The population structure in most European countries is currently changing, with a shift from younger to older age groups. Only sparse data exist on the impact of these demographic changes on future blood demand and supply. Data on blood recipients are sparse and unconnected to data on blood donors. The first part of this review summarizes studies on the effect of the demographic change on blood...

UNDERSTANDING economic change including everything from the rise of the Western world to the demise of the Soviet Union requires that we cast a net much broader than purely economic change because it is a result of changes (1) in the quantity and quality of human beings; (2) in the stock of human knowledge particularly as applied to the human command over nature; and (3) in the institutional fr...

We investigate conditions under which a model with stochastic demography or population structure converges to the coalescent with a linear change in timescale. We argue that this is a necessary condition for the existence of a meaningful effective population size. We find that such a linear timescale change is obtained when demographic fluctuations and coalescence events occur on different time...

Given that 15-24 year olds have a higher incidence of criminal involvement than other age groups, structural ageing can be expected to have a profound impact on crime trends. The purpose of this paper is to present preliminary findings from a research project that seeks to quantify the proportion of historical and projected change across the Australian criminal justice system attributable to ch...
