Integrative multiplicity through suburban realities: exploring diversity through public spaces in Scarborough     

Ranu Basu  Robert S. Fiedler 《Urban geography》2017,38(1):25-46

Questions of “integration” are normatively assumed to promote particular ideals of the multicultural city and lead to a “settlement” culture that bodes well with the hegemonic majority. This paper, however, questions the concept from an alternative perspective – that is, it aims to explore how “integration” is imagined and understood by displaced migrants through the contextual specificities of multiple and peripheral “public spaces” – defined in this paper as the everyday practices of integrative multiplicity. Exploring these questions in Scarborough, a post-war primarily ethno-racialized suburb of Toronto, the unique experiences of migrants, many who have faced histories of trauma and violence suggest that the settlement experience is not devoid of anxiety and pain. Memories of places and communities left behind, sometimes never to be returned to, harness a longing and deeper need for home-making often spilling into the public realm. Understanding public space and its inherent conceptual and political complexity as defined, used, and valued by recent migrants, allows integration to be understood through the dynamics of power relations. The findings reveal how recent migrants not only understand and use the city but also how they reflect upon and envision the city-building process, through their own individual subjectivities of inclusion/place-making and exclusion/displacement. Through such complex spaces of encounter, civic engagement and grounded experiences, the participants frame Scarborough in multiple and metaphorical forms: from a City of Refuge and Peace; City of Memory, Desire, and Imagination; City of Multifariousness; to a City of Civic Engagement and Fluid Resistance. This stands in stark contrast from how the city is framed in dominant discourse and the unsettling debates on how to reform it.  相似文献

黄河流域动力系统泥沙时序混沌特征分析——地理系统综合研究的一种尝试   总被引：2，自引：1，他引：2  

马建华  楚纯洁 《地理研究》2006,25(6):949-958

选取黄河头道拐、潼关、花园口和利津断面1952²000年的泥沙含量为时序,在G-P重构相空间的基础上,分别计算了各断面泥沙时序的关联维（D2）、K2熵和Hurst指数。结果表明,各断面的最小饱和镶嵌维（m）、D2和K2熵分别为5、3.24和0.13,说明黄河流域各级系统均具有混沌特征,并且从上游到下游混沌特性逐渐增强。随着混沌特性的增强其平均可预报时间下降,头道拐断面为8年,其余断面为3年。各断面Hurst指数均大于0.68,在可预报时间内,各断面泥沙时序具有持续性下降趋势,并用2001²004年实际数据得到了验证。文章还给出了黄河流域动力系统的一般形式,该系统至少需要8个状态变量,2个控制变量。  相似文献

Integrative assessment of hydrological, ecological, and economic systems for water resources management at river basin scale     

Xianglian Li  Xiusheng Yang  Qiong Gao  Yu Li  Suocheng Dong 《Frontiers of Earth Science》2009,3(2):198-207

This study presents a basin-scale integrative hydrological, ecological, and economic (HEE) modeling system, aimed at evaluating the impact of resources management, especially agricultural water resources management, on the sustainability of regional water resources. The hydrological model in the modeling system was adapted from SWAT, the Soil and Water Assessment Tool, to simulate the water balance in terms of soil moisture, evapotranspiration, and streamflow. An ecological model was integrated into the hydrological model to compute the ecosystem production of biomass production and yield for different land use types. The economic model estimated the monetary values of crop production and water productivity over irrigated areas. The modeling system was primarily integrated and run on a Windows platform and was able to produce simulation results at daily time steps with a spatial resolution of hydrological response unit (HRU). The modeling system was then calibrated over the period from 1983 to 1991 for the upper and middle parts of the Yellow River basin, China. Calibration results showed that the efficiencies of the modeling system in simulating monthly streamflow over 5 hydrological stations were from 0.54 to 0.68 with an average of 0.64, indicating an acceptable calibration. Preliminary simulation results from 1986 to 1995 revealed that water use in the study region has largely reduced the streamflow in many parts of the area except for that in the riverhead. Spatial distribution of biomass production, and crop yield showed a strong impact of irrigation on agricultural production. Water productivity over irrigated cropland ranged from 1 to 1640 USD/(ha·mm⁻¹), indicating a wide variation of the production conditions within the study region and a great potential in promoting water use efficiency in low water productivity areas. Generally, simulation results from this study indicated that the modeling system was capable of tracking the temporal and spatial variability of pertinent water balance variables, ecosystem dynamics, and regional economy, and provided a useful simulation tool in evaluating long-term water resources management strategies in a basin scale.  相似文献

提出以四库一体模式实现基于ARCGIS的地质灾害防治决策支持的思路,即以模型为主导,调用方法,提取相关数据计算,对模型进行求解;利用ES对系统判识进行匹配、分析,辅助专家进行决策;将专家决策结果作为知识源提取而存入知识库中.信息系统是整个系统的事务管理层,决策支持系统则是系统应用处理层,两者互为依托.信息系统是决策支持系统的信息源,决策支持系统所产生的结果进入信息系统并对其进行管理,当决策支持系统的模型、方法、知识运作成熟,数据结构化后,又将进入信息系统中,成为信息系统的组成部分.  相似文献
