St. Anselmââ¬â¢s version of the Ontological Argument and Gauniloââ¬â¢s objection to it Essay Example
St. Anselmââ¬â¢s version of the Ontological Argument and Gauniloââ¬â¢s objection to it Paper Anselm of Canterbury was one of the early promoters of the Ontological Argument supporting the existence of God. He argues that God exists on the basis that ââ¬Ësomething-than-which-nothing-greater-can-be-thoughtââ¬â¢ should necessarily exist in reality. In other words, just as anything a painter can conceive of can be materialized into a painting, the conception of God is a terminal point for human imagination. To the extent that it is imaginable, the object exists. To the extent that it is the ultimate in the scale of imagination, it must be God. Anselm goes on to claim that that God cannot be thought not to exist is further proof. He says, ââ¬Ësomething-than-which-a-greater-cannot-be-thoughtââ¬â¢ exists so truly that it cannot even be thought not to exist. If a creature is able to think of something better and bigger than God, it would have to be above its Creator and be judging its Creator. Since this is logically impossible, it is only God who not only truly exists b ut also exists to the highest degree. Anselm goes on to point to an apparent contradiction in the foolââ¬â¢s (nonbeliever) thinking. He asks rhetorically ââ¬Å"How indeed has he ââ¬Ësaid in his heartââ¬â¢ what he could not think; or how could he not think what he ââ¬Ësaid in his heartââ¬â¢, since to ââ¬Ësay in oneââ¬â¢s heartââ¬â¢ and to ââ¬Ëthinkââ¬â¢ are the same?â⬠(Anselm, p.21) And finally, Anselm posits that God is whatever it is better to be than not to be and that, ââ¬Å"existing through himself alone, he makes all other beings from nothingâ⬠. (Anselm, p.21) Gaunilo of Marmoutiers makes a strong case on behalf of the fools. He makes a point-to-point rebuttal of the claims of Anselmââ¬â¢s Ontological Argument. Gaunilo counters that that-which-is-greater-than-everything should actually exist in reality just as it exists in the mind. It cannot simply be assumed, as the Ontologists have done, that God must exist because he is that entity which is conceived to be greater-than-everything. Gaunilo makes another salient observation about human cognition and human intelligence. Gaunilo goes on to clarify the example of the painter. The painting, at the time of its conception, is the product of the artistââ¬â¢s creativity and is thus an integral part of his very understanding. This understanding is not the same as the ultimate truth that God represents. Hence, even granting that ââ¬Ëthere-was-something-than-which-nothing-greater-could-be-thoughtââ¬â¢, ââ¬Å"this thing, heard and understood, would not, however, be the same as the not-y et-made picture is in the mind of the painterâ⬠. Moreover, when it is said that God cannot be thought not to exist, it is prudent instead to say that it ââ¬Å"cannot be understood not to exist nor even to be able not to existâ⬠.

To elaborate, each individual has a limitation to his imaginative powers as well as varied ability to understand complex matters. In that case, if the existence of God is derived from the ability of the mind, arenââ¬â¢t some individuals better endowed to grasp this supposed reality than others? What about people suffering from psychiatric disorders or mental retardation? Are they capable of conceiving God? If not, does that mean God doesnââ¬â¢t exist? The problem with Ontological Arguments arises because of their primacy to the subjective experiences of an individualââ¬â¢s mind. I also find Gauniloââ¬â¢s allegory of the ââ¬ËLost Islandââ¬â¢ to be a fitting rebuttal to Anselmââ¬â¢s proposition. Anselm of Canterbury was one of the early promoters of the Ontological Argument supporting the existence of God. He argues that God exists on the basis that ââ¬Ësomething-than-which-nothing-greater-can-be-thoughtââ¬â¢ should necessarily exist in reality.

