Cholera Essay examples -- Vibrio cholerae Infection Disease

Cholera The disease, cholera, is an infection of the intestines, caused by the bacterium Vibrio cholerae. As stated in Microbes and Infections of the Gut, the bacterium is â€Å"a Gram-negative, comma- shaped, highly motile organism with a single terminal flagellum† (105). Cholera is characterized by the most significant symptom that presents with the disease, diarrhea, and victims can lose up to twenty liters of body fluids in a day. Cholera can be a serious disease, due to the serious dehydration that can occur, but it is only fatal if treatment is not administered as soon as possible. This research paper includes information on the causes of cholera, symptoms, ways of treatment, studies of treatments, complications that may occur, the tests and diagnosis for cholera, and finally, the ways the cholera bacterium may be transmitted. Introduction Cholera is a disease caused by the cholera bacterium Vibrio cholerae infecting the intestines. Usually, the illness is mild, and for some, symptoms of cholera never even present, but sometimes, the disease can also be severe. A severe case of cholera is â€Å"characterized by profuse watery diarrhea, vomiting, and leg cramps. In these persons, rapid loss of body fluids leads to dehydration and shock. Without treatment, death can occur within hours† (Cholera Symptoms, Causes, and Treatment). Normally, in a gentler case of cholera, the infected person only has mild diarrhea. â€Å"In 5-10% of cases, however, patients develop very severe watery diarrhea and vomiting from 6 hours to 5 days after exposure to the bacterium. In these cases, the loss of large amounts of fluids can rapidly lead to severe dehydration. In the absence of adequate treatment, death can occur within hours† (Cholera Symptoms, Ca... ...a Symptoms, Causes, and Treatment." MedicineNet.Com. 31 Aug. 2005. . 9.) "Cholera: Treatment."

Affirmative Action in Employing Women and Minorities :: Affirmative Action Equality Essays

Affirmative Action Thesis: Although many people believe that affirmative Action is a form of racism, it is actually used to help minorities find employment in an otherwise racist world. â€Å"In the United States, equality is a recurring theme. It has flared into a fervent moral issue at crucial stages of American history: The revolutionary and Jacksonian Period, and the New Deal. In each era, the legitimacy of American society is challenged by some set of people unhappy with the degree of equality† (Verba and Orren). Following the Civil War, Congress passed a number of laws designed to put former slaves on an equal level with white people. The Fourteenth Amendment made the freedmen citizen and prohibited states from enforcing any law which took away the privliges of any citizen, depriving men of life, liberty, or property without due process of the law, or denied men equal protection of the laws. In 1875, Republican majority in Congress, aware that reconstruction would soon e nd, passed a civil right act to secure by law semblance of equality for Black Americans (Urofsky 19). Many white Americans really did not like the idea of equality for the Black Freedmen. â€Å"Gideon Welles, who had been prevailing sentiment when he wrote in 1871: ‘Thank God slavery is abolished, but the Negro is not, and never can be the equal of the white man. He is of an inferior race and must always remain so’†(Urofsky 23). The supreme court agreed and in 1883 passed the Civil Rights act which diluted much of th! e protection of the Fourteenth Amendment. Justice Joseph Bradely interpreted the enforcement provision of the amendment as strictly remedial; â€Å"congress has the power to remedy a discriminatory state law, but could not take affirmative steps to protect blacks from other forms of prejudice† (Urofsky 21). As a result of this decision, the federal government took no action to combat racism in the country until the second world war (Urofsky 2 2). Because resentment continued to increase within the black communities and because of the threat of a march on Washington, President Franklin D. Roosevelt issued an executive order on June 25, 1941. This order directed African Americans to be accepted into job-training programs in defense plants. The order also stated that discrimination would not be excepted by employers holding defense contracts. It also set up a fair employment practice commissions to investigate charges of racial discrimination.

