A Geographic Framework for the Optimal Placement of Interventions for Opioid Treatment Deployment in Underserved Areas (OPIOID-UA)
The scale and cadence of crises affecting large populations is on the rise. These crises or gradual onset disasters can be considered shocks or disruptions to social systems. The impacts of many of these shocks do not affect populations equally, but differentially based on social class, race, …
