Opadometa kuchingensis Dzulhelmi & Suriyanti & Zulqarnain & Norma 2015, sp. nov.
No full textOpadometa kuchingensis Dzulhelmi et Suriyanti, sp. nov. Etymology. The specific name is a noun, referring to the division in Sarawak where the holotype was collected. Diagnosis. The O. kuchingensis resembles O. fastigata and O. sarawakensis but can be differentiat- ed by the following: Epigyne: (1) The O. kuchingensis have shorter copulatory duct while O. sarawakensis copulatory ducts are more than half the spermathecae length Abdomen: (2) The O. kuchingensis has an oval abdomen that does not overhang the carapace while O. fastigata and O. sarawakensis has a pear-shaped abdomen and strongly overhangs the carapace. Legs: (3) The O. kuchingensis and O. sarawakensis have dense brush of hairs on tibia I and IV while O. fastigata has dense hairs on tibia IV only. Description. Female. Total length 7.05; Carapace: 3.33 long, 2.20 wide. Carapace light-brown in colour, carapace longer than wide (approximately 70%), cephalic area slightly narrower or nearly equal to thoracic area, sternum dark-brown in colour and slightly longer than wide in length, 1.27 long, 1.24 (Fig. 17). Eyes: diameters AME 0.18, ALE 0.10, PME 0.18, PLE 0.10; inter-distances AME–AME 0.14, AME–ALE 0.43, PME–PME 0.11, PME–PLE 0.36, PLE–PLE 0.10, AME–PME 0.21; clypeus 0.21 high. Lateral eyes loosely contiguous or almost so, eight eyes in slightly two recurved rows. PME slightly shorter than AME, distance between PME slightly shorter than between AME, PME size greater than distance between them, AME size about the same as distance between them, distance between PME and PLE are about two times the PME eye size (Fig. 16). Chelicerae: Promargin with series of 4 teeth, retromargin with series of 3 teeth (Figs 14, 15). Abdomen: abdomen 3.78 long, 2.44 width; Pear-shaped abdomen not overhanging the cephalothorax, light-orange abdomen colour with darker orange marking covering one third of the dorsal end of the abdomen, with black marking at the tip of the abdomen (Fig. 19). Spinnerets: Spinnerets at ventral tip of abdomen, tip of spinneret facing downward and does not exceed end of abdomen. Legs: Legs light-brown in colour with black annulations, Leg formula (I – II – IV – III), leg measurements (femur/ patella/ tibia/ metatarsus / tarsus/ total): leg I (4.78/1.11/4.01/5.44/ 1.56/16.90), leg II (4.01/1.02/3.22/3.89/1.22/13.36), leg III (2.44/0.68/ 1.56/2.02/0.89/7.59), and leg IV (4.44/0.89/ 3.00/3.78/ 1.11/13.22). Short spines on legs, Leg I: femur I with 3–5 spines, tibia I wit 3–4 spines, dense brush hairs covering more than one-third of the tibia, Leg II: femur II with 1–2 spines, tibia II with 3–4 spines, very few brush hairs covering more than one-third of the tibia, one row of short trichobothria covering half of retrolateral femur II, Leg III: femur III with 1–2 spines, tibia III with 3–4 spines, one row of short trichobothria covering more than two third of prolateral femur III; Leg IV: femur IV with 1–2 spines, tibia 4 with 3–4 spines, dense brush hairs covering more than one-third of the tibia, two rows of long trichobothria covering more than one third of the prolateral femur IV (Fig. 18). Epigyne: Epigyne simple and weakly sclerotized, spermathecae ovate and mushroom-like in shape, copulatory duct shorter than spermathecae in length (Figs 20, 21). Male. Unknown. Type material. Female holotype (BNP005) from Bako National Park, Sarawak, Malaysia (1°41’N, 110°26’E) was collected by hand-picking (Collector: Dzulhelmi Nasir) during the daytime at 11:30 hours on 27th April 2013. Distribution. It is only known from the type locality at the lowland dipterocarp forest in Sarawak. Natural history. Diurnal. The spiders were found resting at the center of its hub during the day light. The webs were constructed at 45° angle at an open space above 200 cm from ground which was covered with dense shrubs. Premature female of similar species were also found at close proximity to where this adult female was caught.Published as part of Dzulhelmi, Muhammad Nasir, Suriyanti, Su, Zulqarnain, Mohamed & Norma, Che Yusoff, 2015, Two new Opadometa species (Araneae: Tetragnathidae) from Sarawak, Malaysia, pp. 101-107 in Annales Zoologici 65 on pages 103-106, DOI: 10.3161/00034541anz2015.65.1.008, http://zenodo.org/record/118473
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
