Behavior Of Copper Oxide Nanoparticles In Soil Pore Waters As Influenced By Soil Characteristics, Bacteria, And Wheat Roots, Joshua Hortin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The goal of this project was to study the behavior of copper oxide nanoparticles in soil environments. Copper oxide nanoparticles have antimicrobial properties and may also be used in agricultural settings to provide a source of copper for plant health, but accidental or misapplication of these nanoparticles to soil may be damaging to the plant and its associated bacteria.

Dissolved soil organic matter that is present in soil pore waters dissolved nanoparticles, but did not dissolve the expected amounts from a geochemical model because the geochemical model did not take into account surface chemistry or coating of the nanoparticles by …

From Eden To Dystopia: An Ecocritical Examination Of Emergent Mythologies In Early Los Angeles Literary Texts, Jaquelin Pelzer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In From Eden to Dystopia: An Ecocritical Examination of Emergent Mythologies in Early Los Angeles Literary Texts, ecocriticism and critical regionalism were utilized alongside other American Studies practices to analyze nineteenth- and early-twentieth-century depictions of nature in Los Angeles. Specifically, these tools were applied to travel guides and narratives of the 1870s and 1880s, the turn-of-the-century magazine The Land of Sunshine, Upton Sinclair’s Oil! (1926) and Raymond Chandler’s The Big Sleep (1939), and other non-fiction publications of the 1920s and ’30s to track an evolving narrative of Los Angeles as a paradise and later as a place perched …

Land Use Dynamics And Implications For Water Management In The Urbanizing Wasatch Range Metropolitan Area Of Utah, Enjie Li

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Utah is one of the fastest growing states in the USA. Utah’s Wasatch Range Metropolitan Area (WRMA), where 80% of Utah’s population resides, is growing at unprecedented rates and has seen extensive urban landscape transformation in the last half century. Many of Utah’s agricultural lands, grasslands, and wetlands have been transformed into urban areas during this time. Local residents have watched and experienced these changes to their local environment, but without a clear understanding of the processes and impacts of urbanization. It is not until we study these landscapes from a spatial perspective and the time scale of decades that …

Acculturation And Language Use In Intimate And Sexual Relationships Among Chinese Bilinguals, Tianyi Xie

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

People of Chinese heritage often face complex challenges because of the conflicting values from China and America, especially on sexuality. Through two thousand years of socialization, Chinese culture grew to endorse conservative sexual values and gender roles. In traditional Chinese culture, women are expected to remain chaste and play submissive roles in marriage. Sexuality is treated as a taboo topic that should not be discussed directly. Asian American youth who endorse less traditional Chinese values experience lower sexual satisfaction, lower confidence in their own abilities, and higher adherence to traditional gender roles. Language has also been found to potentially influence …

Market Learning After Recurrent Meat And Poultry Recalls, Briana Thomas

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Several studies have been conducted to evaluate the cost of meat and poultry product recalls to food firms. The goal of this analysis is to formally test whether or not subsequent recalls are associated with less negative stock price returns, and whether or not there is a difference in the magnitude of returns between a first, second, and third or more recall. This is completed through an event study analysis. Results indicate that recurring recall events affecting a firm within 12 months of the first recall incident are indeed associated with less impactful negative outcomes. On average, initial recall events …

Heritable Sperm Chromatin Epigenetics: A Break To Remember, Ralph G. Meyer, Chelsea C. Ketchum, Mirella L. Meyer-Ficca

UAES Publications

Sperm chromatin not only has a unique structure to condense and protect the paternal DNA in transit, but also provides epigenetic information that supports embryonic development. Most of the unique sperm nuclear architecture is formed during the sweeping postmeiotic chromatin remodeling events in spermiogenesis, where the majority of nucleosomes are removed and replaced by protamines. The remaining histones and other chromatin proteins are located in structurally and transcriptionally relevant positions in the genome and carry diverse post-translational modifications relevant to the control of embryonic gene expression. How such postmeiotic chromatin-based programming of sperm epigenetic information proceeds, and how susceptible the …

Optimizing Barrier Removal To Restore Connectivity In Utah’S Weber Basin, Maggi Kraft

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

River barriers, such as dams, culverts and diversions are important for water conveyance, but disrupt river ecosystems and hydrologic processes. River barrier removal is increasingly used to restore and improve river habitat and connectivity. Most past barrier removal projects prioritized individual barriers using score-and-rank techniques, neglecting the spatial structure and cumulative change from multiple barrier removals. Similarly, most water demand models satisfy human water uses or, only prioritize aquatic habitat, failing to include both human and environmental water use benefits. In this study, a dual objective optimization model identified in-stream barriers that impede quality-weighted aquatic habitat connectivity for Bonneville cutthroat …

Urban Bobcat (Lynx Rufus) Ecology In The Dallas-Fort Worth, Texas Metroplex, Julie M. Golla

