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 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.

Full Picture

An essential feature of the oral history project is the comparability of material once it has been collected. It should be made clear that for comparative analysis it is not essential (although it makes the work easier, if this has already been standardized) for all categories of data collection to be standardized in all countries studied; it is essential only that a full picture of all significant aspects of each movement will be covered--a task, as Professor Blanksten suggests, made easier by some forethought as to which categories should be covered in the interview. We assume that the categories not covered but very important in one or two countries will be recorded there if the interviewers perform their roles adequately. Certainly there are a number of extremely interesting problems that comparison would solve. What are the different speeds with which success or failure of these movements occurs? Why did some simply die out, others become dominant and successful, while still others become separatist tribal groups? If we use Professor Zolberg's categories plus others that turn up in the pilot study, and take account of Professor Cohen's strictures concerning quantification, then some answers may be forthcoming.

Depth Interviews

The use of audio recordings has become a taken-for-granted approach to generating transcripts of in-depth interviewing and group discussions. In this paper we begin by describing circumstances where the use of a recorder is not, or may not be, possible, before sharing our comparative analysis of audio-recorded transcriptions and interview scripts made from notes taken during the interview (by experienced, well-trained interviewers). Our comparison shows that the data quality between audio-recorded transcripts and interview scripts written directly after the interview were comparable in the detail captured. The structures of the transcript and script were usually different because in the interview scripts, topics and ideas were grouped, rather than being in the more scattered order of the conversation in the transcripts. We suggest that in some circumstances not recording is the best approach, not ‘second best’.
