Pros and Cons of Us Healthcare System free essay sample

Canada spends far less of its GDP on health care (10. 4 percent, versus 16 percent in the U. S. ) yet performs better than the U. S. on two commonly cited health outcome measures, the infant mortality rate and life expectancy. But what constitutes high quality health care? The U. S. Institute of Medicine’s definition, which has grounded expert work in the United States and elsewhere, describes quality as â€Å"the degree to which health services for individuals and populations increase the likelihood of desired health outcomes and are consistent with current professional knowledge. A healthcare system can be reviewed by many standards. It can be reviewed by its effectiveness and efficiency, its fairness and receptiveness to the expectations of its population. It can be reviewed through its non-discriminatory economic contributions and suitability and lastly, it can be reviewed through its population’s overall health. Both the Unites States and Canada have Medicare prog rams that are publicly funded.

These programs for example include the States Childs Health Insurance Program (SCHIP) for children of low income families and the Veterans Hospital Administration Program (VA) which supplies military veterans’ with health benefits via a network of government hospitals. Canada’s government in contrast to the U. S. offers a single payer system for health care to its citizens where fundamental services are supplied by private physicians (socialized medicine). Physician care in the U. S. is typically provided by a physician in private practice but can come from the government as well. A good number of U. S. and Canadian physicians also utilize a fee per visit rate. Roughly 2/3 of hospitals in the United States’ urban areas are non-profit hospitals unlike Canada. Numerous citizens in both countries encounter difficulties obtaining access to health care. Many U. S. citizens either have no health insurance because they are not able to afford it or it is inadequate, unlike Canada where all members of society are covered for health care. Both Canada and the U. S. have restricted programs that supply prescriptions to the underprivileged. A number of provinces in Canada still charge individuals and families premiums and in the U. S, states like Connecticut and Minnesota have moved toward Universal Health Care. For the most part both countries seem to hold equal acceptability and equal restrictions. Essentially, when comparing and contrasting the U. S. and Canada, the Canadian health care system has a smaller number of physicians as oppose to the United States but there is more government involvement in the Canadian health care system than in the United States We will explore the positives and negatives of the U. S. and Canadian healthcare system. Given the presence of social insurance programs in the United States, this paper will evaluate the role of managed care approaches in meeting the cost-containment, access, and quality objectives of the two Health Care Programs in the United States and Canada. We will attempt to compare and contrast the benefits and liabilities inherent in the two neighboring countries. We will also focus our study on problem analysis; try to offer solutions and recommendations; and justify why our recommended solution and implementation will solve the identified problems. We will also determine which country’s approach is the most effective. Comparative Study of United States and Canadas Health Care System I. Problem/Issue Statement Medicare is facing a fiscal crisis that threatens its sustainability. The need for significant Medicare reform is increasingly urgent as 76 million baby boomers are expected to retire over the next two decade. According to the 201 Medicare Trustees Report, the Hospital Insurance trust fund will be depleted in 2024. This translates to $27 trillion in unfunded liabilities over the next 75 years. Current projections indicate that health care costs will increase by more that 70 percent over the next ten years and will continue thereafter to consume an increasingly greater portion of personal income. For Americans, health care coverage depends primarily on whether health insurance is provided by their employer or through two major public programs, Medicaid for the poor and Medicare for the elderly. For both public and private employees, health care benefits and cost vary tremendously. By making workers dependent upon their employer for health care, there is an extra burden on workers who are forced to change or lose their jobs in the U. S. Also, a growing number of people with a history of health problems, or with what insurance companies deem to be preexisting conditions, find themselves uninsurable. With rising health care costs, many employers in the private sector do not provide any health care benefits at all. Most employers, whether private or public, are attempting to shift the cost of health care programs onto workers. Medicare, for example, now covers only about 40% of the health care costs of the aged. II. Literature Review In 2009, Americans spent $7,960 per person on health care, while our neighbors in Canada spent $4,808. There are many possible explanations for why Americans pay so much more. It could be that we’re sicker. Or that we go to the doctor more frequently. But on close inspection, found that Americans don’t see the doctor more often or stay longer in the hospital than residents of other countries. Quite the opposite, we spend less time in the hospital and see the doctor less often than the Canadians. The United States spends more on health care than Canada without providing more services than Canada. Canada’s Health Care prices are set by the government. The creation of Medicare in Canada in 1966 rapidly led to government funding of much of the health system. The American government has also has become deeply involved in the delivery of health care, but has not created a system of universal government coverage. Comparing and Contrasting the U. S. Health Care System A healthcare system can be reviewed by many standards. It can be reviewed by its effectiveness and efficiency, its fairness and receptiveness to the expectations of its population. It can be reviewed through its non-discriminatory economic contributions and suitability and lastly, it can be reviewed through its population’s overall health. Roughly two-thirds of hospitals in the United States’ urban areas are non-profit hospitals unlike Canada. Numerous citizens in both countries encounter difficulties obtaining access to health care. Many U. S. itizens either have no health insurance because they are not able to afford it or it is inadequate, unlike Canada where all members of society are covered for health care. Both Canada and the U. S. have restricted programs that supply prescriptions to the underprivileged. A number of provinces in Canada still charge individuals and families premiums and in the U. S, states like Connecticut and Minnesota have moved toward Universal Health Care. For the most part both countries seem to hold equal acceptability and equal restrictions. Essentially, when comparing and contrasting the U.S. and Canada, the Canadian health care system has a smaller number of physicians as oppose to the United States but there is more government involvement in the Canadian health care system than in the United States (Holt , 2007, Para 7,8, and 9). Pros and cons in the U. S and Canadian Health care Systems As usual there are pros and cons to the Canadian health care system. For example a small number of well-revealed and somewhat erroneous cases show that has a con, Canada’s health care system is in great need of improved urgent care for its citizens requiring immediate treatment. Another con is that Canadians also pay higher taxes to pay for health care. Further examination reveals that as a con, the Canadian health care system does a very meager job at handling and controlling chronic disease. Furthermore, as a major con, the health care system’s wait time for elective care is way beyond the required time a citizen should have to wait for treatment and this includes appointments with family physicians, specialists and elected surgical procedures (Suphan 2009, para. 6). On the other hand, when viewing the pros of the system, all Canadians have insurance coverage for hospital and physician services. The citizens do not have co-pays or deductibles on basic health care services. In addition, the majority of Canadian provinces supply coverage for programs such as home health care, long-term care, pharmaceuticals and durable health care equipment, though these services do have minimal co-pays. The main pro that Canada’s health care system has are its costs. Canada pays out roughly 10% of its economic value on healthcare plus Canadians essentially receive more of the majority of services. Just as Canada has pros and cons to its health care system, likewise the United States’ health care system has pros and cons. One of the pros of the U. S. health care system is that its medical research systems are some of the best in the world. Institutions such as the Mayo Clinic, Cleveland Clinic and the medical school at Harvard possess some of the most world-renowned researchers in the world because of the advances they are making in medicine and also because of the current free-market system. Another pro to the United States’ health care system is that Americans’ who have enough money for it or those who possess jobs with great benefits have some of the best health insurance plans in the world. One more advantage of the present U. S. health care system is that taxpayers do not sustain the cost coupled with supplying health care insurance to all single people. Furthermore, the U. S. health care system as a major pro pays health care for elderly and very poor. On the other side of United States health care system are its cons. For example one of the main cons of the present U. S. health care system is that Americans pay out a large amount extra for their health care, but the sad fact is, many American citizens are not any healthier than other citizens in other nations that pay out much less in funds for health care. The amount of money paid out on American health care is astounding to say the least. Another major drawback of the U. S. health care system is that a great majority of American citizens are in fact underinsured or worst case scenario, uninsured. Lastly, the United States’ health care system most major cons deal with the lack of health care access, high costs and comprehensive quality health care for everyone requiring health care. A 2007 review of all studies comparing health outcomes in Canada and the U. S. , in a Canadian peer-reviewed medical journal, found that health outcomes may be superior in patients cared for in Canada versus the United States, but differences are not consistent. (Guyatt et. al. , 2007) Life expectancy is longer in Canada, and its infant mortality rate is lower than that of the U. S. but there is debate about the underlying causes of these differences. The World Health Organizations ratings of health care system performance among 191 member nations, published in 2000, ranked Canada 30th and the U. S. 37th, and the overall health of Canadians 35th to the American 72nd. (The World Health Report 2007) Compare and Contrast Government involvement Canadas single-payer health care system is universa l, while in the United States, with its mixed public-private system, 16% are uninsured at any one time. The governments of both nations are closely involved in the delivery of health care. The central structural difference between the two is in health insurance. In Canada, the federal government is committed to providing funding support to its provincial governments for health care expenditures as long as the province in question abides by accessibility guarantees as set out in the Canada Health Act, which explicitly prohibits billing end users for procedures that are covered by Medicare. While some label Canadas system as socialized medicine, the term is controversial. Princeton University health economist Uwe E. Reinhardt says that single-payer systems are not socialized medicine but social insurance systems, because doctors are in the private sector. In the U. S. , direct federal and state government funding of health care needs of its citizens is limited to Medicare, Medicaid, and the State Childrens Health Insurance Program (SCHIP) insurance programs for eligible senior citizens, very poor, disabled persons, and children. One study estimates that about 25 percent of the uninsured in the U. S. are eligible for these programs but unenrolled, but extending coverage to all who are eligible remains a fiscal and political challenge. The federal government also runs the Veterans Administration, which provides care to veterans, their families, and survivors through medical centers and clinics. For everyone else, health insurance must be paid for privately. Just fewer than 60% of U. S. residents have access to health care insurance through employers, although the workers expected contribution to such plans varies widely. Those whose employer does not offer health insurance, as well as those who are self-employed or unemployed, must purchase it on their own. Despite the greater role of private business in the U. S. , federal and state agencies are increasingly involved in U. S. health care spending, paying about 45% of the $2. 2 trillion the nation spent on medical care in 2004. Beyond its direct spending, the U. S. government is also highly involved in health care through regulation and legislation. For example, the Health Maintenance Organization Act of 1973 provided grants and loans to subsidize Health Maintenance Organizations and contained provisions to stimulate their popularity. HMOs had been declining before the law; by 2002 there were 500 such plans enrolling 76 million people. The Canadian system has been 69-75% publicly funded, though a substantial portion of services are provided by private corporations, namely the privately incorporated medical practices of most physicians (however, despite the fact that many doctors will refer to their private clinics, these are in fact merely private corporations that derive nearly all their revenue through government billings). Although some doctors work on a purely fee-for-service basis (usually family physicians), some family physicians and most specialists are paid through a combination of fee-for-service and fixed contracts with hospitals or health service management organizations. Canadas universal health plan does not cover certain services. Non-cosmetic dental care is covered for children up to age 14 in some provinces. Prescription drugs are not covered, but some provinces have drug cost programs that cover most drug costs over a certain portion of a familys income. Drug prices are also regulated, so brand-name prescription drugs are often significantly cheaper than in the U. S. Optometry is only covered in some provinces and is sometimes only covered for children under a certain age. Visits to many specialists may require an additional fee. Also, some procedures are only covered under certain circumstances. For example, circumcision is not covered, and a fee is usually charged when a parent requests the procedure; however, if an infection or medical necessity arises, the procedure would be covered. Coverage and access In Canada, every citizen has coverage, but access can still be a problem. Based on 2003 data from the Canadian Community Health Survey, an estimated 1. 2 million Canadians do not have a regular doctor because they cannot find one, and just over twice that number do not have one because they havent looked. Those without a regular doctor are 3. 