The Effect Of An American Heart Association–Approved Exercise Regimen On Burnout In Nurse Practitioners And Physician Assistants Working In Emergency Departments, Michelle Lee Johnson

Electronic Theses and Dissertations

Burnout is a widely known state of physical and emotional fatigue previously noted to affect as many as 60% of healthcare providers, but one that is understudied in nurse practitioners and physician assistants working in emergency departments. It is imperative that the providers of healthcare recognize in themselves signs of burnout and have resources available to mitigate the condition. A pretest–posttest, quasi-experimental, nonequivalent control group, descriptive research design with descriptive statistics analysis was used to analyze answers to an email-based survey sent to nurse practitioners and physician assistants working for one large emergency medicine staffing company. The intent of this …

Mindfulness Based Stress Reduction Techniques In Chronic Illness, Anna Celia Gil

Electronic Theses and Dissertations

Abstract

Chronic stress and its effect on both physical and mental health have been a topic of increasing interest in the past several decades. There is mounting evidence that recurrent, persistent stress of both a physiologic and psychological nature leads to a dysfunction in the hypothalamic pituitary axis (HPA), the system which helps the body recover and adapt to short term stress. In long term stress, this HPA dysfunction leads to impairment of the immune and neuroendocrine systems resulting in chronic low-grade inflammation. This type of chronic inflammation acts as a precursor to several chronic illnesses such as diabetes, hypertension, …

Ceo, Cfo, And Audit Partner Gender, And Accounting Conservatism, Ceara Hintz

Electronic Theses and Dissertations

I examine the association between CEO, CFO, and audit partner gender and accounting conservatism using a unique sample that encompasses hand-collected data. While accounting conservatism reflects less risky accounting choices, risk aversion theory indicates that females are more risk averse than males. I apply risk aversion theory to accounting conservatism and investigate two research questions: (i) Does the CEO or CFO and audit partner gender influence accounting conservatism? (ii) Does a female audit partner influence the relationship between a male CEO or CFO and accounting conservatism? Using skewness as a proxy of accounting conservatism, I test three hypotheses. The results …

Free Trade Is Not Free: A Case For Fair Trade, Wardah Javaid Cheema

Electronic Theses and Dissertations

To this day, mainstream economists favor free trade policies as the best way to generate economic development. They do so at the expense of their unjustified romanticization of reductionist classical trade theories. This thesis seeks to comprehend the constraints of traditional trade theories and their inability to be applied to practical contemporary problems. Further, contrary to the fundamental assumption of free trade theory, there is ample evidence of government intervention in free trade agreements. These interventions solely encourage and protect large corporations and investors rather than the actual development and sustainability factors, namely labor and the environment. It all adds …

Examination Of Formal Instructional Design Processes At Traditional Institutions Of Higher Education In The United States Post-Pandemic Onset, Heather L. D. Tobin

Electronic Theses and Dissertations

The purpose of this study is to identify the motivational elements of formal online instructional design processes that are being implemented at traditional institutions of higher education (IHEs) in the United States (U.S.). For this study, I conducted a comprehensive literature review identifying emerging issues of practice for instructional design partnerships between the onset of the COVID-19 pandemic during the spring of 2022 and the spring of 2023. This study was developed through the lens of Keller’s (2010) attention, relevance, confidence, satisfaction, and volition (ARCS-V) model of motivation. An understanding of the elements of current processes that present as benefits …

Til Valhall: The Formation Of Nordic Neopagan Identity, Religiosity, And Community At A Norwegian Heavy Metal Festival, Padraic M. Fitzgerald

Electronic Theses and Dissertations

A major draw of Nordic Neopaganism is the great degree of personal freedom practitioners have in the construction and performance of their spiritual identity. Nordic Neopaganism has no central hierarchy or unifying dogmatic system to dictate such endeavors. Instead, practitioners draw from the tradition’s body of “lore” -- the historical accounts, archaeological records, pre-Christian myths, folklore, and folk traditions from the Nordic cultural area -- to inform their religiosity. The works of visual artists, musicians, and scholar-practitioners inspired by elements of this body of lore serve to further constitute it. This lore provides the basis and inspiration for religious identity …

Power System Dynamic Control And Performance Improvement Based On Reinforcement Learning, Wei Gao

Electronic Theses and Dissertations

This dissertation investigates the feasibility and effectiveness of using Reinforcement Learning (RL) techniques for power system dynamic control, particularly voltage and frequency control. The conventional control strategies used in power systems are complex and time-consuming due to the complicated high-order nonlinearities of the system. RL, which is a type of neural network-based technique, has shown promise in solving these complex problems by fitting any nonlinear system with the proper network structure.

