Unlike in developed countries, most public toilets in China do not provide toilet paper onsite and users must bring their toilet paper. Moreover, an open waste bin is placed in each user's cubicle to collect used toilet paper and tissues. Such practices, which are common in East Asia and central America, have induced a dilemma of toilet paper disposal because some municipalities have removed waste bins from public toilets to prevent virus transmission by fecal matter. As a consequence, users were forced to flush down their used toilet paper and tissues. Yet, it is unknown whether standard toilet paper can be flushed easily without causing issues in sewer operations. Here, we surveyed the conditions of toilets in university campus and other public facilities in different regions across China. We also evaluated the disintegration characteristics of toilet paper products both by conducting online surveys and by physical disintegration experiments. We found that only 15% of toilets provided toilet paper, while open waste bins occurred at nearly all sites. Further, our survey indicated that 82% of toilet paper products sold in China did not give any indication on their flushability, whereas 77% of US products did. Disintegration results showed that none of the five popular, best-selling toilet paper products passed the flushability standard. We propose strategies to solve the current toilet paper dilemma in developing communities. [ABSTRACT FROM AUTHOR]

The impact of COVID‐19 has underlined the need for reliable information to guide clinical practice and policy. This urgency has to be balanced against disruption to journal handling capacity and the continued need to ensure scientific rigour. We examined the reporting quality of highly disseminated COVID‐19 research papers using a bibliometric analysis examining reporting quality and risk of bias (RoB) amongst 250 top scoring Altmetric Attention Score (AAS) COVID‐19 research papers between January and April 2020. Method‐specific RoB tools were used to assess quality. After exclusions, 84 studies from 44 journals were included. Forty‐three (51%) were case series/studies, and only one was an randomized controlled trial. Most authors were from institutions based in China (n = 44, 52%). The median AAS and impact factor was 2015 (interquartile range [IQR] 1,105–4,051.5) and 12.8 (IQR 5–44.2) respectively. Nine studies (11%) utilized a formal reporting framework, 62 (74%) included a funding statement, and 41 (49%) were at high RoB. This review of the most widely disseminated COVID‐19 studies highlights a preponderance of low‐quality case series with few research papers adhering to good standards of reporting. It emphasizes the need for cautious interpretation of research and the increasingly vital responsibility that journals have in ensuring high‐quality publications. [ABSTRACT FROM AUTHOR]

Coronavirus disease 2019 (COVID-19) first emerged in China in November 2019. Most governments have responded to the COVID-19 pandemic by imposing a lockdown. Some evidence suggests that a period of isolation might have led to a spike in alcohol misuse, and in the case of patients with alcohol use disorder (AUD), social isolation can favour lapse and relapse. The aim of our position paper is to provide specialists in the alcohol addiction field, in psychopharmacology, gastroenterology and in internal medicine, with appropriate tools to better manage patients with AUD and COVID-19,considering some important topics: (a) the susceptibility of AUD patients to infection; (b) the pharmacological interaction between medications used to treat AUD and to treat COVID-19; (c) the reorganization of the Centre for Alcohol Addiction Treatment for the management of AUD patients in the COVID-19 era (group activities, telemedicine, outpatients treatment, alcohol-related liver disease and liver transplantation, collecting samples); (d) AUD and SARS-CoV-2 vaccination. Telemedicine/telehealth will undoubtedly be useful/practical tools even though it remains at an elementary level; the contribution of the family and of caregivers in the management of AUD patients will play a significant role; the multidisciplinary intervention involving experts in the treatment of AUD with specialists in the treatment of COVID-19 disease will need implementation. Thus, the COVID-19 pandemic is rapidly leading addiction specialists towards a new governance scenario of AUD, which necessarily needs an in-depth reconsideration, focusing attention on a safe approach in combination with the efficacy of treatment.

Aim: To explore the health beliefs of clinical and academic nurses from Japan, Australia and China regarding wearing paper masks to protect themselves and others, and to identify differences in participants' health beliefs regarding masks. Background: The correct use of face masks and consensus among health professionals across the globe is essential for containing pandemics, and nurses need to act according to policy to protect themselves, educate the public and preserve resources for frontline health workers. Paper masks are worn by health professionals and the general public to avoid the transmission of respiratory infections, such as COVID‐19, but there appear to be differences in health beliefs of nurses within and between countries regarding these. Methods: This qualitative descriptive study used content analysis with a framework approach. Findings: There were major differences in nurse participants' beliefs between and within countries, including how nurses use paper masks and their understanding of their efficacy. In addition, there were cultural differences in the way that nurses use masks in their daily lives and nursing practice contexts. Conclusion: Nurses from different working environments, countries and areas of practice hold a variety of health beliefs about mask wearing at the personal and professional level. Implications for nursing policy and health policy: The COVID‐19 pandemic has sparked much discussion about the critical importance of masks for the safety of health professionals, and there has been considerable discussion and disagreement about health policies regarding mask use by the general public. Improper use of masks may have a role in creating mask shortages or transmitting infections. An evidence‐based global policy on mask use for respiratory illnesses for health professionals, including nurses, and the general public needs to be adopted and supported by a wide‐reaching education campaign.

