The Neighbourhood Principle

Has The Neighbourhood Principle failed? â€Å"My neighbour asked me if he could use my lawnmower and I told him of course he could, so long as he didn’t take it out of my garden. †1 This is the concept which most people tend to associate the word ‘neighbour’ with. However, in the court room, the word makes a decisive shift away from this traditional meaning and endeavours to establish to whom a common law duty of care is owed. The law has expanded considerably by the onset of the concept of foreseeable plaintiffs which is almost 80 years in existence in the UK.It is evasive in determining â€Å"whether proximity should now be regarded as a discrete analytical concept around which arguments may be constructed, or merely as a slippery expression reflective of the fairness, justice and reasonableness of imposing a duty of care upon the defendant in the light of the nature of his relationship with the claimant. † 2 This essay sets out to establish whethe r the neighbour principle was successful or if it has fallen short and where, it will present court decisions, statutes and constitutional provisions pertinent to this area of law.In articulating what was meant by â€Å"the neighbour principle†, Lord Atkin famously stated the following proposition: â€Å"The rule that you must love your neighbour becomes in law you must not injure your neighbour; and lawyer’s question, ‘who is my neighbour? ’ receives a restricted reply. You must take reasonable care to avoid acts or omissions 1 2 Eric Morecombe (English comedian, 1926-84) Hartstone, J. , ‘Confusion, contradiction and chaos within the House of Lords post Caparo v. Dickman’, (2008) 16 Tort L Rev 8 which you can reasonably foresee would be liable to injure your neighbour?The answer seems to be – persons who are so closely and directly affected by my act that I ought reasonably to have them in contemplation as being so affected when I am directing my mind to the acts or omissions which are called in question. †3 His definition was to become the foundation stone of later cases involving negligence and was, in due course, accepted as â€Å"the first definitive test of when a duty of care was owed. †4 Atkin’s statement has given rise to much discussion. At first, some displayed uneasiness at the very wide and flexible terms in which it was propounded 56.It is important to remark that this neighbour principle formed part of the ratio decidendi of Atkin’s judgment but that it cannot be said that it is the ratio decidendi of his decision. â€Å"For although both Lord Thankerton and Lord Macmillan contemplated the addition of new duties to the law of negligence, neither of them attempted to formulate the principle or principles upon which this might be done. Nor is the generalising approach of the neighbour principle appropriate to the criminal law, where precision and certainty are all-importan t. †7 As a consequence of the Donaghue v.Stevenson [1932] case in the UK, the people were given a potential remedy to take against the providers of consumer products even where no privity contract had been in existence between the 3 4 Ibid at 580 Connolly, U. , Tort Law, (Second Audition, Thomson Reuters (Professional) Ireland Limited, Dublin, 2009) at 16 5 Smith v. Howden’s Ltd [1953] N. I. 137 per Lord MacDermott C. J. 6 London Graving Dock Co. Ltd. v. Horton [1951] A. C. 736 7 Heuston, R. F. V. , ‘Salmond on the Law of Torts’, 17th edition, (Sweet & Maxwell, London, 1977) at 198 complainant and the individual or company tortfeasors.If the proviso for ascertaining that a duty of care was met, then such individuals could bring negligence claims in any situation. The dictum was accepted into Irish law in Kirby v. Burke [1944]. 8 The decision in this case â€Å"stands on the boundaries of actionable negligence,†9 and does not contend nor purport to gi ve guidance on the obligations arising from already distinguished duties, or in fact, recognisable relationships – e. g. that of occupier and visitor. 10 Sometimes the particular duty can subsist contemporaneously with the Atkinian duty,11 but sometimes it displaces it. 2 Duties may be divided into those owed to someone else i. e. â€Å"if it was imposed for the benefit of that someone else;†13 and duties owed to no one in particular i. e. if it was not imposed for the benefit of a particular individual but was imposed for the benefit of the community as a whole or for the benefit of some section of the community. †14 In an ever conscious society, there was much need for the modernisation of the law with regard to the wider duties and especially the neighbourhood principle. The Anns v.Merton15 case brought about the ‘two-stage test’ in order to ascertain 8 9 Kirby v. Burke [1944] I. R. 207 Smith v. Howdens Ltd. [1953] N. I. 131, 137, per Lord MacDerm ott C.

C. 728 the existence of a duty of care in negligence.Lord Wilberforce initiated the requirement of: I. II. â€Å"A sufficient relationship of proximity based upon foreseeability†16 And secondly, the deliverance of reasons as to why a duty of care should not exist. In 1990, concerns arose with regard to the duty of care. 17 â€Å"Lord Bridge and Oliver in Caparo sought to remove any temptation on the part of the practitioners to view proximity as a discrete legal concept capable of precise application to the resolution of legal disputes. Instead, encouragement was given to view proximity in descriptive terms rather than as a definitive concept. 18 Th is time a three-stage test was introduced to establish a duty of care I. II. III. Foreseeability of damage was required, A relationship characterised by neighbourhood19 And that it would be fair, just and reasonable to impose a duty which would benefit the other party. â€Å"The Caparo tripartite approach made no reference to the concept of policy. Instead, Lord Bridge spoke only in terms of a duty of care being imposed where the 16 17 18 Ibid at 741 Caparo Industries Plc v. Dickman [1990] 2 A.

Dickman’ (2008) 16 Tort L Rev 8Lawbook Co. at 13 8Lawbook Co. at 13 19 court considered that it would be fair, just and reasonable to do so. †20 It is also interesting to note that a two-part test is now in place in certain jurisdictions, e. g. New Zealand, for novel fact circumstances where the finding of a duty now has to be balanced against applicable policy mat ters. 21 The two-step test established in Donaghue22 and later developed in Anns23 was that accepted by the Irish courts until 2002 until the decision of Glencar Exploration Plc v.Mayo County Council [2002]. 24 This case marked the adaptation of a two-step test which gave precedence to the â€Å"incrementalist approach†25 that was being applied in the English courts at the time. Implications of the decision in this case made by the Supreme Court became blatant in the case of Fletcher v. Commissioners of Public Works. 26 â€Å"A plaintiff who suffered reasonably foreseeable psychiatric injury, which had resulted from the defendant’s negligence towards him as his employer, was denied the damages awarded to him by the Supreme Court on ‘policy’ grounds. 27 This new approach is much more sympathetic. Since 2005, proximity has once again come to the fore with regards to decisions made by the House, some of their Lordships have adopted it as a â€Å"central ana lytical tool for disposing of appeals. †28 Thus, the notion that this principle of 20 21 22 23 24 25 26 27 28 Ibid at 13 Scott Group Ltd. v.

R. 465 Byrne & Binchy, Annual Review of Tort Law, (2003) at 526 Op cit 26 at 13 proximity could â€Å"have been elevated to the dignity of being a concept in its own right†29 originated. It is subsequently unclear now as to whether it should be regarded as â€Å"a discrete analytical concept around which arguments may be constructed, or merely as a slippery expression reflective of the fairness, justice and reasonableness of imposing a duty of care upon the defendant in the light of the nature of his relationship with the claimant. 30 To bring to a close, the term ‘ neighbour’ and proximity clearly have a much wider interpretation – physical proximity, causal proximity or indeed the denotation of a legal relationship. Furthermore, if this test is satisfied, it is then up to the court to decide whether any policy reasons (or otherwise) exist so as not to acknowledge a duty of care in that particular case. The elusiveness of how this dictum is interpreted may never be resolved. It is the application of policy to novel situations of what is fair, just and reasonable that has instigated the advancement of the neighbour principle.In other fields of law, the broader legal concepts of reasonableness and unconscionability are applied every day. The courts are in a state of uncertainty with regard to the dictum. It is evident that the law has had to expand considerably. So perhaps, in the future, the test of fair, just and reasonable as displayed in the Glencar31 case will be triumphant due to its conversion of the practical, everyday test for negligence into the legal test. Despite having its flaws, it still makes the law comprehensible to all. 29 30 31 Ibid at 13 Ibid at 13 Op cit 34

