Transforming Fear Of Falling Care: Bridging Evidence Synthesis And Clinical Trial On Cognitive Behavioral Therapy-Based Multicomponent Interventions For Older Adults, Haehyun Lee

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction: Fear of falling (FoF) and associated avoidance behavior represent critical health concerns for older adults, with profound impacts on physical functioning, independence, psychosocial well-being, and healthcare utilization. Although fear of falling avoidance behavior (FFAB) is increasingly recognized as a distinct construct and clinically meaningful construct, intervention research remains limited due to fragmented assessment methodologies and incomplete integration of cognitive-behavioral and physical approaches. This dissertation addresses these gaps through two interrelated projects (1) a scoping review of the evidence base, assessment methods, and intervention strategies for Cognitive Behavioral Therapy (CBT) targeting FFAB in older adults; and (2) a randomized controlled …

A Mixed Methods Study Of Teacher Job Satisfaction And Principal Support In Private Jewish Day Schools Through The Lens Of Self-Determination Theory, Abigail E. Moyal

UNLV Theses, Dissertations, Professional Papers, and Capstones

This mixed methods study investigated how principal support influences teacher job satisfaction in private Jewish day schools through the lens of Self-Determination Theory (SDT). SDT asserts that motivation and well-being depend on the fulfillment of three basic psychological needs: autonomy, competence, and relatedness. Using an explanatory sequential design, quantitative data were first collected from 68 teachers across five Jewish day schools in the Southwestern United States using the Teaching and Learning Survey (TALIS) Teacher Job Satisfaction Scale (TJSS) and the Principal Support Scale (PSS). Results showed moderate to high satisfaction levels and a strong positive correlation between principal support and …

Characterization Of The Electronic Structure Of Metal–Organic Framework Mil-125 And Its Derivatives Using Soft X-Ray Spectroscopies, Jennifer Alexia Napoles

UNLV Theses, Dissertations, Professional Papers, and Capstones

Metal–organic frameworks (MOFs) are highly porous, three-dimensional networks composed of coordinated metal clusters and organic ligand subunits. While tens of thousands of MOFs have been synthesized, the Ti(IV)-based MOF MIL-125 has garnered scientific interest due to the observed changes to its optical and photocatalytic properties upon chemical modification. For example, upon UV irradiation in the presence of an alcohol, MIL-125 undergoes a photochromic color change to a photodoped state that has been associated with the storage of charge in the form of Ti(III) sites. Another example is exemplified by the amine group functionalization of the 1,4-benzenedicarboxylate (BDC) linker of MIL-125 …

Design And Development Of Biomimetic Hydrogel Interfaces For Enhanced Bioelectrical Signal Acquisition, Daniela Nikoloska

UNLV Theses, Dissertations, Professional Papers, and Capstones

Every second, human skin processes over one million sensory signals while maintaining properties such as electrical conductivity, mechanical adaptability, and regenerative capability that surpass all synthetic materials. Contemporary bioelectronic devices prove inadequate when contacting skin surfaces due to poor adhesion and electrical contact issues that prevent effective sensing. Despite advancements in wearable and bioelectronic technologies, current devices face major drawbacks when interfacing with human skin, particularly in maintaining firm adhesion, conformability, and low-noise electrical signal acquisition.

This research focuses on the development of a biomimetic hydrogel-based interface for bioelectronic sensing. Specifically, a hybrid hydrogel system composed of polydopamine (PDA)- doped …

Platforms, Privacy, And Power: Examining Predictors Of Online Intimate Information Disclosure And Expression, Alexis Shore Ingber, Danielle Keats Citron, Jonathon W. Penney

Articles & Book Chapters

When intimate privacy is violated, self- and relational development is impaired to the detriment of individuals and society. Despite these costs, there is a lack of systematic empirical and theoretical study of intimate privacy and efforts to protect it. This research helps fill this void through two complementary studies. Through a longitudinal experimental design, results from Study 1 highlight that partner trust and response-efficacy were not only positively predictive of online intimate disclosure, but also strengthened following knowledge of intimate privacy protections. In Study 2, we find individuals are more likely to engage in public-facing online sexual expression if the …

This exploratory survey sought to examine how faculty have introduced IL skills to students before, during, and after the COVID-19 lockdowns. After returning to in-person operations in 2021, the authors observed a change in how faculty have engaged with libraries to teach IL to their students. Methods - Utilizing parallel survey instruments, we asked faculty and librarians for their perceptions of current …

Teachers’ Emotional Appraisals And The Reframing Of Student Change In Post-Pandemic Schools, Rachel Gaines, Mei-Lin Chang, Kristen Mosley

Faculty Articles

Introduction:

The return to “normal” schooling after the COVID-19 pandemic reactivated many of the emotional, instructional, and moral tensions teachers experienced during emergency remote teaching. Yet, little is known about how teachers’ emotional appraisals of post-pandemic classrooms intersect with deficit-oriented “learning loss” discourses. Guided by appraisal theory and Frenzel’s reciprocal model of teacher emotions, this qualitative study examined how mid- and late-career teachers interpreted perceived changes in students and how these appraisals shaped their emotions, emotion regulation, and adoption of or resistance to deficit framings.

