Project - Research Paper Example Even though both sexes carry the mutation, the females rarely exhibit the signs of the disease. The symptoms may be visible in early infancy and appear in male children before the age of 6. Laboratory testing can establish the children who carry the active mutation at birth (Dalkilic & Kunkel, 2003). At first, progressive proximal muscle weakness of the pelvis and legs that are associated with a loss in muscle mass. Eventually, this weakness spreads to the neck, arms and other areas. The early signs consist of enlargement of the deltoid and calf muscle, difficulties in standing without help, and low endurance. As the condition progresses, there is wasting of the muscle tissue. By the age of 12, most patients are usually dependent on the wheel chair. Symptoms that occur in the later stage include abnormal development of the bone that leads to deformities of the skeleton. As a result of muscle deteroriation, there is occurrence of the loss of movement, in the long run it leads to paralysis. The average life expectancy for the DMD patients is about 25 years. The diagnoses of the disease include DNA testing, muscle biopsy, and prenatal tests. First, the muscle-specific isoform of the dysrtophin gene is made up of 79 exons. DNA tests and analysis determine the particular type of mutation of the exon (s) that is affected. Secondly, muscle biopsy entails extraction of a small sample of muscle tissue. A dye is then applied to reveal the presence of the dystrophin. Lastly, prenatal tests establish if the unborn child has the most common mutations. The X-linked recessive gene carries the DMD. Males have one X chromosome implying that one copy of the mutated gene will lead to DMD. The mutation is transferred by the mother since fathers cannot pass the X-linked traits to their sons. When the mother is a carrier, one of her X chromosomes has a DMD mutation. In that respect, there is 50 % chance that the

