County Characteristics And Opioid Mortality Rates In The United States, Baksun Sung

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Opioid overdose deaths are not equally distributed across the United States. While some areas have a less severe problem with opioid abuse, others face serious challenges, which are affected by various social factors. To address that question, in Chapter 1, I investigate how opioid mortality trends differ according to opioid types, race, and region to identify susceptible populations and areas. In Chapter 1, I contend that synthetic opioid is a main trigger for the current opioid epidemic and that the epidemic is concentrated among blacks and in the Eastern United States. Next, the following studies examine how varying social vulnerabilities …

2. What challenges do pre-service teachers perceive in controversial issues teaching? …

Aerodynamic Implications Of A Bio‐Inspired Rotating Empennage Design For Control Of A Fighter Aircraft, Christian R. Bolander

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This dissertation presents an analysis of the aerodynamics for an aircraft using a novel, bio-inspired control system. The control system is a rotating tail, that is inspired by the way in which birds use their tail to control their flight. An aerodynamic model for a baseline aircraft and a bio-inspired variant are created by referencing well-known relationships for the aerodynamics of flight, which are then used to analyze the available flight envelope at which each aircraft can reach two different equilibrium states. An analysis of the total aerodynamic control authority of each aircraft is also included along with a preliminary …

Viability And Performance Of Rf Source Localization Using Autocorrelation-Based Fingerprinting, Joseph L. Ipson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Finding the source location of a radio-frequency (RF) transmission is a useful capability for many civilian, industrial, and military applications. This problem is particularly challenging when done “Blind,” or when the transmitter was not designed with finding its location in mind, and relatively little information is available about the signal before-hand. Typical methods for this operation utilize the time, phase, power, and frequency viewable from received signals. These features are all less predictable in indoor and urban environments, where signals undergo transformation from multiple interactions with the environment. These interactions imprint structure onto the received signal which is dependent on …

The Supreme Court And Presidential Elections: An Analysis Of Divisive Decisions And Judicial Review In Presidential Elections, Jeff Hastings

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A presidential election is, arguably, the most important event in the American political system. The Congress and the president are undoubtedly affected by the pressures and publicity of these events, but we have little understanding of whether the Supreme Court behaves differently in presidential election years. In this paper, I argue that the Supreme Court will experience more consensus in its decisions and make less use of judicial review because of the potential for heightened public scrutiny that can arise during the term overlapping with a presidential election. I test this claim using ordinary least squares regression. I find that …

Cardiac Ablation And Stimulation With Nanosecond Pulsed Electric Fields (Nspefs), Federica Serra

Biomedical Engineering Theses & Dissertations

Surgical ablation of cardiac tissue is the definitive treatment for the most common arrhythmia, atrial fibrillation. In current medical practice, myocardial tissue is often ablated by the application of radiofrequency (RF) currents which are delivered through an electrode to create lesions that block the electrical pathways that sustain reentrant arrhythmias and restore the normal heart rhythm. An alternative to RF is cryoablation, during which the endocardial or epicardial tissue is brought in contact with a cryoprobe. Both RF ablation and cryoablation have significant limitations. In RF ablation, tissue is heated in order to ablate it, but it is an open …

The Strong Black Woman ≠ Superwoman: Shattering Stereotypes Of Strength In Black Literature, Tricia Inez Thomas

English Theses & Dissertations

That the Black woman must be strong in order to endure the oppression she has been forced to withstand is a double-edged sword that equally contributes to both her dehumanization and willpower to survive. This project interrogates the patterns and characteristics that contribute to the schema of the strong Black woman through the examination of cultural texts foregrounded in biblical scriptures against literature written by prominent Black women through Beyoncé. Specific tropes explored include the jezebel, the mammy, and the sapphire with a conclusion that these harmful and dehumanizing stereotypes have cultivated a fallacious assumption of supernatural strength and resiliency …

The Importance Of An Educational Occupation-Based Work Program For Young Adults With Intellectual & Developmental Disabilities, Jennifer Zielinski

UNLV Theses, Dissertations, Professional Papers, and Capstones

Barriers to occupations and transitions to vocational opportunities can be difficult for adolescents and young adults with intellectual and developmental disabilities (I/DD)s to feel confident and pursue job opportunities. Some of the problems stem from the stigma related to the individual’s disability, the contexts surrounding them, and the performance of the work tasks expected. Individuals with I/DDs expressed that not having enough support in the community and the workforce creates significant obstacles to retaining a job. Occupational therapists (OT)s can play a unique role in transition and employment for individuals with an I/DD. With a focus on self-determination and successful …

Systems Dynamics Of The Anterior Cingulate Cortex And Hippocampus In Behavioral Switching, Spatial Working Memory, And Disease, Ryan Wirt

UNLV Theses, Dissertations, Professional Papers, and Capstones

The electrophysiological properties of the hippocampus (HC) and anterior cingulate cortex (ACC) are the central focus of research on learning, memory, and neurological disease. Previous research has shown that HC is essential for forming new memories, spatial navigation, and temporal processing. While the function of ACC, located within the medial prefrontal cortex, remains controversial, it has a role in long-term memory recall, processing pain, monitoring current state, learning, schema updates, and information integrations. Interactions between the ACC and HC occur during social memory, spatial working memory performance, and long-term memory recall. Notably, the HC and ACC are among the first …

