Haematobosca aberrans Duvallet & Changbunjong 2020, sp. nov.
No full textHaematobosca aberrans sp. nov. (Figs 1–7) Diagnosis. Among the species with the palpus about as long as proboscis and grooved internally, the new species can be recognised by the absence of the anterior katepisternal seta together with arista plumose (not pectinate), and proepisternal depression, meron and prosternum bare. Etymology. The name indicates the aberrant feature of this species, namely the absence of the anterior katepisternal seta. Type Material Examined. Holotype ♂. THAILAND: Chiang Mai Province, Mae Wang district, N18°38’58.48’’ - E98°31’44.93’’, Nzi trap, 12.iii.2018, T. Changbunjong, in BMNH. Paratypes 2♂ 3♀. THAILAND: Data as for the holotype, in VSMU. Description. Male. Head (Figs 1–2). Ground-colour black. Eye bare; posterior eye-margin concave at middle. Frons narrow (Fig. 1), at narrowest point almost 3 times diameter of anterior ocellus. Fronto-orbital plate and parafacial silvery pruinose, gena and lower half of occiput whitish-grey pruinose. Fronto-orbital plates separated throughout by a distinct frontal vitta which at narrowest point is slightly narrower than diameter of anterior ocellus. Ocellar setae minute, fine, hardly distinct from adjacent setulae. 8–10 pairs of frontal setae, in a row from ocellar tubercle to lunule, all except the lowest pair proclinate. Antenna black; postpedicel barely twice as long as broad in lateral view. Arista with very long plumes dorsally and ventrally, bare on basal third ventrally. Gena linear, with short fine setae on margin. Palpus yellow, brownish near tip (Fig. 2). Proboscis dark brown, shining. Thorax (Figs 4–5). Ground-colour black. Scutum densely yellowish-grey dusted with a pair of broad black vittae running from neck to the middle of the scutum and laterally to postalar callus (Fig. 4), each vitta briefly divided with a narrow indistinct brown line; also with a median brownish line postsuturally that impinges on to base of the yellowish-grey dusted scutellum. Pleura yellowish-grey dusted. Spiracles brownish-yellow. Setae: acrostichals 0+1; dorsocentrals setulose, only 1 presutural and 2 prescutellar pairs detectable, only the last prescutellar pair well-developed; intra-alars 0+1; supra-alars 1+1; prealar absent; only 1 strong postpronotal; 2 postalars. Postalar wall and suprasquamal ridge bare. Notopleuron with 2 setae, each with several adjacent setulae. Prosternum bare. Proepisternal depression bare. Anepisternum with a fine seta in upper anterior corner. Anepimeron setulose on subalar sclerite and below. Katepisternal setae 0+1, the anterior one replaced by 1–2 tiny fine setulae (Fig. 5). Katepimeron and meron bare. Posterior spiracle without setae on posterior margin. Katatergite pilose. Anatergite bare. Scutellum with apical, lateral and subbasal lateral setae; disc sparsely setulose; lateral margin and ventral surface bare. Legs. Coxae and trochanters black. Femora black, yellow at tips. Tibiae black, yellow on basal third or more. Tarsi black. Fore tibia without submedian setae. Mid femur with only setulae on ventral surfaces; with a row of setae on basal half of anterior surface; 0 anterior and 1 posterior preapical seta, preceded by a series of short setae on apical half of femur. Mid tibia without submedian setae. Hind femur with 1 ventral seta near base and 1 anteroventral just before apex. Hind tibia without setae on the shaft, but the row of anterodorsal setulae well-developed; 1 dorsal but 0 anterodorsal preapical seta. Tarsi without setae or long hairs, but hind tarsomere 1 with a short anteroventral seta near base. Wing. Clear. Vein M bowed evenly towards vein R4+ 5 in apical half, and cell r4+5 at apex as broad as length of cross-vein r-m (Fig. 6). Veins bare, including base of R4+5. Calypters yellowish-white, the margins more smoky yellow. Haltere yellow. Abdomen. Ground-colour black. Tergites densely yellowish-grey dusted with black markings as follows (Fig. 7): syntergite 1+2 with a transverse crescent-shaped band; tergite 3 with a pair of large quadrate spots occupying the length of the tergite and with a broad black vitta on the dusted area separating them; tergite 4 with a pair of dark brown oval spots at middle of tergite and a black vitta on the dusted area separating them; tergite 5 unmarked. Sternite 1 setulose laterally. Terminalia not examined. M easurements. Wing-length, 3.5 mm. Body-length 4.0 mm. Female. Differs from the male as follows: Head.

Fronto-orbital plate at middle not much narrower than frontal vitta and with convex margins. Frontal triangle indistinct, narrow, grey, reaching lunule. Ocellar setae very short, setulose. 1 pair of frontal setae at lunule, and above this with 3 short frontal setae and 3 setulose exclinate orbital setae (Fig. 3). Frontal vitta without setae. Palpus brown in apical part. Thorax. The dark pattern reduced to absent before suture; after suture as in male but not so dark and therefore not so contrasting with the dusted areas. Legs. Hind femur with the posteroventral seta near base shorter and finer. Wing. Calypters and margins wholly creamy-white. Abdomen. Dark pattern reduced, with the dark spots smaller and the dark vitta on the dusted area separating them shorter and narrower. Terminalia not examined. Measurements. Wing-length, 3.0 mm. Body-length, 3.5 mm.Published as part of Pont, Adrian C, Duvallet, Gérard & Changbunjong, Tanasak, 2020, A new species of Haematobosca Bezzi (Diptera: Muscidae) from Thailand, pp. 538-544 in Zootaxa 4763 (4) on pages 539-542, DOI: 10.11646/zootaxa.4763.4.4, http://zenodo.org/record/376213

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
Variations on the Author
No full text“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
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
Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
The Thursday Murder Club: Launching a megabrand author - a publishing case study
No full textIn 2020, the Christmas book charts in the UK made headlines: Barack Obama’s eagerly awaited autobiography, The Promised Land, was beaten to the top spot by The Thursday Murder Club by Richard Osman, a debut cosy crime novel set in a retirement village. Not only did Osman’s book beat the former US president’s expected bestseller, it also broke records, becoming the fastest-selling debut crime novel of all time. Although Osman has a certain level of fame in the UK from his TV appearances on shows such as Pointless, his celebrity status does not entirely explain the novel’s huge sales. This article tracks the acquisition, publication, and promotion journey of The Thursday Murder Club in order to understand the industry and cultural context of its success and to interrogate the role of celebrity in the creation of author brands. The findings suggest that the unexpected scale of the success of the book owed to a number of factors, including in-depth editing by the novel’s agent, editor, and author to tighten up the plot, an extensive and strategic promotional campaign, the pandemic (which drove interest in the book’s genre and themes), and the quality of the writing. We find that the book’s success was accentuated by Osman’s celebrity status rather than being entirely reliant on it. This research adds to the growing scholarship on celebrity authorship by means of an in-depth case study and provides insight into the processes behind publishing a ‘celebrity’ book and launching a megabrand author
