Biochem unit 9 paper - Essay Example Vitamin E works with other molecules such as glutathione, selenium, vitamin C, and vitamin B3 in preventing oxygen from becoming too reactive, thereby preventing oxidative stress (WHFoods: vitamin E, n.d.). Numerous studies indicate that oxidation is the crucial phase in atherogenesis. Oxidized low-density lipoproteins with low density promote the production of inflammatory indicators. They are also implicated in the formation of foam cells, inhibition of vasodilation due to nitric oxide, and inhibition of the motility of tissue macrophages (Saremi & Arora, 2010). Experiments carried out on mouse models reveal that vitamin E plays a significant role in augmenting oxidative resistance in vitro, consequently avoiding the formation of atherosclerotic plaque. In humans, there is reduced risk of coronary heart diseases due to consumption of vitamin E-rich foods especially in middle-aged and older men and women (Saremi & Arora, 2010). However, results from some clinical trials provide conflicting data. According to Blumberg, vitamin E has been implicated as having an unfavourable effect in the therapy of heart disease (n.d.). He further attributes these disparities to the different primary and secondary tests. Primary prevention entails observing large numbers of healthy people and investigating the incidence of new heart disease in the midst of people with diverse intakes of vitamin E. On the contrary, secondary prevention takes place â€Å"over a few years in clinical trials with vitamin E supplements (and placebos) in patients with heart disease to determine whether their conditions worsen, e.g., with a subsequent heart attack† (Blumberg, n.d.). Therefore, vitamin E is more effective in primary prevention by preventing the development of plaque, which usually starts in childhood and continues in adulthood. Nonetheless, a number of studies indicate that vitamin E could

Power Crisis in Tamilnadu and Remedial Measure Essay Example for Free

Power Crisis in Tamilnadu and Remedial Measure Essay The Power Crisis in Tamil Nadu The power crisis has come to stay in the state of Tamil Nadu. For many months now, power cuts for over six hours in the towns and villages of the state have been the norm. Chennai, which till recently was spared the rigours of power shedding has now been brought into the ambit. This poses a question on the state trying to attract more and more investment, giving assurances of uninterrupted power supply. Load shedding which was originally meant for an hour or so, has now been extended to three hours in many suburbs of the city. While this has affected homes and ommercial establishments, the industries in and around the city (High Tension power consumers) have been hit hard by strict regulations on hours of load shedding, with many units being forced to shut down operations for an entire day each week. Industry sources are also upset over the fact that while manufacturing units consume only 35% of the 9500 MW power consumption in Tamil Nadu, they are being forced to suffer load shedding far more than domestic consumers. Many units have begun operating shifts with the help of diesel generators, but this is proving to be an expensive solution which is affecting the bottom line. There is also a growing feeling among indigenous industries that the state bit off far more than it could chew when it came to inviting large projects to set up base in and around Chennai. The increase in power consumption was not thought through in their opinion and there is also a feeling that multinationals are being given power at the expense of domestic companies. While there may be no basis for such a view, it does indicate that the state government has laid the ground for a potentially explosive situation on the power front. Perhaps it was against this background that the state only made a few eeble noises about bidding for the Nano project which eventually went to Gujarat. There is no short term solution to the power crisis in the city and the state. Interestingly, on paper, the state can still claim to have surplus power for it has around 10500 MW installed capacity. However real time production is less. Poor rains have affected hydro- power and the shortage of fuel has meant that the atomic power plant at Kalpakkam is operating at sub-optimum capacity. Relief to some extent is expected when the Koodamkulam plant is commissioned in about six months from now. Most of the newly approved power units are only in the land dentification stage right now. The losses in transmission and distribution of power are also significant with the state-controlled Electricity Board not performing at expected levels. Industry lobbies have been demanding the unbundling of production, distribution and transmission of power in the state to improve this, but there has been no response. The state government has on the other hand approached HT consumers with a proposal that they share the cost of power during evening hours. This if accepted will ensure that there is some relief given to units that rely on generators for their power during evening and other peak equirements. If at all there is a bright side to the story, it is the increasing focus on non- conventional sources of energy. IT majors who account for at least 500MW of power consumption during peak-hours nave begun discussing the viability ot using solar panels. At least one IT major in the city has begun working with wind energy. The month of September in fact saw the shortfall in power in the state coming down due to a doubling of the wind power generated from 600 MW to 1200 MW. It is to be hoped that such new thrusts will help in pulling the power sector out of its present mess.

