Phanoperla wangi Wang, Li & Li 2022, sp. nov.
No full textPhanoperla wangi Wang, Li & Li, sp. nov. (Figs. 1–2) Male. Forewing length 10.2 mm. General body color light brown. Biocellate, ocelli brown, surrounded by black rings, ocelli nearly touching (Fig. 1a). Head pale, with a small brownish triangular marking forward of pale M-line; compound eyes large and black; antennae pale brown (Fig. 1a). Pronotum with well-delimited darker rugosities on pale disc, anterior and posterior margins dark brown, lateral margins pale with rounded corners (Fig. 1a); wing membrane pale, veins dark brown, Rs with two branches; femur pale brown, tibia brown. Abdominal segments generally pale brown. Terminalia. Sternum VI with weak setae and sternum VII with brushes of strong setae (Fig. 1c). Tergum IX with two large, separated patches of short setae beneath the tip of hemitergal processes, and several setae in medial shallow depression (Figs. 1b, d). Hemitergal processes of tergum X strongly sclerotized, its sharp tip curved outward, and stout basally (Fig. 1b). Aedeagal tube straight, boundary of dorsal sclerite unclear, covered by multiple rows of small spicules; ventral side of tube ending in a large subcordate protuberance covered with small distally spicules, apicolateral lobe curved dorsad and bald (Figs. 2a–b, d). Everted sac long and curved ventrad against protuberance covered with fine spicules, tubular apex of aedeagus with 5 irregular rows of ca. 30 strong hooks basally and fine small spicules distally (Figs. 2c–e). Female. Unknown. Type material. Holotype: male (CAUC), China: Yunnan Province, Dehong Dai and Jingpo Autonomous Prefecture, Yingjiang County, Tongbiguan Village, N24.6113°, E97.6569°, 1135m, 2017.V.29, Liang Wang leg., light trap. Etymology. The species is named after Dr. Liang Wang, collector of the holotype. Distribution. China (Yunnan). Diagnosis and remarks. The male of new species is characterized by the irregular hooks of tubular apex in aedeagal sac on the dorsal side. The new species is a typical member of Phanoperla maindroni group sensu Zwick (1982) by the enlarged ventrodistal protuberance on the apex of the aedeagal tube, which is against the recurved sac, and is closely related to P. maindroni Zwick, 1982 known from India by sharing nearly identical outline of aedeagus. However, their aedeagus are different dramatically. In P. wangi sp. nov., the apical protuberance of aedeagal tube bilobed but that in P. maindroni is entire; tubular apex of P. wangi has 5 irregular rows of strong hooks basally whereas the hooks of P. maindroni present before the tubular apex (Fig. 7b).Published as part of Wang, Yingying, Li, Wenliang & Li, Weihai, 2022, New species and records of Phanoperla (Plecoptera: Perlidae) from southwestern China, pp. 263-272 in Zootaxa 5120 (2) on pages 264-266, DOI: 10.11646/zootaxa.5120.2.6, http://zenodo.org/record/638929

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

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
