Immune System and New York Essay HIV And Its Effects Elizabeth Grundy Psychology 102 Dr Peggy Peach October 10, 2001 HIV And Its Effects 2 HIV AND Its Effects The effects HIV has on a person, symptoms, risks, history and prevention will be explained. HIV is on a rise among sexually active people. According to Packer (1998), HIV, the virus that causes acquired immune deficiency syndrome (AIDS), is a member of a family of viruses. The first member HTLV-I and related to STLV-I researchers believe they both have a common ancestor in Africa. (P.13). This will be explained in the following questions: 1. What are the symptoms of HIV? 2. What are the risks to getting HIV? 3. What is the history of HIV? 4. What is the treatment for HIV? This research paper on HIV will be focused on these four questions. 1. What are the symptoms of HIV? According to Nash (1997), when a person infected with HIV has symptoms such as fever, night sweats, weight loss, fatigue, and lymphadenopathy (persistent, unexplained swelling of the lymph nodes), but no opportunistic infections (illnesses that healthy immune systems fight off) or Kaposis sarcoma, he is said to have AIDS-related complex (ARC). The acronym ARC is not used as frequently as it was in the early years of the epidemic. AIDS is now thought of in term of a HIV continuum. It begins with HIV-positive diagnosis in a person who is not experiencing any symptoms. It continues to a symptomatic stage in which the person has opportunistic infections, HIV and Its Effects 3 andKaposis sarcoma, or any of the conditions previously used to define Arc, and the HIV-positive continuum ends with full-blown AIDS diagnosis (p.22). 2. What are the risks to getting HIV? According to Nash (1997) No one is safe if his or her behavior is not safe. You do not get HIV because of a group you belong to; you get HIV from exposure to the virus. HIV can be contracted through unprotected sex with an infected person, by sharing needles when using drugs, or by tattooing or piercing body parts with a needle that has been used on an infected person. (P 24). According to Draimin (1995) the four common most ways HIV can get into the  body, Dirty needles used to inject drugs, unprotected sexual intercourse, mother to fetus or new-born baby, and blood transfusion. (P.11) HIV is transferable through any kind of sexual contact: heterosexual, homosexual, or bisexual. The means of transferring the virus is unprotected sex. The safe guards against contracting HIV are to have sex only when you are ready, to know your partner, and to protect yourself from possible infection every time you have sex by using a condom. The HIV virus, like some other viruses cannot live outside the body. It is killed by air. HIV requires a warm, wet place to live and be carried only in blood, sexual fluids, and possibly saliva. Sexual transmission of HIV means that the virus goes from fluid to fluid (semen, vaginal, and blood). The virus has to pass from fluid to fluids to stay alive. (Pp25-26) 3. What is the History of HIV? HIV and Its Effects 4 Hyde and Forsyth (1 996) In 1981, when the first mysterious cases of an unusual type of pneumonia began to appear, scientists have accumulated a large body of knowledge about HIV. The first alarm sounded before aids even had a name, when doctors realized that some formerly rare diseases were becoming common among homosexual men in the United States. The first well-documented cases of what was later called AIDS were found in San Francisco and New York in 1981. A young gay man in San Francisco was found to be suffering from severe fungal infection to which he had little immune reaction. In fact, his immune system did not respond to any disease. Then he developed Pneumocystis carinii pneumonia (PCP), a type of pneumonia that is caused by a parasite. This disease is usually found only in severely malnourished individuals or people whos immune have been impaired by drugs such as those used in treatment of cancer. (p.56) According to Nash (1997) In 1982, three non-drug -injecting heterosexual men with hemophilia A developed AIDS and were reported to CDC. Hemophilia A, a blood -clotting defect, requires transfusions of blood-clotting factors derived from whole blood. (p.29) In June 1981 the first report of what AIDS, published by CDC described the new disease as a collection of characteristics symptoms among various population groups. It was a narrow definition, involving the presence of one or more opportunistic infections or cancers, and signs that general failure of immune system had occurred. (Nash, 1997) 4 What is the treatment for HIV HIV and Its Effects 5 According to Nash (1997) AIDS symptoms typically takes years to develop after the initial infection.  Scientists are researching what they call immunotherapy. Vaccines to prevent or stop a disease from taking hold; immunotherapy intervenes before symptoms arise and rids the body of infection. Management drugs have come out such as; Azidothymidine (AZT), this is the first of its kind. It interferes with HIV reproduction inside the cell; it slows the process of AIDS down. An HIV- positive person who takes AZT before AIDS symptoms appear lives longer than those who did not. Dideoxycytidine (ddC) and dideoxyinosine (ddI) offer another approach to combine therapy. Death rates are lowered when ddC and ddI were taken in combination of ddC and AZT or ddI and AZT then those patients who took AZT alone. Ampligen-, which did not help the patients when administered, alone-used in combination with AZT increase the effectiveness of both drugs. Epivir (3TC) became the first new initial therapy since AZT. The combination therapy of 3TC and AZT lowered the amount of HIV in patients and boosted their immune system. Invirase (protease inhibitor) is designed to cripple an enzyme vital in late stages of HIV reproduction, which is used in combination of other anti-HIV drugs. They reduce the levels of the virus in some people and increase the number of immune cells in some patients previously depleted by the virus. In 1996 Ritonavir, another protease inhibitor was also approved. HIV and its effects on those we know and love are about learning to manage the illness. People need to practice safe sex and to and to pay attention to safe behavior. HIV and treatment have come along way. Medical science has along time to go before a cure.

