Quantitative Easing - Decreasing Interest Rates Research Paper

Quantitative Easing - Decreasing Interest Rates - Research Paper Example The practice is entirely different from the usual approach of purchasing and selling government bonds to maintain a targeted market interest rate. It must be emphasized that a central bank uses new electronically created money for the purchase of financial assets in order to implement quantitative easing policy. This practice is helpful for increasing excess bank reserves which in turn may lower yields. The ultimate goal of the quantitative easing policy is to cut down long-term interest rates so as to stimulate economic activities. For this purpose, monetary authorities purchase financial assets of longer maturity and thereby reduce long-term interest rates on the yield curve. In addition, the tool of quantitative easing is very helpful to ensure that inflation rate does not fall below the targeted level. This paper will analyze the pros and cons of quantitative easing and will discuss whether the Fed has a choice of using this tool in a highly recessionary economy. Benefits of Quan titative Easing As Elliott (2009) purports, the unconventional quantitative easing monetary policy may assists banks to keep excess reserves with them and hence to lend largely to businesses and individual borrowers. In turn, businesses will use these additional funds to finance productive activities including infrastructure development and R&D. Similarly, individual borrowers will use this new fund for their day to day activities or investment purposes. This will ensure effective circulation of money throughout the economy. Hence, these increased economic activities will certainly assist the economy to come out of stagnation and stimulate economic growth. Since this monetary tool is helpful to keep the inflation at a moderate level, it assists regulators to prevent the economy from falling into deflationary conditions. According to Kollewe (as cited in the guardian, 2009), US, UK, and Japan are very much interested in quantitative easing policies as a way to stabilize economic grow th. The writer points out that the US was the first country which used quantitative easing as a response to its recessionary conditions. According to International Monetary Fund, the major developed countries that deployed the quantitative easing policy since the beginning of the 21st century were less affected by the 2008 global financial crisis as compared to other industrially developed economies. During the 2008 global financial crisis, it has been identified that the quantitative easing boosted the financial markets by adding liquidity. A weaker currency that amplified export demand is also identified to be one of the major desirable side effects of quantitative easing policy. To a certain extent, the quantitative easing technique has assisted economies to diminish unemployment rate. While analyzing the US economy, it is obvious that this unconventional monetary tool has played a crucial role in the economy in overcoming the dreadful impacts of the 2008 global financial crisis. As per the report of Hermansson (2010), economists hold the view that US’ entire budget deficit would be funded for a fiscal year, if the quantitative easing has been set as high as $1 trillion. In order to take advantages of the quantitative easing policy, the Fed used the returns of previous bond purchases to acquire new long-term financial assets in 2010.

Upbuilding and Awakening Essay Example for Free

Upbuilding and Awakening Essay In Herbert Marcuse’s (1955) book entitled Eros and Civilization, he provides an elaborate explanation to Sigmund Freud’s idea of unconscious and the principle behind it. Freud’s pleasure principle is the necessary factor that prevails in the realm of the unconscious. The unconscious operates mainly for the realization of pleasure and orients itself to the most profitable scenario in which it can achieve pleasurable reward that is free of pain. However, due to the environment to which any human is not capable of living without, the operation and orientation of the unconscious are impossible to realize. In this regard, Freud formulates another principle that â€Å"safeguards† and dictates moderation to the pleasure principle. Marcuse suggests that there can be found some evidences that there were varying forms of repression happened in the course of history in investigating the taboos that are locked in the unconscious. It can be viewed that Marcuse is pointing that humans are not totally free in the sense that he can literally get all the things he wishes to have or do that will definitely provide him the utmost form of gratification. In some of his passages, we could get an idea that this particular condition of humans in the civilization reveals that the culture that we have had is built by the antagonistic forces namely: the pleasure and reality principle. The unconscious is always being repressed, and safeguarded by reality. Soren Kierkegaard, on the other hand, has presented numerous accounts in relation to the unconscious. His idea of unconscious is rather incompatible with that of Marcuse and Freud. Accordingly, he states that â€Å"the unconscious that is relevant is the one which we wish not to notice, or have chosen to ignore, or perhaps made myself unable to comprehend (Conway, 2002 p. 73)†. Kierkegaard regards the unconscious as the spiritual being which must be directed towards God and not, in Freud and Marcuse’s sense, to the painless gratification. Another objection that Kierkegaard might raise against Freud’s notion of the unconscious is his argument that people have to balance the antagonistic actions of their physical and spiritual beings and not the two principles (pleasure and reality) that run against each other. The proper understanding of the unconscious makes it possible for a person to fully realize his self. This understanding is one of the necessary things that a person has to have in order to rule his own unconscious thereby making him conscious of his self and probably have a conscious relationship to God. The direction and orientation of the unconscious, contrary to that of Marcuse’s account, are toward God. Kierkegaard, in his writings, criticizes the middle class Christians because of his view that these people are not definitely having an excellent relationship with God. He considers this â€Å"flaw† of these middle class Christians as the ultimate source of problem in terms of their seemingly stagnant life. Consequently, he offers an accusation stating that these people are lacking of vision in life, that they are afraid of going out of their limitations, they are scared of change for the most gain and that they are merely conformists. It seems, at this point, that he has a high expectation of those who claim to be Christians. He so believes that if you are a child of God, and maintain an excellent relationship with Him, you must not be afraid of going beyond what is normally expect of you. Hence, Christians have to be a living example of how great God can do to His people. There must be no ordinary average religious people. People who claim to have religion must be have a genuine faith, and that, it should be manifested in all of their endeavor. Going back to Kierkegaard’s criticisms of the middle class Christians, we can see directly that he is taking it too seriously in his view of faith and its manifestation in the Christians lives. Moderation, apparently, is being relegated to the background. The idea that â€Å"Christians must have a superior living because his faith along with his actions would bring them the fortune† is like a conclusion based upon a hasty generalization and fallacious claims. If God truly blesses his children, and we regard that fortune and intelligence, for example, are considered blessings, it can also be surmised that there might be other blessings that He might give to his other children that are far more important than what Kierkegaard is arguing about. Social conformity should not be taken against anyone. Though his criticisms somehow reflect the scenario during his times, they did not provide a strong justification such that we would be able to accept them completely and have them against middle class Christians. The case that Kierkegaard has presented pertaining to those average religious people in his time can also be observed at this point in time, only that, these [criticisms] come in different situations and necessitate perspectives that may or may not contradict that of Kierkegaard’s.

