Creencias de docentes chilenos de física sobre el aprendizaje de la ciencia en educación secundaria
Full text linkEsta investigación tiene como objetivo describirlas creencias de un grupo de profesores chilenos de física en relación al aprendizaje de la ciencia en el contexto de la educación secundaria de la Región de Valparaíso. Se fundamenta en la premisa de que las creencias de los docentes influyen de manera significativa en sus prácticas pedagógicas y, por ende, en la calidad de la enseñanza de las ciencias. El marco teórico establece la base conceptual para comprender la relación intrínseca entre las creencias docentes y su conducta profesional. Se hace especial hincapié en tres enfoques de creencias sobre el aprendizaje de la ciencia: apropiación formal de significados, asimilación de significados y construcción de significados. Estos enfoques ayudan a categorizar y comprender las percepciones de los docentes en cuanto a cómo los estudiantes adquieren conocimientos científicos. La metodología adoptada es cuantitativa y se basa en un diseño no experimental, transeccional, exploratorio y descriptivo. Este enfoque permite observar los fenómenos en su contexto natural y obtener una visión general de las creencias de los profesores. Se utilizó un cuestionario tipo Likert validado previamente, con proposiciones relacionadas con las diferentes creencias sobre el aprendizaje. El análisis de los datos recopilados incluyó estadística descriptiva y comparaciones por años de experiencia y género de los docentes. Los resultados reflejan una diversidad de creencias entre los profesores, destacando un fuerte consenso en la importancia del conocimiento espontáneo de los estudiantes y la aplicabilidad del aprendizaje para que adquiera significado. Se observa en los profesores de la muestra una inclinación hacia enfoques constructivistas del aprendizaje. Este estudio, proporciona una base sólida para futuras investigaciones y contribuye a la comprensión de las creencias docentes en la enseñanza de la ciencia. Esto resulta esencial para reflexionar sobre la formación docente y diseñar estrategias pedagógicas que fomenten un aprendizaje de la física más significativo en el contexto educativo chilenoThis research aims to describe the beliefs of a group of Chilean physics teachers regarding the learning of science in the context of secondary education in the Valparaíso Region. It is based on the premise that teachers' beliefs significantly influence their pedagogical practices and, therefore, the quality of science education. The theoretical framework establishes the conceptual basis to understand the intrinsic relationship between teachers' beliefs and their professional conduct. Special emphasis is placed on three approaches to beliefs about science learning: formal appropriation of meanings, assimilation of meanings, and construction of meanings. These approaches help categorize and understand teachers' perceptions of how students acquire scientific knowledge. The methodology adopted is quantitative and is based on a non-experimental, cross-sectional, exploratory, and descriptive design. This approach allows for the observation of phenomena in their natural context and provides an overview of teachers' beliefs. A previously validated Likert-type questionnaire with statements related to different beliefs about learning was used. Data analysis included descriptive statistics and comparisons by years of experience and gender of the teachers. The results reflect a diversity of beliefs among teachers, highlighting a strong consensus on the importance of students' spontaneous knowledge and the applicability of learning for it to become meaningful. The teachers in the sample show a tendency toward constructivist approaches to learning. This study provides a solid foundation for future research and contributes to the understanding of teachers' beliefs in science teaching. This is essential for reflecting on teacher education and designing pedagogical strategies that promote more meaningful physics learning in the Chilean educational context.Fil: Veron Rojas, Narciso.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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 linkWe 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 linkWe 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.
