Some technologies, such as weapons of mass destruction, are of negative impact. Others, such as medical advances, positively help people to live better or longer, and so very much help traditions ways of life. Surely, few people would seek to preserve such traditions as living in caves. Interestingly, technology can positively contribute to the keeping alive of traditional skills and ways of life. For example, the populations of some islands are too small to have normal schools. Rather than breaking up families by sending children to the mainland, education authorities have been able to use the Internet to deliver schooling online. In addition, the Internet, and modern refrigeration techniques, are being used to keep alive the traditional skills of production salmon, it can now be ordered from, and delivered to, anywhere in the world. In conclusion, without suggesting that all technology is necessarily good, I think it is by no means â€Å"pointless†, in any way, to try to keep traditions alive with technology.

C4T2 Happiness is considered to be very important in life. Why is it difficult to define? What factors are important in achieving happiness? Happiness is very difficult to define, because it means so many different things to different people. While some people link happiness to wealth and material success, others think it lies in emotions and loving personal relationships. Yet others think that spiritual paths, rather than either the material world or relationships with people, are the only way to true happiness. Because people interpret happiness for themselves in so many different ways, it is difficult to give any definition that is true for everyone. However, if there are different kinds of happiness for different individuals then the first step in achieving it would be to have a degree of self-knowledge. A person needs to know who he or she is before being able to know what it is that makes him or her happy. Of cause, factors such as loving relationships, good health, the skills to earn a living and a peaceful environment all contribute to our happiness too. But this does not mean that people without these conditions cannot be happy. Overall, I think an ability to keep clear perspective in life is a more essential factor in achieving happiness. By that I mean an ability to have a clear sense of what is important in our lives (the welfare of our families, the quality of our relationships, making other people happy, etc. ) and a what is not (a problem at work, getting annoyed about trivial things, etc. ). Like self-awareness, this is also very difficult to achieve, but I think these are two factors that may be the most important for achieving happiness. C4T4 In many countries schools have severe problems with student behavior. What do you think are the cause of this? What solutions can you suggest? Poor student behavior seems to be increasingly widespread problem and I think that modern lifestyles are probably responsible for this. ( †¦. ) In many countries, the birth is decreasing so that families are smaller with fewer children. These children are often spoilt , not in terms of love and attention because working parents do not have the time for this, but in more material ways. They are allowed to have whatever they want, regardless of price, and to behave as they please. This means that the children grow up without consideration for others and without any understanding of where their standard of living comes from. ) When they get to school age they have not learnt any self control or discipline. They have less respect for their teachers and refuse to obey school rules in the way that their parents did. Teachers continually complain about this problem and measures should be taken to combat the situation. But I think the solution to the problem lies with the families, who need to be more aware of the future consequences of spoiling their children. If they could raise them to be considerate of others and to be social, responsible individuals, the whole community would benefit. Perhaps parenting classes are needed to help them to do this, and high quality nursery schools could be established that would support families more in terms of raising the next generation. The government should fund this kind of parental support, because this is no longer a problem for individual families, but for society as a whole. C4GTB Some people believe that children should be allowed to stay at home and play until they are six or seven years old. Others believe that it is important for young children to go to school as soon as possible. What do you think are the advantages of attending school from a young age? In many places today, children start primary school at around the age of six or seven. However, because it is more likely now that both parents work, there is little opportunity for children to stay in their own home up to that age. Instead, they will probably go to a nursery school when they are much younger. While some people think this may be damaging to a child’s development, or to a child’s relationship with their parents, in fact there are many advantages to having school experience at a young age. Firstly, a child will learn to interact with a lot of different people and some children learn to communicate very early because of this. They are generally more confident and independent than children who stay at home with their parents and who are not used to strangers or new situations. Such children find their first day at school at the age of six very frightening and this may have a negative effect on how they learn. Another advantage of going to school at an early age is that children develop faster socially. They make friends and learn how to get on with other children of a similar age. This is often not possible at home because they are the only children, or because their brothers or sisters are older or younger. So overall, I believe that, attending school from a young age is good for most children. They still spend plenty of time at home with their parents, so they can benefit from both environments. C5T2 In some countries young people are encouraged to work or travel for a year between finishing high school and starting university studies. Discuss the advantages and disadvantages for young people to do this. It is quite common these days for young people in many countries to have a break from studying after graduating from high school. This trend is not restricted to rich students who have the money to travel, but is also evident among poorer students who choose to work and become economically independent for a period of time. The reasons for this trend may involve the recognition that a young adult who passes directly from school to university is rather restricted in terms of general knowledge and experience of the world. By contrast, those who have spent some time earning a living or traveling to other places have a broader view of life and better personal resources to draw on. (Furthermore,) They tend to be more independent, which is a very important factor in academic study and research, as well as giving them an advantage in terms of coping with the challenges of student life. However, there are certainly dangers/risks in taking time off at that important age. Young adults may end up never returning to their studies or finding it difficult to readapt to an academic environment. They may think that it is better to continue in a particular job, or to do something completely different from a university course. But overall, I think this is less likely today, when academic qualifications are essential for getting a reasonable career. My view is that young people should be encouraged to broaden their horizons. That is the best way for them to get a clear perspective of what they are hoping to do with their lives and why. Students with such a perspective usually tends to be the most effective and motivated ones and taking a year off may be the best way to gain this. C5T4 Research indicates that the characteristics we are born with have much more influence on our personality and development than any experiences we may have in our life. Which do you consider to be the major influence? Today the way we consider human psychology and mental development is heavily influenced by the genetic sciences. We now understand the importance of inherited characteristics more than ever before. Yet we are still unable to decide whether an individuals personality and development are more influenced by genetics factors (nature) or by the environment (nurture). Research, relating to identical twins, has highlighted how significant inherited characteristics can be for an individuals life. But whether these characteristics are able to develop within the personality of an individual surely depends on whether the circumstances allow such a development. It seems that the experiences we have in life are so unpredictable and so powerful, that they can boost or over-ride other influences, and there seems to be plenty of research findings to confirm this. My own view is that there is no one major influence in a persons life. Instead, the traits we inherit from our parents and the situations and experiences that we encounter in life are constantly interacting. It is the interaction of the two that shapes a persons personality and dictates how that personality develops. If this were not true, then we would be able to predict the behaviour and character of a person from the moment they were born. In conclusion, I do not think that either nature or nurture is the major influence on a person, but that both have powerful effects. How these factors interact is still unknown today and they remain largely unpredictable in a persons life. C5GTB Nowadays we are producing more and more rubbish. Why do you think this is happening? What can governments do to help reduce the amount of rubbish produced? I think it is true that in almost every country today each household and family produces a large amount of waste every week. Most of this rubbish comes from the packaging from the things we buy, such as processed food. But even if we buy fresh food without packaging, we still produce rubbish from the plastic bags used everywhere to carry shopping home. The reason why we have so much packaging is that we consume so much more on a daily basis than families did in the past. Convenience is also very important in modern life, so we buy packaged or canned food that can be transported from long distances and stored until we need it, first in the supermarket, and then at home. However, the amount of waste produced is also a result of our tendency to use something once and throw it away. We forget that even the cheapest plastic bag has used up valuable resources and energy to produce. We also forget that it is a source of pollution and difficult to dispose of. I think, therefore, that governments need to raise this awareness in the general public. Children can be educated about environmental issues at school, but adults need to take action. Governments can encourage such action by putting taxes on packaging, such as plastic bags, by providing recycling services and by fining households and shops that do not attempt to