This year, the Nils Petter Gleditsch Article of the Year Award of the Journal of Peace Research was given to Corinne Bara for her article “Incentives and opportunities: A complexity-oriented explanation of violent ethnic conflict, Journal of Peace Research 51(6): 696-710″. In this study, QCA is used for examining the onset of ethnic conflicts between 1990 and 2009. We congratulate Corinne on this great achievement!
