Testing Effects Of Acoustic Propagation, Morphology, And Intrasexual Selection On The Elaboration And Performance Of Song In Bachman’S Sparrows (Peucaea Aestivalis), Hans Kayser Gonzembach

Electronic Theses and Dissertations 2020 - Present

Birdsong is a communication signal shaped by ecological, morphological, and cultural processes. While many songbird species produce relatively simple vocal repertoires, others, such as the Bachman’s Sparrow (Peucaea aestivalis), produce moderately large repertoires with multiple distinct and context-dependent song categories. Despite this complexity, little is known about the major drivers that shape song elaboration in this species. Additionally, it is unclear whether abiotic factors play a significant role in determining how different song types are learned and shared within a population. To better understand how ecological and social pressures shape song variation, I conducted three studies using Bachman’s …

Does Culture Translate? A Case Study On Artificial Intelligencegenerated Text Concerning Japanese-Style Employment, Kanji Kitamura

Languages, Literatures, and Cultures Faculty Publications

Translation matters to international business when it has a discernible impact on firm performance or critical business processes. Current developments include machine translation, which is evolving in tandem with generative artificial intelligence (AI). On one hand, useful translation apps have become available to help the public communicate internationally. On the other hand, recent research concludes that even machine translation's best output still requires post-editing by a human. This argument implies that a machine-translated, grammatically accurate text may not always make sense to a human audience, possibly because of a semantic-pragmatic issue beyond the lexical level. This paper regards it as …

Impact Of Collodion Thickness On Fission Track Generation Within Lexan Employed For Nuclear Forensic Analyses, Ryan K. Chapman, Zachary P. Meisel, Abigail A. Bickley

Faculty Publications

We report results from a computational study of fission track damage within a Lexan substrate caused by ²³⁵U suspended within a collodion film of varied thickness. MCNP6.3 was used to model energy deposition and displacements per atom within a Lexan film coated by a film of collodion, located within the air-filled 6 inch dry tube of a TRIGA reactor. The collodion layer was varied between 20 and 100 μm thickness, resulting in an 8.8% difference in energy deposition and 12% difference in displacements-per-atom within the Lexan substrate. These findings indicate that collodion adhesive thickness has a moderate impact on …

Living To Die: Life Imprisonment Without Remission Or Parole In India, Preeti Pratishruti Dash, Rushil Batra

Articles

This article critically examines the Supreme Court of India’s use of life imprisonment without the possibility of remission or parole (LWORP) as a sentencing alternative to the death penalty. While the Constitution Bench in V Sriharan vs Union of India (2015) upheld the constitutionality of such sentences, it did not articulate principled standards governing their imposition. This article argues that the absence of such standards has produced a vacuum in LWORP sentencing. To substantiate this claim, we analyse fifty-three Supreme Court judgments delivered between 2016 and 2024 in which death sentences were commuted to LWORP. The analysis reveals widespread inconsistency …

"I Wasn't Broken": Addressing Stigma Associated With Dementia While Walking The Talk For Dementia, Kate Irving, Fernando Aguzzoli Peres, Walter D. Dawson, Jonathan Adrián Zegarra-Valdivia, Lingani Mbakile-Mahlanza, Sherril B. Gelmon

Institute on Aging Publications

INTRODUCTION:Walking the Talk for Dementia (WTD) convenes people from every continent and multiple perspectives, including people with lived experience, in a 40- km walk followed by a 2-day symposium. The aim is collective reflective dialogue about dementia stigma without the burden of professional hierarchies.

METHODS: Qualitative reflections during and immediately following the walk were analyzed using content analysis to identify common themes.

RESULTS: Three themes demonstrate an evolution of perspectives about dementia and stigma: “meeting the person not the label”, “a community in solidarity”, and “I wasn’t treated like I was broken, and I wasn’t broken.”

