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.

Solid Waste Management In Greater Khartoum City, Sudan, Roba Mahmoud

Student Theses 2015-Present

This study investigates the rising solid waste management (SWM) dilemma in Greater Khartoum City (GKC), a critical environmental and public health issue caused by fast urbanization and inadequate infrastructure, with historical linkages to Sudan's colonial and postcolonial growth. Chapter 1 describes the current problem using quantitative and qualitative data, demonstrating that GKC produces approximately 3,340 tons of waste each day, with 56% organic matter, 8% plastics, and 16% paper. Collection efficiency remains severely poor, at 31.5%. Informal recyclers known as Nakasha or Barkata collect approximately 7% of total waste, supporting roughly 3,900 people, whereas filthy open dumps and unsorted medical …

CMC Senior Theses

In order to stay competitive in an expansionary industry like healthcare, companies must consistently meet market demands for growth. This paper builds an empirical model to identify which growth strategies are most highly rewarded by the public markets. The model consists of a data set of 70 healthcare companies, across various healthcare verticals, to measure market returns from 2010 to 2023. The number of completed acquisitions is used as a proxy to identify each company’s propensity towards a growth strategy. Factors from the Fama-French Model and dummy variables used to signal growth strategy expertise, indicate that firms who invest more …

Providing End-Of-Life Counseling: A Narrative Inquiry, Carol Hecht, Sibyl West

Adultspan Journal

This qualitative study aimed to address the gap in the research related to end-of-life counseling by exploring the experiences of counselors working with clients at end of life. While counseling literature and education are lacking regarding end of life, many counselors will work alongside clients approaching death. The purpose of this study was twofold: (a) to better understand the nuanced experiences of counselors providing end-of-life counseling and (b) to explore the supports and preparations helpful for counselors to provide end-of-life counseling. A narrative approach, using the Listening Guide (Gilligan, 2015), was employed to analyze and present the stories of three …

Considerations Of Medicare Telehealth Services With Older Adults, Sonah Kho, Amanda Dediego

Adultspan Journal

The onset of the COVID-19 pandemic set in motion a rapid expansion of mental health services offered via telehealth. With this rapid expansion came the need to examine how policy and practice should be shaped in a future where telehealth is considered common in counseling practice. For counselors to understand how to support older adult clients in using telehealth services, they must understand telehealth policy. Following the eligibility of licensed counselors to participate in Medicare, counselors need to stay abreast of regulatory changes regarding restrictions and regulations on use of telehealth for mental and behavioral health services, including video and …

Does Higher Socioeconomic Status Associate With Better Mental Health Outcomes Among Primary Caregivers In Rural China?, Wenwen Zhang

Master's Theses

This study explores the intricate relationship between socioeconomic status (SES) and the mental health outcomes of primary caregivers in rural China, focusing on the Early Childhood Development (ECD) context in Ya'an. Anchored in a major intervention project launched in 2023, the study critically examines the hypothesis that higher socioeconomic status correlates with lower levels of negative emotions among caregivers.

Utilizing cross-sectional data, the research investigates how educational attainment and household income influence caregivers' mental health, measured through the DASS-21 score in three dimensions: stress, anxiety, and depression. The findings reveal that higher household income and educational levels are significantly associated …

Emotion Regulation Strategies And Perceived Emotional Intelligence: The Effect Of Age., Iwanna Sepiadou

The aim of this study was to investigate the relationship between perceived emotional intelligence and the reported use of cognitive reappraisal and expressive suppression. We also investigated the possible effects of age on the aforementioned variables. The total sample consisted of 379 people (158 men, 220 women, 1 unreported). Across participants, 273 were young (20-39 years old) and 106 were middle-aged (40-65 years old). We found statistically significant positive correlations between the dimensions of perceived emotional intelligence and the reported use of cognitive reappraisal and negative primarily correlations between the dimensions of perceived emotional intelligence and the reported use of …

Cognitive And Economic Development, John Luke Gallup

OHSU-PSU School of Public Health Annual Conference

A burgeoning literature finds that early childhood risk factors have large causal effects on individuals' cognitive development, education and earnings, but has not assessed the impact on the economy as a whole.

