Macro and micro economics analysis Research Paper

Macro and micro economics analysis - Research Paper Example Toyota Camry is one of the popular cars that are being manufactured by Toyota. The car is available in global market in two classes, such as Narrow-Body; Compact class and Wide-Body; Mid-Size class. The car under these segments has achieved huge fame since its establishment in the year 1982. Indian car industry is very much potential and year after year the demand of cars is increasing significantly. The target audience of Toyota Camry in Indian market is the people who are highly educated and enjoys high living standard. Both men and women over 30 years of age are the key target consumer of this particular product. Indian automotive and car market is highly potential and competitive enough. Maruti Suzuki, Hyundai Motors, Tata Motors, Ford Motors and Mahindra and Mahindra are the major competitors of Toyota in Indian market (Kotler, 2009). Maruti Suzuki is the leading player within the Indian Vehicle industry according to the market share figure 2010 (Figure 1). Microeconomics Market Mechanism: Demand and Supply Considering the market mechanism in India, historical facts help us to understand the Indian market. India started manufacturing automobile after 1947. Before Independence in the times of 1920, the Maharajas possessed cars especially of Rolls Royce as their status symbols. With time after independence, the need for a people’s car evolved and the middle class families also started to own cars. Initially the indigenous automobile companies captured the majority of market share but with the liberalization in government policies, the foreign automobile giants like Toyota started to invest in the Indian market. For launch of Toyota Camry, Toyota can look at the positive indicators of Indian market which indicates that the Indian car market is the fourth largest in the continent of Asia and stands out as the fifth largest manufacturer of commercial vehicles. The price elasticity of demand and supply in the Indian market are the key factors that Toyota would need to consider before the launch of Toyota Camry. It is to be kept in mind that the cars in India are considered as a luxury product. Also the Indian market consists of consumers ranging from lower class to lower middle class to middle class to upper class. Thus various sections of the society according to their levels of income make the Indian car market a mixed bag. Thus the price of cars in Indian car market is a significant factor as market responses largely vary with respect to changes in the car price. With unit changes in price of the cars, the demand of the cars in India would decrease and the supply of cars in India would fall. Thus the price elasticity of demand and supply for cars in India is greater than 1 showing the demand and supply id highly elastic with respect to price of cars in India. Also the rise in price of related goods of car like petrol, diesel also affects the demand and supply of cars in India. Thus the factor of cross-elasticity of indirect goods like petrol is also present in the Indian car market. The income elasticity on demand and supply in the Indian car market also needs to be considered for the launch of Toyota Camry. The factors of production for Toyota Camry with respect to its launch in the Indian market include an analysis of the demand and supply of the car market in India. The Indian car market was de-licensed in 1991 with the gates in automobile sector opened for 100% investment by the foreign

Stagnant Democracy Essay Example for Free

Stagnant Democracy Essay Democracy, whether in its early or current state, needs constant improvement even if it is a government system that is highly respectful of its constituents.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Henry David Thoreau lived at a time when democracy was finally being recognized as oppressive in itself because the governing system was becoming stagnant.   The laws that citizens had to abide to were being criticized because of the injustice its system was already imposing on other races like Mexicans and Negroes.   Thoreau and Ralph Waldo Emerson have simply seen that the legal system has become inefficient if not a means for oppression because of its taxes and treatment of others.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Society needs persons like Thoreau and Emerson because they are people who are able to see and declare the evils of society.   Only when declarations such as those made by them are given attention can any government or system improve.   It is upon reflection of their ideas when true great men can enact changes that would be able to improve an always imperfect society.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Both Thoreau and Emerson, even if they can be deemed as rebellious, do represent the traditional Western or American values because what they espoused in their writings were still democratic.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Thoreau, although he hints on individualism and disadvantages of the political system in his suggestions for civil disobedience, is merely applying his very rational beliefs and principles.   He is merely promoting a different concept that will be actually for the good of his community.   His suggestion for a non-violent revolution is democratic in itself because it is peaceful. Thoreau believes that every man has the power to enact change in his society even if he is not part of a majority. He says that a vote may be an act of one to show his agreement or dissent on certain issues but this is not enough to really change what is wrong in society.   He sees the exercise of voting as not enough.   To be true to one’s self would be to express fully what one is against to†¦ such as the way he has been stubborn (and consequently punished) in his non-payment of certain taxes.   He believes in the government because it can organize communities peacefully but insists that a political body can only be truly successful if it respects the individual.   In this way, he is actually espousing the very basic principle of democracy.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   He may seem rebellious when he attacks the government for imposing the taxes for Christianity but the basic formulations of his principles are very Christian. He believes that he is able to give back his spiritual obligations in other ways which are more useful to society.   His writings are testimony of his own contribution to the community he belongs to.   He insists that taxes are merely oppressive when people blindly pay it while they can share their skills and talents in other forms that will serve the community just as well.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Emerson is also representative of the liberal American or Western values because he is able to find the freedom of speech to attack the problems of the society.   The theme of self-reliance is not selfish but civic because it upholds the dignity of an individual which in turn can contribute better to society.   He believes that the society during his time is already in need of a wake up call because of its reliance on conformity and consistency. He saw that men were becoming cowards to express what is fair and just because of the need to adapt to the opinions of other who are simply obeying the laws blindly.   He sees that most people are already trapped into making very wrong decisions because of the fear that people will attack their views and actions because of what they had done in the past. According to Emerson, people who are not able to rely on their instincts with regard to what is right and wrong because they are always concerned on how society will react to them become prisoners of their cowardice.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Emerson may seem like a heretic when he attacks the hypocritical expression of faith many Church leaders were making but his views are basically Christ-centered.   His idea that the Church has become overbearing because of its strict adherence to religious laws is true.   Morality, for Emerson, is to look inside one’s self and find the truth and what is ultimately good for the individual and the others who surround him.   He believes that God provided each and every one of us with the instinct to know what is correct or wrong and that too much reliance on Church teachings can lead one to further mistakes simply for the sake of conformity.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Thomas and Emerson are highly for democracy and God but the way they have expressed themselves can seem rebellious to those who insist in following unjust laws.   As Martin Luther King Jr. has expressed in his own writings, laws that disregard the higher morals it supposedly adheres to are ineffective and disobedience to these is simply necessary. In fact, King is correct in establishing that disobedience is actually democratic and spiritual.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Democracy may have established laws that protect the security of many but it is still imperfect.   Individuals like Thoreau and Emerson are truly important to help this political system improve and correct itself.

