R.A. Wolinski. Type deposition. Holotype and paratype in UMMZ. Etymology. This species is dedicated to the late German acarologist, Dr. W. Fritsch author of an important early work on Harpirhynchidae. Hosts and distribution. Bombycilla cedrorum (Passeriformes: Bombycillidae) from USA (Michigan) (present paper). Differential diagnosis. Females of Crassacarus fritschi sp. nov. (males unknown) are close to those of C. sialia sp. nov. (see below) in having strongly elongated palps, four-segmented legs I and II, and two-segmented legs III. Females of these species differ from each other by the following features. In C. fritschi sp. nov., setae vF are smooth (vs. serrate in C. sialia sp. nov.), setae h 2 are 110 long (vs. 60–70), genua I and II bear one seta each (l’) (vs. without setae), leg III is with 4–6 setae (vs. 7 setae), and leg IV is with 5 setae (vs. 7 setae).Published as part of Bochkov, Andre V, Oconnor, Barry M. & Klompen, Hans, 2015, A review of the mite subfamily Harpirhynchinae (Acariformes: Harpirhynchidae) — parasites of New World birds (Aves: Neognathae), pp. 1-130 in Zootaxa 4023 (1) on pages 71-72, DOI: 10.11646/zootaxa.4023.1.1, http://zenodo.org/record/39983
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

Colouration [in ethanol]. Reddish brown with series of chevron like patterns on dorsal opisthosoma, legs banded (Figs 49c–d), ventral opisthosoma with V-shaped dark marking (Fig. 49d). Remarks. Koch (1873) described two females from the Mtuga Plateau, Morocco. He noted the general similarities in traits between this species and E. walckenaeri (sub Ocypete tersa). Simon (1880) listed this species as synonym of E. oraniensis but with a question mark (sub Sparassus oraniensis). Probably he did not see the syntypes, but referred to the colouration of the ventral opisthosoma for his judgment. The dark marking is a diagnostic character in all members of the dufouri group. In E. fritschi stat. rev. clear differences exist between the characters of the copulatory organs (especially the newly discovered male) compared to other species. Thus, species rank is re-established and the male is described here for the first time. Known geographical distribution and habitat. The Atlas Mountains in Morocco, river gravel under stones.Published as part of Moradmand, Majid, 2013, The stone huntsman spider genus Eusparassus (Araneae: Sparassidae): systematics and zoogeography with revision of the African and Arabian species, pp. 1-108 in Zootaxa 3675 (1) on pages 36-37, DOI: 10.11646/zootaxa.3675.1.1, http://zenodo.org/record/642259
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

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
