Thomas Alva Edison Is Considered One Of The Greatest Inventors In Hist

Thomas Alva Edison is considered one of the greatest inventors in history. He was born in Milan, Ohio on February 11, 1847 and died in 1931. During his life he patented 1,093 inventions. Many of these inventions are in use today and changed the world forever. Some of his inventions include telegraphy, phonography, electric lighting and photography. His most famous inventions were the phonograph and the incandescent light bulb. Edison did some of his greatest work at Menlo Park. While experimenting on an underwater cable for the automatic telegraph, he found that the electrical resistance and conductivity of carbon varied accordingly to the pressure it was under. This was a major theoretical discovery, which enabled Edison to invent a pressure relay using carbon rather than magnets, which was the usual way to vary and balance electrical currents. In February of 1877 Edison began experiments designed to produce a pressure relay that would amplify and improve the audibility of the telephone, a device that Edison and others had studied but which Alexander Graham Bell was the first to patent, in 1876. By the end of 1877 Edison had developed the carbon-button transmitter that is still used today in telephone speakers and microphones. Many of Thomas Edisons inventions including the carbon transmitter were in response to demands for new products and improvements. In 1877, he achieved his most unique discovery, the phonograph. During the summer of 1877 Edison was attempting to devise for the automatic telegraph a machine that would transcribe a signals as they were received into a form of the human voice so that they could then be delivered as telegraph messages. Some researchers had theorized that each sound, if it could be graphically recorded, would produce a distinct shape resembling short hand, or phonography, as it was known then. Edison hoped to make this concept real by employing a stylus-tipped carbon transmitter to make impressions on a strip of paraffined paper. To his amazement, the barley visible indentations generated a vague sound when the paper was pulled back beneath the stylus. In December 1877 Edison unveiled the tinfoil phonograph, which replaced the strip of paper wrapped in tinfoil. Many people would not believe what they were hearing including a leading French scientist who declared it to be a trick device of a ventriloquist. The publics amazement was quickly followed by universal approval. Edison became famous all around the world and was dubbed the Wizard of Menlo Park, although ten years passed before the phonograph was transformed form a laboratory curiosity into a commercial product. His most famous and most commonly used invention is the incandescent light bulb. American scientists including Samuel Langley needed a highly sensitive instrument that could be used to measure minute temperature changes in heat emitted from the Suns corona during a solar eclipse along the rocky mountains on July 29,1878. To please those needs Edison invented a microtasimeter employing a carbon button. This was a time when great advances were being made in arc lights so that electricity could be used for lighting in the same fashion as with small, individual gas burners. The basic problem seemed to be to keep the burner, or the bulb, from being consumed by preventing it from overheating. Edison thought he would be able to solve this by coming up with a microtasimeter-like device to control the current. He proclaimed that he would invent a safe, mild, and inexpensive electric light that would replace the gaslight. Inventors had been attempting to devise the incandescent light bulb for fifty years, but Edisons reputation and past achievements commanded respect for his bold prediction. As a result, a group of leading financiers, including J.P. Morgan and the Vanderbilts, established the Edison Electric Light Company, and advanced him $30,000 for his research and development. Edisons idea was to connect his lights in a parallel circuit by subdividing the current so that the failure of one light bulb would not cause the whole circuit to fail. Some well-known scientists predicted that such a circuit could never be possible, but their findings were based on systems of lamps with low resistance (the only successful type of electrical light at the time). Edison, however, determined that a bulb with high resistance would

ACC403 (MoD 2 SLP) Present Value and Capital Budgeting Essay

ACC403 (MoD 2 SLP) Present Value and Capital Budgeting - Essay Example It has been seen from the historical price chart that the price of the stock has been increased gradually in the last two years. From the historical prices it can be assumed that the price of the stock will increase but there are many other factors associated with the assumption. The death of Mr. Steve Jobs, the founder and C.E.O. may create negative impact among the investors. Despite of this negative factor the researcher is expecting that the price of the stocks of Apple will increase based on the historical price and the fact that even after the death of Mr. Jobs the stock price of the company has increased gradually. The stock price of Apple was 339.32 on January 3, 2012 and it was 447.28 on January 3, 2012 (Yahoo Finance, 2012). So the rate of return is 31% where the savings account interest rate of America is less than 1% (Bank of America, 2012). So it would be the right decision to buy the futures of Apple stock instead of investing in the savings account. Every company needs to acquire some new asset or implement some new product for expanding their business. Different types of risks are associated with the company. In this paper the researcher has described the factors associated with a hospital when they are going to acquire new machinery. The hospital is going to buy a GE LogiqBook XP Portable Ultrasound Machine. The cost of the machine is $15,999 (Absolute Medical Equipment, 2011). Purchasing of the machine can be funded from the retained earnings of the hospital. The portable ultrasound machine certainly enhance the portfolio of the hospital as it would help the hospital to acquire more customer, as it is more patient friendly. The cash flow from the investment can be assumed from the past data of the hospital. The researcher has to find out the number of patients in the last month and the last financial year. Based on the data the researcher can assume what would be the number of patient when

