Characters in Dr.Faustus Free Essays
Faustus ââ¬â The protagonist. Faustus is a brilliant sixteenth-century scholar from Wittenberg, Germany, whose ambition for knowledge, wealth, and worldly might makes him willing to pay the ultimate priceââ¬âhis soulââ¬âto Lucifer in exchange for supernatural powers. Faustusââ¬â¢s initial tragic grandeur is diminished by the fact that he never seems completely sure of the decision to forfeit his soul and constantly wavers about whether or not to repent. We will write a custom essay sample on Characters in Dr.Faustus or any similar topic only for you Order Now His ambition is admirable and initially awesome, yet he ultimately lacks a certain inner strength. He is unable to embrace his dark path wholeheartedly but is also unwilling to admit his mistake. Mephostophilis From the Hebrew, mephitz, destroyer, and tophel, liar. A devil of craft and cunning. He is the devil who comes at Faustusââ¬â¢ summoning, and the devil who serves Faustus for 24 years. In lore, Mephostophilis (also spelled Mephistopheles, or Miphostophiles, and also called Mephisto) seems to be a relative latecomer in the recognized hierarchy of demons. He possibly was created for the Faustus legend. In Marloweââ¬â¢s play, Mephostophilis has layers to his personality. He admits that separation from God is anguish, and is capable of fear and pain. But he is gleefully evil, participating at every level in Faustusââ¬â¢ destruction. Not only does Mephostophilis get Faustus to sell his soul; he also encourages Faustus to waste his twenty-four years of power. Wagner Servant to Faustus. He steals Faustusââ¬â¢ books and learns how to summon demons. At the end of the play, he seems concerned about his masterââ¬â¢s fate. Good Angel and Evil Angel Personifications of Faustusââ¬â¢ inner turmoil, who give differing advice to him at key points. Their characters also reflect Christian belief that humans are assigned guardian angels, and that devils can influence human thoughts. Valdes Friend to Faustus, who teaches him the dark arts. He appears only in Act One. Cornelius Friend to Faustus, who teaches him the dark arts. He appears only in Act One. Lucifer Satan. ââ¬Å"Luciferâ⬠original meant Venus, referring to the planetââ¬â¢s brilliance. In Christian lore, Lucifer is sometimes thought to be another name of Satan. Some traditions say that Lucifer was Satanââ¬â¢s name before the fall, while the Fathers of the Catholic Church held that Lucifer was not Satanââ¬â¢s proper name but a word showing the brilliance and beauty of his station before the fall. He appears at a few choice moments in Doctor Faustus, and Marlowe uses ââ¬Å"Luciferâ⬠as Satanââ¬â¢s proper name. Belzebub One of Luciferââ¬â¢s officers. A powerful demon. The Seven Deadly Sins Personifications of the Seven Deadly Sins, not acts but impulses or motivations that lead men to sinful actions. They array themselves in a pageant before Faustus, although scholars think now that this section was not written by Marlowe. Clown / Robin Robin learns demon summoning by stealing one of Faustusââ¬â¢ books. He is the chief character in a number of scenes that provide comic relief from the main story. Dick A friend of Robinââ¬â¢s. He is one of the characters peopling the few comic relief scenes. Rafe A horse ostler, or groomer, and friend to Robin. With the Clown, he summons Mephostophilis, who is none too pleased to be called. Vintner A wine merchant or a wine maker. This Vintner chases down Robin and Rafe after they steal a silver goblet from him. Carter A man who meets Faustus while carting hay to town. Faustus swindles him. Horse-Courser A man who buys Faustusââ¬â¢ horse. Faustus swindles him. Hostess An ale wench. She treats Robin and his friends kindly. The Pope Yeah, that Pope.

The Agency Problem free essay sample
The preliminary and primary goal of a company is to maximize its firm value, in other words, to maximize the shareholdersââ¬â¢ wealth. As a good instrument tool of measuring the firm value or the operation condition of a company, the share price indicates the stock market value of the companyââ¬â¢s shares. Shareholders always expect to maximize the share price by corporate governance, however, managers in company always link their attitude to the their own interest, and they would not to try their best to achieve shareholderââ¬â¢s goal. Due to different interests in shareholders and managers, the conflicts always exist between them. An agency problem occurs when the interests of stockholders, the board of directors, and/or the management of the company are not perfectly aligned or when these entities conflict. EXPLAINATION Agency problem is typically caused by two reasons which are asymmetric information and hidden action. There is no legitimate theoretical or moral objection to those who assert that the goals of the modern corporation should be to serve the broad interests of all stakeholders rather than to serve the narrow interests of just the shareholders. In a large company, the principle refers to the shareholders of the company and the agent refers to the managers who is the subordinates in the company. Due to the separation of the ownership, managers are always responsible for the more detailed jobs (including job planning, supervising the sales ),the owner of the company do not have to supervise all the business in firm and managers sometimes would maximize their own profit. The behaviour mentioned before is hidden action. Moreover, managers have to run the company on a day-to-day basis, hence they hold more information related to the jobs or tasks. This will lead to different strategies and tactics made by managers, and managers could attach the documents such as financial reports and the accounting data but the shareholders only have the access to the annual reports. Hence there is a problem of hidden information which means managers may keep some information for their secrets instead of reporting to the shareholders. As a result, managers may pay attention to their own interest or profit primarily instead of the firm value then the company have to afford the agency cost. According to the agency problem, some obvious conflicts between owners and managers formed agency cost. For instance, some managers would over-consuming the perks in the company, they may use the company public resources as their own resources. It incurred in cars, office equipments and managers often use the company resource after work, for example, a manager drive the company car to pick up his friends for dinner and if he did this every single day, there will be a certain amount of cost to the company. Another example is that a manager may come up with sub-optimal decision for expansion or larger market volume. It supposed that Nokia is not well-performanced in market and the manager of the Apple company may consider to merge the Nokia company and buy the company in a cheaper price. Hence to do so, it seems that Apple has larger market volume but their performance may not still keep as well as before, in other words, empire building. The Adidas company bought the Reebok company several years ago, but larger market volume do not assist Adidas to compete against Nike, and this is still a kind of agency problem. Consequently, these conflicts and incorrect decision or expansion formed barrier of the profit-maximizing. In addition, managers have to focus on only one project and decide to accept or reject the project by its NPV value. It brings more risk to managers compared to shareholders because the owners or shareholders of the company could have number of choices of investment, in other way to say, shareholders put eggs in different baskets, and it always brings profits for shareholders, however, itââ¬â¢s difficult for managers to take long-term for-profit projects, what managers prefer is the short-run project with low cost. The return for managers is always related to their performance and once they choose the low cost projects, its easier to make a profit for themselves. Mentioned before is still a kind of agency problem. To choose the correct corporate management in a company is necessary to solve the agency problem. Corporate governance describes the various mechanisms and institutions, including law, contract, and norms, by which shareholders and other outside investors attempt to assure themselves that management will be faithful guardians of their investments. Some of the governance may lead to a cost to the company, for instance, the following three items belong to agency cost which are designing the contract, enforcing the contract and the residual loss respectively. According to Journal of Economic Literature (March 2010), one firm has more of the attribute but weaker performance, while the other firm has less of the attribute but better performance (which is indicated as in the diagram), and companies hence have to take correct steps of strategies instead of just putting more governance attribute. To avoid these cost, the company take the potential safeguards as steps. The main parts are organisational structure, external audit, remuneration packages. Organisational structure is to set more positions for managers instead of the owner of the company only. The advantages for this is that more managers in the company such as operating manager and financial manager, they could monitor each other and it saves time for the owner to supervise the two departments. Managers have their competition in company and once one of the managers put more effort on work, the others would put the same effort due to the competition pressure. As a positive circle, all the managers would do contributions to the company instead of considering their own profit before the firm value. Second one is the external audit. The external audit plays important role in checking whether the reports for investors are correct or not. Managers may hide some information about the financial data and the audit could find the incorrect item and the report the error to the shareholders on time so that make sure the reliability of the data and reports. The remuneration package is still an efficient approach to take the company into correct situation. In broad terms, compensation packages for managers and directors include cash, stocks and stock options. Agency theory tells us that the extent of ? nancial leverage in the corporate capital structure (i. e. , the debt-equity mix) has signi? cant managerial incentive effects. In some companies, shareholders show the reference on the stock option. Stock option is a kind of incentive option which allows the managers or directors buy the shares as much lower price as the market price. Managers are willing to do this but once they buy more shares of the company, they would become be part of owners, the potential risk is that if the share price of the company is going down, the managers share price would go down together. CONCLUSION Agency problem seems to form a barrier of the development of the company but shareholders could reduce the agency cost even remove the problem through correct management. If managers have a disutility of e? ort and are paid a wage then they will have an incentive to shirk rather than act in shareholdersââ¬â¢ interests. It is therefore important that managersââ¬â¢ incentives are aligned with those of shareholders. Managers would finish their jobs efficiently once they are in profit-maximizing situation. Maybe the situation makes a cost to the company, hence shareholders have to find a balance of this as a result so that the firm value and the managersââ¬â¢ profit are maximising in synchrony.

