Creating A Web Resource On Sense Of Belonging For Underrepresented Occupational Therapy Students In Graduate Programs, Owen Uyiosa Lawani
UNLV Theses, Dissertations, Professional Papers, and Capstones
Underrepresented students (URS) in graduate occupational therapy (OT) programs often struggle with a sense of not belonging due to a lack of representation in their cohort and curriculum. This has been evident among students who are from racial/ethnic backgrounds, first-generation college students (FGCS), and have had low-income experiences. Research has shown that a sense of belonging (SB) is important for URS' ability to cope with everyday stressors in higher education.This capstone project focused on developing a web-based resource addressing the perceived SB among URS in graduate OT programs. Data was collected from participants at the University of Nevada Las Vegas …

A Generalized Family Of Exponentiated Composite Distributions With Applications To Insurance And Survival Data, Bowen Liu
UNLV Theses, Dissertations, Professional Papers, and Capstones
The concept of composite distributions was proposed in the early 2000s as a good parametric solution to model the data with heavy tails. Since the concept was proposed, it has been widely used in different areas, such as modeling insurance claim size data, predicting the risk measures in insurance data analysis, fitting survival time data, and modeling precipitation data. While a lot of the composite distributions demonstrated great performances in real applications, many commonly used composite distributions such as the inverse gamma-Pareto (IGP) or exponential-Pareto (EP), did not demonstrate great performances when fitting to several particular data sets. In order …

Examining Reflexive Communication Following A Break In Alcohol Abstinence, Lynda Kay Maxfield
UNLV Theses, Dissertations, Professional Papers, and Capstones
Over 107 million individuals are thought to have alcohol use disorder (AUD) (Ritchie & Roser, 2018). Discontinuing drinking can be difficult, but social support is thought to promote sobriety efforts. The r/stopdrinking online public community supports such efforts. This study has two broad aims: (1) explore how resilience building might occur on r/stopdrinking among initial users disclosing an abstinence disruption and responses from other users; and, (2) explore possible relationships, within initial posts, between resilience and three other phenomena (i.e., trauma, stated views of Alcoholics Anonymous, statements reflecting the transtheoretical model’s ten processes of change; Prochaska & Prochaska, 2021). To …
The Influence Of Prediction Error Strength On Reconsolidation, Kevin D. Mohawk
The Influence Of Prediction Error Strength On Reconsolidation, Kevin D. Mohawk
UNLV Theses, Dissertations, Professional Papers, and Capstones
It has been well established that consolidated memories can be reactivated and enter a labile state where they are once again vulnerable to modification. Reactivated memories, therefore, need to be restabilized or reconsolidated. Prediction error (PE) is one of the most common ways of reactivating consolidated memories, yet no studies have examined how varying the strength of PE influences reconsolidation. The present study aimed to determine if the strength of PE is an important factor for triggering reconsolidation and if so, how PE strength influences the reconsolidation process, whether through strengthening or weakening the memory. To vary PE strength, participants …

“But What About Me?”: How Memorable Messages Received During Catholic Sex Education Contribute To The Development Of Identity Gaps, Hannah Novak
UNLV Theses, Dissertations, Professional Papers, and Capstones
Sex education in the United States is a widely debated issue. Christians have supported abstinence-based education in the United States for decades (Dent & Maloney, 2017). There are numerous studies that have examined how abstinence sex education is faulty, specifically religious sex education (Judge, 2020; Levand & Ross, 2021; Rasmussen, 2010; Reuther, 2008). Studies found that religious sex education led to mental, physical, and emotional health disparities in the United States (Baker et al., 2015; Nelson et al., 2017). This study explored how memorable messages received in Catholic sex education led to the formation of identity gaps in participants' lives. …