How did the Prohibition Change USA Essay

The word â€Å"Prohibition† as stated in the World Book encyclopaedia â€Å"refers to laws that are designed to prevent the drinking of alcoholic beverages.† The enforcement of the Volstead Act in the United States of America (USA) saw the nationwide beginning of the prohibition on the 16th of January 1920. The Prohibition brought about a change in attitude for the people of the United States (USA). It caused an extreme rise in crime; encouraging everyday people to break the law and increased the amount of liquor that was consumed nationwide. Overall this law was a failure because a law can not be enforced on a democratic society with out the support of a majority. The effect of this mistake (prohibition) lingered on American (USA) society for many years to follow. Before the Prohibition the people of the United States of America had high moral standards, were more conservative and in many ways experienced less freedom both socially and economically. Before the Prohibition period the crime rate was relatively low compared with pre – prohibition figures. There was a â€Å"78 percent increase in crime† from those crime rates that were recorded before the Prohibition. Alcohol consumption in pre – prohibition in years had begun to drop since 1910, however this may have been due to the fact that â€Å"between 1880 and the beginning World War One in 1914 many states had adopted†¦state wide Prohibition.† Before Prohibition occurred nationwide, the economic boom of the 1920’s (also known as the Roaring Twenties) had not yet taken place, therefore the changes in attitude amongst the people of the United states were not yet established, consequently pre – prohibition years were times of less social freedom, more conservatism and some would argue higher moral standards. Due to these higher moral standards some groups believed Prohibition was a necessary measure in the creation of a society free from evils and less tainted in the old ways – meaning a society where crime rates, poverty, and death rates would be considerably reduced, the idea was that this in turn would improve the economy and quality of life for the people of the United States of America. The Prohibition caused an extreme rise in crime and in many cases it encouraged everyday people to break the law. As moral standards within society declined and prohibited alcohol consumption increased crime rates  within society rose considerably. This was because in order for alcoholic needs to be met, everyday people were forced to break the law, going against the honesty and freedom once shared by the democratic nation. Crime rates within the United States of America rose a great deal during the Prohibition years, criminal activity rose to 78 percent above that of pre-prohibition rates as more and more people broke the law, whilst serious crimes such as murder and assault rose to nearly 13 percent above what it had once been. With the Volstead Act running its course a new market was created for â€Å"corrupt politicians and gangsters to give the public what they demanded -alcohol and plenty of it.† One of the main reasons for the increase in crime rates was due to lack of enforcement; this was because there weren’t enough Prohibition agents to enforce the laws which were being broken on such a large scale. â€Å"It was assumed that Americans would follow the requirements of the new Prohibition law and so only 1520 Prohibition agents were employed in 1920 †¦ the number climbing to 2836 in 1930.† This rise in the amount of Prohibition agents did not really help matters very much as people continued to rebel against the enforcement of the Prohibition and continued to break the law, finding more creative measures to get away with their violation of the Volstead Act, â€Å"many people hid their liquor in hip flasks, false books, hollow canes, and anything else they could find.† Nationwide liquor consumption increased during Prohibition years. In order for people who wanted to fulfil their alcoholic needs to do so they were forced to break the law. Alcohol consumption considerably increased within the first couple of years of nationwide Prohibition in the United States (USA). â€Å"The drinking of alcoholic beverages became an act of rebellion against authority from the beginning of Prohibition, especially among university students and flappers.