First published as Systems Ecology in 1983, Ecological and General Systems proposes principles of self-organization and the designs that prevail by maximizing power and efficiency. Comparisons to fifty other systems languages are provided. Innovative presentations are given on earth homeostasis (Gaia); the inadequacy of presenting equations without network relationships and energy constraints; the alternative interpretation of high entropy complexity as adaptive structure; basic equations of ecological economics; and the energy basis of scientific hierarchy.
Part I introduces energetics, hierarchy, and systems modeling. Part II features design elements: intersections, autocatalytic modules, loops, series, parallel elements, and webs. Part III includes embodied energy, spectra of energy quality, temperature, complexity, spatial distribution, and diversity. Part IV discusses production, consumption, ecosystems, succession, economic systems, anthropological models, urban and regional models, global biogeochemistry, and the universe.
Mediated modeling is an innovative new approach that enhances the use of computer models as invaluable tools to guide policy and management decisions. Rather than having outside experts dispensing answers to local stakeholders, mediated modeling brings together diverse interests to raise the shared level of understanding and foster a broad and
deep consensus. It provides a structured process based on system dynamics thinking in which community members, government officials, industry representatives, and other stakeholders can work together to produce a coherent, simple but elegant simulation model.
Mediated Modeling by Marjan Van Den Belt is a practical guide to participatory modeling for both practitioners and students, one that is firmly theoretically grounded in the field of systems dynamics and environmental modeling. Five in-depth case studies describe the successful use of the technique in a variety of settings, and a final chapter synthesizes the lessons highlighted by the case studies.
Mediated Modeling's step-by-step description of the techniques and practical advice regarding implementation offer a real-world solution for all those seeking to make sound decisions about the environment.
At an ecopark in Mexico, tourists pretend to be illegal migrants, braving inhospitable terrain and the U.S. Border Patrol as they attempt to cross the border. At a living history museum in Indiana, daytime visitors return after dark to play fugitive slaves on the Underground Railroad. In the Mojave Desert, the U.S. Army simulates entire provinces of Iraq and Afghanistan, complete with bustling villages, insurgents, and Arabic-speaking townspeople, to train soldiers for deployment to the Middle East. At a nursing home, trainees put on fogged glasses and earplugs, thick bands around their finger joints, and sandbag harnesses to simulate the effects of aging and to gain empathy for their patients.
These immersive environments in which spectator-participants engage in simulations of various kinds—or “simming”—are the subject of Scott Magelssen’s book. His book lays out the ways in which simming can provide efficacy and promote social change through affective, embodied testimony. Using methodology from theater history and performance studies (particularly as these fields intersect with cultural studies, communication, history, popular culture, and American studies), Magelssen explores the ways these representational practices produce, reify, or contest cultural and societal perceptions of identity.
