Frederick Douglass :: essays research papers

Frederick Douglass asserts that he, as an adolescent "understood the pathway from slavery to freedom" upon his comprehension of English reading. To contemporary audiences, this may be a hard concept to grasp, an individual reared from birth as a slave understanding the significance of literacy and equating such with freedom. His cognition of this enormous concept can be explained as such: by breaking the literacy barrier, Douglass raised his status (symbolically) from a subhuman, slave status, to human, a White equal. Because all humans are entitled to certain rights, his symbolic progression from slave to human affords those rights, in particular the right to freedom. Slaves were forbidden to read and slave owners were forbidden to teach slaves to read and write. The existence of such a restriction on educating slaves is proof that the slaveholders felt a need to suppress the capabilities of slaves. As a slave, Douglass was given the opportunity to learn and elevate his status only to have all that, including the invitation to join "high" society snatched away. Such a tease and broken promise of a better day proved to be more than Douglass could bear. He devoted each of his idle moments to mastering the language arts. In addition, as if mastering it were not enough, Douglass meticulously educated other slaves in the English language of reading and writing. Douglass' action was indicative of the significance found in literacy. If he had not put literacy at such high esteem, he would not have taken the time to continue his education and persuade others to pursue theirs. Douglass knew first hand that education was a effective tool of empowe rment especially to slaves—those who had spent their lives without any power. This separation of man from education was a control issue and reclaiming control meant education one's self and his or her peers. Through educating his peers, Douglass demonstrated his knowledge of the underlying power in literacy. Douglass practiced not only reading but also writing his English language.

The Politics of Poverty Exposed in There are No Children Here :: There are No Children Here Essays

The Politics of Poverty Exposed in There are No Children Here At a young age Lajoe, her parents and other siblings were the first family to move into the newly built Henry Horner Homes, a public housing high-rise project, on Chicago’s south side. Lajoe recalls how clean and spacious their apartment was then. As the years passed the city became less and less able to allocate funds to keep up with the repairs the buildings needed and the city seemed not to care. The projects became ran down, dank and to condense to support a large family. Lajoe became pregnant at the young age of fourteen and was unable finish her high school education. Eventually, she married Paul Rivers, the father of her child and had they had six more children. Lajoe’s husband Paul was estranged from them more often than not and rarely offered any support for their children. This story is centered on the lives of the two middle children, Lafayette and Pharaoh, in the family. The older of the two boys, Lafayette, takes on the role of co-parent and support system for his mother by worrying about his younger siblings’ well being, who their friends are and to if they ducking bullets properly in the hallway. He has four younger siblings a brother a few years young than he is and a set of triples. He especially kept a watchful eye on his brother Pharaoh who was weaker and easily intimidated. At one point in the story Lajoe realized that because of her husband absence and lack close adult relationships she had placed an enormous amount of responsibility on Lafayette’s shoulders. Lajoe said, â€Å"The things I should be telling Paul about I was talking to Lafie, I put him in a bad place. But I didn’t have anyone to talk to. Lafie, became a twelve year old man that day.†(101) Lafayette had lost his childhood somewhere in the projects. He lived in constant fear for his life and the lives of those he cared about. He tried to stay out of trouble and to avoid dealing with the gangs. But when you come from the projects it was hard to stay out of trouble. There were many occasions when the police wrongly accused Lafayette and his older brother, Terrence. As Lafayette got older found it harder to avoid the older boys and not get caught up in the fast crowd.

Booker T. Washington (19th century) and Martin Luther King Jr. (20th century) Essay

I. INTRODUCTION For decades, Booker T. Washington (1856-1915) was the major African-American spokesman in the eyes of white America. Born a slave in Virginia, Washington was educated at Hampton Institute, Norfolk, Virginia. He began to work at the Tuskegee Institute in 1881 and built it into a center of learning and industrial and agricultural training. A handsome man and a forceful speaker, Washington was skilled at politics. Powerful and influential in both the black and white communities, Washington was a confidential advisor to presidents. For years, presidential political appointments of African-Americans were cleared through him. He was funded by Andrew Carnegie and John D. Rockefeller, dined at the White House with Theodore Roosevelt and family, and was the guest of the Queen of England at Windsor Castle. Although Washington was an accommodator, he spoke out against lynchings and worked to make â€Å"separate† facilities more â€Å"equal.† Although he advised African-Americans t o abide by segregation codes, he often traveled in private railroad cars and stayed in good hotels. Any number of historic moments in the civil rights struggle have been used to identify Martin Luther King, Jr. — prime mover of the Montgomery bus boycott, keynote speaker at the March on Washington, youngest Nobel Peace Prize laureate. But in retrospect, single events are less important than the fact that King, and his policy of nonviolent protest, was the dominant force in the civil rights movement during its decade of greatest achievement, from 1957 to 1968. II.BOOKER T. WASHINGTON A. HISTORY Booker T. Washington was born a slave in Hale’s Ford, Virginia, reportedly on April 5, 1856. After emancipation, his family was so poverty stricken that he worked in salt furnaces and coal mines beginning at age nine. Always an  intelligent and curious child, he yearned for an education and was frustrated when he could not receive good schooling locally. When he was 16 his parents allowed him to quit work to go to school. They had no money to help him, so he walked 200 miles to attend the Hampton Institute in Virginia and paid his tuition and board there by working as the janitor. Dedicating himself to the idea that education would raise his people to equality in this country, Washington became a teacher. He first taught in his home town, then at the Hampton Institute, and then in 1881, he founded the Tuskegee Normal and Industrial Institute in Tuskegee, Alabama. As head of the Institute, he traveled the country unceasingly to raise funds from blacks and whites both; soon he became a well-known speaker. In 1895, Washington was asked to speak at the opening of the Cotton States Exposition, an unprecedented honor for an African American. His Atlanta Compromise speech explained his major thesis, that blacks could secure their constitutional rights through their own economic and moral advancement rather than through legal and political changes. Although his conciliatory stand angered some blacks who feared it would encourage the foes of equal rights, whites approved of his views. Thus his major achievement was to win over diverse elements among southern whites, without whose support the programs he envisioned and brought into being would have been impossible. In addition to Tuskegee Institute, which still educates many today, Washington instituted a variety of programs for rural extension work, and helped to establish the National Negro Business League. Shortly after the election of President William McKinley in 1896, a movement was set in motion that Washington be named to a cabinet post, but he withdrew his name from consideration, preferring to work outside the political arena. He died on November 14, 1915. From 1872 to 1875, he attended the Hampton Institute, an industrial school for blacks in Hampton, Virginia. He became a teacher at the institute in 1879. Washington based many of his educational theories on his training at Hampton. In 1881, Washington founded and became principal of Tuskegee Normal and Industrial Institute. He started this school in an old abandoned church and a shanty. The school’s name was later changed to Tuskegee Institute (now Tuskegee University). The school taught specific trades, such as carpentry, farming, and mechanics, and trained teachers. As it expanded, Washington  spent much of his time raising funds. Under Washington’s leadership, the institute became famous as a model of industrial education. The Tuskegee Institute National Historic Site, established in 1974, includes Washington’s home, student-made college buildings, and the George Washington