One consequence of the expanding road network and its associated traffic is increased levels of traffic noise. While the hedonic literature has consistently found a negative relationship between real estate prices and noise levels, research in the United States has typically relied on crude measures of traffic noise. Here, we reduce the measurement error of traffic noise exposure through a detailed model of noise propagation over the landscape. We then estimate the hedonic relationship between noise and single family house prices using over 40,000 transactions throughout the St. Paul, Minnesota, urban area from 2005 to 2010. We implement spatially and temporally flexible local regression techniques and find significant nonstationarity in the hedonic function over time and space.  相似文献

Recent investigation and a firm tree-ring date have made it possible to place this well-known early fourteenth-century building more securely in the chronology of the development of the medieval hall-house. It shows some of the characteristics of early manorial complexes comprising various discrete domestic units but well advanced towards the classic arrangement where the principal accommodation is concentrated within a single structure. Its overall design and dimensions suggest that it is the work of an architect who probably operated from an ecclesiastical workshop.  相似文献

SUMMARY: In 1842 the former first government house located at Okiato, New Zealand, burnt to the ground and the site was abandoned. A well on the site was excavated in 1994–95, revealing a base layer of burnt timbers, a Maori digging stick and ceramic sherds with an estimated manufacture date range of 1823–41. We argue that this deposit is derived from the 1842 destruction of the Okiato government house building. An analysis of the wood identified kauri (Agathis australis) and kahikatea (Dacrycarpus dacrydioides), confirming that the building was not a prefabricated imported structure, but rather was constructed on site from locally available timber.  相似文献

This article examines the motivations, institutions and processes involved in colonial knowledge formation through a study of the missionary William Burton. It considers Burton’s work on the Luba of Katanga in relation to the practices of Belgian colonial science and Anglo‐Saxon social anthropology. The essay discusses why missionaries engaged in ethnographic research when they were so intent on changing the customs and beliefs they described and why Burton in particular did not get the recognition he deserved as an authority on his subject. The article charts Burton’s shifting attitude toward the Luba, showing how he moved from an aggressive intrusive mode of research to a position of greater sympathy as he came to consider their cultural riches through study of language, proverb and folklore. Consideration of the second phase of Burton’s research opens up discussion of the missionary origins of the disciplines of African theology and African religious studies.  相似文献

Land tenure and food security have each been the subject of extensive—but generally separate—research in the past. Links between the two issues are now receiving increased attention, yet critical links between them remain unexplored. After a brief review of the two concepts, this article combines both issues within a dynamic framework that recognizes not just the conventional link between access to land and access to food in the short run, but also the recursive link between access to food and the ability to maintain sufficient resources to meet long-run needs. Such a framework makes explicit the trade-offs that poor households may face in bad years between consumption and investment in non-labour assets. Perhaps less intuitively, it also suggests that the need for self-insurance may force poor households to choose less efficient crops or production strategies than wealthier households even in good years. The article concludes with a discussion of the implications of these results for equity, efficiency, research, and policy.  相似文献

Despite cultural similarities between Canada and the United States, some observers contend that significant differences remain in attitudes and values between the two countries. For example, Lipset has observed that “efforts to distinguish Canada and the United States almost invariably point to the greater respect for law and order and those who uphold it north of the border”. Lipset’s argument is that Canadian values are based on the nation’s founding principles of “Peace, Order and Good Government” while American values stem from the country’s revolutionary origins and are based on the values of “Life, Liberty and the Pursuit of Happiness.” We test Lipset’s observations, and those of some of his critics, using parallel surveys administered to university students in two institutions on either side of the Canada–US border. This is a very demanding test of his arguments so the supportive evidence we uncover for his arguments is significant.  相似文献

Sites which have been occupied semi-continuously in the past present some inherent difficulties for archaeology. Here we present new research from a coastal site on the North Island of New Zealand at Cooks Beach where anthropogenic vegetation changes are seen using microfossil analysis of obsidian tools, sediments and pit fill. The results indicate the initial presence of people in AD 1300–1400 followed by subsequent periods of disuse or abandonment and sweet potato (Ipomoea batatas) cultivation. Around the time of initial settlement, obsidian from this location is found at sites across the country. After AD 1400 the area appears to be deserted for a century or more, after which we see evidence for the cultivation of sweet potato in AD 1500 as evidenced by extensive soil modification and numerous storage pits. There is no evidence of a permanent settlement at the site. The geographic distribution of Cooks Beach obsidian was constricted while the site was used for sweet potato cultivation, a pattern often attributed to increased warfare. It appears cultivation was abandoned after AD 1650 marking a second secession of use, a fact confirmed in AD 1769 when Captain Cook visited the area. We consider the possible drivers for the late abandonment of cultivation at Cooks Beach.  相似文献
