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 …

Design And Development Of A Passive Dust Protection System For Lunar Docking Operations, Simon Thengvall

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

Lunar docking systems face a unique set of environmental conditions that can create significant challenges for mechanical design. Among these, the abrasive nature of lunar regolith can impair the kinematic function of traditional terrestrial mechanisms as well as contaminate critical spacecraft components such as environmental seals, causing them to fail. For crew-rated docking systems, failure of these systems not only threatens mission success, but also crew safety, so dust protection is crucial for docking components. To address the concerns of regolith intrusion, the Simple External Attachment for Lunar Openings (SEALO) is developed as a key architecture for mechanism evaluation when …

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 …

Salon Music For Professionals: An Analysis And Performance Guide To Two Programmatic Suites For Flute And Piano By Theodor Blumer (1881–1964), Brenna Sherman

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

Theodor Blumer (1881–1964) was an early twentieth-century German composer, pianist, and conductor whose substantial contributions to the flute repertoire have received little scholarly attention. Despite his prolific output and close association with leading wind performers of his time, his music remains largely absent from contemporary scholarship and performance. This dissertation addresses that gap by presenting a comprehensive biographical timeline, defining Blumer’s compositional aesthetics, and completing an in-depth analytical examination of his programmatic works for the flute.

Drawing on primary source materials from Blumer’s estate—including personal correspondence, photographs, and dated manuscripts—this study constructs the first full biography of Blumer. Central to …

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 …

Problems With Small Drinking Water Systems In Developing And Developed Countries: How Do They Compare?, Kurt Kesteloot

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

This dissertation compares the factors that drive the long-term functionality of small drinking water systems (serving fewer than 10,000 people) in developing and developed country contexts, with a focus on groundwater supplies. Using regression analysis in SAS and complementary fuzzy-set Qualitative Comparative Analysis (fsQCA) for developing countries, the study integrates two datasets: 23 Engineers Without Borders project surveys (90+ variables across 14 countries) and a multi-year National Park Service inspection dataset (approximately 1,561 systems; 7,460 recorded deficiencies, enriched with U.S. Census ZIP-code aggregates). In developing countries, statistically significant predictors of success include government cash contributions (odds ratio [OR] ≈ 67.6), …

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 …

A Conductor’S Focus On The Preparation And Performance Of Timothy Takach’S Helios, Lester Ray Miller

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

Multimovement a cappella choral works have been composed and performed since the invention of printed music. When selecting such works, choral conductors often look to masterworks of the Renaissance or to the established works of modern composers. Timothy C. Takach (b. 1978) premiered the 12-movement a cappella choral cycle entitled Helios in 2019. Takach has become a celebrated composer whose works are performed by choirs across the country, yet little academic study has focused on his output. This document serves as a resource for the conductor who wishes to program Helios and as an aid in preparing for rehearsal. It …

A Daily Assessment Of Food And Alcohol Disturbance And Alcohol Intoxication As Predictors Of Sexual Violence Victimization, Amanda Elizabeth Baildon

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

Alcohol-involved sexual violence (SV) is a common and detrimental experience for young adult women. To supplement SV prevention strategies aimed at perpetrators, who are fully responsible for the occurrence of SV, risk reduction programs that target women’s drinking have been implemented with limited efficacy. To improve these programs, research must examine novel predictors like food and alcohol disturbance (FAD) that contribute to SV risk. FAD refers to compensatory behaviors (e.g., restricted eating, excessive exercise) to offset alcohol’s calories or enhance intoxication. Approximately 45% of young adult women engage in FAD, a practice that likely heightens SV risk by facilitating rapid …

An Annotated Bibliography Of Music For Flute Alone And Flute And Electronics By Lgbtq Composers, Bridget Hill

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

Throughout my formal music education and general music upbringing, I have noted the erasure of the LGBTQ identities of artists, composers, musicians, and historical figures from formal music curricula, and from the concert hall. In response to this erasure, I am increasing visibility through the act of record-keeping by taking inventory of the works written for flute by LGBTQ composers. In searching for flute music by LGBTQ composers, it became clear that works by these composers were not organized into a centralized collection, or body of work.

