Weathering The Divide: Social Determinants, Neighborhood Context, And Systemic Lupus Erythematosus Among African American Women, Vanessa Cl Morman

Electronic Theses and Dissertations

Background: Systemic lupus erythematosus (SLE) disproportionately affects African American women and contributes to racial health disparities in the United States. Although genetic susceptibility influences disease risk, growing evidence suggests that social determinants of health (SDOH), including neighborhood conditions, structural racism, and socioeconomic disadvantage, contribute to disease development and progression. Epigenetic mechanisms may provide a biological pathway linking adverse social conditions to chronic disease disparities. This dissertation examined the influence of SDOH on SLE disparities through evidence synthesis and empirical investigation to inform public health practice and policy.

Methods: This integrated learning experience consisted of three complementary manuscripts. Aim 1 was …

Breaking The Cycle: From Victimization To Offending Through The Lens Of Human Services, Colette R. Penalosa

Master of Arts in Human Services

The victim-offender overlap challenges the common view that victims and offenders are separately labeled by recognizing that both groups have experienced significant childhood trauma, physical, emotional, and psychological abuse, neglect, and other adverse childhood experiences (ACEs). Current research implies these experiences can increase the risk of offending as they all influence cognitive and behavioral development while leaving criminal behavior undetermined. The purpose of this capstone is to analyze the relationship between childhood victimization and offending from a human service perspective; analyzing the pathways a victim takes on the road to offending. Research conducted will focus on exploring the victim-offender overlap, …

Bridging Fiscal Sustainability And Health Equity: A Policy Analysis Of California’S Healthcare Coverage Safeguards, Guadalupe Castaneda Martinez

Master's Projects and Capstones

Without structural policy intervention, approximately 4.6 million Californians remain at risk of being uninsured by 2030, worsening racial and ethnic health disparities and hospital uncompensated care burdens. This policy analysis advocates for a hybrid universal coverage model combining sliding-scale subsidies (California Senate Bill 78) with full-scope Medi-Cal expansion for all income-eligible residents regardless of legal status (California Assembly Bill 133). The framework relies on existing funding mechanisms, including the Managed Care Organization tax and the Health Care Affordability Reserve Fund. Comparative analysis indicates that market-only subsidies leave severe equity gaps, whereas immediate single-payer transitions pose substantial fiscal and administrative risks. …
