Electromagnetic - Research Paper Example It is sometimes used to bar radio frequency electro magnetic rays as well. This method is known as RF Shielding. Depending on the material and its physical properties such as size, shape, thickness, and the frequency of electromagnetic fields and even the orientation of the material vis-Ã  -vis magnetic field, the effects of magnetic shielding can be reduced or increased. We must note that magnetic fields are only redirected using these materials and not created or destroyed. This is because magnetic field lines are attracted into the material and kept from spreading out as they take the path offering the least resistance (Appleman and Dailey, 1974). The reason for this stems from Maxwell’s equation; Using one magnet, each of the three materials was brought closer to it. The idea was to see which ones are attracted and which ones are not. The former being classified as magnetic and the latter as non magnetic. Firstly, one of the neodymium magnets was brought closer to the other which was attached to the thread. The magnet visibly moved towards the other magnet and thus it was established that a magnetic field exists. Then the only non-magnetic conductor here i.e. Aluminium was placed between the two and then the neodymium magnet was brought towards the other. It was interesting to note that although the magnet on the thread did not come comparatively closer to the aluminium, it does exhibited an interesting phenomenon; as the magnet on the other side of aluminium was moved, so did the magnet on the thread. This means that although aluminum is non-magnetic, it does interact with magnets in other ways. Procedure and observations:The magnet was brought closer to the copper pipe. No force was experienced and both the magnet and copper offered no attraction. Thus, copper is deemed as non-magnetic. However, it cannot be used for magnetic shielding since the effects of magnet were seen on the other side of the copper as

Indian Gaming Regulatory Act Essay Example for Free

Indian Gaming Regulatory Act Essay In 1988, Congress passed the Indian Gaming Regulatory Act establishing gaming on Indian reservations as a means of helping tribes become self-sufficient and less dependent on government dole-outs. Donald Bartlett and James B. Steele co-wrote an article which appeared in Time magazine on December 16, 2002 entitled â€Å"Wheel of Misfortune† negatively criticizing the consequences of instituting the said Act. A day later, the Native American Times published an editorial which contains dissenting arguments against the first article. According to Bartlett and Steele, the major defect of the Act is the unequal redistribution of profits derived from gaming in the reserves: â€Å"It gives billions of dollars to the white backers of Indian businesses and nothing to hundred of Native Americans living in poverty†¦hundreds of millions of dollars to one Indian tribe with a few dozen numbers—and not a penny to a tribe with hundreds of thousands of members†¦(78)† The bulk of the essay expounds and provides evidence to these assertions. It also points to the fact that while these tribes earn tax-free revenues, they continue to collect millions in government aid. The Native American Times editorial, meanwhile, accuses the Time magazine article as simply a piece that â€Å"fan the flames of racism with lies (â€Å"Indian Gaming† 84)† and proceeds to either refute or justify the points raised of the latter. Bartlett and Steele claim that only a few Indians are benefiting financially from the Native-American gaming industry thus defeating the purpose of the act, which is to raise the average Native American out of poverty. At the same time, a high percentage of the profits from these lucrative casinos go to the wealthy leaders of tribes. The editorial counters this argument by stating that there are varied reasons why some tribes do well than others. It cites the case of Oklahoma, home to more Native Americans than any other state. The state prohibits Class III gambling thus preventing an opportunity for the Native Americans in Oklahoma from realizing the Congressional Act. Today tribes continue to â€Å"fight with every resource available to them to hold off those who would send them back to the metaphoric reservation (â€Å"Indian Gaming 85). † The editorial also praises the success story of the Shakopee tribe which the Time magazine article derides. The success is well-deserved, according to the editorial, since this group has experienced one of the most harrowing histories of violence inflicted against Native Americans. For all its passionate defense and criticism of the Time magazine article, the editorial of the Native American Times does not touch on the other issues raised by the former like cronyism among the tribal leaders, the involvement of white Americans behind the casino operations, and the applications for recognition by extinct tribes that suddenly resurrects because of the business opportunity. Then again, the former is a lengthier and more detailed presentation complete with figures and facts, in keeping also with its being an investigative article. Nevertheless, it can be argued that the editorial does not need to refute the Time magazine article point by point and that its entire argument is summed up when the editorial writer states that the reason why people like Bartlett and Steele are being too critical about the Indian Gaming Regulatory Act is because â€Å"the thought of rich Indians is against nature we can only assume (85). Inequality, anomalies, and other issues about the Native American and their casinos may exist but they are no different to those in regular gaming industries. Despite some wealthy members, Native Americans are still the poorest and most victimized people in America.

