Children's mental representations of situations involving another child's distress were examined in two studies. Study 1 examined 3- to 7-year-old children's (n = 44) ideas about what victims and bystanders would think, feel and do in hypothetical situations. In Study 2, 7- to 8-year-olds (n = 40) described their own cognitive response to situations in which they were confronted with another's dis

Exercise during growth and adolescence increases bone mineral density (BMD) in weight-loaded skeletal regions. The development of BMD in unloaded or minimally loaded regions during activity is unclear. We measured BMD in one unloaded, one partly loaded and one highly loaded skeletal region in 67 active soccer players, mean age 22.7 years (range 17-35 years), 128 former soccer players, mean age 54.

We discuss the tunneling between two parallel modulated two-dimensional electron systems in tilted magnetic fields. The electronic states are described in terms of the magnetic crystal momentum, and tunneling events connect the states whose momenta differ by a shift due to the in-plane component of the field. We use this fact to develop a theory of how the features of the artificial two-dimensiona

The generalized hole corrected Debye-Huckel theory (Penfold et al J. Stat. Mech. (2005) P06009) is implemented. Predictions of thermodynamic functions and simple structural properties compare favourably with results from closure of the Ornstein-Zernike integral equation in the mean spherical approximation, and with Monte Carlo simulation of the charged hard sphere primitive model. A strictly nonel

The sex- and age-specific incidence has been calculated for ankle fractures from the first part of the 1950s and compared with the 1980s, a 30-year interval. The fractures were also classified according to Lauge-Hansen. Altogether 1784 fractures were found. During that time interval ankle fractures had become more common, particularly those with extensive skeletal involvement, such as the stage IV

Controversy surrounds the impact of atmospheric nitrogen (N) deposition on frost hardiness. There are no specific field studies and the relevance of data from N fertilizer studies is questionable. Field N manipulation experiments with Norway spruce [Picea abies . (L) Karst.] at Skogaby, Sweden, and Sitka spruce [P. sitchensis . (Bong.) Carr.] at Aber in Wales and Deepsyke in Scotland were sampled

OBJECTIVE. To evaluate the recurrence of foot ulcers as well as the cumulative amputation and mortality rates in diabetic patients with previous foot ulcers. DESIGN. A prospective study of consecutively presenting diabetic patients admitted to the Department of Internal Medicine because of foot ulcer with a median follow-up of 4 years. SETTING. A multidisciplinary foot-care team. POPULATION. Five-

This study was undertaken in order to compare regional cerebral blood now (rCBF) and EEG findings of patients with clinically diagnosed dementia with Lewy bodies (clinDLB) and Alzheimer’s disease (clinAD). Furthermore, within the clinDLB group to compare cases with and without neuropathologically verified Lewy bodies (LBs). When we studied 200 dementia cases in a prospective longitudinal dementia

We present a formulation of the scattering matrix method for spin-dependent electron transport in a quantum waveguide with spin-orbit interaction (SOI). All the required Hamiltonian matrices needed in the implementation of the formulation are represented in a basis of the transverse spatial eigenstates and the spin eigenstates of the leads. Thus the method has great flexibility and can be easily a
