The Lychnophora Granmogolensis (asteraceae-vernonieae) Species Complex: Two New Species And Comments On The Identity Of Lychnophora Granmogolensis
No full textLychnophora rupestris and Lychnophora nanuzae are two new endemic species from quartzitic, rocky-field vegetation in Brazil. These new species are described and illustrated, and their affinities discussed. They are similar to L. granmogolensis, suggesting the definition of a species complex. The L. granmogolensis species complex can be recognized by imbricate leaves, ericoid, revolute margins, pungent apex with mucron, 1-3 flowers per capitulum, and outer pappus series free or partially fused. Lychnophora granmogolensis is a poorly known species from the Diamantina plateau in northern Minas Gerais State, and Chapada Diamantina (Bahia) in the Espinhaço Mountain Range. To clarify the application of the name L. granmogolensis, that species is also described and illustrated, and affinities are discussed. © Copyright 2014 by the American Society of Plant Taxonomists.393988996Baker, J.G., Compositae.

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
Cytotaxonomy Of Lychnophoriopsis Sch.bip. And Paralychnophora Macleish Species (asteraceae: Vernonieae: Lychnophorinae)
No full textThe genera Lychnophoriopsis and Paralychnophora are endemic to Brazilian 'campo rupestre' in the States of Minas Gerais and Bahia. To analyse the status of the cytotaxonomy of these genera, we carried out chromosome counts on several species. Two chromosome numbers were obtained for four species of Paralychnophora: 2n = 36 and 2n = 38. For three species of Lychnophoriopsis, only 2n = 36 was observed. The chromosome size (1.0-2.58 μm) and morphology (mainly metacentric, with some submetacentric) were analysed in four species of Paralychnophora and showed relative constancy. © 2007 The Linnean Society of London.1541109114Coile, N.C., Jones, S.B., Lychnophora (Compositae: Vernonieae), an endemic genus to the Brazilian planalto (1981) Brittonia, 33, pp. 528-542Dematteis, M., Estudios cromosomicos en especies Argentinas de Vernonia (Asteraceae) (1996) Bonplandia, 9, pp. 103-110Dematteis, M., Chromosome studies of some Vernonia species (Asteraceae) (1998) Genetics and Molecular Biology, 21, pp. 381-385Dematteis, M., Cytotaxonomic analysis of South American species of Vernonia (Vernonieae: Asteraceae) (2002) Botanical Journal of the Linnean Society, 139, pp. 401-408Dematteis, M., Fernández, A., Karyotypes of seven South American species of Vernonia (Vernonieae, Asteraceae) (1998) Cytologia, 63, pp. 323-328Dematteis, M., Fernández, A., Chromosome studies on nine South American species of Vernonia (Vernonieae, Asteraceae) (2000) Caryologia, 53, pp. 55-61Galiano, N.G., Hunziker, J.H., Estudios cariologicos en Compositae, IV.
