Quantum computers are receiving more and more attention in the media, with the promise of becoming a revolution in computing and digital communications. Nowadays, we cannot know for sure whether this promise will be fulfilled, but it is possible to get an idea of where things could go. The objective of this article is to give a brief overview of quantum information technologies and their future possibilities. After a concise summary of the fundamentals of quantum computing and the current state of the technology, we make a review of the main areas in which the technology can lead to innovations that substantially improve the performance of the current technology. Finally, we point out some possible effects of the development of quantum computing in today’s economy and society.

Coinciding with the twenty-fifth anniversary celebration of the UOC, the following article aims to review the main transformations that the basic areas of business have undergone over the past two and a half decades. For this, we have enjoyed the participation of five female and five male professors in the studies of economy and business, who have given us some broad strokes on some of the main changes during this period and the challenges still to come. These topics are: leadership, decision-making, internationalization, digitalization, strategy, adaptation to change, ethics, corporate social responsibility, diversity, inclusion, business modal innovation, and finance.

Although those structures that we now call platforms have always been present in some sectors, it is from the establishment of the digital economy that they have come to play a leading role in our lives. Without understanding the mechanisms that govern the dynamics of digital platforms, which are different from those associated with the more traditional economy, it is difficult to understand many aspects of how today’s economy works. The objective of this article is to offer an introduction to the idea of platform and its characteristics. First, we review the general platform concept, the specificities of digital platforms and the particularities of their operation. Second, we describe the characteristics of the platforms that we consider more relevant in order to understand their social and economic effects. Finally, we choose three of these characteristics (the degree of digitisation, the openness in terms of access, provision, use and distribution, and their governance mechanisms) to develop a proposal for the classification of the platforms that we intend as a help to organise a little better our conception of the phenomenon. The classification scheme leads to the definition of different types of platforms that behave differently, as shown by the examples that we identify for each of them. We hope that our analysis will contribute to a better understanding of the paradigm shift brought about by the digitisation of the economy.

Social media play a relevant role as the basis to most processes related to information transfer as well as knowledge creation and transfer. In order to optimise those processes in organisations, knowledge management needs to take into account essential functions of social media. In this article, we describe some of the specific mechanisms by which a social media structure influences the effectiveness of information transfer and knowledge creation and transfer. Based on this, we put forward some considerations on the most suitable features of social media to meet organisational objectives. Knowledge management must be able to use existing social media and, if possible, to have those media adopt the most adequate structure.
