Research Paper on Why So Many Failed Drug Tests with Athletes in

On Why So Many Failed Drug Tests with Athletes in Professional Sports - Research Paper Example School level education programs are really essential to increase athletes’ awareness of the negative effects of substance abuse and thus to create an anti-doping culture. Please find enclosed my article titled, â€Å"Failed Drug Tests with Athletes in Professional Sports† for your kind perusal. This overview of the alarming issue of drug abuse and falsified performance tendencies among athletes makes an empirical study of the scenario with a list of actual cases and citations for the relevance and accuracy of the material. This article exposes the real facets of the influence of the contrabands at the core of reality with a belief that investigative studies in the field of ethical and health issues may be encouraged for the benefit of a transparent sports world. While being aware of the very fact that complete elimination of performance-enhancing drugs is not practical in the near future, a few recommendations are suggested in the article to regulate the management of global sports for total dope-free competitions. Apart from addressing the issue from a social and individual perspective, for the compilation of this article, names of several prolific sports personalities who have been defamed for having failed tests for doping or substance misuse have been mentioned. Although the references are not deliberate, it is expected that the inclusion of such names will mark a symbolic effect among the readers about the social and professional destruction caused by this evil tendency. Thus, with due humility and appreciation for your excellence, I submit this article before you. I hope the compromises made at meeting the standards at different areas may be excused and this work will be considered for a favorable approval. Professional sports have been a primary area of concern for most of the developed countries since ancient periods because they perceived sport activities as an opportunity to demonstrate their

A research proposal on sporting and its personal development Essay The usual playing adds little value to an individual. Sport, however, helps in the development of athletic as well as the physical abilities. Sports involve team work which adds value to the social context of an individual, the way of relationship with team members and how one perceives himself. The presence of a coach in a game helps in the control of various lessons that sportsmen learn in the field of play. The coaches help in the examination of values, designing of activities considering various results as well as leading through examples. This work will address various types of development related to sports including â€Å"physical, intellectual, social, and emotional as well as moral capabilities† (Barez 2008). Problem statement Different people have different opinions on sports and sporting activities. However, it is well known that sports lead to development of certain positive qualities including self discipline, dedication and leadership skills through the competitive participation in various events. On the other, a number of people also argue that sports do not have a positive result on character development due to the win ego. In this case, the mentality for a must win leads to unethical behaviors including excessive cheating, aggressiveness and drug abuse. This makes the real value of sports very complex and worth a discussion topic on this paper. However, the pros outdo the cons and the paper will discuss on sports as a development activity. Sports help in the physical development through balancing the mind, body as well as the spirit (Holt 2008). Literature review  In the early childhood as Bares (2008) states, sporting which is mostly in form of play helps in learning skills including running and jumping as well as balancing. This also helps in gaining and development of social, emotional, moral and cognitive competencies. This helps the children to learn the rights and the wrongs. As a result this develops the individual creativity in addition to the physical development (Bares 2008). In this case, winning is not the major factor but the child engages in sporting activities for fun, enjoyment and normal participation. In this case, success is contributed through fun and creativity. The participation in various roles under different games helps in stimulation of the child creativity and imagination. The children are in a position of exploring as well as interacting with the environment. This is in addition to testing their motor skills, interaction and solving of problem individually (Holt 2008). In the middle childhood, sporting becomes a regular activity for children. Sporting helps in development of confidence in various areas including â€Å"social, emotional, mental and physical aspects. † This helps them in mastering and neglecting the negative influences. Sporting at this level also help in cooperation and competition that are constructive. In addition, it works in the independence in solving conflicts and being responsible (Murphy 2005). During the early adolescent stage, the children experience various body developments and this could be coupled with emotional stress and instability. Sporting helps the teenagers to control their emotions and making of responsible choices. During sporting activities, the exchange of information helps in development of communication skills which helps them in expression and solving of problems (Barez 2008). Sporting helps in literal interpretation and respect where one learns to adhere to various rules. There is a schedule that must be followed for exercising and this works in building of responsibility where one should also be committed and able to persevere. During various competitions, sporting helps the teenagers to develop self control as well as respecting others where one is able to accept wins with humility as well as losing. Teammates are supportive and this with various other traits goes beyond the field to the individual ways of living (Murphy 2005). In the late adolescent, according to Barez (2008), sporting plays a major role where teenagers are involved in various decisions making including â€Å"personal relationships, higher education, vocational training and career activities. Various hardships like â€Å"unemployment, financial strains, career confusion, unsatisfactory work experiences and lack of family support† among others pose a great threat to individual life. Sporting helps in provision of increased levels of self esteem, perseverance and self discipline. Sporting helps in supporting self competence and independence. However, sporting in itself is also a career and work as source of income. Through sporting one establishes his personal goals as well as career objectives (Barez 2008). Conclusion  Sporting is a major part of personal life which helps in achievement of high life standards and expectations. First, sporting acts as a motivational tool which works in encouragement and development of effective learning methods. It helps one to have specific life goals and objectives by focusing on training goals which calls for self discipline and responsibility. One is able to work without supervision with consistency which calls for commitment for performance. One is able to undergo great perseverance and can approach problems with confidence.

Terrorism and the Effects on Security Policies Essay -- Terrorism

â€Å"No state responds to a terrorist campaign without changing its institutions and hence society itself, even if only slightly,† Stephen Sobieck states in his chapter on Democratic Responses to International Terrorism in Germany. Politically motivated terrorism struck the heart of both Germany and Italy in the 1970’s and 1980’s causing each state to do exactly what Sobieck stated. Both countries, unfortunately, suffered severe casualties, infrastructure damage, and threats from right and left wing terrorist organizations triggering these countries to adopt policy changes. This included a restructured legislation, the addition of new laws, and the modification current laws. Both countries political agendas and perceptions caused significant complications affecting each state’s ability to handle the rising threat. Germany’s political setting suffered intense rivalry between the two levels of government: the Bund (national government) and the La nder (states). Italy had similar political struggles on the perception and ideology of terrorism impacting the country. The dominated Christian Democratic Party (DC), whose primary goal was to pleas the public opinion, viewed terrorism based off political interests. The two rival parties, whose strength grew towards the end of the 1970s, included the Italian Communist Party (PCI) and the Movimento Sociale Italaino party (MSI). It took the Italian political classes five years to alert themselves seriously to the problem of terrorism. With the issues facing the political parties, both countries inappropriately utilized their security forces.

Synthesis

The idea of gender wage discrimination being widely practiced in the United States today is a difficult concept for many to swallow. With the Equal Pay Act of 1963 and Title VII of the Civil Rights Act of 1964, the realization of the existence of the gender wage gap surprises many Americans. These authors bring to the forefront the idea that there is more to the gender wage gap then just companies discriminating against women and minorities. They sight many sources with defined data including Burres and Zucca who looked at database information from 1992 through 1997 and confirmed that just over 3% of women held a position in the top 5 spots in most companies. Furthermore, the pay for executives showed women’s salaries were considerably lower than those of their male counterparts (Kennedy, Nagata, Mushenski, &Johnson, 2008, p. 13-14). This fact alone directly affects the productivity of the workplace, causing resentment and discontent with female employees. Add to the issue those women with disabilities and the percentages of discrimination raise a staggering fifty percent. The authors also showed evidence of wage discrimination against African Americans, adding to the argument that female African Americans are fighting an even tougher battle then white women (Kennedy et al. , 2009, p. 14). The authors provide arguments as to why these wage differences still exist, sighting Hartmann, Gault, Lovell, Sinzdak, & Caiazza (2003) who claim the most prevalent reason is fewer hours worked. Women have other responsibilities with family and home that pull them away from work, which in turn gives them less experience and training, justifying a lower salary. Even in the last 40+ years women have been working their way into male dominated positions, yet their wage is still 23. 5% lower than their male co-worker (Kennedy et al. , 2008, p. 15). Another argument is that of social and professional networking playing a part in the wage differences. Most evidence leans toward the concept that networking is beneficial in securing higher paying positions. It also showed that white men were more apt to promote other white men than women or other minorities. Yet, women with powerful social or professional connections were also able to secure higher paying positions. Other minorities seemed to have lower socioeconomic status and thus had difficulty in obtaining higher paying positions (Kennedy et al. , 2008, p. 15-16). The authors also touch on the idea that women are less apt to boast about their accomplishments, or pat themselves on the back, effectively letting their superiors know about positive situations, or client successes. Women also tend not to negotiate salaries therefore leaving money at the negotiating table and keeping their salaries lower. There is also mention of the correlation between emotions and pay reviews, being that women respond to positive feedback with more satisfaction then that of monetary compensation, thus failing to acquire the much deserved pay increase. These facts may address a small percentage of the wage gap, but in no way explain away the entire 23. 5% difference (Kennedy et al. , 2008, p. 8). If fighting the battle of wage discrimination isn’t enough, then take a look at how the laws are written. Both the Equal Pay Act of 1963 and Title VII of the Civil Rights Act of 1964 put the burden of cost and the difficulty of proof on the employee, making the chance of winning almost impossible. The government needs to provide assistance to those facing this unjust, and assist at all levels, state and federal to enforce and prosecute those crossing the line (Kennedy et al. , 2 008 p. 14). Equal pay to all could bring harmony and cooperation to the workplace, which could encourage higher production and increased revenue, proving that elimination of gender wage discrimination is a healthy change for the economy (Kennedy et al. , 2008 p. 14). All of these arguments play into the idea that if the gender wage gap was completely eliminated the economy and the government would benefit. Education, experience, networking and negotiating all play a part in the difference in pay, but as pointed out in this article, those arguments do not justify the 23. % variance. Equal pay also promotes women to a higher pay scale and removes many single parents from government assistance, in turn saving to government money. Higher pay and abolishment of gender wage discrimination means more taxes, more discretionary funds available for spending, decreased resentment in the workplace and positive teamwork, which could result in higher productivity equating to a stronger economy.

