A Performer’S Guide To Richard Danielpour’S Spirits In The Well: A Cycle Of Four Songs For Soprano And Piano With Lyrics By Toni Morrison, Christina Louise Chenes

UNLV Theses, Dissertations, Professional Papers, and Capstones

Richard Danielpour’s (b.1956) song cycle Spirits in the Well (1998) uses four poems penned by Toni Morrison (1931-2019), specifically for Danielpour’s musical setting. Spirits in the Well remains virtually unknown to the general public and artists, as it has never been professionally recorded, despite having been frequently performed by famed soprano Jessye Norman (1945-2019). This document introduces singers to Spirits in the Well by offering a performance guide to the song cycle; it presents information on the text, musical style, structure, form, technical vocal challenges, and dramatic demands that this work places on a singer. Brief background information is provided …

Terrestrial Planet Formation In M-Dwarf And Binary Star Systems, Anna C. Childs

UNLV Theses, Dissertations, Professional Papers, and Capstones

I examine circumbinary terrestrial planet formation in a gas free environment around various binary systems and terrestrial planet formation in a gaseous environment around M-dwarfs. While terrestrial cirumbinary planets have yet to be observed, this is likely due to observational bias. Motivated by recent observations of highly misaligned circumbinary gas disks, I perform a suite of n-body studies to understand the properties of terrestrial planets around various binary systems. In a polar alignment, a circumbinary disk is inclined by 90 degrees relative to the binary orbital plane. I find that terrestrial planet formation in a polar configuration may be as …

Queens Of Discourse: An Observation Of Black Insta-Comediennes, Naoka Foreman

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study observed the ways Black females on Instagram perform sociopolitical humor online to push back against the dominant culture in this digital age – maintaining the Black comedy tradition. It explores and illuminates the strategies of resistance exhibited by Instagram comediennes through a textual analysis informed by minor discourse, intersectionality, and critical feminist theories. Each comic’s personae were investigated and their content on Instagram was randomly selected and coded then grouped into themes. Black insta-comediennes shared Black feminist thought, modified beliefs about Black females or conventionality, and negotiated with the industrial demands of show business to earn subjectivity on …

Psychometric Properties Of The Eating Disorder Examination Questionnaire: Factor Analysis And Measurement Invariance By The Intersection Of Race And Gender, Jessica H. Habashy

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Eating Disorder Examination Questionnaire (EDE-Q) was originally validated in non-Hispanic White women and over the past two decades has become widely used as an eating pathology screening measure in college students. However, the original factor structure has generally failed to replicate across most studies, particularly among culturally diverse samples. The current study examined the factor structure and measurement invariance of the EDE-Q in a large sample of gender and racially/ethnically diverse college students. Participants included a racially and ethnically diverse sample of men and women from two universities. I first conducted exploratory factory analysis (EFA) to examine the factor …

“Who Says Lowriders Are Only For Men?”: Lowriders In Las Vegas, Nevada, Alejandra Herrera

UNLV Theses, Dissertations, Professional Papers, and Capstones

Since its creation, Las Vegas, Nevada, has been associated with casinos, nightlife, drinking, and neon lights. Las Vegas is not associated with Lowriders. Historically, lowrider vehicles are associated with crime, gangs, and male drivers. When lowriding comes to mind, Lowriders are associated with major cities in California, Texas, New Mexico, Arizona, and Colorado. Lowriders are not usually visualized as having female participants or as being present in Las Vegas. This thesis highlights members of the Lowrider community (especially Christal Leyva, Ivelys Franco, and Juanita Salazar) through the use of oral interviews and personal correspondence. The Lowriders interviewed for this thesis …

Positive Solutions To Semilinear Elliptic Equations With Logistic-Type Nonlinearities And Harvesting In Exterior Domains, Eric Jameson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Existing results provide the existence of positive solutions to a class of semilinear elliptic PDEs with logistic-type nonlinearities and harvesting terms both in RN and in bounded domains U ⊂ RN with N ≥ 3, when the carrying capacity of the environment is not constant. We consider these same equations in the exterior domain Ω, defined as the complement of the closed unit ball in RN , N ≥ 3, now with a Dirichlet boundary condition. We first show that the existing techniques forsolving these equations in the whole space RN can be applied to the exterior domain with some …

Application Of Lanthanides In Wastewater Treatment And Water Reuse, George William Kajjumba

UNLV Theses, Dissertations, Professional Papers, and Capstones

Much of the world’s population feed on grains (wheat, rice, and corn). Corn is as sensitive as it is productive. This thirsty, fast-growing plant goes into thermal shock in drought. In 2014, California lost over $2.2 billion in crop production due to drought. The Horn of Africa (in 2011) and Sahel (in 2012) faced humanitarian disasters due to food and water scarcity. The higher frequency of climate change and the erratic nature of rain, combined with underlying economic and social vulnerabilities, has meant that food and water scarcity is here to stay. To improve food and water scarcity, water reclamation …

