Professor Emeritus Ralph Taylor, Brian Lockwood, and Brian Wyant's article on Philadelphia streetblock 311 calls and physical incivilities appeared online in the Journal of Crime & Justice in January, 2023. The article asks "Can streetblock 311 physical incivility call count shifts predict later changing on-site conditions?" Many urban informatics scholars suggest 311 call patterns can serve as acceptable proxy indicators of changing on-site conditions. The article considers whether that assumption is warranted. The article provides a model analysis for gauging ecological construct validity, a key challenge in community criminology.
