Of White Hairs and Cricket

â€Å"A Horse and Two Goats† is a short story written by R. K. Narayan, from India. Basically, the story is about two individuals, an American and an Indian, trying to converse and communicate, but they can not seem to understand each other because of the lack of knowledge in the other’s language and culture. The story spans a very short time, perhaps a half an hour. As it is revealed in the very beginning of the story, it takes place in a very small village called Kiritam, which is only represented by a tiny dot on the local survey map. The narration of the story goes chronologically, in a third-person omniscient view, with the main characters being an American tourist and an old Indian man. Both of the characters seem a little bit ignorant and ethnocentric, as none of them have competent background knowledge of the other’s culture and language. The fact that they can not understand each other can be looked upon as the main conflict. However, by what is told, it seems like if the American should know more about Indian culture, than what the old man should know about the western ways. This is because the American is a wealthy person, probably a businessman, from New York, who has had a lifelong dream of visiting and seeing India. Somebody like this should probably had more cultural knowledge that what is shown. Along with this, he shows lack of respect when he sees a statue he finds to his liking, and wants it in his possession at once. He thinks he can just purchase it from the old man, without considering what the statue means for him or the native people. This way, the American is presented as a typical wealthy western person, who is quite materialistic and thinks that money solves all problems. What can be considered as odd, and perhaps just another example of western ignorance, is that the American naturally assumes that because the old man stands beside the statute, he owns it.

Enzymes: Lab Report

Introductory Biology 1 Biology 1003 Fall Term 2011 Lab Number: 3 Title: Cell Energetics: Enzyme Role in Biological Reactions Name: Brandon Moore Student Number: 100819124 Lab day and time: Wednesday pm Date: Wednesday November 23, 2011 Introduction Enzymes are a key aspect in our everyday life and are a key to sustaining life. They are biological catalysts that help speed up the rate of reactions. They do this by lowering the activation energy of chemical reactions (Biology Department, 2011). In chemical reactions bonds must be broken and new bonds must be formed. In order for this to occur the bonds must be made less stable. For bonds to become less stable a small input of energy is required and this is called the activation energy. In simpler terms, in order for a reaction to begin and proceed spontaneously a small input energy is required to give the reaction a push and get it started (Cooper, 2000). As said before catalysts are chemical agents used to speed up the rates of reactions. The biological catalyst is a group of proteins called enzymes. Enzymes work by lowering the activation energy and making it easier for the eactants to obtain the necessary energy to break the kinetic barrier. Even though enzymes speed up the rate of reaction, they do not change the free energy of the reactants and the products (Russel et al. , 2010). Enzymes work by combining with reacting molecules at the active site. Each enzyme is specific to only one kind of molecule and can only bind to its specific molecule. The active site is a groove in the enzyme wher e the molecule will bind to; this is formed by the enzyme folding into a specific shape. When the enzyme is done and the molecules are then in the transitional state, which means the bonds are unstable and ready to be broken, the enzyme remains unchanged and can continue to bind to other molecules (Russel et al. , 2010). Enzymes induce the transition state by three major mechanisms. The first is by bringing the reacting molecules together. The reactants bind in the active site of the enzyme in the right orientation for catalysis to occur. The second mechanism works by the enzyme exposing the reactant molecule to altered charge environments. The third mechanism is by changing the shape of a substrate molecule (Russel et al. , 2010). The conditions being studied on how they affect enzyme activity are: concentration, ph, and temperature. As the concentration of enzymes increases the rate at which products are formed also increases. It is also true as the concentration of the substrate increases the rate of the reaction will also increase until the enzymes reach their maximum rate at which they can combine with the substrates. Each enzyme has a best possible pH where it works at its best. Anything that changes on either side of the optimum pH will decrease the rate of the reaction. Finally as temperature raises so does the rate of the reaction but only to a certain point. As the temperature raises the frequency and strength of collisions will increase, however if the temperature rises too high the hydrogen bonds of the enzyme break and it unfolds making it unable to accept any molecules due to its active site being destroyed. To observe the effects of these three conditions on enzyme activity spectrophotometry is used. A spectrophotometer works by measuring the amount of light a compound in solution absorbs. As the concentration of the solution increases more light is absorbed (Biology Department, 2011). The purpose of this experiment is to test and observe the effects of concentration, pH, and temperature on enzyme activity. Methods In part I of the lab obtain six small glass tubes in a test tube rack. After the six small tubes are obtained, add fifteen drops of distilled water to tube 1, ten drops to tube 2 and 3, five drops to tube 4, and no drops to tubes 5 and 6. Once distilled water is added five drops of the substrate solution were then added to tube 2, 4 and 6. There were no drops of substrate solution added to tubes 1 and 3, and ten drops were added to tube 6. After the substrate solution was added, five drops of the enzyme were quickly placed in tubes 3, 4 and 5. There were no drops of enzyme added in tubes 1 and 2 and in tube 6 ten drops were added. Once the enzyme solution has been added the tubes were then left to incubate for ten minutes and after five drops of DNSA solution were added to tubes 1 to 6. The tubes were then placed in a hot block at 80-90oC for five minutes. They were then taken out after the five minute period and using a 5 ml pipette, 5 ml of distilled water were added to the 6 tubes and mixed by inversion. Once everything was complete the 6 tubes were then taken to the Milton Roy Company Spectronic 21 and the absorbance of each tube was tested. In part II of the lab six small glass tubes were obtained in a test tube rack. Ten drops of distilled water were then added to test tube 1, five drops to tubes 2-4, and no drops in tubes 5 and 6. Five drops of 0. 1M HCl were added to test tube 5 and five drops of 0. 1M NaOH to test tube 6. Five drops of enzyme were then added to all tubes except tube 1. Tube 3 was then placed in the ice bucket and tube 4 was placed in the hot bucket at 80-900C for five minutes, the remaining tubes were left in the test tube rack. After the five minutes five drops of 1% starch was added to every tube and left to sit for ten minutes. After ten minutes five drops of DNSA were then added to all the tubes. All the tubes were then taken and placed in the hot bucket at 80-900C and left to incubate for five minutes. After the five minutes, take a 5 ml pipette and add 3 ml of distilled water to each tube and mix with inversion. Once everything is complete the tubes were then taken to the Milton Roy Company Spectronic 21 and the absorbance of each tube was tested. Results In part I tubes 1-3 had a very low absorbance. In tube 4 when the enzyme and substrate were present the absorbance increased substantially from below 0. 1 to a mean of 0. 53. When two times the amount of substrate was added in tube 5 the absorbance increased again from a mean of 0. 53 to 0. 57. Finally when two times the amount of enzymes was added the absorbance increased a final time from 0. 57 to 0. 63. Table 1.

