Brazilian Souls: Portraits Of Brazilian Nationalism In The Piano, Rafael Lima Lima De Paula

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

This portfolio consists of the artifacts of the creative, artistic and research work realized during my doctoral studies. In its core, all recitals had Brazilian music, especially that of H. Villa-Lobos, as a unifying element, although personal taste and reasoning were also a driving force behind choosing repertoire and building a theme for each recital. The research work is connected to the repertoire performed, with Villa-Lobos' music and the Brazilian nationalist movement as common threads. “Respectful Majesty,” the research paper attached to Recital 1 analyzes elements present in Villa-Lobos Bachianas Brasileiras N.4 and brings the piece's neoclassical nature to the …

Lightweight Attestation Techniques For The Industrial Internet Of Things, Syed Owais Athar

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

The Industrial Internet of Things (IIoT) has transformed critical infrastructure by integrating programmable logic controllers (PLCs) with connected sensors, actuators, and supervisory systems. While these advancements enhance operational efficiency, they also increase exposure to sophisticated cyber-physical threats, particularly through malicious modifications of PLC programs. Existing attestation methods either impose significant computational burdens by performing continuous verification or rely on detailed physical models that are often impractical to maintain across heterogeneous environments.

The first part of this thesis focuses on DuAtt, a dual-layer attestation scheme that integrates a physical process–based anomaly detection mechanism with a targeted attestation of the PLC program. …

The Value Of Difficulty In Engineering Education To Professional Work Experience Of Early Career Engineers: A Multiple Case Study, Nosakhare Iyobosa Idiaghe

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

Engineering education has long been characterized by rigor, intensity, and selective sorting, conditions often justified as necessary for producing capable engineers. Yet, despite the widespread assumption that academic hardship prepares students for professional practice, relatively little empirical work has examined how graduates themselves interpret the value of these difficult experiences once they enter the workforce. This dissertation addresses that gap by investigating how early-career engineers make sense of the difficulty encountered in their undergraduate education and how those experiences compare to the challenges of engineering practice.

Using a qualitative multiple‑case study design, the research draws on semi‑structured interviews with eight …

Leading While Black: An Examination Of The Black Supervisor Experience Overseeing White Subordinates In Higher Education, Colette Marie Tobias

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

This study examines how systemic racism and social capital hierarchies shape the supervisory experiences of Black supervisors. While existing literature has explored leadership and race, it has not fully examined how systemic racism shape Black supervisors’ experiences or how social capital hierarchies play into the behavioral responses of white subordinates. This study addresses that gap by centering the lived experiences of Black supervisors within higher education.

Grounded in narrative inquiry, this research focuses on how participants make meaning of their experiences through their stories. Data was collected through semi-structured interviews and reflective journals with 19 Black supervisors who had at …

Examining Associations Between Cognitive Factors And Behavior To Promote Culturally Responsive Teaching In Middle School Math: A Conceptual Replication Study, Ashley Struebing

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

The purpose of this research was to examine the association of middle school math teachers’ cognitive processes on their use of culturally responsive teaching (CRT) practices to promote CRT in middle school math classrooms. Specifically, a quantitative, cross-sectional research design was used to conduct a conceptual replication of Comstock et al. (2023), and to extend their research by exploring the association between teachers’ self-efficacy in teaching math and their use of CRT practices. Participants in the current study were urban and rural middle school math teachers who may or may not have been involved in a CRT professional development program, …

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

This document presents a series of analytical program notes for six orchestral and chamber works spanning four centuries, examined through the intersecting lenses of conductor and educator. The works under consideration, Veracini's Concerto for Violin in D Major, Schubert's Overture to Rosamunde D. 644, Brahms' Serenade No. 2 in A Major Op. 16, Elgar's String Serenade in E Minor Op. 20, Piston's Divertimento for Nine Instruments, and the author's own Tresillos for Orchestra, are treated not merely as historical objects but as active performance problems whose solutions require the integration of scholarly analysis, historically informed practice, and …

A Pedagogy Of Connection: Potentials And Practices For The English Classroom, Alexandra Bissell

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

In a moment characterized by rapid technological advancement and sociopolitical volatility, the academy currently faces the need to redefine what a college education can offer students and reimagine how it delivers on that promise. This dissertation proposes a pedagogy centered on the process of connection as one way that English educators at the collegiate level might approach our teaching and respond to this call. Connection is relational, but also textual and conceptual, and I contend that establishing connection as the catalyst for our pedagogical practices is a powerful way to move forward and support our students’ intellectual growth as well …

Hormesis In Plants: Implications For Weed Management And Crop Production, Luka Milosevic