Health Benefits of Alternative Therapies

Health Benefits of Alternative Therapies The popularity of alternative therapies in the past two decades has been accompanied by a proliferation of sociological works in investigation different aspects of this phenomenon. A major strand of the literature in the sociology of alternative medicine, which concerns three social actors: users of alternative therapies, practitioners of alternative therapies; and physicians (the orthodoxy). Research on users of alternative medicine has mainly investigated the causes of peoples use of these modalities and has focused on why people use alternative medicine? Research suggests the one reason people use alternative therapy, such as Occupational Therapy, is that they are dissatisfied with the health outcomes of orthodox medicine (Holden, 1978; West, 1988; Sharma, 1996; Spiegel et al., 1998). It is argued that conventional medicine has been unable to cure degenerative and chronic illness and has failed to alleviate pain associated with conditions such as arthritis, and back and neck injuries (Ingliss and West, 1983; Anyinam, 1990). Sharmas (1992) qualitative study of 30 users of various alternative therapies in Britain, including Occupational therapist. Provided support to the idea that patients seek alternative therapies in order to cure an illness that has not been successfully dealt with by GPs. Similarly, Furnham and Smith (1988) and Furnham and Forey (1994) in their British studies compared patients of GPs and patients of alternative practitioners and showed that the latter group was ore sceptical of the efficacy of orthodox medicine. T hey reached this conclusion based on the responses of subjects to statements such as Doctors relieve or cure only a few problems that their patients have, and Most people are helped a great deal when they go to a doctor. Other arguments have been made about the use of alternative therapies, looking at how patients arent necessarily dissatisfied with the health outcome of biomedicine, but rather they are dissatisfied with the medical encounter or the doctor patient relationship (Parker and Tupling, 1976; Taylor, 1984; Easthope, 1993). According to this argument in the literature, doctors spend too little time with, and have little respect for, their patients, who often are not informed of the nature of their illnesses, diagnoses and prognoses. It is argued that doctors have lost their human touch and todays medicine can best be characterised as Fordist medicine which produces alienated and dissatisfied patients. In support of this argument, Sharmas (1992) interviews with alternative therapists clients reveal that they believe GPs spend too little time with patients. Furnham and Forey (1994) also found that users of alternative medicine are more likely to believe that GPs do not listen to what their pa tients have to say. Health Promotion According to Nelson (1997) Occupational therapists understand the potentials of various occupational forms that are meaningful and purposeful to the individual. The therapist hopes and predicts that the occupational form will be perceptually, symbolically, and emotionally meaningful to the person; that the occupational form and the meanings the person actively assigns to it will result in multidimensional set of purposes, and that the person will engage in a voluntary occupational performance. In other words, when therapy is best, the person is full of purpose. Therefore Occupational therapists have a huge concern set around the promotion of health. Thorogood (2004) argues that sociology as a discipline is based on critical analysis and as such, can contribute to health promotion by focusing on questions that go beyond simple definition. In other words sociology can and should engage in debate around why health promotion has evolved the way it has rather then merely trying to establish a static definition of health promotion itself. In this way sociology can help health promotion to be reflective in terms of its role and development. While this means sociology is distinct from health promotion, it is none the less a crucial contributor to the development and practice of health promotion. Ryan et al (2006) approach to health promotion states that it has been hugely influenced by the fact that medicine has been the dominant model within health-service provision and a clear division exists between those who support the medical model of health and those who argue for a more holistic and/ or social model of health. Within health services, models of care are fairly well understood and well established as conceptual entities. Models of Health Care Looking at the bio-medical model, Atkinson (1988) discusses how within this model health is the absence of biological abnormality, it believes diseases have specific causes, that the human body is likened to a machine to be restored to health through personalised treatments that arrest, or reverse, the disease process, and that the health of a society is seen as largely dependent on the state of medical knowledge and the availability of medical resources. Bio-medicine and the health care practices arising from it occupy a paradoxical position in contemporary societies. On the one hand, there is continued enthusiasm for new medical breakthroughs as people seek treatment for an increasing range of conditions. On the other hand, there is also some disillusionment with clinical medicine and growing distrust of doctors etc. despite massively increased investments in medical research and health care, most of the diseases of modern society remain stubbornly resistant to effective treatment, let alone cure. Health professionals and doctors in particular, have been criticised for having a detached, impersonal approach. Some have linked this to the bio-medical model objectifying illness and reducing patients to little or more then a collection of symptoms. Critics such as Oliver (1996) have argued that more attention should be given to the social, psychological and political aspects of illness and disability. Professionals such as Occupational Therapist have responded to this by looking beyond the medical model and adopting a more person-centred approach to patient care. In this context, sociologists are interested in the ways that individual experiences of illness are shaped by wider social contexts, emphasising that the transition from health to illness involves significant changes in social status and therefore the attention of governments and an increasing number of health professionals has turned to the social and environmental influences on health giving rise to a new social- medical model approach to health based on disease prevention and health promotion. Taylor Field (2007) focuses on how health is more than the absence of disease; it is a resource for everyday living. It looks at how diseases are caused by a combination of factors, many of them being environmental. The focus of enquiry is on the relationship between the body and its environment and how significant improvements in health care are mostly likely to come from changes in peoples behaviour and in the conditions under which they live. Occupational therapists draw their attention on this model and it can be understood in there inter-related approaches. The first focuses on individual behaviour and lifestyle choices, the second looks at peoples immediate social environment, and their relationships with others and the third is concerned with general socio-economic and environmental influences. The emergence of a new philosophy sometimes referred to postmodern value system has also led to the rise in alternative therapies (Bakx, 1991; Easthope, 1993; Sharma, 1993). Today most people regard nature as caring, gentle, safe and benevolent; they hold anti-science and anti-technology attitudes (Kurtz, 1994;Park 1996); they believe in a holistic view of health (Anyinam, 1990); they reject authority, especially scientific authority, and demand participation (Taylor, 1984; Easthope, 1993; Riessman, 1994); and they believe in individual responsibility (Cassileth, 1989; Coward, 1989). Alternative practitioners, such as Occupational therapist, commonly use natural and non-invasive treatments, espouse a holistic view of health, allow patients participation in the process of healing (Aaskter,1989), and stress that health comes from within the individual and it is ultimately the responsibility of the individual to achieve a desired state of health. (Coward, 1989) Sussman (p.31) looks at the holistic concept of behaviour stresses an organic and/ or functional relationship, a continuing interaction, and a fundamental interdependence among the traditionally defined parts or areas of human behaviour. Accordingly, the understanding of any aspect of human behaviour or any human problem involves consideration of the potentialities and limitations inherent in human biology; the characteristic ways of feeling, thinking, acting, and relating to other that comprise personality; the nature of physical environment, including natural resources, topographical features, and the man-made environment; the social nature of and the impact of significant social or reference groups; the nature of culture, its potentialities and the limitations it imposes; and the significance of time and mans orientation to time as a key factor in the ordering and regulation of behaviour. In many respects, the holistic philosophy represents a reaction against certain forms of fragmentation and compartmentalisation which have characterised both scientific investigation and the approach to human problems during the first half of the 20th century. Implementation of the holistic approach is seen today in the growing body of research which crosses traditional discipline lines and in the renewed emphasis on comprehensive medicine, comprehensive mental health, and a comprehensive approach to a broad spectrum of human problems including delinquency, alcoholism, unemployment, disability etc. the holistic approach is compatible with an increasing awareness of the tendency for various forms of pathology to occur in clusters. Medical Care and Professionalism Medical care, once dominated by a restricted orthopaedic orientation, is now based on a growing recognition of the basic relationship between the anatomical, physiological, biochemical, and psychological functioning of the human body, and the reciprocal relationship between a disabled persons body functioning manifestation of his personality and his capacity to fulfil basic roles in job, family and community. In contrast, look at the study undergone by à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦ All participants found that Occupational therapy was being underutilised. One reason provided for this was the lack of understanding about the role of OT by other staff members. Participants of this study felt that the perspective of OT as more of a rehabilitation service and less as a holistic service had an impact on the low use of OT, this being within a hospice setting. They found OT was often defined too much by exercises or functional tasks, and not recognising functional tasks become even more critical to someone who is becoming weaker and weaker and is in the process of dying. The hallmark of professionalism has been accountability for the application of expert knowledge to the service of others (Goode, 1960) Accountability includes both the obligation to answer questions regarding decisions and/or actions and the availability and applications of sanctions for illegal or inappropriate actions and behaviours (Brinkerhoff, 2004) health professionals have historically been accountable to their regulatory bodies for their autonomous exercise of professional judgment in determining services provided (Abbott, 19988). In recent years, the traditional approach to health professional accountability has been called into question for several reasons, one being escalation health expenditures (Degeling, 2000). Because all professional decisions related to health care have financial implications, this control has frequently translated into greater limits on professional practice. Occupational Therapy and Rehabilitation Sussmans (1965) work on the sociology of rehabilitation is well recognised and has the support of the American Sociological Association. The book emerged from a conference on Sociological Theory, Research and Rehabilitation held in Carmel, California in March 1965. According to Sussman, public interest in the concept of rehabilitation has greatly intensified in recent years. The term rehabilitation is being broadly applied to many kinds of disabling human problems, including physical disability, mental illnesses, mental retardation, alcoholism, drug addiction etc. Rehabilitation is used in both a limited and very comprehensive sense. It may refer to services concerned with education, physical functioning, psychological adjustment, social adaptions, vocational capabilities, or recreational activities. Occupational therapy rehabilitation can involve one of several types of therapy, used together or separately, to help patients enter or re-enter the workforce. This can include physical therapy, counselling, and job training. The overall goal of these therapies is to remedy any situation that may cause a patient to fail to perform in both personal and professional environments. Physical occupational therapy rehabilitation may be needed if a patient has been either injured or born with a physical handicap which interferes with everyday living. This can include the re-training of certain major muscle groups as well as education in using a wheelchair or other mobility aid to perform simple and complex tasks. In some more severe cases, employment may never be a possibility due to extreme physical limitations. For these patients, occupational therapy rehabilitation may act to teach them tasks as basic as eating with a fork and spoon or bathing themselves. Counselling for mentally ill, aggressive or depressed patients is also a type of occupational therapy rehabilitation. Often, an employer will require specific workers to undergo this type of treatment to help them interact more efficiently with co-workers, stay motivated on the job, or to fully rehabilitate them after a traumatic experience or depressive episode. This helps patients overcome emotional issues that may hinder job performance or social development, and allows them to effectively express issues and interact with customers or clients. Sometimes occupational therapy rehabilitation involves specific job training courses. This method may be used for mentally handicapped or brain damaged individuals, or those who have lost employment due to emotional or mental issues. Job training helps patients learn specific job related skills including how to perform basic job duties like lifting or typing, as well as how to interact with co-workers and customers. In some cases, an occupational therapist or counsellor may be hired to settle a dispute or problem between colleagues or groups within a workplace. This may include argumentative co-workers who are aggressive to the point of hindered job performance. In these situations, the therapist will teach proper coping methods for dealing with anger and jealously in the workforce in the form of individual counselling sessions, seminars, or group therapy meetings. Therapists and doctors often work together in occupational therapy rehabilitation for their patients. A combination of therapies and medications may be used in order to obtain full rehabilitative results. The primary goal of these tactics is to allow patients to live and work as normal as possible in society. Disability and Rehabilitation When looking at Occupational therapy in terms of rehabilitation, the experts agree that effective rehabilitation of the physically disabled involved helping the client to regain physical and social functions lost through injury or disease. Haber (1973) argues that disability should be conceptualised and measured by functional in capacities. Disability is then the inability to perform usual role activities as a result of a physical or mental impairment (loss of function) of long-term duration (Haber and Smith, 1971) One view of rehabilitation success is taken by Ludwig and Adams (1968) and Diamond et al. (1968) who use patient cooperation and participation in treatment as a measure of outcome. Acceptance of the sick role implies that the patient cooperate and participate in the treatment process as outlined by the experts so that he can get better (Parsons, 1951; 1975). In this context, the good and successful patient is judged to be the person who complies with the sick role. Consequently, rehabilitation success might be an artefact. There is no evidence to show that staff members tend to concentrate their efforts on those patients that they value highly or think have the best chance of demonstrating improvement (Kelman, 1964). However, appearance of patient motivation and cooperation in the rehabilitation settings does not accurately predict independent living after discharge (Kelman and Wilner, 1962). According to Nagi, when trying to define the concept of disabilities looks at the terms impairment and disability. He explores these terms by looking at how every individual lives within an environment in which he is called upon to perform certain roles and tasks. The ability and inability of people can be meaningfully understood and estimated only in terms of the degree of their fulfilment of these roles and tasks, when an individual is described as being unable the description in incomplete till it answers the question, unable to do what?. In this sense, ability-inability constitutes an assessment of the individuals level of functioning within an environment. Two categories of inability can be delineated on the basis of the time of onset. First are congenital inabilities. There are inborn limitations that are the result of anatomical malformations, physiological abnormalities, mental deficiencies, and/or general constitutional inadequacies. To be sure, abilities of all humans are subject tot limitations. Further more, Nagi argues, people differ greatly in degree of ability-inability without nec essarily suffering from an active disorder or a residual impairment. However, although the cutting point between able and unable is hard to distinguish, the more severe conditions are usually recognised. The OASI program have defined disability as the inability to engage in any substantial gainful activity by reason of a medically determinable impairment that is expected to be of long-continues and indefinite duration or to result in death. Potential for rehabilitation indicated a prognostic evaluation of the levels of functioning the individual is capable of reaching under certain circumstances. The assessment of ability-inability is obviously a necessary step toward the evaluation of rehabilitation potential. Occupational therapists ask patients to perform a variety of tasks that would require the use of different types of tools and equipment. Information sought in this evaluation includes an assessment of the following attributes: the quality and quantity of work done, physical and interpersonal work adjustment. Experience and skills, the degree to which the impairment disables the individual in the performance of certain tasks. The rehabilitation potential of the patient. Occupational therapists are informed by the physician when the risk to a patients health precluded certain tasks or the whole occupational evaluation. Criticisms. Throught the mobilisation of the efforts of a highly trained team of medical including occupational therapists, rehabilitation envisions the maximum physical, mental, social, vocational and economic recovery possible. While the goals are attained many very with each individual case, Julius Roth has questioned whether such goals should legitimately be set by the patient or the therapist. The ultimate success of the program rests upon a remarkably intriguing interplay of the biogenic, sociogenic, and psychogenic components of human behaviour The delivery of Occupational Therapy Looking at where and how occupational therapy is delivered, it is delivered in Primary and Secondary Care following the patients journey and is governed by care pathways which include formal and informal carers.  The service is equitable in access and is provided from cradle to graves. Primary care is provided for patients at first contact with the health service. By this very nature it must be generalist, being able to cope with whatever problems arise. General practitioners are the traditional primary care doctors but in recent years we have seen rise to a primary care team, including Occupational Therapist, Physiotherapist and speech therapist to name a few, offering a wider range of health professionals and their respective skills. The World Health Organisation states in its blueprint for Health for All by the Year 2000 that there should be a special emphasis on primary health care services, particularly in developing countries in which funding is even more limited. This recent emphasis on the importance of health care has further improved its status in the medical world. This is particularly true in areas in occupational therapy when there is a focus on for example, elderly in residential care, and other community care related interventions. According to Tussing Wren (2006) literature on primary care indicates a need for the following, all of which are weak or absent in the Irish system: A primary care system which addresses the health needs of a mainly healthy population rather than concentrating on intervention in episodes of illness, an emphases on disease management for the chronically ill, supportive of self-care and home care, stronger evidence-based medicine, with appropriate protocols and guidelines, peer review and quality assurance, primary care infrastructure, supportive institutions, skilled substitutions, and GP interface. On the other hand secondary care is usually specialist services that require beds, and sometimes expensive equipment. Therefore it is usually based in hospitals. For example, stroke patients may be referred to Occupational Therapist by physicians after hospitalisation. Occupational therapist might then work with them in a rehabilitation centre using specific equipment to regain independence. Emerging Services Within recent years, much emphasis has been given to the development and expansion of a variety of out of hospital services for the chronically ill. However, such demonstrations continue to be slow to develop. Among the many issues involved in these attempts are those concerning the roles to be assumed by hospital or by community based agencies in relation to the provision of community care for those disabled patients who no longer require active hospital in-patient treatment. The studyà ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦ was undertaken in order to define a more appropriate hospital role in relation to the continuing needs for rehabilitation care of a chronically ill and disabled population discharge to the community following extended hospital rehabilitation treatment. It evolved against a background of rather pessimistic clinical impressions and retrospective research probes which emphasised this populations failu re to maintain optimum health and social functioning in the community despite the achievement of these level while in the hospital. More specifically, concerns centred on this populations high rate of rehospitalisation, its deterioration in social functioning and its failure to use or to receive needed health and health related services while in the community. Acute Care Occupational therapy plays an essential role in the acute care hospital and in other medically related facilities from the rehabilitation hospital, to sub acute sites, to extended care facilities, to the facilities of the future. Though there are issues when it comes to acute care, Torrance, (1993) states that with increasing technology and quicker discharge, the need for therapeutic occupation increases. Occupational therapists are needed to work with patients in problem solving self-care occupations amidst the constraints of the tubes, monitors and fixators; to activate patients at risk because of the deleterious effects of bed rest; to help patients and caregivers plan realistically from what the patients will do and for how the patients will live and care for themselves after discharge but before healing; and to assess patients quality of life before and after hospitalisation. Nelson (1997:20) gives an example: For an example of the importance of therapeutic occupation in an acute care setting, consider a 5 month old girl born with neuromuscular disease of unknown etiology. The disease is characterised by the total absence of many of the proximal muscles, including those responsible for respiration. Picture her with multiple intubations for respiration and nutrition and with life-support monitors. The occupational therapist carefully removes her from the crib and bounces her gently while talking to her in high-pitched, rhythmical tones. In response to this occupational form, the infants adaptions are to learn to use the muscles controlling her vocal cords as she imitates the therapist; to learn to use the remaining muscles in her left arm as she grabs the therapists keys; and most of all to begin to learn that she too has a legitimate place in the human family. The therapist next places a piece of cloth playfully over the childs face, as in our prior example of the importance of peek-a-boo in healthy development. Like a health baby, this baby too removes the cloth and laughs. Despite the high technology setting, this baby also needs to encounter the occupational form of peek-a-boo in order to develop a sense of self and a sense of other. Therefore Occupational models of practise are needed for the acute care hospital for patients at all points on the lifer span. Since many health problems require a level of medical treatment and personal care that extends beyond the range of services normally available in the patients home, modern society has developed formal institutions for patients care intended to help meet the more complex health needs of its members. Here, much of an occupational therapist work is carried out. Usually in rehabilitation centres within the hospital. Looking at the hospital in more detail, the work of Cockerham (2007) draws on how it is the major social institution for the delivery of health care in the modern world, and how it offers considerable advantages to both patients and society. From the individuals point of view, the injured or sick person has access to centralised medical knowledge and the greatest array of technology within the hospital, and from the standpoint of society, as Renee Fox and Talcott Parsons (1952) argue, that when patients are within the hospital they are protecting their family from many disruptive effects of caring for the ill in the home and operates as a means of guiding the sick and injured into medically supervised institutions where their problems are less disruptive for society as a whole. Many other concepts of Parsons have been criticised, taking his concept of the sick role, it has been argued that Parsons model cannot be applied to chronic illnesses from which patients cannot recover. More significantly, it had been shown that access to the sick role is rather more problematic that Parsons model assumes. It has been suggested that parsons is really talking about a patient role rather then a sick role as there is a distinction between patients subjective experiences of illness and being objectively defined by doctors as having a disease. It is true to say Occupational therapy rejects a lot of Talcott Parons sick role ideas, who believes that when an individual is in the sick role he or she is exempt from responsibility for the incapacity, as it is beyond their control, and is also exempt from normal social role obligations. While this is true to say, Lober (1975:214) observes that while the patient is in the hospital there is an idea of voluntary cooperation , one to one intimacy, and conditional permissiveness, for example, being temporarily excused from normal social activities on the condition of seeking medical advice and care. Coe (1978) has also argued that acceptance is the most common form of patient adjustment to hospital routine and the most successful for short-stay patients, which most patients seeking Occupational therapy are, as the main aim is to get the patients back into society. Chronically Ill and Care According to Oliver (1996), as societies modernise the burden of disease is shifting from acute to chronic long-term illness and disability. While clinical medicine can treat many of these chronic conditions, it cannot cure many of them, and thus more and more people are spending a greater proportion of their lives coping with illness. Occupational therapist deal with many terminally ill patients. According to à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦.. Individuals with terminal illness face a number of problems related to social, emotional, spiritual and their physical well-being. Some individuals have expressed that the feeling of being a burden to family and friends is more distressing than physical pain (Lloyd, 1989). Carey, 1975 looks at how these individuals with terminal illnesses find the biggest challenges in looking for satisfactory meaning in their new life situation whole facing mortality. Care for these patients has come along way, as in the past the care had primary focus on alleviating only the physical distress of the illness. Kubler-Ross (1997) describes how physicians, who are held back by their own views and feeling on death, are often unable to reach out to their dying patients to provide them with care and comfort. Therefore death in the past was almost seen as a failure of medicine. This ideology began to change with the emergence of the hospice in 1967 by De Cicely Saunfers, who founded St. Christophers hospice. Today we can recognise the hospice as a specialised facility for the care of dying patients that supports them in living life fully and comfortably while confronting death (National Hospice Organisation, 1996). The American Occupational Therapy Association (AOTA) (1998) states the following inn relation to occupational therapy and the hospice: The AOTA affirms the right of a dying person to have access to a caring community within the health care system and believes in the need for personalised care of the dying individual throughout the course of a terminal illness. Occupational Therapy is based on the belief that all individuals engage in occupationsà ¢Ã¢â€š ¬Ã‚ ¦ Occupational therapy practitioners are uniquely qualified to help the dying person continue to engage in meaningful daily occupations within the hospice community of care. (p.872) When a patient who has a terminal illness continues to lose their ability to care for themselves and carryout usual daily activities, fostering the patients independence in self-care, work, and leisure usually becomes a top priority of intervention (Holland Tigges, 1981; Tigges, 1983; Tigges Marcil, 1988). Tigges (1983) explains a framework that looks at the human need of mastery-productive use of tie, energy, interest, and attention, this is also known as the occupational role of performance paradigm (9.163). Although some individuals with terminal illnesses are able to maintain many of their usual roles, its not always true for others. According to Gammage, McMahon, and Shanahan (1976), occupational therapist have a unique role in assisting patients to accept their new role as an individual with an illness and relinquish old occupational roles. Not only do occupational therapists focus on roles los

