Ballistically anomalous stone projectile points in Australia

The emergence of stone-tipped projectile weaponry was an important event in hominin evolution. A common archaeological approach to identifying projectile weapons is to extrapolate from optimal values of ballistically-relevant attributes as determined from ethnographic North American weapons and modern experiments. Among the most significant of these attributes is “tip cross-sectional area” (TCSA) because it determines a point's efficiency in penetrating an animal. The warranting argument for projecting these data onto prehistoric artefacts is that past “research and development” necessarily led to stone projectiles with optimal TCSA values for a given delivery system. However, our test of this warranting argument, involving analysis of 132 hafted ethnographic Australian stone projectile points and 102 hafted knives, demonstrates that Aborigines did not optimize TCSA values, thus offering a challenge to TCSA-based narratives about the first appearance of projectile weaponry. This illustrates the difficulty of inferring ancient stoneworkers' design intentions from narrowly-defined optimal values. Instead, tool designs should be considered in the context of the reduction sequences that produced them and the dynamics of transmission of those reduction sequences across generations.     

Palynological study of a Mi'kmaw shell midden,Northeast Nova Scotia,Canada

Before now, no palynological studies were made on shell midden deposits in Nova Scotia, despite a long history of archaeological research. A test study of samples taken from the shell midden at Maligomish (Indian Island) on the Northumberland Strait was conducted to determine if sufficient pollen, fern and moss spores, and other non-pollen palynomorphs (NPP's, including fungal remains, algal spores) could be recovered to allow interpretation of environmental conditions at the time of deposition. Several pollen processing methods were tested: sieving and swirling, chemical treatment with cold HCl, 5% KOH and brief exposure to 5% NH₄OH, and treatment with acetolysis solution. We recovered variable amounts of pollen, spores and NPP's from samples taken at 3–5 cm, 5–15 cm and 15–25 cm below surface. Abundant microcharcoal fragments prevented effective use of the swirling technique, but sufficient palynomorphs were recovered by chemical treatments to allow assessment of down-section changes in assemblages. Three radiocarbon ages from Mya arenaria and Crassostrea sp., and measurements of sediment grain size, moisture, organic and inorganic carbon, provide a framework for analysing palynological assemblage changes and context for interpreting differential palynomorph preservation. Despite some oxidation and microbial degradation of palynomorphs in the time interval (ca. 380–1600 cal yr BP), the midden assemblages correlate with pollen zones from marine and lake core sites within ca. 50 km of Maligomish. Shifts in abundances of algal spores, testate amoebae and aquatic plant pollen also indicate changes in depositional conditions during the time of midden use. The study provides the first reference for archaeologists attempting to use palynology for analysis of samples from Nova Scotian shell-bearing contexts.     

Traditional and computed tomographic (CT) techniques link modern and Cenozoic fruits of Pleiogynium (Anacardiaceae) from Australia

Computed tomography (CT) and traditional techniques were used to study the internal morphology of modern fruits of Pleiogynium timoriense (DC.) Leenh., and phosphatized and silicified fruits that were considered to belong to the genus. The results demonstrate that phosphatized fruits from the Oligocene–Miocene Dunsinane site at Riversleigh and silicified fruits from the Oligocene Glencoe Site, which are both in Queensland, are referable to Pleiogynium. The Riversleigh material (Pleiogynium wannanii Rozefelds, Dettmann & Clifford sp. nov.) is very similar to extant P. timoriense (DC.) Leenh. Both possess locules that, in the vertical axial plane, are asymmetrically reniform and enclosed by a two-layered endocarp, the inner layer woody and resistant to decay, the outer of fibres and parenchyma, surrounded by a mesocarp of fibres and sclereids and a parenchymatous exocarp. The outer mesocarp is sculpted by meridionally arranged, elongate depressions (germination apertures) situated at the dorsal surface of each locule; erosion of the mesocarp and outer endocarp provides passage for emergence of the embryo’s radicle on germination. The silicified material from Glencoe (P. parvum Rozefelds, Dettmann & Clifford sp. nov.) is smaller in all its parts and has locules that are ovate in the vertical axial plane. Discrete, cap-like, opercula are not evident in the fruit wall of the fossil and extant fruits studied. The presence of Pleiogynium, and associated taxa, indicates the existence of rainforest communities at Glencoe, and mixed open forest/rainforest at Riversleigh during Oligocene–Miocene times. The multilocular, fossil fruit described as Pleiogynium mitchellii Collinson, Manchester and Wilde from the Eocene deposits at Messel Quarry, Germany, is not considered to belong in the genus, as evidence of elongate depressions on the dorsal surface of the fruit stones has not been demonstrated conclusively, and its internal morphology/anatomy differs significantly from that of Pleiogynium.     

Regional Wage Rigidity: The European Union and United States Compared

In recent years it has been pointed out that regional unemployment disparities are much more entrenched across member states of the European Union (E.U.) than they are in the U.S. A 'conventional wisdom' has emerged to the effect that this difference is due in part to the greater degree of wage rigidity in E.U. regions. In this paper we explore this issue by estimating short run and long run real wage (in)flexibility for the regions in five core E.U. countries (Germany, France, Italy, the United Kingdom, and the Netherlands) and for the U.S. states for the period 1976–1994. We find that real wage (in)flexibility varies across regions both in the E.U. and the U.S., but that, on average, regional wages are no less flexible in E.U. core regions than in U.S. states. The paper also examines some of the possible correlates ofregional variations in wage (in)flexibility.     

Magdalenian Children: Projectile Points,Portable Art and Playthings

Children, no doubt, were a significant component of Upper Palaeolithic societies. Despite this fact, however, serious identification and consideration of material culture which may have belonged to children – at least at one time during their use‐life – have not been undertaken. This situation extends to the best represented and most intensively studied of the European Palaeolithic techno‐complexes, the Magdalenian (c.21,000–14,000 cal BP), and consequently, we know very little about the children of this enigmatic people. As play, including object play, is a ‘true cultural universal’, we can be certain that Magdalenian children integrated objects into their games, with these playthings later incorporated into the archaeological record. Through examining ethnographic accounts of recent hunter‐gatherer children and reconsidering archaeological assemblages in light of these data, this paper suggests that Magdalenian playthings probably included full‐sized adult weapon tips and – more significantly – pieces of what archaeologists term ‘art mobilier’.     

International competition,urban governance and planning projects: Malmö, Birmingham and Lille

In recent years competition between European cities has increased. This article looks at the implications for planning projects in the context of changes in urban governance. Growth machine and urban regime theories are introduced and three case studies explored in detail. Plans and development projects resulting from the arrival of the Oresund bridge in Malmö are examined. In Malmö, public planning is being bypassed in favour of local corporatist objectives and this experience is compared to the approaches developed in the strongly competitive cities of Birmingham and Lille. International comparison reveals the national distinctiveness of the responses to competition. In Birmingham there has been a local political reaction to the economic development‐led city centre strategy, but British central‐local relations restrict the ability of the city to change course. Developments in Lille reflect an integrated public sector approach to the development and marketing of the city and its region. In the three cases social and environmental issues have been raised but the imperatives of competition remain dominant.