Kiowa Indians essays

Kiowa Indians essays The earliest written mention of the Kiowa Indians, of the mid-west plains, was in 1682 by Ren Robert Cavelier who heard of them from a captive Pani slave, boy at Fort St. Louis who called them Manrhouts and Gattacha. The Kiowa are a group of warrior plains people who lived on the southern Great Plains. They became known as expert hunters, horse riders, and warriors who were feared for their raids on other Indian groups (SIRS). It is said that they were first discovered by Saynday, also know as Trickster, who was wandering alone on the sunless earth when he came upon the Kiowas living underground. He helped them crawl up though a hollow cottonwood tree and pulled the from a small owl hole. He had pulled a lot out and a pregnant woman got stuck in the hole and they couldnt get her to come free so the rest of the Kiowa got stuck in the ground, that is why today there arent very many of them (Starwolf). As a result of the Medicine Lodge Treaty of 1867, the Kiowa were assigned to a reservation in Oklahoma in 1868. They never really confined their activities to the reservation, however, and in 1874 resumed warfare with the white settlers in the vicinity. It wasnt until around a year later, when a large number of their horses were captured and destroyed, and several of their leaders were captured that the Kiowa were defeated (Virginia Haase). The Kiowa hunted buffalo for food, clothing, supplies, shelter, and even pictures. Like the Comanche, they lived in tee-pees, which are very easy to move, and being nomads this helped the Kiowa out greatly. They moved mainly to follow buffalo herds because buffalo was their most important source of food, they also ate plants, roots, and berries when they ran out and couldnt find anymore buffalo, women doing the gathering, men the hunting. Now The Kiowa did realize that buffalo were very important to them so the respected a...

Essay on Robotic Surgery Essay Example

Essay on Robotic Surgery Essay Example Essay on Robotic Surgery Essay Essay on Robotic Surgery Essay Surgery techniques are advancing with developing technology. Robotic surgery is getting more common day by day. Robotic surgery is a technique in which a surgeon performs surgery using a computer that remotely controls very small instrument attached to a robot. Even though it could be claimed that robotic surgery is a expensive to start-up and perform maintenance, is a longer surgery method that manual surgery, which reduces the sense of touch, in fact it contains better technique and faster healing in surgery, also, bleeding is reduced, scars are smaller and hospital stays are shorter. Although it could be argued that robotic surgery is a very expensive method, but using this technique makes easier the surgery procedure for patients. At this early stage in technology, the robotic systems are very expensive. With improvements in technology, the system will become more complicated and the cost will rise. Also, to start-up the system is highly expensive. Another issue with cost is the problem with regarding the system as they improve. The absolute cost for robotic operations was higher, the major part of the increased cost was attributed to the initial cost of purchasing the robot and yearly maintenance. However, there are various advantages of robotic surgery. Robotic arms maket he procedure easier for surgeon. Different kind of instruments can be attached to robotic arms according to procedure to be performed. Robotic techniques are also associated with reduce duration of hospital stays and pain medication. While it could be asserted that robotic is a longer surgery method than manual surgery, nevertheless, in surgery, patients feel less pain and their scars are smaller. Robotic assisted heart surgery can take nearly twice the amount of time that a typical heart surgery takes, but this is variable depending on the surgeon’s expertise and practice with the equipment. In a longer surgery, the patient is under anaesthesia for longer and it costs more to staff the procedure. On the other hand, the most significant advantages of robotic surgery to the patient is the decrease in pain and scarring. The procedure is less painful and is associated with a quicker recovery. Since the incision required are small, it does not leave a larger surgical scar when the wound heals. Although it might be contended that in a robotic surgery, the operator can not sense the surgery area, however, bleeding is reduced patient can heal faster. Some of the other drawbacks are related to its use. The surgeons lack the tactile or haptic sensetaion while using this device. This has been considered by few surgeons as hindering factor as the natural feeling of operating is lost. Otherwise, surgical technology optimizes chances of experiences quicker recovery time opposed to surgical operation. The smaller incision required to manuever the operating arms heal much faster. Because of smaller incision in surgeries, the blood loss of patients reduced. Thanks to reduced bleeding, patients recover faster. In conclusion, it is obvious that robotic surgery is the only way to safe operation. Because of better technieques and faster healing, robotic surgery should be more common.

How to Kill Your Darlings

How to Kill Your Darlings How to Kill Your Darlings This August, Simon Woodward published his fifth book, Dead Weapons. During the writing process, Simon faced a struggle familiar to many writers: should he follow his creative instincts or tailor his novel to enhance its marketability? In this article, Simon talks about the act Faulkner’s coined â€Å"killing your darlings,†   and discerning the difference between making clever marketing decisions and self-censorship.Where do you get your ideas from?Most writers have been on the receiving end of this question; the go-to question from friends and family when discussing their writing career. I admit I've never been able to answer this because, well... I don't know.The idea for my novelMy new novel, Dead Weapons, emerged from a soup of ideas and influences that had bubbled away in the back of my brain for a year. One of the main influences was Blur's song, â€Å"Kids With Guns,† and its haunting chorus: â€Å"They're turning us into monsters.† In my mind, it evokes the frightening statistics around the rise in teenage knife and gun crime in London - quoted, adjusted and recalculated in the media, then used by some right-wing commentators to create a public image of a feral generation.  Both of these contributed to the idea for a dystopian novel based around an aging society that has collapsed into a  terminal suspicion of the youth, leading to a permanent child curfew. Finally, the book’s original title had been on my mind from the get-go: And This Boy Loved His Gun. This title was the piton I used to hammer into the rock face, and to haul myself up that 80,000-word edifice. The title is the piton that hammers into the rock face, and hauls you up the 80,000-word edifice. As soon as I had this title, I knew I wanted to write a story for this 'feral generation' of teenage boys. I wanted it to be a dark, contemporary adventure, powered by a cinematic narrative (accompanied by an imaginary thumping bass), and I wanted it to be from their viewpoint. I wanted to return society's suspicious and fearful gaze from the teenagers’ perspective.Writing for a challenging demographicFrom the outset, I felt I was taking on a challenging project: the presence of the words boy and gun in a YA book title was likely to elicit knee-jerk reactions from  some,  and although I wanted to write this story for the teen demographic, there was no guarantee they'd want to read it.Highlighting the second issue was a 2016 Neilson Book Research investigation that reported a decline in teenagers who regularly read for pleasure - in particular amongst boys.  The report identified the battle for attention with social media, YouTube, the gaming industry and even good old-f ashioned television. When interviewed, boys of all ages named video game/app integrated books as the key thing that would encourage them to read more.I don't own the rights to any video games or killer apps, and so I resolved to give them the closest thing I could. Dead Weapons’ hero is Ciaran Richards, a sixteen-year-old boy framed for murder. On the run from the police, a powerful gangster, and a secret government department, Ciaran has a malfunctioning, intelligent revolver stuck to his hand - making him the literary version of a first-person shooter from computer games.  However, the last he wants to do is use the gun. He wants to let it go so he can go back to his life, but he can’t.Determining the marketability of my bookWhen my agent approached publishers with the book, several editorial directors were keen to take it on, but in each case marketing departments squashed its chances  at the acquisitions stage. I suspect that this had something to do with the subject matter and those two words sitting close together in the title. Perhaps it wasn't self-censorship after all, but a classic case of a writer refusing to cut or change something that didn't serve the story. Maybe I'd forgotten an essential piece of writing advice. As Stephen King said in On Writing (paraphrasing William Faulkner): â€Å"Kill your darlings, kill your darlings, even when it breaks your egocentric little scribbler's heart, kill your darlings.† "Even when it breaks your egocentric little scribbler's heart, kill your darlings.† - Stephen King Please share your thoughts, experiences, or any questions for Simon Woodward in the comments below!Dead Weapons is available in paperback and on Amazon Kindle.

