Gender and substance use among Latinx college students: An application of social structure social learning theory.

Social structure social learning theory (SSSL) is a theoretical framework that has been used to understand gender differences in substance use. However, the Latinx community remains understudied in this body of research. Drawing on a Latinx college student sample, we tested the extent to which four social learning mechanisms specified by SSSL theory (positive definitions, neutralizing definitions, differential association, and differential reinforcement) explained gender differences in three substance use outcomes: alcohol intoxication, marijuana use, and illicit prescription drug use.

The Prevalence of Fetal Alcohol Spectrum Disorders in An American Indian Community.

The prevalence of fetal alcohol spectrum disorders (FASD) differs among populations and is largely unknown among minority populations. Prevalence and characterization of FASD is necessary for prevention efforts and allocation of resources for treatment and support. However, prevalence data are lacking, including among many minority populations.

Violence and Disability: Experiences and Perceptions of Victimization Among Deaf People.

Research on the unique experiences of deaf people is rare, and limited information exists regarding the nature and extent of violence against this population. Existing scholarship highlights the increased vulnerabilities of deaf individuals; however, there remains a paucity of research that examines how deaf and hard of hearing individuals perceive their own victimization. Also lacking is research on the experiences of deaf individuals outside of the United States, where cultural norms and the status of the deaf may be quite different.

Cycles of chromosome instability are associated with a fragile site and are increased by defects in DNA replication and checkpoint controls in yeast.

We report here that a normal budding yeast chromosome (ChrVII) can undergo remarkable cycles of chromosome instability. The events associated with cycles of instability caused a distinctive "sectoring" of colonies on selective agar plates. We found that instability initiated at any of several sites on ChrVII, and was sharply increased by the disruption of DNA replication or by defects in checkpoint controls.
