Although the predictors of off-line relational aggression have been examined in prior work, less is known about the factors that contribute to online relational aggression perpetration and victimization. This study examined parental restrictive and active mediation of teenagers’ social media use as potential predictors of these outcomes. We were particularly interested in understanding whether parental agreement about media rules and the consistency with which mediation was implemented had implications for teens’ social media use, conflict with parents, and experience with online relational aggression. We conducted an online survey of 814 adolescents from the United States (14- to17-year-olds), asking about perceived agreement between parents about media rules, parental mediation styles, the teens’ social media use, and their experiences with online relational aggression. Results showed that parental rule agreement negatively predicted inconsistent parental mediation. Inconsistent parental mediation predicted more adolescent social media use and more parent-teen conflict over media rules, which in turn, predicted both online victimization and perpetration.  相似文献

The present study was designed to examine the effectiveness of Fatal Vision Goggles in reducing intentions to drink and drive. Participants performed a field sobriety task and drove in a traffic simulator while wearing the goggles. A regression analysis was performed in order to predict changes in intentions to drink and drive, using typical drinking patterns, perceived likelihood of getting into a collision when drinking and driving, self efficacy, and driving independence as predictor variables. Results showed that drinking and driving intentions were reduced following the use of Fatal Vision Goggles among those that typically drink more during outings, among those that believe the likelihood of collisions when drinking and driving are greater, and among those less likely to drive to achieve independence and autonomy. These results indicate that Fatal Vision Goggles can be an effective tool in altering drinking and driving attitudes among drivers with specific attitudinal and personal characteristics.  相似文献

Objective: Previous research has established a gap in orgasm frequency between men and women. This study investigates explanations for the gender gap in orgasm. Methods: Crosstab analysis and logistic regression are used to examine the gender gap in orgasms from one Canadian city: Hamilton, Ontario (N = 194). Results: We find a strong association between women’s orgasms and the type of sexual behavior in which partners engage. Women who receive oral sex are more likely to reach orgasm. Conclusion: Sexual practices focused on clitoral stimulation are important to reducing the gender gap in orgasms.  相似文献

This paper describes a pilot project to develop an effective applied learning experience for graduate social work students. An asset-based social justice model was used as a guide in the development of the project. Importance was placed on the host community determining its own needs and the contributions the students would provide. A partnership with community stakeholders was developed. The stakeholders decided the needs to be addressed and the faculty prepared the students to meet those needs. Successes and limitations of the pilot project are reviewed.  相似文献

Children's participation in legal proceedings affecting them personally has been gaining importance. So far, a primary research concern has been how children experience their participation in court proceedings. However, little is known about the child's voice itself: Are children able to clearly express their wishes, and if so, what do they say in child protection cases? In this study, we extracted information about children's statements from court file data of 220 child protection cases in Germany. We found 182 children were asked about their wishes. The majority of the statements found came either from reports of the guardians ad litem or from judicial records of the child hearings. Using content analysis, three main aspects of the statements were extracted: wishes concerning main place of residence, wishes about whom to have or not contact with, and children granting decision‐making authority to someone else. Children's main focus was on their parents, but others (e.g., relatives and foster care providers) were also mentioned. Intercoder agreement was substantial. Making sure that child hearings are as informative as possible is in the child's best interest. Therefore, the categories developed herein might help professionals to ask questions more precisely relevant to the child.  相似文献

The implications of constrained dependent and independent variables for model parameters are examined. In the context of linear model systems, it is shown that polyhedral constraints on the dependent variables will hold over the domain of the independent variables when a set of polyhedral constraints is satisfied by the model parameters. This result may be used in parameter estimation, in which case all predicted values of the dependent variables are consistent with constraints on the actual values. Also, the implicit constraints that define the set of parameters for many commonly used linear stochastic models with an error term yield values of the dependent variables consistent with the explicit constraints. Models possessing these properties are termed “logically consistent”.  相似文献
