Hypostatizationâ€Fallacies of Ambiguity and Language

Hypostatization- Fallacies of Ambiguity and Language The fallacy of Reification- Also known as  Hypostatization- is very similar to the Equivocation Fallacy, except that instead of using one word and changing its meaning through the argument, it involves taking a word with a normal usage and giving it an invalid usage. Specifically, Reification involves ascribing substance or real existence to mental constructs or concepts. When human-like qualities are attributed as well, we also have anthropomorphization. Examples and Discussion of the Hypostatization Fallacy Here are some ways in which the fallacy of reification can occur in various arguments: 1. The government has a hand in everybodys business and another in every persons pocket. By limiting such governmental pickpocketing, we can limit its incursions on our freedom.2. I cant believe that the universe would allow humans and human achievement just to fade away, therefore there must be a God and an afterlife where all will be preserved. These two arguments demonstrate two different ways that the fallacy of Reification can be used. In the first argument, the concept of government is assumed to have attributes like desire which more properly belong to volitional creatures, like people. There is an unstated premise that it is wrong for a person to put their hands in your pocket and it is concluded that it is also immoral for the government to do the same. What this argument ignores is the fact that a government is simply a collection of people, not a person itself. A government has no hands, therefore it cannot pickpocket. If the governments taxing of the people is wrong, it must be wrong for reasons other than a too-literal association with pickpocketing. Actually dealing with those reasons and exploring their validity is undermined by eliciting an emotional reaction by using the pickpocketing metaphor. This arguably means that we also have a fallacy of Poisoning the Well. In the second example above, the attributes being used are more human which means that this example of reification is also anthropomorphization. There is no reason to think that the universe, as such, really cares about anything- including humans beings. If it is not capable of caring, then the fact that it does not care is not a good reason to believe that it will miss us after we are gone. Thus, it is invalid to construct a logical argument which relies upon the assumption that the universe does care. Sometimes atheists create an argument using this fallacy which is similar to example #1, but which involves religion: 3. Religion attempts to destroy our liberty and is therefore immoral. Once again, religion has no volition because it is not a person. No human-created belief system can try to either destroy or build anything. Various religious doctrines are certainly problematic, and it is true that many religious people attempt to undermine liberty, but it is muddled thinking to confuse the two. Of course, it should be noted that hypostatization or reification is really just the use of metaphor. These metaphors become fallacies when they are taken too far and conclusions are formed on the basis the metaphor. It can be very useful to employ metaphors and abstractions in what we write, but they carry a danger in that we can begin to believe, without realizing it, that our abstract entities have the concrete attributes we metaphorically ascribe to them. How we describe a thing has a great influence on what we believe about it. This means that our impression of reality is often structured by the language we use to describe reality. Because of this, the fallacy of reification should teache us to be careful in how we describe things, lest we begin to imagine that our description has an objective essence beyond the language itself.

