Adolescents’ defending of peers who are being bullied—or peer defending—was recently found to be a heterogeneous behavioral construct. The present study investigated individual differences in adolescents’ motivations for executing these indirect, direct, and hybrid defending behaviors. In line with the literature on bullying as goal‐directed strategic behavior, we adopted a social evolution theory framework to investigate whether these peer‐defending behaviors could qualify as goal‐directed strategic prosocial behaviors. A sample of 549 Dutch adolescents (49.4% boys; Mage = 12.5 years, SD = 0.6 years) participated in this study. Their peer reported defending behaviors (including bullying behavior as a control variable) and the following behavioral motivations were assessed: (a) agentic and communal goals (self‐report), (b) prosocial and coercive social strategies (peer report), and (c) altruistic and egocentric motivations for prosocial behavior (self‐report). The outcomes of hierarchical linear regression analyses suggest that adolescents’ motivations for executing the different subtypes of peer defending partially overlap but are also different. While indirect defending was fostered by genuine concerns for victims’ well‐being, direct defending was more motivated by personal gains. Hybrid defending combined favorable aspects of both indirect and direct defending as a goal‐directed, strategic, and altruistically motivated prosocial behavior. The implications of these findings are discussed. 相似文献
Eligible adolescents (12–17 years old) were recruited from a short‐term crisis shelter for runaway adolescents in a large Midwestern city. Adolescents (N = 179) were randomly assigned to Ecologically‐Based Family Therapy (EBFT, n =61), the Community Reinforcement Approach (CRA, n =57), or brief Motivational Enhancement Therapy (MET, n =61) with the primary focus on substance abuse. A significant increase in perceived family cohesion and a significant reduction in perceived family conflict were found among all treatment conditions from baseline to the 24‐month follow‐up. Adolescents who received EBFT demonstrated more improvement in family cohesion after treatment than those who received CRA or MET, and more reduction in family conflict during treatment than those who received MET. 相似文献
The negative effect of work-leisure conflict has attracted the attention of researchers. However, no previous research has determined the relationship between work-leisure conflict and ego depletion. Therefore, this study explores the relationship between daily work-leisure conflict and ego depletion, as well as the role of individuals’ negative emotions and core self-evaluations in this process based on ego depletion theory. Through the method of daily diary research, 77 employees were tracked for 7 consecutive work days. The results show that work-leisure conflict is positively related to employee ego depletion, that the negative emotions play a mediating role in this relationship and that core self-evaluations moderate the indirect effect of work-leisure conflict on ego depletion through negative emotions. In this study, daily diary method is used to verify the dynamic characteristics of work-leisure conflict, negative emotions and ego depletion, and some new insights into how to reduce employee ego depletion are provided.
Over the last decade the health and environmental research communities have made significant progress in collecting and improving access to genomic, toxicology, exposure, health, and disease data useful to health risk assessment. One of the barriers to applying these growing volumes of information in fields such as risk assessment is the lack of informatics tools to organize, curate, and evaluate thousands of journal publications and hundreds of databases to provide new insights on relationships among exposure, hazard, and disease burden. Many fields are developing ontologies as a way of organizing and analyzing large amounts of complex information from multiple scientific disciplines. Ontologies include a vocabulary of terms and concepts with defined logical relationships to each other. Building from the recently published exposure ontology and other relevant health and environmental ontologies, this article proposes an ontology for health risk assessment (RsO) that provides a structural framework for organizing risk assessment information and methods. The RsO is anchored by eight major concepts that were either identified by exploratory curations of the risk literature or the exposure‐ontology working group as key for describing the risk assessment domain. These concepts are: (1) stressor, (2) receptor, (3) outcome, (4) exposure event, (5) dose‐response approach, (6) dose‐response metric, (7) uncertainty, and (8) measure of risk. We illustrate the utility of these concepts for the RsO with example curations of published risk assessments for ionizing radiation, arsenic in drinking water, and persistent pollutants in salmon. 相似文献
