A new pentacyclic triterpene acid, elliptic acid was isolated from the ethanolic extract of the leaves of Rubus ellipticus. On the basis of physical evidences coupled with chemical investigations, the structure of elliptic acid was given as, 3,7, 11-trihydroxy ursolic acid.

Group cohesiveness has been one of the most important issues in the study of group dynamics. Most studies on group cohesiveness, however, have concentrated on specific investigations exploring the relationships between certain selected variables in a static mode. For example, one study examines how the degree of member similarity affects the degree of cohesiveness (Terborg, et al., 1976).(omitted)
