Alfred Sisley, French Impressionist Landscape Painter
Alfred Sisley, French Impressionist Landscape Painter Alfred Sisley (October 30, 1839 - January 29, 1899) was a French impressionist painter who straddled British and French national identification. Although he received far less praise than some of his contemporaries, he was one of the key artists who began the French impressionist movement. Fast Facts: Alfred Sisley Born: October 30, 1839 in Paris, FranceDied: January 29, 1899 in Moret-sur-Loing, FranceProfession: PainterSpouse: Eugenie LesouezecChildren: Pierre and JeanneArtistic Movement: ImpressionismSelected Works: The Bridge in Argenteuil (1872), Regatta at Molesey (1874), Barges on the Loing at Saint-Mammes (1885)Notable Quote: The animation of the canvas is one of the hardest problems of painting. Early Life and Training Born in Paris, France, the son of wealthy British parents, Alfred Sisley grew up and lived most of his life in France, but he never renounced his British citizenship. His father operated a business exporting silk and artificial flowers. Sisleys mother was extremely knowledgeable about music. In 1857, the parents sent young Albert to London to study for a career in commercial trade. While there, he visited the National Gallery and examined the work of the painters John Constable and J.M.W. Turner. In 1861, Albert Sisley returned to Paris, and a year later began art studies at the Ecole des Beaux-Arts. There, he met fellow painters Claude Monet and Pierre-Auguste Renoir. They frequently took trips to paint landscapes outdoors in an effort to realistically capture the changing impact of sunlight throughout the day. Sisley met Eugenie Lesouezec in 1866. Together, they had two children, Pierre, born in 1867, and Jeanne, born in 1869. Although they remained together until Eugenies death in 1898, they didnt marry until August 5, 1897. In 1870, due to the impact of the Franco-Prussian War, Sisleys fathers business failed. Sisley and his family lived in poverty for the rest of his life, surviving on the income from selling his paintings. The value of his works didnt increase significantly until after his death. The Seine at Point du Jour (1877). Hulton Fine Art / Getty Images Landscape Painter Camille Pissarro and Edouard Manet were primary influences on the style and subject matter of Albert Sisleys paintings. Pissarro and Manet were key figures who provided a bridge to the development of impressionism in the latter part of the 19th century. Sisleys primary subject was landscape painting, and he often depicted dramatic skies. The painting The Bridge in Argenteuil, painted in 1872, shows Sisleys primary interest in the landscape and architecture of the bridge despite the presence of strolling people in the painting. He boldly depicts the clouds in the sky and the rippling effect of waves in the water. The Bridge in Argenteuil (1872). Mondadori Portfolio / Getty Images Barges on the Loing at Saint-Mammes, painted in 1885, shows the bold colors created by the intense sunlight of a warm summer day. The reflections of the buildings along the beach are shown broken up by the movement of the water, and the eye is drawn through perspective to a railway viaduct in the distance. Friendship With Pierre-Auguste Renoir and Claude Monet Alfred Sisley became close friends with Pierre-Auguste Renoir and Claude Monet, two of the most prominent impressionists. The trio often painted and socialized together. Sisley was close enough to Renoir that the latter painted multiple portraits of Sisley both alone and with his partner, Eugenie. Albert Sisley painted by Pierre-Auguste Renoir. Yorck Project / Wikimedia Commons / Public Domain Sisley was never as prominent in the Paris art scene as his two close friends. Some observers theorize that is due to the fact that Sisley insisted on embracing both his French and British roots, straddling two cultures, while his better-known colleagues were French through and through. Later Career Constantly seeking a lower cost of living due to struggling to get by on his income from selling paintings, Sisley moved his family to small villages in the French countryside. Late in his career, he began focusing more intently on architecture as a subject in his art. An 1893 series of paintings focuses on a church in the village of Moret-sur-Loing. He also painted a series of depictions of the Rouen Cathedral in the 1890s. Barges on the Loing at Saint-Mammes (1885). Heritage Images / Getty Images Albert and Eugenie traveled to Great Britain for a final time in 1897. They married each other in Wales and stayed along the coast where Sisley executed nearly 20 paintings. In October, they returned to France. Eugenie died several months later, and Albert Sisley followed her to the grave in January 1899. To assist with the financial needs of the children Sisley left behind, his good friend Claude Monet arranged an auction of the artists paintings in May 1899. View of Fontainebleau Wood (1885). Mondadori Portfolio / Getty Images Legacy Alfred Sisley received little acclaim during his lifetime. However, he was one of the founding artists of French impressionism. His early paintings provide a link between the neo-impressionistic works of artists such as Edouard Manet, and key impressionists such as Claude Monet and Pierre-Auguste Renoir, both good friends of Alfred Sisley. Some also see Sisley as a rightful predecessor to the work with light and color in the paintings of Paul Cezanne. Source Shone, Richard. Sisley. Harry N. Abrams, 1992.