recycle their waste. With the political will, such measures could really reduce the amount of rubbish we produce. Certainly nobody wants to see our resources used up and our planet poisoned by waste. C6T2 Successful sports professionals can earn a great deal of more money than people in other important professionals. Some people think this is fully justified while others think it is unfair. Discuss both these views and give your own opinion. As a result of constant media attention, sports professionals in my country have become stars and celebrities, and those at the top are paid huge salaries. Just like movie stars, they live extravagant lifestyles with huge houses and cars. Many people find their rewards unfair, especially when comparing these super salaries with those of top surgeons or research scientists, or even leading politicians who have the responsibility of governing the country. However, sports salaries are not determined by considering the contribution to society a person makes, or the level of responsibility he or she holds. Instead, they reflect the public popularity of sport in general and the level of public support that successful stars can generate. So the notion of ‘fairness’ is not the issue. Those who feel that sports stars’ salaries are justified might argue that the number of professionals with real talent are very few, and the money is a recognition of the skills and dedication a person needs to be successful. Competition is constant and a player is tested every time they perform in their relatively short career. The pressure from the media is intense and there is little privacy out of the spotlight. So all of these factors may justify the huge earnings. Personally, I think that the amount of money such sports stars make is more justified than the huge earnings of movie stars, but at the same time, it indicates that our society places more value on sport than on more essential professions and achievements. C6T4 Some people prefer to spend their lives doing the same things and avoiding change. Others, however, think that change is always a good thing. Discuss both these views and give your own opinion. Over the last half century the pace of change in the life of human beings has increased beyond our wildest expectations. This has been driven by technological and scientific breakthroughs that are changing the whole way we view the world on an almost daily basis. This means that change is not always a personal option, but an inescapable fact of life, and we need to constantly adapt to keep pace with it. Those people who believe they have achieved some security by doing the same, familiar things are living in denial. Even when people believe they are resisting change themselves, they cannot stop the world around them from changing. Sooner or later they will find that the familiar jobs no longer exist, or that the ‘safe’ patterns of behavior are no longer appropriate. However, reaching the conclusion that change is inevitable is not the same as assuming that ‘change is always for the better’. Unfortunately, it is not always the case that new things are promoted because they have good impacts for the majority of people. A lot of innovations are made with the aim of making money for a few. This is because it is the rich and powerful people in our society who are able to impose changes (such as in working conditions or property developments) that are in their own interests. In conclusion, I would say that change can be stimulating and energizing for individuals when they pursue it themselves, but that all change, including that which is imposed on people, does not necessarily have good outcomes. C6GTB Using a computer every day can have more negative than positive effects on young children. Do you agree or disagree? I tend to agree that young children can be negatively affected by too much time spent on the computer every day. This is partly / primarily because sitting in front of a screen for too long can be damaging to both the eyes and the physical posture of young child, regardless of what they are using the computer for. However, the main concern is about the type of computer activities that attract children. These are often electronic games that tend to be very intense and rather violent. The player is usually the â€Å"hero† of the game and too much exposure can encourage children to be self-centered and insensitive to others. Even when children use a computer for other purposes, such as getting information or emailing friends, it is no substitute for human interaction. Spending time with other children and sharing non-virtual experiences is an important part of a children’s development that cannot be provided by a computer. In spite of this, the obvious benefits of computer skills for young children cannot be denied. Their adult world will be changing constantly in terms of technology and the Internet is the key to all the knowledge and information available in the world today. Therefore it is important that children learn t an early age to use the equipment enthusiastically and with confidence as they will need these skills throughout their studies and working lives. I think the main point is to make sure the young children do not overuse computers. Parents must ensure that their children learn to enjoy other kinds of activity and not simply sit at home, learning to live in a virtual world. C7T1 I t is generally believed that some people are born with certain talents, for instance for sport or music, and others are not. However, it is sometimes claimed that any child can be taught to become a good sports person or musician. Discuss both these views and give your own opinion. The relative importance of natural talent and training is a frequent topic of discussion when people try to explain different levels of ability in, for example, sport, art or music. Obviously, education systems are based on the belief that all children can effectively be taught to acquire different skills, including those associated with sport, art or music. So from our won school experience, we can find plenty of evidence to support the view that a child can acquire these skills with continued teaching and guided practice. However, some people believe that innate talent is what differentiates a person who has been trained to play a sport or an instrument, from those who become good players. In other words, there is more to the skill than a good learned technique, and this extra talent cannot be taught, no matter how good the teacher or how frequently a child practices. I personally think that some people do have talents that are probably inherited via their genes. Such talents can give individuals a facility for certain skills that allow them to excel, while more hard-working students never manage to reach a comparable level. But, as with all questions of nature versus nurture, they are not mutually exclusive. Good musicians or artists and exceptional sports stars have probably succeeded because of both good training and natural talent. Without the natural talent, continuous training would be neither attractive nor productive, and without the training, the children would not learn how to exploit and develop their talent. In conclusion, I agree that any child can be taught particular skills, but to be really good in areas such as music, art or sport, then some natural talent is required. 282words) C7T3 At most people spend a major part of their adult life at work, job satisfaction is an important element of individual wellbeing. What factors contribute to job satisfaction? How realistic is the expectation of job satisfaction for all workers? Nowadays many adults have full-time jobs and the proportion of their lives spent doing such jobs is very high. So feelings about one’s job must reflect how an i ndividual feels about his or her life as whole, and because of this, job satisfaction is indeed very important for the wellbeing of that person. Employees get job satisfaction in a number of ways. Firstly, a person needs to feel that they are doing valued and valuable work, so positive feedback from superiors is very important in this respect. A sense of fulfillment is also encouraged if a worker feels the job is worth doing because it contributes to the society or the economy as a whole. Secondly, when someone feels they are improving or developing their skills through training opportunities, for example, then there is as sense of progression and purpose that rewards a worker. The sense of belonging to a team or a working community also contributes to job satisfaction because colleagues help each other to enjoy their working lives. Satisfaction is also increased by a sense of responsibility for and loyalty to a team. Of course not everyone enjoys heir work. Hard economic realities mean that many people have little choice in the kind of job they can get. In some cases an employee is working in a job that suits neither their skills nor their personality. Some jobs are repetitive and boring, and labour relations may be poor and lead to resentment and insecurity rather than to job satisfaction. However, even though it is unlikely that all workers do feel happy in their work, I think it is not unrealistic to promote more job satisfaction in any job. If the factors identified above are implemented, then any hob can be improved and more workers can feel greater degrees of job satisfaction. (303) C7GTB Some people feel that entertainers (e. g. film stars, pop musicians or sports stars) are paid too much money. Do you agree or disagree? Which other types of job should be highly paid? I agree with the view that stars in the entertainment business are usually over paid. This is true whether we are considering stars of film, sport or popular music, and it often seems that the amount of money they are able to earn in as short time cannot possibly be justified by the amount of work they do. However, it is also true that it is only those who reach the very top of their profession who can get these huge salaries. So the size of salary that stars expect is closely linked to the competition they have to overcome in order to reach success. They are, in effect, rare talents. Furthermore, the majority of stars do not hold their top positions long. Sport stars and pop stars, for example, are soon replaced by the next younger, more energetic, generation, while the good looks of most film stars quickly fade. So this relatively short working life may be some justification for the very high pay. Unfortunately, professionals from other fields, who make a much greater contribution to human society, are paid so much less that it is hard to disagree with the statement. Teachers, nurses, laboratory researchers etc. are never listed among the best-paid professionals, yet they are more important to our well-being and our future than the stars who earn their fortunes so quickly. In conclusion, I think there may be some reasons why entertainment stars earn high salaries but overall I agree that they are overpaid. The gaps between their earnings and those of people who work less selfishly for the good of society cannot be justified. Such professionals should be much better appreciated and better paid. (279)

