Identification Of Factors Contributing To Traffic Crashes By Analysis Of Text Narratives, Cristian D. Arteaga-Sanchez
Identification Of Factors Contributing To Traffic Crashes By Analysis Of Text Narratives, Cristian D. Arteaga-Sanchez
UNLV Theses, Dissertations, Professional Papers, and Capstones
The fatalities, injuries, and property damage that result from traffic crashes impose a significant burden on society. Current research and practice in traffic safety rely on analysis of quantitative data from crash reports to understand crash severity contributors and develop countermeasures. Despite advances from this effort, quantitative crash data suffers from drawbacks, such as the limited ability to capture all the information relevant to the crashes and the potential errors introduced during data collection. Crash narratives can help address these limitations, as they contain detailed descriptions of the context and sequence of events of the crash. However, the unstructured nature …
The Parkinson’S Prison And The Hero’S Journey To Escape: Improvisation And Storytelling In Parkinson’S Disease, Robert David Cochrane
The Parkinson’S Prison And The Hero’S Journey To Escape: Improvisation And Storytelling In Parkinson’S Disease, Robert David Cochrane
UNLV Theses, Dissertations, Professional Papers, and Capstones
Parkinson’s disease (PD) is the fastest growing neurological disorder in the world, with leading researchers calling it a pandemic. While there is no cure, pharmaceuticals and surgical interventions increase people with Parkinson’s (PWP) ability to lead longer and more productive lives. However, there is a lack of care available for PWP supporting their social and emotional domains. PWP report high levels of stress, anxiety, and isolation due to the chronic and unpredictably progressive nature of the disease. This leads to a vicious cycle of loss of confidence, decreased activity and socialization, and increased falls.A common phrase in the PD community …

Effects Of Particle Size And Replacement Proportion Of Post-Consumer Glass In Concrete, Negasi Gebremichael
Effects Of Particle Size And Replacement Proportion Of Post-Consumer Glass In Concrete, Negasi Gebremichael
UNLV Theses, Dissertations, Professional Papers, and Capstones
Concrete, next to water, is the most used material (Gagg, 2014), which consumes natural or manufactured aggregates and resource-intensive cement. Concrete is also a more wasteful construction material than timber and steel. Depleting the natural resource due to aggregate extraction and the environmental unfriendliness of cement production have left the construction industry with no choice. Reducing waste, reusing, or recycling can help conserve natural resources. In this regard, the construction industry constantly seeks full or partial replacement of concrete aggregates and cement with recycled material. Glass is a candidate for replacing the three major components: cement, fine aggregate, and coarse …
A Mechanically Intelligent Hosing-Drone, Blake Hament
A Mechanically Intelligent Hosing-Drone, Blake Hament
UNLV Theses, Dissertations, Professional Papers, and Capstones
This manuscript presents a ”mechanically intelligent” approach to designing a Hosing-Drone for heavy-duty pressure washing. Spraying a hose creates strong reaction forces and torques. Previously demonstrated spraying robots are over-engineered to be very massive with huge inertias. These high inertias ”wash out” the reaction from the spraying. In the proposed approach, the contributions from all observable fluid dynamics, fluid structure interactions, and aerodynamics are studied individually and for the coupled system. Experimental data is collected and fit to dynamic models. These models are used to design a smaller, lighter, more agile vehicle than has been previously demonstrated. An impedance controller …

Toxoplasmosis, a zoonotic disease caused by the parasitic protist Toxoplasma gondii, is a ubiquitous, global public health concern with a wide variety of clinical manifestations. Surveillance for the disease is lacking even in developed countries, and what surveillance is present most often focuses on pregnant women. This research investigated trends in clinical toxoplasmosis in Nevada and nationally to address the lack of knowledge concerning how Nevada discharges compare to national discharges in cases of toxoplasmosis. Specifically, this research sought to determine what characterizes toxoplasmosis in Nevada across inpatient, outpatient, and emergency department settings, as well as how these cases differ …
Transformative Tourism Experience: Openness To Thriving, Solbi Lee
Transformative Tourism Experience: Openness To Thriving, Solbi Lee
UNLV Theses, Dissertations, Professional Papers, and Capstones
Over the last two decades, there has been growing academic rhetoric regarding the concept of transformation. Furthermore, the discussion of transformative experiences extends to the tourism industry and literature, reflecting the changing tourists' profiles and demands that challenge Destination Management Organizations (DMOs) to deliver tourist experiences that incorporate self-reflection and personal transformation. Transformative tourism experiences (TTE) (Soulard et al., 2021) refer to extraordinary encounters and episodes that prompt high emotional reactions that bring an opportunity to explore the self and significant inner personal changes. Despite the emerging academic and practical attention on TTE, research empirically testing the antecedents and outcomes …
Dimensionality Of Natural Auditory Scene Perception: A Factor Analysis Study, Margaret A. Mcmullin
Dimensionality Of Natural Auditory Scene Perception: A Factor Analysis Study, Margaret A. Mcmullin
UNLV Theses, Dissertations, Professional Papers, and Capstones
Theories of auditory and visual scene analysis suggest the perception of scenes relies on the identification and segregation of objects within it, resembling a detail-oriented processing style, but it is possible that a global-oriented process also occurs while evaluating auditory scenes. There is evidence for global properties that enable rapid recognition of visual scenes, even without recognizing the individual objects comprising the scene. It is our understanding that a similar line of research has not been explored in the auditory domain; therefore, we evaluated the contributions of high-level global and low-level acoustic information to auditory scene perception. A secondary aim …

