Purple sweet potato color repairs d-galactose-induced spatial learning and memory impairment by regulating the expression of synaptic proteins

Purple sweet potato color (PSPC), a class of naturally occurring anthocyanins used to color food (E163), has been reported to possess a variety of biological activities, including anti-oxidant, anti-tumor, and anti-inflammatory. The effect of PSPC on the spatial learning and memory of mice treated with d-galactose (d-gal) was evaluated by the Morris water maze; d-gal-treated mice had decreased performance compared with mice in the vehicle and PSPC groups, while the PSPC + d-gal group showed significantly shortened escape latency to platform, increased swimming speed, more target quadrant search time and more platform crossings as compared with the d-gal group. Brain functions, such as memory formation and recovery of function after injury, depend on proper regulation of the expression levels of the pre- and post-synaptic proteins. We investigated the expression of four pre-synaptic proteins (growth-associated protein-43, synapsin-I, synaptophysin, and synaptotagmin) and two post-synaptic proteins (post-synaptic density protein-95 and Ca²⁺/calmodulin-dependent protein kinase II) in the hippocampus and cerebral cortex, respectively, in response to different treatments. Western blotting analysis showed that there were significant decreases in the expression of these representative synaptic proteins in the hippocampus and cerebral cortex of d-gal-treated mice. Interestingly, these decreased expression levels of synaptic proteins could be reversed by PSPC. The levels of expression of these representative synaptic proteins in mice treated with PSPC alone were not significantly different from those in untreated mice. The results of this study suggested that memory impairment and synaptic protein loss in d-gal-treated mice may be improved by treatment with PSPC.     

Translating External Knowledge to Team Creativity in Turbulent Environments: The Role of Absorptive Capacity and Knowledge Integration

In seeking to understand factors contributing to team creativity in dynamic environments, we explored the role of external knowledge search on team creativity through absorptive capacity and knowledge integration. We tested our hypotheses with a sample of 96 teams involving 421 employees in China. Results demonstrated that external knowledge search related positively to team creativity, fully mediated by both absorptive capacity and knowledge integration. In addition, environmental dynamism played a moderating role in the relation between external knowledge search and absorptive capacity, as well as in the relation between external knowledge search and knowledge integration. We discussed the implications of these findings for research and practice.     

儿童数学应用题表征水平的特点研究

本研究运用实验法对某普通小学的161名4～6年级学生进行了长方形面积任务和MPI测验,以考察学生的应用题表征水平及其对问题解决的影响.结果表明:(1)表征水平随着年级的升高而不断提高,学生在表征水平上性别差异不显著;(2)无论哪个年级.表征水平都是优等生好于中等生,中等生好于差等生;表征水平越高,学生在问题解决上的成绩越好;(3)随着题目难度的不断加大,各表征水平的学生在解题正确率上的差距也在不断拉大.也就是说,题目越难,表征水平在解题中的作用也就越明显.

听障学生与正常学生社会认知能力的比较研究

以配对比较的方法,通过观点采择、个性特征认知、故事复述等社会认知能力测验,考察听障学生与正常学生的社会认知能力的差异,结果表明:(1)在智力、年龄相同的情况下,听障学生的社会认知能力发展明显比正常学生迟缓;(2)听障学生与正常学生的社会认知能力不存在性别差异;(3)听障学生社会认知发展迟缓与其社会互动经验的缺乏有关联。     

走向深层发展伦理学——贝克风险社会理论的发展伦理学意蕴

对发展伦理学而言,贝克“风险社会理论”的根本方法论意义,在于启发我们思考这样一个问题:“应该用什么方法、在什么层面上建构发展伦理学”?贝克风险社会理论对明确发展伦理学的研究视域、学理层次、研究平台等具有重要方法论启示。     

大学生社会行为、成就动机与网络成瘾倾向的关系研究——以武汉市5所高校为例

运用问卷调查法探讨大学生的社会行为、成就动机与网络成瘾倾向的关系。对299位大学生的调查结果表明:(1)追求成功动机、避免失败动机和社交能力对大学生网络成瘾倾向有直接影响;(2)成就动机还通过社交能力间接影响网络成瘾倾向。     

道德法律化的途径、方式和表现形态

法律中包含了伦理性内容和技术性内容,从内容上看,绝大多数法律都有着伦理道德的基础.道德法律化是立法中的普遍现象,它经历了从伦理、物理再到法理,最后成为法律的过程.道德法律化的具体方式包括道德向法律的直接转化和间接转化,法律最后拥有了技术性和国家强制性的特征.从道德法律化的表现形态上看,它包括道德义务的法律化和道德权利的法律化,以及道德的公法化和道德的私法化.在道德法律化的过程中,道德直接或间接地构成了法律的价值基础,演变成一种制度性的伦理形态,并对人类生活产生深远影响.     

A clean self can render harsh moral judgment

Physical cleanliness has many medical benefits, such as protection from the dangers of contagion. We explore a potential unintended consequence of cleanliness. Given the metaphorical association between physical cleanliness and moral purity (Zhong & Liljenquist, 2006), we contend that a clean self may also be linked to a virtuous self. This enhanced moral self-perception can in turn license harsher moral judgment. Three experiments found that cleanliness, whether induced via physical cleansing or through a visualization task, licensed severe judgment on morally contested issues such as abortion and pornography. Further, we found that an inflated moral self mediated the relationship between cleanliness and moral judgment. These results provide unique insight to the social significance of cleanliness and may have important implications for discrimination and prejudice.     

Exploring the Effect of Perceived Teacher Support on Multiple Creativity Tasks: Based on the Expectancy–Value Model of Achievement Motivation

The present study explores the effect of perceived teacher support on three forms of thinking related to creativity. Tests of convergent thinking (by means of the Remote Associates Test), insight thinking (explored through a brain‐teaser test), and divergent thinking (by means of a verbal creativity test) were given to 512 middle school students in China, along with assessments of their perceived teacher support and creative self‐efficacy. The results of this study indicate that perceived teacher support positively predicts convergent thinking and insight thinking, with creative self‐efficacy playing a partial mediating role between perceived teacher support and convergent thinking. However, no significant relationships were found between perceived teacher support and divergent thinking. The findings partly lend support to the expectancy–value model of achievement motivation that teacher’s behavior influences student performance through self‐belief pathway.
