Este trabajo analiza diversos aspectos sobre la formación y el desarrollo de la filial de Abuelas de Plaza de Mayo en la ciudad de Rosario, la cual tiene la particularidad de haber sido fundada y sostenida únicamente durante mucho tiempo por su fundadora, Darwinia Galicchio, quien recuperó a su nieta Ximena en un lento proceso que comenzó en el año 1984. Además, la formación de Abuelas en Rosario ha sido casi paralela a la de la delegación de Madres de Plaza de Mayo en dicha ciudad. Ambas organizaciones tuvieron su origen en Familiares de Detenidos y Desaparecidos por Razones Políticas y Gremiales de Rosario. Darwinia integró los tres organismos. En este marco, el artículo se propone indagar este caso en particular desde la perspectiva regional pero a la vez incorporando la dimensión de la historia de vida

El trabajo indaga la construcción de normativas de género sobre la mujer que se erigieron desde el discurso médico. Para ello, desde una perspectiva relacional de análisis, examinamos las intervenciones de diversas posiciones del campo médico. Sus variados posicionamientos político-ideológicos, sus relaciones sociales y sus diferentes espacios de acción son inflexiones relevantes para comprender cómo se solaparon o diferenciaron en torno a las construcciones de los roles sociales en el ámbito local. Las narrativas dominantes ligaron la feminidad a la maternidad y las intervenciones marginales, provenientes de médicos anarquistas, tensionaron aquellas conceptualizaciones y promovieron ideas emancipatorias

High-resolution records of opal, carbonate, and terrigenous fluxes have been obtained from a high-sedimentation rate core (MD84-527: 43°50'S; 51°19'E; 3269 m) by normalization to 230Th. This method estimates paleofluxes to the seafloor on a point-by-point basis and distinguishes changes in sediment accumulation due to variations in vertical rain rates from those due to changes in syndepositional sediment redistribution by bottom currents. We also measured sediment delta15N to evaluate the changes in nitrate utilization in the overlying surface waters associated with paleoflux variations. Our results show that opal accumulation rates on the seafloor during the Holocene and stage 3, based on 14C dating, were respectively tenfold and fivefold higher than the vertical rain rates, At this particular location, changes in opal accumulation on the seafloor appear to be mainly controlled by sediment redistribution by bottom currents rather than variations in opal fluxes from the overlying water column. Correction for syndepositional sediment redistribution and the improved time resolution that can be achieved by normalization to 230Th disclose important variations in opal rain rates. We found relatively high but variable opal paleoflux during stage 3, with two maxima centered at 36 and 30 kyr B.P., low opal paleoflux during stage 2 and deglaciation and a pronounced maximum during the early Holocene, We interpret this record as reflecting variations in opal production rates associated with climate-induced latitudinal migration of the southern ocean frontal system. Sediments deposited during periods of high opal paleoflux also have high authigenic U concentrations, suggesting more reducing conditions in the sediment, and high Pa-231/Th-230 ratios, suggesting increased scavenging from the water column. Sediment delta15N is circa 1.5 per mil higher during isotopic stage 2 and deglaciation. The low opal rain rates recorded during that period appear to have been associated with increased nitrate depletion. This suggests that opal paleofluxes do not simply reflect latitudinal migration of the frontal system but also changes in the structure of the upper water column. Increased stratification during isotopic stage 2 and deglaciation could have been produced by a meltwater lid, leading to lower nitrate supply rates to surface waters.
