Here are some examples of trying to impact public policies through the use of advocacy coalitions, and utilizing communicative efforts such as newspapers, the internet, and student issues conventions to facilitate the ideas eventually asserted by the advocacy coalitions.
One involves the revision of the bi-national Great Lakes Water Quality Agreement, first signed in 1972 and rooted in the Boundary Waters Treaty of 1909. Scientists and others used multiple forums to influence the outcome of the debate, including testifying at International Joint Commission events and efforts such as the one below, reported in many online and hardcopy news outlets.
The other was an effort to pass a clean energy initiative in Michigan during the 2012 electoral cycle (the initiative failed, and for context, the right to collective bargaining initiative failed but an emergency manager law was repealed). During a lame duck session of the Michigan legislature in late 2012 and shortly after the reelection of president Obama, a right-to-work law was passed, a newer and initiative-proof emergency manager law emerged, and record setting educational and other policies were literally rammed through the legislature. By June 2013, tens of thousands of people marched down Woodward Avenue from Warren to Hart Plaza to commemorate the 50th anniversary of Dr. King's 1963 march in Detroit, with crowds and speakers advocating chillingly the same issues echoed by Dr. King just 50 short years ago.
Finally, every year (traditionally during a federal electoral cycle) since at least the early 1990s and before, local Community Colleges and Universities have come together to frame a Student Political Issues Agenda, formed and voted on at the Student Political Issues Convention. The Urban Agenda Project, founded by Otto Feinstein at Wayne State University, has lived on in multiple forms, especially through the collaboration of primarily political science faculty at Henry Ford Community College and Oakland Community College. Stay tuned for the 2014 event!