Seal and Sea Lion Facts

Seal and Sea Lion Facts With their expressive eyes, furry appearance and natural curiosity, seals have a wide appeal. Native to polar, temperate and tropical waters on the planet, seals are also known to vocalize: a captive male harbor seal named Hoover was taught to vocalize English with a prominent New England accent. Fast Facts: Seals and Sea Lions Scientific Name: Phocidae spp (seals), and Otariidae spp (fur seals and sea lions)  Common Name(s): Seals, fur seals, sea lionsBasic Animal Group: MammalSize: Range from 4–13 feet longWeight: Range between 85–4,000 poundsLifespan: 30 yearsDiet:  CarnivoreHabitat: Polar, temperate, and tropical seasPopulation: Unknown, but in the hundreds of millionsConservation Status: Tropical seals and sea lions have suffered the most from human and climatic changes. Two species are threatened; seven are currently classed as endangered.   Description Seals and sea lions are highly evolved for swimming, including flippers, a streamlined fusiform (tapered at both ends) shape, thick insulation in the form of fur and/or subcutaneous layer of blubber, and increased visual acuity for foraging at extremely low light levels.   Seals and sea lions are in the order Carnivora and suborder Pinnipedia, along with walruses. Seals and fur seals are related to bears, descended from an otter-like terrestrial ancestor, and they all have a more or less aquatic lifestyle.   Toshi Miyamoto/Getty Images   Species Seals are divided into two families: the Phocidae, the earless or true seals (e.g., harbor or common seals), and the Otariidae, the eared seals (e.g., fur seals and sea lions). The pinnipeds include 34 species and 48 subspecies. The largest species is the southern elephant seal, which can grow up to about 13 feet in length and more than 2 tons in weight. The smallest species is the Galapagos fur seal, which grows to up to about 4 feet long and weighs about 85 pounds. The species have evolved to their environment, and the handful of those species which are listed as threatened or endangered are those who live in the tropics where human interference is possible. The arctic and subarctic species are mostly doing well. Two species, the Japanese sea lion (Zalophus japonicus) and Caribbean monk seal (Noemonachus tropicalis) have become extinct in recent times.   Habitat Seals are found from polar to tropical waters. The greatest diversity and abundance among seals and sea lions are found at temperate and polar latitudes. Only three phocid species- all of the monk seals- are tropical and they are all either highly endangered or, in two cases, extinct. The fur seals are also found in the tropics, but their absolute abundance is low.   The most abundant pinniped is the crabeater seal, which lives in the Antarctic pack ice; the ringed seal in the Arctic is also quite abundant, with numbers in the millions.  In the U.S., the most well-known (and watched) concentrations of seals are in California and New England. Diet The diet of seals is varied depending on the species, but most eat primarily fish and squid. Seals find prey by detecting prey vibrations using their whiskers (vibrissae).   Seals and sea lions are mostly fish-eaters, although most of the species also eat squid, mollusks, crustaceans, marine worms, sea birds, and other seals. The ones that eat mostly fish specialize in oil-bearing species like eels, herrings, and anchovies because they swim in shoals and are easy to catch, and are good energy sources.   Crabeater seals feed almost entirely on Antarctic krill, while sea lions eat sea birds and Antarctic fur seals are fond of penguins. Image Source/Getty Images Behavior Seals can dive deeply and for extended periods (up to 2 hours for some species) because they have a higher concentration of hemoglobin in their blood and their large amounts of myoglobin in their muscles (both hemoglobin and myoglobin are oxygen-carrying compounds). When diving or swimming, they store oxygen in their blood and muscles and dive for longer periods than humans can. Like cetaceans, they conserve oxygen when diving by restricting blood flow to only vital organs and slowing their heart rates by about 50 percent to 80 percent. In particular, elephant seals exhibit tremendous stamina while diving for their food. Each elephant seal dive averages about 30 minutes in length, with only a couple of minutes between dives, and they have been seen maintaining that schedule for months on end. Elephant seals can dive up to 4,900 feet deep and stay down as long as two hours. One study of northern elephant seals showed that their heart rates dropped from a resting rate at the waters surface of 112 beats per minute, to 20–50 beats per minute when diving. Pinnipeds produce a variety of sounds, both in air and water. Many of the sounds are apparently individual recognition or reproductive displays, but some have been taught to learn human phrases. The most famous is a captive male harbor seal at the New England Aquarium named Hoover (1971–1985). Hoover was trained to produce a variety of phrases in English, such as Hey! Hey! Come over here! with a noticeable New England accent. Although little is known about sound production and acoustic communications as of yet, seals, sea lions, and walruses do have some voluntary control over their sound emissions, perhaps related to their ability to adapt to diving. In polar environments, seals restrict blood flow to their skin surface to keep from releasing internal body heat to the ice and freezing water. In warm environments, the reverse is true. Blood is sent toward the extremities, allowing heat to release into the environment and letting the seal cool its internal temperature. Reproduction and Offspring Because of their highly developed insulating fur- polar seals and sea lions must regulate their body temperatures between 96.8–100.4 degrees Fahrenheit (36–38 Celsius) in frigid waters- they must give birth on land or ice and remain there until the pups have built up enough insulation to withstand the cold temperatures. In many cases, mother seals must be separated from their foraging grounds to take care of their offspring: if they can locate on ice, they can still feed and not abandon the pups, but on land, in groups called rookeries, they must limit their lactation periods so they can go without eating for a period of four or five days. Once the pups have been born, there is a postpartum estrus period, and most females are mated within a few days of the last birth. Mating takes place at the rookeries, and the males exercise extreme polygyny in these dense aggregations, with one male fertilizing many females. In most seals and sea lions, gestation lasts just under a year. It takes between three and six years for pups to reach sexual maturity; females produce only one pup a year, and only about 75 percent survive. Female seals and sea lions live between 20 and 40 years. John Borthwick/Getty Images  Ã‚   Threats Natural predators of seals include sharks, orcas (killer whale), and polar bears. Seals have long been commercially hunted for their pelts, meat, and blubber. The Caribbean monk seal was hunted to extinction, with the last record reported in 1952. Human threats to seals include pollution (e.g., oil spills, industrial pollutants, and competition for prey with humans). Conservation Status Today, all pinnipeds are protected by the Marine Mammal Protection Act (MMPA) in the U.S. and there are several species protected under the Endangered Species Act (e.g., Steller sea lion, Hawaiian monk seal.) Threatened species include the Guadalupe fur seal (Arctocephalus townsendi) and the Steller sea lion (Eumetopias jubatus, near threatened). Endangered species include the Galapagos sea lion (Zalophus wollebaeki), Australian sea lion (Neophoca cinerea), New Zealand sea lion (Phocarctos hookeri) Galapagos fur seal (Arctocephalus galapagoensis); Caspian Seal (Pusa caspica), Mediterranean monk seal (Monachus monachus), and Hawaiian monk seal (M. schauinslandi).

The genre of dystopian novel from We by Zamyatin to 1984 by Orwell Research Paper

The genre of dystopian novel from We by Zamyatin to 1984 by Orwell - Research Paper Example Therefore, Clute and Nicholl (p.361) defines dystopia as a fictional society or community, which is in some crucial way frightening or undesirable. Dystopias are most of the time characterized by dehumanization, environmental disasters, autocratic governments, and other traits associated with a catalystic decline in the society. We by Zamyatin and 1984 by Orwell can be categorized as dystopian stories because they are characterized with the following: backstory, hero, conflict, and climax. First, since back story is part of the fictional world, a back story is necessary of how this world came to be or how it evolved from our current world. Secondly, the hero/protagonist intuitively feels something is wrong within the society and sets out to alter it, such as D-503 in Zamyatin’s We and Winston Smith in George Orwell’s 1984 .Next, in the conflict, the protagonists meets and is sometimes assisted by a group of individuals who are also attempting to escape or destroy the dy stopia. Lastly, in the climax of dystopian literature like We by Zamyatin and 1984 by Orwell, the dystopia is often not brought down, thus the stories remain unresolved. The elements of dystopias differ from political, environmental and social issues. The dystopian societies as the one depicted in We by Zamyatin and 1984 by Orwell culminated in a wide series of sub-genres of fiction and were utilized to raise awareness of the real world issues in relation to environment, religion, society, politics, economics, technology, and psychology, if left unaddressed, led to a dystopia-like condition in the future. Currently, dystopias have taken the form of a multitude of speculations, for example, poverty, pollution, political repression, and societal collapse. We is a classic dystopian novel that was set in the 26th century. Its message of hope and warning is as timely as the end of the 20th century as it was in the beginning (Parrinder, p.18). Yevgeny Zamyatin was a marine engineer and a Russian writer wrote this novel in 1919-1921. The novel was written as a consequence of author’s personal experiences during his life in the Newcastle suburb of Jesmond, the Russian revolution of 1905, and 1917, as well as the during his work in the Tyne shipyards during the First World War (Thomas, 314). This book by Zamyatin is one which ended up influencing other dystopian authors such George Orwell and Aldous Huxley. Orwell’s 1948 is a futuristic piece of work that the novelist chose to turn inside out the last two numbers of the year he had authored it, 1948 into 1984 to depict issues that would be solved by that time. Zamyatin is hailed as the grandfather of satirical futuristic dystopia genre. He goes ahead and takes the totalitarian and confirmative concepts of modern industrial society to a very extreme conclusion, portraying a state that trusts in free will which is the source of unhappiness, and that the lives of the general public is controlled with the mat hematical precision founded on the system of industrial efficiency which was formulated by Fredrick Taylor (Clute and Nicholl, 85). An examination of myths and symbols show that Zamyatin’s work is easily comprehended as an internal drama of a conflicted modern man as compared to the external drama reality in a failed utopia. Furthermore, the city is laid out as a mandala which had many archeotypes and was subject to an archetypical conflict. The utilization of color and other forms of imagery depicts that Zamyatin advocated for the same subjectivist as had Kandinsky as well as other European Expressionist painters. Zamyatin’s We novel is considered to be the first dystopian novel, since it was influential in the formation of genre and important in any study of literature. Dystopian stories