According to a recent World Health Organization estimate, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, which originated in China in 2019, has spread globally, infecting nearly 100 million people worldwide by January 2021. Patients with chronic liver diseases (CLD), particularly cirrhosis, hepatobiliary malignancies, candidates for liver transplantation, and immunosuppressed individuals after liver transplantation appear to be at increased risk of infections in general, which in turn translates into increased mortality. This is also the case for SARS-CoV-2 infection, where patients with cirrhosis, in particular, are at high risk of a severe COVID-19 course. Therefore, vaccination against various pathogens including SARS-CoV-2, administered as early as possible in patients with CLD, is an important protective measure. However, due to impaired immune responses in these patients, the immediate and long-term protective response through immunisation may be incomplete. The current SARS-CoV-2 pandemic has led to the exceptionally fast development of several vaccine candidates. A small number of these SARS-CoV-2 vaccine candidates have already undergone phase III, placebo-controlled, clinical trials in healthy individuals with proof of short-term safety, immunogenicity and efficacy. However, although regulatory agencies in the US and Europe have already approved some of these vaccines for clinical use, information on immunogenicity, duration of protection and long-term safety in patients with CLD, cirrhosis, hepatobiliary cancer and liver transplant recipients has yet to be generated. This review summarises the data on vaccine safety, immunogenicity, and efficacy in this patient population in general and discusses the implications of this knowledge on the introduction of the new SARS-CoV-2 vaccines.

The three challenges with the greatest bearing on Australia's security and prosperity each came to a head in 2020, viz. climate change; a novel coronavirus pandemic; and China. The world has become poorer, more dangerous and more disorderly. As we emerge from this crisis year, Australia's ability to project itself globally will start with its strength and vitality at home. Its favourable geography gives it the potential to become a leader in renewables. Given our geopolitical challenges, this is a strategic imperative. Yet, for now, the gap between reality and expectations has never been greater. [ABSTRACT FROM AUTHOR]

Pandemics always create dreadful effects not only on human life but also drastically influence businesses and industries. Historical evidence has apparently indicated that the outbreak of Spanish flu, SARS, MERS, and Ebola viruses, all created radical impacts on businesses around the globe, leaving behind the economic structures into miseries and deprivations. Similar is the case of COVID-19 outbreak which instigated from China and dispersed all over the globe. In Pakistan, the first case was reported in March 2020 and since then the government has relentlessly tried to impose lockdown and social distancing in order to avert the harm. It has been substantiated that the public isolations and lockdowns have not only yielded negative impacts on the economy but also on different forms of business and employment. Therefore, this study is aimed to analyze potential impacts of COVID-19 on different forms of industries in Pakistan through gathering the public opinion as the source of data. The study is one of the preliminary studies therefore it is based on descriptive design in order to show perceived impact of outbreak of virus. Results indicated that the pandemic is harmful and affecting most of the business in negative manner however there are some businesses which are burgeoning on opportunities emerged from the pandemic and attaining growth due to the spread of the virus.

Introduction: The epidemic of viral respiratory diseases in the last 20 years has affected many people around the world. In these situations, telemedicine may reduce unnecessary contacts and the risk of exposure to infection. This study aimed to review the papers performed to manage viral respiratory disease epidemics using telemedicine. Material and Methods: The PubMed and Scopus databases were searched in May 2020 for this systematic review study. Data were extracted from the final included papers based on the author, country, type of epidemic, telemedicine modality, telecommunication method, objective, participants, clinical outcome, cost, and satisfaction. Descriptive statistics were used to analyze data. Results: From 365 retrieved papers, 18 papers were included. Most of the papers were done in the US and China (67%). Half of the papers were done during the COVID-19 pandemic. Real-time modality was used in 78% of the papers. The telecommunication method in half of the papers was internetbased. Patients’ management and treatment was the main objective of the six papers. In 81% of the teleconsultation papers, the consultation was performed between patients and healthcare providers. The clinical outcome of all papers showed that telemedicine was successful in the management of viral respiratory disease epidemics. Cost and satisfaction outcomes were considered in a few papers. Conclusion: There is considerable evidence to show that telemedicine is a useful and convenient method to manage and control viral respiratory disease epidemics. Therefore, countries should pay special attention to telemedicine to control the current pandemic and future epidemics and use it extensively. [ABSTRACT FROM AUTHOR]

