-leisure time of women. On the other hand, the use of ‘Income-Leisure Choice Theory model’ could give us a better outlook on how working women or single mothers often end up working for longer hours The constantly changing working environment has resulted in the changes of employment patterns among men and women over the past decades. According to OEDC – Employment Outlook, the number of women participation in the corporate world has constantly increasing; while the men continuously declining. Specifically, the gender wage gaps between men and women in terms of their median earnings are wide. (See Table I – Gender Gap in Median Earnings of Full-time Employees in 2004 below and Graph I – Gender Wage Gaps on page 5) Since the earning gaps between men and women are quite big, women especially those who are single

Should the DREAM Actor legislation like itbe passed Essay

Should the DREAM Actor legislation like itbe passed - Essay Example Every day, immigrants in the United States feel alienated from the society. It may start at an early age or during the teenage year after enrollment to advanced educational institutions. This prevents them from taking part in activities that benefit the society. Immigrants are also denied opportunities which may help build them morally and psychologically. In most cases, immigrants are the best performers in educational institutions. However, they have to go through many hardships so as to afford to pay for their education and also to secure a job in the job market. In turn, this denies them the chances to benefit the society economically. For undocumented children, securing a place in schools and other educational institutions is hard enough. If the manage to enroll to a school, another problem arises in paying their school fees. Sometimes, they may even have to take breaks so as to work. In the worst case scenarios, they even end up dropping out of school completely. However, this is not even half the challenges that they have to go through in their day-to-day lives. For a child to develop psychologically, he/she needs to have a sense of belonging either to a community, a state or a certain social group. Undocumented children are denied this opportunity by being denied certain privileges such as social security numbers and ID cards. This prevents them from taking part in social activities and having fun like other documented teenagers. One of the reasons and explanations, as to why I think the dream act should be passed is because it recognizes undocumented children. The Dream Act gives undocumented children the chance to participate in economic activities and also further their education. As stated previously, many undocumented children are good performers in their studies. However, they end up dropping out of school due to lack of school fees. For example, â€Å"The ‘Invisibles’†, an article written by Doulas McGray, states â€Å"In 2004,

Gender Ideologies in Local Context Essay Example for Free

Gender Ideologies in Local Context Essay Present essay deals with analysis of gender ideologies’ functioning in certain local contexts. The latter is discussed through the prism of interactionist approach, which seems to be the most effective in terms of describing micro-level at which gender ideologies function. It provides with possibilities for studying how performative, discourse and social strategies of actors realized in local contexts are embedded in general gender ideology framework. For the present analysis a bar was chosen as the local context, where field study was conducted and gender ideologies’ reflection in interactions between men and women were analyzed. The central research question of this paper, hence, may be formulated as follows: how do gender ideologies shape interactions between men and women in bar or night club? Gender ideologies in local contexts: interactionist approach. Gender ideologies represent certain social and cultural constructs, which structure the perception of female and masculine identities, societal roles, family status and production relations etc (Philips, 2). Gender ideologies should be understood as a product of social structure, which fosters different roles of men and women in society. For instance, it may be said that currently dominant perception of women in society was formed within predominantly patriarchal discourse. Paradoxically, patriarchal perception of women affects their own gender ideology and identity, which often corresponds with socially constructed identity. Hence, women’s interactions with men are affected by the absence of their organic self-identity – they are forced to interact within the discourse created by men. However, the latter is realized through women’s own discursive system, which may be described as the micro-level of gender ideology. As Lakoff suggests, women and men learn their distinct languages from the childhood, which being the part of universal language, in fact reflect different identities in gender interactions (Lakoff, 222). Interactions, according to interactionist approach are based on endowing of certain subjective actions of the Other with meaning and symbols (Blumer, 45). In gender interactions, such meaning is ascribed to actions, based on gender ideologies. For instance, as Lakoff suggests of women’s discourse, ‘If she refuses to talk like a lady, she is ridiculed and subjected to criticism as unfeminine’ (Lakoff, 222). The latter example shows that gender ideologies are genuinely embedded in gender interactions, because they form the frame of understanding, actions’ meaning and