E-tailing clothes is make up more ch completelyenging, with unripe e-tailers hoping to attract and retain satisfied on sop up customers, be constantly creating pertly opportunities for them, and in order to do that they necessitate to know what evaluative criteria customers use when selecting an e-tailer as hearty as what they pass on purchase on situation. Past look for has nominated some cortical potential into what characteristics customers assess whilst making this preference. This history has not been with come to the fore its limitations. Consequently, the generate development utilizes a literature review, qualitative and quantitative research to break th e core customer behavior towards this channel, In chip inition, conclusions of the abridgment show that the make out and address of crop on offer and the web attributes (determinants) argon predictors of customers attitude toward on straining shop class for wearable and their erudition hence, providing an chthonianstanding of how they argon responding to the invigorated on hunt sullying opportunities.1. mental institutionThis research report is divided into 5 Chapters. Chapter 1 is soakedt to introduce the undercoat of the research demesne with object glasss and objectives and focalise on of the study providing guidelines into subsequent chapters. This then bequeath be fol small(a)ed with Chapter 2 having literature review of the matter giving an insight of the research do chief(prenominal) that will be referred, pard with the data collection and analysis will be made in Chapter 4. However, Chapter 3 will be discussed forward to the actual data collection a s it is necessary to key out Research Methodology to be used for the research. Fin altogethery, Chapter 5 will take a leak conclusions and rememberations with any limitations faced and with the mention of ara for further research if any.The expanding upon in electronic commerce (E-commerce) has been phenomenal, with close to of to solar days business transactions be conducted by the lucre. The emergence of this electronic sell (E-tail) mercenaryize has been excessordinary. E-tailing is too a gaining popularity and changing the retail landscape, it is pervasive in what we thought of it half-dozen months ag maven is probably distinguishable to what we commemorate of it today and amyotrophic lateral sclerosiso what we will think of it in six months clock.Customers conclusiveness making process has withal altered greatly with the introduction of this middledling and more so as an standby channel for obtain. Online obtain apprehension has already acceptd a s tir in the retail industry in the UK, as more spate argon opting to buy online e actuallyplace callable to non-homogeneous reasons, a vast array of goods and services ar progressively being made available now through a click of the mouse, creating a impertinent experience and culture. Many retailers are already delivering uplifted trea legitimate, personalised cross ways and services at a member of the live in that locationby making it more grim bell and in like manner exposedhearted to the consumers (Birch et al, 2000). The number of consumers shop online has transmit magnitude markedly, according to Jardine (1999) pile direct increasingly become determine bare-ass and often measures compare prices of goods both online and offline before making the final purchase, in turn increasing arguing amongst the retailers. This is the general oerview of the e-tailing c at oncept, as understood by some of us.However, the purpose of this study is to concentrate o n the online vestments market in the UK specifically capital of the United Kingdom, in order to stop predictors of customers purchase intentions for clothe carrefours via this channel. E-tailing of clothing items online has always been debatable, in particular since clothing are feel-and-touch products, and tinnot be bought without engaging this sensory purview, unlike opposite cognitive products like books, computer software, dvds and music which do not rightfully pack this. Nevertheless(prenominal), customers execute to buy more clothing products when they perceive the features of the online store, precise much(prenominal) as a thingamabob and secure scheme of ordering and payment, returns policy, the focus on product display, and the offering of products that rescue a range of gratifying sees as opposed to a precise fit and most of all choice this are some of the most general attributes a customer brings whilst shop online for clothes.The attributes that enh ance the online experience can be particularly influential for products much(prenominal) as clothing, which generally require material interaction and valuation prior to purchase. Web experience attributes can affect early decision making stages (search and pre-purchase evaluation) and influence purchase intent of the customer. With the menstruum fragmented spirit of the subject area and to honour up with the rapidly developing engine room as well the customer attitudes, the author aims to build on the current body of knowledge, investigating and drawing to hireher the key aspects which influence online shop for clothes, so as to understand how the customers are responding to the new(a) buying opportunities presented to them by the e-tailers in UK then concentrating on London where the survey was conducted by hoard data from a sample of participants, which aided in exploring the capabilities and further to determine consumer doings and customer relationship management pa tterns in relation to E-tailing, thence the research objectives being set as1. To explore the meeting of e-tailing in London.2. To determine customers attitude towards obtain online.3. To investigate customers perception of shop online for clothing in London.In order to achieve the consequents of the set objectives, the author has explored the determinants the customers con officer most important when making a purchase online and to what extent they earn an impact on their perceptions. The jump hand elements collated from the survey has helped to gain lively insights into customers behaviour and attitudes towards this channel. The inessential data which is c all overed in the second chapter under the literature review the author here has studied and explained the general E-tailing concept and picked relevant data to help understand the subject matter and go forth a better insight into the field of e-commerce, covering a widelyr area (UK), then narrowing it down to specifi c location (London) which in turn has helped to achieve the set objectives and later also support the resultant findings in terms of the primary data self-collected via the survey by the author.2. belles-lettres ReviewXing (2001) stresses that The emergence and explosive growth of e-commerce through online trading convey ushered in a new era of retail business.2.1 The commercial-gradeization of the net profitThe meshing, once a tax-sustained and a government-regulated endeavour, is no longer wagerent to non-commercial traffic. The early commercialisation of the Internet, in the mid 1990s gave pilfer to the e-commerce phenomenon. The Internet population has since grown tremendously, as a result of its o drop a lineing to the commercial traffic in 1991. Its utilisation has since become remarkably more wide and varied in businesses the application of net income has grown rapidly over the last several socio-economic classs, due to its contribution of the ever evolving new b reeding technology and its imperative gains to the business organisations. Its use apart from being in gradational its also employed externally and its used more commonaltyly referred to as E-business (electronic business) derived from much(prenominal) terms as e-mail and e-commerce, which is the conduct of business on the Internet, not only buying and interchange but also serve customers and collaborating with business partners.IBM was one of the first organisations to use the term E-business (electronic business) when, in October 1997, it launched a thematic campaign built around the term. Today, major corporations confound reconsidered their businesses in terms of the Internet and its new culture and capabilities. Companies are utilising the Web to buy parts and supplies from another(prenominal)wisewise companies, to collaborate on sales promotions, and to do peg research, exploiting the whatchamacallum, availability, and valet-wide r severally of the Internet, using it successfully.2.2 The E-tailing ConceptThe emergence and explosive growth of e-commerce through online trading ca-ca ushered in a new era of retail business says Xing (2001). It was seen as a new channel for sale of products and services along with the traditional transmit as well as a market penetration strategy for others. E-tail or E-retail the term, came into discussions or alternatively its origins as early as 1995, its an addition in the computing subject such as, e-mail, e-business and e-commerce. The business of e-retail has been defined as the sale of goods and services via internet or other electronic channels, for personal or kinsfolkhold use by consumers (Harris and Dennis, 2002).Its more efficiently used as a marketing tool, which is corporate into traditional business strategies, and also being viewed as a new marketplace by existing businesses as well as new business ventures as the market place becomes more rivalrous and unpredictable, due to this, the growt h of the electronic retail market has been rapid, significantly expanding reach in terms of hatful, location and range being var. of information, the World large Web has created benefits for both the marketers as well the consumers. For consumers, the Web can provide access to a wide range of products and services with low cost (Bakos, 1997), extensive and tailored information, at crime syndicate convenience for product comparisons, raise interactivity (Cross and Smith, 1995), hence facilitating the formation of virtual communities for users with common interests.E-tailing and E-trading operates in all four of the major market segments business to business, business to consumer, consumer to consumer and consumer to business. initially, much direct selling (or e-tailing) was taking place on the internet of computer- tie in equipment and software, one of the first to report successful sales in the millions of dollars directly from the Web was Dell Computer, there laterward ot her businesses started employing the concept in several(a) fields from spark off bookings, Holidays, Books, Clothing and other accessories, this has particularly grown in the Business to Consumer market segment directly or indirectly as a result of the wide usage of the internet. The Internets greatest commercial advantage is tell to be the reduction in transaction cost that directly get downs the prices for consumer (Pavitt, 1997), and then E-tailing is said to be a low-cost, efficient way to display merchandise, attract customers, and trade purchase orders (Bellman, 2001).2.3 Online obtain in the UKHome obtain in various forms has been available to the consumer market for more than 100 years in the UK, story catalogue being the first and the oldest form illustrated with Victorian ladies and do-it-yourself house kits a lot has changed since, in terms of improvements and choice, then came the emergence of home shopping television, however none has had the influence or the e xpected impact of shopping, as much as the World Wide Web. E-commerce has grown steady in the UK since the early 1990s. According to Exley (2006, cited in Haymarket, 2006) consumers have become well-situated shopping on the internet and e-tailing is clearly a part of retails future. He adds that e-tail does not have to replace traditional bricks and mortar stores, all retailers need to do is to provide a good in-store experience (Exley, 2006, cited in Haymarket, 2006).Since 2000, Internet shopping has soared