Frost, Robert Essays - Poetry, Literature, American Poetry

Frost, Robert Essays - Poetry, Literature, American Poetry Frost, Robert Robert Frost, perhaps the greatest American poet of the twentieth century, has brought himself great recognition. Many critics have tried to find a faulty side to his writing, but they have had a difficult time because his writing romanticizes the rural simplicity that he loved while probing into the mysteries of the universe (Estep 2). Three areas of criticism covered are: a speaker's decision in choosing, a poem broken down into three sections, and Frost's use of metaphors and style in his writing. Born in San Francisco, but raised in New England, many of Robert Frost's poems are representations of his experiences in the northeastern parts of America. He was unsuccessful in college never earning his degree, and for several years he supported his family by tending to a farm his grandfather bought for him. In his spare time, Frost would read and write anything and everything. Discouraged by his unsuccessful life as a poet, he packed up his bags and moved to England. He continued writing and published his first two books of poetry, which would gain him the recognition in America he had been in search of (ExpLit 1). One of Frost's most famous poems is The Road Not Taken. This poem is about someone who comes to a fork in a path. One path is well beaten and treaded, while the other is less traveled and more difficult. Is the traveler happy with the decision he has made to take the road less traveled? Many critics think he may have had second thoughts. Magill's Survey of American Literature states that there are many contradictions throughout the poem, He seems to contradict his own judgment. The poet appears to imply that the decision is based on evidence that is, or comes close to being an allusion (Magill 64).The tone of the stanza and the title of the poem suggest that the traveler may be regretting his choice because by making a choice to do one thing you have to give up the opportunity to do another (Magill 74). I kept the first for another day! I shall be telling this with a sigh. Discovering Authors Modules agrees with other critics. Is he truly happy with his choice? The traveler doesn't ever directly say he was happy with his choice, so is he satisfied? In the poem it states, and that has made all the difference, but has it made all the difference in a positive way (DAM 2). Frost also probes one of the great mysteries of life: the ability to choose and the consequences of choosing (DAM 2). The Literary Caf also has similar ideas on the poem. After the traveler has chosen which path to follow, he still yearns to travel both paths, saying that he'll keep the first for another day. But, then he realizes that there is no return to the other path and that the final decision has been made. At the end of the poem the traveler sighs, but is he sighing because he is satisfied with his decision or because he may regret something about choosing the path that he did (LitCaf 1). Another famous poem by Robert Frost is Birches. It is a poem about the way the branches on a birch tree bend in the winter. Many critics think the poem is divided into three basic parts. An Interpretation of Frost's Birches thinks the three parts are the scientific explanation of the appearance of the birches, Frost's boyhood fantasy about their appearance, and his present day interpretation of their appearance. The first section is of the natural ways a branch would bend and crack because of weather. Loaded with ice a sunny winter morning after a rain. The second is more of how the branches would bend because of a little boy swinging on them. By riding them down over and over again until he took the stiffness out of them. Then in the third section Frost expresses how the tree reaches toward heaven and brings back memories of his childhood. And climb back branches up a snow-white trunk Toward heaven. Magill has also noticed the three sections but in a slightly different format, saying, It can be separated into three almost equal parts: the observation

