Recent experimental and theoretical results on kaon semileptonic decays have significantly improved the determination of the CKMmatrix element Vus. After briefly summarizing the impact of the new experimental determinations, I will concentrate in this talk on the theoretical progresses, coming in particular from lattice QCD calculations. These results lead to the estimate |Vus| = 0.2250± 0.0021...

The purpose of the Self-determination Theory is to explain motivation and behaviour based on individual differences in motivational orientations, contextual influences, and interpersonal perceptions. The theory has shown utility in explaining the antecedents and processes that underpin exercise behaviour. This review will provide an overview of the theory and its application in explaining healt...

We formulate a number of open problems for time-harmonic inverse electromagnetic scattering theory focusing on uniqueness theorems, the determination of the support of a scattering object and the determination of material parameters

Studies in 2 work organizations tested a self-determination theory based model in which employees’ autonomous causality orientation and their perceptions of their managers’ autonomy support independently predicted satisfaction of the employees’ intrinsic needs for competence, autonomy, and relatedness, which in turn predicted their performance evaluations and psychological adjustment. Path anal...