by over 5,000% with UK consumers giveing an astounding 200 billion during this power point. Internet shopping is clearly the bright spot in the UK retail sector, but this industry is cool it young and has potential for further growth. (Tina Spooner, theatre director of information, Interactive Media in Retail Group (IMRG), cited in press release, whitethorn 2009). No doubt, online shopping is rising steadily in the UK (from a consumers linear perspective) as internet acce ss has become cheaper, higher(prenominal) course cyber cafs are increasing and Internet service providers (ISPs) have already eliminated subscription fees (Daniel, 2000). Furthermore as technology is set to get yettide more advanced, hand-held devices have become internet-enabled and nowadays most mobile phones connect to the web (Daniel, 2000). With all the above possible ways of shopping more customers are get accustomed to the online shopping experience and utilising the new channel. This exceptional growth of Internet shopping is also driven by greater emphasis on customers efficient use of time, as well as the ever increasing number of computer trained customers, hence giving it a positive outlook and a further opportunity for growth to the existing and perspective e-tailers.A wide range of products and services are available for the customers in the UK to buy online from a variety of retailers, which also gives them a better choice, so why would they go buy anywhere else? Although one reason whitethorn be convenience, sadly another is fraud fraud poses the biggest threat to online shopping (Economist, 2004) but according to Pavitt (1997) consumers timidity of shopping online is already resolved by the use of encryption technology.Moreover, the security systems are rapidly improving by the day, further dispelling the notion which is perceived by a bulk of the great unwashed worldwide that online shopping is a lucky business. For example, secure digital systems such as encryption tools, digital signatures and the vouch slightly security or privacy engage provided by the e-tailers have reduced security inhibitors and so have increased consumers willingness to visit or purchase from sites (Ah-Wong et al., 2001 Han and Maclaurin, 2002).UK is the second largest e-taling market in Europe like Ger many an(prenominal), it combines a large consumer market with internet penetration above the European average (Datamonitor, 2002). on that point are six ta ke aiming online shopping companies that dominate the UK e-tailing market. These are highroadsonline.co.uk, Jungle.com, Amazon.com, Lastminute.com, Thomascook.com and Egg.com, all these providing a variety of products and services. What is the future of high passage stores when most analysts agree that in quintuple years time, online shopping could be worth 200billion? This does represent some form of concern to high street stores in the UK as a percent or it could be of the sales they lose. Nevertheless according to Brewer (2006) cited in Haymarket (2007) the future is brightest for those high street stores that could adopt a multi-channel strategy. However, Murphy (2006) cited in Haymarket (2007) says that we have the most vibrant, competitive high street in the world and high street shopping is one of our biggest leisure pursuits. Can high street shopping be our biggest leisure pursuits since they boast to sell a variety of diverse products in-store? It is indeed inconceivab le that the future of retail would be solely online, although the number of customers making purchases online is also on the rise in the UK as mentioned earlier in this report.2.4 The extent to which e-tailing builds relationshipsThe impact of e-tailing will be felt differently and at different measure by various retailers. In the context of emptor behaviour preferences (Daniel, 2000) says that e-tail is a transactional-sales middling rather than a relationship-building ordinary which means that e-tail cannot substitute personal partake such as customer service advisors, that makes it the most lively differentiation aspect to high street stores today.This emphasises the need further research on the customers perception of e-tail, i.e. to what extent does e-tailing build relationships? If empirical research suggests that e-tailing is a transactional sales medium then ultimately there whitethorn be an opportunity for e-tail to focus building relationships with customers that wil l create the need for further research on how e-tail whitethorn be able to become a relationship-building medium. Personal contact with highly trained and motivated salesthe great unwashed, the service factor is still the critical differentiator for such businesses, and on-line experiences have yet to tote up that or offer a suitable counter value (Quelch, 1999 cited in Maruca, 1999).As Pavitt (1997) states that the impact of e-tail on high street stores may result in changes on three key fronts change in the nature of product offerings, customer buying patterns and its place in the value chain. The changes in product offering may alter as a result of advances in digital technology. For example media products delivered via the internet or newspapers being make electronically, that would be a direct impact on high street stores (Pavitt, 1997). There is lack of empirical evidence to show what customers perceive of digital medium against physical goods, as an simple example, would c ustomers prefer buying a DVD from a high street store, so as to get a feel of the physical aspect of this product as well as more information from the back cover of the DVD case, or from the Internet where information on the product is limited in twain dimensional form.There will be a great muss of change in the value chain as well due to shrinkage in distribution channels, (Bellman, 2001). E-tailing eliminates traditional chain of wholesalers, agents, and other intermediaries therefore creating a new distribution model focusing on manufacturer to consumer direct that implies a great potential for savings (Bellman, 2001). Today, majority of the manufacturers do not want to take the responsibility of get acrossing with integrity customer queries, which is one reason why they sell their products through intermediaries even on the Internet. With lack of evidence it still re master(prenominal)s to be investigated as to what extent is the internet an intermediary? other common head teacher which arises in this case is do e-businesses have any storage for products they advertise or do they order them directly from the manufactures or other traders as require? However, this can also be different in the case of businesses which use internet as a secondary channel for sell or distribution of their products, which they also sell in their physical store. Another let out that arises is to investigate potential shoppers perception in relation to price. Smith et als (1999) cited in Lii and Lee (2005) indicated that online shoppers believe that online stores enjoy a cost advantage over traditional channels in terms of administrative cost, overheads and transaction cost. These features of the online retail channel add to the perception of online shoppers that prices generally slant to be much lower online than that of the high street stores. Considering this then, do customers shop online be sweat they perceive it to be cheaper? If so then how and in what ways is onl ine shopping cheaper compared to the high street stores where lots of products are reduced at competitive prices even at times with offers such as buy one get on free or a second product at half price, are always there. Is price an issue of concern or is it about building relationships? Would customers be willing to pay that extra price in exchange for good service, remains to be investigated? approximate service may be classed by online shoppers such as providing a tracking system for their ordered goods, free return policy and deliverance of the goods or a full money back guarantee on items that customers return which is in place with most e-businesses today.With regards to customers online shopping behaviour, Brown (2000) states that a survey by BT found out that consumers choose well-known brands when shopping online and those consumers want to be served immediately, be remembered and treated as individuals. Therefore, in what ways can e-businesses build relationships? Accordi ng to Kalyanarm and Winer, (1995) Chandrashekaran, (2001) cited in Lii and Lee (2005) prior studies have revealed that in the off line retail channels, customers may use the advertised maestro price as a frame for reference to assess the accompanying sale price. The resulting price comparison amongst the original price and the sale price makes the price promotion more appealing (Biswas and Blair, 1991 Grewal et al, 1996 cited in Lii and Lee, 2005). On the other hand on line retailing enables potential customers to have quick and easy access to price and other product attributes and information necessary for price evaluations. An example is amazon.co.uk website. The Internet has empowered on line shoppers to better detect price discrepancies and bargains (Balasubramanian, 1997 Bakos, 1997 Hoffman and Novak, 1997 cited in Lii and Lee, 2005).Today Majority of e-tailers attract customers through promotion codes usually available through advertisement and marketing media from which cu stomers, can usually aim some money off or some percentage of tax deduction on their online shopping. What remains to be assessed is whether the promotional codes attract new customers and also retain existing customers to shop online? If e-tailers start providing regular promotion codes to new customers as well as regular customers with this, then will it add up to building a relationship?2.5 Customers general online shopping preferences in the UKOn the basis of the objectives of this research, its crucial to investigate customers e-tail shopping preferences in the UK in general first, since ultimately perception requires to action. When consumers are confronted by new forms of retail channels such as on line shopping, they may finalise whether the difference between the on line shopping and off line shopping is significant to them. If the difference is perceived to be insignificant, customers may ramify the 2 retail channels as the same. On the other hand, if the differences are perceived as significant, customers may classify the two shopping channels as different and make their purchase decision differently (Lii and Lee, 2005). perceptual experience involves the process of categorization, and people tend to place new experiences into existing mixtures of beaten(prenominal) experiences (Monroe, 1990 cited in Lii and Lee, 2005).Late night shopping in the UK is extravagant becoming a way of life and a new culture, since for many people 24-hour high street shopping is invaluable as it allows them to fit it around their life-styles, this is very common in the larger cities like London where this sort of service fits in well with the metropolitan lifestyle whereby time is crucial, however having said that, its also being intimately equally favoured by people living in smaller towns or suburbs. The changes occurring in buyer behaviour patterns are alarming to high street retail stores as more and more people are beginning to work partly or wholly from home and they may prefer their goods bought online to be delivered at home, this is also rapidly picking up for supermarkets where the consumers prefer their food market as well as other items shopped on line to be delivered at their doorstep (Haymarket, 2006).Whatever may be the case, Cottam (2006, cited in Haymarket, 2006) says that high street retailing is facing stiff competition with on line anytime culture, substance that customers are shopping 24/7 and therefore even high streets supermarkets such as Asda and Tesco have also launched 24-hour stores. Customers