The Big Sleep - The Movie and The Book :: Movie Film comparison compare contrast

The Big Sleep - The Movie and The Book One would think that it would be quite easy to adapt a novel to a screenplay; after all, what is there to do but turn the dialogue into lines and description into set design? However, common sense, aided by the horrifying number of absolutely awful adaptations, dictates that it simply is not that easy. When moviegoers have problems with a film adaptation of a book, their complaints tend to lie in the tendency of the creators of the film to change elements of the story: plot, character, and the like. It would seem, then, that the best way to make a successful adaptation of a novel would be to just stay as true as possible to every detail mentioned in the book. However, staying as true as possible to plot points, character type, and the like may be the best way to a horrendous adaptation. In moving from the printed page to the silver screen, moviemakers must be aware that they are not simply reproducing a narrative&emdash;they are changing the medium by which the narrative is presented. Oddly enough, cinema lends itself easily to some of the tenets of writing well: namely, the command of, "show, don't tell." In cinema, there is no option, really, of telling, "the details are not asserted as such by a narrator but simply presented." (Chatman 406). The use of a voiceover, of course, is an option, but even the voice of an omniscient narrator cannot stop the viewer from seeing the images and interpreting what he sees. In movies, the viewer does his own telling. The very nature of The Big Sleep, then, makes adaptation difficult. The entire narrative is described by a character within the story space: Marlowe tells us the entire story. Our view of the plot, then, is clouded by Marlowe's sight. Being a character within the story space, he has his own feelings and his own reactions to what happens to and around him, and he passes those reactions&emdash;albeit unconsciously&emdash;to the reader, who, also unconsciously, picks up on them. Marlowe does not act the role of mediator, though, in the film version of The Big Sleep.

Should Medicaid Pay for Abortion

Should Medicaid pay for abortion? This is a very touchy subject and one that has been in the newspapers for months now. It is also the main reason that the passing of the historic health was postponed for the amount of time that it was. I think that even though abortion is a touchy subject and won that has been a main topic since â€Å"Roe vs. Wade in 1973,† I think that is a very important topic and one that will always be discussed for much more time. I think that abortion should be legal and be the decision of the parties involved to make the decision on whether to have one or not.Also, I believe think that abortion should be covered by the tax payers in the case o rape or incest because both of those instances could result in a very tough life for the baby. Either the child will be hated by its mother because every day she looks at him/her it reminds her of her rapist, or the child is born with birth defects. To thoroughly make a good decision on where you stand with the a bortion topic, I think that you must first find out what abortion actually is.Abortion is the induced termination of a pregnancy with destruction of the embryo or fetus, any of various procedures resulting in the termination of a pregnancy, cessation of normal growth, especially of an organ or other body part, prior to full development or maturation, and the premature ending or abandonment of an undertaking. Abortion procedures include manual vacuum aspiration and dilation and suction curettage, both of which can be performed in early pregnancy.The social acceptability of abortion as a means of population control has varied from time to time and place to place throughout history. â€Å"It was apparently a common method of family limitation in the Greco-Roman world, but Christian theologians early and vehemently condemned it. It became widely accepted in Europe in the middle Ages. Severe criminal sanctions to deter abortion became common in the 19th century, but in the 20th century those sanctions were gradually modified in many countries. † In the U. S. the 1973 Roe v.Wade decision had the effect of legalizing abortion during the first three months of pregnancy; states were able to implement restrictions on access to abortion after the first trimester, though within constraints set by the courts. Since that decision, there has been a fierce debate between supporters and opponents of a liberalized abortion policy. As you see this is something that has been debated for centuries upon centuries. I have read many articals on abortion and how the procedure is actually conducted.The procedure seems to be very gruesome, that is why I can understand why some people like rep. Bart Stupak are diehard pro-life supporters. If you can recall Bart Stupak who is a senator from Michigan (our own state) was the democrat who along with twelve other pro-life democrats held up the passing of the healthcare bill with his votes until President Obama agreed to sign an executi ve order stating that government funding will not go to covering abortion in this new health care bill. After words Stupak said â€Å"We stood strong,† said Stupak. â€Å"We stood on a principle. Stupak’s argument really goes all the way back to Roe v. Wade. After Roe v. Wade decriminalized abortion in 1973, Medicaid covered abortion care without restriction. In 1976, Representative Henry Hyde (R-IL) introduced an amendment that later passed to limit federal funding for abortion care. Effective in 1977, this provision, known as the Hyde Amendment, specifies what abortion services are covered under Medicaid. Over the past two decades, Congress has debated the limited circumstances under which federal funding for abortion should be allowed.For a brief period of time, coverage included cases of rape, incest, life endangerment, and physical health damage to the woman. However, beginning in 1979, the physical health exception was excluded, and in 1981 rape and incest excep tions were also excluded. In September 1993, Congress rewrote the provision to include Medicaid funding for abortions in cases where the pregnancy resulted from rape or incest. The present version of the Hyde Amendment requires coverage of abortion in cases of rape, incest, and life endangerment. The first challenges to the Hyde Amendment came shortly after its implementation.The Supreme Court has held that the Hyde Amendment restrictions are constitutional and that states participating in Medicaid are only required to cover abortion services for which they receive federal funding rather than all medically necessary abortions. Challenges under state constitutions have been more successful. Several lawsuits have been brought in individual states arguing that state constitutions afford greater protection for privacy and equal protection than the federal Constitution. The Hyde Amendment affects only federal spending. States are free to use heir own funds to cover additional abortion se rvices. For example, Hawaii, New York, and Washington have enacted laws funding abortions for health reasons. Other states, such as Maryland, cover abortions for women whose pregnancies are affected by fetal abnormalities or present serious health risks. These expansions are important steps toward ensuring equal access to health care for all women. Prior to the 1993 expansion of the Hyde Amendment, thirty states chose not to use their own Medicaid funds to cover abortions for pregnancies resulting from rape or incest.Initially, a number of states expressed resistance to comply with the expanded Hyde Amendment, and presently thirteen states are under court orders to comply and cover rape and incest in addition to life endangerment. â€Å"Every court that has considered the Hyde Amendment's application to a state's Medicaid program since 1993 has held that states continuing to participate in the Medicaid program must cover abortions resulting from rape or incest in order to be compli ant with the Hyde Amendment, regardless of state laws that may be more restrictive. Federal funding has been covering abortion for years and according to the Hyde Amendment it covers incest and rape. My research has also led me to see that Michigan is one of twenty seven states that receive funding under the Hyde Amendment. This means that one of the states that use federal funding for abortion in special cases has the main representative that is arguing that exact system. This is kind of ironic to me. If the federal funding is there and actually has been there for seventeen years what the point of arguing the bill that will eventually save the government money.I have found some interesting information that if looked at maybe by some of our politicians they would not cause such a big fuss like Stupak and some other extreme conservatives like Sarah Palin about a the health care bill that not only is in the best interest of the people but also the best interest of the government in te rms of the budget but also the insurance companies who now will have more policies out there to bring in more revenue. Here are some interesting facts that I found about what type of women have abortions and why. Women with family incomes less than $15,000 obtain 28. 7% of all abortions; Women with family incomes between $15,000 and $29,999 obtain 19. 5%; Women with family incomes between $30,000 and $59,999 obtain 38. 0%;Women with family incomes over $60,000 obtain 13. 8%. † The reason women have abortion are as follows, â€Å"1% of all abortions occur because of rape or incest; 6% of abortions occur because of potential health problems regarding either the mother or child, and 93% of all abortions occur for social reasons (i. e. he child is unwanted or inconvenient). † So why not allow the health care bill to cover abortion? If the bill is basically just going to keep the Hyde Amendment rule in place or maybe take it another step forward and require police reports on alleged rapes and incest it really will not make a difference. If only one percent of all abortion are due to rape or incest, that amount of spending will not even dent the federal funding. I think more money is spent by politicians on their private jets that take all over the United States just to make appearances.While abortion remains perhaps the most contentious issue in American politics, what is one person’s principled stand is another’s crime against humanity. Abortion is a decision that should be made by the person going through the process not some politician from Texas for example who lives in a ten thousand square foot home and makes probably a million dollars a year after kick backs. Also if the system of states covering under the correct circumstances has been working for almost twenty years then I say why change it.Many times people let their emotions and personal feeling make their decisions when all they have do is put themselves in the position of the women who was raped, or the male is out of the picture and the mother will not be able to financially support a child and the child might end up in a dumpster, in the street or living in foster homes its whole life. I look at this way and I’m going to state a question to some of these people who think federal funding should not pay for this. Financially speaking as a nation, Is it financially better to cover a $500 dollar procedure once or pay for Medicare, housing, and food for eighteen years?From doing the basic math I think the $500 is a lot cheaper. The United States is a business. And just like any other business it needs money to survive. To maintain that money it has a budget, and that budget at this point is in a major deficit. This bill will save trillions of dollars over the next fifteen years imagine how much more money they could save all states allowed the lower income poverty striking women to have abortion under the state insurance, trillions more would be sav ed. Basic math is the key to answering this, in the end its all business.WORK CITED 1. Gregg Cunningham, WHY ABORTION IS GENOCIDE Winter 2000 2. AMERICAN GOVERNMENT TEXT BOOK 3.

