Where Did the Term Horsepower Come From

Today, it has become common knowledge that the term â€Å"horsepower† refers to the power of an engine. We have come to assume that a car with a 400-horsepower engine will go faster than a car with a 130-horsepower engine. But with all due respect to the noble steed, some animals are stronger. Why, for example, don’t we brag about our engine’s â€Å"oxenpower† or â€Å"bullpower† today? Scottish engineer James Watt knew he had a good thing going for him in the late 1760s when he came up with a greatly improved version of the first commercially available steam engine Thomas Newcomen had designed in 1712. By adding a separate condenser, Watt’s design eliminated the constant coal-wasting cycles of cooling and re-heating required by Newcomen’s steam engine. Besides being an accomplished inventor, Watt was also a dedicated realist. He knew that in order to prosper from his ingenuity, he had to actually sell his new steam engine — to lots of people. So, Watt went back to work, this time to â€Å"invent† a simple way to explain the power of his improved steam engine in a way that his potential customers could easily understand. Knowing that most people who owned Newcomen’s steam engines used them for tasks involving pulling, pushing, or lifting heavy objects, Watt recalled a passage from an early book in which the author had calculated the potential energy output of mechanical â€Å"engines† that could be used to replace horses for such jobs. In his 1702 book The Miner’s Friend, English inventor and engineer Thomas Savery has written: â€Å"So that an engine which will raise as much water as two horses, working together at one time in such a work, can do, and for which there must be constantly kept ten or twelve horses for doing the same. Then I say, such an engine may be made large enough to do the work required in employing eight, ten, fifteen, or twenty horses to be constantly maintained and kept for doing such a work†¦Ã¢â‚¬  After doing some very rough calculations, Watt decided to claim that just one of his improved steam engines could produce enough power to replace 10 of cart-pulling horses — or 10 â€Å"horsepower.† Voila! As Watt’s steam engine business soared, his competitors started advertising the power of their engines in â€Å"horsepower,† thus making the term a standard measure of engine power still used today. By 1804, Watt’s steam engine had replaced the Newcomen engine, leading directly to the invention of the first steam-driven locomotive. Oh, and yes, the term â€Å"watt,† as a standard unit of measurement of electrical and mechanical power that appears nearly every light bulb sold today, was named in honor of the same James Watt in 1882. Watt Missed the True ‘Horsepower’ In rating his steam engines at â€Å"10 horsepower,† Watt had made a slight error. He had based his math on the power of Shetland or â€Å"pit† ponies that, because of their diminutive size, were typically used to pull carts through the shafts of coal mines. A well-known calculation at the time, one pit pony could haul one cart filled with 220lb of coal 100 feet up a mineshaft in 1 minute, or 22,000 lb-ft per minute. Watt then incorrectly assumed that regular horses must be at least 50% stronger than pit ponies, thus making one horsepower equal to 33,000 lb-ft per minute. In fact, a standard horse is only slightly more powerful than a pit pony or equal to about 0.7 horsepower as measured today. In a Famous Race of Horse vs. Steam, Horse Wins In the early days of American railroading, steam locomotives, like those based on Watt’s steam engine, were considered too dangerous, weak, and unreliable to be trusted with transporting human passengers. Finally, in 1827, the Baltimore and Ohio Railroad company, the BO, was granted the first U.S. charter to transport both freight and passengers using steam-driven locomotives. Despite having the charter, the BO struggled to find a steam engine capable of traveling over steep hills and rough terrain, forcing the company to rely mainly on horse-drawn trains. To the rescue came industrialist Peter Cooper who offered to design and build, at no charge to the BO, a steam locomotive he claimed would render horse-drawn railcars obsolete. Cooper’s creation, the famed â€Å"Tom Thumb† became the first American-built steam locomotive running on a commercially-operated, public railroad. Replica of the Baltimore Ohios Early Steam Engine, Tom Thumb Beside a Modern Diesel Locomotive. Wikimedia Commons / Public Domain As designed by Cooper, the Tom Thumb was a four-wheel (0-4-0) locomotive with a vertical, coal-fired water boiler and vertically mounted cylinders that drove the wheels on one of the axles. Weighing about 810 pounds, the locomotive was characterized by a host of improvisations, including boiler tubes made from rifle barrels. Of course, there was a motive behind Cooper’s apparent generosity. He just happened to own acre-upon-acre of land located along the BO’s proposed routes, the value of which would grow exponentially should the railroad, powered by his Tom Thumb steam locomotives, succeed. On August 28, 1830, Cooper’s Tom Thumb was undergoing performance testing on the BO tracks outside of Baltimore, Maryland, when a horse-drawn train stopped alongside on the adjacent tracks. Casting the steam-powered machine a disrespectful glance, the driver of the horse-drawn train challenged the Tom Thumb to a race. Seeing winning such an event as a great, and free, advertising showcase for his engine, Cooper eagerly accepted and the race was on. The Tom Thumb quickly steamed to a large and growing lead, but when one of its drive belts broke, bringing the steam locomotive to a stop, the old reliable horse-drawn train won the race. While he had lost the battle, Cooper won the war. Executives of the BO had been so impressed by his engine’s speed and power that they decided to begin using his steam locomotives on all of their trains. While it carried passengers until at least March 1831, the Tom Thumb was never placed into regular commercial service and was salvaged for parts in 1834. The BO grew to become one of the largest and most financially successful railways in the United States. Profiting handsomely from sales of his steam engines and land to the railroad, Peter Cooper enjoyed a long career as an investor and philanthropist. In 1859, money donated by Cooper was used to open the Cooper Union for the Advancement of Science and Art in New York City.

