We compared independent mobility (freedom to move around the neighbourhood – or similar – without adult accompaniment) among English and Australian schoolchildren. Parents reported mobility licences granted to their children (e.g. allowing them to cross main roads alone) and accompaniment on local trips. Children reported travel mode to school. We examined associations between mobility licences and independent school journeys, and accompaniment on local trips. Among 10–12-year-olds, English children had more licences than Australian children. Mobility licences were directly associated with independent school journeys among primary but not among secondary schoolchildren who travelled further; and inversely associated with parental accompaniment to other destinations. Influences on parental restrictions should be examined to promote children's independent mobility.  相似文献

Consilience of genetics and archaeobotany in the entangled history of rice   总被引:3,自引:0,他引:3  
Major leaps forward in understanding rice both in genetics and archaeology have taken place in the past decade or so—with the publication of full draft genomes for indica and japonica rice, on the one hand, and with the spread of systematic flotation and increased recovery of archaeological spikelet bases and other rice remains on early sites in China, India and Southeast Asia. This paper will sketch a framework that coherently integrates the evidence from these burgeoning fields. This framework implies a reticulate framework in the phylogeny of early cultivated rice, with multiple starts of cultivation (two is perhaps not enough) but with the key consolidations of adaptations that must have been spread through hybridisation and therefore long-distance cultural contacts. Archaeobotanical evidence allows us to document the gradual evolutionary process of domestication through rice spikelet bases and grain size change. Separate trends in grain size change can be identified in India and China. The earliest centre of rice domestication was in the Yangtze basin of China, but a largely separate trajectory into rice cultivation can be traced in the Ganges plains of India. Intriguingly, contact-induced hybridisation is indicated for the early development of indica in northern India, ca. 2000 BC. An updated synthesis of the interwoven patterns of the spread of various rice varieties throughout Asia and to Madagascar can be suggested in which rice reached most of its historical range of important cultivation by the Iron Age.  相似文献

This article offers a comparative analysis of the origins and development of autonomism in interwar Alsace and the Moselle. Upon the liberation of the provinces in November 1918, the local populations of Alsace and the Moselle enthusiastically welcomed French troops. For President Raymond Poincare´ this enthusiasm constituted a clear ‘plebiscite’. But, in light of perceived heavy-handedness on the part of the new French rulers, this enthusiasm proved short-lived and rapidly gave way to a widespread malaise. In response to local fears for the preservation of their distinctive social, linguistic and religious traditions, Autonomist organisations emerged to oppose the loss of what they perceived to be the soul and character of Alsace and the Moselle. They rapidly became a pervasive force in local politics, cutting across ideological and class barriers and dividing parties. For the French government, autonomism represented a serious threat to national unity. For local autonomists, however, it represented an attempt to preserve local socio-economic structures and linguistic and cultural practices. The discussion here seeks to reposition autonomism within the context of local politics and to compare the distinct experiences of Alsace and the Moselle in the decade after their return to French rule.  相似文献

The waterways of London are an essential component of the city, with the River Thames playing a prominent role in the heritage, history and identity of place. The upcoming 2012 Olympics are highlighting the Lea Valley waterways in east London as another important part of London’s waterscape, expanding London’s global presence as a ‘water city’. As part of the Creative Campus Initiative, we undertook a project based on the broad themes of water, London and the Olympics that would give voice to the changes taking place. The result is London’s Olympic Waterscape, a 20-minute film comprising both ‘expert’ interview material discussing broad themes and developments and an embodied record of our engagement with the Olympic area during a brief period in the construction process. The present article is about the journey we took through and around the east London ‘Olympic’ waterways as we attempted to capture this transitional moment on video.  相似文献

The passing of the Aliens Act of 1905 was a defining moment in British immigration law and history. This article investigates the influence of settler-colonial immigration restriction laws on the passing of the Act, and questions the current historiographical inclination to focus solely on the influence of American immigration restriction laws. By analysing the trajectory of contemporary public debates, the evidence given to the Royal Commission on Alien Immigration (1902–03) and the political discussion on various bills, the article shows that the existence of colonial immigration restriction laws played an important role in the formulation and passing of the 1905 Aliens Act. Putting the Act in this larger context highlights its colonial derivation, but also its uniqueness: the British Act's defence of asylum, the exception extended to those landing as political and religious refugees, has no parallel in either early US law or any of the settler-colonial laws.  相似文献