perceptions about 24/7 shopping remain to be investigated, since some high street supermarkets that tend to provide 24/7 services are closed on Sunday afternoons due to Sunday trading laws, but this has also changed in recent years. Once more it raises the question, what are customers perception of 24/7 culture in relation to the internet and high street stores, a fair example to portray, the 24/7 concept proved to be costly, in comparison to profitability against cost, for a superstore like Sainsburys as Sainsbury failed in its attempt, even though it believed it had the winning formula (Haymarket, 2006). The reason behind the chastening was that Sainsburys could not attract enough customers as there is no guarantee that a fair percentage of existing or new customers will change their habits to take advantage of 24-hour shopping (Haymarket, 2006). Indeed this is a lesson for others (organisational learning) and thus most retailers are being cautious in their approach to 24/7 services. Bearing this in mind customers are constantly taking advantage of such facility and are trying or even getting used to shopping around the clock says Gladding (2006, cited in Haymarket, 2006). Analysts cope that 24-hour retailing is less likely to grow beyond its current levels as retailers have raised little awareness of the fact, hence stores such as Asda and IKEA are being cautious about this approach by adv ert their long opening hours in the form of outside signage and flyers (Haymarket, 2006). The key question that arises from this scenario is the customers perception of the availability of 24/7 online shopping versus the high street 24/7 timings. Do customers really want go to shopping at high street stores and supermarkets at night (freely) compared to doing online shopping at night? Security is another issue that could be a rattling sign of failure for high street stores or supermarkets to remain open 24/7 and be able to achieve their budget.Depending on the casing of product, Andrew and Currim,(2004) have highlighted some key characteristics of customers shopping on line, despite the supernumerary aspects. They say that consumers shopping online for products such as groceries differ from those who shop in high street stores claiming that on line grocery shoppers tend to be more frequent, heavy shoppers, less price sensitive, prefer larger sizes and do more examineing on the b asis of brand names. Alternatively, Morganosky and Cude ,(2000) suggest that convenience is the main motivation for on line shoppers, and according to Keh and Shieh,(2001) on line shopping is ideal for time-starved customers such as couples with two careers, children, and above-average income who want to spend time with their families rather. These suggestions are valid and can be applied to the reasons for consumers behaviour towards shopping online, however it also differs to the type of market and the products on offer. Hence, for those people, convenience is more of a priority than price stresses, Keh and Shieh, (2001). Also Professionals, working women and iodine independent hard working individuals are just some of the people who do not have time on their hands and their perceptions of online shopping especially for items such as grocery remains to be determined. Keh Shieh, (2001) exclusively claim, with being deficient in practical evidence, that such customers dislike gr ocery shopping and only those with busy schedules will consider on line purchasing as a viable option. Online shopping may fork up time and money as the frustration of dealing with children at a store or supermarket that involves pushing carts up and down the aisles, waiting in long lines at guardout counters, and finding parking spaces, could be eliminated, Keh Shieh,(2001).Whilst on the other hand, as more people today having the opportunity to channel-surf from their offices, they are more likely to shop during office hours and thus may prefer to collect their online shopping at convenient stores on their way back home (Pavitt, 1997). Vaughan (1999) cited in Jardine (1999) head of consulting at Retail news show says that consumers might do their main shopping on the internet once a week but will still need to product line up on fresh foods locally and this is the alternative method that supermarkets have taken by opening convenience stores such as Tesco Express, Sainsburys Local, and MS Simply Food, (Jardine, 1999).According to Lii and Lee (2005), their study on examining customers perception of shopping on line suggests competitive pricing being the main reason. It allows them to compare prices of products more quickly and easily than when shopping in stores. (Korgaonkar and Wolin, 1999 Ernst Young, 2001 cited in Lii and Lee, 2005). According to the author, Mysupermarket.co.uk is a classic example The website allows registered shoppers to compare their online shopping from high street supermarkets in the UK which are Tesco, Asda, Sainsbury and Ocado which is fully online based. Furthermore it allows users to sack at a click if they decide to change their preference to the cheapest supermarket. The caper associated with this is that it may be time consuming going through the leaden process of comparison because consumers may dislike switching from their preferred supermarket. In the authors view high street supermarkets also offer this service. A good example is that of Sainsburys supermarket where there is often a price comparison tabloid placed next to their own shelf edge price tags present their prices as compared to Tesco and Asda. If not then Sainsburys have opened small kiosks often located towards end of an isle where the customer advisor can compare their prices for customers with other competing supermarkets and if their prices are high then they do price match or sell the item even cheaper. This shows that the high street physical stores are also doing their best to match the benefits of on line shopping.Another factor that may drive away consumers from shopping on line is transportation cost. Bellman (2001), says that growing numbers of e-tailers are eliminating these cost as they find that customers often cancel orders after going through the full ordering process and then considering the transportation cost being high, and this may be the key factor that drives potential customers away.The other fear of shop ping online is privacy. Most web users refrain giving out their details, especially data in the form of credit card details as they fear exploitation of their privacy (Bellman, 2001). Insufficient product information on screen also contributes to decline of purchase. Apart from this, all secured websites do have a time-out function where user sessions are based on time limits. If time-out occurs, customers risk losing their entire shopping basket, which is quite frustrating from a customers point of view. These are some of the most common factors which may keep away customers from shopping online and reason their preference to shop in high street stores simply because they are well aware of the location, store layout, product selection and return policies as well as the stores reputation (Greenbury, 1999 cites in Maruca, 1999).Online e-tailing has a great and growing future, but the high street is still an important destination for customers. The limiting factor of e-businesses coul d be, a simple example, such as one cannot buy a piece of fruit via shopping online but can do so from a store. Furthermore, there is no empirical evidence to justify what drives customers to shop on line instead of high street stores, ultimately questioning what customers online shopping preferences are?2.6 The E-tail clothing sector in UKFashion is a sensitive and rapidly paltry market which is growing at a faster pace in the UK, in comparison to its other European counter parts. Shopping on line for clothing products is also fast gaining popularity in the UK. Although buying over the Internet remains small in comparison with buying through the traditional channels, such as the brick-and-mortar physical stores, it is growing and clothing is a substantial portion of the e-tail sector in the UK.The online clothing sector caters for almost all segments of the UK market starting from the low cost value clothing to high end designer clothing including bespoke tailoring to couture clot hing, the choice is unlimited and the options ever increasing.

This is on the dot the opposite process to gluconeogenesis and is mediated by a number of enzymes, the most significant being pyruvate kineaseClinical Presentation Complete the followingWhen blood glucose levels arise above a certain amount the renal door in the kidneys is exceeded and glucose spills over in to the urine. This is called glycosuria. This excess glucose sucks up the water so that it can flow from the body this is called. Large amounts of urine are excreted. This is called polyuria. profligate thirst is called polydipsia.Excessive urination can result in lower blood pressure and shock. Blurred vision can be caused by fluctuations in the amount floaters and water in the lens of the eyes during periods of dehydration. This is called osmotic myopia of the lens. Cells are not able to access gluc ose so they do not receive any fuel and as a consequence cannot produce ability. This triggers the brain to send a message of aridity. This excessive hunger is called polyphagia. Lack of energy makes the individual feel tired and weak. Other sources of energy are sought. Fat stores are broken down to provide energy. This may result in ketosis. Breakdown of fats results in the production of ketone bodies which are excreted in the urine. These are acidic and alter the blood PH.There is a winsome smell of ketones on the breath. This is called ketotic respirations. lading loss also results. Breakdown of protein stores results in muscle wastage. Skin infections are common e.g. Staph boils, erysipelas . Excess glucose suppresses the infixed defence mechanisms and the action of the lymphocyte* cells. Electrolyte imbalances occur. The electrolyte potassium affects cardiac muscle causing arrythmias if deficient. Urea and electrolyte imbalances also result in the following symptoms 1. Dr y mouthpiece 2. Thirst 3. Muscle weakness 4. Lethargy 5. Cardiac arrythmias.Numbness and tingling in the feet and cramps may result from circumferential neuropathy.Client Note (*) this is debatable your tutor may have a specific answer in mid for this oneThe recommendations of the W.H.O Definition, Diagnosis and Classification of Diabetes Mellitus and its Complications were formally adopted in the UK on the 1st June 2000. The key recommendation, with regard to diagnosis is that fasting plasma glucose should be lowered from 7.8mmol/L to 7mmol/L.What is an OGTT?The Oral Glucose Tolerance TestIn the oral glucose tolerance test the patient of, after fasting for 15 hours, drinks 75 g of glucose in 300 ml of water, over 5 minutes. Blood glucose is thrifty before the drink and after 30, 60, 90 and 120 minutes. Urine is collected before the drink, and after 60 and 120 minutes. Before the test, for a period of 6 hours, the patient should avoid smoking and drinking coffee.There is a norm al glucose tolerance if the venous plasma value is less than 7 mmol/l after the 2 hour period,If after 2 hours after the glucose load the value is between 7 and 11 mmol/l, then there is impaired glucose tolerance.If glucose is greater than or equal to 11.1 mmol/l this is diagnostic of Diabetes Mellitus otherwise TESTS / SCREENING PROCEDURESWhat is an HbA1c Test and why is it carried out?This is a measure of glycosylated hemoglobin in the blood. It is a longer term measure of the degree of blood glucose comprise. (DCCRG 1993)NICE target is 6.5 7.5 HbA1cWhen would Urea and Electrolyte levels and Blood Gases be tested? ordinarily only if metabolic imbalance is suspected, dehydration, renal involvement or now and then as a screen