Status And Enhancement Of Trissolcus Japonicus (Ashmead) (Hymenoptera: Scelionidae) For Biological Control Of Halyomorpha Halys (Stål) (Hemiptera: Pentatomidae) In Northern Utah, Kate V. Richardson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The invasive brown marmorated stink bug (BMSB) is a major insect pest that invades human structures causing nuisance issues and attacks numerous fruit and vegetable crops in Northern America. As this pest threatens $23 billion worth of specialty and agricultural crops in the U.S. and is difficult to manage due to insecticide resistance, control practices such as the use of biological control through egg parasitoid wasps are critical. In its native range of Asia, BMSB populations are controlled primarily by members of the Trissolcus genus such as the samurai wasp, but U.S. native wasps have demonstrated low success of BMSB …

Lots of problems on unit-disk graphs have been considered in the literature, such as shortest paths, clique, independent set, distance oracle, diameter, etc. Specifically, we study the following problems in this dissertation: L₁ shortest paths in unit-disk graphs, reverse shortest paths in unit-disk graphs, minimum bottleneck moving spanning …

Desert Body, Lauren Mckinnon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis is a collection of poems examining certain paradoxes of my body. As a survivor of sexual violence, my body relives trauma which makes it feel uninhabitable. I compare my experiences with the Southern Utah desert. The physical beauty, destruction and inhabitability of the desert teaches me to accept my body as both beautiful and full of grief. The poems move chronologically through my life, beginning with an abusive relationship at the age of sixteen, a move to Moab at nineteen, and becoming a mother at twenty-five. Ultimately, with the desert as my guide, I learn to accept my …

High Efficiency Angles-Only Space-Based Approaches For Geosynchronous Orbit Catalog Maintenance With Sparse Information, Louis M. Tonc

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The thesis of this dissertation proposes a novel filter algorithm to improve tracking and catalog maintenance of uncooperative satellites and other Resident Space Objects (RSOs) in Geosynchronous Equatorial Orbit (GEO). Tracking can be supported by space-based tracking from observer satellites (OBSs). Practical limitations can lead to long time gaps between measurement updates when tracking RSOs from an OBS, which may induce a loss of fidelity or divergence of the estimation algorithm. The Extended Kalman filter (EKF) is commonly used for tracking RSOs but it diverges as a consequence of nonlinearity in the dynamics and nonlinearity in the optical measurements from …

Investigating The Effect Of Greediness On The Coordinate Exchange Algorithm For Generating Optimal Experimental Designs, William Thomas Gullion

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Design of Experiments (DoE) is the field of statistics concerned with helping researchers maximize the amount of information they gain from their experiments. Recently, researchers have been turning to optimal experimental designs instead of classical/catalog experimental designs. One of the most popular algorithms used today to generate optimal designs is the Coordinate Exchange (CEXCH) Algorithm. CEXCH is known to be a greedy algorithm, which means it tends to favor immediate, locally best designs instead of globally optimal designs. Previous research demonstrated that this tradeoff was efficacious in that it reduced the cost of a single run of CEXCH and allowed …

Use Of Protective Lactic Acid Bacteria Adjunct Cultures To Decrease The Incidence Of Gas Defects In Cheddar Cheese, Rhees T. Crompton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Gas production in cheese making is becoming increasingly prevalent in the dairy industry. This gas is produced by microbes that are naturally found in the cheese, and when they metabolize sugar or other sources of energy, they can produce gas. This gas causes slits and cracks in the cheese, which causes the cheese to be worth less and causes issues during slicing and shredding. There are many microbes that cause unwanted gas in cheese, this research focuses on four know gas producers and five other protective microbes that use the same energy sources or have the ability to inhibit the …

Relationships Between School, Teacher, And Feature Characteristics And Teachers’ Access To Features Within Digital Curriculum Resources For Mathematics Instruction, M. Jill Harmon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In 2019, RAND Corporation asked teachers which digital materials they used. This study expanded on this research by exploring the features contained in these programs. The purpose of this study was to investigate the relationships between teachers’ access to features and school (e.g., grand band, socioeconomic status), teacher (e.g., experience), and feature characteristics (e.g., feature choice). I report a significant regression model to predict the likelihood for a teacher to have access to each of the six features within differing contexts based on the characteristics.