Cognitive ability is the foundation of human capital and the capacity to learn. The risk factors for poor cognitive development are very high in many countries. Each risk factor also causes child mortality, making child survival a viable proxy for good cognitive development conditions. The cognitive development of current workers happened decades earlier when they were children, providing a predetermined correlate. Controlling for country characteristics, income levels and …

The Unequal Distribution Of Social Risk For Black Men Across The Life-Span. A Novel Framework., Waleed Y. Sami

Adultspan Journal

This conceptual overview offers a comprehensive overview of systemic pathways that negatively impact the mental health of Black Men throughout their lives. Our argument highlights the importance for counselors and mental health professionals to utilize a thorough social risk assessment that considers these pathways in order to effectively address the mental health needs of Black Men while fostering positive working relationships. This overview strongly advocates for the use of context and structural determinants when evaluating mental health symptoms. Without an appropriate understanding of social risk and determinants, counselors may inadvertently perpetuate disparities by decontextualizing symptomology, and reproducing racist discourse.

Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia

Journal of Nonprofit Innovation

Urban farming can enhance the lives of communities and help reduce food scarcity. This paper presents a conceptual prototype of an efficient urban farming community that can be scaled for a single apartment building or an entire community across all global geoeconomics regions, including densely populated cities and rural, developing towns and communities. When deployed in coordination with smart crop choices, local farm support, and efficient transportation then the result isn’t just sustainability, but also increasing fresh produce accessibility, optimizing nutritional value, eliminating the use of ‘forever chemicals’, reducing transportation costs, and fostering global environmental benefits.

Analysing Pandemic Induced Economic Inequality In Developing Nations, Ravneet Kaur Bhogal

International Journal on Responsibility

The dawn of the new decade of the 21st century saw an unprecedented global crisis. This crisis led the world to halt economic and social progress. It led to a galloping increase in the economic inequality and migration of people in search of opportunities to save them from the current situation. The developing nations saw a sea of people migrating back to their roots in search of safe havens. This has led to the loss of jobs which has increased income inequality. Migrants face the risk of contagion and also the possible loss of employment, wages, and health insurance coverage. …

The Child Nutrition Cost Of Weather Shocks In Nigeria, Danielle M. Abaya

Master's Theses

Child malnutrition is alarmingly high in Nigeria with the highest number of malnourished children, the second highest population of stunted children worldwide and 17 million Nigerians facing food insecurity. According to the World Health Organization, children are predicted to suffer about 80% of weather-related illnesses and deaths. As climate change continues to pose the greatest health threat and while scientists predict its irreversible effects in the next 10 years, countries such as Nigeria are already experiencing the burden of climate change today. This study uses total rainfall to measure precipitation and two Enhanced Vegetation Index variables, total change in greenness …

The Influences Of The Public Health Care System And Education System On The Economic Growth Of Swaziland, Grace Greer

International and Global Studies Undergraduate Honors Theses

The Kingdom of Eswatini, also known as Swaziland, has one of the youngest populations in the world with over 70% of citizens being under the age of 18 years old. This creates a substantial opportunity for economic, social, and educational growth in a country previously plagued with diseases such as HIV/AIDS, poor health care infrastructure cutting off thousands from basic care, and an educational system with a very low attendance rate and an even lower graduation rate. By evaluating the root causes of such issues dating back to the colonial era there is an opportunity to reprioritize health care and …

Debt And The Medicare Eligibility Discontinuity: Disparate Effects Across Households, Olivia Falck

Honors Theses

Public health insurance programs like Medicare and Medicaid have been shown to help reduce household debt caused by healthcare costs. The impact of health insurance literacy makes the relationship between public health programs and debt more ambiguous. The increasing complexity of Medicare raises the question of whether cost savings associated with enrollment might be mitigated by the complexity of choosing the ideal plan for those with low health insurance literacy. In this study, I utilize the Medicare eligibility cutoff at age 65 to implement a regression discontinuity design that analyzes the impact of Medicare eligibility on household debt and out …

