Global and International Business Contexts Essay

Introduction This report has been written by the Boston Consulting Group and uses Porter’s national diamond analysis model to evaluate the attractiveness of investment opportunities in the Tunisian wine industry. Also discussed are two key management issues that need to be taken into account before developing operations in Tunisia followed by recommendations on two strategies for entry into the Tunisian wine industry market. In terms of background to this report, it should be noted that the global market for wine industry is changing significantly with substantial differences in the structure of the wine industry around the world. For instance, there are 232,900 wine producers in France but the top 10 brands control only 4% of the market. In contrast, four firms control over 75% of the Australian wine market. Hence there is a marked difference in industry structure when comparing the â€Å"New World† producers (e.g. Australia, Chile, United States) to the â€Å"Old World† fir ms. These structural differences are driven by institutional diversity and contrasting patterns of historical development in countries. However, they are also driven by the competitive strategies employed by particular firms which are determining factors discussed in Porter’s Diamond model. Porter’s diamond model allows an analysis of why some industries within nations are more competitive than others and takes into account the home base of a business (Tunisia) as one element that plays an important part in  successfully achieving competitive advantage in the global market. (See insert 1.1) Part 1: Porter’s National Diamond Analysis Porter’s national diamond analysis model has four main determinants, which are factor conditions, related and supporting industries, demand conditions as well as strategy, structure and rivalry. Factor Conditions Factor conditions are those factors that can be utilised by companies inherently found within a nation which might provide competitive advantage such as human resources, material resources, knowledge resources, capital resources and infrastructure. These factor conditions can be built upon by companies to improve their competitiveness. Factor conditions could be divided into two resources as home grown resources and highly specialised resources. As Michael Porter described, the home grown resources are important and in the case of Tunisia includes the natural resource of a climate well suited to wine growing, plenty of sunshine, fertile soil as well as limited pollution which all aid the industry of grape planting. Political and historical factors through Tunisia’s history such as the romans, French occupation which resulted in over 600 caves being created for wine aging and a recent flourish in the Tunisian wine industry after the 1980’s has left Tunisia with a number of cooperatives and engineers all with specialist skills in wine production where modern techniques are being used creating innovation, technical progress and competitive advantage. The relative low cost of employment and salary levels in Tunisia compared to European countries brings with it a further home grown Tunisian competitive advantage together with an increasingly skilled base of employees who have worked in the wine industry. (http://www.tunisieindustrie.nat) Salary Per hour rate In Tunisia: 48-hour workweek: 1.538 DT per hr – Equates to 53p (in British pounds) per hour 40-hour workweek: 1.584 DT (http://www.tunisieindustrie.nat) Demand Conditions This is the demand for products in the home market which can be influenced by three factors; the mix of customer’s needs, the scope of domestic demand and growth and how the needs of domestic market translate into the global market. Whilst the annual domestic wine consumption per person in Tunisia is only 8/9 litres compared to an average of 60 litres a year in France, a domestic wine industry is likely to encourage greater levels of demand at  home from loyal customers to increasing levels of tourists (Ariaoui, 2007). Also consumer attitudes and behaviour play a role in domestic wine consumption because wine plays a very different role in European culture as compared to American, Australian culture or even Tunisian culture. In Europe wine remains part of everyday life and consumers often drink it along with the daily meal. Financial incentives offered by the Tunisian authorities have further helped to support the domestic wine industry making it more attractive to foreign i nvestors. As in new world producers, these investments in the Tunisian wine industry have helped encourage innovation enabling Tunisian wine growers to enhance the consistency and the quality of their wines by reducing operating costs through the increasing use of machinery to harvest the grapes crops. Tunisia can also learn from the New World which has more extensive and well-developed markets for its grapes, making it easier for wineries to find multiple avenues for sourcing production. Related and Supporting Industries At present, Tunisia make wines ranging from average to high levels of quality and they export their products to the whole world including famous brand names such as Carignan, Mourvà ¨dre and Muscat of Alexandria. The Tunisia government has supported their domestic wine industry through the construction of railways and roads (national infrastructure) to enhance the innovation and technological development in wine making which in turn is benefiting other related and supporting industries such as transport, holiday and leisure industry, technology and machinery. Taxes at 18% on wine consumption in Tunisia also provide an important income for the Tunisian treasury and so restrictions are unlikely in the future as in such nations as the US, Chile, and South Africa and should ensure continued support from the Tunisian government. Firm Strategy, Structure, and Rivalry The structure and management systems of firms in different countries can potentially affe ct competitiveness and how well a company is able to use its existing organisational structure whether it is hierarchal or flat, against current and potential competitive companies. It is very important that the Tunisian wine industry pays close attention to its industry and company structures and strategies to ensure it is suitable for expansion into the global market. Porter argues that domestic rivalry which involves company structures and the need to pursue competitive within a country like Tunisia  could help provide the wine industry with a basis for achieving global leadership. Structural differences including institutional differences in wine production countries vary considerably and are often influenced by regulatory agencies such as in France, for instance which employs very strict regulations that constrain production so that producers can only designate sparkling wine as â€Å"Champagne† if they produce it using three grape varieties grown in the region with the same name unlike Australia which has a very loose regulatory structure allowing winemakers to source grapes from diverse geographic regions within the country. Different levels of subsidies have led to structural differences globally in wine making such as European governments who often subsidise their small farmers who grow grapes whereas subsidies tend to be lower or nonexistent in most New World nations. In addition, capital markets and corporate ownership patterns differ between geographic regions where typically Europe tends to have many more privately held firms in contrast to most of the largest winemakers in the United States and Australia who have become publicly traded corporations. Land ownership and historical patterns of development represent another major factor explaining the structural differences between global wine production areas. For example in the Old World, winemaking has been organised around family farms for centuries. and the land has remained in family ownership for generations. However currently, Tunisian landowners appear to be able to exert power in particular locations where high-quality land is scarce. This appears to be a problem where most producers are small, and good new acreage in Tunisia is extremely scarce but it is worth noting that grapes now cover more than 10,000 hectares of land in Tunisia compared to around 100 hectares in 1889 and wine production ranks third in Tunisian agriculture just behind olive oil and wheat production (Ariaoui, 2007). Finally, the competitive strategies of firms can affect industry structure such as the United States and Australia where publicly traded firms are much more prevalent. These firms have altered the industry structure and competitive landscape through their acquisition strategies, consumer branding and advertising strategies, capital investment plans, and technology initiatives. Consolidation of the wine Industry began to increase over the past decade, particularly among the New World producers with the consolidation of some premium wineries merging with direct rivals such as Rosemount creating some major global producers.  In terms of industrial structure, Tunisia, as yet is a small but relatively high cost producer of wine in comparison but now successfully exports millions of litres of wine annually to Europe, Russia and the US with two thirds of its wine production being controlled by the UCCCV (Union Centrale des Coopà ©ratives Viticoles) and is looking for global partners to exploit and develop Tunisian wine production opportunities. Part 2: Contemporary Management issues Leadership Style It is undisputable that many of the global wine producing companies who used to dominate the market are now experiencing a decline in market share. There are several reasons that can be used to explain such a decline including leadership style. The appropriate leadership styles are those that can enable the manager to interact closely both with the employees and the customers and as a facilitator whose major role is to bring together and create an organisational culture that is streamlined a geared towards meeting the goals and mission of the organisation. If the Tunisian Wine Industry is keen to expand, its management team should know that leading others is not a simple task. As a people manager, a leader has to treat everyone as equal regardless of their title or position and maintain a pleasant demeanor (Ljungholm, 2014). It is about focusing on gaining trust and commitment rather than enforcing fear and compliance. To be able to lead well, leaders need to be guided by appropriate leadership theories. Some of the theories proposed include supportive leadership model and transformative leadership model. These models should enable the Tunisian wine industry to adapt new environment easily and are described below. Supportive leadership model Supportive leadership model, is where the manager supports every stakeholder emotionally and professionally in an attempt to ensure that he or she performs optimally. It also focuses in forging and creating collaborating and binding relationships among employees (Mahalinga Shiva, & Suar, 2012). The workplace is often made up of people from diverse backgrounds, with varying needs and wants and it calls for patience, understanding and proper leadership skills. The supportive model believes that influencing people to do something is more productive and sustainable than barking orders and instructions to people (Hutchinson &  Jackson, 2013). A leader should always keep in mind that as a manager, he or she has to â€Å"Treat everyone as equal regardless of their title or position and remember to smile a lot and always maintain a pleasant demeanor.â €  The leader should focus on gaining trust and commitment rather than fear and compliance (Hutchinson & Jackson, 2013). This cannot be achieved without deliberately motivating the people to become better. Motivating them requires that you first understand their training and development needs. The leader should learn to foster warm relationships amongst the Tunisian employees to understand them and identify ways in which interpersonal relationships can be improved for a more fulfilling work experience. Transformative leadership model The second most important model is transformational leadership theory or model. This is a new model that was formed in around 1970s following the realisation that there was need of greater flexibility in employment. The current employment conditions have changed significantly and this model is particularly relevant to the Tunisian wine industry which is relatively new as an industry (1980’s onwards) and because most of the Tunisians of employable age are from the millennial generation. One thing to note about this new generation is that it is educated and culturally more mixed than any generation before them. In the US this typically means they are job-hoppers who hate officialdom and mistrust traditional hierarchies (Goudreau, 2013). This group of employees, according to Forbes, is willing to sacrifice pay for increased vacation time and the ability to work outside the office. According to the study conducted by Forbes, one of the ways of motivating this generation is that they want employers who offer flexibility or rather alternative work arrangement. The transformational leadership is characterised by a lot of motivation as under this leadership model, the leader is expected to provide constructive feedback, encourage employees to exert effort and to think creatively about complex problems (Xueli, Lin & Mian, 2014). Transformational leadership is based on what is called lead, learn and grow model.. A leader can implement transformational leadership by keeping track of the impact of his action, engaging in formal evaluation at the right time (Abbasi, & Zamani-Miandashti, 2013). A leader must also be willing and able to learn on an ongoing basis and should realise that learning is never complete. That is why under transformational leadership, no one is an expert (Watts, &  Corrie, 2013). Unlike in most European wine producing areas the problem with most leaders there, is that they tend to believe that they are qualified or that they are expert, whereas in Tunisia producers are looking for expertise outside of the country and seem willing to learn. Tunisia wine production has an opportunity to analyse and create and take into account the appropriate leadership style for the wine industry and country that will be maximise competitive advantage before wine production operations can be developed in the country. Part 2: Continued Contemporary Management issues Knowledge and Change Management Rapid changes in business and technology and increasing competitions means organisations have to adapt the best training and education to enable them continue to stay on top of their games. The complexity, relative newness and competitiveness of the Tunisian wine industry environment requires that Tunisian companies will have to continuously raise the bar on their effectiveness to compete globally. Top performance increasingly demands excellence in all areas, including leadership, strategy, productivity, and adaptation to change, process improvement, and capability enhancement on knowledge, skills, abilities, and competencies, trust and motivation. An organisation in the wine industry should ensure that all levels of employees are given the opportunity to continue to improve by acquiring new skills through training. Much of the improvements needed in business to meet the demands of changing markets and economic conditions can only result from well-implemented organisational change measured against increased technological excellence and operational efficiency as well as productivity. Kotter (2011) defines change management as the utilisation of basic structures and tools to control any organizational change effort. Change management’s goal is to minimise the distractions and impacts of the change. Organisational change is incredibly complex and one of the key skills for managers is to understand the nature of change and to prepare themselves to lead and manage change in their unique organisational contexts. Where there is a lack of knowledge in the Tunisian wine business in terms of management strategies to deal with changing markets and economic conditions, Tunisia will need to look at their alliance business partners and those business  sectors in Tunisia that are successful in order to transfer and recruit the necessary management skills to succeed. Part 3: Market entry strategy – Strategy No 1 Formulating a mode of entry is very important factor that a company or industry intending to expand into a new market should bear in mind and predicts whether the company will turn out to be successful or not. The entry mode, according to International Business Publications (2009), is important in protecting the company from facing challenges such as legal, registration and even cultural challenges. In selecting the entry mode, the company should put into consideration the cost of doing business in destination country, and determine which entry mode will help in cutting down those costs and at the same time will ensure that the Tunisian wine industry gets maximum profits and also the largest market share in the target nation. In terms of advantages and based on the market situation, this paper proposes that the Tunisian Wine Industry should adopt cross-border strategic alliances to take advantage of a number of benefits compared with the export strategies. For example it creates different synergies in the domestic and foreign markets. In addition, it promotes production alliances, which help each of the allied firms to reduce production costs both in their domestic plants as well as their foreign plants. As far as distribution costs is concerned, the cross-border marketing, which is a product of cross-border strategic alliance, reduces the allied firms’ distribution costs in their foreign market (Qiu, 2006). Compared to other entry mode methods, cross-border strategic alliances create different synergies in the domestic and foreign markets (Qiu, 2006). Some of the synergies include production cost synergies and distribution costs synergies. These synergies will help the Tunisian wine industry to reduce the production and distribution costs and hence increase profits. In terms of disadvantages, cross-border strategic alliances can sometimes lead to a loss of control of individual wine production and their related services. Members of Tunisian wine production may well find that they can become restricted and unable to take decisions by themselves without first referring to the alliance partners. In addition, the complexity of making business alliances work is high and could further complicate business  structures, exacerbate cultural differences and have detrimental effects on intercompany working relationships. Part 3: Market entry strategy – Strategy No 2 Alternatively, the Tunisian Wine Industry may enter into new market through what is called licensing. Licensing mode of market entry allows foreign firms, either exclusively or non-exclusively to manufacture a licensed product in a certain market under specific condition and for this reason is particularly relevant to the situation faced by the Tunisian wine industry. A licensor in the home country makes limited rights or resources available to the licensee in the foreign country in which he or she is to do the business. This includes any resources may like patents, technology trademarks, managerial skills that can make it possible for the licensee to manufacture and sell in the foreign country a similar product to the one the licensor has already been producing and supplying in his home country. This enables the licensor to have several shares in similar companies without necessarily having to open a new branch in other countries. The licensor is usually paid on basis of one time payments, mechanical fees and royalty payments usually calculated as a percentage of sales resultant thereafter. The decision of making an international license agreement depend on the respect that foreign government show for intellectual property. The licensee should be able to cooperate with the licensor to avoid unhealthy completion in the market. In terms of advantages, licensing is a flexible agreement and can be adjusted any time to suit the conveniences of the both parties. However, this mode of entry can be disadvantageous to the licensee, as parts of the profits have to be shared to the licensor on these terms. Recovering the initial profit and getting reasonable profits can take a relatively longer period of time. Again it can also result in the loss of control over manufacturing and marketing of goods and export to other countries. A further risk to the Tunisian wine industry to take into account when considering this strat egy is that the foreign licensee may sell similar competitive wine products after the licensing agreement has expired. Recommendations To Board of Directors To conclude, when entering into a new market, there are many existing factors  to keep in mind. Porter’s national diamond model can help potential investors by allowing them to understand the macro environment in the Tunisian wine industry. Generally speaking, factor condition, demand condition, related and supporting industries and rivalry could encourage the entering activities. It is worth noting that the past high cost performance of Tunisian wine could also become a strong competitive advantage by restricting new entrants into the Tunisian wine producing market. As for recommendations, Tunisia offers the advantages of a natural wine producing climate and fertile soils, a relatively low cost of employment, significant financial incentives and investment in the countries’ infrastructure by the Tunisian government and unrestricted company structures and land ownership. The limitations of Tunisian wine industry relate to the relatively higher costs of wine production in Tunisia, increase in licensing opportunities across the wine industry and cross border alliances which can complicate international working relationships and introduce some uncertainty in the future as licensees from other countries continue to exploit Tunisian wine production opportunities resulting in possible delays in the release of profits available to international investing businesses.

