Scholars have long argued that international organizations solve information problems through increased transparency. This article introduces a distinct problem that instead requires such institutions to keep information secret. We argue that states often seek to reveal intelligence about other states' violations of international rules and laws but are deterred by concerns about revealing the sources and methods used to collect it. Properly equipped international organizations, however, can mitigate these dilemmas by analyzing and acting on sensitive information while protecting it from wide dissemination. Using new data on intelligence disclosures to the International Atomic Energy Agency and an analysis of the full universe of nuclear proliferation cases, we demonstrate that strengthening the agency's intelligence protection capabilities led to greater intelligence sharing and fewer suspected nuclear facilities. However, our theory suggests that this solution gives informed states a subtle form of influence and is in tension with the normative goal of international transparency. 相似文献

It is often held that one function served by evaluation in the fields of education and social policy generally is to assist the administrator in the making of rational decisions. If, under these circumstances, several evaluators come to different conclusions about a research proposal or a pilot social program, on what basis can the administrator make his decision? He can hardly be expected to resolve any technical dispute between the experts who are his advisors. After discussing the various functions of the evaluation process, and analyzing some of the factors that may lead to such lack of consensus amongst experts, the paper recommends that if the administrator is concerned solely with making a rationally defensible decision, then he should select his evaluating panel so that all members share the same theoretical orientation. 相似文献

Only the best manufacturers will remain competitive in today's challenging environment. Any manager involved with developing new products knows the excitement, complexity, and risk of this unpredictable undertaking. Based upon findings from four world class manufacturers of medical imaging technology in Japan and the United States, this article presents a new organizing framework for integrating external information into the NPD process. The findings are particularly timely in an era when manufacturers are vulnerable to intense global competition. The article concludes with several implications for managers involved in the new product development process. 相似文献

Abstract: The purpose of this study was to outline a method by which an antemortem photograph of a victim can be critically compared with a postmortem photograph in an effort to facilitate the identification process. Ten subjects, between 27 and 55 years old provided historical pictures of themselves exhibiting a broad smile showing anterior teeth to some extent (a grin). These photos were termed “antemortem” for the purpose of the study. A digital camera was used to take a current photo of each subject’s grin. These photos represented the “postmortem” images. A single subject’s “postmortem” photo set was randomly selected to be the “unknown victim.” These combined data of the unknown and the 10 antemortem subjects were digitally stored and, using Adobe Photoshop software, the images were sized and oriented for comparative analysis. The goal was to devise a technique that could facilitate the accurate determination of which “antemortem” subject was the “unknown.” The generation of antemortem digital overlays of the teeth visible in a grin and the comparison of those overlays to the images of the postmortem dentition is the foundation of the technique. The comparisons made using the GrinLine Identification Technique may assist medical examiners and coroners in making identifications or exclusions. 相似文献

This paper examines a demand-side intervention that significantly increased access to maternal health services in rural Zambia in a context where skilled birth attendance rates had been stagnant for over two decades. Aspects of the intervention design that were crucial to the programme's success were the participatory and adult learning-centred approach used to mobilise intervention communities, the use of a community volunteer model, and the design's sensitivity and responsiveness to underlying social factors and problems. The demand-side intervention is already being scaled up in six districts, and is highly suitable for national level scale-up. 相似文献
