History of the Asian American Civil Rights Movement

During the Asian American civil rights movement of the 1960s and 70s, activists fought for the development of ethnic studies programs in universities, an end to the Vietnam War, and reparations for Japanese Americans forced into  internment camps during World War II. The movement had come to a close by the late 1980s. The Birth of Yellow Power By watching African Americans expose institutional racism and government hypocrisy, Asian Americans began to identify how they, too, had faced discrimination in the United States. â€Å"The ‘black power’ movement caused many Asian Americans to question themselves,† wrote Amy Uyematsu in â€Å"The Emergence of Yellow Power,† a 1969 essay. â€Å"‘Yellow power is just now at the stage of an articulated mood rather than a program—disillusionment and alienation from white America and independence, race pride and self-respect.† Black activism played a fundamental role in the launch of the Asian American civil rights movement, but Asians and Asian Americans influenced black radicals as well. Black activists often cited the writings of China’s communist leader  Mao Zedong. Also, a founding member of the Black Panther Party—Richard Aoki—was Japanese American. A military veteran who spent his early years in an internment camp, Aoki donated weapons to the Black Panthers and trained them in their use. Impact of Internment Like Aoki, a number of Asian American civil rights activists were Japanese American internees or the children of internees. The decision of President Franklin Roosevelt to force more than 110,000 Japanese Americans into concentration camps during World War II had a detrimental impact on the community. Forced into camps based on fears that they still maintained ties to the Japanese government, Japanese Americans attempted to prove that they were authentically American by assimilating, yet  they continued to face discrimination. Speaking out about the racial bias they faced felt risky for some Japanese Americans, given their past treatment by the U.S. government. Laura Pulido, wrote in Black, Brown, Yellow and Left: Radical Activism in Los Angeles: â€Å"Unlike other groups, Japanese Americans were expected to be quiet and behave and thus did not have sanctioned outlets to express the anger and indignation that accompanied their racially subordinated status.† Goals When not only blacks but also Latinos and Asian Americans from various ethnic groups began to share their experiences of oppression, indignation replaced fear about the ramifications of speaking out. Asian Americans on college campuses demanded a curriculum representative of their histories. Activists also sought to prevent gentrification from destroying Asian American neighborhoods. Explained activist Gordon Lee in a 2003  Hyphen  magazine piece called â€Å"The Forgotten Revolution,† â€Å"The more we examined our collective histories, the more we began to find a rich and complex past. And we became outraged at the depths of the economic, racial and gender exploitation that had forced our families into roles as subservient cooks, servants or coolies, garment workers and prostitutes, and which also improperly labeled us as the ‘model minority’ comprised of ‘successful’ businessmen, merchants or professionals.†Ã‚   Students Efforts College campuses provided fertile ground for the movement. Asian Americans at the University of California, Los Angeles launched groups such as the Asian American Political Alliance (AAPA) and Orientals Concerned. A group of Japanese American UCLA students also formed the leftist publication Gidra in 1969. Meanwhile, on the East Coast, branches of AAPA formed at Yale and Columbia. In the Midwest, Asian student groups formed at the University of Illinois, Oberlin College, and the University of Michigan. Recalled Lee: â€Å"By 1970, there were more than 70 campus and†¦community groups with ‘Asian American’ in their name. The term symbolized the new social and political attitudes that were sweeping through communities of color in the United States. It was also a clear break with the name ‘Oriental.’† Outside of college campuses, organizations such as I Wor Kuen and Asian Americans for Action formed on the East Coast. One of the movement’s greatest triumphs was when Asian American students and other students of color participated in strikes in 1968 and 69 at San Francisco State University and the University of California, Berkeley for the development of ethnic studies programs. Students demanded to design the programs and select the faculty who would teach the courses. Today, San Francisco State offers more than 175 courses in its College of Ethnic Studies. At Berkeley, Professor Ronald Takaki helped develop the nation’s first Ph.D. program in comparative ethnic studies. Vietnam and Pan-Asian Identity A challenge of the Asian American civil rights movement from the outset was that Asian Americans identified by ethnic group rather than as a racial group. The Vietnam War changed that. During the war, Asian Americans—Vietnamese or otherwise—faced hostility. Lee said, â€Å"The injustices and racism exposed by the Vietnam War also helped cement a bond between different Asian groups living in America. In the eyes of the United States military, it didn’t matter if you were Vietnamese or Chinese, Cambodian or Laotian, you were a ‘gook,’ and therefore subhuman.† The Movement Ends After the Vietnam War, many radical Asian American groups dissolved. There was no unifying cause to rally around. For Japanese Americans, though, the experience of being interned had left festering wounds. Activists organized to have the federal government apologize for its actions during World War II. In 1976, President Gerald Ford signed Proclamation 4417, in which internment was declared a â€Å"national mistake.† A dozen years later, President Ronald Reagan signed the Civil Liberties Act of 1988, which distributed $20,000 in reparations to surviving internees or their heirs and included an apology from the federal government.

The Asian Education System versus the U.S. System

According to the World Rank Research Team, Japan is at the top of industrial advances that lead to a very high amount of patents in the country (211). Japan is overtaking America in producing new inventions and conducting scientific research (World Rank Research Team 211). Producing and creating new inventions are the results of very productive, smart individuals, who had a great education throughout their school careers. The Asian education system is known world-wide for having many advantages compared to others like the United States. But they also share their own disadvantages. The United States education system is great to a certain extent, but not very efficient. According to William S. Robinson in â€Å"New Math-Science Study Rates U.S.†¦show more content†¦Japanese parents do not like seeing their children fall behind in school, and they go to an extreme level of parenting which is a main key point of stress onto their children. Fallows uses a quote â€Å"Pass with four, fail with five† referring to the amount of hours their children should sleep (204). Four hours of sleep lets the student have more time to study than five hours of sleep. Extreme levels of parenting lead to excessive pressure on their children, and many teachers and parents â€Å"complain bitterly† about their education system, but little is done to change it (Fallows 204). Pressure on students may lead to stress and depression that can change their lives forever. It can affect teenagers, and young adults by encouraging them to do illegal things such as drinking, smoking, and doing drugs because pressure would change their behaviors, attitudes, and even their morals. Besides all the negativity, the United States and Asia have advantages that make them different from one another. The United States education system may not be efficient enough, but there are also advantages of having the system we have now. The main advantage America has in its education system is freedom. Having the freedom in class to speak and express our opinion is very important in the American culture. Such as, speaking out loud and being free to give an opinion in class.

