AbstractThe global banking system can be shown to be a Complex Adaptive System that exhibits phase transitions from time to time. These phase transitions can result in significant financial losses to the community that we estimate to be much more significant than losses occurring during “business as usual” periods. In this paper, we argue that the significant losses arising from phase transitions in the banking system requires a very different approach to regulation than the current Basel regime, and that there is a need to transition the Basel regime from a Federation of Systems to a System of Systems. We demonstrate that the World Health Organisation’s recent management system for pandemics is ideally suited for management of the global banking system and would have greater potential to control the phase transition losses than the current Basel system.

Based on isomorphic considerations, this paper attempts to establish an entrepreneur as complex adaptive system, which is one of the concepts that appear prominently in the field of complexity sciences. The attempt to equate the notion of an entrepreneur with the idea of a complex adaptive system, presupposes recognition of the entrepreneur’s role in adaptive agency. Along with this recognition, comes the convenience of contextualizing the concepts of phase transitions and bifurcation points in terms of venture emergence. The dynamics of these concepts are however more commonly explored within the workings of complex or dynamic physical systems. Yet, the broad applicability of the underlying ideas offers the possibility of identifying similar concepts in biological systems and by extension, the field of entrepreneurial cognition and behavior. Thus, the paper adopts an interdisciplinary approach and employs retroductive reasoning in the assemblage of relevant ideas, sought from diverse literary sources. The outcome is a conceptual framework, which presents certain propositions that offer implication for action.

In addition to understanding small-scale societies in their own right "from a complex systems perspective" (Boekhorst and Hemelrijk this volume), workshop participants expressed a goal of using insights about the dynamics of small-scale societies to better understand the "evolution of state-like structures" (Small this volume), or "the 'emergence' trajectories by which a smallscale society, in its environment, may move autonomously from relatively simple (distributed, no ranking or centralized decision making) to complex (ranking/hierarchy, with centralized decision making and a degree of specialization)" (Doran this volume). Small-scale societies are seen as "preceding conditions" to the development of "rank vs. egalitarian ideologies" (Wright this volume) such as are found in archaic states. Ancient Egypt is a salient example of such an archaic state. In the comparative study of civilizations, ancient Egypt has stood out as the quintessence of a centralized nation-state ruling a large territory. Egyptologists often operate through a vision of ancient Egyptian society, whether explicit or assumed, as highly absolutist. Pharaoh's control of society is complete, effected through an invasive and pervasive centralized bureaucracy. Anthropologists, taking their cue from Egyptologists, see Egypt as one of the earliest examples of a unified nation-state, with a redistributive economy centrally administered over the entirety of the Egyptian Nile Valley. I offer a prospectus for approaching Egyptian civilization as a complex adaptive system (CAS) based on loose analogies with concepts of emergent order and self-organization. This a narrative exploration of ways that ancient Egyptian society may be amenable to the kind of agent-based modeling applied to small-scale societies. Although I recognize that in discussions of "complexity theory" there is nothing close to unanimity or an agreed paradigm (Wilson 1998), some of the more general concepts may at least offer insightful new ways to view social complexity in Egypt. My prospectus is a workin- progress. My sources for complex systems studies are "the literature of metaphor (e.g., Cowan et al. 1994), and the popularizations of metaphysics"; that is to say, what follows is most certainly in Morowitz's (1998) category of meta-metaphor (and I will try to refrain from "word magic").