In this review paper efforts are made to present the Impact of COVID-19 on various economic activities like production, consumption and distribution. This is known to everyone that COVID-19 (Corona Virus Disease) spreadout in December 2019 from Wuhan in China and effected a lot of countries resulting in death of many. Therefore, to minimise the risk, many countries opted lockdown as a precaution to control its spread which effected the lives of ordinary people as well as the economy as a whole, GDP, Functions of Economy and a lot of activities were effected very badly. It had a huge impact on the consumption pattern of population as well as supply chains and production of various goods and services were also impacted as transportation was at halt and movement of people, products, services etc. was not possible from one place to another. There was a heavy down in employment, production, distribution and other activities as well. Hence, this paper will help the readers know the collective impact along with the sector wise effect of COVID-19 on various economic activities. For better understanding we have taken three major economic activities that is Production, Consumption and distribution. Along with these the basic introduction of COVID-19, lockdown and its impact on economy is stated. [ABSTRACT FROM AUTHOR]

The year 2020 was the beginning of the Covid-19 pandemic, and the turning point for the industries poorly affected by the unexpected conditions. This paper focused on the impact of a range of factors on China's exports of metal manufacture in 2020, in particular the impact of the COVID-19 pandemic on it. Using cross-sectional data, the paper collected relevant data for 151 countries in 2020. We applied trade gravity model by considering important parameters impacting on China's exports of metal manufacture such as GDP, distance, population, the total number of cases of COVID-19, employment rate, economic degrees of freedom, the political environment and the free trade agreement between China and other countries. Then, by collecting the data set for 2021, this paper compares the models for 2020 and 2021 with the aim of making a comparison of the impact of the pandemic on China's exports of metal manufactures. We also do some analysis about the trend of the effect of COVID-19 in the future. The paper continues with calculation of China's export potential for metal manufacture for its 151 partner countries including 54 of them are at the Trade Potential Untapped level, 38 at the Trade Potential Growing level and 59 at the Trade Potential Mature level based on gravity model. This paper also offers different detailed trade policies for the distinct levels of trade potential in the light of the impact of the COVID-19. [ABSTRACT FROM AUTHOR]

In the face of complex and changeable uncertain environments, corporate resilience is the crucial foundation for survival and sustainable development, and enhancing corporate resilience becomes an important goal for governments. In this context, this paper investigates the impact of government subsidies, as a typical government tool, on corporate resilience in crises. Based on the panel data of 2315 listed companies in China Shanghai and Shenzhen A-share market during the COVID-19 pandemic, this paper finds that: (1) government subsidies received before and during the crises can both enhance corporate resilience in crises. (2) Government subsidies enhance corporate resilience by alleviating financial constraints and boosting confidence. (3) The crises improve the efficiency of subsidies used by corporates, resulting in the enhancement of subsidies received during the crises being more pronounced than those received before the crises. This paper deepens the understanding of government subsidies' roles in crises, enriches the literature on government subsidies and corporate resilience, and provides a reference for improving government subsidies policy and enhancing corporate resilience. The government should increase government subsidies to mitigate the negative impact of uncertainty shocks on corporates and improve corporates' ability to respond to risks, and pay attention to the timing of subsidies to maximize the efficiency of government subsidies at the same time.

Thirdly, the paper will discuss the similarities and differences between the three doctrines. In the second part of this paper, the paper will discuss how the three doctrines apply to commercial lease cases in the context of COVID-19. The paper will select two commercial lease cases in New Zealand and China to analyse the robustness of all three legal doctrines in providing practical workable solutions for tenants and landlords during government-imposed lockdowns and enforced closures of leased premises. The paper illustrates how the differences in the legal tests, legal consequences and underlying rationales of the doctrines result in different outcomes of a case. The paper concludes that the doctrines each have their strengths and weaknesses and other civil and common law countries can learn from the experiences of China and New Zealand. Furthermore, the paper suggests that courts should carefully consider the relevant facts and circumstances of a case when applying legal doctrines. Moreover, courts need to strike the right balance between doing the victims of unforeseen circumstances and upholding the principle of the sanctity of contract. The analysis of the three doctrines is particularly useful in this day and age where there is a high likelihood of the occurrence of another pandemic-level event and causing unprecedented disruptions to the commercial world. Moreover, the research has provided tenants and landlords with a good starting point as to how to protect themselves in the event of an unforeseen event. [ABSTRACT FROM AUTHOR]

During the last three years, numerous research papers have been reported which use social media data to explore several issues related to the COVID-19 pandemic. Bibliometric methods in this work are used to analyze 1427 peer-reviewed documents from the last three years extracted from the Web of Science database. The results of this study show that there was high growth in publications in open access journals with an annual rate reaching 19.3% and they also identify the top cited journals and research papers. The thematic analysis of papers shows that research topics related to social media for surveillance and monitoring of public attitudes and perceptions, mental health, misinformation, and fake news are important and well-developed, whereas topics related to distance-learning education with social media are emerging. The results also show that the USA, China, and the UK have published many papers and received a high number of citations because of their strong international collaboration. [ABSTRACT FROM AUTHOR]

