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

研究以心理健康双因素模型为视角,运用元分析技术梳理了留守儿童歧视知觉与积极和消极心理健康的关系,并探究了影响其关系的调节变量。通过文献检索与筛选,共27篇中英文文献,56个独立样本纳入元分析,包含被试17146名。结果显示,歧视知觉与积极心理健康指标呈显著的负相关关系(r=-0.298),与消极心理健康指标呈显著的正相关关系(r=0.365)。调节效应分析发现,留守儿童歧视知觉与积极心理健康的关系受到歧视知觉测量工具的影响,与消极心理健康的关系受到歧视知觉测量工具、学龄段以及消极结果类型的影响。同时,元回归分析发现,文献年份对歧视知觉与积极心理健康指标关系的调节效应显著; 性别对歧视知觉与积极和消极心理健康关系的调节作用均不显著。研究结果进一步明确了留守儿童歧视知觉与积极和消极心理健康的关系,为探索提升留守儿童心理社会适应的新路径提供了借鉴。  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

Jung was highly committed to grasping the meaning of psychotic thinking, and left behind precious insights to treatment scattered through his works written between 1906 and 1958. The tendency of today's psychiatry is to attribute the psychotic process to alteration in the brain's anatomy, biochemistry and electrophysiology, thus exempting the subject, i.e. the afflicted person, from responsibility for attachment to reality and their sanity. Jung understood schizophrenia as an ‘abaissement du niveau mental’, a similar phenomenon to the one encountered in dreams, and caused by a peculiar ‘faiblesse de la volonté’. He contested that complexes in schizophrenia, in contrast with neurotic disorders, are disconnected and can either never reintegrate to the psychic totality or can only join together in remission ‘like a mirror broke into splinters’ (Jung 1939 , para. 507). Accordingly, a person who does not fight for the supremacy of ego consciousness and has let themself be swayed by the intrusion of alien contents arising from the unconscious (even to the point of becoming fascinated by regression) is exposed to the danger of schizophrenia. The contemporary relevance of these notions and their necessity in understanding the psychotic process in the light of modern scientific findings are discussed.  相似文献

随机选取某市三所普通中小学四、六、八、十年级的755名青少年为被试,使用自评和他评问卷探讨家庭亲密度、家庭道德情绪和责任感与青少年学校适应之间的关系。结果显示:(1)青少年家庭亲密度、责任感与学校适应问题存在性别差异,女生家庭亲密度和责任感高于男生,外化和学业问题少于男生;家庭亲密度、道德情绪和责任感随年龄增长呈下降趋势;(2)家庭亲密度正向预测道德情绪和责任感,直接和间接负向预测青少年学校适应问题。(3)责任感负向预测学校适应问题,并在家庭亲密度和学校适应问题之间起部分中介作用;结构方程模型各指标的拟合效果较好。家庭亲密度、责任感是学校适应问题的良好预测指标。  相似文献

This paper examines the links between acting upon a duty to assist, responsibility for these actions, and how such actions link with incremental moral duties that can amass as a consequence of such action. More specifically, this paper is concerned with practices of international aid and assistance, whereby public and privately funded donations enable the actions of parties outside of the territorial and jurisdictional boundaries of a community and state to directly influence the functioning of that community, and the incremental moral duties to which such action can give rise. Using a Senian account of the basis of moral duty, it explains how agents are responsible for the outcomes of their acts of assistance, even when mediated through international institutional actors, and how such acts can give rise to accumulative duties and obligations that are not bound or constrained by territorial boundaries or pre-existing special obligations.  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
