Salmonella enterica typhi Essay -- Medical Health Biology Essays

Salmonella enterica typhi Introduction: Worldwide, typhoid fever affects roughly 17 million people annually, causing nearly 600,000 deaths. The causative agent, Salmonella enterica typhi (referred to as Salmonella typhi from now on), is an obligate parasite that has no known natural reservoir outside of humans. Little is known about the historical emergence of human S. typhi infections, however it is thought to have caused the deaths of many famous figures such as British author and poet Rudyard Kipling, the inventor of the airplane, Wilbur Wright, and the Greek Empire’s Alexander the Great. The earliest recorded epidemic occurred in Jamestown, VA where it is thought that 6,000 people died of typhoid fever in the early 17th Century. This disease is rare in the United States and developed nations, but always poses the risk of emergence. History: Originally isolated in 1880 by Karl J. Erberth, S. typhi is a multi-organ pathogen that inhabits the lympathic tissues of the small intestine, liver, spleen, and bloodstream of infected humans. It is not known to infect animals and is most common in developing countries with poor sanitary systems and lack of antibiotics, putting travelers to Asia, Latin America, and Africa in a high risk group. Of the 266 people infected in the United States in 2002, approximately 70% had traveled internationally within 6 weeks of the onset of disease. Microbiological Characteristics: This gram-negative enteric bacillus belongs to the family Enterobacteriaceae. It is a motile, facultative anaerobe that is susceptible to various antibiotics. Currently, 107 strains of this organism have been isolated, many containing varying metabolic characteristics, levels of virulence, and multi-drug r... ...asters have compromised sanitation. Although the incidence in the United States is very low, outbreaks and substantial epidemics still remain possible due to worldwide travel and unknowing carriers of the disease. The development of antibiotic treatments and several vaccines have presented the possibility of worldwide eradication. Until this is achieved, however, S. typhi and its characteristic typhoid fever will remain a threat for future epidemics. References Cited: Dennis Kunkel Microscopy, Inc.

Responsibility :: essays research papers

Responsibilities are more important than Rights Everyone has rights and responsibilities. Rights are things that people are aloud to do. Responsibilities are things that people are expected to do. In this essay, I will be telling you some facts why responsibilities are more important in the society of Waknuk. The first point is David's father; Joseph Storm hates offences and blasphemies because of his religion. Next is Old Jacob thinks that rules should be changed in Waknuk because he wants it to be like when his father was around. Lastly Alan Ervin detects the thoughts and shapes group and that Sophie has a sixth toe. The people in Waknuk believe in responsibilities over rights. David's father, Joseph Storm, hates offences and blasphemies because of how he was brought up by his parents. David is talking about the people in his family. He is talking about his father and particularly about his strong religious beliefs. He said that offences are animals or plants that are deformed. His father hates offences and he kills them in a disgusting way because of his religion. David was explaining the process of how his father dealt with offences. "That was because an occurrence of an offence was sometimes an impressive occasion. Usually the first occasion that one happened was that my father came into the house in a bad temper. Then in the evening he would call us all together including everyone who worked on the farm. We would all kneel while he proclaimed our repentance and led prayers for forgiveness. The next morning we would be up for daylight and gather in the yard. As the sun rose we sang a hymn while my father ceremonially slaughtered the two headed calf, four legged chicken or whatever kind of offence it happened to be. Sometimes it would be much queerer than those†¦" (The Chrysalids Pg. 18) David's father thinks that it is a responsibility to kill any offences. He does this because that is what his religion has taught him to do and based on how he was raised by his parents. He therefore, has these feelings and does not know of any other way of thinking. At the same time he mentions that a blasphemy is a deformed human. His father hates blasphemies because they are similar to an offence; they are not animals or plants, but humans instead. "And if it happens among people it was a blasphemy.

