The presence of a major repulsive ion-induced structural force or disjoining pressure between Ca-clay particles is demonstrated. This arises from the perturbation of the normal structure for water to distances of about 50 A. This force operates in slit-shaped pores between clay particles and is opposed principally by attractive ion-ion correlation forces in regions of clay particle overlap.

Listening, a significant dimension of the behavior of hearing-impaired children, may be measured directly by recording childrens' responses to obtain audio narrations programmed via a conjugate reinforcement system. Twelve hearing-impaired, school-aged children responded in varying ways to the opportunity to listen. Direct and continuous measurement of listening has relevance for evaluation of remediation methods and for discovery of variables potentially related to listening.
