    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 link
    We 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

    We 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

    Avaliação dos benefícios do cannabidiol como tratamento adjunto em indivíduos portadores de epilepsia refratária à terapia medicamentosa padrão e cirúrgica

    OBJECTIVE: To assess whether the use of CBD­based drugs leads to better control of epileptic seizures in patients with difficult­to­control epilepsy. METHOD: this is a clinical cohort study, based on the analysis of 34 medical records for the selection of patients undergoing treatment for epilepsy who are refractory to standard antiepileptic therapy and vagal nerve stimulation (VNS) therapy and who are using derivatives cannabinoids, being followed up at the Ophir Loyola Hospital and the Institute of Functional Neurosurgery, Epilepsy and Medicinal Cannabis Dr. Francinaldo Gomes, from January 2021 to July 2022. RESULTS: Of the 34 medical records analyzed, 22 met the inclusion criteria of the study, so that, after 3 months of treatment with cannabidiol, there was a reduction in the absolute frequency of seizures from 14.43 seizures per month to 12.6, and with 6 months of treatment, reduction to 8.36, and with 9 months of treatment, reduction to 3.27 seizures per month, and finally, with 12 months of treatment, reduction to an average of 2.84 seizures per month , thus showing an average reduction of 80.31%. CONCLUSION: This analysis allowed us to reaffirm, in accordance with the international literature, the benefits of cannabidiol as an adjuvant to conventional antiepileptic therapy, and may serve as subsidiary for actions aimed at increasing access to cannabidiol­based formulations in the treatment of epilepsy.OBJETIVO: Avaliar se o uso de medicamentos à base de CBD leva a melhor controle de crises epilépticas nos pacientes com epilepsia de difícil controle. MÉTODO: trata­se de um estudo de coorte clínico, baseado na análise de 34 prontuários para seleção de pacientes submetidos a tratamento para epilepsia refratários à terapia com anticonvulsivante padrão e terapia por estimulação do nervo vago (ENV) e que estejam em uso de derivados canabinoides, em acompanhamento no Hospital Ophir Loyola e no Instituto de Neurocirurgia Funcional, Epilepsia e Cannabis Medicinal Dr. Francinaldo Gomes, no período de janeiro de 2021 a julho de 2022. RESULTADOS: Dos 34 prontuários analisados, 22 se enquadravam nos critérios de inclusão do estudo, de tal forma que, com 3 meses de tratamento com cannabidiol, ocorreu redução da frequência absoluta de crises de 14.43 crises por mês para 12.6, e com 6 meses de tratamento, redução para 8.36, e com 9 meses de tratamento, redução para 3.27 crises por mês, e finalmente com 12 meses de tratamento, redução para média de 2.84 crises por mês, constatando­se assim uma redução média de 80.31%. CONCLUSÃO: Está análise permitiu reafirmar, em concordância com a literatura internacional, os benefícios do cannabidi como adjuvante à terapia anti­epiléptica convencional, podendo servir como subsídio para ações que visem ampliar o acesso a formulaçõesa base de cannabidiol no tratamento de epilepsia

    We 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