† Alcohol consumption did increase over Prohibition years, â€Å"$40 million of liquor had been smuggled into the United States in 1924† alone and that did not include the amount of alcohol which people made illegally in their own homes, which was most likely consumed that same year as well. There was a decrease in the consumption of beer, because it had to be transported in large quantities, which made the substance difficult to hide, as a result prices of beer and other alcoholic substances which had to be transported in such large quantities skyrocketed.  Once this had happened people began to turn to the more concentrated forms of alcohol or â€Å"hard liquors†, which were a lot easier to transport and as a consequence they were cheaper. Due to the increase in consumption of more concentrated forms of alcohol, people got drunk much faster than in pre – prohibition years. Consequently there were more alcohol related deaths during the Prohibition, due to a rise in alcohol consumption, as people were being poisoned by alcohol that was highly concentrated and or poisoned. â€Å"Deaths from poisoned liquor rose from 1,064 in 1920 to 4,154 in 1925.† There are many views as to why the Prohibition failed. One of the main reasons was due to the fact that a law can not be enforced on a democratic society without the support of a majority. During the prohibition there were many people who opposed the alcoholic limitations placed on their lives, as a result of the Prohibition, with many individuals feeling this way more and more people began to rebel against the restrictions which had a hold on them, they began breaking the law in protest to the Volstead Act. â€Å"Prohibition did not achieve its goals. Instead, it added to the problems it was intended to solve.† â€Å"The results of the [Prohibition] are clear: †¦organized crime grew into an empire; †¦disrespect for the law grew; and the per capita consumption of the prohibited substance †¦ increased dramatically† the prohibition had been a failure. Some believe that perhaps if the Prohibition had have been better organised and powerfully imposed then the Prohibition of the USA would have been more of a success. However this was not the case and due to the mistake made through the enforcement of the Prohibition the moral standards of society were changed forever. Nationwide Prohibition ended on the 5th of December 1933. However the effect of this mistake (Prohibition) lingered on American (USA) society for many years to follow. â€Å"It was hoped that Prohibition would eliminate corrupting influences in society; instead, Prohibition itself became a major source of corruption.† After the Prohibition had ended many people had changed their attitude towards the government, as they believed that the government had become too involved in the personal lives of individuals through their enforcement of the Volstead Act of January 1920. The United States of America would never be the same again, the nation never returned to the way  things had been in the years prior to Prohibition. During the time of Prohibition the great decade of change occurred, which was known as â€Å"The Roaring Twenties† with it came Prohibition, one of the gravest mistakes ever made by an American (USA) government, this mistake saw society change in more ways than one. As a whole moral standards declined, disrespect for the law became evident and faith in government policies decreased. After the Prohibition there was a â€Å"Midwestern crime wave in 1934 [where], gangsters robbed hundreds of banks, kidnapped and murdered scores of people.† Due to these criminal offences by 1940 people became untrusting of immigrants and under the Smith Act immigrants were to be fingerprinted as people feared that these people may have been gangsters. Prohibition was a grave mistake which changed the United States. During the Prohibition years the mistake of the Volstead Act caused an extreme rise in crime; encouraging everyday people to break the law and increased the amount of liquor that was consumed nationwide. Within Society moral standards began to drop, people began rebelling against the laws put in place, and breaking the law was no longer regarded as such a heinous act. â€Å"The dishonesty and corruption that grew with †¦ [prohibition] made †¦ [US people] lose their respect for the law and for the people who were supposed to enforce it.† American (USA) society has never really recovered from the effects of Prohibition, it has never returned to the moral standards once held as a nation. On a whole the Prohibition was one of the greatest mistakes made in the USA during the 1920’s. Overall the Prohibition was a failure that should not have been enforced at all, let alone in a decade [The Roaring Twen ties] where rapid change was taking place on its own.

