International Journal of Applied Linguistics, EarlyView.ABSTRACT This study examines how foreign language teachers’ beliefs about the medium of instruction and translanguaging evolve over time by revisiting three in‐service teachers twelve years after their initial interviews. Using a qualitative longitudinal design, the study traces how translanguaging was initially framed as pedagogically deficient but ...

The simulation of Madden-Julian Oscillation and the optimal forecast error analysis [PDF]
, 2016 热带季节内振荡（在大气中以Madden-JulianOscillation为主，以下简称MJO），是全球季节内尺度预报的最主要信号来源，在天气气候系统的预报中起着非常重要的作用。作为目前发现的全球最强的季节内准周期信号，国内外普遍认为MJO的预报是联系数值天气预报和季节预报的桥梁，能够填补中期预报与短期气候预测之间的延伸期预报时段的“缝隙”。自20世纪70年代Madden和Julian提出以来，MJO现已在国际上获得了广泛关注，其机理研究和预报开展已经成为了全球气候研究的热门方向之一 ...

Accountability in Government Use of AI: Citizen Concerns and Preferences
Public Administration, EarlyView.ABSTRACT Government adoption of AI opens the “pandora's box” of accountability, a core aspect of public value. Despite the centrality of governmental AI accountability, citizens' concerns and preferences in holding governments accountable for AI usage remain poorly understood.

The mechanism of BaP and DDT co-exposure induced DNA damage via MAPK signal pathway [PDF]
, 2016 【目的】 苯并(a)芘(benzo[a]pyrene，BaP)是多环芳烃类化合物的典型代表之一，于各种环境介质中广泛存在，具有很强的致癌性，被国际癌症研究机构列为1类致癌物。滴滴涕(2，2-bis(4-chlorophenyl)-1，1，1-trichloroethane，DDT)曾是生产及使用范围最广的一类有机氯农药，在环境中非常难于降解，具有高亲脂性，可以对哺乳动物的肝脏、肾脏、神经等系统造成损害。BaP和DDT常共存于环境并可通过食物链的生物放大作用富集于人体，危害人类健康。因此 ...

Scientists in power plays: How substantive were scientists' narratives during the COVID‐19 pandemic?
Policy Studies Journal, EarlyView.Abstract Scientists who provide expert advice must engage with policy processes. Little is known about whether and how scientists deal with the political dynamics of policy processes that are inherent to policymaking. We study this question by building on the policy dimension concept within the Narrative Policy Framework.

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 ...

Research on the Antidepressive Mechanism of Chaiyuwendan Decoction Based on the Endogenous Cannabinoids system [PDF]
, 2016 目的： 1.观察柴郁温胆汤抗抑郁大鼠模型的药理效应； 2.从内源性大麻素系统探讨柴郁温胆汤抗抑郁的作用机制。 方法： 实验分两部分进行。 1.柴郁温胆汤抗抑郁大鼠模型的药效学实验：实验采用慢性轻度不可预见性应激21天复制大鼠抑郁模型。实验动物分为正常组、模型组、柴郁温胆汤组及氟西汀组，给药21天。观察大鼠体重变化，根据旷场实验和糖水消耗实验观察抑郁模型大鼠的行为学变化；采用Elisa法检测大鼠血清中5-HT、DA、ACTH、CORT的含量；采用酶法检测血清中TG、T-CHO、HDL-C、LDL ...

Narrative power in the narrative policy framework
Policy Studies Journal, EarlyView.Abstract The Narrative Policy Framework lacks clear and empirical explanations of power. Yet, the study of narratives is inherently the study of power in shaping policy outputs and decisions. We develop a conceptual model positing that expressions of power (power to, with, and over) may be discovered in narrative constructs (e.g., narrative structure ...

Malignancy-associated metabolic profiling of human glioma cell lines using 1H NMR spectroscopy [PDF]
, 2015 胶质瘤恶性转化的原因和机制不明，给临床诊疗带来极大困难。越来越多的研究表明肿瘤恶性转化与细胞代谢紊乱密切相关，但胶质瘤恶性转化相关的细胞代谢特点目前尚不清楚。因此，探寻不同恶性程度胶质瘤细胞的代谢轮廓，将有助于开发监测胶质瘤恶性进展的非入侵式生物标志物和靶向代谢通路的治疗策略。本研究收集5种不同病理级别瘤组织来源的人脑胶质瘤细胞系（CHG5／SHG44／U118／U87／U251），其中CHG5和SHG44为WHOII级来源；U118,U87和U251为WHOIV级来源。体外培养后，首先通过侵袭能力 ...

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 ...
