Argumentative Essay-Underage Drinking

Jane Doe Ms. Smith English 11 17 October 2011 Underage Drinking and You According to Answers. com, an average of twelve thousand nine hundred eighty two people die a year from underage drinking; many of them being car accidents. With so many people underage drinking, I feel that the law should be heavily enforced that underage drinking is NOT okay. There should be no underage drinking, whatsoever, under the legal age of twenty one. Underage drinking is very hard on the human’s brain development. The front part of your brain, the decision maker, is not fully developed until you are an adult. Drinking before that age can impact your brains healthy development. Many people may not know how to handle drinking, and the amount that their body is consuming. Some people may argue that alcohol makes them â€Å"feel good. † These people obviously have no concept of life, because if you do other things you enjoy such as; sports, clubs, movies, hang out with friends, etc. You could find many other activities that can make you feel good. Underage drinking cause’s people to make bad decisions, such as; driving while intoxicated, becoming pregnant, and making a complete fool of themselves while intoxicated, are just be a few instances that can and will impact your life forever. Some individuals don’t understand what alcohol really does to the body. Beer has empty calories that will make you gain weight. Which is why a lot of alcoholics have larger stomachs, or another term many people use for these large stomachs is, â€Å"beer belly. Some people may say that alcohol helps you escape your problems and is a stress relevant. Alcohol will not only bring more stress onto your life, it will also bring more problems. As much as people may feel alcohol helps, it really won’t help. If you need help that bad, I would suggest a therapist to help you with your problems, not a depressant. So that doesn’t make a whole lot of sense. The last statement to be made about underage drinking is the fact that i t will start to make you feel completely careless. Your grades in school, and in life for that matter, will drop. School is a huge part of our everyday life. It is the main component to a happy future, because without your education you will not be successful in life. Most teens will argue that their brains are already developed and that â€Å"everyone is doing it†. In reality, your brain is actually not fully developed as told above. And everyone is not doing it, if everyone did it, everyone would be bums. The individuals, who are strong believers in not drinking alcohol while under the age, are very successful in life. But not all people will follow in their footsteps. There are many reasons to back up the fact that underage drinking should be heavily enforced. Remember how hard alcohol is on the brain, your bodily development, and the struggles it will make you go through in life. Alcohol is not the answer to any of our problems. Take a stand in your life and make the right decisions. What will you decide is the right choice for you?

Feminist Interpretation of Hemingway’s Story

Portfolio Popovics Anamaria, An II, Romà ¢n?-Englez? L121A feminist interpretation of Hemingway's †Hills like White Elephants† Hemingway's works have largely covered the subject of feminism, and his short story †Hills like white elephants† perfectly portrays a woman who breaks the norms of a society dominated by men and masculinity. As we all know, feminism is a social movement , an ideology which focuses on achieving rights for women . Women should be equal to men in each and every way. In Hemingway's short story we have two important characters: The American and The Girl. It should be noted that we can acknowledge only from the nicknames the author gives us that †The American† seems to be superior from a plain old †Girl† . Is the girl American too ? Is she of another nationality? We aren't told this , but this makes us wonder just how important women were in the 20th century , how much they depended on men , how they didn't matter in society , how their feelings or opinions were pretty much non existent. This simple question gives a major clue on who is superior and who is inferior in the couple's relationship. Even from the beginning , when the Girl asks her partner about what they should drink , we can pretty much realise just how much she cares for her boyfriend's opinions and thoughts. It may seem just as a simple question , but if we analyze the whole text we surely get to the conclusion that the Girl really has surpressed feelings, frustrations , her own thoughts only get voice at the end of the short story , when she finally sees just how her relationship really is. The girl is clearly submissive to her dominant boyfriend, and she wants to do the things that please him. She is inferior in this case as she doesn't know the Spanish language, she can't order by herself, she depends on her boyfriend. I think that there are many famales who depend on their partner, but that it is much better to be an independent woman. Women shouldn't feel inferior to men, they should consider themselves as men's equals. The woman is clearly used to pleasing her boyfriend and doing whatever he wants.†Although â€Å"Hills Like White Elephants† is primarily a conversation between the American man and his girlfriend, neither of the speakers truly communicates with the other, highlighting the rift between the two. Both talk, but neither listens or understands the other's point of view. Frustrated and placating, the American man will say almost anything to convince his girlfriend to have the operation, which, although never mentioned by name, is understood to be an abortion.†Ã‚  (Source : SparkNotes Editors. â€Å"SparkNote on Hills Like White Elephants.† SparkNotes.com. SparkNotes LLC. 2007. Web. 19 May 2017.) The American man's girlfriend is a girl who doesn't speak up when talking about the abortion. It is clear that she doesn't want to have it, and even though she doesn't argue with her boyfriend their conversation is really tensionate. She is the typical american girl in the 20th century, a girl that would to anything for the man she loves, not caring about the consequences. I would now like to talk about Jig's (the nickname the Girl is given by her boyfriend, we don't know her actual name) feminist journey thourought the really short story. At the beginning , she really seems to be willing to do anything she can to save her relationship , even have an operation , an abortion . I truly believe she wakes up at one point in the conversation and realises there is nothing to save , that an abortion can't fix what's already damaged in the relationship . The American is clearly oblivious to his girlfriend's or, better said, the mother of his unborn child's needs and true wishes, and he really pressures her to do something that mainly affects her, she should be the one taking the decision about having a child or not , not anyone else. One quote of the text regarding the feiminist awakening in the Girl's soul is particularly important and worth mentioning : † Then I'll do it, I don't care about me.†(Source : †Hills like white elephants, by Ernest Hemingway from Charters, Ann, Ed. The Story and its Writer: An Introduction to Short Fiction. 6th Ed. Boston: Bedford/St. Martin's, 2003). This quote is especially relevant from a feminist point of view. Even though, at first, I actually thought that the woman wants to please her boyfriend and do as he wants her to do, I think that this is the moment she actually realises that everything she's done so far was only for him, she was careless when it came to her needs, her wishes and she is now actually waking up. She seems to realise just how much her dominant boyfriend is asking of her and she seems to have had enough. If we think about reporting this quote to real life we may say that women, even today, care about their partner's feeling more than they care about their own person. In today's relationships men try to dominate women and try to have the upper hand, and women are unfortunately are usually inferior to their partner and get to a point where they feel helpless, with low self-esteem and unhappy. Another quote that gives a glimpse of the Girl's realization that she does in fact want to keep the baby and doesn't want to have any operation at all is â€Å"But if I do it, then it will be nice again if I say things are like white elephants, and you'll like it?† (Source : †Hills like white elephants, by Ernest Hemingway from Charters, Ann, Ed. The Story and its Writer: An Introduction to Short Fiction. 6th Ed. Boston: Bedford/St. Martin's, 2003) †By this point, midway through the story, the girl has already retracted her previous comment that the surrounding hills look like white elephants, hinting that she wants to keep the baby instead of having an abortion. The man had been upset at this, feigning indifference but pushing for the abortion because he doesn't want the child. Still hoping to save their broken relationship, the girl asks her boyfriend whether things between them will return to the way they used to be if she goes through with the abortion. Her indecision and desire to placate the man demonstrate her dependence on him. At the same time, however, the mere fact that she asks the question may imply that she believes that nothing can save their relationship.† (Source : SparkNotes Editors. â€Å"SparkNote on Hills Like White Elephants.† SparkNotes.com. SparkNotes LLC. 2007. Web. 19 May 2017) This quote unveils, once again, Jig's awakening. She subtly hints at the fact that she doesn't want to have the operation, but wants the relationship between her and the American to be a happy and successfull one, as it once was. She asks this question knowing that things may never be as they once were, she slowly realizes that the relationship has reached its finish, and that no operation can fix what made the couple grow apart. I feel like the Girl's feelings are finally surfacing, and that the American is at this point as clueless as he can be. The not so long conversation between the two is a real game changer for the relationship. The two aren't arguing or shouting, but the dialogue is really tensionate, it truly shows that there are a lot of things on the deeper level. The Girl is no longer just a plain girl, she has a voice, she has feelings and she is not afraid to speak up anymore, even though the one she is talking to doesn't understand much at all. In the end, I am completely sure that she is coming out of her submissive girfriend shell and that she realizes she can be an independent woman, taking care of a child without the help of its father. Hemingway doesn't actually tells us if the woman decides to have the abortion or not, but from all the subltle hints in the Girl's dialogue I think it is safe to assume that she is keeping the baby and getting out of the toxic relationship with her overly dominant boyfriend. To conclude my essay, I would like to state the fact that this short story is truly a story of a woman who has her feminist awakening, a woman who gets out of the cage she's been kept in by her dominant partner, a woman who finally speaks up her mind. Hemingway ingeniously brings to life an independent, strong woman, and a real life situation common to our days.

