Analyzing The Von Neumann Entropy Of Contact Networks, Thomas J. Brower

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

When modeling the spread of disease, ecologists use ecological or contact networks to model how species interact with their environment and one another. The structure of these networks can vary widely depending on the study, where the nodes of a network can be defined as individuals, groups, or locations among other things. With this wide range of definition and with the difficulty of collecting samples, it is difficult to capture every factor of every population. Thus ecologists are limited to creating smaller networks that both fit their budget as well as what is reasonable within the population of interest. With …

Enhancing The Production And Sustainability Of Pasture-Fed Beef Using Non-Traditional Legume Forages, Andrea I. Bolletta

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Despite the increasing worldwide demand for beef as a protein source, consumers are concerned about the sustainability of ruminant production systems. Their main concerns are animal welfare for feedlot-fed animals, greenhouse gas (GHG) emissions, global warming and worker safety. Traditional feedlot-based beef production systems have been associated with locally greater levels of soil, water and air contamination, as well as the overuse of antibiotics and growth hormones. The use of legume pastures such as cicer milkvetch (CMV) and birdsfoot trefoil (BFT), which fix their own nitrogen (N) and often contain beneficial secondary compounds such as tannins and provide for rapid …

Investigating Nest Box Utilization By Bumble Bees And Reproductive Development Of Male Bumble Bees, James Daniel Herndon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bumble bees (Bombus Latrielle) are a wide-spread group of pollinating insects that are important species to conserve across many environments to ensure both ecological and economic resiliency because they pollinate important agricultural, horticultural, and wild flora. Surprisingly, fundamental questions still remain about this important charismatic group of pollinators. The investigations in this thesis are but two of many topics that require further research. The topics investigated are understanding bumble bee nest site preferences and reproductive development of both sexes of bumble bees. The first experiment (Chapter 2) investigates whether nest boxes elevated off of the ground and attached to …

The Effects Of Milk Phospholipids On Functional Properties Of Anhydrous Milk Fat And Oil Structured Gel Systems, Zachary Cooper

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Lecithin is an ingredient commonly used in foods composed of high concentration of phospholipids. Phospholipids are a type of fat that can mix with both water and oil. In the current food industry, most lecithins come from sunflower, egg, and soybean sources. An additional source of phospholipids can be the waste streams from the dairy industry, such as the whey protein and butter making processes, since these contain a high concentration of phospholipids. Dairy phospholipids have been isolated in the past, but their traits as a functional ingredient are still unknown. In addition, most isolated dairy phospholipids still contain protein, …

Development Of A High-Resolution Land Cover Dataset To Support Integrated Water Resources Planning And Management In Northern Utah, Ellie Irene Leydsman Mcginty

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Integrated planning and management approaches, including bioregional planning and integrated water resources planning, are comprehensive strategies that strive to balance the sustainability of natural resources and the integrity of ecosystem processes with human development and activities. Implementation of integrated plans and programs remains complicated. However, geospatial technologies, such as geographic information systems and remote sensing, can significantly enhance planning and management processes.

Through a United States Environmental Protection Agency Region 8 Wetland Program Development Grant, a high-resolution land cover dataset, with a primary emphasis on mapping and quantifying impervious surfaces, was developed for three watershed sub-basins in northern Utah - …

Exploring The Connection Between Acid Exposure And Virulence In Listeria Monocytogenes, Minghao Li

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Listeria monocytogenes is a gram-positive food-borne pathogen that is widely dispersed in the environment and can cause listeriosis with high fatality rates when consumed in contaminated food products. They are capable of growing over a wide range condition. Listeria is also able to tolerate adverse conditions which allows the bacterium to survive in unfavorable environments. The ubiquitous nature of L. monocytogenes makes it difficult to eliminate from food systems. One major problem in the food industry is the survival of L. monocytogenes under sublethal low pH-environment since organic acids are widely used as food decontaminants. Prior research has suggested that …

The study used a collective case study design in order to better understand what espoused and enacted pedagogical …

Methods In Modeling Wildlife Disease From Model Selection To Parameterization With Multi-Scale Data, Ian Mcgahan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effects of emerging wildlife diseases are global and profound, resulting in loss of human life, economic and agricultural impacts, declines in wildlife populations, and ecological disturbance. The spread of wildlife diseases can be viewed as the result of two simultaneous processes: spatial spread of wildlife populations and disease spread through a population. For many diseases these processes happen at different timescales, which is reflected in available data. These data come in two flavors: high-frequency, high-resolution telemetry data (e.g. GPS collar) and low-frequency, low-resolution presence-absence disease data. The multi-scale nature of these data makes analysis of such systems challenging. Mathematical …

Try The Wine: Food As An Expression Of Cultural Identity In Roman Britain, Molly Reininger

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research surrounding cultural identity and food customs throughout history are published often, but any research that attempts to combine the two are often based in more recent history. Few combinations of the two are available, and fewer explore the implications within ancient colonization and expansion.

