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

Gaoya dianqi, 2019 油中溶解气体分析是监测电力变压器运行状态最常用的方法之一。针对现有标准对油中溶解气体体积分数预警阈值设定单一和裕度过大等不足,提出了一种基于数据统计和分布模型的220 kV变压器油中溶解气体体积分数动态预警方法。首先,对某电网近10万条220 kV变压器油中溶解气体体积分数数据进行统计与分类处理,并建立了油中溶解气体体积分数的分布模型;然后,根据油中溶解气体体积分数实际预警数据统计结果,通过分布模型的逆累积运算计算得到动态预警值,从而实现了一种油中溶解气体体积分数的动态预警方法;最后 ...

Automatic vibration fault detection of coal mine explosion-proof electrical equipment based on One-Class Support Vector Machine [PDF]
The vibration generated by explosion-proof electrical equipment in coal mines during operation can compromise its mechanical integrity, leading to fastener loosening, component wear, and changes in the structure and vibration modes of the equipment. This

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

Gaoya dianqi, 2023 电力变压器绝缘老化评估为电网的长期安全稳定运行提供了技术支持，在保证非破坏性试验的基础上，对绝缘状态进行诊断也是一直以来的研究热点。文中基于广义维纳过程对变压器建立老化模型，通过相关试验数据得到老化诊断指标，从而衡量变压器绝缘老化状态。对变压器健康状态进行分级，采用上述模型预测最短降级时间，相比于直接进行寿命预测，短期预测可以将未来人为操作信息纳入模型，最大化解决信息挖掘不充分的问题。最后对老化评估模型的相关分布参数进行优化求解，采用内蒙古电网设备真实历史数据迭代训练 ...

Governing by Ambiguity: Sociotechnical Imaginaries of Platforms in China
Policy &Internet, Volume 18, Issue 2, June 2026.ABSTRACT Besides clear policy directives, the unresolved and open‐ended elements in policy communication also create discursive politics. This article argues that ambiguity in policy communication reflects the state's exercise of power within a fractured sociocultural landscape.

Political Cycles, Electricity Policy, and Mexico's Economy
Latin American Policy, Volume 17, Issue 2, June 2026.ABSTRACT Electricity reform in Mexico should stimulate economic growth, improve energy efficiency, and reduce greenhouse gas emissions. This article evaluates the successes and failures of reform and draws lessons across political cycles by analyzing changes in political dynamics—often tied to policy reversals—and the legal framework during the pro ...
