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.

Digital technologies are widely recognised as crucial for promoting the circular economy in industry. However, there still needs for clearer guidance for industrial practitioners on properly using digital technologies to support the implementation of the circular economy. Further efforts are needed to characterise such a relationship better. This work conducts a systematic literature review aimed at understanding the nature and scope of the relationship by examining current knowledge at the intersection of the two domains, i.e. digital technologies and the circular economy. Specifically, the analysis focuses on identifying moderators and mediators of this relationship. About the former, the study discusses the relevance of management commitment, competencies, stakeholders and contextual factors; concerning the latter, the study discusses the relevance of supply chain integration and collaboration and examines in more detail the role of digital‐enabled dynamic capabilities, given their promising relevance in the current debate. Based on the review, a research agenda is proposed with suggestions for future research directions on the relationship between digital technologies and the circular economy.

For some years now, scholars have been exploring some of the negative consequences for the psychosocial well-being of users that the rapid incorporation of smartphones into our lives has caused. Most of the empirical studies to date are cross-sectional and are carried out with participants from convenience samples, which has been a limitation in this field. In this study, we evaluated the evolution over three years of smartphone addiction and social support in 241 Spanish users of a representative national sample. The results of the analysis of latent growth and growth mixture modeling indicate that both trajectories are interconnected: the more addiction decreases, the more social support increases. In addition, high levels of addiction and relatively low levels of support remained stable over time in a group of users. Users of this high-addiction group would represent a trend in the digital society characterized by higher rates of loneliness and technological dependence. Desde hace algunos años los estudiosos han venido explorando algunas de las consecuencias negativas que la rápida incorporación de los teléfonos inteligentes en nuestra vida ha tenido en el bienestar psicosocial de los usuarios. La mayoría de los estudios empíricos hasta la fecha son de corte transversal y se realizan con participantes de muestras de conveniencia, lo que ha sido una limitación en este campo. En este estudio evaluamos la evolución durante tres años de la adicción a teléfonos inteligentes y el apoyo social en 241 usuarios españoles de una muestra nacional representativa. Los resultados del análisis del modelado del crecimiento y modelado de la mezcla de crecimiento indican que ambas trayectorias están interconectadas: a medida que aumenta la adicción aumenta el apoyo social. Además, los altos niveles de adicción y los niveles relativamente bajos de apoyo se mantuvieron estables en el tiempo en un grupo de usuarios. Los usuarios de este grupo de elevada adicción representarían una tendencia en la sociedad digital caracterizada por mayores índices de soledad y dependencia tecnológica.

Mobile devices such as smartphones and tablets become more present in our lives every day. Most of these devices use the Android operating system (O.S.), becoming the most popular O.S. for mobile devices. For these devices, there is a huge offer of application software that provides answers to users’ different needs. This study aims to analyse how combinations of personality factors, sociodemographic variables and Internet use influence the adoption of productivity mobile apps by workers. To achieve this, a combination of these variables is analysed using fuzzy set Qualitative Comparative Analysis (fsQCA.) that allows us to analyse complex complementarities among factors. The results show the importance of distinct personality traits – extraversion and agreeableness – to understand the adoption of these services. Our study also provides relevant insight for software developers to target segments interested in the use of productivity software in their mobile devices.

(1) Background: This paper combines lifestyle-routine activities (L-RAT) and self-control (SCT) theories along with the literature on smartphone addiction in a joint model that addresses the multiple vulnerabilities that make the smartphone user a potential victim of cybercrime. This model, which we call the dual vulnerability model of cybercrime victimization, was subjected to empirical testing on a nationally representative sample of smartphone users. (2) Methods: Data from 2837 participants from a nationally representative sample of Spanish smartphone users were modeled using Mplus causal modeling software. (3) Results: The results of the study confirm the predictions of L-RAT and SCT in explaining cybercrime victimization (higher cybercrime victimization under conditions of high exposure, proximity, and suitability, relative absence of capable guardian, and low self-control). A significant effect of smartphone addiction on cybercrime victimization was also observed above and beyond L-RAT and SCT predictors. (4) Conclusions: The potential victim of cybercrime presents a double vulnerability, on the one hand, those identified by criminological theories such as L-RAT and SCT, and on the other hand, those derived from the deregulated-addicted use of the Internet access device (smartphone in our work).

Introducing an innovation does not end, but rather starts, with adoption. In fact, some innovations display network elements and require more than one firm to take them up in order to be successful and deliver the intended results. Such is the case of NDC (new distribution capability), an airline-fostered enhancement of the way air travel services are conveyed and distributed from carriers to travel agents. The promise behind NDC is that travel services will be sold more richly and within a more open and inclusive framework. We draw on the diffusion of innovations, institutional theory, and agency theory to review the determinants of adoption and its effects on performance for service providers. We use the International Air Transport Association (IATA) ticket database to establish the role that institutional pressure plays on innovation behaviours and firms’ results. We find that institutional pressure, not just innovation attributes, influence outcomes. Also, given each player's different incentives and the asymmetry of information, ticket sales are selectively distributed in ways that fit the agent and only occasionally the airline principal. Thus, we conclude that travel intermediaries assess outcomes wholistically and that the innovation's revenue uplift depends on such assessment.