5 times more likely to visit an emergency room for treatment. In the U. S. , the federal government does not guarantee universal health care to all its citizens, but publicly funded health care programs help to provide for the elderly, disabled, the poor, and children. The Emergency Medical Treatment and Active Labor Act also ensure public access to emergency services regardless of ability to pay. Wait times One of the major complaints about the Canadian health care system is waiting times, whether for a specialist, major elective surgery, such as hip replacement, or specialized treatments, such as radiation for breast cancer. Studies by the Commonwealth Fund found that 24% of Canadians waited 4 hours or more in the emergency room, vs. 12% in the U. S. ; 57% waited 4 weeks or more to see a specialist, vs. 23% in the U. S. In a 2003 survey of hospital administrators conducted in Canada, the U. S. , and three other countries, 21% of Canadian hospital administrators, but less than 1% of American administrators, said that it would take over three weeks to do a biopsy for possible breast cancer on a 50-year-old woman; 50% of Canadian administrators versus none of their American counterparts said that it would take over six months for a 65-year-old to undergo a routine hip replacement surgery. Yet U. S. administrators were the most negative about their countrys health care system. Hospital executives in all five countries expressed concerns about staffing shortages and emergency department waiting times and quality. In the U. S. , patients on Medicaid, the low-income government programs, can wait three months or more to see specialists. Because Medicaid payments are so low, doctors dont want to see Medicaid patients. In Benton Harbor, Michigan, specialists agreed to spend one afternoon every week or two at a Medicaid clinic, which meant that Medicaid patients had to make appointments not at the doctors office, but at the clinic, where appointments had to be booked months in advance. Price of health care Health care is one of the most expensive items of both nations’ budgets. The U. S. government spends more per capita on health care than the government does in Canada. In 2004, the government of Canada spent $2,120 (in US dollars) per person on health care, while the United States government spent $2,724. However, U. S. government spending covers less than half of all health care costs. Private spending for health care is also far greater in the U. S. than in Canada. In Canada, an average of $917 was spent annually by individuals or private insurance companies for health care, including dental, eye care, and drugs. In the U. S. , this number is $3,372. In 2004, health care consumed 15. 4% of U. S. annual GDP. In Canada, only 9. 8% of GDP was spent on health care. This difference is a relatively recent development. In 1971 the nations were much closer, with Canada spending 7. 1% of GDP on health while the U. S. spent 7. 6%. The health share of gross domestic product (GDP) in America is expected to hold steady in 2006 before resuming its historical upward trend, reaching 19. 6 percent of GDP by 2016. The mixed system in the United States has become more similar to the Canadian system. In recent decades, managed care has become prevalent in the United States, with some 90% of privately insured Americans belonging to plans with some form of managed care. Managed care is when the insurance company controls patients health care to reduce costs, for instance by demanding a second opinion prior to any expensive treatment. Administrative costs for health care are higher in the United States than in Canada. Medical professionals Some of the extra money spent in the United States goes to doctors, nurses, and other medical professionals, all of whom receive higher compensation than their counterparts north of the border. According to health data collected by the OECD, average income for physicians in the United States in 1996 was nearly twice that for physicians in Canada. Canada has fewer doctors per capita than the United States. In the U. S, there were 2. 4 doctors per 1,000 people in 2005; in Canada, there were 2. 2. Some doctors leave Canada to pursue career goals or higher pay in the U. S. Many Canadian physicians and new medical graduates also go to the U. S. for post-graduate training in medical residencies. Often new and cutting-edge sub-specialties are more widely available in the U. S. as opposed to Canada. However, statistics published in 2005 by the Canadian Institute for Health Information (CIHI), show that, for the first time since 1969 (the period for which data are available), more physicians returned to Canada than moved abroad. Drugs Both Canada and the United States have limited programs to provide prescription drugs to those in need. In the United States the introduction of Medicare Part D has extended partial coverage for pharmaceuticals to Medicare beneficiaries. In Canada all drugs given in hospitals fall under Medicare, but other prescriptions do not. The provinces all have some programs to help the poor and seniors have access to drugs, but while there have been calls to create one, no national program exists. About two thirds of Canadians have private prescription drug coverage, mostly through their employers. In both countries there is a significant population not fully covered by these programs. A 2005 study found that 20% of Canadas and 40% of Americas sicker adults did not fulfill a prescription because of cost. One of the most important differences between the two countries is the much higher cost of drugs in the United States. In the United States $728 per capita is spent each year on drugs, while in Canada it is $509. At the same time consumption is higher in Canada, with about 12 prescriptions being filled per person each year in Canada and 10. 6 in the United States. The main difference is that patented drug prices in Canada average between 35% and 45% lower than in the United States. The price differential for brand-name drugs between the two countries has led Americans to purchase pward of US$1 billion in drugs per year from Canadian pharmacies. Technology The United States spends more on technology than Canada. The study Medical Imaging in Canada, 2004 reported that in 2004, Canada had 4. 6 MRI scanners per million population while the United States had 19. 5 per million. Canadas 10. 3 CT scanners per million also ranked behind the United States, which had 29. 5 per million. Malpract ice litigation The extra cost of malpractice lawsuits accounts for some of the difference in health spending in the two countries. In Canada the total cost of settlements, legal fees, and insurance comes to $4 per person each year, but in the United States it is $16. Average payouts to American plaintiffs were $265,103, while payouts to Canadian plaintiffs were somewhat higher, averaging $309,417. However, malpractice suits are far more common in the U. S. , with 350% more suits filed each year per person. While malpractice costs are significantly higher in the U. S. , they make up only a small proportion of total medical spending. The total cost of defending and settling malpractice lawsuits in the U. S. n 2001 was approximately $6. 5bn, or 0. 46% of total health spending. Critics say that defensive medicine consumes up to 9% of American healthcare expenses. In the same year in Canada, the total burden of malpractice suits was $237 million, or 0. 27% of total health spending. Ancillary expenses There are a number of ancillary costs that are higher in the U. S. Administrative costs are significantly higher in th e U. S. ; government mandates on record keeping and the diversity of insurers, plans and administrative layers involved in every transaction result in greater administrative effort. One recent study comparing administrative costs in the two countries found that these costs in the U. S. are roughly double what they are in Canada. Another ancillary cost is marketing both by insurance companies and health care providers. These costs are relatively higher in the U. S. , contributing to higher overall costs in that nation. Health care outcomes In 2007, Gordon H. Guyatt et al. conducted a meta-analysis, or systematic review, of all studies that compared health outcomes for similar conditions in Canada and the U.S. , in Open Medicine, an open-access peer-reviewed Canadian medical journal. They concluded, Available studies suggest that health outcomes may be superior in patients cared for in Canada versus the United States, but differences are not consistent. Guyatt identified 38 studies addressing conditions including cancer, coronary artery disease, chronic medical illnesses and surgical procedures. Of 10 studies with the strongest statistical validity, 5 favored Can ada, 2 favored the United States, and 3 were equivalent or mixed. Of 28 weaker studies, 9 favored Canada, 3 favored the United States, and 16 were equivalent or mixed. Overall, results for mortality favored Canada with a 5% advantage, but the results were weak and varied. The only consistent pattern was that Canadian patients fared better in kidney failure. Canadians are, overall, statistically healthier than Americans and show lower rates of many diseases such as various forms of cancer. On the other hand, evidence suggests that with respect to some illnesses (such as breast cancer), those who do get sick have a higher rate of cure in the U. S. than in Canada. In terms of population health, life expectancy in 2006 was about two and a half years longer in Canada, with Canadians living to an average of 79. 9 years and Americans 77. 5 years. Infant and child mortality rates are also higher in the U. S. Some comparisons suggest that the American system underperforms Canadas system as well as those of other industrialized nations with universal coverage. For example, a ranking by the World Health Organization of health care system performance among 191 member nations, published in 2000, ranked Canada 30th and the U. S. 7th, and the overall health of Canada 35th to the American 72nd The Positive Aspects of the United States Healthcare System. United States have lower cancer mortality rates than Canadians. Breast cancer mortality is 9% higher, prostate cancer is 184% higher and colon cancer mortality for males is 10% higher in comparison with the United States. United States have a higher ground gateway to chronic diseases trea tment than patients in other developed countries. For example: 56% of United States patients are beneficiaries of statins to reduce cholesterol levels and heart disease protection. United States has improved access to preventive cancer screening than Canadians. Proportionally to the age/population groups who had consigned from prescribed tests for cervical, prostate, breast and colon cancer: * 89% of middle aged American women had received a mammography in comparison to less than 72% of Canadians. * 96% of American women had received a pap smear, in comparison to less than 90% of Canadians. * 54% of American males have received a PSA test, in comparison to less than 16% Canadians. * 30% of Americans have received a colonoscopy, in comparison of the 5% of Canadians. Lower income Americans are in better health than comparable Canadians. American senior citizens with incomes under the median are reported as having excellent health in contrast with Canadian seniors 11. 7% vs. 5. 8%. Americans spend less time waiting for care than patients in Canada. Canadian patients have waited the double time lapse to go to a specialist to receive these types of healthcare services for example: radiation therapy or surgery replacements. Approximately 827,429 Canadians are on waiting lists for medical procedures. People in countries with more government control of health care are highly dissatisfied and believe reform is needed. 70 percent or more citizens from Canada, Germany, Australia, etc. , adults think that their health system needs to be reform. On recent satisfaction polls Americans are more satisfied with their healthcare than Canadians. When Americans were asked about their healthcare not their healthcare system 51. 3% were satisfied in comparison to a 41. 5% of Canadians the dissatisfaction level was 6. 8% for Americans and 8. 5% to Canadians. Americans have easier access to new medical technologies than patients in Canada. American health specialists have concluded that (MRI) magnetic resonance imaging and (CT) computerized tomography are the major helpers to improve patient well-being. The United States account for CT’s is 34 scanners per million Americans, in comparison of 12 per Canadians. For MRI’s the count is 27 machines per million Americans in contrast of 6 per million of Canadians. American medical facilities are responsible for almost all the health care discoveries and technologies. U. S. ospitals have conducted more clinical research than any other country. Since the 1970s, the Nobel Prize in medicine or physiology has been awarded to American recipients. The Negative Aspects of the United States Healthcare System First, is the U. S. A’s health care system productively efficient relative to Canada’s health care system? Second, is the U. S. A. ’s problem of rising health care costs a particular concern? Although no country can claim to have eliminated inefficiency, the US’s high costs stand out. Thirdly, what effect does the U. S. A. ’s uninsured have on the Health Care system? Lastly, how does the restriction in choice of health care effect the USA? U. S. A. ’s Health Care’s Rising Costs Healthcare costs will continue to increase in the foreseeable future. Americans are dissatisfied with their health care system (Schoen, et. al. , 2007) but also spend more than the citizens of other countries. Other countries negotiate very aggressively with the providers and set rates that are much lower than we do. In America, Medicare and Medicaid negotiate prices on behalf of their tens of millions of members and, not coincidentally, purchase care at a substantial markdown from the commercial average. But outside that, it’s a free-for-all. Providers largely charge what they can get away with, often offering different prices to different insurers, and an even higher price to the uninsured. â€Å"Organizations of all sizes can embrace to take advantage of the rapid changes that our healthcare system will likely deliver in the next few years by positioning the organization to take a â€Å"proactive† approach to rising health care costs. So who’s to blame: Drug companies, insurers, politicians, lawyers, and the bad habits of Americans all figure into high and rising health-care costs? But the biggest contributors to high costs—doctors and hospitals—get off easier among consumers, our survey found. Sellers of healthcare services in America have considerable power to set prices, and so they set them quite high and they set them with margins as high as almost 20 percent. Unfortunately, the 2010 health-reform law does little to directly address prices. It includes provisions forcing hospitals to publish their prices, which ultimately would bring more transparency to this issue. † (Miller, 2008) Consequently, when all is said and done, health is a business in the United States. Restriction in Choice of Health Care One aspect of the USA’s Health Care system is that today’s employer-based insurance system restricts individuals’ choice of insurance, and many people are locked into jobs for fear of losing coverage. In the early 1990s, when insurers tried to reinvent themselves by embracing managed care, health insurers and employers sought to sharply limit patients’ choice in health care providers. Instead of just paying doctor and hospital bills, insurers also assumed a greater role in their customers’ medical care by restricting what specialists they could see or which hospitals they could go to. The issue of health care freedom is not discussed much in the debate over health care policy. Unfortunately, most policymakers prefer that government tell health care consumers what they can purchase and what treatments they can receive. Most do not favor greater health care freedom, which means the health care consumer is paramount, not a government bureaucrat or politician. Health Care’s Uninsured â€Å"A record rise in the number of people without health insurance across the nation is fueling renewed debate over a health care law that could work better at boosting coverage than controlling costs.

