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 …

The Lion's Share: The Secret Land Grab Of Drake's Circumnavigation, Melissa Cole Darby

Anthropology Faculty Publications and Presentations

Francis Drake’s journey around the world between 1577 and 1580 is renowned as one of the most famous voyages in history. The circumnavigation was a great achievement for England, but the official story Queen Elizabeth and her Privy Council maintained for nine years was that Drake was a pirate, and that the treasure he captured on the voyage would be returned to Spain. Upon his return, information about the voyage and his route were suppressed and the crew was sworn to secrecy: they were not to reveal where they travelled on ‘pain of death’. Here I present the case that …

Five Corridors: A Community Health Needs Assessment Of Horry County, Stephen Borders, Hayley Bilko, Molly Craig, Olivia Guthrie, Ashley Mcconnell, Emily Mcgowan, Anna Quick, Abigail Rike, Makayla Wilson

Public Health

This report presents a Community Health Needs Assessment (CHNA) of Horry County, South Carolina. Its central analytical contribution is a five-corridor framework derived from k-means cluster analysis of the county's 76 residential census tracts, drawing on social and economic indicators from the American Community Survey and health estimates from the CDC PLACES program. The analysis organizes the county into five distinct community types — Affluent Coastal Retirement, Moderate Coastal Retirement, Inland Rural/Suburban Transitional, Concentrated Disadvantage, and Hispanic Hospitality Worker — each with a characteristic profile of social and health conditions.

Within this framework, the assessment examines a range of social …

What Complexity Costs: Growth, Productive Capability, And The Vulnerability Of Interconnectedness, Pete Mcniff

Master's Theses

Growth depends on the sophistication of what an economy can produce, but economies that have specialized more deeply depend on the market access that sustains it. I test whether this dependence makes complex economies more vulnerable when access is disrupted, computing the Economic Complexity Index (ECI) from firm-level records in the U.S. Census of Manufactures (1850--1880) and using the Panic of 1873 as a natural experiment to measure county-level market access shocks from railroad bond defaults following Dutta (2024) and Donaldson and Hornbeck (2016). ECI predicts production and employment growth across all three decade windows, with the association strengthening as …

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.

Trust, Civic Institutions, And Crisis: A Study Of Civic Culture In Italy, Nolan Joseph Sherwood

Master's Theses

This paper examines whether cultural familism — the orientation of trust toward family at the expense of strangers and civic institutions — shapes civic institutional engagement in Italy across three levels of analysis. The first analysis links four familism indices constructed from the European Values Study (2017) to pre-COVID municipal 5 per mille tax allocation rates across approximately 7,700 Italian municipalities, finding that higher Trust Gap and Institutional Distrust robustly predict lower baseline civic giving, both nationally and within each region. The second analysis uses a Regression Discontinuity in Time design exploiting the sharp onset of COVID-19 in 2020, finding …

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 …

Perceptions Of Care: An Exploratory Case Study On Residents’ Perceptions Of Neighborhood And City Maintenance, Taylor Coats

Transforming Communities

Where one lives impacts both their physical and mental well-being. Though one’s builtenvironment is an important factor, the perception of one’s environment influences mental well-being. This qualitative study examines what influences residents’ perceptions of theirneighborhood and local governmental efforts to maintain and improve their community. Thisstudy utilized a case study methodology to interview residents, stakeholders, and politicians intwo neighborhoods in a mid-sized urban city in the Midwest (N = 16). This study identified threecore aspects that influence participants' perceptions of their neighborhoods and city efforts tomaintain and improve their community: 1) history with the city; 2) geographic location withinsegregated neighborhoods; …

Tùn-Scene And A-Futurism: Biomythography, Opacity, And Posthuman Imagination, Minglu Du

Masters Theses

Grounded in the author’s position as a Chinese feminist, this thesis examines how East Asian women, as well as East Asian-coded femininity more broadly, are objectified and othered within futurist visual culture in the age of artificial intelligence. Through an engagement with ornamentalism, techno-Orientalism, and posthumanism1 , it argues that the persistent figure of the feminized humanoid cyborg continues to reproduce colonial and patriarchal structures of desire, rendering marginalized bodies as fetishized and violable surfaces. In response, the thesis develops Tùn-Scene, a biomythographic artistic framework and the first experiment in what the author provisionally names A-Futurism. Drawing on Donna Haraway’s …

Soft Power, Arab Media And Sports Mega Events: Coverage Of Fifa 2022 And Lessons For Future Arab Hosting, Lynne Kennedy, Maaira Shahbaz, Ala Al Rajabi

