International Journal of Applied Linguistics, EarlyView.ABSTRACT This study examines multilingual practices in research interviews, focusing on English lexical insertions in Chinese‐language research interviews with teachers of Chinese in Australian secondary schools, and treating these code‐switches as analytically meaningful rather than incidental.

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 ...

The Effects of Gen‐AI on Situated and Future‐Driven Academic Writing Motivation
International Journal of Applied Linguistics, EarlyView.ABSTRACT Despite the increasing use of Generative Artificial Intelligence (Gen‐AI) in education, there is still a significant gap in understanding its effects on the situated‐ and future‐driven motivation in academic writing. This longitudinal design‐based research sought to explore variations in academic writing motivation of 110 Chinese university ...

四川大学学报. 自然科学版, 2012 扩散结构的好坏直接影响了分组密码的扩散速度和安全强度,以分支数尽可能大的线性变换为分组密码算法的扩散结构是设计分组密码的一种重要方法,线性变换的构造可通过可逆矩阵的构造完成.利用高效的算法搜索出几类可逆广义字变换,在此基础上提出一类计算上可行的基于GF(232)上移位和比特异或的最佳扩散变换构造的算法.该变换特别适合硬件实现,广泛用于分组、序列以及HASH等密码算法的设计中.

Predictive evolutionary genomics: principles, validation, and practice
New Phytologist, EarlyView.Summary Climate change and habitat loss are driving rapid evolutionary responses in populations world‐wide, which creates an urgent need for evolutionary forecasting in conservation and agriculture. Such forecasting can be categorized into three time scales: trait‐based models that use multivariate quantitative genetic equations to project correlated ...

Gaoya dianqi, 2020 精确的变压器深度饱和模型是分析电网过电压暂态过程的基础。而目前端口试验的方法只能得到额定运行时等效电路模型的参数,却无法得到过电压下深度饱和区的参数。该文提出利用数值仿真的方法确定三相变压器深度饱和等效电路模型参数,数值仿真的方法分为两种,包括基于端口数值试验的方法和基于电磁场分布计算磁阻方法。前者通过磁场和电路耦合的方法在变压器的端口设置开路或短路状态以确定等效电路参数,后者利用变压器各部分的磁通和能量的积分结果计算磁阻,再转换得到等效电路参数。计算磁阻的方法更适用于分析拓扑复杂 ...

There Is Always a Bigger Fish. Determinants of Power Perceptions in Swiss Biodiversity Policy
Policy Studies Journal, EarlyView.ABSTRACT The Advocacy Coalition Framework (ACF) views power as crucial in policy processes, but the nature of coalition power, its determinants, and how to empirically measure it remain understudied. In this article, we use a mixed method approach and social network analysis to explore power relationships in the biodiversity policy subsystem in ...

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.
