民族传统体育,作为一种文化的载体,与空间的关系尤为密切,与物质空间、符号空间和观念空间紧密相连,构成了一个文化—空间的动态系统。政府在此系统中具有导向性,能够直接影响到这些活动在实际空间中的展现,造成其空间的断裂或边缘化,在物质性空间实践方面,政府集中资源建设特定的体育场馆和活动场所,导致资源不均衡分配,地域失衡等问题;在精神性空间表征方面,政府过度干预导致符号化失真、文化削弱和商业化倾向;在生活性表征空间方面,政府主导的象征性认知限制了个人情感的真实表达。因此,政府需要重构民族传统体育空间,鼓励多元主体参与空间实践,深化意义价值建构和回归本体生活,以实现民族传统体育文化的持续传承和多维发展。通过重新平衡资源分配、强调文化深度、鼓励创新和个体情感表达,可以创造更丰富、真实和多样化的民族传统体育文化空间,促进文化传承和社会共融。

文章主要研究了“壮族三月三·民族体育炫”文化传承场域存在的问题及其实践路径。其文化传承场域存在新旧场域的冲突、文化资本的失衡和场域惯习的滞后等问题。新旧场域的冲突主要表现在传统性与现代性、商业化场域与传承场域之间的冲突。文化资本的失衡体现在技能的失传、传统知识的减少和现代化对传统体育项目的冲击等方面。场域惯习的滞后则主要体现在教育场域的教育方式、教材体系和传承力量滞后于传统体育文化的需求和挑战。在此基础上,文章提出了实践路径,包括塑造传统和现代融合场域、构建文化资本的共享平台和促进教育场域的现代转型等。通过以上研究,为保护和传承壮族传统体育文化提供了理论依据和实践指导。

为了促进电力资源在省间的余缺互济和在全国范围内的优化配置,我国正有序推进电力市场改革,逐步实现省间-省内市场的耦合和全国统一市场的演进。根据省间-省内市场耦合程度的不同,该文将演进过程划分为三个阶段:分层阶段、松耦合阶段和紧耦合阶段。进一步考虑跨区、跨省以及省内输电的输电费回收问题,跨区直流输电线路与区域内交流输电线路按照传输电量收费,省内线路按照用户负荷用电量收费。构建了面向不同输电费收取方式的出清模型与定价机制,分层阶段采用顺序出清,松耦合阶段采用双层迭代出清,紧耦合阶段采用统一出清,定价机制均采用节点电价定价机制。最后,利用IEEE 39节点和118节点系统进行仿真计算,验证了出清模型和定价机制的有效性,并分析了输电费对出清和定价结果的影响。

Kidney transplantation is the gold standard for the treatment of end-stage renal diseases(ESRDs). However,the scarcity of donor kidneys has caused more and more ESRD patients to be stuck on the waiting list for transplant surgery. Improving the survival rate for renal grafts is an alternative solution to the shortage of donor kidneys. Therefore, real-time monitoring of the surgical process is crucial to the success of kidney transplantation, but efficient methods and techniques are lacking. Herein, a fluorescence technology based on bright, photostable and long-circulating aggregation-induced emission(AIE) active NIR-II nano-contrast agent DIPT-ICF nanoparticles for the whole-process monitoring and evaluation of renal transplantation has been reported. In the aggregated state, DIPT-ICF exhibits superior photophysical properties compared with the commercial dyes IR-26 and IR-1061. Besides, the long-circulating characteristic of the AIE nano-contrast agent helps to achieve renal angiography in kidney retrieval surgery,donor kidney quality evaluation, diagnosing vascular and ureteral complications, and assessment of renal graft reperfusion beyond renovascular reconstruction, which considerably outperforms the clinically approved indocyanine green(ICG).
