Values And Posttraumatic Resilience: Assessing The Moderating Impact Of Cultural Context, Jeremy Brian Clift

Graduate Theses and Dissertations

People commonly experience a traumatic event during their lives, and many effectively cope with the experience, demonstrating psychological resiliency. However, this is not always the case; others may develop psychopathology in the wake of a traumatic event, such as posttraumatic stress disorder. Why might some people experience clinically significant difficulty following a traumatic event while others do not? The current study examined this question by considering the role of values—cognitive representations of motivations that guide action—and testing predictions generated from the Contextual Model of Values-Based Responding to Traumatic Experiences (Clift & Veilleux, unpublished manuscript). It was predicted that greater growth …

Drawing Conclusions: Autonomy And Mental Maps In Denmark And The Faroe Islands, Erik Steven Breidinger

Graduate Theses and Dissertations

This dissertation develops and tests a comparative heuristic device called optimal autonomy to explain when and how autonomous territories, or simply autonomies, become durable components of the global system of sovereign states. Drawing on a mixed‑methods case study of Denmark and the Faroe Islands, the study operationalizes optimal autonomy as a heuristic device using three interacting metrics: territorial delineation, national distinction, and state dependence. Using semi‑structured interviews with public officials and a mental‑mapping experiment with university students, this research shows that optimal autonomies are not made from single institutional designs but rather a dynamic equilibrium between maximal territorial delineation, medial …

I Can’T Fight This Feeling Anymore: Investigating The Influence Of Cognitive Emotion-Related Impulsivity On Behavioral Impulsivity Through The Lens Of Emotion Regulation In Daily Life, Dylan Shelton

Graduate Theses and Dissertations

Emotion-related impulsivity is a transdiagnostic risk factor that is seen across a wide range of psychiatric disorders. Traditionally, emotion-related impulsivity has been studied at the trait level, reflecting that it is something that someone has rather than something that they do. However, recent studies have highlighted the importance of viewing emotion-related impulsivity as a dynamic process that occurs in response to momentary emotional experiences. However, it is less clear about the influence of attentional and evaluative processes on downstream behavioral responses that may be aimed at rapidly regulating emotion. This study aimed to investigate emotion-related impulsivity through the lens of …

The findings indicate a high level of awareness concerning the …

Personal Goal Facilitation, Burnout And Work Engagement: The Role Of Self-Discrepancy, Jacinth Jia Xin Tan, Bek Wuay Tang

Research Collection School of Social Sciences

Employees who perceive greater personal goal facilitation through work (PGFW) experience lower burnout and higher work engagement. This research examined whether self-discrepancies and emotional experiences explain these relationships across two cross-sectional studies involving a nationally representative sample of working adults (Study 1; N = 889) and a sample of public school teachers (Study 2; N = 228) in Singapore. Participants listed personal goals and rated how much their jobs facilitated these goals, alongside measures of self-discrepancy, emotions, burnout, and engagement. Across both samples, higher PGFW predicted lower burnout and greater engagement. These associations were consistently explained by lower ideal self-discrepancy …

A 10-Minute Walk From The Mrt. But For Whom?, Paulin Tay Straughan, Yi Wen (Chen Yiwen) Tan, Wensi Lim

Research Collection School of Social Sciences

They highlighted that as people age, mobility naturally declines, adding that the convenient shorthand such as a “10-minute walk” to define accessibility is ultimately a social construct – one that must be grounded in lived realities and evidence. They noted that ageing in place is not just the ability to remain at home as one transitions into later life – it is about living in an environment that fosters attachment, continuity and well-being, which requires both the built and social environments to be supportive. Responses must be guided by solid evidence – through ongoing conversations with those whose needs we …

The Effects Of Functional Coaching On Increasing Functional Play Behaviors In Adults, Abby L. Pattengale

Theses and Dissertations

Play is a critical developmental context for children with autism spectrum disorder (ASD), supporting cognitive, social, communication, and adaptive skill development. However, many adults, specifically registered behavior technicians (RBTs), demonstrate limited engagement in developmentally appropriate play behaviors, which can restrict the quality of play-based interventions, which are essential for effective treatment. However, little research has examined interventions designed to improve adult play behaviors. The purpose of this study was to evaluate the effects of functional coaching on increasing adult functional play behaviors during therapy sessions with children diagnosed with ASD. Two RBTs participated in the study, and two children receiving …

