November 2019 Update: 
Paper published: Do, Young Kyung. "Causal Effect of Sleep Duration on Body Weight in Adolescents: A Population-based Study Using a Natural Experiment." Epidemiology 30, no. 6 (2019): 876-884.

 

Despite a large number of observational studies consistently reporting the association between shorter sleep duration and higher body weight, causality has yet to be established at a population level. This study aims to estimate the population-level causal effect of sleep duration on adolescent body weight, using an instrumental variable (IV) approach that exploits a unique natural experiment in the context of South Korea’s highly competitive secondary education. In March 2011, amid growing concerns over the negative consequences of late-night tuition at private tutoring institutes (hagwon), authorities in 3 of the 16 administrative regions in South Korea decreed adjusting the closing hours of hagwon to 10 p.m. This policy change caused a substantial and plausibly exogenous variation in the sleep duration of the “marginal student,” whose sleep duration is most likely to be affected by the policy. The IV estimation results on a sample of general high school 10th- and 11th-graders in the 2009−2012 Korea Youth Risk Behavior Web-based Survey show that a 1-hour increase in sleep duration led to a 0.56 kg/m2 reduction in body mass index, or a 4.3 percentage-point decrease in overweight/obesity. Short sleep duration among adolescents may be an important contributor to increased body weight at the population level.

Microblogs, Youtube, and mobile communications. These are a few of the digital platforms changing how we connect, and subsequently, reshaping global societies. 

Confluence of technology and pervasive desire for information has in effect created widespread adoption. There is no doubt the Information Technology (IT) revolution is in full swing.

Comparing case studies across Asia and the United States, the fifth and final Stanford Kyoto Trans-Asian Dialogue (DISCONTINUED) considered opportunities and challenges posed by digital media. Experts and top-level administrators from Stanford and universities across Asia, as well as policymakers, journalists, and business professionals, met in Kyoto on Sept. 12-13, 2013.

Relevant questions asked included: What shifts have occurred in traditional versus digital media for how people get information, and how does this differ across countries? What is the potential for digital media in civil society and democratization? Is it a force for positive change or a source of instability?

In the presentations and discussion sessions, participants raised a number of key, policy-relevant points, which are highlighted in the Dialogue’s final report. These include:

Digital media does not, on its own, automatically revolutionize politics or foster greater democratization. While the Internet and digital media can play an instrumental role, particularly where traditional media is highly controlled by the government, participants cautioned against overemphasizing the hype. One conception is that the Internet can instead be viewed as a catalyst or powerful multiplier, but only if a casual chain of latent interest exists. That being said, greater exposure of youth to digital media, particularly in areas of tight media control, can open new areas of awareness.

The upending of traditional media business models has not been replaced by viable digital media business models. As media organizations struggle with their business models, the quality of reporting is threatened. For traditional organizations, maintaining public trust can be challenging, particularly during wars after disasters, while in areas with previously tightly controlled press, digital media may be perceived as more authentic. On the one hand, policy-driven agenda setting may be easier in some issue areas, but digital media may amplify interest in controversial issues, particularly with history issues in Asia.

As Cloud Computing platforms provided by a small group of mostly U.S. companies is increasingly the underlying platform for digital media—as well as our digital lives in general—issues of information security and privacy are at the forefront of much of the public’s mind. Revelations by former U.S. contractor Edward Snowden about the extent of the US government’s espionage activities raise concerns among journalists concerned with issues such as free speech of the press, media independence from government, and protection of sources. 

Previous Dialogues have brought together a diverse range of scholars and thought leaders from Japan, South Korea, China, Vietnam, Thailand, Indonesia, Singapore, India, Australia and the United States. Participants have explored issues such as the global environmental and economic impacts of energy usage in Asia and the United States; the question of building an East Asian regional organization; and addressing higher education policy and the dramatic demographic shift across Asia.

The annual Stanford Kyoto Trans-Asian Dialogue was made possible through the generosity of the City of Kyoto, the Freeman Spogli Institute for International Studies at Stanford University, and Yumi and Yasunori Kaneko.

“Teaching doesn’t stop after class—it shapes and develops into many different avenues.”

Perhaps this is a guiding belief behind Gi-Wook Shin, director of the Walter H. Shorenstein Asia Pacific Research Center (Shorenstein APARC) at Stanford.

Known for his directorship at Shorenstein APARC, Shin is also recognized as a professor of sociology and in the leading role of the Korea Program that he founded more than a decade ago. In this inaugural Faculty Spotlight Q&A, Shin talks courses, research and administration—and perhaps most poignantly—about the ongoing collaboration with students far beyond their time at Stanford.

What are you looking forward to with the Center in year 2014?

