City senses: On the radical possibilities of pragmatism in geography     

Gary Bridge 《Geoforum》2008,39(4):1570-1584

This paper explores the radical possibilities of pragmatism for geography using the illustration of arguments concerning a renewed (urban) public realm through the exchange of validity claims in communication. Pressing further the pragmatist possibilities of Habermas’s idea of communicative action it draws on John Dewey’s work, and a range of contemporary pragmatist philosophers, to consider human communicability in its widest sense. This is then explored using an example of the spatiality and performativity of body-minds in a range of communicative spaces of the city. Then the paper moves on to consider the radical implications of pragmatism for geography in general in terms of body-mind/environment relations; a transactional view of space; experience, rationality and radical democracy.  相似文献

Identifying China’s leading world city: a network approach   总被引：3，自引：0，他引：3  

Xiulian Ma  Michael F. Timberlake 《GeoJournal》2008,71(1):19-35

This paper reports our research on China’s world cities. Formal network analysis of air passenger linkages for recent years among China’s most populous cities and among many of the world’s largest cities allows us to identify the country’s leading world city from among the leading Mainland candidates, Beijing, Shanghai and Guangzhou. We theorize our findings about China’s world cities in relation to both global forces (and China’s increasing entanglement with them) and the policies and actions of the national state. We examine the national and global urban network through a longitudinal, two-level analysis of airline passenger travel for four time points between about 1990 and 2005. We show that Beijing was China’s leading world city at the beginning of the time period, a status it lost nationally in as early as 1995, and then globally 10 years later. On the other hand Shanghai became China’s leading world city, and it acquired this status first nationally in 2000, and then globally in 2005. The changing status of the Chinese capital corresponds to the country’s increasing involvement with the capitalist world economy. Shanghai’s ascendance as the leading world city in China may indicate that global forces have come to play an increasingly important role relative to that of the developmental state.

强降雨条件下土质边坡瞬态稳定性分析   总被引：9，自引：1，他引：8  

吴长富  朱向荣  尹小涛  刘雪梅 《岩土力学》2008,29(2):386-391

基于实际降雨气象资料,设计了单峰降雨和8个不同时间间隔的双峰降雨计算方案,利用非饱和土力学理论,对边坡的瞬态稳定性进行了计算和分析,研究了水分在坡体内的运移对边坡稳定性的时间空间影响效应,同时考察了降雨入渗造成的土性渗透特性的改变。分析发现：一次降雨的影响历时约12 d,降雨后约0.5 d该类土质边坡最危险;不同时间间隔的两次降雨对边坡稳定的影响比单峰降雨的最小安全系数滞后约0.3 d～0.8 d,影响历时基本保持不变;土体物理力学性质、边坡最危险滑动面及其对应的安全系数随水分在坡体内渗透运移而变化。  相似文献

广州在沿海开放城市的旅游形象定位研究     

徐君亮 《海岸工程》1999,18(2):18-22

根据国际形象设计发展趋势,提出城市旅游形象设计应有３个层次：一是城市旅游整体形象;二是城市旅游吸引物的特色形象;三是旅游企业形象。根据Ｊｅｎｓｅｎ－Ｖｅｒｂｅｋｅ都市旅游产品界定模式,结合广州实际,分析了广州的旅游吸引物,将广州旅游形象定位为（１）商都旅游,包括购物,美食、商务旅游和现代化城市景观的游览;（２）近现代史迹旅游,包括古代史迹和建筑艺术的观赏,其形象口号为“两个中心”,即商贸中心和近现  相似文献
