Publication The library of Daniel Garrison Brinton(University of Pennsylvania. Museum of Archaeology and Anthropology.) Weeks; Weeks, John M.This book includes an introductory essay and item-by-item catalog for the personal library of Daniel Garrison Brinton. First a professor of Ethnology and Anthropology at the Academy of Natural Sciences, then later Penn’s first Professor of Archaeology and Linguistics, Brinton (1837-1899) is considered one of the fathers of American anthropology. He built a substantial personal library of over 4000 items, mainly focused on the languages and culture of indigenous peoples of North and Central America. It included several early-modern manuscripts, modern transcriptions, and early printed books from the estate of ethnologist and linguistic scholar, Carl Hermann Berendt (1817-1878), and from the Mayanist, Charles Etienne Brasseur de Bourbourg (1814-1874). After his death, Brinton’s library passed to the Penn Museum for the creation of the Penn Museum Library in 1900.Publication Exploring Hydrophobic and Lipophilic Properties of Magic Sand: Implications for Oil Spill Cleanup(Singh Center for Nanotechnology) Unger, Gabriel; Song, Ethan; Kim, GyuseokIn this study, we investigate the hydrophobic and lipophilic properties of magic sand by examining the behavior of water and oil droplets on magic sand surfaces. The contact angle between water and magic sand exceeds 120 degrees, indicating hydrophobic behavior, while the contact angle between oil and magic sand is significantly less than 90 degrees, suggesting lipophilic characteristics. To establish a comparative analysis, we performed similar tests using regular sand, demonstrating hydrophilic and lipophilic properties with contact angles against water and oil of less than 90 degrees. Leveraging these divergent properties, we conducted a simulated oil spill cleanup employing magic sand, resulting in a notable reduction of oil levels in water as the magic sand readily absorbed and sank with the oil.Publication MOOCS in Higher Education: Institutional Goals and Paths Forward(2015-01-01) Hollands, Fiona M; Tirthali, DevayaniIn 2011, MOOCs dominated media reports on higher education and, since then, hundreds of organizations have rushed to produce and offer these courses. Why are institutions offering MOOCs and what are they achieving as a result? This book addresses these questions based on interviews with almost one hundred educators, policy makers, and business people. Hollands and Tirthali identify six major goals for MOOC production and, using real-life examples, assess whether these goals are being achieved and, if not, how they could be accomplished going forward.Publication Cost-Effectiveness and Educational Policy(2002-01-01) Levin, Henry M; McEwan, Patrick JThis Yearbook of the American Educational Finance Association provides methodological treatments of cost-effectiveness in education as well as specific studies using the method.Publication The Price We Pay(2007-01-01) Belfield, Clive R; Levin, Henry MThis volume addresses the economic consequences of the failure to adequately educate vast numbers of students. It represents an edited version of the contributions on costs of different approaches to reducing high school dropouts and the benefits in labor markets, earnings, tax revenues, and reduced costs of public health, criminal justice, and public assistance. Empirical estimates are provided for both benefits and costs.