Glider 1 Assignment Example | Topics and Well Written Essays - 1250 words

Glider 1 - Assignment Example This paper declares that a glider usually has got 3 forces acting on it while in flight in comparison with 4 forces that normally act on an aircraft that is powered. Both kinds of aircrafts are all subjected to drag, weight, and lift forces. For the powered craft, there is the engine thrust that opposes the drag; however, there is no thrust for glider. A glider must generate lift so as to oppose its own weight for it to fly. For lift to be generated, a glider ought to move via the air. A glider’s motion via the air produces drag. In the case of an aircraft that is powered, the drag is opposed by the engine’s thrust; however, the glider lacks an engine to produce thrust. With nothing to oppose the drag, a glider will rapidly slow down till it can no longer produce adequate lift to resist its weight, and falls down to the ground finally. This report makes a conclusion that it does not matter the length of the moment arm is to be employed. This is because both short as well as long moment arms are endowed with their advantages as well as disadvantages respectively. For instance, a disturbing force normally has a superior impact on an arm that is short as compared to one that is long. A long moment is slow to respond to stabilizing forces and thus loses its earlier advantage to a short one. However, on throwing, a glider with short moment arm recovers more rapidly due to stabilizing properties, whereas a longer moment ship usually attains more height before it finally recovers fully, going into a straight glide.

Quantitative Data Analysis- SPSS Essay Example | Topics and Well Written Essays - 2000 words

Quantitative Data Analysis- SPSS - Essay Example Ethnicity has its impacts felt in many aspects. In education, ones ethnic group determines a lot whether the individual will have a future or not. In some ethnic groups, education is relegated to a far position when one rates other things (Zeichner, K., & Schulte, A. 2001 p. 251). Education in such cases is viewed as being not important at all. According to Flores, G et al. (1999), despite its importance as a hinge to all and every aspect in life, it is viewed by some ethnicities as passage which is not a must for one to undergo. In some African societies for example, education is a thing un-heard of and parents don’t consider taking their children to school. According to Skaggs, M. C. (2001), some ethnic communities have the will to have their children in school, however, the aspect of little finances which they get hinder them (p. 41). Skaggs argues that, if all ethnic communities in diverse countries are given equal opportunities to that accorded their peers from other ethnic communities, then the probability that, they will also attain some grades in very high. To him, lack of proper representation in education institutions of middle and higher learning is not because of their liking but because of the situations they find them selves in (p. 48). The marital status of a parent is another aspect which leads to low education levels. The institution of marriage is one of the conducive environments where education can thrive well. To Stephens, J. (1999), minorities in the US and other developed countries suffer a lot since most of their parents are single parents and lack the will to educate their children (p. 31). To Stephens, a single parent faces the problem of educating since he/she is the sole breadwinner and with the cost of education soaring high, the possibility of educating is dim (p. 33). To Su, Z. (1996), the level of one’s education determines what he/she will earn after the completion of education. According to him,

How would you incorporate the concepts from the nursing theory to the Essay

How would you incorporate the concepts from the nursing theory to the nursing curriculum - Essay Example The use of overt and formal ways of teaching caring requires the combination of classroom knowledge and the clinical application of caring. According to Cartwright, Davson-Galle and Holden, the nursing curriculum is based upon the predominant philosophy of existentialism (Cartwright, Davson-Galle, & Holden, 1992). It would be essential to incorporate moral development lessons in the initial stages of nursing programs. The incorporation of moral development education encourages accountability, professional and personal autonomy, and the nurses’ ethical decisions in the workplace (Beck, 2001). The consideration requires the utilization of Christian values necessary for building a moral philosophy in nursing practice. The goal is to ensure that nurses honor the human aspects of nursing, patients’ subjective experiences, and their inner life (Watson, 2001). It would be vital to integrate nursing education with liberal education in humanities, arts and sciences. Such an approach enables nursing students to obtain knowledge regarding social, economic, and political issues. They use the knowledge to analyze professional and societal problems, develop critical thinking skills, and appreciate the character of their professions (Beck, 2001). The aforementioned considerations support concepts and nursing theories essential for the translation of a nurse’s affective characteristics into appropriate, compassionate, and sensitive aspects of

Effects of Polychlorinated Biphenyl (PCB)

