2020年新冠肺炎疫情冲击美国社会，凸显了美国公共卫生治理的困境。受新冠肺炎疫情影响，美国经济陷入深度衰退，全年经济大幅波动。大选年政治博弈加剧，分裂、对抗与斗争始终都是2020年美国国内政治和社会运行的主旋律。国内矛盾进一步加剧，社会权力面临特权化、碎片化、非理性化三重困境，多股思潮相互对冲，严重扰乱社会秩序，美国宪政体制面临多重挑战。美国外交呈现“双层博弈”特点，国内政治因素对美国外交政策的影响凸显。特朗普政府通过挑起国际争端来转移国内矛盾，同时利用“外交胜利”助推国内选情。展望未来，2021年美国经济摆脱衰退的可能性较大，但由于结构性问题复苏幅度有限。美国政治僵局持续，“特朗普主义”将会继续影响美国政治。防疫机制改革迫在眉睫，科学抗疫、合作抗疫重归主导。拜登团队执政后将适度回归自由国际主义路线，推行多边主义外交，力图发挥美国的主导作用。

A baby monitor is an electronic device that transmits sound and video-related activities of a baby to a receiver that is usually at the parents’ end. The basic version of a baby monitor consists of a radio transmitter that relays sound to the receiver. The receiver contains an inbuilt speaker that enables sound transmission between the baby and parents. This basic version of the baby monitor works within a short or limited range of transmission area. Technological advancements have led to the embedment of advanced features in baby monitors that keep parents updated and connected with their babies, even from a remote location. Vendors have integrated baby monitors with the latest technologies such as video transmission, Wi-Fi, and Bluetooth connectivity, to connect them with smartphones and to provide parents with continuous inputs of the baby’s activities. This, in turn, has paved the way for the growth of smart baby monitors with enhanced features for modern-day working parents.
