The document discusses several case studies of participatory policy-making initiatives:
1) Regulations.gov - A US government portal that allows public commenting on proposed rules. It has improved access and participation in the rulemaking process.
2) A partnership between community colleges and regional planning agencies that engaged "hard to reach" groups in transportation planning through student facilitators. This reduced costs while making participation more inclusive.
3) The Citizens' Initiative Review in Oregon, where citizen panels review ballot measures and provide impartial summaries to voters. Research found it was an effective way to inform voters.
