School Leaders’ Perceptions Of Restorative Practices On Student Behavior, Jennifer Mary Herold Fontenot

Electronic Theses and Dissertations

United States public schools turned to a zero-tolerance approach to school discipline with hopes of improving school safety and climate in the 1990s. Administrators dispensed consequences such as suspension and expulsion without considering the whole student, regardless of the student’s conditions, motivations, or background. Many schools today focus on punitive measures rather than a holistic approach that considers the root causes of behavior, such as socioeconomic factors, mental health issues, or the student’s home life. Such actions can lead to disproportionately harsh punishments for marginalized students, particularly those from low-income backgrounds or communities of color, exacerbating existing inequalities. Thus, the …

Comparing Ordinary Least Squares And Quantile Regression: A Causal-Comparative Approach To Modeling Conditional Relationships, Samuel Nnorom

Electronic Theses and Dissertations

Ordinary Least Squares (OLS) regression has traditionally been the preferred quantitative method for estimating linear relationships. However, it assumes that the effect of a predictor variable remains constant across the entire outcome distribution, which can miss important insights when data are heterogeneous. Quantile Regression (QR), on the other hand, offers a more detailed analysis by focusing on the full response variable distribution, thereby revealing different relationship patterns at various quantiles within the outcome. This study compares how OLS and QR perform in modeling conditional relationships within a causal-comparative framework based on ex post facto research. Using the mortality data from …

Influence Of Obesity On Knee Joint Mechanics: A Subject-Specific Musculoskeletal Modeling Approach, Ryan C. Knowles

Electronic Theses and Dissertations

Obesity has been consistently linked to knee osteoarthritis (KOA), a debilitating joint disease. While prior work has shown that obese individuals often walk with altered biomechanics compared to normal-weight (NW) individuals, which may accelerate KOA progression, less is known about how these mechanics affect load distribution between the medial and lateral tibiofemoral (TF) compartments, particularly during higher-demand activities. This study developed subject-specific musculoskeletal models of five obese and five NW individuals, incorporating CT-based bone measurements and individualized joint contact points. Simulations were driven by six degree-of-freedom (6DOF) kinematics obtained from high-speed stereo radiography (HSSR) to predict TF loading and associated …

The Multicultural Orientation Framework In Couple Therapy, Jasmine R. Davis

Electronic Theses and Dissertations

Couples’ cultural values and beliefs are important to their relational connection. Cultural values and beliefs can be sources of strength in relationships, but they can also lead to impasses. As such, clinicians and researchers could benefit from a cultural framework to inform conceptualization and treatment when working with couples. The Multicultural Orientation (MCO) framework has three pillars: cultural humility, cultural comfort, and cultural opportunities. The MCO framework is empirically supported for use in individual and group psychotherapy but has not been applied to couple therapy. This dissertation includes two parts. First, we outline a conceptual framework for the application of …

A Phenomenological Study Of Caregivers For Sexual Minority Hospice Patients, Catherine H. Bianchi

Electronic Theses and Dissertations

Lesbian, gay, and bisexual (LGB) individuals face disproportionate barriers in healthcare across the lifespan that persist and often intensify at the end of life. Despite hospice’s mission to provide comfort, dignity, and patient-centered support, it remains unclear whether these services equitably meet the needs of sexual minority patients. Seeking hospice care presents a unique conundrum for many LGB individuals: it necessitates inviting representatives of a historically exclusionary healthcare system into the privacy of their homes - spaces that often serve as sanctuaries of identity, safety, and autonomy. The already vulnerable experience of seeking care in one’s final days can be …
