Sir Gawain And The Green Knight The Role Of Women Essays

Sir Gawain and the Green Knight: The Role of Women Sir Gawain and the Green Knight: The Role of Women In the fourteenth century, chivalry was in decline due to drastic social and economic changes. Although feudalism-along with chivalry-would eventually fall for other reasons, including a decrease in cheap human resources due to a drop in population caused by plague epidemics and the emergence of a mercantile middle class, the Gawain author perceived a loss of religious values as the cause of its decline. Gawain and the Green Knight presents both a support of the old feudal hierarchies and an implicit criticism of changes by recalling chivalry in its idealized state in the court of King Arthur. The women in the story are the poet's primary instruments in this critique and reinforcement of feudalism. The poet uses the contrast between the Virgin Mary with Lady Bertilak's wife to point out the conflict between courtly and spiritual love that he felt had weakened the religious values behind chivalry. The poem warns that a loss of the religious values behind chivalry would lead to its ultimate destruction. Although superficially Sir Gawain and the Green Knight appears to be a romantic celebration of chivalry, it contains wide-ranging serious criticism of the system. The poet is showing Gawain's reliance on chivalry's outside form and substance at the expense of the original values of the Christian religion from which it sprang. The first knights were monastic ones, vowing chastity, poverty and service to God, and undertaking crusades for the good of their faith. The divergence between this early model and the fourteenth century knight came with the rise of courtly love in which the knights were led to their great deeds by devotion to a mistress rather than God. The discrepancy between this and the church's mistrust of women and desires of the flesh is obvious, and the poet uses women in the story to deliver this message. In contrast to reality at the time, women in the story are given great power: Mary, when properly worshiped, gives Gawain his power, Lady Bertilak operates alone in the bedroom and singlehandedly taints the chevalier, and Morgan the Fay instigates the entire plot, wielding enough power. The author is using them as a metaphor for other anti-social forces and dangers outside the control of feudalism and chivalry, drawing upon biblical and classical examples in his audience's minds of where femininity is linked with subversiveness. Lady Bertilak is clearly seen in the Biblical role of the temptress, the Eve who led Adam astray--in Gawain, she represents the traditional female archetypes of courtly love, disobedience, lust and death. Eve's antithesis is the Virgin Mary, who is the only women who achieves motherhood while maintaining her chastity; she represents spiritual love, obedience, chastity, and life That Gawain is Mary's Knight is made clear as he is robed for battle; the pentangle represents the five joys of Mary, and he has "that queen's image / Etched on the inside of his armored shield" (648-649). As long as he is solely focused on his quest for the Green Knight, he derives his prowess and courage from his special relationship with Mary. On his journey to look for the Green Knight he is beset by a number of hardships, and is finally brought to the point of despair. Alone and freezing in the forest, he prays to Mary for shelter and a place to say mass on Christmas Eve. She answers his prayers and leads him to Bertilak's castle; however, his arrival at Bertilak's court throws him into a totally different world. Here, Gawain impresses courtiers of Bertilak's castle with his prowess in the field of courtly love rather than the feats of daring or his upholding of his honor, traits that would draw compliments in Arthur's court. Camelot is portrayed in its youth, long before it too is tainted by Lancelot and courtly love; Arthur is young, "child-like (86)" and the "fine fellowship [of Camelot] was in its fair prime." The analogy is obvious: Arthur's court embodies chivalry's pure roots, where martial exploits were the primary subject of interest, whereas Bertilak's castle represents the low point of the degeneration the poet perceives chivalry to have undergone. The Lady's association with courtly love also ties this aspect of chivalry with degeneration and sin. Immediately upon his arrival in Bertilak's court, the separation between courtly love religion is clear: Gawain at Mass is "in serious mood the whole service through"(940). This serious mood is immediately forgotten with the sight of the Lady, whom he immediately focuses on at the expense of

Burning Mississippi essays

Burning Mississippi essays The film Burning Mississippi was based on the prejudice acts towards the African Americans in the south and in this case Mississippi. The time was in the 50s an 60s during the period of the Ku Klux Klan. The reason for these acts of hate was because the white men thought that they where the only race that mattered and the African Americans where the scum of society. In the movie it shows how even the law was out to get the African Americans, because when ever the KKK did something such as burning down houses and lynching negros they would just sit back and not step in and do anything about it. To prove that I want to tell you about the first scene that happened in the movie. There was three males driving on the road at night time and they were approached by three other cars and, the three males didnt no who they were so they pulled and it was two police man and a few other men. Well the three men in the car were a negro and two white males, all three were shot dead by the po lice men because he didnt think that white males should talk or even be seen with a negro. These white males where considered negro lovers. The very first image that sticks in your mind is the officer putting his gun to the boys head and pulling the trigger. This shows how savage they are. There are many characters in this film, there are all the F.B.I agents trying to find the three boys then the police, towns people, African Americans, and Clayton the police mans wife. The theme of this story shows how destructive mankind can be towards one another. I do not agree with the theme of this story because I dont think that mankind should destroy one another, no matter how we dont like other we shouldnt destroy each other. I think Hollywood did a good job on making this accurate to how it was back in the day. They really went into depth to show how it reall ...

Previous studies on fundamental and technical analysis framework has created sizeable prove on their respective capabilities to discuss the arena of stock prices or to predict future variation of the share value. Despite this achievement, the literature has been silent on developing a reliable approach of integrating both technical and fundamental analysis methods in determining equity valuation as well as reaching to an investment decision. The current study utilizes fused fundamental framework whereby objective analysis of the share value is integrated with the technical analysis of the past returns and value in the stock market. More specifically, the report focused on the share values in banks, supermarket, telecommunication companies and RandGold Resource limited. The technical information in UK stocks has been utilized frequently by the investors to make decision pertaining which industry they should invest in. Generally, the technical information focuses on the shares’ price over a short term as well as the returns attained from sale volume information. Even when the stock price strays, the arbitrager can end up acquiring excess simultaneous returns in the market. A notable business research based on technical information in the UK stock price is the momentum investment approach (Konecny, 2013, p. 175). Along with the increase of the abnormal phenomena, attempted exploration on feasibilities of UK stock market anomalies stretch out to shaping investment behavior on account of the financial capacity. For instance, the investor applies heuristics to cement subjective marks and regarded as crucial decision criteria to attain abnormal

