A Comparison of Hamlet and Mcmurphy in One Flew over the...

A Comparison of Hamlet and McMurphy in One Flew Over the Cuckoos Nest It is suggested that in modern literature, the true element of tragedy is not captured because the protagonist is often of the same social status as the audience, and therefor, his downfall is not tragic. This opinion, I find, takes little consideration of the times in which we live. Indeed, most modern plays and literature are not about monarchs and the main character is often equal to the common person; this, however, does not mean the plot is any less miserable nor the outcome any less wretched. The first work I have chosen proves this fact. One Flew Over the Cuckoos Nest, a first novel by Ken Kesey published in 1962, is a contemporary tragedy describing†¦show more content†¦He was the logger again, the swaggering gambler, the big redheaded brawling Irishman, the cowboy out of the TV set walking to me a dare. The common theme in each plot is a rise against tyranny in defense of ones honor to defeat the evil repressor. Despite their different methods, it was the eventuality of revenge that drove Hamlet and McMurphy onward to the brutal end of it all. Although McMurphy disguises it with ignorance and Hamlet flaunts it in his wit, another striking resemblance is the aptitude of these two characters. A consequential parallel between them is also their use of this intellect to set and trap the other characters. McMurphy does this with interest in personal gain, as he often maneuvers the other patients into betting against him when unbeknownst to them, the odds are in McMurphys favor: He let the odds stack up, and sucked them in deeper and deeper till he had five to one on a sure thing from every man of them, some of them betting up to twenty dollars. Hamlet as well manipulates for personal gain, though his is not monetary. He plots to fulfill he need for absolute certainty; his, is a plot for information. Certainly, the best example of this, is the influence Hamlet uses on the play staged by the traveling theater company. His insistence the players perform The Murder of Gonzago, a show that eerily shadows the method used by Claudius himself

INTRODUCTION The developments taking place in information and communication technology are increasing competition in financial institutions worldwide. Development of electronic distribution channels in financial industry has completely transformed the traditional bank–customer relationship in recent years. It has reduced personal contacts between the service providers and the customers (Barnes and Howlett, 1998). The scenario is further changed with increased competition among banks and non-bank financial institutions (Zineldin, 1996). Thus an enhanced understanding of why some people adopt one distributional channel and others do not, alongside an identification of the factors that may influence this decision is vital to investigate (Patricio, 2003). Thus, the deployment of advanced technologies is essential to achieve a competitive edge. In the world of banking, the development of information technology has an enormous effect on development of more flexible payments methods and more-user friendly banking services. Recently, the banking industry was highly affected by the technology evolution that transformed the way banks deliver their services, using technologies such as automated teller machines, phones, the Internet, credit cards, and electronic cash. In line with global trends, electronic banking in Pakistan has been undergoing many changes. Electronic banking is a term for the process by which a customer may perform banking transactions electronically without visiting a brick-and-mortar institution. Electronic banking refers to systems that enable bank customers to access accounts and general information on bank products and services through a personal computer (PC) or other intelligent device. There are many benefits of e-banking as it provides easy way to monitor an account, we can shop, pay bills, buy items at auction, and transfer money from anywhere at any time, it reduces costs, it saves time, and vice versa. Objectives This study focuses on awareness and adoption of electronic banking in Pakistan. Our objectives of this research were to: 1. Check awareness of electronic banking in Pakistan. 2. Check why people are not aware of electronic banking. 3. Know if the people are aware of electronic banking then to how much extent. 4. Check whether banks of Pakistan are providing electronic banking or not. 5. To find the critical attributes that customers expect important while using electronic banking. 6. To find the key variables that affect customers’ evaluations towards risk associated with electronic banking. 7. To understand the relationship between demographic characteristics of customers and their perceptions towards electronic banking. 8. To present results and implications which are insightful to researchers and banks interested in electronic banking. This research is important because it tells bankers that how much people in Pakistan are aware of and adopt the electronic banking and to how much extend. It also tells them to improve their e-banking services in Pakistan. Electronic banking in Pakistan State-owned banks dominated the Pakistani financial market before 1990. The government introduced economic liberalization policies in 1991 when two smaller banks, Muslim Commercial Bank and Allied Bank were privatized. Since then, the government continuously advocated the privatization of existing state-owned enterprises and encouraged the private and foreign banks to setup their businesses in the country. Recent acquisition of locally owned Union Bank by Standard Chartered Bank indicates foreign interest in domestic financial market. According to State Bank of Pakistan (SBP) annual report (2005), there were 35 commercial banks, including 16 private banks (with 797 branches), 11 foreign banks (with 82 branches), 4 privatized banks (with 4,141 branches) and 4 public banks (with 1,543 branches), respectively. Electronic banking is an innovation in the series of technological wonders. Automated teller machine (ATM), telephone banking, internet banking, credit cards and debit cards, etc. have emerged as effective delivery channels for traditional banking products. In Pakistan, foreign banks took a lead by introducing ATM and credit cards in mid-1990s followed by domestic banks in late 1990s. Annual Report of SBP (2003, p. 110) explained this delay in electronic banking largely by regulatory hurdles, higher startup costs, an ongoing banking sectors reforms and lack of technical skills. The government also introduced Electronic Transaction Ordinance in 2002. This ordinance provides legal recognition to digital signatures and documentation. Thus reducing the risks associated with the use of electronic medium of business. At present, almost all commercial banks in Pakistan have setup their ATM networks, issuing debit and credit cards and have joined one of the two operating ATM Switch Networks. According to Kolachi (2006) Pakistani banks provide the following online banking services and products. 1. Enquiry, account statement enquiry, account balance enquiry, check statement enquiry, fixed deposit enquiry 2. Payment, funds transfer, credit card payments, direct payments, utility bills payments 3. Request, checkbook request, stop payment request, demand draft request, new fixed deposit request 4. Download, customer profile, statement download, other information and guidelines downloads. 4 Literature review Consumers’ perceptions towards adoption of electronic banking have attracted many researchers in recent years. Thornton and White (2001) who compared seven distribution electronic channels available for banks in US concluded that customers’ orientation such as convenience, service, technology change, knowledge about computing and availability of internet affected the usage of different channels. According to Hagel and Hewlin (1997) the Internet banking became very attractive to customers and lots of banks because the technology is being accepted by them and they can now understand and have information about the complex products. Nowadays banks are also facing a lot of competition and need a high market share and provide better services to its customers so that they can attract the new customers and old customers do not try to leave them. Howcroft et al. 2002) found that the most important factors that have encouraged consumers to use online banking are lower fees followed by reducing paper work and human error which subsequently minimize the human disputes (Kiang et al. , 2000). Byers and Lederer, (2001 ) concluded that it was changing consumer attitudes rather than bank cost structures that determines the changes in distribution channels; they added that virtual banks can only be profitable when the segment that prefers electronic media is approximately twice the size of th e segment preferring street banks. Decrease in percentage of customers visiting banks with an increase in alternative channels of distribution will also minimize the queues in branches (Thornton and White, 2001). Internet banking increases power of the customers to make price comparison across suppliers quickly and easily, which subsequently pushes the price and margins downwards (Devlin, 1995). Although, electronic banking provides many opportunities for the banks, it is also the case that the current banking services provided through Internet are limited due to security concerns, complexity and technological problems (Sathye, 1999: Mols, 1999). Risks associated to electronic banking Although internet provides many opportunities for banks but it is the case that current banking services through internet are limited due to security concerns, complexity and technological problems (Mols, 1999; Sathye, 1999). Hewer and Howcroft (1999) referred the term trust to measure a risk. While, Suganthi et al. (2001) viewed risk in context of security concerns and risk in context of trust in one’s bank. Finally, a number of studies also found trust and perceived risks have a significant positive influence on ommitment (Bhattacherjee, 2002; Mukherjee and Nath, 2003) and ultimately leads towards overall satisfaction (Rexha et al. , 2003). Reputation of a service provider is another important factor affecting trust. Doney and Cannon (1997) defined reputation as the extent to which customers believe a supplier or service provider is honest and concern about its customers. Tyler and Stanley (1999) argued that banks can build close and lo ng-lasting relationship with customers only if trust, commitment, honesty and cooperation are developed between them. Nancy et al. 2001) study found that customers’ complaint about computer logon time which are usually longer than making a telephone call. Further, the respondents felt that they have to check and recheck the forms filled online, as they are worried about making mistakes. Frequent slow response time and delay of service delivery causes customers to be unsure about the completion of a transaction (Jun and Cai, 2001). Min and Galle (1999) found crashes in operating systems and disruption of information access as common factors related to unwillingness to use internet channels for commerce. Liao and Cheung (2002) found that individual expectations regarding accuracy, security, transaction speed, user friendliness, user involvement and convenience are the most important attributes in the perceived usefulness of internet-based e-retail banking. Confidentiality of consumer data is another important concern in adoption of online banking (Gerrad and Cunningham, 2003). Customers fear about someone’s unlimited access to personal financial information. White and Nteli (2004) focused on why the internet usage has not been increased in UK as compared to internet usage for banking purposes? Results found that the customers still have concerns about the security and safety aspects of the internet. Lack of internet accessibility and a provision of documentary evidence for all transactions are found important hurdles in the development of electronic banking in Thailand (Jaruwachirathanakul and Fink, 2005). Laforet and Li (2005) found that habit of carrying cash, less accessibility of internet and documentary proof of financial transaction as important hurdles in adoption, in case of China. Lack of specific laws to govern internet banking is another important concern for users. It covers issues such as unfair and deceptive trade practice by supplier, unauthorized access by hackers. Larpsiri et al. (2002) argued that it is not clear whether electronic documents and records are acceptable as sufficient evidence of transactions. Another issue is the jurisdiction of the courts and dispute resolution procedures in case of using internet for commercial purpose. Dispute can arise from many issues. For instance, websites is not branch of the bank. It is difficult for the court to define location of branch and decide whether they have jurisdiction (Rotchanakitumnuai and Speece, 2003). Other risks associated to electronic banking are job losses, lack of opportunities to socialize and development of lazy society were mentioned by (Black et al. , 2001). Demographic factors Gender alone is not a significant factor, affecting adoption of technology in general (Gefen and Straub, 1997). However, Kolodinsk et al. (2004) found that married couples are more likely to adopt the new technology than either single males or females. Research has also linked age and adoption of technology, as young people are more likely to adopt technology (Lee et al. , 2002). Maturity in population in terms of knowledge, confidence and comfort in computer usage also increase influence towards online banking (Karjaluoto et al. , 2002). Increase in income and education have found positive effects on adoption (Lockett and Littler, 1997; Sarel and Marmorstein, 2003). Mattilia et al. (2003) indicated that young, educated and wealthy consumers are most likely to adopt internet banking in Finland. Mature customers prefer personal service and a printed receipt of their transactions. Mature customers also perceive internet banking to be more costly than paying bills over the counter. Methodology The study was conducted in Lahore city which is the second largest city of Pakistan and represents almost 20% of all branches network. Branches for survey were selected on convenience basis but after the permission of respective branch managers. Survey covered both residential and commercial areas. In this research data is conducted by using questionnaire as a data collection instrument, in which questions were asked starting from their command on computer and internet usage, following with the awareness of electronic banking and its types, about the benefits of e-banking and then some questions regarding their bank services and the security provide by these banks.