Local Business Lawsuit Essay Example | Topics and Well Written Essays - 1000 words

Local Business Lawsuit - Essay Example Summary of Lawsuit Goodyear Time & Rubber Company, operating a plant in Danville, Virginia was sued by the US Department of Labor for alleged discrimination in hiring personnel during the latter part of the 1990s (Lindsey, 2006). The alleged discrimination was directed against hundreds of female applicants. As a result of such denial, the lawsuit was filed against the company (with headquarters in Akron, Ohio). The lawsuit asked the court to hire the discriminated women, pay for back wages, and provide other benefits due to workers (Lindsey, 2006). According to the Labor Department, the company implemented a procedure in the hiring and selection of employees from January 1998 to June 1999 that is gender-discriminatory against female applicants at the entry level (Lindsey, 2006). The case stemmed from the routine procedural review conducted by the department’s Federal Contract Compliance Programs in Richmond that showed such discriminatory hiring. The company, on the other hand , strongly denied such allegation. Goodyear, as a federal contractor, is not allowed to discriminate in hiring based on race, religion, color, sex and ethnicity (Lindsey, 2006). The Philadelphia labor office acting Regional Director Patsy Blackshear said that companies contracting with the federal government must ensure that equal opportunity program is being implemented at the highest level, and that includes discrimination in the hiring process. The complaint was lodged at the Office of Administrative Law Judges in Washington, D.C., the trial court of the Labor Department. Risk Management Risk management refers to the identification of the different kinds of risks that affect an organization that could have an impact upon the business (What is Business Risk, n.d.). After identifying the risks, probability of its occurrence must be determined. Then, a plan should be devised, and lastly, to monitor the effectiveness of the plan (What is Business Risk, n.d.). The risks that a busines s may have include physical and environmental risks, financial risks, employee risks (What is Business Risk, n.d.), and several others depending on the nature of the business. In the present case, the risk present involves the internal policy of the organization. By ignoring the equality laws mandated by the government, Goodyear presents itself as vulnerable to litigation risks that may come from the Labor Department or the persons discriminated upon. As a mitigation action that Goodyear could do, it should ensure that men and women are equally represented in its workforce, no matter where they are located in the US. During the period reviewed by the department, discrimination against women was seen since hundreds of them were not hired in one year while men were continuously absorbed into the labor force. Thus, the Human Resources Department of Goodyear should implement a hiring policy that would make sure that men and women are more or less equally hired within a specific period. Ethical Considerations The hiring process may be influenced by discrimination on the part of management if not guarded against. Thus, the management must establish a detailed hiring policy that takes into account the civil rights protected by the laws. Ethical considerations refer to doing what is deemed to be right and proper as dictated by society, the code of ethics of organizations, or the best practices. Therefore, doing something against the identified good practices would be unethical for the organization. The laws applicable in

