Psychology Research Oral Presentation Hypothesis: Can sleep deprivation cause an increase in anxiety within medical students? Purpose of the study is to find a correlation between sleep deprivation and anxiety within Medical students Prediction: Sleep deprivation will cause a significant increase in anxiety of medical students Sleep disorders are particularly increasing in students as they face multiple stressors such as academic overload, constant pressure to succeed, and concerns about the future that alter the quality of their sleep Design: Using an Observational cross-sectional study: (definition data are collected during a single brief time period) during an academic year. To use questionnaires to find results.4 questionnaires would be faced to faced administered to students after obtaining written consent The 4 questionnaires were to measure their sleep quality and assessing Anxiety levels. Found to be the most common and effective questionnaires used in studies of sleep and anxiety The insomnia Severity index (ISI) Pittsburgh Sleep Quality Index (PSQI) Epworth Sleepiness Scale (ESS) Generalized Anxiety Disorder 7-item scale (GAD-7) Methodology: Questionnaire Survey Personal data about age, gender and faculty were collected. The ISI Is a 7-item self-report questionnaire. Assessing the nature, severity, and impact of insomnia. The evaluated domains are: Severity of sleep onset Sleep maintenance Early morning awakening problems Sleep dissatisfaction Interference of sleep difficulties with daytime functioning Perception of sleep difficulties by others Distress caused by the sleep difficulties. A 5-point Likert scale was used to rate each item (0 to 4 where 0 indicates no problem and 4 corresponds to a very severe problem), yielding a total score ranging from 0 to 28. The total score was interpreted as follows: absence of insomnia (0-7); sub-clinical (mild) insomnia (8-14); moderate insomnia (15-21); and severe insomnia (22-28). The PSQI Is a 19-items questionnaire evaluating sleep quality and disturbances The first four items are open questions, whereas items 5 to 19 are rated on a 4-point Likert scale. Individual items scores yield seven components: Sleep disturbance Overall sleep quality Sleep latency Duration of sleep Daytime dysfunction due to sleepiness Sleep efficiency Need for medicines to sleep A total score, ranging from 0 to 21, was obtained by adding the seven component scores. Some studies stated that a score 5 suggests a good sleep quality. The ESS Is a self-administered questionnaire with eight questions Each participant rated on a 4-point scale (0-3) his general level of daytime sleepiness, or the average sleep propensity in daily life. The total ESS score was the sum of eight item-scores and ranged between 0 and 24. The higher the score, the higher is the person's level of daytime sleepiness, with significant sleepiness when the score was 10 [24, 25]. GAD-7 Is a 7-item instrument that assesses generalized anxiety severity. Each item was scored 0 to 3, providing a 0 to 21 severity score (0-4: normal; 5-9: mild anxiety; 10-14: moderate anxiety and 15-21: severe anxiety Assessment of anxiety: Studying anxiety levels after periods of sleep deprivation In the case of total sleep deprivation only anxiety assessments acquired after 24h of lack of sleep were extracted. In the case of repeated measures, the first and the last available measures were always extracted; but intermediate assessments were only extracted if multiples of 12 (e.g., 36h, 48h). Operational Definitions: Sleep deprivation: sleeping less than the required amount of 8 hours before said time to wake up or class start A lack of sleep, which included total sleep deprivation (complete absence of sleep) Partial sleep deprivation (deprivation of one specific sleep stage, such asREM sleep) Sleep restriction (reduction in total time of sleep) Sleep fragmentation (intermittent awakenings through the sleep period). Taking account for the loss of sleep we also define insomnia Insomnia: the inability to sleep Anxiety: an overwhelming feeling of stress during upcoming tests or assignments as well as amount of course load Subjects: Randomly picking students under 3 faculties Medicine, Pharmacy and Dentistry Criteria: Inclusion: 18yrs and above and willingness to participate Exclusion: under 18yrs and presence of a chronic disease and history of Students were randomly selected For each of the studying the practice randomly selecting 1 male and female Studying the entirety of one semester Breaking it down from the beginning of the term to the midterm approaching and to final examinations Ethical Considerations: Informed consent

