Create a profile of a leader (Martin L. King). Create an assignment that investigates key leadership practices and relationships - Essay Example He spoke to other leaders and shared with them knowledge that he was able to pull into his own public leadership in order to enhance the effectiveness of his movement. The challenges that he faced were met with the preparation that he had made towards becoming an effective leader, although he had expected to lead a church rather than a nation. King was a well educated man who focused a portion of his education on the oratory aspects of leadership. He learned to become an effective speaker, exploiting his own natural ability to deliver a public message. His core method of leadership was in focusing his charismatic talents so that his followers believed in his message. Biography of King Martin Luther King Jr. was born on January 14, 1929 to Reverend Martin Luther King and his wife Alberta in Atlanta, Georgia within the United States. At the age of fifteen, Martin Luther King Jr. entered Morehouse College in Atlanta before graduating from high school where he studied sociology. At the a ge of nineteen in 1948 he finished his undergraduate Bachelor of Arts degree in sociology and became a minister. In 1951, King graduated with a second Bachelor of Arts degree in divinity before going on to study systematic theology as a graduate student at Boston University. He married Coretta Scott in Marion, Alabama in 1953 before being appointed a minister as a pastor to Dextor Avenue Baptist Church in Montgomery Alabama. In 1955, King received his doctorate in systemic theology from Boston University, giving him the title of Dr. Martin Luther King Jr (Bruns, 2006, p. xii). King rose to national prominence when he was made the spokesperson for the Montgomery bus boycott. The boycott started 1955 when Rosa Parks refused to move to the back of the bus, a white bus driving insisting that she make the move as African Americans were segregated from seating at the front which was reserved for Caucasians. The boycott lasted for more than a year, financially crippling the public transpor tation of the city as African American users were the larger portion of the public transportation using public. The organisation that was created to support the movement was the Montgomery Improvement Association of which King was elected president. In 1956, the Supreme Court ruled that segregation was not a legal and this victory provided King a platform of success from which to further his intentions to abolish segregation policies and discrimination in the United States. In January of 1957, King formed the Southern Christian Leadership Conference in order to provide a resource for organized protests for civil rights (Bruns, 2006, p. xii). At this point, King’s career begins to move at a quick pace, his public accomplishments adding up to a powerful momentum as a leader, his choices promoting larger and larger successes that were filled with activity and progress towards civil rights. He was given audience by prominent leaders and taken seriously for the strength of the num bers of his followers, creating a movement that would eventually find success in abolishing legal separation between the rights of Caucasians and the rights of African Americans. He met with President Eisenhower in June of 1958 and Mahatma Gandhi in

Culture and Diversity in Decision Making Essay Example for Free

Culture and Diversity in Decision Making Essay The definition of the mission and goals of the enterprise is the foundation for any business. Mission is the answer to the question, what is the activity of the company is and what it intends to do. Procter Gamble has a pretty clear statement: We are there to improve your life After the mission, the organization needs to define the purpose. In this case, the goal to produce goods and services of the highest quality and customer value that improve the lives of todays and future generations around the world. Consumers help to take a leading position in terms of sales, to ensure the prosperity of the business that contributes to the well-being of employees and shareholders, as well as those areas where employees live and work. The goal unites workers for the common cause of the growth strategy. It has great potential due to a simple idea to improve on daily lives of consumers around the world. It is this setting allows P ; G to achieve maximum full growth. So, from the above we can highlight the important goals of the company: A. Providing quality products, customer focus; B. Creating a stable, growing company. 3. About the P;G company’s culture signs. The company provides a certain amount of self – dependence divisional governance structure that provides greater flexibility and faster response to changes in the business environment compared to the linear and linear- staff. Managerial responsibility for the activities of the company both in the domestic and foreign market is shared between them. This type of structure combines centralized coordination and control of centrally managed. Key figures in the management of an organization with a divisional structure not heads of functional units, and the managers in charge of the production department, the so-called divisions. The company groups are formed by categories, each of which includes experts in marketing, sales and advertising. These narrow specialists provide each its part under the direct control of the manager category. The level of the manager is very high. 4. Factors that caused the organization to embody this particular culture. P;G company has been working toward keeping its reputation and standards in all field. Since it was established, P;G has built rich heritage of touching consumers’ lives with brands that make life a little better every day. Here is to motto says â€Å"Do the Right Thing – For each other† The culture of the company is based on the basic moral and ethical values leadership, striving for the victory, the hosts respect, honesty and trust. These values are not something abstract they define the actions of the company. 5. What type of leader would be the best? In my opinion there are many reasons that this leader structure will be effective. First, as part of a huge company it managed to create an environment where every employee is interesting to work with. The responsibility of each employee, including the manager is the main driving force effectiveness. And this is the result of the constructed system of management, whose main task is to create conditions for the moral and material interests of each employee. Second, the complexity of management and collective management style in this company is proposed to use a single control method. The management system is structured in a complex of  functional subsystems. That is, they include highlights key subsystems within each of which formed goals, measurable indicators are introduced, developed a system for calculating them are formalized standards, business processes and organizational procedures. Disconnected from the management of the business functions of the companys managers are moving to a collective system of integrated management of business functions. 6. Imagine that there is a decline in the demand of products. What the change in culture would be need to be in response to this situation. I think company’s CEO should work with the sale’s department. Look up their regular planning and control of the department and its employees, hiring, selection and adaptation of staff; employee motivation, training, exchange of experience, the general debriefing, evaluation of the department, the calculation of cost of sales, cost of sales regulation, evaluation of individual performance of employees. In one word they have to find out their mistake and fix it, because without a reason demand not decreasing itself.

Mental Health Issues in Parents: Service Provisions

Mental Health Issues in Parents: Service Provisions Provide a critical evaluation of current methods of working and service user provisions in the area of parents with a mental health problem, drawing upon developing knowledge and research. Introduction In this thesis we discuss the role of parenting, the responsibilities that are involved and the issues of mental health problems in parents. We draw upon existing knowledge and research to understand mental health problems and psychological complications of parents and discuss health and social policies that are related to current methods of working for such parents within social work. Several research studies, legislative reports and health policies are discussed and we provide a critical evaluation of the provisions, current research materials available and issues regarding mental health and psychological problems of parents and service user provisions. In 1998, the Department of Health emphasised on the programme of Modernising Mental Health Services, with three key aims: Safe services to protect the public and provide effective care for those with mental illness at the time they need it Sound services to ensure that patients and service users have access to the full range of services which they need Supportive services working with patients and service users, their families and carers to build healthier communities. (See DoH, 1998) Service User Provisions and Mental Health Studies and Approaches Among the service provisions available to parents with mental health needs, the programme of the National Service Frameworks (NSF) is part of the Government agenda to improve quality and reduce any unacceptable variations in health and social services National Service Frameworks by the Department of Health, cover mental health issues and coronary disease the significant reasons for causing disability and ill health among the adult population in UK. The NSF frameworks address the mental health needs of working age adults and parents and set out the national standards of care and support, the national service models, local action, and national underpinning programmes for implementation and a series of national milestones and performance indicators to measure progress in this sector. National health standards are set out in five areas including mental health promotion; primary care and access to services; effective services for people with severe mental illness; carers of people with me ntal health problems; and reduction of suicides. This applies to tackling mental health problems in parents and provisions for access to care. The National Service Framework for mental health concentrates on the mental health needs of working age adults up to 65, and covers health promotion, assessment and diagnosis, treatment, rehabilitation and care, and also encompasses primary and specialist care for these individuals. Adult Placement schemes are available for these individuals who are provided with carers, supported living, home based care and day services and extended family support from the NHS and NIMHE. Mental Health crisis intervention services with rehabilitation, counselling and psychotherapy are also provided by the Health authorities. Several studies discuss the process and value of working with parents when their child or children are being treated with individual psychotherapy (see Robinson et al, 2005). A psychoanalytic understanding of the parents’ perspectives in seeing a mentally ill child and the psychological problems of the parents themselves are considered. The issues discussed have a broader applicability in other aspects and approaches of child and adolescent mental health practice (Zubrick et al, 2005). The central issues are interweaving the knowledge of family processes, child development and psychopathology and the uses of the understanding of transference and counter transference as psychoanalytic concepts. The aspects of the work which constitute child guidance are considered psychotherapeutic as it relates to parental psychopathology. To explore and define the boundaries between psychological process of child and parents, the psychotherapy of parenthood may be analysed and implications of parental psychotherapy can be considered along with childrens problems and issues. Flouri (2005) reviews the evidence of the role of childhood adversities, family structure and issues of parenting in determining youth suicidal behaviour and Flouri emphasises that suicide research could benefit from investigating whether proper parenting can protect suicidal behaviour in young people who are vulnerable and at risks. The operationalization of non optimal parenting has often been considered as a risk factor for adolescent suicidal behaviour and influencing and identifying pathways of influence has been a major target. The measures of reducing suicidal risks in the vulnerable populations also tend to focus on parents with weak material and social resources, mental health problems and few networks, low social and emotional support, and high-risk children. The identification of causative factors relating parent mental condition an parental status might be beneficial in preventing youth suicidal behaviours as measures could be taken from a broad social perspective. Citing one of the case studies, Derisley et al (2005) have attempted psychotherapy of parenthood and have used a study to compare mental health, coping and family functioning in parents of young people with obsessive-compulsive disorder (OCD), anxiety disorders, and no known mental health problems. For the methods, 28 parents of young people with OCD, anxiety disorders (N = 28), and no known mental health problems (N = 62), the three different categories of people, all completed Brief Symptom Inventory (Derogatis, 1993), the Coping Responses Inventory (Moos, 1990), and the McMaster family assessment device (Epstein, Baldwin, Bishop, 1983). The results indicated that parents of children with OCD and anxiety disorders had poorer mental health and used more avoidant coping methods than parents of non-clinical and mentally stable children. The results also indicated that there were no significant group differences a measured in three groups