“赋能”还是“负担”?领导者授权行为对员工工作行为影响的双刃剑效应探究

在数字化经济迅速发展的时代, 领导者授权行为是一种激励员工的重要措施。然而, 以往关于领导者授权行为有效性的研究存在不一致发现。为了更深入地探讨领导者授权行为对员工的影响, 基于资源保存理论, 系统地构建了领导者授权行为对员工的“双刃剑”影响机制。具体而言, 第一, 基于资源视角, 将授权视为领导者为员工提供的资源, 深入分析领导者授权行为产生的“赋能”过程机制和“负担”过程机制, 并提出员工的调节定向是影响“双刃剑”机制的边界条件; 第二, 从动态角度看待领导者授权行为, 探讨领导者每日授权行为和领导者授权行为的日波动对员工的“双刃剑”影响机制; 第三, 从动态角度看待领导者授权行为所发生的组织情景。探讨相对动态的情景, 即工作事件, 对领导者授权行为“双刃剑”机制的影响。通过结合静态和动态的双重视角, 系统地探讨了领导者授权行为对员工的“双刃剑”影响机制, 具有一定的理论和实践意义。     

Attachment and social support mediate associations between Polyvictimization and psychological distress in early adolescence

The current study assesses associations between multiple experience of traumatic events (polyvictimization), PTSD symptoms (PTSS) and psychiatric symptoms in early adolescence, and explores the mediating roles of attachment orientations and perceived social support in the associations between polyvictimization, PTSS and psychiatric symptoms. In 2001, a representative national sample of 390 Danish eighth-graders (M = 13.95, SD = .37) completed validated self-report questionnaires. Polyvictimization was related to higher PTSS and psychiatric symptoms. Importantly, polyvictimization was significantly linked to high attachment anxiety, which was linked with low perceived social support, which in turn was linked with high PTSS levels and psychiatric symptoms. Polyvictimization might have dire consequences in early adolescence. An individual's high attachment anxiety might be connected with lack of perceived social support, which should be seen as a possible psychological distress mechanism subsequent to exposure to a number of potentially traumatic events.     

童年期创伤对大学生抑郁的影响:早期适应不良图式和负性生活事件的作用

目的:考察早期适应不良图式、负性生活事件在童年期创伤与大学生抑郁间的影响机制。方法:采用童年期创伤问卷、Young图式问卷短版中文修订版、青少年生活事件量表及90项症状自评量表对1423名大学生进行调查,结果表明:(1)童年期创伤既可以直接正向预测大学生抑郁,也可以通过早期适应不良图式中的分离和拒绝、自主性及能力受损两大图式类别间接地正向预测大学生抑郁;(2)负性生活事件调节了早期适应不良图式在童年期创伤与抑郁间的中介作用     

A preliminary analysis of self-control with aversive events: the effects of task magnitude and delay on the choices of children with autism

When faced with a choice between two aversive events, a person exhibits self-control by choosing a smaller, more immediate aversive event over a larger, delayed aversive event. Task demands are often aversive to children with autism and other developmental disabilities. The purpose of this study was to evaluate behavioral sensitivity to differences in the amount and delay of tasks as part of a preliminary study on self-control. Participants were 2 children with autism who engaged in problem behavior maintained by escape. Results indicated a lack of self-control with respect to choosing between two aversive tasks and suggested potential strategies for increasing self-control (i.e., choosing a small immediate task over a large delayed task).     

The role of language in memory for actions

Languages differ with respect to how aspects of motion events tend to be lexicalized. English typically conflates MOTION with MANNER, but Japanese and Spanish typically do not. We report a set of experiments that assessed the effect of this cross-linguistic difference on participants' decisions in a similarity-judgment task about scenes containing novel animations as stimuli. In Experiment 1, which required participants to encode the stimuli briefly into memory, we observed a language effect; in Experiment 2, which required participants to analyze the same stimuli, but not remember them, the language effect disappeared. Hence, these experiments reveal a task-dependent effect, which, we argue, points to working memory as the source of the language effect observed in Experiment 1 and, potentially, other experiments that have shown a linguistic relativity effect.     

Stressful events compromise control strivings during a major life transition

Prior research on stressful events has largely ignored their potential impact on motivational processes. This study prospectively examined the association of a stressful event with control strivings in the school-to-work transition. Five waves of data on stressful events, control strategies, and potential mediating variables were collected from an adolescent sample in Berlin (N = 420) during the year before high school graduation. The occurrence of a stressful event (death of family member, parent divorce) predicted a decline in general career-related and specific apprenticeship-related control strivings. This association was mediated by a decline in control-related means-ends beliefs. Proximity to the deadline of graduation exacerbated this association for apprenticeship-seeking control strivings, but this effect was buffered by usage of selective secondary control strategies (cognitive strategies to enhance commitment to a goal). Thus, stressful events can exacerbate challenges and require additional means of control striving.

帛书《周易》以史解经刍议

1973年长沙马王堆出土的帛书《周易》中的《缪和》篇中,有六则以历史故事解说《易经》卦爻辞的例子。本文分析这六则历史故事用以解经的符合程度,以证明用历史故事解经并不始于南宋的杨万里等人,而四库馆臣所谓"一变而胡瑗、程子,始阐明儒理;再变而李光、杨万里,又参证史事,《易》遂日启其论端",并非历史事实。