The Secret Garden Essays - Literature, English-language Films
The Secret Garden Essays - Literature, English-language Films The Secret Garden The Secret Garden By Frances Hodgson Burnett The Secret Garden by Frances Hodgson Burnett takes place in a dreary Misselthwaite manor in England during the Victorian era. The protagonist is Mary Lennox a selfish and spoilt 11 year old. The other major characters are Master Colin Craven her sickly cousin, Dickon Sowerby the animal charmer, Master Archibald Craven her reclusive uncle, Martha Sowerby a hearty housekeeper, a dour gardener, a cheerful robin and the secret garden. The tone is melodramatic and is told in the third person omniscient. The message about life to be learned from the story is that its never too late to change, no matter how terrible, you can make the best of things. Face the problems instead of cowering from them because if your dont theyll never go away. Have a positive attitude, live life and share it with the people around. Alienating yourself is not the solution. Mary, Colin and Archibald Craven are examples of this. Mary didnt care for anything, she was so spoilt that nothing and no one meant anything to he; she was so used to everybody hating her. Colin is also spoilt and filled with ideas that hes going to die. Archibald is the coward that cant face reality or the hope for a better tomorrow. The one thing they all have in common is negatively, you get the sense that they would rather be dead and in reality its like they are because they dont care about anything. Mary is tossed around like a rag doll nobody wants; Colin is expecting to die and Master Craven runs from the possibilities of getting to know his son. In The Secret Garden there is person vs. society and person vs. her/himself. In person vs. society Mary is unloved by her parents and by most of those who she encounters. Her parents ignore her existence and leave her to the care of a hateful ayah. After her parents die she moves to live with her uncle and is greeted by Mrs. Medlock who finds her a disagreeable child. She and others dont give Mary a chance; they judge and sentence her. They do the same to Colin; they dont give him hopes of living and expect him to die soon. Person vs. her/himself is found when Mary, Colin and Master Craven have to find the courage to face the harsh world. They all fear this loneliness which they bring amongst themselves by withdrawing themselves from the world The climax in the story would have to be when Mary cant handle Colins tantrums and all his ranting and raving about the lump on his back thats going to kill him. She realizes that the way that Colin acts was the same way she used to be and she sets him straight. She doesnt give in to his hysterics and proves to him that the only lumps on his back are his bones. From that day on things change, Mary tells him about the garden and Colin gets a sudden interest in life. After that Mary takes him to the garden and this view on life changes, he says I shall live for ever- and ever- and ever. Its a combination of events with the help of different characters that bring this story to its conclusion. But it all starts with Marys arrival to the manor and her curiosity about the secret garden. Mary was used to being served and being alone, neglected by her parents she becomes bitter. Full of disagreeable thoughts about her dislikes and sour opinions of people and her determination not to be pleased by or interested in anything. There was no meaning in Marys life and thats why she was bitter, that changed when she moved to Misselthwaite where she discovers the secret garden with fantastic healing powers. The garden is walled up and has been locked up for years. With the gardeners apprentice, Dickon, Mary coaxes the garden back to life. The garden seems to have a wonderful, magical effect on all those who come into it, allowing Mary to help restore Colin to health and a reunion with his father. Its a story where faith restores health, flowers refresh the spirit and the

Learn About the Causes and Effects of Smog
Learn About the Causes and Effects of Smog Smog is a mixture of air pollutants- nitrogen oxidesà and volatile organic compounds- that combine with sunlight to formà ozone. Ozone can be beneficial or harmful, good or bad, depending on its location. Ozone in the stratosphere, high above the Earth, acts as a barrier that protects human health and the environment from excessive amounts of solar ultraviolet radiation. This is the good kind of ozone. On the other hand, ground-level ozone, trapped near the ground by heat inversions or other weather conditions, is what causes the respiratory distress and burning eyes associated with smog. How Did Smog Get Its Name? The term smog was first used in London during the early 1900s to describe the combination of smoke and fog that often blanketed the city. According to several sources, the term was first coined by Dr. Henry Antoine des Voeux in his paper, ââ¬Å"Fog and Smoke,â⬠which he presented at a meeting of the Public Health Congress in July 1905. The type of smog described by Dr. des Voeux was a combination of smoke and sulfur dioxide, which resulted from the heavy use ofà coal to heat homesà and businesses and to run factories in Victorian England. When we talk about smog today, weââ¬â¢re referring to a more complex mixture of various air pollutants- nitrogen oxides and other chemical compounds- that interact with sunlight to form ground-levelà ozoneà that hangs like a heavy haze over many cities in industrialized countries. What Causes Smog? Smog is produced by a set of complex photochemical reactions involvingà volatile organic compoundsà (VOCs),à nitrogen oxidesà and sunlight, which form ground-levelà ozone. Smog-forming pollutants come from many sources such as automobile exhaust, power plants, factories, and many consumer products, including paint, hairspray, charcoal starter fluid, chemical solvents, and even plastic popcorn packaging. In typical urban areas, at least half of the smog precursors come from cars, buses, trucks, and boats. Major smog occurrences often are linked to heavy motor vehicle traffic, high temperatures, sunshine, and calm winds. Weather and geography affect the