in family-functioning. This suggested that the re are basic similarities across parents of clinically referred children and active parental involvement in the treatment of OCD in young people can actually trigger or facilitate the cure and treatment of such young people. Research shows that Black and Minority communities are more likely to suffer from inequalities in access to mental health services, they also report inequalities in their experience of services for mental health care, and they also tend to have more problems and complaints with the outcome of these services. For instance, the Department of Health points out those BME patients are significantly more likely to be detained compulsorily or diagnosed with schizophrenia in mental health situations. The mental health scenario and care provided to minority communities have a direct impact on anti oppressive and anti discriminatory practice. The Department of Health, and the NHS is developing a comprehensive programme of work to tackle inequalities of service provisions to mentally ill patients. In the area of service user provisions for mental health care and support, with an aim to promote anti discriminatory and anti-oppressive practices, the Department of health has identified a strategy for improving mental health services for black and minority ethnic communities in England. Community development workers or social workers are appointed to enhance the capacity within minority ethnic groups, especially adults and parents in dealing with the burden of mental ill health and tackling the inequalities inherent in the services provided. These Community Development Workers contribute to: (source: NIMHE, 2005) Seeking out the strengths and capabilities within particular communities around mental health and the resources available to individuals suffering from mental illness Enabling mental health organisations to bridge the gap between Western models of care and the values and norms of the community they serve Supporting community groups and networks, directing them to resources that are available and funding as appropriate Facilitating community participation and ownership of parents/adults in mental health provision and in combating health inequalities. For provisions of quality services, improved partnership/collaborative work between the NHS, local authorities, prisons, residential homes and the probation services are also required for service development and the care of service users, especially for individuals with severe mental illness. In a study by Hart et al (2005), the implications of user involvement are studied that address the views of clients and their parents on service user delivery in a specialist Child and Adolescent Mental Health Service (CAMHS) serving a population of 250,000.the study explores the complexities inherent in childrens services when parents are integral or involved significantly to different modes of treatment. In the study concerned, 27 teenage clients, 11 boys and 16 girls were recruited from CAMHS and 30 parents were also consulted and they were all from different socioeconomic backgrounds. A series of structured interactive techniques were used by focus groups who also conducted home visits to get interview data. the data was then subject to qualitative analysis and descriptive statistics were generated from interview data and focus groups information. From these data the three issues that were used to describe service user provisions are the core values implicated in establishing a t herapeutic alliance, the style of therapy, and mode of practice with the inclusion of family members. Style of therapy and core therapeutic skills of service providers have been given fundamental importance and Hart et al provided a model of organisational user involvement with a model of therapeutic user involvement for use in negotiating modes of practice with the service user especially in case of mental health practice. The study was thus collaboration between service users, health professionals and researchers and explored different themes of therapy and complexities inherent in childrens services as well as role of parents in mental health care. In fact provisions of parent led self help group and therapeutic approaches are important for achievement of attuned practice. The skills of staff working in adult mental health and child welfare, those that benefit mentally ill parents and their children are recognised by effective collaboration and development of co-ordinated service provision. Health services and local authority staff, as well as workers in education and the voluntary sectors are required to understand the necessities of service provisions. This involves, foundation knowledge, working together and assessment, planning and intervention for mental health care. The attitude of service providers is important and a study by Rasaratnam et al (2004) investigates the influence of attitudes of carers of people with intellectual disability (ID) towards giving medication. In the study 93 carers of service users who were attending an outpatient’s clinic (Harrow Learning Disability service) were interviewed, and the ratings scale used for measures was the RAMS (Rating of Attitude to Medication Scale) interview schedule. The results indicated a single association between relationships of the carer to the service user and overall positive or negative attitude towards medication was also studied. The study found that a disproportionate number of parents have expressed negative attitude in comparison with professional carers (46% vs. 11%) towards medication. the study suggests that standards of compliance with medication needs to be emphasised and researched on especially in case of family carers of mental health problems. Psychiatric disorders se em to have a stigma associated and providing medication for mental illness is still considered unacceptable. The family carers attitude to mental health problems and general mental illness may be shaped by such social and psychological factors. All these issues seem to be important in determining the kind of medication a psychiatric patient should have. In a study by Evans et al (1994), the All-Wales Mental Handicap Strategy (AWS) has promised not just governmental leadership and emphasis on the area of mental health service provisions but also availability of resources for developing community based residential, domiciliary, respite, day-care and professional services for people with mental handicaps and their families. Thus the strategy aims at providing the best for mentally ill people to experience community life. For the study a sample of people with mental handicaps was used to track changes in mental health services received, in professional input, the number of community activities pursued, and the size and range of individuals social networks and involvement in individual planning and the impact of health care strategies. There was a decrease in the proportion of patients living with parents and an increase in those living independently or in another family situation although private residence and serviced residence were bo th equally used for living purposes. Residential service associated with care facilities were also noted and there was marked preference for family based care. Family support services in the form of family aides and short-term care increased significantly, and day service also diversified. The health strategy as followed by the AWS seems to have brought individuals with mental health problems in greater contact with other members of the community although there was no difference in people friendship networks or extent and nature of associations. Yet the service provisions an family and user experiences were found to be in accordance with the direction and goals set by the AWS yet changes are still required and the a new patterns of services have been identified as necessary. The authors point out at the end of the analysis that the mental handicaps do conform to the guiding principles of AWS health strategy and its implications can be significant. If this study is extrapolated to understand the dynamics of the working and provisions for the service user in the contemporary mental health scenario, we can learn several lessons and identify several new provisions that may work with mentally ill patients. Providing a well integrated community network and service provisions at home as well as making resources available to the mentally ill patients either in their residential places or in the community or even at health and clinical settings could be major priorities of any health care strategy. The AWS strategy can thus be a blueprint or a primer for further modern health strategies and provides us with an opportunity for critical appraisal of service provisions that can be made available to mentally ill individuals in need of special care and support. There are however several issues that need to be considered as important in a critical evaluation of service user provisions for mentally ill patients. One of these issues involves improvement of the quality of information about clients referred to a community mental health team for referral purposes. For improved services to clients, improved information is also necessary and new ways of devising this quick availability of information should be encouraged. The second recommendation for improving service provisions involves following clinical guidelines. Michie and Lester (2005) determine whether writing or written clinical guideline recommendations in behaviourally specified plain English language can increase the likelihood of their implementation by service users or the patients. Following clinical guidelines, medication or therapy procedures is an important aspect of treatment and improvement of service user provisions can be made by stronger emphasis and written specification of approved and recommended guidelines. A evaluation of behavioural outcome and the inclination of following these guidelines should also be studied. Using and providing specialist service as in specialist educational intervention for acute inpatient mental health nursing staff and service user views in this regard have been studied. Richards et al (2005) evaluated the impact of an innovative 18-day educational intervention for acute ward-based mental healthcare nursing staff on reported quality of nursing care and on service user views of care using the educational intervention. The quality of inpatient mental health care for people with acute psychiatric problems has remained questionable and several studies have suggested that specialist educational courses and nursing interventions are needed to improve these services. An integration of health and social service care provisions and also day care for mental health patients have been emphasised considering social networks and care needs of the users. Increasing integration of health care and social services requires understanding the difference between health service day hospitals and social service day centres. A study by Catty et al (2005) has suggested that day centre clients had much larger social networks, including a three-fold difference in total contacts and two-fold difference in confidants, but had more needs for care, particularly relating to psychological distress. Our final recommendation for service user care for mental health patients and parents in a mentally ill home ambience is greater involvement of service users in mental health service planning and evaluation. Thornicroft and Tansella (2005) emphasise that service user involvement in the planning and provision of mental health services has been growing in recent years especially in areas where institutional service provision has been changed to a more community-orientated model of care. Recent studies have shown that during mental health crises, joint crisis plans by health providers and service users can significantly reduce the use of compulsory admission during crises. Conclusion: In this essay we provided a critical analysis of the provisions and policies provided by social services and health care services and evaluated the need for certain practices in providing quality service to service users with mental health needs.

Non-Voluntary Euthanasia: The Future of Euthanasia Essay -- Euthanasia

Non-Voluntary Euthanasia: The Future of Euthanasia      Ã‚  Ã‚   Non-voluntary euthanasia seems to be the natural direction in which euthanasia practice evolves. In the Netherlands at the present time, there is a fear on the part of the aged, about being taken to the hospital - where the doctor may have the last word about life and death. This essay digs into this evolutionary process of voluntary euthanasia evolving into the non-voluntary type.    Advocates of legalised euthanasia almost always insist that they only want voluntary euthanasia (VE) - a they say they are as opposed to the taking of life without the subject's knowledge or consent, that is, non-voluntary euthanasia (NVE), as anyone else. Some do extend their advocacy to some examples of NVE, such as seriously deformed newborns, [1] where consent would not be possible, but this is not usual. It is widely accepted that sufficient protection against the unwanted extension of VE to NVE would be ensured by the inclusion of appropriate legal safeguards.    As safeguards, clauses are proposed that would require the doctor to be satisfied that the patient's request was freely made and sufficiently informed, that there was no psychological abnormality such as depression, and possibly by requiring psychiatric consultation, that more than one doctor be involved in the decision that it was medically appropriate to take life in the circumstances, and that there be adequate documentation. It is also common to find lawyers who declare that such laws would be feasible to devise, though it is less common to find actual draft laws published for discussion. In one sense, those lawyers are correct when they say such law would be possible - but they stop short of addressing t... ...thout explicit request of patient.

