Maintaining Research Documents with Database Management Software

Summary

This article reviews the development and delivery of a Higher Education course module as part of a large European University's Integrated Masters Program operating through a regional network of Rural Area Training and Information Opportunities (RATIO) telematic centres. The aim of the project was to provide remote learners living in the southwest of England with computer-supported solutions to access higher education as part of a technology-assisted distance education program. The module represented a shift from traditional educational delivery systems by using instructional courseware via an Internet Web site. Personal communications with module participants were conducted with the use of e-mail and videoconferencing information technology (IT) resources. Out of the original sixteen participants who enrolled in this Masters course module, four actually completed the learning sessions and two submitted final assignments. This article considers the key lessons learned from this attrition rate and shares the mainly positive experiences of the remote tutor and the students engaged in this initiative. The implications regarding the use of the Internet for delivering higher education course modules through online distance learning are discussed in the light of cautions learned from this research project and important practical recommendations for future practice are made.

Differences in electronic exchanges in synchronous and asynchronous computer-mediated communication: the effect of culture as a mediating variable

Two hundred and eighty undergraduates from universities in two countries were asked to read didactic material, and then think and write about potential solutions to an ill-defined problem. The writing was conducted within a synchronous or asynchronous computer-mediated communication (CMC) environment. Asynchronous CMC took the form of email exchanges between American learners only, Southern European learners only, and American and Southern European learners together. Synchronous CMC was restricted to dyads consisting of American–American, Southern European–Southern European, and American–Southern European students dialoguing. Additionally, a number of Americans and Southern Europeans were each paired with a content-“mirroring” computer-generated partner to account of the effect of thinking with an unresponsive partner in synchronous CMC. Results revealed that dyadic learners in asynchronous CMC used significantly more reasoning skills to think about solutions to the problem, while dyadic learners in synchronous CMC exchanged significantly more personal knowledge and features of emotion. However, the tendency among dyadic learners to include emotional features in their dialogues was mediated by their cultural background.     

关于屈原诗歌艺术特色问题的论争

在中国的学术界,屈原的诗歌艺术特色问题历来就存在着诸多的争议,而争议的焦点又在于他的诗歌艺术特色的繁复性构成和形象指认。本文试图运用现代文艺学的理论和已有的研究成果对之进行新颖的探讨,并提出自己的见解,认为屈原在其诗歌艺术中所要塑造的是一个有似于“狂人”的形象。     

A group intelligence-based asynchronous argumentation learning-assistance platform

Structured argumentation support environments have been built and used in scientific discourse in the literature. However, to the best our knowledge, there is no research work in the literature examining whether student’s knowledge has grown during learning activities with asynchronous argumentation. In this work, an intelligent computer-supported collaborative argumentation-based learning platform that detects whether the learners address the expected discussion issues is proposed. After each learner presents an argument, a term weighting method is adopted to derive input parameters of a one-class support vector machines classifier which determines if the learners’ arguments are related to the discussion topics. Notably, a peer review mechanism is established to improve the quality of the classifier. Besides, a feedback module is used to issue feedback messages to the learners if the learners have gone off on a tangent. The experimental results revealed that the students were benefited by the proposed learning-assistance platform.     

大学足球课程异步教学模式研究

异步教学模式是在实施素质教育过程中探索出来的一种新的教学方法,是一种以学生的个体学习为基础。能将学生的学习与老师的异步指导统一在一个教学过程中进行的现代教学模式。大学足球课程异步教学模式是教师与学生的教学双边关系,包括学生的异步化学习模式和教师的异步化指导模式。学生的异步化学习模式是自学-启发-复习-作业-改错-小结六个步骤的有机结合;教师的异步化指导模式包含分类教学、个别教学、全体教学的内容,并有“四步指导法”和弹性教学法两种有代表性的教学方法。     

Straight Talking: The Nature of Effective Career Discussion at Work

Many employees need help from others in managing their careers, and it is likely that much of this help will be given in the context of a face-to-face discussion, either in a formal setting or more informally. Drawing on the accounts of 104 UK employees who had participated in helpful career discussions, this paper examines with whom and in what settings effective career discussions took place, and the skills and personal qualities displayed by givers and receivers of support. A wide range of individuals provided this form of support. The most important skills and qualities shown by givers of support were: the personal qualities of interest, commitment and trustworthiness; challenging and facilitative skills; giving honest feedback; and providing information.

二阶多智能体系统的领导—跟随异步脉冲一致性

针对具有时延的二阶多智能体系统领导—跟随异步脉冲一致性问题,假设每个多智能体采样邻接点信息的时刻互不相同,针对无向切换网络拓扑的多智能体系统,提出一种切换拓扑下有领导者的异步脉冲一致性控制协议。首先对该协议进行理论分析;然后构造 Lyapunov 函数,并利用 Lyapunov 稳定性理论与树形转换法给出多智能体系统在该控制协议下达到异步一致的充分条件;最后提出实例并进行 MATLAB 仿真。仿真结果表明,在脉冲控制下跟随者与领导者误差渐进趋于零,验证了该一致性协议有效性。
