Can Technology Replace Teachers Essay Example for Free

Can Technology Replace Teachers Essay TV, computers have fully integrated into urban life in many spheres like education, entertainment, and commerce, and therefore, some people consider that the technology such as multimedia teaching would replace teachers in class. I would say this does not sound very convincing because the superiority of the teachers are obvious. The first and most apparent advantage that face-to-face conversation is a vital ability for the environment of the social working is clear. Teachers give students direction to have a good grasp to work in the team or respect each other. It is possible for one to have a video communication with teacher to achieve that, however, the meaning of much of what we say depends on our body language and tone of voice which can not be transmitted by the computers. The interaction between teachers arid students is the core of teaching process. Additionally, it is generally thought that multimedia always connects with Internet which is a double-edged sword. The Internet with innumerable news sources about curriculum let us make the paradox of choice. For instance, we downland a mass of materials for TOEFL tests but do not know which one to start. Teachers play significant roles to guide our study, and they can tell us where we begin with, what we should do, and which reference we should choose, hence their proposal always make a huge difference especially in a brand new discipline. As a facilitator ,teacher can make us learn efficiency. Whats more, students,with low self-control, also easier to indulge in bad or rather faulty information and act on it. Teachers also play significant roles in supervising students. In conclusion, the computer has been widely used in class,it cannot replace the role of teachers who impersonated an essential part of modern education. Nevertheless,multimedia teaching facilitates our education like PPT teaching which can avoid the chalk dust. Teachers can use this trait to mend and consummate our education.

Managing financial resources and decisions JS and CO

Managing financial resources and decisions JS and CO JS and co is a medium sized retailer formed by two partners, James and Sainsbury, who are running it in the UK since 1869. The retailer specializes in quality food products but it sells other non-food products as well. This company got very good success in the market from the past three years. During this discussion we are going to discuss about this company sources of finance, finance as a source, financial decisions, and financial performance. The broad view of this company in our discussion: P1 (sources of Finance) P2 (Finance as a resource) P3 (Financial decisions) P4 (Financial performance) P1 (SOURCES OF FINANCE) IDENTIFY THE SOURCES OF FINANCE AVAILABLE TO THE BUSINESS When a company is growing rapidly, for example when contemplating investment in capital equipment, its current financial resources may be inadequate. Few growing companies are able to finance their expansion plans from cash flow alone. They will therefore need to consider raising finance from other external sources. In addition, managers who are looking to buy-in to a business or buy-out a business from its owners may not have the resources to acquire the company. They will need to raise finance to achieve their objectives. There are a number of potential sources of finance to meet the needs of a growing business Existing shareholders and directors funds Business angels Clearing banks (overdrafts, short or medium term loans) Factoring and invoice discounting Hire purchase and leasing Venture capital A key consideration in choosing the source of new business finance is to strike a balance between equity and debt to ensure the funding structure suits the business. The main differences between borrowed money (debt) and equity are that bankers request interest payments and capital repayments, and the borrowed money is usually secured on business assets or the personal assets of shareholders and/or directors. A bank also has the power to place a business into administration or bankruptcy if it defaults on debt interest or repayments or its prospects decline. ASSESSING THE IMPLICATIONS OF DIFFERENT SOURCES. Financial institutions that transcend national boundaries and engage in such activities as extensive inter bank contracts, over-the-counter derivatives contracts, quit, bond, and syndicated loan issuance, and trading activities globally has led to stronger interconnections, innovation, and growth. While tighter interdependencies can increase the efficiency of the global financial system by smoothing credit allocation and risk diversification, they have also increased the potential for cross-market and cross-border disruptions to spread swiftly. In addition, financial innovations have enabled risk transfers that were not fully recognized by financial regulators and institutions themselves, and have complicated the assessment of counterparty risk, risk management, and policy responses. Although linkages across institutions have traditionally focused on solvency concerns, the current crisis reminds us of the relevance of liquidity spillovers, specifically that (1) Interconnectedness means difficulties in rolling over liabilities may spill over to the financial system as a whole; and that (2) Rollover risk associated with short-term liabilities is present not only in the banking sector but, equally importantly, in the nonblank financial sector. Thus, it is essential to improve our understanding and monitoring of direct and indirect financial systemic linkages, including by strengthening techniques to assess systemic link-ages, and thereby contribute to making systemic-focused supervision feasible. Four complementary approaches to assess