The financial market and regional innovation have been severely affected by the COVID-19 pandemic. This paper investigates the impact of financial support on regional innovation at different stages of the COVID-19 pandemic from 2019 to 2021 in China. Before the pandemic, bank support positively influenced regional innovation quantity and quality, while government support had a positive effect on quantity. Throughout COVID-19, both types of support promoted regional innovation quantity and quality. In the post-pandemic era, bank support had a modest positive impact on quantity, while government support influenced both quantity and quality. Evidences from other countries support these findings. The study guides decision-makers to mitigate the pandemic's impact on regional innovation with specific guidance for government and banking institutions. [ABSTRACT FROM AUTHOR]

Background: Residents' adoption of preventive behaviours proved beneficial in preventing the large-scale transmission of the virus during the early stages of the COVID-19 outbreak. It is critical to investigate how social media triggers residents' preventive behaviour decisions during the COVID-19 outbreak. Methods: This paper selected online shopping as a specific preventive behaviour for empirical investigation. An online cross-sectional survey was conducted through the Sojump website from 1 to 15 March 2020, and a total of 1,289 valid questionnaires were collected from China. This paper uses multiple regression analysis to investigate the heterogeneous impacts of different information sources on residents' online shopping willingness and online shopping behaviour and the heterogeneous impacts of different information content in social media on the transformation of residents' online shopping willingness and online shopping behaviour. Results: The findings indicate that both official-media and self-media positively promote residents' online shopping willingness and behaviour, with official-media having a stronger promotional effect than self-media. Furthermore, official-media and self-media can collaboratively promote residents' online shopping willingness and online shopping behaviour. The ease-of-use and usefulness of information significantly promoted the transformation of residents' online shopping willingness. Conclusions: This study analyses the heterogeneous impacts of social media on residents' preventive behaviours from the perspectives of information source differentiation and information content differentiation, which enriches related studies and provides feasible paths for promoting residents' preventive behaviours.

Since 2019n-CoV has swept the whole world, people's daily life is affected seriously and the public space system is facing to major challenges. Community public space should be re-evaluated and optimized as people change the way they use it. This research conducted a nationwide questionnaire survey in China, which collected the opinions of residents on community public space from the perspective of epidemic prevention and social needs to select research indicators. The questionnaire data were processed through the frequency analysis method, precedence chart and TOPSIS. We found: (1) under the background of the epidemic, people pay more attention to the satisfaction of leisure activities in community public space and the control of social spacing during activities; (2) the current assessment result of community public space risk of 2019-nCoV exposure is 0.386, which is relatively high; and (3) the exposure risk of the community can be effectively reduced by controlling for the two indicators of social distance and social facility sterilization. When the social distance is 1.8–3 m and the facility sterilization is once a day, the community public space minimizes exposure risk. In view of the above results, this paper selects the Wuhan start-up area of Wuhan, China, as an example for carrying out the optimization design of community public space based on the epidemic and the design the space optimization model for the two indicators of social distance and facility disinfection from both software and hardware aspects.

This paper examines the Chinese government's response to four epidemic crises, including COVID-19, and analyzes the similarities and differences in these responses. It argues that while the Chinese government learned from previous epidemics and improved its handling of subsequent outbreaks, a significant variation occurred during the COVID-19 pandemic, which had a detrimental impact globally. Existing scholarly research on China's epidemic responses has often been limited in scope, focusing on individual crises and neglecting the central-local government relationship in crisis decision-making. By adopting a comprehensive approach, this paper delves into the nuanced dynamics of China's responses to these epidemics. It highlights the variations in responses, attributing them to the Chinese government's fear of undermined legitimacy and its consideration of its international image. The government's recognition of the importance of public perception and trust, both domestically and globally, has shaped its crisis management strategies. Through a detailed analysis of these factors, this paper contributes to a deeper understanding of the variations observed in China's epidemic responses. It emphasizes the significance of the central-local government relationship and the government's international image in determining its actions during epidemics. Recognizing these factors can provide policymakers and researchers with insights to shape future epidemic response strategies and foster effective global health governance. [ABSTRACT FROM AUTHOR]

