The second component of this thesis will consist of the first four chapters of my memoir, with the remaining chapters to be completed post-graduation. These chapters take place the years before my parents’ deportation and the year immediately after. The memoir is a coming-of-age story that explores my ethnic identity, along with themes such as insider versus outsider. This …

Genetic Mapping Of Grass Monoculture And Grass-Legume Mixture Compatibility Qtls In Intermediate Wheatgrass, John Mortenson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Due to increased environmental stewardship and fertilizer prices, there is increased interest in using legume mixes in perennial croplands. The objective of this study was to compare quantitative genetic parameters and quantitative trait loci (QTLs) associated with intermediate wheatgrass (Thinopyrum intermedium) when grown in 1) a non-competitive spaced environment, 2) a polyculture with alfalfa (Medicago sativa), and 3) a monoculture with crested wheatgrass (Agropyron desertorum). Traits evaluated include plant growth characteristics (Zadok’s maturity, height, and tiller count), biomass, and forage nutritive value (CP, NDF, ADF, ADL, IVTD, NDFD, NFC, ME, RFQ). A linkage map …

Optimization Of Biogas Production By Use Of A Microbially Enhanced Inoculum, Anna Doloman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A renewable energy source, biogas, comprises of methane (80%) and carbon dioxide (15%), and is a great alternative to the conventional fossil-based fuels, such as coal, gas and oil. Biogas is created during anaerobic biological digestion of waste materials, such as landfill material, animal manure, wastewater, algal biomass, industrial organic waste etc. A biogas potential from organic waste in the United States is estimated at about 9 million tons per year and technology allows capture of greenhouse gases, such as methane and carbon dioxide, into a form of a fuel. In the light of global climate change and efforts to …

Teachers' Conceptions Of Mathematics And Intelligent Tutoring System Use, Andrew R. Glaze

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this mixed-methods study was to investigate the relationship between teachers’ conceptions of mathematics and their use of intelligent tutoring systems for mathematics instruction. Intelligent tutoring systems are adaptive computer programs which administer mathematics instruction to students based on their cognitive state. A conception is a mixture of beliefs and knowledge. The participants in this study were 93 junior high school mathematics teachers from three school districts in the Midwest. Data were gathered using a two-part online survey. The first part of the survey contained questions about their use of intelligent tutoring systems, graphing calculators, Desmos and dynamic …

Query Autoawesome, Chetna Suryavanshi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This research investigates how to improve legacy queries. Legacy queries are queries that programmers have coded and are used in applications. A database application typically has tens to hundreds of such queries. One way to improve legacy queries is to add new, interesting queries that are similar to or based on the set of queries. We propose Query AutoAwesome, a tool to generate new queries from legacy queries. The Query AutoAwesome philosophy is taken from Google’s AutoAwesomizer tool for photos, which automatically improves a photo uploaded to Google by animating the photo or adding special effects. In a similar …

Urban Alaskan Moose: An Analysis Of Factors Associated With Moose-Vehicle Collisions, Lucian R. Mcdonald

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As human populations continue to grow and encroach into wildlife habitats, instances of human-wildlife conflict are on the rise. Increasing numbers of reported wildlife-vehicle collisions (WVCs) provide tangible evidence of anthropogenic impacts on wildlife as well as increasing threats to human health and safety. Increasing WVCs are of particular concern, especially those involving large-bodied ungulates such as moose (Alces spp.), because of the increased risk of property damage, personal injuries, and human fatalities. Motorists directly involved in a WVC are at risk of injury or mortality, but other motorists are also put at risk due to road obstructions and traffic …

Ecosystem Functioning Of Great Salt Lake Wetlands, Maya Cassidy Pendleton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Great Salt Lake (GSL) wetlands account for ~75% of all Utah wetlands and provide not only critical habitat for millions of migratory birds, but also provide valuable ecosystem functions and services as well as economic benefits to Utahns. However, these wetlands are facing an aggressive invader, Phragmites australis, that has spreading across the GSL wetlands and replacing native wetland habitats. Wetland managers have spent countless resources and time trying to control the spread of P. australis and restore GSL wetlands. However, we do not fully understand how these wetlands functions and services are being altered with this habitat …

Dementia Caregiver Coping Strategies And Caregiver-Care Recipient Relationship Closeness: Associations With Care-Recipient Outcomes, Stephanie Behrensberg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This project used data from the Dementia Progression Study, a longitudinal, population-based study based out of Cache County, Utah. Statistical models were used to examine the association between caregiver factors, the care environment, and cognitive outcomes in persons with dementia. Mediational analyses were also used to examine if the care environment, inferred for nutritional status, engagement in physical and cognitively stimulating activities, mediated the relationship between the closeness/caregiver coping strategies and cognition in persons with dementia. Results showed that closer caregiver-care recipient relationships were associated with better nutritional status and more engagement in number of cognitively stimulating activities as well …

Development And Validation Of An Agricultural Literacy Instrument Using The National Agricultural Literacy Outcomes, M. Rose Judd-Murray