Factors For The Rise Of English Neologisms English Language Essay

Factors For The Rise Of English Neologisms English Language Essay Languages are changing as the world is constantly changing. After the Second World War, English neologisms emerged in a remarkable way. New vocabulary came into existence due to new technologies and new discoveries such as ; computing, internet , cell phones and the like. Peoples daily activities like dancing, looking and many others, renewed their popularity giving birth to new lexicon. In deed, new words are invented rapidly and are developed quickly thanks to mass communication. They appear and fall into disuse when they have served their momentary purpose ( Bernhart 54).Only a few of them will get recorded in glossaries of neologisms of general dictionaries. The matter of neologism becomes a new hot spot of research owing to its practical and prevailing use in reality. The study of neologisms evoked a whole cluster of questions: -What are the reasons beyond the rise of new lexicon? -Why are some new words just a flash in a pan? -Why are other words successful? -What are the qualities that make a word successful? -Are Neologisms markers of changes in societies? Part 01: Literature Review 1.Definition of a Neologism The term neologism originates from Greek: neos means new, logos means word, i. e. a neologism is literally a new word. Neologism is the creation of a new lexical item as a response to changed circumstances in the external world, which achieves some currency within a speech community(qtd. in Chrystal 1992: 264) at a particular time. In linguistics, a neologism is a newly invented word or phrase. It can be an old word or phrase used with a new meaning. The word neologism is a neologism itself, it was coined in 1800. l. 2. Background of English Neologisms The collection of dictionaries that contain neologisms started in 1604.The early Neologisms dictionarieswere: Table Alphabeticall (1604, Robert Cawdrey), English Expositor (1616, John Bullokar), and The English Dictionarie (1623, Henry Cockeram).Those dictionaries had some features of neologisms dictionaries but the true study of neologisms began in the 20 century, some 200 years later. The first neologisms book is Word-Coinage, being an Inquiry Into Recent Neologisms, also a Brief Study of Literary Style, Slang, and Provincialisms by Leon Mead in 1902.It was not a real dictionaries, it contained a set of articles about new words. In 1920, there was a remarkable progress in the research of new words with the book of C.Alphonso Smith entitled New Words Self-defined.it included 420 new words with examples.He wrote some articles entitled Words and Meanings, New. . From 1937 to 1940, Dwight Bolinger ( Famous American Scholar) invented a column ,The Living Language, in the newspaper, Words.Later, it was changed into Among the New Words.In 1944, Professor I. Willis Russell became the editor of this column . World War II was a major reason of the birth of new words .In 1944, Majorie Taylor collected the new words created during the War in a word-list entitled The Language of World War II: Abbreviation, captions, Quotations, Slogans, Titles and Other Terms and Phrases.At the same time, Clarence Barnhart printed his Dictionary of U.S. Army Terms. After the World War II, science and technology development had greatly effected the society. A lot of scientific and technical words were brought into language. A lot of neologism dictionaries about words in those fields were published. Two of them are mostly welcomed: An Explaining and Pronouncing Dictionary of Scientific and Technical Words by W. E. Flood Michael West and Words of Sciences and the History Blind Them by Isaac Asimov. From 1970s on, the study of English neologism drew great attention from western scholars, many of them established special column to introduce new words in English, such as William Safire who was well known for his On Language in New York Times weekly and Anne H. Soukhanow who was the chief-editor of Word Watch. In Safires column, he provided a considerably clear explanation of new words by citing typical examples, exploring their origins and performing their current usage. The digital revolution in 1990s is the radical reshaping and restructuring of social patterns. Because of the wild spread of internet, America is speaking a whole new language, said Shawn Holley in his The New Word Revolution. Lots of neologisms that have a historical significance by reason of the influence they exerted on the language field are brought into existence. According to the statistics, more than 20 neologism dictionaries have been compiled, among which some put emphasis on the academic field and some are distinctive by their popularity. Oxford English Dictionary, Websters Third New International Dictionary and Barhart Dictionary of New English are the ones with the highest academic value. New words are numerous. Sometimes it seems as if a new word has about as much chance of developing into a permanent addition to our vocabulary. Only few of them will remain as serious candidates for the dictionary. Books especially about new words are abundant. However, only a few scholars have ventured to propose factors that make for the success of new words. One is Goran Kjellmer, whose article Potential Words in the journal Word for August 2000 also reviews previous proposals. The other is the executive secretary of American Dialect Society, Allan Metcalf who proposed the FUDGE scale. The two reached different conclusions. Along with books and periodicals, there is the Internet. In particular, it makes my extensive searches for examples of how words are actually used today possible. Here the author has searched thousands of pages indexed by Google.com countless times to find current uses of words under discussion. A jump of several decades has showed us more researches on the neologisms. Language reflects our life, and the research on the neologisms has never been stopped. By collecting new words or phrases occurring in languages, the previous researches have provided precious materials for the further exploration in this field. Therefore, a careful look at the research background of neologisms carries an essential academic significance. In china, the study of neologism began from 1980s. Most of the specific works and papers are mere introduction of theories from abroad lacking of much original study. To keep up with the latest English vocabulary is really difficult, thus a thorough and systematic analysis about English new words is of practical significance both in learning and teaching of English as a foreign language. Part 02: Factors for the Rise of English Neologisms The resaons beyond the rise of new words are numouroes, some are internal causes or linguistic (phonological, morpho-syntactic, lexical or semantic) , others are external which , we will see in this part. Mcmahon M.S (1994: 179-182) discusses causes of semantic change and describes the following: Linguistic causes Historical causes (subdivided into ideas and scientific concepts) Social causes Psychological causes (subdivided into emotive factors and taboo) Foreign influence The need for a new name 2.1. Sociolcultural Changes: 2.1.1. New ideas in Society and Culture. Changes in social outlook and manners of behavior call for new terms such as beatnik, peacenik, and hippie. Even new culinary arrangements demand new labels and in English they have some forth in the form of cheeseburger, chiliburger, mushroomburger, etc. (Anderson, 1973) Brian Foster presents us a striking example of how fast English vocabulary changes. In the year 1914, a young girl named Monica Baldwin entered a convent, remaining secluded there until 1941. When she returned to the outer world, she found herself in a totally different world: the conditions of everyday life altered by technical developments and social changes were beyond recognition. Whats more puzzling to her was the language people speaking. During a railway journey, the term luggage in advance meant nothing to her. Reading the daily newspapers made her feel idiotic in the extreme, because words like jazz, Gin, Hollywood, Cool, noshing and Isolationism were completely incomprehensible to her. Not to mention how bewildered she was at hearing friends say, Its your funeral or believe it or not. (Brian Foster, 1981) 2.1.2. Disguising Language, Misnomers Misnomers are words that replace taboo words or banned words.In order not to deceive the hearer, the taboo words are replaced to disguise their unpleaseant meaning.Examples: E. friendly fire instead of bombardment by own troops. 2.1.3.Prestige, Fashion The superiority of a group or politics leads people to use some linguistic elements (words, morphemes, morphs, sounds) from the prestigious group. Example: English, for instance, borrowed from French during the ME. period because the upper social classes were made up of French people:e.g. garment, flower, rose, face, prince, hour, question, dance, fork, royal, loyal, fine, zero are all Gallicisms. An other vivid example is English which is now the most prestigious language in many parts of the world. 2.1.4.Social, or Demographic, Reasons Here, it means the contact between different social groups. As a result of this contact, new lexical items appear. In the history of the English language, the two prominent instances of exchanges between two social groups were the one with the Vikings in the 8th to 11th centuries and the one with the French in the 11th to 15th centuries.Examples: The inherited ey is replaced by Scandinavian egg, the inherited nimen is replaced by Scandinavian taken except for theform benumb, throwen is supplemented by Scandinavian casten; early French loans are army, carpenter, catch. 2.1.5.Culture-Induced Salience of a Concept (Cultural Salience) The salience or the importance of concepts change with change of culture. Example: In the US, a lot of metaphors in general language have been taken from the field of baseball, e.g. to be off base to be completely wrong, to hit a home run to be highly successful and from the field of entrepreneurship. 2.1.6.Word-Play The category of word play includes humor, irony and puns. Although word-play often goes hand in hand with other factors (such as taboo, prestige or anthropological salience), it can also trigger lexical change on its own. Example: to take French leave to leave secretly (without paying), to cool look ( 2.2 Technological Changes New science leads to new words. Aristotle and Newton were neologists.They used new lexicon and new defintions to explain the theory of dynamics Thus, there is no new knowledge without new terms or concepts.Generally a new invention or discovery holds the name of the inventor. Sometimes some technical new words can be found in linguistics such as hypercorrection, allomorph, etc. The word software for example, that computer term was invented by John W. Tukey, a statistician at Princeton University. As long ago as 1958, he used the word in the American Mathematical Monthly. Today the software comprising the carefully planned interpretive routines, compilers, and other aspects of automotive programming are at least as important to the modern electronic calculator as its hardware of tubes, transistors, wires, tapes and the like. Tukey was already known for inventing another now- famous computer term. 2.3 Economic Changes Economic field has a great impact on language.We are in a competition age.This leads to new brand names that want to find a place in the economy market.The success of the product causes the suceesss of its name.The owner of the product has to spend too much money to make the prdut well-known.This is done via advertisemnts to convice peole tp but it and name it as it was advertised.Its name will be a new word in the society. The example of Coca-Cola Company is a good example.due to the geat success of Coke, people can ask for a coke yet they will be satisfied if they are given pepsi , i.e. the word Coke nowadays refers to a soft drink like a coke. Some technical and medical brands find their way in general vocabulary. Examples: à ´Ã¢â€š ¬Ã‚ Ã‚ ºÃ¢â€š ¬Ã‚  Aspirin: a name for acetylsalicylic acid, trademarked by the Bayer Company of Germany at the start of the twentieth century. à ´Ã¢â€š ¬Ã‚ Ã‚ ºÃ¢â€š ¬Ã‚  Elevator and escalator: both originally trademarks of the Otis Elevator Company. à ´Ã¢â€š ¬Ã‚ Ã‚ ºÃ¢â€š ¬Ã‚  Zipper: a name given to a separable fastener by the B.F. Goodrich Company many years after it was invented. The new name helped the zipper attain popularity in the 1930s. à ´Ã¢â€š ¬Ã‚ Ã‚ ºÃ¢â€š ¬Ã‚  Loafer: for a moccasin-like shoe. à ´Ã¢â€š ¬Ã‚ Ã‚ ºÃ¢â€š ¬Ã‚  Cellophane: for a transparent wrap made of cellulose. à ´Ã¢â€š ¬Ã‚ Ã‚ ºÃ¢â€š ¬Ã‚  Granola: a trademark registered in 1886 by W K. Kellogg, now used for a natural kind of breakfast cereal. à ´Ã¢â€š ¬Ã‚ Ã‚ ºÃ¢â€š ¬Ã‚  Ping-pong: for table tennis, a trademark registered by Parker Brothers in 1901. à ´Ã¢â€š ¬Ã‚ Ã‚ ºÃ¢â€š ¬Ã‚  Xerox: for photocopier. à ´Ã¢â€š ¬Ã‚ Ã‚ ºÃ¢â€š ¬Ã‚  Kleenex: for facial tissue. à ´Ã¢â€š ¬Ã‚ Ã‚ ºÃ¢â€š ¬Ã‚  Band-Aid: for adhesive bandage. à ´Ã¢â€š ¬Ã‚ Ã‚ ºÃ¢â€š ¬Ã‚  Tupperware: for storage container. à ´Ã¢â€š ¬Ã‚ Ã‚ ºÃ¢â€š ¬Ã‚  Scotch tape: for transparent adhesive tape. à ´Ã¢â€š ¬Ã‚ Ã‚ ºÃ¢â€š ¬Ã‚  Jazzercise: for exercise to jazz music. 2.4. Political Changes. Some important political changes infulence vocabulary and give birth to new words and concepts. For instance, when Mr. Bill Clinton was elected as the president of the US. His name has been associated with many political words. His policy is Clintonian, he is carrying out the Clintionism, his economics policy is Clintonomics, and his supporters were called Clintonites, he ultimately wanted to realize his Clintonization. Another recent political event that took place on Septembet the eleventh has brought a neologism in the American society.Because of the striking coincidence that 911 is the telephone number to call for help in an emergency, that numerical designation of this event has been a success. The events of that day have resulted in a new term: ground zero, for the place of impact, the center of destruction in New York City where the World Trade Towers once stood. That phrase has succeeded because it is not really new; its an old term for the location on the ground directly under a vast atomic explosion, corresponding to air zero, the location in the air above the ground where the bomb goes off. No one knows who first said ground zero in reference to the site where the World Trade Towers were attacked and collapsed, but the term immediately caught on because of its familiarity and emotional power. Part 03: Success of English Neologisms In the previous section, we have seen the reasons of the rise of the new words and how they become part of language.In this part; we will tackle the reasons that make a word successful or the reasons that make a word part of general language dictionary. 3.1 The occurrences The frequency of the new word in a society makes it successful.If the neologisms appears in many various sources such newspapers, magazines and books, it will be included in general dictionaries and becomes a familiar word and no more neologism.This mean the the word becomes popular if it is cited in many sources 3.2 Variety among sources A neologism in its first appearance is common for only a special field .Thus, it is found in technical dictionaries .Consequently , general dictioanries exclude technical terms .But there are some exceptions and some technical words find their place in general dictionaries due to their range in many sources.Example , the phrase intellectual property was limited to some branches .Nowadays, it is widely spead thanks to the new technologies and inventions in each field . 3.3 Cruciality in a given field Sheidlower defines cruciality as the need for a word to exist (35). Lets take the example of the acronym AIDS invented in 1982.This acronym is still the given name to this killing disease.It will hold the same name even if a cure is invented for this disease because of the importance and cruciality of this sickness, its referent is a crucial matter in society (qtd. in Sheidlower 35). The word whirlpooling, though it is the only word used to describe such a behaviour, it is not included in a general dictionary because the phenomenon is rare and unusual , rare and unusual phenomenon (qtd. in Sheidlower 36). 3.4 Durability or Endurance ( Existance) Each new word appears in a specific period of time.But if it has suffiecient evidence such as frequency of occurrences, range among sources, cruciality in a given field, it may be included in a general dictionary. New Deal is a good example here.So some neologisms refer to their time period, culture, policies and the like. Conclusion If a word wants to stay alive, it has to be admitted widely in public speech and used by mass media, and/or personalities, such as politicians, authors etc. (Barnhart 56). Depending on the editor and on what kind of dictionary a coinage should enter, one factor might be more of a value than another. Of the many thousands new words created each year, about 200 new words fulfill the above-mentioned conditions and make their way into a standard dictionary. Authors, TV, radio and news reporters use these new terms on a large scale, and thus they become vogue words for a certain period of time or even forever (Barnhart 56). But then the struggle of a new word is not over yet. If it is not used anymore or lost its importance, it will be deleted in the end (Sheidlower 38). Practical considerations play their part in the march of a word into a dictionary. Chief among these is the scope of the dictionary and its physical limitations. Because general lexicography is a commercial art form, dictionaries reflect the judgment of their makers and the needs of their publishers. Consequently, no dictionary is complete. There is a considerable difference between general dictionaries and Among the New Words. The dictionaries aim is to supplement the existing English vocabulary, whereas Among the New Words aims to chronicle the development of the English language (Barnhart 59). For this reason, these criteria stated above (2.4.1 to 2.4.4) hardly apply to Among the New Words.

