That which is accepted as knowledge today is sometimes discarded tomorrow - Essay Example Whether in primary or middle school, the true purpose of education has lost its significance to a great extent as people seem to have forgotten that education is intrinsically linked with acquisition of knowledge. (Davidson and Carber, 2009, p.9) During the formative years, the students traverse through different stages of development and the educational programs that they are taught are not similar as that of middle schools, but one of the most significant aspects of PYP or Primary Years Program is to inculcate the idea of inquiry although it is doubtful whether the educators make genuine efforts for developing the stance of inquiry (Davidson and Carber 2009, p.11). Moreover, the teachers are concerned with the completion of curriculum that robs the children of their natural abilities of expression. For instance, if a child is unable to grasp the concept of ‘transparent’ in the classroom, a teacher may or may not prefer to take special efforts to think of a better way to solve this problem although the principles of teaching reinforce this concept. Thus, knowledge remains unfinished in most schools from early childhood and children may never learn to ask questions even during the latter years when they grow up to become adults. Knowledge, as it is known to us remains a maxim that looks good in text books and it is a fact that few people will be able to abolish when viewed in today’s perspective. The most common example that can be cited for explaining the redundancy of knowledge is that of computer education, which is now being taught in most schools and colleges. It is undoubtedly true that the world of computers, which is developing faster than a sudden storm, leave the learners in awe. Moreover, the parents are puzzled with the inclination among most children to choose computer as their chosen subject. Additionally, the computer programs and curriculums that are taught in

Chemical vapor deposition- principles and implementation Research Paper

Chemical vapor deposition- principles and implementation - Research Paper Example CVD has wide applications which include provision of wear and corrosion resistance, formation of barriers and net shape components. INTRODUCTION Chemical Vapor Deposition (CVD) is a versatile technique of applying required coats of metals on surfaces of components. Unlike other types of painting techniques, this technique applies a coat of the wanted solid on all the accessible surfaces of a component. This therefore makes this technique very appropriate for coat application on surfaces which are of unorthodox nature. In this report, the principles and implementation of CVD are examined. In examining the principles of CVD, the CVD process is closely examined by specifically discussing what takes place inside the reaction chamber of a CVD reactor. The types of CVDs are also discussed. On the second part of this report, the implementation of CVD is discussed whereby the complete equipment set for typical CVD set up is examined. The types of CVD reactors and the applications of CVD are also discussed. PRINCIPLES OF CVD Under this section, the principles of CVD are examined. Specifically, the CVD process is discussed and types of CVDs are also examined. CVD Process The basic principle of the CVD process is the reaction of gaseous precursors to form a solid coating on a heated substrate (ATL 1). This process takes place in the reaction chamber located inside the CVD reactor. ... The temperature will depend on the level of coating required, the gaseous precursors involved and the substrate type. After the substrate has been heated to the required temperature, a controlled gaseous precursor (from the left in the above diagram – Fig. 1) is introduced into the gas chamber. The type of gaseous precursor to be used will depend on the type of deposit required. Figure 2 (ULTRAMET 1) For illustration purpose if metal M is to be deposited on the surface of a substrate, then a gaseous precursor such as MCl2 can be used. It is imperative that the precursor has to be in a gaseous form. After introducing a controlled flow of MCl2 gas, a controlled flow of hydrogen is also introduced. The mixture conditions are adjusted in such a manner that the mixture only reacts when in contact with the substrate surface (ATL 2). MCl2 + H2 = M + 2HCl The reaction on the surface of the substrate releases the metal atom and exhaust gas hydrogen chloride. The metal atom is bonded on the surface of the substrate while the waste gas is drawn out of the reaction chamber by use of a vacuum pump. In the schematic diagram above (Fig 1) the gas is removed to the right. The vacuum pump creates a constant flow of reacting gases into the chamber and waste gases out of the chamber (ATL 3). At the start of the reaction process, the metal deposition is localized (deposited on particular points on the substrate) but as the process progresses the atoms are evenly deposited all over the surface of the substrate. The deposition of the metal applies to all the accessible surfaces of the substrate no matter what shape the substrate has. The process is allowed to progress until the desired thickness of the metal is achieved. In some cases the coating is left to

