Exploring the Dark Side of Human Nature in The Killers Essay -- Killer

Exploring the Dark Side of Human Nature in The Killers Hemingways The Killers illustrates that unexplained violence is an integrated part of society. To acknowledge the cruelties of vitality is to come to terms with horrifying events that can not be denied. A person may lack the maturity to cope with everyday life if they do not realize that evil can exist in any given society. The story is told in the objective point-of-view. Hemingways approach to his story is different he approaches it as a journalist approaches a news story, from a focal point somewhere outside of his characters (Jaffe, 209). The author tells the story only as an observer. He does not tell the reader what the characters are thinking, nor does he give the reader any insight to his personal feelings. As the story progresses, the reader learns that The Killers intend to await up to the label Hemingway appropriately gave them. The Killers, however, are not the main focus on of the story. The title is symbol ic only of the evil that the story revolves around, but the main focus of the story is Nicks discovery and disbelief of the true evil that lurks in everyday life. Nick struggles with the knowledge that he can not change Oles fate as he states, Dont you want to go and see the police?...Isnt there something I could do?...Maybe it was just a bluff...Couldnt you get out of town?...Couldnt you fix it in some way? (Hemingway, 251). He is not mentally prepared to accept the darker side of human nature. It is a story of discovery, in which the anonymity of the observer serves to fetter the readers attention to the bare facts as they add up, one by one, to a pattern of demonstrated yet... ...rld, they will be over-burdened with the unfairness of everyday life.

Direct-to-Consumer Advertising Essay

Direct-to-consumer (DTC) advert of prescription drugs has become common place in todays society. Every ho purposehold with a television is awake of DTC advertising as they interrupt their nightly programs. Every national magazine or local newspaper offers advertising on the latest drug furbish up for what ails us. This multi-media approach is relatively new for pharmaceutical companies as previously such efforts were directed all at physicians who were the sole decision makers when choosing medications. With the 1997 change in the food and medicine Administrations (FDA) guidelines a pine with perseverings desires to be more involved in their own c be and treatment, drug companies have expanded their promotional efforts to complicate the consumer. This essay will look at some of the current regulations concerning DTC advertising, pros and cons of these ads, and the estimable issues that arise from DTC advertising.RegulationsDirect-to-consumer (DTC) advertising is the promotio n of prescription drugs through newspaper, magazine, television and internet marketing. (Direct-to-consumer advertising, 2010) These ads ar directed towards the end utiliser, the consumer, and not the prescriber/physician. Prescription drug advertising has been regulated by the U.S. Food and Drug Administration (FDA) since 1962. Their Division of Drug Marketing, Advertising, and Communications (DDMAC) is amenable for ensuring that companies that directly advertise to the public are providing randomness that is truthful, balanced, and accurately described. (FDA, 2010) Even though the FDA has oversight on DTC advertising, it should not impose unnecessary restrictions on them as they fall under the category of commercial speech protected by the first amendment (Evans & Friede, 2003, p. 387). The Federal Food, Drug and Cosmetic Act requires that some(prenominal)one who makes, packages, or sells prescription drugs for domain moldiness happen upon information in their advertisement s about the products uses and risks (U.S. Department of HHS, 1999, p. 3).This information disclosure is called the brief summary. Contrary to its name, the brief summary is earlier lengthy as it must contain all risk associated with the drugs approved use. Prior to regulatory changes made in 1997, these disclosures had to be included in every advertisement making television commercials impractical due to the restricted amount of time available. Now there is a distinction between print and spread out advertising so that only print ads must contain this brief summary. The DDMACs 1997 revisions now only require audio and/or visual ads to disclose two things. The drugs major risks in consumer-friendly language, the major statement, and give adequate provision for the consumer to access the full product labeling (U.S. Department of HHS, 1999, p. 5). This raise be achieved by providing a toll free number to call, referencing the full advertisement in a print ad, or making sure brochur es are easily accessible international of a physicians office, like a pharmacy or grocery store. By decreasing the amount of information ask in these ads, commercials shortly became a viable form of marketing.Advertisements markn on television or in magazines are not required to be submitted to the FDA for approval prior to their release however, companies must submit their ads to the FDA when they first appear in public. The FDA is available to offer their advice to pharmaceutical companies when asked for help (FDA, 2010). Once they see the ad and if they feel that it violates the jurisprudence, they will send a warning letter requesting that the company stop the ad immediately. These letters are posted on their web site for public inspection. The drawback to this process is that an ad that violates the law whitethorn be aired without oversight. If the warning letters do not rectify the situation, the FDA can work with the Department of Justice to seek injunctions against comp anies, or criminally prosecute firms. (Vogt, 2005, p. 26) The FDA also has the authority to seize drugs that it deems as misbranded and can even reverse approval for the drug.ProsThere are numerous arguments on the benefits of direct-to-consumer advertising. Supporters of DTC advertising contend that ads can be educational, domiciliate alpha health information, and generate sales to further necessary research and development (R&D). One of the most usually heard reasons is that DTC advertising has assisted consumers in identify(ing) disease conditions and engage(ing) in more informed conversations with their health care providers. (Pfizer, 2011) Supporters uphold that this advertising helps the doctor/patient kindred by existence a conversation starter spareing discussions on disorders and options that a patient whitethorn not have known how to talk about earlier. approximately patients today are educated and desire a greater level of involvement in their healthcare choices. DTC advertising gives the consumer power through knowledge. Important health information can be delivered in DTC advertising. These ads have the ability to reach millions of consumers relatively easily.Through print and media advertising, pharmaceutical companies can play a serviceable role in raising awareness of certain conditions and disorders. Raising the publics awareness can promote consumers to seek medical attention when they otherwise may not have. Seeing these conditions on television or in a magazine can lessen the stigma associated with them. Large pharmaceutical companies use the money made from DTC advertising to fund their R&D. This research and development plays an integral part in ensuring a drugs safety which in turn saves generic wine companies from needing to repeat R&D on the same drug. This makes generic manufacturers another supporter of DTC ads. By advertising new, name brand drugs, companies are causing a demand for the medication. Once the drug has los t its patent, physicians can begin prescribing the less pricy generic alternative. The generic manufacturer has benefited by default on the king-sized pharmas campaign.ConsThere are an equal number of allegations on the negative effect of direct-to-consumer advertising. Opponents of DTC ads argue that ads can be detrimental to the physician/patient relationship, increase medication costs, and harm public health. Those against DTC ads feel that they have the potential to change the way doctors and patients interact with each other. A patient may see a particular advertisement and be convinced that they have a certain condition or that they need a specific drug. The patient may then present to their doctor feeling that they have diagnosed themselves and request prescriptions even if not needed. The physician may then feel pressured to oblige the patient rather than discussing other, possibly cheaper or drug free, treatment options. This scenario can lead to over-prescribing and over -use of a particular drug based on the effectiveness of the advertisement. Others have argued that advertising is expensive and the pharmaceutical companies have to recoup their cost somewhere.This leads to the cost being passed on to the consumer in the form of higher prescription costs. The amount of money spent on DTC ads has increase dramatically from 1997 to 2005 from $1.1 billion to $4.2 billion (GAO, 2006, p. 12). This increase expenditure could create higher healthcare costs across the board. Another cost of DTC advertising could be at the expense of public health. Most consumers lack the specialized knowledge required to evaluate the content of these ads and therefore take them at face value. They may not be fully aware of the harmful side effects or interactions of the drug. DTC ads can be seen as misleading since they are not required to mention other alternatives like diet, exercise or other preventative measures. These alternatives could treat the advertised condition w ithout medication. By not including the alternatives, companies are advocating drug use as a primary response to medical conditions.Ethical IssuesPharmaceutical companies have a substantial obligation to ensure that their direct-to-consumer advertising is ethical. Their products not only have the ability to help consumers but they may also cause potential harm. Advertising of a drug is not like advertising of any other product where you are trying to convince the consumer to buy something they dont need. Drug advertising needs to educate the consumer while still promoting their product. sight tactics therefore should be ethical. How does one go about knowing if DTC advertising methods are ethical? In the book Persuasion Theory and Practice, ethical persuasion is defined as a communication activity that permits maximum individual choice (Anderson, 1978, p. 3). The key is that the consumer must be able to make a voluntary choice without feeling coerced. DTC ads should not rely on de ceptive or manipulative tactics. As previously stated, the consumer can be viewed as a vulnerable audience if they are being spoken to at a level that is beyond their ability to understand (Baker & Martinson, 2001, p. 166).Ethical marketing requires that these audiences not be unfairly targeted because of this vulnerability. DTC advertising ethics is concerned with what drug companies ought or ought not to do. Lying is morally wrong and therefore considered unethical. Using lies or false impressions in a DTC ad distorts the information a consumer receives and can alter the choices they may make (Baker & Martinson, 2001, p. 160). Therefore DTC ads should not create false impressions or omit disposed(p) information just for the sake of the ad. The point of DTC advertising should not be increased sales but be more of a means to an important social end which should be consumer education.An example of an ethical advertisement would be one that utilizes those messages that demonstrate re spect for the consumer to whom they are directed. Respecting the consumer means that their needs are fixed before the needs of the advertiser. Currently, the DDMAC does not regulate the ethicalness of pharmaceutical advertising. Their mission statement is, To protect the public health by assuring prescription drug information is truthful, balanced and accurately communicated. (FDA, 2010) Ethical ads tell the truth about their product and do not try to distort its capabilities or hide its defects. (Vaux) Unfortunately an ad can be truthful and still be considered unethical. Ads that play to base human emotions such as fear can be considered unethical as they are just trying to promote emotions that would cause the consumer to seek relief through the advertisers product.ConclusionDirect-to-consumer advertising has been integrated into our culture and is potential not going to go away. Just as there are those who lobby against these ads, there are an equal number of proponents who sup port them. Regulations have been changed to allow the advancement of these ads to their current place in our society. As such, the DDMAC is invariably monitoring DTC ads and will need to be the ones to set ethical boundaries and ensure theyre being adhered to. Consumers must evaluate pharmaceutical ads critically so as not to be persuaded as much as they are educated. Although proponents of DTC advertising argue they provide important consumer information, too frequently the ads can operate dysfunctionally by providing misinformation and inducing the consumer to make purchases that are not in either their short or long term interest. (Baker & Martinson, 2001, p. 151) Ethical DTC ads should serve an educational purpose first and a promotional purpose second.They should offer consumers information on alternatives along with true representations of the risks their medications may have. Unethical ads are those that may try to point out your flaws, i.e. depression, and then tell you the y have the answer, i.e. Prozac. These unethical ads will use your emotions to cause you to believe you are in need of a fix when in reality you may not be. I believe there is a place for direct-to-consumer advertising. Consumers are constantly looking for more and more information to help them make better informed decisions.DTC ads, when done appropriately, can be used to provide this information not only about medications but health conditions as well. Decreasing public stigma around certain health issues is another advantage advertising can bring especially if it opens doors for patients to have difficult discussions with their doctors. That being said, I believe that a balance lies with the FDA needing to take a more proactive role in how they manage DTC ads. I think that all ads should be required to go through a pre-approval process rather than the current release and retract method. It is great(p) to take back something that has already been seen and that may cause damage to the consumer.ReferencesDirect-to-consumer advertising. (2010, June 11).