behavior. Moreover, as Lakoff suggests, there exist considerable differences between women’s and men’s use of vocabulary, especially as far as the use of strong words, adjectives and particles are concerned (Lakoff, 223-224). The latter may be evident in any local context, including gender interactions in bar or nightclub, as it would be shown. Any local context activates specific aspects of gender ideology. According to Philips, notwithstanding culture, ‘There are at least four aspects of human experience that regularly enter into gender ideologies. These include work, appearance, sexuality and reproduction’ (Philips, 8). There is no denying the importance of the fact, that in the interactionist context, analyzed in this paper, such aspects as sexuality and appearance come into play in the first place. Based on these general theoretic considerations concerning gender ideologies let us analyze their reflection in concrete location’s context of bar, based on the empirical data collected in the field study. Gender Ideologies in gender interactions in bar Field research for this study was conducted in Dirtbags Bar and Grille in Tucson, AZ on June 1, 2009 during 10:30-Midnight. The data collection orientation focused on observing how gender ideologies affect gender interactions in this situational context. The first observation includes objective behavioral patterns of men and women during their visit to bar. It was established as a fact, that men may arrive to bar both in 3-4 individuals groups and alone. Women, as the field study found never arrive alone, but only with their boyfriend of female friend. The latter situation may be interpreted through the prism of Butler’s approach to gender identity construction. According to Buttler, identity is constructed based on repetition of certain behavioral patterns, gestures, discourses etc (Butler, 519). The latter implies that social structures, existing in society already provide women with stable behavioral orientations, taught to them by their families, older friends. One of such behavioral codes, which are immediately linked to gender ideology may be described as the cultural taboo for visiting entertainment public places alone. Such taboo is connected first of all with institutionalized male perception of women, being alone in the bar or night club, as the invitation for sexual relations. Based on this perception, visiting bar alone for women automatically means moral fault, since she is immediately associated with prostitute etc. Unlike women’s case, in men’s gender ideology the problem of man’s visiting bar alone does not exist, since it is not problematized as gender issue at all. Therefore, it is evident that men have more behavioral options and may choose between them to one’s own like. Buttler suggests that gender identities and ideologies are constructed through theatrical and performative interactions (Buttler, 520). The latter is particular evident in women’s focus on their dress, while visiting the bar. Women are more prone to put the emphasis on their own clothes and comment on the apparels of their female friends. They often made complements concerning good dress of each other. As the same time, men regularly have no tendency to comment on the clothes of their male friends. Instead, they often make complements to women concerning their dress. The latter observations show that gender ideology functions through performative and theatrical behavior reflected in the culture of dressing. Men are relatively indifferent to what their friends wear, however, pay much attention to what women wear. The performative and theatrical role of gender ideologies is also evident in women and men behavior, when they enter the bar. Women express much more willingness to be noticed by public, including both men and women, as they immediately look for people they know. Unlike, women, men seem to be less tied by any social obligations as they often go straight to the bar and order drinks and only after this greet people they know. Moreover, a bar serves for men a spot to sit down, while women prefer staying near the bar and being attentive to what is going on around them. Gender ideological conventions concerning sexuality are also evident in the types of drinks ordered by men and women. First of all, male gender ideology is obvious in the wide-spread practice of ordering drinks by men for women, especially as the part of acquaintance or showing sexual interest. Such behavior is often welcomed by women, who are embedded in gender ideologies of men, because women are prone to interpret such attention as the marker of sympathy and often use it in their own interest. As far as the type of beverages, drunk by men and women are concerned, men usually do not differentiate between different drinks, while women often order low calorie beverages such as ‘diet coke and Bacardi’ or sugar free redbull. The latter shows that the majority of women are embedded in the discourse relating to their appearance and sexuality, which is according to Philips is one of the central aspects of gender ideology (Philips, 9). Women, embedded in gender ideology, try to follow its main conventions in any local context, including bar. Gender interactions in bar are also characterized by both and men and women behavior directed at emphasizing correspondingly their femininity and masculinity. Men in the conversation with women always try to lower the pitch of their voices, while women often raise it. As Tannen suggests, such strategies are inherently gender, because they are affected by existing