Principle Of Equality In Practical Ethics Philosophy Essay

Principle Of Equality In Practical Ethics Philosophy Essay The principle of equality in Singers work can be rationally defended from many perspectives, especially when it is being applied to human beings. However, Singer goes further to consider all animals as well. It is the basic assumption of the current investigation that Singers ideas about equality are much more rational, and much less radical, when they are employed to describe human beings; however, when they are expanded to include all sentience, some of the supposed equalities Singer proposes are no longer rational. Some of Singers theories about equality can therefore be challenged by logic, and not accepted, by people who, for example, see a difference between animals and humans, in terms of the equality applied and implied to them. When Singer talks about equality, he rejects the traditional Rawls-influenced notion of moral personality and human equality. Singer proposes a broader and more collectivist ethics, and therefore his idea of equality is also broader. However, there needs to be an alternative to this philosophy because it is untenable and seeks a level of sophistication which the author frequently is unable to convey appropriately, as seen by his use in the following sentence of creative semantics within their rhetoric. The day may come when the rest of the animal creation may acquire those rights which never could have been with-holden from them but by the hand of tyranny (sic). The French have already discovered that the blackness of the skin is no reason why a human being should be abandoned without redress to the caprice of a tormentor (Singer, 1989). Singers essay, which proposes to have a utilitarian argument structure, is basically all about morality, and it corresponds to the rightness or wron gness of an action that impacts that actions significance in terms of utility. This concept of utility has been stretched and formed the main basis for those who would criticize Singers embrace of the equality of animals and humans, as a dry and humourless statistical impossibility that drained the imagination out of humanity and based impulse on quasi-scientific ethical propositions. This is a valid criticism in the light of various authors use of utilitarianism, but it is also important to keep in mind that utilitarianism is basically a positive principle that lays out a plan for happiness, not equality. In other words, there are bright and dark sides to this issue, in which the philosophy can be changed and develop a more hybrid definition as it is interpreted by different scholars, such as Singer, or Bentham. In these cases, one scholar usually comes before the other. Singers ideas of equality also have a lot to do with the equal consideration of disparate interests. From this perspective, the philosopher can be rationally defended by those who seek to end the reign of racism, sexism and discrimination on the grounds of disability, from society. From an egalitarian perspective then, Singer can be rationally defended in his conception of equality, as it is basically a parallel of the status quo of most industrialized societies, at least in principle. And Singer asks thought provoking questions about the nature of real equality, for example, asking reasonably if any readers would really consider a strangers family to be equal to theirs, if both were under some external threat. Some of the more utilitarian of Singers defences of equality seem to make more rational sense than his defence of animals being equal to humans. Singers utilitarianism has a political and legal value, even in the justification theory perspective, because it can separate levels of harm caused to society in terms of either rules that encompass actions or actions which in themselves become rules. It is difficult to say which interpretation is more faithful to the basic tenets of utilitarianism, but it seems that in terms of alternatives, Singer has chosen not to look deeper into this philosophy than just one counts as one. What can be said, however, is that, justification-theory utilitarianism as stressed by Singer, consists of a doctrine that relates to moral goodness rather than ethical goodness, and also a doctrine that relates to what the author believes is morally right, not ethically right. The originators of utilitarianism, Mill and Bentham, both saw utilitarianism as a moral theory, and this is correct, and therefore the author uses the moral theory to back up their own moral philosophy. Jeremy Bentham incorporated the essential basis of moral equality into his utilitarian system of ethics in the formula, Each to count for one and non for more than one. In other words, the interests of every being affected by an action are to be taken into account and given the same weight as the like interests of any other being (Singer, 1989). In utilitarianism, deliberation can be conflated with intention and determination, whereas justification can be thought of as proven reasonability. There are differences between different categories of the philosophy in general, which are basically involved with the application of theoretical concepts in terms of predicting and justifying consequences and comparisons. So equality of opportunity is not an attractive ideal. It rewards the lucky, who inherit those abilities that allow them to pursue interesting and lucrative careers. It penalizes the unlucky, whose genes make it very hard for them to achieve similar success (Singer, 1989). When the author is talking about humans, he makes some cogent points. Singer uses utilitarianism as a theory of justification of society and equality of people and animals, but I would also propose that the author looks a little further into utilitarianism and sees that it is really more about proven reasonability as a standard measuring the worth of the end result or consequential result of the concept: happiness, not equality. In terms of institutional application in a historical sense, this has also included a reckoning of the main points of justification theory utilitarianism as a way of grading or categorizing institutions or policy ramifications in terms of testing and proving the efficiency or utility of the institution through a utilitarian viewpoint. This involves justification in that it uses proof and rationalization rather than deliberation theories of intention and determination. This also increases the value of objectivity as a vaunted standard within utilitarianism, seen from this justification perspective. Singer also examines some inequalities that plague society. The important point is that affirmative action, whether by quotas or some other method, is not contrary to any sound principle of equality and does not violate any rights of those excluded by it From this point, Singers theories view inequality as being passed on from one generation to another in terms of wealth and privilege within a family structure that is seen as a space of economic restriction that also works to keep disadvantaged families in the same place from generation to generation. The social class of the parents, from this perspective, will play a large role in the development of their children in terms of advantages or disadvantages that are inherited in the family structure. From this view, society is not seen as the large organism or field of struggle that functional theorists and conflict theorists see it as, but rather is seen more limited in terms of individual and everyday relations. When Singer is proclaiming the equality of animals and humans, this is a controversial subject on which some of his arguments appear less logical. It has been suggested that autonomous, self-conscious beings are in some way much more valuable morally significant, than beings w ho live from moment to moment, without the capacity to see themselves as distinct beings with a past and a future (Singer, 1989). Everyone has their own ethics. Socially positive behaviour may be influenced by moral behaviour, which has a more religious semantic connotation, but ethics should not be confused with moral behaviour. Ethics is not the same as morality or presupposing moral censorship, as some would have it; morality is more of an externalized and often conditioned response, whereas ethics could perhaps be more readily likened to the basic conscience mechanism of social responsibility. Ethics is something that begins with the individual and acts effectively to represent society in terms of fair and balanced information being presented. Animals do have rights. Those who abuse or are cruel to animals can be brought before the law. But there is also a double standard, because the cows supplying McDonalds hamburgers are mistreated and abused every day in a cruel manner, and no one takes a second thought. Animals do have rights, but they are rights that are determined by humans, not animals. When Singer is talking about the equality of humans who are disabled, or minorities, it is a conventional, status quo argument. But when he suggests the equality of animals and humans, he takes a step towards more controversial polemics. (Singer, 1989)