Effects of Polychlorinated Biphenyl (PCB) Polychlorinated Biphenyl (PCB) is a persistent organochlorine that has 209 congeners and can be divided into two categories, dioxin-like and non-dioxin-like. Although these two categories have different structures and toxicological profiles, both have an adverse impact on the human health [1]. Since PCB is a stable chemical and can withstand extreme temperature and pressure, it was heavily used back in 1929 for electrical equipment [2]. While the production of PCB was ceased in 1977, traces of PCB can still be observed on the Great Lakes for it was once used as a disposal site along with the possibility of accidental leaks. From lakes, it can move into different waterways and later be passed on by organisms. Long-range-transport of PCB vapours through air currents also functions as a dispersion mechanism in the ambient air [3] [4] [5]. Anyone can be susceptible depending on the rate of the exposure and the amount of stressor a person had been exposed to. PCB can enter the system thro ugh ingestion, inhalation and dermal contact, all of which can essentially bioaccumulate and inhibit the bodys natural processes in the event that the receptor had exceeded the threshold. PCB has been linked to endocrine dysfunction, reproduction deficiencies, chloracne, liver damage and kidney cancer [6]. Recognizing credible sources is a key factor in toxicity assessment. This allows the reader to acquire more information about the chemical of concern and make an informed decision. Some credible sources are listed below: Agency for Toxic Substances and Disease Registry European Chemicals Agency Health Canada United States Environmental Protection Agency World Health Organization     Ã‚   3.1. What happens when PCB enters the body? Humans absorb PCB through inhalation, ingestion and dermal contact. On bioassays conducted, it was observed that animals absorbed PCB well when administered orally and less absorbed when exposed through dermal contact. While inhalation is an accounted pathway for PCB, there is inadequate data to identify the absorption rates. Upon absorption, PCB is dispersed into the lipophilic cell membranes in the gastrointestinal tract. It then circulates into the blood vessels and enters the lymphatic system. Due to the lipophilic nature of PCB molecules, it is readily absorbed by the fatty tissue. In autopsies conducted, the liver, adipose tissue, brain and skin usually contains higher concentrations of PCB. Elimination of PCB can be through excretion of feces, urine and breast milk [7]. When exposed to PCB, symptoms include severe acne, swelling of the upper eyelids, discolouring of the nails and skin, numbness in arms and/or legs, weakness, muscle spasms, chronic bronchitis, and neurological complications [6]. 3.2. Acute and Chronic Effects PCB exhibits both acute and chronic effects. Although it demonstrates low potential in producing acute effects, however, due to the risk it poses in human health in the long-term, it is still deemed to be a public health concern. Skin lesions particularly chloracne has been observed during occupational exposures. Nausea and headaches were also reported yet this could be primarily due to the solvents in the PCB mixtures. Subsequently, long-term exposure to PCB has been linked to reproductive deficiencies, liver damage and kidney cancer [8]. 3.3. Threshold vs Non-threshold PCB has shown evident carcinogenicity in animals and therefore is considered to be non-threshold substance by USEPA. The data for human carcinogenicity for PCB mixture is deemed to be inadequate but suggestive. Essentially, PCB can also be classified as threshold substance because of its non-cancer potential in lower concentrations and short-term exposure [9].   3.4. What effects does it have? Carcinogenic US EPA labeled PCB as Group B2, a probable human carcinogen. This was based on the experiment of exposure of rats to several mixtures of PCB that are often found in the environment [10]. On a study published in 1976, occupational exposure to PCB increased the mortality from cancer. However, the outcomes were mixed since the study only found limited deaths and incomplete exposure assessments [7]. Mutagenicity There were insufficient data involving the mutagenicity of PCB [7]. A bacterial test which distinguishes chemical mutation effects was conducted on PCB. Although PCB demonstrated negative results, this was not uncommon since PCB has complex compounds and pathways [11]. Reproductive Toxicity Oral administration of PCB on animals has displayed toxicity effects but dermal and inhalation exposure were not available. Exposure of rats and mice to high doses of PCB had produced several effects. The effects documented were decreased conception rate, pro-longed menstruation, decreased litter size and reduced sperm count. Rats and mice that were exposed to PCB while lactation suggested long-lasting adverse effect on the offspring. On another study, PCB is also associated to estrogen-related effects [7]. 4.1. Bioassay Overview The slope factor of PCB was based upon the studies conducted by Brunner et al. (1996) and Norback and Weltman (1985). A group of male and female Sprague-Dawley rats were exposed to different Aroclor. Groups of 50 female or male rats were orally administered with 25, 50 or 100 ppm Aroclor 1260 or 1254; 50 or 100 ppm Arcolor 1242; or 50, 100, or 200 ppm Aroclor 1016. At 104 weeks, the rats were killed. Liver adenomas or carcinomas were discovered in all female rats for all Aroclors and male rats for Aroclor 1260. While thyroid gland follicular cell carcinoma was evident on male rats, female rats also exhibited mammary tumors at a later age. On another study, male and female Sprague-Dawley rats were exposed to 0 or 100ppm of Aroclor 1260 for 16 months and subsequently reduced to 50 ppm for another 8 months. Tests were executed in different months to understand the changes in the structure of the rats. The intensity of the damage on the liver increases as you progress through the months. On the 29th month, most of the female rats displayed carcinoma and neoplastic nodules whereas male rats had lesser incidence [10] . 4.2. Published Benchmark A tiered approach was used by USEPA to determine the cancer potency of PCB. Upper-bounds provide precision while central-estimates are appropriate for estimating risks. Potency values are dependent on the exposure pathway. For exposure pathways with increased risks, we use High Risk and Persistence. Exposure pathways that decrease risk are appropriate on Low Risk and Persistence. Lowest Risk and Persistence is developed from Aroclor 2016, therefore it is appropriate for congeners with more than for chlorine. The slope factor can be generated by dividing 0.10 by ED10 (Estimated dose associated with 10% increased incidence, in mg/kg-d) [12]. High Risk and Persistence Low Risk and Persistence Lowest Risk and Persistence Upper-Bound Slope Factor 2.0 per (mg/kg)/day 0.4 per (mg/kg)/day 0.07 per (mg/kg)/day Central-Estimate Slope Factor 1.0 per (mg/kg)/day 0.3 per (mg/kg)/day 0.04 per (mg/kg)/day Criteria for use Food chain exposure Sediment or soil ingestion Dust or aerosol inhalation Dermal exposure, if an absorption factor has been applied Presence of dioxin-like, tumor-promoting, or persistent congeners Early-life exposure (all pathways and mixtures) Ingestion of water-soluble congeners Inhalation of evaporated congeners Dermal exposure, if no absorption factor has been applied Congener or isomer analyses verify that congeners with more than 4 chlorines comprise less than 1/2% of total PCBs. Figure 1 Tiers of Human Slope Factors For Environmental PCB [13]. Uncertainty Factors It is important to know that not everyone responds equally to a given chemical. Populations with higher sensitivity may be associated with increased risks. Also, the genetics and lifestyle of a person must be accounted as this pose potential change on the dose-response trend. Furthermore, it is essential to recognize that the mixtures of PCB tested in animals are Aroclor mixtures which have been pre-determined and not environmental mixtures that had bioaccumulated which are generally more potent [10]. Figure 1 shows that the slope factor is dependent upon the exposure pathway. Although these are just estimates, scientists have dedicated their time to conduct bioassays where we can extrapolate the data to potentially understand the dose that can harm humans. However, it is also crucial to know that environmental processes can alter the PCB concentrations, therefore it is best to be educated on how you can be exposed to PCB and how you can avoid this. To improve the assessment, studies concerning sensitive population should be further considered and assessed. Since PCB concentrations are altered in the environment, animals or humans that are already exposed could be used to investigate and compare the differences with the experiments done in the laboratory. In addition, it was not mentioned why rats were chosen as experiment parameters, analyzing parameters used could help readers discern why rats are relevant for the study. [1] P. Heikkinen, . L. T.

