Purpose Previous studies have found that abusive supervision undermines employees' work motivation and attitudes, namely work engagement and job satisfaction. However, less is known about the mechanisms by which abusive supervision negatively relates to employees' work engagement and job satisfaction. Drawing on conservation of resources theory, this study examines employee silence as a mediating mechanism linking abusive supervision to employees' work engagement and job satisfaction. Design/methodology/approach Survey data were collected from a sample of 233 full-time employees of a large hotel service company in Taiwan. Structural equation modeling analyses were conducted to test the hypotheses. Findings The results showed that abusive supervision has a positive association with employee silence. Moreover, the results showed that employee silence mediates the negative associations of abusive supervision with employees' work engagement and job satisfaction. Originality/value This study advances our understanding of how abusive supervision results in poor work motivation and attitudes among employees. This contributes to the literature by identifying employee silence as a suitable mediating mechanism linking the negative associations of abusive supervision with employees' work engagement and job satisfaction.

A SET-state conductance change in a hafnium-oxide resistive switching memory cell due to repeated read events is investigated. We characterize a read-induced conductance change at different read voltages and SET-state conductance levels. Our result shows that the read-induced conductance degradation exhibits a two-stage evolution with the read pulse number. A SET-state conductance decreases slightly in the first stage and then follows inverse power-law dependence on the read number in the second stage. The power factor is an exponential function of a read voltage without regard to the SET-state conductance level, and the read pulse number at the transition of the two stages is related to a read voltage and conductance level. An analytical model to describe the two-stage conductance evolution is proposed. The parameters in the model are extracted from measurement data. Our model is verified by good agreement between the modeled and measured results in a wide range of read pulse number, read voltage, and SET-state conductance level.

We investigate the alignment properties of nematic liquid crystal on polyimide films bombarded by Ar ion beams with a small diode sputter type ion-beam source. The alignments of nematic liquid crystal 4'-n-pentyl-4-cyanobiphenyl (5CB) on treated polyimide surface are characterized by using polarizing optical microscope and conoscope. The polyimide surfaces are also studied by using atomic force microscope and x-ray photoemission spectroscopy. We have demonstrated that the polyimide surface treated by Ar ion beams can give both homogeneous and homeotropic alignments with the same ion beam apparatus but varying the energy of ion beam and the bombarding time.

Purpose The purpose of this study is to understand how ethical leadership and coworker ethical behavior will influence employee unethical pro-organizational behavior (UPB). In particular, the authors examine the mediating effect of moral disengagement on the relationship between ethical leadership and UPB and also investigate the moderating effect of coworker ethical behavior on the aforementioned effect. Design/methodology/approach Data were collected from 251 employee-coworker dyads from five organizations in Taiwan at two time points. Moderated mediation analysis was conducted to test the hypotheses. Findings The results show that moral disengagement mediates the relationship between ethical leadership and employee UPB. Moreover, the results show that coworker ethical behavior moderates the relationship between moral disengagement and employee UPB, as well as the mediated relationship between ethical leadership and employee UPB via moral disengagement. Specifically, both the moral disengagement-UPB relationship and the ethical leadership-moral disengagement-UPB relationship become weaker when coworker ethical behavior is high. Practical implications The results highlight the importance of creating an ethical work environment to get everyone behaving ethically in the workplace, because nurturing an ethical atmosphere in organizations will be useful in reducing the occurrence of UPB even for those who have high levels of moral disengagement. Originality/value This study shows that coworkers matter morally as much as leaders, demonstrating the importance of social influence from coworkers in organizations.

A device utilizes a plasma for a liquid crystal alignment. The alignment is processed in a vacuum chamber in a simple way. A general chemical vapor deposition is coordinated to reduce cost. The present invention is a novel contactless process avoiding particle contamination, residual static charge and scratch. And multiple are as of the present invention can be used for alignment.
