One more thing, for which service learning seems essential at college level, is that it enables students identify the roles, which they will need to play in society in future. When students engage in community activities, they become aware of their social roles and responsibilities in a very young stage of life. It is a fact that a society can

The Black Cat Essay Example for Free

The Black Cat Essay Short Story Analysis: The Black Cat The Black Cat by Edgar Alan Poe is a short story told in a first person narrative, from the point of view of an incarcerated murderer. There are several ways to interpret this story; the reader can also gain insight on the narrator’s state of mind. What I am going to talk about today is how the narrator uses a lot of symbolism and descriptive elements in his story, and in turn, how the reader will interpret the narrator as a person. A few characteristics that will be highlighted are death, psychosis/state of mind of the narrator, and alcoholism. The narrator admits an alcohol dependency right from the start. â€Å"One night, returning home , much intoxicated, from one of my haunts about town†¦Ã¢â‚¬ (2). This gives the reader the impression that it is in the narrator’s normal character to be under the influence. The narrator used alcohol as his reasoning for cutting the black cat’s eye out. He then drinks away his guilt and sins with alcohol, â€Å"I again plunged into excess, and soon drowned in wine all memory of the deed† (3). From these statements, the reader can assume that the narrator is an alcoholic and uses that to blur the reality of his decisions. Madness is defined as the state of being mentally ill or extremely foolish behavior. In this story it is apparent that the narrator could very well be mentally unstable. He immediately expressed his fondness for animals, he thought of animals as a â€Å"principal sources of pleasure† (2). He later gets pleasure from abusing one of his animals, the black cat, by cutting the cat’s eye out with a knife. All because he felt the cat was avoiding him. He later hangs the cat, and then constantly feels haunted by his acts. In a way, the narrator seems enticed by his evil actions. â€Å"Evil thoughts became my sole intimates-the darkest and most evil of thoughts† (5). The narrator’s last act of evil is the murder of his wife, when he hits her in the head with an axe. He then immediately thinks of ways to cover up the murder. He talks about cutting his wife up into pieces, but later decides that he will hide her body in the brick wall in the cellar of their home. From this the reader has gone from believing the narrator is just some troubled alcoholic, to believing the narrator is suffering some serious psychosis. There are many faces of death in this story. The first starts with the abuse of the black cat. The narrator comes home drunk and believes the cat is being disobedient so he cuts the cat’s eye out. Later, when his guilt builds up and he can no longer take it, the narrator hangs the cat. He becomes paranoid and believes the cat is haunting him from the grave. Although I thus readily accounted to my reason, if not altogether to my conscience, for the startling fact just detailed, it did not the less fail to make a deep impression upon my fancy†¦among the vile haunts which I now habitually frequented† (4). The next face of death is the cruel and unexpected murder of the narrator’s wife. It becomes apparent that the narrator has a disturbing fascination when carrying out the acts of murder. These actions tie into the narrator’s mental stability. It is one thing to have thoughts of harming one’s self or others, but it is another thing when those thoughts are acted upon. â€Å"My happiness was supreme! The guilt of my dark deed disturbed me but little† (6). From this the reader can assume that the narrator is a mentally unstable alcoholic murderer. The three main descriptive characteristics that I wanted to highlight about the narrator and the story of The Black Cat are alcoholism, psychosis, and death. With these three elements the reader can pass judgment on the narrator and create an overall opinion of him as a person. The reader can become first enticed by the story with the narrator talking about his love for animals and then later his cruelty towards them. Next the reader begins to wonder if the narrator is imagining these things, â€Å"Upon its head†¦sat the hideous beast whose craft had seduced me into murder, and whose informing voice had consigned me to the hangman† (7). Finally the reader can confidently asses their overall impression of the narrator. â€Å"Mad indeed would I be to expect it, in a case where my very senses reject their own evidence. But to-morrow I die and to-day I would unburden my soul† (1).

Sade animates Newtonian virtue :: French Literature Papers

Sade animates Newtonian virtue Sade integrated 18th century French materialism into his work at a such an elemental level that it is no exaggeration to say, as we will show here, that his pornography dramatises it directly. I will further argue that there is a strongly moral tone to his materialism : that characters are expected to practise what they preach, and to believe in their value system. The last part of my paper will look at how the opposing value system, Christianity, is satirised through the figure of Justine and that of the passive victims in general. Sade was an atheist, a Lockean sensationist and a materialist; he avidly read Diderot and d’Alembert’s Encyclopà ©die and the writings of the philosophes d’Holbach, Robinet, Condillac, La Mettrie and Buffon. He littered his works with references both tacit and explicit to the philosophes and passionately espoused what he saw as their cause. Their thinking was crucial to the construction of his own Å“uvre, and as he commented himself on his writing practice, â€Å"que veux-tu qu’on fasse sans livres ? Il faut en à ªtre entourà © pour travailler, sinon on ne peut faire que des contes de fà ©es, et je n’ai pas cet esprit-là  .† [what am I supposed to do without books ? You have to be surrounded with them to work, otherwise you can only do fairy-stories, and I’m not that way inclined]. I hope to show here just how close his own work was to the materialism of the philosophes. The Encyclopà ©die itself advocated a close expository relationship between science and literature. The article â€Å"Lettres† explains that: â€Å"†¦ les lettres et les sciences proprement dites, ont entr’elles l’enchainement, les liaisons, et les rapports les plus etroits; c’est dans l’Encyclopà ©die qu’il importe de le demontrer.† [literature and science are linked by the closest contact and relationship; it is up to the Encyclopà ©die to show that this is the case]. This assertion is of course based on the belief that science and literature are or should be about the same thing, that is to say, they are about life and nature. Life and nature, in the Encyclopà ©die, mean matter in all its various forms. Matter was defined by the Encyclopà ©die as a â€Å"substance à ©tendue, solide, divisible, mobile et passible, le premier principe de

Discussing conflict theory in sport Essay

Americas favorite pastime is sport. Millions and millions of dollars have been spent publicizing sport, and on the same token millions and millions of dollars have also been spent watching it. Children grow up idolizing sport. Parents have been obsessed with sport. In Texas football is valued very high- from high school football to the NFL there is an obsession with the sport. The Dark side of the Game discusses a conflict theory perspective on the high stakes that surround the players in the NFL. Fame and fortune can be short lived for some players who are pursuing that American dream, and may be forced into retirement with their bodies left mangled and used up. The NFL is seen as pristine with cutting edge competition. The fact beyond the fiction is that the common person in society looks at sport with rose- colored glasses. It is no lie that some athletes do live out the life that they have dreamed of, but many also suffer by compromising their beliefs and morals. The Dark Side of the Game starts with the beginning aspects of playing in the NFL. The Combines,or the process by which the players are medically examined and given an intelligence test is the gateway to the NFL. Your health is a determining factor in whether your stock in the upcoming draft will drop. Next comes training camp. Most fans look forward to training camp; it is the time to get pumped up about the upcoming football season and watch your favorite teams get prepared. To an NFL player training camp can be a month of hot torture. Days start at seven in the morning and can end at nine at night, leaving players weak and tired and with a loss of appetite. Training camp is especially hard on the rookies. They are not used to the difference between college football and the NFL because they are no longer in the spotlight. Training camp also takes a physical and mental toll on the athletes mind and bodies. Repeating the schedule day after day physically breaks down the body. The injuries can start to build up and take a toll on the body. Being deprived from family and friends takes a mental toll on the body as well.  Some players might even try to get out of training camp, but the two things that might get you out for a day or two would be- death or having a baby. When the season begins playing with pain is usually a norm. Players always know the difference between pain and discomfort. Discomfort is seen as a constant state for a player, something like a bruised toe. Pain, on the other hand, is â€Å"the physical damage that is so extreme that the jolting messages sent from the injured area to the brain are just too much to be ignored, even during a game when your entire focus is on doing your job and winning.†(Green). While no one knows exactly how much pain tolerance one man has, it is still true that players have played with pain at some time or another. When the end of their career finally rolls around most players don’t just retire, they are told they are a financial burden to justify anymore. It is hard for them to just walk away from the game they call their career. They are spoiled with special treatment, attention, fame and fortune. When the party is over know one wants to leave. After reading Tim Greens book I thought he generally took a very negative approach to describing the NFL. Although I could never know what the NFL is like, it seems like it should be more affirmative than that. He started out describing training camp as a living hell, all the way to the two deaths that a football player dies with- the end of his career being the first. In my opinion, I believe that there are probably several players who did not get such a negative outlook on it. I believe it is probably the expectations that you set for the game itself. Everyone expects a red carpet for a professional athlete because of the money and fame they receive for doing something they love. Being a professional athlete is probably an emotional struggle for players between expectations and reality. The truth is that their choice is to play, and not one of them would have it any other way. The book I read is a conflict theorist perspective. Green takes all of the negative aspects of life in the NFL and explains that the NFL does not serve as a function, but more or less a struggle. He does not believe that all functions in the NFL are good or productive, therefore he doesn’t believe that the NFL contributes to overall well being to the players. There are several examples of exploitation of players, such as the media and the broadcast booth. Green also goes on to say that the NFL meets the goals of the powerful by describing such things like the salary cap or the â€Å"uniform police†. Overall this book covers several negative aspects of football that the average fan would not think twice about. Millions of little boys dream about being a professional athlete, and a small percentage will become one. Despite the conflicts represented in this book, I believe that for a majority of people, life in the NFL is dream that few will ever know. Bibliography Green, Tim. The Dark Side Of The Game.

