Too powerless to speak up: Effects of social rejection on sense of power and employee voice

Enabling and amplifying the voice of employees creates opportunities for organizational improvement. Prior research has shown that employees' sense of power has impact on their voice behavior. As such, when would employees feel too powerless to speak up in the workplace? The current study investigates the indirect effect of social rejection (via sense of power) on employee voice. We use conservation of resources theory to explain this relationship. Experimental data from two studies demonstrate that participants reminded of social rejection (vs. acceptance) exhibit a lower sense of power. Specifically, we observe that social rejection diminishes a person's sense of power, and that social acceptance does not enhance this sense. That is, social rejection has an indirect effect on employee voice through sense of power. We discuss the theoretical and practical implications of our findings with regard to social rejection, sense of power, and workplace voice behavior.     

与彼得·辛格的对话

对话的主题涉及辛格对马克思、全球伦理、道德责任、动物解放、伦理思维中的直觉层次与批判层次以及伦理的客观性问题。辛格哲学的特点不仅在于他始终不懈地将伦理的思维与减少痛苦与苦难的价值付诸行动,而且也在于他拓宽伦理思维的能力。辛格博采生物学、历史学、人类学、经济学以及博弈论研究成果,丰富并阐明了伦理理论与实践何以可以被现实赋予活力。当我们转向辛格的哲学时,我们会发现一种伦理的生活方式:不仅仅为此刻活着,也不仅仅根据个人喜好活着,而是去过一种具有更广意义的生活,它要求献身于所有有感受能力的生命的福祉和环境保护之中。     

The Effects of Marital Conflict on Korean Children’s Appraisal of Conflict and Psychological Adjustment

This study examined the effects of marital conflict on Korean children’s psychological adjustment and appraisal of hypothetical marital conflict situations. Children between the ages of 10 and 12 were divided into “high-conflict” (n = 58) and “low-conflict” (n = 58) groups based on their self-reported degree of perceived interparental conflict in the home environment. Hypothetical marital conflict situations were provided in cartoon format, and were differentiated based conflict intensity (verbal versus physical aggression) and content (child-related conflict versus non-child-related conflict). In general, children reported greater negative affect and perceived threat to hypothetical conflict situations involving physical aggression compared to situations involving verbal conflict. In child-related conflict situations, children reported more fear of being drawn in and endorsed coping strategies that involved direct intervention. “High-conflict group” children evidenced stronger reactivity in responding to marital conflict situations in general and endorsed indirect intervention strategies—a finding previously not found in similar studies conducted with European-American children—indicating the possibility of cross-cultural difference in coping preferences in interparental conflict situations. Furthermore, “high-conflict group” children manifested more indices of maladjustment as indicated by externalizing and internalizing behavior problems, in addition to more self-reported depressive symptoms. Results highlight the effects of marital conflict on children’s psychological adjustment and indicate the possibility of cross-cultural differences in preferred coping mechanism in interparental conflict situations for Korean children.     

Definition of Financial Abuse: A Culture-Centered Construct among Korean Elders

One of the critical issues in addressing financial abuse in Korea is the absence of an appropriate definition voiced by the elderly. This study is designed to explore how Korean elders define financial abuse in given social and cultural contexts. Face-to-face, in-depth interviews were conducted with 124 elders, aged 60 to 79, residing in Korea. The results of qualitative data analysis using grounded theory revealed that a vast majorty of Korean elderly respondents defined financial abuse as lack of provision of financial support to elder parents, and a small portion of respondents defined it as financial exploitation by adult children. The definition of financial abuse reflects cultural beliefs based on filial piety about financial expectations within the parent–child relationship. Education on financial abuse for both elders and their adult children and establishment of income support programs are urgently needed efforts to increase the financial well-being of elderly Koreans.     

