The current study examines whether being high in gender typicality is associated with popularity, whether being low in gender typicality is associated with rejection/teasing, and whether teasing due to low gender typicality mediates the association with negative mental health. Middle school children (34 boys and 50 girls) described hypothetical popular and rejected/teased peers, and completed self‐report measures about their own gender typicality, experiences with gender‐based teasing, depressive symptoms, anxiety, self‐esteem, and body image. Participants also completed measures about their peers' gender typicality, popularity, and likeability. Results indicated that popular youth were described as more gender typical than rejected/teased youth. Further, being typical for one's gender significantly predicted being rated as popular by peers, and this relationship was moderated by gender. Finally, low gender typicality predicted more negative mental health outcomes for boys. These relationships were, at times, mediated by experiences with gender‐based teasing, suggesting that negative mental health outcomes may be a result of the social repercussions of being low in gender typicality rather than a direct result of low typicality. 相似文献

Anchored in self‐determination theory (SDT), we used a sample of 310 Japanese father‐child dyads (fathers Mage = 47.95; children Mage = 14.98, 50% female), to investigate: (a) the structure of aspirations in a Japanese sample, (b) the association between fathers’ own intrinsic and extrinsic aspirations and the aspirations reported by their adolescent children, (c) the links between child‐reported father autonomy support and children’s self‐ reported aspirations, and (d) the associations between fathers’ own and children’s own aspirations and the basic psychological needs satisfaction of both fathers and children. Confirmatory factor analysis demonstrated acceptable fit for the theorized model of intrinsic and extrinsic aspirations specified by SDT. Correlation analysis revealed positive associations between the aspirations of fathers’ and those endorsed by their children, which were not moderated by father’s autonomy support. Actor‐partner interdependence modeling indicated that when fathers were relatively intrinsic in their orientations, basic psychological need satisfaction was higher for both themselves and their children. These findings highlight the relevance of intrinsic and extrinsic aspirations to the well‐being of youth and the interplay between fathers’ and children’s aspirations, suggesting that both fathers’ intrinsic aspirations and parenting styles are associated with children’s basic psychological needs satisfaction. 相似文献

We present a new inverse sampling design for surveys of rare events, Gap-Based Inverse Sampling. In the design, sampling stops if after a predetermined interval, or gap, no new rare events are found. The length of the gap that follows after finding a rare event is used as a way of limiting sample effort. We present stopping rules using decisions based on the gap length, the total number of rare events found, and a fixed upper limit of survey effort. We illustrate the use of the design with stratified sampling of two biological populations. The design uses the intuitive behavior of a field biologist in stratified sampling, where if in a stratum nothing is found after a long search, the field surveyor would like to consider the stratum is empty and stop searching. Our design has appeal for surveying rare events (for example, a rare species) with stratified sampling where there are likely to be some completely empty strata. 相似文献

Theory of mind (ToM) and empathy are separate, but related components of social understanding. However, research has not clearly defined the distinctions between them. Similarly, related constructs, such as fantasy orientation (FO), are associated with better ToM understanding; however, little is known about how FO may provide a context in which both ToM and affective empathy develop. Children between the ages of 3 and 5 (N = 82) completed a battery of ToM, empathy, and FO measures. Results demonstrated a developmental progression from ToM to affective empathy: 3‐year‐olds were likely to have neither, 4‐year‐olds were likely to have ToM only, and 5‐year‐olds were likely to have both. Additionally, results indicated that FO predicted affective empathy above and beyond ToM ability, suggesting that children whose play is high in fantasy are more practiced than their peers in sharing emotions. These findings are discussed in terms of how children's propensity toward fantasy play may contribute to their social development. 相似文献

We used a mixed-methods convergent parallel design to explore the effect of yoga on quality of life, trauma, and anxiety in low-income adults with mental illness. Participants included a convenience sample (N = 18) of parents at a community mental health agency who participated in a six-week yoga intervention. Participants completed standardized measures of quality of life, anxiety, and post-traumatic stress disorder (PTSD) pre- and post-intervention. Focus groups were conducted to further explore barriers to and the effects of participation in the yoga intervention. Wilcoxon Signed Ranks Tests indicated a statistically significant decrease in anxiety and PTSD after the yoga intervention, but no significant changes in quality of life or trait anxiety. Qualitative results reveal five themes related to participation in yoga classes, including barriers to participation and ways to improve the class. Qualitative results corroborate quantitative findings, suggesting improved relaxation and anger management for participants who strongly endorsed the benefits they experienced. 相似文献

The paper focuses on the solution business. Here we argue that the strategy can only lead a company to perform better if it encompasses a direct and positive effect on satisfaction with a supplier’s consulting capabilities. Hence we introduce the concept of consulting satisfaction, identify antecedents and analyze its consequences. To do so, we apply a mixed-methods approach. Content analysis from open interviews with company professionals yields a list of antecedents of consulting satisfaction used to devise a set of hypotheses. The latter was translated into a questionnaire based measurement instrument in order to first collect and then analyze data from a larger sample survey. Since three of the antecedents could not be supported by our study, possible explanations are presented. With our approach we tap new dimensions of solutions research. First, we inaugurate research on buying behavior within the field of solutions. Second, we stress the role of capabilities in this field and extend service–profit chain thinking. And third, we present consulting satisfaction as a lever to translate the S-D logic of marketing into more practical applications. To our knowledge this is a novel insight and can help industry decision makers better prepare for the solution business. 相似文献
