Wheat, War, And Water: The Making Of Food Insecurity In Afghanistan, Karam Alkaissy Mr.

RURALS: Review of Undergraduate Research in Agricultural and Life Sciences

This paper attempts to explain why Afghanistan's exceptional dependence on wheat has produced one of the world's most severe food crises, as the crop's dietary centrality collides with environmental stress, political upheaval, and shifting agricultural systems. The FAO projects that 17.4 million people - roughly 40 percent of the population - will experience acute food insecurity in 2026; wheat supplies up to 57 percent of caloric intake, making this dependence a profound source of vulnerability. Examining wheat through culinary, climatic, political, and agricultural lenses, the paper shows that water lies at the heart of the crisis. Climate change is reducing …

Crustal Structure Of The Vøring Plateau And Vøring Spur From Joint Refraction And Reflection Travel-Time Tomography, Anika Nawar Mayeesha

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Crustal architecture of the Vøring Plateau and Vøring Spur in the mid-Norwegian continental margin remains debated because the geophysical data in the area do not uniquely constrain whether the crust is continental, oceanic, or transitional. This study reanalyzes wide-angle ocean-bottom seismometer data from Profile 11-03 across the Vøring passive continental margin using joint travel-time tomography of crustal refractions and Moho reflections. A total of 6,760 first-arrival picks and 542 PmP picks from sixteen instruments were inverted for P-wave velocity and reflector depth. Three starting models were inverted independently to test sensitivity to the initial crustal configuration. The first two used …

Beyond Borders: Educator Identity Development Through Sustained Intercultural Engagement In Rotary Youth Exchange, Lisa L. Waechter-Cass

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

This qualitative study employed collaborative narrative inquiry, informed by autoethnographic reflection, to examine how sustained intercultural engagement through Rotary Youth Exchange (RYE) shaped my evolving educator identity, self-efficacy, and enactment of globally responsive teaching within a rural elementary classroom. Guided by McAdams’ Narrative Identity Theory and supported by Bandura’s Self-Efficacy Theory, the study explored how long-term intercultural relationships and reflective dialogue influenced my understanding of teaching, learning, belonging, and global citizenship.

Data sources included reflexive journals, semi-structured interviews with former Rotary Youth Exchange students with whom I developed enduring family relationships through hosting experiences, and personal and educational artifacts …

Leading While Black: An Examination Of The Black Supervisor Experience Overseeing White Subordinates In Higher Education, Colette Marie Tobias

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

This study examines how systemic racism and social capital hierarchies shape the supervisory experiences of Black supervisors. While existing literature has explored leadership and race, it has not fully examined how systemic racism shape Black supervisors’ experiences or how social capital hierarchies play into the behavioral responses of white subordinates. This study addresses that gap by centering the lived experiences of Black supervisors within higher education.

Grounded in narrative inquiry, this research focuses on how participants make meaning of their experiences through their stories. Data was collected through semi-structured interviews and reflective journals with 19 Black supervisors who had at …

A Pedagogy Of Connection: Potentials And Practices For The English Classroom, Alexandra Bissell

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

In a moment characterized by rapid technological advancement and sociopolitical volatility, the academy currently faces the need to redefine what a college education can offer students and reimagine how it delivers on that promise. This dissertation proposes a pedagogy centered on the process of connection as one way that English educators at the collegiate level might approach our teaching and respond to this call. Connection is relational, but also textual and conceptual, and I contend that establishing connection as the catalyst for our pedagogical practices is a powerful way to move forward and support our students’ intellectual growth as well …

Dividing To Survive, Fight, Or Ally: Understanding Terrorist Group Splintering, Makayla Wendland

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

The splintering of terrorist groups is extremely common, with members breaking from the ranks of an existing organization to establish a new, independent organization. At times, the process of splintering has produced some of the deadliest terrorist groups globally, significantly affecting the trajectory and intensity of conflict. Conversely, there are times when splintering can produce groups that quickly dissipate without having an impact. This variation in lethality frames the question at the center of this dissertation: how do splinter groups behave and operate in their conflict landscape?

I develop a new theory-based typology to explain variations in the behavior and …

Rehumanizing Anatomized Individuals: Using Osteobiographies As A Step Towards Reparative Justice, Lillie C. Turpin

Department of Anthropology: Theses and Student Research

In 1985, India banned the export of human remains. This ended the major trade route for primarily US and European anatomical supply companies. Until this point, companies like Carolina Biological Supply exploited and erased vulnerable people's identities, molding them into anonymous anatomical specimens. This study investigates the life and postmortem history of twenty-five individuals, previously used as anatomical specimens, housed at the University of Nebraska–Lincoln. Using an osteobiographical approach, this research reconstructs aspects of these individuals' lived experiences and examines how anatomical preparation practices reflect structural violence and apathy.

