Dyadic executive function effects in children's collaborative hypermedia learning
Publication date: April 2019Source: Learning and Instruction, Volume 60Author(s): Cindy Paans, Eliane Segers, Inge Molenaar, Ludo VerhoevenAbstractThe current study investigated the extent to which executive functions (EF) affect how prior knowledge predicts hypermedia learning outcomes in primary school children. Learning outcomes were: individual knowledge and transfer, and dyadic assignment quality. Eighty-seven same-sex dyads participated in a hypermedia WebQuest assignment about the heart and living a healthy lifestyle. EF measures were action control and attention control. Dyadic analyses were performed using actor-partner interdependence models with dyads distinguished by EF. Analyses showed that one's own pre-test predicted one's own and partner's post-test for both higher and lower EF dyad members. Furthermore, for dyad members with relative higher EF only, their own and partner's pre-test predicted transfer. Finally, the lower action control dyad member's pre-test and the higher attention control dyad member's pre-test predicted assignment quality. These results show the importance of EF and prior knowledge for deeper conceptual understanding in a collaborative learning setting.
In conclusion, BLU-5937 was selected as a drug candidate for the treatment of chronic cough due to its high potency and selectivity for P2X3 homotrimeric receptors, strong anti-tussive effects, excellent tolerability and predicted pharmacokinetic properties in humans.
ConclusionThe SOS presents nearly as good as the SOFA score, to predict mortality among sepsis patients admitted to the ICU. The early warning score is another, alternative tool to use for risk stratification and sepsis screening for ICU sepsis patients.
Conclusions: Echogenicity of a pleural effusion has a low specificity for identifying an underlying exudate, and the echogenic qualities of the fluid should not influence clinical decision-making.Respiration
MRC Laboratory of Molecular Biology researchers reveal atomic structures of the abnormal tau filaments associated with chronic traumatic encephalopathy, a head injury-associated neurodegenerative disease, differ in structure from those seen in Alzheimer’s disease.
ConclusionsThese findings indicate that the neural effects of AUD vary according to severity. Our results emphasize the utility of resting state fMRI as a neuroimaging biomarker for quantitative clinical evaluation of AUD.

Schild, Thomas Klockgether, Henning BoeckerAbstractMany studies have used functional magnetic resonance imaging to unravel the neuronal underpinnings of motor system abnormalities in Parkinson's disease, indicating functional inhibition at the level of basal ganglia-thalamo-cortical motor networks. The study aim was to extend the characterization of functional motor changes in Parkinson's Disease by dissociating between two phases of action (i.e. m...
ConclusionsA clinically relevant model of PTA of venous stenosis in mice was created. PTA-treated vessels had increased lumen vessel area and WSS. The alterations in tissue markers of vascular remodeling, tissue hypoxia, proliferation, and cell death may be implications for future design of drug and device development.
ConclusionWEB shape modification was observed in more than half of cases but with no influence regarding adequate occlusion rate. This quantitative approach of WSM highlights that this phenomenon appears to be early and progressive over time. This supports the hypothesis that WSM could be more probably related to aneurysm healing rather than external compression.