Chaucers Attitude Towards Wealth Essays - The Canterbury Tales

Chaucer's Attitude Towards Wealth Essays - The Canterbury Tales Chaucer's Attitude Towards Wealth In the masterpiece, The Canterbury Tales, Geoffrey Chaucer described his characters by classification. Chaucer describes the characters wealth as an impression on the character, good or bad. Chaucers attitude helped to create feelings for the characters that were described throughout the work. Chaucer attitude towards the guildsmens showy wealth was opposing of their real character. For example, they strongly represented one impressive guild-fraternity (13) with showy clothes and admirable gear that they wore. The guildsmen had a lot of money and wanted to show it off to everyone that they saw. Also, their knives had only the best metal put on them, and wrought with purest silver (13) which only brings attention to their showy dress. The guildsmen thought that the better you dressed the richer you are. Chaucer was impressed with their league of members and how each one helped the other out. Chaucer shows the Wife of Bath as being well traveled and well known throughout the town. For example, She dressed as though she her hose were of the finest scarlet red, and her shoes were soft and new. (15) Being nicely dressed made up for her lack of attraction. She also had pride in her self about her skills as a seamstress and her self as a person. When she walked through town it was as though she was putting on a pageant for impressing men. In addition, shed been to Rome and also to Boulogne, St James of Compostella and Cologne. (15) She had freedom to travel and wasnt always worried about her responsibilities. Having the independence to travel brought her new experiences in life. Chaucer thought that the Wife of Bath was a renowned seamstress that enjoyed a lot of friendships and adventure. Chaucers attitude toward the plowmans dedication for the good of the church was very praiseworthy. First off, the plowman paid his tithes in full when they were due and always was unselfish of his giving. (17) Even with the grunt job he had, the plowman worked for the betterment of the church. Also, being an honest worker, good and true, (17) he worked hard for every penny he earned. The plowman never slacked when he worked and never asked for more than should be earned. The plowman did not waste his money on himself instead he gave it to the church for love of Christ. (17) What is the right way to show off your wealth? Each person showed their wealth in different fashions equal to their place in society. Chaucer showed through his attitude that some characters show of wealth was a better choice compared to others, but each character was proud of what they had accomplished.

Homework Assignment Example | Topics and Well Written Essays - 250 words - 55

Homework - Assignment Example But on the negative side, there are environmental worries such as a disastrous oil spill (the pipeline could break due to a number of factors such as acts of sabotage, an earthquake, an explosion, an accident, etc.) which could destroy pristine lands along the route, especially along the sensitive Sand Hills region of north-central Nebraska. My stance is the pipeline project should be approved because environmental concerns were being adequately addressed by the project proponents. This is because more oil supplies will bring down the cost of oil and benefit millions of American consumers. This is similar to what consumers enjoy today regarding the use of fracking (hydraulic fracturing) technology which made natural gas easier to access, more abundant and considerably cheaper too. The project passed the Senate (by a vote of 62-36) and the U.S. Congress ( or Lower House) approved it on February 11, 2015 (by vote of 270-152). Keystone was delayed due to Democratic control of Congress as Democrats opposed it but the recent mid-term elections shifted control of Congress to the Republicans who support it. President Obama is expected to veto it as he is a Democrat but neither the Senate nor the House has enough votes to overcome an expected presidential veto as of now. If the Republicans win the next presidential election, they will certainly approve the Keystone XL Pipeline Project because it favors Big Business. They are expected to revive this big oil project in the next Republican administration if their candidate wins whoever it will be among the various possible frontrunners such as Jeb Bush, Mitt Romney, Scott Walker, Paul Rand, and Marco Rubio. The Senate is now in Republican control (majority of senators are now Republican). What this all boils down is a s tark choice between conservation (wise use of resources) and preservation (no

