1复杂系统、知识管理与组织学习过程动态模型研究显示文摘知识经济时代的组织是一个具有无尺度网络结构的复杂系统。知识管理是知识经济时代的必然要求。组织学习作为组织获取核心竞争力和可持续发展能力的重要手段,是一个动态的过程。本文在系统回顾相关研究成果的基础上,从复杂系统的视角对知识经济时代复杂环境下的组织学习动态复杂过程进行了系统的模型整合和创新,并对构建学习型组织可能遇到的障碍进行了一系列对策分析。戴万稳 赵曙明 蒋建武 Steve F Foster 2006中国软科学2006,,6:25
2Probiotic metabolites from Bacillus coagulans GanedenBC30^(TM) support maturation of antigen-presenting cells in vitro显示文摘AIM:To study the effects of probiotic metabolites on maturation stage of antigen-presenting immune cells.METHODS:Ganeden Bacillus coagulans 30(GBC30) bacterial cultures in log phase were used to isolate the secreted metabolite(MET) fraction.A second fraction was made to generate a crude cell-wall-enriched fraction,by centrifugation and lysis,followed by washing.A preparation of MET was subjected to size exclusion centrifugation,generating three fractions:< 3 kDa,3-30 kDa,and 30-200 kDa and activities were tested in comparison to crude MET and cell wall in primary cultures of human peripheral blood mononuclear cell(PBMC) as a source of antigen-presenting mononuclear phagocytes.The maturation status of mononuclear phagocytes was evaluated by staining with monoclonal antibodies towards CD14,CD16,CD80 and CD86 and analyzed by flow cytometry.RESULTS:Treatment of PBMC with MET supported maturation of mononuclear phagocytes toward both macrophage and dendritic cell phenotypes.The biological activity unique to the metabolites included a reduction of CD14+ CD16+ pro-inflammatory cells,and this property was associated with the high molecular weight metabolite fraction.Changes were also seen for the dendritic cell maturation markers CD80 and CD86.On CD14dim cells,an increase in both CD80 and CD86 expression was seen,in contrast to a selective increase in CD86 expression on CD14bright cells.The co-expression of CD80 and CD86 indicates effective antigen presentation to T cells and support of T helper cell differentiation.The selective expression of CD86 in the absence of CD80 points to a role in generating T regulatory cells.CONCLUSION:The data show that a primary mechanism of action of GBC30 metabolites involves support of more mature phenotypes of antigen-presenting cells,important for immunological decision-making.Kathleen F Benson Kimberlee A Redman Steve G Carter David Keller Sean Farmer John R Endres Gitte S Jensen 2012World Journal of Gastroenterology2012,18,16:8
3复杂系统视角下的组织学习动态过程研究显示文摘组织是一个具有无尺度网络结构的复杂系统。组织学习作为组织获取核心竞争力和可持续发展能力的重要手段,是一个动态的过程:从组织学习发生的载体来看,主要有个人、团队和组织等三个层次;就组织学习发生的方式来看,包括单环学习、双环学习和三环学习等三种模式;而从组织学习过程本身来看,则分为直觉感知、解释说明、归纳整合和制度化等四个子过程。本文在系统回顾相关研究成果的基础上,从复杂系统的角度对组织学习过程进行了系统的模型整合和创新,对复杂系统环境下如何构建学习型组织的可能遇到的障碍进行了一系列的分析。戴万稳 赵曙明 Steve F Foster 2006科学学研究2006,24,S1:6
4运用卫星数据和来自国家森林清查的野外数据进行全国森林变量估计显示文摘瑞典约有55%的土地面积被森林所覆盖。目前,瑞典的森林覆盖没有统一的和地理学上明晰的描述。现存的独立性数据源是Landsat TM和SPOT HRV卫星数据、地图蒙片(map mask)和森林清查样地。它们在一起,使森林变量(如材积和林分年龄)的计算机估计成为可能。这些估计的精确度在像素水平上是低的,但在林分水平上较高。在规划木材资源应如何加以利用或出于监测目的时,这类基于栅格的森林数据对政府来说是有帮助的。本文描述了以有效成本建立森林变量估计全国数据库的生成流程。我们在林分水平上评价了瑞典西南部某地森林变量估计的精确度。结果表明,总材积估计的整体均方根误差为33%,年龄估计的整体均方根误差为23%。Heather Reese Mats Nilsson Tina Granqvist Pahlén Olle Hagner Steve Joyce Ulf Tingelf Mikael Egberth Hkan Olsson 王胜 2003AMBIO-人类环境杂志2003,32,8:4