Carver Museum. Though Washington offered little that was innovative in industrial edu cation, which both northern philanthropic foundations and southern leaders were already promoting, he became its chief black exemplar and spokesman. In his advocacy of Tuskegee Institute and its educational method, Washington revealed the political adroitness and accommodationist philosophy that were to characterize his career in the wider arena of race leadership. He convinced southern white employers and governors that Tuskegee offered an education that would keep blacks â€Å"down on the farm† and in the trades. To prospective northern donors and particularly the new self- made millionaires such as Rockefeller and Carnegie he promised the inculcation of the Protestant work ethic. To blacks living within the limited horizons of the post- Reconstruction South, Washington held out industrial education as the means of escape from the web of sharecropping and debt and the achievement of attainable, petit-bourgeois goals of self-employment, landownership, and small business. Washington cultivated local white approval and secured a small state appropriation, but it was northern donations that made Tuskegee Institute by 1900 th e best-supported black educational institution in the country. Washington was married three times. His first wife, Fannie N. Smith, his sweetheart from Malden, gave birth to a child in 1883, the year after their marriage, but died prematurely the next year. In 1885 Washington married Olivia Davidson; they had two children. This too was a short marriage, for she had suffered from physical maladies for years and died in 1889. Four years later he married Margaret J. Murray, a Fisk graduate who had replaced Davidson as lady principal. She remained Washington’s wife for the rest of his life, helping to raise his three children and continuing to play a major role at Tuskegee. As Tuskegee Institute grew it branched out into other endeavors. The annual Tuskegee Negro Conferences, inaugurated in 1892, sought solutions for impoverished black farmers through crop diversity and education. The National Negro Business League, founded in 1900, gave encouragement to black enterprises and publicized their successes. Margaret Washington hosted women’s conferences on campus. Washington established National Negro Health Week and called attention to minority health issues in addresses nationwide. By the mid-1880s Washington was becoming a fixture on the nation’s lecture circuit. This exposure both drew attention and dollars to Tuskegee and allowed the black educator to articulate his philosophy of racial advancement. In a notable 1884 address to the National Education Association in Madison, Wisconsin, Washington touted education for Negroes–â€Å"brains, property, and character†Ã¢â‚¬â€œas the key to black advancement and acceptance by white southerners. â€Å"Separate but equal† railroad and other public facilities were acceptable to blacks, he argued, as long as they really were equal. This speech foreshadowed the accommodationist racial compromises he would preach for the rest of his life. During the 1880s and 1890s Washington went out of his way to soft-pedal racial insults and attacks on blacks (including himself) by whites. He courted southern white politicians who were racial moderates, arguing that black Americans had to exhibit good citizenship, hard work, and elevated character in order to win the respect of the â€Å"better sort† of whites. Full political and social equality would result in all due time, he maintained. B. GOALS Washington believed that blacks could benefit more from a practical, vocational education rather than a college education. Most blacks lived in poverty in the rural South, and Washington felt they should learn skills, work hard, and acquire property. He believed that the development of work skills would lead to economic prosperity. Washington predicted that blacks would be granted civil and political rights after gaining a strong economic foundation. He explained his theories in Up from Slavery and in other publications. During Booker’s lifetime, many African Americans were former slaves who did not have an education. Booker’s goal was to provide African Americans with opportunities to learn vocational skills and obtain an  education. He thought former slaves would gain acceptance through education and financial independence. C. METHODS In the late 1800’s, more and more blacks became victims of lynchings and Jim Crow laws that segregated blacks. To reduce racial conflicts, Washington advised blacks to stop demanding equal rights and to simply get along with whites. He urged whites to give blacks better jobs. In a speech given in Atlanta, Georgia, in 1895, Washington declared: â€Å"In all things that are purely social we can be as separate as the fingers, yet one as the hand in all things essential to mutual progress.† This speech was often called the Atlanta Compromise because Washington accepted inequality and segregation for blacks in exchange for economic advancement. The speech was widely quoted in newspapers and helped make him a prominent national figure and black spokesman. Washington became a shrewd political leader and advised not only Presidents, but also members of Congress and governors, on political appointments for blacks and sympathetic whites. He urged wealthy people to contribute to v arious black organizations. He also owned or financially supported many black newspapers. In 1900, Washington founded the National Negro Business League to help black business firms. Throughout his life, Washington tried to please whites in both the North and the South through his public actions and his speeches. He never publicly supported black political causes that were unpopular with Southern whites. However, Washington secretly financed lawsuits opposing segregation and upholding the right of blacks to vote and to serve on juries. Washington offered black acquiescence in disfranchisement and social segregation if whites would encourage black progress in economic and educational opportunity. Washington’s position so pleased whites, North and South, that they made him the new black spokesman. He became powerful, having the deciding voice in Federal appointments of African Americans and in philanthropic grants to black institutions. Through subsidies or secret partnerships, he controlled black newspapers, stifling critics. Overawed by his power and hoping his tactics would work, many blacks went along. However, increasingly during his last years, such black intellectuals as W.E.B. Du Bois, John Hope, and  William Monroe Trotter denounced his surrender of civil rights and his stressing of training in crafts, some obsolete, to the neglect of liberal education. Opposition centered in the Niagara Movement, founded in 1905, and the National Association for the Advancement of Colored People, which succeeded it in 1910. Washington’s power involved not only close relationships with influential white political leaders and industrialists but also a secret network of contacts with journalists and various organizations. He schemed with white and black Alabamians to try to keep other black schools from locating near Tuskegee. He engineered political appointments for supporters in the black community as a way of solidifying his own power base. He planted spies in organizations unfriendly to him to report on their activities and at one time even used a detective agency briefly. Despite public denials, Washington owned partial interests in some minority newspapers. This allowed him to plant stories and to influence their news coverage and editorial stands in ways beneficial to himself. Beginning in the mid-1880s, and lasting for some twenty years, he maintained a clandestine relationship with T. Thomas Fortune, editor of the New York Age, the leading black newspaper of its day. He helped support the paper financially, was one of its stockholders, and quietly endorsed many of Fortune’s militant stands for voting and other civil rights and against lynching. He also supported the Afro-American League, a civil rights organization founded by Fortune in 1887. Washington secretly provided financial and legal support for court challenges to all-white juries in Alabama, segregated transportation facilities, and disfranchisement of black voters. As black suffrage decreased nonetheless around the turn of the century, Washington struggled to keep a modicum of black influence and patronage in the Republican party in the South. From 1908 to 1911 he played a major, though covert, role in the successful effort to get the U.S. Supreme Court to overturn a harsh Alabama peonage law under which Alonzo Bailey, a black Alabama farmer, had been convicted. 