Monitoring U.S. citizens' phone conversations to detect potential Essay
Monitoring U.S. citizens' phone conversations to detect potential terriorist threats - Essay Example Such provisions threaten the quintessential American way of life. Liberty and freedom have always been a fundamental part of the American ethos and values. The very spirit of American political life and popular expectations simply do not allow the state to extend its sway beyond a point where it not only interferes with the personal and professional lives of people and individuals, but rather tempers with the privacy of their private and professional phone conversations. National security is really very important. However, the concerns for national security cannot be allowed to irrationality expand to a level where they start hampering the normal activities of the citizens. The act of monitoring the phone conversations of citizens is also unconstitutional and violates the Fourth Amendment rights of the citizens, which constitute a part of the Bill of Rights (Dripps, 2007). Superficially speaking, the Fourth Amendment to the constitution of the United States of America intends to prot ect the citizens from illegal search and seizures. Surprisingly, the very purpose of this Amendment was to check the abuse of general search warrants in the American Revolution (Dripps, 2007). In the historical Katz v.

Language Evolution and Syntactic Theory Essay Example | Topics and Well Written Essays - 8500 words
Language Evolution and Syntactic Theory - Essay Example Category one and two combine when considering that the "universal characteristics of language may be so because they are aspects that make it more easily acquirable."2 The evolutionary nature of language is a new category of investigation that attempts to determine what occurred in our ancestral lineage that gave rise to a form of communication that is distinct from other species. This category involves genetics, paleontology, and archaeology. However, whereas these studies benefit from a rich fossil record, evolutionary linguistics suffers from a lack of evidence. To overcome these shortcomings, linguists often make use of studies in the four categories already discussed. However, Kinsella's research is unique in that it will not rely on the four categories. Instead, she utilizes evidence from evolutionary studies that will shed a critical light on the theory of linguistics. The essential argument Kinsella makes is that this research is a step in developing a more unified theory of linguistics. This is much like psycholinguistics or neurolinguistics before it, which incorporate diverse disciplines in founding new conclusions. Kinsella frames the current discussion on language within syntactic theory. She criticizes these theories for relying on theories that are based only in linguistics and don't incorporate multi-disciplinary perspectives in their analysis. She contends that syntactic theory needs to be critiqued not merely as a means of recording observable data. In addition, syntactic theory must also be critiqued as a theory of language that must be consistent with theories in other fields. While she acknowledges that there are many competing syntactic theories, the research focuses on the Minimalist Program and contrasts it with theories in evolutionary biology to test its validity. It's notable that the analysis focuses the validity of the linguistic side and not the biological side. This seems to be due to the foundational role evolutionary biology plays in the Minimalist Program. Also, there is a continued view of linguistic philosophy as a 'soft' science. Kinsella is vague in distinguishing the exact specifications of the Minimalist Program. She writes that, "...syntactic theory tells usthat the grammatical structure of language is the mediator between signal and meaning"3 and references Chomsky as privileging the internal aspects of language over the external. While she discusses the MP's emphasis on creativity within syntactic structures, it seems that she is ultimately positioning it as a strongly internal theory of languag

PP3003 Research Question Paper Essay Example | Topics and Well Written Essays - 3000 words
PP3003 Research Question Paper - Essay Example Milward suggests that the founding fathers of the EU actually intended their states to maintain sovereignty in the system and that only by binding the economies of the states to some extent together could their independence in a rapidly changing world be maintained. As Milward wrote in his The European Rescue of the Nation-State, "The reinvigorated nation-state had to choose the surrender of a degree of national sovereignty to sustain its reassertion . . .â⬠(Milward 1992) The post-war system was such that European states would have had a harder time existing if they did not rely on one another. Without the EU they would not have as much independence as they have today. This is an interesting argument but is not a convincing one. It is one that makes more sense in the 1990s than it does in the aftermath of the recent expansion and economic crisis. The truth is that by overreaching, the EU has come to damage the independence of the nation state. Countries such as Greece and Irela nd have given up a great deal of sovereignty in recent months (Brown 2011). The EU bureaucracy and power have grown dramatically and eclipsed weaker countries. The EU has become, in some senses, a monster that has a life of its own. Nation states are vanishing within its bailout mechanism and refusal to allow individual devaluation. Milward's argument may have made more sense when he first made it but time has not been kind to it. Bomberg, E. (2003): The European Union: How Does It Work? (The New European Union Series). Oxford: Oxford University Press. Brown, JM (Jan. 2011): "How the Celtic Tiger Lost its Roar", Prospect. Milward, A (1992): The European Rescue of the Nation-State. New York: Routeledge. 