The Actions Of Vitamin D Other Than Those On Bone

Essay: Discuss the actions of Vitamin D other than those on bone. Abstract: Vitamin D (VD) is known to be involved in absorption of calcium in the gut with deficiency in VD playing a part in many bone related disorders like rickets and osteoporosis. Less known are the other beneficial health effects VD may have. VD has shown to have a positive effective on the immune system by not assisting the innate and adaptive immune response, but by also dulling the autoimmune response. This may be important in fighting disease like TB where VD deficiency is an issue. There also appear to be mechanisms that assist disease states such as cardiovascular disease, cancer and diabetes that VD may assist in however these studies are inconclusive and further study is required.  ¬Ã‚ ¬____________________________________________________________________________ Vitamins are essential molecules needed by the body for normal growth and development (Nlm.nih.gov, 2014). One such vitamin is the fat-soluble Vitamin D (VD) which assists in the absorption of calcium and exists in 2 forms, Vitamin D3 (VD3) and Vitamin D2 (VD2) (Nlm.nih.gov, 2014; Garg, Lubel, Sparrow, Holt Gibson, 2012). VD3 is primary sourced for humans is its synthesis in human skin, with 7-dehydroxycholesterol being converted to VD3 on exposure to UV light, usually from sunlight. VD3 can also be obtained from some animal sources like egg yolk or oily fish whereas VD2 is obtained from plant sources, with the VD referring to the summationShow MoreRelatedOsteoporosis Malady And Its Counteractive Action1627 Words   |  7 Pagess bones making them diminish in their thickness and be more powerless against crack.

Malaysia Response in Financial Crisis 1997 free essay sample

The Response for Malaysia during Financial Crisis in 1997-1998 If we went back to the dark ages of financial crisis in Asia, we should thank our forth prime minister Tun Dr Mahathir Bin Mohamad for the decision that he have done. When all of the Asian countries’ face this problem, some countries do response to solve the crisis. The traditional policy response to financial difficulties has been to seek assistance from the IMF for improving the situation. For such assistance the countries in trouble invariably have to undertake economic and financial reforms, impart more transparency to government spending, and make the necessary macroeconomic adjustments. They must initiate measures to revitalize their economic and monetary systems. Thailand and Indonesia took steps to remedy their weaknesses. Korea too joined in. But these countries soon found the crisis beyond their control, and decided to seek assistance from the IMF. Following the IMF conditions for the help, these countries had to implement tight monetary and fiscal policies, and had to enforce the prescribed structural reformations, particularly in the financial sector. The appointment of Tan Sri Nor Mohamed   Yakcop as Finance Minister II brought back to mind the innovative package of policy measures that Malaysia embarked upon in the dark days of the financial crisis of 1997-2000. The then Prime Minster Tun Mahathir Mohamed took the bold political decisions to introduce and enforce the measures. It was politically and technically a courageous act, as the policies flew in the face of orthodoxy and Dr Mahathir and Malaysia were condemned by the global establishment when they were introduced. Nor Mohammed is credited for explaining the mechanics of the international currency trade to Dr Mahathir and for working out the details and mechanisms of important parts of the policy package, especially the fixing of the ringgit peg to the US dollar, the selective foreign exchange controls and de-internationalisation of the ringgit. Today, the Malaysian measures are widely praised for being innovative and effective. The same International Monetary Fund that heaped skepticism on them has acknowledged that useful lessons can be learnt from the Malaysian experience. History will recognize the Malaysian measures as a landmark as they posed a systematic challenge and a practical alternative to the orthodox policies promoted by the â€Å"Washington Consensus†, or the group of powerful institutions like the IMF, the World Bank and the US Treasury. Many people today point to the Malaysian measures to show that alternative ways of resolving financial and economic crises are possible, do exist and can work even better than the orthodox policies. Malaysia was luckier than other countries affected by the crisis, like Thailand, Indonesia and South Korea. We were not in a debt default situation, and thus did not have to turn to the IMF for loans. Those countries had to obey the IMF, and lost their policy autonomy. The result was high interest rates, continued currency depreciation, and deregulation of foreign ownership that led to the foreign takeover of many local assets. Initially Malaysia also voluntarily took on IMF-type policies. But this did not work, as the high interest rates added to the corporate and banking crisis; the flexible exchange policy enabled the ringgit to depreciate (at one time almost touching five ringgit to the dollar);   the freedom of capital mobility allowed funds to flow out;   and