Concilier les données qualitatives et quantitatives: un défi pour les recherches en acquisition du langage

What is the role of qualitative data? How should mixed approaches be considered? Is it necessary to complement the quantitative approach by the qualitative approach (Maziére et al., 2010) or the opposite? How can these two approaches be combined in a Language Acquisition research? What are the possibilities of generalization that these approaches provide? Besides those necessary theoretical discussions, our starting point is a qualitative research on the acquisition of the plural morpheme in Brazilian Portuguese (BP) in children between 1 year 11 months old and 2 years 7 months old (Hilário, 2012), whose linguistic production is intrinsically connected to their dialogic aspect (Bakhtin & Vološinov, 1973) and to the interaction among interlocutors (Bruner, 2004; Vygotsky, 1986). In this research through the usage of a computational tool (CLAN) it is expected to have more visibility of the quantitative results even if they are in a qualitative approach. Although, it should be taken into account the fact that each approach can achieve valid and relevant results (Valsiner 2000), i.e., with any given method it is possible to reach a kind of generalization (statistical or analytical).

Nouvelles techniques radiologiques pour les patients insuffisants rénaux

Radiological investigations using gadolinium or intravenous iodinated contrast products are used cautiously in patients suffering from chronic kidney disease because of their risk of acute kidney injury and systemic nephrogenic fibrosis. In this article, we review several radiological alternatives that can be useful to obtain renal anatomical and/or functional information in this patient population. The basic principles, indications, and advantages and limitations of Doppler ultrasound with measurement of the resistance index, contrast-enhanced ultrasound, and a technique called BOLD-MRI (blood-oxygenation level dependent-MRI) are discussed.

L'expérience de Iéna démontre les avantages de la diversité végétale pour les prairies

A number of studies suggest that there could be a positive relationship between the productivity of a plant community and its floristic diversity. Besides, for grasslands, productivity is not the only desirable advantage. The Jena trials, constituting a large-scale and long-duration experiment, were set up to tackle these questions. In the plots of the Jena trials, the number of species varies from 1 to 60. Various sub-trials deal with the effects of the composition and the diversity of a pasture sward on its productivity, the diversity of certain organisms, and several ecological processes. The results from the first 6 years show clearly that there exist positive relationships between the number of species, the presence of legumes and/or the functional diversity on the one hand, and on the other the productivity, the resistance to encroachment by plants and to pathogenic fungi, and the cycles of nutrients. The positive effects of the floristic diversity on the processes at the scale of the eco-system are of importance to the agricultural production and to the general environmental impact.
