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
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
Efeito da aplicação de fosfopeptídeo de caseína-fosfato de cálcio amorfo (CPP-ACP) associado ao protocolo adesivo na resistência de união de dois sistemas restauradores
No full textO objetivo desse estudo foi avaliar a resistência de união ao teste de microcisalhamento de dois sistemas restauradores com ou sem a aplicação prévia de fosfopeptídeo de caseína-fosfato de cálcio amorfo (CPP-ACP) em substrato dentinário. Para tanto, foram utilizados dois sistemas adesivos, Clearfil SE Bond (Kuraray) e FiltekTM P90 (3M ESPE); e duas resinas compostas micro-híbridas, uma a base de metacrilato FiltekTM Z250 A2 (3M ESPE) e outra de baixa contração de polimerização a base de silorano FiltekTM P90 A2 (3M ESPE). A oclusal de 28 terceiros molares humanos hígidos (n=7) foi desgastada com lixa dágua #360 (Norton) em politriz APL-4 (Arotec), sob refrigeração constante com água, até que toda a superfície estivesse complemente em dentina. Previamente ao protocolo adesivo, a dentina exposta foi polida com lixa #600 durante 60s para a padronização da smear layer, sendo restaurados com um dos dois sistemas restauradores: Clearfil SE Bond + FiltekTM Z250 e sistema restaurador FiltekTM P90, com ou sem a aplicação prévia da pasta contendo CPP-ACP; e fotoativados com o aparelho de fotoativação Bluephase 16i (Vivadent) com o tempo de fotoativação recomendado pelos fabricantes. Para o teste de microcisalhamento foi utilizada uma máquina de ensaio universal EZ Test (Shimadzu). Os dados obtidos foram submetidos à análise de variância. O resultado mostrou que não houve diferença estatisticamente significante nos valores de resistência de união entre os diferentes sistemas restauradores avaliados bem como na aplicação ou não do CPP-ACP, com valores variando entre 5,22 ± 1,48 (P90 sem CPP-ACP) e 7,23 ± 2,96 (Clearfil + Z250 com CPP-ACP). Pode-se concluir que a aplicação de fosfopeptídeo de caseína-fosfato de cálcio amorfo na dentina previamente ao protocolo adesivo não influenciou na resistência de união dos sistemas restauradores testados.This study evaluated the effect of the application of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) previously to procedures on the microtensile bond strength of two restorative systems at dentin substrate. For that it was used two adhesive, Clearfil SE Bond (Kuraray) and FiltekTM P90 (3M ESPE); and two micro-hybrid restorative system, methacrylate-based FiltekTM Z250 A2 (3M ESPE) and low polymerization shrinkage silorane-based. Twenty eight occlusal surface of third molars (n=7) was worning out with sandpaper #360 (Norton) in polishing machine APL-4 (Arotec), under constant cooling water until all the surface was completely in dentin tissue. Previously to the adhesive system, the exposed dentin was polish with sandpaper #600 during 60 seconds to the standardization of smear layer, being restored with two restorative system Clearfil SE Bond + FiltekTM Z250 and FiltekTM P90, with or without the use of CPP-ACP and light curing with the photoactivation device Bluephase 16i (Vivadent) with time of polymerization recommended by the manufactured. To the microshear test was used a universal testing machine EZ Test (Shimadzu). The data were subjected to analysis of variance. The result showed no statistically significant difference in bond strength values between the different restorative systems evaluated as well as whether or not the CPP-ACP, with values ranging from 5.22 ± 1.48 (P90 without CPP-ACP) and 7.23 ± 2.96 (Clearfil + Z250 with CPP-ACP). It can be concluded that the application of casein phosphopeptide-amorphous calcium phosphate on dentin prior to adhesive protocol did not influence the bond strength of restorative systems tested
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.
