Psychological Architecture: Evaluating The "Greenhouse Model" As A Structural Standard For Lgbtq+ Well-Being, Ava Lee

University Honors Theses

Traditional LGBTQ+ mental health frameworks often conceptualize psychological safety as a matter of individual endurance. This paper critiques this focus on adaptive resilience, which systematically shifts responsibility from institutions to individuals. To counter this, the study introduces "Psychological Architecture," a framework viewing social environments as constructed infrastructures that can either support or undermine queer well-being. The model contrasts performative "Glasshouses," which prioritize visibility over safety, with engineered "Greenhouses" that nurture sustainable safety through three sequential pillars: Authentic Representation (walls), Emotional Validation (insulation), and Vocal Activism (ventilation).

Grounded in the findings of a 2024 qualitative pilot study of a queer roller …

Legends, Lies, & Rewritten Lives: After The Little Bighorn: Forgotten Struggles Of Those Who Walked Away, 2nd Edition, Thomas B. Davidson

DU Textbooks

This Story surrounds an event that occurred one summer on June 25, 1876, along the banks of the Little Bighorn River in what is now the state of Montana. Seen from a 21st century perch, it is a story of a collision between two very different civilizations or empires. Both empire’s military fought in the manner of their society. This narrative will attempt to balance the believable truth of what happened in that contest between the military representatives of both societies while also trying to tell an engaging story, without drifting into naked partisanship, purple prose, or sensationalism. The narrative …

Essays On The Economics Of Aging: Structural And Machine Learning Approaches, Alexander S. Kwon

Dissertations, Theses, and Capstone Projects

Population aging has made the study of older workers’ economic behavior increasingly important for understanding labor markets, retirement systems, and public policy. In many advanced economies, rising old-age dependency ratios have increased the need to understand labor-supply, retirement, and savings decisions later in life (OECD, 2025). In the United States, these issues are especially important because Social Security faces long-run financing pressure, with the Old-Age and Survivors Insurance Trust Fund projected to be depleted around 2033 (U.S. Social Security Administration, Office of the Chief Actuary, 2025). Longer life expectancy increases the expected length of retirement and raises the fiscal importance …

Mandates, Markets, And Megawatts: An Empirical Analysis Of The Causal Effects Of State-Level Energy Storage Mandates On Utility-Scale Battery Storage Deployment In The United States, Bill Zheng

Quantitative Social Science Undergraduate Senior Theses

Utility-scale battery storage is accelerating at an unprecedented pace as the world increasingly relies on renewable energies to power grids. Demand for data centers has produced record-high electricity demand, and utility-scale batteries are becoming crucial in supporting the grid and the variability of renewables. As a result, analysis on the efficacy of policy drivers of battery storage will provide the field with a roadmap for the most impactful policy solutions to spur battery storage deployment. This paper estimates the effect of state battery storage mandates on cumulative installed battery capacity using a staggered difference-in-differences (DiD) design following Callaway and Sant’Anna …

How Much Should A Conversational Recommender System Converse?, Akshit Kumar, Vahideh Manshadi, Akhilesh Tumu

Cowles Foundation Discussion Papers

Conversational recommender systems powered by generative AI can enhance personalization by facilitating information elicitation through follow-up questions. However, engaging in these conversations imposes a communication cost on users. As platforms with different objectives and monetization models deploy these systems, a central question is: how does the platform’s objective and sellers’ strategic response shape the design of these systems in terms of their elicitation strategy? We develop a parsimonious model of conversational elicitation in which interaction generates noisy preference information and imposes a communication cost borne by the user. A user-welfare-maximizing platform elicits more information when accurate niche matching yields large …

Crime, Economic Forces And Trucks Crossings In The Us–Mexico Border Region, René Cabral, André Varella Mollick, Eduardo Saucedo

School of Economics and Finance Faculty Publications

We investigate northbound loaded truck crossings from Mexico to the United States between 2015 and 2023. A weaker peso, exports and US industrial production positively affect loaded containers. Truck robberies at the municipal level show no statistically significant relationship with truck loadings, whereas truck robberies at the national and state levels present a negative, persistent association. Results suggest that Mexico–US trade would benefit from lower average Mexican crime rates. In addition to comparing Texas with other border states, this study documents the role of crime specific to the transportation sector as a negative relevant driver of truck crossings to the …

Fiscal And Monetary Policies For Inclusive Growth In Developing And Emerging Markets, Collins Anosike

