基于用户的高校科研管理信息系统的分析与设计

开发科研管理信息系统是实现科研管理自动化、信息化的必要手段,系统开发时首先要进行系统的分析与设计。本文根据华南师范大学科研管理信息系统的开发经验,在分析系统需求的基础上,介绍了一种“基于用户”的系统设计方法。

Expeditionary Learning in Information Systems: Definition,Implementation, and Assessment

In the natural sciences, collecting, cataloguing, and comparing living specimens have long been a popular, collaborative mode of discovery and learning. New species are discovered, and the relationships between species are theorized. From Aristotle's “History of Animals” to Darwin's “On the Origin of Species”, and beyond, this process of learning through expedition has yielded bountiful knowledge and insights to students of science. In this paper, we propose that expeditionary learning can be applied to a softer science: the field of information systems. In the field of information systems, specimens (information systems) are created by humans, evolving with great speed. Expeditionary learning—where students collaboratively discover, catalog, and compare rapidly evolving information system specimens—is an innovative approach for learners in the IS field, and is effective in increasing IS program visibility and delivering significant, measurable community impact. Our results indicate that learning by expedition has a strong, positive community impact through educating external learners (such as high school and community college students, and the general public), and compares favorably to conventional experiential and service learning styles. Though expeditionary learning does not yield improved course evaluations, we demonstrate that learners’ perceived self‐knowledge and intentions to pursue the subject area are improved.

[目的/意义]研究数字经济时代，知识作为关键战略资源和核心资产，对理论和实践提出的新挑战。[方法/过程]采用文献资料调研法和理论分析法，基于网络实体系统（CPS）对数字经济时代知识管理的挑战和趋势进行分析阐述。[结果/结论]数字经济时代，知识管理在对象上对数据的获取和整合要求更高，在增值体系上对数据到信息再到知识的精度、实时性和准确性要求更高，异构整合和数据挖掘成为知识管理的关键，人机交互和人工智作为关键技术将发挥关键作用，在知识管理的目标上，数据驱动的价值创造成为核心。未来知识管理的发展将在战略上向实时动态精准决策演化，在架构上转向全域知识管理，在组织上通过无障碍知识流打造高效创新型组织，在内容上系统整合碎片化知识，在方法上重视基于人机交互的隐性知识转化，在技术上打造基于平台的知识图谱。     

Classroom Questioning with Immediate Electronic Response: Do Clickers Improve Learning?

A number of studies have focused on how students and instructors feel about digital learning technologies. This research is focused on the substantive difference in learning outcomes between traditional classrooms and classrooms using clickers. A randomized block experimental design involving four sections of undergraduate Operations Management classes was used to determine if clicker systems increase student learning of both quantitative and conceptual material in Operations Management. Learning was measured using the difference between the scores on an entrance examination and the final examination. The findings of this research provide evidence that the use of immediate feedback using a technology like clickers can have a positive impact on student learning as measured by test scores.     

略论“两制”并存视野下中美对外政策的不同选择——《当代世界经济与政治》课程中美对外政策问题断想

面对二战后世界主题转换,世界格局变化,经济全球化发展不平衡不断加剧的形势,中国推进“两制”的关系的理论创新和发展,而美国从其国家利益和全球战略出发,在“两制”关系上,死抱冷战思维,并利用一切手段、一切可能钳制和牵制中国,无视多样性和差异性,继续以社会制度和意识形态划线,强制推行美国所谓的民主、价值观和实用标准。
