Exploring Chinese International Students’ Intercultural Competence in Australian University Classrooms: Challenges and Opportunities

International Journal of Applied Linguistics, EarlyView.
ABSTRACT With the increasing number of Chinese international students in Australian universities, intercultural competence has become a critical factor influencing their interactions with Australian tutors in university classroom settings. Existing research often examines students’ intercultural competence from a single‐method or single‐perspective ...

Investigation of Improving Luminous Efficiency for GaN-Based Vertical-Structured Light Emitting Diodes [PDF]

, 2014
宽禁带III-V族氮化物半导体材料具有优异的物理和化学特性，其合金材料的禁带宽度在0.7~6.2eV范围内连续可调，对应的波长覆盖了红外到远紫外光的范围且任意组分的合金均为直接带隙。因此已被广泛应用于制作高亮度发光器件、光电探测器以及高温、高频和大功率电子器件等，是近年来光电子材料领域研究的热门课题。尤其是基于大功率蓝紫光波段的发光二极管（LEDs）在推动全球固态照明的应用进程中担当着重要角色。半导体照明能够广泛应用的关键是提高氮化物LED芯片的发光效率 ...

Assessing Argument Quality in L2 Argumentative Writing: Integrating Argument Elements and Intellectual Standards

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 ...

Volumetric properties of ions in DMF-water mixtures(离子在DMF-水混合溶剂中的体积性质)

Zhejiang Daxue xuebao. Lixue ban, 2003
利用精密数字密度计测定了298.15 K氯化钾及氯化铵在N,N-二甲基甲酰胺(DMF)-水混合溶剂中的密度,计算了氯化钾及氯化铵的表观摩尔体积和极限偏摩尔体积,得到了相关离子的极限偏摩尔体积和迁移偏摩尔体积.结果表明,当DMF浓度为15%~45%时,K+和的极限偏摩尔体积均表现增加趋势;而Cl的极限偏摩尔体积在同一DMF浓度范围内则表现为逐渐减小.利用溶质溶剂和溶剂-溶剂相互作用对结果进行了讨论.

A first-principles investigation of spin gapless Heusler compounds M2CoA (M = Mn, Ti; A = Al, Si) [PDF]

, 2015
M2CoA型Heusler化合物Mn2CoAl、Mn2CoSi、Ti2CoAl和Ti2CoSi具有独特的电子结构和磁学性质。Mn2CoAl是一种自旋无带隙半导体，其电子结构的一个自旋方向存在能带间隙，另一个相反自旋方向的导带和价带边缘在费米能级相接触，呈现无带隙半导体特性。Mn2CoSi、Ti2CoAl和Ti2CoSi被预测为自旋半金属，其电子结构的一个自旋方向存在能带间隙，另一方面，费米能级贯穿半金属相反自旋方向的能带，呈现金属特性。不管是自旋无带隙半导体还是自旋半金属，载流子都具有极高的自旋极化率 ...

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.

First-principles calculations of perpendicular magnetic anisotropy in Fe1-xCox/MgO(001) [PDF]

, 2015
近年来，垂直磁隧道结由于在磁记录、磁随机存储器、微波探测器以及磁敏传感器等方面的广阔应用前景引起人们广泛的关注。其中由单质Fe或者FeCo基合金与单晶MgO(001)结合形成的垂直磁隧道结具有高隧穿磁电阻、高热稳定性、低临界翻转电流的优点，是人们研究的重点。虽然大量的研究取得了丰硕的成果，但是横亘在FeCo/MgO隧道结应用之前的一个重要问题是铁磁层的垂直各向异性难以在较高厚度下保持，提高了材料制备工艺的难度。为此，本文拟研究Fe/MgO中垂直磁各向异性随Fe厚度变化的内在机制，通过优化Fe ...

Coalition Breakdown and Subsystem Exit

Policy Studies Journal, EarlyView.
ABSTRACT Why actors choose to work together (or not) to advance policy has been the central area of inquiry within the Advocacy Coalition Framework (ACF). Existing research has mainly emphasized the pathway towards coalition formation and evolution, underscoring the stable patterns of allies and opponents observable in policy processes over a decade or

Novel Manganese Dioxide Nanoparticles Enhance Chemotherapy Response by Priming Tumor-Associated Macrophages toward M1-like Phenotype and Attenuating Tumor Hypoxia [PDF]

, 2016
缺血乏氧是肿瘤微环境的重要特征之一，肿瘤的缺血乏氧不仅促进了肿瘤细胞的侵袭转移，同时还增强肿瘤对化疗药物的耐药性。肿瘤相关巨噬细胞（Tumor-associatedmacrophages，TAMs）浸润在肿瘤微环境之中，通常在肿瘤缺血乏氧区域富集。肿瘤相关巨噬细胞作为肿瘤微环境的重要功能细胞，其在肿瘤细胞的增殖、侵袭、转移、化疗耐药等肿瘤进展的各个阶段均发挥着重要作用。鉴于此，我们提出一种新型的肿瘤治疗策略，以期改变肿瘤微环境的同时，增强实体瘤对化学治疗的疗效 ...
