Abstract: This article highlights one of the major benefits of qualitative comparative methodology as applied within a “small-N” research design, namely its potential use for specifying the scope conditions of
(theoretically competing) causal mechanisms. It is argued that the identification of set-theoretic relationships, multiple paths, and analytic efforts in typological mapping can make valuable contributions to the elaboration and further development of middle-range theory.

Abstract: The researcher as bricoleur will gather whatever data is at hand, experimenting and exploring to find answers to the questions he or she has set. With computer in hand and new tools
available, the researcher can readily combine data types, moving beyond complementarity and simple triangulation. Data may be transferred in either or both directions between
NUD•IST (a program to assist the analysis of qualitative data) and a spreadsheet or statistical package. Thus, analysis and interpretation are enriched, and new ways of thinking about
data are laid open. Such techniques inevitably challenge traditional assumptions about particular methods. But perhaps in the final analysis, all methods, other than those employed in
reductionist, hypothesis testing experiments, are essentially interpretive.

Abstract: The central goal of the seminar is to enable students to create and critique methodologically sophisticated case study research designs in the social sciences. To do so, the seminar will explore the techniques, uses, strengths, and limitations of case study methods, while emphasizing the relationships among these methods, alternative methods, and contemporary debates in the philosophy of science. The research examples used to illustrate methodological issues will be drawn from international relations, comparative politics, and American politics. However, the methodological content of the course is also applicable to the study of history, sociology, and economics.

Abstract: There are some new attempts to bridge the divide between quantitative and qualitative methods in the social sciences. My paper explicitely illustrates and tests some of these methods like regression, cluster, or discriminant analysis, on the one hand, and more recent case- and diversity-oriented methods like QCA, Fuzzy Sets and similar ones, on the other. This is done by using examples and data for different empirical theories of democracy such as those by Lipset, Vanhanen, or Moore/Stephens. In this way, the specific strengths and weakenesses of the respective methods and theories are demonstrated.

Abstract: Recent writings concerning measurement of political democracy offer sophisticated discussions of problems of conceptualization, operationalization, and aggregation. Yet they have less to say about the error that derives from the use of inaccurate, partial, or misleading data sources. Drawing on evidence from five Central American countries, the authors show this data-induced measurement error compromises the validity of the principal, long-term cross-national scales of democracy. They call for an approach to index construction that relies on case expertise and use of a wide range of data sources, and they employ this approach in developing an index of political democracy for the Central American countries during the 20th century. The authors’index draws on a comprehensive set of secondary and primary sources as it rigorously pursues standards of conceptualization, operationalization, and aggregation. The index’s value is illustrated by showing how it suggests new lines of research in the field of Central American politics.

Abstract: To what extent is globalization given an institutionally elaborated definition in studies on its welfare, welfare state and/or
social policy impacts published since 1995? And, is it seen to inhibit or stimulate welfare (state) development? These questions are addressed
through a study sample (N = 161) from the International Bibliography of the Social Sciences, subjected to combinatory analysis similar to
qualitative comparative analysis (QCA) using a pre-typological classification of definition components. Disaggregated definitions
oriented to relations and actors (most often trade and/or competition as well as international organizations) coincide with polarized welfare
(state) impacts, envisioned or real, of globalization. Positive overall globalization impacts are rare in this literature. Mixed or zero impacts
claims are more common in studies including an arena-related component (often global market integration) in defining globalization,
possibly indicating less determinism in views thereof, but also conventionalism in perspectives on markets. Future research needs
more methodological rigour and scepticism of overgeneralized assertions on globalization’s impacts.

Abstract: = L'analyse comparative des attitudes et comportements politiques a connu au cours des trois dernières décennies d'importants développements. Un certain nombre de programmes internationaux ou européens de collectes d'enquetes par sondages ont vu au cours de cette période (les enquetes sur les Valeurs des européens, l'Intenational Social Survey Programme). L'un des objectifs importants de cette contribution sera de porter un regard, parfois critique, sur les apports et les limites de ces enquetes à l'analyse politique comparative. Il serait notamment intéressant de procéder à une évaluation de ces programmes d'enquetes et des résultats des travaux qui en sont issus à l'aune des bilans que les auteurs des années 60 et 70 tiraient eux-memes.
Par bien des aspects en effet, il semble qu'il faille, malgré les importants progrès réalisés dans l'organisation internationale de la recherche et l'apparition de dispositifs opérationnels de collecte de données, revenir sur un certain nombre de vieux problèmes parfois en voie de résolution, parfois non...
L'objectif de cette communication est de proposer un balisage de ces vieux problèmes et des solutions offertes par l'analyse des données elles-memes.

