The Federal Government and Laissez-Faire Essay Example for Free

The Federal Government and Laissez-Faire Essay The period of American history from 1865 to 1900 consisted of much controversy concerning economic control. Individual enterprises fought diligently to dominate economic affairs but the government was obligated to intervene when unjust activity was apparent. It was unanimously believed, among businessmen, that the government should have very little say in economic issues, the basis for Laissez-Faire. This policy invited the rights of the public consumer to be violated. As a result of the unjust treatment by the enterprises, it was necessary for the government to step in. The Interstate Commerce Act was enacted to limit the freedom and wrongful capital gain of railways to benefit the people. The Senate passed the Sherman Antitrust Act, heavily influenced by the monopolies, to prevent trade restrictions. Freedom and independence are extremely valuable aspects in any setting but can only remain if utilized responsibly. The successful individual enterprises were determined to maintain the Laissez-Faire policy. In Document A, Amasa Walker is quoted saying, Economically, it will ever remain true, that the government is best which governs least. When the government is too involved in the economy, a great many regulations are set and the corporations become less prosperous because their effective methods are limited. A New York City merchant, Daniel Knowlton, (Document B) has a supporting opinion pertaining to the proper functions of the government. He believes the government is in place to maintain domestic tranquility, defend the people from invasion, and protect them when traveling. Every merchant and big business owner alike new theyd benefit under the Laissez-Faire policy. The Interstate Commerce Act was a major intervening action taken by the Federal government in 1887. The act prevented discrimination and promoted reasonable and just fees. The success of the railroad has been attained at the most unwarranted discriminations and its effect has been to build up the strong at the expense of the weak. as stated in Document J. This method of success had come to cease because the rich were becoming richer and the poor, poorer. Document L depicts the beneficial aspects of the Interstate Commerce Act, The act to regulate commerce was not passed to injure any interests, but to conserve and protect bringing about great and salutary  measures of improvement. The act has operated directly to increase railway earnings despite initial appearance. The Sherman Antitrust Act was the proceeding measure taken by the Feds. The Senate, being dominated by monopolists as shown in Document M, was forced to pass the act. Actions in Senate were taken in the interest of monopolies instead of the people. This is a Senate of the monopolists by the monopolists, for the monopolists. The act declared all contracts restricting trade to be illegal. This was of importance to the monopolies because trade restrictions would harm them greatly. Contemporary corporations were required to be versatile in the expanding American economy. Individual enterprises fought diligently to dominate economic affairs but the government was obligated to intervene when unjust activity was apparent. The Laissez-Faire attitude was quite popular during this time. However, problems arose when it was in affect. The government instituted the Interstate Commerce Act and the Sherman Antitrust Act to maintain a more balanced economy and make life easier for the poor. The Federal government only intervened in the economy when it was necessary to do so.

Marketing Strategies and Marketing Management Styles

Marketing Strategies and Marketing Management Styles INTRODUCTION: MEANING OF MARKETING AND MARAKETING MANAGEMENT: Marketing as a business function will change with the movement of products and service from the producer to the user. Ability to sell at a profit is the critical test. The marketing system that delivers out high standards of living consists of many large and small companies seeking success. Many factors contribute to making a company successful great strategy, dedicated employees, good information system and excellent implementation. Many peoples minds are stereotyped fixed that large companies operating in highly developed economies use marketing involves with inside outside the Organization Swat Analysis. Any large small scale organization can build in. MARKETING: Marketing has often been described as the as of selling products. But people are surprised when they hear that the most important part of marketing is not selling! Selling is only the tip of the marketing iceberg. Marketing is a societal process by which individuals and groups obtain what they need and want through creating, offering, and freely exchanging products and services of value with others. Marketing is a social and managerial process by which individuals and groups obtain what they need and want through creating and exchanging products and values with others. It is an integrated process through which companies create value for customers and build strong customer relationships in order to capture value fro customers in return. Marketing is used to create the customer, to keep the customer and to satisfy the customer. With the customer as the focus of its activities, it can be concluded that marketing management is one of the major components of business management. The evolution of marketing was caused due to mature markets and overcapacities in the last decades. Companies then shifted the focus from production more to the customer in order to stay profitable. The term marketing concept holds that achieving organizational goals depends on knowing the needs and wants of target markets and delivering the desired satisfactions.[It proposes that in order to satisfy its organizational objectives, an organization should anticipate the needs and wants of consumers and satisfy these more effectively than competitors. MARKETING MANAGEMENT: Marketing is the process of planning and executing the conception, pricing promotion, and distribution on ideas, goods, and services to create exchanges that satisfy individual and organizational goals. Marketing management is a business discipline which is focused on the practical application of marketing techniques and the management of a firms marketing resources and activities. Marketing managers are often responsible for influencing the level, timing, and composition of customer demand accepted definition of the term. In part, this is because the role of a marketing manager can vary significantly based on a business size, corporate culture, and industry context. For example, in a large consumer products company, the marketing manager may act as the overall general manager of his or her assigned product. From this prospect it consists of 5 steps, beginning with the market environment research. After fixing the targets and setting the strategies, they will be realized by the marketing mix in step 4. The last step in the process is the marketing controlling. Marketing management design effective, cost-efficient implementation programs, firms must possess a detailed, objective understanding of their own business and the market in which they operate. In analyzing these issues, the discipline of marketing management often overlaps with the related discipline of strategic planning. Definitions: Market: A market consists of all the potential customers sharing a particular need or want to might be willing and able to engage in exchange to satisfy that need or want. Marketing: The term Marketing has been defined in various ways by different marketing management experts. These definitions can be group in two major categories namely classical or old definitions and modern definitions. Marketing is the performance of business activities that directs the flow of goods and services from produces to consumers or users. AMERICAN MARKETING ASSOCIATION Marketing is social and managerial process by which individuals and group obtain what they need and what through creating, offering and exchanging the products of value with orders. Marketing is defined by the American Marketing Association as the activity, set of institutions, and processes for creating, communicating, delivering, and exchanging offerings that have value for customers, clients, partners, and society at large. The term developed from the original meaning which referred literally to going to a market to buy or sell goods or services. Seen from a systems point of view, sales process engineering views marketing as a set of processes that are interconnected and interdependent with other functions, whose methods can be improved using a variety of relatively new Approaches Marketing Management Marketing management is the process of planning and executing the conception, pricing, promotion and distribution of ideal goods and services to create exchanges that satisfy individual and organizational objectives. What is marketing channel and its work:- Most producers do not sell their products directly to the final users between them stands a set of intermediaries performing a variety of functions. These intermediaries constitute a marketing channel (also called a Trade channel and Distribution channel). Marketing channel are sets interdependent organizations involved in the process of making a product or service available for use or consumption. Marketing channel decisions are among the most critical decisions. The companys prices depend on whether it uses mass merchandisers or high quality boutiques. The firms sales force and advertising decisions dependent on how much training and motivation dealers need. Marketing. Several definitions have been proposed for the term marketing. Each tends to emphasize different issues. Memorizing a definition is unlikely to be useful; ultimately, it makes more sense to thinking of ways to benefit from creating customer value in the most effective way, subject to ethical and other constraints that one may have. The 2006 and 2007 definitions offered by the American Marketing Association are relatively similar, with the 2007 appearing a bit more concise. Note that the definitions make several points: A main objective of marketing is to create customer value. Marketing usually involves an exchange between buyers and sellers or between other parties. Marketing has an impact on the firm, its suppliers, its customers, and others affected by the firms choices. Marketing frequently involves enduring relationships between buyers, sellers, and other parties. Processes involved include creating, communicating, delivering, and exchanging offerings. Delivering customer value: The central idea behind marketing is the idea that a firm or other entity will create something of value to one or more customers who, in turn, are willing to pay enough (or contribute other forms of value) to make the venture worthwhile considering opportunity costs. Value can be created in a number of different ways. Some firms manufacture basic products (e.g., bricks) but provide relatively little value above that. Other firms make products whose tangible value is supplemented by services (e.g., a computer manufacturer provides a computer loaded with software and provides a warranty, technical support, and software updates). It is not necessary for a firm to physically handle a product to add value-e.g., online airline reservation systems add value by compiling information about available flight connections and fares, allowing the customer to buy a ticket, forwarding billing information to the airline, and forwarding reservation information to the customer. It should be noted that value must be examined from the point of view of the customer. Some customer segments value certain product attributes more than others. A very expensive product-relative to others in the category-may, in fact, represent great value to a particular customer segment because the benefits received are seen as even greater than the sacrifice made (usually in terms of money). Some segments have very unique and specific desires, and may value what-to some individuals-may seem a lower quality item-very highly. Some forms of customer value. The marketing process involves ways that value can be created for the customer. Form utility involves the idea