Openness to Experience,Ethical Leadership,and Innovative Work Behavior

Drawing on trait activation theory, we examine ethical leadership as a boundary condition on the relationship between openness to experience and innovative work behavior. We collected data from 291 subordinates and 51 supervisors to test our theoretical model. Our results suggest that openness to experience was positively related to innovative work behavior. Furthermore, this relationship was only significant when ethical leadership was perceived high as compared to low. Our research contributes to the literatures on innovative work behavior and ethical leadership.     

Consequences of Supervisor Knowledge Hiding in Organizations: A Multilevel Mediation Analysis

Drawing on the theoretical framework of social cognitive theory, our study explores the multilevel mediation model in which moral disengagement (level-1) mediates the direct relationships between knowledge hiding by supervisors from subordinates (KHSS: level-2) and supervisor directed organizational citizenship behavior (SOCB: level-1) and supervisor directed silence (SS: level-1). Drawing on multi-sourced, multi-timed, and multilevel data of 306 subordinates nested within 83 supervisors, multilevel structural equation modeling (ML-SEM) was used to test the proposed model. The results demonstrate that KHSS, first, fosters subordinates’ moral disengagement, which in turn reduces their SOCB and enhances their SS. Our findings offer several useful theoretical and managerial implications of the negative consequences of supervisor knowledge hiding in organizations. As one of the first studies to provide empirical evidence for the existence of supervisor knowledge hiding (i.e. KHSS), this research highlights the consequences of KHSS on subordinates’ moral disengagement, SOCB, and SS.     

Job Stress and Employee Well-Being Among Airline Personnel in an Asian Developing Country

This study examined the relationship between job stress and employees' well-being in a developing country in Asia. Job stress was operationalized in terms of perceived experiences at jobs which were chronic in nature. Employee well-being was operationalized in terms of organizational commitment, job involvement, and job satisfaction. Data were collected by means of a structured questionnaire from 150 employees working in a national carrier in a developing country in Asia. Pearson correlation and moderated multiple regression were used to analyze the data. Job stress was significantly related to organizational commitment and job satisfaction. Moderated multiple regression did not support the role of gender as a moderator of the stress–outcome relationship.     

De novo mRNA synthesis is required for both consolidation and reconsolidation of fear memories in the amygdala

Memory consolidation is the process by which newly learned information is stabilized into long-term memory (LTM). Considerable evidence indicates that retrieval of a consolidated memory returns it to a labile state that requires it to be restabilized. Consolidation of new fear memories has been shown to require de novo RNA and protein synthesis in the lateral nucleus of the amygdala (LA). We have previously shown that de novo protein synthesis in the LA is required for reconsolidation of auditory fear memories. One key question is whether protein synthesis during reconsolidation depends on already existing mRNAs or on synthesis of new mRNAs in the amygdala. In the present study, we examined the effect of mRNA synthesis inhibition during consolidation and reconsolidation of auditory fear memories. We first show that intra-LA infusion of two different mRNA inhibitors dose-dependently impairs long-term memory but leaves short-term memory (STM) intact. Next, we show that intra-LA infusion of the same inhibitors dose-dependently blocks post-reactivation long-term memory (PR-LTM), whereas post-reactivation short-term memory (PR-STM) is left intact. Furthermore, the same treatment in the absence of memory reactivation has no effect. Together, these results show that both consolidation and reconsolidation of auditory fear memories require de novo mRNA synthesis and are equally sensitive to disruption of de novo mRNA synthesis in the LA.     

Psychometric Properties of the WHOQOL-BREF Questionnaire among Disabled Students in Malaysian Higher Learning Institutions

This study aims to evaluate reliability, internal consistency and dimensional structure of the World Health Organization Quality of Life (WHOQOL-BREF) among disabled students. The study covers 127 disabled students studying in public universities, 26 in private universities, 109 in polytechnic and 19 studying in community colleges. The World Health Organization Quality of Life Abbreviation (WHOQOL-BREF) has been used to assess QOL. The reliability and validity of the questionnaire were evaluated by Cronbach’s alpha (α) and Pearson’s correlation coefficients. Alpha scores greater than or equal to 0.6 are considered to denote acceptable and adequate internal consistency. Correlation matrix also showed satisfactory results in all domains. Factor analysis was carried out using the principal components method with varimax rotation to examine the dimensional structure of the questionnaire. This study has provided some preliminary evidence of the reliability and validity of the WHOQOL-BREF to be used for evaluating quality of life among disabled students.     

The Mediating Role of Discrete Emotions in the Relationship Between Injustice and Counterproductive Work Behaviors: A Study in Pakistan

Purpose

Our study explores the mediating role of discrete emotions in the relationships between employee perceptions of distributive and procedural injustice, regarding an annual salary raise, and counterproductive work behaviors (CWBs).

Design/Methodology/Approach

Survey data were provided by 508 individuals from telecom and IT companies in Pakistan. Confirmatory factor analysis, structural equation modeling, and bootstrapping were used to test our hypothesized model.

Findings

We found a good fit between the data and our tested model. As predicted, anger (and not sadness) was positively related to aggressive CWBs (abuse against others and production deviance) and fully mediated the relationship between perceived distributive injustice and these CWBs. Against predictions, however, neither sadness nor anger was significantly related to employee withdrawal.

Implications

Our findings provide organizations with an insight into the emotional consequences of unfair HR policies, and the potential implications for CWBs. Such knowledge may help employers to develop training and counseling interventions that support the effective management of emotions at work. Our findings are particularly salient for national and multinational organizations in Pakistan.

Originality/Value

This is one of the first studies to provide empirical support for the relationships between in/justice, discrete emotions and CWBs in a non-Western (Pakistani) context. Our study also provides new evidence for the differential effects of outward/inward emotions on aggressive/passive CWBs.     

Sensorimotor Impairment of Speech and Hand Movement Timing Processing in Parkinson’s Disease

Models of motor control have highlighted the role of temporal predictive mechanisms in sensorimotor processing of speech and limb movement timing. We investigated how these mechanisms are affected in Parkinson’s disease (PD) while patients performed speech and hand motor reaction time tasks in response to sensory stimuli with predictable and unpredictable temporal dynamics. Results showed slower motor reaction times in PD vs. control in response to temporally predictable, but not unpredictable stimuli. This effect was driven by faster motor responses to predictable stimuli in control subjects; however, no such effect was observed in the PD group. These findings indicated the relationship between PD pathology and sensorimotor deficits in temporal predictive mechanisms of timing processing during speech production and hand movement.     

Consuming experience: Why affective forecasters overestimate comparative value

The hedonic value of an outcome can be influenced by the alternatives to which it is compared, which is why people expect to be happier with outcomes that maximize comparative value (e.g., the best of several mediocre alternatives) than with outcomes that maximize absolute value (e.g., the worst of several excellent alternatives). The results of five experiments suggest that affective forecasters overestimate the importance of comparative value because forecasters do not realize that comparison requires cognitive resources, and that experiences consume more cognitive resources than do forecasts. In other words, because forecasters overestimate the extent to which they will be able to think about what they did not get while experiencing what they got.