financial sector systemic linkages and focuses on this definition of systemic risk: 2 The network approach The co-risk model The distress dependence matrix The default intensity model CHOOSING THE APPROPRIATE SOURCE OF FINANCE FOR THE BUSINESS. There are a number of ways of raising finance for a business. The type of finance chosen depends on the nature of the business. Large organizations are able to use a wider variety of finance sources than are smaller ones. Savings are an obvious way of putting money into a business. A small business can also borrow from families and friends. In contrast, companies raise finance by issuing shares. Large companies often have thousands of different shareholders. To gain extra finance a business can take out a loan from a bank or other financial institution. A loan is a sum of money lent for a given period of time. Repayment is made with interest. The lender of money needs to know all the business opportunities and risks involved and will therefore want to see a detailed business plan. The lender may also want some form of security should the business run into financial difficulty, and may therefore prefer to provide a secured loan. Another way of raising short-term finance is through an overdraft facility with a bank. The borrower is given permission to take out more from their account than they have put in. The bank fixes a maximum limit for the overdraft. Interest is charged on the overdraft daily. Businesses may also qualify for grants. Government and private funds are sometimes made available to businesses that meet certain conditions. For example, grants and loans may be available to firms setting up in rural areas or where there is high unemployment. Out comes: By this module I understood the different long term and short term sources of finance with the implications of choice of one source over the other and any advantages and disadvantages of sources different sources of finance. P2 (FINANCE AS A RESOURCE) ASSESS AND COMPARE THE COSTS OF ABOVE MENTIONED SOURCES OF FINANCE. A company might raise new funds from the following sources: The capital markets: i) New share issues, for example, by companies acquiring a stock market listing for the first time ii) Rights issues  · Loan stock  · Retained earnings  · Bank borrowing  · Government sources  · Business expansion scheme funds  · Venture capital  · Franchising. Ordinary (equity) shares Ordinary shares are issued to the owners of a company. They have a nominal or face value, typically of $1 or 50 cents. The market value of a quoted companys shares bears no relationship to their nominal value, except that when ordinary shares are issued for cash, the issue price must be equal to or be more than the nominal value of the shares. Deferred ordinary shares Are a form of ordinary shares, which are entitled to a dividend only after a certain date or if profits rise above a certain amount. Voting rights might also differ from those attached to other ordinary shares. Ordinary shareholders put funds into their company: a) By paying for a new issue of shares b) through retained profits. New shares issues A company seeking to obtain additional equity funds may be: a) An unquoted company wishing to obtain a Stock Exchange quotation b) An unquoted company wishing to issue new shares, but without obtaining a Stock Exchange quotation c) A company which is already listed on the Stock Exchange wishing to issue additional new shares. EXPLAINING THE IMPORTANCE OF FINANCIAL PLANNING Financial planning it is a process which presents before an individual, organization or even a country, the current financial position and the adjustments in the spending pattern, in order to meet the goals. Importance of Financial Planning It is important to plan finances in order to reap long term benefits through the assets in hand. The investments that one makes are structured properly and managed by professionals through financial planning. Every decision regarding our finances can be monitored if a proper plan is devised in advance. The following points explain why financial planning is important. Cash Flow: Financial planning helps in increasing cash flow as well as monitoring the spending pattern. The cash flow is increased by undertaking measures such as tax planning, prudent spending and careful budgeting. Capital: A strong capital base can be built with the help of efficient financial planning. Thus, one can think about investments and thereby improve his financial position. Income: It is possible to manage income effectively through planning. Managing income helps in segregating it into tax payments, other monthly expenditures and savings. Family Security: Financial planning is necessary from the point of view of family security. The various policies available in the market serve the purpose of financially securing the family. Investment: A proper financial plan that considers the income and expenditure of a person helps in choosing the right investment policy. It enables the person to reach the set goals. DESCRIBE THE INFORMATION NEEDS OF DIFFERENT DECISION MAKERS. Commonly used indicators such as the gross national product (GNP) and measurements of individual resource or pollution flows do not provide adequate indications of sustainability. Methods for assessing interactions between different sectoral environmental, demographic, social and developmental parameters are not sufficiently developed or applied. Indicators of sustainable development need to be developed to provide solid bases for decision-making at all levels and to contribute to a self-regulating sustainability of integrated environment and development systems. (a) To achieve more cost-effective and relevant data collection and assessment by better identification of users, in both the public and private sectors, and of