Knowledge is considered to be an economic driver in today's economy. It has become a commodity, a resource that can be packed and transferred. The objective of this paper is to provide a comprehensive review of the scope, trends and major actors (firms, organizations, government, consultants, academia, etc.) in the development and use of methods to manage innovation in a knowledge‐driven economy. The paper identifies the main innovation management techniques (IMTs) aiming at the improvement of firm competitiveness by means of knowledge management. It will specifically focus on those IMTs for which knowledge is a relevant part of the innovation process. The research study, based on a survey at the European level, concludes that a knowledge‐driven economy affects the innovation process and approach. The traditional idea that innovation is based on research (technology‐push theory) and interaction between firms and other actors has been replaced by the current social network theory of innovation, where knowledge plays a crucial role in fostering innovation. Simultaneously, organizations in both public and private sectors have launched initiatives to develop methodologies and tools to support business innovation management. Higher education establishments, business schools and consulting companies are developing innovative and adequate methodologies and tools, while public authorities are designing and setting up education and training schemes aimed at disseminating best practices among all kinds of businesses.

In some countries, photovoltaic (PV) technology is at a stage of development at which it can compete with conventional electricity sources in terms of electricity generation costs, i.e., grid parity. A case in point is Germany, where the PV market has reached a mature stage, the policy support has scaled down and the diffusion rate of PV systems has declined. This development raises a fundamental question: what are the motives to adopt PV systems at grid parity? The point of departure for the relevant literature has been on the impact of policy support, adopters and, recently, local solar companies. However, less attention has been paid to the motivators for adoption at grid parity. This paper presents an in-depth analysis of the diffusion of PV systems, explaining the impact of policy measures, adopters and system suppliers. Anchored in an extensive and exploratory case study in Germany, we provide a context-specific explanation to the motivations to adopt PV systems at grid parity

Recent literature has suggested that smartphone addiction is negatively associated with users’ psychosocial well-being. Much of the research on this subject, however, is of a correlational nature, which has been pointed out as an important limitation that does not allow distinguishing the antecedents of the consequences. In this study, 416 smartphone users were followed for 1 year (three waves separated by 6 months each) to assess the relationship between smartphone addiction and social support. Cross-lagged model results indicated that social support predicts later addiction to the smartphone and that smartphone addiction decreases social support over time. Growth mixture model results indicated that the decrease in social support during the follow-up year was higher for users with greater smartphone addiction at the beginning of the study. Multivariate and univariate analyses of variance indicated that some personal characteristics of users (extroversion, neuroticism, and sensation-seeking) could affect the evolution of social support related to smartphone addiction. In general, these results suggest that the extensive use of a social communication technology such as the smartphone could have the paradoxical effect of diminishing the psychosocial well-being of its users.
