Background: We examined interactive effects of sex, diagnosis, and cerebrospinal fluid (CSF) amyloid beta/phosphorylated tau ratio (Aβ/P-tau) on verbal memory and hippocampal volumes. Methods: We assessed 682 participants (350 women) from BioFINDER (250 cognitively normal [CN]; and 432 symptomatic: 186 subjective cognitive decline [SCD], 246 mild cognitive impairment [MCI]). General linear models evaluated effects of Alzheimer’s disease (AD) proteinopathy (CSF Aß/p-tau ratio), diagnosis, and sex on verbal memory (ADAS-cog 10-word recall), semantic fluency (animal naming fluency), visuospatial skills (cube copy), processing speed/attention functions (Symbol Digit Modalities Test and Trail Making Part A), and hippocampal volumes. Results: Amyloid-positive (Aβ/P-tau+) CN women …

A Retrospective Survey Of Exercise Habits In Low-Income Female Senior Citizens, Kelly L. Bumgarner

UNLV Theses, Dissertations, Professional Papers, and Capstones

American adults spend at least 50% of their time sedentary with the most inactive demographic being low-income women over 60. This is detrimental because routine physical activity benefits for senior women include balancing hormones, maintaining bone mineral density, and decreasing the risk of breast cancer. Statements like “good exercise habits begin during youth; children should play sports to establish healthy habits they’ll continue throughout their lives” are common, but not clearly supported by literature. Objective: The purpose of this retrospective, cross-sectional study was to identify whether physical activity/exercise habits during youth and young adulthood predict old age physical activity/exercise habits …

Uncovering The Women In Ocean’S Eight: Understanding The Trends Of The Women’S Movement With The Portrayals Of Women In Film, Elyssa Michelle Day

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study seeks for a better understanding of the correlations between major milestones in the women’s movement and how that is reflected onto the silver screen. With the rise of sexual assault allegations against prominent figures in Hollywood, and the growth of the #MeToo movement, we in turn are beginning to see an influx of films being released, and older films being rebooted, with an all-female led cast. One of those all-female film reboots is Ocean’s Eight, a film coming from a male-dominated trilogy and genre. Because of this correlation, the question of whether the narratives within Ocean’s Eight reinforce …

Empirical Justification For Supportive Other Involvement In Collegiate Athletes’ Mental Health Intervention, Elena Gavrilova

UNLV Theses, Dissertations, Professional Papers, and Capstones

Student-athletes have been identified to evidence similar or higher rates of mental health difficulties and lower levels of mental health engagement as compared with non-athlete peers. Along these lines, sport-specific mental health intervention has been justified by researchers, yet only one randomized clinical trial has been conducted in collegiate student-athletes who have been formally assessed for mental health disorders (i.e., a family behavior therapy as compared with traditional campus counseling as usual; Donohue et al., 2018a). Results of this outcome study demonstrated greater improvements for participants who received the family-based intervention up to 8-months post-randomization. In this clinical trial, the …

The Impact Of Virtual Presence On Willingness To Book: The Moderating Role Of Self-Construal And Gender, Sung Jun Joe

UNLV Theses, Dissertations, Professional Papers, and Capstones

Social influence is not limited only to interactive situations but also includes those that occur without a direct interaction such as the mere presence of others (Argo, Dahl, & Manchanda, 2005). Although there is wide agreement that the mere presence of others influences one’s decision-making process, little research is conducted to understand whether the effect of the presence of others influences consumer behaviors in an online context (Naylor, Lamberton, & West, 2012). To address this gap, this study suggests that mere virtual presence (MVP) provides social cues to the customer and influences the customer’s willingness to book (WTB). Specifically, the …

Consequences Of Math Anxiety And Stereotype Threat: An Intersectional Perspective, Jennifer E. John Buck

UNLV Theses, Dissertations, Professional Papers, and Capstones

Individuals with science, technology, engineering, and math (STEM) skills are highly valued for their contribution to the U.S. workforce and society. However, women and some people of color enter STEM fields at lesser rates than do White men. Math anxiety and stereotype threat have been found to cause math performance decrements for women and some people of color. Presently, it is not clear how math anxiety and stereotype threat might work together to dually influence math performance and subsequent STEM participation. The current study focuses on a diverse sample of 295 undergraduate students who were randomly assigned to one of …

A Binding Sisterhood Of Transnational Feminism: A Close Look At Iran And Argentina, Bernadette Mary Lazar

