Civil Peace

Civil Peace Chinua Achebe The short story â€Å"Civil Peace† by Chinua Achebe is about a man named Jonathan Iwegbu, his wife Maria and his three surviving children. Chinua Achebe’s emphasis in his short story is how Jonathan and his family are trying to get on with their lives after the Civil War in Nigeria. Moreover, there is a phrase that Jonathan says several times through his story, â€Å"nothing puzzles God†. What does Jonathan means when he says this?The story starts off with Jonathan realizing how lucky he is to have survived the war along with his wife and three of his four children, one of his sons did not survive. He also mentions that his old bicycle which he had buried in the ground a year earlier just needed a little greasing and was able to be used again. This is also where Jonathan first uses the phrase â€Å"Nothing puzzles God†, (page 29). I think that in this part of the story Jonathan means that although his bicycle had been buried in th e ground for a year all that it needed to work again was a little oil.Most people may have thought that the bicycle would have been no good or puzzled by the fact that it worked, but God knew that it would be okay, so Jonathan places his faith in God, â€Å"Nothing puzzles God†. Jonathan immediately put his bicycle to use as a taxi to earn money. He then mentions that he makes the journey to Enugu and when he arrives he finds another miracle. His little house is still standing, â€Å"he discovers that miraculously his own modest home is intact†, Dameron Charles, â€Å"Chinua Achebe†, A Reader's Companion to the Short Story in English, paragraph 15.He again uses the phrase â€Å"nothing puzzles God†. Jonathan talks about the fact that just two houses away a huge concrete structure is no longer there, but his tiny little house has survived. As this point, I think Jonathan means that despite the war and hardship a small house withstood the effects of the war and Jonathan and his family had a place to return to. Jonathan after fixing his home opens a palm-wine bar for soldiers and people who had a lot of money. He opens this bar rather than going back to work as a miner. Jonathan talks of receiving twenty pounds from the treasury which he eceived for turning in rebel money and how he felt like it was Christmas because he had so much money. He attracts the attention of thieves who show up at his home that night to steal the money. Jonathan explains how he is usually a heavy sleeper but on this night he hears ever noise. He finally falls asleep and is awakened by knocking at the door. Jonathan and his wife scream for the police and for their neighbors but no one comes to help them. The thieves want one hundred pounds, but Jonathan tells them that he only has the twenty pounds that he had received from the treasury.Jonathan agrees to hand over the twenty pounds and the thieves leave. When Jonathan tells people of the robbery the next morni ng, he again uses the phrase â€Å"Nothing puzzles God†, (page 34). I believe that Jonathan means that with everything that has happened, the war, his son’s death, his bicycle being recovered, his house still standing, and finally the robbery that God has a plan for everything and although we may not understand what that plan is God does and therefore nothing puzzles God.He is a humble man, â€Å"He is a modern, and modest, hero, a rural counterpoint to the doomed Gladys†. Dameron Charles, â€Å"Chinua Achebe†, A Reader's Companion to the Short Story in English, paragraph 15. Chinua Achebe is aware of Jonathan’s feelings and he knows about his suffering and of his family members. However, the writer mentioned that Jonathan has a strong faith of God. Moreover, Jonathan always keeps his optimistic view of life and that is very important for all readers.

Obesity: Logic and Marion Nestle

â€Å"Obesity: Who is Responsible for Our Weight? † In the essay, â€Å"Obesity: Who Is Responsible for Our Weight? † Radley Balko explains his argument on obesity; we are responsible for what we eat. Overall, the strengths were clear and persuading in this essay. One strength in his essay was his main point, we are responsible for our own weight. He explains that we are in control of what we consume, and the government should not be responsible for that. This engages the reader to think, should we really blame the government, or is ourselves to blame. This main point validates all his reasoning.Another strength is his ability to explain why government intervention is irrelevant to obesity. For example, he mentions that Oakland Mayor Jerry Brown is conducting to have a Fat Tax on high calorie food, where food restaurants must list their fat, calories, etc. on each meal. And instead they should be promoting personal-sense awareness. Overall this essay had more weaknesses than strengths. Though his side of the argument is completely true, his reasoning weren’t clearly detailed. For example, Radley Balko only targeted the government’s intervention on obesity.But what should have followed that is the food industry businesses that allow this, not just the government. Not only did he lack detail, but also he didn’t consider the point of genetics. Some Americans do not become obese by choice, but by genetics. Those who are affected by genetics may be very conscience of what they eat, but it still does no justice because of their genes. This weakened his essay. Another weakness is that he focuses too much on the government’s intervention on obesity; instead he should have listed more reasons to why obesity is a personal problem.Taken as a whole, the essay was very short, and took a while to get to the point. â€Å"Are You Responsible for Your Own Weight? † I found this to be a very strong, interesting argumentative essay by Kelly Brownell and Marion Nestle. One strength relates to the fulfillment on attention grabbing in their opening sentence. Brownell and Nestle reminds us that the food industry is like any other business: they must grow. This makes a valid point, and grabs the readers attentions which leads to wanting to read more.Mentioning the counter-argument that obesity is a personal responsibility is also a strength. This tells the reader that she is understanding to the opposing argument, while making hers very clear. Another strength is the fact that gives several examples why personal responsibility isn’t to blame which includes; obesity is growing year after year, it’s human biology for humans to be attracted to good food with high calories, the default approach of promotion of eating better and exercising more has failed for multiple years, and how personal responsibility is a trap.Not only did they have multiple examples, they had clear reasoning for each example, which proves they thought out their argument on obesity. Although this was a very strong, convincing essay, there were a couple of weaknesses. The first weakness is the unawareness of government’s real role in business. In America, our policy towards business relies strictly on the concept of Laissez Faire. Laissez Faire means allowing industry to be free from state intervention, especially restrictions in the form of tariffs and government monopolies.This is a very known concept to many Americans, and this weakens her argument. Another weakness is Brownell and Nestle mentioning they’re attentive to personal responsibility, but didn’t clearly give any reasoning to that. Overall, they essay was very well structured and barely had any weaknesses. The essay â€Å"Are You Responsible for Your Own Weight? † gives a more persuading argument. First of all this essay was clearly structured, which made it easier to read. The first essay was not as easy to read, and not as structured.Brownell and Nestle listed their reasoning, which made their points clear reassuring no confusion. Where as to Balko, there were barely any explained points in his essay, which made it hard to follow. Also, Brownell and Nestle are much more persuasive. They provided clear explained examples of why we are not the only ones responsible for obesity while Balko had little to none examples of why we are responsible. Altogether, Marion Nestle and Kelly Brownell provided a more effective argument on obesity and whose responsible for it than Radley Balko.

Texting vs. Txting

Texting vs. Txting We live in a society where education and experience are some of the most valued characteristics to acquiring a well-paid job in the vast job market. We no longer live in the past where a high school degree was enough to land you a managerial position in a corporate company, and our expectations for education do not stop at an early accomplishment of an Associate’s Degree. We need, and presume for more. Starting out with a minute understanding of the world, we have evolved and grown to comprehend not only the physics of nature, but we are now capable of predicting what will happen next in our daily lives.Over the last centuries we have developed numerous languages and techniques to be able to thoroughly communicate and express our feeling to one another. Language is a method for communication and should not be taken for anything higher. Why can’t we simplify the language to our benefits to promote a more effective, and efficient system of communication ? Currently texting is defined as a â€Å"textese,† â€Å"slanguage,† or a â€Å"digital virus† (Crystal 335). Texting is a source of communication, promoting positive impacts on learning, time consumption, and social interactions.Texting consists of numbers, letters, and signs which allow us to condense long and challenging expressions into more efficiently read words on a keyboard. Texting is used to condense elongated words into simpler more easily typed words. The word â€Å"message† can be converted to simpler more efficient term â€Å"msg. † Before you break any rules of the English language, you first need to understand the linguistic rules of the correct language to be able to text appropriately.Texting helps the users to comprehend the language more than ever before as David Crystal states, â€Å"The latest studies ( from a team at Coventry University) have found strong positive links between the use of texting language and the skills und erlying success in standard English in pre-teenage children†(Crystal 345). In a sense the â€Å"art† of texting is beneficial not only to conserve time, but to expand on the knowledge of vocabulary and grammatical understanding of the English language.Time has become a very treasured and valuable aspect in our daily lives. We sleep less, walk faster, and work harder in order to complete more tasks and to be able to live our lives to the fullest. Texting is a part of that same scheme of things; shaving lost time spelling full words, and promoting efficiency in our daily lives. Although efficiency is a positive aspect on texting, some would say otherwise such as Lynne Truss states, â€Å"I have a ‘zero tolerance approach’ to grammar mistakes that make people look stupid. The use of texting must contain an appropriate time and place to be used, as this example explains that inappropriate uses of texting would cost you your job. An example of a way that textin g promotes efficiency is that of someone that works in an office environment, where employees can do desk work and still be able to speak to their acquaintances without having to take a break and walk outside to speak about their matter. Texting promotes a broader band of social interactions between family, friends, and co-workers.Texting is a source of communication that does not require your full attention as talking on the phone would. Texting also promotes a larger and wider range of conversations to be discussed with an array of outcomes and results to be conjured upon over time. This creative and complex method for communication allows for a longer and more interesting approach to communication versus speaking to someone face-to-face or on the phone. This strategy of messaging is an ultimately easier and more relaxed approach to communication on the go.Cellphone messaging can lead to more outcomes, as well as more ideas to be explored. Texting is a broad source for learning, e fficiency, and social exploration. Although texting has claimed a bad reputation over the years, such as texting and driving, we need to look past the bad and towards the future of texting. Texting is a skill and a privilege containing rules and expectations to be used while texting. Today, we have a new and preferred way to communicate for the young and the old, and the trend continues to grow.Texting is a new system of communication and we should not label it as a disruption, but rather call it a â€Å"language in evolution† (Crystal 345).