Modern Aboriginal Issues Essay -- Aboriginals Australia History Essays

Modern Aboriginal Issues The first Europeans to settle Australia treated the Aboriginals in a brutal, unfair manor. They downgraded Aboriginals to a lower status as human beings. They tried to force the Aboriginals to conform to the western way of life for more than 200 years. It is only fairly recently that the Aboriginals have finally been able to gain back some of their indigenous rights and traditions. Yet they are still deficient in many areas. The land that their ancestors held has not all been returned to them, they struggle to meet the requirements of western education systems, and they have a very limited access to health care. In spite of these problems, many aboriginals are working to better themselves and their community. It will just take time for the western and Aboriginal cultures to merge into the one final Australian society Introduction The Aboriginal people have undergone much change and turmoil in the 220 years since the British first started a colony. They have seen their land and their freedom stripped away. The Aboriginal people are slowly regaining ground after two centuries of unfair political and social treatment. How far have Aboriginal people come, and how far do they have to go, before they will truly be equal citizens? To answer this question, one must first look at how they were forced to the bottom of the ladder. Next, some of the recent changes that have occurred in government policy and social acceptance will be looked at. Finally, education and health care as faced by the Aboriginals in their lives daily will be discussed. History The problems facing Aboriginals today are many an... ...lian Nursing Journal. 11(9):37.

Per Clausewitz’s On War Essay

Per Clausewitz’s On War focal points on how victory can be achieved, reader see a keen interest in how to disarm the enemy using reciprocal and proportionate â€Å"efforts to his powers or resistance. † This implies that to win a war you might use all means, strength, and resources within your power to deliver the best strategy possible. Using â€Å"calculation of probabilities† victory can achieved by fully knowing what is at stake and how to attack at the right time. Being aware of the political agenda and reasoning behind a war allows for more awareness of political and military alliances in order to achieve victory in war. In addition, by understanding that there are tactics and strategy which must be used in war a victory can be acquired (website, Handel). To Clausewitz this means that â€Å"preparations for War† and the â€Å"War itself† must be seen as distinct entities. By preparing for the War you are acquiring all needed provisions and equipment, and comprehending the enemy and terrain in which the battles might be fought (Clausewitz Book 6). Sun too indicates that preparation for War is strongly required, and that without it practicality of strategy is lost. This would include any tactics to be used, calculations which can done, deriving rules or â€Å"even systems for the conduct of war†, and understanding that knowledge can be â€Å"converted into real power†. Clausewitz considers that â€Å"war is science when mere knowing; art, when doing. † This law of action must include strategy. This in turn â€Å"links together the series of acts which are to lead to the final decision† or finality of victory. Because these strategic elements are key to achieving victory, this author insists that the â€Å"use of engagements†¦. be classified into: moral, physical, mathematical, geographical, and statistical† aspects. This elements manifest within the process and act of War, and encompass the idea that strategic assembly of forces enables victory. Clausewitz indicates that the use of battle leads to the destruction of the enemy’s military, and that a great results is achieved by battle (KLINGER 79-89).

