Outline and evaluate two social psychological explanations for aggression
Outline and evaluate two social psychological explanations for aggression While there are many different approaches in psychology, perhaps the most believable, and ultimately provable approaches to aggression come from the social psychological approach: social learning theory and deindividuation. While the two theories differ in their context, they both assert that the explanations of behaviour, in this case aggression, originate from the situational context emphasising little importance on other factors such as biology, evolution or cognitive processes. The social learning theory (SLT) approach to aggression largely originates from the somewhat infamous work of Bandura. While SLT comes under the large umbrella term of behaviourism, it goes far beyond the simple stimulus response model, explaining in depth more complex and perhaps realistic explanations for behaviour. Aggression is learned either indirectly: through observational learning and only replicated if vicarious reinforcement occurs, or directly. This is where aggressive behaviour is directly reinforced. While both are a form of operant conditioning, the direct approach parallels the ideas much closer. Bandura outlined the following four steps in the modelling process of SLT: Attention, retention, reproduction and motivation. Attention is increased if the model is more prestigious, attractive or similar. This causes
Assess the significance of the role of individuals in reducing racial discrimination in the USA throughout the period 1877-1981.
History Coursework: Part B Assess the significance of the role of individuals in reducing racial discrimination in the USA throughout the period 1877-1981 Between the periods of 1877-1981 there were many significant figures who contributed towards reducing racial discrimination in the USA. Although without events such as the Montgomery Bus Boycott, WWII or the actions of the NACCP to change attitudes towards African Americans, these individuals would have had little effect. The likes of Booker T Washington and Du Bois set the foundation for civil rights along with the Second World War; however other individuals such as Martin Luther King help to actively progress the movement. Along with this the government and various presidents more so in the latter of the period of 1877-1981 helped to change attitudes and enforce legislation which was vital in reducing racial discrimination in the USA. Booker T Washington began to provide the foundations to the civil rights movement in his actions. Although I believe that during this early period of the movement little was achieved, Washington was still able to provide education, and show African Americans that they had a future and it was at their own mercy. This helped to relieve some who were less fortunate. On the other hand Du Bois took a route which directly campaigned for civil rights for African Americans; alike to Washington he
Outline how and why federalism has changed since the 1960s.
Page 1 of 2 Outline how and why federalism has changed since the 1960s. In the 1960s, the government had a creative federalist approach. The aim of Lynden Johnson's Great society programmes was to try to eliminate poverty within the US. This in turn meant large government grants were given to states, which was seen to increase the level of interference from the federal government. Johnson also provided categorical grants instead of block grants, which meant the states had much less control over their spending. He also supplied a lot of federal aid, increasing the dependence of states on the federal government. It wasn't just the executive increasing the role; the judiciary were also pushing the government this way, with cases such as Gideon vs. Wainwright and Miranda vs. Arizona. Since the 1960's the some have stated that New Federalism has been the main objective of the executive and judiciary due to the previous creative federalism. From the 1970s there was an ideological shift, with the rejection of liberal values from the 1960s. President Nixon started the development of the idea that the federal government was too powerful, and that the states needed to have more power of their local rights. He felt that the federal government should be small to promote self reliance and the American idea of 'rugged individualism'. As a reaction to creative federalism and the great
Compilers and Interpreters
Compilers and Interpreters There are two types of translator for converting a high-level language such as Pascal into machine code; compilers and interpreters. These relieve programmers of the tedium and complexity of low-level programming and hence make programming considerably easier and less error prone. Compiler This type of translator takes the whole source code and compiles it into object code. The object code (sometimes called machine code) can then be run. Pascal is an example of a programming language that uses compilation. Interpreter This type of translator takes the source code and translates the first line of the program, and then executes it. It then does the second line, and the third line, until it gets to the end of the code. BASIC, LISP, Prolog and APL are examples of programming languages that uses interpretation. Compilers plus Interpreters. Some programs written in languages such as JAVA are both compiled and interpreted! A program is firstly compiled into an 'intermediate code'. It is then distributed to users who use a wide range of computers such as Mac or PCs. These computers then run their own 'interpreter' to convert the compiled code into a code they can use. Languages such as JAVA are said to be platform-independent, because any program written in that language can run on any machine. These types of languages are ideal for use on the

Marketing Management - Swisher Mower and Machine Company.
MBA5009 Marketing Management Group Report Of Case 5 Swisher Mower and Machine Company Submitted by Zeng Min, Bernice Ellen Novidia Adisoebrata Tan Xiao Ling, Linda Liu Bei, Pat Paul Lim Suparto Quach Thi Thu Hien Huang Yue Hong, Sarah NUS Business School National University of Singapore Wayne Swisher, President and Chief Executive Office of Swisher Mower and Machine Company (SMC), was weighing the proposal of a private branding arrangement for SMC's line of riding mowers. He thought the inquiry presented an opportunity but details should be studied more closely. Situation Analysis: Company Background: Established in 1945 by Max Swisher, SMC grew steadily with unit volume for SMC riding mowers peaking at 10,000 units with sales of $2 million in 1966. In the 1990s, the unit volume remained constant with around 4,250 riding mowers per year. Compared with 1,263,000 unit sales in riding mowers and tractors industry, SMC only occupied around 0.3% market share. Max Swisher, the current CEO, thought maintaining a small company image had also been an important aspect of his business philosophy, which led to the good personal relationships with dealers and customers alike. SMC produced limited but differentiated products. SMC's flagship product, the Ride King, was credited with the first zero-turning-radius riding mower. SMC also produced a trail-mower called T-44

Cellular Structure and Function
Cellular Structure and Function Introduction Cells are organised together into functioning groups called tissues. These groups of cells organise together to perform a specialised task. There are four basic types of tissues found in the human body; these are epithelial, connective, muscular, and nervous. The following text aims to explain the structure and function of these tissues as well as ovum and sperm cells. Epithelial Tissue Epithelial tissues, as with all different types of tissue, can be found all over the body, they generally line the inside or outside of a body cavity. The cells are anchored down by basement membranes and form in different shapes such a flat, cuboidal, and columnar. The below text details several different types of epithelium cells that can be located around the body. . Stratified Squamous Epithelium Stratified squamous epithelium cells are present in areas of the body that are very moist and subject to abrasion, such as the mouth, esophagus and vagina. The cells are packed densely together and are very flat and irregular in shape. The tissue functions to provide a barrier to entry to inside the body and protects underlying tissues from friction and drying. Figure A. above shows a drawing of the epithelia from an overhead point of view, in shape they are very similar to that of a fried egg. Figure B. shows the cells from a side-on point of

Outline and Evaluate research (theories/ and studies) into the relationship between stress and physical illness. 18 marks Stress is an example of a behavior and experience explained in physiological and psychological terms. Recently awareness has been highlighted concerning harmful effects of stress on our lives and how it can be managed and prevented. Stress is often associated with anxiety, strain, tension, distress and fatigue. The effects of stress include biochemical physiological and psychological changes, most show with ill health or unusual behavior. Therefore medical and psychological research findings in this area are crucial in aiding our understanding of the issue. Stress is usually the way we perceive stressors e.g. divorce, and the way we feel we are able to cope with things. If we cannot cope with the situation we are faced with, then we experience psychological and physiological responses to the stressor. In the short term, stress can be quite stimulating and motivating. In the long term stress can result in illness and even death. During a state of stress, the sympathetic area of the nervous system stimulates the adrenal medulla to release the hormones adrenaline and non-adrenaline into the bloodstream. These hormones stimulate heart rate and cause the body to use extra energy resources in the body. This enables the body to deal with the stressor by
