Dear Pete - Here's a geography book - an unusual, interesting and small book that may inform some of your framework for analysing modelling - Wood, Denis. (1993). The power of maps. New York, Guilford Press. Two classics: Tufte, E. (1983). The visual display of quantitative information. Tufte, E. (1990). Envisioning information. Cheshire, CT, Graphics Press. There's a very very interesting guy in Canada named Alan Thomson working with the Canadian Forest Service on how to ethically model the First Nation's use of their native lands, especially forest lands: athomson@pfc.cfs.nrcan.gc.ca Here's his paper: Thomson & Schmoldt, 2001, "Ethics in computer software design and development" Computers and Electronics in Agriculture 30(2001) 85-102, Elesevier Press. I believe a polite email would get a good response. He's not so much into GIS as analytical modelling (Simile, a clone of Stella). Tell him Denise Rall referred you. Good luck!
