Purpose Drawing on uncertainty management theory, the purpose of this paper is to propose that experiencing the authoritarian leadership (AL) will weaken followers’ self-efficacy, which induces their compulsory citizenship behaviors (CCBs), defined as workers’ unwilling prosocial behaviors in helping colleagues. Design/methodology/approach Survey/regression: data collected from Taiwanese workers supports the proposal. Findings The results not only support the proposal but also show that supervisor support will exacerbate the negative effect of AL with workers’ self-efficacy. Further, workers’ political skill will attenuate the above relationship. Originality/value This study complements scholarly knowledge about how AL, supervisor support, and political skill together influence workers’ self-efficacy, which then induces CCBs. The findings also remind supervisors not to offer support while at the same time demonstrating an AL style.

Previous studies examining diverse team knowledge resources and individual members' performance largely follow the information perspective and propose that team informational diversity may help individuals perform better. Unlike previous authors, we integrate arguments from subgroup theory and the social categorization perspective to argue that when a person works in a cross‐functional team, perceiving differences in expertize with other teammates may decrease the person's social exchange relationship with colleagues, that is, team‐member exchange/TMX. Thus, perceived differences in expertize with other teammates may reduce TMX and, in turn, weaken individual task performance. Moreover, team members' social exchange relationship with the leader/LMX may offset the individual's deficiency in TMX to complement the person's task performance. We examine dyadic data collected from Taiwanese worker‐supervisor pairs and find support for our hypotheses.

hypertrophy), or with elements of CKD-MBD (Vitamin D, iPTH, Ca, P, CaXP) we found no correlation. sKlotho showed a positive correlation with hemodialysis efficiency (eKTV) (r¼0.26, p-0.04), but no correlation with hemodialysis duration. When we classified patients according to median sKlotho level, we found out that patients with sKlotho> 333.398 pg/ml had significantly higher level of hemoglobin (11.2 vs. 10.6 g/dl, p¼0.017). Patients with higher levels of sKlotho showed a decreased risk of mortality, however not statistically significant. We found a higher risk of all cause mortality in patients with diabetes mellitus (OR 6.9, 95% CI-1.6924 to 28.1469, p¼0.007) and with left ventricular hypertrophy (OR 12.4, 95% CI-1.5135 to 102.9073, p¼0.01). Conclusions: In our study, higher levels of sKlotho were associated to a better controlled anemia, a better hemodialysis efficiency, the absence of signs of coronary heart disease on ECG, but not with an increased 2 year survival in hemodialysis patients.