Conflict Mode Assessment

Conflict Mode Assessment Introduction A conflict is a form of disagreement between parties leading to a confrontation. This arises in most cases due to people’s difference in ideology or lack of mutual interest in a certain activity.Advertising We will write a custom essay sample on Conflict Mode Assessment specifically for you for only $16.05 $11/page Learn More Settlement of conflicts has to take place amicably in order to play down the harmful impacts that they may cause in an organization (Jellison, 2006). The paper highlights conflict using a â€Å"job interview† scenario, where the person is supposed to solve a conflict arising due to unexpected challenges. Convectional wisdom is an essential requirement when solving conflicts of any magnitude to ensure sustainable relationships regardless of change. The Thomas Kilman conflict model consists of five modes used when managing conflicts and changes. It based on human behaviors of assertiveness or cooperativeness as a form of action in adjusting to changes caused by conflicts. Competing being the first mode, involves assertiveness and self-centered actions when handling conflicts. The intention is to use all channels available to triumph in a scenario. It can engage individual using their rights in obtaining power of control in a situation. This action has a score of five in a continuum (Jellison, 2006). Accommodating is not assertive, contrary to competing, the next party is considered in a conflict. It engages another’s point of view, normally awarded a score of nine in a continuum.Advertising Looking for essay on psychology? Let's see if we can help you! Get your first paper with 15% OFF Learn More Avoiding, which is the third mode, also has a score of five is not assertive and is usually uncooperative. A conflict to be solved is neglected in this case either temporary or permanently. Collaborative is a mutual mode of solving conflicts where both party’s interests are looked into (Jellison, 2006). It involves self-sacrifices where necessary when handling issues analytically, normally given a score of five, which translates to 40% using percentage. Lastly, compromise is an intermediary form of conflict management, the agreement made satisfies both parties. Compromise addresses issues directly and is normally in a score of six. Compromising mode is the preferred style of conflict management in the scenario above. There has to be mutual agreement amidst the parties involved due to unexpected situations. The interview is of much benefit to one party while solving the accident is beneficial to all. An understanding might result to a solution that benefits all the parties using compromising mode. It is only by the compromising mode of conflict management that a win-win situation is possible (Jellison, 2006). Compromising model minimizes the chances of conflict aggravating, since there can be a clash of interest amidst two parties. This m ode is suitable in solving problems of dynamic nature when under pressure. This mode allows for exploration of other channels when settling disputes, normally preferred in cases of emergency. Compromise reduces the sensitive nature of a problem at hand in this case the interview is of much importance than parking the car.Advertising We will write a custom essay sample on Conflict Mode Assessment specifically for you for only $16.05 $11/page Learn More For the competing mode, there will be assertiveness in insisting on the right to parking. This overlooks other people’s interests. Collaborating mode will involve integrating the interests of the other party. It will delve much into issues thus complicating the conflict auxiliary from the initial intention. Avoiding the conflict does not apply in this case since it will provide no solution when managing conflicts. Avoiding is suitable when the issue at hand is of a smaller magnitude, thus negligible (Je llison, 2006). Accommodating will result to less solution for urgent cases requiring immediate solutions while benefits is to the other party more than self. Competing mode is difficult to work with, since a good number of conflicts results from competition between parties. This mode generates unpopular decisions when sorting out problems and it is more self-centered limiting other people’s opinions that might be useful in the end. This conflict mode is only useful in groups that uphold integrity and high values when conducting operations. It is much dependent on an individual as opposed to other models in handling conflicts.

