Chronic kidney disease (CKD) is important in the fields of public health and health geography because of its heavy burden on the health system and high cost of treatment in its advanced stages. The causes of CKD are associated with diabetes and hypertension, but in some parts of the world, the disease occurs in the absence of these factors. Researchers identify this condition as CKD of “unknown” causes (CKDu). CKDu is a multi‐factored health problem and one suspected causal factor is contaminated drinking water. The disease occurs globally but is found in particularly high concentrations among people of certain ethnic and disadvantaged social groups living in very different locations around the world. CKD has become endemic in Western Australia where hospital admissions for Aboriginal people requiring renal dialysis or treatment for diabetes are much higher than for the general population. The possible proportions of CKDu cases among the CKD patients are unknown. This study examines the drinking water quality among communities such as these. Water chemistry analysis in these areas indicates that the nitrate and uranium content greatly exceed officially recommended levels. Most of these communities rely on raw groundwater to supply their domestic needs, and it is very likely that the people are unwittingly ingesting high levels of nitrates and uranium, probably including uranyl nitrates. Very few such remote communities have access to treated drinking water, and cost‐effective water treatment systems are required to provide potable water at the local scale. 相似文献

Christine Stansell 《Gender & history》1999,11(3):419-432
The political use of Woman as a universal category, transcending social divisions, has fallen into disrepute. Yet it is necessary, in looking at gender history, to understand not just its obfuscations but its sources and political effects. The essay proposes an intellectual and political history of the uses of the term Woman and a social history of the heterogeneous mixtures of women from different social groups who seized the term and gave it force. Discussing recent scholarship on white and Afro-American women, Stansell argues for the importance of moments of extravagant universalising to the history of women in politics. 相似文献

Constitutional reforms are taking place in Scotland, Wales and Northern Ireland. These offer the opportunity to bring about a more effective policy framework for a range of policy areas including land use planning. In Scotland, the introduction of the Scottish Parliament in 1999 could allow the improvement of spatial planning policy and practice in a variety of ways, including bringing a more strategic approach at regional level, introducing a national plan and ensuring greater links with innovative community planning exercises. Such improvements could ensure a more sustainable environment as well as a more inclusive society and could offer lessons for similar practice in other contexts. 相似文献

This article explores the dominant explanations of the failure of forest management in Indonesia within the public discourse of the late New Order period. Drawing on a review of salient literature and relevant case studies, the major part of the article discusses the underlying historical, institutional and political causes of the failure of the state property regime. By taking a narrow view of the issues, public discourse during the New Order (1966–98) avoided discussion of the structure of property relations and the power relations that supported them. However, the forest fires of 1997–8 and the ensuing ecological crisis have revealed that the forest policy that allocated property rights over vast areas of the nation’s forests to well-connected conglomerates and politico-business families was inequitable and lacked legitimacy. While new legislative initiatives open up possibilities for co-management, the reforms so far barely engage with the underlying structure of property rights. These issues will need to be more thoroughly addressed if Indonesia is to tackle the bitter legacy of the Suharto period. 相似文献

Temporal changes in average stature are often used as a measure of a past population's adaptation, or lack of it. Traditionally, stature estimates have been calculated using formulae derived from limb proportions of cadavers. However, many authors have noted the problem of regional or population variation in body proportions of such reconstructed ratios. Before differences in stature can be attributed to environmental adaptation, ‘ethnic’ or population differences in limb ratios must be taken into account. The present paper calculates the stature of a medieval Norwegian skeletal sample using archaeological plan femur length and dry bone femur length. The author presents a variety of formulae and compares the stature derived from these calculations to the stature derived from archaeological plans. The Trondheim statures are then compared to stature reconstructions of other contemporary populations. 相似文献

The effects of heat on the stable carbon and nitrogen isotopic ratios of collagen in bone were studied. Boiling or roasting did not change the δ13C and δ13N values by more than 1‰. More extreme heating, such as might occur if bones were burned or a body cremated, shifted δ13C and δ15N values by as much as 5 and 4‰ respectively. These large shifts were accompanied by changes in the atomic carbon-to-nitrogen ratios of the collagen. These results indicate that collagen samples extracted from prehistoric bones which display anomalous atomic carbon-to-nitrogen ratios may have been subjected to heating extreme enough to have altered their and/or ratios and therefore should not be used for dietary reconstruction. 相似文献

Abstract. Filipino women participated actively in the Philippine Revolution (1896–1902), performing a wide range of tasks essential to sustaining the revolutionary challenge against Spanish and American imperialism. Though largely omitted from mainstream histories of the nationalist revolution, women's involvement has been recorded in several marginalised texts. However, these texts have invariably used a limiting format based on presenting biographies of outstanding women. This article suggests an alternative approach, by situating the history of revolutionary Filipino women within a comparative framework. The article outlines key ideas of feminist writers who have analysed women's participation in nationalist struggles from an international perspective. Drawing on these ideas, some new approaches to women in the Philippine Revolution are suggested. 相似文献

Recent Research in Paleoethnobotany 总被引:1,自引:0,他引:1
Christine A. Hastorf 《Journal of Archaeological Research》1999,7(1):55-103
This article discusses paleoethnobotanical research and results presented in the recent literature. Although archaeobotany
is a fairly recent addition to the study of the past, it now encompasses a diverse range of techniques, analyses, and new
results. Issues that are prominent in this archaeological subdiscipline include the origins of agriculture, resource use,
environmental reconstruction, anthropogenic environmental change, political-economic change, plant cultivation and crop production,
plant processing, consumption (diet), and site deposition. Some of the plant identification methods for macrobotanical remains
include morphology using light microscopes, histology with the scanning electron microscope, and statistics. The study of
microbotanical remains has expanded greatly and now includes pollen, phytolith, chemical, and molecular analyses. 相似文献