Democracy and Citizinship Essay Example | Topics and Well Written Essays - 2500 words

Democracy and Citizinship - Essay Example They employed varied methodologies, analytical and theoretical approaches in order to provide a clear understanding of political culture across the state. They both revealed the way civic culture should be culturally recognized as a fundamental right and stepping-stone for gaining political, social and economic objectives. In order to make democracy work, engaging citizens in policy making process and recognizing their fundamental rights is requisite. Therefore, this essay compares and contrasts on the issue of civic culture and making democracy work from a theoretical, analytical and methodological perspective from assorted texts. Differences between Civic Culture and Making Democracy Work from a Theoretical, Analytical and Methodological Perspective Almond and Verba carried out comparative cross-national survey in five democratic nations including the United States, United Kingdom, Italy, Germany and Mexico in order to determine the quantified ideas and attitudes that compose civic culture. They employed a comparative fashion for testing individual attitudes as a complex way of understanding the civic culture and democratic system in the five democratic nations. ... 11). They also believe that it is through dissemination of cultural ideas that contribute a stable democracy. Therefore, they limited the research to individual attitudes and avoided the question about government. Almond and Verba employed interview research methodology and posed inquiries about the perception of the perception of individual about the democratic government in relation to citizens (Almond and Verba 1964, p.70). They alienated respondents into three political culture categories, which included the parochial culture, subject and participant culture in order to generate comparability atmosphere to understand democracy (Almond and Verba 1964, p.71). From these categories, they found out that the respondent in parochial culture did not have knowledge or interests in political activities. However, respondents were at least conscious, and they had little information about politics in the case of subject culture. They also understood that their lives were under the government policies. In the last participant aspects of political culture, the respondents in participant culture had fanatically developed political efficacy ideas and competencies as political actors (Lane 1964, p.2). The three categories of political cultural aspects can combine and create change in the political system because they are not jointly exclusive. The political cultures are different because each category differs and they can be further categorized into a number of cleavage members. This is what makes Almond and Verba believe that the combination between the political culture categories can result to a balanced political culture (Almond and Verba 1964, p. 32). Almond and Verba employ comparative methodology to explore the

