Herbicide Management For Bromus Tectorum To Enhance Rangeland Productivity In Western Nebraska, Miranda Mueller

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

Cheatgrass, Bromus tectorum (L.), has increased in the mixed-grass prairies of the Nebraska Panhandle. Limited research is available in these ecosystems on the ecological factors that influences its spread and options for management. This study focuses on the efficacy of herbicide treatments (indaziflam and imazapic) as a cheatgrass control method on the native rangelands of western Nebraska. In September of 2022, a mixture of indaziflam (73 g ai ha^-1, Rejuvra) and imazapic (70 g ai ha^-1, Plateau) was aerially applied at 6 unique upland ecological sites (1-3 ha) near Scottsbluff, Nebraska. Functional group plant biomass data …

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 …

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 …

Navigating Generative Ai In Honors, Anne Dotter, Victoria M. Bryan

Journal of the National Collegiate Honors Council Online Archive

Considering the historical significance and pedagogical impact of educational technologies on teaching and learning in higher education, authors suggest that generative artificial intelligence creates more questions than solutions for honors practitioners. What might meaningful AI literacy look like throughout a multidisciplinary honors curriculum? To what extent will generative AI level educational inequities, or create new ones? If policing AI misuse is ultimately a losing battle, how might this understanding reshape assignment design, assessment practices, and even our definitions of academic dishonesty? Drawing on examples in current teaching practice, authors observe the two sides of generative AI—one holding powerful possibilities for …

Ai Responsibilization: Shifting The Burden Of Academic Integrity, Daniel A. Cryer

Journal of the National Collegiate Honors Council Online Archive

Because AI text generators like ChatGPT give students unprece-dented power to outsource their work, concerns about academic integrity are escalating among instructors. This essay suggests that the proliferation of generative artificial intelligence in teaching and learning dramatically shifts the burden of academic integrity, typically shared between teachers and students, onto students. The concept of responsibilization, a defining feature of neoliberal societies in which individuals become responsible for costs and tasks once shouldered collectively, is a useful lens through which to view this new reality. Rather than policing students’ work, educators should recognize the new responsibilities conferred onto students by learning …

Pull Up A Chair, Deep Blue: Ai In Honors Education, Betsy Greenleaf Yarrison

Journal of the National Collegiate Honors Council Online Archive

Generative AI is the latest in a succession of technologies that allow us to do with machines what we used to have to do by hand. This essay argues that the elements of teaching in honors that can be automated probably should be and that it is the role of honors faculty to teach students how to distinguish superior thought from mediocre thought, good questions from great ones, and solid supporting evidence from weak or biased counterparts. Large learning models (LLMs) only collate what is already known and cannot teach thinking. As an information delivery system, AI can narrow the …

Teaching Ai Literacy Through Science Studies, Rhetoric, And Ethical Reasoning, Michael J. Klein, Philip L. Frana

Journal of the National Collegiate Honors Council Online Archive

Building on the idea of productive troublemaking, this essay presents a team-taught interdisciplinary honors course that integrates science and technology studies, rhetorical analysis, ethical reasoning, and artificial intelligence policy. Rather than framing AI as a threat, this course invites honors students to experiment with AI technologies and develop competencies by analyzing AI as a social and subjectivity-shaping phenomenon—writing policy briefs, producing rhetorical analyses of science fiction, and completing self-paced AI literacy modules. Honors education is uniquely positioned to model responsible and human-centered uses of intelligent systems, thereby cultivating graduates who can both use and critically interrogate the AI tools that …

News From The Front: How To Win The Ai War, Christine Haverington

Journal of the National Collegiate Honors Council Online Archive

While artificial intelligence is currently and justifiably a hot topic among scholars and university administrators, students are way ahead of the curve in terms of its use and application. Calling for educators to stop trying to catch AI “cheaters,” this essay provides evidence from honors and other classroom observations, student research on peer and faculty usage and attitudes, course evaluations, and external sources to demonstrate how and why generative AI can be creatively and effectively incorporated into teaching. Toward this end, practical pedagogical strategies are shared describing teaching modalities and innovative curricular design, avoiding the cognitive degradation of students, and …