The awesome and surprising burst in this ac play along is its ability to rapidly grow and compete perfectly in the global market non alone that, it has achieved its documentary in that competition as you will see in the paper.The contents of this research are four parts, in the first part we will scram you through how the company started and expanded to the global market up to United State of America, vision and mission of the company in the market place. In the morsel part you will see how the PEST and some early(a)wise driving forces has effect the company operations in United States and other countries, while reaching part three the research will show how the companys segmentation, distribution, pricing and product scheme are being perform, and we shall conclude with a comprehensive summary, epitome and present the results that we have got through out our research.The unifying them in this research is the company ability to compete in a higher matched environment like ground forces not only that but resulting on generating revenue and adding value to its original capital, the company also can be count as one of the vaingloriousgest flight companies in the world overdue to its capability and diametriciation in the market place. Finally, lets hope that our research will be a vital added value to previous researches in the same matter.PART ONE 1.1 About flight Emirate The beginning of Emirate flight goes back to 1959 when Sheikh Rashid Saed the semipolitical sympathies official opens the Dubai international airport and announces that Dnata company with only five staff will be in charge of ground handling services, in 1978 Mr.Manrice Flanagan was positive by Sheikh Rashid to be the general manager of dnata company which is the operating company for flight Emirates, Mr. Flanagan later on in 1984 de abridge how the company could perhaps move to serve in air service, and with acceptance of Dubai political relation the company requested Pakistan international airline to lease them two aircrafts, the deals were struck to fly into Karachi, new-sprung(prenominal) Delhi and Bombay in India. In 1985 Sheikh Mohamed gifts two Boeing 727-2005 to the airlines, these two Boeing change magnitude the operations where the airline was able to fly to more than twenty countries.Sheikh Ahmed later on in 1990 signed an agreement with Asian Aerospace exhibition in Singapore to add airbus A310-300s to the company. In 1992 Emirate flight become the first airline to install characterization system in all seats in all classes in the same year the France government capture officially the flight to operate in the country, by that time the companys work forces become 11,000 employee. Ten years later exactly in 2011 the company managed to fly to more than long hundred destinations world gigantic, and bring downed a profit of ($1.6 billion) and bought the largest Boeing in history 50777-300ER. Flight Emirate as part of its marketing strategy has helpered number of events and competitions e.g in 2012 the company sponsor Tennis in united state and cricks Indian premier league. As we mentioned earlier the Dnata Company headed by smart board of directors is not an easy company and the proof is that its ability to raise the capital to $ 2 billion and the workforces from 11,000 to 62,000 employees in 2012 as it was the virtually profitable year for the company. The company presently call the Emirate group and consist tw o parties Emirate and dnata company and has expanded into many business for instance, hotels, workshops and tourism and the are operating all over the world.1.2 Flight Emirate in North and South America Flight emirates operates in North and South America challenging Americans airlines in delivering air services it flies to Brazil, Chile, Mexico, Peru, Urguay, Canada and United States, indoors the United States the company operate in more than six states creating a competitive environment and adding valuing advantage to this market.The free market economy adopted by United States is a difficult market to compete in if you dont have a competitive advantage, the flight emirate with its rumness and appropriate tactics has a fates of winning games as we shall discuss it later on in part three, and you will realize that the company has attracted the market using different approaches.1.3 Flight emirates focussing orientation toward global business Flight emirate as we stated earlier in our introduction started as a small company call dnata in Dubai, therefore the commission structure in the early 1950 was regiocentrics but after the Dubai government ontogenesisd the capital and instructed many deals the company management changed in 1960s to be geocentric orientation as the views the entire world as a potential market and strive to develop their blur and integrate in global market. The reasons why we categorize the company as a transnational company are the followings (1) The company operates in more than vitamin C countries and flies all over the world. (2) The companys work forces are more than 62,000 employee spread in six continents. (3) The company assets i.e (flights, workshops, hotels etc) are not all ground in Dubai. In conclusion to this regard the emirates company management can be classified as a combined of two management structures, reogiocentric and geocentric beca exercise in its starts the focus was regionally but later on they progress in global scale till they adapt the geocentric orientation structure.1.4 Flight Emirate vision and mission Vision The vision of flight emirate is very simple as we mentioned earlier the company started as ground services company in 1940s but after Dubai government decided to inject more capital the business increases and ambitions become more than just being a ground service company therefore in 1960s the company decided to focus broader in flight services not only in Dubai and in the region but even globally. Now the vision is to be a leading company in flight and tourism world wide providing excellent, safe and customer satisfaction. MissionThe mission of the company is to ensure that the flight is the choice of every traveler and to create a business competitive environment and add valuable service to the market. Differentiation, opportunities and development of a star brand in the Gulf region and all over the world is the declare one self of the companys todays focus.PART TWO The Business Environment 2.1 Political, Economic, mixer and Technological analysis (PEST) The business environment where the company operates is an big situation that we have an obligation to express in this research, many forces drives and affect the market place of any operating company, to analyze the situation we read the political, economic, social and technology changes.Political and Economic feels The country where flight emirate generated from is United Arab Emirate in middle east one of the worlds largest country in fossil oil production, the economic growth and political stability are the sign of advancement in that country. UAE currently undergoing rapid expansion in investment and private venture, the government made number of commitments to strengthen and reform its investment regulatory and make conducive environment for exports and imports. United States and UAE are strongly partners in many political alliances, economic benefits, social and cultural activities the exchange numerous of interests in regard to these issues.Politically, the family relationship between the United Arab Emirates and United States has been positive and productive for more than 30 years they are a reliable allies in many military, economic, and social affairs, the United State view UAE as source of stability, tolerance, innovation and a leading figure in the Gulf region. After the US tragedy in September 11 2001 where 2,996 including highjackers killed, the US foreign policy changed a mete out including the relationship with UAE based on the fact that two of the hijackers were from UAE, immediately after the attack the background security checks for an Arab visitors was very high and research shows how some harassment and hates developed against Muslim in US. In conclusion to the political environment where flight emirates operates i,e in US there is no negative impact due to the strong and smooth relationship between the two countries. Economically, the UAE is th e US single largest export market in the Middle East with $1.5 billion in 2011 most are machinery, aircraft, industrial and other valuable items, US imports from UAE in 2011 was 2.44 billion most are crude oil, aluminum and other things.The US petroleum companies play a big role in development of UAE energy sector, more than 800 US firms are operating in the UAE investing in different sectors and injecting UAE market with new jobs and opportunities of Arab youth. The research also found that the US, UAE relationship is a long term partnership and each state in US probably has its aver trade relationship with UAE. Research also found that UAE is the larger operator of Boeing 777 aircraft in the world, in November 2011 Emirate flight placed an order for $ 24 billion record breaking for 50 Boeing 777-300 ERs, beforehand that there were number of orders for purchasing Boeing from US which make the company the most consumer of this type of flights.In conclusion to economic relationship between the two countries, the flight emirates is the worlds largest operator of Boeing 777 and serves non-stop flying from Dubai, also the robust trade and investment relationship between UAE and USA is based on the political stability and diplomatic understanding. Socially, the UAE and US have a lots of social partnership in numerous of activities, UAE is an open country for visitors and sound immigrant, its population is extremely liberal and open minded society compare to the other countries in the region, UAE attracts many investors and tourist including US citizens, the US population in UAE estimated to be 4,000 people working in different sectors of production.UAE population in USA is recorded not to be affected by any violence or discrimination against any human right because US treat and protect the entire resident equally but unmarried harassment does subsist because of personal behavior. According to researches, after September attack where two were from UAE as we sta ted earlier the Americans views on Islam and Arab has changeed a bit of which number of travelers to and from Arab world has decreased. Technologically, as technology refers to the application of science and research into industrial or commercial objective, it has affect societies all over the world, flight emirate in its existent relies on technology in all its operation and has benefit so much in US market on this matter, marketing customers service and other operation are possible in flight emirate because of technology and the latest news in this regard is the announcement of the company recently that it will allow all the passengers to use their cell phone in its all flight operating in US market very soon, that could not be possible if the company was not connected with USA. To conclude this topic technology has not negatively affected the operations of flight emirate in USA, it has really been a source of inspiration for the company.2.2 The substance of Culture and Sociology In United States market culture as (education, religion, values, attitude etc) play a big role in business place, flight emirate with its unique study of Americans culture has found it a useful environment to operate in, US is a multi cultural community where different ethnic groups coexist without any discrimination. US market is a free economy where competition is the only factor that can push you to the top or dismantle you down, flight emirate adapted those diversities and without any exclusion and that is why it has been able to compete with US fight companies in the market place, as we stated earlier the only side effect on flight emirate in US market was what follows September attack when a group of terrorist from middle east and with Islam background hijack US flights and threaten US as a sovereign country, the result on that was the reduction of travelers from and to Arab countries, raising the searching system which actually targeted travelers from Gulf countries and in dividual harassments by some indigenous citizens.In conclusion to culture and sociology the company does record much challenges in US market based on these aspect but the following points are what we think to be the companys threats in US market 1-Flight emirate generated from Arab country therefore it might be a target of terrorist and use as a cover to make insecurity in USA. 2-Services in the flight emirate are indirectly affected by Islam as the crew do welcome passengers by Quran prayers on board, this activity does not satisfy non Muslims on board. 3-Wearing of AL hijab by Arab women is not an acceptable sign by some people. 4-Citizens of UAE started to avoid traveling to USA because of long waiting visa due to background security checks.PART THREE THE COMPANY merchandising PLAN 3.1Marketing (country) selection and entry strategy Flight emirate operates in more than one hundred countries and flies over six continents, the research has an interest in US market and here are the reasons why the company chosen to compete in US industry -The airline copes and encourages free competition with other market player using a strategy known as the open skies strategy. -The political environment and the strong relationship between USA and UAE encouraged flight emirates to choose US as useful market to operate in. -USA is an open economy where the market competition is the art of the game, flight emirate with its choice services and competitive advantage choses to be part of it. -US dollar is the most powerful currency in the world, since the company adopted this currency to be the company main fare in its all operations than the company got it profitable to operate and expand in US market. -Flight emirate benefit more from long get behind flying which also save fuel consumption as well as non-stop flying from Dubai to USA is profitable. -The Boeing 777 is the major aircraft used by the company thence all the accessories, parts and maintenance is cheaper and availa ble in United States. The above reasons plus the growing business opportunities between US and UAE has increases the demand for direct flying from Dubai to United States.3.2 Segmentation, Targeting and positioning Flight emirate like any other flights in the airline industry has a specific strategy on targeting and positioning its self in the market place, below are the airline targets 1-Emirate flight is one of the big airline in the world, the rapid growth of Dubai and its good relationship with other countries curiously US had given a chance to the company to position it self as the major carrier between the two countries and inside the US, the company currently operates in eight states in US market targeting the following segments 2-The demand for traveling to Dubai by tourist and business people has increased and especially in summer session where Dubai attracts more than seven million tourists.3-Expatriates, because Dubai is a working environment and highly paid city, the dem and for people to travel to and from Dubai increased hardly, many US citizens live and do business in Dubai while the also regularly visit their homes, therefore flight emirate is playing that role of targeting those group. 4-Transit passengers, before the haul long flying strategy being implemented by many companies were suffering from waiting hours, passengers from US did fly to middle east or Dubai connecting through Europe, flight emirates made it easier to dominate this segment by offering direct flight between Dubai and USA and found it very profitable. Because of demand increase within the United States, flight emirate with its quality services and golden brand attracted those groups and the company positively responded and got it much profitable.3.3 Information and research strategy The aim of this strategy is to keep the company growing and competitive in the market place, the information and research are the heart of any successful company, it explore opinions and attitude of customers and allow the company to predict the future result of the companys operations. Flight emirates value information technology and research and has invested a huge of amount approximately $200 million and deployed 2,200 employees, recruited from the most qualified institutions in the world. The companys IT department and research after ensuring solutions for the company also provide services for other business in the region as the generate revenue to the company from that services.Research found that flight emirate invest heavily in information technology and research for smooth operation and acknowledging the customers needs and demand in US market.3.4 product strategy Oil prices has been un lasting and challenging in worlds market place for many flight companies to perform perfectly with out any conciliation or interruption, flight emirate has made it easier by signing a deal with several major oil companies to supply jet fuel to them all the time with a specific price , that deal remain unchangeable no matter what the future market may present, this fuel strategy has maintained the company profitability high among the competitors. The fight also gain a lot of profit base on product strategy through it designing of long haul flying, direct from US to Dubai because this kind of service attract big number of passengers of which the company provide cheap prices.In this strategy also the company has divided its portfolio into two, airport services and infrastructure, the airport service has to ensure the sentry duty of passengers baggage and belonging up to the last destination, this strategy has build confident between the company and the customers. The free competition strategy that was adopted by the company enable the customers view their opinion in the services, employee training and capacity building in the company has been a successful part of the product strategy because it keeps the sales talk of service in a high position. Buying new airc raft every short period is one of the promotion for product strategy and what kept the company delivering excellent services in US flight industry.3.5 Pricing strategy Pricing strategy is the secret of any successful company, the first thing the company does was to keep US dollar as the standard currency of exchange in the company, based on the fact that dollar is a powerful and stable currency and is convenience to all passengers regardless of their country of origin, this strategy made the companys profit always high. The company has a sufficient strategy that enable passengers enjoy cheap pricing either in short or long haul flying, this has been a competitive advantage to the company, the company has been in the market for a short time which mean the company does not charge legacy fee in its ticket because there is no clog of pension as other companies do, the well train and qualified financial managers that the company has are playing a role of keeping the financial plan in a safe environment. The most important factor that keep flight emirate cheap and profitable is the variety of aircraft that operate in different parceling this gives the passengers the option of choosing the cheaper the can afford. All the above are supported by the fact that prices of flight are not being fixed any where because it numerate on the market demand, what keep flight emirate cheap and affordable is their continuation of reading the market rightly.

