Reconstruction After the American Civil War Essay

The civil war is considered by many the most important war that our country has endured. During the 5 year Civil War, not only did 620,000 men die, but our nation was left in ruins. It was necessary that our country be rebuilt from bottom up. Abraham Lincoln, said to be the brightest president of his time, had plans and ideas for reconstruction. Unfortunately, these plans were failed to be put in place due to the fact of his assassination on April 14, 1865. Throughout some of the most politically tough years our nation has experienced (1865-1877) lousy presidents were elected, plans and bills failed and succeeded, and struggles with civil rights were prominent everywhere. The United State’s hopeful plans for reconstructing and reuniting slowly faded until it was all gone The most important part of reconstruction would probably have to be the beginning, or where it all started. Reconstruction of our nation began unofficially in 1863 with Lincoln’s 10% plan. Because Lincoln wanted a reunited nation as easily and quickly as possible, he entailed that only 10% of the confederates in each state would have to swear allegiance in order for the state to be accepted back into the union. Because of the small number of confederates needed to swear allegiance, the radical republicans in congress were angered and proposed the Wade-Davis Bill. The Wade-Davis bill was intended to make congress responsible for reconstruction rather than the president, and also stated that the majority (not 10%) would have to swear allegiance in each state to be re-accepted into the union. For the good of the united states, not for selfish reasons, Lincoln vetoed (or declined) the bill. Because Lincoln was assassinated, the rest of his plans and hopes for reconstruction were n ever put to use, and his vice-president, Andrew Johnson, took the Presidential role. As reconstruction continued on, it brought many major achievements that greatly benefited our country. One of the greatest accomplishments of reconstruction was the Fifteenth Amendment. The Fifteenth Amendment stated that everyone has a right to vote no matter what â€Å"race, color, or previous condition of servitude† was. Because many whites didn’t like this, they wouldn’t cooperate with the amendment and would go as far as using violence to make blacks not vote. Because of this congress used the Enforcement Act of 1870 which entailed that federal governments would be able to punish those that were causing problems for the African Americans. Going along with the fifteenth amendment, reconstruction brought another achievement, a new life and society for former slaves. Supported by the government, former slaves were able to create new lives for themselves. Although it took hard work and dedication, African Americans were able to create schooling systems, churches and volunteer groups and fight against segregation. Former slaves were able to reunite with their families, and blacks were even finally allowed a spot in politics. The final greatest achievement of reconstruction was reuniting our country. Alabama, Arkansas, Florida, Louisiana, North Carolina, South Carolina, Tennessee, and the other four states all re-entered the union by 1870. By originally initiating reconstruction, this is what Lincoln was shooting for. Although they still had political and economic differences, they were once again a reunited nation. With every great movement and political plan, lasting effects come along with it. During reconstruction many things were accomplished, which means that our nation was faced with many positive and negative effects. Some of the positive effects included new opportunities for the common public and former slaves. For example, the common public was presented with its first public school system, new roads and railroads, as well as orphanages for children and institutions for the mentally ill. One of the negative effects of the war was the physically and economically drained south. After the war, the south was in extremely poor physical condition and most everything had to be either rebuilt or restored. This was going to cost sufficient amounts of money that the south did not have. To get the money, the taxes rose and the wages lowered. Many people were without family members that died in the civil war, and the south’s population had decreased drastically. Another lasting effect that reconstruction left on our nation was a dent on the farms and plantations in the south. Many farms and plantations in the south had been ruined. Poor whites and African Americans were at disagreement with rich whites on what the farm land should be used as. Rich whites wanted to restore the plantation system and poor whites and African Americans wanted to create small farms and subsistence farming. Labor was also down. With many men dying in the war, not as many people were left to work on the farms. When the plantations were reopened, many African Americans and poor whites worked on the plantations in exchange for housing, food, clothing, etc. Many good and bad effects were left on our nation from reconstruction. Although reconstruction was a good recovery point for our nation, it was slowly ended in 1877 for a collection of reasons. One of the largest problems was whites inflicting violence on African Americans to prevent them from exercising their rights. During reconstruction, Americans struggled with anti-black radicals such as the Ku Klux Klan. They destroyed buildings, personal property, harmed the African Americans, and even went as far as killing them. The goal of the Ku Klux Klan was to restore white supremacy. By 1880 terrorist groups had restored white supremacy in the south. Along with terrorist groups, political troubles were also in the nation’s way. General Ulysses S. Grant was elected president in 1872. Because Grant was inexperienced, he brought his friends into high positions and many scandals resulted. Because of all of the scandals, many people became irritated and more conflict arose. Last but not least, the United States was experiencing economic turmoil. The panic of 1873 was one of the main reasons that focus was turned away from reconstruction. A man named Jay Cooke invested a grand amount of money in railroads and not enough investors bought shares, causing Cooke to spiral into debt. Because of this Cooke’s banking firm (largest in the nation) went bankrupt. Many small banks and businesses closed and the stock market closed. Millions lost their jobs. Because of this five year depression, the focus of the country was turned away from reconstruction. Reconstruction lasted a solid 13 years that were filled with many great improvements and countless lasting effects on our country. While enduring many severe losses and challenges brought on by the Civil War, the United States pushed through and reunited. We will always be affected by this era in our country’s history. Throughout many failed presidencies, failed and passed bills and movements, and continuous struggles with civil rights, America became the country it is tod ay. From the achievements to the collapse of reconstruction, I believe it was completely necessary and left many lasting effects, good and bad, on our country.

