Eschatological Echoes: Reading The Bible And The Harry Potter Series, Athira Mohan Dr

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

Death has been a major topic in children’s and adolescent literature , which has invited scholarly discourse over different ages. While death was very commonly featured in the puritanical texts of the eighteenth and nineteenth centuries, it was also deemed to be a subject too sensitive for the genre of children’s literature in the early twentieth century(Aries 1975), due to a combination of factors such as lowered child mortality rate and heightened concern for childhood as a special social category. However, contemporary children’s and adolescent literature focuses on death as an important part of human life, and invites discussions on …

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

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

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 Role Of Cross-Cultural Connections In Leadership Identity Development: From Entry To Embodiment, Jennifer Okoliko

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

Leadership identity development has received considerable attention in the literature, but most of what we know comes from studies focused on students in formal leadership programs or on the mentee’s side of mentoring relationships. Less understood is the mentor's leadership identity development journey and the role of culture in that process.

This study explores how mentors from low power distance cultural backgrounds who engaged with mentees from high power distance cultural backgrounds interpreted the impact of those experiences on their leadership identity development.

Using Interpretive Phenomenological Analysis (IPA), I conducted two semi-structured interviews with ten participants recruited from different formal …

Social Media Adoption In Urban And Rural Flood Risk Management: Evidence From Nebraska’S 2019 Flood-Affected Regions, Anisha Khandokar

Community and Regional Planning Program: Theses

Flooding is one of the most devastating natural hazards, causing significant economic losses and threatening public safety. While social media has emerged as a powerful tool for disaster communication, its effectiveness in rural flood risk management remains underexplored. This study evaluates the role of social media in disseminating flood-related information and engaging communities during and after 2019 Nebraska floods. This study incorporates SWOT (strengths, weaknesses, opportunities and threats) analysis method to examine how the seven core communication functions were utilized for flood risk management at the state, regional, and local levels. The findings reveal that while state agencies dominated social …

Demographic Trends And Far-Right Party Support In Europe: The Role Of The Cordon Sanitaire, Maxwell Curry

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

This study examines whether cordons sanitaires, institutional exclusionary arrangements common in Western and Central Europe on the part of mainstream political actors aimed to prevent far-right political parties perceived as posing a threat to liberal democratic order from entering into governing coalitions or otherwise participating in mainstream political life, condition the relationship between immigration-related demographic change and support for far-right political parties. Contemporary scholarship has extensively examined the relationship between immigration and support for far-right political parties, but comparatively little research has examined the institutional factors that potentially condition such a relationship. In an analysis of parliamentary election data …

Evaluation Of A Vortex Flow Device On A Center Pivot Irrigation System, Ankit Chandra, Derek M. Heeren, Tyler Smith

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

This study presents the first independent field evaluation of a passive vortex flow device designed to reduce hydraulic friction in pressurized irrigation systems. Experiments were conducted on a full-scale, groundwater-fed center pivot irrigation system at the Eastern Nebraska Research, Extension, and Education Center (ENREEC). A paired comparison approach was used to quantify differences in flow rate, energy consumption, and pressure distribution along the pivot lateral under baseline (no device) and treatment (device installed) conditions. Results showed negligible change in system flow rate (621 vs. 618 gpm) and energy consumption (~1.2% difference), consistent with expectations for pressure-regulated irrigation systems. However, the …

Exploring Gene Regulatory Neural Network Biocomputing Of Bacteria, Adrian Merle Ratwatte

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

Artificial Intelligence (AI) has evolved from brain-inspired algorithms into a discipline that increasingly integrates with biological systems. While silicon-based platforms have advanced machine learning, they remain limited in energy efficiency and operation in environments beyond silicon. This motivates biological computing as an alternative, enabling efficient, resource-aware, and reconfigurable computing within living systems. This dissertation addresses these limitations by introducing a bacterial computing framework that models Gene Regulatory Networks (GRNs) as Gene Regulatory Neural Networks (GRNNs). The GRNN mirrors the structure and function of Artificial Neural Networks (ANNs) through gene-gene interactions across trans-omic layers, enabling natural, self-regulating information processing within living …

