Unleashing Stress: The Effects Of Training, Bond Strength, And Stress On Pet Dog Behaviors And Health, London Maria Wolff

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

Humans and dogs have formed a unique ability to communicate with each other through evolutionary and developmental mechanisms. This increased communication serves to form dynamic interspecies bonds by facilitating learning and training over the lifetime of a dog. However, it is not known what factors permit the unique capacity of dogs to form bonds with, and learn from, their human companions. Odor is a notable candidate for interspecies communication about emotional states, with studies showing that both dogs and humans use odor information to detect human emotions (Calvi et al., 2020). Possibly, this may include detection of both acute and …

Problems With Small Drinking Water Systems In Developing And Developed Countries: How Do They Compare?, Kurt Kesteloot

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

This dissertation compares the factors that drive the long-term functionality of small drinking water systems (serving fewer than 10,000 people) in developing and developed country contexts, with a focus on groundwater supplies. Using regression analysis in SAS and complementary fuzzy-set Qualitative Comparative Analysis (fsQCA) for developing countries, the study integrates two datasets: 23 Engineers Without Borders project surveys (90+ variables across 14 countries) and a multi-year National Park Service inspection dataset (approximately 1,561 systems; 7,460 recorded deficiencies, enriched with U.S. Census ZIP-code aggregates). In developing countries, statistically significant predictors of success include government cash contributions (odds ratio [OR] ≈ 67.6), …

External Force Control Of Transitional And Turbulent Flows, Cesar Alberto Leos

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

Turbulence in wall-bounded flows governs momentum transport, drag, and energy efficiency in a wide range of engineering systems, yet its response to external forcing remains incompletely understood across transitional and high Reynolds number regimes. This dissertation investigates an active flow control strategy based on spanwise external forcing and demonstrates how it modifies the dynamics of transitional and turbulent channel flows with the objective of identifying the mechanisms through which forcing alters transition, flow physics, and turbulent drag reduction.

Firstly, direct numerical simulations are performed to examine the subcritical transition under external forcing. The onset and sustenance of turbulence are shown …

Laser Microprocessing Of Metallic And Composite Materials: Nanosecond Pulsed Laser Surface Melting, Laser Shock Peening, And Femtosecond Laser Machining, Qiuchi Zhu

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

This dissertation comprises three parts addressing laser microprocessing of metallic and composite materials through nanosecond pulsed laser surface melting, laser shock peening, and femtosecond laser machining. The first part discusses nanosecond pulsed laser surface melting for corrosion mitigation in stainless steel. Commercial 304 stainless steel (SS) was first used to establish a processing window for stable shallow remelting and rapid resolidification. The approach was then extended to 304L/308L SS welded joints relevant to nuclear dry storage canisters. The results show that nanosecond laser surface melting refines the near-surface microstructures in the heat-affected zone and improved pitting corrosion resistance. Electrochemical and …

Carmen Manrique De Quintero: A Forgotten Legacy In Colombian Piano Music, Lina Maria Luisa Marín Diaz

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

This doctoral document investigates the life and piano works of Carmen Manrique de Quintero (1871–1931), a pivotal yet overlooked figure in Colombian music history. Positioned as a stylistic bridge between the nineteenth-century estética del salón [salon aesthetics] and the professionalization of the Colombian composer, Manrique de Quintero’s output represents a sophisticated synthesis of European forms and Colombian national rhythms. Despite her membership in the influential Garay artistic lineage and her prolific body of work, her legacy has suffered from editorial blurring, fragmented documentation, and systematic intellectual appropriation. Using a multidisciplinary approach of genealogical reconstruction and artistic archaeology, this study restores …

Enhancing Soybean Breeding Through Optimized Testing Networks And Sparse Designs, Arthur Martins Almeida Bernardeli

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

This dissertation addresses a central challenge in soybean breeding: how to make better selection decisions across diverse environments while working within the practical limits of field testing. Multi-environment testing is essential for evaluating breeding lines, but large testing networks are costly to maintain and difficult to interpret because genotype performance often changes across locations and years. At the same time, breeders must decide how to allocate limited field resources while still capturing the environmental and genetic variation needed for effective selection. Using yield, pedigree, genomic, and environmental data from the University of Nebraska–Lincoln Soybean Breeding Program, this dissertation explores practical …

Transitional And Turbulent Dynamics In Viscoelastic Wall-Bounded Flows, Alexia Martinez Ibarra

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

The addition of small amounts of long-chain polymers to a turbulent flow has been reported to modify the flow phenomena when compared to Newtonian flows, resulting in a significant skin-friction reduction. Although polymer-induced drag reduction has been extensively studied through both experimental and numerical studies, a unified and predictive understanding of the phenomenon is still lacking. This dissertation focuses on better understanding of this phenomenon, particularly on the transitional regime, which remains largely unexplored but is of utmost importance for both practical and fundamental purposes.