Arugmentative essay on which is better the pc or the mac computer
Arugmentative on which is better the pc or the mac computer - Essay Example Both fruit would have supporters lauding the differences in inherent nutritive value, taste, and texture of each. When we compare an Apple Mac to a MS Windows PC, two traditional feasible choices for personal and business computing, though, the subjective should be thrown out of the window and the facts wisely considered. While it is true that Windows has been ââ¬Ëvirallyââ¬â¢ (pun intended!) popular, the time has come for certain misconceptions about the Mac to be cleared up and how it will be a very good choice. The inevitable argument against the Mac is that it is more expensive than a Windows PC. While at times true, the fact is it often costs less than or about the same as its Windows counterpart. A Windows PCââ¬â¢s cost does not include multimedia software and hardware that you will need or want. By buying the extras, you pay more than the cost of a Mac which comes bundled with software like iLife. Consider long-term savings: Macs have been proved to be less expensive to run than Windows. The reputable CIO magazine quoted an Enterprise Desktop Alliance survey as finding the total cost of ownership (TCO) with a Mac to be much lower than a Windows PC. ââ¬Å"Macs were cheaper in six of seven computer management categories: troubleshooting, help desk calls, system configuration, user training and supporting infrastructure.â⬠(Kaneshige).

They were stories that were silly about turtles or butterflies or the basic type of scenario for a children's book. However, they were also stories that had morals to them. I remember being read to almost every evening by my dad, a magazine that was one of my favorites. I looked forward to those magazines not only because my father would be reading me something new but also I got the mail. I enjoyed these stories and was never ready for bedtime until I had heard my story. When looking back on the instant that I began to really remember learning to read was not really reading at all. Instead, it was recollecting. I remember my grandmother reading me my favorite story. It was a book that I would always try to talk someone into reading to me. While she was reading the story, I had heard it so much that I basically had it memorized. When she stumbled upon some of the words or did not read it completely correct as I had had it memorized, I told her, ââ¬Å"Grandma, that is not what it says there.â⬠She would give me a puzzled look and have to correct herself to my own personal satisfaction but she was amazed at my memory of the story almost verbatim. That was the first memory I have of a milestone that taught me how to read. It was not exactly what one would call reading, but it was through word recognition. When I think back to learning how to read, I realize how differently I learned based on that milestone. While I was a fairly decent student growing up, I had my own methods of learning to read and expand vocabulary. Back then, it was a big deal to teach phonics in the classroom at a young age. This then would place emphasis on learning how to sound out words. I really struggled with phonics.

Literature review - Essay Example The study revealed that the patientsââ¬â¢ wellbeing improved with better nurse staffing ratios such as skills and the hours of work spent on the patients (Castle & Anderson, 2011). Nurse staffing is an imperative aspect in determining the quality of services offered in hospitals and patient outcomes. Nurse Staffing Ratio and Quality Outcome in long-term care. I selected this topic because of the existence of research gaps on the topics investigating the existence of inefficient services in many health facilities and homecare due to understaffing. However, before examining the connection between clinical outcomes and nurse staffing, it is imperative to note that this research faces common challenges that are likely to crop up during the process of designing the staffing outcomes. For instance, the issue of getting suitable data sources that are reliable; correct measures for patient outcome and staffing and the problem of establishing authentic linkages between the two variables to come out with valid conclusions. According to Spilsbury et al. (2011), nurse staffing is a primary responsibility of the hospital administrators. The researchers go ahead to pinpoint budgetary constraint considerations and the nurse labor markets as some of the factors that influences nurse staffing ratios in hospitals. Moreover, according to the agency nursing staff model the hours assigned to each staff in a subunit within the facility and nature of supervision form another set of elements that significantly influences the nurse staffing (Spilsbury et al., 2011). The quality of care provided by the nurses is greatly influenced by the characteristics of the individual nurse such as fatigue, knowledge, and experience. The quality of care is also, affected by the system in which nurses work because it involves staffing levels and the needs of patient under care; organization of colleague officers, their availability, support services as well as

Determinants for Demand in Private Housing
Determinants for Demand in Private Housing Principle determinants of demand for private housing. The dominant factor is price. Providing all of the other factors remain equal, one would expect a fall in price to increase demand. This increase occurs for two reasons. Firstly, the product has become better value for money and therefore becomes a preferred area of expenditure for consumers. Secondly, it enables consumers to purchase the product in replacement of a previously purchased inferior product. Household Income. As incomes rise, so does the household purchasing power. Therefore, the consumer is better able to afford products. Comparables. In incidence where, apart from price, there is a direct comparison between two products, as prices fall on product b) so consumers may substitute it for product a) where there has been no fall in price. Taste and preference. Consumer tastes and preferences change. These may be affected by outside sources such as promotion or peer pressure. In this event, such changes will have an effect on demand. Expectations. The perception of future changes in price will affect demand. If prices are expected to rise in the future, present demand will increase, and visa-versa. Therefore, if it is expected that private house costs will rise, but the present cost of purchase falls (i.e. mortgage payments), because consumers generally view property rental as inferior to private ownership, the demand for private housing will increase. Difference between supply of new housing and manufactured goods New Housing The Supply of new housing has limitations. The principle limitation is itââ¬â¢s fixed core element, the land. Although there can be changes made in the use of land, for example from agricultural, it is a limited resource that cannot be easily expanded. As a result, it is considered a fixed cost. Every individual product (house) will require a significant element of land for manufacture. The relative scarcity of the supply of land, this has the affect of increasing the cost of supply. Manufactured goods The supply of manufactured goods can be more easily increased. Once the fixed costs are in place, i.e. property, plant and machinery, these are equally divided over the number of goods produced. An increase in the number of products manufactured will therefore reduce the fixed cost element per unit. For example, fixed costs of à £100 spread over 1,000 products will be one tenth of that cost if it is spread over 100 products. Comparison of affordability with effective demand for a product Concept of affordability The concept of affordability (Marshall et.al. 2000) in respect of property rental is threefold. 1) That such rental is set at a level, which does not force the tenant into a position of poverty. 