  • Drawing from ethnographic research in the Latino barrios of North Denver, this article deconstructs the history of one small yet vital public space—la Raza Park. During the 1970s, this place, its pool and the many events it grounded, built community
  • cohesion and fostered cultural identity. In 1981, city authorities went so far as to deploy a SWAT team to la Raza Park to enforce a permit violation. The following summer, they demolished its pool. North Denver is now gentrifying rapidly. This essay

  • Economic geography ; Importation ; Latin America ; Migration ; Perception ; Political geography ; Public opinion ; Remittances ; Trade ; United States of America
  • In this article, we consult surveys from contemporary Latin America and find that various forms of ongoing economic exchange with the United States, trade, aid, migration, and remittances,are the primary influence on mass perception of the northern
  • hegemon and actually promote goodwill, rather than bitterness, toward the United States. Moreover, we demonstrate that the most powerful channel through which economic exchange does so is consumption: inflows of US imports boost pro-American sentiment more
  • than do other forms of exchange. In contrast, the legacy of US imperialism has little resonance in mass beliefs about the colossus of the north.