Abstract: QCA is increasingly receiving attention by social science researchers, but as the number of publications using the method rises, the main limitations of QCA, the necessity to use dichotomized variables and the deterministic algorithms of the QCA software, are being exposed. In my paper I want to present an extension of QCA with Multi-Value sets, allowing the researcher to use more finely graded scales with QCA instead of only using dichotomous sets.
An introduction to MVQCA (Multi-Value QCA) is given, mainly the origin of MVQCA and the difference to QCA will be explained. The method will be demonstrated by comparing strictly dichotomous data set calculations with a multi value data set minimization. Then the range of data sets which are possible to deal with in QCA, MVQCA and FS/QCA will be discussed, including the possibility to abandon the deterministic nature of Boolean minimization by giving special attention to configurations almost only representing cases with identical outcomes, which could extend the use of (MV)QCA to more-than-small size Ns. Also some of the shortages of the Fuzzy Set approach will be mentioned (problematic probabilistic calculations, mixing fuzzy and non fuzzy variables).

69. DE GRAAF, Theo K. "From Hermeneutics to Empiricism: Extracting Testable Research Hypotheses From the Study of Individual Cases.", 2001.
Abstract: There is increasing awareness of the lack of both comprehensiveness and specificity of current psychiatric classification systems. Apparently, the old Kraepelinian ideal of nosological entities characterised by the same cause and the same optimal treatment, does not hold. Co-morbidity constitutes a major obstacle for research as well as for evidence-based treatment programs. The author proposes a “bottom-up” approach with the help of multiple N=1 studies of individual cases sharing the same behavioural, cognitive, and/or affective symptoms, in the vein of Ragin’s method of qualitative comparison. In this way, possible psychodynamic, psychotoxic, and genetic influences leading to psychopathology can be mapped and built into hypotheses for subsequent quantitative research. With the help of in-depth observations on a limited number of juvenile delinquents, it can be shown that such a heuristic procedure may result in the establishment of a causal-developmental profile. In comparison with conventional diagnosis, such a causal-developmental profile matches more closely the life experiences and inner world of the patient and will therefore lead to more adequate treatment strategies.

70. DE GRAAF, Theo K. "From Hermeneutics to Empiricism: Transformation of Psychodynamic Reasoning and Concepts into Testable Research Hypothesis.". Universiteit van Tilburg (KUB), 2002.
Abstract: The starting point for this methodological study is the assumption that one and the same psychiatric or psychosomatic (in brief: 'psychobiological') disease, such as e.g. a depressive illness, may be brought about by more than one 'causal chain' operating as a sufficient condition. In some of these 'causal chains' psychotraumatic experiences - including transgenerationally induced psychotoxic influences in the family of origin - may play the role of a necessary condition, in addition to other necessary conditions such as e.g. hereditary factors or physical birth trauma. Emotions which ultimately give rise to psychobiological disorder may stem from undigested traumatic experiences and conflicts in the individual's past, including early childhood. The latter sensitize the individual to events in adu lt life which in that person's perception exhibit a certain resemblance or congruity with the original traumatic experience. Accordingly, the intrapsychic representation of this early, undigested traumatic experience is called Personal Sensitization Factor (PSF), and the precipitating, or 'trigger', event is called the Congruent Life Event (CLE).
After having elaborated on the methodological problems connected with the operationalization of these psychodynamic concepts and constructs, and with qualitative multivariate research on anecdotal material in the form of 'plural N=1 observations' for that matter, the author dwells upon the principles of causality in individual biological systems. This leads to a discussion of the concept of 'causal chain', and of the difference between the principles of 'multiconditionality' and 'multicausality' in pathogenesis.
With the help of a clinical example of a multivariate study of ten (hypothetical) tuberculosis patients, the reader is then introduced to Ragin's method of 'qualitative comparison' and to the methodology of 'multiple N=1 studies'. The ensuing 'truth-tables', entirely basd upon binary data, can be analyzed with the help of Boolean logic. This analysis yields clusters of causative factors which, in turn, can be used as starting points for setting up hypotheses and designs for multivariate case-control, or even epidemiological studies. What is proposed here is, in fact, a qualitative paper-and-pencil cluster analysis for small samples and for data which are entirely binary.
The foregoing both statistical and psychodynamic principles are applied to an (imaginary) sample of sixteen bus drivers, some of whom had developed an incapacitating depressive illness following an accident in which at least one person had been killed. The PSF, figuring as a so-called 'latent variable', was operationalized - at least partly - with the help of two measurable 'indicator' variables, namely 'early loss of a parent or of a close friend' and 'parent lost a child'. In 13 of the 16 cases (= 81.25%) either presence or absence of depressive illness could be entirely accounted for by respectively presence or absence of the aforementioned two indicator variables.


