  • Abstract - 316 words
    ABSTRACT INTRODUCTION: The development of patient classification systems (PCS) in fields other than acute medicine raises the question if the principle of using existing data (i.e. diagnoses; procedures where available) is sufficent to describe the products of hospital care. METHODS/MATERIAL: The essence of a PCS (type "iso-cost") is to estimate costs of treatment needed in a defined setting by means of a description of the patient status (conditions) and the treatment goals. Two hypotheses guided our research into PCS development: (1) The description of patient status and treatment goals has to include multiple aspects which ideally are coded by using scales to show changes during the cours ...

Cellular Aging In 1961, a discovery made by Leonard Hayflick showed that normal, diploid cells from such continually Areplaced@ parts of the body as skin, lungs, and bone marrow, divide a limited number of times. Although the cells stop dividing at the point just before DNA synthesis, they do not die. The longer-lived the species, the more divisions the cells undergo. As the age of an individual increases, the number of potential divisions decreases (Ricklefs and Finch, 1995, 29). This discovery was found using fibroblasts, or cells found in the c ...

  • Aids And Std Education - 1,602 words
    ... Sexually Transmitted Diseases Sexually transmitted diseases are a major health concern for our country. With the spread of AIDS among so many people, both gay and heterosexual, it is important that we understand how these diseases spread and what we can do to prevent them. During the 1980s, human immunodeficiency virus (HIV) infection, the cause of AIDS, emerged as a leading cause of death in the United.States). In 1993, HIV infection became the most common cause of death among persons aged 25-44 years.(Center for Disease Control) Studies have shown a need for educational interventions and future in-depth studies of college students. An example is a study which showed that a group of ...

  • Albert Bandura - 1,049 words
    Albert Bandura Albert Bandura was born on December 4, 1925 in the small farming community of Mundare, Canada. He was educated in a small school with minimal resources, yet a remarkable success rate. He received his bachelors degree in Psychology from the University of British Colombia in 1949. Bandura went on to the University of Iowa, where he received his Ph.D. in 1952. It was there that he came under the influence of the behaviorist tradition and learning theory. He has since developed his social learning or cognitive theory and his ideas of observational learning and modeling, for which he made a place for himself in the history of Psychology. Yet his theory is still related to behaviori ...

  • Authorship Theory - 1,081 words
    Authorship Theory For a host of persuasive but commonly disregarded reasons, the Earl of Oxford has quietly become by far the most compelling man to be found behind the mask of Shake-speare. As Orson Welles put it in 1954, I think Oxford wrote Shakespeare. If you don't agree, there are some awful funny coincidences incidences to explain away. Some of these coincidences are obscure, others are hard to overlook. A 1578 Latin encomium to Oxford, for example, contains some highly suggestive praise: Pallas lies concealed in thy right hand, it says. Thine eyes flash fire; Thy countenance shakes spears. Elizabethans knew that Pallas Athena was known by the sobriquet the spear-shaker. The hyphen in ...

Genetics The most popular genetic theory, the Error Theory, assumes that aging is the result of the accumulation of random genetic damage, or from small errors in the flow of genetic information. The damage or errors would reduce or prevent proper cell function. Cellular The best known theory of aging in cellular research is called the Hayflick Effect, which is named after the American microbiologist ...

Just inside that circle of sarsens is a circle of bluestones, smaller stones which are usually not too much more than 6 feet tall. Inside of the bluestone circle is the trilithon horseshoe, or a horseshoe-shaped setting of sarsens in trilithons, or two sarsens standing next to each other with one lintel across the top. The open end of the horseshoe faces the northeast. Inside the trilithon horseshoe is a bluestone horseshoe. Inside the bluestone horseshoe, somewhat towards the center, is the altar stone, which might not have been used for that purpose. At the entrance to ...

After several questions regarding what the disease actually does to the body, I realized that this woman was unsure, and more interested in giving me a course in sexual intercourse rather than my health. Also she asked me about my relationships with friends and family that were non- physical in anyway. I was told that It was a potentially dangerous factor that I had a brother (whom I havent resided with for quit some years) that ...

    ... inclination i of the system, and several important things can be calculated. The mass function f(M) = M2^3 sin i / (M1 +M2)^2 gives a relation between the masses of the two bodies, and the semi-major axis a1=AM2/(M1+M2)^2 sin i (where A is the separation of the centers of mass) gives the size of the orbit, which can also be related to the rotational velocities of the stars. A spectroscopic binary with no visible companion would be a candidate for a black hole, and if the dim star's mass is determined to be greater than that of the visible star, it would be a promising candidate. However, this method consists of many uncertainties. Although there were no hard cases for black holes any sci ...

