Identification Of Factors Contributing To Traffic Crashes By Analysis Of Text Narratives, Cristian D. Arteaga-Sanchez Dec 2022

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 …

Beyond The Numbers: A Deeper Dive Into The Dearth Of Girls And Women In Stem, Jennifer John Buck Dec 2022

Beyond The Numbers: A Deeper Dive Into The Dearth Of Girls And Women In Stem, Jennifer John Buck

UNLV Theses, Dissertations, Professional Papers, and Capstones

Despite decades of research attempting to better understand the dearth of girls and women in science, technology, engineering, and math (STEM), gender imbalances persist in many STEM fields. This is particularly the case in math-intensive STEM fields. The current program of research used mixed-methods research to better understand these inequities. The first paper identified gender and ethnic variation in how undergraduates reason about STEM inequities. The second paper found that how emerging adults narrate “turning points” in their relationship with math was associated with their current math outcomes and future plans to pursue math. The final paper demonstrated that how …

Hydrogeologic Heterogeneity Identification: Using Inverse Modeling Of Synthetic Borehole Temperatures To Predict Groundwater Flux, Kevin Heintz Dec 2022

Hydrogeologic Heterogeneity Identification: Using Inverse Modeling Of Synthetic Borehole Temperatures To Predict Groundwater Flux, Kevin Heintz

UNLV Theses, Dissertations, Professional Papers, and Capstones

Heat has been effectively used as a groundwater tracer for decades, and high-resolution temperature data can better identify and quantify discrete flow zones. Refinements to the numerical modeling of advective heat transfer in borehole temperature sensing deployments can improve understanding of dynamic hydrogeologic systems. In my thesis, I develop a novel two-dimensional coupled radial groundwater flow and heat transfer numerical model that considers intra-borehole vertical flow. To test the performance of this model, I used finite element analysis to generate synthetic data sets consisting of prescribed variable flow fields and resulting borehole temperatures. I input synthetic temperatures into the two-dimensional …

Calcite Spherulite Formations And Their Controls In Halophilic Bacterial Cultures, Zakaria Jibrin Dec 2022

Calcite Spherulite Formations And Their Controls In Halophilic Bacterial Cultures, Zakaria Jibrin

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study arose from an accidental discovery of calcite spherulites forming on colonies of various halophilic bacteria grown on solid Luria-Bertani medium made containing water from a brine pool in Death Valley, their natural habitat. Further studies with a large spherulite forming bacteria, Pseudoalteromonas haloplanktis, showed that calcite precipitation conditions were the consequence of bacteria using amino acids as a source of carbon and energy, a metabolism that produces NH3 and CO2 waste products. NH3 raises the pH of the medium, turning CO2 into CO32-. Calcium in the natural brine combines with CO32-. The resulting spherulitic calcite precipitation is nano-acicular …

Disentangling Instrumental And Reactive Aggression In The Competitive Reaction Time Task And Their Associations With Factors Of Meanness In Psychopathy, Ashley Michelle Poston Dec 2022

Disentangling Instrumental And Reactive Aggression In The Competitive Reaction Time Task And Their Associations With Factors Of Meanness In Psychopathy, Ashley Michelle Poston

UNLV Theses, Dissertations, Professional Papers, and Capstones

Aggression is often subtyped into reactive and instrumental aggression. Reactive aggression occurs in response to some form of provocation and is often accompanied by anger. Instrumental aggression is not provoked and is relatively unemotional. Existing aggression paradigms primarily measure reactive aggression, and the laboratory measurement of instrumental aggression has proved challenging. This study modified the competitive reaction time task to include an entire block of instrumental aggression trials, in addition to the standard block of reactive trials, in effort to create a single paradigm within which both reactive and instrumental aggression can be measured in the laboratory. Psychopathy is a …

Metabolic Syndrome And Associated Factors Among Hispanic Americans, Shannon L. Richard Dec 2022

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 …

Mesozoic Sevier Thrusts Overprinted By Miocene-Quaternary Left-Lateral Deformation: Structures And Tectonism Of The Kane Springs Wash Region, Nevada, Andrew Reid

UNLV Theses, Dissertations, Professional Papers, and Capstones

Recognizing how rifts develop through space and time is vital to enrich our understanding of continental breakup. Rifts are commonly segmented by transfer or accommodations zones that form as the rift develops due to differences in the onset, direction, magnitude, or rates of extension on either side of the transfer or accommodation zone. The Basin and Range province is a wide rift where Cenozoic extension overprints and exposes earlier Mesozoic Sevier fold-thrust belt shortening structures. This exposure allows Sevier thrust correlations between individual mountain ranges and use of these shortening structures to study rift segmentation by strike-slip transfer faults. The …

The Model Minority Myth And The Mental Well-Being Of Academically Struggling Asian Americans, Jan Michael Roa Ballesteros Dec 2022

The Model Minority Myth And The Mental Well-Being Of Academically Struggling Asian Americans, Jan Michael Roa Ballesteros

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation investigates relationships between pressures Asian Americans experience to be academically successful and their feelings of depression and stress. The model minority myth (MMM) stereotype characterizes Asian Americans as industrious, intellectually-gifted, assimilating to U.S. values of meritocracy, and achieving higher academic and employment success levels compared to other racial groups in the general population. While many consider MMM a positive stereotype, it also comes with a cost. Prior research demonstrates the tensions that exist among Asian Americans who do not uphold the MMM stereotype and its corollary, the Asian Academic Success Frame. Those unable to meet academic success standards …

Comparing Forgetting Rates Between Pattern Separation And Item Recognition, Rhiannon N. Soriano Smith Dec 2022

Comparing Forgetting Rates Between Pattern Separation And Item Recognition, Rhiannon N. Soriano Smith

UNLV Theses, Dissertations, Professional Papers, and Capstones

Recent theories of forgetting posit that hippocampally-based memory representations are more prone to be forgotten due to decay, while extra-hippocampal representations are more likely to be forgotten due to interference (Hardt, Nader, & Nadel, 2013; Sadeh & Pertzov, 2020). The current study examined this hypothesis by comparing the rate of forgetting between pattern separation, a hippocampally-based process, and item recognition, a process that is reliant on both hippocampal and extra-hippocampal structures. It was hypothesized that pattern separation would display more forgetting due to decay because it is a hippocampally-based process, while item recognition would display more forgetting due to interference …

Jiapi: A Type Checker Generator For Statically Typed Languages, Benjamin Cisneros Merino Dec 2022

Jiapi: A Type Checker Generator For Statically Typed Languages, Benjamin Cisneros Merino

UNLV Theses, Dissertations, Professional Papers, and Capstones

Type systems are a key characteristic in the context of the study of programming languages. They frequently offer a simple, intuitive way of expressing and testing the fundamental structure of programs. This is especially true when types are used to provide formal, machine-checked documentation for an implementation. For example, the absence of type errors in code prior to execution is what type systems for static programming languages are designed to assure, and in the literature, type systems that satisfy this requirement are referred to as sound type systems. Types also define module interfaces, making them essential for achieving and maintaining …

Examination Of The Relationship Between Loneliness And Binge Eating Symptoms, Kimberly Stevens Dec 2022

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 …