Aspects of Meaning

Jubayr zakariyya Aspects of meaning assignment 1 The experiment that has been conducted, and written about in the paper ‘The representation of polysemous words', by Devorah Klein and Gregory Murphy, endeavours to uncover the degrees to which different senses of polysemous words use the same or diverse kind of representations. Whilst homonyms from a linguistic perspective, are groups of words that share the same orthographical and phonological characteristics, yet do not share the same semantic meaning.There are a number of theoretical perspectives pertaining to the root cause of how two separate word meanings are able to converge on the same phonological representation, or how a single word is able to separate into diverse and separate semantic meanings. But the term ‘polysemy' refers to something that is intrinsically more complex, and as Klein and Murphy have noted in their paper, more problematical in terms of defining its root source and in which ways are the senses r elated and represented.What Klein and Murphy mean by this, and have studied in this paper, is the process in which words semantically relate to one another, through a process of extension. Yet unlike homonyms, polysemous words do not have lexically separate meanings, which leads to the questions of whether polysemous words have a single represented sense that can be accounted for every use of a word, how can they be linked in memory, and how are they co-ordinated in processing. Klein and Murphy aim to ‘provide data that will constrain accounts of the representation and processing of polysemy'(Klein and Murphy (2001)).The first experiment that was conducted entailed the use of memory performance in order to measure the representation of polysemous senses. it was particularly looking at whether people were more familiar with a same sense or a different sense than the original presentation given. the results showed that same phrase items were the most precisely evaluated, which w as followed by the consistent sense phrases. The inconsistent sense phrases were the most error prone. Klein and Murphy also suggest that words being seen in identical context was the most helpful in getting a correct evaluation.The results here point out that the way in which a polysemous word is processed initially affects later memory access. After conducting a number of detailed experiments, Klein and Murphy conclude that polysemous senses are semantically related, yet they are not extremely similar, which consequently results in ‘same-sense facilitation' and ‘cross sense inhibition' (Klein and Murphy (2001)). If a polysemous word does not contain a core meaning, it is no longer a substantial semantic component thatis common to all senses in a given word. word count: 429

Studying Abroad Helps Improve Language Skills

Studying abroad is always a memorable experience, especially if you choose to live in a country where you don’t speak the language. It will be the best way to learn foreign language. In fact, most students choose to study abroad in the first place for the opportunity to gain proficiency in a foreign language. Despite the difficulties, it’s important to really focus on improving your language skills while you have the chance to live in a country with native speakers. If you want to get the hang of a foreign language while studying abroad, don’t hesitate to make local friends.Your language skills may not be good enough to speak with them comfortably in the native language, but you will still pick up quite a bit of phrases and vocabulary words from being around young locals that you would not have access to otherwise. And I think wandering around alone will also help you improve your language skills. You will have chance to make friends with strangers, speak to the grocer or waiter, eavesdrop on the bus, and do all the other things that help you improve your basic communication skills. So go out alone, do your own communicating and listening.And don’t forget reading magazines interview. The local papers and magazines sold on every corner will offer a wide array of inexpensive reading material in the language you’re learning. Also, reading interviews, specifically, helps improve communication skills. When studying a language, students are not always given examples of real conversations that involve unique questions and answers. Magazine and newspaper interviews capture nuanced words and phrases that aren’t in the typical textbook. In short, studying abroad is the best way to improve your language skills.

Its very clear from the writings of the Spaniards in New Spain that Essay

Its very clear from the writings of the Spaniards in New Spain that the conversion of the Azetecs Christianity didn't completely - Essay Example They made statues representing their gods. Some of the gods were made from seeds and vegetables joined by blood from human hearts. Cortes reported this in his letter citing â€Å"after they are made they offer them more hearts and anointed their faces with blood† (Andrea and Overfield 463). The sacrifices involved anointing these idols with sacrificial blood. The market place formed an important part of their culture. Cortes, who led the Spanish forces that conquered the Aztecs, reported, â€Å"This city has many squares where trading is done, and markets are held continuously† (Andrea and Overfield 462) Cortes continued to expound on the expanse of the market and the range of merchandise. He indicated that he could not report all of them saying â€Å"but they are so many and so varied† (Andrea and Overfield 463). The Spaniards conquered the Aztecs in 1521, after which they introduced Christianity to the inhabitants of the fallen empire. However, despite the intr oduction of Christianity, their transformation was not complete as they continued with some of their cultural practices. Andrea and Overfield presented an excerpt from the writings of Duran. Duran served as a priest from 1556 until his death in 1588. One of the ways that the priest noted remained unchanged was attendance to the market places. The markets, as previously indicated, formed a chief part of the Aztec culture. The markets were operational throughout, and people were compelled by law to attend the market fairs. Duran observed that the custom of attending markets after a number of days continued among the people. He wrote, â€Å"The markets were so inviting, pleasurable, appealing, and gratifying to these people that great crowds attended, and still attend†¦Ã¢â‚¬  (Andrea and Overfield 405). He further noted that when the market days were on Sundays, no one attended the mass. He noted, â€Å"Occasionally, this falls on Sunday, and no one hears the mass in the area o f the town where the market is held† (Andrea and Overfield 405). This attachment to the market place was so strong that it was placed first before Christianity. Duran presented this in what he thought was the most probable reply from a woman choosing between heaven and the market. He perceived the woman would say, â€Å"Allow me to go to the market first, and then I will go to heaven† (Andrea and Overfield 405). Duran identified three ways through which a person could receive honor in Aztec. These included soldiery, religion and trade. Soldiery was the first and the main way, while trade was the least admired. Nevertheless, it presented a credible way of attaining honor. Traders who traded in expensive wares and acquired wealth received recognition like brave soldiers. Duran reported that â€Å"and so they were considered among the magnates of the land, just as the valorous soldier† (Andrea and Overfield 404). Thus, the market presented one way that was accessibl e to most of the people. Duran noted that this attachment to the market as a way to acquire status did not end with the introduction of Christianity by the Spaniards. He noted of how merchants saved up to twenty years and prepared expensive parties, which consumed all their savings. Duran added, â€Å"This could not be wrong except that for their celebration they await the day on which the god was honored† (Andrea and Overfield 405). This indicated the unchanged connection between trade and honor in the people’s life. Additionally, attending markets presented a form of

Wireless Technologies - Research Paper Example This paper aims to discuss wireless technologies with respect to its initial development, current status and the future prospects. Introduction to Wireless Technologies Few decades back the wireless technology was an unreal phenomenon for a common man but today millions of people communicate with each other through the wireless networks. This clearly represents that the wireless technology has undergone tremendous success in the last few years which has made it not only publically available rather it has also advanced the computer communication systems. In broader terms, wireless technology has its roots in the radio waves which travel through the space with the help of electronic signals (Mathias, 2004). Comer in his book related to the computer networking argues that no single model can actually explain the real theory behind the development of wireless technology (Comer, 2008). However, this can only be understood by rigorously investigating the initial development of electricity, electromagnetism and the radio waves. Although the wireless technology is significantly complex in nature but it has brought flexibility, value and ease in terms of communication and business networking. It functions on the basis of electromagnetic energy such as the radio waves, laser, infrared etc. The most common examples of wireless technology are the T.V. remote controller and the cellular devices. In internet or Local Area Networks more complex forms of data transferring systems are used which help in fast communication between two or more computers. This signifies that the fundamental purpose of wireless technologies is to provide safe and reliable platform for data transference. Hence the modern scientists are now striving to increase the strength of wireless internet (Mathias, 2004). Wireless Technologies of the Past How and why Wireless Technology was first developed? Research indicates that the wireless technology was actually initiated some 200 years ago when Benjamin F ranklin conducted his renowned kite experiment. The radios, mobile phones and the internet that we use today are a result of continuous improvement and experiments over the time. Wireless Technology does not evolved through single experiment rather it was followed by electromagnetic theory, highly significant inventions and the development of radio waves (Mathias, 2004). In 1747, Franklin actually proposed an electricity model which gave way to the development of fast, highly reliable and cheap wireless system. Franklin was primarily working on the electricity generation however, during his experiments he realized and later concluded that electricity can actually move through the air medium. In 1819, A Danish physicist identified the astonishing relationship between magnetic and electric field. He observed that the needle of a compass was moving when placed into the electric field. This phenomenon was later termed as electromagnetism. Michael Faraday, in 1831 built the very first ge nerator which was operated through direct current. Although his experiment was not beneficial in the way of wireless technology but it did provide a clear way to the future scientists to work upon (Mathias, 2004). Later James Clerk Maxwell gave the theories on electromagnetic waves travelling through the space. These actually laid the foundation of wireless technology. These equations were then used by Heinrich Hertz who invented the oscillator in 1887 which helped in the creation of radio waves. Thereafter the FM radio, electronic tube and the digital decoding systems were developed. These were then linked with the wireless

