Examine The Advantages Of Trading Blocs Economics Essay

Examine The Advantages Of Trading Blocs Economics Essay A trade bloc is a group of countries that have joined together and formulated agreements to promote trade amongst themselves often on preferential terms. They would remove tariffs and other barriers of trade to these partners who in turn reciprocate. One of the best known trade blocs is the EEC (European Economic Community) where the individual countries have no restrictions on trade between themselves, many of the countries have a common currency (the Euro) and labour can freely move from one country in the bloc to another. Before highlighting and explaining the advantages of trading blocs one should know what the meaning of trade blocs is. A trade bloc is a group of different countries who join together for formulating agreements in order to promote trade between them. One of the best called as trade blocs is the EEC which stands for European Economic Community, where individual countries are not restricted for trade between them. Most of the countries have common currency, the Euro, because of which the people or labours can move freely from one country in the bloc to the other. ADVANTAGES Foreign Direct Investment Trade blocs give results to a rise in foreign direct investment. This further is beneficial for the economies of the nations participating. Creation of large markets is been found which results in lower costs for manufacturing goods locally. Economies of Scale Markets which are larger and developed with the help of trade blocs permit or allows economies of scale. If too much production is allowed then the real average cost of production reduces at a greater extent. Competition Positive effect of trade blocs is that lot many manufacturers of different countries come together to work closely. Ofcourse, this result to high rate of competition between them. It is said that increased competition raise to greater efficiency within the firms. Trade Effects -There is no inclusion of tariffs and so takes imports cost downward. Because of this, change of demand is been seen. The customers do purchases on the basis of low prices and allows the firms with a benefit in production to prosper. Market Efficiency An upward direction for consumption experienced with the demand changed further gives a combination of huge amount of goods being produced resulting into an efficient market. Changes in the balance of world trade during the course of the 20th Century The trade balance is the result of the difference between total values of exports and imports of products and services for that particular period of time. Also, trade surplus is the one when a nation ´s total annual exports is more than its total imports that is calculated annually. The main reason for increasing trade is improvement in technologies. Businesses and cusotmers, both have easy access to an product from different countries. Increase in technology also increases the competition among the industries dealing in that. Previously, the world trade was dominated by the trade of Europe and that is really true. Normally, after 1870 with rapid rise in industrialisation, the need for supply of products and services rised then it led its trade with other, world markets to move upward. I further broadened international economy as it brought too many states and countries into trade business this further reinforced the European domination. Thus during 1900 two thirds of Latin America ´s trade went with the Europe and about 90 per cent of Africa and Oceana also were in the same track. Examine how Economies of Scale has benefited specific industries The concept that arises in the form of production of prodruct or service and such other movements taken by all kinds of organisation whether it is non-business or business related is known  ¨Economies of scale ¨ business or nonbusiness organization. Economies of scale has benefited many industries who also participated in foreign trade. Normally, foreign trade is based on specialization, how each or different countries specialized in activities of production of products or services which furhter is a greater advantage. When one finds that there is negligle difference among countries related to the economic effiency for production of products or services, then surely there are benefits for joining in specialization and foreign trade. Other than pure economies of scale in production, there are  ¨economies of scale ¨in learning are related to specialization in foreign context of trade. Here, the average cost per unit falls as efficiencies of economy rises due to learning. In any organization where learning is plays an essential role in causing economies of scale, then there are benefits in one country specializing for that product ´s production. Also, further this can decrease average costs and retail prices to move down compared to those nations who attempt to be self-sufficient in the goods related to economies of scale in learning. Economies of scale also leads to monopoly where in the market there is only one seller for the particular product. Here, when there is only one seller then it can engage in an unfair pricing policy due to lack of competition and the people always insist that monopolist ´s pricing should be regulated by the government. For example, the electric providing industry which is enjoying natural monopoly. Propose reasons why globalisation has led to organisations finding cheaper resources Globalization is a process which embodies an alteration of social relations and transactions in the spatial organisation, generating interregional flows and activity networks, interaction and power. Factors contributing to globalization are huge migration and move of people, communications and transportation technologies and services, the international agreements which decreases business cost in other countries and so on. Globalization have given greater range of profits to countries and companies dealing with it however it is also complicated as it includes various cultures, values, expectation of people, governments and so on. Globalization has both sides of coin, positive and negative. In case of job creation, it has not played so good role as was expected. Due to high competition in informal sector firm ´s survival rate is