2) What impact did the ECJââ¬â¢s rulings in the Van Gend en Loos and Costa cases have on the development of the EU legal order? The rulings led to the establishment of the fact that the treaty creating the EC also created a new legal order, effectively creating a supra-national bod y of law. The Van Gend en Loos case related to tariffs between companies (Barnard 2007). One country wanted to raise a tariff on a chemical but this was found to breach EC law, as the purpose of the treaty was to reduce tariffs between countries. For the first time, it was determined that countries were required to obey rules higher than those created in their own legislatures. The countries of the EC were binding themselves together with new laws that in many senses encroached upon their independence and sovereignty. This case created the doctrine of direct effect, which was perhaps not foreseeable some of the new signatories to the EC treaty, whereby provisions in the treaty could have direct legal effect and overpower their own domestic law. Costa is a case that confirmed this idea. EC/EU law is paramount where a conflict occurs between the two laws. This has since been somewhat weakened by many national courts which suggest that this type of paramountcy only really occurs when t he EU law is in sync with the national constitution of the affected country. Not every EU law will therefore be paramount over every national law. There is some room to manoeuvre (Kent 2001). We can see from this important rulings by the ECJ the beginning of the legal order of the EU superstate. There were many unforeseen consequences to the signing of the first treaty and the beginning of ever closer union. Many legal
Scarcity Assignment Example | Topics and Well Written Essays - 250 words
Scarcity - Assignment Example A need is something that is tremendously essential for a human being to survive. It is that thing that people cannot live without; they must have it in order to stay alive. In addition, it is that one thing that people cannot function without that one thing that people must have. If a requirement is not met, it would probably result to the beginning of a disease (Bomstein and Susan 135). Also, when the need is not met, it leads to a personââ¬â¢s inability to function effectively. The lack of needs also makes it hard for people to purpose professionally in a society. Therefore, when the need is not met it can likely lead to death. Normally, needs remain steady all the way through the lifetime of a person. Conversely, wants are something that an individual wishes to have in life. It can be that thing that a person longs for either right away or in prospect. They are not essential for a personââ¬â¢s survival people can live without wants. Wants normally vary from one individual to another. Every individual has her or his list of wants, all with unreliable level of significance. In addition, wants can vary over a point in time (Bomstein and Susan189). Some of the examples of needs are; food, the air, shelter, water and clothing. On the other hand, wants are a nice car, travelling abroad, ice cream, designer t-shirt, nice shoes. The idea of my choice is based on the necessity and the most desired things by majority of the

Advantages and disadvantages of internet Essay Example for Free
Advantages and disadvantages of internet Essay Nowadays internet is the most common form of communication. It is a worldwide connection of computer systems over a massive network. There are certain advantages and disadvantages to the Internet. First of all internet has made communication very simple, easy and convenient. It is possible to stay in touch with people that you hardly ever see. Moreover internet is a source of knowledge. Anyone could simply open internet and get many information about anything. In other words it is a small encyclopedia about everything in the universe. Nothing online is trustworthy. Websites that are supposed to be trusted and are supposed to be reliable are not full of reliable information. Even major websites that are run by big and trusted companies are using writing firms to write their websites and the writing firms are simply hiring the cheapest freelancers to do their work for them. It is true that the Internet has made it easier to find out basic facts such as the location of places, but even that information is commonly incorrect. Also some people use the Internet too much and forgot real life contact. It may now be easier to keep in contact with people you know, but it has removed any incentive to visit people. In other words it can be addictive and a waste of time and even money. Two angles have been compared in both a positive and negative light. Internet can be useful and dangerous at the same time. In my opinion, Treat the information you read online with a high degree of skepticism and you will be alright. It is also a good idea to use the Internet in order to stay in contact with people, as it is easy and convenient. However, do not allow online contact to start replacing physical contact. It is important to strike a balance between the two.