2) That it does not consume more than 25% of the tenantââ¬â¢s affordable income and 3) that the lessee is left with sufficient funds to be able to afford other basic necessities. Concept of effective demand The concept of effective demand is based upon the premise that supply and price determines demand. Whilst taking into account the available budget of consumers, effective demand works on the basis that increase of supply reduces cost, which enables lower price and therefore fuels demand. The motives for these concepts vary in that the affordability concept is based upon social precepts, whilst effective demand is based upon profitability and price. Other Criteria The criterion for assessing affordability is centred on five key issues. There needs to be an effective analysis of the RSLââ¬â¢s[1] own rental levels. Such analysis should determine rent averages by authority area, levels as calculated in relation to the type of property and the area in which the property is located. Comparison of rental levels with other RSLââ¬â¢s. Comparison of rental levels with other rental organisations. For example, those in the private sector. By evaluation of the income levels and type of household, for example single parent, pensioners, families etc. Formal assessment. Within this issue, RSLââ¬â¢s need to determine that households have sufficient income level to be able to afford the rent and still be able to achieve a certain standard of living. It is also needs to assist in reducing the reliance of tenants on other benefits by providing them the opportunity to rejoin the employment market. Other criteria that could be used include locality of tenant to work concentration areas, which would reduce tenant expenditure and increase job opportunity. Expectation of affordable housing schemes An ideal affordable housing scheme should provide occupiers with reasonable living accommodation sufficient for the needs of the household unit, at the same time allowing a standard of living that provides for all their basic needs. For the provider who finances the scheme it should allow for a reasonable return on their investment, plus sufficient capital replacement to enable them to continue the provision of such housing. Learning Activity 10 Supply differential between houses and other household product requirements Supply of houses differs from other products such as cars, white goods and luxury goods in that it is not as easily adaptable to meet demand. A car can be readily supplied and that supply rapidly replaced. This is not the position with a house. Here the supply source takes longer to react to any movement in price, because of the motivation of the house seller. A number of factors that affect supply, such as the motivation of the occupier to sell. If they are satisfied with their accommodation and the location, they are less likely to sell, limiting supply. Similarly, if they perceive prices will continue to rise, they will delay selling, a reverse effect will happen when house prices are depressed. Houses completed The chart above generally shows that the increase in house prices has not been met by a significant rise in the level of new builds, in fact, House builds supply has remained at a similar level throughout the ten years from 1995. If one wanted to construct a genuine graph for new house other data would be required, including variety of construct, for example flats, houses etc, and take into account the population demographics. Learning Activity 12 Scarcity Scarcity occurs within the social housing market where there is a lack of availability of the core element of house building, namely the land, and where house occupiers do not put their houses up for sale. Opportunity cost Many landlords have seized the opportunity of increasing their housing stock during the periods of deflation or housing slumps. In such cases, there is a need to weigh this cost against future gains. The conditions of demand In the housing market if the price is right and compares favourably with other housing options, such as renting, and that price is within the budget of the householder, then they will purchase a property. This is generally the preferred route of households. The conditions of supply To conditions that determine supply is the availability of products, in this case houses, at the right price. Supply will also be affected by the future expectations of the market in terms of price. Perverse demand behaviour In the housing market the major action that perversely affects demand is the substitution behaviour. Consumers generally perceive house ownership being preferable to renting and will therefore seek to move to this status as soon as is possible. External effects Several external situations affect the housing market. These include the inability of young people to get onto the property market; changes in employment conditions and types of households. Similarly, issues such as planning and taxes will affect the market supply and demand. Sources of inefficiency Inefficiencies within the housing market, particularly with social housing, where results of data analysis do not take into account all of the relevant factors and the resources are not being used to create the maximum economic welfare.. Sources of inequity issues Inequity can arise in the housing market because of the house-building programme failing to keep pace with the rate of demand. Monopoly power Monopoly power exists where there is no alternative to the product cost or the method of acquisition. It gives a monopoly the ability to affect the price of their product without reference to market trends. Nostradamus Housing Association Nostradamus is a social housing organisation. They are faced with a situation of reduced occupancy as a result of mortgage rates being reduced to a level where repayment are at a significantly lower level than the association charges. The occupancy issue is exacerbated by the fact that the council has transferred its housing stock to another association. Current research shows that the trend in the move to ownership is likely to continue for the near future. Therefore Nostradamus have decided to sell off their surplus stock, under a right to buy scheme, in order to rectify itââ¬â¢s worsening financial position. HA Rented Housing Owner-occupied Housing Low cost housing Reduction of mortgage rates Selling of houses Ownership Right to buy Within the case study presented, we see that the association is operating a system of allocative efficiency, in that the sale of their houses benefits them by reducing their financial difficulties, thereby making the business more efficient. It is equitable to both parties, as the association benefits by reducing its financial difficulties and the occupier benefits by acquiring a property at a cost, which is less than they were previously paying. It is found that owner-occupied housing is also provides equity, as it assists with the distribution of wealth between individuals who were previously disadvantaged. Thus, the association is also fulfilling its role in economic welfare. Determinants On Demand Owner-Occupied Housing Market price of product Rent exceeds mortgage payments, therefore exceeds market price Levels of household income Incomes have improved as the region is recovering economically Comparable prices The cost of ownership is below that of the rent being charged making rents no longer comparable Taste and preference Generally consumers prefer ownership, seeing renting as of lower social standing. Expectations Those who are moving to ownership expect to benefit from better neighbours. The sale of redundant houses by the association does give rise to a number of criticisms in addition to the fact that these were transferred from the local council. One of the most important criticisms is that it leaves the association with a much lower stock of houses, thereby it would be ill prepared to be able to provide housing for those who need social housing, should the local economy suffer a future reverse of fortunes in the future. A further criticism is that such houses could have been utilised to reduce the difficulties being experienced in other areas of the country. With areas such as the South East suffering shortage of low-cost housing for rent or sale, there could have been some relocation effected to have reduced this difficulty. This would have also have had the effect of assisting those in need in those areas by providing them with the opportunity of possible work as well. Furthermore, by selling the houses below the original cost, the association can be said to ha ve misused council funds. These funds essentially would have been provided by the members of the local community, through the payment of local taxes. As a result of all of these issues, a criticism could be levelled at the association that it failed in its duty of social care and welfare by not undertaking a study of other possible ways in which it could have utilised the excess housing stock and, at the same time, addressed its financial issues. The social imbalance could have been addressed in other ways. Primarily, it could have been offered to the government at an equitable rate, for use in helping them to address local and national homeless problems. This would have satisfied the issue of welfare. Secondly, the association should have looked at the possibility of reducing the rate of its rent to that which would be comparable with current mortgage payments. This would have led to higher levels of occupancy and increased the income of the association, thus reducing over time the level of its cash flow difficulties. The third way of reducing the social imbalance would have been by helping to address the issues that first time buyers suffer, namely not being able to gain entry into the property market. In line with other organisations, the association should have looked at the possibility of a ââ¬Å"Rent and Buyâ⬠scheme. Under this scheme, the buyer purchases part of the property equity and the association purchases the balance, for example, the buyer may buy forty percent and the association sixty. Over the years, and as the buyerââ¬â¢s income levels rise, under this scheme the buyer would be able to then purchase the remainder of the property equity, on an instalment basis, from the association. These future equity purchases would have been at current market rates. This would have had the additional benefit of enabling such people to be able to remain within the location of their choice, close to families and their work environment. Accounting Issues Indicators Loss of Income Increasing turnover of tenants. Rentals too high Reduction in ownership mortgage rates Improvement in local incomes Housing turnover exceeding budget Tenants attracted by ownership Rentals too high.

