International Journal of Applied Linguistics, EarlyView.ABSTRACT Multilingual students in Anglophone universities often operate in survival mode. While translanguaging supports learning, critical gaps remain in understanding how translanguaging pedagogies transform and sustain motivation in English‐dominant contexts.

Dynamic Raman imaging system of high spatio-temporal resolution and Its key technologies [PDF]
, 2016 拉曼光谱技术由于其无损、非接触、不受水分子干扰等特点而广泛应用于各个领域，其中显微拉曼光谱技术已发展成为微区检测、化学分析方面强有力的工具。然而目前大多数显微拉曼光谱仪的拉曼扫描成像速度仍无法满足电化学反应过程动态监测的要求。本文研究结合“适用于高时空分辨原位电化学显微拉曼光谱仪的研制及其应用研究”项目的目标和要求，通过集成拉曼扫描成像技术和宽场拉曼成像技术，构建具有高时空分辨特性的动态拉曼成像系统。在显微拉曼光谱仪具有的高空间分辨率的基础上，进一步提高成像系统的时间分辨，从而实现动态拉曼信号的检测 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT While English‐medium instruction (EMI) and English for Academic Purposes (EAP) courses are designed to promote language and content learning, their prevailing English‐only approaches often undermine students’ learning motivation. Against this backdrop, translanguaging has gained recognition as an effective pedagogical practice to support ...

Research of High-Dimensional Time-Varying Network Analysis Method [PDF]
, 2016 网络分析尤其是相关网络分析方法一直以来应用于多领域的研究当中，在大数据浪潮不断革新数据分析方法的背景下，网络分析也面临着高维数据的处理问题。基于网络结构稀疏性的假定，许多相关研究提出关于高维网络数据的网络结构估计方法，这类方法主要对固定时期内的静态网络结构进行估计。然而，由于大量个体以及不确定影响因素的参与，网络个体间的关联结构也充斥着复杂性，结点间的关联结构也有可能随着时间的推移而发生动态的变化，仅凭借传统的静态网络分析并不能较好地刻画出网络结构的演化特征。 在本文的研究中，在详细论述相关网络理论 ...

The underappreciated roles of fog and dew on vegetation and biocrusts
New Phytologist, EarlyView.Summary Fog and dew represent minor components of ecosystem water budgets in most ecosystems. However, fog and dew can play an essential role in ecosystem dynamics and are particularly important for water‐limited systems. In addition to serving as direct water inputs, fog and dew can influence microclimate and water redistribution, thereby promoting ...

Basic income trials and the politics of scale: A research agenda
Policy Studies Journal, EarlyView.Abstract The growing popularity of basic income has led to extensive trials of the policy in numerous settings across the world. However, analysis of the politics of basic income, and in particular the political dynamics preceding and resulting from trial programs, lags. In response, we propose a research agenda that uses political scale to investigate

Remote Sensing Retrieval Algorithms and Spatial-temporal Characteristics of POC in the South China Sea [PDF]
, 2015 颗粒有机碳(ParticulateOrganicCarbon,POC)是海洋生物地球化学过程的重要组成部分，随着光学技术和遥感手段的进步，在不同时空尺度下监测POC取得很大突破。本文以2011年国家自然科学基金委南海共享航次现场光学数据为基础，探索适用于南海POC反演的海色卫星遥感算法，将算法应用到卫SeaWifs遥感反射比Rrs(λ)数据，得到南海月平均POC，并分析其在季节和年际时间尺度上的时空变化特征。 首先，依据现场观测遥感反射比Rrs(λ)和POC，用多种方法来估算南海表层POC浓度 ...

Powerful representation of the poor? German welfare associations' narrative advocacy during COVID‐19
Policy Studies Journal, EarlyView.Abstract The COVID‐19 pandemic sparked unprecedented experimentation in the German social assistance system, leading to changes previously considered impracticable by policymakers. This included a sanctions moratorium, easier access to benefits, and temporary cash transfers, all of which were advocated by welfare associations—key organized interests ...

Phytoplankton cell death and programmed cell death in Xiamen Bay [PDF]
, 1900 浮游植物是海洋最重要的初级生产者，其生长和死亡显著影响海洋生态系统结构和生物地球化学作用。然而，目前对自然海区浮游植物死亡的调查研究还较少，对浮游植物死亡的机理和生理生态响应也并不清楚。本文主要利用现场调查研究和实验生态相结合的手段，研究亚热带海湾浮游植物死亡及其影响因子，利用分子生物学技术手段研究东海原甲藻(Prorocentrumdonghaiense)对营养盐限制条件下的死亡机理-细胞程序性死亡。取得的主要结果如下： 1.厦门湾浮游植物的死亡比率 ...

Policy Studies Journal, EarlyView.ABSTRACT Why did Australia go from the White Australia Policy, which excluded non‐whites, to institutionalizing multiculturalism policy in the 1970s? This question defies traditional political ideologies of the major political parties, which had long supported the White Australia Policy. This article is a rare empirical demonstration of the Five‐Thread