Medusa by Carol an Duffy, Loads of Mistakes. Essay

‘The Worlds Wife’ in which Duffy gives a voice to female characters that may have been ignored throughout history. The poems are presented through the point of view of these women and in many cases it is the first time that we, as an audience hear their side of the story, rather than a story that has been told for them. Medusa matches the other poems in this anthology as Duffy presents Medusa as she sees herself but she is still shed in a negative light, which she willing presents to the reader as she is perversely pleased by it. Duffy uses clever diction and sentence structure to add to the representation of the persona as well as punctuation and techniques, most significantly rule of threes, to effectively display the persona and the themes of growing rage, stone, revenge and self absorption. Duffy wastes no time in jumping into Medusa’s perspective as the first line proves. The poem starts on a bitter note with â€Å"a suspicion, a doubt, a jealously† which is significant for numerous reasons. Firstly, the diction of jealousy alone is important because it suggests the breeding of ill feelings at the start of the poem which reflects how Medusas life as a monster began in much the same way. Also, the rule of three contains nouns that build on each other are progressive as Medusa graduates from a suspicion to as doubt and then becomes jealous, an idea which is also suggested by the caesura of commas rather than full stops, indicating that the nouns flow together and are linked rather than being separate or distinct. The first line is organized in a way that makes the growth of negative feelings evident which foreshadows the growth of rage and hate expressed later in the text while the progressive rule of three effectively foreshadows the continued use of the same technique throughout the poem. The growth of negativity is supported again in the following lines which imply that Medusa’s feelings were so strong as to be represented physically through the turning of the hairs on her head to filthy snakes. The snakes are obviously a tangible representation of the growth which Duffy emphasizes all the more the length of the line. Being longer than ever y of line of the poem is it a clear, visible reflect of the actual growth of the snakes that represent Medusas anger. The first reference to the theme of stone is made in the second stanza, in which the persona describes her lungs as â€Å"grey†, which indicates that Medusa’s lungs that support her life, are hardened, colourless and decayed, replicating her emotions and reflected the effect that she has on living being which is to turn them to stone. While the imagery of the grey lungs suggests lifelessness, it is immediately contrasted by the image of â€Å"yellow fanged† which is a link back to the snakes that are alive and thriving on her head. The combination of the two images suggests that Medusa herself is dead but possesses life because she is fully embodied by the snakes, and everything that they represent, an idea that is backed up by her having yellow fangs as if she is now a snake, not human. Stone is suggested again in the second stanza through the metaphor of â€Å"bullet tears† which relate to the hardness of stone and imply that Medusa’s emotions murder or kill as bullets do, which is evident later on in the poem. The first sense of Medusa’s feeling of self importance are apparent at the end of this stanza with the rhetorical question of â€Å"are you terrified†, suggesting her pride in the monstrosity that she is viewed as and also the fact that it is immediately followed by an answer in the form of a command implies that the actual answer of the man that she is talking to is unimportant and she is indifferent to it which emphasizes her own self importance. However, the man, the â€Å"Greek God† is displayed with some importance, though meager compared to hers, as he manages to catch her eye. It is him that she loves and since he has been special enough to attract the attention of one as high as medusa he should be scared because her attention is one him rather than ignoring him and also that fact that he catches her eye is fitting because it is exactly that that will turn him to stone. The third stanza has a link back to the first in â€Å"I know you’ll go, betray me†. Both suggest Medusa’s lack of trust and bitterness by how easily she passes negative judgment on the man before he has a chance to act as such. This negative outlook may be a partial cause to Medusa’s selfishness, leading her to believe that nothing is worth her time. Her selfishness and lack of caring about even those that she supposedly loves is displayed through the final line in this stanza: â€Å"so better by for me if you were stone. † It is only what is better for her that matters which again puts her, the only moral of the Gorgons, on a pedestal above a Greek God. In the next three stanzas the tone changes from a passive and indifferent statement of facts to an active narration of her deeds that emphasize her rage, especially as she draws particular attention  to her actions. I will look at the following three stanzas collectively as there are techniques spread through them. Medusa’s hate and spite become obvious now and grow rapidly, which links back to the first line with the progressive rule of three. The same technique is used again in these three stanzas though more disjointed than before. The intensity of medusa’s gaze increases in the first line of each stanza form glanced to looked to stared, with is another progressive rule of three as one thing builds on another and it replicates the expansion of her rage through time. The growth of medusas hate is also suggested through the size of the stone that she creates. Starting with a tiny pebble from a bee and progressing to a boulder metaphorically implies that as her hate increases, so too do her destructive powers as the two are directly linked. To support this notion, another progressive rule of three flows through the three stanzas. The way in which the stone drops from the air increases with Medusa’s rage as well with verbs of increasing severity: â€Å"fell, spattered, shattered† which is another clever technique that Duffy uses to emphasize and enforce the previous two points. Now focusing on only the sixth stanza, the verb â€Å"stared’ holds significance aside from the rule of three that it forms; â€Å"stared† again emphasizes medusas opinion of self importance as she spare the animals a mere glace or look both devotes far more time and intensity to herself because she is of more significant. Also, while everything else that she looks at turns to stone, she does not when she stares at herself which implies that she cannot be converted because she is already hard and cold as stone at heart. Following on in the sixth stanza, medusas anger seems to reach its epitome and its colossal size is represented by the imagery of the dragon, fire and the mountain. The three final lines of this stanza can be interpreted in two ways. There is the obvious link to the metamorphosis that takes place between animals and stone in the previous two stanzas which implies that medusa looked at the dragon and made it a mountain. However, unlike the other examples of medusa turning animals to stone, the dragon is separate from the mountain by a full stop where previously it has been a comma. The deliberate change in the punctuation pattern separates the dragon from the mountain while, suggesting that when Medusas stares into the mirror she see that dragon that is herself. If medusa is metaphorically a dragon then the growth of her anger is again insinuated because previously in the poem she was presented as a snake but now towards the end she has grown into a larger and fiercer reptile. While the dragon may be medusa the mountain represents her rage as it is an indication of its massive size while the fire goes to support the implication of raw anger. In stanza 7, the tone again changes back to how it was at the start of the poem with medusa addressing the greek god again. Medusa appears to be justifying her hate towards the man in this stanza by stating that he has a shield for a heart and a sword for a tongue. The metaphors suggest that the man never really loved medusa as she loved him and that he played her, finally hurting her with is words and his betrayal which is why she seeks revenge. Though medusa may blame the man for what she has become, she appears to like herself better the way she is now which is indicated through the last three lines of the poem. A content, menacing and proud tone accompanies look at me now as if medusa likes who she is. Also, since what she is now is contrasted to how she was when she was young, the is a suggestion that while she was young and naive she was ignorant to how she should be, where as now the she is older she knows that she is as she should and thinks highly of herself for it. The importance of what she is now is emphasized by the fact that the line forms a stanza on its own. Through most of the poem, beautiful things are being turned to rigid, lifeless stone which is summed up entirely in the last three lines in which state that medusa made that transformation herself, from beautiful life to death stone, emotionally at least and then she brings the same to others. Finally, the diction of â€Å"look† in the last line is both fitting and ironic because it is that very look that will literally turn you to stone just as she has been metaphorically turned to stone herself. Throughout the poem duffy displays medusa in a way the she has not been seen before. In many instances the man appears to be blamed for what she has become as though it I know fault of her own, though she seem perversely pleased with herself, which, from her perspective, sheds her in a positive light. Although the reader cannot shake the negative connotations that have been developed with medusa it is evident that she thinks very highly of herself, and what do the opinions of other, insignificant, people matter to one who is as self important as medusa?

Is abortion illegal Essay Example | Topics and Well Written Essays - 500 words

Is abortion illegal - Essay Example In spite of the fact of morality, a woman has the right to privacy and choice to abort her fetus. The populaces that hold a "pro-life" approach argue that a woman who has an abortion is killing a child. The "pro-choice" viewpoint holds this is not the case. A fetus is not up till now a baby. It does not have the criteria consequent from the understanding of living human beings. "Nations around the world have adopted laws that protect women's right to choose abortion."1 "Life and Liberty for Women is not afraid or ashamed to speak of and defend a woman's right to have an abortion through the second trimester of pregnancy."2 "Abortion is every woman's right"3 "The Central Issue in the abortion debate is the humanity of the fetus. No other consideration is decisive. Indeed the opponents of abortion rest their entire case on a single argument: If the fetus is a human being, then abortion is murder."4 The statement "Abortion is every woman's right" is significant to the study since Abortion is a right, and all rights are utter so cannot be "balanced" away. Therefore, a pregnant woman, like all other persons, has the right to find out her own fate and the fate of her body, to decide what comprises her own best concern and private happiness and to work for its achievement, so long as she respects the same rights in others.

Why did Communism collapse so suddenly in 1991 Explain your answer Essay

Why did Communism collapse so suddenly in 1991 Explain your answer - Essay Example Communism seeks to establish a classless society for all. It endeavors to erase all differences of class and creed and bring all the citizens at the same forefront with the government leading them all. However, the communist theory has failed miserably in the past. It is believed that the communist theory includes some connotations that are bound to fail. Capitalists mock the communist theory by saying that if there will always be the poor then there will always be the rich. There would be classification and divisions with the dos and donts, and any effort to create a society that does not have classes, this side of heaven, mainly by means of the aggressive and godless means of Communism, is bound to lead towards frustration and failure1. Before moving on to discussing why this theory failed so miserably and what was inherently wrong with the idea of having a classless state with absolute government power, one needs to know what lead to this concept. The concept of communism belongs to the Marxist school of thought. Since the late 19th century the ideas of socialism were quite popular among the working class citizens around the world and they began to show their true color when in the early 20th century several countries formed their own Communist parties. While the ruling classes reprimanded the concept of communism or socialism since it brought their power at stake, it was very much appreciated by the working class. In the interwar period, however, since different classes began to fight for or against communism, its image tarnished. It wasn’t all good and now everyone knew that. The socialist activists stepped up their campaigns against their oppressor regimes and resorted to violence to achieve their goals2 . These ruthless activities, instead of promoting communism amongst the masses, lead to previously pro-communist populace to lose their interest in the movement. Therefore the number of those who favored communism

It also operates Qantas catering that runs two businesses: Snap Fresh, a big manufacturer of frozen meats and other, different meal components; Q catering this is premium catering businesses. Q catering operates 7 centers across Australia and also sells to other airlines. It also supplies about four million bottles of the country’s wine. The airline has interests in the Singapore firm Holiday Tours and Travel. The airline merged wi th Jet set in July 2008, to create Jet set Travel World, where Qantas Airline owns 58 percent. Qantas program, frequent flyer, is another business with 15 million members. The program supplied over 450000 award seats on the program partner airlines.

In response to this financial crisis Qantas airline has grounded decided to ground 10 aircraft, and has also informed Boeing that it will defer i ts orders for the 737-14 version of the aircraft and also a delay for the delivery of the new 15, 787 Dream liners. The decisions taken by the outgoing CEO George Dixon, to save money, has affected the airline both negatively and positively. He improved the bottom line but destroyed the operations of the Qantas engineers and the baggage handlers. British airways and Qantas airline underwent a number of merger talks in the late 2008. The benefits of this merger was the economies of scale present in the buying and flying of the aircraft, joint frequent flyer scheme and also, the joint IT scheme. However, problems in negotiations proved that the merger would not proceed, and the Qantas executives claimed to be looking for mergers with other airlines. The downsizing of the airline led to a number of strikes by the airline engineers and the baggage handlers.

This number of strikes have cost the airline lost revenue as more than 300 flights had to be cancelled during the period of the standoff between the management unions and the management board. During this period, Qantas airline lost Air New Zealand, which transitioned out of its maintenance contract with the airline, and opted to use the Cathay Pacific maintenance people.