Importance of Human Capital in Economicdevelopment

The modern economists are of the view that natural resources i†¦ e forest minerals, climate, water power etc. play in important role in the economic development of an country. A country which has abundant natural resources is in position to development more rapidly than a country which is deficient in such resources. They here how ere emphasize that the presence of abundant resources is not a sufficient condition of economic growth.Physical factures they say are passive factors of economic growth. They are to be combined with human resources of a country who are active facture of economic development. Human resources of a country are the size of population rate of growth of population urban rural distribution of people and quality of population. The quality of population as measured by health standards educational levels and technology is vitally important in influencing a nation's cultural and economic progress.A country which has developed the skills and knowledge of its peopl e can exploit natural resources, build social economic and political organizations and can carry forward national development. The less developed countries of the world are now making investment in human persons for increasing their skills abilities ideals health on the job training programmers. These productive investments have a strong bearing upon increasing human capabilities which is called human capital. 2. What is human capital? Its Role in Economic Development?Human capital can be described as the skills training and health acquired through on the job training and education Michael Pakistan Park in defines it as: †The skill and knowledge of human beings. † It is also defined as: â€Å"The endowment of abilities to produce that exists in each human being. It can be increased through formal education, on the job training and improved health and psychological well being. To be more precise. If the people of a country are well educated, well nourished, skilled and h ealthy, they are said to have more human capital. 3. Human capital formation: Human capital formation as described by Professor Harrison as †the process of acquiring and increasing the number of person who have the skills, education and experience which are critical for the economic and political development of a country. †Human capital formation is the act of increasing the productive qualities of labor force by providing more education and by increasing skills, health and notarization level. According T. W. Schultz, there are five ways of developing human capital. i) Provision of health facilities which affect the life expectancy, strength, vigor and vitality of the people. (ii) Provision of on the job training which enhances the skill of labor force. (iii) Arranging education at the primary, secondary and higher levels. (iv) Study and extension programmer for the adults. (v) Provision of adequate migration facilities to families to adjust to changing job opportunities . 4. Importance of human capital: Human capital is the fundamental source of economic growth. It is a source of both increased productivity and technological advance.In fact the major difference between the developed and developing countries is the rate of progress in human capital. The under developed countries need human capital to staff new and expanding government services to introduce new system of land use and new methods of agriculture, to develop new means of communication to carry forward industrialization and to build the education system. Prof. Galbraith is right in saying that †we now get larger part of economic growth from investment in men and improvements brought about by improved men. ‘ 5. Problems of human capital formation in LDC's: The main problems of human capital formation in less developed countries (LDC's) including Pakistan in brief are as under. (i) Faster increase in population: The population of almost all developing countries of world includi ng Pakistan is increasing faster than rate of accumulation of human capital. As a result thereof, these countries are not making the satisfactory use sector expenditure on education is about 2. 5% of GDP for the last over five years. ii) Defective pattern of investment in education: In the developing countries of the world, the governments are giving priority to primary education for increasing literacy rate.Secondary education which provides critical skills needed for economic developed remains neglected. Another problem related to investment in education is that in the public and private sectors there is a mushroom growth of universities without trying to improve their standard of education. There are also mass failures at primary, secondary & higher levels of education resulting in wastage of the scarce resources of the countries. iii) More stress on the provision of building and equipments: Another major problem of investment in human capital in developing countries of the world is the politicians and administrator lay more stress on the construction of buildings and provision of equipments than on the provision of qualified staff. It has been observed that foreign qualified teachers and doctors are appointed in rural areas where there is little usefulness of them. (iv) Shortage of health and nutrition facilities: In the less developed countries of the world there is shortage of trained nurses qualified doctors medical equipment, medicines etc.The less availability of health facilities pose threat to the millions of the people living there. The people are faced with unsatisfactory sanitary conditions, polluted water, high fertility and death rates urban slums, illiteracy etc. All these deficiencies affect the health of the people reduce their life expectancy. (v) No facilities of on the job training: On the job training or in service training is very essential for improving or acquiring of new skills to the persons employed in various importance is given o n the job training for the employees.The result is that the efficiency and knowledge of the workers remains technicians etc. is therefore of utmost importance for the efficient use of human resources. (vi) Study programme for adults: Study programme for adults can also be introduced for improving literacy rate. Programme for adults was introduced in many under developed countries of the world including Pakistan for providing basic education. increasing skills farmers and small industrialists. The scheme has miserably failed as no interest was shown by the adults in getting such training. (vii) Half earted measures for promotion of employment: In most of the world the ratio of unemployed or under employed persons is very large. For increasing employment and reducing under employment proper investment in human capital is required which is visibly lacking in LDC's. The govt. of Pakistan has taken a number of steps for increasing employment opportunities in the country such as establish ment of SME Bank for the promotion of self employment at the grass root level, encouraging domestic and foreign investment for increasing employment opening of technical and vocational training centers etc. tc. (viii)No manpower planning: Due to non availability of reliable data there is little manpower planning in less developed countries of the world including of course Pakistan. As a result thereof, there is no matching of demand and supply of different types of skills. The result is that large number of skilled and highly qualified persons remain underemployed. The frustration and discontentment among the unemployed or underemployed graduate and post graduates result in brain drain from the country. It is a huge loss to resources of developing countries. ix) Neglect of agriculture education: In LDC's where agriculture is the major sector of the economy. , very little attention is paid for educating the farmers to the use of modern agricultural practices. Unless the farmers are p rovided agricultural education and training on the fields, they will not be able to raise the agricultural the outlook of the farmers. 6. IMPORTANCE OF HUMAN CAPITAL ON SOCIAL AND ECONOMIC DEVELOPMENTP: In today's world production of goods and services on large scale are knowledge intensive.Knowledge can be imported and increased by making investment in education and provision of better health services to man. which is called investment in Man' or Human Capital Formation. The modern economists are of the view that a dollar invested on education bring a greater increase in national income than a dollar spent on dams, roads, bridges or other tangible capital goods. In the words of Professor, Galbraith, we now get the larger part of our industrial growth not from more capital investment but from investment in men and improvement brought about by improved men. ‘ The importance of human capital on economic and social development is now disused in brief. (i) Human Capital as a creat ive and productive resource: In all the developing countries of the world physical capital is invested in the construction of roads, dams, light and heavy industries, schools, hospitals etc. For proper investment and operation of these projects at low cost, you need the services of technicians, engineers, administrators, etc. If priority is not given to human investment and adequate resources are not invested in a man, the physical capital cannot be properly used.It will remain unutilized, underutilized, and misutilized. (ii) Rise in Marginal Efficiency of Capital: Human capital is now regarded as the most potent source of economic growth. It is a way of increasing output by increasing not the quantity of lab our but its quality. Investment in human capital improves the skills of work force and helps in raising marginal efficiency of capital. (iii) Utilization of foreign loans: The advanced countries of the world are assisting the developing countries by providing them grants, loans food supplies and technical expertise etc.The better education, the provision of knowledge, skills, expertise helps in proper utilization of foreign loans. (iv) Utilization of surplus manpower: The underdeveloped countries in general have abundance unskilled and untrained manpower. There is widespread under-employment and disguised unemployment in the urban and rural areas. The investment in right type of education, training, skill, health and nutrition sound manpower planning, on the job training programs etc. can go a long way in absorbing the surplus labor force and developing job opportunities. v) Effect on Health and Nutrition: Human capital formation also calls for investment in health and nutrition. If is a common knowledge that poverty, ill health, illiteracy and low productivity constitutes a vicious circle of poverty. If proper investment is made in health, nutrition drinking water etc. there will be improvement in the health of the people. There will be a desire of the p eople to work and increase production. The improvement in health status of the people thus helps in reducing population growth raising income and higher economic growth in the country. (vi) Social Change:Investment in human capital makes a positive contribution towards improving and brining fast changes in the economic and social life of the people of developing countries. Investment in human capital raises the general living standard of the people in less developed countries, it improves the quality of population i. e.. health and nutrition, literacy, skill, knowledge, desire to work. The surplus manpower is better mobilized and utilized for economic development. There is also a change in social climate of the people. The rate of social mobility increases. There is increased urbanization and industrialization.

Development of a Web Based Recruitment Process System for the Human Resource of an Organization Essays Development of a Web Based Recruitment Process System for the Human Resource of an Organization Paper Development of a Web Based Recruitment Process System for the Human Resource of an Organization Paper DEVELOPMENT OF A WEB BASED RECRUITMENT PROCESS SYSTEM FOR THE HUMAN RESOURCE OF AN ORGANIZATION CASE STUDY:UGANDA VIRUS RESEARCH INSTITUTE SUBMITED BY: NAMBALE JOHN BOSCO REG NO: 2007-03-IT-042 LECTURER: MR OTHIENO JOSEPH 1. 1. Introduction For an organization to run successfully and efficiently its very important that it has efficient workers and to use its resources very well especially human resources. So one of the important goals of an organization is to recruit right people for the right job. So there should be a proper recruiting process management system so that all the activities and selection procedure can be carried out effectively without losing its transparency. A web based recruitment system will be of great help in carrying out recruitment operations and with this very objective in mind this web based recruitment system will be made. In this web based recruitment system it will manage all such activities (like storing applicants data, scheduling interviews, retrieval of recorded data and easy application) and that will save time, manpower and the biggest advantage of being it web based. This web based system will provide better prospective for the enhancement of organization regarding to quality and transparency. 1. 2. Background of the case study The Uganda Virus Research Institute (UVRI), located in Entebbe, Uganda, was established in 1936 as the Yellow Fever Research Institute by the Rockefeller Foundation. In 1950, after gaining regional recognition it was renamed the East African Virus Research Institute (EAVRI). After the collapse of the East African Community in 1977, it became a Uganda government public health research institution and was renamed the Uganda Virus Research Institute. The government of Uganda now administers and funds the institute through the Uganda National Health Research Organization (UNHRO) which is an umbrella research body with in the Uganda Ministry of Health. The mission of the institute is to carry out scientific research concerning communicable diseases, especially viral diseases of public health importance and to advise the government on strategies for control and prevention. The institute also plays a large role in coordinating and administering virology related clinical trials within the county. Most recently the institute has been involved in human HIV vaccine clinical trials. The HIV/AIDS Reference and Quality Assurance Laboratory (HRL), which is part of the institute plays an important role in making public policy recommendations to the Uganda National Drug Authority on the access and usage of new drugs and medicaltechnologies. 1. 3. Problem Statement The current recruitment processes are primarily manual and paper based. These processes are labor intensive, costly and unfriendly from the applicant and managerial point of view. It is worth notifying that with the increasing number of applicants at the institute and with this current recruitment processes which are primarily manual and paper based are no longer efficient. It is the intention to replace these with a system that will allow direct job applications on-line and improve this situation. 1. 4.

Free Essays on Social Learning

Social Process (Social Learning Theory) Most human behaviors are learned through the process of observing others forms of how behaviors are performed and perceived, this in the future serves as a guide for our own actions. This Social Learning Theory, also known as social process, has thoroughly been applied to many of our adapted traits. Aggression and psychological disorders have been extensively rooted to this theory in studies in such areas. Public policies aimed at social process help reduce the involvement with deviant peers, reducing exposure to violence in the home, community, and the media. It is very important to notice the policy implications used to aid these problems rooted at the social learning process such as, intervention/ preventions, schooling, and diverse types of peer modeling. Observational learning begins with your family and how you are brought up around them and your peers. The family is an extremely crucial key to a child’s development and a healthy upbringing. All of the people who surround you during your time seem to influence your behavior and your perception of certain behaviors. This is where all of the learning begins and this is where much focus on strong family needs to be applied. Agencies such as Outreach offer a range of prevention and intervention programs designed to help prevent bumps in the road such as school failure, juvenile delinquency and substance abuse among youth. Preschool education and early family support have, in randomized trials, been shown to have positive health outcomes in terms of reduced child abuse, neglect and injury, drug misuse, and teenage pregnancy.

You can then enter a position and industry, and Resume Assistant will pull information from millions of people’s public profiles on LinkedIn that match that position and industry. You can then use the examples to inspire your own resume content and â€Å"make sure you stand out from the crowd.† LinkedIn claims, â€Å"Ditch the one-size-fits-all resume†¦ Resume Assistant provides the top skills other professionals in your desired role and industry have, as well as job requirements from real job postings. You can then think about how your applicable skills can be transferable for the role you want, then tailor your resume to fit that role.† All this sounds too good to be true. It requires users to think hard on their own, resist the temptation of copying and pasting, and basically write their own resume. I’m not sure it will make resume writing easier for anyone who does it right. Perhaps it will provide some valuable research, but beyond that, I’m not clear on its usefulness. Is Resume Assistant Evil? One of the most vocal opponents of Resume Assistant is Donna Serdula, who claims LinkedIn is committing â€Å"Profile Plagiarism.† I don’t know about that. Certainly a diligent person can do their own search for people with their position title, and model their profile or resume off someone else’s. My understanding is that what Resume Assistant does is crunch numbers so you get a more accurate picture of what skills are the most important to include in your profile. It seems to me that Resume Assistant is streamlining a process, not committing plagiarism. What is disturbing to me, and to Donna, is that LinkedIn and Microsoft have failed to inform LinkedIn members that Resume Assistant will pull information from your profile unless you opt out. Even if all the information is from your public profile and your name is not attached to it, making people’s profiles automatically available for scanning is a bit sneaky, if you ask me. Here’s how to opt out of the Resume Assistant so your information is kept out of people’s hands who are using the program. Note that if your profile is public, resourceful folks could still find your profile and â€Å"flatter† you with imitation. Click on your profile image thumbnail in the upper right corner. From the drop-down menu, select Settings Privacy. On the Privacy tab, scroll down to Data privacy and advertising, and under Microsoft Word, flip the switch to No. Or,  follow this link. I’m choosing for now to keep my information public and available to Resume Assistant. At least I know I’ll be contributing quality material to those who need it. How Does Resume Assistant Really Work? Unfortunately, at this time, I am not able to tell you exactly how Resume Assistant works. I had to go to Microsoft’s article, Write your best resume in Word with help from LinkedIn in Resume Assistant, to figure out that it’s supposed to show up under my Review tab in Microsoft Word. Microsoft provides a bit of practical information, including how to opt out of having your information used. None of the information I could find on LinkedIn actually explains how to start using it. I’m hoping that will change soon. One big question that remains for me is about the quality of information that shows up on Resume Assistant. Believe me, I’ll be testing it out as soon as that option appears in my version of Word! I’m concerned that low-quality information could steer people in the wrong direction as they’re writing their resumes. There might be something I’m not aware of, but I would not want to take just anyone’s profile in my industry and model my resume after it. I can’t emphasize enough that someone else’s achievements are samples only! If you imitate their achievements exactly, you are either committing plagiarism or you have some work to do in distinguishing yourself in your career. Will You Use Microsoft’s Resume Assistant? While Resume Assistant seems like a marketing ploy to get people to subscribe to Office 365, for me, the jury is still out on whether might actually have true value. I hope you’ll test it out if it’s available to you and you’re looking for ways to improve your resume. Perhaps it will be the resume writers’ new favorite tool! I look forward to sharing more as the opportunity to use Resume Assistant becomes a reality.

