教育传播学视角下对教育技术学科定位的再思考

本文尝试基于教育传播学的视角重新审视技术的内涵,明确提出对技术的界定和分类———显性技术和隐性技术,深入阐述技术与教育技术的存在关系,并在此基础上提出只有正确看待技术,合理协调技术和客观评价技术才能有效引领人们对技术的理解以及对教育技术学专业定位的认识,进而提出对教育技术学科定位的再思考和再探讨,旨在促进这一学科的持续健康发展。     

基于ARCS动机模型的现代教育技术公共课教学策略初探

教育技术公共课是高校在校生提升信息意识和信息素养的一门必修课,但其教学效果一直不尽如人意。本文从分析当前教育技术公共课的现状入手,结合ARCS动机模型理论,提出了教育技术公共课改进的若干对策,以期提高这门课程的教学质量。     

一种机群相对定位方法

针对机群协同编队导航定位问题,通过分析机群协同编队的特点,建立了编队成员的相对运动模型并引入视觉观测信息,提出了一种基于相对导航的机群联合组网定位方法,理论分析及仿真结果均表明了联合定位结果能达到机群中各成员惯导位置输出的平均水平,有效地减缓了编队系统的定位误差发散速度。     

基于重力加速度的自对准算法在摇摆台上的验证

摇摆基座条件下陀螺和加速度计测量的地球自转角速度和重力加速度受到了摇摆运动的干扰,无法根据陀螺和加速度计的输出直接获得初始姿态矩阵。针对这一问题,通过验证实验证明了基于重力加速度的对准算法的有效性,并依据实验结果从理论上对该方法的对准误差进行了分析,提出了进一步提高对准精度的措施。

On the production of victory: Empirical determinants of battlefield success in modern war

Using a data set of historical battles from 1600 to 1973, this paper analyzes the empirical determinants of tactical success in modern war. Based on a reduced form approach we consider key elements of military theory as production factors for combat success as an output of a military production function. The paper focuses on the relationship of material and non-material factors to battlefield success, and especially on the role of superior force strengths. Contrary to the emphasis on technology which can be found in the recent literature, our estimation results indicate that numerical superiority has retained its crucial role for battlefield performance throughout history. In general, human elements of warfare, like leadership, morale and surprise, have continued to be important determinants of battle outcome despite technological progress in weapons.     

The German arms industry in a European context: A study in successful downsizing

Defence offsets rank as one of the most important and controversial topics within the broad field of defence economics. Arms vendors are likely to view offsetting investment as a distraction, fearful of its potential to hurt the bottom line. By contrast, policymakers in the arms purchasing countries see offsets as an opportunity to extract technology transfer, as well as employment, investment and export sales opportunities. Establishing the actual impact of offsets, however, is not easy. The subject is shrouded in secrecy and myth, with anecdote and generalisation pervading even the intellectual press. This paper seeks to break the mould by offering an empirical case study of the role of offsets in Malaysian defence industrialisation.     

Iron Cannot Fight 1 – The Role of Technology in Current Russian Military Theory

Contemporary Russian military theory is dominated by three schools of thought: the ‘traditionalists’, the ‘modernists’ and the ‘revolutionaries’. On the role of technology in future warfare, the traditionalists argue for both high tech and massive forces at the same time. The modernists are ready to trade manpower for technology, whereas the revolutionaries give technology full priority. Both the traditionalists and the modernists believe Russia, because of the country's technological lag and limited resources, should respond asymmetrically to the Western technology challenge. The revolutionaries, on the other hand, maintain that Russia must respond in kind. If not, the country will no longer be able to defend its sovereignty. The currently ongoing radical reform of the Russian military is a partial victory for the modernists, but which model or mix of models that will dominate in the future is first of all dependent on the Russian military's purchasing power and the state of the domestic defence industry.