Journal of Global Awareness

The study examined the effects of monetary and fiscal policies in attaining inclusive growth for some developing countries and emerging markets. The study selected 20 countries and grouped them into group one and group two. The study is unique because it captures a broader range of countries compared to previous studies and shows their effect on economic growth. We use panel data and employ OLS regression and Johansen cointegration. We examine how each variable, general government expenditure, gross national expenditure, total revenue, official exchange rate, broad money, and deposit interest rate, affects the dependent variable (real GDP) from 1980 to …

Spatial Analysis Of Maize Yields And Household Dietary Diversity In Sub-Saharan Africa: Causal Evidence From A Machine Learning Instrument, Addi Joof

Master's Theses

MAIZE YIELDS AND HOUSEHOLD DIETARY DIVERSITY IN SUB-SAHARAN AFRICA: EVIDENCE ON THE CAUSAL EFFECT FROM A MACHINE LEARNING INSTRUMENT

Addi Joof, University of San Francisco, May 2026

This paper provides estimates of the effect of maize yield on household dietary diversity across seven Sub-Saharan African countries, using data from 36,474 maize-growing households in the Living Standards Measurement Study Integrated Surveys on Agriculture (LSMS-ISA) panels for the period 2008--2021. OLS estimates which include district and country-by-wave fixed effects yield a positive and significant coefficient of 0.070 (SE = 0.006, p < 0.001), implying that a 10 percent increase in maize yield raises the Household Dietary Diversity Score (HDDS) by approximately 0.007 food groups. Because self-reported yields are subject to classical measurement error and unobserved household characteristics confound the OLS estimate, we construct an instrumental variable using a Random Forest model trained on satellite-derived agro-environmental features including the Enhanced Vegetation Index, Normalized Difference Vegetation Index, Growing Degree Days, precipitation, and soil moisture obtained from Google Earth Engine at the GPS-coordinate-by-year level. Our preferred 2SLS specification, which adds region fixed effects to absorb persistent sub-national geographic variation, returns a positive point estimate of 0.217 (SE = 0.206; 95% CI: -0.19 to +0.63, p = 0.294) larger than OLS and consistent with downward attenuation bias, but imprecisely estimated and statistically indistinguishable from zero at conventional levels. We interpret the OLS estimate of 0.070 as a credible lower bound on the true effect, with the IV evidence pointing to a moderately larger but uncertain magnitude. Heterogeneity analysis reveals a declining gradient across consumption quintiles the effect is strongest among the poorest households (Q1: 0.055, p < 0.01) and diminishes with wealth (Q5: 0.015, not significant) while showing no gradient across market-integration levels. These patterns are consistent with own-consumption, rather than market income from surplus sales, as the primary pathway from yield to dietary diversity. OLS estimates are positive and significant in five of six estimable countries. The findings suggest that maize yield improvements can serve as a nutrition co-investment, particularly for subsistence-oriented smallholders, though the available data do not permit a sharp causal quantification of the effect size.

The Effects Of War Exposure On Psychological Well-Being And Social Preferences, Jacinta B. Duncan

Master's Theses

Using original survey and experimental data collected in Ukraine in 2023 and 2024, this paper estimates the causal impact of exposure to war-related violence on psychological outcomes, social preferences, and cognitive functioning. I combine a disaggregated war experience index with two incentivized economic experiments - a modified Dictator Game and an Emotional Stroop Test - and exploit randomized variation in task order as a priming treatment to establish causal identification. I find that war exposure has clear and consistently negative effects on psychological well-being, with direct personal experience producing the largest reduction in DASS well-being (β=−0.338 SD, p < 0.01), and that these effects are broadly distributed across demographic groups - though women report disproportionately higher psychological distress even at low levels of exposure. Social support emerges as the most effective buffer against war-related psychological harm, nearly eliminating the well-being gap between high- and low-exposure individuals, while economic hardship compounds distress and drives passive coping responses. In contrast, war exposure has limited and context-specific effects on social preferences: property loss and direct exposure increase prosocial behavior, but only when sharing is costless, consistent with solidarity norms operating within binding resource constraints. Cognitive task performance is largely unaffected by war exposure or emotional priming, with education emerging as the dominant predictor of Stroop performance across all specifications. Taken together, these findings support targeted, gender-sensitive mental health interventions and community-based support programs as high-leverage instruments for mitigating the long-term human costs of conflict.

