Research has indicated that school factors such as communal school organization and student bonding are predictive of school disorder, with greater communal organization and greater student bonding leading to less delinquency and victimization. Data from a nationally representative sample of 254 public, nonalternative, secondary schools were used to examine structural equation models representing hypothesized relationships among communal school organization, student bonding, and school disorder. The hypothesis that communally organized schools would have less disorder held true for teacher victimization and student delinquency, but not for student victimization. In addition, the hypothesis that the relationship between communal school organization and school disorder would be mediated by student bonding was supported for student delinquency, but not for teacher victimization. 相似文献

Although many different analyses in some ways acknowledge the relevance of labour markets to the political economy of violent conflict and of war to peace transitions, there has been little sustained or systematic exploration of this dimension of war economies and post-conflict reconstruction. This paper highlights the empirical and analytical gaps and suggests that a framework departing from the assumptions of the liberal interpretation of war allows for a richer analysis of labour market issues and policies. This is illustrated by the history of rural Mozambique through the war economy and into the first post-war decade. 相似文献

Offender assessment and classification is becoming an increasingly important part of correctional supervision and intervention. Over the last several decades, several different methods and “generations” of offender classification have emerged. Of most value appear to be third-generation, actuarial, dynamic risk/need assessments. With any new correctional strategy, however, there is a need to investigate the use of these risk/need assessments on offender subgroups in order to inform issues, such as reliability and prevalence of criminogenic risk factors. The present study utilized data that were gathered using the Level of Service Inventory-Revised (LSI-R). Results and comparisons of these assessments were investigated and presented for Native American and non-Native American offenders as well as male and female offenders. Discussion of the results, implications, and recommendations for further research are presented. 相似文献

This paper highlights some of the central ethical challengesinvolved in undertaking social science research with refugeesin conflict and crisis situations. It focuses on two main setsof challenges: first, the difficulties of constructing an ethicalconsent process and obtaining genuinely informed consent; andsecond, taking fully into account and responding to refugeeparticipants' capacities for autonomy. The authors also discussthe challenges involved in applying the central normative principlesgoverning ethics review processes—the principles of beneficence,integrity, respect for persons, autonomy and justice—tothe context of refugee research. It is argued that researchersshould seek ways to move beyond harm minimization as a standardfor ethical research and recognize an obligation to design andconduct research projects that aim to bring about reciprocalbenefits for refugee participants and/or communities. Some ofthe methodological issues raised by this analysis are discussedin the conclusion. 相似文献
