Improving Self-Care Measures Of Hypertension Through Implementation Of An Education And Action Plan, Crystal Celeste Huffaker

UNLV Theses, Dissertations, Professional Papers, and Capstones

Hypertension (HTN) is a leading cause of morbidity and mortality worldwide and one of the most common conditions seen by primary care providers. Current clinical practice guidelines recommend lifestyle modifications for patients with elevated blood pressure (BP) and diagnosed HTN. Despite these recommendations, many patients diagnosed with HTN make insufficient modifications to their lifestyle. The purpose of this project was to determine the impact of implementing an education session, with development of a patient action plan, along with 4-week, 8-week, and 12-week follow-ups on the adoption of self-care measures for HTN. Participants had their BP, height, and weight measured along …

Comparing The Incidence And Prevalence Of Oral Microbial Pathogens Selenomonas Noxia And Streptococcus Mitis Within The Unlv-Sdm Clinical Patient Population, Namgu Kim

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction: Selenomonas noxia (SN) is a gram-negative, anaerobic bacteria, which contributes to development and progression of periodontal disease. Some evidence now suggests Streptococcus mitis (SM), a gram-positive, facultative bacterium contributing to the etiology of dental caries and periodontal disease, may also influence the prevalence of SN within subgingival complexes. Based upon the overall lack of prevalence data, the objective of this study was to evaluate presence of SN and SM using qPCR among saliva samples taken from pediatric, adult, and orthodontic dental school clinics.

Methods: This study involved a retrospective analysis of previously collected saliva samples from an existing biologic …

Food Insecurity And Risky Sexual Behaviors Among College Students, Bertille Octavie Mavegam Tango Assoumou M

UNLV Theses, Dissertations, Professional Papers, and Capstones

Food insecurity and sexually transmitted infections (STIs) are growing public health problems in the United States. Young people in general, and particularly college students, exhibit high prevalence of food insecurity, STIs, and risky sexual behaviors (RSB). Food insecurity and STIs among college students can have short- and long-term impacts on their academic success and their lives. Several studies have reported an association between food insecurity and some risky sexual behaviors among specific populations including HIV-infected people and homeless people. However, little is known about the relationship between food insecurity and RSB among college students. Given the high prevalence of food …

Magneto Was Right: How The Holocaust Shaped An X-Men Antihero, Benjamin J. Morse

UNLV Theses, Dissertations, Professional Papers, and Capstones

Created in 1963 by Stan Lee and Jack Kirby, the X-Men property has extended beyond comic books over the last 30 years into television and film among other mediums. The initial premise of the canon, that mutants gifted with inherent superpowers were feared and hated by normal humans, has served as an allegory for discrimination against minorities on the basis of race, religion, and sexual orientation. Chris Claremont, the primary author of the X-Men from 1975-1991, did significant work introducing Judaism into the metaphor, in large part by making the series’ primary antagonist, Magneto, a Holocaust survivor working to prevent …

Still We Rise: A Black Feminist Qualitative Inquiry Exploring Black Women’S Experiences On Twitter, Yvonne C. Morris

UNLV Theses, Dissertations, Professional Papers, and Capstones

#WOCAffirmation was a hashtag created by April Reign in October 2017 in response to how Black women do not have the same supports of solidarity from populations who are non-Black women. Serving as a counterpublic, #WOCAffirmation embodied how Black women created space to affirm and amplify each other while also highlighting the harassment and abuse they experience in form of misogynoir on Twitter. As Black women are already under-researched in academia and fields within digital humanities, this study centered Black women while also highlighting oppressive systems of power in both physical and digital spaces. Using Black feminist thought as the …

Colonization Of The Philippines: An Analysis Of U.S. Justificatory Rhetoric, Johansen Christopher Pico

UNLV Theses, Dissertations, Professional Papers, and Capstones

The term “Filipino” offers more than a call to nationality; it also recalls the genesis of colonization in the Philippines. This thesis explores the colonial interventions of the United States in the Philippines at the turn of the 20th century, homing in on the Filipino education system as the United States’ primary method of colonizing the Filipino mind. Drawing from texts by Senator Alfred Beveridge, President William McKinley, the Philippine Commission, David Barrows, and Dr. Trinidad Pardo de Tavera, I offer an ideological criticism that demonstrates a cyclical nature between both justificatory rhetoric and ideology. Working with “ideological clusters,” this …

This research study examined the motivations people have to watch esports and how these motivations are related to engagement in esports communities, fan identity, sense of community, messages shared in communities, and spectating preferences. Previous research regarding esports and why people watch it was used to create three categories for esports spectating motivations: skill-based motivations, entertainment-based motivations, and relationship-based motivations. Quantitative analyses were performed after collecting survey data from college students at UNLV and additional fans from esports communities. The results showed that there were positive relationships between the various motivations and all aspects of esports fandom engagement, showing how …

Extreme Event Reconstructions For The Upper Fraser River Basin, British Columbia, Canada, Inga K. Homfeld