Does Proper Education On Pros And Cons Of Neonatal Circumcision Help Research Paper

Does Proper Education On Pros And Cons Of Neonatal Circumcision Help Parents Make A Better Decision On The Procedure - Research Paper Example In the United States, more than half of newborn male babies are circumcised although the numbers have been dwindling in current times (Androus, 2011). Notably, there are no religious or medical reasons compelling the parents who circumcise their male babies to do so, implying these circumcisions are nonmedical and non-religious. Whether there should be educational programs guide parents on neonatal circumcision and its benefits and cons has been the subject of heated debates in the health sector and the public sphere for quite some time pitting the opponents and the proponents of education on neonatal circumcision against each other. While some support neonatal circumcision as good for newborns’ health, others oppose it, making parents even more confused about the procedure. They hence make decisions on neonatal circumcision based on what their friends and relatives feel, think, and say. That is, their decision is not influenced by well-informed expert opinion; rather, it is t he emotionality with which their friends and relatives advise them that determines their decision (Aston, 2002). For parents to have a good understanding and perception of neonatal circumcision and its pros and cons and to make the right decisions, education and other awareness programs are highly recommended (Aston, 2002). That neonatal circumcision has become a rather controversial and fiercely debated health and social issue is evident in the many literary works that research and publish on neonatal circumcision. Literature Review A quick review of literatures available on neonatal circumcision and circumcision in general reveals that both the pros and cons of neonatal circumcision have been covered in equal measures. Specifically, a lot of literatures covering the pros and cons of neonatal circumcision touch on its health care implications. There are several advantages newborn male babies and their parents could derive from neonatal circumcision. First, neonatal circumcision is an easier procedure compared to later life circumcision since the circumcised penis is allegedly easier to care for in early stages of growth and development. Second, circumcised babies report less incidences of urinary tract infections compared to uncircumcised children. The other general benefits of circumcised penis are greater extent of protection against sexually-transmitted diseases, penile cancer, and future complications such as failure to retract the foreskin and tight foreskin (Cheng et al., 2006). Literatures also cover the cons of neonatal circumcision for which mothers should not circumcise newborn babies. These disadvantages include infections, excessive bleeding during the procedure, and accidental snipping of the glans or disproportional cutting of the foreskin so that it becomes either quite long or short. There could also be complications such as penile adhesions, scars, and tags that may necessitate surgery in future. Newborn male babies may also react adversely t o anesthetic medications used in neonatal circumcision procedures. Removing the foreskin could also make these babies’ private parts prone to stresses and friction as the glans would not be shielded from friction from clothing and kept moist and sensitive (Cheng et al., 2006). As mentioned earlier, opinions vary on the pros and cons of neonatal circumcision and it is imperative that parents seek divergent opinions on the matter before authorizing its performance on their newborns (Cheng et al., 20

Critically evaluate the argument that diversity management is good for Essay

Critically evaluate the argument that diversity management is good for organizations, but damaging for employees - Essay Example In forming this culture it is vital for the management to involve diversity initiatives in the business activities of the company. The top management should also promote diversity in the workplace as goal of the company. Diversity is about portraying a culture that recognizes personal needs and contributions. However diversity by nature is perceived to bring complexity in the workplace. This negatively affects the employees due the various cultures. According to Klarsfeld (2010, 126) Employees are bound to feel at ease when working with people from the same cultural background. Diversity management in the organization is good as it promotes maximum production compared to those organizations which do not employ diversity. Diversity as a practice starts and ends with the individual. Today diversity involves the all business practices driven towards creating trust and improving workplace. In order to maintain properly managed diversity in the organization it involves knowing workers ind ividually not as part of a particular culture. Organizations with multicultural diversity tend to portray high levels of engagement and the organization is able to outperform others. The outer-performance is in terms of stock price, turnover rate, stock price, revenue growth, net income and financial growth. According to Mor Barak (2010, 250), one of the important assumptions of diversity management is the strength of relationship between business assets. These include the business systems, practices, goals and the people involved. The compatibility of this interdependent relations as well as its well functioning affects the business operation. The effects are experienced in organizations image, profitability and stability which occur both in short-term or long-term. As suggested by Thomas (2006, 244), in diversity management, the organization needs to have an equal focus on all areas of management. Diversity in management has various benefits to the organization. They include: Easy entry to a changing market situation: Diversification in an organization implies incorporation of different practices. This means that the organization is less likely to have difficulties in adapting to changes. Working under diverse conditions enables the management to be able to handle various situations without fear. Diversity also means exploring various areas of the market therefore the management is aware of the market making its entrance easier. In diversity, employees are handled equally and this gives them the motivation to contribute the organizations development. High quality customer service: Diversification in an organization promotes enhanced customer services. The presence of individuals from different cultural background ensures that the organization can serve different customers and satisfy their needs. In diversity management since workers are used to working and relating with diverse cultural backgrounds, it becomes possible for them to handle different customers . Large-scale business transformation: transformation ensures business operation is more agile, rapid and lean. Diversity management ensures business operations are well transformed. It also ensure accountability in business transformation in large-scale. The diversity in the organization promotes modernization of business operations in business trans

The Contributions of Web 2.0 in E-Learning in Saudi Arabia Research Paper

The Contributions of Web 2.0 in E-Learning in Saudi Arabia - Research Paper Example Very many studies and researches have been carried out with the aim of promoting E-Learning as a means of fostering better education in the world (Webster & Hackley, 1997). Most of these researches have failed to contribute to the development of E-Learning due to various reasons especially in Saudi Arabia. One of the main reasons maybe their failure in assessing the relationship between Web 2.0 and E-Learning. Students in Saudi Arabia have shown less or no interest in using E-Learning as compared to their counterparts in Ukraine and Russia (Al-Jarf, 2004). Students are although still reluctant to accept E-Learning (Alenezi, Veloo, Karim, 2010, Al-Jarf, 2007). Several factors have been found to have significance contribution to the acceptance and use of E-Learning (Yi et al., 2001; Galletta et al., 1995). One of the factors that have had significance influence on E-Learning is the Web 2.0 technology. The use of Web 2.0 is on the increase; moreover, Web 2.0 features such as social netw orks have made enormous changes to various aspects of our lives. People involved with social networks can share their opinions, photos and videos, and they can learn many things that relate to their studies and their lives (Weaver & Morrison, 2008; Bemis-Dougherty, 2010). This research aims at establishing what contributions Web 2.0 technology has had on online E-Learning in Saudi Arabia. Aims of the research This research aims at: To spread the culture of technology that helps to create an e-learning community. To provide higher education for people who do not have the opportunity to join a university. Objectives There are several reasons as to why this research is significant and they are: To examine the number of users on Web 2.0 on education purposes To investigate challenges of using Web 2.0 on E-learning To provide an opportunity for many users to learn through Web 2.0 To determine how to reduce the cost of education using e-learning To determine how to boost the confidence of people who want to share To compare the gender differences as far as the use of Web 2.0 is concerned To determine the value of Web 2.0 for students To identify the barriers of using Web 2.0 in Saudi Arabia To determine the popular uses of Web 2.0 by students Literature review In this research, literature review will come from various studies and work from different information designs concerning with World Wide Web. Reports and other representations from individual researchers, as pertains this subject matter, will be used. Different reports that attribute to the effects of using the web, especially Web 2.0., on E-learning will be used to support the research. The researcher will determine the contribution of Web 2.0 in supporting e-learning in Saudi Arabia as discussed below. Examples of Web 2.0 support of E-learning Web 2.0 includes social network sites. One way of distributing information is to have the society accept it. E-learning is hugely enhanced by social networks. All age s are encompassed in this network. Every age is represented in this network. Information is easily shared if people consider it to fun. In order to embed a new culture into a society, the society must accept and welcome the new culture. Blogging is also provided by Web 2.0 where information is shared amongst a focus group, and each is allowed to give feedback. This is the best way of dialogue. A topic is provided, and people can give