Balance sheet Essay Example | Topics and Well Written Essays - 1500 words
Balance sheet - Essay Example It can also help managers to establish policies and strategies for the future. This paper provides information about the importance of balance sheet and its uses for investors and management. It also provides an insight into the ratio analysis that could be done on the basis of information obtained from balance sheet. The paper shows calculation and analysis of ratios from the balance sheet of Palaron Plc so as to understand the usefulness of information presented in the balance sheet for investors. Balance sheet plays a vital role in depicting the financial position of a company. It further shows whether an investor should invest in a particular company or not. A company's balance sheet also shows the strengths and weaknesses of a company. A company through its balance sheet portrays its financial position to the investors that it is a reliable company that possesses prosperous prospect and chances to grow. It also reflects whatever the goals have been set by the company will definitely be accomplished and delivered to the investors in the shape of cash or stock dividends. Birts also says that "the company must demonstrate its ability to trade for some time into future so that customers have confidence that it will be able to meet its commitments to them" (2001, p36). Investors would learn from the balance sheet a company's long-term investments, capital structure, liquidity and gearing position so as to analyse if the company would be able to remain in business for a longer p eriod of time. The balance sheet at the end of the year demonstrates the total assets and liabilities made by the company. There are two types of assets; current assets and fixed assets. Current assets include all the assets that are for less than one year i.e. cash, accounts receivable (with deduction of bad debts expenses), notes receivable, prepaid expenses incurred and merchandise inventory where as fixed assets include all those fixed assets which can transcend for more than one year i.e. machinery, equipment, land, building and plant assets etc. The depreciation and amortization are deducted from these fixed assets. Liabilities are also of two types; current liabilities and non current liabilities. Current liabilities include debt which is payable in year i.e. accounts payable, notes payable, accrued expenses and insurance premium etc while long term liabilities includes bonds payable etc. These are not enough because for a complete balance sheet it also includes owner's equity which include s total invested capital and retained earnings. The balance sheet is not only essential for the investors but also to large extent to the company itself. It gives the financial conditions of a company that where it stands at a particular time and show the real minus and plus points. In order to get the things on credit or need some credit to invest in the business to earn amplify potential gains, balance sheet items i.e. powerful fixed and current assets would help in getting the credit (Birts, 2001). With the help of balance sheet it becomes easier for a company to make decisions and prepare the plans for future and it can also know about the reason of being unsuccessful in the business, it further gives a complete outlook of the company progress which helps a company to get rid of barriers and obstacles in the way of

Islam in Kyrgyzstan Term Paper Example | Topics and Well Written Essays - 2250 words
Islam in Kyrgyzstan - Term Paper Example This paper will analyze Islam in Kyrgyzstan and present an objective account of the role that this religion plays in this country. In order to do so, the paper will provide a general overview of the religion in question in the country and examine the process of introduction of it. Next, it will analyze the extent of influence of tribal religious system of the contemporary Islam as it is practiced in Kyrgyzstan, paying particular attention to tengriism, elements of shamanism as well as the peculiarities of their coexistence with the Muslim faith. The following aspect of investigation is the relationship between Islam and the state, namely the way the former influences rhetoric of certain politicians as well as legal system of the country. Finally, the paper will analyze the current status of Islam in Kyrgyzstan, including the increase in the number of mosques, introduction of Islamic banking and national holidays. Kyrgyzstan is a rather peculiar country. It is situation in the Central Asian region is border with such influential countries as China and Kazakhstan. It was a part of the Soviet Union and, therefore, was able to experience influence of communistic atheism on its religious life. In spite of the fact that Kyrgyzstan does not play a key role in the politics of the religion or its cultural life, this is a country that should be taken into account when it comes to understanding the diversity of the part of the world in question. It would not be a mistake to suggest that Islam was introduced to these lands relatively late: in the tenth century the southern part of the modern Kyrgyzstan was converted into Sunni Islam. However, the process of consolidation of tribes and their unification was slow: even today there is a big different between the southern and the northern parts of Kyrgyzstan. The people of this country were closely connected to their traditional beliefs; that is why to a certain extent such

Accounting for Planning and Control Essay Example | Topics and Well Written Essays - 750 words - 1
Accounting for Planning and Control - Essay Example In making investment decisions, various factors must be considered. Managers have to know that the success of the business entirely depends on how best the investments are analyzed before they are undertaken. First, capital budgeting requires large capital outlay (Dugdale 16). Most of the capital budgeting decisions require a large proportion of business funds. It, thus, implies that failure to make proper investment decisions will lead to losses for the organization. Secondly, investment decisions are irreversible. After deciding on what projects to invest in, managers will lack the ability to reverse their decisions, i.e., equipment once acquired cannot be easily disposed of. The managers must therefore be careful before settling on a particular investment projects because of this nature. Moreover, in analyzing investment, the future cash flows are of importance. The cash flows likely to arise to the organization after determining which projects to invest will be realized in the future. The cash flows cannot be determined with certainty and therefore depend on forecasts and future changes in conditions (Szpiro 53). Managers will use their skills in forecasting future cash flows and in evaluating the worth of the investments. Capital budgeting needs long time decisions and commitments. Various models are used in evaluating the investments to pursue by the organization. These can be largely categorized into two: non-discounted methods and discounted methods of capital budgeting. The non-discounted method include payback period in which the period required to recoup the capital invested is used. Projects with a short payback period are preferred. The return on investment is the second non-discounted method of project evaluation. In this method, projects with the highest returns are chosen for investment purposes. This method is pegged on the historical accounting estimates. The

