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.     

Reform in the Canadian Parliament and the US Congress: Institutional Choices and Member Power

A spate of recent work on the Canadian Parliament highlights the importance of constituency pressures in understanding the legislative behavior of individual Members of Parliament (MPs). In light of this renaissance, we reexamine decisions by Canadian Liberal Party MPs to defy Prime Minister Jean Chrétien and his cabinet by supporting party-weakening reform in 2002. More specifically, we model votes on the question of selecting committee chairs through secret ballot as a function of factors both internal and external to the Parliament. While we find some evidence of exogenous, constituency-based forces, we find that support for reform was largely driven by internal party power dynamics. We gain additional insight into our findings by comparing this reform to analogous reforms in the US Congress. The patterns we uncover highlight the stark difference between the “double monopoly of power” held by party leaders in Westminster-style legislatures and the lack of such a monopoly in Congress. We conclude by advocating for more such comparisons, arguing that careful efforts to synthesize these and other similar reforms can improve our understanding of both legislatures despite the obvious and important differences between them.     

A Neolithic innovation in eastern Arabia: haematite axes and adzes

Well before metallurgy, Neolithic societies in the Gulf were engaging in a very peculiar form of metal object production, particularly of axes and adzes made from haematite. In the heart of the Neolithic Middle East, this innovation was specific to Arabian shores between the Musandam and Qatar peninsulas. Quite infrequent among Neolithic lithic assemblages from Arabia, axes and adzes were mostly collected on the surface of domestic settlements. One is often dealing with objects to which the most focus has been given, apart from arrowheads and projectile points. Several sites or outcrops are present on the Emirati coastline and Gulf islands. Inland mountain ranges also include some of these. From Ra’s al-Khaimah to Qatar, only 500 km separate the most distant Neolithic domestic settlements which possess haematite axes or hoes, a distance that is quite small when one considers the circulation of polished stone blades in other societies of the same period. Within the Middle East, south-eastern Arabia during the Neolithic engaged in a very original means of production of metal objects, as the latter did not focus on copper, a very malleable and much more available material, but on haematite, which was much harder.     

Ceramic Traditions and Cultural Identities: West‐Central France during the Late Neolithic II Period (c.3400–2900 cal. BC)

Pottery is generally used as the main basis for characterizing Neolithic cultural identities: archaeologists tend to define groups and cultures in time and space on the basis of typological classification. This paper proposes a different approach to the study of pottery that takes into account the various steps of the chaîne opératoire of manufacture, particularly the methods used to form and finish the pots, in order to characterize the cultural landscape of the Late Neolithic II period in west‐central France (3400?2900 BC). This cultural landscape has hitherto been poorly defined and subject to endless debate since the 1950s, largely because the pottery is fairly homogeneous in shape and is mostly undecorated. The technological study presented here, based on the examination of 23 ceramic assemblages and focusing on a variety of stages in the chaîne opératoire, has allowed the definition of three technical traditions. The main characteristics and diagnostic features of these traditions are outlined below, together with their interrelationships.
