CAPM - Essay Example The CAPM presents partial equilibrium model where agents consider the risk free returns and the probability distributions of the future returns on risky assets as being exogenous. In this paper, I seek to give an in-depth understanding of this model by delving into the logic behind it, exploring critiques levelled against it, and explaining why it is still the model of choice in financial analysis. Finally, I give practical examples of its practical application that show evidence of its usefulness and continued use to date. The CAPM is built on the portfolio model that Harry Markowitz (1959) developed. In the model, a portfolio is selected by an investor at time t-1 which at t produces a stochastic return. Investors are assumed to be risk averse and, in their choosing among portfolios, care is only taken on the mean and the variance of their single-period investment return. This results in investors choosing â€Å"mean-variance-efficient† portfolios, the portfolios in this case 1) given variance, maximizes returns and 2) given expected returns, minimize portfolio return variance. For this, the approach is referred to as mean-variance model. An algebraic condition is provided by the model on asset weights in portfolios that are mean-variant-efficient. This algebraic statement is turned by the CAPM into a prediction that is testable about the connection between expected returns and risk through identification of an efficient portfolio if asset prices should clear all the assets off the market. To identify a mean-variant-efficient portfolio, Sharpe and Lintner added two crucial assumptions. The first one is complete agreement: taking asset prices to clear the market at t-1, it is agreed by investors that asset joint distribution returns from t-1 to t. This distribution is taken to be the true distribution, i.e. it provides the distribution giving returns that we employ in testing the model. Secondly, there is risk-free rate

The society and community Essay Example for Free

The society and community Essay Once again, this reason leads the two characters to artificial creation and problems for society. The need for perfection shown by both Frankenstein and Swinton in the books is another reason that drives them to create artificial life. Frankenstein wants to rid the world of disease, and Swinton wishes to continue the illusion of a perfect world in order for his products to continue to sell. This need for perfection backfires considerably. For example, the creature in Frankenstein is far from physically perfect, therefore he gets shunned by society, which is one of the contributing factors to his murders: Am I to be thought the only criminal when all human kind sinned against me? Why do you not hate Felix who drove his friend from his door with contumely? Why do you not execrate the rustic who sought to destroy the saviour of his child? Nay, these are virtuous and immaculate beings! I, the miserable and the abandoned, am an abortion, to be spurned at, and kicked and trampled on. Says the creature when considering his position. This shunning leads to the creature feeling jealous and angry, not to mention self-critical: accursed creator! Why did you form a monster so hideous that even you turned from me in disgust? God, in pity made man beautiful and alluring, after his own image; but my form is a filthy type of yours. Which in turn provokes him into the murders: when I became fully convinced that I was in reality the monster that I am, I was filled with the bitterest sensations of despondence and mortification. Therefore, the need for perfection is a way in which science has negative affects on individuals in society. However, Frankensteins need for perfection is lost at some stages during the novel. For example, Frankensteins shunning of his creation is far from perfect. This is another way in which science has a negative effect on society. For example, the shunning of the creation leads the creation to the murders of Frankensteins nearest and dearest in order for retribution of his abandonment. For example: and what was I? Of my creation and creator I was absolutely ignorant; but I knew that I possessed no money, no friends, no kind of property. This point is also apparent in Supertoys by the rejection of malfunctioning units. For example, the butler in the Swinton household breaks down and David says Throw it away, and well get a new one. This shows the need for perfection in the world and the throwaway attitude that is apparent. This has consequences in that it takes away peoples bare humanity. For example, David is thrown to the reject world ultimately although he was a person who could have been loved. A contributing factor that provokes the characters into furthering science is the families behind the characters. Frankensteins family encourages him to further his knowledge of alchemy, which is linked to artificial creation. Frankenstein also creates the monster because he wants a companion: No father could claim the gratitude of his child so completely as I should deserve theirs. which is linked into the loneliness of the world in Supertoys. In Supertoys, David, has no real family after his creation, this is another problem that is caused by science, and directly relevant to the creation of artificial intelligence that is not loved as though flesh and blood would be. This aspect is linked to the need for love shown by many characters in both stories. Frankenstein, his monster, David, Henry and certainly Monica all show how much they need love. For example: He loves you says Teddy regarding Davids affection for Monica. This need for love drives certain characters to create artificial life, to fill a void. This may be because of unfelt love from their families. For example, Frankenstein begins to feel disjointed from his family after moving to university. The consequence of the need for love is the creation of artificial life, which then in turn needs to be loved. However, in both novels, the artificial life form is not loved. This is what creates the negative affects on society. Another way in which science has a negative effect on individuals in society is the effect the creations have on the creators. For example, throughout Frankenstein, Frankenstein is afraid of his creation and what he might do. Frankenstein cannot care for his creation and spends his whole life in fear. For a large part of his life Frankenstein is forced to follow his creation, in a vain attempt to banish him from society due to the problems he is causing. This pursuit eventually kills him. This can be blamed on himself easily, for he is the one who used science irresponsibly and the consequences backfired upon him. However, this is still a negative effect on society caused by science. Similarly, Henry, eventually, labours to reacquaint himself with David. This comes about after his sense of guilt after abandoning his child. However, these psychological problems are not as important as the prejudices that the new technology brings forward, particularly in Supertoys. This can be explained further by saying that the humans in the artificial world are prejudiced towards the perfect world, and perfect people. What would happen if somebody came along who wasnt perfect? For example, David. David was imperfect in that he was an android and technically he was malfunctioning. Because of this, he was thrown on the scrap heap. This is a problem caused by technology, because it created the prejudices by creating a world where everything is perfect and seamless, nothing is real. Overall, the main scourges of the societies in both books are the artificial creatures and therefore, the creators of these monsters. The creation in Frankenstein shows how science can be used irresponsibly to have negative effects on individuals in society through tactical murder and destruction. The creations in Supertoys show how science can have a negative effect on society by creating social divides, a superficial, prejudiced, fake, lonely, ignorant, arrogant, selfish, inconsiderate, narrow-minded and insecure world in which nothing is solid. The books can be linked to Genesis and Paradise Lost in that they all involve creation, that was well intended but did not turn out as expected. In all four novels the creation was given a world, or habitat, but either they abused it, or inadvertently caused suffering for other members of the community. The authors use the characters of Frankensteins monster and David accompanied by the society and community by the two worlds of the two novels to show how science can be used irresponsibly to have negative effects on society and the individuals within it.

