Some Graph Laplacians And Variational Methods Applied To Partial Differential Equations On Graphs, Daniel Anthony Corral

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this dissertation we will be examining partial differential equations on graphs. We start by presenting some basic graph theory topics and graph Laplacians with some minor original results. We move on to computing original Jost graph Laplacians of friendly labelings of various finite graphs. We then continue on to a host of original variational problems on a finite graph. The first variational problem is an original basic minimization problem. Next, we use the Lagrange multiplier approach to the Kazdan-Warner equation on a finite graph, our original results generalize those of Dr. Grigor’yan, Dr. Yang, and Dr. Lin. Then we …

Measuring Perceptions Of Safety Among Staff And Women Clients In A Prison Substance Abuse Program, Jaclyn Parker Keen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Women who are involved in the criminal justice system have unique pathways to criminality. Prevailing themes of dysfunctional and traumatic relationships, addiction, mental illness, poverty, and having limited human and social capital dominate the women’s pathways perspective. A large body of existing research focuses on how these unique risk factors require unique treatment options for women while they are incarcerated in jail or prison settings. Entering prison can be an overwhelming experience and prison is an environment that has a high potential for conflict and violence. In order to be safe in prison it requires that women both feel protected …

Family Functioning In Youth With Bipolar Disorder, Kayla Fobian

UNLV Theses, Dissertations, Professional Papers, and Capstones

Family functioning encompasses a family’s ability to maintain an environment that supports and benefits each member of the family. Among families of youth with a bipolar disorder (BD), family functioning is impaired compared to healthy controls. However, few studies have examined family functioning across psychopathology in youth. Additionally, few studies have examined which symptoms (depressive, manic, or externalizing) are most strongly associated with family functioning. Therefore, the purpose of this manuscript is to benchmark impairments in family functioning in youth with BD compared to youth with other psychiatric disorders and to examine the differential influence of depressive, manic, and comorbid …

Changes In Cognitive Networks As A Result Of Sport-Related Concussion, Grace J. Goodwin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Given the high prevalence of concussion in sports, assessment of cognition has become a standard part of athletics, and results are used to inform return to play decisions. Neurocognitive measures (e.g., ImPACT) generate cognitive composite scores from individual subtests, and these scores are compared at baseline and post-concussion. Declines in scores provide evidence for concussive injury, and athletes undergo repeated assessments until their scores and symptoms improve. Recent research suggests that changes in the associations between test scores may provide important information about cognitive recovery. A network framework may help identify post-concussive cognitive changes that may not be apparent when …

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 …

First-Day Expositional Interviews, Iterative Training, And Participant Skill In Descriptive Experience Sampling, Cody Michio Kaneshiro

UNLV Theses, Dissertations, Professional Papers, and Capstones

Descriptive experience sampling (DES) is a method of describing inner experience (i.e., directly apprehended thoughts, feelings, sensations, etc.). DES includes “iterative” sequences of random, natural-environment, beeper-driven sampling of inner experiences followed by an expositional interview that seeks to apprehend and describe those inner experiences in high-fidelity. DES investigators claim that these iterative sequences increase the participant’s DES skills. The present study tests that claim by investigating whether participants demonstrate higher skills in their very-last-sample interviews than they exhibited in their own very-first-sample interviews. The very-last-sample and very-first-sample interviews of six participants were quantitatively and qualitatively examined. We found that participants …

Ultrasonography-First Imaging Algorithm For Acute Appendicitis Diagnosis, Steven Lamar Moore

UNLV Theses, Dissertations, Professional Papers, and Capstones

Acute appendicitis (AA) is the most common cause of acute abdominal pain requiring surgery in pediatric, adult, and pregnant patients. Several etiologies are believed to trigger luminal obstruction, which causes mucus and bacteria proliferation, resulting in inflammation and wall tension with subsequent necrosis and rupture of the appendix. Most AA patients present with the primary complaint of abdominal pain, which Murphy first described the characteristic diagnostic sequence seen in approximately 50% of patients as colicky centralized abdominal pain with subsequent vomiting with the migration of pain to the right lower quadrant (RLQ), specifically, the right iliac fossa. The typical AA …