the cutbacks in government expenditure added to recessionary pressures. In 1998, a year after the start of the crisis, the Malaysian model was introduced. This package comprised: * The core macroeconomic measures of interest rates, monetary and fiscal policies. Interest rates were significantly reduced, allowing firms and consumers to breathe again and then to borrow, thus improving investment and consumption conditions. The statutory reserve requirement was reduced to increase liquidity, and banks were encouraged to increase lending. And government boosted its spending, to get the economy moving again when the private sector was in the doldrums. These measures are consistent with the policies advocated by the great English economist John Maynard Keynes and are an integral part of Economics textbooks. They are taken by the US administration when the US is in recession. But they are forbidden to countries borrowing from the IMF, which has insisted on a combination of high interest rates, tight money flows, and government expenditure cuts. Thus ironically the Malaysian economic policies were seen as â€Å"radical† when they should be considered as standard Keynesian anti-recession policies. 1. Stabilising the exchange rate. The ringgit was fixed at 3. 80 to the US dollar, thus ending the previous flexible exchange rate system. This put an end to currency fluctuations and speculation. It allowed the macroeconomic policies to be implemented, and prevented a possible debt servicing crisis, which could have occurred if the ringgit had depreciated to below a certain level, as happened for example in Indonesia. 2. Closing down the overseas trade of the ringgit, and the trade in Singapore of Malaysian shares. This put an end to speculative activities in the currency and in local shares. 3. Regulating capital flows, particularly short-term capital outflows by foreigners and local citizens. Measures included an initial one-year moratorium on outflow of foreign portfolio capital and foreign-owned financial assets denominated in ringgit. Restrictions were placed on capital transfers by local citizens and companies. The restrictions did not apply to the flow of funds relating to foreign direct investment, nor to trade. These regulations were removed a few years later. 1. Maintaining financial stability by deciding on a policy of not closing down financial institutions facing difficulties, and announcing that the government would guarantee deposits placed in banks and finance companies. This prompted depositors to retain confidence in the banking system, unlike in other countries where bank closures (insisted on by the IMF) led to a run on the system and to capital flight. 2. Restructuring and recapitalizing the banking and corporate sectors to enable a recovery in the micro-economy. Among the measures were the establishment and work of Danaharta (an asset management company) to deal with the non-performing loans problem,   Danamodal (a special agency) to recapitalize troubled financial institutions and the Corporate Debt Restructuring Committee to restructure corporate debt 3. Revitalising the various economic sectors affected by the crisis. 4. Maintaining certain key economic and social policies, in particular the regulation of foreign ownership of assets, subsidies and price controls, policies relating to distribution and balance among local ethnic communities. If Malaysia had to turn to the IMF, it would have had to end many of these policies, and there might have been social chaos. But instead the country could continue to regulate the entry and degree of participation of foreign investors in the domestic economy. It could assist local firms and financial institutions facing financial difficulties. The policy of striving for balance in the distribution of assets and equity between locals and foreigners and among the local communities (the New Economic Policy) was basically maintained. Socially-oriented policies could continue, such as price controls on essential consumer items and subsidies on consumer items and to farmers. The government was also able to maintain its own policies on privatization, and on the extent and rate of financial and trade liberalization. Many countries taking IMF loans were pressurized to give up policies such as the above, and this led in some cases to social unrest. There are thus some important lessons from the Malaysian policy response to the crisis. Mainly, there are alternatives to the IMF policies. The Malaysian case shows that such an alternative approach exists, and can be applied in a relatively successful manner with good results. In addition, having policy space and flexibility is important to a developing country. The Malaysian experience also shows that if a country is able to avoid turning to the IMF, it can be free of being in the straightjacket of the IMF’s mainly one-size-fits-all policies, and can choose its own policies and also change them if they are found to be unsuitable. Other than that, a coherent anti-crisis strategy should be seen as an integrated package of its elements and policies. Policy makers sometime facing dilemmas and problems as there are multiple goals and the same policy instrument meant to achieve one goal definitely may give a negative