The role of physical and relational aggression in adolescents' friendship selection was examined in a longitudinal sample of 274 Chilean students from 5th and 6th grade followed over 1 year. Longitudinal social network modeling (SIENA) was used to study selection processes for aggression while influence processes were controlled for. Furthermore, the effects of network characteristics (i.e., reciprocity and transitivity), gender, and social status on friendship selection were examined. The starting assumption of this study was that selection effects based on aggression might have been overestimated in previous research as a result of failing to consider influence processes and alternative characteristics that steer friendship formation. The results show that selection effects of both physical and relational aggression disappeared when network effects, gender, and social status were taken into account. Particularly gender and perceived popularity appeared to be far more important determinants of friendship selection over time than aggression. Moreover, a peer influence effect was only found for relational aggression, and not for physical aggression. These findings suggest that similarity in aggression among befriended adolescents can be considered to be mainly a by-product rather than a leading dimension in friendship selection.  相似文献

Guided by the theory of motivated information management, this study investigated the extent to which Singaporean college students' sexual health information‐seeking behaviour could be accounted for by their anxiety of uncertainty discrepancy, their perceived outcomes of information seeking and their perceived confidence in seeking and coping with sexual health information acquired from their best friends. Taking into account that issue relevance may play a role in individuals' health decision‐making, this study also examined the effect of perceived vulnerability on respondents' sexual health information‐seeking behaviour. An online survey was conducted with 202 undergraduate students at a university in Singapore. Respondents were asked to report the frequency with which they sought four types of sexual health information from their best friends: unwanted pregnancy, abortion, HIV/AIDS and other sexually transmitted infections. Survey data showed that respondents' uncertainty discrepancy was positively associated with their anxiety. Anxiety had negative effects on efficacy and outcome expectancy. Outcome expectancy was positively associated with efficacy. Both efficacy and perceived vulnerability accounted for a significant amount of variance in respondents' sexual health information‐seeking behaviour. Findings from this study contribute to a better understanding of young adults' sexual health information behaviour in a Singapore context.  相似文献

共有消费是多位消费者共同参与并承担开销的一种常见的消费活动。本研究基于风险转移理论, 探究了消费情境(单独消费vs.共有消费)对不熟悉产品偏好的作用机理及边界条件。通过5个实验, 结果发现:相比于单独消费情境下的消费者, 在共有消费情境下的消费者更愿意尝试不熟悉的产品。原因在于共有消费情境会转移消费风险, 使得消费者对不熟悉产品的感知风险降低。但是该效应仅发生于产品风险较低的产品。同时, 当共有消费群体的关系较为疏远时, 该效应会消失甚至逆转。  相似文献

Dental education programs are known to be highly stressful and stress can affect general health. The aims were to identify sources of stress among preclinical students and to evaluate their perceived levels of stress, self-efficacy and effective coping strategies in a private dental school. One hundred preclinical students in a Turkish private dental school were surveyed using dental environment stress (DES), perceived stress (PSS), general self-efficacy (G-SES) and brief coping scales (Brief-COPE). Age, gender, history of psychiatric treatment, factors that affected the choice of dentistry, choice rank of dental school, scholarship and income was recorded. ‘Exams and grades’ followed by ‘Fear of failing course or year’ were found to be the most stressprovoking factors. The most and the least stressprovoking DES domains were ‘Workload’ and ‘Social stressors’, respectively. ‘Social stressors’ affected male more than female (p < .05). The most and the least common coping strategies were found to be ‘Planning’, and ‘Drug’, respectively. Female used ‘Instrumental support’ more than male (p < .05). Demographic factors had impact on the perceived stress factors and levels, as well as coping strategies. Unlike previous studies establishing high stress levels in dental students, preclinical students displayed moderate level of stress. Clinical dental education might be more responsible for creating stress.  相似文献

In recent years, the Netherlands has been frequently confronted with public incidents of anti-Semitism and Islamophobia. After defining the complex concepts of anti-Semitism and Islamophobia, presenting the theoretical approach to these phenomena, and sketching the societal context in which they are embedded, this article describes the development of the numbers of reported expressions of anti-Semitism and Islamophobia in the Netherlands since the turn of the century. It notes that the general level of annual numbers of recorded incidents of the phenomena has increased since 2000 and, at the same time, there are significant fluctuations in the numbers of notified incidents per year. These fluctuations correlate to outbursts of violence in the Middle East and to acts of violence committed in the name of Islam in the West, while the general higher level of incidents of anti-Semitism and Islamophobia relates to numerous and various threats experienced in the context of the Dutch multi-ethnic society, changes in national identity, and trends in globalisation.  相似文献