Mass Media, Culture, and Society Essay Example | Topics and Well Written Essays - 1250 words

Mass Media, Culture, and Society - Essay Example Mass media has traditionally been associated with the responsibility of imparting useful information to the wider masses. This role however has changed over the years. With the passage of time, popular culture has impacted the media. News channels are now focused on giving information, which will earn the channels and the programs higher TRP ratings as opposed to following the rules and regulations. Videos of terrorist attacks and bombings which have been aired on the national news channels are not only disturbing, but it is also against the rules of broadcasting. Similarly newspapers and tabloids print pages contain information about celebrities and their lives, where more pressing issues are often ignored (Berger, 10). A couple of decades back, even movies and TV shows had some morals in them which the producers and writers wanted to put across to the world. They were a source of entertainment but in addition to that they were also a source of beneficial lesson or information. This has changed today. Today the media is market driven. They show the masses what they want to see. The entertainment industry is taking over, to an extent that even news broadcasting has become a source of entertainment (Stevenson). Political talk shows, which have been providing a platform for politicians to discuss topics of interest on a neutral ground, have now become programs which just show how these politicians argue and insult each other. News broadcasting has turned very similar to live drama broadcasting. ... Instead of producing films which are creative and convey a certain message across to the audience, the films produced follow a certain formula that emphasizes on materialistic and superficial things. With shallow and unconvincing characters, these films are based on the basic concept of aggression and greed. The plots are simple to the point that it looks as if templates are used for film making (Berger, 111). One recent example of a news channel broadcasting visuals for higher ratings was from the incident that took place in Karachi on November 28, 2012. A man fell from an 8-storey high building and the Pakistani news channels were constantly telecasting a live video footage of the entire incident. This news piece is one of the many examples which are telecasted on the local news channels. In order to get higher ratings and stay ahead of the numerous competitors, news channels pride themselves to be the first ones to convey the latest new to the masses. However, in the process of be ing on the top and being the first ones at every incident, news channels have forgotten the basic ethics that should follow (Khan). Another example of the amalgamation of mass media and culture are the numerous talk shows, which are aired almost every night on the Pakistani news channels. These shows include Mere Mutabiq (According to Me), To the Point, Target Point and Islamabad tonight to name a few. All of these shows follow the same pattern – members of opposing parties sitting together and discussing recent issues. However, what actually takes place is not discussion, but a blame game. Each party member blames the other political party for misconduct and corruption and thus, results in an argument. Journalism ethics

Contract Law on Offer and Acceptance Case Study

Contract Law on Offer and Acceptance - Case Study Example Hence Brenda succeeds on the both the counts against Andrew. Tuesday Morning: Brenda replied by e mail that the price of 50 was a mistake instead of 500 and offered to Andrew the car at a discounted price of 450.and kept the offer open till 12.00 p.m on Friday. and Andrew replied that he would consider the new offer though expressing annoyance at Brenda's mistake. Brenda had corrected the price on the website before receipt of Andrew's offer. An offer is made when one person signifies to another his willingness to do or not to do a certain act with an intention that it shall be binding on the offeror if accepted by the person to whom the offer is made. The latter is called 'offeree"1 The offeror's signifiying act called expression of willingness may be by means of a letter, newspaper, websites, e mail and also by conduct by which an offeror may be genuinely offering or just displaying an act what is known as 'invitation to treat" As such goods advertised are only 'invitation to treat'. 2 They are of unilateral nature i.e. open to the whole world to accept such as offer for rewards etc. 3 In Partridge v Crittenden [1968], appellant Patridge had been convicted for sale of banned variety of bird punishable under Protection of Birds Act 1954 by inserting a classified advertisement in a journal without mentioning the words "offer for sale" In the appeal it was held to be an invitation to treat and not an offer for sale and co nviction was set aside. On the other hand in the case of Carlill v Carbolic Smoke Ball Co [1893], an exception was made because the offeror meant business by depositing a certain sum of money as a reward for any one contracting influenza inspite of using medicine. So they could not escape liability stating their offer was an invitation to treat. Question arises website advertisements are offers or invitations to treat, relevant the instant case of Andrew v Brenda. .An offer is a set of conditions contemplating acceptance and capable of being accepted. "Thus in Thomson v James (1855) 18 D 1, Lord President MacNeill said, 'an offer is nothing until it is communicated' (at p.10). This is because an offer is not capable of acceptance until it has been communicated to the offeree" 4 "It is important to be able to differentiate between these invitations to treat and true offers, as acceptance of an offer creates a concluded contract whereas 'acceptance' of an invitation to treat is merely an offer. To assist in the identification of such invitations the law has developed presumptions as

Pediatric Healthcare Disparities Essay Example for Free

Pediatric Healthcare Disparities Essay Disparities in healthcare of children are complex problem that is associated with the disparities that exist in healthcare systems. These inequalities in the access to health care include the following factors: race and ethnicity, insurance status, education, English language proficiency, and poverty(Sobo, 2006). The aforementioned factors affect access to healthcare and the quality of service received. The racial disparities in pediatric healthcare are a tremendously pervasive depressing problem. Instead of those who most need the healthcare receiving it, they are given less priority hence these services did not reach them(Lieu, 2003). Among the most important gauges of soundness of health in children is being able to acquire healthcare services that are of high quality. Children’s health needs appropriate and apt use of medical services like physical examinations, laboratory test for diseases, and immunizations. These services are deprived to the children of the socioeconomic minority. Healthcare disparities observed pertains to less access to healthcare services and acquisition of low quality health care services by people whom are poor, of racial and ethnic minority, limited English proficiency, and low educational attainment. Children that belong to the racial and ethnic minorities receive an inferior quality of healthcare. Not only are there a small number of children in the minority class suffering from this type of problem but millions of them(Beal, 2004). Mortality in infants in Black communities is doubled when compared to the mortalities of infants of the White communities. Even this maternal and societal health’s most significant gauge confirms that the existence of racial and ethnic disparities is true. In United States, the people of color at present have a bleak healthcare condition. Approximately 20 percent Black and 30 percent Hispanic Americans do not have consistent source of medical care compared to less than 16 percent of the White Americans. There is a three-fold increase to the numbers of Hispanic children that do not have access to healthcare when compared to children that are not Hispanic Americans(AHRQ 2000). These alarming data poses a threat to the state of health especially of children that belongs to this people that belongs to the racial and ethnic minorities. Studies which were done for the determination of the factors involved in the disparities of pediatric healthcare are of significance in identification of populations involved in these dilemma. In a study done by Hambinge et al, it was found that in well-child visits (WCVs) the black and Latino children were given less counseling(Hambidge, 2007). Racial minorities in United States such as the Latino and Black children are the main population that suffers from these inconsistencies in the provision of healthcare. Scott (2004) indicated in the conclusion of their study that Hispanic or Latino children has increased risk of having no access to healthcare services in the last 15 years. Hispanic or Latino is defined in the study as individuals that came from countries in Central America, North America, Caribbean, and Europe. The absence of access to healthcare services was found to be greater in Hispanic/ Latino children with low economic status, whose parents have no college degree, and born in other countries or not born in United States. The race which is most predispose to lack of access healthcare are children of Mexicans due to their poverty status or low educational achievements(Scott 2004). The study of Flores (2005) found an association in children’s health and healthcare to Limited English Proficiency (LEP) of their parents. This factor has a significant impact as a barrier for the acquisition of healthcare in children. The research also indicated that parental LEP has a direct association to the possibility that children in need of medical care can not be brought to healthcare providers. Racial and ethnic healthcare disparity is proven through this study because the bulk of the children that participated in the study were of racial and ethnic minority groups, 82 percent Latino, 2 percent Caribbean black, 10 percent African American, 2 percent non-Latino white, 1 percent African, 0. 3 percent Asian, and 1 percent combination of other races. Large portion of this participating population can not speak English very well. Thus, the ability to speak English fluently of children and their parents will determine their chance of receiving appropriate healthcare services(Flores, 2005). The continuing presence of racism in the healthcare sector of the society is found to be related to the underrepresentation of minority racial and ethnic groups in professions of the medical industry. Generally speaking people that are poor are predominantly people of color such as the Blacks and Hispanics. Poverty does not allow them to be with the education needed to work in healthcare industry so they are underrepresented in this profession. Study results prove that people of color in the medical profession tend to provide more healthcare services to those people which are also of color. The possibility of providing healthcare services to the poor portion of the population is also proven to be attributed to those medical professionals that are people of color. This underrepresentation explains why the racial and ethnic minority receive less healthcare services(ERASE ). Even though it is said that in professional fields the race of an individual hardly matters it is rarely true. The complexity of the factors that are involve in the disparities of healthcare in general should not hinder in the search and implementation of solutions that will alleviate the disparities suffered by the people of racial and ethnic minority, low educational attainment, limited English proficiency, and economically challenged. It is the responsibility of healthcare providers to serve the public with equality to promote the health status of the whole population instead of only those that belong to the elite portion of the population. The present ways of addressing the disparities in healthcare is focused not only on the professionals that will provide the services but also to the public consumers of these services. The goal is centered towards providing equal chance of receiving quality healthcare services. One of these strategies is the establishment of guidelines that will help medical practitioners handle, diagnose, and treat with professional competence the health cases of the people that belong to socioeconomic minority. Another strategy is helping the patients and their families pursue healthcare of high quality thru assessment of healthcare services provided by the healthcare recipient or client. Publications are written in various languages to facilitate understanding of the contents by those people that are with Limited English Proficiency. Booklets or pamphlets are also produces to help parents assess if their children were provided with health services of high quality. The Agency for Healthcare Research and Quality (AHRQ) is also finding ways to develop enhanced strategies for quality improvement of healthcare services. Their initiative is focused on eliminating healthcare racial and ethnic disparities, supporting of the healthcare providers that supply services to communities of the minority people, and conducting seminars or trainings on how to address healthcare disparities(AHRQ 2000). The existence of racism can not be denied even though the society has already learned to accept that people are of diverse cultures and beliefs. Various organizations have been established to stop the disparities in healthcare of children and promote equality in the acquisition of these services. Despite the research and strategies that are implemented to counteract the increasing numbers of children having no access to good quality healthcare especially those of the minority racial and ethnic origin, the problem is still present along its complexities. Though it’s a cliche â€Å"children are the future of every nation† thus it is only prompt that actions should be undertaken to promote holistic growth of their well being. Eradication of these disparities in pediatric healthcare will ensure that tomorrow’s generation will have a better health.

