Aim: The aim of the study was to investigate the correlation between fear of COVID-19 and mental health of nurses and the effects of psychological capital and burnout in this relation., Design: A cross-sectional study., Methods: The online surveys were conducted among mainland Chinese nurses. Participants (n = 445; average age 32.89 ± 6.76 years) completed an online-questionnaire based on the Fear of COVID-19 Scale, the Psychological Capital Scale, Maslach Burnout Inventory Human Services Survey for Medical Professionals Scale and the 12-Item Short Form Health Survey. Data analysis was conducted by Pearson's correlation analysis, Harman single-factor test and the bootstrap method for mediating effect testing., Results: (1) The study demonstrated a significant direct effect of fear of COVID-19 on nurses' mental health, as well as on mediating factors such as burnout and psychological capital. (2) Regression analyses confirmed that while psychological capital bolstered mental health, burnout undermined it, with fear of COVID-19 further imposing a negative influence. (3) Fear of COVID-19 exerted an effect on the mental health of nurses by the independent and chain intermediary functions of psychological capital and burnout, resulting in a total mediating effect of -0.233., (© 2024 The Authors.

Aim: Being front-line healthcare professionals is associated with possible severe information anxiety during the COVID-19 pandemic. Investigating signs of information anxiety is the first and key step of its targeted medical intervention. This study aims to explore the signs of front-line healthcare professionals' information anxiety during the COVID-19 pandemic., Design: This study is qualitative research. Grounded theory was used to classify information anxiety signs of front-line healthcare professionals., Methods: Twenty-four front-line healthcare professionals from a general hospital with over 5000 beds in Wuhan were recruited to participate in semi-structured interviews. According to the frequency and frequency variation of signs appearing in interviews, the trends of signs during the virus encounter, lockdown, flattening and second wave were compared. Based on the interviews, those signs that were conceptually related to each other were extracted to construct a conceptual model., Results: Psychological signs (emotion, worry, doubt, caution, hope), physical signs (insomnia, inattention, memory loss, appetite decreased) and behavioural signs (panic buying of goods, be at a loss, pay attention to relevant information, change habits) could be generalized from 13 subcategories of information anxiety signs. Psychological signs were the most in every period of the pandemic. Furthermore, psychological signs decreased significantly during lockdown, while behavioural and physical signs increased. Finally, severe psychological and behavioural signs were associated with physical signs., (© 2024 The Author(s). Nursing Open published by John Wiley & Sons Ltd.)

Purpose: In the domain of shadow education (private supplementary tutoring), Denmark and China may be placed at opposite ends of a spectrum. Denmark has a recently emerged, small, and high-cost sector that mostly serves low achievers, while China has a more industrialized sector with a long history and economies of scale. The paper juxtaposes the two to shed light on each. Design/Approach/Methods: The article is a personal narrative of the author's research experiences. She grew up and had initial education in China before moving to the Nordic realm for 2 years. This provided a set of initial lenses, which were subsequently deployed in research partnership from her current base in China with colleagues in Denmark. Findings: The juxtaposition raises questions that might otherwise not have been asked and provides insights that might otherwise not have been gained. Danish families hesitate to use shadow education for advantages in the egalitarian society, in contrast to Chinese patterns that stress competition and achievement. These facets have implications for the modes of shadow education and even the names of tutorial companies. Originality/Value: The paper has a methodological value in addition to its substantive insights on the trajectories of shadow education in the two countries.

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.

This paper investigates how the COVID-19 pandemic influenced student perceptions of online learning. This study examines how did the COVID-19 pandemic and the first-time transition to online mode of instruction influence Sino-Foreign University student perceptions of online learning in terms of (1) academic dishonesty, (2) privacy and confidentiality, (3) impact of social media on online learning (4) hybrid method and (5) institutional training. In order to judge students' perception of the transition to online learning, this study employed a cross-sectional survey-based design to gauge student perceptions of online learning before, during, and after the transition to remote instruction. This study finds that Sino-foreign University students are more conscious of academic integrity. Social media has a vital role in providing teaching resources, communicating with professors and classmates, and expediting collaboration during the pandemic. A blended learning model might be the best option for a post-COVID-19 environment for higher institutions.