Increases in concentration increase the rate of the reaction, change in pH from the optimum will decrease the rate of a reaction, and increasing temperature will also increase the rate of reaction until a certain point is reached (Worthington Biochemical Corporation. 1972). Part I of the lab focused on the effects of concentration on pH. When we look at table I we can see that tubes 1-3 had very low absorbances. Tube 1 was the control that contained only water and no reaction occurred. In tube 2 the enzyme was not present which meant that the reaction occurred spontaneously without any help, thus a low absorbance. Tube 3 contained the enzyme but lacked the substrate, which meant nothing was bonding to the active sites and reaction could not occur. In tube 4 both substrate and enzyme were present and the absorbance rose greatly from approximately 0 to a mean of around 0. 3. This perfectly demonstrates that with the addition of an enzyme the product concentration increases and so does the rate of reaction. To tube 5, two times the amount of substrate was added and absorbance increased again to a mean of 0. 57. This shows that more substrate was present and readily available to bind to the active sites. Last was tube 6 which contained two times the amount of enzyme and again the absorbance rose to approximately 0. 63. The increase of enzymes allowed for more active sites to be readily available to bind to the molecules (Worthington Biochemical Corporation. 1972). When viewing the data obtained and comparing it to what is known about concentration effects on enzyme activity it can be accurately concluded that the data obtained is fairly accurate. As the enzyme concentration is kept the same and the substrate concentration increases the rate of reaction will also increase. This makes sense since now there are more molecules of substrate available to bond to the active sites. Increasing concentration will only increase the rate of reaction until a certain point is met. This point occurs when too much substrate is added and all available enzymes are already working. When this occurs the concentration increase no longer has an effect on the reaction rate. This is also true with the increase in concentration of the enzyme. The more enzymes there are the more active sites available to bond to the molecules. The increase in enzyme concentration will also increase the rate of reaction. This concludes effectively that the data obtained effectively demonstrates the effects of concentration on the rates of reactions (Worthington Biochemical Corporation. 1972). Part II of the lab focused on the effects of temperature and pH on enzyme activity. When viewing table II it can be seen that tube 1 had a very low absorbance, due to it being the control and not containing any substrate or enzyme. Tube 2 contained the substrate and enzyme and thus the absorbance increased greatly to a mean of 0. 54. When looking at the changes of pH in tubes 5 and 6 the absorbance decreased for both to 0. 003 and 0. 1. The optimum pH is around 7 and with this the reaction rate is at its best. As stated before any change in pH away from the optimum will decrease the rate of reaction. HCl has a lower pH than 7 and is below optimum, which means that it will have more unstable charges and the absorbance will lower, which is what was seen in tube 5. The same happens for NaOH, which is on the other side of the pH spectrum and above the optimum pH of 7 as seen in tube 6. From this it can be concluded that any change in pH away from the optimum will cause an unbalance in charges and cause the reaction rate to decrease (Worthington Biochemical Corporation. 1972). The second part of part II involves the effects of temperature. When looking at tube 3 that was placed in the ice bucket the reaction rate decreased from tube 2 with mean absorbance of 0. 54 to a mean of 0. 32. A decrease in temperature will slow down the activity of the substrate and enzymes and will reduce the speed and amount of collisions occurring. With less collisions occurring the reaction rate will then decrease. Tube 4 was placed in heat and the absorbance dropped as well to a mean of 0. 38. Stated before it was said that an increase in temperature would cause the speed and number of collisions to increase. This would then increase the rate of the reaction. However, an increase in heat will only increase the rate of reaction until a certain temperature is reached. This temperature is approximately between 40-50OC. Tube 4 was placed in temperatures ranging from 80-90OC, which is much higher than the max of 40-50. When this max is surpassed the hydrogen bonds will begin to break and the enzymes will unfold. When the enzyme unfolds the active site will then be destroyed and become deformed and no longer usable. When this happens the enzymes stop functioning and the reaction rate will decrease, which is what was seen (Worthington Biochemical Corporation. 972). The living cell is a site for activity known as metabolism. This can include the build-up or repair of tissues, turning food into energy, getting rid of waste products, and all the activities of life. Many of these processes do not occur spontaneously and this is why enzymes are needed. Without enzymes life itself would not be possible (Cooper. 2000). It can be concluded that concentr ation, pH, and temperature have great effects on enzyme activity. The increase in concentration of substrates increases the reaction rate until the point where all enzymes are being used. The increases in enzyme concentration will increase the rate of reaction. Any change in pH away from the optimum will cause an unbalance in charges and will lower the reaction rate (Worthington Biochemical Corporation. 1972). Finally the increase in temperature will increase the reaction rate until around 40-50OC when hydrogen bonds begin to break (Russel et al,. 2010). By understanding more about enzyme catalysts advances in medicine and life sciences are able to occur and help us understand more about life itself. References: Russell, P. J. , S. L. Wolfe, P. E.

Caro Goar’s Perspective on Senior Citizens Take on Carewatch and Ageism as Written in Goar

Caro Goar’s Perspective on Senior Citizens Take on Carewatch and Ageism as Written in Goar According to the article â€Å"Senior Citizens are Mobilizing Against Ageism: Goar,† written by Carol Goar of the Toronto Star, people in the Canadian community are striving to make a difference towards ageism. Carewatch is a social action committee. They have discovered that ageism is present in many shapes in forms. They noted that ageism is seen in many places: in government, business, fashion, the media, social services, and advertising. The author noted that there was a three step process that the city is using in order to fight ageism. The first step is to take back the title â€Å"senior citizens†. Older citizens in Canada do not appreciate the fact that they aren’t being recognized as senior citizens. Most people refer to these older adults as seniors only. Many senior citizens feel like society should not shorten the phrase to only one word, and that it is important to include both words. The second goal was to provide senior citizens adequate home care through designed funding. The third goal is to get other organizations involved to help solve the problem of ageism in Toronto, Canada. Carewatch is a fifteen year nonprofit that consists of â€Å"a voluntary group of active, informed senior citizens†. Their goal is to be able to be more involved in society. Through this nonprofit, the group hopes that senior citizens have the opportunity to have more control, respect, and human rights. Based on the article, it is said that ageism is the only form of discrimination that is still generally accepted in Canada. Carewatch hopes to put an end to this, where senior citizens can live self-sufficiently with the right support services. One problem that they addressed is that senior citizens tend to keep their age a secret. Whether it is their appearance, form of speech, or the way they act, senior citizens try not to reveal their age. Part of the problem was recognized by Neysmith. Ageism is present in government, business, fashion, the media, social services, and advertising. For example, not one senior citizen was placed in a brochure advertisement for the Pan Am Ga mes Secretariat. Neysmith is hoping to â€Å"convince other organizations that the best way to get actions was to band together.† Ageism is known as the discrimination and stereotyping of older adults. This concept is present in Toronto, Canada, as well as the rest of the world. Ageism can really affect the elderly in a negative manner. This has the power to instill a fearing about getting older. This could lead to dependency, segregation, and the mistreatment of the elderly. It is unfortunate how ageism really separates â€Å"younger people† from â€Å"older people†. This type of inequality is unfair because the elderly are given less power. The way print media and electronic media portray older adults is unfair. In this case, older adults were not included in a brochure advertisement. Ageism is demonstrated in many ways. Ageism is present in the workplace. For example, they are not given many opportunities compared to workers who are younger than them. This includes not receiving any training, compensation, or promotions. I only hope that Carewatch’s efforts follow through. I would have to agree with their efforts. I believe that one way to help push this idea forward is by working with other organizations. By doing this, this will spread more awareness about the unfair treatment of the elderly. This can eventually lead to some sort of response, with a step towards giving the elderly what they truly deserve – human rights, respect, and home care. What I didn’t realize was the fact that the eldery try to hide their age. That was a statement that really surprised me. I didn’t take notice of that until I started reading this article. Although this may happen, society should be supportive of senior citizens regardless. We shouldn’t perpetuate these negative perceived ideas with the elderly. The creation of this nonprofit may not seem important to many, but I feel like it is a great idea. I hope that this type of discrimination gets put to rest in the near future.

The development of teaching physics through modeling as pedagogical Essay

The development of teaching physics through modeling as pedagogical method in the United States - Essay Example In 1821, when the first public high school in America opened, physics was already a part of the curriculum. By1886, Harvard College established a physics laboratory to improve the physics teaching establishment (Hurd, 1969). We may wonder how physics was taught back then. What caused the development of modeling? The purpose of this literature review is to understand the modeling method that is being applied in physics classrooms today, how this method developed and how physics teachers are being trained to have more effective teaching methods into the future. In scientific terms, a model is a representation of a phenomenon initially produced for a specific purpose. As a ‘phenomenon’ is any intellectually interesting way of segregating a part of the world-as-experienced for further study, models are omnipresent. Teaching science as inquiry is among the most important science standards to be passed to future generations. Modeling is part of teaching science as inquiry beca use it enhances students’ critical thinking skills. For this reason, teachers, such as physics teachers, who play a big role in applying inquiry in the science classroom must be knowledgeable in modeling techniques to encourage students to think critically in areas of inquiry. Modeling constitutes a complete open learning environment appropriate for students 11-17 years old. It supports students as well as teachers during learning/teaching activities.

What is ethis Can ethics be taught Term Paper Example | Topics and Well Written Essays - 500 words

What is ethis Can ethics be taught - Term Paper Example For example, in some fundamental societies, killing of people who say something against the religion is accepted as a sacred act. According to newspaper reports, Indian capital New Delhi faced a severe terrorist attack in which more than 10 innocent people were killed. The terrorist who accepted responsibility for this attack was a fundamental Islamic terrorist organization. For them, what they did in Delhi is ethical. But for others, it cannot be considered as ethical. So it is not necessary that religions or the society may always teach moral activities. From the above discussion, it is clear that ethics cannot be taught; but it should be learned through logical analysis and synthesis of experiences in the past. â€Å"When most people think of ethics (or morals), they think of rules for distinguishing between right and wrong† (Resnik, 2010). My personal code of ethics is formulated in line with the above argument. In fact my personal ethics has nothing to do with my religious beliefs. I have no hesitation in accepting the good teachings of other religions. For example, according to Christian and Muslim belief, killing of animals for food is not a sin. However, Buddhism and Hinduism consider all types of killing as sin. I have no hesitation in accepting the arguments of Buddhism and Hinduism as far as killing of animals is concerned. For me, any activity which may not cause any kind of discomfort to others can be considered as ethical. When I was working in the production department of an organization, a sales executive who is working for another company approached me with a major job. Even though his organization has all the facilities to complete that job, he told me that he doesn’t want to complete that job with the help of his own organization. His intention was to make more money out of this job. Since my organization has lack of works at that time, his offer put me in a dilemma. According to my

