Centre for Applied Linguistics at the University of Warwick

The Centre for Applied Linguistics was established in 1983 and has grown from a relatively small teaching unit to a large centre engaged in a wide variety of activities under the broad heading of Applied Linguistics. Our work includes English language teaching, teacher education, undergraduate and postgraduate teaching in applied linguistics, development of teaching and research resources, and small- and large-scale research

Motivación para aprender: un estudio internacional multinivel sobre la autonomía de los estudiantes y el énfasis de los docentes en la utilidad del contenido

Teacher autonomy support is related to improved student learning. In higher education, few studies relate classroom contextual factors, such as teacher emphasis on content usefulness, and students' motivational characteristics.  The aim was to test a multilevel model about the relation between the extent of teachers’ emphasis on the usefulness of class content with student autonomy, and, in turn, on motivation to learn. The participants were 3033 university students enrolled from 1st to 4th grade of Sciences of the Physical Activity and Sport, from universities in Spain (N = 602), Portugal (N = 469), Mexico (N = 1177), Chile (N = 372), and Brazil (N = 413). A multilevel structural equation model was performed, in which participants answered questions about the teacher's emphasis on the usefulness of class content, basic psychological need for autonomy, and motivation to learn. At the group and individual levels, the hypothesis is that the teacher's emphasis on the usefulness of class content predict the student autonomy, in turn, student autonomy predicts student motivation to learn. Results found at the group level and at the individual level the strength of teacher emphasis on class content predicted student autonomy; student autonomy predicted student motivation to learn.En la educación superior, pocos estudios relacionan factores contextuales en la clase, como el énfasis del profesor en la utilidad del contenido y las características motivacionales de los estudiantes.  El objetivo fue probar un modelo multinivel sobre la relación entre el énfasis del docente en la utilidad del contenido durante la clase, la autonomía de los estudiantes y, a su vez, la motivación para aprender. Participaron 3033 estudiantes universitarios matriculados de 1º a 4º grado de Ciencias de la Actividad Física y del Deporte, de universidades de España (N = 602), Portugal (N = 469), México (N = 1177), Chile (N = 372), y Brasil (N = 413). Se realizó un modelo de ecuaciones estructurales multinivel, en el que los participantes respondieron preguntas sobre el énfasis del profesor en la utilidad del contenido de la clase, la autonomía y la motivación para aprender. Se hipotetizó que el énfasis del profesor en la utilidad del contenido predecía la autonomía del estudiante que, por su vez, predecía la motivación para aprender. Los resultados, a nivel grupal e individual, indican que el énfasis del docente en la utilidad del contenido predijo la autonomía del estudiante, y la autonomía predijo la motivación para aprender

Noise-assisted energy transport in electrical oscillator networks with off-diagonal dynamical disorder

Noise is generally thought as detrimental for energy transport in coupled oscillator networks. However, it has been shown that for certain coherently evolving systems, the presence of noise can enhance, somehow unexpectedly, their transport efficiency; a phenomenon called environment-assisted quantum transport (ENAQT) or dephasing-assisted transport. Here, we report on the experimental observation of such effect in a network of coupled electrical oscillators. We demonstrate that by introducing stochastic fluctuations in one of the couplings of the network, a relative enhancement in the energy transport efficiency of 22.5 ± 3.6% can be observed.Peer ReviewedPostprint (published version

