Lifelong competence development is a fundamental premise for an information society, as well as major aim and challenge. Facing the variety of learning programs and qualification measures, problems emerge in supporting lifelong learning. Efficient competence development necessitates providing learners with learning opportunities which are appropriate for their current knowledge and for their in...

The quadruple system PG 1115+080 is the second gravitational lens with a reported measurement of the Hubble constant. In addition to the primary lens, three nearby galaxies are believed to contribute significantly to the lensing potential. In this letter we report accurate redshifts for all four galaxies and show that they belong to a single group at zd = 0.311. This group has very similar prop...

We employ Schwarzschild’s method of orbit modeling to constrain the mass profiles of the central lens galaxies in 0957+561 and PG 1115+080. We combine the measured central projected stellar velocity dispersions of these galaxies with the self-similar radial profiles of the rms velocity and of the Gauss-Hermite moment h4 observed in nearby galaxies for 0 <∼ R <∼ 2Reff . For 0957+561, we find a 1...

Quality assurance (QA) and continuing competence (CC) programs aim to ensure acceptable levels of health care provider competence, but it is unknown which program methods most successfully achieve this goal. The objectives of the study reported in this article were to compare two distinct QA/CC programs of Canadian dental hygienists and assess the impact of these two programs on practice behavi...
