Validating Hybrid Simulation Of Restaurant Noise With Real-World Data, Samuel Underwood

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

Restaurants exhibit noise levels that vary with occupancy over a typical operating day. When noise levels become excessive, customer comfort is diminished. While many previous works have surveyed noise levels in restaurants over short time intervals, there has been little work to comprehensively examine noise levels over a full operating day, while also tracking occupancy levels and thoroughly measuring unoccupied acoustical parameters. This dissertation work contributes to the existing body of restaurant acoustics work by measuring unoccupied and occupied acoustical conditions in 21 restaurants in the Midwest, correlating user reviews, scores, and crowdsourced noise levels measured in 943 venues in …

Evaluation Of Transportation Policy Effectiveness In The United States: Case Of Personal Electric Vehicles And Commercial Electronic Logging Devices, Hania Afzal

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

Together, electric vehicle (EV) adoption and the electronic logging device (ELD) mandate illustrate two dimensions of transportation technology policy: the first driven largely by environmental and market-based incentives and the second by safety regulation and compliance requirements. Examining these cases side by side for the United States allows for a more comprehensive analysis of how technology adoption unfolds under different policy regimes, offering insights into the broader relationship between policy design, industry response, and public outcomes. The commercial motor vehicle (CMV) sector presents a different but equally important policy challenge in transportation technology adoption. Unlike consumer passenger vehicles, CMVs are …

A Place To Perform: Designing Spaces For Student Artists Through Event Planning, Ava R. Jacobsen

Honors Program: Senior Projects (Public)

This thesis examines the creation of accessible performance spaces for student artists not enrolled in formal music programs. To address this gap, two First Friday events were hosted at The Gathering Grove in Lincoln, Nebraska, providing platforms for local student performers and engaging the community in live art experiences. The first event, an open mic night, highlighted the challenges of spontaneous performances, while the second, featuring designated performers, tested more structured event planning strategies.

Both events emphasized the importance of marketing, venue layout, audience engagement, and operational organization. Key lessons included the need for contingency planning, multi-channel promotion, and clearly …

Effect Of Novel Antimicrobial Compounds On Fungal And Bacterial Pathogens, Megan Wilderman

Honors Program: Senior Projects (Public)

Antimicrobial resistance is a growing concern in medicine¹ leading to a need for the development of novel compounds. Two compounds were tested in this study, 2-hydroxyethylhydrazine (HEH) and para-nitrophenyl-isocyanide (NPIC). HEH targets phosphatidylcholine (PC) production², and NPIC targets mitochondrial function³. Choline (Cho) is a compound that bypasses the inhibition of HEH through the Kennedy pathway.² Two-fold serial dilutions were conducted in 96-well plates to test the sensitivity of different bacteria to HEH and fungi to HEH and NPIC in different media types. A choline condition was also included in the HEH dilutions to test …

Robot Wingman: Using Ai To Assess An Employment Termination, Henry H. Perritt Jr.

Nebraska Law Review

Four major generative AI engines—DeepSeek, Claude, ChatGPT, and Grok—are useful legal analysis tools for employment law practitioners. This Article presents the results of an experiment in which a transcript of a hypothetical client interview involving potential disability discrimination, retaliation, and wrongful termination claims was submitted to each AI system. The accompanying prompts requested identification and assessment of viable legal theories. The experiment demonstrates that contemporary generative AI performs sophisticated legal analysis comparable to experienced associates, correctly identifying major employment law claims including ADA violations, Title VII discrimination, OSHA retaliation, FMLA interference, and workers’ compensation retaliation. All four engines successfully spotted …

Sticky Science In Court, H. A. Spitzer

Nebraska Law Review

Litigation routinely employs scientific evidence to aid judicial fact-finding and decision-making. This is especially important in areas like family law, where legal standards—such as the best interests of the child—often depend in part on scientific findings. Yet the legal system’s gatekeeping doctrines (Frye, Daubert, and Federal Rule of Evidence 702) apply primarily to expert testimony, leaving other pathways through which scientific evidence reaches courts largely unchecked. These other pathways include citations in briefs and opinions to non-peer-reviewed or non-scientific sources such as law reviews, treatises, and self-published materials, which often become outdated and are not well positioned …

Let Them All Grow: Protecting Nebraska's Intersex Youth From Medical Intervention, Jori Peters

Nebraska Law Review

The Nebraska Legislature passed the Let Them Grow Act on May 22, 2023, which prohibits minors from receiving gender-affirming care in Nebraska. This Note argues that the Act violates the Equal Protection Clause of the Fourteenth Amendment because it exempts intersex children—those born with ambiguous sex characteristics—from protections against unnecessary, irreversible, and nonconsensual medical procedures, while the Act protects those born with clearly male and female sex characteristics. This Note clarifies the distinction between the issues faced by intersex individuals and transgender individuals, and highlights the psychological and physical harms of early sex assignment surgeries. Further, this Note outlines the …

Carson V. Makin: Ending The Status-Use Distinction And Building A Foundation For The Emergence Of Catholic Charter Schools, Tyler Lyon

Nebraska Law Review

Over the course of its history, the United States has wrestled with a wide variety of issues that have tested the tension between the Establishment and Free Exercise clauses of the First Amendment. One such issue involves the extent to which religious schools can access public funds, which was addressed by the proposal of the Blaine Amendment on a national scale in 1875. The Blaine Amendment was intended to prevent religious groups from accessing public funds, and although it did not pass on a national level, it was adopted by many states.

