Thiratoscirtus oberleuthneri Seiter & Wesolowska, 2015, sp. nov.
No full textThiratoscirtus oberleuthneri sp. nov. urn:lsid:zoobank.org:act:69137100-27F6-42ED-8FD0-65BCAA296BA3 Figs 1–3 Differential diagnosis The male is distinctive in having a long anterior lobe of the bulb and in the presence of large terminal apophysis. An anterior lobe of the bulb is also present in T. perspicuus Wiśniewski & Wesołowska, 2013, but in the latter species it is clearly smaller and the embolus of that species is more delicate than in T. oberleuthneri sp. nov. The habitus of the newly described species is similar to that of T. torquatus Simon, 1903. Etymology The species name is a patronym dedicated to Anton Oberleuthner, who assisted during the field trip in Gabon. Type material Holotype GABON: ♂, close to Midzic, 0°49.781’ N, 11°29.395’ E, 329 m a.s.l., handcatch, 10–25 Feb. 2011, leg. M. Seiter (NHMW 21938). Description Dimensions Cephalothorax: length 3.3, width 2.6, height 1.8. Abdomen: length 3.4, width 1.8. Eye field: length 1.5, anterior width 2.3, posterior width 2.1. Male General appearance as in Fig. 1 A–B. Carapace oval, moderately high with gently sloping posterior part, fovea sulciform, clearly visible. Eye field occupies almost half of carapace’s length, distance between anterior lateral eyes slightly larger than between posterior laterals. Ocular area dark brown, almost black near eyes, thoracic part light brown anteriorly, darkening to black at margins, striae radiating from fovea. Carapace covered with fine light hairs, denser and longer on anterior part of eye field, a few long brown bristles near anterior row of eyes and laterally from eye field. Clypeus low, brown. Chelicerae large, with two teeth on promargin and single larger tooth on retromargin. Mouth parts brown. Sternum light brown, darker at edges. Abdomen slightly elongated, narrower than carapace, blackish with mosaic of small light dots, along dorsum wide serrated yellowish white band, tinged with brown anteriorly, sigilla visible. Venter dark grey, with four lines formed by light dots. Dorsum of abdomen covered with dense short brown hairs, with admixture of white in anterior part, a few brown bristles on anterior edge. Spinnerets black. Legs generally brown with yellowish transverse stripes: coxae and trochanters pale yellow, femora dark brown with two light rings, patellae light at base but dark distally, tibiae brown with median light ring, metatarsi as patellae, tarsi light. Hairs on legs brown. Spination of leg I: femur 0-1-1 dorsally, patella with one spine on pro- and retrolateral side, tibia 1-1 retrolaterally and 2-1-2 ventrally, metatarsus 1-1 pro- and retrolaterally and 2-2 ventrally. Pedipalp dark brown, clothed in dense long brown hairs, especially on prolateral side of tibia and prolaterally at tip of cymbium (Fig. 1 C). Bulb with very long anterior membranous protuberance curtaining embolus (Figs 1 C, 2 A), long terminal apophysis prolaterally from embolus (Fig. 2 A – B), tibial apophysis long (Fig. 2 B – D), cymbium narrow (Fig. 2 D). Female Unknown. Distribution This species is known only from the type locality in Gabon. Habitat The habitat is typical of a lowland rainforest in Gabon: sunlit, temperature around 33°C and high humidity. The specimen was found on the underside of a leaf in the vicinity of a small river (Fig. 3).Published as part of Michael Seiter & Wanda Wesolowska, 2015, Two new Thiratoscirtus species from Gabon (Araneae, Salticidae, Thiratoscirtinae), pp. 1-9 in European Journal of Taxonomy 123 on pages 2-5, DOI: 10.5852/ejt.2015.123, http://zenodo.org/record/88544
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
A revision of the ant-like salticid genera Enoplomischus Giltay, 1931, Kima Peckham & Peckham, 1902 and Leptorchestes Thorell, 1870 (Araneae: Salticidae)
No full textAbstractThree ant-like salticid genera, Enoplomischus Giltay, Kima Peckham & Peckham and Leptorchestes Thorell are revised. Kima is removed from the synonymy of Leptorchestes and revalidated. Three new species are described: Kima montana, Leptorchestes algerinus and L. separatus. Two specific names are synonymised: Enoplomischus chattoni Berland & Millot = E. ghesquieri Giltay and Leptorchestes halogena Metzner = L. mutilloides (Lucas). One new combination is proposed (K. reimoseri ex L. reimoseri). A lectotype for L. peresi is designated. L. semirufus Simon is regarded as nomen dubium. Identification keys are provided. A comparison of morphological features of the three genera indicates that Kima and Leptorchestes are more closely related to each other than either of them is to Enoplomischus. However, it seems still justified to place all three genera in the subfamily Leptorchestinae (sensu Simon 1901).
