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

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
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
O uso de “imaginar”, “supor” e “pensar” como expressão de comparação no Português do Brasil
Full text linkThe aim of this study is to investigate the syntactic, semantic, and discursive behavior of "propositional attitude imperative constructions (CIAP)." We start with two hypotheses: 1) comparison is not merely a semantic category but results from a broader cognitive scheme; 2) statements introduced by epistemic verbs like “pensar” (think), “imaginar” (imagine), and “supor” (suppose) can function as discourse markers and mediate circumstantial relations of comparison when integrated with the subordinating conjunction "que." The central justification lies in the gap in normative grammars in describing the expression of comparison in Brazilian Portuguese (BP), especially at the discursive level. Methodologically, the study is based on Cognitive Linguistics and Usage-Based Construction Grammar (UBCG), using Corpus Linguistics strategies to analyze 1,000 samples selected from 9,679 occurrences in Corpus do Português. Additionally, a psycholinguistic task was conducted to measure language users\u27 perception of comparison. The results indicated that propositional attitude imperative constructions predominantly occur in exemplification contexts, similar to canonical comparisons, with a high perception of comparability. A preference for using the verbs “imaginar” and “supor” in hypothetical comparisons was also observed.O objetivo deste estudo é investigar o comportamento sintático, semântico e discursivo das Construções Imperativas de Atitude Proposicional (CIAP). Partimos de duas hipóteses: 1) a comparação não é apenas uma categoria semântica, mas resulta de um esquema cognitivo mais amplo; 2) enunciados introduzidos por verbos epistêmicos – “pensar”, “imaginar”, “supor” – podem, se integrados à conjunção subordinativa "que", funcionar como marcadores discursivos e mediar relações circunstanciais de comparação. A justificativa central reside na lacuna das gramáticas normativas em descrever a expressão de comparação no PB, especialmente no nível discursivo. Metodologicamente, o estudo se baseia na Linguística Cognitiva e na Gramática de Construções Baseada no Uso (GCBU), utilizando estratégias da Linguística de Corpus para analisar 1000 amostras selecionadas entre 9679 ocorrências do Corpus do Português. Além disso, foi realizada uma tarefa psicolinguística para medir a percepção da comparação pelos usuários da língua. Os resultados indicaram que as CIAP ocorrem predominantemente em contextos de exemplificação, similares às comparações canônicas, com alta percepção de comparabilidade. Também foi observada a preferência pelo uso dos verbos “imaginar” e “supor” em comparações hipotéticas.
As fundamentações deste estudo recorrem à Linguística Cognitiva e à Gramática de Construções Baseada no Uso (GCBU). Mais especificamente, consideram-se aqui as contribuições de Langacker (1987, 2008), Johnson (1987) e Hilpert (2014), no sentido de delinear as dimensões estruturais, discursivas e cognitivas da referida construção. Tais perspectivas teóricas alicerçaram nossas escolhas metodológicas, principalmente no que se refere à convencionalidade e à frequência dos usos linguísticos. Inicialmente, aplicamos estratégias comuns à Linguística de Corpus, a fim de alçar dados reais e suficientemente representativos. Foram extraídas, pela plataforma Corpus do Português, 9679 ocorrências, dentre as quais 1000 amostras foram selecionadas para análise. Numa segunda etapa, desenvolvemos uma tarefa psicolinguística de compreensão, cujos itens do experimento foram elaborados a partir dos resultados da análise do corpus. O objetivo foi medir estatisticamente, em uma amostra de usuários da língua, o quanto a comparação pode ser percebida quando há este tipo de construções imperativas. Com o experimento, os usuários também puderam indicar se consideravam essas estruturas necessárias (ou não) para identificar a comparabilidade na relação entre as orações e frases. Ao serem cruzados os resultados das análises, chamou atenção a quase totalidade de construções em contextos de exemplificação (frames de exemplo), comuns também a construções comparativas canônicas. Foram esses também os itens que apresentaram índices mais altos de comparabilidade na tarefa de compreensão, se correlacionados com as outras realizações da mesma construção. As análises também indicaram predileção entre o uso dos verbos, de modo que “imaginar” e “supor” sejam os preferidos ao se estabelecerem comparações hipotéticas.