71. DE GRAAF, Theo K. "Trauma and Psychiatry. The Role of Individual and Transgenerational Traumatisation in the Causation of Psychobiological Illness.". Universiteit van Tilburg (KUB), 1998.
Abstract: (...) Theo de Graaf tries to formulate a provisional answer to this question by referring to the experience gained by himself and others from the treatment of severely traumatised individuals. These may be people who themselves have endured severe traumatic experiences, such as internment in a concentration camp and/or the loss of close relatives; bombardments, at the front, or as a civilian; the death of friends during combat; incest or severe neglect as a child; &c.. A second group consists of persons who have been secondarily traumatised and psychically damaged, having been born to parents who themselves suffered some of the aforementioned tragedies, and as a consequence were not able to bring up their children in a healthy and loving manner. In this dissertation the family dynamics and projective mechanisms underlying this so-called 'transgenerational' traumatisation are extensively dealt with. With the help of clinical examples and small studies of juvenile delinquents and patients suffering from depressive and psychotic illness, as well as from auto-immune disease (multiple sclerosis), the author presents a psychobiological causality model which could explain the different ways in which psychotraumatic and 'psychotoxic' experiences could eventually lead to a number of forms of psychobiological illness. A separate chapter [Chapter IV] is dedicated to the principles of multicausal and multiconditional causation in individual biological systems, and to the methodological and statistical consequences thereof for clinical research.

Abstract: The goal of the course is to help students develop proficiency in the use of qualitative methods in two respects. The first is to understand and be able to articulate the assumptions about the political world and arguments about scientific knowledge on which qualitative approaches in
political science are grounded. We will devote particular attention to the question of how research designs involving relatively small numbers of intensive observations can be used to develop and test theory in political science. The second type of proficiency the course will help students develop involves basic knowledge of the principal techniques used by political scientists who do qualitative research. Our objective is to help students develop the methodological tools needed to pursue rigorous qualitative research for the dissertation, either as a supplement to quantitative analyses or as the principal research strategy.

Abstract: Understanding the linkages in an input-output system has been addressed by various methods, but many focused on the identification of key sectors in the economy. Sonis et al. (1996) offered as a field of influence theory an alternative approach focusing on analytical importance of elements and combinations of elements. The first objective of this paper is to offer a complementary approach to the field of influence and the so-called 'Matrioshka principal' (Sonis and Hewings, 1990); the adopted approach seeks hierarchial associations (i.e. statistical dependence) between supply and demand in input-output system. The second objective of this paper is to examine the cluster structure sales and purchases profiles when the principle of 'excluded middle' is violated by the use of fuzzy sets. Both approaches are based on the data analysis technique known as dual scaling (Nishisato, 1980, 1994). Results of this approach will be applied to input-output tables of the US and Canada.

Abstract: Any minimization problem involves a computer algorithm. Many such algorithms
have been developed for the boolean minimizations, in diverse areas from
computer science to social sciences (with the famous QCA algorithm).
For a small number of entries (conditions in the QCA) any such algorithm will
find a minimal solution, especially with the aid of the modern computers. However,
for a large number of conditions a quick and complete solution is not easy to find
using an algorithmic approach, due to the extremely large space of possible
combinations to search in. In this article I will demostrate a simple alternative solution, a mathematical
method to obtain all possible minimized prime implicants.
This method is not only easier to understand than other complex algorithms, but
it could prove to be a faster method to obtain an exact and complete boolean
solution.

"How the Cases You Choose Limit the Questions You Ask: Selection Problems in Comparative Research Designs." 2nd ECPR General Conference, Section "Methodological Advances in Comparative Research : Concepts, Techniques, Applications", Panel "Systematic Qualitative Comparisons in Comparative Research": 2003.
Abstract: The paper discusses the problems of case selection in comparative cross-national research, that is, how the cases you choose limit the questions you ask. It discusses the pitfalls of quantitative cross-national research, arguing that selection bias is not unique to small-N studies but inherent to the study of real world social systems. All comparative research of social entities, whether quantitative or qualitative, face the problem of limited diversity, the fact that the potential pool of cases has been selected by historical social processes. In small-N studies, the purpose of comparison and the subsequent research design assumes a particularly important role as cases do not represent observations for extensive variable analysis but determine the contexts for intensive within case analyses, the results of which are then compared. For what purpose are cases chosen? Are they selected to elicit unique cases departing from general patterns, to find common causes among cases with similar outcome, to control for similar context conditions, to test predictions by universal hypotheses, to understand the impact of context conditions on causal mechanisms? The paper discusses the consequences of the interaction between research question and research design with examples from cross-national studies of modern welfare states.

