Ode to the West Wind versus Life Will

It Is amazing to see the slmllarltles between their poems â€Å"Ode to the West Wind† and â€Å"Life Will† despite the differences In times & cultures as well as the fact that Elshabby didn't know any other language than Arabic was thus Indirectly influenced by the romantic school through his assoclatlon with Apollo school. Both Shelly, in his â€Å"Ode to the West Wind† and Elshabby, in his â€Å"Life Will† follow the tradition of romantic poets in recognizing nature as a rebellious force capable of making a change in our life. Shelly both admires and fears the changes nature's rebellious forces can wreak.Elshabby, however, is consumed by the hope that people will take their cue from nature and become so fully rebellious against oppression till they eliminate all sorts of oppression. Shelley's â€Å"Ode to the West Wind† expresses the hope that its words will inspire and influence those who read or hear it. Perhaps more than anything else, Shelley wanted his message of reform and revolution spread, and the wind becomes the trope for spreading the word of change through the poet-prophet figure. The poem allegorizes the role of the poet as the voice of change and revolution.It discusses political change, revolution, and role of the poet. â€Å"Life Will† by Elshabby is one of the greatest revolutionary poems written in Arab's world. It still lives till now as it had recently inspired the Arab Spring Revolutions, just as it had inspired revolution against colonization throughout the Arab world in the previous century, when it was written at 1933. The poet uses his verses to evoke people to revolt against and get rid of their oppressor, as If he wants his nation to roar at and eliminate them till there Is nothing left to oppress the people.Sometimes, the poet feels as If his people are not as responsive to his outcry as he may wish, but he doesn't lose hope. He Is consumed by hope believing his nation will revolt at last b reaking the chains with a tremendous will that can't be efeated. Both poems are similar In their classical structure & romantic content. â€Å"Ode to the West Wind† consists of five stanzas written In terza rlma. Each stanza consists of four tercets (ABA, BCB, CDC, DED) and a rhyming couplet (EE). The structure & rhyme confirm to classical tradltlon & resembles Dante's â€Å"Dlvlne Comedy†.The poem follows the romantic tradltlon of glvlng nature and Its elements life. It begins with three stanzas describing the wind's effects upon earth, air, and ocean. The last two stanzas are Shelley direct monologue to the wind, asking for its ower, to lift him like a leaf, a cloud or a wave and make him its companion in its wanderings. He asks the wind to take his thoughts and spread them all over the Winter comes, can Spring be far behind? † â€Å"Life Will† consists of six stanzas with a mono rhyme; for each verse ends with an (R). Also, the verses are divided into t wo halves according to classic Arabic poetry tradition.The declamatory beginning of the poem is another feature of classic Arabic poetry. Then Elshabby introduces the elements of nature and their spirit as the speaker of the poem showing an indirect nfluence by Romanticism. â€Å"Almotaqareb† poetry â€Å"bahr† and the (R) mono rhyme lend a quick tempo to the poem absent from Shelly's Ode. The poem is full of certainty shown in the word â€Å"AN† which means â€Å"must† and stressed by the last verse: 131 As opposed tothe uncertainty at the end of Shelly's â€Å"Ode to the West Wind†: ‘If Winter comes, can Spring be far behind?Though both poems give life to nature ; its elements, each expresses this romantic belief in a different manner. â€Å"Ode to the West Wind† personifies the west wind both as a â€Å"Destroyer† and a â€Å"Preserver†. It is seen as a great power of nature that destroys in order to create, that kills the unhealthy and the decaying to make way for the new and the fresh. In â€Å"Life Will†, Elshabby introduces the wind as a link between inspiration and revolution. It is likened to the revolutionary wind insides him. He stresses that people's will to revolt is the real life that can change destiny and destroy the chains oppressing people.Shelly's Ode shows the effect of the Wild West Wind' on land, sky & sea. The first few lines contain sinister elements, such as ‘leaves dead'. These leaves haunt as ‘ghosts' fleeing from something that panics them. Other allusions to death are ‘chariotest' and ‘corpse within its grave'. He contrasts the west wind to the ‘azure sister of the spring a reference to the east wind – whose ‘living hues and odours' evoke a strong contrast to the colours of death. The sky's ‘clouds' are ‘like earth's decaying leaves'.They also are numerous in number like the dead leaves. Through this reference the landscape is recalled again. The ‘clouds' are ‘Shook from the tangled boughs of Heaven and Ocean'. The ‘clouds' can also be seen s ‘Angels of rain', like messengers bringing change. Here, the west wind is two things at once: first he is ‘dirge/Of the dying year'; singing a funeral song about the year coming to an end and second he is â€Å"a prophet of tumult whose prediction is decisive†; a prophet who does not only bring ‘black rain, and fire, and hail', but who Will burst' it.The ‘locks of the approaching storm' are the messengers of this bursting: the ‘clouds'. Elshabby doesn't describe scenery so much as recount what the elements of life advised him. The land speaks to him. She tells him she likes mbitious revolutionary people and curses dead people who want the status quo kept. The poet calls the land â€Å"mother† invoking an intimate relationship between them. He then declares what each element of nature advi sed; the wind roared among valleys, mountains and trees that achieving ambitions means discarding caution and expending the effort to reach the final goal.He contrasts this with people who won't try to climb up the mountains and thus live forever beneath their dreams. He talks about autumn, drinking wine, sea and seeds stressing revival and the cycle f nature and describing spring and its beauty. The turning-point in Shelly's poem is the third stanza. Whereas Shelley had began by accepting the cycle of nature ; death which brings life back, he now turns to â€Å"wistful reminiscence as an alternative possibility of transcendence†.He gives an image of nature ‘so sweet that one feels alludes to his fear of the revolution that would bring about change even while he is wishing for this change. Whereas the first three stanzas began with ‘O wild West Wind' and ‘Thou†¦ ‘ and were clearly directed to the wind, there is a change in the ourth stanza. The fo cus is no more on the Wind', but on the speaker who says ‘If I ‘ Shelley wishes to identify himself with the wind, although he believes that were a he cannot do that: ‘Oh, lift me up as a wave, a leaf, a cloud'.Because he suddenly remembers his inability as a human to soar, he fall upon the thorns of life' and ‘bleed'. Elshabby also aligns himself with nature. First, he calls earth as ‘his mother'. Then he states that the wind and thunder of revolution live in his heart allowing him to listen to the music of rain as if showing him how nature moves and works all round him to encourage people to do the same; to move and work to revolt against oppression. He then asks darkness about hope, but it doesnt answer. It is the lyre that answers.It says that winter brings death but the seeds hide under ground waiting for spring to come alive. There is another dialogue between destiny and elements of nature. Destiny asks when will hope come and spring comes to answ er her with his revival of life. All through this stanza, darkness, winter and death stands for oppression while spring and seeds stand for hope of coming free. He ends the oem with a repetition of the first stanza stressing the idea that destiny must & will respond to those who has ambition for freedom & change.Shelly ends his poem with a question: ‘If Winter comes, can Spring be far behind?. This is of course a rhetorical question because spring does come after winter, but the â€Å"if† suggests that it might not come if the rebirth is not strong and extensive enough. Thus the question has a deeper meaning and does not only mean the change of seasons, but is a reference to death and rebirth as well. Shelly's Ode is about the role of the poet as the agent of olitical and moral change.In this, it resembles Elshabby's poem which invoked the people to revolt against oppression. Both describe nature and its elements as alive, but where Shelly is both admiring and in owe of nature, Elshabby is more direct in invoking the power of nature and revoking caution and fear. Also, where Shelly wishes to have the power of the wind, even though he believes it is impossible, Elshabby aligns himself completely with nature and encourage others to follow his example as the only way they can attain â€Å"life will† which can achieve their dreams nd hopes.Elshabby's poem also evokes more hope & certainty of achieving this hope, ambition & bravery as well as disregard & rejection of caution & fear while achieving it in contrast to Shelly admiration & fear of change. I might be biased in my view that Elshabby's â€Å"Life Will† is stronger and livelier than Shelly's â€Å"Ode to the West Wind†, but in that I might be pardoned as Elshabby's â€Å"Life Will† has been revived with the current Arab Spring giving us renewed hope for change and freedom and coming more alive in the process than Shelly's ode can ever hope to be.