Democracy and Religion in Developing Countries Essay

Democracy and Religion in Developing Countries - Essay Example In the Muslim world, particularly developing countries issues concerning political democracy are raised with special force because of the strength of the Islamic resurgence and the intensity of the demands in recent years which demand better political processes. Before examining the application of democracy in Islamic countries, there is a need to analyze the significance of Islam in politics. Islamic politics according to modern Islamic movements and what history tells us is a combination of religion and politics for the reason that medieval Islamic civilization of the Umayyads and the Abbasids followed non-state structures based on the grounds of religious faith and action (Esposito & Voll: 4). This indicates that the true implication of democracy in the Muslim era was followed by the belief that the most pious person among the society was supposed to be selected by civilians as well as by his followers. The current political culture of liberal secular societies never concern about God and never weighs God's approval or disapproval of their policies or behaviour. For this reason one can see that even religious political struggles and negotiations differ a lot when compared to those of the past. This clearly indicates that today's liberal democratic governments pursue people's happiness to the exclusion of God's approval (Sadri & Sadri: 122). Democratic Political Systems The concept of democracy followed in Islamic countries encompasses Islamic activist movements that challenge government while supporting others. What usually happens in this era is that in the political interests of Islamic revivalist groups, revolutionary opposition takes place which leads them either to ruling governments, or such movements may participate in the ruling political system as opposition movements. Many times it is seen that such religious movements are based as they are crucial part of the government or are themselves the ruling force in the political system. Such a perspective of democracy is based on a broad spectrum that gives us an overview of different situations within which Islamic democratization exists. Therefore such situations are: (1) revolutionary democracy to the ruling political government (2) legal or cooperating democracy that works within the boundaries of political system (3) active participation as a democratic government alliance which works wit h other political forces and (4) the system that controls and leads the existing political system. The above situations as practiced by most of the Islamic countries shapes the nature of emerging democratic ideals in the Islamic world as well as the developing and influenced new political orders in Islam. Democracy in the Middle East As far as Islamic law and order is concerned, it is severely implemented in the region except for the positive peace in the Middle East. Countries like Iraq, Iran and Israel are pervaded with armed conflicts in various types and forms like regional conflicts, resource wars, separatist and nationalist conflicts and irredentist conflicts. However some countries are influenced by other ethnic, religious and tribal struggles to the extent where their democratic power is heavily influenced under revolutionary and fundamentalist struggles. The peoples and governments throughout the Middle East are thus confronting pro-democracy anti-colonial struggles. Middle Eastern democratic trend follows violent conflicts and does not fulfil the criteria of positive peace in the region which is the utmost ground for building a democratic

King Arthur Vs Beowulf English Literature Essay

King Arthur Vs Beowulf English Literature Essay Numerous stories about numerous heroes have been told and retold. All of these heroes do different things and all of them have different sets of qualities which make them heroic. Due to the fact that there are only so many heroic adventures and qualities, most are shared in part with at least one other hero. Such is the case between the great hero, Beowulf, from the epic poem Beowulf, and King Arthur from the story of Morte Darthur. These great heroes have strong similarities and a great deal of differences. Once their similarities have been compared I find it evident that Beowulf is the greater hero of the two. True heroes do good things for good people. Such is the case in the story of Beowulf. Beowulf leaves his homeland to help the Danish people rid themselves of the man eating monster, Grendel. This heroic quality is also evident in Morte Darthur, where Arthur consciously rides into a battle in order to rid his people of an evil knight who would not allow others to pass. Both heroes are displaying their concern for others by risking their own lives in battle for the greater good. In the same aspect they are also striving to gain the love and respect of the people they protect In order to obtain maximum respect in each conflict, both Beowulf and Arthur enter into battle somewhat alone. Beowulf specifically asks, That he, alone and with the help of his men, may purge all evil from the hall. His request is granted by Hrothgar, King of the Danes, so he and his man enter into the battle themselves so that when Grendel is defeated, the glory, love and respect belong solely to Beowulf and his men. Arthur does the same, he met with his man and his horse, and so mounted up and dressed his shield and took his spear, and bade his chamberlain tarry there till he came again. Although Arthur begins his journey alone he does meet up with Merlin, the court magician and faithful companion, who accompanies him. Much like Beowulf, Arthur gains great respect and praise from his people by fighting alone, even though it is not necessarily the smartest thing to do. The characteristic of being fearless when faced with death is often a trait of heroes because it is associated with courage and strength. King Arthur and Beowulf are not afraid to die, thus showing their courage to their adversaries and followers. When Arthur is faced with death he declares, welcome be it when it cometh, but to yield me unto thee as cowardly I had liefer die than to be so shamed. Simply put, he would rather die than admit to defeat and being cowardly. Beowulf feels much the same way about death. He illustrates this by showing no fear for his own life but instead expressing concern for the honor of King Higlac by asking that, if death does take him, send the hammered mail of his armor to Higlac. In sending his King his armor it recommits himself to his country and lets his King be reminded of his bravery every time he looks upon it. That is the extent, from what I was able to interpret, of which Beowulf and King Arthur are similar. Beowulf has way more confidence in his fighting ability then Arthur has in his. This is evident in the fact that Beowulf fights Grendel unarmed and says my hands alone shall fight for me, struggle for life. His reasoning behind this is that Grendel is the scorn of men and is so great that he needs no weapons and fears none so nor will he (Beowulf). Facing Grendel unarmed shows that he is brave and, more importantly, unafraid to fight on an equal level with Grendel. Since Grendel is going to fight without the use of weapons, Beowulf creates equality and therefore earns himself even more respect by doing the same. The less confident King Arthur on the other hand fights only with weapons. Once his wounds were amended his first thought was, I have no sword, followed by the task of finding him one. This demonstrates Arthurs relative weakness in his dependence on weapons when held in comparison to Beowulfs willingness to fight a creature greater than himself with nothing but his bare hands. It is this that I feel best illustrates Beowulfs greatness. Beowulf is indeed the greater hero as the help he received from his men was minimal, not by fault of his men but by the fact that Grendel, had bewitched all mens weapons, laid spells that blunted every mortal mans blade, Since Beowulfs men could give him no help due to Grendels spell, he had to defeat the monster by himself, with his bare hands. Arthur on the other hand lost his battle. First Arthur lost a jousting match and then he lost on the ground when the knight smote King Arthurs sword in two pieces. Merlin had to come to his rescue at this point and, by using his magic, he put the knight to sleep for a period of three hours. So to recap, Beowulf defeated a monster with no aid from his companions and Arthur could not defeat a knight and instead had to rely on the aid of magic from Merlin. Even though both King Arthur and Beowulf are great heroes, I think that Beowulf emerges as the greater of the two. He does this through his successful feats, not through his heroic qualities. For when comparing the heroic qualities of Arthur and Beowulf they come up pretty even. Both demonstrate a great love for others as they both try to do good things for other people. Their differences in heroism might be due to the fact that Arthur is a young hero in comparison to Beowulf who is an experienced hero. Either way they, like most heroes, have similarities and differences which make them the characters that they are.

Violence :: essays research papers

Media Violence   Ã‚  Ã‚  Ã‚  Ã‚   Psychological research has shown three major effects of seeing violence on television. The three major effects that many parents world wide fear are children may become More aggressive and behave in harmful or hazardous to others. Be less sensitive to the pain and suffering of others, and children may be more fearful of the world around them. Violent programs on television lead to aggressive behavior by children and teenagers who watch those programs. Children begin watching television at an early age, sometimes as early as six months, and are ardent viewers by the time they are two or three years old. The general pattern of viewing is one of the steady rise in the number of hours viewed from early childhood to preadolescence and then a sharp drop in viewing during the adolescent years. According to audience rating surveys, the typical American household has the television set on for more than seven hours each day, and children age 2 to 11 spend an average of 28 hours per week viewing. There is a growing concern in this country about teenage violence and how it is connected to the violence seen on the television. The impressionable youth of America somehow fall victim to spending many hours a day watching television and is exposed to violence. Studies show that the average child has witnessed eight thousand murders before they actually finished elementary school. Most of the shows that the younger generations watch contain some vi olence. Several years ago when Power Rangers was first Broadcasted, it had a great effect on the younger population concerning violence. Many children began trying to imitate these so called â€Å"Heroes.† Three out five children, eight-six percent males had a tendency to want to rough house with the other children and or had outbursts of violence. Of course, conditions in society, does not make it easy to pull a child away from the television. Parents work and most families cannot afford to have a parent stay home and watch the children. This situation is understandable and does not necessarily mean that parents do not care for their children. Parents regardless of the situation should try to be as involved as much as possible. Parents should take time out to speak to their children about certain programs they might come across while viewing the television. Parents should also view programs with their children so they can get a better understanding of what their children see when they turn on the television.

