  • Experimental Ablation - 246 words
    Experimental Ablation Experimental ablation is one of the most common research methods. It consists of removal or destruction of part of the brain of an experimental animal for the purpose of studying the functions of that region of the brain. Most often tissue is destroyed rather than removed. The animal's behavior is then observed to determine what part of the body is controlled by that particular region of the brain. The technique is also referred to as lesion studies. The rationale behind such a procedure is that after a brain lesion occurs, if an animal can no longer perform a particular function which was previously performable, then an inference can be made that the area of the brain ...

  • A Personal Information - 1,287 words
    A. Personal Information Arthur Kornberg (1918-), American biochemist and physician, claims he has never met "a dull enzyme." He has devoted his life to pursuing and purifying these critical protein molecules. His love of science did not spring from a family history rooted in science. He was born on March 3rd, 1918, the son of a sewing machine operator in the sweatshops of the Lower East Side of New York City. His parents, Joseph Aaron Kornberg and Lena Rachel Katz, were immigrant Jews who made great sacrifices to ensure the safety of their family. They had fled Poland, for if they had stayed, they would have been murdered in a German concentration camp. His grandfather had abandoned the pate ...

  • Abstract - 925 words
    Abstract The experiment involved constructing a microphone from the materials given to us. Our group was supposed to make as sensitive microphone as possible. This laboratory was also intended to introduce the concept of sensor materials which can be made to act as electric sense organs. Our group has lost the competition, but even so by the end of the lab we understood how the microphone works and was able to construct it and test it using the Lab VIEW program. Introduction A real microphone consists of a diaphragm that is connected to a magnet. Sound waves vibrate the diaphragm and move the magnet in and out. The magnet is inside a coil of wire. When the magnet moves inside a coil of wire ...

  • Academic Effects - 950 words
    Academic Effects In the spring of 1997, Lisa Sharon Cushing and Craig H. Kennedy conducted an experiment to study the academic effects of providing peer support in general education classrooms on students without disabilities. In other words, students were paired with other students and their behavior observed. The study was undertaken to better understand the effects of peer support stratigies of participating students. Three non-disabled students were observed and a baseline measure of academic engagement was taken. Each student was paired to be a peer supporter with a disabled student and that level of behavior was observed. The experimental question states: Does serving as a peer support ...

  • Adult Illiteracy - 3,413 words
    Adult Illiteracy Learning to read is like learning to drive a car. You take lessons and learn the mechanics and the rules of the road. After a few weeks you have learned how to drive, how to stop, how to shift gears, how to park, and how to signal. You have also learned to stop at a red light and understand road signs. When you are ready, you take a road test, and if you pass, you can drive. Phonics-first works the same way. The child learns the mechanics of reading, and when he's through, he can read. Look and say works differently. The child is taught to read before he has learned the mechanics the sounds of the letters. It is like learning to drive by starting your car and driving ahead. ...

    ... e air over the wings creating lift. This initial force is usually found in the form of a propeller or a jet engine. An exception to those forms of thrust is a glider. A glider still needs an initial force to begin flight, which is usually found in a tow plane. The most commonly used thrust mechanism is a propeller. The propeller will continue to be the most commonly used because of its effectiveness and cheapness. Due to the jet engines high cost and high speeds it will remain primarily a military aircraft power plant. The physics of thrust used in aircraft is semi-complicated. Firstly, in the case of the propeller the propeller must be large enough to displace or pull enough air to keep ...

How can we help ourselves and others to understand what aggression is? First off, we need to define aggression, tell it's causes and effects and determine the best way to deal with it. For example, aggression can be positive or negative, accidental or intended and physical or mental. Aggression is a continuing behavior in our world today and I feel that it is very important that we try to start controlling it now. Aggression 3 Aggression is a crit ...

  • Aggression Biological Theory Vs Behaviorist Theory - 1,254 words
    Aggression - Biological Theory vs Behaviorist Theory Aggression is a problem that affects all members of society. There is no doubt that aggression pays off for some. Parents who yell and threaten punishment get results. The child who hits the hardest gets the toy. The brother who is willing to be the most vicious in a fight wins. The teacher who gives the hardest test and threatens to flunk the most students usually gets the most study time from students. The spouse who threatens to get the maddest gets their way. The male who acts the most macho and aggressive gets the praise of certain groups of males. For decades psychologists have attempted to find the causes of aggression. The focus of ...

    ... AP) to a cellular receptor. Receptor molecules can be proteins (glycoproteins), or the sugar residues present on glycoproteins or glycolipids. Some complex viruses, for example, Poxviruses and Herpesviruses may have more than one receptor-binding protein, therefore, there may be alternative routes of uptake into cells. The expression or absence of receptors on the surface of cells largely determines the tropism of most viruses, that is, the type of cell in which they are able to replicate.  Penetration Unlike attachment, viral penetration is an energy-dependent process; that is, the cell must be metabolically active for this to occur. Three mechanisms may be involved:  Tr ...

  • 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 ...

  • Alcoholismnature Or Nuture - 1,645 words
    Alcoholism-Nature Or Nuture? INTRODUCTION: Alcoholism can affect anyone. It has enormous costs as it pertains to societies, families, and individuals. It is not prejudicial towards any race, color, sex, religion, or economic level. Although we do have ideas as to what alcoholism is, what we do not know is the exact cause(s) of this problem. Researchers are continually seeking answers to the long-standing nature versus nurture debate. Different views are split between a biological paradigm and a physchological paradigm. No one explanation seems to be better than another is. I will present views of the effects alcoholism has on society and an insight to the factors that serve to fuel the natur ...

  • Alternative Cinema - 1,558 words
    Alternative Cinema The term alternative cinema has certain connotations. To many, it is not alternative, instead it is the way cinema was meant to be viewed, in that the viewer should be able to define the film in their own personal terms. In the following essay, I will firstly examine what the term alternative cinema means, and secondly how Brechts theories are evident in many elements of the films that have been pigeon-holed as alternative cinema. The word alternative is described in Collins English Dictionary as: "Denoting a lifestyle, culture, art form, etc., regarded by its adherents as preferable to that of contemporary society because it is less conventional, materialistic, or institu ...