Howard Gardner Biography

Howard Gardner was born on July 11, 1943 in Scranton, Pennsylvania. His parents were refugees from the period of the Nazis, in Germany. As a child he loved music, he later became a great pianist. As a young man he enrolled at Harvard University. Gardner started to study other careers but ended getting inspired by the works of Jean Piaget to study developmental psychology.He is married to Ellen Winner, a developmental psychologist who teaches at Boston College, and they have four children together He spent some time working with two different types of groups, normal and gifted children and brain-damaged adults, Gardner began developing a theory designed to synthesize his research and observations. In 1983, he wrote Frames of Mind  which outlined his theory of multiple intelligences. Gardner believed that people had multiple different ways of thinking and learning.He has since identified and described eight different kinds of intelligence which are: Visual-spatial intelligence Gardne r also identifies spatial ability as one which lasts longest into old age, Linguistic-verbal intelligence which Gardner takes account of the importance of language in thought, and also in terms of music , Mathematical intelligence, kinesthetic intelligence, Musical intelligence in which Gardner investigates neurological basis for the musical ability, Interpersonal intelligence is related to the ways in which we understand and respond to other people, Intrapersonal intelligence is mostly about our cognitive ability to understand ourselves as human beings and Naturalistic intelligence has to do with an individual's ability to perceive patterns in nature and to classify them. He has also believed that there might have been another possible addition of a ninth type which he refers to as â€Å"existential intelligence. Gardner’s theory has had one of the greatest impact in education In 1986 he started to teach at Harvard Graduate School of Education and began his role at Project Zero, which is a research group that focuses in human cognition with a special focus on the arts and was created by by the philosopher Nelson Goodman with the aim of improving learning in the Arts through research But Over this period Project Zero expanded from its original arts learning base to include research into learning across all types of things. Howard Gardner's theory of multiple intelligences has not been accepted within academic psychology. However, it has met with a strongly positive response from many educators. After all, Gardner has been a great psychologist and his theory has inspired many educators, whether it hasn’t or has been accepted in psychology education.

Due Process Video Movie Review Example | Topics and Well Written Essays - 500 words

Due Process Video - Movie Review Example Thus the parent should be compensated for the financial expenses incurred in admitting Stephen to the private school with effective programs for learners having autism. The weakest witness in the due process hearing is the school district. This is because the district did not adopt an appropriate education standard and process for the learners experiencing the autism condition. The IEP requires the school district to provide appropriate and free education to all students experiencing disabilities. The most effective witnesses are the parents. This is because they adequately understand that appropriate education should be legally provided for free. Hence, they should be compensated for meeting the costs of private education. The school district provided a significant rationale or explanation as to why Stephen’s tuition should not be paid or compensated. The board claims that it is only the disabled learners in the public education process who benefit from the free education. The private school education process for the disabled learners is not considered in the free education budget or the IDEA. Hence, compensation should not be paid because Stephen was transferred to a private school. The parent of the disabled learners in the private schools should pay fully for the education expense. The defense team illustrated significant rationale explaining why the school district should compensate the parents. It is the legal responsibility for the school district to provide appropriate education to learners with autism like Stephen, at no cost to the parents. The district did not provide the appropriate education as illustrated through IDEA. Thus the learners with autism were transferred to a private school with the appropriate education for the learners with autism challenges. It is only fair if the school board compensated the parents for the education expenses

SOCIALIZATION - POLITICAL SCIENCE Essay Example | Topics and Well Written Essays - 1250 words

SOCIALIZATION - POLITICAL SCIENCE - Essay Example The left (democrats) claim that the rights to marry should not be intruded upon. I think people should be allowed to exercise their rights (Martin 93). If homosexuals think that gay marriage is good for them, they should be permitted to do it; marry the ones they love based on their informed decisions. Also, as the left speak about their rights that gay marriages should be allowed, I am reminded of my secondary school pal who was believed to be a gay. When the suspect was discovered by other students she was neglected badly and yet nobody had a proof on the same. The student was chased from school without enough evidence; I wish there could be rights to protect such victims. Second, memories of leadership which I learned in secondary school were handy in my liberalism since I learned that institutions or parties are different from leaders. Having heard the poor representation of political parties on the right and on the left, I decided to be a liberal since I discovered that whether a leader is a republican or a democrat as long as he or she can listen to its people, the party will not matter. Based on real leadership, our county can be a good place to be due to its governance; a government for the people, of the people and by the people. Looking at the mess created by the former president of United States: Bush, in banking, market and oil issues among others, it is a fact that the mess will not be fixed by either a republican or a democrat. People might not like what Obama is doing but allow me to say he is trying. Give a Republican to rule United States but magic will not be done to fix the mess. Being a liberal I advocate for good leaders but not goo d parties; right and left will not help (Martin 100). Third, when I was in college I change my mind due to advanced level of thinking; I realized that foreigners are important people in our society since they provide labor. Many foreigners owning businesses, good cars,

Should the IMF and World Bank cancel all the debts of poor countries Research Paper

Should the IMF and World Bank cancel all the debts of poor countries C.Q. Researcher, September 28, 2001, vol. 11, issue - Research Paper Example A good example is the oil crisis of 1973 whereby oil prices escalated forcing governments of many developing countries to borrow heavily from the IMF, the World Bank and other creditors to procure much needed oil supplies. Much of this borrowed capital was spent on noncapital generating ventures or was lost through corruption. This means that these countries were mostly unable to channel these borrowed funds into their economies to fuel economic growth that would in the near future generate the capital necessary to pay off the debt (Palley, 2003, p. 83). Review Proponents of debt abolition have been advocating heavily for cancellation of all debts of poor countries. The most prominent of these is the Jubilee Debt Coalition, a UK-based coalition of local groups and organizations calling for the cancellation of heavy debts owed by developing countries. The issue of debt cancellation is important because heavy debts which are not payable prevent the eradication or reduction of poverty i n the third world. The World Bank and IMF are party to the Millennium Development Goals one of the main aims of which is to significantly reduce the number of the world’s people living below the poverty line (Pettifor, 2003, p. 71 – 73). ... xperiences of countries such as Nigeria, Afghanistan and Iraq indicate that this general lack of insecurity provides a conducive environment for the growth of terrorist organizations with a global reach. These terrorists pose a serious threat to the national security of all countries, including developed countries. The arguments proposed by both proponents and opponents of debt cancellation have their strengths and weaknesses. Proponents include organizations such as the Jubilee Debt Coalition, experts such as renowned economists in the US, and policy makers in the US and the European Union. They have put forward a number of good arguments. Firstly, they argue that many of the loan deals have terms that are unfair to the borrowing poor countries. According to Palley (2003) the interest rates are usually set very high because many of the developing countries are desperate and they borrow on short notice (p. 86). For this reason, the loans end up being very expensive, an unfortunate si tuation considering that the developing countries are the poorest yet they often receive loans that are more expensive than those received by developed countries. In fact, many countries have already paid the amounts they owed several times over because the debt grows faster than they can pay due to high interest. Therefore, it is only fair that the World Bank and the IMF cancel these debts while it is working on a solution to ensure that in future, terms of loans consider the state of a country’s economy and its rate of economic development. Secondly, proponents argue that debt needs to be cancelled in order to harmonize goals of the United Nations with those of the World Bank and the International Monetary Fund. The UN’s Millennium Development Goals heavily emphasize the reduction of

It for my eco class Essay Example | Topics and Well Written Essays - 500 words

It for my eco class - Essay Example This is correct because the First Amendment prohibition against Congress making laws abridging speech does not exempt corporate speech. A potential danger of distinguishing corporate speech from free speech is that it places a limit on free speech. This is a danger because limiting constitutional rights is the same as questioning the integrity of the document and implying that the rights can be selectively applied (Polsby 23). On the other hand, a con of the Supreme Court’s ruling is that it has in a way made it possible for corporations to buy elections because it has opened elections to undue corporate influence over the election process. Corporations bring people together and give them tremendous power and influence that is more than that of individual voters. Another dimension to the ruling’s risk of opening the election to undue corporate influence is the potential for foreign corporate influence (Wilks 67). This risk is imminent especially because of the fact that foreign entities and persons own many corporations in the United States. Allowing foreign corporate influence on the elections of the United States is like creating a lee way for these foreign entities and individuals to support and endorse regimes which support their agenda even if it is not meant to benefit Americans (Smith 36). My opinion on this matter is that despite the advantages that come with this Court decision, it has serious negative implications that cannot be overlooked. Allowing corporations to fund certain political candidates compromises the efficacy of the outcomes of elections. This is because it will make voters feel that their preferred candidate did not win or lose the election justly. This is because voters reckon that corporations have more access to capital than they have and as such the outcomes of elections will represent the voice of corporations more than

Group Behavior in Organizations Essay Example | Topics and Well Written Essays - 2250 words

Group Behavior in Organizations - Essay Example During its production of goods, the company has a history of using group work for effectiveness and efficiency in production. Productivity is the most important component in any organization; members of the group should learn how to work together. For organization’s initiatives and goals to be achieved, group productivity should be enhanced (Kowert, 2002). Any successful supervisor or manager should be in a position to guide his employees in a way that encourages an increase in performance. Being a hired consultant in Johnson and Johnson, I found that the organization has four main problems which will be analyzed in this paper. Thesis statement: This paper will analyze in essence the problems in Johnson’s and Johnson’s Company, the effects caused by the problems upon the group’s production, as well as recommendations to be adhered to in order to increase the productivity of the groups in the organization as seen below. Role conflicts occur in organizations due to individuals having many conflicting responsibilities in the organization. Research has depicted that most role conflicts come as a result of multiple obligations being given to varied groups (Kowert, 2002). Through the research carried out in Johnson and Johnson Company, it is clear that mid-level supervisors are given a lot of roles which include working with the employees they supervise. This has led to many role conflicts with the supervisor. This is due to the fact that the supervisor is expected to report underperforming employees and to collaboratively work with the group. Moreover, conflict roles are also caused by employees being asked to perform tasks which contradict at the same time. For instance, an employee can be asked by one supervisor to increase quality control on Johnson’s baby powder.

