This is a short report of a 'safari' held in conjunction with the International Congress of Nutrition in September 2005, in Futululu, St. Lucia, South Africa. Participants were several members of the International Union of Nutritional Sciences Task Force on Indigenous Peoples' Food Systems and Nutrition, other interested scientists and members of the Kwa Zulu indigenous community. The paper des...

We introduce some new voting rules based on a spatial version of the median in R known as the mediancentre, or Fermat-Weber point. Voting rules based on the mean include many that are familiar: the Borda Count, Kemeny rule, approval voting, etc. (see [35], [36]). These mean rules can be implemented by “voting machines” (interactive simulations of physical mechanisms) that use ideal rubber bands...

We have measured the in-plane scattered distributions of K+ ions incident on a Ag 001 surface with energies from 9 to 100 eV. Energyand angle-resolved spectra of the scattered flux show multiple peaks distinctly separated in energy corresponding to specific ion trajectories at the surface. Using a calculated interaction potential combined with the classical scattering simulation SAFARI we are a...
