"The aim of this study is to examine the impact of charter schools on student achievement in the Great Lakes states: Illinois, Indiana, Michigan, Minnesota, Ohio, and Wisconsin. This evaluation addresses two specific questions: How does student achievement in charter schools compare with student achievement in demographically similar, traditional public schools? Do charter schools show promise of being an effective strategy for improving student achievement over time, even if they are not yet outperforming traditional public schools?"--Page 1
This 2-year project used a ground-based laser scanner to map avalanche path snow depths to support an effectiveness assessment of recently-installed Gazex avalanche control systems in the Loveland Pass (Seven Sisters) and Berthoud Pass (Stanley) highway corridors. Scans were collected during snow-free conditions for a baseline, and then prior to and post-storm event and post control operations, as weather and logistics allowed. Snow depth and snow depth change maps were derived from the laser scans, informing an assessment of specific controlled avalanche events and the general performance of the Gazex exploders in the individual starting zones.