Skeletal analysis of twenty-five individuals revealed a range of biological profiles, …

The "Evil Forest" As Threshold: A Computational Eco-Feminist Study Of The Forest In Nigerian Fantasy, Cynthia O. Mbagwu

Department of English: Dissertations, Theses, and Student Research

This study examines the representation of the “evil forest” in Nnedi Okorafor’s Zahrah the Windseeker and Ukamaka Olisakwe’s Don’t Answer When They Call Your Name, arguing that the forest functions as a liminal threshold that catalyses female transformation. Combining close reading with computational tools like TF-IDF keyword extraction in Ruby and sentiment analysis using VADER, the project investigates how pre-colonial and colonial connotations of the “evil forest” are re-imagined in contemporary Nigerian fantasy fiction. By segmenting each narrative into pre-liminal, liminal, and post-liminal phases, the study tracks shifts in sentiment toward the forest and correlates them with thematic developments …

Passive Microwave Remote Sensing Of Flash Drought Impacts On Vegetation, Quinton R. Deppert

School of Natural Resources: Dissertations, Theses, and Student Research

In 2002, Dr. Mark Svoboda characterized a new form of drought known as flash drought. Flash drought was defined as a rapid decline in vegetation health caused by severe heat and drought. In recent years, attempts to quantify the impacts of flash drought via precipitation, soil moisture, evapotranspiration, and temperature indicators have proliferated. What has rarely been quantified is what the rapid decline in vegetation health amid flash drought looks like through remote sensing. This is because vegetation health indices like the Normalized Difference Vegetation Index (NDVI) are derived from the visible and infrared regions of the electromagnetic spectrum and …

Good Life Automobility: Cultural/Rhetorical Resistance And Persistence Of Us Car Hegemony, Trinity O. Thompson

Department of Communication Studies: Dissertations, Theses, and Student Research

This project takes the car as a historical signifier of a rhetorical racialization process that enables a hypermobile white, masculine, neoliberal identity that pervades conceptions of mobility in the West. I locate these overlapping social formations under a cultural logic of good life automobility (GLA) that positions cars, a quintessential form of private property, as a motivator for a contemporary “good life” citizenship identity that cultivates neoliberal subjectivities of free movement and market consumption in contempt of socialized and racialized public transit futures. The introduction chapter elaborates on the boundaries of GLA while also contextualizing the two analysis chapters through …

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 …

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 …

Redefining Professional Boundaries To Strengthen Relationships And Postsecondary Goal-Setting: An Improvement Science Approach To Coaching Opportunity Youth, Felipe De Jesus Longoria-Shinn

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

Transitional and independent living coaches at Central Service Agency (CSA), a pseudonym for a Midwestern human services organization, support opportunity youth—young people facing systemic barriers—in improving their life trajectories. Although CSA has served an increasing number of youth in recent years, the number pursuing postsecondary education has remained stagnant or declined. This study engaged coaches, staff, and participating youth in an improvement science (IS) initiative designed to increase the number of postsecondary goals set by youth. Grounded in research demonstrating that postsecondary pathways can mitigate the effects of adverse life experiences and promote long-term mobility, this study examined how relational …

Identifying And Prioritizing Habitat For Ring-Necked Pheasants (Phasianus Colchicus) Conservation In Nebraska, Allison Joy Barg

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

As competing demands grow on agricultural landscapes, optimizing land use for economic and environmental benefit is crucial. A key way to improve conservation outcomes on working lands is to strategically target conservation efforts to land that is likely to provide the maximum benefit; however, this approach requires sufficient data to predict the outcomes of varying management decisions. Ring-necked pheasants are a recreationally and economically valuable species that were historically abundant in the agricultural regions of North America. The intensification and simplification of farm systems over the last half century have caused pheasant populations to decline, and while conservation programs such …

Perceived Barriers To Integrated Crop–Livestock Systems: Evidence From A Nebraska Producer Survey, Omid Tarashtwal

Department of Agricultural Economics: Dissertations, Theses, and Student Research

Integrated crop-livestock systems offer agronomic, economic, and environmental benefits, yet reintegration has been slow across the Northern Great Plains despite sustained interest. Existing research has documented barriers to transition conceptually, but quantitative evidence on which barriers producers perceive as most important and which producer and operation characteristics are associated with stronger barrier perceptions remains limited. This thesis addresses that gap using data from the 2023 Nebraska Agriculture Operator Survey.

