We explore the development of bullying and victimization in school by investigating 11‐, 13‐ and 15‐year‐olds' sense of interpersonal empowerment with parents, friends and teachers. A national sample of 4386 male and female students from 243 middle and secondary schools in Italy were surveyed. Boys were more likely than girls to be bullies and more likely to have been a bully/victim. Victimization and the likelihood of being both a bully and a victim declined with age. Bullying increased with age among boys whereas for girls it was slightly more prevalent at age 13 than ages 11 or 15. The sense of empowerment students experience with their teachers decreased in the older cohorts. Disempowered relationships with teachers consistently predicted bullying behaviour. Higher social competence was reported by 13‐ and 15‐year‐old bullies. Chronically bullied students had lower social competence in all age cohorts. Otherwise, predictors of victimization varied by age: 11‐year‐old victims felt less empowered by their teachers; 15‐year‐old victims reported more difficulties in negotiating cooperative relationships with parents. Bullies in all cohorts and younger bully/victims feel less empowered by their teachers. These findings suggest that students who are disempowered by teachers may either compensate by oppressing (bullying) peers or generalize the power differential with peers (become a victim).

With a sample of Italians selected from 71 Italian counties (N = 1,868), we performed two multilevel analyses aimed at predicting the perceived risk of crime at local (i.e., in the participants' county of residence) and at societal (i.e., in the context of Italian society) levels. A significant proportion of the variation in local risk perception was at the county level. The following individual variables predicted higher levels of this variable: indirect victimization, the perception of social and physical disorder, being a woman, being poorly educated, and being an older person. Among the ecological predictors, the crime rate and unemployment rate predicted higher levels of local crime risk perception, while the immigrant rate did not. Perceived risk of crime at the societal level did not show significant variation at the county level. Education, being a man, trusting people, and adhesion to post‐materialistic values predicted lower levels of societal crime risk perception, while number of sons/daughters and exposure to television news increased it. The limitations and possible development of this study are discussed. 相似文献

This study examined the association between two characteristics of school climate (sense of community and teacher support, measured both at the individual and at the school level) and students’ feelings of being unsafe at school. The study involved a sample of 49,638 students aged 10–18 years who participated in the 2010–2012 California Healthy Kids Survey. Using hierarchical linear modeling (HLM), our findings revealed that, at the individual level, students perceiving higher levels of sense of community and teacher support at school were less likely to feel unsafe within the school environment. At the school level, sense of community was negatively associated with unsafe feelings, whereas there was no association between school‐level teacher support and feelings of being unsafe at school. 相似文献

The present research aimed at expanding Pierro, Kruglanski, and Raven’s work examining the interweaving between the need for closure (NFC; the desire to form quick and unambiguous knowledge) and the Interpersonal Power Interaction model. In particular, this study explored the idea that the greater compliance to harsh power tactics of subordinates’ employees, that are high on NFC, can increase when their desire to achieve cognitive closure is made more salient by a high (compared to low) level of perceived job demands. A sample of 280 subordinates employees belonging to two different organizational contexts filled in a self-report questionnaire. Through a moderation and simple slope analyses, we tested and confirmed our hypothesis. When job demands were high, it potentially impaired the subordinates’ chance to form a quick knowledge. As a result, high NFC subordinates showed a higher compliance with harsh power tactics. Such tactics, limiting the subordinates’ freedom of choice, can be conceived as a means to gain quick knowledge when the organizational context is perceived as particularly demanding. As far as practical implications, these results suggest that for high NFC subordinates the use of more directive and unambiguous guidelines (e.g., harsh power tactics) could minimize the scarcely tolerated cognitive cost associated with high job demands. 相似文献

Automatic verification of multi-agent systems by model checking via ordered binary decision diagrams 总被引：1，自引：0，他引：1
We present a methodology for the verification of multi-agent systems, whose properties are specified by means of a modal logic that includes a temporal, an epistemic, and a modal operator to reason about correct behaviour of agents. The verification technique relies on model checking via ordered binary decision diagrams. We present an implementation and report on experimental results for two scenarios: the bit transmission problem with faults and the protocol of the dining cryptographers. 相似文献

Two studies were conducted using the Buss aggression machine paradigm to investigate the mediational role of physical exercise with respect to subsequent aggression in relation to the presence or absence of previous instigation. The irritability level of subjects was taken into account in the first study, and the subject' emotional susceptibility level in the second study. In both studies sex differences were also considered so that each study resulted in a 2 × 2 × 2 × 2 design with ten subjects in each cell. As far as irritability is concerned, experimental subjects (pedaling on a bicycle ergonometer) delivered higher shocks than controls (who just waited out the 10 min the experimental subjects were pedaling), independent of irritability level or of the presence or absence of previous instigation. When emotional susceptibility was taken into consideration, physical exercise associated with high level of emotional susceptibility and previous instigation resulted in increased intensity of the shocks subsequently delivered. These findings are discussed in terms of the importance of stable personality characteristics that may differentially mediate aggression. 相似文献

Civic engagement, defined as involvement in community life, is influenced by reciprocal relationships between individuals and contexts and is a key factor that contributes to positive youth development. The present study evaluates a theoretical model linking perceived democratic school climate with adolescent civic engagement (operationalized as civic responsibility and intentions for future participation), taking into account the mediating role of civic discussions and perceived fairness at school. Participants were 403 adolescents (47.9 % male) ranging in age from 11 to 15 years old (mean age = 13.6). Path analysis results partially validated the proposed theoretical model. Higher levels of democratic school climate were associated with higher levels of adolescent civic responsibility; the association was fully mediated by civic discussions and perceived fairness at school. Adolescents’ civic responsibility, then, was positively associated with a stronger intention to participate in the civic domain in the future. 相似文献

We performed a multilevel, multinational test of Stenner's model on authoritarianism using the 2008 European Values Survey dataset (N = 55 199, nested in 38 nations). We focussed on the effects exerted on four authoritarian manifestations (racial intolerance, political intolerance, negative attitudes towards immigrants, and moral intolerance) by the cross‐level interaction between participants' authoritarian predispositions (assessed in terms of childrearing values) and their country's crime rate. Associations between authoritarian predispositions and racial intolerance, political intolerance, negative attitudes towards immigrants, and moral intolerance were significantly stronger among participants living in countries characterised by high crime rates than those among participants living in countries with low crime rates. Limitations, implications, and future directions of this study are discussed. Copyright © 2013 European Association of Personality Psychology. 相似文献

Influences of different sources of social support (from parents and friends), school sense of community, and self-efficacy on psychosocial well being (as measured by self-reported life satisfaction and psychological symptoms) in early adolescence were investigated in an integrative model. The model was tested using structural equation modeling. Multi-group comparisons were used to estimate differences between sex and age groups. The survey sample was composed of 7,097 students in Northern Italy (51.4% male) divided into three age cohorts (equivalent to 6th, 8th, and 10th grades with median ages of 11, 13, and 15). Findings obtained using SEM were consistent with self-efficacy and school sense of community mediating effects of social support on psychosocial adjustment. The multi-group comparison indicates a need for more complex developmental models and more research on how changing forms of support interact with each other as their effects also change during this important stage of the life. Implications for primary prevention and cross-cultural comparisons are discussed. 相似文献
