Ischnocolus fasciculatus Strand 1906
No full textIschnocolus fasciculatus Strand, 1906 The type specimen, from Ethiopia, has been listed in Renner’s (1988) list of type species of the Stuttgart Museum, which was destroyed on 12 September 1944, during World War II. Therefore, this type specimen should be considered lost. The original description does not warrant recognition of the species and, therefore, the identity of I. fasciculatus cannot be confirmed. The species is here considered species inquirenda, pending the availability and careful examination of material from the type locality.Published as part of Guadanucci, José Paulo Leite & Wendt, Ingo, 2013, Revision of the spider genus Ischnocolus Ausserer, 1871 (Mygalomorphae: Theraphosidae: Ischnocolinae), pp. 387-402 in Journal of Natural History (J.

Ischnocolus tunetanus Pavesi 1880
No full textIschnocolus tunetanus Pavesi, 1880 Despite exhaustive research, the type-specimen, from Tunisia, was not located. It is possible that it is a junior synonym of I. valentinus, considering the overlapping of their geographical distributional range, and that I. valentinus is a wide spread species in northern Africa and Mediterranean region in Europe. The original description does not warrant recognition of the species and, therefore, the identity of I. tunetanus cannot be confirmed. The species is here considered species inquirenda, pending the finding of the type material or availability and careful examination of material from the type locality.Published as part of Guadanucci, José Paulo Leite & Wendt, Ingo, 2013, Revision of the spider genus Ischnocolus Ausserer, 1871 (Mygalomorphae: Theraphosidae: Ischnocolinae), pp. 387-402 in Journal of Natural History (J.

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