This document will start the process of record-keeping by collecting and annotating works …

External Force Control Of Transitional And Turbulent Flows, Cesar Alberto Leos

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

Turbulence in wall-bounded flows governs momentum transport, drag, and energy efficiency in a wide range of engineering systems, yet its response to external forcing remains incompletely understood across transitional and high Reynolds number regimes. This dissertation investigates an active flow control strategy based on spanwise external forcing and demonstrates how it modifies the dynamics of transitional and turbulent channel flows with the objective of identifying the mechanisms through which forcing alters transition, flow physics, and turbulent drag reduction.

Firstly, direct numerical simulations are performed to examine the subcritical transition under external forcing. The onset and sustenance of turbulence are shown …

Exploring The Relations Between Employer Beliefs And Workplace Practices: Organizational Factors And Autism Employment Outcomes, Melinda Ann Henson

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

Autistic individuals experience persistent employment disparities despite interventions targeting individual skills and supports, suggesting that workplace factors also shape employment outcomes. Self-Determination Theory (SDT) posits that workplace environments supporting employee autonomy, competence, and relatedness promote employment outcomes. This study examined SDT-aligned practices and tested associations between employer beliefs about autism as a form of neurodiversity, hiring receptivity, and employment outcomes for Autistic professionals. A preliminary aim was to evaluate the psychometric properties of a newly developed measure, the Workplace Inclusivity and Autonomy Survey (WIAS), designed to assess SDT practices via employer report. Participants included 43 professionals representing a range of …

German Is For You! The Making Of A High School Multikulti German Course, Jennene Aten

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

This teacher self-study examined the process of creating and teaching a multicultural German curriculum. This study necessarily involved observing students as they went through the semester of course work, but students are not the center of the research. I am. This research focuses on what I learned about teaching, specifically my teaching in my subject area and how I could improve my skills and methods.

Germany is an ethnically diverse nation but not usually thought of as such. The presentation of Germany in German language textbooks is generally portrayed as rather monochromatic. Students who study German, specifically in Fairfield, California, …

Improving Drought Science Communication And Accessibility, Lindsay Erin Johnson

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

Effective drought management depends not only on the accuracy of scientific data, but also on how that information is communicated and understood by diverse audiences. This dissertation examines drought communication through the lens of science communication, with a focus on improving readability, accessibility, understandability, and usability of drought information. Using a manuscript-style format, three studies investigate how drought information is written, delivered, and applied. Chapter 1 provides a brief overview and outline of this dissertation. Chapter 2 evaluates the readability of the U.S. Drought Monitor (USDM) national narratives over almost 8 years. Results show that these narratives are consistently written …

Making The Case For Spandex: The Nature Of Re-Novicing And The Merging Of Expertise For Former Elementary And High School Teachers Who Move To Teaching At The Middle Level, Elizabeth K. Boyle

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

As an academic coach in a large, Midwestern middle school, I noticed an influx of teachers with years of prior experience at the elementary or high school levels being hired to work with students in grades six through eight. Because they were already veteran teachers, they were not assigned mentorship, yet there were aspects of working in a middle-school setting that effectively “re-noviced” them (Hanuscin et al., 2020).

Knowing that cookie-cutter approaches to professional development and learning often do not meet the needs of adult learners, I sought information that would guide what professional growth opportunities could be provided to …

No Ash Will Burn, Blake Kinnett

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

No Ash Will Burn follows twin narrators Avery and Krista Harmon. After a boy their aged, named Oliver O’Hara, moves in next door, Avie begins playing music with him at the docks in their town. When their mother unexpectedly passes away, Avery leaves their small town of Monticello, Kentucky for Lexington, Kentucky, taking Krista’s dulcimer along with her. The dulcimer was built by their late father, who intended to build two, but passed away before he could complete the second, dedicated to Avery. The completed dulcimer has Krista’s name carved into the side. In Lexington, Oliver develops an original song, …