Philosophical Ethics Final Project Research Paper

Philosophical Ethics Final Project - Research Paper Example However, the current society has witnessed high levels of abortion because moral standards have gone down. Additionally, laws that permit abortion have been enacted in several countries especially when the mother’s life is threatened. Abortion in ancient history In the ancient era, abortion practices were tolerable in Greece and Rome. Safeguarding of the unborn life was a matter of consideration only if the father was interested in the child. Children conceived outside wedlock, or bore to prostitutes or with other men other than their husbands were killed pre and post birth. Several western countries held the belief that abortion was acceptable between 18-20 weeks or before embryo movement. As a result, most women who fell in these categories procured abortions to save themselves from anguish and embarrassments. Abortions and contraception were unsafe. In pre-colonial America, there were strict laws regarding pre marital sex. Consequently, abortions were procured and the issue kept secret. Only in cases where the mother’s life was at risk was abortion legal. In 1973, the Supreme Court judgment legalized abortion in America in the case of Roe vs. Wade (BBC journal 23) Philosophical Aspects of Abortion Aristotle In order to understand Aristotle’s view on abortion, one has to understand his nature. He was a kind, hardworking and devoted man. In his quest for knowledge and information, he observed practicality and societal processes using a keen eye. Many people described him as fair and calm. Most Aristotle’s views were rooted in his belief for equality among all people and the need to follow natural law. He said that abortions performed before the onset of life and sensation are permissible. According to him, the onset of sensation and life begins forty days after conception for males and eighty days for females. He iterated that abortions procured before forty days after conception are allowed and those after are illegal and inhuman. Many scientists said that his remarks are pro life because he focused on embryo development at that time. They also argue that had he understood the scientology behind embryo development as the current society does now, he would have been against abortion. He stated that, â€Å"As to the exposure of children, let there be a law that no deformed child shall live. However, let no child be exposed because of excess population, but when couples have too many children, let abortions be procured before sense and life has begun† (Pangle 5) John Stuart Mill and Jeremy Bentham The two renowned philosophers, Mill and Bentham justified abortion using the idea of utilitarianism. John Stuart Mill came up with the happiness principle. It states that the most desirable things are pleasurable and free from pain. Utilitarianism is based on the consequences of human actions. The philosophers advocated for actions whose consequences are good irrespective of the motive. Bentham was a principled hedonist who thought that pain is quantifiable using calculus calculations. In his calculations, the tendencies of committing an action are measured using seven different factors. For Stuart Mill, the quality of pleasure was the defining factor. He believed that the good can only be defined using the level of pleasure. Utilitarianism supports abortion and concentrates on the outcome and not action. In this approach, a woman who conceives through rape has the choice of terminating the pregnancy or keeping it to term.

Three to four paragraphs - Assignment Example rth America was in Roanoke Island, the English later set up colonies in some parts of North America and the Caribbean in the early seventeenth century. The first English colony to be taken by force was the Spanish colony of Jamaica after the English colonists seized it from Spain in 1655 (Cook). The Spanish pattern of Colonization was based on religious conversion and the control of the military forces of their colonies. The French pattern of colonization was based on the stimulation of the church, state, and the control of the military forces. The French settlements depended on the trading of fur rather than by agriculture, while the primary purpose of settlement of the English and Spanish colonists were based on agriculture. The Spanish pattern of colonization was based on the principle of mercantilism, which meant that the colonies supplied market and materials and ease the home nations on reliance on other countries. This meant that, the Spanish colonization impeded trade amongst the locals and imposed high taxes upon the locals. The French pattern of colonization was based on imperialism as they dominated the political, military and the economic spheres of their colonies. The English colonization was also imperialistic in nature. Unlike the French colonists, the Englis h colonists were more prepared to grant independence to their colonies. The Spanish colonists also did not grant independence to their colonies until the colonies fought for their independence, especially the Spanish colonies in South America. The English colonists settled in the eastern seaboard of North America and they were faced with stiff competition from the French colonists, which colonized most parts of Canada. The French colonists settled in Quebec, Canada in 1608 and they claimed Louisiana for themselves in 1682. The French and Spanish settlers were largely Roman Catholics and they tried to convert their colonies to Roman Catholic, while the English settlers were purely Protestants,

Occupational health and safety Essay Example | Topics and Well Written Essays - 750 words

Occupational health and safety - Essay Example OSH increases workplace productivity. This is because OSH stipulates that all organizations have the duty of care of ensuring that employees and other parties who may be affected by organizations undertaking are safe at all times. Moral obligations in this case involve the protection of the lives and health of employees. Because of measures that are put in place in respect to moral obligations, employees become less susceptible to injuries and harm and thereby making the realization of a more secure, sustainable and healthier workforce. This in turn leads to abated levels of absenteeism, heightened motivation and ultimately, improved productivity. It is against this backdrop for instance that the European Agency for Safety and Health at Work (EASHW) established the finding that for every Euro that is invested in OSH, the Return on Investment (ROI) that is realized falls between 3 and 5 Euros, due to reduced costs that stem from reduction in absenteeism. In the US, the issue of absent eeism is underscored by the data that released to the same effect. Specifically, the United States Bureau of Labor Statistics established that machine-related accidents and injuries alone claimed 64,170 cases that required long sick-offs, in 2008 alone. Similarly, more than a fourth of these injury cases required more than 30 days being spent away from work (Reese, 2008). The fact that following OSH stipulations entails the installation of workplace risk prevention and the enhancement of proper health and safety management means that cases dealing with serious harm and injuries on employees are assuaged. Cases where these injuries are commonly recurrent are concomitant with high employee turnover, as organizations are compelled to look for another source of manpower or skilled labor. Adhering to OSH in turn alleviates cases of terminal injuries and thereby reducing the chances of high employee turnover that would be incurred as an organization tries to replenish the size of its work force. In a closely related wavelength, adhering to the standards and stipulations set by OSH gives organizational productivity the quality of continuity and stability. With the aforementioned abated cases of injuries and harm on employees, a corporate entity is succored from the task of having to retrain and nurture fledgeling personnel to acquire the necessary skills and experiences that an injured team possessed. This is significant, since training and nurturing organizational workforce entails numerous workshop drives and training programs. Reese (2008) points out that an organization also benefits directly when it adheres to OSH regulations and standards. This benefit takes the form of increased security from the ravages of workplace accidents, malfunction and human error. This is because; OSH is broad enough to include interactions with other subject areas such as safety engineering, chemistry and industrial engineering. This is especially more pronounced in industries that ha ve inherently high proclivity to accidents such as mining, construction and crisis management which have over time developed safety procedures and methods as a way of managing physical danger at the workplace. For instance, since 1992, engineering workshops specializing in welding of components are to adhere to the Personal Protective Equipment (PPE) regulations, and thereby curtailing high chances for

The Pain of Animals Essay Example | Topics and Well Written Essays - 500 words

The Pain of Animals - Essay Example His position is that humans tend to rationalize their behavior and in doing so justify our mistreatment of certain groups of animals with no thought or concern for their inherent right to life; rather in our selfishness we too often have little regard for their well-being and quality of life. In order to substantiate his position he drew parallels through various instances of how humans either assume animals do not have emotions and can not feel pain or disregard the truth believing the human race is somehow entitled to do as they please in the name of science or sport. Drawing first on the experimentation of insects in the furthering of science Suzuki concedes that somehow that may be justifiable, but then further builds on the examples of experimentations on mice, rats, guinea pigs and other rodents to further both the medical and behavioral sciences and asks us to consider if this is the point at which the line should be drawn morally and ethically. In further defense of his position he talks about how humans are conditioned to have little disregard for the other animals with whom we share the planet. Man at one point, hunted and fished to sustain his own and his family's lives. Somewhere we have gone beyond that. We hunt and fish now not just for survival, but for sport, sacrificing the lives of animals just for our own amusement and pleasure not out of necessity.

Morality Assignment Example | Topics and Well Written Essays - 500 words

Morality - Assignment Example Morals became so obscured in this day and age that people does not only neglect to practice it but also not sure of what it means. Stanford Encyclopedia of Philosophy defined it as â€Å"some codes of conduct put forward by a society† and these rules are central in formulating ethical theories (2011). We now often hear ethics in class and to put it in proper perspective it was defined by Kant’s deontology that posits that the best way to act morally to act from duty with the consideration of the highest good, that is, acting through the moral determination of the will. Kant’s acting through the moral determination of will meant that the motivation of one’s action must be pursue the good without condition which is intrinsically good by itself (Kant 30). He formulated his deontological ethics in a categorical imperative of doing good for the sake of good regardless of its consequence (Kant’s Ethics). Considering the number of corporate scandals from Enron to WorldCom that helped slid this country in financial crisis, I am more inclined to believe that it is still better to be moral or ethical. Many people may disagree with my position as impractical that will make me finish last but I prefer to be moral and ethical. I can however rebut that as what we can see in the experience, the gains that were garnered with the lack of morals or ethics are short lived and temporary. We all see it on national TV where corporate executives were arrested for fraud. Criminals also lack morals and while they can get away with their crimes, it is again temporary and sooner or later, they too will be arrested. On a personal level, I believe nobody would disagree that we all want to deal with the people we trust. And earning trust requires a great deal of integrity and honesty such as keeping one’s words, not taking advantage of others etch all of which are the realms of morals and ethics. In the same vein, we also avoid dealing with people who

The Pain of Animals - Essay Example His position is that humans tend to rationalize their behavior and in doing so justify our mistreatment of certain groups of animals with no thought or concern for their inherent right to life; rather in our selfishness we too often have little regard for their well-being and quality of life. In order to substantiate his position he drew parallels through various instances of how humans either assume animals do not have emotions and can not feel pain or disregard the truth believing the human race is somehow entitled to do as they please in the name of science or sport. Drawing first on the experimentation of insects in the furthering of science Suzuki concedes that somehow that may be justifiable, but then further builds on the examples of experimentations on mice, rats, guinea pigs and other rodents to further both the medical and behavioral sciences and asks us to consider if this is the point at which the line should be drawn morally and ethically. In further defense of his position he talks about how humans are conditioned to have little disregard for the other animals with whom we share the planet. Man at one point, hunted and fished to sustain his own and his family's lives. Somewhere we have gone beyond that. We hunt and fish now not just for survival, but for sport, sacrificing the lives of animals just for our own amusement and pleasure not out of necessity.