Cebu Pacific Essay Example for Free

Cebu Pacific Essay A. Economic Forces Generating billions in revenues and creating hundreds of thousands of jobs. In recent years, the global aviation industry has been through many ups and downs. From skyrocketing fuel prices to pandemics to recent financial crisis, aviation industry has confronted a very rough weather in last ten years or so. Consolidation in mature markets, higher ticket prices, modernization of airports, policies to reduce emissions and tremendous growth prospects in emerging economies have been some of the trends during the decade. According to recent industry reports, the global aviation industry is on the path of recovery and future looks optimistic and would present ample opportunities for the stakeholders. The airline industry is inextricably tied to the overall economy – even minor recessions result in reduced demand and increased sensitivity to prices for leisure as well as business travellers. Changes in the economy have a big affect on the airline industry. The elasticity of demand, externalities, wage inequality, and monetary, fiscal, and federal policies all have an impact on this industry. The airline industry is constantly changing due to today’s market and today we will be looking at the reasons behind it. By successfully managing opportunity cost, and adapting to an ever changing economic environment, airline industries can have economic success.However, the well-being of the nation’s economy will have a direct impact on the level of success experienced in the airline industry. During economic shortfalls in the nation’s economy, travellers will have fewer resources available to travel for pleasure. Contributing to the negative economic influences in the airline industry, future and existing policies targeting the airline industry will continue to hinder the industry’s ability to recover losses in periods of economic hardships. The launch of low cost airlines in Philippines has provided a boost for the  industry. Airlines that have been part of this trend are Asian Spirit and Southeast Asian Air, offering affordable fares to local and even international destinations. The public seems to have embraced this, as the rate of flying passengers has increased. This increased not only accounts for new fliers but also regular flying passengers who were on a budget and now have a choice to choosing budget over luxury. There are quite a few negative externalities in the airline industry. Another thing that the economy is affecting the airline industry is the competing airlines. The bigger airlines can afford lower fares which make it hard for the smaller airlines to compete. Different airlines have plans to expand but will not be able to until the cost of fuel is under control. For the low fare carriers who allow advanced booking, they will need to work on a plan to avoid bankruptcy. This will make the airline industry continue to boost prices due to the fact that oil prices are expected to continue rising due to the supply. B. Political Forces In 1973, from the Letters of Instruction (151 and 151A) the airline industry in the Philippines was monopolized by Philippine Airlines (PAL). The monopoly lasted for more than twenty years until the Executive Order 19 in 1995 which liberalized the airline industry establishing the domestic and international civil aviation liberalization policy in the country. The E.O 219 stipulates the removal of restrictions on routes and flight frequencies, as well as government control on fares and charges. Following the liberalization, the industry attracted new entrants such as Cebu Pacific, Air Philippines, Grand Air, and Mindanao Express. Unfortunately, Grand Air and Mindanao Express were unsuccessful, and then SEAir and Asian Spirit come to birth. Today, airline industry in the Philippines is under the regulations of Department of Transportation and Communication (DOTC) under the civil aviation sector. The Civil Aviation sector is composed of the Manila International Airport Authority (MIAA), Mactan Cebu International Airport  Authority (MCIAA), Philippine Aerospace Development Corporation (PADC), Civil Aeronautics Board (CAB) and the Civil Aviation Authority of the Philippines (CAAP) (formerly known as ATO). The Department continuously upgrades and improves the international and domestic airport facilities to meet international standards and to provide better service to the commuters. On the other hand, our airline regulatory boards also recognize the International Civil Aviation Organization (ICAO). The ICAO has several regulations that the local boards are following. Last March 19, 2009, the ISO 9001:2000 Certificate for NAIA terminal 1 was awarded by Anglo Japanese American (AJA) Registrars, Inc. after passing the Phase 1 Audit of the Passenger Facilitation Processes. On May 21, 2009 MIAA was given the upgraded ISO 1991:2008 Certification making the Authority and the NAIA Terminal 1 one of the very few institutions in the country that have passed this upgraded level of certification. Today, airline industry in the Philippines is facing a big issue in international safety standard. Early this year, the European Union banned airlines from Angola and vowed to block carriers from Sudan and the Philippines from starting flights to the 27-country bloc. The European Transport Commissioner SiimKallas said that they cannot accept airlines fly into EU if they do not fully comply with international safety standards. The Philippine authorities and airlines mad efforts to resolve this issue but still Philippines would be banned from the EU precaution. C. Socio-Cultural Forces Obesity One controversy surrounds the issue of airline companies tightening their seat restrictions for obese passengers. Some companies have gone as far as to charge an overweight individual the cost of two seats because of their size. This has created a stir, as it brings up the question of discrimination. As indelicate as this issue is, airline companies contend that it simply costs more to fly those more portly passengers. According to Newsweek, â€Å"A study concluded that the 10 pounds Americans gained on average during the 1990s required an additional 350 million gallons of fuel a year.†Ã‚  So it would seem that this issue has less to do with discrimination and more to do with simple arithmetic. Security Airline companies have undergone a dramatic shift in the safety precautions they take, upping the ante in security measures due to recent terrorist attacks. And while the increase in security may, on some level, ease the mind of the pilots, passengers and their families, it also increases the anxiety and frustration with the amount of time and effort it takes to get from the airport ticket counter to the terminal gate. Because of the few successful breaches in security that have occurred over the past decade, airlines will never again have the luxury of being so lax in terms of their security. Ethnicity Perception is a major factor in how we view the world. It is also one of the oldest studies in psychology. How we perceive ethnicity, as it relates to air travel, has much to do with September 11, 2001. Since then the eyes of the world have grown increasingly sensitive to the ethnicity of passengers travelling on airplanes. It has created something of a negative perception for particular races and religions. Bloomberg Business week reports, â€Å"Airline experts and executives say it’s important not to exaggerate the effects of terrorism fears.