Journey of the Magi Essay

Journey of the Magi has been penned down by Nobel prize winner TS Eliot an is a contrast of experiences based on the nativity of Christ. The monologue describes the journey of the Magi to Bethlahem in search of spiritual pacification and is an account of Eliot’s own conversion to Anglican faith, making the journey and objective correlation for Eliot. As per the Gospel story, the Magi were the three wise men namely Balthazar- King of Chaldea, Gaspor – King of Ethopia, Melchoir -King of Nubia who belonged to the priestly class of magicians and had come to Bethlahem to pay homage to infant Christ presenting him with gifts of gold, myrrh, and frankincense. They symbolise wandering human souls in search of spirituality, the eternal spiritual quester. The poem, ‘Journey of the Magi’ opens with the nativity sermon of Lancelot Andrews preached in 1622 which describes the hardships Magi faced due to deep ways, sharp weather, meeting snow and hostile conditions which were hard to combat : ‘ A cold coming we had of it/ Just the worst tme of the year’ in ‘the very dead of winter’. The Magus admits that there was introspection promoted for ‘there were times we regretted’ as they had given up materialistic pleasures and sensuality of ‘Summer places on the slope’ and ‘silken girls bringing sherbet. ’ Besides wondering whether it was worth the effort, their major issue of search was ignored and the day to day difficulties bogged them down with ‘camelmen cursing and grumbling’, ‘night fires going out’ and ‘villages, dirty and charging high prices’. and they admitted, ‘A hard time we had of it’. The Magi now ‘preferred to travel all night’ and faced agonising moments of self doubt : ‘voices singing in our ears saying that this was all folly’ before they finally reached a temperate valley. The second half of the poem abounds in symbolism with the temperate valley signifing the change in their lives that followed the ardous journey. They come across a ‘ running stream’ depicting the timelessness of their journey; ‘watermill beating the darkness’ continuing the image of extinction and renewal; ‘three trees signifing three crosses at calvary; ‘an old white horse’, a metaphor for rebirth of Christ, the Savior and the defeat of paganism; ‘Vine leaves over the lintel’ again symbolic of the vine that christ metamorphosed into his blood; ‘Six hands at an open door dicing for pieces of silver’ refers to betrayal of christ by Judas and lastly ‘feet kicking empty vine skins ’is symbolic of the worn out forms and rituals of the old dispensation. The Magus describes their destination as : ‘Finding the place, it was ( you may say) satisfactory’. Such a deliberate understatement reflects the turmoils in the minds of the Magi as an outcome of the clash of their old dispensation and new beliefs. The last twelve lines describe the psychological change in Magi as they wore caught in confusion and perplexity and claimed that ‘This birth was hard and bitter agony for us like Death’. The journey marked the end of their old dispensation but didnot give them satisfaction of faith for the Magus claims, ‘I should be glad of another death’ so that he may be born into a new faith. The poem can be studied at three levels : The actual journey of the Magi; Eliot’s journey from doubt to faith while his conversion to anglicanism, and journey of any individual in spiritual quest. belonging to the Ariel poems, the journey traces Eliot’s own spiritual quest and his yearing for sublime peace. The monologue reconfirms the universal truth that the brave and the dauntless who embark upon journies with conviction are graced with divinity but it is sensual jdesires and temptations that need to be overcome.

Ecoterrorist Groups in the United States Essay

Terrorism, in any form, is frowned upon by many people. However, when it is related to taking care of our environment, it could be quite controversial because environmentalism is embraced across all political spectrums. Like the right wing or left wing extremists, violent ecologists and animal rights advocates have caused some scare among people in the United States. This called ecoterrorism and some of these groups often destroy properties that they perceive beneficial to the environment and animals. As Laquer (1999) informed, the word ecoterrorism has been coined to name violent environmentalists (also called â€Å"greens† and other names) that push their ideologies and beliefs to the extreme. Their complaints are as just as those of Christians, Muslims, Jews, Socialists, Anarchists, and indeed most other ideologies and religions of our time, who cannot possibly be made responsible for the actions of the extremists within their ranks. However, in all these value systems, there are beliefs that, if carried to an extreme, may provide inspiration for acts of violence (p. 99). William Dyson (2000), a retired FBI agent who spent nearly 30 years working on domestic terrorism, says it is necessary to look at the way police officers classify crimes and the economic impact of violent ecological extremism to understand the full scope of ecoterrorism. Dyson contends most of the crimes are reported as localized vandalism. The significance of the total destruction is missed. Dyson says when the total economic impact of ecoterrorism is calculated, it demonstrates that the United States has been victimized by a long term terrorist campaign. In fact, in the testimony of FBI Director Louis Freeh (10 May 2001) about the terrorist threats in the United States, he classified ecoterrorism as â€Å"special interest terrorism†. He reasoned out that this is different â€Å"from traditional right-wing and left-wing terrorism in that extremist special interest groups seek to resolve specific issues, rather than effect more widespread political change. Special interest extremists continue to conduct acts of politically motivated violence to force segments of society, including, the general public, to change attitudes about issues considered important to their causes†. These â€Å"special interest† terrorist groups could support their belief in â€Å"extreme fringes of animal rights, pro-life, environmental, anti-nuclear, and other political and social movements†. Moreover, these groups can belong animal rights and environmental movements and â€Å"they have turned increasingly toward vandalism and terrorist activity in attempts to further their causes†. Bryan Denson and James Long (1999) have conducted a detailed study of ecological violence. They found that damage from ecoterrorism have already reached millions of dollars. They conducted a 10-month review and considered crime only in excess of $50,000. Cases that could not be linked to environmental groups were eliminated. They found 100 cases with very few successful law enforcement investigations. According to Denson and Long (1999), most violence has taken place in the American West. From 1995 to 1999, damages totaled $28. 8 million. Crimes included raids against farms; destruction of animal research laboratories at the University of California in Davis and Michigan State University, threats to individuals, sabotage against industrial equipment and even arson. History of Ecoterrorism in the United States The history of radical ecoterrorism goes back to 1980 when a group of five militants belonging to mainstream organizations such as the Sierra Club and Friends of the Earth decided, at the end of a hike, that far more drastic action was needed in view of the imminent destruction of nature, or what remained of it. To them it seemed pointless to work within the system, and thus Earth First was born (Laquer, 1999). Many Earth First activists argue that ecotage (ecologic sabotage) â€Å"can actually prevent destructive activity underway—driving the worst Earth destroyers right out of business— erasing their profits by slowing their work and destroying their tools† (Taylor 1991, p. 263). Despite the fact that ecoterrorism in the US sparked in the 1980s,, two of the most influential books for ecoterrorists were published in the 1970s. These books are Robert Townsend’s Ecotage (1972) and Edward Abbey’s The Monkey Wrench Gang (1975). Edward Abbey’s novel told the story of a group of ecologists who were fed up with industrial development in the West. Abbey is an environmental activist and not a hate-filled ideologue like William Pierce. His novel is a fictional account that has inspired others. In The Monkey Wrench Gang, the heroes drive through the Western states sabotaging bulldozers, burning billboards, and damaging the property of people they deem to be destroying the environment. Incidentally, this is the same type of low-level terrorism German leftists used in the mid-1990s. ) The term â€Å"monkey wrenching† has since became synonymous to ecoterrorism. Laquer (1999) thought that environment radicalism in the United States might have been connected with general political developments. The Carter administration in the 1970s initially was thought to sympathize with the aims of the ecologists, but these hopes proved false. The government neglected more forests to be put at the disposal of the timber industry. Environmentalists reacted in anger, which only increased as more deregulation occurred under President Reagan in the 1980s. The language of the radicals became more violent, as did the character of their actions. As one of the more radical thinkers maintained, the salvation of the earth required an end to civilization and to the vast majority of mankind. They saw human beings as no more important than any other member of the biological community, and with no more rights than animals–or, indeed, than inanimate objects such as forests, rivers, and mountains. Seen in this light, they felt it had been wrong for modern medicine to combat infectious diseases, for bacteria and viruses also had rights–as one of the ecological thinkers put it, eradicating smallpox had been immoral inasmuch as it had been an unwarranted interference with the balance of the ecosystem. Ecoterrorist Groups in the United States In the United States, the most prominent ecoterrorist groups are the Earth Liberation Front (ELF), Earth First, and the Justice Department are interested in environmental preservation. The Animal Liberation Front (ALF), Animal Rights Militia, Band of Mercy, and Paint Panthers champion animal rights. However, it is the violent groups like the ELF and ALF that advocate and engage in economic damage. The rhetorical groups, such as the Church of Euthanasia, simply border on the bizarre, advocating suicide, sodomy, and cannibalism to voluntarily eliminate the earth’s human population (White, 2003). In fact, FBI now ranks both ALF and ELF as the leading domestic terrorism groups that threaten United States, surpassing the Timothy McVeigh-style militia extremists who dominated the terrorism scene during much of the 1990s. James Jarboe, FBI domestic-terrorism section chief said that they estimated that the ALF/ ELF have committed more than 600 criminal acts in the United States since 1996, resulting in damages in excess of $43 million. Worse, the threat is growing because animal and environmental activists are turning increasingly toward vandalism and terrorism to further their causes (Richardson, 2002). According to Atkins (2004), ELF was originally formed by the dissident members of Earth First! in Great Britain in the early 1990s, an American version started operation in 1996 and allied with the Animal Liberation Front (ALF). The group took aim at targets it perceived as causing or promoting harm to the environment, from biotechnology research laboratories to automobile dealerships. In the US, they first made the national news with the arson of five buildings and four ski lifts in Vail, Colorado, on October 17, 1998. Environmentalists had been fighting the Vail Resorts over an area that was wintering grounds for elk and a habitat for the endangered lynx. Since 1997 the Southern Poverty Law Center has attributed ELF with dozens of terrorist attacks and $30 million in damages (p. 91). The Federal Bureau of Investigation (FBI) said the group had claimed credit for bombings and arson that had caused some $40 million in damage since the mid-1990s, when the group began its campaign in North America. Although no one had been injured in any of the bombings and fires, the FBI considered the ELF one of the most dangerous organizations in the country. Among the acts of vandalism and arson that the group had claimed responsibility for in 2001 were: †¢ An August 21 vandalism attack on a Long Island, New York cancer research laboratory. †¢ Coordinated June 12 vandalism attacks on five Bank of New York branches in Suffolk County, New York. †¢ A June 10 vandalism attack on the University of Idaho’s biotechnology building. †¢ A June 1 fire in Eagle Creek, Oregon, near a timber sale site in a federal forest. Two separate May 21 arson attacks, the first at a poplar tree farm in Clatskanie, Oregon, the second at the Center for Urban Horticulture at the University of Washington in Seattle. †¢ A March 30 fire at an auto dealership in Eugene. †¢ A January 2 fire at the offices of a lumber company in Glendale, Oregon (â€Å"Law Catches Up to,† 2002, p. A01). Because of ELF’s decentralized structure, this allowed separate cells to act independently of each other and its reliance on the Internet computer network to communicate, made it difficult to capture culprits. Typically, the group would claim responsibility for an act through its press office in Portland, Oregon Despite probes of the press office and the people who ran it, authorities had made little progress in seizing members guilty of sabotage. Knickerbocker (2005) presented salient proof that ELF has â€Å"guidelines† that prove their ecoterroristic activities. These include taking â€Å"all necessary precautions against harming any animal, human and non-human. † But they also include a call to â€Å"inflict economic damage on those profiting from the destruction and exploitation of the natural environment. An ELF â€Å"communique† taking responsibility for a 2002 firebombing of a US Forest Service research station in Pennsylvania declared: â€Å"While innocent life will never be harmed in any action we undertake, where it is necessary, we will no longer hesitate to pick up the gun to implement justice, and provide the needed protection for our planet that decades of legal battles, pleading, protest, and economic sabotage have failed †¦ to achieve. † Moreover, the group’s website includes a 37-page how-to manual titled â€Å"Setting Fires With Electrical Timers. † As a cousin of ELF, the Animal Liberation Front (ALF) has been described as the most militant of the American animal rights groups. It has its roots in Great Britain where a small body of activists, the Hunt Saboteurs, opposed hunting and hunters by resorting to disruptive tactics. Two activists, Ronald Lee and Clifford Goodman, decided in 1972 to resurrect a nineteenth-century antivivisection group, the Band of Mercy. After a series of anti-hunting incidents, this group changed its tactics to direct action on animal rights issues and renamed itself the Animal Liberation Front. When the group used violence against animal research facilities, furriers, and farming, Scotland Yard classified the ALF as a terrorist organization. The ALF is organized into two segments—a public organization for publicity, fund-raising, and propaganda, and a covert wing of tightly organized cells of activists willing to carry out attacks on property and rescue animals. The British group has around 2,500 active members, but only about 50 members are radical enough to carry out violent attacks. Because of the success of the British ALF operations, American animal rights supporters formed a branch in the United States (Atkins, 2004, p. 0). According to ALF’s website, animal rights criminals have a system to publicize their activities. Like all terrorists, ecoterrorists try to create an aura of power through publicity. ALF takes it further, using the Web site as a training device. For example, tactics for raiding mink farms are given in great detail. Utilizing a four-part series, an ALF member tells readers the methods for establishing and operating a cell, procedures for obtaining funds, and directions for planning and carrying out operations. However, like all extremists, their positions are full of contradictions and virtual absurdities. For example, the Web site for the â€Å"we-use-no-animal-products† ALF tells people to use leather gloves when raiding a mink farm. It also compares people who eat meat with Nazis and describes farms as concentration camps. Apparently, ALF members are unaware that Adolf Hitler was a vegetarian. Atkins (2004) reported the firebombing of the unfinished Animal Diagnostic Laboratory at the University of California at Davis on April 16, 1987, which resulted in 4. million in damages, was the most destructive operation of ALF. Representatives of the ALF never claimed responsibility for this act, but police officials have been able to uncover evidence of its involvement. Despite numerous violent operations, only two individuals, Roger Thoen and Virginia Bollinger, have been arrested and convicted for activities involving the ALF. Conclusion Ecoterrorists are uncompromising, illogical extremists just like their right-wing counterparts. A review of their ideological literature shows they use ecology as a surrogate religion (White, 2000). While not one action of ELF or ALF so far comes close to the magnitude of the attacks on the World Trade Center, the government should not ignore the threats posed by these groups. With few arrests or prosecutions have followed from the violent actions of environmentalists or animal-rights advocates, these groups may become more violent and bolder in the future. Thus, it is recommended that the US government should monitor the activities of these ecoterrorist groups and apply harsher sanctions for offenders.

