The impact of COVID-19 prevention and control measures on residential burglary hotspots: A case study of the core urban areas of Beijing

In order to analyze the impact of COVID-19 prevention and control measures on the hotspots of residential burglary, the data of crimes that occurred during the First Level Response period of Major Public Health Emergencies in Beijing in 2020 and the same period in 2019 were collected, and the changes of hotspots during the two periods were compared by using kernel density estimation and predictive accuracy index. Consequently, the environmental features such as street network, point of interest (POI) diversity, crime locations, and repeat victimization in significantly varied hotspot areas were investigated. The results show that: 1) After the outbreak of the pandemic, the occurrence of residential burglary in the core urban areas of Beijing dropped significantly, and daily occurrence of crimes during the First Level Response period in 2020 decreased by 66.8% compared with the same days in 2019. 2) The eight major hotspots that existed in 2019 apparently declined during the corresponding days in 2020, five of them basically disappeared, and three hotspots weakened. 3) The declined hotspots were generally clustered around traffic hubs, areas with high diversity of POIs, clustered crimes, and repeat victimizations. 4) Home isolation and social restriction strategies implemented during the First Level Response period reduced the opportunities of offenders, and the real-name inspection adopted in public places increased the exposure risk of offenders, which are the main reasons for the hotspots decline during the pandemic. This work has some implications for crime prevention and police resources optimization during the pandemic. © 2023, Editorial office of PROGRESS IN GEOGRAPHY. All rights reserved.

Relationship between attentional Bias, anxiety, depression and post-traumatic stress disorder in primary and middle school students

Objective: To investigate the relationship between negative attentional bias and post-traumatic stress disorder(PTSD) in the context of higher depression and anxiety symptoms after the outbreak of COVID-19, so as to provide scientific basis for mental health education in primary and secondary schools. Methods: From March to April 2021, a total of 708 students from primary school and junior high school (grade 6 through grade 9) in Beijing, Shanxi, Hunan, Shandong, Hebei, Hubei of China were selected. The Children's Revised Impact of Event Scale(CRIES), the Attention to Positive and Negative Information Scale (APNI)and Depression, Anxiety and Stress Scale-21(DASS-21) were used in a questionnaire survey. Results: A total of 242 students were diagnosed with PTSD, and the detection rate was 34.2%. The scores of intrusion and high arousal of boys(7.92+or-5.33, 8.60+or-5.41) were lower than those of girls(8.72+or-4.85, 9.50+or-4.76), and the difference was statistically significant (t=-2.04, -2.32, P < 0.05). There were statistically significant differences of negative attention bias, CRIES score, intrusion, debarb and high arousal among primary and middle school students of different grades (F=3.57, 5.99, 4.45, 4.60, 7.40, P < 0.05). Negative attention bias, anxiety, depression and post-traumatic stress symptoms were significantly positively correlated (r=0.27-0.84, P < 0.05). Logistic regression analysis showed that anxiety (OR=1.13, 95%CI=1.06-1.20) and negative attention bias (OR=1.10, 95%CI=1.07-1.12) were positively associated with PTSD symptoms in primary and middle school students(P < 0.01). Conclusion: Anxiety and depressive symptoms show impacts on negative attention bias and might exacerbate the symptoms of post-traumatic stress disorder. Therefore, emotional adjustments can help reduce the post-traumatic stress response in the post-epidemic period.

Evaluation of adverse effects due to inactive COVID-19 vaccination in healthcare workers with or without a history of COVID-19

