The end-of-semester crush is here, and campus is bustling with activities from presentations and projects to finals. Among the many senior capstones presented in recent days was one by Gaven D. Crosby, of Benton. Crosby and seven other seniors in Penn College's emergency management technology major were charged with applying classroom concepts and best practices to develop a program or research paper that solves an issue or problem in the field. Crosby interned with the Army National Guard Homeland Response Force and collected data to determine the adaptability of the Department of Defense’s chemical, biological, radiological and nuclear response to non-CBRN disasters. Of course, the grand finale of the semester will be Fall Commencement, set for Saturday, Dec. 16.
