Emergence, self organization and self-assembly are concepts wildly used in complex systems theory and by extension in social-ecological studies literature. However, they are seldom clearly defined and they are taken for granted in most of the SES literature. Fortunately, two 2008 articles from Julienne D. Halley currently at Oxford and David A. Winkler tackle the issue and they can be read as fresh as when they appeared. How could I have missed this? You can find the article on emergence here, and on self-organization here.