1. DISSENT: Lawful Rights Booker T. Washington’s methods included speeches, arguments, and agreements with both races; blacks and whites, without having to associate violence to achieve these goals. D. ACCOMPLISHMENTS â€Å"h As Washington’s influence with whites and blacks grew he reaped several honors. In 1901 he wrote a bestseller called Up From Slavery – his autobiography. He also became an advisor to the President of the United States – Theodore Roosevelt. He became the first black ever to dine at the White House with the President. This created a huge scandal. Many white people thought that it was wrong for whites and blacks to mix socially, and for their President to do it horrified them. Roosevelt defended his actions at the time, and he continued to ask for Washington’s advice, but he never invited him back. Eventually Washington’s leadership of blacks began to decline. It became apparent that the white people that had gained control of Southern institutions after Reconstruction did not ever want the civil and political status of blacks to improve – regardless of how hard they worked or how much character they had. They passed laws to keep them from voting and to keep them from mixing with whites in schools, stores and restaurants. Many blacks came to believe that a more forceful, demanding approach was needed. By the last years of his life, Washington had moved away from many of his accommodationist policies. Speaking out with a new frankness, Washington attacked racism. In 1915 he joined ranks with former critics to protest the stereotypical portrayal of blacks in a new movie, â€Å"Birth of a Nation.† Some months later he died at age 59. A man who overcame near-impossible odds himself, Booker T. Washington is best remembered for helping black Americans rise up from the economic slavery that held them down long after they were legally free citizens. Was chosen in 1861 to head the Tuskegee Normal and Industrial Institute â€Å"h Caused Tuskegee Institute to grow into one of the world’s leading centers of education for African-Americans â€Å"h Founded the National Negro Business League in 1900 â€Å"h Advised Presidents Theodore Roosevelt and William Howard Taft on racial matters â€Å"h Wrote an autobiography, Up From Slavery in 1901 â€Å"h Stressed the importance of education and employment for African-Americans â€Å"h Became a chief spokesperson for his race â€Å"h Advocated cooperation between the races â€Å"h His views caused strife with other African-American leaders, especially W.E.B. Dubois, although in his later years he began to agree with them on the best methods to achieving equality Close analysis of Washington’s autobiographies and speeches reveals a vagueness and subtlety to his message lost on most people of his time, whites and blacks alike. He never said that American minorities would forever forgo the right to vote, to gain a full education, or to enjoy the fruits of an integrated society. But he strategically chose not to force the issue in the face of the overwhelming white hostility that was the reality of American race relations in the late nineteenth and early twentieth centuries. In this sense, he did what he had to do to assure the survival of himself and the people for whom he spoke. III.MARTIN LUTHER KING, JR. A. HISTORY King was born on Jan. 15, 1929, in Atlanta, Georgia. He was the second oldest child of Alberta Williams King and Martin Luther King. He had an older sister, Christine, and a younger brother, A. D. The young Martin was usually called M. L. His father was pastor of the Ebenezer Baptist Church in Atlanta. One of Martin’s grandfathers, A. D. Williams, also had been pastor there. In high school, Martin did so well that he skipped both the 9th and 12th grades. At the age of 15, he entered Morehouse College in Atlanta. King became an admirer of Benjamin E. Mays, Morehouse’s president and a well-known scholar of black religion. Under Mays’s influence, King decided to become a minister. King was ordained just before he graduated from Morehouse in 1948. He entered Crozer Theological Seminary in Chester, Pennsylvania, to earn a divinity degree. King then went to graduate school at Boston University, where he got a Ph.D. degree in theology in 1955. In Boston, he met Coretta Scott of Marion, Alabama, a music student. They were married in 1953. The Kings had four children–Yolanda, Dexter, Martin, and Bernice. In 1954, King became pastor of the Dexter Avenue Baptist Church in Montgomery, Alabama. In December 5, 1955 King began to be significant in the changing of the Black man’s way of life. The boycott of the Montgomery Bus was begun when Rosa Parks refused to surrender her seat on a bus to a white man on December 1st. Two Patrolmen took her away to the police station where she was booked. He and 50 other ministered held a meeting and agreed to start a boycott on December 5th, the day of Rosa Parks’s hearing. This boycott would probably be successful since 70% of the riders were black. The bus company did not take them seriously, because if there was bad weather, they would have to take the bus. The Montgomery Improvement Association (MIA)was established to co-ordinate the boycott. They had a special agreement with black cab companies, in which they were allowed to get a ride for a much cheaper price than normal. Blacks had to walk to work, and so they did not have time to do any shopping and therefore the sales decreased dramatically. On January 30, while M.L was making a speech, his house was bombed. Luckily his wife and baby had left the living room when the bomb exploded, but a black mob formed and was angry about what had happened, and Policemen were sent to the scene to control the situation, even though they were outnumbered. King, however, because of his strong belief in nonviolence, urged the crowd to not use their guns and to go home. What made Martin Luther King striking was his conviction on non-violence. He believed that this belief could give blacks a superior level of morality over whites. This ideology was important for his success in later years. As a result, it helped restrain the use of violence from  whites to blacks and vice versa. This philosophy was tested during the Montgomery bus boycott. Before the successful boycott, blacks used violence in order to protest racism. During the boycott, however, on both sides violence was not a measure to be taken. When someone bombed King’s home,the fact that violence was used against a nonviolent group made the idea of the black man’s cause more agreeable. B. GOALS In 1967, King became more critical of American society than ever before. He believed poverty was as great an evil as racism. He said that true social justice would require a redistribution of wealth from the rich to the poor. Thus, King began to plan a Poor People’s Campaign that would unite poor people of all races in a struggle for economic opportunity. The campaign would demand a federal guaranteed annual income for poor people and other major antipoverty laws. Also in 1967, King attacked U.S. support of South Vietnam in the Vietnam War (1957-1975). He regarded the South Vietnamese government as corrupt and undemocratic. Many supporters of the war denounced King’s criticisms, but the growing antiwar movement welcomed his comments. Dr. King and the SCLC organized drives for African-American voter registration, desegregation, and better education and housing throughout the South. Dr. King continued to speak. He went to many cities and towns. He was  greeted by crowds of people who wanted to hear him speak. He said all people have the right to equal treatment under the law. Many people believed in these civil rights and worked hard for them Dr. King believed that poverty caused much of the unrest in America. Not only poverty for African-Americans, but poor whites, Hispanics and Asians. Dr. King believed that the United States involvement in Vietnam was also a factor and that the war poisoned the atmosphere of the whole country and made the solution of local problems of human relations unrealistic This caused friction between King and the African-American leaders who felt that their problems deserved priority and that the African-American leadership should concentrate on fighting racial injustice at home. But by early 1967 Dr. King had become associated with the antiwar movement Dr. King continued his campaign for world peace. He traveled across America to support and speak out about civil rights and the rights of the underprivileged C. METHODS King’s civil rights activities began with a protest of Montgomery’s segregated bus system in 1955. That year, a black passenger named Rosa Parks was arrested for disobeying a city law requiring that blacks give up their seats on buses when white people wanted to sit in their seats or in the same row. Black leaders in Montgomery urged blacks to boycott (refuse to use) the city’s buses. The leaders formed an organization to run the boycott, and asked King to serve as president. In his first speech as leader of the boycott, King told his black colleagues: â€Å"First and foremost, we are American citizens. †¦ We are not here advocating violence. †¦ The only weapon that we have †¦ is the weapon of protest. †¦ The great glory of American democracy is the right to protest for right.