A latent profile analysis of psychological sense of community and ethnic identity among racial-ethnic minority young adults from the southwestern United States.

Among young adults fof color, both sense of community and ethnic identity, as developmental processes, have been associated with wellness, empowerment, and civic action. Additional research is needed that provides empirical support for the connection between psychological sense of community and ethnic identity on outcomes that relate to human development such as intrapersonal psychological empowerment, civic engagement, and depression symptoms. The current study of young adults of color (N = 243; 70% Hispanic/Chicano(a)/Spanish and 10% American Indian/Native American; 70% female) investigates heterogeneity according to dimensions of psychological sense of community and the ethnic identity construct.

A Spatial Analysis of Alcohol Outlet Density Type, Abandoned Properties, and Police Calls on Aggravated Assault Rates in a Northeastern U.S. City.

Community-based research and prevention scholarship has shown a growing interest in examining the impact of the ecological structure of neighborhoods on community violence. Ecological structures such as higher numbers of alcohol outlets and abandoned/vacant properties in geographically dense, poor, and socially isolated communities are critically important to consider. Further, disadvantaged urban communities are burdened by greater police presence with limited or no abatement in crime or violence.

Does caffeine counteract alcohol-induced impairment? The ironic effects of expectancy.

Objective: Studies have shown that expectations of alcohol-induced impairment can produce adaptive responses to alcohol that reduce the degree of behavioral impairment displayed. The present study tested psychomotor performance following combined caffeine and alcohol administration in 42 social drinkers (23 men). Subjects were led to expect either that caffeine would antagonize alcohol-induced impairment or that it would have no effect.

Sex and rat strain determine sensitivity to kappa opioid-induced antinociception.

Rationale: Recent studies indicate that sex and rodent strain are determinants of sensitivity to opioid-induced antinociception.

Objectives: The present study examined the influence of sex and rat strain on kappa opioid-induced antinociception using a series of kappa opioids that vary in their relative effectiveness.

Methods: In a warm-water (50, 52 and 55C) tail-withdrawal procedure, the antinociceptive effects of kappa opioids were determined in male and female rats of the F344, Lewis and Sprague-Dawley (SD) strains.
