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
Políticas públicas y convergencia infocomunicacional en Uruguay: regulaciones e institucionalidad en los gobiernos del Frente Amplio en Uruguay (2005-2014)
Get PDFEn esta investigación se analizan los dos primeros gobiernos del Frente Amplio en Uruguay, entre los años 2005-2010 y 2010-2014, en relación con las políticas públicas en materia de Servicios de Comunicación Audiovisual (sca) y telecomunicaciones.
Uruguay como país no ha estado exento de cambios tecnológicos en el campo de los sca y las telecomunicaciones. En ese sentido, consignamos que ha procesado la transición a la televisión digital y ha impulsado una agresiva política de conectividad a través del tendido de fibra óptica al hogar por parte de su empresa pública de telecomunicaciones, antel.
En el período comprendido por esta investigación se llevó adelante una nutrida agenda de cambios regulatorios en materia de sca, al momento de mantener casi intocada su estructura regulatoria en materia de telecomunicaciones.
A pesar de estos cambios regulatorios y de la irrupción de nuevas posibilidades tecnológicas, la estructura de mercados y servicios en el campo de los sca y las telecomunicaciones no ha variado sustancialmente, manteniéndose un mercado concentrado en el negocio de la televisión comercial abierta y por abonados, mientras que en el campo de las telecomunicaciones se mantienen tres operadores en régimen de competencia en el mercado de la telefonía móvil y un cuasi monopolio en la conectividad por fibra óptica por parte de la empresa estatal antel.
Esta investigación da cuenta que esta transición tecnológica se procesó a caballo de los dos gobiernos iniciales de la coalición de izquierda Frente Amplio (2005-2010; 2010-2015) e instaló en la agenda pública la discusión sobre la conveniencia de una nueva regulación que asegurase una mejor administración de los recursos en el marco de las denominadas tecnologías convergentes.
La productividad legislativa y regulatoria en relación con los sca en Uruguay tuvo sus hitos principales en la aprobación de la ley de Radiodifusión Comunitaria en el primer período de gobierno y la ley de Servicios de Comunicación Audiovisual en el segundo. En el caso de las telecomunicaciones, en cambio, no hubo casi ninguna modificación sustancial en materia regulatoria y de gestión.
El proceso de discusión y aprobación de este nuevo marco regulatorio mostró algunas particularidades del caso uruguayo, pautado por un mercado acotado y partido entre los sca y las telecomunicaciones. En el campo de los sca se ha ido incrementando la regulación —aunque con rezagos importantes de aplicación— pero esto no ha afectado el dominio del mercado por parte de tres grupos empresariales nacionales, a los que se suman el Grupo Clarín de Argentina y la norteamericana Direct TV.
El desarrollo de una doble escena en Uruguay evidencia la presencia de distintas agendas políticas para encarar los imprescindibles procesos de reforma en un entorno de convergencia.Doctor en ComunicaciónUniversidad Nacional de La PlataFacultad de Periodismo y Comunicación Socia
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
