Experiential Learning,Spatial Practice,and Critical Urban Geographies

Abstract

Experiential learning pedagogies are being adopted across undergraduate education and touted as an effective strategy for enhancing student learning. This paper develops an explanation for how and why such pedagogies can foster students' critical thinking and learning. Drawing on data collected from first-year students in “field based” urban geography courses at an urban university, I show how students' existing knowledge of urban spaces and specific parts of the city is constructed from a variety of sources and experiences, and can be incorporated in experiential learning activities in ways that foster critical learning. Such an approach is crucial to creating learning environments in higher education that include a greater diversity of student identities and life experiences.

海城大震对我们预测思维的启示

1975年海城大震表现出的现象启发我们进行了不少地震预测模型和预测指标的研究,本文对组合模式的前兆时空分布、垂直运动在发震中的作用、调制模式以及穴位理论等作了概括介绍。     

ON THE MAINTENANCE OF BLOCKING ANTICYCLONES OF NORTHERN HEMISPHERE-PARTⅠ:QUASI-GEOSTROPHIC POTENTIAL VORTICITY ANALYSIS

Four observed blocking anticyclones in different regions of the Northern Hemisphere are investigated.Analyses show that there exist distinct differences in the maintenance of the time-mean quasi-geostrophic potential vorticity(PV) low in 300 hPa within blocking areas.In two Pacific blocking cases,the PV advection by time-mean flow tends to flow the PV low to northwestern part of the blocking highs,and thus is beneficial to the maintenance of the blockings'strength.The transfer by transient eddies acts to balance the effect of the time-mean flow.In the Atlantic and Alaska blocking cases,however,the advection of mean flow tends to flow the PV low eastward.The PV transfer by transient eddies acts to flow potential vorticity low to the western part of the blocking ridges and also to balance the time-mean flow's effect.Thus,in the latter two cases,it is the transfer by the transient eddies that acts to maintain the blockings.     

适应市场发展动向,引进先进技术装备,提高工程施工队伍应变能力

建筑基础工程市场不断发展，技术装备随之也不断更新、改造。地矿部在工程装备的更新改造上有着周密的部署，因而工程施工单位应遵循这一部署，适当引进先进的工程技术装备，作为“龙头”带动常规的设备投放市场、改善、扩展基础工程市场的活动空间，提高工程市场的占有率和设备的开动率，使工程勘察这个支柱性产业获取更高的经济效益。