Hinduism and Buddhism Essay Example for Free

Hinduism and Buddhism Essay Hinduism and Buddhism are two of the renowned religions world widely. Hinduism is the religion of the great majority of the people of India. The word comes from the Sanskrit sindhu, â€Å"river,† and originally referred to the Indus. Hinduism is actually a collection of many native Indian religions, past and present. It is responsible for the social structure of India, especially for the caste system (a hereditary class system). Hinduism has about 20 sects, with beliefs that range from primitive forms of animism to the highest reaches of mysticism and philosophy. Many of the sects and cults seem to be separate religions. Yet all have a family relationship since they spring from common traditions and thrive. Hindus believe in rebirth, or reincarnation, and in what they call the law of karma. Under this law the conditions of each new lifetime are determined by the actions of the preceding life. To the Hindu, salvation consists of liberating the soul from attachment to worldly desires in order to gain union with Brahman. If a Hindu dies liberated he must be born again into this world and again endure its suffering (Stutley, 2004). The Vedas describe four main castes. 1. The Brahmins exercise spiritual power. (Brahmin is also spelled Brahman). 2. The Kshatriyas are warriors who exercise secular power. 3. The Vaisyas are merchants and cultivators. 4. The Sudras are artisans and laborers. Hindu worship for most part takes place in the home. A Hindu temple or shrine is considered an abode of deity and is not used for communal worship. There are kinds of Hindu clergy. Temple priests collect offerings and care for the temples and shrines. Domestic priests perform rites involving births, marriages, and deaths. Gurus are spiritual teachers. Sadhus are monks; most live in monasteries, but many live as wandering mendicants (beggars) (Chaudhuri, 1999). While Buddhism is a religion founded by Siddhartha Gautama (â€Å"Buddha,† or â€Å"The Enlightened One†) in India about 500 B. C. Buddhism is the chief religion of Burma, Sri Lanka, Thailand, Japan, Korea, Mongolia, Kampuchea, Laos, and China. It has been estimated that about one-fifth of the world’s people are Buddhists. Because many Buddhists also practice Confucianism or Taoism, however, some authorities estimate world membership to be much smaller. In the United States, there are a number of organized Buddhist congregations (Carrithers, 2003). Buddhism consists of numerous sects with varying practices and beliefs. Some of these sects are so different from the others that they appear to be separate religions. But all sects have in common the belief that they are following the principles laid down by Gautama. Early Buddhism, the religion as taught by Gautama, developed into two branches—Theravada Buddhism and Mahayana Buddhism (Mizuno, 2001). Although Buddhism was originally a reform movement that rejected certain beliefs and practices of Hinduism, the two religions have several important beliefs in common. Among them are reincarnation, the ideas that a living thing can be reborn in a new body; the law of karma, which holds that events in life are effects whose cause lies in previous lives and acts; and liberation, or salvation, the state of being free of the law of karma and rebirth (Conze, 2002). According to Buddhism, liberation is attained through understanding and practice of the Four Noble Truths: 1. There is suffering in life. 2. Suffering is caused by desire for pleasure, existence, and prosperity. 3. Suffering and rebirth cease when one ceases such desires, leading to enlightenment, or Nirvana, a blessed state in which peace, harmony, and joy are attained. The Eightfold Path is also called the Middle Way—because of its emphasis on avoiding such extremes as following sensuous pleasures on the one hand, and self-punishment on the other. The Buddhists must at all times observe in the high moral principles described in the Eightfold path, which emphasizes nonviolence and the brotherhood of all. Reference: 1. Carrithers, Michael.