Relationship Marketing And Traditional Transactional Marketing Marketing Essay

Relationship Marketing And Traditional Transactional Marketing Marketing Essay The approach of a business towards the marketing discipline can generally be categorised as either being traditional or relationship based. Whilst the traditional approach has held sway for the last fifty years there are signs that relationship marketing may assume the dominant position in marketing thinking and application in the near future. This does not mean that traditional marketing will no longer have a role to play. The evidence from a study of the supermarket chain Asda is that its position as the UK number two supermarket brand has been largely achieved by following a traditional marketing approach. Equally, however, market leader Tesco has embraced relationship marketing using its Clubcard to help it build mutually beneficial relationships with its customers. This approach to its marketing has seen Tescos market share and profits continue to grow whilst Asdas have started to decline. On the face of it this would appear to demonstrate that, when it comes to supermarket marketing, the relationship approach is best. However, it is not that simple. The classic four Ps of the marketing mix, Product, Price Place and Promotion, are the cornerstone of traditional marketing with Price and Promotion having been Asdas primary focus. Also, there is an argument that says in the difficult economic times that consumers are currently experiencing then the price and value for money proposition advocated by Asda has more resonance with consumers than ever before. So, which is the most appropriate marketing path for Tesco and Asda to follow or should elements form both disciplines be adopted for optimum effect? This paper analyses the various points of view of both academics and marketing practioners and draws heavily on case study material to draw some conclusions for a possible way forward. Introduction and Background Relationship marketing, which involves the development, growth, and maintenance of long-term, cost-effective, and mutually beneficial relationships between a business and its customers, may be perceived as being a relatively new phenomenon (Grà ¶nroos, 1995). However, this is not the case as its origins actually pre-date the industrial revolution, a time when products were manufactured on a small scale and consumers had direct contact with the manufacturers and merchants from whom they purchased their goods. As industrialisation gathered pace the mass production of goods meant that direct contact between manufacturers and their end customers was no longer practical and middlemen evolved to bridge the gap. This, in turn, resulted in manufacturers becoming distant from their customers and adopting a transactional rather than customer relationship focus to their marketing and selling activities (Sheth and Parvatiyar, 1995). This transactional approach became increasingly sophisticated as marketing developed into a specialist and separate discipline within organisations, alongside the customer services and product quality control functions. The four Ps of marketing mix i.e. Product, Price, Place and Promotion, first muted by Borden (1964), have been a familiar and successful planning and execution framework for traditional marketing practioners since the 1960s. However, this traditional marketing philosophy has been facing an increasingly serious challenge to its dominant position from advocates of relationship-based marketing (Grà ¶nroos, 1995). The introduction of new technologies, such as the internet, has changed the way in which businesses are able to interact with their customers. This, together with the large scale removal of global trading barriers and the increasing homogenisation of consumer attitudes and purchasing behaviour, have all served to fuel what has become known as the globalisation of world markets (Doole, and Lowe, 2008). This new global marketplace for products has necessitated the adoption of new and more effective marketing techniques and concepts by rival businesses striving to compete for the same customers. So rather than rely on traditional marketing techniques, which are based on identifying new prospects, converting them to customers, and completing sales transactions, businesses have increasingly focussed on developing meaningful relationships with their customers in order to both retain their custom and encourage them to spend more. The management of relationship marketing has been greatly facilitated by a change in attitude to the structure of the marketing, customer service and product quality control functions. Rather than these functions being distinct and disintegrated, as is the case in businesses with a traditional marketing focus, relationship marketing integrates these functions to enable the business to get closer to its customers and thus helping it to benefit from increased customer retention, and the nirvana that all businesses strive for, customer loyalty (Fill and Hughes, 2003). Customer loyalty can be defined as a form of repeat purchasing behaviour reflecting a conscious decision to continue buying the same brand. (Solomon et al. 2001, p. 259). Additionally, the financial efficacy of customer retention versus new customer acquisition is well established. Indeed most academic studies on the subject propound the view that the costs of acquiring new customers can be up to five times higher than tho se costs associated with retaining existing customers (Heskett et al., 1994; Webster, 1994; Cespedes, 1995). In the current global marketplace, Jones (1992) believes that businesses have no choice but to build and retain the loyalty of existing customers if they are to survive and grow. Supermarket chains, such as Tesco and Asda, act as a reference point for attitudes to loyalty, with 72% of consumers feeling loyal to at least one organisation operating in the highly competitive supermarket sector, according to a study by the Logic Group, a specialist in loyalty programmes management, and researcher Ipsos MORI (Fernandez, 2009). Tesco Clubcard a key relationship tool Tesco has been the dominant force in supermarket retailing for the last ten years (Seth and Randall, 2001). It remains the market leading supermarket chain in the UK with a 30.4% market share and has, in the early part of 2010, further widened the gap between itself and its arch rival ASDA, a position which has largely been attributed to the success of its recent Clubcard double points promotion (MacDonald, 2010). To succeed, relationship marketing requires the development and maintenance of strong personal relationships with customers. These relationships should include a high degree of mutual interaction and social exchange (Zineldin and Philipson, 2007). Tescos Clubcard is the cornerstone of its customer relationship marketing strategy. Launched in February 1995, Tescos Clubcard gained five million users within its first month of operation and, significantly and somewhat ironically for a loyalty card, 200,000 new customers also joined the scheme (Seth and Randall, 2001). Clubcard works by enabling its users to collect points when shopping at Tesco stores and online at Tesco.com and also at Tescos catalogue store, Tesco Direct. In addition, points can be collected at Tesco petrol stations and by paying for any goods or services using a Tesco credit card. Tesco Clubcard holders can also collect points when making non Tesco purchases, such as paying for gas or electricity through utilities supplier e.on (Tesco website, 2010). These points are then converted into money-off vouch ers for customers to use in store. However, Clubcard is much more than simply a vehicle to reward customer loyalty. By collecting customer data at registration, Clubcard is also a powerful marketing planning tool for Tesco. It enables the retailer to track customer shopping habits, including the products bought and their purchase frequency, thus enabling Tesco to target specific product and service promotions to specific customers, either at the point of sale or at the customers home via direct marketing. Tesco has attracted some criticism for using its loyalty scheme in this way but it argues that it works in the interests of its customers by aiding the business and product development process. Indeed, Tesco Chief Executive, Sir Terry Leahy, states that: We could not have created the dot-com business without the data from the loyalty card (Humby et al, 2007, page 4). As well developing relationships by creating highly targeted and personalised communications for its customers, Tesco has fulfilled another one of the key objectives of relationship marketing with its Clubcard, namely getting its existing customers to purchase more products. For example, using its Clubcard customer data, Tesco can identify possible target customers for its non-food products. It then mails these customers about such products via the medium of its quarterly Clubcard newsletter. This strategy has resulted in half of all Tescos traditional grocery customers also purchasing non food items from the chain (Humby et al, 2007). Data collected from Clubcard users has also been credited with helping to fuel Tescos recent dramatic international expansion with one third of its entire staff now working outside the UK (Humby et al, 2007). Tesco has extended its Clubcard brand into specific customer market segments in order to enhance its relationships with certain groups with a view to increasing sales to those specific customer segments. Clubcard data revealed that families with babies and toddlers who shopped regularly at Tesco did not believe that they could trust the Tesco brand as the best place to buy baby and toddler related products. These customers tended to place their trust in Boots for such products (Humby et al, 2007). A key identified element of successful relationship marketing is trust: The resources of the seller personnel, technology and systems have to be used in such a manner that the customers trust in the resources involved and, thus, in the firm itself is maintained and strengthened (Grà ¶nroos, 1990, p.5) Tesco decided that it needed to specifically address the issue of trust for these customers and created the Tesco baby and toddler club. Membership of the club enables families with babies and toddlers to get double Clubcard points on certain products as well as giving them free parking spaces close to store entrances, a free magazine and access to specialist parenting advice (Tesco baby and toddler club website, 2010). This relationship marketing initiative directly led to an increase of trust in the Tesco brand for baby and toddler products from this market segment and a consequent transfer of market share from Boots. Now Tescos sales volume of baby and toddler products is more than that of Boots and Mothercare combined (Stone et al, 2010). Effective relationship marketing that truly enhances customer relationships and leads to business improvement also requires that the marketing discipline in an organisation transcends all functions and embeds itself in the ethos of the business (Zineldin and Philipson, 2007). Tesco is totally focussed on its customers and information about customer needs and purchasing trends are disseminated to all parts of the organisation not just marketing. Indeed, Tesco claims that everything its does is rooted in customer knowledge (Tesco Careers Website, 2010). So it can be seen that Tescos Clubcard has certainly played a major role in securing and enhancing its market leading position and, as far as contributing to the bottom line is concerned, then there is evidence that it has also generated incremental sales and profits (Humby et al, 2007). Equally it has not caused an increase in overall marketing spend for Tesco as much of the funding for Clubcard has come from the reallocation of resources from other areas of marketing spend, such as TV advertising (Humby et al, 2007). However, it should also be remembered, of course, that Tesco has not completely disowned the traditional marketing concept as its ongoing aggressive price promotions demonstrate. Asda a traditional price-led approach Some academics suggest that here has been a paradigm shift from traditional to relationship marketing (Grà ¶nroos, 1995) and that traditional marketing does not fulfil the requirements demanded by the modern-day marketing concept (Gummesson, 1995, 2000). Kotler (1997), however, argues that the decision whether to use relationship marketing or transactional marketing depends on the industry type and, more importantly, on the needs and wants of the particular consumer. Some consumers will always adopt a short-term attitude in their relationships with suppliers (Zineldin and Philipson, 2007). In these cases traditional marketing based on the transactional approach will always have an important role to play. Asda is the second largest supermarket chain in the UK with around 17% market share (Macdonald, 2010). Its market ambitions are summed up in it mission statement which is to be Britains best value retailer exceeding customer needs always and in its stated purpose which is to make goods and services more affordable for everyone (Times 100, Asda Case Study, 2010, p.34). Asda has recognised the fickle nature of some consumers relationships with their supermarkets and acknowledges that the purchasing motivation of those consumers will always be based on obtaining best value (Zineldin and Philipson, 2007). Asda has, therefore, consistently adopted a transactional approach to its marketing by focussing heavily on two of the four Ps of the marketing mix advocated by traditionalists namely, Price and Promotion. Asda has built its market position around price and value for money, supporting these propositions through heavyweight TV advertising with its TV commercials having now propounded the virtues of Asda price for well over thirty years. Asdas strategic communications director, Nick Agarwal, defends Asdas traditional marketing approach, which focuses on attracting new customers and increasing transactions through its price and value led proposition, by stating that the current economic times dictate this type of offer in the supermarket sector. He says : Our internal data suggests that people are still very nervous about what will happen on the economic front this year. We need to make sure we serve new customers as well as those who are still feeling financially challenged, especially with the increase in VAT and public sector cuts that are to come. We are very conscious that value is still going to be at the heart of what people want in the coming 18 months.'(Costa, 2010). However, whilst Asda has enjoyed considerable success with its traditional marketing strategy, there are now indications that its approach has failed to reverse a slow decline in sales. According to research from Kantar Worldpanel, Asdas sales have fallen by 0.4% in the second quarter of 2010 and its market share has dropped by 1.7% to 16.9% in the same period (Baker, 2010). Asda seems determined to continue to pursue its traditional approach but independent observers are urging the chain to change to reflect new consumer attitudes. Ed Garner, retail analyst at Kantar Worldpanel says. The market has changed considerably and now consumers feel there is more to life than low prices (Baker, 2010). There are even dissenting voices within Asdas own ranks with Asdas new marketing director Jon Owen believing that the supermarket chain must cease its blinkered focus on traditional price-led marketing in order to compete more effectively (Baker, 2010). Asda has, however, made some concessions to relationship marketing through its corporate social responsibility initiatives. These include community involvement projects through its Asda Foundation (Your Asda website, 2010) and the provision of credit to those customers who have been refused credit by other lenders (Hemingway, 2002). However, it would seem that there are still strong forces inside and outside the business questioning whether or not a predominantly traditional marketing approach remains a viable strategy for future success. Summary and Conclusions From the evidence of two contrasting case studies it is apparent that both traditional and relationship marketing have proven to be appropriate for business success within the supermarket retail sector. However, there are indications that consumers are now beginning to expect more than just low prices and value for money from their shopping experience, they have also demonstrated a desire to engage in a meaningful relationship with their supermarket of choice. This relationship, if managed effectively by the supermarket chain, can increase customer loyalty and can encourage customers to their purchasing behaviour for specific product segments, as well as generating incremental sales from new and existing customers. Tesco, has also shown that a customer relationship strategy based on the development of mutually beneficial relationships can, and indeed does, positively impact the bottom line. Asda, for its part appears to be the subject of a struggle between the opposing forces of traditional and relationship marketing. However, this need not be the case. There is no reason why both disciplines should be in opposition. Even if there is a shift towards relationship marketing, many academics believe that traditional marketing, in terms of the four Ps of the marketing mix, remains valid in all types of businesses including supermarket retailing. The argument being that if a business does not have the right price, product promotion or place (distribution) for its products then it will be impossible for it to enter into a mutually beneficial relationship with its customers (Zineldin, and Philipson, 2007). There is, therefore, strong evidence to suggest that a mix of both the traditional and relationship approach is the most appropriate for the Supermarket sector in the UK. Tesco has achieved this balance but Asda has yet to fully embrace the value of relationship marketing acting alongside a more traditional approach. The view that it needs to do this and quickly in order to grow its business appears to be gathering momentum.