Free Essays on A Bum Rap

A Bum Rap It’s interesting how most people tend to categorize others into groups by certain personality traits. At one time or another, everyone is guilty of this kind of stereotyping as a means to describe someone else. In many instances, the person being evaluated is not even known. Who are only being judged on appearance, or by a quick glance from across the room. In these cases, the shy person is typically evaluated unfairly, compared to the outgoing person, who gives others the opportunity to make accurate impressions of them. Curiously, the shy person is generally branded with an unflattering reputation, even though they are quiet and well-mannered individuals. Shy people are very attentive and trustworthy listeners. A person can tell them anything, even their deepest secrets. They will give their undivided attention to a person, revealing nothing of what is spoken. However, a outgoing loudmouth will interrupt at any given chance to repeatedly force their uniformed opinions on anyone who will listen. They cannot be trusted. The urge to gossip is too tantalizing for them to pass up. The shy person is wrongfully bestowed with the title of snob, simply because they value other’s privacy, as well as their own.

Biography of Louis Pasteur, Health Sciences Pioneer

Biography of Louis Pasteur, Health Sciences Pioneer Louis Pasteur (December 27, 1822–September 28, 1895) was a French biologist and chemist whose breakthrough discoveries into the causes and prevention of disease ushered in the modern era of medicine. Fast Facts: Louis Pasteur Known For: Discovered pasteurization, studies of anthrax, rabies, improved medical techniquesBorn: December 27, 1822 in Dole, FranceParents: Jean-Joseph Pasteur and Jeanne-Etiennette RoquiDied: September 28, 1895 in Paris, FranceEducation: Collà ¨ge Royal at Besancon (BA, 1842; BSc 1842), Ecole Normale Supà ©rieure (MSc, 1845; Ph.D. 1847)Spouse: Marie Laurent (1826–1910, m. May 29, 1849)Children: Jeanne (1850–1859), Jean Baptiste (1851–1908), Cà ©cile (1853–1866), Marie Louise (1858–1934),  Camille (1863–1865) Early Life Louis Pasteur was born December 27, 1822 in Dole, France, into a Catholic family. He was the third child and only son of  poorly educated tanner Jean-Joseph Pasteur and his wife Jeanne-Etiennette Roqui. He attended primary school when he was 9 years old, and at that time he didnt show any particular interest in the sciences. He was, however, quite a good artist. In 1839, he was accepted to the  Collà ¨ge Royal at Besancon, from which he graduated with both a BA and a BSc in 1842 with honors in physics, mathematics, Latin, and drawing, gaining. He later attended the prestigious Ecole Normale Supà ©rieure  to study physics and chemistry, specializing in crystals, and obtaining the French equivalents of an MSc (1845) and a Ph.D. (1847). He served briefly as a professor of physics at the Lycee in Dijon, and later became a professor of chemistry at the University of Strasbourg. Marriage and Family It was at the University of Strasbourg that Pasteur met Marie Laurent, the daughter of the universitys rector; she would become Louis secretary and writing assistant. The couple married on  May 29, 1849,  and had  five children: Jeanne (1850–1859), Jean Baptiste (1851–1908), Cà ©cile (1853–1866), Marie Louise (1858–1934), and Camille (1863–1865). Only two of his children survived to  adulthood: the other three  died of typhoid fever, perhaps leading to Pasteurs drive to save people from disease.   Accomplishments Over the course of his career, Pasteur conducted research that ushered in the modern era of medicine and science. Thanks to his discoveries, people could now live  longer and healthier lives. His early work  with the wine growers of France, in which he developed a way to pasteurize and kill germs as part of the fermentation process, meant that all kinds of liquids could now be safely brought to market- wine, milk, and even beer. He was even granted U.S. patent 135,245 for Improvement in Brewing Beer and Ale Pasteurization.   Additional accomplishments included his discovery of a cure for a certain disease that affected silkworms, which was a tremendous boon to the textile industry. He also found cures for chicken cholera, anthrax in sheep, and rabies in humans. The Pasteur Institute In 1857, Pasteur moved to Paris, where he took up a series of professorships. Personally, Pasteur lost three of his own children to typhoid during this period, and in 1868, he suffered a debilitating stroke, which left him partially paralyzed for the rest of his life. He opened the Pasteur Institute in 1888, with the stated purpose of the treatment of rabies and the study of virulent and contagious diseases. The Institute pioneered studies in microbiology, and held  the  first-ever class in the new discipline in 1889. Starting in 1891, Pasteur began to open other Institutes throughout Europe to advance his ideas. Today, there are  32 Pasteur institutes or hospitals in 29 countries throughout the world. The Germ Theory of Disease During Louis Pasteurs lifetime it was not easy for him to convince others of his ideas, which were controversial in their time but are considered absolutely correct today. Pasteur fought to convince surgeons that germs existed and that they were the cause of disease, not bad air, the prevailing theory up to that point. Furthermore, he insisted that germs could be spread via human contact and even medical instruments, and that killing germs through pasteurization and sterilization was imperative to preventing the spread of disease. In addition, Pasteur advanced the study of virology. His  work with rabies led him to realize that weak forms of disease  could be used as an immunization against stronger forms.   Famous Quotes Did you ever observe to whom the accidents happen? Chance favors only the prepared mind. Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world. Controversy   A few historians disagree with the accepted wisdom regarding Pasteurs discoveries. At the centennial of the biologists death in 1995, a historian specializing in science, Gerald L. Geison  (1943–2001), published a book analyzing Pasteurs private notebooks, which had only been made public about a decade earlier. In The Private Science of Louis Pasteur, Geison asserted that Pasteur had given misleading accounts about many of his important discoveries. Still, other critics labeled him a fraud. Death Louis Pasteur continued to work at the Pasteur Institute until June 1895, when he retired because of his increasing illness. He died on September 28, 1895, after suffering multiple strokes. Legacy Pasteur was complicated: inconsistencies and misrepresentations identified by Geison in Pasteurs notebooks show that he was not just an experimenter, but a powerful combatant, orator, and writer, who did distort facts to sway opinions and promote himself and his causes. Nevertheless, his accomplishments were tremendous- in particular his anthrax and rabies studies, the importance of handwashing and sterilization in surgery, and most importantly, ushering in the era of the vaccine. These accomplishments continue to inspire and cure millions of people. Sources Berche, P. Louis Pasteur, from Crystals of Life to Vaccination.

