Golnar A. Simpson Jay C. Williams Anne Brantley Segall 《Clinical Social Work Journal》2007,35(1):3-14
In response to a growing diversity of opinion regarding educational models and essential content in clinical social work education,
this paper offers a perspective concerning graduate clinical curricula. Part I, the foundational piece of the paper, discusses
the definition of clinical social work, social work’s core orientation and values, and influential contextual issues. The
interrelated core orientations guiding knowledge and skill development are identified as the person-in-situation perspective and the concept of relationship. Based on this foundation, Part II identifies elements of a contemporary biopsychosocial knowledge base and essential clinical
skills. This paper is intended to stimulate dialogue about a topic of importance to the profession and the clients it serves. 相似文献

SenGupta (1987) proposed a locally most powerful test which is globally (one sided) unbiased, and an estimator of p, the equicorrelation coefficient of a standard symmetric multivariate normal (SSMN) distribution. Here we use the idea in Williams (1984) to illustrate the construction and use of ancillary statistics to make inference about p. The test and confidence intervals based on this construction are conditionally optimal. 相似文献

A Discussion of Findings and Their Possible Implications from a Workshop on Bioterrorism Threat Assessment and Risk Management 总被引:1,自引:0,他引:1
In November 2001, the Monterey Institute of International Studies convened a workshop on bioterrorism threat assessment and risk management. Risk assessment practitioners from various disciplines, but without specialized knowledge of terrorism, were brought together with security and intelligence threat analysts to stimulate an exchange that could be useful to both communities. This article, prepared by a subset of the participants, comments on the workshop's findings and their implications and makes three recommendations, two short term (use of threat assessment methodologies and vulnerability analysis) and one long term (application of quantitative risk assessment and modeling), regarding the practical application of risk assessment methods to bioterrorism issues. 相似文献

After defining the complementary relation R of a binary relation R on a set X, this paper constructs the binary relation C (is a complementary property of) on the set P of nine well known elementary properties that R might possess. It deduces some theorems about C; especially that symmetry is the only one of these possible properties of R on X that is possessed by C on P. The set P may be enlarged to contain other elementary properties of R on X without changing the truth of these theorems, when the symbols of sets are properly modified. Finally, the paper discusses the desirability of a general theory of elementary properties of binary relations for the further development of statistical decision theory. 相似文献

Risk and its Management in Post-Financial Crisis Hong Kong 总被引:1,自引:0,他引:1
Raymond K. H. Chan 《Social Policy & Administration》2006,40(2):215-229
In the 1970s and up until the financial crisis occurred in the late 1990s, Hong Kong prospered in a relatively stable social, economic and political context. Since the financial crisis, however, its population has been increasingly exposed to risk: there has been job uncertainty and decreasing capacity for self‐reliance, leading to a growing reliance on public welfare and on families at a time when both are under pressure. The old welfare policies, unable to cope with the new risks, have been replaced by neo‐liberal reforms, redistributing the roles and responsibilities of the individual and the state, with a greater burden falling on the former. Individuals are required to be prudent to manage risk. While these reforms have relieved some of the burden on the state, both new social risk groups and ‘net taxpayers’ considered themselves to have borne disproportional costs. Society is facing serious problems resulting from ineffective old welfare policies, new social risks due to new policies, and the political upheavals arising from increased social conflicts and weakened social cohesion and solidarity. A further complication is that there is no acceptable platform or agent to negotiate a compromise between the polarized groups. This article argues that reliance on publicly funded risk coping strategies or on neo‐liberal risk prevention and mitigation strategies is not a desirable and sustainable policy. A commonly accepted political platform is required to negotiate a compromise which emphasizes shared and balanced roles and responsibilities, and a well‐conceived combination of risk prevention, mitigation and coping strategies. 相似文献

Does Privatization Protect Natural Resources? Property Rights and Forests in Guatemala 总被引:1,自引:0,他引:1
Objectives . Property rights are central to debates about natural resource policy. Governments traditionally have been seen as the appropriate custodians of natural resources for their citizens. More recently, many argue the privatization of property rights will ensure that users have incentives to manage their resources well. Common property, to the extent it is discussed at all, is seen as leading to the tragedy of the commons. We evaluate these claims by assessing property rights and forest conditions in two private and three communal forests in Guatemala. Methods . Data on biological and social phenomena from five forests (151 plots) and their associated communities were collected using the International Forestry Resources and Institutions Research Program protocols. Ordinary least squares regression was used to analyze four models. We examined t -scores for differences in coefficients for the different models. Results . The models demonstrate that de jure property rights are not a powerful predictor of variations among the sampled forests. Conclusions . We argue that de facto institutions and their enforcement are much more important than de jure property rights to forest management. Communities holding a forest in common can, under certain circumstances, create institutions to manage their resources as successfully as—or more successfully than—private owners. 相似文献

Do management tasks differ by field of practice? 总被引:1,自引:0,他引:1
The authors examine the question: Do management tasks differ by field of practice? Many social work Master's programs are organized on the principle of specialization by field of practice for both micro- and macro-practice students. Secondary analysis of task data suggests that managers and supervisors with MSW degrees perform the same task regardless of the field of practice. The study suggests a need to examine assumptions of current MSW curriculum organization. 相似文献

This article describes an application of a method for assessing risks associated with the introduction of an organism into a new environment. The test organism was a binucleate Rhizoctonia fungal isolate that has potential for commercial development as a biological control agent for damping-off diseases in bedding plants. A test sample of host plant species was selected using the centrifugal phylogenetic host range principles, but with an emphasis on economic species. The effect of the fungus on the plant was measured for each species and expressed on a logarithmic scale. The effects on weights of shoots and roots per container were not normally distributed, nor were the effects on the number of plants standing (those which survived). Statements about the effect on the number standing and the shoot weight per container involved using the observed (empirical) distribution. This is illustrated with an example. Problems were encountered in defining the population of species at risk, and in deciding how this population should be formally sampled. The limitations of the method are discussed. 相似文献

Ethylene oxide is a gas produced in large quantities in the United States that is used primarily as a chemical intermediate in the production of ethylene glycol, propylene glycol, non-ionic surfactants, ethanolamines, glycol ethers, and other chemicals. It has been well established that ethylene oxide can induce cancer, genetic, reproductive and developmental, and acute health effects in animals. The U.S. Environmental Protection Agency is currently developing both a cancer potency factor and a reference concentration (RfC) for ethylene oxide. This study used the rich database on the reproductive and developmental effects of ethylene oxide to develop a probabilistic characterization of possible regulatory thresholds for ethylene oxide. This analysis was based on the standard regulatory approach for noncancer risk assessment, but involved several innovative elements, such as: (1) the use of advanced statistical methods to account for correlations in developmental outcomes among littermates and allow for simultaneous control of covariates (such as litter size); (2) the application of a probabilistic approach for characterizing the uncertainty in extrapolating the animal results to humans; and (3) the use of a quantitative approach to account for the variation in heterogeneity among the human population. This article presents several classes of results, including: (1) probabilistic characterizations of ED10s for two quantal reproductive outcomes-resorption and fetal death, (2) probabilistic characterizations of one developmental outcome-the dose expected to yield a 5% reduction in fetal (or pup) weight, (3) estimates of the RfCs that would result from using these values in the standard regulatory approach for noncancer risk assessment, and (4) a probabilistic characterization of the level of ethylene oxide exposure that would be expected to yield a 1/1,000 increase in the risk of reproductive or developmental outcomes in exposed human populations. 相似文献
