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
Produção científica do Brasil : relações entre o acesso aberto à informação científica e a política de financiamento público para a publicação de artigos mediante o pagamento de Article Processing Charge (APC)
Get PDFA Article Processing Charge (APC), ou taxa de processamento de artigo, como um modelo de negócio, é empregado para a publicação de revistas científicas de Acesso Aberto (AA) e híbridas. Esta pesquisa, de abordagem quantitativa e de tipologia exploratória e descritiva, analisou a produção científica brasileira em Acesso Aberto mediante o pagamento de APC e a política de fomento público. Os objetivos específicos foram: verificar os tipos de financiamento ofertados pelas agências de fomento brasileiras para a publicação de artigos mediante o pagamento de APC; caracterizar a produção científica brasileira em AA publicada no período 2012-2016, indicando o custo da APC. Na primeira parte da pesquisa utilizou-se questionário on-line para 29 agências de fomento brasileiras e, complementou-se os dados referentes às políticas de fomento analisando os seus sites. Verificou-se que o financiamento da APC é praticado pela minoria das agências brasileiras. Na segunda parte coletou-se, na Web of Science Core Collection, a produção científica brasileira publicada em Acesso Aberto e agregou-se dados, formando um banco de 63.847 documentos publicados em 930 revistas. A maior parte dos documentos (69%) foi veiculada em revistas nacionais. As áreas com maior concentração de documentos foram Ciências Biológicas, da Saúde e Agrícolas. Identificou-se 610 revistas com APC responsáveis pela publicação de 37.847 documentos, apresentado um custo médio de USD1,492.27 por artigo e USD957.75 para o período de cinco anos. O valor total estimado para o período foi de aproximadamente USD36 milhões. Desse total, as revistas do programa SciELO representam 22% dos gastos, enquanto os mega-journals representam 27%. Considera-se que o Brasil possui uma política de financiamento da APC embrionária, enquanto que o número de documentos publicados em revistas de AA com APC tem um aumento mais veloz que naquelas sem a cobrança de taxa.The Article Processing Charge (APC) is an Open Access (AA) and hybrid journals publishing model. This study followed an exploratory and quantitative approach and analyzed the implications of the publication of scientific papers in AA journals paid with APC for the official scientific publication policies in Brazil. The specific objectives are: to find out the types of grants offered by the Brazilian official institutions for the publication of articles by APC; to characterize the Brazilian scientific production in AA published in 2012-2016, indicating the cost of the APC. For the first part of the study, 29 Brazilian granting agencies were asked to answer an online questionnaire on granting policies and also their websites were looked through for data collection on the subject and cross checking answers. It was found that only a minority of Brazilian granting agencies have allowances for APC. In the second part of the study, data from the Brazilian scientific papers indexed by the Web of Science Core Collection that were published in AA were put together in a database of 63,847 documents published in 930 journals. Most of the documents (69%) were published in Brazilian journals. The fields with the biggest share of documents published in AA were Biology, Health and Agricultural Sciences. We found out that 610 journals with APC published 37,847 papers, at an average cost of USD1,492.27 per paper and USD957.75 for the five year period. The estimated total value for the period was approximately USD36 million. Of this total, SciELO program journals represent 22% of expenditures and mega journals represent 27%. Brazil is beginning to develop granting policies for APC, as the number of papers published in AA journals with APC increases faster than the number of papers published without fee

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
