Empirical aspects of the movement of strontium through the food chain suggest that the level of bone strontium can be used as an indicator of the percentage of meat in human diet. In general, skeletal remains from agricultural peoples are expected to have high bone strontium levels relative to hunter-gatherers from the same geographical region because plants contain relatively higher amounts of strontium when compared with animal products. The results of the study described in this paper, however, indicate that the inclusion of molluscs as a component of the diet may produce the opposite of the expected strontium values. Burials from an Archaic (c. 2500 BC) hunting-gathering population excavated from Luo25, an archaeological site in northern Alabama, USA, exhibit a mean bone strontium level (
atomic absorption;
neutron activation) that is higher than the mean level from an agricultural Mississippian (c. AD 1400) population (
atomic absorption;
neutron activation) that was buried at the same site. The samples were analysed by two techniques (atomic absorption spectrometry and neutron activation analysis) and the results compared favourably; therefore, the results can be accepted as valid rather than being due to technique error. We propose that the ingestion of molluscs, whose meat is known to contain large amounts of strontium, has produced this reversal from expected results. 相似文献

This article discusses the financial policies of the Papal States from the late eighteenth to the mid-nineteenth century in relation to the rest of Europe, and especially Italy. Its crucial starting point is the Napoleonic economic reforms, which had important and often lasting effects throughout its former empire. French reliance on debt reduction and heavy though equitable taxation improved the financial conditions of most European lands even as they convulsed from the protracted wars. The economic austerity prior to 1814 forced post-Napoleonic Europe to make decisions on the degree of continuity on these two financial fronts. Political instability beginning in the 1820s for some, and the early 1830s and late 1840s for the rest, upset the rather tenuous financial position that most lands found themselves in. For the Papal States, the Napoleonic period improved its financial position to the detriment of ecclesiastical institutions. The period also revealed the inherent flaws in its financial system, necessitating a decentralized approach to the restoration, relying on individual (or institutional) initiatives and large foreign loans, in lieu of overarching policies. By the 1850s, a further lack of financial control induced the renewal of Peter’s Pence. 相似文献

The child-friendly city advocates for children's ‘right to the city’. Much of this advocacy focuses on the independent child, with little attention paid to the accompanied experiences of younger children, such as those travelling in prams. This paper draws on a material feminist perspective to help address this gap. We offer the concept of mother–child–pram assemblage to bring to the fore the corporeal dimensions of everyday pram journeys. By analysing sensory ethnographic materials collected with mothers and young children living in Wollongong, Australia, this paper highlights how the ‘affective affordances’ and ‘affective atmospheres’ of pram mobilities shape urban experience by reference to how motherhood and childhood are achieved on-the-move. We conclude with policy-relevant insights for the child-friendly city. 相似文献

In Australia, e-government is continuously re-defining service boundaries. While this may be good in the case of transactional interactions, for example the online submission of tax returns, it is less clear that interpersonal services, such as working closely with the long-term unemployed, are best delivered digitally. We consider the impact of social services digitisation on vulnerable communities drawing on an analysis of remote Aboriginal communities. Digital uptake affords great opportunities, but it also carries risks. Some communities have no digital infrastructure and in certain cases traditional face-to-face services have been curtailed, leaving those not online with reduced assistance. We find that concerns about the ‘digital divide’ are well founded. Problems generated by e-government flow across boundaries and appear left to the third sector to resolve with the state playing an even more diminished role in the lives of disadvantaged citizens. 相似文献
