Using a dynamic microsimulation model, a research team, including APARC Deputy Director and Asia Health Policy Program Director Karen Eggleston, shows that there are differentially positive health gains of smoking reduction among subgroups of smokers in South Korea, Singapore, and the United States.

Tobacco use is responsible for the death of approximately eight million people worldwide, estimates the World Health Organization, and countries are increasingly making tobacco control a priority. Indeed the relationship between smoking and the burden of chronic diseases such as cancer, lung disease, and heart disease, and, in turn, premature mortality, is well documented. Yet little is known about the health effects of smoking interventions among subgroups of smokers.

Do interventions targeted at heavy smokers relative to light smokers lead to disproportionately larger improvements in life expectancy and prevalence of chronic diseases? And how do these effects vary across populations? In today’s rapidly aging world, it is crucial to understand the potential health gains resulting from interventions to reduce smoking, a leading preventable risk factor for healthy aging.

That’s why a research team, including APARC Deputy Director and Asia Health Policy Program Director Karen Eggleston as well as Stanford Health Policy faculty member Jay Bhattacharya, set out to examine the health effects of smoking reduction. To do so, the team simulated an elimination of smoking among subgroups of smokers in South Korea, Singapore, and the United States.

The team’s findings, discussed in a new paper published by the journal Health Economics, show that smoking reduction can achieve significant improvements in lifetime health as measured by survival while also reducing the prevalence of major chronic diseases, though the effects are heterogeneous. Whereas interventions in both subgroups and in all three countries led to an increased life expectancy and decreased prevalence of chronic diseases, the life-extension benefits were greatest – 2.5 to 3.7 years – for those who would otherwise have been heavy smokers, compared with gains of 0.2 to 1.5 years among light smokers.

The team developed a dynamic microsimulation model to estimate the health gains of reducing smoking among heavy smokers and light smokers. Microsimulation models are powerful tools for assessing the value of health promotion: they model individual health trajectories while accounting for competing risks, thus providing valuable information about the impact of interventions and how they may interact with the changing demographics and socioeconomic profile of a population to determine future health. The team’s study applied microsimulation models tailored to the demographic and epidemiological context in the three countries, then compared the gains in survival and reduction in chronic disease prevalence from a given reduction in smoking and how these impacts vary depending on initial smoking intensity.

The team’s findings indicate that there are differentially positive health effects from smoking reduction. The life‐year gain among heavy smokers quitting well exceeds that of light smokers quitting in each country, but the magnitudes differ substantially: 11.2 times for South Korea, 6.8 times for Singapore, and 1.7 times for the United States. The lower life expectancy among Americans is related to the greater extent in which they suffer from risk factors, such as obesity, relative to the Asian counterparts in the study.

The findings illustrate how smoking interventions may have significant economic and social benefits, especially for life extension, that vary across countries. They are particularly important for aging societies that are concerned about the sustainability of their health insurance systems in the face of increasing burden of chronic disease.

The science of cyber risk looks at a broad spectrum of risks across a variety of digital platforms. Often though, the work done within the field is limited by a failure to explore the knowledge of other fields, such as behavioral science, economics, law, management science, and political science. In a new Science Magazine article, “Cyber Risk Research Impeded by Disciplinary Barriers,” cyber risk experts and researchers at Stanford University make a compelling case for the importance of a cross-disciplinary approach. Gregory Falco, security researcher at the Program on Geopolitics, Technology, and Governance, and lead author of the paper, talked recently with the Cyber Policy Center about the need for a holistic approach, both within the study of cyber risk, and at a company level when an attack occurs.

CPC: Your recent perspective paper in Science Magazine highlights the issue of terminology when it comes to how organizations and institutions define a cyber attack. Why is it so important to have consistent naming when we are talking about cyber risk?

Falco: With any scientific discipline or field, there is a language for engaging with other experts. If there’s no consistent language or at least dialect for communication around cyber risk, it’s difficult to engage with scholars from different disciplines. For example: The phrase “cyber event” is contested and the threshold for what an organization considers to be a cyber event varies substantially. Some organizations consider someone pinging their network as a cyber event, others only consider something a cyber event once an intrusion has been publicly disclosed. So there’s a disparity when comparing metrics of cyber events from organization to organization because of the different thresholds of what’s considered an event.