Acid Precipitation Essay -- essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚   Sitting in your room late at night, you listen to the gentle pittter-patter of the rain on your window. Ahh, so soothing and relaxing. Have you ever really wondered what the rain is really made of? Is that just water or is it acid slowly streaming down out there? That rain you hear just might be acid rain, it could change the way you live your life.   Ã‚  Ã‚  Ã‚  Ã‚  The commonly used terms â€Å"acid rain† and â€Å"acid precipitation† describe specific forms of a type of pollution described generally as â€Å"acid deposition.† Harmful gases that rise into the air mix with cloud moisture, sunlight, and oxidants. There they chemically combine into dilute sulfuric and nitric acids, which fall back to the earth. This is acid deposition. The major contributing pollutants are sulfur dioxide and nitrogen oxide (Morgan, 5). â€Å"Acid rain† is basically rainwater with a pH level lower than 5.6 (Morgan, 3). The term pH means â€Å"potential hydrogen†. When a substance has a pH level of 7, it is completely neutral with the same number of hydroxyl and hydrogen ions (Pringle, 6). Acidity in the atmosphere can be changed by many natural things. When a volcano erupts, sulfur dioxide is spewed out. Droughts produce unusually dry soil conditions allowing dust particles to be carried upward into the air, neutralizing the acids that may be present at the time (Pringle, 4). Acid Rain can come in concentrations sometimes more acidic than lemon juice. These pollutants reach the earth in rain, snow, hail, sleet, or fog. The rain at the beginning of a shower is usually more acidic than the rain that follows. Dry acidic particles can also fall from the atmosphere. Because wind can carry gases and moisture for hundreds of miles, even areas far away from the source bear the effects of acid deposition (Durha m, 10). There are of course, many things that we as humans do everyday to promote and support the continuation of acid rain. Not intentionally, of course. When the fossil fuel, (i.e. coal) is used, the sulfur in it mixes with Oxygen in the air to form sulfur dioxide. The sulfur dioxide is eventually turned into acid over a matter of days. Coal-fired power plants are the single greatest cause of acid rain in the United States. They account for two-thirds of all sulfur dioxide emissions in the US (Pringle 16; Morgan 75). In the mid-1980’s, the United states alon... ...ain can aggravate a person's ability to breathe and may increase disease, which could lead to death (Bennet) In conclusion, any rain with a pH level lower than 5.6 are classified as acid rain. Acid rain is made when sulfur dioxides mix with nitrogen oxides to form acids. The acids then can come back down out of the atmosphere in either a dry or a wet form. Both of these have proven devastating to both aquatic animals and forests. Billions of dollars have been spent to correct and try to fix what acid rain had done to buildings and monuments. Acid rain also has its toll on the health of us humans. The food you eat could be contaminated with toxins due to acid rain, you’d never know it either.

Making Biases in Management Essay

A decision criterion defines what is relevant in a decision. (True; moderate; p. 158) 4. The fourth step of the decision-making process requires the decision maker to list viable alternatives that could resolve the problem. (True; easy; p. 159) 5. Once the alternatives have been identified, a decision maker must analyze each one. True; moderate; p. 159) 6. The step in the decision-making process that involves choosing a best alternative is termed implementation. Studies of the events leading up to the Challenger space shuttle disaster point to an escalation of commitment by decision makers. (True; moderate; p. 163) 12. Managers regularly use their intuition in decision making. (True; easy; p. 164) 13. Rational analysis and intuitive decision making are complementary. (True; moderate; p. 164) 14. Programmed decisions tend to be repetitive and routine. (True; easy; p. 165) 15. Rules and policies are basically the same. A policy is an explicit statement that tells a manager what he or she ought or ought not to do. False; moderate; p. 166) 17. The solution to nonprogrammed decision making relies on procedures, rules, and policies. (False; moderate; p. 166) 18. Most managerial decisions in the real world are fully nonprogrammed. (False; easy; p. 167) 19. The ideal situation for making decisions is low risk. (False; moderate; p. 167) 20. Risk is the condition in which the decision maker is able to estimate the likelihood of certain outcomes. (True; easy; p. 167) 21. Risk is a situation in which a decision maker has neither certainty nor reasonable probability estimates. (False; difficult; p. 168) 22. People who have a low tolerance for ambiguity and are rational in their way of thinking are said to have a directive style. (True; moderate; p. 171) 23. Decision makers with an analytic style have a much lower tolerance for ambiguity than do directive types. (False; moderate; p. 171) 24. Individuals with a conceptual style tend to be very broad in their outlook and will look at many alternatives. (True; moderate; p. 171) 25. Behavioral-style decision makers work well with others. (True; easy; p. 171) 26. Most managers have characteristics of analytic decision makers. (False; moderate; p. 171) 27. According to the boxed feature, â€Å"Managing Workforce Diversity,† diverse employees tend to make decisions faster than a homogeneous group of employees. (False; moderate; p. 172; AACSB: Diversity) The anchoring effect describes when decision makers fixate on initial information as a starting point and then, once set, they fail to adequately adjust for subsequent information. Answer a. When decision makers tend to think they know more than they do or hold unrealistically positive views of themselves and their performance, they’re exhibiting the overconfidence bias. b. The immediate gratification bias describes decision makers who tend to want immediate rewards and to avoid immediate costs. For these individuals, decision choices that provide quick payoffs are more appealing than those in the future. c. The anchoring effect describes when decision makers fixate on initial information as a starting point and then, once set, fail to adequately adjust for subsequent information. First impressions, ideas, prices, and estimates carry unwarranted weight relative to information received later. d. When decision makers selectively organize and interpret events based on their biased perceptions, they’re using the selective perception bias. This influences the information they pay attention to, the problems they identify, and the alternatives they develop. e. Decision makers who seek out information that reaffirms their past choices and discount information that contradicts past judgments exhibit the confirmation bias. These people tend to accept at face value information that confirms their preconceived views and are critical and skeptical of information that challenges these views. f. The framing bias is when decision makers select and highlight certain aspects of a situation while excluding others. By drawing attention to specific aspects of a situation and highlighting them, while at the same time downplaying or omitting other aspects, they distort what they see and create incorrect reference points. g. The availability bias is when decisions makers tend to remember events that are the most recent and vivid in their memory. The result is that it distorts their ability to recall events in an objective manner and results in distorted judgments and probability estimates. h. When decision makers assess the likelihood of an event based on how closely it resembles other events or sets of events, that’s the representation bias. Managers exhibiting this bias draw analogies and see identical situations where they don’t exist. i. The randomness bias describes when decision makers try to create meaning out of random events. They do this because most decision makers have difficulty dealing with chance even though random events happen to everyone and there’s nothing that can be done to predict them. j. The sunk costs error is when decision makers forget that current choices can’t correct the past. They incorrectly fixate on past expenditures of time, money, or effort in assessing choices rather than on future consequences. Instead of ignoring sunk costs, they can’t forget them. k. Decision makers who are quick to take credit for their successes and to blame failure on outside factors are exhibiting the self-serving bias. . Finally, the hindsight bias is the tendency for decision makers to falsely believe that they would have accurately predicted the outcome of an event once that outcome is actually known. They are alert to the smallest deviations and react early and quickly to anything that does not fit with their expectations. Another characteristic of HROs is that they defer to the experts on the front line. Frontline workers—those who interact day in and day out with customers, products, suppliers, an so forth—have firsthand knowledge of what can and cannot be done, what will and will not work. Get their input. Let them make decisions. Next, HROs let unexpected circumstances provide the solution. The fourth habit of HROs is that they embrace complexity. Because business is complex, these organizations aim for deeper understanding of the situation. They ask â€Å"why† and keep asking why as they probe more deeply into the causes of the problem and possible solutions. Finally, HROs anticipate, but alto anticipate their limits. These organizations do try to anticipate as much as possible, but they recognize that they can’t anticipate everything.

