Impact of trade on Inequality Essay Example | Topics and Well Written Essays - 250 words

Impact of trade on Inequality - Essay Example Mostly, this takes place because the usage and the application of various useful technologies in trade is only available to the highly skilled and trained people but not to the unskilled and the poor. During several previous centuries, inequality in world trade has been on the rise. Income within most countries has been rising and declining drastically. Specifically, it has been increasing in the developing countries and falling in the highly industrialized and developed nations. However, this trend is becoming reversed in the Organization for Economic Cooperation and Development. This implies that there is no global inequality trend for the previous two centuries. Therefore, almost all the rise in world income inequality has taken place due to the increasing gaps between countries rather than increase of gaps within countries. Meanwhile, integration in world economy has advanced. If this relationship meant causation, it would be that the increase in inequality among nations has been caused by globalization but inequality within nations has not been elevated. The effects of globalization and its result have gone both ways with respect to disparity within nations. This is accordin g to simple correlation between the perceived trends. The following conclusions can be deducted from the economic record of inequality: a) The disparity between incomes among countries has reduced. This has been the result of the globalization factor as well as commodity markets for the nations that have been integrated into the global economy. b) Inequality has also been lowered by opening up to the international business as well as the international factor movements within labor-filled countries. This has taken place within the past few decades. e) Global incomes would continue to be persistent especially under a complete global integration. This is similar to inequality in large integrated economies from a domestic perspective. This situation is lower in a completely integrated

Marketing strategies Essay Example | Topics and Well Written Essays - 3000 words

Marketing strategies - Essay Example For marketing strategies to be effectively implemented there must be marketing objectives. These objectives shape the perception and approach to the market. The objectives are generated in regards to the requirements and goals set by the management team. Kotler & Armstrong points out that marketing objectives are set as goals that an organization tends to achieve in terms of acquiring a greater competitive advantage over other organizations (65). Marketing objectives are also used as measurement tools of the effectiveness of the strategies applied in the market. If a marketing strategy satisfies all the requirements stipulated in the objectives, it is allowed a greater lifeline in an organization. Additionally, marketing objectives dictate the mode in which promotional activities will be integrated. Promotional activities are activities that are used in the marketing of an organization’s goods and services. In referring to the definition by Kotler & Armstrong promotional activ ities are forms and ways of marketing implemented by organizations (112). Promotional activities include personal selling, exhibitions, media marketing, corporate image, public relations and sales promotion. Depending on the organizational culture and marketing objectives, an organization selects the forms of promotional activities to be implemented in the organizational system. ... In such an organization, the first objective would be to create a corporate image for the facility. This can be done by providing special services and offers upon interest on the facility. The organization may also a marketing objective of reaching out to corporate bodies. To realize this objective the most proper promotional activity to be implemented would be personal selling. By personal selling the relationship between the interested parties and the organization is more personalized (Kotler & Armstrong 89). In a sporting facility a good public relation with the communities is a compulsory objective. In this case, the organization may opt to implement Corporate Social responsibility as a promotional activity and tool. This entails organizing communal activities and funding community projects (Kotler & Armstrong 64). From the analysis one could easily argue that the objectives set by an organization in terms of acquiring a greater market support significantly dictates the type of t he promotional activities used by an organization. The integration of promotional activities is done by an analysis of the opportunities that the market presents to an organization. For instance, if an organization aims to capture the attention of a specific market population for example the young people: the advertising promotional activity would be integrated in a way that social sites and trendy magazines are effectively exhausted (Kotler & Armstrong 77). What is the importance of the three extra elements of the service mix to you as the customer? According to Kotler & Armstrong it is human nature for a consumer to be selective in the way they chose to relate to an organization (154). This relationship is a great determinant of the consumer’s allegiance to an

Qs need to be answers - Assignment Example The parents, with their experience and knowledge, will mostly make sound and good judgments about their children’s diet. However, I also believe that Ellen Satter should have urged Michelle Obama to help the impoverished families in obtaining the wherewithal and knowledge regarding healthy and balanced diets, and not just talk about the privileged or middle class families who have the capacity to include fruits and vegetables and other healthy, yet comparatively more expensive, food choices in their children’s diet. Q2. (a) I believe the concerns that have prompted organizations like â€Å"Concerned Children’s Advertisers† are very legitimate and real. We live in a society where most of the children are constantly bombarded by advertisements in various media; whether it is television programming, magazines for children or websites, children are always surrounded by various advertisements. It is our role, as a society, to make sure that our children have the knowledge and information to deal with these advertisements. If the children are not media literate, then a lot of the advertisements they see are taken by them at face value, and, consequently, as their minds are young and naà ¯ve, be influenced greatly by them. It is not enough to lay the blame on the advertisers, and it is naà ¯ve to expect them to change their policies regarding their advertisements that are aimed at children specifically. In consequence, it is actually very wise and prudent to take up the cause of educat ing the children, so that they themselves can discern the various nuances of the advertisement and make informed choices based on them. (b) After reading Advertising and Obesity: A Behavioral Perspective, I cannot help but agree with the assertion that it is not advertising alone that is to be blamed for obesity. Not only can advertising have minimal to no

