Like many distributed systems, both natural and engineered, ant colonies operate without any central control. No ant can assess what needs to be done. Each ant responds to its interactions with other ants nearby and in the aggregate, these dynamical networks of interaction regulate colony behavior. Ecological studies show how collective organization evolves to respond to local, changing conditions. Harvester ant colonies living in the desert in Arizona use a simple positive feedback system, without any spatial information, to adjust foraging activity to the food supply. The rate at which foragers return to the nest with food determines the rate at which outgoing foragers leave the nest to search for more food.Turtle ant colonies living in the tropical forest in Mexico use interactions at temporary nest sites to regulate the shape and stability of the circuit of ants travelling through the trees. The talk will discuss models based on analogies between these systems and other dynamical networks, including the internet and brains. Exploring these analogies helps to elucidate how collective behavior evolves, shaping distributed algorithms in relation to changing environments.

Deborah M Gordon is a Professor in the Department of Biology at Stanford. She studies the evolution of collective organization by investigating the ecology and behavior of ant colonies. Her work includes the long-term demography and behavior of harvester ant colonies in Arizona; the factors that determine the spread of the invasive Argentine ant in northern California; and the ecology of ant-plant mutualisms in tropical forests in Central America. She is the author of two books, Ants at Work (2000) and Ant Encounters:Interaction Networks and Colony Behavior (2010). She has been awarded fellowships from Guggenheim and the Center for Advanced Study in Behavioral Sciences. She is interested in analogies between ant colonies and other distributed networks such as brains, the immune system, the internet, and distributed robotic systems.

This study quantifies worldwide health effects of the Fukushima Daiichi nuclear accident on 11 March 2011. Effects are quantified with a 3-D global atmospheric model driven by emission estimates and evaluated against daily worldwide Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) measurements and observed deposition rates. Inhalation exposure, ground-level external exposure, and atmospheric external exposure pathways of radioactive iodine-131, cesium-137, and cesium-134 released from Fukushima are accounted for using a linear no-threshold (LNT) model of human exposure. Exposure due to ingestion of contaminated food and water is estimated by extrapolation. We estimate an additional 130 (15–1100) cancer-related mortalities and 180 (24–1800) cancer-related morbidities incorporating uncertainties associated with the exposure–dose and dose–response models used in the study. Sensitivities to emission rates, gas to particulate I-131 partitioning, and the mandatory evacuation radius around the plant may increase upper bound mortalities and morbidities to 1300 and 2500, respectively. Radiation exposure to workers at the plant is projected to result in 2 to 12 morbidities. An additional 600 mortalities have been reported due to mandatory evacuations. A hypothetical accident at the Diablo Canyon Power Plant in California, USA with identical emissions to Fukushima may cause 25% more mortalities than Fukushima despite California having one fourth the local population density, due to differing meteorological conditions.

About the Topic: The Tiananmen Square massacre of June 1989 remains a taboo topic in the People’s Republic of China (PRC); the ruling Chinese Communist Party (CCP) still detains participants and suppresses online, popular, and scholarly discussions of it.  The twentieth anniversary of the end of the transatlantic Cold War, however, saw the release of new sources from high-level contacts between the CCP and foreign leaders. These new sources, combined with older ones, show the extent to which Chinese political leaders were obsessed with the democratic changes in Eastern Europe and were willing to take violent action to prevent similar events on their territory.

About the Speaker: Mary Sarotte is professor of history and professor of international relations at the University of Southern California. Her most recent book, 1989: The Struggle to Create Post-Cold War Europe, was called a new "classic" by Foreign Affairs and selected as a Book of the Year by the Financial Times. It received the DAAD Prize for Distinguished Scholarship in German and European Studies and became the first book to win both the Ferrell Prize for the best book on US foreign policy and the Shulman Prize for the best book on Communist foreign policy. Professor Sarotte received her PhD in History from Yale. She has been a White House Fellow and a member of the Institute for Advanced Study in Princeton. Professor Sarotte is also a member of the Council on Foreign Relations.

Almost every company is asking the question of survivability – how to balance business needs and growth, while meeting regulatory compliance and mitigating security risks? This question is facing organizations of all sizes, and for some the answer is changing the mission and scope of their IT security initiatives. In this session, Malcolm will discuss Intel’s approach to managing risk with its new “Protect to Enable” information security strategy.

Malcolm Harkins is vice president of the Information Technology Group and chief information security officer (CISO) and general manager of Information Risk and Security. The group is responsible for managing the risk, controls, privacy, security and other related compliance activities for all of Intel Corporation's information assets.

Before becoming Intel's first CISO, Harkins held roles in Finance, Procurement and Operations. He has managed efforts encompassing IT benchmarking and Sarbanes Oxley systems compliance. Joining Intel in 1992, Harkins previously held positions as the profit and loss manager for the Flash Products Group; general manager of Enterprise Capabilities, responsible for the delivery and support of Intel's finance and HR systems; and in an Intel business venture focusing on e-commerce hosting. Harkins previously taught at the CIO institute at the UCLA Anderson School of Business and was an adjunct faculty member at Susquehanna University in Pennsylvania. He received the 'Excellence in the Field of Security' award from the RSA conference as well as an Intel Achievement Award. Harkins received his bachelor's degree in economics from the University of California at Irvine and an MBA in finance and accounting from the University of California at Davis.

Dramatic improvements and cost reductions in renewable energy technologies have occurred over the past decade and even greater improvements are expected in the years to come. In addition, plentiful unconventional gas resources in North America and potentially broadly around the world provide prospects for a long-term lower carbon-emitting fossil fuel for electricity production and other uses. This optimistic outlook is in stark contrast to the energy situation in developing countries. Even today, several billion people lack access to electricity and clean cooking fuels. Additionally, industries in these developing countries--which are crucial for raising people from poverty, suffer from unreliable electricity and fuel supplies, which dramatically lowers productivity. This talk will first discuss the promising developments in advanced energy technologies and then explore the prospects, challenges and options for addressing energy access in the developing countries.
