Purpose The aim of this paper is to highlight the impact of distributed leadership (DL) on exploitative and exploratory innovations through the mediating effects of organizational trust (OT) and tacit and explicit knowledge sharing (KS). Design/methodology/approach Focusing on a quantitative approach, an empirical study was performed within a sample of information and communication technology Tunisian firms. The data collected was analyzed through the Partial Least Squares (PLS) method. Findings Findings revealed that DL is a driver of tacit and explicit KS, and exploitative and exploratory innovations. It also highlighted that tacit KS is associated with these two types of innovation. In this line, results showed that tacit KS plays a mediating effect between DL and exploitative and exploratory innovations. Moreover, our research highlighted that DL has a positive impact on OT that in turn boosts tacit and explicit KS. Originality/value This paper investigates the links between DL and exploitative and exploratory innovations within knowledge intensive firms (KIFs) that have never been studied in the literature within the context of business firms. This paper pioneers the examination of the mediating roles of explicit and tacit KS and OT in these links as well. This paper highlights the importance of DL for KIFs and sheds the light on how this collectivist approach of leadership creates an atmosphere of trust and fosters tacit and explicit KS to boost exploitative and exploratory innovations.

The frequent world changes raised by globalization, new technology development, and the increase in migration movements have generated an immensely diversified workforce. To face these challenges, managers started to seek the best strategies to effectively run this mixed environment and implement the leading diversity management policies for human resource management sustainability, which is also considered as very constructive in boosting employees’ performance, motivation, satisfaction, as well as their work engagement. Consistently, this paper examines the impact of service companies’ diversity management systems on employees’ engagement and the moderating role of organizational trust and job insecurity in that relationship. As we opted for a quantitative study, we managed a survey based on a questionnaire dedicated to 580 employees working in Hungarian companies, specializing in Marketing, Management consulting, IT, and logistics services, to effectively assess the hypothesis concluded from the literature review. With the use of structural equation modeling (SEM) as a data analysis tool, our findings reveal that diversity management has a positive significant effect on Employees’ engagement and that organizational trust and job insecurity truly and significantly mediate that association. Along with social exchange theory, our research contributes to affirming that by implementing proper diversity management practices and by ensuring a trustworthy environment and outstanding work conditions, managers are constructively able to assist their employees, raise their involvement, and minimize the level of job insecurities.

The twenty-first century has been full of fundamental changes in consumers’ behavior patterns, especially with the use of diverse social media knowledge-sharing platforms. Therefore, companies have highlighted the significance of knowledge sharing and the importance of social network use in purchasing processes. Accordingly, his paper tries to reveal how consumer purchase behavior (CPB) can be affected by consumer knowledge sharing behavior (CKSB) and the moderating role played by value co-creation dimensions, which are citizenship behavior (CB) and participation behavior (PB), within a sustainable e-commerce field. To test our hypotheses deducted from the literature review, we opted for the PLS-SEM method. We also employed other innovative approaches, such as the IPMA matrix, MAICOM test, FIMIX approach, and CTA analysis, to evaluate the outer and inner model. Our statistical population covered individuals living in Hungary with at least one online purchase involvement. We distributed the questionnaire via various online platforms and, finally, 433 completed questionnaires were prepared for analysis. The results showed that CPB, CB, and PB are positively influenced by the CKSB. However, the link between CPB and CB was not confirmed. As for the moderating role of gender, the permutation test was applied to compare male and female groups and see the difference between them. With a focus on CKSB, this study contributes to the success of international marketing strategies to attain higher competitive advantages.

In the context of organizational change, employees can have different reactions, where some of them accept and engage with it, and others completely refuse and resist it. Hence, companies should permanently settle for the best and introduce a fruitful leadership style along with a good change management strategy to ensure the company’s prolonged survival and prosperity. This investigation aims to examine the influence of transformational leadership on employees’ affective commitment and intention to support change. Both were chosen to constitute the main dimensions of employees’ reactions toward organizational change and highlight the importance of organizational trust as a mediator in that correlation. To confirm the hypotheses subtracted from the literature review, a quantitative study was managed by a survey devoted to 428 employees working for diverse service companies in Hungary and going through different change cases.Structural equation modeling (SEM) was then applied to hold out the favorable findings, which reveal that transformational leadership is a booster for employees’ intention to support change but not for affective commitment. It was also found that organizational trust firmly mediates the relationship between transformational leadership and employees’ reaction to change. This statement justifies that both transformational leadership and organizational trust are able to reduce change complexity and lead to its acceptance, openness, and support.
