0515号登陆台风"卡努"引发江苏暴雨过程的动力学诊断分析   总被引:3,自引:1,他引:3  
赵凯  孙燕  王山旗 《台湾海峡》2006,25(3):414-419
研究了0515号登陆台风“卡努(Khanun)”对江苏暴雨过程的影响.结果表明,此暴雨过程属主要由台风本身的气旋性涡旋所造成的区域性暴雨,位于台风移向的右前方.通过对物理量场诊断分析发现,暴雨强度的趋势与落区基本上能从水汽通量相对散度上反映出来,水汽通量相对散度越大,暴雨越强;暴雨区位于垂直上升运动区.  相似文献

This article explores the pedagogical implications of students' embodied and emotional reactions to difficult course material inside and outside of the classroom. Scholarship on teaching typically focuses on dimensions of students' cognitive engagement and development, yet geographical coursework often involves emotionally fraught topics: environmental cataclysm, poverty, inequality, oppression, (ill) health, etc. Instructors who anticipate their students' emotional experiences will be able to better engage with and use these experiences toward learning goals. Some topics may be most effectively taught through emotionally activated learning activities, prompting reflection on the role of visceral learning experiences in higher education.  相似文献

Over two decades after the scholarly interventions that coalesced into ‘critical GIS’ as a field within GIScience, critical GIS remains underdeveloped in conversations on teaching and learning. The literature on GIScience education has emphasized content more than pedagogies – what to teach versus how to teach to move students toward particular learning objectives. This emphasis is reflected in dominant curricular approaches to critical GIS, in which questions around the complicated origins and complicit social, political, and economic relationships of GIS are taken up as discrete topics, tacked onto instruction that otherwise prioritizes technical dimensions of GIScience. We argue that GIScience coursework must resist such modularization by approaching critical GIS not as a set of topics, but an orientation to GIS praxis that ‘does’ GIS from within a questioning stance, to ask how we know. We outline specific curricular shifts and teaching practices we have used to foster this orientation in GIS students, offering ways of continually engaging students in practicing this orientation as they learn strong technical GIScience content. Finally, we trace the successes, challenges, and tensions sparked by these critical GIS pedagogies, drawing on student evaluation comments from our courses and reflecting on broader implications for GIScience instructors and geography faculty.  相似文献

Ethnic segregation has most often been studied at the place of residence, segregation being defined on the basis of the relative presence of different groups within city neighbourhoods. It is increasingly recognized, however, that segregation occurs in different ways in different domains (such as the workplace, leisure, social media, etc.), the residential domain being just one of many in which segregation can occur. In this research note we present the domains approach to segregation and outline some its conceptual, methodological and empirical underpinnings and challenges.  相似文献

Examining women’s choices around paid work in south India, this article shows the need to pay greater attention to the sphere of reproduction, and in particular the way that women endeavour to fit their productive work around their reproductive roles and responsibilities. Focussing on the region of the Tiruppur garment cluster in Tamil Nadu, India, it outlines the opportunities available to rural women, shedding light first on women’s decisions whether to work or not, and second, on how women choose between particular types of work available to them. The article demonstrates the primacy of the reproductive economy in shaping women’s movements in and out of paid work, particularly the importance of stage in life course, household composition and patriarchal control to women’s decisions. Main findings of the article are that most women work, but their particular job choices reflect multiple social and reproductive constraints, while those who withdraw from work have been subjected to new expressions of patriarchy. The article advances understandings in feminist geographies of work by drawing on ethnographic insights to highlight the mutual embeddedness of the reproductive and productive economies.  相似文献