† Terrorists bombed King’s home, but King continued to insist on nonviolent protests. Thousands of blacks boycotted the buses for over a year. In 1956, the United States Supreme Court ordered Montgomery to provide equal, integrated seating on public buses. The boycott’s success won King national fame and identified him as a symbol of Southern blacks’ new efforts to fight racial injustice. With other black ministers, King founded the Southern Christian Leadership Conference (SCLC) in 1957 to expand the nonviolent struggle against racism and discrimination. At the time, widespread segregation existed throughout the South in public schools, and in transportation, recreation, and such public facilities as hotels and restaurants. Many states also used various methods to deprive blacks of their voting rights. In 1960, King moved from Montgomery to Atlanta to devote more effort to SCLC’s work. He became co-pastor of Ebenezer Baptist Church with his father In the North, however, King soon discovered that young and angry blacks cared little for his preaching and even less for his pleas for peaceful protest. Their disenchantment was one of the reasons he rallied behind a new cause: the war in Vietnam. Although he was trying to create a new coalition based on equal support for peace and civil rights, it caused an immediate rift. The National Association for the Advancement of Colored People (NAACP) saw King’s shift of emphasis as â€Å"a serious tactical mistake† the Urban League warned that the â€Å"limited resources† of the civil-rights movement would be spread too thin; But from the vantage point of history, King’s timing was superb. Students, professors, intellectuals, clergymen and reformers rushed into the movement. Then, King turned his attention to the domestic issue that he felt was directly related to the Vietnam struggle: poverty. He called for a guaranteed family income, he threatened national boycotts, and he spoke of disrupting entire cities by nonviolent â€Å"camp-ins.† With this in mind, he began to plan a massive march of the poor on Washington, D.C., envisioning a demonstration of such intensity and size that Congress would have to recognize and deal with the huge number of desperate and downtrodden Americans. King interrupted these plans to lend his support to the Memphis sanitation men’s strike. He wanted to discourage violence, and he wanted to focus national attention on the plight of the poor, unorganized workers of the city. The men were bargaining for basic union representation and long-overdue raises. But he never got back to his poverty plans. 1. DISSENT Lawful Rights: While at seminary King became acquainted with Mohandas Gandhi’s philosophy of nonviolent social protest. On a trip to India in 1959 King met with followers of Gandhi. During these discussions he became more convinced than ever that nonviolent resistance and civil disobedience was the most potent weapon available to oppressed people in their struggle for freedom. He also used his speeches and demonstrations as tools to accomplish his goals such as: the â€Å"I Have A Dream† Speech, and the Montgomery Bus Boycott. D. ACCOMPLISHMENTS An African American Baptist minister, was the main leader of the civil rights movement in the United States during the 1950’s and 1960’s. He had a magnificent speaking ability, which enabled him to effectively express the demands of African Americans for social justice. King’s eloquent pleas won the support of millions of people–blacks and whites–and made him internationally famous. He won the 1964 Nobel Peace Prize for leading nonviolent civil rights demonstrations. In spite of King’s stress on nonviolence, he often became the target of violence. White racists threw rocks at him in Chicago and bombed his home in Montgomery, Alabama. Finally, violence ended King’s life at the age of 39, when an assassin shot and killed him. Some historians view King’s death as the end of the civil rights era that began in the mid-1950’s. Under his leadership, the civil rights movement won wide support among whites, and laws that had barred integration in the Southern States were abolished. King  became only the second American whose birthday is observed as a national holiday. The first was George Washington, the nation’s first president. King and other civil rights leaders then organized a massive march in Washington, D.C. The event, called the March on Washington, was intended to highlight African-American unemployment and to urge Congress to pass Kennedy’s bill. On Aug. 28, 1963, over 200,000 Americans, including many whites, gathered at the Lincoln Memorial in the capital. The high point of the rally, King’s stirring â€Å"I Have a Dream† speech, eloquently defined the moral basis of the civil rights movement. The movement won a major victory in 1964, when Congress passed the civil rights bill that Kennedy and his successor, President Lyndon B. Johnson, had recommended. The Civil Rights Act of 1964 prohibited racial discrimination in public places and called for equal opportunity in employment and education. King later received the 1964 Nobel Peace Prize. In 1965, King helped organize protests in Selma, Ala. The demonstrators protested against the efforts of white officials there to deny most black citizens the chance to register and vote. Several hundred protesters attempted to march from Selma to Montgomery, the state capital, but police officers used tear gas and clubs to break up the group. The bloody attack, broadcast nationwide on television news shows, shocked the public. King immediately announced another attempt to march from Selma to Montgomery. Johnson went before Congress to request a bill that would eliminate all barriers to Southern blacks’ right to vote. Within a few months, Congress approved the Voting Rights Act of 1965 By 1965, King had come to believe that civil rights leaders should pay more attention to the economic problems of blacks. In 1966, he helped begin a major civil rights campaign in Chicago, his first big effort outside the South. Leaders of the campaign tried to organize black inner-city residents who suffered from unemployment, bad housing, and poor schools. The leaders also protested against real estate practices that kept blacks from living in many neighborhoods and suburbs. King believed such practices played a major  role in trapping poor blacks in urban ghettos. King and the local leaders also organized marches through white neighborhoods. But angry white people in these segregated communities threw bottles and rocks at the demonstrators. Soon afterward, Chicago officials promised to encourage fair housing practices in the city if King would stop the protests. King accepted the offer, and the Chicago campaign ended. IV.COMPARING/CONTRASTING Washington kept his white following by conservative policies and moderate utterances, but he faced growing black and white liberal opposition in the Niagara Movement (1905-9) and the NAACP (1909-), groups demanding civil rights and encouraging protest in response to white aggressions such as lynchings, disfranchisement, and segregation laws. Washington successfully fended off these critics, often by underhanded means. At the same time, however, he tried to translate his own personal success into black advancement through secret sponsorship of civil rights suits, serving on the boards of Fisk and Howard universities, and directing philanthropic aid to these and other black colleges. His speaking tours and private persuasion tried to equalize public educational opportunities and to reduce racial violence. These efforts were generally unsuccessful, and the year of Washington’s death marked the beginning of the Great Migration from the rural South to the urban North. Washington’s racial philosophy, pragmatically adjusted to the limiting conditions of his own era, did not survive the change. Martin Luther King’s contributions to our history places him in this inimitable position. In his short life, Martin Luther King was instrumental in helping us realize and rectify those unspeakable flaws which were tarnishing the name of America. The events which took place in and around his life were earth shattering, for they represented an America which was hostile and quite different from America as we see it today. Black Americans needed a Martin Luther King, but above all America needed him. The significant qualities of this special man cannot be underestimated nor taken  for granted. Within a span of 13 years from 1955 to his death in 1968 he was able to expound, expose, and extricate America from many wrongs. His tactics of protest involved non-violent passive resistance to racial injustice. It was the right prescription for our country, and it was right on time. Hope in America was waning on the part of many Black Americans, but Martin Luther King, Jr. provided a candle along with a light. He also provided this nation with a road map so that all people could locate and share together in the abundance of this great democracy. We honor Dr. Martin Luther King, Jr. because he showed us the way to mend those broken fences and to move on in building this land rather than destroying it. He led campaign after campaign in the streets of America and on to the governor’s mansion – even to the White House – in an effort to secure change.