Mental Health And Community Care Report

Mental Health And Community Care Report 1.0 Introduction This report will explore on mental health and community care within the historical view of community care and the impact of ideological perspectives that have influenced it. It will further analyse the benefits and shortfalls since its implementation, taking into account the impact of the 1990 NHS Community Care Act and current reforms will be considered. Again, the effects of poverty and social exclusion for those accessing community Care will be discussed. The author will further consider key aspects of mental health and the gradual transition from insitutionalisation to deinstitutionalisation (community care) since the early 1950s will be discussed. Recommendations shall be made regarding, especially, how the mental health system (including community care) could be improved. HISTORY In the pre-medieval period people believed that mental illness was a result of the possession of the human body (patient) by evil spirits. In order to get these perceived evil spirits out they drilled holes in the skull of such people. Andreasen (2001) tries to give credence to this by mentioning that scientists have found fossils of drilled skulls that are about 10,000 years old. During the middle ages a belief in Europe was that witchcraft was the reason for mental illness. As a punishment such people with mental illness were killed by burning, hanging or drowning. Some were put in government institutions called poorhouses. By the 1500s many European nations had built special institutions to separate the mentally ill from the rest of society. One of the most famous of such institutions was the St. Mary of Bethlehem in London which was built in 1247 and declared a hospital exclusively for the insane by 1547 It is widely known widely known as Bedlam. According to Butcher et al (2009) , inmates suffered from unsanitary conditions, beatings and other harsh treatment. This included violent patients being used for shows display shows for the public to pay and watch, while gentler patients were sent to beg for charity on the streets. A lot has changed in the United Kingdom especially with the relative improvement in the mental health institutions or hospitals and also with the emphasis on community care since the 1950s. In fact some see care in community, usually referred to as community care in as a replacement for hospitalization and any other form of institutionalization of people with mental ill health. However, these historical perspectives of mental illness can stick in peoples minds, and can still cause stigma today. Goffman(1961) Community Care Skidmore (1997) describes community care to be the various services available to help individuals manage their physical and mental health problems in the community with dignity and independence in order to avoid social isolation. Similarly, Clough and Hadley (1996) explained that community care can be means of providing the right level of intervention and support to enable people to attain utmost autonomy and control over their own lives. The author notes that in order for these to be achieved, it will require support by formal and informal carers input The development of community mental health care has evolved over a period of years as opposed to institutional care. Goffman (1961) stated that social and political changes influenced the movement away from isolation of mentally ill in old Victorian asylums towards their integration into the community. Currently, there are various services that have been put in place to support people who have mental health problems and are leaving in the community. These services includes (Sainsbury centre of mental health 2003) HISTORY Community care has historically always been financed through a mixed economy financed by both the state and by users charges, and provided by voluntary sector organisations, commercial profit organisations, the state and the family (Lewis. J). Social scientist have made an association with informal care to family member participation. Informal care has historically been the origins of the present day community care. The origins of the term community care appear too traced back to the Royal Commission on Mental Health and Mental deficiency (1957) which notes The Development of Community Care (Bulmar 1987). However community care has a multiple meaning (Bulmar 1987) and historical official use failed to distinguish these differences. problem as it is a product in part of at least, the impact of political process and policy development. According to Levites et al (2007), Social exclusion is a difficult and multi-dimensional process which involves the lack or denial of resources, rights, goods and services, and the inability to participate in the normal relationships and activities, available to the majority of people in a society, whether in economic, social, cultural or political arenas. Similarly, Townsend (1979) defines poverty as the absence or inadequacy of those diets, amenities, standards, services and activities which are common or customary in society. I will argue from the above definition that, social exclusion and poverty are linked. Pierson (2009) argues that government likes to use the term to hide poverty. Barker (2003) stated that in recent years the government has launched a range of initiatives to help tackle social exclusion and reduce inequalities which has specific objectives relating to education health, employment, crime prevention and wider social well being. These initiatives include the nee d for communities to put into action; supportive and innovative approaches in order to promote local involvement to support people with mental health problems, as this will minimize exclusion. The structure of care in the community (in relation with mental health) can lead to poverty because many people who experience mental distress, experience stigma and discrimination as well. These issues may make it hard for them to find adequate housing or access employment. As a result, people can become seriously isolated and excluded from society. If this also includes being excluded from working life, then this may lead to poverty. Social Exclusion Unit (2004). Usual Mental Health Professional Team There is now a range of more specialist community mental health teams (CMHTs) in the United Kingdom (UK) these includes: Home treatment, Crisis intervention, Early Intervention, First episode psychosis, ABT (assessment and brief treatment), Continuing care, Rehabilitation, Assertive Outreach and Forensic services. These teams are as a reform to government policy to promote community care. They work with people with mental health problems by helping them to become independent, working with them to develop their strengths, working together to resolve problems and many other supports that enables the promotion of wellbeing. A typical mental health professional team include the psychiatrists who prescribe medication, the psychologists who administer and interpret psychological tests, the psychiatric nurses who administer prescription medication and give injections, and the social workers who have specialized knowledge in assessing and planning treatment (Suppes and Wells, 2000). Conclusion/Recommendations The gradual transition from institutionalisation to community care since the 1950s is certainly not unhealthy. It only would yield no positive results if, borrowing the words of Skidmore (1994), people with mental health problem are not just decanted into the community without an identification of the informal carers. Social exclusion is a major concern in promoting recovery for those experiencing mental health problems and if not tackled on time will discourage and lead to relapse for those who have experienced or facing these difficulties. Promoting social inclusion will usually includes promoting equal opportunities for those who are excluded and experiencing discrimination so I can therefore say there is a clear link between promoting social inclusion and promoting equality and diversity to alleviate poverty. I also believe that the Mental health practice which is currently driven by the National Service Framework which aims at reducing discrimination and social exclusion to improve mental health of the population should be supported by mental health professionals to build social inclusion into clinical practice by including in the care plans of users their aspirations for work, education, relationship and other chosen journeys of recovery. The following recommendations are worthy of consideration in the bid to improve the current mental health system in the United Kingdom. Research concerning how institutional and community care can be improved Reduction of stigma against people with mental illness since that can jeopardize their speedy recovery whilst in the community. Involvement of informal carers in decision-making regarding treatment of patients Attend to the health needs of informal carers Informal carers should be trained on how best they can take care of patients. The British government should invest more in community care especially with the needs of patients in communities. Deinstitutionalization should be done more gradually and carefully especially in the case of people with chronic mental illness.

