Profiling the European citizen: why today's democracy needs to look harder at the negative potential of new technology than at its positive potential

Semantic discovery and reuse of business process patterns

Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

The role of offline ties in online communities : the case of Wikipedia

This thesis investigates the role of offline ties in online communities, taking the online encyclopaedia Wikipedia as an example. It uses publicly available data collected from the German Wikipedia to assess whether offline meeting participation affects editors' behaviour in three different domains: 1) productivity and collaboration, 2) norm-relevant behaviour, and 3) election participation. Data was collected on over 4000 meetings covering the period between the creation of the German Wikipedia in 2001 to March 2020. In the first substantive chapter of this thesis, matching meetup attendees with a comparable control group and employing a difference-in-differences design, I find positive and significant effects of meetup attendance on productivity on Wikipedia, measured as the number of edits. In the second substantive chapter, I build upon the theoretical arguments put forward by Coleman (1990) and test whether offline network density influences norm-relevant behaviour. I find only limited importance of the offline network: those attending meetups tend to both experience and conduct fewer norm violations, and they give and receive generally more rewards. However, the density of the offline network does not play a noteworthy role in explaining online norm violation and norm enforcement, except that those in high-density off- line networks generally give fewer rewards. Lastly, for the third substantive chapter, I collected data on all elections for administrators on the German Wikipedia. Using hybrid multilevel random effects models, I find that offline participation measures influence whether one is successful as a candidate, and whether and how one votes. This highlights important processes in situations of public elections. This study is one of the first to bridge the gap between online and offline behaviour, using digital trace data and offline meeting data on a large scale. The findings emphasise how offline interactions in online communities can affect the community and the important role of social capital. They have implications for online communities and Wikimedia in regard to understanding the importance of meetups and (inequality in) access to meetings