Objective: Vaccines are one of the promising approaches to control the pandemic. The aim of this study, which was conducted on healthcare workers who previously were or were not infected with COVID-19, was to evaluate the undesirable effects that developed after the CoronaVac (Sinovac Life Sciences, Beijing, China). Methods: Volunteers who were administered the first dose of inactivated CoronaVac vaccine between January 14-24, 2021, were included in this retrospective study. Demographic information was obtained from the questionnaire results and from the data of the applications made due to side effects. Results: 911 healthcare workers, 232 of whom had a history of COVID-19 were included in the study. The mean age of those with a history of COVID-19, was 36 (20-66), and 33.6% were men. 26.7% were doctors, 34.9% were nurses, 155 (66.8%) worked in internal and 62 (26.7%) in surgical units. There was no significant difference between the two groups regarding age, gender, task, and the departments they worked in. Comorbidities were present in 25.9% of the group with a history of COVID-19;the most common disease was asthma (5.6%). Allergy history was 4.3% in the group with COVID-19 and 7.8% in the other group (p=0.070). The incidence of post-vaccine adverse events (62.9%) was higher in those with a history of COVID-19 than in those without (57.1%). The most common adverse event was a headache, and it was significantly higher in the group who had COVID-19 compared to those who had not (36.6% vs. 27.7%;p=0.01). Conclusion: In our study, we observed that the rates of undesirable effects after vaccination were high in individuals with a history of COVID-19. Although it is thought that this situation may be related to the developing antibody response rates, the insufficient number of cases and the lack of determination of the antibody response after infection and vaccination are a disadvantage of the study.

GIS-Based Analysis of the Spatial Distribution and Influencing Factors of Traditional Villages in Hebei Province, China

Traditional villages are a valuable cultural asset that occupy an important position in Chinese traditional culture. This study focuses on 206 traditional villages in Hebei Province and aims to explore their spatial distribution characteristics and influencing factors using ArcGIS spatial analysis. The analysis shows that traditional villages in Hebei Province were distributed in clusters during different historical periods, and eventually formed three core clusters in Shijiazhuang, Zhangjiakou and Xingtai-Handan after different historical periods. Moreover, the overall distribution of traditional villages in Hebei Province is very uneven, with clear regional differences, and most of them are concentrated in the eastern foothills of the Taihang Mountains. To identify the factors influencing traditional villages, natural environmental factors, socio-economic factors, and historical and cultural factors are considered. The study finds that socio-economic and natural environmental factors alternate in the spatial distribution of traditional villages in Hebei Province. The influence of the interaction of these factors increases significantly, and socio-economic factors have a stronger influence on the spatial distribution. Specifically, the spatial distribution of traditional villages in Hebei Province is influenced by natural environmental factors, while socio-economic factors act as drivers of spatial distribution. Historical and cultural factors act as catalysts of spatial distribution, and policy directions are external forces of spatial distribution. Overall, this study provides valuable insights into the spatial distribution characteristics and influencing factors of traditional villages in Hebei Province, which can be used to develop effective strategies for rural revitalisation in China.

Natural Evolution of Porcine Epidemic Diarrhea Viruses Isolated from Maternally Immunized Piglets

Simple SummaryDuring the long-term co-evolution of the virus and the host, even closely related vaccines may emerge with incomplete protective immunity due to the mutations or deletions of amino acids at specific antigenic sites. The mutation of PEDV was accelerated by the recombination of different strains and the mutation of the strains adapting to the environment. These mutations either cause immune escape from conventional vaccines or affect the virulence of the virus. Therefore, researching and developing new vaccines with cross-protection through continuous monitoring, isolation and sequencing are important to determine whether their genetic characteristics are changed and to evaluate the protective efficacy of current vaccines. The porcine epidemic diarrhea virus (PEDV) can cause severe piglet diarrhea or death in some herds. Genetic recombination and mutation facilitate the continuous evolution of the virus (PEDV), posing a great challenge for the prevention and control of porcine epidemic diarrhea (PED). Disease materials of piglets with PEDV vaccination failure in some areas of Shanxi, Henan and Hebei provinces of China were collected and examined to understand the prevalence and evolutionary characteristics of PEDV in these areas. Forty-seven suspicious disease materials from different litters on different farms were tested by multiplex PCR and screened by hematoxylin-eosin staining and immunohistochemistry. PEDV showed a positivity rate of 42.6%, infecting the small and large intestine and mesenteric lymph node tissues. The isolated strains infected Vero, PK-15 and Marc-145 multihost cells and exhibited low viral titers in all three cell types, as indicated by their growth kinetic curves. Possible putative recombination events in the isolates were identified by RDP4.0 software. Sequencing and phylogenetic analysis showed that compared with the classical vaccine strain, PEDV SX6 contains new insertion and mutations in the S region and belongs to genotype GIIa. Meanwhile, ORF3 has the complete amino acid sequence with aa80 mutated wild strains, compared to vaccine strains CV777, AJ1102, AJ1102-R and LW/L. These results will contribute to the development of new PEDV vaccines based on prevalent wild strains for the prevention and control of PED in China.