The proposed RL algorithm, called Guided Surrogate Gradient-based Evolution Strategy (GSES) determines the weights of the policy (which generates the action for our control reference signal) without back-propagation process …

Queer Is Here, Hopefully To Stay: The Incorporation And Reception Of Lgbtq+ History At The History Colorado Center, Madeline Ohaus

Electronic Theses and Dissertations

Historically, the documentation of LGBTQ+ histories, struggles, and accomplishments has been absent from museum collections and exhibitions. Scholars argue that given the authoritative nature of museums and their influence on the public, exclusions of LGBTQ+ history can mount to institutional erasure of queer identities. However, in the past decade, there has been an increase in attempts to document and curate exhibitions highlighting and encouraging the public to engage with LGBTQ+ history. While this history is imperative to preserve and display, it can be met with controversy, leading some LGBTQ+ history exhibitions to be relocated or even removed. During the summer …

Mechanistic Insights Into Mftr-Dependent Regulation Of The Redox Cofactor Mycofactocin, Aigera Mendauletova

Electronic Theses and Dissertations

Organic redox cofactors are essential for life. While classic flavins and nicotinamides are widely distributed across all domains of life, nature has also evolved niche cofactors in subsets of life domains. For example, in Actinobacteria, coenzyme F420 is commonly used in place of flavin mononucleotide in enzymes associated with carbon fixation and oxidation of secondary alcohols. The importance of niche cofactors has long been recognized however, detailed understanding about their biosynthesis and physiological uses has been lagging. One class of niche cofactors is derived from ribosomally synthesized and posttranslationally modified peptides (RiPPs). To achieve their mature form, the genetically …

'They Were Known Accordingly’: The Journey Of The Land Otter Pole And Memorial Pole At The Denver Art Museum, Penske Stranger Mccormack

Electronic Theses and Dissertations

In 2019, two Kaigani Haida (Alaskan Haida) totem poles (Xaadas Gyáa’ang) were re-raised in the renovated Northwest Coast gallery of the Denver Art Museum. Lee Wallace and his family, descendants of Haida carver Dwight Wallace and Dwight’s son John Wallace, led a ceremony that publicly acknowledged the Wallace family’s connection to the two poles, reintroduced Haida cultural protocols into their care and viewing, and set the stage for future collaborations between the museum and family. This study explores the history of the poles and the intersecting forces that shaped their journey from Sukkwan, Alaska, to Denver, including shifting ideals of …

Artificial Emotional Intelligence In Socially Assistive Robots, Hojjat Abdollahi

Electronic Theses and Dissertations

Artificial Emotional Intelligence (AEI) bridges the gap between humans and machines by demonstrating empathy and affection towards each other. This is achieved by evaluating the emotional state of human users, adapting the machine’s behavior to them, and hence giving an appropriate response to those emotions. AEI is part of a larger field of studies called Affective Computing. Affective computing is the integration of artificial intelligence, psychology, robotics, biometrics, and many more fields of study. The main component in AEI and affective computing is emotion, and how we can utilize emotion to create a more natural and productive relationship between humans …

A Study Of The Cultural And Geological Environment Of The Magic Mountain Site In Golden, Colorado, Brianna K. Dalessandro

Electronic Theses and Dissertations

The Magic Mountain site, located in Golden, Colorado, has been the subject of intensive academic studies since the 1950s because of its extensive artifact assemblage and long habitation periods. The aim of this thesis was to use ground-penetrating radar, magnetometry, GIS models, and lithic analysis to further study when and how the Magic Mountain site was used during prehistoric times and contextualize a variety of hypotheses about site habitation and migratory patterns of prehistoric people in Colorado.

The results of these analyses indicate the habitation and migratory pattern of the Magic Mountain site was a periodic, but consistent, proximal visitation …

Seeing The Unseen: Bridging Realities Of Experience Through Dependent Origination, Shubham Sapkota

Electronic Theses and Dissertations

Overall, this project looks into the problem and history of colonialism, the impact of it on the people and knowledge coming from South Asia, and offers an alternate view to understand our world. The notion of seeing the unseen acknowledges that there are facets of our day-to-day reality that we are often unaware of when thinking about our communities and ourselves. Yet, being able to fully acknowledge and understand the seen and unseen aspects of our community is necessary if we are to work towards improving our communities for the long run. By relying on the Buddhist teaching and discourse …

School District Demographic Change Through The Lens Of High School Students: A Phenomenological Case Study, Isaac S. Solano

Electronic Theses and Dissertations

Over the past two to three decades, inner-ring suburban school districts in certain areas around the United States have experienced significant demographic change. These shifts influence who lives in these communities, as well as who attends schools in these K–12 school districts. In a metropolitan area, in the Rocky Mountain West Region of the United States, numerous school districts are experiencing such shifts. Although past empirical research has examined shifts through the lens of school leaders and teachers, few studies have explored how students experience this change.

