Alex Sharpes Portfolio Solution Essay - 1231 Words
Context: Alex Sharpe currently invests her childrenââ¬â¢s educational savings in Vanguard 500 Index Fund, which tracks the performance of Samp;P 500 and is passively managed. However, she is now considering switching her investment strategy to a more active one to achieve better outcomes. Hasbro, a toy manufacturer, and Reynolds, a tobacco firm, have come into Sharpeââ¬â¢s sight and she wants to choose one of them and invest a small proportion of equity funds in it. In order to select a more appropriate investment target, the following issues should be taken into consideration by Sharpe: 1) What are the risk-return characteristics of each stock 2) What are the impacts of either stock to the overall risk-return profiles of the equityâ⬠¦show more contentâ⬠¦2. Perform a regression of each stocks monthly returns on the Index returns to compute a beta for each stock. How does this relate to your answer in question 1? Regression analysis of Reynolds and Hasbroââ¬â¢s returns on market indexââ¬â¢s returns shows that Reynolds has a much lower beta coefficient than Hasbro (0.736 compared with 1.42). It is a supporting evidence for our calculation in question 1. Lower beta means that Reynolds is less positively correlated with the market as a whole. So it is obvious that its contribution to overall portfolioââ¬â¢s variance will also be smaller. Take a deeper look at the regression outcome, we found that Intercepts of both stocks have quite large p-value (0.225 for Reynolds and 0.659 for Hasbro). It indicates that those test statistics are not significant enough to reject the null hypothesis that intercept of Reynolds and Hasbro are 0. A more important thing is p-value for beta coefficient. Although Reynoldsââ¬â¢s p-value is 0.0285, meaning that null hypothesis that beta is zero will not be rejected for a level of significance at 1%. However, we normally consider a 5% level of significance, so it is enough to reject null hypothesis and Reynoldsââ¬â¢s beta is really different from 0. For Hasbro, p-value is far small enough to reject null hypothesisShow MoreRelatedAlex Sharpes Portfolio Solution Essay904 Words à |à 4 PagesAlex Sharpeââ¬â¢s Portfolio 1.

The Strange Case Of Dr Jekyll And Hyde, by Robert...
The Strange Case Of Dr Jekyll And Hyde,By Robert Stevenson The Strange Case of Dr. Jekyll and Mr. Hyde, The separation of Jekyll into two beings, Jekyll and Hyde, is an symbol for humankinds conflicting forces of good and evil. These characters bring to life the inner struggle between the two powers of the soul. Jekyll portrays the good side of human nature in this narrative. He is the protagonist of the novel. Dr. Jekyll is an intelligent, tall, and dignified man of late middle age. The people who know him respect him. He is a wealthy man and lives in comfort in a good house with loyal servants, he is the model of the Victorian gentleman, But he has a dark side, Jekyll is not supposed to represent pure good, rather, the wholeâ⬠¦show more contentâ⬠¦Hydes youth and small, distorted stature can be linked to the inactive evil within Jekyll. At first, Jekyll is in complete control of the appearance of Hyde, having him only appear when he so wills. At this point, the good is much stronger and has control over the evil. As the iniquity wit hin Jekyll, begins to be exercised with more regularity, it becomes more powerful. Jekyll loses contact first with his good side and then with his friends. The more he plays at being Hyde the more he is cut off from their good worth. With this newfound clout, Hyde begins to appear without Jekylls indicating. This foreshadows that the evil of the human soul now begins to succeed over the once dominant good. The callous murder of Sir Danvers Carew provides the reader with a sense that cruelty has won complete control over merit. Jekyll is now faced with a question of morality. Should he let the evil reign, or should he repeal the being he has created along with himself. It has become clear to Jekyll that he can no longer go on with this front, and decides that Hyde will soon seize complete control. In an effort to stop this conquest from occurring, Jekyll decides that he will soon turn into Hyde for the last time, he declares his life over and that anything that happens after that point on will not happen to him, as Jekyll will be truly dead to the world.

