Experimental Systems in the Co-Construction of Scientific Knowledge**

The publication of Toward a History of Epistemic Things 25 years ago was a landmark in science studies. Not only was the book a brilliant overview of new research trends, but it was also a personal and highly original contribution because of its emphasis on the major role of experimental systems in the construction of scientific knowledge. The paths that it opened have not yet been fully explored. More seriously, the ambition of the author to reinforce the value of scientific knowledge by the role of experimental systems in its construction has not been pursued.     

Roman Rhine settlement dynamics evidenced by coin distribution in a fluvial environment (Oedenburg,Upper Rhine,France)

On the basis of archaeological and alluvial records, this paper presents the first spatial analysis of artefacts in relation to the evolution of the Rhine River, at the Gallo-Roman site of Oedenburg, during the first four centuries AD. The dataset consisted of several thousand Roman artefacts found by pedestrian prospecting over the last twenty years, over half of which were coins. This dataset was used together with high-resolution topography and geomagnetic mapping, to reconstruct settlement evolution, both on the terrace and in the floodplain. A comprehensive monetary chart has been compiled for the Oedenburg site, which highlights four major phases of settlement. These results provide a possible causal link connecting historical factors and alluvial events with intra-site evolution. Therefore, while changes observed during Phases I (until AD 68), II (AD 69 to AD 180) and III (AD 180 to AD 295) seem largely related to historical and societal events, Phase IV (AD 295 to AD 402) shows patterns of abandonment of the lower part of the floodplain that may well be related to an unusually humid period in the fourth century. These results are set in a broader context, from the Rhine catchment area to the Alps, and are in agreement with the wet conditions also documented in alluvial, lacustrine, geomorphological and palynological records in Germany (Lahn River, Lake Constance, Lake Nussbaumen, Kaisersthul area and the Black Forest). Studying the intra-site spatial distribution of artefacts with high temporal constraints, at a long-lived site with contrasted topography, opens new avenues for the detection of discreet events such as a higher water table, affecting only the lower zone.     

The Softwood Lumber Dispute and US Allegations of Improper NAFTA Panel Review

The dispute over Canadian exports of softwood lumber products to the United States (US) has lasted since 1982 and, so far, has gone through four episodes of litigation. In Lumber IV, the US International Trade Commission (ITC) determined that the US softwood lumber industry was threatened with material injury by reason of dumped and subsidized lumber from Canada. Under the North American Free Trade Agreement (NAFTA), a binational panel concluded, however, that there was no such evidence and directed the ITC to reverse its finding. In its resort to the Extraordinary Challenge Procedure, the US alleged that the injury panel had misapplied the US standard of review. In fact, allegations of improper NAFTA panel review were used by the US in order to justify its non-compliance with adverse binding decisions.     

Palaeogeographical reconstructions of Lake Maliq (Korça Basin,Albania) between 14,000 BP and 2000 BP

Since the early 1990s, excavations of a protohistoric lakeside settlement in the Korça basin carried out by a French–Albanian archaeological team have induced geomorphological and palynological studies about the sedimentary records of Lake Maliq. These studies allow us to distinguish a series of centennial-scale high and low lake level events between 4200 and 4000 cal BP (2899–2637 BC/2843–2416 BC) and 2600 cal BP (822–671 BC), probably due to large-scale climate changes (in the Mediterranean basin). In addition, the sediment sequence also gives evidence of a millennial-scale trend of lake level rise. It appears to be an interplay between lake level rises and falls against tectonic subsidence of the basin allowing accommodation space for sediment deposition.The variations of the lake's level and the lake's surface area influenced the development and the abandonment of the nearby lakeside settlements (like the tell of Sovjan). In order to prepare an archaeological survey around the now dried up lake, we made a 3D model of the Holocene deposit from the lake including these lake level results, geomorphological mapping, excavation data, numerous core logs, AMS ¹⁴C dating and SRTM DEM data. The GIS model allowed us to propose four palaeogeographical reconstructions of the extension of Lake Maliq: around 14,000 BP, during the Mesolithic (around 9000 BP – 8781–8542 BC), the Early/Middle Bronze Age transition (around 3800 BP – 2310–2042 BC) and the Iron Age (2600 BP – 822–671 BC). A map of the thickness of the sediments above potential archaeological layers is also proposed.     

SEEING SPATIAL STRUCTURES: ON THE ROLE OF VISUAL MATERIAL IN THE MAKING OF THE EARLY QUANTITATIVE REVOLUTION IN GEOGRAPHY

This article examines the role that visual material played in the early years of the quantitative revolution in Anglophone geography. It is part of a larger project that attempts to write a history of geography's scopic regimes in the twentieth century and draws on post‐positivist approaches to the history of science. It is argued that there are a number of strategic as well as theoretical reasons for such a reliance on images in the quantitative revolution. Some reasons are unique to the quantitative revolution in geography, some resemble a more general way in which paradigm shifts take place in science and some are located outside of academia. This article is primarily interested in the internal view on the geography of the quantitative revolution and its rationalities. The paper departs from Christaller's hexagon, as one of the most influential and iconic. It then broadens the view to include a much wider range of visual material, arguing for some more general observations on the use of images in geography during the early quantitative revolution. It is argued that there was a significant shift of forms and functions of visual material. Overall, it is argued, visual material gained in importance and while geography was getting “thinner” and more abstract, its role in making visual arguments became stronger. From being merely an aid for seeing, visual material became a prime carrier of knowledge.     

Public archaeology at Baynard-Zion: bringing life back to an antebellum cemetery

ABSTRACT

Heritage tourism is a driving economic force in much of the coastal southeastern United States, including on Hilton Head Island, South Carolina, one of the most popular destinations for vacationers in the country. Working with local community members in developing a diverse and multipronged public archaeology program, we helped facilitate research and develop programing at the Baynard Mausoleum and Zion Chapel of Ease and Cemetery (Baynard-Zion). Built and used during the late eighteenth through mid-nineteenth centuries, Baynard-Zion includes some of the oldest marked graves on the island as well as its oldest standing architecture. Using a constellation of techniques, including geophysical surveys, genetic testing of human remains, and limited excavations, research conducted at Baynard-Zion provides an opportunity to enhance public perception and understanding of pivotal historic events and people on the island while also assisting in development plans that promote heritage tourism.
