The press and political continuity in China: The case of the World Economic Herald

This paper, utilizing the method of case study, investigates the role of the Shanghai‐based World Economic Herald in China's political democratization in the 1980s, and analyses its relationship with the social changes of that period.

A prominent theme running through this study is that political democratization must be coupled with economic growth in order for the role of the press to change in China.

Results of the study suggest that the World Economic Herald, throughout its ten‐year existence, became more and more politically oriented and outspoken in its coverage of key political issues. The findings also reveal that in early 1989, the Herald waged an unprecedented struggle against the Party's tight control of the news media and for political democratization including press freedom. However, its role in promoting political change was restricted by the nature of China's reform movement, which was characterized by a separation of political reform from economic reform. The development and demise of the Herald provided a window through which it could be clearly seen how the press affected and was affected by the social changes in China in the historical period of the 1980s.

短距离助跑跳远的生物力学分析

为了探讨短距离助跑跳远这一练习方法的运动生物力学意义，本文对跳远运动员的短距离助跑和全程助跑跳远进行高速摄影和三维测力的同步测试．并通过对其分析和研究，结果表明：１）短距离助跑与全程助跑的水平速度、跳跃距离之差约为１０％；２）起跳时间和力作用于垂直方向的时间比全程助跑长；３）腾起角度大于全程助跑；４）身体重心腾起高度和滞空时间与全程助跑相同。

印度季风与西风相互作用在现代青藏高原产生连锁式环境效应

西风与印度季风两大环流是控制青藏高原气候与环境变化的决定性因素。研究显示两大环流的影响范围和程度具有明显的空间分异:基于降水稳定同位素实测与模型模拟发现青藏高原现代西风与印度季风的相互作用特征表现为3种模态,即印度季风模态、西风模态和过渡模态。基于湖泊沉积记录的分析,发现3种模态主控范围在历史时期不断发生变化。3种模态对现代青藏高原环境产生连锁式环境效应,使得该区的冰川、湖泊、生态系统变化具有明显的区域特征,具体表现为印度季风模态的冰川强烈退缩,湖泊趋于萎缩;西风模态的冰川趋于稳定甚至部分出现前进,湖泊趋于扩张;过渡模态的冰川退缩程度减弱,湖泊变化不明显。西风模态的植被返青期提前,印度季风模态的植被返青期推后,而过渡模态的植被过程比较复杂。     

高校图书馆馆际互借与文献传递服务的调查与分析

通过对我国768所本科高校图书馆馆际互借与文献传递服务的网上调查,分析了高校图书馆馆际互借与文献传递的类型、服务内容、服务方式、服务对象、收费及补贴情况,指出我国高校图书馆馆际互借与文献传递存在区域发展不平衡、服务发展水平参差不齐、服务对象存在局限性、缺乏统一的收费标准、版权意识淡薄等问题,提出了建立专门的协作机构和指导中心、提高对馆际互借与文献传递服务的重视、建立馆际互借与文献传递服务联盟、改进服务方式等对策。

Metal-organic frameworks enable broad strategies for lithium-sulfur batteries

The lithium-sulfur (Li-S) battery is considered to be a potential next-generation power battery system, however, it is urgent that suitable materials are found in order to solve a series of challenges, such as the shuttle effect and lithium dendrite growth. As a multifunctional porous material, metal-organic frameworks (MOFs) can be used in different parts of Li-S batteries. In recent years, the application of MOFs in Li-S batteries has been developed rapidly. This review summarizes the milestone works and recent advances of MOFs in various aspects of Li-S batteries, including cathode, separator and electrolyte. The factors affecting the performance of MOFs and the working mechanisms of MOFs in these different parts are also discussed in detail. Finally, the opportunities and challenges for the application of MOFs in Li-S batteries are proposed. We also put forward feasible solutions to related problems. This review will provide better guidance for the rational design of novel MOF-based materials for Li-S batteries.