Working as a Team free essay sample
Theory1. Introduction People form teams to accomplish a shard goal or task and have done so since the beginning of human history. For instance, cavemen building a fire together, students working on a group project, or basketball players playing on the same team, the need for teamwork is becoming greater. Parker (2011) suggests that teamwork is essential for business organizations to achieve success. Nowadays, working efficiently with others in a team is a key skill in order to survive in the competitive world of work. In any global business, certain skills and strategies are needed to incorporate into developing teams to maintain effective outcomes. The range of skills includes motivation, conflict management and team goals. This essay will examine the three mentioned aspects of teamwork that would prepare a person to work effectively in a team environment, supported by two real world examples for each aspect to show how individuals in organizations work successfully as active team players. 2. Body Firstly, motivation is an essential element in team-based workplaces. Workers are not mechanism, when they are asked to do the same tasks repeatedly, they will easily lose their interest or passion for their jobs. Consequently, a good way to keep team membersââ¬â¢ passion is to motivate them. Motivation theory is one of the most vital theories in Human Resource Management. Armstrong (2001, p. 155) explains the motivation theory is applicable in organizations where they motivate their team members to utilize their skills and knowledge. This would aid at surpassing the organizations goals and improve the capability to provide better for their teams. According to a research conducted by Macky and Johnson (2003, p. 82), the result shows that when teams are provided with a satisfactory workplace reflecting each personal necessity and requirement, instead of a higher wage or bonus, members are motivated to work harder and more efficiently. This indicates that using beneficial motivators is becoming more important in nowadays business. In the operation of organizations, examples show motivation plays an important role in achieving success. Howard Schultz, the chief executive officer (CEO) of Google Inc. hich is based in California, considers that the success of the company is to put their employees as the first priority in its offices. According to the official website of Google (2011), the company offers a great range of benefits, including dining facilities, aerobics studios, laundry rooms, massage rooms, haircuts, car wash service and more. He firmly believes that ââ¬Å"appreciation is the best motivationâ⬠, by providing a f un and inspiring workspace, team members are able to work in a positive atmosphere. This means team partners can motivate each other to satisfy their own needs, thus a greater opportunity to offer a higher level of performance (Google, 2011). Schultz is the CEO of Starbucks, an international coffeehouse chain based in Seattle, USA, applies the same principle that employees matter just as much as products do. Michelli (2008) states that Starbucks provides a variety of welfare measures for the Starbucks teams, for instance, accommodation discounts, medical insurance, and vacations. This shows when the company satisfies team membersââ¬â¢ needs, they are encouraged to work towards the same goal and strive for the best for the company. From these two examples, it is clear that therefore motivation can lead team members to provide higher quality of work and increase the profit of the company. Secondly, conflict management is a vital aspect in a high-performance team. Conflict is defined as ââ¬Å"the perceived difference between two or more parties resulting in mutual oppositionâ⬠(Bartol et al, 2008, p. 24). Conflicts are inevitable as different members in teams have different opinions and methods to show their variations (Engleberg, Wynn, 2006, p. 147). Some of the major causes of conflicts are arise from the oppose perspective of membersââ¬â¢ desire, goals, values and beliefs (DeJanasz, Dowd, Schneifer, 2001, p. 243). Conflicts and arguments in teams can rise negative feelings among members such as ââ¬Ëlost sight of team goalââ¬â¢, these feeling s may lead to failure in achieving effective outcomes (Engleberg, Wynn, 2006, p. 48). Therefore, it is important for team members to recognize the effective strategies in dealing with conflicts in order to minimize fighting and hostility. With proper conflict management, workers are able to work productively as a team where differentiality are accepted (Boone, Kurtz, 2010, p. 2). This shows development of conflict management techniques is essential in contemporary business. In any team-based workplace, correct conflict management can enhance the success of organizations can achieve. The CEO of a Houston-based Birkman International Company, Richard