Evolución diacrónica del sistema verbal de movimiento en español: entrar y salir (ss. XII-XV)

Esta investigación es una tesis doctoral que tiene como objetivo el estudio de la evolución semántica de los verbos entrar y salir desde el punto de vista diacrónico en español medieval mediante la aplicación de las herramientas teóricas proporcionadas por la Lingüística cognitiva. A través de un corpus de documentaciones extraídas del Corpus del nuevo diccionario histórico del español de la Real Academia Española y que abarcan el intervalo desde el siglo XIII al XV, se analizan los valores semánticos de ambos verbos con la finalidad de determinar cómo fue desarrollándose su uso, qué significados generaron otros nuevos y cómo se relacionan entre sí los significados de un mismo verbo. Para llevar a cabo esta tarea se ha partido de la Teoría de los prototipos aplicada a la categorización léxica, así como de la Teoría de la metáfora y la metonimia. Asimismo, se ha analizado la estructura sintáctica de cada ejemplo, la selección léxica de los argumentos verbales y la tradición discursiva a la que pertenece cada documentación. De esta forma, es posible, no sólo describir la evolución semántica de ambos verbos, sino completar la información sobre las causas de su desarrollo diacrónico. Finalmente, se establecen las relaciones semánticas de carácter diacrónico existentes entre ambos verbos en tanto que miembros de un mismo grupo léxico, los verbos de movimiento, y se corrobora su vinculación más allá de una relación de antonimia de tipo primario.

On the origin and scope of the second language speech production disadvatage

Los hablantes bilingües tienen un acceso al léxico más lento y menos robusto que los monolingües, incluso cuando hablan en su lengua materna y dominante. Este fenómeno, comúnmente llamado “la desventaja bilingüe” también se observa en hablantes de una segunda lengua en comparación con hablantes de una primera lengua. Una causa que posiblemente contribuya a estas desventajas es el uso de control inhibitorio durante la producción del lenguaje: la inhibición de palabras coactivadas de la lengua actualmente no en uso puede prevenir intrusiones de dicha lengua, pero al mismo tiempo ralentizar la producción del lenguaje. El primer objetivo de los estudios descritos en este informe era testear esta hipótesis mediante diferentes predicciones generadas por teorías de control inhibitorio del lenguaje. Un segundo objetivo era investigar la extensión de la desventaja bilingüe dentro y fuera de la producción de palabras aisladas, así como avanzar en el conocimiento de las variables que la modulan. En lo atingente al primer objetivo, la evidencia obtenida es incompatible con un control inhibitorio global, desafiando la idea de mecanismos específicos en el hablante bilingüe utilizados para la selección léxica. Esto implica que una explicación común para el control de lenguaje y la desventaja bilingüe en el acceso al léxico es poco plausible. En cuanto al segundo objetivo, los resultados muestran que (a) la desventaja bilingüe no tiene un impacto al acceso a la memoria; (b) la desventaja bilingüe extiende a la producción del habla conectada; y (c) similitudes entre lenguas a diferentes niveles de representación así como la frecuencia de uso son factores que modulan la desventaja bilingüe.   

Stressing schizotypy: The modulating role of stress-relieving behaviours and intellectual capacity on functional hemispheric asymmetry.

Relative cognitive impairments are common along the schizophrenia spectrum reflecting potential psychopathological markers. Yet stress, a vulnerability marker in schizophrenia (including its spectrum), is likewise related to cognitive impairments. We investigated whether one such cognitive marker (attenuated functional hemispheric asymmetry) during stressful life periods might be linked to individuals' schizotypal features or rather to individuals' stress-related experiences and behaviours. A total of 58 students performed a left hemisphere dominant (lateralised lexical decisions) and right hemisphere dominant (sex decisions on composite faces) task. In order to account for individual differences in stress sensitivity we separated participants into groups of high or low cognitive reserve according to their average current marks. In addition, participants filled in questionnaires on schizotypy (short O-LIFE), perceived stress, stress response, and a newly adapted questionnaire that enquired about potential stress compensation behaviour (elevated substance use). The most important finding was that enhanced substance use and cognitive disorganisation contributed to a right and left hemisphere shift in language dominance, respectively. We discuss that (i) former reports on right hemisphere shifts in language dominance with positive schizotypy might be explained by an associated higher substance use and (ii) cognitive disorganisation relates to unstable cognitive functioning that depend on individuals' life circumstances, contributing to published reports on inconsistent laterality-schizotypy relationships.