Tender is the Night Book Response Essay -- Literary Analysis, Fitzgera
Fitzgerald accommodates various central themes throughout his novel Tender is the Night. In the novel we witness one of the main characters, Dick, regress from being a man of great social stature who is portrayed as an exalted person whom we idolize as a reader, to a man who loses everything and has his life decimated by the end of the novel. This constructs one of the foremost themes of the novel, Dickââ¬â¢s transformation over the course of time. Additionally we see many people for the duration of the novel who have thoughts of affairs, actually carry out affairs, and those who just have abounding thoughts of affection for members of the opposite sex. Rosemary acquires fondness for many different men. Dick actually has an affair with Rosemary, and Nicole has an affair with Tommy Barban. This initiates the prevalent theme of affairs throughout the novel. In addition, the way Dick epitomizes a father figure to many women in the novel is a theme as well. The central character in Tender is the Night, Dick Diver, starts out as someone whom we admire as a reader until his world falls apart in the end of the novel. Rosemary is infatuated with Dick in the beginning of the novel. Rosemary feels as if ââ¬Å"Against his hard, neat brightness everything faded into the surety that he knew everythingâ⬠(31). The characters in this novel are captivated by Dickââ¬â¢s mesmerizing personality; ââ¬Å"to be included in Dick Diverââ¬â¢s world for a while was a remarkable experienceâ⬠(27), ââ¬Å"He won everyone quickly with an exquisite consideration and a politeness that moved so fast and intuitively that it could be examined only in its affectâ⬠(27-28). It is also expressed that ââ¬Å"Dickââ¬â¢s attention seemed to paralyzeâ⬠(33) McKisco while engaging in a conversation ... ... she has never had a palpable father. Dick acts as that father when they are married and provides her with the same type of affection that a father would have for his daughter. Dickââ¬â¢s transfiguration over time, affairs, and Dickââ¬â¢s embodiment of a father figure to women are all considerable themes of the novel. These themes help present to us the different aspects of this time period. Obviously during this time affairs were rampant among married individuals. Along with that we see how women of this time depended on men to some extent because of the way Dick is a father figure to many women. Furthermore, they help us see how Dick is affected by his job and we see how dealing with mental patients takes its toll on him over the course of time. Each of these distinct themes contributes to the understanding of the novel as a whole and greatly assists the reader.

Mccarthyââ¬â¢s Novel the Road Is About Manââ¬â¢s Inherent Altruism in a World of Selfishness
The man in The Road is portrayed as a very religious individual, this is indisputable. One could deduce from this that therefore he is selfless in protecting his son and carrying on in the times in which he finds himself. This viewpoint contrasts with the one that the man is selfish with his actions, doing everything to survive and not helping anyone he meets on his journey. All the decisions the man makes throughout the novel can be used as examples to argue each point of view, and it may be that it is a mixture of both. Maybe the man acts in a selfless way due to selfish beliefs. The whole image of religious self-sacrifice by the man is probably what McCarthy intended, this can be seen through his determination to preserve his sonââ¬â¢s life. An example of this is when he defends his son from the man from the truck. He risks everything by shooting the man as this leaves only one bullet in the chamber of the revolver, as he intends to use it in a life threatening situation to kill his son, it means that he will probably die while suffering. His whole determination to stay alive could be seen as to only keep the boy alive, this is seen as selfless as he only wishes to help the boy survive, not himself. This altruism is directly connected to the manââ¬â¢s solid belief in god and in what he is doing. Throughout the novel other peopleââ¬â¢s selfishness can be seen, the cannibalism and stealing juxtapose with the manââ¬â¢s proper behaviour; he tells his son that they would never eat someone and shows generosity towards the old man. Cannibalism is an indication of how people act immorally in the novel in order to stay alive in the novel, the man refuses to do this and is therefore portrayed as having a higher morality than anyone else. On the other hand one could identify the manââ¬â¢s behaviour as purely selfish, he has a fixed idea in his head, he is protecting his son for his own given mission to be complete. The man does not wish to help anyone other than himself, he only reluctantly helps the old man when his son insists, and happily takes the clothes off a defenceless man later on, returning them only again as a result of his sonââ¬â¢s persistence. He acts immorally on several occasions, not offering assistance to the man who had been struck by lightning and locking the people in the basement again when he had discovered them instead of helping. It could be argued that everything an individual does is aimed at personal gain, selfishness, either physical or psychological. The man is certainly benefiting psychologically from keeping his son alive as he believes he is doing the right thing and fulfilling his purpose. Also his religious morality can be questioned, as he considers suicide even though this is not allowed according to the bible. The fact that he does not become a cannibal may be used to identify him as still retaining some kind of moral code, however, he does anything to keep him and the boy alive and it is not improbable that in a situation of severe starvation he would have turned to cannibalism had it been an option. From all of his actions in the novel, the reader can justifiably come to the conclusion that the man is just as selfish as the other people trying to survive in the post-apocalyptic world. The man can certainly be described as selfless as well as selfish, he aims towards a noble goal but does not let anything stop him, and he identifies otherââ¬â¢s lives as less important than the boyââ¬â¢s. Even though he is not described as committing highly immoral actions such as cannibalism, it cannot be ruled out that from his actions we can deduce that this is what he would have turned to had the situation permitted it. On the other hand does acting immorally indicate acting selfishly, in the novel it certainly does but this may not actually be the case, it may be argued that the immoral actions by the man are done to help the boy survive. McCarthy links selfishness to immoral actions quite strongly in the book and so due to this the man is presented to the reader as selfless, this was the intention of the writer and the reader will most probably grasp this attitude while reading the book. Upon further thought however, it may be seen that the man is simply selfish and there is nothing more to him than that.