Artistas sobre outras obras

A revista Estúdio inaugura neste começo do seu sétimo ano de existência uma periodicidade mais exigente: publica-se agora com um ritmo trimestral. No número 12 da Estúdio tinha-se lançado o tema “Identidade”. A muito boa resposta que o tema suscitou levou-nos a desdobrar a publicação dos artigos selecionados em dois números consecutivos da revista. Assim tem-se no presente uma segunda identidade. Fala-se de variabilidade e de identidade, sendo uma condição da outra. Neste ponto é pertinente recorrer a Darwin, que dscreve este olhar dividido, no capítulo 5 de a origem das espécies, no capítulo intitulado “Leis da variação.” Aí Darwin interroga-se sobre a duplicidade disfórica entre um antepassado comum — sinal do idêntico — e os dois tipos de diferenciação: as diferenças antigas e tornadas mais ou menos permanentes, que ocorreram antes de mudanças climáticas ou ambientais, e as diferenças que florescem nas partes mais recentes dos corpos — os caracteres específicos. Na Estúdio não estudamos propriamente seres vivos, mas sim discursos. Mas como as espécies, há troços do discurso que antecedem as mudanças ambientais (por exemplo, idiomas, algumas regras gerais comportamento) e outros, específicos, que sucedem às mudanças ambientais e contextuais. Assim os artigos aqui reunidos dão testemunho de uma referencialidade comum, profunda, antiga, e ao mesmo tempo de uma diversidade discursiva, que corresponde às suas diferenças contextuais. A identidade engana os incautos: o que ela mostra é o que ela esconde. Escondido atrás de ti, estão os que te chamam, os que te interpelam, os que te preenchem o sentido. Este, pleno, parece formar-se no outro. Afinal, os indivíduos podem ser como as palavras: o seu significado depende de todas as outras ausentesinfo:eu-repo/semantics/publishedVersio

Cd34+ Stromal Cells/Telocytes in Normal and Pathological Skin

We studied CD34+ stromal cells/telocytes (CD34+SCs/TCs) in pathologic skin, after briefly examining them in normal conditions. We confirm previous studies by other authors in the normal dermis regarding CD34+SC/TC characteristics and distribution around vessels, nerves and cutaneous annexes, highlighting their practical absence in the papillary dermis and presence in the bulge region of perifollicular groups of very small CD34+ stromal cells. In non-tumoral skin pathology, we studied examples of the principal histologic patterns in which CD34+SCs/TCs have (1) a fundamental pathophysiological role, including (a) fibrosing/sclerosing diseases, such as systemic sclerosis, with loss of CD34+SCs/TCs and presence of stromal cells co-expressing CD34 and αSMA, and (b) metabolic degenerative processes, including basophilic degeneration of collagen, with stromal cells/telocytes in close association with degenerative fibrils, and cutaneous myxoid cysts with spindle-shaped, stellate and bulky vacuolated CD34+ stromal cells, and (2) a secondary reactive role, encompassing dermatitis—e.g., interface (erythema multiforme), acantholytic (pemphigus, Hailey–Hailey disease), lichenoid (lichen planus), subepidermal vesicular (bullous pemphigoid), psoriasiform (psoriasis), granulomatous (granuloma annulare)—vasculitis (leukocytoclastic and lymphocytic vasculitis), folliculitis, perifolliculitis and inflammation of the sweat and sebaceous glands (perifolliculitis and rosacea) and infectious dermatitis (verruca vulgaris). In skin tumor and tumor-like conditions, we studied examples of those in which CD34+ stromal cells are (1) the neoplastic component (dermatofibrosarcoma protuberans, sclerotic fibroma and solitary fibrous tumor), (2) a neoplastic component with varying presentation (fibroepithelial polyp and superficial myxofibrosarcoma) and (3) a reactive component in other tumor/tumor-like cell lines, such as those deriving from vessel periendothelial cells (myopericytoma), epithelial cells (trichoepithelioma, nevus sebaceous of Jadassohn and seborrheic keratosis), Merkel cells (Merkel cell carcinoma), melanocytes (dermal melanocytic nevi) and Schwann cells (neurofibroma and granular cell tumor)

Towards a generic multiagent model for decision support: Two case studies

Publisher Copyright: © Springer-Verlag Berlin Heidelberg 2004.This paper describes how agent and knowledge technology can be used to build advanced software systems that support operational decision-making in complex domains. In particular, we present an abstract architecture and design guidelines for agent-based decision support systems, illustrate its application to two real-world domains - road traffic and bus fleet management - and discuss the lessons learnt from this enterprise.Peer reviewe