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation examines the impact of transnational feminism in Iran and Argentina. Specifically, it focuses on the role of the diaspora and international communities and their interactions with social movements in these two countries. Although the study of transnational feminism is not a new phenomenon, very little research has been dedicated towards distinguishing the effects and differences in outcomes when either the diaspora or the broader international network is involved. By filling this gap in the literature, this dissertation will shed light on whether the diaspora community, NGOs, or the international community is necessary for success or favorable outcomes in …

The Effects Of Background, Classroom Assessment Competence, Self-Efficacy, And Self-Perceived Assessment Skills On Classroom Assessment Practices Of Teachers In India, Manognya Murukutla

UNLV Theses, Dissertations, Professional Papers, and Capstones

Teacher-conducted assessments are necessary to gather important information to facilitate student learning and academic success. Unfortunately, there is an inconsistency in teacher knowledge of assessment and assessment practices. While previous research identified a gap in teacher competence and teacher perceptions of their competence, and this affects classroom assessment practices that then impact student learning, the research is limited, outdated, and not grounded in any theoretical framework. This study addresses gaps in literature and establishes self-efficacy as a theoretical framework in which classroom assessment can be studied. Data were collected in India, and a path analysis and a Kruskal Wallis non-parametric …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The strategic planning objectives for a novel Bike Sharing Systems (BSS) are to locate the BSS stations, size the stations, and determine the bicycle fleet size, among others. Current guidelines to design BSS programs are tailored to city centers with large coverage areas and high bicycle to population ratios, and thus not directly transferable to a university setting. An ordered probit model was created using data from a university online stated preference survey to determine the key factors that affect the uptake rates for the UNLV BSS program and to estimate the potential demand. The demand analysis was incorporated into …

Chatting Online: An Ethnographic Case Study Of Educator Discourse On Social Media, Lindsay J. Russell

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study sought to examine the online discussions of teachers located in the Southwestern area of the United States regarding social justice issues on social media. Specifically, it looked to discover how educators in this region are attempting to assert agency when faced with socially inequitable situations. Teachers in this region are hired as public employees in a state that penalizes public workers for exhibiting opinions (SRS § 288.260, 1969).

The study utilized Cultural Historical Activity Theory along with Critical Multiculturalism to demonstrate that our present actions are culturally and historically situated while illuminating hegemonic forces. The study found that …

International Faculty’S Lived Experience Of Teaching: A Multiple-Case Study Of Taiwanese Professors In The United States, Ching Hsu Kim

UNLV Theses, Dissertations, Professional Papers, and Capstones

In the context of higher education, a tenure-track faculty is expected to be actively engaged in scholarly activities including research, teaching and service activities. Finding a balance between personal and career lives is seen critical yet challenging especially to early-career international faculty members while they are in the face of differences and changes. Framed by theories of perezhivanie and resilience, the study examined international faculty members’ lived experiences of teaching. Interviews, blog prompts and reflection prompts were used to identify their major difficulties, perceptions and adjustments, and resilience development.

Blanche Dubois: A Woman's Journey From Belle Reve Through Tarantula Arms To The Elysian Fields, Raluca Daniela Comanelea

UNLV Theses, Dissertations, Professional Papers, and Capstones

This present thesis aims at deconstructing the main character of A Streetcar Named Desire by Tennessee Williams: Blanche DuBois. Blanche’s journey is traced from Death to Desire and finally, to an ultimate envisioned destination, The Elysian Fields, which represents her physical and spiritual burial at sea, with her soul ultimately reaching heaven. Blanche’s most important quality - her ability to seduce audiences into perceiving the multifaceted layers of her feminine character all at once - marks her entry into Williams’s theatre of excess. Her theatricality springs precisely from her fascinating ability to reconstruct her persona in the course of the …

Improving Community College Students' Interest, Utility-Value, And Performance: How Does Future Time Persective Influence A Utility-Value Intervention?, Elsa Maria Mason

UNLV Theses, Dissertations, Professional Papers, and Capstones

The economic benefits of academic success and completion are long-lasting. Students who attend community colleges can stand to benefit a great deal by completing a 4-year degree or even a 2-year degree. Unfortunately, these students often begin their higher education journey not fully prepared for college-level coursework. Students often fail to see how their college coursework relates to their lives and in turn, don’t hold interest or perceive value for the course and consequently do not perform well. Using Eccles et al. (1983) expectancy-value theory this study tested how community college students would respond to a utility-value intervention in which …

Meal Duration: Implications For Restaurant Revenue Management, Dale F. Billings

UNLV Theses, Dissertations, Professional Papers, and Capstones

A comprehensive revenue management strategy addressing space, product, price and time, has been shown to increase profits within the hospitality sector. While the literature shows that the restaurant industry has frequently addressed space, product, and price when looking at financial strategy, the effect of the variable of time on revenue generation has not been adequately studied. Restaurants shy away from the practice of using time as a commodity, particularly regarding meal duration, due to fears of reducing customer satisfaction.

