Lifting aims at improving the efficiency of probabilistic inference by exploiting symmetries in the model. Various methods for lifted probabilistic inference have been proposed, but our understanding of these methods and the relationships between them is still limited, compared to their propositional counterparts. The only existing theoretical characterization of lifting is a completeness resul...

It is well-known that the estimated GARCH dynamics exhibit common patterns. Starting from this fact we extend the Dynamic Conditional Correlation (DCC) model by allowing for a clustering structure of the univariate GARCH parameters. The model can be estimated in two steps, the first devoted to the clustering structure, and the second focusing on correlation parameters. Differently from the trad...

Fluoride was measured in the spontaneous urine of a group of persons (n = 397) occupationally non-exposed to fluoride. At a concentration less than 2 . 10(-4) g/kg fluoride in drinking water the mean fluoride excretion in urine is 0.61 mg/l F with an upper limit of 2.00 mg/l F. The 95-percentile of normal fluoride excretion is 1.0 mg/l F. By correcting the values for the specific gravity of 1.0...

Recent evidence from economics and psychology highlights the importance of traits other than general intelligence for success in school and in life (Almlund, Duckworth, Heckman, & Kautz, 2011; Borghans, Duckworth, Heckman, & ter Weel, 2008; Moffitt et al., 2011). Disparities in so-called non-cognitive skills appear to contribute to the academic achievement gap separating wealthy from disadvanta...
