Interplay between telecommunications and face-to-face interactions - a study using mobile phone data

In this study we analyze one year of anonymized telecommunications data for over one million customers from a large European cellphone operator, and we investigate the relationship between people's calls and their physical location. We discover that more than 90% of users who have called each other have also shared the same space (cell tower), even if they live far apart. Moreover, we find that close to 70% of users who call each other frequently (at least once per month on average) have shared the same space at the same time - an instance that we call co-location. Co-locations appear indicative of coordination calls, which occur just before face-to-face meetings. Their number is highly predictable based on the amount of calls between two users and the distance between their home locations - suggesting a new way to quantify the interplay between telecommunications and face-to-face interactions

Making Space, Making Place: Digital Togetherness and the Redefinition of Migrant Identities Online

Immigrants have played a fundamental role in shaping the life and form of urban public spaces for generations. Their efforts, as many scholars have observed, mostly aimed at creating places of comfort in new and sometimes hostile receiving countries. In recent years, the combined contribution of the built environment and screen-based experiences have shaped migrants’ sense of community and belonging, thus making the concept of online community central to ideas about space and public life. Drawing upon a 3-year online ethnography, the article discusses to what extent new media constitute spaces of digital togetherness, where diasporic experiences and transnational identities are constructed and negotiated. It presents a transnational model of creative media consumption, which helps give insight as to how diasporas and ethnic minorities contribute to the transformation of public space in the Digital Age

Digital Food and foodways. How online food practices and narratives shape the Italian diaspora

The article discusses the role of online food practices and narratives in the formation of transnational identities and communities. Data has been collected in the framework of a doctoral research project undertaken by the author between 2009 and 2012 with a follow-up in 2014. The working hypothesis of this article is that the way Italians talk about food online and offline, the importance they give to ‘authentic’ food, and the way they share their love for Italian food with other members of the same diaspora reveal original insights into migrants’ personal and collective identities, their sense of belonging to the transnational community and processes of adjustment to a new place. Findings suggest that online culinary narratives and practices shape the Italian diaspora in unique ways, through the development of forms of virtual commensality and online mealtime socialization on Skype and by affecting intra and out-group relationships, thus working as elements of cultural identification and differentiation