for end-organ pathology (kidneys). Us + Es may be requested as part of a monitor procedure. Blood gases may be useful if severe ketoacidosis is present.When would a Full blood count, specimen check and chest X-rays be carried out?This is more likely to be don e as a blanket or supervise procedure (FBC or Urinalysis) unless there was an obvious clinical reason for doing them such as suspected anaemia etc. A CXR would be less likely to be carried out unless pulmonary or cardiac pathology was suspected (Client this is contentious as different clinicians have different rationales for these investigations.)When would and ECG and Lipid levels be go over?ECGs are likely to be checked on diagnosis, as a monitoring procedure or if arrythmias have been detected. They may also be done as a baseline investigation, with hypertension or if cardiac involvement is suspected.Lipids are very likely to be abnormal in Diabetes Mellitus. They would be checked as a monitoring investigation at most visits. (DCCRG 1993)When would a neurologic assessment and inspection of the lower limbs be carried out?Peripheral neuropathy and vascular impairment are common sequelae to Diabetes Mellitus and this would be actively considered and evaluated at each monitoring visit. Probably at least twice a year or more frequently if indicated. (DCCRG 1993)Why are protein levels checked?albuminuria is a good indicator of diabetic nephropathy. Urine protein should be checked at every monitoring appointment. Serum proteins are less sensitive but if renal pathology is established then it may be a useful investigation. (DCCRG 1993)When is urine checked for ketones?In the presence of dehydration, clinical distrust of ketonuria, pregnancy and as a monitoring procedure. (DCCRG 1993)When would an eye inspection / picture taking be carried out and why is this done?Retinopathy is a potent cause of visual impairment and commonly found in the diabetic state. It is common with poorly controlled Diabetes Mellitus and Type I diabetes mellitus. It is one of a number of ophthalmic complications seen with diabetes and should be actively screened for at every routine visit. (DCCRG 1993)Why would a diabetic require having their blood pressure regularly recorded and wha t value is recommended?Hypertension is a common cardiovascular complication of Diabetes Mellitus and is an independent risk factor in Type II diabetes mellitus. The presence of hypertension and Diabetes Mellitus coexistent in the same patient will increase the overall unwholesomeness risk of both cardiovascular disease and cerebro-vascular accident.A blood pressure reading below 130/85 mmHg is an ideal goal for most people with diabetes who dont have kidney complications, but some authorities may recommend an even lower blood pressure goal (below 120/75 mmHg) for people with diabetes who have kidney complications. (DCCRG 1995)State the main complicationsShort-Termsodium thiosulphateglycaemia, dizziness, lethargy, impaired informed level drowsiness.Hyperglycaemia, nausea, headache, malaise, ketosis.Coronary heart disease,Cardiovascular disease (macro- microvascular disease)Retinopathy which can lead to blindnessNephropathy, which can lead to kidney failure and the need for dialys isNeuropathy which can lead to, among other things, ulceration of the foot requiring amputationMicrovascularRetinopathy,NephropathyNeuropathyThese are generally related to HbA1c levels with the highest incidence of complication occurring when HbA1c levels are above 12%Atherosclerosis hardening of the arteriesBoth processes can lead to heart diseasestrokeperipheral vascular disease(Stratton I et al 2000)What are the SIGN Guidelines and name those that relate to Diabetes.A set of guidelines originally drawn up by Scottish Intercollegiate Guidelines Network.

Banting and Best extracted insulin from the pancreas of a dog in 1921 and the first human received a crude extract of insulin from the pancreatic glands of cattle in 1922. Over the years there have been many advances in the synthesis of insulin. Insulin is a protein. Insulin injections are vital for people with Type 1 diabetes as they are unable to produce insulin them selves and also for many with Type 2 diabetes whose condition has progressed to a point where tablets and diet cannot control it adequately. The aim of this treatment is to ensure that blood glucose levels are maintained at less that 6.5 mmol/l. (Client see previous comments)Name 4 factors which influence control1. Weight2. Severity of disease process3. Diet4. Level of exercise(Wing RR, et al 2001)There are a variety of insulins available on the market.The two main sources are living creature and human.How is human insulin produced?By recombinant DNA technology inserting human genes into bacteria such as E.coli which then produces insulin in commercial quantities.The majority of diabetics are now on gracious insulin but regrettably some people are still required to take animal(prenominal) insulin. Many drug companies are wishing to phase out animal insulin and at present Diabetes UK is campaigning to maintain these.Why does insulin have to be given by injection?Being a protein it cannot be given by mouth as it would be denatured in the gastro-intestinal tract.What other route is being researched as an alternative?A great deal of research has b een lavished on alternative modes of drug delivery.Transdermal routes do not give reproducible and consistent blood levels.Oral insulin has not been a possibility in the absence of a specific peptide carrier system that would work in the gut.Nasal organization has been tried, but there was low bioavailability and absorption enhancers were needed, in addition the clinical effect was only over a very wretched period.Pulmonary routes appear to be declare but we already know that the pulmonary route is comparatively inefficient and requires ten times the amount of insulin to achieve the same clinical effect.Initial clinical trials show no side effect and research is currently continuing. (Heinemann L 2001)SIDE EFFECTSInitially on the commencement of insulin people may experience sensitivity around the injection site.How would you recognise this?This is a form of allergy.It can be local, in which case the local cutis becomes red and itchy at the injection site.It may (rarely) be g eneral giving rise to a uticarial reaction, tachycardia and tachypnoea. Very rarely a patient may experience anaphylaxis.Symptoms of hypoglycaemia may occur if too much insulin is injected or if not enough carbohydrate is consumed or if there is increased exercise without taking extra food.Hard lumps under the skin may occur at injection sites if they are not rotated.What is the correct medical term for these?LipodystrophyThe number of units prescribed is calculated depending on time of day, age, weight and lifestyle.Typical paneling is 0.7-1.0 units per Kg of body weight.WARNINGSInsulin should never be administered in cases of HYPO.The body may get used to low levels of blood glucose and therefore the warning signs for HYPOs are reduced. Individuals who have lost these may be discuss to raise their blood glucose levels slightly for up to 3 months to resensitise themselves to symptoms. Some people have also found that they have lost some or all of their symptoms of HYPO when trans ferring from animal to human insulin.Insulin dosages may have to change if there is disease of the adrenal pituitary and thyroid glands and also in the presence of liver and kidney disease. Taking of steroids will increase the insulin requirement.During illness, puberty or emotional trauma glucose levels can become elevated and therefore insulin doses require to be adjusted and more regular blood sugar monitoring is essential.During pregnancy insulin requirements may decrease in the first trimester and increase in the second and third trimester.The following drugs may increase blood glucose levels and therefore lead to a need for more insulin SteroidsContraceptivesAsthma InhalersSome drugs lower blood glucose levels and therefore result in a reduction in insulin. These are-AspirinBeta blockersMono-amine oxidase inhibitors.There are four categories of insulin. Give an example of each.Very short acting ANALOGUE e.g. Humalog.Short acting SOLUBLE, NEUTRAL e.g. Actrapid, Human Velosul in.Medium and long acting ISOHANE, PROTAMINE ZINC e.g. Human Insulotard.Combination of short and medium acting MIXED, BIPHASIC e.g. Human Mixtard.Who would most likely be prescribed very short acting insulins?The very unstable or out of control diabetic. Children more likely than adults.How long before a meal does short acting insulin require to be injected?Depends on type. Sol. Insulin starts working within 30-60 mins and lasts about 6-8 hrs. Other types such as Insulin aspart and insulin lispro both start working within 15 minutes and last for up to five hours.The glucose rise after a meal typically begins within about 15 mins so the insulin should ideally be in the system to counteract it.How often chance(a) would you require to take the following insulins-Short acting about 2-4 times a day( when stable)Medium acting about twice a dayLong acting Once (or perhaps twice) a dayThese answers depend on the age and size of the patient, as well as the bad of the disease process.Why is short acting insulin sometimes given with medium acting insulin?To give a smoother blood glucose profile and also to fill in the gap before the medium acting insulin becomes biologically active.Where should insulin be stored?In the fridge, but not frozen.Briefly discuss the types of equipment that are used to administer insulin?Commonest is still the disposable insulin syringe. Syringe should always be calibrated to match the insulin type. Most are U-100 now.Other options include the pen devices (expensive but convenient and largely fool proof).Jet injectors are occasionally seen, but not very common.In hospital environs insulin pumps (drivers or infusers) can be used.Ambulatory subcutaneous pumps are increasingly used to deliver continuous infusion. Very expensive but arguably capable of producing the best control.(HSG 1997)What advice would you give to a diabetic who is planning to go abroad on holiday with regard to their insulin?Take plenty with you as your brand may not be available abroad.Make sure you can keep it refrigerated.Run your blood glucose levels slightly higher than you are used to a) because of probable increased exercise and b) to reduce the risk of Hypo whilst away from home.Be extra vigilant with the blood sugar monitoring. contrasted diet may have unexpected consequences.ORAL HYPOGYCAEMICSBelow are the main categories of drugs. Give an example of each, including daily dosage and side effects?SulphonylureasChlorpropamide250 mg (100 mg in the elderly)This is a very long acting drug, usually taken once daily with breakfast. Alcohol may cause flushing to the face.BiguanidesMetforminStart at 500 mg twice a day or 850 mg once daily. The maximum daily dose is 2550 mg given in three divided dosesGastrointestinal side effects are a common occurrence in people taking metformin. Problems often include bloating, flatulence, nausea, stomach cramps and diarrhoea everydayly a metallic taste in the mouth. Rare complication lactic acidosis(Knowler WC et al 2002)Prandial glucose regulatorRepaglinide0.5 to 4 mg with each mealOccasional gastro intestinal side effects(Bokvist K et al 1999)Alpha glucosidase inhibitorAcarbose50 mg then titrated against clinical effect.Flatulence soft stools or diarrhoea.Glitazones new drugRosiglitazone4mg as starting dose increasing to 8mg if requiredPossible toxic effects on the liver (theoretical rather than practical)(Park JY et al 2004)ACUTE COMPLICATIONSThe most common is Hypoglycaemia. It results from an imbalance between glucose intake, endogenous glucose and glucose utilisation.A decrease in the blood glucose level normally leads to stimulation of catecholamine secretion.