This project explores the use of time as a commodity in restaurant revenue management. In particular, it examines consumers’ feelings about …

On Improving Performance Of The Binary Logistic Regression Classifier, Michael Chang

UNLV Theses, Dissertations, Professional Papers, and Capstones

Logistic Regression, being both a predictive and an explanatory method, is one of the most commonly used statistical and machine learning method in almost all disciplines. There are many situations, however, when the accuracies of the fitted model are low for predicting either the success event or the failure event. Several statistical and machine learning approaches exist in the literature to handle these situations. This thesis presents several new approaches to improve the performance of the fitted model, and the proposed methods have been applied to real datasets.

Transformations of predictors is a common approach in fitting multiple linear and …

Disparities In Administrative Pediatric Asthma Prevalence In Clark County, Aaliyah Goodie

UNLV Theses, Dissertations, Professional Papers, and Capstones

Objective: Asthma is one of the most common chronic diseases affecting young children nationally and globally. Asthma affects more than 25 million people in the nation, of which 6

million are children. Lifetime asthma prevalence for children in Nevada is 11.5% (CDC, 2016). This is likely an underestimate due to a large undocumented Hispanic population. In Clark County School District (CCSD) during the 2016-2017 school year, 20,235 students (8%) listed asthma in school records as a health concern. Asthma burden varies by sociodemographic group with highest rates documented among Black/African American, Hispanic/Latino, and pediatric populations. The Centers for Disease Control …

Lifting The Veil: Do Health Care Price Transparency Laws Actually Lower Costs?, Nora Michelle Irene Langendorf

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this research is to determine whether or not health care transparency laws, in the form of price transparency, lower the rate of increase paid out in health care expenditures in those states that have enacted these laws compared to those states that have not. By controlling for factors such as poverty, age, chronic illnesses, and income that may play a part in lowering or raising health care costs, the primary explanatory variable – health care price transparency laws – can determine if there is a strong relationship with the dependent variable (the rate of increase on health …

The Symbolism Of Play Behavior In Child-Centered Play Therapy, Kaitlin Andrewjeski

UNLV Theses, Dissertations, Professional Papers, and Capstones

Child-Centered Play Therapy (CCPT) is an evidence-based approach for mental health treatment with children. CCPT is based on the belief that play is a child’s natural language and so the therapist is required to make inferences of themes through observations of free play; however, there is no standard process by which themes are identified. The purpose of the current study is to gain detailed descriptions of play behavior in order to describe how themes emerge and how they are displayed in child-centered treatment. The themes were then used to describe the progression through the typical stages of child-centered play therapy. …

Should We Flip The Script?: A Literature Review Of Deficit-Based Perspectives On First-Year Undergraduate Students’ Information Literacy, Tatiana Pashkova-Balkenhol, Mark Lenker, Emily Cox, Elizabeth Kocevar-Weidinger

Library Faculty Publications

This mixed method systematic review considers recent literature on the information literacy (IL) skills of first-year undergraduate students. The review uncovers the following themes: faculty and librarians perceive first-year students as lacking IL skills; students have varying perceptions of their IL skills; assessment studies yield conflicting findings on first-year students' IL; communication between high school and college librarians is challenging; and some IL researchers emphasise and leverage first-year students' prior knowledge and experience in IL instruction. These themes emerge from extensive searches in four research databases for scholarly and professional articles written in English within the past ten years. With …

Participants with high school/GED or higher …

Reframing Library Student Employment As A High-Impact Practice: Implications From Case Studies, Erin Rinto, Rosan Mitola, Kate Otto

Library Faculty Publications

The purpose of this paper is to discuss how academic libraries can directly contribute to campus student success initiatives through student employment programs. Case studies from the perspectives of two supervisors demonstrate how library student employment programs can intentionally incorporate the characteristics of High-Impact Practices. This paper builds upon a previously published systematic review of the academic library literature on student employment, which found a significant gap in the discussion of employment as a mechanism for learning and retention. This paper aims to address this gap by focusing on practical applications for creating more learner-centered student employment programs.
