Dolerus brevicornis ZADDACH 1859
No full textDolerus brevicornis ZADDACH, 1859 Baddoch, 1 ♀, 4.vi.2010, leg. Blank, Liston & Taeger. Dolerus brevicornis was only recently distinguished from D. asper Zaddach, 1859 (Heidemaa et al. 2004). Both species occur in the British Isles, but their distribution needs clarification. The above records are the first of D. brevicornis from Scotland.Published as part of Liston, A. D., Knight, G. T., Heibo, E., Bland, K. P., Barstad, Trond Elling, Blank, S.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