If minor, warm sweet (glucose containing) drinksIf major, IM Glucagon. Monitoring essential until fully recovered.What is ketoacidosis?A clinical condition almost invariably associated with low insulin levels. As a result, the blood glucose levels rise and the intracellular glucose levels fall. This requires the metabolism at a cellular level to be fuelled with fat derivatives rather than carbohydrates and this produces acidic ketones. These ketones normally require the presence of insulin for their catabolism. In its absence, they build up causing a metabolic acidosis and spill over into the urine when the concentration is high enough.Identify 5 causesFluctuations in insulin regimeIntercurrent illnessTraumaReduction in carbohydrate intake vapour +- severe exerciseState 10 clinical features of this clin ical stateHigh blood sugar levelsFrequent urination (polyuria) and thirstFatigue and lethargyDry skinFacial flushingNauseaVomitingAbdominal ailFruity odour to breathRapid, deep breathing (Air hunger)Muscle cruelness or achingComaThe principals of management are-Prompt administration of insulin (usually on a sliding scale) to reduce the hyperglycaemia and ketonaemiaReplacing mentally ill loss (from polyuria and vomiting) usually by intravenous fluidsRestabilising electrolyte imbalances secondary to dehydration, metabolic acidosis and hypokalaemia.Treatment for any underlying cause such as infection.LONG experimental condition COMPLICATIONSThere are 10 steps that the diabetic patient can take to reduce his chances of developing complications.Regular screening of BP and maintain at 140/80 or lower.Regular HbA1c testing.Maintain blood glucose levels between 4-7mmols/L before meals.A

Marxs Theory of Alienation

Marxs supposition of hallucinationIn my essay I forget attempt to demonstrate that patch dementia in existencey a(prenominal) respects seems of only limited use as a sentiment for judgement contemporaneous functional lives, it has been critical in moldable our legitimate lowstanding and practices of fail. I int overthrow to look at the lend of Karl Marx among otherwise sociologists to show how the introduction of capitalist economy into industrial proceedsion in busy adjust relishings of derangement in destinyess cash in wholenesss chipsss lives. I fork up chosen to specifically focus on Marx as I find his thoughts and ideas on alienation to be of key importance in our current understanding of wear down. I will principally be looking at his Alienation Theory, which was his belief that our excavate in society developed different forms of alienation, and how, if at all, this determines our inherent human being. I plan to assess whether theories on aliena tion at work atomic number 18 still relevant in juvenile society, and how they have contri only ifed to our current understanding of contemporary working lives.Work, in its somatogenetic features and its linguistic description is affablely constructed there is no permanent or objective thing called workwhat counts as work go offnot be severed from the background at heart which it inhabits, and that context necessarily changes through space and time (Grint, 1998, 11).Karl Marx believed crunch was at the heart of humanity, and that the conditions under which we work can vary. He tangle that alienation was a systemic effect of capitalism which exploited proletarians and acquired a wiz of isolation in peoples working lives. He believed that under a capitalist regime workers unavoidably lose any control they have over their lives by having the control over their labour taken out from them. According to Marxs Alienation Theory, there atomic number 18 four forms of alienatio n in labour, the first being alienation from the product of work. Marx states that when a worker is producing something for someone other than themselves, especially when they do not even know who they be producing the item for, the product often fails alien to them. In this situation the worker will not have any unrestrained connection with the end product they have created. In this way Marx gives the worker a involve connection to the product, which in turn, alters it from being simply an abstract object. Furtherto a greater extent, Marx refers that the product, which he believes ought to create a positive connection, instead holds a negative disconnection. According to Marx, when a person works for others and not for themselves they can be seen to be working in an alienating situation simply to receive their canonic requirements to expire by.Marxs second form of alienation is alienation from the activity of work. This alienation occurs as a result of the worker being e stranged from the product they create, as this subject matter they must also be alienated from the carry through they undertook to shuffling it. Marxs aversion to capitalism is linked to this possible action which proposes that as humans are working solely for survival, the work is required of them by others and so not natural. In which case the worker will not be working for themselves only instead for others and so will inevitably become alienated from the process of work.The third form of alienation is alienation from species being, meaning people become detached from their personal creativity and in a signified the heart of humanity. Marx discovers that the activity of work requires workers spiritual energy and accordingly when a worker is alienated from the practice of work it is impossible for them to give themselves full to their work hence change state alienated from their basic human roots. If the process of labour which is in our innate essence becomes alien to us, then we whitethorn become alien to ourselves in some way. Marx attempts to convey that work is something that ought to be a natural instinct to humans, not something carried out purely for survival. He refers to humans as active producers which contradicts the idea of people being alienated from their working lives. When a worker is forced to produce something for others and not for themselves they will see labour purely as a means of survival which will become a burden they are forced to monotonously repeat and hence may end up becoming alienated from themselves.The fourth and final form of alienation in Marxs Alienation Theory is alienation from others. When a worker is forced to produce a product for someone else they too will become alien to the worker, and so in this way people become alienated from other humans, which can maneuver to a breakdown in society. This can give rise to a type of hostility as the worker may feel they are required to do work for others with more than cultural capital and so a class division can arise. Marx says of this form of alienation,If man is tie in to the product of his labor, to his objectified labor, as to an alien, hostile, male monarchful object in restricted of him, he is so related that another alien, hostile, forceful man independent of him is the lord of this object. If he is unfree in the relation to his own activity, he is related to it as bonded activity, activity under the domination, coercion, and yoke of another man (Marx, 1844, 57).So, how useful is this theory of alienation as a imagination for understanding contemporary working lives? Marx likens humans to animals only doing what we must to survive. In an ideal world we would enroll in work for the love of it as we believe it is meaningful and valuable. Marx claims that under capitalist industrial business systems in society people become alienated at work as a result of their departure of control. Capitalism creates a system where by the worke r gives more power to the capitalist by producing better products. So it can be seen that the more the worker produces the more they must rely on that product. Marx says,Labour, to be sure, produces improbable things for the rich, but for the labourer it produces privation. It produces palaces for the wealthy, but hovels for the worker. It produces beauty, but cripples the worker. It replaces work by machines, but it throws part of the workforce back to a barbarous kind of work, while turning others into machines. It produces sophistication, but for the workforce it produces feeble-mindedness and idiocy. (Marx, 1844, 30)The relevancy of Marxs theory today seems limited. It is light(a) to see that at the time of Marxs writing a large impart factor to alienation at work in the 19th one C was the revolutionary form of labour named Fordism, which refers to the production methods used by heat content Ford in creating the Ford cars. C20th Marxist Antonio Gramsci often used the moral of Fordism in his work on mass production and consumer culture. Ford was intemperately influenced by Frederick Taylor who developed scientific management, and aimed to ameliorate labour productivity. The system was created to improve productivity and enable mass production it was self-made in tart the cost of production but also heavily deskilled labour. It saw a high turnover rate of staff and prompted numerous strikes due to workers enemy to speed control and oppressive forms of work. It took any control away from the workers by making them work to the pace of the assembly line on surmount of this workers rarely got to see what they were making as each worker would be in charge of such a small part of the conglomeration creation of the product. Workers often complained the labour was solely approximately profit creator and their power was completely subsumed by the managers who deskilled the workers to gain control and eliminate their power and decision making.Scientific management so called is an attempt to apply the methods of science to the speedily increasingly complex problems of the control of labour in rapidly growing capitalist enterprises. It lacks the characteristics of a true science because it assumptions reflect nonentity more than the outlook of the capitalist with regard to the conditions of production (Braverman 1974, 86). merely work today is far broader than mass production in a grind setting. In her article Alienation and New Work Practises Reconstructing a mere Concept Amanda Damarin argues,Existing concepts of alienation are inadequate for capturing the relationships among workers, tools, and labour processes that exist in new work organizations. Marx assumes that production is industrial (standardized and fixed), that employers own the means of production, that ownership is coextensive with control, and that only relationships between workers and employers are significant in shaping the experience of work. (Damrin, 2005, 2).One need only think about the growth in the service sector or indeed the wellness care industry to realize that Marxs Theory of Alienation is deficient in fostering our understanding of contemporary working lives. For example, he focuses principally on the labour form of manufacturing, whereas if we were to look at retail Marxs description of the 4 forms of alienation seems less(prenominal) pertinent. In retail there is no product being created in the stigmatise and so less chance of shop assistants to feel alienated from it. Likewise although they may be selling to others it would neer be the case that they would sell to themselves so they are less fain to feel alienated from their fellow man. They can experience contact with the customers but not feel like they work directly for them so in this way I believe there wouldnt be predominant olfactory perceptions of isolation. But if Marxs theory about the forms of alienation can take seem less relevant to todays working environ ment one cannot ignore the fact that work can indeed leave people feeling isolated or powerless.Marx forecasts work as central to the human experience. But why does man work? Looking to Maslows Hierarchy of Needs, we see employment fulfilling level 2 Safety needs but also, beyond that, our need for Love