In light of rising textbook prices, open education resources (OER) have been shown to decrease non-tuition costs, while simultaneously increasing academic access, student performance, and time-to-graduation rates. Yet very little research to date has explored OER's specific impact on those who are presumed to benefit most from this potential: historically underserved students. This reality has left a significant gap of understanding in the current body of literature, resulting in calls for more empirically-based examinations of OER through a social justice lens. For each of these reasons, this study explored the impact of OER and textbook pricing among racial/ethnic minority students, low-income students, and first-generation college students at a four-year Hispanic Serving Institution (HSI) in Southern California. Drawing upon more than 700 undergraduate surveys, our univariate, bivariate and multivariate results revealed textbook costs to be a substantial barrier for the vast majority of students. However, those barriers were even more significant among historically underserved college students; thus, confirming textbook affordability as a redistributive justice issue, and positing OER as a potential avenue for realizing a more socially just college experience.

Studies of retail environment, one of the social determinants of health, document racial/ethnic disparities in exposure to alcohol and tobacco (A and T) retailers, but have largely overlooked nativity. We examined associations between A and T retailer density and rates of foreign-born Latinx and foreign-born Asian residents in California census tracts (N = 7888), using spatial regressions and controlling for population and ecological confounders (e.g., population density, zoning, residential instability, urbanicity). Socio-demographic data came from the American Community Survey (2012-2016); census tract density of A and T retailers came from geocoded addresses from state license data for off-sale alcohol distributors and purchased data on tobacco retailers from a commercial provider. Models predicting A and T tract retailer density showed that the rate of foreign-born Latinx residents was associated with higher tobacco retailer density but lower alcohol retailer density, and demonstrate no significant associations between rate of foreign-born Asian residents tobacco and alcohol retail density. Retail environment could contribute to observed declines in immigrant health over time in the US and across generations.