low, making jobs in these sectors insecure. The other issue highlights is outsourcing which is the result of globalization. Here, the business processes that are outsourced are at lower level related to their skills and efficiency needs. The main concept of outsourcing is that if any firm is not specialized in certain role which it does not feel important then it will outsource the work with cheaper labour. In the beginning outsourcing was limited to only peripheral services however now it has expanded even with the core functions like customer care, financial service, and technological service and so on. Ways in which individuals and businesses can deploy culture to transform social and economic inequalities, and bring about social and economic change Culture gives its meaning as human activity patterns with the symbols that provide significance to these activities. For example,  Ã‚  Indian curry, French cheese and so on  have become more popular in other countries compared to its origin. The companies like McDonalds is the best example for globalisation which is operated in more than 31000 locations across the world. The internet breaks down cultural boundaries across the world by enabling easy, near-instantaneous communication between people anywhere in a variety of digital forms and media. Internet is related to cultural globalisation as it permits communication and interaction between different people staying in different countries, having different styles and cultures. Globalization has generated significant international opposition over concerns that it has increased inequality and environmental degradation.   The effect of globalization on culture is been viewed by some people. With the economies and trade globalization, the culture is also been exported and imported. Sometimes the bigger countries may destroy the cultures of small countries by leading these values and customs towards negligibility. Social   development of the system of  non-governmental organisations  as main agents of global public policy, including humanitarian aid and developmental efforts. Propose ways in which a business can enter into new forms of relationship with diverse cultures to enhance cultural diversity and innovation Culture is complicated and is manifested within the boundaries of the behaviour that is acceptable. Also, culture is not something that comes when we born however it is been  ¨learned ¨. The conscious awareness of cultural standards is very limited. It is a questionable issue for most of the marketers as it is difficult to understand often. One mat disregard the cultural norms of another country even if have no information. When we talk about the new innovation, they do not spread as fast as what we expect. Examples are many for this which includes cellular phones also, as they existed for long duration before actually they were adopted on a wide range. Some characteristics play an important role for less or more spread of the products which are relative advantage, compatibility, complexity, trial ability, and so on. Globalisation is of particular interest to employees of a major organisation Normally, here corporate responsiblity goes with the globalization. So as corporations carry growth through globalization, they have come upon with new challenges which imposes certain hinderances to the growth and the profits. There are several issues which causes lots of oney involved in it. Governement regulations, environmental restrictions and tariffs are includes in the issues. It depends on different organisations how seriously they these issues. Some uses CSR ways in order to get support of people for their global market presence. The competition which is formed globally gives pressure on corporations who deals multinational products in to check the entire supply chain alon with the labor practices from CSR perspective. Reasons why some believe that the current form of globalisation has brought poverty and hardship to millions of workers As per Jagdish Bhagwati, the former adviser to U.N. on globalization, though there are some issues with the fast development, however this globalization also plays a positive role for taking out the people from poverty, to make countries out of poverty. He says that developing countries workers have many choices for their earnings. Educated workers in developing countries now can compete with the global market and put effort to obtain high paid jobs. Production workers in developing countries now have a strong benefit with the whole industrial world. Now, we can talk about disadvantages or other negative consequences that occurs in poorer countries. The main export of these countries is agricultural products which larger countries mostly subsidise their farmers which further reduce the market price for poor farmer ´s crops when compared to what it is in free trade. The recent globalization form with its international rules and regulations has brought poverty and hardship to lot many like millions of workers especially in developing and poorer countries. Their working conditions, wages and job security, all are eaten away. Everyone knows that globalization creates issues for the workers. These issues do not respond to national solutions purely and therefore international response is required from trade union movement for protecting workers and the other social rights too. For example, in India, An important reason, is the trade and investment as to it gives the reason of progress been made in decreasing the poverty and global inequality. The other reasons are good national policies with sound institutions and domestic political stability. After these all progress, the situation of poverty remains the most challenging job for anyone or everyone. Poverty has not diminished however some proportion of people living in poverty throughout the world has decreased. The economic data would represent the difference in 1980s and 1990s. It is not the question that India has to but it is India have to undertake five crucial areas where it have to work in order to achieve the goal. These areas are technological entrepreneurship, new business openings for small as well as medium enterprises, quality management importance, to deal with new prospects in rural regions and lastly financial institution ´s privatisation.

