About the Topic: The Internet in 2014 is a marvelous communication utility. It provides cheap and fast transfer of information to and from most places on or near the surface of Earth. It also regularly betrays that information to curious onlookers, commercial entities, criminals, and governments.  We will explore the origins of the Internet, the workings of its core protocols, exploits which take advantage of those protocols, and feeble attempts to make those protocols secure. In sum, we will describe the devolution of the Internet from a peaceful commons to the jungle it is today.

Abstract:

Nipah virus lives in large fruit bats in South and Southeast Asia. When people become infected with Nipah virus over half of them die. Nipah virus can also be transmitted from person to person. This talk will describe how this bat virus occasionally infects human populations and causes outbreaks through person-to-person transmission. It will explore the risk of a global pandemic of Nipah virus and consider appropriate policy responses.

Speaker bio:

Stephen Luby is Professor of Medicine in the Division of Infectious Diseases and Geographic Medicine; Deputy Director for Research at the Center for Global Health Innovation; Senior Fellow at the Woods Institute for the Environment and Senior Fellow at the Freeman Spogli Institute for International Studies at Stanford University.

Dr. Luby studied philosophy and earned a Bachelor of Arts summa cum laude from Creighton University. Dr. Luby earned his medical degree from the University of Texas Southwestern Medical School at Dallas and completed his residency in internal medicine at the University of Rochester-Strong Memorial Hospital. He studied epidemiology and preventive medicine at the Centers for Disease Control and Prevention.

Dr. Luby's former positions include leading the Epidemiology Unit of the Community Health Sciences Department at the Aga Khan University in Karachi, Pakistan for 5 years and working as a Medical Epidemiologist in the Foodborne and Diarrheal Diseases Branch of the Centers for Disease Control and Prevention exploring causes and prevention of diarrheal disease in settings where diarrhea is a leading cause of childhood death.  Immediately prior to his current appointment, Dr. Luby served for eight years at the International Centre for Diarrheal Diseases Research, Bangladesh (ICDDR,B), where he directed the Centre for Communicable Diseases. Dr. Luby was seconded from the US Centers for Disease Control and Prevention (CDC) and was the Country Director for CDC in Bangladesh.

Dr. Luby's research has focused on clarifying the burden of several communicable diseases in low income countries and developing and evaluating practical strategies to mitigate their impact. He is currently exploring circumstances where economic and political forces encourage environmental degradation that exerts substantial disease burden in low income countries, with a view to developing and evaluating interventions.

Africa (Proceedings of the National Academy of Sciences 2013): USAID and the UN's World Food Program have proposed strategies for allocating ready-to-use (therapeutic and supplementary) foods to children in developing countries. Analysis is needed to investigate whether there are better alternatives. We use a longitudinal data set of 5657 children from Bwamanda to construct a statistical model that tracks each child's height and weight  throughout the first five years of life. We embed this model into an optimization framework that chooses which individual children should receive food based on a child's sex, age, height and weight, to minimize the mean number of disability-adjusted life years per child subject to a budget constraint. Our proposed policy compares favorably to those proposed by the aid groups. Time permitting, we will also discuss a recent analysis of a nutrition program in Guatemala that quantifies the age dependence in the impact of supplementary food, and develops a food allocation policy that exploits this age dependence and reduces child stunting.

India: Motivated by India's nationwide biometric program for social inclusion, we analyze verification (i.e., one-to-one matching) in the case where we possess 12 similarity scores (for 10 fingerprints and two irises) between a resident's biometric images at enrollment and his biometric images during his first verification. At subsequent verifications, we allow individualized strategies based on these 12 scores: we acquire a subset of the 12 images, get new scores for this subset that quantify the similarity to the corresponding enrollment images, and use the likelihood ratio to decide whether a resident is genuine or an imposter. Compared to the policy currently used in India, our proposed policy provides a five-log (i.e., 100,000-fold) reduction in the false reject rate while only increasing the mean delay from 31 to 38 seconds.

Over the last several years the landscape for money movement has changed dramatically. Non-state-backed digital currencies such as Bitcoin have introduced new paradigms for money movement in which transfers are public but the identities of the individuals behind the transfers are masked. Traditional currencies are being moved in novel ways as well. In the developing world, unbanked populations are engaging in an increasingly sophisticated array of financial transactions using mobile phone-based mobile money services.