Cash flow analysis

The company's cash flows from operating activities were inadequate to cover depreciation and dividend payments from FYI to IFFY. This indicates that HEAD Banks cash flow engine is not generating enough cash to keep the company whole for those three years. However, the company generated excess cash in IFFY, which was used for growth and investment purposes. Thus, the cash flow engine is not very powerful. However, it is showing signs of recovery in the recent years. Pinpointing the Good News and the Bad News The capital expenditure shows an increasing trend and is around 1 . Xx of appreciation.In addition, it made significant investment in subsidiaries and Joint-ventures, which is another growth indicators. However, these indicators have not remained consistent throughout. Such investments were only made in FYI 1 and IFFY. HEAD Bank has consistently borrowed from other banks in the form of term deposits and demand deposits to pay dividends and for capital expenditure. This can be cons idered as a bad news because it doesn't have sufficient cash flow from operating activities. Puzzle Since the company is operating in the Banking and Finance Industry, Reserve Bank ofIndia norms mandate that the company hold a large proportion of cash along with significant deposits with the RIB (CAR and SSL norms) in order to maintain liquidity. The cash and bank balances held by the company has ranged from xx to xx of their net income. Earlier, we identified a few unusual line items, which are explained as under: In IFFY, RIB increased policy rates by 1 . 75% and Rib's borrowings against SSL increased by almost 270%. After adjusting for this, cash flow from operating activities shows a positive figure in IFFY.In the cash flow from operating activities, the cash used in distributing loans & advances as well as making investments (operating activity since it is a bank) exceed the cash generated from increase in deposits. This has resulted in a negative cash flow from operating activ ities in 3 out of 5 years. This requires the company to seek outside sources for funding such as financial borrowings from other banks and financial institutions. This may not necessarily be a negative sign if the returns from operating activities exceed the net borrowing costs and hence reaping the benefits of leverage.

Lakeside Country Club tour report Essay Example | Topics and Well Written Essays - 500 words

Lakeside Country Club tour report - Essay Example The Mansion forms the central part of the clubhouse even today. The house had three stories with 8 spacious rooms that faced the lake that was built by Mr. Mooers. The lake is presently known as the Pine Lake. Mr. Mooers sold the property to Ralph Rupley in 1946. Rupley became a charter member of the club. Mr. Rupley and his family immediately occupied the mansion, which was known, as the Pine Lake Farm until 1951. Mr. Rupley moved to a more appropriate residence in the city in 1951 when the Lakeside Country Club signed its charter. This brings us to the date when the club was founded; 1951.In 1952, the club bought additional acreage. This was intended for the construction of the original locker room wing, trap ranges, bathhouse, swimming pools and tennis courts. The Lakeside club has a complete scale of operations with 73 golf carts, which offers the club high level of revenue. For instance, a half million dollars of the total revenue is generated from renting the golf carts. In addition, the available teaching programs add up to the revenue collection. Some of the teaching program available includes the junior gold, women’s program and individual group lessons. On equal measure, the fee charged on members on the carts usage also contributes to the club’s revenue basket. For the case of employees, the Lakeside Club has 24 full time employees. The working time during weekdays is 6.00-2.00 and 5.00-10.00 during weekends. The Club’s source of water is the Buffalo bayou. The club always endeavours in maintaining it grass root system and on the side of wildlife; the club’s management has ensured sustainable protection of diverse species for a health environment and nature. However, the club management cites maintainin g the golf course weather condition as the hardest challenge. For instance, when the Hurricane Ike came it destroyed the club with water almost a half way

Case Analysis.Corporate Sustainability Study Example | Topics and Well Written Essays - 1000 words

Analysis.Corporate Sustainability - Case Study Example Key issues and such as the melting of the polarized caps, global climate change, the impacts and facts of CO2 emissions, increased awareness for the impacts of oil and gas drilling, and a host of other factors all contribute to the increased awareness and concern that consumers are reflecting towards business with regards to sustainability issues. Within such a context, it is readily noted throughout the corporate sustainability piece in question that UPS has actively engaged in seeking to promote a further level of green business and sustainability at each and every stage of their corporate structure. All the way from maximizing efficiency by utilizing advanced computer programs and metrics to plan and pack each and every plane or product that carries packages for the efficiency to utilizing LPG as a low impact/low CO2 fuel for the transit of packages and many other factors, the firm has shown a clear and definitive concern both for the demands of the consumer and the future prospec ts of the environment. KPI: relevance and use as indicators Key performance indicators are a means by which UPS can seek to track whether or not it is been successful over the past several years with regards to the key determinants of efficiency and other metrics that it has defined. Within such an understanding, UPS has defined these KPI as the following: water consumption, energy consumption, gallons of fuel per ground package, aircraft emissions per payload capacity, CO2 emissions, number of reportable spills, aviation gallons burned per 100 available time miles, CO2 pounds per available time miles, total charitable contributions, full-time employee retention rate, employee choice index, injury rate, and lost time injuries (Santiago, 2011). Within such an understanding, it can be concluded that these KPI’s are the ultimate metrics by which UPS seeks to measure itself with regards to how it has improved over the past several years and where it seeks to take the development of the firm in the very near future. Benefits of utilizing and leveraging a sustainability report Although there are many benefits that can be definitively realized as a result of the creation and analysis of a corporate sustainability report, such as the one which is been analyzed within this brief essay, the two most important benefits that such a report can provide our with respects to the internal and external benefits that can be garnered. With regards to the external benefits, the delineation and discussion of metrics, KPI’s, and other determinants are useful in encouraging shareholders of the firm to have a degree of faith that the entity is fully cognizant of the realities of the current market and is actively working to provide resolution to some of the key challenges and/or problems/opportunities that face it within the next several years (Soupata, 2011). Similarly, the benefits can also be understood with regards to the internal ramifications that such a summary ca n have. Whereas it is not unnatural for the higher of salons of corporate management to come up with reports such as the one which has been analyzed herein, it is something of an anomaly when such reports are engaged by middle management and sought to be promoted at all levels throughout the