Once Upon A Time By Gabriel Okara English Literature Essay

Once Upon A Time By Gabriel Okara English Literature Essay The poet of the poem Once upon a time is Gabriel Okara who is a Nigerian. He was born on 24th or 21st of April in the year 1921.In that year Nigeria got independence from Britain so at that time they were still influenced by the British culture. The background of the poem is that he is remembering the way people used to behave and interact with each other and he is comparing it with how people interact with others now. How the people used to do things with their hearts and with pleasure and happiness. It describes what happens when a traditional African culture and civilisation meets with the western culture. My personal opinion of the purpose of this poem is to outline the behaviour and personality people have at the moment and try and bring them back to the personality that people used to have, when they used to do things with emotion and with their heart The poem is a conversation between a father and his son where the son does things with emotion and the father wants to forget his fake personality and re-learn and create real personalities from his son. And he is asking the son to show him how to express true love and show real personality to others. It the first stanza the author mentions that people used to laugh with their heart they used to laugh with their emotions, when they would laugh they would do it wholeheartedly and with warmth and they used to laugh with their eyes and show pleasure with them. And know they do it with only their teeth not with their heart, meaning they do not really want to laugh but do it just to get closer to you and with their darky gloomy cold eyes they watch you and wait for you from the corner of their eyes waiting for you to leave search behind my shadow. In my opinion the words they refer to the white people who had invaded their country and influenced them with their culture. In this stanza the words ice-block-cold eyes is used these words emphasize the coldness and the inner hatred they have for you like they can freeze water with their gaze. These also make the poem feel a bit dark and cold and a slight bit sinister In the second stanza he further talks about the personalities of the people of the past he says they used to shake with their hearts here he is trying to say that when you would meet each other you will shake their hands with pleasure and with warmth and do it willingly. While their left hands search my empty pockets from this we can see that they are trying to use him to get to his money or receive something from him. This also shows that the peoples personalities are not real and true In the third stanza he is talking about when people ask you to come again and say feel at home you go there once, twice and the third time they will not let you in thinking that you are a pest and that they do not wanted to see you anymore. The words feel at home is used for when you want a guest to feel welcomed and that they belong in that household. Here he mentions that I find the doors shut on me this shows that they do not even open the door to tell him that he is not wanted and the moment but instead leaves the door closed keeping him standing outside. This also shows that when people speak they lie not telling the truth but just saying something nice to grasp their heart. In the fourth stanza he talks about how he has learned to put on faces like how outfits and masks are put on at different times, and with different people you act differently, for example in the office you act in one way to a person but when you meet them on the street you act another way to them, and how all the faces that people have on different occasions. He says I have learned too which is suggesting that he has also changed with the change of the people around him. he also mentions with all their conforming smiles like a fixed portrait suggesting that they all have the same smile all the time not showing any true emotion. In the fifth stanza he says that he has also been influenced by the people around him and he has learned to keep his true personality a secret and show the world a fake personality, to laugh with only me teeth this part is connected with the part in the first stanza they only laugh with their teeth from this you can see a comparison of what people do and what he does now. This also shows that he has changed to blend in with the environment. Here in the part where he says I have also learned to say `Goodbye when I mean `Good-riddance that is pointing out to the fact that they will, without thinking and without meaning it they will say Goodbye. He mentions forward that Glad to meet you meaning that he is happy to see you and is happy with your presence without being glad meaning that the did not wanted to talk to you and they disliked your presence and if they could they would of avoided you and its been nice talking to you, after being bored saying that they say things that they do no t mean In the fifth stanza he concludes it all saying that he does not like what he has become and he wants to be like he used to be when he was like a child so small and innocent. He points out that he really wants to learn how to laugh with emotions like you really mean it and he compares his laugh like that of a snakes fangs that shows only the teeth snakes are those menacing creatures that are full of venom and can never be trusted and to compare his laugh with a snake gives the image that the man really does not like his fake personality. This stanza sums it well by giving the image to the reader that he is not happy and satisfied with himself The last stanza is the farther asking and pleading to his son to show him how to laugh and smile like he did when he was a child. The last line sums up the entire poem really well making sure that all strings are tied The structure of the poem is really good and consistent most of the stanzas have 6 lines in them. It is a very nice poem with a nice smooth flow

