Oliver Twist Essay Example for Free

Oliver Twist Essay In Oliver Twist Bill Sykes brings terror to the novel, which adds to the suspense and makes you want to read on. Bill Sykes is brutal which you soon realise when he delights in beating his dog or girlfriend, Nancy. Many novels of this time were full of such characters and Dickens, a playwright and an actor as well as a novelist, knew then well. The orphan Oliver Twist escapes from the workhouse by running away to London. Oliver is introduced to Fagin who trains him to be a thief and he is then taken on a burglary with Sykes, Oliver recovers from being shot in the burglary and Nancy nurses Sykes back to full health. Sykes kills Nancy, which has a terrible effect on him, and he later kills himself. Bill Sykes brings the real terror to the novel but he is also extremely unpredictable. Rarely he can seem quite reasonable and occasionally shows kindness to his dog and girlfriends, but generally he keeps everyone in fear of what he is going to do next. We see evidence of this when Fagin says, You wont be too violent Bill? This statement shows that they have no trust in him. Bill Sykes also has a problem with alcohol, he drinks far too much, and this probably accounts for some of his unpredictable behaviour. We see evidence of his drinking problem when he says, to prevent my standing treat for a pint of so. This shows that he thinks that he thinks drinking is a treat and does not himself think that he has a drinking problem. Bill Sykes us the archetypal Victorian villain. To be a real villain Sykes must show no compassion for anyone and we see that on many occasions. When Nancy has nursed him back to health, staying up for nights looking after him, he turns on her the moment he wakes up. This shows he is very ungrateful for any sympathy given to him. Illness had not improved Mr Sykes temper, for as the girl raised him up and led him to a chair, he struck her . He is also quite ready to send Nancy out to work and possibly profit from what she does. From all of this we can gather further evidence that he is ungrateful for any help he received. Sykes treats his dog very badly, it receives regular kicks and is threatened constantly. At one time when he was going to escape he contemplates killing, The dog, though. If any descriptions of him were out, it would not be forgotten that the dog was missing. Sykes is a typical bully who shows no remorse for what he does to others. We see evidence of this when he takes Oliver on the burglary with him and does not care whether Oliver gets injured. Sykes has no respect for Fagin and you can tell this by the way he speaks to him. You can see Fagin is afraid of him but Fagin does like to have the last word. If Sykes does not get his own way he will turn to violence as we see with the arguments over Oliver, looking sternly at him, and ostentatiously passing a pistol into a more convenient pocket. Thats lucky for one of us. This shows again Sykes is unpredictable and a bully and brings more tension. When Bill Sykes sees Fagin, Fagin changes the tone of his voice at once. Fagin is obviously afraid of the physical strength of Sykes but Sykes is still wary of Fagin.

Global Warming Is Eroding Glacial Ice :: Analysis, Andrew C. Revkin

People are responsible for higher carbon dioxide atmosphere emissions, while the Earth is now into the Little Ice Age, or just behind it. These factors together cause many years discussions of the main sources of climate changes and the temperature increasing as a result of human been or natural changes and its consequences; even if its lead to the global warming, or to the Earth’s cooling. In their articles, â€Å"Global Warming Is Eroding Glacial Ice† by Andrew C. Revkin and â€Å"Global Warming Is Not a Threat to Polar Ice† by Philip Stott, both authors discuss these two theories (Revkin 340; Stott 344). Revkin is right that global warming is taking place. Significant increase of carbon dioxide in the atmosphere is due to human activities combined with natural factors such as volcanic emissions and solar radiation – all together they lead to climate changes and temperatures rising. At the same time, other factors such as deforestation contribute to envi ronmental changes for some glaciers not less than air pollution. However, during global warming not all regions of the planet are affected in the same way, local warming and cooling are both possible during these changes. First, during the last few decades the Earth is experiencing greater rate of rising temperatures due to greenhouse gases that are being produced by human activities rather than because of environmental reasons, such as solar or volcanic activities. In 2006 the President of the National Academy of Sciences stated: â€Å"There is no doubt that the Earth is warming,† also he added that people are at least partly responsible for these changes in addition to regular factors (Cicerone, par.4). Natural factors have produced climate fluctuations on Earth for several million years. People have effected an atmosphere of the Earth just for nearly one hundred years, since Industrial Revolution has begun (Revkin 340). Of course, it is unfair to say that global warming is caused entirely by humans. For example, people can not have an impact on the position of Earth in relation to the sun, or on the galactic density, or such nature events as air emissions of volcanic gases. As a result of th ese environmental factors, Earth usually had higher rates of temperature fluctuations during the previous million years than it has in later centuries. On the other hand, people are responsible for the highest concentration of greenhouse gases during the last 650,000 years in the atmosphere due to industrial manufacturing, driven by the increase in consumer consumption (Lindsey, par.

