Predicting The Future Of Myanmar’S Civil War: Can Half A Century Of Military Rule Be Defeated?, Nathan Ritterling

Honors Program: Senior Projects (Public)

In 2021, the military of Myanmar launched a coup in response to their overwhelming defeat in the 2020 elections, resulting in an end to the country’s tentative move towards democracy and in intense violence to suppress opposition to the coup. Anti-junta forces quickly formed in the aftermath to directly oppose the military and return the country to democratic rule, and began collaborating with long-standing ethnic militias in their efforts. This has led to a state of prolonged civil war, as the two sides fight for dominance over the nature of Myanmar’s future government. This paper investigated the potential outcome of …

Curriculum For All: An Introduction To Calculus, Maggie Scott

Honors Program: Senior Projects (Public)

Math is one of the only subjects that builds upon itself throughout a student’s educational career. Progressing through each course, students are taught concepts that build upon each other year after year. The content is engaged with itself, yet, it’s historically taught in a non-engaging way. Through my research of math education and my experience as a math teacher, it’s apparent that the most successful math classrooms are the ones that elicit student thinking and allow for self-discovery. (Azad)

Most people have very polarized views of math. Some love it, and some hate it, but almost all students can remember …

Coarse-Work: An Investigation Into The Impact Of Materiality In The Interior Educational Setting, Isabel G. Robb

Honors Program: Senior Projects (Public)

Education design in modern suburban America curates learning environments that are cold and impersonal, being used more as a place to keep youth during the day than as a place where they can truly learn about and understand the world around them. This learning environment does not suit all students, especially those with learning disabilities, and it leaves little room for flexibility in classroom usage.

Focusing on creating a learning environment where all students feel welcome and are able to effectively learn, this projective design research project aims to provide a comprehensive intervention through the built environment and interior design, …

A Grim End For Europe's First Civilization: The Fall Of Minoan Crete, Ashley Arp

Honors Program: Senior Projects (Public)

Early popular theories about the collapse of the Minoan civilization center around natural disasters, but geoarchaeological research from the past few decades has disproved these earlier theories. It is evident that the Minoan civilization continued to thrive for around a century after the volcanic eruption and subsequent tsunami that had previously been credited as the cause for the collapse. Evidence of manmade destruction has been uncovered across the island of Crete c. 1450 BCE and this period was quickly followed by a drastic cultural shift that included more Mycenaean elements than had been found on the island previously. These destructions, …

Biological Teleology In The Modern World, Kathryn Siena

Honors Program: Senior Projects (Public)

In humans, the heart moves blood through the body. Does the heart therefore have a teleological explanation? Aristotelian teleology (described in Aristotle’s Physics) is the cause-for-the-sake-of-which, or the end towards which something moves. It is evident from current scientific knowledge that there is some sort of orientation of organisms toward an end. This orientation, following Aristotle’s definition of teleology, is conceptually distinct from efficient causation. This orientation is also metaphysically distinct from efficient causation because efficient causal explanations do not properly describe the orientation. However, two common ways of describing teleological explanations imply efficient causation as a metaphysical element. …

Mathematical And Computational Analysis Of Certain Regularizations For The 3d Navier-Stokes Equations And Nonlocal Peridynamic Conservation Laws, Isabel Safarik

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

Voigt regularization is a technique used to model turbulent flows, offering advantages such as sharing steady states with the Navier-Stokes equations and requiring no modification of boundary conditions. We explore a modification to the Voigt regularization technique by introducing fractional dissipation into the system, specifically incorporating a fractional power, r. In this work, the proofs are in the context of periodic boundary conditions. The resulting fractional Navier-Stokes-Voigt (fNSV) and fractional Euler-Voigt (fEV) equations are studied for global well-posedness in three dimensions. It is shown that global well-posedness holds in the 3D case for fEV when the fractional power r …

Ecological Dynamics Of Cenozoic North American Mammals, Alexandria Brandis Shupinski

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

Understanding how community structure is affected by various ecological, climatic, and environmental changes is a long-standing goal in ecology. However, disentangling human impacts from these other variables is difficult when using short modern timescales and anthropogenically altered communities. The fossil record provides a means to investigate community structure dynamics across critical intervals, excluding humans as a variable. Here, in three studies, I assess changes in North American mammal paleocommunity structure across the last 66 million years (Ma) at multiple temporal and spatial scales. In Chapter 1, I identify changes in mammal functional diversity (FD) locally and continentally, using three independent …

Investigating Large Repeats In The Arabidopsis Thaliana Mitochondrial Genome Using Mitotalens, Megan Gusso

Honors Program: Senior Projects (Public)

This lab project explores the complexity of the mitochondrial genome by investigating large genomic repeats and their effect on flowering plants’ reproduction and viability. Mitochondria are the site of cellular respiration to create energy and contain their own DNA. This is counterintuitive because the byproducts of cellular respiration impose a threat of mutation for the stored DNA. The mitochondrial genome differs in size between animals and plants. Plant mitochondrial DNA is larger due to the presence of large, noncoding repeated sequences, and a large amount of DNA of unknown function. These sequences undergo high levels of recombination and rearrangement. The …