Capital investment analysis and inflation and capital investment analysis with taxation Essay

Inflation refers to persistent increase in price of goods and services. It is also referred to as average general increases in the price of goods and services. Prior to this time, there had been lots of argument amongst writers in finance on whether or not to ignore or include inflation when computing capital budgeting. The argument has always being that inflation affects both the discount rate and the cash flow hence the effect will always cancel out. During inflation shareholders will always demand for higher rate of return because inflation has a way of eroding the purchasing power of the shareholders but the impact of inflation on the company’s rate of return and the expected cash flow are not always the same. Shareholders are not likely to reflect the entire inflation rate on a single investment because of risk diversification strategy employed by most shareholders. Besides, inflation will not affect all the cash flows in exactly the same way. The impact of inflation on labour for instance will not be the same for material cost and cannot automatically reflect on selling price. Whichever way it is, the question is, How do we incorporate the effect of inflation in capital investment decisions? How do we adjust for inflation? Will the project still be worthwhile after adjusting for inflation? In analysing the effect of inflation in capital budgeting analysis two things should be taken into consideration. i. The effect of inflation on the discount rate – As inflation increases shareholders will demand for increased return to compensate for the reduction in the value of their capital. So there will be increase in the minimum return required by an investor. ii. How to take account of the impact of inflation on future cash flows. There are basically two types of inflation: i. General inflation – this is an increase in the average price of all goods and services in an economy. General inflation affects both the discount rate and the cash flow hence it should be properly estimated. Changes in consumer price indexes are used as a measure of general inflation in Nigeria. ii. Specific inflation – refers to changes in prices of the various components that make up the project under consideration. Various components such as sales prices, labour cost, variable cost etc. Specific inflation affects only the cash flows of the project. The treatment of specific inflation should be detailed as possible. Money Cash flow and Real Cash flow In an inflationary period there is a difference between N10,000 cash and goods and services worth N10,000. The first is the money cash flow while the later is real cash flow. Money Cash flow refers to the actual amount of cash flows in nominal term. To arrive at the money cash flow we adjust each item by its specific rate of inflation. Real Cash flow on the other hand refers to purchasing power equivalent of the actual amount of cash flows. To arrive at the real cash flows we deflate (i.e. discount) money cash flows using the general rate of inflation. In project appraisal, general inflation is usually assumed to be the same throughout the project’s life. It becomes easier to analyse the impact on both cash flows and the discount rate. However specific inflation rate need not be the same throughout the project’s life. Money Cost of Capital (MCC) & Real Cost of Capital(RCC) MCC – Measures the actual discount rate in terms of the actual money. That is, it is the discount rate in nominal terms. RCC – Measures the discount rate in constant price level terms. Return on an investment are usually based on expected returns. The anticipated rate of inflation will be reflected in required rate of return for a project. This relationship has long been recognised in financial economies and it is referred to as fisher’s effect. It is expressed as (1+m) =(1+r)(1+I) Where m= Money cost of capital R= real cost of capital I = General rate of inflation From the equation above, if ‘r’ & ‘i’ are given, m could be computed as: M=(1+r)(1+i)-1 If m and I are given the r can be calculated as r = – 1 If m and r are given, then i can be calculated as follows i = – 1 Rules to follow using MCC & RCC 1. Cash flows in money or nominal terms should be discounted at money or nominal cost of capital 2. Cash flows stated in money terms can be converted to real cash flows by discounting at the general rate of inflation. The real cash flows should then be discounted at real cost of capital. 3. Discounting money cash flow at the money cost of capital and real cash flows at the real cost of capital will give the same NPV for a project. 4. The specific rate of inflation should be effected on specific cash flow only. The cash flow arrived at should then be discounted at the relevant cost of capital which in most cases is the money cost of capital except otherwise stated. 5. Money cash flows should be discounted with money cost of capital and real cash flow should be discounted with the real cost of capital. Raze Ltd is considering a project costing N50,000. The project is expected to have a life of 4 years with a residual value of N4,000. Annual cash revenue from the project is expected to be N35,000 in year 1 rising by 6% per annum for inflation. Running cost are expected to be N15,000 in the first year of the project but would increase by 11% per annum because of inflating labour costs. The general rate of inflation is expected to be 8% and the company’s money cost of capital is 18%. Advice the company on whether or not to accept the project. Rex Ltd have been considering a 5yrs project costing N3m which on an initial estimate would earn N1.1m per annum in contribution without incurring any additional fixed cost but with a nil residual value at the end of year 4. Cumulative discount rate at 15% for 5years is 3.352. The company’s director believes that the project should be undertaken because its NPV was N687,200.00 However, further investigation into the cash flow reveals the following. a. The contribution consists of annual sales of N2.7m and variable costs of N1.6m for 1million units of sales per annum. These are the expected money values in year one. b. The sales would be made through a single distributor, who has asked for a fixed selling price of N2.70 per unit for 3yrs after which prices could increase by 18% for year 4 and held constant for year 5 c. Variable costs of N1.60 per unit in year one consists of material cost of N0.80 which are expected to increase by about 5% per annum and labour costs will rise by an expected 10% per annum for each year because of existing wage agreements with the trade unions concerned and a shortage of skilled labour for the work.