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

Hormesis is a biphasic toxicological phenomenon in which low doses of a stressor stimulate biological performance of an organism, while higher doses inhibit it. In plants, hormesis has been documented following exposure to various environmental stressors, including herbicides, pollutants, and thermal stress. However, the physiological basis of hormesis and its implications for crop production and weed management remain poorly understood. Thus, the objective of this dissertation was to investigate hormetic responses in plants and evaluate their agronomic significance for crops and weeds using representative model species. A combination of field and controlled-environment experiments was conducted to quantify plant responses to …

Investigating Book Challenges: Reasons For Challenges, Changes In Public Opinion, And Removals In U.S. School Districts, Makena Nail

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

The American Library Association documented an increase in book challenges in the U.S. in recent years. These are attempts to censor or limit access to books on library and book store shelves and are mostly brought by organizations and elected officials. There is much more research on which particular books are challenged and the reasons for the challenges than on general public opinion about the need for limiting access to books (PBS, 2022; American Library Association, n.d.). Previous research demonstrates that when books are challenged, the underlying goal is protecting community values by limiting access to ideas that some believe …

Dividing To Survive, Fight, Or Ally: Understanding Terrorist Group Splintering, Makayla Wendland

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

The splintering of terrorist groups is extremely common, with members breaking from the ranks of an existing organization to establish a new, independent organization. At times, the process of splintering has produced some of the deadliest terrorist groups globally, significantly affecting the trajectory and intensity of conflict. Conversely, there are times when splintering can produce groups that quickly dissipate without having an impact. This variation in lethality frames the question at the center of this dissertation: how do splinter groups behave and operate in their conflict landscape?

I develop a new theory-based typology to explain variations in the behavior and …

Perception Of 3d Data Visualizations, Tyler Wiederich

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

Data visualizations are powerful tools for communicating complex data structures. They are typically presented in 2-dimensional formats, such as on paper or computer screens. In recent years, technological advancements have enabled traditional data visualizations to be fully rendered in physical environments through 3D printing, offering more natural interactions. However, this style of graphical rendering remains largely unexplored in empirical evaluations with traditional charts. In this research, we conducted two experiments to assess ratio estimations across 2D and 3D charts in digital and physical environments. The first study partially replicated Cleveland and McGill’s (1984) work in perceptual tasks and expanded to …

Developing Best Recommendations For Aerial Application And Chemigation Of Insecticides For Western Bean Cutworm (Striacosta Albicosta Smith) Management In Corn, Andrea Rilakovic

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

Western bean cutworm, Striacosta albicosta (Smith), is a univoltine moth in North America, recognized as an economic threat to both corn (Zea mays L.) and dry bean (Phaseolus vulgaris L.). In the Midwest of the United States, S. albicosta can cause severe damage by reducing the quantity and quality of corn ears through larval feeding. Currently, options for Bacillus thuringiensis (Bt) proteins that can effectively control S. albicosta are limited, relying on only one Vip3A effective protein, while other growers use insecticide application via airplanes or center pivot irrigation systems, known as chemigation. Given the importance …

A New Subspecies Of Papilio Indra (Papilionidae) From The West Desert Of Utah, Usa, Wayne H. Whaley, Alexander A. Jason, Todd L. Stout

The Taxonomic Report of the International Lepidoptera Survey

Papilio indra bonnevillensis is a new described subspecies partly based on taxonomic rearrangement of its larval host plant reproductive phenology relative to Wasatch Range nominate P. indra. It is geographically isolated in Utah’s West Desert from populations of ssp. nevadensis to the west and ssp. calcicola to the south. In addition to phenological differences compared to these two subspecies, it merits description based on host Lomatium depauperatum which recently speciated from L. grayi, neither of which is used as host by other subspecies of P. indra. The evolution of new host L. depauperatum is …

The Intersection Between Adolescent Pregnancy, Mental Health Concerns, Stigma, And Sex Education, Madelon Cox

Honors Program: Senior Projects (Public)

This thesis discusses research from the past two decades focused on factors contributing to an increased risk of adolescent pregnancy and the lasting impact of that pregnancy. The consequences of being a pregnant adolescent can be compounded by race, gender, socioeconomic class, and access to education. Adolescent pregnancy also carries significant physical and mental health risk for the adolescent and the child. Awareness and various interventions can help pregnant adolescents or those who may be at risk for adolescent pregnancy to support them, prevent isolation, and reduce further negative mental health conditions, such as depression and anxiety.