Lao Tzu Essay Example For Students

Lao Tzu Essay Born in the Chinese province of Henan, Lao Tzu lived from c. 604-c.531 BCE. He was a philosopher attributed with the writing of the Tao-Te-Ching and the reputed founder of Taoism. (Tao meaning the way of all life, Te meaning the fit use of life by all men, and Ching meaning text.) Lao Tzu was not his real name but rather an honorary title given to him by his followers meaning Old Master. Lao Tzu believed that human life is constantly influenced by outer forces; not unlike everything else in the universe. He knew that simplicity was key to all truth and freedom. He always encouraged those who followed him to observe and to seek to understand the laws of nature. Lao Tzu believed that one should develop intuition and build up personal power, which would then be used to lead life with love sans force. As he often contemplated the natural world, Lao Tzu felt that it was man and his doings that created an affliction on the otherwise flawless order of things. Thus he counseled his followers to turn away from the silliness of human pursuits and to return to their na tural wellspring. Lao Tzu taught that straining and striving are not only useless but also counterproductive. One should venture to do nothing in the sense of discerning and following the natural forces; to follow and shape the natural flow of events. All this is known as the Taoist doctrine of wu-wei. It can be understood as a way of mastering circumstances by understanding their nature and then shaping ones actions to comply. The Taoist philosophy followed an interesting circle. On one hand, that Taoists rejected the regulation of life and society and preached instead to turn away from it to a solitary meditation of nature. On the other hand, they believed that by doing this one could ultimately have power enough to harness the whole universe. That by doing nothing one could accomplish everything. In this way Lao Tzus philosophy reached out to political rulers and advised them of how to govern their land. Thus Taoism, in a sense became a sort of political philosophy following these lines: The Taoist has no ambitions, therefore he can never fail. He who never fails always succeeds. And he who always succeeds is all-powerful.According to legend, nearing the end of his life, Lao Tzu set off into the desert toward what is now Tibet, sadden and disillusioned that men were so unwilling to follow the path to natural goodness. When he arrived at the final gate at the Great Wall of China, the gatekeeper convinced Lao Tzu to record his teachings and the principles of his philosophy before he left. He then composed in five thousand characters, eighty-one sayings that make up the Tao Te Ching. This ancient Chinese text is the most translated classic worldwide next to the Bible. From his solitary contemplation of nature, removed from human affairs, Lao Tzu conjured a philosophy that has, both in critical as well as a constructive sense, a direct and practical political message:Why are people starving?Because the rulers eat up the money in taxes. Therefore the people are starving. Why are the people rebellious?Because the rulers interfere too much. Therefore they are rebellious. Why do people think so little of death?Because the rulers demand too much of life. Therefore the people take life lightly. Having to live on, one knows better than to value life too much. -Lao Tzu_Words/ Pages : 642 / 24

Marketing Boards Essays - Marketing Board, Agricultural Cooperative

Marketing Boards Introduction Marketing Boards are government involved ways of regulating farmer's production and price, while protecting the overall profit of every farmer in that particular production. Since there is nothing farmers can do about the inelastic nature of the demand for farm products, the key to supporting and stabilizing farm prices and incomes lies in controlling the supply of farm products. In other words, farmers would benefit greatly from an oligopolistic (banning firms together) price and supply agreement among themselves. Farming is a highly competitive industry ? it consists of many small, independent producers selling substantially similar products in a big marketplace. Given these realities, it has proven very difficult to achieve any kind of agreement or coordinated action on the part of farmers, even when it would be in their best interest to do so. Attempts have been made to use farm cooperatives to restrict production and thus support and stabilize prices; however, these efforts rarely work. Such agreements are voluntary and lack means of enforcement; as a result, too many farmers don't participate or break the agreements. This is when farmers turned to government assistance to help with their low and unstable incomes and marketing boards was proposed. In the following we will discuss what marketing boards are, how they work, how they effect the Canadian economy, and how widespread they are. We will focus on particular Canadian producers who use marketing boards and how they are both positive and negative in contributing to the economy. We will also look at how marketing boards are effecting the consumers. In total outlook, the purpose of this review is to provide a clear and explicit focus for the research to be undertaken as well as to establish the scope of the study.

“The Moment” by Margaret Atwood and “London” by William Blake Essay Example

â€Å"The Moment† by Margaret Atwood and â€Å"London† by William Blake Essay Both â€Å"The Moment† by Margaret Atwood and â€Å"London† by William Blake are poems about man’s relationship and dependency on nature. They both teach the message that you need to embrace nature to survive as a human; and warn against the consequences of not doing so. Where Atwood’s poem is more of a warning about what could happen if we reject nature, Blake let’s us experience what this is actually like, he describes humans trying what Atwood has warned against.The tone of the poems is very different. Blake’s tone could be described as morbid, oppressive and disillusioned with words like â€Å"woe† and â€Å"blackening,† where the tone of Atwood’s poem is clearer and more didactic, more suited to delivering the political message it aims to, and less personal than Blake’s narrative poem. There are elements of a misanthropic nature in both poems. Atwood’s poem seems to be quite mocking of the human race, s howing how oblivious we are to what we are bringing upon ourselves, with the line â€Å"house, half-acre, square mile, island, country† sounding somewhat like a politicians speech. Blake is very bitter and condemns man in his outcry against the industrialisation of London.Both poets use equal stanzas and rather simplistic language in their poems. For Atwood, this is to deliver her message to as many people as she can. Blake’s poem takes on a song-like quality and he creates this nursery-rhyme feel to show how purity can be corrupted through experience, in the way he uses tabula rasa in his â€Å"new-born infant† who is already a hindrance to his â€Å"harlot† mother.The poems slightly contradict each other in their idea of what being in sync with nature is and what it is exactly which makes you fall out of sync with nature. Atwood says that the struggle and â€Å"hard work† to have more, achieve more and be more is human nature, and makes us one wi th nature and living alongside it. However, the moment we â€Å"at last† stop struggling and sit back to admire our wealth, saying â€Å"I own this† is the moment nature rejects us. On the other hand, Blake shows this struggle in the industrialisation of the city and this does not seem in sync with nature at all. Both poets agree on the fact that in trying to control nature, nature can destroy us; we cannot live without it. They show this through a change of pace and rhythm. In â€Å"The Moment† the building pace of stanza one is broken by â€Å"I own this.† This breaks the natural pace of the poem, showing how humans have upset the natural flow of life.Blake also uses this idea in his change of rhythm from the first to second stanza, showing how, due to human actions, the natural rhythm of life has changed, in the same way the natural rhythm of the poem does; what we are doing is not natural. Atwood uses rhythm in her second stanza to warn against challe nging nature. She tells how the â€Å"trees will unloose their soft arms from around you† and the â€Å"air will move back from you.† This whole stanza has a feel of things moving backwards like a tape in rewind. Time moves forwards, unlike in this stanza. Here, Atwood is using Blake’s idea of how this behaviour is unnatural. Atwood is also telling us how we can’t survive without nature; we need â€Å"air† to breathe. The last line â€Å"and you can’t breathe,† breaks the flow of the poem, making you take a breath. This almost replicated the action of gasping for air. Blake also warns against trying to break away from nature, he describes a city full of misery and â€Å"woe.†Although Atwood focuses more on how nature will reject us and the consequences of nature, where Blake talks more about human suffering and human consequences, with more manmade references, poet poets use the idea of trying to control nature. Blake uses oxym oron’s to show this. The ideas of â€Å"wandering† through a â€Å"chartered† street and a â€Å"chartered† river which is â€Å"flowing† seem to contradict themselves. â€Å"Chartered† implies carefully measured and controlled, but in reality, man cannot ever charter a free and â€Å"flowing river,† a part of nature. Where Atwood writes in blank verse and in a much more free nature, with a constantly changing pace, to show the lack of control we have over nature, Blake’s structure is much more restrictive. He uses an alternate line rhyme and a strong iambic pentameter comes through in â€Å"in every cry of every man, in every infant’s cry of fear.† This strong metre creates a relentless pace, and conveys an idea of confinement and being trapped, due to the set form, mirroring the â€Å"chartered† lives of the cities inhabitants after they have tried to control the nature surrounding them.Although nature co mes across a lot stronger in Atwood’s poem, in the way she gives nature its own voice saying â€Å"we never belonged to you,† both poets use the idea of mass to create strength. In â€Å"The Moment,† Atwood uses the exclusive pronoun â€Å"they whisper,† putting nature in the plural. Blake also uses this idea in the use of â€Å"every† voice, to show the wide-spread, and strength of the misery in the city due to man.Both Atwood and Blake make use of repetition. Atwood does this in the repetition of â€Å"the moment,† first to show the human perception of the situation, and secondly to show the reality of it, highlighting the stupidity of man. Blake does this in his repetition of â€Å"every cry.† This use of anaphora is a declamation to be heard, reminding readers of what they would rather not admit to and emphasising the idea of no escape. Both poets also effectively use onomatopoetic techniques. In â€Å"London,† Blakeâ€℠¢s use of the plosive /b/ in â€Å"ban† â€Å"blasts† â€Å"blackening† â€Å"blood† â€Å"new-born† and â€Å"blights† explodes from the lips to join the crying and cursing on the London streets, making the poem quite sensory and allowing the reader to actually experience â€Å"London.†In the second stanza of â€Å"The Moment,† the sounds start from a soft /s/ and gradually build up through a harsher /b/ to a sinister ‘hissing’ sound in the alliteration â€Å"cliffs fissure and collapse.† This reflects the worsening of the damage nature will cause and how humans will carry on until it is too late. Blake also uses an alliteration in â€Å"mind-forged manacles,† reinforcing the idea that this misery, or impending misery in Atwood’s cause, is entirely self-inflicted by humans. â€Å"Mind-forged† gives the idea that people are trapped by their own actions, and are possibly so brainwashed by the authorities striving for the glory of industrialisation, that even though they see themselves as helpless, they do not even consider the possibility of rebelling. This also has a sense of a loss of freedom and free will.The main feeling, I believe, conveying in both poems is blame on humans for our actions and the idea of a need for change soon before we have to face the consequences.