The Last Judgment Essay Example for Free
The Last Judgment Essay The painting of ââ¬Å"The Last Judgmentâ⬠by Michelangelo was a fresco which was executed between 1537 and 1541 at the behest of Pope Julius II who commissioned Michelangelo to perform the task. This scene is based on the passage in the Bible on what would happen when Christ would come again. Both the living and the dead, who would be raised then, will be judged by Christ and their fates would be determined if they are going to heaven or hell. The artwork was done on freshly spread lime plaster that was still moist with water-based pigments. Michelangeloââ¬â¢s palette developed highly embellished monochromatic work and the symmetry of his figures made it appear broader and more threatening, if not intimidating to the uninitiated, intended to evoke a sense of awe to anyone who would view it. This large, solid and heavy wall painting can be viewed behind the altar wall of the Sistine Chapel in Vatican City and it took Michelangelo more than four years to complete this masterpiece which was a break from the usual sculptures he used to do where he had made outstanding works such as ââ¬Å"David,â⬠ââ¬Å"Pietaâ⬠and ââ¬Å"Mosesâ⬠as he dabbled with the concept of mural painting which was probably the largest masterpiece he had ever done in his life as ââ¬Å"The Last Judgmentâ⬠formed part of the vast murals that adorn the walls of the chapel which is the Popeââ¬â¢s private chapel and at present, a place with significance as this is where Popes are chosen during conclaves and ââ¬Å"The Last Judgmentâ⬠is considered an appropriate artwork to adorn the altar of this historic chapel for such an occasion. The ideas and sense of appreciation from the painting itself depicts the individuality of every personality on the artwork. They each have varied deep explanations of every detail in the painting. Explanation is on the basis of their own experiences in relation to the painting and to themselves. Each dimension of this painting has its own perspective to present making it open to various interpretations. Oneââ¬â¢s eyes have to move from the center going up then look down after in analyzing overall the images then breaking it down to individual parts. The meticulous ones would be made to zoom in to see the every little detail, thinking whether it has connection or relevance with other images. The painting itself provides varied insights and explanations allowing for varied ways to comprehend the painting. For instance, the angels in the middle of the paintings are depicted blowing their trumpets to raise the dead, shown on the lower left-hand side of the painting, from their long deep slumber to prepare them for their appointment with God. Two of them, apparently the archangels Michael and Gabriel are seen holding the two books in which all has been written down about the individuals where Jesus will base his judgment. The smaller book contains the names of the ones to be saved while the larger one contains the names of the damned (Michelangelo; Ruehling). This is consistent to what is stated in the Gospel according to Matthew. A similar passage would be also stated in the Book of Revelation (Rev. 20:11-15): ââ¬Å"When the Son of Man comes in his glory, escorted by all the angels in heaven, he will sit upon his royal throne, and all nations will be assembled before him. Then he will separate them into two groups, as a shepherd separates sheep from goats. The sheep he will place on his right hand, the goats on his left (Matt. 25:31-33). â⬠On the left panel, the chosen ones situated on the right side of Christ, those who had been judged worthy are escorted to heaven by the angels where they would live eternal bliss with the Almighty. The right panel, on the left of Christ shows the damned, the ones deemed unworthy and proven to now have repented their sins, are being led to hell where they would suffer eternal damnation (Michelangelo). Besides the Bible, Michelangelo got his inspiration for making his artwork from Dante Alighieriââ¬â¢s ââ¬Å"Infernoâ⬠as it provided him with graphic detail or has enabled him to ââ¬Å"flesh outâ⬠the scenes he would be depicting. In addition, he added personalities and characters from Greek and Roman mythology as part of his ââ¬Å"fleshing outâ⬠of the scenes (Barnes 1). One would be able to recognize Charon (holding an oar), the ferryman of Hades of the Greek mythology as he and his minions are seen leading the damned to be judged before Minos found at the extreme lower right-hand corner with a snake wrapped