that the product is made available to the consumer in some form that is more useful than any commodities that are used to create it. A customer buys a chair, for example, rather than the wood and other components used to create the chair. Thus, the customer benefits from the specialization that allows the manufacturer to more efficiently create a chair than the customer could do him or herself. Place utility refers to the idea that a product made available to the customer at a preferred location is worth more than one at the place of manufacture. It is much more convenient for the customer to be able to buy food items in a supermarket in his or her neighborhood than it is to pick up these from the farmer. Time utility involves the idea of having the product made available when needed by the customer. The customer may buy a turkey a few days before Thanksgiving without having to plan to have it available. Intermediaries take care of the logistics to have the turkeys-which are easily perishable and bulky to store in a freezer-available when customers demand them. Possession utility involves the idea that the consumer can go to one store and obtain a large assortment of goods from different manufacturers during one shopping occasion. Supermarkets combine food and other household items from a number of different suppliers in one place. Certain superstores such as the European hypermarkets and the Wal-Mart super centers combine even more items into one setting. Marketing Strategy: Once the company has obtained an adequate understanding of the customer base and its own competitive position in the industry, marketing managers are able to make key strategic decisions and develop a marketing strategy designed to maximize the revenues and profits of the firm. The selected strategy may aim for any of a variety of specific objectives, including optimizing short-term unit margins, revenue growth, market share, long-term profitability, or other goals. To achieve the desired objectives, marketers typically identify one or more target customer segments which they intend to pursue. Customer segments are often selected as targets because they score highly on two dimensions: The segment is attractive to serve because it is large, growing, makes frequent purchases, is not price sensitive (i.e. is willing to pay high prices), or other factors; and The company has the resources and capabilities to compete for the segments business, can meet their needs better than the competition, and can do so profitably. In fact, a commonly cited definition of marketing is simply meeting needs profitably. Marketing environment: The term marketing environment relates to all of the factors (whether internal, external, direct or indirect) that affects a firms marketing decision-making or planning and is subject of the marketing research. A firms marketing environment consists of two main areas, which are: Macro environment: On the macro environment a firm holds only little control. It consists of a variety of external factors that manifest on a large (or macro) scale. These are typically economic, social, political or technological phenomena. A common method of assessing a firms macro-environment is via a PESTLE (Political, Economic, Social, Technological, Legal, and Ecological) analysis. Within a PESTLE analysis, a firm would analyze national political issues, culture and climate, key macroeconomic conditions, health and indicators (such as economic growth, inflation, unemployment, etc.), social trends/attitudes, and the nature of technologys impact on its society and the business processes within the society. Micro environment: A firm holds a greater amount (though not necessarily total) control of the micro environment. It comprises factors pertinent to the firm itself, or stakeholders closely connected with the firm or company. A firms micro environment typically spans: Customers/consumers, Employees, Suppliers, The Media. By contrast to the macro environment, an organization holds a greater degree of control over these factors. Elements of the environment: The marketing environment involves factors that, for the most part, are beyond the control of the company. Thus, the company must adapt to these factors. It is important to observe how the environment changes so that a firm can adapt its strategies appropriately. Consider these environmental forces: Competition: Competitors often creep in and threaten to take away markets from firms. For example, Japanese auto manufacturers became a serious threat to American car makers in the late 1970s and early 1980s. Similarly, the Lotus Corporation, maker of one of the first commercially successful spreadsheets, soon faced competition from other software firms. Note that while competition may be frustrating for the firm, it is good for consumers. (In fact, we will come back to this point when we consider the legal environment).Note that competition today is increasingly global in scope. It is important to recognize that competition can happen at different levels. At the brand level, two firms compete in providing a very similar product or service. Coca Cola and Pepsi, for example, compete for the cola drink market, and United and American Airlines compete for the passenger air transportation market. Firms also face less direct-but frequently very serious-competition at the product level. For example, cola drinks compete against bottled water. Products or services can serve as substitutes for each other even though they are very different in form. Teleconferencing facilities, for example, are very different from airline passenger transportation, but both can bring together people for a meeting. At the budget level, different products or services provide very different benefits, but buyers have to make choices as to what they will buy when they cannot afford-or are unwilling to spend on-both. For example, a family may decide between buying a new car or a high definition television set. The family may also have to choose between going on a foreign vacation or remodeling its kitchen. Firms, too, may have to make choices. The firm has the cash flow either to remodel its offices or install a more energy efficient climate control system; or the firm can choose either to invest in new product development or in a promotional campaign to increase awareness of its brand among consumers. Marketing mix: In the early 1960s, Professor Neil Borden at Harvard Business School identified a number of company performance actions that can influence the consumer decision to purchase goods or services. Borden suggested that all those actions of the company represented a Marketing Mix. Professor E. Jerome McCarthy, at the Michigan State University in the early 1960s, suggested that the Marketing Mix contained 4 elements Product, price, place and promotion. Product: The product aspects of marketing deal with the specifications of the actual goods or services, and how it relates to the end-users needs and wants. The scope of a product generally includes supporting elements such as warranties, guarantees, and support. Pricing: This refers to the process of setting a price for a product, including discounts. The price need not be monetary; it can simply be what is exchanged for the product or services, e.g. time, energy, or attention. Methods of setting prices optimally are in the domain of pricing science. A number of modes of pricing techniques exist, which span: Elasticities (whether Price Elasticity of Demand, Cross Elasticity of Demand, or Income Elasticity of Demand) Market skimming pricing Market penetration pricing Placement: This refers to how the product gets to the customer; for example, point-of-sale placement or retailing. This third P has also sometimes been called Place, referring to the channel by which a product or service is sold (e.g. online vs. retail), which geographic region or industry, to which segment (young adults, families, business people), etc. also referring to how the environment in which the product is sold in can affect sales. Promotion: This includes advertising, sales promotion, including promotional education, publicity, and personal selling. Branding refers to the various methods of promoting the product, brand, or company. These four elements are often referred to as the marketing mix, which a marketer can use to craft a marketing plan. The four Ps model is most useful when marketing low value consumer products. Industrial products, services, high value consumer products require adjustments to this model. Services marketing must account for the unique nature of services. Definition of Feasibility Studies: A feasibility study looks at the viability of an idea with an emphasis on identifying potential problems and attempts to answer one main question: Will the idea work and should you proceed with it? Before you begin writing your business plan you need to identify how, where, and to whom you intend to sell a service or product. You also need to assess your competition and figure out how much money you need to start your business and keep it running until it is established. Feasibility studies address things like where and how the business will operate. They provide in-depth details about the business to determine if and how it can succeed, and serve as a valuable tool for developing a winning business plan. Important of the feasibility: The information you gather and present in your feasibility study will help you; List in detail all the things you need to make the business work; Identify logistical and other business-related problems and solutions; Develop marketing strategies to convince a bank or investor that your business is worth considering as an investment; Serve as a solid foundation for developing your business plan. Even if you have a great business idea you still have to find a cost-effective way to market and sell your products and services. This is especially important for store-front retail businesses where location could make or break your business. For example, most commercial space leases place restrictions on businesses that can have a dramatic impact on income. A lease may limit business hours/days, parking spaces, restrict the product or service you can offer, and in some cases, even limit the number of customers a business can receive each day. Description of the Business: The product or services to be offered and how they will be delivered. Market Feasibility: Includes a description of the industry, current market, anticipated future market potential, competition, sales projections, potential buyers, etc. Technical Feasibility: Details how you will deliver a product or service (i.e., materials, labor, transportation, where your business will be located, technology needed, etc.). Financial Feasibility: Projects how much start-up capital is needed, sources of capital, returns on investment, etc. Organizational Feasibility: Defines the legal and corporate structure of the business (may also include professional background information about the founders and what skills they can contribute to the business) Market Feasibility: Includes a description of the industry, current market, anticipated future market potential, competition, sales projections, potential buyers, etc. Discusses how the business can succeed. Be honest in your assessment because investors wont just look at your conclusions they will also look at the data and will question your conclusions if they are unrealistic. Feasibility studies contain comprehensive, detailed information about your business structure, your products and services, the market, logistics of how you will actually deliver a product or service, the resources you need to make the business run efficiently, as well as other information about the business. Marketing Feasibility Study: The purpose of the Marketing Feasibility Study is to determine the suitability of this property for profitable development, and to define optimal products and amenities in accordance with projected market demand, and to project sales absorption and annual revenues from development of this property. Things to Include in a market feasibility study include: Description of the Industry Current Market Analysis Competition Anticipated Future Market Potential Potential Buyers and Sources of Revenues Sales Projections NEED FOR THE STUDY: To know about marketing feasibility.