Heart of Darkness and Lord of the Flies :: comparison compare contrast essays

Heart of Darkness and Lord of the Flies    Seldom are works as brilliantly written as Conrad's Heart of Darkness or Golding's Lord of the Flies.   There are effective comparisons and contrasts between the two novels. The novels deal with many similar issues and contain many of the same themes.      Many of the themes present in Heart of Darkness and also present in Lord of the Flies.   Both novels deal with the theme of civilization versus savagery.   Also, both novels imply that every man has a heart of darkness or an evil that is usually drowned out by the light of civilization. However, when removed from civilized society, the raw evil of untamed lifestyles within his soul will be unleashed. For example,   in the Heart of Darkness the main character Marlow journeys up the Thames river and as he gets further away from civilization, the more he journey's into a heart of darkness.   A darkness where societal morals no longer exist and savagery has taken over.   In the Lord of the Flies the boys in the novel are stranded on an island and the longer they stay on the island and are absent from civilization the more savage like they become.         Another similarity between the two novels is that the parallels between the protagonists and the antagonists are quite similar.   Both the novels have a character who willingly gives into his heart of darkness, and a character who sees the savagery of those who are consumed and fights to return to civilization.   For example, in the Heart of Darkness Kurtz gave into his heart of darkness and let his evil tendencies take over.   He was a one point a man who values morals but gave into his evil side when removed from civilization.   Marlow on the other hand also journeys away from civilization but he does not let his values deteriorate such as Kurtz.   In Lord of the Flies Jack gave into his evil side and becomes savage like, and begins turning against the ones who were his friends.   Ralph on the other hand was not as easily consumed by his evil side.   Until his death, Ralph   realized the savagery of the others especially Jack.

