Purpose The purpose of this paper is to study the effects of social media usage on four knowledge creation processes, namely socialisation, externalisation, combination and internalisation, and innovation in small and medium enterprises (SMEs). Design/methodology/approach A sample of 96 SMEs has been used to gather data through a standardised questionnaire and test the hypotheses through OLS regression models. Findings The results indicate that social media influence positively three out of four knowledge creation processes and that they help to foster the innovation process. Originality/value From a theoretical perspective, the study contributes to literature considering a specific digital tool and its effect on knowledge creation and innovation. In fact, a few studies have considered the impact of social media usage on other variables, such as ROI and productivity, but never on knowledge creation and innovation through a quantitative study. From a managerial perspective, the research suggests managers to implement and involve social media within business and innovation processes.

Purpose The purpose of this paper is to analyse a sustainable business model (SBM) implemented by an Alternative Food Network (AFN), namely the Italian Food Assembly, with the goal of exploring its drivers of success and explaining how it can contribute to enhance sustainable and anti-consumption behaviours. This research aims at combining principles from both SBM innovation and user-driven anti-consumption and well-being habits, in order to develop more successful, comprehensive and community-centred sustainable value propositions. Design/methodology/approach Given the research goal, an exploratory case study was prepared where multiple sources of data were employed, namely in-depth interviews, participant observation, focus groups and document analysis. Findings In the light of the Bocken et al. (2014) framework, this paper provides evidence on the implementation of an AFN where it is possible to observe a strong sharing of knowledge regarding sustainable consumption behaviours and an effective dissemination of best practices between members. The authors developed four propositions that support the creation of a sustainable food supply chain, laying the foundation for spreading consumer behaviours and motivations so that they become more sustainable in their consumption habits. Research limitations/implications Even though the case study is very rich in the amount of data gathered, it cannot be generalised. Further research will overcome this limitation by adding more cases within a comparative approach and through a quantitative methodology. Originality/value It adds value to recent literature and practice by focussing on how networks of producers, consumers and other actors could act to improve food anti-consumption behaviours, by embodying alternatives to conventional food systems.

This paper presents a literature review of humancomputer interaction works on wearable systems for sports. We selected a corpus of 57 papers and analyzed them through the grounded theory for literature review approach. We identified five themes across the papers: the different research perspectives, the type of sports and sportspeople, the roles of wearables in sports, their wearability, and the different types of feedback. These themes helped us in delineating opportunities for future research: the investigation of different form factors and types of feedback; the consideration of different sportspeople and collaborative tasks; the need of pushing the boundaries of the sports domain; the exploration of the evolution of sports; the interconnection of different devices; and the increase of methodological rigor.

The concept of Industry 4.0 has been mainly addressed by the current literature from a technological perspective, overlooking the organisational and even ethical challenges related to this recent paradigm. In order to become ‘4.0 compliant’, an enterprise must adapt its organisation and business approaches, and these changes may lead to a significant impact on sustainability. Therefore, we performed a systematic literature review to investigate the most recent Industry 4.0 research streams by adopting a multi-perspective approach. This analysis led to collect insights on the key traits of an Enterprise 4.0: integration, decomposed hierarchy, flexibility, and autonomy. Each of these keywords involves work environments, business and organisational models, and educational approaches, which constitute the key traits of the novel framework proposed in this study.

Technological advances in wearable computing are changing the sports domain. A variety of Personal Informatics (PI) tools are starting to provide support and improve athletes' performance in many sports. In this paper, we interviewed 20 amateur and elite athletes of different disciplines, using an array of PI devices, to explore how sports, as well as athletes' experience, are affected by such instruments. We discovered that amateur athletes present different patterns of usage compared to elite ones. Moreover, we found that elite athletes make sense of their data by exploiting the knowledge they have about their own body and sport practice. We then proposed four considerations for design that we believe should be explored in the future, to reflect on how self-tracking is changing our perspective on sports, and, by and large, on our everyday life. • Human-centered computing➝ Human computer interaction (HCI)