Crop Yield Shocks And Conflict In Sub-Saharan Africa: Subnational Evidence From Satellite-Based Yield Predictions, Benson I. Adomako

Master's Theses

This paper examines whether crop yields affect violent conflict at the subnational level across seven Sub-Saharan African countries: Burkina Faso, Ethiopia, Mali, Malawi, Niger, Nigeria, and Tanzania, over the period 2010 to 2024. A central identification challenge is that observed yields are endogenous to conflict: armed violence disrupts planting, cultivation, and harvest. To address this, I train a machine learning model on observed maize yield and satellite and environmental features to generate predicted yields for 1,338 second-level administrative districts annually. These predictions serve as the key regressor in a two-way fixed-effects panel with district and year fixed effects. I find …

The Evolution Of Economic Rhetoric And Its Correlation With The Marginalization Of Ethics In Economics, Mi Phan, Rhiannon Scharnhorst

Undergraduate Research (Journal)

Economic discourse has undergone a profound transformation from its moral-philosophical origins to contemporary mathematical formalism. This study examines whether the shift toward formalized economic writing resulted in the marginalization of explicit ethical reasoning. Through comparative textual analysis of twelve chapters from six influential works—spanning from Adam Smith’s Wealth of Nations (1776) to Milton Friedman’s methodological essays (1953)— the research identifies a pattern in which ethics is less and less prevalent. Pre-formalist economists like Smith and Marx integrated moral arguments directly into their analytical frameworks, examining questions of exploitation, justice, and social welfare as central to economic inquiry. Post-formalist economists, pursuing …

The Effects Of Neighborhood And Interior Characteristics On Residential Sale Prices, Ella Sophie Hagman

Undergraduate Economics Working Paper Series

This study analyses to what extent certain neighborhood and interior characteristics affect residential sale prices, after accounting for standard property variables. This is important to examine in order to understand the function of the housing market, the sources of price differences, and whether residential values can be controlled by prioritizing specific desirable property features. The study is based on a dataset of approximately 330,000 observations from the Multiple Listing Service (MLS), as well as walkability data obtained from Walk Score. The data is analyzed in Stata, using three regression models with different combinations of explanatory variables. The results show that …

The Impact Of Property Tax Exemptions On The Hospital Real Estate Utilization, Howard Allen Levine

Doctoral Dissertations and Projects

This dissertation analyzes the effects of property tax exemptions on real estate utilization by hospitals in the production of medical services. Economic theory suggests that differential taxing creates inefficiencies causing destruction of wealth from deadweight loss. Property taxation is done by state and local governments. State and local governments spend 4.5 trillion dollars annually in the United States (Pustejovsky & Little, 2023, p. 2). Although only spending on services using real estate has efficiency effects due to real estate taxes, every 1% gain in overall efficiency is 45 billion dollars saved annually if the results can be generalized to all …

The Nexus Between Sino-African Economic Engagement, Us-African Security Cooperation And Foreign Direct Investment: National Security Implications Using A Comparative Analysis Of Nigeria And Other Selected African Countries, Chine Sp Logan

Doctoral Dissertations and Projects

This study examines the intricate interplay between the United States-African Security Partnership, China’s African Economic Partnership-Belt and Road Initiatives (BRI), and the influx of foreign direct investment (FDI) in Africa. It delves into the nuances of the US-African Security Partnership, focusing on US military training and security assistance through the United States African Command (AFRICOM) and the China-Africa BRI initiative, which centers on loan funding. Moreover, it analyzes how national security considerations influence FDI inflow. By scrutinizing the roles of robust institutions, the study evaluates how these factors impact the long-term achievement of the United Nations' sustainable development goals for …

A De-Dollarizing World: How Sanctions Catalyze De-Dollarizing Efforts In Russia And China, Karina S. Amaach

Senior Theses

For nearly a century, the United States has occupied the title as the world’s leading superpower nation. Such power has granted the US great economic responsibility, particularly highlighting the dollar’s dominant role as the international reserve and trade currency. However, the rise of competing powers– most notably China and Russia– have posed great threats to this continued economic dominance of the United States. This thesis examines how U.S. economic sanctions– often described as America’s greatest financial tool– have inadvertently motivated de-dollarization efforts led by these two nations. Drawing on interdisciplinary scholarship in foreign affairs, international political economy, and intergovernmental financial …

Essays On Development Economics, Environmental Economics, And Political Economy, Weihong Li

Economics Theses and Dissertations

Chapter 1 explores the strategic behavior of provincial leaders in China in response to visits by central government leaders. I find that such behavior is correlated with provincial leaders’ personal characteristics and their connections with the visitors. Meanwhile, acting strategically during these visits has a positive and significant effect on overall promotions, but a positive and insignificant effect on promotions to the most important positions in the Politburo.