Sales promotions Essay Example | Topics and Well Written Essays - 250 words

Sales promotions - Essay Example Managers’ tendency to rely on sales promotion has increased over the passage of time because sales promotion triggers the buyer action serving as a short-term tool while advertising shapes the attitude of market toward the brand in the long-run (Kotler, 2003). A very effective way of sales promotion is the use of coupons. In this strategy, customers either cut the coupons from newspapers or receive them on their own so as to be able to buy products at discounts (Rikey, 2012). Rebates are of two kinds; â€Å"an instate rebate, where the discount is taken immediately at the store register, or a mail-in rebate, or MIR, where the customer must fill out documentation, and mail it in order to receive their refund† (Miller, 2014).

Repeat purchase is rewarded by continuity programs and

Common law and equity Essay Example | Topics and Well Written Essays - 1000 words

Common law and equity - Essay Example Equity was developed in order to overcome the inadequacies of common law. Equitable remedies are available in a number of areas where common law is either incapable of providing justice or is not faultless in providing justice to the individuals. The main purpose of equity jurisdiction is to support the existing laws. Equity was developed to propose principles that are either ignored by common law or not formally accepted in that set of law. Moreover, equity proposes certain remedies that are unavailable in common law. In certain circumstance, common law decisions or remedies are insufficient to provide justice to the innocent (Hudson, 2009). For instance, in the matters involving mortgages, where the lenders are to a piece of land as a security of the loan granted, the principles in equity and common law greatly distinguish from each other. Let’s assume that Angelina grants a loan of $5,000 to Joseph, after considering a piece of land as a security that worth $8,000. Accordin g to the contract, the land in question would be legally transferred on the name of the lender (Angelina), on the terms that she would retransfer the land on Josephs name if he repays the loan in the specified time. If Joseph fails to repay the loan in the specified time, common law gives no entitlement to Joseph for the land that was conveyed and the duty to repay the loan still exists. However, equity practices such situations in a different and more reasonable manner. According to the rules of equity, Joseph would be given another chance to repay the loan in a new specified time. If Joseph still fails to repay, the land which was let for security will be sold and the loan will be repaid. The additional amount would be given to Joseph as it belongs to him. It is not just the matters of mortgages where equity provides a more reasonable and just decision but it also works better in many other areas. Equity and common law are not only different in terms of laws and

Hinduism Chapter 15 of Bhagavad Gita with reference to Upanishads Essay

Hinduism Chapter 15 of Bhagavad Gita with reference to Upanishads - Essay Example Schweig. Graham M. Schweig’s â€Å"Bhagavad Gita: The Beloved Lord's Secret Love Song† encompasses the metaphysical concepts such as the distinction between body and soul (matter/spirit), the principle of nonattached action, the virtues of disciplines†¦ and the respective places of knowledge and devotion in spiritual life† (Rosen 108). In addition, Lord Krishna shares wisdom about the true nature of God, World and Beings and the underlying oneness of God and Being. In â€Å"The Ultimate Person† chapter of the Bhagavad Gita, the conversation between the Lord Krishna, the teacher and the student Arjuna was presented. Lord Krishna imparts his knowledge through his teachings comprising the whole Veda. The central point of his philosophy is on how to accomplish and acknowledge the Supreme Being. Through his teachings, the essence of various disciplines such as Meditation, Karma Yoga, Values, Devotion, are relayed to his followers. In this chapter, Lord Kris hna exposed the transcendental characteristics of God, his glories and virtues, and his being omniscient, omnipotent and omnipresent. The realization of the Ultimate Truth was revealed as the purpose and value of recognizing God was established through the teachings (Radhakrishnan 48). The composition of the universe and its association with man was discussed as personified by the sacred Ashwattha tree. The relationship of the eternal immortality of the soul of humans with the idea of the Supreme Being was described through the limitless character of the tree, also called as banyan or fig tree. Lord Krishna metaphorically described that the everlasting tree was upside-down, where the roots are located above and the branches below. The leaves of the tree represent the Vedic scriptures, and whoever understands this is well-informed of such (Bhagavad-Gita Trust), With its roots upward, and its branches downward they speak of the everlasting Ashwattha tree, Whose leaves are the Vedic hy mns one who knows this is the knower of the Vedas (Schweig 193). A sacred banyan tree is limitless, dispersed everywhere in space. The root of the tree represents the sacred being, its leaves as its written wisdom, and its shoots as the substance of the mind. According to a commentary of Sridhara Swami quoted by Bhagavad-Gita Trust, †¦the compassionate Supreme Lord first expounds the nature of this mundane material existence by the metaphor of asvattha or banyan tree with its roots upwards and its branches downwards and its leaves the Vedic aphorisms. The roots above refers to the root of all the eternal Supreme Lord and the imperishable atma or immortal soul. The branches downward refers to transitory living entities consisting of the demigods headed by Brahma, who all have a finite span of life in material existence even if they live for millions and billions of years. The banyan tree also symbolizes the temporary nature of the material world. Even the followers of the Lord K rishna may not last until tomorrow, for everything in this world is transitory. The Vedas, as exemplified by the leaves,

Consumer Research on Ethical Consumption Essay Example | Topics and Well Written Essays - 3250 words

Consumer Research on Ethical Consumption - Essay Example General assumption on relationship between attitudes and behavior is the consistency. This is known as principle of consistency which means expectation on consistency of one’s behavior with the attitudes hold by them. Furthermore it means people are rational and try to behave rationally at every time. Though this principle is through, it is clear that consumers do not always follow that. Sometimes it is able to experience irrational behavior. For an instance, majority of consumers are smoking cigarettes while knowing this consumption causes heart diseases and lung cancers. Literature relevant to theory of reasoned action and theory of planned behavior are significant theories that discussed this attitude-behavior relationship in-depth manner. Attitude is defined as a permanent, general evaluation regarding people or person, objects, issues or advertisements (Soloman et.al, 2010). Difficulty of changing and nature of evaluating something are discussed as the characteristics of attitude according to above definition. Relationship between attitude and behavior is presented by Fishbein and Ajzen (1975) based on theory of reasoned action. As theorized by Gordon W. Allport in 1935, there is a multidimensional relationship in between attitude and behavior but not one-dimensional relationship. It means attitude is a complex system that consists with individual’s belief regarding the object, feeling on the object and action tendencies towards the object.

Rhetorics and Stereotypes Essay Example | Topics and Well Written Essays - 750 words - 1

Rhetorics and Stereotypes - Essay Example Rhetoric and stereotyping go well with each other especially that people are using rhetoric to influence and keep stereotyping in practice. Stereotyping is also â€Å"implanted† in the mind from the early age and it is difficult to battle with, especially that the rhetoric acts on the mind as a persuasive tool.   Stereotyping is the concept which binds people with similar traits or attributes in a particular class. Stereotyping has its positive and negative impacts. Most of the people associate it with the discriminatory act against groups. Stereotyping promotes the group evaluation and value rather than individuals. People belonging to one stereotype are presumed to have traits which are attributed to that particular class regardless of the individual identities of people and their traits. Stereotyping, hence, creates difficulties for people who belong to a particular stereotype group but have different traits like politicians who are mostly known as corrupt people regardless of the individual nature and qualities of politicians. Stereotyping and its effects are different on every group. This paper, however, aims to analyze the Politicians, Tattooed persons, feminists and senior citizens as the major discussion in the field of rhetoric and stereotyping. The tattooed individuals are bound together in a single stereotyping group as per their similar practice of tattoos on their body. The similar trait of signing tattoos may differ in design, maxims, slogans, message and size. This stereotyped group is often associated with rockers, punks, criminals etc. In other words we may say that these people are not regarded as reverend as soldiers, older people, teachers etc. the group called feminists represents those who are highly in favor of equality and/or superiority of women over men. The people associated with this group are more concerned about freedom and rights of women in the society. People often consider them to have the feelings of

Femininity in American Cinema Essay Example | Topics and Well Written Essays - 500 words

Femininity in American Cinema - Essay Example Most Hollywood pictures were based on scripts which had a plainly obvious adherence to the tried and tested formula of the attraction between the sexes, where the feminine element played centre stage. The female was largely seen to be responsible for the occurrence of the various events in the plot, which were unfailingly the result of the male-female chemistry prevalent in the perception of society. A classic example of the feminine element in American cinema would be the 1998 romantic comedy â€Å"You’ve Got Mail†. Meg Ryan portrays Kathleen Kelly who is involved with Frank Navasky (Greg Kinnear), while maintaining the fact that the two were otherwise acquainted in business. While Frank, as a newspaper writer for the New York Observer, is devoted to the typewriter, Kathleen prefers her laptop and logging into her AOL e-mail account [1]. This maybe interpreted as a portrayal of the sense of adaptation of the modern female as opposed to the modern male who maybe seen as sticking to the traditional path of existence. A further shade of thought may lie in the storyline where the hero runs a considerably large bookstore with commercial values taking the forefront, while the heroine runs a small corner shop book store. This may be a subtle allusion to the subordination supposedly meted out from one gender to the other, in the backdrop of a long online courtship without either party being aware of the other’s identity. Yet another 1998 film, â€Å"Savior†, portrays a different shade of the feminine element. The film portrays a Serbian woman and her newborn child being escorted by an American soldier to a safe house during the Bosnian War. This may well be an allusion to the primitive idea of the protection warranted by the fairer sex. The portrayal of the feminine element here, as with most of the citable examples, is largely an instrument to emphasize the different shades of the masculine form.

