A Zariski-Nagata Theorem For Smooth Toric Surfaces, Jordan Vincent Barrett

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

The Affine Zariski-Nagata theorem is a classical result in commutative algebra that gives an expression for the n^th symbolic power of a radical ideal I in a polynomial ring over a field in terms of the n^th ordinary powers of the maximal ideals in [affine variety]_max(I). In this thesis we discuss a well-known projective analog of Zariski-Nagata and provide the necessary background on toric varieties to present a generalization of this result to toric surfaces. We conclude with a brief discussion about work toward characterizing which abstract toric varieties have smooth point fibers with …

Illustrating Identity: Ethel Reed’S Art Posters And Women's Claims To Public Space In Fin-De-Siècle Boston, Miranda R. Knofczynski

School of Art, Art History, and Design: Theses and Student Creative Work

Much scholarship has uncovered the history of women illustrators during the late nineteenth century. The rebuilding of these lost histories calls for research which theorizes women’s contributions to the burgeoning arts scene of the fin-de-siècle. This thesis will examine the posters Ethel Reed created for different companies during the height of the 1890s poster craze and discuss how she articulated women in public space in them. Reed’s art offers an aestheticized yet feminist visualization of women engaging in leisure activities such as exploring the city, reading, or attending the theatre. Many have described the women in her posters as merely …

Medusa's Metamorphosis: Art, Mythology, And The Changing Perception Of Female Power, Elizabeth Kehr

School of Art, Art History, and Design: Theses and Student Creative Work

The evolution of Medusa’s iconography in ancient Greek art mirrors societal and cultural transformations. As attitudes shifted in relation to gender roles, power relationships, and morality changed, so too did images of the Gorgon. Following the course of development of Medusa’s image allows one to discover details of the thoughts and struggles the ancient Greeks had with concepts of power, womanhood, and monstrosity and otherness. Previous art historical research on Medusa has largely examined her function and evolution of visual depictions from the Archaic monster to Classical ideal. Few, however, have explored how and why these changes may be indicative …

Investigating Fatty Acid Influence On West Nile Virus In Mosquitoes And Birds, Hayley Moree

Honors Program: Senior Projects (Public)

Vector-borne diseases, including Zika virus (ZIKV), Dengue virus (DENV), and West Nile virus (WNV), pose considerable global health threats, accounting for over 400 million infections and more than 700,000 deaths annually. Many vector-borne diseases are within the Flaviviridae family. Despite this, effective treatments have not been found for some flaviviruses. Flaviviruses exploit host cellular machinery to facilitate their replication and survival, reprogramming metabolic pathways, including lipid metabolism. Lipids play essential roles in the viral life cycle, providing structural components for the viral envelope, enabling membrane rearrangements for replication complexes, and supplying energy resources necessary for particle assembly.

Targeting lipid metabolism …

Novel Chloroviruses With Unique Glycans On Their Major Capsid Proteins, Cayden J. Homolka

Honors Program: Senior Projects (Public)

Chloroviruses, of the family Phycodnaviridae, are large, dsDNA viruses with a genome of 290 to 410 kb. These virus genomes are so large that they are classified as “giant viruses”. Within this genome, up to 16 tRNAs and 330 to 450 proteins are encoded. Among the massive amounts of genes and proteins are unique carbohydrate synthesis/metabolism genes, which are responsible for the glycosylation of chloroviruses major capsid proteins. In most viruses, these proteins are glycosylated by the host enzymes located in the endoplasmic reticulum. Instead, Chloroviruses encode their own glycosylation machinery; essentially decorating themselves. Furthermore, these chlorovirus glycans are unlike …

Stop Design: Rethinking The Approach To Public Transit's Architecture, Elizabeth M. Nielsen

Architecture Masters of Science Program: Theses

Public spaces are the foundation of our social health and wellbeing, but are often designed without considering the needs of the public, creating spaces that people do not feel encouraged to use. Just as public space design as a whole often falls short of serving the public, the same can be said for a subset of public space design, public transit stops. While they are public spaces created for the purpose of waiting, their design rarely reflects this.

