Sharing Networks 2017: pen-and-paper fieldwork in a big data world

I’m excited to report that earlier this month, I ran the second wave of data collection for our Sharing Networks research project at OuiShare Fest 2017!

Publicizing the survey at OuiShare Fest 2017

To understand how people form and reinforce face-to-face network ties at such an event, I fielded a questionnaire with the help of a committed and effective team of co-researchers. It is a “name generator” asking respondents to name those they knew before the OuiShare Fest, and met again  there (“old frields”); and those they met during the event for the first time (“new contacts”). Participants then have to choose those among their “old” and “new” contacts, that they would like to contact again in future for joint projects or collaborations.

Interestingly, my good old pen-and-paper questionnaire still gives a lot of insight that digital data from social media cannot provide – just like a highly computer literate community such as this feels the need to meet physically in one place every year for a few days. Like trade fairs that flourish even more in the internet era, the OuiShare Fest gathers more participants at each edition. They meet in person there, which is why they are to be invited to respond in person too.

Sharing Networks study 2017: Moving online!

I’m so excited that earlier this month, I ran the second wave of data collection for my Sharing Networks research project at OuiShare Fest 2017!

The Sharing Networks 2017 survey team (incomplete).

The study aims to map the collaborative economy community that gathers at OuiShare Fest, looking at how people network and how this fosters the emergence of new trends and topics.

During the event, a small team of committed and effective co-researchers helped me interview participants. We used a questionnaire with a “name generator” format, typically used in social network analysis to elicit people’s connections and reconstitute their social environment.

Specifically, we asked respondents to name people they knew before the

OuiShare Fest, and met again there (“old friends”), and people they met during the Fest for the first time (“new contacts”). Then we asked them to choose, from among the “old” and “new” they had named, those they would like to contact again with soon, for example for joint projects or collaborations.

I am very happy with the result: 160 completed interviews over three half-days! But it is still not enough: participants to the Fest were much more numerous than that, and in social network analysis, it is well-known that sampling is insufficient, and one needs to get as close to exhaustiveness as possible.

Therefore, for those OuiShare Fest 2017 participants that we did not manage to interview, there is now an opportunity to complete the questionnaire online.

If you were at the Fest and we did not talk to you, please do participate now! It takes less than 8 minutes, and you will help the research team as well as the organization of the Fest.

Many thanks to the team of co-researchers who helped me, the OuiShare team members who supported us, and all respondents.

The “pro-ana” phenomenon: Eating disorders and social networks

proanaA new book is just out, co-authored by myself and Antonio A. Casilli: a synthesis of our 5-odd years research on the self-styled internet communities, blogs and forums of persons with eating disorders. For years, lively controversies have surrounded these websites, where users express their distress without filters and go as far as to describe their crises, their vomiting and their desire for an impossibly thin body – thereby earning from the media a reputation for “promoting anorexia” (shortened as “pro-ana”). In France, an attempt to outlaw these online spaces last year was unsuccessful, not least because of our active resistance to it.

The book tells the story of our discovery of these communities, their members, their daily lives and their social networks. Ours was the first study to go beyond just contents, and discover the social environments in which they are embedded. We explored the social networks (not only online relationships, but day-to-day interactions at school or work, in the family, and among friends) of internet users with eating disorders, and related them to their health. The results defy received wisdom – and explain why banning these websites is not the right solution.

Internet deviance or public health budget cuts?

It turns out that “pro-ana” is less a form of internet deviance than a sign of more general problems with health systems. Joining these online communities is a way to address, albeit partially and imperfectly, the perceived shortcomings of healthcare services. Internet presence is all the more remarkable for those who live in “medical deserts” with more than an hour drive to the nearest surgery or hospital. At the time of the survey in France, a number of areas lacked specialist services for eating disorder sufferers.

These people do not always aim to refute medical norms. Rather, they seek support for everyday life, after and beyond hospitalisation. These websites offer them an additional space for socialisation, where they form bonds of solidarity and mutual aid. Ultimately, the paradoxical behaviours observed online are the result of underfunded health systems and cuts in public budgets, that impose pressure on patients. The new model of the ‘active patient’, informed and proactive, may have unexpected consequences.


A niche phenomenon with wider repercussions

In this sense, “pro-ana” websites are not just a niche phenomenon, but a prism through which we can read broader societal issues: our present obsession with body image, our changing relationships with medical authorities, the crisis and deficit of our publich health systems, as well as the growing restrictions to our freedom of expression online.

