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

The purpose of this study is to review 23 causes of death that have occurred in Western-Austrian prisons from 1974 to 1989. The majority of them (11 cases) were due to suicides. Among 9 cases of natural death there was a 25 years old man, who died of an unknown purulent meningoencephalitis. Two drunken prisoners had not been supervised and therefore died of alcohol poisoning. In one case the police jail physician did not recognize an epidural hematoma.  相似文献

This paper gives the author's impressions on the following aspects of justice: desert, equity, equality, need, and intergenerational equity. The author concludes that these different aspects cannot be reconciled but instead must be compromised. An example of such a compromise is provided by a discussion of welfare reform. The author claims that rights are correlative with duties, and that asserting the former has little meaning without specifying the latter. He then discusses justice toward groups rather than individuals. He proposes that maintaining cultural variety in the presence of a homogeneous superculture is a major problem of the contemporary world. The paper concludes with a discussion of various forms of power, particularly the integrative power that people acquire over each other by virtue of ties of loyalty and identity.  相似文献
