如何激发员工绿色行为?绿色变革型领导与绿色人力资源管理实践的作用

鉴于当今环境问题的严峻性, 如何激发绿色行为逐渐成为社会各界关注的一个话题。本研究从绿色变革型领导和绿色人力资源管理实践两大绿色管理利器入手, 探究两者能否共同激发员工绿色行为。基于以往文献, 本研究提出两组竞争性假设：基于线索一致理论, 认为绿色变革型领导与绿色人力资源管理实践正向交互影响员工绿色行为; 此外, 基于领导替代理论, 认为绿色变革型领导与绿色人力资源管理实践负向交互影响员工绿色行为。研究1a (N = 91)和研究1b (N = 220)采用实验法, 发现绿色变革型领导与绿色人力资源管理实践发挥协同作用, 正向交互预测员工绿色行为。研究2采用问卷法, 搜集了三时点上下级配对数据(N = 173), 不仅再次支持了研究1的发现, 还进一步揭示环保目标清晰度的中介作用。以上结果支持了线索一致性理论在绿色管理领域的适用性, 并启示企业在绿色管理过程中可以软硬兼施, 联合运用绿色变革型领导和绿色人力资源管理实践两大策略。     

儿童拒绝敏感性与自我知觉的关系:一项交叉滞后研究

采用儿童拒绝敏感性问卷与儿童自我知觉量表对596名中小学儿童进行了为期一年的追踪调查,通过交叉滞后回归分析考察儿童拒绝敏感性与多种自我知觉间的预测关系。结果发现：（1）自我知觉的年级差异显著,初中儿童的自我知觉水平较低;（2）在两次测量中,拒绝敏感性与多种自我知觉均呈显著的负相关;（3）控制性别、年级以及自身稳定性之后,第一年的多种自我知觉均可以负向预测第二年的拒绝敏感性,而第一年的拒绝敏感性仅可以负向预测第二年的体貌及一般自我知觉;（4）年级调节了拒绝敏感性与一般和行为自我知觉间的纵向关系,并在小学与初中儿童中表现出不同的模式。研究证实自我知觉是儿童拒绝敏感性形成的重要原因之一,为儿童社会认知及心理健康的相关研究提供新的实证依据。     

胚胎期糖皮质激素系统在光照改善小鸡记忆中的作用

该研究采用胚胎期药物注射法和小鸡一次性被动回避反应行为模型,观察了皮质酮和地塞米松对暗孵化小鸡记忆的影响,以及两类皮质激素受体颉颃剂RU-486和Spironolactone对光照以及皮质酮效应的阻断作用。结果表明,糖皮质激素可明显改善暗孵化小鸡的记忆;两类受体颉颃剂均阻断了光照和皮质酮对暗孵化小鸡记忆的改善作用,但糖皮质激素受体对小鸡记忆的作用是特异性的,盐皮质激素主要通过对小鸡的基本状态的改变来影响记忆活动。因此,糖皮质激素及其受体系统参与了光照对小鸡记忆的作用过程。     

糖皮质激素与记忆

对近年来有关糖皮质激素对记忆的作用的研究进行了小结。由于糖皮质激素的受体广泛分布在与记忆行为相关的脑区,而且对相应的神经元可塑性进行调节,因此糖皮质激素对个体的记忆的形成有着重要的影响。     

Patterns of vocal fold movement during stuttering

By means of an electroglottography, 114 tokens of stuttering produced by 12 adult stutterers were analyzed for patterns of vocal fold vibration as observed in eight types of stuttering episodes. Results suggest that stuttering events share certain phonational attributes. Issues concerning the nature of the disorder and approach to treatment are discussed.     

Androgyny,stress, and satisfaction: Dual- career and traditional relationships

Forty-one female and 61 male assistant professors, of whom 46% were involved in dual-career relationships, responded to a mail questionnaire that assessed (1) androgyny; (2) satisfaction at work, home, and in their personal life; (3) stress at work, home, and in their personal life. A 2×2×2 analysis of variance was conducted to evaluate the effects of relationship status, androgyny, and sex of subject. The results indicated that being androgynous was associated with increased work stress, but simultaneously increased personal satisfaction. A significant interaction between androgyny and relationship status demonstrated that androgynous dual-career persons reported highest personal satisfaction; androgynous nondual-career persons reported highest work satisfaction. Dualcareer status increased personal and work stress, as well as relationship satisfaction. The importance of considering each person's specific life situation when evaluating androgyny as a positive or negative attribute is discussed.     

Theme centered group psychotherapy with psychiatrically hospitalized preadolescent boys

This paper describes how a particular content can be ascribed to verbal group work with psychiatrically hospitalized children. This focus can then provide the basis for psychotherapeutic intervention in which resistance and transference are interpreted while underlying conflicts are uncovered and worked on. The theme of the group, health issues and sexuality, was derived from the children's expressed needs on the unit. The use of psychotherapy as a basis for subsequent education about these health issues is discussed. Also described is the way in which the verbal medium was used in conjunction with other unit procedures.     

Ocular motility and cognitive process

This study investigates the amount of ocular motility occuring in response to questions varying the kind of cognitive process required for answer. Fewer eye movements occur in response to questions designed to elicit visuo-spatial as compared to verbal-conceptual processes, a finding consistent with our earlier observation of more ‘stares’ occuring with the former than with the latter questions. The results are inconsistent with the traditional hypothesis that visual imagery involves an increase in scanning eye movements. The findings are interpreted in terms of a model postulating an interaction of the form of visual information processing and the type of cognitive activity subjects engage in.     

Necessary versus sufficient causal schemata for success and failure

197 subjects judged the perceived presence or absence of ability or effort, given information about task outcome (success or failure), the difficulty of the task (easy, intermediate, or difficult), and the state of the complementary cause (effort or ability). The data revealed that a multiple sufficient causal schema is used to explain common events. That is, the presence of ability or effort is perceived as enough to produce success at an easy task, while the absence of ability or effort is perceived as sufficient to result in failure at a difficult task. On the other hand, a multiple necessary schema tends to be employed to explain uncommon events. Success at a difficult task is believed to require both ability and effort, while failure at an easy task tends to be perceived as caused by low ability and low effort. In addition, there were disparities in the causal judgments for success and failure: failure outcomes are more likely to elicit a multiple sufficient schema. Further, in achievement-related contexts ability and effort are perceived as negatively covarying causal determinants of typical successes and failures. In addition to supporting hypotheses from attribution theory, the data shed further light upon the perceived determinants of success and failure, and demonstrate the influence of cognitive structures on achievement-related causal judgments.
