Summer Melt

Release Date: 2020-01-15
Under increasing pressure to raise graduation rates and ensure that students leave high school college- and career-ready, many school and district leaders may believe that, when students graduate with college acceptances in hand, their work is done. But as Benjamin L. Castleman and Lindsay C. Page show, summer can be a time of significant attrition among college-intending seniors—especially those from low-income families. Anywhere from 10 to 40 percent of students presumed to be headed to college fail to matriculate at any postsecondary institution in the fall following high school. Summer Melt explores the complex factors that contribute to this trend—the absence of school support, confusion over paperwork, lack of parental guidance, and the teenage tendency to procrastinate. The authors draw on findings from fields such as neuroscience, behavioral economics, and social psychology to contextualize these factors. Drawing on a series of research studies, they show how schools and districts can develop effective, low-cost, scalable responses—including counselor outreach, peer mentoring, and using text messages and social media—to help students stay on track over the summer. Summer Melt offers very practical guidance for schools and districts committed to helping their students make the transition to college.
Melt Water Retention Processes in Snow and Firn on Ice Sheets and Glaciers: Observations and Modeling
Melt takes place where the surface of glaciers or ice sheets interacts with the atmosphere. While the processes governing surface melt are fairly well understood, the pathways of the meltwater, from its origin to the moment it leaves a glacier system, remain enigmatic. It is not even guaranteed that meltwater leaves a glacier or ice sheet. On Greenland, for example, only slightly more than 50% of the meltwater runs off. The remainder mostly refreezes within the so-called firn cover of the ice sheet. This eBook contains 11 studies which tackle the challenge of understanding meltwater retention in snow and firn from various angles. The studies focus both on mountain glaciers and on the Greenland ice sheet and address challenges such as measuring firn properties, quantifying their influence on meltwater retention, modelling firn processes and meltwater refreezing as well as unravelling the mechanisms within the recently discovered Greenland firn aquifers.
Advances in Quantitative Ethnography
This book constitutes the refereed proceedings of the First International Conference on Quantitative Ethnography, ICQE 2019, held in Madison, Wisconsin, USA, in October 2019. It consists of 23 full and 9 short carefully reviewed papers selected from 52 submissions. The contributions come from a diverse range of fields and perspectives, including learning analytics, history, and systems engineering, all attempting to understand the breadth of human behavior using quantitative ethnographic approaches.
