Scale and the other: Levinas and geography 总被引：2，自引：0，他引：2
Richard Howitt 《Geoforum》2002,33(3):299-313
This paper seeks to contribute to Geography's recent conversation of identity, landscape, scale and difference. It brings into dialogue previously divergent discussions about space, place and difference and proposes an approach that treats time, space, place and scale as co-equal conceptual and/or analytical elements of cultural landscapes. It argues that many philosophical debates about embodiment, emplacement and difference abstract a universalized notion of `place', `body' and `self' which confounds and conflates scale issues and consequently confuses the dialectical interplay of `time', `space', `being' and `culture' across scales. The paper takes the work of Emmanuel Levinas (1906-1995) and the discursive communities around it as a philosophical entry point into these debates. 相似文献

Over the past two decades development has been shifting its focus toward smaller scales and particular problems. As a result, the household has become an increasingly important institution for development, and has come under increased scrunity as development practitioners and scholars seek to better understand this institution’s functions and foundations, trying to ‘get the household right’. These efforts, rather than clarifying the character and the function of the household, have contributed to its indeterminacy by reifying the very institution they seek to analyse. Arguing that these efforts fundamentally miss the point of examining the household, this paper introduces a different framework of analysis that addresses the household not as a fixed object of research, but as a local construction that embodies flows of power and knowledge both within and transcending the local. Using the example of varying constructions of the household in two villages in Ghana’s Central Region, this article illustrates how such an approach allows us to address the various functions of the household as particular embodiments of these flows, an approach that better explains the endurance or ephemerality of these functions. Such an approach provides a stronger foundation for the consideration of how particular constructions of this institution may have troubling implications for issues like gender equity and sustainability. 相似文献

Meteorite impact structures are found on all planetary bodies in the Solar System with a solid surface. On many planets, impact craters are the dominant landform. Earth's active geology, however, tends to rapidly erase impact structures from the geological record, although we know currently of 174 confirmed impact sites. Impact events are destructive and have been linked to at least one of the 'big five' mass extinctions over the past 540 Ma. But they also provide certain economic benefits, including the formation of metalliferous ore deposits and hydrocarbon reservoirs. Impact structures can also form new biological niches, which can provide favourable conditions for the survival and evolution of life. Despite this, it was only in the past 40 years that the importance of impact cratering as a geological process was recognized and only during the past 15–20 years that the study of meteorite impact structures has moved into the geological mainstream. There is, therefore, still considerable potential for new and exciting advancements. 相似文献

Contaminative mine drainage waters have become one of the major hydrogeological and geochemical problems arising from mankind's
intrusion into the geosphere. Mine drainage waters in Scandinavia and the United Kingdom are of three main types: (1) saline
formation waters; (2) acidic, heavy-metal-containing, sulphate waters derived from pyrite oxidation, and (3) alkaline, hydrogen-sulphide-containing,
heavy-metal-poor waters resulting from buffering reactions and/or sulphate reduction. Mine waters are not merely to be perceived
as problems, they can be regarded as industrial or drinking water sources and have been used for sewage treatment, tanning
and industrial metals extraction. Mine-water problems may be addressed by isolating the contaminant source, by suppressing
the reactions releasing contaminants, or by active or passive water treatment. Innovative treatment techniques such as galvanic
suppression, application of bactericides, neutralising or reducing agents (pulverised fly ash-based grouts, cattle manure,
whey, brewers' yeast) require further research.

The fundamentals of stratigraphy have been well understood for more than three centuries and there is now a detailed stratigraphical record reaching back more than one billion years. But this sedimentary rock record is everywhere unpredictably incomplete and yet everywhere similar in its layered character. Computer analyses now reveal the fundamental nature of these two aspects of the record: gaps and layers are governed by simple, seemingly universal, laws that operate regardless of age and sediment type. 相似文献

Security and the future: Anticipating the event of terror 总被引：1，自引：0，他引：1
Ben Anderson 《Geoforum》2010,41(2):227-235
This paper explores the relation between processes of security and futurity in the context of efforts to govern the complexity and contingency of events of terror. It argues that processes of securing function by generating a dangerous or promissory supplement to the present that thereafter propels the extension of forms of security. The paper develops this argument through an example of how an event of terror was anticipated: a RAND exercise into the aftermath of a ‘ground burst’ nuclear explosion in Long Beach, California on March 14th 2005. It argues that exercises (in)secure through three quasi-causal operations, each of which render events of terror actionable and result in specific relations between the present and future. First, ‘hypothetically possible’ generic events are named. The future takes place as a threatening horizon. Second, the defined phases of an event’s happening are staged (an advent, its multiplication into a crisis in the context of a milieu, and a response/recovery phase). The here and now is suspended between an ‘as if’ future and the present. Third, the consequences of the event are played. The future is both an intensified ‘practical’ presence embodied by exercise participants and an outside that exceeds attempts to definitively know it. The conclusion summarises the implications of the paper for work on futurity, security and the event. 相似文献

The paper examines the pressures being exerted by cultural and economic processes upon African cultures in the intermediate zone of the Sudan. It examines in particular the experience of the Ingessana and Uduk peoples living between the White and Blue Niles. The Uduk have experienced the greater degree of disruption from Sudan's civil war, and many Uduk have sought refuge in Ethiopia. The Ingessana are in the frontline facing cultural and economic pressures from the north. To pressures for Islamisation and Arabicisation have been added the development of chromite mining, mechanised agriculture and increased nomadic activity around their hills.The paper points out the advantages of cultural adaptation and survival, rather than acculturation, to both these peoples and the Sudan and concludes that the Ingessana seem particularly likely to adapt and survive as a cultural entity. 相似文献