Paul Lutus Advertising Essay

In his article entitled Consumer Angst written in 2007, Paul Lutus claimed that â€Å"No matter how true any single advertisement is, modern advertising, taken as a whole, tells a lie — that you need the thing being advertised. † To explain his point, Paul Lutus further claims that valuable consumer goods need not be advertised because it is a necessity by itself and no promotion is needed for it to attract and obtain sales. Moreover, he explained that the quality of the product should speak for itself and there is no need to â€Å"waste company’s money asserting the obvious†. In his above-mentioned arguments, Paul Lutus obviously focuses only on one aspect of advertising which is to sell. He missed to appreciate the other function of advertising which is to inform. Advertising, as defined by Wikipedia. org, â€Å"is the form of communication whose purpose is to inform potential customers about products and services and how to obtain and use them†. The primary purpose of advertising is to create public awareness about a certain product or service that is being advertised. It aims to communicate to the intended audience that such a product or service exists. As Taflinger (1996) claims â€Å"the basic purpose of advertising is to identify and differentiate one product from another in order to persuade the consumer to buy that product in preference to another. † Advertising is usually used to create a unique image that will be identified to a product or service. The message that is being communicated usually highlights the best features of the product – its uniqueness, usability, best characteristics, etc. – that will customer’s attention to it. After providing information on the product or service features, advertising’s goal is to entice customers to try out the product. It is therefore safe to claim that the end-goal of any advertisement is to generate sales in terms of product or service. However, while it is true that every advertising campaign is aimed at generating revenue for the brand that is being advertised, it is not proper to claim that all advertisements are lies. Even premium brands such as Nike, Armani, Prada and others do advertise their products. These brands are sought after and have all proven to be of good quality. But these brands still invest on advertisement. Advertising has become an important part of today’s business. With new products sprouting like mushrooms everyday, competition has become stiff and advertising has taken a big role in allowing the product or service to compete in the market. In his article entitled â€Å"Educating the Consumer about Advertising: Some Issues† Stephen Gotlieb (1991) explains that advertising â€Å"promotes competition among producers of products and services, keeps prices low through the development of mass markets, encourages store owners to stock a variety of items, supports free expression by funding media sources, and spurs invention†. The more you are seen and understood by your customers, the bigger chance you have to stay in the mainstream. It is therefore important to get you message through, so that your product or service gets noticed. Or else, your offer will just perish. Also, with the competition getting tighter, advertisers today cannot afford to rely on false claims for their products of services. With a lot of other options available in the market, a single wrong claim will trigger the customer to try out other product. It is the role of advertising to entice customers and encourage them to try out the product. Once the customer is convinced with the advertising claim and decides to avail the product or service, it is now the role of the product to prove itself and embody what is being stated in the advertising claim. It is therefore crucial to communicate the message that best embodies the product. Once advertised, the product or service is already exposed to t he public eye and scrutiny. Unless the customer has already tried out the product or service, their perception of the product will depend on the advertisement. It will either make or break the future of the product or service depending on how you position the message about the product. Therefore, while an advertisement is typically used to create or alter the consumer’s perception of a product and induce them into buying it, it cannot be said that it is Always  a lie. For obvious reasons, advertisements only highlight the good side of the products or services. We cannot blame the advertisers to do this. While they are obviously banking on the good side of their offer, we cannot accuse them of telling us a lie. The beauty of advertising is it gives the customers the chance to evaluate the competing products or services even before purchasing it through the product claims.

Poverty in the Tudor Period essays

Poverty in the Tudor Period essays What were the major problems of the poor in the period 1471 1626 and how were they alleviated? There was a massive increase in poverty and the problems faced by the poor in the period 1471 1626, this was due to a number of interdependable social, economic, and monarchical changes throughout the period. There was a high rise in birth rate, causing the population to double between the reigns of Henry VII and Elizabeth I. Along with this, unemployment rose, and rapid price inflation caused the problems of the poor to increase. In addition there was a famine in the countryside that averaged out at once every four years. During the 1530s, Henry VIII's reformation and dissolution of monasteries resulted in, among other things, much Church land being put on the market, thousands of ex-monks being released into society and the caused the end of monastic charity and welfare. Also the reduction of people living in service was reduced causing more problems for the poor, as there was a reduction of jobs that showed a way out of the poverty cycle. There were solutions to these problems, however solutions depended on the type of poor, as the government had defined 3 types, the visible poor, the Able-bodied poor and beggars known as Vagabonds. The Government passed various laws from 1532 to 1601 to help the poor, and prevent vagabonds. Charities also provided help for the poor of the period, thus alleviating the problems of the poor to an extent. There were many social problems that caused poverty to worsen during the period 1471 1626. There was a massive population increased, the population had been increasing since at least the1520s, possibly 1470s, with a high birth rate fueling the rise. However the rise in population was not solely enough to cause the mass poverty of the period. In addition to the growing population increasing, there was bad harvests, roughly once every four years, causing p...

Popular music and thinking errors

Popular music and thinking errors The contemporary society is full of things that can, possibly, affect the minds of young people adversely. Whatever these young people listen to, watch on television or in videos or even hear from others has the possibility of influencing their lives for the better or for the worse. One such phenomenon that has greatly polluted the minds of young people is music. Advertising We will write a custom essay sample on Popular music and thinking errors specifically for you for only $16.05 $11/page Learn More Young people are fond of listening to controversial music that can adversely affect their minds and even lead to depression in them. Being young, I am no exception. My favourite genre of music is rock which is mostly filled with pessimistic and angry messages in its lyrics. This paper is an exploration of how the lyrics in popular music may cause thinking errors in people and, possibly, lead to depression. Rock is one kind of music in which most songs portray the same message. The message in the lyrics of rock songs is mostly that life is not worth living with the lyrics filled with numerous pessimistic and angry lines. Take for example the rock song I Hate Everything About You that is done by Three Days Grace. The lyrics of this song show a lot of hopelessness. First the singer shows how much he hates his girlfriend and asks why he does love her. This is an indication that relationships are more or less meant for convenience and that a person can hook up with just anybody. The listener may fail to get the reason why love is mixed with hate in this song. The singer claims that he loves his girlfriend and yet he hates everything about her. Life is also portrayed negatively since it does not make sense for the singer to continue seeing his girlfriend if he hates everything about her. As stated above, the lyrics show how hopeless life is to the singer. This is a perfect example of thinking errors caused by depression. Advertising Looking for essay on psychology? Let's see if we can help you! Get your first paper with 15% OFF Learn More It can be assumed that the singer spends a lot of time thinking about how imperfect his girlfriend is and being angry about it. This is the definition of depression. The song can potentially make another person to scrutinize their relationships more leading to a depression like that of the singer. Another similar song is She Hates Me, a rock song done by Puddle Of Mudd. The singer explains how he met a girl and fell in love with her. After knowing each other, he came to realize that she hated him. It is apparent from this explanation that the singer is very negative towards relationships and life. All he can see in the relationship is that the girl hates him and he cannot help to say he is glad that he split up with her. The lyrics are very hopeless and shows a person who lacks self esteem and who is probably in depression due to the same. The negativity in the sing can also be very infectious to a listener who likes the song. It may make the listener to develop the characteristics of the singer portrayed in the lyrics. From the discussion above, it is apparent that the lyrics in popular music can have very disastrous effects on its listeners. People listening to negative, pessimistic and angry lyrics in a genre they like may be influenced to develop these characteristics. Most of these cases may eventually result in the depression of the listener due to the thinking errors in the song.

Essay on Critical Psychology and its critics on the four mainstream

On Critical Psychology and its critics on the four mainstream psychology approaches - Essay Example These mainstream approaches are most commonly taught in universities and colleges and more often used by clinicians and researchers in explaining human behaviour (Prilleltensky & Fox, 1997, p.4). The behaviourist or behaviourism approach is concerned mainly with observable behaviour as opposed to unseen emotions like feelings or thoughts. This approach believes that behaviour manifests as a response to a stimulus. It also believes that our behaviour is largely determined by our environment (Simply Psychology, n.d.). The humanistic approach emphasizes on the importance of studying consciousness and human experience in order to completely explain behaviour. It highlights the importance of â€Å"more individualistic and idiographic methods of study, particularly in the areas of personality and abnormality† (Walker, n.d). It also focuses on the value of responsibility and freedom of choice. The cognitive approach in psychology focuses on our thought processes, how we think-and how such thought processes affect our behaviour (Psychologist World, 2008). This approach focuses on using the scientific approach in explaining human behaviour. â€Å"Cognitive†¦ psychologists attempt to create rules and explanations of human behaviour and eventually generalize them to everyones behaviour† (Psychologist World, 2008). The psychodynamic approach was popularized by several psychologists. Sigmund Freud founded this approach which â€Å"emphasized the influence of the unconscious mind on behaviour† (Wagner, 2008a). He believed that the mind was composed of three elements: id, ego, and superego. Erik Erickson’s approach was also classified as psychodynamic. He expanded on Freud’s theories and emphasized the importance of growth throughout the lifespan. These mainstream approaches to psychology have been criticized by various practitioners, especially by emerging critical psychologists. They believe that mainstream

