.... from the world, sort of like they are in their own dream world, which is what separates them from mentally retarded people. They don't seem aware that people are around them, including family members. Another thing that separates them from the mentally retarded is their display of strange postures, manners, habits, and compulsions. They might display rocking, hand flapping, strange food preferences, no eye contact, head banging, an insensitivity to pain, and other dangerous behavior. They are also often infatuated with inanimate objects. About 50 % of all autistic individuals are mute, or only speak once or twice in their entire life s .....

.... activities, and sometimes it is very much suggested. A person should get a physical exam done to check their blood pressure, cholesterol, and weight to make sure the exercises they are going to begin are appropriate for their fitness level. Once a person is cleared to exercise, they should always remember to stretch and warm up before doing the activity. Like any automobile, a person also needs to warm up their body before being used. One of the best ways to do this is to just do a light jog and then stretch. This way the muscles are warmed up a little bit and the person is not stretching cold muscles which could cause an injury. .....

.... in infant mental development and adverse behavioral problems in children such as attention disorder. Nicotine crosses the human placenta and has direct effects on the developing fetus. Pre-clinical studies suggest that maternal smoking during pregnancy produces changes on the offspring's neural functioning, including reductions in uptake of serotonin, alterations in dopaminergic systems, alterations in peripheral and central noradrenergic neurons, and changes in DNA and RNA synthesis in the brain (9). Children prenatally exposed to nicotine consistently score lower in the two subcategories of expressive language and conceptual compre .....

.... proud of themselves. My great-grandmother was the type of person to bring out the best in everyone. As a child, I needed that because my home had its ups and downs. My parents were separated and I had been living with my mother. She was a young parent and did things that most mother did not. For instance, as a child she would leave me alone and sometimes physically abuse me. Therefore, I sometimes had a hard time understanding why she treated me so differently. On the other hand, I always received my explanations from my great-grandmother whom I called “ Mema�. I am not the only individual who considered her to be this type of .....

.... affects mostly upper & middle class teenage girls in the western world. This disease is both physically and psychologically damaging to these girls. For these girls, thinness and self-appearance is what they revolve their lives around. Studies conclude that people in professions where physical appearance is of extreme importance are more likely to develop an eating disorder. In the Western world, over the past two decades eating disorders have increased substantially. People believe that this increase in eating disorders is due to the fashion industry. The fashionable female figure of today has become thinner and more tubular (Szmulk .....

.... and based on instinct. To compliment this name the stimulus is known as the unconditioned stimulus (Myers 260). With Pavlov's new observations a new set of stimulus and response was found. This new set is known as the conditioned stimulus and the conditioned response. What is meant by conditioned response here is that the response was learned. The stimulus begins as neutral and causes no conditioned response. However, if the neutral stimulus can be associated with another stimulus, then it becomes a conditioned stimulus. Classical conditioning can be exemplified in the home, school, and school. In the home a child could smell .....

.... E, gene located on Chromosome 19. APOE, which encodes a protein that helps transport cholesterol in the body and also is involved in nerve cell repair, comes in three alleles, e2, e3, and e4. Those with one or two e4 alleles are deemed at higher risk of Alzheimer's disease, although those who possess APOE-e4 are not guaranteed to develop the disease. APOE-e4 may simply be unable to efficiently repair nerve cells. The presence of e4 does not signify if person will develop Alzheimer's; instead, it signifies when he or she will get it. Recent studies suggest that Alzheimer's may be affected by an interaction between APOE and the newly disco .....

.... of life, and can be very useful in every area of life. Science develops theories based on what is observed. It examines each theory with rigorous and scrupulous tests to see if it describes reality. The scientific method works well in observing and recording physical data and in reaching conclusions which either confirm or nullify a theory. During the mid-19th century, scholars (although at that time probably termed philosophers) wanted to study human nature with the aim of applying the scientific method to observe, record, and treat human behavior that was deemed as unnatural. They believed that if people could be studied in a scienti .....

.... realistic view, one should be monogamous and always use condoms. It has been researched that the use of condoms lowers the risk of becoming HIV infected by 90%. Although this protection is not 100% it is the only way that actually helps prevent you from getting the virus. I think that society should make condoms more accessible to young people, I believe they should have condom machines in girl and guys school bathrooms. I also feel that they should be distributed in school social events such as dances or proms, when it is most likely that they will be having sex. Giving youth condoms is not encouraging sex, in my opinion yet it is ed .....

.... painful disorder is the most common orthopedic disease in large and giant-breed dogs (Smith,1997). In order to fully understand this disease, you must understand the canine hip. The normal canine hip is a ball and socket joint consisting of the acetabulum and femur (Minnier, 1996). The acetabulum and femur provide for a tight fit and allow pain free movement. In a dog with CHD, the fit between the acetabulum and femur is loose causing friction between the two bones. This is manifested by varying degrees of laxity of the muscles and ligaments around the hip joint along with instability and malformation of the joint components (Anonymous, 1 .....
