Teacher's Encouragement on Creativity,Intrinsic Motivation,and Creativity: The Mediating Role of Creative Process Engagement

Drawing on Dewey's pragmatic perspective on talent cultivation and previous research on promoting employee creativity in industry, this study investigates student creativity performance in relation to teacher's encouragement, intrinsic motivation, and creative process engagement. Based on survey data collected from 140 vocational high school students who participated in a nation‐wide contest in Taiwan, path analyses were performed using structure equation modeling techniques. The results indicate that both teacher's encouragement and intrinsic motivation have a significant, although indirect, effect on student creativity, and that creative process engagement, as opposed to teacher encouragement or intrinsic motivation, has a direct and significant mediating effect on student creativity. This finding is in partial agreement with prior research which reports student creativity is positively associated with teacher encouragement and intrinsic motivation, highlighting the mediating role of creative process engagement in facilitating student creative performance.     

Examining Effects of Self-Efficacy on Research Motivation Among Chinese University Teachers: Moderation of Leader Support and Mediation of Goal Orientations

Utilizing the Social Cognitive Career Theory (SCCT) as the theoretical framework, this study proposed a moderated mediation model investigating the complex functioning mechanisms of how self-efficacy beliefs and leader support can be related to research motivation among Chinese university teachers. A group of 310 Chinese teachers working in different universities completed an online survey. Results from structural equation modeling (SEM) analysis revealed distinct influencing paths from the predictor variables (i.e., self-efficacy and leader support) to the outcome variables (i.e., intrinsic and extrinsic research motivation). Specifically, self-efficacy beliefs predicted both mastery and performance goal orientations; mastery goal orientation, in turn, positively affected intrinsic and extrinsic research motivation. In contrast, leader support was non-significant for the both types of goal orientations, but exerted strong direct influences on the both types of research motivation. Bootstrapping methods in SEM showed that it was primarily the mastery goal orientation that mediated the relationships between self-efficacy beliefs and research motivation. Furthermore, the results from the SEM and simple slope analysis revealed that leader support moderated the association between self-efficacy and extrinsic research motivation.     

Building up resources in the relationship between work–family conflict and burnout among firefighters: moderators of guanxi and emotion regulation strategies

This study investigated the moderating effects of supervisor–subordinate “guanxi” alongside relevant emotional regulation strategies, including cognitive reappraisal and expressive suppression, undertaken by 402 firefighters experiencing burnout caused by work–family conflict, as revealed through the application and analysis of the job demands–resources model. According to the regression model for the moderating effects, high levels of supervisor–subordinate guanxi may improve the relationship between work–family conflict and burnout, while frequent suppression of expressivity may enhance this relationship. Moreover, when supervisor–subordinate guanxi is high, cognitive reappraisal may effectively mitigate the relationship between work–family conflict and burnout. To this end, both guanxi and cognitive reappraisal are crucial for supporting emotional regulation in the workplaces of ethnic Chinese societies.     

恐惧管理中死亡焦虑不同防御机制之间的关系

根据恐惧管理理论, 个体主要通过世界观、自尊和亲密关系三种防御机制来应对必死性意识引发的死亡焦虑。主流观点认为三种防御机制在防御死亡焦虑时的地位是平等的, 符合“流动补偿机制”。本文讨论了流动补偿机制的局限性, 提出三种防御机制之间关系的新观点: 优先级假设, 认为三种防御机制地位并非平等, 而是存在优先级: 亲密关系优先于世界观和自尊, 世界观优先于自尊。在梳理了支持证据后, 本文尝试从发展性视角对优先级假设提出可能的解释, 认为这种优先级来源于防御机制的发展顺序和衍生关系。     

多维项目反应理论补偿性模型参数估计:基于广义回归神经网络集合

运用广义回归神经网络(GRNN)方法对小样本多维项目反应理论(MIRT)补偿性模型的项目参数进行估计,尝试解决传统参数估计方法样本数量要求较大的问题。MIRT双参数Logistic补偿模型被设置为二级计分的二维模型。首先,模拟二维能力参数、项目参数值与考生作答矩阵。其次,把通过主成分分析得到的前两个因子在每个题目上的载荷作为区分度的初始值以及题目通过率作为难度的初始值,这两个指标的初始值作为神经网络的输入。集成100个神经网络,其输出值的均值作为MIRT的项目参数估计值。最后,设置2×2种(能力相关水平:0.3和0.7; 两种估计方法:GRNN和MCMC方法)实验处理,对GRNN和MCMC估计方法的返真性进行比较。结果表明,小样本的情况下,基于GRNN集成方法的参数估计结果优于MCMC方法。     

海马CA_3区习得性LTP的进一步探讨

分辨学习中大鼠ＰＰ－ＣＡ_３突触效应有习得性ＬＴＰ产生,进一步观察到ＭＦ－ＣＡ_３及Ｃｏｍｍ－ＣＡ_３也同步地产生习得性ＬＴＰ,表明几种输入突触都产生习得性ＬＴＰ,而ＭＦ－ＣＡ_３突触效应增强的程度则较Ｃｏｍｍ－ＣＡ_３的为大（Ｐ＜０．０１）。海马ＣＡ_３注入印防己毒素能易化ＰＰ－ＣＡ_３突触习得性ＬＴＰ的产生,工作发现一侧海马ＣＡ_３注印防己毒素,易化对侧ＭＦ－ＣＡ_３突触习得性ＬＴＰ的产生,表明两侧海马ＣＡ_３区在其习得性ＬＴＰ的形成上是相互协同的。     

乳头体对海马齿状回习得性长时程突触增强的影响

用高频电脉冲刺激大鼠乳头体（ＭＢ）,可一过性抑制由刺激穿通纤维（ＰＰ）诱发的海马齿状回（ＤＧ）群体锋电位（ＰＳ）。训练作业前先刺激ＭＢ,导致ＤＧ的习得性长时程突触增强（ＬＤＬＴＰ）的形成显著延缓,相应地延缓了条件性饮水反应的建立。电刺激ＭＢ对ＰＰ─ＤＧＰＳ的这种抑制作用在训练所产生的ＰＳ增大达最高水平时显著减弱,刺激ＭＢ对ＬＤＬＴＰ的保持及相应地对条件反应的巩固没有明显影响。结果表明ＭＢ对ＤＧＬＤＬＴＰ的形成有抑制性调制作用。