Everybody Speaks Hamlet

Everybody Speaks Hamlet Everybody Speaks Hamlet Everybody Speaks Hamlet By Maeve Maddox Someone once said that every generation has its favorite Shakespeare play. Hamlet was a favorite with the Victorians. Macbeth enjoyed a great popularity in the first half of the 20th century; Othello in the second half. It seems to me that King Lear may be the play that will come to be associated with the early 21st century. Whatever the general trend, Hamlet is always near the top of Shakespeare favorites. As a result, quite apart from the famous To be or not to be and What a work is man soliloquies, many of the speeches, lines, and phrases have become embedded in our everyday speech. English speakers who have never read the play or seen it acted are likely to use one or more of the following expressions or some form or another: To thine own self be true Though this be madness, yet there is is method in t.

Cameron Mackintosh's contribution to the development of the Essay

Cameron Mackintosh's contribution to the development of the megamusical - Essay Example This paper further highlights the legacy of Mackintosh’s transformation of musical theatre through the increasing importance attached to the marketing of megamusicals; which in turn has fuelled debate as to the repercussions of the megamusical for the musical as an art form as opposed to a corporate controlled money spinner. In considering Mackintosh’s contribution to the megamusical, it is imperative to consider the contemporary framework for the business of theatre production in London’s West End and Broadway. For example, if we contextually consider the theatre market in the West End, recent hit shows from the Sound of Music to Joseph have driven the reversal in fortune of West End theatres, which had suffered a trend in declining ticket revenue and profits in the last decade. In January 2008, the Society of London Theatre announced a record breaking year in 2007 with more than 13.6 million theatregoers generating total tickets sales of almost  £470 million, passing the  £400 million mark for the first time. Furthermore, the Society’s Chief executive Richard Pulford cited the revenue statistics as an â€Å"annus mirabilis† for London theatre, stating that â€Å"these figures are a wonderful start to our centenary year but we’re under no illusions that we’re going to have to work very hard to maintain this success† (Maev Kennedy., 2008).

Hamlet essay Example | Topics and Well Written Essays - 1000 words - 2

Hamlet - Essay Example The complexity of action as well as the impossibility of certainty is prominently highlighted when it comes to discussing the execution of revenge by Hamlet, the protagonist in Shakespeare’s Hamlet. The lack of self-confidence and hindrance of inaction of the protagonist distinguishes the play remarkably apart from other revenge plays in English literature. Shakespeare portrays Hamlet as an able yet reluctant hero who is characteristically more prone to apprehension than to action. This is the case of his dilemma: of realizing the truth behind his father’s murder followed by the ghostly encounter, of acknowledging the plan of revenge and yet choosing to postpone this action. This thin demarcation between action and inaction is prominently expressed in the innermost thoughts of Hamlets, what is more appropriately known as Hamlet’s soliloquies or his self-conversation. Among the soliloquies of Hamlet in the play, the most debated one expressing the protagonist’s innermost projections is the â€Å"To be or not to be† soliloquy from Act III, Scene I of Hamlet. It most undoubtedly holds the central place of the entire discussion of action and inaction on the part of the protagonist for planning his ‘revenge’. Indeed the soliloquies speak of more action than does the protagonist himself. In Davies’ (2008) words, â€Å"Hamlet is rarely more dynamic or on the move as a character than in the action of his soliloquies, which remain the vehicles for an unfolding ‘drama of thought’ throughout Hamlet rather than expressions of a fixed kind of ‘dramatized thinking’. In soliloquy, we have the Hamlet who is ready ‘to drink hot blood’ in Act III, Scene II, and yet who refuses to kill Claudius in Act III, Scene III; who knows not why he lives ‘to say this thing’s to do’ in Act IV, Scene IV, but even at this most hopeless point, implicitly recognizes that

Thus, the mission statement defines the specific strategies that are to be undertaken to ensure that the vision is achieved. Values play a crucial role in the vision and mission of an organization. The beliefs, principles, and philosophies of the officers and leaders in the organization influence the manner by which vision and mission statements are designed. As emphasized, â€Å"vision and mission statements should articulate the essence of your organizations beliefs and values and define its place in the world† (Foundation Center, 2015, p. 1). Likewise, core values are further asserted as the â€Å"the principles and standards at the very center of our character, and from which we will not budge or stray.