Henri Cartier-Bresson Photography Analysis

Henri Cartier-Bresson Photography Analysis Critical commentary on the picture- Henri Cartier-Bresson: Michel Gabriel, Rue Mouffetard, 1952 The photo that I am going to analyse is taken by the famous French photographer, Henri Cartier-Bresson, in 1952. He was famous for his candid photography, which was later developed as another kind of art ‘Street photography. His contribution towards photography art finally helped him own the name of ‘the father of modern photojournalism. The photo mainly captures a boy, Michel Gabriel, who is holding two magnums with his arms, and his face is actually exuding a kind of happiness and confidence which could supposedly be seen on a mature mans face. There are also two little girls captured in the photo, but their presence is a bit blurred since the boy holding the wine bottles is the main character. As mentioned in the previous paragraph, the boy was portrayed as a ‘man who was proud to be a drinker. In fact, the relationship between the boy, Michel Gabriel, and the photographer, Henri Cartier-Bresson, was very subtle because actually the boy and the photographer did not know each other; the photographer just shot the boy in a candid way. Therefore, it can be said that the relationship between them is very subtle, which is the photographer vs. the model, or the man with a camera vs. a boy with wine bottles. In this photo, the theory, Affective fallacy, suggested by W.K. Wimsatt and Monroe Beardsley can be applied. Affective fallacy is supposedly defined as a confusion between the poem and its results, but later this theory is also generally used to apply to viewing photographs, meaning that readers interpret the photographs through his/her personal emotion or affectionateness. The boy is holding two wine bottles with satisfied facial expression; readers like me may view this photo on the basis of intuition that the boy is happy because he could drink alcohol like an adult. However, this interpretation may be wrong since we do not know the intention of the photographer. To be more objective, the boy may just run across something which was intriguing on the street, and the photographer just captured the moment. Another interpretation would be the boy is just carrying two wine bottles filled with water (or empty) around for fun, which can be inferred from the background of the photo. First, the apartment and street implies that the place where the boy walks is a working class distract. Therefore, wine is possibly not affordable for a child like him; he may just play what popular within the working class area at that time. Second, the ambience of black and white of the photo, the clothing style of the boy, the impressed girls behind him, and the date can also help convince the readers that the boy is playing at the moment. However, if readers refer to the statement of Cartier-Bresson, the interpretations will be different. As Henri Cartier-Bresson said ‘photography is a way of shouting, freeing oneself, not of proving and asserting ones originality, so photography is a mean of telling the story or truth in which it captures the conversation, facial expression, gestures and presents them in a visual way which can be for later reflections. The meanings that are being shouted or freed by the photographer would be the concern about the boy drinking alcohol, about the drinking habits of his parents, and even about the way that the boy lives under the influence of his parents. The statement of Cartier-Bresson is thus in line with the viewpoint of Benjamin stressing that ‘photograph can release meaning that was not perceived at the time. There is no doubt that photography can capture an object; it can also capture time in which the moment will last forever. Therefore, the viewpoint from Kracauer is true because he stress that ‘photography captures time- memory outlast time, meaning that the image together with the meaning would become memory which can be recalled. Taking this photo as an example, it does document the time when people were living in Rue Mouffetard, and also the aura of surrounding area. Therefore, it is a good documentation recording the community life during that period. Yet, reading an image sometimes goes problematic as the photographer (creator) does not always provide a lucid explanation or his/her interpretation for the photos; therefore, different interpretation can be resulted. Using this photo as an example again, whatever the photographer, the boy, his parents, or even the girls behind the boy, they may have their own interpretations towards this photo. That is why sometimes reading images goes problematic. But I have to say that this ‘problematic reading can, to a certain extent, stimulate the imagination of readers, from the surface to the underneath of photos. With no doubt, the prevalence of ‘street photographs or ‘candid photographs can be attributable to Cartier-Bressons contributions. However, nowadays, this kind of art seems to be abused because you can see a lot of candid photographs through different social networking websites, blogs, etc. However, it has somehow become a flood because most of the photos taken, especially in my hometown Hong Kong, have no meanings; the photographers themselves even do not know what meanings they want to express or deliver to the readers, thus, it is a bit sad because what the readera can access may be just the superficial meanings. The reader, as well, should also view a photograph in a deeper way in which he or she can access to different dimensions of the photographs. Nowadays, people are inclined to glimpse photographs instead of reading them. He or she may only get the very superficial meanings of the photographs. That is why sometimes we need to view a photograph with theories. For me, the photographic theories do help me to view a photograph in a deeper and more complex way. I am impressed by what Cartier-Bresson said ‘taking photographs is a means of understanding which cannot be separated from other means of visual expression; it is true because once you press the shutter of your camera, the relationship between the object and you has been set up. However, you cannot deeply understand the object by just glimpsing it. A good photographer captures time; a good reader captures the meanings behind. Benjamins theory on photograph said ‘photograph can confirm ideological thinking, I absolutely agree to the statement as I think a photograph itself can establish discourse and semantics in its own world; that is why a photo can decode the culture, values whatever of an object or of a particular place. Therefore, I think that reading a photograph is quite similar to reading a text in which readers need to undergo the process of decoding. In a text, readers have to decode the words into image while in a photograph, they have to decipher the hidden meanings (images) into words. It can be said that readers can fully understand the photographs unless they immerse themselves in the hidden dimensions of the photographs. If a reader only views the photo through a glimpse, what he/she can get is superficial. Reference: http://www.biographybase.com/biography/Cartier_Bresson_Henri.html