Substance Use And Childhood Environment In Adolescent Head Injury: Examining The Effects Of Race, Jessica A. Phelps

Department of Sociology: Dissertations, Theses, and Student Research

Adolescents participating in sports are at an increased risk of concussion, which is particularly important given the difficulties with cognitive function, emotion regulation, and impulsivity that may occur as a result of this brain injury. These symptoms can predispose adolescents to subsequent concussions, leading to further damage during a critical time in neurodevelopment which can result in mental health disorder development in adulthood. It is crucial to understand what factors may predispose youth to increased rates of concussion for these reasons. As such, this paper explored whether race/ethnicity, gender, grade in school, childhood environment, and risk-taking behaviors were associated with …

Social Bonds And Dynamic Risk In Predicting Juvenile Recidivism Among Florida Probation Youth, Shadrach Sackey

Department of Sociology: Dissertations, Theses, and Student Research

Juvenile recidivism remains a persistent challenge within the United States juvenile justice system, particularly among youth supervised in community-based probation programs. This study examines how family context, school engagement, peer associations, antisocial beliefs, and overall dynamic risk are associated with recidivism among juvenile probation youth in Florida. Drawing on social bond theory and social learning theory, the analysis uses administrative data from the Florida Department of Juvenile Justice (FDJJ) Juvenile Justice Information System, including 6,215 youth who completed community-based probation supervision between 2015 and 2018. Recidivism was measured using two outcomes within a 365-day follow-up period: rearrest and readjudication. Descriptive …

Evaluating The Impact Of Intercropping Vegetables And Cut Flowers On Yield And Conservation Biological Control, Alliance Igiraneza

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

Specialty crops such as vegetables are some of the most susceptible to yield losses and increased management difficulty over time due to pests. One of the potential solutions to this problem, which aims at ensuring the sustainability of the sector, is using conservation biological control practices such as intercropping to increase diversity, while maintaining the economic feasibility and profitability of the system. This study was conducted to evaluate the impact of this management practice using Bell pepper (Capsicum annuum var. King Arthur) as the main crop, intercropped with flowers including zinnia (Zinnia elegans var. Benary’s Giant), sunflower ( …

Understanding Challenges Faced By Refugee Women And Women With Experiences Of Forced Migration In Entrepreneurship In The Midwest Region Of The United States, Ritu Jadwani

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

The labor market participation of refugee women was only 6%. The United States had the maximum employment rate for the refugee women population, which was 40%, as compared to 6% in Germany, Lebanon, and Jordan (Kabir & Klugman, 2019). Refugee women faced many challenges in labor force participation and especially in entrepreneurship. As demonstrated by Desai, Naude, and Stel (2020), refugees faced challenges like cultural integration, language barriers, level of education, and acceptance of education merits. This eventually led to disparities in income generation. Thus, many either remained in low-paying jobs or started their own business (Desai et al., 2020). …

The Goad, The Bad, & The Ugly: The Livestreamed Vice Signaling & Body Fascism Of Clavicular & Asmongold, Jacob T. Fry

Department of Communication Studies: Dissertations, Theses, and Student Research

This thesis explores the rhetorical, material, and symbolic implications of fascist livestreaming in the United States through two popular streamers: Clavicular and Asmongold. These two streamers represent a small slice of the rise of different reactionary rhetorics online and how the use of different masculine subcultures—in this case ‘Looksmaxxing’ or Gamer inspired rhetoric—are used as ideological texts for white male supremacy. Whether in front of the glow of their gaming monitor or the flashing lights of a nightclub, the livestreaming of the body, home, relationships, and lifestyles challenge rhetorical conceptions of style, the ‘public/private sphere,’ and political communication. As different …

Beyond The Cycle: How Menstruation Influences Gender Identity And Well-Being In Binary And Non-Binary Adults, Rin Nguyen

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

Approximately 1.8 billion people worldwide menstruate, including transgender and gender-diverse (TGD) people, yet their experiences remain underrepresented in research. Given that menstruation can affect gender alignment and psychological well-being, understanding its impact on TGD people is critical. Gender congruence, or alignment between one’s gender identity and expression, is a key factor influencing well-being, with research linking it to reduced depression and anxiety. Furthermore, emerging research on gender euphoria, the joy experienced when gender congruence is experienced, suggests it may serve as a protective factor for mental health and well-being. Gender euphoria has been associated with reduced psychological distress and increased …

The Impact Of Community On Professional Identity In Computer Science Education, Ian A. Kollipara

School of Computing: Dissertations, Theses, and Student Research

This thesis explores the application of Communities of Practice (CoPs) in Computer Science Education. The work consists of two qualitative studies examining related but distinct populations: (1) K–12 CS teachers and (2) undergraduate CS students. The first study presents a retrospective analysis of conneCTION, an online CoP for K–12 CS educators, identifying strengths, weaknesses, and design considerations that inform future platform development. The second study investigates how participation in a CoP can mitigate negative and exclusionary stereotypes in CS. This study was conducted in an under-explored context: a small, private, religious, Midwestern university, and examines an existing community, the Programming …

Carcass Mass And Cooling Dynamics As Determinants Of Beef Color, Tenderness, And Dark-Cutting Risk, Grace C. Johnson