Free Essays on Why Catcher In The Rye Banned

Why the book was banned The Catcher in the Rye has long ignited disapproval, and it was the most frequently banned book in schools between 1966 and 1975. Even before that time, the work was a favorite target of sensors. In 1957, Australian Customs seized a shipment of the novels that had been presented as a gift to the government by the U.S. ambassador. The books were later released, but Customs had made its point that the book contained obscene language and actions that were not appropriate behavior for teenagers. In 1960, a teacher in Tulsa, Oklahoma, was fired for assigning the book to a 7th grade English class. The teacher appealed to the court and was put back by the school board, but the book was removed from use in the school. The following year in Oklahoma City, the novel became the focus of a legislative hearing in which a locally organized censorship group sought to stop the Mid-Continent News Company, a book wholesaler, from carrying the novel. Members of the group parked a 'Smutmobile' outside the capital building during the hearing and displayed the novel with others. As a result of public pressure, the wholesaler dropped the books from its inventory. In 1977 parents in Pittsgrove Township, New Jersey, challenged the assignment of the novel in an English class. They charged that the book included profanity that promoted premarital sex, homosexuality, and perversion, as well as claiming that it was explicitly pornographic and immoral. After months of controversy, the board ruled that the novel could be read in the advanced placement class for its universal message, not for its profanity, but they gave parents the right to decide whether or not their children would read it. The challenges to the novel have continued well into the 1990s. In 1991, the novel was challenged at Grayslake Community High School in Illinois for profanity, and students in Jamaica High School in Sidell, Illinois, cited profanities and the dep...

New Resources Tax in AUstralia ( MRRT) and it's effects on Australian Essay

New Resources Tax in AUstralia ( MRRT) and it's effects on Australian mining companies - Essay Example The Gillard Government’s proposed resource tax gained high approval from the International Monetary Fund, quoting it as a â€Å"step in the right direction.† Moreover, the MRRT would achieve the nation’s trust for consumption-based taxes and abolish ineffective taxation (Landers 2010). Because the MRRT is liable only to mining companies of iron ore, coal, oil and gas, there will be a reduction of the figure of affected companies from the previous 2,500 taxpayers to approximately 320 (Cherrington 2010). Taxpayers with annual income of no more than $A50 million will be exempted from the MRRT (Minerals Resource Rent Tax Regime n.d.) -The proposed MRRT promises an optimistic stride for mining investments in Australia. It offers a better guarantee for up-and-coming mining ventures, particularly those in the non-production of iron ore, coal, oil and gas. -For companies in mining ventures, the determination of taxable resource and revenues will be based solely on the nearest point to extraction as possible. This change would not deter the companies from their capital cost recovery and internal return rate. -The key adjustments from RSPT to MRRT in tax rates, particularly the 40% tax reduced to 22.5% rate and the resulting beneficial impacts on the projected efficient tax rates is forecasted to boost global competitiveness (Minerals Resource Rent Tax replaces RSPT 2010). The three pioneer mining companies in Australia: BHP, Rio Tinto and Xstrata equally agreed on a non-permission of the Australian tax to implement a target that could impact their multi-national operations. Their joint apprehensions over fluctuation on international shares and financial markets, whereupon loans are made to fund their projects, strengthened their vigilance on impending tax hikes by the government (Head 2010). The government negotiated exclusively with the

Watergate Scandal Essay Example | Topics and Well Written Essays - 750 words

Watergate Scandal - Essay Example Edward M. Kennedy and a young woman’s death. Remarkable of this incident is that it engulfed the U.S President Richard M. Nixon and many of his followers in an array range of illegal acts and hence triggered the resignation of the president who ended as â€Å"one of the sorriest spectacles in [U.S] national experience,†1 as a journalist from the New York Times put it. According to many investigations, the burglary has been carried out by five men who were later captured in the Democratic National Committee Watergate hotel. This serious incident garnered little media attention, yet it should be pointed out that two dedicated reporters, Bob Woodward and Carl Bernstein, both of whom were working for the Washington Post played, particularly, critical roles and managed somehow to uncover the president’s sponsored plan of espionage to discredit Democratic candidates. In addition to the reporters, another man called Sussman was directly involved in the Post’s effort to reveal and unveil the truth in the face of the general apathy by the press and the public and the White House pressures. Sussman cleverly remarked that the mass media, namely the press, was just not much concerned with the Watergate issue at the very beginning; however, the Post did its best and utmost to unearth the scandal. Sussman added that even the Congress repeatedly attempted to avoid if not ignore the Watergate Issue. He wrote that an â€Å"overwhelming number of congressmen had consistently turned their backs on Watergate until it surrounded them. They were still reluctant to deal with it, hoping Nixon would solve what was becoming their dilemma.†2 No doubt the Watergate scandal aroused considerable interest in how scandals are covered and oftentimes uncovered by the mass media. Of course, none can deny that the whys and the wherefores of Watergate have been widely investigated as many scholars conducted serious investigations and surveys about it. We can mention, in this

