Beyond Work-Family Conflict: Conceptualization And Measurement Of Work-Eldercare Conflict, Patrick Cullen

Electronic Theses, Projects, and Dissertations

The number of workers with informal caregiving responsibilities continues to grow exponentially (Feinberg & Skufca, 2020), yet research on the intersection of work and eldercare is often neglected in the literature (Griggs et al., 2020). While earlier eldercare measures have typically been dichotomous, researchers have more recently begun to incorporate multidimensional measures of eldercare (Calvano, 2013). However, what has yet to be thoroughly explored is eldercare in the context of role theory, particularly interrole conflict, as existing work-family measures may be deficient in this regard. Therefore, in the present study, role theory was used to develop the Work-Eldercare Conflict Scale …

Sediment And Debris Flows Resulting From The 2020 El Dorado Wildfire, San Bernardino Mountains, California, Andrew Suarez

Electronic Theses, Projects, and Dissertations

The Yucaipa Ridge is a section of the San Bernardino Mountains within the Transverse Ranges of Southern California. During the summer and early fall of 2020, Yucaipa Ridge experienced severe vegetation damage from both the Apple and El Dorado wildfires. Burned slopes exhibit a higher susceptibility to geomorphic change within several years of burning from the introduction of meteoric water onto the slope. Yucaipa, Oak Glen, and other nearby communities are currently at risk of damage by hyperconcentrated flows and debris flows during the seasonal rainy season.

Debris flows and hyperconcentrated flows (a.k.a. mudflows; are grouped and referred to in …

Geochemistry Of The Inyo Volcanic Chain, And Evaluation Of The Portable Niton Xrf Instrument, Dylan Terry

Electronic Theses, Projects, and Dissertations

The Inyo Volcanic Chain (IVC) is a series of rhyolitic lava domes straddling the northwest rim of the Long Valley Caldera (LVC), most recently erupting ~650 years ago, producing the South Deadman, Obsidian, and Glass Creek Domes. For this study, samples were analyzed for geochemistry and petrography at six of the IVC domes. To measure geochemistry, a portable x-ray fluorescence machine (PXRF) was used, in part to test how well it performed on felsic rocks. The PXRF performed poorly with the factory calibration in detecting most elements, though detection of some elements improved with a calibration curve applied. The three …

These Things Happen, Keleigh E. Mcmullen

Electronic Theses, Projects, and Dissertations

My artwork emerges from moments of emotional and physical violence—both small and large. Although rooted in my lived experience, the truths I tell in my work are far from unique. Violence often hides in plain sight, buried in the mundane spaces of daily life. Through ceramic sculpture, I spotlight these moments, inviting viewers into a world that is familiar and simultaneously unsettling.

Scale plays a crucial role in this narrative—objects shrink or expand based on their emotional gravity, their object authority, or my own relationship to them. By amplifying the small and shrinking the overwhelming, I reshape how viewers interact …

Does It Burn Yet?, Antonia L. Rodriguez

Electronic Theses, Projects, and Dissertations

My photographic practice emerges from my lived experience as a biracial woman in America, serving as a critical lens through which I explore and confront societal shortcomings. This body of work navigates the complexities of race, identity, and cultural memory, particularly focusing on the lasting impacstandards on communities of color especially Black individuals. Layered and multifaceted, my photographs oscillate between sociopolitical critique and intimate portrayals of everyday Black and Brown life, capturing themes of community, love, family, and hair.

Hair, as both subject and symbol, functions as a central motif throughout my work. By documenting commonly used beauty products and …

Forced Sterilizations And Reproductive Control: A Legacy Of Eugenics And White Supremacy In The United States, Bshara Alsheikh

Electronic Theses, Projects, and Dissertations

Women of color have suffered racial reproductive abuse by the hands of government-funded white supremacist institutions. From federal government agencies to the highest court of the land, they have all played a crucial role in the reproductive oppression of women of color and have failed to protect their bodily autonomy. This thesis examines legal cases like Buck v. Bell, Madrigal v. Quilligan, and Relf v. Weinberger to showcase how the bodies and reproductive capacities of women of color have been targeted and controlled under the guise of public health, to advance supposed economic stability, and through a racially charged eugenics …

Precarious Manhood: Masculinity Threats In Gay Men, Andrew S. Rivera

Electronic Theses, Projects, and Dissertations

Manhood is a precarious state that is both sought and easily undermined and demands continual validation from public perceptions. Previous research shows that threats to one's masculinity often coerces reactions of bravado, aggression, and sexual risk-taking behaviors in men in an attempt to reestablish their manhood. However, little empirical attention is paid to deviations of such reactions as a result of varying self-concepts of masculinity and femininity, such as in gay men. In the current study, I explored the different ways in which self-identified masculine and feminine gay men navigate the volatile state of manhood, particularly when confronted with masculinity …

The Effects Of Income On Infant Health: Evidence From The Coal Boom And Bust, Chu Gek Chew

Dissertations and Theses Collection (Open Access)

An individual’s health at birth is an important component in human capital accumulation, posing significant implications both in the short- and long-run. I investigate how infant health outcomes were impacted during a period of successive positive and negative economic shocks led by the coal industry between the 1970s to 1990s. Using exogenous variation within counties’ pre-existing coal reserves, I instrument for the changes in economic opportunities during the coal boom and bust. I find some limited evidence that an increase in income improves infant health outcomes. The incidence of low birthweight is decreasing in earnings growth, and effects are stronger …

