ABSTRACT

Outdoor play is considered an essential aspect of a ‘proper childhood’. However, unsupervised outside play is declining, a decline attributed to parental anxieties about children’s safety. However what drives these anxieties and how this impacts on contemporary outdoor play is less clear. Our paper seeks to explore this through an analysis of adult narratives generated through digital map-making and forum discussion about where they played as children and where they would allow a child to play unsupervised now. Our analysis explores the nature of these narratives and pivotal moments in which adults articulated the disconnect between their own recollections of idyllic spatial freedom and the spatial restrictions they place on contemporary children. This offers a rich understanding of how parents navigate conflicting cultural imperatives on risk-avoidance and children’s rights to a ‘good’ childhood.  相似文献

SUMMARY

The Victoria Cross, Britain’s highest award for gallantry in the face of the enemy, is commonly believed to be cast from the bronze of Russian cannon captured at Sebastopol during the Crimean War. There is no corroboration for this belief beyond an entry in The Times in 1857. Historical sources suggest that neither the Queen nor her Prime Minister would have favoured an association of the medal with Sebastopol. From 1914, however, it is likely that many Victoria Crosses were indeed sourced from captured ordnance, but probably using Chinese guns. Some may even have been cast from entirely unprovenanced metal. Recent examination of VCs and putative sources of their metal by X-ray fluorescence suggest multiple sources of material, presenting medals variously of bronze, brass and copper.  相似文献

This journal published the first reported identification of Mycobacterium tuberculosis complex (MTB) DNA in ancient human remains but concerns were raised about the article two years after publication. These were based on methodology which, in the field of ancient DNA, was still developing. Here we present a re‐examination of the 1993 research conducted on three specimens which exhibited palaeopathologies indicative of tuberculosis. The specimens were: an ulna from pre‐European‐contact Borneo, a spine from Byzantine Turkey, and a lumbar‐sacral spine from 17th century Scotland. There was insufficient material to permit re‐examination of all of the original samples. The earlier results were confirmed in two independent laboratories using different methodologies. MTB DNA complex‐specific DNA amplicons were obtained, and sequenced in both laboratories, in a re‐analysis of samples which supported the earlier findings.
