Enhancing Sensitivity Diagnostics for Qualitative Comparative Anal- ysis: A Combinatorial Approach
نویسنده
چکیده
Sensitivity diagnostics has recently been put high on the agenda of methodological research into Qualitative Comparative Analysis (QCA). Existing studies in this area rely on the technique of exhaustive enumeration, and the vast majority of works examine the reactivity of QCA either only to alterations in discretionary parameter values or only to data quality. In this article, we introduce the technique of combinatorial computation for evaluating the interaction effects between two problems afflicting data quality and two discretionary parameters on the stability of QCA reference solutions. In this connection, we challenge a hitherto unstated assumption intrinsic to exhaustive enumeration, show that combinatorial computation permits the formulation of general laws of sensitivity in QCA, and demonstrate that our technique is most efficient.

The present research has aimed to present a model for and identify the dimensions and components of empowering developmental coaches and deputies in high schools. Taking a mixed, exploratory approach, the research used the strategy derived from grounded theory in the qualitative section, while a descriptive-survey method was used in the quantitative section. The statistical population for the f...

We present a general framework for proving combinatorial prophet inequalities and con-structing posted-price mechanisms. Our framework applies to stochastic welfare optimizationproblems, in which buyers arrive sequentially and make utility-maximizing purchases. Our anal-ysis takes the form of an extension theorem: we derive sufficient conditions for achieving welfarebounds i...
متن کاملThe Qualitative Descriptive Approach in International Comparative Studies: Using Online Qualitative Surveys
International comparative studies constitute a highly valuable contribution to public policy research. Analysing different policy designs offers not only a mean of knowing the phenomenon itself but also gives us insightful clues on how to improve existing practices. Although much of the work carried out in this realm relies on quantitative appraisal of the data contained in international databa...