A Tale Of Two Cities: Dr. Alexandre Manette :: essays research papers fc

A Tale Of Two Cities: Dr. Alexandre Manette   Ã‚  Ã‚  Ã‚  Ã‚  Dr. Alexandre Manette the great survivor of the Bastille and father to Lucie Manette. Dr.Manette is the most important character in the book. Throughout the book he is the stories backbone. Few subplots ignore Manette.   Ã‚  Ã‚  Ã‚  Ã‚  Dr. Manette loves his daughter. She is the world to him, without her he would still be a crazed old man. Dr. Manette's love for his daughter is clear throughout the story he expresses his thought verbally. When his daughter Lucie is married he tells her â€Å"Consider how natural and how plain it is, my dear, that it should be so. You, devoted and young, cannot fully appreciate the anxiety I have felt that your life should not be wasted.†1 Dr.Manette is a very caring man. Caring, that is the one adjective I would use to describe Dr.Manette.   Ã‚  Ã‚  Ã‚  Ã‚  As I said before Dr.Manette loves his daughter. Lucie Manette is his driving force. Dr.Manette wants little except for his daughter to live a full and happy life and himself to be a part of it. His desire to be a part of Lucie life makes it hard for him to give her up to Charles Darnay. After the wedding Dr.Manette says â€Å"Take her, Charles. She is yours.†2 He does so with a quite sadness. A huge portion of the story revolves about Dr.Manette's past suffering in the Bastille. The Doctors Bastille time is pure hell. Ever after being freed he still mumbles crazy things such as â€Å"It is a lady's shoe. It is a young lady's walking-shoe. It is in the present mode. I have had a pattern in my hand.†3 Outbursts such as that show that he is not nor may he ever heal his scars. Though the book starts after his imprisonment, his Bastille time contains his actions that effects the stories plot the most. The action that truly stands out is his writing and hiding of the letter that later convicts Charles Darnay. The exposure of the letter during the trail is in my opinion the most interesting twist in A Tale Of Two Cities.   Ã‚  Ã‚  Ã‚  Ã‚  Dr.Manette has few contacts with the Defarges however in my opinion the doctors main conflict is with them. In the Defarge's quest for vengeance against the Evermondes they come upon apposing paths with the doctor. The Defarges want Darnay dead. The doctor can not let Darnay die for he has become a large part of his daughters life. The death of Darnay would bare heavily on Lucie's shoulders. We see this when Lucie pleas with Madam Defarge commanding â€Å"You will be good to

Theoretical Model Of Comfort Discomfort Health And Social Care Essay

Seating COMFORT AND DISCOMFORTThe Cambridge Advanced Learner ‘s lexicon ( 2008 ) defines comfort as a pleasant feeling of being relaxed and free from hurting. Hertzberg ( 1972 ) describes comfort as absence of uncomfortableness. The term â€Å" place comfort † is typically used to specify the short-run consequence of a place the human organic structure ( Kolich, 2008 ) . Comfort is a generic and subjective feeling that is hard to mensurate, construe, and related to human physiological homeostasis and psychological well being ( Shen and Parsons, 1997 ) . Seat comfort is a really subjective issue because it is the client who makes the concluding finding and client ratings are based on their sentiments holding experienced the place ( Runkle, 1994 ) . Helander ( 2003 ) stressed ergonomic remains in the place design, where good biotechnologies is a stipulation for comfort. By and large, comfort issues non under argument by research workers are ( De Looze et al. , 2003 ) : ( 1 ) comfort is a concept of a subjectively-defined personal nature ; ( 2 ) comfort is affected by factors of assorted nature ( physical, physiological, psychological ) ; and ( 3 ) comfort is a reaction to the environment. Helander and Zhang ( 1997 ) describes that there is a difference between comfort and uncomfortableness during sitting in office chair. They discuss that comfort is more related to emotional facets like experiencing safe and luxury. Discomfort is more related to physical facets like feeling force per unit area and musculus hurting.2.2.1 The Theoretical Model of Comfort and DiscomfortThe constructs of comfort and uncomfortableness in sitting are under argument. There is no widely accepted definition, although it is beyond difference that comfort and uncomfortableness are feelings or emotions that are subjective in nature ( De Looze et al. , 2003 ) . Seating uncomfortableness has been examined from a figure of different positions. The job with measuring comfort in resp ects to coerce or any other factor is that, comfort is subjective and non easy to quantify. Seating uncomfortableness varies from capable to capable and depends on the undertaking at manus. Comfort, nevertheless, is a obscure construct and subjective in nature. It is by and large defined as deficiency of uncomfortableness ( Shen and Vertiz, 1997 ) . One of the definitions of comfort by Dumur et Al. ( 2004 ) is the pleasant and fulfilling feeling of being physically or mentally free from hurting and agony, or something that provides this feeling. Harmonizing to the ‘European Union Legislation for Drivers and Promote ‘ ( Euroactiv, 2007 ) , the hebdomadal drive clip for truck drivers shall non transcend 56 hours. Commercial trucks are alone in that they are specifically designed to transport heavy tonss over long distances. The drawn-out period of sitting includes higher hazard of back jobs, numbness and discomfort in the natess due to excessively high surface force per unit area under the thighs ( Floyd and Roberts, 1958 ) . The survey by Adler et Al. ( 2006 ) shows that the driver position is non inactive and alterations over clip. Position alterations and uninterrupted gesture are schemes of the driver to avoid mechanical burden and ischaemia of tissue, which has been identified as one chief ground for uncomfortableness. Discomfort feelings, as described by Helander and Zhang ( 1997 ) , is affected by biomechanical factors and weariness. The beginnings of such uncomfortableness are listed in Table 2.1.Table 2.1 Causes of siting uncomfortableness ( Helander and Zhang, 1997 ) .Human experience mannerBiomechanicalSeat/EnvironmentPhysiology causesEngineering causesBeginningPain Pain Pain Discomfort Perspiration Percept Circulation occlusion Ischemia Nerve occlusion–Heat Visual/auditory/tactile Pressure Pressure Pressure Vibration Material Breathability Design/vibration Shock absorber stiffness Seat contour Vehicle drive Vinyl upholstery Vehicle cost Zhang et Al. ( 2006 ) presented a theoretical account that illustrates the interaction of comfort and uncomfortableness as shown in Figure 2.1. Passage from uncomfortableness to comfort and frailty versa are possible in the intersection of the axes. Hence, if uncomfortableness is increased, such as with a longer clip within undertaking and weariness, comfort will diminish. Its agencies that good biomechanics may non increase the degree of comfort, it is likely that hapless biomechanics turns comfort into uncomfortableness. Passage Discomfort: Poor Biomechanics And Tiredness Comfort: Well Being and Plushness Figure 2.1 Hypothetical Model of Discomfort and comfort ( Zhang et al. , 2006 ) . Millet and Pignede ( 2001 ) described the comfort methodological analysis, where is to avoid introducing with a comfort mark and burying other facets. They have explained that when interior decorator make a great betterment on a specific facet of comfort and if, at the same clip, the interior decorator induce a job for another comfort facet, the consequence is the uncomfortable place. They besides defined their â€Å" comfort oval † as shown in Figure 2.2. Figure 2.2 The 10 points of comfort ( Millet and Pignede, 2001 ) . Kolich ( 2008 ) described that seats are required to fulfill culture-based penchants and outlook of place comfort. For illustration, the Western European, by and large, are thought to prefer firmer seats as compared to North Americans. The writer besides visualized the factors that impacting automobile place comfort as in Figure 2.3. Figure 2.3 Factors impacting subjective perceptual experiences of car place comfort ( Kolich, 2008 ) . Position as described by Kolich ( 2008 ) , is the most of import single factor. While the consequence of position is assumed to be important, it is hard to turn to because residents with similar anthropometric features may sit in wholly different organic structure places. Stiffness, geometry, contour, breathability, and titling are considered seat factors. Stiffness refers to the resilience of the place system. Geometry defines place form in footings of breadth, length, and tallness, whereas contour trades with the profile of the sitting surface ( e.g. location and prominence of lumbar vertex ) . The place ‘s geometry and contour must suit the anthropometry variableness of the mark population. Breathability, as it pertains to the soft trim ( i.e. foam denseness and fabric building ) , may impact car place comfort in utmost environmental conditions. Styling must be included as a place factor because aesthetic quality may impact perceptual experiences of comfort, in the same mann er as nameplate or purchase monetary value of vehicle. Runkle ( 1994 ) described the Lear ‘s place comfort benchmarking methodological analysis which incorporates and integrates four tools into a individual comprehensive place comfort analysis ; market research surveies, benchmarking surveies, organic structure force per unit area distribution analyses and human factors surveies of anthropometric informations. The consequences concluded that good aesthetics, well-designed and comfy are more of import than physical parametric quantities in a place design. De Looze et Al. ( 2003 ) proposed a theoretical account of siting comfort and uncomfortableness as shown in Figure 2.4. The left side of the theoretical account is about the seating uncomfortableness. At the human degree, the ‘exposure ‘ , ‘dose ‘ . ‘response ‘ and ‘capacity ‘ is the chief issues of the work-related physical ailments. The external exposure factors bring forthing