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
Enfoques geolingüísticos para la descripción de variedades del portugués brasileño: aspectos de contacto, migracionales y histórico-sociales
No full textThis paper proposes a theoretical and methodological review of Brazilian Geolinguistics, presenting three emerging lines of approach: contactual, migrational, and historical-social. Grounded in Pluridimensional and Relational Dialectology (Radtke; Thun, 1996), the study assumes that social and historical dimensions are inseparable from linguistic variation, requiring the understanding of language within its contexts of mobility, contact, and sociocultural formation. The contactual approach is analyzed as the axis that redefines traditional Geolinguistics by incorporating the study of languages in contact and the mutual influence among linguistic varieties. In southern Brazil, projects such as the Atlas Linguístico-Etnográfico da Região Sul (ALERS) and the Atlas Linguístico-Contatual das Minorias Alemãs na Bacia do Prata (ALMA-H) stand out, both aimed at describing Portuguese in contact with immigration languages. In the North, studies by Sanches (2020), Guedes (2017), and Rodrigues (2017) highlight the interinfluence between Portuguese and indigenous languages, as well as processes of linguistic replacement and hybridization. The migrational approach broadens the analytical perspective by including the diatopic-kinetic dimension, which compares the linguistic behavior of stable and mobile groups (topostatic and topodynamic). Research conducted by Figueiredo (2014), Cuba (2015), Silva (2018), and Meurer (2022) demonstrates how population mobility and urban-rural continuums influence phonetic-phonological and lexical phenomena. The process of covariation, understood as the coexistence of regional and supraregional variants, is interpreted as a reflection of migrational dynamics and the complex sociolinguistic fabric of Brazil. Finally, the historical-social approach focuses on historical-linguistic routes. In this line, the Atlas Linguístico da Rota dos Tropeiros (Chofard, 2023) exemplifies how historical paths and events can define dialectal areas and explain intervarietal contacts between the São Paulo and Rio Grande do Sul varieties. It is concluded that these three approaches do not compete but rather complement each other, consolidating Brazilian Geolinguistics as a pluridimensional science open to new analytical perspectives.Este trabajo propone una revisión teórico-metodológica de la Geolingüística brasileña, presentando tres líneas de enfoque emergentes: la de contacto, la migracional y la histórico-social. Fundamentado en la Dialectología Pluridimensional y Relacional (Radtke & Thun, 1996), el estudio parte del supuesto de que las dimensiones sociales e históricas son inseparables de la variación lingüística, siendo necesario comprender la lengua en sus contextos de movilidad, contacto y formación sociocultural. El enfoque de contacto se analiza como el eje que redefine la Geolingüística tradicional al incorporar el estudio de las lenguas en contacto y la influencia mutua entre variedades lingüísticas. En el sur de Brasil, se destacan proyectos como el Atlas Linguístico-Etnográfico da Região Sul (ALERS) y el Atlas Linguístico-Contatual das Minorias Alemãs na Bacia do Prata (ALMA-H), orientados a la descripción del portugués en contacto con lenguas de inmigración. En el norte, estudios como los de Sanches (2020), Guedes (2017) y Rodrigues (2017) evidencian la interinfluencia entre el portugués y las lenguas autóctonas, además de procesos de sustitución e hibridación lingüística. El enfoque migracional amplía la perspectiva analítica al incluir la dimensión diatópico-kinética, que compara el comportamiento lingüístico de grupos estables y móviles (topostáticos y topodinámicos). Investigaciones desarrolladas por Figueiredo (2014), Cuba (2015), Silva (2018) y Meurer (2022) demuestran cómo la movilidad poblacional y los continuos urbano-rurales influyen en fenómenos fonético-fonológicos y léxicos. El proceso de covariación, entendido como la coexistencia de variantes regionales y suprarregionales, se interpreta como un reflejo de las dinámicas migracionales y del complejo entramado sociolingüístico brasileño. Finalmente, el enfoque histórico-social se centra en las rutas histórico-lingüísticas. En esta vertiente, el Atlas Linguístico da Rota dos Tropeiros (Chofard, 2023) ejemplifica cómo los recorridos y eventos históricos pueden delimitar áreas dialectales y explicar contactos intervarietales entre las variedades paulista y sur-rio-grandense. Se concluye que estos tres enfoques no compiten, sino que se complementan, consolidando la Geolingüística brasileña como una ciencia pluridimensional y abierta a nuevas perspectivas de análisis.Este trabalho propõe uma revisão teórico-metodológica da Geolinguística brasileira, apresentando três frentes de abordagens emergentes: a contatual, a migracional e a histórico-social. Fundamentado na Dialetologia Pluridimensional e Relacional (Radtke; Thun, 1996), o estudo parte do pressuposto de que as dimensões sociais e históricas são indissociáveis da variação linguística, sendo necessário compreender a língua em seus contextos de mobilidade, contato e formação sociocultural. A abordagem contatual é analisada como o eixo que redefine a Geolinguística tradicional ao incorporar o estudo das línguas em contato e da influência mútua entre variedades linguísticas. No Sul do Brasil, destacam-se projetos como o Atlas Linguístico-Etnográfico da Região Sul (ALERS) e o Atlas Linguístico-Contatual das Minorias Alemãs na Bacia do Prata (ALMA-H), voltados à descrição do português em contato com línguas de imigração.

O processo de covariação, entendido como a coexistência de variantes regionais e suprarregionais, é interpretado como reflexo das dinâmicas migracionais e da complexa tessitura sociolinguística brasileira. Por fim, a abordagem histórico-social está centrada nas rotas histórico-linguísticas. Nessa vertente, o Atlas Linguístico da Rota dos Tropeiros (Chofard, 2023) exemplifica como percursos e eventos históricos podem delimitar áreas dialetais e explicar contatos intervarietais entre as variedades paulista e sul-rio-grandense.

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
