What does the free space Lambda Lambda interaction predict for Lambda Lambda hypernuclei?

Data on LambdaLambda hypernuclei provide a unique method to learn details about the strangeness S = -2 sector of the baryon-baryon interaction. From the free space Bonn-Jülich potentials, determined from data on baryon-baryon scattering in the S = 0,-1 channels, we construct an interaction in the S = -2 sector to describe the experimentally known LambdaLambda hypernuclei. After including short-range (Jastrow) and RPA correlations, we find masses for these LambdaLambda hypernuclei in a reasonable agreement with data, taking into account theoretical and experimental uncertainties. Thus, we provide a natural extension, at low energies, of the Bonn-Jülich one-boson exchange potentials to the S = -2 channel.

A validity study of the social skills rating system-teacher version with disabled and nondisabled preschool children.

This study examined the differences among social skills and problem behaviors of disabled (n = 22) and nondisabled (n = 27) preschoolers on Social Skills Rating System-Teacher Version. Significant differences were found between the two groups on all measures of social skills and all but one measure (internalizing problems) of problem behaviors. Also, correlations with a measure of social competence and 8 teachers' ratings strongly supported the validity of this measure of social skills for preschool children. Implications for designing early intervention programs are discussed.