Literature Review Train Travel Essay

In order to conduct a thorough review of train travel it is important to first place my own work within the wider context of the existing knowledge in relation to this topic. By looking at studies which have already been conducted it is possible to observe questions which remain unanswered in this field and to look critically at existing literature in order to give my personal study a greater sense of purpose and to ensure that it makes significant contribution to the field. Social Construct of Train Travel A particular area of study relating to train travel which seems interesting to me is that which is pointed out by Watts (2008). In her paper she examines the social, imaginary and material work involved in making a journey by rail. Following ethnographic research consisting of quotations and photographs the author argues that rail passengers are spatially distributed when they make a journey by train. In her analysis she points out that a great deal of research has been conducted into the way in which time and space are constructed in society, however few researchers have conducted a specific analysis of the items and people involved in this creation. As a result this is an area I am keen to investigate as the way in which time and space is created is an area which invites more specific investigation and simultaneously this topic in relation to train travel has had little academic attention. Therefore by investigating this topic I feel I would be able to fill a gap in existing research. A further article which builds on this notion of the social construct of travelling by rail is that of Bissell (2008). In his study he looks at â€Å"some of the fluid relationships between everyday visuality, materiality and mobility through practices of contemporary railway travel in Britain† (1) The article looks primarily at the visual issues in train travel including the interior of the carriage and the landscape viewed through the window in relation to how these affect the perceptions of time, space and location throughout the journey. Such a take on train travel is something which I am very interested in and by using the conclusions made in this paper I would be able to add to the cannon of debate on this topic to contrast the findings of this study with those from an American perspective, to broaden this debate into a multi cultural arena where it may be the case that a vastly different social construct is created through train travel. This notion is extremely interesting to me and is one which, as it is yet to be developed from a transnational context, would therefore allow me to add to the academic body of knowledge on this topic. Train Travel for Business Along with the social construct of train travel another area which much literature has been conducted into is train travel in relation to alleviating problems for businesses. As train travel is often undertaken by business professionals who may need to get from two areas which are relatively far apart and are both subject to high levels of street congestion the degree to which train travel is an effective way for businesses to get to different locations for meetings or negotiations I feel therefore is an important one. One paper which has done this in relation to the relative effectiveness of train travel versus air or road travel for businesses is that of Bhat (1995). In his paper Bhat deploys an extremely qualitative and thorough evaluation of what he terms the ‘independence of irrelevant alternatives’ (IIA) in order for him to be able to come to the conclusion that different approaches to this topic elicited a different set of results. As this paper had a heavy weighting on the effectiveness of specific models in investigating this topic I feel that one way in which it can be improved is to select an approach or a model from the outset, and then stick with this throughout in order for the conclusion to be more orientated around the travel mode as opposed to the model itself. Nonetheless this paper does point out to me that the heteroscedastic model is superior to both the multinomial logit and nested logic models in the quality of results it is able to generate and therefore it will be worth me bearing this in mind when I come to conduct my own research. Another paper on a similar topic to this explores the relationship between the timing of your journey and the choice of which transportation mode you take. Conducted by Nurul Habib et al. (2009) this paper conducts a correlational analysis of these two decisions and comes to the conclusion that unobserved factors contributed to both the decision of which time to undertake your journey and which transport mode to take. Something I found particularly helpful about this paper was that it pointed out the tendency for congested peak travel periods to expand which is a phenomenon known as ‘peak spreading’. As this paper provides empirical evidence for this notion is therefore justifies further investigation owing to the importance of travel between cities in today’s society. Similarly, as this paper utilises a multinomial logit model, a discrete-continuous econometric model and a continuous time hazard model the issues relating to the effectiveness of these models has been highlighted to me as an area I will need to conduct a further amount of research in to in order to ensure that the method I ultimately select is effective in generating reliable results. Along with this issue of which model to apply to my research a study by Kroes and Sheldon (1988) point out another issue I should be aware of when conducting research into train travel. In their article they conduct a review of the stated preference method in the transport sector by another of other academics and assess the value of using this method in comparison to other similar methods to assessing why people have selected the particular mode of transport. As this article covers a range of other train transport related studies it therefore is useful in assessing the literature in this field as a whole as it has a rather broad scope. By looking at the individual studies and the successful and unsuccessful elements of them I am therefore able to select a method which suits my particular study most aptly and as a result conduct a thorough and exhaustive investigation into my chosen area of train travel. Travel Time Key names in the field of rail travel include Laura Watts and David Bissell. Something which they have both written about is the notion of travel time in relation to passenger experience. In a study by Watts and Urry (2008) the authors attempt to provide evidence to dispel the myth that time spent travelling is wasted and dead. In order to encourage funding into travel projects the authors propose that rather that attempting to minimise travel time, by linking the notion of travelling with activities and fantasies they therefore suggest that the perception that travel time is wasted is therefore incorrect. Through looking at activities such as engaging with other passengers, accessing wireless networks, views out the window and using items you have packed in your bag they therefore provide evidence which ultimately represent travel time as a useful being of time where practical and fantasy activities can be indulged, thus encouraging investment into travel projects and infrastructures. I find this research particularly useful as it has called for a revaluation of previously taken for granted attitudes towards travelling by train. By looking at the topic more broadly and dispelling common misconceptions the authors are able to create an article which both covers brand new ground and gives attention to an under investigated issue. The theoretical approach they establish therefore is something I wish to build upon in my own study as the issue is so recent it therefore is yet to have any support or criticism surrounding it. A further study by Bissell also investigates this topic however from a different perspective. Bissell (2010) looks at the notion of community and atmosphere within a train carriage. He notes something which I find interesting, that there is a certain atmosphere within a train carriage which has a powerful effect on the traveller in terms of a reticent passivity which contradicts a set of forces which work when travelling by train which prime an individual to act. As far as I am aware this societal approach to the atmosphere on a train carriage has only been conducted in relation to psychology and obedience before and therefore it is very interesting that Bissell has looked at it within the field of transport. Whilst I feel that this study is extremely relevant and is something a great number of people may be able to relate to some criticism I have is that the notion he is describing is extremely intangible and whilst he does provide extensive primary research as evidence the atmosphere is difficult to pin and down and evaluate scientifically. Another study on this topic is that of Ole (2009). This study looks at the idea of mobility in urban areas. The author describes the tendency for modern cities to be represented not just by their static venues but also by their transit spaces and argues that there should be a re configuration of the way in which identities of place are conceptualised and that transit spaces ought to become a location for meaningful interaction and pleasure. As with the Watt and Urry article this paper calls for a revaluation of the attitudes towards train travel and therefore provides a useful framework which forms a base upon which it would be possible to build upon and expand in my own study. Conclusion Throughout my literature study I have been able to identify the key theorists in the field of train travel and highlight some potent and relevant issues in this area of study. By looking critically at research which has already been conducted I am now able to ensure that my own study brings new ideas into academic discourse and that my investigation does not cover ground already subject to analysis. The gaps I have noted and other observations made throughout the body of my text therefore now place me in an ideal position to be able to come to a conclusion based on relevant research which will be will informed and critical in its scope.