Well-designed public transit stops are capable of both maintaining existing ridership and drawing in new riders. Most commonly, this design occurs at …

Recognizing Injustice, Reclaiming Voices: Establishing A Missing Persons Database For Missing And Murdered Indigenous Women And Children In Nebraska, Bayly W. Watson

Department of Anthropology: Theses and Student Research

Indigenous people have been the victims of harsh persecution since the time of colonization; this has negatively impacted Native communities and has contributed significantly to the ongoing crisis of Missing and Murdered Indigenous Women and Children (MMIWC) across the United States and Canada. Under Legislative Bill 154, Richards et al. (2021) conducted an initial study to identify missing Native cases in Nebraska and in 2023, the Attorney General appointed a Missing and Murdered Indigenous People (MMIP) Liaison to help combat the number of missing Indigenous in the state. This thesis contributes to previous research by analyzing 20,049 reports from three …

Heat Induced Diagenesis And Osteometrics: An Experimental Approach To Assessing Thermal Alterations To Forensic Anthropological Data On Dry Bone, Audrey Holbeck

Department of Anthropology: Theses and Student Research

Fire appears in forensic casework in instances of arson, vehicle fire, house fire, to conceal evidence, or, in increasing contemporary frequency, wildfire, as a result of climate change. Thermal alteration is a destructive process to osseous material and can impact the accuracy of identification methods and trauma analysis by alteration of the structure, appearance, and morphology of human remains. This study seeks to validate previous research on the metric and morphological changes bone undergoes when exposed to extreme heat, and how that may impede estimation of metric features such as stature. Three long bones, a humerus, femur, and tibia, from …

Comparative Analysis Of Gunshot Trauma And Decomposition In Southeast Nebraska, Alexandra C. Tieken

Department of Anthropology: Theses and Student Research

Accurately identifying gunshot trauma (GST) in forensic anthropology remains a significant challenge, particularly in distinguishing the effects it has on decomposition. This study investigates how different types of gunshot trauma influence the rate and characteristics of decomposition in a humid continental climate, specifically southeastern Nebraska. Utilizing Sus scrofa domesticus (domestic pigs) as human proxies, four pigs were euthanized by professionals and subjected to controlled conditions at the Reller Prairie Field Station. Three pigs were inflicted postmortem with close-range gunshot trauma using a 9mm handgun, a 12-gauge shotgun, and an AR-15 rifle, while a fourth served as a trauma-free control. For …

Wildfire And Decomposition: A Taphonomic Analysis Of Thermal Alterations And Decomposition, Ashley Novak

Department of Anthropology: Theses and Student Research

Within the field of forensic anthropology, practitioners may be faced with remains that have been thermally altered by thermal alterations caused by wildfire. Within the field, very little research has been conducted examining how these thermal events impact rates of decomposition. While research has been conducted generally on the effects of thermal alteration on decomposition, these studies do not look through this lens and provide answers to the question of how do thermal alterations caused by wildfires affect rates of decomposition? This research examines the effects of thermal alteration caused by wildfire on the rate of decomposition. A decompositional study …

Trends In Dna Aanalysis To Determine Postmortem Interval: A Systematic Lilterature Review, Victoria S. Kashkin

Department of Anthropology: Theses and Student Research

Forensic taphonomy is a recently popular field within forensic anthropology with limited research in the Central Great Plains. Given decomposition varies by region, more studies must be done to understand aspects of decomposition in this region. However, it is one of the most important subfields of forensic anthropology since determining postmortem interval (PMI) is extremely important to successfully identifying a missing individual if other indications of who the individual is are nonexistent. In this study, a systematic literature review was conducted to answer what trends are seen in research being done for using DNA to determine PMI, and what methods …

Empowering Diversity: A Comprehensvie Approach To Minority Risk Management Education, Jahqethea Johnson

Applied Science Program: Theses

Federal programs are pivotal to the foundation of the United States agricultural sector. Program payments impact the economic well-being of agricultural producers, yet accessibility, outreach and education disparities remain prevalent among socially disadvantaged producer and agriculturists. From 2020-2024, an average of $21.7 billion dollars in federal agricultural payments have been paid to producers. Although federal funding historically supports commodity crops, livestock producers also depend on a distinct set of federal risk management programs, which are often less visible but pertinent for operational sustainability. There is a growing focus on the need for addressing disparities faced by socially disadvantaged producers and …

Quality Considerations In The Pedestrian Realm: Dead Space Intervention And Prevention, Alycia Ramage

Masters in Architecture Program: Theses

What if every space deemed “unadmirable” was reimagined as a stage for community life? Efforts to find solutions to this question prompted a more complex question: how can new construction promote interaction between architecture and the pedestrian realm?

