Partitions Of R^N With Maximal Seclusion And Their Applications To Reproducible Computation, Jason Vander Woude

Department of Mathematics: Dissertations, Theses, and Student Research

We introduce and investigate a natural problem regarding unit cube tilings/partitions of Euclidean space and also consider broad generalizations of this problem. The problem fits well within a historical context of similar problems and also has applications to the study of reproducibility in randomized computation.

Given $k\in\mathbb{N}$ and $\epsilon\in(0,\infty)$, we define a $(k,\epsilon)$-secluded unit cube partition of $\mathbb{R}^{d}$ to be a unit cube partition of $\mathbb{R}^{d}$ such that for every point $\vec{p}\in\R^d$, the closed $\ell_{\infty}$ $\epsilon$-ball around $\vec{p}$ intersects at most $k$ cubes. The problem is to construct such partitions for each dimension $d$ with the primary goal of minimizing …

Unobtrusive Data Collection In Clinical Settings For Advanced Patient Monitoring And Machine Learning, Walker Arce

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

When applying machine learning to clinical practice, a major hurdle that will be encountered is the lack of available data. While the data collected in clinical therapies is suitable for the types of analysis that are needed to measure and track clinical outcomes, it may not be suitable for other types of analysis. For instance, video data may have poor alignment with behavioral data, making it impossible to extract the videos frames that directly correlate with the observed behavior. Alternatively, clinicians may be exploring new data modalities, such as physiological signal collection, to research methods of improving clinical outcomes that …

Economic Analysis Of Western Corn Rootworm Injury To Continuous Corn In Northeast Nebraska, Isadora Vercesi Bethlem

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

The most economically significant corn pest in the US Corn Belt is the Western Corn Rootworm (WCR), Diabrotica virgifera virgifera LeConte. This study compares a field experiment outcome of 4 different treatments against WCR, which consist of a rootworm Bt corn pyramid (SmartStax®) and non-rootworm Bt trait hybrid (VT2P), with or without the addition of the rootworm soil insecticide (Aztec®) to identify the risk-reward trade-off for each one of them. Observed prices were used for the years in the study (2020, 2021, and 2022), and low and high price scenarios were simulated for the period, to incorporate different dynamic relations …

Self-Assembly Of Exfoliated Graphene Flakes As Anticorrosive Coatings For Additive Manufactured Steels, Kaleb Hood, Wen Qian, Yi Xia, Savannah Krupa, Annie Dao, Sarah Ahmed, Samuel Olson, Nam Nguyen, Joseph A. Turner, Jun Jiao

Department of Mechanical and Materials Engineering: Faculty Publications

This study demonstrates the feasibility of using liquid exfoliation of expandable graphite into multilayer exfoliated graphene flakes (EGFs) to form a self-assembled thin film on an air–water interface. The film can coat the surface of additive manufactured (AM) steel substrates to enhance surface properties, specifically AM 316 stainless-steel (AM316), AM 8620 steel (AM8620), and samples of the same alloys made by conventional manufacturing (CM) processes. Liquid exfoliation offers a high yield route for an EGF coating that can cover up to 95% of the sample surface with a single application. The thin, flexible EGFs can coat a rough AM metal …

The Effects Of Inaccurate And Missing Highway-Rail Grade Crossing Inventory Data On Crash And Severity Model Estimation And Prediction, Muhammad Umer Farooq

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Highway-Rail Grade Crossings (HRGCs) present a significant safety risk to motorists, pedestrians, and train passengers as they are intersections where roads and railways intersect. Every year, HRGCs in the US experience a high number of crashes leading to injuries and fatalities. Estimations of crash and severity models for HRGCs provide insights into safety and mitigation of the risk posed by such incidents. The accuracy of these models plays a vital role in predicting future crashes at these crossings, enabling necessary safety measures to be taken proactively.

In the United States, most of these models rely on the Federal Railroad Administration's …

Arthur Miller, Death Of A Salesman, Paige Moeller

Johnny Carson School of Theatre and Film: Theses, Student Research, and Creative Work

In this thesis our rendition of Death of a Salesman turns the story by presenting it in the eyes of an African-American working man. With the influence of the infamous Arthur Miller, my take on this classic tale will demonstrate the maturity and elegance that I could manufacture during the intense process. The show had a surplus of challenges, one of the biggest being the content of the script itself with our contrasting vision, as well as sudden directorial shifts and character additions. This thesis will cover the entire process from initial designs, communication, tech process, and more. The complexity …

Make War To Make Peace: Themes Of War In Trombone Solo Literature, Ian Rutherford

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

The trombone has a relatively small amount of solo literature, especially for how long it has existed. Many professors only teach and perform an even smaller number of those pieces. Some works are compelling and captivating but rarely performed. The purpose of this document is to explore two lesser-known works that have an exciting connection; they are both works about war. I Was Like Wow for Tenor Trombone and Boombox by Jacob Ter Veldhuis (JacobTV) and Encounters IV for Tenor Trombone and Multi-Percussion by William Kraft are two original works for trombone that explore themes of war.

