We evaluate whether John Holland's Echo model exemplifies his theory of complex adaptive systems. After reviewing Holland's theory of complex adaptive systems and describing his Escho model, we describe and explain the characteristic evolutionary behavior observed in a series of Echo model runs. We conclude that Echo lacks the diversity of hierarchically organized aggregates that typify complex...

After it is argued that philosophers of science have lost their interest in logic because they applied the wrong type of logics, examples are given of the forms of dynamic reasoning that are central for philosophy of science and epistemology. Adaptive logics are presented as a means to understand and explicate those forms of reasoning. All members of a specific (large) set of adaptive logics ar...

Purpose The purpose of this paper is to consider why entrepreneurship theorising has become fragmented and how we might resolve the research problem. Design/methodology/approach We first examine how entrepreneurial constructs reflect only part of what we “mean” by the construct to argue that we use different social constructions. This explains why theories are fragmented. But we then ask how we...

Quantitative researching on the degree of incidence between the logistics industry and relevant macroscopic system elements is the basis of reasonable and scientific policy on industrial development. In the light of the macro-level, the logistics industry system is consisted of multiple macroscopic agents such as macro-economic, infrastructure, social environment, market demanding, the traditio...

Supporting the early phases of design requires, among others, support for the specification and use of multiple and evolving representations, and for the exchange of information between these representations. We consider a complex adaptive system as a model for the development of design representations, and present a semi-constructive algebraic formalism for design representations, termed sorts...

Purpose: Integrated health and social care is necessarily complex since the competence needed for carrying out the task of care does not lie within one individual provider organization, but requires deliberate co-operation between different providers. In this world, the primary managerial task is variously seen as seeking the efficient administration of human and material resources, and achievi...

in this paper, we introduce a new hyperchaotic complex t-system. this system has complex nonlinear behavior which we study its dynamical properties including invariance, equilibria and their stability, lyapunov exponents, bifurcation, chaotic behavior and chaotic attractors as well as necessary conditions for this system to generate chaos. we discuss the synchronization with certain and uncerta...

Epistemologically speaking, second language acquisition research (SLAR) might be reconsidered from a complex dynamical system view with interconnected aspects in the ecosystem of language acquisition. The present paper attempts to introduce the tenets of complex system theory and its application in SLAR. It has been suggested that the present dominant traditions in language acquisition research...