Masculinity As Homophobi Fear, Shame, And Silence - 864 Words

In Michael Kimmel’s pieces â€Å"Masculinity as Homophobia: Fear, Shame, and Silence in the Construction of Gender Identity† and â€Å"Who’s Afraid of Men Doing Feminism† he gives us a description of masculinity and explains what this concept of masculinity means for both men and women. He argues that men can, and should be feminist; that they should advocate for gender equality, because gender equality will benefit both men and women. In this paper I will use Kimmel’s analysis of masculinity, which he uses in his arguments for the necessity of profeminist men, along with some assertions made by Jean-Jacques Rousseau about the education of young boys and girls, to show the strengths and weaknesses of Kimmel’s argument. His assertions can seem strong when read alone, however by looking at his argument for profeminist men together with his and Rousseau’s assertions about masculinity one can see a fundamental flaw in his argument. In his analysis of masculinity he not only points out the significant problems with the way men, especially American men, are forced to subscribe to this barbaric concept of manliness, he also expresses concern for this ‘boys club’ atmosphere. However, in his argument for profeminist men, he takes what could be a strong argument and weakens it when he feeds into this desperate need for reassurance by telling men that feminism will benefit them too. The concept of masculinity has been around for an eminently long time. However, the qualifications for being

Clean Well Lighted Place Free Essays

â€Å"A Clean Well-Lighted Place† â€Å"A Clean Well-Lighted Place† is written by Ernest Hemingway. The subject of this story is life as nothingness. The story starts off with an old deaf man sitting alone in a caf ©. We will write a custom essay sample on Clean Well Lighted Place or any similar topic only for you Order Now There are two waiters who watch and wait on the old man because he has a tendency to drink too much and if this happens they know he will walk out and not pay. The waiter talks about how the old man tried to kill himself because he was in despair; the other waiter asks why he felt despair and the first waiter said the reason was nothing because the old man has a lot of money. The old man is a very nteresting character; we know he once had a wife, but now is alone with his niece. This story portrays the cycle of life and how surroundings can affect our emotional state. In this story there aren’t a lot of details that pop out at the readers. The readers have to read the story over and over again to finally understand it. As the text is read, the old man gets drunk at night at the caf © and likes drinking there because it’s clean and well lighted. The younger waiter tells the old man that there are bars open this late, but the old man likes the caf © because bars are completely opposite of what he ikes. The caf © is well lighted, clean and quiet; bars are loud, dark and dirty which is something the old man doesn’t want to be around. In the caf © there are two waiters that are working; one is older and the other is younger. When reading the story the readers can get an idea of the waiters’ age Just by the dialect. The younger waiter wants the old man to go home so he can go home to his wife. The older waiter tries to explain to the younger waiter that that old man was once married once, maybe even had a family at one point of time in his life, but now all he has is his niece. His niece saved the old man’s life when he tried to kill himself; she cut down the rope when he tried to hang himself. They don’t know why he would kill himself, he had plenty of money. The waiters talked about how he tried to commit suicide and how he did it because he was in despair. The older waiter asked why and the younger waiter said â€Å"nothing†. They were waiting to close up the caf ©, but the old man was still there; yes he was deaf and drunk but he was very quiet and didn’t make much noise. The old man asked for another drink and the young waiter gives him the drink and says the old man, mfou should have killed ourself last week. † (Hemmingway 143). The older waiter tries to explain to the younger waiter that old age is a terrible thing, that one day he will be there and he doesn’t know how he will be or how he will act when he is an old man. The old man waved for another drink but the young waiter refused; the old man paid and left the caf ©. The younger waiter is impatient and insensitive as some would like to argue. He’s excited to go home to his wife, and wants to leave because unlike the old man he isn’t lonely. The text show that the younger waiter says immature comments about the old an because he wants to go home, but he doesn’t think about the old man, he only thinks about himselt. The younger waiter doesn’t think like the old man, old man thinks about many thinks very deeply, yet the younger waiter doesn’t think about anyone, but what the younger waiter doesn’t seem to realize is that he won’t be young forever. In a way he is Just like the younger people in our society now: carefree, young and reckless. As readers can argue young individuals have their whole life ahead of them, so youngsters should be carefree in a way. The older aiter likes to stay late at the caf © Just like the old man and he tries to explain to the younger waiter that the old man likes to stay up because he likes it; the younger waiter Just ignores it and says that he is lonely. The older waiter knows how the old man is because they are both in a way reluctant to go home. The older waiter can relate to the old man because of their age similarity, besides, he walks out without paying. The reason he sides with the old man is because maybe one day he will need someone to keep a caf © open late Just for him. The old man likes staying out late ecause he has nothing to go home to, he says he has insomnia and that many people have that. As readers can argue the older waiter probably tells himself that so he really doesn’t seem alone because older people who have nothing to go home to try to occupy their mind so they don’t wither away in their own depression. Some would also argue Hemingway contrasts light and shadow, maybe the contrast between young and old; impatient and relaxed; family guy and no family guy. Since the old man is deaf, some readers could say it’s a way to distance himself from everyone, like a symbol of separation form the world because he is older.

