Aminoallenylidene complexes of ruthenium(II) from the regioselective addition of secondary amines to butatrienylidene intermediates: a combined exper…
2003
Aminoallenylidene complexes trans-[Cl(dppm)2RuC3(NRR )(CH3)] are obtained from the regioselective addition of secondary amines to trans-[Cl(dppm)2Ru C C C CH2] . Unsymmetrically substituted amines give rise to Z/E isomeric mixtures. Dynamic 31P NMR spectroscopy gave an energy barrier of about 85 kJ mol 1 for rotation around the CN-bond pointing to a large contribution of the iminium alkynyl resonance form trans-[Cl(dppm)2Ru–C C– C( NRR )(CH3)] . This is also indicated by the pronounced bond length alternation within the RuC3N-chain as is revealed by X-ray structure analysis of the Z isomer of the (benzylmethyl)methylamine derivative 2d. The issue of NR2 rotation was also addressed by DFT ca…
Linear dynamics induced by odometers
2022
Weighted shifts are an important concrete class of operators in linear dynamics. In particular, they are an essential tool in distinguishing variety dynamical properties. Recently, a systematic study of dynamical properties of composition operators on $L^p$ spaces has been initiated. This class of operators includes weighted shifts and also allows flexibility in construction of other concrete examples. In this article, we study one such concrete class of operators, namely composition operators induced by measures on odometers. In particular, we study measures on odometers which induce mixing and transitive linear operators on $L^p$ spaces.
De nuevo sobre la intensificación pragmática : revisión y propuesta
2021
Este artículo presenta una propuesta de caracterización de la intensificación desde una perspectiva pragmática con el objetivo de contribuir al establecimiento de una definición completa, delimitada y unitaria del fenómeno, que permita reconocer y discriminar los usos intensificaciones de otras categorías cercanas. Para ello, se revisan las principales aportaciones previas al estudio del fenómeno: desde las más extendidas, de carácter gramatical y semántico, a las más recientes de naturaleza pragmática.
 Se propone, por un lado, una explicación cognitiva y metarrepresentacional que define la intensificación como el intento lingüístico de un hablante por modificar los supuestos que le a…
De M. Bergeret a D. Toni de Bearn: Llorenç Villalonga, ironista
2012
El present article investiga la importància de la ironia en la producció literària de Llorenç Villalonga. En primer lloc analitza l’ús de la ironia en l’escriptor francès Anatole France, mestre admirat de Villalonga, i de manera particular en el seu personatge Lucien Bergeret, la màxima creació de l’autor. En segon lloc estudia la concepció de la ironia en Villalonga i del seu ús a la seua novel·la Bearn o la sala de les nines, amb una atenció especial al seu protagonista, l’ eiron D. Toni de Bearn, personatge íntimament relacionat amb el professor Bergeret francià, i als models novel·lístics de la novel·la de tesi i de la novel·la d’aprenentatge o de formació. This paper is devoted to stud…
Escuela y diversidad lingüística: estudio de las actitudes lingüísticas de los futuros docentes valencianos
2019
The article analyses the linguistic attitudes of future Valencian teachers in a bilingual speaking community characterised by mainstream contact between the Catalan and Spanish languages. This research focuses on the language attitudes of a group of speakers who share a specific set of traits: age, education, profession and socioeconomic status. Special attention is given to attitudes towards four linguistic varieties used by Valencian speakers in their regular interactions: standard Spanish (CS), colloquial Spanish – nonstandard – (CNS), standard Valencian (VS) and vernacular Valencian or apitxat (VNS).
Hibridisme i autoreferència en el fantàstic d'Espiral, de Manuel Baixauli
2018
The aim of this paper is to define and to analyse the fantastic universe of short stories by Manuel Baixauli published in the volume Espiral (2010), an original and highly significant example of modern fantastic literature that has abolished the real and imaginary borders, that is to say a significant example of fantastic literature conceived as a language phenomenon. The conception of reality integrates and naturalises the supernatural and the irrational in a vision that joins multiple dimensions and perspectives of reality. The self-referential component is also of essential importance in this fantastic, which assimilates and exhibits themes and motifs of inherited traditions in a fully c…
Literatura y cultura para una didáctica intercultural del español como lengua extranjera (ELE)
2016
This work evolves around a main purpose: to analyze the role of literature in the pedagogy of Spanish as a Foreign Language from an intercultural perspective. From this standpoint, we reflect about the importance of the term Spanish Literature to defend the different literatures implied in the syntagm; hence, we study how comparative literature becomes the main tool to understand linguistic, cultural and literary diversity. We consider that these two ideas should be in the pedagogical profile of the Spanish as a Foreign Language professor.
Learners’ identifies at stake: Digital identity texts in the ELF classroom
2018
Author/s María Dolores García-Pastor GIEL – Universitat de València, Spain ABSTRACT This paper focuses on the study of identity in digital identity texts produced by English as a foreign language (EFL) learners within a specific subject of the Teacher in Primary Education (English) degree at a Spanish university. To this end, 51 digital identity texts were analysed following a “positioning perspective”, which views identity in terms of “reflexive” and “interactive” positions (Davies & Harré 1990). Results show that learners constructed non-unitary identities whose subject positions were often contradictory. They also associated certain positions with silencing identities, transition ident…
Encapsulació i estructura informativa en el debat parlamentari. Una anàlisi contrastiva (català – espanyol – anglès)
2016
Parliamentary debate (PD) as a specific genre of parliamentary discourse exhibits a hybrid nature: part oral and part written discourse. It is performed orally, but planned ahead and formal. From the point of view of lexical cohesion, encapsulation by means of abstract and unspecific nouns (e.g. factor reason) is an indicator of the informative density and the underlying written natureof PD.With the tools provided by Discourse Analysis and Cognitive Linguistics, this paper aims at describing and characterizing cross-linguistically lexical encapsulation’s potential to define the information struc-ture of PD. In this regard, encapsulation is analyzed in relation to the notions of topic and fo…
De l’infinitive de perception dans la pratique traductologique
2019
Nous prenons pour objet d’etude l’Infinitive de Compte rendu de Perception (ICP), cette construction infinitive qui, regie par un verbe de perception comme "voir", "regarder", "entendre", "ecouter" ou "sentir", se compose a la fois d’un syntagme nominal et d’un verbe a l’infinitif completifs ("j’entends "les oiseaux" "chanter""). Le cadre dans lequel nous nous interesserons ici a l’ICP est celui de la traduction, en l’occurrence du francais vers le polonais. Cette structure, si commune en francais, n’existant pas en polonais, en effet, la langue slave ne compte pas moins de huit traductions differentes effectives (c’est-a-dire observables dans les corpus), dont la plus frequente s’avere la …