Reviews and reaction on a film - Essay Example ocumentary’s primary focus is Sally Mann; however, the documentary takes the viewer through Mann’s personal life with her children, husband, mother, and friends. In effect, the documentary reveals Mann’s personality to the viewer, which makes the viewer understand her photography work. The documentary provides the viewer with an understanding of the factors behind the personal nature of Mann’s photographs. In this case, her preoccupation and strong relationship with her family are instrumental in Mann’s photography since some of work may appear provocative, which underlines her open-mindedness. As earlier indicated, Mann uses old equipment in the contemporary technological era. In this regard, her large format camera requires exposure times of a number of minutes before use. In effect, this shows her patience and calmness, which provides her with the impulse to capture beautiful photographs. In addition, Mann produces her photos in a fragile and old process that makes her lose some photographs in the process. In this case, this is a depiction of a strong sense of idiosyncrasy, which implies her remarkable willingness to pursue unconventional ideas. In conclusion, the documentary depicts Mann as a remarkable individual intent on pursuing her goals. Although she uses old procedures and equipment, Mann’s work is humbling to photographers and all artists since she exploits the flaws of old procedures to produce unintended patterns that enhance her concept and aesthetic values in

Black Leaders Essay Example for Free

Black Leaders Essay Booker T. Washington and William Edward Burghardt Du Bois were influential black leaders. Their leadership strengthened the minds of the black race. During the decades of Reconstruction following the Civil War, African Americans struggled to be assimilated into the new American society. To do this African Americans required social and economic equality. Two great Negro leaders that emerged for this cause were Booker T. Washington and W. E. B. Du Bois. With these two strong-headed men, another problem arose. They both sharply disagreed upon the strategies needed to gain these equalities. Washington preferred a gradual, submissive, and economically based plan. On the other hand, Du Bois relied upon a more agitating and politically aggressive plan. They worked for the advancement of African-Americans in American society, but their methods of achieving this goal and their leadership style differed greatly from one another. It is hard to fathom that two men, who helped to strive for the great goal of racial fairness, could have been such opposites, but it is true. Booker T. Washington, a former slave and the founder of the Tuskegee Institute in Alabama, believed that African Americans needed to accept segregation and discrimination for the time being and concentrate on elevating themselves through hard work and material prosperity. The eventual acquisition of wealth and culture by African Americans would gradually win for them the respect and acceptance of the white community. This would break down the divisions between the two races and lead to equal citizenship for African Americans in the end. Also he urged blacks to accept discrimination for the time being and concentrate on elevating themselves through hard work and material prosperity. He believed in education in the crafts, industrial and farming skills and the cultivation of the virtues of patience, enterprise and thrift. This, he said, would win the respect of whites and lead to African Americans being fully accepted as citizens and included into all strata of society. Washington wanted blacks in the south to respect and value the need for industrial education both from a vantage of American and African experience. Booker T. Washington was born a slave on April 5, 1856 in Franklin County, Virginia. Once the slaves were emancipated, his family moved to West Virginia. There, his family was poor, and he had to work in a salt furnace and then a coal mine. In school he named himself Booker Washington. Only later did he find out his name was Booker Taliaferro. So he combined both names to form his now famous name, Booker T. Washington. He went to school at the Hampton Institute, which was an industrial school for blacks. Later on, he based his educational theories on his time at Hampton. He founded the Tuskegee Institute, which was a Negro school, which eventually became known for its hardworking, reliable graduates. William Edward Burghardt Du Bois was born into an affluent family on February 23, 1868 in Great Barrington, Massachusetts. Bois took college preparatory classes while in high school. He was also a column writer of a newspaper, the New York Globe. While still young he attended town meetings to listen to people discuss concerns of the town. He spoke about Wendell Phillips at his high school graduation. Du Boiss mother unexpectedly died in 1884. After high school, he attended Fisk University in Nashville, Tennessee. He was the first black person to obtain a Ph. D. from Harvard. He taught at Atlanta University. At Fisk he took part in public speaking and debates. He edited the Fisk Herald, the schools paper. At Fisk he realized that his goal was not for his own happiness, but for the advancement of the black race. He graduated from Fisk in 1886 with an A. B. degree. After Fisk he was accepted into Harvard. In 1895 Du Bois became the first African American to get a Ph. D. from Harvard. Even with a Ph. D. from Harvard he did not feel he was ready to deal with the problems that African Americans faced. He then spent two years at Berlin University. This gave him an extended outlook on the race problem. In the south, African Americans received segregated and unequal education established by white Americans. Du Bois was confident that he could get white Americans to give up discrimination. Du Bois was motivated to lead African Americans out of the disadvantaged position they seemed to be in. He believed the key to their advancement was in education. Near the end of the 1800s African Americans occupied unskilled jobs in southern cities. Their economic situation was not good. Du Bois felt compelled to work to improve this situation. He initially wanted to dedicate his life to education. In 1909 he contributed to the development of the National Association for the Advancement of Colored People (NAACP). According to Gerald Hynes, Du Bois was not pleased with the group, due in part by it being under the leadership of whites. He agreed to work with them and became the editor of The Crisis (1909-1934), a publication from the NAACP. He also led the Niagara Movement. The Niagara Movement was an organization founded by black Americans to racial discrimination. The movement placed most of the blame for Americas racial problems on whites. It opposed the view of Booker T. Washington. He later became a Marxist and a Communist. Washington and Du Bois were alike in few ways. They were both black leaders. They were both teachers and authors. They were also both subject to discrimination from whites. They were both spokesmen for their separate ideologies. Du Bois and Washington were polar opposites of each other in every aspect except for the reasons previously stated. They were so much so that Du Bois published a book named The Souls of Black Folk, which contained many essays criticizing Washingtons views. Du Bois went on to write many other essays and speeches opposing the viewpoints of supposed Uncle Toms. The author believes that Booker T. Washington developed a leadership style based on the model of the old plantation house servant. He used humility, politeness, flattery, and restraint as a wedge with which he hoped to split the wall of racial discrimination. His conciliatory approach won the enthusiastic support of the solid South as well as that of influential Northern politicians and industrialists; their backing gained him a national reputation and provided him with easy access to the press. Members of his own community were filled with pride to see one of their own treated with such respect by wealthy and influential leaders of white America. Du Bois assigned Washington of giving the black race the distinct status of civil inferiority. Washington was for surrendering basic human rights and dignity for economic advancement. Du Bois thought that was detrimental to the black race. Washington thought that a vocational education was far more important to blacks than higher education. Du Bois thought that the really important things in life laid in the realm of the mind. The term The Talented Tenth was the trademark of his educational philosophy. To him, this was, The Talented Tenth of the Negro race must be made leaders of thought and missionaries of culture among their people. No others can do this work and Negro colleges must train men for it. The Negro race, like all other races, is going to be saved by its exceptional men. In the authors opinion, theres any question that Booker T. Washington did accept segregation. Booker T. Washington was an accommodationist. And his program was to accommodate the social and political situation of the South. Du Bois was not in complete disagreement with Booker T. Washington. Du Bois referred to Booker T. Washington as the greatest black leader since Frederick Douglass. And also referred to Washington as the most distinguished man, black or white, to come out of the South since the Civil War. So it wasnt as though Du Bois disagreed with Washingtons program, but Du Bois felt that there was room for more than one solution to the problem. And just as Washington advocated vocational education for the majority of African Americans in the South, Du Bois felt yes, there were African Americans in the South, perhaps the majority who at that point in their historical development were better off with vocational education. But there were others among the race who needed to be the individuals who were at the top, the individuals who did the training, the individuals who were the intelligentsia. And that you needed this group of people. And I think that was the basis of their disagreement. Not that Du Bois felt that Washington was completely wrong, but that Washington needed to have more than just one way of approaching the problem. And then of course the other issue on which they disagreed was Du Bois did not feel that you could accommodate injustice. And he felt that Washington was placing upon his shoulders an extremely heavy responsibility by advocating that African Americans accommodate the social and political system in the South. Washington stated that blacks should work hard and become economically prosperous before they should ask for racial equality from the whites. Du Bois thought that this was absolutely preposterous. Blacks shouldnt have to ask for equality from whites, it is Gods gift to them and every human being deserved it. Du Bois believed that the whites were responsible for keeping the black men down and that the black man should cry out and declare his independence. Washington wanted to please the whites, because he thought that was the only way anything good could happen. Even when he was a child, he made his name Washington, whom was a well-known white historical figure of prominence. Du Bois was more radical, whereas Washington was very moderate. Washington was a realist, Du Bois was a romantic. Du Bois wanted to stir mens hearts, Washington wanted to stir mens minds. Washington was loyal to his country, Du Bois was loyal to his race. Washington was possessed humility, and could relate to the common man, Du Bois was arrogant, egotistical, and imperious. Since he could not believe that the average Southern white man had any desire to help the Negro, Du Bois could see no future in the South for the ambitious young people of his race. Directly contradicting Washingtons counsel, Du Bois urged them to go North for freedom and advancement. He encouraged urban migration at every turn, believing that the country represented oppression and serfdom, while the city represented opportunity. It is very clear to see that their experiences were different and this is very important in understanding how they saw the future of the race. But its also important to keep in mind that for both of them, race uplift was the central key. Despite all of Du Bois attacks on him, Washington still managed to be more popular at the time, and more famous today.