around his body. Minos is another figure in Greek mythology where he was the king of Crete but in this case and using artistic license, Michelangelo depicts the Cretan king as the ruler of hell instead of using Hades or Satan. Jesus is situated in the middle, befitting his stature as the King of Kings with his mother Mary at His side. The two large figures flanking Christ are the disciples Saints John the Baptist on the left and Peter on the right, depicted with keys of heaven in his hand. The figure underneath and further right of Jesus is another disciple Saint Bartholomew, whose image is a self-portrait by Michelangelo himself. Also included are most of the saints who were martyred. They are seen in the painting holding the instruments of their martyrdom such as Saint Sebastian holding arrows used to kill him; Saint Blaise, holding iron combs used to torture him to death and Saint Bartholomew holding his skin, underscoring how he was flayed (skinned alive) to death by his tormentors (Michelangelo). Above the lunettes are symbols of the Passion of Christ which are the cross, the crown of thorns, the pillar where Jesus was bound and scourged, the spear that was used by Longinus to stab his side, and the sponge dipped in vinegar and hyssop used to sate Christââ¬â¢s thirst while hanging on the cross. In terms of scale, technique and drama ââ¬Å"The Last Judgmentâ⬠is an absolute highlight of Renaissance painting as one can see the humanist approach taken by Michelangelo that showed a return to the classical style of Greco-Roman influence and a complete departure from the medieval style which was formless and lacking depth. Originally, most of the images were depicted in the nude but owing to the sanctity of the place, a certain degree of modesty and decency was exercised and it fell upon Michelangeloââ¬â¢s assistant, Daniele de Volterra to ââ¬Å"editâ⬠the painting by covering the private parts in such a way that it did not compromise the intention of his mentor to depict the well-proportioned bodies of his subjects (Barnes 88). Jesus Christ: Physically, Michelangelo depicted Christ with broad, powerful proportions, appearing in a radiant glow of divine light befitting His place as the Son of God and King of Kings. Michelangelo further accentuated this radiance by painting the figure in a section that is best illuminated by the chapels window for ââ¬Å"special effect. â⬠Christ is portrayed barely clothed and bare-legged instead of being majestic as one would expect in his Second Coming, wearing only a long strip of cloth across his loins in a manner in order to reveal the wounds of his crucifixion ââ¬â the puncture wounds on his hands and feet where the nails were driven and the wound on his side where the spear was thrust. These not only emphasize his passion as well but also resonates images of his resurrection, proving once and for all that he had conquered death and has redeemed mankind from the wages of sin and thereby emphasizing his undisputed position as the ultimate judge of mankind (Ruehring). Despite the rather ââ¬Å"modestâ⬠image of Christ, Michelangelo still managed to evoke a powerful image of Jesus as final judgment is being carried out without fear or reservation in order to justly and ultimately determine who deserves to be punished and committed to hell. Michelangelo depicted Christ in such a way to express the righteous anger of promptness and firmness in passing judgment towards the individual, further reminding one of the fate that awaits when that time really comes. The painting also depicts the Blessed Virgin Mary seated beside Christ. Mary is regarded by Catholics as a great intercessor for anyone seeking solace or succor in times of trouble. In this particular case, she appears to be downcast as her head appears to turn away as a sign of resignation which implies that she could no longer intercede for anyone at this point in time and can only be a spectator witnessing the judgment of mankind (Michelangelo; Ruehring). Minos: At the lower right-hand corner of The Last Judgment is Minos, whom Michelangelo depicts as the king of hell instead of Satan. It can be inferred here that Michelangelo employed artistic license in using a different character to be the ruler of hell and he drew his inspiration from Danteââ¬â¢s work ââ¬Å"Infernoâ⬠where Minos is depicted as the king of hell (Alighieri 23,75). He is shown with a serpent wound tightly around him, symbolizing the circle of hell. Michelangeloââ¬â¢s physical depiction of Minos also served for him as a stinging