AIDS Article

The article is written by a gay man, who lost his first partner to AIDS and dedicated himself to spreading information about HIV prevention and campaigning for governmental attention to the problem in order to save ‘other gay and bisexual men from losing the ones they love’ (Williams, 2006, para. 6).Clark Williams also served as the interim executive director of the Billy DeFrank LGBT Community Center at the moment of the article’s release and as a manager of county’s HIV prevention, counseling, and testing initiatves in 2001-2003.The article reports the LGBT community of Santa Clara County joining other concerned citizens at a meeting where the county’s Board of Supervisors Chair promised to attract additional financial resources to strengthen public health system in the face of accelerating rate of HIV transmission.The focus of the effort should be prevention and early diagnosis. The article recalls the start of HIV/AIDS epidemic that was first reg arded as a rare form of cancer endangering gay and bisexual male New Yorkers. In 2006, the number of Americans who died from AIDS reached 550,000 and continued to grow. Approximately 40,000 citizens are getting infected with HIV every year.Santa Clara County, for its part, has lost 2,000 residents to the disease. More than 2,500 were living with HIV/AIDS; this number might have been considerably higher because one in three citizens having HIV remains undiagnosed. 80 percent of new infections with the virus in Santa Clara County were among gay and bisexual males.Santa Clara County is reported as being ‘near the heart of our nation's HIV/AIDS epidemic’ (Williams, 2006, para. 5). Apart from focusing on the human tragedy of living with HIV diagnosis or loosing a friend, a family member, a colleague, or a neighbor to the disease, the article discusses the problem of HIV/AIDS through the prism of financial burden on the county’s social security system.Lifetime cost of HIV treatment is estimated to be as high as $155,000 per patient. These costs are much higher if the disease is not diagnosed at early stages, which is often the case in Santa Clara County, where patients learn about their HIV status in an emergency room.However, the author notes several positive developments in the field of public health, such as risk reduction counseling to people living with HIV/AIDS and public HIV test counseling locations. Santa Clara County is compared with San Francisco, where HIV test counseling facilities are abundant. In Santa Clara County, there is only one public testing facility, despite the fact that the number of LGBT is over 100,000 in the area.The Billy DeFrank LGBT Community Center is deemed as the most appropriate place to establish another full-time test counseling facility, since it is known for its excellence in providing HIV prevention to at-risk population.One additional testing facility will not solve the problem in the county. It is not onl y LGBT population that is especially affected by the spread of HIV/AIDS. Other vulnerable groups include ethnic minorities, homeless and runaway youth, and drug addicts. Therefore, five part-time testing centers should be opened across Santa Clara County.One of the main strengths of the article is the fact that it is written from an insider’s perspective. Rapport between the author and readers is immediately established when Clark Williams shares his personal tragedy of loosing his loved once to AIDS.However, emotional pathos is not the main component of the writer’s credibility: Williams is a leader of Santa Clara County’s LGBT community, knowledgeable of the actual Status Quo with regard to HIV/AIDS prevention and counseling.

Quetiapine, also known for the trade name Seroquel and chemical name 2-[2-(4-dibenzo [b,f] [1,4]thiazepin-11-yl-1-piperazinyl)ethoxy]-ethanol fumarate, is an atypical antipsychotic, currently prescribed as a form of treatment for schizophrenia, bipolar disorder and depression. Quetiapine originally became available for treatment in 1997 in the United States and is still presently used as a form of first-line treatment (Riedel, Muller, Strassnig, Spellman, Severus, Moller, 2007). For patients of bipolar disorder, Quetiapine has established efficacy in the treatment of acute mania and depression. Specifically, Quetiapine has been utilized as both a monotherapy and an adjunctive therapy for adults and adolescents with bipolar disorder (Dando Keating, 2005). While the pathophysiology of bipolar disorder is quite ambiguous, the disorder is known for strong heritability, which has led to large bodies of research surrounding the genetic profile of the disorder. Specifically, the monoamine hypothesis and the hypothesis of low serotonergic function are cited as potential causes of depressive and manic episodes (Newberg, Catapano, Zarate, Manji, 2008). The hypothesis states that abnormalities of the noradrenergic, dopaminergic, and serotonergic systems are present in bipolar disorder. In the pharmacological treatment of bipolar disorder, the dopamine D2 receptor is commonly blocked, in order to regulate dopaminergic systems. (Newberg et al., 2008). There is addition al evidence of low levels of plasma in the GABAergic system and elevated levels in the Glutamatergic system. The pathophysiology of bipolar disorder is also evidently connected to intracellular cascades, and specifically, reductions of volume in the dorsolateral prefrontal cortex and low glial cell density (Newberg et al., 2008). Don’t waste time! Our writers will create an original "The Utilization of Quetiapine in The Treatment of Bipolar Disorder" essay for you Create order Quetiapine, in the treatment of bipolar disorder, is an antagonist of serotonin, dopamine, histamine, and norepinephrine. While the precise mechanism of action of quetiapine is unknown, the drug inhibits 5HT1A, 5HT2A, D1, D2, alpha 1, and alpha 2 receptors (Dando Keating, 2005). Quetiapine is taken orally, and is mainly metabolized in the liver. The drug reaches steady-state plasma levels within two days of dosage, and the half-life is close to 6 hours. The drug is usually administered twice daily with an effective dosage of 400 to 800 milligrams per day (Dando Keating, 2005). Quetiapine is well tolerated, however, patients may experience side effects such as weight gain, dry mouth, dizziness, sedation, constipation, vomiting, or headache. Quetiapine is highly efficacious in the reduction of manic and depressive symptoms in patients of Bipolar Disorder (Dando Keating, 2005).