The condition in the prisons of England and Wales is no different; rather it is worse than many developed countries in the world and the most significant issue behind this crisis happens to be massive overcrowding in prisons soaring at a rapid rate. The prisons in England and Wales are severely overcrowded. According to Press Release (2002), the number of people in prisons exceeded 71,500 in 2002, which was about 45,800 in the year 1992. This reveals that the number of people in prison had almost doubled within a span of just 10 years, which in itself was a record. Within Western Europe, the rate of increase in the number of prisoners is the highest, which stood at 134 per 100,000 in the year 2002, and reached 141 per 100,000 in 2004 (National Offender Management Service, 2005). Prisons have no choice but to admit more and more people as court commands people to be incarcerated every day against different criminal charges. According to Page (2003), the number of women prisoners in 1992 was 1300, while it reached 4000 in the year 2002. It shows that the number of women in prisons has risen by about 3 times during a single decade. The number of children under the age of 18 has also increased three times over the last decade. Moreover, the number of old prisoners over the age of 60 in the year 1989 was 345, which after ten years rose to 1000. This is an alarming condition and if it continues in the same direction there is a threat that it will cripple the entire criminal justice system in England and Wales (Press Release, 2002). This menace is further exacerbated with expected rise in the number of prisoners in future. The government opines that the number of prisoners in UK will reach 100,000 by the year 2010 (Page, 2003). If this prediction becomes true, the situation and environment in prisons will further be worsened, as the system is not capable to bear pressure of soaring prison population to such an extent. With the increasing number of prisoners to be fitted in the same number of prisons and cells, the prisoners are being located in narrow cells that are not designed for two or three persons at the same time. The number of beds, toilets and other facilities intended for a single person are to be shared by more than one. According to a report by House of Lords/House of Commons Joint Committee on Human Rights (2004), this surging number of prisoners has caused massive overcrowding in prisons and about 17000 prisoners happen to have been accommodated two in a cell designed for one. National Offender Management Service (2005, p16) states that, "the ten most overcrowded prisons in England in 2004 accounted for 5,900 out of the 18,400 prisoners required to share a cell in crowded conditions".

The Role Of The Catholic Religious Education Specialist Teacher Article

The Role Of The Catholic Religious Education Specialist Teacher - Article Example Religious education encompasses various areas such as evangelisation, catechesis, giving witness, introduction to church, prayer, experience of faith, and knowledge of other faiths. At the same time, the Religious Education specialist teacher’s duties need to be performed on the basis of what the Catholic church teaches; what the government states: the curriculum for excellence; and what schools expect from them in the context of any extracurricular duties which are not expected of other teachers in the school. Thesis Statement: The purpose of this paper is to investigate the role of the Catholic Religious Education (RE) specialist teacher, the various areas of religious education, and the influence on the RE’s role by the Church, the government and the school. Religious teaching can be understood as a ministry with a professional dimension (Cook & Hudson, 2006). Catholic educators need to think and act sentire cum ecclesia which refers to the ideal form of thinking and feeling with the church on the basis of individuals’ identity as Catholics. ... ng to Cook & Hudson (2006: 399), assessment of religious teaching as a profession can be based on a framework composed of the following characteristics: "essential service to society, motivation by a call to serve, special knowledge and skills, specialized and advanced university training, public trust and status, code of ethics and performance standards, and professional organization".Religious Education helps in students' development of the self, socially, morally and spiritually (SCAA, 1994). Research conducted by Sikes & Everington (2001) indicates that a religious education teacher's life history plays a vital part in determining their teaching skills and approach to work. Further, "the quality, range and flexibility of teachers' classroom work are closely tied up with their professional growth - with the way they develop as people and as professionals" (Hargreaves, 1994: xi). This evidence would be useful in screening potential candidates for training as RE specialist teachers, by addressing negative identities unsuitable to carry out the important work. Evangelisation and Catechesis Ecumenism is the essential task of the whole Church to bring the Gospel to the entire world. Ecumenism and mission, evangelisation and Church community converge in a common witness to the same God (Houtepen, 1998). The Church's evangelistic mission is expected to be carried forward by the RE instructor by imparting the Faith to all students in the classroom, including those students who do not share the Christian faith, in the interests of sharing the wisdom and benefits of the Catholic religion (Francis et al, 1996). Teachings of the Catholic Church are mainly through catechesis. Bishop O' Donoghue (2008) believes that the key element or essence of the aims of a