Ethical Revival of Prudence System †Free Samples to Students

Question: Discuss about the Ethical Revival of Prudence System. Answer: Introduction Qantas Airways owns Jetstar is considered as one of the discount priced airline operator in Australia. JetStar carries more than 8.5% passenger from Australia itself. It has been further seen to operate as per the home and the international network from Melbourne Airport. The primary fleet of the airline operator has been seen to be acknowledged with the A320 and Boeing 787 Dreamliner. Virgin Australia Airlines is discerned as the second principal airline carrier after Qantas Airways. The airline company is seen to be based in Bowen Hills in Brisbane. It has been further seen to be considered in 1999 and operated in one route. The airline carrier is considered to expand itself in 29 cities in areas such as Brisbane, Adelaide, Melbourne and Sydney. The objective has been seen to be based on the important concept which has been seen to be related to the show the methods adopted by both the companies and various types of the other notes from the Auditors Report, Remuneration Report and Financial reports. The final section of the segment of the lessons has been further able to discuss on the rational for the shareholders to invest. Conceptual framework of Accounting for both the companies It has been observed that both the companies have been seen with AASB and Corporations Act 2001. It has been seen that financial report of both the companies has been prepared as the IFRS. This standard is further seen to be issued by the international accounting board. The important consideration for this has been based on the various types of the consideration taken from the financial statements of both Jetstar Airways and Virgin Australia Airlines. This is further seen to be considered as per the historical cost evaluation except in sections of asset and liabilities which needs assessment as per the fair value and other relevant accounting policies (Steenkamp Steenkamp, 2016). The import aspect of the accounting aspect of revenue recognition is seen to be considered as per AASB 118 Revenue, AASB 111 Construction Contracts and Interpretation 13 Customer Loyalty Programmes. The company is yet to implement the AASB 15 Revenue from contracts with the customers, this has been seen to be based on the existing nature of the standards which has been set to be implemented as per the commence date of on or after 1st January 2018. The main activities of the company have been further able to decide if they will be able to swap the AASB 117 for leases and able to change the various considerations of the framework based on AASB 16. AASB 136: Impairment of Assets, is applicable for the recognition of the financial guarantees and the agreement which is seen to be related to the financial guarantees based on the implementation of AASB 137 Provisions, Contingent Liabilities and Contingent Assets (Marshall et al., 2013). Prudence theory applied in both the companies Theoretical application of prudence has been further seen to be based on the fact that none of the company overestimate of total revenues. Virgin Australia and Jetstar has applied the prudence concept based on the financial information which is conservative and the recording of the assets is not underestimated based on the liabilities. It has been further seen that the financial statements has considered the probable transaction into considerations. A variety of the important consideration for the prudence has not been applied as per the AASB 15 Revenue from Contracts with Customers (AASB 15) and the application of AASB 16 Leases (AASB 16). It is seen to be convinced of replacing the existing standards. For testing the viability of the various types of the methods, the companies have been able to decide on test the new method for lease only after 01.01.2019. Other considerations of prudence have been depicted with the regular review of the assets and in terms of assessment of the dec reasing values of these assets. The most important consideration for prudence is evident among both the companies by writing off the values in terms of fixed assets (Barker, 2015). Criteria followed for financial data Total Assets- The total asset of Qantas Airways is standing at $ 17708m in 2016; however the entire asset of virgin Australia is seen to be $ 6886.9 m in 2016. In addition to this, Virgin Australia is not having any amount of the dependent liabilities as on 30 June 2016. In terms of Qantas Airways Ltd, the assets have been seen to be categorised as per the assets held for sale and measured in terms of the fair value less cost of selling. The main benefit of Qantas Airways is seen with the measurement of fair value of plan assets less the present value. The different types of the other consideration has been further seen to be made with the preparation of financial statements of Virgin Australia Airlines with the assets which are not held for the assessment based on financial leases to be recognised at fair value (Wan Norhishamuddinet al., 2015). Tangible Assets and Intangible Assets- It has been depicted with the recognition of the intangible and the intangible assets, with the consideration of non-current tangible assets, which are further seen to be regarded for revenue as per the recoverable amount of the assets. The amortisation is considered as per residual life and useful life as per the date of reporting (Guthrie Pang, 2013). Depreciation The important aspect of Qantas Group has been seen with the depreciation recognition as per straight line basis for PPE except for freehold land. The rate of depreciation of the assets is calculated by total assessment cost is estimated as per the residual values for the various types the useful life of the assets. In a similar way the depreciation and amortisation of the Virgin Airlines is taken into consideration as per the date on which they are classified as held for sale. The depreciation on the PPE is stated as per cost less accumulated depreciation and impairment losses. Same as Qantas, Virgin Airlines recognises the depreciation of the assets with the straight line and estimate the same, with the useful life of the residual value (Microsoft, 2015). Rationale for the shareholders investing in the companies The different types of the considerations made from the directors report has been able to state on the various implication on the shareholders investing in both Qantas Airline and Virgin Airlines. Based on the report of Virgin Airlines, the revenue of the company has been observed to rise from $4,749.2 million to $5,021.0 million. The comparative period has been able to reflect on the total equity which is accounted as 60% of the equity from Tigerair Australia in 16 October 2014. The investor need to further consider on increasing the net operating expenditure from $4,802.7 million to $5,278.7 million. This particular aspect has been seen to be negative for Qantas. The increasing equity has been considered to be conducive for investing in Virgin Airlines (Kober, Lee, Ng, 2013). As per the CEO statement as per the annual report of 2016, is seen to significantly contribute with high figures in 2015-16. The total add to in financial performance is also obvious with the growing operating margin recognised with the increasing EBIT for Jetstar Group, Qantas Loyalty, Qantas International and Qantas Domestic. It has been further discerned that over two thirds of the total remuneration of Qantas has been measured with the international operations, strategy of the portfolio and loyalty business. It needs to be considered by the investors the increasing in the profit before tax from $ 975 m in 2015 to $ 1532 in 2016. As per the financial examination it has been observed that Jetstar (Qantas) is not only in better position than Virgin Airlines and the operating expenses is lower, which makes it a better contender than the latter (Menegatti, 2014). Conclusion The main aspects of the study have able to highlight the present framework of accounting for both Qantas Airways and Virgin Airlines. The a variety of aspect of the study has been able to check for the compliance of the financial report as per the prescribed standard. The conceptual framework of the report has been further seen to be considered as per the AASB and Corporations Act 2001. It has been further discerned from the financial statements that the main accounting framework is seen to be based IFRS. This standard is issued by the international board of accounts. The main consideration of the financial statement has been based on previous cost evaluation, except in some of the areas where the possessions and liabilities needs assessment based on fair value and the relevant accounting policies.

