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
Gekko (Japonicgekko) melli
No full textGekko (Japonicgekko) melli (Vogt, 1922) Chresonymy. Gecko melli — Vogt 1922 Gekko subpalmatus — Pope 1935 (part); Gressitt 1941; Bauer & Günther 1991; Zhao et al. 1999 (part). Gekko melli — Rösler et al. 2005; Rösler & Tiedemann 2007; Yang et al. 2012. Gekko (Japonigekko) melli — Wood et al. 2020 Type materials. Lectotype. ZMB 27659 A, adult male, collected by R. Mell from N. O. Kuangtung [= northeastern Guangdong], PR China; designated by Bauer & Günther (1991). Paralectotype. ZMB 27659 B, juvenile, same data as lectotype; designated by Bauer & Günther (1991). Specimens examined. Two adult male and five adult female specimens. Male SYS r000267 (Fig. 5B 1), collect- ed from Mt. Jiulian, Longnan County, Jiangxi Province, PR China; male SYS r000440, and females SYS r000438, 0439, 0451–0452, 0453 (Fig. 5B 2), collected from Mt. Yinping, Dongguan City, Guangdong Province, PR China. Common name. Mell’s Gecko (in English); meí shì bì hŭ (h氏ŧt). Etymology. The specific name melli is in reference to the collector Rudolf Emil Mell (1878–1970), who was the director of the German-Chinese Middle School at Canton [= Guangzhou City] and collected many animal specimens in Guangdong. His name appeared in Rösler & Tiedemann (2007) as “Robert Mell” due to a typographical mistake (Herbert Rösler, personal communication). Revised diagnosis. (1) medium-sized gecko species, SVL 64.5–80.3 in adults; (2) tubercles on dorsal body, limbs and tail absent; (3) eye moderate, ED/HL ratio 0.21–0.24; (4) rostral moderate, RW/HW ratio 0.20–0.22, RW/RH ratio 1.83–2.13; (5) mental elongate transversely, MW/HW ratio 0.14–0.18, MW/ML ratio 1.11–1.56; (6) nares bordered with rostral, internasals 1–2; (7) interorbital scales between anterior corners of the eyes 34–40; (8) midbody scale rows 148–160; (9) ventral scale rows at midbody 44–46; (10) scales between mental and cloacal slit 171–192; (11) subdigital lamellae on first fingers 9–11, on fourth fingers 9–14, on first toes 10–12, on fourth toes 11–14; (12) fingers and toes with distinct webbing; (13) 9–11 precloacal pores in a continuous row in males; (14) a single postcloacal tubercle on both sides; (14) dorsum greyish white to dark brown, with iregular large dark patches between nape and sacrum; (15) top of head with an small incomplete W-shaped marking, and posteriorly followed by a large inverted W-shaped marking on dorsal neck. (Fig. 6B). Hemipenial characteristics (Fig. 3B): (1) hemipenis clavate, bilobed, densely covered with denticulate-seamed calyces; (2) sulcus spermaticus centrifugal, bifurcate at half of truncus; (3) lateral welt developed, visible from asulcate side, in contact with sulcus lip; (4) calyces extend to lobes and proximal 1/3 of truncus; (5) tongue-like welt weakly developed; (6) apical folds small, arc-shaped, not in contact with each other; (7) a relatively large and rounded area on the asulcate side of the lobe, calyces on this area not well developed (Fig. 3B, Ch 7). Remark. The original description of Gekko (Japonigekko) melli in Vogt (1922) contained no information of locality or designation of type materials. The lectotype and paralectotype was designated by Bauer & Günther (1991) with providing the locality as “N. O. Kuangtung ” [= northeastern Guangdong] while the exact locus is unavailable. The lectotype and paralectotype were redescribed by Rösler & Tiedemann (2007). Currently, this species is recognized from multiple localities in eastern and northeastern Guangdong and neighboring southern Jiangxi (Yang et al. 2012; this study). G. (J.) melli is also expected to occur in southern Fujian which is geographically related to eastern Guangdong, but confirmation requires further vouchers (see Discussion section).Published as part of Lyu, Zhi-Tong, Lin, Chao-Yu, Ren, Jin-Long, Jiang, Ke, Zhang, Yin-Peng, Qi, Shuo & Wang, Jian, 2021, Review of the Gekko (Japonigekko) subpalmatus complex (Squamata, Sauria Gekkonidae), with description of a new species from China, pp. 236-258 in Zootaxa 4951 (2) on pages 247-249, DOI: 10.11646/zootaxa.4951.2.2, http://zenodo.org/record/466397
The mitochondrial genome of Atrocalopteryx melli Ris, 1912 (Zygoptera: Calopterygidae) via Ion Torrent PGM NGS sequencing
No full textThe mitochondrial genome of Atrocalopteryx melli was sequenced and assembled via Next-Generation Sequencing (NGS) and iteratively assembly process with a reference seed. This genome is 15,562 by long and A + T biased (71%), with 37 genes arranged in common order of Odonata. All protein-coding genes are initiated by typical "ATN" codon, and 9 genes are terminated with a complete stop codon, except nad4, nad5, cox2, and cox3, which are terminated with an incomplete codon "T(aa)". The S5 intergenic spacer is absent in this genome, supporting that lacking of S5 as a specific character for damselflies. The A + T rich region of A. melli is 267 bp longer than that of A. atrata. This mitogenome provides new molecular information for understanding of A. melli and Atrocalopteryx
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
New insights into the molecular basis of progressive myoclonus epilepsy: a multiprotein complex with cystatin B
No full textCystatin B is an anti-proteolytic polypeptide implicated in progressive myoclonus epilepsy (EPM1), a degenerative disease of the central nervous system. The knock-out mouse model of the disease shows apoptosis of the cerebellar granule cells. We have identified five recombinant proteins interacting with cystatin B and none of them is a protease. We show that three of these proteins (RACK-1, beta-spectrin and NF-L) co-immunoprecipitate with cystatin B in rat cerebellum. Confocal immunofluorescence analysis shows that the same proteins are present in the granule cells of developing cerebellum, as well as in Purkinje cells of adult rat cerebellum. We propose that a cystatin B multiprotein complex has a specific cerebellar function and that the loss of this function might contribute to the disease in EPM1 patients

Pragmatic Case Studies as a Source of Unity in Applied Psychology
No full textTo unify or not to unify applied psychology: that is the question. In this article we review pendulum swings in the historical efforts to answer this question—from a comprehensive, positivist, “top-down,” deductive yes between the 1930s and the early 60s, to a postmodern no since then. A rationale and proposal for a limited, “bottom-up,” inductive yes in applied psychology is then presented, employing a case-based paradigm that integrates both positivist and postmodern themes and components. This paradigm is labeled “pragmatic psychology” and, its specific use of case studies, the “Pragmatic Case Study Method” (“PCS Method”). We call for the creation of peer-reviewed journal-databases of pragmatic case studies as a foundational source of unifying applied knowledge in our discipline. As one example, the potential of the PCS Method for unifying different angles of theoretical regard is illustrated in an area of applied psychology, psychotherapy, via the case of Mrs. B. The article then turns to the broader historical and epistemological arguments for the unifying nature of the PCS Method in both applied and basic psychology.Peer reviewe