However, some recent United States Supreme Court cases …

On Sovereignty, Outer Space, And Taxation, Erika I. Scuderi

Nebraska Law Review

This Article offers a comprehensive framework for States’ taxing powers in outer space. Beginning with an analysis of the legal status of airspace and outer space, the study addresses the taxation of commercial space activities, where traditional fiscal approaches of residence-based and source-based taxation break down. The discussion ultimately centers on Article VIII of the Outer Space Treaty, on which basis the present Article proposes the “Tax Jurisdiction by Registration Principle,” arguing that the act of registering a space object provides a legal basis for taxing income derived from its use. In doing so, the Article provides for a potential …

Leveling The Playing Field: Which Type Of Political Gender Quota Most Effectively Increases Women's Legislative Representation?, Meghan K. Stone

Honors Program: Senior Projects (Public)

Significant advances have been made in recent years in terms of increasing the representation of women in national legislatures around the world. Many scholars believe political gender quota laws are responsible for this increase. However, it is important to note that there are several different types of political gender quota laws, each with differing mechanisms for increasing the presence of women within the legislature. This paper researched the effectiveness of three different systems of political gender quotas (voluntary political party quotas, legislated candidate quotas, and the hybrid system of quotas) in increasing the percentage of women represented within national legislatures …

Three Butterfly Genera Across The Central Texas Suture Zone, Qian Cong, Jing Zhang, Jinhui Shen, Leina Song, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

Genome-scale analyses of butterfly specimens across the Central Texas Suture Zone revealed that several taxa currently treated as subspecies exhibit genomic differentiation similar to that observed between species. Further investigation and genomic sequencing of additional specimens from across the ranges of these taxa support this conclusion and result in the following changes to nomenclature and taxonomy. Two new subspecies of Nymphalidae Rafinesque, 1815 are described: Asterocampa louisa monterra Grishin, ssp. n. (type locality in Mexico: Nuevo León) and Asterocampa clyton plana Grishin, ssp. n. (type locality in USA: Texas, Denton Co.). The following taxa are recognized as species, not subspecies: …

Feasibility Of Using Recycled Waste Plastic In Concrete Pavements In Nebraska, Amasi Hajahja, Jamilla Teixeira, George Morcous

Nebraska Department of Transportation: Research Reports

Waste plastic (WP) is a growing environmental concern due to its non-biodegradable nature, large-scale production, and harmful impact on natural resources. With nearly 75% of WP in the U.S. ending up in landfills, effective recycling strategies are urgently needed. In parallel, the limited availability of natural aggregates highlights the need for alternative materials in concrete construction. This study investigates the feasibility of using recycled waste plastic (RWP) in concrete mixtures, both as aggregates and fibers for rigid pavement applications in Nebraska. Concrete mixtures were prepared by partially replacing natural fine aggregates with recycled plastic aggregates (RPA) at replacement levels of …

Spatial Variability Of Nitrates And Nitrogen Mineralization Kinetics And Their Effects In Long-Term Tillage Systems, Bibash Rokaya

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Nitrogen (N) and water management are essential for water quality protection and crop production. However, soil N and water are spatiotemporally variable. Soil water spatial dependencies are described in the literature with known associations with preferential flows among other factors. In contrast, a knowledge gap exists on the spatial dependence of soil N mineralization kinetics. We hypothesize that soil N mineralization kinetics and soil water have distinct and cross-correlated spatial characteristics among soil management practices and climatic regions. For the field study, we measured soil-N mineralization kinetics, volumetric water content (VWC), and a suite of soil properties along ~70 m …

Evaluation Of Publicly Available Maize Germplasm Adaptation To Environments In Nebraska, Garrett Snodgrass

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Publicly available maize germplasm represents an important resource for breeding programs seeking to expand genetic diversity and improve hybrid performance. However, effective use requires characterization of per se phenotypic performance of parental lines and evaluation of the parental line’s hybrid progeny adaptation to a given target population of environments. Furthermore, understanding population structure and heterotic grouping is imperative for maximizing efficiency of breeding decisions. The objectives of this study were to (1) evaluate phenotypic performance of parental lines and hybrids across environments in Nebraska, and to (2) refine heterotic group classification of parental lines within the University of Nebraska-Lincoln’s Hybrid …

Dressing For The Descent: Costume Designing Eurydice, Hannah Olivia Schoen

Johnny Carson School of Theatre and Film: Theses, Student Research, and Creative Work

During the early spring of my second graduate year, I was assigned to be costume designer for the upcoming production of Sarah Ruhl’s Eurydice. Eurydice is a retelling of a narrative that had been mostly given spotlight to the male hero in past iterations. Now we as a design team were going to tell the story from Eurydice’s point of view. After doing an analysis and research into details that would give me ideas on how I wanted to present these characters, I was able to present initial ideas to the director at our first design meeting.The design process …

The Social And Biological Frontiers Of Polio: Comparing Global Eradication Strategies, Srisai A. Turangi

Honors Program: Senior Projects (Public)

This paper provides a comparative analysis of the divergent global strategies for poliomyelitis (polio) eradication, examining the historical and structural contexts of developed nations – the United States and United Kingdom – alongside the enduring challenges in endemic regions such as Nigeria and Pakistan. Biomedical innovations like the Inactivated Polio Vaccine (IPV) and Oral Polio Vaccine (OPV) have helped bring the world to a state of almost complete global eradication, but progress is still uneven due to variations in funding, healthcare infrastructure, and the legacy of colonialism. Studies reveal how a framework where global health inequalities remained, allowed for resource-rich …