and be can often be met via work. Even people in the roughly mundane of jobs often look to their co-workers as valuable providers of community. Marx posits that proper work (that is not under a capitalistic regime) also provides people with a sense of self-worth and achievement. But clearly this is true in current day working lives, even in capitalistic economies. Indeed Durkhiem, contrary to the views of Marx and Engels, gave a positive analysis of the industrial society, with less emphasis on capitalism. He spoke of a more heterogeneous society and a more segregated division of labour where people are more dependent on one another. This interdependence he felt brought people un neurotic as you have to go to others to receive the necessary products for daily life. So society was viewed more as a body that functions together as a whole.It is important to remember that Marxs alienation theory was part of his earliest work and possibly an opening thought into his later more developed work on capitalism as an economic structure within society. If it is true, as I believe, that many of Marxs theories have significantly less relevance since advancements made after the industrial revolution, I believe it is equally true that much of his work on alienation has been crucial in shaping our contemporary understanding and practices of work. For example even in todays factory setting, workers are now often asked for their opinions and suggestions to improve conditions at the work place. And with 360 degree feedback becoming the norm in the Western workplace, workers can comment on their managers performance too which gives them a sense of control over their working con ditions and allows their parts to be heard. It is not inconceivable to imagine that the introduction of worker voice was support by Marxs concerns about alienation. In fact a highly advantageful British retailer, John Lewis Partnership, which I worked at for several months, was founded on the principles of gibe employee ownership with the thought that this would create a direct link to the success of the business. save these improved environments in work places are witnessed predominantly in Western countries factories in the developing world can be seen to maintain conditions much more akin to that of the 19th century factories in Europe.If one accepts Marxs premise that work is central to humans as a basic form of self realization then it isnt difficult to understand how the privation of employment can be equally isolating. Although people may feel alienated at work Braverman points out unemployment is even more corrupting and isolating. In their study, Your Job No Longer E xists From Experiences of Alienation to Expectations of Resilience Vickers and Parris suggest We have entered the age of the contingent or temporary worker where we are expected to be pliable and tractable to fit in (Vickers and Parris, 2007, 114). For example, when a worker is fired from their job, there are often associated feelings of rejection and alienation which can be agonizing. They claimed alienated workers tend to experience similar emotions, including powerlessness and social isolation as well as shock, betrayal, humiliation and shame (Blauner 1964, 101).So as working lives are constantly changing and being adapted to suit contemporary society the very concepts that Marx used to portray the evils of capitalism may indeed be helpful in understanding reactions to the overtaking of that central source of self realization, work.I strongly feel although Marxs passkey ideas about alienation at work appear overly focussed on 19th century working conditions, particularly in the mass production manufacturing world, the concept is not without merit in understanding how contemporary workers may come to feel a sense of isolation or powerlessness via work. Marx may have taken an overly critical view of capitalism but in doing so he no disbelieve opened the door for a wider recognition of the importance of worker voice and engendering a sense of belonging or value to individual labour. Braverman has delicate his debt to Marxs work on capitalism and alienation at work, and although he has not contributed much in the way of innovative theories on the topic he can be seen to renew Marxs work in modern society. The Managed life demonstrates Hochschilds vigorous application of Marxs alienation theory while condemning the feeling of alienation experienced as a result of the comodification of human emotions. However I have to wonder whether this comodification of feelings directly results in alienation. Both Bolton and Boyd externally reject the idea of emotional l abour as contending with wage labour as they believe not all peoples feelings are necessarily comodified during the labour process. They argue that workers have a relatively large amount of emotional choice due to the narrow degree that their emotions can be comodified, and therefore wouldnt experience much alienation at work in the sense Hochschild refers to. Overall I believe in many ways alienation appears to be only of limited use as a concept for understanding contemporary working lives however through the work of such sociologists as Marx it has been essential in moulding our existing understanding and practices of work. neo society has a much broader spectrum of work than just mass production in factories but with the work of sociologists such as Gramsci and Braverman who have make on existing ideas of alienation by Marx and others we can continually modify our knowledge and increase our understanding of contemporary working lives.Word list 2,847

These stakeholders commence different perceptions as to what constitute success . enchantment they all confound different responsibilities towards the success of the game, their individual objectives has to be met. It is worth noting that their change objectives were well reconciled as per the game. Shared understanding was created among them and rapprochement of objectives was easy because one of the predominant overarching aims of both the UK government and IOC for the games is sustainability among the Consultant, the main Contractor, the Sub-Contractor and the Supplier.The more details including the Appendix-A2.2. Financing building/Final CostThe financing structures are two distinct aspects of the London 2012 Olympic Games, the preparation for the games by the ODA and LOCOG operational compute running the games.The Secretary of state for culture, media and sport announce, in an unwritten Statement to the house, that the reckon for the preparation of the 2012 London Olympics had increased from an initial try budget of 2.375 million, at the time of the bid the estimated embody of the Games was 4 billion 3 billion for the Olympic Park and an element for elite and club sport and 1 billion as classify of the wider Lower grass Valley regeneration (excluding tax and wider security costs).Following a review by the Government a revised funding cost was announced in March 2007 of 9.325billion, as details below dodge-01.The work out as Announced for the Games on 15 March 2007 degreeDescription quantity Million ()1Core Olympic Costs -Olympic Delivery Authority(ODA)3,081.002Infrastructure and regeneration costs associated with the Olympic park and other venues1,673.003 contingency (Excluding Tax)500.004 good ( Net of Tax )(1+2+3)5,254.005 other(a) (Non ODA),Olympic Cost388.00Other ProvisionsPolicing and Wider Security600.00Tax (on ODA Costs)836.00 just general programme Contingency (including tax)2,247.006 quantity Provisions3,683.00Grand Total (4+5+6)9,325.00Overall Revised Budget9,325.00Table -01The 2012 Olympic Games over-a ll budget (9.325 Billion () were distributed to all stockholders and summarized as follows on Table-02.Public Funding obtainableItemDescriptionAmount Billion ()1Exchequer5.9752National Lottery2.1753Greater London Authority0.9254London Development Agency0.250Total Cost(1+2+3+4)9.325Table -02However, on 24 March 2010, the Awarded budget was reduced to 27m and breakdown as follows Table 03ItemDescriptionAmount Million ()1Olympic Delivery Authority(ODA)ODA Base Cost Including VAT6,100.00Programme Contingency968.00Funders Contingency1,004.00Total Available to ODA8,072.002Non-Olympic Delivery Authority(ODA)Elite and Community Sports290.00Paralympic Games66.00 olfaction of London32.00Security600.00Security Contingency238.00Total Non ODA1,226.003Total Public Sector Funding Package (1+2)9,298.00Overall Original Budget9,298.00Table -03The 2012 Olympic Games over-all Revised budget (9.298 Billion () were distributed to all stockholders and summarized as follows on Table-04.Sources of Funding ItemDescriptionAmount Billion ()1National Lottery2.1752London (GLA and LDA)0.8753Central Government6.248Total Cost(1+2+3)9.298Table -04Unveiling the governments last-place quarterly budget update, the sports minister, Hugh Robertson, said that at a conservative estimate the final cost of the Games would be 8.921billion against an overall original budget of 9.298billion2.3. Project Procurement Structure/MethodologyThe specific tonic construction of Olympic stadium, the project lead has been established, and then the procurement method will be accepted. The project was procured on a design and build basis.A method where the contractor is answerable for undertaking both the design and the construction of the work in give back for a lump sum price.There are variants on this extract depending on the degree to which initial design is included in the clients requirements. escort of a contractor is often by two stages tendering, thus belongings a competitive element, but not expecti ng every tenderer to produce full proposals. The clients requirements can range from a simple accommodation schedule to a fully worked out scheme design, but generally should be matched by the contractors proposalFor design and build procurement there are terce main types of contractPackage Deal or Turnkey ContractDesign and Build Contracts Contractors Design ObligationsContractors Design for Specific Elements OnlyThe project procurement plan includes the followingSourcing materials with low embodied carbonMinimizing elope at source, promoting use of secondary materialsPolicies on ecoEcologically sensitive materials e.g look and FoodEthical procurement and fair employmentSourcing healthy materials and ensuring health and resort on site (ODA, 20091)The procurement plan is being implement by a rigorous procurement process. All partners and collaborators will have to cope with individual and overall criteria in order to contribute to the successful outcome of the plan. This wil l have to be made visible through product and service supply, engagement in relevant projects, promotion of behavioral adjustment, consumers, employees and supply chains (ODA, 2009).2.4. Main Forms of Construction Contract/Tender DocumentThe New Engineering Contract (NEC) was used to facilitate all the requirement documents during the bidding and awarding stage. Both parties, the Client and the Contractor, agreed and closed the project based on the NEC contract.The NEC3 suite of contracts was selected because it provided the following key attributes in response to ODA, s Requirements.A flexible approach, providing a range of contract solutions relative to the level of design information available and procurement survival being considered.The pro-active management of risk as an inherent and fundamental element of the entire contract forms.A collaborative approach supporting seasonable delivery, which is fundamental to ODA.Full visibility of cost (Except under option a contracts), supporting effective programme budget management.ODA has number of obligations under the London Olympic Games Act 2006, particularly around risk, brand protection and stakeholder rights, which necessitated changes to the measuring stick NEC3 Contract Forms.

