This research aimed to examine whether workplace gender diversity moderates the psychological effects of job characteristics (i.e., task interdependence and role ambiguity) on employees in Japanese organizations. We conducted two employee surveys, Study 1 in two service industry companies, and Study 2 in a HR service company. As a result, the negative interaction effects of task interdependence and workplace gender diversity on affective commitment were found both in Study 1 and 2. Specifically, task interdependence increased affective commitment of employees only when gender diversity was relatively low. A multilevel analysis performed in Study 2 also revealed that individual level role ambiguity had the same interaction effect. These results indicate that workplace gender diversity needs to be treated as an important contextual factor in job characteristics research.
The purpose of this study is to clarify the influence of preceding factors on the coaching behaviors of emergency life-saving technicians. The antecedents include implicit person theories (IPTs) about the personality and personal attributes (e.g., personality and ability), experiential learning behaviors, and experiences of being coached from their managers. We investigated and analyzed 351 emergency life-saving technicians concerning the relationship with these factors and coaching behaviors. The results showed that the incremental theory, experiential learning behaviors, and experiences of being coached by their managers had a positive influence on their own coaching behaviors. It was also found that experiences of being coached by their managers mediated experience learning behaviors, affecting their coaching behaviors. Implications for coaching behaviors research and practice are discussed.
