Research on Methods of Modeling and Fault Diagnosis for Micro Direct-Current Motors [PDF]
, 2015 直流微电机以体积小、重量轻、便于控制等优点被广泛应用于生产消费领域，在微型精密仪器中尤为重要。为了保证产品出厂品质，生产过程必须对直流微电机进行100%检测。目前检测主要依靠人工的经验来判断电机的好坏，其工作量大，生产效率低，漏检现象严重，导致电机出厂质量不稳定。因此有必要寻找一种简便和可靠的直流微电机在生产线上的故障检测技术。该技术即可以对出厂前的直流微电机进行自动在线检测，以保证直流微电机的出厂合格率；又可以推广应用于其他永磁直流电机的故障检测与诊断。 通过分析空载下直流电机的动态数学模型 ...

Responsibility as Principle: Crisis Management in Sweden, Norway, and Denmark Before COVID‐19
Risk, Hazards &Crisis in Public Policy, Volume 16, Issue 4, December 2025.ABSTRACT Following COVID‐19, the responsibility principle guiding emergency preparedness and crisis management in Scandinavian countries has once again faced criticism. In order to make sense of the current discussions surrounding this principle, this study uses Bacchi's framework of “What's the problem represented to be” to explore its development and

World Medical &Health Policy, Volume 17, Issue 4, Page 898-911, December 2025.ABSTRACT Policymakers organize and frequently communicate safety net policies, such as eligibility guidelines around administrative categories. The potential effects on how these thresholds are communicated remain empirically unexplored. We examined if communication either in terms of the Federal Poverty Line (FPL)‐ or dollar‐form alters preferences ...

A new beef: An analysis of discourse coalitions in the nascent cellular agriculture policy subsystem
Review of Policy Research, Volume 42, Issue 6, Page 1404-1427, November 2025.Abstract A robust approach to examining the nature and influence of coalitions in the policy process is the Advocacy Coalition Framework (ACF), which is especially useful to study policy issues fraught with scientific and technical controversy. Yet, important gaps exist in ACF literature regarding nascent policy subsystems. Consequently, there is scant

Research On Tax Inspection Based On Tax Compliance Objectives [PDF]
, 2015 在现代税收征管模式中，促进税收遵从和强化税务稽查是不可分割的一个整体，税务稽查对于提高税收遵从具有不可替代的作用。从实践来看，目前我国税务稽查更侧重收入职能，而稽查查补收入任务完成情况也成为衡量税务稽查工作是否有效的最重要标准，这种片面追求查补收入及入库数额的错误导向，必然造成税务稽查部门一切工作围绕组织收入进行，更容易对少数财务健全的上市公司及重点税源企业多头重复检查，而忽视对大量账薄混乱的中小企业检查，严重弱化了税务稽查的监控职能和惩戒职能，不利于税收遵从度提高。因此 ...

Journal of Linguistic Anthropology, Volume 35, Issue 2, August 2025.Abstract This article argues that social actors' media ideologies about digital interfaces are key to the enregisterment of online activities. Focusing on an online register emergent from user activities around Year, Hare, Affair (YHA)—a state‐aligned Chinese animation—I explore how different metadiscourses evaluate this register by entextualizing ...

Trump, Personalism, and US Administrative Capacity
Politics &Policy, Volume 53, Issue 4, August 2025.ABSTRACT Donald Trump represents an extraordinary degree of personalism in American politics, especially given the traditional power and capacity of the Republican Party and American democracy. A lesson Trump drew from his first term in office is that he needed to better institutionalize mechanisms of personal loyalty to deal with perceived betrayals ...