Singer and Regan's Approaches to Animal Liberation Assignment

Singer and Regan's Approaches to Animal Liberation - Assignment Example Singer makes use of the rights language as shorthand for how we might want to treat other people in his arguments. Instead, singer argues that, when we put the consequences of an act into consideration when judging acts, it will be in order to put the interest of animals, primarily their interested to prevent any suffering, to have the same consideration to the same interest put on humans. That is to say, where one individual suffering either human or non-human is considered equal to that of any other, there is no reason that can justify one to put more weight to one of them. On the other hand, Regan’s approaches concerning animal rights are not driven by the ultimate consequences of the actions. Regan firmly holds the belief that animals are what he is referring as the â€Å"subjects of a life†, for that reason who has the moral rights, and for that reason, their moral rights should not be ignored as such. He argues that animals do have one moral right and even a legal one, and they should not be as anyone’s property. Singers approach of utilitarian means that he is judging the "rightest" of any act by the consequences it attracts. Specifically by the extent that the act tries to bring satisfaction to the things that are affected, maximizing on the pleasures developed and pain minimization. Other forms of utilitarianism do exist such as rule utilitarianism. This rule tries to judge the rightness of any action basing on the usual consequences of whichever the moral rule the act has been practiced. According to Singer’s grounds, he clearly states that there exists no moral ground when an individual fails to give equal consideration of rights that hang to the interests of both non-humans and humans.  

Media and Politics. Picking a local topic, national, and world topic Essay

Media and Politics. Picking a local topic, national, and world topic. Present topic - Essay Example This is because one source will have either some strength or weaknesses, therefore advantaging or disadvantaging the rival source, resulting in the differences. The media, for being such an influential part of society, requires regulations and ethics to govern what qualifies to broadcast or not, for instance in the case of politics, it is important for sources to remain neutral and not influence society in any way. Introduction The general media is a valuable source of information and a powerful medium of information that largely influences the understanding of daily events and occurrences of the people who access its releases. As a watchdog, the media has the potential to either be faithful or not, as it enjoys unlimited freedom in choosing and deciding what is worth publicizing or not, and what perception to create around a certain event or occurrence. The media is a wide fraternity of society comprising of numerous sources at different levels and has similarities, differences, str engths, weaknesses, and much influence on all aspects of society. This essay will conduct an analysis of media sources at three levels; local, national, and international, and bring out the mentioned qualities by comparing the uniqueness of two different media sources at each level in their mode of relaying similar political events. Local media level Local media coverage defines broadcasting of information concerned with a specific context such as a state, whose news would not be of much relevance to other states or to the larger national and international communities. In this case, this study will compare and contrast the relay of news concerning the 2012 accusation of (former) 18th Lieutenant Governor of Florida, Jennifer Carroll, of having a lesbian relationship with an aide in which we shall feature the Miami Herald and Sun-Sentinel as our news sources. The Sun-Sentinel The article with Carroll’s story as appearing on this media source on 12 July 2012 had the headline â⠂¬Å"Sex scandal becomes the talk of Florida’s capital.† The story is introduced with catchy words such as â€Å"titillating sex scandal† and goes on to describe Carroll as one who does not feature much in the news headlines but is this time in the limelight due to criminal charges. However, after this, there is not much mention of her accusations. Rather, the stories focus on one Carletha Cole who is Carroll’s former spokesperson and who is accused of conducting illegal recording. The story does not seem to directly attack Carroll, and all her accusations arise from second parties such as Cole’s attorney bringing up the sexual accusations, but not the source itself. The source does not reveal what the results of a polygraph test carried out on Cole were. At the conclusion of the story, there is much positive information about Carroll, such as the women representatives describing her as a role model. She is also linked to Christianity, and her histor y is depicted as never tainted before (Haughney and Bureau 1). The Miami Herald The Miami Herald’s headline of the topic is â€Å"Is Lt. Gov. Jennifer Carroll’s Former aide seeking vengeance or injustice?† In this source, Cole’s attorney introduces the sexual accusations against Carroll, this after we learn that Cole is facing criminal charges of illegally taping audio around the Florida State offices. In this article, they

The First Satellite and its Original Purpose Assignment

The First Satellite and its Original Purpose - Assignment Example Active margin exists in the leading edge of the continent, where it crashes into an oceanic plate. Passive margin, on the other hand, refers to margins that exist in the other remaining coastlines, without any collision and subduction activities taking place. Walking onto the beach of each margin differs in that the active beach has the formation of different geographical features because if different activities such as earthquakes, whereas the passive beach remains relatively flat. A deep ocean trench is a depression in the deep ocean floor in the shape of an arc, while submarine canyon is a cutting into the continental shelf and slope making an end into the deep sea fan. Ocean trenches, usually, go deeper into the ocean than a submarine canyon, with submarines hiding in both. The four sources of ocean sediments are terrigenous, biogenous, indigestible, and exogenous sediments. Terrigenous sediments are sediments formed on land then washed into the ocean by the action of rivers. Biogenous sediments refer to sediments resulting from the discarded parts of living organisms both on land and in the sea, with their entry into the ocean being similar to that of terrigenous sediments. Indigestible sediments refer to shells, shell pieces, and fecal pellets as particles or other forms of sediment wrapped in the waste products of sediment-eating bottom dwellers in the ocean base. Finally, exogenous sediments are the particles from space, making a small percentage of the ocean sediments. Exogenous sediments get to the ocean floor by running waters into the ocean such as rivers after the sediments are deposited on the earth’s surface. Some of the sediments also fall directly into the oceans from space. The two natural resources are Udachnaya pipe located in Russia just outside the Arctic Circle. It has diamond deposits extracted through mining and used by the human as an economic resource.  

The OJ Simpson Trial Essay Example | Topics and Well Written Essays - 1250 words

The OJ Simpson Trial - Essay Example Simpson â€Å"not guilty†. The Evidence The DNA evidence against O.J. Simpson was the most powerful evidence presented against him. The prosecution presented DNA samples on the alleged blood drops and footprints of Simpson that was positive for DNA match. The blood drops was said to be collected at Nicole Brown’s home, in Simpson’s car and his home. Another important evidence was the bloody glove found at Simpson’s home that tested positive for the DNA of Simpson and the victims Brown and Goldman. Although a surprising amount of DNA evidence was produced by the prosecution, as author John M. Butler believed â€Å"DNA evidence is not always understood and can be quite complex to explain to the general public†.1 The defense team took this complexity as an opportunity to debase prosecution’s DNA evidence and attacked on the validity of the collection and the preservation of the evidence. They argued that the evidence was mishandled and violated the â€Å"chain of custody† as provided in the Rules of Evidence. A systematic argument was created by the defense panel in invalidating the evidence, including the possible contamination of the blood drops collected, and the alleged planting of evidence by police officers on the samples found in Simpson’s car, footprints, and the bloody glove that was found in the murder scene by Detective Mark Fuhrman. The handling of the samples openly, created the â€Å"reasonable doub†t of possible contamination in the DNA testing. Although the DNA test resulted positive, the doubt of its validity gave more credibility to the jury. But perhaps, the most positive result that failed to convict Simpson of guilt beyond reasonable doubt was the presentation of the bloody glove as object evidence. The defense team demonstrated their argument by asking Simpson to fit the questioned glove. As demonstrated, the glove was small and could not fit Simpson’s athletic hands, which lead Johnnie Cochran, Simpson’s lawyer to say the infamous line â€Å"if the glove doesn’t fit, you must acquit†. Another prosecution weakness was the presentation of Detective Mark Fuhrman as a witness. The defense team took note of Fuhrman’s history of racism, by attacking his character based on beating up suspects and prior statements recorded using the word â€Å"nigger† repeatedly in an interview made by a screenwriter in 1986.2 The prosecution attempted to present character evidence against Simpson that was in general rule, not allowed by the Rules of Evidence. But Judge Ito accepted the character evidence presented by applying the same on the angle of a possible motive by Simpson to allegedly perform the murders. Arrest records were found indicating that Simpson was charged with domestic violence. A picture of the beaten and bruised ex-wife Brown was presented in court. But the images were not enough to convict Simpson and remove the doubt that the planted evidence has created. THE JURY The Sixth Amendment of the US Constitution provides for the right to elect a trial by jury. Unlike other judicial procedure in most part of the world that follows an inquisitorial system (where a judge makes a decision based on witnesses and evidence in an investigative form), a trial by jury is an adversarial process. Janet Coterril explained that an â€Å"adversarial trial process attempt to persuade the jury that one constructed version of reality is more plausible than the other†, giving more focus on â€Å"

Change Model Research Paper Example | Topics and Well Written Essays - 500 words

Change Model - Research Paper Example The model requires that the implementation plan should begin by encouraging of the nursing staff to identify the practice questions that are either triggered through identification of a new knowledge or problem. In this plan, the model would that practice questions relating to the response to medical adherence to newly diagnosed young male with coronary heart disease be identified first. This will be essential in allocation of supporting resources to the top-most priorities. The next step that the model requires in implementation plan is formation of a team to develop, evaluate and implement the practice change. This team should be made up of stakeholders in the practice change; the team may include unit managers, interdisciplinary colleagues, and the staff nurses that identified the practice questions. Therefore, a team should be formed comprising of the aforementioned persons in order to effectively implement the plan (Reed and Lawrence, 2008). The model further requires that the team that has been formed should select, critique, review, and synthesize all the available research evidence relating to the implementation plan (Titler et al, 2001). In an event that the evidence is not sufficient, the team can make recommendations using lower evidence levels or by conducting additional research. If the evidence is adequate, then the practice can be initiated. After ascertaining this aspect, the team involved in this implementation plan should pilot the practice change in a bid to determine the effectiveness and feasibility. If the results of the pilot projects are positive, the team should facilitate integration and roll-out of the practice through continuous monitoring of outcomes, education, and leadership support. Thereafter, the Iowa Model requires that the reports of the projects to be shared outside and within the organization through publications and presentations. The model emphasizes on this step as it is important in supporting the