Individual politics assignment - Essay Example Department also considers the financial needs of every policy (A.H.C. S.A, 2004). In her budget of 2014, the Australian government made certain policies directed towards bringing new changes to the health sector. The Minister of Health mentioned three policies in the Dutton conference. The paper analyses these policies to identify their strengths and weaknesses. The paper also identifies the perspectives of the claims presented. It will also make some comparison between the stated plans with those of foreign countries. Australia has a high percentage of ageing people (Australian Bureau of Statistics, 2013). Unlike in the 1970 and 1971, a youthful generation has dropped to 22% from 31% in the early 1970s (M.H.C.C. A.C.T., & C.S S., 2007). The government through its various departments projects that in the coming 40 years, 25% of the Australian population will be people with over 65 years of age (Australia, 2011). In the health sector, the country is facing the problems associated with old age. The government understands this and is planning to offer more support for the sector so that it can improve its services to serve more people. Currently, the public health system is only able to serve, on a weekly basis, 170 people diagnosed with dementia. However, the country has to prepare for the future. The government projects that in 2050; there would be 7,500 cases of dementia per week (W.A.C.O.S.H, 2007). The country thus has to get ready to face such an issue in the future. Therefore, in the 2014 budg et, the government allocated more money for the expansion of services like genomics testing in MRI and MBS screening. The argument of the government is valid considering the real situation in Australia. There is a sociological problem. Australian population is aging at high rate. The health sector has to prepare to face this

Servant leadership Essay Example | Topics and Well Written Essays - 2000 words

Servant leadership - Essay Example The authoritarian leadership style denotes a centralized decision making approach where the final decision is taken by the topmost executive. The participative leadership style indicates that employees should be included within the decision making process. Employees are able to influence the decision making approach, and simultaneously the responsibility of team members also increases. The laissez-faire leadership approach is the least observed within an organizational system. There are similarities between servant leadership and participative leadership styles. In the current scenario there is a wide range of firms following the servant leadership approach. The servant leadership style is valued by many organizations so as to strengthen employee relationships. The organization selected for this particular study is Prince’s Court. This is a healthcare provider that aims at providing family-centered and quality healthcare to individuals. The study will summarize the implementat ion of the service leadership approach within the chosen organizational framework. The servant leadership concept suggests the primary role of a leader is to extend support towards team members or to serve them appropriately. This approach does not believe in exercising power over other team members, but distributes power amongst all individuals. It is an ancient philosophy and is closely knitted with the concept of participative leadership approach. A servant leader possesses certain priorities such as enabling, encouraging and supporting subordinates to address specific goals or objectives. This eventually leads to distribution of power and responsibility amongst employees. It can be considered as a participative decision making style, where all team members contribute their opinions or ideas (Mello, 2011). Servant leadership approach is not only confined to employee related behavior but its objective is to alter hierarchical relationship between team members

Business - Essay Example They both provide the English legal system necessary tools for the correct and fair application of law. They are flexible yet rigid so as to ensure consistency of approach and certainty of law.1 Statutory Interpretation Parliament has the power to enact laws. The law making is subject to a long and complicated process. Courts in England and Wales have the power to interpret these laws (statutes) made by the Parliament whenever cases involving the respective statutes appear before them during the course of judicial proceedings. The judges/courts will explain how the relevant law is applicable in practice to the problems the courts are seized of during the course of litigation process. The meanings of the words appearing in the statutes of Parliament are interpretable by the judges in accordance with Statutory rules and Common law rules. Statutory method consists of Interpretation Act 1978 and Internal or Intrinsic aids while Common law method consists of literal rule by which courts r ender plain meaning to the words irrespective of result, golden rule by which courts adopt the meaning of the words more appealing to common sense in the case of more than one meaning being attributed to the word in question, mischief rule by which the judge has to interpret in the light of knowledge if the law has a defect or mischief , ejusdem generic rule which requires words must be interpreted as a person or thing belonging to the same class or genus, expressio unius est exclusion alterius rule which means that in case of a rule mentioning one or more things, other should be excluded oscitus a soccis rule which requires to follow the contextual meaning of a word in question. Further there are presumptions and use of extrinsic material. The presumptions entail that courts can a make various assumptions such as act not with retrospective effect, not binding the crown, not altering the common law, restricting personal liberty and creating criminal liability. The extrinsic material s serve as sources of information. They are International Conventions and Treaties, Law Commission Reports and Hansard proceedings which once had not been allowed to be used for statutory interpretation2. Judicial precedent Judicial precedent is common law system by which a precedent serves as an authority, principle or rule established in a litigation formerly decided. This becomes a binding or persuasive precedent for lower courts or tribunal to be followed in deciding future cases with similar facts or issues. The precedent appears in various forms. They are precedent in action that refers to the judge’s speech in a judgement, European Court of Justice (ECJ) since all the English courts are bound by the ECJ concerning European law with effect from 1973, The Supreme Court (formerly House of Lords) as this is the highest domestic court of appeal serving as the judicial authority which the House of Lords enjoyed formerly. Court of appeal whose decisions are binding on the Hig h Court and whose decisions are bound to the Supreme Court, Divisional Courts who are bound by the decisions of Supreme Court and Court of Appeal and High Court which is bound by the decisions of Supreme Court, the Court of Appeal and Divisional Court and not by another High court judge. 3 It would be clear therefore judiciary’s function is not to simply apply the laws but to interpret them and establish binding precedents. It is because there are difficulties in drafting out legislation and there are chances of unintended meanings and ambiguities creeping in the statutes. In many cases, the Parliament’s intent will be very clear in which case it will facilitate Court’s interpretation in an unambiguous manner. Courts are enabled to