Language and Power 2.2 - Essay Example As such, the following analysis will seek to provide an overview and understanding of how educators, as well as fellow stakeholders, can develop effective responses to issues of language in power. It is the hope of this particular author that such a level of discussion will be beneficial; not only in providing a broader level of identification and understanding of the subject matter of module two – but also in terms of effectively understanding the many nuanced impacts that language has upon the life of the individual student and stakeholder within society. Similarly, a specific focus will also be placed upon pedagogical responses to my: such as critical literacy, critical pedagogy, critical multiculturalism, and other aspects that are oftentimes included in core curricula around the globe. In terms of critical pedagogy and critical multiculturalism, Alastair Pennycook indicates that one of the major issues facing educators within the current era has to do with the interpretation of teaching ESL students; or more specifically (Teaching English to Speakers of Other Languages (TESOL). Within his article, entitled â€Å"Critical Moments in TESOL Praxicum†, Pennycook indicates there is a certain stigma that is attached to teaching these students; a stigma that most directly relates to an understanding that TESOL education is a type of grunt work – something that no other educator wants. As can directly be seen, the implication of this has for critical pedagogy and critical multiculturalism is one in which these students are oftentimes understood or viewed in terms of the â€Å"untouchables† (Pennycook, 2004). Whereas it is oftentimes not the race, gender, or culture of the ESL student that encourages certain educators to make this assessment, the impac t of lack of desire, lack of passion, or lack of interest in

Environmental Effects Statement for the proposed (Persistent Organic Research Proposal

Environmental Effects Statement for the proposed (Persistent Organic Compounds) storage and treatment facility - Research Proposal Example This article’s main aim is tooutline a few things such as how the development is likely to impact on the environment; ways in which the impacts could be identified and measures that would be put in place to mitigate the social and economic impacts of the project on the environment.Within the SEE, a suitable location for the development of the project should be suggested and details outlined. Background The development plan featured here is the setting up of POP (Persistent Organic Compound) storage and treatment facility is which is to be built near Mortlake, Victoria. The purpose of building this facility is to dispose Australia’s 500,000 tonne stockpile of organ chlorines such as DDT, Dieldrin and Endrin, polychlorinated biphenyls, hexachlorobenzene, dioxins and furans. The company that has proposed the storage and treatment facility received information that they will have to go through the environmental effect process before approval could be given for this project. With the support of both the State and Federal Governments the process will be heard under Victoria’s Environmental Effects Act (1978) and the Federal Environment Protection and Biodiversity Conservation Act (1999). Body The Queensland Environmental act protection act 1994 is a statute that provides legislations, standard procedures, codes and control approvals when setting up projects so as to monitor and manage operations on site. Given the size of the project, a lot of organisation should be done and clear-cut strategies be put in place. Some of the things the project managers should outline include how to relocate or compensate owners of the 1000 acres of land where the project is going to be built and the cost implications it will have on the stakeholders of the project. Operations involved and the estimated period of time required for setting up the project is also vital. Scrutiny of the site should also be done to verify whether there are any hindrances to the project such as underlying mining tenements. The numbers of people required to provide labour should outlined (BERTRAM, 2005, p201). There are a number of implications; either social or economic, that could arise as a result of setting up the project. For instance, looking at the topography of the land, excavators will have to dig deeper into the ground which could result in for example release of air emissions from underneath that may be hazardous to humans. It is important that both personnel working on the site and other nearby residents be informed on such dangers and protective clothing be distributed so as to mitigate the effects such dangerous chemicals could have on individuals. The dug up soil could also contain dangerous chemicals leading to contamination and it is recommended that it is disposed in the right manner. The proposed construction for all temporary landforms is also likely to cause possible erosion as the area is cleared of vegetation. Clearing or demolishing of the h ouses within the site may likely lead to stockpiles and limit access to certain pathways. In the wake of the construction, it is also likely that some parts of the neighboring land’s fertility or productivity be constrained.â€Å"JOUMARD, p34,† argues that in order to ensure that the land remain fertile or at least a little productive, the

Process and Change Managment - Research Paper Example This continuous change has affected the relationship status of people with places, things, ideas, organization and other people. These changes require new adaptability level for organizations and individuals. 2.2 Business process reengineering In the current business environment, global organizations are going through a change which is continuous and rapid. Increasingly driven by competition, consumers and change, companies are vigorously trying new ways in order to make their business and organizations more competitive and effective. Companies are evaluating and analyzing their current structures, goals and systems in order to find out new and more efficient solutions to their business issues. A new era came into existence, when high profile organizations such as Taco Bell and IBM came up with an extraordinary solution to improve their present condition. This solution was business process reengineering. This solution then became a rage and was followed by many others such as Hallmar k which totally re-engineered its process of new-product development and Kodak, who went on to reengineer its black and white process of film manufacturing (Hindle, 2008). BPR was regarded a novel approach for organizational and corporate change and since then, it is quite popular. During the early 19th century, the concept of reengineering was first developed. After examining the way information technology affected the business process, it was renamed as business process reengineering (Sturdy, 2010). BPR was then described as radical redesign and fundamental rethinking of business process with the objective of achieving dramatic improvements in contemporary and critical performance measures such as quality, cost, speed and service. 2.3 Challenges... This paper approves that in the current business environment, global organizations are going through a change which is continuous and rapid. Increasingly driven by competition, consumers and change, companies are vigorously trying new ways in order to make their business and organizations more competitive and effective. Companies are evaluating and analyzing their current structures, goals and systems in order to find out new and more efficient solutions to their business issues. Even though BPR has been recognized for its effective and quick recovery strategies, there are many challenges during its implementations. This essay makes a conclusion that In the current study, one of the most recognized concepts â€Å"Business Process Reengineering (BPR) has been evaluated as a tool for change management. BPR has been recognized as an effective approach to management which is applied and adopted widely by organizations for successful and effective results. Support and commitment are important factors for success in BPR projects. Support of top management in terms of resources, capital and leadership for project life is essential which otherwise will weaken the projects and its success chances. Proper communication and teamwork are also vital for successful BPR applications. Apart from the above factors a BPR project will be successful if it is conducted according to the overall strategy of the organization. If the company strategy and BPR projects do not complement each other, the business will only achieve gains which are short term and will lose chances of long term improvements in performance.

The Impact of the Employee Handbook on Organizations Essay

The Impact of the Employee Handbook on Organizations - Essay Example What is an employee handbook There are many attorneys with internet presences offering "free advice" on handbook drafting in layman's language (Dickson Wright).Look for simple definitions on the internet and you may be disappointed; however, Schaefer goes to some trouble to distinguish it from the much larger "manual of policies and procedures": An employee handbook is designed to familiarize employees with basic company policies and benefits programs, and although it draws topics from the far broader policies manual, it presents them with much less detail. (43) Also, the reader may have direct experience of signing an acknowledgement often including a statement, a disclaimer, to the effect that you agree that the handbook does not in itself constitute an employment contract (Schaefer 43) which is a key point in understanding them. Handbooks are informational, non-contractual documents that cover the employee journey from induction to discharge. Implicit in them is the legal concept of consensus in idem ("agreement in the same thing"), widely acknowledged to be an advantage of these documents (Newcomb). For the purposes of this essay we will only consider large-scale enterprises which are usually where they are used. Handbooks can be most useful for employee induction, as a basis for resolving disputes or reducing a company's exposure to law suits arising from health and safety legislation, claims for harassment and for unfair dismissal; indeed, it could be a combination of all of these and more. Although it may be assumed that the handbook may not be well received by some employees, this misses the point in that it is a top-down, employer-created document and they must comply with its rules and spirit. In a unionized workplace, much of the content would depend of the relative bargaining strengths of the parties. Employer interests will inevitably dominate and, ironically in some respects, be separated from their employees', e.g. consider McDonalds' policies on "no solicitation, no loitering" (McDonalds 9). It may prescribe the use of safety goggles or a uniform (McDonalds 13), but also describe, say, an attitude that shop floor staff must have toward customers, as illustrated by McDonalds' conc ept of "customer delight" (10). If we compare and contrast the handbooks for a commercial concern, McDonalds Australia, the University of Chicago and The State of Iowa, we can see immediately that although covering broadly similar themes, they are tailored to the organization to take account of their particular corporate culture and aims, e.g. differing health and safety requirements, differing staff profiles (diverse age group or predominantly young people), the mission of the organization, etc.. One is aimed primarily at inexperienced young adults, one at a range of staff from clerical to collegiate, degree-educated academics and one at an American state with probably the broadest and most diverse employee profile. Handbook content is broadly similar regardless of the organization's purpose and covers matters such as absence and sick leave, benefits, dress code, health and safety, performance and appraisal,

Media - A Fine Line Between Reporting the News and Creating the News Research Paper

Media - A Fine Line Between Reporting the News and Creating the News - Research Paper Example In actual sense, the journalists are the one that create the news by making them happen newsworthy. Most news organizations deliver news to the people, but they cannot always be where the news. This has led them to use the techniques of creating that could have happened. Through journalistic beats, we find the creation and reporting of news having a clear line to fill the pressures with news demand (Kenneth 45). To support this view, journalist beats being places where news events are usually expected to happen hence providing them with a steady stream of news. The crime report is usually created but not reported, example is the one that was on Toronto Star page A8 (Richard A8). This story is an example of news collected from provincial police officers and reported making it as though the journalist was at the courthouse. This excerpt from Toronto stars exhibits the way news is created and made to be reported. The w audience cannot question the news worthiness hence a fine line betwe en creating the news and reporting the news (Schudson

