Does parental job insecurity matter? Money anxiety, money motives, and work motivation

A structural model focusing on the spillover effect of parental perceived job insecurity on money anxiety was developed and tested. The crossover effect of parents' money anxiety on their children's money anxiety, money motives, and motivation to work was also examined. Data were collected from a sample of undergraduates and their parents. Results of structural equation modeling analyses supported a spillover effect of paternal perceived job insecurity on paternal money anxiety. However, maternal perceived job insecurity was not significantly associated with maternal money anxiety. Results also supported a crossover effect of parental money anxiety on youths' money anxiety. Youths' money anxiety was significantly related to youths' negative money motives. In turn, youths' negative money motives were associated with their intrinsic motivation to work. Implications of the findings are discussed.     

小学三～五年级儿童创造性思维训练的实验研究

研究表明学龄儿童已具有一定的创造力 ,因此要重视并激发儿童的创造活动。本研究在前人研究的基础上 ,自编了一套创造性思维训练题 ,并设计了传统讲授教学法和促进、诱导学生自我发现的发现法二种训练方法 ,同时与未经训练的对照组比较 ,考察了小学三～五年级儿童创造性思维的几个维度和总体水平上在训练前后的变化。结果表明 :经过一个学期的短期训练 ,无论在创造性思维的不同维度上还是在总体水平上 ,都对小学儿童产生了显著的影响 ,而所设计的二种训练方法在短期效果上没有明显差异。

Chinese students' attitudes towards US universities in the US–China conflict

Globalization has been the catalyst of world economic development in the past decades. However, the phenomenon has recently been severely challenged by a wave of deglobalization. Within this new trend, the conflict between the United States (US) and China has attracted the attention of scholars from various fields because of the two countries' significance in the world economy. In this study, we focus on the higher education sector, which is highly relevant to globalization, and explore the factors that may affect Chinese college students' attitudes towards US universities, including country image, cultural openness, consumer animosity and perceived quality. In particular, we distinguish between cognitive and affective animosity and test their different impacts on students' attitudes. The results show that students' perception of the US's image positively influences attitudes towards the country's universities thanks to the mediation of perceived quality. Moreover, cultural openness and cognitive animosity are positively related to attitudes, whereas affective animosity exerts a negative impact on attitudes. The implications and limitations of this study are also discussed.     

高二理科生物理问题创造性解决的表象特征研究

物理问题创造性解决是一个发散思维和聚合思维交替运行的过程,而表象对问题的创造性解决具有重要作用。本研究通过自编的物理问题对天津市某中学109名高二理科学生进行物理问题创造性解决测验,探讨高中理科学生物理问题创造性解决中的表象特征。验证了表象与物理问题创造性解决中的发散思维具有显著的正相关,与聚合思维无显著相关。对109名高二理科学生K聚类分析发现：物理问题解决过程中,高创造性和中等程度创造性的学生人数较少,而低创造性的学生人数较多;表象丰富性很高和较高的学生较少,表象丰富性较低的学生较多。     

《文心雕龙》易学撰著体例探析

就<文心雕龙>撰著体例而言,刘勰依据汉易象数原则及马融对大衍之数的解释,原本只将全书定为五十章并分为上下两篇;依汉易对太极及三才说的解释,由<原道>、<征圣>、<宗经>三篇构成总论,<原道>则相当于其一不用的太极.由<辨骚>至<书记>为上篇文体论,依取象原则,旨在论文体渊源与流变;下篇旨在论问数,而<神思>至<总术>又是集中阐述驭文之术;上篇<原道>以下及下篇<神思>以下各篇篇第次序都是依取两两相偶的解易体例排定的,故<文心雕龙>通行本各篇篇第次序当为原貌.依象数不离及八宫卦原则,上篇与下篇又存在着对应关系.总之,刘勰<文心雕龙>的撰著体例是依取汉易象数学的解易体例而确立的.     

幽门螺杆菌cagA基因多态性对临床结局的影响:东亚菌株和西方菌株

CagA蛋白是幽门螺杆菌最重要的毒力因子之一.目前已证实cagA基因存在东亚及西方两种亚型.幽门螺杆菌产生CagA蛋白,注入胃上皮细胞后在其羧基端EPIYA重复序列区进行酪氨酸磷酸化,进而与SHP-2酪氨酸磷酸化酶相互作用,参与上皮细胞的信号传导,导致细胞骨架结构的重排,引起细胞表面形状的改变和细胞动力的增强,造成细胞异常的增殖和运动,在胃癌的发生中起了主要作用.cagA基因的羧基端EPIYA重复序列被认为是区分东亚型和西方型菌株的分子标记,东亚型CagA与SHP-2亲和力大于西方型,最终影响着不同CagA+菌株感染的临床表现.     

有限理性的"占优启发式"和"齐当别"决策模型的作为——当Allais悖论杠杆撬动了期望效用理论

人们在做决策时常常要受到时间或知识的限制,有时还要受到其双重限制。关于人们是如何进行风险决策,早期有期望效用理论对其加以解释,但Allais悖论对其标准化地位提出了挑战。Simon的“有限理性”观点提出后,一些研究者开始致力于开发决策的“有限理性”模型。文章讨论并比较了无限理性的期望效用理论被Allais悖论杠杆撬动之后,有限理性的“占优启发式”和“齐当别”决策模型所能做的和所不能做的。两种模型的决策标准、计算策略以及未来研究的展望也一并作了讨论。     

儿童认知发展水平诊断工具IPDT的动态化编制及其在低社会经济地位儿童中的应用

“皮亚杰认知发展量表” (IPDT)中的守恒与关系领域经动态化改编后已被证实适用于小学低年级儿童的潜能评估。在此基础上, 本研究旨在构建适用于小学高年级儿童的IPDT表征、分类、规律领域的动态测验; 并运用所构建的IPDT动态测验对低社会经济地位(SES)儿童进行认知潜能评估; 而后经过对低SES儿童的推理认知干预, 进一步考查认知干预在低SES不同潜能儿童的认知能力和数学成就中的促进作用。结果发现：(1)改编的IPDT表征、分类、规律领域的动态测验包含“前测—干预—迁移—后测”4个阶段, 所构建的逐级提示干预方案合理适切, 可以有效区分不同认知潜能水平的小学高年级儿童, 特别是弱势儿童; (2)推理认知干预对由IPDT动态测验细致区分出的不同潜能水平的低SES儿童作用不同, 尽管他们在认知能力与数学成就上均有进步, 但低SES高潜能儿童比低SES低潜能儿童从干预中获益更多。     

跨期决策中的偏好反转：突出性效应和兼容性效应

风险决策中的偏好反转现象可以用突出性效应和兼容性效应来解释,本研究考察这两种效应是否同样适用于解释跨期决策中的偏好反转现象。采用鼠标追踪范式,考察跨期决策中的选择与出价过程,结果发现：（1）在选择任务中,个体对时间属性的关注比例显著高于出价任务;（2）在出价任务中,个体对金钱属性的关注比例显著高于选择任务。该结果表明跨期决策偏好反转现象中同样可以用突出性效应与兼容性效应来解释。