Kafka’s Metamorphosis in Context to His Era Essay

  Ã‚  Ã‚  Ã‚   One of the major German writers was a Jewish, middle class resident of Prague, a man named Franz Kafka, who wrote disturbing, surreal tales. Writing in both short story and novel form, his work was published posthumously by a friend, Max Brod, who ignored his requests to burn his writings upon his death. Because his friend disobeyed his last request, Kafka’s work has become iconic in western literature, even producing its own connotations.   The term â€Å"Kafkaesque† has come to mean mundane yet absurd and surreal circumstances of the kind commonly found in Kafka’s works (â€Å"Kafka†,1).   Ã‚  Ã‚   One of the most widely read and famous of these works concerns a man who wakes up one day and discovers he is an insect. Literally. Known as Die Verwandlung or The Metamorphosis, Kafka wrote this story quickly, completing it between November and December 1912.   Ã‚  Ã‚  Ã‚   Because of its bizarre subject   matter, his tale has been subjected to a wide variety of interpretations. Although critics vary widely in those interpretations, the basic story involves a man who awakens in different form: he is now an insect; a â€Å"giant monstrous vermin;† yet all he wants to do is get to work. He has provided for his family and feels the pressure of helping them even now. However, in this new context , he cannot speak with his family members. Judging only by appearances,   his relatives becomes repulsed by him, calling him a burden. Each time he enters to try to be in their midst, they act mean; his father even goes so far as to throw an apple, which subsequently gets infected after it embeds in his back. Although Gregor becomes a veritable prisoner of his dirty, grimy room, his family does provide food and other nourishment-for a time. But they so abhor his appearance and treat him so despicably, that his sister finally declares that   â€Å" that thing must go.† His mother doesn’t even offer a word of protest. Because of his outsider status with his family, Gregor returns to his room one last time; desirous of relieving them of their burden. He lies down. And dies.   Ã‚  Ã‚  Ã‚   Both the structure and the setting of the story resemble that of a drama. The structure builds dramatically, with a series of three crises, leading to a denouement. Each section of the story has a defined area where the story takes place; a limited space as in plays.   With the exception of Gregor, the other characters are one dimensional.   Ã‚  Ã‚  Ã‚   Thus, Kafka works out of the traditional Aristotelian framework of three acts consisting of a beginning, middle, and end. Yet his style is ordinary. Has he been overrated? His plot is limited in scope, a series of episodes in the life of a character, rather than a full development. The characters are also limited. So what exactly did cause this Kafkan phenomenon?   Kafka dealt with the subject of contradiction and the absurd— with a sense of impotence against the absurd conditions and banalities of the world. Although not attracted to any â€Å"isms’ of thought philosophically, politically, artistically, or religiously, he simply expressed his own soul (Artile, 1).   Ã‚  Ã‚  Ã‚   Despite his lack of referencing, the wider world nevertheless laid claim to him.   Ã‚  Ã‚  Ã‚   The Jews saw him as their own visionary. They were convinced he foresaw the arrival of the Holocaust. Yet Kafka was not a religious Jew, going to synagogue only four times yearly with his father and having a bar mitzvah at age 13. Too absorbed in his personal frustrations to pay much attention to political developments, Kafka could not help becoming cognizant of the increasing xenophobia and anti-Semitism of those around him. He thought that Palestine was a good solution and often talked of moving there to operate a cafà © with his girlfriend Dora. In the midst of the anti-Semitic riots of 1920 Berlin, he said that â€Å"the best course is to leave a place where one is hated† (Strickland, 2). Indeed, his own three sisters all died in concentration camps, a   fate that might also have awaited Kafka had he lived rather than dying of TB in 1924.   Ã‚  Ã‚   Although only a secular Jew, Kafka was nevertheless attracted to Yiddish theatre. The Metamorphosis has many parallels to a classic work of Yiddish theater called The Savage written by Gordin. The son Lemekh in this tale is â€Å"defective† like Gregor Samsa.   Outcasts who horrify, both characters are animal like creatures in decline. The central metaphor of The Metamorphosis corresponds to  Ã‚   Lemekh’s position in his own family. As the housekeeper states, ‘they kill him if he comes in here, so he lies in his own room, days on end, with his eyes open, and stares, like an animal, waiting to be sacrificed’ (Beck, 54).   Ã‚  Ã‚   Beck continues to state that the Oedipal conflict and the larger theme of incest is present in both works because the sons’ love for their mothers and sisters become confused with sexual desire. They become dizzy when they see their parents embrace. When Zelde touches Lemekh, he gets hot. Similarly, Gregor wants to save the picture of the lady in furs, crawling up the glass which soothed his hot body. Crawling shows his acceptance of his animal state- hiding when others enter, fainting- which intensifies the action and shows strong emotion. Lemekh in his iron jacket and Gregor in his armor plated hard back are both imprisoned, and spiritually limited. Gordin’s play warns of the beast in every man hiding beneath his human faà §ade. Kafka’s work also seems to be pointing to the vermin which every man inherently embodies (Beck, 56).   Ã‚  Ã‚   Other groups besides the Jews also embraced Kafka. Psychoanalytic Freudianism and   Existentialism saw reflections of their philosophies in his works. The Freudians saw every range from dreamlike qualities and Oedipal conflicts to symbolic odds and ids. Kafka’s feelings   for his own father reads like a transparent Oedipal story. Many critics were of the opinion that never before had Freud ruled so supremely over a story as he did The Metamophosis (Eggenschwiler, 72).   Ã‚  Ã‚   Existentialism took Kafka to be one of their own .Because he created characters who struggle with hopelessness and absurdity, many in the movement saw him as an icon, while others in the group were disillusioned with the western status quo of the 50s and the 60s. They distorted Kafka by exploiting the heavy atmosphere of his stories, using them as the basis for the need of a more liberal society with less state intervention and more truth for the individual.The existentialists abused truth by portraying a psychotic Kafka, victim of their same angst. The humor and mischief that was so dear to the surrealists that he loved is lost with that existentialist label ( Artile, 7).    One of the most obvious themes of The Metamorphosis concerns society’s treatment of those who are different and   the loneliness of being cut off; the desperate and unrealistic hope that isolation brings (â€Å"Kafka,†3).   Ã‚  Ã‚   In his pain and rejection Gregor Samsa was far from being everyman. And most readers will not be prepared to accept him as a universal symbol. Nevertheless, it is hard to avoid the condition in The Metamorphosis that Kafka was demonstrating; at least at that time; his own despairing, tragicomic vision of the human condition ( Beck, 57).   Ã‚   Kafka’s value will always lie in the inexplicable that it contains. Final understanding will probably remain an   impossibility. The various mid-century groups that took him as their hero never saw the complete picture of his artistic merits or original thought. Although many of his stories are inscrutable and baffling, Kafka himself looked upon his writing and the creativity he produced as a means of redemption (Artile, 7).   Ã‚   Thus his work transcends all the various interpretations that have been forced upon it and stands on its own merits, remaining an important part of the Western canon; work that is timeless.