Study On Adaptive Delta Modulation And Demodulation Computer Science Essay

Study On Adaptive Delta Modulation And Demodulation Computer Science Essay A modem to improve communication system performance that uses multiple modulation scheme comprising modulation technique and encoder combinations. As communication system performance and objective change, different modulation schemes may be selected. Modulation schemes may also be selected upon the communication channel scattering function estimate and the modem estimates the channel scattering function from measurements of the channels frequency (Doppler) and time (multipath) spreading characteristics. An Adaptive sigma delta modulation and demodulation technique, wherein a quantizer step size is adapted based on estimates of an input signal to the quantizer, rather than on estimates of an input signal to the modulator. A technique for digital conferencing of voice signals in systems using adaptive delta modulation (ADM) with an idle pattern of alternating 1s and 0s has been described. Based on majority logic, it permits distortion-free reception of voice of a single active subscriber by all the other subscribers in the conference. Distortion exists when more than one subscriber is active and the extent of this distortion depends upon the type of ADM algorithm that has been used. An LSI oriented system based on time sharing of a common circuit by a number of channels has been implemented and tested. This technique, with only minor changes in circuitry, handles ADM channels that have idle patterns different from alternating single 1s and 0s. This method used for noise reduction. The modulator factor does not require a large amount of data to be represented. Representation is based upon a frequency domain function having particular characteristics. A preferred embodiment of the invention incorporates transform or sub band filtered signals which are transmitted as a modulated analog representation of a local region of a video signal. The modulation factor reflects the particular characteristic. Side information specifies the modulation factor 1.2. Aim: Digital techniques to wirelessly communicate voice information. Wireless environments are inherently noisy, so the voice coding scheme chosen for such an application must be robust in the presence of bit errors. Pulse Coded Modulation (PCM) and its derivatives are commonly used in wireless consumer products for their compromise between voice quality and implementation cost. Adaptive Delta Modulation (ADM) is another voice coding scheme, a mature technique that should be considered for these applications because of its bit error robustness and its low implementation cost. 1.3. Objective: To show the Adaptive Delta Modulation (ADM) voice coding scheme which is the best coding scheme procedure when compare to all other techniques. The main part of the procedure is illustrated. 1.4. Methodology: Getting knowledge over different modulation and demodulation techniques Understanding Delta modulation and Adaptive delta modulation. Studying Matlab-Simulink which is used for designing of circuit. Implementing the circuit in the lab. Tuning and fixing and calculating its efficiency CHAPTER I Delta Modulation: Delta modulation is also abbreviated as DM or Ά-modulation. It is a technique of conversion from an analog-to-digital and digital-to-analog signal. If we want to transmit the voice we use this technique. In this technique we do not give that much of importance to the quality of the voice. DM is nothing but the simplest form of differential pulse-code modulation (DPCM). But there is some difference between these two techniques. In DPCM technique the successive samples are encoded into streams of n-bit data. But in delta modulation, the transmitted data is reduced to a 1-bit data stream. Main features: * The analog signal is similar as a series of segments. * To find the increase or decrease in relative amplitude, we should compare each and every segment of the approximated signal with the original analog wave. * By this comparison of original and approximated analog waves we can determine the successive bits for establishing. * only the change of information is sent, that is, only an increase or decrease of the signal amplitude from the previous sample is sent whereas a no-change condition causes the modulated signal to remain at the same 0 or 1 state of the previous sample. By using oversampling techniques in delta modulation we can get large high signal-to-noise ratio. That means the analog signal is sampled at multiple higher than the Nyquist rate. Principle In delta modulation, it quantizes the difference between the current and the previous step rather than the absolute value quantization of the input analog waveform, which is shown in fig 1. Fig. 1 Block diagram of a Ά-modulator/demodulator The quantizer of the delta modulator converts the difference between the input signal and the average of the previous steps. The quantizer is measured by a comparator with reference to 0 (in 2- level quantizer), and its output is either 1 or 0. 1 means input signal is positive and 0 means negative. It is also called as a bit-quantizer because it quantizes only one bit at a time. The output of the demodulator rises or falls because it is nothing but an Integrator circuit. If 1 received means the output raises and if 0 received means output falls. The integrator internally has a low-pass filter it self. Transfer Characteristics A signum function is followed by the delta modulator for the transfer characteristics. It quantizes only levels of two number and also for at a time only one-bit. Output signal power In delta modulation amplitude it is does not matter that there is no objection on the amplitude of the signal waveform, due to there is any fixed number of levels. In addition to, there is no limitation on the slope of the signal waveform in delta modulation. We can observe whether a slope is overload if so it can be avoided. However, in transmitted signal there is no limit to change. The signal waveform changes gradually. Bit-rate The interference is due to possibility of in either DM or PCM is due to limited bandwidth in communication channel. Because of the above reason DM and PCM operates at same bit-rate. Adaptive Delta Modulation (ADM) Another type of DM is Adaptive Delta Modulation (ADM). In which the step-size isnt fixed. The step-size becomes progressively larger when slope overload occurs. When quantization error is increasing with expensive the slope error is also reduced by ADM. By using a low pass filter this should be reduced. The basic delta modulator was studied in the experiment entitled Delta modulation. It is implemented by the arrangement shown in block diagram form in Figure Figure: Basic Delta Modulation A large step size was required when sampling those parts of the input waveform of steep slope. But a large step size worsened the granularity of the sampled signal when the waveform being sampled was changing slowly. A small step size is preferred in regions where the message has a small slope. This suggests the need for a controllable step size the control being sensitive to the slope of the sampled signal. This can be implemented by an arrangement such as is illustrated in Figure Fig: An Adaptive Delta Modulator The gain of the amplifier is adjusted in response to a control voltage from the SAMPLER, which signals the onset of slope overload. The step size is proportional to the amplifier gain. This was observed in an earlier experiment. Slope overload is indicated by a succession of output pulses of the same sign. The TIMS SAMPLER monitors the delta modulated signal, and signals when there is no change of polarity over 3 or more successive samples. The actual ADAPTIVE CONTROL signal is +2 volt under normal conditions, and rises to +4 volt when slope overload is detected. The gain of the amplifier, and hence the step size, is made proportional to this Control voltage. Provided the slope overload was only moderate the approximation will catch up with the wave being sampled. The gain will then return to normal until the sampler again falls behind. Comparison of PCM and DM When coming to comparison of Signal-to-noise ratio DM has larger value than signal-to-noise ratio of PCM. Also for an ADM signal-to-noise ratio when compared to Signal-to-noise ratio of companded PCM. Complex coders and decoders are required for powerful PCM. If to increase the resolution we require a large number of bits per sample. There are no memories in Standard PCM systems each sample value is separately encoded into a series of binary digits. An alternative, which overcomes some limitations of PCM, is to use past information in the encoding process. Delta modulation is the one way of doing to perform source coding. The signal is first quantized into discrete levels. For quantization process the step size between adjacent samples should be kept constant. From one level to an adjacent one the signal makes a transition of transmission. After the quantization operation is done, sending a zero for a negative transition and a one for a positive transition the signal transmission is achieved. We can observe from this point that the quantized signal must change at each sampling point. The transmitted bit train would be 111100010111110 for the above case. The demodulator for a delta-modulated signal is nothing but a staircase generator. To increments the staircase in positively a one should be received. For negative increments a zero should be receive. This is done by a low pass filter in general. The main thing for the delta modulation is to make the right choice of step size and sampling period. A term overloading is occurred when a signal changes randomly fast for the steps to follow. The step size and the sampling period are the important parameters. In modern consumer electronics short-range digital voice transmission is used. There are many products which uses digital techniques. Such as cordless telephones, wireless headsets (for mobile and landline telephones), baby monitors are few of the items. This digital techniques used Wirelessly communicate voice information. Due to inherent noise in wireless environments the Voice coding scheme chosen. For such an application the presence of robust bit errors must be. In the presence of bit errors Pulse Coded Modulation (PCM) and its derivatives are commonly used in wireless consumer products. This is due to their compromise between voice quality and implementation cost, but these are not robust schemes. Another important voice coding scheme is Adaptive Delta Modulation (ADM). It is a mature technique for consideration for these types of applications due to its robustness in bit error and its low implementation cost. To quantize the difference between the current sample and the predicted value of the next Sample ADM is used. It uses a variable called step height which is used to adjustment of the prediction value of the next sample. For the reproduction of both slowly and rapidly changing input signals faithfully. In ADM, the representation of each sample is one bit (i.e. 1 or 0). It does not require any data framing for one-bit-per-sample stream to minimizing the workload on the host microcontroller. In any digital wireless application there should be Bit errors. In ideal environment most of the voice coding techniques are provided which are good in quality of audio signals. The main thing is to provide good audio signals in everyday environment, there may be a presence of bit errors. For different voice coding methods and input signals the traditional performance metrics (e.g. SNR) does not measure accurately in audio quality. . Mean Opinion Score (MOS) testing is the main important parameter which overcomes the limitations of other metrics by successfully in audio quality. For audio quality the MOS testing is used. It is a scale of 1 to 5 which tells the audio quality status. In there 1 represents very less (bad) speech quality and 5 represents excellent speech quality. A toll quality speech has a MOS score of 4 or higher than it. The audio quality of a traditional telephone call has same MOS value as above. The below graphs shows the relationship between MOS scores and bit errors for three of the most common voice coding schemes. Those are CVSD, ÃŽÂ ¼-law PCM, and ADPCM. A continuously Variable Slope Delta (CVSD) coding is a member of the ADM family in voice coding schemes. The below graph shows the resulted audio quality (i.e. MOS score). All three schemes explain the number of bit errors. As the no of bit errors increases the graph indicates that ADM (CVSD) sounds better than the other schemes which are also increase. In an ADM design error detection and correction typically are not used because ADM provides poor performance in the presence of bit errors. This leads to reduction in host processor workload (allowing a low-cost processor to be used). The superior noise immunity significantly reduced for wireless applications in voice coding method. The ADM is supported strongly by workload for the host processor. The following example shows the benefits of ADM for wireless applications and is demonstrated. For a complete wireless voice product this low-power design is used which includes all of the building blocks, small form-factor, including the necessary items. ADM voice codec Microcontroller RF transceiver Power supply including rechargeable battery Microphone, speaker, amplifiers, etc. Schematics, board layout files, and microcontroller code written in C. Delta modulation (DM) may be viewed as a simplified form of DPCM in which a two level (1-bit) quantizer is used in conjunction with a fixed first-order predictor. The block diagram of a DM encoder-decoder is shown below.   The dm_demo shows the use of Delta Modulation to approximate an input sine wave signal and a speech signal that were sampled at 2 KHz and 44 KHz, respectively. The source code file of the MATLAB code and the out put can be viewed using MATLAB. Notice that the approximated value follows the input value much closer when the sampling rate is higher. You may test this by changing sampling frequency, fs, value for sine wave in dm_demo file. Since DM (Delta Modulator) approximate a waveform Sa (t) by a linear staircase function, the waveform Sa (t) must change slowly relative to the sampling rate. This requirement implies that waveform Sa (t) must be oversampled, i.e., at least five times the Nyquist rate. Oversampling means that the signal is sampled faster than is necessary. In the case of Delta Modulation this means that the sampling rate will be much higher than the minimum rate of twice the bandwidth. Delta Modulation requires oversampling in order to obtain an accurate prediction of the next input. Since each encoded sample contains a relatively small amount of information Delta Modulation systems require higher sampling rates than PCM systems. At any given sampling rate, two types of distortion, as shown below limit the performance of the DM encoder.   Slope overload distortion: This type of distortion is due to the use of a step size delta that is too small to follow portions of the waveform that have a steep slope. It can be reduced by increasing the step size. Granular noise: This results from using a step size that is too large too large in parts of the waveform having a small slope. Granular noise can be reduced by decreasing the step size. Even for an optimized step size, the performance of the DM encoder may still be less satisfactory. An alternative solution is to employ a variable step size that adapts itself to the short-term characteristics of the source signal. That is the step size is increased when the waveform has a step slope and decreased when the waveform has a relatively small slope. This strategy is called adaptive DM (ADM). Block Diagram Adaptive Delta Modulation for Audio Signals: While transmitting speech for e.g. telephony the transfer rate should be kept as small as possible to save bandwidth because of economic reason. For this purpose Delta Modulation, adaptive Delta modulation, Differential Pulse-Code modulation is used to compress the data. In this different kind of Delta modulations and Differential Pulse Code modulations (DPCM) were realized to compress audio data. At first the principal of compressing audio data are explained, which the modulations based on. Mathematical equations (e.g. Auto Correlation) and algorithm (LD recursion) are used to develop solutions. Based on the mathematics and principals Simulink models were implemented for the Delta modulation, Adaptive Delta modulation as well as for the adaptive Differential Pulse Code modulation. The theories were verified by applying measured signals on these models. CHAPTER II Pulse-code modulation: Pulse-code modulation (PCM) is a method used to digitally represent sampled analog signals, which was invented by Alec Reeves in 1937. It is the standard form for digital audio in computers and various Compact Disc and DVD formats, as well as other uses such as digital telephone systems. A PCM stream is a digital representation of an analog signal, in which the magnitude of the analogue signal is sampled regularly at uniform intervals, with each sample being quantized to the nearest value within a range of digital steps. PCM streams have two basic properties that determine their fidelity to the original analog signal: the sampling rate, which is the number of times per second that samples are taken; and the bit-depth, which determines the number of possible digital values that each sample can take. Digitization as part of the PCM process In conventional PCM, the analog signal may be processed (e.g. by amplitude compression) before being digitized. Once the signal is digitized, the PCM signal is usually subjected to further processing (e.g. digital data compression). PCM with linear quantization is known as Linear PCM (LPCM). Some forms of PCM combine signal processing with coding. Older versions of these systems applied the processing in the analog domain as part of the A/D process; newer implementations do so in the digital domain. These simple techniques have been largely rendered obsolete by modern transform-based audio compression techniques. * DPCM encodes the PCM values as differences between the current and the predicted value. An algorithm predicts the next sample based on the previous samples, and the encoder stores only the difference between this prediction and the actual value. If the prediction is reasonable, fewer bits can be used to represent the same information. For audio, this type of encoding reduces the number of bits required per sample by about 25% compared to PCM. * Adaptive DPCM (ADPCM) is a variant of DPCM that varies the size of the quantization step, to allow further reduction of the required bandwidth for a given signal-to-noise ratio. * Delta modulation is a form of DPCM which uses one bit per sample. In telephony, a standard audio signal for a single phone call is encoded as 8000 analog samples per second, of 8 bits each, giving a 64 Kbit/s digital signal known as DS0. The default signal compression encoding on a DS0 is either ÃŽÂ ¼-law (mu-law) PCM (North America and Japan) or A-law PCM (Europe and most of the rest of the world). These are logarithmic compression systems where a 12 or 13-bit linear PCM sample number is mapped into an 8-bit value. This system is described by international standard G.711. An alternative proposal for a floating point representation, with 5-bit mantissa and 3-bit radix, was abandoned. Where circuit costs are high and loss of voice quality is acceptable, it sometimes makes sense to compress the voice signal even further. An ADPCM algorithm is used to map a series of 8-bit  µ-law or A-law PCM samples into a series of 4-bit ADPCM samples. In this way, the capacity of the line is doubled. The technique is detailed in the G.726 standard. Later it was found that even further compression was possible and additional standards were published. Pulse code modulation (PCM) data are transmitted as a serial bit stream of binary-coded time-division multiplexed words. When PCM is transmitted, premodulation filtering shall be used to confine the radiated RF spectrum. These standards define pulse train structure and system design characteristics for the implementation of PCM telemetry formats. Class Distinctions and Bit-Oriented Characteristics The PCM formats are divided into two classes for reference. Serial bit stream characteristics are described below prior to frame and word oriented definitions. Two classes of PCM formats are covered in this chapter: the basic, simpler types are class I, and the more complex applications are class II. The use of any class II technique requires concurrence of the range involved. All formats with characteristics described in these standards are class I except those identified as class II. The following are examples of class II characteristics: a. Bit rates greater than 10 megabits per second b. Word length in excess of 32 bits. c. fragmented words d. more than 8192 bits or 1024 words per minor frame. e. uneven spacing, not within the definition of sub commutation or super commutation f. Format changes. g. asynchronous embedded formats h. tagged data formats. i. packet telemetry j. formats with data content other than unsigned straight binary, discrete, or complement arithmetic representation for negative numbers such as floating point variables, binary-coded decimal, and gain-and-value k. asynchronous data transmission l. merger of multiple format types Demodulation: Demodulation is the act of extracting the original information-bearing signal from a modulated carrier wave. A demodulator is an electronic circuit used to recover the information content from the modulated carrier wave. These terms are traditionally used in connection with radio receivers, but many other systems use many kinds of demodulators. Another common one is in a modem, which is a contraction of the terms modulator/demodulator. Techniques: There are several ways of demodulation depending on how parameters of the base-band signal are transmitted in the carrier signal, such as amplitude, frequency or phase. For example, for a signal modulated with a linear modulation, like AM (Amplitude Modulated), we can use a synchronous detector. On the other hand, for a signal modulated with an angular modulation, we must use an FM (Frequency Modulation) demodulator or a PM (Phase Modulation) demodulator. Different kinds of circuits perform these functions. Many techniques-such as carrier recovery, clock recovery, bit slip, frame synchronization, rake receiver, pulse compression, Received Signal Strength Indication, error detection and correction, etc. are only performed by demodulators, although any specific demodulator may perform only some or none of these techniques. Some Attributes of Demodulated data One important attribute of demodulation (or demod) data is that it focuses on high frequency vibration. Using a high pass filter, low frequency data is filtered out and a data collector is able to zoom in on low level high frequency vibration. This means that some peaks that would otherwise be lost in the noise floor of a normal narrow band spectrum (much lower than the normal vibration a machine emits) can be detected using demodulation techniques. Another feature of demod, or of high frequency vibration in general, is that it is easily attenuated and does not travel well through a machines structure (termed the disco effect). As one moves away from a loud music source, one tends to hear only the bass, or low frequency sound, since the treble or high frequency sounds dissipate rather quickly. This implies that vibration detected with demod is usually produced locally. In the case of a motor driving a pump through a coupling, demod data collected on the pump end will usually reflect the vibration emitted by the pump end. Lower frequency vibration may be transmitted through the coupling and may even be amplified on the other end of the machine depending upon its mobility. CHAPTER III Results: Critical Analysis: CHAPTER IV Conclusion: Short-range wireless digital voice transmission is used extensively in contemporary consumer electronics. Products such as cordless telephones, wireless headsets (for mobile and landline telephones) and baby monitors are just a few of the items that use digital techniques to wirelessly communicate voice information. Wireless environments are inherently noisy, so the voice coding scheme chosen for such an application must be robust in the presence of bit errors. Pulse coded modulation (PCM) and its derivatives are commonly used in wireless consumer products for their compromise between voice quality and implementation cost, but these schemes are not particularly robust in the presence of bit errors. Adaptive delta modulation (ADM) is a mature technique that should be considered for these applications because of its bit error robustness and its low implementation cost. ADM is a voice coding technique that quantizes the difference between the current sample and the predicted value of the next sample. It uses a variable step height to adjust the predicted value of the next sample so that both slowly and rapidly changing input signals can be faithfully reproduced. One bit is used to represent each sample in ADM. The one-bit-per-sample ADM data stream requires no data framing, thereby minimizing the workload on the host microcontroller. CHAPTER V

