Rock art and technology. A spatio-temporal proposal from the upper basin of the Limari river, north central Chile

Universidad de Buenos Aires. Instituto de Las Culturas; ArgentinaIn this chapter we develop a methodological proposal to overcome the distinction between temporal and spatial dimensions in the technological study of rock art. We built a set of analytical units and variables that render visible the repetitions of technical actions and the aggregation of motifs on the blocks, tested through the analysis of a specific rock art site located along the Ponio River, in the central north of Chile. We consider the repetition of technical actions in each petroglyph and the aggregation of them per block. Bringing rhythms into the study of technology of rock art opens new pathways through which to approach a multiplicity of aspects related to how people lived and produced a spatio-temporal world.Vergara, F. y Basile, M.

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
Rock art in Central and South America: social settins and regional diversity

Institute of Archaeology; InglaterraFil: Basile, Mara Valeria. Consejo Nacional de Investigaciones Científicas y Técnicas. Universidad de Buenos Aires. Instituto de Las Culturas; ArgentinaCentral and South America is a vast region, where a wide range of different societies established, transformed, disappeared, and endured. This kaleidoscope of peoples offers a particularly rich and diverse body of rock art in terms of its historical, technical, visual, and spatial features. The first sections of this chapter briefly introduces the reader to this diversity, as well as to the history of rock art research, presenting and discussing the different theoretical and methodological frameworks used. The authors discuss the role that rock art played—and still plays—for different groups, which they have grouped in terms of their common socioeconomic strategies. The authors argue that rock art research from this region can contribute to the wider understanding of rock art in the world, offering its materialistic and archaeological approaches ranging from the study of social complexity, the domestication of animals, mobility, and memory.Troncoso, A., Armstrong, F. y Basile, M.