Modern Methods of Construction (MMC) Benefits
Modern Methods of Construction (MMC) Benefits Drivers and Barriers of Modern Methods of Construction Work produced by; Blayse (2004), Goodier (2006), Koebel (2008), NHBC Foundation (2006), Pan (2006), Pasquire (2004), Rosenfeld (1994), Sexton (2005), Taylor (2009), The Barker Review, (2003), Venables (2004), The Market Transformation Programme (2008) and The Parliamentary Office of Science and Technology, (2003) have all suggested the necessity to increase the adoption of Modern Methods of Construction. These sources have stated the following perceived advantages associated with MMCs Tackling the skills shortage. An easier method of compliance to building standards. The ability to achieve high standards, including high thermal and acoustic performance. A reduction in waste materials, with a larger incentive for suppliers to reduce waste. Shorter build times. A better quality construction in finish with fewer defects. A reduction in both accidents and health concerns. Construction that is less effected by inclement weather during the build. Less local disruption in the form of noise dust and site traffic. Fewer and less skilled triads required on site. Creation of employment in a fix location due to the permanence of the factory resulting in shorter distances for the workforce to travel and thus making workforce shortages easier to address. Reduced cost/increased cost certainty, not only due to decreased erection time and economics of scale, but also do to a reduction in preliminaries, site storage requirements and welfare facilities Improved traceability of components enabling improvements to maintenance regimes. Improved accuracy and tolerances, due to the use of jigs and templates in factory conditions Reduced life-cycle costs Increased accuracy on completion dates A more simplified procurement process Reductions in CO2 emissions. Increased on-site productivity Generally increased ââ¬Ëvalue of products Increased rate of housing supply Although not all MMC solutions offer all of these advantages, it is the opinion of the vast majority of the literature that they would have a beneficial impact on the UK construction industry, if increasingly adopted. The most significant of these drivers for an increased uptake of MMCs will be discussed in more detail in the latter part of this chapter. There are however, a number of potential barriers to increasing the adoption of these methods suggested by the sources listed above. These include: Real or perceived additional cost and the lack of accurate cost data. Long lead-in times and the associated difficulties in integrating MMCs with traditional procurement systems. Clients negative perception. The lack of publish information and guidance. Increased risk and the industries reluctance to change. The lack of published codes and standards. The lack of local availability of the materials. The lack of experience of the construction process and the materials. Difficulties obtaining finance. Insufficient worker skill. Difficulties in achieving economics of scale. The fact that the quality and durability of the techniques over time have not been proven. Difficulties integrating MMCs with traditional works. The inflexibility of factories to respond to fluctuating demand. Similarly as with the drivers, not all MMCs are perceived to have these barriers to increased integration. Again, the most significant barriers will be discussed in more detail in the latter part of this chapter. As stated in Chapter 1, due to restrictions on time all of the above drivers and barriers and their significance to an increased adoption of MMCs cannot be discussed in detail. It is for this reason that the paper will now aim to establish the most significant issues for in depth discussion. Pan (2006) produced a survey of the top 100 private housebuilders (in 2004) by unit completion, to ascertain the most prolific drivers and barriers of MMCs in their opinion. As ââ¬Å"the top 100 house builders contributed 113,882 (65%) of the total amount (of new houses) by the industryâ⬠(Pan, 2006, p.185) in 2003, the level of use of MMCs within the sector will be largely determined by these companies. ââ¬Å"large housebuilders () account for the vast majority of housing completions and thus are determinant in increasing the take-up of MMC technologiesâ⬠(Pan, 2006, p.189) It is for this reason that the significance of the issues to these housebuilders will have a large effect on the adoption of MMCs within the housing sector. The work produced by Pan (2006), found that the top 3 advantages to MMCs from the opinion of housebuilders were addressing the skills shortage (61%), ensuring time certainty (54%) and ensuring cost certainty (54%). These results were followed closely by achieving high quality (50%) and minimising on-site duration (43%). Venables (2004, p.10) also found reductions in on-site assembly time as an important driver to MMCs adoption, but interestingly found that ââ¬Å"the quality of production and finish as the most significant advantagesâ⬠, in the opinion of suppliers. The same study by Pan (2006) found that the top 3 barriers to MMC from the opinion of housebuilders were higher capital cost (68%), difficulties in achieving economics of scale (43%), the inability to ââ¬Ëfreeze the design early on, and complex interfacing between systems, both at (29%). The nature of the UK planning system was also ranked relatively high by 25% of the respondents. Contrarily to this, work by Edge (2002, p.V) found that the major barrier to MMCs was the negative perception of the client. Suppliers were found by Goodier (2006, p.598) to