Journal of Linguistic Anthropology, EarlyView.Abstract This article argues that social actors' media ideologies about digital interfaces are key to the enregisterment of online activities. Focusing on an online register emergent from user activities around Year, Hare, Affair (YHA)—a state‐aligned Chinese animation—I explore how different metadiscourses evaluate this register by entextualizing ...

Efficient Simulation Methods for Reinforced Concrete Columns with Encased Steel in High-rise Building Structures [PDF]
, 2016 型钢混凝土柱在建筑结构中往往是主要的承重构件之一，使用合适的数值模型分析其力学性能对高层结构抗震分析有重要的意义。本文综述了目前文献中已有的低含钢率恢复力模型相关研究，分析了其理论、计算流程和算法，并在通用有限元软件OpenSees中编程实现。本文详细推导了模型中基本参数的确定方法，并用于模拟实际高层建筑结构中的型钢混凝土柱。首先，本文用恢复力模型模拟了单根型钢混凝土柱的试验，通过对比验证了模型的精度，研究了其计算效率。其次，本文将恢复力模型用于理想32层高层结构中的单排型钢混凝土构件静、动力分析中 ...

New Phytologist, EarlyView.Summary The importance of marine angiosperms, or seagrasses, as foundation species for marine coastal ecosystems is in marked contrast to their low species number of only 70 described taxa. Seagrass species tend to have very similar overall morphologies dictated by hydrodynamic forces of the ocean environment.

Policy Studies Journal, EarlyView.Abstract Collaboration in governing complex environmental challenges is the norm. However, collaboration does not necessarily deliver desirable outcomes, and the importance of forming collaborative networks that effectively address the challenges at hand has been emphasized in theory and practice.

Latent target groups—A methodological contribution of social identities to policy design research
Policy Studies Journal, EarlyView.Abstract Research on policy design underscores the importance of accurately identifying target groups to effectively design policy measures that change individual behavior, address societal problems, and achieve policy objectives. However, empirical research on the composition and characteristics of target groups is rare and primarily draws on a ...

The Mechanism and Effect of Financial Channel of External Economic Imbalance——Based on the Empirical Study of China and the United States [PDF]
, 2017 外部经济失衡是许多国家和地区面临的一个宏观经济问题，也是国际经济和金融领域研究的热点。21世纪以来，随着全球金融一体化的迅速发展，国际资本流动规模增大，各国对外资产与对外负债规模快速增长，外部经济失衡的衡量与调整方式发生了新变化。传统的基于经常账户变动的贸易调整渠道已经无法有效解释外部经济失衡调整，而汇率和资产价格变动带来的估值效应这一金融调整渠道对外部经济失衡的调整作用在不断强化。因此，对金融调整渠道的机制及效应的研究具有理论和现实意义。 本文基于Gourinchas和Rey（2007 ...