Recruitment and Retention in Speech -- Language

Addressing the Significant Shortage in the Profession Speech-language pathologists (SLPs) are in high demand throughout the United States. The U.S. Department of Labor’s Bureau of Labor Statistics (BLS) projects that the United States will need â€Å"about 141, 400 SLPs through the year 2018 to meet the increasing need in the profession and to replace retiring SLPs† (2011, p. 2). The demand for qualified professional in the field continues to rise from year to year. According to the BLS Occupational Outlook Handbook, 2011-2012 Edition, â€Å"employment is expected to grow 19% in the profession in the next decade† (p. 2). A report released in 2008 by the American Association for Employment in Education (AAEE) reported â€Å"SLPs are ranked 14th in the nation for fields with a considerable vacancy as related to other areas in education† (p. 8). In the state of Nebraska, the U.S. Department of Education listed speech language pathology as a â€Å"significant teacher shortage area† (2011, p. 58). Recruiting and retaining qualified professionals has impacted school districts across the nation. The frustrations of many SLPs are similar: job dissatisfaction, lack of sufficient compensation, and oversized workloads contribute to the professional shortage. Research suggests that â€Å"lack of recognition, few opportunities for promotion, excessive paperwork, loss of autonomy, lack of supplies, low pay, and stressful interpersonal interactions all contributed to teachers’ decisions to leave the schools† (Blood, Ridenour, Thomas, Qualls, & Hammer, 2002, p. 283).