In the decade of 1970, women's fashion trend reveals there had a Essay

In the decade of 1970, women's fashion trend reveals there had a strong intertwined relationship with political events and socia - Essay Example Fashion and design changed from being an elite group associated culture, but developed to incorporate the different age groups and genders for nations’ population. The designers had to put an extra effort in their artistic and designed works, so that they could come up with appealing styles and produce more for the vast population within their nations, and across their boundaries where the demand existed. It was a spontaneous thing to do for the growing markets in America, Europe and British among others. Some designers could not keep up with the current trend of the time, others had to lose some of their authenticity and adjust to the new changes, while for other designers, it gave them an opportunity for entering the industry and popularizing their new ideas works. Fashion boosted women careers and confidence in their new changing roles in official positions and politics, gave feminists more vigor, played a key role in opposition towards the governments and their operations, influenced by music (hippies, punk and rock) and social cultures. Fashion and Women in Politics The period after the 1960s saw women venture in politics and official positions in the government. ... Power clothes for women that expressed their new absorption and ability to perform in different careers that had been attached to masculininity became the new fashion, and career guide embraced by most working women at the time and later in the 80s (Hill 123). The power suit was the great design of the period that was tailored into different looks to distinguish it from the men’s suit style and looks. The variations of the power suits either with the men like pants or the ladies skirts as well as the make in different colors made the outfit even more diverse, and acceptable for women in high demand markets. The professional look was promoted by the influencing fashion that saw women dress in designer blazers and pants, official jackets and skits sets among other lines of power suits as designed by Karl Lagerfield (â€Å"Fashion† thepeoplehistory.com). It demonstrated equality in work places and power opinion for the working women in their careers. While seeking their ri ghts, liberation, and being free from male supremacy in their societies, the women's movements in the 1970s gave an opportunity for women to dress in fashionable pants designed for women, as way of sending a political and social message to change the oppressive social structure and enhance equality. According to Coen, the 1970s second wave of feminism greatly contributed to power suit acceptance as female wear, with the suits exaggerating women’s shoulders, skirts and trousers worn with relaxed jackets indicated how women intended to climb the ladder of success and how their presences was a force to be reckoned (mancunion.com). The famous designs of Yves Saint Laurent (YSL) can demonstrate more with his influential work in

Sociology Term Paper Example | Topics and Well Written Essays - 1000 words

Sociology - Term Paper Example Social events vary in a wide range, due to the variations in human tendency and behavior. Analyzing the reason behind social events requires a psychological study of human behavior, as that strongly holds the ethics of religious, cultural and community values as its background. Matthew Desmond in his book analyzed the subjective facts of individual psychology of temptation and risk bearing factors. Fighting against the forest fire is a life taking job but the country boys, in their every efforts, tries to prove their braveness by accomplishing the challenging job. Every forest fires are followed by death, injuries and bone breaks; but they never give up fighting against it (Desmond). Hence, the factor behind the human guts must be very personal; the responsibility they feel about rescuing forest from fire, to maintain their identity as a firefighter and also the inability to do the same would be a question to their masculinity. All the mentioned factors seem to have their connection with the psychological prospects of an individual with his ethical values. Psychological factors are equally responsible for the involvement of individual in any social events. On this contrary Randall Collins, emphasizing on micro-sociological theory, gives stress on social violence as a result of the big shape of emotions in an individual, connected to several past and present happening in his/her life. For example: poverty, race, and origins in divorce or single parent families etc. Human psychological condition of fear, insecurity and inferiority leads to the violence of different kinds. For example: mass murder, serial killing, revenge taking, sexual abuse and suicide. He insists on the use of the modern technology to give authentication to the findings. As per Collins, police normally uses the available data to confine the cause of the happening. But such empirical data are not liable to give psychological justification to the case. The use of micro analysis theory becomes a n ecessity, in such cases, as that can draw out the emotional involvement of the individual in a particular social event (Collins). As these two frameworks, seem to have the similarities with the Comte’s social theory of positivism and anti-positivism. Where, Collins views inclines more towards anti-positivists whereas Desmond towards positivists. Giving stress to positivism, Durkheim maintained that the social sciences are a logical continuation of the natural ones into the realm of human activity, and insisted that they should retain the same objectivity, rationalism, and approach to causality. This approach eschews epistemological and metaphysical concerns such as the nature of social facts, in favor of methodological debates concerning clarity, reliability and validity (Wacquant ). Supporting anti-positivism, sociologist Max Weber argued that sociology may be loosely described as a science as it is able to identify causal relationships of human "social action", especially a mong "ideal types", or hypothetical simplifications of complex social phenomena. Karl Marx's methodology is borrowed from Hegelian dialecticism but also a rejection of positivism in favor of critical analysis, seeking to supplement the empirical acquisition of "facts" with the elimination of illusions. He maintained that appearances need to be critiqued rather than simply documented

Based on your research and experience critically assess how values and Essay

Based on your research and experience critically assess how values and beliefs have changed in Britain over the last century. An - Essay Example These words by one of Britain’s most influential and famous statesmen certainly echo the central themes of this essay. On no level more so than the values and beliefs of the British people has the nature of the United Kingdom changed during the course of the last century. The effect these changes have had will certainly manifest currently, and continue to affect contemporary the youth in the 21st Century, in varied and significant ways. At the turn of the last century, as the world moved into the 1900s, Britain and her Empire stood at the forefront of the world, dominating culture, belief systems, education and politics across the globe. It seemed that the historic continuity of the kingdom would last forever. And throughout this history, Britain was part of Europe, sometimes at war with countries on the continent, sometimes in alliance with them, but always connected to them, perhaps due to proximity. But is has also been due to the close bonds that Britain and the British pe ople have had with European values and beliefs, particularly those of Western Europe, that these ties have remained. And certainly throughout the last century, Britain has been the defender of the values and beliefs of Western Europe (Thatcher, 1988). ... Importantly this system also derived from European influence and philosophical thought. Throughout, Britain has recognised the personal liberty of the individual, and a human rights culture, based on responsibility and duty to the collective, rather than personal gain exclusively (ibid). The religion of Britain and the European continent at large, Christianity, has consistently informed the value systems of Britons, leading to particular set of morals to inform behaviour that is considered acceptable or unacceptable (ibid). Defending this ideal of behaviour, government and civilization has at least twice forced Britain into taking the lead in successive world wars: In both World War I and II, the kingdom did not hesitate to stand up to the forces of autocracy and fascism, respectively, and risk all in defending the democratic rights of its own citizens, as well as the rights of all free peoples to remain free (The Staff of the New York Times, 1965). Continually, though, Britain has a sserted its sovereignty, interacting with Europe and the rest of the world, yet remaining defensive of its own culture, values and civilization. The perception that Britain was leading the world certainly rang true at the beginning of the 1900s, and continued to be valid for at least the first half of that century. It was never in doubt that the British way of life was enviable, defensible and something to be proud of for most Britons. As the Empire declined, and the 20th Century drew to a close, though, both Britons’ own opinions, and world opinion was that the United Kingdom was no longer a world super-power. Perhaps this is in part the explanation

Organizational Restructuring, Changes in Strategic Management, Essay

Organizational Restructuring, Changes in Strategic Management, Deregulation in T-Mobile - Essay Example The service sector in the United States that T-Mobile is breaking into has been growing consistently with an urbanizing global market in terms of providing services, and the dependence is necessary to focus upon in terms of putting the consumer first. Management seems to reflect this through the strengths of planning for customer service and effective target marketing. T-Mobile management must act in a very dynamic and competitive industry. The United States also occupies a strong position in the services market and has many advantages in this sector because international companies are becoming used to an atmosphere of deregulation that has expanded domestically. This allows corporations to take more advantage of being agents of change in previously regulated industries, in which products and services are now subject to the laws of supply and demand rather than the laws of the government. Therefore the company’s product strategy revolves around the provision of cell-phones and cell-phone services in this competitive environment, with an eye on the future of Wi-Fi, which seems to show effective managerial planning. T-Mobile managers have also shown strengths of organizing in a deregulated market and adapting to quick changes. Deregulation required that established companies to offer open access to communications channels instead of charging competitors or denying them access and thus eliminated this entry barrier in the telecommunications industry. In the second barrier, that of cost disadvantages independent of scale, an established company may have proprietary rights to certain technologies which make it difficult or impossible for a competitor to gain a real foothold in the industry. These types of situations can sometimes be handled legally, but this is not cost-effective for the company just starting out in the market. An established  competitor could also simply have so much experience in an industry that it is able to outdistance competitors and potential entrants on this virtue alone.