Foreign Exchange Risk Management In Multinational Corporations Finance Essay

Foreign Exchange Risk Management In Multinational Corporations Finance Essay Corporations (MNCs) Introduction: Globalisation has had economic, cultural, technological and political effects. Over the last few decades the increase in globalisation has led to rapid growth in several industries around the world and it has also had a strong influence on the flexibility of firms. Hundreds of new MNCs have emerged globally due to the liberalisation of trade and capital markets. MNCs are not limited to the big firms with huge investments like Coca Cola, Nike and Shell, due to advances in technology and liberal markets many small firms operate internationally to maximise their profits. This growth has highlighted the various risks faced by MNCs operating in different countries. One such risk is the financial risk involved with the foreign currency exchange markets. Most of the time MNCs deal in more than one national currency and hence the changes in the foreign exchange rates can have an adverse effect on the firms profits. This paper discusses the various foreign exchange risks faced by multinationa ls around the globe and the necessary steps taken to manage these risks. A study on the Malaysian MNCs has also been covered in the paper. Foreign Exchange Risks: Foreign Exchange risks also known as exposures can be termed as an agreed, projected or contingent cash flow whose scale is not certain at the moment. The magnitude depends on the value of the changes in the foreign exchange rates which in turn depends on various variables such as the interest rate parity, purchasing power parity, speculations and government policies on exchange rates. According to G.Shoup (1998), a company has exposure if there is a currency mismatch in some aspect of the business such that a shift in foreign exchange rates, nominal or real, affect its performance either positively or negatively. These exposures may be classified into three different categories: Translation exposure Transaction exposure Economic exposure Translation Exposure; this is the net asset/liability exposure in the home currency of the MNC. In other words, it is the profit gained or loss incurred in translating foreign currency financial statements of foreign subsidiaries of the MNC into a single currency which it uses in its final reports (Yazid Muda, 2006). In essence, translation risk can be defined as the effect of exchange rates on the figures shown on the parent companys consolidated balance sheet. Although this exposure does not affect the shareholders equity, it does influence the investors due to the changing values of the assets or liabilities. (Shoup, 1998) Transaction Exposure; it is a risk associated with a transaction that has already been contracted. It is as a result of unexpected changes in foreign exchange rates affecting future cash flows which the MNC has already committed itself to. Usually MNCs enter an international contractual obligation, the payment or receipt of which is expected on a future date, hence any change in the foreign exchange rate during that period will expose the MNC to transaction risks. Transaction risks can be easily identified and thus get more attention from the financial managers. (Eiteman, Stonehill, Moffett, 2007) Economic Exposure; this is the most complex risk as it not only involves the known cash flows but also future unknown cash flows, hence also termed as a hidden risk. It is a comprehensive measure of a companys foreign exchange exposure and therefore sometimes termed as a combination of translation and transaction exposure. Identifying economic risks involves measuring the change in the present value of the company resulting from any changes in the future operating cash flows of the firm caused either by adverse or desirable change in the exchange rate. (Eiteman, Stonehill, Moffett, 2007). As Dhanani (2000) noted, economic risk can be viewed as the consequence of long-term exchange rate fluctuations on a firms predicted cash flows and as the cash flows linked to the risk are not certain to materialize, the risk is hard to identify. Economic exposure to a MNC may last for a long duration making it difficult to be quantified and hence limiting the use of possible management techniques. (Shoup, 1998) Foreign Exchange Risk Management Foreign exchange risk management is a process which involves identifying areas in the operations of the MNC which may be subject to foreign exchange exposure, studying and analysing the exposure and finally selecting the most appropriate technique to eliminate the affects of these exposures to the final performance of the company. (Shoup, 1998) Risks involving short term transactions can be dealt with using financial instruments but long term risks often require changes in the operations of the company. As in the case of translation exposure the MNC can have an equal amount of exposed foreign currency assets and liabilities. By doing so the company will be able to offset any gain or loss it may have due to changes in the exchange rates of that currency, also known as balance sheet hedging. (Eiteman, Stonehill, Moffett, 2007) In dealing with economic exposures efficiently, a MNC may have to diversify either its finance or its operations. It can diversify its operations by either moving to locations where the cost of production is low, or having a flexible supplier policy, or changing the target market for its products and the types of products it deals in. As it can be illustrated from the 1994 example of Toyota, when a strong Yen made Japanese exports to US more expensive, it decided to shift its production from Japan to US, where it achieved comparatively lower costs of production, enabling it to compete in the US car market. (Eun Resnick, 2007) The management of transaction exposures may either involve hedging using special techniques or applying pro-active policies. The pro-active policies commonly used include (Eiteman, Stonehill, Moffett, 2007): Matching currency cash flow Risk sharing agreements Back to back loans Currency swaps Lead and Lag payments Use of re-invoicing centres Hedging is the act of protecting a pre-existing position in the spot market by trading in derivative securities; that is guarding of existing assets from future losses. According to Eiteman et al (2007), hedging is the taking of a position, acquiring a cash flow, an asset or a contract that will rise or fall in value and hence offset a fall or rise in value of an existing position. Several studies on this issue have emphasized that MNCs have a higher probability of facing exchange rate volatility in their operations as they expand their involvement throughout the world. Therefore, the extensive use of various hedging techniques by most companies has been widely recognized to ensure the companys overall interests, cash flows and equity are safeguarded. Some of the most commonly used hedging techniques include: Forward market hedge Money market hedge Options market hedge Forward market hedge; this is the case where the MNC in the forward contract has a legal obligation to buy or sell a given amount of foreign currency at a specific future date which is known as the contract maturity date at a price agreed upon at present. (Nitzche Cuthbertson, 2001) Money market hedge; under this hedging technique, the transaction exposure can be hedged by lending and borrowing in the local and foreign markets. For instance a MNC may borrow in a foreign currency to hedge the amount it expects to receive in that currency at a later date and similarly it could lend to hedge payables in a foreign currency. By doing so, the MNC will be matching its assets and liabilities in the same currency. (Eun Resnick, 2007) Options market hedge; this is a technique used by a MNC which gives it the right but not the obligation to buy or sell a specific amount of foreign currency at a specific price, by or on a specific date. Although not a widely used tool, it can be useful when a MNC is uncertain about the future receipt or payments of foreign currency. (Nitzche Cuthbertson, 2001) Hedging helps in reducing the risks involved in international transactions and also improves planning capability. By hedging a MNC can ensure its cash flow does not fall below a necessary minimum, particularly in cases where there is a tendency of a company to run out of cash for necessary investments (Eiteman, Stonehill, Moffett, 2007). A very good example would be that of Merck, a pharmaceutical company. Kearney and Lewent (1993) identified that Merck was one of the pioneers to have used hedging to ensure that its key investment plans could always be financed, which in their case was the research and development aspect of their business. Mathur (1982) came to the conclusion that, to decrease the negative outcomes caused by fluctuations of foreign exchange rate on earnings and cash flows, most companies employ a hedging program. He also noted that a formal foreign exchange management policy is more common among larger firms. According to Bartov et al (1996), if MNCs do not institut e a hedging program, they are more likely to be exposed to risks which may result in substantial losses. Despite its advantages, hedging does not increase the companys expected cash flows, on the other hand it uses up the company resources in the process (Eiteman, Stonehill, Moffett, 2007). According to G.Shoup (1998), unless there are clear defined objectives, safeguards in place and clear communication at every level of management, a hedging program may turn into a disaster. As the chairman of Zenith Electronic Corporations, Jerry K Pearlman once said, It is a, damned if you do and damned if you dont situation. (Shoup, 1998, p15.) In 1984, Lufthansa a German airline company placed a major purchase order for airlines from an American firm. The financial managers at Lufthansa had forecasted a stronger dollar in the days to come and therefore locked up the German Duetsche mark against the American dollar. Due to an unfavourable effect, a weak dollar, in one year Lufthansa lost around US$150 million and half of the financial managers team lost their jobs (Shoup, 1998). In another instance, two years later in 1986, the chairman of Porche found himself unemployed as he had engineered the company into a dependence on the US market for 61% of its revenue without hedging against a downturn in US$, as a result forcing Porche to suffer major financial losses. (Shoup, 1998) According to a study by Marshall (2000), the trend in the objectives of managing foreign exchange risks was quite similar between the UK and US multinationals who gave significant importance to certainty of cash flow as well as minimising fluctuations in earnings. On the other hand, a higher number of Asian multinationals managed these risks to minimise fluctuations in their earnings. The trend observed is summarised in Figure 1 below. Figure 1: Foreign exchange risk management in UK, USA and Asia Pacific multinational companies by Andrew P Marshall, Journal of Multinational Financial Management, 2000. Belk and Glaum (1990) undertook a study which involved investigating several UK MNCs. The study revealed that although majority of the companies considered translation exposure to be important, not all were prepared to hedge this risk actively. On the other hand transaction exposure was given most importance in the management of foreign exchange risks. The level of hedging the transaction exposure varied between the companies investigated, some hedged totally while others did so partially. The study also seemed to show that the size if the MNC influenced its involvement in foreign exchange risk management, the larger the company the higher the propensity. In another study carried out by Makar and Huffmann (1997), it was found that there is a linear relationship between the amount of foreign exchange derivatives employed and the degree of foreign currency exposure in US MNCs. Foreign Exchange Risk Management in Malaysian Multinational Corporations (MNCs) During the financial crisis of 1997, most Malaysian MNCs suffered foreign exchange losses due to currency fluctuations, thus leading to the increased involvement of Malaysian MNCs in foreign exchange risk management (Yazid Muda, 2006). It can be seen that before the financial crisis fewer MNCs considered hedging their foreign exchange risks to be vital, as the General Manager of the Malaysian Monetary Exchange Bhd indicated that local MNCs were very passive and reactive in managing their financial risks (New Strait Times, 30 May 1998: 11). A similar statement was given by the then Minister for International Trade and Industry, Rafidah Aziz, which implied that MNCs should manage their foreign exchange risks well (New Strait Times, 3 July 1998). A very good example of the losses suffered would be that by Malaysian Airline System (MAS), MAS lost around M$400 million in the first half of 1998 because of its foreign debt of about M$3.16 billion. Yazid and Muda (2006) studied 90 out of th e then 113 MNCs listed under the Bursa Malaysia. The main objectives cited by MNCs in this study relating to the foreign exchange risk management were to minimise the following; Losses on operational cash flow Cash flow fluctuations Losses on consolidated balance sheet Losses on shareholders equity Business uncertainty Foreign exchange risk to a comfortable level According to Yazid and Muda (2006), Malaysian MNCs became very proactive in managing their foreign exchange risks during the financial crisis and once the crisis was over, the priority attributed to foreign exchange risk management decreased slightly but not to the point it was before the crisis. This has been illustrated as a summarised result of the survey shown in table 1. Objectives Before During Current Minimise Losses on operational cash flow 3.59 4.62 4.09 Minimise Cash flow fluctuations 3.29 4.41 3.88 Minimise Losses on consolidated balance sheet 3.26 3.91 3.82 Minimise Losses on shareholders equity 3.24 3.56 3.50 Minimise Business uncertainty 3.21 3.50 3.41 Minimise Foreign exchange risk to a comfortable level 2.91 3.53 3.29 Table 1 (Yazid and Muda, 2006) Note: The results are based on five-point progressive Likert scale (1 is the least important; 5 is the most important) Large MNCs in Malaysia are more likely to get involved in foreign exchange risk management compared to smaller firms or firms with relatively lesser operations outside Malaysia. This trend seems to be consistent with other MNCs around the globe (Yazid et al, 2008). Majority of the Malaysian MNCs centralise their foreign exchange risk management and it can be said that foreign exchange risk management in Malaysia is still at its infant stage in comparison to other MNCs in the west. Their management practices are very informal and no proper documented policies can be found in regard to foreign exchange risks. Although the use of hedging tools is on a steady rise amongst the Malaysian MNCs, the objectives behind their involvement remain uncertain (Yazid and Muda, 2006). The past decade has seen rapid growth of a new segment in the global finance industry, the Islamic finance sector. To qualify for Islamic foreign exchange hedging, transactions must involve tangible assets. Malaysia, which is pre-dominantly an islamic country has highlighted the need of hedging tools which are compliant with Islam. Hence CIMB, a leading Malaysian bank among others, have introduced an Islamic foreign exchange hedging instrument, which would assist their clients to manage their risks. (Reuters, 2008) Astro, which is a leading services provider in the Asian entertainment indutry is based in Malaysia. Being a MNC, foreign transactions are dealt in different foreign currencies other than the Malaysian Ringgit. Consequently, there is an exposure to foreign currency exchange risk. Astro uses foreign currency derivatives such as forward contracts and interest rate swap contracts to hedge currency exchange risks. Forward contracts are commonly used to limit exposure to currency fluctuations on foreign currency receivables and payables as well as on cash flows generated from anticipated transactions denominated in foreign currencies. In 2007 Astro made a loss of RM 137,000 due to foreign exchange fluctuations and henceforth decided to emphasize the use of hedging techniques. This can be proven by Astros estimated principal amounts of outstanding forward contracts which as at 31st January 2009 was RM188,083,636, whereas at the same time a year before it was at RM 5,109,000. The emphasis o n risk management resulted in a substantial gain of RM 7,680,000 for Astro in the year ended 2008. In addition, as Ringgit Malaysia is Astros functional currency; all the financial statements have to be consolidated into this currency. Hence Astro is exposed to translation risk due to the fluctuating exchange rates. According to Table 2.0, the significance of the foreign currency risk management is noticeable as Astro experienced a huge gain in 2008 relative to the loss they suffered in 2007. Table 2.0: ASTRO; Result of Foreign Exchange Risk Management Cash Flow due to Operating Activities 2008 RM000 2007 RM 000 Net Effect of Currency Translation on Cash and Cash Equivalents 4854 (1529) Gain on Realisation of Foreign Forward Contracts 7680 (137) However, hedging of foreign exchange does not always yield a positive result, as illustrated in the case of AirAsia, one of the leading budget airlines in Asia. AirAsia like many international airlines used a technique refered to as fuel hedging, this allows the airline to purchase fuel at a price fixed at an earlier date despite an increase in the fuel price. During the fuel crisis of 2007-2008 when prices rose to over US$150/barrel, AirAsia made a significant loss as it had hedged for fuel prices not to exceed US$90/barrel and as a result AirAsia recorded its first ever full year loss of RM471.7 million for the year ended 31st December 2008, despite achieving a growth of 36.6% in revenue. This led to the removal of all hedges on fuel prices and AirAisa declared itself as completely unghedged. Although AirAsia intends to re-introduce fuel hedging in 2011, for now it deals in spot prices for its fuel. (Leong, 2009) (Ooi, 2008) Conclusion Multinationals are exposed to various kinds of risks, which includes the foreign exchange risk. This risk which is as a result of exchange rate volatility is said to have a pervasive impact on the profitability and certainty of a MNC. Globally, multinationals face translation, transaction and economic risks due to the frenzied system of floating exchange rates. To avoid the adverse effects of these risks, multinationals often take measures which although do not entirely eliminate the losses; they do enable the firms to minimize the losses. Hedging is very common risk management tool used by multinationals and has often resulted in positive results when used after a correct analysis of the exposure is made. Despite its advantages, not all multinationals around the globe decide to manage their risks in this way. The objectives behind foreign exchange risk management and the techniques used to manage are seen to differ across regions. In the case of Malaysian multinationals, foreign exchange risk management is deemed to be at a lower level relative to their counterparts globally. Until recently, majority of the Malaysian multinationals were not actively managing these risks. The Asian financial crisis in the late 1990s had a significant effect on their stance and the level of foreign exchange risk management amongst Malaysian multinationals has since increased considerably.