Prelude to Philosophy: What is Philosophy? Essay

List 4 reasons students often presuppose a low view of philosophy. 1. The image that one has to be super intelligent to do philosophy. 2. As a discipline, most students study it late in their academic development. 3. Most people don’t think it’s practical. 4. Most students don’t know what philosophy is or how it can benefit them. Know Socrates’ quote: What is the unexamined life? What did he mean when he said it wasn’t worth living? The quote: â€Å"The unexamined life is not worth living.† Socrates didn’t mean that people have no value, or should be executed if they lived unexamined lives. Humans are unique in the animal kingdom; we have the ability to reason and reflect about everything. What he meant was: To live the unexamined life is to live less than a fully human life; not living life the way we were created to live. Know the etymology of the word â€Å"philosophy.† The combination of two Greek terms: phileo and sopos. Phileo means â€Å"love†, sophos means â€Å"wisdom†. Know the working definition of â€Å"philosophy† and explain each of its elements. Philosophy is the critical examination of our foundational beliefs concerning the nature of reality, knowledge, and truth, and our moral and social values. List and explain each of the 6 characteristics under the description of philosophy. 1. The relationship between philosophy and facts: philosophers are generally more interested in what lies behind the facts, their meaning, significance and veracity, than in the facts themselves. 2. The importance of method in philosophical investigation: why someone believes something more so than what they believe. 3. clarification: clear thinking is imperative in finding truth. Two enemies to clear thinking is ambiguity and vagueness. 4. Philosophy examines and evaluates everything; nothing is  taken for granted: Every belief and idea is open to critical examination. Clarification and justification are required before accepting any belief to be true. 5. Philosophy is usually concerned with foundational issues that have been perennial throughout the history of humankind. 6. Philosophy often appeals to systems of principles or guidelines regarded to be true: either reject new claim to be true or adjust system to adapt to the new claim. Philosophers build systems of beliefs and philosophical examination doesn’t begin from a neutral position. Contrast and compare philosophy with religion, science, and art. How are they different and how are they similar? 1. Philosophy and Religion: (compared) Both search for the ultimate – that which has the ultimate meaning and value, the one thing that unifies everything and from which everything finds it’s meaning and origin. (contrasted) Religion usually appeals to some authoritative revelation to discover the truths about the ultimate; philosophy uses rational inquiry in attempting to understand the ultimate. A spiritual aspect normally isn’t found in philosophy. 2. Philosophy and Science: (compared) Both try to understand reality in a methodical fashion. They both use observation and appeal to evidence to support their conclusions. They both derive criteria, hypotheses, and theories that they apply to specific situations to discover the truth about reality. (contrasted) Science generally examines that part of reality associated with the senses, the physical world, philosophies field extends outside of physical reality to what lies beyond. Also, science deals with first-order questions about reality, philosophy deals with second-order questions about disciplines like science. 3. Philosophy and Art: (compared) artists often use their medium to express philosophical ideas, they both also often deal with similar topics, and artists capture what some modern philosophers promote. (contrasted) Art usually only coveys a particular philosophical view, whereas philosophy seeks the rational justification of a view. Philosophy argues for a view, art expresses it. Art is concerned mostly with structure, philosophy is concerned mostly with content. Explain the value of experiential knowledge in distinction to propositional knowledge. Experiential knowledge enhances our understanding beyond what  propositional knowledge can convey. Philosophy: Examining life; love of wisdom. Unexamine Life: Going through daily/routine activities/life, without thinking about what you’re doing and why you’re doing it; going through the motions of life without making the effort to reflect and think about what life is about. Normative Claim: Makes a claim about some actions persons ought to do. Socrates’ â€Å"unexamined life† claim was a normative claim. Wisdom: Wisdom has less to do with how much one knows and more to do with how one uses the knowledge they have. Wisdom is knowledge applied; using the knowledge one has in a way that benefits life. Critical Examination: To analyze. Clarification: To determine what something means. Justification: Addresses the questions: Is this true, and are there good reasons to believe it’s true? Evaluation: Determines the significance or value of the idea. Presuppositions: Beliefs people usually don’t think about or try to prove. They are assumptions people hold about themselves and the world, without knowing which they would not be able to arrive at any other knowledge. Foundational Beliefs: Central and fundamental beliefs, the core of all other beliefs. First-Order Discipline: A field that directly studies reality. Second-Order Discipline: A field that studies the methods and presuppositions of first-order disciplines. It’s not interested in the conclusion but the  means used to arrive at the conclusion and the presuppositions held while attempting to answer the question. Ambiguous: When there is more than one possible meaning. Vague: When the meaning is not clear. Worldview: A comprehensive system of beliefs that functions, first as an explanation and interpretation of the world and, second as an application of that system to the way people live and the values they hold. Scientism: The notion that scientific knowledge is the only kind of knowledge there is. Propositional Knowledge: Consists of beliefs that can be formulated and conveyed in propositions. Experiential Knowledge: Knowledge gained through experiencing something. Rational Animal: Humans.

Contemporary Approaches Essay

Kaplan University There are four contemporary approaches discussed here in our Unit 2 reading sociotechnical systems theory, quantitative management, organizational behavior, and systems theory. They are to help an individual are group organization. All of these approaches should be taken into consideration when striving to compete in competitive business environment. I think organization behavior is the most important because the approach is the ystematic study of knowledge about how people – as individuals and as groups – act within organizations. The dynamics of group behavior and of the formation and suitability of any group need to be understood and implemented well, in order to achieve a harmonious working environment. Organization behavior is a contemporary approach that also studies and identifies management activities that promote employee effectiveness by examining the complex and dynamic nature of individual, group and organization processes. Sociotechnical system theory is different from organization behavior because, sociotechnical system is a theory to help design Jobs that attempts to redesign tasks to optimize operation of a new technology while preserving employee’s interpersonal relationships and other human aspects at work. It’s effective when their employees have the right tools training and knowledge to make products and services that one valued by customers. Quantitative management shows it’s different in helping anager make decision by developing formal mathematical models of the problem. Instead it finds the best solution to problems. In which then can be applied to different workplace challenges. What make systems theory different is, Systems theory addressed the role of the external environment. A system is a set of interdependent parts or elements which function as a whole in achieving certain goals or objectives.. REFERENCE www. ncefbsc. com/contemporary approaches. html