have a similar opinion, with 65% of respondents viewing the negative image of MMCs as the major barrier to increased adoption of the methods. This demonstrates that the significance of the barriers to increasing the adoption of MMCs varies, depending on the position within the industry. Following investigation of the literature however, the overriding issues, which will now be discussed in detail, are: Addressing the skills shortage, ensuring cost certainty, improved quality, minimising onsite duration, high capital costs, difficulties in achieving economics of scale, and the perception of MMCs in and around the industry. Significance of Drivers and Barriers The negative annotations associated with modern methods of construction are an issue for the industry. Edge (2002) conducted a study to ascertain the causes for the resistance by clients and the market to prefabrication and standardisation in housing. Findings revealed that a large proportion of the resistance was within the housing industry itself. The commitment for change that was found within senior management was failing to defuse throughout the organisations enough to bring about the transformation. Interestingly the study found that the public was not resistant to new forms of construction entirely, although there was a partial resistance when considering the ââ¬Ëvalue of the new materials and methods. The study concluded that house buyers are strongly influenced by the negative association of the post-war ââ¬Ëprefab and as a result of this will resist changes to what a ââ¬Ëtraditional house looks like. An example of this would be the adverse media coverage that was r eceived by timber framed houses. Edge (2002, p.I) explains that this adverse media coverage severely reduced the application of this method in England to nearly 0%, whereas in Scotland it constituted 65% of new houses in 2001. The findings of Edge (2002), it would seem, have not diminished over time. Goodier (2006, p.589) found that the negative image of MMCs are ââ¬Å"by far the greatest influence on the industrys ability to expandâ⬠. This sentiment, although not listed directly as a barrier by the housebuilders, was found by Pan (2006 p.118) to be the most significant area to tackle, in their opinion, to see increase adoption of MMCs. ââ¬Å"There exists significant prejudice against the take-up of MMC among housebuilders and in the wider context of housing supplyâ⬠. This negative view towards MMCs was also found by Edge (2002 p.I) ââ¬Å"lenders are reluctant to give mortgages on non-traditional construction, () valuers put lower values on it () and that planners delay the process of acquiring the necessary permissionsâ⬠. Edge (2002) attributes these problems to the fear of the unknown techniques and potential maintenance problems, due to MMCs unproven nature that was discussed earlier. This Negative opinion towards MMCs is likely to be having a negative effect on the adoption of the methods. To increase MMCs take-up there will need to be considerable measures taken to improve its image. These measures are discussed in more detail in chapter 4. The suggested ââ¬Ëimproved quality that is presented as a driver for an increased adoption of MMCs may also have an influence in changing peoples perceptions, although it would appear that the industry is aware of this advantage. Pan (2006, p.187) found that 50% of the top 100 housebuilders viewed the ability to achieve high quality as one of the top 3 drivers for MMCs. Goodier (2006, p.588) revealed similar findings, with 79% of clients and designers and 77% of contractors viewing increased quality as an advantage of MMCs. Venables (2004, p.30) found that 39% of manufacturers viewed quality as the most important advantage of MMCs. A reason for low adoption of MMCs, even though the improved quality is known as a major advantage may be due to the point raised earlier, that the commitment for change that was found within senior management was failing to defuse throughout the organisations enough to bring about the transformation. This is because the surveys that were carried out in both Goodier (2006) and Pan (2006) were answered by persons high up in the management structure and so the advantages and disadvantages of MMCs may in fact not actually be realised by the persons choosing and using the systems. There is a large amount of supporting literature that agrees that improved quality can be achieved with the use of MMCs. An example of this would be the Parliamentary Office of Science and Technology who state that ââ¬Å"MMC houses typically have fewer defects ()â⬠(2003, p.1). The improved quality of MMC can be seen as a major driver, especially when considering that ââ¬Å"traditional building practices often fall short in conforming to design specificationâ⬠(The Market Transformation Programme 2008, p.3). A reason behind the apparent lack of impact that this advantage is having on adoption of MMC was given by The Market Transformation Programme (2008, p.3), ââ¬Å"Changes in construction practice, such as the use of drylining instead of wet plaster and the internal walls being studwork instead of blockwork, may give the occupants the impression that houses are less solid or robust than they used to beâ⬠. This relates back to the negative perception of MMCs and the fear of the unknown that was mentioned earlier and show how it is having a much wider impact on the uptake of MMCs than was first suspected. Work produced by Pan (2006, p.189) however states that ââ¬Å"the end market has shown little interest in how a house is built () location and price are the two main determinants of which house to buy.â⬠It was argued that this is due to the housing shortage and that housebuilders themselves should reassess their attitudes towards MMCs. The quality of MMCs it was discussed by Taylor (2009, p.6) is greatly improved, in comparison to traditional methods. This was attributed to the controlled working conditions resulting in fully tested services and a better finish in an environment that inherently reduces risks of accidents and ill health among the workforce. The potential quality improvements that can be made with the use of MMCs will have a large impact on their take-up. This is because as quality and other advantages become more apparent within the industry, not only to the persons implementing the systems but everyone involved, than perceptions are likely to change resulting in an accelerated adoption of the methods. One of the largest incentives of an increase in the level of MMCs to be used in the UK is that of time and cost. ââ¬Å"The construction industry () should use more offsite and standardisation in order to () reduce cost and time,â⬠Goodier (2006, p.587). Similarly ââ¬Å"innovative systems which take less time to construct on-site can lead to savings on, e.g. site prelims and equipment hireâ⬠NHBC Foundation (2006, p.5). Goodier (2004, p.4) supports this stating that ââ¬Å"the belief that using off-site is more expensive when compared with traditional construction is clearly the main barrier to increased use of off-site in the UK.