Evalutating country risk analysis Essay Example | Topics and Well Written Essays - 1000 words

Evalutating country risk analysis - Essay Example This inter mix of factors creates a complexity in understanding and application of CRA. (Meldrum: 2000). The measures used for risk evaluation may differ based on the experience and judgement of analysts. These may employ a number of common points initially and then lead to detailed discussion of specific issues affecting a specific sphere of interest. Thus a combination of actual and potential imbalances are calculated to apply to a broad investment category.These decisions are judgemental and hence may have limited universal application across the board. (Meldrum: 2000). Broadly the measures applied by the Political Risk Services' International Country Risk Guide (ICRG) for CRA include political, economic and financial risk. The ICRG also calculates a composite risk which is generally evolved from these base indices. A final measure which some analysts examine with reference to CRA is Institutional Investor's country credit ratings. Thus it would be seen that information is defined in a number of ways. (Erb.Harvey.Tadas:1996). Another problem in CRA is limited availability of historical data in emerging economies. This increases the uncertainty of future prediction. (Damodaran: 2004). Since risk implies identification of a well defined event from a large number of observations which is amenable to probability analysis, lack of the same results in basing CRA on uncertainy. (Meldrum: 2000). Thus analysts tend to construct the risk based on judgmental factors rather than probabilistic criteria. CRA ratings which are easily accessible are by ratings age ncies which measure default risk and equity risk which is generally derived. (Damodaran: 2003). These differing perspectives necessitate the need to evolve systematic methodologies for CRA. Impact of Differing Geographical and Time Perspectives Risks between countries can vary due to national differences in economy, policy, geography, currency and a host of socio-political factors. For example comparing the period in Romania in the pre and post Cold War era uniformly is likely to result in totally varied results. However many times risk analysts tend to use uniform criteria to assess country risks beyond time as well as situations differential faced in making such an assessment. While inclusive country risk measures are correlated with each other, for higher returns risk analysts recommend value-oriented strategies across the board which may create anomalies. (Erb.Harvey.Tadas:1996). Thus factors which are common for all countries need to be identified. Application of financial risk measures is likely to be done uniformly evolving information of future expected returns and political risk criteria are likely to be ignored. (Erb.Harvey.Tadas:1996). This is supported by evidence from ICRG composite, financial and economic ratings, which appear standardised. (Erb.Harvey.Tadas:1996). While economic factors are also evolving the real challenge is to assess the political risk particularly in emerging economies as Romania. Problems of Quantitative and Qualitative Methods CRA include a mix of qualitative and quantitative analysis. Some as the Bank of America World Information Services is based exclusively on quantitative information while the Institutional Investor is a qualitative survey based on opinions of banking professionals taking a number of non quantitative factors

This work is about Geopolitics of Energy subject so please look assignment criteria for topic - Essay Example However, in 2008 the notions of the impeding scarcity had a reverse effect with the producers wanting to make a large profit before the reserveswere depleted. This saw the prices rise continually. At that rate the country would be spending many billions of dollars on importation of petroleum and natural gas. This would create a distress in the economy because of the increased trade deficit. It is true that Asia is the new ground zero for growth of energy consumption.it is also true that Asia will be responsible for 85% of the energy consumption growth on the planet in the next 20 years. This has seen Russia try to form ties with the east to establish a proper market for its hydrocarbon exports3. The obvious deduction from this would be that Russia would wield more geopolitical power in the next few decades, which is not likely to be the case4. The current technological advancements have enabled rapid expansion of the shale gas industry in the US. In a decade, the industry has grown dramatically with the product now in abundant supply,seeing drastic reduction in prices. The policy debate has snow shifted to how much of the nation’s energy resource should be exported. The strengthening of the US’ geopolitical strength due to the shift in paradigms of the global energy market has greatly hindered China’s attempt to be the global leader. The best way to counter this influence would be to weaken the alliances that the US has with states in the region. The result has been the heightening of maritime tensions in the region with the East China Sea conflict providing a good illustration5. Both China and japan lay claim to a number of geographical features found in the sea. The features that comprise of a few islands and territorial waters could provide energy reserves and fishing grounds6. However, this is not the only reason behind the conflict. The key issue is that the waters are important choke

Introduction to UK graduate study Essay Example | Topics and Well Written Essays - 1000 words

