IAIA 2016 poster

Poster presentation at IAIA 2016

This poster of a flowchart shows how Organized Reasoning can be introduced into different stages of the IA process.  We also provided a paper describing the background information and reasoning behind the poster, which is in the Proceedings of the conference. Both documents are also available from the International Association for Impact Assessment’s 2016 conference website.

2013 IAIA Conference Calgary Canada

An oral presentation made at the Calgary IAIA 2017 conference described the work Tim Hicks did for his master’s thesis. (GB was his thesis supervisor.) He studied how effectively ‘arguments,’ describing significance determinations, were reached in a government agency’s EA reports. (Result: although the data was present and the conclusions were quite reasonable, the arguments were very weakly presented.) He suggested steps for improvement. The audience handout and PowerPoints are available below, as is the original thesis upon which the presentation is based. (We are working on a journal article summarizing this work. A link will posted here when complete.)
