The document discusses four models of macro practice: locality development, social planning, social action, and references. It provides details on two examples: 1) The Stan Musial Bridge project in St. Louis which created jobs, increased property values and commercial development, reduced congestion, and connected two states. 2) The Collective Impact initiative in East St. Louis which brings together service providers, community members, and experts to address community problems through the Ready by 21 Forums model. It also briefly discusses the Occupy Wall Street movement and some of the changes it helped spur in the financial industry such as blocking debit card fees and increasing transfers to local banks and credit unions.