caricature against his enemy Biagio da Cesena, then the Popeââ¬â¢s chamberlain, as a way of getting back at him for saying his painting was not worthy to adorn the walls of the Vatican despite the commission from the Pope. Michelangeloââ¬â¢s spite was very evident as he tried to depict Minos in the most hideous way possible complete with asss ears and a serpent striking his genitalia as a form of ââ¬Å"revengeâ⬠against his nemesis whom he could not physically harm owing to his stature in the Vatican (Ruehring). Charon: Michelangelo borrowed another character from Danteââ¬â¢s work and Greek mythology in Charon, the boatman who ferries the souls of the dead across the River Styx leading to Hades though in this case, it is hell. Physically, Charon is depicted hideously with dark skin, thick dark hair, pointed ears, bulging and glowing eyes, giving him a devil-like appearance, short of depicting him as an actual demon. He is depicted herding the darkly gaunt and tortured souls as they spill upon the shores of hell. Michelangelo has truly captured Charon as an agent of hell in this painting and seamlessly combining classical (Greek) mythology with Christianity to come up with a very strong image (Barnes 108, 113). All in all, ââ¬Å"The Last Judgmentâ⬠can be truly be called a masterpiece by Michelangelo. He had done justice to the work and in a way, rendered great service to the Church by blending horrors and beauty; of condemnation and redemption, all these wonderfully captured in his painting.

Carbon Fiber Reinforced Polymer (CFRP) Uses and Properties
Carbon Fiber Reinforced Polymer (CFRP) Uses and Properties CFRP: carbon fiber reinforced polymer Urvish Gajjar In the end of 1800s first time Edison used the carbon fiber in the electricity bulb. CFRP- carbon fiber reinforced polymer is a one type of the carbon fiber. Edison used the fiber into the filament of bulb but he was unsuccessful because his fiber produced by carbonization of cellulose stand such as cotton or from bamboo. Because of the not specific design and not specified properties his fiber was failed. Then after that time the research was start on fiber and in the middle of the 19th century carbon fiber used in insulation or in high temperature furnaces and in the industries like chemical plants and mechanical plant where we need some strength material. Before end of 19th century the increment shows in the carbon fiber field when the manufacturing process developed very well and allows for high modulus and high powerful fiber the reinforced process apply to the fiber and then they find the new type of carbon fiber which is CFRP. In Japan, first time work done in the CFRP field by 3 scientist of Japanese bureau of industrial technology. They were using poly acrylonitrile ââ¬â PAN in the base material to manufacture carbon fiber this fiber had a high degree of molecular orientation. Then from that days the improvement is in process and now a days we can use PAN is major material in common use. The high stiffness and strength properties and low mass of CFRP have lead to more use in the aircraft and other industries. In 1977 CFRP use as skins in the aircraft. It was used in the vertical fin box and leading edge in the F-16 air force aircraft. CFRP has a very different properties one of its property is a very low co-efficient of thermal expansion thatââ¬â¢s way it can used in space air craft because space aircraft has been work in the galaxy and there the temperature is between -110c to90c. Then in the 1980 CFRP was taken as reinforcement to strong then concrete beams then they people use carbon fiber poly mer in reinforced process and got the CFRP. So thatââ¬â¢s a short past about the carbon fiber reinforced polymer In the synthesis or in making of the structure of CFRP in this composite more than two materials can be use so in the first step one material can be take as a basic or supporting matrix and at that time the second material build a structure on that base and reinforced the the hall material . this process is a very complex and costly .this hall process can be work under the certain temperature and pressure . After this process an epoxy can be filled out on the base material and make a hard and strong material then after the material cooled out . the mixture can produce by fiber of the different material in the main matrix. This way we can produce the CFRP from the carbon fiber. Fig 1. CFRP bond view In the Fig 1 we can see the large view from the gap of the two layer and how to build the layer of the polymer. In