Monoclonal antibodies Essay Example | Topics and Well Written Essays - 2000 words

Monoclonal antibodies - Essay Example The fusion of myeloma cells together with mammalian spleen cells results to a hybrid cells that produces a high amount of the monoclonal antibodies. Out of this experiment, two types of cells are produced. One has the potential to grow continuously while the other has the ability to produce large amounts of monoclonal antibodies. Monoclonal antibodies are works better than convectional drugs since the antibody specifically targets the antigen and does not have negative health effects like the conventional drugs, which causes side effects after being used (Hsu, 1990, 34). If the amount of monoclonal antibodies becomes excess in the blood, it means that there is the presence of abnormal protein in the blood.   Screening of blood helps to identify these proteins through a process called protein electrophoresis. The plasma cells in the bone marrow are the main source of the production of monoclonal antibody abnormally.Monoclonal antibodies production  Hybridoma produces the monoclona l antibodies. Hybridoma cells can be made through fusing two cells so that the characteristics of two cells can be combined into one cell. One of the two cells should be myeloma, which is the tumor cell while the other should be the antibody-producing cell. The hybridoma produced in the laboratory has the ability to replicate faster than the normal cells that produces antibodies (Newcombe, 2007, 23). One common way in which the immune system of the humans fights diseases or presence.... pecifically targets the antigen and does not have negative health effects like the conventional drugs, which causes side effects after being used (Hsu, 1990, 34).

The hybridoma produced in the laboratory has the ability to replicate faster than the normal cells that produces antibodies (Newcombe, 2007, 23). On the other hand , the tumor cells have potential to grow endlessly and at a higher rate than the normal cells. A specific monoclonal antibody that is originally produced by the B-lymphocyte is manufactured by the hybridoma cells. One common way in which the immune system of the humans fights diseases or presence of an antigen is through the production of large amounts of antibodies (Birch, Lennox, 2000, 30). These antibodies keep circulating throughout the body until they come across an antigen, which they will attach themselves on. As soon as they attach themselves, they alert the rest of the immune system to produce many of the antibodies to fight the specific antigen found. Monoclonal antibody can be produced in the laboratory and its effectiveness carries a higher percentage since it is designed for a

How do you define success Essay Example | Topics and Well Written Essays - 250 words - 1

How do you define success - Essay Example Irrespective of the ethical value of goals, achievement is referred to as success, but only in the individual’s own viewpoint. Hence, success can be defined as attainment of objectives. However, this definition pertains only to an individual’s personal viewpoint about the results of his/her efforts. People have their own standards of rendering an individual’s attainment of his/her objectives successful. The world regards ethics and morality. Therefore, people whose achievements induce positive changes in the world in any way are considered successful by people. On the contrary, people deem an individual’s efforts as failure if the individual attains his/her goals but they cause negative changes in the world. â€Å"Hitler succeeded in storming across Europe, Napoleon succeeded too, Al Capone, Sam Giancanna, John Gotti, and others succeeded in becoming crime king pins. Stalin succeeded in murdering millions of his own people† (â€Å"Affirmations for Radical Success†). Not all of these people are considered successful

STRATEGIC SUPPLY CHAIN AND LOGISTICS MANAGEMENT Essay

STRATEGIC SUPPLY CHAIN AND LOGISTICS MANAGEMENT - Essay Example p.141.). An organization with strong supply chain integration can easily achieve competitive advantage resulting in efficient performance of the operational activities. According to Dolgui and Proth, â€Å"a supply chain is a global network of organizations that cooperate to improve the flaws of material and information between suppliers and customers at the lowest cost with the highest speed† (Dolgui and Proth, (2010), p.113). The primary objective of supply chain management is to provide high satisfaction to the customer group through effective operational processes. The task of managing efficient supply chain for meeting its objectives is known as supply chain management (SCM). Monezka and colleagues defined SCM as a concept â€Å"whose primary objective is to integrate and manage the sourcing, flow, and control of materials using a total system perspective across multiple functions and multiple tiers of suppliers† (Mentzer, 2001, p.8). Retail market is a service industry where finished goods are sold to the final consumers. The core operational activity of a retailer is to provide service to customers by selling products manufactured by different organizations. Therefore, in retailing business, the activities related to supply chain are of paramount importance. Hence, managing supply chain in retail business is more challenging as it determines the level of consumer satisfaction. The primary objective of this paper is to analyze the supply chain related issues of the supermarket and to develop a relevant and valid supply chain management for retailing business. The SWOT analysis of supermarket will help to realize its current position for framing its supply chain model. In order to support the proposal, two relevant research papers related to supply chain will be explained. Finally, the paper will be concluded by offering valid recommendations on the basis of the analyses and

The differences between primary school in England and Saudi Arabia Essay

The differences between primary school in England and Saudi Arabia - Essay Example The extent to which the models and theories of education build experience for children has elicited interests among the researchers. The systems of education in Saudi Arabia and England offer different levels of experience because educators in both countries adopt different models of educational transmission. Experience constitutes the aspects of intellect and consciousness, which children acquire when they undergo learning processes. They constitute a combination of thought processes, emotion, will, perception and imagination (Rowe, Herrera, Hughes, & Cawley, 2012). The models used by teachers to transmit knowledge to primary school children largely determine the extent to which learners acquire desirable experiences in education. Superior experience refers to the ability of one education system having a higher potential to enhance children’s learning than the other system. Models of educating children are characterised by diverse features and are applicable in different contexts. Factors that lead to superior experience include the educations system of a country, the content of the curriculum, and learners’ autonomy; further details concerning these factors are discussed in the analysis part. Models that promote superior experience enhance development of children across all spectrum of life including economic, social, and political aspects (Bloxham & Boyd, 2012). Superior experience is achieved through educators and curriculum developers focusing on all dimensions of Bloom’s taxonomic units when developing and executing the curriculum. Bloom’s taxonomy consists of cognitive domain, affective domain and psychomotor domain. Additionally, superior experience results from having courses developed by educators who understand the reality of primary classrooms (Schneider, 2013). Experienced educators have the potential for reviewing and updating courses regularly to ensure activities,

Successful person interview Essay Example | Topics and Well Written Essays - 1000 words

Successful person interview - Essay Example He goes on to add that there has been a general misconception concerning work, that placing family in a place of importance in one’s life hinders their growth in terms of career. He states that when family is in the right place in one’s life, they are happy and content thereby proving a good working environment for them and support whenever it is necessary. This view, is in live with one of Carvey’s 7 habits of highly effective people that states that they must be able to put first things first. He further explains the concept by looking at his life, stating that even before he became a diplomat, he was already a successful man. He explains how his nomination took place, stating that he did not apply for the job, rather his qualifications and diligence put him in a position of recognition and thereby the appointment, what he called the elevation. When asked what he did to be successful, he failed to answer that question, saying that it purported the wrong idea that he was working towards success, rather, he corrected it, to why he was successful. To this, he answered that he was successful because he had applied himself to wisdom and diligence in his work, choosing integrity over corruption and excelling in the little things he did thus achieving success way before anyone thought him to be successful. He further added that he chose to take the high road that involved tough times and hard days of work, persistence in doing what was right and above all prayer. Further asked whether he was a religious man, he said that he was not, rather he was a Christian. Interested in what would cause a man to make such bold statements, I asked him whether he truly believed that his Christianity had anything to do with his success. To this, he answered that it did not have anything with it; rather, it had everything to do with it. He added that even if he knew that that downplayed his role in his success, it did not matter because, it was the truth. He

