英国高校科研经费“双重资助体系”研究及思考

英国政府对高校的科研资助在长期实践中形成了以"高等教育拨款委员会拨款"及"研究委员会拨款"为主体的双重资助体系,形成了以决策分权化、完全经济成本补偿、创新科研评估制度为特征的政府资助高校科研管理体制。论文从比较研究的视角,对我国高校科研经费管理的实践进行相应的反思。

中国大陆地区2014年高校慕课课程建设情况调查

为了了解中国大陆地区高校对于慕课建设和利用的态度,特别是已经行动的高校的计划和定位,作者对中国大陆地区32所已经建设慕课且已经开展慕课教学的高校相关校级领导和项目主管人员进行了网络问卷调查,对调查结果进行了描述性统计分析,且与美国相关报告进行了同类数据对比。研究发现,大陆地区高校在慕课建设策略上有许多类似的地方,在慕课建设动机与定位方面与美国高校存在较大差异。最后,我们对部分高校的做法进行了点评,就高校建设慕课过程中可能出现的问题如何通过政策防范,做出了提醒。     

A Classroom Exercise to Examine the Trade‐off between Mission Capacity and Life Cycle Cost

This article presents a classroom exercise, centered on a simulation that has been used for 4 years in an MBA program to help students develop an understanding of the trade‐offs involved in managing capital assets in the public sector. Though often ignored in business schools, mission is a key criterion that must be considered when managing such assets, and acts as a surrogate for profit. The case presents a rich environment in which the impact of cost reductions (or additional investments) on mission can be quantified, and trade‐offs can be assessed and discussed. It gives students a chance to develop creative ideas for process improvement, and provides sufficient data for them to analyze the impact of their suggestions in a rigorous way.

The roots of reading for pleasure: Recollections of reading and current habits

Children's early literacy experiences are critical, yet it remains unclear whether memories of early reading instruction continue to be associated with reading habits into adulthood. We examined the association between recollections of reading experiences and present-day reading habits in an adult population. University students responded in writing to three open-ended prompts asking about their memories of reading during early childhood, elementary school and high school. They also completed two questionnaires inquiring about reading enjoyment and frequency in elementary school and high school. For the concurrent measures of reading, participants described their current reading habits in an open-ended prompt and completed an author recognition test. Results showed positive links between favourable memories of reading during elementary and high school years and present-day reading habits. Conversely, unfavourable memories during high school were associated with unenthusiastic present-day reading habits. We found that reading instruction in school forms long-lasting memories, and these memories are linked in meaningful ways with print exposure during adulthood.

Real time exploration and management of large medical volumetric datasets on small mobile devices—Evaluation of remote volume rendering approach

In this paper I present the architecture of system that can be used for real time exploration and management of large medical volumetric datasets. The new state of the art solution presented in this paper is an example of visual data management system. System prototype evaluation proved that it is possible to use low-powered (and cheap) up-to-date mobile devices with programmable GPUs as the remote interfaces for exploration of large volumetric medical data. The implementation was done with high-level programming language that enables portability between different hardware models. The lack of lossy compression enables to display high quality medical images visualizations without any simplifications and noises in frequency domain. The prototype of system is capable to remotely render and send to a client (for example cell phone or tablet) rendered data with frequency 30 fps with limited resolution during interaction. One second after the interaction is finished client machine receives full resolution image. The evaluation of the system was performed on volumetric computed tomography angiography image with approximate size 512³ voxels.     

基于最优权值探测的图像可逆信息隐藏研究

提出一种基于最优权值探测的图像可逆信息隐藏算法。该算法改进了现有的预测方法,利用最优权值探测原理提高预测像素值的精确受,使预测误差差值直方图更加紧凑、峰值更高。实验结果表明,相比其它可逆嵌入算法．该算法在保证图像质量的同时,提高了嵌入容量。算法整体性能高。     

基于自由分布式FDR阈值的NSCT遥感图像去噪

提出一种新的自由分布式(FDR)假设检验阈值和非下采样Contourlet变换(NSCT)相结合的图像去噪方法。该方法首先在NSCT域利用统计学中的自由分布式错误发现率(FDR)假设检验方法来设定阈值,再通过软阈值函数进行去噪,且不依赖信号的长度。实验结果表明：该方法能够更有效地去除。感图像的高斯噪声,提高图像的峰值信噪比;同时利用NSCT变换的平移不变性抑制了去噪中的伪Gibbs失真效应,较完整地保持了图像的纹理和边缘等细节信息,从而明显改善了图像的视觉效果。
