FSI researchers examine the role of energy sources from regulatory, economic and societal angles. The Program on Energy and Sustainable Development (PESD) investigates how the production and consumption of energy affect human welfare and environmental quality. Professors assess natural gas and coal markets, as well as the smart energy grid and how to create effective climate policy in an imperfect world. This includes how state-owned enterprises – like oil companies – affect energy markets around the world. Regulatory barriers are examined for understanding obstacles to lowering carbon in energy services. Realistic cap and trade policies in California are studied, as is the creation of a giant coal market in China.

Every summer, the Draper Hills Summer Fellows Program brings together international leaders who are pioneering new approaches to advance social and political change in some of the most challenging global contexts. The fellows spend three weeks living and taking classes on the Stanford campus, visiting Silicon Valley tech companies and building a network.
Representing business, government and the nonprofit sector, fellows are working on the frontlines of democratic change to combat the global rise of authoritarianism and populism. The Freeman Spogli Institute for International Studies spoke to five of the fellows about the impact of the Draper Hills program on their work and activism. These are their stories.

“I’ve been working for the Tunisian government for three years as an advisor to the Minister of Development, Investment and International Cooperation. I am leading the government reforms to improve Tunisia's ranking in the World Bank Competitiveness Report - Doing Business.
“In Tunisia, we’ve set up most of our democratic institutions, and now we want to improve the business environment to attract more investment in local businesses. Eight years ago, the people went into the streets demanding more jobs. The challenge in Tunisia right now is economic, that’s why economic reforms are important to our government.
“I think the impact of the Draper Hills program will be immediate. I’ve learned a lot here about the link between development and democracies, so it really covers the scope of my work. And it's been great to learn about the theoretical side — the professors are really speaking about things that impact our daily work.”

“Bibeksheel Nepali is basically a political startup. It’s a youth-led movement, and we’re focused on changing the norms and mindsets of the culture in Nepal. We work a lot with citizens to instill the values of transparency, empathy and humility because we think democracy needs to be more emotional instead of just logical. I think liberal democracy needs to be understood more in the context of humanity. So it’s an experiment that we're doing in Nepal.
“When we started with the experiment, we decided not to focus only on the state, but thought about a few more components: one is our citizens, another is the society and the third is the government. Nepal recently came out of a violent civil war, and we just built a new constitution that is much more tolerant. Transparency is another value that we want to instill, because of the long isolationist and autocratic dictatorship that has existed in the past.
“Draper Hills is bringing all of these practitioners together who are experimental and innovative. And the world needs better collaboration from people who really believe in the ideals of the 21st century, which are liberal, democratic and more humanistic. That’s one of the strongest aspects of the Draper Hills program.”

“I'm a lawyer — I specialize in cyber laws. My work throughout my career has been focused on ensuring responsible technology and the use of technology to fight crime. Two years ago I was appointed by the Supreme Court of India as Amicus Curiae on a matter related to protecting against the uploading of videos and images of gang rape and child pornography online.
“Some of the social media platforms had very good reporting mechanisms, whereas it was more hidden on other platforms. So we ensured that this issue was brought to the forefront so that people know that these are things that can be reported and some action can be taken. The whole idea was that as long as you identify such content at the earliest possible time, then you help the victim that much more.
“For me, balancing victims' rights with free speech is very important. This was a big dilemma that I faced, in terms of ‘How much of what I am doing is likely to stifle free speech?’ A lot of discussions at Draper Hills have helped formulate and structure my thoughts, and it's very nice to get the perspective from people from 26 other countries.”