The Mental Health Of Athletes: Channeling Frustration, Aggression, Internal/External Behaviors In The Real World To Improve Performance, Jabari Johnson

Dissertations

This qualitative study examined how college athletes, 18 years and older, experience and interpret internalizing behaviors and externalizing behaviors within contact and non-contact sports, and how those experiences are shaped by gender, racial/ethnic background, and socioeconomic status. The study addressed a gap in the literature by centering athletes’ own perspectives on how emotions, coping, identity, and performance intersect within collegiate sport contexts. A purposive sample of 12 athletes completed a demographic questionnaire and participated in semi-structured interviews conducted in person between December 2025 and February 2026. Interview transcripts were deidentified and analyzed using reflexive thematic analysis following Braun and Clarke’s …

Examining The Relationship Between Trauma-Informed Safety Drill Practices And School-Level Chronic Absenteeism In Maine Secondary Schools, Tina Nightingale

Dissertations

School safety practices can influence students' perceptions of safety, emotional well-being, and engagement in the educational environment; however, limited research has examined whether trauma-informed safety drill practices are associated with measurable educational outcomes. The purpose of this quantitative, non-experimental, correlational study was to examine the relationship between trauma-informed safety drill practices and school-level chronic absenteeism in Maine middle and high schools. Guided by trauma-informed care, adolescent neurodevelopment, and Protection Motivation Theory, the study investigated whether higher levels of trauma-informed implementation of safety drills, as measured by the Trauma-Informed Safety Drill Practices Index (TISDPI), were associated with lower rates of chronic …

Strengthening The Shield: Exploring Post-Traumatic Growth In Law Enforcement, Aaleiyah C. Spaulding

Dissertations

Law enforcement officers are routinely exposed to traumatic incidents that can lead to psychological distress, including posttraumatic stress disorder (PTSD). However, emerging literature highlights the potential for posttraumatic growth (PTG), a positive psychological change following adversity. This study examined the prevalence and predictors of PTG in a sample of 33 police officers from a Midwestern department. Using validated self-report measures, the study assessed the role of trauma exposure, cognitive restructuring of core beliefs, and perceived organizational culture, particularly supervisor support. Results indicated that both internal (core belief reflection) and external (supervisory support) factors significantly predicted PTG. Additionally, involvement in a …

In phase two, semi-structured interviews were conducted via Zoom to explore the library's role in providing access to these resources. …

Do I Fit In Here? How Immigrants’ Endorsement Of Social Markers Is Related To Their Wellbeing In Three Migrant Receiving Societies, Justine Dandy, Chan Hoong Leong, Adam Komisarof, Travis Lim, Krystal Perkins

Research outputs 2022 to 2026

Social markers of acceptance are the attributes seen as important for immigrants to achieve or display in order to be accepted similarly to a local-born citizen. In research on constructions of national identity, factor analysis reveals a culture-specific, two-factor structure akin to the ethnic–civic distinction observed. In this paper, we extend this work by examining the relationship between social markers of acceptance and immigrants’ well-being in three national contexts: Australia, Japan, and the U.S. Specifically, in study 1 we examined the factor structure of social markers in non-immigrant samples in each context (Australia, n = 1357; Japan, n = 2000; …

Modeling And Forecasting Intraday Spot Volatility, Adam Clements, Daniel P. A. Preve

Research Collection School Of Economics

We propose a multiple-equation regression-based method for modeling and forecasting intraday spot volatility. In this approach, intraday intervals are treated as individual time series, deviating from the common practice of treating the data as one continuous sample. Our empirical study, which spans more than two decades and encompasses six US blue-chip stocks, employs the recent OK volatility estimator developed by Li, Wang, and Zhang (2024) to expose the dynamics of latent intraday spot volatility over time. We demonstrate that the proposed method effectively captures the intricate dynamics of intraday spot volatility and find strong evidence that it outperforms a competing …

Navigating Unemployment Without Unemployment Insurance: Evidence From Singapore, Kim, Lanjie Wang

Research Collection School Of Economics

This study investigates the short-term impacts of unemployment among older workers (aged 50–62) in Singapore, a setting with-out public unemployment insurance. Using monthly panel data from the Singapore Life Panel, we analyse dynamic effects onmajor life outcomes such as income, spending, health, and subjective wellbeing over 2 years post-unemployment. Our findingsreveal substantial initial earnings losses with incomplete recovery: income remains 50.7% below pre-unemployment levels after24 months. Despite this persistent income gap, total household expenditure declines by 9.8% on average over 2 years (rangingfrom 7% to 16% across months). The implied two-year marginal propensity to consume is about 0.182, smaller than …