These changes present both opportunities and challenges. Mobile money, for example, has become a vital tool for financial inclusion for tens of millions of people in the developing world. Yet, all mechanisms for moving (and storing) money—new and old—involve risks and the potential for misuse. This seminar, which will be structured as a highly interactive facilitated discussion, aims to explore ways to realize the benefits of technologically facilitated money movement, while also providing frameworks minimizing the risk of misuse.

About the Topic: This presentation includes a review of significant trends in the development of nuclear energy in China, from the mid1980's until the present, and related future prospects. Among the subjects covered will be: nuclear technology development based on competition/cooperation between a giant state owned enterprise and an upstart commercial utility from the south; different development goals and technology development by the two corporations; the impact of Fukushima on nuclear energy developments in China; the current status of the Chinese nuclear energy system; future growth prospects considering a range of different challenges in the industry; and nuclear technology development prospects and intellectual property issues.

About the Speaker: Chaim Braun is a consulting professor at CISAC specializing in issues related to nuclear power economics and fuel supply, and nuclear nonproliferation. Braun pioneered the concept of proliferation rings dealing with the implications of the A.Q. Khan nuclear technology smuggling ring, the concept of the Energy Security Initiative (ESI), and the re-evaluation of nuclear fuel supply assurance measures, including nuclear fuel lease and take-back. Before joining CISAC, Braun worked as a member of Bechtel Power Corporation's Nuclear Management Group, and led studies on power plant performance and economics used to support maintenance services. Prior to that, Braun worked at United Engineers and Constructors (UE&C), EPRI and Brookhaven National Laboratory (BNL).

About the Topic: Re-establishing and strengthening the rule of international law in international affairs was a central Allied aim in the First World War. Revisionism in its many forms has erased this from our memory, and with it the meaning of the war. Imperial Germany’s actions and justifications for its war conduct amounted to proposing an entirely different set of international-legal principles from those that other European states recognized as public law. This talk examines what those principles were and what implications they had for the legal world order.

About the Speaker: Isabel V. Hull received her Ph.D. from Yale University in 1978 and has since then been teaching at Cornell University, where she is the John Stambaugh Professor of History. A German historian, her work has reached backward to 1600 and forward to 1918 and has focused on the history of sexuality, the development of civil society, military culture, and imperial politics and governance. She has recently completed a book comparing Imperial Germany, Great Britain, and France during World War I and the impact of international law on their respective conduct of the war. It will appear in Spring 2014 under the title, A Scrap of Paper: Breaking and Making International Law in the First World War. Her talk is based on this latest research.

ABOUT THE TOPIC: Culture is often understood as a system of "shared understandings." But what does that mean? Amir Goldberg argues that having a shared understanding with others does not necessarily imply espousing similar beliefs or attitudes. Rather, culture prescribes which beliefs and attitudes go with one another; sharing an understanding therefore suggests being in agreement about the structures of relevance and opposition that make symbols and actions meaningful. Amir uses relational class analysis - a network-based method for analyzing survey data - to map these structures, and find groups of people who share distinctive cultural schemes. This approach lends new insights into understanding the social underpinnings of Americans' complex understandings of music, politics, economic morality, and more.

ABOUT THE SPEAKER: Professor Goldberg received bachelors' degrees in Computer Science and Film Studies from Tel Aviv University, and an MA in Sociology from Goldsmith’s College, University of London. Before pursuing a PhD in Sociology at Princeton University, he worked for several years as a software programmer, an IT consultant and a technology journalist. An Assistant Professor of Organizational Behavior in Stanford’s Graduate School of Business, his research projects all share an overarching theme: the desire to understand the social mechanisms that underlie how people construct meaning, and consequently pursue action. His work has been published in the American Journal of Sociology, and he was awarded Princeton University’s Harold W. Dodds Honorific Fellowship.

ABOUT THE COMMENTATOR: Marc Ventresca is University Lecturer in Strategic Management at Said Business School (University of Oxford), England's foremost graduate school of business. Dr. Ventresca, who earned his PhD in Sociology at Stanford, specializes in governance, entrepreneurship, market and network formation, and technology strategy.
