Sedum triangulisepalum T. S. Liu & N. J. Chung ex T. C. Hsu & S. W. Chung 2022, sp. nov.
No full text<p> <i>Sedum triangulisepalum</i> T.S. Liu & N.J. Chung ex T.C. Hsu & S.W. Chung, <i>sp. nov.</i></p> <p> [“ <i>Sedum triangulisepalum</i> T.S. Liu & N.J. Chung (1977: 21, as <i>triangulosepalum</i>)”, <i>nom. inval.</i>; “ <i>Sedum triangulisepalum</i> T.S. Liu & N.J. Chung ex H.W. Lin (1999: 102, as <i>triangulosepalum</i>)”, <i>nom. inval.</i>; “ <i>Sedum triangulisepalum</i> T.S. Liu & N.J. Chung ex S.W. Chung ” in Chen <i>et al.</i> (2017: 329, as <i>triangulosepalum</i>), <i>nom. inval.</i>].</p> <p> <b>Type:</b> — TAIWAN. Hualien County: Hsiulin Township, Lo-ma-wan Shan, 1800 m elev., 15 June 1973, <i>N.J. Chung 280</i> (holotype: NTUF!, barcode: F00008307; isotypes: NTUF!, eight sheets, barcodes: F00008308–F00008315).</p> <p> <b>Diagnosis:</b> — <i>Sedum triangulisepalum</i> is similar to <i>S. truncatistigmum</i> T.S. Liu & N.J. Chung (1977: 23) in sharing epiphytic life-form, alternate and ±flattened leaves and fused calyx, while the former is readily distinguished in having longer calyx (1.5–2.0 vs. 0.8–1.0 mm) that are only fused at the base (vs. nearly entirely fused).</p> <p> <b>Morphological descriptions and illustrations:</b> —This species has been described by Liu & Chung (1977: 21) and illustrated by Tang & Huang (1989: 27, pl. 15, as <i>Sedum microsepalum</i>), Chen <i>et al.</i> (2017: 329) and Ito <i>et al.</i> (2017: 11, fig. 1D).</p> <p> <b>Distribution and ecology:</b> — <i>Sedum triangulisepalum</i> is endemic in Taiwan, where it occurs in the northern and eastern portions of the main island and usually grows on tree trunks in montane cloud forests at 500–2000 m elev. (Liu & Chung 1977; Chen <i>et al.</i> 2017; Ito <i>et al.</i> 2017).</p> <p> <b>Etymology:</b> —The specific epithet is composed of two Latin elements: <i>triangulus</i>, triangular, and <i>sepalum</i>, sepal, referring to its triangular calyx lobes. It should be spelt as “ <i>triangulisepalum</i> ” instead of “ <i>triangulosepalum</i> ” as originally published by Liu & Chung (1977) according to Art. 60.10 of the ICN.</p> <p> <b>Note:</b> —Two gatherings, “ <i>Suzuki s.n.</i> ” collected from Wulai and “ <i>Chuang 280</i> ” collected from Lomawanshan, were cited under <i>Sedum triangulisepalum</i> by Liu & Chung (1977), and “ <i>Chuang 280</i> ” is presumably a typo of “ <i>Chung 280</i> ” since the “ <i>N.J. Chung 280</i> ” gathering, collected by the second original author and currently preserved in NTUF, matches well with the data given in the original publication (Liu & Chung 1977). There are nine duplicates of <i>Chung 280</i>, including one (barcode: F00008307) labelled as “ holotype ” and the others (barcodes: F00008308–F00008315) as “isotype”. Although these labels could not be archived as the legitimate designation of types as they are not effectively published (see Art. 7.10 of the ICN), they supposedly reflect the original author’s intention and are thus adopted here. Images of all type materials are available in the “Plants of Taiwan ” database [http://tai2.ntu.edu.tw].</p>Published as part of <i>Hsu, Tian-Chuan & Chung, Shih-Wen, 2022, Validation of the name Sedum triangulosepalum (Crassulaceae), pp. 215-216 in Phytotaxa 547 (2)</i> on page 215, DOI: 10.11646/phytotaxa.547.2.10, <a href="http://zenodo.org/record/6571375">http://zenodo.org/record/6571375</a>
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
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
Concentration in Knowledge Output: A case of Economics Journals
Full text linkThis paper assesses the degree of author concentration in seven economics journals, which were published in India during 1990-2002. To measure the degree of author concentration, Lotka's Law was used. Moreover, we also make an exploratory analysis of the geographic, economics subfield and institutional concentration in 704 economics journals. An important finding of this paper is that specialized journals in the sample report the highest degree of author concentration. This result is quite similar to the findings by Cox and Chung (1991). Furthermore, there are several instances showing that the journals lean towards certain norms; this may affect the flow of innovative ideas into economics. We conclude that a knowledge activity, involving the high degree of concentration and a biased publication process, may affect the flow of new ideas into the discipline.Concentration, Lotka's Law
