About the Topic: Analysis of environmental samples collected for nuclear forensics purposes typically involves determination of isotopic composition, which can sometimes (but not always) reveal information about nuclear events or processes that resulted in the anthropogenic radioactivity. This information is referred to as the “isotopic signature”.  Sequential extractions have been used for many years to determine chemical forms of contaminants for environmental regulatory purposes and clean-up decisions, and they can reveal “chemical signatures” about the events or processes that resulted in contamination.  Coupling sequential extractions with isotopic determinations in nuclear forensics analyses provides an opportunity to link isotopic and chemical signatures, which can improve confidence in identifying the relevant nuclear event or process. This approach shows promise, particularly when coupled with nuclear fuel cycle process knowledge.  Examples involving contaminated nuclear sites in the US and Russia will be discussed.

About the Topic: Air, sea, land, and space are the traditional domains of military operations. Now, as the Information Age unfolds, cyberspace has become the fifth domain. The relative newness of cyberspace and the interdependencies between it and the preexisting domains pose many challenges, both in terms of the wise integration of cyber into ongoing operations and the creation of personnel with the right combination of technical and non-technical knowledge to apply activities on computers and networks in ways consistent with high-level policy. Cyber operations include both the defense of networks and computers, but also actions to achieve specific effects on adversaries.  These effects may extend to the physical world, or may be circumscribed entirely to cyber systems. Through examples and observations, this unclassified talk will illustrate the complexity of our quest to use cyber space.

About the Speaker: Dr. Cynthia Irvine is the chair of the Cyber Academic Group and director of the Center for Information Systems Security Studies and Research (CISR) at the Naval Postgraduate School where she is a professor of computer science. Her research centers on the design and construction of secure high assurance systems and multilevel security, and now cyber systems and operations. She is an author on over 160 papers and reports and has supervised the research of over 140 Masters and PhD students. Dr. Irvine is a recipient of the Naval Information Assurance Award and the William Hugh Murray Founder’s Award from the Colloquium for Information Systems Security Education. She is a member of the Association for Computing Machinery, a lifetime member of the Astronomical Society of the Pacific, and a Golden Core Member of the Institute of Electrical and Electronics Engineers (IEEE). From 2005 through 2009, she served as Vice- Chair and subsequently as Chair of the IEEE Technical Committee on Security and Privacy.

Abstract
This talk reports on a study about the impact of crowdsourcing on a law-making process in Finland. In the studied process, the reform of off-road traffic law was opened for public participation in Finland. The citizens were first asked to share their experiences and problems with off-road traffic and the regulating law on an online platform. Then the participants were asked to share solutions for those problems. Crowdsourcing resulted into 500 ideas, over 4,000 comments and 24,000 votes, which were analyzed and evaluated both with citizens and experts and using an algorithmic consensus tool. The talk discusses deliberative aspects in crowdsourcing and the usefulness of blended expertise, i.e. the mixture of the crowd's and experts' knowledge, in law-making.

Tanja Aitamurto is a visiting researcher at the Program on Liberation Technology at the Center on Democracy, Development and the Rule of Law at Stanford. In her PhD project she examines how collective intelligence, whether harvested by crowdsourcing, co-creation or open innovation, impacts incumbent processes in journalism, public policy making and design process. Her work has been published in several academic publications, such as the New Media and Society. Related to her studies, she advises the Government and the Parliament of Finland about Open Government principles, for example about how open data and crowdsourcing can serve democratic processes.

Aitamurto has previously studied at the Center for Design Research and at the Innovation Journalism Program at Stanford. She is a PhD Student at the Center for Journalism, Media and Communication Research at Tampere University in Finland, and she holds a Master’s Degree in Public Policy, and a Master of Arts in Humanities. Prior to returning to academia, she made a career in journalism in Finland specializing in foreign affairs, doing reporting in countries such as Afghanistan, Angola and Uganda. She has also taught journalism at the University of Zambia, in Lusaka, and worked at the Namibia Press Agency, Windhoek. More about Tanja’s work at www.tanjaaitamurto.com and on Twitter @tanjaaita.

1953 saw both the signing of the Korean Armistice Agreement and a Mutual Defense Treaty between the United States and the Republic of Korea. The uneasy and incomplete peace, coupled with a formalized U.S.-ROK security alliance relationship, ushered in a new era on the Korean Peninsula. 2013 marks the 60th anniversary of these pivotal events.

Ambassador Stephens will draw from her experience in Korean affairs over the past four decades, including her tenure as U.S. ambassador to the ROK 2008-2011, to discuss the evolution of the bilateral alliance, its challenges and achievements, and major issues now and going forward. This lunchtime seminar is scheduled to occur immediately upon Ambassador Stephens' return from a visit to Seoul where she will have participated in a first-ever gathering of former American ambassadors to Korea and former Korean ambassadors to the U.S. aimed specifically at reflecting on the U.S.-ROK alliance at 60.  Her comments will also be informed by these discussions.

Ambassador Stephens recently completed thirty-five years as a career diplomat in the U.S. Foreign Service. She was Acting Under Secretary of State for Public Diplomacy and Public Affairs in 2012, and U.S. Ambassador to the Republic of Korea, 2008 to 2011.

Ambassador Stephens has served in numerous posts in Washington, Asia, and Europe. From 2005 to 2007 she was Principal Deputy Assistant Secretary of State for the Bureau of East Asian and Pacific Affairs (EAP). While Deputy Assistant Secretary of State in the Bureau of European and Eurasian Affairs (EUR) from 2003 to 2005, she focused on post-conflict and stabilization issues in the Balkans. She was Director for European Affairs at the National Security Council during the Clinton Administration.

Ambassador Stephens’ overseas postings included service in China, Korea, Yogoslavia, Northern Ireland, Portugal, and Trinidad & Tobago.

Ambassador Stephens received the 2009 Presidential Meritorious Service Award. Other awards and recognition include the Korean government’s Sejong Cultural Prize (2013), and in 2011 the Pacific Century Institute’s Building Bridges Award, the Outstanding Achievement Award from the American Chamber of Commerce in Korea, and the Kwanghwa Medal of Diplomatic Merit from the Korean government. Her book, Reflections of an American Ambassador to Korea, based on her Korean-language blog, was published in 2010.

Ambassador Stephens graduated from Prescott College, and holds a master's degree from Harvard University, along with honorary doctoral degrees from Chungnam National University and the University of Maryland. Ambassador Stephens studied at the University of Hong Kong. She was a Peace Corps volunteer in Korea in the 1970s.