All Works

Sport mega-events (SMEs) increasingly transcend athletic competition, functioning as strategic instruments for national identity formation, statecraft, and soft power projection. This dynamic is particularly pronounced in the Gulf, where Qatar’s successful hosting reignited regional rivalries and attracted unprecedented global scrutiny. While existing scholars have extensively examined Western media portrayals of SMEs, a notable gap remains for academic engagement with Gulf media. Dismissed as state-controlled and analytically lacking, we contend that such media offer a rich site for exploring how small states use media as soft power, to construct and contest legitimacy, identity, and global influence. This analysis suggests how state-aligned …

Productive Armature, Gabriel Ofem Peter

Masters Theses

What if water was all you had, what if your only source of survival was a body of water? I shudder to think that some people get to be put in this situation in the world we live in. As I understand the importance of water to survival, it is obvious that water can be the only lifeline of survival for a community. This is the experience for residents of Makoko, Lagos. Their survival depends on the Lagos Lagoon, a large body of water flowing in from the Atlantic Ocean. This research looks beyond the surface of what this community …

Material Costs, Karima Weinman

Masters Theses

This thesis investigates how migration fatality and disappearance data can be reinterpreted through material craft to create a more reflective encounter with information. Working with the Missing Migrants Project's dataset, this project asks how design can communicate dimensions of human loss that conventional data visualization cannot reach.

The work situates contemporary border violence within a longer colonial history, arguing that the logics of surveillance and quantification that structured European imperial expansion persist in the databases that govern mobility in the Mediterranean today.

Adapting And Promoting Tourism For Children In Venice And The Lagoon Islands: A Comparative Analysis Of Food-Related Discourse Strategies In English And In Italian, Daniela Cesiri Prof.

International Journal of Islands Research

According to the latest available version of the Annual Tourism Survey drafted by the City of Venice, in 2023, 12,628,079 tourists visited Venice and the Lagoon Islands (Bettiol & Marini, 2025). This survey does not provide data on the age groups of these visitors, but they are available in the previous version of the same Survey (Bianchetto & Marini, 2022), which reports that 29% of tourists were in the 46-71 age group. Therefore, we can presume that, excluding the older age groups, quite a large proportion of visitors is likely composed of young tourists and families with children. This study …

Labor Market Responses To Ai: Measuring Wage Effects Across U.S. Occupations, Kaitlin Pham, Karla Rodriguez

Undergraduate Economics Working Paper Series

Artificial intelligence (AI) is rapidly changing economies around the world, with some experts predicting an impact greater than the Industrial Revolution. As AI becomes more common in daily life and business, questions have grown about how it might affect jobs, wages, and inequality. The rise of automation and highly capable AI models has made people wonder which occupations will benefit and which might be at risk. This study looks at how exposure to AI technologies affects wage trajectories in the United States. Using occupational-level data from O*NET and the U.S. Bureau of Labor Statistics, we build an AI exposure index …

Flowing Borders: U.S. Border Externalization In Latin America And The Los Angeles Declaration On Migration And Protection, Magdalena Olvera Hernandez

Master's Theses

In recent years, Latin America has emerged as a central transit region for extracontinental migrants originating from Africa, Asia, and the Middle East who seek to reach North America through alternative routes. This thesis examines the Los Angeles Declaration on Migration and Protection, among other regional migration governance frameworks that have reshaped migratory flows, state responsibilities, and protection outcomes in the Western Hemisphere. Focusing on the Darién Gap as a strategic chokepoint, the study analyzes the effects of coordinated migration policies, border externalization, and differentiated state roles on extracontinental mobility.

Drawing on official migration statistics from Panama, the United States, …

Shoplifting: Analyzing Spatial And Temporal Patterns, Elizabeth Petrenko

Dissertations and Theses

Shoplifting has contributed to significant losses in Oregon, reaching nearly $956 million in 2022. While overall property crime in Portland, Oregon, dropped between 2023 and 2024, reported shoplifting incidents increased by 50.0%. In Oregon, stealing property worth $100 or less is third-degree theft and a Class C misdemeanor. Second-degree theft involving stealing property between $100 and $1,000 is a Class A misdemeanor. Although often classified as petty or minor theft, shoplifting imposes strain on retailers, consumers, and communities, which raises questions about the spatial and temporal distribution of this crime. This study uses Portland Police Bureau (PPB) offense data to …

Justice By Geography: District-Level Variation In Pretrial Release Outcomes Across Oregon, Ethan Loomis

Dissertations and Theses

AbstractOregon’s pretrial system operates under a common statewide legal framework, yet detention and release outcomes do not appear fully consistent across jurisdictions. Earlier research on pretrial decision-making has largely focused on judicial discretion, individual-level legal factors, and the use of risk assessment tools, while giving less attention to the district-level environments in which those decisions are made. This study examines whether variation in institutional capacity, political context, demographic composition, and socioeconomic conditions corresponds with differences in pretrial outcomes across Oregon’s circuit court districts.