Methods:

Ten K–12 teachers from the southeastern United States participated in semi-structured interviews. Data were …

Methylation-Based Signature To Distinguish Indolent And Aggressive Prostate Cancer, Muheng Liao, Jace Webster, Amy Ly, Emily Rozycki, Christopher A Maher

2020-Current year OA Pubs

Prostate cancer management faces significant challenges in distinguishing indolent from aggressive disease, particularly since most patients are intermediate-risk and therefore hinders the ability to recommend standardized treatment recommendations. Moreover, current prognostic tools including Gleason scoring and tumor staging demonstrate limited accuracy for predicting disease progression and tumor recurrence. DNA methylation serves as a stable epigenetic modification that directly regulates gene expression, making it an ideal biomarker for cancer prognosis. Therefore, this study leveraged whole-genome enzymatic methylation sequencing on 120 patients to develop a novel prognostic signature for aggressive prostate cancer progression. We analyzed 20,849 differentially methylated regions (DMRs) and employed …

Opinions Of The Uk General Public And Stroke Survivors In Using Artificial Intelligence And ‘Opt-Out’ Models Of Consent In Medical Research: A Qualitative Study, William Heseltine-Carp, Mark Thurston, Michael Allen, Daniel Browning, Megan Courtman, Aishwarya Kasabe, Emmanuel Ifeachor, Stephen Mullin

Peninsula Medical School

Background Artificial intelligence (AI) in healthcare often requires large, confidential clinical datasets. However, a recent UK government survey revealed that 20–40% of the public remain sceptical of its use in health research due to concerns about data security, patient–practitioner communication and commercialisation of data. A greater understanding of public attitudes is therefore needed, particularly in the context of stroke research.In this article, we describe the patient and public involvement work undertaken for the AI-Based-Stroke-Risk-fActor-Classification-and-Treatment (ABSTRACT) project, which aims to train AI models to predict future stroke risk from the electronic health records of 1 18 736 patients.Aims We aimed to …

Pronatalism In The United States: How Political Ideals Surrounding Family And Reproductive Health Care Contribute To Neglect In The Foster Care System, Carson Sebree

Undergraduate Honors Theses

Within the past decade, conservative reproductive politics in the United States have experienced an ideological shift from pro-life toward pronatalism. This has been intensified through the rollback of reproductive rights and the rise of Christian nationalism. However, there has been no commensurate additional funding for the foster care system. This project asks the interrelated questions of: “how is pronatalism linked to neglect within the foster care system?; and, how do theories of democratic care highlight the necessity to rethink support for the foster care system and create policies that will address its shortcomings, given the rise of pronatalist aw and …

Latino Economic Inequality In New York City: Income And Snap Recipiency, 2013–2023, Oswaldo A. Mena Aguilar

Center for Latin American, Caribbean, and Latino Studies

This Latino Data Project Report analyzes trends in the economic well-being of Latino households in New York City between 2013 and 2023, focusing on household income and participation in the Supplemental Nutrition Assistance Program (SNAP). The findings reveal a paradoxical pattern: although median Latino household income increased over the decade, economic inequality within the Latino community widened substantially. Income gains were unevenly distributed, with higher-income households pulling further ahead while the lowest-income households experienced stagnation or decline. Over the same period, Latino households fell further behind all other racial and ethnic groups in the city. Additionally, Latinos consistently exhibited the …

The Effects Of Educational Materials On Knowledge And Attitudes Toward Psilocybin, Lindsey Elise Wade

Master's Theses

Depression is one of the most prevalent and burdensome mental health conditions worldwide, affecting millions and contributing to over 700,000 deaths by suicide annually. Nearly half of patients with major depressive disorder fail to respond adequately to standard antidepressant treatments such as selective serotonin reuptake inhibitors (SSRIs). Psilocybin-assisted therapy (PAT) has emerged as a promising alternative for treatment-resistant depression (TRD), yet public understanding of this therapy remains limited. The present study examined whether a brief psychoeducational intervention could affect knowledge and attitudes toward PAT among members of the general public in the United States. Participants were randomly assigned to read …