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Urban landscapes are quickly replacing native habitat around the world. As wildlife and people increasingly overlap in their shared space and resources, so does the potential for human-wildlife conflict, especially with predators. Bobcats (Lynx rufus) are a top predator in several urban areas across the United States and a potential contributor to human-carnivore conflicts. This study evaluated the movements and habitat use of bobcats in the Dallas-Fort Worth (DFW), Texas metroplex. Spatial data were collected from 10 bobcats via Global Positioning Satellite (GPS) for approximately one year. Average home range size was 4.60 km² (n=9, SE=0.99 km …

Rancher Perceptions Of Ecosystem Services From Rangelands Of The Intermountain West, Elisabeth C. York

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Rangelands within the Great Basin are responsible for the provision of multiple resources that humans depend on for a variety of reasons. Ranchers in this region are dependent on public lands to remain economically viable in their cattle operations. As a majority of land in this region is publically owned, there are varying interests at play in what should and could be the focus of management. Ranchers are charged with implementing strategies aimed at conserving these landscapes and their motivations for what to manage may significantly influence resource provision from Intermountain West ecosystem.

In this study, I sought to understand …

Non-Methane Hydrocarbon Source Apportionment And Btex Risk Assessment Of Winter 2015 In Roosevelt, Utah, Jerimiah Lamb

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Non-Methane Hydrocarbons (NMHC) monitored in Roosevelt Utah including Benzene, Toluene, Ethylbenzene and Xylene (collectively known as BTEX) are associated with deleterious effects including cancer. This study was designed to assess the origin and effect of the toxicants and addressed two points: 1) Source identification using the USEPA’s Positive Matrix Factorization (PMF) and NOAA’s Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model and 2) A human health risk assessment based on ambient concentrations of BTEX collected at the Roosevelt site. Model fit indicated that the primary contributor to total NMHCs was local oil and gas operations and was supported by previous …

The Marriage and Family Therapy clinic at Utah State University conducted a study called the Relationship Checkup in which couple data was collected in an initial 2-hour session and feedback was provided for them in a follow-up 1-hour session. This checkup included completing self-report surveys, having an in-person interview, as well as couple interactions. The current study was carried out within the context of this broader relationship checkup, focusing on the couple support interactions, in which partners discussed a personal issue they would like to change about themselves.

Although a substantial amount of attention has been given to the role …

Toxicity And Mitochondrial Delivery Of Flavonol-Based Carbon Monoxide-Releasing Molecules, Hector Jose Esquer Heredia

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Despite the reputation of carbon monoxide (CO) as a silent killer, new evidence suggests that this gaseous molecule has anti-inflammatory, anti-cancer and vasoprotective properties. Unfortunately, little is known about the role of CO in the body. However, proteins present in mitochondria are believed to be important targets. We previously synthesized a class of novel and structurally modifiable flavonol-based CO-releasing molecules (CORMs). Flavonols are commonly found in fruits and vegetables. The base structure, Flav-1, is fluorescent, exhibits low toxicity, and releases CO after exposure to visible light. Previous reports indicate that addition of a triphenylphosphonium (TPP) tail allows chemical structures to …

Genetic Differentiation Of Two Species Of Buckwheat (Eriogonum), Jenessa Blotter Lemon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Limestone mining in the San Franicso Mountain Range of west central Utah threatens the survival of a rare endemic species of buckwheat (Eriogonum soredium). This species is an edaphic endemic, only found growing on the outcrops of the Ordovician limestone mines in the area. Eriogonum soredium is a candidate for governmental protection under the Endangered Species Act (ESA). However, a common, widespread buckwheat (Eriogonum shockleyi) appears to be closely related to the narrow endemic. The genetic relatedness of the rare and and common species will greatly influence the decision of United States Fish and Wildlife Service …

Allowing The Untellable To Visit: Investigating Digital Folklore, Ptsd And Stigma, Geneva Harline

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the introduction of 2012 issue of The Journal of Folklore Research, Diane Goldstein and Amy Shuman issue a “call to arms for folklorists … to concentrate on the vernacular experience of the stigmatized.” (Goldstein and Shuman, 2012:116). Drawing on this call to arms, this thesis investigates how Post-Traumatic Stress Disorder (PTSD) is portrayed in social media through memes and captioned images. I argue that the genres of memes and captioned images in digital folklore work to help mitigate the stigma of PTSD because the veneer of anonymity in the digital world allows people with PTSD to be willing …

Stream Temperature Monitoring And Modeling To Inform Restoration: A Study Of Thermal Variability In The Western Us, Jessica R. Wood

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Water temperature is an important variable for aquatic ecosystems. Salmonid population numbers and distribution are heavily influenced by stream temperature, and there is growing concern about the health of salmonid populations with anticipated climate change. Managers are looking to efficiently evaluate options to maintain stream temperatures needed by salmonids. This study evaluated and compared stream temperature restoration alternatives in two streams with warm temperatures using stream temperature monitoring and modeling.

