技术和制度哪个更重要?--关于图书馆制度的思考

对图书馆发展来说,技术和制度两者都重要,但制度高于技术。图书馆制度包括宏观、中观和微观三个层面。当今中国图书馆建设水平的落后,其主要根源在于制度的落后。     

图绘新闻:信息可视化与编辑室内的理念冲突

文章通过对相关学术文献中关于可视化新闻生产的话语构成的检视,以及对瑞士五家新闻机构的可视化编辑的深度访谈,全面勾勒数字化新闻生产与传统新闻生产之间存在的理念冲突,以及这种冲突对于新闻业发展变迁路径的潜在影响.研究发现,可视化新闻生产逻辑将"真实"界定为再现层面上的操作性概念,主张将美学的维度纳入新闻专业主义体系,同时提出了重构新闻价值标准的要求,这对传统新闻理念的权威性构成了显而易见的挑战.文章进而提出可视化新闻生产所遵循的"科学-艺术"观念结构有可能导致整个社会公共空间和文化结构的变迁.     

The powerful image and the imagination of power: the ‘new visual turn’ of the CPC’s propaganda strategy since its 18th National Congress in 2012

This paper adopts the academic tool of discourse analysis to examine the ‘new visual turn’ of the Communist Party of China’s propaganda work since the 18th CPC National Congress when Xi Jinping was inaugurated as the leader of Chinese Communists. A thorough review of the new visual means the Party uses for photojournalism, TV news, animated cartoons and online promotional videos points to three developments markedly different from traditional discursive strategies: a full embrace of Confucian ethics, articulation of the Internet-based popular culture and subcultures, and an effort to fortify Xi’s personal authority as a political idol. The paper concludes that the ‘new visual turn’ of CPC propaganda after the 18th Party Congress suggests that the Communist discourse has evolved to a new stage where sophisticated manipulation of sleek technological tools substantiates a rigorous, dynamic CPC discursive system more at ease with itself and more powerful than ever in shaping the mainstream political culture in China.

教育评价改革如何应对AI快速发展的挑战？

继ChatGPT之后,文生视频Sora横空出世。为了应对人工智能快速发展带来的挑战,我国学校教育正在加快推进 AI+教育,但是 AI+教育受唯分数、唯升学、唯学历的教育评价体系的影响,存在知识化、应试化倾向,人工智能在教育领域的应用还主要服务于应试,这既不符合教育改革方向,也难以培养适应人工智能时代的创新人才。应对人工智能快速发展的挑战,关键在推进教育评价改革,要坚定破除唯分数、唯升学的教育评价顽瘴痼疾,要在推进教育评价改革过程中,利用人工智能技术提高评价的效率与公信力。     

Serrated lithium fluoride nanofibers-woven interlayer enables uniform lithium deposition for lithium-metal batteries

The uncontrollable formation of Li dendrites has become the biggest obstacle to the practical application of Li-metal anodes in high-energy rechargeable Li batteries. Herein, a unique LiF interlayer woven by millimeter-level, single-crystal and serrated LiF nanofibers (NFs) was designed to enable dendrite-free and highly efficient Li-metal deposition. This high-conductivity LiF interlayer can increase the Li⁺ transference number and induce the formation of ‘LiF–NFs-rich’ solid–electrolyte interface (SEI). In the ‘LiF–NFs-rich’ SEI, the ultra-long LiF nanofibers provide a continuously interfacial Li⁺ transport path. Moreover, the formed Li–LiF interface between Li-metal and SEI film renders low Li nucleation and high Li⁺ migration energy barriers, leading to uniform Li plating and stripping processes. As a result, steady charge–discharge in a Li//Li symmetrical cell for 1600 h under 4 mAh cm⁻² and 400 stable cycles under a high area capacity of 5.65 mAh cm⁻² in a high-loading Li//rGO–S cell at 17.9 mA cm⁻² could be achieved. The free-standing LiF–NFs interlayer exhibits superior advantages for commercial Li batteries and displays significant potential for expanding the applications in solid Li batteries.     

Magnetically encoded 3D mesostructure with high-order shape morphing and high-frequency actuation

Inspired by origami/kirigami, three-dimensional (3D) mesostructures assembled via a mechanics-guided approach, with reversible and maneuverable shape-morphing capabilities, have attracted great interest with regard to a broad range of applications. Despite intensive studies, the development of morphable 3D mesostructures with high-order (multi-degree-of-freedom) deformation and untethered high-frequency actuation remains challenging. This work introduces a scheme for a magnetically encoded transferable 3D mesostructure, with polyethylene terephthalate (PET) film as the skeleton and discrete magnetic domains as actuation units, to address this challenge. The high-order deformation, including hierarchical, multidirectional and blending shape morphing, is realized by encoding 3D discrete magnetization profiles on the architecture through ultraviolet curing. Reconfigurable 3D mesostructures with a modest structural modulus (∼3 GPa) enable both high-frequency (∼55 Hz) and large-deformation (∼66.8%) actuation under an alternating magnetic field. Additionally, combined with the shape-retention and adhesion property of PET, these 3D mesostructures can be readily transferred and attached to many solid substrates. On this basis, diverse functional devices, including a switchable colour letter display, liquid mixer, sequential flashlight and biomimetic sliding robot, are demonstrated to offer new perspectives for robotics and microelectronics.
