Although past research has developed scales for the incidence, prevalence, and fear of student-on-student victimization (SSV), little is known about the scaling of perceived risk (i.e., the cognitive appraisal of the chances of experiencing SSV). Hence, this study examined self-report survey data for the perceived risk of SSV as measured in the Adolescent Index for School Safety (AISS). Children in grades 7 through 10 (n=337) in a single Florida public school completed the AISS. Factor analyses using Maximum Likelihood Estimation with Oblimin Rotation identified nine unique factors for perceived risk. Reliability analyses found standardized Cronbach Alphas that ranged from .64 to .91, and seven out of the nine identified scales were above .80, which suggested good to excellent internal consistency. Future research should examine the content validity, construct validity, and predictive validity for the AISS and other self-report surveys of SSV dynamics. This publication was made possible by a grant [#97-MU-FX-KO12 (S-l)] from the Office of Juvenile Justice and Delinquency Prevention (O.J.J.D.P.), United States Department of Justice (U.S.D.O.J.). This grant is administered through the Hamilton Fish National Institute on School and Community Violence at George Washington University. This specific study was developed and implemented by staff at: 1) East Carolina University’s Department of Criminal Justice; and 2) Florida State University’s Center for Educational Research and Policy Studies. All points of view and opinions in this paper are those of the authors and do not necessarily represent the official position or policies of East Carolina University, Florida State University, the Hamilton Fish National Institute on School and Community Violence, the O.J.J.D.P., or the U.S.D.OJ. The authors would also like to thank Dr. Bill Doerner and Jennifer Jolley for their support, editorial feedback, and insightful comments regarding earlier drafts of this paper.  相似文献

Abstract.  The conventional literature on international cooperation in general, and intergovernmental organization membership in particular, depicts a regular, positive relationship between wealthy capitalist democracies and participation in international institutions. While empirical evidence supports this assertion, it says little about the mechanisms, and the accompanying variation among them, by which states enter into international institutions. This study distinguishes industrialized democracies along two dimensions: the nature of their constitutional structures and the organization of their electoral politics. Variations in these features produce variations in the institutional constraints and electoral incentives that matter in determining state participation in international organizations. Results of a pooled cross-sectional time series analysis of 23 democracies in 1981 and 1992 indicate that the structure of governing institutions and the nature of electoral systems account for much of the variation in intergovernmental organization membership. This study concludes that domestic institutions matter in determining international cooperation through international organizations – a novel insight overlooked by most international relations theories.  相似文献
