  • Substance Abuse And Chemical Dependency - 636 words
    Substance abuse is the improper use of chemicals that can alter the way ones mind and body functions (TCC). In most cases, these chemicals would be referred to as a drug. Substance abuse can and may lead to chemical dependency or addiction. Dependence is the development of tolerance to chemicals which leads to symptoms of withdrawal. Substance abuse is a process that reflects a complicated interaction between the individual, the abused substance, and society (wikipedia.org). The leading cause of substance abuse or dependency is drug use in general. If you were to ask a drug user to tell you why they used drugs, they would most likely tell you that they use them to make themselves feel good. ...

  • Parsimony The Fourth Substance - 1,637 words
    ter> Sam Vaknin's Psychology, Philosophy, Economics and Foreign Affairs Web Sites Occasionalism is a variation upon Cartesian metaphysics. The latter is the most notorious case of dualism (mind and body, for instance). The mind is a mental substance. The body a material substance. What permits the complex interactions which happen between these two disparate substances? The unextended mind and the extended body surely cannot interact without a mediating agency, God. The appearance is that of direct interaction but this is an illusion maintained by Him. He moves the body when the mind is willing and places ideas in the mind when the body comes across other bodies. Descartes postulated that ...

  • Parsimony The Fourth Substance - 1,621 words
    ... f Quantum Mechanics is an important member of this species. The law of parsimony must apply both to the theory entities AND to observable results, both part of a coherent, internally and externally consistent, logical (in short : scientific) theory. It is divergent-convergent : it diverges from strict correspondence to reality while theorizing, only to converge with it when testing the predictions yielded by the theory. Quarks may or may not exist but their effects do, and these effects are observable. A law of parsimony has to be invariant under all transformations and permutations of the theory entities. It is almost tempting to say that it should demand symmetry had this not been me ...

  • Should Marijuana Remain An Illegal Substance - 1,899 words
    Marijuana has become a more and more acceptable drug over the past few years despite its many side effects, not only on the user, but also on society as a whole. Due to these side effects on society and the marijuana user, it would be in the best interest of everyone that marijuana remains an illegal substance. On one side of the issue you have marijuana users saying that it is their choice on whether or not they should be allowed to smoke marijuana. The question we have to ask ourselves is, are individual freedoms so important that we are willing to allow these individual freedoms to continue without consequence, even if their actions are harmful. The purpose of this essay will be to put fo ...

  • Signifance Of Anthropology And Archaeology - 1,521 words
    Anthropologists and Archaeologists Anthropologists and archaeologists have influenced our lives in so many ways. They have taken us back to our most humble beginnings. They have given us an awareness of just how far we have come through the centuries. Archaeology is the investigating of life by unearthing and interpreting the objects left behind by earlier peoples and cultures, dating back to prehistoric times. Anthropology is the scientific study of hominids, their physical features, development, and behavior. Anthropology is broken into two parts: physical and sociocultural. Physical is concerned with human evolution and biology and the study of primates. Sociocultural anthropology investi ...

  • None Provided - 5,836 words
    When we discuss our brain, we usually focus on the brains ability to think. That task alone is extremely complex and involved, but the brain also has many other tasks. Most of the time the brain is on autopilot, meaning that most of the activities preformed are just automatic. Our five senses; sight, sound, touch, taste, and smell, are automatically preformed in our brains. We don't have to think about how something sounds, we just hear it and we then interpret that sound. The largest area of our brain is the area that is set aside for vision, it is located in the occipital lobe. Dr. Gerard Guarniero has been blind since birth, a defect in which he has never been able to fix. Recently, he ha ...

  • Hypoglycemia - 1,438 words
    About four years ago we started to notice that my dad was having problems sleeping, he was very moody, and he started getting headaches a lot. After it got to a point where my dad was feeling bad every day we all started to worry. So as any normal person would do, my dad went to the hospital to have it checked out. The doctor found that my dad had developed a disease called hypoglycemia. At first this was very hard for my dad to handle because to subdue the symptoms of his disease he had to drastically change his diet. After doing a lot of research my mom had come up with a good diet for my dad, one that would help him to deal with his hypoglycemia. Now, what once was a major health problem ...

