Lectotypification of the name Gleadovia ruborum Gamble & Prain (Orobanchaceae)
No full textThe genus Gleadovia was described by J.S Gamble and D. Prain (1900: 488) including a single species, G. ruborum Gamble & Prain (1900: 489) on the base of plants collected in 1898 from Bodyar, Jauansar in N.W. Himalaya. The genus is represented now by 3 species distributed in India and China. These species are: G. ruborum Gamble & Prain (India and China), G. mupinense Hu (1939: 2) (China) and G. banerjiana Deb (1956: 799) (India). G. ruborum is characterized by ovate or oblong leaves, 3- to several pedicelate flowers clustered at stem apex, obovate bract, spatulate-oblanceolate bracteoles, a tubular-campanulate calyx funnelform upward, much shorter than corolla, to 1.8 cm in diam., comparatively shorter pedicel, to 2.5 cm long and by corolla glabrous abaxially, villous adaxially (J.S. Gamble 26949-K! (K000999865, K000999866); CAL! (Acc. No. 329959)), whereas G. mupinense is characterized by oblong-lanceolate or lanceolate leaves, 3- to several pedicelate flowers borne on upper part of stem, oblong-lanceolate bract, linear-lanceolate bracteoles, a tubular calyx slightly enlarged upward, much shorter than corolla, to 1.2 cm in diam., longer pedicel, to 9 cm long and by densely villous corolla lobes on both sides (T.T. Yu 2189-PE! (PE - 1643589-00032337)), while G. banerjiana is characterized by lanceolate or ovate-lanceolate, spatulate leaves, 1–3 subsessile, ebracteate, ebraceolate flower(s) borne at the stem apex, a spathaceous calyx more or less equal to corolla, to 4.5 cm in diam. and densely hairy corolla lobes inside (D.B. Deb 2247A-CAL! (Acc. No. 329964)). When Gamble and Prain (1900) described G. ruborum, they mentioned in the protolouge the collections of J.S. Gamble, F. Gleadow, J.F. Duthie and Duthie’s collectors collected in 1898 from Bodyar, Jaunsar in N.W. Himalaya. Thus the cited authentic collections consist of several elements collected by different collectors. Therefore it warrants the typification under Art. 9.5 of the International Code of Nomenclature (McNeill et al. 2012). Hence a lectotype is designated here from the original collections.</jats:p
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
Notes on recollection and extended distribution of Rhynchotechum alternifolium C.B.Clarke (Gesneriaceae) in Eastern Himalaya, Bhutan
Full text linkRhynchotechum alternifolium C.B.Clarke, a Gesneriaceae plant taxon earlier known from India and Myanmar, is reported here as an extended distribution to Bhutan. In India, earlier it was reported from Arunachal Pradesh, Assam, Manipur and Nagaland. The last observation of this taxon was in 1962 from Myanmar. During recent field exploration (2015), it is once again reported from Nagaland. Based on herbaria records, it is also recorded from Sikkim Himalaya. Brief taxonomic description along with photographic illustration and distribution map of the taxon is provided. Further investigation is required in the eastern Himalaya and North-eastern region of India to ascertain its present population status as well as IUCN status for conservation point of view.INTERNATIONAL JOURNAL OF ENVIRONMENTVolume-6, Issue-2, Mar-May 2017, Page: 1-8</p

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