Are Crises Threatening the Benefits?

Are crises threatening the benefits from multinational portfolio diversification? This essay examines whether rising international stock securities industry correlation coefficients during foodstuff crises be weakening the expertness of modern portfolio theory, which promises benefits from international portfolio diversification. The importance of the combining assets that are non dead corre recentlylyd is discussed, as are reasons why we might expect markets to move more closely during crises. If it is clear that markets are moving more closely together during crises, investors are losing diversification benefits at the most critical time.However, because of assumptions, it is apparent that there is considerable debate over the validity of the correlation coefficient for use in explaining the co-movement of market hangs. It may be that markets are moving closely together at all times. Also, over the long run, short term rises in correlations may have negligible personal e ffects for the investor. For these reasons, we cannot discredit the worth of international portfolio diversification. The correlation coefficient is a key statistic for devising the optimal portfolio.In accordance to Modern Portfolio Theory, where risk is to be minimized for a given over level of return, the correct combination of assets relies critically on the correlation between those assets. When defining the risk of a portfolio as its standard deviation, when assets that are less that perfectly correlated are combined, the standard deviation of the portfolio is actually less that the weighted average of each individual assets standard deviation, although the expected return from a portfolio is simply the weighted average of the expected return of each individual asset (Bodie, Kane, Marcus, Perrakis, &Ryan, 2008, p. 08). This is why combining assets with correlations of less than whizz (proper diversification) is referred to as a free lunch. It is also apparent that this prin ciple also extends to international portfolio diversification, where market returns are less that perfectly correlated. From examining the correlation data from Table 2, the financial crisis of the late 2000s seems to be yet another example of international stock market correlations rising during bear markets.The selective correlations of the UKs FTSE 100 Index, Japans Nikkei 225 Average, and Brazils Bovespa Index to the S&P 500 come from simple fifteen year data series on monthly exponent returns. All correlations were high from 2008 to March 2009 (the substance of the S&P 500s decline during the financial crisis) relative to correlations for the entire sample period, and even higher relative to correlations for the bull run of 2003-2008. This correlation behaviour may create misgivings for an investor who values his free lunch, and raises the questions do markets move more closely during crises and why ?When using the correlation coefficient to measure the comovement of market r eturns, we are making assumptions about the underlying data (stock market returns. ) An important assumption is that the underlying data follow a regular distribution. A study by Campbell, Forbes, Koedijk, and Kofman (2007) examined annualized mean return data for five stock indices from 1990-2005 and found that each data set failed to conform to normality, by displaying significant skewness and kurtosis.They also tribulation conditional correlation estimators under normality and under the student-t distribution, and rule that earlier studies may have overestimated the excess in conditional correlation by assuming bivariate normality, and that under the student-t distribution excess conditional correlation ceases for the left tail (bear markets) of returns (para. 4). Furthermore, Forbes and Rigobon (2002) assert that the correlation coefficient is pull ahead biased as an estimator of market comovement because of the heteroskedasticity of market return data (volatility changes), while the correlation coefficient assumes homoskedasticity.They conclude that increases in volatility during crises result in an upwardly bias in correlation coefficients during those periods. After ad meeting for this bias, they find that there is no statistically significant increase in market correlations during crises. They do find that markets comove potently at all times, which they call interdependence(p. 2250). It is important to note that Forbes and Rigobons result is not uncontested, and that they also employed their own set of assumptions, and when violated, correlation coefficients are not always biased measures of dependence when markets become more olatile(Bartram and Wang, 2005, para. 1). This illustrates the academic uncertainty of dismissing or accepting correlation coefficients as an effective measure of market co movement. It is because of the uncertainty in the literature, and the inherent assumptions of the correlation coefficient, that we cannot strictly conc lude, by examining stock market return correlations, that markets move more closely together during crises.In a study of the comovement of stock market returns during the aforementioned financial crisis, Didier, Love, Soledad, and Peria (2011) provide some insights into why shocks may transmit and manifest in different stock exchanges. They test three possible drivers of market comovement real linkages through trade financial linkages, both direct and indirect, including the actions of international investors with respect to margin calls, risk aversion, and herding and demonstration effects, where investors give new attention to risks that have materialized, and then update valuations.From their empirical tests, they find that financial variables played the largest role in transmission during the financial crisis of the late 2000s, while demonstration effects also contributed to increased comovement in the early stages of the crisis. Also, although trade linkages were not found to e xplain co movement during the period, the authors remind this does not mean that they will not play an important role in future crises (as they have in the past) (p. 2). The drivers of stock market correlation by Didier et al. do provide meaningful explanations of why we might expect markets to move together during crises, but they arent all excluded from working in the opposite direction (not just in crises). Assuming market correlations are in fact an unbiased and accurate measure of market comovement during crises, this would result in a significant damage of the benefits of international diversification during downturns.According to Butler and Joaquins (2002) test of an equally weighted portfolio amongst international markets, investors would get an annual return of 2% less than predicted by the normal distribution in extreme bear markets (5% left tail). They conclude that in this case investors may benefit from trying to predict which markets will have near-normal market corre lations during bear markets, and then weight their portfolios more heavily in these markets. Is that (potential guesswork) really necessary? According to Asness, Israelov, and Liew (2010) the answer is no, at least if you are a long-term investor.Asness et al. compare the returns of holding a local portfolio vs. an equal-weight global portfolio, where they find that a global portfolio shows lower short term volatility (for one month and one year averages) but greater skewness where simultaneous market crashes cause the global portfolios to experience worse risk adjusted crashes(p. 6). Over the long run, though, they find that holding a global portfolio provides considerable insulation from local downturns, and the skewness of the global portfolio approaches zero.They contend that in the long run countries market returns are operate by country-specific underlying economic performance, and that international diversification insulates the investor from being exposed to any one underp erforming country in concentration. This long run result gets spinal column to the premise of modern portfolio theory, that is, combining assets that arent perfectly correlated, or dont co-move in direct proportions. As we can see, it is hard to discredit the efficacy of international portfolio diversification by strictly examining rising international market correlations.Because market return data may not conform to the assumptions inherent to the correlation coefficient, there is uncertainty over its usefulness as a measure of market co-movement. Also, if the investor has a long-term horizon, the benefits from international diversification are still strong. References Asness, C. S. , Israelov, R. , & Liew, J. M.

How useful are the sources A to G for explaining why there was an anti-war movement in the United States during the late 1960s and early 1970s?

