ObjectiveTo explore the relationships between dispositional mindfulness (DM) and their post-traumatic stress symptoms (PTSS) of emergency nurses, and the mediating effects of coping styles and emotional exhaustion (EE).MethodsA cross-sectional survey study was conducted to collect data on DM, coping styles, EE, and PTSS among 571 emergency nurses from 20 hospitals in Chongqing, China. Correlation and structural equation models (SEMs) were used to evaluate the relationship among variables.ResultsEmergency nurses with lower dispositional mindfulness, higher emotional exhaustion and preference for negative coping (NC) revealed more PTSS. The effect of NC on PTSS was partially mediated by emotional exhaustion. Negative coping and emotional exhaustion played concurrent and sequential mediating roles between dispositional mindfulness and PTSS.ConclusionThis study has made a significant contribution to existing literature. It was suggested to develop interventions aimed at enhancing mindfulness, reducing negative coping strategies, and alleviating emotional exhaustion, which may be effective at reducing or alleviating post-traumatic stress symptoms of emergency nurses.

CEO leadership is considered a critical antecedent of product innovation performance, but the relational aspect of leadership has been largely neglected in this area. Drawing on upper echelons theory and relational leadership literature, this study explores whether, how, and when CEO relational leadership influences product innovation performance. Specifically, we analyze the underlying mechanism of TMT (top management team) voice behavior and two boundary conditions—TMT educational level and TMT age. Based on multi-source and multi-wave data on 105 Chinese firms, this study finds that CEO relational leadership plays an important role in promoting product innovation performance through the intervening mechanism of TMT voice behavior. Furthermore, the positive relationship between CEO relational leadership and TMT voice behavior is stronger in TMTs with higher educational level and lower age. This study contributes to the existing literature by empirically examining the under-investigated relationship between CEO relational leadership and product innovation performance, and by disentangling the underlying mechanism and boundary conditions.