Accounting Standards Boards Essay Example for Free

Accounting Standards Boards Essay Increased globalization in the business world has brought to fore some of the issues and challenges that multinational businesses face in financial recording and reporting of foreign based operations. With operations based in different countries that operate under different accounting principles and with varying currencies, there has been a need for the accounting principles and standards to be converged. This has in the past nine years seen the accounting policy making suggesting a complete overhaul in the way financial statements are reported and a convergence between the USs generally accepted accounting principles (US GAAP) and the International Financial Reporting Standards (IFRS). This has been through various meetings between the International Accounting Standards Board (IASB) and US Financial Accounting Standards Board (FASB), two boards which determine these accounting standards. This paper therefore evaluates the history of the two boards and their relationship and looks at IASB equivalents to FASB original pronouncements. It also describes how a Master of Science in Accounting would prepare a student for an accounting profession. History of the Relationship between FASB and IASB US Financial Accounting Standards Board (FASB) is a board which is responsible for setting and improving financial accounting standards in the US and for governing and fostering preparation of financial reports by non-governmental organizations (Financial Accounting Standards Board, 2012).International Accounting Standards Board (IASB) on the other hand is also an independent board responsible for setting international financial reporting standards (IFRS Foundation, 2011). Whereas IASB and IFRS takes a principle based approach to accounting standards setting, FASBS GAAP does this through pronouncements which are based or rules. They both put a lot of emphasis on income statements, balance sheet, statements of changes in equity and cash flow statements as key reports that are important in financial reporting. Over the past decade these two boards which determine the accounting standards in the world have been working towards ensuring that the financial reporting all over the world converges. The convergence concept first took root in the 1950s in response to the cross border capital inflows that were as a result of the economic integration after world war two. These efforts initially focused on reducing difference in accounting principles between major capital markets globally otherwise referred to as harmonization of the accounting principles. By 1990s the concept had changed into convergence which sought to build high quality financial reporting standards to be applied internationally (Financial Accounting Standards Board, 2012a). Both developed in the 1970s, FASB and IASC (international Accounting Standards Committee) a predecessor to IASB, set a trend for expanding international accounting standards and with the reorganization of IASC into IASB in 2001, the use of IFRS among various countries has progressed rapidly. For instance, over 100 countries and the European Union use these standards issued by IASB. The U.S. mainly uses its own issued US GAAP (Progress Report, 2011; Cain, 2008). IASB and FASB have been working together towards converging the IFRS and the US GAAP since 2002. Even China and Japan have been working to bring together their accounting standards with IFRS as at 2009. Over the past decade the pace of convergence has been very fast with the internationalization of standards growing rapidly. In 2010, Securities and Exchange Commission in the US issues a report supporting the convergence of these standards through incorporation of the IFRS in the US financial system (Financial Accounting Standards Board, 2012a). This implies that the US has been increasing exploring adopting IASBs IFRSs, although there have been issues such as the fair value issues in IFRS and the cost of implementation that have slowed the progress. The IASB equivalents of the FASB original pronouncements As noted above, IASBs IFRS takes a principle based approach to accounting standard setting as compared to FASBs pronouncements which are viewed to be much stricter. In essence therefore, though IASB and FASB may address similar accounting concepts their approach to it may be different. It is these IASBs equivalents to FASBs pronouncements that bring the differences between GAAP and IFRS standards. Evaluating the FASBs original pronouncements and IASB, the manner in which accounting concepts are approached can be noted. These are: whereas IASBs IFRS requires that inventory costs of spoilage and idle capacity be excluded from the cost of inventory, FASBs GAAP does not; IFRS requires yearly comparison of financial statements unlike US GAAP which only views comparisons as desirable but require three year comparisons; IFRS permits but does not require reporting of comprehensive income unlike US GAAP which requires it; IFRS classifies liabilities as non-current if refinancing is complete before the date of the balance sheet unlike GAAP which classifies it as so, if refinancing is completed before the financial statements are issued; and prohibition of extraordinary items from the financial reports by IFRS unlike GAAP which permits but to a restricted items which affect profit and loss (Deloitte, 2004; FASB Report, 2002). Other accounting concepts that differ between IASB and FASBs original pronouncements are that IFRS requires that LIFO method of determining inventory cost be prohibited in IAS 2, unlike US GAAP which permits LIFO in SFAS 151, and that IFRS requires reversal of inventory write downs if given criteria are met unlike US GAAP which prohibits it. In addition FASB permits that inventory at net value be measured even if it is above cost unlike IFRS which restricts this to producers and broker-dealers inventories. FASB classifies the interest received and paid as operating activity in the cash flow statement unlike IASB which may classify it as financing, investing or operating activity. This leaves room for a number of interpretations. Furthermore, though FASB excludes overdrafts from cash, IASB includes it if it forms a critical and integral part of an organizations cash base or cash management (Deloitte, 2004; FASB Report, 2002). Other IASB equivalents to FASB pronouncements are enumerated as shown below (Deloitte, 2004; FASB Report, 2002): -IFRS restates previous financial statements in the event of non-mandated changes in accounting policy, unlike FASB which includes cumulative effects current financial statements net loss and profits -IASB uses change in estimated method to evaluate changes in depreciation of assets, unlike FASB which used change in accounting policy that is the net profit or loss cumulative effect. -IASB uses cost recovery method for construction contracts when the completed percentage cannot be determined for sure unlike the USA GAAP which uses completed contract method -IASB does not recognize deferred tax due to the an asset or liability tr ansaction that doesnt affect accounting or taxable profit and is not a business combination in IAS 12 unlike the US GAAP recognizes this these through its lack of initial recognition exemption as addressed in SFAS 109. -US GAAP has special exemptions due to the provision of deferred tax such as leveraged leasing, intangible developments in the gas and oil industry and undistributed earnings -IASB uses a tax rate that is substantially enacted to measure deferred tax liabilities and assets, which can be left to a lot of interpretations, unlike FASBs enacted tax rate which is sure and consistent -IASB uses rate applicable to undistributed earnings of an organization to measure the deferred tax on those earnings , unlike FASB which uses the higher of the tax rate between the one applicable to undistributed profits and the one applicable to distributed profits as addressed in SFAS 109 -IASB recognizes expense for share-based payment based on fair value of the payment whereas FASB recognizes this based on intrinsic value at grant date -IASB measures business combinations on the date of the acquisition whereas FASB does this on the date of consummation or closing date -IASB requires that recognizing a liability prior to acquisition restructuring be only if the one being acquired recognizes it under IAS 37, this is unlike FASB which recognizes it if the acquisition has already began -IASB recognizes in process RD as an intangible finite asset or good will, unlike FASB which recognizes it as expense How MSA Program prepares student for professional Accounting A Master of Science in accounting program is very important for anyone who intends to pursue an accounting career in the future. This program prepares a student by providing knowledge on the various accounting principles that need be applied in accounting profession. It also makes a student be aware of the various accounting standards that are existing in the world, how each differ, and how accounting records and done in each. In addition such a program provides analytical and critical thinking abilities. In addition, it offers a global perspective on accounting practices and business issues and provides a framework for effective development for team building and leadership skills, and ethical decision making in business. Lastly it will enhance interpersonal and communications skills through interactions which seek to learn ways of solving problems and issues in the accounting and finance realm. All these are critical for a career as an accountant. Conclusion This paper has discussed the history of the FASB and IASB boards and their relationship and has looked at IASB equivalents to FASB original pronouncements. It has shown that standardized management accounting and controlling concepts that transcend national boundaries are increasingly needed with concern on the need of an internationalized Accounting and financial reporting standard to help in comparing of financial statements of countries from different countries and also to make it efficient and less costly for multinational companies when they are conducting financial reporting of their performance. IASB and FASB have made tremendous progress thus fur in their bid to converge the global accounting standards.

