The Problem of Relevant Detaild characterizations of classical interest. This conference, in honor of Kenneth Cooke and his contributions to theories involving age structure, social structure, and delays, is testament to the modern trend, and to the recognition that simplistic theories that ignore population structure often are seriously flawed in their predictions.

The Red Atlantic: Travelling DebatesWe derive general models for the interaction of unilingual and bilingual components of a population, and classify those models for which the dynamics is trivial by obtaining criteria for the nonexistence of periodic solutions.

Antibacterial Coatings on Medical ImplantsIn this paper, we establish conditions under which solutions of . will be bounded. This partially answers the open questions proposed by this author in his recent works on neutral predator-prey and competition systems.

Antimicrobial Materials in ArthroplastyExamples of nonstationary populations of constant size are explicitly constructed. Necessary and sufficient conditions for a constant birth function are established under mild restrictions on the death rate and the initial distribution and examples are provided.

Convergence to Equilibria in General Models of Unilingual-Bilingual InteractionsWe derive general models for the interaction of unilingual and bilingual components of a population, and classify those models for which the dynamics is trivial by obtaining criteria for the nonexistence of periodic solutions.

Stability Change of the Endemic Equilibrium in Age-Structured Models for the Spread of S—I—R Type InAge-structured endemic models of . → . → . type can exhibit a stability change for the endemic equilibrium if the rate of a susceptible individual to be infected by an infective individual does not depend of the age of the susceptible individual, but is highly concentrated in a particular age class of the infectives.