Decolonizing The Western Perception Of Afghan Women: A Feminist Critique, Parwana Azimi

Honors Program: Senior Projects (Public)

Abstract: Feminist theory and activism have often been reduced to singular movements from Western literature and history. Thus, the exploration of Feminist theory is often limited to Western ideology and values. In doing so, Western Feminism has primarily promoted the rights of Women living in developed countries while leaving women in developing countries or otherwise out of the discussion of women’s rights and status. Most often, women's rights struggles outside of the West are seen as colonial projects which portray Muslim women as helpless and requiring liberation from their cultures. A prominent example of this is the case of Afghan …

Drag Reduction In Channel Flow Configurations For Laminar And Turbulent Flow Past Superhydrophobic Surfaces, Henry Louis Ems

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

In this work, we present friction drag reduction in minichannel laminar flow past superhydrophobic metallic surfaces. Femtosecond laser surface processing (FLSP), a one-step scalable method, was used to create permanent microscale and nanoscale structures on 316 stainless steel plates. The resulting superhydrophilic plates were covered by tall (215 μm) or short (27 μm) structures. The FLSP plates were then transitioned to superhydrophobic by evaporative deposition of a fluorinated silane, a low surface energy coating. Using purified water, the friction factor was obtained by measuring pressure drop along a minichannel with a rectangular cross section for flow rates corresponding …

Aggregate Games: Computations And Applications, Jared Soundy

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

Existing computational game theory studies consider compact representations of games that capture agent interaction in real-world environments and examine computation aspects of computing equilibrium concepts to analyze or predict agent behavior.

One of the most well-studied representations that capture many commonly studied real-world environments is aggregate games. Aggregate games, first systematically studied by Nobel laureate Reinhard Selten, have various applications in modeling the decision-making interdependence of agents, where each agent’s utility function depends on their own actions and the aggregations or summarizations of the actions of all agents. These applications include Cournot oligopoly competition, public good contribution, and voting, where …

Toxicological Effects And Treatment Of Accidental Ingestion Of Simparica Trio® In Felis Catus: An Investigative Review, Aussia M. Stander

Honors Program: Senior Projects (Public)

Simparica TRIO^®, a canine endectocide manufactured by Zoetis, contains sarolaner, moxidectin, and pyrantel pamoate salt in an orally administered chewable tablet. These compounds are all toxic to both cats and dogs in sufficient amounts. As Simparica TRIO^® rises in popularity among pet owners, Felis catus (felines, cats) in multi-pet households (households with both cats and dogs) are at increased risk of overdosage and toxicosis from accidental ingestion of Simparica TRIO^® due to their smaller weight.

Simparica TRIO^® is not for feline use and little literature exists on the symptoms of and treatment for accidental ingestion …

Consequences Of The Megafauna Extinction: Changes In Food Web Networks On The Edwards Plateau Across The Pleistocene–Holocene Transition, Quentin A. Smith Jr.

School of Biological Sciences: Dissertations, Theses, and Student Research

We are experiencing biodiversity loss due to climate change and human impacts, which is not only harmful to the environment but can also alter the composition of communities and interactions among species. The late Pleistocene experienced a loss of large-bodied mammals which resulted in significant changes in community structure due to changes in body size, diet, and species associations. The impact of these changes on species interactions and community structure across the Pleistocene-Holocene transition remains poorly understood. Using a robust data set of species composition, stable isotopes, body size, and climate variables, we constructed and compared ecological networks of mammal …

Artificial Insemination And Fetal Programming In Beef Production Systems, Dempster M. Christenson

Department of Animal Science: Dissertations, Theses, and Student Research

Pregnancy to artificial insemination and late gestation fetal programming of the next calf crop are central to genetic development, reproductive longevity, calf crop productivity, and efficiency of cow/calf ranching. The purposes of this research are to find methods to improve pregnancy rate to artificial insemination, the growth and reproductive health of pregnant heifers, and the productivity of their offspring. In the first of four studies we found that extending the period of progesterone administration in an estrus synchronization protocol did not significantly hasten estrus response or increase pregnancy rate to artificial insemination, but timing of estrus within the melengestrol acetate …

Nonlocal Frameworks For Differential Equations--Analysis And Numerical Investigations, Layla Montemayor

Honors Program: Senior Projects (Public)

Systems of differential equations have been employed successfully in nearly every scientific field, including natural phenomena, finance, A.I. and machine learning. In a classical set up, a differentiable equation will be associated with a number of initial conditions that will help determine a unique solution to the system. The setting of classical differential equations requires assumptions on the regularity or smoothness of the input functions. Thus, we cannot produce with classical differential equations solutions which are irregular or even have discontinuities.

To overcome some of these challenges brought up by investigations of irregular or singular behavior, different formulations of nonlocal …
