¿Autorregulación?... y más: la protección y defensa de los derechos de la infancia en Internet
Get PDFEste estudio es el resultado del trabajo realizado a iniciativa de UNICEF-Comité Español, a través del Instituto Universitario Mixto Universidad Autónoma de Madrid-UNICEF de Necesidades y Derechos de la Infancia y la Adolescencia (IUNDIA) y con la colaboración de un equipo de investigadoras e investigadores de la Universidad Carlos III de Madrid, expertos en medios de comunicación, infancia y educación.El objetivo de esta investigación es detectar y analizar los riesgos potenciales a los que nuestros niños, niñas y adolescentes se ven expuestos cuando navegan por Internet, así como promover la responsabilidad de los distintos actores implicados, en especial de las empresas proveedoras de servicios y contenidos.Financiado por el Ministerio de Trabajo y Asuntos Sociale
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
Estudio de errores refractivos experiencia y análisis de errores refractivos encontrados en pacientes de la Fundación Vista para Todos, sede Ibarra
Get PDFRefractive errors are those which are characterized by low quality vision. Depending on the author, refractive errors can be classified into 3 or 4 different types. That purpose of this study is to determine the prevalence of refractive errors in the city of Ibarra, in order to serve as a reminder to all optometrists that one of our main functions is the prevention and primary care of visual health.Los errores refractivos son aquellos que se caracterizan por poseer una mala calidad visual. Dentro de los errores refractivos se pueden identificar 3 o 4 tipos dependiendo del autor que los clasifica. El propósito de este estudio es determinar la prevalencia de errores refractivos en la ciudad de Ibarra, para que sirva como recordatorio a todos los optómetras que unas de nuestras principales funciones son la prevención y atención primaria de la salud visual
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
