Language acquisition Essay

Discuss synchronic and diachronic approaches to language. In opposition to the totally historical view of language of the previous hundred years, Ferdinand de Saussure emphasized the importance of seeing from two distinct and largely exclusive points of view, which he called â€Å"synchronic† and â€Å"diachronic†. The word â€Å"chronic† has been derived from Greek word â€Å"chronos† which means time. Synchronic linguistics sees language as a living whole, existing as a state at a particular point in time (an ital de langue, as Saussure put it, Greek â€Å"syn†-with, chronos – time). Diachronic linguistics concerns language in its historical development (Greek dia through, chronos – time). Thus descriptive linguistics is known as â€Å"synchronic linguistics† and studies a language at one particular period of time. Historical linguistics is known as diachronic or temporal linguistics and deals with the development of language through time. For example, the way in which French or Italian have evolved from Latin, and Hindi from Sanskrit. It also investigates language change. A study of the change from Old to Middle English is a diachronic study. Old English Middle English chint knight  stan ston a o In the same way, the study of a writer’s development from youth to maturity is an example of diachronic study. The way in which Shakespeare’s style changes from youth to maturity is also an instance of diachronic study. Saussure says: â€Å"Synchronic linguistics will concern the logical and psychological relations that bind together co-existing terms and from a system in the collective mind of speakers. Diachronic linguistics, on the contrary, will study relations that bind together successive terms, not perceived by the collective mind but substituted for each other without forming a system. † Thus synchronic linguistics deals with systems whereas diachronic with units. The relationship between the both aspects of language study was diagrammatically represented by Saussure in the following way: C X–X1–X2–X3 B A D Here AB is the synchronic axis of simultaneities, CD is the diachronic axis of succession. AB is a language state at an arbitrarily chosen point in time on the line CD (at X); CD is the historical path the language has traveled, and the root which it is going to continue traveling. The point of intersection X indicates that neither excludes the other completely. If CD represents evolution over a period (say 100 years from 1850 to 1950), X1, X2, X3†¦ represent the successive state of language 1860, 1870, 1880, 1890 and so on. The difference between descriptive or synchronic and historical or diachronic linguistics can be illustrated by the diagram of Saussure itself, who was the first person to point out the necessity of distinguishing between the two approaches. We may think this is fairly obvious distinction if it had not been the case that some quite eminent 19th century scholars had failed to draw it. And it needs to be drawn. Neither excludes the other completely, of course, there must be a point of intersection in terms of the above mentioned diagram. But being aware of, the distinction allows us to focus attention more answeringly on language from a given consistent angle. Moreover, due emphasis on the synchronic (which had been neglected dimension before Saussure) helps to clarify the important point that a diachronic investigation always pre-supposes, to some extent a synchronic study. It is impossible to consider the way a language has changed from one state to another without first knowing something about the two states to be compared. This need not to be a pair of complete synchronic descriptions, of course, to complain that it would be a distortion of what linguists actually do in practice but some nonhistorical analysis is essential as a preliminary. Saussure rounds off his discussion with various analogies, of which his analogy with a game of chess is perhaps the most famous. If we walk into a room while a chess game is being played, it is possible to assess the state of the game by simply studying the position of the pieces on the board (as long as we know the rules): we do not normally need to know the previous moves from the beginning of the game. And likewise the state of board at every move is implicit in any pattern of play we may wish to study. The synchronic/diachronic distinction, Saussure claims, is very much like this. And, without wanting to push the analogy too far, we can agree with him. Throughout the 19th century linguistic research was very strongly historical in character. One of the principal aims of the subject was to group language families on the basis of independent development from a common source, or to study language change. The description of a particular language was made subsidiary to this general aim, and there was little interest in the study of a language of a given community without reference to historical consideration. Saussure’s distinction between diachronic and synchronic investigation of the language is a distinction between two opposing view points. Nevertheless, valid diachronic work has to be based on good synchronic work because no valid statement about linguistic change can be made unless good description of a language does exist. Similarly a synchronic statement may well reflect certain historical developments. For example, two vowels of `reel’ and `real’ are described as being basically different because the historical facts show different sources for the `ee’ and the `ea’. On the other hand, we find statements like `ought’ is the past tense of `owe’ and `dice’ is the plural of `die’. One can point out that these statements are diachronically, but not synchronically, true. A synchronic approach is enough to gain mastery over a contemporary language, but it is necessary to have a diachronic description to understand the evolution of that language.

Emancipation of Women Essay

Women all over the world have become the subject of debate, particularly in the developing countries in Africa, Latin America and some parts of Asia and Middle East. Most women in these parts of the world are victims of male dominance, domestic slavery, sexual oppression and educational deprivation, all of which are generated from religious beliefs or social rigidity against women. Male chauvinists and religious extremists consider women’s enlightenment, emancipation, and urban liberation as culturally wrong, a detachment from family duties such as catering for household chores and raising children. Moralists find the education of women as a western policy of exposing â€Å"the daughters of eve to the naked glue of the naked eyes which will amount to sexual temptations and an invitation to sin with the â€Å"daughters of Jezebel†. Even in the early 19th century, women’s education was seen as a wasteful exercise. Luckily, by the middle of the same century, any negative opinion about women’s education has been decisively opposed. In fact, it was around that time that an old feminist maxim, â€Å"educate a woman, you educate a nation† came to light. Some of the major social problems we have today, such as prostitution and sexually transmitted diseases (STDs), VVF and early marriage, teenage pregnancy can be virtually wiped out by educating women who are directly the victims of these social ills. Otherwise, our national policies or even global agenda aimed at education, social and health development will only be a waste of time without the inclusion of women. In the present century, it is apparent that an educated and happy family is a prerequisite for development. Indeed, it is not an exaggeration to say that a woman is the nucleus of the family, a custodian of the family, and trustee raising the young and future generations. Often, some parents and guardians regard educating a woman as a waste of resources, because according to them, â€Å"they are not full members of the family.† This view is a myopic idea of the African culture, which we must collectively do away with to achieve a balanced development. We should let the primitive way of thinking pave way for sound civilization, if we are to attain sustainable development. Kudos and great bravo to the 1995 International Conference on Women held in Beijing, China, where most of the global problems affecting women were tackled. Some of the issues centred on education and women liberation. Statistics have shown that recent performance of women in various professions such as ICT, arts, politics, academics, research, etc. is a signal to the immeasurable contribution women can give to the world’s development. In conclusion, those who have the view that women’s education is wasteful, have been proven to be living in the past; therefore, they should embrace the global quest for women education for even and sustainable development of the world