Exam over the history of Reform and Power of the Elites essays

Exam over the history of Reform and Power of the Elites essays American people hear about reform and ideas surrounding reform every election year. Americans around election time begin to hear new policies that an elected candidate would like to enact or reforms that they will pass when in power. These reforms are made to seem like the key to a brighter tomorrow for everyone. Americans begin to live with a new hope, that this one person will get elected and in taking office make dreams come true. In most cases the reforms that the politicians speak of are thrown by the waste side even if they are elected, and when they are enacted they usually fail to satisfy the American people. When one examines reforms that have come about since the 1930s one can see many trends in American desires and how they were are were not met when reforms are set into motion by the government. When speaking of reform in government it is necessary to examine the New Deal set into motion by Roosevelt. Roosevelt enacted a whirlwind of political reform with the hopes of picking America out of unemployment and depression. His aid to the economy, to the jobless, to the farms followed quickly after his election. The New Deals first act was the Emergency Banking Act established on March 9th 1933, six more were to immediately follow. The acts provided funds for farmers, jobs for the unemployed youth, and relief for the impoverished. With this being said, one would think that the new deal programs were among the most popular reforms to date. This was not the entire case. Some programs such as the Civilian Conservation Corps won wide popularity, others did not. Those farmers that did not have much land did not qualify for atonement offered to the larger field farmers. Business reform was also met with numerous conflicts; those in power companies did not want to suffer with increas ed competition and fought New Deal reforms. Moving form the 30s to the 60s is a jump in time but the number of reforms ena...

Course Concept Redesign - Coursework Example In addition, the new student can present their views by commenting on the video and get feedbacks from their fellow students. The search strategy used article databases in identifying the three sources on the concept of the greenhouse effect and climate change. In the first source, Reinfried and colleagues argue that it is difficult changing student’s everyday ideas of the greenhouse effect. The challenge that environmental education face is creating of instructional setting aimed to foster student’s conceptual understanding of the concept of the greenhouse effect. In facilitating students conceptual development regarding the greenhouse effect, it is critical to design learning materials that promote active cognitive learning and focused on achieving deep understanding of the concept. Reinfried et al., present in the article, a developed learning material based on the theory of understanding and reasoning. They compared the efficacy of the design with standard learning materials by using pre-, post and follow-up test. In examining the student’s understanding and knowledge acquisition o ver the three measurement test, Reinfried et al., used both qualitative and quantitative methods. The study outcome demonstrated that the group instructed according to the design focused on in-depth learning had better knowledge gains and retention compared to the group taught using standard learning materials. The strength of the article, therefore, is that it provides an instructional design that engages learners in high cognitive activities, which enhance deep conceptual understanding of the abstract and complex concept of the greenhouse effect. However, the article has a weakness in presenting a comparative study conducted for a long a duration of time because conceptual changes require much time to develop. In the second source, Ogden et al., points that the extent of climate change affects human health in a

Social Responsibility of McDonald's Case Study Example | Topics and Well Written Essays - 500 words

Social Responsibility of McDonald's - Case Study Example Developments in science and technology that enable the creation of new food products and the diminishing consumer involvement in preparing food products on their own are two prominent factors. These two factors need to be handled by the food industry with sensitivity to society for the business enterprises in this sector of industry to live up to the ethical expectations in the manner in which they do business (Early 2002).  McDonald's has recognized the need for providing organizational leadership to act responsibly in the perspective of society. This is reflected in the words of Jack M. Greenberg Chairman and Chief Executive of McDonald's. â€Å"  "Social responsibility is not a project or a program. Acting responsibly is the way McDonald's does business†. Thus organizational leadership for the manner in which McDonald’s attempts to do business in a socially responsible manner begins with top management and percolates to all segments of the organization. This has seen environmental and market place initiatives come into place. In partnership with the Centre for Environmental Leadership in Business McDonald has targeted sustainable agriculture and conservation practices and standards within the McDonalds supply chain. This is one of the environmental initiatives. On the marketing initiative front, McDonald’s has formed a consultative body to ensure humane treatment of animals and birds in the farms associated with the supply. Food safety is an issue of serious concern for McDonald's and maintains a high degree of â€Å"professional responsibility† and â€Å"deep commitment† to food safety requirements.  

Tim Hortons Assignment Example | Topics and Well Written Essays - 500 words

Tim Hortons - Assignment Example Training needs are assessed through group interactions and observations by the human resource departments. The methods and techniques of training must be scientifically objective. This requires appropriately scaling the individual employee's performance through scores such as "needs improving, good, and excellent" (Chapman, Alan; 2009). Teams work best when they are given specific projects to work on. The selection and structure of teams depend on the size of the project and number of qualified personnel required in each team. They are trained on the basis of the job requirements and they are appraised through tests and observation by superiors as well as the human resource departments (Chaudron, David). Our business follows various strategies. We recognize good performance with a good back pat. We also recognize good performances through cash prize, good performance certificates and promotions (Employee Motivation & Job Satisfaction, 2009). Business hires a flexible leader. The flexible leader is a manager as well as leader. He knows a leadership is not manager and manager is not a leader. At the same time, he is capable of bonding with his men on a personal and emotional level. He has business targets. He meets his business targets using personal and emotional skills (Fletcher, Douglas; 2010).

The protagonist of the play is Yuranosuke, who is the chief retainer of Hangan’s household and wants to fulfill his master’s dying wish to avenge him. Yuranosuke is assisted by a band of retainers, who have sworn allegiance to him and go to severe extremes to help him accomplish his mission; Kampei is one of the most notable retainers, who is unable to make any substantial contribution to the assassination plot, but his devotion to Hangan still moves all the other retainers to include him in the list. Yuranosuke’s loyalty to his master is exhibited through his undying resolve to exact revenge on Morono. Even though, a vendetta in Tokugawa Japan is punishable by ritual suicide, but the retainers remain resolute under Yuranosuke. They are ready to lay dow n their lives for their Master Hangan, which is a sure sign of their loyalty. Moments before Hangan is ordered to commit Seppuku; ritual suicide, he asks Yuranosuke, to take his dagger after his death, which clearly indicates his wish to be avenged. Yuranosuke, who is both aggrieved and determined to take revenge upon his master’s tormentor, licks the blood off his master’s dagger ; this act to show his dedication to the cause (p. 23). He gathers all the other retainers, who are devoted to cause and secretly starts off the vendetta. The vendetta is a secret mission; therefore he takes every measure to protect it from Morono, who was already suspicious of it. The strength of Yuranosuke’s resolve to proceed with the assassination is very clear as he is willing to do anything to prevent his plan from getting compromised. He even eats fish on his master’s death anniversary; which is considered to be a great religious taboo, but he breaks it just so he could p rotect his master’s last wish. After their master’s death, the retainers were left without a leader and Yuranosuke, being the chief retainer in Hangan’s household gained the leadership by default. All his fellow retainers were quite dedicated to him and had they not sworn complete allegiance to him, they would not have been able to bring their plans to fruition. The case of the merchant in the play further underscores the lot’s loyalty to Yuranosuke; the merchant had been supplying them with weapons in order to help them with the plot. The merchant had sent his wife off to live with her parents in order to prevent her from finding out about the plan, but in so doing he earned the ire of his father-in-law, who wanted her daughter to marry someone of wealth and constantly forced the merchant to divorce her. Upon seeing his ordeal, Yuranosuke intervenes and cuts off the woman’s lock and prevents her remarriage. This trait is reflected in all of Hangan ’s retainers, particularly Kampei as well. He suffers from a lingering guilt for he had abandoned his post in order to meet his lover, with whom he had scheduled daily trysts and when Hangan was being provoked into drawing his sword, he had been with his lover all this while. As a result, Kampei always felt guilty and responsible for his master’

The British invasion Essay Example | Topics and Well Written Essays - 750 words

The British invasion - Essay Example According to Curtis (1987), rock music is a common name of many musical styles that emerged in the mid 50s. Rock is not just music; rock became a global cultural phenomenon and formed the basis of many subcultures. The origins of rock music are blues, but rather, in rhythm and blues - a synthetic genre of popular music, primarily African-American musicians performed elements of jazz, blues and gospel in it. In continuation it is necessary to add that American rock and roll is the earliest genre of rock music, which combined the features of blues, rhythm and blues, jazz, boogie-woogie and country music in it. Naturally, America, being a home to all of these genres, was the most successful in promoting rock and roll, and the most famous ‘pioneers’ of rock and roll came from the United States too. The United States occupied a dominant position in rock music until the early 60s, when in England began to appear the bands playing a new style of dance music – bits under the influence of folk music. Then appeared merseybeat style of music, which was among the bits subgenres and was presented by Gerry & The Pacemakers, The Searchers, Rory Storm and the Hurricanes, as well as early The Beatles recordings were made in this style. It was The Beatles who were able to press American artists in the charts with their single â€Å"I Want To Hold Your Hand†, and begun the British invasion. Observing the British invasion it becomes obvious that the British rock groups, famous rhythm-and-blues teams, began a rapid rise in their activities. Their hits were as popular as it was possible and even in American charts they have occupied leading places; the glory of the British rock groups flew in a few seconds all over the world. Records and tapes were swept from the shelves as fast as possible, they were overwritten by fans, and resell for big money. In general, it was a real feast of Rock. Musical groups included in the wave of the British invasion were divi ded into different areas of rock music. The most successful with a more melodic and soft merseybeat were Herman's Hermits, Manfred Mann, The Hollies, The Searchers, while easy beat with elements of folk music was played by The Zombies. Analyzing the British invasion, Curtis (1987) stated that â€Å"though not all of the bands sounded similar -- they ranged from the hard rock of the Rolling Stones and the Kinks to the sweet pop of Gerry & the Pacemakers and Herman's Hermits - each group was heavily influenced by American rock & roll, blues, and R&B.† Many groups have been actively influenced by rhythm and blues, for example, The Yardbirds, as well as The Animals, famous for the use of organ music. According to Friedlander (1996), exactly legendary The Rolling Stones achieved the greatest success and undeniable popularity. Their image was much more aggressive in comparison with the performers of merseybeat, and songs, such as the famous â€Å"(I Can't Get No) Satisfaction†, sounded much heavier. The Rolling Stones were perceived by the American public as more "acute" and even a dangerous group. They positioned their music, as closer to the traditional "black" rhythm and blues. They created a specific image which separated them from the environment of beat artists such as The Beatles, who were harmless pop band on their background, more acceptable by the

