Leaves opposite, glabrous; lower leaves lanceolate, 1.0– 1.5 cm wide, 4.0– 5.5 cm long, petiole 0.4– 0.9 cm long, mid-vein distinct on the lower surface, lateral veins opaque, base acute, tip acute, margin entire; upper leaves lanceolate, 0.5–1.0 cm wide, 2.0–3.0 cm long, petiole 2–4 mm long, mid-vein distinct on the lower surface, lateral veins opaque, base acute, tip acute, margin entire; bract-like leaves triangular-lanceolate, one or two pairs with setose teeth at base, 4–6 mm wide at base, 10–15 mm long, petiole 2–4 mm long, midvein distinct on the lower surface, base truncate, tip acute-acuminate, sometimes upper leaves and bract-like leaves are indistinctive. Flowers solitary in axils of upper bract-like leaves or congregated into terminal spikes; peduncles 1–2 mm long; calyx tubular-campanulate, 2–3 mm in diameter, 3–5 mm long; lobes 4 with setose tip, upper 2 lobes slightly larger than lower lobes, glabrous or pubescent; corolla tube linear-cylindrical, 2 mm in diameter, 25–30 mm long, slender, expanded upward; limb dilated, bilabiate; upper lip galeate, laterally compressed, with narrow, recurved margin; lower lip slightly longer than upper lip, patent, base 2- plicate, apex 3-lobed; stamens 4, didynamous, enclosed by galea, 10–14 mm long; anthers connivent, held almost vertically in throat, bilocular, thecae with sharply pointed appendages at base; pistil with bilocular ovary; style filiform, curved tip, 25–30 mm long, stigma slightly capitate, entire; ovules 2 per locule. Fruit a capsule, oblong, surface with reticulate veins, ovoid with pointed tip, 7 mm wide, 8–10 mm long, slightly compressed, straight or oblique, loculicidal, apex obtuse or tapered; seeds 3–4, oblong.</p> <p> <b>Distribution and habitat:</b> ― <i>Melampyrum koreanum</i> is known only from the small island Somaemul-do, of Kyeongsangnam-do, South Korea. It grows on open mountain slopes in <i>Pinus thunbergii</i> forest on brown soil. This species is only known from its type locality and only 60 individuals occur in a small area. Therefore, we think that the habitat of this remarkable species should be conserved.</p> <p> <b>Additional specimens examined:</b> ―No previous collections available.</p> <p> <b>Comparison:</b> ― <i>Melampyrum koreanum</i> is closely related to the <i>M. roseum</i> complex (Nakai, 1917; Hong et al., 1998; Yamazaki, 1989; 1993). However, <i>Melampyrum</i> koreanum differs from <i>M. roseum</i> notably by having a longer, more slender corolla tube, longer style, larger capsules with more seeds, fewer setaceous teeth on the bract-like leaves, as well as being more branched and taller. The corolla length and style length of <i>M. roseum</i> are usually 10–15 mm. We examined numerous herbarium specimens of <i>Melampyrum</i> from K, KUN, IBSC, MO, PE and TI. None of the described species of <i>Melampyrum</i> has a corolla tube longer than 20 mm. Therefore, we believe that <i>M. koreanum</i> has the longest corolla tube and style of any <i>Melampyrum</i> species. We observed pollinators from the natural locality of <i>M. koreanum</i> for more than one hour. Hawkmoths of family Sphingidae were the only insects attracted to the <i>M. koreanum</i> flowers. Therefore, we believe that the long corolla tube and style are the adaptive traits to the pollinator. In contrast, the flowers of <i>M. roseum</i> complex are usually visited by bees.</p> <p> <b>Etymology:</b> ―The specific epithet of the new species refers to the endemism in Korea.</p> <p> <b>Phenology:</b> ―Flowering in September to late October; fruiting in early October to early November.</p>Published as part of <i>Kim, Ki-Joong & Yun, Seok-Min, 2012, A new species of Melampyrum (Orobanchaceae) from Southern Korea, pp. 48-50 in Phytotaxa 42</i> on pages 48-50, DOI: 10.11646/phytotaxa.42.1.6, <a href="http://zenodo.org/record/4894831">http://zenodo.org/record/4894831</a>
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
