Critical Masses is a multidisciplinary pilot project that aims to graphically represent and mediate the histories, spaces and narratives concerning former nuclear installations within central Australia. These include the abandoned British atomic test sites at Emu Field and Maralinga, the Intercontinental Ballistic Missile (ICBM)/Intermediate Range Ballistic Missile (IRBM) rocket launchers at Woomera, and the decommissioned US National Security Agency early warning satellite base at Nurrungar. Significantly, each of these Cold War sites are situated in either hazardous, remote, secure and/or culturally sensitive areas and require sophisticated analysis and negotiation in order to best render their complexity for both online access and on-site tourism. In association with the Maralinga-Pilling Trust and traditional indigenous landowners a multi-tiered approach (re)creating these locations is being modelled across platforms for diverse audiences. Digital materials are being authored and designed for stand-alone DVD, online interactive sites and archives, an immersive/simulated space for interpretation centres, and augmented/enhanced reality interfaces via GPS and mobile/handheld devices used in situ at key sites. 相似文献

A major aim of including the spatial component in ecological studies is to characterize the nature and intensity of spatial relationships between organisms and their environment. The growing awareness by ecologists of the importance of including spatial structure in ecological studies (for hypothesis development, experimental design, statistical analyses, and spatial modeling) is beneficial because it promotes more effective research. Unfortunately, as more researchers perform spatial analysis, some misconceptions about the virtues of spatial statistics have been carried through the process and years. Some of these statistical concepts and challenges were already presented by Cliff and Ord in 1969. Here, we classify the most common misconceptions about spatial autocorrelation into three categories of challenges: (1) those that have no solutions, (2) those where solutions exist but are not well known, and (3) those where solutions have been proposed but are incorrect. We conclude in stressing where new research is needed to address these challenges. 相似文献

Intensive agricultural systems interact strongly and reciprocally with features of the lands they occupy, and with features of the societies that they support. We modeled the distribution of two forms of pre-European contact intensive agriculture – irrigated pondfields and rain-fed dryland systems – across the Hawaiian archipelago using a GIS approach based on climate, hydrology, topography, substrate age, and soil fertility. Model results closely match the archaeological evidence in defined locations. On a broader scale, we calculate that the youngest island, Hawai'i, could have supported 572 km2 of intensive agriculture, 97% as rain-fed dryland field systems, while Kaua'i, the oldest island, could have supported 58 km2, all as irrigated wetland systems. Irrigated systems have higher, more reliable yields and lower labor requirements than rain-fed dryland systems, so the total potential yield from Kaua'i (49k metric tons) was almost half that of Hawai'i (97k metric tons), although Kaua'i systems required only 0.05 of the agricultural labor (8400 workers, versus 165,000 on Hawai'i) to produce the crops. We conclude that environmental constraints to intensive agriculture across the archipelago created asymmetric production efficiencies, and therefore varying potentials for agricultural surplus. The implications both for the emergence of complex sociopolitical formations and for anthropogenic transformation of Hawaiian ecosystems are substantial. 相似文献

Was Derry's independent city police force wholly inadequate, was it just inefficient for the suppression of riots; or was it the demonstration of politico-religious partisanship that ensured the force's abolition in 1870? This paper will attempt to explore and answer these three questions. It will also look at the borough force in some detail, examining issues with regard to the force's pay, discipline, its duties and conditions of service. It will not attempt to analyse Derry's nineteenth-century riots or the political and sectarian issues surrounding these riots, except where aspects of these directly affected the borough police. 相似文献

Women's farm work and the gendered nature of the farm space and farm practices have been important intersecting themes within feminist enquiry over the last 30 years. Much research has tended to underplay the wider evolution of these gender relations – leaving under-explored the longer-term formation and contestation of the gendered activities, spaces and identities observed in the present. This article draws on research on 64 farms in the Peak District (UK) to take a wider temporal view of farm gender relations. Utilising a farm life history approach the article considers three key moments within farming histories to explore the active role(s) played by women in shaping farms and farming practices. In doing so the article adds complexity and nuance to understandings of both processes, such as the ‘masculinisation’ of agriculture, and to the gendered geographies of the farm space. 相似文献