their information needs at the local, provincial, national and international levels; (b) To strengthen local, provincial, national and international capacity to collect and use multicultural information in decision-making processes and to enhance capacities to collect and analyze data and information for decision-making, particularly in developing countries; (c) To develop or strengthen local, provincial, national and international means of ensuring that planning for sustainable development in all sectors is based on timely, reliable and usable information; (d) To make relevant information accessible in the form and at the time required to facilitate its use. DESCRIBE THE IMPACT OF FINANCE ON THE FINANCIAL STATEMENTS. Financial statements (or financial reports) are formal records of the financial activities of a business, person, or other entity. All the relevant financial information of a business enterprise presented in a structured manner and in a form easy to understand, is called the financial statements. There are four basic financial statements: Balance sheet: also referred to as statement of financial position or condition, reports on a companys assets, liabilities, and Ownership equity at a given point in time. Income statement: also referred to as Profit and Loss statement (or a PL), reports on a companys income, expenses, and profits over a period of time. Profit Loss account provide information on the operation of the enterprise. These include sale and the various expenses incurred during the processing state. Statement of retained earnings: explains the changes in a companys retained earnings over the reporting period. Statement of cash flows: reports on a companys cash flow activities, particularly its operating, investing and financing activities. For large corporations, these statements are often complex and may include an extensive set of notes to the financial statements and management discussion and analysis. The notes typically describe each item on the balance sheet, income statement and cash flow statement in further detail. Notes to financial statements are considered an integral part of the financial statements. Outcome: By this module, I identify the costs of finance as a resource, how to make up a budget on the basis of given information and implication of failure to finance adequately. P3 (FINANCIAL DECISIONS) ANALYZE BUDGETS AND MAKE APPROPRIATE DECISIONS How much unbudgeted downside risk you should manage Worst-case scenario (given catastrophic losses) vs. regret The value (and cost) of compliance with regulations (for example, SOX) Real Options: The Value of Midcourse Corrections to Projects One of the fundamental insights of modern financial theory is that options have value. The phrase We are out of options is surely a sign of trouble. However, because corporations (and other organizations) make decisions in a dynamic environment, they usually have midcourse options that should be considered in project valuations: The Option to Abandon a project: Has value if return (or savings) turns out to be lower than expected The Option to Expand a project: Has value if return (or savings) turns out to be higher than expected The Option to Delay a project: Has value if the underlying variables are changing with a favorable trend The Option to Outsource a project: Has value if internal resources dont have required experience and expertise In practice, companies sometimes have other choices. They can delay the decision until later, when more information is available. Or, they can call in outside help, even after having deciding not to do so at the outset. Such investment timing options can dramatically affect a projects estimated mean NPV and risk. Projects that can easily be modified in these ways are more valuable than those that do not provide such flexibility. The more uncertain the outlook, the more valuable this flexibility becomes. CALCULATE UNIT COSTS AND MAKE PRICING DECISIONS USING RELEVANT INFORMATION. Defining Costs There are several types of costs to consider when conducting a breakeven analysis, so heres a refresher on the most relevant. Fixed costs: These are costs that are the same regardless of how many items you sell. All start-up costs, such as rent, insurance and computers, are considered fixed costs since you have to make these outlays before you sell your first item. Variable costs: These are recurring costs that you absorb with each unit you sell. Setting a Price This is critical to your breakeven analysis; you cant calculate likely revenues if you dont know what the unit price will be. Psychology of Pricing: Pricing can involve a complicated decision-making process on the part of the consumer, and there is plenty of research on the marketing and psychology of how consumers perceive price. Take the time to review articles on pricing strategy and the psychology of pricing before choosing how to price your product or service. Pricing Methods: There are several different schools of thought on how to treat price when conducting a breakeven analysis. It is a mix of quantitative and qualitative factors. The formula: Dont worry, its fairly simple. To conduct your breakeven analysis, take your fixed costs, divided by your price, minus your variable costs. As an equation, this is defined as: Breakeven Point = Fixed Costs/(Unit Selling Price Variable Costs) This calculation will let you know how many units of a product youll need to sell to break even. Above the breakeven point, every additional unit sold increases profit by the amount of the unit contribution margin, which is defined as the amount each unit contributes to covering fixed costs and increasing profits. As an equation, this is defined as: ASSESS THE VIABILITY OF A PROJECT USING INVESTMENT APPRAISAL TECHNIQUES. Learning Outcome Assessment Criteria 1.

