This paper argues that critical geographies of Latin America begin with an analysis of how and why the bodies and geographies of geographers themselves matter. To focus on the geographer as a producer of knowledge is not to advocate the kind of navel gazing so abhorrent to many scholars. Rather, it is an effort to call attention to and critically assess how the geographer's embodied social position and geographic location inform the production of knowledge about and representations of Latin American people and nature. To illustrate how and why bodies and geographies matter, I draw from feminist and post-colonial theory and include examples from my own experiences and those of other researchers doing fieldwork in Latin American countries. I conclude by exploring the notion of situated knowledge as a tactic that writes bodies and geographies into academic texts. Ultimately, situating knowledge represents a political intervention and contribution to the broader goals of emancipatory politics shared by critical human geographers.  相似文献

Flowers in the bathtub: boundary crossings at the public-private divide   总被引:2,自引:0,他引:2  
Nicholas Blomley 《Geoforum》2005,36(3):281-296
Legal spaces are said to be a crucial materialization of law, serving to communicate legal meaning and, in so doing, helping to produce a liberal-legal consciousness. Given its centrality to legal ordering and liberal ideology, the spatial manifestation of the public-private divide, especially when related to property, would appear to be particularly important in this regard. Public and private are assumed to be both mutually exclusive and exhaustive. Drawing upon empirical research conducted in a neighbourhood in Vancouver, Canada, I argue that spatial and legal categories such as public and private may be more fluid than one might suppose. While the public/private divide is clearly powerful, and informs much policy and governmental action, it is not necessarily the case that it has the purchase on everyday life that some scholars have suggested. People may live in more complicated and overlapping worlds when it comes to supposedly determinate categories such as property.  相似文献

空间分析与自然地理综合研究   总被引:2,自引:1,他引:2  
通过对空间分析技术和自然地理综合研究发展历程与趋势的分析,得出两个结论:1)现代地理学的快速发展越来越离不开空间分析的支撑,即空间分析技术在地理学中的应用空间愈来愈广,在自然地理综合研究中尤为如此,其主要原因就是空间分析在综合研究中的优势愈来愈明显;2)空间分析技术随其理论与实践的迅速发展及逐步拓展,愈来愈成为自然地理学发展的巨大推动力,也越来越离不开自然地理综合研究这个促使其发展壮大的空间和能发挥其主导作用的领域。空间分析技术和自然地理综合研究的结合已经成为现代自然地理学以及地球空间信息学研究的主要发展趋势之一。  相似文献

The proliferation of soybean monoculture and its expansion into previously marginal territories in Argentina have resulted in land conflicts and attacks on peasant communities that possess land without having secured tenure. However, the rapid and intensive modernisation and industrialisation of agriculture production has had differentiated effect on different territories in Argentina. This article posit that understanding these differences requires an extended temporal analysis. While social research tends to focus on the present or recent past, this paper joins calls for greater attention to historical context and processes when examining current social dynamics and geographies. Focusing on the province of Santiago del Estero in Northwest Argentina, this paper provides a particular temporal-thematic approach for conducting such a historical path analysis, which here focuses on the province’s changing agrarian structures and political shifts that resulted in a complex, irregular and subsequently unstable land tenure system.  相似文献

This article follows the industry employment histories of all individuals who at some point have been affiliated with the declining German or the dismantling Swedish shipbuilding industry during 1970–2000. We analyse the situation of the individual workers leaving shipbuilding, investigating the extent to which they were employed at all, tended to move to related sectors within or outside the region, and whether such moves were beneficial for the individuals. Combining insights from labour geography and redundancy studies with evolutionary economic geography, we find remarkably similar results for the West German and Swedish cases. Our findings indicate a notable impact of the regional industry structure on the labour market outcomes for workers leaving shipbuilding. This suggests that more attention should be devoted to the specific structures of the absorptive capacity of regional labour markets. The findings are discussed within the context of a mature industry.  相似文献

Legal processes shape how water resources are allocated, regulated, distributed, and governed. This paper examines the public trust doctrine, a legal principle that addresses the state’s role in governing natural resources by requiring states to manage certain bodies of water and their shorelines for the good of the public. The paper focuses on how the public trust doctrine has been used—with varying degrees of success—to protect water bodies by contesting the diversion and transfer of water in California. The paper compares how the doctrine was applied in two cases: Mono Lake and the Salton Sea, two California lakes that have been threatened by water diversions and transfers. Advocates at Mono Lake successfully used the public trust doctrine for environmental protection, while public trust was an unsuccessful strategy at the Salton Sea. The paper examines issues of nonequilibrium ecosystems, natural versus artificial ecosystems, and wasteful versus reasonable uses of water.By investigating why one case was deemed eligible for public trust protections while the other was not, this paper examines how discursive constructions of nature are embedded in and enacted by legal institutions and how these constructions of nature impact the implementation of legal protections of natural resources. In examining the use of the public trust doctrine in California, the paper examines both the potential and the limitations of the public trust in practice, showing how legal processes and institutions can be used to protect public interests in natural resources but also how particular environmental narratives are reinforced through these institutions.  相似文献

This paper is based on 6 months of ethnographic, multi-sited research in Malaysia, and investigates the relatively recent phenomenon of edible birds’ nest farming in urban areas (‘swiftlet farming’). Swiftlet farms are typically converted shophouses or other buildings which have been modified for the purpose of harvesting the nests of the Edible-nest Swiftlet (Aerodramus fuciphagus). I use the controversy over urban swiftlet farming in the Malaysian city of George Town, Penang, to examine discourses used by key stakeholders to shape debates over the place of non-human animals in cities. By considering everyday experiences of urban swiftlet farming, I explore how this burgeoning industry is perceived amongst residents, and how it is deemed to be (in)appropriate within the political, economic and cultural landscape of George Town. Yet, I also consider how farmers have sought to contest these discourses on ideological and normative grounds. In so doing, I place the cultural animal geographies literature in conversation with emergent literature on landscape and urban political ecology. Such a framing allows for a critical evaluation of the controversies surrounding this case, and their implications for human-animal cohabitation in cities. The paper reflects on the implications of this case for how we regulate human-animal relations and live in contemporary cities, and the crucial role of animals in altering urban form, aesthetics and everyday life, particularly in non-Western contexts.  相似文献

在短期基坑沉降监测中,由于数据量少且呈非线性变化,沉降模型很难准确建立。灰色GM(1,1)对数据少、趋势性强、波动小的数据有较高的预测精度,但不能模拟复杂的非线性函数;BP神经网络可以对非线性数据进行学习训练,具有自学习、自适应能力;通过将GM(1,1)与BP神经网络组合,并优化网络部分的学习率、权值和阈值等,建立一种改进的灰色神经网络模型,该模型具有对非线性数据自学习、自适应能力和预测精度更高等优点。通过某基坑沉降监测分析,验证改进的灰色神经网络模型预测精度更高,适合短期建模,具有很好的实用性。  相似文献

针对盾构施工参数变化对施工引起的地表变形的重要影响,该文构建了盾构施工参数与地表沉降变形关系模型。以北京市某地铁盾构区间施工过程中的实测数据为基础,分析了不同盾构施工参数与地表沉降变形的关联度和相关性,得到不同参数对沉降变形贡献值的大小;之后,利用多元回归模型方法建立主要影响参数与地表变形的关系模型,并进行模型的合理性检验;最后,利用该模型得到的沉降量与实测数据进行对比分析,结果显示符合性较好。  相似文献