La geografía en los relatos de viajes castellanos del ocaso de la Edad Media : análisis del discurso y léxico

Résumé Le travail poursuit un triple objectif: A) présenter la place qu'occupe la géographie physique et la géographie urbaine dans un corpus de cinq récits de voyages castillans de la fin du Moyen-Age, en se centrant particulièrement sur le relief, les eaux continentales, les mers, les côtes, le climat, la végétation, la faune et les villes; B) analyser les ressources discursives dont se servent les rédacteurs pour transmettre ces contenus; C) et réunir le lexique géographique des textes, en l'organisant autour des thématiques mentionnées, en définissant les mots et en faisant ressortir leur valeur dans le contexte discursif. L'étude est introduite par une analyse de la situation communicative dans laquelle se forgent les récits du corpus: contexte historique, social, culturel et textuel, d'une part; identité des voyageurs- rédacteurs, identité des destinataires, et objectifs divers aussi bien des voyages que de leur mise en écriture, d'autre part. De cette analyse ressortent quelques intentions et préoccupations communes aux voyageurs-rédacteurs qui pourraient se résumer en: A) une conscience de la difficulté du voyage; B) une conscience de réaliser un mouvement vers un monde éloigné et étrange; C) une volonté de transmettre des connaissances sur le monde; D) un désir de présenter ce qu'ils racontent comme le fruit d'une expérience vécue et de le faire avec véracité. L'analyse introductoire montre également que cette approche du voyage et la conception du récit qui en découle déterminent le choix de certains contenus géographiques et une façon précise d'exposer l'expérience du voyage: les textes transmettent des connaissances sur le monde et construisent un discours informatif sur l'espace, tout en décrivant un univers étrange et en insistant sur leur caractère testimonial. Le corps du travail est articulé en trois parties. Le premier volet permet de faire émerger la place réservée à la géographie, surtout physique, dans les récits. Il dévoile l'intérêt naissant manifesté par les voyageurs-rédacteurs pour la géographie physique et témoigne de la typologie diversifiée des descriptions urbaines. Il éclaire également le rapport intime liant les thématiques privilégiées dans les textes, les intérêts des rédacteurs et de leur public, et les objectifs de chaque récit. La géographie transmise est non-livresque, issue de l'expérience et, par conséquent, partielle. Le deuxième volet montre le fonctionnement d'une description qui est porteuse d'informations sur l'espace et qui véhicule des savoirs sur le monde, en particulier sur le monde inconnu. Les opérations de nommer, mesurer et adjectiver l'espace parcouru, en le comparant ensuite à l'espace connu sont analysées en détail. Cette partie du travail met en exergue les connaissances, les croyances et les valeurs partagées entre rédacteurs et récepteurs sur lesquelles se construit un discours destiné à transmettre de nouveaux savoirs sur le monde. Les textes se présentent, en outre, comme un témoignage basé sur l'expérience des voyageurs: l'importance de l'information acquise par l'ouïe porte les rédacteurs à incorporer dans leurs récits de nombreuses voix qui racontent le monde et fait du discours géographique un discours clairement polyphonique. Enfin, le troisième volet réunit pour la première fois le lexique géographique castillan en usage à la fin du Moyen-Âge. Procédant de textes rédigés par des non spécialistes, il nous permet d'évaluer les connaissances géographiques d'un homme de l'époque et inclut définitions, exemples d'usage des mots en contexte, données étymologiques, diachroniques, morphosyntaxiques, sémantiques et encyclopédiques. Dans son ensemble, la thèse témoigne de l'intérêt d'une approche des récits de voyage par le triple axe thématique, discursif et lexical.

Selective attention to emotional stimuli: What IQ and Openness do, and emotional intelligence does not

We examined how general intelligence, personality, and emotional intelligence-measured as an ability using the MSCEIT-predicted performance on a selective-attention task requiring participants to ignore distracting emotion information. We used a visual prime in which participants saw a pair of faces depicting emotions; their task was to focus on one of the faces (the target) while ignoring the other (the distractor). Next, participants categorized a string of letters (word or nonword), which was either congruent to the target or the distractor. The speed of response to categorizing the string was recorded. Given the emotional nature of the stimuli and the emotional information processing involved in the task, we were surprised to see that none of the MSCEIT branches predicted performance. However, general intelligence and openness to experience reduced response time.