ideological representations of femininity and masculinity (Tannen, 169). In these ideological representations masculinity is characterized by the low pitch of voice, which is associated with men authority and women’s high pitch, associated with her secondary role in society. Gender socialization patterns in bar are also very informative, as far as the reflection of gender ideologies is concerned. Women feel more comfortable always being in company either of their female or male friends. In contrast, men may be either alone or in company without any differentiation. For women being in company guarantees the stability of her identity, because she may fully realize her performative and theatrical patterns of behavior. In contrast, being alone often causes negative gender connotations. Gender interactions in a bar are predominantly initiated by men, when a member of a male group offers a drink to a woman or a group of women. Often women refuse such invitations, however, in a majority of cases they agree even if they feel compelled and uncomfortable in communicating with the large group of men. A man being alone, however, is less prone to initiate conversations with women, than if he finds himself in company. There is no denying the importance of the fact, that the discussed pattern of gender interactions in bar reflects certain features of dominant gender ideologies. As Butler suggests, gender interactions are regulated by social sanctions and taboos (Butler, 520). One of such taboos may be formulated as follows: women are generally not eligible to initiate gender interactions with men; such priority solely belongs to the latter due to their primary role in gender relations. The realization of this taboo is particularly evident in bar context, where women generally behave in such a manner in order to stimulate men’s interest, however, their own interests is hidden from public. A woman may be interested in communicating with a given man, however, due to certain gender limitations she is more likely to refuse from her ambitions. Moreover, men usually feel uncomfortable when gender interactions are initiated by women, because it is usually mocked up in his male company. Hence, it may be postulated that taboos and limitations relating to gender interactions exist both in male and female gender ideologies. If a woman and a man know each other they usually greet by hugs, kisses and even if they are not engaged in romantic relations, they often show some kind of flirting. In personal interactions between men and women gender ideologies are also evident in men’s primary role in initiating tactile closeness with women, especially after alcohol drinks, including closeness, flirt, kisses, hugs, joking etc. Women, interested in such gender interactions, would not hesitate to communicate and flirt. However, a woman, who feels uncomfortable in this situation, according to the field study conducted, tries to use any possibility to escape from such kind of interactions. Gender ideologies are also embedded in the purpose of men and women’ visiting bars. Men usually visit bars to chase after women and find the object of their sexual desires etc. Women may also visit bars in this purpose, however, their clear intentions are not seen so obviously as that of men, hence, we may speak of dubious nature of their purpose. Such distribution of gender roles clearly resonates with dominant gender ideology, according to which men have the priority in initiating close gender relations. As far as dancing practices in bars are concerned, men are less prone to dance alone; however, women have no qualms about it. Men prefer dancing if they want to initiate interactions with women – in such a case they dance close to her. Apart from this, gender interactions in bar are often characterized by age limitations. Older women rarely visit such kind of places; however, older men may be seen there more frequently. Conclusion Gender ideologies represent language reflection of certain social and behavioral patterns of men and women and society. They usually refer to different social roles, types of discourse, sanctions and taboos and behavior of men and women. The analysis of gender ideologies in local context of bar showed that they are reflected in concrete interactions. Men and women usually act according to well-established gender conventions of behavior, which are reflected in initiating interactions, purpose of bar visit, behavior in groups, intersexual behavior etc. Women seem to be considerably affected by their representation in men gender ideologies, which means that they have no behavioral choices. In contrast, men’s behavior is characterized by the possibility of choice between a wide range of options. Men may be either alone or with friends, initiate gender interactions or not etc. Women have virtually no choices: they have refuse from initiating interactions, positively respond to any men’s attempt to initiate communication, always be in a company etc. Moreover, gender interactions in bar reflect crucial social perceptions of women sexuality and appearance, which are the first aspect of gender coming into play in bar context. Women put emphasis on their appearance and clothes and often try to present their identity in performative and theatrical way, which according to Buttler, immediately links such kind of behavior to gender strategies. In contrast men, pay less attention to such things and behave in a more casual and free way. Finally, men’s behavior in a bar is regulated by the lesser number of social sanctions and taboos.