Prices of Petrol and Diesel in Malaysia

Prices of Petrol and Diesel in Malaysia 1.0 Introduction Microeconomics is a branch of economic analysis that are deals with human behavior and the choices of the small units in economics. It is firms in undertakes to understand the decision-making process of firms and households. It is also concerned with the interaction between sellers and individual buyers and all the factors that had influence the choices that are made by buyers and sellers. In particular, microeconomics had focuses on the patterns of supply and demand and also the output in individual markets and the determination of price. There are two different distinct areas in the field of economic will be study that is microeconomics and macroeconomics. Microeconomics studies on how the pricing of element services such as profits, interest, wages and rents are all determined in the market. It is also on how scanty resources are distribute for the production of several products. People who have any wish to start their own business or who want to learn the rationale behind the pricing of the particular services and products. On the other hand, macroeconomics analyzes the accumulate behavior of the whole economy. It studies not just only individual economic units but all the arrangement which are deals with accumulates such as trade cycle, inflation, national income, deflation, public finance and others. Demand and supply including all those important concepts and it is a principle of economic of pricing. Demand and supple concept are using to determining all the prices of goods. Demand is the willingness and ability to buy specific quantities of goods in a given period of time at a particular price. The law of demand states that the higher the price of a good, the lower the quantity demands for that good and vice versa. It also states that there is a reverse relationship between quantity demanded and price. A demand schedule for the graphs had also represents a functional relationship between quantity demanded and price. Supply is clarifies as the willingness and the ability to produce or sell particular services and goods in a given period of time at a particular price. (DevigaVengedasalam, KarunagaramMadhavan and RohanaKamaruddin, 2008) The difference between demand and supply is the word of sell and buy. The law of supply states that the higher price of a good is the quantity supplied for that good and vice versa. The supply schedule for the graphs had also represents a functional relationship between the quantities supplied and price when the other determinants are assumed that all constant. Elasticity is an important concept that can be measured by all the students that are majoring in economics. There are four types of elasticity that is income elasticity (YED), cross price elasticity (XED), price elasticity of supply (PED) and price elasticity of demand (PED). It is a measurement of the proportion of responsiveness of any variable to the change in one of the factors of determinants. 2.0 Demand and Supply On October 2, 2014 petrol and diesel price are increased by 20 cent per litre by Malaysia Government as in line with the federal government’s subsidy rationalization policy. The new retail price of RON95 will be RM2.30 and diesel will be RM2.20 per litre. This change had affected the demand and supply for all the Malaysian consumers. For petrol, the determinants of supply for this case that had happen is the government policies. The supply of goods is also influence by the carry out of various government policies such as subsidies and taxes. If the government charges the sales tax on goods, this will result in the higher cost of production and this will also decrease the supply of goods. Then, the proviso of the subsidies will encourage all the sellers to supply more as the subsidy will reduce the cost. For an example, if the government gives subsidies for goods, the supply of goods will increase. Under these circumstances, the supply of petrol will decrease. â€Å"Although fuel prices have increased for March, prices at farmers’ markets will be still be lower as compared to other markets,† (Ismail, 2015). The government reduces the subsidy rate of petrol. (Themalaymailonline, 2014).From this, it can be seen that the future price of petrol will decrease in demand and supply. For additional, income is the determinant of demand. It can be using to influence the consumers making a decision to buy products or goods or services are the income of consumers. The evident for this determinant is the level of income in country under analysis or appropriate region. The goods that are known as normal good are books, cars, shirts and house. In additional, inferior goods are those salted fish, low-grade potatoes and low-grade rice. The higher income of a consumer getting, the higher quantity of the product they will buy. In fact, when the price of petrol had increase, the demand for petrol is decreasing as the price of related goods is cheaper such as bicycle. This is because consumer having the choice of making a decision to make a desire for things. The demand for petrol in Malaysia is decreasing as the income for every consumers in Malaysia is decreasing or even remain constant. For a better know, the labor market in Malaysia also can be concerned. A worker’ s day can be divided into hours of leisure and hours of work. Besides of that, workers are also be assumed that they have the flexibility to choose their hours for working and leisure. After the year 2013, the minimum wage for Malaysian is not increasing. (MOHR- Minimum Wages, 2013). The minimum wage in Peninsular Malaysia is RM 900 for monthly and RM433 for hourly. Besides, the minimum wage in Sabah, Sarawak and Labuan is RM 800 for monthly and RM3.85 for hourly. (MOHR- Minimum Wages, 2013). As the demand of petrol is decreasing, the number of public transport in Malaysia is increasing. This will happen because all the Malaysian only willing to use on those transport that will not using up the need of petrol. For diesel, government policies is the determinant of supply that is same with the determinant supply for petrol. The supply of goods is also influenced by the implementation of several government policies such as subsidies and taxes. If the government imposes sales tax on goods, this will result in the increase of cost and this will decrease the supply of goods. Then, the proviso of subsidies will encourage all the sellers to supply more as the subsidy will reduce the cost. For example, if the government provides subsidies for goods, the supply of goods will increase. Under these circumstances, the supply of diesel will decrease. Through all of these, it can be seen that the future price of diesel in demand and supply is decrease. In additional, income is the determinant of demand for diesel. The evident is the level of income country under analysis or in an appropriate region. As all the Malaysian knows that diesel is more expensive than the petrol. In this case, the consumers also have more choice to choose or make a decision in individual. Same as the determinant of demand for petrol, the increase of the income of consumer, the quantity of demand also will increase. The demand of diesel in Malaysia is decrease as the price of diesel had already in a higher price than petrol so that the consumer will be lesser and lesser. And this may lead to the firms because in originally diesel already less people use because of the high price. After the year 2013, the minimum wage for Malaysian is not increasing. (MOHR- Minimum Wages, 2013). The minimum wage in Peninsular Malaysia is RM 900 for monthly and RM433 for hourly. Besides, the minimum wage in Sabah, Sarawak and Labuan is RM 800 for monthly and RM3.85 for hourly . (MOHR- Minimum Wages, 2013). This also may increasing the number public transport in Malaysia. 2.1 Graph Demand and Supply of Petrol 2.2 Graph Demand and Supply of Diesel 2.3 Types of Elasticity Price Elasticity of Demand (PED) A measurement of how much the quantity demanded of a good responds to a change in price of that good. It shows the relationship between the price and quantity demand and also had provides an accurate to calculate the effect of a change in price on quantity demand. Then, the price elasticity of demand is calculated as the percentage change in quantity demand divide by the percentage change in price. This equation can use to do the calculation that is about the effect of price changes on quantity demand and on the income that received by the company before and after any price change. After that, the value of price elasticity can classify in five types, such as elastic, inelastic, unit elastic, perfectly inelastic and perfect elastic. The level of response of quantity demand to a change in price can be varying considerably. The quantity demanded changes proportionately more than the price, the value of price elasticity of demand is greater than 1 that is elastic. The percentage that changes in quantity of good is greater that the percent change of that goods price such as petrol. When the quantity demand of PED is less than 1, is call inelastic and the quantity demand is move proportionately less that the price of good. Next, when the value is equal to 1 is called as unit elastic, and the quantity of demand is moving about the same amount as the price of good such as insurance package. When the quantity demand of PED is equal to 0 it is a perfectly inelastic, the price of good and the quantity demand is remain same such as coffin. In addition, when the quantity demand of PED is equal to infinity it is perfectly elastic that means has a small change in the price that had lead to huge change in the quantity demand s uch as housing. Cross Price Elasticity of Demand (XED) Cross price elasticity of demand is show the relationship between two services or goods. Cross price elasticity of demand can defined as a measurement responsiveness of the quantity demand of one good to change in the price of another good. In additional, the cross price elasticity of demand can calculate as the percentage change in quality of good1divided by the percentage change in price of good2. Then, cross price elasticity of demand may be negative or positive value, depend on whether the goods are substitutes or complements. While, if the good A is substitute for good B, when the price of good A increase, thus the coefficient value is positive. For example, if the price of coffee increases, the consumer may purchase more tea and less coffee. In opposite, when the price of another good is decrease, the demand of substitute goods will fall. In contrast, if the good C is a complimentary good for good D, demand for good C decline when the price of good D increases. For example, when the quantity demand of car is increase, the quantity demand of fuel also will increase. If the price of complement falls, the quantity of demand of other good rise. So, the complement goods in cross price elasticity of demand will be negative. In summary, when the degree of elasticity for good XY is negative, the types of goods is complimentary; when the degree of elasticity for good XY is positive, the types of goods is substitute goods; when the degree of elasticity for good XY is equal to zero, , the types of goods is no relat ed goods. Income Elasticity of Demand (YED) Income elasticity of demand can defined as a measure the responsiveness of quantity demand for good to change in the consumer income. The income elasticity of demand can be calculates in the equation of the percentage change in quantity demand divide by the percentage change in income. Income elasticity can used to predict the potential of market. The one of the determinants of consumer demand is income. Income elasticity has shown the changes in income are leading to the change in demand. YED also can use to classify the goods such as luxury goods, inferior goods, necessity goods or normal goods. When a high value of income elasticity for one good, the producer of good can predict to increase in sales or decrease when the elasticity coefficient fall. When the income elasticity coefficient is more than 0, its’ degree of elasticity is elastic and had reveals that it is a luxury good. Luxury goods are the product that are highly desire and associate with wealthy people who bought for some reasons such as to support their status. For example, Gucci, Dior, and LV. When the income elasticity is less than 0, it shows it is an inferior good. Its’ degree of elasticity is negative elastic. The demand for the inferior good is go down as the income is increase such as bus. This is because when the income of people decrease, they just can afford to take a ride but not buying a car. The decline of bus is when the income of people increase. When the income elasticity is greater than 0 and less than 1, it is a normal good and that is the one where demand is directly proportional to the income. Normal goods are the items that income and demand will increase at the same time such as Nike shoes and Polo T-shirts. For example, Polo T-shirts having a normal price so that people are going to make more income to buy it. When the income elasticity is equal to 0, it is a necessity good, this is because the change of income did not affect the good. Necessity goods are the goods or service that are consider to be live in living, such as water, food, and medical care. However, if the price of necessity goods is increasing, people are still buying them because it is necessary for them. Price Elasticity of Supply (PES) Price elasticity of supply is a measurement of the responsiveness in the quantity supplied to a change in price of that good. PES can be calculated in the equation of percentage change in quantity supplied divide by the percentage change in price. There are several factors that can affect the elasticity of supply that is the flexibility of seller to produce, perishability, technology improvement, availability and mobility of factors of production and time period. PES is necessary for all the company to know about how quickly and effectively to it that can respond to change all the market condition, especially to the change of price. The price elasticity of supply can be divided into five types of supply curve. When the price of elasticity is greater than 1 it is elastic and that means the quantity supply is moving proportionately more than the price. When the PES is less than 1it is inelastic which means the quantity supply is moving proportionately less than the price. When the PES is equal to 1 it is unit elastic, which means the quantity supply is moving at the same amount as price. When the PES is equal to 0 it is perfectly inelastic which means that regardless of the price and the quantity supply remain the same. When the PES is equal to infinity it is perfectly elastic and it means that a huge change in the quantity demand that is led by a small change in the price. Graph of Price Elasticity of Demand Graph Price Elasticity of Supply 3.0 Conclusion In the future, the price of the petrol and diesel will decrease. Next is the type of the elasticity can help all the people to classify the goods in the market such as necessity goods, luxury goods, normal goods, inferior goods, substitute goods and complimentary goods. And also this concept is important and applicable. After that, the value of PED and PES can be classify as six elasticity, such as perfectly elastic, inelastic, unit elastic, elastic and perfectly elastic. The concept of demand and supply is important because it is the basis of economic of pricing. For the elasticity concept, it is also very important for the business man so that they can change the market or condition for their business. However, if the future price of petrol and diesel is increasing the government should increase the income of consumer, decrease the tax or provide the subsidiaries on the petrol and diesel. So that the consumer can make a better decision for individual.