History of Brazil Essay

Brazil the only Portuguese speaking country of South America, was founded by Spanish and Portuguese in the same year of 1500, but was handed over to the Portugal in the agreement of Torsdesillas (Bamber Gascoigne,gtu). Since the time of its colonization from 1500 until the late 1930, export of principal products has been subjected. Joao VI the sole sovereign when returned to Portugal, his apparent to the throne was Pedro, who surged a sequence of progressive political differences, which ultimately led to the independence of Brazil by 1822, leading to an era of kingship by Dom Pedro. His son Pedro II continued his legacy and led a more efficient government more than his father till 1889, where he was deposed by military coup. After that there were two more military coups in 1930 and later in 1964, but since 1985, democracy slowly returned to the snagged state. But in the midst of all the political and military drama, somehow the country’s economy was on the move. The history of the country indicates of its troubled pasts, and its love affairs with military coups, but since the last three decades, the country’s political frame has been stable, leading to ample opportunity for company like ours. Brazil Demography and Economy Brazil today has a population of more than 183 million people, with a high literacy rate of more than 86% (BIGS, Brazil today). A very strong positive indication, of a healthy literate population, briefly a very lucrative consumer mass for our product. Brazil comes in one of the front leaders of a leading economy in the world. It is an elite member of trillion dollar GDP group of the world. It is one of the fastest growing economies of the world, and slowly but surely, this country has become members of varied monetary unions, like Mercosur, and G-20. Brazil’s GDP has grown at an alarming 5. 1 % in the financial year of 2007, and with a very strong GDP per capita income of $8800 and also the Brazilian currency BRL$ is very strong, as 1 USD is near about less than BRL$ 2. This 8th largest economy of the world would prove to provide substantial buyers of our product in due course of time. Brazil’s Lifestyle Brazilian culture is a very open culture, with very less of taboos, and from the early times has been into music, and dance. Being a highly diversified culture with a huge mix of ethnic groups, Brazil has a very rich heritage. Music is one of the lifelines of Brazilians, and it can be stated form the fact that, way before their independence, Brazil had its own set of music schools, set up in different part of the country . This 5th largest population of the world is very inclined to towards singing and dancing customs, and being a prosperous nation 98% of the large population has access to television, where their local movie industry which also being the 10th largest in the world is highly well-liked and watched. Brazil’s inclination towards sports is not hidden from the world, and especially their superior liking for football. The population in general is known to be very hard working, but very apposite to recreation in sports and music. Status of demands of subwoofer in cars Brazil has a very large automobile industry, and in the year 2005, Brazil manufactured more than 1.65 million cars only for its domestic market (Elisangela Cordeiro), also according to the Euro monitor consumer electronics reporting Brazil, the in-car electronics such as woofers and media players along with other electronics in the market are available at cheap installment schemes, which are luring the common man into packing his car with accessories, like car speakers and woofers. Brazil has got a very huge young population, which would be our main targets for our products, as woofers are a very mandatory thing for the young generation of Brazilians. Recommendation Our first strategy to enter Brazilian woofer market is to tie up with the local car manufacturers, and to fit in our woofers in the local brands at reasonable prices. Since Brazil has a huge automobile market, we can tap into its boom and accessories the cars with our woofers. Secondly, the basic nature of a Brazilian is very open, and everyone has very strong interest in the different genres of music, we can capitalize on this nature of theirs and we can have ads on the lines of their open nature along with, their music, being played by our subwoofer. The only competition from a brand as repute as ours is from the company â€Å"BOSE†, but it only has its sales distributors, retail and commercial in Sao Paulo, if we can pull up our regional centre in Sao Paulo as well as the capital Brasilia , then we would be miles ahead of BOSE in the Brazilian sphere, as we would be able to reach a lot of people with our products, also these two cities are the main hotspot places for tourists, mainly coming from other regions of Latin America, and we would start catering to the domestic as well as the other Latin American mass would enhance the company’s reputation in nationally as well as in other neighboring countries. We can have our shops in malls and in different youth oriented streets and places, apart from having our outlets at car showrooms. Another thing that is strongly recommended is to tap into local manufacturing structure as Brazil has a very high amount of labor population who work at remunerations which are much aff ordable to us than the labor unit in the US, also the transportation costs would exceed cost price of our product. It is more suitable to link up with government in Brazil for facilitating us with the required formalities, and also the required waivers being handed out to us, in return for the unit which would commence in Brazil, in turn handing out jobs to the local population. Once we establish our market in the region, we can market our product more to the masses by making changes in its core design and, we can create an innovative JBL series subwoofer, which can be in a shape of a football (sphere), which would woo youngsters and football lovers. Further details regarding this matter will be mailed to you from the Research& Development wing. Conclusion Brazil has a very booming economy, and it is being rated with countries like India and China who are, the fastest growing economies of the world. This country has a very reasonable labor population which would cut down our costs by a huge margin, when we start manufacturing here. The regional centers which I have recommended would enhance our market in the country, and we if we can tap into the free nature and love of music of the Brazilians , then we would have not only a huge market in this country but also other Latin American countries who would follow Brazil’s in pursuit. Apart from Brazil’s distressed past of military coups, there is nothing else that negates Brazil as one of the prime future market for our company Work Cited Bamber Gascoigne, â€Å"History of Brazil†, Jan 14th 2008 http://www. historyworld. net/wrldhis/PlainTextHistories. asp? historyid=aa88

Poetry Explication Essay Example | Topics and Well Written Essays - 750 words

Poetry Explication - Essay Example This means that the other half was inside the water. In the human world, the fish is an alien organism, while in the water, the fish is at home. To the fisherwoman, the fish is unpleasant organism, and it is weak (Bishop, 1983). It is therefore a victim of humanity, and it is vulnerable to the whims of the mankind. This paper analyzes the use of symbolism in the poem. This is because the entire poem is full of symbolism, which is used to explain the relationship that exists between man and the aquatic world. The poem by Elizabeth Bishop is not organized into stanza, but it is written in a prose form. It is kind of a narration that a fisherwoman gives on her experiences when she was out fishing. This poem is not rhythmic in nature, and the words used are easy to understand. This is even though there is a lot of symbolism and stylistic devices in it (Bishop, 1983). Furthermore, the poem is very descriptive in nature. The narrator of the poem manages to describe how the fish looked like, and the emotions that she felt towards the fish. She felt pity, and this is because the â€Å"Fish† was weak and vulnerable to human activities. There are numerous stylistic devices used in this poetry, and an important one is symbolism. The description that the speaker describes the â€Å"Fish† resembles as if it is dead, rather than alive (Bishop, 1983). Furthermore, the fact that the aquatic animal is caught means that death is imminent. For instance, the narrator denotes that the stripes of the Fish brown skin looked like an ancient wall paper, and the patterns of these wall papers were lost through the ages (Bishop, 1983). Furthermore, the narrator denotes that the Fish is bespeckled, and it is covered with white sea lice. This is a symbol of death. In symbolizing death, the narrator further denotes that the Fish is covered in rags of green weed. The narrator was

Foreign Direct Investment - Essay Example Foreign Direct Investment refers to the investments that a multinational firm makes when it is initially located in one country but decides to locate to or acquire substantial production facilities in another country. FDI is a significant factor in operation of MNCs. As Bernard, Jensen and Schott [2] point out, its importance to the U.S. economy is demonstrated by the fact that about 90% of all exports from and imports into the U.S. flow through a U.S. MNC while roughly 50% of the trade flows in fact occur between subsidiaries or affiliates of the same MNCs.[2]. Foreign Direct Investment in another country could take place through the financing of new investments within the target country or even through mergers and acquisitions of local firms and production facilities, etc by a multinational entity, with the value of mergers increasing from 52% of the FDI in 1987 to 83% in 1999, as per UNCTAD [13].1.2:  Ã‚  Ã‚   Benefits of Foreign Direct Investment:  Foreign Direct Investment c an be beneficial to a multinational firm in several ways and Isobe et al [8] have examined the multinational firm in the context of technology transfer. They have examined the impact of early movers in technology within emerging economic regions as far as performance is concerned by studying 220 Japanese multinational companies that have set up their business in China. The findings in this study suggested that a multinational firm gains from technology transfer especially when the degree of commitment of the firm is high.

Critical Response 2 - Research Paper Example The suspension of Frederick is nullified as it did not cross the ethical and moral boundaries. What it did was to inculcate among others Frederick’s own sentiments which were flawed in their own right. He did not know what he was inculcating, and hence is not charged for the same. Had he known he was doing something irresponsible, and still committed to the act, he would have been charged in a manner which was seemingly fit. Therefore I acquit Frederick of any charges against him which are a result of the hate that exists in line with drugs and their usage. I give him the margin as he can spend his life with a sense of understanding and people shall empathize with him in the coming times. In all fairness and going by the rule of law, Frederick stands not guilty and is therefore free from all charges and banishments against him. References Burns, S. L. & Peyrot, M., 2010.

Quasi Zenith and Beidou2 Satellite systems Essay

Quasi Zenith and Beidou2 Satellite systems - Essay Example The GPS or Global Positioning System, which first became popular as a means of car navigation have become widespread with their integration in mobile phones. A navigation signal can point to an exact location with the help of at least four satellites but in areas whose geographical terrains are populated with mountains, the satellites signals can be hampered by their presence and the same is true in urban areas where skyscrapers abound. Mountains, skyscrapers and other tall structures, manmade or otherwise, can cause signal errors. The QZSS and the BeiDou-2 Satellite Systems were launched to remedy such situations. In 2003, Japan launched the Quasi-Zenith Satellite System that will provide a regional satellite positioning service in addition to communication and broadcasting services. This is the first satellite positioning of Japan and it is a joint effort of government and private sectors. The Advanced Satellite Business Corporation or ASBC is a private company that is tasked with the development and operation of the communications and broadcasting functions of the satellite system. Four ministries of the Government, on the other hand, are tasked with the development of the satellite positioning system.