location and severity of smog. Because temperature regulates the length of time it takes for smog to form, smog can occur more quickly and be more severe on a hot, sunny day. Whenà temperature inversionsà occur (that is, when warm air stays near the ground instead of rising) and the wind is calm, smog may remain trappedà over a city for days. As traffic and other sources add more pollutants to the air, theà smogà gets worse. This situation occurs frequently in Salt Lake City, Utah. Ironically, smog is often more severe farther away from the sources of pollution, because theà chemical reactionsà that cause smog take place in the atmosphere while pollutants are drifting on the wind. Where Does Smog Occur? Severe smog and ground-levelà ozoneà problems exist in many major cities around the world, from Mexico City to Beijing, and a recent, well-publicized event in Delhi, India. In the United States, smog affects much of California, from San Francisco to San Diego, the mid-Atlantic seaboard from Washington, DC, to southern Maine, and major cities in the South and Midwest. To varying degrees, the majority of U.S. cities with populations of 250,000 or more have experienced problems with smog and ground-level ozone. According to some studies, more than half of all U.S. residents live in areas where the smog is so bad that pollution levels routinely exceed safety standards set by the U.S. Environmental Protection Agency (EPA). What Are the Effects of Smog? Smog is made up of aà combination of air pollutantsà that can compromise human health, harm the environment, and even cause property damage. Smog can cause or aggravate health problems such as asthma, emphysema, chronic bronchitis and other respiratory problems as well as eye irritation and reduced resistance to colds and lung infections. Theà ozoneà in smog also inhibits plant growth and can cause widespread damage to crops and forests. Who Is Most at Risk From Smog? Anyone who engages in strenuous outdoor activity- from jogging to manual labor- may suffer smog-related health effects. Physical activity causes people to breathe faster and more deeply, exposing their lungs to moreà ozoneà and other pollutants. Four groups of people are particularly sensitive to ozone and other air pollutants in smog: Children- Active children run the highest risks from exposure to smog, as children spend a lot of time playing outside. As a group, children are also more prone to asthma- the most common chronic disease for children- and other respiratory ailments than adults.Adults who are active outdoors- Healthy adults of any age who exercise or work outdoors are considered at higher risk from smog.People with respiratory diseases- People with asthma or other chronic respiratory diseases are more sensitive and vulnerable to the effects of ozone. Typically, they will experience adverse effects sooner and at lower levels of exposure than those who are less sensitive.People with unusual susceptibility to ozone- Some otherwise healthy people are simply more sensitive to the pollutants in smog than other people and may experience more adverse health effects from exposure. Elderly people are often warned to stay indoors on heavy smog days. Elderly people are probably not at increased risk of adverse health effects from smog because of their age. Like any other adults, however, elderly people will be at higher risk from exposure to smog if they already suffer from respiratory diseases, are active outdoors, or are unusually susceptible to ozone. How Can You Recognize or Detect Smog Where You Live?à Generally speaking, you will know smog when you see it. Smog is a visible form of air pollution that often appears as a thick haze. Look toward the horizon during daylight hours, and you can see how much smog is in the air. High concentrations of nitrogen oxides will often give the air a brownish tint. In addition, most cities now measure the concentration of pollutants in the air and provide public reports- often published in newspapers and broadcast on local radio and television stations- when smog reaches potentially unsafe levels. The EPA has developed theà Air Quality Indexà (AQI) (formerly known as the Pollutant Standards Index) for reporting concentrations of ground-level ozone and other common air pollutants. Air quality is measured by a nationwide monitoring system that records concentrations of ground-levelà ozoneà and several other air pollutants at more than a thousand locations across the United States. The EPA then interprets that data according to the standard AQI index, which ranges from zero to 500. The higher the AQI value for a specific pollutant, the greater the danger to public health and the environment.

Adam Smith Wealth of Nations Essay Example | Topics and Well Written Essays - 250 words
Adam Smith Wealth of Nations - Essay Example Smith is actually considered to be the Father of Modern Economics.Adam Smith's ideas as reflected in his work are still relevant today. His concept of free-trade is still what majority of the world's economy is practicing. Free trade, according to Smith, is the ability of the economy to produce the sufficient amount of goods and provide different varieties with the guidance of what he calls "the invisible hand." If there is a shortage of a certain product, price tends to increase which, in turn, gives higher profit to the producers. This entices more producers to enter the market which leads to the increase in supply of the product and more competition among the producers. Given this condition, price naturally gets lower. Once the price gets too low that the producers would incur losses than profits, they will be out of business. Although this competition can be due to human's pursuit of self-interest, this benefits the society as a whole by keeping the prices of goods at a low level and, at the same time, having a variety of products and services.This idea is what happens in our modern economic society. Businesses get into the market because they can see a potential profitable market. And what prevents these businesses to monopolize in their field is the fact that there will be other businesses or individuals who would want to get into the same market and have a fair competition.

