Psychological Principles In Writing Center Consulting & Ai, Ella S. Hansen

Honors Program: Senior Projects (Public)

A third of those ages 18 to 24 have engaged with ChatGPT (OpenAI, 2025). The newest form, ChatGPT-4, is better at generating more plausible long-form essays and creative writing than ever before (Imran & Almusharraf, 2023), meaning that AI-assisted writing is prevalent at higher education institutions (Cardon et al., 2023) and in writing centers (Goulet, 2025). Limited research has investigated the impact of this on writing center consultants. This multidisciplinary study investigated how consultants feel about large language model artificial intelligence (LLM AI) and how it can impact the consulting process, through the lens of three psychological principles: empathy, social …

Honors Program: Senior Projects (Public)

This thesis is an outline of my advertising plansbook that examines how culturally adapted advertising for a single book affects perceived authenticity, emotional resonance, and purchase intent across three distinct markets: the United States, Brazil, and Vietnam. This study examines three culturally distinct markets to identify which advertising elements require full localization versus those where standardization is acceptable. By comparing adapted campaigns against a standardized approach, this research provides actionable insights for publishers navigating the efficiency-effectiveness trade-off.

The research questions asked:

-       How does culturally adapted advertising for the same book affect perceived authenticity, emotional resonance, and purchase intent across …

Rewriting The Boer ‘Slim’: Alice Stopford Green’S Reports On St. Helena’S Prisoner Of War Camp And Her Impact On British Views Of Boer Prisoners, Natasja A. Swanson

Honors Program: Senior Projects (Public)

Alice Stopford Green (1847 – 1929) was a prominent Irish historian and politician, known for her role as a political activist in the Irish Home Rule movement. Her lesser-known legacy is her investigative journalism on prisoner conditions in British prisoner of war camps during the Second Boer War (1899 – 1902). Her reports on Boer conditions in the Deadwood Prisoner of War Camp on the island of St. Helena reflected maltreatment and institutional abuse by the British Government. These discoveries supported the minority English opposition that thought that England was overstepping the rules of civilized warfare. Green was primarily concerned …

The Mysteries Of Postpartum Ocd: A Systematic Review, Taryn Shaffer

Honors Program: Senior Projects (Public)

Background: The research on postpartum mental health is growing, with most focusing on physical and sexual wellness, or well-known mental health symptoms such as psychosis, depression, and stress. However, as the research grows, so does the interest in lesser-known or under-considered postpartum mental health symptoms, including Obsessive-Compulsive Disorder (OCD). The focus of this research can be the exacerbation of already-present OCD symptoms, or the onset of them during pregnancy and the postpartum period. The purpose of this systematic review was to analyze research on OCD in pregnant and postpartum women. Specifically, the review included an analysis of measures used to …

The New York Times: A Strategic Audit, Kaylee Campbell, Cassidy June, Keira Cummins, Tanner Maas, Alyssa Fjelstad

Honors Program: Senior Projects (Public)

The New York Times is a legacy newspaper that has navigated a great many changes since its founding in 1851. The company rose to success with its traditional print journalism, but has now transformed into a largely digital, subscription-based business model that provides subscribers with access to news, games, recipes, podcasts, product recommendations, and more. This provides an excellent foundation for a strategic audit to understand how one of the giants of a dying industry has not only managed to stay alive, but to thrive.

A PESTEL and Porter’s Five Forces analysis reveals that The New York Times operates in …

Exploring The Biocultural Profile Of The Undocumented Populations Of The Sonoran Corridor: A Skeletal Assessment Of The Prevention Through Deterrence Strategy, Mary A. Vaughn

Department of Anthropology: Theses and Student Research

Over the last thirty years the mortality rate of the undocumented population at the US-Mexico border has risen, requiring methods distinguishing US-born individuals from immigrants to improve the likelihood of identification and repatriation through foreign consulates. Forensic anthropologists with the Pima County Office of the Medical Examiner (PCOME) have advocated for the use of the biocultural profile, combining the biological profile with factors including oral health, osteological stress, and personal effects. The biocultural profile serves two purposes, functioning both as a tool for identification and with which to document structural inequality within communities of origin.

