No full textWereldwijd beperken infecties met gastro-intestinale nematoden het welzijn en de productiviteit van de veestapel. De meest voorkomende gastro-intestinale rondwormen bij rundvee in gematigde klimaatzones zijn Ostertagia ostertagi (in de lebmaag) en Cooperia oncophora (in de dunne darm). Controle van deze parasieten steunt voornamelijk op het gebruik van breedspectrum anthelminthica met een persisterende werking, met name de macrocyclische lactones (ML’s) zoals ivermectine, abamectine, doramectine, eprinomectine en moxidectine. Het intensieve en frequente gebruik van deze anthelminthica heeft echter geleid tot de selectie van ML-resistentie in deze economisch belangrijke maag-darm nematoden
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