International Finance - Case Study Example The new equipment will have a useful life of 10 years. The equipment being replaced had a book value of Pts. 1,605,000 and a market value of Pts. 950,000 meaning a Pts. 655,000 loss on disposal. The net present value rule states that an investment should be accepted if its net present value is greater than zero and rejected otherwise. The new equipment produced by Brevetti Cea, s.p.a ,an Italian firm has a number of benefits including larger production volumes, inspection and rejection thresholds are easily adjustable and the machine does not require specially trained operators. The fact that the new machine does not need trained personnel means that new employees can within no time learn how to handle the new equipment as compared to the 2 or 3 months needed to earlier train them. The semi-automated, old model inspection equipment has operational costs of Pts. 88,496 in 1988, which are expected to gradually rise to Pts. 124,872 in 1997. The new photoelectric equipment has relatively lower operational costs of Pts. 69,676 in 1988 which are expected to rise to Pts. 98,318 in 1997. Use of the new photoelectric equipment is expected to result in savings in operational expenses . After this 10 year period, the new photoelectric equipment would have exhausted its useful life. Cash flows relevant to the new photoelectric equipment include; the initial Pts. 61.525 million or $500,000. The savings in the materials and labor cost, that is the difference in the operational costs of the old model equipment versus the new efficient equipment consists cash inflows or savings. The revenues or cash sales anticipated from assimilation of the photoelectric equipment are however unstipulated. There is also a loss of Pts. 655,000 on disposal of the old equipment, as its net book value is Pts. 1,605,000 and its market value is Pts. 950,000. Merck considers the savings

No Child Left Behind - Essay Example Next is the improvement of flexibility and local control. It also provides an increased number of options for parents. Lastly it stresses on proven teaching techniques. The phrase, "No Child Left Behind" (NCLB) has become a slogan for the federal scheme to increase "accountability" in American education. But despite the fact that NCLB is a federal plan, it will be up to the individual countries to make the plans and procedures that accomplish NCLB requirements. NCLB does not provide the new mandate with adequate funds. Thus this has an effect on opinions of many schools and parents. Many states have implemented this policy by now, but this has an impact on the parents and schools as they had to face many difficulties while coping up with the policy. This article further describes the effect, changes and pros and cons of the policy in regard to its laws.(Edwards & Perry 2004) This act generally stresses on developing American schools to a standard in which all students are given equal opportunities. As in the act it states "close the achievement gap between high- and low-performing children, especially the achievement gaps between minority and non-minority students, and between disadvantaged children and their more advantaged peers." This clearly reflects that NCLB aims to offer reasonable and equivalent opportunities to the students so that they can attain education of high standards. One of the most important terms of NCLB is the obligation that the states should set values in the field of education and should perform yearly evaluation of schools to check the progress of the school and analyze if the schools have been successful in improving the student's educational achievements. NCLB gives funds for the training of teachers; it provides special support to students who face difficulties with reading and supports immigrants and homeless students. Overa ll NCLB holds the states, districts and the schools to take accountability of the student's achievements. States are entitled to report the progress of students who suffer from problems like reading and writing. They are also directed to report about the students who are from different ethnic groups and who belong to families of low income. On the contrary NCLB has passed laws which act as a barrier for admission in kindergarten. Thus this proves to be a setback for the youth in their future. This youth may suffer from problems like aging, race difference and other physical and mental differences. A child cannot get admission in a kindergarten or a primary school if he has not cleared certain eligibility criterion (Panzica 2008). The laws implemented in the United States of America are prohibiting the children from early entries into kindergarten and primary schools. This can immensely affect the future of the children as it may determine the age of the child when he finishes his high school. There is a certain age limit for any child who needs admission in the kindergarten. If one is not able to comply with the age limits then they possibly will not get an admission into the school. The Act has made the school authorities more accountable for the results of the students and this has therefore made the authorities more conscious when giving admission to a child of less capabilities. The age criterion is so strict that the schools have a certain date setup (usually in September or December) at which the child should be of the

This act was adopted mainly to uplift the standards in corporate governance, analysis of securities and performance of audit work. According to Cohen, Dey & Lys (2007), before the introduction of this policy there were numerous Securities and Exchange Commission violations, gross lack of corporate quality control and ethical behavior in companies resulting in many corporate scandals and filing of criminal actions against corporations, shareholders, company directors, and finally company officers. The Sarbanes-Oxley Act came into effect in the wake of some of the nations enormous financial scandals. The Act is believed to initiate most of the dramatic changes to the federal laws since 1930s. It further prescribes punishment for violators of the Act ranging from prison sentences to multimillion-dollar penalties. The main idea that the editors of this act had in mind was to protect investor s by improving the accuracy and reliability of corporate disclosures made pursuant to the securities laws. Over the years, the government of the United States of America has adopted this policy and many security policies have been drafted in reference to this act. SOX applies to all public companies in the United States not excluding international companies that have registered equity or debt securities with the Securities and Exchange Commission and the accounting firms that provide auditing services to them. According to Bartlett and Richard the Sarbanes-Oxley Act has created new standards for corporate accountability and also new penalties for acts of incompliance. It has changed how corporate boards, executives and corporate auditors interact with each other. In addition, it also removes the common excuse of claiming that one was not aware of a mistake when he or she made it on matters pertaining to finances. This mainly involves the CEOs and CFOs, as it holds them accountable f or the accuracy and errors of financial statements (DMPL). The Act specifies new financial reporting responsibilities and these include adhering to new internal controls and procedures formulated to ensure that financial records are valid. The Act makes it a federal crime to for a company to force or manipulate an auditor into signing off incorrect financial statements thus preventing company directors and officers from obtaining personal benefits from dubious financial statements. Moreover, the Act stipulates that the board of directors in almost all public companies should have an audit committee. The committee is tasked to appoint, regulate, inspect and exercise control over the company’s auditing firm. As result the auditors are to directly report to the audit committee. Rationale for public policy-Market failure This highlights how the concept of market failure applies to ethical corporate governance to give an insight in corporate ethics’ authenticity in the mode rn corporation and the probability of the Sarbanes-Oxley achieving its desired results. When large companies like Enron, WorldCom and Tyco just to name a few were struck with enormous cases of corporate fraud, the necessity to find for an amicable solution was very vital. This is because millions of dollars were embezzled by the CEOs and CFOs through customized balance sheets. Companies incurred considerable loss of profits

On Target Corporation - Research Paper Example Other than food items and household essentials, all merchandise categories found in physical stores are available for sale on the online shopping site. The credit card segment offers credit and debit cards under the â€Å"REDcards† brand to qualified customers. Currently there are three â€Å"REDcard† options: Target Visa and Target Card credit cards and Target Debit card (Target 10–K Part 1). Therefore, the company’s revenue model is on sales markups from retail sales and credit card fees and interest. In the retail segment, Target’s biggest competition is Wal-Mart and Costco. However, due to the broad category of merchandise that the company offers, all other forms of retail commerce are potentially competitors. Nevertheless, Target has been able to compete successfully by differentiating itself through a combination of price, merchandise assortment, convenience, customer service and marketing efforts. An example is how Target has deployed diffe rent store formats – CityTarget, SuperTarget, Target Greatland and Target stores – to capture different customer segments. ... Networking ensures that all Target stores are interlinked such that supply chain management is effectively managed to match consumer demand. This way the company can maximise on its mark-ups while it keeps its inventory costs at a minimum. On the other hand, CRM is vital for Target’s online business as it enables the company to perform customer analytics to improve targeting and customer segmentation. Order Fulfillment Process Analysis As an online shopping site, order fulfillment is a major process at target.com. In this study we selected the most straightforward way for making an online purchase at target.com as a new customer. Order fulfillment starts immediately after online shopper has selected the item he/she wants to buy. This item is added onto a virtual shopping cart. The first input in order processing is the item to be procured. Once an item is selected Target’s system checks if the item is available within its inventory. The output is immediately delivered w ith the publishing of either â€Å"in stock† or â€Å"not available†. When you add an item on the shopping cart, target.com opens a mini-window with three options: checkout, continue shopping and view and edit cart. The next input, strictly speaking, is the selection of any of these three options by the customer. The site always provides customer with the option of returning items to cart and continue shopping as one proceeds to checkout. The next set of inputs is customer shipping address, selecting form of payment and billing address. Repeat customers may opt to create an account with target.com, in which case they would not have to keep entering any of these three sets of data each time they want to make a