Impact of Health Inequality in the UK

Impact of Health Inequality in the UK According to the NHS (2013) the UK is perceived as healthier that it has ever been in its history. This is mainly due to the enhancement of life expectancy, the eradication of diseases, and the advantages brought by public health reforms and technology. However, the problem of health inequalities remains omnipresent. Even if the health of the population is improving, the health of the poor or those less well-off is either improving really slow or it gets worse. This is a main challenge for the policy makers, who see that even though their interventions work, they fail in some sections of the population. Health inequalities in the UK To understand the impact of health inequalities, we need to start from the beginning. Economic and social changes, the downfall of manual work, the development in women’s employment, as well as migration patterns and the change of the family structure have modified the population’s nature. Additionally, the NHS (2013) believes that these changes also affect the data about health. They also add that occupation-based classification attracts social inequality in Britain. Moreover, living standards improve the higher one moves on the social ladder, but so do a range of people’s wellbeing factors, such as education, employment opportunities and, last but not least, health. Researchers believe that in an intricate society as Britain, there are â€Å"a number of axes of social differentiation† (Anthias (1990) as cited by the NHS (2013)). These refer to ethnicity, gender, sexuality, age, area, community and religion. Furthermore, it is believed that these classifications are linked but represent separate dimensions of inequality. Exposure to racism is a major factor why the wider population is disadvantaged, and this can take and additional effect on the health of black and Asian communities (Karlsen, 2002). (NHS, 2013) The table provided illustrates a pathway, in the same time giving examples of determinants or factors that operate at different stages along the way. It runs from social structure to health and wellbeing. As it can be seen, education impacts on a person’s health and wellbeing through social position and intermediary factors that are associated with it. Besides the environmental and behavioural factors (housing quality, exposure to smoking) the table also presents health and social services among the intermediary factors. These not only have a strong role in preventive care, but they also contribute so reducing the effects of illness and injury on health. We need to keep in mind that the figure does not provide a complete picture. It shows examples from a key set of pathways. This can refer to poor health and disability which can affect an individual’s socioeconomic circumstances, which influences health and all the way to social position. In addition, due to a person’s social standing, which can alter access to societal resources (education and job opportunities) and exposure to risks, this has a strong relation with health over time and across different diseases. In order to make sure that health inequalities are eradicated, the NHS (2004) comes up with a series of changes that can be applied. Attention needs to be given to the baseline data collected and compare it within and across the New Deal for Communities. Moreover, the planning agenda needs to be more focused towards local health and make sure that goals are realistic and measurable. Last but not least, planned activities need to be specified, resourced and targeted towards change. However, David Buck (2014) states that reducing health inequalities should not be left only to local authorities. Although they have an essential role to play when dealing with these issues, Buck proposes a joint commitment by the leaders of communities on how they approach and deal with this situation by using the â€Å"big levers: commissioning, incentives and accountability†. Further, if health inequalities are not solved, it can have disadvantages not only on the population, but also on the economy. The Marmont Review (201) as cited by Jane Dreaper (2010) states that inequality in health accounts for  £33bn of lost productivity every year. She also advises the NHS to start spending more on prevention than the 4% it currently does, so as to provide more help to those who need it. Challenges When identifying and analysing challenges I have decided to focus on diet and lifestyle factors. Diet and nutrition The Department of Health (England) states that food poverty is â€Å"the inability to afford, or to have access to, food and to make up a healthy diet†. The Faculty of Public Health (2009) also adds that the poorer an individual is, the worse their diet and the more diet-related diseases they suffer from. This represents a risk which can backfire to diseases such as cancer, coronary heart disease and diabetes. It has been found that poor diet accounts for 30% of life years lost to early death and disability (National Heart Forum, 2004). Inequality in health has a strong correlation to food poverty. People with low incomes suffer from poor diets, due to low intakes of fruit and vegetables, and also dental caries among children, to name a few. Already the government is trying to solve the issue, but the actions needs to be more than health professionals giving advice to individuals. The â€Å"food environment† needs to change, referring to accessibility, affordability and culture. By strategically including public health professionals in key areas and developing programmes, the barriers to healthy eating can be broken down and nutrition improvement can be achieved (Faculty of Public Health, 2009). Some barriers to healthy eating have been tackled and presented. One of the main factors is the low income and debt. This can restrict an individual’s access to fresh fruit and vegetables, which are normally more expensive. Additionally, this is influenced by the poor accessibility to affordable healthy foods. In disadvantages neighbourhoods, shops are starting to close down, and the construction of supermarkets out of town proves to be difficult due to transport links and impossibility to pay for the fair. Furthermore, foods which are high in fat, sugar and salts are cheaper and more available, making it one of the biggest factors of poor nutrition. The same findings have been stated by Hillary Shaw in her study conducted in Birmingham (Hillary Shaw 2012). Exercise The Health Survey of England conducted a survey in 2008 regarding participation in all types of physical activity at work, and during leisure time. The results showed that social class is a great factor in participation, but it differs regarding gender. (Health Survey for England 2008) This measurement includes physical activities carried out during work. However, when this is excluded, a connection between physical activity and income is observed among men, but not women. This can also be explained by active transport, such as walking or cycling, since people on lower income may walk or cycle more due to not owning a car or affording public transportation. Furthermore, The Active People Survey conducted in 2011/12, with 500 participants, found a relation between socioeconomic factors and participation in sport. The figures in the table below use the notations of the National Statistics Socio-Economic Classifications (NS-SEC). From the findings, we can observe that 43% of the adults in groups 1 and 2 take part in sport for at least 30 minutes once a week or more, compared to 27% of adults in groups 5-8. (Active People Survey 2011/12) The National Institute for Health and Clinical Excellence (NICE) affirmed that the figures reported from the above surveys are influenced by the built and natural environments people live in. People from lower social standings tend to live in areas or neighbourhoods which have poor access to environments that support physical activities (parks, gardens or safe areas), and tend to live near busy roads. To add, people from lower socioeconomic groups tend to live in areas that do not present a framework for public transportation, therefore they rely on walking or cycling for transport and to access employment (The Marmont Review 2010). More, fear of traffic can be another factor in allowing children to play outside, walking or cycling. The Institute of Public Policy Research (2002) revealed that children in the 10% most deprived wards in the UK are more than three times as likely to be pedestrian casualties as children in the 10% least deprived wards. Affordability may also be a barrier to taking part in sports and activities. This is due to gym membership costs that are out of the range for many people with low incomes. The Health Survey for England (2007) showed that 13% of men and 16% of women cite lack of money as a barrier to exercise. Even though, taking part in activities such as walking or hiking are less costly, 45% of men and 34% of women stated that work commitments represent another obstacle to being active. Therefore, people from a lower social standing may not have the money and the time to take part in physical activities. One example for these findings is provided by Rowenna Davis (2011). She compared two neighbourhoods in Glasgow which are close to one another, but differ in every way: Jordanhill, a posh area, and Parkhead, a poor neighbourhood. The ladder area is known for having worse housing, not enough parks and poor transportation links. Moreover, researchers believe that children living in this area are more likely to start smoking, drinking and having a poor diet. Smoking People in poorer social classes are believed to die sooner due to a series of factors. The dominant factor among men is smoking, accounting for nearly half of the difference in risk of premature death between the social classes. Additionally, smoking is more concentrated in Britain’s poorest families, with low income lone parents having the highest rates of smoking. This is also influences the high rate in illnesses in this category, such as cancer and heart disease (NHS 1999) Smoking during pregnancy also has its say in this issue. It not only hurts the mother, but also the unborn child. The highest rates have been recorded among expectant mothers under the age of 0 and women who have left school at the minimum leaving age and with no educational qualifications. These results show to be three times higher among women from a bad social standing than women in the rest of the categories (NHS 1999). Leaders There are many charities nowadays that are trying to solve the health inequality prove by helping those who need aid. One of the charities I have identified is the Gleaning Network UK. This initiative’s goal is to save thousands of tonnes of fresh fruit and vegetable which are wasted on UK farms. These crops cannot reach the market because they fail the cosmetic standards of due to overproduction. The Gleaning Network UK uses teams of volunteers, local farmers and redistribution charities in order to salvage this food and give it to those that need it. In 2013, they have saved 48 tonnes of produce which were made into 200,000 meals that helped communities around 6 major cities (Gleaning Network UK, 2014). The British Heart Foundation is also fighting to stop health inequalities, by providing support to those who smoke and want to quit, with the help of â€Å"No Smoking Day†. This is one of the UK’s biggest annual health awareness campaigns which creates supportive environments for everyone and provides sources of help and advice. Already in 2013, 20% of the smokers aware of this campaign made an attempt to stop smoking, reaching an estimate of 1 million quitters (No Smoking Day website 2014). Regarding exercise and physical activity, one of the most prolific charities I have found is the Right To Play. They believe that play and exercise if a tool for education and health, so volunteers teach children and youth that through sport one can be taught about values and goals. Their vision is â€Å"to create a healthy and safe world through the power of sport and play†. Even though the organisation works at a global level, it helped many communities in the UK to start taking up sports and leading a healthier life (Right to Play website 2014). Recommendations Improving people’s lifestyles and eradicating food poverty need to be top priorities for primary care organisations and local authorities. Moreover, collaboration of organisations, charities and councils need to focus on developing strategies which will reduce barriers to a healthy life. One of the first recommendations drawn from the charity examples from before is to establish a local â€Å"food poverty partnership† with organisations including health services, local authorities and voluntary organisations to develop a local food poverty strategies. One successful example is the Cyrenians in Edinburgh, Scotland, a charity which started an initiative of â€Å"turning waste into opportunities†. Their aim is to get food waste down to zero, by working with local restaurants and shops and socially disadvantaged people from different communities. The food that the eateries and shops do not use anymore is donated to charities which will prepare meals for those who need it. Moreover, they provide jobs for those who also wish to work in the fields of collection and cooking (Cyrenians 2014). The next recommendation focuses on working with local communities and understanding their priorities, barriers and opportunities. With the help of community meetings and surveys, healthy living can be promoted. One of the best examples in this case is the Good Gym organisation. This charity encourages people to combine their exercise routine with volunteering, matching busy workers with elderly â€Å"coaches† who receive their paper or deliveries in exchange of an incentive for their weekly visitors to keep on running. The Good Gym works with the NHS, charities and local community centres, and talks to people from poor neighbourhoods trying to understand their situation and what can be done. As a result, the foundation organises monthly group runs in east London, performing useful activities along the way. Up till now, the members have distributed flyers for a local hospice, tidied up community gardens and hauled compost on to a school roof (Barkham 2012). When tackling smoking, care providers, local councils and the organisations involved need to put together treatments that will prove to be effective. The GP should consider holding brief interventions to those trying to give up smoking, also providing advice, self-help materials and suggestions for more intensive support. Individual behavioural counselling will be essential when lending a help for those seeking motivation to quit. Additionally, mass-media campaigns need to become the main means of sending the message of â€Å"stop-smoking† across, by using radio commercials, internet and TV ads. The same strategies have been used by the NHS with their â€Å"No Smoking Day† campaign. This movement has recorded an increase of 10% over the last 4 years of those who want to smoke.