the aircraft the part of the aircraft need a strong tensile strength and the need the material which can not react on the environmental condition. So CFRP satisfy all this condition so it can be easily used in the aircraft industries for making the wings, tail of the aircraft For aircraft most important is the properties of the material which is used in manufacturing of aircraft because if the material has not sufficient properties related to aircraft it can be fail in future . CFRP is a one type of composite material. So it has a mixture of the two material so, it has two different kind of properties of two different material. CFRP has two part one is matrix and another is reinforcement. Second part is fiber so they give a high strength and first one is polymer which give a rigidity.In that because of carbon fiber CFRP has a high modulus of elasticity. And also have a low density, high tensile strength and last one is most important which low chemical reaction which is most useful properties for aircraft material. Fiber has a many different type of composite material but CFRP is a special one because it has a many positive properti9esw and many advantage given composite material the start with itââ¬â¢s advantage CFRP is a very strong material but with the extremely light weight it has been used in internal part of aero plane and carââ¬â¢s structure. The good thing about the CFRP is it has a high strength, rigidity, resistanc3e and low corrosion. so thatââ¬â¢s way it is use in various important structure component. There are in composite material other material also have a good properties but CFRP is manufacture in specific condition so because of that reason CFRP has a good properties then other composite material .especially in field of aviation and space lights. This reinforced polymer s are the incredible potential see on other benefits of this material is that it is a low thermal expansion so it cannot more contract orexpand in such a different thermal condition. CFRP is a less corrosion properties because when the material manufacture with the specific resins, carbon fiber is used ant this one is a most corrosion resistance material so it is a less corrosive. We see the different advantage of CFRP is durability, radiolucency, electrical conductivity and ultra-violate resistance. CF is transparent to radian and invisible in X- rays so CFRP is radiolucency. Every material has a benefits and a drawback. CFRP also have some disadvantages. This material is very costly and its structure is very complicated and complex. It is a creep, low flexibility and brittleness material. In its disadvantage one of the major is that in the manufacturing time if there some mistake happen or process run improperly themn the hall material is useless and we can not use that material any more. So in itââ¬â¢s production time have to very carefull and we need special skilled worker. CFRPââ¬â¢s uses are increase day by day because now a days people need a reliable and easy accessable products. CFRP is a l0ow weight and good properties so people used this composite material in different field . In aerospace industries there are highest use of this material In past first aircraft made by composite material in that almost half percent material is CFRP. Then the branded car rolls-royce also use this material in that cars and bow a days in automotive, civil thatââ¬â¢s all engineering field increase the use of the CFRP. If we see the different field like a sports , music and kitchen thaqtââ¬â¢s goods are make from the CFRP. In in future in this world mostly products are make from the carbon fiber. Second, in medical field dentist use the machine for operation thatââ¬â¢s all are made from carbon fiber. So, we see small part of machine to Hugh aircraft all where we use this material. Fig. 2 composite material used in aircraft Source:educare-zone.blogspot.com If we see from environment engineering site, the nature is give a high thinking and attention from todayââ¬â¢s community. This is right for composite material as well. As we see ahead , that composite material is a light weight and high strength, thatââ¬â¢s affect the environmental but it is low compare to real material like steel. Yes some time if we make a wrong composition for material that time its affect the nature .polymer is only affect by itââ¬â¢s pollution not other way. So, at last, CFRP is a good composite material if we use it perfectly References History of carbon fiber http://www.hj3.com/company/history-of-carbon-fiber/ Sarah Lynn Orton.