Abstract: Les politologues ont pour tradition de célébrer la comparaison pour son oeuvre de fondation de leur discipline. Un survol de publications récentes montre cependant à quel point, la science politique est aujourd'hui critique vis-à-vis de sa méthode fétiche. Les politologues critiquent inlassablement et parfois amèrement mise en application et résultats du comparatisme (Apter, 1996; Frognier, 1994; Hassenteufel, 2000; Smith, 2000), proclament cent fois la nécessité d'innover radicalement (Levi, 2000; Ragin, 1996), ou au contraire, de retrouver la sagesse et la force de mettre en oeuvre les règles et les méthodes traditionnelles et fondatrices de la discipline (Sartori, 1994).

Science." Studies in Comparative International Development 41.2 (2006): 88-109.
Abstract: Political scientists of all stripes have proposed numerous necessary or sufficient
condition hypotheses. For methodologists a question is how can we assess tlie importance
of these necessary cotiditions. This article addresses three central questions
about the importance of necessary or sufficient conditions. The first concerns
the "triviainess" of necessary or sufficient conditions. The second is how much a
necessary or sufficient condition is "relevant?" The third important question deals
with Ihe relative importance of necessary or sufficient conditions: for example, if A",
and A', are necessary or sufTicient conditions., is one more important than the other?
The article develops measures to assess the importance of necessary or sufficient
conditions in three related contexts: (!) Venn diagrams, (2) 2 x 2 tables, and (3)
fuzzy sets. Two empirical examples are discussed at length: (1) Skocpol's States and
Social Revolutions: A Comparative Analysis of France. Russia, and China atid (2)
Ragin's (2000) analysis of the causes of IMF riots.

Abstract: Assessing the importance of necessary or sufficient conditions in fuzzy-set social science
Political scientists of all stripes have proposed numerous necessary or sufficient condition hypotheses. For methodologists a question is then how can we assess the ``importance'' of these necessary conditions. This paper addresses two central questions about the importance of necessary or sufficient conditions. The first regards their ``absolute'' importance which is addressed via the concept of the trivialness of necessary or sufficient conditions. The second importance question deals with the relative importance of necessary or sufficient conditions: for example, if X_1 and X_2 are necessary or sufficient conditions, is one more important than the other? The paper develops measures to assess the importance of necessary or sufficient conditions in three related contexts: (1) Venn diagrams, (2) 2x2 tables, and (3) fuzzy logic, with an emphasis on fuzzy logic methods. The empirical analysis uses the measures of absolute and relative importance to extend Ragin's (2000) discussion of the causes of IMF riots.

Abstract: Two-level theories explain outcomes with causal variables at two levels of analysis that are systematically related to one another. Although many prominent scholars in the field of comparative analysis have developed two-level theories, the empirical and methodological issues that these theories raise have yet to be investigated. In this article, we explore different structures of two-level theories and consider the issues involved in testing these theories with fuzzy-set methods. We show that grasping the overall structure of two-level theories requires both specifying the particular type of relationship (i.e., causal, ontological, or substitutable) that exists between and within levels of analysis and specifying the logical linkages between levels in terms of necessary and sufficient conditions. We argue that for the purposes of testing these theories fuzzy-set analysis provides a powerful set of tools. We illustrate this by doing an empirical, fuzzy-set of Skocpol's States and Social Revolutions. However, as the Skocpol example shows, fuzzy-set methods are not effective if the investigator fails to be clear about the two-level structure of these theories from the onset.

Abstract: Linguists searching about laws of phonetic changes make use of the entire corpus at their disposal. By so doing, they find laws that correctly describe observed changes, especially " splits ", but can't be checked. Such a law may always be found if using enough parameters, but doesn't guarantee a fair description. In a Popperian perspective, we'd like to suggest working on a partial corpus, trying to establish laws that correctly account for all matching multiplets considered, then applying these assumed laws to the rest of the corpus ; if no counterexample is found, the set of laws gains in credibility.
In this approach, QCA may be very useful, because it allows us to : 1) consider all possible influences (position in the word, preceding and following phoneme, umlaut/ablaut, position relative to stress, …) as conditions ; 2) use contradictions as guides to the detection of influences we forgot to use ; 3) modify the corpus and set of conditions at will ; 4) produce several laws, among which we may choose the most plausible ; 5) find implications that aren't seen at first glance.