Attentional Focus And The Development Of Skilled Performance, Harjiv Singh

UNLV Theses, Dissertations, Professional Papers, and Capstones

A central question in the development of skilled movement is: how a performer should focus their attention while preparing for the execution of a motor skill? Considerable evidence has shown that directing attention towards an intended movement effect (i.e., external focus) results in performance benefits relative to focusing on body movements (i.e., internal focus). While most of the previous research has emphasized the effects of internal versus external foci, evidence also suggests that external foci located at greater distances from the body (distal foci) are more effective than external foci located in greater proximity to the body (proximal foci) and …

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 …

Comparative Effects Of High-Intensity Interval Warm-Up Exercise And Bronchodilator On Exercise-Induced Bronchoconstriction In Children With Mild Asthma, Michael Wong

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose: The troubling link between obesity and asthma in children, along with greater associated detrimental health effects, warrants investigation to better understand the mechanisms driving this relationship as well as its consequences, especially during exercise. Bronchodilators and interval warm-up exercises are recommended by the American Thoracic Society to prevent exercise-induced bronchoconstriction (EIB). Whether interval warm-up exercise can prevent EIB to the same extent as bronchodilators in asthmatic children is unknown but clinically important. Therefore, the first purpose of this study is to investigate the effects of obesity on pulmonary function, exercise tolerance, and exercise-induced bronchoconstriction in asthmatic children. The second …

Horse Loose: Essays On Fear And Attachment, Alyse Burnside

UNLV Theses, Dissertations, Professional Papers, and Capstones

I began writing my thesis about my grandmother, who lived out the last few years of her life as a new age healer speaking in tongues and believing she was the channel for an ancient Lemurian shaman. We were not close until the very end of her life, and even then I felt far away from her. Not in the least because of her estrangement with the rest of my family. I tried and tried to write about her but always ran up against her mystery. She was not a woman many knew, and if you did know her, you …

The Responsiveness Of Muscle Strength Tests In Adults With Intellectual Disabilities, S. Weterings, A. Oppewal, S. M.A. Bierma-Zeinstra, T. I.M. Hilgenkamp

Physical Therapy Faculty Research

Background Muscle strength is both a strong predictor for future negative health outcomes and a prerequisite for physical fitness and daily functioning of adults with ID. Therefore, it is important to be able to monitor the muscle strength of adults with ID over time. The aim of this study is to assess the responsiveness of five field tests that measure muscle strength and endurance (grip strength, hand-held dynamometry of leg extension and arm flexion, 10RM-test of the seated squat and the biceps curl, 30-s chair stand and the 5-times Chair stand) in adults with ID after a 24-week resistance-exercise training …

Method: Participants from the Emory Healthy Brain Study (463 women, 200 men) who were administered the AVL were …

Dawn Of A Silver Millennium: Millenarianism, Futurity, And Utopia In Pretty Guardian Sailor Moon, Matthew Dentice

Far West Popular Culture Association Annual Conference

The story of Sailor Moon, told and retold in countless forms in the thirty years since the original manga’s publication, is imbued with a cosmic sense of time. The modern-day protagonists’ personal journeys are tightly interwoven with the distant past of the Silver Millennium and the far future of thirtieth-century Crystal Tokyo. But only the manga is fully willing to grapple with what the future means for its own present moment. Written in the early 1990s during Japan's "Lost Decade," Pretty Guardian Sailor Moon dramatizes the angst that accompanies the imminent arrival of a new millennium. As the Sailor Guardians …

Into The Woods: Freedom And The Forest In The Hunger Games, Robert B. Hackey

Far West Popular Culture Association Annual Conference

Forests are contested terrains in literature. The woods are a bucolic setting far removed from the hectic, bustling world of the city or the grueling challenges of industrial life. At the same time, however, the forest challenges us – in the woods, we must take stock of ourselves, overcome unfamiliar obstacles, and face our fears. The forested settings of the Hunger Games – both natural and manmade – force tributes to wrestle with the nature of human freedom. Drawing upon political theorists from Thomas Hobbes to Isaiah Berlin, my paper also explores how tributes face a choice between positive and …

