A Norwegian geographer and Deputy Head of the International Northern Sea Route Programme (INSROP) Secretariat surveys past, present, and potential future Northern Sea Route (NSR) cargo flows. The route's economic potential and importance, both as an international transit route and as a transport corridor to and from the Russian Arctic regions, are discussed. An overview of the main NSR infrastructure components (icebreakers, ice-class cargo vessels, ports) also is made, with estimates of future capacity. Based on the survey of future cargo potential, future infrastructure requirements are calculated and compared with estimated capacity in order to identify possible future bottlenecks for NSR operations.

The paper discusses the absence of gender from the analysis and understanding of urban development as a result of dichotomies, implicit or explicit, in much of urban research: private space vs public space, home life vs politics, domestic labor vs paid employment, reproduction vs production. It is argued that urban analysis and theorizing have focused almost exclusively on the latter part of such dichotomies, the one associated with men and masculinity. This is an emphasis on and valuation of the adult male's activities and experiences of urban development and a corresponding devaluation of the activities and experiences of women — thereby reproducing gender hierarchies and ways of thinking about them. To consider these questions, a historically and geographically specific context of urban development is presented: the municipality of Helioupolis in the Greater Athens area (Greece). This study helps explain how the boundaries of divisions and dichotomies are transcended in women's everyday lives; how women (and men) are not exclusively identified with either part of dichotomies; but also how dichotomies are often intensified — sometimes by perceptions and practices of women themselves. 相似文献

In summer 1990, the Commission of the European Communities published a "Green Paper" on the urban environment as a first step toward establishing an integrated policy for European cities, focusing on the revaluing of public space whose degradation is considered a symptom of a deep-seated developmental and environmental crisis. This article addresses the questions raised by the Green Paper: the needs to which it responds, and the results to be expected; the extent to which the proposed themes cover a "full range of difficulties facing Europe's conurbations," given the diversity of urban space in the old continent. Finally, it considers the paper's relevance for Greek cities: this highlights the existence of non-discussed city typologies within the single European space, which means that the concept of the European city should be carefully re-examined and based on the social and cultural plurality and complexity of the European cities, rather than stressing the existence of a single city-type. The Green Paper, when seen not as a text of generalizing assumptions or an instrument for action, may very well act positively to open a debate that will reveal and answer the specificities and the problems of each city. 相似文献

“地方”概念对人文地理学各分支意义的辨识 总被引:1,自引:0,他引:1
地方是文化地理学的核心概念之一.当文化地理学与其他人文地理学分支交叉时, “地方”则为其他人文地理学分支提供了分析的基础.本文结合英美地理学刊物中若干涉及“地方”研究的文章,挖掘了地方的概念和内涵,以期对人文地理学诸分支提供学术支撑.本文的结论是:地方研究可支撑经济地理学文化转向和制度转向的研究;支撑区域地理学地方营销和旅游地理学旅游目的地营销的研究;支撑城市地理学公众参与式城市规划方案的制定;支撑政治地理学的选区策略制定.因此, “地方”作为文化地理学的核心概念,其存在意义是为其他学科提供学术营养,同时,文化地理学对地方的研究也可以使得文化地理学的社会应用能力更强. 相似文献