Essay Example The waiters in their sparkling white uniforms were always cheerful; waving at us the moment we entered. They knew each person’s favourite flavour: if it was Mocha for the rest of my friends, they knew Rita and I loved it black. The soft lighting, the muted music and the relaxed atmosphere was enough to ease our jangled nerves after the long lectures. The waiters would not hover over us, expecting us to order snacks or accompaniments, but stand unobtrusively in the background, happy to oblige whenever one of us had enough pocket money to treat the rest to sandwiches. Yes, we were very frugal in those days, we had to be: after all, it was Mom-Dad’s money. The manager was a wonderful person, who remembered each of our names and would even help us earn some pocket money by working there in our free time. Yes, The Coffee House was a truly exotic place. Happy times leave happy memories. The happiest moment of my life was when sitting by the window table, I proposed to Rita over a cup of coffee. I had my own fears and doubts. I would have been shattered if she had refused. I knew she liked me, but was not sure if she liked me enough to spend the rest of her life with me. Both of us were just taking up our first jobs in the coming month and I felt that was the right time to ask her. The still remember the startled look in her eyes when in true a gentleman’s style, I fell on my knees and asked her if she would spend the rest of her life with me. With George Michael playing in the background, it felt just the right thing to do. She had a soft smile on her lips, a twinkle in her eyes and the setting sun was falling on her face, making her blush. Bashfully, she looked deep into my eyes and whispered â€Å"yes.† Shouts of â€Å"Whoa!†, â€Å"Bravo,† â€Å"Yippee† and catcalls filled the place. Our friend s were sitting across the room and were ecstatic too. The Manager made the moment

