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.

Linking Fishery Productivity To Child Health In The Coastal Tropics, Francisco Flores-Mejia

Master's Theses

Fish are a primary source of calories, macronutrients, and income for coastal communities around the world, but overfishing and environmental changes have dramatically reduced productivity in the majority of small-scale fisheries. The social costs of these losses are believed to be large, particularly in poorer communities, but most estimates of fishery productivity effects on households are contextual and difficult to generalize. We combine a remote sensing measure of pelagic fishery productivity with geolocated child health and growth data from 34 countries in the coastal tropics. We estimate that the difference between sustainedly good versus bad fishing conditions corresponds up to …

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 …

The Feather Of The Quill: How Folklore Shapes Human Relationships With Wildlife, Taylor Breeanne Nelson

Master's Theses

This thesis examines how folklore and cultural phenomena shape human relationships with wildlife, arguing that the stories a society tells about animals are not merely reflective of its values but are constitutive of them. Drawing on narrative research methods sourced from literature and academic journals and interviews with academics, conservationists, and community members, this project examines the role of animal folklore.

I discuss how narratives around wildlife evolved alongside the development of the United States, arguing that the beginnings of mainstream American conservation not only displaced existing communities but also erased the sophisticated human-animal relationships their traditions had long sustained. …

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.

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; …

Recruitment As Care: Building Trust With Hard-To-Reach Populations In Sensitive Health Research, Alexander N. Vera

MUSC Conference Presentations

Recruiting participants for sensitive health research on social media presents unique ethical and methodological challenges. This session shares lessons learned from a qualitative study examining how young adults in South Carolina use TikTok to seek sexual health information. The presentation highlights creative and trauma-informed recruitment strategies that successfully engaged a hard-to-reach population while maintaining participant trust and privacy. Attendees will learn how recruitment language, social media algorithms, and transparency practices shape engagement, and why building trust matters more than technology alone. The session also considers how these lessons can inform future research in health sciences librarianship, especially for librarians supporting …

Kev's Dinghy Boat Workshops, Ruiyang Xiao

Masters Theses

In a culture where convenience replaces process, this project argues that making — even when inefficient, imperfect, or unnecessary — enables forms of engagement that buying cannot.

Technologies and Services nowadays are able to fulfill human’s desire to travel and explore at ease. However, this convenience proposes a mode of engagement based only in deeper knowledge of context and thus our experience with the world around us is hence diminished. Our engagement with the world becomes heavily mediated, regulated and controlled.

This project investigates how hands-on engagement with water can reintroduce + restore our sense of joy, curiosity, consequence, and …

Kicau Kericau: The Chirps And Warbles Of A Bird-Human Story, Airien Ludin

Masters Theses

This thesis tells the tale of bird-human relationships and what it means to live alongside one another, subverting the hierarchical view of humans as above birds inherited from colonial history. It asks how the practice of illustration can function as a site of Two-Eyed Seeing, where scientific and local knowledge are held together as an entangled narrative. It also examines how mendongeng (storytelling), as I have experienced it within Indonesian culture and everyday contexts, can help us understand birds as a companion species with their own agency.

This project takes two forms: first, a picture book titled Sun Bird …

I Miss My Computer: Online Artistry, Web Aesthetics, And Coming-Of-Age In A Digital Landscape, Catherine Capeci

Masters Theses

This thesis explores how young artists develop their creative practices in a world informed by digitality. Through survey research of 44 art students between the ages of 14 and 22, as well as a process of autoethnographic inquiry, I examine how artists in high school and college relate to digital imagery, web archives, online gaming, and social media platforms, and how these experiences inform artmaking. I believe that art educators should explore how the internet informs aesthetic and conceptual sensibilities, and how these sensibilities show up in young artists’ work, more so than focus on digital media as its own …

Decision-Making In Early-Stage Startups: How Venture Capitalists And Angel Investors Evaluate Uncertainty, Andrew M. Pence

Dissertations

The purpose of this dissertation is to examine how venture capitalists (VCs) and angel investors (AIs) make investment decisions regarding early-stage startups. Using an Interpretative Phenomenological Analysis (IPA) framework—consisting of three core components: phenomenology, hermeneutics, and idiography—this study draws upon three decision-making models: the Rational Actor Model (RAM), the Heuristics and Biases model (H&B), and the Naturalistic Decision-Making model (NDM) to explore what motivates VCs and AIs to choose, for instance, “Company A over Company B.” Semi-structured interviews were conducted with 10 experienced venture investors to examine how they evaluate risk, assess founders and teams, and navigate the persistent uncertainty …

Playing Into Confidence: A Literature Review, Zoë J. Crowe

Expressive Therapies Theses

This integrative literature review examines the relationship between drama therapy and self-efficacy, and its implications for academic success. Traditional measures of achievement emphasize outcomes while overlooking the psychological processes that influence student engagement and persistence. Drawing on interdisciplinary literature, this review synthesizes research on how drama therapy supports self-efficacy through embodiment, role exploration, and structured play. These processes create safe, participatory environments where individuals can rehearse new behaviors and reconstruct self-perceptions. They also align with key mechanisms of self-efficacy development, including mastery experiences and emotional regulation. This review identifies gaps in current research, particularly the limited integration of drama therapy …