International finanicial manager (slp 5 bus) - Essay Example transnational corporation acquire, organize and manage those assets is of critical importance, not only to the success of those corporations, but also to the development and industrial restructuring of nation states. The task of international financial manager is to make the best possible tactical decision that the market has to offer on liabilities, within the strategic funding constraints set by currency denomination, maturity, and capital structure Almost every firm, government agency, and other type of organizations have one or more financial managers. Financial managers oversee the preparation of financial reports, direct investment activities, and implement cash management strategies. Managers also develop strategies and implement the long-term goals of their organization. The role of the financial manager, particularly in business, is changing in response to technological advances that have significantly reduced the amount of time it takes to produce financial reports. Financial managers now perform more data analysis and use it to offer senior managers ideas on how to maximize profits. They often work on teams, acting as business advisors to top management. Financial managers need to keep abreast of the latest computer technology to increase the efficiency of their firm’s financial operations. Controllers direct the preparation of financial reports, such as income statements, balance sheets, and analyses of future earnings or expenses. Controllers also are in charge of preparing special reports required by regulatory authorities. Often, controllers oversee the accounting, audit, and budget departments. Treasurers and finance officers direct the organization’s budgets to meet its financial goals. They oversee the investment of funds, manage associated risks, supervise cash management activities, execute capital-raising strategies to support a firm’s expansion, and deal with mergers and acquisitions. Cash managers monitor and control the flow of

EGT1 †Economics and Global Business Applications Essay Example for Free

EGT1 – Economics and Global Business Applications Essay Elasticity of demand is a measure of responsiveness to a price change of a good or service. When demand is elastic, the percentage of a price change of a product will result in a larger percentage of quantity demanded (McConnell, p 77). It basically means reducing the price of a good service will result in a greater quantity demanded and an increase in revenue for the seller. When demand is inelastic, a change in price will result in a reduction of quantity demanded, which will then lead to a revenue decrease (McConnell, p 77). To demonstrate elastic and inelastic demand results, Company A sells 100 pens at $1.00 a piece each day, making their revenue $100.00. Company A then decides to sell their pens at $.50, which results in a total of 250 pens being sold. The total revenue from the price drop is $125, resulting in an additional $25.00; therefore the demand in this scenario is elastic. If selling the pens at the decreased price of $.50 would result in more pens being sold, but less total revenue, the demand is said to inelastic. According to McConnell, when demand in unit elastic, the percentage change in price and the resulting percentage changes in demand are the same. The change in price will not increase or decrease revenue. Cross price elasticity measures the response of demand to a change in price of another substitute or complimentary good (McConnell, p. 87). Substitute goods are goods that can be purchased in place of another good. Examples of substitute goods are soda (buying Coke vs. Pepsi), computers, and potato chips. A positive cross elasticity of demand means the increase of price in one good, for example Coca-Cola, will increase the demand of a substitute good, for example Pepsi. As the price for Coke increases, consumers are more likely to purchase Pepsi at a lower price, thereby increasing its demand. Complementary goods are items that are typically purchased in conjunction within one another. Examples are ringed binders and notebook paper, pencils and erasers, and potato chips and dip. A negative cross elasticity of demand in complementary goods means that the increase in price of one good, an example being potato chips, will decrease the demand for the complementary product that goes with it, the dip. Income elasticity measures the responsiveness of consumers to changes in their incomes (McConnell, p 88). Demand for normal goods tends to increase as consumers’ incomes increase and conversely, demand for inferior goods tends to decrease as consumers’ income increases. Demand is elastic where there is a large availability of substitutes. The reason for this as the price of a good increases, if there is a large amount of substitutes for this particular good, the consumer will choose the substitute. As discussed earlier, soda is an excellent example of this elasticity. Airline tickets are another example. As one airline raises its cost of a ticket or to even pay for a bag to be checked, a consumer will more likely choose a cheaper ticket or an airline that doesn’t charge for baggage over the original. If there is no (or a very limited) amount of substitutes for a good, elasticity is said to be negative. A price change in medication will not likely change the behavior of a consumer relative to demand since there isn’t a substitute to taking the medication. Household utilities are another example of a limited amount of substitutes. In discussing the proportion if one’s income devoted to a good concept, the household budget comes into play. In a given month, households pay for many different good and services. A change in price may or may not affect the households demand for those goods and services. Often, it is dependant on how much of the household budget is devoted to that good or service. Mobile phone service is an excellent example of a service that will most likely have a large amount of a household budget dedicated to it. A change in price in the cell phone service will most likely result in that family making a decision to change to a cheaper service, since that will have a large impact on their budget. On the other hand, that same household may purchase light bulbs each month. The amount of money dedicated to the purchase of light bulbs is so small, that a price increase will not likely affect the budget, therefore the family will not likely make a decision to change to a cheaper bulb. The concept of time when discussing demand is important. When a consumer has a large amount of time to decide on the purchase of a good or service, the elasticity is positive. Conversely, if there is little time, the elasticity is said to be negative. According to McConnell, and excellent example of this is gasoline for automobiles. Gasoline prices change daily and more often than not, prices rise. A family, who owns a car and is dependent on that car for work, etc, will not likely stop buying gas in the sort-term, because it is crucial to their everyday living. However, that family over a long period of time may decide to find alternate means of travel, decreasing their demand for gas. Using the graphs for elasticity of demand and total revenue, areas of elasticity, inelasticity and unit elasticity have been identified. Demand is elastic between the prices of $80.00 and $50.00, meaning the demand increases as the price decreases, resulting in an increase of total revenue. Between the prices of $50.00 and $40.00, the demand in unit elastic, meaning the percentage of drop in price resulted in the same percentage of increase in demand. Revenue remained unchanged in this price range. Between the prices of $40.00 and $0, the demand is inelastic, meaning the price drop has resulted in an increase in demand, but not enough to over come the decrease. Total revenue has been negatively impacted.

Silver-graphene Oxide Composite for Optical Sensor

Silver-graphene Oxide Composite for Optical Sensor KHOSRO ZANGENEH KAMALI ORIGINAL LITERARY WORK DECLARATION FORM ABSTRACT In this work, a [emailprotected] oxide ([emailprotected]) nanocomposite-based optical sensor was developed for the detection of biomolecules such as dopamine (DA), ascorbic acid (AA), and uric acid (UA). An aqueous solution of [emailprotected] was prepared using a simple chemical reduction method, and it showed a characteristic surface plasmon resonance (SPR) band at 402 nm. The SPR features of the [emailprotected] nanocomposite were used for the detection of DA, AA, and UA. The SPR intensity-based limits of detection (LoDs) of DA, AA, and UA were 49 nM, 634 nM, and 927 nM, respectively. The SPR band position-based LoDs of DA, AA, and UA were 30 nM, 1.64 à ¯Ã‚ Ã‚ ­M, and 2.15 à ¯Ã‚ Ã‚ ­M, respectively. The present optical sensor was more sensitive to DA than to UA and AA. The interactions of the biomolecules with [emailprotected] were studied based on the density functional theory (DFT), and it was found that DA had more interaction than AA and UA. This novel [emailprotected] nan ocomposite is simple to prepare and showed excellent stability and sensitivity toward the detection of biomolecules. The similar material is used for colorimetric detection of Mercury(II) ions (Hg(II)) that is able to show existence of 100  µM Hg(II) ions in solution by naked eyes. The development of this optical sensor for Hg(II) using silver nanoparticles (Ag NPs) is based on the decrement in the localized surface plasmon resonance (LSPR) absorption of the Ag NPs and the formation of silver-mercury (AgHg) amalgam. It is observed that increasing Hg(II) ions concentration in the solution results in the decrease of LSPR intensity and decolouration of the solution. The existence of GO prevents the agglomeration of Ag NPs and enhances the stability of the nanocomposite material, enabling this material to be used in industrial and real sample applications.

