Empirical Bayes estimators for the cross-product ratio of 2x2 contingency tables
… of sampling distributions of cell counts of 2x2 contingency tables were considered. In the Independent Poisson Case, an empirical Bayes estimator for the cross-product ratio is presented. If the squared error loss function is used, this empirical Bayes estimator, ᾶ, has asymptotic risk only ε …

Can goal specific self-efficacy measures predict goal choice: understanding the 2x2 achievement goal framework through self-efficacy theory
<p>The achievement goals that one adopts in an academic context have been shown to be associated with, as well as causally related to, important outcomes. Currently, the most widely accepted theory holds that achievement goals are the result of one's implicit </p> <p>theory of intelligence. …

Investigation of hydrogen chemisorption on the tungsten (100) surface
… in the literature. The intensity of the c(2x2) pattern associated with the S2 hydrogen state maximizes at a work function change with adsorption of 0.15 eV. LEED elastic intensity profiles have been obtained for several low index beams. These are compared to theoretical, microscopic model …