Com 263 Assignment # 2 - Essay Example The dinner table is considered a formal type of gathering and is considered an important event. This reflects the Hispanic culture that places a high value on family. Because mealtime is considered to be an important and formal event, formal communication skills are stressed. The children, aged 6 and 9, are instructed to speak clearly and in complete sentences. Children are also taught that there is an appropriate time to speak and an appropriate time to listen. Slang is not encouraged and though the family speaks Spanish, they use English at the table. This is a non-verbal message that reflects the value they place on America. Other non-verbal messages, such as hand gestures and facial expressions, are not allowed in the formal setting. These non-verbal messages are prized by the culture in informal communication, but children are discouraged from using them with elders or in formal settings. One of the basic cultural norms for the Hispanic family is that children must listen to their parents. This conveys a high degree of respect for age and authority. The children are also taught to listen attentively to anyone that is speaking and attempt to understand what is being said. Though the children are bilingual, English is their first language. In less formal settings the children are taught Spanish and encouraged to speak and understand both languages. They are also taught to ask questions about any conversation they dont understand. They are instructed to react in a proper manner and not engage in sibling rivalry or mocking at the dinner table. One of the basic understandings of this cultural setting is that the father is the head of the table and will control the meal as well as the communication.

One Way Analysis of Variance Essay Example for Free

One Way Analysis of Variance Essay One-way Analysis of Variance (Abbreviated one-way ANOVA) is a technique used to compare means of two or more samples (using the F distribution). This technique can be used only for numerical data. It consists of a single factor with several levels and multiple observations at each level. With this kind of layout we can calculate the mean of the observations within each level of our factor. The residuals will tell about the variation within each level. It can also average the means of each level to obtain a grand mean. And then look at the deviation of the mean of each level from the grand mean to understand something about the level effects. Finally, can compare the variation within levels to the variation across levels. Hence the name analysis of variance. Used to determine whether there are any significant differences between the means of three or more independent (unrelated) groups. It tests the null hypothesis that samples in two or more groups are drawn from populations with the same mean values. And compares the means between the groups you are interested in and determines whether any of those means are significantly different from each other.

