The COVID-19 pandemic posed risks to the psychosocial development of children and adolescents in the digital age. Under such a background, this study aims to examine the effects of pandemic stress on cyberbullying perpetration and victimization among Chinese adolescents, and to explore the mediator of perceived safety and the moderator of family cohesion underlying this association, during China\'s outbreak of Omicron. A sample of 822 adolescents was obtained from Taizhou in Zhejiang Province, China, based on a multistage cluster random sampling method. The results showed that pandemic stress was positively associated with cyberbullying perpetration and victimization. Moreover, pandemic stress negatively predicted perceived safety, which in turn, increased the probability of cyberbullying perpetration and victimization. Furthermore, family cohesion moderated the effects of pandemic stress on cyberbullying perpetration and victimization. This study contributes to practical implications for policy making and social work practices regarding how to protect adolescents from cyberbullying during the pandemic.

This study examined how trust in the information about COVID-19 from social media and official media as well as how the information was disseminated affect public\'s wellbeing directly and indirectly through perceived safety over time.
Two online surveys were conducted in China, with the first survey (Time1, N = 22,718) being at the early stage of the pandemic outbreak and the second one (Time 2, N = 2,901) two and a half years later during the zero-COVID policy lockdown period. Key measured variables include trust in official media and social media, perceived rapid dissemination and transparency of COVID-19-related information, perceived safety, and emotional responses toward the pandemic. Data analysis includes descriptive statistical analysis, independent samples t-test, Pearson correlations, and structural equation modeling.
Trust in official media, perceived rapid dissemination and transparency of COVID-19-related information, perceived safety, as well as positive emotional response toward COVID-19 increased over time, while trust in social media and depressive response decreased over time. Trust in social media and official media played different roles in affecting public\'s wellbeing over time. Trust in social media was positively associated with depressive emotions and negatively associated with positive emotion directly and indirectly through decreased perceived safety at Time 1. However, the negative effect of trust in social media on public\'s wellbeing was largely decreased at Time 2. In contrast, trust in official media was linked to reduced depressive response and increased positive response directly and indirectly through perceived safety at both times. Rapid dissemination and transparency of COVID-19 information contributed to enhanced trust in official media at both times.
The findings highlight the important role of fostering public trust in official media through rapid dissemination and transparency of information in mitigating the negative impact of COVID-19 infodemic on public\'s wellbeing over time.

Whether the public feels psychologically safe about intelligent connected vehicles (ICVs) is crucial for this new technology to prevail. While researchers have realized the importance of perceived safety, a direct and psychometrically sound measure is still needed. This paper aimed to develop and validate a scale to measure the perceived safety of ICVs. In Study 1, an 8-item scale of the perceived safety was developed based on a literature review and used with a sample from Beijing (n = 373), among the people who are very likely to be the first wave of users. Exploratory factor analysis retained six items and found that a two-dimensional model (three items for cognitive safety and three items for emotional safety) best suited the data. Correlational analyses suggested that the two components may have unique causes and consequences. In Study 2, using a different sample from Shenzhen (n = 352), confirmatory factor analysis consolidated the two-factor model. Further correlational analyses showed that the scale had good criterion-related validity. Across two studies, cognitive safety was related to perceived controllability, the tendency to seek new technologies, ICV driving experience, perceived government support, drive intention and intention to be other road users. Emotional safety was correlated with social support, familiarity, benefit perception, purchase and recommend intention. These results suggest that the scale developed in this study is a useful and reliable tool to measure perceived safety. Implications for future studies and relevant policies are discussed.

China has a historic system of wide cycle tracks, many of which are now encroached by cars, buses and bus stops. Even with these conditions, college students still bicycle. On campuses, students park their bikes on facilities ranging from kick-stand-plazas to caged sheds with racks, pumps and an attendant. In other countries, including Canada, some of the newer cycle tracks need to be wider to accommodate an increasing number of bicyclists. Other countries will also need to improve their bike parking, which includes garage-basement cages and two-tiered racks. China could provide lessons about cycle tracks and bike parking. This study applied the Maslow Transportation Level of Service (LOS) theory, i.e., for cycle tracks and bike parking, only after the basic needs of safety and security are met for both vehicle occupants and bicyclists can the higher needs of convenience and comfort be met. With random clustering, a self-administered questionnaire was collected from 410 students in six dormitory buildings at Peking University in Beijing and an environmental scan of bicycle parking conducted in school/office and living areas. Cycle tracks (1 = very safe/5 = very unsafe) shared with moving cars were most unsafe (mean = 4.6), followed by sharing with parked cars (4.1) or bus stop users (4.1) (p < 0.001). Close to half thought campus bike parking lacked order. The most suggested parking facilities were sheds, security (guard or camera), bicycle racks and bicycle parking services (pumps, etc.). If parking were improved, three quarters indicated they would bicycle more. While caged sheds were preferred, in living areas with 1597 parked bikes, caged sheds were only 74.4% occupied. For the future of China\'s wide cycle tracks, perhaps a fence-separated bus lane beside a cycle track might be considered or, with China\'s recent increase in bike riding, shared bikes and E-bikes, perhaps cars/buses could be banned from the wide cycle tracks. In other countries, a widened cycle track entrance should deter cars. Everywhere, bike parking sheds could be built and redesigned with painted lines to offer more space and order, similar to car parking.