† However, because airline companies have had to exercise increased security measures because of terrorism, and because passengers have grown increasingly aware of possible threats, those perceptions are not easily dismissed. D. Technological Forces Internet as a way to book flights, check in, and check flight status – Before, ticketing offices were often jam-packed by people who wants to book flights, and most of the time, they are becoming irritated of the situation. Now, with the dawn of the Internet and Cebu Pacific Air’s entry to the world wide web, customers can now book flights without going to a ticketing office, pay their billings securely using Credit/Debit card, they can even change their flight details without bothering to go personally to CEB office, and check flight status that will be a much-used during storm  seasons and other obstacles that might hinder the the flight. Always new and improved software for airlines Acquiring and continuously upgrading its software is a very big positive impact for the company. It is a way of telling your customers and prospective customers that your airline will not cause them any hassles and troubles in the near future. Aside from having it as an impression of promising greatness, generally, all will follow to the good lead. New technology for airline employees Airline employees should be introduced with new technologies to avoid having problems in the future. The airline had purchased new equipments, machines to shorten the queue, but if they have no idea of how it operates, you will not obtain your objective. So every employee must be knowledgeable of technologies for we are now in the 21st century. New pilot training courses Finishing a course to become a pilot is not enough. Even if you have become one of the airline’s pilot, you still have to go through series of training courses and seminars to keep on track. Learning does not stop. Therefore as Cebu Pacific Air’s vow to excellence and safety, they are launching several training courses to avoid a doubt, if there is, for a customer to think whether the pilot is competent enough. By this, passengers can seat safe and sound. New security technology Website hacking is like an infectious virus that was troubling many people nowadays. But with the new security technology, customers will not have any bad thinking about paying securely using their Credit/Debit card. Cebu Pacific Air’s paying system was verified by Visa, MasterCard and VeriSign. It is a big sign that the airline has a very strong security technology that no hackers can destroy. E. Environmental Forces Contrails short for â€Å"condensation trails† or vapour trails are artificial clouds that are the visible trails of condensed water vapour made by the  exhaust of aircraft engines. As the hot exhaust gases cool in the surrounding air they may precipitate a cloud of microscopic water droplets. If the air is cold enough, this trail will comprise tiny ice crystals. The wingtip vortices which trail from the wingtips and wing flaps of aircraft are sometimes partly visible due to condensation in the cores of the vortices. Each vortex is a mass of spinning air and the air pressure at the centre of the vortex is very low. These wingtip vortices are not the same as contrails. Depending on atmospheric conditions, contrails may be visible for only a few seconds or minutes, or may persist for many hours which may affect climate. The main by-products of hydrocarbon fuel combustion are carbon dioxide and water vapour. At high altitudes this water vapour emerges into a cold environment, and the local increase in water vapour can push the water content of the air past saturation point. The vapour then condenses into tiny water droplets and/or deposits into ice. These millions of tiny water droplets and/or ice crystals form the vapour trail or contrails. The vapour’s need to condense accounts for the contrail forming some way behind the aircraft’s engines. At high altitudes, super cooled water vapor requires a trigger to encourage deposition or condensation. The exhaust particles in the aircraft’s exhaust act as this trigger, causing the trapped vapour to rapidly turn to ice crystals. Exhaust vapour trails or contrails usually occur above 8000 metres (26,000 feet) and only if the temperature there is below −40  °C (−40  °F). Engine Emissions Over the years, increasing attention has been paid to the sustainable development of the aviation sector. It is now widely recognised that the costs of these externalities must be internalised and paid for by the aviation industry and its users. Of all the externalities generated from commercial flights, aircraft engine emissions have extensive impacts on human health, vegetation, materials, ecosystem and the climate. Currently, only around 10 airports have applied engine emissions surcharges, which are in Switzerland, Sweden and the United Kingdom. However, the impacts of aircraft engine emissions are a world-wide issue and have drawn significant attention in the global community. This research aims to evaluate the impacts of aircraft engine emissions  charges, based on the estimation of social costs, on airlines operating costs. The paper firstly presents the methods of assessing the social costs of aircraft engine emissions. The environmental impacts of aircraft engine emissions include both aircraft landing and take-off and the cruise stage. The social costs of aircraft emissions vary by engine type and aircraft category, depending on the damages caused by different engine pollutants on the human health, vegetation, materials, aquatic ecosystem and climate. Nine Asian airlines, covering both network full service carriers and low cost airlines, are selected for empirical analysis. The implications of aircraft engine emissions charges on the selected airlines and the corresponding effects on operating costs were measured, involving five existing intra-Asian flight routes. It was found that the aircraft engine emission charges would range from 3-12% of the airlines ¡Ã‚ ¦ operating costs, depending on the route distance, aircraft types and the nature of airline operating characteristics. Airport noise Aircraft noise is noise pollution produced by any aircraft or its components, during various phases of a flight: on the ground while parked such as auxiliary power units, while taxiing, on run-up from propeller and jet exhaust, during takeoff, underneath and lateral to departure and arrival paths, over-flying while en route, or during landing.Aerodynamic noise arises from the airflow around the aircraft fuselage and control surfaces. This type of noise increases with aircraft speed and also at low altitudes due to the density of the air. Jet-powered aircraft create intense noise from aerodynamics. Low-flying, high-speed military aircraft produce especially loud aerodynamic noise. The shape of the nose, windshield or canopy of an aircraft affects the sound produced. Much of the noise of a propeller aircraft is of aerodynamic origin due to the flow of air around the blades. The helicopter main and tail rotors also give rise to aerodynamic noise. This type of aerodynamic noise is mostly low frequency determined by the rotor speed. Much of the noise in propeller aircraft comes equally from the propellers and aerodynamics. Helicopter noise is aerodynamically induced noise from the main and tail rotors and mechanically induced noise from the main gearbox and various  transmission chains. The mechanical sources produce narrow band high intensity peaks relating to the rotational speed and movement of the moving parts. In computer modelling terms noise from a moving aircraft can be treated as a line source. Aircraft Gas Turbine engines (Jet Engines) are responsible for much of the aircraft noise during takeoff and climb. However, with advances in noise reduction technologies the airframe is typically noisier during landing. The majority of engine noise is due to Jet Noise although high bypass-ratio turbofans do have considerable Fan Noise. The high velocity jet leaving the back of the engine has inherent shear layer instability (if not thick enough) and rolls up into ring vortices. This of course later breaks down into turbulence. The SPL associated with engine noise is proportional to the jet speed (to a high power) therefore; even modest reductions in exhaust velocity will see a large reduction in Jet Noise.