The first study identified pockets of cold water that are important to native fish species in Nevada’s Walker River. Comparison of monitoring results with existing basin-scale model outputs identified two …

Ecology Of Greater Sage-Grouse Inhabiting The Southern Portion Of The Rich-Morgan-Summit Sage-Grouse Management Area, M. Brandon Flack

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Greater sage-grouse (Centrocercus urophasianus; sage-grouse) are sagebrush obligates and are therefore considered to be key indicators of sagebrush ecosystem health. Sage-grouse populations have declined range-wide over the last century due to loss and fragmentation of sagebrush (Artemisia spp.) habitats. Sage-grouse populations found in large intact sagebrush landscapes are considered to be more resilient, however, some small isolated populations persist and thrive in fragmented landscapes. Because of Utah’s unique topography and geography, sage-grouse habitat is discontinuous and populations are naturally dispersed throughout the state in suitable intact blocks or in disconnected islands of sagebrush habitat. Thus, Utah populations …

Regulation And Energy Poverty In The United States, Michael C. Jensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Energy poverty is a topic often neglected in the discussion about global climate change. Apocalyptic prophecies about the negative future effects of climate change ignore the suffering of people around the globe whose lives could be drastically improved with access to reliable sources of energy. Though energy poverty from a global perspective is much more serious than energy poverty from a domestic perspective, high home energy bills are a serious cause for concern for many Americans.

This research examines the relationship between regulation, the prices of electricity and natural gas, and the household energy burden, which is the ratio of …

Lactational Performance And Energy Partitioning Of Dairy Cows Supplemented With N-Acetyl-L-Methionine During Mid To Late Lactation, Tyson George Grisenti

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The N-acetyl-L-methionine (NALM) molecule is a methionine (Met) derivative produced via acetylation of the L-Met α-amino group with an N-acetyl group. This molecule has been shown to be bioavailable and capable of fulfilling the dietary requirement for Met in animals and humans. The current experiment was conducted to test a hypothesis that lactating dairy cows fed with NALM would increase milk production by increasing N and energy utilization efficiencies in a dose dependent manner. Eight multiparous Holstein cows that were mid lactation (124 ± 13 days-in-milk) with similar milk production were used in a 4 x …

Measurement Of Agriculture-Related Air Pollutant Emissions Using Point And Remote Sensors, Kori D. Moore

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Measuring air pollution emissions from agricultural activities is usually difficult because of their large area and variability. Traditional air quality sensors, called point samplers, measure conditions in one location, which may not adequately measure a plume. Remote sensors, instruments that measure pollution along a line rather than at a single point, are better able to measure conditions around large areas. This dissertation reports on four agricultural air emissions studies that used both point and remote sensors for comparison. The methods used to calculate the emissions are based on previous work and are further developed in these studies. In particular, an …

Community Wildfire Planning And Design: A Review And Evaluation Of Current Policies And Practices In The Western United States, Carlene C. Klein

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wildland fire is an important and complex issue, particularly in the fire-prone ecosystems of the Western United States. At the same time that the number of catastrophic wildland fires is increasing across the United States, more people are moving in to wildland areas growing the interface between urban and wildlands. Managing wildfire in the Western United States is becoming increasingly more complex and costly as growth and development continues to push the edge of municipalities into undeveloped wildlands. Communities in this wildland urban interface are exacerbating the problem of wildfire in the West.

With more people living in wildfire prone …

Exploring The Effect Of Disability Microaggressions On Sense Of Belonging And Participation In College Classrooms, Lynsie Harris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Microaggressions are a form of interpersonal discrimination towards marginalized groups that are often ambiguous in nature and delivered unintentionally. The subtleness of these attacks on identity can make them difficult to recognize and address.

Emerging research reveals that the targets of microaggressions are experiencing negative effects on their wellbeing; however, the bulk of existing literature on this topic only addresses microaggressions perpetrated towards racial minority or LGBT individuals. Little is known about pervasiveness and potential impact of microaggressions directed towards people with disabilities- particularly in academic contexts.

This study pilots a measurement tool, the Microaggressions Towards Students with a Disability …

Contributors To Wisconsin’S Persistent Black-White Gap In Life Expectancy, Max T. Roberts

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For decades, blacks have faced shorter life expectancy than their white counterparts. This persistent disparity has led to a gap in life expectancy between the two groups. Nationally, this gap has decreased over the last 40 years. However, this is not the case at the state-level as some states have experienced little or no improvement in the life expectancy gap. Such is the case in Wisconsin, where the life expectancy gap is the largest in the nation for males, and the gap actually has grown for females over the last two decades. This study seeks to examine this persistent gap …

Development Of An Animal Model For Enterovirus For Evaluation D68 For Screening Of Antiviral Therapies, W. Joseph Evans

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Enterovirus D68 (EV-D68) virus has become more prevalent over the last 15 to 20 years. EV-D68 attacks the respiratory system and can cause severe disease in individuals who have underlying respiratory problems. There have also been reports of individuals with EV-D68 showing signs of neurological system problems and acute flaccid paralysis. Because of the increase in patients with EV-D68 and also the potential for neurological disease, an animal model is needed to study the disease and to evaluate experimental therapies for EV-D68 infection.

To develop the animal model, 4-week old AG129 mice that lack alpha and beta interferon receptors, making …
