Purpose This study aims to investigate the differential roles of self-esteem and co-rumination in the mediated relationship between abusive supervision and knowledge hiding via psychological safety. Design/methodology/approach The study used a three-wave time-lagged design and data were collected from 388 full-time employees in India. Findings The results show that psychological safety mediated the impact abusive supervision had on knowledge hiding. Further, this impact was weakened by higher self-esteem as employees with higher self-esteem were less affected by the impact of abusive supervision on psychological safety and knowledge hiding; but this impact was amplified by more co-rumination as employees who co-ruminated more were also more affected by abusive supervision in psychological safety and knowledge hiding. Research limitations/implications A cross-sectional design and the use of self-reported questionnaires are a few limitations of this study. Originality/value This study took a purposeful deviation from the traditional path of organizational justice to the study of abusive supervision and psychological safety and endeavored an alternate route, one of resource conservation. Further, employees have diverse reasons that heighten or dampen their inclination to hide knowledge from others in the workplace. The study examines co-rumination and self-esteem as possible boundary conditions.

PurposeThe purpose of this study is to examine the mediating role of perceived procedural justice and interactional justice on the relationship between moral leadership and the four psychological empowerment dimensions manifested in individuals' perceptions of meaning, competence, self‐determination, and impact.Design/methodology/approachData from 241 subordinates, who reported to 110 supervisors, were collected from clothing companies in southern mainland China. The subordinates responded to a self‐report survey, which consisted of the variables of interest. Because of the nature of nested data, hierarchical linear regression (HLM 6.0) was used for analysis.FindingsA fully mediated model of perceived justice was supported. Procedural justice and interactional justice were found to be differentially associated with the elements of psychological empowerment. Specifically, while perceived procedural justice accounted for more unique variance in the empowerment facets of meaning, competence, and impact, perceived interactional justice accounted for more unique variance in the facet of self‐determination.Originality/valueThis study contributes to the literature by first examining the relationships among moral leadership, two types of perceived justice, and the four empowerment dimensions in the Chinese context. A detailed discussion of the implication for both researchers and practitioners is also provided.

With the global spread of the Coronavirus epidemic, search engine data can be a practical tool for decision-makers to understand the epidemic's trends. This article uses trend analysis data from the Baidu search engine, the most widely used in China, to analyze the public's attention to the epidemic and the demand for N95 masks and other anti-epidemic materials and information. This kind of analysis has become an important part of information epidemiology. We have analyzed the use of the keywords “Coronavirus epidemic,” “N95 mask,” and “Wuhan epidemic” to judge whether the introduction of real-time search data has improved the efficiency of the Coronavirus epidemic prediction model. In general, the introduction of the Baidu index, whether in-sample or out-of-sample, significantly improves the prediction efficiency of the model.
