Other-oriented emotional intelligence, OCBs, and job performance: a relational perspective.

In this study, we draw on social identity and social exchange theory to propose pathways via which emotional intelligence directed toward others in the organization has an impact on employee effectiveness. Findings from 122 supervisor-employee dyads showed that employees' other-oriented emotional intelligence is related to their organizational citizenship behaviors (OCBs) via the mechanisms of building high-quality exchanges with one's leaders and coworkers. We theorize and find evidence for unique mechanisms involved in mediating the effects of other-oriented emotional intelligence on taking charge and helping.

The ways to avoid abusive supervision: the moderating effects of the characteristics of supervisors and subordinates on abusive supervision.

Following the recent emphasis on supervisory interactions in abusive supervision, this study explains why and how supervisors' job insecurity and authoritarianism are related to abusive supervision and how subordinates' characteristics, agreeableness and negotiating resistance interact with the effects of supervisors' characteristics. We conducted a field study with 261 supervisor and subordinate dyads in South Korea, and the study findings confirmed that supervisors' authoritarianism is positively related to abusive supervision and that the effect is enhanced when subordinates are highly agreeable and display resistant behaviors. The study contributes to the leadership literature, particularly on abusive supervision and personality.

When Does Group Efficacy Deteriorate Group Performance? Implications of Group Competency.

While the social cognitive theory suggests that a group's efficacy belief enhances its performance, emerging evidence indicates that this relationship is more complex than it appears to be. This study explores the boundary conditions of this relationship using the data of 389 employees from 41 work groups in a manufacturing company in South Korea. The results show that group efficacy is positively related to group performance and that this relationship is stronger when members are generally incompetent than competent.

Urine and Serum Electrolytes and Biochemical Values Associated with Osteoporosis in Premenopausal and Postmenopausal Women: A Longitudinal and Cross-Sectional Study Using Korean Genome and Epidemiology Study (KoGES) Cohort.

Osteoporosis is a major public health concern, especially in women. This study aims to identify early biomarkers from biochemical measurements of serum and urine for recognizing the development of osteoporosis and osteopenia in premenopausal and postmenopausal women. From the Korean Genome and Epidemiology Study (KoGES) cohort, longitudinal study participants with normal bone density were enrolled and assessed for the association of baseline clinical and biochemical factors with osteoporosis development over 4 years.