European Settlers in the New World essays
European Settlers in the New World essays Title: Fell, Barry. America B.C.: European Settlers in the New World. New York: Quadrangle/New York Times Book Co., 1976. Author: Howard Barraclough Fell (1917-1994). Fell is an accomplished marine biologist from Harvard, also became the professor of comparative zoology at Harvard. An interest in languages and societies encouraged him to teach himself most the languages he knew. His controversial interpretations often served only to enrage mainstream archaeologists. Scope: In this book, Fell lays out the evidence showing that there were numerous pre-Columbian contacts between Europe, Africa, and Asia and the New World going back at least three thousand years. Thesis: This book rounds up a wide range of epigraphic material which he claims demonstrated settlement by a variety of West European and Mediterranean voyager. Summary: The inscriptions are written in various European and Mediterranean languages. They speak of visits from ancient ships and of permanent colonies of Celts, Basques, Libyans, and even Egyptians. These findings came to light in 1975 in the course of an archeological survey of New Hampshire and Vermont. The book states that three thousand years ago bands of roving Celtics crossed the North Atlantic to discover North America. Phoenician traders came to join with the Egyptian miners and became the Wabanaki tribe, these people wrote in ancient Celtic alphabet called Ogam. As one historian, Professor Norman Totten, has pointed out, it means that 2,500 years of American prehistory must now be transferred to history; for history begins when writing begins. You can infer from the writings that the colonists intermarried with the Amerindians and so their descendants still live today. Conclusion: Before I read this book, my knowledge of pre-Columbian discoveries of the Americas was limited to what we discussed in class. After reading this book, I have been enlightened to many ...

Cardiac Pacemakers Essays - Cardiac Arrhythmia, Free Essays
Cardiac Pacemakers Essays - Cardiac Arrhythmia, Free Essays Cardiac Pacemakers CARDIAC PACEMAKERS The heart is bestowed with a specialized system that automatically generates rhythmic control via the sinus node, located in the superior lateral wall of the right atrium near the opening of the superior vena cava. The specialized pacemaker cells dictate control of the rest of the heart through regular electrical impulses that propagate from the right atria to the lower ventricles. The rapid conduction of these impulses cause the muscle cells of the atria to contract and squeeze blood into the ventricles, which contract and force blood into the aorta and pulmonary arteries. Abnormalities of the heart rhythm, called arrhythmias, can disrupt this normal cardiac control making it necessary to use some artificial means to regulate the rhythm of the heart. Today, some half a million men and women, most of them over the age of sixty, carry implanted cardiac pacemakers that take over the duties of the natural conduction system. Tens of thousands of these devices are implanted each year in t his country alone. Over the past thirty years cardiac pacemakers have evolved from simple devices only capable of fixed-rate stimulation of a single chamber of the heart to more sophisticated implanted computers that medical personnel can interrogate and reprogram from outside the patient's body. These refinements have allowed for more physiologic pacing with maintenance of atrioventricular synchrony and cardiac output. There are various types of cardiac pacemakers available today that can be surgically implanted to treat specific arrhythmic disorders in the heart. Abnormal rhythms in the heart are one of the most frequent causes of heart malfunction, and in most cases necessitate some type of cardiac pacing unit. Cardiac arrhythmias are common in the elderly, in who age-related physiologic changes often alter the conduction system of the heart. Such changes may remain asymptomatic, or they may progress to syncope, or possibly sudden death. In the event of acute myocardial infarction, arrhythmias are no more frequent in the elderly than in younger subjects; in fact, ventricular premature beats are seen less commonly in patients aged seventy years and older. Age is also not a factor in determining the success of resuscitation from cardiac arrest, although it may be a predictor of six-month survival. In general, there is nothing unique about arrhythmias in the elderly. All of the commonly encountered arrhythmias may be seen in older patients. Arrhythmias may occur in otherwise normal hearts, but with increasing age, associated cardiac disease becomes more likely. A possible exception is atrial flutter; in younger patients, its presence almost always indicates a serious cardiac disorder. There are two indications for antiarrhythmic therapy: relief of symptoms and prevention of more malignant arrhythmias. In elderly patients, pacemakers are the preferred treatment for Brady arrhythmias. Most arrhythmias occur in response to the aging heart. In the sinoatrial node, the number of pacemaker cells decreases, until often less than 10% of the normal complement remains after age 75. Beginning at age 60, there is a detectable loss of fiber from the fascicles of the left bundle branch. Commonly, less than one-half the original number remain, the others having been replaced by fibrous tissue. Micro calcification is often found in this region, and can be related to both age-associated change and pathologic processes. There is also some fibrous tissue replacement of conduction fibers in the distal conduction system, as well as occurrences of fibrosis and hyalinization in the media of the blood vessels supplying the conduction tissue. Any of these age related processes can lead to a disrupted rhythmic and conduction system of the heart. One type of arrhythmia, bradycardia, normally necessitates the surgical implantation of a pacemaker device. Bradycardia is a circulatory condition in which the myocardium contracts steadily but at a rate of less than sixty contractions a minute. This condition may be normal in some physically fit people, where their pulse may be quite slow. This is because an athlete's heart is considerably stronger and is capable of pumping a larger volume of blood per heartbeat than someone who is less physically active. However, in other people, cardiac output is decreased which can cause faintness, dizziness, chest pain, and eventually syncope and cir culatory collapse. The cause of bradycardia can be an increase in the parasympathetic nervous

Contract Law Essay Example | Topics and Well Written Essays - 750 words - 1
Contract Law - Essay Example Trietel distinguishes the obligations arising out of a contract on the basis of mutual agreement between parties3. The ââ¬Å"consideration,â⬠which Stone defines as ââ¬Å"what one party to an agreement is giving, or promising in exchange for what is being given or promised from the other sideâ⬠4 in this case is 2000 pounds, payable to Alexander Constructions, for completing the excavation. However, when Alexander Constructions strikes the thick layer of rock, it is promised an additional 500 pounds by Brown in the interest of getting the work completed on time. This is not however, a part of the original consideration that has been spelt out in the contract. Brown may be able to reply on the precedent in the case of Stilk v Myrick5 to refute the payment of an extra 500 pounds, since Alexander Constructions was only carrying out the excavations which were already a part of the original contract. In the Stilk6 case, Stilk was a sailor who was promised additional pay to get the vessel back to London when two other sailors deserted ship. The Court however held that under the terms of his contract, Stilk was obliged to cope with emergencies and had therefore done nothing beyond his contractual terms to justify additional pay. This could be applied to the case of Alexander Constructions as well. However, a similar situation arose in the case of Hartley v Ponsonby,7 where a sailor sued for additional pay that was offered to get the ship back when other sailors deserted ship. But in this case, the Court fund on behalf of the sailor and he was granted the additional pay. The only difference in these two cases lay in the fact that in the Stilk case, the number of sailors who deserted was only two, hence the condition of the remaining sailors was not dire and they should have been able to cope. As opposed to this, in the Hartley case, there were substantial desertions,

Sylviaââ¬â¢s was established in 1986 targeting the local bank employees and serviced offered at that time according to their choices and preferences and this is why it was so popular in its childhood. Not only this, Sylviaââ¬â¢s bar was only late night bar on the high street which opened after 11pm, and for this reason people from local pubs, who want to spare more time, used to come there as those pubs used to close at 11pm. But, now a days, this area is not that much popular and many younger prefer the fashionable Canal district for weekend night outs. This segment of people doesnââ¬â¢t have 80s or 90s mentality, lifestyles, choice of relaxation. Now trend has been changed and people like to relax in weekend nights in crowdie nightclubs with group of friends and colleagues where they will be provided regular priced dishes, wines, cocktails etc with remix tracks by popular DJs rather than like to spend the time of their relaxation in a silences environment especially in a bar where old classical songs and premium priced dishes and cocktails are available. The business strategies of Sylviaââ¬â¢s might work in a pores city like London where many community of traditional, classy

Mining has however been a major threat to terrestrial biodiversity in Manitoba through land conversions and pollution (Wellington, 1997). A key environmental concern in mining has always centered on the rehabilitation of old, orphaned mines which consist of steep excavations, shafts and exploration trenches. Despite mining being a key revenue generator for Manitobaââ¬â¢s government, public safety has been compromised after abandoned mines are left unattended since such mines pose a threat to local communities living nearby. The Mine Closure Regulation which was approved in 1999 led to the establishment of The Orphaned and Abandoned Mines Program (OAMS) mandated to deal with such mines by sealing them using Otto Bayerââ¬â¢s Polyurethane foam (PUF) technology (Priscu et al, 2009). Many of these aba ndoned sites are situated within the Precambrian Shield which has massive gold deposits. Provincial Parks, aquatic life and areas with dense vegetation have not been spared due to discovery of more valuable metal deposits under them which eventually results in encroachment by the mining industry. Industry plays a major part in Manitobaââ¬â¢s development. However, hazardous waste mainly originates from Manitobaââ¬â¢s industries and exhibit a variety of harmful radiological, corrosive, bio hazardous, explosive and toxic properties.

