PROEJCT SUMMARY: CORE A The Administrative Core will provide centralized grant administration, data processing and administrative support for the projects. This Core will also serve to amalgamate and unify the investigators, their experimental findings and their ideas, and to track and evaluate research progress and provide organization and leadership directed toward maintaining a highly integrated program. These efforts will occur by 1) providing administrative services to the investigators that include management of project supplies, filing, development of memos, meeting minutes and communications covering all operations, including publications; 2) organizing monthly meetings of program project personnel, quarterly meetings of the Program Steering Committee, annual review meetings that include both the Internal and External Advisory Board members; 3) maintaining integration activities that include data sharing, rapid publication efforts, and identifying and instituting other novel activities critical to maintaining and strengthening program integration; and 4) providing overall fiscal review, accounting, and real time budgets analyses that include reports, verbal communications, reviews and forward-looking projections on expenditures.