Abstract: Multiple case studies are frequently used to test causal claims. Because of the small number of cases involved, however, causal inference from these studies is problematic. In this article, these problems are discussed in the context of studies of the determinants of environmental policy. Starting from six crucial assumptions underlying causal inference from small-N studies, it is shown that some of these assumptions can be weakened by the systematic use of theory in the selection of cases and by process tracing. Also, Charles Ragin's method of Qualitative Comparative Analysis is examined to see to what extent it escapes the limitations of traditional small-N studies. Although a number of limitations can be overcome by (a combination of) these methods, causal inference from small-N studies remains especially vulnerable to the quality of the theory that is used and the way the variables are measured.

Abstract: The literature on the methodology of comparative research is extensive. Major perspectives are focussed on 1. Definitions: which research should be called comparative? 2. Typologies: what comparative research strategies can be identified? 3. Techniques: what are the conditions for the proper use of a particular strategy? This article does not try to summarize, let alone synthesize this body of literature but opts for a different approach. It is argued that a simple cross table of the unit of analysis, the properties of that unit and the research question at hand can be used as a frame for analyzing (comparative) methods of analysis. The author is tributary to Charles Ragin and Howard Becker for the ideas presented.

Abstract: This paper aims at illustrating under which circumstances QCA and its ramifications, fs/QCA and MVQCA, become particularly useful tools of analysis. To this end, we discuss the
most pertinent problem which researchers encounter when using QCA, namely the problem of contradicting observations. In QCA analysis, contradictions arise from the sheer number of cases,
as well as the problem of dichotomisation. Therefore, we argue that – in order to handle contradictions – the method for analysing middle-sized-N situations should be chosen according
to two parameters: The size of a dataset on the one hand, and the need to preserve raw data information on the other. While QCA is a particularly adequate tool for analysing comparatively
small middle-size datasets with a reduced necessity to preserve cluster information, the opposite holds true for fs/QCA. MVQCA, in turn, strikes a balance between these two methods as it is
most suitable for analysing genuinely middle-size case-sets for which some cluster information needs to be preserved.

Abstract: In this paper, it is argued that the fuzzy set approach can engage in a fruitful liaison with constructivist research. There are several
important properties of fuzzy set analysis that overlap with constructivist theorizing and research practice. To demonstrate
the usefulness of the approach, Niemann’s study on the conditions for communicative action is replicated and re-interpreted using
fuzzy sets. The result is an improvement of the informational content, the precision and the validity of conclusions drawn from
the empirical analysis. Furthermore, the re-interpretation points to theoretical and conceptual issues that need more consideration in
future research.

Abstract: This paper attempts to further Rueschemeyer, Stephens, and Stephens's (1992) comparative historical analysis of democratization and theory building for their Latin American cases by using Qualitative Comparative Analysis (QCA) as a technique for the implementation of analytical induction (Hicks 1994). For early waves of democratization two paths are identified. One is defined by (moderate) non-mining export sectors aided by clientelistic parties. The other is constituted by the same sectoral configuration aided by elite contestation. For latter waves, three alternative configurations are defined. For all these three configurations, given the presence of political parties during the second democratic period the combination of two of the following three factors allows for second wave stable democracies: 1) the absence of industrialization preceding democratization processes; 2) the presence of strong mechanisms of elite contestation (under the form of electoral contestation); and 3) the antecedent of previously stable democracies.

Abstract: This article introduces the qualitative comparative analysis (QCA) method, provides a detailed description of an early application in US public management research and draws lessons from the experience. In methodological terms, we show that QCA requires coding decisions that influence outcomes significantly and emphasize that this secondary data analysis technique be used in conjunction with primary methods in order to consider issues of process. The substantive findings from our application in a study of state-level barriers to policy diffusion indicate the potential of QCA as a systematic approach to the identification of linkages between causal factors that emerge as important to case study participants.

Abstract: The Osgood semantic differential approach is applied to assess the attitudes of groups of students towards economic life and the management of organizations. A questionnaire called CYRILE, for a study on "the Culture of Young people Regarding the Identity and Life of Enterprises" has been created, based upon the analysis of managerial work proposed by Henry Mintzberg.
Three dimensions of variability are inquired into, namely: (1)- the nationalities ; (2)- the 40 stimuli or elements of the economic life which are under comparisons; and (3)- the 30 constructs or "scales" on pair-wise opposite concepts;
Since the number N of individuals answering the Cyrile questionnaire is approximately 25 people per nationality, with each subject providing 1,200 points in a multidimensional space, the data analysis is not self-evident, when considering altogether the 4 sources of variability (= constructs * stimuli * nationalities * individuals).
Besides the question of semantic coherence between languages (French, Polish, English and Russian) , the Cyrile questionnaire raises the key point of the statistical value of inferences drawn from small-N samples of Law & Political Science students to economic cultures as a whole.
This communication suggests that at least a partial answer lies in the design of an inquiring system (West. C. Churchman's notion), - what could be called a "research information system" - , where the decomposition of the total data variability is insured through careful data exploration using not only statistical measures but also the systematic graphing of data sets.
This communication will present the difficulties encountered in comparing the individual and the averaged results, for each group of nationals.