The Kennedy Space Center Essay Example for Free
The Kennedy Space Center Essay I am the most typical American man who is born in Pensacola Florida. Most people dream of visiting Florida, but I get to live there. What I find interesting about Florida is that it was part of Spain until 1845, when it became a State of the United States; making it the twenty seventh State to join the Union. Most of the population in other states has to shop at a grocery store for oranges or orange juice, but for myself, orange groves are nearby and I can smell the fresh ripe oranges that ripened on the trees and are available for my breakfasts for when ever I chose. What I find humorous at times when I hear other people speak of Florida is our Alligators and that we should be fearful of them. But we are not, they are just part of our life style and they are much protected from the government. Even if the Alligator is walking on a sidewalk, it is illegal to remove them, the ideal of the situation is to give them total respect and stay out of their way. With the ocean nearby, I get to fish when ever I can. Living with my grandparents, my grandpa always went with me. After casting out our lines, I always surrendered to one of his famous stories about the fish the got away. I chuckle to myself just remembering those stories, but one thing for sure; it was a time when my grandpa Willy and I would bond the most. At the end of the day, I would stand side by side with Grandpa Willy and clean our daily catch, often having races to see who could beat who. Sometimes the scales would fly! When it would be done and over, the smell of fresh fish would fill our senses, making all that work worth while. In my spare time, I sit in front of my television playing video games. Halo is my favorite! I like it because it is a combat game with lots of action. I get to be the Master Chief who fights to protect my planet. There are aliens who come from far away to fight to take over my planet and I have to fight them and kill them to protect the planet. I utilize all my army gear to fight these distorted aliens. I even go to their planets with my Banche which is a flying aircraft and is loaded with necessary weapons to succeed my strengths mission. The object is to take over their planet as well. If I use the Blanche, or the Warthog or I may chose to move in the tank, what ever the case may be, I am assured to have the necessary weapons to be successful. When I am not playing the video games, I am a typical male who checks out the ââ¬Å"hottiesâ⬠at the mall. My buds and I just hang around, trying to look not interested but we donââ¬â¢t miss a thing. But the ways I have some down time is to put on my headphones and jam to the ââ¬Å"Beastie Boyââ¬â¢sâ⬠, and look through some car magazines. I like to get my hands dirty and love hearing my engine of my 1969 engine purr. I spent many pain staking hours working on that machine, but I successfully was able to soup up my car and am the envious of many of my peers as I drive it to my school. Finally, when I am done with school, I am going to concentrate on becoming a lawyer. Thinking of our Sunshine State and all of our sixty seven counties I feel there is room for someone like me who will work hard to help out with some areas like International Trade; Tourism, which Florida has seventy six point eight million visitors alone in 2004 and is the top traveled state; Space Industry, which employs something like fifteen thousand employees at the Kennedy Space Center; Agriculture, Florida leads with farming income from orange groves and orange juice and the University Research, five million dollars are being sponsored for research at the Florida University. I feel no matter what area of law I would go into, I would be protecting companies or people. No matter if I would be working in Space or working for the common farmer; what ever the case may be I feel it could be very challenging and interesting at the same time. Another area of my interest is in Math. Math comes easier for me and I feel no matter what area of any professions I may go into, Math will be really important to know. Whatever the case, I love working with people in general and math is definitely one of my and I think it could be fun teaching it to students. I can envision myself in front of a class with eager eyes looking up to me to learn a new gained knowledge of how math can be applied to our daily lives. Most people feel that how is Algebra, Core Math, Calculus, Trigiometry, we never really use in our daily lives; but in reality we use them daily without knowing that we do. People who work not only in teaching, but in some fields like Chemist, Farming, Architecture, Wood workers (cabinet makers), and in any field that constitutes measuring of some sort. Teaching it would be a challenge of its own. That would mean I would have to be more organized than what I am. I am still leaving my clothes on the floor, and I may even have separate piles of clothing if I get rushed like; a pile of clean clothes, pile of only worn once clothing and can be worn again if sprayed, and then there is the must be washed, we all know those ones when the jeans stand on their own legs without help and the shirts smell strongly of the partying of the night before. But still even if organization could be the worst challenge, I know that all of my commitment and hard work would pay off with my studentââ¬â¢s achievements. Knowing a head of time that Math is one of the harder subjects to teach because it is the least interesting and sometimes really hard for some people, I know I would have to be sensitive to the children who do not have the same appreciation of Math as I do and make it as interesting as possible. How I would do that I am not sure as of yet, but I know I could achieve that goal. Knowing that math is all around us in our daily lives I will have to just grasp some of the ways they use it and incorporate it in the teaching for starters. What ever the case may be if I go into being a lawyer or teacher, I know that it will present its own challenges and with hard work and dedication I can achieve anything that I set my mind to. I love working with people, though I am a little shy at times, I know I can be a true asset to any field I venture into.