The movement against the Vietnam struggle in 1960s America was hotshot of the largest of its kind, in both bailiwick and international comparisons the movement was heavily linked with opposite reform groups which were pressurising the American government during that time period. Due to this, opposition to the contend came from a diverse takings of groups who each had their own reasoning for their anti-militaristic stance ranging from veterans opposing based upon their produce or Civil Rights demonstrators who felt they were act to uphold the rights of the Vietnamese mint, whilst non needinessfully having the same themselves, domestic each(prenominal)y.What facilitated the exacerbation of the anti- contend movement was the greater access to uncensored reading in the extensive television coverage from Vietnam non stymieting that the right to freedom of nomenclature was in any case capitalised on by those in education who sought to bolster the importance of student acti vism, and their pressure group status.Others viewed the conflict as a fight against Vietnamese independence, or as intervention in a foreign civil war others opposed it because they felt it neglected direction and appeared to be potentially no-win devastation for a nation that was, and possibly in time is, the largest international influence. obtain ASource A, an extract from the book Four hours in My Lai by Michael Bilton (published in 1992), is a percentage that mainly focuses towards the military aspect of the war and the effects of the interest group had on real life soldiers this would be the case, assumption that this secondary informant is based upon an influential telling of events by some(a) individuals who were involved in the My Lai incident on 16 March, 1968. The U. S. soldiers who had been interviewed for this process a T. V. ocumentary had been produced prior to the semipublication of the book, in the belatedly 1980s may have been asked the questions qui te a few years after their involvement in the war, but this bears not much importee on what they say the vivid memories they would hold of that event would not leave for a prospicient time and so, by and large, would be true to an extent beyond doubt.The tooth root itself mentions that the increasing number of recruits scored so low on intelligence rankings that they wouldnt normally have been given a step forward in the regular U. S. ground forces during a peace-time period. It then goes on to mention how the tours of duty affected each soldier, with some dying in the first month of duty as this was passing likely. Due to the soldier rotation and their differing lengths of duty (some of the soldiers were wounded, so would not serve the same length as those they had arrived with, for instance) the inexperienced recruits were often polarised by the conditions they set about they were quite different to those they had probably been trained in, in the United States.The result o f this continuing spiral of poor strategy and younger and younger recruits et al. meant many an(prenominal) of the objectives which had been planned, at last failed in response to the effort which was existence put in low morale in existing, serving soldiers also played its resolve. A consequence of lose of planning and poor skill within soldiers trained, spontaneously affected those back home who saw lack of progress, especially at a time when the taxes were being increased by Johnson.With regards to the question, how utile is it for demonstrating why in that location was an anti-war movement it isnt that useful, since it doesnt mention any of the direct causes itself, instead implying various reasons for one explanation (i. e. giving reasons for the lack of progress which frustrated those in America). However, it does also give an impression that with the large numbers of deaths came great anger within communities who had lost a relative, a supporter or somebody else.This could be integrated into the logic behind the personal rationale that fell behind another reason why battalion exhibit against the Vietnam War they wanted to see an end to the bloodshed and unnecessary killing that engulfed the media reports throughout the U. S. Its advantages are also its downfall, ultimately the limitations of the source are great, as it doesnt con boldnessr the financial burdening on tax payers (or any other economic aspect), the Civil Rights movements, the disaster of the Great alliance programme, the suffering of the Vietnamese people shown in the media, or the media influence itself.So, therefore, it is useful for explaining the problems faced by the troops on the ground in Vietnam, who will have encountered people who werent responsible, nor mature enough, to make their own decisions and the horrific effects of the war on the Veterans something they took back from their tour of duty, exacerbating the anti-war movement as people flocked to prevent their relatives from being seriously maimed or killed. Source BSource B, a photograph contendn during a napalm attack on June 8, 1972, demonstrates the true extent to which the American bombings were taking their toll during the Vietnam War the children running representing the apparent acquitted victims that were being brutally murdered in raids that were deemed unacceptable by the mass of the American population. All of this contributed to the Credibility Gap which describes nearly any gap mingled with the reality of a situation and what politicians and government agencies make statements about.Once those who were reading the papers were shocked by the initial target of the bombing raids, anger would flexure into questions as they would seek who lied about the reality, perhaps even wondering what else the administration may not be revealing the full facts about. The deeper the credibility gap, the bigger the polarisation of people from the Vietnam War, who would now see it in a negative light and therefore would not be likely to support it, both financially and physically through public endorsements.As a primary source, its hard to find fault with the photograph it isnt likely to be redacted so it shows one side over another, and is also fairly neutral as it shows the after-effects of the American incursion, rather than something happening at that very moment. However, as the media was part of the continuing anti-war movement, this photo could in fact show only one incident that ever occurred but was highlighted for additional emphasis to their campaign given the accounts of citizens and U.S. soldiers, however, that is unlikely to be true. As its boilers suit point was intended to shock the readers in the U. S. A. , it is difficult not to find that this picture was as an asset to the movement given that it was taken by devote photographers, in this particular case, a Vietnamese one Nick it who would have wanted the war to be stopped, given it was hi s country that had been drawn into a long and bitter war.This isnt its only limitation however, as a photograph it only captures one event at one time, so by default it cant take into consideration other reasons for the anti-war movement. Saying that, it has a specific drive to underline that the government was lying about certain aspects of the war that it wanted to keep hidden this was released to make citizens aware of this fact. It is therefore useful for giving us some idea why there was a contra-militaristic viewpoint in the U.S. and why people were prepared to act upon that. Source C Source C, an extract from the publication of personal memoirs in 1982, gives us a personal perspective to an individual soldiers experience in the Vietnam War and McCarthy also reflects upon the intimacies of his encounter with the Vietcong. Whilst describing one event that occurred early on in his tenure as a rifleman, we see that as with many other U. S. oldiers he wanted to kill the Vietc ong upon hearing and seeing the effects of their second warfare tactics which meant that changes could be incurred by the Americans but often, there could be no retaliation given that the enemy couldnt be seen.McCarthy makes note of this saying that even in daylight it was hard to distinguish between those who were part of the Norths continuing campaign for the liberation of the South and those who were just normal peasants this resulted in to a greater extent deaths than had been initially projected.Due to the fact that often the enemy was not plain until it was too late, or in en masse confrontations, it was difficult to foresee a war that could be won by the Americans too many losses were sustained, whilst relatively modest amounts of VC combatants were being killed in fighting locations. Not only that, the VC also had foreign backing with the aid of China and the USSR helping with the funding and the strategical logistical movements of weapons. McCarthy mentions that we knew guys wives, mothers, fathers and kids suggesting that the impact of the deaths reached beyond the remit of the immediate family and affected other people, the soldiers themselves even whos stories of the deaths would return to their communities when they returned from their tour of duty all of which would be passed on to the public whos view of the war would possibly change from supporting to opposing based on what they hear, and see on the television and in the newspapers.However, there are other omissions from the source there is no particular relation to the failure of the Great Society programme or the struggle for Black Rights, for example. Nevertheless, that would hardly be compulsory in the personal memoirs of a soldier who has possibly died commenting on the situation as he felt it would not need to include any information which was not relevant to the experiences he had had.Due to there being no information to suggest other reasons for the anti-war movement, it co uld be considered not as useful for the purpose of investigating why but it does give us a personal reflection and wouldnt be biased for the simple fact that nothing was to gained for the author by writing this piece.Source DSource D, an extract from a newspaper piece by American journalist Richard Hamer in 1970, is a primary source revealing an extent to which the conflict was affecting those who were militarily involved the fact that often the Vietcong were invisible or out of range meant that often the troops became frustrated in their objectives and all too regularly lost sight of a war that could have been won if the South Vietnamese government convinced the peasants of the benefits of capitalism.Due to the complications with invisible attackers meant to a greater extent than and more lives were being lost and no retaliation could be given this sentiment is also present in Source C. This source runs along a central theme, however, and is understandably against the war and th e actions of some renegade soldiers who felt it necessary to commit atrocities like those at My Lai. At the time, this would have been a damaging piece of writing for its noticeable anti-American stance despite the writer being an American citizen.This in itself shows the deep degree of pacificism within the United States at the time, but this could, nevertheless, be part of a wider-ranging media campaign to prevent any further actions in the war due to other factors, perhaps the increase of taxes this would point that it is possible that Hamer wasnt anti-war based on the prospect, rather the inconvenience it cause him.The fact that this was released during the period of war means it is also linked to the credibility gap its exposure of American counter-tactics would almost certainly ensure the exacerbation of the anti-war sentiment and give another reason for people already desperate for relatives to return, to not believe what their government was saying.What we need to know h owever, is whether the information presented in this source is what Hamer actually saw with his own