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
Circular Economy Mainstream: an Analysis of Master Thesis and Dissertations
Get PDFThe specialized scientific production resulting from master\u27s and doctoral research works and reports, indicates existing targets and advances in specialized research in circular economics. This study aims to develop a systematic literature review that highlights the thematic axes and areas of interest in the field of circular economics that are addressed in highly specialized studies, the result of master\u27s and doctoral studies. 11 predominant areas of interest of researchers in theses and dissertations are identified, denominated as categories, and other 5 smaller areas, denominated study subcategories. A framework is proposed that organizes the various identified themes and provides a holistic understanding of the insertion of the circular economy in the master\u27s and doctoral programs. The study contributes to the theory by mapping, describing and organizing in a logical way the thematic paths and axes that the theses and dissertations take when describing and addressing different associated research problems. From a practical point of view, this study can assist decision makers and policy makers in raising awareness and knowledge about possible fields of action regarding its implementation
Validation of the Measurement Scale for the Circular Economy: a proposal based on the precepts of innovation
No full textObjective: This article is a research report that is part of a study that aims to build a measuring scale for circular economy business models based on the precepts of innovation and validation of the structural model. The report presented consists of the pre-validation of the research instrument, adopted as the stage of development and validation of the final scale of the research.
Method: The validation of the research instrument is part of the procedures adopted for refining and enabling the presentation of the final scale. The theoretical research analysis model consists of four constructs (Innovation, Resource Recovery, Circular Economy Business Models and Value Proposition), for which four questionnaires were created with a pool of 149 initial items.
Originality/Relevance: The relevance for carrying out the study is associated with the need to expand knowledge about the field of circular economy, based on valid and reliable metrics. The initiatives advance towards measuring circular economy indicators. However, the issue of constructing measurement scales remains obscure and subject to different concepts, which do not always converge. Therefore, this study bears a conceptual, theoretical and scientific advance in this field, by proposing the construction of a wide measuring scale in circular economy.
Results: The scale was applied to companies in the service sector. The questionnaire items were generated from systematic literature reviews focusing on circular economy, innovation and sustainability. 149 initial scale items were generated, distributed among the dimensions Business Models of Circular Economy, Resource Recovery, Innovation and Value Proposition. From the exploratory factor analysis, 48 scale items that did not present satisfactory factor loading were excluded. The questionnaires were applied to a total sample of 223 respondents, distributed into four groups.
Theoretical/methodological contributions: This article contributes to the field of circular economy and innovation by proposing the construction and validation of a measuring scale for circular economy and innovation. In a search performed in the Scopus, Web of Science, ScienceDirect, Emerald, Google Scholar, Wiley Online Library, Sage, Springer, Taylor and Francis and JSTOR databases, the existence of studies on the validation of scales in circular economy was revealed. The development of academic works in gray literature, including national and international dissertations and theses, with searches operated in the Google Scholar databases and in the Brazilian Digital Library of Theses and Dissertations, also did not allow us to identify works with the configuration of scale validation in circular economy in the broad sense.Objetivo: O presente artigo é um relatório de pesquisa que faz parte de estudo que tem por objetivo a construção de escala de mensuração de modelos de negócios de economia circular pautada nos preceitos da inovação e validação do modelo estrutural. O relatório apresentado consiste na pré-validação do instrumento de pesquisa, adotado como estágio de desenvolvimento e validação da escala final da pesquisa.
Método: A validação do instrumento de pesquisa faz parte dos procedimentos adotados para refinamento e viabilização da apresentação da escala final, conforme proposto pelo protocolo de Costa (2011), adotado como norteador metodológico. O modelo teórico de análise da pesquisa consiste em quatro constructos (Inovação, Recuperação de Recursos, Modelos de Negócios de Economia Circular e Proposição de Valor), para os quais criaram-se quatro questionários com um pool de 149 itens iniciais.
Originalidade/Relevância: A pertinência para realização do estudo, está associada a necessidade de expansão do conhecimento sobre o campo da economia circular, a partir de métricas válidas e confiáveis. As iniciativas avançam rumo à mensuração de indicadores de economia circular (Corona et al., 2019; Reid & Rout, 2020), contudo, o tema da construção de escalas de mensuração permanece obscuro e sujeito a diferentes conceituações, nem sempre convergentes. Portanto, este estudo comporta justificativa conceitual, teórica e avanço científico neste campo, ao propor a construção de uma escala de mensuração ampla em economia circular. Em busca executada nas bases Scopus, Web of Science, ScienceDirect, Emerald, Google Scholar, Wiley Online Library, Sage, Springer, Taylor and Francis e JSTOR, revelou-se a existência de estudos sobre validação de escalas em economia circular. O desenvolvimento de trabalhos acadêmicos de literatura cinzenta, incluindo dissertações e teses nacionais e internacionais, com buscas operadas nas bases Google Scholar e na Biblioteca Digital Brasileira de Teses e Dissertações, também não nos permitiu identificar trabalhos com a configuração de validação de escala em economia circular no sentido amplo.
Resultados: A escala foi aplicada em empresas do setor de serviços. Os itens do questionário foram gerados a partir de revisões sistemáticas de literatura com foco em economia circular, inovação e sustentabilidade. Foram gerados 149 itens de escala iniciais, distribuídos entre as dimensões Modelos de Negócios de Economia Circular, Recuperação de Recursos, Inovação e Proposição de Valor. Da análise fatorial exploratória, foram excluídos 48 itens de escala que não apresentaram carga fatorial satisfatória. Os questionários foram aplicados a uma amostra total de 223 respondentes, distribuídos em quatro grupos.

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