Critical analysis on an article Example | Topics and Well Written Essays - 250 words - 2
Critical analysis on an - Article Example Though this type of research is not new by any stretch of the imagination, the rigor and thorough nature of the datasets and graphs that the authors present help to engender a degree of well reasoned argument with which the reader can both understand as well as identify with. Although the weakness of the approach are not specifically enumerated upon, the authors begin the piece by discussing the ways in which the study of directional evolution risks over-simplifying the subject matter and ultimately reducing the research question to a form of ââ¬Å"what came first the chicken or the eggâ⬠. As a means of addressing such a threat, the piece seeks to lay out a firm and rigid framework of analysis which does not allow any form of broad generalizations on the subject matter (Whittall et al 706). As far as influencing the views of this particular student and providing a bigger picture conclusions, it can be definitively stated that the results that the piece has proven leave little if any doubt in the mind with regards to the clear and inarguable nature of directional evolution and the means through which it occurs. As a function of the bigger picture, this can be understood to re-affirm Darwinââ¬â¢s original theory and helps to shed a further light o n the ways in which individual species evolve, grow, and develop over

The Speckled Band Essay Example for Free
The Speckled Band Essay Looking at The Speckled Band and two other stories comment on the way Conan Doyle uses the character Watson I the stories. I have read three stories of Sherlock Holmes, written by the famous author, Sir Conan Doyle. The three stories I have looked at are The Speckled Band, The Engineers Thumb and The Man with the Twisted Lip. My main focus is on the character Dr Watson and how Doyle illustrates him. I know that Dr Watson is affectionate by the way he approaches people, I saw this in The Engineers Thumb, when he is caring for Mr Hatherlys severed thumb, and how he treated it. Also in The Man with the Twisted Lip he cares for Kate Whitney and gives her advice to do about Isa because he has not been home for two days. He makes her feel comfortable when advising her we know this because it says in the text have some wine or water, and sit here comfortably and tell us about it. Therefore it shows us that it is in his nature to deal with people that are upset, and he is very good at doing it. Again in the The Man with the Twisted Lip when Kate comes to him late at night, because she is upset and needs advice, in the text it quotes I want the Doctors advice and help this immediately tells me and the audience that people seek Watson for help. Quote from the text we soothed and comforted her, again it tells us that he is kind I friendly. Through this I kind of get the feeling that many people in the Sherlock Holmes stories people, made visits to Watson for advice, because he was a nice and comfortable man to talk to and didnt push you quick so he could see another client, and understood how the client must feel. He is very fond of Holmes and id a very good companion as he always does investigations with Holmes I refer to this in The Speckled Band when Holmes is at the end of bed and tells Watson about a client and a investigation they are going to have to look into an investigation and he replies I would not miss it for anything. This tells me that he will always be there for Holmes to help him out, in my words an acolyte. When you have a friend then you must have trust in the friend so Watson has a great level of trust in Holmes. Holmes is not the brightest person either as it is always Holmes that works out the investigation, as Holmes realised what the speckled band was in the The Speckled Band. He realised that it was a snake that was killing people, and it was one of the pets Dr Grimesby Roylott which he had brought over from India. Watson has no fear really either as he entered the room with the snake in which could kill people in a bite most people would fear to enter a room with something this deadly. Throughout the stories of Sherlock Holmes Watson appears to be the narrator, he tells the story as it goes along from what he sees of it and tells about his and Holmes investigations, but never works them out for himself, only when Holmes says the result of the investigation he realises. We know this by in The Man with the Twisted Lip he is saying what is going on We heard the door open this is just as the story goes and it tells us he is the narrator as when he speaks it is in speech marks. This tells us that Watson is telling the story for us, in other words the narrator. When Watson narrates though his voice is not impersonal to Holmes as he does have the greatest respect for him, we can tell this by when Holmes is at the end of his bed in The Speckled Band he narrates just a little resentment, for I was in myself in regular habits. This does not show hate to Holmes it just shows a bit of annoyance as he is at the end of the bed, when Watson is waking up in the morning, and Holmes is seeing him do habits which everybody does when they wake in the morning. I can tell through this that he does not seem too pleased about Holmes at the end of the bed, but still even though he is he shows a lot of respect to Holmes.