Human Life :: essays research papers

The beliefs and views of modern society are hypocritical and unjust. By the time an individual matures from a young child to an adult, they have been taught an uncountable number of life lessons. One of the outstanding lessons that each and every person has learned is that killing another human being is wrong. This is perhaps the first recognizable lesson on the value of human life. Most children know that killing is against the law and learn religiously that it goes against all religious morals and beliefs, yet society is bombarded by violence everyday in the media and in real life. Today, the value of human life can be questioned, especially that of the young. Through numerous examples of child murder and abortion it is rather obvious that the lives of the unborn or newly born are not valued to the degree that they should be. In most cases, the young are not recognized as "people" and are robbed of their human rights and freedoms. Young lives, both born and unborn, are s een as more of a commodity these days, than as precious, magical miracles. In the media today there are ridiculous numbers of reports pertaining to accidents, shootings and robberies-these are just a few examples of unjust acts that are occurring everyday. There is also a shocking amount of coverage about parents accidentally, or on the other hand, brutally murdering their kids. Parents are supposed to be loving and supporting caregivers, they have a great influence over everything a child can possibly say or do. It is hard to believe that some parents would actually take their children’s lives into their hands. Recently in the news there have been accounts of a mother poisoning her son to a father taking a knife and slashing his son’s throat. These are all cases where the parent in charge has taken advantage of their control. Each helpless child is defenseless in these situations. In many cases, children have become victims of a parent’s mental instability. In one case a mother claims to have been "suffering form delusions about h ell when she took the life of her twenty month old child." In the end this woman was found not criminally responsible because "she had apparently been suffering from psychosis the day of the drowning." She was then committed to a psychiatric hospital. This seems to be common place today, and there is no justice done for the young slain victims.

Power of Communication Essay

Communication is the basic human need to share meanings and express ideas and thoughts and that can be achieved by the exchange of information between the society members. The process of communication is defined by the technology available, culture and protocols of communication. Political scientists are interested in political communication through studying the interaction communication between the political system and the political process generally and they confirmed the importance of the fundamental relationship between them, they called for re-examination and analysis of political science based on communication theories. Politics is difficult to be found without communication because there must be a link between the public and the ruling elite (decision makers), and this applies to the political system too. Citizens must be able to communicate their wishes and demands to the government, and the government should be able to communicate its decisions to citizens and justify them to win their satisfaction. Political parties and politicians needs huge public support, Where it can be said that political communication is the most important means of communication that must be followed by a party in order to gain such support. It is well known that the objective of any party is to access power or participate in it and this cannot be reached without large public support. This political communication can take various forms depends on the technology available such as press, radio, television and digital networked media. The political communication is the proper way of any party members to open dialogue with the masses of the people for establish the doctrine of their party to them, and gain popular support for the policy and programs of the party, where they listen to note of the public towards some situations and impressions towards it, and the members of the party again, during their partisan meetings to discuss the various social and economic problems in the community, and that need solutions, ranging proposals of different party members to fixing these problems through the hierarchical organization of the party until it reaches the level of leadership and integrate in the various party programs. thereby ensuring this party kind of interaction with he public surrounding it, so that lead the response to the wishes and requirements of the public in the general policy of the party, to achieve a great deal of compatibility between the party and street folk, and this goes back to the party with a grea t benefit in elections times, When the public find the investigator to them ambitions and expectations, and This causes at normal conditions for arrival (the party with compatibility larger with the popular will) to rule the country. Communication was and will continue to be the most important activity in human life through interacts with others to express ideas, needs and feelings and dreams, and has expressed their personality, culture and freedom and the idea of an activity that can be embodied the meaning of human dignity and values. So this make this activity one of the most activities accountable of various standards, pressures and the laws that are on the whole a fundamental question about the nature of the relationship between the media and the ethics and other aspects of human life. Communication science benefited and interact with all the of Sciences and knowledge, humanitarian, technical data and the science explain to us at this time to what affect the means of mass communication in the minds of the people and what is the size of this effect and how it is affecting. No one can deny the importance of these theories of communication that formed the communication science which had experimented in communities that adopted and tried to apply. The communication tools play an important role in political life, whether internal or the outside, not only political professionals are attach importance to their communication strategy, but governed also gaining most of their information through the communication tools. The means of mass communication possesses the characteristics and capabilities of multiple distinct from those when its counterparts from groups or opinion leaders, are in any case means mass communication addresses the daily huge cross sections of the population with one voice. The means of communication and media are necessary and important to make effectively communication links and interactions are always open between the ruler and the governed. Definitely, mass communication has evolved technically accompanied by the technological development happened to human societies in all fields, in ancient societies (Greek and Roman society), political community was limited and number of citizens who can be covered by ruling messages was known, so it was direct speeches and forums in public places established in open air r in the theaters of the city that was one of the most forms of political communication, so it was politicians highly dependent on rhetoric and the ability to inference to convince they governed, This free space for debate and political communication that helped to create direct democracy known as the Athenian democracy, But with the development of human societies and the expansion of political activity field appearance regimes of modern political became not possible to rely solely on speeches and seminars, which includes a limited number of citizens, but became necessary to find a communication to spread and includes a wide segment of the public. (Karl W. Deutsch, 2006) Literature Review: Denis McQuail, 2010 â€Å"Seen these arguments written, visual and audio as a tool of direct democracy, and as a court of public opinion open day and night put the law for everything all the time, not a substitute for institutions, but such ray of light detector that keeps moving here and there, revealing always talking about the depths of darkness† Jacques Gerstle, 2004 â€Å"One of the basic properties of the twentieth century is the communication tools revolution, and the appearance the community of communication. We saw the appearance of new techniques for political communication, these techniques that contributed in dissemination and sharing the information, ideas and communities in conditions limited time and across a wide geographical. † Since the advent of printing, which contributed historically in the advancement of the theory and practice of democracy through journalism written is the court of public opinion, as well as with the emergence of radio, which was the most important means of communication used in the second world war propaganda by politicians, through well television, which affects more than other means of mass communication. Various categories divergent public and geographically, does not follow some of the obstacles faced by other means such as the written press such as distribution problems and an individual’s ability to read all the way to satellites to broadcast dimensional networks of electronic communication global movement of information and ideas and comply with the limits of regional and geographical, with the development of all these means and which was called some people name new technologies for information and communication find that the process of political communication has evolved is also no longer this process takes place using the means of communication like a traditional speech, for example. Gabriel A. Almond, 2004 â€Å"That everything in politics is communication, system of communication is one of the main channels for the flow of information from the elite to the masses and also to transfer the problems of the masses and their aspirations and their perceptions to the elite. † Robert Wiener, David Jerison, I. Isadore Manuel Singer, Daniel W.  Strook, 1997 â€Å"If we realized politics is system so communication system is the nerve that controls the system, and the system’s ability to exercise command and control linked to its ability to deal with the information, so that communication and control are two synonymous of same meaning, every time we call we also control. † Karl W.

PALEOLITHIC VS NEOLITHIC ART essays

PALEOLITHIC VS NEOLITHIC ART essays The following is a comparison of art from the Paleolithic and Neolithic periods in history. Paleolithic Art is art that was produced about 32,000 to 11,000 years ago. The art of the Paleolithic period falls into two main categories: portable pieces, such as small figurines or decorated objects, and cave art. Paleolithic art usually is classified as either figurative that is, depicting animals or humans, or nonfigurative, taking the form of signs and symbols. The portable art of the Paleolithic period was carved out of bone, antler, or stone, or modeled in clay. They consist of carefully worked small flint figurines of people, animals and birds, which are schematic and stylized and were probably used as amulets. This art has been found in much of Europe, in Northern Africa, and in Siberia. Paleolithic cave art, discovered in the 1860s by French paleontologist Edouard Lartet, primarily in northern Spain and southern France, takes the form of paintings, drawings, and engravings on cave walls. Artistic objects made during the Paleolithic era occupy an important place in history, since this is the only source from which we can reconstruct and study people of ancient times. The meaning and purpose of such objects from the Paleolithic era are usually identified with ancient cults. Neolithic Art is the art and architecture of the prehistoric period stretching roughly from 7000 to 3000 BC. Neolithic art was primarily composed of pottery and architecture. By the Neolithic age the advances in technology such as farming, weaving, the advent of pottery and the construction of monumental structures such as Stonehenge, indicate that humankind begin to settle and develop their land. Neolithic people created wooden figurines of people and animals along with pottery decorated with triangles, spirals, wavy lines, and other geometric forms on its rough or polished surfaces. There are a number of articles intended for tr ...

