Addressing soil nutrient degradation and global warming requires novel solutions. Enhanced weathering using crushed basalt rock is a promising dual-action strategy that can enhance soil health and sequester carbon dioxide. This study examines the short-term effects of basalt amendment on spring oat (Avena sativa L.

- * Researchers measured lithium (Li) isotopes to study changes in weathering processes during the PETM, finding a notable negative excursion of ~3‰ in global seawater and local inputs.
- * The results suggest a dramatic rise in global erosion rates by 2 to 3 times, leading to a 50-60% increase in weathering, which ultimately contributed to enhanced carbon burial and climate stabilization.
There is increasing recognition of the value of consumer participation in advocacy and community activism. Among trauma survivors, finding a sense of purpose and a way to make meaning from the trauma experience has been termed "survivor mission," and may include a call to social action, involvement in social justice activities, or public speaking. The current study describes the development of a trauma-informed trauma-survivor speakers' bureau (CHATT) and presents quantitative and qualitative outcome findings.

Cross-sectional student surveys were conducted by mail at baseline and at posttest 3 years later. Hierarchical linear modeling was applied to examine multiple drinking outcomes, taking into account the nonindependence of students grouped in the same college.
View Article and Find Full Text PDFObjective: An 18-site randomized trial was conducted to determine the effectiveness of social norms marketing (SNM) campaigns in reducing college student drinking. The SNM campaigns are intended to correct misperceptions of subjective drinking norms and thereby drive down alcohol consumption.
Method: Institutions of higher education were randomly assigned to treatment and control groups.