DISCUSSION: WTD created an …

Physical Therapy Assessment Of Work Capacity Gaps In Transition-Aged Youth With Intellectual And Developmental Disabilities, Katelyn Malick, Delaney Roberts, Rachel Ray, Marla Smith, Rhonda Haitz, Anne Woodruff Jameson

Posters and Presentations: Physical Therapy

Individuals with intellectual and developmental disabilities (IDDs) experience disproportionately low employment rates despite expressing a strong desire for community integrated employment. This study examined whether discrepancies exist between the current work capacity of adolescents and young adults with IDDs and the physical exertion demands of their desired careers, and explored the role of physical therapy (PT) in addressing these gaps. Forty-five participants (ages 14–24) in the Nebraska EmployABILITY project identified their top career choice. PT‑assessed current work capacity was compared to the physical exertion requirements of the selected job using a standardized exertion scale. Differences were analyzed using the Wilcoxon …

Historians At War: A Comparative Analysis Between Thucydides And Xenophon's Accounts Of The Peloponnesian War, Juleeanna S. Fuller

Caroliniana Undergraduate Research Journal

This essay analyzes Thucydides and Xenophon's accounts of the Peloponnesian War, reflecting on the intersection of historical narratives, personal bias, and political perspectives. Thucydides’ History of the Peloponnesian War presents Athens’ decline through the lens of moral and political collapse, emphasizing human nature, rationalism, and realism. Despite his reputation for objectivity, his reconstruction of speeches and selective focus revealed an underlying critique of Athenian democracy, shaped by his own life experiences. However, Xenophon's Hellenica continues the narrative with a pronounced Spartan bias, depicting Spartan hegemony and the Thirty Tyrants in a largely favorable or justified light, while minimizing their brutality …

Exploring Decision-Making In Caenorhabditis Elegans: Navigating Dichotomous Envrionmental Cues, Hunarmeet K. Gill

Caroliniana Undergraduate Research Journal

All living organisms thrive off the survival choices they make and the factors they prioritize, but the mechanisms guiding these choices remain unclear. This study investigates decision-making in Caenorhabditis elegans, aiming to understand how they navigate dichotomous environments that contain both attractive and aversive cues. Despite possessing a simple nervous system, C. elegans express behaviors indicating a level of advanced sensory-processing abilities, making them ideal models for studying decision-making processes. The experiment consisted of five separate petri-dish tests, each with three sections: side A and side B (containing natural or UV light and/or E.coli or ethanol), and a neutral …

Comparing The Effect Of Varying Concentrations Of Polytetrafluoroethylene On The Length And Fresh Weight Of Salvinia Minima, Talha Islam

Caroliniana Undergraduate Research Journal

The increasing usage of fluoropolymer pollution in aquatic environments has increased concerns about the ecological consequences of materials such as polytetrafluoroethylene (PTFE), commonly known as Teflon. In the past decade, the usage of Teflon in American homes across the United States has risen by 37.7%, resulting in large amounts of aquatic pollution due to improper disposal of these harmful substances (Török et al., 2020). Although PTFE is chemically inert, its accumulation in freshwater systems can introduce matter that physically interacts with aquatic organisms. This study examined how varying concentrations of PTFE suspensions affect the growth of Salvinia minima, a …

A Dynamic Systems Framework For Customer Lifecycle Management: From Latent State Discovery To Robust Control Policy, Ali Nasirzonouzi

Northeast Journal of Complex Systems (NEJCS)

Traditional marketing often relies on static strategies that fail to capture dynamic customer behavior. This paper introduces an integrated framework to model and control the customer lifecycle, bridging the gap between empirical data and computational simulation. Using the Customer Personality Analysis dataset, we implemented a five-stage methodology. We first identified three distinct customer segments (At-Risk, Standard, High-Value) using Gaussian Mixture Models. To address the lack of longitudinal data, we calibrated a normative transition model based on customer inertia principles. Our analysis revealed that marketing effectiveness is highly state-dependent; notably, At-Risk customers exhibited a 33.5% lift when targeted with catalogs. Leveraging …