Chapter 2 examines the impact of the Confucian norms on the spatial heterogeneity of fertility rates and sex-selective abortions in contemporary China. To overcome the challenge of quantifying cultural norms, I construct …

Shelter From The Storm: Public Library Value And Community Adaptive Capacities, Margo Gustina

Economics ETDs

This dissertation contributes to theoretical framing within the discipline of library science, while building out empirical methods for quantitatively valuing broadly loved public libraries. Chapter 1 lays the foundation for understanding how analysis public libraries must always be set within regional contexts. Chapter 2 demonstrates that positive voter valuation of public libraries is driven by proximity to a library building by using data from public funding referendum events. Chapter 3 estimates a reduction of 0.75 percentage point (p=0.002) in graduation rates where public libraries were closed (but school instruction was in-person) from COVID closures. Chapter 4 builds on the previous …

Perception, Payment, And Pollution- Examining The Effects Of Air Quality On Health And Healthcare, Colin Sleeper

Economics ETDs

Abstract

This dissertation examines how air quality and public attention to environmental shock affect perceived health status and healthcare utilization. The first chapter uses publicly available survey data from BRFSS and a triple difference framework to analyze the effects of the 2018 wildfire season in Oregon on self-reported mental and physical health. Findings indicate that those in Oregon in 2018, during the period of heightened attention to wildfire smoke, experienced approximately 1.4 additional poor mental health days, on average. The second chapter includes Merative MarketScan commercial insurance claims data to test whether these changes translate into a behavioral response. Results …

Agricultural Water Management, Farmer Decision-Making And Climate Adaptation In Dryland Agriculture: A Case Of The Middle Rio Grande Basin, Oluwatosin A. Olofinsao

Economics ETDs

Agriculture in dryland regions faces mounting pressure from climate change, water scarcity, and shifting land-use demands. The Middle Rio Grande Basin (MRGB) of central New Mexico exemplifies these challenges, where irrigated agriculture relies on increasingly variable surface water supplies. This dissertation examines agricultural water use, farmer decision-making, and adaptation strategies across farm types and climate conditions in the MRGB. The first study presents a spatial descriptive analysis of farm size, crop patterns, groundwater access, evapotranspiration (ET), and effective ET, revealing a landscape numerically dominated by smallholder farms that account for a substantial share of irrigation water use. The second study …

The Effects Of Food Insecurity And Child Health On Educational Achievement In Virginia Counties, Peyton T. Randall

Honors Projects

This study examines the relationship between county-level socioeconomic and demographic factors and student performance on Virginia Standards of Learning (SOL) math and reading assessments in 2023. Using data from 127 of Virginia’s 133 independent counties and cities, this study conducts an ordinary least squares (OLS) regression. The analysis shows a strong negative association between food insecurity, measured by the Identified Student Percentage eligible for free school lunch (ISP), and chronic absenteeism with SOL pass rates. These findings show food insecurity and absenteeism as key drivers for achievement disparities, suggesting a need for further interventions and broader research using school-level and …

More Than The Sum Of Its Sexes: Functional Constraints, Embodied Capital, And Age-Structured Labor In Human Forager Economies, Eric Schniter, Hillard Kaplan, Brenda Bowser, Cari Goetz

ESI Publications

"The paper's rough consensus attributes the SDoL to differential variance in food returns across male- and female-typical foraging domains, sourcing this primarily to Bird and Codding (2015) and Kelly's (2013) reframe of the classic 'hunting vs. gathering' axis as 'risky vs. non-risky foraging.' Indeed, the data show that males more often pursue large game and honey, resources that yield higher caloric returns but with high unpredictability, injury risk, and failure rates. Females, especially those with dependent young, more often target plant foods and small game that produce steadier, lower-variance returns. But variance-buffering is a proximate ecological account, not a life …

Early Detection Of Alzheimer's Disease And Related Dementias From Spontaneous Speech Using Foundation Speech And Language Models: Comparative Evaluation, Jingyu Li, Lingchao Mao, Xi Mao, Hairong Wang, Zhendong Wang, Xuelei Sherry Ni

School of Economics and Finance Faculty Publications

Background: Alzheimer's disease and related dementias (ADRD) are progressive neurodegenerative conditions where early detection is critical for timely intervention and care planning. However, current diagnostic methods are often inaccessible, costly, and delayed, especially for underserved populations. There is a growing need for scalable, noninvasive tools that can support timely diagnosis. Spontaneous speech contains rich acoustic and linguistic markers that can serve as noninvasive behavioral markers for cognitive decline. Foundation models, pretrained on large-scale audio or text data, generate high-dimensional embeddings that encode rich contextual and acoustic information.

