Diseño y elaboración de un objeto virtual de aprendizaje para el conocimiento del mentol, un terpeno presente en la yerbabuena, y sus aplicaciones a la vida diaria
Get PDFLa finalidad de la enseñanza de las ciencias naturales en la escuela es el desarrollo de habilidades de pensamiento científico, que aproximen al estudiante a la comprensión de fenómenos naturales, por ello es importante hacer una aproximación conceptual. En este trabajo se diseña un Objeto Virtual de Aprendizaje OVA, que expone sistemáticamente la relación que existe entre los conceptos: planta medicinal aromática, compuesto químico orgánico mentol y metabolito secundario y sus múltiples aplicaciones en la vida diaria, contribuyendo de esta manera a facilitar en el estudiante de básica secundaria el establecimiento del mayor número de relaciones conceptuales; teniendo en cuenta que en el Colegio INEM Francisco de Paula Santander, existe la huerta escolar y un cultivo de plantas aromáticas medicinales, se utilizará este contexto para generar el interés hacia la importancia de las ciencias naturales en la sociedad. / Abstract: Abstract: The purpose of natural science education in school is to develop scientific thinking skills in other to the student get closer to understanding natural phenomena, so it is important to make a conceptual approach. This paper designs a Virtual Learning Object OVA, which exposes systematically the relationship between the concepts of aromatic herb, organic chemical compound menthol and secondary metabolite and its many applications in everyday life, thus helping to facilitate basic secondary student the establishment of more conceptual relations, taking into account that in the College INEM Francisco de Paula Santander, there is a school garden and growing medicinal herbs, this context is used to generate interest in the importance natural science in society.Maestrí
Formando lideres y transformando el ambiente.La construcción del pensamiento ambiental en la escuela una opción para vivir mejor. [Documento Electrónico].
No full textEsta obra está estructurada en tres capítulos: Contextualización institucional, Formando líderes y transformando el ambiente, y finalmente, Construcción de pensamiento ambiental. A través de ellos se hace una descripción de los procesos que impactan lo cognitivo, lo praxiológico y lo ético de los integrantes de la comunidad Barayista. Su lectura es amena, en él se narra una experiencia teniendo en cuenta el ámbito escolar, la concepción de lo ambiental desde la teoría de sistemas y subsistemas, así como la de los entornos: a saber, el natural que promueve la participación y la promoción de la ética ambiental; el escolar concebido como un conjunto de intersubjetividades producto de factores externos (ej. la cultura familiar de docentes-estudiantes, sus condiciones socio-económicas, la ética individual y colectiva en la transformación del contexto, etc.); y por último, el entorno socio-cultural que hace referencia a las interacciones de los integrantes de la comunidad educativa, las formas de ser y de actuar, de cada miembro aportando a la construcción de la cultura escola
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