impact on other goals. In fact, when there are many complex trade-offs happened, it is useful to apply the concept of â€Å"think outside the box† and seek new or extraordinary policy or solutions that might be available. In the Malaysian case, the various policy elements should be seen as parts of an integrated approach, or of a whole policy package. Thus, each element should be considered not only on its own merits or for its own role to achieve a particular goal, but also for its function of having an effect on another goal. A particular element or policy may not have the same successful intended effect, unless done together with some other element of policy. Thus, the inter-relationship of the elements and the interaction with one another should be appreciated. As example, reducing the interest rate was important for rescuing the micro economy and reviving the real economy; but doing so would have brought down the ringgit’s exchange rate and threatened the country with a debt default situation. The interest rate had therefore to be separated from the exchange rate. A new policy instrument—fixing the exchange rate—was then introduced. However, this step would have been not enough as speculation on the currency could still take place in ringgit offshore markets; and capital flight could also threaten the foreign reserves position and maintenance of the exchange rate would be unsustainable. During the end of 1997, ratings had fallen from investment grade to rubbish, the Kuala Lumpur Stock Exchange (KLSE) had lost more than 50% from above 1,200 to fewer than 600, and the ringgit had lost 50% of its value, falling from above 2. 0 to under 4. 57 on (Jan 23, 1998) to the dollar. Then, the hero of Malaysian, Tun Dr Mahathir Mohammad imposed strict capital controls and introduced a 3. 80 peg against the US dollar. Therefore, besides that, the stabilization of the currency also required two additional policy instruments—ending the overseas speculation by banning the currency’s trade abroad; and introducing selective capital co ntrols to regulate the outflows and inflows of funds. Therefore, beginning with even one major policy goal (reviving the local companies and the local economy) and a single policy tool (interest rate reduction), the Malaysian strategy also eventually involved several other policy tools and goals. On the other hand, to appreciate the brilliance of the Malaysian model, it is vital to see the role or roles played by each element, and to recognize that each of the measures was part of an integral policy package. Perhaps Malaysians are still too close in time and in geography to be able to distance ourselves and appreciate the full value of the Malaysian model. There were also many measures on the downside, such as the wastage in resources and inappropriateness of some of the rescue operations, especially in the big companies. These situations were heavily criticized at the time as cases of favouritism and cronyism and as a waste of public funds. In the past two years, Nor Mohamed played an important role in his position as Economic Advisor to the Prime Minister to rearrange the structure, ownership and management of several of the companies, and therefore helped in providing a better image to Malaysian citizen and corporate companies. The Malaysian crisis management strategy was the effect not only of one or two people but a team led by Tun Mahathir and comprising Ministers, the National Economic Action Council and its secretariat, and the key government agencies and Ministries. The Economic Advisor of Prime Minister, Nor Mohamed played a vital role mainly in the elements that involve the currency and the selective capital controls. For the public and citizen of Malaysia, they expect that the capabilities owned by Prime Minister and his team have higher potential and expectations that heir skills will be well used to properly leading the finances and economy of the country for the betterment in the future. What Can we Learnt from the Financial Crisis in 1997-2000 Despite of having the worst area of financial during 1997-2000, Malaysian citizen should be very thankful regarding the best decision made by the most powerful man of the country; the Prime Minister. If we can go back to the past, we can easily define the risk taking by our Prime Minister those days, Tun Dr Mahathir Bin Mohamad was a suicidal mission. Most of the countries that affected by the financial crisis will definitely seek for financial help and financial recommendations from IMF as they have no more idea. However, in Malaysias’ situation, we actually created a new solution that backs the roles of IMF itself. During those days, IMF was known and defined as the only solution that they have. For us, to be a leader for our country, determination and risk taking is ultimately important. Other than that, talking about lesson learn, especially in term of economic, the currency rate, and stock exchange do act as key roles for some country to excel in business and financial management. Nowadays, the country that not manipulate their currency itself and hoping 100% on IMF have a slow economic development. That is the only thing that makes us, as a Malaysian proud of our forth Prime Minister, Tun Dr Mahathir Mohamad.

