高校及科研院所机构协同创新绩效的影响因素研究——基于社会网络的视角     

常路  汪旭立  符正平 《科技管理研究》2019,39(14)

本文以联盟管理、社会网络理论为基础，以参与“2011计划”协同创新中心的合作单位为研究对象，从组织声誉、联盟经验和网络中心性三个维度，对高校、科研院所的产学研合作协同创新绩效的影响因素进行了研究。在对国内外相关理论研究进行梳理与回顾的基础上，提出研究问题并建立实证研究模型，并利用二手数据进行分析验证。最终得到以下结论：（1）高校及科研院所的组织声誉与协同创新绩效之间的关系不显著；（2）高校及科研院所的联盟经验与协同创新绩效之间存在显著的正相关关系；（3）高校及科研院所在协同创新合作网络中所处位置的中心性对其联盟经验与协同创新绩效之间的关系起部分中介作用；（4）政府合作对高校及科研院所在协同创新合作网络中所处位置的中心性与其创新绩效之间关系的调节作用不显著。  相似文献   

Dependency, resource depth, and supplier performance during industry downturn     

Tomi Laamanen 《Research Policy》2005,34(2):125-140

This paper examines the effects of supplier dependency and resource depth on the performance of telecommunications suppliers during an industry downturn. It is shown that the R&D carried out independently by a supplier relates positively to the technological depth of the supplier's offering, which is further positively linked to performance. In contrast, the dependency of a supplier shows a negative curvilinear relationship (inverted U) to performance. The research policy implication of our finding is that, in addition to collaborative R&D, a supplier should also be encouraged to initiate its own independent R&D in order to reduce the potential distress on the business during an industry downturn.  相似文献   

Socially shared metacognition of dyads of pupils in collaborative mathematical problem-solving processes     

Tuike Iiskala  Marja Vauras Erno Lehtinen  Pekka Salonen 《Learning and Instruction》2011,21(3):379-393

This study investigated how metacognition appears as a socially shared phenomenon within collaborative mathematical word-problem solving processes of dyads of high-achieving pupils. Four dyads solved problems of different difficulty levels. The pupils were 10 years old. The problem-solving activities were videotaped and transcribed in terms of verbal and nonverbal behaviours as well as of turns taken in communication (N = 14 675). Episodes of socially shared metacognition were identified and their function and focus analysed. There were significantly more and longer episodes of socially shared metacognition in difficult as compared to moderately difficult and easy problems. Their function was to facilitate or inhibit activities and their focus was on the situation model of the problem or on mathematical operations. Metacognitive experiences were found to trigger socially shared metacognition.  相似文献

合作信息查寻与检索的知识共享模型   总被引：1，自引：0，他引：1  

韩毅  李鹏 《中国图书馆学报》2011,37(6):43-49

合作信息查寻与检索（CIS&R）是一种社会群体性的认知行为,其最终目标是满足用户理解和利用信息的需求,提高和完善用户的知识结构。在文献调研的基础上总结合作信息查寻与检索框架模型的两种构建方式：基于传统模型的扩展改善与基于特定领域的概括归纳。讨论该领域的知识共享研究现状,提出CIS&R的本质是知识共享过程。从情境及任务的视角出发,在社会认知观的指导下构建CIS&R知识共享模型,讨论该模型的4个主要构成要素：共享主体、共享客体、共享行为及共享情境。指出所构模型的局限性,展望基于该模型的进一步研究内容。图2。参考文献18。  相似文献   

互联网用户协同创作与内容共享的活动系统研究   总被引：1，自引：0，他引：1  

张薇薇  王昊  朱晓东 《中国图书馆学报》2011,37(4)

基于内容开放共享的互联网用户协同创作活动采取异步异地的工作模式、共享控制的管理模式以及实时反馈的协作策略。采用活动理论的研究框架和分析方法构建了互联网用户协同创作与内容共享的活动系统模型,并逐步分析其活动要素、子系统以及活动结构。定义并描述了主体、客体、社群三个核心要素,工具、规则、角色三个媒介要素,以及生产、消费、协作和交流四个子系统,将活动过程分解为消费、生产、反馈与协作、冲突与协调四个阶段并深入分析了各阶段的结构特点。基于动态流程分析,描述了社群结构中用户的角色分化现象,并推演出被动用户、外围贡献者、核心贡献者、异常用户、社群参与者五种角色类型。图3。表2。参考文献29。  相似文献   

Study of resonance-cone propagation in truncated hyperbolic metamaterial grids using transmission-line matrix simulations     

Omar F. Siddiqui  George V. Eleftheriades 《Journal of The Franklin Institute》2011,348(7):1285-1297

In this paper, we utilize transmission-line matrix simulations to study the electromagnetic properties of hyperbolic metamaterial grids, which are synthesized by arranging unloaded transmission lines over electrical ground planes, such that the unit cells are rectangular in shape. The hyperbolic grids support Bragg and Hyperbolic resonant modes that have rectangular and hyperbolic dispersion surfaces, respectively. We demonstrate the formation of these resonant modes in the hyperbolic grids and their refraction, and spatial scanning properties via circuit simulations. The simulation results are compared with experimental results of a two-layer anisotropic hyperbolic metamaterial.  相似文献   

Enterprise Information Portals in support of business process, design teams and collaborative commerce performance     

Hsin Hsin Chang^{Author Vitae}  I. Chen WangAuthor Vitae 《International Journal of Information Management》2011,31(2):171-182

Enterprise Information Portals (EIPs) have been widely adopted as platforms for the integration of knowledge management and information technology (IT). This study has been conducted from the knowledge management perspective in order to examine the influence of EIPs on collaborative commerce in the automobile industry. This study explores the integration of internal and external business processes and the coordination of collaborative design teams. An initial qualitative investigation explores the practical applications of an EIP in an automobile company. A research model is then formulated and tested using a questionnaire survey of the R&D department of a motor company in Taiwan. The results of the data analysis reveal that presence of EIPs can help a company realize the benefits of c-commerce. EIPs also can improve collaborative commerce performance by promoting the degree of integration of the enterprise process and by strengthening the process innovation and communication of collaborative design teams. The results suggest that managers should reinforce important factors, including knowledge management tools, process integration, and the quality of design teams, in order to achieve success in collaborative commerce.  相似文献   

用户意图聚类的数字资源推荐方法     

周之诚 《情报理论与实践》2011,34(6)

综合用户背景与资源特点,基于用户的协同过滤更适合高校图书馆在信息推荐中的应用。对其由于馆藏数字资源空间增大而导致推荐系统性能下降以及数据稀疏性问题,提出一种用户意图聚类的方法。通过运用K—means算法,对资源类别的意图特征值相似用户进行聚类,来提高推荐的实时性,降低数据稀疏性对信息推荐造成的影响。实验结果表明,基于用户意图聚类的协同过滤算法能有效提高推荐质量。  相似文献   

教师桌面发布与共享实验教学软件的设计与实现     

姚玉姝  陈宏亮  李晓珊  张建春  狄国强 《科技广场》2011,(5)

程序设计、软件开发类的实验教学要求越来越高,教学环境一般在网络机房。而学生掌握着自用电脑的控制权,甚至可以随意上网,网络教学环境使学生的思想不容易集中于教学,导致效率不高,教学效果不好。教师桌面发布与共享使教师的电脑桌面在必要时取代学生电脑桌面,迫使学生集中于教学内容,减少了外界环境对学生的吸引。借助于网络控制,教师和学生还可以实现互动式的教学,方便教师演示操作,协助学生提升教学效果。  相似文献