Research Paper for Organizational Change Essay Example | Topics and Well Written Essays - 1750 words

Research Paper for Organizational Change - Essay Example In addition, there is high degree of favoritism in the company. In order to implement successful change, it is necessary to identify the problems and their underlying reasons. It is identified that the company runs 365 days a year, seven days a week, and 24 hours a day. In addition it is pointed out that there is a general lack of safety at the workplace. Moreover, nepotism and lack of supervision are clearly visible to all. It is very evident that there is the need for a total change in the organization’s culture if these problems are to be addressed. However, simple discussions of change will not help solve the problem as the old culture will reemerge in a short while. On the other hand, as Hebert (2009) points out, in order to successfully implement a plan for organizational cultural change, the human resources department of the company should secure leadership and ensure employee participation in the change process. Evidently, leadership buy-in and employee participation a re two sides of the same coin. Once the human resources department manages to get total control, it should ensure that all the affected parties are a part of the changing process and are committed to it. Participation in the change process ensures that employees understand their stake in a successful outcome. However, even though there is active employee participation, there is very high possibility of cognitive discord. So, it is for the human resource department to identify this element of disagreement throughout the change and provide guidance. The issues It is recognizable from the description that there is low morale among the employees from top to bottom. The first thing that is found lacking here is motivation. As is evident from studies (Clegg, Kornberger & Pitsis, 2005, p. 253), all people are motivated intrinsically and extrinsically. However, most people show preference of one form of motivation to another. In the case of this company, it is highly necessary to avoid the authoritarian management practices and the evident nepotism. So, it becomes highly necessary for the human resource management department to make its managers and supervisors aware about the need to ensure intrinsic and extrinsic motivation. In fact, studies have proved that more than two-thirds of employees want to get appreciated in their jobs. In addition, it is proved that when verbal praise and recognition are given both publicly and privately, they produce great efforts. Some other forms of intrinsic motivation are challenging work assignments and schedule flexibility. It is evident that when used appropriately, intrinsic and extrinsic motivation help improve employee morale. Another point of consideration is operational issue. To ensure product quality, the key is monitoring and measuring processes and making any necessary adjustments. Here, the concept of Panopticon as proposed by Bentham seems useful. According to him (as cited in Clegg, Kornberger, & Pitsis, 2008, p. 18), it is effective to ensure performance quality if there is a belief among the employees that they are being observed, but by an unseen being. In other words, if the principle of inspection and surveillance is properly instilled, it can ensure that the employees will feel responsible for what they do and say. The benefits of Panopticon are enormous. It can act as a system of records and rules, making each of the staff feel responsible

Qualifications & Selection Process for Judges in Illinois & Florida Essay

Qualifications & Selection Process for Judges in Illinois & Florida - Essay Example The candidate should also have a record of good behavior and integrity as well as capable of communicating both in spoken and written English. On condition that an individual does not meet the above named qualifications then it means that he or she is not eligible to vie for any judiciary position in the state of Illinois (Sara, 2005). The judiciary of Illinois consists of the supreme, appellate, and circuit courts. The judges are first elected through partisan elections where they are capable of serving ten year terms but on condition that there exist a vacancy on the court; then a supreme court appointment is necessary. The other serving justices have the role of electing the chief justice of the court where he serves for three years only. As for the appellate courts in Illinois, the conditions are similar in exception of the condition that the chief justice is only supposed to serve for one year term. The chief justice in circuit courts serves an indefinite term but the judges can serve a six year term (Charles & Maule, 2003). Judges in Illinois can be dismissed from work through an inquiry from the judicial board after complains are launched by the commission of the court. After a hearing, the commission has the authority to suspend or completely dismiss a judge from tenure if he or she is found to have acted in a substandard manner. Alternatively, judges can also be dismissed from work through a majority vote from the House of Representatives as well as a majority of two thirds of the senate vote (Sara, 2005). In Florida, the judicial system consists of four levels and in our case study we are going to limit our research on the first level; the level of a County Court Judge. To qualify for the position of a County Court Judge in Florida, an individual must have been a member of the Florida Bar for a period of not less than five years in addition to the fact that he or she must be a member of the county he or she is vying for to serve even

Introduction The question as to which language should be used as a medium of instruction in country like India is a debatable subject. The question is often posed in binary terms: Should the medium of instruction be a regional language or English? Language is a vehicle for learning as well as expression of ideas. An advanced language (English) helps in mentally provide people to  communicate each other across the world. On the other hand, an underdeveloped language has its limitations. It keeps people underdeveloped, more so those in deprived sections.

Historical View of the Language Policy in Indian Education The historical view of the evolution of the language policy in India let know us how the importance of English and its role in Indian Education. India is multilingual country. It has been reflecting in the formulation of the language policy. The Indian constitution has provided that the primary education must be taught through the mother tongue or regional language. However, a status survey of language instruction in the country exposed that of the 1652 mother tongues listed by the 1961  Census, there are 51 languages which are spoken by more than The present paper can be divided into four parts. The first part 100,000 people each. Of these 51 languages, 16 have no script of will highlight the language policy after Indian Independence. their own, and only the remaining 35 languages are accepted as The second part discusses the concept of mother tongue and its media of instruction at the school level1. English is a common importance in the contextualizing of educational discourse in  language and it is an obligatory language in the higher education The National Council of Educational Documented the demand and importance of English language in  the position paper in connection with the National Curriculum The Indian  government has been following three-language Framework (2005) as they stated: â€Å"English in India today is a formula in Education as the National Commission on Education symbol of people’s aspirations for quality in education and fuller 1964-1966 recommended.

Finally they came up with conclusion that three-language formula must be included There is an astonishing faith among all sections of the society in in the context of  multilingual Indian educational system. I argue both rural and urban areas that English has the transformative that once upon a time the English language was important part of power language. English is seen not just as a skill language, but a mechanism of exclusion language due to upper caste as a means of a better life, a pathway out of exclusion and nationalists’ creation as they differentiated native language and suppression from the unequal society. The English language has alien language but now it can be seen as a tool of inclusion. In emerged as a powerful agent for social change in India. the post modern India the English language is important factor to include all the sections of Indian society. The main reason is an Mother Tongue as the Medium of Instruction increasing demand for the language which is an important tool There is a popular perspective that advocates the use of mother for the progress and development of the country. Encourage linguistic diversity in schools. This perspective argue that mother tongues are not merely speech varieties but are  languages that provide social and emotional identity to  individuals, express the essence of their cultures, and give them a sense of rootedness. Schooling in the language of the child reflects respect for her and an appreciation of her culture. The exclusion of the mother tongues from school hence is seen as ‘harmful to the child’s self esteem’. According to Pattanaik5 children are thereby â€Å"reduced to  minorities in their own homes†. Extending the realm of  pedagogy, the argument links the acknowledgement and  acceptance by the school of the language and culture of the child to a positive identity of self and thereby to effective educational achievement. As Edward says, â€Å"the rejection of a child’s language is unlikely to enhance feelings of self worth which are important for educational success†6. Further, this perspective argues that â€Å"the right to education in a language that the child understands is a basic human right and an essential ingredient of equality in education†. Pattanaik forcefully observes that to â€Å"control and dictate the language of access† to knowledge is a â€Å"positive suppression of human talent. It deprives individual and society of free choices, curbs creativity and innovativeness and restricts participation or potential participation in mul tiple spheres of human interaction, thus imposing limits on freedom†. Current Debate on Medium of Instruction Current language politics in India is an exemplary case of the issues and controversies surrounding linguistic globalization. A primary characteristic of linguistic globalization is the increasing spread and domination of the English language, which we can  capture by the term ‘global English’8. As a post-colonial democracy, India provides a context for examining linguistic globalization that is generalizable to other cases. Furthermore, in juxtaposition to the homogenizing tendency of global English, India embraces multilingualism; its federal system is based on its linguistic diversity. India’s first Prime Minister, Jawaharlal Nehru, a modern  socialist at heart and one of the premier leaders at the 1955 Bandung conference, was utterly convinced of this linkage  between the English language and technology and modernity9.  Yet he also â€Å"discovered India† through its rich and enduring diversity.