This qualitative hermeneutic phenomenological case study examines how high school students experience these …

Plant Community Response To Control Of A Dominant Invader At Multiple Scales, Alexander R. B. Goetz

Electronic Theses and Dissertations

Control of invasive Tamarix spp. in riparian systems has long been a priority for management in western North America, but questions remain regarding the response of the broader plant community to different treatments. Here we summarize a series of approaches at different scales to quantify the effects of Tamarix control on characteristics of this ecosystem, including provisioning of wildlife habitat. In the first chapter we analyzed findings of the last 20 years using meta-analysis and found that although treatment has been successful in reducing Tamarix and promoting native vegetation to some extent, most literature reports very small effect sizes and …

Interactions In The Mind: Examining Metacognition's Role In Entrepreneurial Performance, John Sebesta

Electronic Theses and Dissertations

To better understand the mental processes that shape entrepreneurial performance, this dissertation examines the moderating effect of metacognitive abilities on the relationship between cognitive style and entrepreneurial alertness on performance at the opportunity identification and planning stages of the entrepreneurial journey. Prior research identifies these factors as components of an entrepreneurial mindset. However, the present research develops and examines theoretically driven predictions regarding how the factors interact. Using a sample of seventy teams participating in a business plan competition enables performance evaluation at these early steps in the entrepreneurship process. The hypotheses were not supported, but post hoc analyses indicate …

Problems With Machine Learning, High-Dimensional Data And Forecasting Stock Returns, Erik Mekelburg

Electronic Theses and Dissertations

Using a multi-level ensemble design, we forecast international stock market returns with a novel high-dimensional data set of aggregated cross sectional firm-level predictors. The method includes considerations of model uncertainty, parameter instability, model density and non-linearities with machine learning, shrinkage and model averaging. We provide evidence that it is important to systematically focus on all four sources of forecast failure, shed light on the sparsity/density debate in the stock return forecasting dialogue and contribute interesting findings on the efficacy dimensionality reduction with principal components analysis and partial least squares. The robustness of the approach is demonstrated through applications in four …

Virtual Reality Influence On Moral Reasoning Through Compassion, Dennis W. Dunivan

Electronic Theses and Dissertations

This study investigates quantifiable links between virtual reality, moral reasoning, and compassion, contributing to the development of improved pedagogy for moral leadership development through experiential learning. It is the first empirical study to determine how specific virtual reality experiences potentially influence moral reasoning as measured by the DIT-2 (Rest et al., 1999), as well as the possible mediation effects of compassion on this relationship as measured by the Compassion Scale (Pommier et al., 2019). Although pedagogical implications are discussed, including the integration of virtual reality experiences into curriculum, the boundaries of this study are controlled to measure the direct influence …

“We’Re Dealing With An Inhumane Lack Of Resources”: Provider Perspectives On Palliative And End-Of-Life Care For Adults Experiencing Homelessness, M. Pilar Ingle

Electronic Theses and Dissertations

Although palliative and end-of-life (PEOL) care offer many benefits to individuals with life-limiting illness, unhoused individuals face barriers in accessing these forms of care. Despite calls over the last several decades to improve PEOL services for unhoused individuals, this population remains underprioritized in efforts to improve access to healthcare. A richer understanding of these inequities as they relate to the specific social and political contexts within a state, such as Colorado, may offer more direct guidance on opportunities to improve policy and care provision.

The purpose of this study was to explore healthcare and social service provider-identified approaches and challenges …

Sense Of Community And (Third) Place Among Young Adults In Permanent Supportive Housing: A Mixed-Methods Inquiry, Danielle Maude Littman

Electronic Theses and Dissertations

Unhoused young people have often endured co-occurring experiences of marginalization, including long-term abuse and neglect from systems which have failed to support them. Permanent Supportive Housing (PSH) is a formal intervention which seeks to offer stability and support to young people. This three-manuscript dissertation uses community-engaged mixed methods to understand sense of community, sense of place, and third places among young adults in PSH in Grand Junction, Colorado.