The research for this thesis was conducted with three viewpoints in mind: the colonization of Britannia from Romans within the new colony, the colonization from the native Briton's perspective, and the Roman citizens within Britannia at the end of Rome's military involvement with the colony. This method was chosen because in the early years of …

Automating And Analyzing Whole-Farm Carbon Models, Aditi Maheshwari

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The goal of this research is to learn about whole farm carbon models. A whole farm carbon model estimates the emissions of greenhouse gasses (GHGs) based on information for a farm. We analyzed two models, HOLOS whole-farm and COMET-Farm, by running the models on random inputs and building classifiers from the runs. HOLOS estimates GHG emissions for a particular year based on crop and animal agriculture input, while COMET-farm adds past and future farm management practices. Users of the models must manually enter farm data through a graphical user interface (GUI), which is a good method for a single farm, …

Harmful Algal Blooms: Dominance In Lakes And Risk For Cyanotoxin Exposure In Food Crops, Austin D. Bartos

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Climate change and human activities are promoting the dominance of a photosynthetic family of aquatic bacteria, cyanobacteria. Blooms of cyanobacteria are not only a visual nuisance but can produce a variety of cyanotoxins than can harm the liver, skin, and nervous system of animals and humans. We analyzed lakes in the contiguous United States and found that between 2007 and 2012, the number of lakes that produced measurable quantities of cyanotoxins increased from 33% to 45%. Nitrogen and phosphorus pollution were the main drivers of cyanobacteria blooms and toxin production between these years. Many of these lakes and reservoirs are …

Teaching Appropriate Feedback Reception Skills Using Computer-Based Training, Seth G. Walker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Feedback is a commonly used intervention to address performance issues in a number of settings. Most research on feedback has focused on manipulating parameters surrounding the delivery of feedback. However, the interaction between those delivering the feedback and a feedback recipient may also influence the impact of performance feedback. The current study investigated the efficacy of training individuals to receive feedback in an appropriate manner using a computer-based training format. Following computer-based training, participants exhibited increases in accuracy of appropriate feedback behaviors when compared to baseline. Participants also demonstrated slight increases in performance on primary job tasks. This study extends …

Harvest Efficiency Of Forage Grazed By Cattle And The Effect Of Pinyon And Juniper Treatments On Vegetation Cover On The Grand Staircase Escalante National Monument, Ruger P. Carter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Grand Staircase Escalante National Monument (GSENM), located in central south Utah, currently has 76,957 active grazing animal unit months on the monument. Recently, there has been questions whether the harvest and grazing efficiency coefficients developed in the Midwest are applicable to the arid, bunch grass dominated systems of the GSENM. Harvest and grazing efficiency defines the percentage of allocated forage that is being ingested by the animal, and the percentage that is being wasted. Harvest and grazing efficiency coefficients were calculated on the Lower Cattle allotment on the GSENM by taking total forage production and dividing that by expected …

Development And Identification Of Metrics To Predict The Impact Of Dimension Reduction Techniques On Classical Machine Learning Algorithms For Still Highway Images, Wasim Akram Khan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

We are witnessing an influx of data - images, texts, video, etc. Their high dimensionality and large volume make it challenging to apply machine learning to obtain actionable insight. This thesis explores several aspects pertaining to dimensional reduction: dimension reduction methods, metrics to measure distortion, image preprocessing, etc. Faster training and inference time on reduced data and smaller models which can be deployed on commodity hardware are a critical advantage of dimension reduction. For this study, classical machine learning methods were explored owing to their solid mathematical foundation and interpretability.

The dataset used is a time series of images from …

Cultural Ecosystem Services Of Agroecosystems Along The Wasatch Front, Utah, Tiffany K. Woods

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Agroecosystems, including peri-urban systems, are important providers of a range of services. However, management of these systems has generally been based on the market value of crops, neglecting to capture the broader public goods that ecosystem services provide to stakeholders. While the ecosystem service framework (Millennium Ecosystem Assessment [MEA], 2005) has been adopted to measure the market and non-market values associated with these services, knowledge gaps persist, particularly with respect to the quantification and valuation of cultural ecosystem services (CES). In this paper, the determination of CES values assigned to agroecosystems by residents of two communities along the Wasatch Front, …

Harmonic Delay Reduction, Jay E. Hinnenkamp

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Stimuli which, during the life of an organism, acquire the ability to increase the probability of behavior that they follow are called conditioned reinforcers. The concurrent-chains procedure has been used to study conditioned reinforcement for over 60 years. During this time several different models have been developed to explain how stimuli become conditioned reinforcers. The three experiments of this dissertation introduced a new quantitative model of conditioned reinforcement (DRT_H) and tested its predictions against four existing models. The results of Experiment 1 indicated that DRT_H improves upon the accuracy of its predecessor, delay reduction theory (Fantino, 1969), …

Ecoacoustic Methods For Multi-Taxa Animal Surveys In The Amazon, Leandro A. Do Nascimento

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Tropical regions host most of the biodiversity found on Earth, but these species-rich areas are constantly threatened by human development and other disturbances that put this diversity of life forms at risk. To avoid extirpations of animal and plant species, scientists and managers rely on accurate monitoring techniques to retrieve information about population trends. This task is not easy, especially in the tropics, where there is often a lack of personnel to conduct surveys, a lack of funding, and the areas are so extensive that many countries need to be involved in monitoring (e.g., Amazon biome). For this reason, scientists …