Can Vaccine Development Be Safely Accelerated?

The three-dimensional (3-D) structure of the spike protein suggests that it binds more tightly to human cell surface receptors than SARS-CoV, a possible reason that this coronavirus exhibits greater infectivity (2). The Vaccine Research Center (VRC) of the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), collaborated with Moderna to design the vaccine. Moderna's mRNA vaccines can contain multiple mRNAs coding for different proteins and mimic natural infection, thus stimulating a more potent response, according to the company. Stabilizing the pre-fusion virus form A fourth group receiving funding from CEPI for application of a vaccine platform technology to accelerated development and manufacture of a COVID-19 vaccine is located at Australia's University of Queensland (UQ) School of Chemistry and Molecular Biosciences (7).

An intermestic approach to China's public diplomacy: a case study of Beijing's COVID-19 communication in the early stages

PurposeThe aim of this study was to examine the early stages of the COVID-19 outbreak and the international communication management of Chinese diplomats as a case for extending the definition of intermestic public diplomacy. The goal was to reveal how Beijing subtly used both domestic and foreign social media to organize a network for communication about COVID-19 and purposefully soften the highly centralized and hierarchical political propaganda of the Communist Party of China (CPC).Design/methodology/approachBased on the literature on digital public diplomacy, the authors applied the existing concept of intermestic to Chinese politics in order to demonstrate the digitalization of public diplomacy, along with its forms and strategies under an authoritarian regime. A hybrid methodology combining quantitative network analysis and qualitative discourse analysis permits examination of China's intermestic online communication network dynamics, shedding light on how such an intermestic practice promoted Chinese values and power to international publics in the early stages of the COVID-19 crisis.FindingsThe authors' findings extend the implications of intermestic public diplomacy from a democratic context to an authoritarian one. By analyzing the content of public diplomacy and para-diplomatic social media accounts in China and abroad at the beginning of the COVID-19 crisis, the authors outlined China's early crisis management, explaining its intermestic public diplomacy transmission modes and strategies. Moreover, the authors identified changes in the narrative strategies of Chinese diplomats and journalists during this process.Social implicationsThe findings of this study underline that Beijing established a narrative-making virtual communication structure for disseminating favorable Chinese strategic narratives and voices through differentiated communication on domestic and foreign social media platforms. Such intermestic communication strategies were particularly evident and even further weaponized by Beijing in its large-scale Wolf Warrior diplomacy in the spring of 2020. Thus, the study's findings help readers understand how China digitalized its public diplomacy, its digital communication patterns and strategies.Originality/valueOn the one hand, geopolitical uncertainty and the popularity of social media have contributed to the evolution of the intermestic model of public diplomacy. This model allows actors to coordinate homogenous and differentiated communication practices to deploy their influence. On the other hand, the authors did not examine how intermestic audiences perceive and receive public diplomacy practices. In future studies, scholars should measure the agenda-setting capacity of diplomatic actors by examining the effects of such intermestic communication efforts.

Countering Beijing's Media Manipulation

The Chinese Communist Party (CCP) has long sought to influence media coverage about China in other countries. Over the past decade, this campaign has accelerated, reaching new world regions and topics. This article examines how CCP-linked actors seek to manipulate foreign information environments in four key ways: disseminating propaganda, spreading disinformation, censoring critical coverage, and controlling the infrastructure used to convey news. This article considers which efforts have yielded gains for the regime, obstacles that Beijing has encountered, and the response of nongovernmental actors. It concludes by considering how to enhance democratic resilience to the covert and coercive dimensions of the CCP's global media influence.

