Signaling networks are exemplified by systems as diverse as biological cells, economic markets, and the Web. After a discussion of some general characteristics of signaling networks, this paper explores the adaptive evolution of complexity in a simple model of a signaling network. The paper...

I consider the research university from a complex adaptive systems perspective, and offer some modest proposals for the university of the future-a student-based complex adaptive learning community in which both feedback and transdisciplinary problem-oriented Centers play central roles. <p> <p> To...</p></p>

It is sometimes thought that philosophers have little to offer those who think about the science of complex systems. There are, however, two philosophical ideas that seem crucial in considering the very definition of complexity. The first is the distinction between "ontology" and "epistemology",...

Theoretical studies of the stability of food webs have generally not incorporated space as a contingency affecting coexistence of species. Here, I considered the importance of spatial heterogeneity on the stability of an individual-based food web model. Individual agents diffused on a lattice of...

This paper is divided into four parts. The first section (I.) consists of definitions which center on the concept of complexity. As a minimum, the terms, system, complexity, and adaptation as used in this paper need an explanation. The second section (II.) is a sketch of cultural complexity in...