Goldman introduced a policy where his team of employees need to attend compulsive communication classes every week in attempt to reduce conflicts arise from misunderstanding when they communicate (Tallia et al, 2006). Goldman considers that overcoming communication barriers can provide outstanding insights with team membersââ¬â¢ thoughts and act (Tallia et al, 2006). This suggests that team members are allowed to work more practically together when conflicts are handled and solved with efficient management skills. Another example is McDonaldââ¬â¢s, the worldââ¬â¢s largest chain of fast food restaurant located internationally. The CEO James A. Skinner believes that by offering training programs, such as McDonaldââ¬â¢s Management Development Program, managers can build a fully understanding of the companyââ¬â¢s policy and the basic skills of manager when working with other people in the McDonaldââ¬â¢s Crew (McDonaldââ¬â¢s, 2011). This enables mangers to deliver a better management performance when dealing with conflicts. As a result, staff can create a harmony team environment and maintain effective achievement. The above two examples indicates that conflict management is crucial in the success of organizations. Lastly, leadership is vital in team-oriented workplaces. Ivancevich Matteson (2002, p. 45) define team leadership as ââ¬Å"the process of influencing others to facilitate the attainment of organizationally relevant goalsâ⬠. Leadership is important as it has been addressed as essential to achievement in teams(Gill, 2006, p. 1). A team leader with distinct leadership skills are able to help members to further the achievement of success. Good leadership skills include clear vision, the ability to spot the difference between team members, bring the team together to work towards the same goal and more (Armstrong, 2009, p. 36). All of these bring positive outcomes in teams. As a result, in nowadays organizations, leadership is one of the most vital aspect to be considered. The positive outcomes that team-based organizations achieve are visible. Carol Baines took over the Baines Company after the death of her husband, the previous owner of the company. She spent her time in the company to familiarize herself with the staff and operations of the company. She then analyzed the companyââ¬â¢s situation and set a powerful set of term goals for the company. With her determined vision and remarkable leadership skill, she created a ââ¬Ëfamily-like atmosphereââ¬â¢ for team members to work in. Members saw the clear goal of the company, thus significant success was achieved by the company (Northouse, 2010, p. 30). Another good leader is Steve Jobs, the CEO of America-based electronic company, Apple, Inc.. His good leadership skills have effectively bring success to the company. His quest for perfection has motivated his team to perform their best work quality. These two example makes it clear that leadership makes a huge different in maintaining effective outcomes of organizations. Conclusion To conclude, this essay has examined three aspects of teamwork that are essential when working effectively with other people in business organizations, namely motivation, conflict management and team goals. It has also provided with real life examples that showed how organizations can incorporate numbers of skills and strategies to create the right team environment. First of all, motivation can create a positive team environment for team members to work effectively together. In addition, proper conflict management can reduce arguments and fights between team members in order to maintain efficient outcomes in organizations. Finally, leadership . Good teamwork certainly is beneficial in the operation of organizations and has become an important aspect to be considered. As s result, organizations should be aware of those aspects and utilize the ability of teams.

Analysis of Hypocrisy in Adventures of Huckleberry Finn free essay sample
The Adventures of Huckleberry Finn, takes place in a time in age where the deficits of society are so intricately interwoven and ignored upon the individuals that make up that society. This results in hypocrisy that constantly plays a crucial part in how Mark Twain depicts the society that participates in such irrational activity. Characters, that Huck and Jim meet as they head for their freedom, which for Jim is slavery, and for Huck is the enslavement through civilization which is ââ¬Å"practicedâ⬠by such a hypocrite society. Both are searching for freedom that is well defined in their own parameters; but are kept under constant hypocrisy in the pursuit to achieve their freedom. However, hypocrisy by a ââ¬Å"civilizedâ⬠society is as dominant in todayââ¬â¢s society as it was in the time that Huck and Jim encountered it. Even though todayââ¬â¢s, hypocrisies take a new shape and form and are interwoven with daily activities.