Hence, they are used in a wide range of applications such as catalysis 1, solar cells 2,3, and optical 4 and electrochemical sensors 5. Ag nanoparticles possess a sharp absorption in the visible region (400–500 nm), depending on the size of the nanoparticles. This absorption feature arises from the surface plasmon resonance (SPR), which is the absorption of light by the nanoparticles because of surface vibrations between atoms 6–8. This SPR feature allows Ag nanoparticles to be used in optical sensors for the detection of toxic metals 9, biomolecules 10, and organic compounds 11. The addition of any analyte to the Ag nanoparticles leads to assembled/aggregated nanoparticles. This influences the SPR absorption band and is extensively used to follow the molecular recognition processes. Dopamine (DA) is an important catecholamine that belongs to the family of excitatory chemical neurotransmitters. It plays an essential role in the functioning of the drug addiction, cardiovascular, renal, central nervous, and hormonal systems, and in Parkinson’s disease 12. Thus, it is very important to develop a simple sensor for the detection of a sub-micro-molar concentration of DA. In recent years, the detection of biomolecules such as uric acid (UA) and ascorbic acid (AA) in human fluids such as urine and serum has gained considerable attention 13. A deficiency or excess amount of UA in the body causes several diseases, including Lesch/Nyhan syndrome, hyperuricaemia, and gout 14. Cardiovascular disease and kidney damage result from an elevated UA concentration in serum 15. Analytical methods such as high-performance liquid chromatography (HPLC) 16, spectrofluorimetry 17, spectrophotometry 18, mass spectrometry 19, and electrochemical sensors 20 have been reported for the detection of these neurotransmitter molecules. However, the existing detection methods have several limitations such as the need for expensive equipment, well-trained operators, and tedious sampling and time-consuming procedures. Alternatively, an optical sensor platform is more attractive for sensing a wide range of analytes. It is cost effective, portable, has a rapid response, and can provide real-time analyses. Recently, Ramaraj and his coworker reported a silicate-Ag nanoparticle-based optical sensor for the detection of DA, UA, and AA with LODs of 5, 5, and 1 nM, respectively 9 (Figure 1). Most commonly, Ag nanoparticles are synthesized using various chemical and physical methods, which are not eco-friendly and suffer from problems that include the poor reproducibility and stability of the Ag nanoparticles due to colloidal aggregation 21. In order to overcome such limitations, considerable efforts have been made to prepare Ag nanoparticles on polymer 22, silicate sol-gel 11, and graphene nanosheets 23. Among these, Ag-graphene has a large surface area and strong van der Waals force between the graphene and Ag nanoparticles, which significantly reduces nanoparticle aggregation. In addition, the high interfacial interactions ensure the stability of the Ag nanoparticles 24. In this study, graphene oxide-supported Ag nanoparticles were prepared using a simple chemical reduction method and used in an optical sensor for the detection of biomolecules such as DA, AA, and UA (Figure 2). The present synthetic method for the for preparation of [emailprotected] nanocomposite has a dvantages over other methods 11, 21-24 such as, long term stability, high homogeneity, rapid and ease of preparation and avoids any surfactant, stabilizers. Silver nanoparticles (Ag NPs) attracted much attention due to its biocompatibility, high catalytic activity, anti-bacterial activity, electronic and optical properties 25–28. The Ag NPs possess a principal absorption band in the region of 400 nm due to the localized surface plasmon resonance (LSPR)29,30. This SPR feature of Ag NPs is aroused due to the collective oscillation of electrons on the surface of the Ag NPs that are excited by incident electromagnetic waves 31. The SPR band position and intensity mainly depend on the size, shape and refractive index 32. This SPR band of Ag NPs is more sensitive to the surrounding environment and it significantly influences the band position and intensity. Based on the changes in the LSPR band position and intensity, an optical sensor platform with Ag NPs was developed to detect the wide range of analytes, including biomolecules 33, nitroaromatics 34, phenolic compounds 35, and heavy metal ions 36. Among the investigated analytes, heavy metal ions especially Hg(II) ions are more often monitored with Ag NPs through the optical sensing method owing to its high toxicity and solubility in water37. Mercuric (Hg(II)) ions are mainly released into the atmosphere from solid waste incineration, power plants, and bumping fossil fuels38 that pollute water, soil and air 39,40. The existence of Hg(II) ions in water causes serious damage to the brain, nervous system, kidneys and endocrine system of living organisms41. Developing a system for detecting Hg(II) with high sensitivity and selectivity against other common metal ions dissolved in water is a challenge in recent years 42–47. From an environmental point of view the development of an inexpensive, simple, selective and sensitive method of detection of Hg(II) becomes highly important. There are many types of sensors invented to detect Hg(II) in the environment. Some studies reported the detection of Hg(II) ions using electrochemical methods 48,49. Although they achieved a very high limit of detection (LoD), they need to use expensive apparatus and complicated setup. For the electrochemical testing of Hg(II) sample, the fabrication of an electrode is necessary, and that is a very tedious process. In addition, the detection of Hg(II) using fluorescence spectrometry has been widely investigated 50,51. Although this method is simple and is able to detect trace amounts of Hg(II) ions in solution, it requires expensive equipment to work. In this respect, colorimetric sensors are cheaper and do not require tedious preparation methods, colorimetric sensors have the advantage that the existence of Hg(II) is easily discernible to the naked eye without being affected by other possible dissolved ions 52–59. Recently, Hg(II) ion sensing was reported with noble metals su ch as Au and Ag by utilizing the size/interparticle distance-dependent optical properties and high extinction coefficients 60–62. The interaction between surfactants and metal NPs results in changes to the refractive index of these NPs and the LSPR band 32,33. They also may electrostatically repel the analyte, preventing it from interacting with the metal NPs and reduces the sensitivity of the sensor. In this study, the Ag NPs was prepared by using a simple chemical reduction agent and stabilized on graphene oxide (GO) sheets. Subsequently, the [emailprotected] nanocomposite was used to develop a colorimetric sensor for the detection of Hg(II) with the naked eye and an optical sensor also developed based on the LSPR changes upon the addition of various Hg(II) concentrations. This significant change in the LSPR of the Ag NPs is due to change in the morphology through the formation of AgHg amalgam. Selectivity in the detection of Hg(II) in the presence of various environmentall y relevant metal ions was also studied. CHAPTER 2: LITRETURE REVIEW 2.1. Plasmonic band of metal Nanoparticles Most probably gold nanoparticles (NPs) synthesized in the 5th or 4th century BC in China and Egypt regions 63. From that time, gold NPs have been used in both medicine and aesthetic aspects. As the result of the interesting optical properties of gold NPs, they were used for changing color of glass 64, pottery and ceramics 65. Faraday got interested about the optical properties of gold NPs and reported about the range of colors of gold nanoparticles colloidal solutions from ruby red to amethyst in 1857. Then he studied the factors influencing the color of gold NPs solutions and concluded that ‘‘the mere variation in the size of particles gave rise to a variety of resultant colors’’. Other than their optical properties, many applications of metal nanoparticles have been found in biochemistry, catalysis and sensors. For instance, one of the anti-odour commercialized devices in Japan is using the technology of immobilizing gold nanoparticles in oxide matrixes as active oxidation catalysts 66. In defenitions, nanoparticles are particles composed of number of atoms, ranging from 3 to 107 67. Nanoparticles feature properties are different from atoms or bulk material due to their size. The metallic nanoparticles larger than 2 nm possess a strong and broad absorption band in the UV-visible spectrum that is called surface plasmon resonance (SPR) band. This absorbance has discovered by Gustav Mie and known as Mie resonance 67. For smaller nanoparticles, quantum effects become more prominent and LSPR disappears. All metal nanoparticles possess the mensioned optical property, but the series of Au, Ag and Cu have very intense LSPRs. Other than that, their easy synthesis methods and their robustness to environmental conditions made silver and gold NPs to widely be used in this field. The LSPR features such as position, shape and intensity are strongly depends on various factors, to mention: the changes in the interparticle distance of the NPs and , a nd the changes in the refractive index of the local surrounding environment 68. There are indeed other types of plasmonic signals, such as the surface plasmon resonance band produced by planar metallic films, in reflection or transmission, some of them being called plasmon polaritons. Though the resulting physics is extremely exciting and the recent discoveries numerous, it is out of the scope of present thesis and they will not discuss further. In recent years, many theories were adopted by both physicists and chemists in order to give a clear description of the SPR band and on the main factors impacting its position, broadness and intensity. Many works has done to overview the existing plasmon band theories 67, and explain the SPR band by Mie and effective medium theory 69. There are some researches to explain optical propertiese of NPs with arbitrary shape by Maxwell equation theory 6. The phenomenon on absorbance of certain wavelength of light observed in transmission of light through metal nanoparticles in solid or solution phase, is called localized surface plasmon resonance band (LSPR).Nanoparticles intract with incident light in certain frequency that result global scattering of it. This observation can be explained by the collective resonance of the conduction electrons of the nanoparticle, due to interaction of electrons in nanoparticles with light. The evaluation of all parameters of material, specially its dielectric constant is necessary for understanding and study this phenomena. Usually, dielectric constant of nanoparticles count same as its bulk form and confinement effects and defects induced by edges or impurities will be neglected. For this aim a study on electrostatics in bulk metal by using Maxwell equations is necessary. In formulating the dielectric constant with known parameters, the Drude model, which describes the motion of free electrons in a metal can be applied. Then the question of the nanoparticles will be addressed: the conditions for conducting electrons resonance will be determined by several means. The determination of the frequency of the absorption maximum (denoted , the frequency of the Mie resonance), the height of this maximum and the width of the peak will be the ultimate goal of the calculations. The different geometrical confinement effect of free electrons on each material caused the electronic motion for nanoparticles vary material by material. Indeed, here the nanoparticles can be seen as a cationic network in which a cloud of conducting electrons (or free electrons) moves and oscillates. Nanoparticles dimensions are very small compared to the wavelength of the UV-visible light for which the phenomenon is observed and also comparable to the mean free path of electrons. The surface plasmon band is known to the resonance of the electronic cloud with the incident wave and the mechanics of this phenomeno n can be evaluated. In the case of nanoparticles, the conditions that electron cloud can resonate needs to be calculated. For this aim, The dielectric constant of metal nanoparticles assumed to be the same as the bulk material. Some postulates then become incorrect, but in calculation we have to keep them as an approximation. For instance, the electron density in small particles (r = 0) is not uniform and the charge will accumulate in particle edges and surface. Other than that, since the size of nanoparticles is very small comparing to the wavelength of incident light, we can consider that all electrons in the nanoparticle face with the same field at the given time and the electric field is independent of position 67. This hypothesis is known as the quasi-static approximation. When the electric field incidents to the particle, it result the displacement of the electron cloud that leads to the creation of surface charges. The positive charge would be where the cloud is lacking and the negative charge would be where it is concentrated (Fig. 1). 67 The therm â€Å"surface† is justified by the electron cloud charge mentioned in previous statements. However, we have to kep in mind that all the electrons are moving together (collectively) under the influence of electromagnetic field. This collective oscillation leads to plasmon polaritons, 64 that is different with the free plasmon in the bulk metal.67 The term â€Å"plasmon† was given to the SPR phenomenon by Shopper, due to the bounded gaseous plasmon oscillations.67 The dipolar charge repartition imposes a new force on the electron cloud. The electrons undergo a restoring force which conflicts with the external electric field. Figure.‎0.1. Schematic description of electronic cloud displacements in nanoparticles under the effect of a electromagnetic wave. 2.2. Graphene Oxide Recently, chemically modified graphene (CMG) has been studied in the context of many applications, energy-related materials, such as polymer composites, ‘paper’-like materials, field-effect transistors (FET), sensors, and biomedical applications, due to its excellent electrical, mechanical, and thermal properties. 70–72 Chemical modification of graphene oxide, which is generated from graphite oxide, has been a promising route to achieve mass production of CMG platelets. Graphene oxide contains a range of reactive oxygen functional groups, which renders it a good candidate for use in the aforementioned applications (among others) through chemical functionalizations. Although graphene known a relative novel material of broad interest and potential,1,3 GO has a history that extends back many decades to some of the earliest studies involving the chemistry of graphite.4–6 The first, the British chemist B. C. Brodie was exploring the structure of graphite by investigating the reactivity of f

