Combination of diffusion tensor and functional magnetic resonance imaging during recovery from the vegetative state

Background: The rate of recovery from the vegetative state (VS) is low. Currently, little is known of the mechanisms and cerebral changes that accompany those relatively rare cases of good recovery. Here, we combined functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI) to study the evolution of one VS patient at one month post-ictus and again twelve months later when he had recovered consciousness. Methods fMRI was used to investigate cortical responses to passive language stimulation as well as task-induced deactivations related to the default-mode network. DTI was used to assess the integrity of the global white matter and the arcuate fasciculus. We also performed a neuropsychological assessment at the time of the second MRI examination in order to characterize the profile of cognitive deficits. Results: fMRI analysis revealed anatomically appropriate activation to speech in both the first and the second scans but a reduced pattern of task-induced deactivations in the first scan. In the second scan, following the recovery of consciousness, this pattern became more similar to that classically described for the default-mode network. DTI analysis revealed relative preservation of the arcuate fasciculus and of the global normal-appearing white matter at both time points. The neuropsychological assessment revealed recovery of receptive linguistic functioning by 12-months post-ictus. Conclusions: These results suggest that the combination of different structural and functional imaging modalities may provide a powerful means for assessing the mechanisms involved in the recovery from the VS.

Online brands: Branding, possible worlds, and interactive grammars

This paper proposes to reflect from a semiotic perspective on the transformation that brands have undergone since the rise of the Internet. After a brief theoretical introduction to digital communication and the semiotics of brands, the case of the Google brand is analyzed by applying concepts of generative and interpretive semiotics. The paper holds that the iconic and linguistic enunciations are secondary with respect to interaction. In digital media interaction — the interactive experience that the Internet user lives — is a fundamental component of the hypermedia cocktail and occupies a central position in the brand building process. The article concludes with some of the questions and special characteristics raised by so-called eBranding.

Escriure (a) la frontera : autores bilingües traductores culturals

La creixent literatura postcolonial en països prèviament colonitzats, així com la creixent literatura de minories en països primermundistes sovint posen de manifest un mestissatge cultural que queda palès en la llengua. Les escriptores bilingües d’aquests països ocupen un espai cultural fronterer, com a mínim, a cavall de dos mons, a cavall de dues identitats i a cavall de dues llengües. La seva lectura del món no tan sols posa de manifest la problemàtica de la pluralitat lingüística i la diversitat d’identitats en les persones humanes, sinó que també acara l’essencialisme de les nocions d’equivalència que les expressions culturals dominants han presentat al llarg de la història de la traducció.

Ironías de la ironía: argumento dialéctico, figura retórica o categoría estética

[spa] El artículo plantea una breve revisión de la idea de ironía desde el punto de vista de la retórica y sus derivaciones en algunos de los estudios lingüísticos del siglo XX. Se parte de la clasificación tradicional de la ironía socrática, la ironía retórica y la ironía romántica para centrar el análisis en aspectos básicos del fenómeno irónico tales como la oposición, la verosimilitud, la complicidad con el intérprete o el papel desempeñado por el contexto. [eng] This article is a brief review of the concept of irony from the point of view of rhetoric and its influences in some of the twentieth century linguistic studies. The review begins with the traditional classification of Socratic irony, rhetoric irony and romantic irony in order to focus the analysis on some fundamental elements of ironic phenomenon such as opposition, verisimilitude, camaraderie with the interpreter or the role played by the context.

ClInt: A bilingual Spanish-Catalan spoken corpus of clinical interviews

In this paper we present ClInt (Clinical Interview), a bilingual Spanish-Catalan spoken corpus that contains 15 hours of clinical interviews. It consists of audio files aligned with multiple-level transcriptions comprising orthographic, phonetic and morphological information, as well as linguistic and extralinguistic encoding. This is a previously non-existent resource for these languages and it offers a wide-ranging exploitation potential in a broad variety of disciplines such as Linguistics, Natural Language Processing and related fields.

Identity, non-identity, and near-identity: Addressing the complexity of coreference

This article examines the mainstream categorical definition of coreference as "identity of reference." It argues that coreference is best handled when identity is treated as a continuum, ranging from full identity to non-identity, with room for near-identity relations to explain currently problematic cases. This middle ground is needed to account for those linguistic expressions in real text that stand in relations that are neither full coreference nor non-coreference, a situation that has led to contradictory treatment of cases in previous coreference annotation efforts. We discuss key issues for coreference such as conceptual categorization, individuation, criteria of identity, and the discourse model construct. We redefine coreference as a scalar relation between two (or more) linguistic expressions that refer to discourse entities considered to be at the same granularity level relevant to the linguistic and pragmatic context. We view coreference relations in terms of mental space theory and discuss a large number of real life examples that show near-identity at different degrees.