Risk Factors That Increase Stress in Modern Day Adolescents Essay Adolescence is a time of growth and development. It is a transitional stage between the dependency of childhood and independency of adulthood. Thus, it is not surprising that adolescence is noted to be a juncture of high distress. Risk factors and causes of stress in adolescence must be determined first and foremost, so that appropriate coping strategies can be developed to deal with this issue. Stress is defined as conditions or events that test a persons psychological capacity to adjust or respond to these circumstances (Garcia, 2009). The conditions, in which a person determines as stressful, vary depending on the individual. Adolescents experience of stress can be perceived as intolerable, due to their lack of knowledge and understanding of how to appropriately deal with their distress (George van der Berg 2011). Byrne and Mazanov (2002) established seven areas that predispose adolescents to increased stress levels. These include school, family relationships, future prospects and peer interactions (Byrne Mazanov 2002). Negative family interactions have been found to be the most compelling stressors for adolescents (McNamara 2000, pg 39). Unstable family structure, parental disagreements and inadequate child care can have a detrimental effect on an adolescents well being (Menaghan 2010). As adolescents are still developing physically and mentally, the requirement of a constant and secure home life is especially beneficial to their growth into adulthood. Most family related stressors can be classified as trivial or minor disagreements between an adolescent and parent (McNamara 2000 pg 40). When these discrepancies escalate into severe conflicts, the resultant adolescent is more inclined to have doubt in their self-worth, and depleted confidence in their ability to achieve, therefore losing all motivation to accomplish goals (McNamara 2000 pg 42). This in turn can predispose the adolescent to stress related conditions such as depression and self destruction (George van der Berg 2011). Peer relationships can be the most influential aspect on an adolescents  decision making process (McNamara 2000, pg 41). The need to fit in and feel validated by their peers can cause great distress, which can have a colossal effect on choices an adolescent makes. Peer pressure, bullying and fear of rejection are a few of the many social issues, youths face on a daily basis through school and social activities, such as youth groups and sporting events. The resources that they have access to, can either enhance their well being or cause an adolescent a great deal stress. Preconditions, such as negative family/home situations and genetic predisposition to mental illness, can increase development of problem behaviour in teens (McNamara 2000, pg 54). Poor self perception and lack of self esteem can make it difficult for an adolescent to build rapport with other peers, leading to anti-social and self-harm tendencies. Although peer interactions can manipulate an adolescents way of thinking or choices they make, lack of peer relationships can lead to depressive or aggressive attitudes (George van der Berg 2011). The burdens of school attainment includes future uncertainty with career and further education prospects, and current stressors such as the need to achieve good grades to accomplish these goals, and exam pressures (George van der Berg 2011). Added parental pressure to achieve high marks can also cause negative performance anxieties, due to the adolescents uncontrollable desire to please their parents scholastic achievement dreams of them. Competition between peers to achieve good grades for acceptance into reputable tertiary intuitions, can furthermore add to the distress caused on teenagers through education and peer rivalry (McNamara 2000). Constructive and supportive learning environments can be beneficial to an adolescents growth and development. This can support an overall higher achievement rate and feeling of satisfaction in student, teacher and parent (McNamara 2000). Research into adolescent stress has increased considerably over the past twenty years. With the ever advancing development of new technologies, Byrne and Mazanov (2002) concluded that their study into psychosocial factors that increase stress in adolescents must be modified and adjusted to suit the specific era. For example, twenty years ago issues with cyber bullying were  nonexistent. With this knowledge it is important to be aware of any new possible causes of stress in adolescents, and adapt the stress measuring apparatuses and questionnaires as required. Outlining the specific areas that youths find the most distressing, can assist adolescent professionals and parents alike to be able to recognise and treat the symptoms of stress before it gets out of control. It is important to acknowledge that stress and the ability to be able to adapt to different situations is not always a negative experience. From examining numerous case studies and experimental questionnaires on adolescent stress, I have been able to determine that there are three main significant areas that all adolescents find cause anguish in their lives. These factors are schooling, friendships and parent/child relationships. If these areas are controlled in a compassionate and understanding environment, there is greater chance of those adolescents developing appropriate coping strategies that they can continue to use into adulthood.