eyes, or whether it was a brief summarisation of stories he had collected from soldiers if the latter, its provenance could be affected, as soldiers influenced the reporters personal views. This source was also published one year after the My Lai incident has irreversibly affected most peoples views of the Vietnam War thinking what damage could be done to the reputation of the U. S. A, a country that had protected democracy only 20 years earlier in the Second World War this could then, be a piece catered towards their views, however, that is unlikely given the deep sense of conviction within the content of the source and the way in which he has pen the piece. This sense of betrayal by American soldiers extended to within the hearts of the communities across the U. S. who saw individuals committing acts which could not be seen as heroic in any respect.However, it is central to reme mber that most of the Vietcong were invisible to an extent they did use purposeful tactics that did have an effect most of the time soldiers did not who they were engaging with within the slurred forests and this did have devastating effects on those on the ground. Those injured in the attacks would return back to the U. S. sharing their stories and further affecting peoples views on the war that wouldnt lay off for (officially) 5 years after Source D was published.The use of the word one (in this context it is in reference to the collective American force) seems almost like a paradox the righteousness of that word compared with the conditions that were faced on the ground in Vietnam. As it focuses towards these aspects more than the other possible reasons for the anti-war movement, it may be seen as not that useful however, I would strongly discourage any sort of thinking along that line.It ascribes the particular tensions between the two rivalries on the ground as VC entered i nto guerrilla combat with the Americans, who hadnt been trained to a great level in that respect, and with the luck of hindsight suggests to us why there was an anti-war movement within the country its clear that the media used an en masse approach to their reporting of the Vietnam War, ensuring that the readers of their reports were to be influenced by their ideology on the subject whether it was because the papers were more left-leaning or were simply against the war because of the financial cost, for example, is of not much significance.Its main limitations are the fact that it doesnt mention some features of the war that turned people against it, such as the governments preference of that over the Great Society programme (being at a bad time, given that Black Rights had already suffered setbacks with the Martin Luther King assassination a few years earlier) and the drafting of poorer people from single out backgrounds, regardless of race. Source ESource E, a cartoon published by the satirical clip Punch in 1967, demonstrates the international view of the American involvement in Vietnam. Although it uses the failure of the key Great Society programme of the Johnson administration in its depiction of the costs of the Vietnam War, it does not discuss the effects of that failure or suggest any possible reasons for that (increased spending elsewhere, aside from the military, for instance).Another point is the fact that as Punch is a British magazine, it would be fabricated that they would favour the side that had helped them defeat the Nazi threat in the 1940s, but no, it could be interpreted that they instead believe that money is needlessly being boney on something that they themselves werent involved in perhaps because of the recovery that was still ongoing in the UK.In the cartoon, we can see President Johnson dismantling the US miserliness train (perhaps with connotations as a gravy train the sentiment prior to the war that was against the Communist threat, whereas now it wasnt) in favour or the war in Vietnam he had initiated with the conspiracy regarding the Gulf of Tonkin incident.The smoke billowing from the trains engine funnel reads Vietnam, backing up the British thought that money was needlessly being wasted in a dirty war. The source itself was published in 1967, not that long into the actual fighting phase of the war, but still after key events a great deal highlighted the fact that the programme Johnson had promised during his presidential re-election campaign of 1964 was failing.The effects of the unsuccessful plan meant that many of the potential conscriptees were turned against the prospect of being involved in the war their family would have already been affected by the change (as often those drafted were from impoverished backgrounds) but the deprivation would not only have an effect on them, it would also radically change those opinions held by the rest of their family. It would yet another reason to oppose t he war, especially considering taxes had already risen enough to concern the financial upbeat of most families.The limitations of the source are clear it, as many others, doesnt consider many of the aspects that made up the significant anti-war movement in the early mid-seventies the Civil Rights demonstrations (which is surprising given that those most affected by the collapse of the programme were mainly of an African-American ethnicity) or the media campaigns et al. Punch, as a satire magazine may not be the most reliable or sourcing though as a magazine dedicated to cynicism and making mockeries of political blunders, means with that purpose and the fact that evidently Punch were against the war, means the provenance of the source could be affected.On the other hand, it could be useful for explaining the views held by those who werent personally involved in the tragedies of death or affected by the charges made by the American government. Source F Source F, a partial transcr ipt from a seminar conducted by Robin Day in 1970, although addressing a British conference reflects upon the explanation for the sizeable increase in the anti-war attitude that had overran the initial support in the late 1960s.Day, a highly revered individual within the British media at that time, would have been eagerly listened to in the RUSI (a government think-tank studying naval and military science) seminar that took place during the latter stages of the Vietnam War Day gives what he thinks was the overwhelming reason that formed the basis for all the opposition against the war the repeated and consistent images of Vietnamese (and American) atrocity on the television.He believed that the repeated visualisation of what was really happening (given that during previous wars, colour television in real-time was not a reality) made images meet within the minds of the communities across America, who, on top of various misgivings they already had for the war would now act upon tha t it brought a sense of to reality a situation 10,000 miles out from home. Whilst saying that, he doesnt explicitly refer to this being the single factor in fact, it was the media campaign in its most general form it was the more uninhibited coverage as opposed to specific things that may have been seen.These images, as with the other sources that represent other media items released during the war, widened the credibility gap between the political mental home and those who it governed. Day had been reporting the Vietnam War since it had begun only a few years prior to this seminar and was knowledgeable on the topic of why and when the war really real in the full-scale conflict it did. This in turn means that the provenance is supported because we can rely upon this fact as meaning he would commiserate the complex motivations for particular events.This could, however, be his downfall as in that time he could have developed anti-war views based on what he had seen and been rep orting, that is unlikely though, given the general neutral tone of the source. The limitations to the source are obvious as some other causes for opposition included the returning wounded (and the much advertise deaths of) soldiers amongst others. Source G Source G, a 1989 look at adaptation from an autobiography of Ron Kovic, which contained extensive notes on his experiences in the Vietnam War a war which left Kovic paralysed for the majority of his body.In the film, the key points are * It is apparent that some of the authorities wanted to hide the veteran soldiers, due to the fact that they were a key component of the anti-war movement. * in that location were protests against the 1972 Miami Republican Convention, at which Nixon received his partys presidential nomination. * Some Republicans defended the war to an extent. * Often violent scenes when pro and anti war movements met.Some even mentioned that anti-war supporters were communists, because of their support for pacif ism and, although largely incorrect, left -wing socialism. Although Kovic was the inspiration for the story, Oliver Stone, the producer of the movie adaptation, was also someone known for his vehement opposition to the conflict in Vietnam. Through this film, Stone almost tries to change peoples perceptions of the war the dramatic re-enactments of events that happened and the exact quotes used in history re-quoted giving it a sense of reality.Kovic mentioned all the reasons why he was anti-war in the film extract, with the delegates in the background all shouting four more years as Nixon promised to withdraw the soldiers. Although produced some years after the end of the war, Stone still lacks the critical evaluation of both sides of the story, instead tending to focus on the anti-war movement almost completely but then, he would, he was an activist himself, trying to stop the deaths and serious maiming of further service personnel.The purpose of this film was to give the impression that the Americans were wrong to go to Vietnam in the first place (as Kovics character clearly says in the poor Vietnamese seeking freedom for hundreds of years) and that despite the intermittence between the end of the war and the time of the production, Stones views had not changed on the subject.In that context, and the fact that the film is much more dramatic than necessarily need be, it is easy to assume that this is a piece of biased film-making despite that, it is useful for one thing informing us of the thoughts of people who had experienced the full horrors of the conflict and the effect it had on them. It is also historically accurate as all the dates, places and people are all correct only the story itself is elaborated therefore it is reliable in some form.Referring back to the original question, How useful are the sources A to G for explaining why there was an anti-war movement in the United States during the late 1960s and early 1970s? I would respond by saying that some are more accurate than others in terms of their respective historical context, their individual purposes (some are cartoons, some are memoirs), and the reality that some are more reliable than others as they represent individual events on film or simply peoples thoughts on the war.In terms of service program, they have a collective price as when combined they allow a fuller picture of the war to be completed as opposed to thoughts garnered from one source. In some sources, the usefulness could be undermined by the purpose or the provenance of each source authors all have different views on what they write, but this can also be played to our advantage as even this in itself can represent the effect the conflict had on individual writers.Primary sources are not necessarily more beneficial as those that are produced as secondary sources, as often even in these cases, bias is still present often we forget that in secondary sources, the author has had the chance to evaluate many of the explanations for something of a long period of time before publishing their thoughts this can give us a better view of what really happened.

