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

International 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 ...

Structural lobbying power? An exploration of patterns in preference attainment at varying levels of lobbying activity

Policy Studies Journal, EarlyView.
Abstract Studies of lobbying typically look at the extent to which interest groups realize political goals on issues they actively lobby for. Little is known, however, about the extent to which interest groups attain their political goals without making an active lobbying effort.

Research on Owner-Occupied Housing and CPI in China [PDF]

, 2016
消费者价格指数（CPI）在国民经济中具有重要的地位，是国家宏观调控参考的核心指数之一，因此编制准确的CPI具有重要的现实意义。但随着科技的进步和社会的发展，各种类型的新商品不断涌现，CPI的编制工作日趋复杂，如何编制准确的CPI面临日益严峻的挑战。目前，住房消费已经成为居民消费支出的重要组成部分，如何测度自有住房服务费，把其纳入CPI中，已经成为一个无法回避的棘手问题。现阶段，中国在该方面的研究相对不足，不利于编制准确的CPI。 基于以上分析可知，研究如何测度自有住房服务费 ...

Powerful representation of the poor? German welfare associations' narrative advocacy during COVID‐19

Policy Studies Journal, EarlyView.
Abstract The COVID‐19 pandemic sparked unprecedented experimentation in the German social assistance system, leading to changes previously considered impracticable by policymakers. This included a sanctions moratorium, easier access to benefits, and temporary cash transfers, all of which were advocated by welfare associations—key organized interests ...

基于变权重的变压器状态模糊综合评价方法

Gaoya dianqi, 2014
在传统的变压器状态评价方法中,常权无法客观反映变压器部分参数偏离正常值时对整体评价影响。基于此,笔者提出了基于变权重的变压器模糊综合状态评价方法。首先采用层次分析法确定变压器各影响因素指标的权重,然后考虑实际情况对各影响因素权重进行变权处理,减少评价的主观性,使变压器的状态评价结果更为合理。应用文中方法对实际变压器进行状态评价,验证了该方法的合理性和可行性。

抽水蓄能GIS电站VFTO幅值影响因素与权重分析

Gaoya dianqi, 2023
抽水蓄能电站与传统GIS电站相比，因开关操作更为频繁，产生VFTO概率更大，同时抽水蓄能电站由于地理环境限制需通过高压长电缆连接地上与地下两部分，接线形式的不同也会使产生的VFTO具有不同的特性。由于VFTO会严重威胁GIS设备、变压器和二次设备的运行安全，尤其是VFTO的幅值是导致设备绝缘损坏的重要因素，因此有必要对抽水蓄能GIS电站的VFTO幅值影响因素与权重进行深入研究。文中以某500 kV抽水蓄能GIS电站为例，采用仿真的方法计算分析了电站中VFTO幅值的影响因素和影响权重 ...

Marketization in Public Purchasing as a Route to Business Corporations' Institutional Power: The Case of Outsourcing Social Services in Israel

Policy Studies Journal, EarlyView.
ABSTRACT What are the conditions under which business corporations expand their institutional power? This paper argues that institutional power is affected by the architecture of the “acquisition regime”—the set of formal (and informal) rules that govern how states purchase public services.

高压断路器运行状态的变权模糊综合评判方法

Gaoya dianqi, 2009
根据高压断路器状态信息的多层次性和多因素性,建立高压断路器状态评估的层次型指标体系。利用模糊综合评判法,建立高压断路器运行状态评估模型,通过对各层评判因素的评估,综合得出断路器的具体运行状态。指标的权重先由层次分析法确定常权权重,然后引入基于均衡函数的变权模式,对常权进行修正得到变权,以提高状态评估的准确性,为高压断路器状态评估提供了一种新的思路。

建立坡面植被恢复群落质量评价体系的探讨

Shuitu Baochi Xuebao, 2004
利用构建AHP评判矩阵计算各评价指标的权重,根据对专家建议值的统计,确定4个分时期对整个坡面植被恢复群落质量的影响权重,并计算出坡面植被质量的最终值,然后根据给出的值域进行植被恢复群落质量等级划分。

Using Genetic Algorithms to Pick Stocks and Manage Portfolio in Technical Analysis System [PDF]

, 2016
在投资领域，如何高效地进行资产配置、获得高收益并控制风险是每个投资者进行投资决策时最为关注的问题，如何有效地选股和进行投资组合管理是一个广泛存在的难题。技术分析是主流的选股方法之一，是通过分析历史的市场数据如股价、成交量等，来预测股票未来的趋势的一种投资分析方法；遗传算法是模拟自然界物种进化的随机全局搜索最优解的算法，目前广泛应用于组合优化、机器学习、自适应控制、信号处理等领域；证券投资组合优化问题的实质就是有限的资产在具有不同风险收益特性的证券之间的优化配置问题 ...