The pieces were …

Designing Programming Languages For Writing Maintainable Software, Aaron Friesen

Honors Program: Senior Projects (Public)

Maintainability is crucial to the long-term success of software projects. Among other factors, it is affected by the programming language in which the software is written. Programming language designers should be conscious of how their design decisions can influence software maintainability. Non-functional properties of a language can affect the readability of source code in ways beyond the control of programmers. Language features can cause or prevent certain classes of bugs, and runtime issues especially can require significant maintenance effort. Tools external to the language, especially those developed and distributed by language implementers, can aid in the creation of maintainable software. …

Self‑Objectification During The Perinatal Period: The Role Of Body Surveillance In Maternal And Infant Wellbeing, Lauren M. Laifer, Olivia R. Maras, Gemma Sáez, Sarah Gervais, Rebecca L. Brock

Department of Psychology: Faculty Publications

Pregnancy represents a unique time during which women’s bodies undergo significant physical changes (e.g., expanding belly, larger breasts, weight gain) that can elicit increased objectification. Experiences of objectification set the stage for women to view themselves as sexual objects (i.e., self-objectification) and are associated with adverse mental health outcomes. Although women may experience heightened self-objectification and behavioral consequences (such as body surveillance) due to the objectification of pregnant bodies in Western cultures, there are remarkably few studies examining objectification theory among women during the perinatal period. The present study investigated the impact of body surveillance, a consequence of self-objectification, on …

Opportunities For Learning And Social Interaction In Infant Sitting: Effects Of Sitting Support, Sitting Skill, And Gross Motor Delay, Kari S. Kretch, Emily C. Marcinowski, Hsu Lin-Ya, Natalie A. Koziol, Regina T. Harbourne, Michele A. Lobo, Stacey C. Dusing

Nebraska Center for Research on Children, Youth, Families, and Schools: Faculty Publications

The development of independent sitting changes everyday opportunities for learning and has cascading effects on cognitive and language development. Prior to independent sitting, infants experience the sitting position with physical support from caregivers. Why does supported sitting not provide the same input for learning that is experienced in independent sitting? This question is especially relevant for infants with gross motor delay, who require support in sitting for many months after typically developing infants sit independently. We observed infants with typical development (n = 34, ages 4–7 months) and infants with gross motor delay (n = 128, ages 7–16 …

Spectacle In The Roman Imperial Funeral Procession, William Smith

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

From the legendary foresight of Augustus, to the scandalous escapades of Nero and Commodus to even the philosopher emperor, Marcus Aurelius, much has been written. This thesis does not concern itself with the deeds of emperors, but rather their funerals. Imperial funerals in some ways were quite similar to their Republican era antecedents. They differed in spectacular ways. This thesis investigates the spectacle evident in imperial funerals and argues that their inclusion is not to honor the deceased but rather cement their place in the cultural memory of Rome by means of this performance. In addition, it examines the role …

The Woodcliff Experiment: Zooarchaeological Applications Using A Legacy And Cultural Resource Management (Crm) Faunal Collection, Matthew Zmijewski

Department of Anthropology: Theses and Student Research

Legacy archaeological collections are often underutilized despite their valuable research utility. Archeologists might pass over these collections for research due to the age of recovery, along with the manner in which they were sampled and excavated. This thesis argues that significant archaeological research questions can be answered using these collections. To demonstrate their research potential, the author analyzes past subsistence behaviors and seasonality of occupations using the faunal remains from the Woodcliff site (25SD31). Woodcliff is a A.D. 1650-1750 Protohistoric Pawnee village located in eastern Nebraska. The faunal collection derived from excavations at the site constitute both a legacy and …

The Decline Of Upland Birds In Nebraska: Maximizing Limited Habitat, Hunter Tesarek

Department of Environmental Studies: Undergraduate Student Theses

Ring-necked Pheasants were introduced into the United States around 150 years ago and since then have become an important species both culturally and economically. There population health is of growing concern as upland bird populations in much of the United States have been declining rapidly throughout the latter half of the last century. In Nebraska millions of acres have been transformed from habitat that benefits upland birds into row crop agriculture, mostly in the form of corn and soybeans. Rural Mail Carrier Surveys conducted for pheasants from 1960 through 2020 in comparison to change in acres harvested depict the relationship …

