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.

Gaoya dianqi, 2010 用梯度烧结法连接钨铜合金与纯铜或铜合金,并与传统的整体烧结、焊接、机械螺纹连接进行了对比分析,观察了结合界面和拉伸断口。结果表明,梯度烧结试样可以显著提高结合界面的抗拉强度（15%～30%）、降低电阻率（25%）。而且梯度烧结试样的界面表现为"犬牙交错"状,断裂方式为准解理,优于界面较为平整,断口呈解理断裂的其他几种连接方式。

Imagined Integration: The Logics of Japanese Immigrant Integration Policy
Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT As governments develop immigrant integration policies, they draw on and express conceptions about what successful integration looks like—what we call “imagined integration.” Yet this imagination likely displays variation that matters for implementation: integration policymaking is increasingly multilevel as it involves subnational layers of ...

Corporate Quasi‐Sovereignty: Big Tech and the Politics of Sovereign Authority in the Digital Age
Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT As private technology firms expand their control over critical infrastructures, questions of sovereignty and governance are increasingly displaced from states to corporate actors. Existing scholarship on sovereignty assumes that authority is either monopolized by states or shared through institutionalized public–private arrangements.

Zhendong Ceshi yu Zhenduan针对传统的线性超声理论在钢‑混凝土界面损伤检测中存在准确性低的问题，提出一种基于非线性超声调制理论的钢‑混凝土界面损伤识别方法。首先，在钢管混凝土内部嵌入智能骨料以激发高频超声信号，同时利用外部电磁激振器施加低频振动，从而调制出在频域上具有非线性特征的超声信号；其次，在钢管外壁的3个不同位置粘贴传感器，用于接收并记录经过界面调制的响应信号；然后，利用万能试验机开展加载试验，诱导钢‑混凝土界面产生不同程度的黏结失效，并定量分析界面裂缝扩展与损伤指标之间的变化规律；最后，通过对比分析验证该方法的有效性 ...

It Does Matter. A New Framework on the Influence of Policy Evaluation
Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT Governments worldwide have invested heavily in policy evaluation, providing many policymakers with a steady stream of evidence into the effectiveness, efficiency, or relevance of policies. Yet, despite these investments, systematic knowledge about the actual influence of policy evaluations remains surprisingly limited.

Shuitu Baochi Xuebao, 2023 以明确自然界中广泛存在的层状结构土壤孔隙分布特征为目的。选黄土高原典型坝地土壤剖面为研究对象,利用CT扫描技术分析耕作层、犁底层、心土层土壤三维结构,探讨层状土孔隙参数随土层结构变化及界面层孔隙特征。结果表明:(1)瘦长型孔隙(孔隙形状系数≤0.2)是各土层土壤孔隙的主要形态。各土层的孔隙参数具有明显差异。耕作层的总孔隙度最高,大孔隙(≥1 mm)分布较多;犁底层孔隙总数量最高,含有较多孤立的小孔隙(≥0.1~0.5 mm)和微小孔隙(≥0.06~0.1 mm),但连通性最差 ...
