Systems theory existed before the appearance of complexity theory. However, the idea of complexity has been around for a long time. Thus, in effect there may be older and newer versions of complexity theory. Regardless of whether complexity is viewed as a new or an old concept in economics,...
What Is Complexity? It would require many different concepts to capture all our notions of the meaning of complexity. The concept that comes closest to what we usually mean is... M Gell-Mann - 《Complexity》 被引量: 689发表: 2002年 What Is Complexity? It would require many different conce...
Debate about the appropriate means to assess the effects of complex public health interventions is very much ongoing, particularly the feasibility and value of randomised controlled trials. There has been little systematic investigation of complexity in studies of public health interventions, but an appro...
What is complexity? The more the information is necessary to fully describe a system, the more complex it is. If we can describe the entire system in a few sentences, it is simple; if we need sever...
Such explanation of complexity is obviously vague and offers no discriminating criterion which would allow one to classify any given system into one of the two categories: complex or simple. Since the middle of the 20th century, there have been many attempts to define a quantity which could ...

This paper considers questions of continuity and change in education from the perspective of complexity theory, introducing the field to educationists who might not be familiar with it. Given a significant degree of complexity in a particular environment (or ‘dynamical system’), new properties and...
The information content in a rainfall-runoff record is sufficient to support models of only very limited complexity (Jakeman and Hornberger, 1993). This begs the question of what limits should observed data place on the allowable complex... RJ Abrahart,DJ Beriro - 《Egu General Assembly》 被...
