Some of these success stories represent many years of work; some are about programs just underway that hold the promise of future benefits. The simple format of stating an issue, the action taken to address the issue, and the impact or benefits of the work provides easy-to-read success stories. These impact statements and those from recent years are on the Arkansas Agri- cultural Experiment Station Web site at: http://arkansasagnews.uark.edu/394.htm Faculty Impact Statements 2009 Contents Competitive Agricultural Systems in a Global Economy—Animal Systems Variation in quality characteristics of fresh pork bellies / J.K.