CPC: We’ve all been sent one of those emails letting us know our data may have been compromised and your paper points out it’s nearly impossible to put foolproof protections into place; attacks are inevitable. Given that, how should companies weigh the various ways they can protect themselves?

Falco: The first exercise each organization should go through when they decide to be serious about cyber risk is to prioritize their assets. What is business critical? What is safety critical? Then, like all other risks, a cost-benefit analysis must be done for each asset based on its priority. If the asset is safety-critical, then resources should be allocated to help protect that asset or at least ensure its resilience. Trade-offs are inevitable, no company has unlimited resources. But starting with an understanding of where the priorities are, is critical.

CPC: In companies, cyber security often falls entirely to the Chief Information Security Officer (CISO). Your paper argues that’s shortsighted. What is gained when a company takes a more holistic approach?

Falco: Distributing responsibility across the organization catalyzes a security culture. A security culture is one where there is a constant vigilance or at least broad awareness of cybersecurity concerns throughout the organization. Fostering a security culture is often suggested as a mechanism to help reduce cyber risk in organizations. The problem with not distributing responsibility is that when something happens, it’s too easy to resort to finger-pointing at the CISO, and that’s counterproductive. Efforts after an attack should be on responding and being resilient, not finding the scapegoat.

CPC: Cyber risk largely focuses on prevention, but your paper argues that it’s what happens after an attack in that needs greater attention. Why is that?

Falco: Every organization will be attacked. However organizations can differentiate themselves from a cyber risk standpoint by appropriately managing the situation after an attack. Some of the most significant damages to organizations can be reputational if communication after an attack is unclear or botched. Poor communication after an attack can result in major regulatory fines or valuation adjustments as seen in cases like Yahoo and that can have major business implications. Communications aren’t the only important element of post-attack response. A thorough post-mortem of the organization’s response to the attack can be an important learning experience and a way to plan for future attacks.

CPC: Protecting against cyber attacks and the losses that go with them can obviously be costly for companies. You make a case for collaboration among different fields, say among data scientists and economists. How can that be encouraged?

Falco: We argue that cross-disciplinary collaboration rarely happens organically. Therefore, we call on funding agencies like the NSF or DARPA to specify a preference for cross disciplinary research when funding cyber risk projects. Typically, this isn’t currently a feature of calls for proposals, but for cyber risk programs it should be. We encourage researchers to explore cyber risk questions at the margins of their discipline. Those questions may lend themselves to potential overlap with other disciplines and foster a starting point for cross-disciplinary collaboration.

"Ideologically, today’s autocrats are a more motley and pragmatic crew. They generally claim to be market friendly, but mainly they are crony capitalists, who, like Putin in Russia, Orban in Hungary, and Erdogan in Turkey, are first concerned with enriching themselves, their families, and their parties and support networks. Increasingly, they raise a common flag of cultural conservatism, denouncing the moral license and weakness of the “the liberal West” while advancing a virulent antiliberal agenda based on nationalism and religion," writes Larry Diamond.

Of all of the countries in the world attempting a transition to democracy, Francis Fukuyama thinks that Ukraine is the most promising.

“The election of [Volodymyr] Zelensky and the new parliament is just a miracle,” Fukuyama told Freeman Spogli Institute for International Studies (FSI) Director Michael McFaul on the World Class podcast. “Can you imagine, a country getting rid of two-thirds of its parliament and starting over with new people, many of whom are under 35 years old?” 



Ukraine is at a crossroads of sorts, said Fukuyama, who is the Olivier Nomellini Senior Fellow at FSI, and the director of both the Center on Democracy, Development and the Rule of Law and the Ford Dorsey Master’s in International Policy program. On one hand, the country could use this opportunity to transition into a successful reformist government, or its efforts could fail and the government could collapse. 

It doesn’t help that Ukraine’s relationships with foreign allies are not as strong as they once were, he told McFaul.

“The United States had been their strongest ally, but now there’s a president in the White House who doesn’t particularly like them,” he explained. “I think Germany and France are also both weakening in their support for Ukraine’s independence, so [Ukraine is] in a really tough spot.”

Before Ukraine’s Orange Revolution in 2004, Fukuyama said he actually thought the country would be among the least likely to liberalize in the way that it has. One important factor in Ukraine’s success has been the exercise of broad individual and political freedoms —  for example, Ukraine’s press has stayed active throughout the years and the country boasts many investigative journalists, he said.

