Teaching and learning discourse analysis: some ideas on the use of ICTs

[EN]ICTs have played a major role in transforming the way we teach and learn. The purpose of this paper is to present some ideas on how ICTs can be implemented in the teaching and learning of discourse analysis. ICTs offer valuable material to help explain key theoretical concepts of discourse analysis and to examine linguistic and social reality. A tweet, a video song, a speech, an advertisement or a hoax-mail may enhance students’ motivation and stimulate critical thinking.

Existence and uniqueness of positive and nondecreasing solutions for a class of singular fractional boundary value problems

[EN] We establish the existence and uniqueness of a positive and nondecreasing solution to a singular boundary value problem of a class of nonlinear fractional differential equation. Our analysis relies on a fixed point theorem in partially ordered sets.
