生产·生活·生态:我国冰雪体育产业融合发展的三维结构解析

冰雪体育产业的融合发展对于促进冰雪体育产业的高质量可持续发展具有重要的现实价值和决策意义,而融合发展能否实现,还依赖于冰雪产业系统科学的系统结构来有效引导和推动。在明确冰雪体育产业融合发展的形成逻辑和本质特征的基础上,立足于生产、生活、生态,构建冰雪体育产业融合发展的三维结构,对其要素构成、功能作用、性能表现进行解析,并提出相应的建议。研究认为：在要素构成上,三维结构包含了相互支撑、相互配合、有机衔接的生产维、生活维、生态维等3大核心要素及其 15个基本要素。在功能作用上,生产维为生活维提供消费资料,影响生态维的空间格局;生活维为生产维提供劳动力、资本、技术、信息等资源,对生态维进行保护、修复、治理、丰富;生态维为生活维提供生态产品,为生产维提供生产资料。在性能表现上,三维结构具备高效度、协调度、持续度、融合发展度。在此基础上,从利用市场机制、优化供给侧、统筹消费需求、保护和开发生态资源等4个方面提出了助推冰雪体育产业融合发展三维结构健康运行的相关建议。     

洛克的自然法理论

洛克是西方法律思想史上第一位系统而完整的提出古典自然法的法律思想家,其自然法思想独到之处在于:以财产权为核心的自然权利学说,以人民权力为核心的社会契约论,法治与分权理论以及法律与自由的辩证关系理论;这些思想为近、现代民主法治建设提供了有益的启示。     

化合物4CdCl2·CeCl3·12H2O的相化学合成和荧光性

利用相平衡的方法合成了化合物4CdCl2.CeCl3.12H2O,对该化合物通过荧光分光光度计进行表征。结果表明该化合物以260nm波长光进行激发时,在波长340 nm和655 nm处具有荧光光谱;以860 nm和570 nm波长光激发时,在波长335nm处具有上转换发光光谱。     

强权与和平的冲突:9·11 事件后的另类解读

强权与和平一直是国际政治理论的基本概念.现实主义认为,强权即和平,或者说强权是和平的必要保障.9·11事件以其突然性和毁灭性给全世界以巨大的震撼,反恐成为世界各国的主导意识.此时强权即和平或者美国治下的和平还具有现实意义吗?该文将通过对现实主义的这个观点进行理论分析和实证分析,以寻求答案.     

Chemically processed Nb-doped SrTiO3 films and properties

Homogeneous, crack-free SrNb_xTi_1−x O₃ thin films on (110) silicon substrates were successfully fabricated by sol-gel processing. The optimum route and conditions were systematically investigated. Sr(OAc)₂ glacial acctic acid solution, after being refluxed and reacted with tartrate, formed Sr(OAc)₂(C₄H₆O₆)₂; Ti(OBu)₄ formed Ti(OAc)_4−x (AcAc)_x after having the ligand partially exchanged with AcAc, while Nb(OC₂H₅)₅ formed (OAc)₂Nb(AcAc) (C₄H₆O₆) by exchanging of ligand in glacial acetic acid with (CH₃CO)₂O. All the metal species after undergoing partial hydrolysis and polymerization with hydroxyl or oxygen, formed SrNb_xTi_1−x O₁₃ cluster sol. Methyl cellulose (MCL) caused SrNb_xTi_1−x O₃ sol to have polymeric structure and easily form films. SrNb_xTi_1−x O₃ films with perovskite were subsequently formed after being annealed at 650∼750 °C for 60 min in 25% N₂+75% H₂ (volume ratio) atmosphere. Resistivity of the SrNb_0.1Ti_0.9O₃ films at room temperature was 64 μω·cm, a particular T ² temperature dependence of the resistivity, from 25 K up to room temperature, was observed.

How academic librarians involve and contribute in research activities of universities? A systematic demonstration in practice through comparative studies of research productivities and research impacts

Participating in research and teaching activities of universities, and then providing valuable information and policy suggestions are an important task of academic librarians. This paper demonstrates systematically in practice that how academic librarians can involve and contribute in the research activities of universities. Our demonstration is launched through comparative studies of research productivities and research impacts among universities. These universities are divided into two counterparts. One is the Chinese universities which aim to construct the world-class mathematics discipline, and the other is the university which already owns the world-class mathematics discipline. During these comparative studies, we demonstrate in practice that how to seek the research question, how to collect and process the data, how to design the research methods, how to analyze the data, and how to propose policy suggestions. Contributions of this paper are twofold. The first aspect is a systematic demonstration in practice. This demonstration shows to academic librarians that how to involve and contribute in the research activities of universities. The academic librarianship thus can be strengthened, as it provides a way for us academic librarians to promote our roles in teaching and research activities of universities. The second aspect is to gain insights in the research productivities and research impacts of Chinese universities which aim to construct the world-class mathematics discipline. During this process, we design a bibliometric indicator for evaluating the research impacts of universities based on academic papers, launch comparative studies with the university that already owns the world-class mathematics discipline, and propose policy suggestions for China to scientifically achieve its goal. This also provides references for other countries to launch similar studies.     

将拓展训练引入高校体育教学的可行性研究

拓展训练和体育教学的目的、教学方法手段等都是相同的,简化和改良的拓展训练项目也比较易于融合到体育教学中,在高校开展拓展训练是可行的;拓展训练引入高校体育教学应加强安全管理,定期对体育教师进行培训,加强拓展训练与其它体育项目的融合,建设联合的拓展训练基地。     

《诗经·载驰》诗意考辨

《诗经·载驰》中对许穆夫人是否归国的理解历来分歧较大。这种分歧不仅影响对诗作思想的领会,也影响了对字词的理解。本文试提出自己的看法,来论证《载驰》的诗作本身反映了许穆夫人回宗国吊唁是事实,而非设想。     

论卡西尔的艺术本质观——艺术是人类感性符号形式的创造

德国哲学家恩斯特·卡西尔深刻地分析和批判了西方历史上流行的两种艺术本质观:模仿说和表现论,沿着康德艺术自律论的方向,提出艺术是"人类感性符号形式的创造",从一个全新的视角进一步推进了人类对艺术本质的认识。
