The spin structure functions g 1 and g 2 have been calculated in the resonance region and for small and intermediate momentum transfer. The calculation is based on a gauge-invariant and unitary model for one-pion photo-and electroproduction. The predictions of the model agree with the asymmetries and the spin sturcture functions recently measured at SLAC, and the first moments of the calculated...

Jefferson Lab experiment E01-012 measured the 3He spin-structure functions and virtual photon asymmetries in the resonance region in the momentum transfer range 1.0<Q2<4.0 (GeV/c)2. Our data, when compared with existing deep inelastic scattering data, were used to test quark-hadron duality in g1 and A1 for 3He and the neutron. In addition, preliminary results on the 3He spin-structure function ...

Collaborative problem-solving tasks often require learners to co-construct new knowledge by drawing inferences from distributed information. We investigated the impact of information distribution and instructional support on university students’ collaboration in such tasks. Two experiments using specifically designed tasks show a robust negative effect of distributed information on inferences. ...

In experiments published in his book of 1882, Sir John Lubbock demonstrated that removal of the ultraviolet (u.v.) wavelength's decreased the effectiveness of natural sunlight in stimulating ants to carry their pupae into the dark. An apparently high sensitivity to near-ultraviolet light was subsequently shown in studies of phototaxis in bees (Bertholf, 1931a, b; Heintz, 1959) and flies (Bertho...