How Do Sectoral Shocks Shape Future Gdp?, Paul Ho, Danial Lashkari, Pierre-Daniel Sarte

Research Collection School Of Economics

A production sector’s size, as measured by its Domar weight, captures the contemporaneous aggregate effect of its productivity shocks. Any future aggregate effects, however, depend on that sector’s participation in the investment network. We derive a dynamic generalization of Hulten’s theorem in an environment with intermediate-input and investment networks. This generalization, implied by production efficiency alone, decomposes each sector’s Domar weight into an impact and a propagation component. The relative size of these components then determines how persistent the aggregate effects of sectoral shocks are, but cannot be known absent information on the economy’s production structure. We show in a …

The Effect Of Vaccine Mandates On Disease Spread: Evidence From College Covid-19 Mandates, Riley K. Acton, Wenjia Cao, Emily E. Cook, Scott A. Imberman, Michael F. Lovenheim

Research Collection School Of Economics

Nearly 700 4-year U.S. colleges mandated students receive COVID-19 vaccinations in fall 2021. Using data on college policies and county health, we estimate how mandates affect surrounding communities. Event studies from August to November 2021 show that mandates covering all colleges in a county reduced COVID-19 deaths by 5.6 per 100,000 persons, a 4.6% reduction in the U.S. total during this period. Mandates reduced COVID cases by 504 and ICU admissions by 16.2 per 100,000, though we see no statistically significant impact on hospitalizations. Impacts are larger in counties with larger college populations and low estimated ex-ante student vaccination rates.

The Unintended Consequences Of International Student Shortage: Evidence From South Korea, Chung-Yoon Choi, Syngjoo Choi, Seonghoon Kim, Jongkwan Lee

Research Collection School Of Economics

We study the role of international students in the higher education sector and the local economy by exploiting a policy reform in South Korea that restricted the admission of foreign students to local universities. By comparing the pre- and post-reform differences across universities with different pre-reform shares of international student enrollment, we show that an international student shortage resulting from this policy reform significantly worsened the financial outcomes of universities and consequently led to reduced investment in their students. We also document that a reduction in the number of international students in local areas decreased native employment, mainly in low-skilled …

Smart-Twin: Systematic Modeling And Real-Time Transportation With Digital Twins, Hovannes Kulhandjian

Mineta Transportation Institute

Urban transportation networks are increasingly affected by everyday congestion, non-recurring disruptions, and limited real-time visibility into what is happening on the road. Transportation agencies require advanced tools that support faster, proactive management and data-driven infrastructure decisions rather than passive monitoring. This report presents SMART-TWIN, an Artificial Intelligence (AI)–driven Digital Twin framework designed for real-time traffic operations, disruption detection, and performance-based decision-making support. The SMART-TWIN architecture integrates microscopic traffic simulation (detailed traffic modeling), long-horizon synthetic demand generation simulating real travel patterns, supervised machine learning, and performance analysis within a unified and reproducible workflow. A corridor-scale Digital Twin was developed for the …

Patient Perspectives On Psychiatric Polygenic Risk Scores In Reproductive Decision-Making And Polygenic Embryo Screening., Lauren A Ginn, Amanda R Merner, Page M Trotter, Kaitlynn P Craig, Abigail C Martinez, Ana Lucía Battaglino, Dorit Barlevy, Daphne M Ayton, Takahiro Soda, Eric A Storch, Gabriel Lázaro-Muñoz, Stacey Pereira

Center for Medical Ethics and Health Policy Staff Publications

Polygenic risk scores (PRS) estimate individuals' genetic risk for developing multifactorial conditions. Recent genome-wide association studies have enabled development of psychiatric PRS, which hold potential to streamline diagnosis and treatment of psychiatric conditions. As individuals with mental illness often identify concern about passing on psychiatric conditions as a key factor in family planning, some may also seek to use psychiatric PRS in reproductive decisions like childbearing or embryo selection for in vitro fertilization. Despite calls for increased regulation, there remains no clinical consensus on the utility of psychiatric PRS in reproductive contexts. Therefore, we conducted semi-structured interviews of adults with …