Background: Against the grim background of declining intention to have children, the ravages of COVID-19 have pushed China and the world into a more complex social environment. To adapt to the new situation, the Chinese government implemented the three-child policy in 2021. Objective: COVID-19 pandemic indirectly affects the country's internal economic development, employment, fertility plans or intention, and other major issues related to the people's livelihood, while undermining the stable operation of society. This paper explores the question that will COVID-19 pandemic affect Chinese people's intention to have a third child. And What are the relevant factors inside? Method: The data in this paper are from the Survey released by the Population Policy and Development Research Center of Chongqing Technology and Business University (PDPR-CTBU), including 10,323 samples from mainland China. This paper uses the logit regression model and KHB mediated effect model (a binary response model given by Karlson, Holm, and Breen) to investigate the impact of the COVID-19 pandemic and other factors on Chinese residents' intention to have a third child. Results: The results suggest that the COVID-19 pandemic has a negative effect on Chinese residents' intention to have a third child. In-depth research on the mediating effect of KHB shows that COVID-19 pandemic will further inhibit residents' intention to have a third child by affecting their childcare arrangements, increasing their childcare costs, and increasing their exposure to occupational hazards. Contribution: This paper is more pioneering in focusing on the impact of the COVID-19 epidemic on the intention to have three children in China. The study provides empirical evidence for understanding the impact of COVID-19 epidemic on fertility intentions, albeit in the context of policy support. [ABSTRACT FROM AUTHOR]

From the perspective of migrant times/temporalities, this paper focuses on the temporal experiences among Chinese international students (CIS) who planned to enrol overseas in 2020 but instead chose to stay in China due to the COVID‐19. Specifically, it adopts 'sticky and suspended times' and 'asynchronous and precarious times' to investigate how they encounter a set of temporal disruptions at both everyday and life course levels while staying put in China. Particularly, the paper asks how CIS exercises agency to navigate through temporal dissonances and enhance their immobile state and capital accumulation. Critically, the paper develops a temporally sensitive framework to unpack the multiple kinds of temporalities CIS confront during the pandemic, further advancing studies on 'international student mobility' and 'time in migration'. Additionally, existing studies have largely focused on how time shapes people's mobility and this paper provides an empirical case on the potential of the temporal approach to understanding immobilities.

The papers in this special section focus on modeling and simulation in disaster and emergency management. The COVID-19 pandemic of 2020 has wrought damage globally to a degree that is totally unprecedented in human history.Within three months that the first known death from the illness caused by the so-called novel Coronavirus was reported by state media in China on the 11th of January 2020, close to 1.8 million people worldwide had tested positive, with more than 100,000 deaths reported. By the time the pandemic will have been declared to be under control, millions more are expected to have been infected and tens (possibly hundreds) of thousands more will have perished as a result of the disease. Not only are the numbers of COVID-19 infected people and deaths staggering. Economies throughout the world have suffered tremendously, with many companies forced to shut down, or at the very least significantly scale down, their production of goods and services as a result of the need for social distancing and self-isolation required to prevent the unmitigated transmission of the disease. All this has led to hundreds of millions worldwide losing their employment or other sources of livelihood. Governments of all nations, large and small, developed and underdeveloped, have needed to pump into their economy and onto their struggling citizens whatever financial resources they could manage to generate.

The coronavirus first appeared in China in 2019, and the World Health Organization (WHO) named it COVID-19. Then WHO announced this illness as a worldwide pandemic in March 2020. The number of cases, infections, and fatalities varied considerably worldwide. Because the main characteristic of COVID-19 is its rapid spread, doctors and specialists generally use PCR tests to detect the COVID-19 virus. As an alternative to PCR, X-ray images can help diagnose illness using artificial intelligence (AI). In medicine, AI is commonly employed. Convolutional neural networks (CNN) and deep learning models make it simple to extract information from images. Several options exist when creating a deep CNN. The possibilities include network depth, layer count, layer type, and parameters. In this paper, a novel Xception-based neural network is discovered using the genetic algorithm (GA). GA finds better alternative networks and parameters during iterations. The best network discovered with GA is tested on a COVID-19 X-ray image dataset. The results are compared with other networks and the results of papers in the literature. The novel network of this paper gives more successful results. The accuracy results are 0.996, 0.989, and 0.924 for two-class, three-class, and four-class datasets, respectively. [ABSTRACT FROM AUTHOR]

Team science refers to research initiatives considered in collaboration with scientists from different disciplines or fields. This paper presents a bibliometric analysis for visualization of global research activity concerning the combination of cancer and the COVID-19 pandemic using a team science approach. A bibliometric study was implemented using Web of Science from 2019 to 2021. We analyzed citations to identify description and citations analysis of results, most prolific countries, international research collaboration, most prolific institutions, research areas, most cited papers, and most productive journals. The preliminary data of 2,313 studies that adopted a team science approach were recorded and analyzed. Team science is becoming progressively popular in cancer research. The United States was the most active country, followed by Italy and China. The United States, the United Kingdom, and Italy had the highest level of cooperation with other countries. The most prolific institution was Harvard University, followed by University of London and the University of Texas System. Head and Neck Journal for the Sciences and Specialties of the Head and Neck, Frontiers in Oncology, and eCancerMedicalScience were the most productive journals. Governments, organizations, policymakers, and researchers should pay attention to team science approach at times of disasters such as cancer and COVID-19 to achieve the best strategies for controlling cancer that is currently a world problem.

