No full textStenus mangdangshanus Liu, Tang & Luo, new species (Figs 1, 2, 11–14) Material examined. CHINA: Fujian Prov.: Holotype: ♂, glued on a card with labels as follows: “ China Fujian Prov., Nanping City, Mangdangshan Mt., mixed forest, leaf litter, sifted, alt. 300–1300 m, 8.XI.2015, Yan & Tang leg”. “ Holotype / Stenus mangdangshanus / Liu, Tang & Luo ” [red handwritten label] (SHNU). Paratypes: 1♂, same data as for the holotype. (SHNU); 1♂, same data as for the holotype, but alt. 400 m, 10.XI.2015. (SHNU). Description. Brachypterous; head blackish, pronotum and abdomen dark brown, elytra dark brown, each with an indistinct spot on median portion. Antennae, maxillary palpi and legs yellowish brown except antennal club infuscate. Labrum reddish brown. BL: 3.5–3.7 mm, FL: 1.6–1.7 mm. HW: 0.72–0.74 mm, PL: 0.54–0.57 mm, PW: 0.52–0.53 mm, EL: 0.58–0.59 mm, EW: 0.63–0.65 mm, SL: 0.43–0.47 mm. Head 1.13–1.18 times as wide as elytra; interocular area with two deep longitudinal furrows, median portion convex, slightly extending beyond the level of inner eye margins; punctures round, slightly larger and sparser on median portion than those near inner margins of eyes, diameter of large punctures about as wide as apical cross section of antennal segment II; interstices smooth, mostly narrower than half the diameter of punctures except those along the midline of the median portion, which may be wider than the diameter of punctures. Paraglossae oval. Pronotum 1.04–1.07 times as long as wide; disk relatively even, without distinct median longitudinal furrow; punctures round, slightly confluent, about the same size to large punctures of head; interstices smooth, much narrower than half the diameter of punctures. Elytra 0.91–0.92 times as long as wide; disk even; punctures round to elliptic, moderately confluent, slightly larger than those on pronotum; interstices smooth, distinctly smaller than half the diameter of punctures. Legs with tarsomeres IV strongly bilobed. Abdomen cylindrical; paratergites very narrow and almost impunctate, present only in segment III, tergites and sternites totally fused in segments IV–VI, posterior margin of tergite VII with indistinct apical membranous fringe; punctation of tergites III–VIII sparse and shallow, gradually becoming smaller posteriad; interstices smooth, mostly wider than diameter of punctures except those on basal impressions of tergites III–V, which may be distinctly narrower than half the diameter of punctures. Male. Sternite VII with inconspicuous emargination at middle of posterior margin; Sternite VIII (Fig. 11) with shallow emargination at middle of posterior margin; sternite IX (Fig. 12) with long apicolateral projections, posterior margin serrate. Aedeagus (Figs. 13–14) with apical sclerotized portion triangular; sclerotized expulsion clasps medium in size, median longitudinal bands with ventral bands each long, narrow, lateral longitudinal bands short; copulatory tube very long, rather slender, with main tube and basal chamber submembranous, the main tube gradually narrowing toward apex; parameres slightly longer than median lobe, swollen at apical parts, each with 11–13 setae on apico-internal margins. Female. Unknown. Distribution. China (Fujian). Remarks. The new species is similar to S. cooterianus Puthz, 2003 from Fujian, but can be easily distinguished from the latter species by the denser punctation of pronotum and elytra, the indistinct elytral spots and different sexual characters. Etymology. The specific name is derived from the type locality of this species.Published as part of Liu, Sheng-Nan, Tang, Liang & Luo, Yong-Ting, 2018, The Stenus cirrus group (Coleoptera, Staphylinidae) in Fujian, East China, pp. 105-115 in Zootaxa 4375 (1) on pages 106-107, DOI: 10.11646/zootaxa.4375.1.5, http://zenodo.org/record/115818

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
