Policy Studies Journal, EarlyView.ABSTRACT Why did Australia go from the White Australia Policy, which excluded non‐whites, to institutionalizing multiculturalism policy in the 1970s? This question defies traditional political ideologies of the major political parties, which had long supported the White Australia Policy. This article is a rare empirical demonstration of the Five‐Thread

Simulation Analysis and Optimization of Coach Seat and Passenger Coupling Impact System [PDF]
, 2015 据相关资料表明，在客车碰撞所造成的人员伤亡中，因乘员与座椅之间的二次碰撞或座椅与车体相连部位的失效占了相当大的比例。为了提高我国客车在碰撞事故中对乘员的保护能力，客车座椅及其固定点强度的国家标准GB13057-2014目前已从推荐性标准升级为强制性实施标准。为了保证所设计的座椅能满足新法规要求，必须深入研究客车座椅及其固定支架的结构变形及乘员在碰撞过程中的伤害情况。 汽车碰撞过程是一个瞬间的复杂的物理变形过程，它包含了几何非线性，材料弹塑性变形非线性和零部件间复杂的接触非线性等特征 ...

Policy Studies Journal, EarlyView.ABSTRACT As the Narrative Policy Framework (NPF) begins to unpack issues of power and narratives, the main focus has been on power‐over and domination rather than more transformative notions of power‐to and empowerment. This article draws on insights from gender and policy studies and suggests that the NPF benefits from adopting a multifaceted notion ...

The Role of Public Finance to Address the Global Finance Gap for Drinking Water Services
World Water Policy, Volume 12, Issue 1, February 2026.ABSTRACT Meeting SDG target 6.1 for drinking water requires addressing the finance gap between the funds available from tariffs, taxes and transfers, and the life‐cycle costs of sustaining these services. While there are li‐mitations to applying repayable finance to address this gap, governments can be well suited to support both drinking water ...

Development of Warm White LED on Near UV LED Excitation Phosphor [PDF]
, 2016 由于白光LED具有节能、减排等诸多优点，白光LED固态照明是目前各个国家和地区都在积极推动的技术和产业。但常规的白光LED光谱偏离太阳光谱，损伤人眼，不适合于室内照明。采用近紫外光激发三基色荧光粉制备暖白光LED是解决本难题的最佳方案。与蓝光LED激发荧光粉制作白光LED技术方案相比，采用紫外或近紫外LED激发三基色荧光粉制作的暖白光LED，其发光光谱的质量只与荧光粉配比相关，紫外LED本身不参与可见光光谱的发光，因此白光光谱的均匀性和一致性可以得到保证 ...

Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Urgency to save species from extinction has prompted increased investment in law enforcement in protected areas. To date, such law enforcement has largely focused on increasing costs and reducing opportunities for offending. However, these resource‐intensive approaches are not always effective and can contribute to conflict between people and ...