“In a way, it’s a very free and open society with lots of creativity,” Fukuyama noted. “You can criticize the government. I actually think [Vladimir] Putin’s invasion of Ukraine has stimulated Ukrainian nationalism — I think it made citizens realize that they actually do have something to lose.”

Fukuyama has been interested in Ukraine for a while now — he’s visited the country six times over the past five years. During his most recent trip in November 2019, he taught a crash-course in policymaking to 50 of Ukraine’s members of parliament. With an average age of 41, it’s the country’s youngest parliament ever elected, and many of the newest members have no previous political experience.

He described his time with the young Ukraianian members as inspiring, adding that they want to see a genuine democracy, and to eliminate corruption in their country.

“It does seem to me that we who live in democracies owe it to the people of Ukraine to support them,” Fukuyama said. “Because if they fail, it’s going to have repercussions way beyond Ukraine.”

The Elgin Heinz Outstanding Teacher Award recognizes exceptional teachers who further mutual understanding between Americans and Japanese. EngageAsia administers the Elgin Heinz Outstanding Teacher Award, which is funded by the United States-Japan Foundation. The 2019 Award focused on the humanities and the 2020 Award will focus on Japanese language. It is named in honor of Elgin Heinz for his commitment to educating students about Asia as well as for the inspiration he has provided to the field of pre-collegiate education.

“Waka walks in the footsteps of Elgin Heinz as a key leader in educating the next generation about the U.S.–Japan relationship,” stated David Janes, Chair of the Board, EngageAsia. Heinz was born in China in 1913 and taught in the San Francisco Unified School District for 40 years. Challenging Americans’ lack of knowledge about Asia was central to Elgin’s life’s work. Janes has overseen the Elgin Heinz Outstanding Teacher Award since its inception in 2001. Daniel Tani, Director of Foundation Grants at the U.S.-Japan Foundation, and Janes formally presented the award to Brown.

In addition to teaching Stanford e-Japan for the last five years, Brown previously served as instructor for SPICE’s Reischauer Scholars Program (RSP). The RSP is an online course that introduces Japanese society and culture and U.S.–Japan relations to high school students in the United States. Current RSP Instructor and Manager Naomi Funahashi is a 2017 Elgin Heinz Outstanding Teacher Award recipient.

Prior to joining SPICE, Brown taught Japanese language at Silver Creek High School in San Jose and served as a Coordinator for International Relations (CIR) on the Japan Exchange and Teaching (JET) Program. Brown obtained both her undergraduate and graduate degrees from Stanford University.

In her acceptance speech, Waka noted: “As a Japanese American growing up in Kansas in the 1970s and 80s, and then as a Japanese American woman working in Japan, I’ve felt the need and immediacy for fostering cross-cultural understanding for my entire life. I feel extremely fortunate that I am able to work toward this goal through my professional work. My students and their knowledge and passion humble me. I am constantly in awe of them and their accomplishments. It is a true honor to receive the Elgin Heinz Award, and I am grateful for the opportunity to use these funds to foster connections between the future leaders in U.S.–Japan relations.”

Through Stanford e-Japan, Brown has engaged Japanese high school students from throughout Japan in an intensive study of U.S. society and culture. Since its first session in 2015, over 200 Japanese students have successfully completed the course. Some of her students have matriculated to universities in the United States.

In a very meaningful moment of the ceremony, Ryoga Umezawa, one of Brown’s former Stanford e-Japan students and now a university student at the Minerva Schools at KGI in San Francisco, expressed his gratitude to Brown, noting that the online format of Stanford e-Japan eased his transition to the online format of his university studies and also noted that the knowledge he gained from Stanford e-Japan has been invaluable to his transition to life in the United States.

The ceremony ended with a duet by Norman Masuda, an inaugural recipient of the Elgin Heinz Outstanding Teacher Award in 2002 (Japanese language category), and Irene Nakasone, instructor of kutu (Okinawan koto). Nakasone played the kutu and Masuda, the sanshin (Okinawan shamisen). They performed “Akanma Bushi” (red horse folk song), which was symbolic to the occasion as it is a congratulatory classical piece from the Yaeyama Islands, Okinawa Prefecture.

Irene Nakasone and Norman Masuda play a duet at the 2019 Elgin Heinz Outstanding Teacher Award ceremony.
