Hager-strand’s Model: Hagerstrand, a Swedish geographer, was a professor of Geography at Lund University, where he received his doctorate in 1953. 2015-01-01 · Torsten Hägerstrand's 1953 study of innovation diffusion was pathbreaking in many ways. It was based on an explicit micro-model of information spread, and on Monte Carlo simulation of the hypothesised spatial process. Innovation Diffusion As a Spatial Process Hardcover – June 1, 1967 by Torsten Hagerstrand (Author), Torsten Hägerstrand (Author), Allan Pred (Editor), Greta Haag (Translator) & 1 more Reflecting a further shift in disciplinary focus, Derek Gregory provides a highly nuanced essay that begins with components of Hagerstrand’s diffusion model, rephrases the usual interpretation, and uses it as a launch pad to advocate a broader and deeper understanding of social processes, including the role of inequality, class, and the social milieu within which adoption/diffusion occurs. By diffusion in geography, we are usually talking about “contagious diffusion”, or the widespread dispersal of an innovation, culture, disease, etc, from a centre or centres.

Malaria is one of the most important parasitic infections in humans and more than two billion people are at risk every year. To understand how the spatial heterogeneity and extrinsic incubation period (EIP) of the parasite within the mosquito affect the dynamics of malaria epidemiology, we propose a nonlocal and time-delayed reaction–diffusion model.

Hagerstrand Saturation stage. Malaria is one of the most important parasitic infections in humans and more than two billion people are at risk every year. To understand how the spatial heterogeneity and extrinsic incubation period (EIP) of the parasite within the mosquito affect the dynamics of malaria epidemiology, we propose a nonlocal and time-delayed reaction-diffusion model. Hagerstrand suggests that spatial-diffusion processes are governed by the flow of inter-personal information.