Regenerating Unfinished Buildings, I Troiani, A Dawson

School of Art, Design and Architecture

A result of untethered building booms, fuelled by neoliberal policy and/or the false conception of construction being an economic vehicle in its own right, unfinished buildings, often represents a greater stigma of failure to their communities than do buildings that have fallen redundant. Semi-constructed and then abandoned buildings became a significant urban reality in countries like Greece, Spain and Italy in the wake of the 2008 financial crisis, littering the urban environment with wasted materials. The typical concrete frame structures are also opportune templates for a multitude of formal and informal additions and the basis for a type of architectural …

Long-Term Incarceration And The Moral Limits Of Punishment, Jacob Bronsther

Cardozo Law Review

Hundreds of thousands of Americans are serving decades-long prison sentences. While scholars have established that these sentences are both economically inefficient and destructive of minority communities, a fundamental question remains: Is long-term incarceration ever morally permissible? Understandably, the economists and sociologists of prison have not addressed this moral question. But neither have the philosophers of criminal law, who rarely consider sentencing issues. This Article seeks to fill this lacuna. It does so by reviving the moral and legal prohibition on degrading punishment. The Article argues that long-term incarceration is impermissibly degrading, on a par with the death penalty and penal …

Marketing To The New Generations Of Lgbtq+ Tourists, George Smith

Master's Theses

As social acceptance for LGBTQ+ people grows, it is essential to research and understand more about tourism and its important role in the lives of LGBTQ+ populations. There are tourism communities around the country that may not be familiar with this market segment and are not sure where to start. This can leave the LGBTQ+ market segment under-represented in the tourism industry. This research sets out to answer the question, “Can tourism communities who wish to expand to newer generations of LGBTQ+ travelers market to them successfully?” Mixed research methods include an exploration of city tourism websites, interviews with tourism …

The New Left In American Evangelicalism, Jonathan E. Harris

Masters Theses

In the late 1960s and early 1970s a new kind of evangelical emerged as a result of interaction with New Left ideas. The evangelical left gained strength until the mid 1970s, only to reemerge in the 2010s.

Giant Calcified Left Circumflex Coronary Artery Aneurysm With Complex Coronary-To–Left Ventricular Communication, Rabih Touma, Mohan Palla, Khurshaid Alam, James F. Mastromatteo, Aiden Abidov

Diagnostic Radiology Articles

A 64-year-old asymptomatic man had an incidental finding of a giant left circumflex artery (LCX) aneurysm, with the distal LCX draining into a confluence receiving terminal portions of all coronary arteries and communicating with the left ventricle through a transmural fistulous tract. We believe that this is the first case reported with such a complex LCX abnormality.

Activation Of Trpa1 Nociceptor Promotes Systemic Adult Mammalian Skin Regeneration, Jenny J. Wei, Hali S. Kim, Casey A. Spencer, Donna Brennan-Crispi, Ying Zheng, Nicolette M. Johnson, Misha Rosenbach, Christopher Miller, Denis H. Y. Leung, George Cotsarelis, Thomas H. Leung

Research Collection School Of Economics

Adult mammalian wounds, with rare exception, heal with fibrotic scars that severely disrupt tissue architecture and function. Regenerative medicine seeks methods to avoid scar formation and restore the original tissue structures. We show in three adult mouse models that pharmacologic activation of the nociceptor TRPA1 on cutaneous sensory neurons reduces scar formation and can also promote tissue regeneration. Local activation of TRPA1 induces tissue regeneration on distant untreated areas of injury, demonstrating a systemic effect. Activated TRPA1 stimulates local production of interleukin-23 (IL-23) by dermal dendritic cells, leading to activation of circulating dermal IL-17–producing γδ T cells. Genetic ablation of …

Playing On The Threshold: Topological Chronotopes And Video Games, Michael Joseph Piero

English Theses & Dissertations

This study argues that the chronotope—literally “timespace”—is a useful, flexible heuristic for understanding how video game timespace is ideology, often encoding hegemonic norms of heteronormativity, misogyny, sovereign power’s control of bare life, and dualistic thinking. Adapting and reforging Mikhail Bakhtin’s “chronotope of the threshold,” I track the topological movements of threshold chronotopes across a series of games and game genres that reveal threshold experiences of play, ontology, and justice. This work of theory takes into account video game mechanics, interfaces, narratives, iconography, and materiality within the context of a player’s experience as a player-reader given to a bodily-rooted play with …

Deep Learning For Remote Sensing Image Processing, Yan Lu

Computational Modeling & Simulation Engineering Theses & Dissertations

Remote sensing images have many applications such as ground object detection, environmental change monitoring, urban growth monitoring and natural disaster damage assessment. As of 2019, there were roughly 700 satellites listing “earth observation” as their primary application. Both spatial and temporal resolutions of satellite images have improved consistently in recent years and provided opportunities in resolving fine details on the Earth's surface. In the past decade, deep learning techniques have revolutionized many applications in the field of computer vision but have not fully been explored in remote sensing image processing. In this dissertation, several state-of-the-art deep learning models have been …