The Effect Of Cartoon Violence Media Essay

The Effect Of Cartoon Violence Media Essay Research Question: Does the violence depicted in cartoons have a negative influence on young viewers between ages 3-5 in America, and does it promote aggression and/or violent behavior. Introduction: Nowadays it is a common belief that the violence portrayed in cartoons might have a negative impact on the behavior of young children. The main aim of this Essay will be to determine whether cartoon violence has a negative influence on the behavior of young children aged 3-5 in America or whether this assertion is merely a false presumption. If the claim is true, we will be considering any possible effects it may have on the behavioral development of those children in the future. My main scope of research will be consisting of various analyses of popular cartoon shows in the United States, along with various books, articles and online forums containing relevant information in order to aid me in providing a suitable solution to the research question. Many young children in America are believed to be spending an average of up to 30 hours of television a week  [1]  and the majority of their free time watching cartoons on television where they could be exposed to a variety of harmful scenes. Allowing young children to watch high amounts of cartoon violence might result in unwanted consequences and perhaps an undesired change in the behavior of the child. Presumably this is because the majority of cartoons that are displayed on the television contain some form of violent activity which could affect the undeveloped minds of young children in an undesired way, as well as possibly promoting violent behavior. Violence in cartoons can be extremely harmful to children of young ages as they have difficulties distinguishing reality from fantasy because their brain has not yet reached a state of maturity.  [2]  Americans are concerned because preschoolers social and emotional development could be negatively linked with cartoon violenc e and aggressive behavior.  [3]  While on the other hand it is believed by many people, especially by adults, that the violence depicted in cartoons has no serious or dangerous effects on young viewers in America which are worthy of concern.  [4]   This topic is worthy of investigation because the number of children being exposed to cartoon violence is supposedly increasing each day with the average rate currently standing around 1hour of television per day, most of which is made up of cartoons  [5]  . This could potentially result in aggressive and/or violent behavior by the preschoolers towards others in their surroundings. This information is worthy of notice because some of the most popular and most frequently watched cartoons have been featured to contain some of the highest amounts of violent and aggressive activity on television  [6]  which may have undesirable consequences on young viewers if overly exposed to such content. Accordingly this topic should be carefully investigated in order to be capable of preventing, and treating any unwanted outcomes of overexposure to violence in cartoons because investigation towards the effects of cartoon violence may be able to help prevent or minimize the development of vio lent behavior patterns among preschoolers in the United States. Development: Today it commonly known that many young children all around the world, including preschoolers in America, spend most of their day and a majority of their spare time watching the television. In fact recent studies have shown that in America, preschoolers alone were known to be watching an average of up to 30 hours of television a week.  [7]  It has been discovered that an average four year old child in America watches anywhere between 50 and 70 minutes of television a day, consisting mostly of cartoons.  [8]  This information is worthy of careful observation because some of these cartoons have been featured to contain some of the greatest amounts violent and aggressive scenes on television.  [9]  Research has shown that in-between years 1973 and 1993, over 90% of childrens weekend morning programs contained some form of violent activity, with an outstandingly high average of over 20 violent scenes per hour.  [10]   According to IMDB (Internet Movie Database) which is the third largest online database containing information mostly about movies and television programs and is considered to be one of most popular online entertainment destinations with over 100million unique users each month and over 41million registered users, where viewers are able to rate and comment on any television shows theyve watched  [11]  . Some of the top rated, and most frequently watched cartoons by preschoolers in America such as Teenage Mutant Ninja Turtles, Tom and Jerry, Ben 10, The Power Puff Girls  [12]  , à ¢Ã¢â€š ¬Ã‚ ¦ The list is endless and it is because of cartoons like these which are believed to contain some of the highest and most prominent levels of violent scenes from which the question on whether overexposure to such content may have any unwanted outcomes, arises. Among the most popular cartoon broadcasting channels were Cartoon Network and Nickelodeon  [13]  , which display all of the previously mentioned cartoons containing noticeable amounts of violence, and are mostly portrayed during Saturday and Sunday mornings when young children in America are mostly exposed to television. These cartoons which are frequently displayed and which contain violence are often those which get people of America worrying that overexposure to such content may result in an unwanted negative influence on preschoolers. Let us look at a summary of Tom and Jerry for instance. Tom and Jerry  is an  animated cartoon  , which is mostly focused on a rivalry between a  mouse  (Jerry) and a cat  (Tom) who chase each other throughout each episode which always contains some form of violence. Tom and Jerry is said to be  one of the greatest cartoons of all time.  [14]   It is a cartoon which was created in the 1940s and still today is considered to be one of the most popular and highly rated cartoons among young viewers in the United States according to IMDB scoring an outstandingly high 8.7 out of 10 score which was voted by viewers  [15]  . It is mostly displayed during prime time hours and on Saturday and Sunday mornings on Cartoon Network where it is mostly exposed to preschoolers in America. A Parents Guide section on the IMDB website where viewers and adults are capable of commenting on various television shows indicated how most viewers interpret the cartoon to be very violent and to contain dangerous weapons and abusive behavior towards animals and people. In addition there are times where the characters die at the end of an episode and come back alive in the next episode which may cause preschoolers in America exposed to the cartoon to get a false misinterpretation of death and the consequences of the actions displayed in the cartoon and in real life. In almost every episode of this show there is some form of violent activity where objects are smashed over either Tom or Jerrys head. Toms owner was very brutal and bizarre in the way he disciplined Tom. Many of the episodes feature Tom dying at the end, but he always came back in the next episode. Guns are used very frequently in the show,  but they never really show any real harm apart from blowing hair off or grazing the characters.  [16]   Despite the tremendous amount of violence which is displayed in the cartoon, it still is considered to be suitable, and is recommended for children of all ages. The most troubling thing of all is that Tom and Jerry is only one of many cartoons which portray such prominent levels of violence yet they are still recommended for all audiences. All of the previously mentioned cartoons (Teenage Mutant Ninja Turtles, The Power Puff Girls, Ben 10) all contain some sort of violence, usually in the form of aggressive physical force in order to prove a certain cause, or to defeat the evil characters. While examining the effects violence in cartoons on children, Haejung Paik and George Comstock found that all children, including preschoolers in America, demonstrated increases in violent behavior and manifested aggression when they were exposed to violent content from cartoons. Various studies conducted by the two have confirmed the suggestion that the aggressiveness of preschoolers increases after they have been exposed to a cartoon which contained some form of violent content, and also where the characters in the cartoons demonstrated aggressive behavior.  [17]   A Study conducted by psychologist Albert Bandura showed how this information which was gathered is linked with the social learning perspective indicating that preschoolers learn to behave by observing other people or characters in their surroundings and try to imitate how they would react in certain situations.  [18]   Bandura also found that the aggressive behavior which young preschoolers were demonstrating was mostly coming from violent cartoons. He concluded that children were behaving aggressively towards others because they tried to simulate the actions of the characters which they saw in those cartoons. He discovered that this behavior which the children had observed from the characters, had then been generalized into other forms of violent deeds by the preschoolers themselves such as aggressively playing with plastic swords and guns.  [19]   Bandura and Huston found that the observation of violent and aggressive acts in cartoons by 3-5 year old children in the United States, regardless of which character was involved and what connection they had with the child, was a sufficient condition for producing imitative aggression  [20]  for preschoolers. Moreover children who have been known to watch many cartoons containing a decent amount of violent activity are more likely to express some form of that aggression towards their peers or even adults, in contrast with those children who do not view much violent content in cartoons.  [21]   Bandura has conducted studies showing that those actions by the characters in cartoons which are rewarded are more likely to be remembered by the preschoolers, rather than those which are punished.  [22]   A report by the NTVS (National Television Violence Study) showed how almost 70% of violent acts in childrens cartoons did not result in any harm or pain to the characters who were involved. Another study also showed how less than half of the childrens cartoon shows had any form of punishment for these violent and aggressive actions of the characters.  [23]  As a result the violence which young preschoolers view from cartoons on the television may give them the wrong impression of what the outcomes could be in real life and in a real-life situation. The preschoolers are able to see how in most cartoons when an act of violence is implicated by one character towards another, the one who has demonstrated a violent or aggressive act towards the other character does not get punished for his/her actions in most cases, and does not suffer any consequences. In fact, in the cartoon Ben 10, the main character (Ben) destroys large amounts of the city in some situations including public and private property and inflicts damage in order to capture the villain, this mass destruction always goes unpunished, which may leave a false impression among young viewers that just because one bad guy was caught might approve or act as a justification for the destruction of other peoples property or hurting others. In fact the most common way of teaching moral lessons by protagonists in cartoons is by aggressive or violent acts.  [24]  This type of behavior is often rewarded and the character is considered a hero when he defeats the bad guy by using various forms of physically aggressive force such as the Power Puff Girls, who always inflict severe amounts of damage with their super powers in order to defeat the villain/s and are always considered heroes and are praised after every episode. Such cartoons in which the acts of violence are rewarded although in some cases are considered to be extremely harmful or pain inflicting, mislead the young children in perceiving those acts of violence as the right thing to do. By watching how the characters can almost always get away with it, and seeing how that sort of behavior is usually rewarded in the cartoons, the preschoolers in America might get the wrong impression of how they should be reacting in specific situations, and how they should be treating and behaving around others in their surroundings. Children often view the characters they see on television as their role models. They consider them to be heroes and observe how they are rewarded and praised for committing violent acts as well as possessing not only very aggressive attributes, but the characters also consisted of very attractive and appealing qualities as well.  [25]  . This leads preschoolers to draw conclusions that the aggressive behavior by their favorite characters is justified since there is no form of punishment, or consequences to show that it is wrong, as a result the 3 to 5 year old children have an increased motive to try and reproduce this behavior.  [26]   Many people fear that overexposure to cartoon violence may have long term effects on preschoolers behavior in America, especially if they are consistently being overly exposed to violent content in cartoons at such an early age.  [27]   There are many different theories suggesting what possible effects overexposure to violence in cartoons could have. Professor Dolf Zillmann developed his excitation transfer theory which suggests that while children are watching television or cartoons containing violence, they suddenly feel a need to transfer negative energy towards something/someone else, resulting in antisocial behavior and perhaps inflicting damage to other children in their environment.  [28]  Another famous theory founded by Professor George Gerbner was the cultivation theory which indicates that overexposure to television increases the likelihood of a mainstreaming effect where young children might confuse what they see as a twisted representation of the real world and real-life situations,  [29]  Which in turn may result in children developing a misinterpreted view of violence in the real world.  [30]  John Flavell, an  American psychologist, discovered that the understanding which preschoolers p ossess regarding whether the cartoons they watch on the television are real or imaginary is either very limited or not present at all. Meaning that there is a very high possibility for those young children to confuse reality from fantasy and comprehend what they see from cartoons as real.  [31]  Accordingly it has been discovered that 6-7 year old children had difficulties understanding the distinction between real world capabilities and those portrayed in cartoons and that they appear to have difficulty understanding television conventions that violate real-world possibilities.  [32]  We can form judgments from the previous findings because if 6 and 7 year old children arent fully capable of understanding the conventions on television and linking them with the real world, then preschoolers, being of a much younger age and generally unaware of the meanings of the events taking place in cartoons, would have an even poorer understanding of what they are watching and what possi ble connections it may have with the real world. It has been discovered that when a specific character in a cartoon exhibits aggression or acts violently towards another character, and at the same time provides a clear explanation justifying the reasons for his/her actions by the use of words, was far too intellectually advanced and overly complex for young children in between ages 3-5 in America to interpret and understand completely.  [33]  This may leave the preschoolers with a false memory or intuition of only an aggressive or violent act by one character towards another without any reasoning or justification involved. In order for young children to become fully capable of understanding the reasons behind the actions of the cartoon characters and their intentions, they need the assistance of an adult who is willing to explain the means of the situation and why the use of aggression should or should not be punished, and what possible consequences would be necessary to the characters who have demonstrated some form of aggress ion towards others.  [34]   Ronald Drabman and Margaret Thomas found that children lose all forms of sensitivity and feelings towards victims in cartoons by the time they leave preschool,  [35]  which could mean that the young 3 to 5 year old children are finally becoming capable of distinguishing reality from fantasy, and that they are becoming aware that the cartoon characters are not real. While on the other hand this information could mean that the children have lost interest or possibly gained the wrong impression of the consequences of the actions of the characters. E.g. if they watch a cartoon in which one character shoots another character, and the other character does not receive any injuries of any kind then the children may mistake guns for being incapable of inflicting any damage to other people in real life which could lead to serious consequences. While looking at the unrealistic capabilities of most characters from cartoons, in their fantasy worlds, we cannot really determine whether this violence is considered harmful to young children. Even though not all television networks and adults, especially parents approve that they are comfortable with the amount of violence depicted in cartoons, many older and mature people who watch adult television comprehend cartoons and fantasy as something which has nothing to with extreme violence what so ever, and so they do not find young children being exposed to this type of content worrying.  [36]   In fact Some of the worlds largest and most famous television networks such as Warner Bros. also characterize cartoon episodes to be a reflection of good versus evil that particularly underline the importance of loyalty and how punishment for being selfish is necessary under certain circumstances.  [37]  Consequently the violence which occurs when the good characters have to defeat the evil characters is justified because it is the morally correct thing to do, and these cartoons try to pass on the message how in order for a whole community to feel safe and enjoy their lives, some people have to suffer and be punished. Research shows that when children are able to interpret a cartoon with real life and compare the scenes which occur in the cartoon with real life situations, then there is a greater chance for the child to demonstrate aggressive behavior. Whilst on the other hand if the Childs understanding of the cartoon is rather poor and in their eyes is seen as unrealistic, then the chances of the preschooler showing any forms of violence or aggressive behavior, is significantly lower.  [38]   Research is continually proving that children in America between ages 3 and 5 do not completely understand the meaning of the cartoons they watch and that their apprehension of the shows they are being exposed to is very poor and could remain that way all the way through to until they are 8 years old.  [39]  By looking at this information we can conclude that because preschoolers have a poor understanding of the meaning and the plot of the cartoons which they are watching, the chances of inheriting any unwanted aggressive or violent behavior from those cartoons by the preschoolers will be significantly lower. A study performed by Hodapp showed how 5 and 6 year olds could not recall what they had learned while watching educational programs and how they were simply incapable of performing and putting those skills to action in real life in order to help themselves in difficult situations.  [40]   Therefore this leads us to a conclusion that preschoolers, being of a younger age and not as intellectually advanced as a 5 or 6 year olds, may also be incapable of interpreting the actions they see in violent cartoons. So as a result they will not acquire any negative influences or bad behavior from watching cartoons containing violent and/or aggressive scenes. Moreover the National Television Violence Study (NTVS) reported that for all cartoon programs, just over 30% of the characters who demonstrated some forms of violence in cartoon shows, also possessed some good and sympathetic attributes such as helping and caring for those in need  [41]  , which could be beneficial for preschoolers in America and teach them to exhibit concern and empathy for others in their surroundings. Judging by their age, preschoolers have been proven to have a relatively high ability of drawing conclusions about moral reasoning  [42]  such as recognizing and determining when the character has acted selfishly or whether their actions are morally wrong.  [43]   The preschoolers in America are known to be capable of identifying the difference between morally acceptable and unacceptable behaviors in society.  [44]  Meaning that they are aware of the rights and welfare of others in their surroundings and how they should be treated equally and with respect. In addition the investigators of this topic believe that 3 to 5 year old children are fully aware of the distinction between socially acceptable and socially unacceptable behavior and how they are capable of making judgments based on whether it is real life situation of something theyve seen from a cartoon.  [45]   This understanding of such situations at an early age may aid young preschoolers in finding a balance between the violence they view in cartoons and real life situations and it may not result in a negatively affected behavioral development in the future. Conclusion Does the violence depicted in cartoons have a negative influence on young viewers between ages 3-5 in America, and does it promote aggression and/or violent behavior. answer the research question. Throughout this investigation we have discovered that children between ages 3 and 5 in America may have difficulties when attempting to differ reality from fantasy which might intensify or negatively stimulate the preschoolers motive to act and behave differently and aggressively towards others in their surroundings. However we cannot conclude that a preschoolers aggressive or violent behavior is the result of being exposed to violence in cartoons. In order to make such assumptions we must first take into consideration the childrens perception of the violence depicted in those cartoons and the way in which the preschoolers understand what is happening and why. Therefore we cannot confidently say that the children will show similar behavior in the real world only because the characters may have acted aggressively or violently in the cartoons. When we focused on the most popular cartoons among preschoolers in America we found that they are clearly violent and how they might potentially influence the behavior of the young children in a negative way. However we also found that some of the acts of the characters could teach the preschoolers in America to act morally and to apply the skills they observe from television in real life which could be beneficial. In order for us to summarize the effects of cartoon violence on preschoolers in America it is crucial that we first determine how well the children understand and what they learn by watching cartoons. We found that if the children are capable of differentiating the transgressions which are present in the cartoons from those in real life and if they realize a distinction between socially acceptable and socially unacceptable behavior which they view in cartoons, then cartoon violence would not have such a negative impact on the behavior of the preschoolers as assumed. All in all cartoons which portray large levels of violence and aggressive activity will continue to do so and will remain a popular source of entertainment among the 3 to 5 year old viewers in the United States. The children will continue to spend most of their free time watching these cartoons which will perpetually be displayed on television during prime-time hours and throughout childrens weekend morning shows. Adults, especially parents in America play a vital role in influencing the impression preschoolers obtain by observing potentially harmful scenes in cartoons and the violent actions portrayed by the characters as an act of justice, and determining the moral and social acceptability of those actions. All in all the impact that overexposure to violent or aggressive content has on the more vulnerable audiences in the United States such as 3 to 5 year old children will remain unresolved as we have found evidence supporting both sides and various different views towards the topic and the possible effects which cartoon violence might have on preschoolers in America. I would suggest that adults watch cartoons alongside the children as they will then have the opportunity to answer any potential questions the children may have, and with the aid of an adult the children may interpret and gain a more clear understanding of the motives and reasons for the violent or aggressive actions which have been depicted by the protagonists in cartoons, therefore minimizing any possible unwanted outcomes.