Treatment for Hypothyroidism

Treatment for Hypothyroidism Levothyroxine sodium is a synthetic thyroxine (T4) hormone, and is the mainstay of treatment for hypothyroidism and the suppression of thyroid stimulating hormone (TSH) in patients with thyroid cancer or after thyroidectomy.1 Two main properties of levothyroxine have contributed to a turbulent regulatory history. First, levothyroxine targets a narrow therapeutic range of T4 hormone and requires careful titration to a safe and effective dose.2 Second, levothyroxine is relatively unstable and its degradation is accelerated in response to environmental factors and in the presence of some inert product ingredients.3,4 Between 1991 and 1997 there were at least 10 recalls of different levothyroxine products mostly due to sub-potency or uncertain potency, comprising 150 lots and 100 million tablets.5 Although major regulatory changes were implemented to improve the quality and safety of levothyroxine products in 1997 and again in 2007,5-7 concerns persist about bioequivalence and variation in product potency.8 In a previous study of generic drug use from a nationally representative sample of commercial claims data in late 2013, we found that generic utilization of thyroid agents, mostly comprising levothyroxine, was 61%,9 despite the availability of generic preparations for >10 years. This utilization rate is markedly low given that overall generic uptake is approaching 90% in U.S.10 To encourage use of generic levothyroxine, more information is needed about the healthcare provider and patient barriers to uptake of generic preparations. We used a large electronic health records (EHR) database from a healthcare delivery system to evaluate measurable determinants of, and unexplained variation in, outpatient generic prescribing of levothyroxine. We hypothesized that both patient and provider factors contribute to generic levothyroxine prescribing and that residual variation in providers generic prescribing would persist after accounting for measurable factors. METHODS Race and ethnicity were captured by self-report during routine clinical practice in accordance with U.S. Census standards.13 We identified TSH laboratory results for each patient in the 12 months prior to the index prescription. In the case of multiple measurements, we chose the one closest to (but not after) the date that the index prescription was ordered. We also extracted information on other patient characteristics, including use of concomitant medications, insurance type, and clinical diagnoses. Insurance type was categorized as fee-for-service or preferred provider organization (FFS/PPO), health maintenance organization (HMO; including Medicare Advantage), Medicare, Medicaid, and unknown (including self-pay). For each patient, we calculated a Charlson Comorbidity Index (CCI) score based International Classification of Disease-9 encounter and problem-list diagnoses documented in the 12 months prior to the index prescription.14 We used 2010 U.S. Census block information to deter mine the median householdincome of the Census track in which patients reside as a proxy for socioeconomic status. We used information from the EHR database to characterize the index levothyroxine prescription. We classified the encounter at which the index prescription was ordered as an office or online/telephone encounter. The index prescription was classified as incident if there were no active prescriptions or pharmacy claims for this drug in the 12 months prior; otherwise it was classified as a renewal. For each patient, we quantified the duration of index prescription (recorded start date to the imputed end date, as determined by the prescribed daily dose, quantity dispensed, and number of refills). We quantified healthcare providers prescribing volume of levothyroxine by calculating the average number of levothyroxine prescriptions written per week in the three months prior to the index prescription for each patient. We also quantified healthcare providers total patient volume by calculating the average number of office encounters per week in the three months prior to the index prescription per patient. Statistical Methods We used mixed-effects multivariable logistic regression models to assess the relationship between generic prescribing of levothyroxine (dependent variable) and patient and prescription factors (level-1 predictor variables), and healthcare provider factors (level-2 predictor variables) (see Table 1). We assumed that patients with prescriptions from the same healthcare provider were more alike in their propensity to receive a generic than patients from different providers. Accordingly, we included random-effects (i.e., random intercepts) in our models for each prescribing healthcare provider of the index levothyroxine prescription (N=941). To quantify between-cluster variation, we calculated the intra-class correlation coefficient (ICC) in the absence of covariates (variance-components model) and in the presence of patient, prescription, and provider fixed-effect covariates (mixed-effects multivariable models). These models were also fitted separately by provider type (PCP and endocrin