The Father of Western Philosophy Socrates Essay -- essays research pap

The Father of Western Philosophy: Socrates Since the dawn of man, the invariable love of knowledge has kindled the hearts of humankind. That true passion in the heart for mankind over the flux of time is the study of philosophy. One of the greatest embellishments to philosophy overtime is the lionized Socrates of Athens born in 469B.C. His life exemplifies a true philosopher’s life, and the aspect of wonder that has cloaked mankind since the beginning of time. Therefore, the philosophical significance of Socrates is strenuous to parallel for he: practiced systematic and logical reasoning, lived an undemanding life, and pursued truth and wisdom. At first, the heart of philosophy lies in practicing systematic and logical reasoning which Socrates indeed was loquacious with. A philosopher has to pay great attention on how to go about reasoning with someone which characterizes a fine philosopher. Indeed, Socrates is able to accomplish that quite admirably: †¦Socrates is doing the kind of critical questioning that characterizes philosophy. With careful, logical reasoning and in a...

The Return of Martin Guerre

The purpose of this paper is to introduce, discuss, and analyze the book â€Å"The Return of Martin Guerre† by Natalie Zamon Davis. Specifically, it will discuss the life of the peasant during the Middle Ages. This book is a fascinating account of a true case that happened during the 16th century in France. The book is also an excellent example of how the peasants lived in the Middle Ages, from what they ate, to how they traveled and what their family lives were like. This book shows that life in the Middle Ages was difficult and demanding, but it seems a little bit peaceful and serene, too. The main occupations were farming and raising sheep or goats, and there were tradesman in the villages who worked for a living, such as a shoemaker, a blacksmith, and such. Martin Guerre and his family were tile makers, but they also farmed and raised sheep to become relatively prosperous in their small village (Davis 14). The peasants were uneducated, (the Guerre's town did not even have a schoolmaster), and most could not read, and could only write a small amount (Davis 15). They also married their children off very young, and often made matches for them. Martin Guerre married when he was only fourteen, and his wife was even younger (Davis 16). Life revolved around the village, the church, and the family, and it was a very busy but seemingly contented lifestyle. Their main concerns were the family and simple survival. Everything they did was to feed and clothe the family, from raising grains and grapes to raising sheep so they could spin the wool into cloth and clothe the family members. When they became more successful, it was to make money and rise up in stature in the village community, but peasants who did not have trades worked the land for their own survival. They were also extremely close-knit families, often living nearby each other, so family was important for them, as well. They worked together as a family, and widows lived with one of the grown sons, creating an extended family unit. Family relationships were important in this society, and they were the source of land and dowries for the children, which were very important at the time. In the Basque country, families often lived together, as the author notes, â€Å"When a household is set up with two generations of married folk, it is not the Basque combination of the old heir and the young heir, but a widowed parent, usually the mother, with one of her married children† (Davis 11). Even when Martin's uncle married, he moved nearby to another house, and lived close to his relatives. Martin returned with his bride to his father's house after they married, and lived with his family under one roof (Davis 18). Since their main concern was survival and perpetuation of the family, this indicates how important family life was to the peasants. Women had a lesser position than men did in the society. Davis writes, â€Å"At the parish mass, she would have to get used to the fact that her women did not push ahead of the men to make their offerings, did not go about the church to collect for the vestry, and din not serve as sacristans† (Davis 15). Women were also blamed for a man's impotence, as Davis notes. She writes, â€Å"In the sixteenth century, it was usually blamed on the power of a woman outside the marriage† (Davis 21). The fact that Martin abandoned his wife and newborn son after eight years of marriage shows what low status women had in society. She had no recourse, she lived in a foreign household, and she could not even remarry. Girls were not educated; instead, they learned â€Å"women's work† like spinning and cooking, and they were always at the mercy of their husbands. Davis writes, â€Å"First a world where organizational structure and public identity were associated exclusively with males† (Davis 29). The women worked in the fields, helped raise the livestock, served as midwives, cooked and baked. They were essential to everyday life in the peasant world, but they held no rights or privileges. The only women that really rose up in society were the widows, who could earn the respect of others and wield â€Å"informal power† (Davis 31). Armand Du Tilh was able to get away with his deception for several reasons. First, he resembled Guerre enough that people mistook him for the missing man (Davis 39). Next, he learned all he could about the missing man so that he could fool Martin's family into believing he was actually Guerre. Davis writes, â€Å"He informed himself as cunningly as he could about Martin Guerre, his situation, his family, and the things he used to say and do† (Davis 39). He also grew a beard to hide any differences in his face, and took great pains to learn the villagers' names and how he interacted with them when he had lived in the village before. In short, he learned every detail about Martin Guerre's life, and convinced people he was Martin because of all the details he seemed to â€Å"recall† about his prior life. Davis believes that he was accepted because people wanted him to come back for all those years, and that he came â€Å"announced† as Martin Guerre, and so people wanted to believe it was true (Davis 43). Most of all, Bertrande's acceptance of the new Martin helped soothe the minds of others. It is easy to see why Bertrande would accept the imposter. Davis writes, â€Å"What Bertrande had with the new Martin was her dream come true, a man she could live in peace and friendship (to cite sixteenth-century values) and in passion† (Davis 44). They also seemed to have become very attached to each other in their new life together. In conclusion, this book is a fascinating story of deception and betrayal, but it is a fascinating glimpse into the everyday life of the sixteenth-century peasant, as well. The book shows how families lived, survived, and even thrived, how women were treated in society, how important the Church was to so many aspects of life, and how difficult life was for many peasants. It is a good book to read to learn the more intimate details of life in the Middle Ages. The Return of Martin Guerre The film The Return of Martin Guerre is based on a true story about a young man, Martin Guerre, during the mid-16th century. It takes place in a small peasant town, Artigat, located in southwestern France. Martin is married off at a young age but is unhappy with his life. He decides to abandon his family and join the army. After several years gone, he finally returns to the village. The village is ecstatic of his return, especially his wife Bertrande. However after a disagreement with his uncle over land, the village begins to question whether his is truly Martin Guerre. Their skepticism proves to be accurate when finally the real Martin Guerre returns. The fake Martin, known as â€Å"Pansette† is then executed for his crime. This film illustrates the concerns and lives of the people in 16th century France, through the interplay of social, religious and political institutions. In the film, we see marriage being treated as a social matter, rather than a religious matter. During the 16th century, marriage began to be treated as secular, instead of a sacrament. Because of this parents’ control over whom their children married began to increase (Western Civilizations, 357). At a young age, Martin’s family married him off to Bertrande de Rols. Bertrande belonged to a well-off peasant family. Bertrande was chosen by Martin’s family based on what her family could offer to Martin. Her dowry included a bed, linen sheets, wool and a vineyard, among other items of value. Because marriage involved the inheritance of property, most believed it was too important of a matter to be left in the hands of the children (357). Once Martin’s father passed, Martin would inherit his family’s land. During the 16th century was the father’s role to instruct and discipline his household, while the woman was to tend to and show obedience to her husband, and also to bear children (Western Civilizations, 357). After the marriage, Bertrande moved in with Martin and his family. Martin worked underneath his father and learned from him. However soon into the marriage, it was discovered that Martin could not consummate his marriage and therefore the family did not have children. In the film, we see how infertility was dealt with socially and religiously during this time. The village poked fun at Martin’s infertility during a festival. During the 16th century, festivals served a social function. Usually they were used for celebration and demonstration of solidarity. However, like in this case, festivals were used as competition between classes and were incredibly violent (Wahl, â€Å"Festivals† notes). During a Candlemas festival, a â€Å"symbolic castration† took place. Martin was dressed up as a bear. The villagers pretended to hunt him and cut off what symbolized his genitals. Bertrande claimed that he had been put under a spell and a Catholic exorcism is performed. Both Martin and Bertrande are tied to a post naked, while the Priest performs rituals. After this, Bertrande becomes pregnant with their son, Sanxi. Though his infertility was reversed and his son was born, Martin was unhappy with his life. He did not like farming and kept to himself. After an argument with his father over stolen grain, Martin leaves during the night and does not return for several years. During this time, Martin’s father passes. In the 16th century, when a father dies the estate is given to the eldest son. In this case, it was Martin. However, because Martin is not around, Martin’s uncle takes control of the Guerre’s estate. In order to keep the estate within both families, Bertrande’s mother marries Martin’s uncle. Throughout Martin’s absence, Bertrande remains married to him. Because there was no proof that Martin was dead, Bertrande was not considered a widow and therefore could not remarry. It was also not common for the Catholic Church to annul a marriage, unless it could be proven that either party had not freely consented to the marriage (Western Civilizations, 357). During the 16th century, a person’s identity was based on his or her actions rather than appearance. For this reason, the fake Martin Guerre, Pansette, was able to convince the village that he was the real Martin. No formal records or pictures were kept of people at this time. The people of the village relied on the memory of Martin. With Pansette’s slight resemblance to Martin and his vast knowledge of Martin’s life, he was able to fool everyone. Pansette tells stories of the places he visited. Specifically he spoke of the men he saw from Brazil. He describes the men as naked and in chains with feathers on their heads. Pansette tells them that they eat their prisoners’ hearts, and share their land and women. He also told them that women make the decisions and go to war for the men. Bertrande seems shocked by this and asks if they are human or if they have souls. This is significant because it demonstrates the power of men at this time. In the 16th century, men made the decisions, while woman were expected to obey their husbands. Therefore it was strange for them to hear of woman having power over the men. After a dispute over the land between the fake Martin and his uncle, his uncle begins to question whether he is the real Martin. Rumors go around about this and the village is split on this issue. With this issue, we see how it is dealt with through religion and politics. The Toulouse Parliament of France is put in charge of this matter and questions Bertrande. She stands by Pansette, claiming he is the true Martin Guerre, although she knows that he is not. From a religious point of view, by doing this she is living in mortal sin and damning her soul and politically, she can be hanged for this crime. This case is brought before a court. Those who testified claimed that Pansette was not an imposter, until a man walks in claiming to be the real Martin Guerre. Martin’s family, including Bertrande, admits that this man is, in fact, the real Martin. Pansette finally confesses that he is not Martin and learned everything he knew about him through Martin himself. Although Pansette is found guilty, the court frees Bertrande from prosecution as a collaborator. This is because the court holds the real Martin Guerre to be partially responsible for not acting as a true husband. This issue is considered so serious because it is an issue of property. By pretending to be another man, Pansette is taking another man’s wife and stealing his wealth. During the 16th century, crimes against property, such as theft and arson, were punishable by execution (Wahl, â€Å"Counter Reformation† Lecture). The story of Martin Guerre and his return demonstrate the concerns and lives of people in 16th century France, through social, religious and political institutions. Socially, we see the act of marriage as a secular matter, ather than a religious one, where wht dowry a woman can offer determines if she is fit to be a wife. Also, we see the issue of identity and individuality based upon knowledge and actions, rather than appearance. It can be argued that during this time people know each other better than today. To decide if Pansette was the real Martin, they based their decision around how he acted and what he remembered about life before he left (although Mart in’s family was fooled by the fake Martin), while today identity is based a lot more on just appearance. We see how religion plays a role in their actions. They believed to fix Martin’s problem of infertility, they must perform an exorcism to get the demon out of him. Also, we see how by believing the fake Martin, Bertrande is living in sin under God. Finally, politically we see just how serious Pansette’s crime was. By interfering with the real Martin’s property (his family and land), he is committing the ultimate crime and is executed for this.

