Pickleball For Inactive Mid-Life And Older Adults In Rural Utah: A Feasibility Study, Paige Wray, Callahan K. Ward, Cindy Nelson, Sandra H. Sulzer, Christopher J. Dakin, Brennan J. Thompson, Matthew Vierimaa, Debasree Das Gupta, David A. E. Bolton

Extension Research

Many diseases, disabilities, and mental health conditions associated with aging can be delayed or prevented through regular exercise. Several barriers to exercise, many of which are exacerbated in rural communities, prevent mid-life and older adults from accessing its benefits. However, recently, a racquet sport named pickleball has become popular among older adults, and it appears to overcome some of these barriers. We conducted a feasibility study to evaluate the impact of a six-week pickleball intervention on measures of muscle function, cognitive function, perceived pain, and cardio-metabolic risk, as well as several psychosocial factors contributing to adherence in sedentary rural participants. …

Smartsat Constellation - A Deep Reinforcement Learning Approach For Decentralized Coordination, Rajesh Aggarwal, Junghwan Kim, Deepanshu Agarwal, Ayushi Tiwari, James Baldo

Small Satellite Conference

With rapid advancements in satellite technology, the amount of low earth orbit satellites has grown significantly which are primarily deployed for weather monitoring, earth observation or military purposes. Due to this reason, there has been an increased interest in enhancing the level of autonomy and cognition, onboard satellites to achieve optimal data collection. Optimal data is said to be collected when the satellites in a small sat constellation work together to collect information. This means that even if one of the satellites has missed out on some important information, the others can still collect them. A satellite constellation can be …

Human Appropriation Of Net Primary Production: From A Planet To A Pixel, Suman Paudel, Gustavo A. Ovando-Montejo, Christopher L. Lant

UAES Publications

Human appropriation of net primary production (HANPP) is a substantial improvement upon 20th century attempts at developing an ecological footprint indicator because of its measurability in relation to net primary production, its close relationship to other key footprint measures, such as carbon and water, and its spatial specificity. This paper explores HANPP across four geographical scales: through literature review, the planet; through reanalysis of existing data, variations among the world’s countries; and through novel analyses, U.S. counties and the 30 m pixel scale for one U.S. county. Results show that HANPP informs different sustainability narratives at different scales. At the …

The Impact Of A Spill Or Pollution Accident On Firm Environmental Activity: An Empirical Investigation, Rick Hardcopf, Rachna Shah, Suvrat Dhanorkar

Management Faculty Publications

Spill and pollution (SP) accidents cause significant damage to the natural environment. They also result in financial costs and reputational losses for the offending firm. As such, understanding how firms respond to such crises is of significant interest to firm stakeholders, such as investors, customers, regulators, NGOs, employees, and local communities. In this study, we examine whether publicly disclosed SP accidents cause firms to alter their approach to environmental management, as expressed by the adoption of environmental management practices (EMPs). Using a unique panel data from 2002 to 2013, representing over 400 publicly-traded US manufacturing firms, we find that in …

Understanding Climate Change Impacts And Adaptation Potentials At Utah Ski Resorts, Rachel Hager

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

Increasing temperature and shifting precipitation regimes due to climate change are a significant threat to winter recreation. Some businesses such as high-elevation ski resorts are especially vulnerable to the impacts of climate change. However, ski resorts may be able mitigate the impacts of climate change by proactively implementing adaptation strategies. The overall goal of this study was to investigate the impact of climate change on Utah ski resorts, and to understand adaptation perception, barriers, and strategies for different resorts across the state.

To meet that goal, we used a mixed-methods approach including examining temperature shifts at all Utah ski resorts …

Risk Factors For Early And Late Onset Depression And Subsequent Risk For Alzheimer's Disease And Related Dementias In An Older Adult Population, Jordan Kugler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Cache County Study on Memory in Aging (CCSMA) was a research study that followed 5092 participants aged 65 or older over the course of 12 years, examining risk and protective factors for dementia. One of these factors was depression history, which has evidence for a connection with dementia, such that those with a history of depression are more likely to develop dementia later in life. However, the existing literature has yet to examine sex differences, genetic and psychosocial factors that contribute to earlier or later onset of depression and how these factors in turn might later increase risk for …

Saudadades Da Minha Terra Amada: Brazilian Immigrants In Utah, Corinne Clarkson-Heaps

Undergraduate Honors Capstone Projects

“We are all strangers in a strange land, longing for home, but not quite knowing what or where home is,” author Madeleine L’engle once wrote (L’engle 1993). The Portuguese language has a word for this feeling - saudade. Saudade is hard to describe in English, but it is often described as a feeling of longing, or nostalgia that is supposedly characteristic of the Brazilian temperament. Brazilian immigrants are familiar with this feeling. Though generally grateful for new opportunities, they often describe the saudades that they have for their terra amada, or “beloved homeland,” after coming to America. Saudades …