The present research investigates how intergroup apologies, defined as apologies between two groups, affect perceived remorse and outgroup attitudes (e.g., explicit and implicit), in the context of power asymmetries. We recruited participants from two countries that differ in perceived power: South Korea and the United States. Participants read a vignette describing a violent act committed by an outgroup member (Korean or American), with or without an intergroup apology. Participants answered questions assessing perceived remorse and explicit attitudes toward the outgroup, followed by the Implicit Association Test (Greenwald, McGhee, & Schwartz, 1998). Results revealed that Koreans perceived less remorse following an intergroup apology from the United States, compared to when they did not read an intergroup apology. Further, a mediated moderation analysis indicated that perceived remorse mediated the relationship between apology and explicit attitudes towards the United States. However, an analogous effect for implicit attitudes was only marginally significant. In contrast, among American participants, no effect of the apology on perceived remorse, explicit attitudes, or implicit attitudes and no evidence for a mediation was found. We discuss the implications of these effects on understanding the effectiveness of intergroup apologies between countries that differ in perceived power.  相似文献

下属默契指的是下属与上司间不经言传而暗相投合的状态,它能潜移默化地提升下属绩效。因此,探讨下属默契的产生原因,对组织有着重要意义。鉴于此,本文以目标动机模型为理论基础,探讨了上司地位知觉对下属默契的影响及其内部机制。通过对186名企业员工的调查分析发现,上司地位知觉对下属默契有显著的正向影响;反馈寻求行为在此过程中起部分中介作用;此外,下属的观点采择能力调节了反馈寻求行为与下属默契间的正向关系。  相似文献

Background and Objective: This research examines the detrimental effects of workplace bullying as a social stressor on employees’ job performance, organizational retaliatory behaviors, and organizational citizenship behaviors and how the availability of support can reduce the negative impact of bullying. Using social exchange theory and the conservation of resources theory as theoretical frameworks, we propose that workplace bullying drains personal resources, leading to reduced job performance, low citizenship behaviors, and increased organizational retaliatory behaviors. We also propose that perceived organizational support acts as moderator, such that it reduces the detrimental effects of bullying on employee behaviors.

Research Design and Methods: We tested our hypotheses in two field studies (N?=?478 and N?=?395) conducted in Pakistan.

Results: The results of both studies supported the assertion that workplace bullying exacerbates employees’ job performance, reduces organizational citizenship behaviors and intensifies organizational retaliatory behaviors. The idea that perceived organizational support would moderate the bullying-work behavior relationships found mixed support. While perceptions of organizational support reinforced the bullying-job performance and bullying-retaliatory behaviors relationships, it did not moderate the bullying-citizenship behaviors relationship in the suggested direction.

Conclusion: The findings show that workplace bullying leads to more organizational citizenship behaviors when employee’s perceptions of organizational support is high.  相似文献

Background and objectives: Workplace ostracism research has examined numerous underlying mechanisms to understand the link between workplace ostracism and behavioral outcomes. Ostracism has been suggested to be an interpersonal stressor; however, research has not investigated workplace ostracism from a stress perspective. Therefore, the study investigated the mediating effect of perceived stress for the relationships between workplace ostracism and helping behavior, voicing behavior, and task performance. The study also investigated the moderating effect of psychological empowerment for the relationships between perceived stress and behavioral outcomes.

Design: The study design was a three-wave self-reported questionnaire.

Method: The study sampled 225 full-time employees in South Korea and regression analyses with bootstrapping were conducted to test the moderated mediation models.

Results: The bootstrapped 95% CI around the indirect effects did not contain zero; therefore, perceived stress mediated the relationship between workplace ostracism and helping behavior (–.06), voicing behavior (–.07), and task performance (–.07). Further, the moderated mediation analyses found perceived stress mediated the relationships between workplace ostracism and behavioral outcomes only when individuals perceived low levels of psychological empowerment.

Conclusion: The findings suggest that workplace ostracism is a stressor and psychological empowerment can mitigate the negative effects of ostracism on behavioral outcomes.  相似文献
