In the context of emergency remote teaching, this study proposes a conceptual model that examines (1) the relationship between perceived quality and learner satisfaction with an e-Learning service in pandemic situation and (2) to test the moderating role of co-production of this service on this relationship. The study was conducted among 338 Tunisian students who took online classes during the second wave of COVID-19. The research uses of structural equations method (AMOS 21) to test the direct relationship and the Hayes process for the moderation test. The results show that the direct relationship between perceived quality and online learner satisfaction is significant and positive and that this relationship is positively moderated by co-production. Practical implications have finally been identified in order to improve the success of online education especially in the case of a crisis.

Several reasons seem to justify the development trend of smart cities. Indeed, humanity is facing several challenges such as an increasing environmental impact, enormous difficulties in living in congested cities, and ever-increasing running costs. These challenges threaten the quality of life, especially in times of crisis, which has drawn attention to the relevance of using ICTs for governance purposes and has proliferated the awareness of stakeholders (authorities, citizens, civil society, etc.) to act in favor of the implementation of the mechanisms necessary for a new way of governing. This chapter presents the concept of smart cities and identifies the issues related to their development as well as the technologies that can intervene in the conversion of cities into smart and sustainable cities.

This chapter looks at the phenomenon of social media and its consequences on marketing and consumer behavior. To express an opinion, the authors first define the notion of “social media,” review their different types as well as the decisive moments that marked their history.