The map is to geography what verisimilitude is to the history of the novel: the visual dominance of the one, and the omnipotent realism of the other, are powerful tools for representing a city like nineteenth century London. Dickens's of London may have relied on verisimilitude, but it did so in a way that transgressed its own terms of reference, questioning reference even as landmarks and signposts. The geographer's map may illustrate reference points, St. Paul's and the Monument, but in Dickens no objective totality is established for the reader. Instead a constellation of named places becomes representative of the reputed governance of the city as a whole. Dickens's landscape simultaneously establishes and transgresses the half-secured foundations of the relationship between individuals and the environment. Contrats and contradictions are multiplied in crowd symbols, caricatures, and historical reversions. Verisimilitude and the visible are representative of the way in which Dickens sought to penerate the opaqueness of the city of crime and cholera. The figure that best illustrates Dicken's coming to terms with the city is the diligent detective probing every obscure nook and cranny. He shows how verisimilitude acts in the service of the relationship between the visible and the opaque. 相似文献

Iceland is a special volcanic island in an anomalous ocean basin. A review of the unusual features shows that among others topography and gravity are broadly positive, spreading has been and still is complex, seismicity is slightly diffuse and the chemistry of the basalts is different from that at normal ridges. In summary we observe a tendency of lithospheric dispersal and spreading in the North Atlantic and its surroundings. These observations together with what is known about Icelandic crust, heat flow, tectonic history, etc., point to a hot mantle upwelling beneath Iceland. The shape of the upwelling currents is not known. Although at present much speculation is possible, the authors prefers to think of a broad rising region uplifting the lithospheric plates such that they tend to slide away from Iceland more forcefully than is the case from normal spreading ridges. 相似文献

Palaeosols are ancient soils formed in sedimentary successions between events of sedimentation, erosion and volcanic activity. Soil formation is regulated by circumstances of climate, vegetation, topographic relief, parent material and time. These factors are quantified by nomopedology, in the form of climofunctions, chronofunctions and other relationships useful for interpreting conditions of the past from palaeosols. In deep time, palaeosols reveal the timing and extent of the Great Oxidation Event of 2.4 Ga. There is also circumstantial evidence for life in palaeosols back to 3.5 Ga on Earth and 3.7 Ga on Mars. These are the oldest known intact profiles, but pieces of palaeosols some 4.56 Ga in age may be represented by carbonaceous chondrite meteorites. Astropedology is the study of very ancient palaeosols and meteorites relevant to the origin of life and different planetary soil systems. Complex chemical assembly, metal catalysis of organic compounds, and the course of hydrolytic reactions as a kind of planetary metabolism make soils an attractive theoretical site for the origin of life. Because dilute solutions tend to an equilibrium that undoes organosynthetic reactions, life is more likely to have arisen on a soil planet like Mars than a water planet like Earth. 相似文献

Abtract The environmental impacts of defence is a neglected and under-researched area for economists. This article presents a conceptual approach outlining some of the economic issues involved in the environmental impacts of defence spending and the activities of the armed forces. It reviews the economics and politics of externalities and then considers beneficial and harmful externalities and concludes by identifying some of the environmental costs of disarmanent. 相似文献

Drawing on findings from a study of Indigenous housing in a regional Western Australian city, this paper examines the experiences of Indigenous peoples as a particular set of ‘right bearers’ within the right-to-the-city discourse. In settler-states, colonial discourses of absence, threat, and authenticity have informed policy frameworks that have militated against various Indigenous claims of belonging, rights, and aspiration in relation to urban places. Housing has been a representative domain of struggle in this respect. Consequently, today, Indigenous peoples have disproportionately high rates of dependence on more volatile and discriminatory forms of tenure than their non-Indigenous counterparts.The paper examines the incongruence between State aspirations to move (Indigenous) people along a housing continuum in urban environments, and the actual experiences of Indigenous urban residents, which fix discursively on barriers to such movements. It also traces the deleterious, displacing impacts for urban Indigenous households of the retreat of the State in its role as a landlord for the socio-economically disadvantaged, and in responding to market signals and particular sociological theses regarding poverty, with specific spatial logics. In so doing, we advance two interwoven arguments. First, we assert that Indigenous people face a unique precarity in the Australian urban housing system, which is a result of both colonial and racially discriminatory forces, and economically discriminating processes such as capital concentration and the commodification of land. Second, we contend that this precarity sets many Indigenous people on housing career trajectories that are antithetical to policy intentions. 相似文献

Compaction localization in the Earth and the laboratory: state of the research and research directions 总被引：1，自引：1，他引：1
Localized compaction in porous rocks is a recently recognized phenomenon that has been shown to reduce permeability dramatically.
Consequently, the phenomenon is relevant to a variety of technologies involving fluid injection or withdrawal. This article
summarizes current understanding of localized compaction and impediments to further progress. The article is based on discussions
at a small workshop on localized compaction sponsored by the Office of Science, U. S. Department of Energy. 相似文献

A relationship between globalization, cities and immigration is increasingly apparent. Whether one is trying to understand Dubai, Toronto, or London, immigrants are culturally, economically, and spatially changing cities in significant ways. This study compares the roster of world cities with that of major urban immigrant destinations. The number of major urban immigrant destinations is growing due to the acceleration of immigration driven by income differentials, social networks and various state and local policies to recruit skilled and unskilled labor and replenish population. This study will present urban-level data on the foreign-born for 145 metropolitan areas of over 1 million people. It will focus on the world’s 19 metropolitan areas with over 1 million foreign-born residents. Analysis of the data suggests that there is a range of destination types. Although not all world cities are immigrant gateways, many are. 相似文献
