1. There are also analogies between finance theory and diffusion theory . 2. Examples are found in biology, geology and physics ( neutron diffusion theory ) and ecology. 3. Proponents of diffusion theory recognised the limitations of mass media, however, in promoting sustained behavioral change. 4. The bibliography Menzies showed me is often used to support something called " diffusion theory ." 5. Diffusion theories can never account for all variables, and therefore might miss critical predictors of adoption.6. Using these data, he quantified radical loss from particles, showing that simple diffusion theory could explain the results. 7. For instance, in diffusion theory , the form of something moves from one culture to another, but not its meaning. 8. The form of the expression for shrinkage halftime \ tau _ { sh } is based on the diffusion theory . 9. A Monte Carlo approach can be used to make up for the Diffusion Theory 's inherently poor accuracy near the boundaries. 10. A variant of the diffusion theory , stimulus diffusion, refers to an element of one culture leading to an invention in another.
