El teatre de Harold Pinter a Barcelona

Aquest treball analitza l’impacte que ha tingut el dramaturg Harold Pinter a la ciutat de Barcelona des de la primer vegada que s’hi va representar, l’any 1963, fins que es va celebrar el festival Tardor Pinter, l’any 1996. La investigació s’ha fet, sobretot, a partir de la premsa de l’època però també s’ha tingut en compte material gràfic i entrevistes. L’objectiu ha estat observar l’evolució de l’opinió que suscitaven les obres d’aquest autor i com, de mica en mica es va arribar a convertir en un model creatiu per al grup d’El Teatro Fronterizo, encapçalat per José Sanchis Sinisterra.

Assessment and reuse of contents in the competence-based educational platform InterMediActor

This paper describes a failure alert system and a methodology for content reuse in a new instructional design system called InterMediActor (IMA). IMA provides an environment for instructional content design, production and reuse, and for students’ evaluation based in content specification through a hierarchical structure of competences. The student assessment process and information extraction process for content reuse are explained.

Aprendizaje basado en la interacción de usuarios para búsqueda y recuperación de imágenes

Se propone, al amparo del proyecto “Nuevos Algoritmos para la Gestión Eficiente de Contenidos Multimediaen Redes de Comunicaciones Móviles” (NAGEC), un nuevo mecanismo para la búsqueda y recuperación deimágenes basado en realimentación de relevancia. La arquitectura propuesta se compone de una red neuronal yun tesauro. La red neuronal extrae de las imágenes dos parámetros: textura y color. El tesauro recoge lasrelaciones semánticas existentes entre los términos descriptores de las imágenes de la base de datos VisTex.Ambos componentes se relacionan mediante un modelo de realimentación de relevancia que, a través de lasinteracciones del usuario con el tesauro durante el proceso de búsqueda, permite a la red aprender relacionessemánticas inherentes a las imágenes.

Hierachy-based methodology for producing educational contents with maximal reutilization

Computer based training or distance education are facing dramatic changes withthe advent of standardization efforts, some of them concentrating in maximal reuse.This is of paramount importance for a sustainable -cost affordable- production ofeducational materials. Reuse in itself should not be a goal, though, since manymethodological aspects might be lost. In this paper we propose two contentproduction approaches for the InterMediActor platform under a competence-basedmethodology: either a bottom-up approach where content is designed from scratchor a top-down methodology where existing material can be gradually adapted tofulfil requisites to be used with maximal flexibility into InterMediActor.

Fishery of the Goliath grouper, Epinephelus itajara (Teleostei: Epinephelidae) based on local ecological knowledge and fishery records in Yucatan, Mexico

The Goliath grouper, Epinephelus itajara, a large-bodied (similar to 2.5 m TL, > 400 kg) and critically endangered fish (Epinephelidae), is highly Vulnerable to overfishing. Although protected from fishing in many countries, its exploitation in Mexico is unregulated; a situation that puts its populations at risk. Fishery records of E. itajara are scarce, which prevents determination of its fishery status. This work aimed to elucidate the E itajara fishery in the northern Yucatan Peninsula by 1) analyzing available catch records and 2) interviewing veteran fishermen (local ecological knowledge) from two traditional landing sites: Dzilam de Bravo and Puerto Progreso. Historic fishery records from two fishing cooperatives were analyzed in order to elucidate the current situation and offer viable alternatives for conservation and management. Catches have decreased severely. Local knowledge obtained from fishermen represented a very important source of information for reconstructing the fisheries history of this species. Conservation measures that incorporate regional and international regulations on critically endangered fish species are suggested

Otolith shape analysis as a tool for population discrimination of the white grunt (Haemulon plumieri) stock in the northern coast of the Yucatan Peninsula, Mexico

In this study, the population structure of the white grunt (Haemulon plumieri) from the northern coast of the Yucatan Peninsula was determined through an otolith shape analysis based on the samples collected in three locations: Celestún (N 20°49",W 90°25"), Dzilam (N 21°23", W 88°54") and Cancún (N 21°21",W 86°52"). The otolith outline was based on the elliptic Fourier descriptors, which indicated that the H. plumieri population in the northern coast of the Yucatan Peninsula is composed of three geographically delimited units (Celestún, Dzilam, and Cancún). Significant differences were observed in mean otolith shapes among all samples (PERMANOVA; F2, 99 = 11.20, P = 0.0002), and the subsequent pairwise comparisons showed that all samples were significantly differently from each other. Samples do not belong to a unique white grunt population, and results suggest that they might represent a structured population along the northern coast of the Yucatan Peninsula

Helena Valentí, fúria i traducció

La filòloga i novel·lista Helena Valentí i Petit (Barcelona, 1940-1990) s’exilià de ben jove a Anglaterra, on buscà en la traducció el mitjà de vida. Entre altres autors i autores, traslladà al castellà William Blake, Marilyn French, Nicholas Guild, Najib Mahfuz, Harold Robbins, Bernice Rubens, Roger T. Taylor i Doris Lessing, de la qual traduí El quadern daurat. De retorn a Catalunya, el 1974, decidí compaginar la traducció amb la narrativa pròpia. Girà a la llengua catalana Al far i Una cambra pròpia de l’anglesa Virginia Woolf i La garden party i altres contes i Un home casat i altres crueltats de la neozelandesa Katherine Mansfield. En els anys vuitanta traslladà El factor humà de Graham Greene i Jo, Claudi de Robert Graves, i féu una breu incursió en la narrativa per a joves. Viatges indiscrets de Lisa St. Aubin, un recull de contes d’autores del segle XX, fou l’última traducció.