An Integrated Cardiometabolic Genetic Testing Program In A Predominantly Hispanic Population Within A Community Setting, Bo Yuan, Layla A Abushamat, Stacey Pereira, Surya Narayan Mulukutla, Grace E Tietz, Eric Venner, Sara E Kalla, Breanna Lee, Donna Muzny, Ginger Metcalf, Mullai Murugan, Sarah H Elsea, Senkottuvelan Kadirvel, Lele Li, Joshi Stephen, Shengfeng Xu, Victoria Yi, Monica Sulit, Christie L Kovar, Kimberly Walker, Marie-Claude Gingras, Jianhong Hu, Fei Yan, Taeko Gerber, Viktoriya Korchina, C Michael Fordis, Ruchi Gaba, Mahesh Changlani, Herschl Silberman, Hadley Stevens Smith, Christine M Eng, Jennifer E Posey, Clarisa Medina, Lisa R Treviño, Christie M Ballantyne, Richard A Gibbs, Ashok Balasubramanyam

Center for Medical Ethics and Health Policy Staff Publications

Purpose: This study aimed to apply cardiometabolic genetic testing in a community setting with a predominantly Hispanic population and assess feasibility and perspectives toward genetic testing.

Methods: A genome-sequencing-based genetic panel for cardiometabolic disorders (177 genes related to monogenic conditions, 2 LPA risk alleles, 2 pharmacogenomic loci, and ancestry-adjusted polygenic risk scores for type 2 diabetes and coronary artery disease) was deployed in community cardiology and endocrinology clinics in South Texas. A survey on perceptions toward genetic testing was administered after return of results.

Results: Testing was completed for 776 patients (18-92 years old, 92% Hispanic). 26 patients (3.4%) were …

Routes To Sustainable Goods Movement: How Local And Regional Governmental Agencies Can Plan For The Sustainable Freight System Of The Future, Serena E. Alexander, Avante Grady

Mineta Transportation Institute

Freight transportation plays a critical role in supporting economic activity and everyday consumption across metropolitan regions, but growing freight demand continues to increase congestion, infrastructure strain, greenhouse gas emissions, air pollution, and safety risks. These impacts often disproportionately affect low-income and environmentally burdened communities. This report examines how metropolitan regions across the United States are planning for sustainable freight transportation through content analysis of freight and goods movement plans and interviews with freight planning professionals. The study analyzes plans from eight major metropolitan regions to identify common freight planning strategies, implementation approaches, opportunities, and barriers related to sustainability, resilience, and …

Preparing Today’S Workforce For Tomorrow’S Autonomous Transportation: Bridging Electrical And Civil Engineering Disciplines, Masoud Ghodrat Abadi, Rohollah Moghadam

Mineta Transportation Institute

Autonomous vehicles (AVs) are expected to transform transportation systems and reshape workforce needs across engineering and related fields. Although existing AV workforce development efforts often emphasize electrical engineering, computer science, and mechanical engineering, transportation engineering remains underrepresented despite its importance to infrastructure, traffic operations, safety, and mobility integration. This study addresses that gap through the development, implementation, and evaluation of an interdisciplinary certificate program, Workforce for Autonomous Vehicle Engineering (WAVE), at California State University, Sacramento. The program was designed to bridge transportation engineering and electrical engineering through a two-step curriculum model consisting of theoretical educational modules and hands-on laboratory activities. …

Mitigating Negative Consequences Of New Urban Growth In Disadvantaged Communities, Shishir Mathur, Christopher E. Ferrell, Cindy Adrian

Mineta Transportation Institute

New housing and development in California are often planned in communities that already face economic hardship, environmental burdens, and limited access to reliable transportation. Recent research finds specifically that in the San Francisco (S.F.) Bay Area and Southern California (SoCal) metropolitan regions, there is a high propensity to plan new urban development in socially, economically, and environmentally disadvantaged communities (DACs) with poor transit accessibility and limited personal mobility. This project first reviews the literature to identify potential unintended negative impacts of high concentrations of new urban growth in DACs across social, economic, educational, environmental, and transportation dimensions. It then identifies …

The Power And Peril Of Awe In Leadership: Transforming Follower Identity And Behavior, Jack Mcguire, Daniel Mcallister, Jochen Menges, David De Cremer