Angelou essays

Angelou essays When Angelou was three and her brother Bailey was four, their parents divorced. They sent the children to live with their paternal grandmother, Annie Henderson, and her son Willie in Stamps, Arkansas. Annie, whom the children soon began to call "Momma," was the proprietor of the only store in the black section of Stamps. During the cotton harvest season, Momma awoke at four in the morning to sell lunches to the crowd of cotton laborers before they began the day's grueling work. In the morning, the laborers were full of hope and energy, but, by the end of the day, they barely had energy to drag themselves home. They always earned less than they hoped, and they often voiced suspicions about weighted scales. For her whole life, the stereotype of happy, singing cotton pickers enraged Angelou. The laborers never earned enough to pay their debts, much less enough to save anything. . What is the significance of the sermon delivered at the annual revival? The black Southern church constituted an avenue for subversive resistance. At the revival, the preacher gave a sermon that criticized white power without directly naming it. He never mentions white people, but his diatribe against greedy, self-righteous employers was clearly an attack on the miserable wages white farmers paid to black field labor. He criticized people who give charity with the expectation that the recipient would be humble and self-belittling. The implicit meaning of his statement was a diatribe on so-called white charity. Often, white people would expect the black recipients of their "charity" to avoid all signs of having pride in themselves or their identity. The people at the revival could entertain fantasies of their oppressors burning in hell with the support of divine will. For the most part, they shouldered the burden of their disadvantages of poverty and discrimination with resignation, attributing their suffering to God's will. However, the black church pro vi...

Free Essays on The Dark Side Of A Streetcar Named Desire

The Dark Side of A Streetcar Named Desire In A Streetcar Named Desire, written by Tennessee Williams, the characters presented represent Williams' own view of society. In Streetcar, Williams has created a medium to observe and reflect upon the darkest aspects of society and the result of these societal downfalls. Williams has portrayed numerous societal downfalls, such as the idea that he (or she) who tries to hide his true self and lie to the world ends up, above all, hurting himself. This statement, which lies just below the surface in Streetcar, reflects the difficulties Williams had in finding his own place in life. Williams created that this play as a sort of "slap" toward a society which rejected Williams and his way of telling the world, "If you keep behaving like this, the whole place will go stark-raving mad!" This is distinctly seen in both the suicide of Blanche's young husband and her own decent into madness. Another collapse highlighted by Williams is the idea of the "macho-male," which extends to homophobia. Stanley is obviously Williams' characterization of this type of personality, and it is his brutality and chauvinism that lead Blanche to sink completely into the depths of insanity. By raping Blanche, Stanley is not only exerting his physical power over this disruptive woman in his life, but is attempting to show the world (and himself) that he is not a homosexual. In the character of Stella, the reader's primary reaction is to support and identify with her, but in reality she represents the type of person who has given up on the ideals she once knew and has, in a sense, joined forces with the enemy. She deserted Blanche at Belle Reve and has now settled for mediocrity. By the end of the play, our sympathies lie with Blanche because she was searching the world for security and ended up alone and mad.

