Non‐Members in a Tight Spot: How Norway Navigated Autonomy in EU Pandemic Management
Review of Policy Research, Volume 43, Issue 3, May 2026.ABSTRACT This study offers new insights into how closely integrated non‐member states navigate tensions between autonomy and dependence when urgent policy responses are required within complex supranational frameworks. It does so by exploring how these non‐members exercise their “wriggle room”—a tailored sub‐category of the broader concept of autonomy ...

A Study on the Active Life Expectancy and the Influencing Factors of the Elderly in China [PDF]
, 2016 随着人口老龄化社会的发展，老年人的生活质量备受关注。一些现象表明：健康一定可以长寿，但长寿不一定健康。在我国，老龄化进程不断加快，为使我们的老龄化社会更加和谐，我们有必要关心老年人的生活质量，关注老年人处于健康的寿命长度。 本文选用中国老年健康影响因素跟踪调查项目（CLHLS）的2008~2011年纵向数据，并运用多状态生命表法，分别从不同年龄、不同性别、不同城乡居住地、不同受教育程度、不同婚姻状况、不同烟酒状况、不同身体锻炼情况、不同患病状态等方面来计算健康预期寿命，并分析不同因素对健康预期寿命的影响。

Investigating the Origin of Topological‐Hall‐Like Resistivity in Zn‐Doped Mn2Sb Ferrimagnet
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Skyrmions and other chiral spin textures have been extensively studied as potential building blocks for novel spintronic devices. Hall‐resistivity anomalies that deviate from magnetization scaling, known as the topological Hall effect, have been widely employed as evidence for the presence of chiral spin textures in magnetic materials. However,

带并联电抗器的交流特高压输电线路单相自适应重合闸故障识别方法
Gaoya dianqi, 2013 为使单相自适应重合闸避免重合于永久性故障,需对线路故障类型进行准确的识别。笔者针对带并联电抗器的交流特高压输电线路,计算瞬时性故障与永久性故障时中性点小电抗电压与故障线路端电压幅值比,分析发现,两种故障情况下其比值明显不同,因此利用中性点小电抗与故障线路端电压幅值比为判据,可准确判别瞬时性与永久性故障。大量ATP/EMTP仿真结果表明,该方法可以有效识别不同故障类型,且判别方法简单可靠性高。

Does Board Heterogeneity Matter for Firm Financial Performance? A Case Study of the Commercial Banking Sector in Sub-Saharan Africa [PDF]
, 2016 政府政策、媒体和游说团体通常都鼓励董事会的多样化，因为他们都秉持这有助于提高公司绩效的理念。在本文中，我们探究是否存在证据表明追求董事会的多样化尤其关注董事的年龄、性别、种族、任期以及独立性对公司的财务业绩会有实际的好处。使用面板数据分析，我们检测了来自撒哈拉以南的非洲地区41个不同国家的202家银行2010—2014年的数据。我们发现没有经验证据表明在撒哈拉以南的非洲，董事会的年龄、经验和独立性的多样化会影响公司业绩。然而，我们发现存在有力的证据表明 ...

High‐Value Targeted Conversion of Copper Slag as LiFePO4 Material for Lithium‐Ion Batteries
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The massive stockpiling of copper slag (CS) presents severe environmental and resource‐waste challenges. Existing strategies for CS valorization typically yield low‐value‐added products. Herein, we propose an innovative hierarchical regulation approach to transform CS into high‐performance LiFePO4 (LFP) cathode materials.