UNLV Theses, Dissertations, Professional Papers, and Capstones
Purpose: This study aimed to identify potential factors associated with immediate postnatal care in Laotian women. Background: The World Health Organization recognizes that approximately half of all maternal deaths occur in the immediate postnatal period or 24 hours after birth. One crucial step to improving maternal mortality is a postnatal check during the first 24 hours following birth. Forty-seven percent of Lao women aged 15-49 who delivered a baby in the last two years received a postnatal health check in the first two days after delivery. Of these, 46.5% of postnatal checks were conducted prior to discharge from the facility …
Metabolic Syndrome And Associated Factors Among Hispanic Americans, Shannon L. Richard
Metabolic Syndrome And Associated Factors Among Hispanic Americans, Shannon L. Richard
UNLV Theses, Dissertations, Professional Papers, and Capstones
Metabolic syndrome (MetS) is a cardiometabolic condition that may develop into cardiovascular disease and type 2 diabetes mellitus. Early recognition and associated treatment of MetS can help detour disease. Lifestyle factors, sleep-disordered breathing, and psychological well-being influence the development of MetS; electrocardiogram abnormalities are associated with MetS. Hispanics living in the United States are particularly vulnerable to MetS. Although MetS is well-identified in Americans of Hispanic ethnicity, the current literature evaluating protective and contributory factors among Hispanic gender-ethnic subgroups is inconsistent and incomplete. This study aimed to examine the relationships between MetS and select health and lifestyle factors among seven …

Effects Of Patellofemoral Pain On Central Activation And Function Of The Gluteus Medius Muscle In Physically Active Females, Michelle Samuel
UNLV Theses, Dissertations, Professional Papers, and Capstones
Patellofemoral pain (PFP) is the most common knee injury among runners, military personnel, adolescents and recreationally active persons. PFP commonly presents as diffuse pain across the anterior knee that increases with activities such as running, squatting, and walking up and down stairs. Nearly 75% of patients with PFP either alter or completely stop physical activity as a result of the pain. There are numerous mechanisms that contribute to PFP symptoms; such as muscle weakness, abnormal joint mechanics and abnormal joint stress, which make it difficult to successfully treat. In addition, PFP may lead to patellofemoral joint (PFJ) osteoarthritis, a debilitating …

Examination Of The Relationship Between Loneliness And Binge Eating Symptoms, Kimberly Stevens
Examination Of The Relationship Between Loneliness And Binge Eating Symptoms, Kimberly Stevens
UNLV Theses, Dissertations, Professional Papers, and Capstones
Loneliness is implicated in several mental health conditions and may also be linked to eating pathology, like binge eating symptoms (e.g., loss-of-control eating). However, the pathways by which loneliness might be associated with binge eating symptoms are less well understood. Preliminary evidence suggests perceived stress may be a key explanatory pathway. Specifically, perceived stress mediates the impact of loneliness on other mental health outcomes and is associated with increased risk of binge eating symptoms. This study investigated relationships between loneliness, perceived stress, and binge eating symptoms and tested whether heightened levels of binge eating was accounted for by increases in …

Retrospective Varying Coefficient Association Analysis Of Longitudinal Binary Traits, Gang Xu
Retrospective Varying Coefficient Association Analysis Of Longitudinal Binary Traits, Gang Xu
UNLV Theses, Dissertations, Professional Papers, and Capstones
Many genetic studies contain rich information on longitudinal phenotypes that require powerful analytical tools for optimal analysis. Genetic analysis of longitudinal data that incorporates temporal variation is important for understanding the genetic architecture and biological variation of complex diseases. Most of the existing methods assume that the contribution of genetic variants is constant over time and fails to capture the dynamic pattern of disease progression. However, the relative influence of genetic variants on complex traits fluctuates over time.We developed several tests to fill the gap of analyzing time-varying genetic effects in longitudinal GWAS for binary traits. First, we propose a …
