Synthesizing Empirical Research on Learner Metacognition in Second Language Writing
International Journal of Applied Linguistics, EarlyView.ABSTRACT Despite considerable research interest in learner metacognition in second language (L2) writing, there is not yet a review that synthesizes the existing empirical findings and discusses their implications. To fill the void, this systematic review synthesized 39 empirical studies on learner metacognition in L2 writing and examined their salient

International Journal of Applied Linguistics, EarlyView.ABSTRACT Many existing rubrics for L2 argumentative writing prioritize form‐based linguistic accuracy and complexity while insufficiently addressing substantive argumentative rigor and effectiveness. This limitation is further complicated by cross‐cultural variation in rhetorical conventions and educational practices, which challenge the direct ...

Partisanship, Deservingness, and the Attitudinal Policy Feedback Process for Social Policy
Policy Studies Journal, EarlyView.ABSTRACT In an era of identity‐based partisan polarization, we examine whether social policies can still generate positive attitudinal feedback among beneficiaries. Drawing on nationally representative survey data, we demonstrate that partisanship conditions the policy feedback process through divergent perceptions of group deservingness.

Zhongguo shiyan zhenduanxue, 2007 目的分析我国吉林省地区朝鲜族和汉族人群血管紧张素转换酶（angiotensin converting enzyme,ACE）基因多态性的分布。方法应用聚合酶链反应（polymerase chain reaction,PCR）等技术检测81名健康汉族和96名朝鲜族ACE基因插入/缺失（I/D）多态性及其分布。结果汉族人群II型I、D型和DD型频率分别为34.38%,28.12%和37.50%;朝鲜族人群分别为38.27%,19.75%和41.98%,两组ACE基因基因型的分布差异无显著性（P=0.433）;

Regional News, Regional Bias? Evidence From Media Discourses and Welfare Decisions in Germany
Policy Studies Journal, EarlyView.ABSTRACT How do media representations of immigrants shape their treatment by street‐level bureaucrats? Despite a uniform federal legal framework, decision‐making varies substantially across local welfare offices. Though prior research links national news reporting and policy implementation, little is known about how regional variation in news reporting

, 2008 利用基因表达谱数据进行肿瘤亚型分类,对于癌症研究有着非常重要的意义。由于基因表达数据的维数很高,必须从大量基因中选取一些特征基因用于分类,才能取得好的效果。但以往方法所提取的特征基因,彼此之间存在较高的相关性。本文提出了一种基于高维向量分析的特征基因提取方法:首先利用基因与理想基因间相似度作为评价准则得到候选集,然后去除候选集中相关性强的冗余基因。用此方法选出的特征基因是与分类相关但彼此无关的 ...

Policy Studies Journal, EarlyView.ABSTRACT The examination of policy evolution has important practical implications, but current literature often only evaluates changing policy goals and instruments at the macro‐level, overlooking changes that occur at the more granular, micro‐level of policy text.