Development of Sustainable Water Management System

Development of Sustainable Water Management System 1.0 Introduction A regeneration project close to Bedford will see the construction of a hotel and a school, with both intended to be sustainable. Hunt et al. (2006) judge a developments sustainability based upon its impact upon the local environment, its cost effectiveness, both during and after construction, and also its impact upon society. These factors tend to relate, to varying degrees on different projects, to how sustainable the developments water usage is. Taking this into account, those designing and building the school and the hotel have put considerable time and effort into ensuring that the projects water management setup is from the very top of the line. The following report focuses on the design and implementation of the regeneration projects water management system, calculating the respective quantities of water required for the school and for the hospital to run effectively and evaluating the alternative green solutions available to ensure efficient use of water in the two buildings. Among the green technologies looked at, consideration will be given to collection, storage and usage of rainwater to supplement the water supply sourced from utilities companies. Recycled grey water will also be discussed as a possible means of saving water. Lastly, the report will look into methods of conserving water, explaining how they would be implemented and how effective they would be if utilised on this particular project. 2.0 Description of the Regeneration Project The school that is being constructed will be co-ed and will enrol up to 150 students, catering to children between the ages of six and twelve years old. The school will have a staff of sixteen: eight on full-time contracts, two providing maintenance services and the rest working on a part-time basis. The hotel that is being built will consist of fifty double-rooms and will take on four members of staff on a full-time basis. The schools roof will be made from pitched tiles, taking up approximately 385 m ­2, and approximately 600 m2 of smooth surface. The hotels roof will also be made from pitched tiles, but with no smooth surface. It will take up approximately 1,200 m2. 3.0 Estimating water requirements for the school and the hotel In order to come up with a water strategy, the water requirements of the two buildings must first be approximated. Bradford (2007) notes that for different kinds of end users, there are a variety of purposes that water can be used for, giving the example of the dissimilarity in the water usage patterns of domestic users compared with agricultural users. 3.1 Water requirements for the school The figures in Table 3.1 calculate the schools overall water consumption as being at 720 m3/year. Figure 3.1 breaks down the schools water consumption categorically, displaying the main uses to which water is put in terms of quantity. Flushing toilets takes up the largest proportion (36%) of water consumption (see Figure 3.1). 3.2 Water requirements for the hotel Hunt et al. (2006) note that there is great variation in the use of water at hotels. What consumption patterns there are tend to relate to water usage by the hotels guests, the presence or absence of a hotel swimming pool and the hotels star rating. As there is insufficient data regarding the hotels star rating and water consumption, a water usage estimate of 30 m3/bed space/year is made, as this is displayed in Table 3.2 (Waggett and Arotsky, 2006) to be the typical consumption in hotels without a rating that do not have swimming pools. With the average requirement of water estimated at 30 m3/bed space/year and with a total of fifty double-rooms, total demand can be approximated to be = 30*50*2 = 3000 m3. Hotels use their water supply for bathing, flushing toilets, drinking, cooking, cleaning and gardening. With no data available which can be used to break down water usage into its constituent elements, this is estimated using average UK domestic use (see Figure 3.2) and modified UK hotel use, based on single occupants (see Figure 3.2). 4.0 Non-potable water supply options for the school and the hotel Hastings (2006) differentiates between water that is fit for drinking, known as à ¢Ã¢â€š ¬Ã‹Å"potable water, and à ¢Ã¢â€š ¬Ã‹Å"non-potable water which, while it is not fit for ingestion, may still be utilised to flush toilets, for cleaning vehicles, buildings or clothes (in washing machines) or to irrigate land. While all non-potable water fails to meet the minimum required standards for drinking water, Hastings makes a further distinction between treated non-potable water, known as green water, and untreated non-potable water, referred to as grey water. 4.1 Rainwater harvesting (RH) The EA (2003) notes that rainwater collection may occur by gathering the water from roofs or from hard surfaces such as roads using down pipes (see Figure A-1 in the Appendix). The rainwater gathered can be utilised for any number of non-potable water uses. An approximation will be made here of the expected rainwater harvest from the two buildings being constructed. The rainwater harvests quality varies with elements from outside, like the amount of leaves or bird droppings contaminating the harvest. The impact of these elements can be lessened with the use of a protective filter to cover the rainwater outlet (Cornwall Energy Efficiency Advice Centre, 2007). The EA (2003) also notes that rainwater is of a good enough standard to not need treatment after it has been collected, before it can be used. The gathered water will be kept in an over-ground plastic tank, with its placement selected so as to minimise bacteria growth in hot weather, while also minimising frost when the weather is cold. Line filters will also be put in place. With the right choice of filter and of placement, bad smells and water discolouration can be lessened. 4.1.1 Determination of the quantity of gatherable rainwater for the hotel and The school Accurately calculating the best quantity of gatherable rainwater for the two buildings calls for a plan of the roofs catchment areas and also for rainfall data relating to the local area (see Figure 4.1) (covering the previous 20 years) It is not possible to gather all of the rain that falls on the buildings and transfer it to the plastic container in its entirety. Usually, rainfall harvests lose something in the region of 10%-60% of the water, varying with the kind of roof in question, the drainage coefficient of the material it has been made from (see Table 1) and the filter efficiency: always à ¢Ã¢â€š ¬Ã…“0.9à ¢Ã¢â€š ¬?. It is also possible to lose rainwater if the container it collects in overflows due to heavy rainfall or low water usage (ibid, 2003). Table 4.1: Drainage coefficient for different roof types Roof type Runoff coefficient Pitched roof tiles 0.75 0.9 Flat roof with smooth tiles 0.5 Flat roof with gravel layer 0.4 0.5 (Source: EA, 2003) Based on the aforementioned data, it is possible to work out the potential rainfall harvest in a particular location by inputting the data into this formula (EA, 2008): Q = AAR x TCA x RC x FC where Q = Annual Gatherable Rainfall (litres) AAR = Annual Average Rainfall (mm/yr) TCA = Total Catchment Area (m2) RC = Runoff Coefficient FC = Filter Coefficient 1. For the school As, logically, a larger roof will allow for the collection of a greater quantity of rainwater, it is important to be aware of the roof area. The roof surface areas and their construction materials are: Pitched roof tiles 600 m2 Flat roof (smooth surface) 385 m2 According to Table 4.1, the minimum possible RC for pitched roof tiles is 0.75, while the RC for smooth surface roofs is 0.5 AAR = Annual Average Rainfall (mm/yr) =à ¢Ã‹â€ Ã¢â‚¬Ëœ Average Rainfall (mm) for the 12 Month period illustrated by Figure 4.1 = 573mm The Annual Collectable Rainfall (litres), Q = ((600 m2 X (573 mm) X 0.75) + (385 m2 X (573 mm) X 0.5)) X 0.9 = 331,337.25 litres per annum. = 331.34 m3 per annum. This is a lower value than that of the predicted total annual water demand for the school. 2. For the hotel The hotels roof area is 1,200 m2, entirely made from pitched roof tiles. Q = 1,200 X 573 X 0.75 X 0.9 = 464,130 litres per annum = 464.13 m3per annum. This value also falls below predicted annual water demand for the hotel. Table A-1 (see Appendix A) approximates the monthly rainfall harvest for the two buildings, using the aforementioned equation and using the RC of pitched roof tiles. The figures for the predicted rainfall harvest and the predicted water requirements point to a shortfall in the ability of the rainwater to fulfil the projects water requirements. However, the rainwater may still play a significant role, perhaps covering the two buildings toilet flushing needs, for instance. 4.1.2 Sizing the storage tank in the RH system for the two buildings The EA (2003) notes that the storage tanks purchase price is the most expensive element of setting up the RH system and so deciding upon the right size for it is very important. The biggest tank will not necessarily be the most efficient in the long run and so it is important to work out the optimal size, so that the buildings can harvest sufficient rainwater without overspending. The quantity of water that is kept in the tank should ideally approach the quantity that is required to service the two buildings. The choice of tank must account for price, size and a minimum of two water overflows each year, in order to get rid of unwanted objects in the tank-water. The project planners may also want to invest in a first flush device (Well, 2003) to ensure that the initial water flow, which will contain debris that has collected on the roof, does not enter the tank, keeping its contents relatively clean. The makers and retailers of the rainfall harvest setup will have means of determining the best tank size for the project. In fact, some of them have applications available for visitors to their websites to work out the optimum size for their needs (e.g. Klargesters Envireau products, available at www.klargester.com) and these are handy for making an initial estimate of how much they need to spend. It is best for the planners to go on to discuss this choice with experts in this area. Figure 4.2: Water balance for approximation of rainwater storage capacity The EA (2003) notes that the capacity needed will vary according to elements including rainfall patterns, catchment areas, demand patterns, retention time, cost of parts and the cost of and access to alternative supplies. The Development Technology Unit (2008) also states that the level of capacity needed will be based upon several elements, such as weather and rain data, roof surface area, RC and data regarding the number of consumers and the amount of water they use on average. It goes on to suggest several means of setting the size of system parts: Method 1 the demand-side approach (see Appendix A). Method 2 calculating the size of the tank based on elements such as storage capacity, overflow and drainage (the supply-side approach) (see Appendix A). Method 3 computer model (see Appendix A). The methods differ in terms of how sophisticated and how complex they are. Some of them can easily be undertaken by people without specialist knowledge, whereas some need specialists familiar with complicated software. The major elements contributing to the method selected include: the size and the complexity of the system and its parts the availability of the components that are necessary to operate using a specific method (e.g. computers) the required skills and technical knowledge/training among the practitioners/designers. Also, according to the EA (2008), tank size tends to be based upon either the capacity required for 18 days or a 5% share of the annual yield (whichever of the two is lower). This method will be combined with the supply-side method to determine the tank capacity for this project (see Appendix A). 1. Calculating the optimal tank size based upon the predicted rain yield: The EA (2003) formula for working out the best tank capacity for the rainfall harvest setup is as follows: Tank capacity (litres) = Roof area (m2) x drainage factor x filter efficiency x annual rainfall (mm) x 0.05 For the school Optimal tank capacity (litres) = (600* 0.75* 0.9* 573 mm*0.05) + (385*0.5* 0.9* 573 mm*0.05) = 16566.86 litres = 16.57 m3 For the hotel Optimal tank capacity (litres) = (1,200* 0.75* 0.9* 573 mm*0.05) = 23206.5 litres = 23.21 m3 2. Calculating the optimal tank capacity using the idea of holding 18days- worth of demand: Collection tank volume = days storage x average daily demand For the school The à ¢Ã¢â€š ¬Ã‹Å"Estimating water demands for the hotel and school section and the figures in Chapter 3 show that the overall quantity of water used to flush toilets, irrigate soil and clean is 612 m3 per annum for the school building. This exceeds the estimated annual rainfall harvest. This being the case, the RH tank will provide water for flushing toilet, with the tank storage for 18 days equalling: (268 m3/365 days)*(18 days) = 13.22 m3 For the hotel According to the figures in Chapter 3, the overall average water requirement at the hotel is 3000 m3. The quantity used to flush toilets, irrigate soil and clean amounts to roughly 53% of the hotels water requirement: roughly 1590 m2 per annum. This requirement cannot be covered in total by the RH alone. This being the case, the RH will be limited to cleaning and/or irrigating or to flushing toilets. Even within these limitations, there may not be sufficient rainwater for these tasks. Using the average daily requirement for toilet flushing: the tank storage = (3000 x 0.35) m3/365days x 18 = 51.79 m3 Using the average daily requirement for cleaning or irrigating: the tank storage = (3000 x (0.12 + 0.06)) m3/365days x 18 = 26.63 m3 Using the aforementioned EA (2003) data, a smaller size is optimal. This being the case, if the RH is used to flush toilets, the respective tank sizes for the hotel and the school are going to be 23 m3 and 14 m3. If the method of estimation used is the supply-side method (i.e. it is based upon capacity, overflow and drainage (see the tdix A)), the the optimal respective tank sizes for the hotel and the school will be 35 m3recomm3 m3 and 35 m3ing for these figures is represented bycalculations ad A-3 (seein Appendix A)The selection ultimately made may depend on a combination of these methods of calculation, as well as the price of the tankAfter this, th 4.2 Grey water recycling at the school and the hotel Metcalf and Eddy (1991) refer to two kinds of wastewater. These are grey and black wastewater. Black water has been flushed down toilets, passed through the drainage system and on to treatment plants. Black water is contaminated with more pollutants than grey water. Grey water accounts for all of the wastewater which has not been used to flush toilets (EA, 2003). It can be treated and then reused for flushing toilets or irrigating soil (Metcalf and Eddy, 1991). Both Waggett (2004) and the EA (2008) refer to grey water from washing machines, kitchen sinks and dishwashers as black wastewater, as it is heavily contaminated and can contain large amounts of grease and food particles. Figures 3.1 and 3.3 illustrate that the two buildings will produce grey water at the levels of 55% at the hotel and 32% at the school, 32% and al.