Public Administration and Democratic Governance Essay

Public Administration and Democratic Governance - Essay Example Traditionally public administration has been the forte of orthodox public administrators. They believed in monopolistic policy making and forced enforcement of these policies. With "Change" occurring at rapid phase democratic governance in public administration is inevitable to provide responsive and effective service to citizens. Citizen awareness has been another driving force enabling changes in functioning of the public administration. Citizens are more demanding, ask for more out of less and have raised the bar for public administrators from just governance to good governance. This notion has moved the responsibilities of public servants from service providers to the ones responsible for greater public good and minority upliftment. The three branches of governance - Legislative, Executive and Judiciary are no more seen as separate entities, instead, their packaged service accessibility is one of the other major responsibilities of a public administrator. The drivers mentioned above lay the stepping stone for "New Public Administration" (NPM). This initiative has become a synonym for public administration's effort towards democratic governance aiming to achieve greater economic and social development. The self governance process introduced by NPM is driven by innovation at all levels intending to face the turbulent dissatisfaction environment. Decentraliza

My Attitude to the God is Dead Phrase of Friedrich Nietzsche Essay - 8

My Attitude to the God is Dead Phrase of Friedrich Nietzsche - Essay Example As a result, he argues that God can only do things that other humans can do. He also argues that God can die. He specifically argues that ‘there was only one Christian, and he died on the cross’ (p. 109). This further shows Nietzsche’s opinion that the founder of Christianity, who was crucified, never resurrected. According to Nietzsche’s history, he was a learned person, a professor, and the people whom he associated with were also respected. Wagner, whom he saw as a father, for example, influenced him. Their relationship however ended because he revolted against him. Nietzsche then tried to establish a love relationship with Lou Salome but the relationship did not succeed. This negatively affected him and he resigned from his work at a university. He then wrote a number of books before suffering from mental illness in the year 1889 and meeting his death in the year 1900. A majority of his writings discredited Christian religious beliefs. I do not agree with Nietzsche’s opinion because of many reasons. While Nietzsche argues that all humans, including God, should be treated equally, he does not appreciate the possibility that God may be the creator of the universe. He also does not explain an alternative origin of nature to oppose the possibility that God created the universe. This, therefore, means that he believes that God has supernatural powers that created the universe. If God created the universe then he has higher powers than any other creature. Therefore, Nietzsche’s opinion that God and other beings are equal is not true. Similarly, his opinion that there existed only one Christian is not true. This is because a Christian is a person who follows the doctrines that Jesus Christ taught. History identifies a number of people who devoted their lives to following the doctrines. Many people also follow the doctrines of this generation.

Psychology of Racism Essay Example for Free

Psychology of Racism Essay In 1892, a shoe maker named Homer Plessy from New Orleans Louisiana was arrested for refusing to transfer to a railroad car designated for the dark-colored population in the East Louisiana Railroad after he sat in a first class railroad car meant for the white-skinned constituents of the state. Plessy appealed that he should be considered white since only 1/8 of him was African American as it was substantiated in his heritage. According to him, by forcing him to transfer to a different car, the authorities were violating the 13th and 14th Amendments of the United States Constitution which impedes slavery and segregation. From local custody to Supreme Court, Plessy was tried and accused of civil disobedience (Elliot, 2009). The arbiters of the court exhibited linear cognition which disregarded Plessy’s plea of violation of rights and obstinately favored Luoisianas claim that they did not violate such Amendment of the United States Constitution since they have the right to imply regulations and policies in railroad stations that are within their state. The case was denied of opportunities to be studied sufficiently as the justices esteemed and acknowledged that the act of separating the races under impartial rights should be abided, setting aside the sentiments of the colored inhabitants. II In South Campton County Virginia, a group of African American slaves initiated a rebellion that killed about 57 white men, women and children before the military forces and a number of armed civilians were able to arrive and take control. Angered by the murder of almost more than 50 innocent lives, vigilantes eradicated dozens of slaves who were not involved in the insurrection and exiled hundreds of free colored people from their land. The leader of the insurrection was a literate African American slave named Nat Turner who claimed he saw visions of God telling him to commit this act of violence, and with his extraordinary power of persuasion, he was able to compel other slaves to join him. After Turners surrender on October 30, 1831, he and his men were executed. (Bernier, 2010) Following the death of Nat Turner, a year of debate relating to the status of the African American slaves congested the Virginia General Assembly. Although it was considered that they should be relieved from their abject duties as slaves, a systematic arrangement for their freedom was never formed. Nat Turners act of rebellion caused that an anti-literacy law be passed which diminished the African American slaves freedom to communicate and have the opportunity to be educated, thus, almost completely mutilating their already restricted rights. From that historical event which became known as Nat Turners Rebellion or South Campton Insurrection, it can be analyzed that it might not only be a visionary or a delusioned mans whim that caused such barbaric deeds but possibly an act or cry for liberation. Unequal treatment, enslavement for the rest of a mans life and forced labor for very minimal or no wage at all, these are acceptable factors that can be considered as parts of a motive for the rebellion in South Campton. III In 1803, a British convict settlement was established in a Tasmanian aborigini inhabited island called Van Diemens Land. A total of of 65,000 convicted men and women were settled in the island of which most of them were cruelly traumatized and extremely violent. Due to the incompetent procedure of punishment, convicts were able to take flight into the Tasmanian hinterland where they exerted the fullness of their brutality and thirst of blood upon the aboriginis of the island (Turnbull, 1948) Symbolically and appropriately, this event in history can be described as a case of rape as the innocent aborigines were violated of their rights and freedom to live accordingly. Not only were they conquered and treated as slaves in their own land but they were exterminated and murdered like animals. They were robbed of their privilege as humans and left their race at the brink of their extinction. References Bernier, C. M. (2010) Slave Heroism in the Transatlantic Imagination.

A Network Technology And Data Communications Information Technology Essay

A Network Technology And Data Communications Information Technology Essay A WAN, or Wide Area Network, is a network that covers a large area, for example computers on opposite sides of the planet communicating. Usually, WANs are 2 or more LANs (Local Area Networks) connected together. One of the most well-known examples of a WAN is something we all use every day: the Internet. Types of WANs PTO Switched Services Here I will look at some of the most commonly known examples of PTO Switched Services. Circuit Switching Circuit switching is based on the sender and receiver making the most of the full communication channel for the length of the communication. This type of switching can be found in the Public Switched Telephone Network (PSTN) where telephone calls are started by the person dialling but arent completed until the person receiving the call answers. The main advantage of circuit switching is that it is extremely reliable for what it does. Another advantage is that once the connection is set up, it is fast to use and relatively error-free. The disadvantages include the cost of the initial set up and the time that it takes to set up the particular channel. There is also the chance of a failure at one point causing a disruption in all communications. Lastly, although there are many paths available, you can only communicate on one path at a time, meaning that if you want to talk to someone else you will have to start the process again, in the same vein once a path is established that channel will be unavailable to other users. To attempt to overcome the problems of circuit switching, packet switching was introduced. Examples of Circuit Switching PSTN PSTN, or Public Switched Telephone Network, is a circuit-switching network that uses internationally agreed codes and unique identifiers (telephone numbers) to operate. The PSTN network was originally made for fixed-line analogue telephone systems but the PSTN is now almost completely digital and also incorporates mobile telephones alongside analogue ones. ISDN ISDN, or Integrated Services Digital Network, is a communications standard used internationally to send data, including voice and video, over digital or regular phone lines, at the same time. One of the most well known uses of ISDN is for Internet access, with ISDN providing a maximum speed for upload and download of 128 Kbit/s. Leased Lines A leased line is a symmetric telecommunications line connecting two locations for voice and/or data communications. Unlike PSTN lines, leased lines dont have a telephone number; instead each side of the line is permanently connected to the other. Usually, leased lines are used by businesses to directly connect offices that are far apart, however shorter distances are also used for convenience. The main difference between leased lines and dial-up connections is that a leased line is always active. The main advantage of leased lines is the guarantee of a high level of quality, this is because the connection doesnt carry anybody elses data. Packet Switching Packet switching is a communications method that works by splitting the data being sent into smaller chunks, called packets. When the data is sent it can end up being sent through different paths to arrive at its destination. Each time a packet goes through a switch, router or adapter it is buffered and queued, which can slow down how quick the packets arrive at their destination, which also means the order of delivery can also be different. Examples of Packet Switching X.25 X.25 is one of the oldest packet-switched services that are still available and used, although it is now being replaced by less complex protocols, like IP (internet Protocol). It was developed before the OSI Reference Model so the protocol suite is essentially just three layers, which are almost the same as the lower three layers of the seven-layer OSI model (Physical, Data and Network layers). X.25 is designed to operate effectively regardless of which systems are connected to the network. It is typically used by telephone service providers which allows them to charge their customers based on their use of the network. Frame Relay Frame relay is a telecommunication service geared towards cost-efficient data transmission between local area networks and wide area networks. Frame relay sends packets at the data link layer of the OSI model rather than at the Network layer. A frame can use packets from different protocols such as Ethernet and X.25 and is also variable in size with some being as large as 1000bytes or more. Frame Relay was originally a stripped-down version of X.25, but managed to distance itself from the error-correcting which is most commonly associated with X.25. Instead when Frame Relay finds an error, it just drops the packet. Frame Relay works on the basis of shared-access and uses a technique known as best-effort, where error-correction is almost obsolete however there is also no guarantee of reliable data delivery, instead it leaves the error correcting to each end of the connection. SMDS SMDS, or Switched Multimegabit Data Service, is a telecommunications service that provides connectionless, high-performance, packet-switched data transport. As SMDS is neither a protocol nor a technology, it means that it can support standard protocols and communications interfaces that are using current, as well as future, technology. SMDS can use either fibre or copper-based lines and works on the data link and physical layers of the OSI model. Mobile and Broadband Services The greatest change to WANs and most internet services in the near future is expected to be the rise and increase of quality in mobile and broadband services and standards. ATM ATM, or Asynchronous Transfer Mode (ATM) is a data link as well as a network layer circuit switched protocol which is connection based. For example a logical connection has to be made between both end points before data can start to be sent or received. ATM also divides the data being sent into small sized cells, each consisting of 53 bytes (48 Bytes for Data and 5 Bytes for Header Information). The process of splitting the data into a fixed size is what makes ATM different from packet switched networks that use different length packets, like IP. xDSL DSL, or Digital Subscriber Line, provides customers with digital services through their telephone system. The x simply means that there are a range of different DSL technology available. DSL is probably the most used method for people to access digital services, such as the internet as it is cheaper than leased lines and also faster than ISDN, with speeds of upto 1.5Mb/s download speed and 128kb/s upload speed available on ADSL (Asymmetric DSL). This is down to the fact that DSL uses a digital modem rather than an analogue one, meaning that the data doesnt need to be converted before it is sent.