Integrating Feminist Approaches In Counseling Work With Adult Women, Kristen M. Toole

Adultspan Journal

The scope of ‘women’s issues’ in counseling is an ever-evolving landscape. Recent events such as the reversal of Roe v. Wade and the disproportionate impact of COVID-19 on women serve as powerful reminders of the necessity of this focus while underscoring a deep-rooted history of oppressive patriarchal structures. Therefore, counselors must remain informed of the unique considerations surrounding adult women in counseling and acquire proficiency in versatile techniques to meet this population’s nuanced needs. This article examines the complexity of contemporary womanhood and explores the fundamentals of Feminist Counseling Theory (FCT), a holistic, multiculturally conscious, social justice theory in counseling. …

Three Essays On Development Economics And Human Capital, Arpita Khanna

Dissertations and Theses Collection (Open Access)

In the first chapter, we estimate the impact of exposure to the 2015 Nepal Earthquake on intimate partner violence with two rounds of Demographic and Health Surveys data. Using differences-in-differences estimation, we find that exposure to the earthquake lead to a statistically and economically significant increase in intimate partner violence in the urban areas but not in the rural areas. This is possibly due to an increase in the stress felt by the victims. We also offer some evidence that the impact heterogeneity between the urban and rural areas is attributable to the differences in the reconstruction processes and assistance …

Using Machine Learning To Analyze Children’S Drawings As Indicators Of Mental Well-Being, Nicholas R. Lawrie

Master's Theses

Human figure drawings are a well-studied diagnostic tool for emotional distress in children. Cleft lip/palate is one of the most common birth defects in the world, and has been shown to negatively impact emotional well-being in childhood which can have negative economic consequences in adulthood. Utilizing a dataset of human figure drawings from children in India and survey data on mental health, this paper will assess the impact of corrective surgery on mental health outcomes, as well as assess the validity of the drawing emotional indicators themselves. The results indicate that while the emotional indicators may not be valid in …

Trade Liberalization And The Social Determinants Of Health: A Case Study Of Nafta's Impact On Mexico From 1994 To 2005, Maria Trubetskaya

Undergraduate Theses, Capstones, and Recitals

Given the increased transnationalization of borders and economic interdependence between countries in the Global North and South, it is imperative to address how these trends impact the health and well being of the populations involved. The conventional neoliberal economic framework, however, falls short in explaining these dynamics due to its overemphasis of proximal determinants of health as direct consequences of commodification and free market activities. In congruence with those theoretical limitations, there is a limited assessment of more distal determinants – the social determinants of health (SDOH) – that are arguably more consequential for health and are interrelated with the …

The Impact Of Afghan Opium Cultivation On The U.S. Opioid Epidemic, Zachary Wahab Cheek

UNL Student Research Days Posters, Undergraduate

I argue here that increases in Afghan opium cultivation, the most prolific in the world, has depressed American prescription opioid and heroin prices, thereby increasing abuse risk in U.S. addict populations and increasing death rates. Utilizing a two-stage regression model with a sparse dataset from several national and international sources, I find evidence that a one percent increase in Afghan opium production is associated with a 0.122 percent increase in prescription opioid overdose deaths, and a 0.367 percent increase in heroin overdose deaths. Assessing the 2001-2002 Taliban opium ban with an identification strategy, I find that in this timeframe prescription …

Temperature Effects On Prevalence Of Sexually Transmitted Infections Among At-Risk Female Sex Workers In India, Rajshri Suresh

Master's Theses

Vulnerability to climate change varies depending on the baseline climate, sensitivity to given exposure, and the presence of social, political, cultural, and institutional inequalities that influence access to essential resources of livelihood, particularly among informal labor market participants. Within the risky informal labor market, the transient nature of sex work implies that sex workers suffer disproportional losses in health, income, protection, and other aspects of general well-being as a result of the effects of climate anomalies. In this paper, I investigate the effect of temperature on the prevalence of sexually transmitted infections in a high-risk population of female sex workers …