Medieval parents virtually held absolute power over their children, especially their daughters as they were their parents possession from birth to marriage. Parents got their children married to whoever they chose, at early ages such as, 13.Wealthy parents got their children married to a prosperous and affluent person so, that they gained more respect and pride from the society. Parents expected their children to always be obedient, respectful and never disagree to their commands. Children in medieval times, had to do whatever their parents told them, whenever they told them. It was a harsh life for children compared to children today, who can do whatever they want, whenever they want .Todays parents let their children run their life in their own hands. Parents give their guidance, only if their children want to as children have their own independent lives, they chose who and when to get married. Parents today are cooperative compared to medieval parents who were strict. Below, I have explained some language devices Shakespeare has used in Romeo and Juliet, to show what the Capulets were like as medieval parents. In the scene Juliet disagrees to an arranged marriage to a wealthy man called Paris, Lord Capulet and Lady Capulet are extremely outraged as their verbal language shows how astringent medieval parents were. Shakespeare uses a range of ultimatums to interpret typical examples of medieval parents. For example, Lord Capulet frustratingly says to Juliet I tell thee what; get thee to the church OThursday; / Or never look me in the face and Gaze were you will, you shall not house with me. This illustrates the ferociousness of Lord Capulet, who will not accept Juliet as his daughter or allow her to live with him unless she agrees to marry Paris,who is very high class ad well known in the society. Medieval fathers brought enormous pressure on their daughters to marry the man he chose unlike parents nowadays would be more considerate to accept their childrens point of view. Mockery is another language device Shakespeare uses to emphasise the Capulets as traditional medieval parents. For example, Lord Capulet imitates her childish voice and says To answer, Ill not wed, I am too young, I pray pardon me to Juliet. Medieval parents neglected their childrens opinions and insulted them unlike parents today who are more supportive. The quote above demonstrates the fractious nature of Lord Capulet who assumes that Juliet is too young and too childish because she is refusing the good fortune offered to her. Another language device that Shakespeare employs to show the Capulets as typical examples of medieval parents is threatening language. Capulet shows impatience, while speaking to Juliet for example, Out, you green-sickness carrion! Out, you baggage/ You tallow face! . Green sickness-carrion is a double insult; it means she looks as green as something that has been dead for long and she is afflicted with sickness that comes from being a girl. Another example is, To go with Paris to Saint Peters Church/Or I will drag thee hurdle thither, Capulet is humiliating Juliet and threatening to drag her on a prisoners sledge to the church. These quotes show that medieval parents were extremely selfish and narrow minded unlike parents today who understand their childrens rights. A further device Shakespeare has used is rhetorical questions to portray the Capulets as medieval parents. Rhetorical questions were used to emphasise the Capulets outrage by Juliets dishonour for example, How, how, how, how, choppd logic? What is this? This argument is considered useless in Capulets mind. Another example is, Soft! take me with you, wife, How will she none? doth she not give us thanks? This emphasises that Capulet is astonished, he expected Juliet to thank him profusely and to be proud to be Pariss wife. This defines that medieval parents had strength over their children, who had no rights to do any on their chose. Nowadays children feel freer to choose their own paths without hesitation. Parents nowadays are more supportive unlike medieval parents who were very uncooperative. Shakespeare has used different language devices to imitate Capulets as medieval parents such as, uses of lists. The use of lists introduces the irritation of Capulets for example God breads makes me mad/ Day, night, hour, tide, time, work, play. This illustrates that Capulet worked really hard and spent a lot of time to find Juliet a husband but Juliet does not appreciate all he had done for her. Another list used in the scene was, And you be mine, Ill give you to my friend;/ And you be not, hang, beg, starve, die in the streets, this means that if Juliet does not agree to