Postural Asymmetries in Response to Holding Evenly and Unevenly Distributed Loads During Self-Selected Stance

The authors examined postural asymmetries during quiet stance and while holding evenly or unevenly distributed loads. Right-hand dominant subjects preferentially loaded their right lower limb when holding no load or a load evenly distributed in both hands, but no differences in center of pressure (CoP) were observed between the left and right limbs. However, longer CoP displacement was observed under the preferentially loaded limb, which may reflect a functional asymmetry that allows quick movement of one limb in response to a potential perturbation. When a load was held only in the nondominant hand, sample entropy decreased in the left (loaded) limb but increased in the right (unloaded) limb, suggesting the unloaded foot compensated for a loss of control flexibility in the loaded foot.     

Phosphorylation of mitogen-activated protein kinase in the medial prefrontal cortex and the amygdala following memory retrieval or forgetting in developing rats

We examined neuronal correlates of forgetting in rats by detection of phosphorylated mitogen-activated protein kinase (pMAPK) in the medial prefrontal cortex (mPFC) and amygdala. In Experiment 1, postnatal day (P)23 and P16 rats received paired noise CS-shock US presentations. When tested immediately after conditioning, P23 and P16 rats exhibited similar levels of conditioned fear; when tested after 2 days, however, P16 rats showed poor CS-elicited freezing relative to P23 rats. In Experiment 2, P16 and P23 rats received either paired or unpaired CS-US presentations, and then were tested 48 h later. Consistent with Experiment 1, P16 rats showed forgetting whereas P23 rats exhibited good retention at test. Additionally, unpaired groups showed poor CS-elicited freezing at test. Immunohistochemistry showed that P23 and P16 rats given paired presentations exhibited significant elevation of pMAPK-immunoreactive (ir) neurons in the amygdala compared to rats given unpaired presentations. That is, MAPK phosphorylation in the amygdala tracked learning history rather than behavioral performance at test. In contrast, only the P23-paired group showed an elevated number of pMAPK-ir neurons in mPFC, indicating that MAPK phosphorylation in the mPFC tracks memory expression. Different test-perfusion intervals were employed in Experiment 3, which showed that the developmental dissociation in the pMAPK-ir neurons observed in the mPFC in Experiment 2 was not due to age differences in the rate of phosphorylation of MAPK. These findings provide initial evidence suggesting that while the mPFC is involved in memory retrieval, MAPK phosphorylation in the amygdala may be a persisting neural signature of fear memory.     

Genetic and environmental influences on antisocial behavior: a meta-analysis of twin and adoption studies

A meta-analysis of 51 twin and adoption studies was conducted to estimate the magnitude of genetic and environmental influences on antisocial behavior. The best fitting model included moderate proportions of variance due to additive genetic influences (.32), nonadditive genetic influences (.09), shared environmental influences (.16), and nonshared environmental influences (.43). The magnitude of familial influences (i.e., both genetic and shared environmental influences) was lower in parent-offspring adoption studies than in both twin studies and sibling adoption studies. Operationalization, assessment method, zygosity determination method, and age were significant moderators of the magnitude of genetic and environmental influences on antisocial behavior, but there were no significant differences in the magnitude of genetic and environmental influences for males and females.     

Perception and Help-Seeking Intention of Intimate Partner Violence in Later Life: An International Perspective

This study examines whether elderly Koreans recognize a scenario of intimate partner violence as such and whether they would seek help in the given situation of elder mistreatment (EM). Two cohorts of Korean elders (one immigrant and one Korea-based), each numbering 124 participants, were recruited using a quota sampling strategy. The study used a mixed method approach, employing a hypothetical scenario, and patriarchy theory informed the study. Findings revealed low perception of the vignette as EM and low help-seeking intention in both cohorts. Among the immigrant cohort, intention to seek help was greater among respondents who were female, demonstrated lower adherence to traditional values, and perceived the vignette as EM. Among the Korea-based cohort, the only significant factor was recognition of the scenario as EM. Development of culturally competent and geographically specific practice and intervention is urgently needed, particularly among elders who have greater adherence to traditional cultural values.
