Speech Analysis -- essays research papers

This is the speech delivered by President Bill Clinton at the annual White House prayer breakfast on Friday, September 11, 1998, to an audience of more than 100 ministers, priests and other religious leaders. First Lady Hillary Rodham Clinton was also in attendance. The speech, written in long hand by the president, was delivered at the beginning of a day of tremendous political and personal turmoil surrounding the publication of the first report to Congress by Independent Counsel Ken Starr. The Starr Report, published on the Internet about 2 p.m. on Friday, laid the grounds for possible impeachment of the president, accusing Clinton of perjury, obstruction of justice and other offenses in connection with his sexual affair with former White House intern Monica Lewinsky. If the President did in fact write this address himself, I am very impressed with his communication skills. Repeatedly throughout the speech, Clinton appeals to the forgiving nature of all those listening. Within the first few opening sentences, the President manages to gain sympathy by saying that he â€Å"was up rather late thinking and praying about what he ought to say†. Through a combination of this and stating that he himself wrote the speech, he has already gained support form his audience – which can set the tone for how they will react to the remainder of what he has to say.   Ã‚  Ã‚  Ã‚  Ã‚  President Clinton then continues his attempt to put himself on the same ground as the American publi...

Diathesis Stress Model

Diathesis- This is the genetic predisposition which the Genain children expressed through their father. Mr. Genain had various fears and obsessions such as patrolling the house because he was worried of a break in, forms of paranoia. Since paranoia is a symptom of schizophrenia it is likely that Mr. Genain was schizophrenic and he passed this gene onto the children. Later on, his actions created stress that triggered the schizophrenia in his children. Stress: Nora and Myra were considered the more superior set of twins and therefore were able to function better than Iris and Hester. This categorization is probably one of the first stressors that caused Iris and Hester to suffer the worst from the disorder. A stress that affected all of the children and helped trigger the disorder was Mr. Genain’s insistence on watching the girls dress and undress. Furthermore, his molestation of two of the girls made them more likely to develop schizophrenia. Part of the reason Nora was not as successful as Myra was because she was her father’s favorite sexual target which added more stress to her life. Another stressor that hurt Iris and Hester was when their parents had their clitoris’s were circumcised. Also, since Iris, Nora, and Myra began deteriorating after a man made improper advances this proves that stress played a prominent role in the signaling of schizophrenia. Myra was able to be the most functioning individual because she was her parent’s favorite and received the least objectionable attention, and therefore had the least amount of stress in her life.

Discuss the scope of mixed branding Essay

Ans. Definition: Mixed Branding is where a firm markets products under its own name and that of the reseller(s) because the segment attracted to the reseller is different than its own market. Eg. The company sells its Elizabeth Arden brand through department stores and a line of skincare products at Wal-Mart with the â€Å"Skinsimple† brand name. Stratergies: When promoting a brand, companies sometimes choose to follow a multiproduct branding strategy, similar to automakers Ford and Toyota. In this regard, a company’s name is an umbrella brand for all its products. Coca-Cola, Apple and Intel have focused their energies on branding their corporate names and images rather than individual products. Grocery chains and big-box retailers use private-label branding to attract value-conscious customers. Advantages: Companies use branding to differentiate their products based on value, quality and other attributes. A positive brand image creates a halo effect that affects existing products and makes it easier to introduce new products. The â€Å"Intel Inside† campaign, for example, was designed to brand all Intel microprocessors as high-performance and high-quality products. Apple has followed a somewhat different route because it relies on its corporate name and unique product brands. A mixed-branding strategy can leverage a company’s reputation for innovation to carve out profitable market niches, such as Apple’s Mac computers for graphics-intensive operations, while developing entirely new markets, examples of which would be iPods and iPads. Kraft consumers know they are getting a quality food product, which makes it easier and more cost-effective for Kraft to introduce and gain consumer acceptance for new products. Disadvantages: The main disadvantage of branding is the high advertising and related public relations costs. Establishing a local or international brand requires years of sustained advertising, high levels of quality and exceptional customer service. A brand image and reputation cannot be established in a few weeks. Companies must continue their promotions even during economic downturns or when sales stagnate, because if they do not, competitors might fill the void and be in a better position when the economy turns around. These expenditures can reduce margins, especially if sales volumes are being affected by price competition or changing customer preferences. Also, there is the risk that poor customer service by wholesalers or retailers in the distribution channel might reflect poorly on the brand itself. Manufacturing issues that lead to product recalls, such as Toyota’s well-publicized problems with brakes from 2009 to 2011, can also affect a brand’s image, which usually requires additional expenditures to repair.

