This editorial theorizes the spatialization of black gender and sexual minorities. We examine the ways in which race, gender, and sexuality work to complicate the geographies of black gender and sexual marginality. Drawing on insights from Foucault's theory of heterotopia, we develop the concept of anti-black heterotopias to understand the spatial ordering of black gender and sexuality within the larger geographies of black people. We contend that if anti-black racism forces black people to live within contained landscapes that exist on the margins of whiteness, then black gender and sexual minorities, who are subject to violence and public ridicule, live in a placeless space, a location with no coordinates. In other words, the heterosexism/homophobia toward black gender and sexual minorities that is expressed in socio/spatial terms is complicit with the spatialization of anti-black racism. We also use anti-black heterotopias as a way to situate the eight articles in parts 1 and 2 of this themed section, as well as to highlight the theoretical linkages between them.  相似文献

The articles in part 2 of the themed section Gender and Sexual Geographies of Blackness focus on the creation of new cartographies of resistance, struggle, and survival in which black gender and sexual minority communities are engaged. Using black feminist readings of gender, sexuality, and geography as a point of departure, we consider the complex challenges that black gender and sexual minorities pose to conventional feminists and queer readings of space. These articles map unexplored sites of black struggle, resistance, and survival where black gender and sexual minorities confront marginalization and create new spaces of sociality, community, desire, pleasure, support, and love.  相似文献

The protocol of preparation of keratinized samples (e.g. hair, furs …) for radiocarbon dating that we have developed is based on the selective extraction of keratin from the bulk part of the shaft (cortex). The aim of this method is to eliminate the cuticle which could contain exogenous carbon from external contaminations. The total treatment takes place as follows: a washing/dry cleaning, a soft treatment with diluted acidic and basic solutions (acid/alkali/acid method) similar to the protocol used for vegetal samples, extraction of keratin by reduction using dithiothreitol and precipitation with sodium deoxycholate and trichloroacetic acid. This method was applied on a hair sample from an Andean mummy, conserved in the collections of the Anthropology Laboratory of the National Museum of Natural History (Musée de l’Homme) in Paris, France. The results of two runs reveal that the mummy is dated to a period between the eleventh century and the first half of the twelfth century. It therefore belongs to the Late Intermediate period (900–1450?ad). The combination of historical research, the study of the body by computed tomography and the analysis of mineral deposits on the surface of the body provides clues to identify the geographical origin of the mummy. These investigations led to determine that the mummy comes from the region of Tarapacá in Chile and belongs to the cultural complex Pica-Tarapacá.  相似文献

Active adult, age-restricted communities are significant to urban history and city planning. As communities that ban the permanent residence of children under the age of nineteen with senior zoning overlays, they are unique experiments in social planning. While they do not originate the concept of the common interest community with its shared amenities, the residential golf course community, or the gated community, Sun Cities and Leisure Worlds do a lot to popularize those physical planning concepts. The first age-restricted community, Youngtown, AZ, opened in 1954. Inspired by amenity-rich trailer courts in Florida, Del Webb added the “active adult” element when he opened Sun City, AZ, in 1960. Two years later, Ross Cortese opened the first of his gated Leisure Worlds. By the twenty-first century, these “lifestyle” communities had proliferated and had expanded their appeal to around 18 percent of retirees, along with influencing the design of intergenerational communities.  相似文献

The emergence of archaeological interest in native copper in the mid-1800s developed in concert with explanations that privileged the Lake Superior area over other potential sources of copper. Most scholars have thus assumed that when copper artifacts first appeared in Northeastern North America, they arrived as finished implements or were locally made from Lake Superior raw materials. Procurement models that point to Lake Superior as the sole source of native copper have been widely accepted in the absence of systematic large-scale testing. This article evaluates the dominant model for native copper procurement and presents trace element data derived from instrumental neutron activation analysis (INAA) to determine whether hunter-gatherers in the Northeast utilized one dominant source of copper or in fact exploited a number of geological deposits. I specifically report on the chemical characterization of copper from 13 discrete geological deposits and 18 archaeological sites dating to the Late Archaic (ca. 5000–3000 B.P.) and Early Woodland (ca. 3000–2000 B.P.) periods to suggest that the dominant model for native copper procurement is oversimplified.  相似文献
