Effects of authentic leadership on work–family balance in China

The purpose of this paper is to examine the effects of authentic leadership on the work–family balance (WFB) of followers by focusing on the mediating roles of leader–member exchange (LMX) and work-to-family enrichment (WFE) and the moderating role of traditionality in China

Family ostracism and proactive customer service performance: An explanation from conservation of resources theory

Despite the burgeoning interest in work-family conflict, little is known about how family stressors influences employees’ attitudes and behaviors in the workplace. This study focused on family ostracism and investigated its impact on employees’ proactive customer service performance (PCSP). Drawing on conservation of resources (COR) theory, this study further examined the mediating role of emotional exhaustion and the moderating role of family centrality. Using time-lagged data from 264 supervisor-follower dyads of two hotels in the mainland of China, this study found that family ostracism negatively affected employees’ PCSP by eliciting emotional exhaustion. In addition, the findings indicated that family centrality strengthened the direct effect of family ostracism on emotional exhaustion and the indirect effect of family ostracism on PCSP via emotional exhaustion such that the relationships were stronger when family centrality was high. Finally, this study discussed the theoretical implications of these results and provided practical several implications for organizations

The antecedents and consequences of being envied by coworkers: An investigation from the victim perspective

This study focused on the victims of coworker envy and presented a comprehensive model of being envied by coworkers to explore its antecedents and consequences in the hospitality context. Based on a sample of 232 employee-supervisor dyads in five Chinese hotels, we found that competitive goal interdependence fostered coworker envy, whereas cooperative goal interdependence prevented it. Further, the experience of being envied by coworkers undermined the frontline hospitality employees' social exchange relationship with coworkers. This in turn prevented them from engaging in organizational citizenship behavior directed at their organizations (OCBO) and specific individuals (OCBI) such as organization members. In addition, envied employees' others' approval of the contingent self-esteem was found to strengthen (1) the direct effect of being envied by coworkers on coworker exchange and (2) the indirect effect of being envied by coworkers on OCBO and OCBI via coworker exchange

Fuel the service fire The effect of leader humor on frontline hospitality employees' service performance and proactive customer service performance

Purpose Drawing from self-determination theory, this study aims to examine the effect of leader humor on frontline hospitality employees' service performance and proactive customer service performance (PCSP) via harmonious passion (HP) for work with employee neuroticism as the moderating mechanism. Design/methodology/approach This study controlled for the nested effect and tested all the hypotheses with Mplus 7.0 using a time-lagged three-wave survey of 232 Chinese supervisor-subordinate dyads. Findings The results indicated that leader humor promotes frontline hospitality employees' service performance and PCSP by enhancing their HP. Furthermore, neuroticism was shown to strengthen the direct impact of leader humor on employee HP and its indirect impact on employee service performance and employee PCSP through HP. Originality/value First, this research contributes to the leader humor literature through exploring its impact on the service performance and PCSP of frontline hospitality employees. Second, this research develops a new framework to explain the leader humor-employee service outcomes relationship using self-determination theory. Finally, the focus on the moderating role of neuroticism helps to explain the "when" question of leader humor

Perceived organizational exploitation and organizational citizenship behavior:a social identity perspective

Based on social identity theory, this research investigates the mechanism between perceived organizational exploitation and employees' organizational citizenship behavior. Using data collected from 340 supervisor-subordinate dyads in 6 hotels in China, our findings indicate that perceived organizational exploitation negatively influences employees' OCB. Moreover, organizational identification is found to fully mediate the associations between perceived organizational exploitation and employees' OCB. Furthermore, power distance weakens the direct effect of perceived organizational exploitation on organizational identification, as well as its indirect effects on employees' OCB. The theoretical and managerial implications of these findings are discussed

Genetic evidence strengthens the bidirectional connection between gut microbiota and periodontitis: insights from a two-sample Mendelian randomization study

Abstract Background Recent research has established the correlation between gut microbiota and periodontitis via oral-gut axis. Intestinal dysbiosis may play a pivotal bridging role in extra-oral inflammatory comorbidities caused by periodontitis. However, it is unclear whether the link is merely correlative or orchestrated by causative mechanistic interactions. This two-sample Mendelian randomization (MR) study was performed to evaluate the potential bidirectional causal relationships between gut microbiota and periodontitis. Materials and Methods A two-sample MR analysis was performed using summary statistics from genome-wide association studies (GWAS) for gut microbiota (n = 18,340) and periodontitis (cases = 12,251; controls = 22,845). The inverse-variance weighted (IVW) method was used for the primary analysis, and we employed sensitivity analyses to assess the robustness of the main results. The PhenoScanner database was then searched for pleiotropy SNPs associated with potential confounders. In order to identify the possibly influential SNPs, we further conducted the leave-one-out analysis. Finally, a reverse MR analysis was performed to evaluate the possibility of links between periodontitis and genetically predicted gut microbiota alternation. Results 2,699 single nucleotide polymorphisms (SNPs) associated with 196 microbiota genera were selected as instrumental variables (IVs). IVW method suggested that order Enterobacteriales (OR: 1.35, 95% CI 1.10–1.66), family Bacteroidales S24.7group (OR: 1.22, 95% CI 1.05–1.41), genus Lachnospiraceae UCG008 (OR: 1.16, 95% CI 1.03–1.31), genus Prevotella 7 (OR: 1.11, 95% CI 1.01–1.23), and order Pasteurellales (OR: 1.12, 95% CI 1.00–1.26) may be associated with a higher risk of periodontitis, while genus Ruminiclostridium 6 may be linked to a lower risk (OR: 0.82, 95% CI 0.70–0.95). The sensitivity and heterogeneity analyses yielded no indication of horizontal pleiotropy or heterogeneity. Only the association between order Enterobacteriales and the likelihood of periodontitis remained consistent across all alternative MR approaches. In the reverse MR analysis, four microbiota genera were genetically predicted to be down-regulated in periodontitis, whereas two were predicted to be up-regulated. Conclusions The present MR analysis demonstrated the potential bidirectional causal relationships between gut microbiota and periodontitis. Our research provided fresh insights for the prevention and management of periodontitis. Future research is required to support the finding of our current study