Outcome: By this module I able to understand the different investment appraisal techniques and nature of long-term decisions. P4 (FINANCIAL PERFORMANCE) EXPLAIN THE PURPOSE OF MAIN FINANCIAL STATEMENTS The three main financial statements are: The balance sheet-which reports a corporations assets, liabilities, and stockholders equity as of a point-in-time (e.g., as of midnight of December 31, 2009). The income statement-which reports a corporations revenues and expenses for a period of time, such as a year, quarter, month, 52 weeks, 13 weeks, etc. The statement of cash flows (or cash flow statement)-which provides information on the change in a corporations cash and cash equivalents during the same period of time as the income statement. The financial statements that are distributed outside of a company need to be prepared in accordance with generally accepted accounting principles (GAAP). For example, the cost principle generally requires that the balance sheet should report long-lived assets at cost minus accumulated depreciation. The matching principle requires that the cost of long-lived assets used in the business be allocated to various accounting periods in which they generate revenues or are used up. ANALYSES FINANCIAL STATEMENTS USING APPROPRIATE RATIONS AND COMPARISONS, BOTH INTERNAL AND EXTERNAL. 1. CURRENT RATIO OR WORKING CAPITAL RATIO: Current ratio may be defined as the relationship between current assets and current liabilities it is also known as working capital ratio. Current assets CURRENT RATIO = Current liabilities Year ended 2007-08 2006-07 2005-06 2004-05 2003-04 Current assets(in crores) 913.27 2333 1614 1171 913.27 Current liabilities(in crores) 1479 994 475 336 213 Ratio 0.62 2.347 3.397 3.485 4.132 Interpretation: A current ratio of 2:1 is usually considered as ideal. If it is less than 2, then it means the company is not enjoying the adequate liquidity. In past five years it shows a decline in the ratios. 2. QUICK RATIO: Formula = Current Assets Inventory Prepaid Expenses Current Liabilities Interpretation: A quick ratio of 1 is considered ideal. In all the five years, it was above 1, where the funds can be properly employed. LEVERAGE RATIOS 1. DEBT EQUITY RATIO: Debt-equity ratio, also known as External-Internal ratio is calculated to measure the relative claims of outsiders and the owners (i.e., shareholders) against the firms assets. This ratio indicates the relationship between the external equities or the outsiders funds and the internal equities or the share holders funds. Interpretation: A DEBT EQUITY RATIO OS 2:1 IS IDEAL. IN 2004-06 THERE IS NO DEBT EQUITY RATIO. IN 2007 AN 2008 IT SHOWED A NEGLIGIBLE VALUE. 2. PROPRIETORY RATIO: It is the ratio between shareholders equity and Total Assets. Formula= Shareholders Equity Total Assets YEAR SHAREHOLDERS EQUITY TOTAL ASSETS RATIO 2004 125.34 1309 0.095 2005 140.71 1651 0.085 2006 285.15 2257 0.126 2007 291.80 3389 0.086 2008 298.65 3987 0.074 Interpretation: A higher the proprietary ratio the better it is In all the five years it is less than one. It shows weak financial position of the business. 3. INTEREST COVERAGE RATIO: It is the ratio between EBIT and Interest Formula = EBIT Interest YEAR EBIT INTEREST RATIO 2004 355 2005 410 2006 499 1 499 2007 693 6 115.5 2008 834 13 64.15 Interpretation: The higher interest coverage ratio the better it is. In 2004 there is no interest coverage ratio. In 2006, 2007 2008 it showed a heavy ration which indicates a greater safety of Out come: By this I understood the basis business and accounting terminology used and should be able to interpret the information collected from financial statements using ratio analysis and could draw conclusions from it. CONCLUSIONS By this module I understood the different long term and short term sources of finance with the implications of choice of one source over the other and any advantages and disadvantages of sources different sources of finance. By this module I identify the costs of finance as a resource, how to make up a budget on the basis of given information and implication of failure to finance adequately.

