    During the last decade, a growing number of disciplines dealing with innovation processes focused started to investigate the phenomenon of wireless community networks (WCN). These networks, now consolidated on a global level, represent an infrastructure that is entirely built and self-managed by citizens voluntarily cooperating to create a new model of digital communication other than the Internet and commercial services offered on the market by Internet Service Providers (ISP). WCN, therefore, represent an emblematic case to explore not only the technical aspects of more and more pervasive technologies within contemporary society, but also to focus on relations between social, political and techno-scientific dimensions supporting innovation practices. In fact, most recent experiences of WCN acquired a central role in redefining participation practices and political activism linked to digital media, and its forms of innovation. This paper, on the basis of data collected through a qualitative research on the origin and development of the main RWC in Italy, throws light upon the way in which community networks represent a peculiar form of social innovation, where a system of individuals – beyond traditional innovation and development institutions and on the basis of political values and beliefs – cooperate to originate a new infrastructure managing to endorse participation and social inclusion in the digital society. In doing this, the paper emphasizes the procedural dimension of social innovation as an emerging practice in the active cooperation among human beings and technologies, during which political visions, technical tools and social participation have an impact on each other and transform themselves

    Does \u2018bigger\u2019mean \u2018better\u2019? Pitfalls and shortcuts associated with big data for social research

    \u2018Big data is here to stay.\u2019 This key statement has a double value: is an assumption as well as the reason why a theoretical reflection is needed. Furthermore, Big data is something that is gaining visibility and success in social sciences even, overcoming the division between humanities and computer sciences. In this contribution some considerations on the presence and the certain persistence of Big data as a socio-technical assemblage will be outlined. Therefore, the intriguing opportunities for social research linked to such interaction between practices and technological development will be developed. However, despite a promissory rhetoric, fostered by several scholars since the birth of Big data as a labelled concept, some risks are just around the corner. The claims for the methodological power of bigger and bigger datasets, as well as increasing speed in analysis and data collection, are creating a real hype in social research. Peculiar attention is needed in order to avoid some pitfalls. These risks will be analysed for what concerns the validity of the research results \u2018obtained through Big data. After a pars distruens, this contribution will conclude with a pars construens; assuming the previous critiques, a mixed methods research design approach will be described as a general proposal with the objective of stimulating a debate on the integration of Big data in complex research projecting

    Whole-brain histogram and voxel-based analyses of apparent diffusion coefficient and magnetization transfer ratio in celiac disease, epilepsy, and cerebral calcifications syndrome

    BACKGROUND AND PURPOSE: Diffusion and magnetization transfer (MT) techniques have been applied to the investigation with MR of epilepsy and have revealed changes in patients with or without abnormalities on MR imaging. We hypothesized that also in the coeliac disease (CD), epilepsy and cerebral calcifications (CEC) syndrome diffusion and MT techniques could reveal brain abnormalities undetected by MR imaging and tentatively correlated to epilepsy. MATERIALS AND METHODS: Diffusion and MT weighted images were obtained in 10 patients with CEC, 8 patients with CD without epilepsy and 17 healthy volunteers. The whole brain apparent diffusion coefficient (ADC) and MT ratio (MTR) maps were analyzed with histograms and the Statistical Parametric Mapping 2 (SPM2) software. We employed the non-parametric Mann-Whitney U test to assess differences for ADC and MTR histogram metrics. Voxel by voxel comparison of the ADC and MTR maps was performed with 2 tails t-test corrected for multiple comparison. RESULTS: A significantly higher whole brain ADC value as compared to healthy controls was observed in CEC (P = 0.006) and CD (P = 0.01) patients. SPM2 showed bilateral areas of significantly decreased MTR in the parietal and temporal subcortical white matter (WM) in the CEC patients. CONCLUSION: Our study indicates that diffusion and MT techniques are also capable of revealing abnormalities undetected by MR imaging. In particular patients with CEC syndrome show an increase of the whole brain ADC histogram which is more pronounced than in patients with gluten intolerance. IN CEC patients, voxel-based analysis demonstrates a localized decrease of the MTR in the parieto-temporal subcortical WM

    Bottom-up Infrastructures: Aligning Politics and Technology in building a Wireless Community Network

    Get PDF
    Contemporary innovation in infrastructures is increasingly characterized by a close relationship between experts and lay people. This phenomenon has attracted the attention from a wide range of disciplines, including computer-supported cooperative work (CSCW), science and technology studies (S&TS), organization studies and participatory design (PD). Connecting to this broad area of research, the article presents a qualitative case study concerning the building and maintenance of a grassroots, bottom-up information infrastructure in Italy, defined as wireless community network (WCN). Methodologically, the research is based on qualitative interviews with participants to the WCN, ethnographic observations and document analysis. The aim of the article is to understand the alignment between the technical work implied in building this bottom-up infrastructure and the political and cultural frameworks that move people to participate to this project. Relying on the field of science & technology studies, and in particular on the notions of ‘inverse infrastructure’ and ‘research in the wild’, we disclose the WCN’s peculiar innovation trajectory, localized outside conventional spaces of research and development. Overall, the presentation of the qualitative and ethnographic data allows to point out a more general reflection on bottom-up infrastructures and to enrich the academic debate concerning bottom-up infrastructuring work and other similar typologies of collaborative design projects in the domain of infrastructures

    Motorcycling edgework: A practice theory perspective

    Get PDF
    In an effort to elucidate a deep understanding of the experience of dangerous motorcycling behaviour, we employ a practice theory perspective, drawing out connections between the practice, the consumption of objects, and the meanings surrounding both. Using the Biographical Narrative Interpretive Method (BNIM), we offer possible explanations as to why, in the face of troubling accident statistics, some motorcyclists continue to drive at excessive speeds. Narrative accounts portray dangerous motorcycling practice as autotelic, impulsive edgework, incorporating a strong connection between rider and machine, and embedded with symbolic, emotional values that cannot be accounted for by traditional rational choice models. Our findings allow for the potential of policymakers to address such motorcycling practice in ways more meaningful to those engaged in it

    Smartphones, streaming platforms, and the infrastructuring of digital music practices

    This chapter aims at advancing the intersections between science and technology studies (STS) and music studies by exploring some of these changes and, more specifically, those triggered by listeners\u2019 adoption of smartphone-based music streaming platforms like Spotify, YouTube, and Apple Music. Since the 1980s, the notion of infrastructure became a crucial entry point in STS for disentangling the intersection between technology, people, and shared practices. Historians and sociologists interested in technology explored the role of infrastructures to analyze the implications of large sociotechnical systems like electric power grids and telephone networks. A fruitful terrain of convergence between STS and media studies has emerged in the last few years as a consequence of the rise of digital platforms as crucial sociotechnical entities in contemporary society. In recent years, this interest has expanded, recognizing the crucial role of media platforms in reshaping a wide array of human activities and relations in several different fields