The study draws from focal concerns theory, racial threat perspectives, and organizational approaches to court decision-making. Rather …

Beyond "Bad Apples": Political Identity, Moral Interpretation, And Institutional Response To Abuse, Laura Werner

Student Theses

This thesis examines how psychological explanatory frameworks and structural institutional response interact to shape how domestic violence and sexual abuse are understood and addressed. Drawing on behavioral design theory and John Dewey's transactional approach to experience, I argue that harm is interpreted through mental models that simultaneously shape both individual perception and institutional action. Using survey data from 736 participants, I demonstrate that endorsement of the "bad apples" explanatory framework, attributing abuse primarily to a small group of deviant individuals, is predicted by psychological essentialism, belief in a just world, social dominance orientation, and political conservatism. These findings suggest that …

The Effect Of Return-To-Office Mandates On Worker Engagement And Perceived Work-Family Conflict, Caleb M. Daughhetee

Doctoral Dissertations and Projects

The purpose of this cross-sectional, quasi-experimental study was to examine relationships among employee perceptions of return-to-office (RTO) mandates, employee engagement (EE), and work-family conflict (WFC) among previously remote U.S.-based workers. Despite extensive RTO mandates following the COVID-19 pandemic, limited research has examined the relationship between worker perceptions, EE, and work-family dynamics. Grounded in personal engagement theory (Kahn, 1990), role theory, and the Job Demands-Resources model, this study investigates whether RTO perceptions predict EE and WFC, and whether WFC mediates or moderates the relationship between RTO perceptions and EE. Data were collected from 145 participants using a researcher-developed RTO perception scale …

The S.A.V.E. Model Of Biblically-Based Existential Therapy For Residents Of The Assisted Living Facility Casa Di Riposo Sardara In Sardinia, Italy, Gregory K. Cherven

Doctoral Dissertations and Projects

Christian gerontological counseling, a traditionally non-progressive field, is a crucial area of ministry, particularly for older adults in assisted living facilities and nursing homes. At Casa di Riposo Sardara in Sardinia, Italy, many residents aged 70 and older lacked a solid biblical understanding of existence and eternal life, contributing to widespread existential anxiety among this population. To address this issue, the researcher developed the S.A.V.E. (solitude, autonomy, value, eternity) model of biblically based existential therapy. This model targets the four main pillars of existential therapy: meaninglessness, isolation, freedom, and death, offering biblical solutions for each. The approach incorporates positive imagery …

From Rituals To Resilience: Individuals’ Lived Experience Of Self-Reflective Relationship Therapy (Srrt), Ehsan Adib Shabahang

Doctoral Dissertations and Projects

This qualitative Husserlian descriptive phenomenological study addressed a gap in first-person accounts of brief self-guided preventive relationship interventions. One such intervention, Self-Reflective Relationship Therapy (SRRT), is a 6-week self-guided workbook combining structured reflection with brief connection practices. The purpose of the study was to describe individuals' first-person lived experiences 6 to 18 months after completing SRRT. Six participants completed asynchronous written reflections, and the data were analyzed using Husserlian descriptive phenomenology with Colaizzi's seven-step method. Participants described SRRT as a workable path toward reconnection after periods of emotional distance or strain. Carryover centered less on continued adherence to the workbook …

Building Cultural Wealth: A Look Into The 40x40 Council’S Rise East Plan, Camille L. Batiste

Master's Theses

This research began as an effort to understand how community-based organizations in neighborhoods that have experienced generational economic disinvestment address the financial and cultural wealth gap in their communities. With the 40x40 Council and its work in East Oakland serving as the case study, it is evident how this organization mobilizes to reverse the impact of cultural erasure and wealth exclusion, helping Black residents not just live, but thrive. With an enriched understanding of how the 40x40 Council frames its approach, implements its vision, and develops its longevity, the Rise East Plan utilizes an alternative wealth-building strategy that centers community, …
