The increasing global demand for biofuels will require conversion of conventional agricultural or natural ecosystems. Expanding biofuel production into areas now used for agriculture reduces the need to clear natural ecosystems, leading to indirect climate benefits through reduced greenhouse-gas emissions and faster payback of carbon debts. Biofuel expansion may also cause direct, local climate changes by altering surface albedo and evapotranspiration, but these effects have been poorly documented. Here we quantify the direct climate effects of sugar-cane expansion in the Brazilian Cerrado, on the basis of maps of recent sugar-cane expansion and natural-vegetation clearance combined with remotely sensed temperature, albedo and evapotranspiration over a 1.9 million km2 area. On a regional basis for clear-sky daytime conditions, conversion of natural vegetation to a crop/pasture mosaic warms the cerrado by an average of 1.55 (1.45-1.65) °C, but subsequent conversion of that mosaic to sugar cane cools the region by an average of 0.93 (0.78-1.07) °C, resulting in a mean net increase of 0.6 °C. Our results indicate that expanding sugar cane into existing crop and pasture land has a direct local cooling effect that reinforces the indirect climate benefits of this land-use option.

Erik Olin Wright is a professor in the Department of Sociology, University of Wisconsin - Madison. His extensive writings on class analysis provide a perspective that seems more useful for structural class analysis in North America. He   incorporates analysis of recent developments in capitalism in this class analysis. Wright's work is within the Marxian and critical tradition, is theoretical, historical and quantitative, builds on earlier Marxian approaches to the study of social class, and also introduces ideas and approaches reminiscent of Max Weber and other writers. Wright's analysis is not only theoretical but is also heavily empirical - examining organization of jobs and enterprises along with views and characteristics of individuals in the labour force.  The work of Wright is contained in Class, Crisis and the State (1978), Class Structure and Income Determination (1979), and Classes (1985), and Class Counts (1997).

The recent uprisings in North Africa and the Middle East represent one of the most dramatic global political developments since the fall of the Berlin Wall.  What factors and forces led to the sudden collapse of well-entrenched regimes and the emergence of democratic reform movements across a region long accustomed to hereditary succession and autocratic rule?  Does the current upheaval reflect unique circumstances in the Arab World?  Or should it be viewed in the wider context of governance issues and challenges that have arisen in Asian and other settings beyond North Africa and the Middle East?  As a governance specialist whose international career has spanned Arab and Asian societies, David Arnold will share his insights regarding these questions.  

David D. Arnold became the president of The Asia Foundation on January 1, 2011, after serving as the president of the American University in Cairo (AUC) for seven years. At AUC he superintended the construction of a new, state-of-the-art $400 million campus, including the region's largest English-language library; spearheaded a $125 million fundraising campaign, the largest in the University's history; and oversaw academic innovations including AUC’s first-ever PhD program and master’s programs in education, biotechnology, gender studies, digital journalism, and refugee studies.  Under his leadership, AUC also expanded its continuing education and community outreach activities and created new scholarship opportunities for its students.  Mr. Arnold’s earlier career included six years as executive vice president of the Institute of International Education and more than ten years of service in the Ford Foundation including stints in India, Nepal, and Sri Lanka.  He earned his Master’s in Public Administration at Michigan State University following a BA from the University of Michigan.

Steven J. Zipperstein is the Daniel E. Koshland Professor in Jewish Culture and History at Stanford University. He has also taught at universities in Russia, Poland, France, and Israel; for six years he taught Jewish history at Oxford University. From 1991-2007, he was Director of the Taube Center for Jewish Studies at Stanford. Zipperstein is the author and editor of nine books including The Jews of Odessa: A Cultural History (1986, winner of the Smilen Prize for the Outstanding book in Jewish history); Elusive Prophet: Ahad Ha’am and the Origins of Zionism (1993, winner of the National Jewish Book Award); Imagining Russian Jewry (1999); and Rosenfeld’s Lives: Fame, Oblivion, and the Furies of Writing (2008, shortlisted for the National Jewish Book Award in Biography, Autobiography and Memoir).  His work has been translated into Russian, Hebrew, and French. Zipperstein’s latest book, Pogrom:  Kishinev and the Tilt of History, published by Liveright/W. W. Norton in 2018, has been widely reviewed in newspapers and magazines in the United States and England including The New York Times, New York Review of Books, The New Yorker, The New Statesman, Literary Review, and the San Francisco Chronicle. The Economist, Ha-Aretz, San Francisco Chronicle and Mosaic Magazine have named it one of the best books of the year.  It was a finalist for the National Jewish Book Award (History) and Mark Lynton award for the best non-fiction book of 2018. 

He has been awarded the Leviant Prize of the Modern Language Association, the Judah Magnes Gold Medal of the American Friends of the Hebrew University, and the Koret Prize for Outstanding Contributions to the American Jewish community.  He has held fellowships at the Radcliffe Institute at Harvard University, the Institute for Advanced Studies at the Hebrew University of Jerusalem, the Yitzhak Rabin Institute in Tel Aviv, and has twice been a Visiting Professor at the Ecole des Hautes Etudes Sciences Sociales.  In spring 2014, he was the first Jacob Kronhill Scholar at the YIVO Institute for Jewish Research, in New York. At Stanford, and earlier at Oxford and UCLA, he has supervised the dissertation work of more than thirty students now teaching at universities and colleges in the United States, Canada, and elsewhere.  He has delivered keynote addresses and endowed lectures at several dozen universities in the United States and abroad including the Hebrew University, Jerusalem; Central European University, Budapest; Emory; UCLA; University of Wisconsin, Madison; Vanderbilt, and the National Yiddish Book Center. 

Zipperstein’s articles have appeared in The New York Times Sunday Book Review, the Washington Post, The New Republic, the Jewish Review of Books, Chronicle of Higher Education and in many scholarly journals.  He was an editor of Jewish Social Studies for twenty years, and the book series Stanford Studies in Jewish History and Culture for a quarter of a century.  He is immediate past Chair of the Academic Council of the Center for Jewish History, in New York. Together with Anita Shapira, he is series editor of the Yale University Press/Leon Black Foundation Jewish Lives volumes that were named in 2015 the best books of the year by the National Jewish Book Council -- the first time a book series has won this prize. Some forty-five Jewish Lives books have already appeared, and Zipperstein is currently at work on a biography of Philip Roth for the series.  He and his wife Susan Berrin live in Berkeley.
