Used multiple methods and measures (i.e., youth report, psychiatric interviews, psychophysiological assessment) to investigate the emotional and behavioral impacts of exposure to community violence. Participants were 185 inner-city high school students (M age = 15.4 years; 42% female; 90% African American). Youth with high levels of community violence exposure reported more fears, anxiety, internalizing behavior, and negative life experiences than those with low exposure. No depression or externalizing behavior differences were observed. In a psychophysiological assessment in which adolescents watched a montage of media violence, youth exposed to high levels of community violence had lower baseline heart rates than those with low exposure. There were no between-group differences in physiologic reactivity. Regression analyses revealed that community violence exposure predicted posttraumatic stress and separation anxiety symptoms. The results suggest a significant link between community violence exposure and anxiety symptomatology. Clinical implications are discussed.
The photoconductivity of perylene-bisimide gelators correlates with the perylene radical anion, which is unusually highly stable in air for many hours.
This report describes the first case of naturally acquired inhalation anthrax in the United States since 1976. The patient's clinical course included adjunctive treatment with human anthrax immunoglobulin. Clinical correlation of serologic assays for the lethal factor component of lethal toxin and anti-protective antigen immunoglobulin G are also presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