The Media and Mad Cow Disease :: Argumentative Persuasive Topics

The Media and Mad Cow Disease Mad cow disease or Bovine Spongiform Encephalopathy is a disease that was commonly found in sheep until it recently crossed the species barrier into cows, where it began to infect people. At least that's what the media told us. Scientists like Joe Gibbs of the National Institute of Neurology in Bethesda, MD-on the other hand-are saying meat itself only carries a "minimal" risk of infection, and milk and dairy products are safe. Now for a little history on Mad Cow Disease: It was a disease prevalent in sheep for hundreds of years (Scrapie) and then it crossed the species border and appeared in cattle in Britain about 15 years ago where it is known as Bovine Spongiform Encephalopathy or BSE. Mad Cow Disease is just a nickname-the cows do not actually go mad. The British government just recently decided that it has crossed another species barrier and appeared in humans as a disease known as Creutzfeld-Jakob Disease or CJD. CJD is a fatal, degenerative brain disease which takes from 2 to 30 years to incubate. There is currently no cure and in 90% of cases the infected person will die within a year. In the past year ten British people have contracted a variant of CJD apparently related to BSE; eight have already died. The World Health Organization (WHO) produced a fact sheet on the risk of BSE in humans on March 26, 1996. Their main conclusion is that "if the measures taken in the United Kingdom...were being strictly implemented, the risk of...possible BSE transmission to humans, would be minimized." The media has something else to say about this issue. Warnings throughout local news broadcasts and newspapers were saying that Mad Cow Disease was a serious threat. One article I found on the Internet called Mad Cow Disease "much more serious than AIDS." The heavily footnoted article finished with the challenge: "Do not take my word for any of this. Go to the library; check out Agricola, Medline, Biosis, Cab Extracts, the on-line catalog, anything. Time is of the essence." The web site that published it was an independent student-run magazine from Cornell University in Ithaca, NY. It had been published in 1994, well before the crisis in Britain. It was written by Michael Greger who had been a junior at Cornell when he wrote it and is now a medical student at Tufts University School of Medicine.