Where to Get the Money to Write a Book

Where to Get the Money to Write a Book This is the most common request I receive. Where can I find the money to write my book? This is the second most common request I receive. Where can I find the money to publish my book? First and foremost, you do not need money to write a book. Writing is the most liberating, free-rein, no start-up money required art on the planet. You and the paper. If you need research, you have a phone, the Internet and the library. Easy-peasy. If you need money to publish your book, you are self-publishing. Fine. Nothing wrong with that. Lets make some assumptions here. You wrote the story. Youve edited the story. Youve HAD the story edited. You want that book out in the world and you dont have two dimes to rub together. What do you do? 1. You try to traditionally publish. Yep, this means you have to learn the publishing business. But you want complete control over your book, you say. Do you even know what that means? Can you talk traditional vs. self-pubbing? If you cannot, then stop trying to publish. Learn which road to take before get totally lost and ruin that story 2. You publish an e-book. I know you want to hold paper in your hands, but why not sell e-books until you have the money saved to pay for print? 3. You publish through CreateSpace.com or Lulu.com. This requires you understand formatting, cover design, and so on. If you want someone to publish your book without you thinking about these things, then go back to Item 1. 4. You crowdfund through Kickstarter.com or Indiegogo.com. Not only has Kickstarter funded many books, plays and films, but it makes you develop a defined plan for your book project. Most crowdfunding projects fail because the author doesnt want to think marketing or development . . . doesnt plan deeply enough. Either that or the book is a bad idea to start with. 5. You freelance and save your money from articles and gigs to pay for the publishing. No elaboration needed here. If you think youre good enough to write a book, you should be shrewd and talented enough to make money freelancing. 6. You save money from other sources. Only you can define your other sources. 7. You borrow the money. Gasp! Borrow? What if the book fails? Truth is you need to believe in this book hard enough to be willing to borrow money for it. That means youre more likely to do your homework on the process, edit a few more times, create the start of a platform, and design a short-term and long-term plan. What about grants? Grants should be your last resort. Besides, most grants wont fund a self-published project, especially from a first-time author or a second-timer who didnt sell the first. You have to prove yourself to a certain degree. But hey, with all of the above options and a little bit of elbow grease and sweat, youll be published in no time.

Temperature Definition in Science

Temperature Definition in Science Temperature is an objective measurement of how hot or cold an object is. It can be measured with a thermometer or a calorimeter. It is a means of determining the internal energy contained within a given system. Because humans easily perceive the amount of heat and cold within an area, it is understandable that temperature is a feature of reality that we have a fairly intuitive grasp on. Consider that many of us have our first interaction with a thermometer in the context of medicine, when a doctor (or our parent) uses one to discern our temperature, as part of diagnosing an illness. Indeed, temperature is a critical concept in a wide variety of scientific disciplines, not just medicine. Heat Versus Temperature Temperature is different from heat, although the two concepts are linked. Temperature is a measure of the internal energy of a system, while heat is a measure of how energy is transferred from one system (or body) to another, or, how temperatures in one system are raised or lowered by interaction with another. This is roughly described by the kinetic theory, at least for gases and fluids. The kinetic theory explains that the greater the amount of heat is absorbed into a material, the more rapidly the atoms within that material begin to move, and, the faster atoms move, the more the temperature increases. As atoms begin to slow down their movement, the material becomes cooler. Things get a little more complicated for solids, of course, but thats the basic idea. Temperature Scales Several temperature scales exist. In the United States, the Fahrenheit temperature is most commonly used, though the International System of Units (SI unit) Centigrade (or Celsius) is used in most of the rest of the world. The Kelvin scale is used often in physics and is adjusted so that 0 degrees Kelvin is equal to absolute zero, which is, in theory, the coldest possible temperature and at which point all kinetic motion ceases. Measuring Temperature A traditional thermometer measures temperature by containing a fluid that expands at a known rate as it gets hotter and contracts as it gets cooler. As the temperature changes, the liquid within a contained tube moves along a scale on the device. As with much of modern science, we can look back to the ancients for the origins of the ideas about how to measure temperature back to the ancients. In the first century CE, the Greek philosopher and mathematician Hero (or Heron) of Alexandria (10–70 CE) wrote in his work Pneumatics about the relationship between temperature and the expansion of air. After the Gutenberg Press was invented, Heros book was published in Europe in 1575, its wider availability inspiring the creation of the earliest thermometers throughout the following century. Inventing the Thermometer The Italian astronomer Galileo  (1564–1642) was one of the first scientists recorded to have actually used a device that measured temperature, though it is unclear whether he actually built it himself or acquired the idea from someone else. He used a device called a thermoscope to measure the amount of heat and cold, at least as early as 1603. Throughout the 1600s, various scientists tried to create thermometers that measured temperature by a change of pressure within a contained measurement device. English physician Robert Fludd (1574–1637) built a thermoscope in 1638 that had a temperature scale built into the physical structure of the device, resulting in the first thermometer. Without any centralized system of measurement, each of these scientists developed their own measurement scales, and none of them really caught on until Dutch-German-Polish physicist and inventor  Daniel Gabriel Fahrenheit (1686–1736) built his in the early 1700s. He built a thermometer with alcohol in 1709, but it was really his mercury-based thermometer of 1714 that became the gold standard of temperature measurement. Edited by Anne Marie Helmenstine, Ph.D.

Protection Provided to Employees in the Public Services Essay

Protection Provided to Employees in the Public Services - Essay Example Sex Discrimination Act, 1975 is applied to both men and women, which makes sex discrimination in employment, vocational training, education, the provision and sales goods, facilities and services as well as premises, unlawful. To clarify Great British law which is related to gender reassignment the Sex Discrimination (Gender Reassignment) regulations 1999 was enacted. It is a measure in order to prevent discrimination against transsexual people on the grounds of sex in pay and treatment in employment as well as vocational training. In April 2007, Gender Equality Duty came into force and it is the biggest change in sex equality legislation in thirty years since the Sex Discrimination Act was introduced. In recognition of the need for a radical new approach to equality, it was introduced, which placed service providers the responsibility to think strategically about gender equality, rather than living it to the individuals to challenge poor practice. For Employers, Equal Pay Act 1970 makes it unlawful to discriminate between men and women in terms of their pay as well as conditions where they are doing similar work, work rated as equivalent, or work of equal value. It is applied to both men and women however it does not give everyone the right to claim equal pay with a person of the same sex. That is, in other words, any comparison must be with a person of the opposite sex. In 2003, the act was amended (Sheard, A., 2006d). Based on Race Race Relations Act, 1976, makes it unlawful to treat a person less favourable than the others on the grounds of race. This includes protection of people against racial discrimination the grounds of race, colour, nationality (citizenship), as well as national or ethnic origin, in the fields of employment, education, training, housing, and the provision of goods, facilities as well as services. In order to eliminate institutional racism and prohibit racial discrimination in all public functions with only a few exceptions and give a new statutory duty to promote race equality, Race Relations (Amendment) Act 2000 was enacted. Its aims are to provide fair and accessible services as well as improve equal opportunities in employment. The general duty of this Act is to eliminate unlawful racial discrimination, to promote equal opportunities as well as to promote good relations between people from the different racial group; and under these duties, public authorities must prepare and publish a Race Equality Scheme which should explain how general, as well as specific duties, will be met.     Ã‚  

International Business Strategy Essay Example | Topics and Well Written Essays - 1750 words

International Business Strategy - Essay Example It is a fashion house established by Thomas Burberry in 1856, which became iconic for its check pattern and its outdoor line of clothing, particularly its trench coats. Its long years of existence and ties with the British historical narrative since the 1900s, established Burberry as a heritage brand. At present, it is a holder of Royal Warrants, which is a form of recognition that the establishment provides goods to a member or members of the royal family. These variables are inherent in Burberry’s branding and figure prominently in its competitive strategies. But during the 1980s, the company has experienced poor performance and this persisted way until the latter part of the 1990s. This changed in the past decade and the company is considered to be one of the best global brands in its category and is operating with record profit. Currently, Burberry has more than 500 stores in over 50 countries. This report will explore Burberry’s strategies, which allowed it to gain competitive advantage in the luxury market and achieve successful expansion overseas. The Luxury Fashion Market: An Analysis The luxury fashion market is composed of several categories but these are mostly dominated by apparel and footwear. It can also include leather goods, accessories and jewelries. While each of these can very well be considered a separate industry, companies tend to sell them all given the fact that they do overlap, mainly because they have the same consumer demographics and consumer demand profile. The fashion luxury industry – mature industry - caters to a specific group of consumers: the wealthy. These are those who need practical (since clothing and footwear are, of course, necessities) but prestigious products; and those who are fashion conscious. This variable explains why the industry emphasizes intensive marketing and advertising campaigns. The consumer demographics and demand profile, wrote Wagle (2003), also underpins how the overall industry d emand is driven by â€Å"general economic trends, including changes in disposable personal income, consumer confidence, and consumer spending.† What this means is that in times of economic growth, the market’s demand is driven by the consumers’ need and impulse, whereas, during economic downturn, caution permeates the market. This is demonstrated in the poor performance of luxury fashion companies during the recent financial crises. The financial crunch, based on several empirical evidences, is proven to put pressure on the luxury market. The Global Economic Crisis Resource (2009, p.27), for instance, stated in one of its findings that â€Å"much activity in the luxury market has been driven by easy credit and perceived wealth† and that the crisis has significantly reduced the net worth of the rich, forcing them to cut consumption significantly. Today, the luxury fashion industry is a lucrative business due to globalization. The robust development of emer ging economies such as China, India, Russia, and other countries, has led to an expanded demand for luxury goods. In addition, it also provided the opportunity to source cheaper materials and labor abroad. The integration of the international market has facilitated these trends and companies like Chanel, Gucci, Hermes, Louis Vuitton and Burberry effectively seized the opportunity to their advantage. However, it also increased competition and changed the dynamics by which products are made and sold to consumers. Competition As previously

Media, Identity and the Popular Essay Example | Topics and Well Written Essays - 3000 words