This role in National Velvet landed her other subsequent, but perhaps less notable roles, until she filmed Cleopatra, which rocketed her to cult star status. According to Royster (2003), â€Å"Indeed, for the rest of her life, Elizabeth Taylor tended most often to apply the excessive blue eyelid makeup designed for Cleopatra† (pp. 225). What Ms. Taylor is also known for is her elaborate relationships. According to the biographical news article â€Å"Elizabeth Taylor: News Stories About Elizabeth Taylor† (2011), â€Å"During her 79 years, Elizabeth Taylor appeared in more than 50 films, won two Oscars, and was married eight times to seven men† (pp. 1). Ms. Taylor also had several romances. According to the Elizabeth Taylor Biography article (2011), â€Å"Elizabeth's marital affairs have been a target of many tabloids† (pp. 1). Ms. Taylor did much charitable work. According to the article â€Å"In Loving Memory of Dame Elizabeth Taylor† (2011), she worked tirelessly for raising charitable donations to AIDS victims, gaining more federal funding for AIDS research (pgh. 4). Until her death, she was always supporting her various causes. As stated in Elizabeth Taylor’s Charity Work, Events, and Causes (2011), Ms. Taylor also worked to ensure the ethical treatment of animals by supporting the foundation entitled Dogs Deserve Better (pgh. 1). Certainly, Ms. Taylor was a woman of remarkable talents with assets to further her causes—which were extensions of her graceful and compassionate heart. Hopefully others will follow her example. An Analysis of Liz Taylor’s Behavior, Personality Traits and Observations About Feelings, Values, and Social Relationships Ms. Taylor’s behavior, personality traits, and some observations about her feelings, values, and social relationships will be discussed here. Ms. Taylor was never much of a â€Å"drama queen†Ã¢â‚¬â€except when it came to acting as well as personal life. She was not a standoffish person, but rather was a warm and kind individual thrust into the spotlight of fame perhaps a bit early. However, Ms. Taylor handled all of her interactions with grace and beauty. Even in her declining years, when she no longer could walk by herself, Ms. Taylor radiated a certain glow about her that was unmistakable. One of Ms. Taylor’s personality traits included the fact that she was a serial monogamist—at least, when she wasn’t having an extramarital affair. Why is it that under the long shadow cast by â€Å"old† studio Hollywood, such behavior was tolerated? Liz Taylor was indeed a beautiful woman, but what may have compelled her to get involved in such destructive relationships? Of course, no one can really entirely map out the reasons why someone would engage in romances on the side, but i t may have spoken to Ms. Taylor because—even though she was very rich—she was continually dissatisfied with what she had or who she was with seemingly many times. Having been married eight times, it seems that she would have been a very fickle wife. Perhaps it could be attributed to her vanity, but perhaps there is also a deeper meaning behind those divorces—that she was seeking something that she could not find in one man alone—

Trace character vs. fate theme Essay Example | Topics and Well Written Essays - 1500 words

Trace character vs. fate theme - Essay Example Nevertheless ancient civilizations of Europe: Greece and Rome had presented new outlooks, new philosophies and ethics which were based on humanism and materialism. Ancient Greek philosophers and dramaturges had presented a new, liberal and unique idea of human's place in the universe. It was a human-centered philosophy, based on ration, sensualism and freedom of thought. Plato's Allegory of the Cave has become classical example which presents the world we live in: "Behold! Human beings living in an underground cave, which has a mouth open towards the light and reaching all along the cave; here they have been from their childhood, and have their legs and necks chained so that they cannot move, and can only see before them, being prevented by the chains from turning round their heads. Above and behind them a fire is blazing at a distance, and between the fire and the prisoners there is a raised way; and you will see, if you look, a low wall built along the way, like the screen which marionette players have in front of them, over which they show the puppets." (Plato, 2000, p.297) Allegory of the Cave is a symbolic name as it implies that human's world is not a world of darkness, where there is no way out, where everything is preplanned and where everyone has his own fate. The word "cave" means that there exists a way out, and this way is will power, confidence and knowledge based on rationalism of enquiring mind. There exists a sun at the end of cave, and sun of knowledge and reason shines for everyone and creates harmony, confidence and promotes social progress. The freedom-loving and democratic spirit of Plato's works and of Allegory of the Cave in particular case witnesses about original and new philosophy of human-centered universe, where the fate meant nothing but a cave or prison, as it was only a "prison" of human's will and mind. Plato stated that: "the man who truly worships the stars does not need to enquire what fate they weave for him, he is lifted above the reach of fate in his communion. By becoming one with the stars, he becomes one with his own fate." (Plato, 2000,p.194) Plato continues his discourses about human will, human nature, feelings and reason in his another work The Symposium which is written in the form of dialogue (like "the allegory") of several prominent citizens of Athens: dramaturges and philosophers. The theme of conversation is love, a very contradictory theme and very subjective. Nevertheless The Symposium remains to be a classical reference for study of this theme. As every participant in the dialogue presents his own point of view, presents his arguments, myths and discourses about love, we see the diverse ethic atmosphere in Ancient Greece, such triumph of human reason and ethical thought. Through logical and exhaustive discourses about love in the dialogue of famous Greeks we observe the power of subjective thinking and power of speech through arguments. It's a dialogue of people who are confident in their ethical principles and are confident that they are able to change something in the surrounding word. Their speeches do not contain elements of mysticism in the volume we can find in works of earlier authors such as Homer for example, their

Obsessive Compulsive Disorder Research Paper Example | Topics and Well Written Essays - 1750 words

Obsessive Compulsive Disorder - Research Paper Example Worried that she might have an allergic attack, she cleans the house every couple of hours, never seemed to be satisfied that she did it right two hours ago. This action continues throughout the day, leaving little or no room for her other activities that are equally essential (Mayo Clinic Staff). Typically, obsessive compulsive disorder makes a person go through repeated actions that mainly originates from having distressing thoughts. These thoughts make the individual do or perform a certain action that is done over and over again in order to pacify the stress and anxiety that he or she is feeling (NIH: National Institute of Mental Health). The obsessions which come about constantly are often unreasonable, quite disturbing and in fact have no actual basis. The individual who suffers from obsessive compulsive disorder eventually realizes that the obsessive feeling and thoughts he or she is currently having distorts reality; and they feel incapable to control them because they go thr ough the same motions again and again (Mental Health America). Trying to stop or ignore the obsessions only heightens the feelings of apprehension and distress; while doing rituals or compulsions give short-term relief from the stress and discomfort brought about by having obsessions. Unfortunately, having obsessive compulsive disorder upsets a person’s daily living schedules and activities because the obsessions and subsequent compulsions makes it hard to concentrate in doing the normal activities which the person was accustomed to. The rituals or repetitive actions takes hours to do, sometimes the whole day making it quite impossible for the individual with obsessive compulsive disorder little time to do something more productive. If obsessive compulsive disorder is not properly addressed overtime, it can have a negative impact on all the aspects of a person’s life (The Anxiety Disorders Association of America (ADAA)). The theoretical causes of obsessive compulsive d isorder are biology, environment and inadequate seratonin. These causes are considered to be hypothetical since the true or actual cause of obsessive compulsive disorder is not fully known (Mayo Clinic Staff). Biology pertains to the study of plants and animals, which includes the normal chemistry and role of the brain in relation to the other parts of the body. It is contemplated by researchers that obsessive compulsive disorder is an end result of an irregular change in the normal working condition of the brain circuits, which may be due to an inadequate level of serotonin, a chemical messenger within the brain (Mayo Clinic Staff). The insufficient amount of such brain chemical affects the normal communication of brain parts that ultimately gives rise to the occurrence of obsessive compulsive disorder (Mental Health America). The environment is also said to contribute in the occurrence of obsessive compulsive disorder because of some behavior-related habits, which were acquired du ring the growing and developmental phase of a particular individual (Mayo Clinic Staff). The habits are generally inculcated from childhood to early teens where various factors that stem out of one’s surroundings are easily assimilated and are considered normal even if they are not within the norm or are socially unacceptable. Obsessive compulsiv

