La artesan?a en la zona sur de la provincia de Las Tunas: La cester?a
No full textLa siguiente investigaci?n es fruto de un acercamiento a la artesan?a en el sur de Las Tunas; enfatizando en las caracter?sticas m?s representativas de la cester?a, por ser ?ste uno de los g?neros portadores de una tradici?n que se ha mantenido vigente desde generaciones pasadas. Persigue como objetivo revelar los rasgos y elementos que distinguen a la cester?a en la zona sur del territorio tunero, tomando como principal fuente de informaci?n los testimonios de sus creadores. Se encuentra conformada por: resumen, introducci?n, tres cap?tulos, conclusiones, recomendaciones, bibliograf?a, notas y anexos. Despu?s de haberse realizado un an?lisis se determinaron las categor?as que conformaron el eje te?rico, ellas son cultura popular tradicional y artesan?a popular, las cuales fueron sometidas a reflexiones te?ricas. Para el desarrollo de esta investigaci?n se elabor? un cuerpo metodol?gico conformado por enfoques, perspectivas, paradigma, as? como los m?todos y las t?cnicas que permitieron la obtenci?n de una valios?sima informaci?n para poder realizar, no solo la caracterizaci?n de la cester?a en el sur tunero, sino tambi?n, determinar los elementos m?s significativos de este quehacer artesanal. El esbozo acerca de la artesan?a en Cuba, su origen, condicionamiento hist?rico y principales manifestaciones culturales, as? como la caracterizaci?n de la cester?a en la zona sur de Las Tunas y otros rasgos que condicionaron su surgimiento y desarrollo constituyeron los principales resultados de la presente investigaci?n
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

Full text linkVariations 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
Organic substrates for novel printed sensors in neural interfacing: A measurement method for cytocompatibility analysis
No full textAdvances in bioelectronics as interdisciplinary field combining electronics with novel materials for targeting biological monitoring have brought a strong acceleration in the development of sensors for neural interfaces. However, the success of any implantable device comes along with properties such as long-term stability and optimal cytocompatibility. Thus, the need to improve the reliability and reproducibility of quantitative methods for analyzing and comparing cells-substrate interaction of novel heterogeneous materials has become more and more compelling. To this aim, a systematization of the approach to analyze cytocompatibility assays appears as important as the standardization of the acquisition conditions themselves.. In this picture, the paper proposes a user-friendly toolbox able to improve the reliability of the analysis of fluorescence images from cultured organic materials. The first section, allowing a proper customization of several parameters, performs an optimal automatized segmentation of the image with an adaptive threshold strategy, evaluating cell parameters distribution on the substrate. The second one estimates the uncertainty in the evaluation of cell number and provides cell density maps at different scales. The comparison among different organic semiconductors demonstrated the possibility to use the software to compare the effect of different materials on cell parameters. Future works will address the correlation of those results from cell imaging with correspondent maps of the most peculiar properties of each cultured substrate
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