Visualization in mixed-methods research on social networks

The journal Sociological Research Online has just published (31 May 2016) a special section on “Visualization in Mixed-Methods Research on Social Networks”, guest edited by Alessio D’Angelo, Louise Ryan and myself.

Figure 1 – Tubaro, Ryan & D’Angelo

The five papers in this peer-reviewed special issue explore the potential of visual tools to accompany qualitative and mixed-methods research. Visualization can support data collection, analysis and presentation of results; it can be used for personal or complete networks; it can be paper-and-pencil or computer-based. Overall, visualization helps to jointly understand network contents and network structures.

The special issue is freely accessible from all commercial (non-academic) internet providers.

International Program in Survey and Data Science

A new, master’s level programme of study in Survey and Data Science is to be offered jointly by the University of Mannheim, the University of Maryland, the University of Michigan, and Westat. Applications for the first delivery are accepted until 3 January, for a start in Spring 2016. Prospective students are professionals with a first degree, at least one year of work experience, and some background in statistics or applied mathematics. All courses are delivered in English, fully online, to small classes (it’s not a MOOC!). Tuition is free, thank to support from German public funds at least for the first few cohorts.

What is most interesting about this master is its twofold core, involving both more classical survey methodology and today’s trendy data science. Fundamental changes in the nature of data, their availability, the way in which they are collected, integrated, and disseminated, have found many professionals unprepared. These changes are partly due to “big” data from the internet and digital devices becoming increasingly predominant relative to “small” data from surveys. Big data offer the benefit of fast, low-cost access to an unprecedented wealth of informational resources, but also bring challenges as these are “found” rather than “designed” data: less structured, less representative, less well documented (if at all…). In part, these changes are also due to the world of surveys changing internally, with new technical challenges (regarding for example data preservation, in a world of pre-programmed digital obsolescence), legislative issues (such as those triggered by greater awareness of privacy protection), increased demand by multiple users, and a growing need to merge surveys and data from other (such as business and administrative) sources. It is therefore necessary, as the promoters of this new study programme rightly recognize, to prepare students for the challenges of working both with designed data from surveys and with big data.

It will be interesting to see how data science, statistics, and social science / survey methodology feed into each other and support each other (or fail to do so…). There is still work to be done to develop techniques for analyzing data that allow us to gain insights more thoroughly, not just more quickly, and help us develop solid theories, rather than just uncovering new relationships that might eventually turn out to be spurious.

The power of survey data: Eurostat Users’ Conference

survey3In the age of big data, social surveys haven’t lost their appeal and interest. Surveys are the instrument through which governments, for a long time, have gathered information on their population and economy to inform their choices. Interestingly, surveys conducted by, or for, governments are the best in terms of quality and coverage: because significant resources are invested in their design and realization, and especially because participation can be made compulsory by law (they are “official”), their sampling strategies are excellent and their response rates are extremely high. (Indeed, official government surveys are practically the only case in which the “random sampling” principles taught in theoretical statistics courses are actually applied). In short, these are the best “small data” available — and their qualities make them superior to many a (usually messy) big data collection. It is for this reason that surveys from official statistics have always been in high demand by social researchers.

“Pro” ana? Sociability and support in eating disorder online communities

This article was first published on Discover Society, November 2014.

Last June, a group of Italian MPs proposed jail terms and fines for authors of so-called “pro-ana” (anorexia) and “pro-mia” (bulimia) websites. These are self-styled online communities on eating disorders which are viewed as promoting extreme dieting and unhealthy eating practices. France and the United Kingdom preceded Italy’s attempt to pass restrictive legislation as far back as 2008-9, and many internet service providers also endeavoured to ban these contents.

But the potential spread of health-hazardous behaviours is probably only one side of the coin, and these websites might also channel health-enhancing assistance, advice, and support (Yeshua-Katz & Martins 2013). In fact a closer look reveals that website users carefully manage their online socialisation to address their health challenges. Online social spaces enable discussion around the illness and constitute a complement, albeit an admittedly imperfect one, to formal healthcare services. There is no rejection of standard health norms in the name of some extreme ideal of thinness but rather a need – or perhaps, a cry – for extra support.

A social science approach brings out these results. The effect of web interactions on health does not only depend on website contents, but also on how people actually use them, share them, and access resources through them. The social, rather than just clinical dimension of eating disorders, recognized long before the advent of the web (Bell 1985, Orbach 1978), becomes ever more relevant in the current context and calls for a more comprehensive view of the “ana” and “mia” social universe.