The first manuscript used longitudinal mixed methods to understand how PSH residents’ (N = 27) sense of community shifts over 1.5 years of living in PSH. We found that residents’ sense …

A Participatory Drone Mapping And Critical Physical Geography Of Water Security For Irrigation In Northern Ghana, Dinko Hanaan Dinko

Electronic Theses and Dissertations

Dam discourse frequently incorrectly assumes that their emergence unilinearly translates to an expansion of economic opportunities while not considering how dams become sites for the reproduction of inequality and injustice. This dissertation investigates how the politics of irrigation water access are nested in a complex web of physical materialities of the 'natural' environment and power relations, with lived consequences on differentiated social identities in semiarid Ghana. The research draws on transdisciplinary perspectives from political ecology, embodiment, critical physical geography, and mixed methods, including interviews, focus group discussions, surveys, participatory drone mapping, and laboratory analysis of soil biochemical properties. The study …

Guaranteed Income As A Structural Social Work Response To Homelessness In The United States, Katherine Hoops Calhoun

Electronic Theses and Dissertations

The number of projects exploring guaranteed income, or unconditional direct cash transfers, in the United States has exploded in recent years (Mayors for a Guaranteed Income, 2022a). Between June 2021 and June 2022, the number of city mayors engaged with the group Mayors for Guaranteed Income grew from 11 to 82 (Mayors for a Guaranteed Income, 2022b) and as of Winter 2023, there were over 90 guaranteed income demonstrations and projects in the United States (Guaranteed Income Community of Practice, 2023). Guaranteed income refers to direct cash transfers, often to targeted populations, that are unconditional, consistent, predictable, and flexible (Castro …

Terrain Cost Learning From Human Preferences For Robot Path Planning Using A Visual User Interface, Kaivalya Velagapudi

Electronic Theses and Dissertations

Robot navigation in terrains with limited exploration and limited knowledge has been a problem of interest in robotics due to the potential dangers that may arise during traversal. Due to the large number of path permutations within a complex and feature-rich real-world environment, and in the interest of saving time and ensuring safety, the robot should learn the optimal path without repeated exploration of the terrain. This can be accomplished by leveraging the path preferences of a human operator so that, with selective inputs, the agent can effectively learn a terrain-cost mapping in order to determine the optimal route, thereby …

Black Quarterback, White Masks: A Critical Analysis Of The Nfl Anthem Protests, Cody Walizer

Electronic Theses and Dissertations

The NFL anthem protests were and are an important cultural moment and social movement. The widespread emulation of the protest, and the adoption of the kneel as a symbol of unity, reverence, and silent objection demonstrates the protests’ continued relevance. This dissertation critically analyzes Colin Kaepernick’s protest through the lens of racial rhetorical criticism (Flores, 2016) and Fanonian communication studies (Towns, 2020). Through the case studies of David Brooks, Lee Siegel, and Colin Fleming, and their New York Times opinion pieces on Kaepernick from 2016-17, this study argues that the common discourses surrounding the protest exist within the strategic rhetoric …

Post-Translational Modification Of Proteins Via Ambient Air Pollutants And Endogenous Reactive Species, Rachel Lauren Davey

Electronic Theses and Dissertations

Proteins can react with reactive oxygen species (ROS) and reactive nitrogen species (RNS) to form post-translational modifications (PTMs), which can affect protein structure and function. The formation of 3-nitrotyrosine (NTyr) and dityrosine (DiTyr) upon reaction of proteins with ROS/RNS are two common PTMs studied due to their stability and irreversibility, as well as their ability to enhance the allergenicity of pollen allergens upon formation. Many common techniques used to study the formation of these PTMs can reliably detect the PTMs but can only provide semi-quantitative information due to many assumptions and limitations. In Chapter 2 we present an analysis of …

Systemic Risk And Blockchain Technology, Federico Colombo

Electronic Theses and Dissertations

After the crisis in 2008, blockchain and systemic risk have seen increasing interest. In this thesis I advocate for more research to be conducted on the two topics jointly after noticing a gap in the literature regarding the effects that using a blockchain based financial system could have on systemic risk. The thesis is an attempt to set the stage for future research, by describing the major sources of systemic risk, the most important characteristics of blockchain, and finally suggesting some topics for future research on systemic risk and blockchain in areas where blockchain could have the biggest impact.

Universal Basic Income (Ubi): A Cure-All Or Band-Aid?, Madison Beckner

Electronic Theses and Dissertations

With the triple crisis of capitalism looming and, in the U.S., a poorly performing welfare state, Universal Basic Income (UBI) has returned to popular attention. To assess whether this is warranted and, more importantly, to provide answer on the extent to which a UBI can or should be considered a cure-all, this work, first, examines the historical development of UBI proposals including those stemming from European Social Democrats and Libertarians. Next, pilot programs at the local, state, and national level are critically examined for their methodologies and empirical results. Turning, then, to theory on de-commodification, unpaid labor, and the equality-jobs …