bpo management system Essay 1. Introduction 1.1 Purpose This document describes the high level design for the CHART/EORS Intranet Mapping Application and the CHART Internet Mapping Application. The purpose of this design is to show the high-level technical approach to meeting the requirements defined in system requirements specification. This serves to identify the architecture of the system and high-level interactions between major system components. 1.2 Objectives Identify and describe the software architecture for the system. Provide  high-level approaches to various technical challenges. Provide a guide for future development efforts, such as detailed design and coding. 1.3 Scope This high level design encompasses the approach for meeting the requirements as defined in the documents CHART/EORS Intranet Mapping System Requirement Specification and CHART Internet Mapping System Requirement Specification. 2. System Architecture 2.1 Overview The following diagram shows the system architecture used by CHART mapping applications.  The system design utilizes web based multi-tier system architecture. The data storage is managed at the data tier by the databases. The main business logics are hosted in the two applications in the web server. Because mapping is an area that there are many requirements related to client side interactions with the graphic content of the application, application logics are partitioned based on the most appropriate location to execute them. Some are located on the client browsers to provide instantaneous feedback to the user. The general system operation flow involves the following: 1. Data updates from various sources such as the CHART II CORBA events, EORS data inputs, device and event editing modules are stored in the databases. 2. When a mapping application receives a mapping request, it sends the image map generation request to the ArcIMS map server. The ArcIMS server retrieves the map data from the databases and creates a rendering of the map and saves it as a raster image file. The mapping application generates HTML pages embedded with the image and sends it to the browser client. 3. For the CHART Intranet mapping client, the application also generates the dynamic content in VML format, which encodes the device and event information in vector format. This enables the application to update the dynamic data without having to reload the whole map image. This avoids the heavy load on the map server when the application scales up. 4. When the images and VML  data arrives at the client browser, the client displays the map to the user. The user can interact with this data on the client. 2.2 SQL Server and ArcSDE ArcSDE from ESRI allows managing of geographic information in commercial databases such as SQL Server, Oracle, DB2 and Informix. ArcSDE provides functionalities to efficiently store and retrieve spatial information using spatial indexing mechanisms. ArcSDE provides a set of API and administrative utilities that help manage the spatial data storage. For the CHART mapping systems, the combination of ArcSDE and SQL Server manages the spatial information in the relational database. ArcSDE adds spatial functionalities without disrupting standard SQL database capabilities. 2.3 Map Server (ArcIMS) ArcIMS includes a few components that will play important roles in the CHART mapping application. The workhorse component that processes the data and generates maps is the spatial server. Managing the spatial servers is the ArcIMS Application Server, which monitors each spatial server’s activity and brokers map requests to the least busy spatial server. The detailed interaction of a map request is as the following: When the ASP.Net page receives a map request, it parses it and uses the ActiveX Connector object model to construct a map request. The connector then sends the map request in ArcXML format to the Application Server. The Application Server then finds the least busy spatial server and forwards the map request to it. The spatial server performs the query against the ArcSDE database, retrieves the data and renders them into a raster image file. The location of the file is then sent back to the connector and the ASP.Net page writes it back to the client as HTML page with the image embedded in it. 2.4 Web Server (IIS) .Net Framework and ASP.Net The web server hosts and publishes content to the client browser. In the case of the CHART mapping applications, most of the content is dynamic content generated by ASP.Net modules. When IIS recognizes a page being an ASP.Net module (an aspx extension), it passes the request to the .Net Framework to load the module and handle the request. The ASP.Net pages are then loaded into memory and executed. The .Net Framework provides many utilities such as garbage collection, tracing, just-in-time compilation that manages the execution of ASP.Net modules. The ASP.Net page modules are where the CHART mapping application logic is coded. The web server also provides security via the Secured Socket Layer (SSL), allowing interactions between the user’s browser and the web server to be encrypted when necessary. 2.5 Security 2.5.1 Network Level Security Network layer security will be managed by the network security configurations like firewall and RSA secure ID. 2.5.2 Secured Socket Layer (SSL) MDOT has a certificate server to provide digital certificates for the SSL configuration. The server name must remain consistent with the certificate. All links shall use the same server name, otherwise, if the server is referred using an IP address or a local server name, etc., the user will see an alert indicating the certificate is in-consistent with the resource. IIS supports the configuration of one folder in the web application requiring SSL while other portion does not. The session information remains consistent between SSL portion of the web site and the non-SSL portion. 2.5.3 Enterprise User Enters Read-Only View Many of the CHART mapping functionalities are for display and reviewing data, i.e. a read-only view. The design allows enterprise viewers and CHART users to access the read-only portion of the web site without having to input user name and password. This also enables CHART users to reach the viewing area without having to enter their login information again. When system receives a user request to enter the secured area, the system checks whether the current session has been authenticated. If not, system displays login screen. The user shall enter their CHART user name and password. Upon receipt of the user name and password, the system checks it  against the CHART II database’s user tables. If they are authenticated, the system stores the user information in the session. The session will be managed in the server until the configured timeout expires. All subsequent requests from the same user session will inherit the same authorization information for the user. 2.5.4 CHART User Enters Editing Area Other applications, like future versions of CHART II and CHART Lite, can launch the map editing URL via the HTTPS protocol. The user name and password can be sent via https request. The system verifies their authentication information against the CHART II user database using an OLEDB/ODBC connection. If the authentication information is correct, the system will store this information in the session. The user will be redirected to the map page. If the authentication is rejected, the user request will be redirected to the login screen to reenter the authentication information. Associating a CHART user with an op-center/default map view area: Based on CHART II R1B3 database design, users are not associated with an op-center; rather, the user specifies an op-center during logon. In order to display a default map view area based on an op-center, an external application launching the CHART mapping application will also need to pass in the operation center name to initialize the map to the associated extent. Passing user name and password in URL request: The mapping site shall have a module that verifies the user name and password, then forward the page to the map page, hence avoiding showing the password on URL address box. At the current time, without the full integration with CHART II and CHART Lite, the system will expect plain text user name and password. In the future, an encryption/decryption algorithms agreed between the systems can be added to achieve higher security. 2.5.5 EORS Security Currently, the EORS security has not been implemented. EORS functions will be hard-coded with security configuration. 3. Network Configuration The design above depicts CHART network configuration as the Internal network, a Demilitarization Zone (DMZ) network for hosting the web server and connecting out to the external Internet network. There will be two firewalls, one between the Internet and the DMZ network and another one between the DMZ network and the internal network. The map server and database servers are to be hosted in the internal network for maximum security. The initial configuration calls for two physical computers to host the map servers and database servers. In the future, if the system needs to scale up, additional physical servers can be added. The Intranet web server can optionally be hosted on the load-balanced virtual server too. 3.1.1 Map Server Load Balancing The design achieves load balancing by a combination of Windows 2000 Advanced Server Network Load Balancing (NLB) Service and the ArcIMS Application Server. The system utilizes two physical server computers. The two servers are configured with NLB. NLB works on the TCP/IP level. Any incoming traffic from web server to the virtual server IP address is load balanced between the two application servers by NLB. ArcIMS Application Server operates at the application level, monitoring each spatial server’s load and operation. When a spatial server is busy, it directs the map request to idling spatial server(s). Each physical map server hosts one ArcIMS Application Server and two ArcIMS Spatial Server instances. An application server failure forces NLB to direct new connections to the remaining application server. When the failed server is recovered, new client connections should once again be shared between the two servers. The two spatial server instances are â€Å"cross registered† to the application servers. As shown in the diagram, Spatial Server A1 and A2 are registered to Application Server B and A correspondingly. This arrangement ensures that when a spatial server is down, the application server can still  utilize the spatial server from the other server to serve the map request and the application server continue to function. Also, this configuration also allows ArcIMS to load balance at the Spatial Server level as opposed to just the network traffic level, which is what NLB provides. This configuration can withstand an Application Server failure, a Spatial Server failure, a simultaneous Application/Spatial Server failure or hardware failure of one of the physical map servers. Using two map servers with network load balancing should provide high-availability load balanced ArcIMS web site. 3.1.2 Database Load Balancing By running two SQL Server and ArcSDE instances with NLB to balance the load, the system can achieve high availability at the database server layer. The database servers are completely independent and share no hardware components. This type of availability is achievable with the standard edition of SQL Server. The two database servers are setup with Transactional replication. One of the two SQL Servers is configured as the publisher and the other one as a subscriber. All the data modification such as insert, delete and update will be performed on the publisher and changes are replicated to the subscriber. Transactional replication can provide very low latency to Subscribers. Subscribers receiving data using a push subscription usually receive changes from the Publisher within one minute or sooner, provided that the network link and adequate processing resources are available (latency of a few seconds can often be achieved). When the web server and map server requests use the virtual IP address on the load-balanced group of database servers, they are directed to the database server with the least amount of load. If one of the database servers goes down due to hardware failure, NLB detects that this server is down and no longer directs database requests to this machine. The remaining machine handles the database requests and apart from a slight drop in performance the users are unaware that a database server has failed. When the hardware is fixed the offending machine can be brought back online. One limitation exists for this design. It happens when the publisher database is down. In this situation the data updates cannot be committed until the publisher database comes back. But at the same time, all read access from the Internet and Intranet server could still be directed to the secondary server. In the case when the publisher data is going to be down for extended time period, system configuration need to allow system administrator to change the configuration so that the replica will serve as the main database. Compared with clustering solution, this system design provides the maximum database availability and performance benefit. The databases that need to be replicated would include: 1. Background map database. Background map data does not change often. A snapshot replication is sufficient for replicating data updates in one database to the other. 2. CHART/EORS Spatial Database CHART/EORS spatial database stores CHART and EORS device and event information with spatial data. They are dynamically updated throughout the day. Transactional replication will be setup to ensure that data change in one database gets replicated to the other one. 3. SDE metadata. In general, the system can continue to provide access of map and data to both the Internet and Intranet users in the case of failure of any one component in the system. The only exception is that when the publisher database is down, the new data cannot be updated into the system. Users will get delayed information. 