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

No full textEmbora a utilização do corticóide oral não seja indicada no tratamento de manutenção na doença pulmonar obstrutiva crônica, identificamos em nosso ambulatório, um grupo de pacientes que fazem uso desta medicação de forma continuada e, nos quais, todas as tentativas anteriores de retirada da medicação, havia resultado em exacerbação dos sintomas. O objetivo deste estudo foi o de analisar os fenômenos inflamatórios associados à tentativa de redução progressiva do corticóide oral nesses doentes. Avaliamos o escarro induzido de 14 pacientes usuários crônicos de corticóide. Após a avaliação basal, realizada enquanto os pacientes faziam uso de sua dose habitual da medicação (V0), procedemos ao aumento da prednisona a 40 mg por dia, por duas semanas (V1). A seguir, reduzimos progressivamente a dose até que ocorresse uma exacerbação (EXAC), quando a dose de 40 mg de prednisona foi re-introduzida por duas semanas (APÓS). Comparamos os resultados deste grupo aos de um grupo de pacientes portadores de DPOC não-usuários de corticóide oral. Esses pacientes foram avaliados na condição basal (V0), quando exacerbaram (EXAC) e após o tratamento com 40 mg de prednisona, por duas semanas (APÓS). As variáveis analisadas no escarro foram: % de neutrófilos, % de eosinófilos, % de macrófagos, número total de células, interleucinas 4, 6 e 8. Constatamos que o grupo corticóide apresentou um aumento significativo na porcentagem de eosinófilos na exacerbação em relação a V0, e uma redução significativa em APÓS, em relação a EXAC. Isto não ocorreu no grupo não-corticóide. Ao compararmos os dois grupos, observamos que a concentração das interleucinas 4, 6 e 8, foi significativamente mais alta no grupo corticóide em V0 e na exacerbação em relação ao grupo não-corticóide. Quando analisamos o comportamento das interleucinas nas avaliações seqüenciais, dentro de cada grupo, observamos que a interleucina 4 tendeu à elevação na exacerbação, no grupo corticóide, sem atingir, entretanto, significância estatística. As interleucinas 6 e 8 aumentaram significativamente no grupo corticóide na visita APÓS. Concluímos que a retirada progressiva de corticóide oral induz a exacerbação em pacientes com DPOC corticóide-dependentes com um processo inflamatório eosinofílico, que tende à reversão após o aumento da dose do corticóideAlthough in chronic obstructive lung disease the use of oral corticoid is not indicated in the maintenance treatment, we identified a group of patients that make use of this medication continuously. The objective of this study was to analyze the inflammatory phenomena associated to the attempt of progressive reduction of oral corticoids in these patients. We evaluated induced sputum of 14 patients on long-term use of oral corticoids. After the basal evaluation, accomplished while the patients made use of their habitual dose of the medication (V0), we increased the dose of prednisone to 40 mg daily for two weeks (V1). To proceed we reduced the dose progressively until an exacerbation occurred (EXAC), when the dose of prednisone 40 mg daily was reintroduced for two weeks (AFTER). We compared the results to a group of patients with COPD not on use of oral corticoids, that were appraised in the basal condition (V0), when they exacerbated (EXAC) and after the treatment with prednisone 40 mg daily for two weeks (AFTER). The variables analyzed in the sputum were:, % of neutrophils, % of eosinophils, % of macrophages, total number of cells, interleukins 4, 6 and 8. We verified that the corticoid group presented a significant increase in the percentage of eosinophils at the exacerbation in relation to V0, and a significant reduction in AFTER in relation to EXAC. This didn\'t happen in the non corticoid group. When we compared the two groups we observed that the concentration of the interleukins was significantly higher in corticoid group in V0 and at the exacerbation in relation to the non corticoid group. When we analyzed the behavior of the interleukins along the evaluations in each group we observed that interleukin 4 tended to an elevation at the exacerbation in the corticoid group, without reaching statistical significance. Interleukins 6 and 8 increased significantly in the corticoid group in the visit AFTER. We concluded that the progressive reduction of oral corticoid induces exacerbation in patients with COPD on long-term use of prednisone with an eosinophilic inflammatory process that tends to reverse after the increase of the dose of the corticoi

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.
