疼痛和不公正知觉的相互关系

结合认知神经科学的研究成果,梳理了疼痛和不公正知觉之间的关系,以及两者之间的中介变量和调节变量,并提出了可能的干预方案。疼痛和不公正知觉之间存在互为因果的关系。疼痛可以加剧个体的不公正知觉,不公正知觉被激活后,也会加剧个体的疼痛感,从而形成一个恶性循环。其中,情绪在两者之间起中介作用。此外,公正世界信念和医患关系可以调节两者之间的关系,医患关系还可以与情绪相互作用,再影响不公正知觉。所以,可对疼痛患者的情绪、信念以及与医护人员的关系进行干预,从而促进疗效,提高患者的生活质量。     

被动性社交网站使用与错失焦虑症：压力知觉的中介与乐观的调节

本研究为考察被动性社交网站使用对移动社交媒体环境下大学生错失焦虑症的预测,以及压力知觉的中介作用、乐观的调节作用与性别差异,选取443名大学生进行问卷调查。结果表明：（1）被动性社交网站使用通过直接预测与压力知觉的中介作效应两种方式作用于错失焦虑症;（2）乐观调节中介模型的直接路径,在低乐观水平下,被动性社交网站使用对错失焦虑症的预测作用显著;在高乐观水平下,该预测作用不显著;（3）中介效应与调节效应存在性别差异：在女生群体中,压力知觉的中介效应大于男生群体;而乐观的调节效应仅存在于男生群体中。     

道德信仰的发生机制

道德信仰的发生机制至少包括三个方面 ,即 :需要的体认机制 ;伦理义务的内化机制 ;道德心理的整合机制。需要的体认机制涉及到对人性、人生的价值、人的使命等问题 ,它是道德信仰形成的主体基础 ;伦理义务的内化机制涉及到人的社会伦理关系、社会规定性和制约性、社会价值、社会道德规范及其教化等问题 ,它是道德信仰形成的客观条件 ;道德心理的整合机制涉及到道德认知、道德情感、道德意志和道德人格等问题 ,它是道德信仰形成的主、客观方面的动态的统一。     

网络游戏成瘾与海洛因成瘾存在相同的神经机制吗?——基于MRI的证据

网游成瘾与海洛因成瘾具有许多相似的临床表现,但其神经机制是否相同还不得而知。综合近5年来的MRI研究发现,两类成瘾存在部分相同区域的脑结构和功能损害,且在成瘾线索诱发下二者的4个成瘾相关环路(认知控制环路、奖赏环路、动机环路和记忆-学习环路)均出现了广泛而增强的脑区激活反应。但海洛因成瘾的脑损害区域偏向更高级的认知控制环路和奖赏环路,损害范围也更广(4个环路的功能连通性均降低),而网游成瘾的脑损害主要发生在相对低级的记忆-学习环路和动机环路,损害范围也较窄(功能连通性降低只发生在认知控制和记忆-学习环路之间)。这些结果说明,两类成瘾行为的神经机制既有相同点,又有差异性。     

Accounting for Missing Correlation Coefficients in Fixed-Effects MASEM

Meta-analytic structural equation modeling (MASEM) is increasingly applied to advance theories by synthesizing existing findings. MASEM essentially consists of two stages. In Stage 1, a pooled correlation matrix is estimated based on the reported correlation coefficients in the individual studies. In Stage 2, a structural model (such as a path model) is fitted to explain the pooled correlations. Frequently, the individual studies do not provide all the correlation coefficients between the research variables. In this study, we modify the currently optimal MASEM-method to deal with missing correlation coefficients, and compare its performance with existing methods. This study is the first to evaluate the performance of fixed-effects MASEM methods under different levels of missing correlation coefficients. We found that the often used univariate methods performed very poorly, while the multivariate methods performed well overall.     

The Solubility of Salt: A Divine Action Account

In the burgeoning literature on dispositions, solubility is a standard example. In this paper we give a rigorous theistic divine action account of the simple mechanism of the dissolving of salt, NaCl, into the ions Na⁺ and Cl^?. We explore this reaction in terms of an alternative view of divine action, Divine Compositionalism, which holds that the functioning of every physical, chemical, and biological mechanism in the universe is a manifesting complex disposition, which is nothing other than ways God acts according to plan.     

非工作时间使用通信技术处理工作的“双刃剑”效应及心理机制

在当前的互联网时代下,个体“在非工作时间使用通信技术处理工作”的现象已经非常普遍,并因其对个体日常工作生活适应可能产生的深远影响而受到研究者的广泛关注。基于对该领域已有研究文献的全面回顾,本文着重探讨了非工作时间使用通信工具处理对个体工作生活适应的“双刃剑”效应及效应发生的心理机制,并对该领域未来的研究方向进行了针对性的展望。

Organisational interventions to improve employees' health and wellbeing: A realist synthesis

Although organisational interventions have shown promising results in improving employees' health and wellbeing, reviews of the effectiveness of such interventions conclude results are inconsistent. Realist synthesis is considered an appropriate method of literature review to improve the consistency of empirical evidence by developing generalisable statements of ‘what works for whom in which circumstances’. In this article, to identify and synthesise existing evidence from the empirical studies of organisational interventions, we conducted a realist synthesis according to the RAMESES publication standards. We reviewed 28 articles. Six realist programme theories were developed that explain how different mechanisms of organisational interventions may bring about different outcomes in different contexts. These realist programme theories are based on the process mechanisms of implementation adherence, communication, employees' participation, senior management support, middle management support and external consultants/researchers support. This realist synthesis enhances the understanding of how organisational interventions may improve employees' health and wellbeing, in which contexts, and for which group of employees. As such, it makes an important potential contribution to designing, implementing and evaluating future organisational interventions.     

雌激素替代疗法的利与弊

随着妇女社会地位的提高,以及人们对健康与生活质量要求的提高,绝经后雌激素替代疗法(HRT)日益成为人们关注的话题,越来越多的妇女选择在进入围绝经期后开始接受HRT,以改善因内源性雌激素分泌不足而引起的种种不适,确实提高了生活质量.但是,这种方法有增加子宫内膜癌、乳腺癌等其他疾病发病率的潜在危险,于是我们在临床应用时应该用辨证的眼光去看待它,试图抓住其主要矛盾,尽可能扬其利,避其害,以达到安全而有效地提高广大中老年妇女生活质量的目的.