Five Forces Framework Essay

Porter’s Five Forces Model is a model that analyzes an industry to help develop a business strategy. The model uses five forces that have been identified to categorize an industry as intensely competitive or not competitive at all and this will then determine the attractiveness of the market.There are many features of an industry in which a company competes that determines the level of competition it will face and the profits it will get. The most famous classification was done by Michael Porter, known as Porters Five Forces framework which can help a company determine its potential profits by looking at five sources of competitive pressure. The five sources of competition are: 1. Threat of new entrant 2. Threat of substitutes 3. Rivalry among existing competitors 4. Bargaining power of suppliers 5. Bargaining power of buyers. Porter’s Five Forces In particular, we will focus on three different industries; We will start analyzing the five forces in the smartphone industry and then we will continue dealing with the personal computer industry and finally we will present digital music portable industry. SMARTPHONE Industry: In general the smartphone market is rapidly changing, with constant product introductions. It is characterized by quickly evolving technology and designs, short product life cycles, aggressive pricing, rapid imitation of product and technological advancements, and highly price sensitive consumers. Self-elasticity and cross-elasticity are high. No one firm in the market has sufficient market share to control prices, resulting is strong rivalry and competitive pricing. 1. Threat of new entrant: The barriers to entry are high due to the existence of patents, high fixed costs and economies of scale, regulation, and brand loyalty. The individual market participants engage in attempts at product differentiation, some being more  successful than others. The standout is Apple, which has successfully differentiated its iPhone, and stands a good chance of maintaining that differentiation due to its closed and all-inclusive model or development and use.Barriers to entry in the smartphone market are relatively high, but the rapid growth of the market is providing opportunities despite this. There are significant fixed costs associated with smartphone manufacturing. While most firms have the hardware of the phones manufactured overseas by foreign companies, the costs of developing the research and engineering personnel to design and test the smartphone and software can be prohibitively expensive for an entering firm. These fixed costs include not just the cost of the manpower, intellectual knowhow, intellectual property, computers, test equipment, prototyping devices and supplier and manufacturer contracts, but also the time necessary to develop all of these. Because the industry moves so quickly, an entering firm would either have to enter with existing resources targeting the smartphone market, or it would have to have another significant competitive. Moreover consumer will face an high switching costs if they decide to change their products, as a result of the fidelity every brand put on its product. Because all these reasons smartphone industry is extremely difficult to enter. As a result the threat of new competition is low. Smartphone production needs huge number of money and high technology. Even if established the company, it is impossible for new brand to compete with big company like Apple and Samsung. 2. Threat of substitutes : As a result of the high barrier to entry, to build and launch a substitute product is a hard work. Thus Threat of substitute is low. It’s extremely difficult to enter Smartphone production; because this industry base on high technology. As a result, it’s very hard to invent the substitute to replace smartphone with low price and more power function. 3. Rivalry among existing competitors:With rapid innovation necessary for a rapidly changing market, where customers are very price conscious, rivalry among firms in the smartphone market is fierce. Firms in the smartphone market actively work to adopt the successful ideas and technology of their competitors. This has been the trend with large touch screens, touch friendly operating systems, embedded cameras, and availability of an easy to  use app store, among other things. As consumers are more and more driven to purchase by the features that are available on the smartphone, there is a constant rivalry among firms to match each other on features. There is also an effort to stifle each other’s efforts to develop those technologies through obtaining of patents and filing lawsuits seeking injunctions and trade restrictions. No particular firm in the market has a significant amount of market power; every firm is vying for a greater piece of the pie. This has resulted in drivin g down of smartphone prices and relative price parity for flagship smartphones from each major firm. Firms are heavily involved in price discrimination, pricing their phones differently based on the sale outlet. Smartphones sold through retailers are frequently cheaper than those sold through network service providers. The one exception to this is Apple. Apple maintains price equivalency no matter the outlet, and the prices it charges for its smartphones is in many cases much higher than its competitors. Because Apple has been able to do this, its smartphone sales are reportedly highly profitable, while smartphone sales for Motorola have not been profitable at all. Rivalry also comes from outside the manufacturers’ market as other firms try to cash in on the smartphone profits. Google open sourced the Android OS so that it could find revenue from sales of apps and ads through the smartphones that run the OS. This cuts directly into Apple’s effort to become the dominant player in the smartphone manufacturer market, changing the nature of the market significantly. Such changes are likely to continue as other firms attempt to enter the market. Therefore, threat of substitute might have two factors (price and performance) which allows customer to switch the product as well as willingness of buyers to switch. Threat of substitute can be reduced as much as buyers become loyal to the products. To give an example, Apple has been able to create an â€Å"ecosystem†. People buy iPhone for standard, apps and other Apple’s product for upgradeability and stability which gives customer the ability to transfer knowledge and apps among devices 4. Bargaining power of suppliers: Bargaining is very high; Smartphones’ producers have to deal with two different categories of supplier: the hardware producers and the software. Because smartphone production market is not easy to enter , also supplier are limited. If the smartphone company  changes their supplier of components or CPU, the performance of smartphone will change a lot. So the company have to stay under their suppliers’ rule and they have to accept their price, that will be reflected in the price of the final product inevitably. The smartphone company are not willing and will be not willing to take the risk to change their suppliers, in order to maintain the quality of their products. 5. Bargaining power of buyers: customers are not concentrating on price; when they decide to buy a new smartphone they will take into consideration the design and the prestige the product will give them. Sometimes they choose basing on the advertising they receive. So they do not have a strong influence on this industry. Firms get the power to influence their customer and their ability is to make them trust in their own brand, providing for some value added. Take iPhone for example, the function of iPhone is just as good as some that other smartphone could have; However, the price of iPhone is one of the highest in the entire variety of smartphone present in the market, just because the prestige of iPhone is very high. This example shows that the bargaining power of customer is quite low. PC INDUSTRY The computer hardware industry consists of companies that manufacture and assemble personal computers, computer hardware, and computer peripherals. This industry is highly competitive, which means that companies must continuously be innovative in order to sustain a competitive advantage. The major companies of this industry include Oracle, IBM, HP, Dell, Apple, and Toshiba. This analysis will focus on computer manufacturing since it is the largest component of the industry, containing 43.7% of the market’s total value. The computer industry has been rapidly growing and shows no signs of slowing despite the recent economic downturn. 1. Threat of New Entrants :PC market is dominated by some major competitors as Hp, Dell, Acer, Apple, and others who currently have nearly the entire market share; this will likely discourage any potential new companies from entering the market. So we can state that the personal computer industry is characterized by a very weak threat of new entrants. A huge problem that  has to be faced in order to entry this market is that the market requires significant investments to be made in research and development to continually develop innovative products as well as large fixed start-up costs for manufacturing and employees and customer service.Existing firms can benefit from their capabilities of manufacturing at lower prices because of the advantage of economies of scale, where the will have fewer per unit costs as a result of their large scale production. Companies trying to enter the market will initially have smaller production and will consequently have higher prices. In the personal computer industry there is currently much emphasis put on price because consumers have become more price sensitive as personal computers have become more or less a commodity. New entrants will not only have higher prices but they will likely have a less innovative product as well because they do not have equal funding for research and development as other established brands and they will also have to deal with the brand loyal customers that have trusted the existing players in the industry for years. By attempting to join the market without any market share it will also be important for a new entrant to focus its investments more heavily on advertising and marketing then existing brands. A new entrant to the personal computer market will likely not fare well and is almost guaranteed to always be a second mover as the larger companies will develop more innovative products more rapidly because of their many competitive advantages. 2. Bargaining Power of Suppliers: It is possible to identify three different groups of suppliers in the personal computer industry including hardware suppliers, software suppliers and service suppliers. The first group is not able to exert a significant power. The core of their products are generally standardized and they compete by focusing on creating better, more advanced products at a better price and not through their attempts to differentiate them. As a result, firms within the industry are able to switch between this kind of suppliers relatively easily. It is really in the hands of the firm and which strategy they are committed to that will determine whether or not they will utilize a high or low end supplier. On the other hand, suppliers of hardware and software within the industry play a critical role in the pricing of products. With the quality of a computer being largely  determined by their microprocessors and application system installed within them. If a firm is following a high quality strategy then it can be expected that their prices will generally be higher to reflect the higher prices they are paying their suppliers.In terms of service suppliers, the service that can be offered within the personal PC industry include internet, tech support and repair services. These suppliers focus highly on operational performance and relational performance in order to increase customer satisfaction. They also offer a variety of customer loyalty programs in attempts to lock in and expand their customer base while trying to gain the competitive edge over competitors within the service industry of personal computers. While the PC industry changes regularly, it can be observed that only the central processing unit (CPU) is a key input. All other items are commodity in nature and so don’t command a bargaining power. Intel has a significant market power as it is a single major supplier of microprocessor and has an 80% of market share.Thus, Dell as computer manufacturer holds a power over the suppliers as opposed to the suppliers holding a power over the manufacturers. It is the suppliers that are in direct competition with each other. The suppliers are often forced to slash prices or merge with larger companies in order to survive. Hence, the bargaining power of suppliers is moderate. 