Examining Whether The Relationships Between Specific Psychiatric Diagnoses And Both Adolescent Suicide And Reoffending Are Moderated By Sex, Michael T. Baglivio, Katherine Jackowski, Brooke Neupaver, Grayson Black, Bailee Perry, Kevin T. Wolff

Publications and Research

The current study examines the relationships between specific psychiatric diagnoses and both adolescent suicide and reoffending, the implications of adverse childhood experiences on these outcomes, and assesses whether these relationships are moderated by sex. Using a multilayer multiyear statewide sample of 6,515 adolescents who completed juvenile justice residential placements, logistic regression and moderation models were used to examine these relationships. Findings demonstrate that the rate of suicidal ideation was 2.5 times higher for female youth, while the recidivism rate was 1.7 times higher for males. Psychiatric diagnoses prevalence ranged from 65.9% for conduct disorder to less than 1% for personality …

The Ever-Changing Immigration Experience: An Oral History On The Impacts Of Immigration For Connecticut Latine Residents / Una Experiencia En Cambio Constante: Una Historia Oral De Los Impactos De La Inmigración Por Habitantes Latines En Connecticut, Sam S. Arevalo-Hoefer

Honors Scholar Theses

This paper is an oral history study focused on Latine immigration experiences in Connecticut from six different individuals sharing their stories and perspectives on the immigration process. I focus on the act of testimony as a source of grassroots knowledge and attempt to spread this notion of community wisdom further through the creation of zines (small-batch, self-published, non-commercial shortform magazines) as a means of making information more accessible and reaching a larger audience on a local level.

I use oral histories as a method of research that can achieve a deeper, more human understanding of how macro level political decisions …

Finding A Way Out Of The Filter Bubble: The Confusion Of A Heavy Social Media User, Longwen Miao

Masters Theses

This thesis studies how algorithmic recommendation systems reshape visual perception, aesthetic judgment, and the construction of selfhood within contemporary digital culture.

Everything begins with the experience of repeatedly encountering algorithmically recommended content on everyday digital platforms. On these platforms, images, sounds, and social interactions are continuously selected, repeated, and reorganized by predictive systems, forming an environment in which perception is constantly structured and adjusted.

From this observation, the research raises two central questions: how do algorithmic recommendation systems reshape visual perception, aesthetic judgment, and self-recognition, and how might these systems be intervened in or made perceptible through artistic practice? Within …

I Believe, Rusudan Dushuashvili

Masters Theses

This thesis investigates how products become believable and desirable through the stories that surround them, and how design enables the continuous cycle of desire that defines consumption. Drawing on  the underlying structures of myth-making, identity, and belonging that allow consumer culture to function, it argues that consumer culture operates through the same instruments older systems of belief have always used — narrative, ritual, sacred objects, and shared language — and that design is what makes the story stick to the object.

“I Believe” is an archive of objects collected from contemporary consumer culture. Half are products found in the marketplace; …

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 …

¡Estamos Aqui!: The Underrepresentation Of Latinos In Professional Sports And Sports Media, Antonio Hernandez

University Honors Theses

The Latino population has had a long and complicated history within the United States. Since the turn of the 21st century, Latinos continue to become the largest minority group within the country. As the Latino population continues to rise, other industries have failed to properly represent the community. Within the world of professional sports, Latinos continue to be grossly underrepresented, with professional athletes from Latino backgrounds representing less than 6% of all professional athletes across all disciplines. This number is just under ¼ of the total percentage of Latinos within the United States. With Latino's influence of other cultural phenomena …

The Educational Gender Gap Explored Through The Lens Of Hegemonic Masculinity, Marcell V. Csikos

University Honors Theses

Women's college attendance skyrocketed with the passing of Title IX, and by the eighties, college campuses featured men and women at an even fifty-fifty split. Today, women make up over fifty-seven percent of college students. It is not a new phenomenon, studies and surveys have shown that women are doing better at school for decades, but they rarely tie men's underperformance to the concept of masculinity. The study of hegemonic masculinity is an overarching theory that looks at the values, rules, and dynamics that men have to follow in order to keep their social status. This literature review uses said …

Reclamando Corazón Y Voz: Latinas Speak Their Truth Through Plática As Resistance In California Community College Learning Disabilities Assessments, Maricela Becerra

Dissertations

Although California Community Colleges (CCCs) offer learning disability (LD) assessments to determine eligibility for academic accommodations, for Latina students navigating converging forces of race, gender, language, citizenship, and ableism, these assessments often surface unspoken histories of harm. This study advanced Chicana feminista DisCrit (CFDC), extending disability critical race theory through Chicana spirituality and cultural intuition to examine possibilities when an educadora situates assessments in a plática grounded in consideración—respectful, relational, and unhurried care.

