Several recent results pertaining to nonlinear equations of ecology are applied to a generalization of the Turner-Bradley-Kirk-Pruitt (TBKP) equation, which illustrates a variety of interesting possibilities as regards persistence and extinction. The chief novelty consists in exploiting the value set of the equation, that is, the set of values taken on by the solution as t increases from 0 to ∞...

Many applications of autonomous agents require groups to work in tight coordination. To be dependable, these groups must plan, carry out and adapt their activities in a way that is robust to failure and to uncertainty. Previous work developed contingent, temporally flexible plans. These plans provide robustness to uncertain activity durations, through flexible timing constraints, and robustness...

A technical extension is given for the fixed point statement in Kirk and Saliga [Nonlinear Analysis, 47 (2001), 2765-2778].

On April 6, 1963, Samuel A. Kirk told a parent advocacy group that “Recently, I have used the term ‘learning disability’ to describe a group of children who have disorders in development, in language, speech, reading, and associated communication skills needed for social interaction” (Kirk, 1975, p. 9). By 1968, “specific learning disability” (LD) became a federally designated category of speci...
