A Survey Of College Students With Learning Disabilities And Attention Deficit Hyperactivity Disorder To Identify Their Relationship And Use Of College Disability Resource Centers, Telia M. West

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

College students with learning disabilities (LD) and/or attention deficit hyperactivity disorder (ADHD) complete college at lower rates than their non-disabled peers (Newman & Madaus, 2015). Colleges receiving federal funding are required to have a disability resource center (DRC) that provides and coordinates accommodations for students with disabilities. This project examined the factors that led students with LD and/or ADHD to initially contact their college DRC. This project examined data from 61 college students pursuing an undergraduate degree with LD and/or ADHD who had already contacted their DRC. A survey was sent to those students asking about circumstances surrounding their …

As you teach students this information, the compelling question to have students focus on is: “Does culture and the interaction of cultures shape the development of place?” Each event highlighted on this website is related to the other and demonstrates how …

Licentious Legends: A Folklore Podcast, Alexandra L. Haynes

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

Licentious Legends was created out of a need to both understand and educate about sexual contemporary legends; not just what they are and what defines them, but the effect that they have on those who experience them. The purpose of this podcast is not to shame, but to take what has been found and educate about the joys and dangers of these legends. These legends range from the everyday (such as "The Hook"), to legends about a young man killing himself with a plunger. In an effort to gather as many examples as they could, Faye interviewed several of their …

Using Tree-Ring Growth And Stable Isotopes To Explore Ponderosa Pine Ecophysiological Responses To Climate Variability And The 2012-2015 California Drought, Rachel M. Keen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Climate warming in recent decades has resulted in more frequent and severe drought events in the western United States. These changes are projected to continue, making it exceedingly important to understand how forests respond to severe drought stress, and how we can manage these forests to reduce mortality during future events. The 2012-2015 California drought is a recent example of a severe, multi-year drought that was coupled with an epidemic-scale outbreak of western pine beetle, killing nearly 90% of ponderosa pines in the central and southern Sierra Nevadas. In the first portion of this study, we compared pairs of surviving …

For instance, penicillin as an early-discovered antimicrobial agent has saved millions of lives, indicating the …

Adapting Environmental Ethics And Behaviors: Toward A Posthuman Rhetoric Of Community Engagement, Beth J. Shirley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

What persuades people one way or another to accept or deny climate change? More importantly, what persuades people to act on, ignore, or even be defiant of climate change? We would like to think that people are motivated when they hear the science explained clearly and when they are presented with a clear understanding of how their actions have a lasting impact. Yet the science on climate change has been made clear for some time, and doubt in climate change science is rampant (at least in the United States).

This dissertation seeks to answer these questions and develop a new …

Linkage Of Climate Diagnostics In Predictions For Crop Production: Cold Impacts In Taiwan And Thailand, Parichart Promchote

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This research presents three case studies of low temperature anomalies that occurred during the winter–spring seasons and their influence on extreme events and crop production. We investigate causes and effects of each climate event and developed prediction methods for crops based on the climate diagnostic information. The first study diagnosed the driven environmental-factors, including climate pattern, climate change, soils moisture, and sea level height, associated with the 2011 great flood in Thailand and resulting total crop loss. The second study investigated climate circulation and indices that contributed to wet-and-cold (WC) events leading to significant crop damage in Taiwan. We developed …

Eared Grebe Nesting Ecology And Chronology Along The Great Salt Lake, Utah, Leah M. Delahoussaye

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Eared Grebes (Podiceps nigricollis) are migratory birds that build their nests over water and in large groups called colonies. Their typical breeding range is in central southern Canada and northern United States; however, a previously uncertain number of Eared Grebes (grebes) also nest around the Great Salt Lake (GSL), Utah, at the southern edge of their breeding range. Little is known about the habitat requirements for grebe nesting colonies at such low latitudes and if they are different from colonies found elsewhere. My objectives for this research were to determine the status of the grebe nesting population as …

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 …

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 …

Investigation Of The Molecular Determinants And Extrinsic Factors That Regulate Prmt Product Specificity, Tamar B. Cáceres

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Protein arginine methylation is an important modification of proteins, involved in many cellular processes. Some examples are transcription, RNA editing, cellular communication, DNA repair, viral replication and chromatin remodeling. In recent years, the significance of protein arginine methyltransferases (PRMTs) in human diseases has been increasingly studied, especially in cardiovascular disease and cancer. Although the importance of these enzymes is recognized, the understanding of how exactly PRMTs function is still limited. Very little information is available to explain how or why any of the different PRMTs interact with other proteins or, what determines where in that protein to place their methyl …

Effect Of Supplemental Prebiotics, Probiotics And Bioactive Proteins On The Microbiome Composition And Gut Physiology In C57bl6/J Mice, Ye Li

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The composition and metabolic activity of the microbiome affect many aspects of health, and there is current interest in dietary constituents that may affect this system. The purpose of this study was to evaluate the effects of a mix of probiotics, a mix of prebiotics and a bioactive protein fraction on the microbiome, when fed to mice individually and in combination. Mice were fed the total western diet (TWD) supplemented with prebiotics, probiotics, and Tri-Factor (bioactive proteins) individually and in combination for four weeks. Subsequently, effects on the composition of gut microbiome, gut short chain fatty acids (SCFAs) concentration, gut …

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 …

Resurgence Of Cocaine-Seeking In Rats Following Long Access And Punishment, Rusty W. Nall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Strategies that provide access to alternative non-drug rewards are among the most effective at reducing substance use in individuals with substance use disorders, but relapse often occurs when alternative rewards are removed. Relapse induced by the loss of alternative rewards is called resurgence, and represents a challenge to otherwise effective strategies for reducing drug use. An animal model has been useful for studying resurgence, but the extant model has two limitations. First, humans usually refer to the negative consequences of drug use as the reason they stop taking drugs, but the extant model uses drug unavailability to reduce drug seeking. …

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 …

Nest-Site Selection Of Golden Eagles And Ferruginous Hawks And Diet Composition Of Sensitive Raptor Species Using Metabarcoding Analysis In The Uinta Basin And Ashley National Forest, Ut, Usa, Dylan J. Hopkins

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Development and climate change in the sagebrush habitats are causing population declines of North American hawks and eagles. For these species, understanding the landscape features that are preferred for nesting and the prey they consume in sagebrush habitats are important in developing conservation plans. Specifically, we know little of the preferred nest-sites and diet of Ferruginous Hawks (Buteo regalis) and Golden Eagles (Aquila chrysaetos) many locales. In our study, we determined the landscape characteristics associated with nest sites for these two raptor species in the Uintah Basin, UT to predict where nests may occur in our …

The Vulnerability Of Littoral Structures Under Multiyear Drought Conditions, Jenna M. Keeton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Climate change is associated with altered environmental conditions and shifting mosaics of suitable habitats for organisms. Climate change in the form of drought can shift important lake shoreline habitats downslope, altering the lakes chemistry and habitat availability. Additionally, negative biological consequences can occur after a loss of submerged habitat along shorelines, hereafter littoral habitat. The objective of this study is to evaluate whether littoral habitat is lost (cobble, coarse woody habitat (fallen trees; CWH), and aquatic vegetation) under drought conditions across the United States. I used the National Lakes Assessment physical habitat data collected in summer 2012, when 75% of …

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 …

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 …

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 …