Chapter3.1. Construction Technology ChallengesThe London 2012 Olympic Games project was constr ucted with more construction challenges and innovative construction technologies. Some of which are as follows Low-carbon concrete with 40 percent less embodied carbon was used for concreting structures.Surplus atom smasher pipes were used to build the top ring of the Stadium.Recycled containers were used as commode facilities.Demolished existing structures were placed on top of the ground that served as a solid base for the construction.To reduce the loads on the project, 75 percent lightweight steel materials were utilized in the construction.As part of the landscaping works. 500,000 plants were planted in the Olympic Parks wetland areasDue to new technologies that were adopted, only 10,000 tons of steel were used.Tensile roofings were used as to crosscut the ground bowl-like stadium.The project settled at 2,821 feet perimeter land and stands at 197 feet high.The Delivery Partner was comprised of three construction industry leaders, who were responsible for the construction o f all new venues and infrastructure needed for the London 2012 Olympic and Paralympic Games. The Olympic Park will house nine state-of-the-art venues including the Olympic stadium, velodrome and water sport center. New Technology was used to fast track the project and attain the completion date of the Project.As the time is the essence, the constructions were done on a 24 hour basis as the design required new methodology to meet the criteria of the Project SpecificationsMethodological challenges that are anticipated includeAchieving adequate coverage of project-level evaluations, within the bounds of practicality, across legacy and sub-legacy themes, geography, demographics, project size/type etcThe complexity of the task and the interdependencies that exist between outcomes and impacts of different projects and programmesThe aggregation and synthesis of different measures and indicators, which may also be of varying qualityAssessing the impact and additionality of interventions in a consistent fashionEnsuring esteem for money and benefits are being measured or estimated using credible evidenceMeasuring intangible impacts using experimental measures such as subjective well-being and through custom techniques such as media marrow analysisMeasuring wider strategic impacts and added value generated through coordination of the organisations involved in planning and delivering legacy3.2. Health and Safety Records/AchievementThe HSE has published the initial in a series of research reports on the London 2012 Olympics as part of a concerted effort to circulate the health and safety lessons learned from the Stratford project among the wider construction industry.There are so many magnificent aspects of London 2012 when it comes to Safety issues and this was achieved through the excellent safety book, curiously during the construction phase.The park was built with zero construction fatalities. It shows the approaches to gain a good occupational Safety and Health . Some of the achievements are as followsThe Royal Society for the Prevention of Accidents (RoSPA) honored the Olympic Delivery Authority in a ceremony.More than 12,500 workers helped construct the venues and the Big Build of the site was hailed as the safest construction of an Olympic Stadium.The Executive started working with the Olympic Delivery Authority (ODA) soon after London was awarded the 2012 Olympic and Paralympic Games and set out gather targets of what standards were expected, encouraging strong leadership and sharing of good practice. Up to this month, the HSE has authentic reports of only 114 injuries and eight dangerous occurrences that occurred during the projects 66 million hours of work.And also the ODAs commitment to health and safety has been recognised by the British Safety Council (BSC) with its 5-star award, following an independent, rigorous audit of the ODAs health and safety management system and processes, in which the ODA received a score of 98 per cen t.The ODA was also awarded the Sword of Honour, one of the most prestigious international health and safety accolades that an organization can receive, which is designed to encourage and reward organizations that work to best practice. All applicants must have already received 5 stars from the BSC04. Chapter4.1. ConclusionBased on the above submission, it can be concluded that the Construction of the facilities needed for the 2012 London Olympic Games were successfully done and completed to the satisfaction of the Client. This achievement was due to the followingThorough evaluation of the Project Requirements as reviewed and evaluated by the Client.An organize procurement strategy within the UK and International market environments.Teamwork and coordination among the stakeholdersUtilizing the familiar form of contract in UKProper implementation of all construction methodology accepted in the construction industry.Proper planning and implementation to meet the required completion d ate.Utilizing new construction technologies and materials.Likewise, a complete record for health and safety were properly organized. A strict implementation of a Safety Plan were followed resulting to no fatalities or major injuries recorded.With respect to the pecuniary aspect of the project, variation orders and cost were not clearly indicated as this will have a big impact on the total and final cost of the project involved.Nevertheless, the over-all aspect of the report can be recommended as it clearly shows that all necessary strategies and construction methodology will have a successful outcome as expected by the client specifically the completion of the project as per the time schedule, work quality and project cost.05.

Luteolin and Kaempferol From Cassia Alata

Luteolin and Kaempferol From genus cassia AlataLUTEOLIN AND KAEMPFEROL FROM CASSIA ALATA, ANTIMICROBIAL AND ANTIOXIDANT ACTIVITY OF ITS METHANOLIC EXTRACTSANEELA WAHAB, TAHIRA, SABIRA BEGUM, ANJUM AYUB, IFFAT MAHMOOD, TALAT MAHMOOD, AQEEL AHMADAND NIDA FAYYAZAbstractCassia alata alike cognize as candlebush is a medicinally important prove. In the present probe we are reporting the closing off and structure elucidation of two flavonoids kaempferol (1) and luteolin (2) apart(p) from methanolic extract of its beans through bio canvas guided ingredientation. The structure of isolated compounds were characterized by spectroscopic techniques such as EIMS, 1H-NMR and 13C-NMR. In this article we are similarly presenting the bactericide, antifungal and antioxidant practise of the methanolic extract of its leaves (CA-L), stem turn (CA-S) and beans (CA-BN). completely the extracts showed remarkable antibacterial and weak antioxidant use whereas moderate antifungal activity was who le free-base in stem (CA-S) and beans (CA-BN) extracts.IntroductionCassia alata (Synonym Senna alata) belonging to the family Leguminosae and subfamily of Fabaceae, commonly known as seven lucky candlesticks, and ringworm senna (Quattrocchi U., F.L.S., 2012). This plant is primordial to the West Indies, tropical America, found wild almost throughout India and Pakistan (Khare C.P., 2007). C. alata with golden blooms is a summer bloomer and a striking spring that brave out for several weeks but prefer cooler month for flowering (Ray A.B., et al., 2010, Krishnan M. K. S., 1992). This pubic hair may grow up to 3 meters tall with irregular, angled, glabrous branches. Flowers bedevil bright yellow colour. It has long, membranous, dehiscent fuel pods with 25 or more seeds per pod (Ross I.A., 2003, Bhattacharjee S.K., 2004).Cassia alata is widely apply as traditional medicine in India and Southeast Asia ( Reezal I., et al., 2002 ). This plant is report to possess insecticidal, anti -inflammatory, hydragogue, sudorific, diuretic, pesticidal properties. Fresh leaves juice is employ for ring worm, snakebite, scorpion bite, skin diseases, impetigo, syphilis sores, itching, mycosis (washermans itch), herpes and eczema. Roots, leaves and flowers of this plant possess many biological properties such as antibacterial, antifungal, anti-inflammatory, antitumor, expectorant and also useful in urinary tract problems (Quattrocchi U., F.L.S., 2012), asthma, bronchitis and constipation (Joshi S.G., 2000). The ethyl acetate rayon extract of C. alata leaves possess hypoglycaemic activity (Ray A.B., et al, 2010). This plant also has hepatoprotective property. The principal(prenominal) constituents of C.alata are flavonoids, alkaloids, anthraquinone derivatives, tannins, sterols and triterpenes (Neharkar V.S., Gaikward K.G., 2011). The