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was conducted to develop a standardized agricultural literacy assessment using the National Agricultural Literacy Outcomes (NALOs) as benchmarks. The need for such an assessment was born out of previous research, which found that despite numerous programs dedicated to improving agricultural literacy, many students and adults remain at low or very low levels of literacy. Low literacy levels lead to negative associations with the production and processing of food, clothing, and shelter, as well as misinformed public perceptions and policies. Agricultural literacy researchers recognized that the development of a standardized assessment for post-12^th grade, or equivalent, could unify …

Thylacine Dreams: The Vernacular Resurrection Of An Extinct Marsupial, Daisy M. Ahlstone

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis explores the folk resurrection of the thylacine through artwork and symbolic interaction. The thylacine, better known as the Tasmanian tiger, is a marsupial that suffered a government-sanctioned massacre leading to its extinction in 1936. The thylacine’s status as a hidden animal has inspired what folklorists call “ostensive practice”; people not only actively seek out the thylacine in the wilderness of Tasmania today and share their sightings online, but they have also incorporated the thylacine as a symbol of hope and perseverance into various forms of folk art.

There have been upwards of five thousand documented sightings of the …

The Thermal And Physical Properties Of Beef From Three Usda-Quality Grades Cooked To Multiple Degrees Of Doneness, Jessica Mcclellan Hadfield

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The objective of this study was to determine the influence of quality grade (QG) and degree-of-doneness (DOD) on thermophysical properties of beef strip steaks. The “Prime” eating experience must be marketed to compete with cheaper protein sources, and so palatability is a major concern with beef products. Thermal and physical properties help shed light on the impacts various components have on beef palatability, mainly tenderness and juiciness. Warner-Bratzler shear force (WBSF) and the textural property of springiness are both influenced by a combination of QG and DOD. This is also true for viscoelasticity and the degradation of myosin and sarcoplasmic …

Epigenetic Reprogramming, Apoptosis, And Developmental Competence In Cloned Embryos, Laura A. Moley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Cloning through somatic cell nuclear transfer (SCNT) remains highly inefficient twenty years after the first demonstration of the technology with the birth of Dolly. By increasing efficiency by selecting the embryos early in development that are most likely to succeed following transfer into a surrogate mother, the technology could be more routinely utilized to enhance animal agriculture production. SCNT is believed to be highly inefficient as a result of incorrect DNA methylation and gene expression that are accumulated because of the SCNT technique. We proposed the use of a non-toxic, non-invasive detector of cell death, to quantitatively assess embryo competency …

The Effect Of Lactation And Energy Status On Gene Expression In The Main Reproductive Tissues Of Lactating Dairy Cattle, Sameer M. Alhojaily

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Modern high-yielding dairy cows are currently producing far more milk than their ancestors due to a prolonged and intensive genetic selection for milk production trait accompanied by the revolutionary improvement in technology, management, and nutrition. On the other hand, a noticeable decline in fertility and reproductive performance was undeniably consistent with the increase in milk yield. This decline in fertility and reproductive performance are recognized worldwide and well documented in several studies. Dairy cows typically experience a period of energy deficit during the first few months of lactation due to the rapid increase in milk production and limited feed intake. …

Subsistence Strategy Tradeoffs In Long-Term Population Stability Over The Past 6,000 Years, Darcy A. Bird

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

I conduct the first comparative analysis of long term human population stability in North America. Questions regarding population stability among animals and plants are fundamental to population ecology, yet no anthropological research has addressed human population stability. This is an important knowledge gap, because a species’ population stability can have implications for its risk of extinction and for the stability of the ecological community in which it lives. I use archaeological and paleoclimatological data to compare long term population stability with subsistence strategy and climate stability over 6,000 years. I conduct my analysis on a large scale to better understand …

A Narrative Approach To Educational Video Training, Matthew S. Havertz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Teachers often use videos to teach their students, but stories are not used as often in educational videos as they could be. Experts tell us that stories are an important part of teaching and learning. Unfortunately, there is only a small amount of research and no definitive expert agreement about stories used in educational videos. This is especially true for videos used with technical education students, like mechanic students or dental assisting students. In this study, dental assisting students learned how to assist a dentist with a standard cavity procedure after watching a video with or without a story. The …

"There Should Be No Tolerance For Intolerance": Internal Antagonism In Online Fan Communities, Michelle W. Jones

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis focuses on exploring cases of internal antagonism in fan communities, with a specific focus on the Steven Universe (2013 -) and Undertale (2015) communities present on Tumblr and Twitter. Internal antagonism is a phenomenon that occurs when a community targets a member within itself instead of outside itself, often as a way to mediate and regulate the community and reinforce its values. This thesis considers three case studies of internal antagonism with both physical and digital implications in order to better understand the role it plays in shaping and sustaining online fan communities as well as mediating the …

Women In Agriculture: Living In A "Man's World", Ennea A. Fairchild

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Despite women’s involvement in agriculture, their contributions have been overlooked in society. Women make up at least a third of those involved in agriculture as farmers, landowners, and in agricultural faculty positions. These numbers do not appear to be decreasing. Although there are several agricultural roles, this study focuses primarily on those women who own agricultural land, but do not farm the land themselves. Rather, these women rent it out to a farmer who operates the land for them (women nonoperating landowners or WNOLs, in short). Previous research suggests these women may be facing considerable barriers as an agricultural landowner …