Plagiarism and the Internet :: Cheating Education Essays

Plagiarism and the Internet The Internet’s popularity has continued to grow since it first emerged, shocking the world with its never before seen technological capacities. It allowed for the communication of ideas and provided people with a wealth of information only a click away. More widely used now then ever before, the Internet supplies users with easy access to various kinds of information. With the unlimited availability of information on the web today, plagiarism has become a growing problem. The abundance of information available makes it easier and increases the temptation to steal other’s ideas. Plagiarism, which is taking credit for someone else’s ideas, is sometimes committed intentionally and other times accidentally. Often, copyrights are violated. In order to prevent this crime form being committed it is necessary that society is educated about copyright law and understands how to properly cite source material. If people understand what plagiarism is and the consequen ces they will face if detected, perhaps it is less likely that they will plagiarize. Today, 49% of people use the Internet as a reference source (â€Å"How† 1). It contains a plethora of information, and documents found on the web can be of great use when doing research. However, if ideas, concepts, or words are taken from another author’s work, they must be properly cited. If they are not properly cited this is plagiarism, which is considered to be unethical act by society; it also violates copyright law, and thus is punishable by law. Often people do not realize that even if they are only paraphrasing or summarizing someone else’s work, idea, or concept and not directly quoting it they are still plagiarizing. Borrowing another person’s idea is permissible if credit is given to whom it is due. However, stealing someone else’s work or idea and acting as if it were your own is not. Thus, it is pertinent that proper citation is always used. If one fails to use proper citation, one is guilty of plagiarism, and may face legal c harges for copyright violations. Plagiarism is not always committed intentionally, but the people who purposely attempt to deceive others by stealing someone else’s ideas should take into account the seriousness of their actions and the consequences they may face if caught. For those people who are guilty of plagiarism, but did so unintentionally and were simply unaware of what they were doing should also take into consideration their actions to try to prevent this act from occurring again in the future.

