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
Migração intermunicipal de estudantes do ensino básico do Brasil entre 2007 e 2015
No full textDespite the dearth of studies on the subject, researchers point out the importance of considering the school trajectories of Brazilian students, both in terms of the transitions between years of study and the migratory flows. Thus, the main objective of this paper is to analyze the intermunicipal migratory flows of upper secondary students in Brazil, between the years 2007 and 2015, from a longitudinal database of the school censuses, elaborated by INEP. For periods 2007-2008, 2010-2011 and 2014-2015, the flows of the intermunicipal migrant students were selected between the 9th grade of lower secondary and the 1st year of the upper secondary; Between the 1st year School and the 2nd year of the upper secondary; And between the 2nd year and the 3rd year of the upper secondary. On average, just over 420,000 students migrated each year, between 2007 and 2015, in the periods and grades considered (around 5.0% of the total students). Migratory patterns differ: Promoted migrants have a greater diversity of short-distance movements and a greater magnitude of long-distance flows when compared to repeating and dropout students. Also, the dropout trajectories are sometimes opposed to those of the promoted or repeating students. Our exploratory results indicated unknown aspects of the reality of the students, being a starting point for more specific analyses on the differentials of school trajectories and the difficulties faced by migrant students from all over the country.A pesar de la escasez de estudios sobre el tema, las investigaciones señalan la importancia de considerar las trayectorias escolares de los estudiantes brasileños, tanto en términos de las transiciones de años de estudio como movimientos migratorios. Por lo tanto, el objetivo principal de este artículo es analizar los flujos migratorios de los estudiantes intermunicipales de la escuela secundaria en Brasil, entre 2007 y 2015 años, de un Base de datos longitudinales del censo escolar, elaborado por el INEP. Para los períodos 2007-2008, 2010-2011 y 2014-2015, los flujos de estudiantes migrantes intermunicipales fueron seleccionados entre el noveno grado de la escuela primaria y el primer año de la escuela secundaria; entre el primer año de la escuela secundaria y el segundo año de la escuela secundaria; y entre el segundo año de la escuela secundaria y el tercer año de la escuela secundaria. En promedio, poco más de 420.000 estudiantes migravan cada año, entre 2007 y 2015, en los períodos y años de estudio considerados (alrededor del 5,0% del total de estudiantes). Los patrones migratorios difieren: los migrantes promovidos presentan mayor diversidad de desplazamientos de corta distancia y mayor número de flujos de larga distancia en comparación con los repetidores y evadidos. En cambio, las trayectorias de los evadidos, a veces, son opuestas a aquellas de los promovidos o repetentes. Nuestros resultados indicaron aspectos poco conocidos de la realidad de los estudiantes, sirviendo como punto de partida para análisis más específicos sobre los diferenciales de trayectorias escolares y las dificultades encontradas por alumnos migrantes de todo el país.Apesar da escassez de trabalhos sobre o tema, pesquisas apontam para a importância de se considerar as trajetórias escolares dos estudantes brasileiros, tanto em termos das transições entre anos de estudo como os movimentos migratórios. Assim, o objetivo principal deste artigo é analisar os fluxos migratórios intermunicipais de estudantes do ensino médio no Brasil, entre os anos de 2007 e 2015, a partir de uma base de dados longitudinais do Censo Escolar, elaborada pelo INEP. Para períodos 2007-2008, 2010-2011 e 2014-2015, foram selecionados os fluxos dos alunos migrantes intermunicipais entre o 9º ano do Ensino Fundamental e o 1º ano do Ensino Médio; entre o 1º ano do Ensino Médio e o 2º ano do Ensino Médio; e entre o 2º ano do Ensino Médio e o 3º ano do Ensino Médio.
Em média, pouco mais de 420 mil alunos migravam a cada ano, entre 2007 e 2015, nos anos escolares e períodos considerados (em torno de 5,0% do total de estudantes). Os padrões migratórios diferem: os migrantes promovidos apresentam maior diversidade de deslocamentos de curta distância e maior número de fluxos de longa distância quando comparados aos repetentes e evadidos. Em contrapartida, as trajetórias dos evadidos, por vezes, são opostas àquelas dos promovidos ou repetentes. Nossos resultados indicaram aspectos pouco conhecidos da realidade dos estudantes, servindo como ponto de partida para análises mais específicas sobre os diferenciais de trajetórias escolares e as dificuldades encontradas por alunos migrantes de todo o país.

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.