The analysis focuses on 241 Nebraska producers, including 179 crop-only and 62 livestock-only operations. Seven models are estimated, combining ordered logit estimation for single-item barriers with linear regression for averaged barrier …

Evaluation Of Transportation Policy Effectiveness In The United States: Case Of Personal Electric Vehicles And Commercial Electronic Logging Devices, Hania Afzal

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

Together, electric vehicle (EV) adoption and the electronic logging device (ELD) mandate illustrate two dimensions of transportation technology policy: the first driven largely by environmental and market-based incentives and the second by safety regulation and compliance requirements. Examining these cases side by side for the United States allows for a more comprehensive analysis of how technology adoption unfolds under different policy regimes, offering insights into the broader relationship between policy design, industry response, and public outcomes. The commercial motor vehicle (CMV) sector presents a different but equally important policy challenge in transportation technology adoption. Unlike consumer passenger vehicles, CMVs are …

Tallina Linnahall: Arquitectura Soviética Y Mundo Prehispánico, Isabel Bargallo, Montserrat Bargalló Sánchez

Actas seleccionadas del SIMPOSIO ARTE 4.2: Migraciones en la imagen prehispánica: transitando territorios del pasado al presente. 58º Congreso Internacional de Americanistas, Novi Sad, Serbia, 2025.

Existen construcciones que nos recuerdan morfológicamente aspectos de la arquitectura precolombina que no tienen, en principio, relación cultural alguna con el pasado mesoamericano y que no responden tampoco a la función que desempeñaban las construcciones originales, o quizás sí. Éste es, sin duda, el caso del Linnahall de Tallin, donde no podemos dejar de preguntarnos los motivos que llevaron a unos arquitectos europeos, específicamente a dos profesionales estonianos, a inspirarse en las formas prehispánicas para proyectar y construir un espacio monumental que formó parte de las instalaciones de los Juegos Olímpicos de Moscú (1980) en la capital de Estonia. ¿Podemos …

Why Agtech Startups Fail? Evidence From Global Shutdown Patterns In 2025 And The Cost-Adoption Mismatch Effect, Ankit Chandra, Ishani Lal

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

Agricultural technologies are widely seen as a driver for sustainability, resilience, and food-system transformation. Yet in 2025, agtech startup across North America, Europe, Asia, and Africa experienced multiple shutdowns. Although each company closed for its own reasons, the failures highlight consistent underlying patterns. We analyze 18 publicly reported shutdowns across controlled-environment agriculture (CEA), robotics, insect protein, digital platforms, sensors, and ag-biotechnology. We find that most ventures struggled not with scientific feasibility but with economic and adoption dynamics at the farm level. We identify a Cost-Adoption Mismatch Effect, in which the capital and operational burden of a technology exceeds farmers’ capacity …

This project examined truck parking capacity, demand, and utilization patterns along I-80 in Nebraska. The objectives were to (1) document the capacity of public and private truck parking facilities along I-80, (2) analyze spatial and temporal trends in parking demand, (3) develop models to predict occupancy at parking facilities, (4) identify clusters of undesignated parking during inclement weather, and (5) assess whether truck parking shortages contribute to truck-involved crashes. Within a one-mile buffer of I-80, 21 public facilities and 49 private facilities were identified. The spatiotemporal analysis of these public and private truck parking facilities using the National Agriculture Imagery …

Unsettling The West: Migration Routes And Homesteading Through Oral Histories, Sidney Wickham

Nebraska Anthropologist

Westward expansion in the nineteenth-century United States has long been framed through settler-centered historical narratives that emphasize progress and national development. This article employs oral history as an ethnographic method to examine migration routes and homesteading experiences in Nebraska and the broader Midwest, foregrounding how memory, storytelling, and lived experience function as cultural practices. Drawing on interviews with descendants of homesteaders, community members, and museum professionals, alongside diaries, newspapers, and archival materials, this study analyzes how migration was remembered, narrated, and transmitted across generations. Rather than treating overland trails and homesteads as singular pathways of movement, this research situates them …

A Semiotic Analysis Of German-American Cultural Suppression In The Lincoln Freie Presse From 1914 To 1918, Elle Ward

Nebraska Anthropologist

This study performs a historical semiotic content analysis of the Lincoln Freie Presse to document the processes of cultural coercion and resultant identity erasure within the German- American press of Nebraska during the critical period of January 1914 to December 1918. The research establishes a semiotic baseline (1914–1916) characterized by high linguistic and content autonomy and then tracks the immediate, stark shifts following the U.S. entry into World War I (the coercion period) and the succeeding mass anti-German hysteria (1917–1918). Quantitative findings convey a rapid and overwhelming visual conquest of the newspaper’s spatio-textual landscape: patriotic symbolism surged from zero to …
