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
Rubroboletus Kuan Zhao et Zhu L. Yang 2014, gen. nov.
No full textRubroboletus Kuan Zhao et Zhu L.Yang, gen. nov. Mycobank: MB 809235 Etymology: “ Rubro-” refers to the red color of the pileus, the surface of the hymenophore and the reticulum (or spots) on the stipe. Generic Type: Rubroboletus sinicus (W.F. Chiu) Kuan Zhao et Zhu L. Yang Basidioma stipitate-pileate with tubular hymenophore. Pileus hemispherical, convex or applanate, grayish, pinkish to red; context white, yellowish to lemon-yellow, bluing quickly when exposed. Hymenophore surface orange red to blood red, sometimes orange-yellow when mature, rapidly bluing when bruised; tubes yellow to olivaceous green, turning blue promptly when injured, then back to the original color slowly. Stipe central, covered with pinkish, red to brownish red reticula or spots. Pileipellis an interwoven trichoderm composed of more or less vertically arranged, sometimes gelatinized filamentous hyphae. Hymenophoral trama boletoid. Basidiospores smooth, subfusiform to ovoid-ellipsoid, slightly thick-walled. Pleuro - and cheilocystidia lageniform, thin-walled. Clamp connections absent. Amyloid reaction not observed.Published as part of Zhao, Kuan, Wu, Gang & Yang, Zhu L., 2014, A new genus, Rubroboletus, to accommodate Boletus sinicus and its allies, pp. 61-77 in Phytotaxa 188 (2) on pages 67-68, DOI: 10.11646/phytotaxa.188.2.1, http://zenodo.org/record/514715
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
