Historically, the British environmental movement has been devoid of minority participation, but this is changing very slowly, with the emergence of ethnic minority environmental groups and multiracial environmental alliances. These groups have argued that ethnic minorities have little or no access to public funds earmarked for countryside and wildlife preservation issues. They argue that white environmental organizations do not pay attention to the needs of inner-city minority residents and minority access to the countryside. Increased access, community improvement and beautification projects, environmental education, youth training, community garden projects, and issues of environmental racism are all foci of ethnic minority environmental movements. While some white environmentalists have been supportive of them, others have been uncomfortable with them or even hostile to their existence. 相似文献

Wald and Wolfowitz (1948) have shown that the Sequential Probability Ratio Test (SPRT) for deciding between two simple hypotheses is, under very restrictive conditions, optimal in three attractive senses. First, it can be a Bayes-optimal rule. Second, of all level α tests having the same power, the test with the smallest joint-expected number of observations is the SPRT, where this expectation is taken jointly with respect to both data and prior over the two hypotheses. Third, the level α test needing the fewest conditional-expected number of observat ions is the SPRT, where this expectation is now taken with respect to the data conditional on either hypothesis being true. Principal among the strong restrictions is that sampling can proceed only in a one-at-a-time manner. In this paper, we relax some of the conditions and show that there are sequential procedures that strictly dominate the SPRT in all three senses. We conclude that the third type of optimality occurs rarely and that decision-makers are better served by looking for sequential procedures that possess the first two types of optimality. By relaxing the one-at-a-time sampling restriction, we obtain optimal (in the first two senses) variable-s ample-size- sequential probability ratio tests. 相似文献

Parents of children in public schools in a large American urban center, representing a number of different ethnic groups, were interviewed about their personal views and feelings toward cultural and racial diversity in America today. Three main issues were addressed: respondents' attitudes toward the maintenance of heritage cultures versus assimilation; their attitudes toward bilingualism; and their attitudes toward other groups in the community. The analyses revealed important differences in attitudes between ethnic minority groups and established white and black groups. Nonetheless, strong support was shown for the retention of heritage cultures, even among middle-class white and working-class black Americans. The working-class white American sample was distinctive in its rejection of multiculturalism and in its negative attitudes toward other ethnic and racial groups. All groups supported the idea of bilingualism for their children, and certain groups thought that public schools had an important role to play in its promotion. Overall, the results delineate a series of factors that affect intragroup and intergroup harmony and the processes of adjustment that transpire within a social system when it has to cope with ethnic and racial diversity. 相似文献

A distinction between Fisher's implied data-generating process for Monte Carlo cycles and the more general Markov process leads to non-parametric tests for duration dependence. Tests are based on the method of moments, Tauchen's generalized method of moments (GMM) procedure, and a statistic whose null distribution probability limit is zero. Using finite-sample critical values obtained by Monte Carlo methods, our test results are remarkably consistent. The null distribution of the GMM test statistic for samples of the size considered is distinctly non-normal, so that asymptotic critical values give erroneous results. The tests are applied to UK business cycle data for 1854-1992. There is evidence for duration dependence in expansions but not in contractions. 相似文献

The UK has, over recent years, moved from a welfare state to a more market-oriented system of welfare. But the extent of this change has varied considerably according to the ideological position of local government in different parts of the country. This makes it possible within one country to assess the implications for the voluntary sector of different models of welfare. This article develops a framework for looking at different welfare ideologies and the values they espouse, with reference both to the UK and to the models that exist in other countries. It then takes four examples of UK local authorities which demonstrate the different models and examines the implications for the voluntary sector. In doing so, it examines the prospects for the voluntary sector to deliver both service and political pluralism in the future. 相似文献

In the field or purchasing and supply, 1973 was a year to be remembered. A world-wide boom in industrialised countries produced record prices in markets for food, raw materials and manufactured goods. Rates of inflation in the U.S.A., Western Europe and Japan began to approach South American levels. The value of the dollar, the pound and other major currencies fluctuated dramatically, and the stock market experienced falls comparable to those which occurred during the slump in the thirties. Finally, 1973 was the year of the oil embargo, when oil prices were almost doubled and oil supplies to the West were cut by 15–20%, resulting in the rationing of oil and other commodities in Western Europe.By any standards, this was a momentous year. It is conceivable that supply markets will never be quite the same again. The traditional form of multi-national business, integrated from supply to consumer markets, is fast disappearing as the companies formed in developing countries to secure the supply of oil, food and raw materials are being taken over by the host governments. Indeed it may be that after the traumatic experiences of this year, negotiations for food and key raw materials will be increasingly carried out by governments rather than by private companies.To cope with shortages and higher prices in food, fuels and essential raw materials, government bodies and public and private enterprises will have to develop new capabilities. Western governments have responded quickly by setting up Ministers and Ministries for Energy and by establishing huge budgets for research into the exploration and exploitation of alternative fuels. The large oil companies have declared that they are in the “energy business” and have bought interests in nuclear power and coal.But what does the energy and resource crisis mean for the average firm? It seems that in the 1970s we are experiencing a level of competition for supplies similar to the competition for consumer markets which first produced “Marketing” in the late fifties and early sixties. 相似文献

Portfolios for learning and assessment: laying the foundations for continuing professional development 总被引:2,自引:0,他引:2
Portfolios are widely used in a range of education programmes at different levels in a number of countries. They are also well established at all stages in social work education. However, in the literature there is surprisingly little critical analysis of the application of the portfolio in social work. In this paper the authors' objective is to contribute to professional knowledge about the use of portfolios in social work. The authors are all members of the Higher Education Funding Council Self-Assessment in Professional and Higher Education Project and are concerned to develop self-assessment in social work and enhance the development of life-long learning. They begin by examining the literature about portfolios from the field of education. Findings are then analysed from a small exploratory study of the use of portfolios in practice learning on a Diploma in Social Work course. Five different but related conceptual themes which emerge from the analysis are discussed: compiling the portfolio; issues of evidence; reflection in a context of assessment; the practice teacher and the learning dialogue; and the challenge of assessment. Suggestions are offered for effective portfolio practice. 相似文献

Abstract While increasing enrolments of international fee-paying students are a feature of the current Australian tertiary system, little research has been undertaken relating to international students studying social work. A national survey of all accredited BSW programs within Australia was undertaken in 1997 with regard to the demographic profile of international students, current provisions for them and perceptions of educators about relevant issues for consideration. The findings of this survey are presented here. Fee-paying international students represented a small proportion of total enrolments within Australian BSW programs in 1997. While educators perceived that these students did have particular educational and social challenges within Australian social work programs, few special considerations were afforded to them, although the literature would encourage us to consider this. Issues relating to the social and cultural construction of Western social work education are discussed, as well as the cultural relevance of Australian social work education for international students intending to practise social work in their countries of origin. 相似文献

Social workers attempting to bring about social change are encouraged to select and develop practice models that reflect their own theoretical and personal stance. The use of the small group process is seen as one avenue worth exploring in any attempt to achieve effective social change. 相似文献

Two methods of bootstrap, viz., standard, and conditional, are presented for estimating the transition probabilities of a finite state Markov chain. Asymptotic validity of the bootstrap estimates are established for both methods. An applica- tion to a bootstrapped statistic for testing independence is briefly discussed together with some simulation results. 相似文献