International economics Essay Example | Topics and Well Written Essays - 2500 words

International economics - Essay Example However, the entire practice of import and export has been subjected to multiple trade policies and regulations to maintain international harmony and restrain a control over international trade practices. Over time and under specific conditions, the structuring of the trade practices has also evolved (Davis, 1995). Considering all these aspects, this discussion focuses on analysing the type of commodities imported and exported by Singapore between the periods of 2010 to 2013 to find their alignment with the established international trade practices. The discussion emphasizes multiple crucial facts regarding the international trade practice carried out by Singapore in developing a better competitive advantage. In addition to all these, considerable amount of focus will also be laid on the tariff plans that are being imposed on the goods being imported in Singapore. Supportive facts such as worth of Singapore currency internationally will also be provided in the discussion. A considerable amount of focus needs to be provided on the fact that majority of the goods that are being imported in Singapore are tax-free excluding some of the liquor based commodities. Moreover, by analysing the trading figures between the periods of 2010 to 2013, it can be identified that the trading pattern appears to have dropped to a certain extent during the period of 2013. The graph projected below will help to understand this difference in an appropriate manner. The above mentioned two graphs clearly stated about the import and the export patterns of Singapore at the present currency rate i.e. Singapore $1~ $0.80 USD. Respectively, it can be stated that the export rate within the four fiscal years have elevated, which has apparently brought in huge loads of foreign exchange in comparison to that of the imported rates regardless of the fact that the import rates have also elevated much. However, if the evaluation is conducted depending on the types of import and

Think Tanks in the United States Essay Example for Free

Think Tanks in the United States Essay A think tank (also known as a policy center) is a non-profit research institution that conducts studies on public policy (Columbia University Libraries, n. pag.). Aside from public policy analysis, a think tank also engages in developing solutions for national or commercial problems (Rohrer, n. pag.). Although there are some think tanks that are strictly nonpartisan (their research on public policy issues are not affected by political outcomes), think tanks are generally regarded as organizations that provide intellectual support to political parties and or politicians. Hence, a think tank is considered as an important part of the American political scene (Columbia University Libraries, n. pag.). However, think tanks affect American foreign policy and economic development abroad by coming up with ethnocentric and xenophobic perspectives. In some cases, American think tanks create unsustainable, violent and even genocidal policies, majority of which the US government imposes on Third World countries. Worse, the civilian nature of these organizations allows them to escape accountability for their detrimental ideas (Hayes, 3).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In the article A Litany of Horrors: America’s University of Imperialism (2008), Chalmers Johnson wrote that the RAND Corporation, one of the oldest existing think tanks in the US, was â€Å"the premier think tank for the US’ role as hegemon of the Western world (Johnson, n. pag.). To support his argument, Johnson detailed the history of RAND’s active participation in US military intervention since it was founded after World War II. During the Cold War, RAND perpetuated the â€Å"arms race† between the US and the Soviet Union by urging the latter to create huge demands for weapons such as atomic bombs, nuclear submarines, intercontinental ballistic missiles and long-range bombers. In the 1960s and the 1970s, RAND’s anti-Marxist rhetoric heavily influenced the US to get involved in the Vietnam War and to establish puppet governments in Third World countries that included the Philippines, Thailand, Chile and Taiwan (Johnson, n. pag.).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   RAND was also heavily involved in the Iraq War in 2002. During 9/11, former Defense Secretary Frank Carlucci was the co-chair of the RAND Center for Middle East Public Policy Advisory Board and was also a member of the RAND Board of Trustees. However, he was likewise the chairman of the Carlyle Group, a defense contractor with strong connections to the Saudi Royal Family and the Bin Laden clan. Other key players in the Iraq War that held important positions in the RAND Corporation were Paul Wolfowitz, Condoleeza Rice and Donald Rumsfeld (Here in Reality, n. pag.).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Aside from the RAND Corporation, other American think tanks that were also occupied with the promotion of American foreign policy and economic development abroad were the National Institute for Public Policy (NIPP) and the Project for a New American Century (PNAC). Akin to RAND, the administration of the NIPP and the PNAC are both composed of unilateralist ideologues, most of which are former executives, consultants or major shareholders of the country’s biggest defense contractors. Some of the individuals who were connected to these think tanks went on to become government officials. Hence, it should no longer come as a surprise if US military intervention has increased in the previous decades (Ciarrocca Hartung, n. pag.).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The NIPP has strong ties with the nuclear weapons industry. Most of the members of its advisory board were formerly connected with the arms and nuclear divisions of major defense contractors. Kathleen Bailey, for instance, worked as an analyst for the Lawrence Livermore nuclear weapons laboratory for six years. Robert Barker, meanwhile, worked for the weapons laboratory of Lawrence Livermore for 30 years. Charles Kupperman was Lockheed Martin’s vice president for its national missile defense programs (Ciarrocca Hartung, n. pag.).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The leadership of the PNAC is made up of William Kristol (editor of the Weekly Standard), Robert Kagan (senior associate at the Carnegie Endowment for International Peace, contributing editor at the Weekly Standard and columnist for the Washington Post) and Bruce Jackson (a longtime Lockheed Martin executive). Founded in 1997, PNAC’s principles were based on â€Å"the Reagan administration’s success (in ending the Cold War)† and called for the revival of â€Å"a military that is strong and ready to meet both present and future challenges† (Ciarrocca Hartung, n. pag.). It must be noted that the founding document of PNAC was signed by major players in the Bush national security team, such as Paul Wolfowitz, Dick Cheney and Donald Rumsfeld. Furthermore, PNAC’s deputy director Thomas Donnelly was hired by Lockheed Martin in 2003 (Ciarrocca Hartung, n. pag.).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Given the background of RAND, PNAC and NIPP, it is very clear that there is a conflict between the objectives of think tanks and American foreign policy (which focused mainly on promoting American values abroad). Most of the think tanks that are affiliated with the US government are also connected with companies that benefit financially from war. It is therefore just a matter of common logic to assume that think tanks like RAND, PNAC and NIPP will advise the US government to wage war on other countries (no matter how flimsy the justification is) simply because the defense contractors that they are connected with will earn immensely from doing so.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Furthermore, there are some US politicians who are likewise affiliated with organizations that profit from war. Former President George Bush, Sr., for instance, is a former Senior Advisor in the Carlyle Group. Former Secretary of State and Secretary of Treasury James Baker, meanwhile, was former Carlyle Senior Counselor. Carlyle Managing Director Richard Darman also happens to be the White House Budget Advisor (Here in Reality, n. pag.). It is very obvious that their affiliation to Carlyle makes them view war as an avenue for profit, and not as an atrocity that claims countless innocent lives.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   While think tanks are excellent sources of information and ideas, conflict of interest arises when these institutions affect government policy. Think tanks doing business and making money while advising the US government at the same time should be considered as a grave cause of concern. Indeed, what will think tanks do when private business clash with public policy? What will be their stand when the very same government official that they supported is criticized for applying the ideas that they have formulated?

Mummy Case of Paankhenamun Essay -- Archeology Egypt Analysis Essays

Mummy Case of Paankhenamun Works Cited Not Included The work I chose to analyze was from a wall fragment from the tomb of Ameneemhet and wife Hemet called Mummy Case of Paankhenamun, found in the Art Institute of Chicago. The case of the Mummy Paankhenamun is one of the most exquisite pieces of art produced by the Egyptian people during the time before Christ. This coffin belonged to a man named Paankhenamun, which translates to â€Å"He Lives for Amun† (Hornblower & Spawforth 74). Paankhenamun was the doorkeeper of the temple of the god Amun, a position he inherited from his father.   Ã‚  Ã‚  Ã‚  Ã‚   Interestingly, X-rays reveal that the mummy case of Paankhenamun does in fact contain a mummy inside dating back to the years of c. 945 – 715 B.C. The practice of mummification was the Egyptian people’s way of preserving the spirits of the Gods/Goddesses and royalty. The idea was that when these beings came back to life, they would be preserved and well prepared for their next lives. By the time of the New Kingdom, the Egyptians already had developed techniques of mummification, which were done under a priest’s supervision (Stokstad 114), and since Paankhenamun was the priest of Amun, he was most likely was in charge of these procedures. In the ancient Egyptian culture, the belief was that there was a life force and spirit inside of the body, known as the ‘Ka’. Therefore, mummification was performed as a ritual to preserve the physical features of the body as well as to protect its inner spirit, mainly to ensure that the ‘Ka’ could recognize the body where it may dwell in the eternal life. Thus, the funerary psychology of ancient Egyptians was that death did not bring an end to living, but instead was only an escape from the physical human life and a gateway to immortal being. Due to the fact that a being’s life span was short in ancient times, people’s main hopes rested in their afterlives, where they would be with the gods (Stockstad 121). Aside from being a priest, the importance of Paankhenamun’s position was due to his association with the Amun, who was a significant god of Egyptian Thebes. Viewed as chief divinity, Amun was often equated with the famous god Zeus and he even had his own worshiping cult (Freedman, 322). Moreover, Amun was originally one of the eight gods of Hermopolis, known as the god of air. However, at the time of the New Kingdom, this ch... ...rown, and in particularly gold. The gold color was used thoroughly, but due to ageing, it seemed to have changed shades and turned into brownish color (Freeman 321-2). An example of that could be illustrated by the face, which has a golden touch to it but is seen to be roughly all turning brown. These decorative features were also seen on other mummy coffins, such as on the coffin of Tutankhamun, found on the Valley of the Kings in Dynasty 18 (Stockstad 120-2). Tutankhamun’s case also demonstrated similar golden tones being used, which as a result of aging varnished and fainted in some areas to a darker golden- brownish and yellowish shade (Stockstad 123,125). The Mummy Case of Paankhenamun has great significant in that it provides us with very fundamental evidence from ancient history. It does not only exhibit a complex form of art, but it also demonstrates the religious practices of ancient Egyptians in association with their beliefs in life after death, as well as their great fascination with immortality. It not only teaches us about the great science of mummification, but it also provides us all with the incredible opportunity to learn about the life of an ancient person.

Gandhi and Comparative Religion Essays -- God Spirituality Papers

Gandhi and Comparative Religion Mahatma Gandhi was deeply interested in the comparative study of religions since the days of his youth.

