日记式追踪研究高校教师职业枯竭的产生原因及内部关系 总被引:1,自引:0,他引:1
该研究针对职业枯竭研究领域存在争议的两大理论问题——产生机制与内部过程,使用日记研究方法对重点高校教师进行了追踪调查。得到以下结果:1)在枯竭的成因部分:压力感、付出-回报的不平衡对耗竭存在显著正向的预测作用,且不平衡还是压力感与耗竭之间的部分中介变量。此外,二者还可完全通过耗竭作用于讥诮维度。自足资源对耗竭和讥诮均无显著影响,它只对职业效能有显著的正向预测作用,且是职业效能的唯一前因变量。2)在枯竭三维度的内部关系部分:耗竭与讥诮存在显著的正向联系,且解释风格在其中起到调节作用,即越将负性事件归因于外部环境或他人,耗竭对讥诮的正向预期作用就越强。而职业效能维度显示出与耗竭及讥诮相分离的态势,与后二者均无显著的相关关系。 相似文献

一风险社会的技术本质我们的时代是一个技术时代,科学技术无孔不入地渗透到我们生活的各个方面。我们该如何认识当今社会?这是现代社会理论家和思想家们最关心的问题。由当代社会理论家和思想家贝克、吉登斯等提出的“风险社会”概念可以说是现代社会的一个典型特性。所谓“风险社会”是指在全球化发展背景下,由人类实践所导致的全球性风险占据主导地位的社会发展阶段,在这样的社会里,各种全球性风险严重威胁整个人类的生存和发展。进入工业社会以后,人类对于诸如核泄漏、生化武器、公共卫生事件、恐怖主义以及现代高新技术的盲目发展可能带… 相似文献

We present an implemented approach for domain-restricted question answering from structured knowledge sources, based on robust semantic analysis in a hybrid NLP system architecture. We perform question interpretation and answer extraction in an architecture that builds on a lexical-conceptual structure for question interpretation, which is interfaced with domain-specific concepts and properties in a structured knowledge base. Question interpretation involves a limited amount of domain-specific inferences, and accounts for higher-level quantificational questions. Question interpretation and answer extraction are modular components that interact in clearly defined ways. We derive so-called proto queries from the linguistic representations, which provide partial constraints for answer extraction from the underlying knowledge sources. The search queries we construct from proto queries effectively compute minimal spanning trees from the underlying knowledge sources. Our approach naturally extends to multilingual question answering, and has been developed as a prototype system for two application domains: the domain of Nobel prize winners, and the domain of Language Technology, on the basis of the large ontology underlying the information portal LT World. 相似文献

Depression, anxiety and posttraumatic stress disorder (PTSD) are common complications of cerebrovascular diseases. However, they were seldom explored in Moyamoya Disease (MMD) survivors. In this study, we measured the prevalence of depression, anxiety and PTSD in MMD survivors. We evaluated the association of mental disorders with neurological disability and cognitive impairment, and further find out the independent protective and risk factors of neurological disability and cognitive impairment. In MMD survivors, the prevalence of these three mental disorders is high, 46.7% for depression, 50% for anxiety and 47.5% for PTSD. Anxiety and PTSD were significantly associated with more severe neurological disability (p = 0.039 and < 0.001); depression and anxiety were significantly associated with greater cognitive deficiency (p = 0.004 and 0.002). We further found PTSD was the only risk factor associated with neurological disability, and the corresponding odds ratio (OR) and 95% confidence interval (CI) was 81.74 (9.91–674.17); depression and anxiety were risk factors associated with cognitive impairment, and the corresponding OR and 95%CI were 2.73 (1.10–6.81) and 3.37 (1.29–8.78). Therefore, these three mental disorders were associated with more severe neurological disability and greater cognitive deficiency in MMD survivors. 相似文献

While several studies have investigated the effect of employees’ need for achievement on their work-related outcomes, how leader-follower congruence in need for achievement is related to critical workplace outcomes remains underexplored. Integrating person-environment theory and similarity-attraction theory, this study investigated the influences of leader-follower congruence in need for achievement on followers’ job performance and job well-being through the mediating effect of leader-member exchange (LMX). Using cross-level polynomial regression and response surface analysis to analyze the data from 391 leaders and 1,124 followers, we found that leader-follower congruence in need for achievement had a positive effect on followers’ job performance and job well-being though the mediating role of LMX. The theoretical and managerial implications are further discussed. 相似文献

E-learning systems are capable of providing more adaptive and efficient learning experiences for learners than traditional classroom settings. A key component of such systems is the learning policy. The learning policy is an algorithm that designs the learning paths or rather it selects learning materials for learners based on information such as the learners’ current progresses and skills, learning material contents. In this article, the authors address the problem of finding the optimal learning policy. To this end, a model for learners’ hierarchical skills in the E-learning system is first developed. Based on the hierarchical skill model and the classical cognitive diagnosis model, a framework to model various mastery levels related to hierarchical skills is further developed. The optimal learning path in consideration of the hierarchical structure of skills is found by applying a model-free reinforcement learning method, which does not require any assumption about learners’ learning transition processes. The effectiveness of the proposed framework is demonstrated via simulation studies. 相似文献

Prior work suggests that follower and leader risk orientation is positively associated with follower creativity. We suggest that this view is oversimplified and propose that follower creativity can be stimulated when leader and follower have diverging risk orientations. We, therefore, apply a configurational approach to creativity, evaluating varying combinations of leader and follower risk orientation on follower creativity. Across two field studies, we demonstrate that (a) follower creativity increases as leaders’ and followers’ risk orientations become more discrepant (i.e., incongruent); (b) follower creativity is higher when leader–follower dyads are congruent at moderate levels of risk orientation compared to congruence at the extremes (i.e., low and high levels); (c) follower‐experienced intellectual stimulation mediates the relationship between leader–follower risk orientation incongruence and congruence and follower creativity; and (d) that leader authority openness moderates the indirect effect of leader–follower risk orientation incongruence on creativity via follower‐experienced intellectual stimulation. Theoretical and practical implications specific to creativity and leader–follower relationships are discussed. 相似文献

Drawing on cue consensus theory and status characteristics theory, we argue that the consensus between newcomer voice (challenging vs. supportive) and organizational culture (individualistic vs. collectivistic) leads to observers' social cognition of warmth or competence. Based on two survey studies and two experiment studies, we found that individualistic organizational culture strengthens the positive relationship between challenging voice and perceived competence and that voice constructiveness mediates this moderating effect. We also found that collectivistic organizational culture strengthens the positive relationship between supportive voice and perceived warmth, and prosocial motivation mediates this moderating effect. Focusing on consistent cues between voice and organizational culture, our research contributes to the voice literature, answering when and how both newcomer challenging voice and supportive voice can lead to perceived warmth and competence. Our results offer both theoretical implications and practical insights for employees and organizations. 相似文献

This paper selects four dreams before and during COVID-19 which constellated the Plague God image in Chinese culture. The author argues that this shows evidence that the origins of the modern psyche, although hidden, are preserved and living within the ancient anima mundi. 相似文献