Retrenchment Strategy Essay

Since the beginning of the US financial crisis in 2007, regulators in the United States and Europe have been frustrated by the difficulty in identifying the risk exposures at the largest and most levered financial institutions. Yet, at the time, it was unclear how such data might have been used to make the financial system safer. This paper is an attempt to show simple ways in which this information can be used to understand how deleveraging scenarios could play out. To do so the authors develop and test a model to analyze financial sector stability under different configurations of leverage and risk exposure across banks. They then apply the model to the largest financial institutions in Europe, focusing on banks’ exposure to sovereign bonds and using the model to evaluate a number of policy proposals to reduce systemic risk. When analyzing the European banks in 2011, they show how a policy of targeted equity injections, if distributed appropriately across the most systemic banks, can significantly reduce systemic risk. The approach in this paper fits into, and contributes to, a growing literature on systemic risk. Key concepts include: * This model can simulate the outcome of various policies to reduce fire sale spillovers in the midst of a crisis. * Size caps, or forced mergers among the most exposed banks, do not reduce systemic risk very much. * However, modest equity injections, if distributed appropriately between the most systemic banks, can cut the vulnerability of the banking sector to deleveraging by more than half. * The model can be adapted to monitor vulnerability on a dynamic basis using factor exposures. About Faculty in this Article: Robin Greenwood is a Professor in the Finance unit at Harvard Business School. * Author Abstract When a bank experiences a negative shock to its equity, one way to return to target leverage is to sell assets. If asset sales occur at depressed prices, then one bank’s sales may impact other banks with common exposures, resulting in contagion. We propose a simple framework that accounts for how this effect adds up across the banking sector. Our framework explains how the distribution of bank leverage and risk exposures contributes to a form of systemic risk. We compute bank exposures to system-wide deleveraging, as well as the spillover of a single bank’s deleveraging onto other banks. We show how our model can be used to evaluate a variety of crisis interventions, such as mergers of good and bad banks and equity injections. We apply the framework to European banks vulnerable to sovereign risk in 2010 and 2011.