  • Holesterol - 1,541 words
    For years, cholesterol has been a major concern for millions of people around the world. This fear of cholesterol has led to many consultations with specialists like physicians and nutritionists. It seems that there is a great misconception about this molecule. A majority of the population is conscious of the harm that it can cause, but they are not aware that it has pertinent values to our body. There are two major forms that cholesterol comes in: 1) low density lipoprotein, which is generally considered "bad" cholesterol and 2) high density lipoprotein, which is known as "good" cholesterol. Although given these names, there is nothing inherently good or bad about them. This research will c ...

  • Colonialism - 1,934 words
    Colonialism has often spread to areas where it is economically valuable for the colonizer to develop. South America was one of these places. First came the Spanish for gold, then for rubber. As colonization took place two cultures met, thinking they were opposites, but in reality they were very much connected to one another, their histories were now tied together. In considering the question of how Indians have developed their healing practices and spiritual beliefs as a reaction to colonization, there are a number of areas we must explore. First, we will discuss how Indian and white cultures have integrated one another to the point where certain beliefs coexist or blend together. Secondly, ...

  • Caries - 2,372 words
    ... d warming of climate where there is an increase in the growth of plant material and plant foods. This change would have promoted a growth in subsistence farming, at the very least. This would have increased the amount of plant carbohydrates and thus there was an increase in the occurrence in evidence of caries. Again in the Mesolithic there is further warming in the surrounding climate to the point where an even greater amount of plant food harvest is attainable for human consumption. Frayer found that for the Mesolithic, there was a negative correlation between rates of caries and latitude. This was the case where skeletal assemblages from northern sites continually show a decrease in c ...

  • City - 1,332 words
    Cities exist for many reasons and the diversity of urban form and function can be traced to the complex roles that cities perform. Cities serve as centers of storage, commerce, and industry. The agricultural surplus from the surrounding country hinterland is processed and distributed within the city. Urban areas have also developed around marketplaces, where imported goods from distant places could be exchanged for the local products. Throughout history, cities have been founded at the intersections of transportation routes, or at points where market goods must shift from one mode of transportation to another such as river or ocean ports as well as railways. Cities are also sites of enormous ...

  • Manets A Bar At The Folies Bergere - 1,248 words
    Manet's painting, A Bar at the Folies-Bergre, was an integral factor in the rise of a new era in art; through the emergence of a contemporary Parisian city, Modern art began to flourish during the late 1800's. Being a painting of extreme complexity and ambiguity, many art critics have commented on the formal aspects of the painting, as well as the social reactions to this specific, and novel form of art. The purpose and meaning of the mirror behind the lady and the disparity of reality versus reflections, pose immense controversy and are discussed in Robert Herbert's essay, Impressionism: Art, Leisure, & Parisian Society, Bradford R. Collins, Twelve Views Of Manet's Bar, Jack Flam's "Looking ...

Escher demonstrated and understanding of differential special perceptions that were designed by considering the spatial circumstances within which elements of nature come into correlation and underscoring an artistic depiction based on these elements (Doornek 25). Two of Eschers more popular works, Day and Night and Three Spheres II are both artistic creations the underscore this defining focus on form over substance (Doornek 25). They also demonstrate the process by which Escher extends mathematics and scientific concepts into his artistry, and underscore the emergence as a reflection of his understanding of nature and of other cultures. Perhaps the most ...

  • Imagery In The Fall Of The House - 792 words
    Imagery of the Supernatural in "The Fall of the House of Usher" Edgar Allan Poe's writings are known for their macabre subject matter. In "The Fall of the House of Usher", Poe uses the life-like characteristics of an otherwise decaying house as a device for giving the house a supernatural atmosphere. Frank N. Magill explains this concept best when he writes, "Usher feels that it is the form and substance of his family mansion that affects his morale. He believes that, as a result of the arrangement of the stones, the house has taken on life" (1645). From the very beginning of the story, the reader can tell that there is something unusual and almost supernatural about the structure. As the na ...

Clearly, the injustice done by the simple misnaming of someone is unbelievable. After witnessing all of these names which bare no true meaning, as well as possibly degrade a person's character, Marlow understands that he can not continue in his former ways of mindlessly giving random names to something in fear of diminishing the essence of the recipient. As a result, Marlow finds himself unable to label something for what it is. While under attack, Marlow reefers to the arrows being shot in his direction as "sticks, little sticks", and a ...