Cancer - Smart Custom Writing Insanity DefenseExecutive summary The insanity plea should be eliminated for assisting criminals get away with murder as well as other serious felonies. Clever defendants have abused the very essence of the plea, thereby securing refuge from criminal punishment. Problems associated with the use of this plea include: difficulties in determining mental illness, differing opinions from psychiatrists concerning the sanity of the same subject, use of money to compromise psychiatrist’s conclusion in favor of the defendant, long time involved in the examination of one subject by psychiatrists thereby resulting to a delayed justice, artificial and crazy behavior by the subject during examination so as to influence the outcome of the examination, lack of scientific as well as an in-depth brain test to diagnose the patient, high cost when a forensic psychologist is involved, and lack of a trustworthy criteria for discharging such subjects from hospital.    Introduction Insanity defense is a strategy applied in law courts by mentally ill defendants to avoid being punished for crimes they committed on the assumption that they were incapable of distinguishing right from wrong at the time the crime was committed. They choose to do this so that instead of being granted jail term, they are given a psychiatric treatment. This concept dates back to the twelfth century although it has undergone some evolution. The original version of the plea didn’t intend to have the defendant found no guilty on the bases of inability to distinguish wrong from right but intended to have the defendant awarded a pardon or a way of mitigating the sentence. Its only in the nineteenth century that the argument of having the defendant acquitted on this basis arose. This paper will discuss the risks that come with the use of the plea and why it should be abolished. This plea has been widely abused by criminals to procure acquittal and that’s why its of interest to m e. Objectives The research seeks to identify the risks involved in the use of the insanity plea in the judicial system. Research methodology To achieve the desired research objectives, both primary and secondary sources of information were made use of. The primary sources included questionnaires given to professionals in the legal fraternity quite conversant with the concept and historians who are well versed with the genesis of the concept. The secondary source of information was basically library research targeting books and articles touching on the subject. Main body Continued use of this plea is the surest way to make the world itself insane and unpredictable. Imagine a suicide bomber who is caught on the verge of detonating the bomb and when taken to court, invokes this plea to procure acquittal (Pasewark 100). One major problem with insanity plea is the difficult involved in determining mental illness. What the proponents of this concept fail to realize is that, there is a big difference between insanity and mental illness (Pasewark 101). As a matter of fact, only some few mental illness constitute insanity. Insanity on the other hand is comprised of not only mental illnesses, but mental deficiencies as well. The two words are actually used in different disciplines of knowledge and it would therefore be wrong to equate them. Insanity is used in the legal arena and is therefore not a medical word. Problems therefore arise as experts try to apply a medical theory to a legal matter (Pasewark 104). Differing opinions from the psychiatric community as far as the sanity of one individual is concerned further subjects the concept to gross abuses (Manchester 112). Furthermore, the world is slowly giving in to corruption as a way of life and therefore the psychiatrists can be compromised to say that the defendant is insane. Money or lack of it can therefore play a very crucial role in the success or failure of an insanity defense. The determination of insanity is the preserve of court psychiatrists (Manchester 115). It’s important to realize that this determination can take dozens of sessions and even fail to come to a solid end as far as the mental condition of the defendant is concerned. This therefore ends up having a serious impact on the trial as well as its outcome. This results to big files of undecided cases and this waters down the credibility of the judicial system (Manchester 116). The determination largely involves behavior study. A defendant equipped with this kn owledge can decide to behave artificially so as to influence the outcome of the examination. This compromises the accuracy of the examination . No body puts the accuracy issue in a better word frame than Thomas Sowell in his book titled Insanity defense published in the year 1994, â€Å" psychiatrists and psychologists are often put in the same position as economists who are asked to predict things that no one is capable of predicting. Those with the honesty and realism to say they can’t do it are likely to be brushed aside†¦Ã¢â‚¬  (Sowell 10). Psychiatrists also have a tendency of identifying with people in their social as well as economic class (Fass 125) . This is the lot they are likely to describe better. If the case is involving a defendant in a different social and economic class as the psychiatrist, then the psychiatrist is very likely to be oblivious of the defendant’s problems. This means that the jury handling the case would base its verdict on a poorly researched conclusion. Sowell, 1984 gives a case that illustrates this behavior of psychiatrists. A forensic psychologist is quoted as saying â€Å" I hate to say this, but I don’t like to work with poor people†¦Ã¢â‚¬ ¦..They are talking about stuff that doesn’t interest me† ( Sowell 325). The fact that psychiatrists are also not required by the court to accompany their conclusion with some scientific backing makes the concept vulnerable to even more abuses. They do not even carry out an in-depth brain test to diagnose the patient. Psychiatrists arrive at their verdict via mere observance of the subject and then deciding based on their beliefs (Fass 126). If the case requires the services of forensic psychologists who are paid professionals, then accessibility problems set in especially if the defendant cannot afford the charges required (Fass 127). The concept is clearly a loophole used by defendants who conspire with rogue psychiatrists to get away with felonies and murder (Bonnie 85). A case in point that clearly illustrates this is the acquittal of the gentleman who attempted to assassinate President Rogan Reagan. This attempt was carried out in the full glare of the public and was captured in cameras. Hinckley earned an acquittal despite the evidence connecting him with the felony (Bonnie 87). This attempt brought up unprecedented public outcry. Psychiatrists involved in the case concluded that he made the attempt in an effort to impress Jodie Foster, an actress he had become obsessed with. The decision of the psychiatrists was based on observance as well