a perturbation of the internal province ( dose ) of an person. The dosage may arouse a cascade of mechanical, biomechanical or physiological response. The extent to which external exposure leads to an internal dosage and responses, depends on the physical capacity of the person. The loading factor of a sitting individual caused by the physical features of the office place, the environment and the undertaking. These external tonss related to muscle activation, internal force, intra-discal force per unit area, nervus and circulation inclusion, and tegument and org anic structure temperature rise, arousing farther chemical, physiological and biomechanical responses. The right side is concerns comfort, such as feelings of relaxation and wellbeing. In the theoretical account, the physical and psycho-social factors such as occupation satisfaction and societal support are playing a function at context degree. At the place degree, aesthetic design and physical characteristics may impact the feelings of comfort. At human degree the influential factors are assumed to be single outlook and other single feelings or emotions. Figure 2.4 Theoretical theoretical account of comfort and uncomfortableness and its implicit in factors at the human, place and context degree ( De Looze et al. , 2003 ) .2.3 Aircraft Passenger SeatWorld market has become really competitory in the concern and premiere category sections as this tend to give higher net income border in comparing with the economic system whose borders have been undercut by the new low-priced air hoses. The reaching of the new flourishing economic systems of China and India and the bing tiger economic systems pushed the demand for concern travellers on long draw flights really high. The air hoses responded by offering new degree of comfort and edification. The aircraft place maker have designed and manufactured the aircraft rider to guarantee the safety and comfort during air travel ( SEAT, 2006 ) .2.3.1 Current Aircraft Passenger SeatSwiss based company designed the air-filled chamber to replace the conventional froth. Pneumatic shock absorbers adjust a utomatically to siting and kiping places with air Chamberss. Due to the adaptative constructions of air chamber, riders feel no force per unit area points and can set shock absorber soundness separately ( Lantal Textiles, 2010a ) . Since 2009, all concern and first category seats of the SWISS long-haul fleet were equipped with Lantal ‘s advanced pneumatic comfort system. It sets new criterions in rider comfort and has a direct impact on the profitableness of air hoses. Four place companies, viz. , B/E Aerospace, Contour, ZIM Flugsitz and Recaro implemented Lantal ‘s pneumatic comfort system in their aircraft place ( Lantal Textiles, 2010b ) . The Lantal ‘s pneumatic comfort system is a inactive control system, where rider needs to set the hardness of air chamber manually. Thompson Solutions developed new economic system place, the Cozy Suite. The Cozy Suite provides each rider with two armrests. The place is designed to assist aircraft rider to kip. It has contoured shoulder country and offers wider articulatio genus infinite compared to standard siting designs of the same pitch. It besides features a alone hands-free, tip-up place base, which makes it easier to acquire in and out of window seats, and aid to diminish embarkation and deplaning times ( James and Kington, 2008 ) . The new place design claimed to increase 14 % of economic system category rider seats in Boeing B767-400. The Cozy Suite focused on legroom, armrests, air hoses gross, place measure, easiness of emersion, personal infinite and dedicated kiping country ( Thompson Aero Seating, 2009 ) . B/E Aerospace exhibited its economic system category ‘Spectrum ‘ rider place. The new platform is 10 % igniter in weight and provides over 14 % extra life infinite. The developed place includes a graven Crytalflex back support system and meets the 2009 Head Injury Criteria ( HIC ) demands. Recaro Aircraft Seating presented a new version of its single-beam Comfort Line 3610 economic system category place. The place increases the legroom even at a comparatively short place pitch. The new place have comfort characteristics include kinematics that improve the seating angle, a flexible head restraint, a foot cyberspace and ultra-thin visible radiation lightweight aluminum backrest with comfort gauze ( James and Kington, 2008 ) . Air New Zealand introduced the ‘Skycouch ‘ , a lie-flat economic system and premium economic system place in twelvemonth 2010. The ‘Skycouch ‘ is a specially designed row of three seats, has been engineered to make a lie-flat, flexible infinite all the manner to the seat-back in forepart, supplying a topographic point for the childs to play, or the holy grail of economic system travel- a level surface for grownups to loosen up and kip ( Air New Zealand, 2010 ) . Based on the survey on current aircraft rider place development from twelvemonth 2008 to 2010, the aircraft place makers and airliners were focused on the igniter and dilutant place every bit good as more seats to set in the cabin.2.4 EXISTING NECK SUPPORT DURING TRAVEL2.4.1 Travel Type Neck SupportFrom the merchandise hunt utilizing web services, several cervix supports related merchandises were found. There are different types of cervix supports that used during air travel such as inflatable cervix pillow ( Pilot Paul, 2010 ) , polyester filled pillow ( Pilot Paul, 2010 ) , memory froth pillow ( Pilot Paul, 2010 ) , feather filled pillow ( Nick Robinson, 2010 ) and the aircraft place with neck support ( Cathay Pacific, 2010 ; Qantas, 2010 ) .Inflatable Neck PillowThe inflatable cervix pillow can be found from any travel store at low monetary value. The chief job with inflatable cervix pillow is that they normally fail by developing a slow leak and upseting the user during remainder . The air inside the inflatable travel cervix pillow will spread out and contract the as the aircraft alterations altitude. This is because the cabin height alterations in proportion to the plane ‘s height. As the cabin height ascents, the air in the pillow expands. As the plane descends, it contracts. The pillow size alteration is relative to the height alteration. These cheap travel pillows seldom last more than two or three trips. The better 1s do last thirster. Another disadvantage of the less expensive air travel pillows is the vinyl stuff can acquire hot and gluey against your face. The chief advantage of inflatable travel pillows is that they take small room in your baggage. They are besides lighter than any of the other types, particularly the Polygonum fagopyrum 1s ( Pilot Paul, 2010 ) .Memory Foam Travel PillowThe memory froth travel pillow provides tonss of support and stabilisation and is highly comfy. A travel cervix pillow made with memory froth will last many ol d ages. It should last much longer than an inflatable or poly-filled one. Foam travel pillows do an first-class occupation of keeping your caput still therefore leting you to kip. Memory foam casts in response to your organic structure ‘ form, weight and heat to organize a pressure-free cradle of support. When user is non utilizing it, a froth travel cervix pillow compresses good to suit in your carry-on bag. They are comparatively lightweight. While memory froths travel pillows can be some of the most expensive among other neck support pillow ( Pilot Paul, 2010 ) .Polyester Travel PillowThe polyester travel pillow does non supply the support and stabilisation like memory froth or Polygonum fagopyrum travel pillows. Some air hose such as KLM and China Southern Airlines do provide polyester pillow in the cabin. The advantage of polyester travel pillow is low cost ( Pilot Paul, 2010 ) .Feather Filled PillowThe plume filled pillows are really soft, cuddly and fictile. The pillow contours to the caput and cervix sensible good and supply more support than down. The pillow can be scrunched to supply better support to user caput and cervix. The plume pillows weigh really small, normally weigh no more than a lb or two ( Nick Robinson, 2010 ) . Feather pillows frequently do non keep important support throughout the dark because they tend to drop in to some grade. As a consequence, the user needs to set the pillow during remainder. And botching the pillow or agitating it may besides be required to return the pillow to its preferable loft. As the pillow ages, increased fluffing or shaking will be required. The difficult quills of the plumes can frequently be noticed through the instance and can even jab through. Further, the pillow creates crunching-like noise when the pillows are compressed because the plumes can incorporate difficult parts or because the pillow has a fictile bed to forestall the plumes from jabing through. Finally, plume pillows have been known on juncture to hold an olfactory property, possibly of H2O poultry or chemicals used to sanitise the plumes ( Nick Robinson, 2010 ) .2.4.2 Long Distance Commercial Vehicle Passenger Seat with Neck SupportThe Coach Passenger Seat with Neck SupportLong-distance manager services, besides called express coachs or interurban managers, have in common that they cater for conveyance demands outside urban agglomerations, normally from metropolis to metropolis, frequently besides functioning towns non good served by rail on their manner ( van de Velde, 2009 ) . The manager rider place is one of the of import characteristics to guarantee the comfort of the rider for long distance travel. For illustration, an express manager that travels from Singapore to Thailand as showed in Figure 2.5 was equipped with cervix and leg support for their rider comfort during long distance travel. Figure 2.5 The luxury manager rider place with neck support ( Five Star Tours, 2010 ) .The Train Passenger Seat with Neck SupportFor the long distance high velocity rail, such as ICE, Thalys and Eurostar offered luxury rider place to guarantee the siting comfort of rider during train travel. German ICE offered the rider place with the cervix support as showed in Figure 2.6. The cervix support is a soft shock