Positive and negative effects of legalizing drugs on the United States economy

The perennial problem of drug abuse has always been a controversial one since questions arise whether a sovereign entity is justified in attempting to curtail personal choice in the question of whether to engage in drugs or not.Opponents of drug use argue that a state has an obligation to protect its people against destruction even though the means to such an end is voluntary since it is generally accepted in accordance to the natural laws that all people have a right to life.Proponents of drug legalization have been quick to point out that human will, cannot be suppressed and it is economically futile to attempt to do so and hence it would be in the states interest to allow those in favor of such a course to indulge without interference. However, there are several moral, health and religious factors that have hindered those in power to actually consider legalizing illegal drug use since such recourse would raise fundamental ethical issues regarding their leadership as directed by th e constitution.Reasons for legalizing drug useThere are several reasons that have led some to clamor for the legalization of drug use. Firstly there are those who feel that the question of drug use is essentially related to personal freedom and that essentially competent adults should be left to decide for themselves if they wanted to engage in self destruction or not. It is not surprising then that some have argued that by the very nature of the state restricting drug use and in addition prosecuting users, the state is contravening the very constitution created to be its guide.Secondly, the United Sates uses a lot of tax payer’s money in their fight against drug use. Enforcement agencies are forced to recruit more personnel in their mandate to find drug traffickers and drug users. These law enforcers need to be remunerated when in active service and in addition are entitled to several benefits during their active service and in their retirement.This tends to make the federal and state government to divert huge funds towards operations of these enforcers and in the wages of their personnel. This in turn leads to shortages in funds which could have been channeled to other development agendas.The economical cost of combating   drug abuse does not end with the police but goes on to necessitate more expenses to be provided for the prosecution of these individuals and also to cater for those charged with the duty of deciding the fate of these supposedly law breakers.As drug consumption increases it leads to a need to hire more prosecution personnel and to avoid a backlog of cases more magistrates are hired to listen and pass sentences. This increases a burden to the tax payers and questions arise as to whether people should essentially pay for the negative choices of competent individuals. Furthermore, most people in American correctional facilities have been put there for drug related offences.The cost of maintaining a prisoner is quite high and it is the refore economically realistic to legalize drugs as a way of reducing expenses and therefore use it as a tool of lessening the budget deficits and to provide more funds to important sectors in the economy (Goode, 97-150).The fight against drug abuse has put America at a collision course with several countries perceived to be supplying drugs to the United Sates. Legalizing drugs would end this hostility improving bilateral relations with those countries and expanding markets for American products and allow investors to work easily in those countries (Friedman, 2009).In addition legalizing drugs would allow for the investment of several billions of drug money in other businesses to help expand the economy, provide employment and reduce other crimes.

