Identical Platform, Divergent Publics: Sweden and Finland During the 2022 NATO Crisis
Policy &Internet, Volume 18, Issue 3, September 2026.ABSTRACT Digital platforms are often theorized as universal drivers of political polarization, yet empirical patterns remain inconsistent across countries. Leveraging the natural‐experiment logic of Sweden's and Finland's simultaneous 2022 NATO applications and the NATO–Turkey diplomatic crisis, this study examines how national political cultures ...

How Do I Measure up? Social Influence and L2 Motivation in the Algorithmic Age
International Journal of Applied Linguistics, Volume 36, Issue 3, Page 1963-1974, August 2026.ABSTRACT Comparative thinking is a fundamental human drive and a hallmark of contemporary life. For social action, such as the learning and use of additional languages, a target for appraisal (an L2 attribute) is evaluated in relation to a comparison standard (an appraiser's standpoint).

He jishuγ辐射场的准确重构是实现辐射防护数字化的基础，也是进行辐射剂量评估与可视化仿真的前提。为了有效解决目前核设施现场由于高梯度非均匀辐射源项分布导致的三维γ辐射场重构偏差较大的切实问题，本文创新性地提出基于贝叶斯信息准则建立的非均匀源活度分布模型择优方法，并将最优模型用于三维γ辐射场的重构。结果表明：该方法在高活度梯度、高剂量率梯度情形下的辐射场重构准确度显著优于克里金插值方法；在核设施实际场景的三维辐射场重构案例中，测试集剂量率重构结果与实测值平均相对偏差仅为12.69%，低于克里金插值结果的85.40%。

大数据, 2023 近数据计算范式驱动了银行、券商在全国或全球范围内建设多个数据中心。在传统的业务模式中，事务聚焦单个数据中心的数据访问。随着业务模式的变化，跨数据中心的分布式事务成为常态，例如，银行账户之间的转账、游戏账户之间的装备交换等，而这些账户的数据存储在不同区域的数据中心上。分布式事务处理需要两阶段提交协议来保证各参与节点子事务提交的原子性。在跨空间域场景下，节点之间的网络时延更长且存在差异性，传统的事务处理技术需要拓展，以保证系统能够提供较高的吞吐量。在分析了跨域事务存在的问题和优化空间后 ...
