严寒地区高速铁路混凝土基床聚氨酯保温特性试验研究

基于严寒区京沈客专朝阳试验段路基基床的温度监测资料分析,研究不同厚度聚氨酯保温板对高速铁路路基混凝土基床温度变化特性影响.测试结果表明:①铺设聚氨酯保温板能够有效阻断严寒区环境与路基基床间的热量传递,保温效果与板厚相关;②地温大多数时间呈阳高阴低现象,同时阴、阳坡路基温差波动幅度随埋深逐渐减小;③基床表层阴、阳面各测点的温度变化起始时间一致,而阴面的冻结时间比阳面晚一个月.由此表明,保温板能够有效降低环境与混凝土道床之间的热交换,但是对路基阴、阳坡的影响存在差异.建议在严寒地区高速铁路路基阳、阴坡可以采取不同厚度的聚氨酯保温板,减小阴阳坡地温差异,保持季冻土路基温度变化稳定.     

How novel actors achieve a positive reputation: A case of prep schools with elite‐level hockey programs

How are novel organizations able to build a positive reputation while attempting to enter into a system with established organizations? To address this, we examined the field of elite‐level amateur hockey. Private Secondary Schools (PSS) are novel in that they offer a nontraditional pathway for players with respect to fielding elite‐level hockey teams. Findings from interviews with PSS with elite‐level hockey programs revealed that PSS highlight their Selection Processes, Player Development Practices, and the enhanced Player Experience in an effort to build a positive reputation. This study contributes to the literature on reputation by showing that novel organizations can build a reputation through highlighting the unique value they add. Copyright © 2016 ASAC.

Coping with coopetition—Facing dilemmas in cooperation for sustainable development: The case of the Dutch smart grid industry

This paper is amongst the first to examine coopetition strategy for sustainable development at the network level. Companies who want to successfully implement complex innovative technologies that support sustainable development need to collaborate with other actors of the innovation ecosystem, including their competitors, so that they can develop standards, interoperable products, pool knowledge, and resources and bundle forces to compete against other technologies. Collaboration with competitors brings benefits, but also many risks. We investigated how firms cope with these risks when establishing an innovation ecosystem to implement a new technology in society. We conducted research in the Dutch smart grids sector and explored how these firms minimize inherent risks of coopetition. We found that system‐building actors in the Dutch smart grid field not only minimize inherent risks, but from the start of their collaboration they implement so‐called enablers to prevent these risks upfront.     

新时代背景下创建党建引领基层社会治理新模式的探索——以兰州市城关区为例

随着我国社会发展的不断推进与创新,对于执政基础的巩固、在最大限度内保证党的执政能力等均成为使基层党建可以获得良好效果的主要手段,并且使工作在不断的实践探索中获得更好的成效。但是,以党建引领基层社会治理的过程仍然存在众多问题,其中包括形式化严重以及做表面功夫等。因此,如何在新时代的背景下,通过党的全面领导将党与群众紧密地联系在一起,从而确保党建工作可以在基层发挥更强的社会治理职能,已成为基层社会治理模式探索并创新的主要内容。

当代艺术审美理想的迷失与重建

中国当代艺术审美理想的迷失从根子上说是有些中国作家和艺术家社会背叛的结果,从美学上说,不但是席勒当年所批判的恶劣倾向的沉渣泛起,而且消解了人对自己的尊严的捍卫和对自由的追求。中国当代艺术审美理想的重建就是要求中国作家和艺术家精神寻根,按照美的规律创造。