Reflection Paper Essay Example | Topics and Well Written Essays - 1250 words - 11

Reflection Paper - Essay Example He compares the softness of the moving ship over the water surface to a soft and beautiful skin. However, other characters such as Ahab consider the ocean as deceptive because, under the smooth waters, there lain death in waiting. Ahab acknowledges the fact that the sea in reality is a tiger under the surface. The ocean is, therefore, more dangerous than the land. According to Ahab, the sea is a mirror of God, and it represents Him as hidden and terrible, whose nature is deadly. Starbuck looks at the ocean and God as a bride at her wedding. The professor got me thinking of the reason for Christmas was a new beginning, yet inverted. For instance, Ahab thinks of the sea as a revenge because that is what he was up to during the journey for religious quest. The sea is therefore a revenge, not healing as quoted in line 536 (Melville 450). â€Å"†¦..Loveliness unfathomable, as ever lover saw in his young bride’s eye!—Tell me not of thy teeth tiered sharks, and thy kidnapping cannibal ways. Let faith oust fact; let fancy oust memory; I look deep down and do believe.†(Melville 451). Ahab asserts that the sea is too ambiguous and vicious for coherent faith, with our attraction to it infinite and unexplored. There are two things I noted out of these words, first the fact that God is inexplicable and second that religion is a faithful expression. For this case, the people at sea are trading a religious journey in which everything is a duality. Death lingers in lives of individuals, which kept me thinking about the whiteness of the whale. After a reflection on the readings, I discovered that such a question would be a distinction between good and evil according to our perception. Why were the whales both white and black? Why use the sea and not land? The answer lies in the nature of duality of religion. Sometime before birth, in the beginning, there is always the light that is the blinding light representing the