These factors are referred to as the pillars of sustainable development (Hunt and Rogers, 2005). This part of the report evaluates the potential methods for decreasing the buildings water requirements in terms of their impact upon the aforementioned pillars of sustainable development. The cost effectiveness of the options If less water is required, then less money will be spent on sewage treatment and savings will also be made in terms of spending on water (Otterpohl, 2006). The savings on water will not necessarily be very large, as UK water prices are not high. The savings made by implementing the green technologies would need to be set against the cost of their implementation in order to work out how long it would take for them to financially justify the expenditure. The necessary predictions of expected usage would be difficult to make, particularly for the school building, which would have very low usage during holiday periods. In the case of the school, grey water would probably not be cost effective (as discussed earlier) and would probably need a very long time to make sufficient savings to cover is not co2003) estimate a 30% saving on water expenditure is needed to justify investment in the reuse of grey water and it is unlikely that this would be achieved at the schoolMoreover, at the se kitchen eyecyclis Grey water would, however, be cost effective in hotels; especially big hotels with en-suite accommodation, as customers would consume large quantities of water systems afihite bathrooms and powerful showers an expected part of modern hotels, water consumption is actually higher in the newer establishments, making recycling of non-potable water even more relevantUnlike the majoritutilise treated grey water for toilet flushing when it is busy and revert to its main supply when there are few customer, in order to avoid keeping the grey water in their tank for extended periods. This is common practice in countries with low rainfallrefore, greywatergrey water is The extra setup required to circulate the treated grey water around the hotel would need significant expenditure from those funding the project and this would have to be given serious thought before deciding whether it would pay off in the long term. Rain harvesting setups are fairly commonplace at UK schools, as the water is considered to be fairly clean and the running costs are not too. With a lot of water used for toilet flushing, there would be a need for a big tank at the school, which could lead to a big saving over. To carry out a similar harvesting operation, the hotel would require both a large harvesting area (on the roof) and sufficient room to keep the tank. This would probably not be workable for most hotels. Establishments with swimming pools might consider harvesting and treating water to use in their pool. Social costs The costs to society of these solutions would take the form of problems with their acceptability and/or their reliability (Hunt et al., 2006) (see Appendix C). Environmental costs Braithwaite (2006) views sustainability and environmental protection as being more or less the same thing, with an emphasis upon ensuring that the construction and the running of the buildings is not damaging to the local area going forward. To ensure this does not happen, evaluation of the likely negative externalities of the technologies put forward is needed. Water sustainability for the project might be measured in terms of factors such as impact on the climate, biological diversity and resource depletion.