As you may know, Shorenstein APARC is entering its thirty-first year and we have much to be pleased with. Our six well-established programs are strong in their approach to interdisciplinary research and policy-oriented outcomes. As director, my goal is to support the success of these programs in broaching questions and guiding purposeful interaction between the United States and Asia.

Political transition, demographic change, and economic development are being seen at varying levels across Asia. At the same time, regional tensions continue to rise and shifting internal dynamics signal unrest. The need for dialogue and new perspectives is essential. We must ask the question: how can we constructively engage?

In February, for example, the Koret Conference will examine opportunities for the outside world to engage with North Korea. Given the current security situation, this dialogue is not incredibly easy, but it is essential. This conference will bring experts to Stanford’s campus who will create a strong policy report and offer insight into the foreign policy debate. The year ahead at Shorenstein APARC presents many opportunities for students, affiliates, and the surrounding community to become involved.

This quarter, you are teaching the course “Nations & Nationalism” and often teach a variety of comparative courses on politics and sociology – what do you find most challenging about teaching?

Shin: For me, a challenging aspect of teaching is finding a balance between teaching theory and equipping students with the tools to approach real-world problems. I do not wish for students to leave with purely theoretical and scholarly arguments; my aim is to give students the means to ask questions and prepare them to sort out today’s complex challenges.

Nationalism remains an important challenge. As we can see in Northeast Asia today, the tension among China, Japan and the Koreas speaks to the interdisciplinary relationship between nation and society—political ramifications caused in part by long-standing historical narratives. In my course, students survey major works and consider a wide range of regional and domestic factors that contribute to political identity. 

Having been at Stanford since 2001 as a senior fellow at FSI and a professor of sociology, what do you most enjoy about working here?

Shin: Stanford provides constant opportunities to learn and engage with new people. Fellows and corporate affiliates join us at Shorenstein APARC each year. It is a pleasure to meet, work and engage in conversation with such a wide variety of scholars and professionals. This is what I have enjoyed most about the Stanford community—meeting very good people in my 13 years here.

It’s especially rewarding to see my students succeed after their time at Stanford. Even after leaving campus, many of my former students continue to work in collaboration with me. For instance, I worked with Paul Chang, an assistant professor of sociology at Harvard University, on a research project on social movements in Korea, which produced articles and a book. Currently, I am working on two collaborative projects with doctorate students I previously taught—one on global talent in Korea and the other on cultural diversity in Asian higher education and corporations.

Can you tell us about your research collaboration and upcoming work?

At present, I am working on three major research projects. My first project is a collaborative one with my former student, Joon Nak Choi, who is now an assistant professor at the Hong Kong University of Science & Technology. Our book, which is currently under review by a major academic press, examines the spread of global talent from the viewpoint of social capital instead of human capital. While the “brain drain” perspective permeates most literature on global talent recruitment, we claim that the spread of global talent generates social capital, creates transnational bridges, and transfers positive returns back to the home country. As a Korean who has lived and worked in the United States for more than 30 years, this inquiry is especially salient to me.

A second project with another former student, Rennie Moon, an assistant professor at Yonsei University in Seoul, examines cultural diversity issues and challenges in Korea and Asia. We review current programs and policies in universities and corporations and investigate how promoting diversity in ethnically homogenous societies like Korea and Japan can contribute to innovation and creativity. Through this project, we seek to stimulate a much-needed conversation about the value of diversity in Korea and across Asia and what embracing diversity can mean and do for these societies. 

Similarly, I have been working on the final installment of the Divided Memories and Reconciliation project with Daniel C. Sneider, associate director for research at Shorenstein APARC. Through in-depth interviews with over 50 opinion leaders in Japan, Korea, South Korea and the United States, we have gathered and analyzed opinions on memories of the Pacific wars, which have become even more relevant as they manifest in current geopolitics. We are currently writing a book based on the interviews and this will conclude a multi-year research project on the Divided Memories that will have produced four books when this gets published.

All of these projects are based on rigorous academic research but also seek to draw policy implications and suggestions to solve real world issues and problems.

The Faculty Spotlight Q&A series highlights a different faculty member at Shorenstein APARC each month giving a personal look at his or her teaching approaches and outlook on related topics and upcoming activities.

Stephen W. Bosworth, a former diplomat and expert on Korea, will spend the winter quarter at Stanford as a visiting lecturer.

Bosworth was a United States ambassador to three countries: South Korea (from 1997 to 2001); the Philippines (from 1984 to 1987); and Tunisia (from 1979 to 1981).

He was the President Barack Obama’s Special Representative for North Korea Policy between 2009 and 2011 and held several other senior positions at the State Department. He was a dean of the Fletcher School of Law and Diplomacy at Tufts University and is currently a senior fellow at Harvard’s Belfer Center for Science and International Affairs.