Abstract: This paper advances a new method for studying ideal types, fuzzy-set theory, which is a framework that allows a precise operationalisation of theoretical concepts, the configuration of concepts into analytical constructs, and the categorisation of cases. In a Weberian sense ideal types are analytical constructs used as yardsticks to measure the similarity and difference between concrete phenomena. Ideal type analysis involves differentiation of categories and degrees of membership of such categories. In social science jargon, this means analysis involving the evaluation of qualitative and quantitative differences or, in brief, of diversity. Fuzzy set theory provides a calculus of compatibility. It can measure and compute theoretical concepts and analytical constructs in a manner that is true to their formulation and meaning. This paper sets out elements and principles of fuzzy set theory that are useful for ideal type analysis and presents two illustrative examples of how it can be used in comparative studies. The examples concern changing Nordic welfare policies in the 1990s, unemployment and child family policies, and relate to their conformity to predefined ideal typical models.

"The Tension Between Accuracy and Generalizability in Social Science Research Its Background and Dissolution." 2nd ECPR General Conference, Section "Methodological Advances in Comparative Research : Concepts, Techniques, Applications", Panel "Qualitative and Quantitative Methods in “Small N” Situations": 2003.
Abstract: In my paper I first claim that the the tension between accuracy and generalizability in social science research should be seen as a specific case of the general antagonism of ‘causality’ and ‘general laws’; the uniqueness being due to the fact that the relative autonomy of human agency, as opposed to mere behaviour of physical or biological 'actants', destroys the interchangeability of the actants’ behaviour (‘micro’) and the regularity this behaviour shows (‘macro’/’structure’). I than offer a solution based on Jean Piaget’s 'Genetic Epistemology' and its reconstruction of the four stages of 'cognitive ontogeny' as pre-mathematical systems of coordinated actions. ‘Pre-mathematical’ means that there is no perfect dialectics of 'element' and 'structure', the coordination of actions thus being only partial and, to the same extent, dependent on the contingency of the actors’ perspective. Thus, the ontogenetic ‘stages’ can be seen as formal models that could help to overcome the trade off between accuracy and generalizability. Indeed, the only thing that needs to do be done is to interprete them for the interindividual case, given that in ontogeny all the actions coordinated are the actions of only one single individual. Such an interindividual interpretation is completely unproblematic, on the other hand, because coordination is always the coordination of different perspectives and therefore the cause, not the result, of an integrated system such as a a ‘subject’.

187. LACEY, Rodney. "Creating Generalized Knowledge From Case Studies: a New Methodological Approach." The Strategic Management Society 21st Annual International Conference: 2001.
Abstract: Most strategic research is either specific case studies (N < 6), or generalizable quantitative studies (N > 100), because researchers lack methods for handling multiple case studies (N=10-50). This paper demonstrates a new methodology, based on boolean analysis, that can handle multiple case studies and simultaneously achieve tailored and generalizable models of strategic practice. Qualitative Comparative Analysis (QCA) (Ragin, 1987) allows for systematic, statistical analysis of causal relationships when the number of cases would be too small for standard statistical tests, but when the complexity of data is too great for traditional qualitative approaches. This paper illustrates the effectiveness and utility of the multiple case method and QCA by showing how independent variables affect organizational innovation in 30 hypothetical but representative case studies.

Abstract: The aims of this paper are to explore the role of variations and commonalities in Medium-N comparative analysis and to suggest a technique that could maximize their explanatory power in the context of medium-N comparative designs, especially those designs that combine two or more comparative approaches to the study of regulatory change. The paper identifies four popular comparative approaches to the study of politics and policy in general and regulation in particular. These four might best be titled the National Patterns Approach (NPA), the Policy Sector Approach (PSA), the International Regime Approach (IRA), and the Temporal Patterns Approach (TPA). While these approaches are not necessarily contradictory they represent different assumptions as to the determinant of political and regulatory change. Each of these approaches omits some important sources of variations and commonalties in the regulation of the economy and society. To overcome these omissions it is suggested that combinations of these approaches through complex research designs might prove a more sound and effective method for the study of regulation.

