A Longitudinal Examination of Multiple Forms of Stigma on Minority Stress, Belongingness, and Problematic Alcohol Use

College students who experience stigma report problematic alcohol use. However, the stigma-health link focuses on one form of stigma, thereby excluding the intersectional oppression of experiencing multiple forms of stigma. The present work has two primary aims: 1) evaluating whether additive intersectional minority stress confers greater problematic alcohol use among multiply-stigmatized college students one year later, and 2) whether that link can be explained by 1) lower belongingness and 2) greater drinking to cope motives. Students (N=427) ranging in stigmatized identities (14.3% zero; 46.4% one; 29.5% two; 9.8% three or more), participated in an annual health survey at two subsequent fall semesters (2020 to 2021). Structural equation modeling tested the hypothesized model on relations between number of stigmatized identities, minority stressors, belongingness, and coping motive on problematic drinking (risky and problem drinking) one year later. As hypothesized, holding more stigmatized identities predicted higher minority stress, which in turn predicted less belonging. Partially consistent with expectations, lower belonging predicted more problem drinking, but less risky drinking. As expected, higher minority stress predicted higher drinking to cope motives, which in turn, predicted more problem drinking, and risky drinking. In conclusion, belongingness and drinking to cope may be potential mechanisms through which multiply-stigmatized students experience future problem drinking, but that may not always confer to more risky drinking. Implications for universities include implementation of 1) campus-wide belonging interventions for students facing stigma, and 2) initiatives to teach alternative coping strategies that reduce drinking to cope as a strategy to reduce the impact of minority stressors

Mode-Locking in Driven Disordered Systems as a Boundary-Value Problem

We study mode-locking in disordered media as a boundary-value problem. Focusing on the simplest class of mode-locking models which consists of a single driven overdamped degree-of-freedom, we develop an analytical method to obtain the shape of the Arnol'd tongues in the regime of low ac-driving amplitude or high ac-driving frequency. The method is exact for a scalloped pinning potential and easily adapted to other pinning potentials. It is complementary to the analysis based on the well-known Shapiro's argument that holds in the perturbative regime of large driving amplitudes or low driving frequency, where the effect of pinning is weak.Comment: 6 pages, 7 figures, RevTeX, Submitte

COMPORTAMENTO FISIOLÓGICO DE DIFERENTES GRUPOS GENÉTICOS DE OVINOS CRIADOS NO SEMIÁRIDO PARAIBANO

The present study had as objective evaluates the physiologic behavior of different genetic groups of sheep created in the semi-arid paraibano in the dry and rainy times. Forty sheep were used, eight of each genetic group, distributed entirely in a randomized design. There was shift effect, for all the environmental variables and studied physiologic parameters. There were significant interactions of the factors genotypes, time and hour for the parameters, rectal temperature and breathing frequency. With relationship to the Index of tolerance to the heat (ITC) significant effect of the studied factors was not verified. With these results it can be ended that the races Santa Inês, Cariri and the products, resultants of crossings of the animals ½Dorper and ½Damara with sheep without defined race (SRD) they resemble each other in the adaptation aspect to the conditions of the semi-arid