Bibilography Abstract: Mobile devices are getting smaller, lighter, and more powerful; they have bigger screens and longer battery life, more features and more capabilities. Things like watching the football game on your mobile device, watching movies, videoconferencing, paying your bills and downloading music to the palm of your hand will become second nature in the near future. Bandwidth will always be the limiting factor in the development of applications and devices, be it wired, or wireless.At the moment the wireless world doesn’t have a large-cell, high bandwidth standard, that is capable of delivering the much needed speeds to a mobile device. The short fall of 3G networks is clear, it’s just not fast enough, offering 384kbps doesn’t meet the requirements of what the end user has come to expect these days. Some people see 3G as a stop-gap, until a fully integrated IP network is created; some countries have even chosen to bypass 3G and head straight to 4G, a method which has its advantages, and its disadvantages. G is set to be available around 2010, getting it right first time will make it a general winner with the one billion mobile users around the world. The end user can expect low cost per data bit, as well as speed and reliability, something which is greatly. Technology Companies with 4G networks are knocking on the door and mobile operators are beginning to answer. 4G networks and Next Generation Netwo rks (NGNs) are becoming fast and very cost-effective solutions for those wanting an IP built high-speed data capacities in the mobile network.IP is pushing its way into the mobile wireless market,† said Visant Strategies Senior Analyst Andy Fuertes, author of â€Å"The Road to 4G and NGN: Wireless IP Migration Paths. † By 2010, the just-published study finds, there will be 113 million NGN and 4G users, with the market starting to take effect 2006 and 2007. Introduction: 4G is an initialize of the term Fourth-Generation Communications System. †¢ A 4G system will provide an end-to-end IP solution where voice, data and streamed multimedia can be served to users on an â€Å"Anytime, Anywhere† basis at higher data rates than previous generations.No formal definition is set as to what 4G is, but the objectives that are predicted for 4G can be summarized as follows †¢ 4G will be a fully IP-based integrated system of systems and network of networks wired and wi reless networks (e. g. : computer, consumer electronics, communication technology†¦) †¢ Providing 100 Mbit/s and 1 Gbit/s, respectively, in outdoor and indoor environments †¢ End-to-end quality of service †¢ High security †¢ Offering any kind of services anytime, anywhere †¢ Affordable cost and one billing †¢   The following are some possible features of the 4G systems : Support interactive multimedia, voice, video, wireless internet and other broadband services. †¢ High speed, high capacity and low cost per bit. †¢ Global mobility, service portability, scalable mobile networks. †¢ Seamless switching, variety of services based on Quality of †¢ Service (QoS) requirements †¢ Better scheduling and call admission control techniques.

There are three possible architectures for 4G. †¢Multimode devices †¢Overlay network †¢Common access protocol. Multimode devicesThis architecture uses a single physical terminal with multiple interfaces to access services on different wireless networks. It may improve call completion and expand effective coverage area. It should also provide reliable wireless coverage in case of network, link, or switch failure. The user, device, or network can initiate handoff between networks. The device itself incorporates most of the additional complexity without requiring wireless network modification or employing inter working devices. Each network can deploy a database that keeps track of user location, device capabilities, network conditions, and user preferences. Figure-1 The handling of quality-of-service (QoS) issues remains an open research question. Overlay networkIn this architecture, a user accesses an overlay network consisting of several universal access points. These UAPs in turn select a wireless network based on availability, QoS(Quality of Service) specifications, and user defined choices. A UAP performs protocol and frequency translation, content adaptation, and QoS negotiation-renegotiation on behalf of users. Figure-2 A UAP stores user, network, and device information, capabilities, and preferences. The overlay network, rather than the user or device, performs handoffs as the user moves from one UAP to another. Common access protocol This protocol becomes viable if wireless networks can support one or two standard access protocols.One possible solution, which will require inter working between different networks, uses wireless asynchronous transfer mode. To implement wireless ATM, every wireless network must allow transmission of ATM cells with additional headers or wireless ATM cells requiring changes in the wireless networks. Figure-3 Challenges: †¢ v 4G definition – A global consensu s on the 4G definition is needed before the standardization starts. – Despite efforts there still are too many diverging approached to 4G. †¢ Seamless connectivity – Inter- and intra-network connectivity is fundamental to the provision of temporally and spatially seamless services. – Vertical and horizontal handovers are critical for 4G.In the former case, the heterogeneity and variety of networks exacerbate the problem. †¢ Latency – Many 4G services are delay sensitive. – Guaranteeing short delays in networks with different access architecture and coverage is far from straightforward . †¢ 4G definition – A global consensus on the 4G definition is needed before the standardization starts. – Despite efforts there still are too many diverging approached to 4G . †¢ Seamless connectivity – Inter- and intra-network connectivity is fundamental to the provision of temporally and spatially seamless services.  œ Vertical and horizontal handovers are critical for 4G.

Open Wireless Architecture (OWA) A single system ar chitecture characterized by a horizontal communication model providing common platform to complement different access technologies in an optimum way for different service requirements and radio environments is called the converged broadband wireless platform or open wireless architecture (OWA). OWA will be the next storm in wireless communications, fueled by many emerging technologies including digital signal processing, software- definable radio, intelligent antennas. The open wireless platform requires: Area and power-efficient broadband signal processing for wideband wireless applications †¢ Highest industry channel density (MOPS pooling) in flexible new BTS signal processing architectures †¢ BTS solutions scalable to higher clock rates and higher network capacity Space-Time Coding and MIMO(Multiple-Input-Multiple-Output) Increasing demand for high performance 4G broadband wireless mobile calls for use of multiple antennas at both base station and subscriber ends. Multi ple antenna technologies enable high capacities suited for Internet and multimedia services and also dramatically increase range and reliability.. [pic] Figure-4 The target frequency band for this system is 2 to 5 GHz due to favorable propagation characteristics and low radio-frequency (RF) equipment cost. AdvantagesSpatial diversity and coding gains for large link budget gains (>10 dB). Disadvantage Multiple antennas at the transmitter and rece- iver provide diversity in a fading environment. 2. Spectrum-efficient High-speed wireless mobile transmission Wide-area wireless broadband systems spectral efficiency can yield a system capacity that allows that experience to be delivered simultaneously to many users in a cell, reducing the cost of service delivery for this mass-market broadband service. These systems are optimized to exploit the full potential of adaptive antenna signal processing, thereby providing robust, high-speed connections for mobile users with a minimum of radio in frastructure.Reduced spectrum requirements, minimizing up-front capital expenses related to spectrum †¢ Reduced infrastructure requirements, minimizing capital and operating costs associated with base station sites, translating into reduced costs per subscriber and per covered population element The acquisition of spectrum is a key component of the cost structure of wireless systems, and two key features of spectrum have great impact on that cost ( the spectral efficiency of the wireless system and the type of spectrum required to implement the system. A fully capable and commercially viable mobile broadband system can operate in as little as 5 MHz of unpaired spectrum with a total of 20 Mbps throughput per cell in that amount of spectrum.Factors contribute to the spectral efficiency of a system 1)Modulation formats, Air interface overhead 2)Multiple access method, Usage model. The quantities just mentioned all contribute to the bits/second/Hertz dimensions of the unit. The app earance of a â€Å"per cell† dimension may seem surprising, but the throughput of a particular cell’s base station in a cellular network is almost always substantially less than that of a single cell in isolation. Future of 4G: â€Å"The future of wireless is not just wireless, it is a part of life. † The future offers faster speeds and larger bandwidth. It is suggested that 4G technologies will allow 3D virtual reality and interactive video / hologram images.The technology could also increase interaction between compatible technologies, so that the smart card in the handset could automatically pay for goods in passing a linked payment kiosk (i-mode can already boast this capability) or will tell your car to warm up in the morning, because your phone has noted you have left the house or have set the alarm. 4G is expected to provide high-resolution images (better quality than TV images) and video-links (all of these will require a band width of about 100MHz). Con clusion: ? From user driven perspective, the user has freedom and flexibility to select the service, at a reasonable QoS and price, anytime, anywhere Reconfigurability: Next-generation wireless network interfaces need to be able to switch seamlessly between different communications standards, in order to provide the most suitable level of service while the user moves across different environments. ? 4G, convergence of networks, technologies, applications and services, will offer a personalized and pervasive network to the users. ? Convergence is heading towards an advent of a really exciting and disruptive concept of 4th generation mobile networks.

