She was the Colin and Nancy Campbell Professor of Global Issues and Democratic Thought and professor of government at Wesleyan University in Middletown, Conn., from 1974 to 2007. Her current research focuses on innovation in terrorist campaigns, the distinction between "old" and "new" terrorism, how terrorism ends, and why the United States is the target of terrorism. She serves on the Executive Board of Women in International Security and chairs the American Political Science Association (APSA) Task Force on Political Violence and Terrorism. She has served on the Council of the APSA and is a former President and Councilor of the International Society of Political Psychology (ISPP).

Homeland security remains a house divided. Within the Department of Homeland Security (DHS), which incorporated 22 disparate agencies four years ago, major challenges persist in building cohesion and cooperation across Department boundaries. Difficulties also exist for strengthening interagency cooperation between DHS and the other federal Departments (ranging from Defense to Health and Human Services) with homeland security responsibilities. Still greater challenges lie in building cooperation beyond the federal government. States, localities and the private sector are critical to homeland security, but do not ordinarily fall under the president's command, and have their own priorities related to infrastructure protection, disaster preparedness, and other key functions. The profoundly non-hierarchical structure of the homeland security system requires unprecedented efforts to create unity of effort: that is, coordination and cooperation to accomplish mutually agreed objectives, by components of the government and private sector that typically cannot order each other what to do.

The CISAC Forum on Homeland Security will enable approximately 25 private sector leaders, senior government officials and scholars to share insights on homeland security beyond their usual realms of interaction. We would like to launch a dialogue between participants on the problems that exist in creating coordination and collaboration in homeland security, how unity of effort might be defined (and ultimately measured in terms of effectiveness) as a means to overcome those problems, and how different approaches in industry and government might be adapted to fill specific gaps in homeland security cooperation. The conference will conclude with an effort to reach consensus on initiatives that seem most promising to pursue, both for action by policymakers and industry leaders and for analysis in follow-on discussions and academic research.

Suicide bombings targeting Israeli civilians were once the favored tactic of Palestinian terrorists. Israeli deaths from suicide bombings peaked in the spring of 2002, but Israeli countermeasures dramatically lowered the number of successful suicide bombings since then. This talk will assess the impact of various countermeasures on suicide bombing rates with an eye towards understanding the decline in successful suicide bombings in Israel.

Edward H. Kaplan is the William N. and Marie A. Beach Professor of Management Sciences at the Yale School of Management, a professor of public health at the Yale School of Medicine, and professor of engineering in the Yale Faculty of Engineering. An elected member of the National Academy of Engineering and the Institute of Medicine, Kaplan uses operations research and statistical methods to study problems in public policy and management. His earlier work was devoted to evaluating HIV prevention programs, while his more recent studies focus on counterterror topics such as the tactical prevention of suicide bombings and response logistics in the event of a bioterror attack. He has also dabbled in predicting the outcomes of presidential elections and NCAA basketball tournaments. His efforts have been recognized with several awards in the fields of operations research and public health.

Eileen Chamberlain Donahoe (speaker) is a visiting scholar at CISAC. Her PhD dissertation, entitled "Humanitarian Military Intervention: the Moral Imperative Versus the Rule of Law," focused on conflicting ethical and legal justifications for humanitarian military intervention. In an earlier publication, The Promise of Law for the Post-Mao Leadership in China, she examined the prospects for the development of the rule of law in China. Future projects will address the rule of law with respect to norms on use of force.

Donahoe earned her PhD in ethics and social theory from the Graduate Theological Union at the University of California Berkeley. She holds a JD from Stanford law school and an MA in East Asian studies from Stanford. She also earned an MA in theological studies from Harvard and spent a year studying Mandarin at Nankai University in Tianjin. After law school, Donahoe clerked for the Hon. William H. Orrick of the United States Federal District Court for the Northern District of California. She served as a teaching fellow at Stanford Law School and practiced high-tech litigation at Fenwick & West in Palo Alto, CA. She is a member of the California Bar.

Laura Donohue (respondent) is a fellow at CISAC and at Stanford Law School's Center for Constitutional Law. Donohue's research focuses on national security and counterterrorist law in the United States, United Kingdom, Republic of Ireland, Israel, and the Republic of Turkey. Prior to Stanford, Donohue was a fellow at Harvard University's John F. Kennedy School of Government, where she served on the Executive Session for Domestic Preparedness and the International Security Program. In 2001 the Carnegie Corporation named her to its Scholars Program, funding the project, "Security and Freedom in the Face of Terrorism." At Stanford, Donohue directed a project for the United States Departments of Justice and State and, later, Homeland Security, on mass-casualty terrorist incidents. She has written numerous articles on counterterrorism in liberal, democratic states. Author of Counter-terrorist Law and Emergency Powers in the United Kingdom 1922-2000, she is completing a manuscript for Cambridge University Press analyzing the impact of British and American counterterrorist law on life, liberty, property, privacy, and free speech. Donohue obtained her AB (with honors, in philosophy) from Dartmouth College, her MA (with distinction, in war and peace studies) from University of Ulster, Northern Ireland, and her PhD in history from the University of Cambridge. She received her JD from Stanford Law School.
