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
Entre deux: Contribución a su construcción teórica desde las múltiples escalas del territorio
Get PDFThe "Entre-deux" is defined by Ecrement Bernard as an "interval" of "new multicultural otherness, peaceful and open" at the intersection of territorialities". This work is progressing in its theoretical construction: redefines it as distance-time interface with sufficiently stable environment and space components (topology, morphology, typology, symbolism) for cultural diversity is built and developed. He bases his research through anthropological structures and the phenomenology of
space and geopolitics. Intends to work on: the city as laboratory-Entre-deux machine, a typology of cities referred to multicultural otherness, a mapping of the Entre-deux opportunities. Exemplifies the contribution of land use with a borderline case: Rivera (Uruguay-Brazil).El "Entre-deux" es definido por Bernard Ecrement como un "intervalo" de "alteridad multicultural nueva, pacífica y abierta" en el cruce de territorialidades. El presente trabajo avanza en su construcción teórica: lo redefine como interfase de distanciatiempo con estabilidad ambiental y de los componentes espaciales (topología, morfología, tipología, simbolismo) suficiente para que la pluralidad cultural se construya y desarrolle. Fundamenta su investigación mediante las estructuras antropológicas y la fenomenología del espacio y la geopolítica. Propone trabajar sobre: la ciudad como máquina-laboratorio del Entre-deux, una tipología de ciudades referida a la alteridad multicultural, una
cartografía de oportunidades del Entre-deux. Ejemplifica el aporte del ordenamiento territorial con un caso fronterizo: Rivera (Uruguay- Brasil)
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
Manejo de bordes de crecimiento urbano en Uruguay
No full textConfrontado a los procesos universales de crecimiento urbano, la pregunta-desafío para el urbanista no debería ser si la expansión ocurrirá sino cómo conducirla, domesticarla, darle forma, calidad, estructura y timing.Con la transformación de la ciudad grande en área metropolitana, el concepto de borde urbano-rural y sus problemáticas se complejizó. Territorios de intersticios periurbanos necesitan de su propia reflexión y generación de prácticas urbanísticas, aplicando herramientas innovadoras para integrar, completar y diseñar con calidad los "parches", bordes, islas y vacíos del tejido urbano heredado, y organizar nuevas expansiones caracterizadas por modalidades insospechadas de hibridación de territorios escasamente regulados.Sobre la base de las singularidades del caso uruguayo, el artículo plantea alternativas al manejo de procesos de borde bien diferenciados: fajas de interfase urbano-rural altamente mixturadas y fragmentadas, territorios desregulados, bordes urbanizados como partes formalmente completas, periferias que necesitan fortalecer su gobernanza y periurbanos ramificados.En el sistema de ordenamiento territorial y desarrollo sostenible se encuentran las herramientas para lidiar con conflictos y paradojas: planes parciales, programas de actuación integrada, estrategias para la complejidad y la incertidumbre, la aplicación obstinada de los principios legales y doctrinales en procura de la calidad, el manejo combinado de instrumentos y de escalas..