Teacher Culturally Sustaining Practices Supported By Generative Ai: Instrument Development, Guy Trainin, Azadeh Hassani, Shuling Yang

Research and Evaluation in Education, Technology, Art, and Design

Generative AI (GenAI) carries the dual potential to reproduce educational inequities and to expand opportunities for multilingual support, critical evaluation, and personalized learning. This paper reports the development and initial validation of an instrument measuring K-12 literacy teachers' perceptions of GenAI's capacity to support culturally sustaining pedagogy. Grounded in culturally sustaining pedagogy (CSP) and its asset-based commitments, the instrument operationalizes three constructs, namely academic success, cultural competence, and critical consciousness, across both teacher and student use. Items were drawn from the CSP literature and refined through cognitive interviews, then administered to 109 PK-12 language arts educators. Reliability was strong for …

Data sources included reflexive journals, semi-structured interviews with former Rotary Youth Exchange students with whom I developed enduring family relationships through hosting experiences, and personal and educational artifacts …

Diagnosis Of Covid-19 Impact On The Construction Employment: Decline And Recovery, Anil Baral, Abdullah Alnuaimi, Yunping Liang, Baabak Ashuri, Mohsen S. Shahandashti

Durham School of Architectural Engineering and Construction: Faculty Publications

The Coronavirus Disease 2019 (COVID-19) had an unprecedented impact on U.S. construction employment. The assessment of employment declines and recoveries across various construction sectors, workforce demographics, and geographic regions helps develop inclusive long-term plans to overcome the setbacks of natural hazards, such as the COVID-19 pandemic. Existing methods for quantifying the employment decline from sudden shocks do not consider trends and seasonality of construction employment under normal conditions. Hence, it is not clear whether the employment declines are due to the impact of a disaster or associated with trends and seasonal patterns of employment. The objective of this research is …

By the means of eco-critical approach in the name of Vi-kas (development) Banerjee discuss the acts of slow violence subverted on nature in the name of progress (vikas). Through text/ images the author depicts chaos and challenges for the readers in more direct and obscene ways. The current paper attempts to look at Banerjee’s illustrations and images as new form of language emerged in modern Indian literature with the possibly that illustrations have more effect on …

Shared Language For Responsible Ai Integration, Asa B. Stone, Mark C. Stone, Alisha Bevins, Jean Claude Niyomugabo, Irene Magara, Jacob Abaare, Derek M. Heeren, Mubarak Abu Zouriq

PRAIRIE: Pioneering Responsible AI for Research, Innovation, and Education

As AI rapidly reshapes how we work and learn, employers increasingly seek graduates who can think before they prompt, exercising judgment under pressure rather than merely producing output. Yet students are praised for AI use in one course and penalized for it in the next, and faculty are left to lead responsibly on shifting ground, with no shared language to guide them.

This paper introduces the PRAIRIE Framework for AI Integration, a shift from reactive gatekeeping toward proactive stewardship. It emerged from a qualitative sentiment analysis of three communities (students, faculty, and industry partners) whose concerns converged on one need: …

Investigation Of Warfarin–Human Serum Albumin Binding By Ultrafast Affinity Extraction Using Single- And Dual-Column Affinity Microcolumn Systems, Samiul Alim

Department of Chemistry: Dissertations, Theses, and Student Research

This dissertation examined the interaction of warfarin with human serum albumin (HSA) by using affinity chromatography, with particular emphasis on ultrafast affinity extraction (UAE) and affinity microcolumns. HSA affinity supports were prepared by immobilizing HSA onto diol-bonded silica via Schiff base chemistry and used to prepare affinity microcolumns for chromatographic studies under physiological-like conditions at pH 7.4 and 37.0 °C. UAE studies were performed to investigate the effects of residence time, flow rate, and column configuration on the measured apparent free fraction of warfarin and on the calculated apparent binding parameters. The results showed that the measured apparent free fraction …

