The Interaction Of Income Inequality With Road Maintenance Expenditure In Terms Of Effect On Regional Economic Development, Chigoziem Munachiso Uzoigiwe

All Dissertations

Persistent income inequality and deteriorating infrastructure continue to challenge balanced economic development across U.S. regions, raising questions about how public investment can be optimized to address both. Therefore, this study examined the interaction between income inequality and road maintenance expenditures in driving economic growth in the United States. I analyzed whether road maintenance can offset the adverse effects of inequality on regional growth and whether the benefits of such infrastructure investment vary with the level of inequality. Using state-level panel data on GDP, infrastructure spending, income inequality, education, and other socioeconomic indicators, I estimated the direct and interactive effects of …

An Empirical Investigation Of The Effects Of Gunshot Detection Technology In Detroit, Joe Davis

All Graduate Reports and Creative Projects, Fall 2023 to Present

This paper evaluates the impact of acoustic gunshot detection technology (GDT) on crime and policing outcomes in Detroit, Michigan. Leveraging the implementation of ShotSpotter across high-crime neighborhoods, I analyze outcomes including crime rates, emergency calls, police response times, and case clearance. My findings indicate that ShotSpotter installation is associated with a 6% reduction in violent crime but a modest increase in nonviolent crime. The technology also produces a large increase in the reporting of gunfire incidents—over 300% more gunshot-related calls for service—yet police respond 7% slower to ShotSpotter alerts than to citizen-reported gunshots. Consistent with prior research, I find no …

White Horse Village: A Northern Utah Ufo Narrative, Melissa Petersen

All Graduate Reports and Creative Projects, Fall 2023 to Present

In the early 1960's a group of UFO believers, called Christ Brotherhood Inc., established themselves in Smithfield Canyon, UT and called their commune White Horse Village. A main house was built where the leader of the group lived and two or three smaller cabins were erected for the believers. Without running water they used an outhouse among them and built a small church where they would meet for lectures. Their beliefs centered around the popular movement of New Age spirituality of the time, which included scientific explanations for Christian beliefs including a belief in benevolent aliens as modern angels.

Unmixing In Very High Spatial Resolution Hyperspectral Images, Ana C. Chavez Lopez

Open Access Theses & Dissertations

Hyperspectral Imaging (HSI) captures hundreds of contiguous narrow wavelength bands across the optical region of the electromagnetic spectrum collecting the spectral signature of materials in the field of view of the sensor enabling detailed analysis of each pixel's spectral signature. Satellite or airborne remote sensing systems often capture imagery with low to moderate spatial resolution (LMSR). At these resolutions, the measured spectral signature is a mixture of the signatures of the materials within a single pixel. This mixing of spectral information makes analysis and material identification difficult. Hyperspectral unmixing is an analysis technique that decomposes a pixel's spectrum into constituent …

Reconstruction And Texturing Of 3d Surfaces From Fused Low-Cost Aerial Lidar And Optical Imagery, Samuel Kiguthi

All Graduate Theses and Dissertations, Fall 2023 to Present

Drones equipped with laser scanners (LiDAR) and cameras capture detailed 3D scenes. Combining the laser points with photos builds realistic, photo-textured 3D maps used in surveying, agriculture, and infrastructure planning. Conventional methods to create these maps often misrepresent inward shapes such as doorways, overhangs, and outcrops. These shapes are misrepresented because drones mainly view top surfaces and do not collect significant data on vertical or hidden areas.

This study introduces a surface-reconstruction method that groups LiDAR points into clusters, reconstructs smooth surfaces for each cluster, and uses information from recorded camera poses to stitch clusters together. Tests on real drone …

Physics-Guided Strategies For Enhancing Neural Networks Trained With Limited Data, Jose Guadalupe Perez Zamora

Open Access Theses & Dissertations

Deep neural networks excel at a wide range of processing tasks across various disciplines. However, the quantity and quality of data significantly impact network performance. In specialized domains, high-quality datasets are often difficult to gather, interpret, and curate for effective learning. Few-shot learning techniques, including transfer learning, data augmentation, and meta-learning, have emerged to address these constraints.

We propose three physics-guided strategies for enhancing neural networks trained with limited data: (1) combining existing models like LSTMs with Physics-Informed Neural Networks through two-branch architectures that merge their outputs, (2) deriving custom physics-informed data augmentation algorithms to expand limited datasets, and (3) …

School of Geography, Earth and Environmental Sciences

This study presents the first cradle-to-grave life cycle assessment (LCA), focusing exclusively on environmental impacts, comparing electric and petrol-powered rigid inflatable boats (RIBs) under low-usage recreational and high-usage harbour-master scenarios. The study follows ISO-compliant LCA methodology and emphasizes transparency in data and assumptions. Ten environmental impact categories were analysed, including global warming potential (GWP), particulate matter formation, acidification, eutrophication, ecotoxicity, and resource scarcity. Results show that switching to electric RIBs reduces GWP by 34 % for recreational and 52 % for harbour-master scenarios, despite higher production-phase impacts across all categories. The electric RIB delivers notable operational benefits in GWP and …