Indian Stock Exchanges - Research Paper Example The researcher states that the Bombay Stock Exchange is â€Å"the oldest stock exchange in Asia† and one of the older ones in the world, having been in operation for 135 years. In 1875, it was known as the Native Share and Stock Brokers Association, and is sometimes known as the Stock Exchange Mumbai. It is astonishingly large: It has the most companies traded and is one of the top ten stock exchanges in the world with a total capitalization of $1.28 trillion. Its electronic trading handles the fifth largest number of trades in the world. It is the second stock exchange in the world to obtain ISO 9001:2000 certification and the second in the world to receive the â€Å"Information Security Management System Standard BS 7799-2-2002 certification for its BSE On-Line Trading System†. The BSE Index, SENSEX, is traded in Hong Kong. The BSE is a hybrid between an order-driven and market maker, quote-driven system. Historically, it used quote-driven systems, but anonymous scree n-based trading systems and the trading of debt and other loan-based assets is done using an order-driven system. However, quote-driven mechanisms still guide trading in many illiquid stocks. Trading occurs between 9:00 AM and 3:30 PM under most circumstances. This is about as long as the NYSE, which trades from 9:30 AM to 4:00 PM normally. The securities and stocks exchanged on the BSE are classified into a few different types of groups. â€Å"BSE has, for the guidance and benefit of the investors, classified the scrips in the Equity Segment into 'A', ‘B’,'T', ‘S', ‘TS' and 'Z' groups on certain qualitative and quantitative parameters†. These groups are classified based on the type of asset being traded, the way the asset is traded and an estimation of quality. F Group trading, for example, is of fixed income securities, while T Group trading are scrips traded per trade which is used for surveillance. S Groups are Indonext segment stocks, which means that TS Group stocks are Indonext stocks traded under trade-to-trade surveillance. Government securities are traded in the G Group. Z Group trades are companies that have failed to comply with listed requirements â€Å"and/or have failed to resolve investor complaints and/or have not made the required arrangements with both the depositories, viz., Central Depository Services (I) Ltd. (CDSL) and National Securities Depository Ltd. (NSDL) for dematerialization of their securities†. The BSE Sensex is calculated using a Free-float Market Capitalization Model. It is thirty blue-chip stocks, similar to the Dow Jones, which account for one-fifth of the capitalization of the exchange and are safe stocks with a proven track record. â€Å"The market capitalization is determined by multiplying the stock by the numbers of outstanding shares. This calculation is performed for all 30 stocks and then divided by the Sensex Divisor. The Divisor is derived from the original base value of 100 for the Sensex, so the index can be tracked over time. The Sensex is calculated every 15 seconds and then published to investors around the world in real-time† (. One study of the BSE found that a contrarian strategy, a strategy that tries to defy traditional wisdom such as Soros' famous pound-sterling coup.

Alfred Doolittle’s Lower Class Representation In Pygmalion Essay Example for Free

Alfred Doolittle’s Lower Class Representation In Pygmalion Essay Alfred Doolittles Lower Class Representation in Pygmalion Realist author George Bernard Shaws Pygmalion challenges Englands upper class to realize the pointlessness of their flamboyant lifestyle and pokes fun at this society. Shaw writes to expose the differences in the lifestyles of the social classes and how different characters react to their status. Shaw uses Alfred Doolittle and his social status to depict a character that freely accepts his status and his reaction to eventually moving up social classes. Because of his dislike of middle class morality, appreciation of and the freedom that accompanies his lower social status, and his eventual climb into the upper class, Doolittle presents a desire to remain in undeserving poverty. Doolittle, throughout the play, demonstrates a dislike for middle class morality. Before he becomes rich, Doolittle defines middle class morality as an excuse of never giving me anything. Doolittle represents a dislike for middle class morality and wishes for cheerfulness and a song like those in the upper classes. Doolittle believes middle class morality claims its victims. Eventually Doolittle becomes a victim when he is given money to lecture. Doolittle becomes apart of the upper class but dislikes being viewed as a member of this society. Doolittle says that he believes lower class men look at him and envy him. Doolittle says he, in fact, will look down to the lower class helpless and envy them. Doolittle does not like the upper classes and middle class morality. Throughout the play, Doolittle presents characteristics that suggest he accepts his current lower class social status and enjoys the freedom associated with his status. When asked by Colonial Pickering if he has no morals, Doolittle Stokes 2 establishes his status and distance from upper class characteristics by replying, I cant afford them, Governor. Doolittle comments to Henry Higgins that undeserving poverty is my line. Doolittle represents an individual who lives in poverty and accepts his current placement in society. He continues by saying, Im undeserving; and I mean to go on being undeserving. Doolittle does not want to be apart of the upper class society because so much is expected of them. Doolittle is extremely happy being in his current social status. He says, They (millionaires) dont know what happiness is. Doolittle believes the upper class is unhappy because they are living an imaginary life. Doolittle does not wish to be apart of the upper class because he would be expected to speak and act properly in order  to retain his status within the class. Doolittle, an undeserving member of the lower class, is comfortable and happy in his lower class social situation. Doolittle suddenly encounters money and is thrust into upper class society. Doolittle receives a share in a trust and is required to lecture for three thousand a year. Doolittle freely accepts the financial gain but soon realizes the social obligations that accompany it. Doolittle says, I have to live for others and not myself. Individuals who seek to take advantage of his newfound wealth surround him. Doolittle believes that everybody touches me for money. Doolittle sights one example of how individuals with money are treated better than those without money. Before he had money doctors would shove him out of the hospitals. Once the doctors realize Doolittle has money they cant live unless they looks after me twice a day. Doolittle, who retains the personality of a Stokes 3 member of the lower class, is upset because people are using him for money. Doolittle feels his is now expected to provide for everyone. Doolittle says he was happy before he got the money. Doolittle, who is propelled into the upper class, recognizes people are using him. He wishes and strives to remain the same person he was before he encountered money. Doolittles dislike of middle class morality, appreciation of and the freedom that accompanies his lower social status, and his eventual climb into the upper class presents his desire to remain in undeserving poverty. Doolittle, a character who emerges financially from poverty to being rich, strives to maintain his lower class status and the way of life they accompanied this status. Shaw, by using Doolittle, successfully presents a character that is happy with and comes to appreciate his status in the lower class society and wishes to remain in that social class.

The Social Contract Theory Essay Example for Free

The Social Contract Theory Essay The Social Contract Theory as propounded by Hobbes is based on the ratiocination that if left entirely free, human beings will act against their own self interest in the long term unless they are subjected to an authority figure which monitors their interests for peaceful co-existence on the whole. The scenario which constitutes freedom employs the concept of State of Nature while the provision that envisages an authority figure forms the basis of Social Contract. Under State of Nature, a mans own self interest when followed without consideration for others under the pretext of competition, survival and vainglory results in a sort of cataclysmic man against man scenario. In such a scenario, man starts giving reins to his baser instincts of survival without consideration for others. To avoid this, individuals need to cede their rights to a sovereign authority, in a Social Contract, that protects their interests without infringing on another’s interests. For this, it is imperative that the ruling authority be above petty prejudices and biases to bind each individual who would otherwise on their own be competitors and not always agree with their different notions of justice and fairness. The direction of actions of individuals to a peaceful co-existence requires a set of rules that forms the basis of morality which is meaningless under State of Nature, where personal interests without regard for others is the only rule at play. The covenant of Social Contract thus enforces a positive transformation of men from chaotic self serving entities to individuals enjoying order and peace in an organized society. Pleasing all being an impossible proposition, any misgivings against the authority in a Social Contract resulting due to abuse of power have to be borne as a price for peace over the chaos in State of Nature. It must be mentioned however that the individuals still retain the right to protest and demand explanations in case of excesses by the sovereign authority. References Hampton, Jean (1988).

