In tenns of methodology, there has been a great deal of exchange over the past few years between sociology and political science, often resulting in joint sessions in international conferences and joint publications in which the Bulletin de Méthodologie Sociologique (BMS, or Bulletin of Sociological Methodology) has played a certain role (Marchand, 2005; Marchand, 2007a). Indeed, Marchand's work in political science recently resulted in the publication of a book that cites his contribution to sociological methodology and to the BMS, in particular (Marchand, 2007b).
