Feeling support from the community is a vital aspect of adolescents’ quality of life. Negative experiences at school, such as bullying and cyberbullying can have an adverse impact on adolescents’ life satisfaction that can expand to different domains of their lives including community variables. The goal of the present study was to examine the association between peer victimization, life satisfaction and community support among Chilean adolescents. We used a sample of 497 youths enrolled in grades 9 to 12 of public and private schools in different Chilean districts. Results indicate a negative association between bullying and cyberbullying behavior on community support through life satisfaction. Peer victimization can have negative consequences for youths at a personal level on their assessments of life satisfaction, which can expand to feeling less support from the community. Feeling less support from the community can be detrimental to healthy youth development and adolescents’ quality of life. Community prevention efforts can thus provide emotional support for youth victims of bullying and cyberbullying.
Across two studies, we found evidence supporting a positive feedback loop between positive activities, kindness and well-being. In Study 1, participants were randomly assigned to one of four distinct positive activities (versus a neutral writing activity) before spending three weeks engaging in kind acts. We found that the positive activities served as triggers – that is, they predicted greater prosocial effort, which in turn predicted greater well-being immediately following the intervention and at a two-week follow-up. In Study 2, we explored the specific effects of a gratitude trigger, and extended the intervention period to six weeks. Although, we did not replicate the direct effect of the gratitude trigger on prosocial effort, people who wrote gratitude letters (versus writing about their week) reported relatively greater elevation, which predicted greater prosocial effort during the six weeks. In turn, replicating Study 1, greater effort predicted higher well-being immediately following the study. 相似文献
Although a group of people working together recalls more items than any one individual, they recall fewer unique items than the same number of people working apart whose responses are combined. This is known as collaborative inhibition, and it is a robust effect that occurs for both younger and older adults. However, almost all previous studies documenting collaborative inhibition have used stimuli that were neutral in emotional valence, low in arousal, and studied by all group members. In the current experiments, we tested the impact of picture-stimuli valence, picture-stimuli arousal, and information distribution in modulating the magnitude of collaborative inhibition. We included both younger and older adults because there are age differences in how people remember emotional pictures that could modulate any effects of emotion on collaborative inhibition. Results revealed that when information was shared (i.e., studied by all group members), there were robust collaborative inhibition effects for both neutral and emotional stimuli for both younger and older adults. However, when information was unshared (i.e., studied by only a single group member), these effects were attenuated. Together, these results provide mixed support for the retrieval strategy disruption account of collaborative inhibition. Supporting the retrieval strategy disruption account, unshared study information was less susceptible to collaborative inhibition than shared study information. Contradicting the retrieval strategy disruption account, emotional valence and arousal did not modulate the magnitude of collaborative inhibition despite the fact that participants clustered the emotional, but not neutral, information together in memory. 相似文献
While everyone deals with stressful situations on a daily basis, individuals have different behavioral reactions to that stress. We argue that life stress also affects individuals’ political behavior, but this effect is contingent on their past political involvement. While individuals familiar with and engaged in the political process are unaffected when confronted with stress in life, individuals who are not routinely involved in the electoral process are more likely to disengage from politics. To test the differential effects of stress on the likelihood of political involvement, we fielded two experiments, one preceding the U.S. presidential election of 2012 and the second preceding the 2013 municipal election in a small Midwestern American town. We find that when triggered to consider life stressors unrelated to politics, individuals without a history of past participation in politics are less likely to vote while individuals who are habitual voters are unaffected. 相似文献
Based on a study conducted in a large corporation (XINC, a pseudonym) and other research, it appears that performance management
can be used to increase levels of employee engagement. We begin this article with a discussion of employee engagement, define
engaged employees as those who feel involved, committed, passionate, and empowered, and demonstrate those feelings in work
behavior. We then discuss an expanded view of performance management, conceptualizing it as five major activities that serve
to organize relevant behaviors shown to be either direct or indirect predictors of employee engagement in the study at XINC.
These major activities include setting performance and development goals, providing ongoing feedback and recognition, managing
employee development, conducting mid-year and year-end appraisals, and building a climate of trust and empowerment. In turn,
we briefly discuss how each of these major activities contributes to employee engagement, suggest which activities benefit
from further research, and recommend possible studies. Although there is evidence for performance management as a driver of
employee engagement, we conclude there is a need for additional research that clarifies for managers which of these activities
have the strongest impact on employee engagement. 相似文献
When disaster disrupts healthcare and other systems, the ethical allocation of resources should follow principles of justice, defined as fairness, established for normal clinical practice. Standards of clinical practice may be altered during disaster, but ethical standards must remain centered on prioritizing the treatment of patients according to need and the effectiveness of treatment. Should resources become extremely limited, it is fair to restrict their use to patients who have the highest needs, provided that the intervention is effective. When resources become more available, patients with lower priority can be increasingly accommodated. 相似文献