“A Meaningless Institution”: Allen Ginsberg And The Struggle To Resist Dehumanization, James Altman

Far West Popular Culture Association Annual Conference

This presentation details how in poems such as “A Meaningless Institution,” “Howl,” and “American Change” Allen Ginsberg depicts individuals striving as best they can to maintain their freedom, especially freedom of thought in the face of lockstep conformity. In doing so, they seek to hang onto and reassert their humanity. In virtually every line, Ginsberg’s ideas about free speech, democracy, patriotism, inclusiveness, the environment, and community collided with the dehumanizing ideals of mainstream Cold War America. Ginsberg’s reverence for the United States as celebrated by his artistic “father” Walt Whitman functions as the catalyst for him to protest what the …

"Of Backstories And Epiphanies And Such: A Formalist's Analysis Of Dallas Jenkins' Youtube Series 'The Chosen.'", Richard Logsdon

Far West Popular Culture Association Annual Conference

Of Backstories and Epiphanies: A formalist’s analysis of Dallas Jenkin’s The Chosen

In this essay, I attempt a formalist’s analysis of YouTube sensation The Chosen, so far a two part, sixteen-episode series about Jesus. In taking a formalist’s approach to this series, I seek the unifying principle holding the episodes of The Chosen together and determining the selection and arrangement of parts.

Presented from perspective of Jesus’ followers, the series' episodes make use of backstories and epiphanies to convey the unifying message that Jesus Christ was God and man. Those who experiences the epiphanies, often occurring in backstories intended to …

Quantification Of Organic Carbon Sequestered By Biogenic Iron Sulfide Minerals In Long-Term Anoxic Laboratory Incubations, Nader Nabeh, Cheyenne Brokaw, Aude Picard

Life Sciences Faculty Research

Organic carbon sequestration in sedimentary environments controls oxygen and carbon dioxide concentrations in the atmosphere. While minerals play an important role in the preservation of organic carbon, there is a lack of understanding about the formation and stability of organo-mineral interactions in anoxic environments, especially those involving authigenic iron sulfide minerals. In this study, we quantified organic carbon and nitrogen sequestered in biogenic iron sulfide minerals co-precipitated with sulfate-reducing bacteria (SRB) in freshwater and marine conditions in long-term laboratory experiments. The amounts of C and N associated with biogenic iron sulfide minerals increased with increasing cell biomass concentrations available in …

"We Could And Should Be Doing More": Domestic Violence Advocates' Perceptions Of Agency Training, Elia Del Carmen Solano-Patricio, Shon M. Reed

Undergraduate Research Symposium Posters

Domestic violence advocates are an under-represented part of the criminal justice system. Because of the role that advocates play in supporting diverse populations of victims/survivors, it is important that they be given the opportunity to express their needs regarding onboarding and supplemental trainings. The current study gathers qualitative data from domestic violence advocates around the United States and explores advocates' recommendations for future trainings. Participants generally expressed the need for increased training regarding various victim sub-populations (e.g., LGBTQ+). Future policy implications and avenues of research will be presented.

Recognition Memory For Auditory And Visual Objects, Sharica Lee, Alexa Salomon, Kevin Mohawk, Laura Werner

Undergraduate Research Symposium Posters

Visual object memory is superior to auditory object memory. Our past research showed that auditory memory was less sensitive to divide attention during study, which may be attributable to representational differences between auditory memory and visual memory.

In the present study, we attempted to equate auditory and visual memory representations in order to adequately investigate the impact of dividing attention on recognition memory.

Recognition memory is thought to rely on two distinct processes, recollection and familiarity. Recollection involves the retrieval of precise qualitative detail and is the most sensitive to dividing attention.

Infants' Intermodal Knowledge Of Gender Using Faces And Voices, Bijoux Cheun, Christina Saliba, Alexis Rice, Marian Espina

Undergraduate Research Symposium Posters

Infants begin to use intermodal knowledge to match male and female faces to the corresponding voice, in their first year of life.

Infants have more experience with female faces which should lead to greater intermodal knowledge of female faces.

Previous studies have found inconsistent results. This could be due to the type of stimuli used.

This study uses several pairs of static and dynamic faces to investigate how methodological differences may impact infants' performance.
