Teoría arqueológica en América del Sur: Textos, pretextos y contextos
Get PDFCuando analizamos la bibliografía y las publicaciones arqueológicas respecto a la teoría arqueológica en América del Sur surgen varios interrogantes, pero en realidad, ¿A qué se refieren estos documentos cuando mencionan o se remiten a tal teoría arqueológica? Admitimos que es difícil denotar los contenidos y la extensión de dicho concepto. Su imprecisión igualmente compromete toda posibilidad de poner en diálogo los contenidos semánticos, planteamiento que incrementa nuestra confusión cuando estudiamos los pocos textos especializados sobre este continente. Por lo tanto, nuestra tarea es analizar lo que para los arqueólogos, y aún para los filósofos, significa el concepto teoría arqueológica; y, por ende, aceptar que los usos y funciones con que hoy se emplea esta teoría cubren un área heterogénea y ambigua. Muchos de los textos que discursan acerca de la teoría arqueológica pueden ser meras propuestas y respuestas a específicos contextos académicos y geográficos, contextos que incluso varían con el tiempo
Tiempos naturales; tiempos construidos
Get PDFThe author shows how the time can be measured from multiplex calendars that are symbolical constructions, plurals and diverse. So the time is not a real entity but an existent abstraction in the discourse and regulated by the space related to environment. Puts emphasis in the velocity and in the rhythms of the changes that determines a society and its culture that generates an own temporality. It relies in a taxonomy of the times that segregates the personal time, the public time and the sedimentary time. Runs over the mistakes produced while extracting conclusions about social conducts that indeed have a start point strictly individual. It is pointed the impossibility of these reductions as well of its counterpart, the macro-reductionism that tries, with no chances, to explain little scale phenomenon through data obtained in a macro level. Micro and macro are not just different extentions, they have fundamentally diverse properties, which are not interchangeable. The summatory of the individual patterns does not let us to foretell the group, because the macroprocesses produce its own phenomenon with forms of articulation that do not exist in the micro-processes.El autor muestra como el tiempo puede ser medido desde múltiples calendarios que son construcciones simbólicas plurales y diversas. Así el tiempo no es una entidad real sino una abstracción existente en el discurso y regulado por el espacio en tanto medio ambiente. Pone énfasis en la velocidad y en los ritmos de los cambios que determinan a una sociedad y su cultura que generan una temporalidad propia. Se apoya en una taxonomía de los tiempos que discrimina el tiempo personal, el tiempo público, y el tiempo sedimentario. Recorre los equívocos que se producen al extraer conclusiones sobre conductas sociales que en realidad tienen un punto de partida estrictamente individual. Se señala la imposibilidad de estos reduccionismos como también de su contrapartida, el macro reduccionismo que intenta infructuosamente explicar fenómenos de pequeña escala a través de datos recogidos en un macro nivel. Lo micro y lo macro no son solo extensiones distintas sino que tienen fundamentalmente propiedades diversas que no son intercambiables. La sumatoria de las pautas individuales no nos permite predecir el conjunto porque los macro procesos producen sus propios fenómenos con formas de articulación que no existen en los microprocesos
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
Patrimonio: transgresión a la dinámica cultural
Get PDFEn estas breves consideraciones procuraremos exponer los fundamentos de la polarización existente entre la labor de los investigadores y un "uso del pasado", traducido este último con el término "patrimonio".- Dicha polarización, que parece no haber sido suficientemente señalada, dificulta y hasta impide la evaluación de las distintas concepciones que el término adquiere, puesto que la misma se halla en el origen mismo de las funciones y definiciones asignadas a ambas partes. Entendemos que el par investigación-patrimonio, no es una dicotomía: es una real antinomia.Facultad de Ciencias Naturales y Muse
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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