Electromagnetic Radiation Features

Electromagnetic Radiation Features 2.1 Electromagnetic radiation Electromagnetic radiation consists of waves of electric and magnetic energy oscillating through space at the speed of light (OET, 1999). The electromagnetic spectrum is an arrangement of various electromagnetic energy in the forms of particles and waves. These form of energy are characterized by frequency and wavelength. The wavelength is the distance per seconds covered by an electromagnetic wave, while the frequency, the number of oscillation of electromagnetic waves for one second. Figure 2.0.1 bellow shows an electromagnetic spectrum. Figure 2.0.1. Electromagnetic spectrum The electromagnetic spectrum shows the arrangement of electromagnetic sources based on their frequency and wavelength. Below is Table 2.0.1 which describes the radiofrequency sources and their allocated bands and frequency ranges. Table 2.0.1. Characteristics and frequency bands of radiofrequency field sources Band Description of signals Frequency range FM Frequency Modulation 88’108 TV/DAB Television (analogue) DAB (Digital Audio Broadcasting) 174’223 TETRA Terrestrial Trunked Radio 380’400 TV Television (analogue and digital) 470’830 GSM DL Global System for Mobile Communications from base station to mobile phone 925’960 DCS DL Digital Cellular System 1,805’1,880 UMTS DL Universal Mobile Telecommunications Service 2,110’2,170 Wi-Fi Wireless Fidelity, IEEE 802.11 standards 2,400’2,500 The most important application of electromagnetic energy is in the use of radio broadcasting, mobile telephony, microwave application and satellite communication as reported by Kelly (2011). Others include magnetic resonance imaging (MRI), Microwave ovens, radar, industrial heaters and sealing (Kelly, 2011). 2.2 Radio waves Radio-frequency (RF) is a part of the arrangement of electromagnetic energies in terms of their frequencies from 3 kilohertz (3 kHz) to 300 gigahertzes (300 GHz) (Kelly, 2011). Radio-transmitters are devices that serve as transducers for converting electrical current into electromagnetic waves. The knowledge of the presence of electromagnetic field was first discovered as far back as 1887 when a Physicist proved experimentally that electromagnetic fields can be produced and detected in space. This phenomenon was predicted three years earlier by Clarke Maxwell (1831-1879). A radio transmitter communicates with a receiver via radio waves when electric charges moves up and down the transmitters antenna and are detected when the electric charge oscillate up and down a receivers antenna. In the process, when the charges moves, they produce magnetic fields. The resulting changing electric-magnetic fields (electromagnetic waves) are able to travel long distances through an empty space (Vacu um). The ability of a transmitter to send signal to a receiver or another transmitter nearby depends on the oscillation of the charges up and down its antenna at a particular resonant frequency. 2.3 Characteristics of radiofrequency (RF) antenna There are a number of physical parameters and principles that define the type of wave and intensity of the radio waves generated and broadcasted into the environment. These parameters are relevant in understanding the behavior of the antennas. These are the antenna element, element array, gain or directivity, radiation pattern, radiation intensity, beam-width and power density. 2.3.1 Antenna Elements The antenna element is a basic unit of the antenna. They may exist as individuals or as a group of elements. There are three most common types: dipole, monopoles and loop. A dipole antenna is most commonly a linear metallic wire or rod with a feed point at the center. It has two symmetrical radiating arms. A monopole antenna on the other hand has a single radiating arm. A number of authors have performed calculation and measurements on the pattern generated by these field on mobile handset in air and also against the head (Jensen Rahmat-Samii, 1995) ; (Okoniewski Stuchly, 1996) and (Lazzi, 1998). Other works on wireless devices such as cellular telephones using monopole antenna has also being reported in literature (Luebbers, 1992). An interesting application of loops is the wireless telemetry for medical devices and used for the first pacemaker (Greatbatch Holmes, 1991). 2.3.2 Antenna Arrays To yield a highly directive patterns, multiple antennas or elements can be arranged in space, in various geometrical configurations to yield a pattern (Stutzman Thiele, 1998); (Bucci, Ella, Mazzarella, Panariello, 1994) ; (Balanis, 2005); (Elliott, 2003) and (Mailloux, 1994). This antenna configuration are called arrays. The field from an array can add constructively or destructively in others. When well-engineered, the array can be used to control the beam by changing the phase of the excited currents of the individual elements (Elliott, 2003) ; (Dolph, 1946) ; (Safaai-Jazi, 1994) and (Shpak Antoniou, 1992). By so doing, an optimum radiation beam can be generated. The geometry of the arrangement of the element also affects the performance. Other factors are distance between the elements, amplitude of the excited currents, phase excitation and radiation pattern. 2.3.3 Directivity and Gain Another parameter used to describe the directional properties of an antenna is the directivity or gain. The directivity of an antenna, is a figure of merit that quantifies the antenna directive properties by comparing them with those of a hypothetical isotropic antenna that radiates the same total power as the antenna being characterized. Antenna such as dipoles and loops generates omnidirectional pattern, (McDonald, 1978) and (Pozar, 1993) derived a formula for such. The gain of an antenna is a measure that takes into account the efficiency of the antenna as well as its directional capabilities. The total antenna efficiency accounts for losses at the input terminals and the structure of the antenna due to reflection, conduction and dielectric losses. 2.3.4 Radiation Pattern       Besides the parameters described above, the radiation pattern is the property used to describe the resulting shape of the beam generated. Radiation or an antenna pattern is a mathematical function of the antenna that describe the space coordinates (Balanis, 2005). The main beam is the region where the radiation is strongest and the other directions forms the side-lobes. The half-power beam width is the measure of the direction of maximum radiation. The beam width or Half-Power Beam width (HPBW) is the width of the power pattern at the location where the beam is 3 dB below its maximum value (half-power points) or the location where the field is 1/Ã… ¡2 of its peak. It is often used as a trade-off between it and the side lobe level (The ratio of the radiation intensity of the largest side-lobe to the maximum radiation intensity). The HPBW varies inversely as the side lobe level. The most common resolution criterion states that the resolution capability of an antenna to distinguish betw een two sources is equal to half the first-null beam width (FNBW/2), which is usually used to approximate the half-power beam width (HPBW) (Kraus, 1996) and (Kraus Marhefka, Antennas, 2002). 2.3.5 Polarization Furthermore, the generated wave can oscillate up and down, left and right or characteristic between these. These behavior describe the kind of polarization the wave exhibits. Polarization of a radiated wave is defined as that property of a wave in a time-varying direction and relative magnitude of the electric field vector. In general, however, when the shape of the electric field appears in the form of an ellipse, the polarization is described as elliptical. When the shape appear linear or circular, the polarization is described as such. The polarized radiated wave by the antenna can also be represented on the Poincares sphere (Balanis C. A., 1989) ; (Poincar ´e, 1892) ; (Deschamps, 1951) and (Bolinder, 1967). 2.3.6 Radiation Intensity Another important property of the antenna is the radiation intensity. The radiation intensity is the power radiated per unit solid angle subtended by the antenna. It is the property of the far field. The radiation intensity is obtained by multiplying the density by the square of the distance. The power pattern is also a measure of radiation intensity. To be able to obtain the total power density, one need to integrate the radiation intensity. 2.3.7 Power Density Finally, the radiation power density describes the power associated with an electromagnetic wave. The power density is the total power crossing a closed surface by integrating the normal component of the Poynting vector over the entire surface. 2.4 Electromagnetic field around an antenna An electromagnetic field is the region created around a source of electromagnetic radiation. An antenna is a device which changes electrical charges or current into electromagnetic waves into space. The distribution of RF energy from an antenna was found from literature to obey a directional pattern and varies with distance from the antenna. The fields created around an antenna can be grouped into two: 2.4.1 Near Field The near field is the region around an antenna such that; the electric and magnetic fields are decoupled, quasi-static and are not uniform. And the impedance which is the resistance in air and the power associated with the field varies with distance. 2.4.2 Far Field The far field on the other hand have plane fronts which do not depend on the shape of the source but rather unchanging. The radiated power decreases inversely with distance from the antenna theoretically. The electric and magnetic fields are uniquely defined by approximately a constant impedance of the medium. Figure 2.0.2 below illustrate the field regions around an antenna. Figure 2.0.2. Electromagnetic field regions around a typical antenna 2.5 Advances in field modeling A modeling is a good approximation of a problem to a real world solution. There are various mathematical modeling methods available in literature to date (Sarkar, Ji, Kim, Medouri, Salazar-Palma, 2003) ; (COST-231, 1999) and (Correia, 2001). Extensive theoretical and experimental research on electromagnetic field Levels has been carried out and reported in literature (Lin, 2002) ; (Cicchetti, 2004) and (Nicolas, Lautru, Jacquin, Wong, Wiart, 2001). Currently, the studies in electromagnetic fields can be grouped into two dominant channel modelling approaches: theoretical and empirical (Rappaport, 2002). While theoretical models depend on the knowledge of the physical laws of the wireless channel, such as the electrical properties of the ground, empirical models are based on actual radio frequency (RF) measurements of wireless channels. Furthermore, one can regroup it into Monte Carlo, Empirical and Physical models (Rappaport, 2002). Monte Carlo method are statistical in nature and m ake use of statistical and distribution functions such as channel characteristics of radio-transmitters and ray-optics. (Okumura, Ohmori, Kawano, Fukuda, 1968) Found out from measurement that for a situation where one cannot have a line of sight with the transmitter, the fading (attenuation) of the received voltage approximates relay distribution. Okumura also developed a correction factor to be used together with the data to correct for the field strength. When Okumuras measured results were averaged, the results showed properties of a lognormal distribution. (Okumura, Ohmori, Kawano, Fukuda, 1968) And (Mogensen, Eggers, Jensen, Andersen, 1991). The style of settlement and nature of buildings also affect the propagation of the radio waves when traveling from a source into the environment. Also random variation of building also contributed to loss of propagation of the waves. Some earlier work suggested that radio waves propagates over buildings and are diffracted down to street levels (Parsons, 1992). To be able to obtain reliable statistics, a lot more of measured data was required. Diffraction is when the path of the beam is obstructed by surface of irregular shape edges. Diffraction methods were developed and used to account for diffractions at rooftop (Ikegami, Yoshida, Takeuchi, Umehira, 1984). Variations in building height contributed to the shadow loss of propagation over low buildings. The most general approach uses numerical integration of physical optics integrals (Walfisch Bertoni, 1988) and (Bertoni, 2000). Measurement has shown that Monte Carlo methods need to consider the effect of trees (Mogensen, Eggers, Jensen, Andersen, 1991), (Rizk, Mawira, Wagen, Gardiol, 1996), (Vogel Goldhirsh, 1986) and (LaGrone, 1977). Trees are able to attenuate the signal to the order of 10 dB (Vogel Goldhirsh, 1986). The Monte Carlo methods even though are good when adequate measured data is used, suffers from modifications to the buildings and terrains and are very expensive to carry out. Empirical methods make use of information gathering on the basis of systematic experimentation instead of making use of logic or mathematics. The empirical model uses extensive measured data and analysis tools to formulate relationship between parameters of interest. Measurements have shown that a simple two-ray model consisting of the direct and the ground-reflected ray was sufficient to predict the path gain (loss) for propagation over a flat earth (Rustako, Jr., Owens, Roman, 1991) and (Xia, Bertoni, Maciel, Lindsay-Stewart, Rowe, 1993). Reflection occurs when the wave from a source hit an object whose dimension is large as compared to the wavelength of the wave. The path loss represents the signal attenuation in decibel (dB). The path loss is the difference between effective transmitter and receiver power. Most published work concerning outdoor propagation depends on free space and two-ray models (Pande, Choudhari, Pathak, 2012), (Willis Kikkert, 2007), (Neto, Neto, Yang, Gl over, 2010). The free space model assumes that both transmitter and receiver, use line-of-sight communication with no obstruction or reflection of any form. The free space model obeys the relation: (2. 