The evacuation of a quarter of a million residents of the city of Mississauga, Ontario, in the aftermath of the derailment of a freight train carrying hazardous materials on 10 November 1979, was, at that time, the largest peacetime evacuation ever conducted in North America. It took place with little panic or injury, no deaths, and no apparent resistance to evacuation advice. Not surprisingly, then, the success of the Mississauga evacuation has attracted the interest, and raised the hopes, of emergency planners, governments, and industry officials in North America and many other countries. These groups want to understand the reasons for the success of the evacuation, and, if possible, to transfer the effective elements of the Mississauga emergency plans and response procedures to their own jurisdictions. Their concerns reflect the wider search for a model of public decision-making under threat which would identify and link cirtical factors, decisions, and behaviour, and which would provide a framework for emergency planning and research. 相似文献

In Colombia’s agrarian spaces, war and extractivism are deeply entangled. Almost four years after the peace accords signed between the national government and the FARC guerrilla, post-conflict geographies are best characterised by the ongoing dispossession of local populations related to the entrenchment of extractivism. Drawing from ethnographic work carried out in the Colombian Caribbean on the ordinary practices and spaces of social reproduction, the ordinary geographies, this article explores gendered practices of care and their role in both sustaining and disrupting paramilitary violence and agrarian extractivism. The focus not just on the gendered effects of war and extractivism, but on gender’s constitutive role in the configuration of these processes and dynamics, allows us to contribute to recent literature on extractivism, dispossession and violence from a feminist standpoint. 相似文献

论文分不同时期阐述了中国穆斯林移民马来西亚的历史,通过实证调研数据突出了穆斯林跨国流动与穆斯林世界的教育和贸易之间的密切联系,并对"侨乡"流动模式和"回族"流动模式进行了分析比较。认为有关华人移民的研究主要局限于地理(侨乡移民)或阶级(苦力、企业家或学生移民)方面。这些研究隐含一个不言而喻、理所当然的假设,即中国的移民都是汉族,少数民族被封闭在偏远的边疆地区,因而是不流动的。但研究显示,自1978年起,中国穆斯林少数民族无论是在跨境迁移——这在维吾尔族和哈萨克族等穆斯林少数民族中尤为突出,还是在远程的跨国迁移——在回族中尤其明显,都具有异常高的流动性。回族穆斯林少数民族的生活穿梭于中国民族国家和跨国穆斯林世界之间。宗教在回族穆斯林流动决策和流动模式中有重要作用。 相似文献

Prehistoric pottery decorated with incisions or impressions filled with white and seldom coloured inlays is well documented in the archaeological literature, but the related in-depth archaeometric studies are sporadic. 43 decorated ceramic shards, dating from the Neolithic to the Bronze Age, and an Iron Age fibula from the archaeological site of Castello di Annone (Piedmont, North-Western Italy) were analysed with FTIR, Raman and XRPD for characterization of the ornamental pigments forming these inlays. Few white components were used as fillers, namely talc and bone ash (hydroxyapatite – Bone White), often as a mixture and seldom accompanied by other pigments (i.e. kaolinite and presumably secondary calcite). Comparison with freshly-heated biogenic hydroxyapatite proved that ancient Bone White pigment was calcined at about 900 °C. Such a process was kept separate from pottery firing as these white mixtures show absence of talc degradation by-products and sporadic presence of kaolinite, implying these ceramics were decorated only after firing in furnace. Actual presence of fluorapatite in bone ash could allow dating with the Fluorine Method, but lack of fluorine detection with SEM-EDS causes such an attempt to be impracticable so far. A pilot comparative study with a restricted but representative group (11) of coeval finds from other sites of Piedmont suggests that while recurrence of talc prevails in Castello di Annone from the Neolithic throughout the Bronze age, massive use of bone ash (Bone White) becomes widespread in the close Iron Age settlements, possibly consequent to a more efficient handling of its production technology. 相似文献

Most studies that incorporate a gender dimension into the study of poverty or other development outcomes focus on the sex of the household head. This article argues that a headship analysis gives only a partial view of gender inequality since it does not take into account the position of women within male‐headed households. Drawing primarily on the Living Standard Measurement Studies for Latin America and the Caribbean, the authors present baseline indicators of the degree of gender inequality in asset ownership for the eleven countries in the region that have collected individual‐level data on asset ownership. Disaggregated data on asset ownership within households suggest that the distribution of property by gender is more equitable than a headship analysis alone would imply. But the degree of gender inequality also varies according to the specific asset and among countries. Further comparative work on asset ownership requires attention to the marital regimes governing property rights in marriage. Finally, the authors suggest how household surveys could be improved by standardizing the collection of individual‐level asset data across countries. 相似文献

We examine evidence for prehistoric diet in the Fiji Islands through the analysis of stable isotope ratios (δ13C and δ15N) for 26 samples of human and animal bones from various archaeological sites, time periods, and local environments. The oldest individuals in this study, dating to about 2700 BP and living on the small island of Waya, consumed a predominantly marine-based diet. Subsequent populations on this island showed reduced consumption of marine resources, with greater reliance on terrestrial ones, throughout the cultural sequence. In contrast, populations of humans and pigs living inland on Viti Levu, the largest island, relied on terrestrial resources since at least 1500 BP. Thus, our results suggest that human and pig diets throughout Fijian prehistory relied variably on marine or terrestrial resources, and this distinction is largely a product of geography. This finding and our analyses provide a model for understanding ancient diets in Remote Oceania. 相似文献
