    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

    Full text link
    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

    Validez y fiabilidad de un cuestionario sobre la percepción del profesorado de Educación Primaria y Secundaria de la enseñanza en un modelo de currículo basado en competencias

    Full text link
    The aim of this study is to develop a scale to measure primary and secondary school teachers’ perception of a competence-based curriculum model in Spain. After reviewing the literature, we designed an initial questionnaire with 37 five-point Likert-type items. This was then reviewed by a panel of experts. A pilot test was conducted with 100 participants using exploratory factor analysis. This resulted in a final scale with 23 items across five factors (beliefs about the theoretical model, level of implementation of the model, difficulties in implementing the model, resources and professional development). To verify, using new data, the level of fit of the measurement model generated by the first sample, we conducted an exploratory factor analysis, and, subsequently, a confirmatory factor analysis with structural equations on a sample of 1408 respondents. Acceptable levels of internal consistency and model fit were obtained. The result is a scale which is rapidly and easily administered. It demonstrates good criterion validity in explaining teachers’ beliefs about the competence-based curriculum model, and thus reveals teachers’ perceptions of the impact of this curricular reform.El objetivo de este trabajo es desarrollar una escala para conocer la percepción de los docentes de Educación Primaria y Secundaria del modelo de currículo basado en competencias en España. Tras revisar la literatura se diseñó un cuestionario inicial de 37 ítems tipo Likert de respuesta de cinco niveles que fue revisado por un panel de expertos. Se hizo una prueba piloto mediante un Análisis Factorial Exploratorio con 100 sujetos cuyo resultado es una escala final de cinco factores (Creencias sobre el modelo teórico, Grado de aplicación del modelo, Dificultades para la aplicación del modelo, Recursos y Formación del profesorado) de 23 ítems. Después se realizó un Análisis factorial exploratorio y, posteriormente, un Análisis factorial confirmatorio con ecuaciones estructurales a una muestra de 1.408 sujetos, para verificar con nuevos datos el grado de ajuste del modelo de medida generado con la primera muestra, obteniéndose niveles adecuados de consistencia interna y ajuste del modelo. El resultado es una escala ágil y de fácil aplicación, con buena validez de criterio explicando las creencias que el profesor tiene sobre el modelo teórico del currículo basado en competencias y, asimismo, permite conocer las percepciones del docente de las consecuencias de esta reforma curricular.This research has received funding from the Spanish Ministry of the Economy and Competitiveness.

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    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