Media, Identity and the Popular - Essay Example Given the power, extent, and outreach of popular media – including films and television, the social construction of characters belonging to racial and ethnic minorities are bound to have a significant impact on the wider audience (Downing & Husband, 2005). Signorielli (2001) described television as "the nation’s primary story-teller" (p. 36) engaged in the role of continuously 'feeding' its audience with healthy doses of what can be construed as 'mainstream' views (Gerbner et al., 2002). The representation of racial and ethnic minorities in films and television, hence, is a critical subject of analysis and needs to be explored because the sheer extent of media outreach and the number of ardent viewers these forms of popular media attract almost ensure a greater social impact over a period of time (Mastro & Greenberg, 2000). This essay aims to highlight, explore, and analyse the manner in which these popular mediums of communication particularly films and television port ray racially and ethnically diverse characters; the gradual shift in such portrayals over time; followed by the influence and impact of the same supported by theoretical implications of such representation. The examples discussed as a part of the study include popular films and television shows from the UK, U.S., and Canada. Media representation of racial / ethnic minorities: An Overview Hall (1981) stated that media as a key tool of propagating ideologies often uses the platform to generate representations of the socio-cultural environment around us by way of images and characters. These characters in turn accentuate the understanding of its audience with regard to the manner in which the world around is and influence them to interpret the messages coded therein with regard to the members of the racial and ethnic minorities. The persistent portrayal of such images leads such characters and / or images to become naturalized enabling the viewers to understand these images and charact ers in the way they are portrayed (p. 11). Cultural theorists focused on investigating cultural and racial representations in popular media have identified the portrayal of 'whiteness' as the dominant theme and as a strategic rhetoric. The images and characters associated with the dominant white population are often indicative of their privileged status in both films as well as on prime time television shows and /or soap operas. It is also often argued that 'whiteness' is often the most dominant and overarching norm against which all other races are measured and compared (Ott, 2010: p. 139). African-Americans have consistently been under-represented as compared to their white counterparts in films and television programs in the United States (Wilson, 1996; Dixon & Rosenbaum, 2004). Although there has been a commendable and dramatic change in trend with regard to portrayal of racial and ethnic minorities on television shows and films over the years, the blacks continue to be either u nder-represented or portrayed in characters / roles that tend to perpetuate and even increase stereotyping (Dill, 2013: p. 253). Most of the popular television shows aired during the previous decade often included Caucasians as key protagonists with supporting

Data Protection and Future Changes in Healthcare Informatics Research Paper

Data Protection and Future Changes in Healthcare Informatics - Research Paper Example Information Technology has modified the healthcare sector to enhance efficiency, quality and safety. The contribution of information technology in healthcare is relatively low. However, there are indications via surveys that investors are gearing up for increasing their investments. Although, a major barrier for healthcare systems includes the cost and complex implementation that may triggers significant work and cultural modifications. Moreover, the input for healthcare systems consists of Electronic Health Records (EHR). These records represent life history for patient’s health information produced by one or more encounters in any care delivery systems. Moreover, the electronic health facilitates doctors to extract medical life history at a glance, resulting in improved and fast response to medical treatment and medication for the patient. Information technology facilitate healthcare with instant access to rich information related to patients, on the other hand, protection o f these electronic health records is utmost important. Likewise, mismanagement of electronic health records can cause delay in treating a patient who needs urgent medication. Moreover, mismanagement of records can split records with one another resulting in wrong treatment of the patient. Furthermore, one more scenario includes a patient in an intensive care unit, where the doctor cannot find electronic health record due to some system failure. For countering these issues, data protection requirements and standards must be defined. Electronic health Records and Data Protection As discussed, electronic health architecture represents life history of a patient’s medical history. In fact, it is an electronic version of the patient’s medical history and is updated by health care professionals as required. The electronic version also includes, all the primary administrative clinical data, pertinent to that patient’s care under a particular health care professional. In addition, the electronic health record includes demographics, progress notes, issues, vital signs, medications, immunizations, test reports, laboratory data and radiology reports (Overview electronic health records). Moreover, a comprehensive idea related to its architectural requirements is available on ‘www.openehr.org’ stated as â€Å"a set of clinical and technical requirements for a record architecture that supports using, sharing, and exchanging electronic health records across different health sectors, different countries, and different models of healthcare delivery†. The definition represents the flow of these health records across the different geographical locations within the computerized network. As the information flows on the network, there is always a probability related to security and data protection of these health records. Moreover, the program named as Advanced Informatics in Medicine (AIM) highlighted severe safety problems. Furthermore, the group was created for addressing the issues on the basis of Six Safety First Principles for medical informatics. Consequently, the findings were remarkable as previously no issues were highlighted with prime concerns (Lacoste,). For instance, the issues involve giving the wrong treatment to the patients, refuse to give the appropriate treatment, delay the treatment due to insufficient information etc. These issues are of prime concern, as they can result in premature

Water resource issues Essay Example | Topics and Well Written Essays - 250 words - 1

Water resource issues - Essay Example Population size is increasing day by day whereas the availability of fresh water remains stationary or decreasing. As a result of that, the available fresh water per head is getting reduced as time goes on. Drinking water is an essential commodity required to sustain human life on earth. It is believed that the next world war may be occurred probably for the control of fresh water resources. Many people believe that the recent attack on Iraq by America was not to take revenge upon Saddam, but to seize control over the fresh water resources of Iraq. In any case, drinking water shortage is getting intensified as time goes on. It is necessary to manage water resources judiciously to overcome the drinking water shortage. Strategies necessary to reduce the pollution of fresh water resources should be implemented as much as possible. The usage of fertilizers and chemicals should be reduced as much as possible and organic farming methods should be employed more and more. Industrialization should be done carefully and the industrial wastes should not be allowed to mix with fresh water resources. In short, a little bit control on industrialization and farming would reduce the water pollution

Fiji's relative global economic development Essay

Fiji's relative global economic development - Essay Example Till the 1980s, the descendants of Indian laborers that the British had brought on the islands dominated the country. Since 1987, the islands have faced a number of military coups that have disrupted attempts to form a democracy. The 1990 constitution of Fiji strengthened the powers of the native Melanesian community over the political scenario although an amendment in 1997 gave equal powers to the Indians and the natives. However, political turmoil has continued in the islands resulting in disturbances in the economic activities of the population and trade relations with the rest of the world (CIA). Fiji had an estimated population of 918,675 in 2007, of which 30.9 percent is below 15 years of age, 64.7 percent between 15 and 64 years and 4.4 percent above 64 years (CIA). 54.8 percent of the population are native Fijians, mostly Melanesian and Polynesian mix, 37.4 percent Indians and the remaining 7.9 percent others comprising of Europeans, other Pacific islanders and Chinese. About 92 percent of the Fijian population is literate (Bank of Hawaii, 1998). Fiji is richly endowed with natural resources, with forest, fish and mineral assets and is among the most developed among the Pacific Ocean islands. Yet, the economy of Fiji is still dependent on revenues from sugar export, tourism and remittances from Fijians abroad. 8.9 percent of Fiji's GDP of $2.033 billion in 2007 was accounted for by agriculture, 13.5 percent by industry and 77.6 percent by services, mostly tourism. One third of Fiji's industrial activity is related to sugar but processing of sugar is inefficient. Fiji exports most of the sugar output to Europe and may be hit by proposed subsidy cuts on sugar by the European Union. Tourism has also been affected by the repeated coups in the country. The Reserve Bank of Fiji anticipated a contraction of the economy by 3.1 percent in 2007-08 (CIA) and a runaway current account deficit, which was 23 percent of GDP in 2006. Relative Economic Development and Concerns Fiji ranks 92nd in the Human Development Index (HDI) and in terms of per capita Gross Domestic Product at Purchasing Power Parity, with $6,049 and 108th in terms of life expectancy at birth, which is 68 years (HDR). In 1998, Fiji ranked top of the World Bank's list of lower-middle income group countries and was in the same category as Latvia, Peru, Lebanon and Costa Rica (Bank of Hawaii, 1998). However, political instability and lack of industrial activity have resulted in some contraction of the economy since then. Fiji is a small country, slightly smaller than New Jersey. The economy is also far smaller than the United States. The per capita GDP at official rates in Fiji in 2007 was $4,100, less than one-tenth of what it was in the US, at $46,000. Life expectancy at birth in Fiji, at 68 years, was also lower than in the US, 78 years. Population below the poverty line in Fiji in the last estimated year, 1990-91 was 25.5 percent and the unemployment rate was 7.6 percent. On the other hand, only 12.4 percent of the population in the US was below the poverty line in 2004 and the unemployment rate in 2007 was 4.6 percent. Fiji exports primary products, mostly agricultural to the US and Europe, and imports manufactured commodities. The major concern for the Fijian economy is the political uncertainty that the islands have been facing over the last two decades. This has resulted in