Department of Animal Science: Dissertations, Theses, and Student Research

Discoloration in beef has important implications to the beef industry. Dark-cutting (DC) beef remains one of the most economically significant color defects; however, industry prevalence has only marginally declined (≈ 0.1%) despite mitigation efforts. This lack of improvement largely stems from research focused on pre-harvest stress and glycogen depletion leading to dark, firm, and dry (DFD) beef. However, not all darkcutting beef originates from DFD phenotypes. Atypical dark-cutting (ATDC) phenotypes have recently been observed and do not exhibit the classic metabolic indicators of DFD. This trend coincides with steadily increasing carcass weights in the beef industry and raises the possibility …

Measuring Urban Space: A Spatial Framework For Transit Stop Siting, Michael R. Leiting

Architecture Masters of Science Program: Theses

Urban investment projects, particularly those related to transit infrastructure, are often evaluated through quantitative metrics that emphasize economic output, proximity, and development potential. While these measures provide useful benchmarks, they offer limited insight into the spatial conditions that shape how environments are structured, navigated, and occupied at the human scale. As a result, sites that appear comparable through conventional metrics may produce fundamentally different spatial experiences.

This thesis develops a drawing-based framework for evaluating spatial conditions across multiple urban sites. Four primary conditions, Urban Form, Threshold, Mobility, and Public Realm, are analyzed through standardized drawings and translated into corresponding indices. …

After Antiquity: Between Preservation And Disappearance, Elizabeth Pernicek

Architecture Masters of Science Program: Theses

This thesis investigates how architectural remnants evolve from sacred or civic monuments into global spectacles and how these transformations reveal the relationship between architecture, power (be it political or otherwise), and cultural memory and significance. Through studying cycles of sacredness, destruction, and spectacle, this thesis explores architecture’s role as a living record of cultural transformation.

This thesis proposes that architectural remnants do not passively exist after their moment of rupture, but are actively shaped through systems of preservation, authority, and cultural framing. While remnants appear to operate as historical artifacts, they are in fact continuously rewritten through intervention, restoration, and …

From Prairie To Practice: Forensic Taphonomy, Ethics, And Regional Ecology In Southeastern Nebraska, Jessica F. L. Gammage

Department of Anthropology: Theses and Student Research

Forensic taphonomy examines the postmortem processes that affect human remains within specific environmental contexts and plays a critical role in medicolegal death investigation. Despite significant advances in decomposition research, experimental studies remain geographically and environmentally uneven, limiting the transferability of postmortem interval (PMI) estimation methods across regions. The Central Great Plains are underrepresented in forensic taphonomic research despite its distinct ecological and geomorphological characteristics.

This thesis evaluates southeastern Nebraska as a specific regional setting for forensic taphonomic research by integrating ecological, pedological, and geomorphological data with current forensic literature. Tallgrass prairie vegetation, loess-derived soils, seasonal moisture variability, and dynamic fluvial …

Understanding Roma Oppression In Europe Through Humantarian Forensic Analysis, Christal L. Quinn

Department of Anthropology: Theses and Student Research

This thesis examines the marginalization of Roma people in Europe, and how humanitarian forensic practices may help Roma communities in their quest for justice and recognition. The study draws exclusively on secondary information to examine the social, political, and legal issues affecting the Roma communities, who have endured centuries of institutional discrimination, marginalization, and violence. This thesis identifies ways in which systematic oppression continues to limit Roma communities’ access to education, housing, healthcare, and legal protection through a review of relevant literature and applicable theoretical frameworks. The study also examines the relevance of forensic science, particularly its humanitarian applications, in …

Rehumanizing Anatomized Individuals: Using Osteobiographies As A Step Towards Reparative Justice, Lillie C. Turpin

Department of Anthropology: Theses and Student Research

In 1985, India banned the export of human remains. This ended the major trade route for primarily US and European anatomical supply companies. Until this point, companies like Carolina Biological Supply exploited and erased vulnerable people's identities, molding them into anonymous anatomical specimens. This study investigates the life and postmortem history of twenty-five individuals, previously used as anatomical specimens, housed at the University of Nebraska–Lincoln. Using an osteobiographical approach, this research reconstructs aspects of these individuals' lived experiences and examines how anatomical preparation practices reflect structural violence and apathy.

Skeletal analysis of twenty-five individuals revealed a range of biological profiles, …

A New Electroencephalography Electrode Design For Curly And Kinky Hair Types, Elena Butler

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Medical discrimination and implicit bias are present in both societal systems and into the design and validation of medical devices. Traditional electroencephalography (EEG) systems often fail to provide reliable physiological recordings on curly and kinky hair types (3B–4C), associated typically with Black American and others of African descent. EEG on these hair types often results in high electrode-scalp impedance, poor signal quality, and participant discomfort. Consequently, such technical biases contribute to the underrepresentation of these populations in neuroscience research and clinical diagnostics, while simultaneously limiting equitable access to EEG-based medical care.

To address this gap, a novel conductive electrode attachment …