as the upbringing of the suspect as opposed to scientific proves which would be more accurate and reliable (Bonnie 88). The fact that somebody for instance , masturbated for several years as an adolescence cannot be used to justify a felony of this degree. After a person is awarded acquittal courtesy of this plea, the law requires that such a person is taken to a mental institution where he/she is supposed to stay until a doctor proves that the person is no longer dangerous and therefore can coexist with others in the society (Manchester 121). A lawyer is also required to accent to this. The procedure of determining this is as untrustworthy and compromised as that of determining the insanity itself. For instance, Sowell, 1994 gives a case of one man by the name Kemper, E . E who earned acquittal after murdering his grant parents. This acquittal was based on the insanity plea. This man was therefore send to an hospital in accordance with the law. He spend about five years in the hospital after which he was dismissed after convincing psychiatrists and the judge that he was now cured and could coexist with others in the society. He did this by giving rational answers to the psychological test he was subjected to. Three years later, he fou nd himself behind bars again for killing eight women one of them being his mother. This casts a lot of doubt on the criteria used to discharge such subjects from hospital. This plea should therefore be abolished in favor of the â€Å" guilty but mentally ill â€Å" concept. In this case, the defendant would first be taken to hospital for psychotherapy and then once he/she is mentally fit, serve the remainder of the sentence in jail (Sowell 20) . Conclusion The paper has discussed the reasons as to why insanity plea should be eliminated from our judicial system. They have included: difficulties in determining mental illness, differing opinions from psychiatrists concerning the sanity of the same subject, use of money to compromise psychiatrist’s conclusion in favor of the defendant, long time involved in the examination of one subject by psychiatrists thereby resulting to a delayed justice, artificial and crazy behavior by the subject during examination so as to influence the outcome of the examination, lack of scientific as well as an in-depth brain test to diagnose the patient, high cost when a forensic psychologist is involved, and lack of a trustworthy criteria for discharging such subjects from hospital.    Works cited    Bonnie, R etal. â€Å"Decision Making in Criminal Defense: An Empirical Study of Insanity Pleas and the Impact of Doubted Client Competence† , Journal of Criminal Law and Criminology, Vol. 87, 1996.

Phase 1 Discussion Board 12 - Assignment Example not be satisfied by the reasoning provided and therefore for them it is essential to list down the factors, rank them according to priority and then explain the reasoning behind it. Before setting up a plant for carrying out the manufacturing operations it is important for Autoedge to understand the supply and demand of the raw material in that area. Autoedge before setting up a manufacturing plant must analyze the demand of the product in that area and figure out whether or not it will be easily for the firm to procure raw material for making the product. Autoedge before carrying its manufacturing operation must also keep in mind that the product they are manufacturing must not fall short as per the demand of their customers and vice versa. It must also research about the brands of automobile that are preferred in those areas. The company cannot succeed in the long run if it does conducted effective research before establishing its manufacturing plant (World Trade Organization, 2013). As the economies become more integrated as Autoedge offers services throughout the globe, therefore the political and economic risk associated with its locations increases. Autoedge while selecting the location for its manufacturing operations must consider the areas that are more politically stable, or are not impacted by unstable government or as a result of terrorism. The areas that are not politically stable affect not only the businesses in those areas but also the consumers and national economies depending on the nature of the product or service being offered by the firm. The GDP of any country is considered an important factor for the location of a manufacturing plant. The amount and number of products being manufactured in a particular country attracts businesses. Businesses usually prefer setting up their plants in country with high GDP in order to maximize their profits. The country that has a flourishing economy usually serves as a profitable location for almost any

John bull's other island - Essay Example al observer of ‘Irishness’ and his love-hate relationship with the English middle-class are played out by his two principal characters, Broadbent, a middle-class Englishman with a ‘colonial’ mind-set and the expatriate Irishman Doyle, who has no illusions about the Ireland of the early 20th century. A foil for the protagonists is added with the one-time priest Keagan, who is appalled by the impending land re-possessions. Regardless, Shaw has him acknowledge that maybe British efficiency may be better than ‘patriotic fools’. Shaw was somewhat dismayed by his critics failure to understand the character of Keegan, when he said â€Å"I shown the Irish saint shuddering at the humor of the Irish blackguard--only to find †¦ the average critic thought the blackguard very funny and the saint very impractical† (Shorter qtd. in Henderson 619). When the play was first performed, praise was copious - Edward VI was said to have laughed so much, his chair broke – but so was criticism, with Chesterton accusing Shaw of ‘being liable to fits of admiration for the British’, although condemning them elsewhere (Auden in Kronenberger 619) There had been other criticism and in response, Shaw allowed himself to be interviewed by The Tatler, stating that far from being frivolous, he had been deadly serious, showing †¦the Englishman to the Irishman and the Irishman to the Englishman, the Protestant to the Catholic and the Catholic to the Protestant†¦ taken that panacea for all the misery and unrest of Ireland (the Land Purchase Bill) †¦ and †¦ shown at one stroke its idiocy, its shallowness, its cowardice, its utter and foredoomed futility. (Shorter in Henderson 619). The reception of the treatment of the latter was even more mixed, which can only makes sense in the light of British ignorance of the Ireland of the early 20th century, with its large families, ‘progressively pauperized by primogeniture’, and its absentee landlords

