The Future of AI in the GCC Post‐NPM Landscape: A Comparative Analysis of Kuwait and the UAE
Politics &Policy, Volume 53, Issue 6, December 2025.ABSTRACT Comparative evidence of how two Gulf Cooperation Council (GCC) states translate artificial intelligence (AI) ambitions into post–New Public Management (post‐NPM) outcomes are scarce because most studies focus on Western democracies. To fill this gap, we examine constitutional, collective choice, and operational rules that shape AI uptake in ...

大数据, 2023 针对当前公益慈善行业存在的善款流向不透明、不可追溯和捐赠信息易篡改等问题，构建了一种基于联盟区块链的公益善款溯源系统模型。共识过程中应用了一种改进的PBFT共识算法——DG-PBFT算法，将原有的主节点随机选举改进为积分制选举，并将原来的三阶段共识优化为两阶段。溯源系统依托Hyperledger Fabric平台进行开发，采用Go语言进行链码开发。配置4个组织，分别对应捐助者、受助者、慈善机构和监管部门。根据功能需求设计智能合约，不仅实现了善款信息的溯源，还能通过该溯源系统进行申诉与监督。实验结果表明 ...

Ultrasound in Obstetrics &Gynecology, Volume 64, Issue 1, Page 36-43, July 2024.ABSTRACT Objective Although remarkable strides have been made in fetal medicine and the prenatal diagnosis of congenital heart disease, around 60% of newborns with isolated coarctation of the aorta (CoA) are not identified prior to birth. The prenatal detection of CoA has been shown to have a notable impact on survival rates of affected infants.

, 2019 基于区块链的智能合约对代码自治领域的私法存在的必要性与可能性提出了挑战。去中心化结构的不可追溯、不可修改、不可救济与自执行性,表面上是对法之权威的蔑视、对法之主权的挑衅,实则是以颠覆性的方式对法之信仰的坚持,对法之原则的恪守及对法之功能的维护。法应社会需求而生,私法对智能合约应当抱持开放与包容的态度,积极回应科技对传统法律思维的挑战,根据其物理与逻辑结构的分布特点,采用灵活与创新的应对策略将其纳入法域的视野。国家社会科学基金重大项目“社会主义核心价值观融入民法典编纂重大问题研究”（项目号 ...
