Extending The Geometric Phase To Relativistic Spacetime, Sajid Raihan Akash

Department of Physics and Astronomy: Dissertations, Theses, and Student Research

The Berry phase [3] is traditionally understood as a geometric phase acquired during cyclic adiabatic evolution, often interpreted as the flux of an effective “magnetic field” through a solid angle in parameter space. In this thesis, we investigate situations in which a geometric phase arises even when no spatial solid angle is enclosed, revealing the limitations of the standard purely spatial interpretation. We first review the Berry phase for a spin-½ particle in a slowly varying magnetic field and analyze scenarios in which the system’s eigenstate is changed during the adiabatic evolution. We show that the resulting phase can be …

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 …

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 …

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 …

Parent-Child Interactions Across Contexts And Children’S Adaptive Classroom Behaviors In Second Grade, Hannah Dalton

Honors Program: Senior Projects (Public)

Adaptive classroom behaviors are important for children’s success in the classroom by supporting their abilities to learn academic concepts and positively engage with peers. Research indicates that parents’ behaviors during interactions with their children are important for their social and academic outcomes, but there may be variance in parents’ behaviors based on their goals for the interaction. The current study examined interaction quality across three parent-child interaction tasks and correlations with their second-grade children’s adaptive classroom behaviors. The sample included 170 second-grade children and their parents who completed three joint tasks: a puzzle task, a homework task, and a conflict …

“No Ifs, Ands, Or Butts”: Analyzing Race And Gender In Sex And The City Through Black Feminist Theory, Daniella Orias

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

This article analyzes Season 3, Episode 5 of Sex and the City, “No Ifs, Ands, or Butts,” through the lens of Black feminist theory. It investigates how race and gender are constructed, stereotyped, and selectively represented within the episode’s narrative. The analysis focuses on two Black characters who were featured only in one episode of the series, Adeena and Chivon, and examines how the show portrays harmful stereotypes such as the angry Black woman (Adeena) and sexualized Black male (Chivon) in the episode. These limited and harmful representations are further scrutinized by the fact that the show is often …

Practical Considerations For Conducting Canine Behavioral Science, Lucrezia Lonardo, Madeline H. Pelgrim, Jeffrey R. Stevens

Jeffrey Stevens Publications

Research on behavior in domestic dogs (Canis familiaris) has increased rapidly recently due to the interest in them as pets, working dogs, and model species for understanding evolution, domestication, and even human health. This interest in canine behavioral science has resulted in the creation of dozens of dog lab worldwide, with more starting every year. Our aim here is to review practical issues that potential dog researchers might consider when deciding how to set up a dog lab and conduct research in canine behavioral science. We hope that this can offer a path forward in promoting high-quality, cutting-edge …

When We Don’T Get Community Right In Restorative Justice Spaces: Cancel Culture And Failure To Transform, Aparna Polavarapu

Nebraska Law Review

This Article argues that community is a central but deeply misunderstood feature of restorative justice. Restorative justice asks us to understand harm as a break in relationship that creates obligations for the person harmed, the person who caused harm, and the community. Community is theorized to play a key role in working towards reintegration and social change, both goals of restorative justice. Yet in practice, community is often misused or underused in ways that weaken these goals. Practitioners are observing an increase in cancel culture actions by groups that claim affinity with restorative and transformative justice. However, by weaponizing the …

Unsettling The West: Migration Routes And Homesteading Through Oral Histories, Sidney Wickham

Nebraska Anthropologist

Westward expansion in the nineteenth-century United States has long been framed through settler-centered historical narratives that emphasize progress and national development. This article employs oral history as an ethnographic method to examine migration routes and homesteading experiences in Nebraska and the broader Midwest, foregrounding how memory, storytelling, and lived experience function as cultural practices. Drawing on interviews with descendants of homesteaders, community members, and museum professionals, alongside diaries, newspapers, and archival materials, this study analyzes how migration was remembered, narrated, and transmitted across generations. Rather than treating overland trails and homesteads as singular pathways of movement, this research situates them …

A Semiotic Analysis Of German-American Cultural Suppression In The Lincoln Freie Presse From 1914 To 1918, Elle Ward

Nebraska Anthropologist

This study performs a historical semiotic content analysis of the Lincoln Freie Presse to document the processes of cultural coercion and resultant identity erasure within the German- American press of Nebraska during the critical period of January 1914 to December 1918. The research establishes a semiotic baseline (1914–1916) characterized by high linguistic and content autonomy and then tracks the immediate, stark shifts following the U.S. entry into World War I (the coercion period) and the succeeding mass anti-German hysteria (1917–1918). Quantitative findings convey a rapid and overwhelming visual conquest of the newspaper’s spatio-textual landscape: patriotic symbolism surged from zero to …

Out-Group And In-Group Relational Trust In Group Coaching With First-Grade Teachers: A Single Case Study, Jentry S. Barrett, Rachel E. Schachter, Jungwon Eum, Gwen Nugent, Kathleen M. Rudasill

Department of Child, Youth, and Family Studies: Faculty Publications

Coaching has become a prominent professional learning tool for helping early childhood teachers (birth–8) implement curriculum and research-based practices in their classrooms. One coaching strategy that supports positive changes in teacher practice and child outcomes is building trust between the coach and teacher(s). However, there is limited understanding of the nature of trust-building in coaching, particularly in group coaching configurations. There are two types of trust to consider in the context of group coaching: out-group trust between an outside coach and the teachers, and in-group trust between the teachers experiencing coaching who already have a relationship. This case study aimed …
