To fill the previous research gap, focusing on two constructs, i.e. perceived supervisor support (PSS) and psychological capital (PsyCap), this study aims to explore the mechanism underlying the relationship between teaching–research conflict (TRC) and job burnout among university teachers using the lens of job demands–resources (JD-R) model.

First, theoretically grounded hypotheses linking teaching–research conflict, PSS and PsyCap to job burnout were formulated. Then, a cross-sectional design was used to test the theoretical model presented in this study.

The results showed that TRC was positively linked to emotional exhaustion (EE) and depersonalization (DP), but negatively linked to personal accomplishment; PSS moderated the effect of TRC on both EE and DP but did not act as a moderator in the relationship between TRC and personal accomplishment; and PsyCap moderated the effect of TRC on all the three dimensions of job burnout.

Given that the data were collected from single-source, the study was vulnerable to the common method variance. Besides, the relative small sample size limits the representativeness of the sample. Moreover, the cross-sectional design cannot confirm causal relationship between variables. Despite these limitations, the findings of this research can potentially inform effective interventions aimed at reducing the effect of TRC on job burnout among university teachers.

Based on the JD-R model, PSS and PsyCap are used to explore the effect of TRC on job burnout for the first time.

The purpose of this study is to explore the relationship between leadership styles, psychological capital and job engagement.

Data were collected among knowledge workers working no less than 1 year in three high-tech enterprises in Henan Province, China. The investigation was conducted with the cooperation from the human resource departments of the selected enterprises from August to October 2014. To minimize potential common method bias, the authors adopted a cross-lagged design with a time gap of four months. The statistical methods included descriptive statistics, structural equation modeling (SEM) and bootstrap analysis.

The results showed: leadership styles significantly influenced employees’ psychological capital and work engagement; specifically, transformational and transactional leadership positively predicted employees’ psychological capital and work engagement; compared with transactional leadership, transformational leadership had stronger predictive power to employees’ psychological capital and work engagement; employees’ psychological capital positively predicted their work engagement; and employees’ psychological capital acts as partial mediator between leadership styles and employees’ work engagement.

Although a body of studies have shown that leadership is an important factor influencing employees’ work attitude and outcomes, it is only in recent years that the effect mechanism of leadership becomes a hot subject in organizational behavior and management fields. As for leadership styles, in general, most research concerned transformational leadership, rather than transactional leadership and only a little of research compared the effects of transformational leadership and transactional leadership on employees’ work outcomes. In terms of outcomes of leadership, as noted earlier, the previous research mainly explored job performance, job satisfaction, innovation behavior, job burnout and so on. Regarding the effect of leadership styles on employees’ work engagement, in spite of more and more supportive evidence of the link between transformational leadership and work engagement, few studies examined the relationship between transactional leadership and work engagement. What’s more, to the best of our knowledge, till now, no empirical research has explored the internal mechanism of this effect from the perspective of psychological capital. Therefore, the present study is a breakthrough for the direct model of leadership styles and employees’ engagement, theoretically bridges the research gap and contributes to the existing literature by presenting a new picture of leadership behavior effect mechanism.

The purpose of this paper is to examine the effects of protean career orientation (PCO) and psychological capital (PsyCap) on well-being among knowledge workers.

The author adopted a two-wave cross-lagged design. In total, 518 knowledge workers at three enterprises in China were sampled to complete the Direnzo et al.’s (2015) Protean Career Orientation Questionnaire, Luthans et al.’s (2007) Psychological Capacity Questionnaire, and Ryff and Keyes’ (1995) Psychological Well-Being Scale. The main statistical methods involved descriptive statistics, structural equation modeling, and bootstrapping analysis.

The findings of the study were as follows: PCO positively predicted PsyCap among knowledge workers; both PCO and PsyCap positively contributed to knowledge workers’ well-being; and knowledge workers’ PsyCap partially mediated the relationship between their PCO and well-being.

Rare empirical studies were conducted on the relationship between PCO and psychological well-being. The previous findings are inconsistent on whether PCO is an antecedent of PsyCap, or PsyCap is an antecedent of PCO. The author conducted a cross-lagged survey to examine the above relationships; to certain extent, the present study addresses the research gap and contributes to the burgeoning literature.

Previous research has linked upward social comparison on social network sites (SNSs) to depressive symptoms; however, the mechanism underlying this relationship remains unclear. The purpose of this paper is to explore the roles of envy and self-efficacy in the relationship between upward social comparison on SNSs and depressive symptoms.

Based on the social comparison theory and previous related literature, a moderated mediation model integrating upward social comparison on SNSs, depressive symptoms, envy and self-efficacy was developed and empirically examined based on the data collected from 934 Chinese high school students.

The structural equation modeling analysis shows that envy partially mediates the relationship between upward social comparison on SNSs and depressive symptoms, whereas self-efficacy moderated both the direct effect of upward social comparison on SNSs on depressive symptoms and the mediating effect of envy in the relationship between upward social comparison on SNSs and depressive symptoms.

The findings offer interesting implications for guiding adolescents to use SNSs properly. This study found that envy and self-efficacy act as a mediator and moderator, respectively, between upward social comparison on SNSs and depressive symptoms, indicating that reducing envy and enhancing self-efficacy should be feasible to alleviate the negative effect of SNSs use.

In order to alleviate the negative effect of SNSs use, parents and educators should direct adolescents to view others’ achievements and happiness properly and manage to improve self-efficacy among adolescents with poor self-efficacy through effective training.

Through building and examining a moderated mediation model integrating envy and self-efficacy into the relationship between upward social comparison on SNSs and depressive symptoms, the present study advances our understanding of how and when upward social comparison on SNSs augments the risk of depressive symptoms among adolescents.
