La aproximación experimental sobre el discurso de la pobreza
No full textLos postulados indicados, procedentes del análisis discurso, constituyen la base para diseñar una investigación de carácter experimental que permita avanzar en la comprensión del fenómeno estudiado: la espectacularización en el discurso sobre la pobreza en Colombia y su efecto sobre la sociedad (Pardo y Hernández 2007). El reto consiste en traducir las categorías de análisis extraídas de este enfoque semiótico-discursivo a un formato manipulable experimentalmente que permita la comprobación de un efecto (operacionalización de las variables) (Gries 2008). Dicho
en otras palabras, se precisa, por un lado, encontrar la manera de codificar la espectacularización a través de un solo recurso lingüístico o semiótico, aislando un único factor de análisis, por otro lado, es necesario hallar un efecto real que refleje la parálisis cognitiva, por ejemplo, demostrando una falta de comprensión. El proceso de la operacionalización no está exento de dificultades, pues ambos acercamientos científicos, el semiótico-discursivo y el experimental, parten de principios muy diferentes
Modelos cognitivos de procesamiento y formación de representaciones mentales
No full textLa comprensión de un texto implica que el lector es capaz de formarse representaciones mentales al combinar el input externo codificado por el texto con el input interno procedente de su conocimiento previo (van Dijk y Kintsch 1983). Las representaciones mentales se obtienen, por tanto, a partir de información lingüística y no lingüística (van Dijk y Kintsch 1983) sobre la construcción de modelos situacionales para el procesamiento del discurso. Desde un punto de vista relevantista (Sperber y Wilson 1998), el procesamiento de esta información que deriva en las representaciones se lleva a cabo en tres fases: la descodificación, basada por completo en procesos semánticos, la obtención de la explicatura, que
completa el significado semántico recurriendo a información pragmática, y la construcción de un modelo situacional con la recuperación de implicaturas que son contrastadas con el conocimiento previo del lector (Escandell 2005)
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
Die kognitive Perspektive
Get PDFChristiane von Stutterheim's scientific work ranges from language typology to sentence and text production, to questions of second and foreign language acquisition. Her particular contribution lies in emphasizing linguistics as an important contributor to cognitive science. The Festschrift attempts to reflect the breadth of Christiane von Stutterheim's research activities.Christiane von Stutterheim spannt in ihrer wissenschaftlichen Arbeit den Bogen von der Sprachtypologie über die Satz- und Textproduktion bis zu Fragen des Zweit- und Fremdsprachenerwerbs. Ihr besonderer Beitrag für die Forschung liegt in der Betonung der Linguistik als wichtige Teildisziplin der Kognitionswissenschaften. Die Festschrift versucht mit ihren Beiträgen die Breite von Christiane von Stutterheims Forschungstätigkeit widerzuspiegeln
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
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