Iluqata: All Of Us, Cana Uluak Itchuaqiyaq

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The field of technical and professional communication (TPC) is solidly within the social justice turn that encourages TPC practitioners and scholars to consider how their work, if left unchecked, could perpetuate oppressive societal norms, such as racism. Increasing awareness of how technical communicators can combat oppression through coalitional action and through centering multiply marginalized and underrepresented (MMU) voices and experiences through inclusive research methodologies are important components towards equity in TPC. This dissertation presents five accepted publications that demonstrate how narrative methodologies and coalitional work function to enhance scholarly activism and work towards equity. These five publications are thoroughly introduced …

Characterizing Pinyon Jay Nest Habitat At Multiple Spatial Scales, Elizabeth Audrey Moore

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

Land management practices in piñon-juniper woodlands can impact piñon pine (Pinus edulis, Pinus monophylla) obligates, including the pinyon jay (Gymnorhinus cyanocephalus). I summarized covariates surrounding pinyon jay nests to characterize pinyon jay nesting habitat at multiple scales relevant to both restoration work and pinyon jay life history. By referencing my results and overlaying my predictive models with proposed project sites, land managers can incorporate habitat metrics important to jays into restoration planning.

The Utah Division of Wildlife collaborated with Colorado Parks and Wildlife and the U.S. Fish and Wildlife Service to study pinyon jay occupancy in …

A Mixed-Methods Approach To Explore Student Perceived Needs For Peer Mentorship In A College Of Engineering, Darcie Christensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

“Nobody makes it alone. Nobody has made it alone” (NOVA SHRM & Dulles SHRM, 2012, p. 5). Mentoring generally has positive outcomes, such as increasing output, staying in work or school, increasing confidence, and others (Campbell & Campbell, 2007; Crisp & Cruz, 2009; Eby et al., 2008; NASEM, 2019; Pfund et al., 2016). This dissertation study focused on student perceived needs for peer mentorship in engineering, which can fill in gaps of traditional mentorship by pairing mentors and mentees at similar levels, increasing comfort and emotional support to mentees (Allen et al., 2017; Haggard et al., 2011; Kram & Isabella, …

Don't Get Me Started About The Water: Foodways And Power In Juvenal's Satire V, Alex Reese

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Don’t Get Me Started About the Water analyzes the food in the dinner of Juvenal’s fifth satire from the perspective of Roman foodways in the first and second centuries. This analysis provides a surprising conclusion: although the guest and host are served dishes differing vastly in quality, neither man gets a nutritious meal. This follows with arguments elsewhere in the Satires, namely that Rome itself kills its occupants and the best course of action is to abandon the city for the countryside.

No Evidence Of Stochastic Resonance In Postural Sway Response To Noisy Galvanic Vestibular Stimulation In Healthy Young Adults, Dominique Rice

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

The transcutaneous application of a sub-sensory electrical stimulation to the vestibular afferents, known as noisy galvanic vestibular stimulation (nGVS), is thought to cause a reduction in postural sway at optimal amplitude intensities due to a mechanism known as stochastic resonance (SR). SR is a phenomenon whereby the addition of low amplitude noise to a non-linear system can be beneficial rather than detrimental. In humans, behavioral markers of SR in postural sway have been inconsistent, potentially due to insufficient power or false positives. Therefore, the main purpose of this study was to determine whether the frequency of observing SR-like effects improves …

Logbert: Log Anomaly Detection Via Bert, Haixuan Guo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

When systems break down, administrators usually check the produced logs to diagnose the failures. Nowadays, systems grow larger and more complicated. It is labor-intensive to manually detect abnormal behaviors in logs. Therefore, it is necessary to develop an automated anomaly detection on system logs. Automated anomaly detection not only identifies malicious patterns promptly but also requires no prior domain knowledge. Many existing log anomaly detection approaches apply natural language models such as Recurrent Neural Network (RNN) to log analysis since both are based on sequential data. The proposed model, LogBERT, a BERT-based neural network, can capture the contextual information in …

Gender And Political Incentives: Examining The Applicant Pool Under Merit Selection, Logan M. Loftis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Merit selection is a judicial selection system for when a state’s constitution or statute directs an independent nominating commission to evaluate applicants as a precursor to gubernatorial appointment. The initial process to fill a judicial vacancy under merit selection has three steps: application, nomination, and appointment. Proponents of the selection system insist that by de-emphasizing politics and highlighting qualifications, judicial diversification will be more likely to increase under merit selection. Yet, there is not a clear consensus as to whether merit selection systematically engenders a more diverse bench.

