Lessons in a Green School Environment and in the Classroom: Effects on Students' Cognitive Functioning and Affect.

The positive impact of short-term exposure to nature during a green recess in a school day is documented in the literature. In this study we investigated cognitive, academic, and affective effects of a single contact with nature during a regular school lesson in the greenness, compared to an usual classroom lesson, on young students in second and third grades (N = 65). In a within-subjects design, for the cognitive effects we examined children's (a) selective and sustained attention and (b) math calculation performance in common school tasks.

Do medium and Context Matter when learning from multiple complementary Digital texts and videos?

Unlabelled: Students more than ever learn from online sources, such as digital texts or videos. Little research has compared processes and outcomes across these two mediums. Using a between-participants experimental design, this study investigated whether medium (texts vs.

Air-Processed Infrared-Annealed Printed Methylammonium-Free Perovskite Solar Cells and Modules Incorporating Potassium-Doped Graphene Oxide as an Interlayer.

The use of solution processes to fabricate perovskite solar cells (PSCs) represents a winning strategy to reduce capital expenditure, increase the throughput, and allow for process flexibility needed to adapt PVs to new applications. However, the typical fabrication process for PSC development to date is performed in an inert atmosphere (nitrogen), usually in a glovebox, hampering the industrial scale-up. In this work, we demonstrate, for the first time, the use of double-cation perovskite (forsaking the unstable methylammonium (MA) cation) processed in ambient air by employing potassium-doped graphene oxide (GO-K) as an interlayer, between the mesoporous TiO and the perovskite layer and using infrared annealing (IRA).

Impact of regional copayment policy on selective serotonin reuptake inhibitor (SSRI) consumption and expenditure in Italy.

Purpose: The continuous growth of antidepressant consumption and expenditure, especially for selective serotonin reuptake inhibitors (SSRIs), has led to the adoption of several policy measures directed toward cost control in Western countries. In Italy, copayment policies have been heterogeneously introduced at a regional level as part of a strategy designed to reduce drug consumption. The aim of our study was to evaluate whether regional copayment policies have affected trends in the consumption of and expenditure for SSRIs from 2001 to 2007.