Assessing Native Tallgrass Prairie Species As Main Roadside Vegetation In Arkansas, Sarah Paschal

Graduate Theses and Dissertations

Tallgrass prairies are among the most endangered ecosystems in North America, with Arkansas having lost over 99% of its native grasslands. This research evaluated the potential for using native tallgrass prairie species in Arkansas roadside vegetation. Two field experiments were conducted from 2022 to 2024. The first assessed seven native seed mixtures at three roadside locations (Clarksville, Huntsville, and Newport). Seed mixture composition significantly influenced establishment outcomes, with early-establishing forbs such as black-eyed Susan, partridge pea, and Illinois bundleflower performing well, though establishment varied by location. A second trial compared planting date (Autumn, Winter, Spring) and planting method (broadcast, drill …

From Student Project To Research Agenda: How Libraries Facilitate Gis Education And Collaboration, Charidy Paige, Jeanine Finn

Library Staff Publications and Research

Geographic information systems (GIS) have been a tool and methodology deeply
intertwined with academic libraries since the initial efforts of ARL and ESRI to support the development of map librarians into geospatial data experts in the early 1990s.
Although GIS in libraries has been a source of successful collaborations, the demands are often overwhelming for library staff. Over time, the scale, formats, and methods of data sharing have evolved significantly, requiring skills beyond many traditional library competencies.

Teaching For Global Ecological Citizenship: A Case Study Of Rural Teachers’ Experiences And Practices, Sarah L. Tennyson

Dissertations

The purpose of this qualitative case study is to examine the experiences and practices of rural educators incorporating global ecological citizenship education into the social studies classroom. The systematic themes of social studies education in the past must evolve with the diversity of the classroom. Traditional themes taught must become more globally relevant, including ecological citizenship, the responsibility of citizens to sustain and participate in global ecological issues. One on one interviews with four rural Georgia educators along with artifacts they provided were examined for themes related to two research questions. How do rural educators adapt their instructional strategies to …

Defending The Homeland: An Archaeoethnodemographic (Aed) Analysis Of Population Dynamics And Settlement Patterns In The Navajo Dinétah, Ad 1720–1745, Kurt Mantonya

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This dissertation presents an innovative archaeoethnodemographic (AED) analysis of Navajo population dynamics during the Middle Period (AD 1720−1745) of the Gobernador Phase in the Dinétah, the ancestral Navajo homeland in northwest New Mexico. During this critical quarter-century, intensified Ute and Comanche slave-raiding and Spanish military expeditions forced the Diné to abandon traditional dispersed settlement patterns in favor of defensive aggregation around fortified pueblitos—small masonry defensive structures built on boulder-tops and mesa-rims throughout the region.

The study employs an AED framework that systematically integrates archaeological site analysis, ethnographic household organization data, historical documentation, and demographic modeling to reconstruct population dynamics during …

Detecting Prescribed Fire, Haying And Grazing Events Via Remote Sensing To Create Grassland Disturbance Landcovers For The Ring-Necked Pheasant (Phasianus Colchicus), Megan Amy Baldissara

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This dissertation developed disturbance detection models to fulfill the need for remote sensing landcover products describing grassland structure. The use of landcover products derived from remote sensing is increasing over time in pheasant (Phasianus colchicus) research. Such landcover, however, does not provide relevant pheasant structural habitat information (Chapter 1). Pheasants require tall, high-density grassland for nesting, tall grassland with medium density for brood rearing, and tall grassland for wintering. Time since disturbance can serve as a proxy for structure, as it shapes vegetation by removing biomass and resetting succession. Disturbance is easier to detect than structure with current …

Deepening Our Understanding Of Resilience: How Evaluation Can Contribute, Michael Quinn Patton

The Foundation Review

Resilience is the capacity to experience a significant shock and adapt as needed to survive and move forward. The current age is one of constant system shocks economically, environmentally, and politically. Resilience becomes essential for navigating these and other risks.

Individuals, organizations, communities, and ecosystems manifest different degrees and types of resilience requiring appropriately matched evaluation responses. In considering new directions for philanthropic evaluation, this article offers for the first time an overarching framework of four different responses to system shocks and disruptions. This leads to four different evaluation criteria: continuity, adaptation, innovation, and capitulation.

In addition to the long-term …

National Hero And Water Deity: The Worship Of Triệu Việt Vương In The Red River Delta, Vietnam, Huong Thi Nguyen

Graduate Theses and Dissertations

In my dissertation, the theory of collective memory will be deployed to address many questions regarding retaining, recovering, and re-creating the worship of King Triệu Việt Vương. He was a legendary, historical king of Vietnam who supposedly lived in the 6th century. His achievements were connected to the people living in the Red River Delta in their fight against the Liang invasion. The villagers who lived near or in this area also honored him for his spiritual power. They built a small temple/ shrine right by the riverbank to worship this King. The Vietnamese dynasties, Ly (in the 11th century), …

Archetypes Of Ai Adoption: A Snapshot In Time Of Philanthropic Practice, Grace Lyn Higdon, Linda Raftree

The Foundation Review

The authors identified four archetypes describing philanthropic funders’ approach to AI: The Curious, The Doers, The Dreamers, The Skeptics.