Stakeholders In Singapore Education Education Essay

Stakeholders In Singapore Education Education Essay Education is an area of great importance in Singapore. Thus, most parents have very high expectations of educators. In this essay, I will talk about what are some of these expectations and how I can harness them as a force to enhance students learning. The traditional expectation of an educator is that he must be responsible for the academic welfare and/or excellence of the child. Do parents also expect teachers to play a part in developing the whole person, in areas such as character development? Discipline, must then be part of character development. How much do parents agree to the whole person development? To what extent do parents want teachers and schools to discipline their children? What methods are acceptable and which are not? Recent events shed some light to the amount of expectation there is of schools and teachers and raises some interesting questions too. The Nan Chiau fiasco for example shows the expectation of the public of school discipline and in particular corporal punishment. It is difficult to bridge the gap between those who agree to what the principal did and those who did not. They did however agree to the basic tenet of discipline but not the style. This highlights to us the changes in societal views on methods of discipline. Do these changes in expectation restrict us in achieving our goal in developing the whole child? How do we work with these changed expectations Increasingly, parents are expecting to play a more active role in schools in the form of Parents Support Groups (PSG). In these committees, they may take on different projects and be in charge of their organisation. These projects can be in the form of enrichment programmes for students which may help in the disciplining if appropriate programmes are organised. The issues related to increased parental involvement are legion. What are parents motivations? Will parents expect something in return for their services? What kind of incentives can school offer to encourage parents to participate? Will it lead to inequity? Parents might feel that if they do not contribute as much, their children will be disadvantaged. Will they then see the PSG as an added workload to themselves? Will it disadvantage those students who come from a poor family background Methods to harness them as a force There are some possible solutions in the bid to harness parental support as a force. Schools can package the services that parents can offer. Since parents have different strengths and resources, they can contribute to schools in various ways, such as financial aid, time or talent. When seen in this way, parental support can be of great value to schools. In order to encourage greater participation in the PSG among parents, schools will need to market them. Schools need to be careful not to promote elitism by valuing certain skills above others. They need to ensure that parents do not feel that their contribution is insignificant. How can these be done? One proposal is that schools first identify the schools and parents needs and then communicate and match these needs. On a volunteer basis, parents who feel they can help may come forward to contribute. Schools can also explore the possibility of forming parent-parent groups instead of parent-teacher groups. This is to give greater autonomy to parents and to allow for self-regulation and organisation. It also saves teachers from extra responsibilities. As for questions pertaining to the organisation of the PSG, it has been suggested that cluster superintendents run them, so that they can come up with a model for the cluster of schools, instead of individual schools coming up with their own models. However, the drawback is that cluster superintendents are not at ground level, they do not really understand the actual situation of each of the individual schools. Different schools might have different needs, strengths and weaknesses with regards to parental support, willingness to be involved and resources that they can contribute. Cluster superintendents may then not be a good person to deal with the PSG. Principals have also been identified as a possible person to do the organisation. However, constant changes of principals make it difficult to establish a strong PSG. Also, there is the perennial problem of principals being overloaded with work. Beyond all these issues, we can see that it is important to harness parents expectation as a force to enhance student learning. In involving parents in school in various enrichment and discipline committees, parents will have some degree of control to meet their own expectations Teachers are a bridge between students and parents. We must find a way in which we can harness the negative energy of these parents and use it for beneficent purposes. The challenge for us teachers is to harness them in the correct manner. There are two possibilities to help remedy this. As the world changes, so do the families that make up the smaller blocks of society. Consequently, the second remedy is to heighten the awareness of these parents that the responsibility of their childs development does not fall solely on the shoulders of the teachers and the education system. We thus agreed that as teachers and educators, we must be acutely aware of these societal changes and react to them accordingly and hence the teacher group decided that teachers should be the bridge between students and parents. This is a relatively new trend in humanitys history. It is a reflection of the systems desire to acknowledge and incorporate parents as stakeholders in the education system, and allow these parents some say in how the school is being run . However, it must be cautioned that parental-teacher-school relationships should form a symbiosis for the benefit of students. Hopefully this will motivate them to create a more conducive environment for their children to develop and excel in. Most often this is due to the fact that parents now are better qualified and thus expect a lot more from teachers the education system and their children themselves. This highlights the issues of single parent families. All these factors play an important part in any childs educational process. The consequence of this is that the children of these dual income families spend less time with parents. In addition, the teacher group took into consideration the ubiquity of Singaporean households, where both parents work at their respective careers to provide for a decent standard of living in an increasingly costly city-state. Research has shown that parental involvement makes a differences in the future of the child. On the other hand, students whose parents are not involved are more likely to drop out of school. In conclusion, research has shown that the most accurate predictor of a students achievement in school is not income or social status, but the extent to which the students parents are able to: create a home environment that encourages learning; communicate high, yet reasonable, expectations of their childs achievement and future career; and become involved in their childs education at school and in the community.

A shot by shot analysis of a major scene in Hitchcocks Notorious :: essays research papers

The 3rd Major Scene in Alfred Hitchcock’s Notorious 1.  Ã‚  Ã‚  Ã‚  Ã‚  The scene begins by fading in on the back of the silent man’s head (Cary Grant) in Alicia’s bungalow. Then the camera zooms out while sweeping right to give the first full shot and view of both of the main characters. They are shown seated at a table, with many empty bottles of liquor and glasses. 2.  Ã‚  Ã‚  Ã‚  Ã‚  Then a tight reverse over the shoulder shot of Devlin’s face (Cary Grant) is next. Devlin then proclaims: â€Å"There's one more drink left apiece. Shame about the ice.† 3.  Ã‚  Ã‚  Ã‚  Ã‚  Next the shot reverses again to another tight over the shoulder shot but of Alicia’s face this time. Where she asks a question about what Devlin says. Devlin then answers her question about the ice when the shot is still on Alicia. 4.  Ã‚  Ã‚  Ã‚  Ã‚  Now the shot reverses again to a tight shot of Devlin’s face over Alicia’s shoulder. He then asks Alicia a question: â€Å"Why do you like that song?† 5.  Ã‚  Ã‚  Ã‚  Ã‚  Then the shot reveres again to an over Devlin’s shoulder shot tight on Alicia’s face. She begins to smile and laugh. Then Alicia gets suddenly serious and says: â€Å"There’s nothing like a good love song to give you a good laugh.† 6.  Ã‚  Ã‚  Ã‚  Ã‚  The shot reverses again to a tight over the shoulder shot of Devlin’s face where he answers Alicia’s question. 7.  Ã‚  Ã‚  Ã‚  Ã‚  Immediately reverses again to a tight over the shoulder shot of Alicia’s face, where she is shown yawning with her hand over her mouth.

