John Lockes Theory of Knowledge Essay - 1067 Words
John Locke was an empiricist who believed that people could acquire knowledge from experience. Ideas acted as raw materials and by knowing the relation of the ideas, we got knowledge. All ideas are based on experience but knowledge can also be justified by intuition and demonstration. By sensation and reflection, we get sensitive, intuitive and demonstrative knowledge with different degrees of certainty and ways of evidence. In investigating the two main sources of ideas of Locke, we then will explain the two kinds of knowledge which based on reasoning by using suitable examples. The existence of external objects by sensation will also be proved. At last, we will introduce the dream argumentsâ⬠¦show more contentâ⬠¦Sensation and reflection are the only origins that our ideas take their beginnings. Intuitive knowledge is of greatest certainty by immediate perception of the mind without others intervention. In intuitive knowledge, the mind understand or know something immediately without needing to think about it, learn it or discover it by using reason. The mind identifies the truth without having to prove or examine ideas. By direct reasoning, it perceives that human is different from a dog, a circle is not a triangle, three are more than two. The mind identifies the agreement or disagreement of two ideas by their own immediately, exclusive of othersââ¬â¢ interference. Intuitive knowledge is the clearest and of most certainty, with no double nor hesitation. It is irresistible and immediately perceived by the mind. The certainty of intuition is so great that one cannot conceive. As a result, a greater certainty is not needed. The existence of ourselves is also an intuitive knowledge. Our consciousness implies our existence. It is not capable or need any proof. This is be cause nothing can be more certain than our own existence. Demonstrative knowledge is the next degree of knowledge that something is proved and explained. The mind identifies the agreement or disagreement of ideas, but unlikeShow MoreRelatedJohn Lockes Theory of Knowledge Essay1563 Words à |à 7 PagesJohn Locke (1632-1704) was the first of the classical British empiricists. (Empiricists believed that all knowledge derives from experience. These philosophers were hostile to rationalistic metaphysics, particularly to its unbridled use of speculation, its grandiose claims, and its epistemology grounded in innate ideas) If Locke could account of all human knowledge without making reference to innate ideas, then his theory would be simpler, hence better, than that of Descartes.

Alzheimers Disease Essay - 1733 Words
Alzheimers Disease Alzheimerà ¡Ã ¦s disease is a slow, progressive, and degenerative disease of the brain. This disease is marked by a gradual loss of memory and other cognitive functions. quot;Alzheimers Disease is also known as the most common cause of dementia--a general term referring to the loss of memory and the ability to think, reason, function, and behave properlyquot; (Medina,1999). It primarily affects adults in their 60s or older and eventually destroys a persons ability to perform simple, routine tasks or even to care for themselves.

Researchers are learning about what happens to the brain as we grow old, what happens to brain cells in Alzheimers Disease, which genes are associated, and many other factors that may be significant. Some of the most promising Alzheimerà ¡Ã ¦s research is being conducted in the field of genetics to learn the role a family history of the disease has in its development. Scientists have learned that quot;people who are carriers of a specific version of the apolipoprotein E gene (apoE gene), found on chromosome 19, are several times more likely to develop Alzheimerà ¡Ã ¦s than carriers of other versions of the apoE gene. Nearly half of all late-onset Alzheimerà ¡Ã ¦s patients have the less common apoE4 version and research has shown that this gene plays a role in Alzheimerà ¡Ã ¦s diseasequot;(Cutler amp; Sramek, 1996).

