Economic appraisals have often relied heavily on the factor use and factor price characteristics of process. In this article we treat impact of product characteristics in choice of technology. Product characteristics are specially important in the earlier stages of manufacturing, namely, commodity processing. The study elaborates also on circumstances which lead to the emergence of different and fluctuating relationships between product prices in different countries, respectively, developing and developed, and their implication for the choice of technology in these countries. 相似文献

How do different policy environments influence the choice of policy entrepreneurship (PE) strategies? Using data collected from a systematic review of the PE literature, the authors identify subcomponents of the three streams of the policy process and empirically test the relationship between dominance of each stream and PE strategies. Findings show that when the political and policy streams dominate, policy entrepreneurs focus on policy formation and policy implementation strategies and not on problem identification and policy evaluation strategies. Surprisingly, there is no correlation between dominance of the problem stream and PE strategies. This should lead to the normative claim that PE is not necessarily a positive phenomenon. The article concludes with suggestions for future research. 相似文献

Research evaluation is increasingly influenced by quantitative data. We focus on the influential Web of Science Journal Citation Reports (JCR) ranking of law journals and critically assess its methodology. In particular, we consider the existence and impact of a tacit citation cartel between US law reviews. A study of 45 US student‐edited (SE) and 45 peer‐reviewed (PR) journals included in the category of Law in the JCR revealed that PR and SE journals are more inclined to cite members of their own class and that this phenomenon is more pronounced in SE generalist journals, reflecting tacit cartelistic behavior generated by deeply entrenched institutional practices. Because US SE journals produce more citations than PR journals, the fact that their citations are directed almost exclusively to SE journals elevates their scores and distorts the journals' ranking and can consequently undermine the flow and creation of ideas. We discuss policy measures that can counter the adverse effects of this situation. 相似文献

This study tested the hypothesis that investments in early childhood schools have short-term crime reducing effects in neighborhoods. Time series data from the city of Tulsa, Oklahoma, were analyzed to evaluate the effects of an early childhood school built in the neighborhood of Kendall-Whittier as part of a larger neighborhood revitalization plan, on violent and property crime. Results revealed that after controlling for city-wide crime trends and monthly fluctuations, violent crime declined significantly in Kendall-Whittier. Further analysis indicated that the possible crime-reducing effects of school investments on violent crime spread beyond Kendall-Whittier, and no displacement was found. The results for property crime were mixed. The study demonstrates the use of clustering analysis, a useful tool in neighborhood-level research to identify comparison neighborhoods. The findings shed light on the possibility that investments in early childhood schools can yield results in a shorter term than anticipated, making them a desirable component of urban revitalization. 相似文献

Bullet embolism is a relatively unusual complication of gunshot wounds. Embolism to the right atrium comprises <5% of all reported intravascular bullet emboli. We report an additional case of bullet embolus to the right atrium of a 0.38-caliber bullet following a gunshot wound to the chest. The intracardiac bullet was recognized radiologically on presentation, but the patient was hemodynamically stable and managed conservatively, with the bullet left in place. The missile remained within the heart without clinical significance for several years and was recovered from the right atrium only at the time of autopsy. To the best of our knowledge, this is the first documented case of a 0.38-caliber bullet which embolized to the right atrium and remained inconsequential for an extended period of time. 相似文献
