PURPOSE This study evaluates the extent to which bilingual children produce the same or overlapping responses on tasks assessing semantic skills in each of their languages and whether classification analysis based on monolingual or conceptual scoring can accurately classify the semantic development of typically developing (TD) bilingual children. METHOD In Study 1, 55 TD children (ages 4;0 [y...

INTRODUCTION Wetlands are ecologically as well as economically important systems due to their high productivity, their nutrient (re)cycling capacities, and their prominent contribution to global greenhouse gas emissions. Being on the transition between terrestrial and—aquatic ecosystems, wetlands are buffers for terrestrial run off thereby preventing eutrophication of inland as well as coastal ...

Methods A total of 500 children with JIA were included prospectively in a population based Nordic cohort study in 1997-2000. All patients had a recent diagnosis of JIA at inclusion. Not all centers were able to collect DNA from patients and at 8 year follow-up DNA was available from 217 patients. All eight categories of JIA were represented in the final cohort. Clinical data were collected long...
