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
¿Álgebra en la escuela primaria uruguaya?
Get PDFEl programa para educación inicial y primaria (2008) incorpora como eje temático el álgebra por lo cual se hace imprescindible e ineludible su abordaje como objeto de estudio y como objeto de enseñanza. Importa discutir cuál es el marco en el cual se incluye el álgebra en el trabajo escolar y cuál es la concepción de matemática y en especial de álgebra que maneja la nueva propuesta programática. Interesa aportar elementos a los maestros de educación primaria que enriquezcan la lectura del texto programático e incidan positivamente en sus prácticas de enseñanza

Enseñanza de la geometría en la escuela primaria. Cómo entrelaza el maestro, en sus prácticas, la matemática, el contexto y sus alumnos
No full textThe present paper introduces the main lines articulating an investigation on the
construction methodology of teaching practices in elementary school Geometry.
The research was sustained by a positive conception of the work of elementary school teachers,
taking as hypothesis the conviction that educators reflect on their practices. Of particular interest
was to obtain data that would shed light on the particular ways each teacher constructs classroom
practices while teaching Geometry, and attempt to respond whether this construction differs
or not, depending on the object of study and the area of knowledge it belongs to. To achieve
these objectives, several interviews with four private schools in the city of Montevideo were
performed, and it was possible to classify teaching practices in Geometry into five categories:
practices of utility, problematizing practices, practices of repetition, overflight practices and
social responsibility.En este trabajo se presentan las líneas centrales que articularon una investigación acerca de la construcción metodológica de las prácticas de enseñanza de la Geometría en la escuela primaria. Esa investigación se sustentó en una concepción positiva del trabajo de los docentes del nivel primario, tomando como hipótesis la convicción de que ellos reflexionan sobre sus prácticas; interesó buscar datos que iluminaran las maneras singulares en las que esos docentes construyen las prácticas de aula en el momento de enseñar Geometría intentando responder si esa construcción difiere o no según el objeto de estudio y el área de conocimiento al cual pertenece. Para ello, a través de entrevistas en cuatro colegios privados de la ciudad de Montevideo se pudo llegar a categorizar las prácticas de enseñanza geométrica, como prácticas de materialización, de utilidad, de problematización, de reiteración, de sobrevuelo y de responsabilidad social
