    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

    This article presents a critical review of the methodological shortcomings to identify with reasonable criteria the demographic dynamics of Colombia, as a whole, and the transition levels of each of the regions and municipalities, emphasizing the current impossibility of relating considerable differences that exist between rural areas and so-called urban areas, as well as between each of them. In the same way, it questions the premises and tax policy proposals that has as their sole basis the data obtained by population censuses, and the arguments from authority that are not usually subjected to a real critical judgment, and reproduce, sometimes, fallacies that imply social injustice and the development of highly regressive policies. In the light of this, the author develops an index and an algorithm that not only satisfy the need for a methodology to establish, from an inclusive perspective, the phases and transition levels of each region or locality, but also constitute a baseline to establish typologies on urbanization and rural areas, with clear criteria on temporalities and gradualness, that allow the  planning and development of more comprehensive policies on protection, social security, and pensions.Este artículo presenta una revisión crítica de las carencias metodológicas para identificar con criterios razonables la dinámica demográfica de Colombia, en su conjunto promedio, y los niveles de transición de cada una de las regiones y municipalidades, haciendo énfasis en la actual imposibilidad de identificar los marcados contrastes que existen entre las ruralidades y las llamadas zonas urbanas, así como entre ellas mismas. De igual forma, cuestiona las premisas y propuestas políticas impositivas que tienen como único asidero los datos arrojados por los censos poblacionales, así como argumentos de autoridad que no suelen ser sometidos a un real juicio crítico, reproduciendo, en ocasiones, falacias que traen consigo injusticia social y el desarrollo de políticas altamente regresivas. A partir de este ejercicio, el autor desarrolla un índice y un algoritmo que no solo satisfacen la necesidad de contar con una metodología para establecer, con enfoque diferencial, las fases y niveles de transición de cada región o localidad, sino que además constituyen un punto de partida para establecer tipologías sobre urbanización y ruralidades, con claros criterios sobre temporalidades y gradualidades, que permitan la planeación y el desarrollo de políticas integrales y articuladas sobre protección, seguridad social y pensiones

    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