Harnessing The Power Of Ai In Honors: Equipping Students To Leverage Tools Effectively, Lindsey Roberts, Jesse Roberts

Journal of the National Collegiate Honors Council Online Archive

Rapid advancements of AI and its permeation across disciplines are driving its inclusion in higher education curricula in order to maximize graduate employability. AI education in honors must go beyond practical workplace readiness to include creative and critical engagement with the technology (e.g., understanding its conceptual foundations, domain-specific applications, and implications for ethics and governance). Without these essential components, the imparted knowledge of AI may age poorly and leave honors graduates ill-prepared to ethically and responsibly use artificial intelligence.

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 …

Honoring Intellectual Risk-Taking: A Dialogue, Julie Bowman, Alexis Teagarden

Journal of the National Collegiate Honors Council Online Archive

Presented in the form of a Socratic dialogue, this piece considers what honors courses should strive to teach. Bowman, an experienced instructor of both non-honors and honors classes, notes that while universities’ honors colleges prize intellectual curiosity, her honors students might not. Teagarden, the other interlocutor and a writing program administrator, wonders whether curiosity is a sufficient end goal for honors or any teaching. The speakers turn to whether curiosity or courage is the more important virtue to instill, explore a classical difference between courage and audacity, and then discuss whether and how courage could be taught.

Understanding And Addressing Mental Health In Honors Programs, Gavin D. Hood, Katherine H. Tennis

Journal of the National Collegiate Honors Council Online Archive

Evidence of psychological experiences unique to high-achieving students is examined, revealing prominent themes relating to student mental health including academic identity, perfectionism, imposter syndrome, burnout, and overcommitment. These themes are explored in the context of program feedback from honors students gathered through focus group meetings as part of the program review process. Strategies for reframing failure, normalizing self-care, fostering supportive community, and engaging in nonacademic self-exploration are included. The article closes with suggestions for programmatic interventions that directly address these concerns among high-achieving students. While most honors programs are not positioned to engage in clinical interventions, they can take small …

Connecting Classroom And Community: Building Ecosystems For Meaningful Alternative Breaks, Chelsea Redger-Marquardt, Jean A. Patterson

Journal of the National Collegiate Honors Council Online Archive

This essay presents best practices in experiential learning via an alternative break program at a large public research university. In this interpretative qualitative study, authors analyze on-trip reflective blogs of students participating in an immersive alternative spring break program focused on food and shelter insecurity in Washington, D.C. (n = 11). A sensemaking/sensegiving theoretical framework is applied to explore the role of program partnering between student affairs (alternative break) and honors (coursework). Findings suggest that special care and attention be given when creating strong, direct-service experiences through reciprocal community partnerships, creating spaces for reflection during the immersive experience, and …

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 …

Addressing Agricultural Mulch Challenges In Specialty Crop Production, Caleb David Wehrbein

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

Agricultural mulches are an essential yield-boosting tool in modern specialty crop production that provide weed suppression, temperature modulation, and moisture conservation functions. Polyethylene plastic mulches are the most widely used agricultural mulch but are not sustainable given their pollutive effect on the environment and challenges associated with recycling. In order to move towards a more sustainable industry, plastic mulch use in agriculture should become more efficient or replaced with more environmentally friendly alternatives. Biodegradable mulches may be a suitable alternative to plastic mulch, but they are often less durable and prematurely degrade in field conditions. Considering this, my dissertation research …

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 …

Aging-Related Hearing Decline And Resting State Networks, Cassidy S. T. Ellsworth