I Don’t Have a Topic for My Research Paper, So I’m Writing about Nothin

What is nothing? Though at first, the response may seem like little more than a play on words, the simple answer is this: Nothing is not. No word such as anything or everything can be added at the end of the statement to further clarify the crucial concept, which is non-existence: the dictionary definition of nothing. In actuality, though, although the denotation of "nothing" insists on absolute absence and void, in today’s society "nothing" is actually quite present, masquerading as something indeed. Of course, there are concepts in existence that accurately represent our limited understanding of nothing. One such concept is zero. In a simple counting sense, when one, two, or eight hundred items could be present, but there aren’t any, there are zero. Zero items are present, and nothing is there. Kept strictly in a counting sense, this works. Zero is non-existence. Yet, in the actual study of mathematics, one learns that zero may be many things, but never nothing at all. Zero is perhaps the most powerful number in all of mathematics, and its influence on the way we work with numbers is clear. Multiply a number, any number, from the greatest to the small, from positive to negative infinity, by zero. Divide zero by any of these numbers. Zero absolves, absorbs, changes said number completely - it becomes zero. Surely, such a drastic effect cannot be the result of nothing. Divide by zero. Or attempt to, anyway, and find it impossible, "undefined." A graphed function involving a division of zero will form unreachable vertical asymptotes that stretch to positive and negative infinity. Zero, though, does have its weaknesses. Add zero, subtract zero, it’s all the same: no effect at all. The other numbers or variables invo... ...tranger. San Francisco: Knopf, 1998. Descartes, Renà ©.

Fossil Fuels And Alternative Energy Sources :: essays research papers fc

“Shifting Power'; Since the beginning of industry humans have been in search of fuel to power machines and generate energy. Fossil fuels, such as crude oil and coal, discovered beneath the Earth’s surface were found to be an excellent source of fuel. These fossil fuels are burnt in order to generate the energy required to complete various tasks. However, we are now realizing the problems that are created by using fossil fuels to generate energy. These problems are so great that they will force humans to find an alternative source of energy in order to avoid the inevitable disasters that lie ahead. Every day millions of people drive their automobiles to work where they spend the day in a well lit workspace. Yet, they never give a second thought to the source of the energy that their daily lives depends on. Over eighty-five percent of the energy that powers the planet is derived from the burning of fossil fuels (Information 16). Fossil fuels contain impurities and these “impurities such as sulfur also burn and produce potentially dangerous oxides'; which are released into the air (Burning www 1). Releasing these oxides into the air has many consequences including smog, which is the most noticeable of these problems. The hazy smog that hangs over us in the summer is actually ground level ozone; the most harmful pollutant of our air (Information 59). Pollutants of the air we breathe are very dangerous and cause many problems especially to people with breathing disorders. For instance, the E.P.A. estimates that emissions of toxic material like these “oxides'; cause some 2000 cancer deaths a year (Information 61). The rainwater that falls through this polluted air also poses a major risk. Industrial plants and automobiles emit chemicals that mix with the moisture in the atmosphere and form acids that eventually fall to the Earth (Information 89). The same sulfur and nitrous oxides that cause the smog at ground level form nitric and sulfuric acids in the atmosphere (Burning www 1). Upon arrival to Earth this acidic rain damages everything that is falls on. The evidence of acid rain is extremely visible in the damaged forests, polluted soil, and the contaminated plants and animals that are spread around the globe. This acid rain is so damaging it is also blamed for destroying the ancient Greek structures that have previously remained intact (Burning www 2). To add to the list of health and environmental problems associated with the burning of fossil fuels, global warming is also a major threat.

