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
Superação legislativa e a última palavra provisória: expressões de diálogo institucional ou de supremacia entre poderes?
No full textThe article investigates the limits and forms of interaction between the Federal Supreme Court (STF) and the National Congress in Brazil, focusing on legislative override and the theory of the last provisional word. The problem lies in understanding whether such phenomena express an effective institutional dialogue or reveal disputes over interpretive supremacy of the Constitution. The aim is to critically examine these categories in the context of the Brazilian constitutional model, which is marked by the absence of binding legislative decisions by the STF in abstract constitutional control. The method adopted was a literature review and critical analysis of the topic based on the Brazilian experience, considering both Brazilian and foreign authors. It is concluded that legislative override does not constitute institutional dialogue, but rather a stage of the constitutional process linked to legislative independence and conditioned by political factors, so that the mechanisms of interaction between powers are contingent and do not guarantee a dialogical model. The theory of the last provisional word affirms the absence of an interpretative monopoly and offers a dynamic vision of constitutional interpretation, defined by the power challenged last, although it does not resolve issues pointed out by critics such as interpretative anarchy or the absence of definitive criteria for closing constitutional disputes.O artigo investiga os limites e as formas de interação entre o Supremo Tribunal Federal (STF) e o Congresso Nacional no Brasil, com foco na superação legislativa e na teoria da última palavra provisória. A problemática reside em compreender se tais fenômenos expressam um efetivo diálogo institucional ou se revelam disputas por supremacia interpretativa da Constituição. O objetivo é examinar criticamente essas categorias no contexto do modelo constitucional brasileiro, marcado pela ausência de vinculação do Legislativo às decisões do STF em controle abstrato. O método adotado foi a revisão bibliográfica e análise crítica do tema a partir da experiência brasileira, considerando autores nacionais e estrangeiros. Conclui-se que a superação legislativa não se configura como diálogo institucional, mas como uma etapa do processo constitucional vinculada à independência do legislativo e condicionada a fatores políticos, de forma que os mecanismos de interação entre os poderes são contingenciais e não garantem um modelo dialógico. Já a teoria da última palavra provisória afirma a ausência de monopólio interpretativo e oferece uma visão dinâmica da interpretação constitucional, definida pelo poder desafiado por último, embora não resolva questões apontadas pelos críticos como a anarquia interpretativa ou a ausência de critério definitivo para encerrar disputas constitucionais