Step by step design of a lock

Step by step design of a lock Introduction This paper outlines the step by step design of a lock in amplifier based micro-ohmmeter. This is very useful in measuring small resistances without applying large currents. And find its usefulness in tracing short circuits on printed boards containing sensitive components. The Audio Micro Ohm Meter uses synchronous detection to measure low value resistances. The circuit provides a variable frequency audio tone to indicate the resistance under test. Such a tone is invaluable when troubleshooting shorted tracks on multi-layer circuit boards because it is easier and quicker to observe 1. The source generates a 1KHz, 250mV peak square wave carrier signal that is injected into the unknown resistance, the resulting voltage across the resistor is amplified by the instrumentation amplifier. The phase reversing switch then rectifies the complementary square wave input, the rectified output is not all smooth so a low pass filter is needed. A Voltage controlled is then used to measure and indicate low value resistances such as track resistances on printed circuit boards. To provide a convenient indication, we want a ‘display that has high resolution (like a digital display) but is easy to read (like analogue meter) and that preferably doesnt even need to be looked at, so we can concentrate on the probes. To trace short circuits, the one thing we dont really need is high accuracy, since we are generally moving the probes 1. A muting detector then comes in to compare the control voltage with reference voltage. The Proteus ISIS software is used for the simulation of the circuit while a printed circuit board was used for the verification of the circuit. Resistor selection, analysis of waveforms , sensitivity and linearity of the device to supply voltage and possible improvements of the device were discussed. Excitation Oscillator One of the most useful ICs ever made is the 8-pin 555 timer and it is used in many projects. It can be used to build many circuits by just adding a few external components. NE555 is a popular version and it is suitable in most cases where a 555 timer is specified. Some low power types of the 555 are made, for instance the ICM7555, but can only be used when specified (to increase battery life) because their maximum output current of about 20mA (with a 9V supply) is too low for many standard 555 circuits. The ICM7555 has the same pin arrangement as a standard 555. The circuit symbol for a 555 is a box with the pins arranged to suit the circuit diagram: for example 555 pin 8 at the top for the +Vs supply, 555 pin 3 output on the right. Usually just the pin numbers are used and they are not labeled with their function. Standard 555 ICs create a significant glitch on the supply when their output changes state. This is not a problem in small circuits with no other ICs, but in a complex circuit a smoothing capacitor can be connected across the +Vs and 0V supply near the 555 . The 555 timer operates in different modes. The astable mode suits our design criteria. An astable circuit produces a square wave, this is a digital waveform with sharp transitions between low (0V) and high (+5Vs). It is possible that the durations of the low and high states may be different. The circuit is called an astable because it is not stable in any state: the output is continually changing between low and high. Our circuit needs a square waveform output of 4KHz, for this to be obtained an appropriate resistor value can be estimated by calculation to obtain the needed signal to drive the circuit Duty cycle The duty cycle of an astable circuit is the proportion of the complete cycle for which the output is high (the mark time). It is usually given as a percentage. The duty cycle of our circuit can be determined using Time period. The timeperiod (T) of the square wave is the time for one complete cycle, but it is usually better to consider frequency (f) which is the number of cycles per second 2. The time period can be split into two parts: T = Tm + Ts 5 Mark time (output high): Tm = 0.7 Ãâ€" (R1 + R2) Ãâ€" C1 Space time (output low): Ts = 0.7 Ãâ€" R2 Ãâ€" C1 we can determine our R2 using C3= 10nF, R1=1k and f= 4kHz we calculate our R2 as Tm = 0.7 X (1K + 33K) X 10 X 10^-9 = 238 ÃŽ ¼s While Space-time represents low output, Ts= 0.7 Ãâ€" R2 Ãâ€" C1 Ts = 0.7 X (1K) X 10 X 10^-9 = 0.7 ÃŽ ¼s T = Tm + Ts = 238 + 0.7 = 238.7 ÃŽ ¼s Duty cycle = = 99.7% The Quadrature Divider A quadrature divider, comprises a plurality of flip-flops, it includes at least two flip-flop, the flip-flops are interoperably coupled in series to produce a set dividing ratio 7. Each of the flip-flops includes two differential inputs I, two differential outputs O, and two differential clock inputs C, the outputs O, of one flip-flop is connected to the inputs I, of the next flip-flop, the outputs O, of the last flip-flop is connected inversely to the inputs I, of the first flip-flop, the flip-flops are clocked at their clock inputs C with differential clock signals in a consecutive manner which, for each flip-flop, are individually selected from quadrature clock input signals, 0, 90, 180, and 270, the quadrature divider is an even number divide-by-n circuit comprising a number of 2n flip-flops and providing a number of 4n output signals having 4n equidistant phases. 9 In our case the quadrature divider receives the square waveform signal from excitation oscillator as its clock signal . Figure 4 and 5 of the appendix show the pictorial representation of the quadrature divider as obtained from the circuit simulation and the oscilloscope graphic display. There are four output signals from the quadrature divider and they each have amplitude of about 5V but frequency of 1 KHz. This shows that the quadrature divider effectively divides the clock frequency into four amongst the equidistant phases. Attenuator An attenuator is a circuit that allows a known source of power to be reduced by a known factor usually expressed in decibels. The main advantage of an attenuator is that it is made from non-inductive resistors and therefore able to change a source or load, which might be reactive, into a resistive one that is know. The power reduction is achieved by the attenuator without introducing distortion. The attenuator used in our circuit is a pi type It is used to attenuate the 0 and 180 degrees antiphase 5V signal form the quadrature divider to 250mV at 1KHz. In order to get this value we need to select R5 in this attenuator circuit. Using Thevenins theorem. RTH = R5// (R3 + R4) where RTH = 100 ohms, R3 = 1K1ohms and R4 = 1K1 ohms. R5 = = 104.76 ohms. The best resistor to this to this value is a110 ohms resistor. So R5 = 110 ohms. figure 6 of the Appendix shows the graphical output of the attenuator with amplitude of about 250mV and frequency of 1 KHz. The attenuators gain in decibels is obtained by finding the ratio of the voltage corresponding to a known factor. Using the formula: , where R1 = 1100 ohms and the Z = 100, K = = 1.2 The value of attenuation, A in dB is obtained using K = 10 (A / 20) 1.2 = 10 (A / 20) A = 20 log 1.2 = 1.584 dB Instrumentation Amplifier An instrumentation amplifier is a variation of differential amplifier with input buffers that eliminates the need for input impedance matching making the amplifier suitable for use in measurement 5. It is a differential op-amp circuit providing high input impedances with the pleasure of gain adjustment through the adjustment of a single resistor. Instrumentation amplifier has very low DC offset, low drift, low noise, very high open-loop gain, very high common-mode rejection ratio, and very high input impedances. The instrumentation amplifier used in this circuit affected its accuracy and stability. The attenuated signal is applied across a resistor with very small resistance. The voltage drop across the resistor is small and needs to be amplified. The instrumentation amplifier does this, it composes of three op-amps arranged so that there is one op-amp to buffer each input signal and one to produce the desired output with adequate impedance matching for the function.3 The gain of the instrumentation amplifier circuit used for this micro-ohmmeter design is known to be 60 dB. Using the formula below then, Av =where AV = 60 dB, R = 10 k, 60 =, R9 = = 338.98 ÃŽ © The best resistor to this value is 340 ÃŽ © and it controls the gain of the instrumentation amplifier. The negative feedback of U3:A makes the voltage at pin 2 of U3:A to be equal to Voltage across R8. while, the voltage at pin 6 of U3:B is held to a value equal to Voltage across R14. This establishes a voltage drop across R9 equivalent to the voltage difference between V1 and V2 and subsequently a current through R9 and since no current is drawn by the feedback loops of the two input op-amps , the same amount of current through R9 must be going through R10 and R12 resistors above and below it. This produces a voltage drop between points A and B equal to V The ordinary differential amplifier part of the circuit then amplifies this voltage drop by a gain of 1. The post- differential amplifier circuit, with gain = R19 / R15 and differential input resistance = 2*R15. The two amplifiers on the left are the buffers. With R9 = Rgain removed (open circuited), they are simple unity gain buffers; the circuit will work in that state, with gain simply equal to R19 / R15 and high input impedance because of the buffers. The buffer gain is increased by putting resistors between the buffer inverting inputs and ground to shunt away some of the negative feedback; however, the single resistor Rgain between the two inverting inputs is a much more elegant method: it increases the differential-mode gain of the buffer pair while leaving the common-mode gain equal to 1. This increases the common-mode rejection ratio (CMRR) of the circuit and enables the buffers to handle much larger common-mode signals without clipping than would be the case if they were sep arate and had the same gain. Another benefit of the method is that it boosts the gain using a single resistor rather than a pair, thus avoiding a resistor-matching problem. The ideal common-mode gain of an instrumentation amplifier is zero. The common-mode gain of the instrumentation amplifier used in this design is near zero because of the equally numbered resistors and by the matched common-mode gains of the two buffer op-amps of the instrumentation amplifier. To obtain a closely matched resistors is difficult, as is optimizing the common mode performance of the input op-amps. All resistors are of equal value for this instrumentation amplifier except for R9. This method has the advantage of possessing extremely high input impedances on the input voltage across R=39 because they connect straight into the non-inverting inputs of their respective op-amps and adjustable gain that can be set by a single resistor. The lowest gain possible is obtained from the above circuit with R9 completely open (infinite resistance), and that gain value is 1. The output of the instrumentation amplifier is an anti-phase square wave signal from the that connects to the phase shift detector for further modification. Lock-In Amplifier A lock-inamplifier otherwise known as a phase-sensitive detector is a type of amplifier that can extract a signal with a known carrier wave from extremely noisy environment. It is a homodyne with a very low pass filter making it very narrow band. Lock-in amplifiers utilizes mixing, via a frequency mixer, to convert the signals amplitude and phase to a DC—in fact a time-varying low-frequency—voltage signal. It is often used to measure phase shift, even when the signals are of a high value and of high signal-to-noise ratio, and do not need any other improvement.To obtain signal at low signal-to-noise ratios, it is necessary that a strong, undiluted reference signal is made available at the same frequency as the signal to be measured. Phase Difference Two oscillators that have the same frequency and different phases that is, a phase difference, the oscillators are said to be out of phase with each other. The amount by which such oscillators are out of step with each other can be expressed in radians from 0 to 2Ï€ or in degrees from 0 ° to 360 °, If the phase difference is 180 degrees (Ï€ radians), then the two oscillators are said to be in antiphase. If two interacting waves meet at a point where they are in antiphase, then destructive interference will occur. It is common for waves of electromagnetic (light, RF), acoustic (sound) or other energy to become superposed in their transmission medium. When that happens, the phase difference determines whether they reinforce or weaken each other. Complete cancellation is possible for waves with equal amplitudes. Phase compensation This is the correction of phase error (i.e., the difference between the actually needed phase and the obtained phase). To obtain stability in an operational amplifier a phase compensation is required. To keep a phase margin in the phase compensation a capacitor/RC network is usually used . A phase compensator works by subtracting out an amount of phase shift from a signal which is equal to the amount of phase shift added by switching some additional amplifier stages into the amplification signal path. Low-Pass Filter A low-pass filter is a filter that passes low-frequency signals but attenuates (reduces the amplitude of) signals with frequencies higher than the cutoff frequency. An ideal low-pass filter completely eliminates all frequencies above the cutoff frequency while passing those below unchanged: its frequency response is a rectangular function, and is a brick-wall filter 8. If we need to get rid of an interfering signal in order to get a lot of attenuation, several RC filters can be cascaded. Unfortunately, the impedance of one RC section affects the next. What this means is that the transition between the pass and stop bands will not be sharp. A sharp transition helps reduce the interfering signal without causing degradation to the desired signals. In this case, the Sallen-Key active filter can do the job well. This circuit uses a 2-pole filter. Cascading a number of stages can give a steep attenuation transition with a very sharp knee. This cut-off frequency aids in selecting the R20 an d R22 resistor values to be used in the low pass filter design to average noise in the DC signal 6. The required Q for the butterworth filter = 1.414. The op-amp stage is a unity gain follower when R20 = R22. if C9 and C10 are equal, then the Q = 1.5858 for Butterworth response. Using convenient near values gain of 1.56 in the formula, R20 = R22 = Q / (4 ·Ãâ‚¬Ã‚ ·fo ·C9) where, fo = cut-off frequency = 4Hz, C9 = C10 = 0.1ÃŽ ¼F R20 = R20 = 310.31kÃŽ © The nearest standard resistor value to this calcualted resistor value is 330k Voltage Controlled Oscillator A voltage-controlled oscillator is an oscillator whose frequency is determined by a control voltage. As the control voltage causes the frequency to rise slowly until it hits a maximum and then falls back to the starting frequency. The first op-amp is an integrator(U7:A). A voltage divider puts the + input at half the control voltage. The op-amp attempts to keep its input at the same voltage, which requires a current flow across the 100k to ensure that its voltage drop is half the control voltage. When the MOSFET at the bottom is on, the current from the 200k goes through the MOSFET. Since the 100k resistor has the same voltage drop as the 100k but half the resistance, it must have twice as much current flowing through it. The additional current comes from the capacitor, charging it, so the first op-amp must provide a steadily rising output voltage to source this current. When the MOSFET at the bottom is off, the current from the 200k goes through the capacitor, discharging it, so a steadily falling output voltage is needed from the first op-amp. The result of the operation of this integrator circuit is a triangular waveform confirmed by figure 13 of the appendix. The capacitance of the capacitor in our circuit is determined thus: The second op-amp is a Schmitt trigger. It takes the triangle wave as input. When the input voltage rises above the threshold of 3.33 V, it outputs 5 V and the threshold voltage falls to 1.67 V. When the input voltage falls below that, the output goes to 0 V and the threshold moves back up. The output is a square wave. Its connected to the MOSFET, causing the integrator to raise or lower its output voltage as needed 4. Figure 14 shows the graphical representation of this circuit . The variation of the supply voltage from 3V to 9V while observing the output signal frequency obtains the sensitivity of the overall voltage- controlled oscillator circuit to supply voltage. From the test observation, the VCO produced no output signal at 3Vand beyond 6.2V. The below table shows the values obtained for the during the sensitivity test of the voltage-controlled oscillator. Using the power supply sensitivity formula Sensitivity Percentage change in frequency = Percentage change in power supply voltage = Between 5V to 6V, the percentage change in power supply voltage = = 20% While the percentage change in frequency is = 3.575% VCO sensitivity to this supply voltage variation = = 17.875 % Between 4V to 5V, the percentage change in power supply voltage = = 25% While the percentage change in frequency is = 12.21% VCO sensitivity to this supply voltage variation = = 48.84% The inference from the above calculation shows that the sensitivity of this lock-in amplifier based micro-ohmmeter to power supply voltage increases with reducing supply voltage. The tuning range of the VCO refers to the range of oscillation frequencies Two important parameters in VCO design are linearity and sweep range. Linearity correlates the change in frequency or the VCO output to the change in the control voltage. The sweep range is the range of possible frequencies produced by VCO control voltage. The linearity Muting Detector Circuit The filtered output from the phase sensitive detector is a control voltage which, with Zero input ( short circuited probes) is about Vg volts . It goes more positive with increasing signal level. With maximum input(open circuited probes) the voltage will saturate near the positive supply rail. This would result in a loud high pitched tone from the oscillator, which is not what we want. We want the it to be mute when the probes are disconnected and to do this another operational amplifier is brought in to compare the control voltage with a reference voltage. Whenever the control voltage goes higher than the reference, the output will go negative. This allows a small current to be drawn through D1 and R25, which will keep the oscillator transistor switched off, stopping oscillation. The output voltage of an AM synchronous detector is compared with a reference potential level by a voltage comparator. A muting device connected with the output of the detector is controlled by a control circuit connected with the comparator. Through this control circuit, the detector output is immediately muted when the detector output level falls below the reference potential level, and the muting of the detector output is removed after a predetermined retardation when the detector output level exceeds the reference potential level.