Musculosketal Systems and Physiology of Exercise
Musculosketal Systems and Physiology of Exercise The growth of the skeleton determines the growth and proportion of the body, the skeleton begins to form 6 weeks after fertilisation, bone growth goes through rapid growth through adolescents however genrally the skeleton does not stop growing up to the age of 25. Ossification is the formation of bone. The process of calcification ââ¬â the deposition of calcium salts-occurs during ossification, but it can also occur in other tissues. When calcification occurs in tissues other than bone, the result is a calcified tissue (calcified cartilage) that does not resemble bone. Two major forms of ossification exist: endochondral and intramembranous. In endochondral ossification, bone replaces existing cartilage. In intramembranous ossification, bone develops directly from mesenchyme or fibrous connective tissue. (fundamentals of A and P) Word count 119 The human skeleton consists of 206 bone. When together the skeletal system provides the framework which all other tissues and organs attach giving the body shape. The skeletal system is divided into two parts the axial which is made up of the spine, skull, ribs and sternum. The appendicularskeleton which is made up of the pelvis, arm and leg bones. The skeleton has 5 main functions. Shape- The shape of the bone structure changes as the body grows. The skeletal system determines the height and width of a person, body shape is heredity. The three main body shapes are ectomorphs (tall and thin), mesomorphs (short and muscular), endomorphs (apple shape) Support- the skeleton provides support to the body and keeps the internal organs in place. The vertebral column allows someone to stand erect. The pelvis and leg bones are strong enough to carry the weight of the whole body. Movement- The bones are held together by ligaments. Tendons attach the muscles to the bones. Combined the muscular and skeletal system carry out movement, when muscles contract bones move. Protection- The skeleton protects vital organs from damage. The skull houses the brain, while the vertebral column protects the spinal cord which controls all bodily functions through communication with the brain. The thorax and sternum protect the heart and lungs. (livestrong.com) Words 280 The Pivot joint- In a pivot joint, the rounded or pointed surface of one bone articulates with a ring formed partly by another bone and partly by a ligament. A pivot joint is monoaxial because it allows rotation around its own longitudinal axis only. Ball and socket- Consists of a bonelike surface of one bone fitting into a cuplike depression of another bone. Examples of functional ball and socket are the shoulders. Hinge Joint- The convex surface of one bone fits into the concave surface of another bone. Hinge joints are in the knee, elbow, ankle and interphalangeal joints. Ellipsoid Joint- The convex oval-shaped projection of one bone fits into the oval shaped depression of another bone. Examples are the wrist and metacarpophalangeal joints. Saddle Joint- The articular surface of one bone is saddle shaped and the articular surface of the other bone fits into the saddle as a rider would sit. The most common saddle joint is the trapezius Gliding Joint- The articulating surfaces of bones in a planar joint are flat or slightly curved. Some examples are the intertarsal joints between tarsal bones at the ankle joints. Sternocostal joints sternum ends of the costal cartilages at the tips of the second through seventh pairs of ribs. Gliding joints primarly permit side to side and back to back movements. (words 220) The bones at a synovial joint are covered by articular cartilage, which is typically hyaline cartilage and occasionally fibrocartilage. The cartilage covers the surface of the bones with a smooth surface but does not bind them together. Articular cartilage reduces friction between bones in the joint during movement and helps to absorb shock. Articular capsule- A sleeve like capsule l surrounds a synovial joint, encloses the synovial cavity, and unites the articulating bones. This is composed of two layers, an outer fibrous capsule and an inner synovial membrane. The FC, usually consists of dense, irregular connective tissue that attaches to the periosteal of the articulating bones. The flexibility of the FC permits considerable movement at a joints while tensile strength helps prevent bones from dislocating. The fibres of some FCââ¬â¢s are arranged in parrelel bundles that adapted for resisting strains (ligaments). The mechanical structure of ligaments helps to hold bones together in a SJ. The SM, is composed of areolar connective tissue. Synovail Fluid- The SM secretes SF, which forms a thin film over the surfaces within the articular capsule. This clear/yellow fluid consists of hydrochloric acid and interstitial fluid filtered from blood plasma. The functions of this fluid are reducing friction by lubricating the joint and supplying nutrients to and removing metabolic wastes within articular cartilage. (Grabowski and tortora 2003) (220 words) TAQ 2 Three layers of connective tissue are part of each muscle; epimysium, perimysium and endomysium. The entire muscle is surrounded by epimysium a dense layer of collagen fibres. The epimysium separates the muscle from surrounding tissues and organs. It is connected to the deep fascia, a dense connective tissue layer. The connective tissue fibres of the perimysium divide the skeletal muscle into a series of compartments, each containing a bundle of fibres called a fascicle. Possessing collagen and elastic fibres, the perimysium contains blood vessels and nerves that maintain blood flow and innervate the muscle fibres within the fascicles. Each fascicle receives branches of these blood vessels and nerves. At each end of the muscle, the collagen fibres of the perimysium, perimysium and endomysium come together to form a bundle known as the tendon or aponeurosis. Tendons and aponeurosis usually attach skeletal muscles to bones. Where they contact the bone, the collagen fibres extend into t he bone matrix, providing a firm attachment. Any contraction of the muscle will exert a pull on the attached bone. Muscle contraction huge quantities of energy. An extensive vascular network delivers the necessary oxygen and nutrients and carries away metabolic wastes generated by active skeletal muscles. (Martini2006) words 200 The primary cell types of tendons are the tenoblasts and tenocytes. Tenocytes are mature tendon cells that are found throughout the tendon structure, connected to collagen fibres. Tenocytes are mature tendon cells that are found throughout the tendon structure. Tendon tissue is the tissue which connects muscles to bones. Tendons are the connective tissues that transmit the mechanical force of muscle contraction to the bones; the tendon is firmly connected to muscle fibres at one end and components of the one at its other end. The tendons are the strongest amongst the soft tissues. They require great strength is necessary for withstanding the stresses generating muscular contraction. A tendon is composed of dense fibrous connective tissue made up primary fibres are bunched together into subfasicles. Multiple secondary fibre bundles form tertiary fibre bundles, groups of which in turn form the tendon unit. Primary, secondary and tertiary bundles are surrounded by a sheath of connective tissue (endotenon) which facilitates the gliding of bundles against one another during movement. (Britannica.com) (words 160) Skeletal muscle adaptations to extend to underwater time despite selective vasoconstriction include elevated myoglobin concentration, high acid buffering ability and high aerobic and anaerobic enzyme activities. Because cardiac muscle is perfused during dives, it will rely less heavily on MB and anaerobic pathways to support contractile activity even before birth, it may be more physiolically mature at birth and develop faster than skeletal muscles. (jeb.biologists.org) The energy for muscle contraction comes from ATP, which in turn comes from the metabolism of glucose and fatty acids. But not much ATP is stored in the muscles that just a few twitches could quickly exhaust the supply. Creatine phosphate cannot be used directly to power muscle contraction but phosphate can transfer its phosphate group to ADP to form ATP: Creatine phosphate + ADP += creatine + ATP. Two types of skeletal muscle Red (Slow twitch) White (Fast twitch). Red has a rich blood supply, numerous mitochondria and myglobin, that forms a loose combination with oxygen and stores it in the muscle. Although it contracts rather slowly it is capable of long term activity without fatigue. White Muscle has a limited blood supply, few mitochondria and a low myoglobin content. It depends entirely on anaerobic breakdown of glycogen for its energy supply is capable of very strong rapid contractions for a short period of time. Because these fibres have fewer mitochondria and capillaries than red fibres, their ability to resynthesize ATP through oxidative phosphorylation is limited and they fatigue rapidly. Muscle fibre types also differ between the sexes. Women tend to have more red fibres and less white fibres so a female will have less strength than a male but has more endurance. Men with more white fibre depend more on storing carbohydrate for fuel, therefore they have less endurance. Smooth muscle has some differences