Influences on cannabis policy design and adaptation in the American states
Policy Studies Journal, Volume 53, Issue 3, Page 723-746, August 2025.Abstract Despite federal prohibitions, three‐quarters of states had implemented medical marijuana laws (MML) and one‐third had implemented recreational cannabis laws (RCL) by 2020. State policy designs varied considerably, and we focus on policy development and maturation in policy implementation, examining factors influencing design features of policy

The Palestinians in a Transforming Middle East: Adapting or Stagnating
World Affairs, Volume 188, Issue 3, Fall 2025.ABSTRACT This article examines the profound stagnation and decline confronting the Palestinian national movement in the aftermath of the October 2023 war in Gaza. It argues that Palestinian political fragmentation has coincided with an evolving regional landscape that increasingly sidelines Palestinians. On the international stage, waning US engagement,

检测GIS固体绝缘内部放电缺陷的特高频和X射线数字成像联合方法研究
Gaoya dianqi, 2018 相比超声波局部放电检测法,特高频局部放电检测法对GIS固体绝缘内部放电缺陷检测灵敏度和定位精度较高,但无法确证此类缺陷部位和类型,据此制定的设备检修策略难以保证完善、准确。因此,文中研究了特高频局部放电和X射线数字成像联合检测GIS固体绝缘内部放电缺陷的方法,使用特高频局部放电检测法对固体绝缘缺陷进行检测和定位后,在设备检修期间应用X射线数字成像技术对缺陷进行可视化确证。该方法在某110kV变电站110kV GIS的带电检测中成功发现隔离开关绝缘拉杆内部电树枝缺陷 ...

Effectiveness of protected areas in the Caucasus Mountains in preventing rangeland degradation
Conservation Biology, Volume 39, Issue 3, June 2025.Abstract As land use intensifies globally, it increasingly exerts pressure on protected areas. Despite open, nonforested landscapes comprising up to 40% of protected areas globally, assessments have predominately focused on forests, overlooking the major pressures on rangelands from livestock overgrazing and land conversion.