This study examines changes in …

Understanding Roma Oppression In Europe Through Humantarian Forensic Analysis, Christal L. Quinn

Department of Anthropology: Theses and Student Research

This thesis examines the marginalization of Roma people in Europe, and how humanitarian forensic practices may help Roma communities in their quest for justice and recognition. The study draws exclusively on secondary information to examine the social, political, and legal issues affecting the Roma communities, who have endured centuries of institutional discrimination, marginalization, and violence. This thesis identifies ways in which systematic oppression continues to limit Roma communities’ access to education, housing, healthcare, and legal protection through a review of relevant literature and applicable theoretical frameworks. The study also examines the relevance of forensic science, particularly its humanitarian applications, in …

Evaluating The Impact Of Intercropping Vegetables And Cut Flowers On Yield And Conservation Biological Control, Alliance Igiraneza

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

Specialty crops such as vegetables are some of the most susceptible to yield losses and increased management difficulty over time due to pests. One of the potential solutions to this problem, which aims at ensuring the sustainability of the sector, is using conservation biological control practices such as intercropping to increase diversity, while maintaining the economic feasibility and profitability of the system. This study was conducted to evaluate the impact of this management practice using Bell pepper (Capsicum annuum var. King Arthur) as the main crop, intercropped with flowers including zinnia (Zinnia elegans var. Benary’s Giant), sunflower ( …

Cis-Variant Gene-Expression Association Analysis: A Targeted Approach To Identify Functional Cis-Regulatory Variation, Sofiya Arora

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

Phenotypic diversity in plants is largely driven by changes in gene function arising from mutations in both the coding and regulatory regions. Regulatory variation is particularly pervasive because it can fine-tune gene expression without disrupting protein function and is therefore less likely to be strongly selected against in natural populations. As a result, it has played a central role in evolution and domestication. In our previous genome-wide eQTL mapping study in maize, nearly two-thirds of the expressed genes were found to harbor detectable cis-expression quantitative trait loci (cis-eQTLs) with strong local effects on gene expression. Though these cis-variants are widespread, …

The Harvey Pittel Saxophone Quartet: Its History And Legacy In American Saxophone Quartet Performance, James M. Lawhn

Glenn Korff School of Music: Dissertations, Theses, Student Creative Work, and Performances

The saxophone quartet has emerged as a legitimate chamber ensemble in the United States through the sustained efforts of a small number of pioneering professional groups. Despite the central role these ensembles have played in shaping repertoire, performance standards, and public perception, their histories have often gone undocumented. Among the most influential of these groups is the Harvey Pittel Saxophone Quartet, an ensemble that maintained an unusually active national and international touring career for nearly four decades and helped establish the saxophone quartet as a viable professional model.

This document addresses a significant gap in the scholarly literature by presenting …

Breeding For Diverse Color And Protein Quality In Popcorn And Sweet Corn, Jonathan Niyorukundo

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

Sweet corn and popcorn are important crops consumed globally as vegetable and snack, respectively. They are deemed healthy foods due to high fiber and carotenoid contents, especially in yellow varieties. Commercial varieties are optimized for high-yielding agronomics, and previous efforts were made to improve specific macro- and micronutrient contents. Both sweet corn and popcorn have poor protein quality due to the inadequate essential amino acids such as lysine and tryptophan. Moreover, commercial varieties are predominantly yellow, thereby offering no diversity of other maize colors, which are potentially healthier and more appealing to the consumer. In this project, we sought to …

Centering Access: Reimagining Basic Writing Through Critical Disability Frameworks, Jason Burton Mccormick

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

Despite decades of scholarship arguing otherwise, developmental writing spaces are still often treated as places of deficit in higher education. This deficit positioning emerges in the ways the courses are discussed (as barriers and burdens to graduation), the way learners are imagined (being “unprepared” for college work), and the way placement is understood as punishment. Developmental educators continue to fight this stigma, but rely on stories of students “overcoming” rather than acknowledging that the stigma is a product of the institution and its discriminatory norms, not the offering itself.