What do UEL Students think about the Future of University Education Assignment

What do UEL Students think about the Future of University Education and Why - Assignment Example Because of the many concepts identified through research the study could not develop a workable hypothesis based on initial findings, the study took an inductive approach whereby the literature review was used to model questions for use in the primary study (Price 2011). The aim of the study based on the findings in the initial review of literature was to develop new models or explanations and understandings about the future of education through the lens of university students; an exploratory research approach. Initial research studies identified many different arguments about the future of education, including structural changes to the classroom, distance learning through e-systems, increasing tuition costs and even more interactive tools and instruments based on changing curriculum in-line with business evolution. The most common theme identified was the presence of e-learning as a foundation for the future of university education. Because of the enormous volume of literature on th e subject, e-learning became the focus of this primary study. Literature review E-learning is the use of various electronic applications and systems to promote educational learning. These include â€Å"web-based learning, computer-based learning, virtual classroom development and digital collaborations† all delivered through Internet, satellite television, CD-ROM and intranet systems. (Manochehr 2004: 10). According to a recent report published by the Sloan Foundation, e-learning systems have achieved a 12-14 percent growth rate since 2006 (Mihai, Sanciu and Aleca 2011). In the United States alone, as one example, there are currently 3.5 million students using online education systems within higher education environments (Mihai, et al.). It is forecasted that e-learning will, by 2014, be in 81 percent of global universities (Mihai, et al.). Another recent study with a sample population of 289 respondents, 189 of which were from higher education environments and 100 from corpo rations, identified current usage of electronic learning. In the study, 44 percent of respondents used blogs to teach, 53 percent video podcasts, 71 percent online courses, 56 percent social networks, 66 percent text messaging and 49 percent mobile broadband (The Economist 2008). What significantly supports the notion that e-learning could represent the future of university education is that this study consisted of respondents from Europe, The United States, Asia and other international countries (The Economist). There is significant growth in usership of e-learning systems both in universities and the business environment. According to Clark (1999) students who use distance learning via the Internet have similar performance levels to that of students taught in the physical university environment. The researcher conducted a study of student performances from 1928 to 1999 after cataloguing 355 different research reports during this 69 year period and discovered equal achievement with both types of learning (Clark). High achievement in distance learning via the Internet continues to make this teaching system an incentive for universities around the globe. Further, there is also significant growth rate in the use of social networking and video sharing sites on the Internet. According to the Copyright Clearance Center (2009), there were 12.7 billion Internet users that viewed videos in 2008, an increase of 34 percent from 2007. Video sites allow the instructor to post their lectures online at a low cost, thus providing education for users not only in Europe but around the globe. Sanborn, Santos,

Global Operations Management of Wal-Mart Essay Example | Topics and Well Written Essays - 1250 words - 2

Global Operations Management of Wal-Mart - Essay Example The paper tells that global supply chain management focuses on the process of planning and optimizing the different international and local processes of procurement, production, and distribution. In order to manage the global or international supply chain in effective and efficient manner, it is required to integrate all supply chain partners in the overall process. Wal-Mart is operating in the industry of international retailing for a couple of years. The company has been in the business of providing different products and goods to the end consumers all over the world. Wal-Mart is known to be one of the largest retail organization in the global industry. Apart from different physical superstores and hypermarkets, Wal-Mart has also entered into the industry or electronic commerce by offering products through online retail stores. Wal-Mart has been able to create the competitive edge in the industry on the basis of considerably low prices. And for this, it has used efficient and effec tive supply chain strategies to increase the responsiveness of the global supply chain and at the same time increase the overall efficiency of the supply chain. Wal-Mart has been able to integrate different stages and partners of the supply chain together with the help of different technological systems like Enterprise Resource Planning (ERP) system. The supply chain of Wal-Mart is more complicated because of the fact that it has to integrate different manufacturers in the whole process. For example, the let's consider the example of a simple detergent provided by the company. Production is about producing and manufacturing different products and goods. In reference to Wal-Mart, the main function of production is handled by different manufacturers and Wal-Mart focuses on the process of making these products

The Vigilance Project Essay Example | Topics and Well Written Essays - 1000 words

The Vigilance Project - Essay Example Being in a group, an individual feels as integral part of a team which enhances his or her self-worth. 4. Realistic is conflict â€Å"based on scarce resources†; symbolic conflict is conflict â€Å"based on values and beliefs†. Realist conflicts take place between groups over scarce resources in a competitive environment. Symbolic conflicts occur due to different perspectives regarding values and ideas which give rise to conflicts in goal persuasion. 5. The leadership paradox is best stated as â€Å"The fact that teams usually need leaders, but the very presence of a leader threatens the autonomy of a team†. Instead of making a team more productive, a leader may end up being a hindrance if he overuses his power (Thomson, 2004, p.309). 6. The three types of team coaching include â€Å"ability, coordination, motivation†. Motivation enhances team commitment, coordination helps people to work together, and educational coaching increases skills and abilities of team members (Levi, 2010, p.178). 7. Teams that are underbounded â€Å"Have many external ties, but cannot bring its members together†; in contrast, teams that are overbounded â€Å"have high loyalty but an inability to integrate with others†. Overbounded teams are highly cohesive and so members can work in more coordinated manner than underbounded teams (Hackman, 2011, p.79). 11. According to the empirical research on convergent and divergent thinking, â€Å"Groups are better than individuals at divergent thinking; individuals are better than groups at convergent thinking†. This is because in the latter effort is to find single solution to a problem while in the former effort is to find multiple solutions to a problems which can be more effective in a group (Salkind, 2005, p.309). 12. The key threats to creativity do not include â€Å"social striving†. Social striving means individuals can exhibit maximum performance when working as part of a group, and this can enhance creativity (Shiraev & Levy,

Audience Analysis and Adaptation Assignment Example | Topics and Well Written Essays - 250 words

Audience Analysis and Adaptation - Assignment Example However, Mrs Bush shares her experience of coming to Wellesley 10 years back. She identifies with the students by describing how she was struck by the natural beauty of the campus and then tells a story about Wellesley students where she stresses on the spirit of the college. This way she relates with the students. She very wisely talks about human connections and their importance in our lives. She addresses the concerns of the audience by speaking about the success of a family and loving children. Mrs Bush says that she wishes the winner of the annual hoop race to realize her own dreams – not society’s dream – and not just be the first to get married or the first to become a CEO. By speaking in their interest and addressing the issues related to their lives, she defuses the hostility they held against her. If Mrs Bush would have been delivering the speech at some other higher education institute, she would have probably not have stressed too much about her personal life. She would have interacted more with the students so as to relate with them. Infact, she would have highlighted the achievements of the institute and spoken about how she would have loved to be a part of the institute. She would have spoken more about the issues related to nation and society so as to draw their

Democratic Education Essay Example for Free

Democratic Education Essay Democratic Education should be a mainstream style of teaching, and should be taught specifically to anyone aspiring to become any type of successful instructor. Everywhere you go the world is constantly changing, people adapt, time ticks away, and the days come and go, every waking moment is progression to the future. Why is the one thing that we as a society depend on for survival going backwards? Our education system and the way we educate children is the only tool we as a society use to ensure our existence, think of the world as a well oiled machine. If you neglect certain parts, yes maybe it will keep working for a short while. Eventually the machine will fall apart because of the mistreating and lack of or poor maintenance, if we keep neglecting our education system by turning a blind eye to the type of educators we give teaching credentials to or the way our current teachers or professors are instruction our future, then our existence is headed for an abrupt halt. Schools need to embrace interesting, interactive-learning environments throughout the curriculum. â€Å"If you do not want to do something, you will not, period.† This thought means if someone is in a place that does not at least entertain the senses, let alone stimulate the mind then why even waste the time to just be physically be present? By doing that it wastes money, and more importantly the teacher and the students time. Democratic education as a teaching style is based on â€Å"affirmative authority without disrespect of freedom†; Democratic Education, by bell hooks. Authoritative guidance with inspiring, limitless, encouragement should be the goal of every type of educational course offered in the United States. We need to input this style of teaching into our aspiring teachers required classes to graduate at any institution or university across the country. We need democratic education because this type of teaching inspires the students, just because someone passes a test or any kind of written exam does not determine someones intelligence. The definition of the term intelligence, according to www.google.com, means the ability to acquire and apply knowledge and skills. This applies to institutions and their instructors because if a pupil is not taught how to apply these skills he or she has been taught how does this apply to the fast-pace times that we live in today? The answer is, it does not. Democratic education benefits the entire classroom rather than just a select few because of the more upbeat style of teaching. The beauty of democratic education is that it can also be incorporated with the old style of a more text-geared curriculum as well. It has the potential to improve teaching as a profession because it would lengthen the required courses to become a teacher, therefore narrowing the number of instructors produced. With that being said, the teaching salaries can improve because of the new demand for this productive style of teaching that K-12 schools would require the employed instructors to have completed during their college career(s). Our future generations upbringing needs to be updated according to the new age that we live in today. Democratic education needs to be a mainstream style of teaching, not for our benefit, but for the future of the precious world that you and I share. This is not a type of thing to be organized and implemented to help certain individuals succeed but for everyone, we need to teach our children that as a country we are a collective, and as individuals we are our own. Democratic education be used as another tool to help us educate the country and create a more successful tomorrow.