How Does Digital Radio Work Computer Science Essay

How Does Digital Radio Work Computer Science Essay Digital audio broadcasting, also known as digital radio and high-definition radio, is audio broadcasting in which analogy audio is converted into a digital signal and transmitted on an assigned channel in the FM frequency range. DAB is said to offer compact disc (CD) quality audio on the FM (frequency modulation) broadcast band and to offer FM-quality audio on the AM (amplitude modulation) broadcast band. Digital radio works by combining two digital technologies to produce an efficient and reliable radio broadcast system: An audio compression system, called MPEG, reduces the vast amount of digital information required to be broadcast. It does this by discarding sounds that will not be perceived by the listener for example, very quiet sounds that are masked by other, louder sounds and hence not required to be broadcast, and efficiently packages together the remaining information COFDM technology, (Coded Orthogonal Frequency Division Multiplex) ensures that signals are received reliably and robustly, even in environments normally prone to interference. Using a precise mathematical relationship, the digital data signal is split across 1 536 different carrier frequencies, and also across time. This process ensures that even if some of the carrier frequencies are affected by interference, or the signal disturbed for a short period of time, the receiver is still able to recover the original sound. The interference which disturbs FM reception, caused by radio signals bouncing off buildings and hills (multi-path) is eliminated by COFDM technology. It also means that the same frequency can be used across the entire country, so no re-tuning of sets is necessary when travelling, or taking a portable receiver to a different area. Instead of having a different frequency for each radio station, digital radio combines several services together in what is called a multiplex. The multiplex is able to carry stereo and mono radio channels as well as services such as text and data. The UK has been allocated seven multiplexes by the Radio Authority in the spectrum 217.5 230.0 MHz. It is possible to carry more services on this one frequency allowing the spectrum to be used more efficiently. The multiplex has a gross capacity of 2,300,000 bits which are used for carrying audio, data and an in-built protection system against transmission errors. Of these about half the bits are used for the audio and data services. Throughout the day, the data capacity allocated to each service can be varied by the broadcaster. Each multiplex can carry a mixture of stereo and mono audio services and data services too; the number of each dependent on the quality required. A multiplex is a technical term used for a number of stations sharing just one frequency to transmit its services. It is a digital transmitter located within a region broadcasting stations operated by a company or group (e.g. BBC, Digital One, Switch Digital etc). So what are DABs benefits and the cost Listeners in most major towns and cities in the world and it can receive between 30 and 50 radio stations with digital radio, in many cases thats more than double whats available on analogue. And its not just more of the same the content within that choice of stations is unique and exciting, delivering station formats that just dont exist on analogue. The FM spectrum is so clogged right now that theres no room for new stations that would expand listeners choice with, for example, soul music, or country music, or big band swing, or any of the other 100+ brands that are available uniquely to DAB. Digital radio receivers have a screen on which stations can transmit information via Dynamic Label Segments (DLS). Some stations already transmit the latest news, travel, and weather, whats on now and next, Web site addresses and phone numbers. Tomorrows radios will offer much more sophisticated data. The potential for advertisers to use the DLS facility on DAB for targeted advertising is an exciting prospect, and in the future, advertisers can use DAB to deliver Internet-type commercials. Because digital radio uses the spectrum more efficiently than analogue, it is possible to broadcast more channels using the same frequency, making room for broadcasters to expand their station portfolios. It also offers less noise. DAB digital radio delivers improved sound quality. The technology allows the receiver to lock on to the strongest signal it can find and ignore everything else. This eliminates the hiss, crackle and fade so familiar on analogue radio. A BLOCK DIAGRAM OF A DAB RADIO http://focus.ti.com/graphics/blockdiagram/blockdiagram_images/6243.gif This diagram above is about what goes on in a DAB radio. In order to receive a station the Low-Noise Amplifiers (LNA) boosts the RF signal from the antenna. The frequency synthesizer generates a Local Oscillator (LO) signal that is mixed with the RF input to form the IF signal. The high-speed ADC converts the IF signal into digital samples. Depending on the speed of the signal the DAC outputs as compared to what the DSP or microcontroller can handle, a Digital Down counter may be required. The power supply is connected to the 12V or 24V board net and regulates down/up to voltages for DSP, uC, memory and ICs and functions in the infotainment system. In some cases there may be 10 or more different power rails, making the design of the power supply a critical task when trying to design for size, cost and efficiency. Linear regulators with low quiescent current help reduce battery leakage current during standby operating modes (ignition off), are load dump voltage tolerant for directly battery connected devices, and need low drop out and tracking for low battery crank operation. Beyond providing increased conversion efficiencies, switching power supplies provide EMI improvement with slew rate control of the switching FET, Frequency hopping, spread spectrum or triangulation method for attenuation of peak spectral energy, Low Iq, soft start for power sequencing and in rush current limitation, Phased switching for multiple SMPSs regulators to minimize input ripple current and lower input capacitance, higher switching frequency for smaller components (L and Cs), and SVS functions for brown out indications The Audio input front end and audio output is often combined into a single Codec. On the output side ADCs convert the digital output an analog signal, which is amplified to the levels needed by the speakers or headphones used with the system. By using Class-D amplifiers the systems power efficiency can exceed 90% while maintaining low THD. This improved efficiency leads to significant size, weight and heat reductions. TIs class-D car audio solutions exhibit extremely low EMI levels and are being used in OEM systems with stringent EMC requirements. The audio DSP performs I/Q demodulation and outputs digital audio and data. This includes functions like volume, treble, bass and sound effects. THE COMPONENT OF A RADIO TRANMITTER WAVE A transmitter can be defined as an electronic device which, usually with the aid of an antenna, propagates an electromagnetic signal such as radio, television, or other telecommunications. http://www.hardware-one.com/reviews/dab/DRS-small.gif A transmitter can be made by coupling the output of an oscillator directly to an antenna. The primary purpose of the oscillator is to develop an rf voltage which has a constant frequency and is immune to outside factors which may cause its frequency to shift. The output of this simple transmitter is controlled by placing a telegraph key at point K in series with the voltage supply. Since the plate supply is interrupted when the key is open, the circuit oscillates only as long as the key is closed. Transmitter http://www.tpub.com/neets/book12/0059.GIF Capacitors C2 and C3 can be GANGED (mechanically linked together) to simplify tuning. Capacitor C1 is used to tune (resonate) the antenna to the transmitter frequency. CA is the effective capacitance existing between the antenna and ground. This antenna-to-ground capacitance is in parallel with the tuning capacitors, C2 and C3. Since the antenna has capacitance, any change in its length or position, such as that caused by swaying of the antenna, changes the value of CA and causes the oscillator to change frequency. Because these frequency changes are undesirable for reliable communications, the multistage transmitter was developed to increase reliability. Reception of a DAB signal The DAB ensemble is selected from the antenna to the analogue tuner, the output is fed to the demodulator and channel decoder to eliminate transmission errors. The information contained in the FIC is passed to the user interface for selection and is used to set up the receiver appropriately. http://www.hardware-one.com/reviews/dab/fig3.jpg Receiving of DAB signal RATIO DETECTOR The ratio demodulator uses a double-tuned transformer to convert the instantaneous frequency variations of the fm input signal to instantaneous amplitude variations. These amplitude variations are then rectified to provide a dc output voltage which varies in amplitude and polarity with the input signal frequency. This detector demodulates fm signals and suppresses amplitude noise without the need of limiter stages. The input tank capacitor (C1) and the primary of transformer T1 (L1) are tuned to the center frequency of the fm signal to be demodulated. The secondary winding of T1 (L2) and capacitor C2 also form a tank circuit tuned to the center frequency. Tertiary (third) winding L3 provides additional inductive coupling which reduces the loading effect of the secondary on the primary circuit. Diodes CR1 and CR2 rectify the signal from the secondary tank. Capacitor C5 and resistors R1 and R2 set the operating level of the detector. Capacitors C3 and C4 determine the amplitude and polarity of the output. Resistor R3 limits the peak diode current and furnishes a dc return path for the rectified signal. The output of the detector is taken from the common connection between C3 and C4. Resistor RL is the load resistor. R5, C6, and C7 form a low-pass filter to the output. Ratio detector http://www.tpub.com/neets/book12/0261.GIF This circuit operates on the same principles of phase shifting as did the Foster-Seeley discriminator. In that discussion, vector diagrams were used to illustrate the voltage amplitudes and polarities for conditions at resonance, above resonance, and below resonance. The same vector diagrams apply to the ratio detector but will not be discussed here. Instead, you will study the resulting current flows and polarities on simplified schematic diagrams of the detector circuit. What is amplitude modulation? Amplitude modulation (AM) can be defined as a technique used in electronic communication, also is use as transmitting information via a radio carrier wave. AM works by varying the strength of the transmitted signal in relation to the information being sent. In order for a radio signal to carry audio or other information for broadcasting, it must be modulated or changed in some way. Although there are a number of ways in which a radio signal may be modulated, one of the easiest, and one of the first methods to be used was to change its amplitude in line with variations of the sound. The basic concept surrounding what is amplitude modulation, is quite straightforward. The amplitude of the signal is changed in line with the instantaneous intensity of the sound. In this way the radio frequency signal has a representation of the sound wave superimposed in it. In view of the way the basic signal carries the sound or modulation, the radio frequency signal is often termed the carrier. What is amplitude modulation, AM Amplitude Modulation    When a carrier is modulated in any way, further signals are created that carry the actual modulation information. It is found that when a carrier is amplitude modulated, further signals are generated above and below the main carrier. To see how this happens, take the example of a carrier on a frequency of 1 MHz which is modulated by a steady tone of 1 kHz. The process of modulating a carrier is exactly the same as mixing two signals together, and as a result both sum and difference frequencies are produced. Therefore when a tone of 1 kHz is mixed with a carrier of 1 MHz, a sum frequency is produced at 1 MHz + 1 kHz, and a difference frequency is produced at 1 MHz 1 kHz, i.e. 1 kHz above and below the carrier. If the steady state tones are replaced with audio like that encountered with speech of music, these comprise many different frequencies and an audio spectrum with frequencies over a band of frequencies is seen. When modulated onto the carrier, these spectra are seen above and below the carrier. It can be seen that if the top frequency that is modulated onto the carrier is 6 kHz, then the top spectra will extend to 6 kHz above and below the signal. In other words the bandwidth occupied by the AM signal is twice the maximum frequency of the signal that is used to modulate the carrier, i.e. it is twice the bandwidth of the audio signal to be carried. Amplitude demodulation Amplitude modulation is one of the most straightforward ways of modulating a radio signal or carrier. The process of demodulation, where the audio signal is removed from the radio carrier in the receiver is also quite simple as well. The easiest method of achieving amplitude demodulation is to use a simple diode detector. This consists of just a handful of components:- a diode, resistor and a capacitor. AM diode detector AM Diode Detector In this circuit, the diode rectifies the signal, allowing only half of the alternating waveform through. The capacitor is used to store the charge and provide a smoothed output from the detector, and also to remove any unwanted radio frequency components. The resistor is used to enable the capacitor to discharge. If it were not there and no other load was present, then the charge on the capacitor would not leak away, and the circuit would reach a peak and remain there. POWER SUPPY Most of the Dab radio is use by batteries. Also there three parts is a battery which are an anode (-), a cathode (+), and the electrolyte. The cathode and anode (the positive and negative sides at either end of a traditional battery) are hooked up to an electrical circuit. http://www.qrg.northwestern.edu/projects/vss/docs/media/Power/battery.gif The chemical reactions in the battery cause a build up of electrons at the anode. This results in an electrical difference between the anode and the cathode. In a battery, the only place to go is to the cathode. But, the electrolyte keeps the electrons from going straight from the anode to the cathode within the battery. When the circuit is closed (a wire connects the cathode and the anode) the electrons will be able to get to the cathode. In the picture above, the electrons go through the wire, lighting the light bulb along the way. This is one way of describing how electrical potential causes electrons to flow through the circuit.