Zombies

Zombies There is a current fad of entertainment in popular culture about zombies and zombie apocalypses. Have you ever heard of a real â€Å"Zombie†? Have you ever thought of where this idea of â€Å"Zombies† came about? Theyre history does not stem from Hollywood or comic books. Zombies have a real history as well as an actual scientific capability of existing. Isak Niehaus (writer for The Journal of the Royal Anthropological Institute) explained the cultural connection to zombies in Africa, and Wade Davis (writer for New York: Simon & Schuster) researched the reports in Haiti of he zombie culture there.Ker Than researched the topic for National Geographic news and came up with startling possibilities of a zombie-like outbreak. Just about everybody knows about fictitious zombies, but less are familiar with the facts about zombies. There are many people zombies are very real. They aren't a fable and are something to be taken seriously. Belief in magic and witchcraft is widespread throughout Haiti and the Caribbean, often in the form of religions such as Voodoo and Santeria.The Oxford English Dictionary, the term â€Å"zombie† initially showed up in English around 1810 when historian Robert Southey declared it in his book â€Å"History of Brazil. † But this â€Å"Zombi† wasn't the typical Hollywood version of the brain-hungry horror. Instead it was a West African deity. The word â€Å"zombie† later came to propose the human life force exiting the body, ultimately leaving a creature human in form but lacking self-awareness and intelligence. The word was introduced to Haiti and to other places from Africa through the slave trade.Isak Niehaus found that the term Zombie is used to describe a spellbound person deprived of cognizance and self- wareness, yet able to move and react to immediate provocations. Though many people treat the current â€Å"zombie apocalypse† as a fun pop culture meme, Haitian culture † li ke many African cultures † is greatly immersed in faith in magic and witchery. Belief in zombies is related to the Voodoo religion, and has been widespread in Haiti for many years. Haitian zombies were said to be people brought back from the dead through magical means by voodoo priests called bokors or houngan.Sometimes the zombification was done as punishment which struck fear in those who believed that they could be abused even after death. Often the zombies were said to have been used as slave labor on farms and sugarcane plantations. A mentally ill farmer claimed to have been seized captive as a zombie worker for two decades, though he couldn't show researchers where this had taken place. Researchers pursued a case in Haiti, 1937 of rumors that the affected persons were given a powerful psychoactive drug, but they were not able to locate anyone willing to offer much evidence.After many years the researchers concluded that there is more to Voodoo than ritual and that there is a medical base behind what is going on. Several decades later, Wade Davis, a Harvard ethno botanist, offered a pharmacological case for zombies some of his books. Davis went to Haiti in 1982 and, after investigations, claimed that a living being could be changed into a zombie by way of two specific powders being put into the circulatory system, most of the time by an open wound.One of the powders includes tetrodotoxin (TTX), a potent and often tatal neurotoxin tound in the putte The second powder consists ot dissociative drugs like datura. These powders could induce a deathlike state where will of the eing would be completely open to that of the bokor. Davis also popularized the story of Clairvius Narcisse, who was claimed to have succumbed to this practice. Davis described the case of an initial state of deathlike suspended animation, followed by reawakening into a psychotic state.The insanity induced by the drug and psychological trauma was hypothesized by Davis to strengthen s ocially learned beliefs and to cause the individual to rebuild their characteristics as that of a zombie, since they actually thought they were dead, and had no other role to play in the Haitian society. Though dead humans can't come back to life, certain viruses can induce such aggressive, zombie-like behavior, scientists say in the new National Geographic Channel documentary The Truth Behind Zombies.For instance, rabies, a viral disease that infects the central nervous system can drive people to be violently mad. If a rabies virus was to combine with the ability of a flu virus, in order to spread quickly through the air, you might have the makings of a zombie apocalypse. The first signs a human has rabies, such as anxiety, confusion, hallucinations, and paralysis ont typically appear for ten days to a year after infection, as the virus incubates inside the body. This is very unlike movie zombies, which become reanimated almost immediately after infection.Once rabies sets in, thoug h, it's fatal within a week if left untreated. If the genetic makeup of the rabies virus went through enough changes, or mutations, its incubation time could be condensed dramatically. Many viruses have naturally high mutation rates and constantly change as a means of evading or bypassing the defenses of their hosts. For the rabies virus to cause an event like a zombie pandemic, not unlike the ones ou might see in a movie, it has to be much more contagious.Typically a human could catch rabies after being bitten by an infected animal and the infection usually stops there, but thanks to pet vaccinations, people seldom get rabies in the U. S. nowadays, and even fewer people die from the disease. For example, in 2008 only two cases of human rabies infection were reported to the U. S. Centers for Disease Control and Prevention. A faster mode of transmission would be through the air, which is how the influenza virus spreads. The movie 28 Days Later depicts a scenario of a age virus. If ra bies somehow became airborne this movie would be very plausible.In order to be transmitted by air, rabies would have to mutate or use traits from another virus like influenza. Elankumaran Subbiah, a virologist at Virginia Tech, states that diverse forms, or strains, of the same virus can change pieces of genetic code using reassortment or recombination. Unrelated viruses, although, don't Just randomly create hybrids in nature. Likewise, he also said â€Å"They're too different. They cannot share genetic information. Viruses assemble only parts that belong to them, nd they don't mix and match from different families. It's theoretically possible for scientists to use a rabies virus and an influenza virus, though extremely difficult, to create a hybrid rabies-influenza virus using modern genetic engineering techniques. Sure, you could imagine a scenario where you mix rabies with a flu virus to get airborne transmission, a measles virus to get personality changes, the encephalitis viru s to cook your brain wit n tever and throw in the ebola virus to cause you to bleed from your guts. You would probably get something like the zombie virus, but nature oesn't let these things to happen all at the same time.Yet†¦ There is a vast history of zombies, from Africa to Haiti and other trade lands, all the way to Hollywood. The general focus of zombies is the entertainment of it all. To this day there are still cases of zombie voodoo and stories of dead people coming back from the grave. The focus should be on the possibilities of the future though. If Just one team of scientists with access to the means to hybrid existing viruses the entertaining idea of zombies on a TV would not be funny at all. It's not all that unreal now is it?

