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
Livro de imagem: (in)visibilidade na Biblioteconomia brasileira
Full text linkTrabalho de Conclusão de CursoA principal característica do livro de imagem é não ter texto verbal, além disso, pode- se ver que a sua relação com os leitores se dá através da interação e pela leitura de
imagens geradas a partir da construção de narrativas criadas pelas imagens que se
apresentam numa sequência. O livro de imagem é um recurso cada vez mais
importante no auxílio do desenvolvimento da leitura visual, de crianças, jovens e
adultos. Ele pode ser caracterizado como um livro sem texto verbal, constituído
apenas por imagens que se apresentam numa sequência, a qual proporciona a
construção de uma narrativa. Este trabalho teve, como objetivo geral, analisar como a
área de Biblioteconomia brasileira aborda o livro de imagem em sua produção
acadêmica. A pesquisa bibliográfica possibilitou a identificação do que é o livro de
imagem, suas características e sua relação com os leitores. Também identificou
quem são os autores que produzem sobre livro de imagem na área de
Biblioteconomia no Brasil, quantos trabalhos sobre o livro de imagem foram
publicados nesta área e como os mesmos abordam o tema, incluindo sua definição e
propostas metodológicas para uso do livro de imagem. Além disso, a investigação
identificou as potencialidades de uso do livro de imagem na mediação da leitura
apontadas pelos autores, bem como realizou um levantamento de quais são os livros
de imagem mencionados nos trabalhos publicados. Conclui que, embora o livro de
imagem esteja presente dentro de alguns acervos, ele se torna invisível nas salas de
aula, nas bibliotecas e para os profissionais da educação, bibliotecários, auxiliares e
leitores. Este tema ainda é incipiente na área da Biblioteconomia, tendo em vista que
faz dez anos que foi publicado o primeiro trabalho encontrado e, posteriormente,Wordless picture books are told entirely through their illustrations — they are books
without words. It is perceived that its relationship with the lectors takes place through
the interaction and reading of images generated from the construction of narratives
created by the images that are present . A series of sequels Wordless picture book is
an increasingly important resource for the development of visual reading, for children, young people, and adults. The general objective of this work is to analyze how the
Brazilian Librarianship treats the Wordless picture books in its academic production. A
bibliographic investigation allowed us to identify what is the Wordless picture books , his characteristics related to the readers. We also identified that we are the authors
who produce about Wordless picture books in the Brazilian Librarianship area , how
many works about Wordless picture books have been published in this area and how
we approach the topic, including its definition and methodological proposals for the
use of Wordless picture books . . In addition, the investigation identified the potential
use of the Wordless picture books in the mediation of the reading provided by the
authors, as well as a survey of which are the illustrated books cited in the published
works. This research concluded that Wordless picture books is present, within some
collections, it is invisible in classes, libraries and for education professionals, librarians, assistants and lectors. This topic is only incipient in the brazilian librarianship area, considering that the first work found was published a few years ago and later it was
only eight publicationsabout this theme
Mapping scientific dissemination in brazilian scientific articles indexed in the directory of open access journals (DOAJ): a bibliographic review from 2019 to 2023
No full textDissertação (mestrado)Este estudo teve como objetivo mapear a produção científica brasileira sobre divulgação científica, disponível no Directory of Open Access Journals (DOAJ), no contexto da ciência aberta. Nos objetivos específicos buscamos : “a” pesquisar os artigos que versam sobre divulgação científica no Brasil indexados no DOAJ, os objetivos “b” e “c” trata-se de um estudo bibliométrico, através das leis de Lotka e Zipf e a colaboração científica e o objetivo “d” uma análise qualitativa. Nos resultados, foram recuperados 77 artigos, dos quais 62 foram selecionados para o estudo. A análise bibliométrica revelou a distribuição dessas publicações ao longo dos cinco anos, destacando 2022 como o ano com o maior número de artigos publicados, totalizando 17. Dentre os 62 artigos selecionados, 30 foram produzidos em coautoria, envolvendo dois autores, enquanto dois artigos contaram com a colaboração de seis autores. A pesquisa identificou 47 instituições brasileiras, sendo que seis delas se destacam por contar com um número significativo de autores afiliados, variando entre 5 e 11. A maior concentração de autores está na região Sudeste, e com a maior concentração de revistas situada na região Sul, foi aRevista Insignare Scientia. Foram identificados 135 descritores, com destaque para áreas predominantes como Química, Física, Biologia, História, Filosofia, além de Educação em Ciências e Ensino de Ciências. Como considerações, destaca-se que a análise qualitativa indicou que a divulgação científica é um campo diverso e em constante expansão, com múltiplas abordagens e formatos que visam aproximar o público da ciência.This study aimed to map Brazilian scientific production on scientific dissemination, available in the Directory of Open Access Journals (DOAJ), in the context of open science. Objectives “b” and “c” are a bibliometric study, using Lotka and Zipf's laws and scientific collaboration, and objective “d” is a qualitative analysis. In the results, 77 articles were retrieved, of which 62 were selected for the study. The bibliometric analysis revealed the distribution of these publications over the five years, highlighting 2022 as the year with the largest number of articles published, totaling 17. Among the 62 articles selected, 30 were produced in co-authorship, involving two authors, while two articles had the collaboration of six authors. The research identified 47 Brazilian institutions among the affiliated authors, six of which stand out for having a significant number of authors, ranging from 5 to 11. The largest concentration of authors is in the Southeast region, and the Insignare Scientia Journal was the most productive, with the largest concentration of journals located in the South region. 135 descriptors were identified, with emphasis on predominant areas such as Chemistry, Physics, Biology, History, Philosophy, as well as Science Education and Science Teaching. As considerations, the qualitative analysis indicated that scientific dissemination is a diverse and constantly expanding field, with multiple approaches and formats that aim to bring the public closer to science
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
