组织行为模式演进模型的构建及其分析

文章基于社会心理学家放宽对个体追求效用最大化假设的模型和观点，将组织中个体间相互影响力的差异性引入模型，并就模型中关键因素的多种变化情况对模型的影响进行了模拟分析。发现组织中个体间影响力差异性大小、相互间作用频率等因素对组织行为模式的演进具有重要的影响：     

Pattem and mechanism of urban spatial growth in Nanjing City, 1979-2007

Urban spatial growth has become a hot topic of geographic science and urban research. Exploring the patterns and mechanisms of urban growth is the prerequisite to understand the urbanization process of China. The paper provides a spatial analysis method of using Remote Sensing （RS） and Geographic Information System （GIS）. and presents major patterns and mechanisms of urban spatial growth during the period from 1979 to 2007 in Nanjing City. Firstly, the paper introohwes the data, study area and methodology of the research. Then. the patterns of urban spatial growth are identified Subsequently, the main mechanisms of urban spatial growth are analyzed Finally some conclusions are drawn definitely. The features of urban spatial growth in Nanjing are as follows： during 1979-1988, urban spatial growth of each district was stow. and the inner growth was in excess of suburban growth; during the period of 1988-2000. urban growth of suburban was in excess of inner city. the most insensitive growth appeared in the southeast, and the growth of each aspect was relatively insensitive expect ecst and west; during the period of 2000-2007, urban growth of suburban was violent, the most insensitive growth appeared in the southeast. and the urban growth of each direction was insensitive except the west. The mechanisms of urban spatial growth are complex, the main ones of which are social and economic development. Besides. the guiding of urban planning and influence of urban spatial structure are quite obvious.     

基于VC视角中国企业盈利新模式:"主业+基金"

“主业＋基金”将是中国企业发展的新的盈利模式。过去企业家是卖产品赚钱,而从事VC的投资家则是靠卖企业赚钱。投资家比喻说,主业是养儿子,做好主业是为了企业的百年基业,多余的钱过去往往是搞失败的多元化,今后将会投资基金,基金是养猪,养肥了再卖掉。本文介绍了VC在美国的演变过程,以及如何为国有企业改制提供增值服务,最后分析了VC涉及的几个具体问题。     

Adventure tourism products: Price, duration, size, skill, remoteness

To test whether commercial tourism products in different adventure activity sectors have different functional characteristics, I took part in tours offered by 75 operators worldwide and analysed price per person per day, duration, prior skill requirements, remoteness, group size and client-to-guide ratios. There is an enormous range of variation. Some activities overlap but some are clearly distinguishable, on commercial as well as operational criteria. Products can be arranged on a scale from low volume, high difficulty, high price to high volume, low difficulty and low price. There are recognisable signatures for some subsectors, but not all.