3. Bargaining Power of Buyers: The personal computer industry is somewhat vulnerable against the bargaining power of buyers. Personal computer buyers are price-sensitive. Buyers are interested in quality and specifications thus making consumer loyalty low. Should one company not offer a product a product to suit the customer’s needs, they will find one that will. Buyer power is reduced slightly as computers are increasingly seen as a necessity due to the importance of online communication and information processing. Moreover, in the last recent years, some new technologies came on the market providing customers with the possibility to have more and more alternative options to the personal computer as smartphones, tablet computers, and other handheld devices like Ipods have most of the same capabilities as a personal computer. Because of the availability, sleekness, and trendiness of these alternatives, personal computers are becoming more and more obsolete. Personal computer must differentiate itself  in order to regain market share and compete with these newer alternative options. Large businesses, governments and schools which buy computers in large volumes have the power to bargain on price, quality and service. PC manufacturers can reduce a threat of buyer power by differentiating their product.DELL has introduced a new way of selling (direct model concept); buyers can directly buy computers with DELL without a so called middle man. By using this concept, computers cost per unit can be reduced. Furthermore, buyers are able to customize the PC based on their needs. The basis of this model, the direct model concept is to improve efficiency by effectively eliminating the intermediaries thereby allowing the company to speak directly to the customer. Dealing directly with customers allows Dell to customize their orders according to the customers’ needs. But, despite several ways in which manufacturers have differentiated their products and found ways to increase switching costs, customers still see units as very similar and thus choose primarily on price.To conclude we can consider a strong bargaining power of buyers. 4. Rivalry among Existing Firms: There is fierce competition between the top manufacturers in the personal computer industry. As the PC has increasingly become a commodity in a household, the fight to keep costs low while bringing the best product to the market has become a never ending battle. Thus competitors are trying to produce a low cost, powerful machine with the most efficient operating system. Firms specialize in different areas in order to compete amongst their rivals. Some focus on innovation and attempt to bring the newest technology to their customers first. Nevertheless, others may focus on their distribution channel and services throughout their firm. For example, DELL is focusing on distribution channel and high quality service while others such IBM and Apple focus more on innovation. All these create differentiation to some extent. Low-cost production at DELL contributes its positive growth rate, while other major manufacturers are experiencing negative growth rates. However, one of the fiercest areas is the price competition throughout the industry. It is to underline that the determinants of a pc’s quality are the microprocessor and application systems installed. As a result, there is a direct correlation between the firm’s profitability and the profitability of the firm’s suppliers.The major  manufacturers as DELL, IBM, HP, Acer and Apple are in competition to produce the least expensive and most efficient machine. Japanese companies such as Fujitsu, Toshiba, Sony and NEC also have large market shares.This intense competition are beginning to be felt its effect.Some companies exit via selling to other companies or simply exiting the industry altogether. For example, Compact Computers was acquired by Hewlett-Packet in 2002 while Xerox exi ted the computer business and concentrate on printers. Today, regardless of the number of companies present, the computer industry will continue to expand and remain competitive for a number of years to come, although threat to industry rivalry will continue to be strong. 5. Threat of Substitutes and Complements: Although it is very hard and challenging for a new entrant to join the personal computer industry there are currently other growing industries such as the smartphone, tablet, TV set/top boxes industries which are predicted to affect the sales of personal computers. All those alternatives started to encroach on functionality that was once the sole purview of the PC. Also if those products have different major players, their offers similar benefits to consumers that a personal computer also has. Moreover the technology advances are improving those products day by day. Thus they continue to increase in popularity and in performance, leading the sales of personal computers to a decline. The internet can now be accessed through phones and tablets and they are more portable than a laptop. Currently laptops and personal computers offer many unique applications and are compatible with much more software than smartphones and tablets. If smartphones and tablets can attain greater memory space, processing speeds, and compatibility with similar software, smartphones and tablets may be an all-in-one alternative to personal computers. Not only smartphone and tablet, but also some advanced game device like Sony PS3 allowed consumers to watch DVDs, surf the web, and play the game directly online in addition to play traditional video games. As technology continues to increase these separate industries may merge into one, or at least drastically affect each other.Hence we can conclude that threat from substitutes is strong in the PC industry. Digital Music Portable Industry 1. Threat of new entrant: In this industry, threat of entry is medium because the production cost is quite low. For example, the cost of material, packaging, assembly of iRiver (H320) only costs  £69 and the company can sell it in retail shop at  £153 (Skee G., 2005) Therefore, it may attract new competitors to enter into the market due to the low cost of material and the high product margin. Furthermore, the International Federation of the Phonographic Industry (IFPI) reports that the demand for music on the internet and mobile phones is booming and it may replace physical formats such as tape, CD, and DVD in the future; hence, it can be predicted that the market is still growing gradually (The Computer & Internet Lawyer, 2005). As a result, many companies come into the market and pose new threat to existing companies. For example, Microsoft has recently entered to this industry and launched â€Å"Zune† into the market. Many experts believe that Zune might be a competitive rival with iPod; however, it is not easy for new entrants to gain market share in this industry. It is obvious that Apple is still the market leader because Apple has economies of scale in its production that Apple produces and sells iPod more than 10 million with the high margin cost in each year. Next, Apple’s product is highly differentiated from other brands that customers still buy iPod due to its differentiation. For instance, iPod Nano, the latest model from Apple, has attractive features such as full color screen and the copyright-click wheel button, and iTune system which customers can use it easily to buy and download songs into iPod from internet. As a result, it is difficult for new entrants which have recently entered into the market to develop product to overcome existing companies in the industry. 2. Threat of substitutes : he threat of substitute product in the industry is medium because digital portable music products are quite unique which could not be easily replaced by other products. Products have many advantages for customers. For example, it is cheaper to download songs from internet into iPod than buy CD audio. Next, the quality of sound is equal to an original CD after encoding into audio file format. Customers can enjoy listening music as the same as they enjoy listening music from original CD but cheaper price. Therefore, these are reasons why a MP3 player is still popular today. However, in this last recent years we can see the birth of new product which perhaps can replace MP3 player. They are the new mobile phone and smartphone that are provided with an integrated music players ( previously Nokia N91 with a built-in 4GB hard drive or Motorola E398 with removable memory card and now iPhone, Galaxy and so on). Music phone can download songs via WAP or GPRS and store it in a built-in or removable memory. Importantly, many experts believe that the music phone will be the most serious threat to the industry in the near future because it is all-in-one functions that customers can use it for both communication and entertainment. According to some recent research, the benefit of music phone will make some consumers may hesitate to spend  £149 on MP3 Player when they could buy music phone with  £169 or  £189. 3. Rivalry among existing competitors: In this industry, the intensity of competition is high because there are many players in the industry and each company try to complete with each other by developing new products in the market all the time. For example, Microsoft has recently launched their new product which is MP3 player â€Å"Zune†. It has many features which is different from other products in the market such as an integrated FM tuner, bigger screen, and WiFi connection. Microsoft reports that Zune can penetrate into the market and gain the market share from dominant companies. Two weeks after launching, it took the second place of the market from SanDisk and grabbed 9% of the U.S.A. market but following Apple whose its product (iPod) still dominated the market (Martell, D., 2006) Moreover, â€Å"Cut Price† is popular business strategies in the industry. Most companies use it to overcome with other competitors and it can drive the industry to be more competitive. For example, Creative is a MP3 Player manufacturer that lost the market position to Apple two years ago. In 2005, Sim Wong Hoo, the founder of Creative, declared war on Apple’s iPod by launching new and modern product (Creative Zen Neeon) which Apple tried to counter by cutting price on its product that it forced Creative to do the same thing in its product; therefore, the intensity of rivalry was increasing gradually from this situation. (Sudhaman A., 2005) Besides, the market is growing very fast in the industry that it could also make the industry to be more competitive as well. For instance, iRiver anticipates that MP3 player market in Thailand  will continue to grow increasingly and consumer’s demand will double in the near future; therefore, iRiver has launched new product in the market which it hopes to gain more market share from 13.7% up to 20%. (Veerasak, 2005) When the market is growing very fast; it tends to stimulate many companies to enter and launch their product in the market to gain profit in the industry. 4. Bargaining power of suppliers: In this industry, the bargaining power of supplier is medium because, firstly, there are a lot of suppliers which provide materials for companies such as flash memory, hard disk, semiconductor, and so forth. These suppliers mostly come from Asia region especially in China which is a major source for many companies due to the low price of material. Secondly, according to a supplier in the industry, iSuppli anticipates that the shipment of MP3 players with Hard Disk Drive (HDD) – based product is growing up to 42.6% in 2009 from 26.6% in 2004. Consequently, it made many suppliers come to produce material for MP3 Player market. (Electronic News, 2005) Thirdly, most companies in the industry have power to negotiate with suppliers regarding the price of material. Nowadays, the demand of digital music player is growing dramatically; therefore, the growth of the market made many companies have to produce their product in high volume in order to serve market’s need and it made suppliers lost bargaining power because the large production gives company to be able to order material in high volume from suppliers. Furthermore, some companies that need lots of material in their production tend to have a long-term agreement with supplier to supply them material. For example, Apple need to have lots of material such as flash memory and hard disk memory for its product; therefore, Apple decided to make a long-term supply agreement with flash memory manufacturers such as Samsung, Toshiba in order to get good deal of price and ensure to have material for their product up until 2010. 5. Bargaining power of buyers. The bargaining power of buyer in the industry is low. Although, there are a lot of competitors in the market, products in some companies made a great success in sales volume because of their specific characteristics, such as iPod for example. It is not product’s price but it is product’s differentiation and the brand of the product.  Firms have the power to address customers to choose their specific product focusing on marketing tools. As a result, Apple can set price for its product and it can push high switching cost to customers if they want to change to other products in the market. Importantly, customers buy iPod because it also contains good features and attractive appearance. For instance, although, the price of iPod Nano is higher than other competitors in the market, the excellent features and functions of the product such as it can be played movies and it has higher storage capacity compared to previous model (iPod Mini) made Apple to get lots of profit from iPod Nano in 2005 which iPod Nano is not only just Apple’s best-selling iPod, but also the best – selling digital music player model worldwide.