My work reimagines the developmental writing classroom as an essential liminal …

Musical Affinities Between Ann Southam's Glass Houses And Canadian Fiddle Tunes With Performance Considerations For Glass Houses No. 5, Evangelia Nikolaidou

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

Ann Southam stands as one of Canada’s foremost minimalist composers. Her fifteen-piece piano set Glass Houses, composed in 1981 and revised in 2009, reflects the joyful, dance-like energy of Canadian fiddle music that inspired it. While Glass Houses has frequently been discussed within the context of minimalist composition, less attention has been given to the ways in which the work resonates with Canadian fiddle traditions. This document draws on existing scholarship on Métis, French-Canadian, Newfoundland, Anglo-Canadian, and Scottish fiddle traditions to trace and clarify structural, rhythmic, and textural affinities between Canadian fiddle tunes and Glass Houses. Focusing on …

Laser Microprocessing Of Metallic And Composite Materials: Nanosecond Pulsed Laser Surface Melting, Laser Shock Peening, And Femtosecond Laser Machining, Qiuchi Zhu

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

This dissertation comprises three parts addressing laser microprocessing of metallic and composite materials through nanosecond pulsed laser surface melting, laser shock peening, and femtosecond laser machining. The first part discusses nanosecond pulsed laser surface melting for corrosion mitigation in stainless steel. Commercial 304 stainless steel (SS) was first used to establish a processing window for stable shallow remelting and rapid resolidification. The approach was then extended to 304L/308L SS welded joints relevant to nuclear dry storage canisters. The results show that nanosecond laser surface melting refines the near-surface microstructures in the heat-affected zone and improved pitting corrosion resistance. Electrochemical and …

Integrated Approaches For Valorization Of Chicken Feather Waste: From Extraction To Application Of Keratin-Based Bioproducts, Muhammad Ehtasham Akram

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

This dissertation explores the optimization of chicken feathers keratin hydrolysate (CFKH) production using alkaline hydrolysis (AH) and sub-critical water hydrolysis (SCWH), focusing on acquiring high keratin yield in the hydrolysate. Then, CFKH along with other locally sourced materials, was used to develop bioplastics with regenerative agriculture properties (BioWRAP), with the ultimate objective of applying it as a soil mulch to suppress weeds in agricultural crops. This work also addresses challenges in process design and industrial scale-up of BioWRAP. Chapter 1 is a literature review that introduces terms like biobased, biodegradable, and bioplastics, materials and methods used to make bioplastics, and …

Carmen Manrique De Quintero: A Forgotten Legacy In Colombian Piano Music, Lina Maria Luisa Marín Diaz

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

This doctoral document investigates the life and piano works of Carmen Manrique de Quintero (1871–1931), a pivotal yet overlooked figure in Colombian music history. Positioned as a stylistic bridge between the nineteenth-century estética del salón [salon aesthetics] and the professionalization of the Colombian composer, Manrique de Quintero’s output represents a sophisticated synthesis of European forms and Colombian national rhythms. Despite her membership in the influential Garay artistic lineage and her prolific body of work, her legacy has suffered from editorial blurring, fragmented documentation, and systematic intellectual appropriation. Using a multidisciplinary approach of genealogical reconstruction and artistic archaeology, this study restores …

Electron Emission From Unactivated Gaas: Towards The Development Of Novel Sources Of Spin-Polarized Electrons, William Truslow Newman