Noninvasive functional and structural exploration of human subcortical structures with high resolution

Projecte de recerca elaborat a partir d’una estada al Max Planck Institute for Human Cognitive and Brain Sciences, Alemanya, entre 2010 i 2012. El principal objectiu d’aquest projecte era estudiar en detall les estructures subcorticals, en concret, el rol dels ganglis basals en control cognitiu durant processament lingüístic i no-lingüístic. Per tal d’assolir una diferenciació minuciosa en els diferents nuclis dels ganglis basals s’utilitzà ressonància magnètica d’ultra-alt camp i alta resolució (7T-MRI). El còrtex prefrontal lateral i els ganglis basals treballant conjuntament per a mitjançar memòria de treball i la regulació “top-down” de la cognició. Aquest circuit regula l’equilibri entre respostes automàtiques i d’alt-ordre cognitiu. Es crearen tres condicions experimentals principals: frases/seqüències noambigües, no-gramatical i ambigües. Les frases/seqüències no-ambigües haurien de provocar una resposta automàtica, mentre les frases/seqüències ambigües i no-gramaticals produïren un conflicte amb la resposta automàtica, i per tant, requeririen una resposta de d’alt-ordre cognitiu. Dins del domini de la resposta de control, la ambigüitat i no-gramaticalitat representen dues dimensions diferents de la resolució de conflicte, mentre per una frase/seqüència temporalment ambigua existeix una interpretació correcte, aquest no és el cas per a les frases/seqüències no-gramaticals. A més, el disseny experimental incloïa una manipulació lingüística i nolingüística, la qual posà a prova la hipòtesi que els efectes són de domini-general; així com una manipulació semàntica i sintàctica que avaluà les diferències entre el processament d’ambigüitat/error “intrínseca” vs. “estructural”. Els resultats del primer experiment (sintax-lingüístic) mostraren un gradient rostroventralcaudodorsal de control cognitiu dins del nucli caudat, això és, les regions més rostrals sostenint els nivells més alts de processament cognitiu

Summarization of specialized discourse: the case of medical articles in Spanish

In this article, we present the current state of our work on a linguistically-motivated model for automatic summarization of medical articles in Spanish. The model takes into account the results of an empirical study which reveals that, on the one hand, domain-specific summarization criteria can often be derived from the summaries of domain specialists, and, on the other hand, adequate summarization strategies must be multidimensional, i.e., cover various types of linguistic clues. We take into account the textual, lexical, discursive, syntactic and communicative dimensions. This is novel in the field of summarization. The experiments carried out so far indicate that our model is suitable to provide high quality summarizations.

Automatic Detection of Non-deverbal Event Nouns for Quick Lexicon Production

In this work we present the results of experimental work on the development of lexical class-based lexica by automatic means. Our purpose is to assess the use of linguistic lexical-class based information as a feature selection methodology for the use of classifiers in quick lexical development. The results show that the approach can help reduce the human effort required in the development of language resources significantly.

Membership and internal democracy. Immigrant organisations in the city of Oslo

Immigrant organisations in the City of Oslo receive support from the government for their daily operation. In order to receive such support, each organisation must be membership-based and have internal democratic procedures. This paper raises the question of how we can understand this combination of support for ethnic based organisations and requirements of membership and internal democracy. It explores the usefulness of two partly overlapping ways of understanding this policy and discusses their interrelationship. Firstly, within the context of the crisis of multiculturalism, the paper discusses whether this combination is based on the aim of strengthening the organisations’ procedural commitment to liberal-democratic principles. Secondly, the paper analyses whether requirements of membership and internal democracy can mainly be understood within the framework of the Nordic model of voluntary organisation. By comparing the policy at three empirical levels, the paper concludes that this combination can mainly be understood within the framework of the traditional historical Nordic model, but that there is an ambiguity in this policy related to minority rights.

Spotting Translationese in two Corpora of Original and Translated Catalan Texts: an Empirical Approach

This research investigates the phenomenon of translationese in two monolingual comparable corpora of original and translated Catalan texts. Translationese has been defined as the dialect, sub-language or code of translated language. This study aims at giving empirical evidence of translation universals regardless the source language.Traditionally, research conducted on translation strategies has been mainly intuition-based. Computational Linguistics and Natural Language Processing techniques provide reliable information of lexical frequencies, morphological and syntactical distribution in corpora. Therefore, they have been applied to observe which translation strategies occur in these corpora.Results seem to prove the simplification, interference and explicitation hypotheses, whereas no sign of normalization has been detected with the methodology used.The data collected and the resources created for identifying lexical, morphological and syntactic patterns of translations can be useful for Translation Studies teachers, scholars and students: teachers will have more tools to help students avoid the reproduction of translationese patterns. Resources developed will help in detecting non-genuine or inadequate structures in the target language. This fact may imply an improvement in stylistic quality in translations. Translation professionals can also take advantage of these resources to improve their translation quality.

