Palynology, radiocarbon dating, and open-section stratigraphies from archaeological trenches are used to examine the impact of human activity around the time of Norse landnám on vegetation and landscape associated with a small farm (Ø34) in the Qorlortoq valley, Eastern Settlement, Greenland (61° N 45° W). Peat deposits from a mire abutting the Norse ruins revealed a discontinuous palaeoenvironmental record containing a possible hiatus from ca. AD 410–1020. Palaeovegetational data were recovered either side of this period. Pollen assemblages suggest that open Salix scrub dominated the landscape during the pre-settlement phase. The later phases of landnám resulted in the creation of hay fields and heavily-grazed grassy heath. Site abandonment is reflected by a re-expansion of Salix. This occurs shortly before the onset of deposition of a Sphagnum peat, dated to cal AD 1420–1630 (2σ) and reflecting an increase in mire surface wetness, probably in response to a deteriorating climate. Radiocarbon dates were obtained on peat and plant macrofossils sampled from either side of the proposed hiatus at two different but closely-spaced (<20 m) locations across the mire. These produced significantly different dates for the cessation of peat formation in the pre-landnám period (cal BC 2130–1770 and cal AD 240–410 respectively), but near-synchronous dates for the recommencement of peat growth (cal AD 890–1150 for peat and a probably more reliable interval of cal AD 1020–1190 based on plant macrofossils). It is suggested that this hiatus may represent the first direct evidence for peat cutting in Norse Greenland. 相似文献

The South African War that broke out in October 1899 was bothvery old and very new. It was a traditional war, the last ofthe old-fashioned British imperial wars, with cavalry playinga significant part. But it was also a very modern war, for instancein the British Army's use of railways to subdue the Boers inthe early months of 1900, or the use of trench warfare by theBoers along the Modder river. It was disturbingly new in theway that it changed in the autumn of 1900 from a war betweenarmies to a guerrilla war against a civilian population, mostdistastefully so in the British concentration camps set up tohouse Boer women and children. Above all, it was a distinctlycontemporary war in its impact on the media, especially thenewspapers, and in the interaction between the media and thoseparticipating in the fighting. It was a significant war, farbigger than originally expected, and was therefore big news.The British Army, ill-prepared for the original Boer invasionof Natal, at first numbered 75,000 troops. In the end, the Britishand imperial forces totalled 450,000 with contingents from Canada,Australia, New Zealand, and India. The British lost 22,000 men,13,000 of them from disease. The Boers lost about 7,000 in thefield, while another 27,000 (many of them very young children)are estimated to have died in the concentration camps. Therewere also about 20,000 black and coloured Africanswho died in concentration camps, though this was little reportedat the time. So it was a major episode in British military history.The impact on British opinion of the relief of Ladysmith andespecially of Mafeking in 1900 was quite overwhelming. In afrenzy of jingo celebration, the verb maffickingentered the language. In these circumstances, the consequencesof the Boer War on the media and its representation of war wereinevitably massive. 相似文献

Spaces of Utopia and Dystopia: Landscaping the Contemporary City 总被引:2,自引:0,他引:2
Some of the most recent literature within urban studies gives the distinct impression that the contemporary city now constitutes an intensely uneven patchwork of utopian and dystopian spaces that are, to all intents and purposes, physically proximate but institutionally estranged. For instance, so–called edge cities (Garreau, 1991) have been heralded as a new Eden for the information age. Meanwhile tenderly manicured urban villages, gated estates and fashionably gentrified inner–city enclaves are all being furiously marketed as idyllic landscapes to ensure a variety of lifestyle fantasies. Such lifestyles are offered additional expression beyond the home, as renaissance sites in many downtowns afford city stakeholders the pleasurable freedoms one might ordinarily associate with urban civic life. None–the–less, strict assurances are given about how these privatized domiciliary and commercialized 'public' spaces are suitably excluded from the real and imagined threats of another fiercely hostile, dystopian environment 'out there'. This is captured in a number of (largely US) perspectives which warn of a 'fortified' or 'revanchist' urban landscape, characterized by mounting social and political unrest and pockmarked with marginal interstices: derelict industrial sites, concentrated hyperghettos, and peripheral shanty towns where the poor and the homeless are increasingly shunted. Our paper offers a review of some key debates in urban geography, planning and urban politics in order to examine this patchwork–quilt urbanism, In doing so, it seeks to uncover some of the key processes through which contemporary urban landscapes of utopia and dystopia come to exist in the way they do. 相似文献
