智慧城市应急决策情报体系构建研究

情报在城市突发事件应急决策中发挥着重要作用,建立情报灵、判断准、反应快的城市突发事件情报支持体系,是城市智能化建设的重要模块,也是智慧城市公共安全与应急管理的必然要求。本研究从顶层设计入手,以应急情报流与业务流为线索,以情报体系有效运行为目标,探究智慧城市应急决策情报体系的构建问题。从人员要素、机构要素、技术要素、资源要素、制度要素与行为要素六个方面,厘清了智慧城市应急决策情报体系的框架内容。从组织体系、保障体系与运行机制三个层面系统探讨了智慧城市快速响应情报体系的协同运作模式。大数据时代,智慧应急的情报工程化与情报平行化是未来发展的方向。图6。参考文献40。     

面向决策的“城市病”诊治情报服务探索

[目的/意义]探究面向决策的“城市病”诊治情报服务模式有利于对“城市病”问题进行综合把脉,帮助城市管理者迅速找准病因、症结,从而提升社会治理效率。[方法/过程]在总结“城市病”诊治相关理论与实践现状的基础上,从宏观环境（信息环境）、中观资源（大数据战略）与用户需求（决策需求）3个层面归纳“城市病”诊治情报服务的推动力,探讨“城市病”诊治情报服务体系的组织架构以及运行机制,指出“城市病”诊治情报服务应是环环相扣、动态演进、递进循环的工程化流程。[结果/结论]情报服务的介入可以促使“城市病”诊治过程更为精细化、系统化与协同化,为政府城市管理与决策提供极为有益的信息决策参考。按照工程化情报服务思维,“城市病”诊治思路将从被动的“应对”向主动的“服务”转变。

Technology’s role in learning at a commuter campus: The student perspective

Patterns of technology ownership and usage, as well as skills with and preferences for various technologies, affect the college experience (Educause 2012). Students at a commuter campus of a large Midwestern public university were surveyed about technology and the learning process: 94% of the respondents believed that technology had the potential to benefit learning and 85% thought it was central to their academic success. Students credited technology-enhanced courses with increased and more effective communication with instructors, the ability to better manage course activities and expanded opportunities for practice and reinforcement. Students’ prior experiences with a course management system affected their perceptions of the role of technology and their subsequent beliefs about the benefits of its use in their university courses. Implications for administrators who make decisions about faculty development, student retention and funding for technology-enhanced course offerings are discussed.     

地籍测量综合实习中新技术应用研究

地籍测量成果一经土地登记即具有法律效力,直接关系着国家与私人土地产权的归属问题,因此,只有采取先进、精确的测量仪器与方法,才可以保证地籍测量最终成果的合理、准确、适时。本文认为,地籍测量实践教学可以通过转变实习指导思想,合理安排实习内容,创造必要的软、硬件条件,从而有效的引入GPS、RS、GIS等新技术,使学生了解并认识新技术,更重要的是学会如何运用新技术解决地籍测量中的实际问题。     

基于网络的教学模式改革四议

网络教育在我国取得了重要的成果,极大地推动了我国高等教育的改革与发展。但在进一步深化和推动网络教育的过程中也出现了一些新的问题,诸如教学模式改革中的课程改革与师生关系、教学设计与时空协调、课程改革与信息技术整和等。如果这些问题得不到妥善解决,将严重制约现代运程开放教育事业的发展。     

Reliability and validity of the Myotest® for measuring running stride kinematics

Accelerometer-based systems are often used to quantify human movement. This study’s aim was to assess the reliability and validity of the Myotest® accelerometer-based system for measuring running stride kinematics. Twenty habitual runners ran two 60 m trials at 12, 15, 18 and 21 km·h^?1. Contact time, aerial time and step frequency parameters from six consecutive running steps of each trial were extracted using Myotest® data. Between-trial reproducibility of measures was determined by comparing kinematic parameters from the two runs performed at the same speed. Myotest® measures were compared against photocell-based (Optojump Next®) and high-frequency video data to establish concurrent validity. The Myotest®-derived parameters were highly reproducible between trials at all running speeds (intra-class correlation coefficient (ICC): 0.886 to 0.974). Compared to the photo-cell and high-speed video-based measures, the mean contact times from the Myotest® were 34% shorter and aerial times were 64% longer. Only step frequency was comparable between systems and demonstrated high between-system correlation (ICC ≥ 0.857). The Myotest® is a practical portable device that is reliable for measuring contact time, aerial time and step frequency during running. In terms of validity, it provides accurate step frequency measures but underestimates contact time and overestimates aerial time compared to photocell- and optical-based systems.