Key Elements Of Information System Information Technology Essay

Key Elements Of Information System Information Technology Essay The task has been assigned to me by my college which is the ABP awarding body certification requirement. I have completed the assignment after a thorough study of various sources such as books, journals and websites. OBJECTIVES: Describe the concept of Information Based System in organization. Describe how Information System works in organization. Describe the various types of Information Systems by breath of support. Identify the major Informational Systems that support each organisational level. Literature Review: 1) Information: Any raw data that is organized and verified to be accurate and timely for any purpose and presented within a context that gave it meaning and relevance and it leads to increase in understanding and decrease uncertainty. 1.1) Information System: When people utilize information or organizations by using technologies gather, process, store, use and disseminate information uses. Information System (IS) is a system that gave the information necessary for managers and management to run an organization effectively. IS and the information it gives are essential components of reasonable business decisions. Information industries help in providing growth in most economies of business. Every organization achieved it success on the bases of there information system. Due to change in technology and globalization of markets many industries are now trying to develop and improve there information system because they emphasizes on there information. Information system is not just a computer system but information and communication technology play a vital role in helping the organization to fulfill it needs. Information system refers to the system of people, data and activities both computer-based and manual that effectively gathers, process store and disseminate organization information. It is important to maintain the information system in organization and adopt new approaches for improvement in the development, use and reviews of IS system with in the organization must be an ongoing process of both bank management and OCC examiners. Every IS have clearly defined framework of guidelines, procedures policies and standards for different organizations. It should be fallowed by any organization for the development of its system and also to maintain and use all information where it necessary. Information System is used and viewed by all Management Levels. It helps the organization and supports them in long term strategic goals and objectives. It helps in financial accounting systems that are used to maintained control on all financial record keeping activities. Every organization should designed there Information System to achieve the following goals. Improve communication among employees. Deliver all complex and important material through out the institution. Provide a system for recording and processing information. Reduce all expanses related to labor, material and other activities. Help in achieving organization strategic goals and objective and provide direction. Organization a) Customers b) Retailers c) Employers Technology Websites Internets Collaborative Planning softwareà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s Management a) Develop growth b) Strategy c) Monitor services d) Level and cost Information System a) Customize Products b) Interact with customer c) Exchange ideas and reports d) Coordinate production with sales Business Solutions Increase customer services Increase revenues Reduce cost Business Challenges Mature Industry Inefficient Process Information System provides help and facts for decision making which support and improves overall decision making process. Information System also improves job performance through out the organization. It also provides help to all level of management. It gives the data and information and helps the management in making strategic decisions. It helps the organization in all activities to monitor, control and distributes information to all employees, customers. Effective Information system gives up-to-date presentation formats and time frames required by all management levels. Information System can be maintained manual or automated or both combine. Effective deliveries of an organization products and services are supported by Information system. These systems be accessible and used at all level of management and organization. Information System is also helpful in over all risk management strategy. Information system also help the organization to keep control, measure, monitor, recognize and manages all the activates, risk and Limits. Risk Management has four key elements. Policies or practices. Operational Processes Staff Management. Feed back Devices. Information system should be both operational and informational. So that management can use it to measure performance, manage resources and help organization with regulatory requirements. Information system also used to provide effective risk control which helps to maintain proper management and minimize risk through the organization. it also help the organization to make new policies help in practicing these policies provide up to date information in all operational process also help in making assignments duties and responsibilities for staff and managers. Data used in organization come from many finical records and transaction systems and proper control procedures must be setup to help in gathering relevant data and also help in correction of data. Information system organized and the data is gathered from different equipments i.e mainframes, microcomputer, minicomputer. Processing control help the system on smaller computer and pre defined and also effective as those commonly found on the larger mainframe system. The OCC fully endorses and supports placing these principles in writing to improve effective communications throughout the organization. Improving Weakness of Information System Risk. 1.2) Key Elements of Information System: To work properly and effectively the five key elements should be checked and functioned are: time lines, accuracy, consistency, completeness and relevance. Timeliness: Information system should be capable of providing distributing information to right users. Information system is capable of providing short and long reports of information. Information system also helps in processing, collecting and producing results from data. It also help in making correction, adjustments in errors found in data. Accuracy: Information System provides control checks in editing balancing. All the external internal audit programs done by organization provides the adequacy of internal control. Consistency: All the data should be process consistently and uniformly. Variations in data be collected and reported to information analyst. Because data collection and reporting process change over time management must establish procedures to allow systems changes. All the procedures should be documented, willdefind and clearly communicated to all related employees and should include proper effective monitoring system. Completeness: All the data and information provided by information system to management level should be complete and checked by all accepts. Relevance: All the information must be relevant to organization objectives and strategies. Information that is unnecessary or too detailed should be sorted out. 2) Information System as Bridge: Information system provides us bridge between management information science and computer science. Computer science provides information technology software. Information system brings all human activities and information technology to one place and it provides communication link between these two worlds. The system well serves the people and organization by using all the IT capabilities. To run this system properly it requires specialist people having knowledge of both computer world and organization and the people who using these systems. All the system should work with in the contexts of organization, management and the information society. To build a bridge like this between the information organization and people we need skills in programming, computer architecture and networks. Also we need techniques for information system analysis design by using all advance data base design methods and related professional and legal knowledge. 3) Level Types of Information Systems: Every business has different information system needs. It also depends upon different levels in organization. Three key information systems are Transaction processing system Management Information System Decision Support Systems The importance of information is different on different level of management. The information can categorise as strategic, managerial and operational information. The information used by senior management for decision making is Strategic information. The lower levels in the organization do not require this information. The information systems that gave information for decision is known as Decision Support Systems. Figure Relation of information systems to levels of organization The information used by the middle line of management is known as managerial information. The information used by middle line management help in making short-term decisions and plans for the organization. Information likes sales analysis or production details for the whole year. Information system is now days the necessity of all organizations to fulfil all the managerial activates. Due to its Importance, most of the big organizations have separate IS departments. Whose duty is to watch the use and proper functioning of the system. For daily and short term information we need third level of information. It help the operational level to carry out day to day operational activates. it also help in attendance record of employees. Information System gives information for processing transaction of the organization, that type of information system is known as Transaction Processing System or Data Processing System. For example information provided by such systems are processing of orders, evaluating overdue purchaser orders of marketing and sales departments.. 3. a) Transaction Processing Systems: Transaction Processing System the organization in there business transaction process. Any activity of the organizations can be called Transaction. Every organization has different transaction. For example, take a airline reservation system. Booking, cancelling, etc are all transactions. However, there are some transactions, which are common to almost all organizations. These include calculation, storage and retrieval. Speed and accuracy, can be achieved by TPS and can be programmed to follow routines functions of the organization. 3. b) Information System: Management takes help in solving problems and making decisions from it. They use transaction processing information and all relevant information also. It process queries as quickly as they arrive. An important element of IS is database. A database is a collection of data items that can be processed through application programs and available to many users. 3. c) Decision Support System: These systems help senior management in making long term decisions. With the help of this systems we can handle unstructured or semi structured both decisions. A decision will be unstructured if there are no clear procedures for making the decision. A decision support system must be easy to operate and also it should be flexible for all users so that they can produce reports by giving data and it should be format according to the situation explained. 4) Level of Management System: 4 .a) Operational-level Management System: This system helps the operational managers by keeping track of the all necessary activities and transactions of the organization. This system is answerable for the routine questions. It provides help in sales, receipts, cash deposits, payroll, credit decisions, and flow of materials. 4 .b) Knowledge-level Management System: Support knowledge and data workers in an organisation. The reason of these systems is to help the organisation discover, organise and integrate new and existing knowledge in to the business, and to help control the flow of paperwork. These systems, especially in the form of collaboration tools, workstations, and office systems, are the fastest growing applications in business today. 4 .c) Management-level Systems: At this level it helps in monitoring, controlling, decision-making, and administrative activities of middle managers. We can get periodic reports rather then information on operation. it also helps in non-routine decision-making, focusing on less-structured decisions for which information requirements are not always clear. 4 .d) Strategic-level Management System: Help senior management how to keep control and tack actions on strategic issues and long-term trends, wither it in the organization or related to external environment. Main reason is to use organisational capability with the changes, and opportunities, occurring in the medium to long term in the external environment. An organisation must have operational, knowledge, management and strategic level systems for each functional area within the organisation. This would be based on the management model adopted by the organisation, so, while the most commonly-adopted systems structure would simply follow the standard functional model, structures reflecting bureaucratic, product and matrix models are also possible. As identified before, enterprise level information systems attempt to encompass the whole organisation in one system.

Primarily involved in information use, manipulation or dissemination. Typical OAS handle and manage documents, scheduling and communication. Knowledge Work Systems: Targeted at meeting the knowledge needs of knowledge workers within the organisation In general, knowledge workers hold degree-level professional qualifications (e.g. engineers, scientists, lawyers), their jobs consist primarily in creating new information and knowledge 5 .c) Management-level Systems Management Information Systems: Typically these systems focus entirely on internal events, providing the information for short-term planning and decision making. MIS summarise and report on the basic operations of the organisation, dependent on the underlying TPS for their data.

