We have made progress in medico-chemical geography as follows: the correlative law of organism with geochemical environment; the geochemico-ecological classification of chemical elements; the types of formative cause of biogeochemical provinces in China; the parabolic correlation between contents of iodine in drinking water and prevalence rate of endemic goiter; the discovery and proof of the low selenium zone in China; the successive discovery of endemic fluorosis of the types of pollution from burning coal, drinking high fluoride tea and high fluoride table salt from the year 1978; the study on chemical geography of schistosomiasis and the compilation of the Atlas of Endemic Diseases and Their Environments in the People's Republic of China. 相似文献

There are a number of factors involved in teaching quality. Among them teaching materials or textbooks are of primary importance, the presentation of which relies first of all on the viewpoint to structure the contents geographically. Whatever branch of geography you are teaching or in pursuit, geographical viewpoint is vitally important. This paper in discussing innovation of geographical education about these institutions with the course of regional physical geography as an example. The higher education of our discipline is in pressing need of innovation and thereby upgrading quality. 相似文献

A survey of members of the Association of American Geographers (AAG) in 1982 indicated that most were males, from middle class backgrounds, had attended public universities, held academic jobs, and had been born and educated in states bordering the Great Lakes plus California and Massachusetts. Information on characteristics and trends outlined in the study should be of value to the leadership of the AAG in making decisions relative to the future of the organization and the discipline. 相似文献

Abstract: The restricted influence of geographers in the policy arena has been the source of some angst. This paper reports on a new initiative at the University of Canterbury, which aims to strengthen geography's contribution to health policy debates in New Zealand. The GeoHealth Laboratory is a joint initiative between the Department of Geography and Public Health Intelligence group at the Ministry of Health that seeks to provide a pathway for the integration of health geography research into policy development. This new facility aligns the expertise in health geography, GIS and other spatial analytical methods with policy-relevant research priorities. An overview of the strategic aims of the GeoHealth Laboratory is provided along with some examples of recent research activities that are contributing to understandings of the health landscape in New Zealand. It is argued that such partnerships provide important opportunities for geographers to engage with policy-relevant issues. 相似文献

Land use change studies permeate the geographic literature. While these studies have helped researchers understand the dynamics and importance of such changes, they have less often taken a deeper historical approach in combination with their traditional strengths of geographic information analysis. In this study, we explore historical land use changes in one of South Africa's former bantustans, Lebowa, from 1963 to 2001. We argue that changes in land use arise from both current socioeconomic dynamics but also from historical precedent established by the apartheid regime. Our methods couple historical aerial photography to recent household surveys to elucidate the national, regional and local influences over land use change. We conducted extensive field research in the study site between 2003 and 2006. Our findings show a high degree of urbanization, a loss of grassland and agricultural land and a dramatic pattern of increasing spatial concentration near growth points. We outline three recommendations for policymakers planning post-apartheid rural spaces and conclude with future research needs. 相似文献

Feminist geography and political geography still represent two solitudes within the discipline. While increased traffic between these different parts of the discipline points to a degree of intellectual engagement, there remains a paucity of feminist thought in political geography. This article examines recent scholarship on feminist political geography, with a view to applying its insights to the struggles to protest and end political violence. The concept of feminist geopolitics is employed and recast, both as a bridging concept between feminist and political geography and as an analytical approach that has political valence in the context of the war in Iraq. Feminist geopolitics is revisited in this article, but remains a critical analytic in relation to body counts and other casualties in war zones. 相似文献