An Examination of the Spatial Spillover Effects of Tourism Transportation on Sustainable Development from a Multiple-Indicator Cross-Perspective

Tourism is linked to multiple dimensions, such as the economy, society, and environment, and the relationships among its influencing factors are complex, diverse, and overlapping. This study constructed an evaluation index system to measure the degree of coordinated development of tourism, transportation, and the regional economy, then built a tourism-transportation-based Spatial Durbin Model (SDM) regarding the process of the coordinated development of tourism in the Beijing-Tianjin-Hebei region (BTHR) from 2010 to 2020. This paper explains the current status of sustainable tourism development in the BTHR and the impact and spillover effects of transportation on tourism development. The results show that the normalized tourism coordinated development index (NTCDI) of the BTHR increased from 13.61 in 2010 to 18.75 in 2019, then decreased to 14.45 in 2020. The results of SDM show that different transportation modes have different spillover effects on tourism. Specifically, civil aviation transportation has a positive impact and significant spillover on a city's tourism revenue (TR), while high-speed railway transportation has a negative spillover effect. The model results also show that the degree of openness of the city and city economic development level have significant positive effects and spillover effects on tourism development. Finally, the implications of related variables are discussed, and some suggestions are put forward on tourism development in the BTHR. However, there are some limitations in this study. In the future, international cooperation and data sharing will be strengthened, and multivariate methods such as social network analysis, artificial intelligence, and machine learning will be further integrated to achieve accurate simulation and prediction of the spatial spillover effects of tourism transportation.

China and Multilateral IP Governance

This chapter focuses on China's multilateral intellectual property engagement, and WIPO and WTO are the key forums of this analysis. The case of China's engagement with WIPO demonstrates various dimensions of reciprocity. In China's engagement with the WTO, it analyses China's early attempt at agenda-setting in its first and only proposal on IP in standardisation and China's position and involvement in the recent COVID-19-related IP waiver negotiations at the TRIPS Council. China's multilateral IP engagement reveals that it has taken the strategy of multi-forum engagement in navigating international IP regime complexity. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

China's Health Silk Road in the Middle East and North Africa amidst COVID-19 and a Contested World Order

The COVID-19 pandemic has offered China a unique opportunity for worldwide deployment of its longstanding health diplomacy, renamed the Health Silk Road (HSR), now an integral part of its Belt and Road Initiative. As a self-proclaimed South-South collaborator and developer,11Niall Duggan, ‘China's changing role in its all-weather friendship with Africa', In, Sebastian Harnisch, Sebastian Bersick, and Jörn-Carsten Gottwald (Eds). China's International Roles: Challenging or Supporting International Order? (Role Theory and International Relations) (London: Routledge, 2015), pp. 207-225..Beijing has assumed a leadership role, grounded in ‘moral realism', in the world's health governance. Beijing's health diplomacy has received acclaim in the Middle East and North Africa (MENA). However, the pandemic has exacerbated preexisting tensions between China, the United States (US) and European Union (EU). Western countries, wary of China's rising power, reacted resentfully, confirming underlying systemic rivalry. This article argues that the currently disputed, or shifting, world order accounts for the diametrically opposed reactions between the West and the MENA toward China's Health Silk Road.

Study of asymptomatic norovirus infection in kitchen workers in key places in Tongzhou district, Beijing, 2019-2021