This article explores the impact of COVID-19 policies on the mobility of elderly individuals in Australia and China. It highlights the digital exclusion faced by older people as smartphone use became mandatory for accessing public spaces and services. The article discusses how this digital exclusion deepened social isolation and exacerbated feelings of loneliness among older individuals. It also examines the gender inequalities and the increased burden on women as unpaid caregivers during the pandemic. The paper emphasizes the need for age-inclusive policies that address intersecting factors and promote equitable access to technology and public spaces. [Extracted from the article]

Purpose: During the coronavirus disease 2019 (COVID-19) pandemic, ubiquitous social media has become a primary channel for information dissemination, social interactions and recreational activities. However, it remains unclear how social media usage influences nonpharmaceutical preventive behavior of individuals in response to the pandemic. This paper aims to explore the impacts of social media on COVID-19 preventive behaviors based on the theoretical lens of empowerment. Design/methodology/approach: In this paper, survey data has been collected from 739 social media users in China to conduct structural equation modeling (SEM) analysis. Findings: The results indicate that social media empowers individuals in terms of knowledge seeking, knowledge sharing, socializing and entertainment to promote preventive behaviors at the individual level by increasing each person's perception of collective efficacy and social cohesion. Meanwhile, social cohesion negatively impacts the relationship between collective efficacy and individual preventive behavior. Originality/value: This study provides insights regarding the role of social media in crisis response and examines the role of collective beliefs in the influencing mechanism of social media. The results presented herein can be used to guide government agencies seeking to control the COVID-19 pandemic. [ABSTRACT FROM AUTHOR]

This paper merges three textual models to construct a series of indicators, which can yield more refined proxies for financial media coverage, to measure the impacts of COVID-19 on Chinese financial markets. Results show that the basic indicator Granger causes the volatilities of bond and stock markets and contributes more to the stock market after the outbreak of COVID-19. Next, four specific market-related indicators have significant effects on the corresponding financial market after the outbreak. Finally, the policy-related indicator has a significant effect on four financial markets after the outbreak, and it causes greater volatility in the stock market. This paper can help the government to stabilize the financial market by managing financial media attention. [ABSTRACT FROM AUTHOR]

Using the policy package pilot implemented in Hubei Province, China, in April 2020 as a natural experiment, we use the synthetic control (SC) and synthetic difference in differences (SDID) methods to estimate the impact of the Chinese government's support policy on the economic resilience and to analyze the mechanisms by which it impacts. This study finds that the policy package has contributed to the growth of economic resilience in the pilot provinces, with the policy package increasing the average economic resilience of the pilot provinces by 0.062 compared to their potential resilience. The validity and robustness of the above conclusions are objectively confirmed by multidimensional quantitative outcomes such as placebo tests, ranking tests, and replacements in calculating resilience. The mechanism analysis shows that the investment in real estate development, the stimulus for consumption, and the core industry development are virtual channels for the policy package to promote economic resilience growth in the pilot provinces. Moreover, traditional investment in transportation fixed assets plays a minor role. This paper quantitatively corroborates the academic idea that government governance capacity affects regional economic resilience (RER), and research can provide empirical support for regional economic recovery and policy support under a major crisis.

Modern diplomacy in the 21st century has become increasingly complex, requiring a broader scope or the performance of more tasks that extend beyond the traditional high politics of old. This means that current diplomats must deal with more diverse global concerns due to the nature of the post-Cold War era marked by diplomatic inflation, the decline of US hegemony, the rise of China, nuclear proliferation, climate change, globalisation, the Fourth Industrial Revolution (4IR), and the COVID-19 pandemic. Due to this diversification of the diplomatic agendas and the inclusion of a growing number of stakeholders, the diplomatic field is experiencing an amplified array of challenges. Therefore, this article examines these major changes and their impact on modern diplomacy by utilising the theoretical framework of the English School where the emphasis is on a 'society of states' and a world united by common humanity. The research also employs a comprehensive qualitative analysis of the mentioned post-Cold War issues and how diplomacy can contribute to mitigating them. The paper then concludes by recommending the need for a more specialised diplomatic corps who are well-versed in technological advancements and digital platforms. By becoming more specialised, diplomacy can become more effective and thus, remain a vital tool in navigating the intricacies of contemporary international politics while mitigating the major challenges the globe faces.

