Spatial Segregation in Demography: A Short Review
Abstract. Spatial has always been an inherent component of demography, and demographic processes are inherently spatiotemporal. Recognizing the importance of spatial in general and spatial segregation in particular in demographic analysis has created new positions in demography and its conceptual and analytical frameworks. The notion of spatial segregation refers to the distribution of social...
متن کاملInformation flow among fishing vessels modelled using a Bayesian network
Reaction of fishers is an essential source of uncertainty in implementing fishery management decisions. Provided they realistically capture fisher behaviour, models of fishing vessel dynamics provide the basis for evaluating the impact of proposed management strategies. Information flow among vessels has not been a major focus of such models however, although it might play a critical role in ho...
متن کاملSegregation in diffusion - limited multispecies pair annihilation
The kinetics of the q species pair annihilation reaction (A i + A j → ∅ for 1 ≤ i < j ≤ q) in d dimensions is studied by means of analytical considerations and Monte Carlo simulations. In the long-time regime the total particle density decays as ρ(t) ∼ t −α. For d = 1 the system segregates into single species domains, yielding a different value of α for each q; for a simplified version of the m...

متن کاملThe Use of Gis to Analyse the Spatial Distribution of Fishing Effort in Coastal Fishery
Based on two models focussing on the analysis of the spatial components of the fishing effort distribution, we present a global approach which has been formalised in order to develop a computerized simulation tool called FAST (Fishing Activity Simulation Tool), distributed as an extension of ESRI ArcView GIS Software. FAST defines a logical framework under which the knowledge about fishing effo...
