Influences on cannabis policy design and adaptation in the American states
Policy Studies Journal, EarlyView.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

建筑热缓冲空间的设计理念和类型研究——以国际太阳能十项全能竞赛作品为例 [PDF]
, 2018 对建筑热缓冲空间的设计理念和策略进行分析,将其功能归结为热缓冲空间的蓄热能力和对换热速率的调节两个因素;以历届太阳能十项全能竞赛的参赛作品为例,依据热缓冲空间的形式和在建筑中的位置,将其分为中庭式、包围式、外廊式和辅助空间式四个类型,并分别举例阐述其特点。分析结果表明,热缓冲空间是一种综合性的节能设计策略,它通过被动式节能措施的合理整合,建筑主次空间的合理组织,能有效的改善建筑的内部环境,其设计理念为绿色建筑设计提供了新思路。国家自然科学基金资助项目:基于储能与热调节的生态建筑热缓冲空间设计研究 ...

Powerful representation of the poor? German welfare associations' narrative advocacy during COVID‐19
Policy Studies Journal, EarlyView.Abstract The COVID‐19 pandemic sparked unprecedented experimentation in the German social assistance system, leading to changes previously considered impracticable by policymakers. This included a sanctions moratorium, easier access to benefits, and temporary cash transfers, all of which were advocated by welfare associations—key organized interests ...

Modifying the Rotation of Molecular Motor Using Hydrogen-Bonding System
, 2014 “分子机器”这一概念起步较早，但是因为研究难度较大，发展较晚。近年来得益于合成技术、组装技术以及仪器检测手段的进步，分子机器的研究呈现一派蓬勃向上的势头。在大量获得了适合的分子机器结构的基础上，分子机器又因其在生物、光学、电学以及手性催化等方面表现出的特殊性质而倍受青睐。但是，促成这些性质产生的分子机器的内部运动却仍然处于难于驾驭的状态。尽管近年来有科学家致力于研究如何排除分子机器的转动部分在转动过程中的阻力，从而获得转速更高的分子机器，但仍然没有提出一个能够从慢到快，任意调节转动能力的方案 ...

Investigations on the microstructures and properties of Cu–Al–Mn–(Cr, V, Ti)shape memory alloys [PDF]
, 2017 摘要 Cu–Al–Mn基形状记忆合金具有良好的塑性和形状记忆性能，且成本低并易于切削加工，因此具有极其广阔的应用前景。然而，Cu–Al–Mn基形状记忆合金的临界应力以及疲劳强度都比较低，阻碍了其更多的发展应用。本论文采用合金化方法以Cu–Al–Mn合金为基体，分别添加了Cr、V和Ti元素，制备了Cu–Al–Mn–Cr、Cu–Al–Mn–V和Cu–Al–Mn–Ti三个体系的合金，并逐步采用金相、EPMA、XRD、DSC、压缩、TMA等测试方法，对各合金体系的微观组织结构、相变特性 ...

Policy Studies Journal, EarlyView.Abstract We examine whether and how public participation in policymaking contributes towards fostering stakeholder support for policy proposals formulated in the bureaucratic arena. We explain how key markers of procedural fairness describing both the participation process and policymakers' presentations of it during the decision justification stage co‐
