Fear in Public Policy Compliance: Citizens' Response to Crisis‐Induced Policies
European Policy Analysis, Volume 12, Issue 2, Spring 2026.ABSTRACT This article brings together social psychology and public policy literature in a mixed‐methods research design to explore how fear influences non‐compliance with challenging policies during crises. Building on Terror Management Theory, we argue that fear affects individual citizens' compliance tendencies.

People and Nature, Volume 8, Issue 3, Page 741-753, March 2026.Abstract Currently, scholarship on education to foster connectedness with nature primarily focuses on children. As adults likewise face the disconnection from nature and play a key role in influencing children, it is important to understand how they perceive, engage in, and benefit from relevant programmes.

基于多色探针熔解曲线分析技术的华法林个体化用药相关基因多态性快速检测方法 [PDF]
, 2019 华法林是一种广泛使用的抗凝剂，其治疗窗口较窄，患者间达到抗凝所需剂量的变异性大。已有研究表明CYP2C9*3 (rs1057910)、CYP2C9 IVS3-65G>C (rs9332127)、VKORC1 c.-1639G>A (rs9923231)和CYP4F2*3 (rs2108622)的单核苷酸多态性（SNP）是影响中国人群华法林敏感性的主要遗传因素。该研究利用多色探针熔解曲线（MMCA）技术，建立可同时检测4个华法林敏感性基因多态性的单管PCR反应体系，可在2.5 h内完成检测，能检测低至50