IEEE 802.11 family i.e. Wireless Local Area Networks (WLANs) have become popular for allowing low cost data transmissions [1]. The most common and approachable places, such as airports, hotels, shopping places, university campuses and homes have been provided with WLAN Access Points (AP) which provide hotspot connectivity . The future advances in modern radios like Software-Defined Radio (SDR) and cognitive radio technologies will surely facilitate the need of multi-mode, multi-interface and multi-band communication devices. This heterogeneous networking paradigm will certainly enable a user to enjoy better service quality, ease of use and mobility, while keeping in view the application needs and types of available access networks e.g. cellular network, WLAN, wireless personal area network (WPAN) etc. 1.1 Mobile Ad hoc Networks The Mobile Ad hoc Network (MANET) is a network formed by mobile wireless hosts without (necessarily) using a pre-existing infrastructure and the routes between these hosts may potentially contain multiple communication hops [2]. The autonomous nature of participating mobile nodes enables MANETs to have dynamic and frequently changing network topology. The nodes are self-organizing and behave as routers. The ease and speed of deployment and decreased dependence on infrastructure have made ad hoc networks popular within very short span of time. MANET variations include Personal area networking (e.g. cell phone, laptop, ear phone), Military environments (e.g. soldiers, tanks, aircraft), Civilian environments (e.g. cab network, meeting rooms, sports stadiums), and foremost Emergency operations (e.g. search-and-rescue, policing and fire fighting). MANETs rapid deployment, ease of use and subsequent properties make them a hot choice for many important applications. 1.1.1 Resource Sharing One of the intended aspects of MANETs is that it will facilitate the sharing of resources. These include both technical and information resources. Technical resources like bandwidth, Quality of Service (QoS), computational power, storage capacity and information resources include any kind of data from databases. Resource sharing among mobile devices require the devices to agree on communication protocols without the existence of any dedicated servers. 1.1.2 Coordination System Mechanisms that enable the sharing of resources between different mobile devices, i.e. different coordination system is necessary for sharing dissimilar resources. Examples of such mechanisms are Samba, Network File System (NFS) for sharing disk space and the distributed dot net client for sharing processor cycles. 1.1.3 Trust Establishment Before nodes start sharing any resource, they demand a certain amount of trust between them or systems with which they share resources. The level of trust depends on the kind of information or resources that is to be shared. For instance, sharing processor cycles require less trust than the sharing of personal information. Similarly, sharing of profit-making or highly sensitive information can require another level of trust establishment. There are systems currently in operation that can provide a certain amount of trust like the public key infrastructure that makes use of certificates. 1.1.4 Node Discovery Before any node starts communicating with other node, that node must be discovered. When a node enters the network, it has to be capable of communicating to the other nodes about its capabilities e.g. it is a Personal Digital Assistant (PDA) and it has a camera, Global Positioning System (GPS) capabilities and Global System for Mobile Communication (GSM) capabilities etc. When a node is detected, other users can send a query to the new device to find out what it has to offer. Commercial service providers can advertise the resources they have to offer through Internet Protocol (IP) multicasts. There is a myriad of standards that include resource description protocols like Standards Grid Resource Description Language (GRDL), the Web Services Description Language (WSDL) for telling all offer devices a way to describe and publish their specific resources and needs. There are also various different systems currently available that can gather these resource descriptions and structure them for other devices to use. 1.1.5 Resource description For any device to be able to use any resource, a way to identify and describe the resource has to be agreed upon by all available devices. If, for instance, storage capacity is to be shared, it first has to be clear what the capacity of each device is, and, what the storage need is. Although there are techniques to describe certain resources but not one technique that is able to provide this service for all resources. The available techniques combined, however, cover most of what is needed. 1.2 MANET Classifications Mobile Ad hoc Networks are usually categorized as Homogeneous MANETs and Heterogeneous MANETs. 1.2.1 Homogeneous MANETs When MANETs operate in fully Symmetric Environment whereby all nodes posses identical capabilities in terms of battery, processing powers, responsibilities and hardware and software capabilities, thus having no diversity, the network is Homogenous MANET. 1.2.2 Heterogeneous MANETs In certain environments, mobile nodes may have asymmetric capabilities in terms of transmission ranges, Medium Access Control (MAC), battery life, processing powers, speed of movement and software variations etc. Mobility rate may also differ in ad hoc networks due to varying traffic characteristics, transmission ranges, reliability requirements and communication needs. Similarly, addressing and traffic flows like host-based addressing, content-based addressing or capability-based addressing patterns may be defined in certain scenarios; for example, people sitting at an airport lounge, metro taxi cabs, sportsmen playing and military movements etc Homogenous MANETs do not allow for the heterogeneity in the network, which is seriously required in many scenarios, for instance, in a military battlefield network, where soldiers usually carry light portable wireless devices and more powerful equipment like High Frequency (HF) or Very High Frequency (VHF) is installed on vehicles. So, heterogeneous mobile nodes may co-exist in a single ad hoc network making it a Heterogeneous MANET. 1.3 Criterion for Heterogeneous MANETs The integration of different communication networks like cellular networks, WLANs, and MANETs is not straightforward due to various communication scenarios, different interface capabilities and dynamic mobility patterns of mobile nodes. This exhibits many possible application scenarios where devices may unexpectedly interact, create and receive random data streams (video and music etc), or request different network services. The drawback is that each network type typically uses its own protocol stack especially in the case of medium access. In fact, frequency allocation becomes more complicated since different wireless technologies like IEEE 802.11 a and IEEE 802.15.4 may possibly operate in the same frequency band, which makes coexistence mechanisms increasingly important. A heterogeneous MANET paradigm needs to be capable of providing subsequent characteristics. 1.3.1 Transparency The network should be capable of providing seamless end-to-end communication among mobile nodes i.e. the MANET user must not be informed about the route followed or network interfaces traversed by a communication session [3]. 1.3.2 Mobility Integration among dissimilar communication networks must facilitate mobile nodes via some mobility management framework that can manage flow of information through different medium access techniques [4]. 1.3.3 Addressing Most of the IP based networks consider each communication interface as an independent network device running under its own protocol stack [5]. However, this mechanism makes it difficult to remember destinations by IP addresses. So, there must be some mechanism similar to domain name service to recognize mobile nodes with more logical and easy to remember names. 1.3.4 Configuration Various configuration options like network ID, willingness for cooperative communications, desired mobility level and intended services shall be provided to mobile users for their convenience [6]. 1.3.5 End to End security Integration between various networks and data transfer over multiple wireless hops can even expose data to malicious nodes. Security mechanisms must take care of end-to-end data security as well as route security [7]. 1.3.6 Transmission Power and interference of Nodes MANET routing protocols must take care of issues arising due to various communication ranges like communication gray zones [4] and issues arising because of various communication technologies like Bluetooth and WLAN working in same frequency band [1]. 1.3.7 Utilization of Resources In heterogeneous networking paradigm, there may arise situations where some or most of the mobile nodes are installed with different kind of resources. For example, there may be some nodes installed with location monitoring devices like GPS. Now it is the responsibility of routing protocol to benefit from such capabilities in order to facilitate location aided routing and similar services [8]. 