This thesis is conducted in three main parts: 1) understanding dead space, 2) reinventing dead spaces in existing conditions, and 3) creating a design handbook that works to minimize dead spaces in new design.

Using Lincoln, Nebraska as a case study, part one begins with observation- looking for spaces that could be deemed unadmirable by a pedestrian. Utilizing research and observation, the …

Mediated Dwelling: Reconstructing The Contemporary Home Space, Nicholas Carraher

Masters in Architecture Program: Theses

As online social media platforms become dominant areas for self-expression, professional opportunity, and cultural exchange, the role of typical residential architecture in contemporary society is changing to meet the demands of this visually driven and performative culture. Social media’s emphasis on aesthetic appeal, shareability, and curated authenticity challenges traditional architectural paradigms that prioritize functionality, spatial quality, and privacy. This change coincides with the broader Western cultural shift in ideals and social dynamics of the contemporary user. The home space, a once-private refuge, has been redefined in the age of online social media, where physical space is endlessly curated to align …

From In-The-Head To In-The-World: Frameworks For Understanding And Applying Computational Thinking, Justin Olmanson, Gretchen K. Larsen, Azadeh Hassani

Department of Teaching, Learning, and Teacher Education: Faculty Publications

In the five decades since Papert coined the term Computational Thinking (CT), it has become a core framework for thinking about learning, problem-solving, design, and creativity. Although CT is most commonly, and initially, associated with the cognitive orientations involved in coding and learning to code, it also includes situated and critical processes related to computational problem solving. Herein we unpack ways researchers in different fields and points in time have organized CT. We include creative coding as a uniquely generative lens for rethinking CT, outlining its potential as an expressive, constructionist, and culturally situated practice. In doing so, we explore …

Exploring Constructionist Pathways For Generative Ai In Education, Gretchen K. Larsen, Justin Olmanson, Azadeh Hassani

Department of Teaching, Learning, and Teacher Education: Faculty Publications

In this study, we aim to better understand the effects of generative AI within a constructionist learning design. We explore participants’ experiences in a graduate level course on Artificial Intelligence in Education, where generative AI is studied as: a cultural object to understand and critically evaluate, an interactive learning technology, and a creative material generator. Students explored AI in education via Python, philosophical and empirical scholarship, and generative AI. They applied this knowledge to the design and prototyping of a learning technology related to their professional backgrounds and interests. Methodologically, our study offers an ethnographic description of constructionist approaches to …

Mitigating Nitrogen Losses: The Role Of Enhanced Efficiency Fertilizers In Sustainable Corn Production, Dipesh Giri

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

Nitrogen (N) is essential for crop production, but its inefficient use often leads to environmental losses through nitrate leaching, ammonia volatilization, and nitrous oxide (N₂O) emissions. Enhanced efficiency fertilizers (EEFs), such as nitrification inhibitors (NIs) and urease inhibitors (UIs), have been developed to minimize these losses and improve nitrogen use efficiency (NUE). This research combined a multi-year field experiment and a controlled laboratory study to evaluate how dual-inhibitor fertilizers compare to conventional urea and single-inhibitor formulations in Nebraska cropping systems. The main objective was to understand how nitrogen inhibitors influence N availability, crop performance, and nitrogen losses across different environmental …

Improving Nitrogen Management And Corn Productivity Through Enhanced Efficiency Fertilizer And Cover Crop Integration In Nebraska Cropping Systems, Madhusudhan Adhikari

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

Effective nitrogen (N) management is vital for sustaining corn yield and reducing environmental impacts in Nebraska cropping systems. Three field studies were conducted to evaluate the impact of 1) fertilizer type (anhydrous ammonia [AA] with nitrification inhibitor: enhanced efficiency fertilizer [EEF] or AA without EEF) and N application timing (pre-plant vs. split with side-dress UAN) on in-season soil N availability, crop response, nitrous oxide (N₂O) emissions, residual soil N and N use efficiencies (NUEs); 2) winter cover crop (CC) species and crop rotation variability on CC biomass production, N uptake, soil N dynamics, and cash crop performance in …
