Belief in a Just World and Employee Voice Behavior: The Mediating Roles of Perceived Efficacy and Risk

Abstract

In this research, we hypothesized that employees’ belief in a just world (BJW) would be positively related to their voice behavior, i.e., the expression of ideas or opinions with the intention of engendering organizational improvement or change, and that this relation would be mediated by perceived voice efficacy and perceived voice risk. To test these hypotheses, we collected self-reported data from employees in two different countries: China (N?=?313) and Germany (N?=?190). The results revealed a positive association between BJW and employee voice behavior in both samples. The two-mediator model was confirmed in the Chinese sample, while only perceived voice efficacy played a mediating role in the German sample. Possible reasons for these differences may be related to differences in cultural dimensions and education levels between the samples. The findings emphasize the importance of bolstering employees’ belief in justice and the organizational climate, which influence perceived voice efficacy and risk, as means to increase organizational voice behavior.

父母婚姻质量与儿童内化问题:父母情绪表达的中介作用与儿童迷走神经活动的调节作用

基于家庭系统理论与个体-环境交互理论,研究考察了父母情绪表达在父母婚姻质量与儿童内化问题关系中的中介作用,以及儿童迷走神经活动的调节作用。研究选取155名6~7岁小学儿童为被试,运用便携式生理多道记录仪采集儿童静息与任务状态下的心电（ECG）与呼吸率,换算出基线RSA与RSA反应作为迷走神经活动的指标,采用母亲报告的《婚姻质量问卷》、《家庭情绪表达问卷》和《儿童行为量表》测评父母婚姻质量、父母情绪表达及儿童内化问题。结果发现：（1）父母婚姻质量负向预测小学儿童内化问题;（2）父母消极、积极情绪表达在父母婚姻质量与小学儿童内化问题关系中起中介作用;（3）小学儿童迷走神经张力（基线RSA）调节父母消极情绪表达与儿童内化问题关系。研究结果表明父母婚姻质量不仅直接影响儿童内化问题,同时会通过父母情绪表达间接地影响儿童内化问题。另外,较高迷走神经张力能够缓冲父母消极情绪表达对儿童内化问题的影响。     

内隐创业领导与多层次积极追随力的互动机制

多层次积极追随力是创业企业成长的重要保证。已有研究强调不同显性领导对积极追随力的影响, 结论存在较多争议。对此, 以内隐领导理论为基础, 构建了“内隐创业型领导-积极追随力”的多层次互动模型。根据此模型, 内隐创业型领导通过关系认同和领导代表性对个体与团队积极追随力产生促进作用; 团队积极追随力通过积极心理资本塑造内隐创业型领导; 团队差序氛围、员工传统性和领导特质调节焦点是互动关系重要的边界条件。     

Immediate-early Fos protein levels in brainstem neurons of male and female gonadectomized mice subjected to cold exposure

The expression of the immediate early gene c-fos has been used extensively as a marker for neural activation in response to acute and chronic stressful stimuli in brain and spinal cord. The present study examined the expression of Fos protein in the brainstem nuclei of male and female gonadectomized mice in response to cold stress. Free-floating sections were processed immunohistochemically for Fos protein using standard avidin-biotin complex methods. The number of Fos-positive neurons in each nucleus was determined. Although the experiment was designed to look for gender differences, results were equivalent between females and males. After mice were exposed to a cold ambient temperature (4 degrees C) for 2 h, elevated numbers of Fos-positive neurons were counted in the medullary gigantocellular reticular nucleus, medullary raphe nucleus, nucleus of the solitary tract and in locus coeruleus. However, no elevated expression was found in nucleus ambiguus, nor in neurons of the A1 group, nor the C2 or C3 group. Similar to rats, these results with mice reveal a widespread arousal system in the lower brainstem activated by cold stress in both genders. These findings in gonadectomized mice have set the stage for investigations following hormonal and genetic manipulations.     

