Disentangling the Relations Between Different Components of Family Socioeconomic Status and Chinese Preschoolers’ School Readiness

Family socioeconomic status (SES) has been frequently linked to children’s early development. Treating SES as an aggregated variable has many issues, as different components of SES may relate to child outcomes through divergent mechanisms. The purpose of the study was to examine whether parents’ engagement in home learning activities and children’s participation in extracurricular activities (EAs) would function as pathways through which individual SES components related to children’s school readiness. A total of 588 families with preschool‐aged children were recruited from Guangdong province in China. Children’s receptive vocabulary, Chinese reading, and early math skills were individually assessed at three time points, and children’s social skills were rated by parents. Parents reported their engagement in home learning activities with children and their children’s participation in EAs. The results showed that all three components of family SES were related to multiple aspects of children’s school readiness, but through different pathways. Parental income was related to children’s school readiness through EA participation only; parental education and occupational status were associated with school readiness via both parental engagement and child EA participation. The findings suggest that considering SES components separately will produce a more nuanced understanding of the divergent pathways through which family SES may relate to children’s school readiness. Chinese government may provide parent education programs focused on cognitive stimulation for low‐SES families to promote children’s school readiness. Furthermore, the government needs to ensure children’s equal access to EAs to prevent increasing the developmental gap among children from discrepant socioeconomic backgrounds.

智慧的特质论与状态论：分歧、统整与新解

特质论与状态论之争是智慧研究领域新兴的热门话题。特质论认为智慧是稳定且不易干预的人格特质;状态论认为智慧是一种相对容易波动的心智状态,短期内可以改变且容易受外在情境的影响。基于人格心理学研究的“密度分布说”则为特质论与状态论之争提供了系统的整合模型。受此启发,本研究在以往理论的基础上提出“特质-状态正态分布假说”,旨在进一步补充完善“密度分布说”并为特质论与状态论研究提供新的理论视角。未来研究仍需结合多种智慧测量手段,加强纵向追踪研究,探索智慧本质观与密度分布说的关系,开展相应的跨文化研究。     

Popularity Procurement and Pay Off: Antecedents and Consequences of Popularity in the Workplace

Purpose

This study examines agreeableness and work knowledge as predictors of employees’ popularity above and beyond core self-evaluation (CSE), and the moderating role of these constructs on the CSE–popularity relationship. We also investigate popularity’s effects on supervisor-rated task performance and promotion potential, and the conditional indirect effects of CSE on these outcomes via popularity.

Design/Methodology/Approach

Multi-source data were collected from 213 employees, their coworkers, and direct supervisors in a Chinese mine trading company.

Findings

Agreeableness predicted popularity above and beyond CSE and moderated the CSE–popularity relationship, although the direct and moderating effects of work knowledge were nonsignificant. Popularity positively influenced performance ratings but not promotion potential. Results also supported conditional indirect effects of CSE on performance ratings via popularity.

Implications

The current findings underscore the importance of examining workplace popularity. Discovering agreeableness as an additional predictor of popularity and its moderation effects on the CSE–popularity link suggests that communal qualities are important for employees’ attainment of popularity. The discussion also focuses on expanding the scope of workplace popularity to include performance-related outcomes. Lastly, this study considers how employee characteristics connect to performance ratings through popularity.

Originality/Value

Workplace popularity is relatively unexplored but has tremendous organizational implications. This research advances the understanding of how to attain workplace popularity and the boundary conditions for the relationship between CSE and popularity. It also extends consequences associated with workplace popularity beyond interpersonal outcomes and assesses the role of popularity, a construct rooted in collective perception, in explaining links between employee characteristics and performance-related outcomes.

     

群体决策过程中的信息取样偏差

一般认为,决策群体的优势是能综合各个成员拥有的不完整信息,形成对所有决策备择方案的无偏差的认识,从而作出最佳选择。但“群体讨论中的有偏差信息取样模型’认为,群体在决策中往往表现出倾向于讨论两种信息：(1)各成员讨论前都拥有的信息;(2)支持成员在讨论前所偏好的信息。该实验通过模拟人员选拔决策形式的实验室实验,对这一模型的假设进行验证。研究结果表明,大多数群体选择了一开始受到大多数成员支持的候选人,而非实际的最佳人选;群体讨论非但未纠正,反而加强了成员对候选人原有的歪曲印象。     

神经细胞粘附分子的唾液酸化作用对小鸡记忆的影响

神经细胞粘附分子的多聚唾液酸化不仅影响发育阶段神经元之间的相互作用,而且在学习记忆过程中也起着重要的作用。实验中的特异切割神经细胞粘附分子和多聚唾液酸之间α－２,８键在内神经氨酸苷酶ｅｎｄｏｎｅｕｒａｍｉｎｉｄａｓｅ ＮＥ定位注射到一日龄小鸡脑ＩＭＨＶ内,此酶明显破坏小鸡对一次性被动回避反应的记忆保持。这种破坏作用与酶的剂量有关,小于４μｇ的内神经氨酸苷酶对小鸡的记忆没有明显的影响。对胚胎第２０天     

社会运行、社会秩序与王朝的治乱盛衰——中国社会思想史研究的新视野

社会运行理论与中国社会思想史研究具有内在的同一关系,为了有效达成"了解过去,解释现在"的宗旨,中国社会思想史研究必须立足当下现实,并回归传统情境.不可以现成的、先验的尺度在资料文献中辨认寻绎社会思想,而应运用社会运行论的知识框架与理论范式,综合考量某个社会精英或学术流派的思想学说和行动主张,逻辑呈现他们如何以社会秩序为中心,从不同角度、不同层面回应社会问题和社会矛盾.进而展开去乱求治的理性思考与实践.

该文通过2个实验研究旨在探究将演绎推理和类比推理结合在一起的四卡条件推理的类比转换运用的特点。结果表明：1）假设检验的条件推理过程在特定的实验条件下,表现出推理过程转换的心理加工特点;2）改善问题的陈述形式,使之和样例问题一样,能够降低推理过程转换的难度,促进推理过程转换的成绩;3）2个样例归纳的图式促进同形问题的解答,却对推理转换过程有抑制作用。
