La fraseolog��a en la clase de lengua extranjera: ��misi��n imposible?

En este art��culo ofrecemos una perspectiva diferente del aprendizaje y la ense��anza de la fraseolog��a en clase de lengua extranjera (LE). Partiendo de la premisa sobre el car��cter eminentemente hol��stico del lenguaje, concebimos las unidades fraseol��gicas (UF) como elementos habituales e inherentes en la comunicaci��n verbal, por lo que no pueden excluirse del proceso de adquisici��n de la competencia comunicativa en una LE. Nuestra propuesta consiste en partir de la fraseolog��a para optimizar el desarrollo de diversas subcompetencias de la competencia comunicativa. Para ello, resulta imprescindible indagar en la configuraci��n y el funcionamiento del significado fraseol��gico, que, seg��n defendemos en este trabajo, conforma un conjunto de informaciones de diversa ��ndole que se articulan en dos niveles, el sem��ntico y el pragm��tico. Tal indagaci��n permite desarrollar una serie de consideraciones con interesantes implicaciones did��cticas.

Fraseodid��ctica: a fraseolox��a para a did��ctica

In this article it is offered a different view of the role of phraseology in the foreign language class. Considering the holistic nature of language, phraseological units are conceived as inherent elements in the verbal communication, which confirms its importance in the formation process of the communicative competence in a foreign language. With attention to the modular conceptions of the communicative competence (Canale 1983) and of the phraseological meaning (Timofeeva 2012), it is proposed conceiving the phraseology as a starting point for developing the different parts of communicative competence. As it is explained, phraseological meaning is conformed by several informational chunks articulated in two levels, the semantic and the pragmatic. The connexions between these chunks and the parts of communicative competence allow to use more effectively the phraseological contents for the foreign language learning and teaching.

A Quantile-Based Probabilistic Mean Value Theorem

For non-negative random variables with finite means we introduce an analogous of the equilibrium residual-lifetime distribution based on the quantile function. This allows us to construct new distributions with support (0, 1), and to obtain a new quantile-based version of the probabilistic generalization of Taylor's theorem. Similarly, for pairs of stochastically ordered random variables we come to a new quantile-based form of the probabilistic mean value theorem. The latter involves a distribution that generalizes the Lorenz curve. We investigate the special case of proportional quantile functions and apply the given results to various models based on classes of distributions and measures of risk theory. Motivated by some stochastic comparisons, we also introduce the ���expected reversed proportional shortfall order���, and a new characterization of random lifetimes involving the reversed hazard rate function.