High school Essay

Education Does the perfect high school exist? Is there a school out there in which the students are all nice and responsible, every teacher enforces learning on the classroom, and the school system always makes wise decisions? No, probably not. At least, not any school I have ever heard of. There are multiple problems affecting high schools today, usually being either issues personally affecting an individual student, or issues affecting the whole school. Some examples of these problems may be: bullying, dropping out, not studying or doing homework, getting pregnant, not being taught to a full extent, financial issues, and etcetera. Like most problems, there is always a solution that we could benefit from. One of the most major issues hurting high schools today has to do with students being lazy. Teens go to school for the majority of their day, which is typically seven hours. Once they finally get home, it is safe to assume that the last thing on students’ minds is homework. They think â€Å"I have been at school allllll day! This is my time to relax; I do not want to do school work anymore! † So instead, they choose to sit down and watch Jersey Shore or log onto their Facebook accounts. In â€Å"The Liberal Arts in an Age of Info-Glut† by Todd Gitlin, he talks about comedy writer Larry Gelbart referring to media as â€Å"weapons of mass distraction. † If you think about it, this is pretty accurate. Televisions, the internet, etc are nothing but examples of distraction. Most teenagers are not responsible enough to think â€Å"I cannot watch TV right now, I have to study,† so they usually spend the rest of their night watching TV, causing a failing grade on the next day’s test. Teens in high school are not fully matured. Obviously, if they were mature, they would realize the importance of their grades as opposed the importance of who got in a fight on Jersey Shore. Due to this fact, I think we should â€Å"Let Teenagers Try Adulthood. † In this passage, Leon Botstein supports his idea to give teens a chance at adult life. As I have mentioned, teenagers are not mature enough to make decisions that will be good for their future. So why not let them graduate at the age of sixteen in order for them to understand the significance of being a responsible, mature person? Letting them graduate earlier could more than likely help students realize that it is time to grow up and take action for their lives. And maybe then, less time will be spent watching television, and more time will be spent on productive things†¦ mainly because they would not have a choice! Another major problem in high schools is the extremely high rate of students dropping out of school early. Teens drop out of school for multiple different reasons. Some leave school to escape bullying. There is always that one kid who is bullied so much, he just cannot stand it any longer. This is usually the kid in the back of the classroom, trying to stay hidden from everyone else, not doing assignments or paying attention. Scurrilous peers tend to make students want to stay at home forever, and never come back to school. Dropping out of school may be the victim’s way of getting away. Some students drop school simply because of boredom. They get tired of doing the same thing, every day. They feel as though they are not getting anything from it. In David S. Broder’s â€Å"A Model for High Schools,† he states that â€Å"Too many students are dropping out of high school, bored or dissatisfied with what it offers. † Throughout my three years of high school, I have seen numerous issues arise. Due to these many issues, personally, I do not like high school a bit. The problem most chronic would definitely have to be teen pregnancy. I remember during my freshman year, there were about twenty different young girls roaming the halls with a baby bump. During my sophomore year, there were twelve. The majority of the young women in high school that are getting pregnant end up dropping out and totally ignoring their education in order to raise their child. Those who do not drop out still have to miss tons of days due to their pregnancy and child birth†¦ which means, these students will get very far behind in their work, and will have to catch up on their own. Now, I am not saying that these girls should not raise their children, or that they do not have a reason to be absent frequently, I am simply saying this: Do not get pregnant in the first place! Education should always come first. Once they miss that month of school, it is going to be extremely difficult for them to catch up on their work. Because of this, most students will just give up and drop out. No one wants to be stupid, have a child at 16, and have to work at McDonald’s just to buy diapers and a box of Cheerios! Although there are still many issues arising in high schools all throughout America, these are more than likely the worst. Laziness and irresponsibility, dropping out, and getting pregnant can all cause students to end up with no education whatsoever, and lead them to a life of serving customers at the local Wal-Mart.

Child Labor and the British Industrial Revolution essays

Child Labor and the British Industrial Revolution essays The British Industrial Revolution (1770-1850) changed the social and economic life of Britain by establishing a completely new way of living and working. Prior to the Industrial Revolution, Britain was poor, though not without some economic surplus; relatively stagnant, though not completely static; and based on agriculture as its main economic activity (Deane 18). Because of the use of new food crops, such as the potato, and a decline in epidemic diseases, many of the major countries, including Britain, experienced tremendous population growth during this time. The population growth demanded the production of more goods, which soon brought about the development of factories. The technological advancements led to a new model of production and social relationships. The cottage workers were rapidly induced to long work hours in the large brick factories which resembled the stone poorhouses. Eventually, the cottage workers became unwilling to work in the factories which caused factory a nd mill owners to focus on abandoned and pauper children as their labor supply. These children were infants to 16 years old, averaging 4 feet 11 inches or less, and working 13 or 14 hours a day, six days a week (Spartacus). Child labor during this time became a significant topic for reformers, supporters, parents, children and the government. During the Industrial Revolution, there were many factory reformers who were against using child labor. John Fielden was born in Todmorden to Joshua Fielden, owner of a small textile business. From an early age, he had been taught to be concerned about the wellbeing and safety of employees of the company. In 1816, he and his brothers petitioned Parliament for factory legislation that protected child workers. Fielden founded a religious social reform group called the Todmorden Unitarian Society in 1822. He also advocated the introduction of a minimum wage and believed long work hours had a severe effect on worker...
