Identifying integrated urban areas is an important issue for urban analysis and policy evaluation. In this article, we provide a set of FUAs suitable for monitoring urbanization in Ecuador, a less developed country without commuting data. We do so substituting such socioeconomic flows by available information on road structure, which allow us to work with accessibility based on a varying travel time. In order to build Ecuadorean FUAs, we calibrate our methodology considering Colombian data. We perform several sensitivity analysis and robustness checks to Ecuador with alternative sources of socioeconomic flows. We conclude that the use of GIS data and the calibrated thresholds provide a set of FUAs similar to the ones that would result of using commuting information. 相似文献

Exported peanuts have been a key source of state revenue and rural incomes in Senegal since the early 20th century. Senegal has among the world's highest rates of liver cancer incidence. From the 1960s, aflatoxin - the toxic metabolite of fungal strains to which peanut plants are vulnerable - was suspected to be a cause of this cancer. Aflatoxin has since been classified and, in markets that import Senegalese peanuts, regulated as a carcinogen. This article situates aflatoxin toxicity amid the traces of Senegal's century-old peanut export economy. Examining how peanuts have transformed and inhabit soil, landscapes, buildings, food, bodies and aetiological knowledge, it suggests ways in which aflatoxin as well as uncertainty about its carcinogenicity might be cast as residues of a market-oriented economy. 相似文献

ABSTRACT This article examines policy responses in Canada and the US to the shale revolution and changing North American oil and gas markets. We outline the effect of the shale revolution on North American oil and gas markets, and how the subsequent energy policy choices in each country changed the relationship between Canada and the US. In the US, increasing production, combined with the policy imperative of maintaining energy security, led to less support for Canadian supply and the subsequent on-off-on saga of the Keystone XL pipeline. In Canada, growing concern about the balance between the environment and the economy led to stalled pipeline development and reform of regulatory systems, problems exacerbated by the new policy direction in the US. 相似文献

Despite a cascade of corruption scandals over the last decade, the role of political corruption has yet to be accounted for in the scholarship on Spanish urban entrepreneurialism. This is an omission that extends to the broader literature on the topic as well. This paper looks at the theoretical causes of this neglect and explores ways of integrating corruption into the study of urban entrepreneurialism. To do so, it offers a systematic analysis of the role of clientelism in the political economy of Spanish inter-urban competition. Contrary to the existing literature, which at best explains away corruption as a logical outgrowth of intensified competition for real estate capital, this paper argues that corruption is rooted in a political structure that precedes the emergence of urban entrepreneurialism. This structure is identified as an “iron triangle”, a complex of colluding interests formed by the state, the real estate industry, and political parties. 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

This paper presents the results of a pilot study using dental microwear analysis on 23 sheep and goat teeth dated to the 6th century BC from the Iron Age site of El Turó Font de la Canya (Barcelona, Spain). This study aimed to reconstruct livestock management practices and landscape use. The dental microwear pattern indicates that sheep and goats could have been grazing in the same area where vegetation was composed of shrubs, bushes and non-graminaceous plants on an eroded landscape, although additional supplies of fodder cannot be excluded. This scenario is compatible with the archaeological and palaeoenvironmental data which suggest a possibly increased territoriality, land degradation and an increase of woodland clearance during Iron Age in the North-east of the Iberian Peninsula. Furthermore, we applied two recent microwear approaches which provide more information about mortality events and the possibility of distinguishing between an intensive and extensive management. This paper demonstrates how this method can be used to better understand animal husbandry practices and landscape use in Late Prehistory. 相似文献

In 1952, María Rosa Lida de Malkiel published a work in Sur magazine about the literary sources of Jorge Luis Borges. In the second paragraph of that work she relates a passage from one of the Argentine's stories with a verse from the Aeneid and, later on, two verses of the poem “Las calles” with some others from Lucretius' work De rerum natura. In both cases, she cites the number of the book and verse of the Latin poets. The one referring to Virgil is correct; however, Lucretius' verses are apocryphal. In this work, I analyze the reasons the eminent philologist could have had to carry out tremendous artifice and, at the same time, the objective and personal qualms that, during the revision, produced the auctoritas of her figure. 相似文献