The Role of Technology in Quality Education

THE ROLE OF TECHNOLOGY IN QUALITY EDUCATION Dr. R. Sivakumar Assistant Professor Department of Education Annamalai University Introduction Quality education is a universal goal. It is common to hear arguments that instructional technology will be the key to educational quality as we enter the new millennium. Investment in educational technology is urged upon policy-makers as the path to educational quality.In fact, enthusiasts for educational technology argue that quality has and will continue to increase rapidly, creating a â€Å"new educational culture† Whatever problems exist are seen as ones which can be handled through better administrative and technological planning – that is, technology believers perceive no intrinsic obstacles to total quality assurance using information technology in higher education. Other voices question educational technology as a panacea.The problems associated with technology in the college classroom in terms of issues such as poorly funct ioning equipment, over-promotion of technology-based learning to students, and lack of quality in courses delivered by technology. Educational technology who say students choosing online courses are not getting the education they pay for, and question whether universities should be providing such instruction.The American Federation of Teachers and other faculty organizations have also raised serious cautions about web-based education and have even gone on strike over it. Technology in Quality Education In response to growing criticism of the recent, rapid, unregulated growth of distance education, a number of recognized higher education organizations have formulated quality standards and guidelines. The principles have been endorsed by a number of higher education governing and policymaking bodies in the world, as well as by the regional accrediting community.The core assumption of these guidelines is that, â€Å"The institution's programs holding specialized accreditation meet the same requirements when offered electronically. † Since these guidelines are a widely-accepted definition of â€Å"quality† as applied to online education, they are quoted below: * Each program of study results in learning outcomes appropriate to the rigor and breadth of the degree or certificate awarded. * An electronically offered degree or certificate program is coherent and complete. The program provides for appropriate real-time or delayed interaction between faculty and students and among students. * Qualified faculty provides appropriate oversight of the program electronically offered. * The program is consistent with the institution's role and mission. * Review and approval processes ensure the appropriateness of the technology being used to meet the program's objectives. * The program provides faculty support services specifically related to teaching via an electronic system. The program provides training for faculty who teach via the use of technology. * The p rogram ensures that appropriate learning resources are available to students. * The program provides students with clear, complete, and timely information on the curriculum, course and degree requirements, nature of faculty/student interaction, assumptions about technological competence and skills, technical equipment requirements, availability of academic support services and financial aid resources, and costs and payment policies. Enrolled students have reasonable and adequate access to the range of student services appropriate to support their learning. * Accepted students have the background, knowledge, and technical skills needed to undertake the program. * Advertising, recruiting, and admissions materials clearly and accurately represent the program and the services available. * Policies for faculty evaluation include appropriate consideration of teaching and scholarly activities related to electronically offered programs. The institution demonstrates a commitment to ongoing s upport, both financial and technical, and to continuation of the program for a period sufficient to enable students to complete a degree/certificate. * The institution evaluates the program's educational effectiveness, including assessments of student learning outcomes, student retention, and student and faculty satisfaction. Students have access to such program evaluation data. * The institution provides for assessment and documentation of student achievement in each course and at completion of the program.Empowerment in Online Education Technology enthusiasts believe online methods will liberate learning from the confines of the lecture hall, but it can be difficult to reconcile distance education with empowerment of students and faculty. One common tactic where empowerment is a goal of distance education at all is to keep guidelines-from-on-high to a minimum and to rely on local autonomy. Recent position, quality assurance in distance education, however, have noted with dismay th e drift toward standards imposed from above. Remote learning† would simply lead to students staying at home in front of computer keyboards instead of being taught in a school environment. â€Å"This is way out of touch with the expectations of parents who want their children to develop both socially with other students and educationally under the guidance of qualified teachers†. Online Education and Community The â€Å"community of scholars† was central to the traditional concept of higher education.The thrust of online education advocacy is to broaden the concept of community in non-traditional ways, particularly through partnership with or even contracting out to the business community. Educational institutions in all advanced countries encounter strong incentives for private sector partnering since the high costs of multimedia-rich online curricula are often beyond what a single local college can afford. In the traditional â€Å"community of scholars† t he student was mentored as an apprentice and eventually became a co-investigator in research and creative activity.Advocates of online education argue that this notion of academic community will be enhanced through the wonders of technology. Online education is frequently the province of the campus adult education unit, not the academic departments. Often instructor participation is an overload, potentially seducing faculty away from research. Administrators seek to use online education â€Å"to increase academic productivity† and, as discussed elsewhere in this essay, seek cost savings in an atmosphere unfavorable to the research function.Moreover, most institutions have found that online education is intrinsically very demanding of valuable faculty time, which can also take away from research. On the student side, the social distance inherent in online education seems to make students want clear, precise, objectives-oriented curricula which may represent a narrowing of educ ation, and may make them unlikely candidates for collegial work on faculty research projects. The reality of online education is that it favors a transition from traditional notions of academic community toward a much narrower, transactions-based model.Online Education and Learning Autonomy Online education faces the paradox that it is best undertaken by students with strong autonomous learning skills, yet at the same time the disconnectedness of students from teachers seems correlated with insistent student demands for clearly structured learning assignments and schedules. Students frequently feel the need for ongoing communication with their instructor. A commonly expressed student need is that for very clearly and explicitly articulated course learning objectives.That is, online pedagogy seems more associated with â€Å"cyber distance† than with â€Å"virtual community,† and students quickly become motivated to seek to overcome cyber distance through increased cours e structure, reducing learning autonomy. Online education is part of a cost reduction effort, requiring human resources to be stretched to cover more credit hours, faculty resignation to the training mentality of outcome-based evaluation is all but assured except, of course, in environments which do not even bother to attempt to enforce quality assurance standards. Online Education and Critical ThinkingOnline education can handle instruction-to-facts more easily; drill-and-practice is the forte of computer methods. Ironically, in contrast, traditional education with its supposedly uncreative lecture hall methods has prided itself in its ability to inculcate critical thinking skills. Distance education administrators are aware that critical thinking of online methods. Therefore it is not unusual to find that quality assurance standards for online education make reference to student thinking skills, independent learning skills, teamwork and communication skills, and other aspects of c ritical thinking.Moreover, intelligent-agent and workgroup collaboration software often are targeted directly at encouraging critical thinking skills. Critical thinking can be inculcated using technology such as cyber mentoring and video theater. A love-hate relationship exists between online education and critical thinking skill development. Writing assignments are thought to help develop critical thinking and while online methods can enhance collaborative writing, in general online courses are associated with less writing, not more.Socratic discussion with faculty is also thought to inculcate critical thinking, but while online methods in theory could enhance discussion, in reality online courses are associated with far less instructor-oriented discussion. Critical thinking is also thought to be associated with problem-solving going beyond computational mechanics to consideration of complex causal and value systems, but while intelligent tutoring software does exist, the open-ende dness of creating problem-solving together with the asynchronous nature of most online education mean that in practice online courses rarely develop the problem-solving approach.Online Education and Educational Quality In comparing computer-mediated distance education with traditional face-to-face teaching experiences, while distance education increases access to education, one may well find decreases in instructional quality brought about by increased faculty workload, problems of adapting to technology, difficulties with online course management, and related obstacles. By focusing on instruction to learning objectives, as with traditional instruction-to-test approaches, test performance standards are usually met by online courses.Although tested output of electronic education is often on a par with conventional teaching, this does not mean educational quality is unaffected however. Many observers find in typical online education offerings a substantial narrowing of the concept of education to the detriment of students. One of the recurring problems of computer-mediated education is that it is programmed around concrete learning objectives. Conclusion Many educational technology writers, in fact, explicitly argue that quality education using computer methods must be built on a foundation of clearly-defined competency-based curricular objectives.Online education is now arousing academic resistance. The emergence of a two-tier educational system – a more expensive upper tier with sound traditional education supplemented with the benefits of full online access, and a cheaper inferior tier dispensing programmed training which meets objectives far narrower than the traditional goals of liberal education.

