On the accuracy of estimating living stature from skeletal length in the grave and by linear regression

This study evaluates a method for obtaining stature estimates for populations represented by skeletal material, with individuals buried in a supine position. During the excavation of a Danish mediaeval cemetery, in situ skeletal length in the grave was measured from a point above the cranial point farthest from the body to the most distal point of the talus. The measurement was made with a folding rule placed on the sagittal midline of the skeleton, allowed to follow any curvature of the skeleton in situ. In the laboratory, stature was reconstructed anatomically, and this stature was regarded as an accurate estimate of living stature. Stature was also reconstructed from femur length by two linear regression procedures: 1) by sample and sex specific formulae, employing a leave‐one‐out approach, and 2) by sex wise formulae for Euro‐Americans from Trotter & Gleser (1952, American Journal of Physical Anthropology 10 : 463–514). Skeletal length in the grave and the two stature estimates based on linear regression were compared to anatomically reconstructed stature. Skeletal length in the grave estimated anatomically reconstructed stature with practically no bias (95% CI: −1.3–1.5 cm). Sample specific regression formulae estimated anatomically reconstructed stature also with no bias (95% CI: −1.2–1.1 cm). In contrast, statures calculated from Trotter & Gleser's regression formulae estimated anatomically reconstructed stature with a bias of about 4 cm (95% CI: 3.3–5.0 cm). Estimates of stature variance were biased for all three estimation procedures. However, for samples of adults, an adjusted variance estimate can be obtained by subtracting 8.7 cm² from the variance obtained from skeletal lengths in the grave. It is recommended to measure skeletal length in the grave whenever possible, and use this measurement for estimating statures for prehistoric and early historic populations.

Competing discourses of territorial development: tensions between cities and regions as a result of the new regionalism

Competition between metropolitan areas and old regions is one of the most visible results of the ‘new regionalism’ policy in the EU. The aim of this paper is to explain the newly emerged tensions between the regions and the cities within the EU in the context of the ‘new regionalism’. The newly introduced ‘Integrated Territorial Investments’ (ITI), a potentially powerful instrument of the cohesion policy of the EU was presented as ‘a flexible mechanism for formulating integrated responses to diverse territorial needs’. However, this flexibility produced a competitive relationship between cities and regions in their chase for money. Based on interviews with sub-state officials, the study focuses on two countries: Czechia and Slovakia. They are both major recipients of EU structural funds and the ITI tool is being implemented in both of them, however with different outcomes. Three variables have been identified as major factors causing the tensions: insufficient administrative capacity, political challenges and lack of shared understanding of priorities of regional development among sub-state actors.     

Neoliberalising the divided city

This paper examines the relation between ethno-nationalism and neoliberalism in urban space. Contrary to common views in urban studies, it argues that the ‘ethno-nationally divided city’ and the ‘neoliberal city’ are not antithetical, but that neoliberal nationalism is a new modality of urban conflict in a globalised world, which reshapes the relation between the local and the global and draws new urban geopolitics. By investigating practices of nation-branding in a divided city, this paper bridges different theoretical fields to shed light on an aspect of urban conflict that has largely been ignored by the literature on nationalism and urban divisions. It also complements existing research on neoliberal nationalism by emphasising the spatial and material aspects of nation-branding, and by showing how it can be used by competing ethno-national leaders to mobilise their communities and extend their control at the national and urban levels. By highlighting processes common to neoliberal and divided cities, this paper draws on recent calls within urban geopolitics to rethink current theoretical categories and labels attributed to cities. It develops this analysis by examining contemporary neoliberal urban policies in Skopje, Macedonia, which have become a new battlefield where interethnic conflicts unfold.

The Preservation and Identification of Piñon Resins by GC‐MS in Pottery from the Western Great Basin

Gas chromatography — mass spectrometry analysis of a sherd from the Nevada Test Site revealed a high quantity of terpenes, including sesquiterpenoids and diterpenoids, demonstrating that piñon resins were prepared in the pot in prehistoric times. The presence of these biomarkers allowed for a very specific identification of the products prepared in the pot, a level of detail not often achieved in lipid residue analysis. That the terpenes are relatively unoxidized demonstrates that they are quite stable over long periods of time. The study also shows that sherds on the surface of archaeological sites can preserve lipids and terpenes and are amenable to organic residue analysis.     