Design and Experimental Research of Electronically Controlled Common Rail System for Diesel Engines †Engineering Research Paper

Design and Experimental Research of Electronically Controlled Common Rail System for Diesel Engines – Engineering Research Paper Free Online Research Papers Design and Experimental Research of Electronically Controlled Common Rail System for Diesel Engines Engineering Research Paper ABSTRACT The electronically controlled common rail system presents many advantages, because the injection timing and common rail pressure can be controlled independently. An electronic control unit(ECU) to realize control functions is developed, and serious experiments about the injection system are conducted. The purpose of this project is to study the factors that affect injection characteristics. The results indicate that the injector has faster response when the common rail pressure rises, increasing the injection rate. One the other hand, the extension of control pulse width adds the valve open time, which increases the injection duration. The flexible injection characteristics can be acquired by controlling common rail pressure and pulse width coordinately. 1.INTRODUCTION With the increasing concern of the environment and more stringent government regulation on exhaust emissions, the reduction of engine emissions is a major research objective in engine development. In order to improve the engine’s emission performance, various technologies are adopted such as electronically controlled common rail system, clean alternative fuel, high efficient combustion organization, advanced turbo charging, exhaust gas recirculation(EGR) and advanced after treatment technology. The harmful emissions are generated in combustion process, so realizing ideal injection characteristics is one of the key aspects to improve combustion and reduce emissions. Electronically controlled common rail fuel injection system has been accepted as one leading technology in diesel engines, and this system has the following advantages: (1)The injection pressure and injection quantity can be adjusted and acquired flexibly. With high injection pressure independent of engine load and speed, the NOx and PM emissions can be minimized to meet the requirement of emissions regulation and optimize the engine performance. (2)The common rail installed between oil pump and injectors functions as a reservoir, and the fluctuation of oil from oil pump is stabled in the common rail, so the disturbance between injectors is decreased greatly. (3)Exact injection timing and injection duration can be realized with electronic control unit (ECU) over the entire engine load and speed range. (4)It is easy to package this system to a traditional diesel engine without much change. This paper discusses the configuration of an electronically controlled common rail system based on Caterpilar HEUI (Hydraulic Electronic Unit Injection) injector, and introduces the development of ECU hardware and software. Long tube method is used to investigate the characteristics of the fuel injection system, and the result shows how the common rail pressure and control pulse affect the injection characteristics, which provides the foundation of soft engine control. 2. SYSTEM OPERATION Figure 1 is a schematic of the electronically controlled common rail system based on HEUI injector. This system is comprised of oil and fuel adjusting structure, HEUI injector, electronic control unit(ECU) and various sensor. Note this system incorporates two fluid circuits, fuel and oil. The fuel circuit provides fuel to the injector. The fuel transfer pump draws fuel from the fuel tank and delivers it through a filter to the injector. System pressure is 0.2MPa typically. The oil circuit generates high pressure oil needed for HEUI injector. Oil is drawn from the engine oil sump and supplied trough the filter to the high pressure pump. The high pressure oil pump is an axial piston pump, and it raises the system’s oil pressure to the actuation pressure level typically between 4 and 23MPa. This high pressure oil flows through lines into the oil common rail located near the injector. The rail stores the oil at actuation pressure adjusted by the rail pressure control valve (RPCV). The ECU reads engine sensors to identify the engine’s current operating condition and produces the waveform required to drive the HEUI injector solenoid. When the ECU gives a control pulse, the solenoid is energized moving the poppet valve from the lower to the upper seat. This action admits high pressure oil to the spring cavity and the passage to the intensifier piston. As the piston and plunger move downward, the pressure of the fuel below the plunger rises, and the nozzle needle lifts allowing injection to occur. Injection continues until the solenoid is de-energized and the poppet moves from the upper to lower seat, blocking oil flow. The plunger return spring returns the piston and plunger to their initial position. As the plunger returns, it draws replenishing fuel into the plunger chamber across a ball check valve. Since the ratio of areas between the intensifier piston and plunger is 7, the actual injection pressure can reach 30~150MPa. Pre-Injection Metering (PRIME) is HEUI’s rate shaping device. When the plunger moves downward, pre-injection occurs before main injection through a precious spill hole. Figure 2 shows a representational cross section of the HEUI injector. 3. ECU STRUCTURE In electronically controlled common rail system, the major operation parameters are injection quantity and injection timing controlled by High-speed Solenoid Valve (HSV) in the injector. The basic injection quantity is determined by common rail pressure, engine speed and pedal position signal, and other supplementary signals such as atmosphere pressure and oil temperature make modification to the basic injection quantity. A closed loop control strategy is used to stabilize the speed. Figure 3 is the block diagram of speed control principle. The ECU consists of microcontroller, input circuit, HSV drive circuit and display module. The central part of ECU is the microcontroller (MCU). Motorola’s serious MCU has become an industrial standard in engine control. Both GM Inc. and Caterpillar Inc. adopted Motorola’s MCU in their electronically controlled engine products and made remarkable result. In this paper, the high-performance 8-bit MC68HC908 GP32 MCU is employed to accomplish control functions, and this chip owns the following advantages: (1)32 Kbytes of FLASH memory with in-chip programming capabilities and in-chip programming firmware for use with host personal computer which does not require high voltage to entry (2)8 MHz internal bus frequency and clock generator module with 32-KHz crystal compatible Phase Lock Loop (PLL) (3)Two 16-bit, 2-channel timer interface modules with selectable input capture, output compare, and Pulse Width Modulation (PWM) capability on each channel (4)8-channel, 8-bit successive approximation analog-to-digital converter (ADC) to satisfy multi-input requirement (5)System protection features such as optional computer operating properly (COP) rest, low-voltage detection with optional rest and illegal address detection with rest 3.2 Input circuit of ECU The top dead center (TDC) signal of cylinder must be detected first for precious timing control. A signal plate is installed on the rim of flywheel. When the engine piston arrives at the top dead center position, the signal plate moves faced to a magnetoelectric sensor, and then the TDC signal comes into being. A reshaping circuit is used to regular this signal to supply MCU for input capture. A rotary timing wheel is attached to the engine crank shift, and produces 720 standard square waves every cycle. The engine speed can be calculated in MCU using these signals, and coordinating with TDC signal, the exact moment of HSV operation is determined with a tolerance of less than 0.5 crankshaft angle. The analog signals such as oil pressure, oil temperature and pedal signal are induced to ECU’s AD channel through an amplify circuit and a modulate circuit. 3.3 HSV drive circuit The HSV in injector undertakes the task of injection control. Fast-open is needed to ensure exact injection timing and forming high pressure quickly, and fast-close is required to satisfy shutting off quickly and unloading stably. The dynamic response characteristics of the injector affect the main performance of injection system directly. In order to create strong force to overcome the resistance of return spring, a 60V high-voltage is adopted for the solenoid, and the Pulse Width Modulation (PWM) control method is used to keep the holding current. Figure 4 shows the principle of drive circuit. When the MCU gives an injection control pulse, the injector gets 60V high voltage, and the current in solenoid rises quickly according to the system resistance and inductance. 1ms later, the circuit turns to PWM mode, and the average current of PWM pulse keeps the valve open with low power dissipation. The maximum open current is 4 ampere and the average holding current is 1.5 ampere. This operation mode ensures the injector to run reliably in a long term. 3.4 Display circuit In order to acquire engine real-time status, DM-162, a character liquid crystal diode (LCD) display chip, is used to monitor the engine speed, injection timing and injection pulse width. The small-size DM-162 expends low power, and stores 160 different array character graphs in its internal character generator. It has convenient interface to MCU, and it is easy to accomplish the display function by giving the corresponding character storing address in software. 