Internet Penetration :: Computer Science

Internet Penetration Identify the different levels of household penetration by the World Wide Web in each of the following continents – Asia , Africa , North America , South America and Australia . Explore the reasons for this variation. The countries with the highest internet penetration are predominately those Western economies with strong economies and high levels of affluence. Out of the top 10 countries, European countries feature 6 times, with Sweden having the highest penetration at 73.6% of the population have the internet. Other high ranking countries include Hong Kong (70.7%), The United States of America (USA) (68.5%), Australia (67.2%), Canada (63.8%), Korea (63.3%), Japan (60.9%), Taiwan (60.5%), Singapore (60.2%) and New Zealand (56.8%). The United Kingdom compares well at 60%. (Appendix 2 Internet world stats, 2005) World wide, these 25 countries dominate over 64% of their total population; the internet penetration in the rest of the world is just 7.8% of the remaining population. However, percentages can be misleading; whilst they give a good indication of levels of literacy, affluence and behaviour, the percentage of penetration would not give an indication of size of possible market; the USA has the largest market at 202,888,307; the next largest being Japan at 78,050,000 and then the UK and German markets at 35,807,929 and 47,127,725 respectively. Whilst we have seen then that internet penetration is very strong in these affluent societies, there are some interesting developments in the emerging economies. Those countries in Asia that have traditionally had under developed economies, such as China and India , have very different levels of internet penetration; despite both countries attempting to develop their economic wealth. China , with a population of 1,306,313,812 has 94 million internet users (Appendix 1); this however translates to only 7.2% of the population. The Chinese middle class is only 4% of the population i.e. those who have household incomes of more than $20,000 but that translates into a market or 50 million people (Khanna, T) – a huge market for prospective investors in the country. This compares very favourably with internet penetration in India – where the population is very similar to China 's - 1,080,264,388.00 but there are only 18, 481,000 internet users, a penetration of 1.71% of the population. This may be due to Government intervention in China ; in a recent report ‘it has been found that China has nurtured and directed the economy ( Khanna, T 2005). In addition there is a difference in the GDP per capita – in China , the GDP per capita is $5,600, whereas in India it is only $3,100. However, in both countries there is a huge gap between the wealthiest and poorest people, both in

