Riesgo de inundación en zonas urbanas y estrategias de mitigación y adaptación: Aspectos teóricometodológicos y propositivos
Full text linkEl presente capítulo desarrolla una exploración indagatoria –sin antecedentes- de tres cuestiones importantes para colaborar con la problemática de las inundaciones por lluvias extraordinarias en el Gran La Plata. Se intenta contestar: ¿Cuáles son las zonas expuestas a inundación?, ¿Qué grados de riesgo de inundación tiene la población asentada en las diferentes zonas urbanas?, ¿qué estrategias deberían gestionarse para aumentar la resiliencia de los habitantes y adaptar/ condicionar la ciudad, los barrios y las viviendas para enfrentar esa circunstancia en el mediano y largo plazo?Fil: Lopez, Isabel.

Conclusiones y reflexiones emergentes
No full textA pesar de que la inundación del 2 de abril de 2013 en la región debe considerarse como fenómeno extraordinario, con anterioridad ya hubo otros sucesos de precipitación en 24 horas que causaron grandes inundaciones. En efecto, el registro de 392,2 mm de precipitación este día, acumulado entre las 0 y las 24h, obtenido en la estación meteorológica La Plata Observatorio (LPO), “Enrique F. U. Jaschek”, de la Facultad de Ciencias Astronómicas y Geofísicas de la UNLP, es el record de su serie histórica, superando en poco más de un 400 % al valor promedio mensual para el mes de abril del período 1983 – 2012 y en más de un 225 % al record anterior en el registro histórico que comienza en 1909. Si además consideramos días consecutivos de lluvia con al menos un día de más de 100mm de su serie histórica, también se observa que esta tormenta es record, en más de un 140%.Fil: Ronco, Alicia Estela.

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

The valuation of the cultural landscape like instrument of territorial intervention
No full textEl artículo presenta una perspectiva del ordenamiento entendiendo al territorio como Paisaje Cultural, producto del binomio naturalezasociedad, y también como una estrategia de política de valoración del territorio como patrimonio, buscando y encontrando identidad.Se pone énfasis en la necesidad de un abordaje multiescalar y se presentan los principales instrumento de intervención territorial (mecanismo institucional, de gestión, técnico, de análisis e intervención).The article presents an overview of the system by understanding the territory as a cultural landscape, a product of the binomial naturesociety, and also as a political strategy of the territory as a heritage assessment, seeking and fi nding identity. It emphasizes the need for a multiscale approach and presents the main instrument of territorial intervention (institutional arrangement, management, technical, analysis and intervention).Fil: Etulain, Juan Carlos.
