21世纪:新闻教育最需要什么 总被引:7,自引:0,他引:7
在研究当今中国新闻教育改革的问题时,首先必须思考“教育的目的是什么?,”“最好的教育是什么?”作者在考察美英较发达的新闻教育后,认为,教育的目的,是解决有限的人生精力与无限的知识之间的矛盾。最好的教育,是能用最小的教育成本最快培养人实现最大的人生价值。尤其需要研究:一是学制问题;二是如何认识、处理好通识教育与专业教育的关系。具体到新闻教育改革,应着重解决:重视对新闻专业职业精神的强调和培养,避免将新闻专业人才培养目标与传播专业人才培养目标简单地混同起来;因地制宜,创造条件,加强对新闻实际操作能力的培养。 相似文献

XrML是一种基于XML的权限描述语言,它描述了数字内容使用时相关的权限、条件等。作为MPEG-21的权限表达语言,XrML已经成为国际标准化组织的一种标准,得到大力的推广。本文设计并实现了一个XrML验证器,该验证器的特点是具有良好的扩展性和广泛的适应性,系统精简紧凑,可以用在嵌入式系统、手持设备等对资源占用有着较高要求的场合。目前该XrML验证器已经被应用到了中科院计算所的知识创新工程“基于IPv6的内容分发系统”。 相似文献

This article proposes the incorporation of learning science into the programming and operation of public libraries. Learning science, a multidisciplinary field spanning cognitive science, psychology, neuroscience, economics, anthropology, and linguistics, has identified proven methods for enhancing learning at any age. The article highlights some of the tools and insights that are most relevant to libraries in their role as centers for informal learning. 相似文献

Libraries have been the key to preserving culture and historic legacy for centuries. One such treasure cataloged in The Pennsylvania State University (Penn State) Libraries is a collection of over 33,000 Sanborn? Fire Insurance Maps. Originally kept safe in metal drawers, the library has embarked on a journey to digitize this abundance of information, combine it with other media such as photographs, and make it accessible through a web interface. Inspired by these efforts, we accessed this information and took it to the next level. Using state of the art 3D modeling and immersive technologies, we created a historic 3D model and immersive experiences of Penn State, exemplarily for the 1922 campus. The resulting experiences can be accessed through the web but also through head mounted displays (HMDs) and mobile phones in combination with VR viewers such as the Google Cardboard. Additionally, they can be used anywhere in the world or on the campus itself as a way to enable remote and in situ experiences and learning. Immersive experiences let us connect to the past, the present and the future, and as such offer value to digital cultural heritage efforts. 相似文献

The analysis of the joint kinematics during swimming plays a fundamental role both in sports conditioning and in clinical contexts. Contrary to the traditional video analysis, wearable inertial-magnetic measurements units (IMMUs) allow to analyse both the underwater and aerial phases of the swimming stroke over the whole length of the swimming pool. Furthermore, the rapid calibration and short data processing required by IMMUs provide coaches and athletes with an immediate feedback on swimming kinematics during training. This study aimed to develop a protocol to assess the three-dimensional kinematics of the upper limbs during swimming using IMMUs. Kinematics were evaluated during simulated dry-land swimming trials performed in the laboratory by eight swimmers. A stereo-photogrammetric system was used as the gold standard. The results showed high coefficient of multiple correlation (CMC) values, with median (first–third quartile) of 0.97 (0.93–0.95) and 0.99 (0.97–0.99) for simulated front-crawl and breaststroke, respectively. Furthermore, the joint angles were estimated with an accuracy increasing from distal to proximal joints, with wrist indices showing median CMC values always higher than 0.90. The present findings represent an important step towards the practical use of technology based on IMMUs for the kinematic analysis of swimming in applied contexts. 相似文献

INTRODUCTION Shield tunnel method has become the most pre- ferred method in city tunnel construction because of its excellent attributes: little effect on surrounding environment, fast and safe construction, outstanding performance in earthquake resistance, etc. (Zhang et al., 2004). In different shield tunnels, the arrangement and number of segments are different, but the whole assembling process is generally the same. The as- sembling process begins with A2P, then A1P, A3P, BP, CP, … 相似文献