The Factors Affecting Wind Erosion In Southern Utah, Mehmet Ozturk

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wind erosion is a global issue and affecting millions of people in drylands by causing environmental issues (acceleration of snow melting), public health concerns (respiratory diseases), and socioeconomic problems (costs of damages and cleaning public properties after dust storms). Disturbances in drylands can be irreversible, thus leading to natural disasters such as the 1930s Dust Bowl. With increasing attention on aeolian studies, many studies have been conducted using ground-based measurements or wind tunnel studies. Ground-based measurements are important for validating model predictions and testing the effect and interactions of different factors known to affect wind erosion. Here, a machine-learning model …

Biophysical And Structural Characterization Of Shigella Atpase Spa47 Oligomerization Provides Insight Into Type Three Secretion System Activation And Virulence, Jamie L. Burgess

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Several bacterial pathogens including Shigella (shigellosis), Escherichia coli (urinary tract infections), Pseudomonas (lung infections), Salmonella (food poisoning), and Yersinia (plague) critically rely on a complex type three secretion system (T3SS) for infection. With the rise in multi-antibiotic resistant strains of several of these pathogens, we turn to the T3SS as a promising target for the development of novel therapeutics. The Dickenson lab at Utah State University has been the first to identify and characterize the ATPase Spa47, the energy source of the Shigella infection system. We show that Spa47 is necessary for proper T3SS formation and function, being ultimately responsible …

Evaluating The Effectiveness Of Livestock Guardian Dogs: Loss-Prevention, Behavior, Space-Use, And Human Dimensions, Daniel Kinka

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Livestock guardian dogs – or “LGDs” – are commonly used by domestic sheep ranchers and reduce the need for killing wild carnivores to protect livestock. LGDs are mostly used in the United States to reduce the number of livestock killed by coyotes, but whether they can prevent killing by larger carnivores like wolves and grizzly bears is unclear. It is important to identify which behavioral traits and LGD breeds work best for guarding livestock so that ranchers can protect their stock and environmentalists can enjoy a greater number of wild animals on the landscape. This study investigated the effectiveness of …

A Csra-Binding, Trans-Acting Srna Of Coxiella Burnetii Is Necessary For Optimal Intracellular Growth And Vacuole Formation During Early Infection Of Host Cells, Shaun Wachter, Matteo Bonazzi,, Kyle Shifflett, Abraham Moses, Rahul Raghavan, Michael F. Minnick

Biology Faculty Publications and Presentations

Coxiella burnetii is an obligate intracellular gammaproteobacterium and zoonotic agent of Q fever. We previously identified 15 small non-coding RNAs (sRNAs) of C. burnetii. One of them, CbsR12 (Coxiella b urnetii small RNA 12), is highly transcribed during axenic growth and becomes more prominent during infection of cultured mammalian cells. Secondary structure predictions of CbsR12 revealed four putative CsrA-binding sites in stem loops with consensus AGGA/ANGGA motifs. We subsequently determined that CbsR12 binds to recombinant C. burnetii CsrA-2, but not CsrA-1, proteins in vitro. Moreover, through a combination of in vitro and cell …

Development Of Novel Zika And Anthrax Viral Nanoparticle Vaccines, Elizabeth Henderson

KGI Theses and Dissertations

Vaccines protect against numerous infectious diseases and prevent millions of deaths annually, but there are still many infectious diseases for which no licensed vaccine exists. Developing a new vaccine requires balancing safety and efficacy, and viral nanoparticle (VNP) vaccines possess both of these characteristics. The work herein demonstrates how tobacco mosaic virus (TMV) nanoparticles can serve as a platform to create candidate vaccines for Zika virus (ZIKV) and anthrax. In the first study, a ZIKV-specific epitope was genetically fused to TMV to create a safe and inexpensive vaccine that proved highly immunogenic in mice and led to the discovery of …

The Saga Of The Jómsvikings: A Translation For Students, Alison Finlay, Þórdís Edda Jóhannesdóttir

Northern Medieval World

Unique among the Icelandic sagas, part-history, part-fiction, the Saga of the Jómsvikings tells of a legendary band of vikings, originally Danish, who established an island fortress of the Baltic coast and launched and ultimately lost their heroic attack on the pagan ruler of Norway in the late tenth century. The saga's account of their stringent warrior code, fatalistic adherence to their own reckless vows and declarations of extreme courage as they face execution articulates a remarkable account of what it meant to be a viking. This translation presents the longest and earliest text of the saga, never before published in …

Iraq: A Photo Essay, Sean Sutton

The Journal of Conventional Weapons Destruction

MAG, Mines Advisory Group, has worked in Iraq since 1992 to make land safe for populations affected by decades of conflict. Landmines, cluster munitions, other unexploded bombs, as well as new contamination from the recent conflict with ISIS, have left a deadly legacy that prevents communities from using their land, and displaced populations from returning home safely.