History Of Optic Fiber Usage Information Technology Essay

History Of Optic Fiber Usage Information Technology Essay The idea of fiber optics communication system is basically sending information through light. Optical fiber was first developed in 1970 as a basic communication purpose with a very low attenuation as transmitting light through fiber optics cable for long distance communication. In 1975, the first commercial fiber optics communication system was developed using semiconductor laser and operated at 0.8 Â µm wavelength and a bit-rate of 45 Mbps (Mega bits per second) up to 10 km (Elion Elion 1978) (Sullivan Curt 2003). In long beach California was the first live telephone traffic sent at about 6 Mbps and it was in 1977. After that, generations of fiber optics system technologies were developed, improved, and upgraded to achieve the first transatlantic operation in 1988. All fiber optics systems are limited by something called dispersion. The initial thought of fiber optics was an experiment involving a bucket of water and sunlight. It demonstrated the suns reflection within the bucket with a hole and water pouring out illuminating the water and the sunlight can be seen in the stream of water (Elion Elion 1978). Then it moved on to optical voice transmission known as photo phone. Further, it went to fiberscope that was used to inspect welds within reactor vessels, combustion chambers of the jet engines, and then to the medical field utilized in laparoscopic surgery. Researches and improvements continued through the fiber optics generations to overcome the dispersion phenomena by using dispersion-shifted fibers to minimize the dispersion at 1.55 Â µm or by limiting the laser spectrum to a single longitudinal mode (Alwayn 2004) (Sullivan Curt 2003). The idea of using fiber optical amplification came with the development of the fifth generation. The amplification development reduced the need of using repeaters and wavelength division multiplexing (WDM); which will be described in details later; and increases the data capacity. By these developments, a bit rate of 10 Tb/s was achieved in 2001. The developments of fiber optics generations are a continuous operation to especially for the huge market of the internet communications which requires an increase in communications bandwidth such as video on demand. These growing in using internet protocol data traffic are increasing side by side with faster rate integrated systems complexity. (Elion Elion 1978) Fiber optics manufacturers had reduced the cost by the huge request of communication companies such as ATT to take the advantage of delivering the technology of internet and telephone through higher data broadband services to customers homes (Sullivan Curt 2003) (Snell 1996). Fiber optics is already being used nowadays in military and commercial aircraft, and some of the areas it altogether replaced the Digital Flight Data Recorder with the newer Distributed Flight Data Acquisition Unit that performs the same thing but evaluates much more information. Indeed, future aircrafts will see fiber optics technology in the flight controls. Fiber optics has evolved practically from ideas to a thing of the future (Alwayn 2004) (Elion Elion 1978). Fiber optics Application The demand and usage of optical fiber has grown rapidly and optical fiber applications are numerous. Ranging from global networks to desktop workstation, telecommunication applications are widespread. These involve the transmission of data, voice, or video across distances of less than a meter to thousands of kilometers by utilizing one of a few standard fiber designs within one of several cable designs. Optical fibers are used by carriers to carry plain old telephone service (POTS) over their nationwide networks. Furthermore, local exchange carriers (LECs) employ fiber to carry the same service across central office switches at local levels and often as far as the individual home (fiber to the home, FTTH) or neighborhood (Alwayn 2004) (Elion Elion 1978). Moreover, optical fiber has a widespread use in transmission of data. Multinational firms require reliable and secure systems for transferring data and financial information among buildings to the computers of desktop terminals and around the world. Fiber is also used by cable televising companies in order to deliver digital video and data services. Due to the high bandwidth offered by fiber, it is the ideal choice for transmitting broadband signals like the high-definition television telecasts. Furthermore, intelligent transportations systems including smart highways equipped with intelligent traffic signals, changeable message signs, and automated tollbooths, also utilize telemetry systems based on fiber-optics (Alwayn 2004) (Fiber-Optics.Info 2010). Biomedical industry is another significant application of optical fiber. Fiber-optic systems are used in almost all modern telemedicine systems and devices for transmission of digital diagnostic images. Additionally, other applications for optical fiber also include military, space, industrial and the automotive sector (Elion Elion 1978) (Snell 1996). Fiber optics communication technology is used by todays telecommunications companies such as ATT in the United States and BT in the UK. Also it is used by internet providers and cable television signal providers such as Sky. For the huge expense of fiber optics system, the technology was first used for long-distance communication only. But, now days developments of the cities infrastructure had to take place to install the fiber optics communication system regardless of the cost and time consuming. The challenge of fiber optics technology companies was reflected positively on the market and the cost of fiber optics communications dropped considerably (Alwayn 2004) (Elion Elion 1978) (Fiber-Optics.Info 2010). By the developments of optical amplification system, an intercontinental network of 250,000 km of submarine-communication-cable was developed with a capacity of about 2.5 Tb/s was achieved. Also, the optical communication system was installed onboard aircrafts for data, video, and radio signals communication. It was first introduced to aviation industry by NASA researches on military aircrafts such as the first F/A-18 hornet through its RTDP; radar tracking and detecting system processor, missile video tracing system, and with the FLIR system; forward looking infra red sensor, and the integrated radar system with increased speed and memory capacity. Military aircrafts are always in-need to reduce weight when it is in slick phase to improve its capability of maneuvering and delivering various types of ordnance in a very precise targeting and accurate guidance. Lately, this technology was used on the F-22 airforce raptor on its high speed data bus and fiber optics transceiver (Alwayn 2004). This idea was reflected on the civil aircrafts later on as they always in-need to reduce weight to overcome the fuel usage and deliver larger number of passengers which means saving mo ney and increasing profits. Besides that, the new avionics systems technology and complexity required new communication system other than the copper wires such as the normal ARINCs (Fiber-Optics.Info 2010). Boeing and Airbus developed very complex integrated systems that control the aircraft performance at an altitude of 30,000 ft and above which required bigger and more complicated communication systems which means: More chance of shorting the wires. More EMI (electro-magnetic-interference) which can cause a distortion for the signals More weight More chance of shorting and cause sparks and fire on-board and aircraft The first official usage of fiber optics technology usage was on-board the Boeing 777 after the development of its AIMS (Aircraft Information Management System) which have more than 2 million of computer codes. Also Boeing 777 was the first aircraft to install an optical LAN (local area network) for on-board data communication and on its cabin systems communications (Sullivan Curt 2003) (Snell 1996). After that, fiber optics system was installed on the Boeing 757 flown by Air Mexico who did not experience a single failure. So here comes the safety, reliability, durability and stability of signals communications on-board an aircraft which can make the affordability part negligible. We have to mention that the cost of optical fiber systems are dropping for the establishments and marketing competition of huge number of manufacturers and suppliers (Alwayn 2004) (Fiber-Optics.Info 2010). Fiber Optics vs. Electrical Copper Wires: Fundamentally, there are three types of transmission media: copper wires, waveguides and free space. Copper wire, such as coaxial cable is broadly used. A signal is transmitted across the wire in either digital or analog form to a receiver placed at the end of the wire. Free-space transmission is also widely used through which radio, television and other across-the-air signals are carried. Waveguides describe the fiber-optic transmission. Significantly, a waveguide such as a optical fiber restrains the electromagnetic radiation, light (Bidgoli 2010). Fiber optic transmission provides the best elements of both free-space and coaxial transmission. It is capable of carrying a signal from point A to point B in the absence of any limited electromagnetic spectrum. Nonetheless, it does not suffer from limited data rate and bandwidth is the same way as the coaxial cables do. The advantages of fiber optics system over the copper wires are: No Electro-Magnetic-Interference (EMI). No radio-Frequency-interference (EMF). Immunity from electromagnetic noise High Signal quality Lighter weight cables Longer distance capability (Bidgoli 2010) Smaller diameter cables which mean saving more space. Greater bandwidth for data transfer Safety against shorting and sparking High bandwidth and greater information capacity Easy upgrade: Can be upgraded easier without ripping and replacing cable harnesses. Easier maintenance and handling, proved by Boeing and Lockheed martin engineers Lower cost (Bidgoli 2010) Lower signal loss for long distance communication Higher resistance against stress, temperature and vibration and higher lightning strikes incidence. Doesnt require repeaters for long distance communication Can operate for up to 100 km without passive or active processing But, we have to say that copper wires have some specifications that fiber optics doesnt: Can carry electrical power beside the signals Lower material costs Doesnt have minimum bending radius Can easily be installed between boxes and chips (Bidgoli 2010) Cable technology is used for connecting networks together; however, as optical fiber technology is moving forward, it is gradually replacing copper wires as an excellent medium of communication signal transmission. The main reason for this is that fiber optics offers much more benefits than conventional copper wires and cables, as stated above (Sullivan Curt 2003). Moreover, these benefits can be elaborated as follows: Resistance to Interference: Fiber optics do not conduct electricity as it is obtained from glass, which eliminates activities like grounding and makes it potentially immune to electromagnetic interruption. Working of Fiber optics, unlike copper cables, is based on light pulses that make it usable outdoors and in close proximity to electrical cables (Bidgoli 2010). Low Maintenance: This entails that optical fiber is not sensitive to elements like water and chemicals because it is produced from glass. Additionally, Fiber optics cannot be damaged by harsh elements. This makes the overall cost of maintenance and service lesser than its counterpart. Efficiency and Security: Information can be transmitted with greater fidelity with the help of fiber optics unlimited bandwidth. It can offer nearly 1,000 times as much bandwidth across distances approximately 100 times farther than copper cables. This provides a super-fast connection running in circles around the bandwidth assigned by cable connections. Moreover, since fiber optics is harder to tap than regular copper wires, it can offer additional data security (Bidgoli 2010). Picture Quality: In comparison to copper wires, the high quality technology embedded in fiber optics is much more powerful. One can obtain high-definition picture quality from fiber technology as there is no external interference. Safety: Fiber optics poses no threat of physical injuries during breakage of fiber optic cables. Instead of transmitting through electricity, it transmits data via light. Users face no risk of injury from dangers such as sparking, electrocution, fire, etc. (Bidgoli 2010). Interestingly, the benefits of converting into fiber technology such as Ethernet converters show proven advantages, considering that internet infrastructure is steadily making this transition rather than conventional copper cabling. Furthermore, applications of fiber optic include manufacturing and process control, supervisory control as well as data acquisition. Using transceiver modules provide a cutting edge and most importantly the highest quality data transmission for users television, home phone and internet (Sullivan Curt 2003). Basic components of fiber optics system: It is consisted of: Core: it is basically a cylinder of glass or plastic material. Cladding: a layer causing the light signal to be confined to the core by using the total internal reflection method. Buffer: a layer used to capsulate one or more core and cladding providing mechanical isolation and a protection from physical damage. Jacket: a further isolation and protection. Characteristics The major characteristics of optical fiber transmission lines are: Attenuation and its variation with transmission input wavelength, cable temperature and modal distribution. Radiation: and its variation with fiber temperature and bend radius Distortion and its variation with bandwidth, amplitudes, wavelength and modal distribution of the input light, length of the fiber, and lastly, environmental temperature (Snell 1996) Physical Parameters: This includes weight, size, ease of installation, total volume, coupling and splicing. Environmental parameters: This includes resistance to stress, water and chemical corrosion, temperatures and mechanical stresses (Alwayn 2004). Types: single mode and multi-mode fibers. A single-mode optical fiber Multi-mode optical fiber There are two categories of optical fibers, namely, single-mode fiber optical cable and multi-mode fiber optic cable. In essence, these types of fiber optic cables are comprised of numerous layers of glass, each having refractive index lower than the one next to moving from the center outwards. Since light is faster in lower glass refractive index, the wavelengths of light are broken outside the fiber, capable of traveling to the middle (Snell 1996). Multi-mode Fiber Optic Cable: Optical fiber with a base diameter greater than 10 microns can be analyzed through geometrical optics, and is called a multi-mode fiber. In this type of optic cable, the rays of light along the core of the fiber are led by total reflection. Moreover, rays meeting the core-mantle border at a high angle over the critical angle for this limit are fully considered. The critical angle is said to be the difference in refractive index between the mantle and core materials. Rays hitting the border at a shallow angle form the base breaks into the mantle and does not transmit the light and information along the fiber. Moreover, the acceptance of the fiber is determined by the critical angle, and is often referred to as a numerical aperture (Snell 1996). A greater numerical aperture allows light to spread into