Body image perceptions among Chinese children and adolescents

In order to investigate the body image self-perception and the prevalence of body dissatisfaction among Chinese children and adolescents, 9100 children aged 3-15 years living in four cities completed a questionnaire assessing body image self-percepts and ideals by figural stimuli. The results indicate that (1) children's body ratings started to be significantly related to their BMIs at age 5 and correlations increased with age; (2) a wide range of current body sizes was chosen by Chinese boys and girls; (3) the ideal body sizes of boys and girls selected by boys and girls, respectively, were "boys by boys">"boys by girls">"girls by boys">"girls by girls" and (4) the satisfaction, mild dissatisfaction, and moderate dissatisfaction rates were 40.1%, 36.4% and 23.5%, respectively. Differences as a function of gender and age were identified. It was concluded that the prevalence of body dissatisfaction among children and adolescents of urban China was striking, and that the Chinese boys were not immune to body dissatisfaction.     

浅谈栗谷的四端七情论

关于“四端七情”的问题在中国儒学尤其是朱熹哲学的心性论方面占有核心的位置 ,但并没有被朱熹以后的性理学者们继续关注 ,却得到韩国朝鲜王朝 ( 1 392— 1 91 0年 )的性理学者们的吸收及发挥。退溪与栗谷并称为韩国性理学的双璧 ,虽然他们都受到朱熹哲学的影响 ,不过在朱熹哲学的基础之上两位学者都建立了自己独特的哲学体系。栗谷的“四端七情说”在理气之妙、理通气局、气发理乘等理气论的基础上发挥了朱子学 ,他反对退溪理气互发的观点 ,对朱熹哲学作出了自己的理解和诠释     

Calcium signaling in mitral cell dendrites of olfactory bulbs of neonatal rats and mice during olfactory nerve Stimulation and beta-adrenoceptor activation

Synapses formed by the olfactory nerve (ON) provide the source of excitatory synaptic input onto mitral cells (MC) in the olfactory bulb. These synapses, which relay odor-specific inputs, are confined to the distally tufted single primary dendrites of MCs, the first stage of central olfactory processing. beta-adrenergic modulation of electrical and chemical signaling at these synapses may be involved in early odor preference learning. To investigate this possibility, we combined electrophysiological recordings with calcium imaging in olfactory bulb slices prepared from neonatal rats and mice. Activation of ON-MC synapses induced postsynaptic potentials, which were associated with large postsynaptic calcium transients. Neither electrical nor calcium responses were affected by beta-adrenergic agonists or antagonist. Immunocytochemical analysis of MCs and their tufted dendrites revealed clear immunoreactivity with antibodies against alpha1A (Cav2.1, P/Q-type) and alpha1B (Cav2.2, N-type), but not against alpha1C (Cav1.2, L-type) or alpha1D (Cav1.3, L-type) calcium channel subunits. Moreover, nimodipine, a blocker of L-type calcium channels, had no effect on either electrical or calcium signaling at ON-MC synapses. In contrast to previous evidence, we concluded that in neonatal rats and mice (P5-P8), mitral cells do not express significant amounts of L-type calcium channels, the calcium channel type that is often targeted by beta-adrenergic modulation. The absence of beta-adrenergic modulation on either electrical or calcium signaling at ON-MC synapses of neonatal rats and mice excludes the involvement of this mechanism in early odor preference learning.     

Posthypnotic suggestion and the modulation of Stroop interference under cycloplegia

Recent data indicate that under a specific posthypnotic suggestion to circumvent reading, highly suggestible subjects successfully eliminated the Stroop interference effect. The present study examined whether an optical explanation (e.g., visual blurring or looking away) could account for this finding. Using cyclopentolate hydrochloride eye drops to pharmacologically prevent visual accommodation in all subjects, behavioral Stroop data were collected from six highly hypnotizables and six less suggestibles using an optical setup that guaranteed either sharply focused or blurred vision. The highly suggestibles performed the Stroop task when naturally vigilant, under posthypnotic suggestion not to read, and while visually blurred; the less suggestibles ran naturally vigilant, while looking away, and while visually blurred. Although visual accommodation was precluded for all subjects, posthypnotic suggestion effectively eliminated Stroop interference and was comparable to looking away in controls. These data strengthen the view that Stroop interference is neither robust nor inevitable and support the hypothesis that posthypnotic suggestion may exert a top-down influence on neural processing.