T box

The T- box is a power generated device that harnesses wind energy as trains run over railroad tracks. This alternative form of wind energy produced by trains is very unique, as it does not depend on any natural energy sources. Instead, the energy generated from this device is produced as a consequence of human activity. The T- box device generates energy without any interference of the normal train operation – the device is installed between railroad ties, and is partially buried underground. As the train passes over the device, the wind generated from the train spins the turbine nside the T- box to generate electricity.The T- box contains all the mechanical components required for harnessing, storing and supplying converted power. Hence, the power generated from this device can be supplied to public facilities along the railway and also to remote areas where electricity has not yet reached. The T-box How much power can the T- Box generate? A train moving at 125mph would gener ate a wind speed equivalent to 50 feet/ second. Wind blowing with such speed will let a normal wind power generator harness about 3500W of power. If a train is about 656 feet long, running at the pace of 187mph, and it moves along a 0. 2 mile railway track in about 18 seconds, the power generated in this small period by the T- boxes laid on the tracks will be 2. 6KW. Qian and Luparini estimate that about 1 50 T-box devices could be accomodated along a 0. 62 mile railway track. Installation of the T- box To fit the T- box on the tracks, some work has to be done on them: Firstly, concaves have to be constructed in cement between each of two sleepers Two brackets then ave to be placed on two sides of the concaves The brackets have to be examined to ensure that they are well fixed The T-box is then set upon the maneuvered tracks Installed T- boxes Is the T-box eco friendly?The T- box has so far been considered quite environmentally friendly. The T- box does not produce any harmful chemi cals nor has it been proven to have any other side effects thus far. Anticipated problems Keeping the T- box devices clean can pose great problem. As the train passes, quite a bit of dirt and debris will be kicked up, and will land on the upper surface of the T- ox. Also, grease and grime deposits escaping from underneath will contribute to contaminating the device.Future of the T- box As the hunger tor alternative torms ot energy continues, the T-box nas generated hope. This device presents a new generation of wind power generators, and has created quite a sensation among techno buffs. However, it is important to remember that the design is still in the conceptual stage and has not taken into account all of the preservation and maintenance issues that are likely to pose a problem in any future use of this device.