U.S. Totalization Agreement With Mexico Essay Example for Free

U.S. Totalization Agreement With Mexico Essay The focal point of this paper is to analyze the Totalization Agreement between the US and Mexico. It should be noted that the aspects of this analysis is not fundamentally policy analysis but it intended towards presenting arguments from the point of view of analytical framework. In this paper there would not be any bias or opinion presented rather a comparison would be presented in terms of arguments for and against the issue. It should be stated that in the context of globalization the Totalization Agreement is a very important aspect for the US. Totalization Agreement has the tendency of investment funds and businesses to move beyond domestic and national markets to other markets around the globe, thereby increasing the interconnectedness of different markets. Globalization better said is the shift in the direction of a more incorporated and interdependent World economy. Globalization has had the effect of markedly increasing not only international trade, but also cultural exchange. some intellectual define globalization as convergence of prototypes of manufacture and expenditure and a consequential homogenization of customs, while others strain that globalization has the prospective to take countless miscellaneous appearances. In economics, a wide description is that globalization is the union of prices, wages, products, profits and rates of interest in synchronization with developed nation norms. Globalization of the financial system depends on the position of international business, human migration, incorporation of pecuniary markets, and mobility of capital. The International Monetary Fund observes the increasing financial interdependence of countries all over the world through rising quantity and multiplicity of cross-border dealings, gratis international capital flow, and comparatively faster and extensive dissemination of technology. In contemporary economic scenario the prevailing trend is expansion in the global market. Global market expansion is nothing but a concept of serving customers beyond the limits of domestic market and in economic scenario considered a key growth strategy. Global market expansion is a business reality that every company encounters at some point in its evolution. Under such circumstances every business venture must balance risk with rewards, the risks when expanding internationally can be less predictable and in the same way the rewards can be more elusive. The companies, which are looking for sustainable ways to grow and diversify their revenue streams, consider global expansion as a strategic option. There are several factors behind the trend toward expansion in the global market. Companies require a global presence. For both offensive and defensive causes, companies cannot overlook opportunities outside their home markets. A company’s requirement for a global presence arises from two factors, their capability of leveraging domestic relationships outside their country and a requirement from domestic customers to support the company’s products internationally. A global expansion allows companies to replicate successful domestic strategies in international markets, potentially in markets with lower competitive intensity. Additionally Global market expansion provide the companies large untapped markets, advantages of low labor costs, savings of shipping costs, speed and efficiency of delivery system, etc. These factors make the Totalization Agreement between the US and Mexico more important. (Fletcher, 2006) The Totalization Agreement between the US and Mexico could be better understood in the light of the history behind it. For more than thirty years US has been establishing agreements relating to social agreement internationally keeping in mind that these agreements should coordinate with the program by the Social Security of the US. These agreements based on the aspects of programs related to Social Security of the US are cumulatively pronounced as totalization agreements. Under these agreements there are certain advantages. However, from the point of view of the US these advantages can broadly be divided into two parts. The first objective is to eradicate double taxation for workers employed in foreign nations. Without the agreement an individual would have to pay two times as tax on the earnings. The current report suggests that the benefit of Totalization Agreement between the US and other countries has help US workers working abroad at lot. The cumulative savings are estimated at $800 million per year. The second objective of Totalization Agreement between the US and other countries is to provide an individual who is part timer as a worker in either in the US or the foreign country the proportional tax benefit that is so important for the worker. In this context the agreement between US and Mexico becomes very important in the context of financial benefits. It has been estimated that once the agreement of Totalization is signed between the US and Mexico the workers from the United States in Mexico would be able to save about an estimated $140 million. These savings would be made in the parameters of Mexican taxes relating to health insurance and social security measures. However, it should be mentioned that this estimation is calculated on the basis of a 5 year term of computation. Again, in the perspective of humane benefit it would immensely help the workers who have been working in Mexico for a shorter period of time in both US and Mexico as because this agreement would help them to receive the benefits. (King, 2006) It could well be stated that Mexico is a prominent partner of the US in terms of trading. In fact it is the second largest after Canada. This way it becomes important for the US to indulge in Totalization Agreement with Mexico. As it is Mexico is already under the Totalization Agreement with Canada making it mutually beneficial for both countries. The advantages and disadvantages of Totalization Agreement with Mexico have been heavily scrutinized and debated in recent years. Proponents of Totalization Agreement with Mexico say that it helps developing economies catch up to highly developed industrialized economies much faster through increased employment and technological advances. Critics of Totalization Agreement argue that it weakens national sovereignty and allows rich nations to ship domestic jobs overseas where labor is much cheaper. The main advantages of Totalization Agreement are as such, increased free trade between the two nations, increased liquidity of capital allowing investors in developed nations to invest in developing nations, conglomerates are having greater flexibility to operate across borders, global mass media binding the world together, increased flow of communications allowing vital information to be shared between individuals and conglomerates through out the globe, greater facility and speed of transportation for goods and people, reduction of cultural barriers increases the global village effect, spread of democratic ideals to developed nations, greater interdependence of nation-states, reduction of likelihood of war between developed nations , increases in environmental protection in developed nations. Along with the advantages there are also several disadvantages of Totalization Agreement, such as increased flow of skilled and non-skilled jobs from developed to developing nations as companies look for the cheapest labor, increased probability of economic disturbances in one nation effecting all nations, business influence of nation-states far exceeds that of civil society organizations and average individuals, apprehension that control of world media by a handful of conglomerates will limit cultural expression, greater possibility of reactions for globalization being violent in an attempt to conserve cultural heritage, greater danger of diseases being transported inadvertently between nations, spread of a materialistic lifestyle and outlooks that sees consumption as the path to affluence, international bodies like the World Trade Organization interfere with national and individual sovereignty, increase in the probabilities of civil war within developing countries and open war betw een developing countries as they compete for resources, decrease in environmental integrity as polluting corporations take advantage of weak regulatory rules in developing countries like Mexico. It could well be stated that in this competition organizations are gradually loosing their ethnic values and morals. Today competence of an individual or a corporate is judged by his or her ability to cope up with constant fundamental changes in the organizational structure. All over the world, organizations aligning new products engineering teams around ‘pit crew’ model. Cross functional teams to design, manufacturing sales and service engineer’s work along with the workers, who at some point of time have stake in the product. This ensures manufacturing and sales people having their say all through the design process and building up the manufacturing capability early on that is currant engineering. The goals are simple, such as speed, equality and competitive price. Commodities have become international for most industries and the impact of engineering is significant. In many organizations, the learning curve in engineering has become an unaffordable luxury. Competitive pressures mandate finding ways to reduce the total time required to introduce new products in the market. Competition along with more complex production and distribution environments requires identifying and reducing necessary costs, such as costs associated with development, manufacturing, distribution and service. However, it can be stated that totalization agreement would have a distinct effect on the Trust Funds but it would be a long termed and virtually negligible effect. It has been estimated that the social security of US bears a cost of about $100 million yearly. This has been the trend for the last 5 years. Thus the totalization agreement would enable the workers of both the US and Mexico to enjoy the advantage of cost benefit as the dual taxation would be eradicated. It should be mentioned in this perspective that the cost benefit of US during the year 2002 was around $198 million with Canada alone under the parameters of the totalization agreement. (Lamb, 2004) Thus in the conclusion it could be stated that there are both advantages and disadvantages in coming into a condition of totalization agreement with Mexico. However, when an international agreement is signed there are multiple aspects to be looked after and these are done keeping in mind the mutual benefits of the nations.

