Parent involvement (PI) in school is associated with more positive academic performance and social competence in children. However, there are inadequacies in current measures of PI and a need for a better understanding of predictors of PI. In this study, measures were obtained from a normative sample of 387 children in kindergarten and first grade from high-risk neighborhoods in 4 different sit...

Large memories require too much computing resources to be fully extracted and simulated. In this paper we present an accurate power and timing modeling technique that significantly reduces characterization resources. The model is based on current controlled generators, and can be used in several regular structures. Lowpower memories are more easily characterized using this technique, since they...