Syed Mokhtar Al Bukhary

He was born at Kampung Hutan Keriang in Alor Setar, Kedah in 1951. It was nine years later that his mother, Sharifah Rokiah, packed him off to stay with his British soldier uncle in Johor Bahru. He returned to Alor Setar in 1966, continued his Form Three studies at St Michael’s Secondary School, and helping out with his father’s cattle trading business. He dropped out of school before completing Form Five, ventured into meat trading after his father called it a day when the cattle business was badly affected by the foot and mouth disease.From there, he went into rice trading, the transportation business, garment contract manufacturing (for JCPenny and Kmart), property development and a host of other businesses. And he did not wait to become a rich man to share his wealth with the unfortunate. He started giving when he was still struggling as a rice trader. His mother had urged him to contribute to the poor, regardless of race or religion.

He has also been sponsoring some 50 pilgrims to perform their Haj every year since 1990s. Charity is his all-consuming passion. It has been the cornerstone of his business world from the start. â€Å"Wealth has to circulate. When you make money, you have to give it away. â€Å"My mother taught us nothing is yours until you have given it away with all your heart in the hope it will make someone’s life easier.†As far as Syed Mokhtar is concerned, he is merely the steward of wealth that is meant to be spent in the service of mankind. In 2007, the May 20 edition of the World Business nominated Syed Mokhtar as one of the Top 20 â€Å"Progressive Asians†, citing him as one â€Å"who has no interest in personal aggrandisement. † In 2008, Malaysia honoured him as Tokoh Ma’al H ijrah 1429H or Man of the year 2008 in recognition of his contributions to the country.

Today I would like to tell you an episode of Tan Sri Syed Mokhtar Al Bukhary's life. Hope you will enjoy it! It was the most frightening 70 minutes for Syed Mokhtar when he met Dr Mahathir, who was a Malaysian Prime Minister at that time. The meeting held on January 16, 1997 which has lasted for 70 minutes has become a very unforgettable memory in his life. When he meet Dr Mahathir , Syed Mokhtar has been treated unfriendly.Dr Mahathir did not smile when he greeted him. Syed Mokhtar felt very nervous when he sees the serious face of Dr Mahathir. Dr Mahathir did not even ask him to seat. So he decided to sit and present all the documents he had prepared on its business at Kedah even without being asked. After 70 minutes passed Dr Mahath ir still did not speak even a word. Syed Mokhtar decided to leave all of his documents and walk out of Dr. Mahathir’s room. This incidence has become the most terrifying 70 minutes for Syed Mokhtar and will be remembered forever.However, the fear was eventually paid off because he has successfully implemented projects that he presented to Dr Mahathir.

Factors that contributed to the rise and development of sociology Essay

This essay serves to outline the factors that contributed to the rise of sociology and the latter`s development. In simply terms, sociology is the scientific study of the society and human behavior. The emergence of sociology traces back to the eighteenth century up to present day. Johnson (1998) suggests that in summary, the rise and development of sociology is based on political, economic, demographic, social and scientific changes. Ritzer (2008) asserts that the immediate cause for the beginning of sociology were political unrests especially the French Revolution that took over from the eighteenth century to the nineteenth century. The turmoil of the French Revolution spread throughout Europe and other nations. Kornblum (2008) suggests that the political upheavals were associated with tremendous social changes. The political revolutions demolished the old social order and monarchies. There was social chaos and disorder in societies that were resulted in by the political revolutions especially in the French society. Social theorists were attracted by these societal changes that had been a result of the political unrests hence giving rise to the discipline of sociology. Auguste Comte (1798-1857) who is credited for being the founding father of sociology was attracted by the social changes that had arose in reaction to the political revolutions. The French philosopher Comte attributed his focus of study to the French society so as to restore social order. This marked the beginning of sociology. Therefore, it is wise to claim that the European political upheavals resulted in social changes which attracted a number of social theorists such as Comte thereby leading to the rise of the scientific study of society. Industrial Revolutions also contributed to the rise of sociology as a discipline and had great impact to the rise of sociology (Schaefer, 2010). Industrial Revolution was a period of transformation whereby economic modes of production changed from feudalism to capitalism. The industrial transformations gave in the establishment of factories and industries resulting in the creation of employment and social changes such as urbanization in the urban settlements. According to Kornblum (2008) ,individuals flocked from rural to urban settlements for employment that had been brought by the capitalist system. This resulted in over population, poor sanitation, poor health and high death rates due to poor working conditions in the urban settlements where industrialization had emerged upon. The lower classes that served as laborers for the capitalists were oppressed and exploited by the capitalists in the sense that both adults and children worked for long hours and were given low wages. Classical sociologists such as Karl Marx (1818-1883) were attracted to the study of society due to the unfair system of the capitalist economy that had been brought by the industrial revolution in Europe. Marx condemned the industrial societies and gave alternative models of society such as socialist and communist societies. As a result, it is wise to assert that societal changes brought by the industrial revolutions in Europe were one of the basic foundations of sociology. The industrial revolutions also had an impact in the beginning of American sociology. Johnson (1998) suggests that industrialization resulted in the beginning of sociology in the United States of America. Masses migrated from Europe to the United States of America due to the industrialization that had arisen in the United States of America. Individuals came to the United States of America in search of employment opportunities. The urban settlements of America were overpopulated thereby causing America social theorists to begin the scientific study of the society. American sociologists began studying social changes that had been resulted by the industrial revolution such as racism, theft and interaction among societal individuals. Charles Horton Cooley is one of the American sociologists who began the study of the society due to social changes brought by industrialization. Industrialization in the United States of America contributed to the rise of sociology in the United States of America. The scientific study of the society rose also due to the growth of science in Europe (Ritzer, 2008). Sociology emerged during a period of time when natural sciences had great honor and prestige in the European society. Natural scientists were given respect and honor in the society because they were believed to be problem-solvers in the world through the use of natural sciences such as chemistry. The growth and superiority of the natural sciences stimulated social scientists also to develop a social science that would solve societal problems that had been brought by the industrial and political revolutions. The social scientists eagerness of creating a science of society resulted the beginning of sociology which is the scientific study of the society. Auguste Comte was influenced by the growth and prestige of the natural sciences because Comte coined the term sociology which relates to the scientific study of the society. Comte alson developed positivism which was based on the notion that natural scientific methodology of objective observation and experiments should also be applied when studying the society. In this regard, the growth and prestigious position of the natural sciences resulted in the emergence of sociology. Ritzer (2008) also suggests that the enlightenment era also led to the rise of sociology. Ritzer (2008) adds that the enlightenment era was a period of rema rkable intellectual development and change. The beginning of sociology was determined by enlightenment philosophers such as Charles Montenesqueu (1689-1755) and Jean Jacques Rousseau (1712-1718). The enlightenment thinkers denounced the existing status quo stating that humans should control the universe and destroy traditional beliefs. A few sociologists were inspired by the enlightenment thinkers such as Karl Marl who favored change as suggested by the enlightenment philosophers. However, most sociologists such as Emile Durkheim and Auguste Comte followed footsteps of De-Bonald and De-Maistre rejecting enlightenment views because they were conservative, they feared change. Consequently, sociology rose as response or reaction to enlightenment philosophers. According to Ritzer (2008), the rise of socialism contributed to the rise of sociology as a discipline. Socialism was based on the notion that property should be communally owned in a society. This gave the rise of sociology because a few sociologists used doctrines of socialism in studying the society and they believed that a socialist society would mark the end of social problems. Karl Marx was inspired by socialism in developing his sociological theories because he advocated change from the capitalist to the communist society model. However, socialism also developed sociological theory because most of the sociologists particularly functionalists were conservative and criticized the socialist doctrines. Thus sociology developed due to socialism because sociology hardly consisted solely the scientific study of the society but it also comprised criticisms of some theories specifically socialism. As a result, socialism contributed to the rise and development of sociology as highlighted above. The rise of feminism had an impact in sociology because feminist ideas developed sociological theory (Ritzer, 2008).Feminism is based on the idea that women are superior as well and are equal to men in the society. Feminism rose during the liberation era of modern Western History. Feminist sociologists include Harriet Martineau (1802-1876) who wrote a textbook entitled ‘Society in America’. Male sociologists such as Comte responded conservatively to the feminist ideas. Thus feminism developed sociology because sociology had been a male dominated discipline so feminism developed sociology by transforming the discipline from a male dominated to a balanced discipline of both males and females. According to Ritzer (2008), religion also led to the rise of sociology. Ritzer (2008) citing Hinkle and Hinkle (1905) says that many early sociologists came from different religious backgrounds and were actively involved. They brought to sociology the same religious objectives they had in their personal lives. For instance, Durkheim, Karl Marx and Max Weber wrote on religion in their personal perspectives. Therefore, religion also contributed to the rise of sociology. Johnson (1998) adds on that sociology started as an academic discipline in the United States of America. Sociology started as an academic discipline at Chicago School of thought, faculties and departments of sociology were set up at Chicago and sociology emerged as an academic disciple in the Western nations between the 1920s and 1970s. This attitude has spread all over the world even into African universities. It has been seen in the essay how multiple factors influence the rise and development of sociology as a discipline in the global environment. Be it as it may, the industrial revolutions had a greater impact than any other factors outlined in essay in contributing to the rise of sociology as a discipline. Since industrial revolutions had a greater impact in contributing to the rise and development of sociology, one cannot assume that the industrial revolutions can solely explain completely the origins and development of sociology. The factor of industrial revolutions can fully explain the rise and development of sociology with other factors outlined in essay. . REFERENCES Farganis, (2011).

