At head of title: The National Academies Keck Futures Initiative.

"In November 2020, the National Academies of Sciences, Engineering, and Medicine convened a multi-day virtual symposium on imaging the future of undergraduate STEM education. Speakers and participants pondered the future and the past and shared their goals, priorities, and dreams for improving undergraduate STEM education. Expert speakers presented information about today's students and approaches to undergraduate STEM education, as well as the history of transformation in higher education. Thoughtful discussions explored ideas for the future, how student-centered learning experiences could be created, and what issues to consider to facilitate a successful transformation. This publication summarizes the presentation and discussion of the symposium."--

Based on a workshop held March 17, 2008 in Washington, DC.

Extremely hazardous substances (EHSs), as defined in the Superfund Amendments and Reauthorization Act of 1986, can be released accidentally as a result of chemical spills, industrial explosions, fires, or accidents involving railroad cars or trucks used in transporting these substances, or intentionally through terrorist activities. It is also feasible that these substance can be released by improper storage and/or handling. Workers and residents in communities surrounding industrial facilities where EHSs are manufactured, used, or stored and in communities along the nation's railways and highways are potentially at risk of being exposed to airborne EHSs during accidental and intentional releases. This report provides technical guidance on establishing community Acute Exposure Guideline Levels (AEGLs) for certain hazardous chemicals. It reviews the scientific validity of AEGLs developed by the national Advisory Committee on Acute Exposure Guideline Levels for Hazardous Substances, identifies research priorities, and identifies guidance issues that may require modification or further development based on the toxicological database for the chemicals reviewed. This twelfth interim report offers recommendations for improving AEGLs for the following 15 chemicals: toluene, xylenes, ammonia, bromine, aniline, methyl ethyl ketone, hydrazine, iron pentacarbonyl, phosphine, chlorine, trifluoride, ethyleneimine, propyleneimine, allyl alcohol, ethylene oxide, and nickel carbonyl.

This book explores in detail threats to the world's sea turtle population to provide sound, scientific conclusions on which dangers are greatest and how they can be addressed most effectively. Offering a fascinating and informative overview of five sea turtle species, the volume discusses sea turtles' feeding habits, preferred nesting areas, and migration routes; examines their status in U.S. waters; and cites examples of conservation measures under way and under consideration.
