Dibujos solares: Los caballos de espinacas Sobre antotipias y afectividad ambiental=Solar Drawings: On anthotypies and environmental affectivity
No full textEste trabajo propone una reflexión, a partir de una experiencia de producción de dibujos solares, sobre prácticas de producción de imágenes mediante la técnica de la antotipia y de sus posibilidades a la hora de generar mayor afectividad ambiental, sensibilidad y empatía ecológica. Se trata de pensar posibilidades y compartir procesos donde la producción de imagen esté vinculada a alimentos y vegetales y se vea determinada por la climatología y sus tiempos, creando imágenes frágiles y efímeras que contribuyan a habitar preguntas del pensamiento crítico actual desde la práctica.This work suggests to reflect on an experience of solar drawing production and on image production practices through the antitype technique and its possibilities when it comes to generating greater environmental affectivity, sensitivity and ecological empathy. It is about thinking on its possibilities and sharing some processes where image production is linked to food and vegetables, as well as determined by the weather and its timings, creating fragile and ephemeral images that contribute, through its practice, to dwell on questions of current critical thinking
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
Rescatando los objetos epistémicos del diseño especulativo
Full text linkEste artículo explora el papel de los objetos epistémicos en el diseño especulativo proponiendo un recorrido que va desde los orígenes de esta práctica en la década de los noventa hasta su consolidación como método de investigación, pasando por el surgimiento del diseño ficción en la primera década del presente siglo. Tomando nota de las revisiones críticas y de las limitantes detectadas en los últimos años, se busca rescatar y analizar el papel de los prototipos diegéticos como lugares de investigación. Se plantea que los prototipos son una posible encarnación de lo que Rheinberger llama “objetos epistémicos” o “cosas epistémicas”. Así concebidos, estos prototipos permiten conocer diseñando y revisitar el carácter experimental de un método que nos lleva a explorar y materializar lo que aún no sabemos.
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
Entre grafos y bits
Full text linkEste texto se propone ahondar en las intersecciones de lo analógico y lo digital,
en el encuentro de la baja y la alta tecnología. Tomando consciencia de la
materialidad de ambas esferas para pensar desde ahí en objetos, prácticas de
dibujo y documentación que puedan aportar otras formulaciones aplicables a
métodos de investigación. Entre grafos y bits, diseccionaremos un objeto, el
#relatograma, analizaremos su ecología y propondremos una reflexión acerca
de su condición digital que genera paisajes por agregación #coreograma,
explorando así su capacidad de ser reporte y aporte cognitivo