Most Beautiful And Interesting Buildings In History Construction Essay

Most Beautiful And Interesting Buildings In History Construction Essay During modern era nowadays, exciting new innovations in the world of building construction has brought soaring skyscrapers and fresh new approaches to building design. Actually since many years ago building construction was a significant part of our industrial field. If somebody asks what is the most significant, most beautiful and most interesting of the past 1000 years, there will be no single correct answer for this question. Some will choose the Taj Mahal or Eiffel Tower while others might choose the soaring skyscrapers as the most significant building. Perhaps the most innovative building is not fixed for the grand monument only but sometimes obscure home and temples also. These are some of overlooked treasure that still exists till now. The first one is Forbidden City in Beijing,China or some people called it as Purple Forbidden City or Gugong Museum in Chinese. It is one of the largest and best-preserved palace complexes in the world. In Gugong Museum there are over a million rare and valuable objects. It is built between 1406 and 1420 during the Ming Dynasty by a rectangular area of more than 720000 square meters. The Forbidden City was the imperial home for 24 emperors of the Ming ( 1368-1644) and Qing (1644-1911) dynasties. http://s1141.photobucket.com/albums/n589/nadiahasbullah/?action=viewHYPERLINK http://s1141.photobucket.com/albums/n589/nadiahasbullah/?action=viewcurrent=pic1.jpgHYPERLINK http://s1141.photobucket.com/albums/n589/nadiahasbullah/?action=viewcurrent=pic1.jpgcurrent=pic1.jpg Next is Basilica Palladiana building. The architect who was Andrea Palladio gave the Basilica in Vicenza, Italy two styles of classical columns which are doric on the lower portion and ionic on the upper portion. Originally, the Basilica was a 15th century Gothic building that serve as the town hall for Vicenza and also contained shop. When the old building collapsed, Andrea Palladio won the commission to design a reconstruction of this building. He grabbed this opportunity and created a great stunning transformation covering the old gothic facade with marble columns and porticos modelled after the classical architecture of ancient Rome. http://s1141.photobucket.com/albums/n589/nadiahasbullah/?action=viewHYPERLINK http://s1141.photobucket.com/albums/n589/nadiahasbullah/?action=viewcurrent=pic2.jpgHYPERLINK http://s1141.photobucket.com/albums/n589/nadiahasbullah/?action=viewcurrent=pic2.jpgcurrent=pic2.jpg Eiffel Tower in Paris is also one of past greatest building construction. Eiffel Tower was built on 1889 and pioneered new uses for metal construction. Perhaps it was the most famous example of this new use for metal. With 324 feet, Eiffel Tower was measured as the tallest building structure in the world for 40 years. The metal lattice-work formed with very pure structural iron make the tower both extremely light and able to withstand tremendous wind force. During the construction, the Eiffel was considered as an eyesore for the French but the criticism died down once the construction was completed. http://s1141.photobucket.com/albums/n589/nadiahasbullah/?action=viewHYPERLINK http://s1141.photobucket.com/albums/n589/nadiahasbullah/?action=viewcurrent=pic3.jpgHYPERLINK http://s1141.photobucket.com/albums/n589/nadiahasbullah/?action=viewcurrent=pic3.jpgcurrent=pic3.jpg The Fuller Building in New York is one of the worldà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s earliest skyscrapers and has been designed by Daniel Burnham architect. It was built on 1902 with a height of 285 feet. The wedge shaped like a clothing iron of this building make it became known as Flatiron Building. This unusual shape of building is because to maximize the use of the triangular lot. A sturdy steel skeleton that has been used during the construction of this building allowed it to achieve record-breaking height without the need for wide supporting walls at the foundation. http://s1141.photobucket.com/albums/n589/nadiahasbullah/?action=viewHYPERLINK http://s1141.photobucket.com/albums/n589/nadiahasbullah/?action=viewcurrent=pic4.jpgHYPERLINK http://s1141.photobucket.com/albums/n589/nadiahasbullah/?action=viewcurrent=pic4.jpgcurrent=pic4.jpg Nowadays, there is many and more big challenge facing us. The technology shifts had made the construction technology today more advanced and the world is getting smarter. The construction methods, structure or sustainable building, design and the construction system are rarely important not only at national level but also globally. The example of advance construction building in the world now are the CCTV headquarter in China, Bird Nest Olympic Stadium, Khalifa Building at Dubai and some of other buildings. One of the form that being used today is insulated concrete from construction technology. Insulated concrete form are lightweight, highly durable foam blocks or forms composed of an expanded or extruded polystyrene and recycled materials. These are the formwork that stay a permanent building insulation fore cast in place, reinforced concrete walls, floor and roofs. The forms are consisted of interlocking modular units that are dry stacked and concrete filled. The forms just like LEGO bricks that create form for structural walls or roofs. The concrete is pumped into cavity and stacked in shape. The reinforcing steel bar is placed inside to give flexural strength. The forms are left permanently for the reason of thermal and acoustic insulation and the space to run electrical conduit and plumbing. The advantage of insulated concrete form is that it reduces the consumption of energy, the concrete will absorb solar heat and release it slowly so that heat is distributed throughout the home. Besides it create lower noise from outside world as it high in sound absorption and the system contribute to more peaceful and healthy environment. Over the past 30 years, construction practices had not really changed much because many people thought that there are no problems using the traditional practices. However, for current situation the old practices might be not practical anymore due issues that involved limited area and construction costs that continue to rise in the country and also around the world. Therefore, by using the effective method of construction, we actually can overcome these problems. After several researches that consider all of the elements, there are some methods that believe can practices in the future such as modular construction and sustainable construction (green construction). By using these methods to construct a building, a lot of benefits we could gain in terms of time consuming, capital cost, labour cost and so on. In Malaysia, modular coordination or construction in building had been practiced such a long time ago. It is well documented in Malaysian Standard MS 10064: Part1-10 2001. This practices can provides dimensional basis for the coordination of the dimensions and of those buildings incorporating them, however it also acts to rationalization and industrialization of the building industry. In addition, modular construction can be applied by adding or reducing the size or removing certain components. For developing country likes Malaysia, this method will help the contractor to face the project that running in busy area or high capacity area because it is speed construction and faster returned in investment. In common method of construction, once projects might need to be done in 12 months but by practicing modular construction the work can be done in 90 à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬ 120 days only. This is because, the buildings are sectional prefabricated buildings that consist of multiple modules or sections which are manufactured in a remote facility and then delivered to the site. Modular construction allows the building and the site works to be done simultaneously and this will reduce the time until 50%. Furthermore, the quality of modular buildings is made to match and adhere to all the same building codes as standard construction. Thus, when the building is rebuild the structure become high in quality compared with the previous structure. Moreover, by using this method, all problems involve weather delays, logistical problems and legal hassles increase in turn can be solved because the structure is not build in the site. A lot of advantages we can gain based on modular construction and it is not hard to imagine if the future commercial developments are completed by using this method. http://s1141.photobucket.com/albums/n589/nadiahasbullah/?action=viewHYPERLINK http://s1141.photobucket.com/albums/n589/nadiahasbullah/?action=viewcurrent=pic5.jpgHYPERLINK http://s1141.photobucket.com/albums/n589/nadiahasbullah/?action=viewcurrent=pic5.jpgcurrent=pic5.jpg Modular house by Broadway Malyan for Sime Darby Property as a first carbon zero house in Southern East Asia. http://s1141.photobucket.com/albums/n589/nadiahasbullah/?action=viewHYPERLINK http://s1141.photobucket.com/albums/n589/nadiahasbullah/?action=viewcurrent=pic6.jpgHYPERLINK http://s1141.photobucket.com/albums/n589/nadiahasbullah/?action=viewcurrent=pic6.jpgcurrent=pic6.jpg The house not only pushed costs expand but also speed up the construction process On the other hand, sustainable construction is one of the practices that might be used widely in future. It involves a greater emphasis on the environmental implication of policy and business decisions in addition to the traditional focus on economic and social objectives. Sustainable building can include measures to reduce energy consumption and associated emissions of carbon dioxide, minimize the use of resources such as water, construction material, etc., reduce the release of pollutants, maximize the use of sustainably sources and recycled materials likes timber, promote sustainable travel choices through public transport and cycling provision, save and enhance biodiversity. Example of sustainable building is building that use sunlight through passive solar, active solar and photovoltaic techniques and using plants and trees through green roofs, rain garden and for reduction of rainwater run-off. Besides that, by using packed gravel or permeable concrete instead of conventional c oncrete or asphalt to enhance addition ground water, are used as well. Nevertheless, based on the study done by some researchers, the department usually failed to achieve target ratings and environmental assessment by the government. 80% of the projects are not attained the required standards. Various factors lead to these problems are lack of coherent monitoring on the progress of the projects by the government bodies, lack of sufficient knowledge and expertise in sustainable procurement among those department staff responsible for them, negative perception about the conflict between sustainability and value for money and so on. However, this barriers can be solved by establish a clear information to the division of policy that responsible on sustainable construction to the public sector so that the public will acknowledge clearly about the policy of sustainable construction. Then the responsible division can also establish a source of expertise that available to all departments to provide advice on sustainable construction for smaller construction and refurbishment projects. http://s1141.photobucket.com/albums/n589/nadiahasbullah/?action=viewHYPERLINK http://s1141.photobucket.com/albums/n589/nadiahasbullah/?action=viewcurrent=pic7.jpgHYPERLINK http://s1141.photobucket.com/albums/n589/nadiahasbullah/?action=viewcurrent=pic7.jpgcurrent=pic7.jpg Bird Island is currently developed in Kuala Lumpur. Designed by Grafts Lab Architect for YTL Green Home Competition. In a nutshell, for future building construction, all elements of environmental friendly must be considered in order to construct a building or structure. This is because as we know, we need to save our Earth by reducing energy costs such as electrics, reduce air quality and construction materials and many more. Therefore, by applying modular construction and green construction will lead us to help our nature.