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

Spin-polarized electrons are commonly emitted from GaAs photocathodes with treated surfaces in a process called negative electron affinity activation. These sources require stringent vacuum conditions that are often hard to achieve and lead to significant downtimes in experiments. In this dissertation, I present new investigations of electron emission from unactivated GaAs towards the development of novel sources of spin-polarized electrons. The work entails two primary directions. The first is the investigation of electron emission using multiphoton ionization processes enhanced by nanoscale surface structures. We explore GaAs electron sources including, shards, nanotip arrays of pyramid structures, wedges, and ion-milled tips. The …

Reconstructing Nebraska’S Late Quaternary Paleoenvironment, Landscape Change, And Human–Environment Dynamics Using Diatoms And Optically Stimulated Luminescence Dating, Gosia Mahoney

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

This dissertation examines Holocene environmental change and human–environment interactions in the Nebraska Sand Hills by integrating geomorphic, paleoenvironmental, and geochronological data. It presents three complementary studies that together explore how climatic variability, local landscape processes, and human activity influenced environmental systems.

The first study reconstructs the early Holocene evolution of a dune-dammed valley in the central Sand Hills. Stratigraphic, sedimentological, and diatom evidence indicate that eolian activity resulted in a blocked fluvial system, leading to elevated groundwater levels and the formation of a wetland that later developed into a lake. Notably, this transformation occurred under relatively dry conditions, demonstrating that …

“The Left Leg Is Not Well”: Identity, Economy, And Ability In Early Modern Drama, Emma D. Whaley

Department of English: Dissertations, Theses, and Student Research

The human reality of the disabled experience often goes overlooked by scholars analyzing early modern literature. Most scholarship seems to interpret disability as metaphorical without examining the human who experiences it. In this paper, I will be examining disability in three early modern texts as literal and inquire into the realities of the disabled experience for the characters. A Larum for London, The Shoemaker’s Holiday, and The Fair Maid of the Exchange all prominently feature a disabled character—Stump, Ralph, and Cripple respectively. These characters offer a depth of personhood rarely examined in early modern literary scholarship, even in …

Awareness, Protest, And Action: Women Science-Fiction Writers As Writer Activists, Carolyn Nolte

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

Following the end of World War II, science-fiction literature, which was mostly dominated by white male writers, experienced an increase in stories written by women writers. Of these postwar stories written by women, the three women writers in this dissertation imagined how their present-day experiences informed the future by exploring their concerns about humanity’s collective trajectory. By analyzing how their stories dramatize possible future social, psychological, biological, and environmental harms, this dissertation argues that these women writers’ works distinguish them as writer-activists, a concept I borrow from Rob Nixon’s work Slow Violence and the Environmentalism of the Poor.

Parents Under Pressure: Social Media’S Impact On Parents’ Mental Well-Being, Ali E. Shull

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

The rapid growth of social media has transformed how parents access information, evaluate their practices, and compare themselves to others. Although parenting content is widely consumed, limited research has examined its immediate psychological and physiological effects. The present mixed-methods study investigated how exposure to parenting-related social media content influences parental stress responses, affect, and parenting self-efficacy. Participants (N = 83) were randomly assigned to view either parenting-related videos (experimental condition) or non-parenting crafting videos (control condition). Physiological stress responses were assessed using heart rate variability (HRV) during baseline and video exposure. Participants also completed measures of negative affect and …

Transport Phenomena Of Multiphase Flow And Slippery Microsphere Suspensions In Confined Space, Ryan Haggerty

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

Understanding multiphase flow has many important environmental and engineering applications. For example, understanding gas flow in porous media is useful for energy storage, petroleum engineering, and contaminant cleanup. Nano- and microparticle transport is vital for enhanced oil recovery techniques and environmental contamination. Despite their relevance to environmental engineering, multiphase flows, especially with concentrated particle suspensions, are still a complex and developing topic. Additionally, hydrophobic surfaces are a relatively new area of research, for while the effects of hydrophobicity are observable, the mechanisms may occur on several scales. Hydrophobicity leads to a property called “slip,” which contradicts the traditional treatment of …