1.4 Problem Statement Current research efforts in mobile ad hoc networks are mainly converging towards inclusion of dissimilar communication technologies like IEEE 802.11 [9] and IEEE 802.15.4 [10] to a single mobile ad hoc network. Integrations of different networks like Wide Area Networks WANs (1G, 2G, 2.5G, 3G) and Metropolitan Area Networks MANs (IEEE 802.16) wherein users can access the system through a fixed base station (BS) or AP connected to a wired infrastructure in single hop fashion are also extending towards multihop communication environment using the new and revolutionary paradigm of a mobile ad hoc networks (MANETs), in which nodes constituting MANET serve as routers. Comprehensive research efforts have been done to address the issues related to infrastructure-less multihop communications among nodes installed with dissimilar communication capabilities [3, 11, 12, 13]. However, an investigation needs to be made in order to analyze and address the issues arising from such integrations. Such problems relate to both end users convenience (For example, remembering each destination with its IP address is a cumbersome job specially when every destination may carry multiple IP addresses and any communication interface may optionally be connected or disconnected) as well as networks performance; for example, routing to the best possible interface when there are multiple interfaces installed at destination. Likewise, optimized neighborhood sensing and position based routing can help to improve heterogeneous ad hoc networks performance and scalability. 1.5 Objectives The objective of this thesis is to study the integration of different technologies like WPAN, WLAN and GSM having different capabilities and protocol stacks to mobile ad hoc networks. Performance improvement issues relating to network configuration, human understandable naming mechanism and sophisticated location aided routing mechanisms will also be discussed and evaluated on an actual ad hoc network testbed. 1.6 Thesis Organization Chapter 2 describes the different design and technological challenges arising from integration of multiple communication interfaces. Chapter 3 includes an overview of famous heterogeneous routing protocols architectures, interworking issues encountered, the limitation and solution suggested. Chapter 4 specifically discusses the adopted solution. Chapter 5 presents the details about solution implementation, protocol evaluation testbed, proposed test cases for evaluation of the proposed mechanisms and results obtained, whereas; chapter 6 concludes the research work. Chapter 2 2 LITERATURE REVIEW 2.1 Introduction The literature available on heterogeneous MANETs has suggested different combination of access technologies but no comprehensive solution comprising of maximum access technologies has been suggested yet. Some of the suggested techniques will be discussed in succeeding paragraphs. 2.2 Service Architecture for Heterogeneous IP Networks It was presented by Joe C. Chan and Doan B. [14]. This proposal is presented to resolve two main issues i.e. universal connectivity and MANET location management in heterogeneous networks. The new architecture suggested for Mobile Ad-hoc Systems and Services (AMASS) introduces a new abstraction layer called Mobile P2P overlay in order to cater for the problems such as transparency, dynamic routing, unique addressing, association, and application independence. Mobile users can associate local resources from neighboring devices, build wireless on-demand systems which is independent of location, hardware devices, networking technology and infrastructure availability. Five key design considerations considered were Mobile Peer-to-Peer Overlay, Internet Interworking, Intelligent Overlay Routing, Infrastructure-free Positioning and Application Layer Mobility. Three enhanced mobility models offered in this approach are Personal Mobility (using different IP devices while keeping the same addr ess), Session Mobility (keeping the same session while changing IP devices) and Service Mobility (keeping personal services while moving between networks). The architecture is built on a peer-to-peer communication model to integrate MANETs seamlessly into heterogeneous IP networks. Mobile Peer-to-Peer System(P2P) is a distributed Middleware addresses the demand of direct communication needs by creating spontaneous community. Whenever the Mobile P2P system has global connectivity, it works with its peer system and other applications systems by generic P2P signaling. It consists of Ad-hoc Network layer and Mobile P2P Overlay. The former layer includes wireless hardware and MANET routing software offering homogeneous connectivity among nodes with same wireless interfaces. These nodes act as a router forwarding traffic toward its destination. The later layer includes the following core services: (i) Membership Services offers single sign-on, naming, profile and identity features; (ii) Discovery Services for peer/resource discovery and caching; (iii) Communication Services for Internet interworking, intelligent routing, session control, pres ence and service delivery; (iv) Location Services for infrastructure-free positioning, and user mobility management functions; (v) Adaptation Services for application and network services adaptation. Members of the Mobile P2P system should first sign-in a â€Å"common group† with their exclusive name and password. Some stationary nodes may also join to offer its resources such as Internet connection, printer, video conferencing. Whenever these client devices are within range of each other, they would work together as a team leading to a wireless adhoc service community where local resources could be shared by individual at its will. These members will then be available by intimating their capabilities and location information to the central location server. Information regarding physical location is also essential to offer spatial locality relationships and enable mobile content customization. The results which were achieved through this process can be summarized as first, it maximizes the synergies of MANETs and P2P for building wireless on-demand systems and services. MANETs provide dynamic physical connectivity while P2P offers dynamic associations of entities (users, devices, and services) for direct resources sharing. Second, its Mobile P2P overlay unites mobility, user-centric connectivity, and services for universal communications. This allow dynamic service adaptations pertinent to user location, application requirements, and network environments. Third, it presents a flexible network structure stimulating fixed and wireless networks convergence. The result is an â€Å"Integrated Mobile Internet† which makes our future environment lot better. 2.3 Transparent Heterogeneous Mobile Ad hoc Networks The idea was suggested by Patrick Stuedi and Gustavo Alonso[3]. The paper discussed that performance issues in a personal area network (PAN) or wireless sensor network (WSN) may have less priority than an office network. In contrast, battery life and low cost is vital to PANs and WSN while most probably it is not an issue in an office network. Consider a scenario where in a certain university campus the students carry variety of personal devices like mobile phones, PDA or laptops equipped with different communication technologies tailored to their capabilities. The mobile phones or PDA will be using Bluetooth whereas laptops have 802.11 as well as a Bluetooth interface built in technology. Ubiquitously combining all these devices into one mobile ad hoc network could invite new applications and services such as location based services or VoIP. So there may be an occasion where a personal device of one particular PAN might communicate with a personal device of another PAN in a multi-ho p fashion with the underlying MAC scheme changing per hop. In this scenario two issues needs to be solved i.e. broadcast emulation and handover. Broadcast emulation is not directly supported in Bluetooth (nor on nodes comprising both Bluetooth and 802.11). Handover is an issue because, in the case of heterogeneous MANETs, a handover might include a change in how the medium is accessed. A handover can be caused by node mobility, a change in user preferences (where due to energy constraints the user chooses to use Bluetooth instead of 802.11), or performance reasons. [15] Any device or node supporting multi interface though having different protocol stack will be specific to the interface at lower level. This characteristic will deteriorate the ability of a device to switch from one network to the other. The objective of such network is to provide an end-to-end communication abstraction that hides heterogeneity. The different possible design differs from each other with regard to application transparency, performance and mobility. There is another issue of handover which includes route changes as well as MAC switching. In principle, there are three possible scenarios 2.3.1 Horizontal Handover The horizontal handover between the participating nodes take place when the route changes and underlying MAC technology remains the same. 2.3.2 Vertical Handover The route does not change but the given neighbor is now reached through a new physical interface. 2.3.3 Diagonal Handover The diagonal handover takes when the MAC technology and route between the participating nodes change simultaneously. To address all these issues an IP based heterogeneous mobile ad hoc test bed using Bluetooth and IEEE 802.11 that implements a virtual interface approach as the end-to-end abstraction is presented. 