The dimensions of the Westheimer function are stable across populations and in time and vary with the eccentricity of fixation. The function is thus useful to assess whether an individual is fixing centrally and if not to estimate the degree of eccentricity of fixation. We identified both summation and inhibition-like regions in a 66-year-old woman with senile macular degeneration and estimated...

The DEISA Mini-Symposium held in conjunction with the ParCo 2009 Conference was devoted to ŞExtreme Computing in an Advanced Supercomputing EnvironmentŤ. For a representative overview of the application related key areas involved, the Mini-Symposium was structured into three sessions devoted to the description of the DEISA Extreme Computing Initiative DECI and the Science Community support, the...

Slovenia is embarking on an ambitious health sector reform program, a small part of which involves implementing the categorization of acute inpatients by DRG for payment purposes. I summarise the leading DRG variants, and describe the process of selecting one of them. I argue that the Slovenian decision to use the Australian DRG variant as a starting point was sensible in terms of cost, speed o...

There were and largely continue to be no descriptions of hospital outputs other than the number of inpatients and their average length of stay. Before 1995, the product of both figures determined the daily fee of a hospital. For example, a hospital with 20,000 inpatients having an average LOS of 7 days would be funded for 140,000 patient days. Assuming a total budget of DM70 million, the daily ...

One matter on which we were agreed is that, with respect to areas of potential improvement in Australian DRGs, Hindle (2001) agrees with us! Most of the ideas that he presents have been the subject of informal discussions among interested parties across the Tasman. Hindle does not claim otherwise, but adds to our understanding by presenting the ideas in a clear and relatively comprehensive way....