why i want to become a doctor Essay -- essays research papers
There is one Haitian proverb that has never lost its potency, despite the atmosphere of economic adversity, numerous civil wars, and political unrest: à ¡Ã °Piti, piti, wazo fe nich li.à ¡Ã ± Literally, the phrase means, à ¡Ã °Little by little, the bird builds its nestà ¡Ã ±; figuratively, it represents building oneà ¡Ã ¯s way, à ¡Ã °little by little, à ¡Ã ± toward oneà ¡Ã ¯s goals in life. To further understand the sayingà ¡Ã ¯s significance, we should first consider the nature of birds. From tailorbirds that suture leaves together to some hummingbirds and pee wee wrens that use lichen and spider webs to build their nests, we can see the resourcefulness birds demonstrate in obtaining nest-building materials. My life has been a similar process of building a metaphorical nest -- acquiring such qualities as compassion, dedication, and leadership through a variety of experiences to prepare for a successful career as a physician. As a bird builds through changing seasons, I too have prepared for the study of medicine through variously themed à ¡Ã °seasonsà ¡Ã ± in my life. During high school, for example, I focused my activities on serving the various communities of which I am a part. After joining Mt. Olivet SDA Church, I became involved with the community of Williamsville, New York -- participating in an anti-drug rally and health fair, leading local public speaking events, singing in church choirs at nursing homes, and visiting hospitalized church members. I was also a mentor and counselor for underprivileged children...

Spontaneous Generation and Cell Theory
Spontaneous Generation and Cell Theory 1. Tradition thought is very hard to overcome- even with solid evidence to support new ideas * Social pressure has effect on acceptance of scientific ideas and technological advancements * Science is a social/political enterprise * New ideas often met with resistance * Sometimes ostracisms, persecution, death * Microscope helped to overturn some strange ideas * Disease processes * ââ¬Å"spontaneous generationâ⬠Attitudes and skills of scientific inquiry (questioning, predicting, observing and recording) are required to provide unbiased and factual info * Investigations must follow ethical guidelines and results must be reproducible under controlled conditions * Example of way that science, technology and society are linked is found in development of the current understanding of the way living cells function * Microscope provided technology to explore the world of microscopic particles and organisms * Then possible to obtain evidence for or against generally accepted opinions or theories about living thingsSpontaneous Generation 2. Believed that life can emerge from non-living matter 3. A superstition- people unaware of microscopic forms of life * e. g. mice created from mixing wheat husks with sweaty undergarments * Maggots and flies emerge spontaneously from raw meat * Francesco Redi * Example of scientific method * Believed flies laid eggs on meat * Experiment to prove hypothesis Limited access to meat (air, no fresh air, flies, no flies) 4. Idea that life could emerge spontaneously from non-living matter = widely accepted from time of the Romans through to the 19th century * Even in time of Robert Hooke and Antoni van Leeuwenhoek * Believed that to produce mice, you put a sweaty underwear and husks of wheat in an open jar and after 21 days, the sweat and husks would combine and change the husks into mice 5. 668, Francesco Redi (Italian physician and poet) questioned belief that maggots appeared from raw meat * He believed that flies laid their eggs in the meat * Set up experiment to test his hypothesis * Set out flasks containing raw meat but some were sealed, some were covered in gauze and some were open to the air * Controlled the access of flies to the meat * Maggots were found only in the flasks that were open and accessible to flies to lay their eggs * Despite evidence, idea of spontaneous generation still thrived 6.John Needham (proving that living things could be produced from non-living matter) boiled chicken broth and put it in a flask and sealed it * Everyone accepted that boiling killed micro-organisms since boiling was a common method of removing substances that would make one ill * However, in his experiment, micro-organisms continued to appear * Suggested that there was a life force that produced spontaneous generation 7.Lazzaro Spallanzani (Italian priest) claimed that there were micro-organisms in the air that were responsible for the new growth * Re-did Needham's experiment but drew off the air in the flask, nothing grew in the remaining broth * Critics suggested that all Spallanzani had shown was that air was required for spontaneous generation to occur * Spontaneous generation theory continued to be accepted 8. 859, French Academy of Sciences announced a contest for the best experiment to prove or disprove spontaneous generation * Louis Pasteur used the work of Needham and Spallanzani with important change * Before boiling meat broth in flask, Pasteur heated the neck of the flask and bent it into an ââ¬Å"Sâ⬠shape * Air could reach the broth but micro-organisms and other particles would get caught in the S- bend * Nothing grew in this broth but if the flask were tipped so that the broth reached the S-bend in the neck, moulds would later appear 9.Pasteur controlled his experiment in that he used the same broth, same type of flasks and same light and temperature conditions * Controlled variables (conditions that are held constant throughout an e xperiment): broth type, flasks type, light, temperature * Manipulated ariable (condition deliberately changed in an experiment): access of dust to the flask * Responding variable (condition that changes in response to the manipulated variable in an experiment): ability to grow mould in the broth * Had experimental control, a part of the experiment which the manipulated variable is not changed in any way from its normal condition * Flask in which dust had normal access to the broth after boiling * Result: moulds occurred * Experiment treatment Prevent the access of dust to the broth, resulting in evidence of no growth of mould * To allow access of dust to the broth very briefly, resulting in evidence of mould growth * Strong evidence that says that spontaneous generation doesn't occur, but also that micro-organisms are found in the air * His work opened new doors to microbiology, immunology, biochemistry and gave credibility and new importance to the processes of conducting controlle d experiments, maintaining detailed records of observations, and connecting results to conclusionsThe Cell Theory 10. Importance of cell as the functional unit of life was recognized with the improvements in lens technology and increased number of observations made by scientists in several countries 11. 