Place Matters: Comparative International Perspectives on Feminist Geography*

Feminist geography is now widely practiced internationally, but its development is usually reviewed from a temporal rather than a spatial perspective. This article assesses the varying extent and nature of feminist geography across countries, attempting to interpret differences in terms of cultural contexts and disciplinary trends. It is intended to stimulate reflection and does not claim to offer definitive interpretations.     

Hydrologic and geochemical properties of the San Andreas fault at the Stone Canyon well

The Stone Canyon well penetrates 600 m of highly fractured and severely altered quartz diorite intimately associated with the creeping segment of the San Andreas fault of central California. Geophysical logs reveal a complex hydrology dominated by major fractures. Fluid pressure in some fractures is sufficient to prevent invasion of the formation by heavy drilling mud, implying pore pressures at least 10% higher than hydrostatic ones. At least three chemically distinct waters are encountered, including a chloride brine clearly segregated from the shallow, potable groundwater. Chemical alteration of the quartz diorite persists throughout the well, far below the depth where the water-rock reactions responsible for the ubiquitous chlorite and mixed-layer clays can be considered weathering. Whole-rock ¹⁸O analyses indicate significant interaction of the rocks with a low ¹⁸O fluid within some of the fractured and altered zones, whereas a deeper sample shows¹⁸O enrichment. High pore pressures encountered in Stone Canyon may be due to tectonic compression. Measurements of temporal variations in the pore pressure at the well may provide a means of predicting earthquakes along this segment of the San Andreas fault.     

CCSD HP-UHP变质岩石英脉和东海水晶中有机包裹体的发现及其意义

荧光显微镜下观察、激光拉曼和显微红外测试,首次在CCSDHP-UHP变质岩石英脉和东海水晶中发现了含有沥青和烃类的有机包裹体,进一步证实大别-苏鲁超高压变质带曾经历了快速的俯冲与折返过程,俯冲板块沉积物中的有机质未能充分地演化和成熟。俯冲板块在进变质过程中强烈脱水,释放出含烃流体,并被在板块抬升及其伴随的减压重结晶和退变质过程中形成的石英脉和水晶体所俘获。     

浅析矿产资源储量动态管理现状、存在问题及对策

矿产资源开采必须实行有偿取得,有偿出让的本质是出让矿产资源储量,矿产资源的开发利用都是围绕矿产资源储量,离开矿产资源储量,采矿权的有偿出让就无从谈起。介绍了当前储量动态管理现状,提示了存在的问题,并就如何加强对矿产资源储量监管提出了对策并进行了探讨。

Planning issues in the territorial integration of the Korean peninsula

The historic summit between the leaders of the two Koreas in June 2000 provided a new opportunity for inter-Korean dialogue. Despite many uncertainties regarding the form and substance of inter-Korean economic cooperation, Korean people believe that inter-Korean economic cooperation will expand and eventually lead to economic and territorial integration of the two Koreas. This essay discusses the progress and issues of inter-Korean economic cooperation including infrastructure development. In particular, the essay examines long-term planning issues surrounding the territorial integration of the Korean peninsula and their implications for balanced development. With the German case of economic integration as a point of reference, the essay points out a few strategic problems involved in inter-Korean economic cooperation and suggests an alternative strategy to achieve balanced development.     

Malaria and related environmental issues in India: a case study of Aligarh city

Malaria is one of the most widespread diseases in the world. Endemic malaria no longer occurs in many temperate zones as a result of social and economic improvement. At present malaria is the Third World's most dreaded killer. It kills over 1 million people and causes 300–500 million episodes of illness. In India, malaria-reported deaths have shown an upward trend. In 1955, a drive to eradicate malaria was launched in India. But after initial success it failed and malaria made a comeback. Malarial mosquitoes generally prefer unpolluted natural breeding sites but now they have adapted to the changed urban environment. In this paper, an attempt has been made to examine the occurrence of malaria and related environmental issues in a small town of India. Aligarh city, lying in the shadow of the country's capital New Delhi, was selected as a case study. Data were collected mainly from household surveys with the help of questionnaire interviews. About 2,185 households belonging to different income groups were sampled. The differences in the occurrence of malaria in the different income households (in 87% low, 69% lower-middle, 65% middle, 14% upper-middle, and 5% upper) suggest that most of these differences are related to the environmental conditions existing inside and outside their homes, such as poor drainage system, poor sullage disposal, open blocked drains, waterlogging and indoor water storage in open containers. Commitment both by the Government and local residents is needed to improve the environmental conditions and eradicate malaria.