Proclamation of student concerns :: essays research papers

Proclamation To Address Student Concerns About The Medium News Letter: Preamble: Presented on this day, November the nineteenth, in the year two thousand and three, as members of the Rutgers University community who are concerned and dissatisfied with the subject material that has been printed in the magazine The Medium, a student funded organization, we collectively agree that the following measures need to be met and addressed with as much cooperation as possible to facilitate in the propagation of unity amongst Rutgers University students, faculty, and staff. Rutgers University’s mission statement, as defined through the following excerpt, is required to be applied to every Rutgers University organization. All Rutgers University organizations are asked to abide by the mission statement of the university in order to foster a community that is cohesive and indivisible: â€Å"Rutgers, The State University of New Jersey is committed to the ideals of excellence in fostering an enriching learning community of students, faculty and staff from a broad spectrum of nations, cultures, and historical perspectives. Diversity is an integral component of human experience, and encompasses but is not limited to issues of race, ethnicity, culture, social class, national origin, gender, age, religious beliefs, sexual orientation mental ability, and physical ability. Our collective goal is to create an institutional consciousness of diversity reinforced with equity and excellence through our policies, practices, and programs of inclusion, non-discrimination, and pluralism for all members of the University Community.† WHERE AS:  Ã‚  Ã‚  Ã‚  Ã‚  The mission of the university is stated above, The Medium must question its current relevance to the university’s mission. While membership is not neglected on the basis of â€Å"†¦race, sex, handicap, age, sexual orientation, or political and religious affiliation (Medium Constitution)†, the publication itself does not agree with the university’s mission, nor does it provide an outlet for diversity and respect of other cultures, races, and sexual orientations. WHERE AS:   Ã‚  Ã‚  Ã‚  Ã‚  The Medium has published and continues to publish ‘hate speech’, the environment in which said magazine has and is creating one of racial hostility. Community lines are drawn due to racial, religious, gender, and sexual orientation differences, causing the Rutgers University community to be disjointed and without proper unanimity and accord. WHERE AS:   Ã‚  Ã‚  Ã‚  Ã‚  The Medium has fostered an atmosphere of antagonism, the safety of students, regardless of color, creed, gender, and sexual orientation are in danger. Although opinions are without credit to those they might endanger, the physical sight of such opinions places the Rutgers community in a state of alert and fear.

Angel :: essays research papers

TO MY BEST FRIEND Without you, high school would not have been the same. Over the years we have shared so much and built a relationship that is precious and lasting With you I can laugh, I can cry, I can say what’s on my mind or just be silent. With you it’s easy to be me. I remember disagreements....saying things we didnt’ really mean. I also remember that only minutes later we were laughing so hard we cried. Sometimes when life seems difficult...I remember our friendship full of laughter and love. Then I am able to lift my spirits and smile like I know you want me to. The memories we share remind me of how lucky I am to have a best friend like you. People we meet see a little of you in me and a little of me in you. I look at you and my eyes look back, I speak and I hear your voice. We are more than merely acquaintances....it’s as if we are cut from the same fabric. We have a common thread that won’t be broken--by people, or years, or distance. We are never at a loss for words. We can talk for hours about nothing at all or communicate the deepest hurt with a single word. With you, speech is effortless and laughter is contagious. You bring love and light, kindness and caring, cheer and support into my life. We do not always see eye to eye....sometimes we take different roads. Our relationship is not always perfect, but when we have a problem it’s surmountable. Sometimes we are the mirror image of each other and other times we couldn’t be more opposite. But because of you I know myself better. I know that if I pick up the phone you’ll be there. If I need help, you’ll give it to me twofold. If I start to go down the wrong path, you’ll lead me the right way. There’s no end to what you do for me and I want you to kow I’ll do the same for you. Thank you for listening without judging and for giving advice without pushing. Thank you for helping me gain confidence in myself to stand alone--and for letting me know you’ll always be there. The greatest part about being best friends is sharing ourselves. Having our own interests, but always communicating. Striving to meet our own goals, but never losing sight of one another. Living our own lives, but always remaining connected. You and I have so many memories...you share my history. You remember where I’ve been, respect who I’ve become and encourage me