The recommended technologies need to be beneficial in terms of future sustainability, with emphasis placed on decreasing both the quantity of water that is wasted and the quantity that is obtained from the mains source. Integrated costs On most projects, planners would tend to opt for familiar solutions that are known to be effective over new ones which they might perceive as inherently risky and this might be a factor in the selection made here, particularly in the case of the school, given consideration of the involvement of children (Hunt et al., 2006). As well as the interests of the planners and developers, it is important perhaps most important to give consideration to how the solutions would impact upon the people ultimately using the facilities being discussed. With no official standards for the condition required of non-potable water before it can be used, careful planning is needed to make certain that no errors are made that could potentially cause harm to customers or students. Hotels often take the precaution of labelling water sources such as sinks that provide non-potable water. Another precaution, which might be made use of at the school, would be to use quality gpes (EA, 2008).

Development of Sustainable Water Management System Development of Sustainable Water Management System 1.0 Introduction A regeneration project close to Bedford will see the construction of a hotel and a school, with both intended to be sustainable. Hunt et al. (2006) judge a developments sustainability based upon its impact upon the local environment, its cost effectiveness, both during and after construction, and also its impact upon society. These factors tend to relate, to varying degrees on different projects, to how sustainable the developments water usage is. Taking this into account, those designing and building the school and the hotel have put considerable time and effort into ensuring that the projects water management setup is from the very top of the line. The following report focuses on the design and implementation of the regeneration projects water management system, calculating the respective quantities of water required for the school and for the hospital to run effectively and evaluating the alternative green solutions available to ensure efficient use of water in the two buildings. Among the green technologies looked at, consideration will be given to collection, storage and usage of rainwater to supplement the water supply sourced from utilities companies. Recycled grey water will also be discussed as a possible means of saving water. Lastly, the report will look into methods of conserving water, explaining how they would be implemented and how effective they would be if utilised on this particular project. 2.0 Description of the Regeneration Project The school that is being constructed will be co-ed and will enrol up to 150 students, catering to children between the ages of six and twelve years old. The school will have a staff of sixteen: eight on full-time contracts, two providing maintenance services and the rest working on a part-time basis. The hotel that is being built will consist of fifty double-rooms and will take on four members of staff on a full-time basis. The schools roof will be made from pitched tiles, taking up approximately 385 m ­2, and approximately 600 m2 of smooth surface. The hotels roof will also be made from pitched tiles, but with no smooth surface. It will take up approximately 1,200 m2. 3.0 Estimating water requirements for the school and the hotel In order to come up with a water strategy, the water requirements of the two buildings must first be approximated. Bradford (2007) notes that for different kinds of end users, there are a variety of purposes that water can be used for, giving the example of the dissimilarity in the water usage patterns of domestic users compared with agricultural users. 3.1 Water requirements for the school The figures in Table 3.1 calculate the schools overall water consumption as being at 720 m3/year. Figure 3.1 breaks down the schools water consumption categorically, displaying the main uses to which water is put in terms of quantity. Flushing toilets takes up the largest proportion (36%) of water consumption (see Figure 3.1). 3.2 Water requirements for the hotel Hunt et al. (2006) note that there is great variation in the use of water at hotels. What consumption patterns there are tend to relate to water usage by the hotels guests, the presence or absence of a hotel swimming pool and the hotels star rating. As there is insufficient data regarding the hotels star rating and water consumption, a water usage estimate of 30 m3/bed space/year is made, as this is displayed in Table 3.2 (Waggett and Arotsky, 2006) to be the typical consumption in hotels without a rating that do not have swimming pools. With the average requirement of water estimated at 30 m3/bed space/year and with a total of fifty double-rooms, total demand can be approximated to be = 30*50*2 = 3000 m3. Hotels use their water supply for bathing, flushing toilets, drinking, cooking, cleaning and gardening. With no data available which can be used to break down water usage into its constituent elements, this is estimated using average UK domestic use (see Figure 3.2) and modified UK hotel use, based on single occupants (see Figure 3.2). 4.0 Non-potable water supply options for the school and the hotel Hastings (2006) differentiates between water that is fit for drinking, known as à ¢Ã¢â€š ¬Ã‹Å"potable water, and à ¢Ã¢â€š ¬Ã‹Å"non-potable water which, while it is not fit for ingestion, may still be utilised to flush toilets, for cleaning vehicles, buildings or clothes (in washing machines) or to irrigate land. While all non-potable water fails to meet the minimum required standards for drinking water, Hastings makes a further distinction between treated non-potable water, known as green water, and untreated non-potable water, referred to as grey water. 4.1 Rainwater harvesting (RH) The EA (2003) notes that rainwater collection may occur by gathering the water from roofs or from hard surfaces such as roads using down pipes (see Figure A-1 in the Appendix). The rainwater gathered can be utilised for any number of non-potable water uses. An approximation will be made here of the expected rainwater harvest from the two buildings being constructed. The rainwater harvests quality varies with elements from outside, like the amount of leaves or bird droppings contaminating the harvest. The impact of these elements can be lessened with the use of a protective filter to cover the rainwater outlet (Cornwall Energy Efficiency Advice Centre, 2007). The EA (2003) also notes that rainwater is of a good enough standard to not need treatment after it has been collected, before it can be used. The gathered water will be kept in an over-ground plastic tank, with its placement selected so as to minimise bacteria growth in hot weather, while also minimising frost when the weather is cold. Line filters will also be put in place. With the right choice of filter and of placement, bad smells and water discolouration can be lessened. 4.1.1 Determination of the quantity of gatherable rainwater for the hotel and The school Accurately calculating the best quantity of gatherable rainwater for the two buildings calls for a plan of the roofs catchment areas and also for rainfall data relating to the local area (see Figure 4.1) (covering the previous 20 years) It is not possible to gather all of the rain that falls on the buildings and transfer it to the plastic container in its entirety. Usually, rainfall harvests lose something in the region of 10%-60% of the water, varying with the kind of roof in question, the drainage coefficient of the material it has been made from (see Table 1) and the filter efficiency: always à ¢Ã¢â€š ¬Ã…“0.9à ¢Ã¢â€š ¬?. It is also possible to lose rainwater if the container it collects in overflows due to heavy rainfall or low water usage (ibid, 2003). Table 4.1: Drainage coefficient for different roof types Roof type Runoff coefficient Pitched roof tiles 0.75 0.9 Flat roof with smooth tiles 0.5 Flat roof with gravel layer 0.4 0.5 (Source: EA, 2003) Based on the aforementioned data, it is possible to work out the potential rainfall harvest in a particular location by inputting the data into this formula (EA, 2008): Q = AAR x TCA x RC x FC where Q = Annual Gatherable Rainfall (litres) AAR = Annual Average Rainfall (mm/yr) TCA = Total Catchment Area (m2) RC = Runoff Coefficient FC = Filter Coefficient 1. For the school As, logically, a larger roof will allow for the collection of a greater quantity of rainwater, it is important to be aware of the roof area. The roof surface areas and their construction materials are: Pitched roof tiles 600 m2 Flat roof (smooth surface) 385 m2 According to Table 4.1, the minimum possible RC for pitched roof tiles is 0.75, while the RC for smooth surface roofs is 0.5 AAR = Annual Average Rainfall (mm/yr) =à ¢Ã‹â€ Ã¢â‚¬Ëœ Average Rainfall (mm) for the 12 Month period illustrated by Figure 4.1 = 573mm The Annual Collectable Rainfall (litres), Q = ((600 m2 X (573 mm) X 0.75) + (385 m2 X (573 mm) X 0.5)) X 0.9 = 331,337.25 litres per annum. = 331.34 m3 per annum. This is a lower value than that of the predicted total annual water demand for the school. 