1) Where f is the frequency in MHz and d is the separation distance between the transmitting and receiving antennas in meters. The receiver power has been found to falls off as the square of the transmitter-receiver separation distance. The receiver power decays at the rate of 20dB per decade. When the effect of ground ray reflection is considered, a Plane Earth model was used. The model is given as: (2. 2) Where d is the distance as above and and are the elevations of the transmitter and receiver heights in meters respectively. The separation distance (d) in this model is assumed to be much larger than and .In our real environment today, there are obstruction everywhere and the propagation of the electromagnetic waves are affected by it (Mao, Anderson, Fidan, 2007). The radio signals in our environment are attenuated by reflection, diffraction and scattering. Scattering occurs when an object in a medium are smaller as compared to the wavelength of the incoming wave. To be able to account for location characteristics and the impact of vegetation, it was found in literature that the average signal power decreases logarithmically with distance (Rappaport, 2002). To be able to estimate the path loss due to real world approximation, a log-distance model was developed. The average path loss for a typical distance between a transmitter and a receiver can be represented as an expression of distance by using the exponent n. The path loss is given as (Liao Sarabandi, 2005): (2. 3) Where is the path loss in dB at a reference distance and n is the path loss exponent that represent the rate of the path loss decrease as a function of distance. The value n also characterizes the propagation environment. Table 2.0.2 below summarizes the characteristic of the exponent n in the environment. Table 2.0.2. Characteristics of typical propagation environments Environment Path loss exponent values (n) Free space 2.0 Urban area, cellular radio 2.7 to 3.5 Shadow Urban cellular radio 3.0 to 6.0 In-buildings, line-of-sight 1.6 to 1.8 Obstructed in buildings 4.0 to 6.0 Obstructed in factories 2.0 to 3.0 The reference distances from research was taken to be between 100 m to 1 km depending on the height of the transmitter. The International Telecommunication Union (ITU) recommended that in a situation where majority of the signal propagates through trees or vegetation, the ITU-R model can be used (Rappaport T. S., 1996). (2. 4) Where the frequency used was between 200 MHz and 95 GHz. One of the most important fully empirical prediction method was conducted by (Okumura, Ohmori, Kawano, Fukuda, 1968). Okumuras method was based entirely on an extensive measurement in Tokyo city. Okumura developed a set of curves given the median attenuation relatively to free space in the urban area over a quasi-smooth terrain. From these curves, Okumura deduce from the graphs a simple power law which was a function of the environment and it characteristics. The model was applicable to frequency range between 200 MHz and 2 GHz and covers a distance of 100 km. Okumuras data was further modified by (Hata, 1980) who made it into a series of graphs. However, other methods disagree with the predictions of the Okumuras methods. Others have also tried to improve the method by applying building density (Kozono Watanabe, 1977) but was rejected by the scientific community. The Okumura-Hata model, together with related corrections was found to be one of the most common and single model used in designing real systems. Lee in 1982 came out with a power law model which was based on measurement and takes into account the variation in terrain (Lee, 1982). The model was environment specific because it was based on the assumption of the characteristics of the environment. It will be very difficult to tell which environment characteristics one need to use since the environment varies from one country to the other. Even though empirical method was easy to implement and their ability to include all environment-related factors that affect the propagation of radio waves in practice (Rappaport T. , 2002), they suffer from parameter ranges; the environment must be classified which may vary from one place to the other .the method also do not provides insight into propagation mechanism and analytical explanations. The Physical model method attempt to produce deterministic field strength at specified points. (Ikegami, F.; Takeuchi, T.; Yoshida, S., 1991). The model makes use of characteristics of the environments, physical optics and other theories to account for the intended parameter of interest. A careful assessment of the exposure of urban populations to electromagnetic fields requires the use of deterministic models that take into account the interferences caused by the buildings in the propagation of the field. Deterministic models were developed to account for terrain in the absence of buildings based on geometric theory of diffraction (Bullington, 1977), (Luebbers R. J., 1984) and (Lampard Vu-Dinh, 1993). Other methods such as parabolic equation method (Janaswamy Andersen, 1998) and (Levy, 1990) takes the detail terrain profile into account. The method uses detail map of an area taking into consideration building configurations and using a ray optics to trace the waves. There are 3-D (three dimensional) ray tracing models that are able to accurately estimate site-specific propagation situations (Catedra, Perez, Saez de Adana, Guiterrez, 1998). Although it accounts reasonable well for close in variation of field strength, it suffers from unrealistic assumptions, theories and underestimate in some cases (Saunders, 1999). Other works also uses numerical methods such as method of moments (MOM) to analyze the electromagnetic field of antennas (Johnson, Shin, Eidson, 1997), (Wanzheng, Yan, Anmin, 2000), (Povinelli DAngelo, 1991), (Lou Jin, 2005) and (Tofani, dAmore, Fiandino, 1995). However, these Methods require higher mathematical and programming skills such as large sparse matrix solution as well as more computer resources such as larger memory and multiple CPUs than the analytical method (Johnson, Shin, Eidson, 1997). A semi-analytical treatment has been carried out for cases where the horizontal separation between the base station and first row of building s is knownand all the buildings are of the same height (Xia, Bertoni, Maciel, Lindsay-Stewart, Rowe, 1993), (. Bertoni Maciel, 1992). From the above analysis, it was evident from literature to date that there is no one method which will be able to predict accurately well and also help us understand and make meaning of the physics involved in the process of study. This research work focuses on the need for a hybrid model (Semi-Empirical) which will achieve a good level of accuracy and also help us understand the physical interaction of the parameters involved and also serve as an advancement on this field. 2.6 Advances in measurements The natural electromagnetic energy comes from terrestrial and extra-terrestrial sources such as electrical discharges during thunder storms in the atmosphere and radiation from sun and space. It is of interest to note that the blackbody radiation from a person in the RF-band is approximately 3 mW/m2. The man-made source originates from mainly telecommunication and broadcasting services in the environment. There are several methods developed to assess the electromagnetic fields (EMF) exposure level in literature. One of them was the use of a personal exposure measurement methods (Viel, Cardis, Moissonnier, Seze, Hours, 2009), (Urbinello, Joseph, Huss, 2014), (Bolte Eikelboom, 2012), (Urbinello, Huss, Beekhuizen, Vermeulen, Rà ¶Ãƒ ¶sli, 2014), (Radon, Spegel, Meyer, 2006) and (Frei, Mohler, Bà ¼rgi, 2009). Another method is the used of stationary measurement approach (Bà ¼rgi, Frei, Theis, 2010), (Calin, Ursachi, Helerea, 2013), (Pachà ³n-Garcà ­a, Fernà ¡ndez-Ortiz, . P aniagua-Sà ¡nchez, 2015), (Ozen, Helhel, Colak, 2007), (Korpinen Pà ¤Ãƒ ¤kkà ¶nen, 2015) and (Verloock, Joseph, Goeminne, 2014) where measurement is made at a define period of time such as 6 minutes averaging. The 6-minute averaging time comes from the time constant for the thermoregulation of the body (ICNIRP, 1998) to occur. FM and TV broadcast transmitters, GSM and UMTS base stations are important sources of RF EMF in terms of exposure level in the environment. In general, FM and TV broadcast transmitters were installed in places far off distance from the city center in the past but in todays world, they are installed within our communities. In 1980, Tell and Mantiply published a study of RF fields measured at 486 sites across 15 major metropolitan areas in the USA which at that time, accounted for nearly 20 % of the nations population of 226.5 million people (Tell Mantiply, 1980). The measurements covered the low VHF TV (54-88 MHz), FM radio (88-108 MHz), high VHF TV (174 -216 MHz) and UHF TV (470-806 MHz) bands. They reported a median wideband time-averaged field level of 0.005 mWcm-2, with an estimated 1 % of the population exposed to fields with power densities of 1 mW cm-2. In addition, the fields from FM radio broadcasts were clearly dominant over the fields from the other three bands. Typically for High-power broadcast transmitters, the effective radiated power (ERP) was 250 kW per channel for FM radio and 500 kW per channel for television. The antennas were mounted towards the top of a 300 m mast. For medium-power broadcast and telecommunications transmitters, the transmitted powers were in the region of 100-200 W per channel. The exposure to the general public was very small relatively to people living in the immediate neighborhood of medium and short-wave stations (Jokela, Puranen, Gandhi, 1994). People working in FM and TV towers which are near to high power FM or TV broadcast antennas were exposed to high levels in the range of 50 to 800 MHz (Jokela Puranen, Occupational RF exposures, 1999) and (Hansson-Mild, 1981). Other studies have been carried out in the domains of exposure field measurement by (Viel, et al., 2009a), (Viel J. , Cardis, Moissonnier, R., Hours, 2009b) and possible consequences of human exposure to such fields(Hossmann Hermann, 2003). A study of ambient RF fields conductedmostly outdoors in Gothenburg, Sweden reportedan average wideband power densities of between 0.04and 0.05 mW cm-2 (Ahlbom, Feychting, Hamnerius, Hillert, 2012).European studies reported generally, in the five-country analysis, the totalexposures were lowest in the urban residential environment(range of means 8.5E-03 to 1.45E-02  µW cm-2). The results for a set of African countries was qualitatively and quantitatively similar to the results of RF measurement surveys conducted in the Americas, Europe and Asia (Rowley Joyner, 2012) where the global weighted average was 0.073 mW cm-2. The mean for the selected South Africa n data set was 0.016 mW cm-2. Some of the conclusion drawn was that the signal strengths for the cellular bands was unchanging in both time and across countries. Even though introduction of 3G and 4 G services are on the increase, the field levels are log-normally distributed and more data points makes the FM signal strengths relatively constant. In addition to these findings, several studies have reported that residential (and outdoor) fields from broadcast and cell downlink sources are lower in rural areas compared with fields in urban and suburban areas (Breckenkamp, et al., 2012), (Viel, et al., 2009a) and (Joseph, Vermeeren, Verloock, Heredia, Martens, 2008). Cancer has been the primary concern among populations in the immediate vicinity of broadcast transmitters. Scientific evidences point toward heating effect from high levels of exposure, and most safety limits are based on it. Among these are the exposure limits proposed by the International Commission for Non-Ionizing Rad iation Protection (ICNIRP) (ICNIRP, 1998) or Institute of Electrical and Electronics Engineers (IEEE) (IEEE, 2005) to prevent such effects (WHO, 2006).There is little scientific evidence on the risks associated with long-term exposure to low levels of RF EMF (ICNIRP, 1996). In 2012, the International Agency for Research on Cancer classified RF EMF as possibly carcinogenic (Group 2B), based on studies on mobile phone usage (IARC, 2012). Mobile phone usage has increased tremendously, with about 6.8 billion subscriptions by the end of 2013 (ITU, 2013) and nearly 7 billion cell phone subscribers in 2014 (ITU). Statistics show that as at May 2008, the number of mobile phone users in Ghana was well over 8 million but as at the end of January 2016, the number of mobile phone users in Ghana rose to 26.09 million, according to the latest figures from the National Communications Authority (NCA). Urban areas are mostly affected by the over population of Base Station Transceivers (BTSs). Their closeness to homes and schools are raising concern about some health risks that might be associated with them (Khurana, et al., 2010). Numerous studies have demonstrated that a very significant part of the human exposure in the radiofrequency (RF) band is due to mobile communications radiation (Bornkessel, Schubert, Wuschek, Schmidt, 2007), (Genc, Bayrak, Yaldiz, 2010), (Joseph, Verloock, Goeminne, Vermeeren, Martens, 2010), (Kim . Park, 2010), (Rufo, Paniagua, Jimenez, Antolà ­n, 2011), (Joseph, W.; Verloock, L.; Goeminne, F.; . Vermeeren, G; Martens, L., 2012a), (Joseph, W.; Verloock, L.; Goeminne, F.; Vermeeren, G.; Martens, L., 2012b), (Rowley . Joyner, 2012). The maximum output powers of a radio channel used in GSM and UMTS networks are 10-40W and 20-60 W, respectively (Koprivica, Neskovic, Neskovic, Paunovic, 2014).It has been shown t

