"Patient allocations according to circumstances and preferences: Modelling based on the Norwegian patient list system".
Abstract:
In some countries every citizen has the right to obtain a designated general practioner. However, each individual may have preferences that cannot be fulfilled due to shortages of some kind. The questions raised in this work are: To what extent can we expect that preferences are fulfilled when the patients "compete" for entry on the lists of practioners? What changes can we expect under changing conditions? A particular issue explored in the is when the majority of women prefer a female doctor and there is a shortage of female doctors. The analysis is done on the macro lever by the so called gravity model and on the micro level by recent theories of benefit efficient population behaviour. The approach is quite general and can be applied in a variety of contexts.
Møtet er åpent for alle medlemmer og andre interesserte! Vi oppfordrer også studenter til å komme. Årsmøte for 2006 avholdes etter foredraget, etterfult av sosialt samvær med enkel servering!

"Comparing and combining effort and catch estimates from aerial-access designs, with applications to a large-scale angler survey in the Delaware River"
We used an access point survey in conjunction with an aerial effort survey to estimate effort, catch and harvest of American shad and striped bass by recreational angler in the Delaware River and upper estuary from March through October in 2002. A probablistic design was used to schedule sampling of anglers across 82 access points and flights over the river weekly throughout the study period. Time intervals within the core aerial survey days were selected with probabilities proportional to the observed distribution of daily effort in a prior aerial-access survey. During the peak shad run we scheduled additional, independent, weekly flights during the time of day with expected maximum effort. Results suggest that counts near or at peak angler effort can produce more precise effort estimates than randomly scheduled counts. However, the non-random schedule resulted in biased effort estimates unless current estimates of daily effort distribution from the access survey were used for extrapolating instantaneous counts from each flight. We also estimates effort directly from the probability-based access survey. The aerial and access surveys produced similar estimates of effort for boat anglers; we used a composite estimator, with a higher weight assigned to the more precise survey estimate, to combine these estimates. For shore anglers, the access survey procued significantly higher estimates of effort than the aerial survey, especially in the tidal portion of the river, most likely due to flight restrictions enfored after September 11, 2001. The ues of a composite estimate of effort for boat anglers, and an access-based effort for shore anglers improved the precision of the total catch estimates. We achived the target of 20% in relative standard error (RSE) for estimated recreational catch of American shad (29,662; RSE=18%) and striped bass (51,106: RSE=15%).

Volstad skal jobbe ved Havforskningsinstituttet f.o.m. høsten 2007. Han skal lede et HI prosjekt for å kartlegge turistfisket i Norge, i samarbeid med statistisk sentralbyrå, og han ønsker å komme i kontakt med statistikkstudenter. Studenter, medlemmer og andre interesserte oppfordres herved til å stille opp! Møtet avsluttes med sosialt samvær og enkel servering!
