The purpose of this research was to investigate the effectiveness of instruction of metacognitive knowledge on academic stress in high school female students. This research method is quasi experimental with pretest and post test. Given this, 37female first grade students (19 subjects in experimental group and 18 subjects in control group) were randomly selected using multi-stage cluster samplin...

The surface affinity of the hydronium ion in water is investigated with umbrella sampling and classical molecular dynamics simulations, in which the system is described with the effective fragment potential (EFP). The solvated hydronium ion is also explored using second order perturbation theory for the hydronium ion and the empirical TIP5P potential for the waters. Umbrella sampling is used to...

Prediction of random effects is an important problem with expanding applications. In the simplest context, the problem corresponds to prediction of the latent value (the mean) of a realized cluster selected via two-stage sampling. Recently, Stanek and Singer (JASA, 2004) developed best linear unbiased predictors (BLUP) under a finite population mixed model that outperform BLUPs from mixed model...