Finding Happiness in Great Expectations :: Great Expectations Essays

Finding Happiness in Great Expectations    Great Expectations is a coming of age novel. This novel is a story of Pip and his initial dreams and resulting disappointments that eventually lead him to becoming a genuinely good man. During his journey into adulthood, Pip comes to realize two diverse concepts of being a gentleman and he comes to find the real gentlemen in his life aren't the people he had thought.    Encouraged by Mrs. Joe and Pumblechook, as a child Pip entertains fantasies of becoming a gentleman. In the eyes of Pip a gentleman is to be wealthy, educated and have a high class, thus Pip's desires. In his mind, Pip has connected the ideas of moral, social, and educational advancement so that each depends on the others. The coarse and cruel Drummle, a member of the upper class, provides Pip with proof that social advancement has no inherent connection to intelligence or moral worth. Drummle is a lout who has inherited immense wealth, while Pip's friend and brother-in-law Joe is a good man who works hard for the little he earns.    Significantly Pip's life as a gentleman is no more satisfying--and certainly no more moral--than his previous life as a blacksmith's apprentice. Pip's desires for educational improvement have deep connections to his social ambition and longing to marry Estella: a full education is a requirement of being a gentleman so he thinks. As long as he is an ignorant country boy, he has no hope of social advancement. Pip understands this fact as a child, when he learns to read at Mr.    Wopsle's aunt's school, and as a young man, when he takes lessons from Matthew Pocket. Ultimately, through the examples of Joe, Biddy, and Magwitch, Pip learns that social and educational improvement are irrelevant to one's real worth and that conscience and affection are to be valued above sophistication and social standing. This new understanding shows Pip who the real gentlemen are.    As Pip grows in age he grows in wisdom and his true identity unfolds as he discovers what it means to be a gentleman. When Pip was young, he knew only of the stereotypical figures of a gentleman. However, Pip comes to the realization that wealth and class are less important than affection, loyalty, and inner worth.

Disease Caused by Environmental Exposure Essay

Environmental Diseases In epidemiology, environmental disease is disease caused by environmental factors that are not transmitted genetically or by infection. Apart from the true monogenic genetic disorders, environmental diseases may determine the development of disease in those genetically predisposed to a particular condition. Stress, physical and mental abuse, diet, exposure to toxins, pathogens, radiation, and chemicals found in almost all personal care products and household cleaners are possible causes of a large segment of non-hereditary disease. If a disease process is concluded to be the result of a combination of genetic and environmental factor influences, its etiological origin can be referred to as having a multifactorial pattern. There are many different types of environmental disease including: * Lifestyle disease such as cardiovascular disease, diseases caused by substance abuse such as alcoholism, and smoking-related disease * Disease caused by physical factors in the environment, such as skin cancer caused by excessive exposure to ultraviolet radiation in sunlight * Disease caused by exposure to chemicals in the environment such as toxic metals * These diseases can also be mutated and can thrive in the unnatural environment through rubbish that isn’t discarded and no sewerage systems. These factors can hurt a nation or an individual quite easily. ————————————————- Categories of environmental disease * First, there are those caused by the ancient metals: lead and mercury. * Then there are those caused by the other metals: arsenic, phosphorus, and zinc. * The newer metals can also cause environmental disease: beryllium, cadmium, chromium, manganese, nickel, cobalt, osmium, platinum, selenium, tellurium, thallium, uranium, and vanadium. * Additionally, there are environmental diseases caused by the aromatic carbon compounds including : benzene, hexachlorocyclohexane, toluene diisocyanate, phenol, pentachlorophenol,quinone and hydroquinone. Also included are the aromatic nitro-, amino-, and pyridilium-deratives: nitrobenzene, dinitrobenzene, trinitrotoluene, paramethylaminophenol sulfate (Metol), dinitro-ortho-cresol, aniline,trinitrophenylmethylnitramine (tetryl), hexanitrodiphenylamine (aurantia), phenylenediamine[disambiguation needed], and parquet. The aliphatic carbon compounds can also cause environmental disease. Included in these are methanol, nitroglycerine, nitrocellulose, dimethylnitrosamine, and the halogenated hydrocarbons: methyl, methyl bromide, trichloroethylene, carbon tetrachloride, and the chlorinated naphthalene. Also included are glycols: ethylene chlorohydrins and diethylene dioxide as well as carbon, acrylonitrile, acryl amide, and vinyl chloride. * Other important chemical causes of environmental diseases are the noxious gases which can be categorized as: Simple asphyxiates, chemical asphyxiates, and irritant gases. The simple asphixiants are nitrogen, methane, and carbon dioxide. The chemical