Summary We have looked at the impact of inflation in capital investment appraisal. Inflation refers to the persistent increases in prices of goods and services thus affecting the financing needs if the organisation as well as its cost of debt and WACC. Inflation is treated in capital investment appraisal by discounting inflated values of future cash flows at the money cost of capital or real cash flows at real cost of capital. Review question Idi araba town council plans to build a bridge over the local river to replace the existing ferry service. Building will start in one year’s time, that is 2006 and will take 4 yrs. It has planned to sub contract the building work to a major construction company and the best tender will involve the council in a cash expense of N10m at the start of building and further payments of N5m each year until 2010 once completed, the annual maintenance cost for the bridge will be N1m per annum according to today’s prices; the annual cost is expected to rise with the general inflation rate of 7% p.a. In addition, a major overhaul is expected to be required after the first 15years of use, this will comprise N10m of material plus wage costs of a further N10m in current prices. Material prices are expected to rise with the general rate of inflation for the next 16years and then remain constant; wage cost is expected to increase by 6% over the general inflation rate for the next 3years and then increase in line with general prices. The market interest rate the council consider relevant for the whole life of the project is 17.7%. You can assume that for calculation purpose the life of the bridge is infinite. The expected use of the bridge is 20,000 vehicles per day and toll charge is expected to increase in line with general inflation. Required a. Calculate minimum toll charge in the first year of operation necessary for the bridge to break even over its life, and explain your treatment of inflation. Note: Assume all annual cash flows arise on the last day of the relevant year. b. What other factors do you think the council should consider when deciding upon the toll charge? Note: The statement that â€Å"in addition, a major overhaul is expected to be required after the first 15yrs of use† should be interpreted to mean at the end of the first 15years of use (i.e. year 20.5 +15) (ICAN , 1993) Capital Investment Analysis and Taxation Tax is an important factor to consider when computing capital investment appraisal because of its implications on cash flows. Capital investment appraisal is based on after tax incremental cash flows arising from the project. Thus, when appraising the viability of a project tax that has to be incorporated and then discounted at the relevant cost of capital. Corporation tax This is charged on the profit made on projects that is positive cash flows and then discounted at the appropriate ruling rate. Currently in Nigeria, it is charged at 30%. It is usually charged on a preceding year basis because tax is expected to be remitted 6-11 months after the end of the period in which profit were earned. In capital investment appraisal we assume a year lag for corporation tax payment, that is, tax on taxable profits made in year one will be deemed payable in year 2 except otherwise stated. Also, when losses are made on a project the losses are used to reduce tax liability hence, it is treated as tax benefit. The amount by which tax is reduced is equivalent to cash inflow to the project. Investment Incentives – This is given to encourage investment in fixed assets. The main types include investment allowance and capital allowance. Investment allowances – are receivables which should be brought into the project appraisal in the period in which they are receivable. They are use to reduce the tax liability. Capital allowance- is available to reduce a tax liability if a business is carried on and it has a balance of qualifying capital expenditure. The reduction is treated as cash savings. Capital allowance could be treated on a straight line basis or a reducing balance basis. In Nigeria it is claimed as initial allowance and annual allowance. The Nigerian law permits a company to leave at least N10 in its book as written down value for an asset that is not yet disposed by the company. The Nigerian law also restricts the capital allowances a company can claim in any year of assessment to a certain percentage of the adjusted profit so that companies that have made profit can always increase their tax liability. On disposal of an asset no capital allowance can be claimed in the year of disposal. When disposal is finally made, the difference between the proceeds on disposal and tax written down value treated as: i. A balancing charge – if the sales proceeds exceed the tax written down value. ii. A balancing allowance if the tax written down value exceeds the sales proceeds. Assumptions on Investment allowance and capital allowance claims Two possible assumptions can be made on when to deduct capital allowance claims i. We can assume that the first claim is set – off on profits that occur in year one and it is deductible in year 1 ii. The most acceptable by examiners and in practice is to assume that the first claim occurs in year one and the tax savings occur one year later that is, year 2. Illustration 1 A company purchases a machinery at a cost of N10,000 in respect of a project which has a life of 5years and a residual value of N500. Calculate the capital allowance on a straight line basis that will be used to reduce tax payment in each year of the project. The initial allowance is 50% while the annual allowance is charge at 25%.

Transport Across The Fermentation Tank Engineering Essay

Agitators in fermenter play a major function in blending the medium. Agitation in fermenters improves heat and mass conveyance across the agitation armored combat vehicle. Mechanically moved fermenters are well-suited for usage with shear-sensitive agitations that require good O transportation and majority commixture than the conventional air lift fermenters. Fermenter, in biotechnology is usually explained as a container where the host cells incorporating the recombinant Deoxyribonucleic acid are grown. In simple footings fermenter is an setup which maintains optimum conditions for the growing of micro-organisms which are used in big scale agitation in the production of enzymes and other chemicals. Basically the fermenter consists of a fomenter either bottom driven or top driven. The most normally used is the fermenter with a top-drive assembly because of its easiness of operation, orderly design, dependability, and hardiness. Agitators in fermenter play a major function in blending the medium which is invariably aerated which means supplying efficient mass exchange in footings of gas stage and liquid stage ( blending ) by providing nutrition and taking away the metabolites. Mass transportation is enhanced by agitation from the headspace to the majority of the liquid ; it creates less anaerobiotic environment ( microaerophilic ) for agitation, farther decelerating down the agitation clip and upseting the ecological equilibrium. The chief intent of agitation usually are intermixing of two mixable liquids, fade outing solids in liquids, scattering a gas in a liquid as all right bubbles, suspending of all right solid atoms in a liquid and to increase heat transportation between the fluid and a spiral or jacket in the vas wall. Agitators must able to make self-cleaning and must forestall monolithic subsiding. Agitation provides practical benefits peculiarly in agitation vass with hapless heat-transfer characteristics. It improves heat and mass conveyance across the agitation armored combat vehicle. By bettering those agitation can cut down temperature heterogeneousness and destroy concentration gradients during agitation, supplying a more unvarying microenvironment for microbic growing. This has positive economic and merchandise quality-related benefits like cut downing the agitation clip, and better standardising process public presentation and merchandise properties. Most of the chemical and processing industries depend on effectual agitation and commixture of fluids for most operations. Generally agitation refers to coercing fluid by mechanical agencies to flux in a peculiar form like circulatory or other pattern inside a vas. Blending normally involves scattering two or more separate stages such as a fluid and a solid or two fluids with one another. Agitation besides has disadvantages peculiarly in industrial agitation procedures. Agitation may interfere with the gel-formation procedure, a cardinal quality property in house yoghurt ( Kristo et al. , 2003 ; Lee and Lucey, 2004 ) and agitation during agitation would suppress the lactic acid formation involved in the procedure ( Driessen, 1998 ; Early, 2000 ) , accordingly widening the agitation clip and perchance changing the quality, there is a possibility of it