3.5 ECU software structure The control software is edited by Motorola assembly language, and it includes the following modules. (1)Injection control module: On the condition of the common rail acquiring stable pressure from pump, the MCU calculates the injection quantity on the basis of engine speed and pedal position signal. After modification, the MCU produce a corresponding pulse to the HSV drive circuit. A closed loop control algorithmic is used to adjust the injection quantity to stabilize engine speed. The injection timing in different engine operation mode is acquired by software table-look-up method. (2)Data acquisition and process module: This module scans the signals from various sensors, and use software filtering to eliminate false signals due to engine disturbance. (3)Display module: According to the display demand, the engine speed, the crankshaft angle of starting injection and injection pulse width are showed in different position of the LCD screen. In every software cycle, the data refresh to keep the real-time engine status. (4)Malfunction process module: This module judges whether the signals from sensors exceed its limited value. When a serious error occurs, the MCU turns off for safety. 4. EXPERIMENTAL RESULTS AND DISCUSSION After finishing the development of electronically controlled common rail fuel system, long tube method is used to measure the injection characteristics of HEUI injector. A long tube mechanism is attached to injector fuel outlet for realizing this method, and a high-precision pressure sensor is used to gather the fuel pressure information in the long tube. The injection rate and injection quantity per-cycle can be calculated according to pressure wave transmission theory. In practical treatment, formula (1) to (4) are applied for calculation. (1? (2) The injection quantity on a time basis for one cycle under different common rail pressure and control pulse width are shown in figure 5. The relationship between them can be seen from this figure. (1)Under a fixed common rail oil pressure, the injection quantity increases proportionally with pulse width in a certain rang. Under a fixed pulse width, when the common rail oil pressure rises, the injection quantity increases correspondingly. (2)The control pulse width and common rail oil pressure determine the opening properties of HSV. When the pulse coming from MCU is less than 0.8ms, the HSV can not get enough response time for action. If the oil pressure in the common rail is fairly low, the intensifier piston accelerates slowly, therefore the fuel can not acquire enough pressure to open the nozzle in very short time. For example, when the common rail oil pressure is 5MPa, the injection does not occur until 1.5ms-width pulse exerts on the solenoid. (3)The volume of plunger chamber determines that the maximum injection quantity in one cycle is 88mg/cycle (66ml/min). With the increase of common rail oil pressure, the pulse width to achieve the maximum injection quantity decreases correspondingly. 4.2 Effect of pressure and pulse width on pre-injection Pre-injection can adjust the initial portion of fuel delivery to control the amount of fuel delivered during ignition delay and main injection. It makes the fuel in main injection to burn quickly and stably. This process modifies the heat release characteristics and is beneficial in achieving low emission and noise levels. Figure 6 shows the effect of pressure and pulse width on pre-injection ratio. (1)Under a fixed pulse width, the pre-injection ratio presents decline tendency with the decrease of the common rail pressure. However, the over-low common rail pressure makes pre-injection ratio rising. This result appears because the flow duration of the spill hole in the PRIME is quite short under a higher common rail pressure, and this makes the pre-injection quantity keep unchanged, so the pre-injection ratio decreases with the total injection quantity increasing. When the common rail pressure changes at a lower level, the spilling time increases apparently, therefore the proportion of pre-injection quantity adds correspondingly. (2)Under a fixed common rail pressure, the extension of control pulse width causes the increase of total injection quantity before it reaches the maximum value, accordingly the pre-injection ratio decreases. 4.3 Effect of pressure on injection rate Figure 8 presents the injection rate shape in various control pulse width when the common rail pressure maintains 10MPa. The injection duration and injection quantity increase significantly with the extension of pulse width, but the injection rate keeps invariant mainly on the whole. To conclude from figure 7 and figure 8, the main factor of affecting injection rate is common rail pressure, and the pulse width is the main factor of affecting injection duration. On the basis of the result, the injection characteristic can be controlled flexibly to satisfy the practical engine operation. 5. CONCLUSION The electronically controlled common rail fuel system opens many opportunities for improving engine performance, and the injection control is the most important part of this system. Through the development of control system and experimental research, the following conclusion can be obtained: (1)The exact injection control is achieved by applying MC68HC908 GP32 microcontroller to the ECU. Long tube method is a convenient and precious means to measure the injection process of fuel system, and the injection characteristics acquired from this method provides the foundation of soft engine operation. (2)The structure of the injector determines the maximum injection quantity in one cycle and the minimum pulse width to open the valve. (3)The desired injection characteristics can be realized by controlling the common rail pressure and pulse width coordinately. The common rail pressure makes major effect on the injection rate, while pulse width makes major effect on the injection duration. (4) The injection rate and injection duration of electronically controlled common rail system are independent on the engine load and speed.

Evaluation Effectiveness Of The Safety Net Program Social Work Essays

Evaluation Effectiveness Of The Safety Net Program Social Work Essays Evaluation Effectiveness Of The Safety Net Program Social Work Essay Evaluation Effectiveness Of The Safety Net Program Social Work Essay The Safety Net plan administered by the Child and Family Guidance Center is a school based intercession plan. Safety Net Intervention Servicess for High Risk Youth, was administered to 160 pupils, at Richardson West Junior High School, during the 2009 2010 school old ages. The pupils are referred for plan engagement by parents, instructors or other school forces for bar or early intercession of behavioural concerns that hinder school success. However, plan engagement is voluntary and even with parental permission ; pupil must exhibit willingness for plan engagement. Safety Net is a ten- hebdomad equal facilitated course of study based intercession theoretical account, administered during the school twenty-four hours. The Safety Net plan provides a full scope of bar and early intercession services including preventative instruction, reding and accomplishments preparation. The Ohio Young person Problem, Functioning, and Satisfaction Scales, is the assessment instrument administered to plan participants for outcome step. The 48-question short reply signifier measures pupils perceived jobs, compared with pupils perceived operation, within the past 30 yearss. The assessment instrument, administered in the signifier of a pre and post-test study, administered prior to intercession and once more at the apogee of the ten-week Safety Net plan engagement. By comparing, the average norm of the 160 pupil participants pre and post- trial tonss, measuring for capable group norm of each, measuring for statistical difference, after plan completion to find the effectivity of the Safety Net plan for this capable group. Evaluation of the effectivity of the Safety Net plan An scrutiny of current literature on school based intercession is expected to turn out that school based intercession is an effectual method for handling kids. Coupled with an analysis of descriptive statistical informations from the Safety Net plan, for the intent of plan rating the Safety Net plan will turn out to be an effectual intercession method, for the 160 kids -student engagement group. The determination to research the subject of the effectivity of school based intercession plans came as the consequence of a practicum experience as a Safety Net counsellor, while functioning as a alumnus pupil houseman for the Child and Family Guidance Center, in Dallas, TX, spring 2010. As a societal work professional and former particular instruction instructor, the wellbeing of kids and the plans and intercession methods used to handle them is personally relevant. Child welfare societal policy remains an evolving precursor, in America, which sustains the seasonableness of this organic structure of research. Many school-based intercession plans receive federal support therefore ; all taxpaying citizens are stakeholders in the wellbeing of today s kids who are the kernel of social hereafter and hence, this research is comparative and informational to a wide audience. The Family and Child Guidance Centers Inc, assumed name Child and Family Guidance Centers is a non-profit corporation functioning households impacted by mental unwellness, kid maltreatment and disregard, bad behaviours, and substance maltreatment. The bureaus mission is, To supply quality accessible mental wellness services to beef up kids, households, and communities. Established in 1896, Child and Family Guidance Center has nurtured kids, strengthened households, and sceptered persons by supplying comprehensive solutions to life s jobs through guidance, instruction, public consciousness, and community partnerships for over 113 old ages. The Safety Net Plan is one of many plans included under the parent organic structure of services that Child and Family Guidance Center provides. Others include Psychiatric A ; Therapy Based Servicess for Adults, Children, and Families Program. This equips households with skills/resources to cut down chronic jobs including mental unwellness, house hold force, kid maltreatment, and homelessness through an array of household focused, mental wellness services.