Swot Analysis of Netflix

SWOT analysis for Netflix: Strengths: 1. Proprietary technology. Netflix has proprietary technology system to stream TV shows and movies and also including processing delivery and return DVDs. This specific system makes the business in Netflix more efficiency. 2. Goodwill and brand value. Netflix is a company with reputation. It has 15 years experiences and has a good deal of loyal consumers. 3. Competitive price. The service is in expensive in Netflix. It just cost 8 dollar per month and subscribers can enjoy unlimited viewing. 4. Simple service process.The service process in Netflix is simple. There are no commercials, no commitments, no contracts which can save consumer’s time and make the service more efficiency. 5. Open-minded managers. They continuously receive feedback from their consumers to change their strategy which makes the company more profitable and prevent many risks. 6. Good user experience. With just a little bit of timing, customers can have movies coming an d going so as to almost always have a movie ready to watch. Which generating loyal and enthusiastic customers. Weakness: 1.Third-party logistics or third-party device. Netflix have to rely on third-party logistics or third-party device, which mean if consumers lose confident with US mail system or some devices company, it will have bad effect on the reputation of Netflix. 2. Laws and government regulations. As an industry rely on internet, Netflix has to keep continual attention to laws and government regulations and make a quick reaction if something changed. 3. Pricing power. It has to accept the rates and delivery schedules set by the U. S. postal service, as well as the rates set by streaming providers. . Weak of internet system. As the main service of Netflix is completed on internet, there has the chance that the system to be attacked by hacker and it will bring tremendous negative effect on Netflix. 5. Debts. Netflix have issued $400 million in debt offerings and may incur ad ditional debt in the future, which may adversely affect their financial condition and future financial results. 6. Content distribution. These are not exclusive, which allowing competitors access to the same movies and television shows, leaving the way open for competition. Opportunities 1.Branding value. Netflix can become the first thing people think of for watching movies at home, just like â€Å"Google† is the first thing many think of for searching. There's been at least one instance of using the word â€Å"Netflix† as a verb, so this could be the beginning. 2. Technology changing. As the technology changing fast, Netflix can use continuously strategy changing to take the first mover advantage. 3. The big and increasing market. There have over 30 million members in over 50 countries enjoying over a billion hours of TV show and movies from Netflix every month.As the market is still increasing, there has a big opportunity for Netflix. 4. International expanding. As Netflix will expanding its domain outside United States, it will face many opportunities and challenges. 5. Distribution. As more subscribers come aboard, the value of Netflix as a distributor of content for studios goes up, leading to more pricing power for Netflix and less for the content producers. Threats 1. Competitors. That existing or new competitor  in the same domain, for example Google,YouTube and Amazon is the next most serious threat after Hulu. 2. Free ad-supported TV shows and movies. If large market segment bring for this kind of free TV shows and movies, the rate of growth in Netflix could be decline. 3. The liability for negligence, copyright or patent. Face the potential liability for content uploaded from their users. Netflix have the possible to be litigation if their consumers upload some videos illegal, which will cost Netflix a lot and will have negative results of their operation work. 4. The Copyright law change. If U.S. Copyright law were altered to amend or eliminate the First Sale Doctrine or if studios were to release or distribute titles on DVD in a manner that attempts to circumvent or limit the effects of the First Sale Doctrine, their business could be adversely affected. 5. Increasingly cost of their acquisition of DVD content and the logistic company. They are unable to negotiate with the studios because of consumers have lists and they have to buy the movies on the list. As labors cost more and more expensive the delivery DVDs cost is increasing. Risk 1.If Netflix efforts to attract and retain subscribers are not successful, their business will be adversely affected. 2. If Netflix unable to successfully or profitably compete with current and new competitors, programs and technologies, their business will be adversely affected, and they may not be able to increase or maintain market share, revenues or profitability. 3. If Netflix are unable to continue to recover from the negative consumer reaction to their price change and other announcements made during the third quarter of 2011, their business will be adversely affected. . If Netflix cannot foresee the consumer viewing habits exactly maybe it will make some wrong strategy and have adversely affected. 5. Many of their systems and operational practices were implemented when Netflix at a smaller scale of operations and they are undertaking efforts to migrate the vast majority of their systems to cloud-based processors. If they are not able to manage the growing complexity of their business, including improving, refining or revising our systems and operational practices, their business may be adversely affected. . The big portion of goodwill in its total asset is also a risk. If they cannot provide good service and make consumers satisfied, it will suffer a very bad influence for its profit. If they are unable to protect their domain names, their reputation and brand could be adversely affected. 7. Delayed availability of new release DVDs for rental co uld adversely affect Netflix’s business. In January 2012, Warner Home Entertainment announced it was increasing the period of delay to fifty-six days.If other studios were to increase the period of delay and /or if their subscriber satisfaction is negatively impacted by this increase in the Warner delay, their business could be adversely impacted. 8. Proprietary technology to stream TV shows and movies and to manage other aspects of their operations, including processing delivery and return of their DVDs to their subscribers, and the failure of this technology to operate effectively could adversely affect their business. . In the event of an earthquake or other natural or man-made disaster, Netflix’s operations could be adversely affected. They may not be able to effectively shift their fulfillment and delivery operations to handle disruptions in service arising from these events. 10. They could be subject to economic, political, regulatory and other risks arising from their international operations. 11. They may lose key employees or may be unable to hire qualified employees.

Computers the Good and the Bad

Computers Hold So Much Information; Sometimes Causing More Harm Than Good After reading a few short stories and conducting research on the subjects, I have found some interesting facts about how the computer has changed people’s lives. Computers have become the basis on which our society now depends; they are the key to communication, business, and success for many. Problems can arise however and privacy can be a major issue especially when it comes to certain websites such as MySpace and Facebook.Some people feel they have been violated of their rights and this is when the computer can become your worst enemy, not to mention how the computer has changed people’s ways of thinking and dealing with everyday tasks. â€Å"If it is a public forum that is accessible to others, then presumably the police are welcome to participate, as they would be welcome to enter a shopping mall or something like that†(Rotenberg). There are millions of users on websites such as Facebo ok and MySpace, these people are posting pictures, comments, and even communicating with friends and family.What many don’t realize, is that they are posting it for everyone to see. There have been incidents where the law has been involved in using these websites to catch criminals or even people who have been accused of a crime. â€Å"MySpace has encouraged it’s users to be aware that what they post on their profile is available for the public to see† (Mathew Grossman). MySpace and even Facebook have made it very clear that its users be aware of the risks they are taking by posting any personal information. They have settings which can be used to block certain users or to make your profile private.That way you can control who you want to see your page and interact with. The law has become involved in catching criminals or people involved in criminal acts by searching public profiles. They can read posts and even see pictures that an individual has posted, makin g it easier to get the persons personal information. They can get names and locations from the profile just by searching the page. And some are not aware that they are being searched this way. There have been issues with employers and their employees when it comes to the postings that are taking place for the public to see.Employers need to be aware of potential liability for employee’s publication of private information on Facebook and MySpace. For example a woman was convicted of cheating on her husband and accused of contracting an STD, her MySpace profile revealing these comments by others who claim it being true and stating it for everyone to see even other employees in her workplace. Working in the medical field where other employees were capable of retrieving her medical records she was now being tormented at work. The woman claimed invasion of privacy and took the case to court.The court suggested that since MySpace is public and considered a social network they canno t hold her employer liable for any accusations being brought against her by the employees on her profile. The MySpace page she claimed was made against her will and that her coworkers were to blame. This being questionable and not having proof as to who had actually posted it, nothing could be done. â€Å"Machines are being designed to serve explicitly as companions, pets, and tutors† (p 553, Turkle). Machines meaning computers are not only needed but we rely on them to do everyday tasks, we even depend on them to curve our boredom. At every step we need to ask, as educators and citizens, whether current technology is leading us in directions that serve our human purposes† (p 554, Turkle). Computers are used today to conduct work for businesses, pay our bills, communicate with others, even to play games and learn. Have they caused us to forget who we really? We spend hours upon hours on the computer and we sometimes can get so lost in the machine. For example, Susan a n euroscientist questions, of whether and how our current use of computers is changing the way our brains work.Susan finds that the visual stimuli we get from computers is so different from what is available in previous generations that certain areas of our brain may be affected in ways that can change personality and behavior. Few argue that when they turn from a computer back to a textbook they notice their concentration is lacking causing them some trouble to stay focused. The real problem caused by computer use is that we as human beings do not need to work as hard because the computer can do it for you, and the information is right there.This can be a problem especially for our youth, they will not have to do what it takes to use their brains and they will not have the thinking power or level of concentration we adults once needed. They will depend on the computer and computer only, to get things done. The Writers of these articles and short stories are showing their concern for the negative side of computers. They explain how people are being affected in certain situations due to issues of the computer and how their lives have been negatively affected. Each writer gave valid points and stated facts on the subjects when it came to using a computer.They explained the situations of each subject and the outcome of the issues being discussed. They supported the cases of how an individual can become a victim of false accusations on a profile and then being harassed by employees whom became involved in the woman’s personal life via MySpace or Facebook, and how the computer can damage our past ways of thinking and concentrating thus making it a lot harder to focus on everyday tasks that involve logical thinking. The writers clearly showed their concern and found existing facts on why a computer can and will affect people’s lives. The writers show that a computer must be used responsibly or there will be consequences.Works Cited 1. Alex Koppelman, MyS pace or Ourspace? (p546-557) ;The Bedford Guide to College Writers(X. J.

