Does Devolution make a difference? A comparison of party-group interaction in the Scottish Parliament and the Welsh Assembly.
No full textSignificant research has been dedicated to the question what roles members of parliament play within an assembly and how they shape them individually. (e.g. Searing 1994, Patzelt 1995, 1997, Müller et al 2001). Findings show that some differences in parliamentarians’ roles and behaviour are tied to the party’s status in parliament. However, most of the analyses in this field (exception: Müller et al 2001) do not consider how these characteristics are linked with the overall appearance of particular parliamentary party groups (PPGs) and their political strategies. Research conducted on the Bavarian Parliament (Steinack 2007 a, b) shows significant differences in PPGs’ strategies that relate to the MPs’ socio-demographic background and the party groups’ history and discussion culture. Based on preliminary results of an ongoing research project, the paper outlines how structural differences between parliamentary party groups in the devolved assemblies in Scotland and Wales shape strategies and political styles of their representatives. Interviews with members and clerks of the assemblies illustrate the findings

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
