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
Petersius Hilgendorf 1894
No full textPetersius Hilgendorf, 1894 TYPE SPECIES: Petersius conserialis Hilgendorf, 1894. Type by monotypy. DIAGNOSIS: Petersius is diagnosed by a unique cuspidation pattern of the inner row premaxillary dentition with the cusps of the cutting-edge oriented buccally (vs. lingually oriented in all other alestids), and the possession of a distinctively shaped margin of the supraoccipital with a steep anterodorsal convexity at the junction of the parietals followed by a dorsomedial concavity on the surface of the supraoccipital. DESCRIPTION. Corresponds to the description of the type species Petersius conserialis Hilgendorf, 1894. ETYMOLOGY. In naming Petersius Hilgendorf (1894) honored the naturalist and curator Wilhelm C.H. Peters of the Museum für Naturkunde, Berlin.Published as part of Melo, Bruno F. & Stiassny, Melanie L.