Ticket less travel Automation with IT Reduced costs Improved service Air Asia developed open skies software to automate ticket handling to Avoids travel agents and their fees Uses reservation agents who work from home using VoIP Encourages internet flight booking by customers Maintenance information system used to log airplane parts and time cycles for replacement Air Asia used innovative technique for routing airplanes Does not use hub and spokes method only point to point. Takes most profitable route between cities. Keeping flight manuals on laptop computers allows for paperless cockpits. Saves pre-flight time associated with calculating weight of plane (annual savings of 4800 hours). Information System Helps Air Asia offer Better Services. Safety First: Partnering with worldà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s most renowned maintenance providers and complying with the world airline operations. High Aircraft Utilization: Implementing the regions fastest turn around time at only 25 minutes, assuring lower costs and higher productivity. Low Fare, No Frills: Providing guests with the choice of customizing services without compromising on quality and services. Streamline operations: Making sure that processes are as simple as possible. Point-to-Point Network: Applying the point-to-point network keeps operations simple and cost low. 7) Conclusions: Every organization run on it strategies. And strategies make by management on the basis of the information they have. So I think if the organization have strong information system and it have up-to-date information then the strategies which they are going to make for future will be perfect and it will gave the organization competitive edge in market and on it competitors

The whitlam government Essay -- essays research papers

The Whitlam Government (1972 – 1975) introduced many ideas that impacted on all the people of Australia. There may have been impediments that prevented the Whitlam Government from introducing new ideas, such as the Senate. Nevertheless in three years the Whitlam Government managed to win the hearts of many Australians. In their three year reign the Whitlam Government managed to create Medibank, establish firm relations with People’s Republic of China, establish the Department of Aboriginal Affairs (Giving all Aboriginals a ‘voice’), obtained responsibility for tertiary education over from the states and eradicated tertiary fees, and establishing Supporting Mother’s Benefit’s. These were only a few of their achievements. Gough Whitlam had previously seen and heard of the Medical health scheme systems based at U.K. which he favoured. The constitution was the barrier to introducing a health scheme in Australia, and the civil conscription clause. Medibank and other health schemes were designed to avoid civil conscription and provide healthcare service based on Government finance. Whitlam’s aim in creating this system was to break the connection between healthcare and money. Whitlam wanted to break free from the hindrance of money; he wanted healthcare system based on health needs of people rather than the importance of money requirements. In 1972, the introduction of universal health insurance system known as Medibank (now Medicare) was born. It provided significant benefits to the population of Australia who had previously not been able to afford sufficient medical care; it declined private medicine and commenced to pay 85% of medical and hospital fees. Medibank provided inexpensive treatment by hospitals and doctors to all permanent citizens of Australia. Medicare is publicly funded tax surcharge that comes under the title of Medicare levy which add to the scheme. People with low income are excluded which follows a good example. People earning a high income pay a higher tax therefore compensating the loss of low paid workers. Medibank made a vast impact on all the Australian society, as now many people could afford sufficient medical care chiefly people who were still tormented from poverty. The disadvantages might to some people be that the higher they earn the more they have to pay in tax for the Medicare levy. The Whitlam Government had established a... ... of the House of Representatives or a double dissolution and the only way possible for that to happen, was by the dismissal of Whitlam and his colleagues. Opposition parties of Whitlam had affirmed they would only pass the bill only if Whitlam called an election for the House of Representatives. This could not be agreed upon, so a double dissolution (simultaneous election for all members in both houses) had to be called. Kerr could have appropriately notified Malcolm Fraser that the recurrent postponement of Supply had shaped and unbearable constitutional crisis and that the first steps could be taken to determine it if Fraser would choose one of the two alternatives. These were to instruct supporters in the Senate to pass Appropriation bills, or to reject Supply outright. The first option would have resolved the crisis; the second would have left Kerr to seek further advice from responsible ministers. Also, Kerr could have arranged Whitlam a half-senate election, so long as the basic services of government would not subside and that Whitlam take notice of the effect of the election if it did not determine the crisis. These both alternatives were open to Governor General Kerr.

Discrimination Due to Racism

THEME: DISCRIMINATION due to RACISM The scars of discrimination on society as a whole and people as individuals. Discrimination has caused a lot of sufferings on our people and ancestors in many ways around the world which scars lives of people from generation to generation as well as affects individuals and society as a whole.I have chosen a range of societies by selecting the texts, Dawn Raids play-script written by Oscar Knightley, Freedom Writer movie directed by Richard LaGravenese, Othello play-script written by William Shakespeare, Black Like Me novel based on a true story written and experienced by John Howard Griffin and The Untold Story of Emmett Louis Till told by his mother, Uncles and cousins presented by Top Documentary Films. These texts explore a wide range of societies including Black Americans, White Americans, Africans, Pacific Islanders, New Zealanders, Asians, Latinos and other cultures too.These texts help reveal how discrimination scars society and people as in dividuals. What do we see in the text that portrays discrimination? As depicted in the play script Dawn Raids, we are introduced to some racist polices in New Zealand who stopped brown people on the streets asking them for passports in search of over stayers. These racist polices only picked on brown faces that they assumed were Samoans, Tongans, or Fijians. They even stopped Maoris asking them what country they’re from, being treated like over stayers in their own country.There were Europeans and Asians who were over stayers but polices never bothered them to ask for passports. Polices would crash into Pacific people’s houses early in the morning chasing them with dogs frightening their children, families and their neighbours. They were humiliated and embarrassed in front of their neighbours, their children and worst of all they were being treated badly in their own home. This racist act resulted in most Pacific Islanders were being separated and deported back to thei r Islands in a very cruel manner due to their racist hatred towards the Pacific Islanders.This shows that racism humiliates people and affects them in so many ways and discrimination should be stopped. This type of hatred towards other races is also obvious in the movie Freedom Writer but with more races involved, where Latinos, Asians, Black Americans and white Americans are separated into gangs and are targeted by racist white polices. The gangs hate each other due to their races and backgrounds but the one seemed lower than everyone else is the black people. White racist polices pinned down Marcus for a crime he did not commit due to his skin colour being black. I sat there until the police came. But when they come, all they see is a dead body, a gun, and a nigger†. He wasted months of his life locked up in a cell for crime he did not commit but being black put him as the killer and so someone had to pay the price. It shows in this text, justice meant someone had to pay the price and â€Å"someone† meant anyone who is not white. White polices didn’t care who committed the crime because all they wanted was someone to blame and Marcus was the one black guy that was around and due to his race and skin colour being black he was an easy target to pin the crime on.This text shows that racism ruled over justice and how discrimination can destroy one’s life forever. Another text which shows clinging to the belief of discrimination due to racism scars society and people is Othello, where Iago a jealous white man used racism slurs when he awakens Brabantio with the news that his daughter Desdemona, a white young lady has eloped with Othello. He used animal imagery in his racist diatribe against Othello, which is grounded in the idea that black –men and woman—is inhuman. â€Å"Even now, very now, an old black ram is tupping your white ewe. Arise!Arise; awake the snorting citizens with the bell. Or else the devil will make a gr andsire of you. Arise I say. † Iago refers to Othello as an â€Å"old black ram† and is â€Å"tupping† Brabantio’s â€Å"white ewe† Desdemona. He plays on the Elizabeth notions that black men have an animal like hyper-sexuality. This seems geared at manipulating Brabantio’s fears of miscegenation, between Othello and Desdemona. So due to Iago’s racist attitude towards Othello, Brabantio and few others tries to separate Othello from Desdemona. This shows how discrimination can affect love ones and individuals due to discrimination.In contrast Black Like Me a non-fiction novel based on a true story of John Howard Griffin, who changed his skin colour to black to try and find out how it feel likes to be black. He was called names like ‘nigger’ and he felt like an outcast amongst the white people, his own people. He found it hard to get along with white people as he gets ‘hatred glares’ from them but gets loving, w arm greetings and invitations from black people. Black people were being pushed away into hiding, poverty which caused a lot of sufferings for the black society as a whole, all young and old because of the colour of their skin.This shows that discrimination affected the black society leading them to poverty, misery, homeless and sufferings. The text The Untold Story of Emmett Louis Till shows an identical horrific incident that scarred the Black Society at that time and even up to now in America. A young boy named Emmett Till was brutally murdered in Mississippi, America. Emmett was 14 years of age when he was taken from his uncle’s house by two white men due to the fact that he whistled at a white lady.Emmett loved to play around and had a sense of humour which led him to whistling at the white lady which caused his death by the hand of two racist white men. This reason for their action was very unacceptable and racist because if it had been a white man who whistled at the l ady, the white people nor anyone would do anything but since Emmett was black and not white, he paid the price of death. These white people had to prove a point that they were superior and they had to prove it by killing a 14 year old boy.Emmett’s mother had to keep the casket open to show the world the face of her son and what the white people did to him. The result of the brutal manners that was done was unimaginable and indescribable. Emmett’s face was unrecognized by his family and friends but especially by his own mother. His teeth were knocked out and his mother â€Å"took pride in them because they were the most beautiful thing I have ever seen. † There was a massive hole on his head and his mother â€Å"could see right through. † His skull was broken in the middle and his tongue was cut and hanging down.The world attended the funeral to have a look at Emmett and this angered the white people. They sent racist letters of threats calling names like â€Å"niggers†, â€Å"savages† and treat of house being bombed. This text shows how black and white were separated by racism and how discrimination took control destroying the black society physically and emotionally. How does the context (time, place, social condition and other people) enhance the occurrence of discrimination due to racism? My text consistently displays the social condition, times and places where/when white were superior of all races.A time we now look back and feel embarrassed that it ever happened, a time of suffering, of pain, of struggle and temptation but hope was always in front and kept them going. In Dawn Raids this event happened in the mid-1970s to early 1980s during the most embarrassing time of New Zealand, where most islanders were being woken up early in the cold mornings at dawn with dogs and flashlights trashing things that came their way, handcuffed and held in cells. These times made racism easier for polices because they had the au thorities to pick on anyone but they chose only to pick on brown faces for over stayers.It was during the time when New Zealand brought Pacific Islanders to New Zealand to work in factories and do hard works and by that it meant that Pacific Islanders had to obey Pakehas and do as they are told. They lived in fear and under pressure because their lives were being controlled. This shows that discrimination affects and destroys lives of the Islanders and it should have been prevented and stopped. In Freedom Writer is based on a time where whites were still superior to all races and black being the lowest of them all and a time in America where black people were blamed for almost every crime.This show a time where freedom was deprive of the non-white people due to racism. Othello is a text that was influenced by the occurrence of racism through words of hatred, jealousy and a time where people believed in strange things concerning the devil, more religious believers and strong Christia n faiths. Iago refers to Othello as the â€Å"devil† even though Othello’s Christian, as indicating that black were evil and that â€Å" the devil† often took the form of a black man, which as to make Othello seem as something miserable and should be treated like an animal.These racist words of Iago were used to persuade Brabantio that it is impossible for Desdemona to fall in love with Othello because of his race. This shows a time where Othello’s race was seen as something not desirable or wanted. Othello is similar to Black like me where in accordance with social segregation of time, finding a job for black people was difficult and hard. They couldn’t find a restroom or cafe allowed for black to enter and use. This shows a time in America where black people were neglected of their needs and social involvement because of their skin colour.According to The untold story of Emmett Till and it’s devastating incident, that occurred during the t ime of the white being superior to black and slavery still seen around, black people were seen lower than whites and other races. Black people would be treated like animals and white people would get away with it. it shows a time where black people at that time still had no protection from the law, a time where they weren’t yet allowed to vote or speak their minds. This made racism worse for black people because they had no say in anything, due to most of them being brought up in the culture of slavery.So, in these texts it shows how the context can enhance the occurrences of racism shown through discrimination and why discrimination should be stopped. Why do people discriminate (including those in the texts)? There is no single, simple answer to this question. To begin with, it seems to be a human trait to dislike and distrust anyone we perceive as being â€Å"different. † It also seems to be a human trait to judge groups of people by the actions and attitudes of a fe w and it also seems to be a human trait to think that what we believe, how we live, and what we are is the only â€Å"right† way to believe, live, and be.People are not born racist and they learn this behaviour from their family, friends, and other important people in their lives. This is a personality disorder, I believe, based on a person's lack of self-worth. During the years of Affirmative Action (employment preference given to blacks) in America, many non-blacks were passed over for promotions and jobs which they considered rightfully theirs and this caused a great deal of bitterness. This particular program has not been around for many years, but older workers probably recall it clearly and still hold a great deal of resentment, like wise shown on the text Black Like Me.Some people  discriminate due to one's skin colour being different from theirs, backgrounds and where they’re from. It shows that white people discriminate black people because they believe that they are superior and they can do anything and get away with it without punishments. In Dawn Raids it shows that polices discriminate because immigrants were getting bigger and better in New Zealand and plus they didn't need them anymore; they had no use for them any longer.That was a selfish and unloving way, of how discrimination worked. Iago in Othello was totally under the influence of jealousy and hatred towards Othello, which resulted in a very tragic event of deaths and broken hearts and trusts between the two lovers, Othello and Desdemona, together with the help of religious faith and beliefs. In The Untold Story of Emmett Till it shows that the â€Å"white society† discriminates basically because of skin colours and ethnicity together with the echoing background of slavery from years ago.Similar to Freedom Writer it shows that students discriminates because of things that happened in the past, stories told by their fathers, their brothers, sisters and mothers. They kill each other and fight against each other even to death, shooting each other down because of the fact that their backgrounds and ethnics are different, they believe in different things and their past experiences due to racism and racial-hatred. Hatred and fear of others being superior or overpowering them made discrimination stronger but less do they know that they all have a lot in common than they know of.So discrimination should be stopped because it is unfair, unloving, painful, sorrowful and straight inhuman-like and lets come together and try make a difference for our next generations. Conclusion: People discriminate for many reasons; fear, envy, desire for power or a need to disassociate them from others but especially because of racism. Racism is and will always remain a central issue which is heard, seen and recognized in most countries, in societies and amongst individuals which causes a lot of sufferings.These issues of discrimination scars every aspect of economic cul tural and political life by overt or covert racism acts, either in offensive loud bang or in a subtle manner. In many ways discrimination due to racism blur the line of accepted and unaccepted societal norms, that to destroy and subjugate others –either through perpetuation of physical violence or words– is a phenomenon as old as time. These actions wounds societies and people as individuals which healed but left scars that will never fade or forgotten.What is disconcerting are the facts, figures and the damages caused to an individual and society as a whole. Painful tortures done behind doors and are swept under the rugs without others knowing or recognizing the damages. Hundreds of years ago people have paid a price for being racially different, tortured, and subjugated or killed, despite the advancement in culture, science and technology. People have been categorized and stereotyped which made discrimination easier. The root of the problem lies in our physical or cu ltural differences which involves skin colour, anguage, religion or tribe, hence the solutions too comes from this problem of being different. We should learn to love the different cultures and when  we meet people and learn about them we are really all just the same. I have zero tolerance for racism because it has resolved nothing for as long as racism has been, and it's the likes of JFK, Bobby Kennedy and Martin Luther King, Jr, losing their lives for these very principles to make one realize that certain people are terrified that wars that should never have been, will be ended and there will be equality for all races of man.We should learn from these great men and strive to get along together rather than to fight with one another. I believe that by accepting and maybe celebrating differences is just one way of educating ourselves on these differences of cultures, and just maybe, a zero tolerance towards racism as an individual or society as a whole could pave the way for less o f it and try make this world a better place, discrimination-free and racism-free for our children, our children's children.A world where we can all come together as one with peace and love no matter what race, skin-color or country we're from, because I believe that  without discrimination and racism, the world would be a much better place for our species to multiply and replenish with equality for every man no matter what differences we have. Discrimination and racism should be stop and prevented forever. Don’t ignore or avoid the scars of discriminations.