absorber that attached to the place with two strings. Thalys ( Figure 2.7 ) and Eurostar ( Figure 2.8 ) offered similar rider place with same side support for caput and cervix. Figure 2.6 The German train ICE rider place with neck support. Figure 2.7 The Gallic train Thalys rider place with neck support ( Raileurope, 2010 ) . Figure 2.8 The Eurostar rider place with neck support ( Bembridge, 2007 ) .The Aircraft Passenger Seat with Neck SupportThe economic system category place of major air hoses such as KLM, Malaysia Airlines, Qantas Airlines and Cathay Pacific Airlines equipped with adjustable caput remainder to better the caput and cervix comfort during air travel. The headrest of economic system category place is a automatically device that support caput and cervix. The device needs to be adjusted manually by the rider for comfort betterment. The headrest ( Figure 2.9 ) that available in the economic system category aircraft place of Cathay Pacific Airlines able to adjusts in four ways – up, down and sideways ( with the adjustable ears ) . The head restraint is to maximise comfort and support for rider caput and cervix ( Cathay Pacific, 2010 ) . Subsequently, the Qantas A380 economic system category place besides equipped with the caput remainder ‘wing ‘ for caput and cervix support ( Qantas, 2010 ) . Most of the headrest that available in current aircraft rider is a mechanical system where the rider needs to set the caput remainder manually to the needed place. Figure 2.10 showed the Qantas economic system category aircraft rider place. Figure 2.9 The Cathay Pacific Airlines economic system category aircraft place with constitutional cervix support ( Cathay Pacific, 2010 ) . Figure 2.10 The Qantas Airline economic system category aircraft place with neck support ( Travelhouseuk ‘s Travel Blog, 2010 ) .2.5 OBJECTIFYING AND SUBEJCTIFYING OF SEAT ( DIS ) Comfort2.5.1 Relationship of nonsubjective measurings to siting comfort and uncomfortablenessThe design of vehicle ‘s seating for improved drive uncomfortableness is one of the primary ends for vehicle makers. Comfort measuring is hard because of such factors as user subjectiveness, occupant anthropometry, place geometry, and sum of clip spent sitting ( Thakurta et al. , 1995 ) . A great trade of research has been performed in recent old ages to happen nonsubjective steps for foretelling place comfort perceptual experience. Some of the proposed nonsubjective steps include quiver, interface force per unit area, and musculus activity. These nonsubjective steps are correlated with subjective informations to find the comparative effects of each step related to comfort ( Nawayseh and Griffin, 2005 ) . Research has shown that some of the chief factors that affect siting comfort are seat-interface force per unit area distribution, whole-body quiver and force per unit area alteration rate ( Boggs, 2004 ) . Position Analysis CAE Pressure Epinephrine Spinal Loading Oxygen Impregnation Temperature and HumidityObjective MeasurementsElectromyogram Vibration Evaluation Etc. Electroencephalogram A huge bulk of nonsubjective steps used for measuring comfort and uncomfortableness. From the literature hunt, the nonsubjective measuring methods for place such as force per unit area distribution, position, computer-aided design ( CAD ) , computer-aided technology ( CAE ) , temperature, humidness, quiver, electromyography ( EMG ) , and epinephrine. Figure 2.11 shows an overview of different nonsubjective measuring methods for place comfort and uncomfortableness. Figure 2.11 Overview of different nonsubjective measuring methods for place comfort and uncomfortableness. From the literature hunt utilizing computerized systems such as ScienceDirect, force per unit area measuring is used to analyze the uncomfortableness feeling among the drivers. Pressure measuring method is the most used method for the place developer to mensurate the comfort and uncomfortableness of sitting individuals ( Adreoni et al. , 2002 ; Boggs, 2004 ; Lee et al. , 1988 ; Nawayseh and Griffin, 2005 ; Yun et al. , 1992 ) . The instruments that used in force per unit area measuring, viz. , force per unit area mat, force per unit area proctor system, force detector, place distortion mensurating device and force per unit area imagination system. The automotive industry strongly encourages research in the field of nonsubjective comfort appraisal, particularly dedicated to the place and the related positions ( Bustrom et al. , 2006 ; Scarlett et al. , 2007 ) . Driver position is one of the of import issues to be considered in the vehicle design procedure ( Wu and Chen, 2004 ) sing non merely the auto and the user ( Kolich et al. , 2006 ; Schust et al. , 2006 ) but besides the experimental conditions. The instruments that used in the position measuring are camera, optoelectronic system ( Andreoni et al. , 2002 ; Brazier et al. , 2002 ) driving position monitoring system, digital signal processing, supersonic device ( Brazier et al. , 2002 ; Park et al. , 2000 ) , 3D gesture analysis ( Park et al. , 2000 ) , and gesture measuring system ( Bush and Phaeda, 2003 ) . A major part of the quivers experienced by the residents of an car enters the organic structure through the place ( Choi and Han, 2003 ) . Whole-body quivers, which are perpendicular quivers, tend to impact the human organic structure the most. These quivers are transmitted to the natess and dorsum of the resident along the vertebral axis via the base and dorsum of the place ( Wereley and Choi, 2005 ) . The instruments that used are perpendicular quiver simulator, angulator rate detector, accelerometer and whole organic structure quiver measuring. Six surveies have used computer-aided technology ( CAE ) methods to mensurate the sitting individual comfort such as finite component method ( Choi et al. , 2007 ) , practical world ( Marler et al. , 2007 ) , simulation method ( Kolich and White, 2004 ; Seitz et al. , 2005 ; Verver et al. , 2005 ) and unreal intelligence technique ( Kolich et al. , 2004 ) . Other surveies for nonsubjective measurings are related to human physiology. The physiology of human such as encephalon, musculus, bosom, tegument and spinal can be used to mensurate the sitting individual comfort or uncomfortableness degree. The spinal burden measurings have been performed in two surveies. Five surveies are carried out to mensurate the tegument temperature and humidness degree. Two surveies utilizing electromyography ( EMG ) to mensurate the musculus reaction in relation with the capable uncomfortableness feeling. There is a survey which used epinephrine content in the piss to mensurate the driver ‘s stress degree. Besides, the encephalon activity can be detected by electroencephalography ( EEG ) every bit good as O impregnation can be used to mensurate discomfort degree of sitting individual excessively.Pressure Measurements: The force per unit area distribution method is the most common method that used by research workers to mensurate place comfort objectiv ely. Several research workers have measured the force per unit area at the human-seat interface utilizing electronic detectors ( capacitive, resistive, strain gage ) , pneumatic and electro-pneumatic. However, the visco-elastic behaviour at the interface is wholly altered by the detectors used ( Nawayseh and Griffin, 2005 ) . Andreoni et Al. ( 2002 ) used force per unit area mat to garner shock absorber and backrest force per unit area informations during inactive conditions and existent drive activity. Gyi et Al. ( 1997 ) evaluated the place force per unit area measuring engineerings that used in the anticipation if driver uncomfortableness for assorted auto place designs, and supply interior decorators and makers with rapid information early in the design procedure. Lee et Al. ( 1998 ) recruited 100 topics and 16 seats to happen the correlativities between force per unit area informations and comfort. They stated that the correlativity is non high plenty to be the footing for any design determination. Yun et Al. ( 1992 ) studied the correlativity between force per unit area distribution and local uncomfortableness of auto seats. The consequence found that force per unit area distribution at the low back and buttock country was statically correlated to local uncomfortableness in auto seats.There are huge bulk of nonsubjective steps used for measuring comfort. They were created based on the comparing of different place designs with similar types of place shock absorbers that are widely used in the automotive industry, i.e. urethane froth shock absorbers. The kineticss of air-inflated place shock absorbers is really different from that of foam shock absorbers in footings of their interface with the human organic structure. Further surveies should be performed to utilize alternate methods of rating that can efficaciously measure the kineticss at the interface between the shock absorber and the human organic structure. In add-on, the vehicle place interior decora tor should see the soft tissue in contact with a soft place surface. Figure 2.12 shows the assorted force per unit area measuring techniques that used in the place development. Ocular fibres device SAE AM50 cheek signifier indentor Talley force per unit area proctor system Pressure feeling mat ( piezo resistive ) Highest extremum force per unit area measuring Lower extremum force per unit area Pliance system ( Pressure distribution ) Pressure and contact country measuring Pressure detectors Force sensor/transducers Pressure mat Seat distortion mensurating device ( Strain gage )PressureFigure 2.12 Assorted force per unit area measuring techniques.Position Analysis: The automotive industry strongly encourages research in the field of nonsubjective comfort appraisal, particularly dedicated to the place and the related positions ( Bustrom et al. , 2006 ; Scarlett et al. , 2007 ) . Driver position is one of the most of import issues to be considered in the vehicle design procedure ( Wu and Chen, 2004 ) sing non merely the auto and the user ( Kolich et al. , 2006 ; Schusr et al. , 2006 ) but besides the experimental conditions.