Point of view Tell-Tale Heart Essay -- essays research papers

Essay #1: â€Å"Tell Tale Heart†. Poe writes â€Å"The Tell Tale Heart† from the perspective of the murderer of the old man. When an author creates a situation where the central character tells his own account, the overall impact of the story is heightened. The narrator, in this story, adds to the overall effect of horror by continually stressing to the reader that he or she is not mad, and tries to convince us of that fact by how carefully this brutal crime was planned and executed. The point of view helps communicate that the theme is madness to the audience because from the beginning the narrator uses repetition, onomatopoeias, similes, hyperboles, metaphors and irony. "True!--nervous--very, very dreadfully nervous I had been and am; but why will you say that I am mad? The disease had sharpened my senses--not destroyed--not dulled them. Above all was the sense of hearing acute. I heard all things in the heavens and in the earth. I heard many things in hell. How, then, am I mad?" "...Now this is the point. You fancy me mad.

Leonardo Da Vincis Time in Milan :: essays research papers

The objective of this essay is to provide an explanation of Leonardo da Vinci’s life and work as an artist in context with his time spent in Milan. Following an initial introduction to Leonardo’s formative years in Florence (and his apprenticeship to the sculptor and painter Andrea del Verrocchio, 1435-88), I will attempt to explain the significance of his presence in Milan with detailed descriptions of his work there. Giorgio Vasari (1511-74) was also an artist and architect, but is perhaps better known for his book on the lives of well known painters, sculptors and architects (published 1550; from Cimbue to his autobiography which was included in a revised edition): â€Å"Vasari's book offers his personal evaluation of the works of these artists, as well as discussions on the state of the arts. His easy, natural writing style helped to make his book one of the most enduring of art histories.† His reflections on Leonardo’s life include insight specifically relating to his unusual character and the intellectual merit of his life’s work. Using this evidence I hope to provide valid observations on Leonardo’s significance as a father of the High Renaissance. Leonardo (who was christened Lionardo, the name to which Vasari refers) was born near the small town of Vinci on 15th April 1452. The town was situated in the Florentine province of Italy, where his father, Ser Piero was a notary. According to Vasari, Leonardo was somewhat of a child prodigy in his studies, but he showed little commitment to one single area, constantly finding new interests in other subjects: â€Å"Thus in arithmetic, during the few months that he studied it, he made such progress that he frequently confounded his master by continually raising doubts and difficulties. He devoted some time to music †¦ Yet though he studied so many different things, he never neglected design and working in relief, those being the things which appealed to his fancy more than any other.† Being very conscious of his son’s talents, Ser Piero moved to Florence with Leonardo and his wife (not Leonardo’s mother, as he was illegitimate and never took his father’s name) to utilise them professionally. Being a friend of the artist and sculptor Andrea del Verrocchio (1435-88), Ser Piero convinced him to recruit Leonardo as an apprentice by the promise shown in his work. Verrocchio strongly encouraged da Vinci, and his admiration of his student's talents convinced Verrocchio to allow Leonardo to participate in the creation of his own paintings and sculptures.

American Financial Crisis Essay -- Economics Economy

The US Financial System: A Crumbling Empire The financial system has been crucial to the role of free enterprise. â€Å"Financial markets have come to supply non-financial corporations with mechanisms for managing their risks and for comparing and evaluating diverse investment opportunities in a highly complex global economy† (Cindin, 2008). â€Å"However, despite the lifetimes it took to build our financial institutions, bad luck and careless risk management have jeopardized careers and mortgaged these institutions’ futures†(Wallace, 2008). The nation is currently attempting to deal with the biggest financial crisis since the Great Depression. It is now imperative that a way be found which will re-regulate finance without undermining finance’s needed innovative capacity. The origin of the financial crisis can be dated back to 2006. During that period in time, companies began buying trillions of dollars of complex financial products called ‘structured credit derivatives’. The value of these derivatives quickly escalated to over one-hundred trillion dollars due to the high demand from banks around the world. â€Å"These paper investments were supposedly backed by loans on houses, cars, businesses, and credit cards† (Francis, 2008). Nevertheless, several issues have erupted from the sale of these paper investments. The production and trading method for derivatives is unclear, and no one really knows what credit risk is transferred to whom. Basically, banks were fighting over assets with questionable values. Even though the sale of derivatives has disrupted our economy, it is not the primary reason for which the financial system is now in distress. The reckless selling of mortgage loans has lead to the eventual breakdown of our financial... ..., Jane & Francis, Theo. The Financial System Bailout: Deal or No Deal? (2008). Business Week.

Need for sustainable architecture on development land in the South-East of England