School Violence Essay example

School Violence Essay example School Violence Essay example School Violence (Bullying) School violence has gone on for as long as schools have been open. Psychologists categorize the different types of school violence into three separate categories; verbal,physical, and retaliation. They say Verbal is the most impacting type of school bullying cause it stays with you longer and has more psychological effects on the victim. While physical shows signs,retribution is mainly a backlash of students excluding and ignoring the victim. It has become a society problem, although sometimes its not acknowledged we all know its there. It usually takes something massive to bring everyone’s attention to the problem, such as Columbine shooting. There are several instances that are not as publicized as the Columbine but they still impact the community. Such as the mother arrested for chocking her daughters bullier, or the young girl that hung herself, and even the coach that joined in on the bullying of a student. Bullying takes place more than just in school, its cyber as well and harder to stop. There was an instance in Florida where the mother of a teen girl was concerned when her daughter was slipping into depression and having suicidal thoughts because of a cyber-bully. Since the systems have not caught up to the cyber world most cases are hard to get a result from reporting it. The daughter took the steps to stop this by informing the schools resource center and the police of the incidents going on, yet they did nothing to help. With the mom concerned for her daughter she ended up loosing it when she saw her daughters tormentor in the mall. She ended up chocking the teenager and landing in jail. Her daughter was under verbal bullying, which is the highest form and longest lasting of the three bullying categories. The mother taking things into her own hands, in my opinion, wasn’t the best thing to do, but sometimes you get to where you have limited options and the primal side comes out. Most people think school violence is focused on certain types of people, such as the poor, younger and social misfits. Even though most the stories you hear are generally about the kid that wore black and stayed in the corner type, its not always true. Even the popular pretty people can be a victim as well. Such as in the case of the teenage girl that hung herself. She was a beautiful girl in the popular crowd that was described as having a lot of friends and being well liked by all. But she became the main target for other girls out lashings. They would bully her about being to pretty and to popular, they started degrading her bringing her down to the lowest levels they could get her to. She finally broke and committed suicide by hanging herself in her room, she didn’t die a slow death she died six days later while on life support. When they canvased the school for information a lot of students informed the parents and officials that in the recent proceeding months she has b een the victim of harsh bullying, including verbal, physical and retaliation bullying. Since no one truly know the reason for the targeting of this young girl, it makes it harder to find how to stop this vicious cycle. Physiologists do believe it is an learned action to bully people. Another misconception of school violence is that it is only carried out by the students, this too is not the case. Anyone can be the tormentor or the victim, such as the case of the gym teacher that joined in on the physical bullying of a teenage student. Since violence is all around a very horrible thing it doesn’t help when the teacher is implementing or encouraging it. That is what happened in a Washington school, the teacher and rest of the class were physically hurting another student during study time. They were pinning him down writing on him, putting cones on his head and stuffing socks in his mouth to muffle the screams while they were swinging him by his limbs around the room. Some students thinking it was so cool to do video taped

Sugar of Lead

Sugar of Lead One way you might suspect lead is seeping from your plumbing into your water is if the first water from the tap tastes sweeter than water after the tap has run a while. Lead tastes sweet. In fact, lead (II) acetate [Pb(C2H3O2)2Â ·3H2O] is a compound that has another name: sugar of lead. Sugar of lead has been used as a sweetener throughout history. No honey or sugar? No problem! There is a calorie-free alternative. Its toxic, but you wont put on pounds from eating it. If you use enough of it, you might forget to eat altogether. The perfect diet aid.The ancient Romans would boil down grape juice in lead pots and use the resulting syrup to sweeten wine and preserve fruit. We all know how it went down for the Romans, but lead acetate is still in use today. The modern preparation of lead(II) acetate is made by mixing aqueous acetic acid with lead carbonate and evaporating off the water. Have you noticed some lipsticks taste sweet on your lips even though when you read the ingredient list, they contain no sugar or other sweeteners... well... except the lead acetate. Lead acetate is found in red lipsticks more than other colors. The chemical helps with colorfastness, which is why its also using in dyeing, including progressive hair color, like Grecian Formulaâ„ ¢ for men. You can have a head of youthfully dark hair, all the better to attract that lovely lady with the ruby red lips and the sweet, sweet kiss.Crystal Photo Gallery | What Makes Lead Poisonous?

IT and Entrepreneurship - Essay Example This can be used by working groups for efficiency in project management and also assists by enhancing productivity. Online forums can be made for the purpose of discussing key issues among employees of a company. In large organizations, intranets normally get managed by the IT or Human resource departments. An intranet website performs and appears just as any other website, the exception being that it has firewall behind it to differentiate authorized and unauthorized users. An intranet is a very helpful private or personal network, which naturally is not necessary in all organizations. Therefore, the management of a company should decide whether or not to implement an intranet. Although the benefits of this technology are evidently clear, it is not compulsory to have it in the organizational system. The architecture behind intranet can be conceptualized as integration of four major elements: corporate information services, intranet users, communication links and the web server. This paper is going to discuss in length problems related to the use of intranet with relation to learning and inspiration. It also tries to give suggestions on the various features organizations can build on their intranet (Phan 2002, p.26). All network concepts have disadvantages; by nature, risks associated with security come first. This does not only concern issues to do with software security but also how employees handle and manage their passwords and usernames. In some instances, passwords can be left on places where everybody can be able to see while other users tend to choose simpler passwords that can be easy to guess. Most companies are not well to do with this method or way of information and data sharing. While one of the major purposes of intranet can be to enhance file sharing and communication in an organization, some employees might be frustrated since they might not be comfortable with the technology. The use of intranet technology also changes the work culture of an o rganization. Executives mostly in the top level management will get into the habit of delegating the duty of handling information and mails. The practice of sharing passwords and other vital company information could be fatal and so it could be necessary to respond to security threat posed by this. Another major setback brought about by the use of intranet is the level of reduced face to face interaction by employees. As the human interface gets reduced, the lack of bonding between parties can lead to loyalty issues and stamp down learning rapidly. This poses a great danger as it leads to impersonalization of the business. The complexity of the network system to employees also can inhibit learning and inspiration. Employees can view it to be very difficult to understand and use and so, not use it to its maximization. The network system can make employees feel overburdened by the amount of information and data it contains (Phan 2002, p.27). There are numerous features that could be a dded to an intranet network to aid learning and inspiration to users. Some of them include: Personalization and Segmentation: Bad user adoption can be mentioned as the major reason why intranet network projects fail. User experience can be an increase by tailoring content to meet user needs and also communicating in a more personal way. For increased user interface, a company should personalize content according to