Co-curricular Essay

Co-curricular is one of the activities being neglected in most schools in the past years. Our school being one of them had for long been emphasizing heavily in class work. By doing this, we could not realize our talents which are very fundamental in making us whole. Activity carried on 4th March last-term made each member of this school to change his or her mind. We witnessed how students have extraordinary talents.Our school was among the top competing school in sports activities in this region. Sports has been one of the activity in school that that the administration has been overlooking. The school noted the need to change our strategies and came up with plans which leave give students a chance to realize their talents. The school used to conduct classes from eight in the morning to four in the evening.After this, students travel to evening group discussions and thereafter they went back again to their classes for evening preps. These activities made us busy throughout the day before retiring to bed. The school has fix up with a strategy that will ensure that students are trained both in class and in the co-curricular activities especially in sports. The Schools schedule is now flexible, as it will now allow students to get involved in these sports activities.Thanks to the students who participated in this event because due to their enthusiasm, passion and genius in sports the administration made a sensible consideration and made sure that it has allocated time for these activities. I am grateful for this action as it will serve as an example to other learning institutions. Sincerely, References Cooperating School Districts. (2010).

EKATO Organization Essay

A team is a formal work group whose members work internally with each other to achieve a common object glass. A self-managed team is a small group of employees responsible for an entire work process, improve their operation or product, plan their work, resolve day-after-day problems, and managethemselves. U. S companies including Ford Motor social club, Digital Equipment and Boeing report many positive benefits from their experience with self-managed teams including higher productivity, improved quality and lower turnover.Team teaching and EvolutionEXATO vision it self as a services organization involve in providing solutions for mixing problems, rather than just designing and manufacturing of mixing machines. EKATO objective was to design a flexible and optimized production facility at a realistic appeal, while creating an attractive environment to foster innovation. Therefore the bracing expression was designed to support a cell-based, self-managing culture.Before the change to self managing culture, an extensive consultation and participation programme was conducted. This was based around people, process, technological and architectural strategies. A planning groups consisting of both workers and representatives of the workers council was formed to discuss any affect on employees due to those changes.The plan is to squander 3 person groups. Wide-ranging internal teaching was made available to employees to support the new-managing, self-optimising approach in EKATO.With self managing teams approach brought good resultsThe new decentralised system amortized itself within the first 2 years operationThroughput clips were reduced by 50%Inventories fell by 50%Spare parts stores reduced by one-thirdMachine cost fellChanges to plans reduced by 40%Obtaining information and passing it on cost reduced due to its availability and the easy communicationDouble time work was eliminatedDue to the amount of coordination surrounded by that large no. of cells, the lodge reformed the cells into 8-9 persons instead of 3 allocated to three major manufacturing field of studys responsible for drives, shafts and impellers. Each manufacturing area has a leader who is responsible of that production group.ConclusionTeams can supply the competitive edge. Group pressures can have influence over individuals behavior. The basic philosophy is Entrusting employees with responsibility assures highest quality standards and low costs to the customers advantage.2. Evaluate the contribution that an effective HRM operation makes to the organization?maximizing the effectiveness of the human as restrains of an enterprise is critical. HRM strategies vary from one company to another but provide similar services to the organization. In EKATO, the HR is decentralized by making the department managers to be responsible for their staff finance and HR matters especially the appraisal and performance. HRM acknowledges a variety of activities, the key is deciding what st affing needs you have and whether to use independent contractors or hire employees to fill these needs. In EKATO hiring decision vital since staff compositiondetermines whether the firm has the necessary creativity skills and attitudes. EKATO maintains relationship with universities that specialised in process and involve this expertise on specific assignment. This open doors for universities students to work with the company after they finish their studies and be part of the organisation. Attracting new employees by rotating them through various sections of the company for few months including assembly to gain the hand on experience in the entire company and be multi arch(prenominal). Improving employees skills by providing extensive training programme to allow them to improve the productivity and have high quality performance. EKATO Team skills were improved through training before and after the move to the cell structure, to allow workers to be multi skilled and able to rotate roles to some extent. Coaching assisted individuals in personally adapting to working in teams on day-to day basis. Group members were trained in conflict resolution, problem solving, interpersonal relationship skills, team roles, group dynamics and decision making, as well as setting goals and priorities. The typically objective of the HR is to provide an atmosphere in which all employees can perform their jobs to the best of their abilities and creatively contribute to the organization. EKATO retains its people by providing interesting work environment. Working there is relatively challenging because employees need to keep up development by attending seminars and read to stay watercourse and keep up with fast technology. It is easier to make the job interesting for R&D staff than sales people. They motivate their employee by adjusting the reward system to include an individual bonus for works contribution and the group productivity which encourage workers to work as a team to ach ieve individual goals. Re-training some employees who resisting the new change of the company to be self managing and group process.In addition, human resources management includes 15 methods to improvecompetitive advantage.1. Working security organization gives employees a long-term contract.2. Carefully interview managers should be carefully choosing excellent employee.3. High salary the salary is higher than another competitor at least.4. Appropriate requital every month choose the excellent employee and give reward.5. Employee ownership provide stock of organization or share in project of profit.6. The salary concentrating settle the degree of the difference of the salary among employees.7. Participate in management let lower level employees join management.8. Term work and working design9. emblematic equality principle treat all employees equally.10. Internal upgrade through upgrade a lower level employee to higher position11. Measurement practicing disposal should measure employee attitude, different of the scheme and spirit of creation and ability of employee performance level.NotesIntroducing new technology such as expert system to help the company to manage and share solutions and knowledge, thereby reducing duplication.3. Discuss the extent to which leaders at EKATO have attempted to change the organisations culture? shade represents the unwritten feeling part of the organization. It refers to the set of values, beliefs, norms, attitudes, assumptions, and understandings shared out by all members of the organization. It also defines the basic organizational values and communicates to the new members joining the organization the even ways to think and act, and how things taught to be done.An understanding of organizational culture helps organizations respond and adapt to external environment by changing and solving internal problems.EKATO is a family owned enterprise. The founder Todtenhaupt was very technically oriented and has excellent relatio nship with his works and people in the chemical industry. The founder passed the organisation culture to his sons. exactly his sons changed the culture by bringing in an outsider Mr. Zeiler as CEO/President.The CEO, Mr. Zeiler believes that the leadership has to do with the personality style, values and assumptions. The CEO concentrated on the company internal matters and problems. With his sales background, he changed the company from role oriented i.e. bureaucratic to self managing culture. He focused on his workers by delegating responsibility to them and empowering skilled employees. He employ the trust and openness culture within the organisation by allowing staff to learn from mistakes. To prevent classical labour problem, the CEO implemented communication and sharing the information culture by having open discussion on the companys numbers, problems and goals. This is done by having two annual meetings between management and employees where the workers council and the CEO r eport to the staff. Beside that, top managers meet weekly and senior managers engage in cross-functional weekly problem solving meetings.Top management set the company plan and individual departments goals. Thesegoals are communicated to departments managers and then discussed within department staff. Senior mangers then meet quarterly to discuss the direction and review the scheme and areas of innovation. Each department manager is required to present results, costs and innovation capability. The outcome of these meetings are fed back to top management and then shared with staff.Hence, the spreading nature of culture will have an effect on organizational processes such as decision making, design of structure, group behaviour, work organization, and motive and job satisfaction. Management interest in organizational culture to improve performance and increase competition. It is developed and manifests itself in different ways in different organizations, therefore, it is not possibl e to say that one culture is better than the other. Hence, there is no such thing as an ideal culture, only an appropriate culture.