Objective: To investigate the prevalence of asymptomatic norovirus infections status in kitchen workers in schools, child care settings, and catering service units and other key places in Tongzhou district of Beijing from 2019 to 2021, and provide evidence for scientific prevention and control of norovirus infection. Methods: The simple random sampling method was used to select the kitchen workers, especially the kitchen workers preparing cold dish, from catering service units, schools, childcare settings, construction sites, hotels as study subjects, and their anal swabs or stool samples were collected for norovirus nucleic acid detection by fluorescence quantitative PCR. Descriptive method was used to analyze the asymptomatic norovirus infection status of the kitchen workers. Results: A total of 3880 samples were collected from 552 units, and 15 norovirus positive cases were detected, including 1 sample positive for GI and 14 samples positive for GII. The asymptomatic norovirus infection rate was 0.39% (15/3880), in which 0.30% (5/1656) in man, and 0.45% (10/2224) in women. No asymptomatic infections were detected in age groups < 18 years and > 60 years, and 2055 cases were detected in age group 19- years, with a positive rate of 0.34% (7/2055), and 1637 cases were detected in age group 46- years, with a positive rate of 0.49% (8/1637). In 2019 when no COVID-19 epidemic occurred, the asymptomatic norovirus infection rate was 1.00% (1/100), but the asymptomatic norovirus infection rate was 0.39% (11/2805)in 2020 and 0.31%(3/975)in 2021 in the context of COVID-19 epidemic. Conclusion: The asymptomatic norovirus infection rate in kitchen workers in key places in Tongzhou was similar to the average level in Beijing during the same period. In COVID-19 epidemic period, the asymptomatic norovirus infection rate was lower than that before the epidemic.

2022 Beijing winter Olympic games: The effect of media visual primes on American public opinion about the Olympics and China

The 2022 Beijing Winter Olympics took place when American public opinion about China was already predominantly negative as media reports had a lot of highlights of human rights violations happening in China. Besides, earlier, the global image of China was undermined by the COVID-19 pandemic. In this study, we explored whether American public opinion about the Olympics and China can be influenced by images of the Olympics shared in the media. Findings from the 2 × 2 between-subject experimental design suggest that the opinions about the Olympics can be predicted by people's beliefs about China's role in the global pandemic. In addition to that, our findings suggest that pre-existing opinions and feelings held by most of the population can mitigate the effects of visual primes. © The Author(s) 2023.

Awareness towards COVID-19 prevention and factors related to the willingness to receive COVID-19 vaccine among people living with HIV/AIDS

Objective: To understand the awareness level towards coronavirus disease 2019(COVID-19) prevention and the willingness to receive COVID-19 vaccine among people living with HIV/AIDS, and to discuss the related factors. Methods: A questionnaire survey was conducted among people living with HIV/AIDS who visited the HIV clinic in the PLA General Hospital from June to December 2021.A general descriptive analysis, univariate and binary logistic regression analysis were performed to analyze data. Results: A total of 169 questionnaires were analyzed. Among them, 93.5%(158/169) would like to know more about COVID-19 related knowledge, 88.2%(149/169) were reminded to inject vaccine, 98.8%(167/169) would be far away from medium and high risk areas, 97.0%(164/169) would persuade others to follow the disease preventive requirements, 14.2%(24/169) thought that the propaganda was exaggerated, 30.8%(52/169) were worried about the safety of the vaccine, 80.5%(136/169) thought that they would feel relieved after the vaccination, and 98.2%(166/169) agreed that vaccination was the most effective way to fight against COVID-19. However, only 60.4%(102/169) were willing to receive COVID-19 vaccine. The major factors affecting vaccination intention were age and feeling safe after vaccination. Conclusions: People living with HIV/AIDS are more cautious about COVID-19 vaccination, therefore the coverage rate is relatively low.It is necessary for health providers to understand the specific situation of people living with HIV, and to enhance the heath education on the safety of COVID-19 vaccine especially among people with HIV/AIDS in order to improve the willingness to receive COVID-19 vaccine.

Online Teaching for Elementary and Secondary Schools During COVID-19

Examining these data, this report elucidates and partially compares the status quo, attitudes, difficulties, and needs among school principals and frontline teachers in elementary and secondary schools during the COVID-19 response effort of "suspending classes without suspending teaching and learning.” Status quo of the adoption of online teaching in elementary and secondary schools Understanding the status quo of the adoption of online teaching and teachers' relevant work experiences is integral to the effectiveness of "suspending classes without suspending teaching and learning.” According to the results (Figure 2), 28.2% of the surveyed teachers selected online interactive Q&A as their preferred online teaching activity, followed by webcasting/video on demand (27.5%) and live streaming (26.7%). [...]a survey was conducted on the provision of training by schools and teachers' participation in training offered by the superior education department over the last 3 years.

