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
Análise filogenética do gênero Mischonyx Bertkau, 1880, com mudanças taxônomicas e descrição de novas espécies (Opiliones: Gonylepitdae: Gonyleptinae)
No full textBertkau described Mischonyx genus based on a juvenile, in 1880. This holotype is lost, and we can analyze now only the original drawing and the description. Kury, in 2003, considered other genus junior synonyms of Mischonyx (e.g. Ilhaia and Xundarava). Due to revision publications, the genus contained 11 species. However, until this moment, none proposed a phylogenetic hypothesis for the genus to analyze whether it is valid or not and if all described species as Mischonyx represent a natural clade. The objectives of this research are: to propose a phylogenetic hypothesis for Mischonyx based on Total Evidence (TE), to propose taxonomic changes based on the phylogeny and analyse the phylogenetic hypothesis biogeographically as well. I studied 54 individuals, 15 of external group and 39 of internal group. I sequenced seven genes (28S, 12S, 16S, COI, CAD, ITS e H3), totalizing 3742 bp. I raised 124 morphological and genitalic characters. I analysed the dataset under two optimality criteria: Maximum likelihood (ML) and Maximum parsimony (MP). The hypothesis with better biogeographic and morphological background is the TE with ML. I described Three new species: Mischonyx minimus sp. nov. (type locality: Petrópolis, Rio de Janeiro), Mischonyx intervalensis sp. nov. (type locality: Ribeirão Grande, São Paulo) and Mischonyx petroleiros sp. nov (type locality: Nova Iguaçu, Rio de Janeiro). The genus Urodiabunus is junior synonym of Mischonyx. Geraercormobius bresslaui Roewer, 1927, Geraecormobius clavifemur Mello-Leitão, 1927 and Geraecormobius reitzi Vasconcelos, 2005 were transferred to Mischonyx. M. cuspidatus Roewer, 1913 is junior synonym of M. squalidus Bertkau, 1880. By the phylogenetic hypothesis of relationship, Gonyleptes antiquus Mello-Leitão, 1934 (former Mischonyx antiquus) cannot be considered a Mischonyx species, therefore I reestablish the original composition. The new composition for Mischonyx comprises 17 species, with 7 new combinations. I discuss the transformation of character states throughout the phylogeny, the different phylogenetic hypothesis using different datasets and the congruence of evidence between the clades in the phylogenetic hypothesis with the biogeographical hypothesis on Atlantic Forest areas of endemismBertkau descreveu o gênero Mischonyx, baseando-se em um indivíduo juvenil, em 1880. O holótipo está perdido, restando apenas a imagem e a descrição original. Kury, em 2003, considerou vários gêneros como sinônimos juniores de Mischonyx (e.g. Ilhaia e Xundarava). O gênero, até o presente trabalho, possuía 11 espécies, de acordo com trabalhos de revisão publicados anteiormente. No entanto, até o momento, não há nenhuma proposta filogenética para o gênero, afim de saber se ele seria válido ou não e se todas as espécies descritas como Mischonyx representam um agrupamento natural. Os objetivos desta pesquisa foram propor uma hipótese filogenética para Mischonyx, baseado em análise de Evidência Total (TE) e propor mudanças taxonômicas embasadas na filogenia. Estudei 54 indivíduos, 15 de grupo externo e 39 de grupo interno, sequenciei sete marcadores (28S, 12S, 16S, COI, CAD, ITS e H3), totalizando 3742 bp. Levantei 124 caracteres morfológicos e de genitália. Analisei os dados sob dois critérios de otimalidade: Máxima verossimilhança (ML) e Máxima Parcimônia (MP). A hipótese com mais embasamento biogeográfico e morfológico foi a de TE com ML. Descrevi três espécies novas: Mischonyx minimus sp. nov. (localidade-tipo: Petrópolis, Rio de Janeiro), Mischonyx intervalensis sp. nov. (localidade-tipo: Ribeirão Grande, São Paulo), e Mischonyx petroleiros sp. nov. (localidade-tipo: Nova Iguaçu, Rio de Janeiro). O gênero Urodiabunus é aqui considerado sinônimo júnior de Mischonyx. Geraercormobius bresslaui Roewer, 1927, Geraecormobius clavifemur Mello-Leitão, 1927 e Geraecormobius reitzi Vasconcelos, 2005 foram transferidos para Mischonyx. M. cuspidatus Roewer, 1913 é sinônimo júnior de M. squalidus Bertkau, 1880. Pelo relacionamento das hipóteses filogenéticas, Gonyleptes antiquus Mello-Leitão, 1934 (antigo Mischonyx antiquus) não pode ser considerado uma espécie pertencente ao gênero, portanto eu reestabeleci a composição original. Mischonyx tem uma composição nova de 17 espécies, 7 delas com novas combinações. Discuto acerca das transformações de caráteres ao longo da filogenia, sobre as diferentes hipóteses filogenéticas com diferentes datasets e a respeito da congruência dos clados com as hipóteses biogeográficas de áreas de endemismo na Mata Atlântic
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