two distinct beams at different angles near the axis, for the effective coupling of light into the fiber. Single-mode Fiber Optic Fiber Fiber core diameter of nearly ten times the wavelength of light propagation is impossible to model with geometric optics. Rather, they can be studied as an electromagnetic structure by solving Maxwells equations that are reduced to the electromagnetic wave equation. It acts as an optical waveguide and supports one or more confined transverse modes which allows light to propagate through the fiber. Fiber that supports only one mode is known as mono-mode or single mode fiber. It is an extremely focused source of light which limits beams to a smaller range or angles closed to the horizontal. A fiber optic data cable has three primary functions. It converts an electrical input signal into an optical signal, transmit the optical signal across an optical fiber, and lastly, convert the optical signal back to an electrical signal (Green 2006). Transmitter: It is a semiconductor device and can be an LED (light emitting diode) or a laser diode. It converts the electrical input signal into an optical signal, and its drive circuit changes the current flow across the light source, which in turn changes the irradiance of the source. This process of changing the irradiance of the source as a function of time is known as modulation. Receiver: It is a photo-detector and the main component of the receiver which converts light signals into electrical using the photoelectric effects method. It is basically a semiconductor-based photodiode. Amplifier: it is used instead of the complex repeaters. It amplifies the light and optical signals without converting it to electrical. Fiber-optic telecommunication systems operate on pulse-code modulation in which information is sent across as a series of pulses. Moreover, the digital pulse-code modulation is coupled into a fiber and the fiber end set up by a connector in order to maximize the input power. In fiber-optic communication systems, semi-conductor lasers are best suited. Their shape and size enables efficient coupling of light within the small-diameter core of an optical fiber (Sullivan Curt 2003). The fiber then carries the light towards the receiver which detects the light and recovers the digital signal. As scattering, dispersion and absorption in the fiber degrade the signal, optical amplifiers must be used to regenerate the signal (Snell 1996). The U.S. military quickly turned towards fiber optics for enhanced and improved communications as well as tactical systems. During the early 1970s, a fiber optic telephone link was installed by the U.S. Navy aboard the U.S.S. Little Rock. Toward that end, The Air Force developed its Airborne Light Optical Fiber Technology (ALOFT) program in 1976. Greatly motivated by the success of these practical applications, military R D programs developed stronger fibers, ruggedized, high-performance components, tactical cables, and several demonstration systems that ranged from aircraft to undersea applications. Soon after, commercial application followed that included both ATT and GTE installing fiber optic telephone systems in 1997 in Chicago and Boston respectively (Green 2006) (Keller 2010). Therefore, these successful applications resulted in the increase of fiber optic telephone networks. In the early 1980s, single-mode fiber running in the 1310 nm and then in 1550 nm wavelength ranges we re installed for these networks. Earlier, information networks, computers and data communications were far slower to employ fiber; however, today they are embracing the transmission system that has lighter weight cable, carries more data faster and across long distances, and resists lightning strikes (Elion Elion 1978) (Snell 1996). An average aircraft consists of over hundred miles of electrical wires and controls almost everything from landing gear to calls from flight-attendants. These insulated copper wires have proven to be a big bottleneck: it is heavy in weight, vulnerable to electromagnetic interference and if not accurately maintained, can cause system failures or fires. Some of these wires can be replaced with fiber-optic technology that is lighter than copper wire, immune to electrical shocks, and less sensitive to electromagnetic interference (Green 2006). Researchers have developed a new optical switch to be incorporated into the cockpit controls in order to manage operations that involve turning on and off, for instance, displays, landing gear, manual switching between fuel tanks, etc. Presently, on-off switches in a cockpit are connected to separate wires spread throughout a plane, controlling several functions. In case a switch fails to work due to wiring problems at the inside of the plane, dete cting the offending line can consume a lot of time and effort, since the wires are usually bundled together. Therefore, this switch is capable of sensing whether a button has been pressed fro off to on (Keller 2010). Then, the information from the fiber-based device can be directed toward a main fiber artery that carries hundreds of signals simultaneously. Through this, the bulk of wires, and cost is eliminated, and maintenance is simplified. Although engineers have been working to replace aircraft wiring with fiber for several years, unfortunately, they have had only moderate success. Built in mid-1990s, Boeings 777 uses a fiber-optic communication network, but the design and implementation being a part of an experiment. Moreover, the network was not a critical system and it was over-designed with more possibility of error than greater cost-effectiveness if in case it was broadly implemented in the industry. Nevertheless, Boeings 787 aircrafts, is equipped with a more cost-effectiv e optical fiber communication network (Green 2006) (Keller 2010) (Sullivan Curt 2003). ARINC 429 The first major variation in avionics databusing on military as well as commercial aircraft came during 1970s and 1980s. It was deployed as a 100 kilobit-per-second ARINC 429 databus which is a multiplex databus standard of ARNIC Inc. The databus is omnipresent on commercial airliners and is one of the most common avionics equipment used in flying today. The ARNIC 429 is equipped by all commercial aircrafts for legacy connections and for securing backup for flight critical controls. The ARNIC 429, apart from being the de-facto standard, is used on aircrafts for digital electronics, navigation and air data computers, engine control systems, and radios which are fully computerized and need to interact with each other. Furthermore, ARINC 429 is greatly responsible for setting up the digital era in commercial and military avionics. However, it is a comparatively slow twisted-pair databus and unidirectional like 1553. Only one terminal on the bus can broadcast and as much as 20 terminals can listen (Keller 2010). The ARINC 429 represents a tightly legalized architecture equipped with standard ARINC connectors. Before the introduction of ARINC 429, avionics designers utilized hard-wired point-to-point connectors with analog signals suitable for every sensor type, like the navigation gyros. Many sensors had multiple wires and multiple signals. In typical applications deployed on todays jetliners, systems designers extensively utilize ARINC 429 in order to connect avionic subsystem boxes and components digitally. One master subsystem on the bus sends information to at least 20 slave subsystems, but the slaves are unable to send information back to the master. Therefore, to enable a slave subsystem to transmit data back to the master, another ARINC 429 bus is used with its direction reversed, thereby enabling the original slave to send and the original master to listen. More frequently, designers make use of two ARINC 429 buses, amounting to point-to-point bi-directiona l interconnections between avionics subsystems: one bus transmitting in one direction, and another bus transmitting in the reverse direction (Green 2006) (Keller 2010). One such example includes jetliners flight-management computer that accepts and processes inbound signals from several different sensors and other subsystems, and estimates the paths taken by flights, their time of arrival, fuel burn, etc. In this approach, ARINC 429 busses send information from the sensors and allow the flight-management computer to listen to that data. Whenever the flight-management computer needs to transmit information tack to a particular sensor, designers employ another 429 bus that runs in the opposite direction. Regardless of its low speed, the digital ARINC 429 databus aids in increasing the efficiency, speed, and facilitates maintenance since it can move several digital data packages across the same twisted pair, where analog approaches required a different wire for each signal (Keller 2010). The digital ARINC 429 bus allows for multiplexing of the information on two wires. Since it is capable of sending data across only in one direction, it is greatly reli able due to its lower possibility of data corruption or data conflicts. Furthermore, this reliability of the databus makes it usable and well-known for flight-critical data involving avionics activities such as flight navigation and engine control (Keller 2010). The sheer size of ARINC 429 installed base drives its popularity; it is included in almost every commercial jetliner recently manufactured. ARINC 429 has limited addressing capacity and limited bandwidth; still it is proved as a highly robust physical bus and has served the industry well enough for several years. Moreover, it is a viable bus and protocol where installations require limited bandwidth and limited address space on the bus. However, modern avionics architecture demands more bandwidth, more address space, and greater flexibility than what the ARINC 429 can deliver (Keller 2010). ARINC 629 ARINC 629 is a 2-megabit-per-second databus that is borne from the MIL-STD-1553 technology. The conversion into an ARINC 629-type of bus topology strongly supported the move in the aviation industry to greater degrees of integration within the full systems throughout the avionics and the aircraft systems. The launch of ARINC 629 was set up on the highly-advanced architecture of the Boeing 777 double-engine jumbo jetliner. After its launch, the databus started as a Boeing invention known as Digital Autonomous Terminal Access Communications (DATAC). In comparison to ARINC 429, 629 is a completely different model altogether. It is bi-directional and does not need the master, which has been a potential single point of failure in 429. Although it is a sporty technology, it is still expensive. Additionally, ARINC 629 is far more cognate to 1553 than the ARINC 429, which has bi-directional flow of data (Keller 2010). One of the most attractive aspects of ARINC 629 was the bus efficiency, or rather the ratio of actual data transmitted by the bus to the routing overhead code. ARINC 429 has an efficiency of nearly 45 percent; however, with ARINC 629 efficiency can reach up to 85 percent if the bus is architected right. Furthermore, as compared to 429, ARINC 629 is a bus without connectors. In the ARINC 629 a twisted pair of wires is fed across the bus coupler that behaves like a transformer. Nonetheless, it was the price of the bus that got designers in a dilemma about the usage of ARINC 629. Although, ARINC 629 was more reliable, but it was much costlier than what the designers had actually thought (Keller 2010). Cost concerns, a lack of large new commercial aircraft projects when Boeing developed the 777, and the increasing popularity of Ethernet networking technology blended together to halt implementation of the ARINC 629 after the 777. ARINC 629 is heavy and expensive to implement. Future Fiber optics is anticipated to have a better future in military aviation industry. It exclusively provides high bandwidth, immunity against electromagnetic interference, and is light weight. Optical fiber was deployed on the AV-8B several years ago; it is used across the F/A-18E/F including several other aircrafts, and is likely to be fielded at a higher degree in coming years. However, before fiber-based applications in intense aviation environment can proliferate, a couple of standards are required in component, training, testing and other areas. Techniques such as WDM, short for wavelength division multiplexing, might dramatically increase the throughput and lower the footprint needed today for analog and digital data communications, beyond the immediate horizon (Keller 2010) (Sullivan Curt 2003). Fiber optic standardization within the aerospace sector leaves out something to be desired. Unfortunately, there are no standards for: The method for computing link loss power budgets The geometrics of critical parts like the end faces of optical fiber cable terminations, and Training military aviation personnel and technicians in the handling of optical fiber There has been a consensus for standardization. Operating with the Society of Automotive Engineers (SAE), NAVAIR, short for Naval Air Systems Command, avionic companies, airframers and components suppliers have put extreme efforts in developing training standards and components to enhance the supportability of current systems, and to cover various emerging technologies. In essence, fiber optics has been a corporate initiative within NAVAIR, holding its base in the commands Avionics Division instead of a particular program office (Adams 2005). Fiber optic technology has evolved at the major contractor or airframer level, in military aviation, as stated by researchers, engineers, personnel, and F/A-18 fiber optic experts with PMA 265 at NAVAIR. Fiber optics avionics components standardization will greatly assist in eliminating ambiguities and allowing test and inspection of equipments in order to sufficiently cover the technology fielded today (Adams 2005) (Sullivan Curt 2003). JELLI JELLI is an SAE group that is developing performance standards for the initial test and inspection processes of avionics fiber optic assemblies. JELLI is short for jumpers, endfaces, link loss and inspection; i.e. the processes and components used in optical networks. They are supported by the following definitions: Jumpers: The cables that are utilized in testing the overall optical performance of the fiber optic cables after installation. Endface: This is the polished end of the high-precision ceramic cap of the fiber optic termination that enables optical coupling. Link Loss: It is the attenuation of the signal, primarily from connector loss, and Inspection: It involves the examination of a cable installation in order to verify its performance. Different polish standards are required to apply to the physical vs. non-contact connections. However, within those areas, everyone should satisfy a termination endface range for that kind of polish. The cleanness of the endface is another important parameter. Test jumpers have endfaces and their polish requirements must match the component being installed within the aircraft. The test jumpers fail work on the airplane without such as standard (Adams 2005). Furthermore, standards for components like endfaces are essential to eliminate subjectivity on the engineering side. Additionally, it is mainly important since aircrafts with fiber optic systems have been launched in order to set up a baseline for the avionics technicians, and to instruct them on what exactly a good connector endface. In essence, work on inspection involves the magnification and several other criteria required of the equipment that is used for examining the termination endfaces and detect damages. For instance, tiny char