2.4 Stream Control Transmission Protocol Another approach presented by R. Stewart, Q. Xie, and K. Morneault is [16] Stream Control Transmission Protocol, a transport protocol defined by the IETF providing similar services to TCP. It ensures reliable, in-sequence delivery of messages. While TCP is byte-oriented, SCTP deals with framed messages. A major involvement of SCTP is its multi-homing support. One (or both) endpoints of a connection can consist of more than one IP addresses, enabling transparent fail-over between hosts or network cards. Each interface could be separately cond and maintained (AODV-UU [17] e.g., supports multiple interfaces). This solution seems to be quite valuable in terms of performance since SCTP optimizes the transmission over multiple links. In fact, if one particular node can be reached through several interfaces, SCTP switches transmission from one interface to another after a predefined number of missing acknowledgements. Unfortunately, the solution lacks transparency. Applications running traditional unix sockets would have to be changed to use SCTP sockets instead. Another problem arises with the connection oriented nature of Bluetooth. In Bluetooth, interfaces appear and disappear dynamically depending on whether the connection to the specific node is currently up or down. Therefore, this is something that both the ad hoc routing protocol as well as SCTP would have to cope with. 2.5 Global connectivity for IPv6 Mobile Ad Hoc Networks R. Wakikawa, J. T. Malinen, C. E. Perkins, A. Nilsson, and A. J. Tuominen, in 2003 through IETF Internet Draft, 2003 presented Global connectivity for IPv6 Mobile Ad Hoc Networks, suggested one of the solutions for connecting heterogeneous MANETs. Before this work, the issue was solved by the traditional Internet model. But by adopting the approach presented by them the non structured MANETs were made to operate in structured environment, and inevitably limit the extent of flexibility and freedom that an evolving Mobile Internet can offer. Current mobile positioning and network mobility solutions are mainly infrastructure-driven which is contradictory to infrastructure-less MANETs. Without a flexible and user-centric network structure, existing solutions are generally insufficient to handle the dynamic and on-demand requirements of MANETs. 2.6 Conclusion Heterogeneous MANET service architectures and routing protocols have been talked about and it is established that lots of enhancements need to be introduced to the heterogeneous ad hoc networks. First of all, different issues like IP addresses to hostname mapping and seamless communication need to be addressed. Secondly, ad hoc networks must seamlessly utilize all underlying interfaces. Finally, research efforts need to converge towards real-world network deployment as very few MANET service architectures have been evaluated on actual network testbeds. Chapter 3 3 INTEGRATION CHALLENGES 3.1 Introduction The invention of mobile devices like laptops, personal digital assistant (PDA), smart phones and other handheld gadgets having dissimilar communication interfaces smooth the progress of data transmissions without any predetermined infrastructure and centralized administration. [18]. Such data transmissions can only be made on top of infrastructure-less networks composed of fully autonomous mobile nodes. But, these infrastructure-less networks do possess many complexities like dynamic and ever changing topology, heterogeneity in nodes, energy constraints, bandwidth constraints, limited security and scalability. However, there user-friendliness and rapid deployment make them an imperative part of 4th Generation (4G) architecture allowing the mobile users to communicate anytime, anywhere and with the help of any device. 3.2 Technological Challenges The specialized nature of MANETs enforces many challenges for protocol design by incorporating changes in all layers of protocol stack [2]. For instance, all the changes in link characteristics must be dealt with physical layer. MAC Layer should ensure fair channel access and avoidance of packet collision. Calculation of best possible routes among mobile autonomous nodes must be done by the network layer. Transport layer must modify its flow control mechanism to tolerate Packet loss and transmission delays arising because of wireless channel. The continuous making or breaking of connection due to nodes mobility be handled by application layer. These issues at each layer need to be handled effectively in order to smooth the transition from traditional network to advanced MANETs. 3.2.1 The Physical Layer In heterogeneous MANETs there can be a node which may be able to access multiple networks simultaneously. If a node on one hand, is connected to a cellular network, and on the other hand it exists within the coverage area of an 802.11b AP, the network or the node should be able to switch between them. Moreover, in heterogeneous environment, different wireless technologies may operate in the same frequency band and it is significant that they coexist without degrading each others performance. Therefore, techniques to reduce interference between nodes are important. For example, a node communicating with other nodes via multihop path may have lesser interference than a node communicating directly with AP. This is due to the attachment of increased number of nodes to the AP. Another way of reducing interference is Power control techniques applied in code-division multiple access (CDMA)-based cellular networks and MANET [15]. The research issues range from designing considerations to power control techniques include efficient design of nodes that can efficiently switch between different technologies and ensure higher data rates, development of Interference attenuation techniques between various wireless access technologies, modulation techniques and coding schemes that improve the performance of a given technology and frequency planning schemes for increasing the utilization of frequency spectrum 3.2.2 Link Layer The data link layer can be divided into Logical Link Control (LLC) and Medium Access Control (MAC) layers. When a node needs to communicate to another node having cellular interface, it uses a centralized MAC access like Time Division Multiple Access (TDMA) or CDMA with a data rate upto 2.4 Mb/s. On the other hand, when a node communicates in 802.11 environments, it uses distributed random access scheme like Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) upto a data rate of 11 Mb/s. So, this difference of data rate is going to be one of the interworking considerations. Due to dissimilar access technologies at intermediate hops, the performance of ad hoc networks deteriorates. The problems such as hidden and exposed terminals also limit the capacity of MANETs. The need of evolving mechanisms such as power control and power aware MAC protocols is mandatory to improve the performance of ad hoc networks. In a heterogeneous network, the cross-layer design may play a significant role in providing useful information to upper layers. Another important issue to be considered at the link/MAC level is Security. Although, end-to-end security is the responsibility in the application layer, some wireless access technologies provide a certain level of security at the lower layers. Although the link and MAC layers in a multi-interface node can operate autonomously, but their operations have to be optimized to provide definite service to the upper layers. Some of the open issues include design of efficient link and MAC layer protocols to support QoS in Heterogonous MANET, channel administration schemes that consider different categories of traffic, and allow call blocking and handoff failure probabilities and security at Link / MAC layer. 3.2.3 Network Layer The network layer needs to integrate all underlying communication interfaces; therefore, it is the most challenging task. The presence of nodes with multiple communication interfaces allow to have different physical and MAC layer technologies which need to be taken into account while dealing with an integrated routing process. But, the problem of MANETs such as frequent route changes due to mobility, higher communication overhead to learn and uphold valid routes, higher end-to-end delay and limited end-to-end capacity due to problems at the lower layers are main contributing factors in designing of routing process [19]. In order to reduce network control traffic, improve throughput and increase the range, the idea of integrating MANETs with infrastructure networks is evolved. Hence, mechanism to find gateways and correctly con IP addresses is required by such nodes in a MANET. The network layer has to find the best route between any source and destination pair. To define the best route, including number of hops, delay, throughput, signal strength, and so on several metrics can be used. Moreover, the network layer has to handle horizontal handoffs between the same technology and vertical handoffs between different technologies in a seamless manner. Several routing protocols have been presented for heterogeneous MANETs but the design of integrated and intelligent routing protocols is largely open for research with issues like development of routing capability in a heterogeneous environment that supports all communication possibilities between nodes forming MANET, scalability in multihop routing withou t significantly escalating the overhead and study of the impact of additional routing constraints (like co-channel interference, load balance, bandwidth), and requirements (services, speed, packet delay) needed by nodes and networks. 3.2.4 Transport Layer In connection oriented transport session, as in case of Transmission Control Protocol (TCP), packet loss is assumed to occur due to congestion in the network. This assumptions leads to the performance degradation of TCP and factors such as channel errors, jitter and handoffs are overlooked. Moreover, in heterogeneous environments, the transport protocol has to handle the high delays involved in vertical hands off (while switching from one interface to another), server migration, and bandwidth aggregation [16]. Sometimes, a node changes its IP address when it needs