Purpose: This paper examines the impact of the COVID-19 pandemic on low-carbon consumption of dairy products through informational interventions. The empirical findings seek to enlighten developing countries' efforts in coping with climate change and potential dietary transitions. Design/methodology/approach: A randomized controlled trial was designed to examine the effects of purpose-differentiated information interventions on individual dairy consumption. The experiment recruited and randomly assigned 1,002 college students into four groups to receive (or not) environmental or/and health information interventions. Findings: The empirical analysis finds that health and combined information interventions have a positive impact on dairy consumption, while environmental information interventions' effect on dairy consumption is insignificant. In the context of the pandemic, health information interventions positively affected participants' perceptions and preferences for dairy products by delivering knowledge about their role in boosting immunity. However, environmental information interventions failed to do the same things as their insignificant effects on both perception and preference. Originality/value: Macro-external shocks, such as public health events, may offset the impact of universal information interventions promoting pro-environmental behaviors. For a smooth dietary transition to achieve long-term environmental sustainability, diverse stakeholders must be included in more individualized interventions to guide daily consumption, especially in developing countries with large populations.

In early 2020, the spread of COVID-19 resulted in the wide use of online classes in China. Drawing on Foucault’s disciplinary power and De Certeau’s strategy-tactic dialectic, this paper explores the online learning practice of students in a rural junior middle school at Yu Town in Central China during the pandemic, through interviewing the students, teachers, and parents. The findings show that the teachers and the students engaged in a power game in online education and employed a series of strategies and tactics to realize the control and resistance through the creative use of media technologies. The study reveals the paradox that the rural students’ agency and resistance, enabled by the media technologies, may result in negative consequences for their learning and further broaden the gap between rural and urban students, thus reproducing the system that they are dissatisfied with.

Using the theory of transitivity system within Systemic Functional Linguistics as the theoretical basis and the white paper named Fighting COVID-19: China in Action, which was published by the Chinese government on June 7, 2020 as the corpus, with the help of corpus analysis tool, UAM Corus Tool 3, this paper uses a combination of qualitative and quantitative methods to explore the construction of China's national image. The results show that the frequency of material processes is extremely high, which is 88.26%, while existential processes and behavioral processes occupy only an extremely small proportion, 0.73% and 0.09% respectively. Relational processes are in the second rank, 5.34%. The frequencies of verbal processes and mental processes are similar, accounting for 2.97% and 2.6% respectively. Through a detailed analysis of the six transitivity processes, a national image that advocates "people supremacy", selfless collectivism, with strong executive ability and mobilization, and a great responsibility in the international society is found to be constructed. This paper lays a foundation for further studying China's national image in the path of SFL. It also sheds some light on the construction of China's image in the official government document.

The transmission rate is an important indicator for characterizing a virus and estimating the risk of its outbreak in a certain area, but it is hard to measure. COVID-19, for instance, has greatly affected the world for more than 3 years since early 2020, but scholars have not yet found an effective method to obtain its timely transmission rate due to the fact that the value of COVID-19 transmission rate is not constant but dynamic, always changing over time and places. Therefore, in order to estimate the timely dynamic transmission rate of COVID-19, we performed the following: first, we utilized a rolling time series to construct a time-varying transmission rate model and, based on the model, managed to obtain the dynamic value of COVID-19 transmission rate in mainland China; second, to verify the result, we used the obtained COVID-19 transmission rate as the explanatory variable to conduct empirical research on the impact of the COVID-19 pandemic on China's stock markets. Eventually, the result revealed that the COVID-19 transmission rate had a significant negative impact on China's stock markets, which, to some extent, confirms the validity of the used measurement method in this paper. Notably, the model constructed in this paper, combined with local conditions, can not only be used to estimate the COVID-19 transmission rate in mainland China but also in other affected countries or regions and would be applicable to calculate the transmission rate of other pathogens, not limited to COVID-19, which coincidently fills the gaps in the research. Furthermore, the research based on this model might play a part in regulating anti-pandemic governmental policies and could also help investors and stakeholders to make decisions in a pandemic setting.

The Covid-19 pandemic has exerted significant downward pressure on economic activity. In this paper, we examine the extent of the epidemic shock and recovery effects on economic growth by province in China since 2020. We find that the extent of the epidemic shock on economic growth in China has been gradually weakening. Still, the economy has not yet fully recovered from the shock. Also, there is some heterogeneity across provinces in the extent to the economic growth shocked by epidemic and the recovery effects. [ABSTRACT FROM AUTHOR]

African trading brokers in China buy knock‐off or copy goods and move them through customs via bribery to African ports; this trade, although illegal, brings desired global products to Africa. This paper, based on interviews with African trading brokers, examines how the internet and Covid‐19 have affected their trade. African customers can now find out the accurate prices of goods; computerized customs regimes make bribery difficult; and Covid‐19 has raised shipping costs. While the informal economic arrangements of these trading brokers will probably continue despite policymakers' efforts to eradicate them, China may no longer be the source of their goods.