to skeletal muscles they are a pplied slowly and smoothly- contractions of the digestive system can occasionally rapid. In smooth muscle Ca ions activate the myosin, through two intermediate enzymes before the ATP becomes involved. Although smooth muscle contraction is slow it is efficient it uses 10% of the ATP required by skeletal muscle to produce the same strength contraction. Cardiac muscle is unique to the heart. It is able to beat incessantly because it never maintains a contraction. It contracts and promptly relaxes and the relaxation period is twice as long as its contraction period. The relaxation periods and contraction periods are strictly programmed; the muscle rests, then it must contract before it can rest again. Cardiac muscle is unlike smooth or skeletal muscle, it cannot rely on anaerobic metabolic pathways to provide its energy; it must never fail to get all the oxygen it needs. Cardiac muscle is the muscle in our bodies that is unable, except in disease states, to achieve a state of sustained contraction. (biog1445.org) (Martini 2006) Words 506 TAQ 3 The Impact of exercise on the Cardiovascular system: At rest the average cardiac output is 5.8 litres per minute, this changes significantly during exercise, the pattern of blood distribution changes. Light exercise: before you begin to exercise, the heart rate will increases slightly because of the rise in sympathetic activity. Extensive vasodilation occurs as the rate of oxygen consumption in skeletal muscles increases. Peripheral resistance drops, the blood flow through the capillaries increases and blood enters the venous system at a fast rate. The venus return increases as skeletal muscle contractions squeeze blood along the peripheral veins and increased breathing rate pulls blood into the venae cavae via respiratory pump. Cardiac output rises, primarily in response to the rise Respiratory System As the cardiac output rises the blood flow to the lungs ( pulmonary perfusion) increases. The oxygen diffusing capacity a measurement of the rate the avelor air into the blood increases during maximal exercise because more pulmonary capillaries become perfused. There becomes a greater surface area available for diffusion of oxygen into the pulmonary blood capillaries. During vigorous exercise, oxygen consumption and pulmonary ventilation both increase dramatically. With moderate exercise the increase is due to an increase in the depth of ventilation rather than the increased breathing rate. The abrupt increase in ventilation at the beginning of exercise is due to neural changes that send impulses to inspiratory area. The gradual increase in ventilation is due to chemical and physical changes in the blood stream Decreased hypophosphite due to increased oxygen Slightly increased Pc02 due to CO2 production contracting muscle fibres Increased temperature, due to the release of more heat as more oxygen is utilized. Smoking lowers respiratory effiency during exercise even with moderate exercise because several factors effect the respiratory system Nicotine constricts terminal bronchioles Carbon monoxide binds to haemoglobin reducing oxygen carrying capability Irritants in smoke cause muscus secretion to increase Muscular People with a higher proportion of fast glycolytic fibres often participate in activities which require periods of intense activity such as weight lifting. People with higher percentages of slow oxidative fibres are better at activities that require endurance ( long distance running). The total number of skeletal muscle fibres do not increase, the characteristics can alter to some extent. Aerobic exercises cause gradual transformation of FG fibres into FOG fibres. The transformed muscle fibres show slight increases in diameter. Exercise require great strengths for short periods of time to produce an increase in the size and strength of FG fibres. The increase is due to increased synthesis of thick and thin filaments. The result of muscle enlargement is evidence by the buldging muslces of body builders. Anabolic steroids are hormones similar to testosterone which increase muscles and strength during exercise. The large doses required have damging effects such as aggression, heart dise ase, kidney damage and stunted growth. Skeleton Bones have the ability to alter their strength in response to changes in mechanical stress. When placed under stress the bone tissue adapts by becoming stronger through increased deposition of mineral salts and production of collagen fibres. Another effect of stress is to increase the production of calcitonin. Without mechanical stress, the bones are unable to remodel normally because bone resorption outstrips bone formation. Removal mechanical stress weakens the bones through demineralisation and decreased collagen fibres. The most common of mechanical stress on the bones is from the the pull of skeletal muscles and the pull of gravity. The bones of an athletic person become thicker and stronger, weight bearing activities help build and retain bone mass. Astronauts and people which have fractured bones can lose up to 1% of bone mass per week. Words 560 (tortora grabowski 2003) TAQ 4 Osteoarthritis This is a degenerative non- inflammatory disease where over a period of time the cartilage is gradually lost. This will result in painful and restricted movement of the affected joints. This disease is a result of aging, irritation of the joints. This disease is the cause of disability in the elderly. The articular cartilage becomes thinner because its renewal does not keep in unison with its repair. Eventually the bony articular surfaces come in contact and the bones beings to degenerate. Some abnormal bone repair does take place and the articular surfaces become misshapen. Chronic inflammation develops with the effusion into the joints, due to the irritation caused by the tissue debris not removed by phagocytes. In some cases there is abnormal outgrowth of the cartilage at the edges of the bones which becomes ossified. Primary Osteoarthritis- Is the most common type, the cause of this disease is unknown. The changes may be due to acceleration of the normal aging process within the joints which have had excessive use over the years due to plenty of physical activity. This usually begins to develop in the late stage of middle age and affects large weight bearing joints; the hips, knees, cervical and lumbar spine. In most cases of primary osteoarthritis only affects one joint. Secondary osteoarthritis- This tends to occur in the joints where the cartilage has already been damaged due to Congential deformity of bones such as dislocation Trauma, intracapsular fracture of the bone and injury to intracapsuel structures. Other conditions, inflammatory diseases, haemophilia following repeated haemorrhages into the joints, peripheral nerve lesions, gout, acromegaly, diabetic neuropathy. Osteoarthritis of the spine This condition is more common within the elderly. Degenerative changes cause narrowing of intervertebral discs and osteophytes may develop around the margins of joints of the vertebral column, commonly in the cervical region. This may cause damage to the nervous system, varying from compression of the individual spinal nerves to spinal cord injury ( the main cause of paralysis). (340) (Grabowski and tortora 2003) Cruciate Knee This is where the ligament in the knee is torn which may result in reconstructive surgery. The anterior cruciate ligament is a tough band of tissue joining the thigh bone to the shin bone at the knee joint. (nhs.com). This condition tends to affect people which are more athletic. The cruciate ligaments are found inside the knee joint. They cross each other to form an x with the anterior cruciate ligament in front and the posterior cruciate ligament in the back and forth motion of the knee. The anterior cruciate ligament runs diagonally in the middle of the knee, it prevents the tibia from sliding out in front of the femur and this provides rotational stability for the knee. There are 3 different grades of sprains which occur to the knee Grade 1 sprain is where the ligament has been slightly stretched and the knee is still stable. This will result in discomfort whilst walking and inability to participate in strenuous activity. Grade 2 This stretches the ligament to the point where it becomes loose. This is often referred to as a partial tear. Grade 3 This is referred to as a complete tear of the ligament. The ligament has been split in two pieces and the knee joint is unstable. The cruciate anterior is often injured by stopping suddenly, changing direction instantly, slowing down whilst running, landing from jumping incorrectly, direct collisionââ¬â¢s in contacts sports such as football and rugby. When the anterior cruciate is injured often the patient will hear a popping sound and will feel their knee giving way underneath them. The most common symptoms are; The knee will swell within 24 hours. The pain and swelling may resolve naturally. However if the patient choses to attempt returning back to sports they may cause further damage to the meniscus of the knee. Loss of a range of movement in the knee Tenderness along the joint line When a person does not have the adequate muscles strength coordination or balance to quickly react to the demands of sports there is an increased risk for a serious knee injury. Glute weakness and instability lead to excessive strain being placed on the ALC.