ologist). Odds ratios (OR) and 95% confidence intervals (CIs) were calculated for fixed-effect covariates. We derived predicted probabilities of receiving generic levothyroxine for each fixed-effect covariate from post-hoc estimation of adjusted means, holding all other variables constant.15 We included interaction terms in the mixed-effects multivariable model to examine effect modification by provider type for patient age, sex, race/ethnicity. When interactions were present, we calculated predicted probabilities of receiving generic levothyroxine for the covariate of interest stratified by provider type. Due to multiple comparisons within models, a P-value 220 days vs. 74% for prescriptions à ¢Ã¢â‚¬ °Ã‚ ¤60 days). Patients and providers may have been more accepting of generic levothyroxine when it would be taken for longer periods of time, reflecting lower cumulative out-of-pocket drug cost. The predicted probability of receiving generic levothyroxine was also higher for renewals than incident prescriptions (83 vs. 73%) and for online/telephone encounters versus office encounters (81% vs. 72%). These factors are related, as patients with a renewal more frequently receive levothyroxine during an online/telephone encounter than those with an incident prescription, yet they remained independent predictors of generic prescribing in the multivariable model. Among patients with a renewal, 84% received generic levothyroxine prior to the index prescription and, of those, the vast majority (92%) received a renewal for generic levothyroxine. It follows that patients were less likely to have been prescribed brand levothyroxine if they were already taking a generic. In a study of 36,832 older adults (à ¢Ã¢â‚¬ °Ã‚ ¥65 years) in the U.S. initiating narrow therapeutic index drugs, of which warfarin (48%) and levothyroxine (29%) were the most prevalent, predictors of higher generic drug initiation, included older age, male sex, higher comorbidity, lower Census block median household income, and prior generic utilization. These findings from a Medicare population are overall consistent with our results.23 In our study, bivariate analyses showed that HMO and Medicare beneficiaries were more likely to receive generic levothyroxine; however, this association was mitigated in the presence of other factors in multivariable analyses. We found that provider type was an effect modifier for the relationship between patient sex and generic prescribing of levothyroxine in multivariable models. In stratified analyses, while the predicted probability of receiving generic levothyroxine from a PCP was similar among women and men (81%, each), the probability of receiving a generic from an endocrinologist was disproportionately lower for women (63% vs. 71% for men). Because lower prescribing of generic levothyroxine was observed for endocrinologists but not PCPs, this occurrence is likely driven by provider rather than patient preferences. Future studies are warranted to understand these prescribing practices among endocrinologists. The results of this study should be interpreted in the context of several limitations. The retrospective, observational nature of this study prevents causal inferences. Furthermore, rates of generic prescribing of levothyroxine may overestimate generic utilization of this drug, as some patients may not consent to generic substitution at the pharmacy. Although California has a permissive generic substitution law, patients can still refuse a substitution. In the absence of pharmacy claims, we cannot know whether a generic or branded product was actually dispensed. Nevertheless, in a previous study we showed that our algorithm used to determine brand versus generic prescribing measured by EHR data performs well in predicting actual dispensing patterns.12 Thestudy setting is a healthcare delivery system in Northern California, and we cannot know if our findings are generalizable to other parts of the U.S.; however, the organization is a mixed-payer system, and operates much like other pr ovider-based delivery systems in the nation, without a single drug formulary. As such, we are confident that our findings are relevant to other similar health systems in the U.S. This study has several strengths. We used a relative large cohort of patients from a mixed-payer healthcare delivery system over a four-year period to examine patterns in and determinants of generic prescribing of levothyroxine. We leveraged extensive information from the health systems EHR database, including disease and medication history, TSH levels, and providers levothyroxine prescribing and patient volume. To our knowledge, this is the first study to quantify variation in generic prescribing of levothyroxine between healthcare providers. The presence of residual variation between providers in generic prescribing of levothyroxine, after controlling for important measurable confounders, indicates potential unwarranted variation due to prescribing preferences. Such variation, which may also be influenced by patient beliefs and preferences, can be the target of provider interventions or patient education aimed at improving levothyroxine generic uptake.