The intent of this thesis is to discourse and measure the force per unit area on development land in the South- East of England, and how that force per unit area relates to the demand for sustainable architecture. The grounds for there being force per unit area on development land in the South-East of England will be described and analysed, as will any differences with the other parts of Britain. The grounds for puting aside or utilizing the available development land and why sustainable architecture should be adopted in the South-East of England will be to the full evaluated. As will be demonstrated there are assorted and viing factors that seemingly increase the force per unit area to do full usage of all available development land in the South-East of England. The available development land in the South-East of England is in high demand to be used for the building of domestic lodging, every bit good as for commercial, leisure, and industrial edifice programmes. To a big extent cardinal authorities and local governments have attempted to command the building of such new edifice programmes through systems of urban planning, every bit good as edifice ordinances that have applied across the whole of Britain. The grounds why the South-East of England should hold a demand for sustainable architecture will besides be examined in deepness. The instance for doing all the new building undertakings designed around the constructs of sustainable architecture shall besides be examined, to discourse whether more environmentally focussed edifice designs will decrease t he impact of new building programmes, every bit good as cut downing long-run pollution. IntroductionASustainable architecture and the usage of development land are closely linked with the patterns and theories of what form the footing of urban and rural planning, every bit good as thoughts refering the necessity for long-run environmental sustainability. Urban, and to a lesser extent rural planning, became more widespread in their application throughout Britain after 1945, when increased degrees of cardinal authorities intercession were experienced in many societal and economic Fieldss. Planning was deemed to be the best manner of work outing Britain ‘s lodging jobs ( Taylor, 1998 p. 3 ) . Increased degrees of urban and rural planning were justified at the terminal of the Second World War due to the demand for extended post-war Reconstruction. The South-East of England in general, and London in peculiar had suffered from widespread bomb harm, which meant that to the full or partly destroyed houses, mills, and retail units had to be replaced by good planned edifice s which would be an betterment upon the old edifices. In the immediate post-war period it was believed that a systematic usage of town and state planning would be indispensable for the Reconstruction of Britain, with a much higher criterion of edifice to fit higher employment, the public assistance province, and the National Health Service. The intent of these policies and establishments was to prolong life and advance good wellness throughout the whole population ( Meller, 1997 p67 ) . The increased usage of urban and rural planning was non intended to protect the environment in an ecological manner, or so to advance sustainable architecture, instead it was greatly expanded in range to do the most rational usage of scarce development land. However, there would be steps adopted which would conserve big countries of countryside, and give protection despite the demand to re-house 1000000s of households in 1945 ( Southall, 2000 p. 336 ) . There were groups that wished to conserve specific countries that supported rare signifiers of animate being and works life, and even groups that wished to continue old historical edifices, every bit good as edifices distinguished by their architectural manners ( Meller, 1997 p67 ) . When added together such groups did non compare to an ecological anteroom that intended to alter agricultural, architectural, or industrial patterns to protect the environment. These groups nevertheless, were able to to a great extent act upon the determi nation to curtail urbanization taking over the countryside. Post-war Reconstruction was the accelerator for the largest programmes of publically funded building in Britain. Public outgo was needed due to the sheer graduated table of Reconstruction required, with London and the South-East of England being a major donee of those programmes. Architecture and planning were used for these large-scale programmes instead than merely for single edifices. The engagement of cardinal authorities in the promoting and support of large-scale public edifice programmes and the usage of development land was high until the early portion of the 1970s ( Greed, 1996 p. 35 ) . Such wide-ranging edifice programmes were non merely intended to replace the edifices destroyed during the Second World War. The post-war edifice programmes were besides intended to replace the slums in the interior metropoliss of London, Birmingham, Liverpool, every bit good as elsewhere. The building programmes were intended to do the South-East of England a much more hospitable topographic point to populate in, merely as the remainder of Britain was besides intended to be like ( Sheail, 2002 p. 62 ) . New building and redevelopment of bing houses was an imperative, as ‘2 million of them condemned and another 3 million lacking in necessities ‘ ( Southall, 2000 p. 337 ) . The South-East of England besides benefited from the building of new towns such as Milton Keynes and Stevenage that were planned as full towns with purpose built domestic lodging and concern premises. The Atlee authorities was so acute upon the creative activity of new towns to work out the post-war lod ging deficits that it regulated such building through the New Town Act of 1946 ( Sheail, 2002 p. 62 ) . The building of the New Towns was considered to be indispensable for both high economic growing and for work outing the national post-war lodging deficit. The Atlee authorities regarded the new towns as being extremely good to people ‘s wellness as they moved off from major metropoliss and industrial countries to topographic points with cleaner air ( Meller, 1997 p67 ) . In ecological footings such building was harmful to the environment as more land was built upon and it meant a greater sum of pollution from traffic emanations, though of class cipher understood such deductions at that clip. Improvements in conveyance substructure and increasing degrees of auto ownership meant that the new towns were economically feasible, every bit good as leting their dwellers to transpose to the major metropoliss to work in them ( Daniels, Bradshaw, Shaw, & A ; Sidaway, 2005 p. 147 ) . Ur ban planning was therefore considered to be really utile for the advancement and development of London and the South-East of England, which traditionally has been the most thickly settled and comfortable part of Britain. Urban planning was besides intended to increase the prosperity degrees of the other parts in Britain to be every bit high as possible to fit the degrees achieved in the South-East of England ( Southall, 2000 p. 337 ) . Controlled enlargement of urban countries into the new towns was intended to work out the immediate post-war lodging deficit and resuscitate the British economic system, whilst go forthing the great majority of the countryside untouched by new lodging building ( Taylor, 1998 p.3 ) . Previous betterments in agricultural techniques meant that farming became more efficient nationally which had quickened the gait of urbanization in Britain as a whole. Urbanization in Britain had already had a strong impact upon the environment that went beyond the replacing of the countryside with fouling mills and unhealthy slum lodging ( Southall, 2000, p. 335 ) . Higher harvest outputs from less land had the effect that more land in rural countries became available to be used as development land. The greater handiness of former agricultural land meant that is was easier to happen adequate land to build new towns or spread out bing metropoliss across Britain. Urbanization was a procedure that was accelerated by the demand of industrial towns and metropoliss to happen workers to go on their enlargement ( Goudie & A ; Viles, 1997 p. 5 ) . To get down with, the bulk of new places were traditional manner houses that formed big council house estates right across the state, in architectural footings there was really small invention or thought given to doing the new lodging stock architecturally sustainable or environmentally friendly. More attending was alternatively devoted to doing all new houses comfy, clean, and guaranting they were being built to last ( Greed, 1996 p. 35 ) . The new places were intended to be better and larger than the 1s that they had replaced. The bulk of big metropoliss and the new towns in Britain had 1000000s of council houses built in their countries between 1945 and the early 1970s. However, it was much harder to happen equal sums of development land in interior metropolis countries which led to the edifice of high rise tower blocks which allowed a greater figure of people to be housed without increasing the entire country of the development land required ( Sheail, 2002 p. 62 ) . Unfortunately, high rise tower blocks constructed during the 1960s and the 1970s in the South-East of England, every bit good as nationally failed to be an equal signifier of long- term and sustainable architecture that allowed people to be housed in safety or comfort. The failure of many high rise tower blocks to be sustainable signifiers of lodging had the affect of increasing the force per unit area on development land. It has besides meant that tower blocks have had to be refurbished or more often demolished ( Meller, 1997 p. 63 ) . As the image below shows the 1950s and the sixtiess besides witnessed the building of low-rise flat blocks which have proved to be longer enduring than tower blocks built during the same period of clip. The image is of flat flats constructed in Ham Common in Richmond between 1955 and 1958 ( Frampton, 1997 p. 266 ) . Although the sum of new lodging building was considerable non all the available land had been developed or built upon. Land remained set aside for agricultural intents, whilst other land was left un-built upon and non ever used for farming. The land that was left entirely and was set aside and therefore non allowed to be used for domestic lodging or industrial sites were referred to as the green belt. The green belt was created to move as a buffer zone between urban and rural countries as a agency to restrict urbanization ( Greed, 1996 p. 82 ) . Cardinal authorities set aside countries that were designated as green belt zones to continue the countryside nationally every bit good as entirely in the South-East of England. Although, it was possible to construct on green belt land the procedure of deriving be aftering permission from cardinal authorities and the relevant local authorization was a long drawn out one which deterred most belongings developers and building houses from making so. Local involvement groups have frequently being extremely vocal in their resistance to any strategies that have been suggested ( Clapp, 1994 p. 138 ) . Clapp estimated that with national Parkss and designated green belt zones that in England and Wales ‘more than a fifth of the countryside now has stringent protection against development ‘ ( Clapp, 1994 p. 140 ) . Therefore, the majority of available development land was concentrated in urban countries, frequently referred to as brown field sites ( Greed, 1996 p. 82 ) . For cardinal authorities there are advantages for utilizing brown field sites ( Kim & A ; Rigdon, December 1998 p. 5 ) . For case, utilizing such sites allows for economic regeneration, employment creative activity every bit good as less force per unit area to construct on green belt land. Recycling land on brown field sites is a method of continuing rural countries being used as development land ( Clapp, 1994 p.139 ) . The force per unit area to utilize greater sums of development land has arguably increased significantly in recent old ages throughout Britain as a whole. The force per unit area to utilize development land has risen due to a combination of societal, economic, and political factors. For case, in societal footings the demographic alterations to the British population have had important, and it could even be argued, profound effects upon the demand for development for new building programmes. These demographic alterations have occurred as a effect of the British population ripening, the increasing figure of grownups who live on their ain, every bit good as the major addition in the figure of immigrants who have settled in Britain in the past decennary or so. These alterations have meant that more people within Britain are seeking a higher figure of topographic points to populate in. Another ground for the raised degrees of force per unit area upon development land is caused by the poss ible fiscal additions from constructing new houses, every bit good as new retail or industrial composites. The degree of fiscal additions that could be made has been boosted since 1979 by the switching off from the publically funded lodging programmes to a market led attack to finding the rates of new lodging building and the ownership of bing lodging ( Allmendinger and Thomas, 1998 p. 5 ) . Of class even greater Numberss of domestic places and retail premises has a knock on consequence on the sum of substructure such as schools, infirmaries, and roads which are required in Britain as a whole. The edifice of new signifiers of substructure will merely increase the environmental impact of new building programmes ( Kim & A ; Rigdon, December 1998 p. 5 ) . A fuller account and a more comprehensive scrutiny of the increased force per unit areas on the development land in Britain in general will be presented in the specific chapter on development land. The more elaborate rating of the for ce per unit areas upon development in the South-East of England will be presented in the specific chapter about the South-East of England. Not merely has at that place been force per unit area to utilize more development land in Britain by and large and in the South-East of England in peculiar, there has been more force per unit area for new building programmes to utilize edifice techniques and engineering linked with sustainable architecture. Sustainable architecture may hold been a construct, which started in the United States, yet it could be really of import to set its thoughts into action across the Earth ( Kim & A ; Rigdon, December 1998 p. 5 ) . The impression of sustainable architecture is in itself influenced by thoughts about doing or enabling architecture maximize the public-service corporation and the subsequent life span of all new building, whilst understating the sum of resources needed in the initial building and the care of edifices. Sustainable architecture, when possible, uses resources that is renewable, reclaimable, and biodegradable. There are assorted motives for following sustainable architecture when it comes down to the building and the completion of all new edifice programmes. Motivations that include the minimising of development land used, every bit good as doing usage of new engineering to conserve energy, the preservation or recycling of finite resources, every bit good as cut downing the degrees of H2O ingestion. Reducing the degree of pollution and trying to decelerate down the effects of planetary heating are besides factors in the publicity and execution of sustainable architecture ( Kim, Rigdon, & A ; Graves, August 1998 p. 5 ) . Of class, there is the influence of statute law upon the usage of sustainable architecture techniques to cut down the environmental and ecological impact of new building programmes. Property developers and building houses have to follow with steps to protect the environment introduced by the British authorities and the European Union ( Hough, 2004 p. 190 ) . As will be shown in the specific chapter about sustainable architecture the bulk of methods used to better environmental sustainability are comparatively straightforward to integrate into the designs of new edifice