A Review of “Economic Geography: Places,Networks, and Flows”     

Max Lu 《The Professional geographer》2013,65(3):466-468

Landing a rescue helicopter in a wilderness environment, such as Yosemite National Park, requires suitable areas that are flat, devoid of tree canopy, and not within close proximity to other hazards. The objective of this study was to identify helicopter landing areas that are most likely to exist based on available geographic data using two GIScience methods. The first approach produced an expert model that was derived from predefined feature constraints based on existing knowledge of helicopter landing area requirements (weighted overlay algorithm). The second model is derived using a machine learning technique (maximum entropy algorithm, Maxent) that derives feature constraints from existing presence-only points; that is, geographic one-class data. Both models yielded similar output and successfully classified test coordinates, but Maxent was more efficient and required no user-defined weighting that is typically subject to human bias or disagreement. The pros and cons of each approach are discussed and the comparison reveals important considerations for a variety of future land suitability studies, including ecological niche modeling. The conclusion is that the two approaches complement each other. Overall, we produced an effective geographic information system product to support the identification of suitable landing areas in emergent rescue situations. To our knowledge, this is the first GIScience study focused on estimating the location of landing zones for a search-and-rescue application.  相似文献   

The Particularity of Global Places: Placemaking Practices in Los Angeles and Sydney     

《Urban geography》2013,34(2):92-119

What makes places different from one another in the context of globalization? An analysis of 17 emblematic practices in two global cities, Los Angeles and Sydney, provides the empirical basis for answering this question. Evidence from the built environment, the social geography, and the patterns of disorder in the inner cities of these two global places shows that these cities were more alike in the late 1960s than they are today. The differentiation of the two places has increased as the effects of globalization have become more pervasive. The evidence presented in this paper suggests that there is nothing inherent in contemporary globalization that requires global cities to have inner city slums, ghettoes, massive homelessness, residential disinvestment, White flight, relict or suboptimally-utilized brownfields, illegal prostitution, a war on drugs, public spaces awash with guns, and so forth. Places are viewed here as constellations of distinctive practices configured in particular geographical settings at the intersection of specific conjunctures of historical change. Places matter in the epoch of globalization as differentially embedded, bounded particularities consisting of a mixed assortment of human practices forming causally consequential fields of effects.  相似文献   

Economic globalization and regional disparities in the Philippines     

Anne Clausen 《Singapore journal of tropical geography》2010,31(3):299-316

This paper empirically tracks the Philippine (policy) path following the mantra of economic globalization over the past 25 years. Specifically, it investigates the resulting regional growth‐inequality relationships and development footprints accompanying the restructuring of political economy and livelihoods. The Philippine case thereby shows how globalization can simultaneously cause the selective dismantling of (economic) barriers and enhancement of mobility and growth, as well as a deterioration of socioeconomic inequalities in space and society. In an increasingly deregulated and contested environment these development divides do not just pose serious threats to regional balance and national cohesion but, ultimately, undermine state capacity to achieve avowed goals of inclusive growth, stability and equality for citizens.  相似文献

以国内出版的专著和重要学术期刊发表的学术论文为资料基础,运用文献计量学方法,对1978年改革开放30多年来中国城市地理的研究进展进行了总结。研究发现：中国城市地理研究总体上日益繁荣,研究内容不断拓展和深化,研究方法逐步走向“科学化”和“规范化”,研究的空间尺度总体上“由大向小”转变,研究视角向多样化转变;国家政策和城市热点问题对研究内容具有重要影响,西方理论和流派对研究视角具有重要影响;基础研究与应用研究并重是重要特色,城市化与城市体系是重要的研究主题。建议在未来的研究中培养全球化视野,批判性地引进西方理论,加强理论创新、科学规范、跨学科交叉与新方法引进。  相似文献   

Reflecting on Role Play in Geographic Education: The Case of the Banana War     

《The Journal of geography》2012,111(1):16-27

Abstract

Debates over the nature and extent of globalization raise many issues to be addressed in a geographic education. In this paper, I briefly review case method instruction and role-play as teaching strategies suitable for material on globalization and other geographic subject matter, and then sketch an overview of an undergraduate geography role-play that treats themes of globalization and agricultural trade. The role-play revolves around a real-world trade dispute, referred to as the Banana War, that was waged between the United States and the European Union during much of the 1990s over who could sell how many bananas to Europe. I conclude the paper by reflecting on the contributions of, limitations to and possibilities for case method instruction and role-play in geographic education.  相似文献   

Global Dimensions of U.S. Legal Services     

Barney Warf 《The Professional geographer》2001,53(3):398-406

The internationalization of the world's producer services has included the steady expansion of legal services across national borders. This article opens with an examination of the supply and demand factors that have driven this process, including the strategies and problems faced by law firms that operate internationally. It then offers an empirical examination of the distribution of overseas legal services offices of the 700 largest U.S. law firms, including their foreign markets and headquarters cities.  相似文献

Spatial Disparities in the Expansion of the Chinese Ethnoburb of Los Angeles     

Lin  Jan  Robinson  Paul 《GeoJournal》2005,64(1):51-61

Suburban Chinatowns are intriguing subjects for study and comparison. These ethnic suburbs, or ethnoburbs, have emerged to coexist or compete with the older downtown Chinatowns traditionally found in American central cities. Their growth since the 1960s challenges many traditional assumptions regarding the spatial and cultural assimilation of immigrants in U.S. society, namely that ethnicity would decline with the geographic and socioeconomic mobility of immigrants from the inner city into the suburbs. We examined recent growth trends in the Chinese ethnoburb of the San Gabriel Valley region of Greater Los Angeles, through analysis and mapping of U.S. Census data, and discovered ethnic persistence rather than spatial and cultural assimilation. We also discovered the ethnoburb is differentiated between a lower-class core and two middle-to-upper class fringe districts. Though there is some linguistic assimilation on the northwest fringe, the majority of the ethnoburban population continues to speak Chinese. Linguistic isolation is not a barrier to achieving a higher socioeconomic class position in the Chinese ethnoburb of Los Angeles. An earlier version of this paper was presented at the American Sociological Association Annual Meeting, San Francisco, California, August 2004.  相似文献   

GLOBALIZATION AND EXTERRITORIALITY IN METROPOLITAN CAIRO     

PETRA KUPPINGER 《Geographical review》2005,95(3):348-372

ABSTRACT. Rapid construction of new spaces like hotels, malls, private clubs, and gated communities in Greater Cairo, Egypt produces structures disconnected spatially and conceptually from most of the existing urban fabric. Their spatial concepts and practices, as well as architectural forms and expertise, are based largely on globally available models. Planning and construction are guided by the search for security in the face of real or imagined fear of the urban masses and political upheaval. Concrete walls, guarded entrances, and high‐tech security technology bear witness to these fears. Analysis of the Mena House Hotel, the Grand Egyptian Museum project, and the First Mall in Giza shows how these projects globalize Cairo and localize the global. Often these globalized spaces are remade by creating local and regional ties and design features that were not anticipated by the planners. Such changes shed light on underlying dynamics and contribute to a better understanding of in situ globalization. Whereas their physical features tend to accentuate their globalized nature, these spaces do not exist in isolation from their geographical and cultural contexts. Their everyday realities tell tales of reterritorialization that are frequently overlooked in scholarly debates.  相似文献
