As of August 18 Bas Hofstra works as a Postdoctoral Research Fellow at Stanford University. You can reach him at bhofstra@stanford.edu.

 

Dissertation: The structure of social networks is crucial for obtaining social support, for meaningful connections to unknown social groups, and to overcome prejudice. Yet, we know little about the structure of social networks beyond those contacts that stand closest to us. This lack of knowledge results from a survey-research tradition in which solely strong social ties are mapped. This dissertation overcomes this issue by embracing a new feature of contemporary social life: the fact that individuals overwhelmingly maintain their social relationships online. The “digital footprints” of interactions left online enable scholars to test old and new theories on the structure of social networks in innovative ways. In this spirit, the goal of this dissertation is to understand the structure of online social networks for new insights into the structure of social networks in general. What are the theoretical and empirical promises and pitfalls of such a study? Bas Hofstra answers these questions through five empirical chapters in which he links offline survey data on Dutch adolescents with online network data from Facebook.

Dissertation: Online Social Networks: Essays on Membership, Privacy, and Structure

The structure of social networks is crucial for obtaining social support, for meaningful connections to unknown social groups, and to overcome prejudice. Yet, we know little about the structure of social networks beyond those contacts that stand closest to us. This lack of knowledge results from a survey-research tradition in which solely strong social ties are mapped. This dissertation overcomes this issue by embracing a new feature of contemporary social life: the fact that individuals overwhelmingly maintain their social relationships online. The “digital footprints” of interactions left online enable scholars to test old and new theories on the structure of social networks in innovative ways. In this spirit, the goal of this dissertation is to understand the structure of online social networks for new insights into the structure of social networks in general. What are the theoretical and empirical promises and pitfalls of such a study? Bas Hofstra answers these questions through five empirical chapters in which he links offline survey data on Dutch adolescents with online network data from Facebook.

Learning in social networks: selecting profitable choices among alternatives of uncertain profitability in varying networks

We generate computer-simulated data to derive hypotheses about the effect of network positions and network structures on making the most profitable choices. Thereafter, we establish an experimental design in the same parameter space as our computer simulation to empirically test these hypotheses. From these experimental data we see that on the micro-level, degree and closeness centrality have a positive effect on making profitable choices, while betweenness centrality has no effect. On the macro level, we see that density has a positive effect on making profitable choices, while we did not find an effect of centralization.

Data collection

Hofstra coordinates the data collection of the Children of Immigrants Longitudinal Survey in the Netherlands Wave 4 – Wave 7. In addition, he coordinates the data collection/mining of online social networks to enrich these data. This has resulted in two data sets: the Hyves Data Summer 2012 (HDS12) and the Facebook Data Summer 2014 (FDS14).