Vibration Measurements: A major part of the quivers experienced by the residents of an car enters the organic structure through the place ( Choi and Han, 2003 ) . Whole-body quivers, which are perpendicular quivers, tend to impact the human organic structure the most. These quivers are transmitted to the natess and dorsum of the resident along the vertebral axis via the base and dorsum of the place ( Wereley and Choi, 2005 ) . Since the natural frequence for the human bole falls in the scope of 4-8 Hz, it is expected that the whole organic structure quivers that will most mostly affect riders will happen in this frequence scope ( Ofori-Boetang, 2003 ) . Figure 2.14 shows the nonsubjective measuring methods in quiver analysis. Vertical quiver simulator Angulator rate detector Accelerometer Whole organic structure quiver measuringVibrationFigure 2.14 The nonsubjective measuring methods for quiver analysis. Temperature and Humidity Measurements: Thermal comfort is an of import facet to be considered in the biotechnologies rating of the driver seats, which are important interfaces between adult male and machine in car. Determining thermic comfort in vehicle is a complex undertaking, because thermic comfort involves the interaction of many variables and cars are susceptible to temporal fluctuations in their thermic environments ( Mehta and Tewari, 2000 ) . As shown in Figure 2.15, air velocity, air temperature, humidness and average beaming temperature are used to find the temperature and humidness of the place objectively. Air velocity detector Air temperature detector Mean beaming temperature Humidity detectorTemperature andHumidityFigure 2.15 The nonsubjective measuring methods for temperature and humidness. Computer-aided Technology: Due to the promotion of the computing machine system, computer-aided technology ( CAE ) is used to back up scientists and applied scientists in undertakings such as simulation, analysis, design, industry, planning, diagnosing and fix. The usage of CAE could ease the place development procedure. In the early phases of the design procedure a new design can be tested for its grade of comfort by computing machine simulations with theoretical accounts of the human and the place. This allows makers to rush up the design procedure of a new place or interior and cut down costs. Verver et Al. ( 2004 ) used the finite component theoretical account of the human natess to foretell the inactive force per unit area distribution between human and siting surface by it detailed and realistic geometric description. Hix et Al. ( 2000 ) developed technology methods and expertness in the country of truck place patterning to capture the effects of place kineticss on drive qualit y. Figure 2.16 shows some CAE techniques that used to mensurate the place objectively. PAM comfort simulation tool Virtual Human Mathematica MADYMO RAMSIS AnyBody Modeling System Artificial Intelligence ( GA, Fuzzy, SVM ) ADAMS/ Figure ABAQUA/ CASIMIR ALASKA/ DYNAMICUSCAEFigure 2.16 CAE techniques for place developmentPhysiological Measurements: Biological parametric quantities such as bosom rate, musculus, and piss can be used to mensurate the place comfort objectively. The biological parametric quantity is based on human organic structure physiological or orthopaedic phenomenon. For illustration, electromyography ( EMG ) signals is used to mensurate the myoelectrical activity of musculuss ( Inagaki et al. , 2000 ) , epinephrine in the piss can be used to mensurate the human emphasis degree ( Uenishi et al. , 2002 ) , electroencephalography ( EEG ) is used to mensurate the human encephalon activity ( Zhang et al. , 2006 ) , and O impregnation is used to look into the human uncomfortableness. Lim et Al. ( 2006 ) used a method of ECG measuring without direct contact with the tegument while topics sat on a chair have oning normal apparels. Figure 2.17 shows the assorted nonsubjective measuring methods for physiological analysis.Metabolic ra te Relative humidness ( Skin wettedness detector ) CT scan Electrocardiography ( ECG ) Electromyography ( EMG ) Skin wet trial ( Skincon-200/IBs ) Physiological clime simulator ( CYBOR ) A double manner dynamometer Spinal burden Heat flux detector Skin temperature detector X ray Oxygen impregnation measuring ( Somanetics Oximeter ) Epinephrine Electroencephalography ( EEG )PhysiologyFigure 2.17 Various nonsubjective measuring methods for physiological analysis.2.5.2 Relationship of subjective measurings to siting comfort and uncomfortablenessDue to the deficiency of proved analytical prosodies, vehicle makers have opted to trust on subjective ratings as the chief index of place comfort. The vehicle makers developed elaborative subjective rating protocols that involved extremely construction questionnaires ( Ahmadian et al. , 2002 ) . The questionnaires direct residents to delegate feelings of uncomfortableness to a specific part of place. The questionnaires, which typically contain numeral graduated tables ( e.g. 1 = really uncomfortable to 10 = really comfy ) , produce subjective evaluations that are translated into public presentation requirements/specifications ( Yagiz, 2004 ) . A decently designed questionnaire is paramount because it affords research workers an instrument from which to set up theories ( Brooks and Par sons, 1999 ) .Local Discomfort Rating: Local uncomfortableness evaluation is used to mensurate the uncomfortableness of topics while sitting. Harmonizing to Kolich ( 2008 ) , many research workers have adopted Hertzberg ( 1972 ) definition because, in the current environment, it is more straightforward to quantify uncomfortableness than to mensurate comfort. The local uncomfortableness evaluation graduated table can be rate on a graduated table such as 1 to 10 or -10 to 10. Shen and Parsons ( 1997 ) used the class partitioning graduated table ( CP50 ) for evaluation seated force per unit area strength and perceived uncomfortableness. There are 16 surveies related with local uncomfortableness evaluation. Whereas there are six surveies related to local comfort evaluation.In the survey by Mehta and Tewari ( 2000 ) , 10 point graduated table local uncomfortableness is used to mensurate the tractor place comfort. The work is to project the most appropriate method of appraisal and choice of tractor seats from technology and biomechanical position point. Eklund and Corlett ( 1987 ) used local uncomfortableness with ocular parallel graduated table to analyze the correlativity between bole and back uncomfortableness.Local Comfort Rating: Kyung et Al. ( 2008 ) used several subjective evaluation strategies to look into the most effectual manner for usage in planing and measuring auto place, and to happen the relationship among these strategies. There are entire 27 Participants completed short-run drive Sessionss, in six combinations of seats ( from vehicles ranked high and low on overall comfort ) , vehicle category ( sedan and SUV ) , and driving locale ( lab based and field ) . Overall evaluations were obtained, every bit good as separate steps of comfort and uncomfortableness of the whole organic structure and local organic structure parts.For the aircraft place, Parakkat et Al. ( 2006 ) investigated the long continuance effects of sitting in the expulsion place shock absorber. Subjective comfort study informations and cognitive public presentation informations is used in the probe. Zhang et Al. ( 2007 ) studied the thermic esthesiss, overall thermic acceptableness and thermic comfort on ocular parallel graduated tables. 7-point graduated table thermic comfort for each of the organic structure subdivisions is used in this studied.Body Function: In the organic structure mapping method, the sensed uncomfortableness is referred to a portion of the organic structure. The topic is evaluation the organic structure countries sing uncomfortableness and to rate this uncomfortableness on a given graduated table. Kyung et Al. ( 2008 ) used a ocular organic structure mapping linear graduated table as shown in Figure 2.18 to obtain overall evaluations of comfort and uncomfortableness for the whole organic structure. For the work by Zenk et Al. ( 2007 ) , the uncomfortableness for each organic structure portion is rated on the uncomfortableness graduated tabl e and apportion this appraisal to a specific section of the organic structure parts in touch with the place.Figure 2.18 The organic structure function for comfort and uncomfortableness evaluation ( Kyung et al. , 2008 ) . Seat Function: In the place function method, the place is divided into different subdivision to measure the seating comfort and uncomfortableness. Inagaki et Al. ( 2000 ) divided the place into 16 sections to measure place comfort based on 5-point graduated table. The â€Å" fit † feeling and â€Å" soft † feeling of the sitting place were converted to points of stimulation that the human organic structure received. Figure 2.19 shows the place mapping method by Inagaki et Al. ( 2000 ) .Figure 2.19 Evaluation of place comfort based on place function ( Inagaki et al. , 2000 ) .2.6 TOTAL DESIGNEntire design is defined as the systematic