Purpose The purpose of this paper is twofold: first, the authors empirically examine the effect of the perceived values of mobile banking (MB) applications on customers’ e-trust, e-satisfaction and e-loyalty and second, the authors investigate the moderating role of customers’ age in the relationship between perceived value of MB and e-trust. Design/methodology/approach A survey was conducted on a sample of 361 Tunisian banks’ customers using mobile applications. Structural equation modeling method was performed to test the research hypotheses. Findings The results of this research revealed that quality, price and emotional perceived values’ dimensions of MB applications are predictors of customers’ e-trust. Within this spectrum, age acts as a moderator in these latter relationships. Findings also suggested that e-trust has positive effects on e-satisfaction and e-loyalty. Practical implications This paper presented a reading grid for bank marketers allowing them to identify the levers they must focus their efforts on so as to retain the customers using MB applications. It also permits them to identify the needs and values of three generation of customers, namely baby boomers, generation X and generation Y, so that they can offer better services for each group. Originality/value This paper sheds light on an innovative and unexplored topic in the literature. The authors broaden understanding of the relationship between the perceived values of MB applications, e-loyalty, e-trust and e-satisfaction. Research devoted to investigate these different links through an integrative model does exist, yet embryonic. This study also highlights differences between three group of customer, namely baby boomers, generation X and generation Y in terms of perceived values that builds their trust in the context of MB applications use.

PurposeThe objective of this research is to examine the mediating role of employees' well-being in the workplace in the relationship between the dimensions of social capital, namely structural, relational and cognitive social capital and knowledge sharing, as well as the moderating role of enterprise social networks between knowledge sharing and employees' well-being.Design/methodology/approachA quantitative approach was performed within a sample of 168 middle managers working in knowledge-intensive firms in Tunisia. The Partial Least Squares method was used to analyze the data collected.FindingsResults highlight the importance of the dimensions of social capital as a lever for boosting knowledge sharing. It also reveals that employees' well-being plays a mediating role in the link between structural and relational social capital and knowledge sharing. Moreover, findings show that while enterprise social networks use does not moderate the relationship between employees' well-being and knowledge sharing, it has a positive and significant effect on knowledge sharing.Originality/valueOn the basis of a socio-technical perspective of knowledge management, this research pioneers the examination of the mediating effect of employees' well-being in the link between dimensions of social capital and knowledge sharing and the moderating role of enterprise social networks use within knowledge-intensive firms. Findings of this study may help managers of knowledge-intensive firms in boosting knowledge sharing within organizations, in improving knowledge workers' well-being and thus in motivating and retaining these talented employees.

Purpose The purpose of this study is to examine the effect of the transformational and transactional leadership styles and its sub-dimensions on exploitative and exploratory innovations. The authors deepened the analysis by highlighting the contribution of ambidextrous leadership on ambidextrous innovation. Design/methodology/approach The conceptual model defined through a thorough review of the literature is tested empirically on a sample of 265 senior managers working in Tunisian knowledge-intensive firms (KIFs). A quantitative analysis is performed via a questionnaire. The analysis of the data collected is carried out using the partial least squares method. Findings Results show that exploratory innovation is linked to transformational leadership and in particular to individualized consideration, intellectual stimulation and inspirational motivation. Moreover, exploitative innovation is promoted by transformational and transactional leadership styles and particularly by attributed idealized influence and contingent rewards. Also, ambidextrous leadership affects positively ambidextrous innovation. Originality/value While little studies have investigated how the transformational and transactional leadership styles as constructs of second-order influence differently exploitative innovation and exploratory innovation, this research deepens the analysis by focusing on sub-dimensions of leadership styles that promote each type of innovation within KIFs. It also pioneers the investigation of the effect of ambidextrous leadership on ambidextrous innovation that has never been explored. This research provides important insights for leaders of KIFs and sheds the light on the key aspects of leadership that boost ambidextrous innovation.
