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

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

Holotype: male; type locality: Jinyunshan, Chongqing, China; location of type specimen: Zoologiacal Institute of Shaanxi Normal University. Redescription. Stridulatory file weakly curved, 1.9 mm long, with about 126 teeth. Male genitalia sclerotized, comparatively shorter, visible in dorsal view Discussion. The left tegmen together with its stridulatory file are very similar to the other species of the genus. Male genitalia sclerotized, shorter. Therefore, we transfer the species to the genus Acometura. The species differs from Acometura forcipata Liu, Zhou & Bi, 2008 in: body brown; subapical area of male cerci concave ventrad, broadened, apices with 1 small apical spine; female subgenital plate semicircular, basal margin slightly excavate, posterior margin obtusely rounded, median carina obviously raised.