Expository essay Essays - Book Of Genesis, Hebrew Bible, Torah

Expository essay Essays - Book Of Genesis, Hebrew Bible, Torah Expository essay In this essay I will be explaining the bible verses Genesis 16, 18:16-33, 22:1-19. In the Bible it speaks on how God discovers that Abraham ought not be kept oblivious with respect to what God is "going to do" (18:17). God is worried that Abraham charges his relatives to "do honesty," that is, to do equity to the association with God in which they stand. On the off chance that Abraham did not do this, there would be no transmission of the confidence to the people to come and consequently no group to whom the guarantees apply. God's underlying words to Abraham (18:20-21) report the cries of unidentified people about the gravity of the wrongdoings of Sodom. God takes part in a legal request with Abraham, and God- - deciding to show Abraham the methods for equity - counsels with him in regards to the gravity of the circumstance in Sodom. God's utilization of the dialect of "if not" proposes that the fate of Sodom remains to some degree open, regardless of the possibility that God has to begin with chosen what to do. Abraham now remains before God and draws in God with respect to the circumstance in Sodom (18:22-33). He brings up sharp issues with God about the preparatory choice to obliterate the city. He is limit and determined, understanding that God invites such a test (such difficulties to God are additionally present in the mourns; for instance, Psalm 13). "Should not the Judge of all the earth do what is only?" (18:25b). Abraham is particularly worried that the noble in the city not be dealt with in an indistinguishable path from the devilish and brings the issue up in these terms: what number upright should there be in the city for God to spare it? God respects the question as an honest to goodness one. Abraham, for obscure reasons, begins with the number fifty and in the end works his way down to ten. God reacts emphatically to each question Abraham raises. While the numbers ought not be translated in an absolutely exacting manner, they raise the issue of "minimum amount." That is, what numbers of exemplary are important to spare the city from its own particular damaging ways? The development of mischievousness in any group can turn out to be so profound and expansive that there is a lacking number of honorable left in the city to turn the circumstance around. At the point when the number gets down to ten, Abraham perceives this to be the situation and leaves off the scrutinizing, perceiving that the pulverization of the city would be simply. Abraham continues to bring up particular issues about God's preparatory choice to pulverize Sodom in view of the objection against its subjects. The References "BibleGateway."