Convenience sampling was used, which is non-probability sampling method Respondents were apprehensive and expressed reservation in giving information on the communication infrastructure and also on the future needs. Research was restricted to time limit. Time is the major constraints, which reduces the sample size. INDUSTRY PROFILE A wind turbine is a machine for converting the kinetic energy in wind into mechanical energy. It the mechanical energy is used directly by machinery, such as a pump or grinding stones, the machine is usually called a windmill. If the mechanical energy is then converted to electricity, the machine is called a wind generator. Wind machines were used for grinding grain in Persia as early as 200 B.C. This type of machine spread throughout the Islamic world and were introduced by Crusaders into Europe in the 13th century. By the 14th century Dutch windmills were in use to drain areas of the Rhine River delta. In Denmark by 1900 there were about 2500 windmills for mechanical loads such as pumps and mills, producing an estimated combined peak power of about 30 MW. The first windmill for electricity production was built in Denmark in 1890. and in 1908 there were 72 wind-driven electric generators from 5 kW. The largest machines were on 24 m towers with four-bladed 23m diameter rotors. By the 1930s windmills were mainly used to generate electricity on farms, mostly in the United States where distribution systems had not yet been installed. In this period, high tensile steel was cheap, and windmills were placed atop pre-fabricated open steel lattice towers. A forerunner of modern horizontal-axis wind generators was in service at Yalta, USSR in 1931. This was a 100 kW generator on a 30 m tower, connected to the local 6.3 kV distribution system. It was reported to have an annual load factor of 32 percent, not much different from current wind machines. In 1941 the worlds first megawatt-size wind turbine was connected to the local electrical distribution system on Grandpas Knob in Castleton, Vermont, USA. This 1.25 MW Smith-Putnam turbine operated for 1100 hours before a blade failed at a known weak point, which had not been reinforced due to war-time material shortages. In the 1940, the U.S. had a rural electrification project that killed the natural market for wind-generated power, since network power distribution provided a farm with more dependable usable energy for a given amount of capital investment. In the 1970s many people began to desire a self-style. Solar cells were too expensive for small-scale electrical generation, so practical people turned to windmills. At first they built ad-hoc designs using wood and automobile parts. Most people discovered that a reliable wind generator is a moderately complex engineering project, well beyond the ability of most romantics. Practical people began to search for and rebuild farm wind-generators from the 1930s. Jacobs wind generators were especially sought after. Later, in the 1980s, California provided tax rebates for ecologically harmless power. These rebates funded the first major use of wind power for utility electricity. These machines, gathered in large wind parks such as at Altamont pass would be considered small and un-economic by modern wind power development standard. In the 1990s, as aesthetics and durability became more important, turbines were placed a top steel or reinforced concrete towers. Small generators are connected to the tower on the ground, and then the tower is raised into position. Larger generators are hoisted into position atop the tower and there is a ladder or staircase inside the tower to allow technicians to reach and maintain the generator. Originally wind generators were built right next to where their power was needed. With the availability of long distance electric power transmission, wind generators are now often on wind farms in windy locations and huge ones are being built offshore, sometimes transmitting power back to land using high voltage submarine cable. Since wind turbines are a renewable means of generating electricity, they are being widely deployed, but their cost is often subsidized by taxpayers, either directly or through renewable energy credits. Much depends on the cost of alternative sources of electricity. Wind generator cost per unit. Power generation from wind has emerged as one of the most successful programmes in the renewable energy sector, and has started making meaningful contributions to the overall power requirements of some States. Energy is a major input for overall socio-economic development. Use of fossil fuels is expected to fuel the economic development process of a majority of the world population during the next two decades. However, at some time during the period 2020-2050, fossil fuels are likely to reach their maximum potential, and their price will become higher than other renewable energy options on account of increasingly constrained production and availability. Therefore, renewable are expected to play a key role in accelerating development and sustainable growth in the second half of the next century, accounting then to 50 to 60% of the total global energy supply. After the creation of a separate Ministry in 1992, special emphasis was given in the Eighth Plan to generation of grid quality power from renewable. The total installed capacity of power from renewables today stands at nearly 1350 MW with contribution from wind power of nearly 1000 MW. Wind power installations worldwide have crossed 8500 MW producing about 14 billion KWh of energy annually. A total capacity of about 5500 MW has been installed in Europe, 1700 MW in USA, and 992 MW in India. India is now the fourth largest wind power generator in the world after Germany, USA and Denmark. The State of the World 1998, a world-watch Institute Report on progress toward a sustainable society, released earlier this year, has noted that renewable energy production in the world is expanding rapidly. Wind generation is the fastest growing energy source in this decade and is expanding at 25% per year. The Report recognizes India as a new Wind Superpower. With declining trend of cost and increase in the scale of wind turbine manufacturing, wind promises to become a major power source globally in the first few decades of the new millennium. MNES (Ministry of Non-conventional Energy Sources) are implementing the worlds largest wind resource assessment programme, which forms the backbone of their wind exploitation efforts. Preliminary estimates indicate a potential of about 20,000 MW. Scientific surveys are being intensified to identify specific viable and potential sites. A recent study undertaken to re-assess the potential, places it at about 45,000 MW. Assuming a grid penetration of 20%, a technical potential of about 9,000 MW is already available for exploitation in the potential States. 160 sites have so far been identified in 13 States. Survey work is in progress in 24 States / UTs. The States of Rajasthan and West Bengal have also shown wind potential recently. Today, we have a wind power installed capacity of 992 MW in the country, out of which about 940 MW is accounted fo

Analysis Of The Impact Of Homelessness On The Health Of Individuals Social Work Essay

Analysis Of The Impact Of Homelessness On The Health Of Individuals Social Work Essay This assignment will be analysing the impact of homelessness on the health of individuals and focusing on the effect homelessness has on a persons mental health and evaluating the response of health providers. The legal definition of homelessness states that an individual as being homeless if they do not have a legal right to occupy accommodation, or if their accommodation is unsuitable to live in. (Homelessness Act 2002) Homelessness is a major social issue especially in urban areas; in 2008 3500 people slept rough in London alone (Broadway 2009). Homelessness is often referred to as sleeping on the streets; this is a common misconception with homelessness existing in many different forms. In reality sleeping on the streets is the most extreme form of homelessness. (Initiatives to tackle homelessness and rough sleeping in London 2008) Homeless people could either be families or single people who do not sleep on the streets but live in alternative accommodation, this is supported by the Government which stated in 2003: the vast majority of homeless people are actually families or single people who are not literally sleeping on the streets but living with relatives and friends or in temporary accommodation (ODPM 2003). The majority of homeless people live in temporary accommodation; these include bed and breakfasts, hotels, shelters, refuges or hostels. These temporary forms of accommodation tend to be poor quality and detrimental to their health and well-being. The results of not having permanent accommodation have a direct link to high stress levels and practical difficulties. Local authorities have a legal duty to provide assistance and advice to people who are legally defined as homeless, or someone who is threatened with homelessness. However, due to the criteria of need not everyone within the legal definition of homelessness necessarily qualifies for accommodation. (Pereira test) A majority of people view homelessness as the result of individuals