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
Management consulting : structure and growth of a knowledge intensive business service market in Europe
No full textThe globalisation of contemporary capitalism is bringing about at least two important implications for the emergence and significance of business services. First, the social division of labour steadily increases (ILLERIS 1996). Within the complex organisation of production and trade new intermediate actors emerge either from the externalisation of existing functions in the course of corporate restructuring policies or from the fragmentation of the production chain into newly defined functions. Second, competitive advantages of firms increasingly rest on their ability to innovate and learn. As global communication erodes knowledge advantages more quickly, product life cycles shorten and permanent organisational learning results to be crucial for the creation and maintenance of competitiveness. Intra- and interorganisational relations of firms now are the key assets for learning and reflexivity (STORPER 1997). These two aspects of globalisation help understand why management consulting - as only one among other knowledge intensive business services (KIBS) - has been experiencing such a boost throughout the last two decades. Throughout the last ten years, the business has grown annually by 10% on average in Europe. Management consulting can be seen first, as a new organisational intermediate and second, as an agent of change and reflexivity to business organisations. Although the KIBS industry may not take a great share of the national GDP its impact on national economies should not be underestimated. Estimations show that today up to 80% of the value added to industrial products stem from business services (ILLERIS 1996). Economic geographers have been paying more attention to KIBS since the late 1970s and focus on the transformation of the spatial economy through the emerging business services. This market survey is conceived as a first step of a research programme on the internationalisation of management consulting and as a contribution to the lively debate in economic geography. The management consulting industry is unlimited in many ways: There are only scarce institutional boundaries, low barriers to entry, a very heterogeneous supply structure and multiple forms of transaction. Official statistics have not yet provided devices of grasping this market and it may be therefore, that research and literature on this business are rather poor. The following survey is an attempt to selectively compile existing material, empirical studies and statistics in order to draw a sketchy picture of the European market, its institutional constraints, agents and dynamics. German examples will be employed to pursue arguments in more depth
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
