More evidence concerning the aspect hypothesis: The acquisition of English progressive aspect by Catalan-Spanish instructed learners

A robust finding of studies investigating the Aspect Hypothesis is that learners at early stages of acquisition show a strong preference for using the progressive aspect as associated with activity verbs. As they advance in their acquisition of the second or foreign language, learners move from this prototypical association to associations traditionally considered to be more peripheral (e.g.-ing with accomplishments or achievements). Within this framework, the goal of this paper is to provide further evidence from groups of learners with different proficiency levels with regard to the acquisition of progressive aspect by tutored learners of English who are bilingual Catalan-Spanish. This is done by eliciting data by means of two different task types and by looking at both tokens and types. Our results are consistent with previous research according to which-ing morphology is closely associated with durative lexical aspect, although not necessarily with activity predicates. The study also shows that the type of task has an influence on the frequency and the distribution of learners" progressive forms.

Erreurs innées du métabolisme: transition enfant-adulte [Inborn errors of metabolism: transition from childhood to adulthood].

Les erreurs innées du métabolisme (EIM) sont dues à des mutations de gènes codant pour des enzymes du métabolisme et sont classées selon trois grands groupes de maladies: 1) intoxications; 2) déficit énergétique et 3) déficit de synthèse ou catabolisme des maladies complexes. Le progrès thérapeutique des vingt dernières années a permis d'améliorer le pronostic des enfants atteints d'EIM. Ces enfants grandissent et doivent être pris en charge à l'adolescence et à l'âge adulte par des équipes spécialisées. Cette médecine métabolique pour adultes est une discipline relativement nouvelle avec une information limitée chez l'adulte. Les recommandations pédiatriques sont extrapolées à la prise en charge des adultes tout en intégrant les différentes étapes de vie (indépendance sociale, grossesse, vieillissement et éventuelles complications tardives). Inborn errors of metabolism (IEM) are due to mutations of genes coding for enzymes of intermediary metabolism and are classified into 3 broad categories: 1) intoxication, 2) energy defect and 3) cellular organelles synthesis or catabolism defect. Improvements of therapy over these last 20 years has improved prognosis of children with IEM. These children grow up and should have their transition to specialized adult care. Adult patients with IEM are a relatively new phenomenon with currently only limited knowledge. Extrapolated pediatric guidelines are applied to the adult population taking into account adult life stages (social independence, pregnancy, aging process and potential long-term complications).