The Transaction Costs Of Federal Environmental Policy Changes: The Effects Of The Temporary Covid-19 Cwa Rollback On Local Water Systems, Jesse Lee Barnes

UNLV Theses, Dissertations, Professional Papers, and Capstones

An institutional dilemma exists between the Clean Water Act (CWA) and the Safe Drinking Water Act (SDWA). US surface waters are protected from point-source pollution by the CWA. Community Water Systems (CWSs) that draw from these surface waters for potable purposes are required to treat that water to a level that meets SDWA health standards. Therefore, decreases in CWA regulations could lead to surface water quality declines and, thus, higher SDWA compliance costs for CWSs. This area of inquiry has become increasingly relevant due to Trump-era executive actions to try to decrease the federal government's role in multiple environmental policies, …

Ga(Y)Zing Backward: Queer Desire In Ovid, Shakespeare, And Scaimma, Falynn Blayre Brickler

UNLV Theses, Dissertations, Professional Papers, and Capstones

As Ovidian myth is a central influence on queer stories throughout time, I am interested in how the female/sapphic gaze impacts the retellings of these narratives. In this thesis, I analyze the action of the gaze as an expression of desire and discuss its multiple meanings in both text and performance. Through tracing the gaze within the queer/sapphic narratives of Shakespeare’s Twelfth Night and Sciamma’s Portrait of a Lady on Fire, I show that the gaze is an intersecting act through which non-normative desire is conveyed. In constructing the gaze as an ephemeral action of queer desire in practice, I …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The bacterium Fervidibacter sacchari is an aerobic hyperthermophile that catabolizes various polysaccharides and is the only cultivated member of the class Fervidibacteria within the phylum Armatimonadota. Among its glycoside hydrolase (GH) cache is an enzyme from GH family 50 (GH50), an understudied family with only 25 characterized representatives and two known activities from 1,518 predicted members in the Carbohydrate-Active EnZyme (CAZy) Database. Here, we expressed, purified, and functionally characterized an extracellular GH50 from F. sacchari called Fsa1572. Using colorimetric assays, we show it has novel β-1,4-glucanase activity and only weak agarose activity that is typical for GH50 enzymes. The purified …

Long-Range Regulation By The Shigella Virulence Gene Regulator, Virb, Cody Cris

UNLV Theses, Dissertations, Professional Papers, and Capstones

Nucleoid-structuring proteins (NSPs) in bacterial cells can exert gene regulatory effects over great distances on DNA. This contrasts with the traditional view of bacterial transcriptional regulation, where transcription factors bind cis-acting regulatory sites proximal (<250 bp) to promoters to influence gene expression. In Shigella species, the histone-like nucleoid-structuring protein (H-NS) transcriptionally silences many genes on the large (~220 kb) virulence plasmid. During host colonization, however, silencing by H-NS is alleviated by the anti-silencer protein, VirB, which remodels the H-NS:DNA complex. This transcriptional anti-silencing is mediated by VirB:DNA interactions and the modulation of DNA supercoiling, which lead to the up-regulation of virulence genes. VirB is a central regulator of Shigella virulence, but the mechanistic basis for transcriptional regulation is incompletely characterized. Here, I focus on the potential for VirB to regulate transcription from remotely located DNA binding sites. Employing complementary in vivo approaches, I assessed the spatial stringency of the VirB binding site and elucidated how varying cellular VirB levels impacts regulation over different distances. I also evaluated how a molecular roadblock on DNA influences remote regulation by VirB. Additionally, I developed control tools to validate the ability of VirB to spread along DNA, an activity of VirB that putatively drives transcriptional regulation. These data are consistent with transcriptional anti-silencing being driven by VirB spreading along DNA. Overall, these findings highlight how VirB is not a conventional transcriptional regulator and broaden our perspective on transcriptional control in bacteria. Furthermore, this work contributes to our understanding of long-range gene regulatory effects, which are frequently overlooked and poorly characterized in bacteria.

UNLV Theses, Dissertations, Professional Papers, and Capstones

Increasing numbers of people suffer from obesity and severe mental illness co-morbidly. If these conditions remain untreated, they can harm an individual's health and well-being. Unfortunately, there are very few programs currently available that target both management and improvement of these conditions simultaneously. Even so, despite the lack of programming options, it must be noted that the NEW-R program strives to reach those goals, although there hasn't been an abundance of literature supporting the effectiveness of this program. This poses a concern for occupational therapy practitioners who hope to assist their clients in managing these conditions as occupational therapy treatments …

Cell-Specific Mechanisms Of Microrna Modulation Of Anoctamin-1 (Ano1) In Oral Cancer, Daniel Hou

UNLV Theses, Dissertations, Professional Papers, and Capstones

Anoctamin-1 (ANO1) is a calcium-gated chloride ion channel with multiple physiological roles, including transepithelial ion transport, smooth muscle contraction, salivary secretion, and nociception. Recently, ANO1 has been identified to play a key role in cancer progression. ANO1 is overexpressed in different types of cancer, including oral cancer. ANO1 overexpression is commonly the result of ANO1 gene amplification on the chromosome 11q13 locus. In cancer cells, ANO1 upregulation has been reported to promote cell proliferation and migration of tumor cells, whereas ANO1 downregulation induces apoptosis through multiple signaling pathways. As such, ANO1 is now considered a useful biomarker for cancer progression …
