Servant leadership style has drawn much attention in the last decade to leadership studies on account of its focus on serving others first. Extant literature calls for a better understanding of the underlying mechanism for servant leadership to positively influence performance within an organization. We position servant leadership to contribute to firms’ sustainable performance, by empirically studying the mediating mechanism of bi-dimensional trust, namely affective and cognitive trust, between servant leadership and individual performance. Our data comprised of dyadic samples of 233 pairs of subordinates and their supervisors. The results from hierarchical linear model (HLM) for clustered data showed that servant leadership strongly predicted affective trust, organizational citizenship behaviors (OCBs), and task performance of subordinates; affective trust fully mediated servant leadership’s effect on task performance while partially mediates servant leadership’s effect on subordinates’ OCB. In contrast, cognitive trust did not mediate servant leadership’s effect on either OCB or task performance. These findings reveal the relevance of affective trust as the underlying mechanism which mediates and deciphers servant leadership into positive individual performance.

During uncertain situations, such as the COVID-19 partial lockdown, maintaining satisfactory levels of employee performance (EP) is an important area of concern for many organizations. The current study examines the relationship of work stress due to COVID-19 (COVID-19 STR) and EP. Using social exchange theory (SET), safety culture (SC) is presented as a moderator for stress and performance relationships. A sample of 213 bank employees was collected using a convenient sampling method. Data were analyzed using stepwise linear regression and PROCESS Macro by Hayes (2013). Results revealed that COVID-19 STR has a negative impact on task and contextual performance (CP) and a positive impact on adaptive performance (AP). Similarly, the prevalence of SC significantly moderates the stress and performance relationships.

The scientific community’s growing interest in green marketing research can be traced through the abundance of published literature on the topic. However, there is still a lack of a comprehensive and systematic research focusing on the evolution of this field. The main objective of this paper was to consolidate the state-of-the-art research on green marketing through a bibliometric study of articles published from 1977 to 2020, and to analyze and present the results from the perspective of growing trends in the field; productive and influential countries, institutions, authors, articles, and research journals; keywords; authorship patterns; and international collaborations. The study results indicate a gradual increase in green marketing research from 1977 to 2020, more so in the last five years. A total of 1025 scholarly documents were published in 634 journals during this period and listed in the Web of Science (WOS). The top 10 most productive countries were then analyzed. A great number of institutions from both developing countries (in terms of article count) and developed countries (in terms of citation scores), were compared. Finally, based on keywords and a three-factor analysis, it was concluded that green marketing, sustainability, sustainable development, environment marketing and sustainable marketing have attracted extensive attention during the past decade as keywords.