2. For the hotel The hotels roof area is 1,200 m2, entirely made from pitched roof tiles. Q = 1,200 X 573 X 0.75 X 0.9 = 464,130 litres per annum = 464.13 m3per annum. This value also falls below predicted annual water demand for the hotel. Table A-1 (see Appendix A) approximates the monthly rainfall harvest for the two buildings, using the aforementioned equation and using the RC of pitched roof tiles. The figures for the predicted rainfall harvest and the predicted water requirements point to a shortfall in the ability of the rainwater to fulfil the projects water requirements. However, the rainwater may still play a significant role, perhaps covering the two buildings toilet flushing needs, for instance. 4.1.2 Sizing the storage tank in the RH system for the two buildings The EA (2003) notes that the storage tanks purchase price is the most expensive element of setting up the RH system and so deciding upon the right size for it is very important. The biggest tank will not necessarily be the most efficient in the long run and so it is important to work out the optimal size, so that the buildings can harvest sufficient rainwater without overspending. The quantity of water that is kept in the tank should ideally approach the quantity that is required to service the two buildings. The choice of tank must account for price, size and a minimum of two water overflows each year, in order to get rid of unwanted objects in the tank-water. The project planners may also want to invest in a first flush device (Well, 2003) to ensure that the initial water flow, which will contain debris that has collected on the roof, does not enter the tank, keeping its contents relatively clean. The makers and retailers of the rainfall harvest setup will have means of determining the best tank size for the project. In fact, some of them have applications available for visitors to their websites to work out the optimum size for their needs (e.g. Klargesters Envireau products, available at www.klargester.com) and these are handy for making an initial estimate of how much they need to spend. It is best for the planners to go on to discuss this choice with experts in this area. Figure 4.2: Water balance for approximation of rainwater storage capacity The EA (2003) notes that the capacity needed will vary according to elements including rainfall patterns, catchment areas, demand patterns, retention time, cost of parts and the cost of and access to alternative supplies. The Development Technology Unit (2008) also states that the level of capacity needed will be based upon several elements, such as weather and rain data, roof surface area, RC and data regarding the number of consumers and the amount of water they use on average. It goes on to suggest several means of setting the size of system parts: Method 1 the demand-side approach (see Appendix A). Method 2 calculating the size of the tank based on elements such as storage capacity, overflow and drainage (the supply-side approach) (see Appendix A). Method 3 computer model (see Appendix A). The methods differ in terms of how sophisticated and how complex they are. Some of them can easily be undertaken by people without specialist knowledge, whereas some need specialists familiar with complicated software. The major elements contributing to the method selected include: the size and the complexity of the system and its parts the availability of the components that are necessary to operate using a specific method (e.g. computers) the required skills and technical knowledge/training among the practitioners/designers. Also, according to the EA (2008), tank size tends to be based upon either the capacity required for 18 days or a 5% share of the annual yield (whichever of the two is lower). This method will be combined with the supply-side method to determine the tank capacity for this project (see Appendix A). 1. Calculating the optimal tank size based upon the predicted rain yield: The EA (2003) formula for working out the best tank capacity for the rainfall harvest setup is as follows: Tank capacity (litres) = Roof area (m2) x drainage factor x filter efficiency x annual rainfall (mm) x 0.05 For the school Optimal tank capacity (litres) = (600* 0.75* 0.9* 573 mm*0.05) + (385*0.5* 0.9* 573 mm*0.05) = 16566.86 litres = 16.57 m3 For the hotel Optimal tank capacity (litres) = (1,200* 0.75* 0.9* 573 mm*0.05) = 23206.5 litres = 23.21 m3 2. Calculating the optimal tank capacity using the idea of holding 18days- worth of demand: Collection tank volume = days storage x average daily demand For the school The à ¢Ã¢â€š ¬Ã‹Å"Estimating water demands for the hotel and school section and the figures in Chapter 3 show that the overall quantity of water used to flush toilets, irrigate soil and clean is 612 m3 per annum for the school building. This exceeds the estimated annual rainfall harvest. This being the case, the RH tank will provide water for flushing toilet, with the tank storage for 18 days equalling: (268 m3/365 days)*(18 days) = 13.22 m3 For the hotel According to the figures in Chapter 3, the overall average water requirement at the hotel is 3000 m3. The quantity used to flush toilets, irrigate soil and clean amounts to roughly 53% of the hotels water requirement: roughly 1590 m2 per annum. This requirement cannot be covered in total by the RH alone. This being the case, the RH will be limited to cleaning and/or irrigating or to flushing toilets. Even within these limitations, there may not be sufficient rainwater for these tasks. Using the average daily requirement for toilet flushing: the tank storage = (3000 x 0.35) m3/365days x 18 = 51.79 m3 Using the average daily requirement for cleaning or irrigating: the tank storage = (3000 x (0.12 + 0.06)) m3/365days x 18 = 26.63 m3 Using the aforementioned EA (2003) data, a smaller size is optimal. This being the case, if the RH is used to flush toilets, the respective tank sizes for the hotel and the school are going to be 23 m3 and 14 m3. If the method of estimation used is the supply-side method (i.e. it is based upon capacity, overflow and drainage (see the tdix A)), the the optimal respective tank sizes for the hotel and the school will be 35 m3recomm3 m3 and 35 m3ing for these figures is represented bycalculations ad A-3 (seein Appendix A)The selection ultimately made may depend on a combination of these methods of calculation, as well as the price of the tankAfter this, th 4.2 Grey water recycling at the school and the hotel Metcalf and Eddy (1991) refer to two kinds of wastewater. These are grey and black wastewater. Black water has been flushed down toilets, passed through the drainage system and on to treatment plants. Black water is contaminated with more pollutants than grey water. Grey water accounts for all of the wastewater which has not been used to flush toilets (EA, 2003). It can be treated and then reused for flushing toilets or irrigating soil (Metcalf and Eddy, 1991). Both Waggett (2004) and the EA (2008) refer to grey water from washing machines, kitchen sinks and dishwashers as black wastewater, as it is heavily contaminated and can contain large amounts of grease and food particles. Figures 3.1 and 3.3 illustrate that the two buildings will produce grey water at the levels of 55% at the hotel and 32% at the school, 32% and al.

