Collective Action in Dutch Neighbourhoods


Henk Flap & Beate Völker – Utrecht University



We inquire into the importance of local neighbourhood communities as a source of collective action. We analyse the importance of meeting places, local networks, identification with the neighbourhood and the presence of a local community, as possible preconditions for collective action. Local collective action was quite frequent in the past (Tilly 1997). In this contribution, we inquire into the question to which degree collective action still can be found in Dutch neighbourhoods, and what conditions on the level of neighbourhoods as well as individuals explain differences in these actions.

Two normative conceptions of good civic community


Juno Blaauw – University of Amsterdam

Robert J. Mokken & Jean Tillie & Meindert Fennema – University of Amsterdam



This paper studies the conceptualization of  the idea of an ethnic good civic community within the context of Fennema and Tillie’s (1999; 2000) ethnic civic community perspective. This perspective enables us to formulate normative concepts fitting that idea. We introduce then two clearly operationalised concepts of good civic community — well-connectedness and an egalitarian degree distribution — which together define what makes a good civic community in terms of  the required network between organisations. A new evaluative network 

criterion is presented, followed with the result of an application in a study of the Turkish civic community in Amsterdam between 1994 and 2000.

Ethnic boundaries in students’ networks in Flanders and the Netherlands

Ethnic boundaries were tested in students’ networks in 34 Flamish and 19 Dutch high schools. Each network consisted of a school cohort in an intermediate level of education (track). While students from the native majority predominantly had friendships within their own ethnic category, minority students often had more inter-ethnic than intra-ethnic friendships. However, a multilevel p2 model for analyzing the networks showed that this was caused mainly by the quantitative dominance of native students in the networks. Native students were much less inclined to choose for inter-ethnic friendships than minority students. We found ethnic boundaries to be stronger in the Dutch networks than in the Belgian networks. Although this may be partly due to methodological reasons, it is still surprising that the boundaries in the Belgian networks were not stronger. The Dutch data stem from the pre-9/11 days when the Netherlands were still known for its tolerant climate; while the Belgian data stem from 2005 when one out of every five Flamish voted for an ethnocentric party.

From reconstructing social networks to an understanding of expert communities


Peter Groenewegen – Vrije Universiteit Amsterdam



The study of scientific communication has elucidated structural aspects of specialist communities.  Outside science studies, in knowledge management for example, the concept community has been used to delineate groups of actors that share views and action frames. Social network approaches have been used to analyze the interaction within communities. Research results from two PhD projects using social network analysis will be presented.

The first project studied open source software development and marketing.  Through snowballing and interviewing a list of central actors was drawn. The network of heterogeneous actors was derived from a network survey. This study suggests that collective action is important for legitimacy.

The second project was based on mining the web presence of semantic web researchers; in this project both cognitive and social network elements were used to derive networks. Social network analysis suggests lessons from both studies about the communication functions in communities. Bringing these approaches together it can be asked how social network analysis can be developed as a key aspect of to understand expert communities.