Causes of Ethical Dilemmas in Social Work Practice

Causes of Ethical Dilemmas in Social Work Practice Shaun Wharton Understanding the term ethical dilemma and how such dilemmas arise in social work practice. The paper will begin by explaining the term ethical dilemma and how such dilemmas arise in social Work practice through; what conditions and components are needed for an ethical dilemma to develop, and by explaining how ethical dilemmas occur within agency policy, law, professional ethics and personal values. Furthermore the paper will apply agency policy and law to the case study of Jack, a 62 year old white man, in order to explore how ethical dilemmas arise within social work. The paper will then explore risk verses autonomy, by weighing up the consequences for and against supporting Jack, through utilitarianism, deontology, and virtue ethics. This will then lead to explore a new proposed action. Finally the conclusion gives a brief summary and critique of the findings. The first part of this essay will explain the conditions and components needed for an ethical dilemma to develop. Firstly there has to be a difficult decision made with two or more unwelcome courses of action avail able (Banks, 2006, p.8). Secondly no matter what course of action has been undertaken, an ethical principle has been bent or broken (Allen, 2014). Once you have made a decision then the social worker is left responsible for choosing an imperfect answer and the inevitable unwelcome out comes (Banks, 2006, p.9). This paper will now explain when an ethical dilemma occurs, firstly through agency policy and law, these are integrated into every course of action, and decision made. One important act is the Human Rights Act and is integrated into UK law. This means that every person can protect their rights in court and public organisations have to treat everyone equally. (Minister of Justice, 2006). Social workers often only have one course of action to take and that’s to follow the law and agency policy (hcpc, 2012). Sometimes social workers professional codes of practice might come into conflict with law and agency policy, this is not an ethical dilemma because there is only one course of action to take, for example they should follow the law. Additionally due to the social workers codes of professional practice you are obligated to lobby against such law (hcpc, 2012). In contrast Braye and Preston Shoot (1997) suggest the law is vague, leaving the social workers to decide what course of action to take, producing ethical dilemmas (Banks, 2006, p.8). Secondly Professional ethics can result in ethical dilemmas for example, when trying to choose the best course of action in relation to a service user (Allen, 2014). Ethics are a professional guide (morals actions) set out to help people in groups or within a professional organisation to make right decisions, when an ethical dilemma presents itself. In social work this is the health and care professions council (hcpc) and offers a set of ethical principles to determine the right course of action and therefore produces a logical thought process, resulting in consistency throughout the profession. (Parrott, 2011, p.79). In contrast, the social workers, hcpc codes of practice covers a large range of codes of behaviour and conduct (Banks, 2006, p.78), therefore blurring professional boundaries, (Banks, 2006, p.16), which result in ethical dilemmas (hcpc, 2012). Finally Values are something that can produce personal ethical dilemmas. Values are what people hold close to their heart and are seen as valuable to them for instance, someone’s cultural beliefs of right and wrong (Oxford, 2014). It’s very important to understand personal ethics and values through critical-reflection (BASW, 2014). Through identifying personal values, ethics and acknowledging the power a social worker holds, you can expose bias views and dominant discourses (Banks, 2006, p.159). Thompson’s PCS Model can help explore any anti-discriminatory and anti-oppressive practices, not just on a personal level, but cultural and social/structural level too (Barbra, 2010, p.12). It’s then possible to reflect and change further professional judgements (Banks, 2006, p.159). Personal values are used to inform every day practice as long as there are within the hcpc. Therefore making the social workers job very complex, because they have to balance their own moral integrity, to society, service users and the agencies they work with in, causing personal ethical dilemmas (Banks, 2006, p.17). To understand how ethical dilemmas arise in social work practice, this essay will apply agency policy and law to a case study. Jack is a 62yr old white man who lives alone in a privately rented flat; Jack has asked if his carer could support him to visit a paid prostitute as part of his assessed care plan; paid for by public funds. The first thing to ascertain is whether any laws or agency policies will be broken. The actual act of visiting a prostitute is not illegal (GOV.UK 2014). The second question to ask is whether local authority procedures allow for the payment of a prostitute. Service users receive direct payments, this can be spent on personal care, social activities, respite care and may vary from one local authority to another (Royal Borough of Greenwich, 2014). So the local authority’s payment would likely cover Jack’s suggestion. The local authority also has a legal duty of care to make sure Jack is not financially exploited (The National Archives, 2014). A social worker has to support Jacks autonomy, even if this puts him in danger (Parrott, 2011, p.90). Jack has become socially isolated because of his disabilities and it is the social workers responsibility to promote social inclusion (hcpc, 2012). In contrast even though it’s not illegal to visit a prostitute there are many laws, professional codes of ethics and personal values against actions involving Jack with prostitution. This is especially relevant to Jack as he has already been warned by the police not to get involved sexually with any underage woman. This causes an ethical dilemma (Banks, 2006, p.12), between promoting Jacks autonomy and protecting Jacks welfare (BASW, 2014). Whilst the local authority’s payment would likely cover Jack’s suggestion, this still could cause an ethical dilemma, between the public generally thinking it’s wrong to use public money visit a prostitute, and the local authority who needs to promote Jacks inclusion in soci ety. Also the actual interaction with the prostitute is beyond the help of a social worker and proposes health risks. Several ethical dilemmas have developed (Banks, 2006, p.14). Whenever a social worker is faced with risk, they would perform a risk assessment (legislation.gov.uk., 2010). The risk assessment would weigh up the consequences for and against supporting Jack. The social worker could use an ethical framework to assist decision making for example, Lowenberg and Dolgoffs, (2005) Ethical Principles Screen, which attempts to put ethical principles in order of importance (Lowenberg and Dolgoffs cited in, Learning Portal, 2013). The social worker would start by examining the risks of not supporting Jack through applying the human rights acts and any other laws. Jacks right to liberty and security would be affected, Article 5; it would also affect his right to the prohibition of discrimination, Article 14 and the right to private and family life, Article 8 (GOV.UK 2014). This would lead to the social worker failing to uphold the Equality Act 2010 (legislation.gov.uk., 2010) and the Local authority would fail in its duty of care (legislation.gov.uk. 2010) . The social worker would then apply professional codes of practice and would be failing in, article five of the hcpc, be aware of the impact of culture, equality and diversity, this is because of Jacks disabilities and a social worker should promote equality for example, equal access to society. The social worker would fail to adhere to article six of the hcpc, also fail to practise in a non-discriminatory manner (hcpc, 2012), this is because the social worker would be withholding funds, not letting him make his own choices, and also limiting his access to society (hcpc, 2012). The social worker would also apply the British Association of Social Workers codes of ethics (BASW, 2014), for example, BASW outline that all social workers should respect human rights and be committed to promoting social justice (BASW 2014). Under BASW the social worker would be compromising values and ethical principles, through failing to uphold and promote human dignity and well-being, respecting the right to self-determination, promoting the right to participation and treating each person as a whole. A social worker is also expected to promote social justice and would be failing in challenging discrimination, distributing resource and recognising diversity (BASW 2014). The social worker would then explore the risks of supporting Jack. For instance this course of action could result in a public moral outcry. This is because there have been several media campaigns, to stop local authorities from using public money for prostitutes (Donnelly, Howie, Leach, 2010). Social workers have a duty to protect the reputation of the profession through the British association of social workers (BASW, 2014). Many of the human rights above are not absolute rights; they are qualified rights and in certain circumstances can be broken, for example when protecting public health or when protecting other people’s human rights. This is evident with Jack potentially taking advantage of a vulnerable person (prostitute) (SHRC, 2014). By applying utilitarianism to the assessment above the theory would suggest finding all the different courses of action available. Second would be to calculate all the positives and negatives that can result from these actions and thirdly this theory suggests to choose the course of action that produces the most benefits and the least damage for all involved (Parrott, 2011, p.54). Supporting Jack would limit for his financial risk, reduced the risk committing an offence, and reduce many of the health risks involved with visiting a prostitute. Also the social worker could make sure the prostitute was making an informed choice (HCPC, 2014). Over all the risk assessment would support Jack, but as mentioned above, the social worker is left with an imperfect answer and the inevitable undesirable effects. But because a risk assessment isn’t an exact science there are additional ways to inform social work practice (Banks, 2006, p.25). The decision to support Jack could compromise the social worker’s personal values causing an ethical dilemma; between personal values and supporting Jack. The social worker could support the idea that Jack should not just seek pleasure. The social worker would be applying virtues ethics (Banks, 2009, pp.38-49), because this ethical theory is more concerned with character not actions. This theory suggests the individual should avoid extremes, this is not to say Jack should not want sex, it just should not come before everything else (Parrott, 2011, p.58). The social worker could also incorporate Kant’s deontological theory. This is an absolutist theory which argues once something is wrong it’s always wrong, for instance, â€Å"you should not take advantage of a vulnerable person† (Parrott, 2011, p.54). This theory is linked to duty. This is called the categorical imperative that indicates we should only conform to an action, when it can be applied to the re st of the world, for instance, if one person lies the rest of the world can lie, this would produce mistrust throughout society. So lying cannot be applied to society universally (Banks, 2006, pp.29-30). In addition there is the concept of reversal, for example, if you were vulnerable would you like someone to take advantage of you? If not, then you shouldn’t do it to anyone else (Parrott, 2011, pp.50-51). The social worker could use the theories above to propose a new course of action based on personal values, in accordance with the law and the professional code of ethics (HCPC, 2014). This course of action would offer a viable alternative. If Jack refused, new ethical dilemmas would arise, similar to the ones discussed above (The National Archives, 2014). This action would limit the risk above and solve most of the ethical dilemmas. For example, one of BASW ethical principles is to identify and develop strengths (BASW, 2014). Jack could be introduced to a wider network of friends, enabling him to find what he needs through clubs, hobbies and dating agencies etc. The consequences of this action is time related, it could take some time for Jack to fulfil his needs. The actual implementation of the action would be governed by utilitarianism, most benefits and the least damage for all involved (Mill, 2004). This paper has shown how ethical dilemmas can arise through agency policy, law, professional ethics and personal values. The paper then applied agency policy and law to a case study to show how ethical dilemmas arise in social work practice, by exposing ethical dilemmas between promoting the welfare of the service user verses promoting the service users right to make their own decisions. The paper proceeded to assess the risk of both courses of action by using theories of ethics through, utilitarianism, deontology, and virtue ethics; this led to explore a more viable solution, through personal values, resulting in a new course of action. The paper can conclude that an ethical dilemma results from conflicting laws, agency policies and personal values, to address these issues a social worker will combine several different ethical theories, with this becoming a mechanical matter for some, informed by personal values for others and sometimes mixture of both.