Gender Roles and Stereotypes Explored in Judy Manns The Difference and

Gender Roles and Stereotypes Explored in Judy Mann's The The Difference: Growing Up Female in America and Bernard Lefkowitz's Our Guys Gender stereotypes are common in the United States today, even though many men and women have been working hard to defeat it. The task is made difficult however, when society in general implants the idea of gender roles into the mind of a child. Two authors, Judy Mann of The Difference and Bernard Lefkowitz of Our Guys face the issue of gender roles and stereotypes, and how they affect our lives today. Our Guys focuses on the way that young boys are brought up by society by telling the true story of a group of Glen Ridge, New Jersey teenage boys who sexually assaulted a young retarded girl. Neither the boys nor the townspeople saw what they did as wrong, and tried everything in their power to get them acquitted. They were however, fighting for the wrong cause. It was the boys’ parents and society itself that gave the teens the illusion that they, as males, should be given free range and power over those weaker than themselves. From the time these boys in question were born, their parents and their environment (including the composition of their nuclear families, i.e. ratio of males to females) made them kings. They were privileged teens and the fact that they were male made them even more so. All the ‘jocks’ involved were angels in their mothers’ eyes, who was in most cases, the only female influence in their lives and not a very good one at that (1 35). The Glen Ridge boys, affectionately known to their peers as "our guys", were brought up as stereotypical boys, worsened by the "boys will be boys" attitude adopted by their parents, teachers and neighbors (Lefkowitz, 73). This ... ...only accepted stereotypes are not based in reality at all, and that these stereotypes are harmful to everyone, not just the victims of being typecast. This conclusion is correct in all senses. Judy Mann’s book shows that the only real difference between men and women are their reproductive organs (24). Many professionals support this fact, but not society. Bernard Lefkowitz’s retelling of what happened to the young girl in Glen Ridge, New Jersey shows that believing that women are inferior can have terrifying repercussions. Society’s perception of people and the practice of labeling based on gender must be eliminated in order for women and men to live equally. These books simply help to make more people aware of the problem, which is only part of the solution. Works Cited Mann, Judy. The Difference: Growing up Female in America. New York: Warner, 1994.

Analysis of “The Seduction”

The Seduction is a poem written by Eileen McCauley. It is about a young and vulnerable sixteen year old girl whose head is filled with thoughts about love and romance portrayed in teenage magazines. These fake ideals lead her to believe that a boy, whom she meets at a party, truly loves her, when really he is just getting her drunk so her resistance will be lower and she will give in to what he wants from her: sex. Three months later she discovers that she is pregnant, she blames teen magazines for filling her head with false ideal of romance.In the very first verse of the poem, the writer introduces the scene of the poem, â€Å"He led her to the quiet bricks of the Birkenhead docks, far past the silver stream of the traffic throughout the city, far from the blind windows of the tower blocks. † This tells us of how there is nobody around to witness what they do. It becomes clear to the reader at the beginning of the poem that he is trying to get her drunk, as when the poet is describing the moment they met, one of the first things he is doing is buying her drinks. We also see this at a later stage when they are at the docks. He handed her the vodka† – this quote proves that he is making an effort to try and get the girl drunk because the alcohol will affect her decisions and causes her to agree to things she normally wouldn’t. Also In the second verse, the boy mutters â€Å"little slag. †This shows us that the boy thinks very little of the girl and lacks respect for women. We then discover that the girl is under some sort of spell because as he talked about football, â€Å"she had nodded, quite enchanted† this shows us that she is keen to listen to what he has to say. With his eyes as blue as iodine† – the use of the word ‘iodine’ used to describe his eyes suggests that there is something dark about him as iodine is a dark blue/black acid. In the fifth stanza, the boy mentions that he goes down to the river when he should be in school or having dinner with â€Å"a bag of shimmering paint thinner. † This shows us that he doesn’t spend much, if any time in school and that he uses the paint thinner as a drug. If the girl was sober, this would be a clear sign to stay away from him but he has lowered her resistance by getting her drunk.We can tell that the girl is a young teenager who enjoys school and wants to do well as she talks about her education in an enthusiastic way. The beginning of the sixth stanza makes us realise how precocious this girl really is, â€Å"so she followed him there, all high white shoes, all wide blue eyes and bottles of vodka. † This sentence shows us that she is trying to grow up too fast because this is what the magazines made her believe was the right thing to do. The poets then says â€Å"then when he swiftly contrived to kiss her, his kiss was scented by Listerine† this tells us that he was prepared for what he wanted to do.Even though we realise that the girl is very precocious, we discover how immature she actually is as it says â€Å"she stifled a giggle, reminded of numerous stories from teenage magazines† this also tells us that she has read about moments like these but hasn’t experienced them until now. The next stanza begins with â€Å"When she discovers she was three months gone† this shows us that the poet has used euphemism to emphasise the harsh reality of what this girl is going through. And she ripped up all her My Guy and Jackie photo comics† I think she does this because the magazines are what filled her head with false ideals about what romance and love should be like. She is angry that the media lied to her and that’s why she ripped then all up. The next stanza then says â€Å"and on that day, she broke the heels of her high white shoes and flung them at the wall† she does this because they were the shoes she wore on the night of the part y to make her look and feel older.She doesn’t want them anymore as she realises that she doesn’t want to be older because of the massive problem that she is faced with. The eighth stanza is mainly telling us about what the magazines have told this girl about what her life should be like â€Å"full of glitzy fashion features and stories of love and romance, where strangers could lead you to bright new worlds, and how would you know if you never took a chance? † This reflects on the consequences of what she did last night and how the media made her think she should take a chance.The ninth stanza says â€Å"full of fresh fruit diets† this shows us that she won’t be able to try out any of these diets as she is now three months pregnant. â€Å"Now with a softly rounded belly, she was sickened every morning by stupid stupid promises, only tacitly made† This shows us that she is reminded every morning of the huge mistake that she made that night. A lso the word â€Å"stupid† is repeated twice, maybe to emphasise that she regrets her actions a lot.The poet then states in the ten and eleventh stanza the things that the girl would be missing out on. This reminds us that the girl is so young and is faced with problems that she shouldn’t have to face at that age. â€Å"With a glass of lager-shandy, on a carpeted floor† this sentence makes the fantasy of romance seem far better than what is really is. The use of the words â€Å"carpeted floor† makes it seem luxurious and â€Å"lager shandy† makes it seem much more innocent as it is a lighter drink than the vodka she drunk the night of the party.In the last few stanzas, the poet states things that the girl would rather do than become pregnant â€Å"But then again, better to be smoking scented drugs or festering, invisibly unemployed† This shows us that she is almost going into a state of depression. She then describes being ‘stuck in a feminine void’, which basically means accidentally becoming pregnant. In the very last stanza, it becomes clear to us that she is very ashamed of herself because the poet says â€Å"better to turn away, move away, fade away, than to have the neighbours whisper ‘you always looked the type. ’

