diffusion and control to identify profit-maximizing strategies for GLRD diffusion control. The model allows for a full spatial-dynamic characterization of the disease diffusion. It relaxes the assumptions of homogeneity and perfect mixing. Instead, in the model, the choice of disease control strategy takes into account agent heterogeneity in With no information on diffusion seasonality, we do not model seasons and assume for simplicity that disease diffusion and control can take place in any month. 13 Experimental Design We design and implement Monte Carlo experiments to evaluate nonspatial and spatial disease control strategies by comparing their bioeconomic outcomes to those resulting from a strategy of no disease control.

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. If, however, inventiveness and innovativeness are IOAIO IUSIO : COEMOAY GEOGAICA AOACES ISS 006642 IS 0 8604 68 C G. Clr, 84 blhd b G , rh rntd b .. thn & Sn, rh G.

However, the diffusion of saffron farming did not follow the exact What are the global patterns of disease and can factors be identified that determine these?

Acute symptoms of the disease include high fever, chills, headache, and fatigue, with common complications such as coma, anemia, and liver damage. What are the global patterns of disease and can factors be identified that determine these? Key Idea 1a:Diseases can be classified and their patterns mapped. The spread of disease is complex and influenced by a number of factors. Learning Objectives: To analyse how disease spreads (diffusion). spatial diffusion research to the developed countries, to the neglect of the developing countries. A gap therefore exists in the literature concerning the developing countries.
