Using interview and observation data from white and African-American parents of murdered children, this article explores a primary social process accompanying acute loss: the social construction of blame. Findings reveal that race and class are primary forces that shape not only the experience of loss, but also attributions of cause, designations of blame, and the construction of post-mortem identities. While poor Black informants encountered avoidance strategies on the part of authorities (e.g., police) when their child was murdered, whites and upper middle-class Blacks received emotional support. This differential treatment by authorities led to either legitimate or disenfranchised grief, both of which were addressed by the strategy of “sanctification,” a form of emotion work.
The efficacy of powered air-purifying respirators, surgical masks, dust/mist respirators, and high-efficiency respirators were tested with a biological aerosol under simulated breathing conditions. Protective ability ranged from 67 to 99.95%. The majority of penetration in negative-pressure respirators occurred at the face-mask interface rather than through the filter material.
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.