Objective: This study benchmarks open-source foundation language and speech models to evaluate their …

The "Missing Self-Employed": How Better Data Change The Picture Of Self-Employment In The United States, Katharine G. Abraham, Susan N. Houseman, Beth C. Truesdale

Upjohn Institute Policy Papers

How economically secure are self-employed workers? Accurate answers to this question depend on data that capture the full range of self-employed people, including business owners, independent contractors, and those working on an informal, often cash basis. Using data from the 2025 American Job Quality Study, we demonstrate that, because of the way standard survey questions are worded, a substantial number of self-employed people are likely miscoded as employees in existing surveys. Correctly including these “missing self-employed” increases the share of workers who are self-employed on their main job by nearly 50 percent. Compared to the self-employed captured by standard survey …

Undertaking Short-Term Finance Transactions In Brazil - An Historic And Modern Look At The Brazilian Economy And Associated Risks, Shawn M. D'Aversa

Student Research

The following report discusses the risks and construction of a hypothetical short-term trade finance transaction involving the five parties: Citibank N.A., Caterpillar Inc. (CAT), Banco Do Brasil, Paracatu Gold Mine and EXIM Bank. Fair warning: this is a long paper for a short-term transaction.

For the deal, Caterpillar Inc. (CAT) has approached Citibank N.A. in New York regarding a financing transaction for five 797F-400 short-ton haul trucks. The trucks are worth $5mn each, including the costs of training and spare parts, for a total of $25mn. Put simply, the trucks are beasts for mining. They will then be shipped to …

Resilience In Place Names: German-Hehe War Memories And Cultural Identity In Iringa Toponyms, Claudio G. Kisake, Sophilini M. Yisega, Spemba E. Spemba

Journal of Humanities and Social Sciences

Toponyms, or place names, act as vital markers of historical memory, cultural identity and resilience. In Iringa, Tanzania, toponymy offers valuable insights into the enduring impacts associated with the German-Hehe War (1890–1898), and colonial encounters on indigenous communities. This study explores how place names—such as Kitanzini (‘a place with a noose for hanging people’), Ilundamatwe or Lundamatwe (‘a collection of slaughtered heads’), and Gangilonga (‘the speaking stone’)—convey narratives of Hehe war superiority, resistance, and survival. Using a qualitative approach, the research incorporates archival sources, oral histories, and linguistic analysis to investigate the stories behind naming and renaming, the role of …

Perception Of Asset Price Bubbles In Graphical Data, Cooper P. Vining

Honors Theses

This thesis studies how individuals judge asset price paths and bubbles from graphical data. It primarily investigates whether individuals can differentiate simulated asset price paths that are generated from pure random walks, and graphs that have a bubble element. This question is important because inventors and ordinary people often interpret price paths visually.

To test this, the project creates simulated asset price paths using random walks and bubble multipliers. The survey has four types of graphs: pure random walks, random walks with a 25% bubble, random walks with a 50% bubble, and random walks with a 75% bubble. The graphs …

Assessing College Tuition And Wage Prospects For Careers In Archaeology, Angelina H. Gutierrez

Honors Capstones

The pressures of rising college tuition are raising questions about whether a degree in higher education is worth the return on investment in today's society and economy. This study aims to acknowledge the issues of affording college and the opportunities granted in the face of college wealth premiums from the perspective of the field of archaeology. The college wealth premium is understood as additionalopportunities and increased salaries offered to those with a degree in higher education compared to those without. Using the Midwestern United States as a case study, I discuss the gender/race wage gap, college debt, loan inequity, and …

The Effects Of Government Policies On The Stock Market, Samruddhi Somani, Dr. Holger Kern

Caravel Undergraduate Research Journal

What is the most effective government policy to boost stock returns and, subsequently, to foster economic growth, especially during an economic crisis? This paper examines the effects of various government actions on stock market performance during the global financial crisis of 2007. As expected from rational investors, nearly all of the variation in index levels is explained by the variation in index futures levels, which reflect market expectations. Index and future levels were collected for June 2007-December 2009 using Bloomberg, which tracks data for various financial instruments. The financial crisis timeline furnished by the New York Federal Reserve Board on …

Payrolling In The Deep, Kyle Rosenfeld

Business and Economics Honors Papers

This study examines how Major League Baseball teams can build their rosters to spend their payroll more efficiently. Using a manually constructed dataset, consisting of thirty teams over the past five years, this paper studies different payroll allocation strategies, such as the percentage of a team’s payroll to homegrown players or free agents, to improve the efficiency of how an MLB club is spending. Through running regression models, results have shown there is a statistically significant positive relationship between how efficient MLB teams spend their payrolls to the percentage of a team’s payroll designated to homegrown players. Additionally, there is …