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 …

Leading With The Heart: Fostering Asset-Based Teacher Beliefs And Practices For Multilingual Learners Through Research–Practice Partnership In A Diversifying Suburban Elementary School, Valerie Anne Kyllmann

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

This mixed methods study is part of a larger research-practice partnership (RPP) between practitioners and researchers at a Midwestern suburban elementary school experiencing an increase in cultural and linguistic diversity. Like many U.S. schools, its teaching force is mostly White, middle-class, and female, creating not only a pedagogical gap, but also a belief gap about the linguistic and academic assets multilingual students possess. Grounded in linguistically responsive teaching, adult learning, and improvement science, this study explores how RPPs can leverage varying expertise in cycles of inquiry to co-create initiatives that foster asset-based teacher perspectives through building-wide events and professional development. …

Critical Edition Of El Libertador: A Symphonic Poem By Costa Rican Composer Julio Mata (1899–1969), Manuel Monge Mata

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

This project offers a critical edition of El Libertador, a symphonic poem composed by Costa Rican artist Julio Mata Oreamuno (1899–1969). The piece holds special importance in Costa Rican orchestral music and represents the symphonic poem genre in Latin American compositions. Although Mata is acknowledged as a key figure in the growth of Costa Rican musical institutions and composition during the twentieth century, much of his orchestral work remains rarely performed and not easily accessible to today’s performers.

The edition is based on manuscript sources kept in the Archivo Histórico Musical of the University of Costa Rica, consisting of …

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 …

An Analysis And Performance Guide Of Two Published Versions Of Jenni Brandon's Chansons De La Nature Pour La Clarinette, Joanne Lundahl

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

Jenni Brandon’s Chansons de la nature pour la clarinette presents the clarinet as a narrating voice, guiding listeners through seven movements inspired by Aesop’s fables as retold by Jean de La Fontaine. This document traces the work’s evolution from its original publication for unaccompanied clarinet to its later adaptation for clarinet and digital delay pedal, examining the influences that shaped the piece and the compositional traits that define Brandon’s style, including her use of motives, range, meter, and formal design. Drawing on interviews with Brandon and clarinetist Christopher Mothersole, it outlines the history of both versions and establishes a foundation …

“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 …

Enhancing Soybean Breeding Through Optimized Testing Networks And Sparse Designs, Arthur Martins Almeida Bernardeli

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

This dissertation addresses a central challenge in soybean breeding: how to make better selection decisions across diverse environments while working within the practical limits of field testing. Multi-environment testing is essential for evaluating breeding lines, but large testing networks are costly to maintain and difficult to interpret because genotype performance often changes across locations and years. At the same time, breeders must decide how to allocate limited field resources while still capturing the environmental and genetic variation needed for effective selection. Using yield, pedigree, genomic, and environmental data from the University of Nebraska–Lincoln Soybean Breeding Program, this dissertation explores practical …

Corrupt, Control, Repress, Noah Schimenti

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

This three-article dissertation discusses the competition for power and resources in regimes with weak or nonexistent democratic accountability. I begin with an overview in the introduction and then turn to the individual articles in each chapter. In chapter 2 I investigate the composition of post-conflict transitional power-sharing governments. I hypothesize that a greater number of rebel organizations included in the transitional government is associated with increased corruption levels. Using data on 44 post-conflict countries, I find little support for this hypothesis; the number of rebel organizations in the transitional cabinet has no effect on corruption levels.

In chapter 3 I …

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 …

Patient Facing Physical Therapy Clinicians’ Experience Of Leader Development Across Their Professional Span: A Phenomenological Inquiry, Judith R. Gelber

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

While healthcare professions call for leadership among its practitioners as a key function of practice, hospital systems typically employ a top town leadership structure. In physical therapy, leadership is centered around managers and educators. This leaves a gap in understanding about leadership at the level of the patient facing clinician. This study explored the experience of leader development across the career span of experienced patient facing physical therapists in the United States. The study used a hermeneutic phenomenological approach undergirded with leader development, experiential learning, and distributed leadership theories. Participant recruitment focused on patient facing physical therapists with ten or …

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.

I …
