Constructing Social Research: The Unity and Diversity of Method (Sociology for a New Century Series)
The primary goal of Charles Ragin, social scientist and innovative methodologist, is to develop methods that help students and researchers unravel causal complexity in their research.  This has led to his developing and championing the use of set-theoretic methods in the social sciences, most notably, his Qualitative Comparative Analysis (QCA) and fuzzy set analysis.  In a recent review article in Contemporary Sociology entitled "The Ragin Revolution" (Vaisey review), sociologist Stephen Vaisey describes Ragin's work as a "principled alternative" to quantitative analysis (which assumes away casual complexity) and qualitative case-based methods (which lack tools for generalizing across cases.)  Many who have adopted Ragin's methods believe that these techniques combine the strength of both quantitative and qualitative methods, while transcending their limits.--This text refers to an alternatePaperbackedition.