The Capital Asset Pricing Model (CAPM) Essay Example | Topics and Well Written Essays - 1250 words

The Capital Asset Pricing Model (CAPM) - Essay Example However lending has an interest rate attached to it. In the open market, it is also assumed that traders have all relevant information rates of stocks and other co-variances. Traders in an open market are also assumed to be rationale about being risk averse and all investors have same assets to choose from given all information concerning the assets and same decision methods are applied (Burton, 1998). This brings us to the concept of the capital asset pricing model (CAPM). The model is very useful and is widely used in the industry, although it is based on very strong assumptions. This paper will focus on brief theory of arbitrage theory of the CAPM model, main theories behind this model and their critique. First, the model is quite useful as it focuses on determining the required rate of return appropriate for a company’s assets. The model requires various firms to have a portfolio that is well diversified, as long as the risks prone to the assets cannot be diversified (Brealey, et al 2009). Practically, most companies utilize CAPM model to determine the price of a security or a portfolio. In this case, a security market line that defines the relationship existing between the beta and expected rate of return of an asset is utilized. The line also enables firms to calculate a ratio that equates an asset’s rewards to its risks. It is also through the model that firms are able to determine the rate at which an asset’s cash inflows expected to be generated in future should be discounted. This takes into account the cash inflows in relation to the risks existing in the market. The arbitrage model was an alternative to the means variance capital asset pricing. Currently, the model has become a crucial tool in explaining the phenomenon mostly observed in the capital markets that deal with risky assets. One assumption of the capital asset pricing model is the assumption of normality in returns. It is from this assumption that the linear elation stipulated above originates. The assumption has had critique since theoretically, there does not exist guarantee to such efficiency. However, there is restrictiveness that underlie the mean variance model; therefore being the evidence of the existence of the linear relationship between risks and returns. This led to the popularity of the model. It was until later that Ross introduced a new model that would yield better results when pricing risky assets. The arbitrage model would hold both in equilibrium and all sorts of disequilibria unlike the mean variance analysis. However, there are some weaknesses in relation to this theory. For instance, when dealing with the number of assets, as assets increase, their r eturns are also expected to increase. This will result to an increase in risk aversion to investors. The arbitrage model has the law of large numbers where the noise term becomes negligible as the number of assets expands. Where the degree of risk aversion increases with the increase in the number of assets, the two effects cancels out, leaving the noise term to have a persistent effect on the pricing decision. In developing the arbitrage theory, several assumptions were put into consideration. First is the assumption of limitations on liability. It is assumed that there exists at least one asset which has a limited liability. This means that there are some bound per unit to the losses for which an investor is liable. The second assumption was based on the homogeneity of expectations. All the investors hold the same expectations, since all have the same assets, information and are risk averse. There also exists at least o

The case for christ (student edition) - Essay Example His Divinity was evidenced by His resurrection from the dead and ascension to heaven. To ask the reliability of Jesus Christ is also to ask the historical accuracy and competence of the Holy Bible because it is the source of our information about Jesus Christ. For academic discussion, it may be necessary to cross reference the existence of Jesus Christ from other sources other than the Bible itself. Jesus Christ was recognized to have existed by early historians such as Tacitus, the first century Roman historian who is touted to be the most credible historian of the ancient world. In his historical recordings, â€Å"Christians† (derived from Christus, the Latin equivalent for Christ) was already mentioned in an unflattering way considering that he is a Roman. He mentioned that a certain superstitious â€Å"Christian† or â€Å"Christus† existed during the reign of Tiberius and suffered under Pontius Pilate. In the same breadth, the legendary Jewish historian also made an account of Jesus Christ. In his â€Å"Antiquities†, he mentioned that there was a â€Å"Christ† who is a brother of James. Again, he referred Jesus Christ in an unflattering way considering he is a Jew: â€Å"Now there was about this time Jesus, a wise man, if it be lawful to call him a man. For he was one who wrought surprising feats....He was [the] Christ...he appeared to them alive again the third day, as the divine prophets had foretold these and ten thousand other wonderful things concerning him.† One version reads, â€Å"At this time there was a wise man named Jesus. His conduct was good and [he] was known to be virtuous. And many people from among the Jews and the other nations became his disciples. Pilate condemned him to be crucified and to die. But those who became his disciples did not abandon his discipleship. They reported that he had appeared to them three days after his crucifixion, and that he was alive; accordingly he was perhaps the Messiah, concerning whom the