Besires Theory is Fully Consistant with the Humean View Essay -- Ethic

Abstract One Humean view holds that motivation requires beliefs and desires, which are separate and distinct mental states. Beliefs are disposed to fit the world, and desires are disposed to make the world fit them. This view is thought to eliminate besire theory, according to which moral judgments have both a world-mind direction of fit by representing the ethical facts of the matter, and a mind-world direction of fit by motivating action accordingly. Here I argue that besires are fully consistent with the Humean view. The Humean view should be cast at the level of types, while besire theory is supported by introspection on psychological tokens. Existent Humean arguments against besires do not go through, and besire theory remains a viable option—indeed, the option best supported by the evidence—without rejecting the Humean view. 1 A Case for Besires According to the Humean view of motivation, beliefs alone cannot motivate. According besire theory,1 some first person moral judgments (judgments of the form ‘I morally ought to ÃŽ ¦Ã¢â‚¬â„¢) are both belief-like and desire-like in that they represent things as they morally are, and motivate appropriate actions. For example, on besire theory my judgment ‘I ought to visit my grandmother in the hospital’ can both represent a factual moral obligation and motivate me to visit my grandmother without the help of some separate desire-type psychological state. Can besire theory be right? Not under the Humean view, for on that view besire theory mistakenly attributes motivationally hot, desire-like properties to a certain class of beliefs. It would seem that our options are highly constrained: either we embrace the Humean view, and characterize first person moral judgments as belie... ...o necessary connections between distinct mental state tokens, simpliciter internalism entails besire theory. 12 Shafer-Landau argues for a similar position, though he calls some beliefs â€Å"intrinsically† motivating. Shafer-Landau 2004, 147-48. 13 Only when we combine besire theory with an essentialist claim, for example, that no state counts as a besire unless it actually motivates, do we get the result that moral judgments necessarily motivate. This essentialist claim is too strong for any desire-type state, for even occurent, normal desires combined with relevant means-related beliefs can fail to realize their functional role. 14 One might think that the standard cognitive view of moral judgments evades the burden of showing how moral motivation fails, but thereby gains the burden of explaining the reliable connection between moral judgments and motivation.

Knights :: essays research papers

Knights   Ã‚  Ã‚  Ã‚  Ã‚  In the fourth century A.D. the Roman Empire fell and Europe was invaded by various barbarian tribes. One of the dominant groups was the Franks of central and western Europe, who gradually expanded their power until their leader Charlemagne became emperor of the West. Powerful local lords and their mounted warriors offered protection to peasants, who became their serfs in return. By the 11the century a new social order was formed my armored knights, who served a local lord, count, or duke, and were in turn served by serfs. When males were about seven, a boy of noble birth who was going to become a knight was usually sent away to a nobleman’s household, often that of his uncle or great lord, to be a page. Here he learned how to behave and how to ride. About 14, he was apprenticed to a knight whom he served as a squire. He was taught how to handle weapons and how to look after his master’s armor and horses. He even went into battle with his knight, help ing him put on his armor and assisting him if he was hurt or unhorsed. He learned how to shoot a bow and to carve meat for food. Successful squired were knighted when they were about 21 years old. Young men who wanted to be knights had to keep fit. So squires trained constantly to exercise their muscles, and improve their skills. They practiced with each other and also sometimes with their knightly masters.   Ã‚  Ã‚  Ã‚  Ã‚  The main body armor worn my early knights was made of mail, consisting of many small, liked iron rings. During the 12th century, knights started to wear more mail. Their sleeves got longer, and mail leggings became popular. A padded garment called an aketon was also worn below the mail to absorb blows. In the 14th century knights added steel plated to protect their limbs, and the body was often protected further with a coat-of-plates, made of pieces of iron riveted to a cloth covering. A suit weighed about 44-55 lbs. And the weight was spread over the body so that a fit man could run, lie down, or mount his horse unaided in his armor. The only problem was that the armor quickly made you hot. By the 15th century, knights were protecting themselves with full suits of plate armor. The armor’s smooth surface deflected the edges and points of weapons.

