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
Determinantes de las exportaciones bajo el enfoque de las elasticidades del comercio: evidencia empírica para Argentina, Brasil y Paraguay
Full text linkEl objetivo de este trabajo consiste en estudiar los determinantes de las exportaciones de Argentina, Brasil y Paraguay bajo el enfoque de las elasticidades de comercio.
Los resultados destacan, por un lado, la baja elasticidad que tienen los volúmenes de comercio al tipo de cambio real multilateral en relación a la respuesta a los cambios en el PIB de sus principales socios comerciales. Por el otro, el efecto negativo que genera la volatilidad cambiaria.The purpose of this study is to analyze and provide evidence about the determinants of exports from Argentina, Brazil and Paraguay with the trade elasticities approach.
Export´s elasticity to multilateral real exchange rate is lower in relation to the response to changes in output of the major trading partners. On the other hand, high volatility of exchange rate generates a negative effect.Facultad de Ciencias Económica
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
Incidencia tributaria en Argentina
Full text linkEste estudio examina la incidencia distributiva de algunos de los principales impuestos nacionales que componen el sistema impositivo argentino. Para ello se utiliza la Encuesta Nacional de Gastos de los Hogares 2004-2005. Los impuestos aquí analizados son el impuesto al valor agregado (IVA), los impuestos al trabajo (denominados aportes y contribuciones a la seguridad social), algunos impuestos especí cos (denominados impuestos internos) a bienes y servicios (cigarrillos, bebidas alcohólicas y no alcohólicas, seguros y telefonía celular) y el impuesto a las ganancias de personas físicas. Esto representa un primer paso hacia un estudio de incidencia impositiva que abarque todo el sistema impositivo argentino. Utilizando como indicadores de bienestar el ingreso per cápita familiar (ipcf) y el consumo per cápita familiar aproximado por el gasto de las familias (gpcf), los resultados indican que el IVA resulta regresivo utilizando un enfoque tradicional de incidencia corriente (ipcf), mientras que se vuelve proporcional al utilizar un enfoque intertemporal (gpcf). El impuesto al trabajo es prácticamente proporcional en el caso del ipcf, pero claramente regresivo al considerar el gpcf como variable de bienestar. El impuesto a las ganancias de personas físicas es altamente progresivo de acuerdo a ambos indicadores de bienestar y los impuestos internos analizados son en su mayoría regresivos independientemente del indicador de bienestar utilizado, con excepción del impuesto a los seguros que es marcadamente progresivo.Facultad de Ciencias Económica
