Abstract: Prominent assumptions about street homelessness and how it should be addressed originate primarily from middle class domiciled worldviews. This article draws on interviews with 58 street homeless people to develop a typology for explaining different forms of homelessness resulting from differences in class of origin. The concepts of social distance and abjection are used to illustrate how class politics manifests in street homelessness and in responses to this issue. Many of our homeless participants referred to two broad groupings of homeless people who display distinct experiences and cultures in their daily lives on the streets. Drifters are people who do not experience homelessness as a sharp disjuncture from their previously housed life. Street homelessness is a continuation of the hardships of their lower class backgrounds. Droppers are people who have “fallen” on hard times and aspire to return to mainstream middle class lifeworlds. Differentiating between these two groups provides a space for defamiliarizing dominant understandings of, and current generic responses to, homelessness and foregrounds the need for reorienting services to better meet the needs of drifters.  相似文献

Widespread neoliberal-era privatizations in South America's extractive economies rekindled longstanding social movement demands for nationalist control of non-renewable resources and propelled the region's left political turn over the last decade. In Bolivia, where resource extraction has dominated exports since colonial times, social movements employing resource nationalist master frames overturned governments in 1952, 2003, and 2005. In 2005 indigenous leader Evo Morales was elected president promising to direct resource wealth to generate economic development, but the structural constraints created by an extractive economy have made these goals impossible to achieve over the short and medium term. This article suggests that the clash between resource nationalist imaginaries embedded in contentious social movements and the realities of long-term extractive dependent economies not only limits government policy options but also fuels continued social protest.  相似文献

Late modernity is replete with new borders that defy traditional geographic notions of scale. The irruption of such transverse borders is seen by some as signalling a threatening loss of the link between place and identity. Yet others have viewed this as a productive decentring. The Chicano movement and the aesthetic production that arises from it illustrates this productivity. Chicano national identity is actively produced through the revisioning of space that both draws from and defies geopolitical borders. This challenges geographers and other border-based scholars to rethink the ways that borders manage late modern power.  相似文献

Mackness, B.S., Black, K.H. & Price, G.J., 1.10.2014. Occurrence of Euowenia grata (De Vis, 1887 De Vis, C.W. [In Anon.] 1887. Untitled. The Brisbane Courier 9224 (44) (8 August), 6. [Google Scholar]) (Diprotodontidae, Marsupialia) from the Pliocene Spring Park Local Fauna, northeastern Queensland. Alcheringa 39, 000?000. ISSN 0311-5518

Ten specimens including several dentaries and maxillae, recovered from the Pliocene Spring Park Local Fauna, northern Australia, are referred to the diprotodontine Euowenia grata (De Vis). The fossils exhibit minimal dental wear and reveal new characters that are unrecognizable in the holotype. The remains represent at least three animals, effectively doubling the previous number of individuals known for this rare megaherbivore. The new records also provide a significant northern geographic range extension for the species and allow an assessment of intraspecific variation, sexual dimorphism and phylogenetic relationships for the species. Euowenia grata is most similar in morphology to the monotypic Pliocene diprotodontid Meniscolophus mawsoni.

Carlos Fuentes's 1987 carnivalesque novel, Cristóbal nonato, criticizes Mexico's prehispanic past through a satire of Tenochtitlán-Mexico City in the neoliberal, postnational era. This study consequently juxtaposes criticism, theory, and analysis from both imperial Aztec Mexico and nationalist modern Mexico. While the bulk of this 600-page novel confronts readers with a highly negative (although often risible) view of both Mexicos, it ultimately leads to a happy ending with a didactic twist: If Mexicans will stop abandoning Mexico for the North or other green pastures, and instead stay in Mexico despite its many problems, they can turn things around by their altruism and their activist determination.  相似文献

Strontium isotope analysis is applied in South America for the first time in order to investigate residential mobility and mortuary ritual from ad 500 to 1000. While Tiwanaku‐style artefacts are spread throughout Bolivia, southern Peru and northern Chile during this time, the nature of Tiwanaku influence in the region is much debated. Human skeletal remains from the site of Tiwanaku and the proposed Tiwanaku colony of Chen Chen have been analysed to test the hypothesis that Tiwanaku colonies, populated with inhabitants from Tiwanaku, existed in Peru. Strontium isotope analysis supports this hypothesis by demonstrating that non‐local individuals are present at both sites.  相似文献

Strontium isotope analysis of bone and tooth enamel from prehistoric human skeletons is an important new technique used to address questions regarding migration. Two problems arise in such investigations: (1) levels of strontium isotope ratios in local bedrock, soil, water, plants and animals are variable; and (2) a range of values in human bone and enamel data make it difficult to distinguish some migrants from locals. Analysis of the bones of small animals provides a robust measure of local strontium isotope ratios and a reliable, if conservative, means for determining confidence limits for distinguishing migrants. Data from various geographical areas are presented here in a discussion of variability in strontium isotope values. Examples are provided using modern and prehistoric materials. We conclude with the recommendation that studies involving strontium isotope analysis should incorporate small animal samples for comparative purposes whenever possible.  相似文献

The purpose of this study was to chemically and texturally characterize ceramic oil jar sherds from North Carolina Shipwreck 31CR314 and to explore the utility of environmental scanning electron microscopy/X-ray energy dispersive spectrometry (SEM/EDS) for that purpose. The oil jar sherds, widely dispersed about Shipwreck 31CR314, are morphologically similar to each other, which suggests they could be from a single jar, but with so few joins this could not be concluded with certainty. Therefore, an aim of this study was to investigate whether chemical or textural characterization of the sherds might reveal unique attributes that could distinguish individual jars; results of characterization perhaps could give information on their origin and possibly site formation processes, such as whether environmental forces could have scattered sherds of a single jar during and after sinking of the ship. Previous studies have indicated this shipwreck is likely the remnants of the Queen Anne's Revenge, flagship of the pirate Blackbeard. Sherds from this shipwreck were compared with similar oil jar sherds excavated from a land site, Brunswick Town, North Carolina, to explore the use of composition and texture as hallmarks. The chemical components of the artifacts were determined by SEM/EDS. This method of analysis is valuable for archaeological research because it is rapid and non-destructive to the ceramic artifacts. Both groups of lead-glazed coarse red earthenware sherds were texturally similar except for the glazed sides of all 31CR314 sherds that exhibited small tracks of unique crescent-shaped marks. These marks may be due to manufacturing effects and immersion in seawater, and the marks may serve as hallmarks for individual jars or potentially individual manufacturers. The sherds were generally similar in composition, but the two groups exhibited distinct differences. Brunswick Town sherds consistently contained more phosphate on unglazed sides, an average 1.46 wt.% P2O5, and also contained trace elements not detected in the Shipwreck 31CR314 sherds. These distinct differences could be due to different manufacturing origins for Shipwreck 31CR314 and Brunswick Town ceramics but also could reflect their subjection to different environments during use and loss prior to archaeological recovery.  相似文献

Ethnoarchaeological research at highland Maya hunting shrines documents the material remains of interactions between two types of animate beings: humans and the forest. When either active agent enters the others’ domain there are accompanying ceremonial activities to assuage the inherent danger, often leaving physical traces in the material record. These traces, if found in the archaeological record, might reveal similar ancient interactions. Using the material correlates of modern hunting rituals, we explore the utility of ethnoarchaeological research in identifying negotiations with non-human agents associated with the animate forest – an active agent in many societies.  相似文献
