... neighborhoods of low collective efficacy with hot spots and neighborhoods of high collective efficacy with cold spots, the map also revealed a different kind of risk: neighborhoods with high collective efficacy that are in close proximity to high-risk areas have very high homicide rates themselves. Conversely, "spatially advantaged" neighborhoods (which border low-risk areas)