activity necessary, from the designation of the market/user demand, to the merchandising of the successful merchandise to fulfill that demand – an activity that encompasses merchandise, procedure, people and organisation ( Pugh, 1990 ) . Entire design has been developed into an integrating model or methodological analysis that encapsu lates all facets of the new merchandise development ( Ion, 1995 ) . As mentioning to Figure 2.20, entire design is represented by an activity theoretical account that breaks the design procedure into six iterative phases- market reappraisals, merchandise design specification, construct design, item design, fabrication and merchandising. The attack accent the ‘front terminal ‘ of the design procedure and includes many methods which are of direct relevancy to the apprehension of the market demands. The cardinal nucleus of activities as represented by the six stages is present in all design irrespective of subject. All design starts, or should get down with a demand that may be satisfied by bring forthing a merchandise that will suit into an bing market or make a market of its ain. This demand is expanded in the initial phases of the design procedure into a full merchandise design specification. This specification reflects the client demand and influences and restraints the remainder of activity. It is followed by conceptual procedure and it em design. A merchandise that meets the merchandise design specification be developed and specified ( Ion, 1995 ) . Figure 2.20 Entire design activity theoretical account ( Ion, 1995 ) . To enable the design squad to run efficaciously and expeditiously, it is necessary to utilize a broad assortment of techniques and methods. These methods are straight related to the nucleus stages and efficaciously organize the design squad ‘s tool kit. Design methods may associate to analysis, synthesis, determination devising or some other facet of design and can either be independent of subject or engineering, such as originative methods, or subject specific, such as emphasis or thermodynamic analysis. The entire design attack is to the full compatible with the rules of concurrent technology ( Ion, 1995 ) .2.7 ELECTROMYOGRAPHY AND STERNOCLEIDOMASTOID MUSCLEAn electromyography ( EMG ) signal is used to mensurate the myolectrical activity of musculuss. Muscles contractions send a mensurable electric potency that can be recorded by EMG ( Lee et al. , 1995 ) . Surface electromyography ( sEMG ) has been used in research and clinical applications for the non-invasive analysis of c ervix musculuss to supply information about musculoskeletal conditions ( Falla et al. , 2002 ) . Sommerich et Al. ( 2000 ) discusses that at least a few of the musculuss of import for neck motion and stabilisation are accessible with surface electrodes. One of the musculuss is sternocleidomastoid ( SCM ) , where SCM is responsible for flexure, rotary motion and sidelong bending. Figure 2.21 shows the sternocleidomastoid musculus. Sternocleidomastoid musculus Figure 2.21 The sternocleidomastoid musculus ( Wikipedia, 2010 ) . Costa et Al. ( 1990 ) described the authoritative text books of anatomy and kinesiology, see caput motions such as heterolateral rotary motion, homolateral disposition flexure and extension, of import maps of the sternocleidomastoid musculus. The map of the SCM musculus in caput motions of immature persons were studied electromyographically. From the consequences of the research, the caput motions performed by the SCM musculus were classified as heterolateral disposition, lengthiness, extension and flexure. Johnston et Al. ( 2008 ) studied the electromyography signals from the SCM musculus to find differences between computing machine workers with changing degrees of cervix hurting in footings of work stressors, employee strain, EMG amplitude and bosom rate response to assorted undertakings. Assorted surveies ( Ylinen et al. , 2003 ; Bexander et Al. 2005 ; Gabriel et al. , 2004 ; Moon et al. , 2003 ; Lin and Huang, 2008 ) showed that there is a relationship between electromyography ( EMG ) activity of sternocleido mastoideus ( SCM ) musculus and caput rotary motion. The research characterized isometric rotary motion strength in the impersonal and in different pre-rotated places of the cervix. Twenty healthy work forces volunteered as topics. Maximal axial rotary motion strength of the cervix musculuss was measured in a impersonal place and bilaterally at 30A ° and 60A ° rotary motion utilizing the isometric cervix strength measuring system. Isometric maximal voluntary contractions of the cervix musculuss in flexure and extension were tested. The highest strength values were non reached in the impersonal place, but at the largest joint angles, while turning the caput in the opposite way from the pre-rotated place. Maximal strength increased with the increasing angle, and at the 60A ° pre-rotation angle it was 44 % higher towards the right and 27 % higher towards the left compared to the values obtained in the impersonal place. The smallest strength values were besides produced at the largest pre-rotation angles, but in the same way. The con sequences showed a clear relationship between the pre-rotated place of the cervix and maximum voluntary strength in rotary motion ( Ylinen et al. , 2003 ) . Bexander et Al. ( 2005 ) conducted an experiment to look into the consequence of oculus place on neck musculus activity during cervical rotary motion. In the survey, the root-mean-square EMG amplitude was measured for 1 s during the period in which the place of the cervix and caput was held statically in each rotary motion angle ( 0, 15, 30, 45A ° ) . The EMG amplitude of left SCM was increased when the cervix rotate from 0-45A ° during left rotary motion and decreased during right rotary motion. The consequence of experiment indicated that activity of SCM was specific to the way of cervix rotary motion. Moon et Al. ( 2003 ) developed a method to gauge face way angle utilizing both image observation and EMG signal from cervix musculuss. The EMG signal of the SCM musculus concerned in the caput motions is measured. The collarbone part is selected as the mention point for the EMG signal measuring because the collarbone is the nearest bone from cervix and it has no musculuss. During the experiment, when the caput is rotated to the right or left, the EMG signal is measured from the SCM at the opposite side. The consequences from the experiment showed that the alterations of EMG signals are little until 30A ° , but additive belongingss are appeared in the scope [ 30A ° , 90A ° ] . There is a relationship between rotated caput angle and EMG signals. Lin and Huang ( 2008 ) investigated the alterations of cervix musculus activities when utilizing different pillows in a clip series and different sort of pillow. There was a important lessening of SCM activity after 9th proceedingss up to 20th proceedingss when lying down from an unsloped place and non happened to upper cowl muscle musculus. The activities of SCM cervix musculuss decreased when altering craniocervical positions. The consequences confirm the ground of participants preferred proper cervix support. Tilley and Dreyfuss ( 2001 ) conducted human factors research impact everything in day-to-day life. In their measuring on caput rotary motion angle for adult male and adult female as mentioning to Figure 2.22, they defined that the caput confronting front or in 0A ° is the most comfort caput place. From 0A ° to 45A ° is the easy caput rotary motion angle scope and 60A ° is the maximal caput rotary motion angle. 0A ° Most caput comfort 45A ° Easy caput rotary motion 60A ° Max caput rotary motion comfort 45A ° 60A ° Front Figure 2.22 The caput rotary motion angle from top position ( adapted from Tilley and Dreyfuss, 2001 ) .2.8 SummaryLiteratures have provided theoretical theoretical account of siting comfort and uncomfortableness. There are different factors that affected the human comfort during travel, such as force per unit area, quiver, temperature and position. The rider has different degree of comfort and uncomfortableness during air travel. For the bing cervix support during travel, most of the cervix support used by rider is inactive back uping system where the rider needs to set the support when he/she feels uncomfortableness. There is no such adaptative cervix support for current aircraft place. Therefore, the end of this thesis work is to develop a cervix support system that can cut down the cervix musculus emphasis adaptively. There are different attacks that used to understand the comfort and uncomfortableness of sitting objectively every bit good as subjectively. Objective and subjectiv e measuring methods can be combined for measuring both the comfort and uncomfortableness belongingss of seats. Literature reappraisal sing the cervix musculus showed that people need proper cervix support to cut down the cervix uncomfortableness. For this ground, sternocleidomastoid musculus that is responsible of caput rotary motion was selected for the proof of the developed smart cervix support system with surface electromyography methods.

