四川大学学报. 自然科学版, 2014 冲突证据合成作为研究热点,由于发现Dempster-Shafer合成可能导致悖论,至今仍然没有统一的解决方法.本文提出了一种新的冲突证据合成方法.融合系统中各证据的重要程度可能不同,新方法首先通过融合多证据距离,从而可以更加准确地得到证据距离,进一步通过相关算法转化证据距离为证据权值,权值反映了证据的重要程度,根据权值,对原始的基本可信度分配函数进行重新分配,再通过改进的合成公式,对重新概率分配的证据进行合成,得到合成结果.通过具体的算例比较,说明新方法在合成冲突证据方面具有一定的优越性.

Dianci bileiqi, 2020 为了对瓷质绝缘子进行非接触式快速无损检测,提出一种基于微波透射法的绝缘子劣化检测方法。该方法根据介质中均匀平面波传输理论,对微波在绝缘子内部及交界面的传播过程进行分析。通过将绝缘子复杂结构简化成均匀介质层,建立了微波在绝缘子内部及交界面传输过程的数学模型。利用矢量网络分析仪和毫米波天线搭建了微波检测平台,对从现场取回的绝缘子样本进行对比实验。所实测的散射参量S21幅值差异的最大值达到16 d B以上,灵敏度较高,初步证明了微波透射方法应用于瓷质绝缘子劣化检测的可行性。

Out of Sight, Out of Mind? The Impact of Issue Proximity on Policy Choice at the Individual Level
Review of Policy Research, Volume 43, Issue 5, September 2026.ABSTRACT Scholars have extensively studied the link between issue definition and policy choice. However, empirical evidence on the role of issue proximity on policy support at the individual level remains scarce. The study draws on policy and management literatures to examine whether framing an issue as more or less spatially proximate to an individual

, 2006 刑事诉讼中关于非法证据的效力问题,不仅是一个重要的刑事证据理论问题,而且还是一个严肃的司法实践问题,关系到司法机关的公正形象,也关系到人权保障及控制犯罪的均衡选择。制约非法证据效力的因素是多方面的,各国的相关立法和理论也不尽一致。在我国,立法上对非法证据持否定态度,但对非法证据的效力尚无明确规定,理论界亦形成了多种主张和观点。因此,必须完善有关立法 ...

World Water Policy, Volume 12, Issue 3, August 2026.ABSTRACT In Ghana, the government has initiated a reform in rural water management to shift away from community‐based management (CBM) to state management, but research assessing the reform is still insufficient. This study aims to critically evaluate the impact of the reform in addressing rural water challenges.