Fabrication Of Three-Dimensional Seaweed-Based Scaffolds And Evaluation Of Cell Attachment And Viability For Cultured Meat Applications, Srishti Tandon

Honors Scholar Theses

Global demand for animal protein is increasing rapidly, underscoring the need for sustainable meat production. Cultured meat is a promising alternative to traditional meat production techniques, but it requires optimization before it can be implemented on a large scale. Scaffolds are an important component for making cultured meat, as they provide structural support for cell attachment and mimic the texture of meat. Scaffolds need to be biocompatible, mechanically supportive, and biochemically active to promote proper cell adhesion, proliferation, and differentiation. This project investigated brown seaweed extract (SWE) hydrogels as a scaffold for cultivated meat applications and compared their mechanical and …

Urban Shadows In Latin America: Detection Of Crime Hotspots Using Multivariate, Geospatial, And Neutrosophic Analytic Hierarchy Process (Nahp) Analytical Techniques, Johnny Pambabay-Calero, Sergio Bauz-Olvera, Oscar Scott-Macías, Pedro Luzuriaga Cedeño, Purificación Galindo-Villardón

Neutrosophic Sets and Systems

In recent years, Guayaquil fell prey to higher levels of organized extortion compared to territorialized criminal organizations over territory, institutional weaknesses, and socio-spatial inequalities. Thus, while extortion emerged as an increasingly specialized crime, there are limited empirical studies to evaluate the crime's spatiotemporal nature or its determinants. Therefore, this study aims to identify and characterize extortion "criminal severity zones" of Guayaquil from 2021-2024, via a novel geostatistical approach, in addition to the Neutrosophic Analytic Hierarchy Process (NAHP). By implementing Exploratory Spatial Data Analysis (ESDA), Kernel Density Estimation (KDE), dimensionality reduction techniques (PCA, MDS, and t-SNE), hierarchical clustering, and Bayesian hierarchical …

Identification Of Gaps In Ecuadorian Inclusive University Education Through Plithogenic Offsets, Genesis Carmen Alcívar Junco

Neutrosophic Sets and Systems

Although Ecuador has made strides in regulation, the barriers to inclusive universities reveal a fragmented vision for access and non-termination of special educational needs (SEN) persons. This research aims to assess the impact of physical, academic, and political-institutional barriers on successful inclusion. The importance of this study stems from the need to promote equality in education, a fundamental trait in equitable and fair societies where an increasingly diverse population renders diversity a value. Scholars note barriers regarding spaces and human resources; however, few touch upon the ambiguity and uncertainty of perceptions from all educational stakeholders. Thus, a mixed-method design approach …

Theses and Dissertations

Plant preservation, whether through disease research or endemic extinction analyses, plays an important role in the relationship between humans and our surrounding environment. In these analyses, both the role of mobile elements in the evolution of pathogenic Xanthomonas sp. bacteria, and the demographic and reproductive analysis of Castilleja parvula, an imperiled alpine plant, are evaluated. Xanthomonas species are one of the top agricultural threats, and are known to evolve rapidly. Until now, the contributions of mobile elements and particularly bacteriophage have not been thoroughly evaluated. The contribution of these agricultural diseases to food insecurity and the devastation of crops that …

Understanding Crime Through Harm: A Multi-Stage Study Of Rochester, Ny, Hayder Alhafedhi

Theses

This capstone project develops, critiques, and applies a Crime Harm Index (CHI) for the City of Rochester, New York, as an alternative to traditional crime measures that rely solely on raw counts. Rather than treating all offenses as equal “one crime = one unit,” the project weights crimes by the severity of harm they cause, using New York State sentencing guidelines as the core metric. Across four working papers, the project moves from conceptual foundations and limitations of harm-based metrics, to the construction of a Rochester-specific Crime Harm Index, and finally to a set of spatial regression models that link …

Understanding The Relationship Between Mental Health And Criminal Justice Involvement: Pathways, Disparities, And Improving System Responses, Haley Bly

Theses

This capstone project examines the complex relationship between mental health and involvement in the criminal justice system, emphasizing how pathways, external conditions, structural inequities, and system responses interact to shape long-term outcomes for persons with mental illness (PwMI). While mental illness alone is not a predictor of criminal behavior, the intersection between psychological disorders, social strain, stigma, and systemic failures significantly heightens the risk of criminal justice involvement. Combining four working papers, this capstone examines these relationships across individual, environmental, institutional, and community levels, ultimately arguing that treatment and rehabilitative-centered reforms are essential for improving the experiences of individuals with …