personal failings in life, and believe that a person chooses to be homeless. Research by the Scottish government found that 48% of the UK public believed that homeless people could find somewhere to live if they tried, and 35% believed that people became homeless, purely on the basis to receive a council house. (Ormston 2006) However the causes of homelessness are a complex interplay between a persons individual circumstances and difficult structural factors, which are outside their control. These problems can build over years, until a point where everything has reached crisis, this is when an individual becomes homeless. Fitzpatrick (2005) explored the positivist and interpretivist schools of thought. These two models are based on different theories about the nature of reality. Positivists believe that knowledge can only be established on what can be experienced or observed. Positivist looks at statistically significant variables for example the lack of social housing and an individuals family problem can lead to someone becoming homeless. However, this cannot include the population as a whole, not all people with family problems in areas where there is a lack of social housing becomes homeless. These people are at an increased risk of becoming homeless, however it does not explain the causes of homelessness. Interpretivism is a term that includes various paradigms, all related with meanings and experiences of human beings. Fitzpatrick (2005) concluded critical realism could explain the reasons why people become homeless. Realists take in a number of factors which could result in someone becoming homeless, for example economic structures, depending on welfare policies and social class can make someone more venerable to homelessness. Realists also consider the supply of affordable housing as an attribute to homelessness. Giddens developed the Structuration Theory which stated that power exists at different points within society for example local authorities, councils and the government. However Giddens states that an individual can have an impact and change things from happening. For example if a childs had substance dependency, the child is more likely to also have substance dependency; this is their predictable fate. Giddens however argues that an individual can have an impact of what happens to them. Similar to the interpretivist approach, Giddens acknowledges that social life is produced and reproduced through action. (Giddens) Post modernists and post structualists argue that there is no one reason for someone becoming homeless. People can become homeless from a range of complex and overlapping reasons; for example, an individual may have alcohol dependencies, which could lead to the end of a relationship, thus being thrown out of the marital home. Solving homelessness is more complex than simply putting a roof over an individual/familys head; work needs to be carried out to solve the underlying issues that resulted in the cause of homelessness in the first instance. These issues may include individual factors, which can consist of alcohol or drug misuse, a lack of social support from friends or family, poor physical or mental health, relationship breakdown through divorce, the demise of a relationship and debts- particularly mortgage or rent arrears. Family background may also be a contributing factor to homelessness; this may include family breakdowns and disputes, physical and sexual abuse in childhood, having parents with alcohol or drug dependencies, or a family history of homelessness. Research by Ravenhill 2000 examined the routes into homelessness found that family conflict was the most common starting point for homelessness. Having an institutional background may also contribute to an individual becoming homeless, these include people who have been in care, in prison or in the armed forces. This statement is backed up by a report commissioned by Shelter 2007 found that 25% of homeless people has spent time in prison. Structural causes of homelessness are social and economic in nature; these are often outside the control of the family or individual concerned. This may include the lack of affordable housing; in England 4.5 million people are on the social housing waiting list (CLG 2009) This number is predicted to rise some 2 million households by 2010 (LGA 2008). As the demand for social housing rises, the supply has decreased by 32%, in 1981 there were 5.5 million, in 2007 there were 3.7 million (CLG 2008). Poverty can also be associated with a structural cause of homelessness, a lack of monetary resources make people more vulnerable to homelessness as they do not have financial stability, for example, unemployment. Poverty is on the increase in the UK in 2007/ 2008 almost 13.5 million people were living in poverty. The housing benefit system can also prevent people recovering from poverty. This system creates barriers for those trying to work (unemployment trap) and people in low paying jobs trying to increae their income (poverty trap). Housing benefit can also block claimants effort to gain new qualifications, as anyone over the age of 18 is not eligible for Housing Benefit if they are studying more than 16 hours per week. These above factors are out of the individuals hands, as they require policy solutions, such as changes in the housing benefit system, and the building of more affordable housing in all local authorities. Applicants for homelessness support from local authorities identified that the three main reasons for having lost their last settled home were; family or friends were unwilling or unable to accommodate them, the loss of assured short hold tenancy and relationship breakdown (Statutory Homelessness Statistics 2008). However these reasons are only factors, which trigger people into seeking assistance, and are not the fundamental reasons that build up in the first place. For many people there is no single event that results in sudden homelessness, however homelessness is due to a number of problems that have built up over time. Homelessness can reoccur in the future as a result of underlying problems and issues remaining unresolved. A study commissioned by Shelter 2007 found that the most frequent reason given for living on the street were, relationship breakdown: 41 per cent, being asked to leave the family home: 28  per cent, drug and alcohol problems: 31 per cent and 28 per cent respectively, leaving prison: 25  per cent, mental health problems: 19 per cent, other: for example, eviction, problems with benefits payments. Interviewees identified two or three factors contributing to their homelessness, which reveal that causes of homelessness cannot be because of one single factor. Crane (1999) argued that unemployment; availability of affordable housing and poverty had little effect on someone becoming homeless. Crane found in her respondents that personal inadequacies such as mental health, emotional distress and coping abilities were more significant as causes of homelessness. The experience of homelessness can have a serious detrimental effect on a persons physical and mental well-being. This is especially true in the case of rough sleepers, who have on average life expectancy of 42 years, compared to the national UK average of 74 for men and 79 for women (Grenier 1996) Poor physical or mental health as well as alcohol or drug dependency are health problems for the entire homeless population, whether they are sleeping on the street, in hostels or in temporary accommodation. Mental ill health, physical disabilities or dependency issues can also trigger or be a part of a chain event that lead to someone becoming homeless. Isolation created by being homeless often means that people find it difficult to access support with services not being in a position to respond to the needs of homeless people. Poor physical health and homelessness often go hand in hand, sleeping on the streets, in squats or in overcrowded accommodation can have a damaging effect on a persons physical well being. In 2006, the National Coalition for the Homeless found that 142 violent acts by non-homeless people against homeless people, 20 of which were fatal. A recent survey of homeless people living in hostels, found that two thirds were suffering from physical health problems which included trench foot, frostbite, bronchitis, pneumonia, wound infections, cardiovascular conditions and liver damage. (St Mungos  2005) Homeless people also lack adequate access to healthcare services. St Mungos research also found that one third of hostel residents who required treatment did not receive any. Research has found that homeless people are 40% times more likely not to be registered with a GP than the general public; research has also found that 55% of homeless people had no contact with a GP in the previous year. (Fountain 2002) Mental ill health is both a cause and also a consequence of homelessness. It is commonly known that there are higher rates of mental health problems in the homeless population. Mental health issues can be caused by the stress associated with being homeless, research by Homeless Link 2009 found that 32% of clients of homelessness services in England have mental health and 14% have personality disorder. Broadway 2009 found that rough sleepers are 35 times