3.1.3 DMZ Configuration CHART is currently implementing a Demilitarization Zone (DMZ) network to enhance the network security. This entails creating a separate network for the web server computer(s) and separating it from the internal network with a firewall. In an ideal world, the DMZ would have no physical connection to the internal network. This would require two separate map server setups to serve the  Internet and Intranet users. The recommended way to implement is to disallow any access from the DMZ to the internal network, but allow access from the internal network to the DMZ. In other words, allow out-bound connections. On each of the ArcIMS server computers, mount a network drive to a shared drive on the Web server. Each ArcIMS spatial server would write the output raster image files to the location on the web server to be delivered to the Internet client browsers. 4. Database Organization To reduce the dependency and operation interference between the spatial data and the attribute data, the EORS spatial database and CHART spatial database will be created as two SQL Server databases. To reduce the performance overhead when joining data between the spatial and attribute data, the EORS spatial database will reside on the same database server(s) as the EORS database. 5. Technical Challenges 5.1 Map Display Mechanism CHART Intranet mapping application requires that changes in event and device data be reflected on all map clients in a near-real-time fashion (within 5 seconds). To do so via the traditional raster map publishing mechanism will result in all clients retrieving updated map every 5 seconds or at least when event/device status update requires a new map to be generated. When there is large number of users of the system, it will result in a high map server load in a concentrated short time period. To resolve this issue, the project team reviewed various technical approaches and summarizes their advantages and disadvantages as the following: 5.1.1 Raster (JPEG, GIF or PNG) Image This is a popular approach that utilizes the basic image display functionality of web browsers. It utilizes the server processing power efficiently. The disadvantages are that the images have limited client side intelligence, leaving most of the computation concentrated on the server. It’s capability of handling large number of concurrent map requests is limited. Generally, one map server can support 4-8 requests per second. For  CHART’s situation, when an event changes status, if a new map image needs to be generated, it would be about 40 requests per second (200 users at 5 second update interval). Many servers will be required to support the load. With the license fee involved with using GIF format, we will not use GIF for map publishing. Compared with JPG format, PNG graphics do not have the â€Å"bleeding† effect inherent with the JPEG compression algorithm. With the map displaying lines rather than continuous tone images, it is much cleaner. PNG also results in a smaller file, which translates into faster download times for client. The only JPG advantage is server side image generation times. It is recommended to utilize PNG for the Intranet application to produce highest quality images for standardized IE browser while utilizing JPG for the Internet to allow for support of as many browsers as possible. Also, the reduction in image processing time should deliver better web image generation performance. 5.1.2 XML Based Vector Graphics 5.1.2.1 Vector Markup Language (VML) VML is a XML based W3C standard in describing vector graphics. Basically, it encodes the vector coordinates of points, lines and polygons in XML format. The support of VML is included in Internet Explorer 5.0 and later. There is no download needed to display VML encoded vector graphics. It also has built-in support for style sheet and scripting. This makes it possible to modify the display properties and positions of the vector graphics using the JavaScript on the client-side browser. Using this functionality, we can dynamically update the display of devices and events. 5.1.2.2 Scalable Vector Graphics (SVG) Scalable Vector Graphics is another XML-based W3C standard format for vector graphics. Compared with VML, it requires Java or ActiveX based plug-in to be displayed. Also, based on review of the plug-ins (SVG Viewer by Adobe), there is not as much support for scripting as for VML. 5.1.3 ArcIMS Java Viewer ArcIMS includes a Java Viewer, which provides a Java Applet that can be customized to a certain extent to display vector encoded GIS data on the client side. It requires a download to the client. The Java Viewer reads vector data from ArcIMS feature server encoded using an ESRI proprietary compression format, which makes it difficult to implement special features such as WSMS offsetted road networks because they need to be offset dynamically based on map scale. 5.1.4 MapObjects Java MapObjects Java from ESRI provides a set of Java-based objects for GIS functionalities. It has an extensive set of functionality that can satisfy the requirements. But, it requires a license fee of $100/seat, or comparable server-based licensing. It also requires a download to client machine to run it. 5.1.5 Summary Based on the research above, the project team recommends the following design: Use raster map for background map display (background data with SHA grid map are often large amount of data, suitable for server side processing) Use XML data format to transport the device and event data from server to browser client. Use JavaScript to create and update the VML vector data elements to display the dynamic layers including all the CHART/EORS devices and events. The diagram above illustrates the map display mechanism: 1. Map server reads the spatial data from background database and sends the published map image to the client browser to be displayed as background. 2. Device and event information is broadcasted from the CHART II system in the form of CORBA events. 3. CORBA event listener receives the event broadcast and saves the data into CHART spatial database. 4. CHART/EORS device and event data are published in XML format to the client. Client browser parses the XML into a XML Document Object Model (DOM) using the XML parser. 5. The client browser then iterate through the DOM tree structure and create corresponding VML elements based on the XML device and event data. The VML elements are displayed on the top of the background raster map image. 6. At a pre-configured interval, the browser client retrieves update of device and event data from the IIS server in XML format and update the VML display  based on the updated information. 5.2 Automated Refresh of Device and Event Data CHART/EORS device and event information needs to be updated at a pre-configured interval. They should be updated separate from the background map to reduce the load on the map server. The technical approach to achieve this will be to use a hidden frame to send the request to retrieve updated device and event data and receive the response. The response will package the data in XML file to be parsed into a document object model (DOM) and display the data on map. The request can be to retrieve all data or only retrieve data newer than last retrieval. When the new device/event is received and it requires changing the display of the device/events, the style assignment for the elements can be changed to update the device and event display.   The VML elements will be sent using real-world coordinates (Maryland State Plane 1983). After the data has been retrieved to the client side, the VML map layers can be dynamically projected using the â€Å"local coordinate space†. When user zooms or pan the map, the VML will be projected using the updated coordinates to fit the new map extent without going back to the server to retrieve new data set. 5.3 Inter-Frame Client Script Synchronization The map page has a few frames and the browser loads them asynchronously. Scripts in one frame may call scripts in another frame that may not have been loaded. The approach to resolve this is to add client-side exception handling and verification routine to ensure that the script is called always after the frame is loaded. 5.4 Assigning and Editing Event Location The dynamic nature of VML elements in the browser allows adding and modifying VML elements by scripting. When the user clicks or drags the mouse on the map, client-side script manages the transformation of screen coordinates and real-world map coordinates. The coordinates are sent back to the server’s secured URL where the information is extracted and saved to the database. 5.5 Scalability The CHART mapping application serves not only the Intranet users, but also Internet browser clients. During emergency situations, the load on both the Internet and Intranet servers could get extremely high. The system must be able to scale up to serve large amount of users. The technical approach to solve this issue involves two main facets. As described in the network configuration section, the system will employ network load balancing and allows adding additional hardware in the future. The system should also be able to utilize the caching feature of IIS and ASP.Net to scale up without significantly increase hardware investment. ASP.Net allows caching configuration for individual page modules, such as whether the page is cached and how long it is cached. After the application is deployed, these caching settings can be configured on the web pages. For example, if it is determined that the Internet mapping can be up to 3 seconds late, by setting caching time to 3 seconds, all requests from the Internet will receive a cached response without creating additional load on the map and database server. 5.6 Exception Management and Recovery CHART II keeps its clients updated via a push model using the CORBA Event Service. The Event Service does not guarantee delivery; therefore it is possible for event data to be lost/dropped (although in practice, this is rare). To account for this possibility, the CHART Web Event Listener will refresh its information about the status of devices and traffic events from CHART II at a configurable interval. Also, each time the Event Listener is started, it will retrieve all relevant data from CHART II. Thus, the update model becomes a push model with an occasional pull to be safe. This process will be used to recover from the following situations: 1. The Event Listener was down and did not receive new data from CHART II. 2. CHART II CORBA event(s) occasionally dropped while the Event Listener is up and running. Another likely scenario is that the CHART II server or service(s) restart. After a typical restart, the CORBA Event Service CORBA objects will be  recreated with the same characteristics allowing the Event Listener to continue to automatically receive CHART II CORBA events. As the CHART II services will not be processing events during this time, no events are likely to be missed. Therefore, the Event Listener does not need to do anything special to handle a CHART II server or service(s) restart. Sometimes CHART II maintenance will require that new (and different) Event Service CORBA objects be created. This might happen during a CHART II upgrade, for example. In this case, the Event Listener will need to be restarted so that it can pick up the new objects. Since this type of maintenance does not occur often and the Event Listener restarting is fast, the restart can be handled as part of the CHART II upgrade procedures. 5.7 Integration with ASP Code in EORS and CHART Web Application The CHART Intranet Mapping, replacing the existing EORS mapping application, will still be launched as a separate window by a URL string with a few parameters identifying the district, view type, etc. The impact on EORS web application should be limited to modifying the URL links. The current CHART Internet Mapping site uses â€Å"include† statement to include site navigation pages from upper level CHART web site’s pages. When upgrading Internet Mapping to ASP.Net, â€Å"include† statement is no longer used. Instead, a ServerXMLHTTP request can be formulated to request the text from the included ASP page and merge them into the mapping ASP.Net pages. The limitation of this implementation would be that the ASP.Net application couldn’t share the session and application variables from the ASP application. Currently, there are only a couple of them, such as database connection string. The ASP.Net mapping application will maintain a separate set of application variables. 6. User Interface Design 6.1 Intranet Map Site User Interface Design Here following is a high-level frame structure for the Intranet mapping site: 1. AppFrame is the highest-level frame that includes all the child frames. On the top of the page, there will be the title frame, which will host the  CHART icon. Also inside the title frame will be a group of tabs, such as Traffic, Roadway Weather, Message Sign, etc. 2. ToolsFrame hosts the map navigation and other map related tools. The ToolsFrame will also host menu system that allows the user to bring up data and other detailed information. 3. HiddenFrame will be used to submit and receive information from the server. 4. ContentFrame is further divided to a map frame on the left and a data frame on the right. The user shall be able rearrange the frame boundary to give more space to the map or data area. Data frame will display data as well as legend, layer control and other items when needed. 5. PromptFrame will display the current tool selected and instructions for user activities. Here is a screen shot of the preliminary user interface design: 6.2 Internet Map Site User Interface The overall CHART Internet mapping web site design will stay the same as current web site. The site will stay as part of the overall CHART web site by including the CHART navigation menus into the site. The site will not be using frames; instead, all elements will be laid out as HTML tables. 7. References 1. CHART/EORS Intranet Mapping System Requirement Specification 2.