Most of the mobile phones are been smart which are capable of doing all sort of operation done in computers, are able perform video conference, etc. For such high performance may not be capable to operate in 3G network until a fully integrated IP network is created. For this features the next generation network was introduced the 4G.

Achievements of India in Space Research Essay Example

Achievements of India in Space Research Essay Example Achievements of India in Space Research Essay Achievements of India in Space Research Essay The Indian space program began establishing itself with the launch of sounding rockets, which was complimented by Indias geographical proximity to the equator. These were launched from the newly-established ThumbaEquatorial Rocket Launching Station (TERLS) , built near Thiruvananthapuram in southern Kerala. Initially, American sounding rockets like the Nike-Apache, and French sounding rockets like the Centaure, were fired and used for studying the upper atmospheric electrojet, which until then had only been studied from ship-based sounding rocket launches in the Pacific Ocean. These were soon followed by British and Russian rockets. However, since day one, the space program had grand ambitions of developing indigenous technology and India soon began developing its own sounding rockets, using solid propellants -these were called the Rohini family of sounding rockets. As the Indian Rohini program continued to launch sounding rockets of greater size and complexity, the space program was expanded and eventuallygiven its own government department, separate from the Department of Atomic Energy. In 1969 the Indian Space Research Organization(ISRO) was created from the Indian National Committee for Space Research (INCOSPAR) program under the DAE, continued under the Space Commission and finally the Department of Space, created in June of 1972. (1970-1980) In the 1960s, Sarabhai had taken part in an early study with NASA regarding the feasibility of using satellites for applications as wide as direct television broadcasting, and this study had found that it was the most economical way of transmitting such broadcasts. Having recognized the benefits that satellites could bring to India from the very start, Sarabhai and the ISRO set about designing and creating an independent launch vehicle, capable of launching into orbit, and providing the valuable experience needed for the construction of larger launch vehicles in future. Recognizing the advanced capability India had in building solid motors with the Rohini series, and that other nations had favoredsolid rockets for similar projects, the ISRO set about building the technology and infrastructure for the Satellite Launch Vehicle (SLV) . Inspired by the American Scout rocket, the vehicle would be a four-stage all-solid vehicle. Meanwhile, India also began developing satellite technology, anticipating the remote sensing and communication needs of the future. Indias first foray into space began with the launch of its satellite Aryabhata in 1975 by a Soviet booster. By 1979, the SLV was ready to be launched from a newly-established second launch site, the Shriharikota Rocket Launching Station (SRLS) . The first launch in 1979 was a failure, attributed to a control failure in the second stage. By 1980 this problem had been worked out. The first indigenous satellite launched by India was called Rohini-1 . (1980-1990)Following the success of the SLV, ISRO was keen to begin construction of a satellite launch vehicle that would be able to put truly useful satellites into polar orbits. Design of the Polar Satellite Launch Vehicle (PSLV) was soon underway. This vehicle would be designed as Indias workhorse launch system, taking advantage of both old technology with large reliable solid-stages, and new liquid engines. At the same time, it was decided by the ISRO management that it would be prudent to develop a smaller rocket, based on the SLV thatwould serve as a testbed for many of the new technologies that would be used on the PSLV. The Augmented Satellite Launch Vehicle (ASLV) would test technologies like strap-on boosters and new guidance systems, so that experience could be gained before the PSLV went into full production. Eventually, the ASLV was flight tested in 1987, but this launch was a failure. After minor corrections, another launch was attempted in 1988, this launch again failed. 1990-2000)It was not until 1992 that the first successful launch of the ASLV took place. At this point the launch vehicle, which could only put very small payloads into orbit, had achieved its objective. In 1993, the time had come for the maiden flight of the PSLV. The first launch was a failure. The first successful launch took place in 1994, and since then, the PSLV has become the workhorse launch vehicle - placing both remote sensing and communications satellites into orbit, creating the largest cluster in the world, and providing unique data to Indian industry and agriculture. Continual performance upgrades have increased the payload capacity of the rocket significantly since then. By this time,with the launch of the PSLV not far away, it had been decided that work should begin on the next class of launch vehicles, intended to place larger satellites into geostationary transfer orbit (GTO), and thus a launcher partly derived from the PSLV design, but featuring large liquid strap-on motors and a cryogenic upper-stage motor, was devised -the Geostationary Satellite Launch Vehicle. 2000)Major achievement which seems to have gone largely unnoticed is ISRO’s successful ground testing of the cryogenic engine on November 15, 2007. This test - conducted for its full flight duration of 720 seconds at the Liquid Propulsion test facility at Mahendragiri, Tamil Nadu, puts India on the world map of cutting edge rocket propulsion technology. Only five other nations - The US, Russia, Japan, China and France - currently have this capability. Cryogenicengines are im portant for launch of satellites, particularly of the INSAT variety which operate from a geostationary orbit, some 36,000 km above earth’s surface. To launch these, ISRO uses a vehicle called GSLV (Geosynchronous Satellite Launch Vehicle). This vehicle has three stages of which the third - and the most critical - stage is a cryogenic stage Sofar, India uses a Russian-made cryogenic engine. But with this recent test, the decks are cleared for using an indigenous engine for the next GSLV (GSLV-D3) launch, expected in 2008. Cryogenics studies behavior of materials at very low temperatures - below minus 150 ° Celsius (minus 238 ° Fahrenheit or 123 ° Kelvin) - as found in the upper atmosphere. The cryogenic engine, which uses a combination of liquid hydrogen and liquid oxygen as fuel, needs to run forover 700 seconds for GSLV launches. Space Capsule Recovery Experiment The Space Capsule Recovery Experiment (SRE-1) is an Indian experimental spacecraft which was launched at 03:53 GMT on January 10, 2007 from Shriharikota by the Indian Space Research Organization (ISRO). The launch was conducted using the PSLV C7 rocket, along with three other satellites. It remained in orbit for 12 days before re-entering the Earths atmosphere and splashing down into the Bay of Bengal at 04:16 GMT on January 22. The SRE 1 was designed to demonstrate the capability to recover an orbiting space capsule, and the technology of an orbiting platform for performing experiments in microgravity conditions. It was also intended to test reusable Thermal Protection System, navigation, guidance and control, hypersonic aero-thermodynamics, management of communication blackout, deceleration and flotation system and recovery operations. Chandrayaan-1 First mission to the Moon launched by Indias national space agency the Indian Space Research Organization (ISRO). The unmanned lunar exploration mission includes a lunar orbiter and an impactor. India launched the spacecraft by a modified version of the PSLV C11 on 22 October 2008 from Satish Dhawan Space Centre, Shriharikota, Nellore District, Andhra Pradesh about 80 km north of Chennai at 06:22 IST (00:52 UTC). The mission is a major boost to Indias space program, as India joins Asian nations China and Japan in exploring the Moon. The vehicle was successfully inserted into lunar orbit on8 November 2008. On November 14, 2008, the Moon Impact Probe separated from the Moon-orbiting Chandrayaan at 20:06 and impacted the lunar South Pole in a controlled manner, making India the fourth country to place its flag on the Moon. The MIP impacted near the crater Shackleton, at the lunar south pole, at 20:31 on 14 November 2008 releasing subsurface debris that could be analyzed for presence of water ice. The estimated cost for the project is Rs. 386 crore (US$ 80 million). The remote sensing lunar satellite had a weight of 1,380 kilograms (3,042 lb) at launch and 675 kilograms (1,488 lb) in lunar orbit and carries high resolution remote sensing equipment for visible, near infrared, and soft and hard X-ray frequencies. Over a two-year period, it is intended to survey the lunar surface to produce a complete map of its chemical characteristics and 3-dimensional topography. The Polar Regions are of special interest, as they might contain ice. The lunar mission carries five ISRO payloads and six payloads from other international space agencies including NASA, ESA, and the Bulgarian Aerospace Agency, which were carried free of cost. Objectives The stated scientific objectives of the mission are: To design, develop, launch and orbit a spacecraft around the Moonusing an Indian-made launch vehicle.

