As wildfires increase in both severity and frequency, understanding the role of risk saliency on human behaviors in the face of fire risks becomes paramount. While research has shown that homebuyers capitalize wildfire risk following a fire, studies of the role that risk saliency plays on residential development is limited. This paper aims to fill this gap by studying the link between wildfire risk saliency and the rate of residential development in wildfire-prone areas, by treating recent wildfires as conditionally exogenous shocks to saliency. Using geospatial data on residential development in Colorado, we show that saliency shocks due to wildfire lead to statistically significant reductions in the rate of new development in wildfire risk zones that last upwards of 5 years, a result that is robust to a number of alternative explanations. We explore the policy implications of these findings, noting that education on fire risks may curtail some but not all of the development in these high wildfire-risk areas due to the rapid growth of development in these regions.  相似文献

The use of red iron‐based earth pigments, or ochre, is a key component of early symbolic behaviours for anatomically modern humans and possibly Neanderthals. We present the first ochre provenance study in Central Europe showing long‐term selection strategies by inhabitants of cave sites in south‐western Germany during the Upper Palaeolithic (43–14.5 ka). Ochre artefacts from Hohle Fels, Geißenklösterle and Vogelherd, and local and extra‐local sources, were investigated using neutron activation analysis (NAA), X‐ray diffraction (XRD) and scanning electron microscopy (SEM). The results show that local ochre sources were continuously and systematically accessed for c.29 500 years, with periodic events of long‐distance (about > 300 km) ochre acquisition during the Aurignacian (c.35–43 ka), suggesting higher mobility than previously suspected. The results reveal previously unknown long‐term, complex spatio‐temporal behavioural patterns during the earliest presence of Homo sapiens in Europe.  相似文献

Traditionally, geographic research and engagement with Indigenous communities have largely been developed within a western research paradigm and have historically been linked to colonial practices such as extraction and/or domination. The consequences of these research practices and paradigms have been the further marginalisation of Indigenous people globally. However, geographers are increasingly being influenced by a range of Indigenous scholars from both within and beyond the discipline who highlight the colonial foundations of geographic knowledge and the ongoing production of colonial relations, and who are calling for a decolonisation of knowledge through the use of Indigenist methodologies. After exploring this shift, this paper moves to a discussion of my engagement with research in Indigenous communities using Indigenist methodologies, including the emotions and thought processes that emerged during my own research journey, which led me to southern Guyana and the Makushi and Wapishana peoples who reside in the northern savannah environments of the Amazon basin. I conclude by sharing how I am continuing that journey using Indigenist approaches in my work in the Madre de Dios region of Peru, and by encouraging future scholars to challenge traditional geographic research methods.  相似文献

In this article I examine three calls for Western support for girls' education in the ‘developing world’. Using transnational feminist theory and discourse analysis I look at three examples of these calls; Three Cups of Tea, ‘Because I Am a Girl’ and the United National Girls Education Initiative. I suggest that what Mohanty (1988) terms the ‘Third World Woman’ – a homogeneous, static image of women in the third world – is the spectre used to motivate Western support. Through representations of girls, Western viewers/readers are hailed to invest in order to save the girl-child from the haunting ‘Third World Woman’. The girl-child, through her particularity as a girl, her future womanhood as motherhood and her neoliberal potential, becomes presented as emblems of a better future with the investment of Westerners.  相似文献

The results of the X-ray fluorescence (XRF) analysis of 59 obsidian samples from 11 archaeological sites in the Auca Mahuida region of north-western Neuquén, Argentina, are present. They indicate that several obsidian sources were used; however, the intensities of their exploitation were variable. Strong differences appear between the Colorado River basin, characterized by a low variability of obsidian groups from northern Neuquén; the Auca volcano, with a low variability of obsidian groups, but from local sources located north and southwards of the study area; and along Bajo del Añelo, which presents a high variability of obsidian groups from several local and non-local sources. The pattern recorded fits different mechanisms of access to the sources and the conveyance of obsidian across the landscape. Two distinct paths of direct access are suggested for obsidian availability along the Colorado River in northern Neuquén and for Portada Covunco obsidian in central Neuquén. Additionally, the presence of obsidian from sources in southern Neuquén province (Cerro Las Planicies-Lago Lolog), located about 350 km from the study area, is suggested. While not yet conclusive, this possibility parsimoniously integrates the available geochemical and spatial information, allowing the existence of either long-distance transport or indirect access by exchange or similar mechanisms to be proposed.  相似文献

This article focuses on the reign of James II of Scotland (1437–1460) and argues that the Scottish king deliberately attempted to gain a monopoly over chivalry as part of his assertion of royal power. In seeking to integrate the historiographies of state-building and chivalric culture in fifteenth-century Scotland, what is offered here is an account of the principal strategies employed by James II to establish royal authority throughout Scotland, and an assessment of the various means in which chivalry was being patronised and promoted by the Scottish nobility and the political challenge inherent in this activity. James's response to this challenge is examined through a series of incidents in the 1450s and, in this manner, seeks to rethink the role of chivalry in late medieval Scotland. Far from being a peripheral cultural practice, this article argues that it should be seen as an integral part of James II's state-building agenda.  相似文献