more likely to commit suicide than the general population. A report for (Rees 2009) found that the homeless population were twice the levels of common mental health problems, and research found that Psychosis is 4 to 15 times more present in homeless population. Breakdown of a relationship may lead to depression or mental health problems; alcohol may then be used as a coping mechanism to numb the pain. Over two thirds of homeless people reported drug or alcohol use as a reason for first becoming homeless (Crisis 2002). Kemp 2006 also found that those who use drugs are seven times more likely to become homeless than the general population. Homelessness is associated with high levels of stress and mental illness and it is common for those who are traumatised by homeless to seek comfort in alcohol or drug abuse. However not every person who has alcohol or drug dependencies becomes homeless, likewise not every person who is homeless has drug or alcohol problems. However there is a high prevalence of alcohol and drug problems in the homeless population; Homeless Link (2009) found that 39% of clients of homeless services in England have problems with alcohol and 42% has drug problems. Mental health illness is also associated with substance misuse, this is called dual diagnosis. Services for this group are particularly poor, as dependency services have difficulties to cater for people with mental health issues, as do mental health services find it difficult to cater for people with substance misuse. Alcohol dependency, mental ill health and drug dependency are the most common expressed health needs of people who are homeless. There are different types of services aimed at providing homeless people health care. However there are barriers preventing homeless people accessing these services. In order to address these barriers different types of frameworks have been established. The first being the mainstream general practice (intended for the general public) which adopts the extended role in primary care provision. Specialised general practice being the second framework to address barriers in accessing health care specifically for homeless people; this practice only registers homeless people. This type of practice is usually only found in large urban areas where homelessness is greater, this service is therefore unobtainable for homeless people in rural areas. The positive aspect of this framework is that in attempts to integrate homeless people into mainstream general health care, this statement being supported by Lester (2002). However, Wright 2002 argues that specialised general practice can provide a focussed and intensive level of care for homeless people, where integration in to mainstream primary care could be problematic. Wright therefore concluded that this type of framework is a useful tool to provide the initial treatment for homeless people and not the long-term treatment. In essence Specialised general practice offers flexible, high quality and individually tailored responses when treating homeless people with services being open access such as drop in centres. Research by Hagan et al 2001 found a high prevalence of Hepatitis C in injectors who shared injecting equipment. Health promotion for drug dependant homeless people should therefore encourage drug users not to share injecting equipment. Within the UK this has been made possible by setting up a legal framework for distributing sterile injecting equipment Hagen et al 2001. This will make users more aware of the health risks of sharing injecting equipment, and giving homeless people access to health information, and making them aware of the risk factors of sharing needles, spoons and filters. Readily available and accessible health care is required for effective health interventions for homeless people. This involves addressing the barriers in accessing health care and multiagency work in order for homeless people to access the full range of health and social care services. Homeless people face many barriers when accessing health care services; these include the administration of the NHS, which requires a patient having a permanent address before being eligible. Pleace (2000) found that homeless people have often encountered negative attitude and refusal of service by some administrative staff. Due to low self-esteem many homeless people avoid attempting to access these services as they anticipate a hostile environment, which can lead to individual neglecting their health. Numerous homeless people are more concerned with obtaining food and shelter, prior to seeking health care requirements. Evaluations on the services addressing dual-diagnosis, (mental health and substance use, being most frequent) are rare in the UK. Wright et al (2003) concluded that dual diagnosis services were not as competent as single diagnosis services. Health care services that specialise in dual diagnosis will often need specialised accommodation, offering long term sometimes on a permanent basis. In order for Health care services to provide to the needs for homeless people, it needs to adopt a holistic approach, while ensuring user involvement in their care. Ensuring flexible opening times is also a factor which would help meet their need, many people sleeping rough sleep during the day, therefore providing services which are open during the evening would ensure access to homeless people. Many homeless people live in isolation and therefore depend of receiving information about available services through other people in the same situation; the information is therefore not widespread. Homeless people with mental health problems often have difficulties accessing health care services for their needs, therefore resulting with a delay in receiving support or treatment and worsening their condition. It is essential to identify mental health problems and addressing them before a situation reaches crisis. Difficulties in accessing services can be a result of relocating and being situated in different area code, as a result homeless people are therefore not registered with a GP and are reluctant attended different services as they anticipate hostility from staff. In order to ensure that services are accessible to homeless people with mental health problems, services should ensure that mental health services are based within homeless agencies such as shelters and temporary accommodation. These agencies should be open access to ensure homeless people have access to the required resources. There should be dedicated specialist homelessness mental health practitioners visiting homelessness accommodation in order to identify and addressing mental health problems. There is also a requirement for support and training for frontline staff, so that they have the capability and knowledge to identify the symptoms of mental health problems. Frontline agencies in contact with homeless people play a key role in identifying possible mental health problems and then referring them to a specialised team. However, at present not all staff are trained to recognise individuals with mental health problems, for example, homeless people with a withdrawn behaviour can be overlooked, as they do not cause difficulties when staying in temporary accommodation. Homeless people with mental health problems may need support from various different agencies, it is essential for these services to work together to ensure that the individual is receiving the care that they need, and is therefore important for different agencies to share information and conduct joint case conferences. In order for local authorities to meet the mental health needs of homeless people, they must identify what their needs are, in order to identify any gaps in provision. In 2003 all local authorities were required to have a homelessness strategy in place, which should be based on the level and cause of homelessness in their specific area. Local authorities are required too keep strategies under review as homeless people needs vary, ensuring that these strategies are revised every five years. The Department for Communities and Local Government has issued a toolkit in order to assist different local authorities with their review, this emphasises the need to address health issues including mental health (DLG 2006) This is supported by the Homelessness Act (2002) which states that local authorities are obliged to carry out a homelessness review for their district; and formulate and publish a homelessness strategy based on the results of that review. (Homelessness Act 2002) Scottish Government have set Health and Homeless Standards in 2005 which publish health and homelessness standards for NHS boards, its aim was to improve the health of homeless people and support NHS boards in the planning and provision of services for homeless people. In conclusion, this assignment has shown that homelessness has a direct effect on an individuals health; health providers need better funding in order to provide efficient services for homeless people. However in order for local authorities to review their service in order to meet the needs of individuals would be difficult. Measuring how many homeless people exist is complex, many homeless people tend to avoid services, preferring isolation, services available will therefore not meet.