asphyxiates are carbon monoxide, sulfuretted hydrogen and hydrogen cyanide. The irritant gases are sulfur dioxide, ammonia, nitrogen dioxide, chlorine, phosgene, and fluorine and its compounds, which include luroine and hydrofluoric acid, fluorspar, fluorapatite, cryolite, and organic fluorine compounds. While many infectious diseases are caused by human-to-human transmission, others are caused by microorganisms that exist in the outside environment. Scientists from a variety of fields, including medicine and the environment, must work together to address the challenges posed by these environmental pathogens, according to a new report, From Outside to Inside: Environmental Microorganisms as Human Pathogens, released today by the American Academy of Microbiology. â€Å"The key difference between environmental pathogens and other human pathogens is their ability to survive and thrive outside the host. Their widespread occurrence in the environment makes them difficult to monitor and control,† says Gerard Cangelosi of theSeattle Biomedical Research Institute at the University of Washington, one of the authors of the report. â€Å"The fields of medical and environmental microbiology need to be better integrated to stimulate the type of work that is required to combat environmenta l pathogens effectively, and the development and improvement of surveillance and reporting strategies should be a top priority.† Environmental pathogens are defined as microorganisms that normally spend a substantial part of their lifecycle outside human hosts, but when introduced to humans cause disease with measurable frequency. They are carried in the water, soil, air, food and other parts of the environment and can affect almost every individual on the planet. Some examples of environmental pathogens include Legionella pneumophila (the cause of Legionnaires disease, often found in air conditioning systems), West Nile virus, and Cryptosporidium parvum (a parasite that can be found in food, drinking water and recreational waters). In addition to better integration of medical and environmental research, the report recommends more effective monitoring of pathogens in the environment to allow researchers to better understand the incidence and persistence of pathogens in areas that are considered to be at risk for harboring these organisms. Multidisciplinary research must also be fostered to better predict how changes in the environment may affect the frequency of environmental diseases. â€Å"These threats to human health can only be assessed in a comprehensive multidisciplinary context in which ecology, epidemiology, and emerging areas in environmental engineering and microbiology are integrated. This combined approach can yield immediate and long-term health benefits by mitigating established environmental risks, identifying risky situations for disease emerging and finding the causes of diseases of unknown etiology,† says Cangelosi. The report is the result of a colloquium convened by the Academy in February 2004 to discuss environmental pathogens and the current state of research on these organisms. Scientists with expertise in infectious diseases, food microbiology, bacteriology, molecular, microbial ecology, pathogenic mycology and other areas in the microbiological sciences participated. Participants considered the knowledge gaps related to the incidence and epidemiology of environmental infectious diseases, dynamics of human pathogens in the environment, ways to alleviate environmental infectious diseases, research needs in the field and education and communication issues. ————————————————- Causes of Environmental diseases Environmental diseases are caused by chemical agents, radiation, and physical hazards. The effects of exposure, in both natural and work settings, are greatly influenced by the exposure routes: primarily air pollution and water pollution, contaminated food, and direct contact with toxins. Synergistic affects—two or more toxic exposures acting together—are also important, as illustrated by the greatly increased risk of lung cancer in asbestos workers who smoke cigarettes. The potential interaction of multiple hazardous chemicals at toxic waste dumps poses a current public health problem that is of unknown dimensions. Industrial society has introduced or increased human exposure to thousands of chemicals in the environment. Examples are inorganic materials such as lead, mercury, arsenic, cadmium, and asbestos, and organic substances such as polychlorinated biphenyls (PCBs), vinyl chloride, and the pesticide DDT. Of particular concern is the delayed potential for these chemicals to produce cancer, as in the cases of lung cancer and mesothelioma caused by asbestos, liver cancer caused by vinyl chloride, and leukemia caused by benzene. Minamata disease, caused by food contaminated with mercury, and Yusho disease, from food contaminated with chlorinated furans, are examples of acute toxic illnesses occurring in nonoccupational settings. The full toxic potential of most environmental chemicals has not been completely tested. The extent and frequency of an illness are related to the dose of toxin, in degrees depending on the toxin. For chronic or delayed effects such as cancer or adverse reproductive effects, no â€Å"safe† dose threshold may exist below which disease is not produced.