From Self-Sufficiency To Import Dependence In The Republic Of The Marshall Islands: Data Issues And Challenges, Debra L. Claypool

Electronic Theses, Projects, and Dissertations

Although it appears likely that the profoundly asymmetrical political and economic relationship between the United States and the Republic of the Marshall Islands (RMI) has contributed to the abandonment of traditional agriculture, import-dependency, and a decrease in quality of life for the citizens of the RMI, limits in existing quantitative data make it impossible to model exactly how this occurred. Therefore, rather than seek to model this causal relationship, the researcher employed three existing ethnographic studies to establish a quantitative measure of the transformation itself. Using additional government documents to supplement the existing data, a measure of relative percentage of …

The Effects Of Eighth Years Of Compulsory Schooling Enforcement In Turkey, Muhammed Tumay

Dissertations, Theses, and Capstone Projects

This dissertation consists of two chapters that cover Education, Labor and Health Economics.

Chapter 1. Impacts of Compulsory Schooling Reform on Higher Education and Intergenerational Educational Mobility: we estimate the effects of an exogenous increase in mandatory schooling (5 years to 8 years of schooling), as a result of a change in compulsory schooling law, on higher education, potential intergenerational educational mobility, and labor market outcomes among women in Turkey. Our empirical strategy addresses a well-known identification problem where women’s years of schooling are endogenous to individual characteristics. The Law took effect in 1997, whereby girls born before January …

Trade And Health Linkages: A Global Panel Data Analysis Using The Gravity Model, Pallavi Panda

School of Business

This paper provides empirical evidence on the effect of trade openness on child health using the data from 171 countries between the mid-1990s to mid-2000s. Using an instrumental variable approach with a geographic gravity model framework, this study finds that a 1% increase in openness leads to a 0.2% decrease in infant mortality rates across countries, which at the sample mean is about 8 infant deaths per 1000 live births. The result is robust to country-specific time-invariant heterogeneity as well as outliers. The main channels of operation seem to be through increasing incomes, increasing health expenditures, and decreasing inequality.

Do Rural Health Worker Incentive Schemes Work? Evidence From Thailand, Pallavi Panda, Pasita Chaijaroen

School of Business

This paper studies supply-side health interventions, which increased the monetary incentives and number of health professionals in the Deep South provinces of Thailand, and provides evidence on the effectiveness of provision of primary care providers on the health care utilization of the community. We use a difference-in-differences approach to estimate effects of this policy on child health by evaluating the probability of immunizations in the policy affected areas using two rounds of the Multiple Indicator Cluster Surveys (MICS). We find that after the policy implementation, there is a decrease in immunizations that are given to children within 2 months and …

Estimating Predictors Of Mental Well-Being Through Analysis Of Children’S Drawings: The Case Of Syrian Refugees, Stephanie Smith

Master's Theses

There are currently over 65 million individuals that have been forcibly displaced globally. The cumulative trauma that comes from the refugee experience and exposure to violence has proven to have long-term negative psychological outcomes and thus negative impacts on human capital in the long run. Given that over 50% percent of the global refugee population are children, the ability to efficiently and accurately assess their mental well-being is of critical importance. Using data from over 2000 refugee children in Jordan, I use machine learning techniques to find key predictors of psychological distress, PTSD, and exposure to violence found in children’s …

The Effect Of Sex Of Firstborn Children On Attitudes Towards Intimate Partner Violence, Shuvam Rizal

Master's Theses

What are the different ways in which one’s life is influenced by the sex of their children? Is there an effect on how they view Intimate Partner Violence? If so, is there a difference in how the male parent is affected by the sex of his child than the female parent? Bodies of conflicting Social Sciences literature suggest having a daughter makes one both more and less likely to engage in Intimate Partner Violence. In this paper, I approach this question through the use of a Linear Probability Fixed-Effects model on Demographic Health Surveys (DHS) datasets, using data from the …
