In an era marked by digital transformation and organisational complexity, multinational corporations (MNCs) strive to build flexible systems that can harness and share knowledge effectively across diverse cultural and geographic contexts. This study investigates the strategic role of organisational culture in enabling the adoption and utilisation of knowledge management systems (KMSs) and how this relationship influences knowledge sharing and organisational effectiveness. Drawing upon the Technology Acceptance and Denison’s cultural framework, this research positions organisational culture as a key driver of system flexibility, enhancing user perceptions of usefulness and ease of use, and thereby fostering greater engagement with KMSs. Survey data from 221 respondents across Europe and the Middle East were analysed using Partial Least Squares Structural Equation Modelling (PLS-SEM). The findings reveal that cultural adaptability, involvement, and mission significantly impact KMSs usage and knowledge sharing, which are critical for organisational agility and sustained performance. This study contributes to the literature on flexible systems management by demonstrating how culturally embedded knowledge practices enhance technological adoption and strategic responsiveness. It offers practical insights for global firms seeking to develop adaptive knowledge infrastructures that support innovation, collaboration, and resilience in dynamic international environments.

This paper aimed to assess the effect of the cryptocurrency market on firms’ market value, especially on the sectoral level, in Africa. To reach the study’s main goal, the authors adopted the Panel-Corrected Standard Errors (PCSEs) and Panel Double-Clustered Standard Errors (PDCSEs). Using firm-level data, the results of this study can be summarized as follows: (a) The cryptocurrency market hurts the firm market value in Africa. (b) The firms operating across different sectors respond disproportionally to the cryptocurrency market. For instance, the sectors that offer low returns in Africa (industrial, energy, financial) negatively respond to the cryptocurrency market, while the sectors that offer high returns (real estate and information technology) are not significantly affected. (c) The cryptocurrency market has a perverse effect on less experienced and highly indebted firms. (d) The consistent policies of governments to ban cryptocurrency do not work efficiently.