Changes And Urban Expansion In Greater Dhaka Environmental Sciences Essay

This survey evaluates old termland usage alterations and urban enlargement in Greater Dhaka, Bangladesh, between 1975 and 2003 utilizing satellite images and socio-economic informations. Spatial and temporal kineticss of old termlandnext term use/cover old termchangesnext term were quantified utilizing three Landsat images, a supervised categorization algorithm and the post-classification old termchangenext term sensing technique in GIS. Accuracy of the Landsat-derived old termlandnext term use/cover maps ranged from 85 to 90 % . The analysis revealed that significant growing of built-up countries in Greater Dhaka over the survey period resulted important lessening in the country of H2O organic structures, cultivated old termland, following term flora and wetlands. old termUrban land expansionnext term has been mostly driven by lift, population growing and economic development. Rapid old termurban expansionnext term through infilling of low-lying countries and glade of flora resulted in a broad scope of environmental impacts, including habitat quality. As dependable and current informations are missing for Bangladesh, the old termlandnext term usage maps produced in this survey will lend to both the development of sustainable old termurban landnext term usage planning determinations and besides for calculating possible hereafter old termchangesnext term in growing forms. Urbanization is one the most widespread anthropogenetic causes of the loss of cultivable old termlandnext term ( Lopez, Bocco, Mendoza, & A ; Duhau, 2001 ) , habitat devastation ( Alphan, 2003 ) , and the diminution in natural flora screen. The transition of rural countries into old termurbannext term countries through development is presently happening at an unprecedented rate in recent human history and is holding a pronounced consequence on the natural operation of ecosystems ( Turner, 1994 ) . Although old termurbannext term countries presently cover merely 3 % of the Earth ‘s old termlandnext term surface, they have marked effects on environmental conditions at both local and planetary graduated tables ( [ Herold etA al. , 2003 ] and [ Liu and Lathrop, 2002 ] ) , including clime old termchangenext term ( Grimm, Grove, Pickett, & A ; Redman, 2000 ) . Since ecosystems in old termurbannext term countries are strongly influenced by anthropogenetic activities, well more attendi ng is presently being directed towards supervising old termchangesnext term in old termurban landnext term usage and old termlandnext term screen ( LULC ) ( Stow & A ; Chen, 2002 ) . Such surveies are peculiarly of import because the spacial features of LULC are utile for understanding the assorted impacts of human activity on the overall ecological status of the old termurbannext term environment ( Yeh & A ; Li, 1999 ) . LULC old termchangenext term due to human activities is presently continuing more rapidly in developing states than in the developed universe, and it has been projected that by the twelvemonth 2020, most of the universe ‘s mega metropoliss will be in developing states ( World Bank, 2007 ) . Increasing population in developing metropoliss has caused rapid old termchangesnext term in LULC and increased environmental debasement ( Holdgate, 1993 ) . The consequence of population is peculiarly relevant given that the planetary old termurbannext term population is projected to about duplicate by 2050 ( UN, 2008 ) . In order to extenuate the damaging effects associated with old termurbannext term growing on the environment and to keep optimum ecosystem operation ( Fang, Gertner, Sun, & A ; Anderson, 2005 ) , spacial and temporal LULC forms, and the factors impacting these old termchangesnext term ( Serra, Pons, & A ; Sauri , 2008 ) , are well of import in developing rational economic, societal and environmental policies ( Long, Tang, Li, & A ; Heilig, 2007 ) . Bangladesh has experienced rapid old termurbannext term population growing in recent decennaries ; the population numbered 14.1 million in 1981, 22.5 million in 1991, 31.1 million in 2001 ( BBS, 2001 ) and 35 million in 2005 ( CUS, NIPORT, & A ; MEASURE, 2006 ) . Rapid urbanisation has led to the transmutation of rural countries into developed countries, and it has been estimated that more than 809A km2 of agricultural old termlandnext term is converted to metropoliss, roads and substructure yearly ( BBS, 1996 ) . The lessening in agricultural activities, the largest sector of the Bangladeshi economic system, and the attendant loss of cultivated old termlandnext term is likely to lend to landlessness, nutrient deficits and endanger the economic system ( Ahmad, 2005 ) . Dhaka, the capital of Bangladesh, is expected to be the 3rd largest metropolis in the universe by 2020 ( World Bank, 2007 ) and the rapid old termurbannext term growing experienced by the metropolis in recent decennaries is one of the highest in the universe ( [ Islam, 1999 ] and [ Islam, 2005 ] ) . old termUrban expansionnext term of Dhaka was slow in the 1950s, but strong growing followed the independency of Bangladesh in 1971 ( Chowdhury & A ; Faruqui, 1989 ) . The considerable growing observed in the population of Dhaka is thought to hold occurred in response to large-scale rural-previous termurbannext term migration, which has contributed, significantly to the increased rate of urbanisation ( Islam, 1996 ) . To day of the month, the environmental and socio-economic sustainability of Dhaka, which is indispensable for development planning, has received comparatively small attending. This has resulted in widespread environmental jobs across the metropolis, mostly stemming from unpl anned urbanisation, extensive old termurbannext term poorness, perennial episodes of implosion therapy, significant growing of slums, development of resources, and the misdirection of limited old termlandnext term resources ( Hasan & A ; Mulamoottil, 1994 ) . Geographic Information Systems ( GIS ) and distant detection ( RS ) are powerful and cost-efficient tools for measuring the spacial and temporal kineticss of LULC ( [ Hathout, 2002 ] , [ Herold etA al. , 2003 ] , [ Lambin etA al. , 2003 ] and [ Serra etA al. , 2008 ] ) . Distant feeling informations provide valuable multi-temporal informations on the procedures and forms of LULC old termchange, following term and GIS is utile for function and analysing these forms ( Zhang etA al. , 2002 ) . In add-on, retrospective and consistent synoptic coverage from orbiters is peculiarly utile in countries where old termchangesnext term have been rapid ( Blodget, Taylor, & A ; Roark, 1991 ) . Furthermore, since digital archives of remotely sensed informations provide the chance to analyze historical LULC old termchanges, following term the geographic form of such old termchangesnext term in relation to other environmental and human factors can be evaluated. Numerous old termchangenext term sensing methods have been developed to measure fluctuations in LULC utilizing satellite informations ( [ Coppin etA al. , 2004 ] , [ Lu etA al. , 2004 ] and [ Singh, 1989 ] ) . Of these techniques, the pre- and post-classification comparings have been extensively used ( [ Coppin etA al. , 2004 ] and [ Singh, 1989 ] ) . In the pre-classification attack, processs such as image differencing ( Toll, Royal, & A ; Davis, 1980 ) , band rationing ( Nelson, 1983 ) , old termchangenext term vector analysis ( Johnson & A ; Kasischke, 1998 ) , direct multi-date categorization ( Li & A ; Yeh, 1998 ) , flora index differencing ( Townshend & A ; Justice, 1995 ) and principle constituent analysis ( Fung & A ; LeDrew, 1987 ; Hartter, Lucas, Gaughan, & A ; Aranda, 2008 ) have been developed ( [ Hardin etA al. , 2007 ] , [ Jensen, 1996 ] and [ Singh, 1989 ] ) . The basic premiss of these processs is that old termchangesnext term in LULC consequence in differences in the pel coefficient of reflection values between the day of the months of involvement. However, while these techniques are effectual for turn uping old termchange, following term they can non place the nature of old termchangenext term ( Ridd & A ; Liu, 1998 ) . Conversely, post-classification comparings examine old termchangesnext term over clip between independently classified old termlandnext term screen informations. Despite the troubles associated with post-classification comparings ( [ Coppin etA al. , 2004 ] and [ Singh, 1989 ] ) , this technique is the most widely used for placing LULC old termchangesnext term ( [ Jensen, 1996 ] and [ Lu etA al. , 2004 ] ) , peculiarly in old termurbannext term environments ( Hardin etA al. , 2007 ) . However, one of the disadvantages associated with this attack is that the truth of the end point LULC old termchangenext term maps depends on the truth of the single categorization, intending that such techniques are capable to error extension ( Y uan, Sawaya, Loeffelholz, & A ; Bauer, 2005 ) . However, such post-classification techniques are peculiarly utile for bring forthing ‘from-to ‘ maps ( Jensen, 1996 ) , which can be used to clear up the magnitude, location and nature of the old termchangesnext term shown ( Howarth & A ; Wickware, 1981 ) . In add-on, the technique can be employed utilizing informations acquired from detectors with different spatial, temporal and spectral declarations ( [ Alphan, 2003 ] and [ Coppin etA al. , 2004 ] ) . RS is really effectual for exemplifying the interactions between people and the old termurbannext term environments in which they live ( Gatrell & A ; Jensen, 2008 ) . Space-borne orbiter informations are peculiarly utile for developing states due to the cost and clip associated with traditional study methods ( Dong, Forster, & A ; Ticehurst, 1997 ) , and these techniques have become feasible options to conventional study and ground-based old termurbannext term mapping methods ( Jensen, Hodgson, Tullis, & A ; Raber, 2004 ) . Several surveies have demonstrated the pertinence of RS to developing sourcing information and for back uping decision-making activities in a broad scope of old termurbannext term applications ( [ Gatrell and Jensen, 2008 ] , [ Jensen and Cowen, 1999 ] and [ Zeilhofer and Topanotti, 2008 ] ) . In the country of old termurbannext term planning, of import RS research has been conducted to day of the month, peculiarly in old termurban changenext term analysis and th e mold of growing ( [ Bahr, 2004 ] , [ Hardin etA al. , 2007 ] , [ Hathout, 2002 ] , [ Herold etA al. , 2003 ] , [ Jat etA al. , 2008 ] , [ Jensen and Im, 2007 ] , [ Liu and Lathrop, 2002 ] , [ Maktav and Erbek, 2005 ] , [ Ridd and Liu, 1998 ] , [ Yang, 2002 ] and [ Yuan, 2008 ] ) , LULC rating ( [ Alphan, 2003 ] , [ Lopez etA al. , 2001 ] , [ Xiao etA al. , 2006 ] , [ Yang and Lo, 2002 ] and [ Yuan etA al. , 2005 ] ) , and old termurbannext term heat-island research ( [ Kato and Yamaguchi, 2005 ] and [ Weng, 2001 ] ) . In peculiar, RS-based multi-temporal old termlandnext term use old termchangenext term informations provide information that can be used for measuring the structural fluctuation of LULC forms ( Liu, Gao, & A ; Yang, 2003 ) , which can be applied to avoiding irreversible and cumulative effects of old termurbannext term growing ( Yuan, 2008 ) and are of import to optimise the allotment of old termurbannext term services ( Barnsley & A ; Barr, 1996 ) . In add-on, accura te and comprehensive old termlandnext term use old termchangenext term statistics are utile for inventing sustainable old termurbannext term and environmental planning schemes ( [ Alphan, 2003 ] and [ Jensen and Im, 2007 ] ) . It is hence really of import to gauge the rate, form and type of LULC old termchangesnext term in order to foretell future old termchangesnext term in old termurbannext term development. Small is known about the spacial and temporal dimensions of the LULC old termchangesnext term that have shaped the old termurban expansionnext term of Greater Dhaka. Although most developed states have both recent and extended LULC information, the comparative deficiency of geospatial informations or entree thereto, is prevailing in developing states, peculiarly in Bangladesh. For case, aerial exposure are classified for the populace. The metropolis does non hold any official statistics on old termlandnext term usage forms, and the Master Plans do non incorporate either a map or quantitative information on the bing forms of old termlandnext term usage in the metropolis ( [ Islam, 1996 ] and [ Islam, 2005 ] ) . The old termlandnext term usage forms of Greater Dhaka were officially categorized in 1991 utilizing land observation informations ( Flood Action Plan ( FAP ) 8A, 1991 and [ Islam, 2005 ] ) . Due to the easiness of entree and recent nature of nose count records, the local autho ritiess of Dhaka often use nose count informations to construe old termlandnext term use old termchanges.next term As a consequence, the kineticss of development are non clear and frequently deceptive ( Talukder, 2008 ) . Numerous factors, including fiscal restraints, restricted entree to informations, bureaucratism and deficiency of geospatial expertness in the planning bureaus account for the absence of historical and current old termlandnext term usage informations. Furthermore, every bit many as 18 ministries are involved in the development and planning of Dhaka, and there is a general deficiency of coordination between these organic structures ( Mohit, 1991 ) . This empirical survey will try to place the spatio-temporal form of LULC old termchangesnext term for Greater Dhaka utilizing geospatial informations so that both the scientific community and determination shapers can measure the assorted kineticss impacting LULC old termchangesnext term in this old termurbannext term en vironment. The aims of this survey were therefore to research the features of LULC old termchangesnext term and qualify the underlying drive forces in the Greater Dhaka country by doing usage of remotely sensed informations and socio-economic information. Specifically, the aims are: ( a ) to clarify and measure the LULC old termchangesnext term between 1975 and 2003 ; ( B ) to research the spacial and temporal features of old termurban expansionnext term in this period ; and ( degree Celsius ) to analyse the drive forces of old termlandnext term use old termchange and urban expansion.next termStudy countryAs shown in Fig.A 1, the survey country of Greater Dhaka is located in the centre of Bangladesh between 23A °68aˆ?N ( BTM 533233.91A m ) , 90A °33aˆ? E ( BTM 619052.83A m ) and 23A °90aˆ?N ( BTM 550,952.57A m ) , 90A °50aˆ? E ( BTM 642511.56A m ) , severally. Topographically, the country is level with a surface lift runing from 1 to 14A m ( Fig.A 1 ) , with most old ter murbannext term countries located at lifts runing from 6 to 8A m ( FAP 8A, 1991 ) . The metropolis is situated chiefly on an alluvial patio, popularly known as the Modhupur patio dating from the Pleistocene period. The survey country is surrounded by four major river systems: the Buriganga, Turag, Tongi and the Balu, which flow to the South, west, north and east, severally. These rivers are chiefly fed by local rainfall and besides receive overflow from the well larger Ganges, Brahmaputra and Meghna rivers. The metropolis has a humid sub-tropical monsoon clime and receives about 2000A millimeters of rainfall yearly, more than 80 % of which falls during the monsoon season from June to September.