These factors are referred to as the pillars of sustainable development (Hunt and Rogers, 2005). This part of the report evaluates the potential methods for decreasing the buildings water requirements in terms of their impact upon the aforementioned pillars of sustainable development. The cost effectiveness of the options If less water is required, then less money will be spent on sewage treatment and savings will also be made in terms of spending on water (Otterpohl, 2006). The savings on water will not necessarily be very large, as UK water prices are not high. The savings made by implementing the green technologies would need to be set against the cost of their implementation in order to work out how long it would take for them to financially justify the expenditure. The necessary predictions of expected usage would be difficult to make, particularly for the school building, which would have very low usage during holiday periods. In the case of the school, grey water would probably not be cost effective (as discussed earlier) and would probably need a very long time to make sufficient savings to cover is not co2003) estimate a 30% saving on water expenditure is needed to justify investment in the reuse of grey water and it is unlikely that this would be achieved at the schoolMoreover, at the se kitchen eyecyclis Grey water would, however, be cost effective in hotels; especially big hotels with en-suite accommodation, as customers would consume large quantities of water systems afihite bathrooms and powerful showers an expected part of modern hotels, water consumption is actually higher in the newer establishments, making recycling of non-potable water even more relevantUnlike the majoritutilise treated grey water for toilet flushing when it is busy and revert to its main supply when there are few customer, in order to avoid keeping the grey water in their tank for extended periods. This is common practice in countries with low rainfallrefore, greywatergrey water is The extra setup required to circulate the treated grey water around the hotel would need significant expenditure from those funding the project and this would have to be given serious thought before deciding whether it would pay off in the long term. Rain harvesting setups are fairly commonplace at UK schools, as the water is considered to be fairly clean and the running costs are not too. With a lot of water used for toilet flushing, there would be a need for a big tank at the school, which could lead to a big saving over. To carry out a similar harvesting operation, the hotel would require both a large harvesting area (on the roof) and sufficient room to keep the tank. This would probably not be workable for most hotels. Establishments with swimming pools might consider harvesting and treating water to use in their pool. Social costs The costs to society of these solutions would take the form of problems with their acceptability and/or their reliability (Hunt et al., 2006) (see Appendix C). Environmental costs Braithwaite (2006) views sustainability and environmental protection as being more or less the same thing, with an emphasis upon ensuring that the construction and the running of the buildings is not damaging to the local area going forward. To ensure this does not happen, evaluation of the likely negative externalities of the technologies put forward is needed. Water sustainability for the project might be measured in terms of factors such as impact on the climate, biological diversity and resource depletion. While all of these factors have an environmental aspect to them, climate effects can also create problems in economic terms as well as problems for society in general (Hunt et al., 2006). The recommended technologies need to be beneficial in terms of future sustainability, with emphasis placed on decreasing both the quantity of water that is wasted and the quantity that is obtained from the mains source. Integrated costs On most projects, planners would tend to opt for familiar solutions that are known to be effective over new ones which they might perceive as inherently risky and this might be a factor in the selection made here, particularly in the case of the school, given consideration of the involvement of children (Hunt et al., 2006).

