Title Slide for talk by Giovanni Ramos

Join the Tech Impact and Policy Center on March 3rd from 12PM–1PM Pacific for a seminar with Giovanni Ramos.

Stanford affiliates are invited to join us at 11:40 AM for lunch, prior to the seminar.  The Winter Seminar Series continues through March; see our Winter Seminar Series page for speakers and topics. Sign up for our newsletter for announcements. 

About the Seminar:

Digital mental health interventions (DMHIs) hold promise to advance mental health equity by addressing provider shortages, reaching individuals who might not seek services in traditional healthcare settings, and making evidence-based treatments available 24/7. However, DMHI science to date has rarely involved members of historically marginalized groups in the development, testing, or implementation of these digital tools. Therefore, without careful consideration, DMHIs can perpetuate, or even worse, create new inequities in mental health. This seminar explores the state of the science in DMHIs, with an emphasis on diversity, equity, and inclusion (DEI) principles. First, with a review the current literature to determine how well DMHIs adhere to DEI principles and the current evidence (or lack thereof) supporting their effectiveness and implementation for marginalized groups. Then, a discussion of how these findings inspired the creation of Mind-Us, a DMHI for individuals who experience elevated levels of discrimination. Concluding with findings from work testing and refining new low-intensity implementation strategies to promote uptake, engagement, and retention in self-guided DMHIs for marginalized groups.

About the Speaker:

Dr. Giovanni Ramos is an Assistant Professor in the Psychology Department at the University of California, Berkeley, where he directs the Mental Health Equity in Access and Treatment (M-HEAT) Lab. His research aims to advance mental health equity among racially and ethnically minoritized populations. To achieve this goal, his work concentrates on three interconnected areas: 1) identifying risk and resilience factors that influence the mental health of marginalized groups, 2) enhancing the cultural and contextual fit of mental health treatments through data-driven cultural adaptations and implementation strategies, and 3) using digital tools to increase the accessibility of mental health services. Dr. Ramos earned his PhD in clinical psychology from the University of California, Los Angeles, and completed postdoctoral training at the University of California, Irvine, and the University of California, San Francisco.

Title slide for talk by Robin Nabi

Join the Tech Impact and Policy Center on February 17th from 12PM–1PM Pacific for a seminar with Robin Nabi.

Stanford affiliates are invited to join us at 11:40 AM for lunch, prior to the seminar.  The Winter Seminar Series continues through March; see our Winter Seminar Series page for speakers and topics. Sign up for our newsletter for announcements. 

About the Seminar:

Extensive attention has been paid to the potential harms of media consumption generally, and social media use in particular, with relatively little consideration given to the potential psychological benefits of media use. This talk will address why this bias exists and its potential for unintended negative consequences.  Evidence of how self-selected and prescribed digital media content can support desirable outcomes, including reduced stress and procrastination, increased goal motivation and pursuit, and increased empathy and relational satisfaction, will be shared to highlight the need for better understanding of how to empower users to make media choices that can support their psychological well-being.

About the Speaker:

Robin L. Nabi is a Professor of Communication at the University of California, Santa Barbara. With degrees from Harvard and the University of Pennsylvania, she has published over 100 journal articles and book chapters investigating the effects of media use on emotional experiences, decision-making, and well-being.  She is the co-editor of two volumes: The SAGE Handbook of Media Processes and Effects and Emotions in the Digital World (Oxford University Press). She is a Fellow of the International Communication Association, and her research has been featured in numerous media outlets, including the New York Times, the Los Angeles Times, USA Today, NPR, CBC/Radio-Canada, and the Harvard Business Review.

About the event: Michael F. Joseph will present the theory and experimental chapter from his forthcoming book (Cambridge May, 2026), The Origins of Great Power Rivalries. In it, he advances a comprehensive rationalist theory of how great powers assess emerging threats; why enduring great power rivalries unfold through either delayed competition, or delayed peace; and how diplomacy functions when rising powers emerge on the scene. In an important departure from traditional realist theory, Joseph argues that countries are motivated by distinct principles - normative values that shape foreign policy beyond simple security concerns. He then integrates these complex motives into a formal model of great power rivalry to explain how rational states draw qualitative inferences about rivals' intentions by examining the historical context of their demands, not just military capabilities. Empirically, he shows that his predictions about the instances and timing of competition better fit great power rivalry cases than leading rationalist and psychological alternatives via a medium-n analysis of great power rivalries since 1850. He illuminates British reactions to Stalin at the beginning of the Cold War via an in depth historical analysis. He animates a theoretically sophisticated defense of America's approach to China in the post-Cold War era with 100s of Washington-insider interviews and a novel analysis of recently declassified estimates. He demonstrates that real life intelligence analysts integrate diplomacy, historical context and an appreciation of strategic incentives as his theory expects, by embedding a survey experiment into an intelligence simulation given to 100s of real-life intelligence analysts and national security professionals from the CIA, State Department, DOD and elsewhere. Michael is known for "hot takes," and all information he presents is his personal opinion and does not reflect the position of any government and should not be taken seriously be anyone.

About the speaker: Michael F. Joseph is an Assistant Professor at UCSD. He harnesses a decade of foreign policy experience and sophisticated research skills to resolve modern national security problems of great power competition, and technology in the intelligence community. His research was recognized with APSA's 2021 Formal Theory Section Award, the 2023 Palmer Prize, and a $450,000 NSF Grant for National Security Preparedness, among other accolades. His book is forthcoming with Cambridge University Press. His articles are published or forthcoming in the APSR (x3), JOP (x2), IO, and other journals. Policy insights from this research have attracted policy-maker attention in DC, and appear in the Washington Post, War on the Rocks, and other leading outlets.