Exemplification Essay: Cruising Should be Banned -- Exemplification Ess

Most of us have enjoyed "cruising" sometime in our lives. For many, it was one of our favorite pastimes. If you lived in the "American Graffiti" era, it was the in thing of to do. I remember when cruising was a popular activity on Main Street in Mesa for many years, until it was banned a few years ago. Now the controversy is over whether to ban cruising on Central Avenue in Phoenix. City officials are trying to reroute the weekend riders to Washington and Jefferson streets. Although cruising may be enjoyable to quite a few teenagers, there is no positive purpose for it. The negative effects of cruising outweigh the reasons for it by far. Cruising should be banned altogether because cruisers have proven to be very loud, dangerous, and a contributor to our pollution problem. I have sympathy for those who live near Central Avenue. The weekends are very noisy in this vicinity. For example, some of the stereos blasting away could accommodate a rock concert. The base volume coming out of these speakers is felt in your heart as you drive along Central...

Snakes, Facts and Falsehoods :: essays research papers fc

  Ã‚  Ã‚  Ã‚  Ã‚  Hesson, 2   Ã‚  Ã‚  Ã‚  Ã‚  With its long slender body the snake is probably the funniest shaped creature you will ever encounter. There are many benefits regarding this wonderful reptile that make it a high asset to the world. It has been said that people are always afraid of what is different, afraid of what they do not know. Many of the rumored questions can be easily dispelled. From questions like what is a Thamnophis sirtalis, to where the extracting organs are located. First, let us dispel any of the rumors that are around about these guys. Despite popular belief, the snake does not swallow there young to protect them from harm; the stomach would immediately start to digest them. This myth came around from fear and adrenaline, but snakes cannot crawl faster than a human can run. The tongue of the snake is not a stinger, but actually a sensory organ. In addition, snakes are not slimy, because they do not secrete any kind of oil. Now that we have started uncovering the truth about these reptiles, we can start with some facts.   Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  In the world today, there are about 2,500 known species of snakes belonging to more than ten families. In the U.S., there are about 127 species, with thirty-eight species found within the U.S. (including five venomous Hesson, 3 ones). Most people wonder what will happen to them if they do happen to encounter a snake. Will I get bitten, is it venomous, will I die, is someone going to have to suck the poison out of the wound, is it trying to kill me, should I try to kill him? A lot of things are happening at this point, more than likely the snake is just trying to defend itself. In addition, it has all the right to do so. First, you disrupted the snake, it did not disrupt you. How would you feel if A five to six foot thing with two legs and hair growing on it almost stepped on you and you were a only a half foot off the ground, you would be pretty shocked. More than likely, the snake is harmless. If by chance the snake is a venomous or dangerous snake just simply stop, and walk slowly away from it. Do not threaten it or try to kill it, just back away. With all this talk about confrontation and how to avoid the snake, it would make sense to mention what to stay on the look out for.