Reality of Unification Theory

Reality of Unification Theory Introduction Unification means: finding the similarities, finding the limiting physical constants, finding the key numbers, coupling the key physical constants, coupling the key physical concepts, coupling the key physical properties, minimizing the number of dimensions, minimizing the number of inputs. This is a very lengthy process. In all these cases observations, interpretations, experiments and imagination play a key role. The main difficulty is with interpretations and observations. At fundamental level understanding the observed new coincidences and confirming the observed coincidences seem to be a very tough job. Constructing semi empirical relations among the physical constants of various interdisciplinary branches of physics with all possible interpretations may help in resolving the issues. Which way/method is the best will be decided by future experiments, observations and interpretations. As it is interconnected with all branches of physics, ‘semi empirical approach’ se ems be the easiest and shortcut way. It sharpens and guides human thinking ability in understanding the reality of unification. For any theoretical concept or mathematical model or semi empirical relation, ‘workability’ is more important than its inner beauty and ‘workability’ is the base of any semi empirical approach. In this paper by introducing the unified mass unit the authors made an attempt to fit and understand the origin of the nuclear charge radius, the Planck’s constant and the strong coupling constant in a unified approach that connects gravity and strong interaction via the electromagnetic and gravitational force ratio of proton and electron. Finally by considering the proton rest energy and the nuclear charge radius the authors made an attempt to fit the semi empirical mass formula energy coefficients in a very simple way. To fit the nuclear charge radius, the Planck’s constant and the strong coupling constant It is well known that e, c and G play a vital role in fundamental physics. With these 3 constants space-time curvature concepts at a charged particle surface can be studied. Similar to the Planck mass an interesting unified mass unit can be constructed in the following way. (1) Note that plays a crucial role in microscopic physics as well cosmology. It is having a long history. It was first introduced by the physicist George Johnstone Stoney [1]. He is most famous for introducing the term ‘electron’as the ‘fundamental unit quantity of electricity’. With this mass unit in unification program with a suitable proportionality it may be possible to represent the characteristic mass of any elementary charge. It can be considered as the seed of galactic matter or galactic central black hole. It can also be considered as the seed of any cosmic structure. If 2 such oppositely charged particles annihilates, a large amount of energy can be released. It is well assumed that free space is a reservoir for pair particles creation. If so under certain extreme conditions at the vicinity of massive stars or black holes, a very high energy radiation can be seen to be emitted by the virtue of pair annihilation of . Note that the basic concept of uni fication is to understand the origin of ‘mass’ of any particle. Mass is the basic property in ‘gravitation’ and charge is the basic property in ‘atomicity’. So far no model established a cohesive relation in between ‘electric charge’ and ‘mass’ of any ‘elementary particle’. From astrophysics point of view the fundamental questions to be answered are: 1) Without charge, is there any independent existence to ‘mass’ of any star? 2) Is black hole – a neutral body or electrically a neutralized body? To understand these questions the authors made an attempt to construct the above unified mass unit. The subject of final unification is having a long history. After the nucleus was discovered in 1908, it was clear that a new force was needed to overcome the electrostatic  repulsion of the positively charged  protons. Otherwise the nucleus could not exist. Moreover, the force had to be strong enough to squeeze the protons into a volume of size 10−15 meter. In general the word‘strong’is used since the strong interaction is the â€Å"strongest† of the four fundamental forces. Its observed strength is around 102 times that of the  electromagnetic force, some 105times as great as that of the  weak force, and about 10 39 times that of  gravitation. The aim of unification is to understand the relation that connects ‘gravity’, ‘mass’, ‘charge’ and the ‘microscopic space-time curvature’. Many scientists addressed this problem in different ways [2-4]. The authors also made many attempts in their previousl y published papers [5-11]. Experimentally observed nuclear charge radius [12-15] can be fitted with the following strange and simple unified relation. (2) Here can be considered as the Schwarzschild radius [16,17] of the proposed new mass unit . (3) Whether the expression playing a ‘key unified role’ or ‘only a fitting role’ to be confirmed. With a great accuracy the famous Planck’s constant can be fitted with the following relation. (4) Recommended value of and the error is 0.189%. From relations (1) and (2) above relation can be simplified into the following simple form. (5) Comparing this with the standard definition, (6) where is the fine structure ratio. Let (7) Proceeding further qualitatively and quantitatively currently believed strong coupling constant [18] can be fitted with the following relation. (8) Its recommended value is 0.11847 and uncertainty is ppb. Now the characteristic nuclear force can be expressed as follows. (9) Note that can be considered as the limiting magnitude of any kind of force. Similarly can be considered as the limiting magnitude of any kind of power [1,20,21]. To fit and co-relate the semi empirical mass formula energy coefficients In nuclear physics, the semi-empirical mass formula is used to approximate the mass and various other properties of an atomic nucleus. As the name suggests, it is based partly on theory and partly on empirical measurements [23-24]. The theory is based on the liquid drop model proposed by George Gamow, which can account for most of the terms in the formula and gives rough estimates for the values of the coefficients. It was first formulated in 1935 by German physicist Carl Friedrich von Weizsacker, and although refinements have been made to the coefficients over the years, the structure of the formula remains the same today. In the following formulae, let be the total number of nucleons, Z the number of protons, and the number of neutrons. The mass of an atomic nucleus is given by (10) where and are the rest mass of a proton and a neutron, respectively, and is the binding energy of the nucleus. The semi-empirical mass formula states that the binding energy will take the following form. (11) Its modern representation is (12) Here = volume energy coefficient, is the surface energy coefficient, is the coulomb energy coefficient, is the asymmetry energy coefficient and is the pairing energy coefficient. By maximizing with respect to , one can find the number of protons of the stable nucleus of atomic weight as, (13) This is roughly for light nuclei, but for heavy nuclei there is an even better agreement with nature. Now with the following two energy units semi empirical mass formula energy coefficients can be fitted in the following way. Let (14) where, (15) The coulombic energy coefficient can be expressed as (16) The asymmetry energy coefficient can be expressed as (17) The pairing energy coefficient can be expressed as (18) The surface energy coefficient can be expressed as (19) The volume energy coefficient can be expressed as (20) Thus (21) For light and heavy atoms (including super heavy stable isotopes), proton-nucleon stability relation can be expressed with the following semi empirical relation. Clearly speaking by considering its corresponding stable mass number can be estimated directly. (22) where can be considered as the stable mass number of (23) Please see table-1 for fitting the proton number and its corresponding stable mass number.