Abortion: One Of The Most Controversial Topics Today Essay example --

Abortion: One of the Most Controversial Topics Today In the early American Colonies, English Common Law was adopted by the United States, which declared abortion forbidden. The procedure was ruled a misdemeanor if performed before quickening, which meant â€Å"feeling life,† and a felony if performed after quickening. In the early 1800s, it was discovered that life begins at conception and not when the mother â€Å"feels life.† Eighty-five percent of the states had laws that made all abortions a felony. Between the 1800s and today, many arguments have taken place regarding when life begins for a fetus and to what extent the mother has a right to terminate her pregnancy (Fast Facts: History of the U.S. Abortion Laws, 2003). There have been numerous attempts to change the current laws and/or add to them and the majority of these attempts have failed. The most famous law of them all resulted from the case of Roe v. Wade , is still in effect today and forms the basis for abortion laws and arguments. Important Court Cases   Ã‚  Ã‚  Ã‚  Ã‚  One of the most important dates in abortion history is January 22, 1973. On this date, the Supreme Court struck down all state abortion laws and legalized abortion in all 50 states for the full nine months of pregnancy. A mother’s right to abortion is known as the outcome of Roe v. Wade and falls under a woman’s right to privacy. More specifically, the court ruled that the government could restrict abortion access after the first trimester with laws intended to protect the woman’s health. Also, late-term abortions need the approval of a licensed physician to judge the procedure necessary to protect the mother’s health (Roe v. Wade: The 1973 Supreme Court Decision on State Abortion Laws, 1973) .   Ã‚  Ã‚  Ã‚  Ã‚  According to an article written by Michael W. McConnell, â€Å"the reasoning of Roe v. Wade is an embarrassment to those who take constitutional law seriously, even to many scholars who heartily support the outcome of the case (p. 136).† The first reasoning behind the decision is based on the â€Å"right of privacy† and that it is broad enough to encompass a woman’s decision whether or not to terminate her pregnancy. But the right of privacy is nowhere mentioned in the Constitution, as many would agree. Connell says that judges have found at least the roots of that right in the First Amendment, Ninth Amendment, ... ... No one ever thinks that rape will happen to them, but if it did, your decision now and your decision at that time may be different. Ultimately, should a woman have the right to choose between terminating her pregnancy and a potential life, or continuing with the pregnancy? Bibliography Fast Facts: History of U.S. Abortion Laws.

Free Essays - Achieving Understanding in Amy Tans Joy Luck Club :: Joy Luck Club Essays

Achieving Understanding in Amy Tan's Joy Luck Club In Amy Tan's The Joy Luck Club the daughters are too young and naive to understand their mothers and the hardship they faced. But by the end on the novel the daughters are able to understand where their mothers came from through stories and experiences the mothers tell the daughters their background. This shows that the daughters overall understood the mothers better because through time they were able to experience some of the same conflicts giving them a better understanding. While Jing-Mei Woo is only one of four young women whose stories integrate the novel, her story makes her seem to be the initial character, especially since her tale not only begins and ends the novel, but also strongly develops the theme and plot of the entire book. Her mother, Suyuan Woo was very concerned with people and things they lacked, "Something was always missing...always needed improvements...not in balance" (19). This reveals that Suyuan is lacking something herself and feels not good enough for her family. We later discover her past and the twin girls she left behind in China. This past life draws readers and makes the story more interesting but a little confusing at the same time. This past comes back to Jing-Mei when her mother dies and Jing-Mei begins to understand how hard it is to let go of the people you love, which makes her become more open, understanding and mature. She lost a mother she got to share her life with, but like her half sisters, they did n't understand their mother until she was gone to share the experience of being reunited. In a sense, her spirit was there to capture their happiness of finally meeting one another. Although Waverly Jong is perceived in being an intelligent, ambitious, proud, and arrogant, she is constantly struggling with everything that happens in her life. Her unwillingness to adapt to change becomes a major conflict. "Bite back your tongue"(89) her mother's harshness on her while growing up may have caused her lack of self-confidence foiled but assurance. Not only that caused her to resent her mother but the way she introduced her to perfect strangers, "This is my daughter Waver-ly Jong"(101) just to tell people or make reference to the TIME article on Waverly cause her to become upset.

