Civic Ecology: Living Community Systems For Sustainability, Tim Smith
Systems Science Friday Noon Seminar Series
Civic Ecology is a stakeholder-driven, whole systems framework for creating sustainable communities. The framework focuses on empowering citizens of all ages, cultures, and abilities to envision, create, and manage their community’s unique “software” -- the integrated energy, nutrient, water, waste, material, and food systems, as well as economic flows and cultural interactions that animate their place. Exploring and supporting these flows allows communities to enhance their local wealth (environmental, economic, and social), resilience, and competitiveness, and help them take control of designing and managing their future through collaboration and innovation. The Civic Ecology framework can be the foundation upon which …

Reconstructability Analysis Of Elementary Cellular Automata, Martin Zwick, Hui Shi
Systems Science Friday Noon Seminar Series
Reconstructability analysis is a method to determine whether a multivariate relation, defined set- or information-theoretically, is decomposable with or without loss (reduction in constraint) into lower ordinality relations. Set-theoretic reconstructability analysis (SRA) is used to characterize the mappings of elementary cellular automata. The degree of lossless decomposition possible for each mapping is more effective than the λ parameter (Walker & Ashby, Langton) as a predictor of chaotic dynamics.
Complete SRA yields not only the simplest lossless structure but also a vector of losses of all decomposed structures, indexed by parameter, τ. This vector subsumes λ, Wuensche’s Z parameter, and Walker …

This field guide is the outgrowth of several years experience conducting field courses in conservation and environment and the recognition that little has been prepared for this area through which thousands of Oregonians travel each year, particularly during the summer season.