favoring the incorporation of air into the system, interfering with the agitation kineticss, an anaerobiotic event. Agitators have different parts and all the traveling parts can be made unapproachable by enveloping underneath the vas, therefore doing it a safer piece of setup. There are different sorts of fomenters with or without motor driven. With the motor belt goaded fomenter any spillage can be avoided by straight falling onto the motor since it is non sited straight below the fomenter shaft. Double mechanical seal in the fomenter is necessary to guarantee that the medium does non leak out at the shaft lodging. Depending upon blending demands the agitation shaft will be provided with two or three impellers, each with four or six blades. It is of import that the exterior coating of the fomenter should fit that specified for the vas. Bigger impeller diameters result in shorter blend clip and lower extremum shear. Though it has benefits it is besides necessary to see the higher cost, increased quiver and larger run-out and more robust design demands associated with larger diameter impellers and greater fluid forces. Orientation and size of fomenters varies with fermenters. Scale-Up: In production conditions, either the fomenter revolutions per minute is varied or the impeller is changed to obtain similar blending clip. These impellers can run at much higher tip velocities since they convert a bigger fraction of their power input into unstable pumping instead than shear. There are two chief occupations of fomenters in a cell civilization. First is to obtain the coveted O and C dioxide mass transportation by bring forthing adequate shears which can be characterized by gas mass transportation effectivity and the 2nd is to maintain the vessel well-blended to minimise fluctuations in temperature, pH and linear concentration. The cells inside should be exposed to higher mechanical force or thermic force and or emphasis. The peak shear rate must be kept low plenty to avoid cell harm or emphasis. Bigger the mass transportations is better, because cut downing the fraction of O in the sprinkle gas or flow of sprinkle gas lowers the operating cost and reduces cell harm in certain cell lines. Deluging occurs if the fomenter turns excessively easy for the gas rate and if the gas burden exceeds the implosion therapy point consequences in lower mass transportation. Doppler velocimetry is used to mensurate the shear produced by an fomenter utilizing a optical maser beam to scan the instantaneous speed at points throughout the vas. The fomenter is preferred to be top mounted which makes it easy to take it during go oning operation and to avoid voidance of fermenter during care work on the fomenter. Airlift type and automatically stirred/ agitated fermenters are widely used in bioprocessing. Airlift fermenters are utile where there is necessity of soft agitation and low cost O transportation and in comparatively less syrupy fluids while the mechanical fomenter is works more expeditiously for higher-viscosity fluids. Normally used fermenter which utilizes mechanical agitation rules chiefly uses radial flow impellers during the agitation procedure. Top-mounted fomenters are common in smaller vass where they are easier to seal, but do require longer shafts and larger diameter to command run-out and quiver while in big scale production underside mounted fomenters are by and large used where they need shorter shafts of 3m or less. The latter type is easy to manage since the shaft are of smaller diameter and they are cost effectual. It is easy to take the mechanical seal. Agitator must be mounted either on an angle or offset from the vas Centre line when the vas does non hold baffles. Baffled vass with centre top-mounted fomenters are more common. General chromium steel steel fomenter with high opposition to corrosion A mechanical fomenter is driven by an explosion-proof motor ( electric motor ) , it has a shaft and cogwheel coupled to a cogwheel box that drives the impeller shaft and may even hold immersed bearings if the shaft is really long. The impellers ( turbines ) transform mechanical power into unstable circulation or agitation. The aim of the properly designed mechanical agitation system are unvarying suspension of solids, appropriate application of shear, homogeneous fluid belongingss throughout the system and economical application of applied power. The rotating parts in a mechanical fomenter are capable to change by reversaling emphasiss that may ensue in metal weariness, failure of shafts, seals and fomenter blades particularly when the environment is temperature specific. Experimental setup that consists of jacketed 50 milliliter reactor ( Parr, theoretical account 4843 ) with mechanical agitation. Fermenter with Mechanical Agitation ( www.scielo.br/scielo.php? script=sci_arttext ) During the commixture procedure, the mechanical fomenter plants by turning the mechanical power into thermic energy where the energy ( temperature ) is introduced non-uniformly into the volume. This produces harmful effects to the life beings and agitations in the procedures, which exist merely in limited temperature scope. The commixture can be improved by increasing rates of aeration and mechanical agitation. However, the influence of aeration rate on blending clip was most outstanding merely under conditions of small or no mechanical agitation. The independent agitation reduces the demand for long flow channels besides maintains efficient blending irrespective of merchandise throughput or viscousness. The fermenter design becomes more complex when mechanical agitation is applied for blending nevertheless it offers considerable advantages in footings of versatility and public presentation. Strong axial commixture is one of the less desirable characteristics of mechanical fomenter. There are some major disadvantages in utilizing mechanical fomenters such as unsystematic commixture, where it shear fluid and impel it around the commixture vas. High-turbulent and dead zones are formed during blending which consequence in un-uniform nutrition supply to cells, due to mechanical force produced by sociable ‘s beater the microbic cells may decease. Overheating is formed on the terminals of sociable ‘s beater countries ( micro zones ) which are besides destructive for cells. Mechanical fomenter has merely a motor ; it may hold a provender pump, nevertheless. Mechanical fomenters can non be made on plastic if necessary. Top-entering mechanical fomenters typically require a befuddled armored combat vehicle and it can non blend the armored combat vehicle when it ‘s less full. More dead musca volitanss are formed whilst utilizing a mechanical fomenter. Mechanical fomenter typically needs one impeller diameter of clearance near the armored combat vehicle to supply energy during solid suspension. A mechanical fomenter by and large uses less energy for liquid blending in armored combat vehicles smaller than 3 thousand Defense Intelligence Agency, but during solids suspension, liquid blending and gas/liquid contacting in large-volume ( over 1,000 gal ) fermenters with mechanical agitation costs higher. The additive liquid speed in the downcomer increased with the increasing velocity of the fomenter but was non sensitive to the aeration rate, except in the airlift manner of operation ( N=0 revolutions per minute ) . The fact that the liquid speed varied small with aeration rate in automatically agitated operation whereas at a changeless agitation speed the commixture clip declined with increasing rate of aeration suggests that under given conditions of mechanical commixture, the gas bubbles lifting through the fluid were an of import cause of blending. Bubbling frequence additions with increasing aeration rate and the bubbles lifting relation to the liquid carry in their aftermaths a certain sum of fluid. As celebrated earlier, the consequence of mechanical agitation on blending clip was pronounced merely at comparatively low aeration rates. At higher aeration speeds ( UGr?0.04 ms?1 ) , lifting bubbles seemed to the dominant cause of the commixture Depending on the strength of the mechanical agitation, air sparging of the riser zone may or may non better the commixture public presentation. At sufficiently high aeration rates ( UGr?0.04 ms?1 ) , the usage of mechanical agitation during commixture has lesser importance. Air lift agitation utilizes compressed air to continuously recycle slurry. Consisting of simple piping, air lift agitation requires no traveling parts and negligible care. The consequence is homogenous slurry. Mechanical impeller will shear certain cells that are less delicate. For the ground the mechanical fomenter, which causes unwanted emphasis and perturbation is removed from the medium. About 70 % of consumed power is used for get the better ofing the defying force ( in a medium ) with mechanical fomenters. In this connexion mechanical power is automatically turned