This article offers some critical realist, strategic‐relational comments on Colin Hay's proposal to treat the state as an ‘as‐if‐real’ concept. The critique first develops an alternative account of ontology, which is more suited to analyses of the state and state power; it then distinguishes the ‘intransitive’ properties of the real world as an object of investigation from the ‘transitive’ features of its scientific investigation and thereby provides a clearer understanding of what is at stake in ‘as‐if‐realism’; and it ends with the suggestion that a concern with the modalities of state power rather than with the state per se offers a more fruitful approach to the genuine issues raised in Hay's article and in his earlier strategic‐relational contributions to political analysis.  相似文献

A self-completion questionnaire containing items about recent gambling and problem gambling used in the British Gambling Prevalence Survey (BGPS) was completed by 274 clients of alcohol and drug problems services in the English West Midlands. Compared to BGPS data, matched to the client sample for age and sex, clients were significantly more likely in the previous 12 months to have engaged in forms of gambling carrying a high risk of problems, to have engaged in four or more separate forms of gambling, and to have scores on a brief form of the South Oaks Gambling Screen (SOGS) indicating problem gambling. A self-completion scale on attitudes towards working with problem gamblers, with good psychometric properties according to present data, was completed by 91 members of staff of the same services. With the exception of a sub-scale measuring perceived adequacy of knowledge and skills for working with problem gamblers, staff expressed moderately positive attitudes. It is concluded that British substance misuse services are appropriate locations for the development of services for problem gambling.  相似文献

Since the early 1990s, North Carolina has been the fastest growing swine-producing state in the country and the leading innovator in vertically integrated, industrially structured hog farming. Although the growth and concentration of swine production has been associated with a host of negative social and environmental impacts on the states air, land, and waterways, environmental justice and farm loss concerns have played a particularly key role in the evolution of the controversy in North Carolina. Using multivariate analysis of statewide census and agricultural data, we identified the county-level sociodemographic characteristics associated with farm loss between 1982 and 1997. We found that recent patterns of farm loss were more pronounced in Black communities, regardless of income, and low-income communities, regardless of race. Furthermore, counties that had greater hog industry growth in the early 1980s and had large hog populations by 1992 have suffered greater farm loss since the early 1980s than counties where the hog industry growth did not intensify until more recently. The implications of these findings with reference to an expanded environmental justice framework regarding the discriminatory impacts of swine facilities on minority and low-income rural communities are discussed.  相似文献

The most pertinent question concerning teaching and learning in the twenty-first century is not what knowledge and skills students need--that laundry list was identified over a decade ago--but rather how to foster twenty-first century learning. What curricula, experiences, assessments, environments, and technology best support twenty-first century learning? New Technology High School (NTHS) in Napa, California, is one example of a successful twenty-first century school. In this chapter, the author describes the components of this exemplary high school, illustrating an environment that will cultivate twenty-first century student learning. New Technology High School began by defining eight learning outcomes, aligned with the standards of the Partnership for 21st Century Skills; to graduate, students demonstrate mastery of these outcomes through an online portfolio. To help students achieve the outcomes, NTHS employs project- and problem-based learning. Whereas in traditional classrooms students work alone on short-term assignments that do not lend themselves to deep understanding, the project-based learning approach has students working in teams on long-term, in-depth, rigorous projects. Students' work is supported by the school's workplace-like environment and effectiv use of technology. Meaningful assessment is essential to project-based learning; students receive continuous feedback, helping them become self-directed learners. In fact, NTHS uses outcome-based grading through which students constantly know how they are performing on the twenty-first century outcomes. Research has shown that NTHS graduates are better prepared for postsecondary education, careers, and citizenship than their peers from other schools. To facilitate twenty-first century learning, all schools need to rethink their approach to teaching and learning. New Technology High School is one way to do so.  相似文献

This paper argues that the managerialist influence on the DipSW has meant that both the models of social work and of social work education that have come to dominance since it was first approved in 1989 are incompatible with the development of anti-racist practice. We explore the potential of reformulating social work as a communicative activity and the implications of this for the education of social workers. We argue that this would require an approach that incorporates three main elements: an analysis of the way in which power and disadvantage is distributed between racial groups and the ways in which this affects their ability to represent their own needs in political debate; an understanding of the ways in which the wider discourses of racial domination find expression in culture; and the development of our understanding of how intrapsychic representations of race and power come to be inscribed in mental life. It is through the interrelationship of these domains that anti-racist practice can become integral to social work.  相似文献

In earlier work we assembled a database of classical pharmacokinetic parameters (e.g., elimination half-lives; volumes of distribution) in children and adults. These data were then analyzed to define mean differences between adults and children of various age groups. In this article, we first analyze the variability in half-life observations where individual data exist. The major findings are as follows. The age groups defined in the earlier analysis of arithmetic mean data (0-1 week premature; 0-1 week full term; 1 week to 2 months; 2-6 months; 6 months to 2 years; 2-12 years; and 12-18 years) are reasonable for depicting child/adult pharmacokinetic differences, but data for some of the earliest age groups are highly variable. The fraction of individual children's half-lives observed to exceed the adult mean half-life by more than the 3.2-fold uncertainty factor commonly attributed to interindividual pharmacokinetic variability is 27% (16/59) for the 0-1 week age group, and 19% (5/26) in the 1 week to 2 month age group, compared to 0/87 for all the other age groups combined between 2 months and 18 years. Children within specific age groups appear to differ from adults with respect to the amount of variability and the form of the distribution of half-lives across the population. The data indicate departure from simple unimodal distributions, particularly in the 1 week to 2 month age group, suggesting that key developmental steps affecting drug removal tend to occur in that period. Finally, in preparation for age-dependent physiologically-based pharmacokinetic modeling, nationally representative NHANES III data are analyzed for distributions of body size and fat content. The data from about age 3 to age 10 reveal important departures from simple unimodal distributional forms-in the direction suggesting a subpopulation of children that are markedly heavier than those in the major mode. For risk assessment modeling, this means that analysts will need to consider "mixed" distributions (e.g., two or more normal or log-normal modes) in which the proportions of children falling within the major versus highweight/fat modes in the mixture changes as a function of age. Biologically, the most natural interpretation of this is that these subpopulations represent children who have or have not yet received particular signals for change in growth pattern. These apparently distinct subpopulations would be expected to exhibit different disposition of xenobiotics, particularly those that are highly lipophilic and poorly metabolized.  相似文献
