Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
Validación de una escala sobre dominios de creatividad para futuros profesores de ciencias naturales, tecnología y matemáticas

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
Validación de una escala sobre dominios de creatividad para futuros profesores de ciencias naturales, tecnología y matemáticas
No full textIntroduction. Investigation into the factor structure of Domains of Creativity Scale has been on for sometimes now. The purpose of this study was to test the validity of the Kaufman Domains of Creativity Scale on Nigerian preservice science, technology, and mathematics teachers.Method. Exploratory and confirmatory factor analyses were performed on the responses of 337 preservice science, technology, and mathematics teachers to the Kaufman Domains of Creativity Scale.Results. Results of both analyses supported the five-factor structure of the Kaufman Domains of Creativity Scale: Mechanical/Scientific, Scholarly, Performance (encompassing writing and music), Self/Everyday, and Artistic. Construct validity of the Kaufman Domains of Creativity Scale was supported by its relationships with the Big Five Inventory in ways that were predicted by theory and consistent with previous research. Coefficient alphas and coefficients of congruence were generally strong.Discussion and Conclusion. The present study provided incremental validity to the multidimensional nature of the Kaufman Domains of Creativity Scale thus reinforcing the five-factor model namely Mechanical/Scientific, Scholarly, Performance (encompassing writing and music), Self/Everyday, and Artistic. Additionally, a Nigerian version of the 50-item Kaufman Domains of Creativity Scale in the three major indigenous languages: Hausa, Igbo, and Yoruba need to created and tested among undergraduate and postgraduate students in Nigerian institutions of higher learning.Introducción. La investigación sobre la estructura factorial de la Escala de Dominios de la Creatividad ha sido abundante hasta ahora . El propósito de este estudio fue probar la validez de las Esclas Kaufman de la Creatividad en una muestra de estudiantes de ciencia y tecnología, y matemáticas de pregrado nigeriana .Método. Análisis factoriales exploratorios y confirmatorios se realizaron en las respuestas de los profesores de matemáticas de 337 alumnos de pregrado de ciencia y tecnología. Que contestaron a los dominios de la Escla Kaufman de Creatividad .Resultados. Los resultados de ambos análisis apoyaron la estructura de cinco factores de los Dominios Kaufman de la Escla de Creatividad Escala: académica, de rendimiento (que abarca la escritura y la música) mecánica/científico, auto-percepción y Artístico. La validez de constructo de los dominios de la Escala Kaufman recibió el apoyo de sus relaciones con el inventario de los cinco grandes en formas que fueron predichas por la teoría y consistentes con investigaciones previas. Los coeficientes Alfa y de congruencia fueron generalmente altos.Discusión y conclusión. El presente estudio proporciona validez incremental a la naturaleza multidimensional a la Escala de Dominios de la Creatividad Kaufman, reforzando así el modelo de cinco factores, académica, de rendimiento (que abarca la escritura y la música), a saber Mecánico / Científico, Auto-percepción y Artístico. Además, una versión nigeriana de la Escala de 50-item Kaufman de Dominios, en los tres principales idiomas indígenas (Hausa, Igbo, y Yoruba) es necesario crear y probar entre los estudiantes de pregrado y posgrado en las instituciones de educación superior de Nigeria