Lucy montgomery :: essays research papers

Lucy Maud Mntgomery The author of the famous Canadian novel ‘ ANNE OF GREEN GABLES’, Lucy Maud Montgomery was born in Clifton (now New London), Prince Edward Island, 30th November, 1874. When she was two, her mother died of tuberculosis. Her father, who was a merchant, remarried, and moved away. Montgomery was raised by her maternal grandparents in Cavendish. The place was isolated and her childhood was not particularly happy: she grew up in an atmosphere of strict discipline and punishment for the slightest reason. She joined her father briefly in Prince Albert, but they soon returned to Prince Edward Island. At an early age Montgomery read widely. She started to write in school and had her first poem published in a local paper at the age of fifteen. In 1895 Montgomery qualified for a teacher’s license at Prince Wales College, Charlottetown. During the 1890’s she worked as a teacher in Bideford and at Lower Bedeque, both on Prince Edward Island. From 1895 to 1896, Montgomery studied literature at Dalhousie University, Halifax. She returned to Cavendish to take care of her grandmother and worked at a local post office. On July 5th, 1911after her grandmother died, Montgomery married the Reverend Ewan MacDonald, to whom she had been secretly engaged since 1906. Prior to her engagement to Macdonald, she had two romantic involvements: an unhappy engagement to her third cousin Edwin Simpson, of Belmont, and a brief but passionate romantic attachment to Herman Leard, of Lower Bedeque. After their marriage, Montgomery and Macdonald moved to Leaskdale, Ontario, where Macdonald was Minister in the Presbyterian Church. She bore three sons, Chester (1912), Hugh (stillborn in 1914), and Stuart (1915). She assisted her husband in his pastoral duties, ran their home, and continued to write best-selling novels as well as short stories and poems. She faithfully recorded entries in her journals and kept up an enormous correspondence with frie nds, family and fans. Maud Montgomery Macdonald did not live on Prince Edward Island again, returning only for vacations. While caring for her grandmother, she wrote the first book of the Anne series. It drew on her girlhood experiences. The idea was based on a notebook entry from 1904, â€Å"Elderly couple applies to orphan asylum for a boy.

The Connections Between Artificial Intelligence and Other Fields Essay

The Connections Between Artificial Intelligence and Other Fields. Abstract Through examples from several fields, this paper will describe the connections between Artificial Intelligence and other areas. Some of these areas make great contributions to AI research, others gain knowledge and technique from that same AI research. This paper will further detail the incredible capacity of AI research to be applied elsewhere to solve similar problems. The goal of this paper is to describe to the reader the impact that AI can create on seemingly unrelated fields. Introduction While Ginsberg defines artificial intelligence as "the enterprise of constructing a physical-symbol system that can reliably pass the Turing test", it is about much more than that (Ginsberg 8). It is about creating a solution where one may not have existed, and eventually programming a machine to do the same. This incredible capacity to find solutions is what AI offers to so many other fields. Artificial intelligence research is not tied to the fields of engineering, psychology, or even computer science. The techniques used in AI have found uses within a large number of other fields. Within the course of this paper, the elements of AI will be outlined, and the way in which they benefit other fields will be explored. Several examples of these fields will be described, and the way in which they incorporate AI will be discussed. Two or three of these fields will be discussed in much greater depth in the second paper, to be completed before December 5th. The reason that artificial intelligence is such a popular field for use by others is that it does not cater to an incredibly specific audience. One of the principle goals of AI research is to help prepare a .. ...ork), and not on theoretical AI. As the technology advances, and more and more lives depend on computers, I can only predict that the reach of AI influences will widen, until it eventually benefits all of us.

Positive and Negative Reinforcement

Positive and Negative Reinforcement Reinforcement is an essential part in identifying and encouraging a certain behavior. In the most classic definition, positive reinforcement is a method of identifying to children which behaviors are acceptable and appropriate and which are not (Sigler, E. & Aamidor, S, 2005). Reinforcement is often given as praise for doing a certain task. As educators, saying â€Å"great job† or a simple word like â€Å"fantastic† are expressed towards students as praise. However, when a student is struggling and praise is given such as â€Å"you are doing so well†, the negative aspects of praise present themselves.The child is aware of the empty praise therefore it may work against the teacher if it is taken as a false praise. So, as educators, we must determine what reinforcements will work with each individual child through experimentation. Also, building a relationship with not just the child, but the parents and all those involved with t he child will be instrumental in developing the proper use of reinforcements and can be helpful in gaining knowledge of certain behaviors. The stronger reinforcements for most children are usually food, candy, or drinks.The durability and effectiveness of a reinforcer can usually be determined best by reinforcing the behavior intermittently or by providing a strong alternative which could interfere with the behavior in question (Ferster, C, 1961). Positive reinforcement is not just about the behaviors of the child but the reaction of the teacher and the adults to certain behaviors. Although a child may attempt to test the boundaries of one’s attention, positive attention does not make a child behave inappropriately (Sigler & Aamidor, 2005). The reinforcing comes from the teacher or adults actions and words.For example, Joshua is an eight-year-old autistic boy who begins to whine and cry every single time the teacher tries to get him to begin a task that he dislikes. Most of t he time Josh only wants to play on the computer, participate in gym, or eat. Each and every time Josh began to break down the staff usually asked him what he wanted or just gave in to what he wanted to do, not even trying to redirect him to the actual task at hand, which his classmates were doing. Joshua would get rewarded with chocolate, potato chips, and even some sympathy hugs from the staff.The behavior became more frequent and the result was the same. By now Joshua knew what he was going to get when he acted out, which was whatever he wanted. However, to change his behavior the staff began to ignore Josh and his outbursts. After a short time of whining and crying Josh threw himself on the floor but the staff still ignored the behavior. He then realized that he was not going to get the same results as he was getting by whining and crying when things didn’t go his way. The teacher then got his attention with another activity and Josh began to take part in the activity.A co uple weeks later, after the same lesson, Josh’s behavior was almost extinguished and slowly that behavior was no longer happening in the classroom. On the other hand, negative reinforcement is the removal of an aversive stimulus to increase a certain behavior. For example, when a student is distracted from his work due to loud music playing, however his work improves when the music is off, then the music being turned off is the reinforce. The difference between positive and negative can sometimes be difficult to acknowledge when there are several consequences and the need of the distinction is debated.The main purpose of giving punishments and rewards is to decrease or increase the behavior of the learner (Dad, Ali, Qadeer Janjua, Shazad, and Khan, 2010). Raul is a student with an emotional disorder and requires a great deal of support to help with his academic goals. Raul is extremely sensitive and becomes very overwhelmed when things don’t go his way. He whines, crie s, and loses control when he feels exhausted from taking instruction. Raul is very intelligent and needs to get verbal praise throughout his day to stay on task. His triggers are usually when he is asked to sit down within the circle during circle time.The behavior is him pulling away, crying, and hitting, trying to escape the actual activity. The maintaining consequence is that the adults let Raul leave the circle. There is not much fight with Raul because all those involved do not want the other students to become distracted. The first prevention is to give Raul some type of choice to coincide with circle time. A visual activity schedule could give him a more clear idea of what he should be doing and what the daily lessons and activities are. Raul will know exactly where he needs to be and what he needs to be doing at that particular time.Also, manipulatives and intermittent praise are other preventions that the teacher can use. Intermittent praise is praised use throughout the ac tivity but not regularly. This type of praise is given to become persistent. The new skills that can be developed are a part of the plan and may be implemented accordingly. Raul may have increased time of engagement, such as a longer duration of sitting within the circle. Raul will say â€Å"all done† when he has completed a task so praise can be given. This will help the adults notice him if he is not given the correct amount of attention.The responses to Raul for sitting longer will also be all positive praise toward Positive reinforcement is something that rewards the individual for an action taken. When students do or exhibit the correct or desired behaviors in school, then rewarding them for this action is what is known as positive reinforcement. There are many examples for these actions. Students that hand in homework on time may be given time near the end of class to put their books away and work on or do something they want to do within the rules of the school.Putting stickers on work well done so the student knows they did the right thing. Giving the class a free day or having fun activities planned for them to do instead of working on a certain day. Giving a weekly or reward to the student who has the best attendance or best behavior in the class. There are many ways to reward students or show them that by using good behavior, they can be rewarded for their actions and this will cause the student to want to do the right thing versus misbehaving in the classroom.References Dad, H. ; Ali, R. ; Qadeer Janjua, M. ; Shazad, S. ; Khan, M.