In this thesis, I explore whether women are less likely to apply …

Disinfection results in in the formation of haloamines from the unintended reactions of human and animal inputs and bromide/chloride with oxidants and disinfectants which cause health problems.

The purpose of this research was to examine the occurrence of haloamines during the chlorination of saltwaters. In this study, the effect of bromide concentration was observed to exert a significant effect on the stability of Haloamines, and with no bromide …

The Rhetoric Of The Double-Voiced: Strategic Ambiguity In The Silent Protest Parade, Shelby R. Crow

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Examinations of historical social movements offer great insight into contemporary social justice activism. In this thesis, I analyzed the Silent Protest Parade of 1917. The Silent Protest Parade consisted of approximately 10,000 African American men, women, and children who marched in complete silence to illuminate racial violence and the lynchings of African Americans. I argued that through the concept of strategic ambiguity, protesters were able to communicate between African American and powerful White audiences, many of whom held racist beliefs and attitudes.

When Healthy Turns Harmful: Increasing Understanding Of Potential Risk Factors And Approaches To Decreasing Orthorexic Behaviors, Elizabeth King

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Orthorexia Nervosa (ON) is a relatively new term used to describe individuals who place an excessive value on consuming a “pure” or healthful diet, so much so that their psychological, and potentially physical, health is negatively affected. ON is driven by a focus of consuming high-quality foods rather than limiting the quantity of food. This has sometimes been referred to as “clean eating”, or only consuming “clean” foods. A commonality between ON and other eating disorders (EDs) is that the behaviors are rooted in restriction, where an individual with ON would focus on restricting specific foods, or even entire food …

Susceptibility Of High-Elevation Forests To Mountain Pine Beetle (Dendroctonus Ponderosae Hopkins) Under Climate Change, David N. Soderberg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Across western North America, pine forests are important for timber, wildlife habitat, and at high elevations are important for water retention and yield from rain and snowmelt. The mountain pine beetle (MPB) is one of the most significant disturbance agents shaping pine forests, and like all insects, temperature is a major driver of its population success and the dynamics of the landscapes that they inhabit. Changing temperature regimes can therefore directly influence MPB population persistence at a particular location, in addition to potential shifts in the range boundaries that they inhabit. MPB is currently expanding its range northward in British …

Investigating The Habits Of Mind Of Practicing Engineers, Theresa K. Green

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One goal of undergraduate engineering education is to prepare students with the knowledge, skills, and decision-making strategies that are necessary for success in engineering practice. One proposed method to teach students these skills is to incorporate habits of mind into K-12 and undergraduate curricula. Habits of mind are the intelligent, social behaviors that engineers should aspire to have when solving problems, engaging with others, and dealing with uncertainty. Previous literature has suggested that incorporating ideas about habits of mind in educational curricula can teach students the disciplinary skills, technical knowledge, and social values that would help prepare them to enter …

Cultural Memory And Media: Spanish Republicans And The Spanish Civil War, Stuart Cameron

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This project examines the interplay between memory, history, and politics relating to Spanish Republican memories of the Spanish Civil War (1936-1939) and the following authoritarian dictatorship of Francisco Franco (1939-1975). In my analysis of this relationship, I focus on the years around the passage of the Law of Historical Memory in 2007; I explore how Spaniards used several forms of media, namely books, graphic narratives, and interviews, to relay their messages regarding the recovery, preservation, and passage of the memories of the defeated Republicans. The authors in each medium, despite telling different stories, both real and fictional, portrayed the act …

Community And Cultural Reentry: Exploring Reverse Culture Shock Among Returning Missionaries Of The Church Of Jesus Christ Of Latter-Day Saints, Sydney Pond

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Considerable research asserts that individuals who have immersive experiences in foreign cultures may experience mental and emotional challenges upon returning home, a phenomenon known as reverse culture shock. The Church of Jesus Christ of Latter-day Saints annually sends tens of thousands of proselytizing missionaries to various locations around the globe, and the nature of their missionary service places them at risk of experiencing problems during reentry. Despite this risk, reverse culture shock among returning Latter-day Saint missionaries remains relatively unexplored. The aim of this study was to examine how former Latter-day Saint missionaries made sense of their experiences returning to …

Computational Techniques For Elucidating Plant-Pathogen Interactions: A Case Study On Citrus-Hlb Interactome, Cristian D. Loaiza

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Citrus fruit industry in the United States has been affected during the last two decades because of the outbreak of the citrus greening disease, also known as Huanglongbing (HLB). Many people and organizations are working in therapeutics to help mitigate the impact of this disease, unfortunately there is not a cure yet. There are many mechanisms that needs to be understood about this disease, especially at the molecular level. Not only HLB, but many other infectious diseases are controlled by the interaction of proteins from the host (Citrus in this case) and from the pathogen that causes the disease. …