A Plot Summary of a Movie About Cuban Refugees in America

A Plot Summary of a Movie About Cuban Refugees in America In 1980, Fidel Castro sent hundreds of thousands of Cubans from his country on rafts to America. Castro not only sent everyday people to America on boats; he used this as a chance to clear out his crowded jail cells. There was an estimated 25,000 former Cuban inmates that arrived in Florida. Tony Montana is one of the masses of criminals sent by Cuba to America. His only chance to get a green card was to kill Rebenga, a former political leader from Cuba. Montana had no trouble executing the former communist leader. Tony moves to Miami and agrees to do a job for a big time cocaine dealer, Frank Lopez. Frank noticed the good job Tony did for him and in turn wants Montana to continue working for him. Lopez sends him to Bolivia to work on a deal with Sosa, their cocaine supplier. While there Tony seizes an opportunity to go into business for himself. Tony shoots his way to the top of a drug crime family, killing both friend and foe alike. Finally after murdering his boss and marrying his bosss girlfriend, hes crowned drug kingpin. Tony starts having legal problems and rather than do time, his supplier Sosa offered to take care of the court case if Tony would take an assassin with him to New York to eliminate one of his enemies. This was the begging of the end for Tony Montana. The man who was supposed to be eliminated had his wife and kids in the car with him. Tony was against killing women and children but the assassin wouldn’t listen to him; so Tony shot him. Tonys decline was caused by his twisted sense of brotherhood. When Sosa learned of this he was furious. He sent a small army of men to Tony’s home to kill him. Tony didn’t go down easy, but in the end he still went down. Drugs in this movie portrayed money and power. Whoever distributed the drugs had control of the others around him who didn’t. The main goal of many characters in this movie was to get people under you so they can do your dirty work. All major characters in this movie were obsessed with money drugs, and women. Tony’s philosophy was: â€Å"First you get the money, then you get the power, and then you get the women. The unhealthy messages about drugs conveyed in this movie suggest that they are a quick way to make cash but can ultimately be someone’s downfall. Tony’s drug control led to other problems. He couldn’t get his money laundered from his normal banker because the more money Tony gave the banker, the higher the interest charge he would receive in return. Tony’s best friend set up a meeting with a different banker; who happened to be an undercover police officer. Drugs are also portrayed as a way to get women. Elvira, the woman of Tony’s obsession, went from one boyfriend to another based on who could supply her cocaine addiction. In one particular scene Frank tells Tony the two key rules to success in the drug business. Rule number one is to â€Å"never underestimate the other guys greed.† Rule number two is to â€Å"never get high on your own supply.† This came back to haunt Tony because later in the movie Frank hired two hitters to take Tony out right during a performance by octavio the clown. Just when octavio was waddling around the stage, the hitters opened fire. Luckily for Tony, they werent great shots. Tony managed to evade them and escaped through the door. Tony knew it was Frank. The only thing to do was to strike back. So, he went right over to Franks. Frank denied any involvement. He said it was the Diaz brothers. Tony wasnt fooled and Frank cracked. He admitted to what he did and knelt down and groveled at Tonys feet. Tony ordered his death. The last scene was the most memorable because Tony had crossed Sosa, the powerful cocaine supplier and Sosa sent his army to execute Tony. Tony was so doped up on cocaine that he took seven or eight shots in the chest and didn’t feel any pain. He made the statement: â€Å"Your bullets can’t hurt me.† It took a shotgun blast in the back to finally kill Tony. Tony’s death was as violent as his life. I would definitely recommend this movie to others, especially if they’re the kind of person who enjoys violent, action-packed movies. was very realistic and shows how a Cuban refugee could have climbed up ladder to become a very powerful drug dealer. This film was very violent and bloody. Compared to some films today, the violence isn’t as bad as people thought it was in 1983. One of my favorite scenes in the movie is when Tony’s friend Angel is getting cut into pieces with a chainsaw. The blood splatters everywhere. The music in this film sometimes seemed lifeless and boring. When you take into consideration that it was made almost eighteen years ago, the music doesn’t sound too bad. I think Frank Lopez’s first rule of how to succeed applies to every aspect of your business life. Because no matter how bad you may want something, there’s always going to be someone else who wants it more than you.
