Isotopic and technological variation in prehistoric Southeast Asian primary copper production

The ‘Southeast Asian Lead Isotope Project’ (SEALIP) is intended to provide reliable geochemical proxies for late prehistoric through early historic (2nd/1st millennium BCE and 1st millennium CE) local, regional, and inter-regional social interactions, in an archaeological arena lacking established ceramic typologies with which to cross modern national boundaries. We present lead isotope characterisations of the three currently known Southeast Asian prehistoric primary (mining/smelting) copper production centres: Phu Lon and the Khao Wong Prachan Valley in Thailand, and the recently discovered Xepon complex in Laos. Kernel Density Estimation shows that these production centres can be clearly distinguished isotopically, as such fulfilling the core tenet of the ‘Provenance Hypothesis’ (Wilson and Pollard, 2001: 508) and permitting SEALIP to proceed as a research programme tracing regional copper/bronze/lead exchange and provenance patterning. In addition we provide a provisional technological reconstruction of copper smelting processes at Phu Lon to complement our more established understanding of the Khao Wong Prachan Valley. Combined lead isotope and technological datasets allow us to tentatively identify trends in the evolution of Southeast Asian metal technologies and of regional social perceptions of metal exchange.     

Agricultural potential and actualized development in Hawai’i: an airborne LiDAR survey of the leeward Kohala field system (Hawai’i Island)

Archaeological investigations of Hawaiian agriculture have relied on relatively coarse-grained data to investigate archipelago-wide processes, or on fine-grained data to examine patterning within localized zones of agricultural production. These trade-offs between spatial coverage and data resolution have inhibited understanding of both spatial patterns and temporal trends. Our analysis of 173 km² of high-resolution airborne Light Detection and Ranging (LiDAR) data for leeward Kohala, Hawai’i Island identifies spatial and temporal patterning in regional agricultural development. Differential densities of alignments suggest variable levels of agricultural intensity. Agricultural processes of expansion, segmentation, and intensification can also be discriminated, with distinct zones of the field system having undergone different mixes of development. Areas within the field system with moderate to high levels of both average production and variability in production (determined using a climate-driven productivity model) were utilized relatively early in a highly intensified manner; these areas often underwent processes of segmentation and intensification. Less productive areas were developed later and exhibit evidence of expansion with lower amounts of segmentation and intensification, at set levels of intensity. The spatial and temporal variability in agricultural activities was influenced by the diverse environmental conditions across the landscape as well as variation in cultivars and cultivation techniques. Combining the high-resolution LiDAR data from a large area with potential productivity modeling allows for a more fine-grained understanding of agricultural development in this region of the Hawaiian archipelago.     

Transgender migrations: prostitution,identity and notions of ‘home’ in contemporary France

ABSTRACT

Migrant street prostitution in France has increased since the 1990s, largely as a result of the ease of movement facilitated by political shifts in Eastern Europe opening up national borders and the arrival of greater numbers of prostitutes from Africa and China. These often precarious migrations have generally been made by cisgender females; although, a comparatively smaller (but progressively significant) number are transgender. The representation of this latter group is explored in this article through four documentary/docufiction films that respectively recount what can be described as the sequential stages of geographical mobility (i.e. pre-migration, migration, and post-migration). Motivated by the concern that more particular voices within the ‘queer community’ are insufficiently represented, the focus here will be on how this group of transgender migrant prostitutes articulate a sense of ‘home’. Analysis is framed through Sara Ahmed’s notion of ‘home’ as ‘skin’, a porous space that blends the static and the mobile, the ‘here’ and ‘there’. The selected texts disarticulate the epistemology of prostitution in gendered terms and dislocate the transgender body from material associations that link successful migration with the movement from one place and body to another.     

Tropical African cultigens from Shongweni excavations,Natal

Plant material preserved in an arid cave at Shongweni, Natal, has been identified as the fruiting inflorescences of Eleusine coracana, Pennisetum typhoides and Sorghum bicolor. Pieces of outer wall of cucurbits have been identified as Citrullus lanatus and Lagenaria siceraria. All these are tropical cultivars exotic to the area. Radiocarbon dates from the relevant levels indicate that they date back to the third millennium BC. The implications of such an early date for the occurrence of these species as far south as Natal are discussed.
