Maritime Archaeology in Uruguay: Towards a Manifesto

We report a collaborative maritime archaeological project in Uruguay, one of several Latin American countries where the subject is undergoing review in terms of the ways it is practised and managed. Uruguay is typical of many states where there has been a tension between a heritage-based approach in which the results of investigations are viewed as publicly owned, as opposed to the profit motive in which commercial and personal gain is the underlying ethic. This project was conceived both as a way of assisting the Uruguayan Heritage Commission in promoting the former approach as well as advancing a programme of research into the age of global exploration. This paper sets out the rationale of the initial field season and reflects on subsequent developments.     

Shifting Winds: Explaining Variation in State Policies to Promote Small‐Scale Wind Energy

States have increasingly taken leading roles in U.S. environmental policymaking over the past two decades. As laboratories of democracy, states have developed different levels and mixes of policies to address climate change, nonpoint source pollution, alternative energy, and other challenging environmental issues. Policy scholars have sought to explain variation in state environmental policy through two primary theoretical lenses: internal determinants and regional diffusion. While our understanding of state environmental policy adoption has grown to identify which variables are most important, less is known about how these variables interact in particular states to influence policy adoption. This study examines the interactions of variables from both theories to explain how state policies for small‐scale wind energy promotion were adopted in three U.S. states. Our results highlight the nuanced role of citizen ideology, which may be important in contexts at either end of the ideological spectrum but less important in the middle—where economic development is more critical. Results also indicate that interstate competition may be over environmental as well as economic leadership. Interestingly, strength of the wind resource is not necessarily correlated with policy adoption for small‐scale wind energy promotion.     

Re-placing plainware: Production and distribution of domestic pottery,and the narration of the pre-colonial past in the Peruvian Andes

The location of domestic pottery production is central to archaeological narratives. Yet too often, unfounded assumptions are made about place of production, especially in relation to place(s) of distribution and use. Only rarely is this geography of production and distribution explored in detail and with perspective. Here, we investigate this problem in the context of the Peruvian Andes. We present the results of extensive ethnoarchaeological research on the manufacture of domestic vessels in over thirty villages with potters in Northern Peru. Drawing on the ethnographic concept of technical style, we identify three tendencies on the relationships between toolkits, manufacturing techniques, geographic units, and exchange. From these tendencies we develop two models of domestic pottery production and distribution: the local production model and the non-local production model, which are applied in analysis of archaeological materials. While this distinction is apparently simple, we demonstrate how the explicit or implicit use of each of these models has shaped some of the most important debates and issues in Andean archaeology. In sum, we explain how understandings of the manufacture, exchange, and use of plainware impacts narratives about the pre-colonial past.     

Characterisation of obsidian subsource variability at El Paredón,Mexico

Portable X-ray fluorescence (pXRF) geochemical analysis on obsidian from five Formative period (1200 BCE to AC 100) sites from Tlaxcala, Mexico, has revealed that most of the material had similar values to those found in the closest obsidian source, named El Paredón, Puebla. Nevertheless, initial analyses did not resolve whether these materials came from the same caldera or from a specific obsidian deposit. Here we present a methodology that allows the identification of obsidian subsources. The results reveal that Tlaxcalan populations took advantage of a specific obsidian deposit called Tres Cabezas, Puebla, providing valuable new data to identify associated regional exchange networks.     

Standing at the gates of Europe: Human behavior and biogeography in the Southern Carpathians during the Late Pleistocene

This study presents a behavioral analysis of Middle and Upper Paleolithic lithic assemblages from 14 sites located in the southern Carpathian Mountains. Using a whole assemblage behavioral indicator, we show that the hominins that manufactured those stone tools do not appear to have differed in terms of the flexibility of the mobility strategies they employed to exploit their landscapes. Rather than biological change, we argue that large-scale climate changes are likely more important drivers of behavioral changes during the Late Pleistocene of the region, including during the Middle–Upper Paleolithic transition. These results agree well with the results of studies having employed this methodology in other regions, suggesting that this is a generalized feature of the transition across Eurasia. Recasting the transition as a mainly ecological rather than purely biocultural process allows us to generate new perspectives from which to approach the question of behavioral change during the Late Pleistocene, and ultimately suggests that the process referred to as the ‘Middle–Upper Paleolithic transition’ is essentially a brief segment of a much more extensive process driven by prehistoric human–environment interactions that would culminate in the highly logistical mobility strategies documented throughout the continent at the Last Glacial Maximum.
