Ticket-splitting and strategic voting under mixed electoral rules: Evidence from Germany
"There is more to strategic voting than simply avoiding wasting one’s vote if one is
liberated from the corset of studying voting behavior in plurality systems. Mixed electoral
systems provide different voters with diverse incentives to cast a strategic vote.They not only
determine the degree of strategic voting, but also the kind of strategies voters employ.
Strategic voters employ either a wasted-vote or a coalition insurance strategy, but do not
automatically cast their vote for large parties as the current literature suggest. This has
important implications for the consolidation of party systems. Moreover, even when facing
the same institutional incentives, voters vary in their proclivity to vote strategically." (author's abstract
The state of the art of teaching research methods in the social sciences: towards a pedagogical culture
No formal pedagogical culture for research methods in the social sciences seems to exist and, as part of the authors' endeavour to establish such a culture, this article reviews current literature about teaching research methods and identifies the gaps in the research. Articles in academic journals spanning a 10-year period were collected by searching academic catalogues and compiling a database of 195 articles published in 61 journals. These articles were reviewed and are discussed according to seven themes. Three specific gaps in research are identified that indicate some new agendas for research on teaching research methods in the social sciences. The implications for developing a pedagogical culture for research methods from the current literature reviewed are discussed
Technology diversification, coherence and performance of firms
Technological diversification at the firm level (i.e., the expansion of a firm's technology base into a wide range of technology fields) is found to be a prevailing phenomenon in all three major industrialized regions,—the United States, Europe, and Japan—prompting the term multitechnology corporation. Whereas previous studies have provided insights into the composition of technology portfolios of multitechnology firms, little is known about the relationship between technological diversification and firms' technological performance. Against a backdrop of the technology and innovation management literature, the present article investigates the relationship between technological diversification and technological performance, taking into account the moderating role of technological coherence in firms' technology portfolios. Hereby, technological coherence is defined as the degree to which technologies in a technology portfolio are technologically related. To measure the technological coherence of portfolios, a measure of technological relatedness of technology fields is constructed based on patent citation patterns found in 450,000 European Patent Office (EPO) patent grants. Two hypotheses are presented here: (1) Technological diversification has an inverted U-shaped relationship with technological performance; and (2) technological coherence moderates the relationship between technological diversification and technological performance positively. These hypotheses are tested empirically using a panel data set (1995–2003) on patent portfolios pertaining to 184 U.S., European, and Japanese firms. The firms selected are the largest research and development (R&D) actors in five industries: pharmaceuticals and biotechnology; chemicals; engineering and general machinery; information technology (IT) hardware (i.e., computers and communication equipment); and electronics and electrical machinery. Empirical results, obtained by fixed-effects negative binomial regressions, support both hypotheses in the present article. Technological diversification has an inverted U-shaped relationship with technological performance. Technological diversification offers opportunities for cross-fertilization and technology fusion, but high levels of diversification may yield few marginal benefits as firms risk lacking sufficient levels of scale to benefit from wide-ranging technological diversification, and firms may encounter high levels of coordination and integration costs. Further, the results show that the net benefits of technological diversification are higher in technologically coherent technology portfolios. If firms build up a technologically coherent diversified portfolio, the presence of sufficient levels of scale is ensured and coordination costs are limited. At the same time, technologically coherent diversification puts firms in a better position to benefit form cross-fertilization between technologies. The present article clearly identifies the important role of technological coherence in technology diversification strategies of firms
Reducing Complexity in Qualitative Comparative Analysis (QCA): Remote and Proximate Factors and the Consolidation of Democracy
Comparative methods based on set theoretic relationships such as 'fuzzy set Qualitative Comparative Analysis' (fs/QCA) represent a useful tool for dealing with complex causal hypotheses in terms of necessary and sufficient conditions under the constraint of a medium-sized number of cases. However, real-world research situations might make the application of fs/QCA difficult in two respects - namely, the complexity of the results and the phenomenon of limited diversity. We suggest a two-step approach as one possibility to mitigate these problems. After introducing the difference between remote and proximate factors, the application of a two-step fs/QCA approach is demonstrated analyzing the causes of the consolidation of democracy. We find that different paths lead to consolidation, but all are characterized by a fit of the institutional mix chosen to the societal context in terms of power dispersion. Hence, we demonstrate that the application of fs/QCA in a two-step manner helps to formulate and test equifinal and conjunctural hypotheses in medium-size N comparative analyses, and thus to contribute to an enhanced understanding of social phenomena