Right now and till today ‘string theory’ with 4 + 6 extra dimensions not in a position to explain the unification of gravitational and non-gravitational forces. More clearly speaking it is not in a position to bring down the Planck scale to the nuclear size. Note that  general relativity  does not throw any light on the ‘mass generation’ of charged particles. It only suggests that space-time is curved near the massive celestial objects. More over it couples the cosmic (dust) matter with geometry. But how matter/dust is created? Why and how elementary particle possesses both charge and mass? Such types of questions are not being discussed in the frame work of general relativity. The first step in unification is to understand the origin of the  rest mass  of a charged elementary particle. Second step is to understand the combined effects of its electromagnetic (or charged) and gravitational interactions. Third step is to understand its behavior with surroundings when it is created. Fourth step is to understand its behavior with cosmic space-time or other particles. Right from its birth to death, in all these steps the underlying fact is that whether it is a strongly interacting particle or weakly interacting particle, it is having some rest mass. To understand the first two steps somehow one can implement the gravitational constant in sub atomic physics. In this regard can be considered as the nature’s given unified mass unit. To bring down the  Planck mass  scale to the observed elementary particles mass scale certainly a large scale factor is required. In this regard, the electromagnetic and gravitational force ratio of proton and electron can be considered as the nature’s given universal scale factor. Thinking positively the proposed relations for fitting the nuclear charge radius, the Planck’s constant and strong the coupling constant can be considered for further analysis positively.

The Healing Process Essay -- essays research papers fc

The Healing Process This is a brief psychological overview of the healing process. The image of healing is best described by Gloria Vanderbilt in "A Mother's Story" when she talks of breaking the invisible unbreakable glass bubble which enclosed her that kept her always anticipating loss with echoes of all past losses. She wrote, for example (Page 3),"Some of us are born with a sense of loss there from the beginning, and it pervades us throughout our lives. Loss, as defined, as deprivation, can be interpreted as being born into a world that does not include a nurturing mother and father. We are captured in an unbreakable glass bubble, undetected by others, and are forever seeking ways to break out, for if we can, surely we will find and touch that which we are missing". This concept of healing was also described by Philip Berman in "If It Is Not Good Make It So" as changing positively from the unhappy attitude of(Page 48) "we never got the habit of happiness as others know it. It was always as if we were waiting for something better or worse to happen". Psychological theory of change suggest it is possible to heal, to break out of the glass bubble, to develop the attitude of happiness. For example, in "The Process of Change: Variations on a Theme by Virginia Satir says on Page 89 that "successful change-making turns out to involve struggle, necessitating skill, tenacity and perspective". The struggle occurs when a foreign element produces chaos until a new integration occurs which results in a new status quo. Kurt Lewin echoed this view in saying that an old attitude has to unfreeze, the person experiments, a new attitude develops and a refreezing occurs. Janis and Prochasky suggest a person starts in relative complacency, is presented with challenging information, the person evaluates the new challenge to habit or policy and reviews alternate policies to create a new policy or return to the original one, The psychological theories focus on perspective and rational thought. The significance of the therapist is in giving a new perspective and in aiding self-esteem in order to break down resistance to change.

Immaturity of Holden in J.D. Salinger’s The Catcher in the Rye Essay

Immaturity of Holden in J.D. Salinger’s The Catcher in the Rye In J.D. Salinger’s The Catcher in the Rye, the main character, Holden, cannot accept that he must move out of childhood and into adulthood. One of Holden’s most important major problems is his lack of maturity. Holden also has a negative perspective of life that makes things seem worse than they really are. In addition to Holden’s problems he is unable to accept the death of his brother at a young age. Holden’s immaturity, negative mentality, and inability to face reality hold him back from moving into adulthood. Holden’s immaturity causes him many problems throughout the story. Although he is physically mature, he acts more like a child. â€Å"All of a sudden I started to cry. I’d give anything if I hadn’t, but I did† (p. 103). This occurs when Maurice argues with Holden about money that Holden owes to a prostitute. The situation becomes too much for Holden to handle, and he breaks down like a child. Holden also tries to have immature conversations with people who have become adults. Another example of imma...

Langston Hughes Poems Analysis Essay

Langston Hughes purpose of these sets of poems was to outline the current condition for African Americans at that time, and also to display his desires and present the ideal conditions for African Americans. Below are several of his poems that has symbology and reflects and demonstrates his desires and ideals. In my opinion, Dream Variations demonstrates Hughes desire for African Americans to be able to enjoy the pleasures of life as white people did. When he says â€Å"to whirl and to dance till the white day is done† he is speaking of being able to be free, dancing and â€Å"flinging your arms† is demonstrative of freedom and an open expression of freedom. Then be able to rest at night and have a sense of peace of mind, knowing that African Americans have the same opportunities that White Americans experienced. In Hughes’s poem Prayer Meeting, he displays a sense of hope and longing for improvement in African Americans lives and wanted African Americans to be free from oppression. â€Å"Glory! Hallelujah! The dawn’s a-comin† demonstrates that freedom from oppression is on the horizon and that African Americans should rejoice. The setting of this poem in religion also demonstrates a sense of hope since religion is often sought after to achieve a sense of hope. In Song of the Revolution, this poem uses the symbology of the American Revolution as another call for freedom from oppression, however this is freedom from the oppression of White America. â€Å"Marching like fire over the world, weaving from the earth its bright red banner† uses fire as a symbol for hope and courage and the use of a red banner as conviction and steadfastness. In the third stanza, which states â€Å"Breaking the bond of the darker races, breaking the chains that have held for years, breaking the barriers dividing the people, smashing the gods of terror and tears† This stanza serves as a call to arms for African Americans. This stanza is less symbolic and cryptic than the others. â€Å"smashing the gods of terror and tears† is the freedom from rulers and the establishment which has wronged and oppressed them. He wants a unity of the races and a freedom and lack of oppression. In Let America Be America Again, hughes is using America’s calling as a beacon of hope to the world to demonstrates his ideal for America to truly be free and not simply as a saying. This is evident in the first stanza, which states â€Å"Let America be America again, Let it be the dream in used to be, let it be the pioneer on the plain, seeking a home where he himself is free. † The parenthesis between the stanzas is what is important, because it displays Hughes’s real opinion of America at that time, which was he doesn’t believe in America, and to him was never a beacon of hope or a land of liberty. He believes that America is tyrannical, oppressive, and discriminatory to him and his people. In the last stanza he also uses divisions of class and other races that are oppressed as reinforcement for his opinions of America. In the third stanza which states, â€Å"O, let my land be a land where Liberty is crowned with no false patriotic wreath, but opportunity is real, and life is free, Equality is in the air we breath. † It’s demonstrating Hughes’s desire for America to really be as it’s envisioned and not simply as it is portrayed (in the eyes of Hughes); equality should be as prevalent and available as air.

Slavery in Renaissance

Europe in the 14th to 16th century was marked by Renaissance. Renaissance which means â€Å"rebirth† began in Italy and later on expanded into different countries like Engalnd, France, including Germany. Within those three centuries, Renaissance reached other parts of Europe. In these years, the focus of study turned into morality of human actions rather than the usual religious issues(Encarta, 2007). It was in this era when Humanism was introduced which is based on the Philiosophy that all people are rational beings thus, everyone possesss the capacity of goodness and the truth. Furthermore, Humanism gives emphsais to the worth of an individual. While the Italian Renaissance represents the best of Europe, there are different practices that were made that conflicts Humanism. Renaissance was the same period wherein rediscovery of slavery happened (Hooker, 1996). Slavery dates back to the pre-historic times but it was in the 12th century when Human Slave Labor was rediscovered in Europe. On 1444, Portugal started to import slaves due to lack of agricultural workers while Spain followed in the 16th century and England joined the trade in the latter part of the 16th century. Hooker, 1996) Slavery was defined as an involuntary or forced form of human servitude wherein most services are obtained through force and slaves were considered as property of owner. These slaves are considered as things and they were being traded, bought, sold or payment fo0r a debt and also serve as a gift. Slaves during these times were obtained either by raid of conquest of other people wihin or from other society. During Renaissance, the fast growing Italian City-Estates demand for more slaves and was later on considered as the largest consumer of human slave. Slaves in Italy are mostly domestic servants and every wealthy family in the city have atleast one slave for household. (Hooker, 1996) While Humanists were proposing to educate the whole person of an individual, including the physical and moral development aside from intellectual achievement, a new type of slave was introduced in the purpose of economical reasons. Plantation slaves were the cheapest labor that is possible during that time. (Encarta, 2007) The existence of slavery during the Renaissance wherein the emphasis on the worth of people was highly regarded, was quite conflicting to each other but, it is evident in the accounts of Renaissance that slavery is really visible and there is a very large amount of victims of slavery. This Human Slave Trade and the presence of the â€Å"Plantation S;aves† was due to the growing needs of the plantations especially the sugar plantations for workers that will be paid in a small amount. Plantation Slave was caused by the economic stability of Italy and the growing plantations. Hence, the conflict on slavery and humanism started. (Hooker, 1996)

