General information

Rense Nieuwenhuis is a PhD. candidate at the institute for Innovation and Governance Studies (IGS, University of Twente). In his thesis, he seeks to explain increased women’s employment rates in OECD countries, from 1970 onwards. The key innovation in his thesis is to combine demographic and institutional explanations of women’s employment. This will result in more accurate estimates of the effects of changing institutional contexts. More importantly, however, it will also contribute to a more detailed understanding on the degree to which women with different demographic backgrounds differ in the degree to which they benefit from these institutional developments.

His other main research interests include the detecting of influential data in multilevel models, and polarization of (abortion) attitudes. Regarding influential data, he released the ‘influence.ME’ software package for R, which provides tools for detecting influential data in mixed effects models. This software is used actively by several scholars, and publicly available from within the R-Project software.

Rense studied sociology at the Radboud University (BSc.), and graduated from the research master Social and Cultural Sciences in 2009 (MSc.). He graduated on a Master’s Thesis titled ‘North Americans’ Abortion Attitudes: A Multilevel Theory of Polarization in Public Opinion’. In this thesis, he developed an explanatory theoretical model on public opinion, and suggested a statistical approach for testing hypotheses derived from that model.


Rense Nieuwenhuis contributes to teaching several courses in both the Public Adinistration and Business Administration programs at the BSc. Level. He is involved in the courses:

  • Maatschappelijke Organisatie (Societal Organization)
  • Organisatie, Beleid en Regels (Organization, Policy, and Rules)
  • Service Management

In addition, he supervises a limited number of master and bachelor thesis, as well as trainees. He welcomes additional students to write their thesis on a subject related to women’s employment.
