    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

    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

Centro de Investigación de Riesgos y Sostenibilidad en la Construcción de Aveiro; Portugal.Gran parte de la estructura de hormigón armado se han construido en la primera mitad del Siglo XX,porloque su vida útil se encuentra actualmente en una etapa crítica desde la perspectiva del mantenimiento.Uno de los mecanismos de degradación más frecuentes y costosos en este tipo de infraestructura está asociado con la corrosión del refuerzo inducida por el fenómeno de carbonatación. Bajo este contexto,el objetivo de este artículo fue la formulación de un modelo de toma de decisiones para la planificación de la inspección óptima. Los tiempos de inspección fueron optimizados considerando la incertidumbre inherente al proceso de degradación y una compensación entre los costos de inspección y la capacidad de servicio de la estructura. Se ha elaborado un análisis de eficiencia través de dos enfoques: el Análisis de Frontera Estocástica y el Análisis de envolvente multidireccional. Este análisis proporciona una evaluación que reduce el número de técnicas de inspección necesarias y el intervalo de tiempo entre inspecciones para proporcionarnos una solución óptima, sino también más eficiente. Así, el resultado de esta investigación comprende un modelo numérico para la obtención de los tiempos de inspección más adecuados durante la vida útil de la estructura.Much of the reinforced concrete structures were built in the first half of the 20th century, so their service life is currently at a critical stage from a maintenance perspective. One of the mechanisms more frequent and costly degradation in this type of infrastructure is associated with reinforcement corrosion induced by the phenomenon of carbonation. In this context, the objective of this article was the formulation of a Decision-making model for optimal inspection planning. The inspection times were optimized considering the uncertainty inherent in the degradation process and a trade-off between the costs of inspection and serviceability of the structure. An efficiency analysis has been developed through two approaches: Stochastic Frontier Analysis and Multidirectional Envelope Analysis. This analysis provides an assessment that reduces the number of inspection techniques required and the time interval between inspections to provide not only an optimal solution, but also a more efficient one. Thus, the result of this research It comprises a numerical model to obtain the most adequate inspection times during the useful life of the structure

    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

    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
