Longitudinal relations between behavioral inhibition and social information processing: Moderating role of maternal supportive reactions to children's emotions

Utilizing multiple measures of interpretive biases, the current study examined the roles of toddlers’ behavioral inhibition (BI) and maternal supportive reactions to children's negative emotions in relation to children's interpretive biases across middle to late childhood. Toddlers’ BI was measured during several laboratory tasks (n = 248) at 2 and 3 years of age. Mothers reported on their reactions to children's negative emotional expressions when children were 7 years old (n = 203), and children's interpretations of social cues were assessed at 7 and 10 years of age (n s = 179 and 161, respectively). Toddlers with high levels of BI expressed less positivity toward social engagement with unfamiliar peers during discussion of ambiguous social situations. Further, children with high BI were less likely to attribute the cause of negative social situations to external factors, particularly when mothers were less accepting of children's negative emotional displays. Findings are discussed in terms of cognition related to the interpretation of ambiguous and threat‐related social situations among temperamentally at‐risk children.     

Visibly ageing femininities: women’s visual discourses of being over-40 and over-50 on Instagram

Abstract

This article explores visual discourses about over-40 and over-50 femininities that emerge from women’s own Instagram accounts. It analyses women’s visual and textual rhetoric of what over-40 and over-50 looks like, and whether it could interrupt the ageist, sexist, and body-normative discourses of female ageing and visibility. Intertextual visual discourse analysis of images, captions, and hashtags reveals two dominant themes (fitness and fashion) and two repeating rhetorical elements (motherhood and self-sufficiency) through which women make themselves visible as over-40/50. A few explicitly subversive discourses (i.e., over-40 fatshion account) exist, but a discourse of a healthy, fit, fashionable, independent, self-sufficient, and happy mother over-40/50 is prevalent. It easily lends itself to being interpreted as an insidious reproduction of post-feminist ideology, but I argue that there are moments of critique and subversion within. Thus, a reparative reading that acknowledges moments of disconnect from the discourse that normalizes ageing women’s limited or non-existent visibility is offered.

新媒体时代大学生社会主义核心价值体系教育的原则

大学生社会主义核心价值体系教育是当前大学生思想政治教育工作的核心内容。进入新媒体时代,大学生社会主义核心价值体系教育应深入把握新媒体的特性,遵循主导性与多样性相结合、虚拟性和现实性相结合、理论性和实践性相结合、继承性和创新性相结合的教育原则,不断提高教育实效性,促进大学生将社会主义核心价值体系转化为自觉追求。     

冯铿寻求女性解放道路的心路历程

潮籍革命女作家冯铿的创作始终贯穿着一条关注女性命运、寻求女性解放道路的主线。冯铿的作品序列展示了她寻求女性解放道路的心路历程,从早期强烈呼吁社会为正在遭受苦难的女性"快谋救护的法子",到批判像"一团肉"似的所谓的"时代女性",指明女性"最后的出路"是参加革命,认为真正的新女性是"把自己是女人这一回事忘掉干净"的革命女性。     

社会网络、 先前经验与创业风险识别

无法识别创业风险是导致创业失败的主要原因之一,如何有效识别并管理创业风险是新创企业健康成长的关键.社会网络能够弥补创业者在识别风险过程中的信息劣势,但既有研究极少探索社会网络是否以及如何影响创业风险识别.为弥补这个研究空白,文章利用信息处理理论为研究框架,构建了创业风险识别模型.具体而言,结构洞和网络强度有利于创业者获取更多、高质量与风险相关的信息,进而识别更多的创业风险;获取信息的数量在网络强度与创业风险识别关系之间发挥完全中介作用;创业者的先前经验正向影响创业风险识别,并对结构洞与获取信息的数量之间关系起调节作用.文章讨论了研究结果的理论贡献与实践启发.     

伊拉克战争与公众参与中国中东外交政策制定

伊拉克战争为公众参与中国中东外交政策制定提供了机会,参与群体前所未有地扩大,参与途径全面拓展,不同意见的表达开始涌现,公众主动对外交建言献策,开始有意施加民意压力。更为重要的是,公众意见开始成为外交部门对外传播国家主张的背景支撑和参考因素。公众因素开始成为中国制定中东外交决策时需要考虑的重要参数之一,但其影响力有限,更多是参考和制约作用,其影响正处于发展之中。     

Smooth tail-index estimation

The two parametric distribution functions appearing in the extreme-value theory – the generalized extreme-value distribution and the generalized Pareto distribution – have log-concave densities if the extreme-value index γ∈[?1, 0]. Replacing the order statistics in tail-index estimators by their corresponding quantiles from the distribution function that is based on the estimated log-concave density ? f _n leads to novel smooth quantile and tail-index estimators. These new estimators aim at estimating the tail index especially in small samples. Acting as a smoother of the empirical distribution function, the log-concave distribution function estimator reduces estimation variability to a much greater extent than it introduces bias. As a consequence, Monte Carlo simulations demonstrate that the smoothed version of the estimators are well superior to their non-smoothed counterparts, in terms of mean-squared error.