P-47 Thunderbolt in World War II

P-47 Thunderbolt in World War II During the 1930s, the Seversky Aircraft Company designed several fighters for the US Army Air Corps (USAAC) under the guidance of Alexander de Seversky and Alexander Kartveli. In the late 1930s, the two designers experimented with belly-mounted turbochargers and created the AP-4 demonstrator. Having changed the company name to Republic Aircraft, Seversky and Kartveli moved forward and applied this technology to the P-43 Lancer. A somewhat disappointing aircraft, Republic continued to work with the design evolving it into the XP-44 Rocket/AP-10. A fairly lightweight fighter, the USAAC was intrigued and moved the project forward as the XP-47 and XP-47A. A contract was awarded in November 1939, however the USAAC, watching the early months of World War II, soon concluded that the proposed fighter was inferior to current German aircraft. As a result, it issued a new set of requirements which included a minimum airspeed of 400 mph, six machine guns, pilot armor, self-sealing fuel tanks, and 315 gallons of fuel. Returning to the drawing board, Kartveli radically changed the design and created the XP-47B.

In response to the aircrafts weight, Kartveli commented,It will be a dinosaur, but it will be a dinosaur with good proportions. Featuring eight machine guns, the XP-47 featured elliptical wings and an efficient, durable turbocharger which was mounted in the fuselage behind the pilot. Impressed, the USAAC awarded a contract for the XP-47 on September 6, 1940, despite the fact that it weighed twice as much as the Supermarine Spitfire and Messerschmitt Bf 109 then being flown in Europe. Working quickly, Republic had the XP-47 prototype ready for its maiden flight on May 6, 1941. Though it exceeded Republics expectations and achieved a top speed of 412 mph, the aircraft underwent several teething problems including excessive control loads at high altitude, canopy jams, ignition arcing at high altitudes, less than desired maneuverability, and issues with the cloth-covered control surfaces. These issues were dealt with through the addition of a reward sliding canopy, metal control surfaces, and a pressurized ignition system. Additionally, a four-blade propeller was added to better take advantage of the engines power. Despite the loss of the prototype in August 1942, the USAAC ordered 171 P-47Bs and 602 of the follow-on P-47C. Improvements Dubbed the Thunderbolt, the P-47 entered service with the 56th Fighter Group in November 1942. Initially derided for its size by British pilots, the P-47 proved effective as a high-altitude escort and during fighter sweeps, as well as showed that it could out-dive any fighter in Europe. Conversely, it lacked the fuel capacity for long-range escort duties and the low-altitude maneuverability of its German opponents. By mid-1943, improved variants of the P-47C became available which possessed external fuel tanks to improve range and a longer fuselage for great maneuverability. The P-47C also incorporated a turbosupercharger regulator, reinforced metal control surfaces, and a shortened radio mast. As the variant moved forward, a host of minor improvements were included such as enhancements to the electrical system and a re-balancing of the rudder and elevators. Work on the aircraft continued as the war progressed with the arrival of the P-47D. Constructed in twenty-one variants, 12,602 P-47Ds were built during the course of the war. Early models of the P-47 possessed a tall fuselage spine and a razorback canopy configuration. This resulted in poor rear visibility and efforts were made to fit variants of the P-47D with bubble canopies. This proved successful and the bubble canopy was used on some subsequent models. Among the multitude of changes made with the P-47D and its sub-variants were the inclusion of wet mounts on the wings for carrying additional drop tanks as well as the use of a jettisonable canopy and a bulletproof windscreen. Beginning with the Block 22 set of P-47Ds, the original propeller was replaced with a larger type to increase performance. Additionally, with the introduction of the P-47D-40, the aircraft became capable of mounting ten high-velocity aircraft rockets under the wings and utilized the new K-14 computing gunsight. Two other notable editions of the aircraft were the P-47M and P-47N. The former was equipped with a 2,800 hp engine and modified for use in downing V-1 buzz bombs and German jets. A total of 130 were built and many suffered from a variety of engine problems. The final production model of the aircraft, the P-47N was intended as an escort for B-29 Superfortresses in the Pacific. Possessing an extended range and improved engine, 1,816 were built before the end of the war. Introduction The P-47 first saw action with the fighter groups of the Eighth Air Force in mid-1943. Dubbed the Jug by its pilots, it was either loved or hated. Many American pilots likened the aircraft to flying a bathtub around the sky. Though early models possessed a poor rate of climb and lacked maneuverability, the aircraft proved extremely rugged and a stable gun platform. The aircraft scored its first kill on April 15, 1943, when Major Don Blakeslee downed a German FW-190. Due to the performance issues, many early P-47 kills were the result of tactics which utilized the aircrafts superior diving ability. By the end of the year, the US Army Air Force was using the fighter in most theaters. The arrival of newer versions of the aircraft and a new Curtiss paddle-blade propeller greatly enhanced the P-47s capabilities, most notably its rate of climb. In addition, efforts had been made to extend its range to allow it to fulfill an escort role. Though this was ultimately taken over by the new North American P-51 Mustang, the P-47 remained an effective combatant and scored the majority of American kills in the early months of 1944. A New Role During this time, the discovery was made that the P-47 was a highly-effective ground-attack aircraft. This occurred as pilots sought targets of opportunity while returning from bomber escort duty. Capable of sustaining severe damage and remaining aloft, P-47s were soon fitted with bomb shackles and unguided rockets. From D-Day on June 6, 1944, through the end of the war, P-47 units destroyed 86,000 railway cars, 9,000 locomotives, 6,000 armored fighting vehicles, and 68,000 trucks. While the P-47s eight machine guns were effective against most targets, it also carried two 500-lb. bombs for dealing with heavy armor. By the end of World War II, the 15,686 P-47s of all types had been constructed. These aircraft flew over 746,000 sorties and downed 3,752 enemy aircraft. P-47 losses during the conflict totaled 3,499 to all causes. Though production ended shortly after the war ended, the P-47 was retained by the USAAF/US Air Force until 1949. Re-designated the F-47 in 1948, the aircraft was flown by the Air National Guard until 1953. During the war, the P-47 was also flown by Britain, France, Soviet Union, Brazil, and Mexico. In the years following the war, the aircraft was operated by Italy, China, and Yugoslavia, as well as several Latin American countries who retained the type into the 1960s.

