2-mode Conference

April 15, 2009
Conference and Workshop on 2-mode Social Network Analysis
VU University Amsterdam
30 September – 2 October 2009

The Department of Organization Science and the Department of Social Research Methodology at the VU University Amsterdam organize a conference and workshop which will be focusing exclusively on the analysis of 2-mode (affiliation) social network data (

I. CONFERENCE (October 1-2, 2009)

By bringing together researchers with a methodological and substantive background in social network analysis, this conference aims to provide a forum to share ideas and to further the development of substantive questions on those topics, which can be studied using two-mode (or more-mode) network data.

These include:

  •   interlocking directorates,
  •   voting-behavior and cosponsorship-behavior,
  •   membership of formal and informal groups,
  •   participation to specific events,
  •   contagion of diseases among cattle through the sharing of farms,
  •   the spread of diseases through sexual contact,
  •   collaborative work among scientists and shared projects,
  •   studies related to loyalty to institutions

The Keynote Speaker will be:   Steve Borgatti (University of Kentucky)


Innovative papers, on topics related to how and why network ties are formed in two-mode networks, the effects that such network structures have on the actors or events, as well as other research questions involving a two-mode network approach are welcome. In addition, papers on methodological problems related to two-mode network analysis are also encouraged.

Please note the following important deadlines:

  • Deadline for abstracts: April 29th, 2009
  • Notice of acceptance: May 25th, 2009
  • Deadline for papers: August 30th, 2009
II. WORKSHOP (September 30, 2009)

In recent years a number of specific methods and programs have been developed to analyse 2-mode network data.

Preceding the conference, three different workshops will be offered. Each workshop consists of one half-day hands-on tutorial on a specific method and program. Note that the ERGM and SIENA course are at the same time, and therefore cannot be combined.


  • Descriptive measures, techniques and visualization of two-mode data with UCINET (Steve Borgatti & Filip Agneessens)
  • Exponential random graph modelling (p*) for two-mode network data using BPNet (Peng Wang)
  • Longitudinal analysis of 2-mode network data using SIENA (Tom Snijders)

Please note that the number of places is limited and that the order will be based on date of payment received.

This year versus last year

January 13, 2009

This year’s course will be a little bit more practical and hands-on than last year. I’m adding more of a research design component to help people construct their own studies. Also, having a TA will allow us to insert some software tutorials to get people more comfortable with the software.