River webs, embankment and administrative units are draped over a digital lift theoretical account. Brightest countries represent higher lift ; bright grey represents average lift while dark pels show the lowest lift.Position Within ArticleThe happening of heavy monsoon rainfall combined with floodwater overflow from the rivers environing the metropolis mean that Dhaka is really prone to monsoon implosion therapy. The metropolis has experienced a figure of lay waste toing inundations in recent times, with the inundations in 1988, 1998 and 2004 being the most terrible ( Alam & A ; Rabbani, 2007 ) . Quantitative appraisals of the countries inundated by these flood events revealed that in 1988, 47.1 % of greater Dhaka were flooded, while in 1998 and 2004, about 53 % and 43 % countries were inundated ( [ Dewan etA al. , 2007 ] , [ Dewan and Yamaguchi, 2008 ] and [ Dewan etA al. , 2006 ] ) . The inundations caused harm to lodging and substructure amou nting to US $ 2.2A m in 1988, 4.4A m in 1998 and 5.6A m in 2004 ( Ahmed, Gotoh, & A ; Hossain, 2006 ) . The badness of inundation harm was considerable, even in 2004, which was considered more moderate of the three inundations, and which was believed to be the consequence of hapless old termurbannext term planning and renewal and development of natural countries, such as wetlands and low-lying countries, that would otherwise hold attenuated the implosion therapy. A survey utilizing hydrological record and RS-based LULC information has shown that inundation continuance and extent has increased well as a consequence of the extended old termurbannext term development on Lowlandss and flood plains of natural river channels ( Dewan & A ; Yamaguchi, 2008 ) . It has been suggested that the exposure of Dhaka to deluge harm will increase due to continued unplanned old termurban expansionnext term ( Faisal, Kabir, & A ; Nishat, 1999 ) and the consequence of clime old termchangenext term ( Ala m & A ; Rabbani, 2007 ) , and that these in bend will increase the agony to the dwellers of Dhaka and do extended harm to belongings in the part.Data and methodological analysisData acquisition and readyingLandsat informations ( MSS, TM and ETM+ ) were acquired and used to measure LULC old termchanges and urban expansionnext term in Dhaka. Geometric rectification was performed on all the images utilizing a Landsat TM image of the same country from 1997 as mention. At least 45 land control points ( GCPs ) were used to register the images to the Bangladesh Transverse Mercator ( BTM ) system. GCPs were dispersed throughout the scene, giving a RMS mistake of less than 0.5 pels. A first order multinomial tantrum was applied and images were resampled to 30A m end product pels utilizing the nearest neighbour method. All brooding sets were used in image categorization and the thermic set was excluded. In add-on, geospatial informations including municipal boundaries, route webs, geomorphic units and lift units were used to bring forth GIS beds from beginnings such as Survey of Bangladesh ( SOB ) topographical maps ( sheet no. 79 I 5 & A ; 6 ) , municipal boundary map and geomorphic map ( Asaduzzaman, Nasreen, & A ; Olsen, 1999 ) . Multi-year socio-economic informations were obtained from Bangladesh Bureau of Statistics ( BBS ) and published literature ( [ Islam, 1996 ] , [ Islam, 2005 ] and [ Siddiqui etA al. , 2000 ] ) . Reference informations, which varied given the retrospective nature of the survey ( Table 1 ) , were used for both developing country choice and for the rating of map truth. In add-on to utilizing high-resolution imagination, intensive fieldwork was conducted in the survey country from 6 February to 22 March 2003 to roll up land truth information for the analysis of the 2003 image. A hardcopy false colour composite ETM+ ( RGB 432 ) image picturing different LULC types was used in the field to place bing old termlandnext term screen characteristics, with particular attending given to spectrally similar characteristics. Based on this fieldwork, a land truth map was prepared for turn uping preparation pels on the image and 200 mention informations points were collected utilizing a planetary placement system ( GPS ) . This GPS information was so overlaid with the image in GIS to choose developing countries and for accuracy appraisal ; 100 of the GPS points were used for trying and the ot her 100 were used for measuring the truth of the categorization.

Specifically, extra factors such as the major old termlandnext term usage classs within the survey country and differences in the spacial declaration of the images, which varied from 30 to 79A m, were considered in planing the categorization strategy. Six separate LULC types were identified: H2O organic structures, wetlands/lowlands, built-up countries, cultivated old termland, following term flora and bare soil/landfill ( Table 2 ) . Table 2. old termLandnext term use/cover categorization strategy. old termLandnext term use/Cover TypesDescriptionBuilt-up Residential, commercial and services, industrial, transit, roads, assorted old termurban, following term and other old termurbannext term Bare soil/landfill sites Exposed dirts, landfill sites, and countries of active digging Cultivated old termlandnext term Agricultural country, harvest Fieldss, fallow old termlandsnext term and vegetable old termlandsnext term Vegetation Deciduous forest, assorted forest old termlands, following term thenars, conifer, chaparral and others Water organic structures River, lasting unfastened H2O, lakes, pools and reservoirs Wetland/lowlands Permanent and seasonal wetlands, low-lying countries, marshy old termland, following term rivulets and gully, swamps Full-size tabular arrayPosition Within ArticleAll orbiter informations were studied utilizing spectral and spacial profiles to determine the digital Numberss ( DNs ) of different LULC classs prior to categorization. Training samples were selected from the mention informations and accessory information ( Table 1 ) . Sixty to seventy preparation sites, runing in size from 286 to 7800 pels, were used to develop the images. Training samples included 5-10 subclasses for each category except for bare soil/landfill. The preparation samples were so refined, renamed, merged, and deleted after rating of the category histogram and statistical parametric quantities. A supervised upper limit likeliness categorization ( MLC ) algorithm, antecedently demonstrated to obtain the best consequences from remotely sensed informations if each category has a Gaussian distribution ( Bolstad & A ; Lillesand, 1991 ) , was so applied to each image. However, several of the categories were falsely classified in the supervised categorization of LULC, with certain old termurbannext term colonies being misclassified as landfill sites due to their holding similar spectral features. Similarly, the wetland category was merged with the lowland category as it was non possible to divide them due to similar spectral belongingss, and the wetland/lowland class and cultivated old termlandnext term were besides falsely classified. Post-classification polish was hence used to better the truth of the categorization as it is a simple and effectual method ( Harris & A ; Ventura, 1995 ) . In add-on, since the old termurbannext term surface is heterogenous and composed of a complex combination of characteristics ( e.g. edifices, roads, grass, trees, dirt, H2O ) ( Jensen, 2007 ) , assorted pels are a common job when utilizing medium-spatial declaration informations such as Landsat ( Lu & A ; Weng, 2005 ) . The job of assorted pels was addressed in several ways. For illustration, thematic information ( e.g. H2O organic structures, flora, and bare dirt ) was foremost extracted from the Landsat informations utilizing the V-S-W index ( Yamagata, Sugita, & A ; Yasuoka, 1997 ) , before a rule-based technique utilizing thematic information and GIS informations ( e.g. DEM, municipal maps and H2O organic structures, etc. ) was employed in ERDAS spacial modeller to rectify antecedently misclassified old termlandnext term scree n classs. Although this rule-based technique greatly improved the MLC categorization, some misclassification between wetland and cultivated old termlandsnext term was still observed, chiefly because of the geographical adjacency of these classs. GIS tools, such as Area of Interest ( AOI ) were so applied to the informations utilizing ocular analysis, mention informations, every bit good as local cognition, to divide and recode these screens so that they more closely reflected their true categories. By using these techniques, the consequence obtained utilizing the supervised algorithm could be well improved. Finally, to cut down the salt-and-pepper consequence, a 3A A-A 3 bulk filter was applied to the classified old termlandnext term screens ( Lillesand & A ; Kiefer, 1999 ) .Accuracy appraisalBy and large, categorization truth refers to the extent of correspondence between the remotely sensed informations and mention information ( Congalton, 1991 ) . In order to measure the truth of old termlandnext term screen maps extracted from Landsat informations, a sum of 125 graded random pels were generated for the 1975 and 1992 informations and 100 pels for the 2003 old termlandnext term screen map. Accuracy appraisal of the LULC maps was so performed utilizing field informations and the geographical characteristics on old termlandnext term usage maps, high-resolution images, and SOB topographic maps, and the consequences were recorded in a confusion matrix. A non-parametric Kappa trial was besides used to mensurate the categorization truth as it accounts for all the elements in the confusion matrix instead than merely the diagonal elements ( Rosenfield & A ; Fitzpatirck-Lins, 1986 ) . The entire truth of the Landsat-derived LULC information was 85.6, 89.6 and 90 % with matching Kappa statistics of 82.7, 87.5 and 87.9 % for MSS, TM and ETM+ , severally, confirming the standard truth of 85-90 % for LULC mapping surveies as recommended by Anderson etA Al. ( 1976 ) . The application of rule-based post-classification polish was found to be effectual and improved truth by 10-12 % . The MSS image had the lowest overall truth, which may be due to its harsh spacial declaration ( Haack, 1987 ) . Yang and Lo ( 2002 ) besides noted that the jobs associated with right sorting assorted pels additions with diminishing image declaration, ensuing in spectral confusion. In this survey, spectral confusion was higher in the MSS image than in the TM/ETM+ images. old termChangenext term sensing This survey employed the post-classification old termchangenext term sensing technique, which is efficient in observing the nature, rate and location of old termchanges, following term and has been successfully used by a figure of research workers in the old termurbannext term environment ( Hardin etA al. , 2007 ) . An overlay process utilizing the GIS was adopted in order to obtain the spacial old termchangesnext term in LULC during three intervals: 1975-1992, 1992-2003 and 1975-2003. Application of this technique resulted in a bipartisan cross-matrix, depicting the chief types of old termchangenext term in the survey country. Cross tabular matter analysis on a pixel-by-pixel footing facilitated the finding of theA measure of transitions from a peculiar old termlandnext term screen category to other old termlandnext term usage classs and their corresponding country over the period evaluated. A new thematic bed incorporating different combinations of â€Å" from-to † old termc hangenext term categories was besides produced for each of the three six-class maps. LULC old termchangesnext term and kineticss of old termurban expansionnext term Spatial forms of LULC old termchangesnext term in the Greater Dhaka country for 1975, 1992 and 2003 are shown in Fig.A 2. In 1975, lowlands, cultivated countries and H2O organic structures were the dominant old termlandnext term usage types, and the way of old termurban expansionnext term ( herein referred to as the built-up class ) was northerly. In 1992, the built-up class replaced most of the H2O organic structures and depressions within the metropolis every bit good as the cultivated old termlandnext term along the peripheral zone. Surveies of historical maps and the available literature suggest that the depressions and H2O organic structures within the metropolis disappeared comparatively rapidly after independency as countries were developed for residential, commercial, academic and concern intents ( Siddiqui etA al. , 2000 ) . Between 1975 and 1992, when route transit from Dhaka to the backwoods was improved by the building of Bridgess over the rivers ( Islam, 1996 ) , old ter murban expansionnext term extended further to the North, north-west and to the West. Consequently, the country of cultivated old termlandnext term and H2O organic structures declined markedly during the period 1975-1992 ( Louis Berger & A ; BCL, 2005 ) . In 2003, the forms of LULC old termchangenext term revealed that Dhaka started to spread out in all waies, chiefly at the disbursal of vegetated and wetland/lowland countries. The rate of old termurbannext term invasion ( Fig.A 2 ) on other old termlandnext term utilizations increased significantly following the readying of a new Master Plan in 1995 and the development of substructure ( Siddiqui etA al. , 2000 ) . The building of a span over the Buriganga River accelerated old termurban expansionnext term in the southern and northwesterly waies. The spacial distribution of the exposed soil/landfill class is besides seeable in the maps produced ( Fig.A 2 ) , clearly exemplifying the transmutation of lowland countries to landfills on the outskirts of Dhaka. Life-size image ( 292K ) – Opens new window Life-size image ( 292K ) Fig.A 2.A Classified old termlandnext term use/cover maps of Greater Dhaka in 1975, 1992 and 2003.Position Within ArticleThree sectors, viz. the populace, private, and individual-household sectors, are responsible for all of the old termlandnext term developments in Dhaka. Most of the old development undertakings were undertaken on an ad hoc footing by the populace sector, chiefly in countries that were antecedently used for agribusiness and that were free from flood ; illustrations of such developments include Gulshan Model Town, Banani, Uttara Model Town and Dhanmondi ( Chowdhury, 2003 ) . In recent old ages, belongings development has proliferated in Dhaka, and belongings developers have developed both wetlands and agricultural countries without any consideration of the attendant environmental costs. In add-on, single families have started to develop the peripheral countries ( Islam, 1996 ) . In the fieldwork conducted in this survey, old termlandnext term guess was observed to ho ld had a pronounced influence on the development of suburban countries. In response to increasing old termlandnext term monetary values and turning demand for lodging, Lowlandss and agricultural countries in the periphery zone are quickly going built-up by the person and belongings developers. While suburban development is a really complex procedure that is known to be influenced by a assortment of factors, including guess and old termlandnext term monetary values, these factors may non adequately explicate the procedure of suburban development in the survey country. A more elaborate survey is hence required in order to understand the assorted factors act uponing suburban development in the greater Dhaka country. Furthermore, hapless coordination among executive bureaus is besides responsible for the decrease observed in natural resources in the survey country. For illustration, in the Dhaka-Narayangonj-Demra ( DND ) undertaking, despite about 6000A hour angles being set aside for a gricultural production in the 1960s, the country has been used by local and migratory people for residential intents since 1990s without any blessing from the governments concerned. Cases such as this illustrate the deficiency of effectual coordination among the organisations involved in the planning and development of Dhaka. Analysis of the LULC old termchangesnext term in Dhaka over clip revealed a considerable addition in the built-up countries over the survey period ; built-up countries increased by 6132A hour angle between 1975 and 1992, which is an norm of more than 360A haA yra?’1. Similarly, built-up countries increased in size by 4422A hour angle from 1992 to 2003, more than 400A haA yra?’1, and the net addition of old termurbannext term countries over the survey period was 10554A hour angle ( Table 3 ) . When compared with other metropoliss in the part, such as Ajmer City in India, the rate of the old termurban expansionnext term in Ajmer City was 29.2A haA yra?’1 over the period 1977-1989 and 32.4A haA yra?’1 from 1989 to 2002 ( Jat, Garg, & A ; Khare, 2008 ) . Although urbanisation is by and large related to demographic old termchangenext term and economic growing ( Li, Sato, & A ; Zhu, 2003 ) , the nature of old termurban expansionnext term in the survey country ma y besides be associated with other factors such as topography, old termlandnext term usage, and transit. Close scrutiny of the old termchangenext term sensing statistics revealed that about 6132A hour angle of the urbanised country in Dhaka were antecedently either agricultural countries or H2O organic structures between 1975 and 1992. Conversely, 4422A hour angle of the freshly urbanized countries were antecedently flora or wetlands during the same period. By and large, two factors were observed to hold promoted old termurbannext term growing: ( 1 ) increased economic activity associated with the constitution of economic zones ( e.g. export treating zone ) and ( 2 ) redefinition of the metropolitan country. Between 1975 and 1992, reclassification of old termurbannext term countries every bit good as infrastructural development played a important function in the old termexpansion of urbannext term countries. For case, the nor'-west and southerly old termexpansionnext term of the met ropolis occurred in response to building of a inundation embankment in 1992 ( Fig.A 1 ) and a span on the Buriganga River in 2001. The spacial features of built-up countries have besides been shaped by the building of a figure of transit paths in the same period, as understood from historical map analysis and field visit. The old termexpansionnext term to the E and nor'-east led to the development of unplanned suburbs in the Lowlandss and agricultural countries that were antecedently located in those countries.

