This paper expands the diffusion of information models developed by Funkhouser and McCombs (1972) to include situations involving simple interaction processes and more complicated situations involving both mass mediated messages and interactively mediated messages. This paper develops discrete time models of information diffusion as opposed to the continuous time models developed by Coleman (1964) and Bartholomew (1967) and others. [ABSTRACT FROM AUTHOR]

Mayhew's baseline model predicting the relative size of the elite in a social system comprised of two stratified sub-classes is extended to the area of social power. Two basic measures of social power, a compliance ratio, and a coefficient of asymmetry (a measure of differentiation) are discussed. It is noted that the average compliance ratio for the elites is essentially a constant, while the average compliance ratio for non-elites is decreasing monotonic function of system size. The coefficient of asymmetry is an increasing monotonic function of system size. Social-psychological bases for system growth are suggested. [ABSTRACT FROM AUTHOR]