Although the hypocrisies that are evident in Huckleberry Finn might be in the form of the judge allowing Huckââ¬â¢s father, to keep him in custody, well knowing that he a drunkard would kill Huck to get his money. To the ignorance, of towns people and the nieces who were scammed by the duke and king. Everyone had taken so much self-esteem into the fact that the nieces had accepted the duke and king as their uncles that no one gave a second thought, even when it was publicly announced by Dr. Robinson; as every ââ¬Å"civilizedâ⬠person who knew right from wrong sprang upon the doctor, trying to subdue him. As the greatest hypocrisy that took place in the book, was due to the time period itself; a time of white supremacy and racial prejudice, that took place everywhere, a time of slavery. These individuals who Huck ran away from to avoid being civilized, were themselves uncivilized due to the way they treated slaves who are non-other than human beings as well. Implying the fact that it is impossible for a society who owns and treats slaves as uncivilized people themselves can never be just. While, we see this constantly throughout our society today, as people call others fat, anorexic, sub-standard, not cool, not cute, irrational, and stupid; while they themselves have a bottomless pit of ignorance, leading to their own oblivion. Todayââ¬â¢s society is actually worse than before in the sense that we are not only fed these things as a child; but we have to incorporate it into daily life through the influence of others, such as parents, media, and peers. Making our very existence, self-evident of such a paradox that can only derive from hypocrisy of a so called ââ¬Å"civilizedâ⬠society. As the time Mark Twain had written this novel, many social flaws existed within the fabrics of the community as a whole. The book played a major role within the cultural context of the era due to the fact that Jim, who was a slave and Huck a freeman were able to bond and have such an amazing journey together. Within this journey, Twain had interwoven several moments, that on the surface seemed like a norm at the time, but exploited several social flaws that would have otherwise been dismissed by ignorance. Resulting in a successful message from the author, hopefully allowing one to see at that time in age what horrid activities they take place in on a day to day basis, when viewed upon by another personââ¬â¢s spectacle.

Wildlife of the Great Lakes
Wildlife of the Great Lakes The Great Lakes are a chain of five large, freshwater lakes that are located in central North America, astride the border of Canada and the United States. The Great Lakes include Lake Erie, Lake Huron, Lake Michigan, Lake Ontario, and Lake Superior and together formà the largest group of freshwater lakes on Earth. They are contained within the Great Lakes watershed, a region whose waters discharge into the Saint Lawrence River and, ultimately, the Atlantic Ocean. The Great Lakes cover a total surface area of 95,000 square miles and hold about 5,500 cubic miles of water (approximately 20% of all the worlds fresh water and more than 80% of the fresh water of North America). There are more than 10,000 miles of shoreline that frame the Great Lakes and from west to east, the lakes span more than 750 miles. The Great Lakes formed during the Pleistocene Epoch as the result of the repeated glaciation of the region during the Ice Ages. Glaciers advanced and retreated time and again, gradually carving deep depressions in the Great Lakes River Basin. When the glaciers receded at the end of the last glacial period about 15,000 years ago, the Great Lakes filled with water left behind by the melting ice. The Great Lakes and their surrounding lands encompassà a wide variety of freshwater and terrestrial habitats including coniferous and hardwood forests, freshwater marshes, freshwater wetlands, dunes, grasslands, and prairies.à The Great Lakes region supports a diverse faunaà that includes numerous species of mammals, amphibians, birds, reptiles, and fishes. There are more than 250 species of fishes found in the Great Lakes including Atlantic salmon, bluegill, brook trout, Chinook salmon, Coho salmon, freshwater drum, lake sturgeon, lake trout, lake whitefish, northern pike, rock bass, walleye, white perch, yellow perch, and many others. Native mammals include the black bear, fox, elk, white-tailed deer, moose, beaver, river otter, coyote, gray wolf, Canada lynx, and many others. Bird species native to the Great Lakes include herring gulls, whooping cranes, snowy owls, wood ducks, great blue herons, bald eagles, piping plovers, and much more. The Great Lakes have suffered greatly the effects of introduced (non-native) species during the past two hundred years. Non-native animal species such as zebra mussels, quagga mussels, sea lampreys, alewives, Asian carps, and many others have greatly altered the Great Lakes ecosystem. The most recent non-native animal to have been recorded in the Great Lakes is the spiny water flea, a crustacean native to the seas of the Middle East that are now quickly populating Lake Ontario. Introduced species compete with native species for food and habitat and can also More than 180 non-native species have entered the Great Lakes since the latter part of the 19th century. Many of the introduced species have been transported into the Great Lakes in the ballast water of ships, but other species such as the Asian carp, have invaded the lakes by swimming through the man-made channels and locks that now connect the Lake Michigan to the Mississippi River. Key Characteristics The following are the key characteristics of the Great Lakes: the largest group of freshwater lakes on Earthaccount for 20% of all the worlds fresh wateraccount for more than 80% of the fresh water of North Americaintroduced species have greatly altered the Great Lakes ecosystemsupports more than 3,500 species of plants and animals Animals of the Great Lakes Some of the animals that inhabit the Great Lakes include: Lake whitefish (Coregonus clupeaformis) - The lake whitefish is a species of freshwater fish that belongs to the salmon family.