Panoramic Poe Essay -- essays research papers

The written word has been the vehicle by which generations have articulated their hopes, fears, aspirations, and nightmares. Amidst these ideas, the author must weave together history, culture, environment and atmosphere to produce a setting in which their ideas will develop. This setting is crucial to many stories, including Edgar Allan Poe’s â€Å"Cask of Amontillado.† Poe shrouds the reader in the warmth of a celebration and the coldness of death with only his words as a guide.   Ã‚  Ã‚  Ã‚  Ã‚  Poe starts out by introducing the reader to a carnival like atmosphere reminiscent of Mardi Gras. There are people in multi-colored jester outfits, people wearing masks, and the overall feeling of festiveness. This jovial atmosphere is greatly contradicted by the Montresor’s vengeful mood. The contrast of mood to setting creates a sense of chaos, somehow signifying an underlying madness in the character.   Ã‚  Ã‚  Ã‚  Ã‚  Another important aspect of the carnival setting is the wine. At the carnival itself, liquor is free flowing and most people have indulged themselves, including Fortunato, Montresor’s bane. This particular feature in the setting allows Poe to set up the events that unfold in the story. Fortunato, intoxicated and somewhat vain, insists upon seeing the Amontillado rather than have Montresor take it to someone else. At this point, the carnival setting has served its purpose in setting the mood and the circumstances of the story.   Ã‚  Ã‚  ...

Dispersion and Deviation

In the world of info analysis, it is important to believe note of the discrepancy of info set for computation. Technically, disagreement provides an outlook whether there is a authoritative condition that data follows to pass a certain computational characteristic. It comes from the showtime word vary and depicts a thought to analyze whether data sets are varied from each other or not. Usually, unevenness can be structured among at random selected numerical values and intends to measure how disruption out a group of data is (Lane, 2003).Dispersion is considered to be a measure of variability because it provides a big picture of how at sea the data values are. In concourse data sets, there is always a possibility for the numerical values for them not to align in a certain average. Therefore, dispersion gives the researcher an idea how astray dispersed each of the data is with treasure to each other. Another measure of variability is deviation. parenthesis is the actu al distance of a measurement data from the average of the alone data set or the taut (Wiley, 2000).There are two forms of computational deviation, the variance and the standard deviation. The variance is the average of the square deviation deliberate from the population or sample average ( booster cable Trek, 2007). Meanwhile, Standard Deviation is the variances square root. In the research that intends to provide alternative manipulation Educational Course for Parents of Children with Attention dearth Hyperactivity Disorder, the possible areas where variability can be seen is with regards to the vari qualifieds involved under measurement.There might be some variations about the effect of the parents sexuality to nurturing their child with ADHD. Variation between the virile and female perspectives can be measured by using implicit data acquisition such as surveying, interviewing or experimental design. Another possible solution of variability can be considered in the educat ion background of the parents. People who were able to complete their education and people who flip not will more credibly result to some variations with their answers on the surveys, evaluations and judgment on the proposed alternative treatment for ADHD.ReferencesLane, David (2003).
