We derive here approximate kinetic equations for this model, equations that are based on a $2-$parameter generalization of the statistical-mechanical formalism first proposed by Edwards and coworkers. We show that history-dependent effects, such as memory and Kovacs effects, are captured by this approach.11 pages 6 figures Proceeding Capri 2003 conference "Unifying concepts in granular media and glasses"Statistical Mechanicstext
