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
Medical decision making: Microsimulation versus cohort modelling for assessing type 2 diabetes treatments
No full textType 2 Diabetes Mellitus (T2DM) is associated with high rates of mortality and complications, making it challenging to evaluate new treatments. Health economic models, such as cohort models and microsimulations, are currently available to evaluate new medications. However, it remains unclear which type of modelling is more suitable for evaluating T2DM treatments. Tirzepatide is a new treatment that has demonstrated promising results for glycaemic control in diabetic patients requiring insulin. The aim of this study is to compare the differences between microsimulation and cohort modelling when assessing tirzepatide for treating type-2 diabetes
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
Coccoglypta arbusticola Páll-Gergely & Hunyadi & Chen & Lyu 2019, n. comb.
No full textCoccoglypta arbusticola (Deshayes, 1870) n. comb.

TYPE MATERIAL EXAMINED. — China. Moupin [Muping Zhen, Sichuan], l’Abbé David, 1869, syntype, MNHN-IM-2000-34192. TYPE LOCALITY. — “Principauté de Moupin, Thibet oriental” (from title). REMARKS This species has previously been assigned to the genus Bradybaena, however it surely does not belong to that genus in its present concept. The type species of Bradybaena, B. similaris (Rang, 1831), has a small (c. 1 cm), fragile shell without any distinctive sculpture. However, C. arbusticola n. comb. is larger (shell diameter of syntype: 24.5 mm), and has a thick, finely mamillated shell, reminiscent of those of Coccoglypta. We have examined the lectotype of Eulota arbusticola chrysomphala Möllendorff, 1899 (see Möllendorff, 1899: 70 and Yen, 1939: 135) in the Senckenberg Museum (China: W. Sy-tshuan, Fu-bien-ho, SMF 9159, figs 6E-H). It had a light brown, very finely wrinkled and extremely finely spirally grooved shell, without any signs of mamillae. The aperture is also comparatively much larger in chrysomphala than in arbusticola. Thus, “ Bradybaena ” chrysomphala and Coccoglypta arbusticola n. comb. cannot be subspecies of the same species and must be considered as two distinct species. The single shell in the Senckenberg Museum identified as B. arbusticola and figured by Yen (1939) has a narrower umbilicus and more rapidly growing whorls than the type, and there are also no signs of a mamillated sculpture. Therefore, we here exclude it from the present species. Its true identity remains unknown. Furthermore, the shell figured in Chen & Zhang (2004) also belong to another species, because it has a narrower umbilicus, a dark spiral band, and a more strongly expanded peristome.Published as part of Páll-Gergely, Barna, Hunyadi, András, Chen, Zhe-Yu & Lyu, Zhi-Tong, 2019, A review of the genus Coccoglypta Pilsbry, 1895 (Gastropoda: Pulmonata: Camaenidae), pp. 595-608 in Zoosystema 41 (29) on pages 602-604, DOI: 10.5252/zoosystema2019v41a29, http://zenodo.org/record/372611
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
The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
Contribution of Information and Communication Technology (ICT) in Country’S H-Index
No full textThe aim of this study is to examine the effect of Information and Communication Technology (ICT) development on country’s scientific ranking as measured by H-index. Moreover, this study applies ICT development sub-indices including ICT Use, ICT Access and ICT skill to find the distinct effect of these sub-indices on country’s H-index. To this purpose, required data for the panel of 14 Middle East countries over the period 1995 to 2009 is collected. Findings of the current study show that ICT development increases the H-index of the sample countries. The results also indicate that ICT Use and ICT Skill sub-indices positively contribute to higher H-index but the effect of ICT access on country’s H-index is not clear
Inocellia occidentalis Liu & Lyu & Aspöck & Aspöck 2018, sp. nov.
No full textInocellia occidentalis sp. nov. (Figs. 1–7) Diagnosis. The species is characterized in the male by the fused gonocoxites 11 (gonarcus) medially with a pair of digitiform projections, the feebly developed gonostylus 9, and the reduction of bristles on endophallus. Description. Male. Forewing length 8.2 mm. Head subquadrate, black, clypeus reddish brown, vertex with a pair of indistinct yellowish brown vittae medially and broad yellowish brown markings laterally. Antennal sclerite (torulus) pale yellowish brown; antenna pale brown, but scape, pedicel and proximal four flagellomeres yellow. Mouthparts blackish brown except for maxillary palps pale yellowish brown. Thorax blackish brown; anterior margin of pronotum yellow; meso- and metanota each with a tiny yellowish marking on scutellum, metanotum anteromedially also yellow. Legs yellow with yellowish setae. Wings hyaline, pterostigma and veins brown. RP with one forked vein and one simple vein running to wing margin. MA distally bifurcated. Abdomen blackish brown, venter slightly paler; each pregenital segment with a narrow yellowish transverse marking on posterior margins of tergum and sternum. Gonocoxite 9 shell-like, suboval, much wider than long, distally feebly curved inward; gonostylus 9 present on subdistal portion of inner side, small tubercle-form, with a few stiff bristles. A tuft of bristles present close to and anteriad gonostylus 9. Basal parts of gonapophyses 9 (pseudostyli) paired and foliate. Complex of fused gonocoxites, gonapophyses, and gonostyli 10 small, proximal portion flattened and divided into a pair of lobes, distal projection curved dorsad with tip slightly notched. Fused gonocoxites 11 (gonarcus) shield-like, in caudal view dorsal margin laterally produced dorsad, ventral margin arcuately convex, median portion with a pair of slender and digitiform projections. Endophallus short, with only two bristles on dorsal surface. Ectoproct ovoid in lateral view. Hypandrium internum small, lobes narrow. Female. Unknown. Type material. Holotype ♂, CHINA: Sichuan Prov., Daofu, Gechang, Gechang, Zewola [30°50.191′N, 101°16.872′E], 3438 m, 24.VI.2016, Yejie Lin (CAU). Distribution. China (Sichuan). Etymology. The specific epithet ‘ occidentalis ’ refers to the distribution of the new species in western China. It is an adjective in the nominative feminine singular. Remarks. The new species belongs to the I. crassicornis group based on the male gonocoxite 9, which is much wider than long. The new species appears to be closely related to Inocellia digitiformis Liu, H. Aspöck, Yang & U. Aspöck, 2010 in having similar male gonocoxites 11 (gonarcus) with a pair of digitiform projections. However, the new species can be distinguished from I. digitiformis by the feebly developed male gonostylus 9 [male gonostylus 9 is digitiform, distally with bristles in I. digitiformis], the shape of male fused gonocoxites 11 [arcuately convex in I. occidentalis sp. nov. but distinctly produced in I. digitiformis], the position of projections on fused gonocoxites 11 [present on median portion in I. occidentalis sp. nov. but near dorsal margin in I. digitiformis], and the reduction of bristles on male endophallus [endophallus with two pairs of bristle tufts in I. digitiformis].Published as part of Liu, Xingyue, Lyu, Yanan, Aspöck, Horst & Aspöck, Ulrike, 2018, Discovery of a new species of Inocelliidae (Insecta: Raphidioptera) in an altitude of nearly 3500 m in China, pp. 585-589 in Zootaxa 4471 (3) on pages 586-588, DOI: 10.11646/zootaxa.4471.3.10, http://zenodo.org/record/143985