Bicycle Braking Systems

Bicycle Braking Systems Year 11 Engineering Studies Merewether High School Nathan Dunshea 29/06/2012 Abstract: In this report a comparison of three Braking systems; Calliper, Drum and Disc will be made on a variety of areas including – * * Effectiveness * Performance * Features * Materials * Frictional Components * Difference from comparable car systems An Orthogonal and Pictorial drawing will also be provided on a selected section of one of the braking systems being compared. Introduction: Bicycle Braking systems are a means of which we are able to halt the movement of a bicycle through the expulsion of kinetic energy.The Kinetic potential energy that is present in a moving bicycle is converted in to 3 different forms of energy; heat, sound and light. This is done through the resistance of a wheel to move when a brake applies a frictional force against the spinning movement of a wheel. Three different types of brakes are generally used on bicycles today; the Calliper, Drum an d Disk systems. These three popular braking systems have their own unique set of advantages and disadvantages that persuade the population to purchase them. 2: Calliper Brake Diagram : Calliper Brake Diagram 3: Disc Brake Diagram 3: Disc Brake Diagram 4: Drum Brake Diagram 4: Drum Brake Diagram Procedure: I used the Internet to research pictures, articles and suppliers of Braking systems in order to access the appropriate information needed for this report. Results: Effectiveness, Performance, Features Comparison Effectiveness: 10: Cross-Section of a bicycle drum brake 10: Cross-Section of a bicycle drum brake The effectiveness of these Braking systems will be a measure of their ability to perform over a period of time.It is necessary for these brakes not to only perform well once, but over many instances, including moments of hard excessive braking. In today’s modern bicycle, many things will affect the braking systems ability to be effective. The weather, wear and tear over many uses, as well as the type of braking taking place can all have adverse effects on brakes. Drum brakes are not the most popular style of brake for a bicycle. This could be accredited to their effectiveness over time compared to both calliper brakes and disc brakes. Drum Brakes are typically very heavy, complicated to perform maintenance on and are often subject to brake fading.Break fading can be defined as the loss of braking force able to be exerted by the braking system at any point, and this often happens due to overheating as a result of consistent hard braking. Drum brakes are unable to dissipate heat anywhere near as efficiently as disc brakes as the frictional forces that turn kinetic energy into heat are all enclosed within the drum itself, which is often housed at the hub of the wheel. In fact, many companies have been forced to put warning labels on their hubs to make sure children aren’t unaware of the heat generated, and subsequently burn themselves.This mak es them particularly susceptible to brake fading, something that both disk and calliper brakes don’t have a great problem with. In adverse weather conditions, the drum brake can show of its unique asset both the disc and calliper brake does not have. The Drum brake is fully enclosed, and therefore is not affected by rain, mud and other substances that may impede the frictional force exerted on the wheel. 12: Disc brake to be fitted to a Mountain Bike 12: Disc brake to be fitted to a Mountain Bike Disc Brakes are very popular on Mountain Bikes, which require thick wheels and are often subject to muddy terrain.Because the disc brake is mounted to the hub, a certain clearance from the ground is maintained at all times, generally keeping mud from obstructing the pads and disc. If water is to get stuck under a disc brake’s pad, there are generally holes through which it can quickly escape so to not compromise the friction produced in the system. Touring bikes have been know n to prefer disc brakes to types of calliper brakes, as the long journeys and significant use of brakes would not wear out the rim as they do using a calliper brakes system.The typical Disc Brake system is a very adaptable structure as it can perform better than Calliper Brakes in the mud, rain and snow as the coefficient of friction isn’t as at risk of contaminants disturbing the system. Disc brakes are also less prone to brake fading when subject to long periods of braking pressure, as they are very good at cooling down compared to drum and calliper brakes. A disk brake is also less likely to cause a popped tyre, with the heat not being dissipated directly into the tyre as in calliper brakes. 14: Shimano Bicycle Caliper Brake 14: Shimano Bicycle Caliper BrakeCalliper Brakes are generally the most common of the braking system for the everyday bicycle. Excluding the original design quality of the equipment and materials, calliper brakes are often affected mostly by the moistu re that is on the rim, as that will significantly hinder the ability to stop. Tyre thickness can also pose a problem to the calliper braking system, as the arms will be under greater flexion, thus lessening brake effectiveness. However, the Calliper brake system is effective on the average road bike and is the simplest and easiest to perform maintenance on of all three designs.This system also has a very big ‘mechanical advantage’, meaning very little effort has to be put in by the rider in order to properly apply the brakes. Calliper brakes are also by far the lightest and least expensive, making them popular among non-competitive riders, with most road bikes still come fitted with this system. Performance: The performance of a braking system is based on the raw stopping power and ability for one single use. This comparison will be based purely on stopping power and performance, disregarding things such as; * Weight of system * Weather/Terrain Brake Fading * Heat Dissi pation The Disc Brake is said to have the greatest stopping power, and therefore provides least stopping distance, of all three systems. This means they are often fitted to competitive riders bikes, because they are often going a higher speed and therefore need the greater stopping power that the disc brake provides compared to that of the drum and calliper braking system. In a report By Guy Kesteven for UK organisation ‘What Mountain Bike’, a variety of disc brakes were tested from many different manufacturers to test the power of each system.The test was performed as follows: â€Å"All the brakes were tested with a 180mm rotor and a 50Nm force on the lever (1N is the amount of force required to accelerate 1kg at 1m/s2), with the stock pads. To fully bed in the rotors and pads, the brakes were given 60 one-second pulls at 15km/h, followed by 30 two-second pulls at 20km/h. After a 30-second cooling-down period, the testing began. With the wheel spinning at 30km/h, each brake was applied for three seconds and then left to recover for 10 seconds. This cycle was repeated 15 times. The results were then averaged out to provide a single power rating. – Guy Kesteven; What Mountain Bike. After the test had been completed, the Formula R0 disc braking system had the greatest power of all 33 parts tested. It was found to have a power of 124 Nm when stopping, which is equal to 12. 645 kilogram-force meters. Calliper Brakes have one of the best designs in terms of their Mechanical Advantage. Very little effort has to be put in by the user to have the brakes perform as well as possible. Disc Brakes have an overall stopping power advantage over the general calliper brake, however some versions of the calliper brake have a greater stopping power than the drum brake design.With the huge variety of designs in the field of Calliper Brakes, stopping power can range from quite poor to very high. An example of this stopping power is the test carried out by Mat t Pacocha in the June 2009 edition of Velonews. A group of Bicycle Calliper brakes were to be tested to measure their stopping power: â€Å"This test was performed on a flat, windless road. For each brake, the rider accelerated to 40km/hr then grabbed the brakes — hard — on a pre-determined mark and recorded stopping distance.This test was performed 10 times for each brake, and the stopping distances were averaged. † – Matt Pacocha; Velonews. At the end of the test, the Shimano 7900 dual pivot calliper brake was found to have the greatest braking force, with the shortest stopping distance of 7. 18 metres. It was also found that the average deceleration of the bicycle was 8. 59 m/s2, whilst the greatest deceleration was recorded at 10. 