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.  相似文献

It is argued that variation in uncertainty about social program goals and causal processes should influence the selection of evaluation designs and methods. Eighteen prominent evaluation reports are examined to contrast predicted evaluation strategies derived from theory about organizational uncertainty with the actual evaluation methods used. It was found that the actual design, measurement, and analysis procedures were frequently different from procedures that were compatible with the kinds of program uncertainty described in the evaluation reports. It is suggested that theory and practice in program evaluation can be improved by systematically incorporating organizational concepts that would contribute to the selection of evaluation methods.  相似文献

Excavations at Muweilah have uncovered twelve buildings encircled by two pairs of walls and ditches. We have published preliminary studies of several buildings. Research has now progressed to a stage where it is possible to produce a more complete analysis of the architecture. In this report, we present a detailed discussion of the fortifications and each building with its installations. Our assessment of the architecture identified the repeated combination of three rooms in many of the buildings in the Central Area of Muweilah. Moreover, a detailed study of the fortifications revealed several means of accessing Building II, the columned hall, in the Western Area. These findings offer insights into the organisation of Iron Age II settlements in south‐eastern Arabia.  相似文献

This essay examines the transnational activities of National Socialist experts, focusing on the endeavours of the burgomaster of Stuttgart, Karl Strölin. In 1938, Strölin became president of the International Federation for Housing and Town Planning (IFHTP), one of the most distinguished international expert institutions for European and North American urban planning. The article discusses his belief that promoting an international convention on the protection of urban populations would contribute to German diplomacy in the initial period of the Second World War. Then it investigates the IFHTP president’s efforts to transform his institution into an outlet for National Socialist ideas against the background of the German advance through Europe. A final section deals with Strölin’s attempts to transform the IFHTP into a forum for evaluating urban reconstruction policies in the last year of the war. This biographical study shows how it was possible to juggle the logics and expectations of seemingly contradictory spatial and political realms during and after World War II. National socialist politics and ideology exacerbated the tensions between local, national and international affiliations, but at the same time never fully permeated the mechanisms of expert internationalism. By revealing how Strölin navigated between local ambitions, the demands of domestic foreign policy and the ethics of expert internationalism in three markedly different projects, this essay contributes to a growing body of scholarship on the cross-border activities of National Socialist professionals in (occupied) Europe.  相似文献