Section 2. Wound aetiology Select a common wound type (e.g. diabetic foot ulceration, pressure ulcer, leg ulcer, fungating wound, dehisced surgical wound), which you have cared for in your role as a qualified nurse. It may help to reflect on a patient you have cared for with this type of wound. Using contemporary literature to support your work, discuss: What your chosen wound type is How this type of wound develops (including contributory factors) How this type of wound is recognised (common characteristics) Who it affects Prevalence in UK and home country Approximate word count: 800 _______________________________________________________________________________ Your answer here: One of the common types of wounds is diabetic foot ulcer. International Working Group on the Diabetic Foot (2010) defined diabetic foot ulcer in their research system as a full-thickness penetration of the dermis of the foot in a person with diabetes. According to Jeffocoate and Harding (2003) diabetic foot ulceration is a common complication of diabetes and it is disabling and frequently leads to leg amputation. It usually occurs as a result of neuropathic, vascular changes of a diabetic foot, foot deformities, plantar callus and smoking (NICE, 2010). Even though the cause of diabetic peripheral neuropathy is uncertain, it is known that the nerve function of a diabetic patient degenerates in response to metabolic changes, pressure and ischaemia (Alexander, Fawcett Runciman, 2000). On the other hand, the presence of high sugar level in the blood such as sorbitol can cause osmotic swelling and subsequent damage to the nerve cell, increase the risk of vascular disease and can also give rise to neuropathy and increase the risk of infection (Falanga, 2005; Watkins, 2000). Pendsey (2010) stated that the neuropathy in diabetic patients is manifested in the motor, autonomic and sensory components of the nervous system. In motor neuropathy, the innervations of the intrinsic foot muscles are damaged that leads to an imbalance between flexion and extension of the diabetic foot. It also affects the muscles required for normal foot movement altering the distribution of forces during walking. This creates anatomic foot deformities that make abnormal bony prominences and pressure points and causing skin reactive callus at the sites of abnormal load. It then gradually causes skin breakdown and ulceration (Pendsey, 2003). In sensory neuropathy, it affects the peripheral sensation, subsequently loss of sensation that makes the patient unable to feel trauma to their lower extremities. Patient will also feel heaviness, insensitivity to heat, cold and pressure. It is estimated that 45-60% of all diabetic ulcerations are due sensory neuropathy (Frykberg, Zgonis, Armstrong et al., 2006). According to Alexander et al (2000) when mechanical forces continue to be applied on the affected area, it leads to inflammation, abscess formation and, eventually, ulceration. This is also the reason many wounds go unnoticed and get worse progressively since the affected area is continuously subjected to repetitive pressure and shear forces from ambulation and weight bearing without noticing it. In autonomic neuropathy the peripheral nerve function is affected, which controls the distribution of blood through arteriolar vessels. One of the signs and symptoms is decreased perspiration in the lower extremities which make the skin becomes dry and increasingly prone to fissures (Alexander et al. 2000). Moreover, poor blood supply to the foot or ischaemia is another significant risk factor for diabetic foot ulceration, which according to Frykberg et al. (2006) it often occurs in combination with loss of sensation and the researchers also said that an estimated 45% of diabetic ulcers are due to ischaemia and neuropathy. Diabetic foot ulcer is commonly found in areas where the abnormal pressure distribution arises from disordered foot architecture. It is usually located on hallux, first metatarsal and fifth metatarsal heads, and under the heel (Grey, Enoch Harding, 2006). The precipitating causes of foot ulceration and infection are friction in ill fitting or new shoes, untreated or self treated callus, foot injuries, burns, corn plaster, nail infections and heel friction in patients confined to bed (Watkins, 2003). According to International Working Group on the Diabetic Foot (IWGDF) diabetes is global epidemic with devastating human, social and economic consequences. The disease claims many lives and places a severe burden on healthcare systems and economies everywhere, with the heaviest burden falling on low and middle income countries such as Philippines. It is estimated that 250 million people worldwide have diabetes, equating roughly 6% of the adult population with the age group 20-79 years. The number is expected to reach about 380 million by 2025, representing 7.1% of the adult population. This is due to the current lifestyles which is lack of exercise and not having a proper diet. A survey conducted by Morgan, Currie, Smithers, Butler and Peters (2000) revealed that foot problems occur in nearly 20% of diabetic patients. Two-thirds of lower extremity amputations are performed in diabetic patients alone, and a majority of these are preceded by a foot ulcer. Nwabudike and Ionescu-Tirgoviste (2008) set out a study to identify the clinical parameters associated with foot ulceration in diabetic patients. The study suggested that older age diabetic patient poses the risk of developing foot ulcer because of decreased ability to self care, including personal daily foot examinations. This is also a result of poor vision and impaired mobility which also predispose patients to trauma. The study also shows that most patients with ulcer were type 2 diabetic patients and this correlates with the age of the patient group. The average duration of diabetes the patients have was of 11.5 years. It is twice more common in males may be due to the active nature of the activities th at men are engaged compared to women, increasing the likelihood they may suffer from trauma. In Nwabudike (2008) research, it also showed that lack of awareness of the disease process and personal care increasing the likelihood that the ulcers may degenerate and leads to gangrene and amputation. Section 3. Wound Assessment Identify features of your chosen wound aetiology (wound type) that are commonly identified during the assessment process. Now select one of these features and critically discuss different ways of assessing this problem. You must link your discussion to the contemporary wound care literature. Here is a list of wound features commonly identified during assessment: Odour Exudate Infection Wound bed tissue e.g. slough, necrotic tissue Your discussion must make clear which aspect of wound assessment you have chosen and include an exploration of the different options available for measuring, describing and documenting it. Approximate word count: 500 Your answer here: Accurate wound assessment is essential for the appropriate and realistic planning of goals and interventions for patients with wounds (Collier, 2003). Diabetic foot wound has two classifications, the neuropathic foot ulcer and neuroischemic foot ulcer. Differentiating between these entities is essential because their complications are different and they require different therapeutic strategies (Pendsey, 