Islamic Leadership

Leadership An Islamic Perspective In the introductory chapter the book establishes what you should know by the time you finish the book. These points include: understand the nature and process of leadership from an Islamic perspective, describe the characteristics of effective leaders in general, and of Islamic leaders in particular, analyze your styles as a leader and follower, learn how you can mobilize, organize, and develop your followers Islamically, learn how you, as a leader, can build commitment by acting as a coach mentor, learn how to delegate effectively, and finally understand the steps that will enable you to become a more effective leader. The book defines leadership as the ability to persuade others to seek defined objectives enthusiastically. Within an organization a good leader is needed but so is good management. There are different positions of power when in an organization. The first one is legitimate power, which refers directly to someone’s position in an organization. Reward power is the second type of power, this power refers to having the authority to hand out promotions or pay raises. The third type of power is called coercive power, which uses force to get employees to work. The final type of power is information power, this type of power deals with having and giving information to others so that they can do their work. According to the text there are certain characteristics of an effective leader. The book ranks them from 1 to 8. These characteristics include: honesty, competent, forward-looking, inspiring, intelligent, fair minded, straightforward, and imaginative. These characteristics were determined by a study done by two leadership researchers named Kouzes and Posner. They surveyed 2,615 of the most successful leaders in the United States in order to figure out and rank the characteristics. The book also discusses how leaders must mobilize, developed, and organize their followers. The reason mobilization needs to be done is due to the fact that leaders cannot and should not be expected to accomplish everything on their own. The people are the target of the message and are also the ones that will be spreading the word. Mobilizing followers includes being able to reach out to everybody. The message of Islam is one that is not elitist so in essence the ides that only a few people are capable of energizing a group is not correct. It also states that the reticent person may become the best person. This statement basically means not the prejudge people and to always give them a chance because they just may prove what you believe wrong. The third statement about mobilizing says to accept the verbal commitment of others to Islam at face value. This means to always accept a pledge someone makes. Another point the book makes is to welcome even sinners and try it improve them. In order to develop followers a leader must be able to adjust their leadership style due to the fact that the followers have different types of styles. There are four different types of leadership styles that a leader can turn to. These leadership styles include: directive, coaching, supportive, and delegating. The style the leader should pick depends on the maturity of the people being led. With immature members the leader may want to use a directive style. This is because it involves clear and explicit guidelines. A coaching style may then be implemented as the members begin to learn their task. This style is characterized by two-way communication and an increased amount of supportive behavior. Once the members have gained more self-confidence in doing their tasks the leader may use a supportive style. This style consists of shared decision-making and two-way communication. Finally, in a situation where the members are mature and self-confident the leader should use a delegating style. In this style the leader allows the members to decide how, when, and where to carry out their tasks. The next and final step is to organize your followers. When trying to do this, leaders should use six steps. These steps include: 1. Clearly articulate the vision and mission of your organization, 2. Develop a statement of your organization’s philosophy regarding volunteer services, 3. Develop volunteer positions, 4. Do not go overboard by creating a multitude of tasks, 5. Reward both process and outcome, and 6. Develop a nurturing Islamic organizational climate. The book also discusses how leaders should be able to delegate tasks. When a leader is reluctant to delegate there are usually two reasons for it. The first reason depends on the organization’s culture. The second reason has to do with the leader’s personality, usually dealing with a Type A personality. There are delegation guidelines that are outlined in the book. these guidelines include: selecting the delegate with the appropriate skill level, expertise and background, select a delegate with whom you have a reciprocal trusting relationship, delegate both the pleasant and the unpleasant, the easy and the challenging, delegate ahead, delegate in chunks, delegate precisely, delegate don’t abdicate, and finally give credit. According to the text, there is one golden rule when it comes it delegation, which is â€Å"the more power you give way the more power you have. †

Effects of

Marina Less, an 18th century female writer, gets plenty of fan mail, yet she only rarely replies. She feels compelled to answer to one woman in particular, Pierce, an older female dreaming to be a writer. Less' inspires Pierce by relating to her in many ways. Being a female writer in (1866), she appeals to her character and credibility by sharing personal experiences and shared values. She also informs Pierce about the qualities that she herself has that helped her to succeed.Time and wisdom is what Less feel is necessary to become a successful writer. By making a personal connection between the two women, Less is able to tell Price what it takes. The most important qualities that Less says are needed are wisdom and experience. With that being said, one gains wisdom through experience- you cannot make your writing believable without it. Using loaded words such as â€Å"genuine, trashy, and unripe†, Less expresses the importance of waiting until you have been more fulfilled in life. Less also appeals to Pierce's emotions by â€Å"stooping to her level† to con next more strongly with Price.In this way, Price will take Less' advice more to heart. Because this letter is written in 1866, the reader is lead to imply that women had very little rights. Women were given no respect in general, much less while being a woman author. Still today is the 21st century; women authors are using pen names so that their readers will see them as equals. They feared their male readers would not want to read her books because she is a woman. Considering all of this plus the time period, Price is at a disadvantage. In order to connect to on a more intimate level, Less uses feminism to unite their goals in a world run by men.Less reassures Price that even though she is a woman and although she is monotony she can still do whatever she puts her mind to. Although the reader is unaware of Pierce's writing abilities, Less feels confident in her and uses her own credibility to relate the two writers together in order to boost Pierce's confidence as a writer. Informing Pierce of their common ground, Less' persuades her by tapping into her emotions. Because she feels compelled to respond, she also succeeds in motivating Pierce by using rhetorical schemes such as personal experience and the two women's shared values.