Stratospheric Ozone Depletion Research

Stratospheric Ozone Depletion Research A) Effects of Ozone on the Lower Atmosphere The lower atmosphere (Troposphere) includes 75% by mass of the atmosphere (concentrated). Natural sources of Ozone in the troposphere includes lightning. Approximately 10% of all atmospheric ozone is present in the troposphere. If ozone levels reach 20ppm, they are very poisonous to humans, animals and plants. It oxidises organic tissue which disrupts the normal biochemical reactions in the body, irritates the eyes and causes breathing difficulties. It can be detrimental to plants and agriculture, as it oxidises much more readily then oxygen, killing/spoiling the agriculture and destroying it. Sources of ozone in the troposphere include diffusion from the stratosphere, internal combustion engines, petrochemical smog, naturally from lightning and photochemically when nitrogen dioxide in polluted air is decomposed by sunlight. NO2(g) NO(g) + O(g) O2(g) + O(g) O3(g) Positive effects of ozone include that it can kill bacteria and viruses in water and thus is useful in purifying water supplies. B) Effects of Ozone in the Stratosphere Contrastingly to ozone in the troposphere, Ozone in the stratosphere is essential to life on earth, as it absorbs ultraviolet (UV) radiation which can be harmful to living cells on earth as they can damage living tissues and cause skin cancers. Ozone in the stratosphere is commonly referenced to as â€Å"the ozone shield† as it protects living organisms on earth from UV rays. Ozone Reactions in the Stratosphere and their Beneficial Effects on Living Organisms Formation of Ozone in the Stratosphere O2(g) O(g) + O(g) O(g) + O2(g) → O3(g) Stratospheric oxygen absorbs UV light to form free oxygen radicals The oxygen radicals are highly reactive and combine with oxygen molecules to form an energized ozone molecule. Decomposition of Ozone in the Stratosphere O3(g) O2(g) + O(g) Due to the absorption of UV radiation, the Ozone layer acts as a radiation shield by absorbing medium and high energy UV rays. This protects living organisms as UV radiation can have very harmful effects on them including: Can cause sunburn on skin which can lead to skin cancer caused by a mutation in DNA Can form cataracts on eyes It can kill cells due to DNA readily reacting with UV rays It can impair photosynthesis in plants Many more†¦ Thus without the ozone shield in the stratosphere, life in the biosphere would be dramatically impaired and destroyed by harmful UV rays. A) Functional Groups and General Structure of Compounds Classified as CFC’s CFC’s – Chlorofluorocarbons are haloalkanes in which the hydrogen atoms have been replaced by fluorine or chlorine atoms. Haloalkanes are the products when alkanes react with halogens (members of group 7 of the periodic table). CFC’s generally contain â€Å"chloro† and â€Å"flouro† functional groups and no hydrogen atoms. The general structure of compounds classified as CFCs are haloalkanes whose hydrogens have been replaced by chlorine or fluorine atoms. E.g. B) Main Uses of CFC’s CFC’s were used as refrigerants and as propellants in aerosol spray cans. They have a variety of uses as demonstrated below. However due to the harmful effects of CFC to the environment and the ozone shield, CFCs are not used for these uses anymore. C) Reactions between CFC’s and Ozone that Result in the Destruction of Ozone in the Stratosphere. Effects of Small Concentrations of CFC’s that can Damage Large amounts of Ozone Reactions between CFCs and Ozone Synthetic CFCs are responsible for the destruction of the ozone shield, natural CFCs such as CH3Cl and HCl rarely reach the stratosphere as they readily oxidise in the troposphere. However, synthetic CFCs slowly diffuse from the troposphere into the stratosphere, where they undergo photodissociation (due to UV rays) to produce chlorine and bromine radicals that attack and destroy ozone molecules. e.g. CFC-11 Trichloroflouromethane (CFCl3) (Lifetime of 70 years) 1. In the stratosphere, the CFC