2007). Neuropathic wound has no sensation and foot is warm to touch with intact pulses. The ulcerations are usually located on tips of toes and plantar surfaces under metatarsal heads. It also shows oedema, local necrosis and sepsis. On the other hand, ischaemic ulcer is painful upon rest and usually diminished sensation over period of time. Moreover, the foot is not warm to touch and has no pulse. The ulcerations are often located on margins of foot especially on the medial surface of the first metatarsophalangeal joint and over the lateral aspect of the fifth metatarsophalangeal joint. They also develop on the tips of the toes and heels. Signs of sepsis, necrosis or gangrene are also noted. An established clinical tool TIME which is adapted from Watret (2005) is being used for assessing the wound bed. The acronym stands for tissue, infection, moisture balance and advancing or undermining epithelium. Necrotic tissue, slough and eschar are non-viable tissues that can be found on diabetic ulcer that needs to be removed through debridement while the presence of epithelial tissue and granulation tissue in the wound suggests healing. The unhealthy granulation tissue often dark in colour and frequently bleeds on contact are signs of infection. Moisture in the wound bed needs to be assessed too. Moist is known to stimulate healing by promoting granulation and encouraging debridement, nevertheless, moisture balance should be maintained to prevent the wound from becoming too dry and too moist which could delay wound healing. In addition the wound edges and environment will be assessed for migrating epithelial cells which is a good sign of healing or maceration which suggest poor care. Infection is a major factor that affects the time healing of all wounds. Jeffcoate and Harding (2003) said that infection can cause substantial deterioration and delay wound healing. Infection is an invasion and growth of pathogenic microorganisms in the body. Diabetic foot infection is divided in three categories: superficial and local, soft tissue and spreading or cellulitis, and osteomyelitis (Jeffcoate Harding, 2003). The classic signs of infection are: heat, redness, swelling and pain. Other signs such as increase exudates, delayed healing, odour, and abnormal granulating tissue are also suggesting infection (Grey et al, 2006). Cutting et al (2005) and Edmonds (2005) used a checklist for identifying infection in diabetic foot ulcers. In the checklist, there are four areas; under it are the signs and a box opposite to it to check if certain signs are present. Clinical signs of infection: Cellulitis- acute inflammation of tissue lymphangitis phlegmon- purulent exudate pus/abscess crepitus in the joint erythema increase in exudates volume localised pain malodour probes to bone. Systematic signs of infection: Nausea Fatigue Vomiting Fever chills Probe to bone test: bone palpated no bone involvement Wound culture: wound swab required wound biopsy required. Furthermore, the wound infection continuum of Gary, White, Cooper and Kingsleys (2005; 2010) is also use to measure the extinct of infection. It is also a useful adjunct in identification of treatment objectives. The scoring is from 3-0; score of 3 means spreasing infection and 0 is colonised. Moreover, Gray et al (2010) also have the wound exudates continuum; it identifies presence of infection since excessive exudates suggest infections. Section 4. Wound Management Using the same wound feature that you identified in Section 3; critically discuss the different ways there are of managing this problem. Your discussion must include: The different types of wound care dressings, products and treatments that could be used to manage this problem Other appropriate/related aspects of patient care such as nutrition and positioning How the patient experience can be improved Now select one of your identified dressings and answer the questions in the product information table below: Product information table Name of dressing (the company name) AQUACEL Ag Hydrofiber (Convatec, Hull, UK) Category of dressing (the generic name) Hydrofiber Wound Dressing with Ionic Silver Indications for use Use on acute and chorin wounds, including burns, surgical wounds, diabetic foot ulcers, pressure ulcers, and leg ulcers Contra-indications Aquacel Ag Hydrofiber should not be used on individuals who are sensitive to or who have had an allergic reaction to the dressing and its components such as Na Carboymethylcellolose and silver. Its not compatible with oil-based products, such as petrolatum jelly. Sizes available 2x 2, 4x4.7, 6x6, 8x12, 75x18, 39x18 Adhesive or non-adhesive? Non-adhesive dressing Secondary dressing needed required Moisture retentive dressing such as DuoDERM Extra Thin or Versiva Approximate word count: 1000 Your answer here: Management of diabetic foot ulcers are removal of callus, eradication of infection, and reduction of weight bearing forces, often requiring bed rest with the foot raised (Alexander, Fawcett Runciman, 2000). A large proportion of patients with diabetic foot ulceration will develop infection, including osteomyelitis or bone infection and gangrene (OMeara et al, 2006; McIntosh, 2007). An infected diabetic ulcer needs immediate medical attention. Jude (2007) stated that infection is a major factor that delays wound healing of a diabetic ulcer. It may be necessary to undertake surgical debridement and drainage of pus. Then a wound swab will be taken from the floor of the ulcer after the callus has been removed. A culture of the excised tissue may provide more accurate information (Watkins, 2003). This will help identify the infective microorganisms and the appropriate antibiotic therapy to be given (Alexander et al., 2000). According to Watkins (2003) patients with superficial ulcer infection can be treated with oral antibiotics such as amoxicillin, flucloxacillin and metronidazole. Since the most likely organisms to infect superficial ulcer are staphylococci, streptococci, and sometimes anaerobes. For patients with deep infections should be hospitalised and started on broad-sprectrum antibiotics. Surgical debridement should then be carried out, which should include all the devitalised tissues, sloughed tendons, and infected bones. Jude (2007) said that diabetic foot ulcers generally have multiple organisms isolated from within the wound and methicillin-resistant Staphylococcus aureus (MRSA) is an important vancomycin and teicoplanin can be given to patients infected with MRSA. Anyhow, linezolid can be an alternative which can be administered orally. Furthermore, various topical antimicrobials, antiseptics, and antibiotics have been used also in treating infected diabetic foot ulcer. Topical antibiotics like neomycin, bacitracin, neomycin, gentamycin, polymyxin B, mupiricin, fusidic acid, and topical antiseptics are also used in infected foot ulcers. Although antiseptics and antibiotics are widely used, there is insufficient evidence for their use in diabetic foot ulcers (Jude, 2007). Lipsky, Holroyd Zasloff (2008) studies showed that pexiganan cream can be used as an effective alternative to oral antibiotic therapy in treating mildly infected diabetic foot ulcer and might decrease the risk of selecting antimicrobial-resistant bacteria. Dressings also play an important role in managing infected diabetic foot ulcers. There are various dressings available in the market nowadays. The selection of a dressing will depend on the condition of the ulcer. Most infected diabetic foot ulcers produce copious amount of exudates and pus. Dressings are used to control exudates, maintain a moist wound healing environment and eradicated the microorganisms that cause infection. The appropriate dressings for infected wounds with exudates are foam, alginates, hydrofiber, and hydrocolloids that are combined with silver ion. Silver has been shown to have bactericidal properties and has been used in wounds as an antimicrobial for more than century. It acts by impairing the bacterial electron transport system and some of its DNA function. It kills the microbes on contact through multiple mechanism of action, such as inhibiting cellular respiration, denaturing nucleic acids, and altering cellular membrane permeability. Nowadays, Silver ions have been incorporated in hydrofiber, foam, hydrocolloid, and alginate dressings (Bergin Wraight, 2006). Concreet Foam dressings with silver can be used during inflammatory phase following debridement and desloughing. It also kills microorganisms on the wounds. It is very absorbent that can be left undisturbed for 3-4 days. However, it can cause a drying effect on the wound if there are too little exudates. Hydrofiber dressings such as Aquacel Ag absorb the exudates, protecting the edges of the wounds from maceration at the same time kills the bacteria in the wound. Alginate dressings is use as a primary dressing and for packing wound, it is good for deeply ulcerated wound with high exudates. Another dressing is hydrocolloid; it is best use on wounds with granulating and epithelialising wounds that with low to moderate amounts of exudates. The primary dressings therefore should be either foam-based such as Contreet foam (Coloplast;Humlebaek, Denmark) or hydrofiber AQAg (Aquacel Ag; Convatec, Chester,UK), both of which will absorb the exudates. A moisture retentive dressing can be used as a secondary dressing such as DuoDERM Extra Thin or Versiva. One advantage with the hydrofiber dressing is its capacity to hold wound exudates and microorganisms within its fibres where the bacteria are then eradicated by the ionic silver (Jude, 2007). In addition, the used of hydrofiber dressing in exudating wounds has been proven with research. Jude also implied to improved outcomes in infected diabetic foot ulcers and ulcers that are colonised, one should consider silver dressings as an essential adjunct to wound care to improve its wound bed and to facilitate healing. Studies also revealed that patients treated with AQAg primary dressing showed improved healing and more overall ulcer improvement with less deterioration in the ulcer. Once the acute situation has resolved it will be necessary to ensure redistribution of the weight-bearing forces on the vulnerable foot by the use of specially constructed shoes or moulded insoles. Application of a total contact plaster cast, lightweight scotch cast boot, or air cast boots may help healing. These conform to the contours of the foot, thereby reducing shear forces on the plantar surface. Great care must be taken, especially with the fitting of plasters, to prevent chafing and subsequent ulcer formation elsewhere on the foot or ankle (Watkins, 2003). If recurrence of neurophatic ulceration is to be avoided, regular follow-up by a chiropodist will be required. An ongoing podiatry to remove excess callus and provide nail care regular assessment, look for active lesions and treat immediately, detect and manage deformities, callus, skin cracks, and discoloration, simple sensory test, examine pulses such as dorsalis pedis and posterior tibial, assess ankle reflex and assess other sensory modalities (Alexander, Fawcett Runciman, 2000). The patients experience will be improved by having a highly structured care. The patients infected ulcer shows healing improvement and prevent from amputation. Understanding the diabetic foot, the proper examination of the patients feet, investigations to classify the foot ulcers, and proper management techniques using a team approach, along with preventive steps, will go a long way in limb salvage and prevention of foot amputation (Pendsey, 2010). Section 5. Evidence based guidance Identify a contemporary source of evidence based guidance (i.e. a clinical guideline) which could be used as a basis for providing a high standard of care to patients with this type of wound. Critically discuss how the guidance given in this document might influence your nursing practice including whether you believe there are any omissions or recommendations made that would be difficult to manage in your own clinical setting (Phillipines). You must clearly state the full reference of your chosen guideline document and link your work to other healthcare literature where appropriate. Approximate word count: 500 Your answer here:

Teaching Philosophy :: Free Essays Online

Teaching Philosophy My teaching philosophy is that teachers need to relate the concepts that students learn to the world around them. Students attend an educational institution to prepare for future employment and to enter the real world. The basic skills that are needed to survive in society are taught in the classroom like reading and writing, but students must also be taught that the concepts that they are learning in the classroom will prepare them for the rest of their lives. The concepts that a student is learning must affect his or her life directly. To be more specific, students should be able to feel as if the subject matter that he or she is learning is somehow related to them and has an affect on the world that they live in. Students need to be able to relate to their school work to supplement further engagement. The more that a student feels they can relate to a specific subject, the stronger the possibility that the student will continue to be eager to learn the subject. For example, in an English classroom, students should be able to see themselves in an aspect of the literature they are reading. A group of seventh graders may have a hard time relating to a book about someone who is 5 years younger then them, but they may be eager to find similarities between themselves and a character that just happens to be of the same age. Showing your students that you care about their world allows your students to see that you care about them. If a teacher cares enough to relate the subject matter to a situation that may be occurring in his or her student’s lives, then the student will appreciate it. It motivates a student to excel and makes the teacher seem more approachable to the students. For example, the teacher should chose