A Struggle for Social & Economic Equality of Black People in America

The struggle for social and economic equality of Black people in America has been long and slow. It is sometimes amazing that any progress has been made in the racial equality arena at all; every tentative step forward seems to be diluted by losses elsewhere. For every â€Å"Stacey Koons† that is convicted, there seems to be a Texaco executive waiting to send Blacks back to the past. Throughout the struggle for equal rights, there have been courageous Black leaders at the forefront of each discrete movement. From early activists such as Frederick Douglass, Booker T. Washington, and W.E.B. DuBois, to 1960s civil rights leaders and radicals such as Martin Luther King, Malcolm X, and the Black Panthers, the progress that has been made toward full equality has resulted from the visionary leadership of these brave individuals. This does not imply, however, that there has ever been widespread agreement within the Black community on strategy or that the actions of prominent Black leaders have met with strong support from those who would benefit from these actions. This report will examine the influence of two â€Å"early era† Black activists: Booker T. Washington and W.E.B. DuBois. Through an analysis of the ideological differences between these two men, the writer will argue that, although they disagreed over the direction of the struggle for equality, the differences between these two men actually enhanced the status of Black Americans in the struggle for racial equality. We will look specifically at the events leading to and surrounding the â€Å"Atlanta Compromise† in 1895. In order to understand the differences in the philosophies of Washington and Dubois, it is useful to know something about their backgrounds. Booker T. Washington, born a slave in 1856 in Franklin County, Virginia, could be described as a pragmatist. He was only able to attend school three months out of the year, with the remaining nine months spent working in coal mines. He developed the idea of Blacks becoming skilled tradesmen as a useful stepping-stone toward respect by the white majority and eventual full equality. Washington worked his way through Hampton Institute and helped found the Tuskeegee Institute, a trade school for blacks. His essential strategy for the advancement of American Blacks was for them to achieve enhanced status as skilled tradesmen for the present, then using this status as a platform from which to reach for full equality later. Significantly, he argued for submission to the white majority so as not to offend the power elite. Though he preached appeasement and a â€Å"hands off† attitude toward politics, Washington has been accused of wielding imperious power over â€Å"his people† and of consorting with the white elite. William Edward Burghardt DuBois, on the other hand, was more of an idealist. DuBois was born in Massachusetts in 1868, just after the end of the Civil War and the official end of slavery. A gifted scholar, formal education played a much greater role in DuBois's life than it did in Washington's. After becoming a Phi Beta Kappa graduate of Fisk and Harvard, he was the first Black to earn a Ph.D. from Harvard in 1895. DuBois wrote over 20 books and more than 100 scholarly articles on the historical and sociological nature of the Black experience. He argued that an educated Black elite should lead Blacks to liberation by advancing a philosophical and intellectual offensive against racial discrimination. DuBois forwarded the argument that â€Å"The Negro problem was not and could not be kept distinct from other reform movements. . .† DuBois â€Å"favored immediate social and political integration and the higher education of a Talented Tenth of the black population. His main interest was in the education of ‘the group leader, the man who sets the ideas of the community where he lives. . .'† To this end, he organized the â€Å"Niagara movement,† a meeting of 29 Black business and professional men, which led to the formation of the National Association for the Advancement of Colored People (NAACP). The crux of the struggle for the ideological center of the racial equality movement is perhaps best exemplified in Mr. DuBois's influential The Souls of Black Folk. In it, he makes an impassioned argument for his vision of an educated Black elite. DuBois also describes his opposition to Booker T. Washington's â€Å"Atlanta Compromise† as follows: â€Å"Mr. Washington represents in Negro thought the old attitude of adjustment and submission†¦Ã¢â‚¬  According to DuBois, Washington broke the mold set by his predecessors: â€Å"Here, led by Remond, Nell, Wells- Brown, and Douglass, a new period of self-assertion and self- development dawned†¦. But Booker T. Washington arose as essentially the leader not of one race but of two–a compromiser between the South, the North, and the Negro.† DuBois reported that Blacks â€Å"resented, at first bitterly, signs of compromise which surrendered their civil and political rights, even though this was to be exchanged for larger chances of economic development.† DuBois's point and, according to him, the collective opinion of the majority of the Black community, was that self- respect was more important than any potential future economic benefits. Before Washington's conciliatory stance gained a foothold, â€Å"the assertion of the manhood rights of the Negro by himself was the main reliance.† In other words, DuBois resented what he saw as Washington â€Å"selling† Black pride: â€Å"†¦Mr. Washington's programme naturally takes an economic cast, becoming a gospel of Work and Money to such an extent as apparently almost completely to overshadow the higher aims of life.† The compromise included, in DuBois's words, â€Å"that black people give up, at least for the present, three things,– â€Å"First, political power, Second, insistence on civil rights, Third, higher education of Negro youth,–and concentrate all their energies on industrial education, the accumulation of wealth, and the conciliation of the South.† The final point comprised the centerpiece both of Washington's strategy for the ultimate redemption of Black Americans and of DuBois's condemnation of that strategy. Indeed, Washington backed up his assertions by founding the Tuskeegee Institute as a trade school for young Black men. DuBois could not abide this type of appeasement. In his mind, this step was tantamount to the Black community telling the white community that, henceforth, Blacks would cease pretending to be equal to whites as human beings; rather, they would accept an overtly inferior social status as being worthy of maintaining the white majority's physical world, but unworthy of true equality, of conducting socio-cultural discourse with the mainstream society. The paradox must have been maddening for both men, especially Mr. Washington. He no doubt understood that, as a group, Blacks could never hope to progress to the point of equality from their position of abject poverty. Moreover, without skills, their hopes of escaping their economic inferiority were indeed scant. Washington's plan for blacks to at least become skilled artisans and tradesmen must have seemed logical to him from the standpoint of improving the economic lot of the average Black man. At the same time, he must have realized that, by accepting inferiority as a de- facto condition for the entire race, he may have broken the black spirit forever. In considering this matter, the writer is reminded of more recent events in American history–the affirmative action flap that occurred after Clarence Thomas's appointment to the U.S. Supreme Court, for example. Mr. Thomas, clearly a beneficiary of affirmative action, announced that he was nonetheless opposed to it. His argument was that if he had not been eligible for benefits under affirmative action programs, he would have still achieved his current position in the inner circle of this society's white power elite. Similarly, Booker T. Washington enjoyed access to the power elite of his time, but one must wonder whether President Roosevelt, for example, in his interactions with Mr. Washington, was not merely using the situation for public relations value. â€Å"[Mr. Washington] was ‘intimate' with Roosevelt from 1901 to 1908. On the day Roosevelt took office, he invited Washington to the White House to advise him on political appointments of Negroes in the south.† After all, he did not become a popular president by being oblivious to such political maneuvering. Perhaps Mr. DuBois was the more prescient visionary. Perhaps he understood what Mr. Washington did not, that after the critical historical momentum toward social acceptance that had been established prior to the late nineteenth century, if political pressure were not maintained, the cause of true equality would be lost forever. Moreover, DuBois understood that equality would not be earned through appeasement. From our perspective of over 100 years, we must admit that he may have been right. For example, in the aftermath of the â€Å"Atlanta Massacre† of September 22, 1906 and a similar incident in Springfield, Illinois, â€Å"it was clear to almost all the players that the tide was running strongly in favor of protest and militancy.† â€Å"For six days in August, 1908, a white mob, made up, the press said, of many of the town's ‘best citizens,' surged through the streets of Springfield, Illinois, killing and wounding scores of Blacks and driving hundreds from the city.† However, it later turned out that DuBois was considered to be too extreme in the other direction. For example, as the NAACP became more mainstream, it became increasingly conservative, and this did not please DuBois, who left the organization in 1934. He returned later but was eventually shunned by Black leadership both inside and outside of the NAACP, especially after he voiced admiration for the USSR. In the political climate of the late 1940s and 1950s, any hint of a pro-communist attitude–black or white–was unwelcome in any group with a national political agenda. We can see, then, that neither Washington's strategy of appeasement nor DuBois's plan for an elite Black intelligentsia was to become wholly successful in elevating American Blacks to a position of equality. However, perhaps it was more than the leadership of any one Black man that encouraged African Americans to demand a full measure of social and economic equality. Perhaps the fact that there was a public dialogue in itself did more to encourage Black equality than the philosophy of any one prominent Black man. After all, concepts such as equality are exactly that: concepts. As such, it up to each of us to decide how we see ourselves in relation to others; superior or inferior, equal or not equal, the choice is ultimately our own.
