- Comptes rendusPublication . Conceição, Manuel Célio; Humbley, JohnLa réflexion sur les procédés et les formes de dénomination des savoirs, sur les rapports entre les processus cognitifs et leurs verbalisations (linguistiques et discursives) a reçu, lors des dernières décennies du XXe siècle, un essor particulier. N’étant pasun sujet vraiment nouveau, la terminologie a voulu s’armer d’un triple point de vue : épistémologique, théorique et pratique.
- Language policies and internationalization of higher educationPublication . Conceição, Manuel CélioIn the context of education for the global world, internationalization is a strategy and a goal of higher education (HE). In many cases, the conditions for carrying out internationalization are neglected in detriment of its economic and financial impact. The definition of appropriate language policies and their relation to the organization and functioning of institutions at all levels (teaching, research, transfer, governance, etc.) are constitutive aspects of internationalization. This definition considers the need to promote mobility and inclusion of different actors in HE and the need for competitive affirmation at local, national and international levels. Not only the conception of language policies must be clear, but the concept of language must be revisited within its relation to acquisition, construction and dissemination of knowledge in an ecological perspective of multilingual practices in HE, emphasizing that there is no science without languages and without linguistic diversity. In a contextually anchored complexity management framework, the relationship between language policies (or lack thereof) and pedagogical and methodological innovations is referred. This text emphasizes that language policies are essential in internationalization of HE. To achieve this purpose, a new concept of language and an integrated approach of language and knowledge/science are needed.
- Propositional density: cognitive impairment and agingPublication . Harrag, Chaimae; Sabil, Abdelkader; Conceição, Manuel Célio; Radvansky, Gabriel A.It is important to understand the relationship between cognitive abilities and language processing. Here, we explore a burgeoning area of research that harnesses semantic indices to predict cognitive impairment and track cognitive decline. One such index, propositional density, quantifies the information conveyed per language segment. Despite some variation stemming from methodological, sampling, and measurement differences, we suggest that propositional density has diagnostic and assessment value. This paper surveys existing studies that have used propositional density in the context of cognitive aging and impairment and offers some insights into the use of this index to highlight differences in cognition. We also suggest further explorations of basic research involving this concept, and some applications for assessing cognitive health.
