How do Mandarin speakers conceptualize time? Beyond the horizontal and vertical dimensions

Cognitive Processing - Mandarin speakers, similar to speakers of most other languages around the world, tend to conceptualize time in terms of space. However, it has been supposed that Mandarin...     

付出回报失衡与高校青年教师的焦虑：心理契约破裂的中介作用和过度承诺的调节作用

基于付出回报失衡模型,考察了高校青年教师的付出回报失衡与焦虑的关系。对336名高校青年教师进行了多时间点调查。结果显示：（1）付出回报失衡对高校青年教师的焦虑有显著正向预测作用;（2）付出回报失衡通过心理契约破裂间接影响高校青年教师的焦虑;（3）相较于低过度承诺教师,高过度承诺教师的付出回报失衡经由心理契约破裂对焦虑的影响更为突出。研究结果揭示了付出回报失衡对焦虑影响的过程机制和边界条件,对高校青年教师工作焦虑的改善有一定启示。     

幼儿在联合行动中共同表征能力的发展

为探究幼儿联合行动共同表征能力的发展,实验1通过比较186名3~5岁幼儿在相同任务和不同任务的表现,发现4岁和5岁幼儿在不同任务中的表现比相同任务差;实验2进一步验证幼儿在不同任务中较差的表现源于对自我和同伴的共同表征。结论：3岁幼儿无法在联合任务中同时表征自我和同伴,没有表现出明显的共同表征能力,4岁以上幼儿开始具备稳定的共同表征能力,能够在联合任务中同时表征自己和同伴,由此对自己的行为表现造成干扰。     

儿童期虐待与青少年网络欺负行为的关系：自尊的中介作用和友谊质量的调节作用

本研究采用问卷法对2407名青少年进行调查,探究儿童期虐待对青少年网络欺负行为的影响,以及自尊的中介作用和友谊质量的调节作用。结果表明：（1）儿童期虐待显著正向预测青少年网络欺负行为。（2）自尊在儿童期虐待与青少年网络欺负行为之间起部分中介作用。（3）儿童期虐待对青少年网络欺负行为的间接效应的前半段路径受到友谊质量的调节。友谊质量高、低水平下儿童期虐待对自尊的预测作用均显著,但友谊质量较高的青少年群体中儿童期虐待对自尊的预测作用更强。     

同伴特点如何影响人们的合作与冲突行为?

人类的生存繁衍依赖于人们之间的相互合作,合作与冲突行为的研究近年来成为心理学的研究热点。本研究通过实验程序操纵Chicken Game中博弈同伴的特点,考察个体在社会困境中面对不同特点同伴时的合作行为。结果发现：(1)同伴道义论组和功利论组总和解率没有显著差异,同伴竞争组和合作组的总和解率也没有显著差异。(2)在与道义论以及合作型的同伴互动时,个体的行为没有明显受到上次博弈反馈的影响。(3)当同伴为功利论时,相比于上次博弈个体选择和解而同伴选择进攻,双方都选择和解时个体在当前博弈中更倾向于和解;(4)在同伴竞争组中,相比于上次博弈个体选择进攻而同伴选择和解,双方都选择和解时被试在当前博弈中会更倾向于和解。实验结果表明个体在博弈任务中会受到同伴特点的影响,并且同伴在博弈中的行为特点的影响更为显著。本研究从同伴特点来考察个体的合作行为,揭示了影响个体博弈行为的一种因素。     

Active school travel is associated with fewer suicide attempts among adolescents from low-and middle-income countries

Background/Objective: This study explored the association between active school travel (AST) and suicide attempts among adolescents in low- and middle-income countries (LMICs). Method: We used the data from the Global School-based Health Survey, including 127,097 adolescents aged 13-17 years from 34 LMICs. A self-reported survey was used to collect data on AST and suicide attempts as well as some variables. Multivariable logistic regression was performed to assess the association between AST and suicide attempts. A meta-analysis with random effects was undertaken to identify the difference in the association between AST and suicide attempts. Results: Across all the adolescents, the prevalence of AST was 37% and the prevalence of suicide attempts was 11.60%. Adolescents who engaged in AST were less likely to have suicide attempts irrespective of gender. The country-wise analysis indicated a large inconsistency in the association between AST and suicide attempt across the countries. Conclusions: AST would appear to be a protective factor for reducing suicide attempts among adolescents. However, the association between AST and suicide attempts varied greatly across the countries. Future studies should confirm the association between AST and suicide attempts.     

北朝临淄崔氏家族史新证

本文比照文献资料,对北朝临淄崔氏家族墓志所载崔鸿八世祖崔岳仕宦情况进行了考证,指出墓志所载崔岳“晋司徒”属于伪托。实际情况是:西晋时崔岳为朝鲜令,庇护匈奴刘曜而被追赠为前赵“大司徒”,由于十六国北朝时期匈奴与汉民族矛盾尖锐,在当时正统观念支配下,崔氏墓志及《十六国春秋》无不避讳此事。

A multi-objective mathematical programming problem with fuzzy relation constraints

In this study we discuss the problem of multi-objective mathematical programming with constraints defined by ‘max-min’ composite fuzzy relation equations. Since the feasible region is normally non-convex, the properties of the efficient points of a non-convex feasible region under multi-objectives are investigated and illustrated by examples. The necessary and sufficient conditions are proposed and proved. To facilitate decisions, a procedure that transforms these efficient points of an interval-valued decision space into a constant-valued decision space is proposed when the level of confidence is given by a decision maker. Then the transformed problem becomes a multi-attribute decision problem that can be evaluated by Yager's method to find the optimal alternative.