My Beach Memories

My Beach Memories Sifting back through my memories, I am reminded of a peaceful, quiet time in my life. My mind drifts back to a happy place of relaxation and tranquility. I am able to remove myself from all the continued chaos of everyday life. Sitting on the sand, feeling the warmth of the sun, all of my troubles quickly melt away. I can feel the soft, wet sand as my skin melts into it, reminding me that I have no deadlines to meet or no place to rush off to now. The cool, crisp water feels exhilarating as it rushes over my body. As the ocean waves crash against me, I can still feel the sting of the fine ocean mist and the pungent taste of the salt as it sprinkles over my face. The fresh smell of the salty ocean water clears my sinuses as I synchronize my breathing with the ebb of the tide. Lying quietly in the sun, I can feel its warmth engulfing me like a large fuzzy blanket covering my skin. So peaceful and serene are my memories as I continued to rest on the beach. I can still hear the crash of the water against the rocks. The ocean birds' songs still echo in my head as they sang me to sleep on the soft, warm sand. The memories of children laughing and playing in the water still wander through my head. I also remember the sounds of seagulls chirping as they glide over my paradise. Having not a care in the world, could there be a more wonderful place? The sun sets softly behind the large palm trees as the wind gently blows salt and sand against my body as I sit and watch. The air turns cooler as the night begins. I can see millions of twinkling stars, as I get lost in their magic and mystery. It seems as if time is frozen no worries or stress to cloud my mind. I can be free to dream and ponder over all of my desires. Sitting quietly on the beach, I can be free. These fond memories are my pathway to escape from reality. Even if the moment is brief, it is long enough to rekindle my desire for life. Just reminiscing over my time at the beach has rejuvenated my wayward mind and wilting body. I can go back to my happy place any time I desire. I have such fond memories of the beach. I will never forget how peaceful, relaxing, and beautiful my favorite place has been to me.

Compare the heights of girls and boys in year 8 and the sixth form Essays

Compare the heights of girls and boys in year 8 and the sixth form Essays Compare the heights of girls and boys in year 8 and the sixth form Essay Compare the heights of girls and boys in year 8 and the sixth form Essay The purpose of this exercise is to compare the heights of girls and boys in year 8 and the sixth form, in an attempt to show the following. That in year 8, girls and boys will have more similarities in height, but girls are more likely to be taller than the boys. In sixth form there will be greater differences between the heights of boys and girls and the boys are more likely to be taller. That there will be a much greater difference in the heights of boys between year 8 and sixth form than between the girls. I will attempt to show this by measuring the heights of boys and girls in year eight and the sixth form. In each case a sample size of fifty will be used in order to produce statistically valid results according to the central limit theorem. This will be done, by obtaining a sample that accurately represents each group. Firstly a list of boys and a list of girls in year eight and the sixth form will be formulated giving each student a number. Then a random number generator will be used to select fifty boys and fifty girls from each year group. I will measure the selected groups independently using the measuring device illustrated below. This device includes two, one meter rulers fixed against the wall, the mark for 0 cm is in line with the floor, and the second ruler is fixed alongside the first so that its 0 cm mark is in line with the firsts 100cm mark. Then two, 30cm rulers with millimetre measurements are fixed, one either side of the second meter ruler, at 140-170cm and 170-200cm, again the 0cm marks for each of these rulers were fixed in line with 140cm and 170cm respectively. This will help to ensure accurate measurements. Students will be asked to remove their shoes, stand up straight, flat on their feet, with their backs against the wall. The setsquare will be held against the wall and the individuals head. The height will be read and recorded. Each height will be measured to millimetres to ensure obtaining a reading that is as accurate as possible. The results were as follows.