  • California, Gurse Books, 1983 - 1,203 words
    California, Gurse Books, 1983 The book I read was about the hard difficult task of overcoming this terrible eating disorder known as Bulimia. It is a secret addiction that dominates thoughts, severely undercuts self esteem, and threatens lives. Bulimia is a food obsession characterized by repeated overeating binges followed by purges of forced vomiting, prolonged fasting, and/or abusive laxatives, enemas and diuretics. A typical binge/purge cycle, who and why people become involved with bulimia, and the medical complications of bulimia, are all amazing factors that we should be able to recognize this deadly disease by, enabling us to suggest treatment. What is a typical binge? "Typical" depe ...

  • Charles Darwin - 1,851 words
    Charles Darwin Charles Robert Darwin was a man of many hats. He was a friend, colleague, son, father, husband; but above all, he was a naturalist. Through his dedication and perseverance did he manage to, in less than a generation, establish the theory of evolution as a fact in peoples' minds. In fact, [t]oday it is almost impossible for us to return, even momentarily, to the pre-Darwinian atmosphere and attitude (West 323). Darwin formed the basis of his theory during the voyage of the H.M.S. Beagle, on which vessel he was posted as it travelled around the globe. During that five-year span, this young man saw foliage, creatures, cultures that he had never known first-hand before. He was exp ...

  • Child Development - 623 words
    Child Development Chapter 9: Developmental Psychology I Teratogens are any medication, chemical, infectious disease or environmental factors that interfere with the normal development of a fetus that can result in a loss of pregnancy, birth defect, or a pregnancy complication. A wide variety of factors include: drugs, alcohol, and viruses. Through techniques of ultra sound and amniocentesis, one can determine the health of the fetus and determine whether terotagens have had any effect. Ultra sound involves directing high-pitched sound waves toward the fetus. A computer converts the waves into a sonogram (outline image of the fetus, uterus, placenta). Amniocentesis is the withdrawal and analy ...

  • Children's Psychological Adjustment To Entry Into Kindergarten - 1,388 words
    Children'S Psychological Adjustment To Entry Into Kindergarten Michael Burkhardt Page 2 From an ecological perspective, early childhood development occurs within the multiple contexts of the home, the school, and the neighborhood, and aspects of these environments can contribute to the development of adjustment problems (Bronfenbrenner, 1979). A child's psychological adjustment to entry into school for the first time can have a significant impact on the level of success achieved later in life. Children rated higher in school adjustment by their elementary school teachers, as a result of improved cognitive development, showed positive attitudes toward school resulting in better school perform ...

  • Christian Waugh - 728 words
    Christian Waugh The Better Half It was a great relief for me to read Aristophanes' speech in Plato's Symposium, since, as far as I'm concerned it is definitely the best speech in the book. It encompasses many aspects of love with which I readily agree, and readily embrace myself. The other speeches are good and well thought out, but they involve a variety of the aspects of love which appear to be unrelated. Aristophanes' speech presents a simple and effective solution for the problems that many of us, both ancient and modern, experience. The idea that love isn't something we can control, yet attempt to manipulate anyway, is explained in his speech. He definitely has a close, intimate touch w ...

  • Cognition - 396 words
    Cognition What are some other key biases that influence judgment? Judgment seems to be influenced by a variety of things each have their own implication on judgment. Overconfidence serves as a bias on judgment. Fischhoff, Slovic, and Lichtenstein, in 1997, tested this idea. The participants were given the question "Absinthe is a: A) liquer or B) a precious stone." The subjects were to choose the correct answer, and state the probability of being correct. It was found that when the subjects were 100 percent confident in their answers, they were only correct 80 percent of the time. This provides evidence that there is in fact, a dissociation between knowledge and awareness. Another bias that i ...

  • Communication - 1,424 words
    Communication Question 1 Option A Communication between two people sometimes is misinterpreted. One aspect of communication that makes it easy to distort the message being sent to a person is the use of nonverbal codes. Nonverbal codes are codes of communication consisting of symbols that are not words including nonword vocalizations.(P/N 73) The two categories I choose for this test are kinesics and paralinguistic features. Kinesics is the posture, movement, gestures, and facial expressions that are used to send a message. (P/N 73) One example of this is giving the finger to another person, which is showing only your middle finger to someone. This is socially accepted within the group of fr ...

  • Corporate Downsizing - 1,219 words
    Corporate Downsizing Introduction The U.S. economy was at the height of economic expansion, stocks were near all time highs, corporate profits were strong, and the unemployment rate was at its lowest in two decades. At the same time, the major corporations in the United States were firing workers by the hundreds of thousands, and job insecurity had risen to an extremely high level. What was also ironic was the fact that the corporations who were initiating the downsizings were considered to be some of the strongest and most profitable in the country. Although these events seem to be inconsistent, this is what has happened throughout the decade of the 1990's. Traditionally, downsizing was a d ...