UNLV Theses, Dissertations, Professional Papers, and Capstones

In today’s complex workplace, organizations have implemented mentoring programs to serve the needs of employees by providing career development and personal support. Mentoring relationships provide a variety of vocational, psychosocial and role modeling functions to protégés. Previous educational psychology research has examined the role of mentoring as it relates to self-regulation, self-efficacy, career promotions, motivation and other constructs. Epistemic cognition relates to the understanding of the nature of knowledge and knowing. Epistemic cognition relates to the development, in which one’s understanding of knowledge evolves from a belief that knowledge is finite, must be passed down by expert authorities toward an …

A Wearable Electronic Monitoring Device For Low Pressure Garment Applications And Temperature Analysis For Prevention Of Ulceration And Infection, Francisco Mata Carlos

UNLV Theses, Dissertations, Professional Papers, and Capstones

The healing process of several medical conditions related to venous insufficiency and burn scar management can be improved by the proper application of pressure. Current practices for applying pressure to an extremity do not guarantee the consensus ideal interface pressures for such medical conditions. Applying a low pressure range (within 15 – 40 mm Hg) is challenging due to many factors, but especially because the actual pressure applied by a compression garment used on a patient is unknown. The proposed device, used to sense and display low pressure values, is described in detail throughout the chapters of this thesis.An electronic …

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that has emerged over the past 10-12 years as safe, affordable, portable, easy to use, and potentially efficacious adjuvant training intervention in several aspects of human performance. tDCS has been shown to be able to improve both cognitive and motor function in a wide variety of populations such as young adults, older adults, stroke, Parkinson’s disease, and many others. However, the majority of tDCS research has been conducted in the motor system of healthy young adults, which will also be the focus of this dissertation.The basic effects of tDCS …

Neo Development Of The Workplace Environment In Response To Evolutionary Social Changes, Dafne Odette

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study is to identify the needs and wants of remote workers to support their health and well-being in response to evolutionary social changes. Many workers were once tethered to live in the city where their job office resided. Additionally, economic forces have long been a deciding factor in where one lives. The COVID-19 virus of 2020 provided an opportunity for many people to work remotely to control the virus (Latham, Higgins, & Judish, 2020). This has allowed people to retain higher salaries while living in rural areas where the cost of living may be lower. In 2021, some businesses …

An Educational Intervention In The Emergency Department For Adults Experiencing Vaso-Occlusive Crisis, Chericka S. Reese-Martin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: Sickle cell anemia, often referred to as sickle cell disease (SCD), is an inherited blood disorder that affects millions of people globally and affects more than 100,000 Americans, mostly of African or Hispanic descent. The SCD arises from a genetic defect that alters the structure of hemoglobin. The modified hemoglobin causes red blood cells (RBCs) to become stiff, sticky, and sickle shaped. These deformed RBCs block blood flow, cause severe pain, organ and joint damage and strokes. The sickled cells do not deliver oxygen to organs and tissues as healthy cells do, causing slow, inevitable damage over decades and …

Chimaera: A Collection, Robert Ren

UNLV Theses, Dissertations, Professional Papers, and Capstones

Chimaera is a collection of short stories as well as excerpts from a novel in progress, Cassandra & Charon. While this collection bears some resemblance to a short story cycle, these selections are not intended to be published together outside of this dissertation. Nevertheless, this dissertation features these selections side by side as these stories and chapters overlap thematically and consequently create resonances that would not exist otherwise. The short stories predominately feature Chinese American characters often as outsiders or third parties to other relationships. Other stories also feature retellings of classic stories including Goldilocks, Snow White, and Dracula, at …

Regional Health Benefits Of The Nevada Renewable Energy Initiative, Alireza Rezaee

UNLV Theses, Dissertations, Professional Papers, and Capstones

In recent years, there have been tremendous efforts to replace fossil fuels with renewable energy to mitigate emissions of greenhouse gases and air pollutants in the United States. Nevada was among the first states that established the renewable portfolio standards (RPS), requiring a certain percentage of electricity sold to the customers for consumption coming from renewable resources. The recent Nevada Senate Bill 358, signed by Nevada’s Governor in 2019, set a target that by 2030 not less than 50% of electricity sold in Nevada should come from renewable resources. This research investigates how this Bill could provide health benefits for …

Locating A Marketplace At The Ancient Maya City Of Lakamha’, Mexico Using The Configurational Approach, Jonathan Roldan

UNLV Theses, Dissertations, Professional Papers, and Capstones

In some cases, plazas that undergo archaeological testing for marketplace activity are identified using a method known as the configurational approach. This preliminary research method compares plaza locations to a list of associated features, often treated as a list of criteria. However, this approach has been criticized for its speculative nature and the equifinality of the results. Additionally, some argue that these “criteria” are only a list of assumptions. Until now, the configurational approach has received little attention due to its limitations and speculative nature, yet it remains an integral part of the preliminary process in marketplace research. This project …