“I'm involved in women's empowerment and education for girls in Morocco. And especially for women in rural areas — they are less privileged, and many of them don't know their rights. So my fight through JA Worldwide and my activism is to empower these women and to raise awareness about their rights and the importance of education for girls.
“Education for girls is really important in fighting discrimination against women. Education empowers women to become financially independent, say no to violence, and to get engaged in the public sphere. Through that, women can be a part of the democratic process not only by voting, but also by taking part from within and running for office.
At Draper Hills, we're deepening our knowledge about topics like the rule of law, democracy and human rights, and hearing many different perspectives. And importantly, we are building a great network to connect many intelligent people from around the world, and we will work together to foster democratic values.”
Q&A with Professor Rodney C. Ewing, Frank Stanton Professor in Nuclear Security and co-director at the Center for International Security and Cooperation (CISAC) in the Freeman Spogli Institute for International Studies (FSI). Interview with Katy Gabel Chui.
Your previous research with this team helped identify the types of radioactive particles that can become airborne and were transported away from Fukushima during the 2011 nuclear disaster.
This most recent paper goes further to show how these Cesium (Cs)-rich silica particles behave in several types of fluids, including simulated human lung fluid, concluding that the particles are fully dissolved in the latter after more than 35 years. What might that mean for human health in the Fukushima area and beyond?
The first breakthrough was the recognition that such particles, a few microns in diameter, existed, a discovery by Japanese scientists at the Meteorological Research Institute, Tsukuba, in 2013. The particles are important because they were dispersed over distances of tens of kilometers and were “carriers” of highly radioactive Cs. Our team’s previous work, led by Professor Satoshi Utsunomiya, mainly focused on the characterization of the particles and their constituents at the atomic-scale and surveyed their distribution in the area away from the Fukushima Daiichi nuclear power plants. Our earliest work from 2016 can be found online. A good summary of the history of the work on these cesium-rich microparticles was recently published in Scientific American.
This latest paper published in Chemosphere is the 6th in a series of papers on the Cs-rich microparticles. We describe the behavior of these particles when exposed to different types of fluids: ultra-pure water, artificial sea water and simulated lung fluid. The microparticles dissolve in all three fluids, reaching a long-term but a continuing, slow rate of release after just three days. Essentially, the calculated release rate of cesium depends on the rate of dissolution of the silica glass matrix and the initial size of the particles. In the simulated lung fluid, the particles are modelled to fully dissolve after more than 35 years.
What is the simulated lung fluid made of, and how does it work in simulation? How do you estimate 35 years?
The constituents of typical lung fluid were simply mixed to simulate its composition based on a recipe reported by previous studies. The lung fluid is different from the other solutions because it contains organic compounds and has a different chemistry, i.e., higher sodium and chlorine content. The estimates of residence time in the body assumes that the particles are inhaled and find their way to the pulmonary system. The calculation of residence time is based on assumptions about the size and composition of the microparticles, and we used the long-term release rate from the experiments. We assumed a spherical shape and a constant decrease in size as the leaching process continued. The rate can vary depending on the actual shape, internal texture, composition (such as occurrence of intrinsic Cs-phase inclusions), and precipitation of secondary phases that may form a “protective” coating on the cesium-rich microparticles (CsMPs). The rate of release was fastest in the simulated lung fluid.
The important result is to realize that the Cs-rich silica particles dissolve slowly in the environment and in the body. Essentially, the release extends for several decades.
How can nuclear energy experts and policy makers use this research to avoid future risk?
Understanding the form and composition of materials that host and disperse radionuclides is the first step in completing a careful dose calculation. Based on these results, the fraction of Cs contained in the silica particles will not be rapidly “flushed” through the environment or the body, but rather will be released over several decades.
Abstract: Ultrafast optical pump-probe studies of uranium dioxide (UO2) under pressure were performed in order to better understand the material's response to ionizing radiation. Photoexcitation generates oscillations in the time-resolved reflectivity at two distinct GHz-scale frequencies. The higher-frequency mode is attributed to a coherent longitudinal acoustic mode. The lower-frequency mode does not correspond to any known excitation under equilibrium conditions. The frequency and lifetime of the low-frequency mode are studied as a function of pressure. Abrupt changes in the pressure-dependent slopes of these attributes are observed at ∼10 GPa, which correlates with an electronic transition in UO2. Variation of probe wavelength reveals that the low-k dispersion of the low-frequency mode does not fit into either an optical or acoustic framework. Rather, we propose that this mode is related to the dynamical magnetic structure of UO2. The implications of these results help account for the anomalously small volume of damage known to be caused by ionizing radiation in UO2; we propose that the existence of the low-frequency mode enhances the material's transient thermal conductivity, while its long lifetime lengthens the timescale over which energy is dissipated. Both mechanisms enhance damage recovery.
Abstract: To understand the chemical durability of highly radioactive cesium-rich microparticles (CsMPs) released from the Fukushima Daiichi Nuclear Power Plant in March 2011, we have, for the first time, performed systematic dissolution experiments with CsMPs isolated from Fukushima soils (one sample with 108 Bq and one sample with 57.8 Bq of 137Cs) using three types of solutions: simulated lung fluid, ultrapure water, and artificial sea water, at 25 and 37 °C for 1–63 days. The 137Cs was released rapidly within three days and then steady-state dissolution was achieved for each solution type. The steady-state 137Cs release rate at 25 °C was determined to be 4.7 × 103, 1.3 × 103, and 1. 3 × 103 Bq·m−2 s−1 for simulated lung fluid, ultrapure water, and artificial sea water, respectively. This indicates that the simulated lung fluid promotes the dissolution of CsMPs. The dissolution of CsMPs is similar to that of Si-based glass and is affected by the surface moisture conditions. In addition, the Cs release from the CsMPs is constrained by the rate-limiting dissolution of silicate matrix. Based on our results, CsMPs with ∼2 Bq, which can be potentially inhaled and deposited in the alveolar region, are completely dissolved after >35 years. Further, CsMPs could remain in the environment for several decades; as such, CsMPs are important factors contributing to the long-term impacts of radioactive Cs in the environment.