Dr. Strangelove, by Stanley Kubrick :: Dr. Strangelove Essays

  Ã‚  Ã‚  Ã‚  Ã‚  In Dr. Strangelove, Stanley Kubrick took a serious issue and turned it into a political comedy. He was able to illustrate a satire of the hazardous notion of a nuclear war and the insane individuals who were coordinating it, and furthermore, addressed the issue of stereotyping. This movie was created in 1964; today in 2005, we still have nuclear weapons. Yes, the United States and other countries still have nuclear weapons, however, a question does arise, do we still have insane individuals coordinating war plans and security procedures? If you are expecting to find the answer in this essay, do not continue reading for that reason, the answer will not be found in this essay. The reason being is the answer needs to be realized and determined by every individual, not just me. However, if questioned that in Dr. Strangelove was there an individual who was insane and should he have not been placed in command of a military base, then I would have to answer yes there was such an individual. This individual was General Jack Ripper.   Ã‚  Ã‚  Ã‚  Ã‚  I think that it was not coincidental that Kubrick named this individual Jack Ripper, but purposely did so. The real Jack Ripper was a serial killer. Not only does the name fit with the character in Dr. Strangelove, but also the images and actions often associated with the serial killer. Silent and cruel attacks, nighttime, darkness and dense fog are a few images associated with the serial killer. In the movie General Ripper was in a dark office, he ordered Wing Attack Plan R to bombard the Soviet Union with a nuclear bomb before they could respond, and right before killing himself he was in a cloudy/smoky room. The Wing Attack Plan R is my analysis of the silent and cruel killings. The cloudy/smoky room is the dense fog. And finally the darkness of General Ripper’s office fits with the darkness image. What was the purpose of General Ripper when looking at the movie as a whole?   Ã‚  Ã‚  Ã‚  Ã‚  It is my analysis that Kurbrick was not just showing America the stupidity of nuclear war, but was also showing that the United States government often makes mistakes. One mistake, not just in the movie but in life, is the allocating of power to an individual who is not fit, whether mentally or physically, to have this power. When these individuals are allocated this power their actions can have a worldly consequence.