On the similarity of tree‐ring patterns: Assessing the influence of semi‐synchronous growth changes on the Gleichläufigkeitskoeffizient for big tree‐ring data sets

The Gleichläufigkeitskoeffizient (GLK), or the percentage of parallel variation (%PV), is an often used non‐parametric similarity measure in dendrochronological research. However, when analysing big data sets using the GLK, this measure has some issues. The main problem is that it includes not only synchronous but also semi‐synchronous growth changes. These are years in which the growth in one of the compared series does not change in two subsequent years. This influences the GLK, often only slightly, but the larger the data set the stronger the effect. The similarity between tree‐ring series can be more objectively expressed by replacing the GLK with the synchronous (SGC) and semi‐synchronous growth changes (SSGC). The calculation is similar, since GLK = SGC + SSGC/2. Large values of the SSGC are indicative of possible anomalies or even errors. The SGC is much better suited than the GLK to describe similarity. The SGC should therefore be used to analyse big data sets, for clustering and/or dendroprovenance studies. It is recommended to combine the SGC with parametric measures.

Persistence of birefringence and specific collagen cross-links in dentine of teeth of the ‘Nuraghi’ population living in Sardinia BC 1500–1200

Well preserved bones of the Nuraghi population, discovered in 1980, are deposited in the Department of Biomedical Sciences, Division of Human Anatomy of the University of Sassari, in Sardinia, Italy. The Giant Tomb belongs to the megalithic monuments constructed in the period BC 1500–1200. The origin, history and the fate of Nuraghi population is not well known. Many cone-shaped fortresses are found in Sicily and megalithic monuments for burial purposes were built in their proximity. Due to the good macroscopic preservation of the mineralized parts of the Nuraghi skeletons we decided to compare the histological and biochemical structure of the recovered Nuraghi teeth with contemporary ones. Crown dentine of four Nuraghi molar and four premolar teeth were analysed and compared with contemporary molars and premolars removed for orthodontic reasons from 17–40-year-old patients in the Dental School, University of North Carolina at Chapel Hill USA. Evaluation of the collagen cross-links of dentine collagen was performed using a HPLC technique to analyze for hydrolysates. Nonreducible, stable cross-links pyridinoline and its lysyl analogue were quantified by fluorescence (excitation 330 nm, emission 390 nm). The concentration of reducible, labile cross-links referred to as DHLNL and HLNL (dehydro-dihydroxylisinorleucine) were identified and calculated by chromatography after the application of NaB³H₄ with integration of respective peaks and converting the numbers into a residue per mole of collagen basis. The ultrastructure of collagen was estimated by its persistent birefringence in polarized light after staining with Picrosirus Red. It was found that dentine collagen of Nuraghi teeth resisted environmental factors sufficiently well to preserve the molecular ultrastructure of collagen fibres, proved by their birefringence and by the preservation of some of the stable and reducible collagen cross-links, characteristic for skeletal tissues. © 1998 John Wiley & Sons, Ltd.     

At the Transition from Late Medieval to Early Modern: the Archaeology of Three Wrecks from Turkey

During surveys in the Rhodian Straits in 2005–06, the staff of the RPM Nautical Foundation discovered three deepwater wrecks which reflect elements of the transition from late medieval to early modern seafaring. The assemblages, and their plotting on site‐plans generated from photographic evidence, point to the finding of a small oared warship equipped with wrought‐iron carriage‐ and swivel‐guns, a small coasting vessel armed with wrought‐iron swivel‐guns, and a larger merchantman equipped with cast‐iron carriage‐guns. While the features of the smaller vessels do not identify their country of origin, those of the larger merchantman have good parallels with known English wrecks. © 2009 The Authors