Phantom Limbs, Phantom Pain, And The Essay -- Biology Essays Research

Phantom Limbs, Phantom Pain, And The "I-Function" The so-called "I-function" which describes the brain's sense of self takes on interesting connotations when discussing phantom limbs and associated phantom pain. The loss of an arm or leg through amputation is not an easy experience to endure, and is even more difficult when the patient begins to feel sensations in their now missing limb. These feelings, sometimes referred to as "stump hallucination", is the subjective sensation, not arising from an external stimulus, that an amputated limb is still present (1). Although they no longer exist, patients perceive these limbs as still being essential components of their body-image, and continues to move in sync with their torso and other limbs. For some amputees, these phantom sensations may be no more than painless distractions of pressure, warmth, and cold that do not interfere with their everyday lives. But for the majority of amputees, about 50% to 80% (2), they experience phantom pains that vary in classification from cramping, burning, tingling, shocking, shooting and stabbing pains. These episodes are severe enough to interfere with work, sleep and normal function and do require some kind of treatment. Phantom pain can occur anytime, from immediately after an amputation to several years later. The powerful impression of a stable, embodied self is taken for granted. But it's an perception that's possible only because of the body image created by the brain. A significant element of that image is a mental map of the body surface, generated by the cortex using the sensory signals it receives from the skin. Other regions of the cortex control other components, such as the position of muscles and joints (proprioception),... ... http://www.bfe.org/protocol/pro05eng.htm 3)THEY DO IT WITH MIRRORS , From New Scientist http://infotrac.galegroup.com/itweb/brynmawr_main?http_rc=400&class=session&sev=temp&type=session&cause=http%3A%2F%2Fweb1.infotrac.galegroup.com%2Fitw%2Finfomark%2F805%2F448%2F25790840w3%2Fpurl%3Drc1_EAIM_0_A63676311%26dyn%3D4!ar_fmt%3Fsw_aep%3Dbrynmawr_main&cont=&msg=No+Session+cookies&sserv=no 4) Harris, J.

Costco History

The History of Costco Wholesale DeAna Castro Wilmington University MGT 6501 Abstract Costco is a members only, international retail chain discount warehouse Club. They combine high quality merchandise with low prices. Costco began in 1976 as Price Club and restructured in 1997 as Costco Wholesales. Costco’s passion, mission, and ethics have been the key to the leading membership warehouse retail giant to supply their customers with low prices. Their low cost business strategies and dedication to their employees, suppliers and shareholders have proven success. The History of CostcoThe history of Costco began in July, 1976, in San Diego, California, and its name was Price Club. It was cofounded by Sol and Robert Price. The newly designed business was the first ‘warehouse’ business of it’s kind. This retail business originally targeted other business owners, but blended retail and wholesale. Price Club had unbeatable low prices and sold bulk items. Three years later, 1979, Price Club expanded two new locations. They acquired 200,000 members and profited 1 million dollars. Price Cub showed a loss of profits the first year, but the expansion proved profitable.Jim Sinegal is a key player to the success of Costco because he started his career being mentored by Sol Price. He worked in the warehouse business at Price Club and another warehouse business called Fedmart, both owned by Sol Price. (Cardon). In 1983, Jim Sinegal and Jeff Brottman would open their own warehouse club near Seattle Washington, and it was called Costco (Daft, 2012 pp. 605). One year later, Costco expanded to nine warehouses in five states. It was not long before Price Club realized they could achieve larger cliental if they served a selected audience of ‘non-business’ members.This payed off by the year 1984, Price Club sales would be greater than one billion dollars and is the first company to achieve this mark in a six year period. Almost ten years later, 1 993, Costco and Price Club, would merge and become PriceCostco. This merge was nicely matched because they were very similar in business model and size. The combined companies included 206 locations and generated $16 billion in annual sales. Jim Sinegal would also become Costco’s President and chief executive (Priceviewer). The merger only lasted about four years and, in 1997, PriceCostco became Costco.Jim Sinegal remained President and chief executer (Carden, 2011). Costco’s Mission statement: To continually provide our members with quality goods and services at the lowest possible prices in order to achieve our mission we will conduct our business with the following Code of Ethics in mind: Obey the law, Take care of our members and our employees, and respect our vendors/suppliers. â€Å"If we do these four things throughout our organization, then we will realize our ultimate goal, which is to reward our shareholders. † Jim Sinegal. (Costco, 2011)Costco’ s operating philosophy is to keep costs down, and pass the savings on to their customers. To offer high quality brand name merchandise at prices below any other avenue of retail. They accomplish this several ways. They buy high volumes of merchandise directly from manufactures and not distributers. The merchandise is shipped directly to a selling warehouse and not a storage area, and this also reduces freight costs. Costco warehouses are located on sites where property costs are minimum not on high real estate locations. Merchandise, or stock, is placed directly on a selling floor and on the pallets that they are delivered on.By doing this, labor and handling, costs are reduced to save the customer money. Sales and service employees are kept at a minimal to also reduce overhead costs. Last, because Costco’s has such an incredibly large membership base they have influence and power to haggle prices with their manufacturers and suppliers. â€Å"Costco is able to offer lower pr ices and better values by eliminating virtually all the frills and costs historically associated with conventional wholesalers and retailers, including salespeople, fancy buildings, delivery, billing and accounts receivable.We run a tight operation with extremely low overhead which enables us to pass on dramatic savings to our members. † Jim Sinegal (corporate, 2012). Costco pride’s themselves as a leading warehouse/big box retailer. Sales volume exceeds that of their competition and they use a â€Å"consumer first† business model. This business model is a creative way that has expanded sales. Costco has developed additional ways to continue to save money for their customers. They did this by creating their own brand. Costco’s personal brand is ‘Kirkland Signature. Kirkland, Washington's the root of Costco and is where their headquarters is located. Kirkland Signature brand was introduced to Costco stores in 1995. It was designed to be equal or bette r quality than national brands. Kirkland Signature products include diapers, coffee, tires, clothing, film, housewares and more. (Priceviewer). Often, national brands are co- brands with Kirkland Signature products. Some manufactures realize the success and power of Costco and have agreed to manufacture products with the Kirkland Signature label. Some companies include Hanes and Whirlpool. Branch, 1999). â€Å"Costco continues to prove their â€Å"consumer first† business model, through the creation of new and unique business concepts, included Costco Pharmacy (1986) Produce and Bakery (1987), Optical labs (1987), 1-Hour Photo (1989), Hearing Aid Centers (1994), Costco Gas stations (1995), Costco business Centers (1996), Costco Travel (2000), Costco Home (2003), and Car Washes (2006)† (Walker, 2011). Costco’s structure and culture, meets customer needs further than low prices. Costco focuses on value of it’s products but also focuses on value of itâ€℠¢s employees.They believe that achieving a long term objectives of reducing employee turnover and enhancing employee satisfaction is beneficial. To accomplish this they hire employees at an above average hourly rate, they train and promote from within. Doing this, their employees feel loyalty and valued. Costco Continues to be financially successful today and has expanded internationally. Their mission and ethics have proved to be successful and beneficial to all that the organization is involved with to include, customers employees, suppliers/vendors and stockholders.What does organizational design truly mean? Have you considered how it can work best? If yes, how? If no, why not? Organizational design is a formal process for integrating people, information, and technology. Organizations are people that have a declaration of purpose, vision and strategy. This structure matches people to the purpose it seeks to achieve a common goal or purpose. It is designed to enhance communication , information, and resources to optimize human achievement. The end product is an integrated system of people and resources tailored to the specific direction of the organization.Organizational design basically is an execution of an administrative plan guided by a leader/leaders. The design of the organization can work best if the people work together as a team. It will also work best, if the mission, vision, strategy, purpose and needs of the organization are identified and the goals are achievable. Organizations also work best if it’s leader understands, guides and assures the process is followed and encourages creative thinking. If their is not an effective leader who does not have a mission, vision, strategy and followers, the organization can and will fail.Costco has proven to have a successful organizational design. Describe the â€Å"Trap of favored ways of thinking†? How did it impact your thinking? In Organizations ‘traps’ can be hazardous to thei r success. These traps can prohibit and restrict creativity, limits capabilities and limits ability to progress into the future. Some common traps are: Group Thinking- Productive conflict is critical if common traits are shared in a group because it prevents bad ideas from being implemented without discussion or consideration. Non productive conflict is not productive and can become a hostile situation.Group thinking is pervasive. â€Å"We have never done it like this before† If you always do what you do, you always get what you got. Be courages and attempt change. Make sure to make meaning changes. â€Å"You’re Gooder† syndrome- Respect is over emphasized to their authorities and lacks candor, honesty and courage. Inbred Culture When hiring employees is based on time, ore years of service and loyalty rather than exceptional performance. Problems will arise. The leadership chain of command will be incompetent and will breed more incompetence. Arbitrary Directive s and policies are determined by top management.If decisions and policies are made with randomness and for unknown reason then those are signs that indicates that the leader is disconnected and out of touch. This truly impacted my thinking because I was not aware and I learned many things! It made so much since why organizations struggle, fail and succeed. It caused many flashbacks to my military career, and also, my teachers, mentors and friends. When I think about this, in reference to Costco, any of these trapped ways of thinking could have jeopardized their success. â€Å"The Ugly Face† often stifles an organizations growth. How? Did you position to circumvent it in your design?The ugly face refers to organizations that exploit employees, the global economy, or the natural environment as instruments of domination that furthers selfish needs and dominance. Taking what they need and throwing or destroying what isn’t needed. â€Å"Whether by design or default, organi zations often have a large negative impact on our world. † (Morgan,1998 pp. 261). Pollutants, poisons and other cancer causing hazards are ingested or promoted by food and tobacco companies. Similar threats are caused from environmental pollutions that are legally and illegally dumped in water and land.Contaminated air, land and water hurt people causing cancer or other health problems and big corporations that cause these hazards are sometimes not penalized. These organizations place profits before human welfare. Foreign countries are easily manipulated by employment with hazards, disease, and degradation. Costco has circumvented many of the â€Å"ugly face† views by taking care or rewarding their customers, employees, and suppliers. They take care of their employees by giving them a substantially higher pay than other companies, they promote from within and they are rewarded and valued as people.Globally, Costco has expanded to foreign countries and has provided emplo yment and opportunities for others by creating employment, giving them higher above average salaries and valuing them as people with respect and appreciation.