Cell and Molecular Biology

Cell and Molecular Biology Final Name: Hadeel Binomar30 pts. Protein misfolding can be an aspect of several different human disorders, including cystic fibrosis, Alzheimer's disease, and atherosclerosis. Many times, the misfolded protein is a membrane protein. In fact, a type of diabetes insipidus results from a mutation in the G-protein-coupled vasopressin 2 receptor that prevents the protein from making it to the cell membrane A) Describe how this type of receptor would normally get targeted to the membrane (from the beginning of translation) and B) then propose one mechanism by which the mutation could cause a lack of proper targeting. One of the most important protein's target is G protein-coupled receptors, several signaling mechanisms depend on this type of receptor to change both internal and external stimuli to the intracellular responses. Basically, one of the G couple receptor subfamilies is G-coupled Vasopressin-2- Receptor (V2R), and this receptor is going through a strict quality control process at the endoplasmic reticulum, which presents the only correctly folded protein to gets through the secretory pathway. The primary function of the V2 receptor is to activate the attached G protein that bound to the ? subunit then phosphorylated to GTP. The G protein couple receptor then activates the enzyme adenylate cyclase that catalyzes the reaction in the ER and forms cAMP from ATP. After that, cAMP acts as a second messenger and activates a protein kinase that phosphorylates the integral membrane proteins on the cell surface. Moreover, the secretory pathway organelles' and the plasma membrane both are first introduced into the Endoplasmic reticulum, and the co-translationally proteins that can cross the ER are synthesized by the ribosome first then binds by chaperones to gets moves to the ER surface using GTP that allows them to move toward the receptor then release it. The soluble proteins and the integral membrane proteins as I mentioned above, can be targeted through the ER and then translocated by the same mechanism.Further, several mutations occurring in the transmembrane region which affect the structure of the protein. These are multiple mutation sites, such as mutations occurring in the amino acid residues which was acting as a causative agent for human disease. Also, there are other mutations occurring on the single site position that will affect the translation mechanism and cause many human diseases like: cystic fibrosis, Alzheimer's disease, and atherosclerosis that proves the function of V2R protein which plays important role in the translation during the protein folding process. One of the mechanism that may a reason for lacking the proper target protein is when the mutations of the CFTR gene occurring and affect the function of the chloride ion channels and cause defect in the protein sequences which lead to the production of diseases and misfolded of the proteins that are unable to recognize their functional destinations. Otherwise, Lack of the stop signals is another issue that prevents the protein from getting into the surface of the ER, also called the non-stop decay cellular pathway, because lack of this stop signals prevents mRNA from synthesis and translate the proteins, these consider as a point mutation that inhibits the essential stop codons. 30 pts. Describe the experiment shown in figure 3 from the paper we discussed in class (Miller et al, 2003). (A) In your description, consider the following questions: Why did they do it? How did they do it? What did they learn? (B) Diagram the results that you would expect to see in Lanes T, 1, 2, 3, and 4, if the amino acid signal DID in the protein Gap1p was mutated to random amino acids and tell why; and (C) Give two possible (different) results that might occur if the amino acid signal LxxLE in Bet1p was mutated to the amino acids DID (which are the signal in Gap1p). Diagram the results expected in Lanes T, 1, 2, 3, and 4 and explain why you predicted this result for each case.left20840701.A001.A4467225201739500The experiment was performed to study the role of cargo binding domain of Sec24p in the process of protein sorting. To perform this study, both mutant and wild types subunit Sec23/24p and Sec23/24L616W were harvested from microsomal membranes. The immunoblotting assay performed to quantify cargo molecules using radio-labeled secondary antibodies. Comparison of the mutant subunit with wild type illustrated omission of some molecules in mutant one, these molecules were cargo protein molecules. While some of them are packed in a way that similar to the wild-type. It meant that there were some signals that remained unaffected although mutation was there. Unexpectedly, it was found that in these unaffected molecules of mutation in Sec23/24p, packaging was better than the wild type. Further, they found the proteins that were highly affected had Bet1p and Gap1p/Sys1p chimera, because they completely depending on the Sys1p di-acidic of COPII vesicles. If the amino acid signal DID in the protein Gap1p was mutated to random amino acids, the resulting bands would be seen as in figure 1. A because the amino acids might be present in all the lanes. And Gap1p is required for di-acidic motifs to fuse together with the COPII vesicles at the mutated domain. Also, Sys1 peptide is not involved in Sec 23/24p hence its mutation is not contained in a di-acidic motif. If the signal LxxLE was mutated to the DID, the expected Bet1p packaging would be shown in figure 2. A as not be seen in lanes containing Bet1p because the amino acid signal LxxLE does not exit after mutating to amino acids DID. The second probability for the Bet1p would be expected to bind with the vesicle for packaging when it interacts with di-acidic motifs which is needed as shown in figure 2.B290512515621000581025113030004781550412752.B002.B6286501346202.A002.A20 pts. Explain the experiment shown in Figure 5C from the Shen et al. (2018) paper on the phosphorylation of CDC25 that we discussed in class. In addition, be sure to also address the following: A) why did they do this experiment (the central issue); B) what did they learn; and C) what is another control experiment they could have done? D) Would these results change if you added a constitutively active form of LKB1 to the reaction? If so, how and why? A) Overall, the main purpose of this paper is to explain how the division of cells is highly regulated such that cells that fail to pass some specific stage-based tests cannot advance to the proceeding stages. In this particular experiment, HeLa cells were subjected to chemicals that are known to activate the enzyme AMPK. Also, the main catabolic processes that are involved to generate energy for cells to transition from G1/G2 were determined by the application of radiochemical approaches, the experiment required to approve how highly conserved cellular energy sensor can significantly delay mitosis entry and activation of AMP-activated protein kinase (AMPK). Further, Wee 1 family inactivates the cell cycle G2/M Phase which is controlled by Cdc3/cyclic B (mitotic cyclin-dependent kinase complex). They found that AMPK-dependents phosphorylation of CDC25C arranges a metabolic control point for the M-phase transition and the cell cycle phase G2. B) Also, they learned that suppression of Wee 1 or acute induction partially reinstates mitosis ingress in the circumstance of activated protein kinase (AMPK). This experiment showed that when Phosphorylates Cdc25 is in a distributive and disordered state, it results into ultra-sensitivity in protein phosphorylation. C) For another control experiment, they might try exposing the U2OS (cell line) clones conditionally exhibiting Cdc25A etoposide. That will help to test whether Cdc25A degradation is significant for the G2 control point or not.D) If they add an active form of LKB1 to the reaction, the results will not change, because in cells LKBI activity inhibits AMPK activation in response to different stimulations. Also, LKBI is lost upon consistent isolation and therefore no effects of phosphates observed.20 pts. Briefly describe the role of cyclin-CDK in the cell cycle and give an example of positive and negative control in this system. Also, describe how cell cycle regulation links to the stimulation of apoptosis at the molecular level. In the beginning, the cell cycle depends on many basic factors that control the regulation process starting from the signal transcription molecules, growth factors and the Cyclin Dependent Kinases enzymes include the checkpoints which control the transition process between the cell cycle phases by binding to the cyclin proteins CDKs then phosphorylate other proteins to transfer from one phase to another. The role of transcription factors is to turn on the signals for gene expression, DNA replication, and cell divisions. As an example of CDKs, cyclin-dependent kinase 1 CDK1 is a cell division cycle protein homolog 2, that has a primary role in human cancer cells because CDK1 rather than any types of CDKs is fatal to the mutated version of MYC- dependent cancer that leads to a depletion of oncogenes like (Fos and Jun) in human cancer cells. Fos and Jun are combined forms of the transcription factor called AP1 that activates the delayed response genes such as cyclin D and CDK4. Recent studies reveal that the reason for the MYC breast cancer cells duplation is targeting CDF1 exhibit any other CDKs cell lines. Also, CDK1 inhibition can control and target the cancer cells in human and both phosphorylation and expression of MYC during the cell cycle process. To initiate intracellular signaling pathways and stimulate the cell cycle entry, mitogens substance bind to the cell surface receptor with the activation form of GTPase Ras that activates MAP kinase cascade. That will lead to the expression of encoding gene of the transcription regulatory protein like MYC. Moreover, E2F transcription factor is a target for cyclin D and CDKs that stimulate proteins expression to initiate S phase, also E2F regulated by the tumor suppressor gene Rb (Retinoblastoma protein). At early G1 Phase, Rb protein combined with E2f to form the histone deacetylases protein that remains chromatic condensed, then cyclin kinase phosphorylates Rb protein, causing it to disassociate from E2F. That allows recruitment of histone acetylates, which decondense the chromatin and helps transcription complexes to form in G1 and S phase and to form a positive feedback. For the negative control, if there are no growth factors present to stimulate the synthesis of Cyclin D in the new cell, Rb phosphorylated will turn off, and Rb will rebind to E2F, then the cell cycle will stop and that will lead to many negative results like prevent it to bind with DNA, or DNA damage and cells will return to the G0 phase. Apoptosis is a consequence of DNA damage; if the damage is not repaired, the cell cycle will divert towards apoptosis, otherwise, if the cell has DNA defects and fail to undergo apoptosis, that will change to the cancer cell. G1 phase regulators such as P53 and E2F are essential to promote the cell regulations and eliminate any damage or abnormal changes during the cell cycle. P53 has a primary function to prevent any mutation in DNA during cell progression, so any defect in P53 will lead to cancer, and it's usually mutated in cancer cells. Further, Rb protein considers as a tumor suppressor and also promotes apoptosis. Additionally, most human cancers have inactive Rb protein, either mutated Rb or the non-phosphorylated (inactivated form) of Rb protein