Firstly, direct numerical simulations are performed to study the effect of polymers on the laminar-turbulent …

On The Transport Of Chloroplast Lipids, Cailin Smith

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

Chloroplasts are green, photosynthetically active organelles ubiquitous to the plant kingdom. Owing to their cyanobacterial origin, chloroplasts consist of three membranes: the outer envelope, the inner envelope, and the thylakoid, the latter of which is the site of the light-dependent reactions of photosynthesis. Not only do the lipids that make up these membranes delineate aqueous compartments, but they also respond dynamically to developmental and environmental cues, constitute the matrix that scaffolds protein machinery, and even serve as functional components of some proteinaceous complexes. However, while lipids are of vital importance to the structure and function of the chloroplast, the mechanisms …

Awareness, Protest, And Action: Women Science-Fiction Writers As Writer Activists, Carolyn Nolte

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

Following the end of World War II, science-fiction literature, which was mostly dominated by white male writers, experienced an increase in stories written by women writers. Of these postwar stories written by women, the three women writers in this dissertation imagined how their present-day experiences informed the future by exploring their concerns about humanity’s collective trajectory. By analyzing how their stories dramatize possible future social, psychological, biological, and environmental harms, this dissertation argues that these women writers’ works distinguish them as writer-activists, a concept I borrow from Rob Nixon’s work Slow Violence and the Environmentalism of the Poor.

I …

Costa Rican Oboe Music By Mario Alfagüell: A Performance Guide, Ruth Moreno Calderon

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

It was not until 1972 that the modern oboe achieved a formally established professional presence in Costa Rica. This does not suggest that the instrument was absent from the country prior to this date; rather, its professional consolidation occurred with the arrival of two foreign oboists (Claudio Bondy and David Busch) and whose activities marked the beginning of systematic performance, pedagogy, and institutional continuity. As a result, the professional history of the oboe in Costa Rica has been established for only a few decades.

A central challenge is the limited size of the Costa Rican oboe repertoire and the absence …

Beyond Green: Re-Reading "Wicked" As Anthropological Text, Tan Gia Bao Huynh

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

This paper examines "Wicked" through the lens of cultural borderlands, revealing how the musical dramatizes the creation and navigation of social boundaries. By analyzing Elphaba's journey, the research demonstrates how her green skin serves as a powerful metaphor for cultural otherness, while her experiences at Shiz University and beyond illustrate strategies of resistance, accommodation, and identity formation familiar to those navigating between dominant and marginalized spaces. Particularly significant is the paper's examination of Oz's propaganda system, which demonstrates how cultures manufacture monsters and heroes through selective storytelling and public ritual. This analysis offers fresh insights into "Wicked's" enduring appeal, suggesting …

Physical Space And Democratic Citizenship: Third Place Usage And Civic Engagement Among Undergraduates, Justin L. Fintel

Honors Program: Senior Projects (Public)

This thesis examines the relationship between third place usage and civic engagement levels among undergraduate students at the University of Nebraska-Lincoln. Drawing on urban planning and political science literature, I hypothesize that students who more frequently use and interact with campus third places—which are informal communal spaces that foster community, such as coffee shops, libraries, and student unions—demonstrate higher levels of civic engagement. Using survey data from thirty-eight undergraduates and ordinary least squares regression analysis, I find strong support for my hypothesis. Third place usage significantly predicts civic engagement (β = 0.609, p < 0.001) statistically, and this relationship remains robust even after controlling for family socialization and socioeconomic status. The findings suggest that physical spaces on college campuses play an independent role in promoting democratic citizenship beyond students' pre-existing characteristics. These results have important implications for university and urban planning, while highlighting the value of investing in communal campus spaces as mechanisms for promoting civic participation.

The Effect Of Cerebral Somatosensory Network Priming On Language Function In Chronic L-Mca Ischemic Stroke: A Companion Case Study, Mandelin E. Wollesen

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Chronic aphasia following a left middle cerebral artery (L-MCA) stroke is often associated with limited recovery beyond the acute phase, necessitating interventions that target neuroplastic mechanisms. This study examined the effects of somatosensory pneumotactile stimulation paired with cognitive-linguistic tasks on functional language performance in an individual with chronic aphasia. Using a single-subject pre-post design, the participant completed a 10-week intervention protocol involving repeated pneumotactile stimulation via the GALILEO system combined with language and motor tasks. Outcomes were assessed using standardized measures, discourse-based language samples, oral reading, repetition, and phonemic verbal fluency. Discourse was analyzed using Correct Information Units (CIUs), words …

Addressing Legal Uncertainties In Article Versions And Institutional Copyright Policies To Support Immediate Public Access To Federal Grant-Funded Publications, Yuanxiao Xu

Copyright, Fair Use, Scholarly Communication, etc.