Personal and Social Struggles in The Crucible by Arthur Miller Essay

Although a strict society composed of high morality and disciplinary laws may be necessary for safety, it causes internal conflicts within the individuals. In The Crucible, by Arthur Miller a theocracy in Salem rules and guides the citizens into doing what is â€Å"right†, but eventually backfires due to issues of reputation and jealousy. Society has a lot of influence on the citizens, and with a bad reputation, it is nearly impossible to live in a Puritan society. Salem’s strict Puritanical social structure causes personal struggles for the individuals involved in the events of The Crucible, and then eventually these personal struggles affect the society overall. Abigail’s struggles come from many of her personal desires that are forbidden in her society, causing her to lie. However, this also creates further social problems, such as the initiation of the witch trials. After Betty is stuck in a coma, Reverend Parris questions Abigail about the night in the woods, because he is suspicious and she denies that it had anything to do with witchcraft. Abigail replies to Parris saying, â€Å" We never conjured spirits† (24). Abigail lies to Parris, denies the statement that witchcraft ever occurred, and says that all they did was danced. Witchcraft and dancing both are sins in the society, and she knows that her reputation is at stake and finds the need to lie to look innocent. Parris wants to be sure and calls Reverend Hale to look further into the issue. Once Reverend Hale comes into town, he questions Abigail about the night, and she once again denies everything he asks her. Abigail is being questioned by Hale, and once Tituba ente rs she screams, â€Å" She made me do it! She made Betty do it! She makes me drink blood!† (45). Abigail denies every... ...Proctor deals with issues based on guilt which eventually are brought up in court. Although the individuals’ personal struggles in The Crucible are brought by society, ultimately they affect society as well. Abigail’s personal desires were forbidden in society which brought her struggles, ultimately causing her to lie, and then initiating the witch trials. Mary Warren is unable to keep her personal commitment to John Proctor because of her fear of Abigail and the girls, eventually harming John Proctor. Lastly, John Proctor deals with his guilt over his affair with Abigail, and he confesses in court, but Elizabeth testifies he has not had an affair. All of these personal and social struggles are relevant to our society today because the witch trials are still a very controversial Works Cited Miller, Arthur. The Crucible.

Biometrics :: Science Technology Essays

Biometrics For most people when first hearing the word biometrics, they have an instant reaction to tune out. Just because the term sounds complicated and somewhat boring does not mean that the information behind the term is incredibly interesting and fun! When first discussing the term with others, I too thought it would be a typical boring computer topic. It was not until I began to research the topic, that I saw computers to be intriguing. One of my favorite aspects of the topic is what it initially reminds me of. I could not help but think of spy and other technical movies that show biometrics being used. The term biometrics, refers to the automated methods of categorizing a person, based on their behavioral, and physiological characteristics. What people may not know about biometric systems, is that the basis alone is from natures oldest way of identification. By determining these characteristics in an authentication inquiry, this information can then be saved in reference, for identification to determine if the user can be granted access to any private or secured location. This particular method of recognition is preferred to those such as, passwords, or pin numbers. Although these methods are still commonly used, with biometrics we are able to make sure the person being identified is physically present, and elements the hassle of remembering several passwords. These physiological techniques could include fingerprints, retinal scanning, voice patterning, facial recognitions, DNA analysis along with hand and finger geometry. Biometrics is such a rapidly improving technology, that has been previously used for years in forensics, such as identification, and prison security. While the behavioral techniques include handwriting and voice recognition, gait, and keystroke dynamics. By having these special techniques replacing pins, we are able to feel secure about unauthorized used of ATM’s cellular phones, desktop PC’s, and other personal securities. In addition to these currently password protected areas, biometrics can also replaces keys for automobiles, such as key-less entry. Trust in these areas of secured access, is essential to a happy and healthy environment. Even though there are several ways of detecting identity, the most popular has been the facial recognition and fingerprint matching. These techniques are expected to be added in aid for homeland security identification, at places such as airports, along with helping in reliable travel documents, and preventing ID theft. Along with th e important need for reliable homeland security, biometrics are important in areas such as financial transactions, retail sales, investing, electronic banking, law enforcement, and health and social services.

New grading policy

In the present paper, I would like to provide my arguments against the new grading policy, whose nature is random selection of grades. In fact, there are two points of its fallibility: the fact that it actually measures students’ luck rather than their true achievements and that it destroys the entire purpose of education as the process of gaining knowledge and skills. First of all, it is necessary to define the term â€Å"grading†. According to the Educational Policies Committee, grading is â€Å"the main symbolic method of recording the evaluation of a student’s academic performance† (Educational Policies Committee, 1991). Evaluation, in turn, can be defined as assessment of the value of individual achievements, according to the existing educational standards. Education, according to Fuhrmann and Grasha (1983), is â€Å"the development of knowledge, skills and character of students through continuous motivation† (Fuhrmann and Grasha, 1983, p.156). As one can understand, the new grading policy does not set up the interrelation between the student’s academic attainments and performance and the symbolic mark, letter or figure. Those learners whose achievements are poorer have an opportunity to receive higher grades through random selection method, whereas more successful and hard-working students might fail in terms of grade. Consequently, one can sum up that the new policy actually measures the person’s luck, as the grade does not depend upon their efforts, skills or abilities. Furthermore, given the definition of education, it is possible to assume that the new grading policy contradicts to the purpose of college or university studies. This principle of grading does not motivate students to develop the necessary knowledge and skills, as their performance is not appropriately evaluated, i.e. the truth about the value of achievement is distorted. Therefore, students, being aware of the fact that the true information about their attainment will not be provided, are unlikely to work on their academic performance and lose the willingness to succeed. To sum up, a positive appraisal of one’s achievements is amongst the major incentives in the education system. The learners thus are unlikely to become true professionals after this motivator is eliminated with the introduction of the new grading policy. Works cited Educational Policies Committee.

Limitations of Captive Breeding

biota 320 Dr. Nissen 08 November 2012 Limitations of Captive Breeding While the expenditure of intent reproductive memory has grown hugely in the more modern old age there has been a complete want of attention paid to the limitations placed on that endangered species by the clothed bring forthing programs. Limitations such as establishing self-sustaining captive populations, poor success in reintroductions, laid-back costs, vapidnesss, preemption of other recover techniques, infirmity outbreaks and maintaining administrative continuity have every last(predicate) been world-shaking ( Snyder et al. 996). We will review the self-sufficient captive populations, reintroductions, and vapidnesss, these atomic number 18 among the most main(prenominal) limitation factors for the review. Establishing self-sufficient captive populations obtaining tenacious reproduction and survivorship under captive conditions has proven quite difficult with many species. at that place are a variety of reasons as to why there has been misadventure to breed well in immurement, and identifying these factors force out be difficult and are still noncitizen even after many years of experimentation.Because of poor reproduction the self-sustaining captive populations may never be achieved for close to of the endangered species (Snyder et al. 1996). In a recent review of 145 reintroduction programs of captive-bred animals, largely vertebrates, besides 11% of the cases were successfully reintroduced into the wild populations (Beck et al. 1994). The causes of the reintroduction disappointment of the captive bred animals vary from a failure to correct the factors originally causing significant behavioral deficiencies in the released animals, to social behavior.The behavioral issues are typically seen in the animals that deprivation the opportunity to associate with wild individuals in a natural setting during the scathing learning periods. Many of the problems affecti ng captive preservation and reintroduction of endangered species are results of familial and phenotypic changes that occur in immurement as well (Snyder et al. 996) and this directly affects the domestication of the captive-bred animal. The implications of the progressive genetic and phenotypic changes are more serious than recognized for the species in long-term captive breeding. Because of progressive domestication the general expectation that one can preserve endangered species in captivity without significant change over a long period of time should be abandoned (Snyder et al. 1996).
