Campylotropis luquanensis B. Xu & L. S. Jiang 2021, sp. nov.
No full textCampylotropis luquanensis B.Xu & L.S.Jiang, sp. nov. (Figs. 1 & 2). Type:— CHINA. Yunnan: Kunming City, Luquan County, Zhongping Town, elev. 1150–1200 m, growing on the hill slopes, 8 January 2019, Xu Bo 01495 (holotype CDBI!; isotypes CDBI! KUN!). Diagnosis:—This new species is similar to Campylotropis grandifolia and C. henryi in distinctly branchlets quadrangular, petioles abaxially angled and often narrowly winged along both sides, stipels absent, leaflets adaxially glabrous, bracteoles usually caducous, but it differs from both in stipules obviously smaller, leaflets abaxially sparsely pubescent obovate to obcordate, inflorescences shorter, and legume with obvious net-veins. Moreover, it is also distinguished from them by usually with 2–4 axillary racemes densely clustered on the second-year brachyblasts, and by its flowering before leaves (hysteranthous). Shrubs, erect, 1.5–2 (–3) m tall. Branches distinctly irregular quadrangular, with sparse short appressed hairy. Leaves pinnately 3-foliolate, (2.5–) 4–8 (–10) cm; stipules triangular-lanceolate to lanceolate, rarely ovate-triangular, 1.5– 3.5 mm, densely pubescent; stipels absent; petioles abaxially angled and narrowly winged along both sides, densely pubescent, 0.5–2.5 cm; leaflets obovate to obovate-cordate, rarely elliptic or ovate, terminal one 1.5–5 (–7) × 1.5–4.5 cm, adaxially glabrous, abaxially usually sparsely appressed pubescent particularly on veins and margin, midveins distinctly raised, densely appressed pubescent, apex retuse and mucronate, rarely obtuse to rounded, base suborbicular, broadly cuneate, rarely rounded. Inflorescences usually axillary racemose or rarely paniculate, 2–5 cm, usually 2–4 axillary racemes densely clustered on the second-year brachyblasts, peduncles 0.4–1.6 cm, with ± dense appressed to ascending short hairs and sometimes sparsely glandular hairs; pedicels 4–7 mm, rachis and pedicels densely spreading pubescent and glandular hairs. Bracts lanceolate or ovate-lanceolate, 1–2 mm, persistent or caducous, bracteoles usually caducous, linear lanceolate, 1–1.5 mm. Calyx campanulate, 3.5–5 mm, with dense appressed short hairs, tube 1.5–2.8 mm; lobes narrowly triangular and acuminate, 2.2–3 mm, lower lobes narrower and longer than upper and lateral ones, upper lobes connate. Corolla purple; standard elliptic to widely ovate, rarely suborbicular, 9–12 × 6.5–8 mm, apex obtuse, claw ca. 1.5 mm; wings obovate-elliptic, 9.5–11.5 × 3.3–3.7 mm, apex rounded, auricle ca. 1 mm, claw 2.2–2.7 mm; keel incurved, 10–11 × 3–3.5 mm, claw 2–2.5 mm, auricle ca. 0.5 mm. Stamens diadelphous, 8–10 mm, staminal tubes 6–8 mm, free part of filaments 2–3 mm. Pistils 10–11.5 mm; ovary dense puberulent, upper margin with densely ciliate; style incurved, 7.5–8 mm. Legume obliquely ovate to obliquely elliptic, light brown, 6–8 × 3–3.5 mm, obvious brown net-veins; apex rostrate-apiculate, sparsely pubescent. Seeds reniform, ca. 3 × 2 mm. Phenology: —Flowering before leaves, from December to next March, fruiting from March to April. Distribution and habitat: — Campylotropis luquanensis is known only from Luquan County in Yunnan Province and Leibo County in Sichuan Province (Fig. 3). It was observed to grow along roadsides, streams, and thickets in hot dry valleys at elevations of 850–1200 m. Conservation status: —Without extensive exploring the similar habitats in Southwest China, we assessed the conservation status of Campylotropis luquanensis as Data Deficient (DD) according to the IUCN (2019). Etymology: —The specific epithet luquanensis refers to the county name, Luquan, where the type locality administratively belongs to. Additional specimens examined: — CHINA. Yunnan: Luquan County, Zhongping Town, elev. ca. 1200 m, 1 April 2009, E . D. Liu 2087 (KUN); Sichuan: Leibo County, Shanlinggang Town, elev. ca. 865 m, 14 April, 2019, Q . Yu et al. CIBYQ056 B004 (CDBI). Taxonomic notes: —In addition to the diagnosis, detailed morphological comparison among Campylotropis luquanensis, C. grandifolia and C. henryi is summarized in Table 1.Published as part of Jiang, Li-Sha & Xu, Bo, 2021, Campylotropis luquanensis (Fabaceae: Papilionoideae), a new species from Southwest China, pp. 114-118 in Phytotaxa 524 (2) on pages 114-116, DOI: 10.11646/phytotaxa.524.2.6, http://zenodo.org/record/564209
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