Phantom Sounds, Haunting Images

Powerful, imaginative, and long-lasting, the half-year mobilisation and its iconography are hard to forget, and the ongoing political crackdown keeps our memory alive with constant republications of photographs and video clips of the events. Since the outbreak of the Covid-19 pandemic and the proclamation of the National Security Law (NSL) on 30 June 2020, protests have, however, almost disappeared from Hong Kong's public spaces. [...]many films, books, and artworks have vanished from screening venues, shops, and libraries. Soon after the end of the movement, two anonymous books documented these ephemeral displays challenging authorities and urban order (Abaddon 2020;Guardian of Hong Kong 2020). [...]in October 2021, the Film Censorship Ordinance was amended to align with the NSL (Ho 2021b).

Study on Spatial Changes in PM2.5 before and after the COVID-19 Pandemic in Southwest China

Coronavirus disease 2019 (COVID-19) swept the world at the beginning of 2020, and strict activity control measures were adopted in China's concentrated and local outbreak areas, which led to social shutdown. This study was conducted in southwest China from 2019 to 2021, and was divided into the year before COVID-19 (2019), the year of COVID-19 outbreak (2020), and the year of normalization of COVID-19 prevention and control (2021). A geographically and temporally weighted regression (GTWR) model was used to invert the spatial distribution of PM2.5 by combining PM2.5 on-site monitoring data and related driving factors. At the same time, a multiple linear regression (MLR) model was constructed for comparison with the GTWR model. The results showed that: (1) The inversion accuracy of the GTWR model was higher than that of the MLR model. In comparison with the commonly used PM2.5 datasets "CHAP” and "ACAG”, PM2.5 inverted by the GTWR model had higher data accuracy in southwest China. (2) The average PM2.5 concentrations in the entire southwest region were 32.1, 26.5, and 28.6 μg/m3 over the three years, indicating that the society stopped production and work and the atmospheric PM2.5 concentration reduced when the pandemic control was highest in 2020. (3) The winter and spring of 2020 were the relatively strict periods for pandemic control when the PM2.5 concentration showed the most significant drop. In the same period of 2021, the degree of control was weakened, and the PM2.5 concentration showed an upward trend.

Interpretation of guidelines for medical observation management of close contacts with COVID-19 cases part 3: home-based medical observation

Effectively blocking the transmission route of coronavirus and protecting the susceptible population play significant roles in the control of COVID-19 pandemic. Strengthening home-based medical observation is one of the key points in preventing the spread of SARS-CoV-2 virus in families and communities. Therefore, in order to meet the needs for COVID-19 prevention and control in Beijing, a group of experts organized by Beijing Association of Preventive Medicine developed the Guidelines for medical observation management of close contacts with COVID-19 cases Part 3: home-based medical observation(T/BPMA007.3-2020), which offers the specific provisions for close contacts of COVID-19 cases who need home-based medical observation as well as home environmental condition, prevention and control requirements, waste disposal, disinfection, community prevention and control work requirements, basic requirements for training and education and management guidelines.It provides standard support for home-based medical observation of close contacts with COVID-19 cases.

Chinese Anti-Westernism on Social Media

The Chinese Communist Party and its supporters are increasingly using social media platforms to shape China's public image. This online image is a means of strengthening domestic nationalism and of projecting "soft power” abroad. This paper examines various forms of anti-Westernism that are central to this image-making. It analyzes several recent topics—the Belt and Road Initiative, climate change, the COVID-19 vaccine, the Beijing Olympics, and the conflict in Ukraine—on the r/Sino subreddit page of Reddit and compares them with two online news outlets, the South China Morning Post and China Daily. The paper focuses on how these media frame the contest between a rising China and a failing West, so creating a discourse that competes with the negative portrayals of China outside the country. The paper contrasts the aggressive strengthening of China's image against the West on social media with more sober accounts of the same topics in China's official media and in commercial news outlets. The contribution of the paper is to document an emerging online anti-Westernism that is playing an increasing role in the changing geopolitical landscape. © The Author(s) 2023.