Co-occurring Mental Health A ; Substance Abuse Services Program provides prevention/intervention services to youth with behavioural issues that put them at hazard for substance abuse/addiction. Equally good as supplying intervention to persons diagnosed with co-occurring mental unwellness and substance maltreatment to cut down the negative effects of the double diseases. Parent A ; Family Educa tion The Family and Community Education Program ( FACE ) serve households affected by kid maltreatment, divorce, or disfunction. It seeks to stabilise households by learning accomplishments to turn to jobs that stress household systems and put household members at hazard. ( Child and Family Guidance Center is the exclusive supplier of rearing instruction services to Child Protective Services for 19 county parts within the province of Texas. Finally, the Safety Net Intervention Servicess for High Risk Youth, the school based intercession plan that serves as the beginning of this plan rating. Child and Family Guidance Center is a nationally acclaimed plan, renowned for its regard and indorsement by the Federal authorities, as proven by the continued successful acquisition of federal support and noteworthy usage of resources sanctioned with Federal indorsement. Child and Family Guidance Center has been a recognized spouse of the United- Way since 1924 ( Childandfamilies.info ) . Childs are a particular population, who possess a particular leaning for alteration hence, it is easier to add strength than it is to deduct from failing ( Openshaw, 2008, p. 91 ) . By placing these pupils and turn toing, bad behaviours, in in-between school, places these pupils at an advantage, as they are able to have the necessary support to go resilient and the tools necessary for school success. Having observed that every individual has the ability to get the better of hardship if of import protective factors are present in that individual s life , it is inherit that at hazard pupils are identified and receive intervention in school based intercession plans such as Safety Net ( Krovetz, 1999 ) . Resilient kids have been found to possess four common properties: Social competency ( the ability to arouse positive responses from others, therefore set uping positive relationships with both grownups and equals ) . Problem- work outing accomplishments ( planning and resourcefulness in seeking aid from others ) Autonomy ( a sense of one s ain individuality and an ability to move independently and exercise some control over one s environment ) . A sense of intent and hereafter ( ends, educational aspirations, continuity, hopefulness, and a sense of a bright hereafter ) ( Benard, 1993, p. 44 ) . Students who participate in the Safety Net plan, must be willing participants, they must expose the ability to acquire along with the Safety Net counsellor every bit good as show the adulthood to map within a peer-facilitated group. A pupil who meets the lower limit demands for engagement in the Safety Net plan, already possess the inherit strength of resilience. Never underestimate the power of resilience ( Nims A ; Hamm, 2006 ) . Although pupils must come to the Safety Net plan volitionally, they must hold parental/ guardian permission, which includes a parental pre and station -test. This serves a signifier of parental support, in that parents must detect and be able to describe out on their pupils behaviour ( Cooper, 2000 ) . As good, Safety Net counsellors are required to document a lower limit of 10 contacts, with each participant, instructors, guardian or other mental wellness professional. This pattern cultivates an automatic support system for each single pupil participant. With cognition of plan engagement, pupils become unwittingly accountable to multiple grownups, who are likely concerned with their overall wellbeing. This pattern every bit good cultivates caring adult relationships that pupils may trust on, at the decision of the Safety Net plan. One of the first assignments given at the induction of the ten-week plan term is the choice of a Safe Adult by each pupil and both parties must subscri be a contractual understanding of answerability and support. The pupil is told to choose an grownup that they may reach in the event of crisis, need for support or advice. This is a support system of the pupils ain induction, this pattern cultivates job work outing accomplishments, liberty and a sense of intent ( Hallfors, 2006 ) . The above pattern of the Safety Net plan in cultivating, every pupil s leaning for resilience besides, establishes the protective factors that are through empirical observation necessary for get the better ofing hardship ( Openshaw, p.92, 2008 ) . These factors documented as being necessary for get the better ofing hardship within the household, school and community. To the acclamation of the Safety Net Program, before of all time diging into the through empirical observation based course of study, every bit good predisposes, an environment conducive for resilience and wellness by: Establish a lovingness environment at least one grownup who knows the kid good and cares deeply about the wellbeing of that kid. This plan affords each kid the liberty to place multiple lovingness grownups, at school, at place or in their community. This lovingness grownup is so in a place to expose in a non -threatening mode, positive outlooks, high clearly articulated outlooks for each kid and the purposeful support necessary to run into those outlooks. Many pupils, by and large, would non place an grownup and petition, clear outlooks for behaviour. This plan affords each pupil participation- meaningful engagement and duty ( Krovetz, 1999 ) . Professional values and beliefs sing service as a Safety Net Counselor include but are non limited to the followers: As a professional societal worker interning within a non- societal work specific place, one must trust on NASW s Code of Ethics as a usher to ethical determination devising ( NASW, 2002, Standard I ) , sing ethical quandary in keeping societal work values in a non-social work scene. This codification of behavior is particularly of import when working in an intern function, contracted with an bureau that places your service assignment inside another entity, such as a school. First, one must see the bureaus policies, which may or may non aline with societal work values and so the additive of adhering to the schools policies and processs, which may non aline with the overall values of the societal work profession. In cases such as this, it is imperative for societal workers to adhere, every bit closely as possible to the specified guidelines of both of their employing organic structures and when in uncertainty or struggle should mention to and adhere to NASW s Code of Ethics. Ethical qu andary are possible and likely in all degrees of pattern, but particularly during the Practicum experience, as the societal work professional is likely charting new professional land. Therefore, it is imperative for pupil housemans in all scenes to be familiar with bureau policy every bit good as their ain professional moralss, which will normally steer their values. Sing the facets of diverseness, school scenes, are normally comprised of diverse populations. These diverse populations range from socio- economic position, race, colour and national beginning to linguistic communication distinction and age. Sing age, when practising within a school puting one must be prepared and adequately equipped to address pupils, parents, school personnel/ other professionals and the community. A personal value in working with kids is the demand to get the hang and expose cultural competency and sensitiveness. This is an ethical authorization but as a former pedagogue and one with a deep affinity for the well- being of kids, it is imperative, to expose cultural competency and sensitiveness without unwittingly precipitating exclusion ( Fallick, 2008 ) . The Child and Family Guidance Center s acceptance and execution of the Safety Net Intervention Servicess for High Risk Youth, plan is likely motivated by the handiness of State and Federal support nevertheless the plan s design is in maintaining with the bureaus overall mission, To supply quality accessible mental wellness services to beef up kids, households, and communities. Therefore, based on the bureaus stated mission, the bureau is likely passionate about the results of this peculiar plan. Intrinsically, the plans design is in maintaining with their mark audience, extrinsically the bureau receives wages for plan execution in the signifier of grant support. This combination of incentives creates a diverse, yet balanced motive for plan execution ( Fallick 2008 ) . The end of this plan rating is to find the effectivity of the Safety Net plan. The coveted result is to turn out that school based intercession plans such as Safety Net is an effectual method for the intervention of behavioural and mental wellness concerns in kids. Make such plans, specifically the Safety Net Program, run into their stated aims of drop- out bar, character edifice, resilience and life-skill development for at-risk young person? It is one s outlook that the execution of intercession in the signifier of course of study based, peer- facilitated groups will hold a permanent consequence on participants overall school success. This plans disposal occurs within the general instruction scene, and while plan participants exhibit behavioural concerns that preclude their engagement in more mainstream activities, engagement in the Safety Net plan is a preventive and early intercession scheme. By using evidence-based pattern, in the signifier of student-centered course of study, c ultivating resilience and developing a support system of each single pupil s pick, the societal worker/ Safety Net Counselor is able to use their ego, their professional cognition every bit good as the pupil s equals in a positive manner to consequence alteration. The ends and mark results set Forth by Safety Net plan Changes that will advance the coveted result of pupils success in school, including: Dropout bar, precluded by inordinate absence and other signifiers of behavioural jobs, necessitated by lacking societal accomplishments and other internally regulated tools, such as self-efficacy and motive Character edifice, in the signifier of self-esteem, self-awareness, judgement and communicating Resiliency-the development of a support system of pupil s pick and designation of cognitive behavioural tools to get the better of jobs with household and equals Life accomplishments development, in the signifier, of end development, drug and intoxicant consciousness and bar Celebrated school Social Work expert ascertains that, one possible solution to the dropout job is for societal workers to work closely with in-between schools to assist place those pupils who appear to be at hazard when they enter high school. These pupils may be in particular instruction or in alternate plans, may hold failed categories, or received reding from the school counsellor to assist them get by with school- related jobs ( Openshaw, 2008, p. 122 ) . This is exactly the standard norm for designation as a campaigner for the Safety Net plan, as administered at Richardson West Junior High School. Parents, instructors, counsellors and other school forces, place Safety Net plan participants, by placing pupils with inordinate absence, which is frequently an index of a household in demand of support, or a pupil who may be deliberately losing school or one whom is deliberately absent from certain categories during the school twenty-four hours. Students who receive inordinate offic e referral or subject for behavioural misdemeanor, inordinate disciplinary action in the signifier of in- school and alternate arrangement based suspension. Equally good as the designation of pupils, who have had a demand to talk with school counsellors for aid in get bying with school-related jobs. Children are a really resilient client population, with bar and early intercession ; Safety Net counsellors are postured with the aid of single pupil s immediate stakeholders to place at-risk pupils and illicit positive alteration, by implementing the course of study by design. With the necessary constituents in topographic point as afforded by the Project Success course of study, successful completion of the ten- hebdomad course of study based group Sessionss, an outlook for pupil betterment towards the targeted behaviours is high. By placing at-risk pupils, the Safety Net counsellor is able to forestall jobs before they occur . The plans, course of study is structured so that the pup il with the aid, of the Safety Net counsellor receives the confidence of caring grownups, designation of issues before they escalate and the constitution of a peer support group ( Openshaw, 2008, p. 123 ) . Apparent end distinction between, the bureau, the school and the community does non be. Social scientific discipline research ascertains that schools are the primary suppliers of mental wellness services for kids. As opposed to primary attention doctors and other mental wellness professionals who chiefly serve as the mental wellness interventionalist for grownups. Research ascertains school based intercession feasibleness based on the fact that kids are required to go to school ( Hoagwood, Holly, Erwin, 1997 ) . In kids mental, emotional and behavioural wellness troubles are most frequently foremost noted within the school scene and therefore should logically be addressed within the school scene, as the first line of intercession and furthermore prevented if and when possible ( Bums et al. , 1995 ) . The value of supplying mental wellness services in schools