Changes in the transformative potential of action proposals in Finnish Red Lists from 1986 to 2019
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Red lists provide critical knowledge regarding biodiversity decline, especially in Finland, where broad assessments have been made regularly since the 1980s. They deliver information on the threat status of species and ecosystems, propose actions to guide conservation policy, and have the potential to spur transformative change.

基于MEEMD和SVM的贯通式同相牵引直接供电系统牵引网故障识别
Dianci bileiqi, 2021 针对贯通式同向牵引直接供电系统牵引网故障识别,提出了一种基于改进总体平均经验模态分解和支持向量机的故障识别方法。利用PSCAD仿真平台搭建3种不同类型(雷击故障,雷击干扰,接地故障)的故障模型,通过模拟仿真得到故障暂态电流,并对其解耦得到故障电流相模分量。采用MEEMD算法对故障电流相模分量进行分解,提取特征向量,通过SVM工具箱进行故障识别。为了验证SVM在故障识别中的优越性,通过对比概率神经网络故障识别,结果表明SVM在故障识别中具有更高的正确率。

How identity bias affects perceptions of conservation messages on social media
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Public support is essential for conservation, as public opinion can influence decision‐making and policy. Therefore, understanding whether bias toward conservationists due to their identity (identity bias) affects their perceived credibility and support for their recommendations is important.

Learner‐Focused Strategy Instruction From the Teachers’ and the Learners’ Perspective
International Journal of Applied Linguistics, Volume 36, Issue 3, Page 2358-2375, August 2026.ABSTRACT Numerous large‐scale quantitative studies have been conducted to yield a macro‐level picture of the effectiveness of strategy instruction. However, little is understood about learners' actual processing of strategy instruction and interaction with the teachers delivering it.

Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT This study introduces a dual‐layer protocol for diagnosing how formal institutional designs are implemented in practice in complex governance systems. The protocol builds two linked process maps; one for the formal rules and procedures (rules‐in‐form) and one for the routines actors actually follow in practice (rules‐in‐use).

Power Through Visibility: How Policy Narratives Matter in Climate Change Debate on X
Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT Research on policy narratives has shown that political actors employ certain narrative strategies in their competition for attention. Although we know that actors' narrative strategies coincide with existing power constellations (e.g., government vs. opposition), the ways in which they influence public attention remain largely unknown. In this

Gaoya dianqi, 2011 针对传统神经网络模式识别中存在网络结构难于确定、过学习、收敛速度慢、易陷入局部极小值等不足及标准支持向量回归机中未考虑各样本重要性的差异问题,结合变压器油中多组分气体监测传感器阵列,将改进型支持向量回归机应用于气体传感器阵列信号模式识别中。实验结果表明,改进后的模式识别方法在预测精度和泛化能力上都较传统神经网络和标准支持向量回归模式识别方法有明显提高,有效地解决了多组分气体监测传感器的交叉敏感问题。