marry Paris, he will not accept her as his daughter and will not give her any support her, in her future life. Another language device Shakespeare uses to outline Capulets as a medieval parent is alliteration. Examples of alliteration were used when Capulets gets ill-tempered by Juliets imprudence and sarcastically says, Mistress Minion. This quotes that Juliet is a spoilt child. Another example used was Fettle you fine joints which means prepare for what you have ahead of you. The point that Shakespeare is making is that parents use to low grade their children and make them feel unwanted, unlike parents today who want their children to feel comfortable and wanted at home. Metaphors are another language device Shakespeare uses to display the Capulets as medieval parents. For example Lady Capulet irritatingly says to Juliet I would the fool were married to her grave .The point Shakespeare is making is that traditional medieval parents were very cold and unpleasant if they didnt get their way. The quote above means that if Juliet does not marry Paris the thing for her to do is die, her parents will feel shameful and deeply insulted if she rejects Paris, as Pariss family will no longer respect the Capulets. Shakespeare uses exclamation marks to indicate Capulets as medieval parents. For example Shakespeare uses exclamation marks to emphasise Capulets strong feelings such as, Hang thee, young baggage! disobedient wretch! This shows that Capulet was threatening Juliet by making unpleasant remarks. This shows that medieval parents did not think about there childrens feeling unlike parents today who understand their childrens feeling very well. In conclusion medieval expected too much of their children and didnt understand their feelings as they were treated in this way when they were children. Life was hard for medieval children; they had a lot to cope with unlike children today who are very enthusiastic.

Essay on How to Sell a House Fast in a Slow Real Estate Market

Essay on How to Sell a House Fast in a Slow Real Estate Market Essay on How to Sell a House Fast in a Slow Real Estate Market Essay on How to Sell a House Fast in a Slow Real Estate MarketWhen there is a need to sell a real estate property, there are two ways the seller can choose: sell the property on ones own or hire a real estate agent. Selling the property personally might be more efficient in terms of price and profit; however, this process will likely require a lot of time and effort. Hiring a real estate agent will increase sale costs, but this decision will help save time and resources (Bronchick Cooper, 2008). In addition, real estate agents have access to a wider pool of potential buyers compared to sellers selling on their own (Bronchick Cooper, 2008).The decision on whether to hire a real estate agent or not depends on personal preferences: the need to save money, the need to save time, real estate market awareness, awareness of legal regulations pertaining to real estate and experience in performing all necessary procedures associated with the sale. Assuming that the relocation will take plac e in 3 months, it is reasonable to suggest that the key priority will be time and the second priority will be money. Therefore, in the considered case it will be best to hire a real estate agent. However, it is necessary to remember that real estate agents might not always work in the best interests of a seller since their commission is often weakly related to the final sale price and timing (Levitt Syverson, 2007).In order to motivate the real estate agent to act in the sellers best interest, it is necessary to introduce appropriate incentives (Levitt Syverson, 2007). These incentives should be economically aligned with the sellers goals. In the considered case, the key objective is to sell the property within maximum 2.5 months (since time is also needed to prepare the documents and complete the sale). The second objective will be getting maximal price that can be achieved in the current situation.Therefore, the proposed incentives are the following. The agents commission should be divided into 8 parts: 2 parts are paid when the sale is completed (regardless of sale conditions), 3 parts are paid if the sale is completed within 2.5 months (so the agent is motivated to sell the house in time) and the remaining 3 parts are paid if the price exceeds a pre-determined level (which should be chosen slightly above average market rate) and takes place on time. In this case, the agent is strongly motivated to sell the house on time and is also quite motivated to sell the house at a high price, so he or she will act in the sellers best interests identified in this case.

