It is well documented that the incidence of disease is likely to be affected by distance so that places closer to the source of a disease are most likely to see higher incidence. 2015-01-01 · Abstract. Torsten Hägerstrand's 1953 study of innovation diffusion [1] 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. Using the original aggregated data and Hope-type tests of the ability of the simulations to capture the observed Hagerstrand traces the diffusion process by imitating it with numbers.

Diffusionism assumes that (1) inventiveness is rare and therefore diffusion accounts for nearly all significant culture change and (2) certain places are permanent loci of invention and thus are more advanced and more progressive than other places.

DESIGN OF THE STUDY Although most geographers since the classic Swedish work of Hagerstrand have studied the diffusion of a "single wave" (usually a cultural element such as pasture subsidy or TV ownership), It records the various phaqes in Hagerstrand’s research, from the initial gathering of diffusion data to the identifica- tion of common features in the empirical diffusion patterns, the con- struction of an initial diffusion model, and the successive modifica- tions of this model so that it could produce patterns close to the ones Torsten Hägerstrand's 1953 study of innovation diffusion [1] was pathbreaking in many ways. It was based on an explicit micro-model of information spread, and on Monte Carlo simulation of the diffusion processes from among other processes producing similar observable outcomes.

Using the original aggregated data and Hope-type tests of the ability of the simulations to capture the observed Hagerstrand traces the diffusion process by imitating it with numbers. Such imitation, leading to prediction or forecasting of the pattern of diffusion, is called a simulation of diffusion.

condensing stage. number of new cases equal in all areas. 6 of 7 After looking at reality, Dr. Sarre then attempts to simulate the spread of the disease with a Hagerstrand diffusion model. Comparing the reality with the results of the simulation, Dr. Sarre tentatively concludes that the elm bark beetle, the carrier of the disease, has too short a flight pattern to account for the spread of the disease so rapidly over such long distances.