Sonography Career free essay sample
The first time I started college I had a different career path. It was not after my pregnancies that I decided to make the change to sonography. I think sonography is a career that really fits my expectations, and to make sure I am in the right path I will research this career in depth. Tests and evaluations in sonography are in writing and practical. They are prepared to measure the studentââ¬â¢s understanding of the material, and the knowledge in manipulating the transducer (Craig 53). At the beginning I was curious about how the test would be. I now know the reading tests are normal types of tests: objective, which is cover multiple choices or true and false, and the subjective, which are the essays questions. I also found, I will have some tests on computer (Craig 46-47) which I think is a great idea because I will get accustomed to the way that certifying test are now presented, also it will help me to be successful in my career. The practical exams will help me to familiarize in working with patients on a day to day work habit, and the writing and computer exams will prepare me for my certifying examination post graduation. Sonography has different types of sonograms in which I can specialize. There are eight types of diagnostic ultrasounds specialties, but there are three which are the common practiced: abdominal, obstetric and gynecologic, and cardiac (Craig 152). This is great for me, because obstetric and gynecologic is the type of ultrasound I would like to specialize. Also, since this type of ultrasound is one of the most common I think it will be easier find a job in this field. Registration is very important in the sonography field. Graduates are encouraged to take their registry examinations as soon as possible after completion of their training (Craig 53). â⬠In my opinion this is great because the knowledge of the sonographer is tested again giving us the opportunities to have prepared sonographers in the health facilities. Since ââ¬Å"employers prefer candidates registered through the American Registry for Diagnostic Medical Sonography (Morsch)â⬠being registry is an open door for sonographers trying to get a job. American Registry for Diagnostic Medical Sonography (ARDMS) offers the opportunity to sonographers to earn three different types of credentials. The credentials are Registered Diagnostic Medical Sonographer, Registered Diagnostic Cardiac Sonographer, and Registered Vascular Technologist. In order to be award with one of them the graduate needs to pass two exams: one general and one specialty exam that depend on the credential wanted (ARDMS). This I think is a wonderful requisite because it elevates the prestige of sonographers. As more credentials I can get more knowledge I will have. Salary is another point in my research. ââ¬Å"In 2008, the starting salary for a diagnostic medical sonographer was $43,600 (Diagnostic Medical Sonography). Even though this is not the most important point for me I have to admit it is within the range I was expecting for salary. According to the Bureau of Labor Statistics the annual mean wage in Florida is $56,990 which breaks down in $27. 40 an hour (Bureau). This is better than the figures from 2008 and if salary follows this line by the time I graduate it should be even greater. The outlook of this job is great. ââ¬Å"Employment of diagnostic medical sonographers is expected to increase by about 18 percent through 2018-faster than average for all occupations (Bureau)â⬠. This is about 2. 25 percent per year. Sonograms will become the most popular tool in the medicine field to check the human body since is not harmful and very effectively. The truth is that ââ¬Å"sonography is in high demand trough out the country since the uses of sonography are expanded (Sonography). â⬠Another factor that will help on the growth of the sonography is the population who is aging. Older people needs more tests and Florida is one of the favorite states for retired people, so I would say that we will have a nice increase on the growth rate. Learn about searching jobs I think is important. After I graduate I would like to know the most important factors when looking for a job. As I found there are many tips for a successful job search. A resume accompanied of a personalized letter, always listen to the interviewer and answer the questions straight and precise, choose professional clothes for the interview day, negotiate the salary if it is no right for you, and always get the final offer in writing (Craig 213-216). Responsibilities are part of all jobs. Sonographers once they graduate start taking responsibilities which include preparing reports, organized daily work schedule, and report equipment failure(Craig 205). Searching this I notice that sonographers donââ¬â¢t only make reports and scans in fact I will do more than what I thought was my responsibilities. Sonography also has disadvantages. Musculoskeletal injury has been affecting sonographers for years. The amount of sonographers in the country is a small number compare to other professions in health, but the amount of injured sonographers is that big relative to the total number of sonographers that brought the attention of NIOSH. To protect sonographers from musculoskeletal pain NIOSH recommend a few safety measures for under graduates to avoid injuries (Musculoskeletal). This is really worry because I want a profession not an illness. I really think the programs should emphasize more on safety rules to avoid MSI from happen so frequently. I have learned plenty of information with my sonography research paper. Now I like even more my career. I believe I will have a great future if I keep going in this direction. Sonography is a very popular job, and learn the inside of the human body it is always amazing.