DuPont’s Divestiture of Conoco

DuPont began life in 1802, as a gunpowder manufacturer supplying the US Army under President Thomas Jefferson. The company had a long tradition of technological innovations in business and it continues to serve worldwide markets including food and nutrition; health care; agriculture; fashion and apparel; home and construction; and electronics. Among some of its inventions are nylon stockings invented in 1939, Teflon for pans, Kevlar for bullet-proof vests, stainmaster for carpets, the synthetic fabric lycra, and Dacron for clothing. In 1999 the company held a portfolio of 2000 trademarks and brands. DuPont was the 15th largest company in the US with its 1998 revenue reaching $45. 1 billion. The company operated 200 manufacturing and processing facilities in 65 countries with 98,000 employees worldwide. Conoco began in 1875 as the Continental Oil and Transportation Co. , one of the first petroleum marketers in the West. The company has made it through plenty of tough and challenging times from the stock market crashing just a month after Conoco took its stock public, to overseas expansion, to the oil crisis of the 19070’s. Then in 1981 a simple proposal by Canada's Dome Petroleum about acquiring a Conoco subsidiary, Hudson's Bay Oil and Gas left the company wide open. In order to assure an adequate supply of petroleum products to use as chemical feed stocks, DuPont bought Conoco on Sept. 30, 1981. Conoco became a wholly owned DuPont subsidiary in the largest merger ever at that time, costing DuPont $7. 8 billion. As a subsidiary of DuPont, Conoco became a major, integrated, global energy company operating in 40 countries worldwide. The company was involved in both downstream and upstream activities like exploring for, developing, refining, marketing, transporting, and selling crude oil and natural gas. In 1998, Conoco ranked 8th in worldwide production of petroleum liquids by US companies, 11th in natural gas production, and 8th in refining throughput. In 1997 both DuPont and Conoco planned to pursue new corporate strategies: DuPont wanted to transform into a life sciences company focused more on biotechnology and less on petrochemicals, and Conoco desired financial independence to make significant foreign asset investments. While part of DuPont, Conoco doubled its value between 1986 and 1996, and realigned its assets. By late 1998, DuPont divested Conoco in a two-step process. First it would sell a minority stake in Conoco through an IPO otherwise known as an IPO carve-out. Then it would execute a spin-off and sell the rest of its ownership interest in the subsidiary at a later time. Under the split-off, DuPont shareholders would be given the opportunity to exchange their DuPont shares for shares in Conoco at a predetermined ratio of 2. 5 to 1. Participation in the exchange rate would be completely voluntary. On October 22, 1998 the Conoco IPO netted $4. 4 billion for 30% of Conoco culminating in the largest IPO in history. Then on August 9, 1999 the swap of DuPont stock for Conoco stock was finalized. DuPont secured about $21 billion in after tax value through the IPO and stock swap. I think DuPont’s two-stage divestiture worked the best because the company was able to make the transaction tax-free at both the corporate and personal levels. This basically means that DuPont sold off shares of Conoco in two separate stages. The company avoided the corporate capital gains tax by structuring the deal as a primary offering, which is the first of issuance of stock for public sale from a private company. Under this approach Conoco would sell new shares to the public and use the money from the offering to pay down an equivalent amount of its debt. If a second offering had been used, DuPont would directly sell a portion of its Conoco shares for cash, possibly creating a capital gains tax liability for itself if the sale proceeds exceeded its tax basis in the shares. The primary public offering of 25% of Conoco by DuPont was also good for shareholders because it met the objectives of maximizing shareholder value and it also allowed Conoco to capitalize on different investment opportunities for energy companies going on at the time. In order to make the second stage completely tax free DuPont had to satisfy a number of IRS rules and regulations. These rules stated that DuPont had to control Conoco immediately before the split-off, meaning that it had to control at least 80% of Conoco’s stock. In addition the split had to be motivated by a valid business purpose. Also DuPont had to get rid of all Conoco stock so it would not have any control over the company after the deal was completed. Conoco had to be recapitalized or reorganized into two classes of common stock. Class A stock that carried one vote each, issued to the public and Class B stock with five votes each, retained by DuPont for later disbursement to DuPont shareholders in the exchange offer. Prior to the IPO, Conoco would have to issue a $7. 5 billion promissory note to DuPont as a dividend. The payment would be tax free to both parties because at the time DuPont owned all of Conoco. Conoco would in turn, use the proceeds to pay back part of the note and other intercompany notes with DuPont. While I do agree with the Chief Operating Officer that a 100% IP of Conoco would raise a significant amount of cash to use in our core business growth internationally, allowing us to expand our global operations. I think the equity care-out was the best choice for DuPont to do instead of a complete 100% IPO. The reason I say that is because the deal still allowed DuPont to raise some capital but it also allowed DuPont to retain firm control of the subsidiary before, selling the remaining shares in a tax-free spin-off at a later date. A 1998 working paper from Pennsylvania State University examined 83 equity carve-outs done between 1981 and 1990, and found that carved-out companies had significantly higher revenue and asset growth, higher earnings, and higher capital spending than the industry average during the first three years after the carve-out–achievements, the authors say, that are a direct result of 80 percent of the deals tying executive compensation to the share price of the carved-out company at the time it goes public. â€Å"It's a way of providing a stronger incentive for subsidiary executives to perform,† says James A. Miles, one of the authors of the study, along with Heather Hulburt and J. Randall Woolridge. Parent companies also benefit from a carve-out. The Penn State study, in fact, found that these companies had a higher return on assets in the first year after the carve-out. And a similar study by J. P. Morgan & Co. , which examined 101 carve-outs between 1986 and 1997, documented that, on average, the share price of the parent rose between 3 and 4 percent in the 90 days following the announcement of a carve-out. The company’s ownership of Conoco has added great marketing and purchasing clout to DuPont’s operations just like the Executive VP for Research and Development and Product Development suggests, but again I don’t think that owning a majority share would benefit the company like getting rid of all ownership would do. The decision to retain majority ownership, however, may limit the upside to the deal. The J. P. Morgan study found a distinct difference in the share price performance of carve-outs that later became spin-offs and carve-outs that did not. In the case of 12 carve-out companies in which the parent announced there would be a later spin-off, the share price of the carve-out performed 11 percent above the market 18 months after the initial public offering. The shares of all other carve-outs–those without an announced spin-off later–actually underperformed the market by 3 percent. In closing I think DuPont did the right thing when they decided to go through with a two-stage divestiture of Conoco. I think they got the most bang for their buck by doing the deal this way. DuPont was able to net $4. 4 billion for 30% of Conoco resulting in the largest IPO in U. S. history. DuPont was also able to spin-off the rest of their shares of Conoco and secured about $21 billion in after tax value through the IPO and a stock swap. I think this was the best move because both companies were looking to go in different directions. DuPont wanted to transform into a life sciences company focused more on biotechnology and less on petrochemicals, and Conoco desired financial independence to make significant foreign asset investments.References: 1.