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

This study investigated the effects of age-related hearing decline on functional networks using resting-state functional magnetic resonance imaging (rs-fMRI). The main objective of the present study was to examine resting-state functional connectivity (rsFC) and graph theory-based network efficiency metrics in forty-nine adults categorized by age and hearing thresholds to identify the neural mechanisms of age-related hearing decline. RsFC within key brain networks and auditory-related brain regions, including the default mode network, salience network, dorsal attention network, and primary auditory cortices, was assessed using region-of-interest (ROI)-based and graph theory approaches. Functional metrics, such as rsFC strength and global and local efficiency, …

Clinical Case Study: The Effects Of Saltatory Pneumotactile Stimulation Of Glabrous Hand And Perioral Face On Cerebral Oxygenation, Cognitive Performance, And Sensorimotor Function In An Adult Following Left Hemorrhagic Stroke, Tara L. Hull

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

Stroke remains a leading cause of adult disability and a significant global health concern. Effective rehabilitation strategies for cognitive and communicative impairments following stroke are limited (Kuhn & Sharman, 2023). One emerging approach involves repetitive somatosensory stimulation to drive cerebral hemodynamic changes, potentially offering a novel rehabilitative method. Functional Near-Infrared Spectroscopy (fNIRS) is a non-invasive, accessible tool for monitoring these changes during stroke recovery. Prior studies suggest tactile stimulation rapidly affects brain hemodynamics (Custead et al., 2015; Oh et al., 2017). This clinical single-case study explored the use of GALILEO saltatory pneumotactile stimulation applied to the face and hand in …

Music And Word Learning In Children Diagnosed With Developmental Language Disorder, Rebekah G. Sweeney

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

Purpose: This study investigates whether incorporating music into vocabulary interventions improves rate of learning and retention of words in children with developmental language disorder (DLD). Emerging literature continues to show the plentiful benefits of music as a tool for intervention in many settings, including the world of speech pathology (Levitin, 2024). However, it is also evident that there is a connection between struggling with language, and struggling with musical elements, such as rhythm and pitch perception, particularly in children with DLD (Boorom et al., 2022; Kreidler et al., 2023). This study seeks to tease out if music is an effective …

Investigating Child-Informed Considerations For Animated Picture Symbols Representing Emotion For Aac Use In Children With Asd, Hannah Kitsmiller

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

Development of emotional competence is an important area of consideration when supporting individuals who use augmentative and alternative communication (AAC). Emotional competence includes skills related to identifying and communicating about one’s emotions. Individuals who use AAC may struggle to develop strong skills in emotional competence. One potential barrier to developing emotional competence may be access to symbols that facilitate understanding of the represented emotion. Emotions are abstract and challenging to represent in visual symbols. Additionally, evidence suggests individuals with autism spectrum disorder (ASD) may have visual perceptual differences when viewing faces. Current emotion symbols are often depicted using isolated facial …

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.

Reducing the required input voltage for electrostatic MEMS remains a key research focus.

This thesis investigates voltage amplification in electrostatic MEMS through integration with resonant RLC circuits. By leveraging resonance, optimized configurations are designed to maximize voltage gain and enhance the signal-to-noise ratio. Through theoretical modeling and simulations using MATLAB …

Controlling The Narrative: How The United Daughters Of The Confederacy Shaped Collective Memory Through Romance Novels, Karie L. Cobb

Department of English: Dissertations, Theses, and Student Research

While existing scholarship on the United Daughters of the Confederacy (UDC) reveals the immense influence the organization wielded in the nineteenth and twentieth centuries, I assert that their legacy has had a broader and more insidious reach than previously believed. Through close analysis of two foundational romance novelists’ works published during the rapid escalation of the genre’s popularity, I contend that the rhetoric of the UDC shaped generations of Southerners as demonstrated through repetitions and parallels of the Lost Cause ideology found in UDC publications and sponsored materials within romance novels written by white Southern women who came of age …

Impact Of Diet Quality And Functional Food (Honey) On Gut Microbiota And Metabolic Health In Obesity, Sarah M. Eaton

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