Satellite Launch Vehicles Satellite Launch Vehicle (SLV) -an all-solid four-stage satellite launch vehicle. The SLV can place 40 kg into low earth orbit. Augmented Satellite Launch Vehicle (ASLV) -an all-solid five-stage satellite launch vehicle. The ASLV can place 150 kg into low earth orbit. Present Polar Satellite Launch Vehicle (PSLV) -a four-stage rocket with liquid and solid stages. The PSLV can place 1600 kg into polar sun synchronous orbit. Geosynchronous Satellite Launch Vehicle Mark I/II (GSLV-I/II) -a three-stage rocket with solid, liquid and cryostages. The GSLV can place 2200 kg into geostationary transfer orbit. Future Geosynchronous Satellite Launch Vehicle Mark III (GSLV-III) -a three-stage rocket with solid, liquid and cryostages. The GSLV can place 4000-6000 kg into geostationary transfer orbit. Reusable Launch Vehicle (RLV) -a small remote-piloted scramjet vehicle called AVATAR. The RLV will place small satellites into LEO and can be reused for at least 100 launches reducing the cost of launching satellites Launch facilities ISRO operates 3 launch stations: Thumba (TERLS -Thumba Equatorial Rocket Launching Station/Vikram Sarabhai Space Center, Kerala) Shriharikota (SRLS -Shriharikota Rocket Launching Station/Satish Dhawan Space Center, Andhra Pradesh). Balasore (BRLS -Balasore RocketLaunching Station, Orissa). The Shriharikota range is used for launch of satellites and multi-stage rockets. The launch station has two launch pads including the newest Universal Launch Pad. The two launch pads allow the station to hold up to 6 launches per year. The other two launch facilities are capable of launching sounding rockets, and other small rockets that dont produce spent stages. Comparison with other space agencies It is suggested that in terms of technical expertise and experience, ISRO is close to other major Asian space programs, especially China, and in some respects to Japan. Continued development of reliable and cost-effective launch platforms are expected to see commercial costs of launching payloads on Indian rockets fall, perhaps by as much as fifty percent. Once established, the Indian GSLV-III should be able to place 4000 to 6000 kg payloads into GTO Despite ISROs modest funding, it appears to have achieved reasonable successes . India is counted amongst the six major space powersof the world, and is among the top nations in Asia in terms of success and future potential in space. Indian launch vehicles have the capacity for human spaceflight, however, ISRO has stated that it can achieve all Indias commercial and scientific needs through unmanned spaceflight alone, raising the question of whether a crewed spaceflight will occur.

Free Essays on Communication Between Men And Women

â€Å"Effective Communication between men and women† In today’s modern society, communication has become a very important issue in all aspects of our life but especially in relationships. Many times women and men don’t realize that to have a stable relationship they need to learn a good way to communicate. Deborah Tannen and John Gray both agree that men and women can understand each other better if they know and respect each other’s differences. This situation may look too familiar to many couples that for years have struggled to avoid misunderstanding and improve their relationships. According to Tannen, â€Å"men and women talk differently because they are raised in something like two different cultures: a male culture from which young men learn to speak like men and a female culture in which young women learn to speak like women†. These two different types of talking can lead to misunderstandings and confusion. Gray’s theory is similar to Tannen’s but one of the most remarkable differences is his metaphorical use of the planets Mars and Venus by which he doesn’t literally mean that men and women speak different languages, he means it as a way of thinking about relationships. Although there is no definitive answer as to which type of theory is better, both authors offer their own unique advice to improve communication. One of the most important points in Tannen’s reading is understanding her â€Å"private-speaking or rapport talk† by this she means that women tend to feel more comfortable with people they feel close to and comfortable with. By â€Å"public speaking or report talk† she means that men feel better speaking in groups of large people.

Narrative Analysis of Assessment - Assignment Example Experience in Administering the Pre-Test and Post-Test to the Student(s) during the IPPR Lessons Each of the IPPR lesson presented different experiences to the teacher. There was a common trend in almost all the lessons. The students were not performing well in the pre-test. This is despite the fact that they had internalized and understood the concept properly during the previous lesson. However, the performance of the students improved markedly during the post-test. For example, at the end of lesson 1, topic on place value, every student was expected to place numbers of up to four digits in the correct place mat to the thousand place with 100% accuracy. The students were assigned 2-digit problems without regrouping using base ten blocks on the overhead Place Value Mat to activate their prior knowledge. In this test, only five students managed to solve the problems correctly. As this was the first lesson, the students were not well acquainted with the teacher. They exhibited nervous ness and uneasiness when doing the pre-assessment test. Most of the students had not conceptualized the topic resulting in poor results in the pre-test. At the beginning of the lesson, students also demonstrated difficulty in using the teaching aids. The students were not very confident when using the place mat value, the deck index cards, and the base blocks. In addition, the students were unprepared for the lesson. Most of them had not removed their books when I first stepped into the class. When I was administering the pre-test, some of the students had not fully settled. In the post-test, there was a significant improvement from the pre-test. 15-20 students met the objective. They solved 8 or more problems correctly with 10 students out of them solving all problems correctly. Through guidance and continued reassuring by the teacher and a healthy student-teacher interaction, the students understood the concept properly. The students appeared more relaxed when doing the post-test. The use of teaching aids and teacher’s demonstration in the course of the lesson helped the students understand the concept thus improved performance in the post-test as compared to the pre-test (Schoenfeld, 2002). In lesson plan 2, students were supposed to learn computation of whole numbers. At the end of the academic year, the students were expected to multiply or divide 2-digit numbers with 80% accuracy with a calculator and add different digit numbers with regrouping without using a calculator with 80% accuracy. In pre-test, the students were assigned addition and subtraction to activate their prior knowledge. The students demonstrated significant improvement in the pre-test during IPPR 2 as compared to IPPR 1. The students were at ease. They were well acquainted with their teacher. Since the teacher had clearly stated what he expects from each student from the beginning to the end of the lesson, the students were well prepared for the lesson. They had all their books a nd reading materials ready when the teacher entered the classroom. In addition, the student had prior knowledge today’s lesson. However, the students performed poorly in the pretest as compared to the post-test. The teacher encouraged student participation in the class. The teacher called a group of ten students to the front of the class, one at a time, to demonstrate the concept of addition. As each of the ten students walked to the front of t
