Some things do change: indigenous rights,geographers and geography in Australia     

Richard Howitt  Sue Jackson 《The Australian geographer》1998,29(2):155-173

Using a recent editorial comment in this journal as a focus, this paper reviews the extent to which geography has been implicated in the ‘colonial project’ in Australia. It argues that recent work amongst geographers involved with indigenous Australians reflects a commitment to transcend this colonial past. The paper calls for geographers to work toward a wide‐reaching decolonisation of the discipline, and to develop a better understanding of the contemporary legacies of geography's colonial past.  相似文献   

Geologic assessment of environmental impact in Lake Macatawa,Michigan     

John B. Anderson  Richard Wheeler  Charles P. Dunning  Sue Shepley  Marion Fowke 《Environmental Geology》1978,2(2):67-78

A historical record of the effects of human development upon Lake Macatawa is established using geologic criteria. Significant cultural events are recognized using the pollen record, particularly ambrosia/vesiculate pollen ratios, and occurrences of detrital and chemical contaminants within the more recent sedimentary column. Detrital contaminants include such things as cinder and ash from coal burning power plants and animal hair from early tanning operations. Trace metal contaminants, frequently associated with specific industrial events, are particularly useful in establishing a modern sedimentary chronology. The impact of human activity upon Lake Macatawa is measured using fossil diatoms. The advantage of this method of environmental impact assessment is that it provides a historical perspective in which changes within an environment are related to its natural conditions.  相似文献

Strategic coastal flood-risk management in practice: Actors’ perspectives on the integration of flood risk management in London and the Thames Estuary     

Loraine McFadden  Edmund Penning-Rowsell  Sue Tapsell 《Ocean & Coastal Management》2009,52(12):636-645

This paper examines constraints and enabling factors towards ‘integration’ as they are perceived by actors involved in an ongoing strategy development process. The paper examines stakeholder perspectives on current progress in coastal flood risk management in London and the Thames Estuary. The case-study suggests that important steps have been taken towards an integrated and adaptive strategy development process, particularly through the development of informal stakeholder networks. However, constraints in enabling learning within the strategy development process mean that practical pathways of integration in such a large, global-scale city remain challenging to identify and perhaps even more so to implement.  相似文献   

Efficacy of a multi-metric fish index as an analysis tool for the transitional fish component of the Water Framework Directive     

Coates S  Waugh A  Anwar A  Robson M 《Marine pollution bulletin》2007,55(1-6):225-240

The WFD has introduced an international commitment to assess the ecological status of transitional waters (TWs), within which fish communities are a key biological monitoring component. The Transitional Fish Classification Index (TFCI) outlined in this paper uses 10 ecological measures to analyse fish populations caught from various ecological niches using a variety of gear types within the Thames estuary. These reach and method-specific communities are then compared to a reference population created from a 'healthy' population from TWs of a similar type. The results indicate a progressive downstream increase the quality of fish communities, consistent with previous work; variation between methods can be accounted for by gear selectivity. Overall, the TFCI is an effective communication tool for converting ecological information into an easily understood format for managers, policy makers and the general public.  相似文献   

模拟CO_2埋藏的煤储层元素迁移实验研究     

刘长江  桑树勋  G.X.Wang  Sue Golding 《中国煤炭地质》2010,(1):20-23,26

采用高压超临界CO2地球化学反应器对CO2在煤储层中的地质埋藏进行模拟,利用电感耦合等离子体发射光谱仪(ICP-OES)以及电感耦合等离子体质谱(ICP-MS)分别对淋滤液和煤样中的10种微量元素进行测试,对煤中微量元素在CO2的地质埋藏过程中的迁移进行了实验研究。结果表明:在CO2的地质埋藏过程中对煤的有机组成和无机矿物等均具有改造作用,从而影响到煤中微量元素的赋存和迁移特征,Cr、Zn、Cu等元素迁移能力相对较强,而Co、Ba、V等元素相对较弱;元素迁移能力大小顺序为:CrZnCuNiCdMnCoBaV。  相似文献

Evolving Turbulence Realizations of Atmospheric Flow     

Sue Ellen Haupt  Andrew J. Annunzio  Kerrie J. Schmehl 《Boundary-Layer Meteorology》2013,149(2):197-217

A significant difference exists between estimates of contaminant atmospheric transport and dispersion calculated by an ensemble-averaged model and the turbulent details of any particular atmospheric transport and dispersion realization. In some cases, however, it is important to be able to make inferences of these realizations using ensemble-averaged models. It is possible to make such inferences if there are sensors in the field to report contaminant concentration observations. Any information determined about the atmospheric transport and dispersion realization can then be assimilated into a forecast model. This approach can enhance the accuracy of the atmospheric transport and dispersion forecast of a particular event. This work adopts that approach and reports on a genetic algorithm used to optimize the variational problem. Given contaminant sensor measurements and a transport and dispersion model, one can back-calculate unknown source and meteorological parameters. In this case, we demonstrate the dynamic recovery of unknown meteorological variables, including the transport variables that comprise the “outer variability” (wind speed and wind direction) and the dispersion variables that comprise the “inner variability” (contaminant spread). The optimization problem is set up in an Eulerian grid space, where the comparison of the concentration field variable between the predictions and the observations forms the cost function. The transport and dispersion parameters, which are determined from the optimization, are in Lagrangian space. This calculation is applied to continuous and instantaneous releases in a horizontally homogeneous wind field such as that observed during traditional transport and dispersion field experiments. The method proves to be successful at recovering the unknown transport and dispersion parameters for a numerical experiment.  相似文献   

Confronting the challenge of integrated assessment of climate adaptation: a conceptual framework     

Ian Sue Wing  Karen Fisher-Vanden 《Climatic change》2013,117(3):497-514

Key limitations of integrated assessment models (IAMs) are their highly stylized and aggregated representation of climate damages and associated economic responses, as well as the omission of specific investments related to climate change adaptation. This paper proposes a framework for modeling climate impacts and adaptation that clarifies the relevant research issues and provides a template for making improvements. We identify five desirable characteristics of an ideal integrated assessment modeling platform, which we elaborate into a conceptual model that distinguishes three different classes of adaptation-related activities. Based on these elements we specify an impacts- and adaptation-centric IAM, whose optimality conditions are used to highlight the types of functional relationships necessary for realistic representations of adaptation-related decisions, the specific mechanisms by which these responses can be incorporated into IAMs, and the ways in which the inclusion of adaptation is likely to affect the simulations’ results.  相似文献