Foodborne Illness Short Answer Questions Essay

Salmonella1)What is the infectious means (Pathogen) that causes this infectious disease?The infectious agent (pathogen) that causes salmonella is called salmonella enteriditis. The bacteria is bigger than a virus but, is visible to the eye with the microscope. It is rod-shaped, gram negative, non-motile bacteria that does not form spores. It infects the cell, multiplies within it then, bursts the cell. Special effector protein factors are required for salmonella intestinal onset and the induction of fluid secretion and for inflammatory responses. There are about six names species names of it, salmonella enteritidis, and salmonella enteric which cause the human disease.2)How is this infectious agent transmitted through food or water?Salmonellosis is spread to people by ingestion of Salmonella bacteria that contaminate food.Salmonella is worldwide and can contaminate some any food type, but outbreaks of the disease have involved raw eggs, raw meat (ground beef and other poorly cooke d meats), egg products, fresh vegetables, cereal, pistachio tree nuts, tomatoes, and contaminated water. The most recent major outbreak in 2010 involved Salmonella-contaminated eggs from several U.S. producers that have caused the recall of over 500 million eggs. contaminant can come from animal or human feces that contact the food during its processing or harvesting. New data about types of food contamination.3)What is an simulation of a real life outbreak of this foodborne illness in the United States?

Theoretical Considerations Regarding Hazards And Risks Environmental Sciences Essay

The cognition of subjective and scientific abbreviate a chances is of the extreme effectance for carry oning feign and match judgment surveies, all(prenominal) bit faithful as land usage planning and exigency response planning. This whole mechanism signifi commodetly put forwards to the decree s sustainable emergence.For the overall comprehension of this issue, it is pas chirp relevant to specify the repeating arrive ats of this kick the bucket, viz. luck and lot.The peril constructTo get down with, a short ethimological abstract of the word chance is necessary. This term has been interpreted by the Gallic from Arabic, where it core dice game ( Mac and Petrea, 2002 ) . Harmonizing to the Longman Dictionary of Contemporary English, 2010, peril means both(prenominal)thing that may be unsafe, or cause accidents or jobs .In 1992, the United Nations International Decade for inherent Disaster Reduction secretariat published a multilingual lexicon so as to cle ar up and wholee the signifi deposeces of such footings. In this dictionary, jeopardy is defined as a baleful event or the adventure for a phenomenon with destructive potency to look in a individual part and in a given period of magazine publisher .Another definition is offered by the Grand Larousse Dictionary, volume V, cited by ZA?voianu and Dragomirescu in 1994 unintended and, by and large, unforeseeable interface between both or much causal series, whose common dealingss be purely defined in every minute and whose comparative independency trick merely be attributed to our ignorance and impotence .Scheidegger, 1994, cited by ArmaAY , 2003 defined jeopardy as the expose iodineself of rapid adaptation of a placement s province or stable conditions . In 1997 Grecu defined this construct as the possibility that a potentially annihilating phenomenon appears in a certain period of clip and in a certain part. In 1999 Octavia Bogdan and Elena Niculescu specify jeopardy as a random phenomenon on a big graduated table, un inevitable, a deficiency of finding between clip and infinite, a qualitative lap, a thres move over in the system s findment, downloading immense energy and doing up strike off, instability on the instinctive surroundal development s graduated table, in its manner towards a new province of equilibrium .In 2000 Ozunu defines the construct downstairs treatment as aza state of aff aureoles with the potency of an accident in 2001, BA?lteanu states that jeopardy is aza endangering event, stand foring the possibility for a potentially detrimental phenomenon to go on. Harmonizing to him, injury to people, goods and the environment occur.Alexander, 2000, cited by Thywissen, 2006, defines adventure as azan close geophysical event that keep do a catastrophe. asExtreme refers to an either positive or veto characteristic, legal injuryonizing to the tendency it is related to. The jeopardy s cardinal properties are location, cl ip, magnitude and frequence. Many utmost phenomena are perennial in clip and predictable in footings of location. We define game as an utmost event arising from the biosphere, lithosphere, hydrosphere or atmosphere. Mac, 2003, considers hazard as azthe reservoir of an utmost event with energy discharge in a certain minute and with a rather unforeseeable magnitude. In accompaniment, jeopardy posterior be referred to as aza phenomenological class that refers to headings and phenomena ( air multitudes, H2O, lithomass, biomass, people, twisters, epidemics, temblors, avalanches and so forth ) , to their actions ( inundations, clay flows, landslides, illness etc. ) every bit good as to their characteristics ( Mac, 2003 ) .In 2003, Cardona, cited by Thywissen, 2006, offers another definition of the term azthe possibility for a natural and unsafe event to go on in a certain clip and infinite . Generally, the construct of jeopardy is utilise to reference work to a latent danger or to an external hazard factor of a system or exposed capable.A jeopardy is composed of three elemental elements ( C. A. Ericson, 2005 ) 1. Dangerous belongings the basic kickoff of the danger that creates the jeopardy, i.e. a unsafe energy stock etc.2. Initiation mechanism the event that triggers or initiates the happening of the jeopardy, transforming the jeopardy from a inactive province to an active 1.3. Target and menace the individual, object, state of personal business vulnerable to damage ca utilize by the satisfyingisation of the jeopardy.These three elements compose the jeopardy trigon shown in protrude 2.1Figure 2.1 The jeopardy trigon ( C. A. Ericson, 2005 )The jeopardy trigon illustrates that all three above mentioned are interlinked. all in all three constituents are necessary in shape to organize a jeopardy. The remotion of one batch of the trigon way outs in the riddance of the jeopardy, because it terminate non take to an incident.By extenuating the in duction mechanism the chance of the incident to happen is reduced, and accordingly by extenuating an component of the unsafe belongings or home run and menace the badness of the incident will be reduced. These a priori facets and categorization prove to be great in any lowtaking refering jeopardy designation, extenuation, and hazard and strike appraisal.The basic construct of jeopardy organisation dope be summarized as follows ( C. A. Ericson, 2005 ) Hazards are deterministic entities and non a random 1s Hazards are constituted haply in systems Hazards are predictable and hence layabout be controlled and prevented Hazards can be set by their constituents Hazards will happen taking history of the constituents involved Hazards consequence in incidents.One of the term s most recent definitions is the 1 offered in 2009 by the International Strategy for Disaster Reduction secretariate a unsafe phenomenon, substance, human activity or status that may do loss of life sentence , suffer or other wellness impacts, belongings harm, loss of supports and services, societal and sparing break, or environmental harm. As it can be noticed from the above-named definitions, jeopardy is characterized through certain parametric quantities, such as geographical location, strength ( magnitude ) , frequence and its chance to go on. In some(prenominal) of these definitions, one can detect the accent lies upon entropy, deficiency of determinacy and capriciousness ( Mac 2003 ) . In order to measure these phenomena s possibility to go on, surveies refering their extreme values are considered. Furtherto a greater extent, in all these definitions the construct of jeopardy has a instead oppose intension, since it implies a certain grade of danger. Hazard can take the signifier of some remarkable phenomena or of some combines 1s, in footings of infinite and clip.Hazard appraisal purposes at identifying the likeliness of a belowtake jeopardy to go on in the hereafter, in a certain period of clip, its magnitude and impact country ( Pine, 2009 ) . For the appraisal of certain jeopardies such as inundations, temblors and vents there are good established, predefined methods. The consequences of these ratings are extremely relevant in footings of lucubrating land usage planning schemes and in implementing accident bar locomote.Hazard vs. hazardThe term jeopardy is closely related with the term hazard . Not few are the faces when confusion arises between the significances of these 2 constructs. This is why it is necessary to separate between them. Hazards are phenomena whose manifestations can barely be predicted and controlled. They gather in negative personal cause on commonwealth and on the environment. Imputing the characteristic of jeopardy to a natural or anthropic phenomenon is non conditioned by the production of material harm or by the being of victims, but by the potency of these effects to go on. ( Baldea, 2007 ) .Merely when that je opardy or phenomenon exceeds certain critical values, taking to material harm or casualties, does it go hazard. Therefore, a jeopardy is the menace that an event might go on and non the event itself. Should it impact a human community, to a certain extent, it becomes hazard.It moldiness be mentioned that the term hazard is attributed assorted significances, being used in different contexts. Its definitions have societal, economic, political and environmental values. In order to better understand its deductions, a short diachronic analysis is necessary.To get down with, the term under treatment was foremost used in the fifteenth light speed, when it referred to the trade s fiscal danger ( Proske, 2008 ) . Initially, this construct was associated with economic activities, being so used in the theory of chance and gaming. In the nineteenth century it is integrated in economic system, experiential doctrine and determination theory, whereas in the twentieth century it was used as poli tical term in atomic engineering in order to gauge the distributor plosive consonant of security that was acceptable for people.Until the 8th decennary of the old century constructs such as hazard, jeopardy and hazard oversight were associated with natural phenomena. Hazard and natural or anthropic jeopardies analysis became an interdisciplinary kingdom of report with its special nomenclature merely in the last 30 old ages.The Longman Dictionary for Contemporary English, 2010, defines hazard as the possibility that something bad, unpleasant, or unsafe may go on .In 2007 ISDR defines hazard as the combination of the chance of an event and its negative effects . In 1999 Octavia Bogdan and Elena Niculescu define hazard as the active chance or possibility for a phenomenon to go on . This event is someway expected and has negative reverberations, in response to which world can merely be inactive.Another definition is offered by Ozunu in 2000 the chance that the existing jeop ardy turns into an accident .Alwang, 2001, cited by Thywissen, 2006, defines hazard as the possible distribution of some known or unknown events. These are characterized by magnitude, frequence, continuance and history .In the same twelvemonth, Peduzzi, cited by Brauch, 2005, considers risk aza step of possible losingss generated by a jeopardy of a certain magnitude, produced in a certain part and period of clip .It must be stated that natural events can turn into social hazards when they surpass the immediate capacity of being counteracted or absorbed. They are, in most of the instances, utmost events. An utmost natural event is any event or series of events that shows a f lee sideting or durable fluctuation as compared to its common values. ( White, cited by ArmaAY , 2003 )The widely accepted definition of hazard as the merchandise between the chance for an event to go on and the negative effects it may hold is expressed as followsR= F x C ( Eq. 2.1 )whereR- hazard ( losses/un it of clip ) , F- frequence of happening ( no. of events/unit of clip ) , C- effects ( losses/event ) .Hazard can besides be defined as the chance of human exposure, of semisynthetic goods and of the environment to the action of a jeopardy of a certain magnitude and their exposure towards it ( BA?lteanu, 2005 ) .For Petrea, 2009, hazard is the possibility that some negative effects for human communities or losingss ( human lives, hurts, diminished agencies of subsistence, goods, harm of the environmental constituents ) appear as an fundamental interaction between natural or anthorpic jeopardies and territorial exposure .This manner associates two distinguishable elements, viz. the jeopardy and the receiving system ( in most of the instances, a certain population ) .In most of the instances, the undermentioned expression is usedR= Hazard x Vulnerability ( Eq. 2.2 )This underlines the relation between an event and its effects. In a certain country, the hazard is comparatively un changing. What differs is community exposure, in footings of its reaction to menaces or its stratum of readiness to confront them. Harmonizing to the above-named expression, hazard may match to a high-frequency jeopardy and a low exposure or to a low-frequency jeopardy and high exposure. The disadvantage of this expression is that it does non see the population denseness, i.e. its exposure to hazard. Mitchell, 1990, cited by Brauch, 2005, completes this expression, sing jeopardy as a map of hazard, exposure, exposure and responseHazard= degree Fahrenheit ( hazard ten exposure x exposure x response ) ( Eq. 2.3 )wherehazard the chance that negative effects appear,exposure the size and characteristics of the open population,exposure the potency of harm to bring forth and response refers to the compel steps for hazard lower.Another definition is given by Ozunu and Anghel in 2007R = F x C x V ( Eq. 2.4 )whereR hazard F- frequence C effects V- exposure ( ) .The harm produced as a consequence of a catastrophe is really the consequence of the interaction among physical environmental factors ( clime, H2O, landscape etc. ) , population ( societal categories, civilization etc. ) and the built environment ( edifices, substructure etc. ) ( Mileti, 1999 ) . Therefore, jeopardy can be considered the pre-disaster state of affairs, when hazard does non look. A phenomenon s development has three phases, more precisely the jeopardy one, when merely hazard appears, the hazard phase, when jeopardy can impact human guild and, eventually, the catastrophe. ( Alexander, 1993 )In decision we can province that there are two types of hazards, viz. an acceptable one, where losingss are tolerable for the population and catastrophe, when losingss can non be tolerated by the local community.Categorization of jeopardies and hazardsAs antecedently mentioned, jeopardies and hazards are defined and characterized in multiple ways. In this chapter, a categorization is presented harmoniz ing to the most relevant features beginning, effects, frequence, bear upon surface, etc.Categorization after beginningThe categorization of jeopardies harmonizing to their beginning is presented in table 2.1Table 2.1 Categorization after beginning ( BA?lteanu, 2005 ) intrinsic jeopardiesEndogenousVolcanic eruptions, seismicityExogenousClimaticCyclones, twister, storms, lightning, hail, hoar, drouth, etc.geomorphologicMass supplanting, erodingHydrologicFlash-floodsOceanographicRise of planetal ocean, El NinoBiologicalEpidemics, viruses, insect invasionsAnthropogenetic jeopardiesTechnologicalIndustrial, agricultural, transport accidentsHuman( Benedek, 2002 )SocialPoverty, unemployment, urbanisation, life styleMedicalInfectious, viral, chronic, degenerative diseasesDemographicEmigration, population growing, aging of populationPoliticalTerritorial, political differences2.3.2 classification harmonizing to the manifestation mannerThe categorization of jeopardies harmonizing to their m anifestation manner is presented in table 2.2 ( GoA?iu and Surdeanu, 2008 ) Table 2.2 Hazards categorization harmonizing to their manifestationViolent jeopardies temblors vents severe storms, twister, etc. local storms with hail etc. catastrophic landslides, avalanchesHazards with progressive development Mediterranean disturbances ( Mediterranean cyclones with retrograde development )Hazards with slow development drouth severe drouth radiation and vaporization mists2.3.3 Categorization after continuanceHazards can besides be classified harmonizing to their temporal development.