HIV video summary - Assignment Example The first video proffered details of AIDS from the outbreak to epidemic. It discussed that AIDS was first reported June 5, 1981, when the U.S. Centers for Disease Control and Prevention recorded a cluster of Pneumocystis carinii pneumonia (now still classified as PCP but known to be caused by Pneumocystis jirovecii) in five homosexual men in Los Angeles. Acquired immune deficiency syndrome or acquired immunodeficiency syndrome (AIDS) is defined as a set of symptoms and infections resulting from the damage to the human immune system caused by the human immunodeficiency virus (HIV). More details on early epidemic signs, AIDS timeline, rapid AIDS virus test, global statistics, and question and answer portions were all presented. The mechanisms, from its inception to the life cycle of the virus were discussed. With the alarming number of people affected with AIDS, a specialized drug was developed to contain the syndrome. This is known as antiretroviral medications. â€Å"Antiretroviral drugs inhibit the reproduction of retroviruses-viruses composed of RNA rather than DNA. The best known of this group is HIV, human immunodeficiency virus, the causative agent of AIDS. Antiretroviral agents are virustatic agents which block steps in the replication of the virus. The drugs are not curative; however continued use of drugs, particularly in multi-drug regimens, significantly slows disease progression.† The enormity of people who had been diagnosed of AIDS/HIV in developing countries needs more than primary health care to address this illness. According to the video, the most appropriate care needed by patients diagnosed with AIDS/HIV is palliative care. By addressing the patients’ physical, emotional, mental, social, physiological aspects, health care practitioners could finally admit that appropriate treatment was indeed delivered. The lectures presented were very informative and useful as an authoritative

Interview on ethical dilemma part 2 - Essay Example She asserts that the Bible does not allow any form of human interference with human life. As such, death should not be voluntary or induced. The autonomy of a patient to choose his or her destiny as far as health is concerned fails to consider other interested factions. Thus, patients cannot decide to end their lives since repercussion run deep within the society. Euthanasia leads to wider social problems and introduces discomfort within a society. Families break due to differences in opinions regarding euthanasia. Family members of patients are required to consent to the move before it is done. In many instances, there is hardly consensus and only the decision of the patient and the majority of family members prevails. As such, the decisions leave a broken family. She further claims that different views in a family may result in depression and other health related problems. Parker accepts that patients have autonomy over their lives. She also accepts that there are many complex situations where patients suffer and have little chance of survival. However, there is no clear method to determine when to die, and whether a patient has the right to decide to stay alive or die. Some patients, especially parents or older siblings, are relied upon by children and other dependents for survival. As such, their decisions and actions directly affect others. It is important to stay alive since it gives hope to the dependents of possible healing. Ending the life of such individuals makes people lose focus and hope in life. Allowing people to decide their fate erodes the societal perception towards life. Society regards life as precious and supposed to be preserved at all times. Assisting people to take life communicates a wrong message to the society. Thus, it is imperative to treat the patient until he or she dies out of the severity of illness rather than assisting them to take their life. Doing so would