Defining The Meta-Story Of Heroism Science: Initiation, Formation, And Governance In An Emerging Discipline, Peter Bray

Heroism Science

This article traces the meta-story of the journal Heroism Science across Volumes 1–10 by treating the publication record as a living narrative of field formation. Using an eight-dimension decoding framework (D1–D8), it argues that the journal’s development is best understood as a braided trajectory in which methodological maturation and theoretical maturation co-evolve. Special issues function as turning points: downside dynamics, whistleblowing, and heroic screens formalize consequence sensitivity and contestation, while later conference and legacy issues consolidate pluralism and reflexive ethics. The article contributes (a) an explicit coding and audit method for reading a journal as a field-forming narrative and (b) …

Efficacy Of Glp-1 And Gip/Glp-1 Receptor Agonists On The Body Weight Management Of Obesity, Paige D. Timbrook

Seaver College Research And Scholarly Achievement Symposium

Obesity is a major epidemic across the United States, and weight loss through diet and physical activity alone is not sustainable. Treatment with tirzepatide and semaglutide have proven to be effective for obesity management in the short-term, but more research is needed to understand how certain types of medications impact weight loss over time. In this study, we recruited 42 adult participants with or without Type II diabetes who were 21 years and older, taking only one GLP-1 or GIP/GLP-1 receptor agonist at a time, had a beginning body mass index of 30 or greater or a beginning body mass …

Identification Of Covalent Catechin Adducts Of Enoyl-Acp Reductase (Fabi) From E. Coli Using Mass Spectrometry, Francisco G. Atwi, P. M. Joyner, Rustin Ghidari

Seaver College Research And Scholarly Achievement Symposium

Enoyl-ACP reductase (FabI), an enzyme which is inhibited by catechin, is essential for lipid biosynthesis in bacteria (E. coli). Another FabI inhibitor, triclosan, has strong antibacterial effects,1 but overuse can be detrimental to the environment. Flavonoids, a class of dietary compounds, are known to have potent inhibitory effects on FabI and other kinases.2,3,4 Adducts form as a result of the biochemical reaction between flavonoids and cysteine, a modification which can be verified by m/z shifts on the mass spectra.5 Samples of E. coli protein with overexpressed FabI are utilized: the wild type with ordinary primary structure, and mutant type lacking …

How To Effectively Trap Invasive Crayfish: A Discrete Life Stage Mathematical Model, Rini Pattison

Seaver College Research And Scholarly Achievement Symposium

The red swamp crayfish is an invasive species introduced into several streams within the Santa Monica Mountains (SMM). Crayfish predation decimates native aquatic species. The Mountains Restoration Trust (MRT) has worked to remove crayfish through regular trapping in Malibu Creek.

A prior student created a crayfish life cycle model with trapping, which we expand to better predict the efficacy of crayfish removal efforts in the SMM. We separate crayfish based upon life stages and sizes. We construct and parameterize this discrete crayfish population model with and without trapping. We use literature and crayfish removal data from MRT to fit the …

Counting Hamiltonian Cycles In Quartic Circulant Graphs, Allison Hilliard

Seaver College Research And Scholarly Achievement Symposium

We consider the problem of counting Hamiltonian cycles in circulant graphs $C^K_n$ where $n$ is the number of vertices and $K$ is a set containing elements that correspond to the allowed edges in the circulant graphs. After sorting the cycles by a topological invariant called the winding number, we use a modified transfer matrix method to convert local data into global structures. The result is a generating function that counts the number of Hamiltonian cycles in a circulant graph with $n$ vertices. The results for $K=\{1,2\}$ and $K=\{1,3\}$ have been found by previous authors. We focus on the case where …

The Role Of Political Orientation In The Relationship Between Masculinity Threat And Pain, Bethany Kronlund, Randy Corpuz Ph.D., Dr. Elizabeth Mancuso