Identifying A Consumer–Producer Agricultural Knowledge Gap, Aspen Rittgarn

Department of Environmental Studies: Undergraduate Student Theses

The purpose of this paper and online survey was to see if an agricultural knowledge gap between consumers and producers be found. Low agricultural literacy rates can lead to misconceptions of the agriculture industry, unhealthy food choices, environmentally unfriendly product choices, food waste, etc. The hypothesis for this thesis is that those born in the mid1960s to early 1980s (Generation X) will be the start of an increased knowledge gap. The survey was compiled of both qualitative and quantitative questions and questions were inspired by American Farm Bureau’s AITC Benchmarks. Responses were analyzed and the results revealed that my participants …

A Multi-Case Examination Of Leadership Development Programs For Emerging Educational Leaders In K–12 School Districts, Jason Thomsen

Department of Educational Administration: Dissertations, Theses, and Student Research

In recent years, a greater emphasis has been placed on leadership development programs across a wide array of sectors in an effort to improve organizations. A growing body of research indicates that strong educational leadership practices have the ability to impact virtually all aspects of a school system. What is less evident in the research is how K-12 school districts utilize leadership development programs and make decisions regarding the implementation of those programs in order to cultivate educational leaders. The purpose of this multi-case study was to examine how K-12 school districts utilize leadership development programs and the role that …

Designing For Micropolitan Areas: A Public Library Design Manual For Adaptive And Circular Applications, Samantha R. Zeek

Masters in Architecture Program: Theses

A micropolitan statistical area refers to a geographic region in the United States that has at least one urban cluster of population between 10,000 and 50,000 people, as defined by the US Census Bureau. According to the 2019 Fiscal Year Public Libraries Survey, more than three-fourths of public libraries serve areas with fewer than 25,000 people in the U.S. (Frehill, et al. 2021). However, as new design techniques and advanced services are developed, they tend to be primarily implemented in libraries serving metropolitan areas, which only serve around a quarter of the US population, leading to an unequal distribution of …

Department of Environmental Studies: Undergraduate Student Theses

This study was conducted entirely online with occasional help from advisors and editors on zoom meetings. I completed the research in Lincoln, Nebraska. A meta analysis of online data has been conducted to form the answers to my hypotheses and research questions. I used specific keywords and phrases in research databases, and search engines such as google scholar to point me towards the answers I was looking for. The keywords and phrases were split up into four different categories which are mitigation techniques, ecosystems, fire severity: PNW, and fire season: PNW. The reason the topics land preservation and fire science …

Evaluating Planting Green And Herbicides For Integrated Weed Management And Their Effect On Soil Properties In Corn And Soybean In Nebraska, Trey Parker Stephens

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

Producers across the Midwest are finding new ways to implement cover crops into cropping systems and the practice of “Planting Green” is one of the newest uses of cover crops. When planting green, producers plant their row crops into actively growing cover crops and terminate the cover crop at time of planting or shortly after planting. This practice would allow for higher biomass accumulation of the cover crop and could aid in weed management of herbicide-resistant weeds. The objective of the first two studies was to evaluate planting green and its effect on soil-applied residual herbicides, weed management, dicamba/glyphosate-resistant soybean …

Plasticity Of Sorghum Biomass And Inflorescence Traits In Response To Nitrogen Application, Kyle M. Linders

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

Nitrogen is an essential nutrient required for growth and development in plants. Insufficient nitrogen availability can reduce vegetative growth and grain yield. However, nitrogen is a costly input for farmers, is energy intensive to manufacture, and runoff of excess nitrogen fertilizer impacts water quality. Compared to its close relative, maize, sorghum has much greater resilience to nitrogen and water deficit, and heat stress, allowing sorghum to be grown with fewer inputs and on marginal land. Variation in total biomass accumulation and grain yield between sorghum accessions, as well as between nitrogen conditions, can be largely explained by differences in vegetative …

The Gendered Experience Of Female Resident Assistants, Christa Rahl

Department of Educational Administration: Dissertations, Theses, and Student Research

This paper sought to answer, “What is it like to be a female resident assistant (RA) in a society that has historically privileged men?” I structured this as a phenomenology within the transformative paradigm. I interviewed four participants twice with a prompt between interviews and one participant once. These participants were at least 19 years old and had held been an RA for at least one school year during the last five years.

