Ronald N. Kostoff 《The Journal of Technology Transfer》1997,22(3):3-8
Conversion of science to technology typically represents a transition across cultures, organizations, time scales, perspectives, personal motivations and philosophies. The purpose of this special issue is to address the specific problem of efficient and effective conversion of science to technology. This special issue will focus on the ideas, concepts and principles (for improving the science to technology conversion) that can be derived from past and present practices, and will complement recent special journal issues on Research Impact Assessment (Evaluation Review, February 1994) and Performance Measures for Government Sponsored Research (Scientometrics, July–August 1996). The theme that permeates this special issue is that efficient science to technology conversion is a contact sport. It is critical that interested parties (from each side of the science-technology barrier) develop early awareness of, and subsequent early involvement in, each other's culture, problems, and potential to maximize opportunities for removing impediments to successful transition. Awareness and involvement can be greatly enhanced through the use of the latest findings and tools resulting from advances in information science and technology. The various papers in this special issue present concepts and successful examples for enhancing mutual awareness and deepening the breadth and period of involvement that eventually result in transition obstacle removal. 相似文献

This paper describes the Graphical Modeling System, a computer-based process for generating roadmaps. The system offers the following advantages and capabilities: (1) Graphically portraying relationships between research and potential applications; (2) Helping accelerate science conversion by promoting champion interest in further research development; (3) Showing the node-link relationships of a project/capabilities/requirements network; (4) Treating nodes (projects/capabilities/requirements) as multi-valued (multi-attributed) quantities which are allowed to exist in many different research-requirement pathways simultaneously. This multiple perspectives capability provides a more accurate depiction of the multi-application nature of most research and technology, and the software enables the user to highlight just those specific node-link subnetworks of interest (the desired researchrequirement. pathways) without being overwhelmed by all possible node-links which constitute the larger network; (5) Promoting communications; (6) Identifying science and technology gaps; and (7) Identifying obstacles to rapid and low-cost technology development. 相似文献

Trends and Developments in Program Evaluation in General and Criminal Justice Programs in Particular
Frans L. Leeuw 《European Journal on Criminal Policy and Research》2005,11(3-4):233-258
The paper first describes general trends in evaluation in (mainly) western societies. Why is evaluation growing, what are the characteristics of this ‘growth industry’ and what developments are occurring outside western societies? Trends in the evaluation of criminal justice programs in the USA, the UK and the Netherlands are then discussed. Two important developments are therafter highlighted: experimental evaluations and theory-driven evaluations. Both approaches are discussed, and some pros and cons are listed. Finally, the paper outlines some challenges for future work in the evaluation of criminal justice programs, stressing the importance of combining good designs with both program and social science theories. 相似文献

This article critically evaluates the theoretical and empirical literature on contemporary prostitution. Most research focuses
exclusively on street prostitution and female workers, with much less attention devoted to indoor prostitution, male and transgender
workers, customers, and managers. Drawing on the sparse literature available on these underexamined topics, the article demonstrates
how further research will yield a more nuanced and multifaceted understanding of contemporary prostitution. 相似文献

Symptoms of vicarious trauma, coping strategies, and prevention suggestions were investigated with 105 judges. Participants completed a self‐report measure developed for this study. The majority of judges (63%) reported one or more symptoms that they identified as work‐related vicarious trauma experiences. Female judges reported more symptoms, as did judges with seven or more years of experience. In addition, female judges were more likely to report internalizing difficulties, while judges with more experience reported higher levels of externalizing/hostility symptoms. Coping and prevention strategies were multi‐domain (i.e., personal, professional, and societal) and underscored the need for greater awareness and support for judges. 相似文献