The Use Of Mechanical Ventilators Engineering Essay

The Use Of Mechanical Ventilators Engineering Essay The respiratory system, composed of different structures, is involved in ventilation and gas exchange. Its main function is to provide a surface for gaseous exchange of oxygen and carbon dioxide [1]. Gas exchange is performed at the alveoli, specialised cells which are part of the lung parenchyma. It provides oxygen to the blood and removes the carbon dioxide produced in the body as a product of cellular metabolism; for the oxygen to reach the lungs there must be a series of tubular structures that communicate with the outside. The diagram below shows a block diagram of the anatomic structure for the respiratory system (Fig. 1). Figure Block diagram of the Respiratory System anatomic structure Air diffusion into these channels is conducted by the respiratory muscles (intercostals and diaphragm) which increase and decrease rhythmically the size of the thoracic cavity (inspiration and expiration). The pleural cavity contributes on this phenomenon when its negative pressure opposes the elastic recoil of the lung; this action gives place to a conductive portion of the system, whose function is to allow air penetration. In addition the respiratory portion composed bronchioles, alveolar ducts, alveolar sacs and alveoli; establishes homeostasis. Figure Muscles and Pressures involved during breathing The ventilation of the lungs can be measured by studying a gas volume and its variations in the lungs [2]. Boyles, Charles, Daltons and Henrys law of gasses are critical in the understanding of gas exchange, measurement of gas movement take an important part in mechanical ventilation. During breathing movements are cyclic, and volume in the thoracic cavity is changed by the muscles mention before. During inspiration the pressure within the thoracic cavity and lungs is decreased and the same time the volume is increased, allowing air flow in. On the other hand during expiration the elastic lungs and the thoracic wall recoils producing an increase of pressure but a decrease in volume; allow letting air flow out (Fig. 1). Figure Respiratory performance and volume relationships Figure 3 At the same time, inhalation and exhalation allow the mobilization of the volume of gas which can vary depending on the type of respiratory movement and lung elastic forces. Lung capacities are defined by the sum of different volumes. Figure 2 shows a graphic representation of the respiratory performance volume relationships. FCR (Functional Residual Capacity) represents the remaining air after a cycle. VT (Tidal Volume) is the flux of air in a normal inspiration and expiration. IRV (Inspiratory Reserve Volume) is the amount of air moved during a maximum and forced inspiration and results over the Tidal Volume. Similar to IVR, ERV (Expiratory Reserve Volume) is the amount of air mobilised during a maximum and force expiration resulting below the Tidal Volume. The vital capacity is the sum of IRV, VT, and ERV. VR (Residual Volume) as its name says, is the amount of air remained in lungs after a maximum exhalation. The IC (Inspiratory Capacity) is the flux of air after a quiet cycle. A nd finally the TLC (Total Lung Capacity) corresponds to the total volume of gas remaining in the lung after a maximal and forced inspiration. Volumes and lung capacities may be altered in different diseases; its measurement is a critical element for diagnosis, performed by pulmonary function tests. The respiratory parameters: compliance, lung elasticity, intrathoracic pressure, airway resistance, intra-alveolar pressure; help measure the strength in muscles when breathing. Airway resistance is determined by the Poiseuille Law (eq. 1): {1} Where ÃŽÂ · represents the viscosity of the fluid, l is the longitude in the airways, and r is the radio on the airways. Resistance has a great significance in pulmonary physiology; and it is analysed by the ratio of the pressure differential flow. The airway resistance can be increased significantly in the presence of disease such as Bronchitis, Asthma, and Emphysema among others. In addition a great amount of patients admitted to intensive care have need of some form of respiratory support; due primarily to hypoxaemia or ventilatory failure. Respiratory support ranges from oxygen therapy by face mask, through non-invasive techniques such as continuous positive airways pressure, to full ventilatory support with endotracheal intubation[3]. Figure Block Diagram of a basic mechanical ventilator A mechanical ventilator is an automatic machine, designed to provide all or part of the work the body must produce to move air (gas) from the inside to the outside and vice versa. Furthermore mechanical ventilators are designed to transmit energy applied in a predetermined manner to perform a specific task. Interface between machine and patient stable, energy source, control system (for timing and size of the breaths regulations) and monitoring (device performance and patients condition) are the general requirements for ventilators (Fig. 4). A further analysis as well as comparison of this equipment will be made along the paper, with the purpose of a better understanding of its designed and future developments. Current State of the Art Since the invention of artificial respiratory supply, mechanical ventilators have evolved in the past 40 years. There are five generations of mechanical ventilators where changes have been made in order to present a better apparatus. The first generation consisted of only one mode of ventilation, and the electronics used was primitive compared to the one used nowadays. The equipment was no safe since the control with the user was not precise and it did not count with any alarm system. The second generation provided basic alarms, containing electronic circuitry as well as an analogue control of fluid. A major evolution took place on the third generation; digital electronics, microprocessors, were employed for most of the functions. The fourth generation included modern displays such as CRT or LCD ensuring a better patient care. The generation currently used is the fifth generation which features a better onscreen display control. It is also made by advanced logarithms that permit graphic display, calculation of lungs mechanical properties, and system diagnostics. Principles of Operation Mechanical ventilation is all different types of procedures that provide artificial respiration employing machinery to meet the respiratory function of a person who cannot perform it by itself [4]. In addition Mechanical Ventilation (MV) is the product of interaction between a ventilator and a patient, and through this equipment parameters of volume, flow, pressure and time are controlled. Considered as a generator of positive pressure that supplies active phase of the respiratory cycle; there are basically four types of MV: controlled by pressure, time, volume and flow. Mechanical ventilation systems create an intermittent positive pressure where air or a gas mixture enriched in oxygen is insufflated in the patients airway. Pressure in the airway at the end of passive expiration and that at the same time goes beyond atmospheric pressure is known as positive end-expiratory pressure (PEEP) [5]. PEEP is extremely important in effects and mechanisms of the respiratory system. It plays major roles in gas exchange, lung mechanics, and hemodynamic effects. Some effects in lung mechanics it prevents the lung from collapsing, increases FRC among others.[5] In order to provide respiratory support, a MV such as the one in figure is used. Figure Flow and control of gas exchange during artificial ventilation Input of this system provides O2 as a medicinal gas; and in the case of portable ventilators the medicinal gas can be supplied by a dry air compressor. Ventilatory gas is passed through a pressure regulator; which is in charge of preserving the preset pressure for the inspiratory gas and ensures the integrity of the airway. The gas flown to the patient is allocated by an electro-valve (Fig. 5); this remains energised until the end of the inspiratory time previously programmed, when de-energised the gas flow is ceased. Finally the expiratory electro-valve is activated causing the air exhaled by the patient to be expelled to the environment by a biological filter that prevents the contamination of this. Models of Ventilator-Patient Interaction Figure Model representing breathing, were a rigid flow conducting tube is connected to an elastic compartment The Respiratory System can be modelled to illustrate the relations amongst the variables of interest; providing a better understanding of patient-equipment interaction. The model most frequently used is shown in figure where a rigid flow conducting tube is connected to an elastic compartment [6]. When airway pressure goes higher than the base line, the inspiration is assisted (Fig. 6)The Transrespiratory pressure (eq.2) leads inspiration, and is the pressure at the airway opening, ,minus the pressure at the body surface: {2} At the same time has two components, transairway pressure (eq. 3) and transthoracic pressure (eq. 4): {3} {4} A mathematical model that represents volume, pressure and flow during ventilation is known as the equation of motion for the respiratory system [6] (eq. 5) : {5} Where is the pressure generated by the ventilator, is the pressure generated by the ventilator muscles, is the respiratory system elastance, is the respiratory system resistance, and is lung volume where the derivate of volume with respect of time is the flow in the system. Table (1) compares typical values against values during mechanical ventilation [6]. Table Pressures and Volumes during Mechanical ventilation Typical Values Mechanical Ventilation The model provides the basis for monitoring the patients current condition, and it is done in terms of R and E which are mechanical properties. Figure Electrical model representing breathing composed of a RC circuit Another model used for representation is the electrical model (Fig. 7); this model is analogous to an electrical circuit consisting of a resistor and a capacitor (RC circuit), a power supply, which in this case represents the pressure generated by a mechanical ventilator. The electric current stands for the flow of air in the system. In this model, pressure, volume and flow are variables (functions of time) while the resistance and compliance are constant [4]. Second Law of Kirchooff can be used to analyse the electrical model and the following equation(eq. 6) can be derived: {6} Current and charge can be related by , the electrical parameters of the circuit can be now represented by the ventilator variables. When applying a pressure to the input of the system (output pressure of the ventilator), the volume varies according to the following differential equation (eq. 7) the total pressure applied is equal to the sum of the differences in pressure due to the compliance of the system and to the resistance of the airway: {7} According to this system is the output pressure of the ventilator, the inspiratory volume, and is the compliance of the lung [4]. Operating Modes Mechanical ventilators count with different operating modes, which are the manner the ventilator ensures that the patient is provided by the appropriate minute ventilation; satisfying the respiratory needs without damaging any pulmonary tissue. Operating modes can be identified by: breathing pattern, Control type, Control Strategy [6]. When specifying just the breath control variable (Primary Breath Control), there are three approaches: pressure control, volume control and dual control modes. Pressure control (PC) is used when patients can initiate respiration; pressure in the airway is increased during inspiration. Volume control (VC) employs a control system to guarantee that a set tidal volume is distributed during the inspiratory cycle. The Dual Control (DC) is simply a combination of both, used in order to provide minute ventilation while maximizing patient synchrony[6]. Breath sequence is the other component of breathing pattern operating mode. There are two ways airflow can be delivered using this mode, mandatory or spontaneous. The difference between the two of these is that on mandatory breath the ventilator initiates and establishes the tidal volume, Vt. Contrary to mandatory breath on spontaneous breath the patient establishes and starts its own breathing. From these, three different modes of breath sequence can be delivered: Continuous Mandatory Ventilation (CMV), Continuous Spontaneous Ventilation (CSV), and Intermittent Mandatory Ventilation (IMV). CVM and CSV, all breaths are mandatory or spontaneous respectively; however in IMV breaths can be either mandatory or spontaneous [6]. Controls In order to select breathing mode and ventilation pattern