随着现代风险社会及深度媒介化时代的到来,突发公共事件网络舆情风险往往由事件与传播双重逻辑耦合引发,常使国家陷入不确定性风险传播的被动响应中,因此需要建立突发公共事件网络舆情风险的现代化协同治理机制。在事件属性层面,应化解社会矛盾冲突、建立常态化社会治理机制,将数字技术作为提高舆情治理能力的基础设施,以社会治理现代化推动舆情风险治理的现代化;在媒介属性方面,要提高新型主流媒体突发公共事件舆论引导力,从舆情风险研判、预警及处置等层面进行全过程的舆情风险防范与治理。从整体性治理视角而言,建立网络舆情纵横协同应对,国家与社会、社会治理与传播治理的协同治理机制。通过现代化网络舆情风险协同治理机制的建立以提高国家应对突发公共事件网络舆情风险的韧性,适应中国式现代化国家治理的需要。

目的分析2011—2021年我国乙型病毒性肝炎的流行特征及时空聚集情况，为乙肝防控工作提供依据。方法通过《中国卫生健康统计年鉴》、中国疾病预防控制中心收集2011—2021年我国各地区乙肝发病情况数据，描述性分析乙肝流行趋势，通过空间自相关分析和时空扫描分析探究乙肝发病的全局与局部空间聚集性及时空聚集性。结果 2011—2021年，我国累计报告乙肝病例10 838 518例，乙肝年均发病率71.78/10万，该时段内乙肝发病下降趋势差异无统计学意义(Z=-1.557,P=0.120)。空间自相关结果显示，乙肝发病高—高聚集区有7个，以广东为主；乙肝发病低—低聚集区有3个，以上海、江苏为主。时空扫描结果表明，乙肝高发病聚集区在2011—2015年有2个，为西北地区，在2017—2021年有6个，转变为华南及其北部地区。乙肝低发病聚集区在2016—2021年有14个，主要分布在华东及东北地区。结论 2011—2021年，我国乙肝发病下降趋势不显著，乙肝发病存在空间及时空聚集性。未来，应加强高发地区的乙肝监测和防治资源配置。

We theoretically study the transmission spectrum of the cavity field in a double-cavity optomechanical system with cross-Kerr(CK) effect. The system consists of two tunneling coupling optomechanical cavities with a mechanical resonator as a coupling interface. By doping CK medium into the mechanical resonator, CK couplings between the cavity fields and the mechanical resonator are introduced. We investigate the effects of CK coupling strength on the transmission spectrum of the cavity field, including the transmission rate, nonreciprocity and four-wave mixing(FWM). We find that the transmission spectrum of the probe field can show two obvious transparent windows, which can be widened by increasing the CK coupling strength. For the transmission between the two cavity fields, the perfect nonreciprocity and reciprocity are present and modulated by CK coupling and phase difference between two effective optomechanical couplings. In addition, the effects of the optomechanical and CK couplings on FWM show that the single peak of FWM is split into three symmetrical peaks due to the introduction of the CK effect.