was first recognized in this state in 1898 in Chicago, IL, in response to a pupil study on physical and mental wellness. Based on the study s findings, the Chicago school board authorized the first theoretical accou nt of school-based intercession programming for childhood mental wellness ( Gallic 1990 ) . The Safety Net plan, administered by the Child and Family Guidance Center is one such school based intercession plan. The Safety Net program- Intervention Services for High Risk Youth is a drop- out bar, character edifice, resilience and life -skill development plan for at-risk young person. It is an in-school partnership plan to assist at-risk young person addition positive decision-making accomplishments and diminish bad behaviours. The plan provides a full scope of prevention/early intercession services including preventative behavioural tools accomplishments instruction, guidance, and accomplishments preparation. The plan utilizes the Undertaking SUCCESS ( Schools Using Coordinated Community Efforts to Strengthen Students ) Curriculum, a research-based intercession theoretical account plan recommended by the Federal Government s Substance Abuse and Mental Health Services Administration ( SAMHSA ) ( CFGC, 2010 ) . The course of studies design seeks to cut down bad behaviours and better resilience factors in at-risk young person. An scrutiny of current literature on school based intercession is expected to turn out that school based intercession is an effectual method for handling kids. These research findings paired with an analysis of statistical informations obtained via the Ohio- trial, from recent Safety Net plan participants, for the intent of plan rating will probably turn out the Safety Net plan as an effectual theoretical account of school based intercession method. Research conducted on school based intercession, ascertains that the survey of inventions and alteration in school systems is non new. What is advanced is a strict outcome rating of a household of school based intercessions that targets the same job behaviour among a school age population. ( Hallfors, etl. , 2006 ) . An integrating of bing research coupled with the well-founded informations obtained as a contemplation of this plans unity in comparing with the national acclamation that the capable affair herein has received will turn out this integrative paper to be both timely and relevant to current societal policy sing the hereafter of young person. This mounting organic structure of research on school based intercession and bar continues to germinate and cultivate prevalence. Prevalence, in big due to its presentation in a big federal grant and National run from a pool of bureaus including ; ( Department of Education, Office of Juvenile Justice and Delinquency Prevention, and the Center for Mental Health Services ) as portion of a Safe Schools/ Healthy Students federal enterprise ( Hallfors, etl. , 2006 ) . Undertaking Success, ( Schools Using Coordinated Community Efforts to Strengthen Students ) was originally designed to forestall and cut down substance usage and maltreatment among high hazard, multi-problem striplings in alternate high school scenes. It was based on the Residential Student Assistance Program ( RSAP ) theoretical account used in residential stripling intervention installations, and adapted from the Westchester Student Assistance Program ( WSAP ) . The Student Assistance Program ( SAP ) theoretical account is similar to that of Employee Assistance Programs ( EAPs ) used to assist employees with substance usage or mental wellness concerns ( Shamblin, 2009 ) found six published studies that suggested that SAPs possibly effectual in cut downing substance usage and bettering academic public presentation for some striplings ; nevertheless, they reported that the surveies suffered from important methodological jobs. The Safety Net plan is chiefly based in the Systems theory of intervention, in that it assist pupils in the rating of their environment, in order to assist them thrive. It approaches all of the constituents that comprise a pupil s life, place, school, equals, community and ego. There are a few definitions of systems, that comprise the theory as a whole ; Multiple definitions: A group of interacting, interrelated, or interdependent parts organizing a complex whole A constellation of parts joined together by a web of relationships The parts form a whole, which is greater than the amount of its parts For the intent of the research survey, most pupils fall into the class of organic systems, defined as: Dynamical patterns parts accommodating to each other and to their environment as a whole Partss are massively entangled, interdependent Partss self-organize, learn, co-evolve organically Equilibrium in flux sensitive to initial conditions System non replicable, ca nt reiterate past Emergent alteration manage conditions of organic development and experimentation Unknown terra incognitas test and mistake ( Pawlick, 2004 ) . The plan marks in-between school kids ; larning to accommodate and boom in their environment is a life accomplishment that is movable throughout the class of life. Giving pupils the tools to understand that their actions affect those around them, and that the actions of others affect them, is a critical constituent of the accomplishment set development that Safety Net seeks to administrate. The Safety Net plan, harmonizing to The Project Success, Curriculum Implementation Manuel ( p.21 ) is based on a organic structure of research known as the Prevention Education Series, a Safety Net Counselor conducts this educational series, it is comprised of little, structured, leader-directed, equal facilitated, treatment groups. The Series combines both didactic and experimental attacks to accomplish its ends. The Safety Net program- Intervention Services for High Risk Youth is a drop- out bar, character edifice, resilience and life -skill development plan for at-risk young person. It is an in-school partnership plan to assist at-risk young person addition positive decision-making accomplishments and diminish bad behaviours. The plan provides a full scope of prevention/early intercession services including preventative behavioural tools accomplishments instruction, guidance, and accomplishments developing. By carry oning one-hour hebdomadal groups, for 10 hebdomads, the intercess ion is set into gesture. During the 10 hebdomads, the course of study outlines the undermentioned lessons, as a recommended format: a?â„ ¢Topic 1 Bing an Adolescent a?â„ ¢ Topic 2 Alcohol Tobacco, and other drugs a?â„ ¢ Topic 3 Family Pressures and Problems a?â„ ¢ Topic 4 Skills for Coping a?â„ ¢ Topic 5 Communication a?â„ ¢ Topic 6 Problem Recognition and Resolution a?â„ ¢ Topic 7 Stress direction and self-exploration a?â„ ¢Topic 8 Self esteem issues a?â„ ¢Topic 9 Anger direction a?â„ ¢Topic 10 Peer Pressure and Closing At the stopping point of the ten-week procedure, the pupils, receive the Ohio appraisal once more, as a posttest and an result step for finding if pupils developed an apprehension of the lesson, and the ability to implement the accomplishments. Harmonizing the Undertaking Success Manuel the expected results of the Safety Net plan are as follows: dropout bar, precluded by inordinate absence and other signifiers of behavioural jobs, necessitated by lacking societal accomplishments and other internally regulated tools, such as self-efficacy and motive. Through the lessons outlined in the course of study usher, the outlook is that pupils will have the necessary header and societal accomplishments for school success and high school bar. The following targeted result is character edifice, in the signifier of self-esteem, self-awareness, judgement and communicating. The coveted result that follows character development is resilience, the development of a support system of pupil s pick and designation of cognitive behavioural tools to get the better of jobs with household and equals. The concluding desired result of the Safety Net Program and Project Success course of study is life accomplishments development, in the signifier of end development, drug and intoxicant consciousness and bar. After plan referral, choice for the Safety Net plan, intercession method relies on the confidential showing signifier on which pupils personally identify behaviours, which place them in a bad class, of dropping out of school or other foreseeable behavioural, academic or legal jobs of a condemnable nature. This signifier assesses hazard, in order to place bad pupils. Once, pupils are deemed to be high hazard they are given a pre-test, they undergo 10 hebdomads of intercession, targeted behavioural alterations will be discussed in the organic structure of the paper. At the apogee of the ten- hebdomad intercession, pupils take a posttest ; these two trials receive scientific comparing as a agency of finding plan effectivity. As good, pupil s parent or guardian takes a parental version of the same assessment tool ; parental informations will be included in the rating every bit good. Students who participate in the Safety Net plan, must be willing participants, they must expose the ability to acquire along with the Safety Net counsellor every bit good as show the adulthood to map within a peer-facilitated group. A pupil who meets the lower limit demands for engagement in the Safety Net plan, already possess the inherit strength of resilience. Never underestimate the power of resilience ( Nims A ; Hamm, 2006 ) . The pupils, which the Safety Net plan accepts for engagement, must exhibit a desire for plan engagement. Safety Net counsellors are advised non force or promote engagement of any pupils, who does non exhibit a willingness to be a portion of the group therapy procedure. The appraisal setup herein described as the Ohio The Ohio Mental Health Consumer Outcomes System, Youth Problem, and Functioning and, Satisfaction Scale is an appraisal administered in the signifier a pre and posttest study incorporating 48 inquiries given to- both parents and pupil participants. The instrument consist of 20 inquiries in respect to day-to-day operation, 8 inquiries sing relationships, emphasis and mental wellness intervention and eventually 20 inquiries sing mundane activity in relation to family and equal relatedness. Ethical considerations for working with kids, include the undermentioned Basic policy that affects pupils, take parting in plans such as this, IDEA- Persons with Disabilities Act, NCLB- No Child Left Behind, and educational best patterns of each in relation to the NASW Code of Ethical motives The completion of this plan rating, defined as a set of doctrines and methods that aim to find what works in human service bringing systems ( Grinnell, 2007 ) . The completion of this plan rating utilized the execution of quantitative informations analysis utilizing descriptive statistics and a mated samples t-test as the methodological analysis. By implementing, the one group pretest-post trial as the research design, for the aggregation, each pupil s pre and station Ohio trial mark. The mated samples t-test was ran to find the groups Ohio assessment norm mark, in order to find if a statistically important difference was present after finishing the Safety Net plan. For the intent of finding if plan engagement, depicts an betterment in this sample groups behavioural operation, as stated in response to the Ohio trial questionnaire. The hypothesis, established for this research design, states that the Safety Net plan would turn out to be an effectual intervention method for the sampl e group, which if proven, could probably reiterate, in a broader survey of the plan s effectivity. The sample consisted of secondary informations, in the signifier of a pre and post-test collected on 120 pupil participants, during the 2009-2010 school old ages. The Ohio appraisal setup contained 48 inquiries given to pupil participants, as a agency of measuring pupils job badness in comparing to pupil s degree of working anterior to intercession and at the apogee of 10 hebdomads of intercession. The instrument consists of 20 inquiries sing day-to-day operation, 8 inquiries sing relationships, emphasis and mental wellness intervention and eventually 20 inquiries sing mundane activity in relation to school, place and equal relatedness. The statistics for the sample group are as follows: Pre- Trial Mean: 76 Standard Deviation 10 Post- Trial Mean:80 Standard Deviation: 8 T-stat: 3.9 The T- stat, finding of 3.9 is statistically important with a step degree.05, as the significance index. The information once and for all proves that the pupil s degrees of perceptual experience sing working when compared with pupil perceived jobs, significantly increased after completion of the Safety Net Intervention plan. The consequences suggest that the pupils perceived working in relation to their jobs improved from 76 to 78. One defect in the researches design is that it does non see the Ohio tonss of the parents and instructors who may hold a more nonsubjective sentiment than the pupil is leting for a broader reading of result ( Grinnell, A ; Unrau, 2007 ) . Harmonizing to Durant, procedure result based plan rating, are limit the plan rating by neglecting to react to subsequent unfavorable judgment, by turn toing pertinent constituents of holistic rating. ( Durant, 2001 ) . Conducting, an through empirical observation based research survey is a strong project, which requires cognition, accomplishment and ability. The research contained herein, is a direct contemplation of the research workers ability and skill degree. The research procedure contained herein depicts capable command ; with a greater apprehension of the research p