Consumers Of Sex, Romance And The Spectacle: An Ethnographic Study Of Female Tourists In Bangkok’S Adult Entertainment Zones, Jason H. Scott

UNLV Theses, Dissertations, Professional Papers, and Capstones

This research is an ethnographic study of female sex tourism in Bangkok, Thailand and explores how women, as consumers, participate in activities and spaces that were historically reserved for male tourists. Much of the existing scholarly literature investigates the way men from the global North participate in sex tourism practices. Very little attention, however, has been given to the way female tourists engage as consumers in the global sex tourism industry. Studies conducted in the Caribbean suggest that sexual consumption practices among female tourists are dichotomously different from men because of traditional gender roles and sexual scripts. To guide this …

Efficient Networks-On-Chip Communication Support Solutions For Deep Neural Network Acceleration, Binayak Tiwari

UNLV Theses, Dissertations, Professional Papers, and Capstones

The increasing popularity of deep neural network (DNN) applications demands high computing power and efficient hardware accelerator architectures. DNN accelerators use a large number of processing elements (PEs) and on-chip memory for storing weights and other parameters. A significant challenge is faced when designing a many-core DNN accelerator to handle the data movement between the processing elements. As the communication backbone of a DNN accelerator, networks-on-chip (NoC) plays an important role in supporting various dataflow patterns and enabling processing with communication parallelism in a DNN accelerator. However, the widely used mesh-based NoC architectures inherently cannot efficiently support many-to-one (gather) and …

Promoting Paradise: The Recruitment Of Volga German Immigrants To The American Midwest, 1870-1900, Kassidy N. Whetstone

UNLV Theses, Dissertations, Professional Papers, and Capstones

In 1762 and 1763, Russian tsarina Catherine II issued manifestos encouraging foreign immigration throughout Russia, and received an overwhelming response from German farmers. These farmers, who would later be known as Russian Germans, Mennonites, or Volga Germans, quickly gained a reputation for their successful farming skills. As a result, following the Homestead Act of 1862, United States recruiters used promotional land advertisements to entice the farmers to migrate to the Midwest. The posters often depicted “open,” abundant lands in paradise. Upon arrival, however, the Volga Germans faced a reality starkly different from what the advertisements had promoted. This paper analyzes …

The Effects Of A Telehealth Exercise Intervention On Balance In Adults With Down Syndrome, Mark Barton, Kristina Guerrero, Andrew Martinez, Alexandria Umagat

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: People with Down syndrome (Ds) often present with balance deficits, which compromise their safety during daily activity. While evidence shows that exercise can improve balance in the Ds population, it is unclear if a telehealth method will elicit similar benefits. We aimed to examine the effects of a virtual exercise program on balance in adults with Ds.

Methods: Twenty participants completed a 12-week telehealth exercise program based on the Mann Method. Balance testing took place before and after the intervention, which included: Timed Up and Go (TUG), Modified Clinical Test of Sensory Interaction in Balance (MCTSIB), Frailty and Injuries: …

Diagnostic Ultrasound As A Reliable Tool To Measure Multifidus Thickness, Katherine Shigemoto, Valeria Garcia Arteaga, Jessie Peterson, Nathan Gentry

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction: Lower back pain (LBP) is a recurrent issue in the general population, though it is generally seen 2-3 times more frequently in those who undergo transfemoral amputations, being considered worse than phantom limb or residual pain. It is suggested that LBP is more common in those who have a transfemoral amputation than those who have a transtibial amputation. Research thus far has seemed to focus on identifying links between unilateral amputation and LBP rather than bilateral.

The multifidus muscle is the most important dynamic stabilizer of the lumbar spine, accounting for two- thirds of lower lumbar segmental stability. A …

The Limits Of Critical Rhetoric: Towards A Postcritical Orientation, James Bezotte

UNLV Theses, Dissertations, Professional Papers, and Capstones

In 1989, Raymie McKerrow’s essay “Critical Rhetoric: Theory and Praxis” served as a culmination for a new mode of rhetorical analysis that would reshape the field in the decades following. His essay combined the works of Michel Foucault and other rhetoric scholars such as Michael McGee, Maurice Charland, and Philip Wander to create the method of discourse critique called “critical rhetoric.” Essential to this practice are McKerrow’s equally important and interrelated “critique of domination,” “critique of freedom,” and “permanent criticism.” These components respectively help critics identify where social change should occur within discourses of power, motivate realignments of power for …

Political Discussion And Disagreement: Seeking Validation Through News Media, Michael Carmona

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study explores how often individuals discuss politics with family/friends and acquaintances, how often individuals are exposed to disagreement during those discussions, the strategies they use to respond to political disagreement, and the use of news media following those disagreements. Through the lens of Uses and Gratifications theory, this study examined these elements through an online survey of U.S. adults. The results of this study did not support Hopmann’s, Bjarnøe’s, and Wonneberger’s findings about the relationship between the frequency of political disagreement and the strategies for responding to that disagreement. This study highlights how the discussions and disagreements we have …