A personal visit ro a court in this semester - Article Example After the search, we were allowed to walk freely into the courtroom. I approached the receptionist and explained to her that my visit was part of my coursework, after which I was to write a report. She directed me to the six courtrooms available and told me to select one. I chose the first courtroom and sat at the public gallery with other members of the public who were there to watch the proceedings. Inside the courtroom, the public gallery was a portion at the back with stadium like seats.The barristers and solicitors sat in the middle area and the Judge in a raised box at the front.On the right was the defendant’s box and on the left was the claimant’s. I sat at the back facing the judge. The case in hearing was one about a stolen car. This case involved the claimant’s car was stolen from a parking outside a supermarket. The defendant on the other hand claimed he bought the same car legally from a local dealer. The claimant was the first to give an account of the events that led to the disappearance of his vehicle. He said that he had parked his car outside the supermarket and went inside to shop. After shopping, he came out only to find his car missing. He immediately rushed to the police station to report the incident. The car was found two weeks later driven by the defendant but under different registration. Soon after the claimant had finished narrating his ordeal, the defendant claimed he was not a thief and that he had just bought the said car from a local dealer. He presented all formal registration documents to prove he was the owner of the vehicle. The claimant’s barrister insisted that the defendant was aware that the car was stolen and participated in forgery of new documents. The defendant denied that and had to answer a series of questions from the claimant’s barrister as he was cross examined. After the defendant’s

Performance & reward mgt Essay Example | Topics and Well Written Essays - 1500 words

Performance & reward mgt - Essay Example It keeps the management aware of the importance of focusing on results rather than concentrating on whether the management or employees in an organization are busy. More over, it serves as a reminder of the fact that employee training, motivation and enthusiasm in the workplace are not sufficient for the accomplishment of organizational goals. In other words, Latham et al (2005) observes that results go beyond employee capacity and the level of satisfaction. They can be enthusiastic about their work, and the management may offer attractive packages that enhance satisfaction, but their output may not be satisfactory. This means that the organization may not be able to achieve the desired results. In order for an organization to accomplish its goals, it is important for it to have several operations taking place, such as classifying and giving priority to results, establishing the performance standards and the manner through which results need to be realized. Evaluation of progress is important while focusing on the results and also reviewing the manner in which they were accomplished (Facteau and Bartholomew 2001). Organizations use results as a measure for evaluating the performance of the business. A literature review concerning performance management is important in generating a better understanding of the concept. This paper describes a personal experience of performance management and analysis using concepts drawn from performance management literature. In many instances, organizational managers and overseers of organizational operations usually make a mistake of conceptualizing that the conduct of employees and the organizational operations are similar to the desired outcome. As Viswesvaran and Ones (2000) observe, employees within an organization may seem to be busy to a great extent, while in reality they do not add to the realization of organizational goals. Such cases are evident amongst employees
