Eemian landscape response to climatic shifts and evidence for northerly neanderthal occupation at a palaeolake margin in northern germany

The prevailing view suggests that the Eemian interglacial on the European Plain was characterized by largely negligible geomorphic activity beyond the coastal areas. However, systematic geomorphological studies are sparse. Here we present a detailed reconstruction of Eemian to Early Weichselian landscape evolution in the vicinity of a small fingerlake on the northern margin of the Salzwedel Palaeolake in Lower Saxony (Germany). We apply a combination of seismics, sediment coring, pollen analysis and luminescence dating on a complex sequence of colluvial, paludal and lacustrine sediments. Results suggest two pronounced phases of geomorphic activity, directly before the onset and at the end of the Eemian period, with an intermediate period of pronounced landscape stability. The dynamic phases were largely driven by incomplete vegetation cover, but likely accentuated by fluvial incision in the neighbouring Elbe Valley. Furthermore, we discovered Neanderthal occupation at the lakeshore during Eemian pollen zone (PZ) E IV, which is chronologically in line with other known Eemian sites of central Europe. Our highly‐resolved spatio‐temporal data substantially contribute to the understanding of climate‐induced geomorphic processes throughout and directly after the last interglacial period. It helps unraveling the landscape dynamics between the coastal areas to the north and the loess belt to the south

Racialization and Reproduction: Asian Immigrants and Californias Twentieth-Century Eugenic Sterilization Program.

During the twentieth century, state health authorities in California recommended sterilization for over 20,000 individuals held in state institutions. Asian immigrants occupied a marginalized position in racial, gender, and class hierarchies in California at the height of its eugenic sterilization program. Scholars have documented the disproportionate sterilization of other racialized groups, but little research exists connecting the racist, gendered implementation of Asian immigration restriction to the racism and sexism inherent in eugenics. This study examines patterns of coercive sterilization in Asian immigrants in California, hypothesizing higher institutionalization and sterilization rates among Asian-born compared with other foreign- and US-born individuals. We used complete count census microdata from 1910 to 1940 and digitized sterilization recommendation forms from 1920 to 1945 to model relative institutionalization and sterilization rates of Asian-born, other foreign-born, and US-born populations, stratified by gender. Other foreign-born men and women had the highest institutionalization rates in all four census years. Sterilization rates were higher for Asian-born women compared with US-born [Incidence Rate Ratio (IRR) = 2.00 (95% CI: 1.61, 2.48)] and other foreign-born women (p < 0.001) across the entire study period. Sterilization rates for Asian-born men were not significantly higher than those of US-born men [IRR 0.95 (95% CI 0.83, 1.10). However, an inflection point model incorporating the year of sterilization found higher sterilization rates for Asian-born men than for US-born men prior to 1933 [IRR 1.31 (95% CI 1.09, 1.59)]. This original quantitative analysis contributes to the literature demonstrating the health impact of discrimination on Asian-Americans and the disproportionate sterilization of racial minorities under state eugenics programs

Incisions closely followed by rising water tables. Long‐lasting phase of geomorphic stability in the mid‐Eemian, characterized by: very dense forest cover. the formation of a fingerlake within the paleochannel with gradually sinking water table. no influx of clastic sediments, but deposition of peat and lake‐marl deposits.Max‐Planck‐Gesellschaft http://dx.doi.org/10.13039/50110000418