The Hurt Man

â€Å"The Hurt Man â€Å"is a short story written by Wendell Berry taking place in the late asses. The childhood memories of the man Mat Filter are described from a third person narrator whose omniscience is limited to Mat.The fact that the narrator is able to give away information regarding much later events such as â€Å"she would begin to matter to him a great deal in a dozen of years, and after that she would matter to him all his life â€Å"of course referring to Margaret; Mat's coming wife gives the reader the opportunity to reflect on the current events with the future events in mind to each a greater understanding and later conclusion of the story. â€Å"The Hurt Man â€Å"takes on a very traditional short story form. First the characters are described then the setting.After that the banalities and dangers of Port William are portrayed followed by a trigger to lead on the story in a dramatic order: a hurt man arrives bleeding at the house of the five year old narrator a nd his mother. At first the title of the story seems easily analyzable and one might think that the story it called â€Å"The Hurt Man† only because of the hurt man it among other things revolves around. But I live it could also be referring to changes in Mat and how his innocence is taken away when learning of pain through the mother's care of the man. The setting of the story plays a decisive role as well.As stated initially, Mat grew up in a rather tumultuous and harsh setting where disputes were mostly settled out of court with violence; a town in which the â€Å"proof of mortality would be given in blood†. Here a noteworthy word â€Å"mortality â€Å"occurs for the first time in the story and almost from the beginning. The usage of the word mortality later becomes an essential part of the story and Port William. It is also told that the three deceased siblings of Mat are resting at the town's graveyard and their headstones became an immortal proof of their tough and short life in Port William.The mother was a strong and seemingly independent woman. She was treated with respect from the friends of the hurt man first when she stopped them to ask them who they were and secondly when she delegated the different task in an attempt to save the hurt man. Even though she had previously lost 3 of her children at very young ages much like her present son she did not hesitate to let him experience the airdrops of life first handedly. After all such experiences are necessary when growing up especially at that age.Of course she was concerned about his wellbeing to a certain motherly degree also did she love him. So she kept an eye on him but also let him grew up like any other child. Especially on Saturdays did she watch out for him since the town had a tendency to turn additionally disorderly that day. So in contrast Mat's mother is very similar to the mother of Creeps in â€Å"The Soldiers Home â€Å". Both of them want to protect their child but t hey don't want their protection to be arced on them they would rather have their children experience hardships and progress in life.The fact that it is two completely different situations and ages their children are affected by is secondary. The important part is their motherly care and the experiences they let their children have for the better on the long run. Mat was surprised when the mother almost without hesitation let the man inside their house. He was not afraid of man or the blood on his face and body. But if there was one thing he was not surprised about was that the mother took care of him and nursed is wounds. He knew she would do this for she did this to himself so why should his caring mother refuse to help this stranger?He was simply surprised about the facial expression of care, love, empathy and uneasiness which he had only seen directed at him. Then Mat realized what death really is by seeing his mother's genuine care and love for a complete stranger. He also under stood that this stranger would have been dead had it not been for his mother. When Mat then moved closer to his mother and uncovered her facial expression usually only directed at him: that passionate, careful ND worried look he has an epiphany in which he sees the world through the eyes of an adult for the first time.This is a milestone is his life (and life in general) and of course at his age he can only be shocked. For all of his short life Mat thought that the world was revolving around him and his mother only but after seeing how his mother reacted to this man's condition he realized that this man could have died and never returned like the many people buried at the graveyard. He then truly understood what dying means. This might also be the reason why â€Å"she would begin to matter to him a great deal in a dozen of years, ND after that she would matter to him all his life â€Å".First she did not matter to him she could have been a boy for all he cared but he ended up marr ying her maybe because he realized that life does not Just revolve about him and his mother. Through the pain he learned of he also learned about love, care and compassion which he later would share with his wife and grandson and as long as Mat would be happy there would always be a loss† He learned it all his life†. That is the law of equivalent exchange in which we and our universe live by.
