Estudiem en aquest article els primers passos en l'evolució semàntica i en la gramaticalització del verb "jaquir". Aquest germanisme pertany a un estrat lèxic del català que va començar a fer-se menys usual a la darreria del segle XV, desplaçat per altres sinònims, en aquest cas lleixar-deixar. La recerca es fonamenta en un corpus de documentació en llatí i en català dels segles XI i XII. L'objectiu és descriure la gènesi dels significats que ja apareixen ben establits durant el període literari. Seguim un enfocament metodològic d'orientació cognitivista (estudi de la subjectivació i de la inferència com a mecanismes del canvi semàntic).

L’estudi de la neologia és indestriable de l’estudi del canvi lingüístic i, doncs, de la diacronia. Ens proposem ací descriure el procés de canvi semàntic que va experimentar el verb esmar, forma patrimonial del llatí *adaestimare, paral·lela del cultisme estimar. Aquesta recerca es fonamenta en l’aprofitament dels corpus textuals i altres materials despullats manualment. Sobre aquests materials, s’ha assajat l’anàlisi de la subjectivació i de les inferències que proposa la teoria de la inferència invitada del canvi semàntic (= TIICS).

The reprise evidential conditional (REC) is nowadays not very usual in Catalan: it is restricted to journalistic language and to some very formal genres (such as academic or legal language), it is not present in spontaneous discourse. On the one hand, it has been described among the rather new modality values of the conditional. On the other, the normative tradition tended to reject it for being a gallicism, or to describe it as an unsuitable neologism. Thanks to the extraction from text corpora, we surprisingly find this REC in Catalan from the beginning of the fourteenth century to the contemporary age, with semantic and pragmatic nuances and different evidence of grammaticalization. Due to the current interest in evidentiality, the REC has been widely studied in French, Italian and Portuguese, focusing mainly on its contemporary uses and not so intensively on the diachronic process that could explain the origin of this value. In line with this research, that we initiated studying the epistemic and evidential future in Catalan, our aim is to describe: a) the pragmatic context that could have been the initial point of the REC in the thirteenth century, before we find indisputable attestations of this use; b) the path of semantic change followed by the conditional from a ‘future in the past’ tense to the acquisition of epistemic and evidential values; and c) the role played by invited inferences, subjectification and intersubjectification in this change.

El objetivo de este estudio es analizar las actitudes de los futuros docentes hacia los recursos tecnológicos en el aula. Hemos considerado tres dimensiones de análisis: la práctica en las aulas, el aprendizaje del alumnado y la valoración que los futuros docentes hacen de su propia actitud frente a los recursos tecnológicos. Para el análisis estadístico se han utilizado técnicas descriptivas; la prueba t para la comparativa de grupos independientes, y el análisis univariado de covarianza (ANOVA). Los resultados indican que la actitud es positiva, aunque podemos comprobar que existen algunas diferencias significativas en cuanto a género respecto a algunas de las cuestiones planteadas.

A partir del problema de l'alimentació inadequada que segueix bona part de la població i les conseqüències que comporta en termes de salut (Varela, coord., 2013) s'aborda l'alternativa gastronòmica que representa el model alimentari de la Dieta Mediterrània (DM) per a fer front a molt d'aquests problemes, com també el paper que pot jugar l'etnobotànica en el procés de readaptació d'aquell model a la realitat del segle XXI i a la configuració d'una cultura aliffientària saludable i sostenible.

This study analyzes the process of semantic change by which the Old Catalan verb sentir developed from a meaning based on general perception to one implying auditory perception. In particular, the article shows that by the end of the 13th century the verb sentir had only semanticized the perception of non-linguistic auditory stimuli and had not fused completely with the meaning of the verb oir, as was the case with the evolution of SĔNTĪRE in other Romance languages (such as Peninsular Spanish). Our study has been based on data analysis of an electronic linguistic corpus using the concepts of E. C. Traugott’s Invited Inferencing Theory of Semantic Change (IITSC) (2012) and the concept of evidentiality.