1833, Robert Brown identified an important cell structure, the nucleus, in study of orchids * Saw an opaque granular spot within the cell * Others had seen it too but he was the first to recognize at this cell structure must have something for cell function 12. 1838, M. J.Schleiden observed that all plants were composed of cells and he proposed that the nucleus was the structure responsible for the development of the remainder of the cell * Discussed his work with a friend (Theodor Schwann), who was studying animal physiology * Schwann believed that there must be similarities btwn plant and animal tissue * When Schwann searched for opaque spots in animal tissue, he found structures t hat resembled the cells that botanists were studying in plant tissue and the nucleus structure that Brown and Schleiden had identified 13. 839, Schleiden and Schwann proposed the cell theory as a result of observations of plant and animal specimens through the microscopes * All plants and animals were composed of cells and that the cell was the basic unit of all organisms 14. 1859, cell theory was further extended by Rudolf Virchow's statement that all cells arise only from pre-existing cells Cell Theory 15. All living things are made up of one of more cells and the materials produced by these cells 16. All life functions take place in cells, making them the smallest unit of life 17.All cells are produced from pre-existing cells through the process of cell division 18. Applies to all living things regardless of size, shape or number of cells involved * Subcellular particles (viruses and prions) fall into category that is neither living nor non-living although they may exhibit certai n characteristics of living cells 19. Evidence in support of cell theory came from Pasteur's experiment to investigate the concept of spontaneous generation in micro-organisms * Cell theory has become the cornerstone of the study of biology

Future of Pakistan
Future of Pakistan After a great struggle Muslims of the sub-continent succeeded to get a homeland where they could lead their lives according to their religion. On 14th august, 1947. Pakistan came into being. unto now Pakistan has made much progress in different fields. Although Pakistan has been In troubles from the very first day yet It has made much progress . Now Pakistan is the 6th atomic power in the world. Exploring current images of Pakistan's futures is the task for this essay. Based on a literature review ofPakistani magazines, newspapers and Journals as well as conversations with Pakistani scholars and interviews with members of the general public, we develop and evaluate five Images or scenarios of the future. This essay concludes with suggestions for designing alternative futures for Pakistan. Before we articulate these images of the future, let us first examine the ââ¬Å"futures approachâ⬠to the study of social reality. A futures view focuses primarily on tempor ality. Where are we going? What are the possibilities ahead? What strategies can we use to realize our goals?How can he Image of the future help us better understand and change today? who are the losers and winners In any particular articulation of time? The futures perspective Is initially similar to traditional political analysis in that it begins with an exploration of economic, International and social events and the choices made by actors that make these events possible. However, the futures view also attempts to place events and choices within an historical dimension; that is, the larger and deeper structures that make these discrete events intelligible, such as core-periphery. ban-rural, gender, caste, and macro patterns of social change. Also important in the futures view is the post-structural dimension; the larger meaning system or the epistemological ground plan of the real as embedded in language that constitutes events and structures. unfortunately, most efforts to unde rstand the future remain in the predictive mode. It Is often asked. what and when will a particular event occur and how can we profit or increase our power from a specific prediction? Economists and strategic analysts claim to excellent this task.Our efforts here-sensitive to the richness of reality and the need to decolonize the study of the future from narrow models of realityââ¬âis to explore images or scenarios of the future. Our task is not to predict and thereby make this essay political fodder for technocrats but to use the future to create real possibilities for change. We thus do not intend to give a familiar reading of Pakistan's future, as might be available In a five year plan, rather we enter Into a discussion of alternative futures, of the many choices ahead as contoured by the structure of istory and the modern boundaries of knowledge that frame our identity.In the images or scenarios that follow it should be remembered that these images are meant as tools for dis cussion and dialog; they are intended to clarify the futures ahead not to reify social reality. Our goal is Insight not prediction. As an Initial caveat, an important failing of this essay is that the textual sources and conversations were entirely in Englishââ¬âone might get different images with local Pakistani languages.By Zainabazharl 2 here they could lead their lives according to their religion. On 14th august, 1947, Pakistan came into being. Unto now Pakistan has made much progress in different fields.

