Twelve Years Revisited: Translanguaging as Relational Pedagogy for Sustaining Language Learning Motivation

open access: yesInternational 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 ...

用于智能GIS设备状态实时评估的状态量综合权重法

open access: yesGaoya dianqi, 2014
在高压设备状态评估中,采用状态量固定的权重进行评判并不能很好地实时反映设备的状态,需要一种既能反映专家意见又能反映设备状态量实时数据的权重的赋值方法。笔者在阐述电网现行GIS设备状态评价导则的原理基础上,分析现行评估方法中存在的不足,提出了基于熵权理论的对固定的主观权重进行修正的方法,得到用于GIS设备状态实时评估的状态量综合权重。通过选择经验因子得到的综合权重既能反映专家经验,又能实时反应设备状态量的实时监测值的变化,用于状态评估时能够更准确地反映高压设备的实时状态 ...

Enacting Everyday Linguistic Citizenship: Language Life and Multi‐Membership Among Young Malaysian Chinese Immigrants in Australia

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT This article examines the language life of young Malaysian Chinese immigrants in Australia and their construction of multi‐membership as reflected in their daily language behaviors. It develops the concept of everyday linguistic citizenship and uses this concept as a theoretical lens to understand how the young adults build, maintain, and ...

大气颗粒物源解析的BP网络权重分析模型

open access: yes四川大学学报. 自然科学版, 2004
应用BP网络进行大气颗粒物源解析,将大气采集样本中的元素含量及其污染源成分谱构成训练样本集,用BP网络进行训练.由训练好的网络的权值分布可以计算出网络各输入节点的权重贡献率.根据输入节点的权重贡献率可以确定与其相联系的污染排放源的重要性,从而实现大气颗粒物的源解析.将BP网络权重分析法与其它源解析法应用于实例进行分析比较,结果表明:BP网络权重分析用于大气颗粒物源解析意义明确,方法简便可行.

Assessing Digital Interactional Competence for Second‐Language and First‐Language Chinese Speakers: Effects of Proficiency, Mode, and Setting

open access: yesLanguage Learning, EarlyView.
Abstract Measurement of interactional competence (IC) has attracted increasing interest in language assessment research. One key question is whether proficiency sufficiently accounts for IC, making separate IC assessment unnecessary. This study examines the IC–proficiency relationship using a test that assesses Chinese speakers’ ability to manage ...

考虑价格因素的并行模糊多准则时变权重云服务决策

open access: yes四川大学学报. 自然科学版, 2015
网络中云服务存储量的几何式快速增长使得云服务决策越加困难,为满足用户特殊需要并提供充足的决策依据,提出并行TOPSIS时变权重模糊云服务多准则决策算法.在并行TOPSIS改进中采用熵权重赋值形式赋予云服务相应的准则权重,使得权重的选择变得简单易行,并由此发展出时变权重提出改进TOPSIS评估机制,使用时变权重能够更好的对不同时间段的云服务质量(QoS)信息进行重要性区分,使得决策机制更加合理可信.然后基于分时模糊TOPSIS多准则决策机制,设计云服务选择的并行化融合决策框架,使得算法更趋近于工程应用 ...

There Is Always a Bigger Fish. Determinants of Power Perceptions in Swiss Biodiversity Policy

open access: yesPolicy 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 ...

基于可拓云模型与综合赋权的油纸绝缘阀侧套管状态评估

open access: yesGaoya dianqi, 2023
作为换流变压器的关键部件之一,阀侧套管的可靠性事关重大,为精准预测其运行态势,本研究提出了一种综合赋权与可拓云模型相结合的油纸绝缘阀侧套管综合评估模型。首先,根据运行经验及技术导则确定阀侧套管典型故障,总结出有效反映其状态的评估指标集。然后,计及评估边界的模糊性与随机性,考虑采用可拓层次分析法构建判断矩阵,通过计算具有正分量的归一化特征向量确定主观常权。为规避对专家经验的过分依赖,通过改进熵权法获取客观常权,进而确定综合常权因子。同时,针对个别指标严重劣化而常权无法灵敏反映的情况 ...