Narrative discourse in interviews to linguistically mixed couples

This article deals with self-referential storytelling in sociolinguistic interviews. It analyzes the personal stories in ten interviews to linguistically heterogeneous couples. For this purpose, it is applied the model of linguistic analysis of drama (Bruner & Weisser 1991) and it identifies and interprets discursive markers of autobiographical storytelling. Therefore it takes into consideration the elements referred to agents and to their actions, to the sequences of events, to the canon or rule, and to the narrator's perspective. At the same time, it proposes to extend our approach to the existence itself of the participants. Resumen.-"Discurso narrativo en entrevistas a parejas lingüísticamente mixtas". Este artículo trata de las narraciones autorreferenciales en entrevistas sociolingüísticas sobre concepciones y usos de las lenguas en familias lingüísticamente mixtas. Analiza los relatos que aparecen en diez entrevistas a padres y madres que forman parejas lingüísticamente heterogéneas. Aplica el modelo de análisis lingüístico del dramatismo (Bruner & Weisser 1991). Identifica e interpreta los marcadores discursivos de la narración autobiográfica. Con este propósito considera los constituyentes que se refieren a los agentes y sus acciones, a las secuencias de sucesos, al canon o norma y a la perspectiva del narrador. Y propone la ampliación del estudio a los guiones de vida de lo actores. Palabras clave: entrevista, relato, narración, pareja, política lingüística de la familia, multilingüismo, marcador discursivo.

Qué puede aportar la educación bilingüe a la educación lingüística del Siglo XXI

This article is a reflection about the future which does not obviate all the knowledge acquired in nearly a hundred years time of research about bilingualism and bilingual education. In the first part, it considers the psycho-educational base where bilingualism lies on. In the second part, this article shows the possibilities and the limits of bilingual education in societies which are more and more diversified on linguistic terms. Finally, it reviews some of the guidelines about linguistic education both in Europe and in this country, while it points out some methods to promote the multilingual competence of students

Traditional cockney and popular London speech

This paper gives a full description of the phonetics and phonology of Traditional Cockney and Popular London speech, treating these varieties as constituting a continuum rather than two separate dialects. Exemplification of the vowels, diphthongs and consonants is provided, both in isolate words and in connected speech, along with their range of variation. The frequencies of the vowels have been charted on the basis of the pronunciation of three elderly male speakers. Regarding the consonants, there are detailed observations on the features typically associated with the linguistic varieties examined: strong aspiration of unvoiced plosives, glottalization, H-dropping, L-vocalization and TH-fronting. A section on prosody provides coverage of lexical stress, rhythm and intonation. The paper takes into account up-to-date research on these phenomena, but does not deal with the most recent vowel shifts, some of which form part of Multi-cultural London English.

The Tibidabo Treebank

En este artículo presentamos el desarrollo de un nuevo recurso de código abierto para el español: el treebank Tibidabo. La anotación se está llevando a cabo de forma semiautomática en la que, en primer lugar, el corpus es analizado automaticamente con una gramática simbólica del español basada en HPSG e implementada en el sistema Linguistic Knowledge Builder, y, en segundo lugar, los resultados del proceso de análisis se desambiguan manualmente. La existencia del treebank Tibidabo nos permitirá futuros trabajos de investigación para el desarrollo y evaluación de una arquitectura híbrida que combine métodos simbólicos y estadísticos para el PLN, así como investigaciones orientadas a la hibridización de técnicas de bajo y alto nivel para el PLN.

Students’ viewpoint on engineering subjects taught in English

The European Educational Institutions have the challenge and the commitment to enhance multilingual competence and teaching curricular subjects in a foreign language is seen as one of the most promising alternatives. In that context, professors teaching different engineering subjects at the School of Engineering of the UPC at Manresa (EPSEM) have been involved in projects aiming at analyzing the current linguistic situation and developing some on-line open access materials using CLIL as a strategy. They formed the u-Linguatech Research Group on Multilingual Communication in Science and Technology in order to provide such resources in an effective and efficient way. In this paper, we focus on students’ perception of the improvement of their multilingual competence throughout their Engineering degree, by means of subjects taught in English by non-native speakers. Data about the English level of current students are taken into account. We also describe the use of the above resources to improve the quality of subjects learning related to Chemical Engineering curricula.