At present, COVID-19 is attracting people's attention worldwide. The rapid spread of the epidemic has had a very large impact on the education sector. Many countries have organized students to engage in online learning and study at home. As a country was seriously affected in the early stage of the epidemic, after a period of hard work, China has developed nationwide online education. Compared with that in many developed countries, the emergence of information technology in China did not occur early. However, the sudden outbreak of COVID-19 forced Chinese schools to carry out large-scale online teaching. Based on the theoretical framework of the interaction between online education policy and public response, this paper combs the change trend of online education policy focus in China in recent 20 years and the change of public response direction in microblog hot search comments after the online education policy was introduced during the epidemic period through a variety of text statistical analysis methods, and discusses the interaction between social public response and online education policy. This paper explains the reasons for China's successful implementation of nationwide online education in primary and secondary schools in early 2020. [ABSTRACT FROM AUTHOR]

Transnational political communication today is being reconfigured by digital technologies and global power transition. Authoritarian state actors such as China are increasingly active on global social media platforms such as Twitter to directly advance their preferred frames with foreign publics in Western democracies, most notably in what could be called Chinese Twiplomacy contesting narrative globally over contentious issues. This paper problematises such Twiplomacy from authoritarians to Western democracies as 'networked transnational frame contestation', arguing that the political and cultural distance between the sending and target countries, the networked affordance of social media, and the national prism of the target countries, all contribute importantly to the complexity of such frame contestation. Through a case study on China's Twiplomacy in contesting coronavirus narrative in the UK, this paper further provides empirical evidence on how 'networked transnational frame contestation' works between politically and culturally distant countries. Using a mixed-method approach combining social network analysis and discourse analysis, this study finds that China's emotion-evoking discursive strategy draws traction but the authoritarian nature of the highly centralised networkedness and that of its discursive strategy, together with the strong cultural discordance with British publics, lead to networked recontextualisation of its intended frames in Britain. British publics, heavily relying on British political elites and press for foreign affairs, invoke shared cultural reference to recontextualise Chinese frames into culturally resonant counterframes. This study proposes a paradigm of 'networkedness within cascades' to understand frame contestation between politically and culturally distant countries. [ABSTRACT FROM AUTHOR]

The 2019 novel coronavirus disease (COVID-19; previously known as 2019-nCoV) outbreak that originated from Wuhan, Hubei province, China, at the end of 2019 was declared a public health emergency of international concern on Jan 30, 2020, by WHO.[1] As a newly appearing infectious disease, COVID-19 garnered great research interest. 2 E Stoye, China coronavirus: how many papers have been published? 3 CC Du, Ministry of Science and Technology: efforts should not be focused on publishing papers before epidemic prevention and control tasks are completed (in Chinese). http://www.caixin.com/2020-01-30/101509614.html Jan 30, 2020, (in Chinese).

Purpose: This study aims to provide a timely review of the COVID-19-related empirical research published in 19 quartile one (Q1) and quartile two (Q2) tourism and hospitality journals in social science citation index (SSCI). Design/methodology/approach: A total of 407 COVID-19-related empirical papers were collected from the 19 SSCI Q1 and Q2 tourism and hospitality journals via Scopus database. Thematic content analysis was supplemented with Leximancer software to identify the research themes/subthemes, research methods and countries/regions of research. Findings: The study found studies of COVID-19's impact on consumer behaviour predominate in number, followed by studies on response actions and recovery strategies, impact on industry or sectors and impact on workers and employees. Based on the research themes identified, a knowledge mapping framework was produced. Over 70% of the studies used quantitative methods with quantitative survey as the dominant method of data collection. The USA and China were found to be the most studied countries. Research limitations/implications: The study reviewed empirical research papers until January 2022 and covered most of the COVID-19-related empirical works in the field. An overview of the current state of COVID-19-related empirical research was provided with some critical discussions and suggestions for future research topics. Originality/value: The findings give researchers a clear index for the current state of the art of COVID-19 research in hospitality and tourism. The paper provides practical implications for industry practitioners to retrieve relevant knowledge from the recent COVID-19-related literature in tourism and hospitality in coping with practical challenges brought by the COVID-19 pandemic.

The COVID‐19 pandemic has issued significant challenges to food systems and the food security of migrants in cities. In China, there have been no studies to date focusing on the food security of migrants during the pandemic. To fill this gap, an online questionnaire survey of food security in Nanjing City, China, was conducted in March 2020. This paper situates the research findings in the general literature on the general migrant experience during the pandemic under COVID and the specifics of the Chinese policy of hukou. Using multiple linear regression and ordered logistic regression, the paper examines the impact of migration status on food security during the pandemic. The paper finds that during the COVID‐19 outbreak in 2020, households without local Nanjing hukou were more food insecure than those with Nanjing hukou. The differences related more to the absolute quantity of food intake, rather than reduction in food quality or in levels of anxiety over food access. Migrants in China and elsewhere during COVID‐19 experienced three pathways to food insecurity—an income gap, an accessibility gap, and a benefits gap. This conceptual framework is used to structure the discussion and interpretation of survey findings and also has wider potential applicability. [ABSTRACT FROM AUTHOR]
