Radiocarbon dates for the late Middle Palaeolithic at Pech de l'Azé IV,France

This paper reports a series of radiocarbon dates on bone samples coming from the Mousterian of Acheulian Tradition (MTA) Layer 3 at the top of the Pech de l'Azé IV (Pech IV, France) Middle Palaeolithic sequence. All of these samples showed evidence of human impact, and they were prepared using current pre-treatment techniques to remove or identify contamination. The results indicate that the MTA at Pech IV started prior to the current limit of radiocarbon calibration (circa 50 ka BP) and ended by 45 ka cal. BP. These dates are supported by additional TL and ESR dates from the sequence, confirm previously suggested correlations between Pech I and IV, and generally fit within the known age range for the MTA. The oldest dates reported here may also lend support to still older TL dates for the MTA that taken together suggest that the MTA extended from late MIS 4 or early OIS 3 through to the end of the Middle Palaeolithic in southwest France.     

RUSSIAN RAILWAYS AND THE SEABORNE GRAIN EXPORT TRADE: 1883-1911

The interaction between railway development and agricultural expansion is a salient feature of the post-emancipation Russian economy. The railway network's growth allowed the Empire's agricultural core to shift southeastward and facilitated rapid growth in grain exports. Exports rose initially through the Baltic ports and later through the ports of the Black and Azov seas. A limited degree of regional specialization emerged, but governmental constraints and overall economic immaturity hampered further economic development.     

The relative effects of core surface morphology on flake shape and other attributes

It is long been thought that many flake attributes, including both size and shape, are largely due to the morphology of a core’s flaking surface, yet this has never been tested under strictly controlled conditions. Using molded glass cores with surface morphologies that highly resemble prehistoric ones, this experiment demonstrates that while core surface morphology does exhibit some influence on flake size and shape, a high degree of variation in flakes produced with the same core surface morphology shows that the effects of other independent variables, such as exterior platform angle and platform depth, have an even stronger effect. A major implication of these results is that current approaches to reconstruct prehistoric knapping strategies are overlooking significant sources of variation.     

Context, curation, and bias: an evaluation of the Middle Paleolithic collections of Combe-Grenal (France)

The site of Combe-Grenal is arguably the reference site for the Mousterian of southwest France. Bordes excavated the site over a period of 13 years and generated a large collection of lithics and fauna from a deep series of 64 Lower and Middle Paleolithic levels. Though Bordes only partially published his work at the site, its long stratigraphic sequence and particularly its collections have been subjected to numerous studies over the years and have figured prominently in several long-running debates concerning the Mousterian. Recently, the authors undertook a project to inventory and analyzed these collections along with the documentation of their archaeological context. In so doing, however, a number of serious problems became apparent with the collection in its current state, problems that cannot easily be resolved given the state of the available documentation. These problems have important implications not only for results of studies based on these collections, but more generally, they also point to problems in terms of how archaeological collections are curated.     

Out from the (Green) shadow? Neoliberal hegemony through the market logic of shared urban environmental governance

Recent work in critical geography describes the neoliberalization of urban social service provision through a transition from state provision to civil sector delivery. The concept of a ‘shadow state’ is deployed by some social theorists to describe this process by which nonprofits with government contracts increasingly adopt a state-oriented agenda for the execution of social entitlement programs. Possible linkages between the neoliberalization of urban environmental service provision and a shadow state are lacking by comparison. I, therefore, use qualitative data concerning three organizations in Milwaukee, Wisconsin to demonstrate that civil sector groups are stepping up as local government diminishes its markets for municipal environmental labor. However, the diverse compositions of these shared governances potentially complicate the efficacy of a shadow state thesis for describing environmental provision in inner-city Milwaukee. Instead, I argue that a Gramscian interpretation of shared governance better accounts for the neoliberalization of environmental service provision as government agencies and civil sector groups relate to one another through hegemonic market logic. I argue that this provides a more nuanced picture of how governance concerning the urban environment is constructed by the government, market, and civil sectors to further shape human social reproduction.