Abstract: This paper explores Duma elections in Russia (1993-1999) and Rada elections in the Ukraine (1994-2000). A methodological intrigue lies in the fact Ukrainian ruling elites began to exploit the strategy of party building later then in Russia, and in spite of the fact that at one point countries' institutional variables became 'similar', the political role of party principle remained 'different'. The paper points the question - what are the factors, accounted for such a puzzle, and what kind of expectations can be proposed about party system development in the countries.
To address this intriguing puzzle, this paper proposes a unique methodological solution to the problems described. In particular, the paper stresses the potential of comparative analysis for the investigation of new underdeveloped phenomena that often arise when dealing with transforming democracies.

Abstract: The arguments for the qualitative data analysis have been based on the standard critique of positivism. In this critique the difference between human and natural sciences is sometimes overemphasized.
There are, however, new trends in the philosophy of science and methodology that try to reconcile this issue. These are critical realism and closely connected to the former naturalism. In these methodologies the question of choosing a method in empirical research is seen only as a technical matter subordinated to the research issue. Thus these methodologies also emphasize intensive research and triangulation. They have made way to the variability of methods in empirical research.
Since the 1980’s mixing methods has further been facilitated by the development of computer programs planned to rationalize qualitative data analysis. These offer new technical opportunities for bridging the gap between the qualitative and quantitative analysis. The aim of this paper is to show how to cross the old border by using programs like QSR NVivo, MS Excel and SPSS. This will be illustrated by using two examples to show a) how the qualitative data can be analyzed quantitatively and b) how to categorize the open-ended answers of a survey for the further qualitative analysis.

Abstract: A central challenge in qualitative research involves selecting the “negative” cases (e.g., nonrevolutions, nonwars) to be included in analyses that seek to explain positive outcomes of interest (e.g., revolutions, wars). Although it is widely recognized that the selection of negative cases is consequential for theory testing, methodologists have yet to formulate specific rules to inform this selection process. In this paper, we propose a principle – the Possibility Principle – that provides explicit, rigorous, and theoretically-informed guidelines for choosing a set of negative cases. The Possibility Principle advises researchers to select only negative cases where the outcome of interest is possible. Our discussion elaborates this principle and its implications for current debates about case selection and strategies of theory testing. Major points are illustrated with substantive examples from studies of revolution, economic growth, welfare states, and war.

Abstract: One challenge for management research is to design research in such a way that it is relevant for and applicable to real world situations. The paper introduces a research strategy/design - systematic comparative case research - which can increase the direct relevance and applicability of research for management. The paper first of all discusses the limitations of two existing research strategies, namely single case-oriented qualitative research and variable-oriented quantitative research. In a next step systematic comparative case research is introduced, elaborated upon and discussed. The proposed research strategy aims to bridge the gap between qualitative and quantitative research from the perspective of qualitative research. In this sense the proposed research-strategy is fundamentally qualitative in nature. It interprets outcomes in the context of a case and aims to give an explanation for each outcome. This deterministic character of the approach allows for a more direct link between theory and action.

Abstract: QCA is normally used in political science and with nominal data. The aim of this paper is to present a way to combine QCA with quantitative data and methods. A number of European countries are compared according to their levels of fatal injuries and various structural factors. The method employed involves a combination of Qualitative Comparative Analysis (QCA) and Pearson correlation.
The QCA table presented shows a pattern where countries with a special combination of variable values have many traffic accidents and few suicides, whereas countries with the opposite pattern have few traffic accidents and many suicides. But it is hard to tell which variables impact on which. Correlation coefficients, however, reveal the importance of each specific variable in relation both to each other and to the outcome.
Combining QCA with Pearson correlations compensates for one of the disadvantages with QCA, namely the difficulty of ranking factors. Correlations, however, in one way functions similar to QCA in that it gives the same patterning of variables when not using partial correlations that control for other variables.

Abstract: Background : Multivariate analysis has mostly been performed using quantitative methods. In these, controlling for confounders and inter-correlated variables is treated as important. The aim of this paper is to discuss the role of confounders and inter-correlated variables when utilizing qualitative rather than quantitative techniques.
Material and methods: A number of European countries are compared according to their levels of fatal injuries and various structural factors. The method employed involves a combination of Qualitative Comparative Analysis (QCA) and Pearson correlation. QCA uses binary data, and has the advantage of being capable of presenting a pattern on the basis of a variety of variables. One disadvantage of OCA is that it is hard to rank factors in accordance with their importance. The advantage of Pearson correlation is that results can be presented in the form of a matrix displaying values on many variables.
Results: The QCA table presented shows a pattern where countries with a special combination of variable values - low GNP, high level of unemployment, high alcohol consumption and many Catholics - have many traffic accidents and few suicides, whereas countries with high GNP, a low unemployment rate, low alcohol consumption and few Catholics do not. But it is hard to tell which variables impact on which. Pearson correlation coefficients, however, reveal the importance of each specific variable. When the table provided by QCA is complemented with Pearson coefficients it is found that - although both unemployment rate and alcohol consumption contribute to the formation of the QCA pattern - their roles differ between rich, non-Catholic countries and less-developed, Catholic countries.
Discussion: Confounding variables, which in quantitative analysis are seen as problematic, can be regarded as an asset in qualitative analysis. The latter kind of analysis enables a patterning of cases that is not possible when relying solely on the former.