Recent Developments in Undercover Policing Assignment

Recent Developments in Undercover Policing - Assignment Example Undercover police functions are a standard feature of contemporary political territory. Several secret revelations in recent days indicate that environmentalists, anti-nuclear and human & animal rights among other groups are likely to be the target of various surreptitious activities. Such activities can take any form, i.e. from the demonstration of supportive activities to training operations in specific organizations. The Ruckus Society is an example of one such organization, which is concerned with various defense activities. This organization delivers tools, training, and support to the environmental, human rights and social justice coordinators (The Ruckus Society, â€Å"About Us†). However, only negligible information has been available regarding the true motives of the organization, i.e. how they operate and how they support various activities among others. Thus, an infiltration has been planned in order to investigate the organization. Accordingly, two female detective s have been chosen in order to go to deep undercover as a part of their investigation. Contextually, when undertaking their investigative activities in The Ruckus Society, they need to maintain certain guidelines. The key objective of this assignment is to provide instructions to the female detectives when performing their duties as undercover agents. The assignment provides guidance for the female detectives in order to undertake investigation activities without compromising the undercover status. Fundamentally, there are two categories of an undercover operation that are categorized as deep cover and light cover. A deep cover infiltrator lives the role with widespread skills in undercover work. Deep cover operations are strongly compartmentalized in the investigation of an organization in order to prevent a breach of security or leak of information.

A history of ultrasound physics and the properties of the transducer Research Paper

A history of ultrasound physics and the properties of the transducer - Research Paper Example Prior to the second World War, sonar, which is the technique of transmitting waves of sound through water and observing the echoes that return to characterize the objects that are submerged, was an inspiration to the pioneers of ultrasound investigators in exploring ways and in turn applying the medical diagnosis concepts. This paper will highlight the history of ultrasound and discuss the properties of transducers. History of ultrasound According to Orenstein, (2008) Pythagoras, popular for his theory about right-angled triangles was the pioneer of ultrasound, since he invented the sonometer, which was used to study musical sounds. Boethius (c. 480-c.525) was the first to give comparison between sound waves to waves that were produced when a pebble was dropped into calm water. Pierre Curie, a French physicist discovered piezoelectricity in 1877, the moment that ultrasound was conceived. Later on, as Orenstein continues to assert, sonographic imaging was developed by French professor and physicist Paul Lavengin. Many scientists had the desire to see inside the human body and in turn developed probes and scopes for diagnosis and treatment during the late 19th and early 20th centuries. For instance, the discovery of X-rays by William Conrad in 1865 played an important role in the history of ultrasound. Moreover, in 1912, when the Titanic sank while on its maiden voyage made people to be curious in detecting submerged s ubstances. Like many other technological advances, ultrasound also owes its development to the World War. Lavengin was called upon by the French government to develop an object that was able to detect the sub marines of the enemy during the World War One. The device he invented applied the piezoelectric effect he had learned as Curies’ student (Orenstein, 2008). The transducer is one of the most critical componenets of any diagnostic ultrasound system. There exists various types of ultrasound transducers that can be chosen prior to performing an ultrasound investigation, therefore, much attention should be accorded towards choosing the most suitable transducer for the ultrasound application (Gibbs, Cole, & Sassano, 2009 p27). However, Lavengin did not complete the device he developed in 1917 so that it could be used during the First World War, but it indeed formed the basis of sonar detection that was developed in the World War II (Orenstein, 2008). In 1928, Sergei Sokolov, a Russian physicist made important suggestions that saw ultrasound being used for industrial purposes that included detecting flaws in metallic devices. Ultrasound is a new aspect in the field of medicine. For instance, in the 1920s and the 1930s, ultrasound was used by members of European football clubs as a physical therapy. Additionally, as reported by Orenstein, ultrasound was utilized in the sterilization of vaccines as well as for cancer therapy in conjunction with radiation therapy. Subsequently, in 1948, other ultrasound pioneers such as Douglas Howry subjected his efforts towards developing a B-mode equipment that compared pathology to cross-sectional anatomy. The late 60s and early 70s was the period of sonic boom. A 2D echo was pioneered by Klaus Bom. Don Baker, John Reid and Dennis Watkins were able to develop a pulsed Doppler in 1966, which was able to detect the flow of blood from the different corners of the heart. Real-time ultrasound was developed in