10 Day Placement Assignment Analysis From Snap Social Work Essay

10 Day Placement Assignment Analysis From Snap Social Work Essay SNAP is an organisation that was set up in June 2008. It is a collaboration of six organisations Orwell Housing Association, Anglia Care Trust, Epic Trust, Ipswich Housing Action Group, Family Action and Together- Working for Wellbeing. Each employee of Snap is affiliated to one of the main organisations and is an employee of only one of the partners. All six organisations tendered, and won the contract to provide CARA (Central Access Referral Agency) and non accommodation based housing support. The collaboration of the agencies ensures a diversity of skills, knowledge and experience. SNAP is responsible for support throughout Suffolk apart from those in the Waveney area. These referrals come through CARA but are then transferred to Flagship Housing to provide support. SNAPs primary aims are to prevent homelessness, to support people to develop skills that will facilitate independent living and to prevent or assist an individual from being admitted to institutionalised accommodation. The support SNAP provides may be accessed by anyone over the age of 16 as long as they are eligible to receive public funds and have needs that are housing related. SNAP supports people for a maximum of two years, up to three hours a week. The needs and progress of the service user are reviewed every 13 weeks. If the service user still requires support after two years or is deemed to have ongoing requirements then they are referred to other agencies that will provide this. Each organisation that is involved in SNAP, has their own policies and mission statements. The values that SNAP have taken as their own are those of respect, integrity, honesty and trust. There is no mission statement that applies overall, as each employee of SNAP is employed by one of the six agencies, and it is the mission statement of that agency that applies to the individual employee. SNAP has six support planning principles. The first of these is that the support provided is individualistic. This is a traditional social work value originally put forward by Biestek (1961). This value means that the worker should recognise and understand each service users unique qualities and situation and take these into account at all times. SNAP also advocates person centred therapy. This approach originated from Carl Rogers (Rogers, 1942) and is from the humanistic school of psychology. This theory involves the process of providing the service user with unconditional positive regard, empathy and openness as it is these that empower the service user and facilitate their ability to solve their own issues. SNAP works in an inter-professional manner. Referrals received by SNAP are from a multitude of agencies due to the diversity of service users and their needs. SNAP is only able to support those who have difficulties in maintaining a tenancy and anything that does not fall within this remit requires SNAP to signpost the service users to other agencies. Furthermore, the support provided may involve SNAP liaising with other agencies that may be relevant in the service users life. All SNAPs interventions are Task centred (Reid Shyne 1969). SNAPs support is classed as short term even though it can continue for up to two years. Task centred approach to intervention is usually done on a much shorter term basis, usually six weeks. SNAP and the service user both agree their roles and responsibilities during the support; this is in the form of a document that makes clear to the service user and the support worker, what each will do during the support. This is signed by both at the onset of support. This is in line with the task centred approach and makes clear what difficulties need to be addressed and eachs role in doing this. As all of SNAPs service users are experiencing problems with regard to housing, this problem solving approach is both practical and relevant. At each 13 week review, SNAP ensures that progress is being made and the service users needs are reassessed. Some of the referrals that are made to SNAP, involve service users in a crisis situation, pa rticularly if imminent eviction is likely. The task centred approach is similar to crisis intervention (Caplan Lindemann -Kanel, 2003, p.14) although crisis intervention has a more psycho-dynamic approach, promoting psychological growth as opposed to task centred theory, which is more based on the understanding that a crisis provides the motivation to act. Both crisis intervention and task centred approaches involve problem solving. SNAP treats its service user in a non judgemental manner. This is one of Biesteks (1961) traditional social work values requiring that the worker does not judge and neither approve or disapprove of the service user. During my shadowing this has been the case. Due to the nature of SNAPs intervention, being short term housing support, it is difficult to set up committees or long term client groups that have an input into the organisation and how it is run and the future development. However, SNAP do regularly send out questionnaires to service users in order to ascertain whether the service they have received has been useful and whether the service users situation has improved. It has also been suggested that a Mystery Shopper type exercise be undertaken in order to ensure that service users are receiving the best service possible at the point of contact. At each review, the client is asked whether they have been happy with the service they have received from SNAP. They are asked whether their situation has improved, not improved or worsened since support started. They are also asked if they have any suggestions as to whether SNAP could improve their service or whether there is anything that they feel they could do that they are not already doing. It has been decided that as part of my Observational placement task of undertaking an interview with a service user, I will use this part of the review as questions for my placement interview. On an operational level, SNAP is entirely user led, due to its task centred approach. As each client is reviewed on a regular basis, there are opportunities throughout the intervention for service users to be able to give feedback at varying points through SNAPs involvement. It is difficult to give service users a strategic role in the organisational development due to the short term nature of the intervention. Whilst shadowing with the support workers, I saw many examples of good practice. Each support worker that I shadowed with was empathetic and appeared to build good relationships with the service users they were assigned to. They appeared to be non judgemental (Biestek), dealing with sex offenders and expressing a level of sympathy for their inability to rebuild their lives following a conviction. There appears to be high levels of oppression towards the more vulnerable referrals. The benefits agency itself made many service users feel powerless and this was acknowledged by the support workers who then called the agency on behalf of the service users. This was anti- oppressive and illustrated this value to me very clearly. Another area that I will identify as good practice, were the recording of interventions, and contact made with both the service user and others who were connected to them. Each support worker that I shadowed appeared to make an entry on the computer system after every telephone call made and letter sent as well as after every visit. It would appear that this was done; ensuring information regarding each intervention was up to date and complete. This complies with Section 6.1 of the Codes of Ethics that states that: As a social care worker, you must be accountable for the quality of your work and take responsibility for maintaining and improving your knowledge and skills by maintaining clear and accurate records as required by procedures established for your work; Whilst shadowing LC, we found that a service user was going to make a possibly fraudulent Housing Benefit Claim. Once the service user told LH of their intention, LH advised that this would be fraudulent and told the service user that she should not be doing this. The service user stated that she was going to and so LH stated that they would be unable to support the service user if this was the course of action that they intended to take. The service user decided to follow LCs advice. This showed honesty and integrity on the part of LC, in accordance to Section 2 of the Social Work Codes of Practice as well as SNAPs own personal values of integrity and honesty. After being in the office with various support workers, it was apparent that at times there were not enough desks and computer terminals for all those in the office to be able to use. Although this did not happen all the time, it did happen regularly. It may be an idea to perhaps invest in some more. Furthermore, again, not all the time, but regularly, it was not possible to sign into the operating system due to the maximum amount of users being logged on to the computers. I have never seen this IT issue before and it struck me as being unusual. I was advised that more licenses have been purchased so the problem is not as great as it was in the past. Although addressing this issue would obviously alleviate any delays in using the IT, making Snap more efficient and effective, it may not be enough of an issue to warrant the economic investment that would be involved. It could be said that as SNAP is a relatively new company, and with the other established organisations bringing a wealth of knowledge and experience to the table, SNAP is well placed to cherry pick the best practice from each. SNAP appears to be an efficiently run organisation. The staff appear to be knowledgeable and have the best interests of the client in mind. There are clearly defined systems in place at each level of intervention, including the recording of information.