Acid Rain Essays (1840 words) - Inorganic Solvents, Acid Rain
Acid Rain annon INTRODUCTION: Acid rain is a great problem in our world. It causes fish and plants to die in our waters. As well it causes harm to our own race as well, because we eat these fish, drink this water and eat these plants. It is a problem that we must all face together and try to get rid of. However acid rain on it's own is not the biggest problem. It cause many other problems such as aluminum poisoning. Acid Rain is deadly. WHAT IS ACID RAIN? Acid rain is all the rain, snow, mist etc that falls from the sky onto our planet that contains an unnatural acidic. It is not to be confused with uncontaminated rain that falls, for that rain is naturally slightly acidic. It is caused by today's industry. When products are manufactured many chemicals are used to create it. However because of the difficulty and cost of properly disposing of these products they are often emitted into the atmosphere with little or no treatment. The term was first considered to be important about 20 years ago when scientists in Sweden and Norway first believed that acidic rain may be causing great ecological damage to the planet. The problem was that by the time that the scientist found the problem it was already very large. Detecting an acid lake is often quite difficult. A lake does not become acid over night. It happens over a period of many years, some times decades. The changes are usually to gradual for them to be noticed early. At the beginning of the 20th century most rivers/lakes like the river Tovdal in Norway had not yet begun to die. However by 1926 local inspectors were noticing that many of the lakes were beginning to show signs of death. Fish were found dead along the banks of many rivers. As the winters ice began to melt off more and more hundreds upon hundreds more dead fish (trout in particular) were being found. It was at this time that scientist began to search for the reason. As the scientists continued to work they found many piles of dead fish, up to 5000 in one pile, further up the river. Divers were sent in to examine the bottom of the rivers. What they found were many more dead fish. Many live and dead specimens were taken back to labs across Norway. When the live specimens were examined they were found to have very little sodium in their blood. This is typical a typical symptom of acid poisoning. The acid had entered the gills of the fish and poisoned them so that they were unable to extract salt from the water to maintain their bodies sodium levels. Many scientist said that this acid poising was due to the fact that it was just after the winter and that all the snow and ice was running down into the streams and lakes. They believed that the snow had been exposed to many natural phenomena that gave the snow it's high acid content. Other scientists were not sure that this theory was correct because at the time that the snow was added to the lakes and streams the Ph levels would change from around 5.2 to 4.6. They believed that such a high jump could not be attributed to natural causes. They believed that it was due to air pollution. They were right. Since the beginning of the Industrial revolution in England pollution had been affecting all the trees,soil and rivers in Europe and North America. However until recently the loses of fish was contained to the southern parts of Europe. Because of the constant onslaught of acid rain lakes and rivers began to lose their ability to counter act their affects. Much of the alkaline elements; such as calcium and limestone; in the soil had been washed away. It is these lakes that we must be worried about for they will soon become extinct. A fact that may please fishermen is that in lakes/rivers they tend to catch older and larger fish. This may please them in the short run however they will soon have to change lakes for the fish supply will die quickly in these lakes. The problem is that acid causes difficulties the fish's reproductive system. Often fish born in acid lakes do not survive for they are born with birth defects such as twisted and deformed spinal columns. This is a sign that they are unable to extract enough calcium from the water to fully develop their bone. These young soon

Pan the Goat-Footed Greek God
Pan the Goat-Footed Greek God Pan- or Faunus in Roman mythology- is the noisy goat-footed god of the Greeks. He looks after shepherds and woods, is a capable musician, and invented the instrument named after him- panpipes. He leads the nymphs in dances and stirs up panic. He is worshiped in Arcadia and is associated with sexuality. Pan's Family of Origin Pan was born in Arcadia. There are various versions of the birth of Pan. In one, his parents are Zeus and Hybris. In another, the most common version, his father is Hermes; his mother, a nymph. In another version of his birth, Pans parents are Penelope, wife of Odysseus and her mate, Hermes or, possibly, Apollo. In the bucolic Greek poet of the third century B.C. Theocritus, Odysseus is his father. Attributes of Pan The attributes or symbols associated with Pan are woods, pastures, and the syrinx- a flute. He is depicted with goats feet and two horns and wearing a lynx-pelt. In the Pan painters vase, a goat-headed and tailed young Pan pursues a youth. Pan's Death In Plutarchs Moralia, he reports a rumor about the death of Pan, who as a god, couldnt die, at least in principle. Sources Ancient sources for Pan include Apollodorus, Cicero, Euripides, Herodotus, Hyginus, Nonnius, Ovid, Pausanias, Pindar, Plato, Statius, and Theocritus. Timothy Gantz Early Greek Myths itemizes many details about the Pan traditions.