The Harvard University

To be what we are today, we all have our own stories to tell and personal struggles and sacrifices that we make. Some times we are just luck. Different legislators belong to different political parties so do their views, principles and backgrounds. We are going to examine two prominent personalities. First, let us look at senator Barrack Peters who is a son of an African migrant. Senator Barrack was borne forty six years ago in Illions state, his father was an African migrant who had gone in America and acquired an American citizenship then he married an American wife.As a child Barrack went to American school and performed well. He got a scholarship and proceeded to study law at the Harvard University. Where he was actively involved in students’ leadership and was the president of student union at the university. After graduating with an honors degree, Barrack worked for an American civil society group. He later joined a famous law firm called Young, Lawrence and associates w here he worked in the civil cases department. It is here that he met his wife Julia, who was working with another law firm as a clerk. After working here for ten years he left and formed his own law firm.During the same period he also got involved in politics and decided to join the democrats. His friends and wife encouraged him to go an elective position. During the next election he contested for the senator seat on a democrat ticket and was elected with a land slide. On the other hand, let us examine senator Arnold Sorio, a man who nobody imagined could be a senator. Arnold was borne fifty years ago, he was the sixth in a family of eight, his parents were very poor and his father used to work in a coal mine. The mother washed dishes in a near by hotel to supplement the father.As a child Arnold knew that everything was a struggle, he had to work as child assisting the mother in her duties at the hotel and at the same time attend school. So he went joined high school, he had to take part time jobs to pay fees as his parents could not afford to pay him. He managed to finish and joined college. In college he studied arts and drama as he loved acting and music. He had always dreamed to be an actor as this made him forget the hard times he was experiencing. After college Arnold joined a local drama group and performed in local hotels.The money he earned was very little and with pressure from his parents to assist them he couldn’t manage. Arnold decided to try his luck in Los Angles where he went. Life here become very difficult has he could not get a breakthrough to the movies where he really wanted to be. He was forced to do odd jobs to make ends meet. Two years later at thirty he got a chance to play a small role in a movie that was being shot in Los angles. The producer of the movie was so much impressed with his acting, and promised to give him a bigger role in a movie he was producing next.Soon Arnold was being sought by many film producers and he beca me a house hold name. It was with a big surprise when Arnold announced that he was quitting acting and the big screen and he is joining the Republican Party and that he was going to contest the New York seat as a senator. Every body thought what a joke an actor being a senator! But then Arnold did his home work nicely and beat his other contenders and he his now Senator Arnold Sorio. The senator is married to a former model Miss Brittney and has two beautiful daughters. These two senators have a different background and are in opposite political parties.They have different perspective of looking at national issues. Take war in Iraq, Senator Barrack believes that this war should not have happened, that American need to pull out its troops as soon as possible, as the war is draining the country resources both financial and in terms of personnel. He also reasons that this war seems not to have an end as the Iraqis themselves are not taking the initiative to end the war. The senator als o agues that the foreign polices of America should change has they have created more enmity than friendship.On the contrary Senator Arnold beliefs that the war was good for American has it removed a dictator from power. He argues that only change of regime was needed and nothing else. He also points out that American has a responsibility to bring order in Iraq and therefore the troops should stay in Iraq until order is restored. As for the resources being incurred he argues that democracy has a very big price and sacrifices must be made to gain it. When it comes to tax, Senator Barrack has a view that low income earners should be exempted from paying tax or be given tax relieves.He believes that the poor are taxed more than the rich and argue that the government should take decisive tax measures. In this way he predicts the economy will grow faster as more money will be left to the people who will then invest it. He also points out that, the living standard has shot up and yet more tax is paid; instead he proposes that the burden of tax should be reduced. On the other hand, Senator Arnold opposes the move saying that the government needs more revenue to provide services to the public.Therefore, he points out that tax relieves should not be there and instead more tax should be paid. He argues out that, for economy to grow better infrastructures and social amenities must be put in place and the government requires funds to build these infrastructures. The senator states that, good governments can only operate well when they have resources and those resources come from the people. He lastly argues that tax relieve should not be there as money that government collect in form of taxes goes back to the public in form of better services.