New federal public access policies—mandated by the 2022 OSTP Memo and already adopted by several key federal grant-making agencies—require authors funded by federal grants to deposit peer-reviewed publications for immediate public access. This paper explains how grant- receiving institutions and their affiliated authors can dispel legal uncertainties and comply with the new public access policies. Section I delineates how valid prior licenses enable public deposit of manuscripts notwithstanding later publishing agreements transferring copyright to the journals. Section II discusses the different versions of a manuscript created during the publication process. Section III describes the different types of third-party contributions incorporated …

Guidance For Left-Turn Flashing Yellow Arrow (Fya) Implementation In Nebraska, Aemal Khattak, Li Zhao, Frank Selase Dzawu

Nebraska Department of Transportation: Research Reports

This research evaluates the safety performance of flashing yellow arrows (FYA) and driver behavioral responses in Nebraska, using data from 324 FYA intersections (Lincoln 160; Omaha 164) to develop evidence-based implementation guidance. The study addresses critical knowledge gaps in local driver acceptance patterns, the effectiveness of phasing configurations, and a comprehensive safety assessment that integrates crash and conflict analyses. The methodology employed four complementary analyses: (1) negative binomial crash frequency modeling of 3945 unique left turn crashes (2015-2024) across Lincoln and Omaha; (2) binary logistic regression of 948 gap acceptance decisions across 43 intersections; (3) linear regression of post-encroachment time …

Update Of Intersection/Interchange Guidelines For Rural Expressways In Nebraska, Aemal Khattak, Mm Shakiul Haque

Nebraska Department of Transportation: Research Reports

Nebraska Department of Transportation (NDOT) staff frequently decide on changes to existing two-way stop- controlled (TWSC) intersections on rural expressway to alternative facilities, such as a restricted crossing U-turn (RCUT), a roundabout, a signalized intersection, or an interchange. As Nebraska makes progress toward completion of its expressway system, updated and defensible decision-making is essential for conversion of TWSC highway intersections. NDOT’s existing guidelines, developed in the 1990s, no longer reflect current operations, safety performance, or modern intersection designs.

This project updated and expanded NDOT’s guidance using contemporary traffic operational and safety data, combined with robust microsimulation and safety performance modeling. …

Ultra-High-Performance Concrete (Uhpc) For Bridge Deck Overlay And Structural Deck Repair, Jiong Hu, George Morcous, Akbota Aitbayeva, Ming Gerges

Nebraska Department of Transportation: Research Reports

Ultra-high-performance concrete (UHPC) is an advanced cementitious material known for its exceptional strength and durability, making it an ideal material for bridge deck overlays and repairs that address the common issue of premature deck deterioration. Conventional UHPC is typically flowable and self-leveling, which makes it unsuitable for deck surfaces with cross-slopes and/or sloped vertical profiles. Therefore, a highly thixotropic UHPC that responds well to vibration while remaining stable on sloped surfaces is needed for overlay applications. Mixtures with varying binder content, water-to-binder ratio, fiber content, and dosages of admixtures were developed and evaluated. Two of the most effective and economical …

Divided We Stand: Exploring Public Perceptions Of Georgia’S Political System, Luka Lazishvili

Department of Sociology: Dissertations, Theses, and Student Research

Recent years have witnessed increasing concern about democratic backsliding across different regime types, raising important questions about how citizens perceive the legitimacy of political systems during periods of institutional decline. Since 2019, the Republic of Georgia has been experiencing a sustained period of political unrest, which has deepened political polarization and contributed to a decline in Georgia’s Democracy Index. This study examines how citizens perceived the legitimacy of their political system amid democratic backsliding between 2019-2024.

Drawing on legitimacy theory and social identity theory, this study analyzes three waves of cross-sectional data from the Caucasus Barometer survey (2019, 2021, and …

Rhetorical Violence: The Rhetorics Of Women's Counter Political Violence, Kylie Rowland

Department of English: Dissertations, Theses, and Student Research

Protest is omnipresent, and yet not much is known about the efficacy and impacts of its different rhetorical strategies—particularly so for marginalized populations, whose available means of protest are already limited by both material realities and assumptions that govern who and what can make waves. This bind is further exacerbated by gendered and racialized civility politics that determine which bodies can be disruptive and which already are considered “violent.” To address this gap, I turn toward the under-researched rhetorical potentials of marginalized people’s—specifically women and queer folks’—use of symbolic protest “violence,” which works to strategically make evident the larger ongoing …

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 …