The History of Singapores Economic Development

The History of Singapores Economic Development In the 1960s, the city-state of Singapore was an undeveloped country with a GDP per capita of less than U.S. $320. Today, it is one of the worlds fastest-growing economies. Its GDP per capita has risen to an incredible U.S. $60,000, making it one of the strongest economies in the world. For a small country with few natural resources, Singapores economic ascension is nothing short of remarkable. By embracing globalization, free-market capitalism, education, and pragmatic policies, the country has been able to overcome its geographic disadvantages and become a leader in global commerce. Independence For over 100 years, Singapore was under British control. But when the British failed to protect the colony from the Japanese during World War II, it sparked a strong anti-colonial and nationalist sentiment that subsequently led to Singapores independence. On August 31, 1963, Singapore seceded from the British crown and merged with Malaysia to form the Federation of Malaysia. The two years Singapore spent as part of Malaysia were filled with social strife, as the two sides struggled to assimilate with one another ethnically. Street riots and violence became very common. The Chinese in Singapore outnumbered the Malay three-to-one. The Malay politicians in Kuala Lumpur feared their heritage and political ideologies were being threatened by the growing Chinese population throughout the island and peninsula. Therefore, as a way of ensuring a Malay majority within Malaysia proper and to limit the influence of communism, the Malaysian parliament voted to expel Singapore from Malaysia. Singapore gained formal independence on August 9, 1965, with Yusof bin Ishak serving as its first president and the highly influential Lee Kuan Yew as its prime minister. After independence, Singapore continued to experience problems. Much of the city-states three million people were unemployed. More than two-thirds of its population was living in slums and squatter settlements on the citys fringe. The territory was sandwiched between two large and unfriendly states in Malaysia and Indonesia. Singapore lacked natural resources, sanitation, proper infrastructure, and adequate water supply. In order to stimulate development, Lee sought international assistance, but his pleas went unanswered, leaving Singapore to fend for itself. Globalization During colonial times, Singapores economy was centered on entrepà ´t trade. But this economic activity offered little prospect for job expansion in the post-colonial period. The withdrawal of the British further aggravated the unemployment situation. The most feasible solution to Singapores economic and unemployment woes was to embark on a comprehensive program of industrialization, with a focus on labor-intensive industries. Unfortunately, Singapore had no industrial tradition. The majority of its working population was in trade and services. Therefore, they had no expertise or easily adaptable skills. Moreover, without a hinterland and neighbors who would trade with it, Singapore was forced to look for opportunities well beyond its borders to spearhead its industrial development. Pressured to find work for their people, the leaders of Singapore began to experiment with globalization. Influenced by Israels ability to leap over its Arab neighbors (who boycotted Israel) and trade with Europe and America, Lee and his colleagues knew they had to connect with the developed world and convince multinational corporations to manufacture in Singapore. In order to attract investors, Singapore had to create an environment that was safe, corruption-free, and low in taxation. To make this feasible, the citizens of the country had to suspend a large measure of their freedom in place of a more autocratic government. Anyone caught conducting narcotic trade or intensive corruption would be met with the death penalty. Lees People Action Party (PAP) repressed all independent labor unions and consolidated what remained into a single umbrella group called the National Trade Union Congress (NTUC), which the party directly controlled. Individuals who threatened national, political, or corporate unity were quickly jailed without much due process. The countrys draconian, but business-friendly laws became very appealing to international investors. In contrast to its neighbors, where political and economic climates were unpredictable, Singapore was very stable. Moreover, with its advantageous location and established port system, Singapore was an i deal place to manufacture goods. By 1972, just seven years after independence, one-quarter of Singapores manufacturing firms were either foreign-owned or joint-venture companies, and both the United States and Japan were major investors. As a result of Singapores steady climate, favorable investment conditions and the rapid expansion of the world economy from 1965 to 1972, the countrys Gross Domestic Product (GDP) experienced annual double-digit growth. As foreign investment money poured in, Singapore began focusing on developing its human resources in addition to its infrastructure. The country set up many technical schools and paid international corporations to train their unskilled workers in information technology, petrochemicals, and electronics. For those who could not get industrial jobs, the government enrolled them in labor-intensive un-tradable services, such as tourism and transportation. The strategy of having multinationals educate their workforce paid great dividends for the country. In the 1970s, Singapore was primarily exporting textiles, garments, and basic electronics. By the 1990s, they were engaging in wafer fabrication, logistics, biotech research, pharmaceuticals, integrated circuit design, and aerospace engineering. A Modern Economy Today, Singapore is a modern, industrialized society and entrepà ´t trade continues to play a central role in its economy. The Port of Singapore is now the worlds busiest transshipment port, surpassing Hong Kong and Rotterdam. In terms of total cargo tonnage handled, it has become the worlds second busiest, behind only the Port of Shanghai. Singapores tourism industry is also thriving, attracting over 10 million visitors annually. The city-state now has a zoo, a night safari, and a nature reserve. The country recently opened two of the worlds most expensive integrated casino resorts in the Marina Bay Sands and the Resorts World Sentosa. The countrys medical tourism and culinary tourism industries have also become quite successful, thanks to Singapores cultural heritage and advanced medical technology. Banking has grown significantly in recent years and many assets formerly held in Switzerland have been moved to Singapore due to new taxes imposed by the Swiss. The biotech industry is burgeoning, with drug makers such as GlaxoSmithKline, Pfizer, and Merck Co. all establishing plants here, and oil refining continues to play a huge role in the economy. Despite its small size, Singapore is now the 15th largest trading partner of the United States. The country has established strong trade agreements with several countries in South America, Europe, and Asia as well. There are currently over 3,000 multinational corporations operating in the country, accounting for more than two-thirds of its manufacturing output and direct export sales. With a total land area of just 433 square miles and a small labor force of 3 million people, Singapore is able to produce a GDP that exceeds $300 billion dollars annually, higher than three-quarters of the world. Life expectancy is 83.75 years, the third highest in the world. Singapore is considered to be one of the best places to live on Earth if you dont mind the strict rules. Singapores model of sacrificing freedom for business is highly controversial and heavily debated. Regardless of philosophy, though, its effectiveness is undeniable.

