上海世博交流影响力的网络模型     

周伟刚  王远平  徐迅  刘超 《襄樊学院学报》2011,32(5):11-14

基于上海世博会对世界人民之间交流的影响力评价问题,建立了以国家和上海世博会为结点的网络模型,定义了世博交流影响力和未与中国建交的国家参展的交流影响力.分析显示:世博交流影响力随各参展国的投入和参展国数目的增加而增大;没有世博结点的网络交流状态越好,上海世博会的影响力越小.最后,通过数值算例验证上述结论.  相似文献   

水电建设项目风险评价方法概述     

陆盛斌  张瀚  伍仪保 《延安教育学院学报》2011,25(2):103-105

水电建设项目受地质、地理位置,气候等一些自然或非自然因素的影响,不可避免地存在诸多风险因素,业界相继对风险识别、风险分析以及风险评价等做了深入研究,但鲜有人概括了水电建设项目前的常用的风险评价方法。通过对水电建设项目前存在的风险评价方法进行概括,在其中提出了一种新的改进的评价方法,并比较分析了各自的适用条件以及优缺点,能为水电建设项目合理选择使用评价方法提供了有效的参考依据,进而能使风险预测与客观实际相接近。  相似文献

Gender differences in performance in mathematics at the end of lower secondary school in Italy     

Mariagiulia Matteucci  Stefania Mignani 《Learning and individual differences》2011,21(5):543-548

The paper deals with the investigation of gender differences in performances in mathematics for Italian students at the end of lower secondary school. The study is based on a new large-scale assessment test developed and administered by the National Evaluation Institute for the School System. Given the evidence in the literature which favors males, performances of female and male students are compared using different approaches. Scores proposed by educational experts based on item subgroups were considered, while a model-based approach was used within item response theory. The results revealed a significant advantage to males in overall performance, while no meaningful differences were observed with respect to item domain and type. An interpretable item map was developed crossing expert opinions with IRT abilities, and plausible proficiency levels were defined. According to the map-based student classification, a relatively lower percentage of females fell into the highest proficiency groups with respect to males.  相似文献

Emerging Educational Institutional Decision-Making Matrix     

Kevin H. Ashford-Rowe Marnie Holt 《美中教育评论》2011,(3):317-322

The ＂emerging educational institutional decision-making matrix＂ is developed to allow educational institutions to adopt a rigorous and consistent methodology of determining which of the myriad of emerging educational technologies will be the most compelling for the institution, particularly ensuring that it is the educational or pedagogical but not the technological imperative that drives the technology integration agenda. The matrix is designed to be used after some initial research into an emerging technology. Once a technology is put through the matrix, a member of options are available： （1） shelving the technology; （2） putting the technology on hold and maintaining a watching brief until the technology matures in the market; and （3） researching the product further by conducting a trial or placing in testing sandpit. After further research, the technology can be tested as a pilot to determine how well or otherwise, the technology works within the institution. If an emerging technology has more than one product associated with it, a second and third step in the matrix has been developed, and the second step assigns a rating to each of the categories within the matrix. With many products containing similar features, a third step has been developed to compare products on a feature level.  相似文献