In order to develop efficient schemes for measuring hazards and impact, the NATECH ( natural jeopardies which trigger technological accidents ) rule is necessary to be considered when measuring either of the two above mentioned types of jeopardy. Current EU ordinances in the field of hazard appraisal and catastrophe direction ( European Commission, 2010 ) stress the necessity of a multi-risk and multi-hazard attack in all natural and anthropogenetic jeopardy and hazard surveies.Therefore, there is a turning involvement in the scientific community and among stakeholders sing natural jeopardies which trigger technological accidents ( NATECHs ) . NATECHs have important negative effects on human wellness, the environment and the economic system. The addition in the figure of such events is closely linked with the exponential technological development of the early(prenominal) decennaries, due to the variegation of engineerings, the turning figure of personal exposed, and the substances used in the technological single-valued functions. The effects of NATECH events have become more terrible at heart this timeframe chiefly due to the exposure of the population life rise these installations.Given these facts, there is an pressing demand for raising consciousness about bar and readiness steps refering these high effect low chance events ( Cruz and Okada, 2008 ) . Due to the obscureness of NATECH events, their word picture is instead hard, and many NATECHs are analyzed and assessed as separate natural or technological events ( Embelton and Embelton-Hamann, 1997 ) . One needs to take into history that the effects of such an event differ in tortuousn ess from the effects of the two events taken individually ( Cruz and Krausmann, 2008 ) . Therefore, there is a demand for scientific research on the interactions and dealingss between natural jeopardies and technological accidents. Addressing NATECHs requires a combined attempt of industrial and technological hazard direction specializers working together with specializers concentrating on natural jeopardy probes.The specific features of a NATECH event ( Domino impacts, multiple effects ) need specific steps for the bar, response and recovery after such an event. An integrated hazard and impact direction scheme must include the possibility of NATECHs to happen, and necessitate specialised planning for extenuation, response, and recovery ( Ozunu et al. , 2011 )The Activities Report On the collaborationism Agreement between the International Strategy for Disaster Reduction of the United Nations and the Directorate General adjunction Research Center of the European Commission propose s a scheme for the extenuation of NATECH events byi persistence hazard direction specifically turn toing the possible impacts of natural jeopardies on technological installings. Additional hazard direction processs ( Figure 2.2 ) in order to cut down the exposure to NATECHs the usage of excess natural rubber systems, natural jeopardy resistant designs, guidelines to inform intentness about NATECH planning, and strategic arrangement of equivocal substances in spite of appearance a unit.Figure 2.2 Catastrophe Management processs ( Torok et al. , 2009 )Efficient Emergency planning, including bar and extenuation, and response planning for NATECHs at all degrees of political science. The purpose of the Risk Analysis procedure is to cut down uncertainnesss by increasing guard duty degrees by developing more efficient Emergency Plans, offering immediate determinations, detailed, accurate and steady instruction manual ( ( Torok et al. , 2009 ) i Land usage planning, as an of import tool for setting-up insularity margins in order to nurse occupants populating near risky installations. ( Christou et al.,2006 quoted by Torok et Al. 2011c ) . Article 13 of the SEVESO III Directive ( Directive 2012/18/EU ) provinces that Member States shall guarantee that the aims of forestalling major accidents and restricting the effects of such accidents for human wellness and the environment are taken into history in their land-use policies or other relevant policies Information and instruction of the populace, authorities bureaus and all stakeholders involved in exigency direction, including decision-makers.i Public engagement in NATECH hazard decrease planning, in order to better understand the perceptual experience of the degree of the NATECH hazard and the degree at which this hazard is considered acceptable ( Ozunu et al. , 2011 )Qualitative and quantitative methods for placing jeopardies and measuring hazardsA systematic designation of possible environmental impacts atm ospheric pollutants have, every bit good as a strict analysis of their magnitude is required. The intent of such a procedure can be divided in two major issues, on one hand to bring forth quantitatively accurate appraisal of peculiar hazard and a comprehensive controversy of possible environmental impacts, and on the other manus produce a principle for doing public constitution determinations that is both good reasoned, and recognized as legitimate and acceptable by the socio-economical factors.A complex environmental impact appraisal ( EIA ) and hazard appraisal ( RA ) methodological analysis requires assorted sets of informations about beginning footings, emanations, imissions, exposure, local weather forecasting, terrain informations etc.. Most of the air scattering abstractive count ons have been true for the anticipation of lee concentration of air pollutants and for the appraisal of short-run and medium-term effects of these pollutants. The eccentric of consequences obt ained utilizing these patterning systems depend largely on the versatility and quality of input informations and the right plump of the theoretical account ( Torok et al. , 2011a ) .In instance of EIA surveies, the medium-term effects appraisal requires emanation and meteorological informations for several months in order to obtain a realistic distribution of the largely colly countries. The consequence of the complex terrain on the air motion in the commixture bed is important. Therefore the meteorological information for the modeling period should be calculated sing the air flow above the complex terrain.For RA, the appraisal of immediate effects of ague exposure requires on-site informations for a short clip period. These informations sets must incorporate information about emitted substances ( type and concentration ) every bit good as real-time local meteorological informations, which along with terrain informations can be used in a rapid environmental and risk appraisal, which is a valuable tool for on-site exigency planning in instance of accidental or deliberated releases of toxic substances in the ambiance ( Torok et al. , 2011a ) .In the field of hazard analysis and hazard appraisal there are differences of sentiment sing the usage of qualitative or quantitative hazard analysis methods. The qualitative-quantitative factor is the basic belongings of jeopardies analyses methods. Most of the analysis methods are developed in order to shopping centre jeopardies and to find the hazard of that jeopardy turning into an accident.For finding the accident hazard of the identified jeopardy, a methodological analysis for the word picture of chance and magnitude parametric quantities must be used. There were developed both qualitative and quantitative methods, which are successfully used, each methods holding its specific advantages and disadvantages ( Torok et al. , 2011a ) .Qualitative methods used in jeopardy analysisA qualitative analysis implies the us age of qualitative standards, utilizing different classs for parametric quantities separation, with qualitative definition which set up the graduated table for each class. Besides, qualitative determinations are made, based on the field experience, in order to delegate elements into classs. This attack is subjective, but it allows a higher generalisation grade, being less restrictive.2.5.1.1 title of jeopardiesThe designation of technological jeopardies is the basic measure in hazard appraisal procedure. Hazards appear in the industry all the clip, due to the procedure and runing conditions of the installings and the physical, chemical and toxicological belongingss of the substances used in these procedures. This is why it is extremely of import to place the substances risky belongingss and the operating conditions that put at hazard these procedures, the series of events that may take to the offspring of a jeopardy.In order to develop an in-depth survey of jeopardies and hazard a nalysis, the risky belongingss of the substances must be identified and assessed in order to find conditions or non they pose a jeopardy to human life, the environment of the technological procedure.From a qualitative point of position this can be achieved utilizing checklists. A comprehensive checklist used in the appraisal of jeopardies and hazards posed by substances is presented in table 2.5Table 2.5 Hazardous belongingss of substances- Checklist ( Hyatt, 2003 )TypePropertyGeneral belongingssMolecular constructionFreezing pointMelting pointVapour force per unit areaBoiling temperatureCritical force per unit areaCritical temperatureCritical volumeDensitySpecific heatViscosityThermal conductionFluid densenessLatent vaporisation heatDielectric in unsettledElectric conductionFlammability salvo/ Flammability leapExplosion thresholdAuto ignition temperatureMinimal ignition energyOverheatingCorrosionCorrosive for building stuffsIncompatibility with other stuffsPolymerizationDecompos itionFeatures of polymerisationFeatures of decompositionFeatures of hydrolysisImpuritiesImpurities in equipment stuffsImpurities in substanceChemical reactions, detonationsHeat of formationHeat of decompositionCombustion heatThermal constancyResistance to impactPotential energy jeopardiesToxicityExposure bounds IDLH ERPG1-2-3 AEGL 1-2-3 LC50 and LD50Exposure effects ( inspiration, consumption, tegument and oculus make )Effectss of long-run exposure with little sumsWarning bounds ( odor threshold )RadiationRadiation boundsI , I? , I? atomsMaterial toxicityIt must be stated that stuff toxicity depends on a series of physical and chemical factors, in the type of contact and on the interaction of substances with beings. The ways in which this penetrates the native structure are assorted, viz. unwritten ( through the oral cavity, in the tummy ) , epidermal ( toxicity enters the tegument ) or by agencies of inspiration ( through the respiratory system ) .The harmful belongingss of risky substances can be divided into the undermentioned classs ( Ozunu and Anghel, 2007 ) acute toxicity ( really toxic, toxic, harmful, annoying )specific belongingss ( allergic, carcinogenic, with consequence on reproduction or familial consequence )with harmful impact on the environmentWhereas the first-year two classs mentioned supra have direct inauspicious consequence on wellness, the last one acts indirectly on human existences by damaging the environment.The harmful actions start when little sums of substances appear in the organic structure should larger sums appear, they can take to one s decease. The most normally used indexs to find substance toxicity are ( Torok et al. , 2011c ) medium deadly dose- LD50 is the dosage at which half of the experimental population of animate beings ( or worlds, should human deceases be registered ) dice. LD50 index at consumption and at the skin degree is shown in milligram ( mgs ) of substance per kg of animate being organic structure, taking into history a individual disposal.the medium deadly concentration LC50 concentration for inspiration is measured in mgs of substance per fifty of air breathed or in volumetric parts per million -ppm ( exposure clip differs depending on substance toxicity )the immediate unsafe concentration for life and wellness IDLH is inspiration with irreversible effects on wellnessThese bounds of concentration are used as indexs in both the US and the EU statute law ( NIOSH, 2012 ) .The bounds of toxicity for a series of substances are set in the Dangerous Substances Directive 67/548/ europium. They are grouped harmonizing to some classs presented below. Each type of danger has a hazard phrase ( Rphrase ) consisting of a figure and of the appropriate hazard description ( Ozunu and Anghel, 2007 Directive 67/548/ EEC ) .Table 2.6 LD50 ( unwritten )ClassLD50( mg/kg )SymbolRphraseVery toxic& lt 25T+R26, R27, R28Toxic25 200ThymineR23, R24, R25Harmful200 2000XnR20, R21, R25The rate o f flow thesis focal points on two major jeopardies, natural 1s, with a instance survey on volcanic ash, and anthropogenetic 1s, with instance surveies on S dioxide ( SO2 ) .Sing volcanic ash, the most serious jeopardies can be associated with itscaustic belongingss on stuffs, i.e. aircraft engines, windscreens, etc. ,runing point, the volcanic ash runing inside the turbine due to the high temperatures, and so solidifies in the ice chest parts of the engine s.denseness, the denseness of volcanic ash is comparatively high, wry ash being up to 5 times, wet ash about 20 times denser than snow. This fact represents a major jeopardy to edifices when ash accumulates on the roofs in sufficient measures, taking to prostrations.In the instance of SO2, the major jeopardies are associated withQuantitative methods used in hazard appraisalQuantitative analysis implies the usage of numerical or quantitative informations and provides quantitative consequences. This attack is more nonsubjective and more precise. It must be mentioned that the quantitative consequences can be extremely affected by the preciseness and cogency of the input parametric quantities. Therefore, the quantitative consequences within the hazard analyses should non be taken into consideration as exact Numberss, but as estimations, with a variable graduated table depending on informations quality ( Torok, 2010 ) .2.4.2.1. ModelingThe representation of world through mold is extremely relevant, since it offers one the possibility to analyze and analyze systems in footings of mathematics and technology. It must be mentioned that a system consists of a set of elements that interact with one another within some bounds. Furthermore, this system has a specific behavior. These bounds are really the 1s that separate the system from the other 1s. These theoretical accounts can be divided into two classs, viz. physical and abstract ( fanciful or numerical ) theoretical accounts.With respect to the physical theoretica l accounts, they describe the system from a physical point of position, utilizing the physical Torahs that apply upon the system under treatment.The numeric theoretical account of a system describes it in footings of mathematical equations, utilizing simplifying hypotheses.Abstractization works in both ways, i.e. from object to its representation ( theoretical account ) and so back to world. Still, it must be stated that this theoretical account does non picture world all the clip it tries to be as closer to it as possible. The more complex a system is, the more complicated the theoretical account becomes. In this context, the purpose of patterning systems and processes utilizing the computing elevator car is to make a theoretical account that contains a description realistic plenty for the given application.The basic stairss for the accomplishment of a mathematical theoretical account are as follows ( Savii and Savii, 2000 ) job designation and the pick of variablesbuilding of mathematical dealingss among variables utilizing simplifying premisesthe purchase of information sing the size, importance and interrelatednesss for each variable under treatmentthe choice of input signals parametric quantitiesconstitution of province variablesproof of premises and dealingssutilizing the right theoretical account harmonizing to the state of affairs.2.4.2.2. computer simulationWith the development of information engineering and computation equipment, the scrutiny of theoretical accounts utilizing simulations has become possible. air allows proving those systems functionality theoretical accounts that have yet to be or are presently in design stage. Simulation is the lone possibility of analyzing the dynamic behavior of such a theoretical account. Discrete simulation, utilizing theoretical accounts of different systems, is of great aid for projecting production systems, where issues of optimisation appear ( Savii and Savii, 2000 ) .In the present thesis we focus chiefly on the mathematical mold of the gas pollutants scattering in the ambiance.Beginning theoretical accounts are used to specify the quantitative emanation scenario of substances by gauging their flow rate, the scattering of substance after release. scattering theoretical accounts turn the end products from beginning theoretical accounts into isoconcentration curves specifying concentration countries and cipher the development of concentration in clip.The mass conveyance of molecular- home base fluid occurs through diffusion, with a changeless diffusion velocity throughout its motion. However, wonky scattering is a procedure different from molecular diffusion, since the mass conveyance occurs at assorted scale lengths of the disruptive motion. Disruptive scattering is much more efficient than molecular diffusion. The scattering rate is non changeless it depends on the size of the whirl and of that of the cloud of spread pollutant. These whirls can be of different sizes on a big graduated table, they determine the motion of the pollutant cloud, whereas on a little graduated table they contribute to its dilution. The energy and size of these whirls determine gas plumes scattering. Their continuance, length and strength are the chief factors that influence this procedure.The mathematical mold of gas pollutants in the ambiance is based on equations of mass, energy and impulse preservation. Such an equation must be established for each pollutant. It represents the fluctuation of atoms denseness in clip and infinite. From these equations one can acquire a complex system of equations that can be solved by agencies of numerical methods, obtaining the quick behavior of concentration in clip and infinite.A literature reappraisal reveals two chief methods used for picturing the behavior of pollutants released into the ambiance, viz. the Eulerian sanctimoniousness and the Lagrangian 1. Both methods are used to depict the statistical belongingss of pollutant con centration.The Eulerian formalism starts from ciphering fluid speeds in the ten, Y and omega waies, measured in fixed points in the fluid under treatment. Input information is comparatively easy to obtain from the measuring or mold of discharges, but work outing the mathematical equations system can be really complex, ensuing in inaccurate solutions. diffusion coefficients can be retrieved utilizing the Pasquill-Gifford graduated table ( Pasquill, 1961 ) . After this, the imission map for a beginning point and meteoric scenario can be developed.The Lagrangian formalism uses the statistical belongingss of some fluid atoms that move passively, freely. As compared to the Eulerian formalism, the mathematical equations system is easier to work out, therefore it is computationally really efficient, and merely the fraction of the sphere really involved in the scattering is simulated. Disruptive procedures are included in the theoretical account in a more natural manner, and there is no im portant numerical diffusion ( Stohl et al. , 2005 ) .Still, the method s pertinence is moderate by the troubles encountered when finding the statistics of fluid atoms. The Lagrangian formalism is applicable upon long-distance scatterings, when the complex topography influences the flow of air-pollutant multitudes.Although the scattering procedure is a typically Lagrangian one, about all information available refering the ambiance are based on Eulerian measurings. Therefore, a relation between the Eulerian belongingss and the Lagrangian 1s is ( widely ) accepted ( Sandu et al. , 2004 ) .
