Project Summary – Core A The Administrative Core (Core A) guides and supervises the overall Program Project research effort. The Director has ultimate responsibility for supervision of Program Project activities. The Director is assisted by the Co-Director. An important function of the Core is to organize and schedule bi-monthly meetings of all Program Project personnel and maintain written records of these meetings. Frequent meetings documented with reports presented by Project and Core Leaders ensure that all projects are meeting Program goals. Project and Core Leaders meet separately at least once a month to discuss progress, trouble-shoot scientific or technical issues and make policy decisions. Electronic records of all group meetings are available to Program personnel through a Program Project Electronic Group (Teams). Microsoft Teams allows for easy, group specific communication of text, images, documents, etc. Core A communicates with the Internal and External Advisory Committees. These committees monitor Program Project research progress and provide evaluations and critiques of the group effort. They also assist the Director in developing solutions to any research-related problems that may arise, and they give the Director leverage to help hold the overall Program Project accountable for the proposed work. Core A is responsible for monitoring Program expenditures, including travel by Project Leaders, and routine bookkeeping. Publication costs arising from Program Project-funded research will be processed through individual projects. Finally, Core A handles assembly and submission of annual progress reports with continual encouragement for investigators to be active at scientific meetings that helps promote and integrate their findings into scientific knowledge. Core A is overall responsible for the service to, training of and development of PPG personnel.