Abstract: This paper analyzes, based on Boolean approach by C.C.Ragin, how the subjective internal structures of social roles condition the possibility of role discrimination. I postulate, in an individualfs image, a role consists of some role elements, which construct an internal hierarchical structure (role image) depending on each elementfs contribution to the role discrimination as a whole. Then the role discrimination is formulated as a Boolean equation, taking the role elements as independent variables and the role discrimination itself as a dependent variable. Suppose a role X, and a performer who has image Xf and an observer who has image Xh communicate ea ch other. In general, between such two given actors, X can be discriminated by an observer under the condition that XfXh equals to Xh, or at least th at XfXh and Xh share one or more Boolean products; however, X is never di scriminated otherwise. At first, I take a simple case of two elements and examine the possibility of role discrimination for all possible combinations of images. After that, some general propositions as to the possibility of role discrimination, that hold regardless of the number of role elements, are derived.

." 4th Conference of the Asia Pacific Sociological Association: Asia Pacific Sociological Association, 2000.
Abstract: This paper analyzes, based on Boolean model of social role, how the subjective internal structures of roles condition the dyscommunication between actors. We postulate that a role consists of some role elements in an individual¹s image. Suppose a role X, and also suppose a performer who has image X¹ and an observer who has image X². In general, X can be discriminated by an observer under the condition that X¹X² equals to X², or at least that X¹X² and X² share one or more Boolean sum of products. The first order dyscommunication occurs when one or more role elements are not shared between subgroups of actors. Taking a simple model of two elements, we examine the cases in which this type of dyscommunication occurs. Even if each subgroup enrolls the different elements in the definition of role X respectively, actors might be confronted with the second order dyscommunication. Being a set of role elements commonly shared among actors does not mean everyone have same type of image; so that, the condition mentioned above may not be satisfied in some combinations between types. We examine such cases based on the extended three elements¹ model. An implied situation of this study is intercultural communication, as well as international marriage increasing in rural area of Japan.

Abstract: There is continuous debate whether theoretical models and research methods created in the Western world can be applied to the Eastern European cases. The usual practice is to use Western techniques without making any or making only some adjustments. This approach could be well illustrated with Manifesto Research Group (MRG) coding of Eastern European party programmes. However, the question whether this is a correct approach has never been thoroughly discussed. Since MRG project codes contents of the texts it is very important not to overlook what consequences for these contents have factors not directly related to them (for example, structure of the texts). This paper suggests that some in-depth qualitative analysis is needed in order to answer these questions.

Abstract: Process analysis constitutes a potential basis for casual explanations beyond mere correlation. This paper presents a methodology for processual strategy research that offers a systematic approach for casual explanation across complex sequences of events and enables consistent theorization about underlying casual mechanisms driving the processes. In addition, a comparative analysis of two organizational decline and turnaround processes is presented in order to illuminate the methodology and to construct a theory of casual mechanisms underlying the decline and turnaround process. The findings indicate that the turnaround is a matter of four necessary casual mechanisms that cumulatively and interdependently work against the mechanism of decline.

Abstract: What are the main variations in the constitutional control of the executive in 45 parliamentary democracies and how can these differences be accounted for? Four competing hypotheses, based on dichotomies, explain the degree of this control by means of contrasting institutional settings: consensus democracy versus majoritarian democracy, presidentialism versus parliamentarism, thick versus thin constitutionalism and established versus new democracies. These hypotheses are tested with the help of fuzzy-sets that allow for varying degrees of membership which go beyond the presence/absence suggested by these dichotomies. The necessary and sufficient conditions for constitutional control are specified with the help of this new methodology.
The fuzzy-set analysis shows that the degree of constitutional control can be explained solely by a specific combination of institutional conditions stemming from the four dichotomies and not by one single dimension. This constellation remains hidden for the traditional correlational techniques like regression. Hence, the fuzzy-set logic presents a promising new tool for comparativists that can be used to reveal causalities.