Fear in Lord of the Flies Essay

Human are the most civilized species on this planet. However, what makes people act civilly is constantly questioned. This question is explored in William Golding’s novel, The Lord of the Flies. In the novel, the fragile state of civilization created by the boys is constantly pitted against the destructive force of fear which motivates the boys to desert their civilized upbringing and hunt first and finally become murders. When the boys land onto the island, they know there are no adults or parents around so they know they have to create their own civilization. The boys attempt to create a civilization by each one having a job. Additionally, they elect a leader; establish rules and consequences, use the conch one person at a time, hunt, and keep the fire going in a case ship passes by. Their civilization is fragile because of the age of the boys and the lack of parental maturity. Shortly the boy’s civilization isn’t working because they know that they can get away with things that they can’t get away with at home. For example, â€Å"Here, invisible yet strong, was the taboo of the old life. Round the squatting child was the protection of parents and school and policemen and the law. Roger’s arm was conditioned by a civilization that knew nothing of him and was in ruins† (Golden 62). ————————————————- Despite the beauty of the Island, fear is all around them. The boys think that the â€Å"beast† is an animal on the island when it really is the beast within all of them. Simon finds out the beast is not an animal. The pig tells Simon that if he tells everyone that the pig is within all of them the pig is going to kill him. For example, â€Å"This is ridiculous. You know perfectly well you’ll only meet me down there-so don’t try to escape!† (Golden 143). ————————————————- ————————————————- ————————————————- ————————————————- ————————————————- ————————————————- ————————————————- Jack quickly takes the most brutal job for himself jis explains â€Å"All, the same you need Army-for hunting† (Golding#32). This civilization is fragile because of the age of these little boys and there is no parental control.

A Man Pushed to the Edge essays

A Man Pushed to the Edge essays I ask, is it possable for obsession, desperation, and tradgity to push a man over the edge of sanity to maddness? The film The Field, written/directed by Jim Shariden and produced by Noel Pierson, shows one man's obsession with his field causes many tradgic events to occur. McCabe, played by Richard Harrison, is obsessed over a field that has been in his family for years,that had been bought by an English lady from his father durring the potato famine. McCabe now rents that land from her to keep the land n the family. One of the main problems in the filmis that the widow decides to sell the farm by putting it up for aution. McCabe is fine with the autioning off of the land because he knows that no one in the village would take the chance and bid against him. A critic for the Desert Sun News remarks that "...the larger-than-life "Bull" McCabe, a bearish bully who has terrozied his tiny village-not to mention his family-for years"(Hicks). In other words "The Bull" McCabe has alot of pull in the village and no one dare to cross him. Though in McCabe's mind the land was already his, there was a quick reality check in store. An outsider, which they called The American, played by Tom Berringer, unknowingly bid against McCabe and The American was willing to double and bid that McCabe made. In some senses The American could be viewed as the villian in this story. His idea was to bring this small Irish villige into a nw age by cementing McCabe's field in a campain for Roads and Factories. I believe that the fact that The American is rather ignorant to the way of life of those in the village slightly sways him away from the villiness type, because he belived he was doing something good by helping the town progress. ...

Book review of Trust Us Were Experts by Sheldon Rampton and John Stauber.

Book review of Trust Us Were Experts by Sheldon Rampton and John Stauber. In an era of blatant disregard for journalistic objectivity, alleged vast right-wing conspiracies and the myriad books that attempt to enlighten the average citizen of the evils of corporate America, advertising, media bias and any form of sensible government, we have yet another boogey-man expos © by the editors of PR Watch: Trust Us We're Experts by Sheldon Rampton and John Stauber.In the true spirit of "The X Files" and yellow journalism, Rampton and Stauber (a.k.a. Special Agents Fox Mulder and Dana Scully) set out to prove that behind every successful corporation in the United States, is an infinite network of diabolical wizardry attempting to "pull one over" on the innocently misinformed American public. In fact, by their account there is a conspiracy of public relations firms, billionaire sugar daddies and scientists for hire, all with one thing in common: their insatiable greed and disregard for the American public's best interest.United StatesThis idea of conspiracy is not new of course, the DNC and Clinton administration have been crying wolf since the Lewinsky scandal of 1998. This notion of conspiracy theory is basically an agreement to perform together an illegal, wrongful, or subversive act. An act of conspiracy is exactly the way to describe American Communists and their fellow travelers, who did everything from infiltrating government to stealing the secrets of the atom bomb. Every now and again we hear about people who reveal insightful conspiracy theories that Wall Street is planning another depression, or that AIDS was an invention of the CIA to arrest the growth of the African American population.Trust Us offers examples ad nauseam of these sorts of conspiracy shenanigans, but essentially becomes a repetitive list of treacherous acts performed by some members of the PR industry. In short, the book is completely anti-corporate and almost entirely...