Tragic Hero in The Crucible Essay examples -- The Crucible Arthur Mill

Tragic Hero in The Crucible What is a tragic hero? The most well known definition of a tragic hero comes from the great philosopher, Aristotle. When depicting a tragic hero, Aristotle states "The change in the hero's fortunes be not from misery to happiness, but on the contrary, from happiness to misery, and the cause of it must not lie in any wickedness but in some great error on his part.† In addition, he explains the four essential qualities that a tragic hero should possess, which are goodness, appropriateness, lifelike, and consistency. All of these necessities help to classify the character of John Proctor as the tragic hero of the play. Not only does he unfortunately fall to desolation, but also his character captures the sympathy and pity from the audience or readers. A tragic hero is also known to be someone who brings about their own death, through a flaw within their character or through their actions. Proctor's downfall in the play is initiated by a human error, which to a great extent qualifies him to be the tragic hero. Is John Proctor a tragic hero? In this essay I will be exploring his character, personality, and relationship towards others. The Crucible, written by Arthur Miller, depicts the story of the Salem witch-hunt and the chaos it caused. One of the main characters is John Proctor. Proctor is put through many life-changing decisions. In many cases, a decision he made in one situation led to another problem. Miller sets ‘The Crucible’ in a Puritan community in Salem, Massachusetts, in the spring of 1692. The Puritans were a group of religious separatists who sought to worship God in uncomplicated and basic ways. They built their own houses, made their own furniture, and did... ...himself harshly. Before Abigail came and ruined his peace, he was always sure of himself. After Abigail, he was sure that nothing he would ever do would be pure and honest again. Proctor’s â€Å"tragic hero† status was illustrated by his efforts to save his wife from being put to death, his attempt to prove the children are making fraudulent claims, and his unwillingness to confess to practicing witchcraft when accused. Personally I believe all humans are created with flaws, which control our emotions and often twist our lives. We are put into predications because we are having a hard time of controlling them; therefore we just let them flow. John Proctor’s flaws were his faith, the belief of his own dignity, and his pride, that eventually put in to death. He is a tragic hero that dies of his own flaw, which brought up our sympathy and our fear of death.

Stop Abortions Essay -- Argumentative Persuasive Pro Choice Life Essay

Stop Abortions On January 22, 1973 the court decision of Roe vs. Wade stated that approved processes of abortion are legalized until viability, which is the point at which the fetus is capable of surviving outside the mother’s body. The decision allows individual states to regulate or ban abortion after viability except, however, when necessary to protect the life or physical well-being of the mother (10 Important1). It has been almost thirty years since that solemn day where a nation, built on the natural right of life to all of its citizens, allowed the intentional and legal termination of an unborn child. Immediately after that event, opposition to the newfound law felt that it would have to appeal and overturn the decision within a short time to avoid the practice from becoming infused into the nation too firmly. As years passed the judicial system worsened the situation with less stringent regulations. Almost every third baby conceived in America is being terminated (Willke2). But as time passes America has realized that pro-life supporters are still fighting and making progress. Pro-choice advocates have spelled out many arguments campaigning against pro-lifers and attempting to justify this blatant destruction of a child. I will attempt to nullify the validity of these arguments to the students of State University and display alternatives to this inhumane practice. The decision of Roe vs. Wade on January 22, 1973 has been a terrible burden on the United States and should be seriously reconsidered. Abortion, specifically partial birth abortion, is a malicious act towards a living human that deserves life as much as a full grown adult. Abortion Methods As abortions became more and more prevalent in Ameri... ... of the methods of abortion so adoption should always be considered. Women want to be respected and feel that they have a right to choose as to whether they have a child or not. I say that why can we not respect them both: the mother and child? Why can we not show compassion for these women in this situation and love the child who is at stake as well. We must educate society of the alternatives to benefit all parties involved.

Howard Gardner :: Essay papers, Education

Howard Gardner Howard Gardner is a Professor in Cognition and Education at the Harvard Graduate School of Education. He also holds positions as Adjunct Professor of Psychology at Harvard University, Adjunct Professor of Neurology at the Boston University School of Medicine, and Co-Director of Harvard Project Zero. Among numerous honors, Gardner received a MacArthur Prize Fellowship in 1981. He has been awarded eighteen honorary degrees--including degrees from Princeton University, McGill University and Tel Aviv University on the occasion of the 50th anniversary of the state of Israel. In 1990, he was the first American to receive the University of Louisville’s Grawemeyer Award in education. In 2000 he was awarded a Guggenheim Fellowship. The author of eighteen books and several hundred articles, Gardner is best known in educational circles for his theory of multiple intelligences, a critique of the notion that there exists but a single human intelligence that can be assessed by standard psychometric instruments. During the past fifteen years, he and colleagues at Project Zero have been working on the design of performance-based assessments, education for understanding, and the use of multiple intelligences to achieve more personalized curriculum, instruction, and assessment. Most recently, Gardner and his colleagues have launched the Good Work Project. "Good Work" is work that is both excellent in quality and also exhibits a sense of responsibility with respect to implications and applications. Researchers are examining how individuals who wish to carry out good work succeed in doing so during a time when conditions are changing very quickly, market forces are very powerful, and our sense of time and space is being radically altered by technologies, such as the web.