programmes, and in some instances into bing edifices. Sustainable architecture could be achieved by utilizing building stuffs that are less detrimental to the environment, or stuffs that have been obtained from recycled and renewable resources. Making edifices as environmentally sustainable as possible during new building undertakings ( as will be examined in greater deepness ) will accomplish the over all aims of those that pattern and argue for the execution of sustainable architecture. It is most practical to put in characteristics or equipment which enhances environmental sustainability during new building undertakings instead than afterwards. The force per unit areas to follow sustainable architecture in many ways are contradictory, yet are besides connected with the force per unit areas to raise the degrees of development land used up for new edifice programmes. Other motives for following sustainable architecture include using steps that are demands for deriving be aftering permission, every bit good as guaranting that all new edifices comply with all the minimal criterions for safeguarding the environment set by the British authorities and besides by the European Union. The British authorities has set criterions for domestic and retail edifices since the 1950s. For case, to free London of its antecedently renowned smog and fog by cut downing smoke emanations from domestic places and mills likewise under the protections of the Clean Air Act. The European Union has taken a greater involvement in advancing environmental sustainability since the 1980s, believing that such actions to protect the natural environment on a regional instead than a national footing would be far more effectual in making so ( Hough, 2004 p. 190 ) . ‘Urban Planning and the British New Right ‘ , by Allmendinger and Thomas was chiefly used as a beginning of mention for the ways in which the Conservative authoritiess between 1979 and 1997 altered lodging and economic policies in Britain. This book besides contained information about the debut of more extended authorities environmental protection policies, which were started during that period of Conservative disposal. The book demonstrates the contradictions between the strong Conservative support for free market economic sciences and the increasing apprehension that cardinal authorities needed to move to protect the environment. Brian Clapp ‘s ‘An Environmental History of Britain from the Industrial Revolution ‘ is a good beginning of information with respect to development land and the impact of the green belt zones on restricting edifice programmes to already urbanized countries. The book provides a utile penetration into the constitution and the continued care of green belt zones in modern Britain. ‘An debut to Human Geography Issues for the twenty-first century ‘ by Daniels, Bradshaw, Shaw, and Sidaway proved a utile beginning of information about development and the environmental impacts of human activity such as building edifices and utilizing fossil fuel in edifices. The book assists in explicating why such impacts on the environment would supply a accelerator for sustainable architecture.‘Modern architecture a critical history ‘ by Kenneth Frampton was used as a beginning of images and mention for information about architectural manners and edifice stuffs. There was besides a brief subdivision refering the planning of the new town constructed at Milton Keynes during the early 1970s.‘The Earth Transformed an debut to Human Impacts on the Environment ‘ by Goudie and Viles was used to obtain information about development land and the impact of unsustainable architecture and edifice techniques upon pollution degrees and planetary heating. Th e book contained information about the harmful effects of planetary urbanization and industrialization. ‘Cities & A ; Natural Process A footing for sustainability ‘ , by Michael Hough was a utile mention book for discoursing development land and issues that relate to heightening environmental sustainability. This book was besides utile because there was a greater focal point upon Britain within it. The book contained suggestions and illustrations of how sustainability could be achieved with the aid of sustainable architecture. ‘Sustainable Architecture: Introduction to Sustainable Design by ‘ Kim and Rigdon is an article which explores the theoretical and practical background to sustainable architecture. It was used to derive information for the chapter, which dealt with sustainable architecture specifically. That information was besides for the chapter refering the demand for any new building programmes in the South-East of England to encompass sustainable architecture. ‘Pollution Prevention in Architecture Introductory Module ‘ by Kim, Rigdon, and Graves provides farther theoretical and practical penetrations into the thoughts contained within the impression of sustainable architecture. This article contained strong statements as to why sustainable architecture should be implemented across the universe and non merely in a individual specific part of one peculiar state. This article proved a sound mention for the chapters refering sustainable architecture and the necessity of its usage in the South-East of England. ‘Towns, programs, and society in modern Britain ‘ by Helen Meller was used to derive background cognition of the constitution of a more vigorous and restrictive planning regulative model brought into operation after the terminal of the Second World War. That information was so included within the debut and the specific chapter covering with the force per unit areas upon the usage of development land.‘Urban and Environmental Planning in the UK ‘ , by Yvonne Rydin provides utile information refering the protection of the environment through planning ordinances and limitations. Provides good mention stuff as to how the British authorities and the European Union have attempted to cut down environmental harm through limitations on development land and edifice or other ordinances to cut pollution and enhance sustainability. ‘A History of Britain 3, End of Empire 1776 2000 ‘ , by Simon Schama was used to derive information as to why the Conservative party did non turn over the drawn-out proviso of council houses introduced by the Atlee authorities until after 1979. The book besides had information about the ideological alterations that Margaret Thatcher brought into Britain and the effects of such alterations. ‘An Environmental History of Twentieth Century Britain ‘ by John Sheail was a book, which discussed the developments within the environment of Britain between 1900 and 2000. Sheail examines how the apprehension of environmental issues in Britain developed in the latter portion of the 20th century. The book was enlightening in relation to the development of policies that were intended to protect the environment and promote sustainability. ‘The City In clip and infinite ‘ by Aidan Southall was a book used to help with the description and rating of the usage every bit good as the limitations placed upon the handiness of development land within Britain. Southall ‘s history in peculiar provided information refering the effectual regeneration of brown field sites within the immediate locality of London besides supplying an penetration into the building of the new towns in the wake of the Second World War. ‘Ecological Architecture: A critical history ‘ by Steele provided some utile practical and theoretical information about the constructs and the designs of sustainable architecture. ‘Life Cycle Analysis for Automobiles ‘ , by Sulivan and Hu was used entirely for the informations refering the sum of energy needed to bring forth aluminum, polyethene, PVC and steel, comparing the ingestion to bring forth the stuffs new with when those merchandises are recycled. ‘Urban Planning Since 1945 ‘ by Nigel Taylor was a extremely utile beginning of information with respect to the development and the continuance of be aftering limitations every bit good as edifice ordinances. The information about the utilizations of town and state planning besides the motives for the constitution and the continuance of green belt land countries was of great usage. Taylor besides included some compendious information about environmental sustainability within this book. Brenda Vale ‘s ‘Green Architecture: Design for a Sustainable Future ‘ is a good debut to the constructs and the designs most strongly linked with sustainable development. Prior to the start of the 20th century there was really small formal or legal ordinance or planning undertaken when it came down to the usage of development land. There was in consequence small to forestall the building of new edifice programmes, allow alone impressions about restricting the size and the range of such programmes to protect the environment or advance ecological sustainability ( Taylor, 1998 p. 3 ) . Cardinal authorities by and big did non step in to forestall persons, concerns of assorted sizes, or so local governments from utilizing development land in any manner that they wished to make so. The cardinal authorities was willing to allow any parties to build new edifices upon such development land, particularly if the party responsible for building such edifices already owned the land, which was been built upon ( Greed, 1996 p. 2 ) . The freedom with which new edifices could be built was demonstrated by the ability of the bulk of landholders to take the manner of arch itecture in the building of their places, mills, or stores. Landowners had the option of doing their edifices every bit expansive as possible or as inexpensive to build as possible ( Kim & A ; Rigdon, December 1998 p. 5 ) . They did non hold to see that their right to construct on their land would be restricted by the location of that land in relation to the nearest metropolis or its topographic point in the countryside. Landowners and their designers did non believe that there was any profound demand to alter what they built or how they built it in order to protect the environment and promote sustainability ( Sheail, 2003 p. 2 ) . Those edifice ordinances that did be were by and large really minimalist in their existent nature, and were normally introduced on an ad hoc footing. Architecture and the development of land were more likely to be influenced by alterations in engineering or betterments in economic development, every bit good as alteration in manner and manners ( Meller, 1997 p. 63 ) . For case, these houses started to hold gas, electricity, and H2O supplies installed. These supplies of public-service corporation services were regulated by the cardinal authorities ( Daniels, Bradshaw, Shaw, & A ; Sidaway, 2005 p.115 ) . Those services were besides supplied to mills and stores, which were progressively capable to wellness, and safety criterions that were intended to forestall accidents, yet paid no attending to the land that they happened to be constructed on ( Sheail, 2003 p. 2 ) . The 19th century witnessed a quantum leap frontward in the sum of land, which was built upon due to a raising population every bit good as increased degrees of industrialization. These factors happened to co-occur with the development of improved substructure such as roads, railroads, sewerage systems, public infirmaries, and schools. The development of such substructure required big measures of land, labor, and resources to be successfully completed, whilst in bend advancing higher degrees of industrialization and the migration of people from the countryside to the spread outing metropoliss. Some metropoliss and parts benefited economically from such industrialization more than others did. In Britain, industrialization benefited the parts environing Birmingham, Manchester, Liverpool, and Glasgow. Over all though London and the South-East of England retained their place as the most comfortable part within Britain. Industrialization came at a cost, viz. pollution and greater degrees o f societal inequality ( Southall, 2000 p. 335 ) . The development of gas, electricity, and H2O supplies alongside sewerage systems made domestic houses more comfy to populate in and mills more productive due to holding greater efficiency ( Daniels, Bradshaw, Shaw, & A ; Sidaway, 2005 p.115 ) . Before a system of urban and rural planning were introduced there was no specifically set aside development land. Market forces determined the usage of land and what if anything was built upon it. If landholders found that their land was most productively used for agricultural intents so it would stay as agricultural land ( Taylor, 1998 p. 3 ) . If, nevertheless more money could be made from edifice houses, stores, or mills on their land, so that is what normally happened to that land. Landowners could besides be tempted to sell their land to belongings developers, building houses, or industrial endeavors if they were lucky plenty to have land that those other parties felt in pressing demand of developing ( Meller, 1997 p. 62 ) . It was market forces that drove the industrial revolution in Britain every bit good as besides advancing the procedure of urbanization. The procedures of industrialization and urbanization meant that metropoliss such as London, Birmingham, Manchester, and Gl asgow greatly expanded in footings of both their geographical countries and their entire population degrees, which led to shrinkage in the size of rural countries in Britain as a whole ( Southall, 2000 p. 335 ) . It was besides market forces that determined the location, size, and range of lodging, mills, and commercial edifices. There were no restrictions to the size, location or range of such edifices, and perfectly no attending was given to the environmental effects of these edifice programmes ( Sheail, 2003 P 2 ) . The absence of edifice ordinances and limitations on the usage of land meant that there was a great trade of unhealthy and deficient slum lodging, which caused widespread unwellness. Illness occurred besides reflecting the poorness of those people that were unfortunate plenty to hold to populate in such countries ( Daniels, Bradshaw, Shaw, & A ; Sidaway, 2005 p.115 ) . Planing ordinances would hold doubtless improved conditions, for case presenting proper sanitation into the slums or holding deficient lodging replaced by higher quality houses for people to travel into ( Southall, 2000 p. 335 ) . In rural countries frights that heavy industry and unsightly slums would finally over take all the land within their close propinquity prompted the foundation of administrations dedicated to the physical saving of the countryside, the rural manner of life, and its wildlife ( Clapp, 1994 p. 138 ) . The countryside saving administrations would finally hold a strong influence on the constitution of the green belt zones and the restricted handiness of development land in the more preponderantly rural countries of Britain ( Allmendinger and Thomas, 1998 p. 55 ) . It was after the terminal of the First World War that the cardinal authorities and local governments took a greater involvement in the building of lodging and how land was really being used in domestic lodging and industrial or commercial building programmes. The function of the market in make up one's minding how many houses were built and the location of where those houses were constructed was reduced with the development of council houses ( Taylor, 1998 p. 3 ) . The proviso of low-cost lodging built by local governments and subsidised by cardinal authorities support meant that there was increased public engagement in the finding of land use. The usage, maltreatment, or the non-use of land was no longer entirely determined by market forces. The engagement of cardinal authorities and local governments was intended to cut down poorness, sick wellness, and societal exclusion. At no point in the inter-war period were steps taken to present town and state planning with the purpose of pr otecting the environment or advancing sustainability as cipher considered such stairss were necessary. The First World War had merely witnessed really minimum degrees of belongings harm caused by German naval onslaughts and bombing foraies on Britain, so there was no widespread demand for pressing Reconstruction programmes as there would be at the terminal of the Second World War ( Clapp, 1994 p. 138 ) .