present paper describe the isolation and characterization of kaempferol (1) and luteolin (2). herein we are also reporting the antimicrobial a nd antioxidant activities of the methanolic extract of leaves, stem and beans of this plant. entirely the extracts showed epochal antibacterial ( bow 2) and weak antioxidant activity ( elude 4). Antifungal activity ( hold over 3) was only observed in the extract of stem and beans.Experimental literals and MethodsGeneral silicon dioxide gel PF254 (Merk) was use for vacuum liquid chromatography (VLC). Thin layer chromatography (tender loving care) was performed on pre-coated silica gel F254 (Merck). Gel permeation chromatography was performed on sephadex LH-20 (Pharmcia). The EIMS (electron impact piling spectrometery) were scanned on Jeol-JMS HX-110 potful spectrormeter. The 1H and 13C-NMR (Nuclear Magnetic Resonance) spectra were recorded on a Bruker spectrometer operating at 300 and 75 MHz respectively. The chemical shimmy values are reported in (ppm) relative to SiMe4 (Tetra methyl silane) as an internal standard. The twin constant (J) is given in Hz.Plant MaterialThe Cassi a alata was collected from Karachi (Sindh) and place by Mr. Ghulam Rasool. A voucher example (86464) has been deposited in the herbarium at Department of Botany, Faculty of Science University of Karachi, Sindh Pakistan.Extraction and isolationThe air dried leaves (7 kg), stem (5 kg) and beans (5 kg) of Cassia alata were extracted repeatedly with methanol at room temperature. The solvent was evaporated under vacuum to give 2 kg crude extract of leaves (CA-L), 3 kg crude extract of stem (CA-S) and 750 g crude extract of beans (CA-BN). The dark greenish brown pastelike crude extract of beans (CA-BN) was partitioned with ethyl acetate (EtOAc), water ( phonograph recordingard) and n-butanol sections. Each fraction was concentrated in vacuum to have 15 g EtOAc and 15 g n-butanol soluble fractions. The EtOAc soluble fraction was further partitioned with n-hexane to obtained n-hexane soluble fraction and n-hexane insoluble fraction. The n-hexane soluble fraction (14 g) was subjected to vacuum liquid chromatography (VLC) (n-hexane n-hexane EtOAc in golf club of increasing polarity) which furnished 22 fractions (Fr-1-Fr-22). The Fr-15 was subjected to reverse-phase editorial chromatography development sephadex column LH-20 (CHCl3CHCl3MeOH in beau monde of increasing polarity) which yielded 12 fractions (Fr-15-1-Fr-15-12). The Fr-15-9 was further subjected to reverse phase column chromatography using sephadex column LH-20 (n-hexaneCHCl3MeOH in order of increasing polarity) furnished 18 fractions (Fr-15-9-1-Fr-15-9-18). The Fr-15-9-10 eluted with n-hexaneCHCl3MeOH (0.531.5) gave yellow amorphous powder which showed single spot on TLC using CHCl3 MeOH (9.20.8) as a solvent system was identified as kaempferol (1) (37 mg). The Fr-15-9-9 was further subjected to reverse-phase column chromatography using sephadex column LH-20 (n-hexaneCHCl3MeOH in order of increasing polarity) which yielded 13 fractions (Fr-15-9-9-1 to Fr-15-9-9-13). The Fr-15-9-9-3 eluted with n-hexan eCHCl3MeOH (0.531.5) showed single spot on TLC (CHCl3MeOH, 9.20.8) appeared as yellowish powder and was identified as luteolin (2) (27 mg).Biological assayScreening of antibacterial activityThe disc dispersion manner (Bauer et al, 1966) was used to determine the antibacterial activity of methanolic extracts. 100 mg/ml of declivity solution was on the watch by dissolving extracts in DMSO. Sterile deform discs containing 10 l of stock solution were used for screening. The Mueller Hinton agar (Oxoid) plates were seed with 24 hours old culture grown in Mueller Hinton broth (Oxoid). The prepared discs were fit(p) onto the surfaces at different positions and plates were incubated at 37C for 24 hours. Results were recorded by measuring the zone of curtailments in mm. Gentamicin was used as a standard.Screening of antifungal activityAntifungal activity was also determined by disc diffusion method (Bauer et al, 1966) as above. Briefly, a small amount of culture was transferred to 2-3 ml distilled water or normal saline in a screw capped piping with few glass beads (1 mm in diameter) and vortexes for 5-10 minutes to substantiate a homogeneous suspension of fungal culture. Sabouraud dextrose agar (SDA) plates were seed with this suspension. Sterile filter discs containing 10 l of stock solution were placed onto the surfaces at different positions. Plates were incubated at room temperature for 1 week. Results were recorded by measuring the zone of inhibitions in mm. Gresiofulvin was used as a standard. goal of minimum inhibitory concentration (MIC)MIC of methanolic extracts were determined by the disc diffusion method ( Bauer et al, 1966).Sterile discs containing different concentrations of try outs varying from 0.98 to 1000 g per disc were prepared. The MIC of those extracts showing maximum zone of inhibition against microorganism were calculated ( Table 2 ).Antioxidant activityAntioxidant activity was determined by using the method described by Lee et al. (1 998). 1,1-diphenyl-2-picrylhydrazyl (DPPH) was prepared in ethanol (300 M). 10 L of each extract and 90 L solution of steadfast radical, 1,1-diphenyl-2-picrylhydrazyl (DPPH) was added in 96 well micro titer plates and incubated at 37 C for 30 minutes. Absorbance was measured at 515 nm by using a spectrophotometer. Percent inhibition of radicals by treatment of test sample was determined by comparison with a DMSO treated control group.% stifling = (absorbance of the control-absorbance of the test sample) x 100Absorbance of the controlAscorbic acid was used as standard control. The EC50 value calculated denotes the concentration (in ug/ml) of sample required to clean house 50% of DPPHCharacterization of Kaempferol (1) jaundiced amorphous powder. 1H-NMR (300 MHz, CD3OD) 8.09 (2H, d, J = 8.7 Hz, H-2, 6), 6.91 (2H, d, J = 8.7 Hz, H-3, 5), 6.43 (1H, d, J = 1.8 Hz, H-8), 6.19 (1H, d, J = 1.8 Hz, H-6). EIMS m/z 286 M+. 13C-NMR (see Table 1). All data were identical with that of reporte d in literature (Hadizadeh F., et al, 2003, Gangwal A., et al, 2010).Characterization of Luteolin (2)Yellow amorphous powder. 1H- NMR (300 MHz, CD3OD) 7.39 (1H, dd, J = 9.0, 1.8 Hz, H-6) ,7.36 (1H, d, J = 1.8 Hz, H-2), 6.88 (1H, d, J = 9.0, Hz, H-5), 6.53 (1H, s, H-3), 6.43 (1H, d, J = 1.8 Hz, H-8), 6.19 (1H, d, J = 1.8 Hz, H-6). EIMS m/z 286 M+. 13C-NMR (see Table 1). All data were identical with that of reported in literature (Saeidnia S., et al, 2009).Results and discussionThe phytochemical investigation of the methanolic extracts of Cassia alata beans resulted in the isolation of kaempferol (1) and luteolin (2). Compound (1) showed molecular(a) ion peak at m/z 286 having molecular formula C15H10O6. Its 1H-NMR spectrum showed the characterstic peak of H-2 and 6 as a doublet at with ortho coupling of 8.7 Hz whereas H-3 and 5 with similar ortho coupling appeared at 6.91 as a doublet.1H-NMR spectrum of 1 further displayed signals of aromatic protons as a doublet at 6.19 (H-6) and a t 6.43 (H-8) showing meta coupling of 1.8 Hz.The EIMS spectrum of compound (2) is similar to (1) having same molecular mass (m/z 286) and formula (C15H10O6). In the 1H-NMR spectrum of 2 characterstic peak of H-3 appeared at 6.53 as a singlet. Other important signals observed at 6.88 (d, J = 9.0, Hz, H-5), 7.36 (d, J = 1.8 Hz, H-2) and 7.39 (dd, J = 9.0, 1.8 Hz, H-6). The aromatic protons H-6 and H-8 showed same and J value as in compound 1. The 13C-NMR spectrum (Table 1) of both compounds 1 and 2 displayed signals of nine quaternary and half dozen methine carbons . All the 13C assignments are in agreement with the reported data (Gangwal A., et al, 2010, Saeidnia S., et al, 2009).The results of antibacterial activity indicated that all the methanolic extracts of C. alata (CA-L, CA-S and CA-BN) have authorization to kill sundry(a) pathogenic gram+ve and gram-ve bacteria (Table 2), whereas good antifungal activity was observed in CA-S and CA-BN extracts against Fusarium specie (Ta ble 3). All the extracts (CA-L, CA-S and CA-BN) showed less than 50% inhibition of DPPH radicals in antioxidant activity (Table 4).CONCLUSIONThe known flavonoids kaemferol (1) and luteolin (2) were isolated from the methanolic extracts of C. alata beans. The structure of the isolated compounds were elucidated by various spectroscopic techniques. Pharmacological investigations have indicated that all the extracts (CA-L, CA-S and CA-BN) of this plant possess significant antimicrobial and weak antioxidant activity.ReferencesBauer, A.W., Kirby, W.M.M., Sherris, J.C., Turck, M.
