Climate policy support in the UK: An interaction of worldviews and policy types
Policy Studies Journal, Volume 53, Issue 2, Page 388-413, May 2025.Abstract Understanding predictors of climate policy support is important for tackling climate change. Previous research demonstrated that policy support is partially driven by cultural worldviews. Yet, treating policies as a homogeneous concept, this literature neglected the existence of different policy types.

Gaoya dianqi, 2016 针对微网系统在离网模式下,给不平衡负荷供电之一问题,文中采用三相四桥臂作为双模式变流器拓扑,并设计了并网与离网双模式工作及并离网模式切换的控制策略,可解决离网模式下不平衡负载引起的电压不平衡问题。根据不同模式下三相四桥臂变流器的数学模型,采用电网电压定向的电感电流闭环控制策略实现并网模式运行,采用双同步旋转坐标系下的正负序电压控制以及零序电压的比例谐振控制策略实现离网模式运行。同时,采用一种控制模式的平滑切换方法来实现并网与离网两种模式的独立运行。最后,通过仿真对采用的双模式变流器控制策略进行了验证 ...

Combating infections under siege: Healthcare challenges amidst the military assault in Gaza
World Medical &Health Policy, Volume 17, Issue 1, Page 188-213, March 2025.Abstract The ongoing Israeli military assault on Gaza has caused a devastating collapse of healthcare infrastructure, resulting in an unprecedented surge in infectious diseases. The destruction of sanitation systems, restrictions on medical supplies, and displacement of civilians have created an environment conducive to the rapid spread of waterborne ...

World Medical &Health Policy, Volume 17, Issue 1, Page 129-148, March 2025.Abstract Patients with kidney failure need dialysis or a kidney transplant to survive. Living donor kidney transplantation (LDKT) is the best therapeutic option, yet global rates of LDKT have minimally increased, and there are disparities in access. The need for a systems approach to improvement has been highlighted.

Uncovering Xi Jinping's Policy Agenda: Text As Data Approach
The Developing Economies, Volume 63, Issue 1, Page 9-46, March 2025.How many agendas has Xi Jinping put forth and promoted since taking office in 2012, and what are the types of agendas? How much of political attention has each agenda received, and how has the allocation of attention changed over time? We utilize a dataset of presidential statements, speeches, and reports from 2012 to 2022 and employed automated text ...

Conservation Biology, Volume 39, Issue 1, February 2025.Abstract Trade restrictions are often advocated and implemented as measures to protect wild species threatened by overexploitation. However, in some instances, their efficacy has been questioned, notably by governments in the southern African (SADC) region, which tend to favor a sustainable use approach to wildlife management. We conducted a systematic

Guangtongxin yanjiu, 2014 通过对激光外调制不同方式的对比分析,重点研究了AOM（声光调制）器件的原理及控制方法,提出了三种可控调制方法,且在控制方面分别进行了对比验证。采用其中的TTL电平（典型值高电平3.5V,低电平0.2V）调控方法,将数字信号经FPGA（现场可编程门阵列）以2FSK（二进制移频键控）方式进行调制编码,调制信号通过AOM加载于激光上,激光通过自由空间传输,借助串口实现了通信速率为115.2kbit/s的数字通信,且该激光外调制通信系统高频载波达到了0.7MHz左右。

Politics &Policy, Volume 53, Issue 1, February 2025.ABSTRACT This article argues that the European biometric ID installations and securitization practices at West African borders harm African migrants and compromise the security goals of Europe and Africa. Using Niger's experience, I contend that migrants' poor adaption to the biometric border processes is closely connected to their identity conflicts ...
