One of the fundamental challenges facing the United States Department of Homeland Security is the determination of what is critical in critical infrastructure systems such as water, Internet, power, energy, and transportation. Current practice is focused on single-point security audits of things like power plants, airport terminals, and refineries. But this approach does not identify the most vital components of any infrastructure which leads to an inadequate strategy and wasted funding. We show that single-point audits lead to the wrong conclusions and do not provide sufficient national security relative to the effort and money being spent. Instead, we propose an approach similar to social network analysis whereby a critical infrastructure is modeled as a network and then analyzed to identify the critical nodes and links. We present models and software to analyze such networks to obtain optimal resource allocation such that network risk is minimized. In the parlance of network science, our approach extends the theory of scale free networks to incorporate damage estimates for nodes and links. By exploiting the structure inherent in a network, we are able to allocate resources in the most optimal manner, which leads to a fundamentally different strategy than currently practiced.

He is the Chair of the MOVES Curriculum Committee and is also the Associate Director for Research for the Center for Homeland Defense and Security. His personal research has been primarily focused on human factors and training using virtual environments and computer gaming media with emphasis on navigation and wayfinding in large-scale virtual worlds. He is a Senior Editor of PRESENCE Journal, the MIT Press journal of teleoperators and virtual environments. He received his B.S. in Computer Science Engineering from the University of Illinois at Chicago in 1990 and his M.S. and D.Sc. degrees in Computer Science from The George Washington University in 1993 and 1995, respectively.

Ted Lewis is Professor of Computer Science and Academic Associate of the Homeland Security curriculum at the Naval Postgraduate School. He served as Sr. Vice President of Eastman Kodak Company, President and CEO of DaimlerChrysler Research, North America, Editor-in-Chief (twice) of IEEE Computer magazine and IEEE Software magazine, and has authored more than 100 papers and 30 books over the past 35 years on subjects ranging from software engineering, parallel processing, to hi-tech business. Currently, he teaches the Critical Infrastructure Protection course at NPS and does research in the application of network science to strategy and policy questions for the US Department of Homeland Security. Dr. Lewis' textbook, "Critical Infrastructure Protection in Homeland Security: Defending a Networked Nation" will be published by John Wiley & Sons, in April 2006.

Diplomatic maneuvering in response to the North Korean nuclear crisis has presented the United States, South Korea, and China each with strategic dilemmas that go beyond the issue of how to address the prospect of a nuclear North Korea. In response to the immediate question of how to denuclearize the Korean peninsula, a complicated triangular relationship between China, South Korea, and the United States has emerged that reflects longer-term strategic anxieties about the future of a revamped security order in Northeast Asia following the resolution of the North Korean nuclear crisis.

Increasingly, these three countries perceive that how the crisis is resolved, and the policies that each member of the triangle is likely to pursue as steps toward resolving the crisis, may influence their relative positions and regional influence after the immediate issue of North Korea's denuclearization--or North Korea's future--has been resolved. Strategic anxieties about the future of Northeast Asia may be emerging as an obstacle that is as serious as apparent North Korean intransigence in explaining the lack of progress in diplomatic efforts thus far. Based on interviews with foreign policy analysts representing each actor in the triangle, the presentation will attempt to explain how each country in the triangle perceives its respective foreign policy choices and how those choices might influence the interests of its neighbors in Northeast Asia.

Meeting the world's energy needs and at the same time reducing emissions of greenhouse gases is one of the grand challenges humans must face in this century. China's situation illustrates the magnitude of the challenge as well as any place in the world. Its economy is growing rapidly, energy shortages abound, and a primary source of energy is coal. This talk reviews China's current and projected future emissions of carbon dioxide, examines alternatives for meeting the combined goals of increasing energy supply and reducing emissions, and describes research underway to provide more options to meet the challenges China faces.

Lynn Orr focuses his research activities on the interactions of fluid phase behavior with multiphase flow in porous media, the design of gas injection processes for enhanced oil recovery, and C0₂ sequestration in subsurface porous media. In August 2005, Dr. Orr and the Global Climate and Energy Project hosted an international conference at Tsinghua University in Beijing, China, to explore opportunities for collaborative research to integrate advanced coal technologies with CO₂ capture and storage in China.

This series is co-sponsored with the Center for East Asian Studies at Stanford University.

About the series: The year 2005 marks the 60th anniversary of the end of Pacific War and Japan's unconditional surrender. Post-war Japan has embraced a new constitution that renounced war as a right of the nation and for the past six decades pursued economic growth under democratic government. Ironically, the years leading to this anniversary were filled with various disputes over territorial and historical issues with China and Korea and questions from neighboring countries whether Japanese society is shifting towards the right. Triggered by Prime Minister Koizumi's official visits to Yasukuni Shrine, which enshrines "A" class war criminals, anti-Japan sentiment is widely spreading among its neighboring countries, accompanied by strong nationalism, and is posing a potential threat to the political stability of the region.

This colloquium series will focus on Japan's relationship with China and Korea and the historical controversies that are central to their deteriorating political relationship. The series speakers will address the following questions: What are the historical roots of these controversies? How did post-war Japanese foreign policy effect and was effected by Japan's handling of its militaristic past? What is the nature of domestic politics of these three countries that politicizes these historical issues and influences their responses to one another?

Martin Krygier is Professor of Law at the University of New South Wales, Sydney, Australia, co-director of the European Law Centre, and a Fellow of the Academy of Social Sciences in Australia. He studied philosophy, politics, and law, and his doctorate is in the history of ideas. In June 2005 he was appointed recurrent visiting professor at the Centre for Social Studies, Academy of Sciences, Warsaw, and at present he is a Fellow at the Center for Advanced Study in the Behavioral Sciences, Stanford University.

His work spans a number of fields, including legal, political and social philosophy; communist and post-communist studies; sociology of law; the history of ideas. His work has been translated into French, Hungarian, Italian, Polish, Romanian, Spanish and Ukrainian. Apart from academic publications, he also writes for journals of public debate.

A book of his selected essays, Civil Passions, was published in July 2005. Two co-edited books have also appeared recently: Rethinking the Rule of Law after Communism (Central European University Press, Budapest) and Spreading Democracy and the Rule of Law? (Springer, Berlin). In 1997, he was invited to deliver the Boyer radio lectures for the Australian Broadcasting Commission. This resulted in a book, Between Fear and Hope: Hybrid Thoughts on Public Values.
