International Journal of Applied Linguistics, EarlyView.ABSTRACT This paper examines the features of metadiscourse across different teacher moves in university linguistics classroom discourse and the teaching strategies reflected in its use. The results reveal that teachers employ diverse metadiscourse during classroom interactions to support student reasoning.

On the precursor of the flux and path variation of Kuroshio in the East China Sea [PDF]
, 2016 本文利用区域海洋模式系统（RegionalOceanModelingSystem，ROMS），针对东中国海海域（渤海、黄海和东海），建立了高分辨率三维斜压海洋模型，其长期模拟结果成功再现了东中国海和西太平洋暖池部分海域的主要海洋环境特征，及黑潮月、年际和年代际的变化。在此基础上，通过大量敏感性试验，研究了在7天尺度上可以导致PN断面处黑潮流量发生异常变化的前期征兆以及吐噶喇海峡处黑潮路径变异的前期征兆；另外，基于模式模拟结果、沿海验潮站水文数据等资料，本文也分析了东中国海海平面演变的空间差异 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Online tutoring platforms (OTPs) are an increasingly popular way for learners to study languages and for teachers to earn money. On many OTPs, individual teachers are responsible for attracting potential students via self‐branding. While scholarship has examined OTP teachers’ self‐branding practices and identified some of the most popular self‐

Gaoya dianqi, 2012 由于绝缘材料的电阻率具有非线性和各向异性,故在计算换流变压器阀侧绕组直流电场时需要考虑到绝缘材料的非线性和正交各向异性。笔者采用ANSYS二次开发技术,计算了在考虑绝缘材料电阻率随场强和温度变化情况下的非线性直流电场及非线性各向异性直流电场。计算结果表明,在考虑绝缘材料电阻率非线性和各向异性的情况下,电场分布与不考虑这些条件下的分布有很大的不同。因此,换流变压器阀侧绕组的直流电场应该按非线性各向异性场计算。

International Journal of Applied Linguistics, EarlyView.ABSTRACT With the internationalisation of higher education, English medium instruction (EMI) has become increasingly common in non‐English‐speaking contexts. However, research highlights a range of challenges in EMI implementation, including insufficient collaboration between content and language teachers, limited professional development opportunities

energy transport in low-dimensional disordered systems [PDF]
, 2016 本论文研究低维无序系统的热传导以及能量输运性质，重点探索局域化和非线性相互作用所起的作用和引起的效应，揭示非线性作用对局域化的影响，特别是其引起的解局域化的机制和过程。我们发现对称与非对称相互作用都会引起一维局域化系统解局域化，但是它们对于系统的热传导行为以及解局域化的过程的影响有着定性的不同。相较于对称的相互作用来说，不对称的相互作用表现出更强的解局域化能力，而且在解局域化区域，不对称的相互作用的系统表现出正常的热传导；而对称的相互作用的系统的热传导依然是反常的 ...

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

Tidal Asymmetry in the Xiamen Bay:Numerical Model Approach [PDF]
, 2015 本文基于ROMS（RegionalOceanModelingSystem）建立厦门湾的三维水动力变边界模型，模拟厦门湾的水动力情况，并首次对厦门湾的潮流不对称现象进行了研究。厦门湾潮流的实测数据表明，湾内存在潮流不对称现象，猴屿站和鼓浪屿站最大涨落潮流速不一致。将模型结果与实测数据进行验证，结果表明模型能够很好的反映厦门湾内潮位和潮流的变化情况，并再现了猴屿站和鼓浪屿站的潮流不对称现象。 厦门湾为正规半日潮海区，M2分潮为主要分潮，由模型结果得到了厦门湾内M2、S2、K1 ...