UNLV Theses, Dissertations, Professional Papers, and Capstones

Spring freshets and summer droughts have recently worsened in the Fraser River Basin, British Columbia, Canada, with significant impacts to the keystone Pacific salmon populations, the food and economic sovereignty of over eighty First Nations, and the western Canadian economy. These extreme events present a potential risk since, unlike many large and less hydroclimatically-complex and/or empounded watersheds, the Fraser River Basin is susceptible to a combination of unregulated spring freshet and summer drought events even within the same year. A major limitation for understanding past and future extreme event risk in the Fraser River Basin is that observational streamflow datasets …

UNLV Theses, Dissertations, Professional Papers, and Capstones

Urban population is expected to exceed 70% of the world’s total by the middle of the 21st century. Thus, growth in number as well as the sizes of the cities are certain in the near future. The urbanization rates will be much higher in the developing countries than the developed. Such phenomena are accompanied by conversion of land cover from its natural use to built up environment to accommodation growing population. Built up surfaces include road networks, buildings, parking lots and pathways. They are permanently impervious and hydrologically active surfaces. Large volume and discharges of runoff characterize impervious surfaces with …

Official Misconduct And Error Correction Mechanisms In Exonerated Death Penalty Cases, Kamali'ilani Theresa Elizabeth Wetherell

UNLV Theses, Dissertations, Professional Papers, and Capstones

There has been an average of approximately 3.9 death penalty exonerations annually in the United States since 1973 (DPIC, 2021). Wrongful convictions and executions constitute grave and irreversible errors. Studies show official misconduct is one of the leading causes for wrongful convictions and exonerations. Misconduct by police, prosecutors, and judges includes a wide range of behaviors such as coercing confessions, depriving rights to legal counsel, threatening witnesses, and concealing evidence. Operating under the due process model, the adversarial legal system is designed to detect and prevent any procedural violations of defendant’s rights, including official misconduct. Utilizing Packer’s (1964) due process …

Nursing Toolkit For Care Of The Pediatric Patient With Suicidal Ideation, Christine Young

UNLV Theses, Dissertations, Professional Papers, and Capstones

Nevada’s pediatric suicide rate is one of the highest in the country. Many patients require inpatient stabilization, either in an emergency department setting or on a pediatric unit, until they are ready for discharge to home or a subsequent behavioral health facility. In many instances, patients are assigned to nurses who have had no formal training on caring for pediatric patients with suicidal ideation. Providing care for these patients can increase nurses’ emotional stressors. Purpose: The purpose of this DNP project was to increase the knowledge of pediatric nurses in Nevada using a nursing toolkit containing information to aid in …

Geometric Quality Assessment Of A Modular House Using Bim And Photogrammetric Point Clouds, Preetam Kapsikar

UNLV Theses, Dissertations, Professional Papers, and Capstones

As-built documentation of modular structures is an important set of records for a project, that consist of construction drawings and specifications, project design modifications, prefabrication, and component assembly. In particular, manual geometric quality assessments of a structure’s prefabricated components are generally fraught with errors, making it extremely difficult to compare the as-built construction with the specified drawings, which affects the project. Furthermore, if the prefabricated components are manufactured with errors, this can result in construction schedule delays and high additional costs due to rework. Several technologies, such as point cloud data generated using laser sensors and LiDAR, have been developed …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The COVID-19 pandemic interrupted established communication practices for organizations across the globe. While much attention focused on the adaptability of large corporations, less attention has been paid to how nonprofit organizations have responded. At a time when the COVID-19 pandemic was creating ripple effects in social service needs, nonprofit organizations that did not directly address public health still fulfilled urgent missions and needed to communicate their legitimacy to assist with community resilience efforts. This study discovered the roles narratives and social media played in nonprofit organizational crisis communication during the COVID-19 pandemic through interviews with 12 participants. Using situational crisis …

Perceptions Of The Built Environment Among Older Adults Who Live In Age-Restricted Communities Compared To Those Who Do Not In Southern Nevada, Sandra Annan

UNLV Theses, Dissertations, Professional Papers, and Capstones

As Americans are living longer, there has been exponential growth in the number of older adults. Growth in the aging population has created unique challenges. As seniors age, they face many changes in their health, financial stability, and lifestyle, making it challenging to remain independent. The inability to remain independent can be a stressful and depressing experience for older adults. Studies show that most seniors prefer to stay in their current living environment as they age, or age in place, rather than move into senior housing or other available housing options designed for aging. This study investigates how perceptions about …

Current-Mode Photon-Counting Circuit With Sige Bicmos Input Stage, Gonzalo Guadalupe Arteaga

UNLV Theses, Dissertations, Professional Papers, and Capstones

Continued advances in photodetector technology have helped improve the imaging capabilities of LiDAR systems or other time-of-flight imaging efforts. As a major part of the receiver within a LiDAR system, the photodetector can offer features such as faster rise times, narrower pulse widths, or larger gains to help achieve greater timing resolution or sensitivity to faint light levels. These benefits, however, are contingent on the ability of the accompanying readout circuit to reliably process the fast, electrical signals generated by the photodetector. While common front-end circuits involve the use of feedback amplifiers, their stability can become a major concern at …