Seaver College Research And Scholarly Achievement Symposium

This experimental study aimed to explore whether political orientation might moderate the relationship between threatened masculinity and pain tolerance among 128 college men. Research has shown that the manipulation of gender stereotypes and how it affects pain tolerance in men has yielded mixed results. We administered a bogus gender knowledge test with fake feedback placing participants into either a masculinity threatening condition or masculinity affirming condition. This was followed by a pain tolerance test using a pressure algometer, where pain tolerance, pain threshold, perceived unpleasantness, and perceived painfulness were recorded. We hypothesized that men in the threatened masculinity condition would …

Tipping Points In Crayfish Management: Exploring Population Dynamics With The Bifurcations Activity In Slopes, Evan Inrig, Benjamin Lucas

Seaver College Research And Scholarly Achievement Symposium

Slopes is an interactive environment for exploring numerical methods and graphical solutions to ordinary differential equations. The app launched with five activities for exploration: slopefields, phase planes, oscillations, solutions to systems, and numerical methods for approximation. Bifurcations is a new sixth activity that we designed to investigate changes in the long term behavior of solutions to autonomous differential equations. This activity displays a slopefield and implements the ability to add solutions, but also introduces two new views that show how varying a single parameter impacts the values and stability of equilibrium solutions. We demonstrate the value of the new bifurcations …

The Role Of The "Indulgent Mindset" As A Modulator For Neuropsychiatric Biomarkers And Self-Reported Mental Wellbeing, Riva Ranier, Anika Anika, Sarah Simon, Ethan Chau, Emma Monte, Madison Retzloff, Johann Luna, Susan Helm

Seaver College Research And Scholarly Achievement Symposium

The Role of the "Indulgent Mindset" as a Modulator for Neuropsychiatric Biomarkers and Self-Reported Mental Wellbeing

Objective: Limited understanding persists regarding how an "indulgent mindset" about food shapes neuropsychiatric outcomes. Building on the "milkshake study" demonstrating that mindset modulates ghrelin response independent of nutritional content, this pilot study examines whether an indulgent mindset intervention affects neuropsychiatric biomarkers and mental wellbeing.

Methods: Women ages 19-65 (n=35; intervention n=17, control n=18) completed a 6-month randomized trial with baseline and post-intervention assessments including 3-day food diaries, mental wellbeing questionnaires, and comprehensive metabolomics (Iollo panel across mental health, metabolic health, gut microbiome, brain health, …

Statistical Inference Is Not Moral Reasoning: The Case Against Ai On Hospital Ethics Boards, Elan J. Haronian

Seaver College Research And Scholarly Achievement Symposium

As generative AI becomes more integrated in healthcare, it seems inevitable that AI will eventually be used on hospital ethics committees. However, before implementation, their roles need careful consideration. Although AI promises to reduce costs, increase efficiency, and reduce human workloads, there are important ways in which it is limited, especially when human emotion and connection are crucial, as in clinical ethics boards.

In this paper, I highlight several problems preventing AI from being useful on hospital ethics boards. These include issues of opaque reasoning (the “black box” problem), liability, transparency, privacy, and consent. While there are proposed frameworks for …

Investigating Best Practices In Diagnostic Reasoning And Differential Diagnosis: Implications For Occupational Therapy, Frank Czuba Drot, Otr/L, Laila Atra-Yassin Ots, Cassidy Green Ots, Shaylynn Krause Ots, Stephanie Petersen Ots, Alisa Robinson

Research Days

Diagnostic Reasoning and Differential Diagnosis (DD) are increasingly vital in occupational therapy (OT) practice as direct access legislation expands evaluative responsibilities for occupational therapy practitioners (OTPs). Despite this need, little research has explored how OTPs understand and apply diagnostic reasoning in clinical contexts. This study examined processes, strategies, and perceived barriers and facilitators influencing OTPs’ engagement in diagnostic reasoning and DD across diverse settings. A national online survey of licensed OTPs collected quantitative and qualitative data on knowledge, confidence, training, interprofessional collaboration, and clinical behaviors. Data were analyzed using descriptive and inferential statistics, weighted analyses, z-scores, and thematic analysis. Results …
