Gender, power, and mobility among the Awá-Guajá (Maranhão, Brazil) by Hernando, Almudena, Politis, Gustavo Gabriel, González Ruibal, Alfredo, Beserra Cohelo, Elizabeth

“…The aim of this paper is twofold: (1) to argue that, in otherwise "egalitarian" societies, the differences in physical mobility involved in the complementary tasks carried out by men and women may account for gender inequality on the symbolic domain, given that mobility is a key factor in the construction of personhood in contexts of "relational, "non-individualized identity; and (2) to check the validity ofthat assumption in the light of fieldwork data about gender relationships among the Awá-Guajá.…”

“…In the late nineteenth and early twentieth centuries Florentino Ameghino initiated the debate on the antiquity of humans in the Argentinean Pampas, which has been reviewed recently due to new radiocarbon dates obtained. Morphometric analyses from these Argentinean Pampas samples are presented together with early samples from Chile, Brazil, and Colombia. …”

An approach to prehispanic diets in the pampas during early/middle Holocene by Politis, Gustavo Gabriel, Scabuzzo, Clara, Tykot, Robert

“…Isotopic values from archaeofauna – including megafauna and current fauna – are also reported. d13CCOL isotopic values on human remains from these sites suggest the existence of different diets in Early-Middle Holocene groups, including individuals consuming mainly marine resources, individuals with a terrestrial diet based on C3 plants and/ or the intake of C3-consuming herbivores, and finally, individuals with a mixed diet. d13CCOL data from human remains are consistent with the isotopic results obtained for the most abundant faunal remains at the sites (guanaco, Pampean deer, and seal). …”

Análisis de los artefactos líticos del sitio Arroyo Seco 2 (Área Interserrana Bonaerense, Argentina), identificación petrográfica y posibles fuentes de aprovisionamiento by Barros, Maria Paula, Blasi, Adriana Mónica, Politis, Gustavo Gabriel

“…Los estudios realizados muestran que las rocas analizadas provienen de distintos afloramientos primarios y secundarios de la subregión Pampa Húmeda, situados en diferentes sectores de las sierras de Ventana, Tandilia, en la cuenca de Claromecó (área Interserrana) y en los depósitos de la costa Atlántica. Estos datos sirvieron para corroborar y profundizar, por un lado las características litológicas de las rocas explotadas en el sitio y por otro lado, las propuestas sobre el origen, selección, modos de aprovisionamiento y trayectorias de circulación llevadas a cabo por los grupos para la obtención de las distintas rocas desde el Pleistoceno tardío.…”