The recall had several implications that include decline in stock price and stock volume. However, the company implemented some risk practices and recommendations since the company seem not to have had enough measures to rectify the mass recall. Other associated risks emerged such as strategic risks, supply chain risks, hazard risks as well as financial risks. In this case, it was the responsibility of the executive team to realign the company’s management structure through implementation of significant recommendations capable of rectifying the previous mistakes. There were also recommendations that were geared towards building of corporate stakeholder relationships. Therefore, this study seeks to identify the different pure risks that transpired at GM Company in the last five years, the effects and the general solutions that were put in place to rectify the mistakes suffered by the

Vehicle ad-hoc Network (VANETS) Technology

Vehicle ad-hoc Network (VANETS) Technology Chapter 1 Introduction Now a day, everything is moving away from wired technology and leading towards wireless. The fascination of mobility, accessibility and flexibility makes wireless technologies the dominant method of transferring all sorts of information. Satellite televisions, cellular phones and wireless Internet are well-known applications of wireless technologies. This work presents a promising wireless application and introduces a tiny contribution to its research community. Research in wireless communication field is growing faster, day by day, then any other field. It serves a very broad range or series of different kind of applications using different topologies. Every one of these comes with some new and specialized protocols. In this research, we will present an introduction to a wireless technology. This wireless technology directly affects car accidents and the sales of one of the largest markets. It is the technology of building a strong network between mobile vehicles; i.e. let vehicles communicate to each other. This promising technology is literally called Vehicular Ad-Hoc Networks (VANETs). 1.1 Background Since the first invention of mobile vehicles, governments and manufacturers have researched accidents to reduce the number of vehicle crashes in order to reduce costs, injuries and fatalities. First of all, VANET technology is going to reduce crashes by doing research in this field. Accordingly, related governmental authorities initiated new projects to the learning institute for study, research, development in the field of wireless technology and VANETs also paying attention in its standards. The ‘Dedicated Short Range Communications (DSRC) [1] is a pioneer ITS (Intelligent Transportation Systems which is a branch of the U.S. Department of Transportation [2]) project dedicated to VANET standardization. Then, the acronym or short form ‘DSRC becomes a global or familiar name of kind of standards that aim to put VANET technology into life. The DSRC mainly concerns with the communication that is how to make different communication links between vehicle-to-vehicle and vehicle -to/from-roadside units. 1.2 Motivation In the last few years, vehicular network has gained great attention in industry. Federal communication commission (FCC) has assigned 5.850-5.925GHZ frequency band to promote safe and efficient road trips, which is planned for vehicle-to-vehicle and vehicle-to-infrastructure communication. Car manufacturers, e.g., Audi, BMW and DaimlerChrysler, also formed a Car2Car communication consortium [3], in which the prototype development for inter-vehicle communications is underway. In near past, IEEE 802.11-based solutions for VANETs are also studied by IEEE 802.11p. IEEE 802.11p Wireless Access in the Vehicular Environment (WAVE) that defines changes to IEEE 802.11 to help Intelligent Transportation Systems (ITS) applications. IEEE 802.11p helps data exchanges between fast moving vehicles with each other and also exchanges data from vehicles to road side unit or from road side unit to vehicles in the licensed ITS band of 5.9 GHz. The Dedicated Short-Range Communications (DSRC) at 5.9 GHz is here today to provide safety that is increasing safety in case of road accidents, reducing highway or road maintenance cost and also improving mobility. Intersection and road departure collisions report for round about 50 percent of all crashes and victims on our roads. On an average day in the United States, vehicular collisions kill 116 and injure 7900[8]. More health care dollars are consumed in the United States treating crash victims than any other cause of illness or injury [8], [10]; the situation in the European Union is similar, with over 100 deaths and 4600 injuries daily, and the annual cost of â‚ ¬160 billion [11]. By getting rid from road victims and crashes, DSRC can provide or play important role in reducing road accidents, deaths, injuries, heavy traffic and increasing road safety by improving communication between vehicles and between vehicles and road side infrastructure. DSRC emerged from a partnership among automobile manufacturers, state and federal transportation officials, toll transponder equipment suppliers and the Federal Communications Commission. There is a recognized need for on-the-go communication with motor vehicles and reliable communication between vehicles to increase highway safety by providing warnings and alerts that enable drivers to take corrective and/or evasive actions. At the same time, it can be able to provide information i.e. real time information to drivers so that to improve mobility and motorist conv enience, such as information on congestion or traffic incidents. The car manufacturing industrys determination to roll out vehicle-to-vehicle communication in the near future and, on the other hand, to the increasing disillusionment concerning the need for the vast number of protocols developed for general Mobile Ad-Hoc Networks (MANETs) in the past few years while on the other side that is for VANETs, industry pressure has created a situation in which an overwhelming interest in solutions to problems leads to a preference for real-world research as opposed to fancy theory. As the concept came from MANETs which totally depend on the subscribers motion as the motion is random it is difficult to cater it but this problem was very negligible when researchers observed it in VANETS. At highways vehicle move in an organized pattern with different speeds so initially it seemed that VANET will easily be implemented. Another major reason for VANET can be Traffic deaths and injuries which is a major health and social issue. While industrialized nations (e.g., the United States) have continuously reduced annual traffic deaths since 1970, annual traffic-related fatalities and injuries remain high (in the United States alone there were over 41,000 deaths and 5 million injuries in 2000, according to the NHTSA) [7]. The economic impact of vehicle crashes in the United States exceeded US$230 billion or 2.3 percent of the U.S. GDP in 2000 [7]. We want to remain connected with the world through net whether at home, airport, at work or even on the roads.

