A Two-dimensional Heat Transfer Model for Atmosphere-land System in the Lake-dominated Alaskan Arctic

1 Introduction Shallow tundra lakes are one of the dominating landscape features in the Alaskan Arctic. They typically cover 20% of the total area of the North Slope of Alaska, and up to about 40% in the coastal plain [1,2]. Many lakes are, in their entirety or in part, shallower than the maximum annual ice thickness, consequently, some ice freezes completely to the lake bottom, nevertheless, large areas of water are deeper than the maximum ice thickness and the ice remains afloat througho…     

民族大迁移造就了北京城

民族大迁移 ,尤其是少数民族大迁移造就了北京城。辽、金、元、明、清五朝 ,均有民族大迁移。尤其是明清两朝 ,均将北京的前朝居民迁移出去 ,本族居民迁移进来。在今天的北京 ,辽代契丹人留下了天宁寺塔 ,金代女真人遗下金太液池的一汪清水 ,元代蒙古人的胡同和六海水系还在沿用 ,明代汉族工匠建成了宫殿、长城和十三陵 ,清代精美的皇家园林和王府建筑后人至今无法企及。

Social Capital, Resource Mobilization and Origins of the Civil Rights Movement

Abstract  This article critiques the contradictory claims of Robert Putnam and Aldon Morris in relation to the American civil rights movement. Putnam identifies the South as the American region most lacking in social capital, and argues more generally that the 1960s marked a watershed beyond which social capital in the United States declined in all regions. Morris identifies the indigenous resources of southern African American communities as fundamental to the civil rights movement's emergence in the late 1950s and sees the social networks and cultural assets of the African American church in particular as central to the movement. The article disputes Putnam's negative judgment of the South by highlighting the role played by various types of social capital in the movement's launch. It also challenges Morris's over-emphasis on the ability of charismatic, black church leadership to deliver mass support and re-affirms the role played by female lay figures, such as beauticians.     

我国企业学习取向的初步研究

组织学习取向的研究有助于理解和改善组织学习过程,从而提升组织学习能力。实证研究得出我国企业有五个学习取向:知识来源、学习效果、学习幅度、学习投入、传播形式。我国企业在各个学习取向上都不太极端,都采取比较折衷的学习方式;但是也存在着比较偏重于内部开发知识、渐进式的学习取向、侧重群体学习的特点。我国企业学习风格可以称之为不断改良型和实践共同体型(community of practice:即非正式的、集体学习实践)。