The authors did not find major differences found across foundations based on their geographic location, though there were differences found based on their mission and values. Feminist and social justice funders in the Global South demonstrated more skepticism than others.

Even in seemingly benign or straightforward applications, AI systems demonstrate unpredictable behavior, leading to most foundations proceeding with caution.

The rapid pace of AI has meant that formal AI policies are rare, though foundations align on some common “red lines” that …

The Ai Contributor: A New Thought Partner In Systems Change, Jewlya Lynn, Rachel Reichenbach

The Foundation Review

Many foundations are making long-term commitments to advancing systemic change, continually adapting and refining their approaches along the way. An emerging and often underutilized tool in their systems change toolkit is generative artificial intelligence (AI).

AI is enhancing practices across philanthropy, often focused on increasing efficiencies and scaling or streamlining human tasks. What if we instead focus on what AI can do that is distinctly different from what a human can offer? In the world of systemic change, we continue to struggle with the complexity and intractability of systems and finding moments when systems can be shifted. AI can be …

Base Building Evaluation: Three Opportunities To Improve Its Use And Relevance, Katie Fox, Margaret A. Post

The Foundation Review

The concept of base building comes from the traditions of electoral and labor organizing, where organizers focus on drawing leadership from a specific constituency or geography. Base building is foundational to organizing efforts. It involves the recruitment, training, and leadership development of people who are often most directly impacted by the issues and causes that organizing focuses on.

In recent years, base building has seen increased interest and investment from the philanthropic sector as funders recognize base building as critical to community-led change. As funders expand their investment in base building, they increasingly seek information and data about base building …

When Shift Happens: Navigating Toward A Framework For Responsible Philanthropic Exits, Laila Bell, Stephanie Teleki, Jaime Vazquez

The Foundation Review

Philanthropy can be a powerful force for social change, with influence extending far beyond the funding period. When foundations decide to cease funding in a specific area, how they exit can significantly impact the field they are leaving in both the short- and long-term. A poorly executed exit risks blindsiding grant partners and communities, damaging key relationships, undermining progress, and potentially leaving the field worse off than it was found. In contrast, a responsible exit can help the work continue long after the foundation ceases its funding.

What defines a responsible exit? In this article, learning leaders at three different …

Philanthropy As Risk Capital: Shaping Trust And Learning At The Speed Of Ai, Nina Sabarre, Clara Bennett, Laura Chavez-Varela

The Foundation Review

As artificial intelligence rapidly reshapes society, philanthropy is increasingly called to act as "risk capital" for the public good. But risk alone is not enough. Without rigorous, field-wide learning, philanthropy's bold bets may remain isolated and short-sighted, failing to catalyze the systemic change this moment demands.

This article draws on three sources of learning at Omidyar Network—an evaluation of The Tech We Want initiative, external strategy consultations with 29 stakeholders, and early learnings from a generative AI portfolio—to identify how philanthropy can uniquely "de-risk" AI innovation for collective benefit.

Through trust-based partnerships, ecosystem infrastructure support, and narrative change, these learning …

Universal Systems Simulation Via Constraint Hypergraphs With Applications To Digital Twins, John Morris

All Dissertations

The characterization of systems encompasses a variety of modeling frameworks designed to capture specific behaviors and components of various system domains. Whatever the framework, the core elements of a system representation are the information of the system and a description of how that information is related. The relations in deterministic systems are functions, which, when composed to form executable processes, can be used to simulate system data. A declarative modeling framework is one that encodes mechanisms for preparing these simulations within the model structure, allowing an external agent to form the execution processes required for a given context. To date, …

"Forgive Our Living And Our Dead": Colonial Warfare In The Philippines, Mattie Fitzpatrick

History

In March of 1906, American troops massacred over 1,000 Filipino civilians on Bud Dajo mountain. American service members were commended for this incident. My research examines this massacre to ask why wars of insurgency are specifically subject to abuses of power, particularly during the American-Philippines War and the ensuing colonial warfare between 1898 and 1906 under the colonization of the US. My research will focus on the circumstances created to excuse US soldiers after atrocities were committed and the colonial attitudes of the time in addition to the brutal methods used by the American government in Philippines. American colonial administrators …

Using a modified grounded theory approach and a feminist lens, this study examines women’s psychosocial experiences, their evolving political consciousness, and their active roles in humanitarian, cultural, and cyber resistance.Findings reveal that the war simultaneously reinforced and disrupted traditional gender expectations. While Ukrainian women dealt with increased domestic and caregiving burdens …

Female Politicians And Corruption In Rural India, Somdeep Chatterjee, Shiv Hastawala, Elisa Taveras

School of Economics and Finance Faculty Publications

This paper leverages random assignment of female quotas for leadership positions on Indian village councils to assess its causal effect on corruption. Since the mid-1990s, India has mandated that at least one third of village council chief positions be randomly reserved for women. Using data from the Rural Economic and Demographic Survey (REDS) 2006, we find that an additional term reserved for a female head as opposed to just a single one reduces both the occurrence and bribe amounts paid to the local government by households. This reduction is also observed in bribes paid to other local officials suggesting downstream …
