  abstract =	 {Today, public-service delivery mechanisms such as
                  hospitals, police, and fire departments rely on
                  digital generation, storage, and analysis of vital
                  information. To protect critical digital resources,
                  these organizations employ access-control
                  mechanisms, which define rules under which
                  authorized users can access the resources they need
                  to perform organizational tasks. Natural or man-made
                  disasters pose a unique challenge, whereby
                  previously defined constraints can potentially
                  debilitate an organization's ability to act. Here,
                  the authors propose employing contextual parameters
                  — specifically, activity context in the form of
                  emergency warnings — to adapt access-control
                  policies according to a priori configuration.},