A Study of Cotton Trade and Trade in Africa Essay -- Essays Papers

A Study of Cotton Trade and Trade in Africa History of Cotton The word cotton is derived from the Arabic word ‘qutun’ or ‘kutun’ which is used to describe any textile that is very fine. Cotton is one of the oldest known fibers in the world, which has been found by archeologists during the course of excavating ancient civilizations. Traces of cotton fiber were found to exist over 5000 years ago, when archeologists were excavating a cite in Mohenjo Daro, which lies in the Indus Valley in West Pakistan. Alexander the great and his army brought cotton goods and material to Europe around 300BC. However, the price of these cotton goods was so expensive that only the rich could afford it. The southern states of America started growing cotton in the early 17th century and also making cotton goods and materials out of it. The acquisition of colonies around the world by Great Britain, led to tremendous development of the cotton industry because most of Britain’s colonies were suitable for cotton growth. In the early 19th century the southern American states became the biggest single supplier of cotton to the now thriving English textile mills. In the early 1900s, United States was the producing more then 50% of the total world cotton. Growing conditions for cotton Cotton plants have a growth cycle of about 6 months from the time they germinate to the time they are picked. Cotton seeds are usually planted in spring or as soon as the soil temperature is warm enough to ensure satisfactory seed germination and crop establishment cotton plants grow well in areas that hot summers/dry spells with low humidity and long hours of sunshine. The plant usually requires about 150 days free from frost.

Child Rearing Styles

My research participants were working class parents, one of whom is a 35 year old Indian male which is the same ethnic group as I am (participant 1) and the other a 26 year old White male (participant 2). With regard to the information gathered, both parents have similar parenting styles. Both scored highest for authoritative child-rearing style (32 for participant 1 and 38 for participant 2) and second highest on authoritarian parenting style (with scores of 31 and 35 respectively). Tutorial Letter 101 for PYC4805 (2013) mentions that high scores of these two parenting styles could indicate that these parents follow the authoritative style but may act in accordance with the authoritarian style in certain situations (Tut letter 101 PYC4805). Kendra Cherry of About. com enlightens us on each parenting style; the authoritative style parents establish rules and guidelines for which children are expected to follow. This parenting style is much more democratic. Parents are responsive, nurturing, forgiving rather than punishing as well as willing to listen to their children and supply them with advice and guidance. The authoritarian style explains that there are strict rules which parents implement for their children to follow and failure of abiding by these rules is most likely to result in punishment. Parents of this style generally neglect to explain the reasoning behind these rules. These parents place high demands on their children, but are not responsive to them. Uninvolved parenting styles yielded the lowest scores of 19 and 10 for each participant; this is characterised by few demands, low responsiveness and little communication. The prosocial behaviour scores were again very similar (participant 1 scored 90 and participant 2 scored 87). Participant one's child is a 5 year old boy and has more experience in social settings with other children. He attends school and has 3 siblings of which he is the second child, as well as spending a lot of time with other family members, especially his grandparents; this creates many environments in which to adapt and learn prosocial skills. Dekovic & Janssens (1992) found that a child's acceptance by a peer group plays an important role in his or her social and personality development. Participant two's child is a 2 year old boy, is an only child and does not attend day-care and lacks exposure to social settings involving other children. He spends on average, 70 hours a week with his father and is also at an age where he depends on the care of his parents more. Participant 1 spends an average of 29 hours a week.