This will be done by adding together all of the heights in one group and dividing it by 50 (the sample size). This will be repeated for each of the remaining groups. This calculation is represented by the following formula. Next calculate the standard deviation, which is found by taking one group e.g. Year 8 boys and subtracting the mean from one of the scores. The result of this is squared. This is repeated for every score and the mean of the squared differences is worked out. This is the variance. To find the standard deviation you must square root the variance. This calculation is represented by the following formula. USEFUL BACKGROUND INFO THE CENTRAL LIMIT THEOREM If the sample size is large enough then the distribution of the sample means is approximately normal, irrespective of the distribution of the parent population. The mean of the distribution of the sample means is approximately equal to the parent population. The variance of the distribution of sample means is approximately the variance of the parent population divided by the sample size. These approximations get closer as the sample size gets bigger. These results are known as the Central Limit Theorem. Symbolically if, X ~ (unknown)(?, ?à ¯Ã‚ ¿Ã‚ ½) then ? n ~ (?, ?à ¯Ã‚ ¿Ã‚ ½/n) Provided n is sufficiently large. (n ? 30 is usually a good size). Standard error The standard deviation of the distribution of sample means is called the standard error. 1 s.e = ?à ¯Ã‚ ¿Ã‚ ½/n (variance of the distribution of x = ?à ¯Ã‚ ¿Ã‚ ½/n) In previous calculations I have only worked out the mean x and variance sà ¯Ã‚ ¿Ã‚ ½ of my sample. I cannot calculate confidence intervals for population mean à ¯Ã‚ ¿Ã‚ ½ because I do not know ?à ¯Ã‚ ¿Ã‚ ½. Unfortunately sà ¯Ã‚ ¿Ã‚ ½ is not an unbiased estimator of ?à ¯Ã‚ ¿Ã‚ ½ (i.e. the mean of the distribution of sà ¯Ã‚ ¿Ã‚ ½ is not equal to ?à ¯Ã‚ ¿Ã‚ ½). However Is an unbiased estimator of population variance, and I can use this as an estimate of ?à ¯Ã‚ ¿Ã‚ ½ when calculating standard error in order to produce confidence intervals for à ¯Ã‚ ¿Ã‚ ½. So in order to calculate the standard errors for each of my groups I must first calculate an estimate for ?à ¯Ã‚ ¿Ã‚ ½, using the above formulae. CALCULATIONS FOR THE ESTIMATES ?à ¯Ã‚ ¿Ã‚ ½ AND STANDARD ERRORS I have previously calculated the mean (x) and standard deviation (sà ¯Ã‚ ¿Ã‚ ½) for each of my groups. I will now calculate an estimate for ?à ¯Ã‚ ¿Ã‚ ½ in order to calculate the standard errors and formulate confidence intervals for each of my groups. To estimate ?à ¯Ã‚ ¿Ã‚ ½ I will use the previously stated formula. And then using these estimates for ?à ¯Ã‚ ¿Ã‚ ½ I will calculate the standard errors using the formula. CONFIDENCE INTERVALS If we have one sample mean x then P(à ¯Ã‚ ¿Ã‚ ½ 1s.e x à ¯Ã‚ ¿Ã‚ ½ + 1s.e), but this can be rearranged à ¯Ã‚ ¿Ã‚ ½ 1s.e x x à ¯Ã‚ ¿Ã‚ ½ + 1s.e == à ¯Ã‚ ¿Ã‚ ½ x 1s.e à ¯Ã‚ ¿Ã‚ ½ x + 1s.e So P(x 1s.e à ¯Ã‚ ¿Ã‚ ½ x + 1s.e) = 0.68 I.e. There is a 68% chance that à ¯Ã‚ ¿Ã‚ ½ lies within ? 1s.e of my x. This is known as a confidence interval for the population mean. In this investigation I am going to calculate confidence intervals for each of the individual groups. I am going to use 95% confidence intervals so I will have to calculate a z score for 95%. The z score is the number of standard deviations units away from the mean value. Using numerical methods, accurate tables have been constructed for the area under the normal curve. The table gives the area to the left of (or below) any given z- value. The area under the Standard normal curve that is to the left of z is denoted by ?(z).This is represented by the following diagram. I will obtain a z score for 95% as follows. The area to the left of the z = ?(z) = 0.95 + 0.25 = 0.975 Using the normal distribution table z = 1.96.This will be used in calculating the confidence intervals for each group. CALCULATIONS OF CONFIDENCE INTERVALS. Using my previous calculations for the z score for 95%, the mean of each sample and the standard errors. I will now formulate confidence intervals for each of my groups. YEAR EIGHT BOYS x = 154.1 s.e = 1.19 z score 95% = 1.96 (this will be used for all the groups) P(à ¯Ã‚ ¿Ã‚ ½ 1.96s.e x à ¯Ã‚ ¿Ã‚ ½ + 1.96s.e) = 0.95 P(x 1.96s.e à ¯Ã‚ ¿Ã‚ ½ x + 1.96s.e) = 0.95 P(154.1 1.96 x 1.19 à ¯Ã‚ ¿Ã‚ ½ 154.1 + 1.96 x 1.19) = 0.95 95% C.I for à ¯Ã‚ ¿Ã‚ ½ is (151.8 156.3) . YEAR EIGHT GIRLS x = 158.3 s.e = 0.94 P(à ¯Ã‚ ¿Ã‚ ½ 1.96s.e x à ¯Ã‚ ¿Ã‚ ½ + 1.96s.e) = 0.95 P(x 1.96s.e à ¯Ã‚ ¿Ã‚ ½ x + 1.96s.e) = 0.95 P(153.8 1.96 x 0.94 à ¯Ã‚ ¿Ã‚ ½ 153.8 + 1.96 x 0.94) = 0.95 95% C.I for à ¯Ã‚ ¿Ã‚ ½ is (156.5 160.1) SIXTH FORM BOYS x = 176.7 s.e = 1.08 P(à ¯Ã‚ ¿Ã‚ ½ 1.96s.e x à ¯Ã‚ ¿Ã‚ ½ + 1.96s.e) = 0.95 P(x 1.96s.e à ¯Ã‚ ¿Ã‚ ½ x + 1.96s.e) = 0.95 P(176.7 1.96 x 1.08 à ¯Ã‚ ¿Ã‚ ½ 176.7 + 1.96 x 1.08) = 0.95 95% C.I for à ¯Ã‚ ¿Ã‚ ½ is (174.6 178.8) SIXTH FORM GIRLS x = 161.4 s.e = 0.99 P(à ¯Ã‚ ¿Ã‚ ½ 1.96s.e x à ¯Ã‚ ¿Ã‚ ½ + 1.96s.e) = 0.95 P(x 1.96s.e à ¯Ã‚ ¿Ã‚ ½ x + 1.96s.e) = 0.95 P(161.4 1.96 x 0.99 à ¯Ã‚ ¿Ã‚ ½ 161.4 + 1.96 x 0.99) = 0.95 95% C.I for à ¯Ã‚ ¿Ã‚ ½ is (159.5 163.3) These results are represented by the following graphs. ANALYSIS OF RESULTS The first set of box plots shows the 95% confidence intervals for à ¯Ã‚ ¿Ã‚ ½ for the year eight boys and the girls. They show that the majority of girls and boys in year eight are very similar in height, but girls are more likely to be taller. The second set of box plots shows the 95% confidence intervals for à ¯Ã‚ ¿Ã‚ ½ for the sixth form boys and girls. They show that there is a great difference in the heights of the girls and boys, and it is the majority of boys that are taller. The third set of box plots shows the 95% confidence intervals for à ¯Ã‚ ¿Ã‚ ½ for the boys in year eight and sixth form. They show that the majority of boys are a lot taller in the sixth form. The fourth set of box plots shows the 95% confidence intervals for à ¯Ã‚ ¿Ã‚ ½ for the girls in year 8 and the sixth form the majority of girls in both years are much more similar in height than the boys. The majority of girls in sixth form are more likely to be taller. CONCLUSION AND ANALYSIS My results have shown my hypothesis to be correct. They show that: In year 8 girls and boys have more similarities in height, but girls are more likely to be taller than the boys. In sixth form there are greater differences between the heights of boys and girls and the boys are more likely to be taller. There is a much greater difference in the heights of boys between year 8 and sixth form than between the girls. I believe these results are fairly reliable, as I would say that I obtained my samples of girls and boys in year eight and the sixth form as accurately as I possibly could have given the facilities and amount of time that was available. I also think that using these samples I fairly accurately estimated the confidence intervals for the population mean of each group. I dont think there is much I could have done to improve the method of obtaining the sample or the method I used to measure the heights. The accuracy of my results would improve by using a larger sample size e.g. 100 girls and boys from each year group, according to the central limit theorem. However, this was not possible due to the amount of people available to measure and the amount of time allocated. I could have improved the sample further by taking groups of students from different schools in different areas, this may have given a more accurate representation of the population, as the ranges of heights in different areas for each group may be more varied. However this would have been very difficult to do and would have taken too long, also I dont think it would have shown any great difference in my findings, as the heights of boys and girls in each group throughout the region are most likely to be fairly similar to those I measured. If I had had more time it would have been interesting to find out where exactly the changes in the heights of boys and girls actually occurs. This could have been done by taking a sa mple of fifty girls and fifty boys from each of the years in between year eight and the sixth form, and again calculate confidence intervals to see when the boys go from being the same height or shorter than the girls to being much taller than them.