Uses Of Computer Network Data Transmission Modes Information Technology Essay

Uses Of Computer Network Data Transmission Modes Information Technology Essay We all are aware with some sorts of communication in our day to day life. For communication of information and messages we use telephone and postal communication systems. Similarly data and information from one computer system can be transmitted to other systems across geographical areas. Thus data transmission is the movement of information using some standard methods. These methods include electrical signals carried along a conductor, optical signals along an optical fibers and electromagnetic areas. Suppose a Managing Director of a company has to write several letters to various employees . First he has to use his PC and Word Processing package to prepare his letter. If the PC is connected to all the employees PCs through networking, he can send the letters to all the employees within minutes. Thus irrespective of geographical areas, if PCs are connected through communication channel, the data and information, computer files and any other program can be transmitted to other computer systems within seconds. The modern form of communication technologies like e-mail and Internet is possible only because of computer networking. Computers are powerful tools. When they are connected in a network, they become even more powerful because the functions and tools that each computer provides can be shared with other computers. Networks exist for one major reason: to share information and resources. Networks can be very simple, such as a small group of computers that share information, or they can be very complex, covering large geographical areas. Regardless of the type of network, a certain amount of maintenance is always required. Because each network is different and probably utilizes many various technologies, it is important to understand the fundamentals of networking and how networking components interact. In the computer world, the term network describes two or more connected computers that can share resources such as data, a printer, an Internet connection, applications, or a combination of these. Prior to the widespread networking that led to the Internet, most communication networks were limited by their nature to only allow communications between the stations on the network. Some networks had gateways or bridges between them, but these bridges were often limited or built specifically for a single use. One common computer networking method was based on the central mainframe method, simply allowing its terminals to be connected via long leased lines. This method was used in the 1950s by Project RAND to support researchers such as Herbert Simon, in Pittsburgh, Pennsylvania, when collaborating across the continent with researchers in Santa Monica, California, on automated theorem proving and artificial intelligence. At the core of the networking problem lay the issue of connecting separate physical networks to form one logical network. During the 1960s, several groups worked on and implemented packet switching. Donald Davies, Paul Baran and Leonard Kleinrock are credited with t he simultaneous invention. The notion that the Internet was developed to survive a nuclear attack has its roots in the early theories developed by RAND. Barans research had approached packet switching from studies of decentralisation to avoid combat damage compromising the entire network. By mid-1968, Taylor had prepared a complete plan for a computer network, and, after ARPAs approval, a Request for Quotation (RFQ) was sent to 140 potential bidders. Most computer science companies regarded the ARPA-Taylor proposal as outlandish, and only twelve submitted bids to build the network; of the twelve, ARPA regarded only four as top-rank contractors. At years end, ARPA considered only two contractors, and awarded the contract to build the network to BBN techologies on 7 April 1969. The initial, seven-man BBN team were much aided by the technical specificity of their response to the ARPA RFQ and thus quickly produced the first working computers. The BBN-proposed network closely followed Taylors ARPA plan: a network composed of small computers called Interface message processor (IMPs), that functioned as gateways (today routers) interconnecting local resources. At each site, the IMPs performed store-and-forward packet switching functions, and were interconnected with modems that were connected to leased line, initially running at 50 kilobit/second. The host computers were connected to the IMPs via custom serial communication interfaces. The system, including the hardware and the packet switching software, was designed and installed in nine months. The first-generation IMPs were initially built by BBN Technologies using a rough computer version of the Honeywell DDP-516 computer configured with 24 Kilobyte of expandable core memory, and a 16-channel Direct Multiplex Control (DMC) Direct Memory Access unit. The DMC established custom interfaces with each of the host computers and modems. In addition to the front-panel lamps, the DDP-516 computer also features a special set of 24 indicator-lamps showing the status of the IMP communication channels. Each IMP could support up to four local hosts, and could communicate with up to six remote IMPs via leased lines. 1.2 ARPANET The Advanced Research Projects Agency Network (ARPANET), was the worlds first operational Packet Switching network and the core network of a set that came to compose the global Internet. The network was created by a small research team at the Massachusettas Institute of Technology and the Defense Advanced Research Projects Agency (DARPA) of the Defence Department of United States. The packet switching of the ARPANET was based on designs by Lawrence Roberts of the Lincoln Laboratories. Packet switching is the dominant basis for data communications worldwide and it was a new concept at the time of the conception of the ARPANET. Data communications had been based on the idea of Circuit Switching, as in the traditional telephone circuit, wherein a telephone call reserves a dedicated circuit for the duration of the communication session and communication is possible only between the two parties interconnected. With packet switching, a data system could use one communications link to communicate with more than one machine by collecting data into Datagram and transmit these as Packet onto the attached network link, whenever the link is not in use. Thus, not only could the link be shared, much as a single PostBox can be used to post letters to different destinations, but each packet could be routed independently of other packets. 1.3 SNA Systems Network Architecture (SNA) is IBMs proprietary Computer Network architecture created in 1974. It is a complete Protocol Stack for interconnecting Computer and their resources. SNA describes the protocol and is, in itself, not actually a program. The implementation of SNA takes the form of various communications packages, most notably Virtual telecommunications access method (VTAM) which is the mainframe package for SNA communications. SNA is still used extensively in banks and other financial transaction networks, as well as in many government agencies. While IBM is still providing support for SNA, one of the primary pieces of hardware, the IBM 3745/3746 communications controller has been withdrawn from marketing by the IBM Corporation. However, there are an estimated 20,000 of these controllers installed and IBM continues to provide hardware maintenance service and micro code features to support users. A strong market of smaller companies continues to provide the 3745/3746, features, parts and service. VTAM is also supported by IBM, as is the IBM Network Control Program (NCP) required by the 3745/3746 controllers. IBM in the mid-1970s saw itself mainly as a hardware vendor and hence all its innovations in that period aimed to increase hardware sales. SNAs objective was to reduce the costs of operating large numbers of terminals and thus induce customers to develop or expand Interactive terminal based-systems as opposed to Batch Processing systems. An expansion of interactive terminal based-systems would increase sales of terminals and more importantly of mainframe computers and peripherals partly because of the simple increase in the volume of work done by the systems and partly because interactive processing requires more computing power per transaction than batch processing. Hence SNA aimed to reduce the main non-computer costs and other difficulties in operating large networks using earlier communications protocols. The difficulties included: A communications line could not be shared by terminals whose users wished to use different types of application, for example one which ran under the control of CICS and another which ran under Time Sharing Option. Often a communications line could not be shared by terminals of different types, as they used different vernacular of the existing communications protocols. Up to the early 1970s, computer components were so expensive and bulky that it was not feasible to include all-purpose communications interface cards in terminals. Every type of terminal had a Hardwired Control communications card which supported only the operation of one type of terminal without compatibility with other types of terminals on the same line. The protocols which the primitive communications cards could handle were not efficient. Each communications line used more time transmitting data than modern lines do. Telecommunications lines at the time were of much lower quality. For example, it was almost impossible to run a dial-up line at more than 300 bits per second because of the overwhelming error rate, as comparing with 56,000 bits per second today on dial-up lines; and in the early 1970s few leased lines were run at more than 2400 bits per second (these low speeds are a consequence of Shannon-Hartly Theorm in a relatively low-technology environment). Telecommunications companies had little incentive to improve line quality or reduce costs, because at the time they were mostly monopolies and sometimes state-owned. As a result running a large number of terminals required a lot more communications lines than the number required today, especially if different types of terminals needed to be supported, or the users wanted to use different types of applications (.e.g. under CICS or TSO) from the same location. In purely financial terms SNAs objectives were to increase customers spending on terminal-based systems and at the same time to increase IBMs share of that spending, mainly at the expense of the telecommunications companies. SNA also aimed to overcome a limitation of the architecture which IBMs System/370 mainframes inherited from System/360. Each CPU could connect to at most 16 channels (devices which acted as controllers for peripherals such as tape and disk drives, printers, card-readers) and each channel could handle up to 16 peripherals i.e. there was maximum of 256 peripherals per CPU. At the time when SNA was designed, each communications line counted as a peripheral. Thus the number of terminals with which powerful mainframe could otherwise communicate is severely limited. SNA removed link control from the application program and placed it in the NCP. This had the following advantages and disadvantages: Advantages Localization of problems in the telecommunications network was easier because a relatively small amount of software actually dealt with communication links. There was a single error reporting system. Adding communication capability to an application program was much easier because the formidable area of link control software that typically requires interrupt processors and software timers was relegated to system software and NCP. With the advent of APPN, routing functionality was the responsibility of the computer as opposed to the router (as with TCP/IP networks). Each computer maintained a list of Nodes that defined the forwarding mechanisms. A centralized node type known as a Network Node maintained Global tables of all other node types. APPN stopped the need to maintain APPC routing tables that explicitly defined endpoint to endpoint connectivity. APPN sessions would route to endpoints through other allowed node types until it found the destination. This was similar to the way that TCP/IP routers function today. Disadvantages Connection to non-SNA networks was difficult. An application which needed access to some communication scheme, which was not supported in the current version of SNA, faced obstacles. Before IBM included X.25 support (NPSI) in SNA, connecting to an X.25 network would have been awkward. Conversion between X.25 and SNA protocols could have been provided either by NCP software modifications or by an external protocol converter. A sheaf of alternate pathways between every pair of nodes in a network had to be predesigned and stored centrally. Choice among these pathways by SNA was rigid and did not take advantage of current link loads for optimum speed. SNA network installation and maintenance are complicated and SNA network products are (or were) expensive. Attempts to reduce SNA network complexity by adding IBM Advanced Peer-to-Peer Networking functionality were not really successful, if only because the migration from traditional SNA to SNA/APPN was very complex, without providing much additional value, at least initially. The design of SNA was in the era when the concept of layered communication was not fully adopted by the computer industry. Applications, Database and communication functions were come together into the same protocol or product, to make it difficult to maintain or manage. That was very common for the products created in that time. Even after TCP/IP was fully developed, X Window system was designed with the same model where communication protocols were embedded into graphic display application. SNAs connection based architecture invoked huge state machine logic to keep track of everything. APPN added a new dimension to state logic with its concept of differing node types. While it was solid when everything was running correctly, there was still a need for manual intervention. Simple things like watching the Control Point sessions had to be done manually. APPN wasnt without issues; in the early days many shops abandoned it due to issues found in APPN support. Over time, however, many of the issues were worked out but not before the advent of the Web Browser which was the beginning of the end for SNA. 1.4 X.25 and public access Following on from DARPAs research, packet switching networks were developed by the International Telecommunication Union (ITU) in the form of X.25 networks. In 1974, X.25 formed the basis for the SERCnet network between British academic and research sites, which would later become JANET. The initial ITU Standard on X.25 was approved in March 1976. The British Post Office, Western Union International and Tymnet collaborated to create the first international packet switched network, referred to as the International Packet Switched Service (IPSS), in 1978. This network grew from Europe and the US to cover Canada, Hong Kong and Australia by 1981. By the 1990s it provided a worldwide networking infrastructure. Unlike ARPAnet, X.25 was also commonly available for business use. X.25 would be used for the first dial-in public access networks, such as Compuserve and Tymnet. In 1979, CompuServe became the first service to offer electronic mail capabilities and technical support to personal computer users. The company broke new ground again in 1980 as the first to offer real-time chat with its CB Simulator. There were also the America Online (AOL) and Prodigy dial in networks and many bulletin board system (BBS) networks such as The WELL and FidoNet. FidoNet in particular was popular amongst hobbyist computer users, many of them hackers and radio amateurs. 1.5 UUCP In 1979, two students at Duke University, Tom Truscott and Jim Ellis, came up with the idea of using simple Bourne shell scripts to transfer news and messages on a serial line with nearby University of North Carolina at Chapel Hill. Following public release of the software, the mesh of UUCP hosts forwarding on the Usenet news rapidly expanded. UUCPnet, as it would later be named, also created gateways and links between FidoNet and dial-up BBS hosts. UUCP networks spread quickly due to the lower costs involved, and ability to use existing leased lines, X.25 links or even ARPANET connections. By 1983 the number of UUCP hosts had grown to 550, nearly doubling to 940 in 1984 1.6 Uses of Computer Networks Computer networks have many uses in present life. However, the usage goes on increasing from day to day, More and more people use networks for their corresponding applications and thus increasing the area of usage. However, we categorize the usage of computer network as follows Resource Sharing: The global here is to make all programs equipment and especially data available to anyone on the network without regard to the physical location of the resource and the user. High Reliability: Always all the files could be replicated on one or more machine. So if one of them is unavailable the other copies could be used for the reference. Saving money: Small computers have a much better price / performance ratio than larger ones .Mainframes are roughly a factor of ten faster than personal computers, but they cost Thousand times more. This imbalance has caused many system designers to build systems Consisting of personal computers, with data kept on more than one machine Communication medium: A computer network can provide a powerful communication medium among widely separated employees. Using a network, it is easy for two or more people who live far apart to write a report together. When one person makes a change, the other can easily look into that and convey his acceptance. Access to remote information: Many People, pay their bills, manage their accounts, Book tickets, electronically. Home shopping has also become popular, with the ability to inspect the on-line catalogs of thousands of companies. There are also cases where people are able to get information electronically. Email: Electronic Mail or E-Mail is an application through which a person can communicate With another person present anywhere. E Mail is used today by millions of people and they Can send audio or video in addition to text. WWW (World Wide Web) : A main application that falls into the application category is access to information systems like the current World wide Web, which contains information about arts, books, business, cooking, government, health so on. 1.7. Data Transmission Modes: Data communication circuits can be configured in a huge number of arrangements depending on the specifics of the circuit, such as how many stations are on the circuit, type of transmission facility, distance between the stations, how many users at each station and so on. Data communication circuits can however be classified as either two point or multipoint . A two-point configuration involves only two stations, whereas a multipoint configuration involves more than two stations. Regardless of configuration, each station can have one or more computers, computer terminals or workstations. A two point circuit involves the transfer of digital information from a mainframe computer and a personal computer, two mainframe computers, two personal computers or two data communication networks. A multipoint network is generally used to interconnect a single mainframe computer to many personal computers or to interconnect many personal computers. Coming to transmission modes, there are four modes of transmission for data communication circuits namely- 1. Simplex 2. Half-Duplex 3. Full Duplex Simplex In a simplex mode, the transmission of data is always unidirectional. Information will be sent always only in one direction Simplex lines are also called receive-only, transmit-only, or one-way-only lines. A best example of simplex mode is Radio and Television broadcasts. Fig. 1.1 Simplex Communication Half-Duplex In the half-duplex mode, data transmission is possible in both the directions but not at the same time. When one device is sending, the other can only receive, and vice-versa. These communication lines are also called two-way-alternate or either-way lines. Fig. 1.2 Half Duplex Communication Full Duplex In the full-duplex mode, the transmissions are possible in both directions simultaneous, but they must be between the same two stations. Full-duplex lines are also called two-way simultaneous duplex or both-way lines. A good example for full-duplex transmission is a telephone Fig. 1.3 Full Duplex Communication Types of Data Transmission Modes There are two types of data transmission modes. These are: Parallel Transmission Serial Transmission 1. Parallel Transmission In parallel transmission, bits of data flow concurrently through separate communication lines. Parallel transmission is shown in figure below. The automobile traffic on a multi-lane highway is an example of parallel transmission. Inside the computer binary data flows from one unit to another using parallel mode. If the computer uses 32-bk internal structure, all the 32-bits of data are transferred simultaneously on 32-lane connections. Similarly, parallel transmission is commonly used to transfer data from computer to printer. The printer is connected to the parallel port of computer and parallel cable that has many wires is used to connect the printer to computer. It is very fast data transmission mode. 2. Serial Transmission In serial data transmission, bits of data flow in sequential order through single communication line. Serial dat transmission is shown in figure below. The flow of traffic on one-lane residential street is an example of serial data transmission mode. Serial transmission is typically slower than parallel transmission, because data is sent sequentially in a bit-by-bit fashion. Serial mouse uses serial transmission mode in computer. Synchronous Asynchronous Transmissions Synchronous Transmission In synchronous transmission, large volumes of information can be transmitted at a time. In this type of transmission, data is transmitted block-by-block or word-byword simultaneously. Each block may contain several bytes of data. In synchronous transmission, a special communication device known as synchronized clock is required to schedule the transmission of information. This special communication device or equipment is expensive. Asynchronous Transmission In asynchronous transmission, data is transmitted one byte at a time. This type of transmission is most commonly used by microcomputers. The data is transmitted character-by-character as the user types it on a keyboard. An asynchronous line that is idle (not being used) is identified with a value 1, also known as Mark state. This value is used by the communication devices to find whether the line is idle or disconnected. When a character (or byte) is about to be transmitted, a start bit is sent. A start bit has a value of 0, also called a space state. Thus, when the line switches from a value of 1 to a value of 0, the receiver is alerted that a character is coming.