The musculoskeletal System - A Case Study - Short Answers Essay

The musculoskeletal System - A Case Study - Short Answers - Essay Example The wounds can be open or closed. Open wounds are common because the shaft of the tibia is just below the skin and subcutaneous tissue and is not covered with much soft tissue. Most of the tibial shaft fractures are associated with fibular fractures too. In Julia, the fracture occurred due to high speed accident. The fibula was however not involved and the wound was closed. The main sources of pain in Julia are the site of fracture, skin and subcutaneous tissue and the muscles surrounding the tibia. Fracture induces significant amount of inflammation and release of inflammatory mediators with cause pain, swelling, warmth and redness. During fracture, hematoma may be formed which can also cause pain (Rosenberg, 2007). Inflammatory cells, phagocytes and fibroblasts have a major role in the healing process of the fracture. Fracture causes formation of hematoma and a blood clot gets formed between the broken fragments of the fracture. After the initial few days following fracture, blood vessels grow within the clot. These blood vessels allow accumulation of phagocytes to the area which help in the removal of dead tissue. The blood vessels also cause pouring in of fibroblasts which multiply in the walls of the blood vessels and produce collagen fibres. These fibres replace the blood clot. The fibroblasts also lay down bone matrix or calcium hydroxyapatite which helps in the transformation of collagen to bone (Rosenberg, 2007). Factors which promote wound healing in Julia are immobilization, good nutrition, young age and absence of infection (Rosenberg, 2007; Konowalchuk, 2005 and Norvell, 2009). Immobilization is very essential to promote fracture healing. This is because, any movement of the fragments of the fracture hinder the process of healing. Movement disturbs the formation of clot and invasion of blood vessels within the clot. Decrease in the formation of blood vessels prevents invasion of fibroblasts essential for deposition of collagen and bone

Communication and Society Essay Example | Topics and Well Written Essays - 2000 words

Communication and Society - Essay Example Crucial to these claims is the position that communication could refer to the most common and the most mundane. This is Carey's way of using the cultural approach to defining and explaining what communication is. This is the case in the sense that human daily activities collectively constitute the meanings and the reality that we perceive. The Mobile Texting Phenomenon To demonstrate Carey’s position, there is the case of the use of short messaging system (SMS) in mobile phones. If one examines how people communicate through this platform closely, one will find a uniquely different lexicon employed. "How are you?" becomes "hw r u?" or "You are late." becomes "u r l8". Words are radically shortened by redacting words or substituting figures to represent sounds in order to accommodate the restrictions posed by the messaging service. Cell phones usually allow only 160 characters per message. According to Lindholm, Keinonen and Kiljander (2003), â€Å"in advanced phone markets, a s in Scandinavia, Germany, or the Philippines, a whole new culture has been born around text messages as a response to the limitations 160 characters impose.† (p115) This is in addition to other variables like the way the messaging application and interface are designed and the way people interact with it. An excellent example to demonstrate the above points is the use of the so-called "emoticons", symbols that convey emotions. For instance, there is the case of the smiley, :-) an emoticon used to express how pleased one is, or an agreement or a greeting depending on the context of the conversation. The resulting communication process and symbols start to create a reality for people that eventually form collectivities that emerge as social, cultural, and even political forces and even institutions. The severely shortened language, for one, has triggered an attitude among people today to prefer simple, fast and mobile way of doing things. Blogs or online journals became popular way back but it never achieved the degree of wide usage that Twitter has achieved today. Dubbed as a micro blogging platform, Twitter lets users use its service to publish details about people's daily lives in short, concise and uncomplicated manner, not unlike the way people would "SMS" or "text" others. This is in contrast to the way users are required to publish elaborate and detailed messages in traditional blogs like Blogger or Wordpress. The implication of this development in the context of communication and the manner by which it could shape reality is the way it affects behaviors. People become increasingly impatient with details and this is reflected in the way they conduct their affairs and what they expect from their interactions with others. The significance of the SMS phenomenon can also be described from a critical point of view. For example, Patajo-Legasto (2010) argued that mobile phones stifle literacy and young people’s ability to communicate in the real wo rld in real time by â€Å"wrecking havoc on spelling and grammar, and its erosion, in tandem with mindless computer games and Internet chat rooms.† (p410) Several other problems and criticisms were outlined. For instance, Clark and Brody stated: Part of the anxiety surrounding texting arises from its perceived tendency to disrupt protocols of recognition and