Macbeth as a tragic hero

The focal point of the paper is to trace the instances of Macbeth’s character as a tragic hero. This would also include the appearance of the witches when he was pure and loyal and gradually descend to the point of near insanity when he found himself nearing the ultimate stage of becoming evil himself. It could well be mentioned in this context that concept of a hero and a tragic hero is rather a perspective of the reader. However, it can be stated that a character is defined as a hero when he appears to be a central character of the story. This same person is labeled as a tragic hero if the readers find him indulging in acts that are not moral or legal. Macbeth fits this criterion of a tragic hero perfectly. (Tyerman, 233-35) The text reveals in the opening phase of the drama that Macbeth is an extremely capable warrior in accordance to the account of the captain, thus making him an important aspect of the drama. It is here through the captain’s point we come to know that Macbeth is one of the most loyal subjects of King Duncan. Next we see that Macbeth is interacting with three witches who helps us understand the three major attributes of Macbeth i.e. self-doubt, ambition and physical bravery. At the same time it beyond doubt in the basement Macbeth’s character is clean and as a solder he is true to his job and his king. (Powell, 49-50) However, at the end of this scene we see the ignition of evil in the form of ambition but in an understated phase. This was a state where he was fighting for his king and now when victory was achieved he wanted the better part of it for himself. Things started changing at a faster phase and Macbeth found himself submerging into the various aspects of evil. First he, with the instigation of Lady Macbeth, he killed King Duncan then it was the turn of Banquo. Banquo was a friend but he was eliminated in the process of keeping Macbeth’s throne safe. He did not stop to this and eliminated the family too. By the end of the play, at his death, Macbeth was completely a tragic hero as a character. (Powell, 51-53) The transition of Macbeth from being a heroic character to a tragic hero came in various phases and aspects of circumstances and political developments. It was not a justification from Macbeth’s point in the act of killing King Duncan. The only justification of Macbeth was his ambition. He was not pleased with his possession of Glamis and Cawdor, he wanted more. He wanted to be the king himself. It is true that he was instigated by the witches. The witches stated â€Å"All hail, Macbeth! Hail to thee. Thane of Glamis! / All hail, Macbeth! Hail to thee. Thane of Cawdor! / All hail, Macbeth! That shalt be king thereafter!† (Shakespeare, I.3) This lead to the assassination of Duncan with ample moral and physical support from Lady Macbeth and all this time Macbeth tries to be brave and just to himself but deep inside his morality is broken although Lady Macbeth tried her heart out to justify each evil acts of Macbeth. Macbeth knows that he is on the wrong side. For Macbeth, as he mentions time and again, Duncan is more than a king to Macbeth and is like a father to him. Thus with this act of treachery and treason he was, at a sphere, murder his father. This was a huge leap towards becoming a tragic hero as well as a negative character. (Tyerman, 235-37) Banquo too fought beside him with almost equal success and that created doubts in Macbeth’s mind as Banquo was about to become an important foe in the line of his ambition. This too was prophesied by the witches stating that the decedents of Banquo would reign as ruler. Thus it became more obvious that Banquo should be killed. However, he himself knows very well that whatever he is doing is unethical and unjustified and he becomes more aligned with the witches where the inner self represented as the witches are depicted as ridiculous and bizarre and obviously unholy with their actions like â€Å"Double, double, toil and trouble, / Fire burn and cauldron bubble† (Shakespeare, IV.i.10–11) and â€Å"eye of newt and toe of frog†. (Shakespeare, IV.i.14). At this part Macbeth becomes an extension of evil spirit such as the witches themselves. At this point whatever Macbeth acts or represents becomes a manifestation of ill fate and unholy intensions. He orders assassinations and tries to kills any and every heir to the throne like a true negative character and this plays an impact over his mind. One major part of this follow through was Macbeth’s misapprehension of blood. (Prawer, 224-5) He saw blood everywhere and it appeared to him that this blood was of Duncan’s and that it could not be rinsed away. â€Å"I am in blood / Stepped in so far, that, should I wade no more, / Returning were as tedious as go o’er† (Shakespeare, III. 4. 135–137). It would be relevant to mention that the playwright William Shakespeare depicted the character of Macbeth as a metaphor of human ambition gone wrong. This makes a character that starts as a brave and powerful warrior who is completely loyal to his abilities and more so to his king. He is well loved by his men and friends and the King himself and there is no reason to accept him as a positive hero but gradually we find him rolling into the abyss of evil procedures and ultimately becomes a tragic hero as a character. The arrival of the three witches also signifies the contributing factor as an instrument. This part of the text appears to us as a superficial metaphor but this is apparently no illusion as per the drama. This is because there was another person who witnessed the witches and he is Banquo. Therefore, it could be ascertained that the characters of the three witches are in reality not illusions but a simple dramatic manifestation of the underlying sense of ambition of a courageous warrior who has tasted success few moments ago for his King, Duncan. This was a state where he was fighting for his king and now when victory was achieved he wanted the better part of it for himself. It is but human to ask more and it is human to be prone towards errors. But these are not qualities of a hero. Thus Macbeth is more tragic hero than a hero. (Prawer, 221-2) In this context it would be relevant to mention that the trace the instances of Macbeth’s `visions’ also contributes to the fact that Macbeth was becoming a tragic hero as a character. His visions were so powerful because his desires were authoritative, commanding and extremely influential. Macbeth’s visions in the end appears to be born out of the conflict of morality and ambition and thus could be well be narrated as a manifestation of the argument of the inner self. These visions are therefore both illusions and imprint of the psychological analysis at the same time. But the overall aspect of these illusions is negative as they are all inclined towards evil visions of death, blood and fear. A character that experiences these visions makes the character negative with a malevolence vibe. Such a person is never a hero. But as he is the central character of the drama it would be logical to address him as a tragic hero. (Prawer, 223-4) In the later stages we see that illusions in the true sense of a psychologist appear in the scene with Macbeth visualizing the appearance of Banquo’s ghost. This is nothing superficial but the inner fear of an otherwise physically brave individual. Macbeth tries to be brave and just to himself but deep inside his morality is broken although Lady Macbeth tried her heart out to justify each evil acts of Macbeth. Macbeth knows that he is on the wrong side and the fear of remaining in the wrong side ultimately was manifested as the ghost of Banquo. Macbeth’s subconscious morality projected the act of murder as a ghost. It is a true illusion but of the psychological context. Psychology plays a deep impact on Macbeth all the text and another superficial aspect of Macbeth’s inner fears were revealed when he visualized Banquo’s dead body looking at him and he is tremendously terrified that Banquo might still be alive. This one vision or illusion appears as a striking note to Macbeth’s morality and thus expose the inner contradiction of Macbeth’s ambition, morality, justification and self doubt. (Gervers, 17-22) In conclusion it can be stated that Macbeth is a villain in many senses but a lovable villain without doubt and this contributes this character to become one of the crafted tragic hero of literature.
