Capital Asset Pricing Model - Essay Example The underlying theme associated with CAPM is investor’s relationship and the advantages which an investor can attain by the application of this model. The investors are linked in two ways with this technique; one is the time value of money and the other is the risk factor involved in a project. The time value of money can be depicted using the risk-free (Rf) rate in the formula which can then be compensated with the investors for placing money in any investment after a certain period of time. The risk part of CAPM formula is used for representation of risk and calculates only the amount of compensation which any investor can undertake for facing any additional risk. These financials can be calculated using the risk measurement tool i.e. beta, which has the ability to compare the returns of the asset towards the market after a certain period of time having definite market premium. According to the CAPM tool, the expected return of a security calculated on a portfolio is equal t o the rate of a risk-free security, which is further raised by including a risk premium. If this is expected return is not able to be ascertained or is not able to even beat the expected return then the required return and the investment will not be undertaken. Practical Implementation of CAPM This pricing model which is regarded as CAPM was put forwarded in the year 1960 and since then it is under deep influence of criticisms. The argument of such critics involves hypothesis that CAPM does not put forward realistic market conditions.

An Evaluation of Case Studies and Their Contribution to Cognitive Neuro

Cognitive psychology is the study of the brains internal processes that guide behaviour; to study cognition, psychologists examine case studies of patients with damaged brains that can infer areas, and functions involved in particular processes. Patient studies have provided insights into the processes that take place within our minds, and have enabled psychologists to create models, which can be tested and fractionated. Cognitive neuropsychology has developed from cognitive psychology to become a discipline in its own right; it investigates the function and structures of the brain involved in cognitive processes and should not be confused with cognitive neuroscience, which is primarily concerned with neural structures and their functions. Cognitive psychologists investigate processes using case studies of brain-damaged patients, these are then analysed to build models that represent normal cognitive processes. This essay will examine the contribution case studies have made to the development of cognitive neuropsychology as a discipline in its own right and draw attention to issues surrounding the use of brain damaged patients to infer cognitive functions and processes. At the same time, it will evaluate the contribution that case studies have made to our understanding of cognitive processes. Cognitive processes are the unseen systems used by our minds to complete tasks such as solving problems, recognising an object, or learning a language. These unseen mental processes take place in the brain, which is a complex piece of equipment often compared to a computer. When the internal workings of a computer are exposed, all that we see are microchips, circuit boards, hard drives and other assorted pieces, which, all work and ... ...gy; therefore, case studies have contributed to the development of this branch of psychology as a discipline in its own right.

Jonathan Edwards

In Jonathan Edwards’ personal narrative, he uses language to convey a remorseful attitude towards his own spiritual condition. The imagery of hell as seen by Edwards creates a punishment in â€Å"the lowest place in hell. † He feels like he is the â€Å"very worst of all mankind. † In the simile, â€Å"as bad as the devil himself,† his followers make him feel as though his â€Å"wickedness† and â€Å"vileness† are greater. This portrays his remorseful attitude.By utilizing the simile, â€Å"like an infinite deluge or mountains over my head,† Edwards depicts the severity of his wrongdoing as being of such magnitude that it is â€Å"swallowing up all thought and imagination. † The use of repetition in â€Å"Infinite upon infinite— Infinite upon infinite! † supports Edwards’ view of his wickedness as â€Å"an abyss infinitely deeper than hell. † This expresses his internal pain and anguish. Edwards proce eds to use the phrase, â€Å"nauseous and detestable to me,† to describe his sense of self-loathing.He feels as if he does not morally deserve to be â€Å"exalted and raised up to the infinite height of all the fullness and glory of the great Jehovah. † Throughout the narrative, Edwards is vividly describing his belief that if it were not for the â€Å"sovereign grace† of his Lord, that the earth would simply not bear him or all humanity for a single moment because as far as he is concerned, we are all corrupt individuals- creatures even, that spend our lives in the service of God’s enemies. It is through all the aforementioned that he illustrates his remorseful sentiment in his personal narrative.

The Accuracy Of An Individual s Memory - 1506 Words

Eyewitness report or testimony refers to an account by people of an event they have witnessed. These are commonly used for criminal conviction by judges and jurors. It is a product of reconstructive memory where we piece together bits of stored information that seems real and accurate. The accuracy of an individual’s memory comes into question as it could lead to wrongful conviction. Some factors affecting accuracy of eyewitness reports include confirmation bias, misinformation effect and influence of violence and anxiety. The first part of the essay will explain these factors; the second part will discuss the ability to retrieve information from our long-term memory. Eyewitness testimony can be affected by confirmation bias. It is defined as â€Å"a tendency for eyewitness memory to be distorted by the eyewitness’s prior expectations†, (Eysenck and Keane, 2015, p.321). Barlett (1932) argues that schema causes the distortion. Schemas are generalized ideas or pack ets of knowledge stored in long-term memory. It is a cognitive framework to help us organize and construct memories based on expectations and our existing assumptions about the world. In the event of new situations like witnessing a crime, the information encoded into memory will not correspond exactly to what was encountered. An example would be study conducted by Bartlett (1932), where British participants were asked to memorize a Native American storybook. The story became significantly shorter, details were lost, andShow MoreRelatedAccuracy Of The And How Fast A Person Can Complete A Certain Amount Of Math Problems1567 Words   |  7 Pages Speed-Accuracy Tradeoff in Mathematics Unjanee’ Wright Wright State University Psychology 3020L-05 TA: Joseph Glavan â€Æ' The purpose of this study is to determine how accurate, and how fast a person can complete a certain amount of math problems within only a few mins; then, determine how this relates to stress.
