Epidemic model revisited) In E.xercise 3.7.6, you analyzed the Ker-mack-McKendrick model of an epidemic by reducing it to a certain first-order system. In this problem you ll see how much easier the analysis becomes in the phase plane. As before, let x(t) > 0 denote the size of the healthy population and y(f) > 0 denote the size of the sick population. Then the model is...

Diffusion mechanisms are developed in the more recent economic adoption models other than the epidemic models. The mechanisms of the spread of innovation are either learning effects, i.e. changes in the prior beliefs of potential adopters of the profitability of an innovation, or changes in the stimuli of adoption over time (threshold models) (Thirtle, Ruttan 1987, p. 108). First, different beliefs of firms about the value of an innovation can explain a variance in the date of adoption. Firms then learn about the true profitability of an innovation over time, modify their beliefs and either adopt or reject an innovation (Stoneman 1980). Firms that have a better understanding about the prospect of a profitable innovation would adopt a subsequently successful innovation earlier than other firms.

Numerous applications of GAs within science and other fields have appeared in the literature references to a few of them are given at the end of this chapter. The method has been used for computer learning, modeling of epidemics, the scheduling of the production of fine chemicals, the prediction of the properties of polymers, spectral analysis, and a wide variety of other investigations. In this section we consider a few examples of recent applications in chemistry.

The first scientist to work out the mathematical model of plant epidemics was van der Plank. See Committee on Genetic Vulnerability of Major Crops, Genetic Vulnerability of Major Crops, pp. 28-32. 

Nonadherence has been studied widely by behavioral scientists whose models, such as the Health Belief Model and the Theory of Reasoned Action, attempt to explain and predict nonadherence. However, despite the numerous articles that have been published on this topic, nonadherence remains a problem of epidemic propor-...