Genetically Engineered Crops Essay -- GMOs Genetically Modified Foods

Genetically Engineered Crops Chemical and seed companies have been working the last several years to alter the genetic make-up of certain crops to combat heavy pressure from insects and weeds. Through genetic manipulation plant breeders have been able to make certain crops resistant to different types of chemicals and insects. Breeders can alter the crops by adding to a specific plant one or more genes from other related crops with a known resistance to an insect or herbicide The use of genetically engineered crops has become a hotly debated topic over the last couple of years. Environmentalists are concerned with how these new crops will affect the environment. Farmers want to know how these crops will help them to increase production and increase profits. Consumers are interested in the possible health risks stemming from these genetically altered crops. There are three main reasons why I support the use of genetically engineered crops. I think genetically altered crops can have fewer negative impacts on the e nvironment, increase farmers' profits through increased yields, and pose no major health risks to consumers. The two types of crops I will focus most of my attention on are corn reistant to the European corn borer and "Roundup" herbicide resistant soybeans. Monsanto, along with other companies, has developed corn varieties to resist European corn borer infestations. The gene inserted in these crops is called Bacillus thuringiensis (Bt). Bt is a natural bacterium in the soil that produces a protein to disrupt the digestive systems of targeted pests (Monsanto Crossroads). This same gene is also used in varieties of cotton to protect against the tobacco budworm, cotton bollworm, and pink bollworm, and in potato varieties... ...'s Next For Designer Seeds?" Top Producer.

To what extent was Hitlers success in coming to power due to the depression? :: World War II History

To what extent was Hitler's success in coming to power due to the depression? Hitler became chancellor in January 1933. By March he had full dictatorial power. There is no doubt that the impact of the depression on the German people gave way to the rise of Hitler. It was the single most important factor of Hitler's coming to power, however it wasn't the only factor. Hitler had remarkable speaking abilities, which helped him woo the public. His use of force with the SA and the inability of the Left wing political groups to combine, also contributed in his rise. Hitler also used the weakness of the constitution the signing of the Versailles treaty to bring down the Weimar Republic. With all these advantages on his side, and with the depression hitting Germany hard in 1929, it was just a matter of time before Hitler would "claim his throne". The Depression was the single most important factor in Hitler's rise to power. In 1929 a shockwave began in New York the affected the entire world. Germany was affected the most. Many historians, including Mckibbin and Taylor, believed that the depression was the turning point for Hitler and the nazi party. Germany's economy after World War I had been built on foreign loans, especially loans from the United States, and on world trade, which was also based on a system of loans. Thus when the depression hit, the German economy collapsed. By 1932, 6 million Germans were unemployed. The German people and lost all hope in the Weimar republic, and started looking for a radical change, brought forth party radical parties...the communists and the nazis. As a result of 1929, Hitler became remarkably popular. He made promises to the military and to industrialists saying that he would return Germany back to greatness once again. Hitler exploited the trust of the German public to its fullest dur ing these times of hardship so he could gain the support he needed to gain full control of the German state. The weakness of the Constitution of the Weimar Republic significantly helped Hitler establish and develop the Nazi party. Whilst the Weimar constitution was said to be one of the most democratic constitutions of all time, there were still major flaws in it. In the eyes of Howland and Barr, the section on proportional representation and article 48 considerably helped Hitler on his quest for absolute power.

John Locke :: Empiricists, Empiricism

John Locke was the son of a country attorney and was born on August 29, 1632 . He grew up in and during the civil war, and later in 1652, entered the Christ Church, Oxford, where he remained as a student and teacher for many years. Locke taught and lectured in subjects such as Greek, rhetoric, and Moral philosophy. Lockedisagreed with many of the topics that were taught at the university. Locke, after reading books by Descartes, acquired a strong interest in contemporary philosophical and scientific questions and theories.   Ã‚  Ã‚  Ã‚  Ã‚  In 1666, Locke accidentally met with Lord Anthony Ashley Cooper, 1st of Shaftesbury, and from then on, this lifelong relationship and association helped to change the course of Locke’s career. Cooper made Locke his personal secretary and confidential advisor, and also let him hold a number of governmental posts while his patron was in office. In 1675, Locke became very ill and was forced to leave his employment and reside for four years in France, where he began his writing. After four years, Locke then returned again to England into Shaftesbury where he once again joined Cooper’s service. Four years later, Cooper was forced to flee to Holland, where Locke, shortly after, followed him. They remained there until the Glorious Revolution of 1688.   Ã‚  Ã‚  Ã‚  Ã‚  On his return to England, Locke issued many or works, the chief of these being the Two Treaties of Government, and the Essay Concerning Human Understanding. These writings were immediately successful and they both exerted a vast influence. Between the both of these works, they made the dominant view of English thought through the greater part of the eighteenth century. Also on his return, the new king, William III, appointed Locke to the Board of Trade in 1696, a position from which he resigned because of ill health in 1700.   Ã‚  Ã‚  Ã‚  Ã‚  Locke spent peaceful old age in the country household at Oates, of his friends Sir Francis and Lady Masham. He spent the last couple of years revising the Essay, replying to his critics, and writing a number of other works on economic,philosophical, and religious topics. Locke died in Oates on October 28, 1704.   Ã‚  Ã‚  Ã‚  Ã‚  Locke’s Two Treatises of Government (1690) was a well-known and respected document. In the paper, he attacked the theory of diving right of kings and the nature of the state as conceived by the English philosopher and political theorist Thomas Hobbes.

“the Yellow Wallpaper” by Charlotte Perkins Gilman

Self expression is one of humanity’s greatest gifts. It is very important that humans express themselves in many different ways, whether it is writing in a journal, painting, singing, or just speaking with someone. Holding in one’s feelings can be unhealthy and it can lead to depression, anxiety, or insanity. In â€Å"The Yellow Wallpaper† by Charlotte Perkins Gilman, the narrator, an upper-class woman rebels against her husband’s â€Å"cure† for her depression, which forbade her to exercise her imagination. She keeps a secret journal in which she records her thoughts and fascination about the yellow wallpaper. As a result of the mental restrictions placed upon her, she loses control over reality. Writing in a journal can be used as a tool to express oneself. A journal can become a safe space to help release anxious thoughts and negative feelings. In â€Å"The Yellow Wallpaper, the narrator writes in her journal, â€Å"I cry at nothing, and cry most of the time. Of course I don’t when John is here, or anybody else, but when I am alone. And I am alone a good deal just now (Gilman 428). One may suggest that the narrator is a very lonely person who hides her true feelings from her husband and everyone else. Her husband shows no interest of her thoughts or concerns for the conditions she is living under. So she continues to hide her depression and uses a journal as her emotional outlet, but her imagination gets the best of her. Not expressing oneself can consequently lead to depression, anxiety, or insanity. For this reason it is important to exercise one’s imagination. In â€Å"The Yellow Wallpaper†, the narrator is forbidden to do anything active and to not exercise her mind in any way. She directs her attention towards the yellow wallpaper and becomes obsessive over it. â€Å"All night in any kind of light, in twilight, candlelight, lamplight, and worst of all by moonlight it becomes bars! The outside pattern I mean, and the women behind it is as plain as can be† (431). The narrator feels enclosed in her room and thinks the patterns in the wallpaper are bars of a cage. She stares at the wallpaper for long periods of time and discovers a woman behind the pattern. One may suggest that she is the women behind the patterns trying to break free. In her last journal entry, she stated, â€Å"I pulled and she shook, I shook and she pulled, and before morning we had peeled yards of that paper† (433). Peeling off â€Å"that paper† on could suggest that she is unraveling the pattern of her domesticated life. Furthermore, in order for the narrator to understand herself, she loses her sanity.