Hindsight judgement on ambiguous episodes of suspected infection in critically ill children: poor consensus amongst experts?

Few episodes of suspected infection observed in paediatric intensive care are classifiable without ambiguity by a priori defined criteria. Most require additional expert judgement. Recently, we observed a high variability in antibiotic prescription rates, not explained by the patients' clinical data or underlying diseases. We hypothesised that the disagreement of experts in adjudication of episodes of suspected infection could be one of the potential causes for this variability. During a 5-month period, we included all patients of a 19-bed multidisciplinary, tertiary, neonatal and paediatric intensive care unit, in whom infection was clinically suspected and antibiotics were prescribed ( n=183). Three experts (two senior ICU physicians and a specialist in infectious diseases) were provided with all patient data, laboratory and microbiological findings. All experts classified episodes according to a priori defined criteria into: proven sepsis, probable sepsis (negative cultures), localised infection and no infection. Episodes of proven viral infection and incomplete data sets were excluded. Of the remaining 167 episodes, 48 were classifiable by a priori criteria ( n=28 proven sepsis, n= 20 no infection). The three experts only achieved limited agreement beyond chance in the remaining 119 episodes (kappa = 0.32, and kappa = 0.19 amongst the ICU physicians). The kappa is a measure of the degree of agreement beyond what would be expected by chance alone, with 0 indicating the chance result and 1 indicating perfect agreement. CONCLUSION: agreement of specialists in hindsight adjudication of episodes of suspected infection is of questionable reliability.

Frame detection over the semantic web

In the past, research in ontology learning from text has mainly focused on entity recognition, taxonomy induction and relation extraction. In this work we approach a challenging research issue: detecting semantic frames from texts and using them to encode web ontologies. We exploit a new generation Natural Language Processing technology for frame detection, and we enrich the frames acquired so far with argument restrictions provided by a super-sense tagger and domain specializations. The results are encoded according to a Linguistic MetaModel, which allows a complete translation of lexical resources and data acquired from text, enabling custom transformations of the enriched frames into modular ontology components.

Language lateralization in early and late bilinguals using an international vocabulary

In lateralized Lexical Decision Tasks (LDT), accuracy is commonly higher and reaction times are commonly faster for right visual field (RVF) than left visual field (LVF) presentations. This visual field differences are thought to demonstrate the left hemisphere's dominance for language. Unfortunately, different tasks and words are used between studies and languages making direct comparisons difficult. For example, high frequency words show a performance advantage over low frequency words. Moreover, demographic variables impact on lateralized behavior such as language knowledge (one versus several, early acquired versus late acquired). We here aim to alleviate some of these obstacles by presenting results from a lateralized LDT for which we selected words between 4 and 6 letters used in five different languages, i.e. English, French, German, Dutch and Italian. In this first study using these words, we compared performance of right- and left-handed students being either early or late bilinguals (acquired before or after the age of 6 years) from a French-speaking University in Switzerland. Results showed a left hemispheric advantage (accuracy, reaction times) for all groups, with a trend for early as compared to late bilinguals to be less accurate and taking longer in lexical decisions. These results show that the current words result in solid visual field differences, and do so irrespective of how many languages are spoken. While early bilinguals might experience a slight performance disadvantage, it was not affecting visual field differences.

8-month non-use of a language. A case tudy. A longitudinal study of the effects on non use of one of the languages (Spanish) of a German L1 multilingual

Under the Dynamic Model of Multilingualism multilinguals are especially vulnerable to language attrition. It was the aim of the present study to verify if this was the case and to observe whether the different linguistic skills (receptive vs. descriptive) and the different linguistic levels (syntactic, lexical, morphological, etc.) would be affected equally.Data were gathered longitudinally by means of a language test for the subject’s reading, writing, listening and speaking skills as well as her knowledge of grammar and vocabulary. Although the overall accuracy remained intact and no proof for attrition in the receptive skills was found, the productive skills - mainly fluency - were shown to have suffered from language attrition. This was demonstrated by an increase in the number of pauses, hesitations, repetitions and self-corrections among others and decrease in the percentage of error-free clauses and decrease in the clause length, in oral and written fluency respectively.