â⬠This proportion of the literature suggests that there are cost and time savings to be made by the use of MMCs along with the work by Pan (2006) who found that cost certainty was viewed as a driver for 54% of the respondents. Although there is a view within the industry of cost savings, Pasquire (2004, p.2) found that ââ¬Å"the use of off-site production, by many of those involved in the construction process, is poorly understood. Some view the approach as too expensive to justify its use ()â⬠. This point was heighten by Venables (2004, p.33) who states that ââ¬Å"the general view is that it (MMC) is currently more expensive.â⬠A study conducted by The National Audit Office (2005) had similar findings, ââ¬Å"Volumetric and hybrid methods were slightly more expensive (than traditional methods).â⬠Lusby-Taylor (2004) also revealed that ââ¬Å"projects would cost more than if traditionally builtâ⬠. The most recent sources show that there is around 7-10% increase in MMCS costs, compared to traditional methods (The Market Transformation Programme, 2008, p.5). Taylor (2009, p.7) interesting states that ââ¬Å"Tenders often take no account of the shorter delivery and erection times () Othe r savings are made in the reduction of preliminaries, reduced site storage requirements and welfare facilities.â⬠This implies that the knock on savings of MMCs are often not included in the tender price. This was a sentiment that was also the opinion of Goodier in 2006 (p. 588). ââ¬Å"Many projects are still judged purely on first or initial cost.â⬠These sources show that there is much confusion as to the true cost of MMCs and if savings are achievable. The Parliamentary Office of Science and Technology mention that accurate cost comparison is difficult as ââ¬Å"project financial information is financially confidentialâ⬠(2003, p.2) and that traditional masonry costs vary widely. The unclear cost information is quite significant in effecting the uptake of MMCs as if cost comparisons are unclear or inaccurate than there is likely to be a reluctance to move away from familiar traditional methods by actors within the industry. Gates (2004, p.2) suggests that MMCs have failed to deliver cost savings and that it is expensive because the industry is small. The fact that the industry is small is suspected to be a cause for the higher costs, ââ¬Å"Many MMC suppliers currently design their products around tradition housing types. This is seen as a market entry strategy since it allows developers to demonstrate that a house produced using MMC components can be indistinguishable from a traditionally built home. Redesigning houses to better suit the specific characteristics of the MMC product would certainly allow for a cost reduction,â⬠Venables (2004, p.33). This again points towards negative perception of MMCs and results in production of products aiming to look like a traditional construction. This means that improved quality and cost reductions could be achievable without the need for the products to be disguised as traditional construction. It was the opinion of The National Audit Office 2005 however th at the cost of building elements could be reduced by 15% as the MMC market matures. This is encouraging for the MMC market as a definite cost saving could result in an accelerated uptake of the methods (The Market Transformation Programme, 2008, p.3). Work produced by Goodier (2006, p.588) indicates that this may be the case with 67% of clients and designers, and 77% of contractors viewing the higher expense of MMCs as the main barrier. Whilst it is unclear as to the true cost of MMCs in comparison to traditional methods in practice, a number of studies have shown that the higher capital costs are a major issue for the industry. Pan (2006) found it to be the most significant barrier to MMCs in the opinion of the top 100 housebuilders with 68% of the respondents. This may be due to the supply chain of traditional building practices, where there is more of a uniform expenditure throughout the duration of the project. With a number of MMC techniques there is a large expenditure at the beginning of the project, for example when commissioning the construction of a large number of volumetric units, which can cause problems to the cash flows of many projects. Interestingly however, the study conducted by Goodier (2006, p588) found that reduce initial cost was in the opinion, of 44% of clients and designers, and 15% of contractors, to be an advantage of MMCs. This difference of opinion could be attributed to the vastly diff erent methods that constitute an MMC and varying project delivery methods that are used within the industry which result in lower capital costs then with the traditional equivalent. The opinions of the top 100 housebuilders show that measures are required to combat the issue of high capital costs, however it should be noted that Goodier (2006, p.590) found that only 25% of suppliers thought that a reduction costs would overcome the resistance to MMCs. It is for this reason that possible solutions are likely to include promoting the other advantages of MMCs to ensure that tenders are based on value as appose to cost. This will be discussed in more depth in chapter 4. 