Recent work in geography has focused attention on the imbrication of landscape and literature. A dominant thread of these 'fictive geographies' has been a concern with how imagined landscapes contribute to the constitution of self. Informed especially by post-structuralism and post-colonialism, geographers have recently provided critical readings of novels, short stories and essays. In this paper I provide a reading of George Orwell's essay 'Shooting an elephant'. The writings of Orwell reveal a long-standing engagement with issues of humanity and subjectivity, and I contend that this essay, rather than a straightforward polemic against British imperialism, reveals a concern primarily with the constitution of self within a colonial landscape. Orwell's essay thus provides insight into the processes whereby human subjectivities interact with space and structures. 相似文献

Review of and prospects for China’s human and economic geography 总被引：1，自引：1，他引：0
The “High-Level Forum of the Development of China’s Human Geography Under the Background of Change” was held in Beijing on January 22-23, 2016. More than 30 professors attended this forum. At this conference, they discussed the major progress made towards developing China’s human geography, as well as the existing problems, limiting factors, opportunities, international collaborations, emerging directions, and prospects in the development of this discipline. In recent years human geography has boomed, generating many important opportunities for its development. Establishing an academic community for joint research on major research issues and collaborative innovation is a promising and important route to take. We should embrace both domestic and international characteristics, to promote China’s human geography onto the world stage. Meanwhile, the cultivation of various scholarly talents is also of great value to enrich and advance the discipline. 相似文献

The increasing quantities of solid waste and the high costs of its collection call for modifications of the collection routes in urban areas, in order to reduce the number of collecting teams and the distances travelled by them. Several mathematical models, aiming at the optimization of route length, are examined in this paper. It is suggested that the solutions derived from these models are only partial and that they cannot fully handle some of the constraints which the collection routing problem involves. The preferred method, therefore, is the heuristic model which is based on manual analysis of the routes system using a set of specified rules. This method is, then, used for an analysis and modification of the waste collection routes of Givatayim, Israel. Implementation of the proposed routes may save the town one out of six collection teams and would reduce the total distance travelled by some 18.7 per cent. 相似文献

Water resources occupy an important role in the bilateral negotiations of the Middle East peace process. This paper mentions the conflicting water plans for the utilization of the Jordan basin by Arabs and Israelis, and describes the issues that are to be handled in the process of peacemaking. It defines the water issues between Israel and each of its neighbouring entities: Jordan, the Palestinians, Syria and Lebanon, and reviews what has been addressed in the peace negotiations thus far. A more detailed review is made of the negotiation tracks where progress was made, and a less detailed review is made of the negotiations that settled the water dispute between Jordan and Israel. The paper alludes to the claims of water wars in the region and provides evidence that water has not been a catalyst for war in the Middle East. It also proposes some topics for research that can be of interest to alleviate water shortage. 相似文献

This essay introduces a collection of “think pieces”— conceptual, theoretical, editorial, normative essays on geography and race/racism. The collected essays follow from a National Science Foundation and Canadian Embassy – funded workshop on race and geography held in 1998. This introduction provides a brief background summary of the social and disciplinary context for the workshop and for scholarly work on race and geography, and a brief summary and thematic categorization of the individual essays gathered here. 相似文献

This paper investigates the conflict that arose as the result of opening a McDonald's restaurant adjacent to a national shrine in Israel. This conflict transformed Golani Junction, previously associated with the meanings assigned to the Golani memorial, into a contested place and a controversial issue. The paper outlines the conflict and the attempts to reach a compromise solution. The main argument is that the conflict reflects the notion prevalent among those dedicated to the memorial site and to the values it enshrines that the restaurant defies the sacred character of the place and marginalized the memorial in the local landscape. The conflict of meaning is also associated with McDonald's being construed as a prominent symbol of the alleged Americanization of Israeli society and culture. With this, the controversial character of the Golani Junction is also an aspect of a wider debate concerning cultural identity in Israel. Beyond the local context and specific issues involved, the controversies that transform the Golani Junction into a contested place demonstrate how conflicting interpretations of place and the politics of its meaning are formulated in terms of landscape features and architectural details. 相似文献

ABSTRACT. Understanding what the American landscape meant to J. B. Jackson requires an exploration of his background, education, and antagonism to the International Style. No full critique of modernism appears in Jackson's mature published work. However, knowledge that the first issues of Landscape magazine in 1951 and 1952 were the work of a single author leads to discovery of Jackson's pseudonyms, especially H. G. West, P. G. Anson, G. A. Feather, and A. W. Conway. This article examines Jackson's pseudonymous writings and links them to his well-known essays on the landscape: “The Westward-Moving House,” “Other-Directed Houses,” and “Southeast to Turkey.” 相似文献

DANIEL D. ARREOLA 《Geographical review》2010,100(3):291-294
Editors' note: This essay by Dan Arreola begins the second set of retrospective pieces commissioned to celebrate the centennial volume. Members of the Editorial Board responded to our request to prepare brief commentaries on landmark Geographical Review articles that were influential in their professional careers. Although many other articles touched the minds of emerging scholars, this small sampling covers a fairly wide swath of the fabric of American geography. It also reminds us that each future article has the potential to have a similar enduring value and help open new intellectual vistas. In addition to Arrreola's piece, the short essays include the musings of Barry Keim, Susan Walcott, Larry Ford, and Risa Palm. 相似文献

This article explores the use of visual research methodologies for understanding the everyday political desires and behavior of individuals. Its goal is to extend conversations in geography about the use of visual methods for interpreting the relationships between society and space, specifically the ways in which photovoice techniques can help geographers better understand the ways in which intergenerational emplaced memories motivate and shape contemporary political action. Using an urban community in Costa Rica built through hybrid housing–antiviolence movements in the 1980s and 1990s as a case study, this article illustrates the material and metaphorical pathways that participants trace between historical social movements and contemporary social issues through their photo essays. Participant images are made in tandem with practices and movement in the present but recall and represent family histories and narratives of historical struggle in the past. Significantly, as savvy users embedded in visual worlds, participants use these moments of intersection between past and present to mobilize political arguments about value and justice in their community. In this way, visual methods reveal the political mundane: how individuals shape their political opinions through conversation between contemporary embodiment and experiences with social issues and family histories of social movement participation. Key Words: photovoice, urban social movements, visual research methods. 相似文献

电离层时延为GPS测量中最棘手、最严重的误差源,而极区结构复杂波动较大,电离层延迟极大影响了GPS测量精度,故在极区选取一个简单有效的电离层模型极为重要。将GPS及BDS采用的不同Klobuchar模型以及Ne Quick模型计算的极区总电子含量,以欧洲定轨中心提供的GIM模型电离层产品作为参考标准,研究三种广播电离层模型在北极地区的均方根和模型改正率。选取了2009—2013年共计5年的时间数据进行分析。结果表明,纬度在57.5°以上地区电离层改正GPS系统采用的Klobuchar模型基本不适用,但改正效果依然优于BDS,而Ne Quick模型改正效果弱于中低纬度,改正率整体在40%左右。 相似文献