Analysis Of High-Speed Rail Operations Using Vissim Simulation To Determine Access Charges And The Impact Of Incidents On A Shared Network, Komal Sree Teja Boyapati

UNLV Theses, Dissertations, Professional Papers, and Capstones

Shared High-Speed Rail (HSR) networks are networks where two or more railway operators use the same railway network infrastructure for train operations. The train operations in the shared HSR network can be composed of different types of trains operating at different speeds with varying stops at stations in a network. The interactions between different types of trains in the shared HSR network depends on the characteristics of the network’s infrastructure and train operations, and affect the capacity of the network. When a rail operator who owns the infrastructure allows other operators to access its infrastructure, the additional traffic will lead …

Validation Of Novel Obstructive Sleep Apnea Treatment With Silicone Gel Experimental Models, Dustin Walter Burd

UNLV Theses, Dissertations, Professional Papers, and Capstones

Predictive modeling to increase treatment success rates for surgical procedures is becoming more common in the scientific community. For obstructive sleep apnea (OSA), modeling has been predominately performed using computers as opposed to experimental models. Computer simulation saves time by eliminating the need to fabricate complex experimental models but comes at the expense of insight gained through physical observations made in real time. Experimental models for studying OSA are needed to validate computational work, provide perspective on anatomical scale and demonstrate complex deformations in real time. This work addresses prior hurdles in experimental model fabrication with a novel process using …

The Economy Of (Dis)Honor In The Americas: A Transnational Rupturing Of American Literature Through Faulkner, García Márquez, And Silko, Clayton Neil Cobb

UNLV Theses, Dissertations, Professional Papers, and Capstones

Honor is misunderstood within popular culture, but it is also misunderstood within academic contexts. This is due to a decoupling of the term from its long historical significance, a significance that must not be ignored. That is because honor in the Americas is a structure of the hemisphere’s colonial legacy, its manifestation in the cultural fabric a result of the invasion of the continents by European settlers and colonizers. In the case of history, philosophy, and social science, the study of honor is beginning to undergo appropriate theorization to recognize that legacy; however, within literary studies disciplines, critical understanding of …

The Effect Of Body Armor On Pulmonary Function And Repeated Sprint Performance, Dustin Dunnick

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction: Tactical athletes face the unique task of performing physically demanding occupational duties often while wearing torso-borne loads. While pulmonary function has been shown to decrease while wearing plate-carrier style body armor, there has yet to be a study using the more accurate measurement of plethysmography to determine exactly why. Additionally, the inspiratory muscle’s pressure generation capabilities and how they respond to a repeated running sprint test while wearing body armor are unknown. Therefore, the purpose of this dissertation was to examine how body armor affects pulmonary function, inspiratory muscle strength, and athletic performance during repeated, high-intensity sprints.

Methods: Twelve …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The vibrational contribution to the second hyperpolarizability (γ) of gas phase H2 was measured using electric field induced second harmonic generation. Measurements were made for the pure vibrational 3-0 Q(J) overtone transitions (v=0,J → v’=3,J for J = 0,1,2,3). Measured intensities were found to be 4-14% larger than ab initio calculations. The first chapter of this thesis provides an introduction to nonlinear optics, second harmonic generation, and the tensor nature of hyperpolarizabilities. The second chapter provides theoretical expressions for γ and relevant static and Raman polarizabilities. The third chapter covers the experimental design and electric field induced second harmonic generation. …

Light Conditions During Desiccation And Rehydration Impact The Recovery Of Cultured Timmiella Crassinervis, Sotodeh Ebrahimi

UNLV Theses, Dissertations, Professional Papers, and Capstones

Many terrestrial mosses of xeric environments experience excess light during extended periods of desiccation. While dry or hydrated, excess light energy can lead to formation of reactive oxygen species and photoinhibition (e.g. damage to Photosystem II) which affects photosynthetic stress and efficiency. This study aimed to determine the effect of duration dry and light intensity (PAR) on cultured shoots of the chaparral moss Timmiella crassinervis, as well as to elucidate the optimal rehydration light conditions for this species. I hypothesized that 1) mosses exposed to higher light intensities during desiccation would incur more damage upon rehydration than those exposed to …

Tectonic Evolution Of The Tucki Mountain Metamorphic Core Complex, Southeastern California: Evidence For Late Cretaceous Extension Within The Sevier-Laramide Orogen, William Killey Barba

UNLV Theses, Dissertations, Professional Papers, and Capstones

The exhumation of Cordilleran metamorphic core complexes from mid-crustal depths in the western U.S. Basin and Range Province has been classically associated with Cenozoic extension. However, recent studies reveal that extensional tectonic exhumation of numerous metamorphic core complexes initiated during the Late Cretaceous. New geologic mapping and structural analysis integrated with geochronology and thermochronology data provide evidence for a Late Cretaceous extensional shear zone, previously interpreted as Miocene in age, within the Tucki Mountain metamorphic core complex on the western flank of Death Valley, California. The shear zone occurs within the immediate footwall of the Miocene-Pliocene Tucki Mountain detachment fault …