The Effect Of Sleep And Emotion On Pattern Separation, Alanna N. Osmanski
The Effect Of Sleep And Emotion On Pattern Separation, Alanna N. Osmanski
UNLV Theses, Dissertations, Professional Papers, and Capstones
Prior work on the relationship between sleep and memory suggests that the sleep state is an optimal time for memory consolidation to occur. During slow wave sleep, newly encoded information in the hippocampus is repeatedly activated, driven by slow oscillations that originate in the neocortex. This process that occurs during slow wave sleep facilitates the long-term storage of memories. A widely accepted view of emotion and sleep is that emotional memories are preferentially consolidated during sleep so that they are easily accessible for retrieval, whereas neutral memories tend to be less accessible. However, recent meta-analyses of sleep, emotion, and memory …

Systemic Theoretical Instruction: Tense And Aspect In Italian A Sociocultural Study Of American Learners Of Italian, Charles Joseph Panarella, Jr.
Systemic Theoretical Instruction: Tense And Aspect In Italian A Sociocultural Study Of American Learners Of Italian, Charles Joseph Panarella, Jr.
UNLV Theses, Dissertations, Professional Papers, and Capstones
University-level language and second-language classrooms typically use general rules of thumb to teach grammar without considering its conceptual aspects and cultural origins. These general rules of thumb are normally taught using a communicative approach to language teaching which typically places little emphasis on immediate corrective feedback and learner development. Most assessments are static in nature and focus on right and wrong answers rather than their origins (i.e., learner development and microgenesis). The lack of corrective feedback and lack of considering affective factors have the potential to negatively influence language acquisition in terms of motivation and self-efficacy. In addition, foreign language …
Comparing Comics And Illustrated Texts In Multimedia Learning, Jackson S. Pelzner
Comparing Comics And Illustrated Texts In Multimedia Learning, Jackson S. Pelzner
UNLV Theses, Dissertations, Professional Papers, and Capstones
The purpose of this research was to examine how different forms of media, in particular science comics and illustrated texts, contribute to different patterns of learning. While the standard illustrated text seen in a textbook has been a useful tool for instruction, science comics appear to be an alternative that could be used in lieu of media that use the traditional illustrated text format. The comic format, known more for its visual appeal to readers, is consistent with the principles of the Cognitive Theory of Multimedia Learning (Mayer, 2009), though comprehension may require different mechanisms (Cohn, 2013a). It was hypothesized …

Poop! There It Is! Anti-Germinants And Biological Variables As Modulators Of Clostridioides Difficile Infection (Cdi), Jacqueline Renee Phan
UNLV Theses, Dissertations, Professional Papers, and Capstones
Clostridioides difficile infection (CDI) is a major cause of antibiotic-associated diarrhea. Due to its insidious nature, the Centers for Disease Control and Prevention (CDC) has declared CDI an urgent threat. A key characteristic of C. difficile is its ability to form dormant spores that act as the infectious vehicles for disease. In the gut, spores recognize bile salts to germinate into toxin-producing cells.Dysbiosis of the gut microbiome is a key factor in allowing the C. difficile spores to germinate. Normal gut microbiota naturally protects from CDI. However, biological variables such as diet and sex have been found to modulate to …

Morphologic Comparisons Of Recrystallized And Neocrystallized Fibrous Amphibole Asbestos: Implications For Corresponding Health Risk Potential, Natalie G. Renkes
Morphologic Comparisons Of Recrystallized And Neocrystallized Fibrous Amphibole Asbestos: Implications For Corresponding Health Risk Potential, Natalie G. Renkes
UNLV Theses, Dissertations, Professional Papers, and Capstones
The presence of naturally-occurring asbestos (NOA) is increasingly concerning for scientists, health and regulatory agencies, and citizens living in impacted areas. It is commonly believed that fibrous amphibole asbestos can only form through neocrystallization. In southern Nevada, NOA occurs as a result of hydrothermal alteration of granitic rock producing fibrous amphibole both as cross-cutting neocrystallized veins and via recrystallization of original magmatic hornblende crystals. Fibers with a greater aspect ratio are known to have increased toxicity. This study measured the maximum length and average width of both neocrystallized and recrystallized fibers to see if the morphologies were similar. Neocrystallized and …
