LOCAL ECONOMIC IMPACTS OF NATURAL DISASTERS*

ABSTRACT This research uses time‐series analysis under a quasi‐experimental pair‐wise matching design to examine local economic impacts of the 1993 Midwest flood. The data support the concept of overall local economic resiliency to natural disasters. The flood's impacts on total employment were minimal. Although significant drops in personal income were observed in the year of the event, the long‐run effects seemed to be negligible. This study also finds that the flood's negative impacts on agriculture were significant and long lasting to some Midwestern communities. The findings are quite stable with respect to the number of controls selected for each treated unit.

吐峪沟石窟的新发现影响吐鲁番历史的佛教遗址

敦煌文书唐代《西州图经》曾经这样描述唐西州时期高昌的丁谷窟：“丁谷窟有寺一所,并有禅院一所。右在柳中界至北山二十五里丁谷中,西去州二十里。     

新中国成立初期浙江省嘉兴地区乡村小学教育探析

新中国成立初期,嘉兴地区的乡村小学教育在国家的大力扶持下有了较快的发展,呈现出社会主义的新特征。但在社会主义建设过程中,由于急于求成,不少小学亦出现了流生严重、校群关系紧张等不良现象。同时,因为中央政府注重将乡村小学教育和农村社会环境相结合,使得中央和地方政府能够及时发现并解决问题。这表明国家在乡村小学教育中扮演着非常重要的角色,必须充分意识到政策在实践中的有效性,才能更好地进行国家建设。     

Macro-Modeling of Reinforced Concrete Structural Walls: State-of-the-Art

During the past decades, various analytical macroscopic models of structural walls have been developed for simulating the seismic behavior of reinforced concrete (RC) walls. Due to the inherently complicated characteristics of RC walls, macroscopic models that can capture all the important response characteristics with good accuracy and applicability are very challenging to establish. A thorough review of the four main types of mathematical macro models of RC walls, i.e., the vertical-line-element-model, the 2-D shear panel element model, the equivalent truss model and the fiber-based model, is presented to discuss the methodology behind each model and examine the corresponding merits and disadvantages. Suggestions are also made for the further research of the macro modeling of structural walls.

Two new Middle Jurassic species of orthophlebiids (Insecta: Mecoptera) from Inner Mongolia,China

QIAO, X., SHIH, C.K. & REN, D., December 2012. Two new Middle Jurassic species of orthophlebiids (Insecta: Mecoptera) from Inner Mongolia, China. Alcheringa 36, 467–472. ISSN 0311-5518.

Two new species of the extinct family Orthophlebiidae, Orthophlebia nervulosa sp. nov. and Orthophlebia stigmosa sp. nov., are described and illustrated. These well-preserved specimens were collected from the Middle Jurassic Jiulongshan Formation near Daohugou Village, Inner Mongolia, China. Morphological characters shown in these well-preserved specimens highlight the diversity of orthophlebiids during the Middle Jurassic and provide data for future phylogenetic studies of orthophlebiids.     

旅游产品交换过程中的价格与价值关系探讨

旅游产品的随意涨价,让很多游客感到头痛和不爽,然而业界还在蠢蠢欲动,继续运筹涨价。旅游产品的价格问题实际上关系到一重大的理论问题:由什么来衡量旅游产品价值量。旅游产品在其实现过程中没有物质性的产品传递过程,因此用"商品的价值量取决于社会必要劳动时间,商品按照价值相等的原则互相交换。价格围绕价值上下波动",已经明显解释不通了。感受才是决定旅游产品是否有价值的关键因素。旅游过程中旅游者所获得的感受越深,旅游产品的价值越大,因此它遵循刘氏"发汗定律"。也就是感受的程度是决定价格高低的直接因素。但是感受是一种纯粹的主观心理体验,它是人类社会经济文化背景的直接反映,也是人类文明的区域再现。     

社区精英群的联合和行动——对梨园屯一段口述史料的解说

19世纪 60年代以后 ,直东交界一带社区精英权力的拓展遇到外国教会的挑战 ,士绅团首在管理社区事务和维护道德教化领域的自我保护倾向拉大了其同州县政权的距离 ,并为体制外的民间组织公开化提供了社区空间 ,导致基层体制内外的多种组织反击洋教的联合行动日渐武装化。世纪之交的外患内忧使社区自卫运动促进了社区精英跨区域的横向联合和对区域性的民间文化的再创造。这一过程中形成的民间文化的三个标帜将多中心、区域性的民众反洋教集团联结成义和团运动     

且末古城地望考

本对以往学术界在且末古城地望问题上的考察和研究进行了全面总结,指出了失败的原因,进而认为且末古城位于车尔臣古河床的东岸,距今来利勒克古城3日路程的地方;如果以此为圆心,以3日路程为半径,由南向北划圆,在与车尔臣古河床交会处找到且末古城的可能性较大。
