That is, all studies are viewed as estimating a common, or fixed, population effect size.
In his 1957 science fiction novel The Naked Sun Isaac Asimov invented a world, Solaria, in which a tiny, fixed population of humans live out their days on enormous estates, waited upon by scores of robots.
In the implementation of the long-run closure of the model, aggregate employment is determined by fixed population change, fixed labor force participation rates, and the "natural" unemployment rate (the unemployment rate at the start of the simulation).
We consider a fixed population, C, of uninfected cells exposed to a pool of V virions.
3) WT+SN communities grow at a more or less constant but relatively low speed, and have a fixed population composition.
We assume fixed population size of N, which means we have N alleles in all.
For simplicity, we will consider a fixed population of mtDNAs of size N, though this reasoning extends to changing population size.
Perhaps the most stringent assumptions made by our model concern the metapopulation dynamics: the model is non-spatial, has fixed population sizes, and has a simple model of extinction and recolonization.
17 Surviving surgeon superintendents' logbooks from long voyages provide a unique historical record of medical events, effectively providing data on outbreaks in a closed cohort with a known number of susceptibles and a fixed population.
The study population included subjects who were resident in Tayside and registered with a GP in January 1994 and remained in Tayside until December 2003 or died during the study period—a fixed population (n = 347 1347.
Previous analyses of rapid evolution of cooperation that assume fixed population sizes often focused on identifying whether rapid evolution enhances or suppresses the evolution of cooperation, while potential density dependent-effects are usually ignored [ 15- 18].
