Técnicas de Medición I
Full text linkEn la recolección de datos antropométricos que se utilizan en medicina, deporte, crecimiento y desarrollo y características físicas de la población, es necesario el empleo de un procedimiento adecuado (estandarizado) para medir al individuo. Las técnicas que se efectúen deben estar estandarizadas, los instrumentos en perfecto estado y los medidores debidamente entrenados, de modo que los datos que se obtengan puedan ser usado para elaborar índices, comparar con otras poblaciones o áreas con un alto grado de confiabilidad.Fil: Labourdette, Verónica Beatriz; Leiva, Rodolfo Daniel; Morande, Roberto Aníbal; Zapata, Jorge Ángel.

The geometry of the Cartesian ego: figuration and geometric imagination in the constitution of an order of reasons
No full textFil: Leiva, Rodolfo. Universidad Nacional del Litoral. Facultad de Humanidades y Ciencias; Argentina.La descripción figurativa de los fenómenos constituye el principio heurístico fundamental de la filosofía natural cartesiana. La posibilidad de describir figurativamente problemas aritméticos, el comportamiento de los fenómenos naturales y los mecanismos corporales implicados en el conocimiento, no sólo permite explicar con la claridad y la evidencia de la geometría una multiplicidad de fenómenos aparentes sino además formular leyes generales que, de manera hipotética, describen los mecanismos generales de la materia, es decir, permite formular leyes generales de la Naturaleza.
La descripción geométrica de la estructura hipotética de la Naturaleza representa un «orden según las razones» que nos permite conocer con claridad y evidencia el orden natural, pero requiere, no obstante, una fundamentación metafísica que permita validar esta relación con el orden conocido.
A tal fin, la experiencia meditativa del ego, «ego cogito ergo sum», brinda una primera verdad absoluta «cierta e inconmovible», «necesariamente verdadera» mientras «se concibe o se expresa», que funda y sirve de canon para toda verdad del ordo cognoscendi. La veracidad de la experiencia cogitante (que afirma y niega, quiere y no quiere, que también «imagina») permite validar la actividad figurativa con la cual se constituye la estructura racional del orden conocido, la imaginación geométrica, la «disposición o facultad» ínsita en la naturaleza del ego gracias a la cual puede «espontáneamente» concebir ideas racionales de la extensión y representarlas imaginariamente. Así, podemos establecer que es la propia naturaleza geométrica del ego la que constituye la estructura racional del orden conocido.The figurative description of phenomena constitutes the fundamental heuristic principle of Cartesian natural philosophy. The possibility of figuratively describing arithmetical problems, the behavior of natural phenomena and the bodily mechanisms involved in knowledge, not only allows to explain with the clarity and evidence of geometry a multiplicity of apparent phenomena but also to formulate general laws that, hypothetically, describe the general mechanisms of matter, that is, it allows formulating general laws of nature.
The geometric description of the hypothetical structure of Nature represents an "order of reasons" that allows us to clearly understand the natural order but requires, however, a metaphysical foundation to validate this relationship with the known order.
To this end, the meditative experience of the ego, «ego cogito ergo sum», provides a first absolute truth «certain and unshakable», «necessarily true» while «it is conceived or expressed», which founds and serves as a canon for all truth of ordo cognoscendi. The veracity of the cogitative experience (which affirms and denies, is willing and unwilling, and also «imagine») allows to validate the figurative activity with which the rational structure of the known order is constituted, the geometric imagination, the «disposition or faculty» inherent in the nature of the ego thanks to which it can "spontaneously" conceive rational ideas of extension and represent them imaginatively. Thus, we can establish that it is the very geometric nature of the ego that constitutes the rational structure of the known order

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
