21世纪地震灾害的一些新特点

灾害定量化是地球科学、工程科学和社会经济科学的交叉领域。人口城市化是全球的发展趋势，特别在第三世界人口城市化的趋势越来越显著。和农村发生突发灾害农民可以很容易地进行自救和互救不同，城市居民对供水、供电、煤气、暖气、通讯和交通等基础设施有很大的依赖性，现代城市在抗御自然灾害方面，比过去任何时候都显得更加脆弱。通过统计，我们发现在灾害损失 L和表征社会财富的GDP之间存在着经验关系：L＝ a＋ b×GDP＋ c×GDP 2其中 a，b，c为正的常数。关系式表明，自然灾害造成的灾害增长要比GDP的增长要快。

Researching the South African tourism and development nexus

Under apartheid, tourism was essentially anti-developmental in focus and tourism research largely centred on the recreation of white South Africans. Since the 1994 democratic transition tourism has become recognised as an increasingly important sector for South Africa's economy and for achieving the government's goals for reconstruction and development. In this paper a review and critical analysis is presented of the changing directions and foci of tourism scholarship in South Africa. It is shown that South African scholars are beginning to respond to the challenges posed by tourism as a developmental focus. This revised version was published online in August 2006 with corrections to the Cover Date.

Mapping the Bonanza: Geographies of Mining Investment in an Era of Neoliberal Reform*

Geographic analyses of how national policies of economic liberalization influence global patterns of economic activity often draw their conclusions from studies of the paradigmatic sectors of manufacturing and, to a lesser extent, services. There is, by contrast, relatively little work examining how neoliberal policy reforms in the developing world may be driving changes in the geography of primary sector (i.e., extractive) activities at the global scale. This article presents and analyzes new data on direct investment in the international mining industry. It reports methods and results from a research project to systematically map and evaluate changes in the commodity mix and geographical spread of mining‐related investment in the world economy since 1990. It confirms and quantifies what was hitherto anecdotal evidence of a geographic shift in investment during the 1990s away from mature targets toward a small number of “rising stars” in the developing world, following the adoption in many countries of neoliberal economic policies from the mid‐1980s onward. However, the findings challenge conventional interpretations of this shift as an investment “bonanza” in the periphery and highlight how recent investment trends are highly specific in geographical scope, concentrated within a few commodities, and how the allocation of investment between established and emerging targets is variable over both time and space.
