Many research studies have examined if hazardous waste treatment, storage, or disposal facilities (TSDFs) tend to be located where people are disproportionately minority, low-income, and politically inactive. This article focuses on whether variables representing potential neighborhood activism were related to where new TSDFs located during the 1990s. My analyses demonstrated that there is no consistent, substantial evidence that the demographic characteristics of neighborhoods around new TSDFs affected their location decisions. The overall composition of these neighborhoods indicates that there are disproportionately high concentrations of minority and low-income people around these TSDFs and disproportionately fewer people who were more likely to be politically active and concerned about new TSDFs. The shew towards more minorities was overwhelmingly due, however, to a relatively small number of TSDFs in heavily populated neighborhoods with high minority proportions. 相似文献

This article explores progress being made in the sphere of integrated rural development in Northern Ireland, based on the experiences of 15 LEADER II local action groups. Research suggests that the local action groups experienced difficulties in developing integrative and multi-dimensional approaches to rural development during the initial stages of strategy formulation. In addition there appears to have been an emphasis on delivering the products of rural development with little importance attached to supporting processes such as capacity building and animation. However, as the programme progressed, this article examines the potential added value of LEADER II in Northern Ireland as demonstrated by the enhanced scope for cross-sector dialogue and local collaboration rooted in partnership based activity. 相似文献

ABSTRACTThis paper considers the contribution made to transport geography research at the University of Aberdeen over the last century. In section one, the earliest work in transport geography emphasised the physical connectivity provided by transport through infrastructure networks. Section 2 discusses the contribution made at Aberdeen to debates around accessibility and connectivity. This work had a strong rural dimension and evidenced a growing recognition of the importance of technology in transport. It provided the springboard for research on digital connectivity with important contributions to the wider domain of transport studies in the fields of flexible transport, rural connectivity, transport and energy and social media and big data as reported in Section 3. Section 4 brings the story of transport research at Aberdeen up to the present. It frames research under the banner of intelligent mobility (IM), which links technology and mobility to the wider societal objective of enabling the smarter, greener and more efficient movement of people and goods. Contributions are reported to the fields of shared mobility, smart rural mobility, transport security and privacy and accessibility. Finally, a return to the theme of infrastructure networks and connectivity is highlighted in work on global production networks in aviation. 相似文献

ABSTRACT Kettle Falls, located 1125?km from the mouth of the Columbia River in present-day Washington State (USA), was the second-most important salmon fishing and trading locus on that river in the early historic era. We encapsulate the late Holocene history of the fishery by deriving a summed probability distribution function (SPDF) from 50 radiocarbon ages from 13 archaeological sites within 2?km of the falls. When compared to an SPDF from 307 sites from elsewhere on the Columbia Plateau, and a null model, the Kettle Falls SPDF exhibits two phases of elevated activity at 1700–1300?cal BP and 800–500?cal BP, and an intervening lull. These phases are not related to the excavation history or differential exposure of sites to taphonomic processes, but they are concordant with episodes of glacial advance in the local mountains, which reflect hemispheric-scale changes in climate. Modern returns of summer-run Chinook salmon to the Columbia River are inversely correlated with sea-surface temperature regimes in the northeast Pacific Ocean, and we propose that the occupational history of the Kettle Falls fishery echoes long-term variations in the returns of salmon to the upper Columbia River linked to climate change. 相似文献

Labour migration to and from two preindustrial villages in Japan is examined over nearly three-quarters of the nineteenth century. The history and geography of migration are related to local and regional conditions, and to natural events. Natural disasters are demonstrated to offer the best single explanation for much of the movement of labour. 相似文献

Transparent obsidian artifacts have been reported for the northern Lake Titicaca Basin. Based on instrumental neutron activation analysis (INAA) of these artifacts a distinct chemical group was identified. Yet, the location of the source of transparent obsidian in the southern Andes remained unreported in the archaeological literature. This paper reports on the chemical composition and geographic location of a source of transparent obsidian from the Macusani region of Peru. Through the use of INAA and portable X-ray fluorescence (PXRF) we demonstrate that Macusani obsidian or macusanite comprises (at least) two chemical groups. One of these groups was used for making artifacts during the Archaic Period. Artifacts made of this obsidian were found more than 120 km from the source and yet, one-third of the obsidian artifacts encountered at Macusani were from the non-local source of Chivay which is 215 km to the southwest. 相似文献
