Even though existing studies have shown the positive effects of social network sites (SNSs) on learning behaviors and outcomes, how SNS can cause learners to develop negative perceptions about their learning activities is still understudied. Here we report a one-of-a-kind study that examines the negative impact of privacy concern on students’ learning behaviors online while using SNSs. Based on the stimulus-organism-response (SOR) paradigm, our study focuses on how privacy concern develops knowledge hiding perceptions of the learners, thereby affecting their online collaboration. Further, our study also explores the moderating role of perceived supervisory support between the relationship of privacy concern and knowledge hiding perceptions. Participants in the study were 282 students pursuing their studies in several higher educational institutions in China. Our findings show that two types of privacy concern (abuse of knowledge and unauthorized access to private data) can positively influence students’ knowledge hiding perception, which subsequently can negatively affect their participation in online collaborative learning. On the other hand, perceived supervisory support only moderates the relationship between privacy concern about abuse of knowledge and knowledge hiding perceptions. Based on these findings, we draw practice implications for supervisors and students in Universities.

The extant literature has focused on individuals’ knowledge-sharing behavior and its driving factors, which stimulate the knowledge transmission and exchange in organizations. However, little research has focused on factors that inhibit knowledge sharing and encourage individuals to hide their knowledge. Therefore, based on social exchange and displaced aggression theories, the study proposed and checked a model that examined the effect of abusive supervision on knowledge hiding (KH) via a psychological contract breach (PCB). The Psychological ownership was regarded as a boundary condition on abusive supervision and KH relationship. Using a time-lagged method, we recruited 344 full-time employees enrolled in an executive development program in a large university in China. The findings show that PCB mediates the association between abusive supervision and KH. Similarly, psychological ownership moderates the association between abusive supervision and KH. Employees with high psychological ownership minimized the effect of abusive supervision on KH. Based on study findings, contributions to theory and practice, limitations, and future directions are discussed.

Climate change poses a huge threat. Social networking sites (SNSs) have become sources of human–environment interactions and shaped the societal perception of climate change and its effect on society. This study, based on the extended parallel process model, aims to examine the effect of exposure to climate change-related information on SNSs on the pro-environmental behaviors of individuals. The study examines the mediation effect of fear of victimization from climate change between the exposure to climate change-related information on SNSs and pro-environmental behaviors, including the moderation effect of attention deficit and decision-making self-efficacy with the help of appropriate instruments. A total sample of 406 reliable questionnaires were collected from students using SNSs in China, and data were analyzed through SPSS and AMOS. Results indicate that the exposure to climate change-related information on SNSs has a direct positive effect on users’ pro-environmental behaviors (β = 0.299, p < 0.01). Fear of victimization from climate change also mediates the relationship between exposure to climate change-related information on SNSs and pro-environmental behaviors (β = 0.149, SE = 0.029, p < 0.01). In addition, attention deficit moderates the relationship of exposure to climate change-related information on SNSs with fear of victimization from climate change (β = −0.090, p ≤ 0.01) and pro-environmental behaviors (β = −0.090, p ≤ 0.05). Similarly, the relationship between fear of victimization from climate change and pro-environmental behaviors is moderated by decision-making self-efficacy (β = 0.267, p ≤ 0.01). The findings offer implications for media organizations and government policy makers, who should post or spread environmental information through the most trustworthy media, with trustworthy sources, in an effective manner, and without exaggerated adverse impacts.

Grounding our research in social exchange theory and the conservation of resources perspective, we hypothesized a model that examines the effects of servant leadership (SL) on employees' workplace thriving via agentic work behaviors. To clarify the effects, employee core self-evaluations (CSEs) were investigated to determine boundary conditions on the relationship between SL and thriving. Data were collected at three points in time from 260 professionals across diverse functional backgrounds and industries. The analysis results confirmed an indirect effect from SL to workplace thriving via agentic work behaviors. Importantly, the moderation results demonstrated that the relationship between SL and workplace thriving is stronger when individuals have high CSEs. Implications for theory and practice are discussed.