Global, Regional, and Country Level Prevalence of Young Children Exposed to Risks of Poor Development in Low and Middle Income Countries: An Update

 

Quantifying the prevalence of young children exposed to risks of poor development is imperative for understanding the challenges of reducing those risks, developing and evaluating evidence-based early childhood development policy interventions, and assessing progress in eliminating the risks imposed upon young children during their most critical developmental period. We published estimates on the prevalence of young children exposed to stunting and extreme poverty at the global, regional, and country levels in 2017. Since new data have been released and a new definition of extreme poverty has been proposed, we updated our 2017 study with a focus on the progress in reducing the prevalence of risk exposure at different levels since 2000. For countries with other risk factors available in their micro-level data, we added them to the composite measure and assessed the levels and trends of sociodemographic disparities in young children’s risk exposure.

This talk examines how age and generational differences shape smartphone adoption patterns in South Korea, one of the world's most rapidly aging societies. Using discrete-time hazard models, the analysis investigates whether digital divides reflect temporary life stage effects or persistent generational differences that accompany cohorts throughout their lives. Preliminary results reveal striking heterogeneity both across and within age cohorts, suggesting that neither age nor cohort membership alone fully explains adoption patterns. Motivated by these findings, the talk concludes by introducing an age-period-cohort framework designed to separate the distinct effects of aging, different formative experiences (cohort effect), and changing environment (period effect) on technology adoption.

About the event: This project presents the concept of wartime access—decisions by states to let other states fight wars from inside their borders—and establishes its centrality to U.S. power projection. Although permissive wartime access has been a defining feature of the post-1945 world, states do not always let the United States military in. States sometimes restrict access sharply or deny it altogether. This project asks, why do states sometimes grant, sometimes restrict, and sometimes deny wartime access? It argues that the general trend of permission is attributable to states’ expectations that they will derive security benefits from the United States in exchange for granting access, and that the United States will protect them from retaliation by the target and help them manage any spillover from the war. While security factors tend to point states towards granting access, states tend to deny or heavily restrict access when the domestic political costs of open alignment with the United States are prohibitively high. The study develops a new dataset of 85 partner access decisions across eleven U.S.-led wars since 1945 and conducts paired comparisons of wartime access decisions within each war. The project concludes with a discussion of policy implications, with particular attention to wartime access in the context of a hypothetical U.S. effort to defend Taiwan.

Yuli Xu Poster

Continuity of medical care is widely observed, but it is often difficult to disentangle patients’ intrinsic preferences from system-imposed switching costs. In this webinar, Dr. Yuli Xu discusses a study that uses the Chinese healthcare setting, where patients can freely choose physicians at each visit and flexibly switch across hospitals and departments, to isolate patients’ value of physician continuity.

Estimating a discrete choice model, the study shows that patients strongly prefer to see the same physician despite minimal institutional barriers to switching, indicating an intrinsic preference for continuity. The study also examines how physicians’ temporary leave affects patient behavior, using a stacked difference-in-differences design. A physician’s absence leads to significant reductions in patient visits, both within the physician’s department and across other departments in the same hospital, with no substitution toward other hospitals and no detectable effects on health outcomes. Patients return to their original physicians once they resume practice. Moreover, patients with more severe conditions incur higher spending when forced to see a new physician. Overall, the findings demonstrate that patients place substantial intrinsic value on physician continuity, even in a healthcare system with highly flexible provider choice.

Yuli Xu

Yuli Xu joins the Walter H. Shorenstein Asia-Pacific Research Center (APARC) as Asia Health Policy Postdoctoral Fellow for the 2025-2026 academic year. She recently obtained her Ph.D. in Economics at the University of California, San Diego. Her research focuses on Labor and Health Economics, with particular interests in how female labor force participation and fertility decisions are influenced by labor market institutions and past birth experiences. In her thesis, "Gendered Impacts of Privatization: A Life Cycle Perspective from China," she demonstrates that the reduction in public sector employment has widened the gender gap in the labor market while narrowing the gender gap in educational attainment. She also finds that this structural shift has delayed marriage among younger generations.

In another line of research, Yuli examines the effects of maternity ward overcrowding. She finds that overcrowding reduces the use of medical procedures during childbirth without negatively impacting maternal or infant health. While it has no direct effect on subsequent fertility, she shows that mothers, especially those with a college degree, are more likely to switch to another hospital for subsequent births after experiencing overcrowding. During her time at APARC, Yuli will further investigate patient-physician relationships in the Chinese healthcare system, where patients have considerable flexibility in choosing their doctors at each visit. She will explore the persistence of these relationships and examine how patients respond when their regular doctors are temporarily unavailable.

Yuli also holds a B.A. in Economics from the University of International Business and Economics in China.

Former Stanford President John Hennessy moderated a conversation about AI’s impact on the world with distinguished technology executive Craig Mundie and New York Times columnist Thomas Friedman. As AI continues its unprecedented transformation of our world, Mundie and Friedman reflected on their 25-year friendship and discussed the technological and societal trends that led them to argue, in a recent op-ed, that humanity has entered a new era of civilization. They explored the implications of this shift for daily life and geopolitics, as well as the technical and normative frameworks needed to establish trust in AI systems.