Nature Of Smartphone Use: The Underlying Mechanisms Between Nature Exposure And Urge To Use Social Media, Jia Yi Aw

Dissertations and Theses Collection (Open Access)

The urge to use social media is prevalent and costly in modern society. However, little has been researched on how nature exposure can manage urge to use social media to combat its negative consequences. It was hypothesized that nature exposure through Instagram posts in Study 1 and nature park in Study 2 reduces urge to use social media. The underlying mechanisms were tested in a theory-driven serial mediation model, in which positive emotions, attention restoration and self-regulation served as serial mediators. Study 1 employed Instagram experimental manipulation in a laboratory setting by randomly assigning 206 undergraduates to view Instagram accounts …

Essays On Financial Econometrics, Yuexuan Ren

Dissertations and Theses Collection (Open Access)

This dissertation consists of two papers that contribute to the theory of estimation, inference, and prediction using high-frequency financial data. In the first chapter, time-varying betas from return regressions, commonly used to measure systematic financial market risk, are studied using high-frequency data. A novel econometric framework is introduced for the nonparametric estimation of these betas. The optimal finite-sample inference, in a well-defined sense, is enabled by the local Gaussian property of a generic continuous-time benchmark model under the fixed-k framework. Furthermore, a uniform functional inference theory for spot regressions is developed. The proposed methodology is broadly applicable in empirical settings, …

Towards Reliable Ml: Data Attribution And Adversarial Robustness, Xiaosen Zheng

Dissertations and Theses Collection (Open Access)

Modern machine learning (ML) models achieve remarkable success, but face critical reliability challenges. This thesis advances two pillars of reliable ML systems: interpretability through data attribution and robustness against adversarial threats.

In the first part, we develop novel data attribution methods to elucidate the data-model relationship. We establish the critical role of memorization in model generalization through token-level influence analysis, extend sample-level attribution to diffusion models with effective approximation techniques, and introduce REGMIX, a group-level approach that predicts data mixture performance using small-scale experiments. These contributions provide practitioners with scalable tools to audit training data impacts across modalities.

More Than Meets The Eye: Misaligned Expectations In Social Interactions For Individuals With Chronic Illness, Janice Patricia

Dissertations and Theses Collection (Open Access)

Despite the importance of social relationships for well-being, individuals with chronic illness often face barriers that deter them from initiating meaningful connections, such as perceived stigma, fear of rejection, or strained relationships upon a disclosure of their illness. These challenges reveal two key misalignments: overestimated negative (or underestimated positive) expectations of social interactions held by individuals with chronic illness, as well as perceptions held by potential acquaintances. The present study examined how these misalignments hinder social interactions and relationship initiation. Study 1 involved individuals with chronic illness and revealed that participants overestimated the likelihood of awkwardness, disrespect, and rejection, while …

What Makes An Experience Meaningful: A Process/Outcome Approach, Clement Yong Hao Lau

Dissertations and Theses Collection (Open Access)

Scant research has investigated how meaning judgement of an experience are derived; even fewer has examined how these judgements shift over time. To address these gaps, the present research introduced Process/Outcome Meaning Model (POMM)—which proposes that meaning can be derived from two distinct aspects of an experience: its process (i.e., the thoughts, feelings, and behaviors that unfold during the experience) and its outcome (i.e., the results or consequences that follow). POMM further suggests that changes in perceived outcomes may lead to corresponding shifts in meaning judgements over time. Across three studies, participants wrote about and reflected on their personal (positive …

The Influence Of Complex Terrain On The Turin, New York Tornado Of 2023, Alex D. Kramer

Atmospheric and Environmental Sciences Honors Program

Although uncommon as compared to other regions of the United States, the Northeast does experience significant tornados; those rated F/EF3 and above, of which some have had profound impacts on the region. Due to the diverse topography of the region, including its many northsouth oriented river valleys, most of these significant tornados traversed considerable changes in elevation throughout their lifetime. This study seeks to better understand the impacts of local topography on the intensity and overall progression of a significant tornadic event through using the most recent Northeast EF3: the Turin, NY tornado. With the consideration of previous studies involving …

Virtual Reality And Nursing Education: A Randomized Control Trial Of The Effectiveness Of Virtual Reality As A Simulation Modality, David R. Haigh

Dissertations

Virtual Reality (VR) is an emerging technology being utilized in educational and professional training in fields such as engineering, heavy industry, and the military. VR also has the potential to be utilized in pre-licensing nursing education; however, nursing programs have been slow to adopt VR as a simulation modality to train pre-licensed nurses in clinical skills. As such, there is a lack of research on the effectiveness of VR training in critical skills that nurses will utilize in clinical settings. This research is vital because utilizing VR as a training tool can reduce the time and cost of preparing nurses …

Impact Of Shear Flow On Marine Biofilms Using Hyperspectral Imaging, Shantanu Mahesh Kore

All Theses

Various microbial communities in marine biofilms cause biofouling on submerged surfaces, posing challenges to marine industries. Despite their ecological and economic importance, biofilms' biomechanical and biochemical responses to hydrodynamic shear stress are insufficiently understood, particularly in dynamic flow conditions. To fill this gap, our study uses an innovative fiber-optic hyperspectral imaging (HSI) system and a supercontinuum laser source to examine marine biofilms' structure, composition, and detachment behavior at different shear stress levels.

To detect spectral and spatial heterogeneity in live biofilms without labeling, we created a custom imaging pipeline that captures reflectance spectra in the 600-850 nm range, targeting microbial …