I worked in the realm of Joan Acker’s (1990) theory of gendered organizations. I specifically had findings within the constructions she wrote about such as the division …

Realizing The Good Despite Customer Mistreatment, Carissa Kim

College of Business: Dissertations, Theses, and Student Research

Unruly and rude customer behavior is on the rise. Estimates indicate that frontline employees experience ten episodes of customer mistreatment daily. Not only is customer mistreatment detrimental for the frontline employee (e.g., higher turnover, lower job satisfaction, lower well-being, and more), but also for customers that witness (e.g., emotional contagion) or engage (e.g., loss of morals) in these deviant interpersonal behaviors. Extending the body of research on customer mistreatment, my dissertation seeks to investigate silver linings or possible functional consequences of customer mistreatment. My dissertation draws from Emotions as Social Information (EASI) theory to investigate the outcomes of mistreatment in …

Exploring The Role Of Microrna-1 (Mir-1) On Skeletal Muscle Hypertrophy, Shengyi Fei

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Skeletal muscle hypertrophy is a complex process that involves a range of signaling pathways and transcriptional regulators. Many hormones and growth factors can activate key signaling pathways, such as the PI3K/AKT/mTOR, MAPK, and cAMP pathways, which play a crucial role in the regulation of muscle hypertrophy. In Chapter 1, we reviewed some of the hormones and growth factors known to be associated with skeletal muscle hypertrophy, as well as the function of these key signaling pathways, and revealed some unresolved issues. In Chapter 2, we explored the role of microRNA-1 (miR-1) in skeletal muscle hypertrophy and aimed to determine the …

The Examination Of Nonparametric Person-Fit Statistics As Appropriate Measures Of Response Bias In Ordered Polytomous Items, Mark F. Beck

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Survey research is ubiquitous within the social sciences; however, surveys are vulnerable to response biases. Response biases introduce construct-irrelevant variance into survey responses, which degrades the accuracy of conclusions drawn through the use of surveys. Nonparametric person-fit statistics have been shown to accurately identify response biases in dichotomous response data but are not well studied in polytomous response data. This study examines the accuracy of nonparametric person-fit statistics in polytomous response data. A 6 x 4 x 4 x 2 simulation study was conducted, with type of aberrancy (6), number of response options (4), dimensionality (4), and test length (2) …

A History Of The Representation Of Women In Clinical Trial: Implications For Modern Health Care, Madison Gulizia

Honors Program: Senior Projects (Public)

The male body is the medical baseline for all things regarding health care. Whether it is education or an actual trip to the doctor’s office, female bodies are still viewed as the “smaller male body.” The physiological differences in the male and female body range from the cellular level to whole body systems. These differences can mean millions of different things, depending on what avenue of discussion is taken. There are differences in the ways genes are expressed, leading to a variety in metabolic pathways, the digestive system, and the nervous system. A specific area that requires attention is the …

Importance Of Pelvic Floor Education And Rehabilitation Techniques For Adolescents And Young Adults: A Review, Katherine Laura Schmidt

Honors Program: Senior Projects (Public)

The pelvic floor is the collection of many muscles forming what is often called the pelvic girdle. Understanding the different muscles and their roles is an important part of pelvic floor education. Although both males and females have pelvic floors, there is a lack of knowledge of basic anatomy seen in adolescents and young adults. This review analyzes the importance of providing more education for students about the pelvic floor, gives examples of common pelvic disorders for young adults, and provides details on the physical therapy rehabilitation techniques offered today to treat these conditions.

An Analysis Of The Impact Of Strict Photo Id Laws On Election Turnout: Do They Discriminate Against Minority Voters?, Josh Gromowsky

Honors Program: Senior Projects (Public)

Over the last 20 years, states across the nation have passed photo ID laws requiring potential voters to provide a form of identification before they can cast their ballots. These laws have generated great controversy, with opponents of the laws accusing them of being racially discriminatory. Studies attempting to analyze their effects on turnout have resulted in differing results due to different methodologies, and no consensus has been reached in the academic literature regarding this topic. Recognizing that laws do not exist in isolation and that people can react to their implementation in different ways, this paper examines the effects …

Hubris And The Protection Of The Citizen Body, Lillyan Uhlmann

Honors Program: Senior Projects (Public)

The Classical Greek notion of hubris, which relates most closely to a modern form of disrespect, was an important form of protection for the citizen body. The law of hubris fell under the public sphere of graphai, which allowed for any individual in the community to bring up a charge. The law of hubris protected not only male citizens, but also women and slaves, which emphasizes the protection of the society as a whole. Hubris was a way to check those of power in society and charges of hubris, if proven, could result in the revoking of citizenship or political …