87% of clients and designers, and 92% or contractors in the survey conducted by Goodier (2006, p.588) found decreased construction time as the main advantage to MMCs. The study conducted by Pan (2006, p.187) found minimizing onsite duration as the 4th most important driver for increased adoption of MMC. This shows that there is a clear benefit to using MMCs with regard to construction time onsite from the industry view point. This is because much of the work can be performed in factory conditions before work is needed to take place on site. This lessens the chance of accidents and defects, and reduces reliance on clement weather. As a knock on effect there is a reduced cost of rectification of defects, equipment hire, dangerous working conditions and delays. Taylor (2009, p.7) An example of reduced time on site of a project was given by The Office Of the Deputy Prime Minister (2003, p.1) ââ¬Å"the time on sight to complete () the project was 50 weeks, saving some 40 per cent compared with traditional site-based constructionâ⬠. Venables (2004, p.33) however, makes an interesting point in that ââ¬Å"while the actual on site assembly time for many off site manufactured components is significantly less than traditional components, the design and production lead in times, and in particular redesign times, can remove this time advantageâ⬠This point demonstrates that a major drawback of some forms of MMC, particularly those performed offsite, is the amount of pre construction work that is required in comparison to traditional methods. This point was found by Goodier (2006, p.588) as the 2nd most important barrier to an increased adoption of MMCs, with 46% of clients and designers, and 62% of contractors. Other associated problems inherent with these forms of MMC can be defects. As it has been established, MMCS generally result in fewer defects and improved quality, however when they occur, particularly in mass produced items such as a bathroom pod, the defects are likely to be present in all of the products. This is due to the repetitive nature of the construction, as opposed to traditional construction where a defect in the roof construction of a house is likely to be due to poor workmanship and expected to be present in only one roof. (The Market Transformation Programme, 2008, p.2) Venables (2004, p.33) states that if standard components can be used in a creative way to create variation in designs, whilst minimising alterations in the production lines, it will allow for the best advantages of economics of scales to be had. It should be reiterated however that Goodier (2007, p.590), found that only around 25% of the suppliers in the survey viewed a reduction in price as a means of overcoming resistance to modern methods of construction. This was in spite of the fact that it was viewed as the main barrier to MMCs adoption in the study conducted by Pan (2006). Goodier (2007, p.590) concluded that this was possibly due to the other appeals of MMCs, and so were basing their opinion on value as opposed to cost. Pan (2006, p.192) suggested that not all MMCs are applicable in all circumstances, however certain instances allow for significant gains to be had via economics of scale. By mass producing products there can be a number of benefits that result in quite substantial savings, however due to the specific instances that are required for this to take place the impact of this issue on further adoption of MMCs, as a hole, is likely to be minimal. A large proportion of the literature has expressed that a shortage of a skilled workforce as a barrier to MMC adoption. The Parliamentary Office of Science and Technology (2003, p.3) found that in 2003, 80% of housebuilders reported difficulties with recruitment. The skills shortage it would appear does not only exist within contractors on site but also at factories where a large proportion of MMCs are constructed. 11% of the respondents in the study conducted by Pan (2006, p.188) viewed the skills shortage as a barrier to MMC use. The study conducted by Goodier (2006, p.588) found that insufficient worker skill was an issue for 21% of clients and designers and 23% of contractors. This low rating by those within the industry may be due to the point raised by The Parliamentary Office of Science and Technology (2003, p.3), who argued that ââ¬Å"using MMC to build house parts in factories, and faster on site construction, means that fewer labourers are required.â⬠This would sugge st that increasing the adoption of MMCs is likely to decrease the problems found by housebuilders with recruitment. Goodier (2006, p.592) expressed that between 70% and 80% of the workforce within UK construction has no formal qualification, with a narrow skill base and limited training. The study found that the skills most lacking were Electricians, Joiners and Brick layers in the opinions of suppliers, designers and clients, and contractors. Goodier (2006, p.588) concluded that this is a driver for an increased application of MMCs, due to their findings that most within the industry viewed MMCs as requiring an equally or less skilled workforce. Contrary to this Clarke (2002) argues that ââ¬Å"a skilled workforce is required to enable innovation () to be appliedâ⬠and that due to the lack of broad basic training in construction after which they specialise, workers are usually trained for one role. This makes it difficult for the workforce to become multi skilled which is required for increasing the adoption of MMCs. Venables (2004, p.38) indicated that suppliers usually had to provide addit ional training as 89% of the general Labour available did not possess the multiple skills required. This was because suppliers normally require ââ¬Å"semi-skilled and multi-skilled workers with a medium level of training, rather than specific tradesâ⬠, (p.593). Taylor (2009, p.7) puts forward the idea that increasing the adoption of MMCs will reduce the impact of a skills shortage as permanently based factory units allow for the numbers and levels of skill to be more easily addressed than on static sites. It is also suggested that due to the lack of locally available skilled labour, the workforce will have to travel large distances with traditional construction, where as with offsite methods the workforce can be more centrally based increasing local employment. This shows that the skills shortage in some instances is acting as a driver of MMC adoption but at the same time may actually be limiting its take-up. A lack of skill on site may drive for an increased use of prefabricated components that require less skill to construct (Goodier, 2006, p.588), but if suppliers and manufactures of the products cannot obtain the skills required to build the components than MMC adoption is likely to fall. Chapter 4 will discuss the potential solutions suggested within the literature for coping with a shortage of skill in the workforce. Summary The discussion so far has established that there are a number of potential barriers and drivers to the industry if attempting to increase the adoption of MMCs. Major barriers have been determined and include: the negative public perception, the perceived or actual higher cost, the perceived or actual higher initial cost and the shortage of skills. The major drivers were also determined, these include, improved quality, reduced onsite duration and, again, the shortage of skills. Although advantageous to the industry it was discussed that they also have their own associated drawbacks.