Chromatography Definition and Examples Chromatography is a group of laboratory techniques to separate the components of a mixture by passing the mixture through a stationary phase. Typically, the sample is suspended in the liquid or gas phase and is separated or identified based on how it flows through or around a liquid or solid phase. Types of Chromatography The two broad categories of chromatography are liquid chromatography (LC) and gas chromatography (GC). Highs of other types of chromatography include ion exchange chromatography, resin chromatography, and paper chromatography. Uses of Chromatography Chromatography is used primarily to separate components of a mixture so that they can be identified or collected. It can be a useful diagnostic technique or part of a purification scheme.

Analysis of the use of music in advertising.

Analysis of the use of music in advertising. IntroductionEmotional PlaygroundMusic has been known for centuries to have a powerful effect on human responses. In the social science context, music is particularly known for its effectiveness in triggering moods and communicating nonverbally. Many marketing practitioners already accept this notion, given that music is increasingly used as a stimulus in the retail environment as well as in radio and television advertising. Music has been shown to affect consumer behaviours, particularly shopper behaviour (Milliman, 1986), as well as emotional responses (Kellaris and Kent, 1994). Marketers that playing music is in itself not enough, that music needs to be used to target groups in the market place, to differentiate from competitors and to maximise image rather than serving as a distraction. It is therefore not surprising that music has become a major component of consumer marketing, both at the point of purchase and in advertising (Bruner 1990). In this essay we will explore the role of music in advertising.AdvertisingSeidman (1981) reviewed the contributions of music to media productions (movies and educational films), concluding that cognitive and affective comprehension of stimuli can be influenced. Music is a complex chemistry of controllable elements (Bruner, 1990). Unfortunately, no definitive taxonomy of music elements has been developed. Time and pitch-related characteristics appear on almost all lists and also have some empirical confirmation (Kellaris and Kent, 1994). Though less clear, evidence also has been found for a third factor, musical texture (Bruner, 1990).Advertisers often deliberately try to convey and transfer underlying, yet unasserted, meanings to viewers. The view that an advertisement is a one-way communicative process is a narrow one since one also needs to consider the information processing responses of the receivers as they perceive and interpret messages and images in advertisements (Procter et al 2001). Designers of advertising me ssages expect viewers...

The paper focuses on identifying theory and concepts, which exists in the field of Lean and Six Sigma management within the healthcare industry. This chapter also focuses on identifying the origin, the tools and techniques, and the current level of Six Sigma implementation within NHS hospitals and healthcare industry at large. The information gathered from the literature review will contribute significantly towards making of effective conclusions on Lean and Six Sigma management in NHS Hospitals. The healthcare industry is a vast web of contradiction and complexity. It has focused on the provision of astounding advances in treatment and technology. However, this industry is a victim of resource constraints, errors, inefficiencies and several other issues, which are a threat to safety and accessibility of patient care safety. The Institute of Medicine, in 2008, released a report, which indicated that over 98,000 people die annually due to medical errors. This report highlighted a need for effective, quality improvement within the healthcare industry. Financial concern has become a factor, which influence the efficiency of operation of healthcare institutions. This is because the cost of supplies and labour has constantly increased in healthcare organisations while the reimbursements have declined effectively. Therefore, two areas are necessary in order to increase savings for healthcare organisations. These areas are reduction of supplies and labour costs. On the other hand, healthcare organisations are facing a shortage of qualified professionals, registered radiologic technologists, and registered nurses.