Advances in technology Essay

Because of advances in technology, this world is becoming more efficient and saving us money in the long-run with fuel, electricity, communication, etc. The social lifestyle of an individual involves technology in some way. Technology has become a necessity in these modern days and it is going to become more advanced as time goes on. With these advances in technology, the social lifestyles of individuals can be simpler. Technology moves our world forward into a new and advanced era. Without technology, we would all be stuck in the same time as our ancestors. Technology is a very good thing for people anywhere and everywhere, no matter how old, it helps us in every aspect of our daily lives, and it is a thing that cannot be lived without. Technology has many branches and levels, from cell phones to the internet and even for medical purposes. However, cell phones and the internet have taken the main role in changing our society. I find it truly amazing that a person from China is able to talk to a person from the United States, all through the internet. Programs such as facebook make finding an old childhood friend extremely easy, all that is to be done is type in their name. The advantages of technology include better health facilities due to increased disease diagnosis using technology and faster as well as more accurate business results and solutions through technology. Technology has also enabled the automation of manual work thus saving time and money. It has boosted the entertainment through games and computer programs as well as increase in economy growth due to faster and easier business. Without technology in our lives, our world we be a very different place. Not only does technology provide us with a new and improved way to communicate, is gives us new and exciting ways to research and get ideas out to the world faster. Technology is only going to get better and better as each day progresses and with the appropriate efforts and integrating it into the classroom will enhance education forever. Our advance in technology has and always will be a good thing that will always benefit our world. People’s lives are becoming simpler.

A systematic process Essays

A systematic process Essays A systematic process Essay A systematic process Essay Definitions of research vary from person to person and hence almost every generalized definition has faced criticism from some or the other quarters. The exact definition does not have any consensus among the various theorists (Owojori, 2005). However, a basic definition of research can be as follows: â€Å"a systematic process of discovery and advancement of human knowledge† (Gratton, Jones, 2003, pp. 4). According to Leedy (1985) and Walliman (2001), there are many characteristics of research which help to make the term more clear, such as: it is generated by a specific hypothesis or question, it follows a specific plan or procedure, it requires arguments to support conclusions, it is reiterative etc (as cited in Gratton, Jones, 2003, pp. 5). This chapter describes the notions of the research methodology ensuring that the research is planned and executed systematically. The research philosophy, research design, data collection, sampling group selection and limitation and bias of the research method are pinpointed as the core issues. The chapter also details the research strategies used for ascertaining the research questions and served as a prelude to the analysis chapter of the research.