Salbutamol Resistance
The maximum effect can take place within five to fifteen minutes. The other routes are orally (via tablets) and intravenously. Salomon has a number of medical uses, but It is mainly used to treat asthma and exercise Induced bronchus's. Treatment of chronic obstructive pulmonary disease Is another key use of this drug (diseases In this category Include chronic bronchitis and emphysema). Other less widely applied uses is in treatment of premature labor in obstetrics since the drug can also relax uterine smooth muscles intravenous administration) and in the treatment of cystic fibrosis in combination with other drugs (3).Despite ten Tact Tanat tens Aragua NAS Eden Invaluable In ten treatment AT serious medical conditions like asthma, there is still a serious pitfall in the long-term use of the drug since most people who have been on it for a long duration tend to the develop some form of drug resistance/tolerance to the drug. This results in a slower and less dynamic effect of the drug on patients who have been using it chronically. Therefore, directly translating to the need to adjust dose and frequency of the drug administration, this can become quite a burden to everyone involved.Down regulation of the ;2-receptors and a reduction of their sensitivity (desensitizing) causes this resistance (4). The drug has an intricate mode of action that involves a number of pathways at microscopic cell level. Initially, it acts by binding on beta adrenaline receptors (4). The receptor is coupled to a stimulatory guanine nucleotide-binding protein (as ââ¬â protein) and usually fluctuates between different conformations in the inactive state (5). Once the agonies (Salomon) binds to the receptor, it stabilizes one of the information leading to the activation of the G-protein.The G-protein is a transmigrate signal transducer that has alpha and beta-gamma subunits (6). After activation of the protein the alpha subunit dissociates, resulting in a form that stimulates activity of the enzyme densely cycles (7). This enzyme now increases the production of cyclic adenosine Mephistopheles (CAMP) in the cell. It does this by transforming adenosine troposphere (TAP) into CAMP through depopulation's and structure shifting (8). Increased levels of CAMP results in activation of CAMP- dependent protein kinas A.Protein kingies are enzymes that modify proteins by adding to them a phosphate group(usually derived from TAP). This phosphorescently leads to a functional change in the targeted protein either by altering the enzyme activity, its intracellular location or its interaction with other proteins (9). Protein kinas A is a CAMP dependent kinas and in the activated form, it works in two ways (all of which leads to relaxation of a smooth muscle); first, it decreases the acting- myosin interactions by phosphorescently the myosin light chain (10). Secondly, it lowers intracellular calcium concentration in the smooth muscle cells.This reduction comes about via two well researched and understood mechanisms. The first mechanism involves the regulation of influx and efflux of calcium through the calcium channels in the sarcoma (which is the cell wall). Protein kinas A causes the channels to increase the efflux of calcium from the cell and decreases influx (11). The second mechanism involves the ceroplastic reticulum which is the chief store of calcium in the cell. The kinas stimulates uptake of calcium into the store, therefore, reducing its overall concentration in the cytoplasm (12).The effect of these woo mechanisms (low calcium) leads to smooth muscle relaxation. Lastly, research shows that raised levels of CAMP causes a cessation of the release of mediators of inflammation from mast cells in the respiratory tract (13). All of these elaborate actions give Salomon its potency in dilating constricted airways and reducing obstruction secondary to inflammatory processes. But prolonged use and exposure to this drug leads to development of a resistance to it. Many schools of thought have come up with possible explanations as to now tens napes rater years AT Intense research.However, ten most accepted explanation is down regulation of the ;2-receptors and desensitizing of the same (14). It is now universally accepted that a cell's surface expression of this receptor and its coupling to signaling pathways inside the cell shows a negative feedback loop that works to reduce the cell responsiveness to prolonged occupation of the receptor by agonies lagan's. When an agonies attaches to the receptor, the stabilization involves phosphorescently (15). This usually interferes with how the receptor couples with the Gas-protein; therefore, limiting its function in what is commonly referred to as desensitizing.Desensitizing thus leads to reduction in the activation of intracellular signaling pathways secondary to prolonged receptor stimulation (16). This mechanism of uncoupling is rapid and reversible in nature, usually seen after short-term exposure. Phosphorescently of the receptor usually happens due to protein kinas A dependent pathways or by activation of G-protein receptor kingies named beta -ARKS (17). Tissues of different types show different degrees of this uncoupling when exposed to stimulatory lagan's, and this can be due to the differences in activity of the above mentioned phosphorescently mechanism.Apart from desensitizing another key process leading to Salomon resistance is the receptor down regulation. When ;2-receptors stimulation occurs for prolonged duration, they show a negative feedback mechanism that reduces their quantity of expression on the cell surface (18). The mechanism behind this is not particularly clear, but it is strongly believed to be due to receptor trafficking to lissome for destruction. Research has shown that chronic exposure to Salomon does not only lead to uncoupling but also receptor initialization from the cell surface.Initialization occurs through the process indications, whic h happens via Claritin coated pit endoscope pathway that works by forming buds from the cell membrane (19). When this process begins, Claritin (which is a small intracellular protein) begins to arrange on the inner surface of the cell's plasma membrane below the soon to be internalized receptor. The linear ends then start coming together to form a circular Claritin coated pit that has now engulfed a part of the plasma membrane, the receptor and some extracurricular fluid (20).The pit buds off into the cell and the ends of the plasma membrane come together to correct the deficit left on the surface. This pit is now referred to as a vesicle, and it traffics contents to a cell organelle known as a lissome (21). This organelle has an acidic environment and a number of enzymes that breakdown fats, proteins and carbohydrates. The vesicle fusses with the organelle's