Gobbling Activity And Use Of Structural Habitat At Nest Sites By Wild Turkeys (Meleagris Gallopavo) In Western Nebraska, Robyn M. Dausener

School of Natural Resources: Dissertations, Theses, and Student Research

Wild turkey (Meleagris gallopavo) populations in Nebraska have declined substantially in recent years. Understanding gobbling chronology and its environmental drivers may inform spring hunting season structure and management actions. I used autonomous recording units (ARUs) in two ecologically distinct regions of Nebraska, the northwestern (NW) Pine Ridge landscape, and the southwestern (SW) agricultural landscape, to quantify gobbling activity from 2023-2025. I paired gobbling data with nesting chronology, cumulative daily hunting pressure, weather conditions, and moon phase using Bayesian generalized additive mixed models. Gobbling peaked during mid-to-late April in both regions, preceding peak nest initiation and incubation, with no …

Hope, Incorporated: Welborn Hope As B.A. Botkin's "Promising" Oklahoma Poet, Cullen Whisenhunt

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

In 1927, a letter by then-professor at the University of Oklahoma, Roy Temple House, was published in the Ada Evening News complimenting Ada, OK, poet Welborn Hope and suggesting Hope get in touch with folklorist and literary scholar BA Botkin, also an OU faculty member. That same year, Botkin published “Oklahoma Poets, Inc.,” in which he detailed what he believed to be the three stages of a state’s literary development: the pioneer stage, the popular rhymesters stage, and finally, the union of art and life (30-31). In 1935, Botkin presented a lecture in Tulsa in which he cited Hope among …

Recognition Of The Spring Flight Of Celastrina (Tutt) (Lycaenidae: Polyommatinae) In Southern New England As An Introgressed Hybrid Species, Harry Pavulaan

The Taxonomic Report of the International Lepidoptera Survey

Populations of Celastrina (“Azure”) butterflies in southern New England have historically been referred to as either C. ladon (Cramer) or C. lucia (W. Kirby) by various authors. Following the discovery of elongated dorsal wing scales in males of C. ladon (D. Wright & Pavulaan, 1999; Ômura et al., 2015)—structures that replace the androconia that are typically present in most Celastrina species—it was believed that this trait was restricted to C. ladon, C. nigra (W. Forbes), and, more recently, C. iryna (Pavulaan, 2025). Microscopic examination of male “Spring Azure” specimens from across southern New …

Interparental Relationship Quality Reduces Parental Stress And Subsequent Family Dysfunction Across Pregnancy And Early Childhood, Rachel Clara-Beth Beck

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

In this multiple paper dissertation, I found that a higher quality interparental relationship, characterized by more emotional intimacy, support, responsiveness and better conflict management skills, plays a key role in reducing stress and its subsequent impact on family dynamics. Aims and hypotheses were tested using longitudinal data collected from mixed-sex couples during the pregnancy-postpartum transition and into early childhood. In study #1, higher quality interparental support during pregnancy was associated with lower postpartum stress which, in turn, predicted fewer parent–infant bonding impairments. In study #2, a mutually responsive orientation in the couple relationship during pregnancy interacted with intrapersonal regulatory resources …

Online Legislation: Developments And Trends In Data Privacy And Software Development, Garrett J. Splinter

Honors Program: Senior Projects (Public)

The increasingly relevant interaction between the law and data privacy, as well as compliance requirements enforced by the United States, is currently in a state of transition. Various states, such as California, Colorado, Connecticut, Nebraska, and many others, all have passed legislation with varied requirements and definitions that make for a challenging framework in which software developers operate, as the universal nature of the internet renders their compliance with current legislation a challenge. Enforcement also tends to be relatively relaxed in most modern examples, though it has escalated after 2020, and this trend may continue in the future, lending credence …

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 …