Miss Evers’ Boys portrays the emotional effects Essay Example for Free

Miss Evers’ Boys portrays the emotional effects Essay Miss Evers’ Boys portrays the emotional effects of one of the most amoral instances of governmental experimentation on humans ever perpetrated. It depicts the government’s involvement in research targeting a group of African American males (â€Å"The Tuskegee Experiment†), while simultaneously exploring the depths of human tragedy and suffering that result, as seen through the eyes of Eunice Evers. The viewer watches as a seemingly innocuous program progresses into a full-blown ethical catastrophe—all the while taking Miss Evers through a moral journey, with her decisions having ramifications on the life and well-being of her best friends—her â€Å"boys. † I. Structure This movie deals with the ethical considerations present in human experimentation. The government, wanting to mimic the Oslo Experiments, intends to study a population of AfricanAmericans inflicted with syphilis. The movie takes place in alternate settings, transitioning between a 1973 Senatorial hearing and the site of the actual study in Alabama, beginning in 1932 and moving forward. Miss Eunice Evers, a nurse at a local Tuskegee hospital, is the centerpiece of the movie. II. Setting Plot Summary With an ominous lead-in quote, Miss Evers’ Boys begins to tell the tale of an emotionally courageous young woman and her struggle to protect her â€Å"children. † Within the first few frames  of the movie, the viewer is automatically entrenched into the already tenuous history of racial tension in America—except, this time, under the auspices of segregation founded upon disease. The movie begins, placing the viewer as an observer of a 1973 U. S. Senate Hearing, where we are first introduced to Miss Eunice Evers. Miss Evers is testifying as a nurse, one who took the nurse’s oath to protect the health of those in her care. The claimed Senatorial goal is to discover the truth underlying the â€Å"Tuskegee Study. † Miss Evers worked in the study from 19321972. The movie progresses throughout the course of the hearing, with testimony by Miss Evers and reminiscent scenes telling the tale of the study. In the beginning, Miss Evers firmly supports the goal of the initial plan—to provide care and treatment to those suffering from syphilis. â€Å"It was the dawn of a new day,† explains Miss Evers. At this point (pre-study), she believes that the government is sending her patients, and her city, the best funding and medical support available. The viewer is then introduced to Miss Evers’ Boys—a folk music group. 1 The musicians (four of them) are the first patients to provide blood samples, one of them being Caleb, an eventual love-interest of Miss Evers. Each of the men test positive for syphilis. At this point in the movie, everyone (including Miss Evers) is still under that assumption that â€Å"bad blood† is the culprit for the disease. Ultimately, the funding for the initial study disintegrates. After a visit to Washington, various gentlemen confront Dr. Brodus, the head doctor in Tuskegee, with an offer for a new rationale for funding. The gentlemen explain their intentions of studying the African-American population, much like the Caucasian population in the Oslo Experiments (1891-1910). The government then reveals the true nature of the experiment—the proposed study of untreated African-Americans dealing with syphilis. 1 The government promises future treatment and The group names their band after Miss Evers when she drives them to their first musical show. 2 proclaims the future potential of the Tuskegee Experiment, appealing to Dr. Brodus’ pride. Dr. Brodus agrees, naming the study, The Tuskegee Study of Untreated Syphilis in The Negro Male. 412 men, afflicted with syphilis, participate in the study. In a telling interaction involving one of the first patients, Miss Evers suggests that the doctors explain to the study group that they are providing â€Å"back shots. † Through her deceit, Miss Evers thus begins to involve herself in the â€Å"treatment. † The tension she feels manifests itself in her facial features; the viewer can see her apprehension in this instance and throughout the movie. She is torn, but yet continues to help Dr. Brodus conduct the study. As 6-months turns into years, Miss Evers continues to hide the secret behind the study. She urges the men to continue the study, in hope of future treatment—treatment that never comes, even through the eventual availability of penicillin. Miss Evers’ ultimate decision as to how she deals with the care and treatment of her â€Å"boys† will be left to the viewer. With the journey, however, comes a tumultuous story, exposing the hypocrisy of the United States Government through the eyes of Eunice Evers. Throughout the movie, as an audience, we want Miss Evers to defy all conventions and simply provide the necessary medicine to the patients. Yet, she struggles throughout with the pros and cons of such a decision. On one hand, she wants to support the experiment; yet, on the other, she wants to protect and comfort her friends. As we finally see in the end, as seen through Miss Evers’ unique perspective, while one may question Miss Evers, it is the Senators themselves, and the government agents before them, who prove to be more worthy of moral appraisal.