Introduction to UK graduate study - Essay Example This reflective essay is a personal reflection about a study module, i.e. introduction module of the UK graduate study and the aspects that I have learned from the module. In the module, I have studied about individual presentation and group presentation, direct and indirect quotation, report writing and essay writing and also about ‘how to write and use the different references’. This module has been of immense benefit and has helped in developing my basic concepts and understandings in various critical aspects that I will require to use not only throughout my graduate degree program but also throughout my life. The introduction to the UK graduate study module has helped me not only to gain practical knowledge and develop my skills related to various key facets such as individual presentation and group presentation method but has also helped to instil within me a sense of cohesion and group bonding. A study module is developed with an aim to provide module-specific skil ls, discipline specific skills and also personal and key skills. The aim of any module is to develop within an individual critical thinking ability, problem solving ability, ability to judge and analyse an available peace of research to correlate and integrate with actual requirement by judging the strengths as well as weaknesses of an available research. I have also been able to learn these key factors through the introduction module. Through the course related to individual presentation, I have been able to learn aspects such as self-management, independent studying capacity, problem solving skills as I had to integrate my learning in the module with the subject matter, i.e. topic provided (University of Exeter, 2011). The group presentation course also helped me to learn basic skills of giving presentation such as searching for relevant data for preparing the slides, preparing slides with relevant contents, distributing overall slides among entire group efficiently, using of verb al and non-verbal language as well as developing body language while speaking. I have also been able to learn and develop persuasive skills and strategies, time management skills, group behaviour skills through presentation course in my module which will be of immeasurable benefits throughout my career (McCarthy & Hatcher, 2002). Another extremely valuable learning that I have acquired through the module is related to report and essay writing. â€Å"Writing is a uni-directional process of recording pre-sorted, pre-digested ideas† (Taylor, 1981). Writing an essay is observed as ‘hi-directional movement’ between two aspects, i.e. content as well as written form. I have also been able to learn various facets on how to integrate my thought process in a written form. This has also helped towards improving my language and vocabulary skills along with my planning and coherent writing skills (Taylor, 1981). Report writing course has also helped me to learn and develop my written communication skills along with the ability to present and use appropriate data and content from various sources such as academic sources. The use of graphs as well as relevant statistics along with writing a report in a proper framework have been all learned by me within the course framework. Both essay and

Idea of translation and related issue Essay Example | Topics and Well Written Essays - 1250 words

Idea of translation and related issue - Essay Example That is why there is such an aspect as a misunderstanding or not understanding of the spoken or heard information. As the practice shows, such a thing as a pure translation is impossible. In any case there are some contributing factors such as the existence of opinions or attitudes to what is translated or interpreted by the person who translates, even some ethical or political reasons with the intention to influence the person who is aimed to hear the message, and so forth. So let’s see how the issue of translation is considered by different scientists – Emmanuel Levinas, Karl Marx in the context of the theme of colonialism and translation and whose ideas and statements are supported by Dr. Suh and whose ones are denounced by him. To begin with it is necessary to admit that both translation theories of Emmanuel Levinas as well as Karl Marx are linked with each other as the first one serves as a basis for the existence of the second one. We will start with Levinas who is well-known by his critics of the tradition of Western philosophical though. According to him â€Å"The sociality of language (or dialogue): cannot be reduced to the exchange of ideas between those who share the same ground of understanding and belong to the commonness† (Suh). So the theory of Levinas’s translation is attached with the main theme of ethical and political practice with the concepts of the â€Å"self† and the â€Å"other†, that is, â€Å"the problem of politics comes up because there are multiple others in the world† (Suh). Another important part in realizing of Levinas’s theory of translation is his concepts of the â€Å"saying† and the â€Å"said† – â€Å"The key t o connecting Levinas’s ethics to actual politics is understanding the relationship between saying and the said† (Suh). In other words, the â€Å"self† and the â€Å"other† have almost nothing common between them that’s

Leader and organizational behavior Research Paper

Leader and organizational behavior - Research Paper Example I maintain that I am the ideal candidate for this job because I am sufficiently educated and possess the adequate qualities that would help me greatly in filling this position. A typical Vice President of Operations of a company as large and progressive as yours would be entitled to be a committed worker. I understand that the duties include creating and upholding the vision and overall direction of the company, and supervising and evaluating the work of other top position-holders, such as department directors, operations managers. Moreover, a Vice President would play a crucial role in the approval and laying out of the day-to-day operations of the company, aiding and assisting subordinates should the need arise while identifying potential areas of improvement. In addition, at times, a Vice President could be required to coordinate with the directors of different departments. Lastly, a Vice President would, of course, be required to analyze a company’s overall performance by reviewing financial statements, customer feedback and sales and activity reports. In general, a good Vice President of Operations would have to be sharp and in control of the operations at hand while maintaining a cohesive work environment to maximize productivity and eliminate internal conflicts. If I were to be awarded this position, I would be fully committed to being hard working and dedicated to the company and, in particular, to my job. In my experience, I have learnt that I work best in demanding conditions by being organized from the get-go and assigning myself goals and aims from the beginning of the project (Smith, 1992). I have found that goal setting helps me greatly because it allows me a sense of focus as opposed to being distracted by unnecessary objectives that should not be given precedence. Simply put, lacking a goal could disperse my attention over all the possible, yet needless, objectives in a certain circumstance. Moreover, because it has been found that the mo re challenging the goal, the greater the motivation to achieve it, I believe my work quality would improve dramatically as I would be more inclined and persistent to work harder. Furthermore, setting goals would help me in using my time more productively by allocating it to the pressing tasks at hand (Wilson, 2008). In addition, I would be using my resources most efficiently (with the least waste) to productively aid the company. I believe setting goals helps in personal growth, all the while motivating you to work harder and more diligently to strive for what you set out to achieve. Setting targets for myself would show me clearly the vision I aim to uphold and would push me harder and harder until I successfully achieve it. For someone in a position as demanding as that of Vice President, some direction is necessary. I feel that setting goals such as being prompt with my work, or being thorough in my reports would better motivate me into becoming a good Vice President for the comp any and would give me a sense of confidence once these goals are realized. In the past, I have worked for various companies and have had to deal with demanding circumstances such as rushed deadlines, miscommunications in the chain-of-command, and conflicting behavior of coworkers and lack of