Factors Affecting Solubility

There are three main factors that control solubility of a solute. (1) Temperature (2) Nature of solute or solvent (3) Pressure EFFECT OF TEMPERATURE Generally in many cases solubility increases with the rise in temperature and decreases with the fall of temperature but it is not necessary in all cases. However we must follow two behaviours: In endothermic process, solubility increases with the increase in temperature and vice versa. For example: solubility of potassium nitrate increases with the increase in temperature. In exothermic process, solubility decrease with the increase in temperature.For example: solubility of calcium oxide decreases with the increase in temperature. Gases are more soluble in cold solvent than in hot solvent. NATURE OF SOLUTE AND SOLVENT Solubility of a solute in a solvent purely depends on the nature of both solute and solvent. A polar solute dissolved in polar solvent. Solubility of a non-polar solute in a solvent is large. A polar solute has low solubil ity or insoluble in a non-polar solvent. EFFECT OF PRESSURE The effect of pressure is observed only in the case of gases. An increase in pressure increases of solubility of a gas in a liquid.For example carbon dioxide is filled in cold drink bottles (such as coca cola, Pepsi 7up etc. ) under pressure. Properties of Solution Concentration The concentration of a solution is the measure of how much solute and solvent there is. A solution is concentrated if it contains a large amount of solute, or dilute if contains a small amount. Molarity Molarity is the number of moles of solute per litre of solution. It is abbreviated with the symbol M, and is sometimes used as a unit of measurement, e. g. a 0. 3 molar solution of HCl. In that example, there would be 3 moles of HCl for every 10 litres of water (or whatever the solvent as). Molality Molality is the number of moles of solute per kilogram of solvent. It is abbreviated with the symbol m (lowercase), and is sometimes used as a unit of me asurement, e. g. a 0. 3 molal solution of HBr. In that example, there would be 3 moles of HBr for every 10 kilograms of water (or whatever the solvent was). Mole Fraction The mole fraction is simply the moles of solute per moles of solution. As an example, you dissolve one mole of NaCl into three moles of water. Remember that the NaCl will dissociate into its ions, so there are now five moles of particles: one mole Na+, one mole Cl-, and three moles water.The mole fraction of sodium is 0. 2, the mole fraction of chloride is 0. 2, and the mole fraction of water is 0. 6. The mole fraction is symbolized with the Greek letter (chi), which is often written simply as an X. Dilution Dilution is adding solvent to a solution to obtain a less concentrated solution. Perhaps you have used dilution when running a lemonade stand. To cut costs, you could take a half-full jug of rich, concentrated lemonade and fill it up with water. The resulting solution would have the same total amount of sugar a nd lemon juice, but double the total volume. Its flavour would be weaker due to the added water.The key concept is that the amount of solute is constant before and after the dilution process. The concentration is decreased (and volume increased) only by adding solvent. Thus, the number of moles of solute before and after dilution are equal. moles1 = moles2 By definition of molarity, you can find the moles of solvent. M x V = moles Substituting the second equation into the first gives the dilution equation. M1 x V1 = M2 x V2 To determine the amount of solvent (usually water) that must be added, you must know the initial volume and concentration, and the desired concentration.Solving for V2 in the above equation will give you the total volume of the diluted solution. Subtracting the initial volume from the total volume will determine the amount of pure solvent that must be added. Ionic Solutes When ionic compounds dissolve in water, they separate into ions. This process is called diss ociation. Note that because of dissociation, there are more moles of particles in the solution containing ions than there would be with the solute and solvent separated. If you have two glasses of water, and you dissolve salt into one and sugar into the other, there will be a big difference in concentration.The salt will dissociate into its ions, but sugar (a molecule) will not dissociate. If the salt were NaCl, the concentration would be double that of the sugar. If the salt were MgCl2, the concentration would be triple (there are three ions). Solubility Rules Not all ionic compounds are soluble. Some ionic compounds have so much attractive force between their anions and cations that they will not dissociate. These substances are insoluble and will not dissolve. Instead, they clump together as a solid in the bottom of solution. Many ionic compounds, however, will dissociate in water and dissolve.In these cases, the attractive force between ion and water is greater than that between cation and anion. There are several rules to help you determine which compounds will dissolve and which will not. Solubility Rules 1. All compounds with Group 1 ions or ammonium ions are soluble. 2. Nitrates, acetates, and chlorates are soluble. 3. Compounds containing a halogen are soluble, except those with fluorine, silver, or mercury. If they have lead, they are soluble only in hot water. 4. Sulfates are soluble, except when combined with silver, lead, calcium, barium, or strontium. . Carbonates, sulfides, oxides, silicates, and phosphates are insoluble, except for rule #1. 6. Hydroxides are insoluble except when combined with calcium, barium, strontium, or rule #1. Sometimes, when two different ionic compounds are dissolved, they react, forming a precipitate that is insoluble. Predicting these reactions requires knowledge of the activity series and solubility rules. These reactions can be written with all ions, or without the spectator ions (the ion that don't react, present o n both sides of the reaction), a format known as the net ionic equation.For example, silver nitrate is soluble, but silver chloride is not soluble (see the above rules). Mixing silver nitrate into sodium chloride would cause a cloudy white precipitate to form. This happens because of a double replacement reaction. Electrolytes When solutes dissociate (or if a molecule ionizes), the solution can conduct electricity. Compounds that readily form ions, thus being good conductors, are known as strong electrolytes. If only a small amount of ions are formed, electricity is poorly conducted, meaning the compound is a weak electrolyte.A strong electrolyte will dissolve completely. All ions dissociate. A weak electrolyte, on the other hand, will partially dissociate, but some ions will remain bonded together. Colligative Properties Some properties are the same for all solute particles regardless of what kind. These are known as the colligative properties. These properties apply to ideal solut ions, so in reality, the properties may not be exactly as calculated. In an ideal solution, there are no forces acting between the solute particles, which is generally not the case. Vapor PressureAll liquids have a tendency for their surface molecules to escape and evaporate, even if the liquid is not at its boiling point. This is because the average energy of the molecules is too small for evaporation, but some molecules could gain above average energy and escape. Vapor pressure is the measure of the pressure of the evaporated vapor, and it depends on the temperature of the solution and the quantities of solute. More solute will decrease vapor pressure. The vapor pressure is given by Rauolt's Law, where X is the mole fraction of the solvent.Notice that the vapor pressure equals that of the pure solvent when there is no solute (X = 1). If X = 0, there would be no vapor pressure at all. This could only happen if there were no solvent, only solute. A solid solute has no vapor pressure . P solution = P pure solvent (X solvent) If two volatile substances (both have vapor pressures) are in solution, Rauolt's Law is still used. In this case, Rauolt's Law is essentially a linear combination of the vapor pressures of the substances. Two liquids in solution both have vapor pressures, so this equation must be used. P solution = P1 (X1) + P2(X2)The second equation shows the relationship between the solvents. If two liquids were mixed exactly half-and-half, the vapor pressure of the resulting solution would be exactly halfway between the vapor pressures of the two solvents. Another relation in Henry's Law, which shows the relationship between gas and pressure. It is given by Cg = k Pg , where C is concentration and P is pressure. As the pressure goes up, the concentration of gas in solution must also increase. This is why soda cans release gas when they are opened – The decrease in pressure results in a decrease in concentration of CO2 in the soda.Boiling Point Elev ation A liquid reaches its boiling point when its vapor pressure is equal to the atmosphere around it. Because the presence of solute lowers the vapor pressure, the boiling point is raised. The boiling point increase is given by: ?T solution = Kb X m solution The reduced vapor pressure increases the boiling point of the liquid only if the solute itself is non-volatile, meaning it doesn't have a tendency to evaporate. For every mole of non-volatile solute per kilogram of solvent, the boiling point increases by a constant amount, known as the molal boiling-point constant (Kb).Because this is a colligative property, K2 is not affected by the kind of solute. Freezing Point Depression A liquid reaches its freezing temperature when its vapor pressure is equal to that of its solid form. Because the presence of the solute lowers the vapor pressure, the freezing point is lowered. The freezing point depression is given by: ? T solution = K f X m solute Again, this equation works only for non- volatile solutes. The temperature of the freezing point decreases by a constant amount for every one mole of solute added per kilogram solvent. This constant (K f) is known as the molar freezing-point constant.Osmosis If you studied biology, you would know that osmosis is the movement of water through a membrane. If two solutions of different molarity are placed on opposite sides of a semipermiable membrane, then water will travel through the membrane to the side with higher molarity. This happens because the water molecules are â€Å"attached† to the solvent molecules, so they cannot travel through the membrane. As a result, the water on the side with lower molarity can more easily travel through the membrane than the water on the other side. The pressure of this osmosis is given in the equation. ? = MRTWhere pi is the pressure, M is molarity, R is the gas constant, and T is temperature in Kelvin. Electrolytes and Colligative Properties When one mole of table salt is added t o water, the colligative effects are double those that would have occurred if sugar were added instead. This is because the salt dissociates, forming twice as many particles as sugar would. This dissociation, called the Van't Hoff Factor describes how many particles that are dissociated into the solution and must be multiplied into the Boiling Point Elevation or Vapor Pressure Lowering equations. Different ways of expressing the concentration of solutionsMass Percentage The mass percentage of a component in a given solution is the mass of the component per 100g of the solution. For e. g. , if WA is the mass of the component A, WB is the mass of the component B in a solution. Then, Example: A 10% solution of sodium chloride in water (by mass) means that 10g of sodium chloride are present in 100g of the solution. Volume percentage This unit is used in case of a liquid dissolved in another liquid. The volume percentage is defined as the volume of the solute per 100 parts by volume of s olution. For e. g. , If VA is the volume of component A present is Vsol volume of the solution.Then, For e. g. , a 10% solution of ethanol C2H5OH, in water (by volume) means that 10cm3 of ethanol is present in 100cm3 of the solution. Strength of a solution is defined as the amount of the solute in gms, present in one litre of the solution. It is expressed as gL-1. Mathematically, Molarity Molarity of a solution is defined as the number of moles of solute dissolved per litre of solution. Mathematically, For e. g. , If ‘a' is the weight of the solute (in gms) present in VCC volume of the solution. Then, Molarity is expressed by the symbol M. It can also be expressed as, NormalityNormality of a solution is defined as the number of gram equivalents (gm. e) of a solute dissolved per litre of the given solution. Mathematically it is, For e. g. , If a is the weight of the solute (in gms) present in VCC volume of the solution. Then, Normality is expressed by the symbol N. It can also be expressed as, Relationship between molarity and normality The molarity and normality of a solution is related to each other as follows: Molality Molality of a solution is defined as the number of moles of solute dissolved in 1000g of a solvent. Mathematically, it is expressed as Molality is expressed by the symbol m.Molality does not change with temperature. Formality In case of ionic compounds like KCl, CaCO3 etc. Formality is used in place of molarity. It is the number of gram formula masses of solute dissolved per liter of the solution. It is denoted by the symbol F. Mathematically it is given as, Mole Fraction It is the ratio of number of moles of one component (solute or solvent) to the total number of moles of all the components (solute and solvent) present in the solution. It is denoted by the symbol X. Let us suppose that a solution contains two components A and B and suppose that nA moles of A and nB moles of B are present in the solution then,Adding eq (i) and (ii) we g et XA + XB = 1 Parts per million (ppm) When a solute is present in very small amounts, its concentration is expressed in parts per million. It is defined as the amount of the solute present in one million parts of the solution. It may be noted that the concentration units like molarity, mole fraction etc. are preferred as they involve the weight of the solute and solvent, which is independent of the temperature. But units like, molarity, normality etc. , involve volume of the solution, hence changes with temperature.

Mostly used for medical purposes or in areas with scarce or no oxygen like under water or at high levels above the ground i.e. aerospace.Medically, oxygen gas is used in the treatment of gas poisoning, pneumonia, used as an anesthetic when mixed with nitrous oxide or administered in deficiency of oxygen (Rees, Dudley, 2006).Liquefied oxygen is pale blue in color, and has a density of 1.141g/cm3. The liquid has a boiling point of -182.96oC and a freezing point of -222.65oC. Its raw material is oxygen which is obtained from natural air by a process know as fractional distillation.   At 20oC the liquid gas has an expansion rate of 860:1 (O'Leary, 2000).Fractional distillation is done in a factory with boilers this makes the laborers to work at very cold environments which are highly flammable. Natural air is made up of different gases which has different evaporation or freezing points. The natural air is first liquefied t o be liquid air which has a mixture of liquid nitrogen and liquid oxygen with boiling points of (-196oC) and (-183oC) respectively.Liquid air is heated to -183oC which oxygen evaporate, it’s tapped and liquefied again now as Oxygen liquid which is then packed in high pressure cylinders for distribution. Most of the cylinders meet minimum requirements of weighing 5 pounds and under and usually last up to 5 hours or more (Portableoxygen, 2009). The cylinders administer oxygen in pulses through a device know as a conserver which delivers a pulse of oxygen when the user inhales.Ethical considerations of the product are; the liquefied gas is highly explosive and flammable hence it use for industrial purposes. Due to its properties of being highly flammable and explosive some people mix it with powdered charcoal to make explosives which are lethal.The product should be produced the way its being done but its distributions should be controlled and sold only to authorized dealers and users to minimize its use to prepare explosives.ReferencesO'Leary, D.

