Five political generations in the U.S. national electorate are identified utilizing the theory of operant conditioning. The party identification of 11,312 white registered voters from the 1980New York Times/CBS News poll series is examined for these generations within social status (education) groupings. 相似文献

This black box study assessed the performance of forensic firearms examiners in the United States. It involved three different types of firearms and 173 volunteers who performed a total of 8640 comparisons of both bullets and cartridge cases. The overall false-positive error rate was estimated as 0.656% and 0.933% for bullets and cartridge cases, respectively, while the rate of false negatives was estimated as 2.87% and 1.87% for bullets and cartridge cases, respectively. The majority of errors were made by a limited number of examiners. Because chi-square tests of independence strongly suggest that error probabilities are not the same for each examiner, these are maximum-likelihood estimates based on the beta-binomial probability model and do not depend on an assumption of equal examiner-specific error rates. Corresponding 95% confidence intervals are (0.305%, 1.42%) and (0.548%, 1.57%) for false positives for bullets and cartridge cases, respectively, and (1.89%, 4.26%) and (1.16%, 2.99%) for false negatives for bullets and cartridge cases, respectively. The results of this study are consistent with prior studies, despite its comprehensive design and challenging specimens. 相似文献

Research suggests that the safer students feel at school, the more likely they are to feel connected and able to focus on learning. Thus, measuring students’ experiences with a school safety officer (SSO) is essential to understand the connection between officer engagement and students’ safety. This study’s purpose was to evaluate a SSO scale among 1,065 adolescents. Results suggest the SSO scale displayed excellent internal consistency estimates, construct validity via factor analysis, convergent validity with the School Climate Measure, discriminant validity with key demographic variables, and known-groups validity among students who reported fighting at school. Positive perceptions of SSOs also significantly increased with frequency of contact. The SSO scale is a preliminarily valid measure, potentially useful in research, screenings, and/or evaluation efforts to improve student engagement with SSOs. 相似文献

This paper takes a critical view of Rancière’s ideas on politics, subjectivity, and space by building on the criticisms offered by Alain Badiou in a series of critical exchanges between the two authors. The first part of the paper reviews the main points of difference between them, which centre around their different interpretations of what constitutes a political event, subjectivity, and the nature of radical politics. Later sections then develop these differences with respect to further issues concerning the nature of political spaces, the pre-evental, and political organization. 相似文献

Do Networks Really Work? A Framework for Evaluating Public‐Sector Organizational Networks 总被引:4,自引:0,他引:4
Although cooperative, interorganizational networks have become a common mechanism for delivery of public services, evaluating their effectiveness is extremely complex and has generally been neglected. To help resolve this problem, we discuss the evaluation of networks of community-based, mostly publicly funded health, human service, and public welfare organizations. Consistent with pressures to perform effectively from a broad range of key stakeholders, we argue that networks must be evaluated at three levels of analysis: community, network, and organization/participant levels. While the three levels are related, each has its own set of effectiveness criteria that must be considered. The article offers a general discussion of network effectiveness, followed by arguments explaining effectiveness criteria and stakeholders at each level of analysis. Finally, the article examines how effectiveness at one level of network analysis may or may not match effectiveness criteria at another level and the extent to which integration across levels may be possible. 相似文献
