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。

本文主要从四个因素研究了“建议……不”和“不……建议”两个句式是强化否定还是弱化否定:否定的直接性、否定的明确性与加工效率、否定的词汇手段和否定的词汇化。从共时平面看,这两个句式属于性质不同的句式,不宜从某个动因看否定强化问题,而应该全面地从多动因互动角度看待此问题。

2018年以来,美国针对中国新疆发起一波波舆论战,罗织的罪名令人匪夷所思。文本以政治媒介化理论观照美国涉疆舆论战。政治媒介化指在美西方市场逻辑作用下,政治逐渐依赖、内化媒介逻辑,政治过程受媒介逻辑长期形塑的现象。美国涉疆舆论战通过政治媒介化策略,将其遏制中国的目的隐蔽地转换为一个个“悲情故事”,妄图实现其舆论外交目的。文本深入剖析了美国涉疆舆论战中的政治媒介化过程与策略,揭露了美国涉疆舆论战的真相与本质。

近年来的研究认为肠道菌群可影响骨骼肌的质量和功能,并提出了“肠-肌轴”理论。随着世界人口老龄化的日趋严重,肌肉减少症越来越受到人们的关注,成为严重损害老年人健康的疾病之一。临床研究发现,肌肉减少症患者肠道菌群的多样性降低,有益菌显著减少,有害菌大量增加。调节肠道菌群可改善肌肉减少症患者的骨骼肌质量和功能。肠道菌群代谢产物,如氨基酸、脂多糖和短链脂肪酸等对骨骼肌蛋白质的代谢具有调控作用,通过多种途径调节骨骼肌蛋白质的合成与分解。因此,本文对肌肉减少症患者肠道菌群的变化及其代谢产物对骨骼肌蛋白质的调控作用进行综述,以期为肌肉减少症的临床治疗提供新的思路。

文章从媒介本体论视角探讨了城市传播领域的基本问题:城市空间作为媒介如何使传播得以可能?在传播过程中形成了何种交往关系?从城市起源来看,人们对于恐惧的规避和城市空间对浪漫主义的召唤为城市空间中社会关系的形成创造了可能;就城市发展而言,以现代性为标志的技术象征空间、蕴含特定意识形态的形式象征空间和以人本主义为中心的体验性空间构成了城市空间基本的话语体系,三者的博弈不断主导着城市的空间实践。其中,城市象征空间构造出的是不对称服膺关系,而体验性的城市空间促成了对称不确定关系。
