"The main aim of this paper is to demonstrate that the nature of the quantitative study of party competition related to the effects of electoral systems has been changing in the last few years. More differentiated, case oriented, approach has recently constituted what we call a second generation of the research techniques. We present some of them (notably party fragmentation indices and two graphical tools segmented Nagayama triangles and simplex representation) describing their underlying logic and delimiting their possible use. Furthermore, we try to explain the way of how this differentiation came into existence as an unintended effect of the Duvergerian debate, even of its otherwise incised meanders (the case of strategic voting and effects). As a case study, we provide the reader with the comparison of aligned and dealigned electoral competition in British elections (constituency level) of 1951 and 2005 respectively, being conducted using ElectMach under the regime of the differentiated approach."@en . .