membrane and regurgitates its contents leaving the Claritin molecules on the surface (22). The receptor and other contents ar e consequently degraded. This is not the only aspect of down regulation that plays a part in reducing receptor expression.Research has shown that ;2-receptor Mrs. levels significantly reduce in the nucleus when levels of protein kinas A become elevated for long durations (days to months). Clinical features Clinical features of Salomon resistance occur when patients are intolerant to the drug therapy. Recovery, after therapy, is prolonged or absent even after maximum amelioration AT receive dose. I en most gallants clinical Torture appears in the deterioration of asthma and the subsequent exacerbation of the symptoms. Drug resistant asthma presents with (23); Worsening dyspepsia. Continuous wheezing and breathlessness. Chest tightness.These patients have developed tolerance to Salomon, therefore, are resistant to the therapy. With subsequent increase in the dose therapy which is not effective, patients with theoretically hyper-responsiveness with or without exposure to allergens and with the resulting inflammatory changes and bronchi-constriction, asthma worsens. The most severe clinical feature can present like status asthmatics or acute severe asthma. This present as episodes of severe asthma, failing to respond to usual effective doses of Salomon (24). There is progressive respiratory failure even within the course of therapy.This episode can progress to fatal asthma. Patients present with; Significant wheezing and dyspepsia. Severe respiratory distress. Hyperventilation and subsequent respiratory leukemia. Features of metabolic acidosis due to anaerobic respiration and elevated levels of lactate from the respiratory muscles (25). Severe asthma will occur with increasing degree of hyper-reactivity due to intolerance to drug therapy: ineffective relief and loss of bronchitis tone. Clinical feature can also occur as a result of high drug dosage. Resistance causes a patient who is in respiratory distress to use increasing and more frequent doses of albums.High doses produce toxicities which can present with systemic features (26). In the respiratory system; there can be hyperemia. Salomon is a psychosomatic agent (beta 2 agonies) the vacillators effect of beta 2 Zionists increases perfusion of poorly ventilated lung units, transiently decreasing arterial oxygen tension (27). Significance of this effect depends on initial partial pressure of oxygen of the patient. Hyperemia will present clinically as occasions, respiratory distress, and tachyons. There can be paradoxical bronchus's due to the Atonally antagonism to Transcendentalist erect AT SalomonI en spasms, AT the smooth muscles lining the bronchi, are due to psychosomatic action of Salomon and adrenaline stimulation. In the cardiovascular system, the psychosomatic action of Salomon can cause toxicity which might result in cardiac arrhythmias, arterial fibrillation, supercritical tachycardia and extra systole (29). There can be an occurrence of coronary insufficiency due to hyperemia, atheistically and resulting tachycardia, peripheral bastardization with a compensatory small increase in heart rate, hypertension and palpitation. In the endocrine and metabolic system, there can be hypoglycemia.Salomon may stimulate sodium and potassium Tapes which causes redistribution of electrolytes (30). Hyperglycemia in a diabetic patient; Salomon stimulates the beta 2 transporters which stimulate hepatic glycogen breakdown for pancreatic release of clangor which increase plasma glucose. In the central nervous system, overdose of Salomon therapy intolerance can produce CONS symptoms such as insomnia, weakness, dizziness, nervousness, tremors, transient muscle cramps and headache. Rarely reported effects include drowsiness, irritability, chest discomfort and difficulty in instruction (31).Diagnosis Diagnosis of Salomon resistance follows the clinical guidelines of a full comprehensive history of the patient, physical exam, and investigation to confirm the patient's tolerance to drugs. In taking the history certain question might lead to the discovery that a patient previously on Salomon therapy is unresponsive to the drug. When doing a physical exam, clinician should check out for general observation such as respiratory distress and occasions. In doing a systemic exam, focusing on the respiratory system may bring out worsening respiratory function.Clinician may find wheezing with other signs indicative of exacerbated asthma. Investigation Investigative studies are confirmatory and supportive to the diagnosis. The base lines include; Full blood count. Urea electrolyte count. Liver function tests. Random blood sugar if suspecting diabetes. I en consoler long toner tests In prospector s o mol toxicity al u TA Pulmonary function tests Serum blood gas analysis with pH profile Cardiograms to check arrhythmias Gene typing; the cornerstone of Salomon resistance detection is gene typing. Experimental studies have shown that tolerance in asthma is in the polymorphi sm of he DRAB gene.Analysis show that tolerance is in the glycogen allele at position 16 and 21 at the beta receptor gene. Gene typing for polymorphism can aid in identifying patients with drug resistant asthma (32). Management Management can be categorized as supportive, specific, preventive and rehabilitative. Supportive management include; Outpatient monitoring if not severe Admission to a hospital if severe. Severe asthma necessitates immediate admission as it can be fatal. Oxygen therapy. Intubations and mechanical ventilation if severe. Use of parental corticosteroids which are anti-inflammatory.Fluid and electrolyte resuscitation in the case of hypoglycemia. Frequent monitoring of patients to the drug. Specific management is both surgical and medical. Surgical management, research is still underway and ongoing. Medical management includes the use of a second-line therapy like monopolies, astatine and antihistamines. There is also use of cardiac-selective beta adrenaline block ing agents and corticosteroids in Salomon toxicity. Other drugs can be used depending on symptom's of resistance, for example; interventions, insulin and any other depending on the symptoms of the patient.Surgical intervention for example attempting bronchial thermoplastic. This is a bronchitis procedure in which delivered thermal energy to airways; it reduces airway smooth muscle hyper responsiveness. It has been also shown to be beneficial in treatment of severe asthma where continuous therapy has failed. Preventive management Includes gene typing early enough to Isolate patients wilt Salomon resistance by checking the beta AR gene. The other way is to prevent high-drug toxicity. Rehabilitative management of any complication that might occur is essential.
