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
Fotografia e infância: o universo simbólico das “lembrancinhas” de crianças e suas representações
Get PDFThe photographic resource emerged in the nineteenth century promoted one of the most significant symbolic reconstructions of the world. This is due to the fact that for the first time the man could achieve "perfection" of their representation. This will influence the way we visualize the man himself and the surrounding society. The photograph, now something trivial to contemporary society extremely linked frequent technological innovations, has many unexplored properties. The objective of this work is to analyze the narrative discourse in photographs and their representations of childhood. The usual souvenir photo to relatives, especially for the godparents of children remains common practice, albeit in different ways. Today, the "souvenirs" cameras are being replaced by other technological resources, among them, perhaps the most popular e-mail. If this factor promoted on the one hand, the increased circulation of the world images also commonplace by another workman merely as illustrative of the written text. The imagery language carries a number of meanings, translating times and directions, offering other possibilities of interpretation beyond the written text.O recurso fotográfico, surgido no século XIX, promoveu uma das mais significativas reconstruções simbólicas do mundo. Isso se deve ao fato de que pela primeira vez o homem conseguia atingir a “perfeição” de sua representação. Isto influenciaria o modo como o homem visualizaria a si e a sociedade circundante. A fotografia, hoje algo trivial para a sociedade contemporânea extremamente vinculada às frequentes inovações tecnológicas, possui muitas propriedades pouco exploradas. Assim, o objetivo deste trabalho é analisar os discursos narrativos em fotografias e suas representações sobre a infância. O costume da lembrança fotográfica aos parentes, em especial para os padrinhos de crianças, permanece como uma prática corrente, ainda que de diferentes formas. Atualmente, as “lembrancinhas” fotográficas vão sendo substituídas por outros recursos tecnológicos, entre eles, talvez o mais popular, os e-mails. Se este fator promoveu, por um lado, a maior circulação de imagens no mundo por outro também a banalizou como mero artífice ilustrativo do texto escrito. A linguagem imagética carrega uma série de significados, traduzindo tempos e sentidos, oferecendo outras possibilidades de interpretação para além do texto escrito
Modelos de história natural: as imagens dos bustos raciais nos museus escolares
No full textEm levantamento realizado em museus localizados em espaços escolares na Região Metropolitana de Porto Alegre localizou-se a presença de imagens representativas dos diferentes tipos raciais humanos no museu escolar do antigo Instituto São José – La Salle/Canoas (RS) e no Museu Metodista de Educação do Colégio Americano (RS). O objetivo deste trabalho é verificar e analisar os diferentes usos destes materiais no ensino, e suas possíveis relações com o método intuitivo. Problematizando o giro conceitual destes modelos de gesso na história da educação brasileira, evidencia-se que estes foram tendência de ensino sobre a espécie humana e suas diferentes raças, bem como aportes de teorias racialistas correntes na época. Como resultados parciais, descobriu-se que estes bustos também podem ser verificados nos acervos de escolas de grandes centros como o Rio de janeiro e Lisboa. No caso português essas peças remontam o século XIX. No Rio de Janeiro, o Colégio Pedro II, considerado um modelo a ser seguido pelas demais escolas nacionais, adquiriu peças semelhantes entre as décadas de 1920 e 1930, o que demonstra certa tendência do uso destes objetos no ensino escolar
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
