"This article explores the uses of sources in coverage of the COVID-19 pandemic in social media posts of mainstream news organizations in Brazil, Chile, Germany, Mexico, Spain, the U.K., and the U.S. Based on computational content analysis, our study analyzes the sources and actors present in more t ... han 940,000 posts on COVID-19 published in the 227 Facebook, Instagram, and Twitter accounts of 78 sampled news outlets between January 1 and December 31 of 2020, comparing their relative importance across countries, across media platforms, and across time as the pandemic evolved in each country. The analysis shows the dominance of political sources across countries and platforms, particularly in Latin America, demonstrating a strong role of the state in constructing pandemic news and suggesting that mainstream news organizations' social media posts maintain a strong elite orientation. Health sources were also prominent — consistent with the defining role of biomedical authority in health coverage—, while significant diversity of sources, including citizen sources, emerged as the pandemic went on. Our results also revealed that the use of specific sources significantly varied over time. These variations tend to go hand in hand with specific global milestones of the pandemic." (Abstract) more

"Since1993 to the present, a group of Mapuche activists hasaired the bilingual radio shot Wixage anai! in Santiago, Chile; on the other side of the Andes, another Mapuche collective, the Equipo de Comunicación Mapurbe, produced and broadcast a series of brief radio programs between 2003 and 2005 in ... Bariloche, southern Argentina. In this article, I argue that these radio programs constitute an exercise of Mapuche agency that challenges what I call the acoustic colonialism of corporate and criollo mass media in both countries. This article illustrates how Mapuche activists creatively use radio as a connective medium among Mapuche communities and a space for the public audibility of their own voices, sounds, and modes of speech. I analyze the history, cultural politics, and performative features of these two initiatives, engaging theoretical and critical views on sound media, state cultural policies, and politics of indigenous agency."
