Another “Tone Test” Moment: Authenticity, Ai, And The Admission Essay, Peter Tschirhart

Journal of the National Collegiate Honors Council Online Archive

Debates about “authenticity” are not new but cyclical, and insights from music history and performance studies can illuminate how we evaluate student work in an age of machine collaboration. At the turn of the twentieth century, Edison’s “tone tests” blurred the line between human and machine by staging performances in which audiences were challenged to distinguish live singers from phonographic recordings. These events inaugurated a century-long debate about authenticity in music, one that resonates strongly today as educators confront new challenges posed by large language models (LLMs). Drawing on Auslander’s (2023) account of liveness, authenticity in writing—like authenticity in music—can …

Generative Ai And The Honors Thesis: A Rhetorical Framework For Gai Policy, Pedagogy, And Equity, Sean Chadwick

Journal of the National Collegiate Honors Council Online Archive

This article offers a rhetorical framework for understanding how honors students engage with the capstone thesis following the emergence of generative AI (GAI) tools. Author reviews the nature of the honors thesis and analyzes some rhetorical models for thinking about GAI and literacy before offering a heuristic framework identifying four interdependent skill categories—writing, social, executive, and subject matter—that shape students’ thesis work. Drawing on findings from an interview study, this framework clarifies how GAI tools interface with existing thesis practices and pain points, allowing honors practitioners to better articulate our values, evaluate use cases, and craft GAI-informed policy. As a …

Motivational Factors Influencing Honors Student Attrition: An Expectancy–Value Perspective, Nina Marijanović, Naomi Rowland, Morgan Flanagan, E. Myo Zin, Megan Bailey

Journal of the National Collegiate Honors Council Online Archive

This study investigates the motivational factors underlying student withdrawal from an honors college using expectancy-value theory (EVT) as a guiding framework. Drawing on qualitative analysis of self-reported withdrawal forms (n = 1,110) collected between 2018 and 2023 at a midsize public university, authors identify the core drivers of attrition across three constructs of EVT: expectancy (belief in one’s ability to succeed), value (perceived benefits of participation), and cost (perceived burdens or tradeoffs). Findings indicate the most common motivations as value-related concerns, including misalignment with academic goals or career trajectories. Cost-related factors, such as workload demands, scheduling conflicts, and financial …

Framework For Integrating Industry Knowledge Into A Large Language Model To Assist Construction Cost Estimation, Prashnna Ghimire

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

The construction industry generates a large amount of data across projects produced by digital devices, tools, and methods, and this volume is rapidly increasing. However, the industry lags behind in adopting data-driven technologies. On the other hand, the rapid advancement of generative AI (GenAI) in recent years, especially state-of-the-art large language models (LLMs), shows great potential and has been increasingly adopted in many industries; however, the construction industry is behind in adoption. While academic studies have proposed various machine learning applications for construction, industry implementation has lagged due to a disconnect between these proof-of-concept developments and practical industry needs. Also, …

Genetic And Soil Influences On The Grapevine Rhizosphere Microbiome, Lauren M. Quackenbush

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

In vineyard cropping systems, the rhizosphere microbiome arises through recruitment and filtering of the bulk soil microbiome shaped over time by soil carbon and nitrogen, climate, pH and historical legacies of vineyard management. The recruitment and filtering steps occur under the genetic influences of rootstock and scion that together drive variability in rhizosphere microbiome diversity and composition.

This study compares rhizosphere microbiomes of four Pinot Noir blocks under two rootstocks (101-14 and 420A) and four scions (777, 828, Calera, Mt. Eden). Core microbiomes were consistent across all replicates. The most abundant bacterial phyla were Actinobacteriota, Proteobacteria, and Acidobacteriota …

Amplification In Mems Rlc Circuits For Enhanced Sensitivity And Mems Applications, Mutaz Mohd Hamdi Al Fayad

Durham School of Architectural Engineering and Construction: Dissertations, Theses, and Student Research

Micro-electro-mechanical systems (MEMS) have garnered significant attention due to their unique characteristics, including small size, high sensitivity, and cost-effective mass production.

Next-Generation Biomedical Implants And Stimuli Responsive Soft Optical Arrays Via Surface Functionalized Elastomeric Materials, John M. Kapitan

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

The demands of emerging technologies, such as soft robotics, stretchable electronics, and next generation biomedical implants, has led to the development of diverse polymeric and hybrid organic/inorganic materials specifically tuned to meet these challenges. These materials typically have low Young’s moduli and are inert with high chemical stability. However, this has led to materials that are static in nature, lacking any meaningful way of responding to changes in their environment and adapting to these changes. This has driven a shift towards the design, manufacturing, and characterization of various stimuli responsive surfaces, relying on precise control of surface chemical coatings and …

Evelyn Waugh And The Problems Of Representing Conversion, Alec J. Miller

Department of English: Dissertations, Theses, and Student Research

Evelyn Waugh’s conversion to Catholicism in 1930 raised the question of how his writing would change. The satires he wrote before his conversion, Decline and Fall (1928) and Vile Bodies (1930), are hilarious but have no spiritual vision. Critics attacked his second novel after his conversion, A Handful of Dust (1934), for not being fitting for a Catholic writer to have made. Yet, Waugh makes a religious point in A Handful of Dust, exploring the wages of spiritual apathy without showing a path out. Later in Waugh’s career, he makes his finest attempt in the Sword of Honour trilogy …

Enhancing Remote Sensing Imagery Temporal Resolution Using Starfm Data Fusion Approach For Improved Land Surface Monitoring, Ahmadreza Pourghodrat

