This article introduces a model that harnesses praxis as a powerful tool for critique, knowledge, and action within the realm of public archaeology. The adopted framework focuses on persistence as a middle-range methodology that bridges the material past to activist and collaborative-based projects. Recent research at Mission La Purísima Concepción in Lompoc, California, shows the effectiveness of this model and its real-world application. Visitors to California missions encounter the pervasive “Mission Myth”—a narrative that systematically overlooks and marginalizes Indigenous presence while perpetuating ideas of White hegemony and Eurocentrism. Archaeological excavations in the Native rancheria and collaboration with members of the Chumash community help resist notions of Indigenous erasure. By activating notions of persistence through public archaeology, this study contributes to dismantling entrenched terminal narratives, paving the way for a more accurate representation of the past and fostering a more inclusive archaeological practice.

This paper offers a historical examination of the ways in which advocacy strategies and tactics have shifted in relation to political opportunities, using a case study of a hydroelectric dam project in the Brazilian Amazon, known as the Belo Monte Dam. Drawing on over three decades of resistance by transnational activist coalitions, the paper looks at how new tactics and political alignments have altered the dynamics of activism and norm diffusion in Brazilian domestic environmental, human rights and development policies. The paper argues that current theories of norm diffusion inadequately explain backslides and tend to underestimate the complexity of domestic political alignments. The case adds political insight to our understanding of the relationship of transnational advocacy strategy to environmental and human rights political realities in Brazil.