Another important old termchangenext term was the diminution in wetlands and flora from 1992 to 2003. In 1992, wetlands and flora occupied 28 % and 13.7 % of the entire survey country, but by 2003, these countries had declined to 21.7 % and 5.5 % , severally. Conversely, built-up countries increased in size by 37.9 % in the period from 1992 to 2003. A little addition in cultivated old termlandnext term ( 6.7 % ) was besides observed in this period. The diminution of flora and wetlands was clearly due to intensification of old termurbannext term development in the greater Dhaka country, peculiarly through the procedure of suburban development. As shown in Table 4, there has been a pronounced old termchangenext term in LULC ove r the 28-year survey period. Table 4.

The procedure of old termurban expansionnext term in Dhaka was observed to change markedly over the old ages examined in this survey ; specifically, the metropolis expanded by 6131.9A hour angle during the 17-year period from 1975 to 1992 and 4422.2A hour angle in the 11-year period from 1992 to 2003. Landsat images revealed that old termurban expansionnext term in two periods examined in this survey did non happen equally in all waies ; new developments were observed along the fringe of old termurbannext term countries every bit good as in the countries that had already been urbanized. The rapid gait of urbanisation in Dhaka means that it has non been possible for the municipal authorities to supply basic old termurbannext term comfortss to the population, which has led to a broad scope of environmental jobs. For illustration, old termurbannext term development facilitated by old termlandnext term filling has been shown to hold a negative impact on natural home ground and biodiversity ( [ Alphan, 2003 ] and [ Dewidar, 2002 ] ) . Vulnerability to temblor related jeopardies has besides increased since a major part of Dhaka ‘s recent development has taken topographic point in landfill sites ( Kamal & A ; Midorikawa, 2004 ) . In southern Dhaka, landfills have contributed to dir ty pollution, ensuing in reduced flora ( Khatun & A ; Hoque, 1994 ) . Uncoordinated urbanisation and the creative activity of landfill sites have intensified the extent of flood in the metropolis during the moisture season ( Alam & A ; Rabbani, 2007 ) , which is peculiarly critical in the western parts of Dhaka ( Maathuis, Mannaerts, & A ; Khan, 1999 ) . Flood hazard potency has been elevated due to continued infilling of H2O organic structures, wetlands and low-lying countries ( Dewan & A ; Yamaguchi, 2008 ) . In add-on, the speed uping growing of slums is impacting the metropolis ‘s physical and human environment. Harmonizing to CUS etA Al. ( 2006 ) , the slum population of Dhaka ( about 37 % of the metropolis ‘s population ) has doubled in a decennary, to make 3.4 million in 2006 from 1.5 million in 1996. The environment of these informal colonies is highly unhygienic as they are in close propinquity to solid waste mopess, unfastened drains and cloacas, embankments, a nd along railroad lines ( Islam, 1999 ) . Consequently, the people populating in slums are highly vulnerable to inundations ( Rashid, 2000 ) and they besides suffer from an acute deficit of drinkable H2O ( Akbar, Minnery, Horen, & A ; Smith, 2007 ) .Driving forces analysisLULC old termchanges and urban expansionnext term of Greater Dhaka is governed by a combination of geographical, environmental and socio-economic factors. Although population growing is the primary cause for rapid urbanisation, the part of other causes such as economic development and physical factors besides needs to be assessed. To measure the mechanisms underlying the old termchangesnext term in LULC and subsequent old termurban enlargement, following term we performed a arrested development analysis of built-up countries utilizing selected physical and socio-economic variables ( lift, incline, population and GDP ) , and presented the consequences in Table 5. old termUrbannext term country informations were extr acted from one-year BBS statistics since RS informations merely cover three old ages. To analyze the effects of incline and lift on old termurban enlargement, following term average values of incline, and lift of both developed and developing countries in the metropolis were calculated from a digital lift theoretical account. Socio-economic informations, such as population and GDP values were obtained from the decadal and annually one-year tabular arraies of the Bangladesh Bureau of Statistics ( Table 1 ) . Table 5.

By 1981, the population had reached 3.44 million. The population reached 6.92 million in 1991 and 10.7 million by 2001 ( BBS, 2001 ) . Presently, the population of Dhaka is more than 12 million with an one-year mean growing of 5 % , compared to the national growing of 2.1 % ( Bangladesh Bureau of Statistics ( BBS ) , 2005 and [ The World Bank, 2007 ] ) . The rapid growing of the old termurbannext term population has chiefly resulted from rural-previous termurbannext term migration and estimates show that more than 60 % of people in Dhaka have migrated from rural countries ( Islam, 1991 ) . Intelligibly, this addition in the population had the consequence of i ncreasing force per unit area on the limited resource-base, and significantly contributed to the old termexpansion of urbannext term countries by glade of natural flora and infilling of low-lying countries. Table 5 clearly shows that old termurban expansionnext term is positively related to population growing. Dhaka ‘s economic development is another factor that has contributed to rapid urbanisation. For illustration, Dhaka ‘s gross domestic merchandise ( GDP ) was about 11,312 million Taka1 in 1976, 129,665 million Taka in 1992 and 162,490 million Taka in 1995. Presently, the GDP of Dhaka is 354,240 million Taka and the metropolis ‘s portion of the national economic system is 19 % ( BBS, 2005 ) . The economic development associated with the roar in ready-made garments since the 1980s has had a important impact on old termexpansionnext term of the metropolis country. This economic activity has besides resulted in a big inflow of rural-previous termurbannext term migrators in the same period ( Islam, 1996 ) . In add-on, Dhaka supports more than 40 % of Bangladesh ‘s industry, farther suggesting that the economic development and industrialisation has led to a higher rate of old termurban expansion.next term The arrested development analysis revealed that GDP exercised positive effects on old termurban land expansionnext term ( Table 5 ) . As in other old termurbannext term centres, the way of old termurban expansionnext term in Dhaka has been extremely influenced by its physical scene, peculiarly its topography. The four major rivers, swamps and depressions within and around the metropolis have ever played a polar function in the development of built-up countries in the metropolis. Urbanization ab initio occurred in the elevated countries that were non affected by inundation. Once all the elevated places had been developed, the lifting demand of old termurban landnext term has been met by the transmutation of low-lying countries, vegetated countries and wetlands. The development of wetlands, for case, has led to a significant loss of natural resources and an addition in habitat debasement. The growing of belongings developers has accelerated invasion of old termurbannext term countries on wetlands and threatens biodiversity. Two geophysical indexs were used in the arrested development analysis ( Table 5 ) and found th at lift has major influence on old termurban expansionnext term while incline has non passed the important trial.DecisionsThis survey has assessed LULC old termchangesnext term and the kineticss of old termurban expansionnext term in Greater Dhaka, Bangladesh utilizing RS informations in concurrence with socio-economic variables. old termUrban expansionnext term was quantified for the last 28 old ages utilizing the post-classification comparing technique. Greater Dhaka was found to hold experienced rapid old termchangesnext term in LULC, peculiarly in built-up/previous termurbannext term countries. Analysis revealed that old termurbannext term countries increased by 6131A hour angle during 1975-1992 and 4422A hour angle from 1992 to 2003, which resulted in a significant decrease in the country of H2O organic structures, flora, cultivated countries and wetlands/lowland. The dramatic old termexpansion of the urbannext term countries of Dhaka exhibited clear spatio-temporal differences . The transition of H2O organic structures, flora and low-lying countries to old termurban landnext term has caused extended and varied environmental debasement in the survey country, and the exposure to implosion therapy and the growing of slums have been the chief negative results associated with the rapid old termurbannext term development. old termUrban land expansionnext term has been mostly driven by lift, population growing and economic development. Integrated usage of GIS, RS and socio-economic informations could therefore be efficaciously used to understand the spatial and temporal kineticss of LULC old termchanges.next term The reading and categorization of RS informations were utile for gauging the rate and spacial form of the old termurban expansionnext term in Greater Dhaka of Bangladesh. As dependable and current informations are missing for Bangladesh, the old termlandnext term usage maps produced in this survey will lend to both the development of sustainable old termurban landnext term usage planning determinations and besides for calculating possible hereafter old termchangesnext term in growing forms.