association of kenyan women writers :: essays research papers

The Association of Media Women in Kenya, AMWIK, is a national media association whose overall concern is to promote and represent interests of women in the media and women in general, particularly in as far as the media portrays them and in their efforts to participate equally in national development. The association was started in 1983 with the prime desire to promote the interests and advancement of women in the media. The organization is apolitical and is run on a voluntary basis by members who also work in various media houses in the country. The membership of sixty, is drawn from women professionals in the print, electronic, advertising and public relations. MISSION To use the media to promote the status of women in general, and to address the concerns of media women in particular, through various projects. OBJECTIVES To organise and unite media women professionals in fellowship and link them with other similar organizations elsewhere. To advance their interests in the profession and promote their understanding of the media profession. To promote the exchange of technical knowledge and professional expertise through the association. To promote training and job opportunities through scholarships, on-the-job guidance, lectures at girls schools and other institutions. To promote understanding of issues through the media as they affect women. OTHER PROGRAMMES Gender Training for Journalists: This has been going on since 1997 and aims at making coverage of women more gender sensitive. Response and interest generated by this training has shown the great need to continue with it. Journalists proposed both training of other journalists and editors so both men and women can get fair coverage. CIDA’s Gender Equity Support project and British Council sponsored this project. Training on Business Writing: This was necessitated by the realisation that women journalists are not involved in the coverage of business/economic issues. The objectives therefore were, to interest women journalists in the issues and encourage them to venture into this area. Women journalists proposed the need to continue the programme in order to equip them further. Nairobi Stock Exchange, NSE and British Council sponsored it. Media Monitoring: The project aims at monitoring how the media covers women in an effort to use the data for advocacy and change. The association has carried out a monitoring exercise in the coverage of violence against women. It intends to make it a regular exercise. It is supported by UN fund for women, UNIFEM.

The Reality of To Kill A Mockingbird Essay -- Harper Lee Kill Mockingb

The Reality of To Kill A Mockingbird The novel, To Kill A Mockingbird, takes place during a racially intense time in history. Harper Lee’s novel was intended to bring a harsh sense of reality to the real world, and demonstrate how it really was during this time in history. This novel is set in Maycomb, Alabama, somewhere during the time period of 1925-1935. Times were hard for the citizens of Maycomb during this period, because of the depression. There are many fictional events in this novel related to non-fictional racial events in history. Leading the list of racial crimes would be hate crimes, such as lynching. Hate crimes are violent acts against people, property, or organizations due to the group to which they belong or identify with. Hate crimes are sadly a tragic part of American history. By far the largest determinant of hate crimes is racial bias, with African Americans the group at greatest risk. (â€Å"Hate Crimes†¦Ã¢â‚¬  1) Lynching was one of the most popular methods of carrying out a hate crime. The term lynching is generally believed to be derived from the name of a Virginia justice of the peace, Charles Lynch, who ordered extralegal punishment for Tory acts during the American Revolution. Frontier settlements in the United States often lacked established law enforcement agencies and, instead, exercised summary justice through vigilantes. Western pioneers punished murder, rape, horse thievery, and other capital crimes by resorting to lynching. (Lynching 1) In the South, during the period 1880 to 1940, there was deep-seated and all-pervading hatred and fear of the Negro. There was an annual average of sixty-two lynchings for the years 1910 to 1919. However, beginning in 1923 lynchings bega... ...ill A Mockingbird. New York: Warner Books, Inc., 1960.

Bill Gates :: William H. Gates III Biography Essays

Bill Gates Bill Gates, cofounder of the Microsoft corporation, holds 30.7 percent of its stock making him one of the richest people in the United States. He was the marketing and sales strategist behind many of Microsoft's software deals. Their software became the industry standard in the early 1980s and has just increased in distribution as the company has grown, so much that the Federal government is suggesting that Microsoft has violated Sherman and Clayton antitrust acts. Bill Gates' first interest in computers began at Lakeside, a private school in Seattle that Gates attended. There he wrote his "first software program when I was thirteen years old. It was for playing tic-tac-toe"(Gates 1). It was at Lakeside that Gates met Paul Allen, who later became cofounder with Gates of Microsoft. There they became friends and "began to mess around with the computer"(Gates 2). Back in the sixties and early seventies computer time was expensive. "This is what drove me to the commercial side of the software business"(Gates 12). Gates, Allen and a few others from Lakeside got entry-level software programming jobs. One of Gates early programs that he likes to brag about was written at this time. It was a program that scheduled classes for students. "I surreptitiously added a few instructions and found myself nearly the only guy in a class full of girls"(Gates 12). In 1972 Intel released their first microprocessor chip: the 8008. Gates attempted to write a version of BASIC (Beginner's All-purpose Symbolic Instruction Code) for the new Intel chip, but the chip did not contain enough transistors to handle it. Gates and Allen found a way to use the 8008 and "started Traf-O-Data, a computer traffic analysis company"(Clayton 452) It worked well however, marketing their new machine proved to be impossible. "No one actually wanted to buy the machine, at least not from a couple teenagers"(Gates 14). Gates and Allen had more less successful endeavors in starting a software company. In 1974 Intel announced their new chip: the 8080. The two college students sent off letters "to all the big computer companies, offering to write them a version of BASIC for the new Intel chip. We got no takers"(Gates 15). While at Harvard, the cool thing to do was to slack off on classes for most of the semester and try and see how well the student could do at the end. Steve Ballmer and Gates "took a tough graduate- level economics course together- Economics 2010.
