Military might is widely recognized as having been a key element in the Mercian kings’ ability to forge and maintain a large kingdom in midland England in and after the seventh century. The paper argues that its basis was a network of fortified places – all major royal settlements that were given substantial defences in the eighth and early ninth centuries – and a systemic mechanism for manning them. The archaeological evidence of these defences at Hereford, Tamworth and Winchcombe is reviewed; the probable locations of other such early fortified places in midland England are considered; and the significance of this burghal system for our understanding of ‘the supremacy of the Mercian kings’ is weighed.  相似文献

A series of graves belonging to the Phoenician period were investigated after the campaign excavation of 2007 in the Phoenician‐Punic necropolis of Monte Sirai (Carbonia, Sardinia, Italy). One tomb in particular (labelled 252) is presented here because of its uniqueness. Tomb 252 contained the cremated remains of an individual, probably male, and comparison of the excavation records alongside reconstruction of the bone material itself makes clear that the individual was cremated in a prone position. It represents the first case of prone cremation reported in the literature. To investigate whether the temperature of the cremation was homogenous across the entire body, we have conducted a combined physical–chemical analysis using X‐ray diffraction spectroscopy and Fourier transform infrared.

Accessibility is now a common way to measure the benefits provided by transportation–land use systems. Despite its widespread use, few measurement options allow for the comparison of accessibility across multiple urban systems, and most do not adequately control for market competition between demand-side actors and supply-side facilities in localized markets. In this article, we develop a measure of competitive access to destinations that can be used to accurately compare accessibility between regions. This measure stems from spatial interaction modeling and accounts for competition at both the supply and demand sides of analysis, regional differences in transportation networks and travel behavior, and any imbalance between the size of the population and the number of opportunities. We use this method to compute access to employment for Canada's eight largest cities to comparatively examine inequalities in accessibility, both within and between cities, and by travel mode.  相似文献