Father Son Conflict in Death of a Salesman and All My Sons

In the sass, French philosophers such as Roland Farther, Gilles Delude, Jacques Deride, Michel Faculty, and Jean- Franà §ois Leotard departed from conventional studies in the history of philosophy and Egan to address the epistemological crisis reinforcing Western philosophical thought. Their early scholarship focused on the structure of language and its role in forming world-views. The work of the Swiss linguist Ferdinand De Assures, especially his posthumous text entitled Course in General Linguistics, presented the Intellectual Insight Tanat was necessary In order to separate ten synchrony Ana diachronic elements of language.Dividing language and, in effect, freeing the sign from the signified, permitted obstructionists to redefine language as a system of differential signs. Jacques Dermis's early writings obfuscate Creature's linguistic turn. Deride could not stand the fact that the Western philosophical tradition privileges spoken (the sonic) over written language (the graphic). It is within this pyramid that the speaker is accepted to be self-authenticating and in control of meaning. The writer, within this representation, is displaced and, presumably, is not in control of meaning.Assures, according to Deride, continues the Western tradition by giving more importance to the spoken word over the written word. Deride describes this as phonetics's, a oppression of writing. His work seeks to invert the hierarchy and so present writing as a necessary displacement of meaning within language. Dermis's innovative variations on Creature's linguistic turn inaugurated postmodernism sustained dismantling of the metaphysics of presence in the Western philosophical tradition. Dermis's critique of language was followed by critiques of truth and meaning in philosophy.Drawing on the work of the German philosopher Frederica Nietzsche, Deride has disrupted the visualized belief that authors intend meaning and that there is a certain truth to be uncovered in texts. Deride, i n the Nietzsche tradition, views philosophy not as a search for truth, but as a rhetorical engagement with the world. Truth and meaning are not fixed: they are metaphorical. Others have extended Dermis's insights to the study of culture, literature, politics, and psychoanalysis, and, indeed, the displacement of meaning and truth characteristic of postmodernism has proved relevant to diverse academic disciplines.Cast in the best possible light, postmodernism challenges hierarchies and presents a multiplicity of interpretations with an optimism that is not shared by the majority of scholars. Postmodernism anti-foundations is often linked to, if not actually equated with, the logic of late capitalism (Frederic Jameson) and political conservatism. Emphasis on epistemological undesirability and the loss of the subject appears to have persuaded many scholars to view postmodernism as nihilistic and irrational.Nevertheless, postmodernism has come to be considered a significant endeavor in c ulture studies. The French philosopher Jean-Francis Leotard has articulated postmodernism within the aesthetic and political spheres. Leotard's postmodernism critiques the totaling tendency of modernity's monolithic world-views. Where there is completion and unity in modernism, one finds deferment and fragmentation in postmodernism. Leotard's major contribution toward a definition of postmodernism is his theory of intransitives.Modernity, according to Leotard, privileges all- encompassing narratives such as fascism, Marxism and capitalism. Leotard's postmodernism encourages little narratives that claim to avoid utilization and preserve heterogeneity. Leotard's challenge to the tendency to conceptualize history as events in a linear sequence means that, for him, postmodernism never can be represented in language or in history. Postmodernism for Leotard is neither a style nor an historical period. Instead, postmodernism is an unrepeatable deferment of conceptualization and totality.Th is is coming from us. And we have not come close to even confronting this thing† (CTD. In Abbots, 2007: 94). Miller by his drama conveys the necessity of a humanistic response to the contemporary world. Such a description closely resembles the objectified picture the postmodern critic, Jameson, creates of contemporary society, where he announces the death of individualism, â€Å"symbolized by the emergent Anoraks Hoot; Profaner Zipper/Studies in Literature and Language Volvo. L No. 8, 2010 primacy of mechanical production† (1991 5), by which all becomes identical and exists without individual identity, choice, or spirit.Miller carefully criticizes the consumer society and its capitalist logic. In fact Wily himself as salesman uses the language of advertisement to earn money. But this consumer world has harsh rules; it exploits everybody and as Wily affirms: â€Å"eat the orange and throw the peel away'(Miller: 61) although † a man is not a piece of Trust† ( 61 In Tact man must struggle Tort survival In a consumer collect, wanly Is Like a consumer industry produces not things, but dreams disguised as things. Wily by the harsh machinery of the contemporary consumer world is beaten down.He cannot get up back. Linda exhorts â€Å"But he's a human being, and a terrible thing is happening to him. So attention must be paid†(40). Wily is the victim of the American Dream and materialistic condition. Wily loan's condition is so close to everybody in the consumer world that develops a sense of kinship to each person. He makes the audience aware of a common fatality and vulnerability. The society that Wily belongs to, is the business world. His boss, Howard, is the representative of the business world, which rejects Wily.Unwilling to accommodate Will's inability to travel anymore, Howard says, â€Å"No, but it's a business, kid, and everybody's goat pull his own weight† (60). Indeed Wily is born as a salesman. Murphy defines this ide a: In the scene between Wily and Howard, he nearly sells Howard on the myth of Dave Signalman before he sabotages his sales pitch by losing his temper. Wily Leman is a very confused man, but his confusion about what it means to be a salesman and what it takes to succeed at the Job is as much cultural as personal (CTD In Abbots, 2007:108).Wily is fired, in the end, not because a hard-nosed employer wants to eat the fruit and throw away the peel but because Wily cannot even sell himself. Bigly(2005) describes Wily Leman â€Å"as agent of an intrusive commercialism victim ND martyr creature touchingly, tragically doomed by the business culture he represented but which also leaves him as solitary figure in the social landscape†(110). In the contemporary consumer world the problem of postmodern man is, he is not being himself. He becomes vehicle for participation in a cycle of production and consumption.He sells a commodity and becomes a commodity. When man thinks he can acquire e verything, material or immaterial by buying it, he regards his personal qualities and the result of his efforts as commodities that can be sold for money. Thus man misses the experience of the activity of the present moment and chases the illusory happiness called success. There are many like Wily, who put all their faith in personality, friendship, and personal loyalty-?†Be liked and you will never want† (Miller: 21), but by coming a new way of thinking about salesmanship everything has changed.Mass production and consumer culture have begun to alter his business economy, therefore, salesmanship has been treated as a profession to be learned. With mass production and increasing competition, buyers and merchants have begun to think more about profit. Murphy s idea about competition is interesting: With the stock market crash in 1929, and the Great Depression that followed it, the competition among salesmen became more and more cutthroat.As Wily tells Ben in one of the da ydream sequences that takes place in 1931, business is bad, it's murderous . Using all of the tricks that Wily has learned in a lifetime of selling, including seducing the buyer's secretary and bribing her with stockings, Wily is barely able to eke out a living for his family (CTD In Abbots, 2007:110). But during this period, the prevailing idea was still that, as Wily puts it, â€Å"the man who sakes an appearance in the business world, the man who creates personal interest, is the man who gets ahead† (21).According to Murphy: in the post-war period, there was a pent-up demand for things like new cars, tires, Dragon-name liquor, Ana nylon stockings, wanly Ana not Eden available ruling ten war. The enormous war industry was being retooled to produce consumer goods, and the advertising business was expanding rapidly as Americans were â€Å"educated† into desiring things like Anoraks Hoot; Profaner Zipper/Studies in Literature and Language Volvo. L No. 8, 2010 vacuum cle aners, television sets, and air conditioners, which had not been manufactured in large quantities before the war. CTD. In Abbots, 2007:111). Death of a Salesman does not simply show the predicaments of the modern man stuck in a postmodern world, but also displays the conflicting views of these two worlds. Bigly(2005), suggests: Wily Loan's American dream is drained of transcendence. It is a faith in the supremacy of the material over the spiritual. There is, though, another side to Wily, a side represented by the sense of insufficiency that sends him searching through his memories looking for the origin of failure, looking for expiation.It is a side, too, represented by his son Biff, who has inherited this aspect of his sensibility, as Happy has inherited the other. Biff is drawn to nature, to working with his hands. He has a sense of poetry, an awareness that life means more than the dollars he earns. Wily has that, too. The problem is that he thinks it is irrelevant to the imperat ives of his society and hence of his life which, to him, derives its meaning from that society (105). The Leman family is caught up in mindless consumerism, â€Å"whipped cheese† (6) and that these new products disrupt attempts at meaningful human interaction.Shockley states: Miller shows the power of advertising and consumerism, and the contradictions of attitudes toward products in the Leman family by having Wily call his Chevrolet both â€Å"the greatest car ever built† and â€Å"that goddamn Chevrolet† in the space of only a few minutes, and in Willis remark that â€Å"Once in my life I would like to own something outright before it's broken! † But while Wily utters these remarks, he still is completely caught up in the pursuit of the dream. (CTD. In bloom, 2007:86) I HAVE MONEY THEN I AM In Death of Salesman the Becoming of man is weighed through his bank balance.It is the strength of his bank account, which accordingly mirrors the importance of his existence as a being. The alienation that the industrial era brought upon men is witnessed in the character of Wily Leman. Through this alienation, Will's connectivity to society is severed and his tie to moral responsibility on behalf of mankind is weakened greatly. He brushes with the uglier side of capitalism, and yet seemed unable to recognize or condemn this brutal side. Shockley asserts: In competitive society the rewards of being successful for Wily is to be well liked and to be rich.To be rich also means to be â€Å"free† in the two senses above, with the added goldfinches of being admired, a model for others (CTD. In Bloom,2007: 84). Miller in Death of a Salesman gives the bitterest satire on human condition in contemporary century. He writes about demutualization result from Enlightenment. Miller criticizes the universal values of Enlightenment humanism. In the capitalism society, consumer culture shows the end of Grand narratives and western metaphysics, which brin g tremendous rifts and disintegration among people. Wily represents the reduction of