Wcf Architecture In Depth Information Technology Essay

Wcf Architecture In Depth Information Technology Essay Nowadays distributed system becomes increasingly significant and a great number of developers utilize that technology to build their applications. One of the most common used technologies is WCF which stands for windows communication foundation. WCF is utilized on windows platform and .NET framework. On .NET framework WCF is the first service-oriented model. There are three important components in WCF in terms of programming model and they are address, binding and contract. Moreover, there are two layers in layer structure of WCF and they are Messaging layer and Service Model layer. In order to understand WCF deeply some good features of WCF will be introduced such as unification of different technologies, interoperability with other existing applications and fully support for Service-Oriented development. Key words: WCF, service-oriented development, architecture, layers WCF, unification and interoperability. INTRODUCTION WCF, which stands for Windows Communication Foundation, is utilized by many distributed system application developers for its outstanding advantages. WCF enables developers to build their applications which can meet different requirements by unifying current distributed technologies. Applications developed by utilizing WCF can interact with other applications developed in other languages and on other platforms easily. Updating conveniently is another advantage WCF has, since it is unnecessary to re-deploy the whole application if only a part of the solution needs to be modified. Address, binding and contract are the three essential components of WCF. Address is used to guide the packets to the destination. Bindings responsibility is to specify the methods how the packets are sent. Contract is in charge of what message the packets should have. The layer structure of WCF will be introduced in this research as well. Messaging layer and service model layer are the two layers. WCF has som e outstanding features and these features will be illustrated in the following paper. SERVICE-ORIENTED ARCHITECTURE WCF utilizes service-oriented as its model, as a consequence, it is necessary to introduce the service-oriented architecture (SOA) before introducing WCF. Comparing to object-oriented architecture, SOA can solve many problems which are brought up by object-oriented architecture. For example, different components of an application do not depend on each other tightly, so modifying applications so as to meet the business needs is not expensive and complicated any more. Some of the significant features and principles will be illustrated as follows. The definition of SOA is that SOA contains a set of services and these services were designed well by other developers. Hence, different services have a loosely-coupled relationship which enables developer to modify any services as needed without affecting any other services. More specifically, in object-oriented model changing only a small part of the solution will lead the whole application to be redeployed. However, in SOA all the services do not depend on each other tightly and they are all autonomous. The client side of an application has no clue about the implementation process on the sever side and vice versa, as a consequence, implementing and modifying services on both client and server is flexible. If a service needs to be updated and the service is still available there is no need to modify services on the client side. Schemas and contracts, which are two significant component of SOA, are two aspects that SOA concentrates on to communicate with different nodes rather than classes. As a consequence, SOA enables the distributed application platform and language independent. ARCHITECTURE OF WCF WCF has attracted more and more attentions due to many pros of it. Before WCF was invented, what developers utilized to develop applications were DCOM, .NET Remoting or Web service. However, these technologies brought many drawbacks including security, cross-platform and performance and so on. After WCF was invented a great number of developers had started to utilize the new technology and the problems mentioned above can be solved by WCF completely. In order to understand deeply about WCF, the architecture of WCF will be illustrated as follows. wcfabc.png Figure 1[5] Communication through the endpoint  ·The most important components of WCF are address, binding and contract. Address is responsible to inform the data packet where to go. Binding is in charge of the way how to communicate with the services. Contract is used to define what the service contains or what the service is able to do. These three components of WCF are also known as ABCs of WCF. Endpoint as shown in the figure 1 constitutes address, binding and contract and it is can be seen as the gateway for other clients. In order to communicate with a service, clients should know the ABCs of that service. As we know, the Web Service Description Language (WSDL) is responsible to describe what an endpoint can do and how to access that endpoint. C:UsersmalongDesktopWCF architecture.jpg Figure 2 [4] WCF Programming Model Figure 2 shows all the components of WCF programming model more details about this Model will be illustrated as follows. There are two sides of this programming model and they are client side and service side. Client side The client side can only consist of one endpoint which has address, binding and contract for each service. In the whole program the client side contains a proxy which enables the client to communicate with the service. When communicating with different services the client can utilize multiple proxies which use multiple endpoints accordingly. A proxy is utilized to fulfill the job of CLR interface which has the same the function as service contract. Proxy not only does the job of service contract but also provide extra functions to manage the life cycle of a proxy. All the attributes of a service are assembled by a proxy such as service address, service running environment and transport protocols. Different behaviors can be defined by the client in order to configure the local configuration files including instancing, concurrency, transaction control and security. Service side There can be multiple endpoints on the service side and these endpoints are in charge of sending messages to a service if there are some services requesting message sending in. behaviors do the same jobs as the behaviors do on the client side. On the service side there is a significant component named dispatcher which is related to the proxy in the client side. Proxy and dispatcher work together to convert between methods that clients desire to invoke and WCF messages. Channel dispatcher and endpoint dispatcher constitute one channel stack. Channel dispatcher is responsible for getting messages from the channel and choosing the endpoint dispatcher in which these messages will be dealt with. Endpoint dispatcher consists of filters and dispatch runtime. More specifically, it is the filters that make sure the incoming messages are dispatched to the right function within a service object. After the messages are dispatched to the endpoint dispatcher, the message will be transfer to dispatch-runtime within that endpoint dispatcher. The object of Dispatch-runtime is utilized to choose which function to call and serialize or de-serialize functions parameters and control objects lifetime. More details about ABCs of WCF Address Address is utilized to tell clients where the location of the service is. Of course, before a client can communicate with the service side, it needs to know the address of the service first. The format of the address in WCF is URLs. In the URLs, many things are defined including protocols, the address of the terminal providing services and the path which can enable the client to get access to the actual service. In URLs port number in address is not fixed and which port number to use depends on the types of transmitting protocols. More specifically, there are four parts of the address section. Firstly, transport scheme is responsible to define the protocol which is used to transfer message. Secondly, Name of the service machine is used to locate the machine which provides the services. Moreover, the name for that machine should be fully qualified domain name which can be translated to the right IP address by some DNS servers. Thirdly, what port number developers can use totally based on transmitting protocol. By default port 80 is for HTTP address. The last one is path which is the name of the directories. Here is the format of address Scheme ://< hostname of service > [: port number]/path1/path2. Binding Binding plays a vital role of defining the method to communicate with service side. Binding is responsible to control transport, channels, encoding and WS protocols. WCF has provided a large number of models of binding and these models can almost satisfy most of the developers. Custom binding can be built to meet the needs of developers who have special demands for the binding model. More specifically, a binding can be seen as a multiple layered stack which contains one or multiple channels and these channels are in charge of processing data. Transport channel is at the lowest level of this stack which is utilized to adapt the stack to the transporting protocols such as TCP, HTTP and SMTP. This special stack is used to supply with a concept. And that concept is responsible to define in which way the message should be sent and to define what the messages should contain or what protocols should to be used for transmission. Contract Contract is used to define what a message should contain or what services the service side can provide. More specifically, it is the contract that defines what services need to be exposed to outside thereby deciding what to implement inside. Moreover, contract enables the interoperation between different platforms to be authentic. Three different types of contract will be illustrated as follows. The first one is service contract which is utilized to define the transmitting methods among clients and services. Message contract is the second one and is used to define the message architecture. SOAP envelop can be modified by message contract. The last one is data contract which holds the information of classes such as types defined in classes and that information will be transferred between clients and service. There are three messaging transmission methods and they are one-way, request-replay and duplex. In the one-way pattern a client sends out messages to the service, but the client does not wait for the response of that service. The pattern is like invoking an asynchronous function which does not have a return value. The second pattern is request-reply pattern in which the client will wait for a response from service after sending a message. That client is able to do nothing until it receives the response from the service. In other words, the request-reply is a two way interoperation which can be seen as a synchronous communication. This request-reply pattern is utilized as the default method in WCF. The last one is duplex pattern and this pattern is the most complicated manner comparing to other two patterns. The duplex pattern is a real peer-to-peer communication and the client and the service send and receive messages simultaneously which are transferred on different channels. In thi s method the client and the service can be seen as the message initiator. THE LAYER STRUCTUR OF WCF Figure 3[4] The layer structure of WCF WCF has a layered structure which contains two different layers and they are service model layer and messaging layer. What a developer to do on the service model layer is to do the programming task, however, the messaging layer, which is underneath the service model layer, is responsible to transport the all the messages to the destination. The concept of layer structure enables to separate the programming from the messaging. As shown in the figure 3, service model layer is the top layer which is in charge of contract, policy and behavior. And behavior is the most significant part among these three. Channels, encoders, transports and protocols are the components of messaging model in which the channels is the most important part. Messaging layer In messaging layer all the real messages are transferred on this layer which is similar to the network layer and data-link layer in OSI model. Moreover, transports protocols are defined at this layer as well. Format for the messages and the messages encoding rules are both defined at messaging layer too. Channel is a function that the messaging layer provides which is responsible to transmit messages among clients and services. Channel function is so important that messaging layer is sometime called channel layer. Address and binding are two significant components in channel. Address is utilized to tell the message where the service location is and the bindings responsibility is to manage the methods that messages should be sent. In order to enable the messaging transmission to work well between clients and services, both the client and service need to understand all the variables such as protocols, the encoding, method defined to transfer message and transport. It is the factory tha t enables the client side to create channels so as to communicate with services. Listener plays the role of accepting messages from client side through predefined channels. Channels another function is that it can monitor the forwarding messages and receiving messages by utilizing specified transport and messaging transfer method. Service Model layer Service model layer enables to affect the messaging process by utilizing object-oriented programming rules. When developers design their applications the design actually happens at this layer. In other words the service model layer responsible for the design of the application and it provides user-friendly API which includes classes, functions, attributes and configurations. In service model layer the most significant part is behavior and client and service can have multiple behaviors. Behaviors do have effect on the translation from messages to .NET attributes rather than affecting on contract. UNDERSTAND WCF IN DEPTH Unification of current technologies Nowadays a number of distributed technologies are utilized by developers to develop their applications. Although there are some advantages of these technologies, these technologies brought many problems. These technologies utilize different programming languages and models. If developers desire to build distributed system they need to utilize distinct APIs. WCF is the new technology which enables developers to build distributed system for different business corporations by utilizing only one API. WCF can be seen as the combination of these current distributed technologies such ASMX, .Net Remoting, MSMQ and WS-* technology. WCF also inherits the advantages of these technologies such as efficiency from ASMX, extensibility and flexibility from .Net Remoting and so on. Some of the technologies will be illustrated as follows. ASMX stands for ASP.NET Web Services which provides great interoperability and the ability to make packets pass through firewall easily. ASMX transfers data through messages as well. Different transport protocols can be utilized to transfer message such as HTTP and TCP. And the main protocol for message is SOAP the format is XML. However, ASMX is not flexible in choosing delivery methods and security manners. It is the ASMX that enables to communicate to applications which is developed by J2EE across the internet. ASMX has been seen as a very outstanding vendor-independent technology. .NET Remoting has a good support for the lifetime management and self-defined hosts. Moreover, it has an outstanding extensibility and flexibility. If there are many boundary clients which needs to communicate with a central server .NET Remoting is the best choice, because the both the client and the server should be developed on .NET environment. This .NET to .NET architecture provides the best performance. Enterprise Services is the next generation of COM+ and can be utilized to manage the lifetime of object and specify the distributed transactions. Enterprise services enable developers to focus on building service-oriented components. The interoperability is one of the relatively serious drawbacks. And the number of communication protocols which support this technology is small. WSE stands for Web Services Enhancements and can be utilized to talk to J2EE based applications. A large number of the agreements which are defined in web services have been implemented in WSE, as a consequence, WSE can be called WS-* specifications. WSE can ensure the security of an application. MSMQ is the abbreviation of Microsoft Message Queuing. MSMQ enables to send messages to the partner applications which are not available or online. In other words, MSMQ lets the messages stayed in the queue and sends the messages to the server when it is available. MSMQ is the best for applications that the servers are not online all the time. C:UsersmalongDesktop1.jpg Figure 4[1] Unification feature of WCF Figure 4 shows the summary information about the technologies that WCF has unified. As we can see from figure 4, WCF provides more for developers, which enables to build applications much conveniently and efficiently. How to unify different technologies WCF enables developers to use all the good points from other technologies straight away. In order to make the other technologies work for WCF, developers need to attach specified elements to the contract of WCF. WCF can gain a great number of good features due to the unification of others technologies. Some of the good features which inherited from Web Service are shown as follows. Because WCF has a good support for web service, WCF gains some good features about security. WS-security and WS-Trust enable WCF to provide many functions including integrity checking, authentication and so on. These features can ensure the security for the transmission for SOAP messages. WS-Reliable messaging adds an additional tag into SOAP header which enables WCF to ensure its communication much reliable. WCF also supports the integrity of the data because of the feature of WS-Coordination and WS-Atomic. WS-Addressing can be used to make the messages transmission without utilizing transport protocols. Interoperability with Other Platforms Nowadays distributed applications are developed in many different languages and the technologies utilized are invented by many different vendors as well. That situation happens in many enterprises and the applications using WCF can communicate with other applications using other language or software because WCF utilizes SOAP as its communication protocol. WCF based applications are able to interact with applications working in distinct process on same terminal and applications working on other terminals. Applications built on WCF can interoperate with each other when they are run on different operating systems such as Linux and windows. WCF is able to enables the previous technologies to with compatibly with itself. More specifically, SOAP is utilized by both ASMX and WCF; as a consequence, ASMX built-on applications can work compatibly with applications which are based on WCF. Service-Oriented Development is supported Over the next few years, creating applications in a service-oriented style will become the norm. For this to happen, the platforms on which those applications are built must provide the right support for creating service-oriented software. Achieving this is one of WCFs most important goals. Building distributed applications by using Services-oriented Development will be increasingly popular. WCF is seen as the first service-oriented development technology in the platform of windows, which provides a good support for platform independent and updating services conveniently. What does WCF concentrate on is the service rather than object. Some of the key principles about WCF are illustrated as follows. The first one is shared schema. Communication between applications never depends on classes anymore and what they depends on is schema which has be predefined in both of these applications. The behavior transferring attributes such as classes or functions will be banned. Secondly, services are all independent. An interface should be defined between clients and services, which enables the application language and platform independent. However, the clients and services should be loosely-dependent. Lastly, the boundaries should be defined clearly. The explicit boundary enables the remote objects to be seen as they are local. CONCLUSION In conclusion, WCF is a Windows platform service-oriented technology which is able to provide interoperability between different applications. Nowadays distributed application developers prefer to utilize technologies built on service-oriented architecture. One of the advantages of service-oriented architecture is that different components of an application depend on each other loosely, so modifying application in order to meet the business needs is economical and easy. WCF is an outstanding representative of SOA and it has three significant components in its programming model. The three components are address, binding and contract. Address is used to tell where the message should be transferred. Binding is responsible to define how to communicate to a service. Contract is in charge of describing what services are provided. There are two layers and they are service model layer and messaging layer in terms of WCF layer architecture. One of the important responsibility in messaging lay er is how the real messages can be sent out with all the attributed being serialized. Service model layer is responsible for the design of the application and it provides user-friendly APIs for the future utilization. In order to get a deep understanding WCF, a number of features of WCF was introduced. WCF is like a combination of other distributed technologies and it makes the combination of technologies is much user-friendly. Shared schema, Independent Services and Clearly Defined Boundaries are the three key principles to SOA.