comes into contact with short wavelength UV CFCl3(g) + UV → CFCl2 ·(g) + Cl ·(g) 2. The chlorine free radical then reacts with the ozone molecule Cl + O3 → ClO + O2 3. The ClO molecule reacts with free oxygen atoms which exist naturally from UV breakdown of O2 ClO + O → O2 + Cl This Cl Is then regenerated and able to attack more Ozone (Step 2) thus further demonstrating the harmful effects of even one CFC This reaction causes destruction of ozone in the stratosphere, due to the (previously used) synthetic CFCs for refrigeration, dry cleaning etc. Small Amounts of CFCs can still do harm: Evidence has shown that even small amounts of CFCs can damage large amounts of ozone. Firstly, CFCs generally have a long lifespan, ranging from approximately 57 (CFC-11) years to 333 years (CFC-12), and due to the fact that each Chlorine radical can be responsible for the breakdown of tens of thousands of ozone molecules, and due to their lifespan once released, even a small amount, will be around for many decades to come. In addition, most CFCs will almost definitely make their way up to the stratosphere as they cannot be destroyed at low altitudes as they are unreactive and they are insoluble in water and therefore cannot be washed out of the atmosphere by rain. Alternative Compounds for CFCs. A) Ozone Monitoring Instruments Ozone Concentrations in the Stratosphere Source: Earth System Research Laboratory, 2012, Viewed 07.06.14, http://www.esrl.noaa.gov/gmd/dv/spo_oz/spototal.html A) Analysis of Trends There are a variety of trends that can be interpreted from the above diagram. Based on the data above, before the 1980’s, the total ozone concentration was VERY high, at approximately 194 DU (Dobson Units), however there was a very rapid decrease in this concentration from 1980 – 1999, whereby in this 19 year period sees a 56% decrease in the amount of total ozone, a remarkably concerning figure. On a year round basis globally, total ozone concentration have caused a 3-8% decrease in the amount of ozone, this increased in the years between 1995-200, where there was a low of total ozone concentration. However, in more recent years, 2010 to 2014 there has been a general increase in total ozone concentration, which can be inferred from the replacement of CFCs finally starting to impact (slightly) on the total concentration of ozone, this increase based on the data is 31%. The general pattern is that the total column ozone decreases during spring time, it can be inferred that the overall concentration of ozone decreases during this time of the year. This is because in an Antarctic winter, there is no U.V light to convert the chlorine molecule Cl2 into a Cl radical, which then destroy ozone molecules, and thus the concentration of ozone is higher in winter. In spring, the U.V light converts the Cl2 into Cl which then destroys ozone in a chain reaction, thus decreasing the total ozone concentration There are various peaks in the graph, in the years of 1988, 2003, 2011 and 2013, which may be due to limitation so of the instruments used. B) Montreal Protocol Effectiveness The Montreal protocol occurred in 1987, which the main aim was to control the production of ozone depleting substances (CFCs) worldwide. A number of amendments have been adopted to further ride ozone depleting substances. The protocol is applied in 193 countries. The main aims of the original agreement is as follow: Halt the use of Halons by late 1994 By the early 21st century, phase out the use of HCFCs Stop manufacture of CFCs by 1996 Allow for leeway with less developed countries but still get them to rid the use of these substances The Montreal Protocol (and amendments) has been effective as by 2006, the consumption of ozone depleting substances has been reduced globally by 96%. However, due to the long lives of the previously used ozone depleting substances, the total concentration will take hundreds of years to be completely down. However, the total concentration in the troposphere has generally been declining since the mid-1990s.
