Utilizing national migration data regarding the outbreak of the novel coronavirus (2019-nCoV), this paper employs a difference-in-differences approach to empirically analyze the relationship between human mobility and the transmission of infectious diseases in China. We show that national human mobility restrictions ascribed to the first-level public health emergency response policy effectively reduce both intercity and intracity migration intensities, thus leading to a declining scale of human mobility, which improves the effectiveness in controlling the epidemic. Human mobility restrictions have greater influences on cities with better economic development, denser populations, or larger passenger volumes. Moreover, mobility restriction measures are found to be better implemented in regions with increased public awareness, or with provincial leaders who have healthcare crisis management experience, local administrative experience, or the opportunity to serve a consecutive term.
Although much is known about peer victimization, the majority of the longitudinal research in this area has been restricted to Western settings. The main objective of this study was to examine the interpersonal (rejection) and personal (withdrawal, aggression) antecedents and consequences of victimization for Chinese children living in Hong Kong. A sample of 1,058 children (501 boys; M age = 9.5 years) in Hong Kong was followed longitudinally from the 3rd and 4th grades to the 7th and 8th grades. Consistent with a transactional framework, rejection and withdrawal contributed to, as well as resulted from, victimization. Although victimization predicted later aggression, aggression was unrelated to later victimization. These findings closely replicate past research conducted in North America and European settings, and suggest considerable correspondence in the links between maladaptive child characteristics and victimization across Western and Hong Kong schools. 相似文献
