Environment-Based Constructivism Learning To Increase Elementary School Students' Awareness Of Social Change, Dina Diana

Jurnal Pendidikan Humaniora

Social and natural science learning in primary schools should enable students to understand social change as a phenomenon closely connected to their daily lives. However, teacher-centered classroom practices often limit students’ ability to relate social concepts to their local environment. This study aims to describe the implementation of environment-based constructivist learning to improve fourth-grade students’ awareness of social change, analyze its success indicators, and identify supporting and inhibiting factors. A descriptive qualitative design was employed involving 20 fourth-grade students at SDN 2 Karang Jati. Data were collected through oral questioning, classroom observation, simple community interviews, documentation, observer notes, and student …

Experimentation, Adaptability, And Ingenuity In The Community Art Studio, Louisa Mary Drab May 2026

Experimentation, Adaptability, And Ingenuity In The Community Art Studio, Louisa Mary Drab

Expressive Therapies Theses

To examine the question, “How can community art making in an open studio embolden women through creative adaptability, ingenuity, and experimentation?” a mosaic project was conducted over four sessions with women attending an art studio at a day shelter. Current literature illustrates the scope of success open studio has had in promoting community connectivity through the communion of individuality. The expressive therapies continuum, open studio approach, trauma-informed care, and the therapeutic alliance are the pillars that informed this exploration. This community engagement project melded together structural components of mosaic-making with the tenets of open studio, where guiding and sharing are …

Wet tropical forests are experiencing rising temperatures and increased frequency and intensity of extreme climatic events, such as cyclones, which can increase rates of soil erosion and surface runoff. Fungal litter mats, formed by agaric decomposer fungi, play a crucial role in stabilizing slopes, preventing erosion, and aiding nutrient cycling; however, little is known about how warming affects litter mat growth and function. We investigated two litter mat-forming fungi, Gymnopus johnstonii and Marasmius aff. crinis-equi, in warmed (+4°C above ambient) and control plots in the Luquillo Experimental Forest, Puerto Rico. Growth and time-to-leaf colonization were monitored over 6 weeks …


Improving Nursing Compliance With Pressure Injury Prevention In Postoperative Patients In The Cardiovascular Intensive Care Unit, Chingyi Lam May 2026

Improving Nursing Compliance With Pressure Injury Prevention In Postoperative Patients In The Cardiovascular Intensive Care Unit, Chingyi Lam

Doctor of Nursing Practice Final Project Abstract

Pressure injuries acquired in the hospital continue to be a major concern in patient safety among critically ill populations. The purpose of the quality improvement project was to improve nursing compliance with pressure injury prevention strategies among postoperative patients in a cardiovascular intensive care unit (CVICU). Patients who undergo cardiovascular surgery are at a high risk of developing pressure injuries due to immobility, sedation, vasopressors, and prolonged positioning on their backs. The quality improvement project was carried out in a 37-bed CVICU using the Institute for Healthcare Improvement (IHI) Model for Improvement and Plan–Do–Study–Act (PDSA) cycles. Data on nursing repositioning …

Higher predicted brain age difference has been associated with several psychiatric disorders. Generalized anxiety disorder (GAD) is associated with markers of accelerated aging. In this study, we determined brain predicted age difference (PAD) in individuals with GAD and healthy controls (HC) as well as group differences in PAD variability using voxel-wise structural MRI. The training dataset included 3511 controls, and the testing dataset included 1595 individuals with GAD and 4552 HC from the ENIGMA-Anxiety GAD Working Group. A convolutional neural network model using four input modalities per subject and a model ensemble approach was used to predict brain age. The …

Hidden Behind Happiness: Bhutan’S Global Image And Ethnic Exclusion, Deepesh Das Shrestha May 2026

Hidden Behind Happiness: Bhutan’S Global Image And Ethnic Exclusion, Deepesh Das Shrestha

Master's Theses

Bhutan has gained international recognition for its philosophy of Gross National Happiness (GNH), which promotes holistic development through principles of well-being, environmental sustainability, cultural preservation, and good governance. Yet this celebrated image conceals a darker history: the systematic expulsion of the Lhotsampa, the Nepali-speaking ethnic minority of southern Bhutan. This study critically explores the contradiction between Bhutan's international image as a model of happiness and the lived experiences of Lhotsampa refugees who were displaced during the early 1990s.

Using a qualitative phenomenological research design, the study draws upon in-depth semi-structured interviews with six resettled Bhutanese Lhotsampa refugees living in the …


The Impact Of Sovereign Wealth Funds On Emerging Markets: A Behavioral Analysis Of Investment Decisions And Market Reactions, Grant A. Mosshart May 2026

The Impact Of Sovereign Wealth Funds On Emerging Markets: A Behavioral Analysis Of Investment Decisions And Market Reactions, Grant A. Mosshart

Senior Honors Theses

Sovereign Wealth Funds (SWFs) are increasingly influential in emerging markets, yet the behavioral drivers behind their investments remain underexplored. In this paper, an analysis of SWF capital’s impact on economic development and the psychological factors, such as optimism bias and herding, that shape these decisions is examined. Utilizing a mixed-methods comparative study, the research analyzes Saudi Arabia’s Public Investment Fund (PIF) and Singapore’s Temasek Holdings. Event study analysis reveals a divergent impact: the PIF’s high-profile developmental commitment to India generated a positive 5-day Cumulative Abnormal Return of +2.05%, confirming a macro-level “seal of approval” signaling effect. By contrast, Temasek’s commercially …

