This species is a relatively special one, with a unique shape of the procursus tip, and resembles P. qinghaiensis. It can be distinguished from the latter by the appendix with a longer branch proximally (Fig. 13F), by the shape of tip of the procursus (Figs. 13F–G), and by the long, cone-shaped apophysis of the epigynum (Fig. 13B). Redescription. Male (‘allotype’), total length 4.9: cephalothorax 1.9 long, 1.8 wide; abdomen 3.0 long, 1.5 wide. Leg I: 45.9 (13.4+0.8+13.1+16.2+2.4), tibia II: 9.4, tibia III: 6.3, tibia IV: 8.1; tibia I L/D: 77. Carapace short, broad and almost circular, ochre, with brown mark broadly connecting to ocular area. Cephalic region raised, with brown marks and pair of brown dots centrally, ocular area dark yellow. Clypeus 0.40, slightly ochre, with yellow marks. Distance AME–AME 0.05. Diameter AME 0.09, ALE 0.15, PME 0.13, PLE 0.14. Chelicerae (Fig. 13D) with pair of black apophyses distally, pair of unsclerotized biforked apophyses proximolaterally and pair of unsclerotized rounded apophyses proximocentrally. Labium light yellow. Endites yellow. Sternum slightly ochre, with numerous irregular yellow marks on it. Femora, patellae and tibiae fawn, with dark rings, metatarsi and tarsi brown. Abdomen cylindrical, pale ochre, dorsum with numerous brown markings. Venter pale brown, without marks. Palps as in Figs. 13F and 13G, bulb with a rounded tile-shaped uncus, appendix with a small branch proximally, trochanter with short ventral apophysis and small retrolateral apophysis. Variation. Tibia I in other male: 12.9. Body length in other male: 4.8. Female: in general very similar to male. Body length 4.9–5.1. Female (holotype), total length 5.1: cephalothorax 1.4 long, 1.4 wide; abdomen 3.4 long, 1.5 wide. Tibia I 8.8. Prosoma shape as in Fig. 13A. Distance AME–AME 0.05.

Pholcus gaoi Song & Ren 1994
No full textPholcus gaoi Song & Ren, 1994 (Fig. 12) Pholcus gaoi Song & Ren 1994: 20, f. 1–7. Song, Zhu & Chen, 1999: 57, f. 23L–O. Diagnosis. Among its close relatives within Pholcus (see the remark of P. alloctospilus), this species is very similar to P. pennatus in the shapes of the palpal bulb and epigynum, both without appendices of palpal bulb (Fig. 12F) and with knob-shaped epigynal apophysis and a sclerotized arch anteriorly of epigynum (Figs. 12B–C). It can be distinguished from the latter by the shape of the tip of the procursus (Figs. 12F–G), by the longer ventral apophysis of the trochanter (Figs. 12E, F–G) and by the widely separated pore plates. Redescription. Male (‘allotype’), total length 5.6: cephalothorax 1.6 long, 1.9 wide; abdomen 3.8 long, 1.6 wide. Leg I: 45.6 (10.8+0.7+11.5+20.2+2.4), tibia II: 7.8, tibia III: 5.5, tibia IV: 6.9; tibia I L/D: 67. Carapace short, broad and almost circular, ochre, with pair of brown marks broadly connecting to ocular area. Cephalic region raised, with brown central stripe, ocular area dark yellow. Clypeus 0.43, slightly ochre, with yellow marks. Distance AME–AME 0.04. Diameter AME 0.10, ALE 0.15, PME 0.13, PLE 0.14. Chelicerae as in Fig. 12D, with pair of black apophyses distally, pair of unsclerotized thumb-shaped apophyses proximolaterally and pair of unsclerotized rounded apophyses proximocentrally. Labium and endites yellow. Sternum slightly ochre, with some irregular yellow marks on it. Femora, patellae and tibiae ochre, with dark rings, metatarsi and tarsi brown. Abdomen cylindrical, pale ochre, dorsum with numerous brown spots on it. Venter pale brown, without marks. Palps as in Figs. 12F and 12G, bulb with triangular uncus and short embolus, without appendix. Trochanter with a long ventral apophysis and a short retrolateral apophysis. Tip of procursus with two spine-shaped apophyses and a hook-shaped projection. Variation. Tibia I in four other males: 10.2, 10.8, 11.0, 11.6. Body length in four other males: 4.9–5.5. Female: in general very similar to male. Body length 5.2–6.0. Female (holotype), total length 6.0: cephalothorax 1.5 long, 1.8 wide; abdomen 4.2 long, 2.8 wide. Tibia I 8.4.

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
