“visual cues offer the first indication of a site’s significance” (Ewing)
“the installations trigger memorial operations in the mind, thereby facilitating a personal assimilation of history” (Ewing)
“perception of the site shifts in the experience of the artists’ interventions” (Ewing)
These three quotes seem to offer implications for conventions, though the author is specifically talking about transitory art installations.