At Stanford, he will be a Payne Distinguished Lecturer at the Freeman Spogli Institute for International Studies, in residence at FSI’s Walter H. Shorenstein Asia-Pacific Research Center.

Prior to his arrival at Stanford University, Bosworth also served as the Director of Policy Planning, Principal Deputy Assistant Secretary of State for Inter-American Affairs, and Deputy Assistant Secretary for Economic Affairs, among other senior level positions at the State Department. Bosworth co-authored Chasing the Sun, Rethinking East Asian Policy in 2006, and focuses on U.S.-Asia foreign policy, energy security and inter-governmental relations.

The Payne lectureship, named after Frank and Arthur Payne, presents prominent speakers chosen for their international reputation as leaders who emphasize visionary thinking, a broad grasp of a given field, and the capacity to engage the larger community in important issues. Former FBI Director Robert Mueller is also spending this academic year as a Payne lecturer.

Bosworth will deliver three public lectures at Stanford. His first talk will focus on his extensive experience in the diplomatic service. The public lecture and reception will take place in the Bechtel Conference Center in Encina Hall on Feb. 3. The two other lectures will address negotiations and relations between North Korea and the U.S. management of its alliance with Japan and South Korea.

Abstract: I examine how the shift from an exam to a district based high school assignment rule impacts intergenerational mobility and residential inequality. A stylized model predicts that under district assignment, household income relative to one’s ability becomes a stronger predictor of achievement, and higher income households sort towards and increase housing prices in the better school districts. I test predictions utilizing a unique policy change from South Korea in the 1970s. High school admission had traditionally been exam based in South Korea. However, between 1974 and 1980 the central government shifted several cities to a school district based system. I find that the reform increased intergenerational income elasticity from 0.15 to 0.31, and that higher income households migrated to the reform cities. I next examine whether school districting altered residential land prices within a city using a first differenced boundary discontinuity design. By focusing on the immediate years before and after the creation of school districts in Seoul, I find that residential land prices increased by about 13% point more on average and by about 26% point across boundaries in the better school district. In sum, I find that the shift from a merit to a location based student assignment rule decreases intergenerational mobility and increases residential inequality.

Professor Lee's research intersects the fields of economic development, political economy, urban economics and public economics, and regionally focuses on Korea and East Asia. Some of his recent research on Korea examines the impact of economic sanctions on the urban elites in North Korea and the impact of education policy on intergenerational mobility in South Korea. His research also examines entrepreneurship and urban growth, the efficacy of disaster aid delivery, and the relationship between aid and trade. Professor Lee is a member of the US-Korea Scholar-Policymaker Nexus Program organized by the Mansfield Foundation and the Korea Foundation. He received his PhD in economics from Brown University, master of public policy from Duke University, and bachelor degree in architecture from Seoul National University. As he made the transition from architecture to economics, he worked as an architecture designer and real estate development consultant.

Daniel C. Sneider writes that relations between South Korea and Japan have noticeably deteriorated in the past few months. After a recent trip to Seoul, Sneider postures that diplomatic ties may be at their lowest since 1965. While the United States has attempted to promote dialogue, its hesitant intervention is unlikely to change the overall dynamic of the Japan-Korea relationship. Sneider suggests a more active U.S. mediation role, such as appointing a special envoy or negotiating reparations, may better encourage reconciliation and normalization of relations.

New Challenges for Maturing Democracies in Korea and Taiwan takes a creative and comparative view of the new challenges and dynamics confronting these maturing democracies.

Numerous works deal with political change in the two societies individually, but few adopt a comparative approach—and most focus mainly on the emergence of democracy or the politics of the democratization processes. This book, utilizing a broad, interdisciplinary approach, pays careful attention to post-democratization phenomena and the key issues that arise in maturing democracies.

“As two paradigmatic cases of democratic development, Korea and Taiwan are often seen as exemplars of both modernization and democratization. This volume both contributes and moves beyond this focus, looking forward to assess the maturation but also the risks to democracy in both countries. With its strong comparative focus and a sober appreciation of how hard it can be not to just to attain but to sustain democracy, it represents a major contribution."  

     — Benjamin Reilly, Dean, Sir Walter Murdoch School of Public Policy and International Affairs, Murdoch University

What emerges is a picture of two evolving democracies, now secure, but still imperfect and at times disappointing to their citizens—a common feature and challenge of democratic maturation. The book demonstrates that it will fall to the elected political leaders of these two countries to rise above narrow and immediate party interests to mobilize consensus and craft policies that will guide the structural adaptation and reinvigoration of the society and economy in an era that clearly presents for both countries not only steep challenges but also new opportunities.