35 m/s2 (Over 1 G-force). Drum Brakes are less powerful than the disc brake, and therefore have a greater stopping distance in normal, controlled conditions.Compared to Calliper brakes it is not clear-cut which has a better stopping distance, as there are many different versions of each type of brake to choose from. However, it is said that the modern drum brake is able to provide a much smoother, more reliable deceleration than the majority of calliper brake systems. Features: Each of these braking systems have their own features which help to enhance the ability to stop the movement of a bicycle. Whilst some of these advantages are purely performance based, others may have features that are cost-effective or maintenance friendly.One of the most important features in the success of the disc brake is its ability to dissipate the heat generated from the frictional forces. Disc brakes are out in the open air with a large surface area, meaning the cooling process happens more quickly and efficiently. Another important, yet perhaps underestimated feature of the disc brake is it’s positioning. Disc brakes are well away from the tyres and ground, thus creating distance between the braking system and m ud, dirt and other potential environmental interferences.Drum brakes however, are certainly the best in resisting those environmental factors. As the braking mechanism itself is housed within a shell of sorts, no amount of weather can have an adverse effect on the ability of the drum brake to perform its task. Once installed, drum brake system is also very low maintenance, and often doesn’t have to be managed again until a new wheel is needed. Despite this, Drum Brakes can be a hassle if maintenance must occur, as they can be difficult to access because of the shell it is housed in. Calliper Brakes are generally the cheapest of the three designs available.As they are often mounted to the bicycle at one single point, accessing the brake pads and cables is made much easier than the other systems. Another feature that is useful on the majority of road bikes with calliper brake systems is the quick release mechanism. This feature is designed as to loosen the brake system enough s o the wheel can be removed without having to mess around with loosening brake cables as well. Materials used for construction and frictional components Brake Pads are perhaps the most important part of both the Disc and Calliper braking systems.The brake pad is generally made from a product that possesses a moderately high coefficient of friction, but also depends on the materials ability to absorb and dissipate the heat produced in the process of braking. If these criteria can be met without having a negative impact on overall braking performance, an appropriate material has been found. In years gone by, an asbestos based compound was the most common material from which brake pads would be made, however because of the toxic nature of asbestos that practise no longer allowed. The modern bicycle Brake Pad is enerally made from rubber compound. The rims on bicycles directly affect the performance of the Calliper braking Systems. Some bike rims today are made from an aluminium alloy, w hich provide a coefficient of friction when in contact with the rubber composite of the brake pads of approximately 0. 4. Other materials, such as various Carbon steels, have recently become more popular as they are light and aerodynamic. However, they do not provide a very good frictional force between the everyday brake pad, and so other materials are often preferred by the everyday cyclist.Calliper brake systems also have brake cables that transfer the motion actuated by the rider from the brake lever to the braking system itself. These brake cables are made from thin wire steel that has been braided together to improve its tensile strength and ability to perform. The Disc in the Disk brake system is an integral part of the bicycles stopping power. The Brake pad (rubber composite) must have a high enough coefficient of friction when applied to the disc to halt movement with damaging the surface.To provide this, the disc is made from metal, with stainless steel being popular among mountain bikes. A brake drum has an outer shell in which the braking system itself is contained. This outer shell is subject to weathering from the outside and heat from within. With this in mid, cast-iron is generally the material chosen as it can cope with these two burdens other materials could falter under. The shoes of the Drum brake are the parts that push outwards to produce the frictional forces needed in the brake design.These brake shoes are generally made when two pieces of sheet steel are welded together. After they are welded together, the frictional material known as brake lining is connected on to the sheet steel with either adhesive resin or other means such as a rivet. It is also important to remember that the rubber composite of bicycle tyres also has frictional forces acting from the material it is rolling on. For instance, if a cyclist was riding along a concrete surface, the coefficient of friction would be 0. 8, much higher than that of rubber or brake lining to metal (0. ). Thankfully, the relatively light weight of the human body – compared to the force exerted by our mechanical braking systems – allows us to still move along these surfaces. (FF = ? RN) How they differ from comparable car systems On most bicycles, the braking systems installed will often be very simplistic and just there to do the job. Most will have the same type of brake on both front and back wheel, with the braking of the bike mostly relying on human action with levers and cables, as well as the mechanical advantage some of these designs provide.However, when upgrading these systems to work on a much heavier vehicle such as a car, many things can change. It is not uncommon to have different types of brakes on the front and back set of wheels, and hydraulics become a very important part of stopping your car. In today’s modern designs, at least one set Disk Brakes are fitted to almost every car on the road. Disk Brakes are the most effective type of braking system that we could fit to our cars, however, it is still common for the front brakes to be disk, but the rear to be drum brakes.Drum brakes can be used as the parking brake, and by fitting them to the rear of the car, companies can save money by not having to install another braking system. The Disc Brake in a car is obviously in a much larger scale than that of a bicycle. Despite this, the two systems are very similar in the basic design concept. Strength of this part however, must be much greater when installed in an Automobile. Winnard & Sons Ltd, a company based in the UK that deals with commercial vehicle braking components, has a guideline to the tensile strength on the brake contact surfaces of their products. Guideline tensile strength on test pieces machined from brake drum/disc contact faces: – 241 N/mm2 European Requirement minimum – 35,000 psi Amercian Requirement minimum† – Winnard & Sons Ltd: Brake Disc and Brake Drum Material S pecification The materials used in the brake pads of both the disk and calliper brakes are different when they are made for cars. When halting the momentum of a car, the brake pad is put under a much greater force than when stopping a bicycle. This is due to a number of things, including the speed at which the car is travelling and the mass of the vehicle, both of which are generally higher in cars.The metals used are usually steel, copper or brass fibres, as well as a mixture of many different composites including – graphite, iron oxide, glass fibres, phosphate and rubber – that are bonded together with a resin of phenol formaldehyde. The metals that are added help to increase life span by improving the ability of the compound to dissipate heat at high speeds. The complexity of all three designs is greatly heightened when moving from bicycle to motor vehicle. One aspect of Motor Vehicle braking that creates extra pressure is the hydraulic action of the brakes.Hydrauli cs rely on brake fluid, typically containing ethylene glycol, to transfer pressure from the controlling unit to the brake mechanism. In a motor vehicle, drum brakes often serve a specific purpose that they would be useless for when installed on a bicycle – the park brake. As I stated earlier, these Drum brakes are fitted to the rear wheels and can save companies significant amounts of money by not having to install a completely separate parking brake. As this asset of an emergency brake is vital to a larger system, not only are they more common in cars, but they must also be bigger and exert a greater force.These three types of braking systems hold the same principles when applied to a greater size vehicle in a motor car, however many things must change to accommodate these increased forces. Conclusion: Each of these three braking systems are often used by a specific type of bicycle with a specific need. An example of this is Disc brakes being preferred by those who ride eith er Mountain or Touring bikes. As shown by the two field tests referenced in this report, completed by Velonews and What Mountain Bike, both Calliper brakes and disc brakes both have a very big potential to have immense stopping power.But to have that stopping power, the proper materials with appropriate frictional forces would have had to been in place. At the absolute top of the line models, every little detail is considered, i. e. : * * Weight * Frictional Forces * Materials * Angle * Type of System It was also discovered that as we transition from bicycle to car braking systems, many things must be altered. Although the basic engineering principles are often the same, there are many variables that are altered to improve to braking systems to cope with the extra forces exerted by a motor vehicle.For example, the change in materials of brake pads to accommodate the much more intense levels of heat being produced when heavy braking is taking place. I believe this report reveals that the braking system you own can make a big difference on effectiveness and performance. The features, materials used and frictional forces in play can all be positive or negative depending on the type of riding taking place. Recommendations: I recommend selecting one of these three types of braking systems based on what their use in the long run will be.If you plan to use the bike for competitive purposes when increased stopping power is necessary, I would suggest purchasing a Disc brake system. However, if the bike is simply for leisure, perhaps the more cost effective Calliper Brake system would better suit. If you are planning to ride in muddy areas where the possibility of substances interfering with the frictional forces throughout the braking system, the fully enclosed drum brake system could be the appropriate option. However, if you wish to simply have the greatest overall stopping power, I would recommend a Disk Brake system be installed. The most mportant thing to remember is that every situation is unique, and to do research in order to attain the correct brake for your needs.
