Digital Rights Activism in Multilevel Governance
European Policy Analysis, EarlyView.ABSTRACT Multilevel governance (MLG) without a clear hierarchical structure can create power imbalances among various actors, particularly in settings with overlapping jurisdictions and policy areas. This dynamic is especially pronounced in Internet governance, which faces a complex interplay of domestic laws, state interdependence, and heightened ...

Research on method of model selection in basement of high-rise building structure design [PDF]
, 2016 随着建设规模的不断扩大和土建技术的进步，现代高层建筑地下室的形式越来越多样化，工程环境条件更加的复杂，地下室结构设计时所需考虑的因素更多、所需处理的问题更复杂。地下室结构在整体结构中所占的比重越来越大，所需工期越来越长，使得地下室结构方案的选择对整体结构的影响也越来越重。地下室结构选型是地下室结构设计中的一个重要环节，具有涉及因素多，不确定性大，各因素间相互关联性大等特点。随着建筑工程信息化的发展，迫切需要一个准确性高、覆盖面广、操作便捷的地下室结构方案选型决策辅助工具，帮助结构设计师全面 ...

Rare Metals, EarlyView.ABSTRACT Harnessing solar energy for self‐heating presents an effective strategy to suppress surface ice formation. In this paper, we fabricated nano‐silver‐modified multilayer graphene sheets (Ag@MGs) that integrate photothermal and superhydrophobic properties for anti‐icing applications.

Research on the Improvement of the Internal Control System of GM Company —Based on Analysis of Internal Control Efficiency Evaluation System [PDF]
, 2015 企业内部控制的内容随着时代的变迁及经济的发展不断地丰富着。从上个世纪初以来，国内外的企业因为忽视内部控制的重要性，导致企业内部控制出现重大缺陷，从而产生严重经济后果的事件屡见不鲜，比如著名的安然、世通的会计造假事件等一系列的财务丑闻。因此推动了02年萨班斯法案的出台，还有04年概念全新的COSO报告的颁布：即《企业风险管理—总体框架》，内部控制理论发展到风险管理整合框架被公认为是内部控制理论研究的最高成就，然后美国的雷曼 ...

Policy Studies Journal, EarlyView.ABSTRACT We use grid‐group cultural theory (CT) to specify underspecified aspects of the Advocacy Coalition Framework (ACF). Our theoretical synthesis of CT and the ACF provides, first, an exhaustive typology of policy actors and their cultural cognitive biases that entail, guide, and constrain policy core beliefs about problem definitions and ...

A Research on C Container Line Company’s Grade Pricing Strategy [PDF]
, 2016 自2008年世界金融危机爆发后，全球经济增长减缓，集装箱运输市场货物运输需求大幅萎缩，而集装箱运力一直保持快速的增长，导致供过于求的现象日益严重。市场竞争的加剧使得市场的价格敏感度提高、运价波动更加频繁。而C集装箱运输公司经过四十几年的集装箱运营发展，在全球市场已跻身前十强，服务产品和服务模式越来越与市场其他公司趋同化，但经营业绩却与同业前三有相当的差距。在市场不景气、供大于求、竞争极其激烈的现状下，要想实现公司减亏直至盈利，必须找到业务关键环节即定价及运价管理进行改革 ...

Policy Studies Journal, EarlyView.ABSTRACT Despite extensive research on policy diffusion, the ways in which policy attention influences this process remain underexplored. This study addressed this gap by distinguishing between three types of policy attention—political speeches, policy issuance and field visits—and investigating their differential impacts when delivered by central and ...

Gaoya dianqi, 2019 层次分析法是一种进行定量和定性分析相结合的多目标决策分析方法,广泛应用于多特征量权重计算。文中对层次分析法进行改进,利用统计学的相关理论,把系统聚类分析方法和众数理论应用于层次分析法,结合专家所构造判断矩阵的一致性程度,通过加权平均算法得到指标的综合权重排序。改进的层次分析法不仅充分保留了原有判断矩阵的信息,同时全面考虑了专家个体判断结果的准确性和专家组综合意见。将改进的层次分析法应用于2个变压器油纸绝缘状态评估实例,算例结果表明:改进的层次分析法所得权重与传统层次分析法相比 ...

Gaoya dianqi, 2022 近年来，国内频繁出现高压输电电缆缓冲层烧蚀缺陷或故障，缓冲层烧蚀缺陷已成为影响输电电缆本体安全运行的重大问题，但目前电力部门对此类缺陷尚无较好的检测方法。文中在分析输电电缆缓冲层作用、类型及参数要求的基础上，对半导电阻水缓冲带和铜丝纤维编织布两种缓冲层结构进行了烧蚀缺陷的特征分析，并以两条故障电缆线路为研究对象，采用高次谐波法、宽频阻抗法、X射线检测法进行了检测方法的探索性试验研究。经研究分析，发现半导电阻水缓冲带和铜丝纤维编织布缓冲层结构的烧蚀缺陷虽表征现象相似，但引起烧蚀的原因不同 ...