parameters, controls are used. There are two different ways on which breathing can be controlled, and at the same time there are control strategies which depend on the variables and parameters set to obtain this. A system can be controlled by an open loop or closed loop (Fig. 8). Like any open loop system, there is no feedback, and the system could be affected by mechanical changes in the lungs, patients ventilatory efforts and leaks [6]. Figure Control systems used for mechanical ventilation Closed loop sense breathing variables such as pressure, volume, and flow to provide a feedback signal which is compared to the desired value set at the input. There are different types of closed loop systems depending on the number of variables used. The instruments used to measure volume-flow rate are referred to as volume flowmeters; they may be classified as rotameters, penumotachographs, hot-wire anemometers, time-of-flight flowmeters, ultrasonic flowmeters, and vortex flowmeters [2]. Depending on their principle of operation, flowmeters can be classified in four main categories: rotating-vane, ultrasonic, thermal-convection, and differential pressure flowmeters. Rotating-vane Flowmeters These types of sensors contain a small motor or turbine which rotates with airflow, and then flow rate is related to the revolution of the rotor. This type of flowmeter is commonly used in ventilator machines and respiratory monitoring [2]. The spins are detected optically and converted into voltage to be recorded or displayed. Ultrasonic Flowmeters Ultrasonic flowmeters can measure instantaneous flow and the effect of the flowing gas on the transit time of the ultrasonic signal [7]. A crystal is used for transmitting and receiving and it is placed externally and obliquely to the axis of the tube through which the gas flows [7]. The time elapsed will depend not only on the velocity, but on the temperature as well as composition of the gas analysed. One main advantage of this type of transducer is that unidirectional flow can be measured, which is applicable for clinical monitoring. Thermal-Convection Flowmeters Thermal sensing technologies are usually made of hot wires, metal film, and thermistol which all use heat to sense gas flow. The wires are heated by an electric current and the heat transfer is used to measure the gas flow [2]. The wire is heated above flow gas temperature, to associate temperature differences; a metal mesh is placed at both ends of the tube. This type of sensing is limited to only one flow direction, more sensors can be located in the tube for multiple directions and for breathing a calibration factor must be considered. [7]. Differential Pressure Flowmeters Flowmeters that use the relationship of pressure drop with airflow through a system. There include elements such flow resistors. Common Failures Figure Closed system during mechanical ventilation The most common failures presented in MV are mainly as a consequence of poor maintenance and user error. Leaks in the circuit due to bad connections or due by perforations in tube are a frequent dysfunction. Leaks stop the proper delivery of tidal volume as well as an accurate sensing flow from the ventilator. PEEP can also be affected by this interfering with O2 saturation (Fig. 9). At times, when an patient with intubation is not able to trigger the ventilator, or the ventilator senses by mistake a patients effort and delivers breaths, is known as patient-ventilator dyssynchrony. As a result the machine delivers an unsuitable breath to the rate of the patients inspiratory efforts. This type of error is also identified as trigger failure or desynchronisation, mismatching, and fighting the ventilator [8]. One cause for patient-ventilator dyssynchrony is fixing the trigger sensitivity improperly. When a desynchronisation with the patients efforts to initiate a breath exists, work of breathing can occur which can be accompanied with respiratory distress preventing pulmonary gas exchange.. Another usual failure is due to user error with the interface. MVs are complex equipments, and the need of the clinician to be familiar with the machine is crucial. It is important that Mechanical Ventilators count with an audible and visual alarm when detecting a leakage or disconnection. Possible hazards to humans Problems may occur while using a mechanical ventilator, especially with patients that been required the use of a MV for a prolonged amount of time. The risks occasioned by the use of respiratory support can lead to severe harmful or even death. Common hazards that may occur due to the use of a ventilator are: infections, pneumothorax, and lung injury. Infections The most common risk reported is acquiring Ventilator-associated pneumonia, which is caused by an infection. The tube allows germ (bacteria) to penetrate more easily into the lungs. This can cause pneumonia. Pneumonia can be a serious problem and may mean that a person may not be able to initiate respiration leading to a longer use of a MV. In addition a recent study reported factors related such as the development of shock, and renal failure [9]. In order to prevent infections a number of control procedures can be performed, and these include maintaining the ventilator as well as the breathing circuit [8]. Pneumothorax Occasionally when a part of the lung is weak, this may become over full of air and as a result an air leak may occur. The leak allows air into the space between the lung and chest wall. The air in this region occupies space in a manner that the lung begins to collapse. If there is air leakage, a chest tube into is used to drain the excess air; allowing the lung to re-expand and stop the leak. Lung Injury The pressure generated by introducing air into the lungs with a ventilator can damage the lungs. Furthermore, very high levels of oxygen can also be harmful to the lung. As a solution to try to keep this risk to a minimum the lowest pressure necessary as well as the only oxygen needed is supplied. Prolonged intubation usually defined as a period longer than 48 hours [10] may lead to swallowing dysfunction. This is mainly caused by impairing glottic closure reflex, reducing subglottic pressure, limiting laryngeal elevation, desensitizing the larynx and hypopharynx, and causing disuse muscle atrophy of the larynx and pharynx [10]. Advantages and limitations of various techniques Once analysed the principles of operations and risks of Mechanical Ventilators, for a better understanding of these is necessary to mention the advantages and disadvantages that they could bring. The impact MV have had over the past 40 years is massive due to the fact that mechanical ventilators provide vital support. Nowadays ventilators found in the market present vast options in terms of modes, control and displays which in many cases can result complicated and the knowledge of these is required[8]. In addition features need to be evaluated in order to establish which configuration mode is suitable for each patient [8]. Ideally hospitals should acquire equipment that incorporates the latest development in ventilation; however as mention before this could lead to complications and misuse of the devices. Requesting companies training to all staff involved in the use, handling and care of the equipment helps to reduce the risk [11].The complicity of the equipment could be considered as a disadvantage of MV, nevertheless ventilators with good human factors design provide major advantage [8]. Mechanical ventilators, being devices that provide respiratory support the duration and need may vary from patient to patient; age is also an important factor as well as the condition. Ventilators are usually used in patients that are in Intensive Care Unit (ICU) and after remaining in intubation after 48 hours the risk to the patient increases. Weaning from mechanical ventilation (MV) permits patients to restart spontaneous breathing steadily; however some risks are involved [12] and are mentioned in section. Risks and hazards to patients should always be considered when dealing with medical devices; however the benefits that they bring play a major role. But still as an advantage mechanical ventilators as mentioned before, bring vital support where initiation of breathing or respiration cannot be performed by the patient. Critical Comparison Figure Piston pump in HFOV Differences between each mechanical ventilator is defined by their operation mode which establish the flow pattern, pressure and volume delivered to the patient with the purpose of controlling alveolar ventilation and as a result achieve the goals of mechanical ventilation. Ventilation modes are determined by the combination of breathing pattern, type of ventilation and control. As for this MV operation mode is going to vary according to the age, and state of the patient, in a way that ventilation is provided and the risk is minimal. Requirements As mentioned before, the continuous use of ventilators may induce injury to the lungs. Air strained outside the normal air spaces creates a swelling pressure that may injure alveoli. The name of this condition is Barotrauma, and malfunction to the mechanical ventilation may occur. High pressures or volumes during inspiration, or when extreme PEEP is used are causes of Barotrauma. There has not been found an association of clinical injury with the level of pressure used, the problem is estimated to be an over expedition of volume [13]. High frequency ventilation(HFV) is a ventilation strategy for patients with respiratory failure; providing a small source of tidal volumes (VT) which is in most of the cases less than the anatomic dead space volume, with respiratory rates above 150rpm. Modern Research studies have shown that HFV can help reduce barotraumas in normal and injured lungs [14]. Figure Flow during high frequency ventilation HFV can be classified according to the source that generates their frequency and the type of exhalation phase; there are four types: High Frequency Jet Ventilation (HFJV), High Frequency Oscillatory Ventilation (HFOV), High Frequency Flow Interruption (HFFI), and High Frequency Positive Pressure Ventilation. The most commonly is used is the HFOV where in a continuous positive air pressure circuit the frequencies are oscillated by a piston pump (Fig. 10). During inspiration, each high frequency pulse in the flow creates a profile shaped like a bullet (Fig. 11), with the central molecules moving on beyond the airway than those found in the periphery. Table (2) describes and compares main differences between common ventilation and high frequency ventilation. Table Comparison between HF ventilator and Conventional ventilator HFV Conventional Ventilator Frequency is measured in Hertz (Hz) Frequency is measure in rpm Uses Displacement Volume (Vd) Uses Tidal Volume (Vt) Volume per minute is measured: Volume per minute is measured: Medical Devices Available on the Market There is a wide range of medical ventilators currently available on the market, and they all offer variety of options ranging in modes, variables monitored and ways of control [8] . Specific requirements and recommendations can be separated according to the complexity based on their performance. Some of the most common brands available nowadays are listed in table (3), and they all offer ventilators that may vary according to specific needs.

In addition the ability to link multiple devices on one is now available, where the ventilator monitor can display lectures from other devices. Portable devices are starting to become more common, they are light and compact devices. Important upgrades have been made to portable devices, where advanced features are now presented. Current portable ventilators present various modes of ventilation and longer power supply. In order to avoid complexity, it is important when developing new features to consider the principal use of ventilators, which is respiratory supply. In addition for longer term care many features may not be used and costs can increase. Conclusions Mechanical ventilators are vital equipments that provide vital support to a patient. They provide artificial respiration to patients that cannot breathe on their own. Their principle of operation is based on mechanical exchange of gases, and their circuitry includes electro-valves for their control and flowmeters as transducers. MV can become very complex devices, training of clinicians using them is crucial in order to avoid risks to patients. Hazards to patients may occur when used for more than 48 hours, however new techniques like high frequency ventilation can reduce this. There is a wide range of devices present on the market and they all vary on their modes of operation. Portable devices are now popular and present important features. Mechanical ventilators are used every day in hospitals and represent a critical part on vital support.