into thermic energy and therefore consequences in excess harmful warming of the civilization. Therefore this excess warming must be removed from the fermenters. In Airlift Fermenters the civilizations are both aerated and agitated by air bubbles introduced at the underside of vass. The vas has an inner bill of exchange tubing through which the air bubbles and the aerated medium rise since aerated medium is lighter than not aerated one which consequences in commixture of the civilization every bit good as aeration. The air bubbles lift to the top of the medium and the air passes out through an mercantile establishment. The cells and the medium that lift out of the bill of exchange tubing move down outside the tubing and are recirculated. O2 supply is rather efficient but scaling up nowadayss certain jobs. These sorts of fermenters are now used for production of monoclonal antibodies. The contents are pneumatically agitated by a watercourse of air and or sometimes by gas. In add-on to agitation, this watercourse besides has the of import map of interceding exchange between the gas stage and the medium ; O is normally transferred to the liquid, and in some instances metabolic merchandises are removed through exchange with the gas stage. Air lift fermenters eliminate the possible grinding jobs encountered in agitated fermenters. Due to take down shear force the extents of cell desorption from atom surfaces would be less as compared to agitated systems while utilizing solid substrates. Air lift fermenters are energy efficient and easy to run, and require merely tight air for aeration and agitation and extinguish the demand of mechanical agitation. Oxygen transportation efficiency is higher than mechanical agitated fermenter. Lab or pilot workss can non easy air trial because it requires long bubble opposition clip with minimal wall retarding force. The short vass where mechanical agitation is required for good agitation public presentation compared to air agitated fermenters. If the vas has chilling spirals the commixture is good from top to bottom. Air agitated fermenters exist in industry today for a broad scope of merchandises. Air-lift stirred without mechanical seal The chief advantages in utilizing air lift fermenters are improved asepsis because of no top or bottom come ining agitation shaft, building of really big fermenter is possible because the design is non limited by motor size, shaft length and its weight, infrigidation demands are reduced 20 to 35 % because of no mechanical agitation, cheaper fermenter design. No care of motors, gear boxes, bearings or seals. The air agitated fermenter is a feasible blending power unit like a variable velocity thrust with no motor and drive noise. Air compressors can be steam driven to cut down power cost and go on to run during power outages in big workss with minimum power coevals for controls. Air-lift fermenter exhibit lower rates of O mass transportation and commixture compared to agitated bioreactors and therefore their usage for industrial production of enzymes could ensue in O lack of the agitation broth and unequal majority commixture. On the other manus, compared to other fermenters, air-lift fermenters have a simpler design, have a lower capital and operating costs and exhibit a lower shear environment. For the latter ground, air-lift fermenters have been used successfully in agitation of shear sensitive micro-organism in high viscousness. The chief disadvantages are because of weak blending they do non ever suit for civilizations with active critical maps. They do n't hold intensive nutrition supply and do n't take away the metabolites intensively. Sudden alteration of force per unit area will do the air bubbles drifting to the surface and in bend devastate sensitive cells. It besides produces abundant foaming. The application of chemical froth ledgeman makes quality of concluding merchandise worse and the procedure more expensive. These disadvantages are connected with hurt of cells and micro-organisms during the procedure of the medium commixture, deficient strength of mass exchange, formation of high-turbulent and dead zones, high power ingestion, low features when they works with syrupy fluids. This is a table demoing the chief advantages and disadvantages of air lift and mechanical fomenters in fermenters: Mechanical Air lift

Bishop’s “The Fish” Poetry Response Essay

In the poem â€Å"The Fish,† Elizabeth Bishop uses a fish as a symbol to express the theme of life and experience. The poem by itself has little structure to it. There are no apparent rhyme schemes, nor any clear meters. However, Bishop uses very powerful diction and ideas in the poem, forcing the reader to think and relate it to a greater aspect of his/her own life. The persona has a very mature and serious tone, and some gloomy element to his/her mood. The poem uses a significant amount of imagery. Descriptions like â€Å"brown skin hung in strips† and â€Å"fresh and crisp with blood† are common throughout the poem. The reader can almost see the fish on the boat, waiting for its life to end. Bishop also uses a plethora of colors in the poem. Colors include: â€Å"brown skin,† â€Å"green weed,† â€Å"dramatic reds and blacks,† â€Å"yellowed,† â€Å"green line,† and it also contains the combination of all the colors in the sp ectrum as â€Å"rainbow, rainbow, rainbow!† was repeated in the poem. The Colors are there to enhance the imagery and also work archetypically to express the mood of the poem. When the persona states that the â€Å"oil had spread a rainbow,† it should indicate that tears has formed in her eyes, splitting the light into its spectrum, as she also mentions â€Å"sun-cracked thwarts.† At the end where â€Å"everything was rainbow,† tears had flooded her eyes, blurring every sight and showing only splashes of colors all around. At the beginning of the poem, the persona notes that the fish did not fight at all. She describes the fish as â€Å"battered,† â€Å"homely,† but yet â€Å"venerable.† Later she discovers that the fish has fought many battles, and the broken lines are signs of victory. She realizes the fish is not just something that gives up without a fight, but it is something that has just fought too long and is tired of it. The persona realizes what the fish has gone through and instantly gains respect and condemnation for it. She lets it go. For writing this poem, the author might have a family member that was suffering from a disease. After a long time of painful struggle, that member finally gives up because he/she saw through the value of life, just like the fish. However, there is one thing that I disagree with the persona, because she states the fish has â€Å"a five-haired beard of wisdom.† In my opinion it should be â€Å"five-haired beard of stupidity† since the fish cannot learn from its past.

9.Define the concepts of risk and threat and discuss the statement Can Essay

9.Define the concepts of risk and threat and discuss the statement Can you have Risk without Threat - Essay Example The whole idea can be also defined as: the ability of a certain system to protect all its information with respect to discretion and veracity .Another point to ponder upon is Note that the scope of this second definition includes system resources, which include CPUs, disks, and programs, in addition to information. A brawny security protocol addresses all three of these areas. Take, for example, Netscapes SSL (Secure Sockets Layer) protocol. It has enabled a detonation in ecommerce which is really about conviction (or more precisely, about the lack of trust). SSL overcomes the deficiency of conviction between transacting parties by ensuring discretion all the way through encryption, veracity through checksums, and substantiation by means of server certificates (see Chapter 15 of Unix System Security Tools). Access control -- Make sure that users admittance is only to those resources and services that they are permitted to access and that competent users are not denied access to services that they lawfully expect to receive These supplementary rudiments dont neatly put together into a particular definition. From one perception, the concepts of seclusion, discretion, and security are quite distinct and possess different attributes. Privacy is a property of individuals; discretion is a property of data; and security is a property assigned to computer hardware and software systems. From a realistic perspective, the concepts are interwoven. A system that does not sustain data discretion or entity privacy could be tentatively or even precisely "secure," but it probably wouldnt be wise to systematize it anywhere in the real world. Risk avoidance -- A security essential that starts with questions like: Does my organization or business engage in activities that are too risky? Do we really need an unobstructed Internet connection? Do we really need to computerize that secure business process? Should we really standardize on a
