Unpacking Welfare Deservingness Theory: Evidence From the Perceived Deservingness of Gig Workers
Policy Studies Journal, EarlyView.ABSTRACT The theory of welfare deservingness provides valuable insights into the social legitimacy of welfare programs and the principles underlying policy design. In examining the question of who deserves what and why, established deservingness criteria emphasize that individuals demonstrating motivation to work (“reciprocity”) are typically perceived

Study and Design on Circuitry System of Fiber Optical Electronic Current Transformer [PDF]
, 2010 近几年对数字化变电站新技术的研究及应用成为热点，数字化变电站已在国内电力系统试点应用并取得一定经验。电力系统中传统的大电流传感器通常采用电磁互感技术，其具有反应速度慢、容易饱和、在高压下容易被击穿等缺点，正在被新型的电子式电流互感器所取代。电子式电流互感器具有反应速度快、采集精度高、耐高压、智能化、网络化等诸多优点，在国外的电力系统中已经获得了广泛应用，实现了电力系统的一次设备智能化、二次设备网络化、运行管理系统自动化、设备间相互可操作等功能，提高了电力系统的测量精度 ...

Emotion and the Advocacy Coalition Framework: An Affective Dynamics Perspective
Policy Studies Journal, EarlyView.ABSTRACT Despite extensive evidence that emotion and cognition are deeply intertwined, the Advocacy Coalition Framework (ACF) lacks an analytically independent emotional mechanism in its causal architecture—an omission that may be particularly consequential in policy subsystems structured around morally charged, identity‐laden policy disputes.

一种利用顶点位形描述的任意正交折线线圈阻抗解析建模新方法 [PDF]
, 2018 本文利用顶点位形描述方法,建立了任意正交折线线圈阻抗的封闭模型.首先,利用二阶矢量位公式对一个线形矩形线圈的电磁场分布进行描述,并推导了该矩形线圈的标量势表达式,其包含有一个利用矩形四个顶点的位置因子和角形因子进行描述的积分项;其次,证明了角形因子的两个重要性质,并利用该性质将矩形线圈的标量势表达式推广到任意正交折线线圈的情况;最后,建立了任意正交折线线圈阻抗的解析表达式,并以矩形螺线线圈为例进行了阻抗计算,并将计算结果与实验测量值进行了对比.结果表明,计算值与测量值之间有较好的吻合度 ...

Compliance in Regulatory Gray Areas: The Case of the Organic Seed Standard
Policy Studies Journal, EarlyView.ABSTRACT Adaptive regulations, designed to balance flexibility with accountability, can embed provisions that unintentionally leave room for firms to shirk on their responsibilities by exploiting flexibility. We call these provisions “regulatory gray areas,” and ask: how should we understand (non‐)compliance in adaptive regulatory settings?

Research on borehole transient electromagnetic positioning method of azimuthal coil scanning detection [PDF]
The borehole transient electromagnetic method is used to detect the long-range water-bearing bodies around the borehole wall by using the advanced water exploration borehole in the heading roadway, which avoids the “one’s opinion in one hole” because the

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.

Research on the Polarimetric All-Fiber Optical Current Sensor Based on the Faraday Effect [PDF]
, 2007 光学电流互感器（OCT）是新型的电流互感器，它克服了传统电流互感器的许多缺点，在电力系统中具有广阔的应用前景。本文在全面分析和总结OCT发展历史和现有技术水平的基础上，针对实用化要求，确定以光纤电流传感器为研究重点。 光纤因弯曲引入大量的线性双折射，这降低了光纤电流传感器的灵敏度，严重时甚至完全淹没法拉第磁光效应。本文采用退火光纤来做传感光纤，这样不但可以消除由于弯曲引入的线性双折射，还可以降低光纤内在线性双折射。针对反射式光纤电流传感器采用两种集成器件：一体化光纤起偏旋转器件（P-FR ...

World Water Policy, Volume 12, Issue 1, February 2026.ABSTRACT Water security in tropical regions faces escalating pressures from climate change, land‐use shifts, and population growth. We conducted a bibliometric review of 1146 peer‐reviewed articles (1964–2023) on tropical water security. Latent Dirichlet Allocation identified 13 thematic topics and their evolution. Publications rose sharply after 2012,