Intersection/Hidden Driveway Collision Warning vehicles communicates to avoid collisions at intersections without traffic lights or hidden driveway. Roadway Condition Awareness Vehicles communicates to extend vision beyond line of sight (e.g. beyond a big turn or over a hill) Table-1.1: Example of Vehicle Safety Communication [10] 1.3 Scope of Project Some of the industries and universities working on VANETs are as follow DaimlerChrysler AG Fraunhofer FOKUS NEC Europe Ltd. Robert Bosch GmbH Siemens AG TEMIC Telefunken Microelectronic GmbH Universities of Mannheim, Hamburg-Harburg, Karlsruhe, and Hannover. 1.4 Organization of Project Thisthesisis mainly divided into four chapters. In the first two chapters (1-2) introduction and an overview over the topic and used technologies is given. In the following chapter (3), we have discussed the standards of IEEE and also discussed the MAC Layer and PHY Layer of IEEE 802.11 in detail. In chapter 4, simulation analysis of our work is shown along with the results. In the last chapter, we have summarized this whole thesis, what we have concluded from this project and future work needs to be done are discussed. Finally, in appendix some additional information can be found. In chapter two, VANETs characteristics, some of its applications and the research challenges faced by governments and car manufactures are discussed, continued by MAC Layer and PHY in chapter three. We have also discussed the WAVE architecture in chapter 2. From chapter three on, we have a look at some protocol improvements and extensions. Some thoughts, tests and their results on VANETs, those are related to our work, can be found in chapter 4. Chapter 2 VANETs VANETs (Vehicle ad-hoc Networks) is a form of Mobile Ad-hoc Networks (MANETs), which provide a communication between the vehicles and also fixed equipments, usually defined as road side equipments. 2.1 What is VANET Vehicle ad hoc network comprises of three words. i. Vehicle ii. Ad-hoc iii. Networks i. Vehicle â€Å"A machine such as a bus or car for transporting people or goods†. [4] A lot of progress is happening in the field of vehicles since the invention of wheel. Development is due to provide services to the people and make their task easier. ii. Ad-hoc It refers to dealing with special situations as they occur rather than functions that are repeated on a regular basis. For example you just meet someone outside your office and you exchange some words. On the other hand infrastructure system is a system which is fully installed and deployed than it works according to some predefined rules and regulations. iii. Network â€Å"A system, as in a business or university, consisting of a computer or computers and connected terminals, printers etc. specific, a local area network†.[3] The concept of networking is introduced because resources are limited and we have to utilize them efficiently. As it is not possible for firms to provide printer, faxes and other machines to everyone so they just inter linked all the devices so that each one can utilize it keeping the cost at minimum. Vehicular connectivity can be fairly considered a future killer application, adding extra value to the car industry and operators services. Taking into account the constant growth of automotive market and the increasing demand for the car safety, also driven by regulatory (governmental) domain, the potential of car-to-car connectivity is immense. Such system should be suitable for a wide spectrum of applications, including safety related, traffic and fleet control and entertainment. First, issues concerning architecture, security, routing, performance or QoS need to be investigated. Standardization of interfaces and protocols should be carefully planned to ensure interoperability, as vehicles coming from different vendors must communicate seamlessly. Having different competing systems would result in decreased market penetration and poor overall system efficiency, thus only one common system can be deployed. And finally, wise deployment strategy has to be proposed, as most applicatio n would become functional only after certain market penetration is reached. The first milestone of standardization process was the allocation of 75 MHz of DSRC (Dedicated Short Range Communications) spectrum to accommodate Vehicle-to-Vehicle (V2V) and Vehicle-to- Infrastructure (V2I) communication for safety-related applications by US Federal Communications Commission (1999). Commercial applications are also allowed to operate in this spectrum. 2.2 VANETs Applications According to the DSRC, there are over one hundred recommended applications of VANETs. These applications are of two categories, safety and non-safety related application. Moreover, they can be categorized into OBU-to-OBU or OBU-to-RSU applications. Some of these applications are as followed: 2.2.1 Co-operative Collision Warning Co-operative collision warning is an OBU-to-OBU safety application, that is, in case of any abrupt change in speed or driving direction, the vehicle is considered abnormal and broadcasts a warning message to warn all of the following vehicles of the probable danger. This application requires an efficient broadcasting algorithm with a very small latency. 2.2.2 Lane Change Warning Lane-change warning is an OBU-to-OBU safety application, that is, a vehicle driver can warn other vehicles of his intention to change the traveling lane and to book an empty room in the approaching lane. Again, this application depends on broadcasting. 2.2.3 Intersection Collision Warning Intersection collision warning is an OBU-to-RSU safety application. At intersections, a centralized node warns approaching vehicles of possible accidents and assists them determining the suitable approaching speed. This application uses only broadcast messages. In June 2007, General Motors ‘GM addressed the previously mentioned applications and announced for the first wireless automated collision avoidance system using vehicle-to-vehicle communication (Figure-2.1), as quoted from GM, If the driver doesnt respond to the alerts, the vehicle can bring itself to a safe stop by avoiding a collision. 2.2.4 Approaching Emergency vehicle Approaching emergency vehicle is an OBU-to-OBU public-safety application, that is, high-speed emergency vehicles (ambulance or police car) can warn other vehicles to clear their lane. Again, this application depends on broadcasting. 2.2.5 Rollover Warning Rollover warning is an OBU-to-RSU safety application. A RSU localized at critical curves can broadcast information about curve angle and road condition, so that, approaching vehicles can determine the maximum possible approaching speed before rollover. 2.2.6 Work Zone Warning Work zone warning is an OBU-to-RSU safety application. A RSU is mounted in work zones to warn incoming vehicles of the probable danger and warn them to decrease the speed and change the driving lane. 2.2.7 Near Term [5] Traffic Signal Violation Warning Curve Speed Warning Emergency Electronic Brake Lights 2.2.8 Mid Term [5] Pre-Crash Warning Cooperative Forward Collision Warning Left Turn Assistant Lane Change Warning Stop Sign Movement Assistance Application Comm. type Freq Latency Data Transmitted Range Traffic Signal Violation 12V One-way, P2M 10 Hz 100msec Signal Status, Timing, Surface Heading, Light Position, Weather 250m Curve Speed Warning 12V One-way, P2M 1 Hz 1000msec Curve Location, Curvature, Speed Limit, Bank, Surface 200m Emergency Brake Light Vehicle to Vehicle Two-way, P2M 10 Hz 100msec Position, Deceleration Heading, Velocity 200m Pre-Crash Sensing Vehicle to Vehicle Two-way, P2P 50 Hz 20msec Vehicle type, Yaw Rate, Position Heading, Acceleration, 50m Collision Warning Vehicle to Vehicle One-way, P2M 10 Hz 100msec Vehicle type, Position, Heading Velocity, Acceleration, Yaw Rate 150m Left Turn Assist 12V and V21 One-way, P2M 10 Hz 100msec Signal Status, Timing, Position, Direction, Road Geom., Vehicle Heading 300m Lane Change Warning Vehicle to Vehicle One-way, P2M 10 Hz 100msec Position, Heading, Velocity, Acceleration, Turn Signal Status 150m Stop Sign Assist 12V and V21 One-way 10 Hz 100msec Position, Velocity, Heading, Warning 300m Table-2.1: Eight high-priority vehicular safety applications as chosen by NHTSA and VSCC. Note that communication freq. ranges from 1-50 Hz and Max. Communication range spam 50-300 meters. P2M represents â€Å"Point-to-Multipoint†, 12V represents â€Å"infrastructure to vehicle† and V21 represents â€Å"Vehicle-to-Infrastructure†. [5] 2.2.9 Comfort related applications Traffic efficiency Better navigation Internet access The whole theme of these applications is improving passengers comfort and traffic efficiency. That includes nearest POI (Points of Interest) localization, current traffic or weather information and interactive communication. All kinds of applications might be applied here. Another application is reception of data from commercial vehicles and roadside infrastructure about their businesses (wireless advertising). Enterprises (shopping malls, fast foods, gas stations, hotels) can set up stationary gateways to transmit marketing data to potential customers passing by. The important feature of comfort/commercial applications is that they should not interfere with safety applications. In this context traffic prioritizing and use of separate physical channels is a viable solution. 2.2.10 Safety related applications Accidence avoiding Danger warnings Intersection coordination Cooperative driving Safety-related applications may be grouped in three main classes: assistance (navigation, cooperative collision avoidance, and lane-changing), information (speed limit or work zone info) and warning (post crash, obstacle or road condition warnings). They usually demand direct communication due to their delay-critical nature. One such application would be emergency notifications, e.g. emergency braking alarms. In case of an accident or sudden hard breaking, a warning is sent to the subsequent cars. That information could also be propagated by cars driving in the opposite direction and, thereby, conveyed to the vehicles that might run into the accident. Another, more advanced example is cooperative driver assistance system, which exploits the exchange of sensor data or other status information among cars. The basic idea is to broaden the range of perception of the driver beyond his field of vision and further on to assist the driver with assistance applications. Transmitting this data to cars following on the same road, drivers get information about hazards, obstacles or traffic flow ahead; hence driving is more efficient and safer. Some applications of this kind are operating only when certain penetration of VANET enabled cars is reached. [6] 2.3 VANETs Characteristics Although VANETs, Wireless Sensor Networks and Wireless Mesh Networks are special cases of the general MANETs, VANETs possess some noticeable characteristics that make its nature a unique one. These properties present considerable challenges and require a set of new especially designed protocols. Due to the high mobility of vehicles, that can be up to one hundred fifty kilometers per hour, the topology of several VANET changes frequently and unexpectedly. Hence, the time that a communication link exists between two vehicles is very short especially when the vehicles are traveling in opposite directions. A one solution to increase the lifetime of links is to increase the transmission power, but increasing a vehicles transmission range will increase the collision probability and mortify the overall throughput of the system. The other solution having a set of new protocols is employing a very low latency. Another effect of these high speed nodes is that the usefulness of the broadcasted messages is very critical to latency. For example, if we assume that a vehicle is unexpectedly stopping or suddenly stops, it should broadcast a message to warn other vehicles of the probable danger. Considering that the driver needs at least 0.70 to 0.75 sec to initiate his response [7], the warning message should be delivered at virtually zero sec latency. In VANETs, location of nodes changes very quickly and unpredictably, so that, building an efficient routing table or a list of neighbor nodes will tire out the wireless channel and reduce the network efficiency. Protocols that rely on prior information about location of nodes are likely to have a poor performance. However, the topologies of a VANET can be a benefit because vehicles are not expected to leave the covered road; therefore, the running direction of vehicles is predictable to some extent. Although, the design challenge of protocols in wireless sensor networks is to minimize the power consumption, this is not a problem in VANETs. Nodes in VANETs depend on a good power supply (e.g. vehicle battery and the dynamo) and the required transmission power is small compared with power consumption of on-board facilities (e.g. air-condition). It is predicted that, as VANET is deployed in the beginning, only a small percentage of vehicles will be outfitted with transceivers. Thus, the benefits of the new technology, especially OBU-to-OBU applications, will not go up until many years. Furthermore, the limited number of vehicles with transceivers will lead to a numerous fragmentation of the network. Even when VANET is fully deployed, fragmentation may still exist in rural areas, thereupon, any VANET protocol should expect a fragmented network. Privacy, safety and security are of fundamental effect on the public receiving of this technology. In VANETs, every node represents a specific person and its location tells about his location. Any requirement of privacy can ease a third party monitoring persons daily activities. However, from the other point of view, higher authorities should gain access to identity information to ensure punishment of illegal actions, where, there is a fear of a possible misuse of this feature. The tampering with messages could increase false alarms and accidents in some situations defeating the whole purpose of this technology. Finally, the key difference between VANET protocols and any other form of Ad-Hoc networks is the design requirement. In VANETs, the key design requirement is to minimize latency with no prior topology information. However, the key design requirement of Wireless Sensor Network is to maintain network connectivity with the minimum power consumption and the key proposed design requirement of Wireless Mesh Network is reliability. WE can summarize the main characteristics of VANETs as follows; High mobility of nodes No prior information about the exact location of neighbor nodes Predictable topology (to some extent) Significant latency requirement especially in cases of safety related applications No problem with power Slow migration rate High possibility to be fragmented Crucial effect of security and privacy 2.4 Research Challenges in VANETs When deploying of a vehicular networking system, a number of issues have to be determined, often from distant fields of expertise, ranging from applications improvement up to efficient issues. VANET could be considered as an instantiation of MANETs (Mobile Ad hoc Networks); however their behavior is fundamentally different. These unique characteristics of these networks are as follows: Rapid topology changes and fragmentation, resulting in small effective network diameter Virtually no power constrains Variable, highly dynamic scale and network density Driver might adjust his behavior reacting to the data received from the network, inflicting a topology change Here we briefly mention some of the core research challenges that need to be discussed. 2.5 Wireless Access technology There are several wireless access standards that could be used as a foundation for VANET technology. In general the major seek is to provide a set of air interface protocols and parameters for high-speed vehicular communication by mean of one or more different media. 2.5.1 Cellular technology (2/2.5/3G) The key role of 2/2.5G i.e. cellular technology are coverage and security, and 3G, slowly but steadily coming over 2/2,5G, provides enhanced and better capacity and bandwidth. Several telematic and fleet management projects already uses cellular technology (e.g. SMS reports), on the other hand it is comparatively more expensive, together with limited bandwidth and latency make it impossible to use as a main communication means. 2.5.2 IEEE 802.11p based technology IEEE is working on a variation of 802.11 standards that would be applied to support communication between vehicles and the roadside, or, alternatively, among vehicles themselves, operating at speeds up to 200 km/h, handling communication ranges as high as 1,000 meters. PHY and MAC layers are based on IEEE 802.11a, shifted to the 5.9 GHz band (5.850-5.925 GHz within US). The technology is promoted by the car industry both in Europe and US. Estimated deployment cost is foreseen to be relatively low due to large production volumes. C. Combined wireless access one of the most significant and important efforts in combining those wireless access technologies is done by ISO TC 204 WG16. It builds on the top of IEEE 802.11p, using additional set of interface protocols. Currently supported standards include: Cellular Systems: GSM/GPRS (2/2.5G) and UMTS (3G), Infrared Communication and wireless systems in 60 GHz band. Using all those interfaces in a single, uniform system would result in incre ased flexibility and redundancy, thus improving applications performance. Apart from interoperability issues, CALM is also engaged in the standardization of the protocols, network layer and the management services. 2.6 WAVE Architecture WAVE system architecture is totally a set of WAVE standards that describes the communication stack of vehicular nodes and the physical air link between them. Any RSU may have two interfaces, one for the WAVE stack or architecture or wireless networks and the other for external interfaces like wired line Ethernet that may be used to get access to internet and for connection to internet it is mainly used. Similarly, each OBU may have two interfaces, one for the wireless WAVE stack and the other for sensor-connections and human interaction. OBU is not full-duplex so, therefore, it cannot transmit messages simultaneously, so DSRC is half-duplex. The RSU and OBU can send messages only when the channel becomes idle and also confirmed that it is idle. If the channel is busy, RSU and OBU need to wait and if the channel is idle then RSU or OBU will send the signal Request to Send (RTS) to control channel. The control channel will allocate the channel on the basis of high priority first followed by low priority. The high priority messages are those messages related to public safety. The WAVE architecture is defined by the IEEE 1609 family of standards and uses the IEEE 802.11p amendment to extend the use of 802.11 to vehicles. The IEEE 1609 family is composed of four standards describing the resource manager, security services, networking services and multi- channel operations. WAVE standard consists of five complementary parts 802.11p â€Å"Wireless Access in Vehicular Environments (WAVE)† [8] which is an amendment to the well known IEEE 802.11 Wireless LAN Standard and covers the physical layer of the system. 1609.1 â€Å"Resource Manager† [8] that covers optional recommendations for the application layer. [13], [14] 1609.2 â€Å"Security Services for Applications and Management Messages† [8] that covers security, secure message formatting, processing and exchange. [13], [14] 1609.3 Networking Services† [8] that covers the WAVE communication stack. [13], [14] 1609.4 â€Å"Multi-Channel Operation† [8] that covers the arrangement of multiple channels and how they should be used. [13], [14] The most evident part is its dual stack. Whereas there is a well-known stack, called TCP/IP stacks and on the other hand there is a stack, called WAVE Short Message stack. The function of the WAVE Short Message stack is to provide a connectionless transport protocol i.e. without checking the connection that whether connection is made or not, similar to UDP but on a single-hop basis. The safety applications are supposed to use this stack only while non-safety applications can use both. It should be noted that the devise or design of this approach is focused on non-safety applications and considers safety as a black box. 2.6.1 IEEE 1609.1 Resource Manager The IEEE 1609.1 standard defines the architecture and data flows of WAVE. It also describes command messages and data formats. [9], [8]. The standard explains how data communication between road side units and vehicle on board units occurs. The discussion of this standards operation will be based on the standard defines applications residing on the on board unit as Resource Command Processors and those residing in road side units or elsewhere as Resource Manager Applications. The Resource Manager is the focus of this standard and is also the application that is responsible for managing communication between multiple Resource Manager Applications and Resource Command Processors. [9], [8] WAVE communication imitates a client-server architecture that is managed by the Resource Manager. For example, in the case where a company wants to provide traffic updates by analyzing vehicle speed statistics in a stretch of highway, the application that analyzes the traffic data (a Resource Manager Application) would reside on the road side unit or a remote server that is connected to a road side unit. When the Resource Manager Application sends a request for the speed of the vehicle the Resource Manager application in the road side unit receives the request then forwards it to the vehicles Resource Command Processor application using WAVE. The vehicle then replies to the Resource Manager which forwards the message to the Resource Manager Application. If another passing vehicle asks for traffic updates by sending a request to the road side unit, the roles of client and server from the previous case are switched. WAVE is designed to provide secure communications and minimize the cost of on board units by minimizing the amount of processing required by them. All only desired information relevant to road safety will be transferred. 2.6.2 IEEE 1609.2 Security Services The IEEE 1609.2 standard defines secure message formats and processing and infers circumstances for using secure message exchange. [13], [8]. It deals with security services for applications and management messages. Security is important in WAVE because vehicles transmit sensitive information that could constitute a violation of privacy if accessed by unauthorized parties. The efficacy and reliability of a system where information is gathered and shared among autonomous entities raises concerns about the authenticity of the received data. For example, a bad actor could misrepresent its observations in order to gain advantage (e.g. a vehicle V falsely reports that its desired road R is stopped with traffic, thereby encouraging others to avoid R and providing a less-congested trip for V on R). More malicious actors could impersonate other vehicles or road-side infrastructure in order to trigger safety hazards. Vehicles could reduce this threat by creating networks of trust, and ignorin g, or at least distrusting, information from un-trusted senders. [13], [8] A trusted communication generally requires two properties are met: The sender is conclusively identified as a trusted source. While in transit, the contents of the senders message are not tampered. WAVE maintains security by ensuring confidentiality and authenticity in message transmissions. The final standard is expected to address privacy issues with the current version. WAVE ensures confidentiality