Christov

Michigan Tech Publications

Non-heme Fe(II)/2-oxoglutarate (2OG)-dependent halogenases catalyze highly selective C-H halogenation. BesD is a non-heme Fe(II)/2OG halogenase that performs regio- and stereoselective chlorination of the l-lysine (l-Lys) substrate. Understanding the mechanism by which halogenation is favored over canonical hydroxylation is essential for guiding enzyme engineering efforts aimed at converting hydroxylases into halogenases. Here, we combine molecular dynamics (MD) and hybrid quantum mechanics/molecular mechanics (QM/MM) calculations to elucidate the origin of chlorination selectivity in BesD and variants derived from a homologous hydroxylase. Our results indicate that, although the initial inline Cl-Fe(III)-OH intermediate is inherently predisposed toward hydroxylation, it undergoes a two-step isomerization in …


Field Monitoring And Geometric Representation Of A Uhpc-Repaired Bridge Structure, Robert Lawler May 2026

Field Monitoring And Geometric Representation Of A Uhpc-Repaired Bridge Structure, Robert Lawler

Honors Scholar Theses

Ultra-High Performance Concrete (UHPC) has shown promise in bridge rehabilitation broadly, but its application to steel gusset plate repair represents a novel use case with limited prior research. Therefore, when the Commodore Isaac Hull Bridge in Derby, Connecticut, was issued an emergency declaration due to gusset plate section loss, a UHPC repair was implemented. This project represented the first known field implementation of this type of UHPC gusset plate repair, marking a significant advancement in the rehabilitation of deteriorated steel bridge components. To support long-term performance assessment and ensure the success of the repair, field monitoring efforts were also incorporated …

A Stadium In Our Backyard: Community Participation In Stadia Redevelopment Projects, Sofia Zazueta

Master's Theses

The Santiago Bernabeu in Madrid, Spain and the Chase Center in San Francisco, California are two stadium redevelopment projects that exemplify the stakeholder dynamics that come into play when developers pitch a multipurpose stadium located a few blocks away from people’s backyards. Urban development patterns must be in constant evolution to meet the needs and demands of the current generations. In cities, stadia redevelopment projects have entered the picture to reimagine the role that these structures once played. The stadium once used for the sole purpose of holding matches has become a venue that now hosts different events such as …


Middle Management Diplomacy: An Examination Of Us Foreign Policy Analysis In Middle-Echelon Diplomatic Professionals, Isaac R. Silvino May 2026

Middle Management Diplomacy: An Examination Of Us Foreign Policy Analysis In Middle-Echelon Diplomatic Professionals, Isaac R. Silvino

Master's Theses

This study analyzes the role which managerial level U.S. military Foreign Area Officers and Foreign Service Officers play in shaping and implementing U.S. foreign policy. By analyzing the individual professional at the middle-echelons of an organizational hierarchy, we make an effort in dispelling ourselves from obscured perceptions of IR centered on character and state idealization driven narratives. Doing this may help bridge the foundational gap between academics and practitioners while shifting towards a paradigm of IR analysis focusing on human agency and decisions.

Result

Individual managerial echelon diplomats do not directly make policy, but rather play a crucial role in …

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 Feather Of The Quill: How Folklore Shapes Human Relationships With Wildlife, Taylor Breeanne Nelson May 2026

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. …


Herd Conditions And Food Security: Evidence From Kenya, Kira J. Enriquez May 2026

Herd Conditions And Food Security: Evidence From Kenya, Kira J. Enriquez

Master's Theses

Food insecurity is worsening across Kenya's Arid and Semi-Arid Lands, where over three million people currently face acute hunger. Among pastoral communities in these regions, livestock are the central productive asset and primary food source. When herds deteriorate, households face falling milk production and the erosion of assets that would otherwise buffer consumption during difficult periods. This paper tests whether livestock body condition and rangeland forage quality predict household food coping behavior, and whether those relationships differ above and below a Micawber-style herd size threshold. Using a panel of 232 pastoralist households surveyed across five ASAL counties between 2021 and …


The Effects Of War Exposure On Psychological Well-Being And Social Preferences, Jacinta B. Duncan May 2026

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 May 2026

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 …


Urban Green Space As Climate Infrastructure, Wyatt W. Del Valle May 2026

Urban Green Space As Climate Infrastructure, Wyatt W. Del Valle

Master's Theses

This thesis estimates the causal effect of urban parks on land surface temperature in the

American Southeast using a geographic regression discontinuity at park boundaries. The

result is null. Within a CCT-optimal 257-meter bandwidth across five cities, park interiors

are not detectably cooler than the land immediately outside them:−0.023 °C, p = 0.926.

A two-way fixed effects panel across 20 cities and 39 years confirms the well-documented

NDVI–LST relationship—a 0.1-unit increase in NDVI is associated with 3.4 °C lower surface

temperature—while a park size heterogeneity model runs directly into the siting endogeneity

problem, showing why naive distance gradients cannot be …
