基于多重螺旋协同创新理论的DEA评价模型——以皖江城市带为例

根据三螺旋模型的基本框架、产学研理论和系统动力学构建I-U-G-R-U多螺旋协同创新模型,基于该模型内嵌两阶段链DEA模型和多重螺旋协同创新评价指标体系,并以皖江城市带为例进行科技创新能力评价的实证分析。实证结果表明:I-U-G-R-U多螺旋协同创新模型的测度结果较好;皖江城市带存在显著的科技梯度现象,科技创新没能实现承续性以及存在各要素投入存在不合理等现象。从区域内科技创新来看,皖江城市带内部科技创新效率差异大;从分阶段科技创新来看,皖江城市带将科技创新成果转化为经济产出的效率明显高于将科技创新所需资源利用并转化为科技创新成果的效率。

Search on surfaces: Exploring the potential of interactive tabletops for collaborative search tasks

Collaborative information seeking often takes place in co-located settings; such opportunities may be planned (business colleagues meeting in a conference room or students working together in a library) or spontaneous (family members gathered in their living room or friends meeting at a café). Surface computing technologies (i.e., interactive tabletops) hold great potential for enhancing collaborative information seeking activities. Such devices provide engaging direct manipulation interactions, facilitate awareness of collaborators’ activities, and afford spatial organization of content. However, current tabletop technologies also present several challenges that creators of collaborative information seeking system must account for in their designs. In this article, we explore the design space for collaborative search systems on interactive tabletops, discussing the benefits and challenges of creating search applications for these devices. We discuss how features of our tabletop search prototypes TeamSearch, FourBySix Search, Cambiera, and WeSearch, illustrate different aspects of this design space.     

University teacher approaches to design and teaching and concepts of learning technologies

This study investigates the experience of teaching of 19 teachers who are teaching on university courses involving face-to-face and on-line learning. The teachers are asked about how they think about learning technologies and how they approach the design and teaching of their courses across these two contexts. Results show that there are qualitatively different ways of thinking about learning technologies that relate logically and positively to qualitatively different ways of designing and teaching using learning technologies. The results have implications for teachers and those interested in maximising the likelihood of learning for university students when teachers teach with learning technologies.
