Declaración de San Francisco sobre la evaluación de la investigación
Get PDFIntroduction and objective: There is a pressing need to improve the ways in which the output of scientific research is evaluated by funding agencies, academic institutions, and other parties. To address this issue, a group of editors and publishers of scholarly journals met during the Annual Meeting of The American Society for Cell Biology (ASCB) in San Francisco, CA, on December 16, 2012. Method: The group developed a set of recommendations, referred to as the San Francisco Declaration on Research Assessment. Results and Discussion: The Journal Impact Factor is frequently used as the primary parameter with which to compare the scientific output of individuals and institutions. The Journal Impact Factor has a number of well-documented deficiencies as a tool for research assessment: citation distributions within journals are highly skewed; the properties of the Journal Impact Factor are field-specific: it is a composite of multiple, highly diverse article types, including primary research papers and reviews; Journal Impact Factors can be manipulated by editorial policy and data used to calculate the Journal Impact Factors are neither transparent nor openly available to the public. Our recommendations focus primarily on practices relating to research articles published in peer-reviewed journals but can and should be extended by recognizing additional products, such as datasets, as important research outputs. These recommendations are aimed at funding agencies, academic institutions, journals, organizations that supply metrics, and individual researchers. Conclusions: A number of themes run through these recommendations: the need to eliminate the use of journal-based metrics, such as Journal Impact Factors, in funding, appointment, and promotion considerations; the need to assess research on its own merits rather than on the basis of the journal in which the research is published; and the need to capitalize on the opportunities provided by online publication (such as relaxing unnecessary limits on the number of words, figures, and references in articles, and exploring new indicators of significance and impact).Introducción y objetivo: Existe una necesidad apremiante de mejorar las formas en que los organismos de financiación, las instituciones académicas y otras partes evalúan el resultado de la investigación científica. Para abordar este tema, un grupo de editores y editores de revistas académicas se reunió durante la reunión anual de The American Society for Cell Biology (ASCB) en San Francisco el 16 de diciembre de 2012. Método: el grupo desarrolló un conjunto de recomendaciones, conocidas como la Declaración de San Francisco sobre Evaluación de la Investigación. Resultados y Discusión: El factor de impacto (FI) de la revista se usa frecuentemente como el parámetro principal con el cual comparar la producción científica de individuos e instituciones. El FI tiene una serie de deficiencias bien documentadas como herramienta para la evaluación de la investigación: las distribuciones de citas dentro de las revistas son muy sesgadas; las propiedades del FI son específicas del campo: es un compuesto de múltiples tipos de artículos altamente diversos, que incluyen trabajos de investigación primaria y revisiones; el FI de la revista pueden ser manipulados por la política editorial y los datos utilizados para calcular los FI de la revista no son transparentes ni están a disposición del público. Nuestras recomendaciones se centran en las prácticas relacionadas con los artículos de investigación publicados en revistas revisadas por pares, pero pueden y deben ampliarse reconociendo productos adicionales, como los conjuntos de datos, o productos de investigación importantes. Estas recomendaciones están dirigidas a agencias de financiación, instituciones académicas, revistas, organizaciones que proporcionan métricas e investigadores individuales. Conclusiones: Una serie de temas se basan en estas recomendaciones: la necesidad de eliminar el uso de métricas basadas en revistas, como los FI, en consideraciones de financiación, designación y promoción; la necesidad de evaluar la investigación por sus propios méritos en lugar de basarse en la revista en la que se publica la investigación; y la necesidad de capitalizar las oportunidades que ofrece la publicación en línea (como relajar los límites innecesarios en el número de palabras, cifras y referencias en los artículos, y explorar nuevos indicadores de importancia e impacto)
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