Adult Civic Education :: Education Adults Essays

Adult Civic Education Since democracy is the context and the condition for everything else that is valued—work, family life, religion, politics, recreation, and leisure—preserving its vitality and integrity must be a central objective of adult education. (Boggs 1991b, p. 54). In a democratic society, adults are frequently confronted with situations and events that require them to make decisions, not only about their own lives as citizens but also about their role as a citizen in a larger community. The answers to dilemmas facing adults in today's world are not clear cut and require the ability to struggle with understanding ideas that are subtle and multifaceted, to engage in serious talk with others, and to take action (Colby et al. 2003; C. Seaquist 2003, p. 11). Since September 11, for example, individuals have had to decide what it means when the "government announces 'specific and credible' clues of a possible terrorist attack" within the United States (L. Seaquist 2003, p. 11). Should they cancel plans for a vacation? Should they stay home and cover their windows with plastic using duct tape? Should they carry on as usual? Furthermore, they also have had to decide if the information itself is credible since being able to interpret intelligence is no w a part of being a citizen (ibid.). How can adult education support adults as they struggle with what it means to be a citizen in an increasingly complex world? This Brief examines the role of adult civic education in contemporary society and provides recommendations for its practice. Adult Civic Education: What Adult civic education, sometimes called adult education for democracy or citizenship education, has a number of purposes and helps individuals carry out both vertical (between the individual and the state) and horizontal (between individuals and groups and communities) aspects of citizenship (Keogh 2003). It involves not only learning about the rights and responsibilities of citizenship (e.g., voting), but also about how one participates in building a society by making informed decisions through dialogue, reflection, and deliberation (Boggs 1991a; Democracy and Peace 1999; Nash 1999). It moves beyond helping learners acquire information and knowledge to fostering the development of action designed to seek solutions to situations (Klaassen 2000). Equipped for the Future, a project of the National Institute for Literacy, for example, organizes content standards for the role of citizen/community member around four broad areas of responsibility as follows: "become and stay informed, form and express opinions and ideas, work together, and take action to strengthen communities" (http://novel.