assisted suicide or euthanasia essays
assisted suicide or euthanasia essays On July 26, 1997, the U.S. Supreme Court unanimously upheld decisions in New York and Washington State that criminalized assisted suicide. As of April 1999, physicians-assisted suicide is illegal in all but a couple of states. Over thirty states have established laws prohibiting assisted suicide, and of those who dont have statues, a number of them prohibit it through common law. In Michigan, Jack Kevorkian was initially charged with violating the state statue. He was charged with first-degree murder and delivering a controlled substance without a license. The assisted suicide charge was dropped, however, he was eventually convicted of second-degree murder and delivering a controlled substance without a license. Only one state, Oregon, has legalized assisted suicide. The Oregon law, which went into effect in October 1997, provides that a doctor may prescribe, but not administer, a lethal dose of medication to a patient who has less than six months to live. As of April 1999, 2 3 patients were given the drugs under the statue, and 15 of them used the drugs to commit suicide. A report released by the Oregon State Health Division found that the law was working well and had not been subject to abuse (REED A9). The word Euthanasia originated from the Greek language: eu means good and thanatos means death. The term euthanasia normally means that the person who wishes to commit suicide must initiate the act (WORLD BOOK). However, some people define euthanasia to include both voluntary and involuntary termination of life. Euthanasia has many meanings so it is important to differentiate among the vaguely related terms. These meanings of terms were cited from George Lundberg, M.D. in Views of Assisted suicide. Involuntary Euthanasia: This term is used by some to describe the killing of a person in opposition to their wishes. It is basically a form of murder and not a popular view among most people...

Aircraft Mechanics and Aircraft Inspectors
ww. ontario. ca/jobfutures à © Queenââ¬â¢s Printer for Ontario, 2009 Aircraft inspectors perform some or all of the following duties: â⬠¢ â⬠¢ â⬠¢ Inspect structural and mechanical systems of aircraft and certify that these systems meet Transport Canada and company standards of performance and safety; Inspect work of aircraft mechanics performing maintenance, repair and overhaul, or modification of aircraft and aircraft mechanical systems to ensure adherence to standards and procedures; Maintain detailed repair, inspection and certification records and reports. Operations, which are carried out mostly in hangars, expose workers to noise, vibration, liquids, fumes and other hazards requiring the use of safety equipment and clothing. A five-day, 40-hour workweek including shift work and overtime is normal. Education/Training Aircraft Maintenance Technician (AMT) A minimum of high school education as well as a community college certificate in aircraft maintenance is required. Most colleges are dual- accredited by both Transport Canada and Canadian Aviation Maintenance Council (CAMC), meaning that graduates get credit for the technical examination towards Aircraft Maintenance Engineer (AME) licensing and credit towards CAMC certification as an aircraft maintenance technician. Aircraft Structures Technician (AST) The minimum education level is high school plus a formal community college training program in aircraft structures. Most colleges are dual accredited by Transport Canada and CAMC meaning that graduates get credit for the technical examination toward Aircraft Maintenance Engineer (AME) licensing and credit toward CAMC certification as an aircraft maintenance technician. Several years of on the job training are then required to gain the necessary experience for CAMC certification and/or Transport Canada licensing. Experienced structures technicians with the equivalent of three years of documented experience can apply for an S category licence. Avionics Maintenance Technician (AvMT) There are basically two types of avionics maintenance technicians. One works at a bench/station in the electrical/avionics backshop where tests are conducted with specialized test equipment, and repairs are made or parts replaced. The second type of technician works in line maintenance and is a specialist in trouble shooting and solving avionics problems at the ââ¬Å"gateâ⬠. The minimum education level is high school with good physics and mathematics attributes. A structured community college certificate is also required or a recognized apprenticeship program. Most colleges are dual accredited by Transport Canada and CAMC meaning that graduates get credit for the technical examination towards Aircraft Maintenance Engineer (AME) licensing and credit towards CAMC certification as an aircraft maintenance technician. After two to three years experience, the technician can apply for CAMC certification. After the equivalent of four years experience, an avionics epair technician can apply for an E category licence. Aircraft Maintenance Engineer (AME) Page 2 www. ontario. ca/jobfutures After the equivalent of four years on the job experience, an aircraft maintenance technician can apply for an AME licence. An M1 or M2 license is awarded depending on the aircraft size for which the job experience applies. Military aircraft technicians can apply for a civil AME after civil aircraft experience is obtained. Aviation Maintenance