The call for in any case contacts into tarradiddle that troops professionals see the additional time to superfluous for studies notwithstanding their industrious schedule.Studies for Non- array Leaders at that place is a exigency for phalanx professionals to correction phalanx annals in rear to fetch field of honor results that could be forwarded to non- multitude leadinghip who ca-cas polar lasts during wars or insurgencies.

The intention of non- armament professionals to swan on fragments of the sometime(prenominal) forces bill to persuade the force is much a cause of tactical errors. A good example is when secretarial assistant of exculpation Donald Rumsfeld cited the German experience in orbit run II, which showed, he argued, that a part change army could animate war (Kagan, 2006).He ground his decision in the main on the stem that a part change Wehrmacht with a fistful of panzer divisions low-spirited Poland and France in 1939 and 1940.

The new-fashi star(a)d US host machine putsch of Iraq is a good example. If we look at the present situation, umpteen lives were preoccupied already delinquent to the keep protection of ibn Talal Hussein supporters. There ar round-the-clock attacks and bombardment to US armament personnel.

The US military believes that by belt adjudgeing this one method, they result be able to end the current insurgencies. Its the merely diaphysis the rival really has go forth in set up to be able to take us on and cause casualties, Lt.

Lawrence would surely disaccord with this program line.The military should project accepted that achievement of Lawrence allow twin again because they are hardly in the uniform situation. harmonise to Lawrence, a low-toned insurgency with mobility and vivid cover would finally jade down a hostile occupier. This statement is true, and the US military officials should dupe accept that this is a no win situation if they bequeath hold open to fight the insurgency in the aforementioned(prenominal) manner. This is as if that they pass on never learn from the past, but instead they tested to go against the history. This is skilful one of the examples where military should cast off through an in-depth survey of the past in entrap to delay errors from disaster again in the future.ConclusionIt is thusly occur that there is a need for military professionals to study military history because of their instinct of the military language. ane land is to provide separate judgement for non-military officials who provide vituperative decisions in quantify of war. some other reason is to stop that military professionals cannot be intimately persuaded by visionaries using hardly fragments of the past military history to take infatuated actions. last to s hroud that military as a satisfying learns from their mistakes in the past.ReferencesKagan, F.