School of Computing: Dissertations, Theses, and Student Research

High-resolution remote sensing imagery plays a critical role in various domains, such as farm-level agricultural operations, environmental monitoring, and natural resource management. However, data with high spatial resolution typically have low temporal resolution, and those with high temporal resolution often lack spatial detail. For example, Landsat 8 and 9 satellites deliver high spatial resolution images with a 30-meter pixel size but suffer from low temporal resolution, with a 16-day revisit cycle. In contrast, satellites like MODIS and VIIRS provide daily images but with a much coarser spatial resolution (375 meters or more), reducing spatial details. Additionally, there is a lack …

Optimizing Transcription Efficiency Through Mutations In The T7 Rna Polymerase, Claire N. Novak

Honors Program: Senior Projects (Public)

The production of RNA is vital for many commercial and research purposes, with one of the more notable reasons being vaccine production. The RNA polymerase, derived from T7 bacteriophage, is commonly used for RNA production due to its ability to produce full-length RNA transcripts. However, researchers have faced limitations in optimizing this polymerase. For example, the polymerase generates heterogeneous RNA products that require additional purification steps during RNA production. Here, we selected three amino acid point substitutions based on a recent publication from Moderna that showed increased RNA purity compared to the wild type T7 RNA polymerase sequence. We created …

This literature review examines the historical exclusion of Mexican American, Asian, and Black students in the United States. Important legal cases will be explored to trace the progression of educational equity in America. Several theories will be reviewed, including social identity theory, ecological …

Evaluation Of Gfap And Ptau Protein Expression In Male And Female Cci Mouse Models, Sara Wallace

Honors Program: Senior Projects (Public)

Traumatic Brain Injury (TBI) is a serious public health concern that leads to the death or disability of thousands of individuals in the US annually. Progression of TBI involves primary damage from the initial, mechanical injury and secondary damage, from nonmechanical, pathological dysfunction. The secondary damage mechanisms can be better understood, diagnosed, and treated through the quantification of TBI biomarkers. The two biomarkers of interest in this study are pTau and GFAP. The male and female mouse models showed similar significant increase in GFAP following injury, as well as a general lack of increase in pTau expression following the injury. …

Scalable Mxene-Based Textile Supercapacitors, Abaigeal Aydt

Department of Food Science and Technology: Faculty Publications

Industrialization adversely affects the gut microbiome and predisposes individuals to chronic non-communicable diseases. We tested a microbiome restoration strategy comprising a diet that recapitulated key characteristics of non-industrialized dietary patterns (restore diet) and a bacterium rarely found in industrialized microbiomes (Limosilactobacillus reuteri) in a randomized controlled feeding trial in healthy Canadian adults. The restore diet, despite reducing gut microbiome diversity, enhanced the persistence of L. reuteri strain from rural Papua New Guinea (PB-W1) and redressed several microbiome features altered by industrialization. The diet also beneficially altered microbiota-derived plasma metabolites implicated in the etiology of chronic non-communicable diseases. Considerable …

Gravel Road Performance Enhancement, Bora Cetin, Kristin Cetin, Charan Sai Vangaveeti, Mehdi Bulduk, Md Mahir Asif

Nebraska Department of Transportation: Research Reports

Nearly 30% of roads in the U.S. are unpaved, significantly impacting rural connectivity with Nebraska alone having approximately 75% unpaved roads. This study systematically evaluates local materials to improve gravel road performance, reduce maintenance frequency, and decrease financial burdens on counties. Survey responses revealed that nearly 70% of counties follow NDOT specifications for gravel road design, while more than 90% lack knowledge of local material quality. The most common distresses identified were raveling, loss of crown, dust, and improper drainage. These findings indicate that construction practices rely heavily on experience, rather than systematic design, highlighting the need for a performance-based …

Racial Powers, Talhah Mustafa

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

This dissertation will be divided into three papers that in some way considers the concept of racial powers. The concept of racial power is under-researched and presupposed in the Philosophy of Race literature. Many arguments in this field seem premature without a general understanding of racial powers. The first paper fills that gap by introducing and defending the view that racial powers are possessed in virtue of one’s race or perceived race.

In the second paper, I consider Chike Jeffers’ cultural constructionist account of race. The nature of race is complex, requiring nuanced consideration. Chike Jeffers’ cultural constructionist may seem …

Data consisted of observation, images from arts-based workshops and pre- and post-workshop interviews with selected teachers …

Nebraska Crop Budgets Updated For 2025, Glennis Mcclure

Cornhusker Economics

For the 2025 production season, 83 crop budgets were developed for Nebraska. These budgets show slightly lower per-unit costs compared to 2023 and 2024. The primary factor behind the reduction in input costs is the lower estimated costs of fuel and fertilizer. In most cases, machinery depreciation and opportunity costs remained relatively stable, while land values and rental rates increased slightly. Additionally, seed and interest costs also rose in the 2025 budgets. Budget scenarios for individual producers may vary depending on the timing of their input purchases and fluctuations in prices.

The Nebraska crop budgets are updated annually to serve …

Exploring The Pathogen Profiles Of Ancient Feces, Drew Capone, David Holcomb, Amanda Lai, Karl Reinhard, Joe Brown

Karl Reinhard Publications

Analysis of ancient desiccated feces – termed paleofeces or coprolites – can unlock insights into the lives of ancient people. We collected desiccated feces from caves in the Rio Zape Valley in Mexico (725-920 CE). First, we extracted DNA with methods previously optimized for paleofeces. Then, we applied highly sensitive modern molecular tools (i.e., PCR pre-amplification followed by multi-parallel qPCR) to assess the presence of 30 enteric pathogens. We detected ≥1 pathogen associated gene in each of the ten samples and a mean of 3.9 pathogens per sample. The targets detected included Blastocystis spp. (n=7), atypical enteropathogenic E. coli (n=7), …