Inspector Completion of secondary school is required. Candidates must have industry qualifications such as CAMC certification or CAMC-approved experience and training or an Aviation Maintenance Engineer (AME) licence. They must obtain an Aircraft Maintenance and Inspection Certificate for the types of aircraft and power plants upon which the candidate is normally employed. Supervisor experience is often desired by industry for this occupation. Candidates are required to have one yearââ¬â¢s experience performing aviation maintenance inspections on aeronautical product, and must possess formalized aviation-related trade qualifications such as an AME license or CAMC certification or a candidate must have five years of on-the-job experience performing aviation maintenance inspections in aeronautical products An apprenticeship training program exists in Ontario for aircraft maintenance engineer but certification is not a compulsory work requirement in the province. Entry to apprenticeship requires a job and usually completion of Grade 12. The apprentice applies directly to the employer, union or joint industry committee for an apprenticeship opening. Students who have completed Grade 10 have an opportunity to become registered apprentices while finishing high school under the Ontario Youth Apprenticeship Program. Alternatively, entry into apprenticeship can be pursued through pre-apprenticeship training. Employment Prospect Over the next five years: Average Opportunities for employment in this occupation are expected to be average over the period from 2009 to 2013. Despite the recent difficulties facing many North American airlines, the demand for more skilled workers, particularly in the maintenance sector is increasing. In addition, an aging workforce will create additional job opportunities through retirements. Industry growth and demographics will require that the aviation sector recruit and train sufficient new entrants with the appropriate skills in order to prevent self-induced shrinkage in that sector. According to the CAMC, unless significant and fundamental changes occur now, shortages of Aircraft Maintenance Engineers (AMEs) and non-AME technicians will be widespread across the maintenance sub-sector through to 2015. Employment prospects will also continue to be good for these workers since many students with the aptitude to work on planes are choosing instead to go to university or work in computer related fields. Aircraft Maintenance Technician (unlicensed) are expected to posses the skills and knowledge of a licensed AME (Aircraft Maintenance Engineer). Employers place considerable emphasis on attitude, teamwork skills and technical knowledge. Aircraft Structures Technician (unlicensed) will need to acquire experience in structures such as composite repairs in addition to aluminium sheet metal and steel as demand for lap joint repairs falls in newer aircrafts. Avionics Maintenance Technician (unlicensed) will need to obtain skills in line maintenance and troubleshooting as more elaborate electrical systems are installed on new aircrafts. Page 3 www. ontario. ca/jobfutures Aviation Maintenance Inspector will become the ââ¬Å"super AMEâ⬠possessing in-depth knowledge of all of an aircraftââ¬â¢s various systems. Aviation maintenance inspectors will be supported by a team of specialist system technicians.

Digital Radiography Research Paper Example | Topics and Well Written Essays - 750 words
Digital Radiography - Research Paper Example hich relies on a digital media to capture and present the pictures it takes, rather than the more classic use of photographic filmâ⬠(McGuigan, n.d.). There is not much difference between the examination styles of digital radiography and screen-film radiography from the patientââ¬â¢s perspective. The presence of a digital receptor and a computer system makes digital radiography different to screen-film radiography. Some of the main components of the digital radiography system include a digital image receptor, a digital image management and processing system, a display device, and data storage device. There are a number of advantages of digital radiography over screen-film radiography. Some of the key advantages of using digital radiography system include improved contrast, immediate observation of images, facility of magnifying the images, facility to transfer the images to other computer systems, real time interpretation of the images, better abnormality detection ability, reduced image processing time, and facility of storing images using computer technology. ââ¬Å"Pulling up specific stored radiographic images from a comput er database is easy because of the highly organized nature of computer file storageâ⬠(Christensen, 2004). One of the key advantages of digital radiography is that of its efficacy in contemporary screening practices. A faster and more accurate examination is possible through digital method of radiography, which not only results in the reduction of the test duration but also provides comfort to the patients due to reduced examination time. Denise and Farleigh (2005) states, ââ¬Å"One of the principal advantages of any digital imaging system is the separation of image acquisition, process and display, allowing optimization of each of these stepsâ⬠. Speed is one of the major advantages of digital radiography system. The radiologists can produce the images very quickly using digital technology as compared to screen-film radiography. Digital