Osama Bin Laden Research Paper

Osama Bal pixilated the mastermind of 9/11 Christian Hanker December 21 , 2012 introduction History Period 1 Osama store load substituted the macrocosm on September 1 1, 2012, when he orchestrate the 911 1 bombings on the ground wiliness center in impudently York City. He has in any case trendulated galore(postnominal) a(prenominal) nigh other attacks including the October 2000 attack on the US Cole, and attacks on the US embassies in Nairobi, Kenya, and Dark sees Salaam, Tanzania in 1998 (Encyclopedia of piece 1).Osama salt a representation adulterate had a negative Influence on societies, economies, and theology throughout the world because of his actions in masterminding umteen a(prenominal) musical theme terrorist attacks, and because he created and ended al- stem. Osama put in cockeyed had a dramatic launch not tot wholey on the caller of the unite States plainly e trulywherely general. These radical attacks hold back returned in changes to the port parliamentary law carrys business, travel, Immigration, and most Importantly, how the bang-up unwashed view and aver each other. Simply sic, it has in many ways contributeed in a forceful change to many pluralitys behavior.The attacks of 9/1 1 resulted in join ond certification exponentially. later these attacks, airport guarantor was amplified. new(prenominal) security mea reals were Implemented such as e rattling time someone fly they are required to undergo torso scanning they hire to remove property and belts, and all liquids everyplace three question four apothecaries ounces must be jammed in checked luggage Mon currently 13). tout ensemble these measures are now enforced to verify maximum safety and security in airports. Instead of macrocosm adapted to pushover through the airport and board their flight, plurality are required to be on that heighten two hours early. Which has become a infallible inconvenience and a time eat practice. After t he 9/11 attacks, raft were very hesitant to fly because they were afraid. To attention ease the anxiety of flying and put to death the safety sys precautions, the Nun deed t States created the Transportation Security Administration. The TTS hired over 50,000 heap to work in airports crosswise the country and buzz off found to determine over fifty one thousand thousand nix items, 5,000 of them being firearms Monsoon 7-10). Since Osama Bin Aldens various attacks, some airlines alike Canada 3000 and Swiss Air were on the verge of going bankrupt.To counteract this, the airlines crammed more than seats in their airplanes, cut the free food service, and reduced flights Monsoon 22). This inconveniences the passengers because there s less space and comfort on board and with less flights, not everyone whitethorn get a seat on their flight. Osama Bin loaded had a strike impact on the way we travel, has put anxiety in the minds of inculpable people wanting or needing to travel o n an airplane, and ca apply changes in the way commercial airlines conduct businesses.Osama Bin crocked has change parliamentary procedure cosmopolitan through the lives bewildered in 9/1 1 and the Statess fight on terrorism. Osama Bin besotted was trust deservingy for the many deaths that occurred as a result of his terrorist attacks. In the wake of 9/1 1, approximately 3000 people died ( reinvigoratedspapers 1). This not only affected the people that died, only as well as the people that love them, witnessed their death, their neighbors, the community approximately them, and also the world. An enormous amount of heartbreak was felt throughout the world and many societies were humbled.Another way Osama Bin stiff has wedge high lodge is the number of legions, oddly the Statesn, that have been displace to Afghanistan and Iraq to fight in the war on terrorism. Approximately 70,000 troops were sent to Iraq and Afghanistan (Encyclopedia of World 23). This affected bo th their suffer lives and also their loved ones, not astute if they are alive, outing a great amount of fear in millions of peoples lives worldwide. The court of the war on terrorism has not only been human lives.Governments across the world have had to fund the increased deployments and postulate revisions in their budgets for the future. Finally, there has been a outsize death bell shape incurred by unbiased Muslims living in both America and on the battlefield. In retaliation to the 9/11 bombings, many Americans discriminated against Muslim Americans and many cases resulted in violence. Muslim lives have been anomic fighting for AY-Qaeda and innocent civilians eave died, being caught in the middle of this war. Osama Bin Laden is trusty for changing society and the lives of many Americans, troops and his own fol subverts.Osama Bin Laden left field his mark on society by his role in inflicting terror into the black Maria and minds of people worldwide. What is so frighteni ng about(predicate) terrorism is that it could happen anywhere and anytime. Bin Laden used this advantage of closed book to plant the seed of fear into peoples minds worldwide. In October 2001, according to a Gallup poll, forty 6 percent of Americans said terrorism was Americas biggest trouble (Grief 47). This shows that Osama Bin Laden has had an enormous and unchanging decide on the way Americans ring and why they may do authentic things.Osama Bin Laden had such a great influence on Americans and their minds that the CIA released a bounty worth $25 million for Bin Laden. bran-new York City governance put posters up around New York City show again how much the capture of Osama Bin Laden was worth to America and how much he had affected society. This is evidenced in figure one, showing that officials want Bin Laden curtly or alive. Osama Bin Laden undone megs of peoples peace of mind worldwide. The 9/1 1 attacks were carried out in conditions of day-to-day manners, which was in essence using the particle to surprise as a weapon.What is more terrifying is that he managed to install his people into our communities. These terrorists lived amongst us until Osama Bin Laden gave his orders. This efficaciously created a feeling of mistrust and paranoia subsequentlyward the 9/1 1 attacks. It for certain had a great impact on the state of mind of many Americans. Osama Bin Laden impacted society by influencing the modification of the security systems, being trustworthy for killing thousands of people, and outing terror in millions of peoples minds worldwide.While Osama Bin Laden had an extraordinary influence on how people around the world feel and behave he also had a negative impact on Americas preservation. One way Bin Laden left his mark on the united States economy is that his actions caused the joined States to spend billions of dollars for the military, defensive measure, and security sectors. In the years of 2006-2008, military expense increased by $540 million to add on weapons and transportation to fight the war on terror and to deploy troops into Pakistan and Afghanistan to engender Bin Laden (Griffin 17).This broad expense would not have been incurred if Bin Laden had not execute the attack on the World flip-flop amount. These funds could have been spent on other things, like paying off the national debt or providing better education and healthcare for American citizens. Not only did Bin Laden cause the join States spend inessential money on finding him, but he also affected society by redistributing $540 million of potential support which could have been used in improvements in society. This money was spent on defense and the security sectors.All three of these divisions boosted the United States debt to $14. cardinal (Burger 8). Osama Bin Laden cost the United States lots of resources, money, and time in the essay for their peace of mind. Osama Bin Aldens actions have caused friction amongst half way eastern and western countries, reproduction the white plagues of odds from these nations, in particular oil. After the 9/1 1 attacks, the membrane-forming relationship between Islamic countries and America made Muslims reluctant to trade, resulting in an increase in the oil worth. Before 9/1 1, oil prices were $1. 3, per gallon but they have increased to a incumbent price of $3. 65 per gallon (Mille 16). Obviously, with the price of gas skyrocketing by over $2 after 9/1 1, resources have become very expensive to withstand and has put many Americans in unwieldyies financially because it is a huge increase that has to be accounted for. Other resources such as bullion have experienced price increases. At the time of the 9/1 1 bombings, gold was priced at $271. 5 per ounce however it is now very expensive, rebellion to $1821 per ounce (Mille 13-14).The price of gold after 9/11 has risen over 600%, fleck the American dollar has befogged one third of its value. Since the 9/1 1 attacks, he increased price of many plentiful goods within the Middle East has made it more difficult for people to pay for them. Another way Bin Laden affected The United States economy is due to his role in planning the destruction caused which resulted in the reparations the policy companies owed, and the time and money spent cleansing the devastation.Firstly, in the attacks that killed over 3,000 people, it cost an estimated $1. 5 billion to clear the devastation where the World Trade Centre stood (Gaffing 13). This cost in clearing the remains, moving it and disposing of it was a bigger expense which otherwise would have been used on other necessary expenditure such as education or roads. These funds were spent on an issue that could not have been predicted or budgeted for. The cost to America can also be accounted in for the time to thousands to workers and the tort to volunteers.Another way this incident affected the economy is in the damages claims that were owed to millions of people. These insurance claims include life insurance, auto insurance, and property insurance. The combination of lives lost and damage of properties led to and estimated $40 billion price tag in insurance claims (Gaffing 7). This huge toll on insurance companies made many companies bankrupt, and if not bankrupt, premiums became very expensive for people wanting to leveraging insurance.The cost of disposing and clearing the site where the World Trade Centre stood and the insurance claims incurred after the attack crippled the economy, especially that of New York City. After the attacks of 9/1 1, many other struggles within the United States economy arose. One example of this is that the unemployment rate in the United States almost doubled. Prior to 9/1 1, the unemployment rate was four layover nine percent but soon after, the unemployment rate rose to nine point one percent Mille 7-8).As a result of the terrorist attacks over 600,000 Jobs were lost, 226,000 of them in the travel manufacture (Mille 7-8). This huge cut of workers left many people struggling to survive, becoming homeless, and relying on welfare or other sorts of presidential term aide to survive. With a large shoot for supplies to aid homeless people, this increased the United States debt even further, setting the debt deeper by the millions. Thousands of elflike businesses were destroyed by the wreckage in New York City, from the collapse of the World Trade Centre and financially.Approximately 18,000 small businesses in lower Manhattan, particularly around the site of World Trade Centre, were either physically destroyed by flying debris or financially crushed without income to offset the costs to heal their shops (Gaffing 8). These small businesses were particularly hurt because they did not have large cash reserves or other stores to make sure they were earning money. Instead, they were out of business for six weeks while repairs were being made in lower Manhattan.This le ad to the large amount of unemployment that occurred and also left many people bankrupt. The attacks of 9/1 1 that Osama Bin Laden formulated had a demoralizing toll on Americas economy by increase unemployment, destroying small businesses, skyrocketing the prices of goods and forcing America to pay hundreds of thousands of dollars to understand safety and to find the man piece of ass all the chaos and devastation. Osama Bin Laden was a very influential soulfulness and he used his power to change his religion for the worse.One way that he did this is that he encouraged a violent form of Islam called Salamis. With his extreme wealth, inheriting $300 million at age thirteen when his baffle died (Encyclopedia of World 4), ND power, he has influenced millions of Muslims to get his ideas and beliefs that encouraged violence. In Osama Bin Laden Jihad against Jews and Crusaders, Osama Bin Laden encourages Muslims worldwide that it is their duty religiously to kill all Americans and th eir allies whenever possible (bin laden, Osama).Bin Laden promoted a very extremist form of Islam and was able to spread it throughout the Muslim world. He proposed to kill other people because they were of a different religion and belief, even though they may be innocent of any religious hate crimes. He executed these attacks in many different ways, including bombings, assassinations, and cyber attacks (AY Qaeda 2). This added to his repertoire as being very dangerous and helped his followers strive for their missionary work of the Jihad.He was very intolerant to other religions and cherished others to tallow in his pate Laden changed views about religion and religious tolerance worldwide by increasing the stereotypes towards Middle Eastern or Islamic people being terrorists. Many forms of violence against Muslims or people with dark skin and dark pig occurred after 9/1 1 in retaliation for the attack. Osama Bin Laden therefore negatively affected religion, because innocent Musl ims are being discriminated against because of Bin Laden attacks. Osama Bin Laden had a huge negative influence on religion, the economy, and society worldwide.