To answer the research questions, I first reported descriptive statistics as percentages of teachers who …

The Gender Of Greek Suicide: Constructions Of Humor And Heroism In Epigrams, Acacia Grace Oyler

Classical Studies Honors Theses

In this thesis, I explore how epigram authors evoke and manipulate gendered modes of dying in their portrayals of suicide. More specifically, I examine how the sword/noose, male/female paradigm underlies their constructions of heroic and humorous suicides. Ultimately, I argue that the epigrams use gender-transgressive modes of self-killing to create their heroic and humorous suicide. This argument not only illuminates how epigrams played with a popular theme from ‘high’ literature but also the very telling ways that suicide was gendered in the Greek imagination.

Felicissima Matrum: The Construction Of Maternal Identity In Ovid's Metamorphoses And Fasti, Savannah Rose Wahlgren

Classical Studies Honors Theses

After finally gaining control of Rome as princeps, Augustus was tasked with both ushering in a new era of peace and a new imperial form of government. To contrast the masculine world of war that he sought to leave behind, Augustus turned his attention to mothers and used them in imperial ideology and imagery as symbols of prosperity and morality. This was supported through his moral legislation, which brought tangible, legal benefits to motherhood in addition to the benefits of status that were more loosely and implicitly defined. The transition to monarchy also brought attention to mothers as the importance …

Exploring The Effects Of Microarchitecture On Astrocyte Behavior And Vascular Remodeling In Spinal Cord Injury, Devin Gerber

Biomedical Engineering Undergraduate Honors Theses

Spinal cord injury (SCI) is a common condition and is characterized by traumatic and progressive damage that results in limited neuron regeneration and thus a restricted recovery. In SCI, the vasculature is also severely damaged, which exacerbates inflammation at the injury site. Specifically, insufficient angiogenesis occurs at the site of injury due to the fibrotic pathological microenvironment1 . SCI also leads to the formation of a fluid-filled cavity and thus gliosis and fibrosis, forming a dense glial and fibrotic scar around the cavity. The microenvironment at the injury site plays a significant role in astrocyte behavior, promoting the transformation of …

A Review Of Econometric Approaches For The Oil Price-Exchange Rate Nexus: Lessons For Asean-5 Countries, Khalid M. Kisswani, Mahelet G. Fikru

Economics Faculty Research & Creative Works

This paper reviews alternative econometric approaches the literature has used to examine the connectedness between oil prices and exchange rates and illustrates their application using quarterly data from 1970: Q1 to 2022: Q1 for ASEAN-5 countries, which are as follows: Indonesia, Malaysia, the Philippines, Singapore, and Thailand. Although most studies examining the impact of oil prices and exchange rates apply the Ordinary Least Squares (OLS) approach with symmetry, the quantile regression (QR) method is shown to offer a thorough investigation of the connectedness. For ASEAN-5 countries, we present a comparative analysis of both methodologies (OLS and QR) with and without …

Microbiome Recovery Of The Upper Clark Fork River Restoration Site, Danella Stapley

Graduate Theses & Non-Theses

Soil microorganisms provide ecosystem functions and services critical for life, can have lasting effects on aboveground plant communities, and can serve as indicators of soil quality. However, biotic indicators are underrepresented in soil health assessments. Incorporating microbial soil evaluations in ecological restoration studies are important in order to obtain a more comprehensive understanding about their role in healthy soil development. In this study, we used three bioindicators to assess the post-restoration soil microbiome recovery of the Upper Clark Fork River: extracellular soil enzyme activity, microbial biomass, and microbiome community and diversity. We found that microbiome recovery rate varied at different …