Abstract: How do nuclear-armed states coerce their adversaries in wars with limited aims without using nuclear weapons? I develop a theory of strategic substitution to explain why states use space, cyber and conventional missile weapons instead of nuclear weapons to maximize leverage against their adversaries. I also explain how they select space, cyber, and conventional missile force postures, defined as weapons and plans for using them. Threats to use space, cyber and conventional missile weapons are more credible sources of strategic leverage against adversaries in wars that do not threaten a state’s survival. I demonstrate the plausibility of the theory using China’s cyber force posture. China developed space, cyber and conventional missile weapons to solve a common problem: giving Beijing the leverage it could not gain from its nuclear weapons in a future war over Taiwanese independence involving the United States. Using original Chinese-language written sources and interviews conducted during extensive fieldwork, I show that Chinese leaders pursued cyber weapons to maximize their strategic leverage after the United States bombed the Chinese Embassy in Belgrade in 1999. As China’s vulnerability to cyber attacks grew during the 2000s, its appetite for risk in using cyber weapons declined, resulting in a change to its military cyber force posture in 2014.
Speaker Bio: Fiona Cunningham is a Post-Doctoral Fellow at CISAC. Her research interests lie at the intersection of technology and conflict, with an empirical focus on China. She received her PhD in September 2018 from the Department of Political Science at the Massachusetts Institute of Technology (MIT), where she was a member of the Security Studies Program. Her dissertation explained China’s development of space, cyber and conventional missile force postures as substitutes for using nuclear weapons to coerce adversaries. Her research is based on extensive fieldwork, including a year-long dissertation research fellowship at the Renmin University of China, Beijing, in 2015-6. She was a Pre-Doctoral Fellow in the Cyber Security Project at the Belfer Center for Science and International Affairs at the Kennedy School of Government, Harvard University, in 2017-8. Fiona’s research has been supported by the Smith Richardson Foundation, China Confucius Studies Program, and the MIT Center for International Studies.

Fiona holds a Bachelor of Arts in Politics and International Relations from the University of New South Wales and a Bachelor of Laws from the University of Sydney, both with first-class honors. She was a research associate at the Lowy Institute for International Policy in Sydney from 2009 until 2012, where she focused on extended nuclear deterrence in East Asia and nuclear nonproliferation. Fiona speaks Mandarin Chinese and French.
We assess scientific evidence that has emerged since the U.S. Environmental Protection Agency’s 2009 Endangerment Finding for six well-mixed greenhouse gases and find that this new evidence lends increased support to the conclusion that these gases pose a danger to public health and welfare. Newly available evidence about a wide range of observed and projected impacts strengthens the association between the risk of some of these impacts and anthropogenic climate change, indicates that some impacts or combinations of impacts have the potential to be more severe than previously understood, and identifies substantial risk of additional impacts through processes and pathways not considered in the Endangerment Finding.
