THE SOURCES OF PUBLIC POLICY: WELFARE POLICY IN THE AMERICAN STATES

The conceptualization of political and economic determinants of public policy as interactive rather than sufficient causes is subjected here to a comparative state analysis. An examination of interactive effects of culture, wealth, and gubernatorial power on AFDC grants and Medicaid benefits offers empirical illustration of Stonecash's reconceptualization of the classic politics-process-policy model. The results indicate that political dispositions become more potent in combination with increasing concentrations of wealth and executive power.     

THE ECOSYSTEM HEALTH METAPHOR IN SCIENCE AND POLICY

Ecosystem health' is an increasingly common metaphor in the langauge of science and policy. Given the prominence of both the ecosystem and health concepts within geography, this paper examines the meanings generated by the adoption of the metaphor for scientific research and for environmental policy on the North American Great Lakes. 'Ecosystem' can be characterized as an entity, an abstract concept, or a perspective. As perspective, ecosystem shares many features of postmodern science, emphasizing complexity and holism and calling for the inclusion of human beings in our considerations of nature. The ecosystem health metaphor is politically powerful in its ability to evoke action and concern for the environment with an appeal to the universal experiences of human ill-health. The organismic ecosystem health metaphor provides a new, relevant way of thinking about the natural world. In policy discourse, however, metaphor can be problematic in that there is potential for the author or speaker to hide behind the nonliteral language. Moreover, the acceptance of the ecosystem health metaphor which can draw upon widely held beliefs and norms implies that other ways of knowing the world are necessarily omitted. We highlight some of these issues in a case study of a policy document prepared by the Ecological Committee of the Great Lakes International Joint Commission. To continue to know how to study nature in new ways, metaphors must be encouraged, but their meanings must also be widely explored     

SOCIAL SCIENCE AND SOCIAL POLICY: ROLES OF THE APPLIED RESEARCHER*

Research on policy impact has increasingly focused on the practical application of social science research. This paper outlines four roles—substantive expert, information processor, change agent, and scholar—which have helped to increase the potential usefulness of our research while maintaining linkages to the academic community. This paper suggests the general nature of these roles and suggests specific implementation strategies, which need to be pursued as an early and continuing aspect of the research enterprise. Balancing these multiple roles presents several analytical and ethical difficulties, but helps to establish credibility in both the scientific and policymaking communities.     

PARADIGMS IN THE STUDY OF HEALTH POLICY

This essay identifies and analyzes four different paradigms in the study of problems in the American health system. The paradigms, which are labelled the individual–deficiency, the economic, the organizational, and the Marxist perspective, are examined as “diagnostic paradigms” according to the way in which problems are conceptualized and the way in which remedial strategies are chosen. The essay shows the differences and similarities between characteristic diagnoses and policy solutions within the four perspectives. It is argued that such paradigms can easily be identified in recent health reform proposals.     

THE EFFECTS OF REGIONAL SCIENCE AND TECHNOLOGY POLICY ON THE GEOGRAPHIC DISTRIBUTION OF INDUSTRIAL R&D LABORATORIES*

ABSTRACT. The determinants of the geographic distribution of industry R&D activity are examined with particular emphasis on the role of university research as well as state science and technology programs. An analysis of a cross section of metropolitan areas indicates that industry R&D labs are located in areas with state science and technology programs, as well as in areas with higher levels of university research, larger quantities of non-welfare related local government spending, a better educated workforce, and a greater population density.     

THE MISSING NARRATIVIST TURN IN THE HISTORIOGRAPHY OF SCIENCE

The narrativist turn of the 1970s and 1980s transformed the discussion of general history. With the rejection of Rankean historical realism, the focus shifted to the historian as a narrator and on narratives as literary products. Oddly, the historiography of science took a turn in the opposite direction at the same time. The social turn in the historiography of science emphasized studying science as a material and practical activity with traceable and documentable traits. This empirization of the field has led to an understanding that history of science could be directly describable from scientific practice alone without acknowledging the role of the historian as a constructor of narratives about these practices. Contemporary historians of science tend to be critical of science's ability to describe its object—nature, as it is—but they often are not similarly skeptical of their own abilities to describe their object: past science, as it is. I will argue that historiography of science can only gain from a belated narrativist turn.     

论清代中期清政府对外国货币的政策

16世纪末-17世纪初,随着东西方新航路开辟,外国商人较频繁地来到中国贸易。明清之际,外国商人来华购买中国商品,偶用外国货币支付。清康熙时,“时华洋互市,以货易（洋）银”,乾隆时“洋钱盛行”,到道光时期,外国货币“行用日广,公私出人,非此不济”①,似有垄断市