Rooted in Chicana feminist pláticas methodology and authored from the positionality of a disabled Latina scholar–practitioner, this qualitative decolonial dissertation explored how Latina students reflected on …

Rainbow Promises, Uneven Promises: Framing Lgbtqia+ Educational Policy And Possibility In Education, Gerardo Lorenzo-Saucedo

Dissertations

Despite the expansion of LGBTQIA+ inclusive policies in K-12 education, disparities in students’ experiences with safety and belonging persist. This qualitative case study examines how such policies are interpreted and enacted within a high school and district in Southern California, and how these processes shape LGBTQIA+ students’ experiences.

Guided by ecological systems theory, queer theory, and multiple streams theory, this study conceptualizes policy implementation as a dynamic and socially constructed process influenced by power, ideology, and institutional context. Data were collected through interviews, document and artifact analysis, and observations, with analysis that used a multi-phased coding procedure.

Findings revealed that …

Care Ecologies Between Knots, Eliza R. Marris

Masters Theses

Discarded fibers like raw wool behave the way harm reduction does. Harm reduction resists stigma and works to move beyond assumptions and oversimplifications of substance use and addiction. Wool is irregular, complicated, and emotionally charged. It resists compression and maintains its own being even when pulled apart. Working with raw wool is in relationship with complexity, as is harm reduction.

At its core, harm reduction is grounded in thoughtfulness and empathy towards people, their lived experience, and its nuances. It is a witness to lives, memories, and imprints, acknowledging the entangled realities of addiction. Our detachment from fiber remainders, materials …

The Marathon Without Running: Experiencing A Runner's Sensorial Journey, Harin Kim

Masters Theses

The marathon is defined not by motion alone, but by the changing conditions a body moves through—and remains within—over time. Breath, cadence, heat, sound, crowd compression and attention fluctuate, producing phases that structure the race from within. These interior states are difficult to access by spectators from the sidelines, yet they are precisely what shape the runner’s experience.

This thesis begins with a simple but unconventional question: How can an exhibition translate the runner’s physical sensations and emotions into a multidimensional experience for spectators who do not run? Through a sequence of pop-up exhibitions placed along the New York City …

Draw To Breathe, Ranran Ma

Masters Theses

This thesis explores visual expression in drawing as an intuitive mode of thinking suited to everyday life—a form of expression that runs parallel to language and surpasses it.

The project begins with a daily Post-it note drawing practice. These drawings often emerge before conscious understanding, subsequently accompanied by brief text, allowing image and word to resonate through emotion and intuition. Through the use of small-scale, portable, low-pressure materials, and with immediacy and intuitive freedom as the foundation of making, a visual language system grounded in the self develops. Through this sustained practice, I developed an instruction-based card system titled Draw …

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 …

Weaving Grounds: Connecting Canyons And Empowering Borderland Communities, Maria D. Lopez Vazquez

Masters Theses

National policies materialize in the United States-Mexico political divide, also known as the borderlands. Willow Canyon is a dissected land form inextricably linked to the Tijuana River watershed, forming with the adjacent landforms on both sides of the border one landscape. The Guadalupe Hidalgo Treaty¹, signed in 1848 by the US and Mexican governments, traced an arbitrary line across these landscapes, disregarding their relationship. The consequences of these actions are visible in the physical deterioration of the landscape and ecology, as the hydrological cycle has been modified. In the 1940’s, the picturesque flow of Willow Canyon was dissected by urbanization, …

Carve, Release, Expand: A Spatial Exploration Of The Clandestine Music Spaces Of Chicago, Katie Lesh

Masters Theses

The architectural disciplines, and particularly that of landscape architecture and urban design, have shifted into focusing on “revival” of public and urban spaces but what does this truly mean? On the surface it can look like taking warehouse districts in a city and creating a master plan to turn them into artist villages or taking space underneath a highway to turn into a linear park. But what is lost in the process of doing so? The question is much bigger than myself but in the case of Chicago, the city has been home to vibrant music and art communities that …

The Body Has Its Own Time, Wen Zhang

Masters Theses

In embodied practice, the artist’s experience and body become the medium through which thought and expression take form, not as illustration, but as primary material. Performance art has long occupied an unstable position within contemporary art: celebrated in retrospect, underfunded in practice, and selectively institutionalized. Its marginality has never been evenly distributed. Certain bodies, female, racialized, aging, non-normative, have remained further outside the archive than others, their work harder to collect, harder to value, and easier to forget. To work in performance, particularly as a woman, is to work within that contradiction.

For me, performance is less a form than …

Menstrual Muses: Art, Storytelling, And The Care-Based Communication Of Menstrual Justice, Burcu Koleli

Masters Theses

Menstrual Muses is an artistic research project comprising a written thesis and a body of work developed across soft sculpture, ceramics, illustration, graphic memoir, digital media, and participatory workshops. The written component operates alongside the studio practice, outlining the project’s theoretical framework, methodology, and context while engaging questions of communication, accessibility, embodiment, and stigma. It situates menstruation within feminist discourse, examining how it has been culturally silenced, regulated, and shaped through systems of power.

The artistic work functions as research materialized through practice, responding to the central question of how my art can facilitate conversations around menstrual justice. It explores …