Research Collection Lee Kong Chian School Of Business

Awe is a profound emotion that has captured significant attention within psychological research. While the potential for leaders to inspire awe in followers has received some recognition, systematic research on the nature and effects of awe in leadership—and within organizational contexts more broadly—remains limited. In this article, we offer a conceptual framework that explains the multifaceted and transformative nature of leadership through the power of awe. Specifically, we identify four leader behaviors—charismatic leadership tactics, exceptional performance, problem reframing, and self-sacrificial behavior—that elicit awe among followers. We further propose three variants of awe-inspiring leaders, describing how variation in a leader’s self-construal …

Online Planning Of Power Flows For Power Systems Against Bushfires Using Spatial Context, Jianyu Xu, Qiuzhuang Sun, Yang Yang, Huadong Mo, Daoyi Dong

Research Collection College of Integrative Studies

A power station or transmission line can be affected due to bushfires, increasing operation costs. We study a fundamental but challenging problem of planning the optimal power flow (OPF) for power systems under bushfires. We develop a model to capture the stochastic nature of bushfire spread based on Moore’s neighborhood model and propose an online optimization modeling framework to sequentially plan power flows in the electricity network. Our framework assumes that bushfire spread is non-stationary over time and that the spread and containment probabilities are unknown. To address these challenges, we develop a contextual online learning algorithm that treats the …

Locally Robust Implementation Of Efficient Bilateral Trade With Correlated Beliefs, Takashi Kunimoto, Cuiling Zhang

Research Collection School Of Economics

We identify the ex ante welfare (EAW) condition as a necessary requirement to implement ex post efficient bilateral trade in any finite type space with interdependent values and correlated beliefs. As these finite settings become finer to approximate a continuous type space, we derive a limit EAW condition by taking the EAW condition in finite settings to its limit. We show that this limit condition trivially holds in the benchmark continuous setting admitting a full-support density function. We then insist on locally robust implementation by requiring efficient trade to be implemented uniformly across all finite type spaces that approximate the …

Occupation Ladders Over The Business Cycle, Ismail Baydur, Toshihiko Mukoyama

Research Collection School Of Economics

This paper studies occupational mobility over the business cycle. We divide occupations into two broad groups, “attractive” and “nonattractive”, where we label an occupation attractive if the total net inflow into this occupation through job-to-job transition is positive. We measure total net inflows into both occupation groups. We measure these inflows separately for job-to-job transitions and transitions from unemployment to employment. We find that the net inflow from nonattractive to attractive occupations through job-to-job transitions slows during recessions. The net inflow through transitions from unemployment has a similar cyclicality. This finding suggests a novel cost of recession: during recessions, workers …

Sustainable Rural Development Under Ecological Civilization: Two Mountains Theory, “Green Rural Revival”, And Post-Productivist Transition In Zhejiang, Qian Forrest Zhang, Jianzhang Luo, Li Zhou

Research Collection School of Social Sciences

Existing studies of China’s overarching ideological framework for national development, “Ecological Civilization”, have focused narrowly on environmental governance; how it reshapes sustainable rural development remains underexplored. This paper pursues two analytically distinct tasks. First, it reconstructs the policy history of how President Xi Jinping’s “Two Mountains” theory was incorporated into the Eco-civilization framework and how Zhejiang Province’s “Green Rural Revival” (GRR) program, as a lived example of Eco-civilization, was elevated as the national template for rural development in 2024. Second, drawing on three cases from a sample of 21 villages in Zhejiang, it identifies three core practices of GRR and …

Global Prevalence Of Internet Gaming Disorder: An Umbrella Review Of Meta-Analytic Evidence And Implications For Child And Adolescent Psychiatry, Elisabeth C. S. Poon, Xun Ci Soh, Trina J. H. Poh, Andre C. S. Tan, Andree Hartanto

Research Collection School of Social Sciences

Background/Objectives: Internet gaming has become a widespread global activity, raising concerns about the prevalence of Internet Gaming Disorder (IGD). However, existing meta-analyses report highly variable prevalence estimates. This umbrella review aims to clarify the prevalence and variability of IGD by synthesizing evidence from meta-analyses to provide a comprehensive overview of IGD prevalence across populations, age groups, and regions. Methods: Following PRISMA guidelines, systematic searches were carried out across five published literature databases and two supplementary search sources. Title and abstract screening, followed by full-text eligibility assessment, were conducted independently by three authors. The same three authors then performed data extraction …
