    Silicofitolitos : aplicaciones para la reconstrucción de los sistemas de subsistencia prehistóricos

    No full text
    En Uruguay, el análisis de silicofitolitos comienza a implementarse en la década de 1990 como una técnica alternativa para el abordaje del registro arqueobotánico, hasta entonces poco explorado dada la mala preservación de restos orgánicos. El desarrollo de las investigaciones, ha permitido trascender este carácter de "último recurso", y demostrar sus potencialidades, tanto en el marco de investigaciones arqueológicas como paleoambientales. En este trabajo se presenta, en primera instancia, una síntesis del conocimiento actual sobre los silicofitolitos, su potencial y sus limitaciones. En segundo término, se reseñan sus aportes en el marco de las investigaciones arqueológicas desarrolladas en la Cuenca de la Laguna Merín.Fil: Del Puerto, Laura.

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    Instrumentos de molienda: evidencias del procesamiento de recursos vegetales en la laguna de Castillos (Rocha, Uruguay)

    Se presentan los resultados obtenidos del estudio de instrumentos de molienda recuperados en la Excavación I del montículo A del sitio Guardia del Monte -laguna de Castillos- Uruguay. Para realizar el trabajo se procedió a la caracterización de los instrumentos de molienda mediante el relevamiento de los atributos físicos y de las características funcionales. Para esto último se aplicó la Técnica de Extracción e Identificación de Partículas Biosilíceas, con el objetivo de realizar correlaciones entre instrumentos particulares y tipos de recursos vegetales específicos. Asimismo, se emplearon fuentes escritas profundizando en los aspectos relacionados con la molienda y uso de recursos vegetales. Los resultados obtenidos permitieron identificar el procesamiento de vegetales con aplicaciones alimenticias (preparación de harinas, bebidas fermentadas, etc.) y tecnológicas (textilería, cordelería, cestería), entre los que se identificaron recursos silvestres y cultivados o manejados. Algunos instrumentos presentaron evidencias de procesamiento de recursos alimenticios, otros de recursos tecnológicos y finalmente otros con indicios de multifuncionalidad. Asimismo, se constató una cierta correlación entre algunos de los atributos físicos de los instrumentos y la funcionalidad atribuida a partir de los vegetales identificados y los usos referidos en las fuentes etnográficas.Fil: Capdepont, Irina.

Facultad de Ciencias; Uruguay.This paper presents the results from studies performed on milling stone tools recovered at Excavation I, Mound A from Guardia del Monte Site, Castillos lagoon, Uruguay. Physical attributes and functional features were used for the characterization of grinding artefacts. To this end opal phytoliths were extracted and analyzed in order to correlate different kinds of artefacts with specific vegetable resources. Written sources were used additionally to reach a deeper understanding of other aspects related to grinding activities and use of vegetable resources. The results obtained enabled the identification of processed vegetables as a food source (in flour and beverage preparation) and as technological goods (for crafts, housing, and furniture). In both cases wild and managed/cultivated resources were identified. Some mortars showed food processing evidence, and others were exclusively used in the technological sphere mentioned above. Nevertheless, it was possible to determine a third kind of artefact in which both processing activities were recorded. Finally, a correlation between physical attributes of mortars and their functionality was achieved both through vegetable particle identification and according to uses referred to in ethnographic sources

    Appropriate Similarity Measures for Author Cocitation Analysis

    We 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 PDF
    We 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

    We 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