Corporate Responsibility and Marketing Strategies Essay - 2

Corporate Responsibility and Marketing Strategies - Essay Example Its marketing strategy is decent but there is room for improvement. Even so, its reputation has been hurt because of violation of not only its code of conduct but also other laws (Klein 2011). This has been detrimental, but Apple is trying its best to make right the situation. Apple Corporation has a code of conduct that sets out its suppliers’ ethical and social responsibility. On its website, it outlines that suppliers ought to treat workers in an ethical manner and fairly at all times. In addition, each worker has the right to healthy and safe work area, it integrates environmental responsibility into its processes and products, and that it goes deep into the supply chain in order to enforce its standards and solve problems (Apple Inc., 2014). Despite having a code of conduct, Apple has not met these responsibilities effectively. For instance, Kaiser (2012), reports that Foxconn, the main supplier of Apple located in China, subjects employees to long working hours, they are paid peanuts and work in conditions that are unsafe, all for the mere reason of prompt assembling of iPods, iPhones and iPads. Additionally, the supplier also releases its waste into sewages, a contravention to its environmental responsibility. These violations have been detr imental to Apple, especially with the lack of an elucidation. Publication of the violations against ethical and social responsibilities occasioned by Apple’s suppliers has been detrimental. After hiring an external organization to conduct an investigation into the allegedly forceful overtime, destitute working conditions, and child labor in its suppliers in the Chinese market, the investigation confirmed the allegations and they were included in the company’s annual reports. Besides, the New York Times released a report after investigating the company and finding that its American workers

Unit VI project domestic terrorism Research Paper

Unit VI project domestic terrorism - Research Paper Example For a period spanning to almost two decades, Theodore John Kaczynski waged a solitary terrorist war in United States of America. He is a former professor of mathematics in Harvard and Berkeley. According to reflections of his childhood as presented by his family, the Unabomber preferred solitude. Nonetheless, his IQ was regarded above genius, a condition that presumably led him to win a scholarship to study at Harvard when he was aged 16 years. His solitary preference became evident at age 26 when he relinquished his teaching duties at Berkeley University. He suddenly isolated himself from the society (McCann, 2006). Kaczynski rolled out his first attack three days immediately after his 36th birthday. He used letter bombs to target university professors in the field of computer science, engineering and biology. He also targeted the owners and managers of airlines. In a given case, Ted aimed at hitting a businessman who ran a small computer store. To scare away investigators, he used pieces of small of his bombs marked with the initials FC. FC is the initial for Freedom Club, which is the infamous terrorist group objecting all forms of scientific and technological advancements (McCann, 2006). Essentially, Kaczynski wanted to pass a message that he was opposed to technological advancements. According to the tip received from his brother, David, Ted’s Manifesto was entitles Industrial Society and its Future. It claimed strong attachment with anarchists and the environmentalists who objected the application of technology in the production processes. His specific targets were businessmen, scientists as well as innocent people. Several accounts of terrorist charges were leveled against him following his arrest in 1996 including 16 letter bombs that ended up killing three people and injuring 29 more. A massive manhunt was set-up in pursuit of the Unabomber. It is

Biology and the body - Essay Example l to explain that the female anatomy has been made to support this model where the Vagina is an interior penis, the uterus is the scrotum and the ovaries are the testicles (Laqueur 28). However, this theory of one sex is criticised especially on the womb, which in the ancient times was thought to be the belly, which was common to both men and women. Another theory that Thomas Laqueur put forward and that followed the one sex model is the two sex theory says that the body determines the gender disparities and the female has a completely different anatomy from a male with dissimilar parts of the anatomy functions and feelings. He explained that there is no sex is a monopoly, Laqueur further went ahead and argued that science would only invent new ways of speaking and not to liberate one gender from another, he put out that destiny is anatomy. The film is it a boy or a girl that Phyllis Ward of the intersex society of North America advocates for intersex people goes into deeper analysis on what biologically determines the gender of an individual. The biological differences between the genders help us further understand how the sex of an individual, which is biologically determined before birth, enables one to play his gender role. For instance, what causes a woman to be a woman biologically and how she is wired to perform the activities that involve the gender and her role in sexual intercourse due her having a vagina. The body is at the centre of any understanding regarding gender as the various anatomical processes in the body determine the gender and the anatomical role the gender plays. However according to the one sex model that there exists a monopoly of gender and that the woman was an imperfect man, then it would be accepted that for a man the larger or bigger the penis is the manlier he is presumed to be. However, that idea is fallacious since even in those times of philosopher Aristotle they preferred a small penis, which was thought of as having a higher

Modernity and Spaces of Femininity Essay Example | Topics and Well Written Essays - 1000 words

Modernity and Spaces of Femininity - Essay Example The paper "Modernity and Spaces of Femininity" focuses on the article of Griselda Pollock. The article clearly represents Pollock’s feminist views. She is a credible author being a leading cultural theorist. She has done vast research on feminist issues such as those that women encounter while living and working in societies as objects of male satisfaction rather than as important subjects that gives credit to their own abilities as women. Pollock has recommended ways to change future representations of women. She has likewise provided significant insights on voyeuristic art and ties between art and human nature. She has become an activist using a â€Å"Marxist-socialist approach to reveal the key sexual and political biases involved in the formation of the modernist movement". Currently, she is the Director for the Centre for Cultural Analysis, Theory and History at the University of Leeds with a Masters Degree in History of European Art and a PhD degree in the study of appr oaches to modernism. She is considered an academic jewel, having taught History of Art and Film in the Universities of Manchester and Leeds and an author of several books on her expertise on Art, History, Feminism and Modernism. In the article, Pollock refers mostly to paintings of renowned artists in the nineteenth century and how their work affected its viewers. She analyzed T.J. Clark’s accounts of Edoard Manet’s controversial painting, â€Å"Olympia† which shows a nude woman reclined on a bed with her hand covering her crotch., with a black lady, presumably her maid, standing beside the bed and a black cat seated at the foot of her bed. This painting was widely criticized when it was exposed to the public, and its analysis runs from shallow comments about its physical appearance to deeper critiques about societal representations during its time. Clark claims that Manet’s Olympia has been the founding monument of modern art3, embodying a shift in what spectators are accustomed to viewing and was subjected to a wide variety of interpretations. Pollock contends that Clark leans on the class system in analyzing modernist paintings. For him, Olympia’s nakedness in Manet’s ‘modernist’ painting depicted her as a lowly prostitute as opposed to heavily dressed, sophisticated and fashionable women in other paintings ascribed as coming from upper classes of society. Pollock also agrees with Clark that such artwork of women catered to a masculine audience since it provokes sexual titillation which is not expected of decent women viewers. This is what she meant by ‘masculinist myth of modernism’. Male artists reigned over modernism because they are able to express their sexuality through their art, which was not a luxury granted to women artists. Pollock confirms that there was a historical asymmetry in art in the nineteenth century due to social structuration of sexual differences which determined wha t men and women painted4. Clark indexes impressionist paintings to class formations and class identities that emerged in society, giving ‘modernity’ a wider meaning than just being up-to-date. â€Å"Modernity is a matter of representations and major myths- of a new Paris for recreation, leisure and pleasure; of nature to be enjoyed at weekends in suburbia; of the prostitute taking over and of fluidity of class in the popular spaces of entertainment†5 References were pointed to Charles Baudelaire’s essay about the modern artist being a flaneur or â€Å"