Deceitful Relationships in the Secret Agent Essay Example

Deceitful Relationships in the Secret Agent Essay Example Deceitful Relationships in the Secret Agent Paper Deceitful Relationships in the Secret Agent Paper The Secret Agent was written by Joseph Conrad and published in 1908. It’s a classic novel based on actual events: the attempt to blow up the Greenwich Observatory in 1984. This fictionalized tale revolves around Mr. Verloc, a spy for his home country of France while living and working in London, Mr. Verloc’s wife, Winnie, a devoted wife and lives her life caring for her young brother, and Stevie, Winnie’s simple-minded brother who manages to get involved with Mr. Verloc’s dangerous politics. The family relationships in this novel, particularly Winnies devotion to her brother Stevie, are quite strong and relevant to the events of the story. The novel seems to be mostly about Winnie, though she appears to only be a minor character throughout the majority of the story. Winnie is the injured party when the scheme to blow up the Greenwich Observatory goes disastrously wrong, though the plan was engineered to save Mr. Verloc from the possibility of death. In a way, Mr. Verloc and Winnie are almost paralleled to one another in the story, both living behind secrets. While reading the novel, Winnie and Mr. Verloc’s relationship seemed odd and unfamiliar. Chapter VIII in The Secret Agent reveals a passage that makes the reader consider Winnie and Mr. Verloc to be strangers to one another: [t]his head arranged for the night, those ample shoulders, had an aspect of familiar sacredness- the sacredness of domestic peace. She moved not, massive and shapeless like a recumbent statue in the rough; he remembered her wide-open eyes looking into the empty room. She was mysterious, with the mysteriousness of living beings. (Conrad 148) The imagery in the passage seems cold, and lacking the passion that a man would use to describe his wife laying in bed next to him. By calling Winnie sacred, Conrad does add a little warmth, because unlike Winnie, Mr. Verloc does love her, but she is also described as mysterious. Winnie and Mr. Verloc have been married for seven years and the fact that she can still be described as mysterious is unusual. Lying in bed together at night is a very intimate moment between two people, and the passage portrays Winnie as being a statue, not moving at all. When in a comfortable marriage, the husband and wife should be able to move freely and talk because it is their time to be alone with one another, but instead Winnie is compared to a statue that is lying down, the imagery in the passage compares Winnie to a figure made of stone. There are other images in the novel where Winnie is completely still, and maybe not directly being called a statue, she acts as one, â€Å"[s]he remained mysteriously still† (Conrad 215) or: a white-hot iron drawn across her eyes; at the same time her heart, hardened and chilled into a lump of ice, kept her body in an inward shudder, set her features into a frozen, contemplative immobility addressed to a whitewashed wall with no writing on it. (Conrad 199) The passage shows that Mr. Verloc and Winnie have not completely opened themselves up to one another, hiding behind secrets. Mr. Verloc hides from Winnie that he is a secret agent working for the French Embassy, and Winnie puts on a front for her husband as a devoted wife so she and her brother, Stevie, can live with financial security. The passage shows the reader just how little Winnie is emotionally invested in her marriage. Winnie appears to an outsider, such as Comrade Ossipon, to be a devoted wife to Mr. Verloc, but in reality she has devoted her entire life to her brother, first protecting the poor boy from his own abusive father, then caring for him when their mother became disabled, and finally marrying Mr. Verloc with the intention that Stevie would always be cared for and not have to work. Winnie has given up freedom and love for her brother and thrown all her trust on to this man, who has a secret life that he has refused to disclose to her. Winnie and Mr. Verloc each hide behind a big secret, which stands in the way of their marriage. They are parallel to one another through their deceit. Both characters are morally corrupt, Mr. Verloc is in many ways self-deceived, since he does not admit to himself how grimy his methods of making a living are, and it seems that he even wanted to be rid of the mentally deficient Stevie with his lack of sympathy for Winnie, and Winnie allows herself to be sexually exploited by marrying Mr. Verloc, whom she does not love, but does it for the sake of Stevie and her mother, and by so carelessly throwing herself at the feet of Comrade Ossipon near the end of the novel. The excerpt shows the reader that Mr. Verloc and Winnie are almost strangers in this story by calling her mysterious, but then the narrator takes it a step further by saying she is mysterious, â€Å"with the mysteriousness of living beings† (Conrad 148). The description of Winnie from Mr. Verloc’s point of view seems very general and vague, not a loving, meaningful, or even familiar depiction of Winnie. But it is not the only time that Winnie is thought of as being mysterious, â€Å"Mrs. Verloc sat still under her black veil, in her own house, like a masked and mysterious visitor of impenetrable intentions† (Conrad 211). Even in her own house, Winnie is somewhat of a mysterious visitor, and Mr. Verloc is not able to relate to his wife, especially after she finds out the truth of Stevie’s death. It is obvious Mr. Verloc does not know Winnie’s true self by the sheer fact that he thinks he’s doing Winnie a favor by sparing his own life and letting Stevie be in control of the bomb, and this shows through Mr. Verloc’s persistent defense of his actions to his wife Winnie, â€Å"‘[d]o be reasonable, Winnie. What would it have been if you had lost me? ’† (Conrad 193). When Mr. Verloc asks Winnie that question, he must be assuming that Winnie would be more sorrowful had he died instead of Stevie. Mr. Verloc is clearly unaware of Winnie’s intentions for their marriage and just how much she truly cared about Stevie. Mr. Verloc and Winnie’s deceit ultimately brought them to their deaths at the end of the novel. Both suffering from moral corruption and a loveless marriage, Mr. Verloc and Winnie were paralleled through their secrets from one another. Conrad, Joseph. The Secret Agent.