Erythropoietin and Athletes

Erythropoietin and Athletes Steven D. Jackson Student, American Military University Abstract Erythropoietin (EPO) use as a performance enhancing agent in sport carries both significant and detrimental risks to go along with its suggested benefits. As such, it was banned by the International Olympic Committee in 1990. Shortly thereafter, successful and reliable testing methods have been developed to test athletes for its potential use.Despite widespread knowledge of its potential adverse effects and the testing for its attempted use, EPO use remains substantial amongst endurance athletes of nearly all ages and disciplines, both professional and amateur. This paper will provide a history of EPO as a performance enhancing substance, explain its associated risks and perceived and actual benefits, attempt to analyze why athletes feel compelled to use it, and examine the sanctions, regulations, and weighty repercussions associated with its use. Erythropoietin and AthletesIn sport, there ar e a virtually limitless number of ways in which one can influence or positively impact physical or mental performance. These methods can come in the form of mechanical aids, pharmacological aids, physiological aids, nutritional aids, and psychological aids. Regardless of its source, any means by which one seeks to improve performance by enhancing the physiological capacity of a particular system of the body, removing psychological constraints which adversely affect performance, or by accelerating recovery from training or competition is called an ergogenic aid (MacKenzie, 2001).These may include something as simple and innocuous as a healthy meal consumed the night prior to a competition, but seemingly, the ergogenic aids which athletes are turning to more increasingly are those that have been banned by organizations such as the World Anti-Doping Agency, the International Olympic Committee, and the like. Often, these substances have been banned because they not only represent perver se and unethical behavior, but also, as is the case for a substance like recombinant erythropoietin, because they can have serious adverse health effects for heir users. Over time, these substances have changed, but the desire to gain an unfair competitive advantage remains. Hematopoiesis is the process which involves the production of mature cells in the blood and in lymphoid organs. Mature erythrocytes, or red blood cells, have no nucleus, so they cannot reproduce in the traditional fashion as other cells can. Erythropoiesis, then, is the process by which erythrocytes are produced. Erythropoietin is a naturally occurring hormone found within the human body which controls this red blood cell production.It is released by the kidneys, and to a lesser extent the liver, and in very little quantities in the brain in response to a negative feedback. The physiological stimulus of erythropoietin production is hypoxia, or prolonged oxygen deficiency in body tissue, and in the majority of in stances is related to the number of circulating erythrocytes within the kidneys. At high altitudes, for example, where the pressure oxygen in the air is reduced, oxygen delivery to the body’s tissues initially decreases.This drop in oxygen triggers the release of erythropoietin, which travels via the blood to the red bone marrow and stimulates red blood cell production (Shier, Butler, & Lewis, 2011). This is important to note, as this negative feedback of loss in oxygen is essentially no different than the body observing a loss in blood, which also necessitates the release of erythropoietin. In cases of hemolysis or hemorrhage, erythrocyte production will also increase rapidly and substantially for the body to attempt to accommodate for the amount of blood lost.However, overproduction of erythrocytes does not occur, both in extreme hypoxic environments and even after the most severe loss of erythrocytes (Robinson, et al. , 2006). This balance is very important, because adequa te oxygen delivery to tissues depends on having a sufficient number of red blood cells to transport oxygen. Decreases in their number or function can hinder oxygen delivery and thus affect exercise performance. Red blood cells serve a primary function of facilitating this transport of oxygen, which is bound to the hemoglobin found in red blood cells.Hemoglobin contains iron, which binds oxygen. As such, the oxygen-carrying capacity of blood is determined by its hemoglobin content. Accordingly, when hemoglobin levels fall, exercise performance is subsequently impaired. Being familiar with this, athletes, trainers, and coaches often practice iron supplementation in an effort to prevent anemia and attempt to boost hemoglobin levels. However, this supplementation cannot boost the blood’s oxygen carrying capacity beyond that which is normal.Consequently, doctors, trainers, and athletes have come up with various alternative means to try to boost blood’s oxygen-carrying capac ity, and in turn boost performance (Mottram, 2011). In traditional medical settings, the need for a means to raise red blood cell counts in patients suffering from kidney failure in order to alleviate their extreme anemia, as they have so few red blood cells that they typically experience near-permanent exhaustion. The demand for a way to treat these kidney patients precipitated the development of synthesized erythropoietin.There was no question that they needed red blood cells, and the proposition of providing them via erythropoietin seemed logically safer than the more natural and traditional repeated transfusions and dialysis. The same logic applied to the much larger number of people whose kidneys were weak or damaged, but not yet failing. Raising their red blood cell count, and subsequently their hemoglobin levels, up to a normal amount like the more attractive option, and it was only a matter of time before it could be discovered (Burch, 2011).In 1985, the gene responsible for the synthesis of erythropoietin was successfully cloned for the first time. This synthesized erythropoietin is known as recombinant erythropoietin, and first became available in Europe in 1987 and was later patented by Amgen in 1989 (Mottram). With this development, it quickly became evident that recombinant erythropoietin would be used illegally as a performance enhancer in endurance sports. As such, the International Olympic Committee elected to ban this drug in 1990, even though all forms of blood doping had been officially banned since 1984 (Robinson, et al. ).In its earliest clinical trials, recombinant erythropoietin proved very successful, and it was quickly put to use with patients requiring their hemoglobin be raised to normal levels. The trials showed the drug’s benefits outweighed its risks, but not by much. In 2005, researchers and kidney specialists concluded their trials ahead of schedule when they were stunned by what they found. After years of raising red blo od cell counts in patients to normal healthy levels, which also raised their hematocrit—the proportion of red blood cells to total blood volume—doctors were not seeing decreased occurrences of troke, heart complications, and even death. These rates were actually increasing. Therein laid the problem with EPO use, especially in uncontrolled environments and when used by athletes (Burch). Before EPO’s adverse effects were widely known, and to a great extent even today, its proposed benefits led to its immediate abuse by endurance athletes. The first cases were reported in several newspapers within the four years after recombinant EPO appeared in Europe. These articles claimed a link between rumored EPO abuse and the deaths of 18 Belgian and Dutch cyclists.This unfortunate wave seemed to roll on for some time, seemingly striking hardest amongst in the sport of cycling, and often resulting in death. For some time, cyclists publicly denied using EPO, but at the 1998 T our de France, a masseuse for the Festina team was caught with EPO and several other banned drugs. The entire team and its staff were ejected from the Tour, and eventually seven of the nine Festina riders admitted to doping. Even the winner that year, Marco Pantani, was ejected the following year for signs of EPO use in an earlier drug test (Eichner, 2007).Though the bulk of EPO use reported in the media comes from cycling, other sports are not free from it. Chinese runners, swimmers, and rowers, Russia’s top female cross-country skiers, Finland’s tops skiers, and Germany’s top runners all have been caught for suspected EPO use of some kind or another. Russian and American runners and sprinters, including American sprinter Kelli White, have been stripped of medals and handed bans for their admitted EPO use after failing drug tests.Even Lance Armstrong—who has always denied any EPO use—has been suspected of illegal EPO use brought about by claims of his former teammates (Eichner). Perhaps the greatest contributing factor for the prevalence of continued illegal EPO use is in its difficulty of detection. While some athletes may think that they are using a drug for which there is no means of detection, which is not the case, others may simply know that EPO can be a very elusive drug to detect.Early detection strategies for EPO use as a drug were limited to blood testing only. Though blood tests could confirm inconsistent hematocrit levels and other blood markers compared to base samples in athletes who may have been using EPO supplementation up to, and sometimes over, a week prior, or those that had been using EPO when they originally provided a base sample and had discontinued its use, a direct method for detection in urine had yet to be established.Furthermore, early attempts at developing a urine test proved to be expensive, overly sensitive, and unreliable. Since blood doping had been common practice in some endurance sports for decades due to its clear performance advantages, it regrettably became even more attractive once recombinant EPO became available. Athletes have exploited these limitations of testing, particularly in sports that relied solely on urine specimen testing (Robinson, et al. . Successful urine testing had finally been developed and came into the picture in 2000. Serving as the only direct method of recombinant erythropoietin detection approved by the Court of Arbitration for sport, this method utilized electrophoretic techniques to separate the isoform profiles of recombinant and endogenous erythropoietin found in urine according to their isoelectric points (Diamanti-Kandarakis, et al. , 2005).Not only could this newly approved testing mathematically and scientifically identify EPO use—or discontinuation of its use—but it could also isolate the various forms of forms of EPO, including erythropoietin alpha, beta, omega, and delta, as well as newer generations of EPO anal ogues like darbepoetin and mimetic peptides. The disadvantage of such an effective urine testing method, however, was that it discouraged athletes from recombinant EPO use. Athletes now fearful of getting caught moved back to using—or rather misusing—blood doping and transfusions in an attempt to raise hematocrit and hemoglobin levels.For that reason, some international sports federations elected to limit their testing to either blood or urine. However, more recently the trend has been to attempt to keep their current testing procedures randomized (Robinson, et al. ). The risks of illegal EPO use remain high. Some athletes choose to supplement with EPO in smaller doses with the intent of limiting their potential exposure in drug tests, and, just as likely, with the expectation that this practice would be â€Å"safer. Regardless, the results of EPO use are largely unpredictable, and tests have revealed that hematocrit values in EPO users can greatly exceed what is cons idered the healthy or normal upper limit of 50 percent. Once the hormone has been put in the body, the athlete is at great risk for substantial increases in blood viscosity. This places the individual in danger of thrombosis, myocardial infarction, congestive heart failure, hypertension, stroke, and pulmonary embolism. However, with the ever-increasing pressures to excel in competition, and the draw of larger rizes, purses, sponsorships, and notoriety in sport today it is not beyond reason as to why teams, athletes, trainers, and coaches would feel compelled to explore an option which may offer athletes a clinically documented six to eight percent increase in their VO2max and 13 to 17 percent increased time to exhaustion (Kenney, Wilmore, & Costill, 2012). Athletes who use banned EPO also risk disqualification from a particular competition, with the risk apparently greater if the athlete’s result is good, as the top-placing finishers in competitions almost certainly are subje ct to testing more and more frequently.They can also be banned from their sport, typically for a minimum of a year, but potentially for life. In their quest for enhanced performance, athletes can easily get caught up in the hype surrounding these sorts of substances and the purported benefits they might bestow. Unfortunately, too many athletes are blinded by ambition and do not consider the consequences of their actions until their careers have become jeopardized or their health has been seriously affected.Considering recent reports of even amateur athletes being dealt bans and imposed fines after testing positive for EPO use in events that are considered recreational, the need is definitely present for the likes of the World Anti-Doping Agency and the International Olympic Committee to take more aggressive and decisive action in the battle against doping and illegal drug use. The misuse of medical and biotechnological advancements to enhance athletic performance is an issue that wi ll clearly not go away on its own.It is imperative for sports federations to be able to collect blood samples from their competitors and institute a continuity system which keeps track of appropriate individual values. The appropriate way to fight blood doping and EPO use is to markers for each individual athlete to have a record of each marker and measure of their blood. In this way it will not be necessary to take into account complicating factors during testing and analysis such as sex, ethnic origin, and the kind of sport in which the athlete is participating.With a system such as this, it would be possible to identify which athletes are manipulating their bodies based on their own set reference values and markers over time. This, combined random, unannounced testing is the only way currently possible to effectively mitigate doping. Even still, it is supremely difficult for sports organizations and control agencies in sport to stay ahead of the always sophisticated doping method s. Summary Erythropoietin and all of its forms were developed with the intent of rehabilitating and alleviating the extreme symptoms of kidney patients.Their appeal is strong to competitive athletes, especially with more and more on the line each year. Despite their undeniable ability to enhance performance, EPO can cause serious negative health effects. In an era where performance-enhancing drug abuse is rampant across nearly all disciplines of sports despite rigorous legislation and testing throughout the world, it is necessary to understand the harmful effects of all substances when considering their use.The undesirable effects of EPO use are virtually countless, but—and perhaps worse yet—the potential long-term effects of chronic use are not well known.