Incongruities Within The Philosophy Of Socrates :: essays research papers

Incongruities Within the Philosophy of Socrates   Ã‚  Ã‚  Ã‚  Ã‚  There appears to be an unnatural and unfounded fascination with the alleged â€Å"works† of Socrates. Perhaps that it is simply that the absolutist ideals of philosophers such as Plato and Socrates do not appeal to the post-modern, politically correct, wishy washy, materialistic reader. It is more likely, however, that the problems posed by the philosophy itself and its surrounding circumstances outweigh the insight and philosophical ingenuity.   Ã‚  Ã‚  Ã‚  Ã‚  The world of forms is a creation in the mind of Socrates that contains within it multiple ironies. Socrates claims to be closer to the real and Truth than any other man in the history of the world. Socrates claims that he has achieved this level of higher understanding through a lifetime in passionate pursuit of his personal ideal†¦Truth. Yet this Greek philosoph is the sole propounder of the viewpoint, which holds that there is one true example of all objects (a singular definition and model of a table or a chair).   Ã‚  Ã‚  Ã‚  Ã‚  The craftsman and idea smith of new theories cannot claim them as fact, for in similar situations, great thinkers have claimed that the world is flat, that the planets, the sun and all the heavens revolve around the Earth, and that Asia and the East Indies lie only 1100 miles west of the European continent. All of these conceptions of reality were later proved to be false, and, indeed, now seem ridiculous to the modern scholar. Anyone who is even slightly educated knows that this planet (and, in fact, all known planets) is spherical; the Earth and the rest of the planets in this solar system revolve around the sun, which is, incidentally, a relatively minor star; and there is an entire continent between Europe and Columbus’s Asian objective, the continent, in fact, on which we live. The theories proposed by Socrates are similar. It is difficult for the modern reader to believe that there is one quintessential automobile or television set.   Ã‚  Ã‚  Ã‚  Ã‚  Just as there is no singular true representation of an object, these articles do not even necessarily have a solitary purpose. The world’s most perfect stick, the one that exists in the world of forms, also makes a dandy measuring device. According to Socrates, there is only one illustration of each object and one and only one definition of the article’s purpose. However, it cannot be denied that a stick can also be used to measure, and a flashlight could also be used as a weapon.

Shakespeare Theme Essay

A. P. Literature How does Shakespeare express theme through language? Shakespeare, an extraordinary writer, uses many literary techniques which prove his mastery of English. His most fascinating technique however, is displaying theme through language. In his play â€Å"Hamlet†, Shakespeare uses language to address existential dilemma, truth, and death. These themes significantly shape â€Å"Hamlet† into the masterpiece it is. In his play, Shakespeare expresses existential dilemma through Hamlet. Hamlet’s life so far has gone roughly in a negative direction.His father, the King of Hamlet, has passed away; and disappointingly, Hamlet comes back to a crowd that is busy acknowledging the new king, Claudius, and is forgetting about the death of his father. Shakespeare uses language to express theme through Hamlet’s soliloquy, â€Å"To be, or not to be†. In his soliloquy, Hamlet asks himself whether he should kill himself, or keep going. Hamlet illustrate s the strain that many people feel at one point or another, the world is just too much. Another theme that Shakespeare expresses in his play through language is truth. For a â€Å"madman† such as Hamlet, he is pretty intent on getting his facts straight.Hamlet wants to be sure Claudius is his father’s murderer before he takes any drastic action. After being enraged by his father’s speech, Hamlet tries to find out the truth. In Act 3, Scene 2, Hamlet stages a play called â€Å"Mousetrap†, which portrays the death scene his father described. During that scene, Hamlet intends to watch Claudius to see if he expresses guilt. Through language, Shakespeare shows truth. Hamlet goes to great measures of finding out what is true; expressing a view that believing if another is honest is a matter of great trust, or great naivete. Lastly, Shakespeare expresses through language the theme of death.In Shakespeare’s play, Hamlet encounters death through his fatherà ¢â‚¬â„¢s ghost, and in Polonius’s and Ophelia’s demises. These run ins prompt Hamlet to look at death through different angles. For instance, the ghost of his father causes Hamlet to think about the spiritual aftermath of death. After Polonius’s death in Act 4, Hamlet compares death to the â€Å"Worm that ate the king’s corpse, that might be used to catch a fish to feed a beggar†. In other words, Shakespeare comments that death is a great equalizer, or as a stepping stone to truth away from an ambiguous dishonest world.Hamlet is a play that strongly represents the themes of the world through the language of art. Shakespeare enforces his views of the world through events that can be decoded into many messages. With just a few characters and occurrences, Shakespeare is able to illustrate themes such as existential dilemma, truth, and death. Through its many ingenious themes, â€Å"Hamlet† can be considered an outline of the treacherous world w e live in. If you take anything for granted, or trust everything you hear, your path will become a difficult one.