Background: Currently, the knowledge of associations among newly recovered cases (NR), newly healed cases (NH), newly confirmed cases (NC), and newly dead cases (ND) can help to monitor, evaluate, predict, control, and curb the spreading of coronavirus disease 2019 (COVID-19). This study aimed to explore the panel associations of ND, NH, and NR with NC., Methods: Data from China Data Lab in Harvard Dataverse with China (January 15, 2020 to January 14, 2021), the United States of America (the USA, January 21, 2020 to April 5, 2021), and the World (January 22, 2020 to March 20, 2021) had been analyzed. The main variables included in the present analysis were ND, NH, NR, and NC. Pooled regression, stacked within-transformed linear regression, quantile regression for panel data, random-effects negative binomial regression, and random-effects Poisson regression were conducted to reflect the associations of ND, NH, and NR with NC. Event study analyses were performed to explore how the key events influenced NC., Results: Descriptive analyses showed that mean value of ND/NC ratio regarding China was more than those regarding the USA and the World. The results from tentative analysis reported the significant relationships among ND, NH, NR, and NC regarding China, the USA, and the World. Panel regressions confirmed associations of ND, NH, and NR with NC regarding China, the USA, and the World. Panel event study showed that key events influenced NC regarding USA and the World more greatly than that regarding China., Conclusion: The findings in this study confirmed the panel associations of ND, NH, and NR with NC in the three datasets. The efficiencies of various control strategies of COVID-19 pandemic across the globe were compared by the regression outcomes. Future direction of research work could explore the influencing mechanisms of the panel associations., (© 2021. The Author(s).)

Based on Jef Verschueren's Adaptation Theory, Lakoff's definition and Prince et al.'s classification of hedges, this paper takes New York Times and China Daily from January 23rd to April 8th, 2020 as corpus sources, randomly selects 39 COVID-19 reports, and makes a contrastive study of hedges among them, aiming at exploring the similarities and differences in the use of hedges in COVID-19 reports selected from Chinese and American mainstream newspapers and further revealing their influencing factors.

Due to the impact of COVID-19, collaborative online international learning (COIL) increasingly plays an important role in the internationalization of higher education. Based on a participatory case study of a COIL program given at Shanghai University (SHU), this paper explores how students, foreign professors, and professors in China prepare, understand, and experience online teaching, learning, and assessment in a COIL program. Three findings include 1). Organizing COIL Programs with a Global Perspective; 2). Enhancing Teaching and Learning through Intercultural Communication; and 3). The Barriers of COIL in Chinese Universities. Taking insiders' perspectives, we argue that a cultural gap regarding teaching and learning styles can affect COIL programs in Chinese universities, posing challenges for both students and teachers. We suggest that program organizers should focus on the cultural gaps affecting these programs, and provide additional opportunities for intercultural communication to address the cultural gaps.

In educational reform, people actively promote educational innovation by applying intelligent technology. As the main participants in education, people experience a series of psychological and cognitive changes in the teaching process. This autonomy and uncertainty will directly affect the effect of network teaching. Due to the variability in the characteristics of individuals, following the psychological perception and subjective value of people and optimizing the development of wisdom education with a reasonable technical cognitive attitude have become a focus. This study uses the grounded theory method to conduct in-depth interviews and questionnaire surveys on 330 e-learners and extracts 400 codes, 38 concepts, 9 categories and 4 core categories. This paper reconstructs the theoretical model of psychological distance in the network education process and identifies four new dimensions: cost distance, initiative distance, control distance and interaction distance. In addition, the four dimensions reflect four core value needs of learners for online education: convenience, self-efficacy, self-identity and binding force. The paper provides a good theoretical basis to improve the user experience and satisfaction in online education and optimize the level of intelligent education.

The genesis and spread of COVID-19 around the world since 2020 have caused severe impacts in every aspect of people's lives, from work life to recreation, social activities to physical health. Higher education has not been excluded. Universities have altered curriculum, changed delivery methods, provided more counseling, purchased new technology, and altered attendance policy for classroom, athletic, social and artistic events (Hamlin, 2021). To assess the impacts of these changes on college students, the authors created a questionnaire to ask students about their perceptions of these COVID-related impacts on their own personal lives. The survey had 56 questions about how the virus affected their academic, social, financial, physical and emotional lives. Over 800 students responded with objective input and subjective comments. Due to the volume of data, the authors have split the study into two parts. The survey results for the first part, academic and social aspects of the survey, were published in "Understanding the Impact of Covid-19 on College Student Academic and Social Lives," Research in Higher Education Journal Volume 41 (see http://www.aabri.com/manuscripts/213347.pdf). It will sometimes be referred to herein to provide clarity to the reader. The actual survey itself can also be found at that site. This paper focuses on the impact of the coronavirus on student financial and physical well-being, which have become major stressors to this age group and have contributed to higher levels of anxiety and depression. It also examines how the virus has affected their social and emotional well-being. Lastly, recommendations are made to help educators understand the severity of the problem, and to take action to provide assistance for those students who have been adversely affected.

This paper reports on an emerging type of international school, which we refer to as the Chinese internationalized school. This school caters to Chinese citizens and aspires to offer a fusion of national and international curricula. The majority of internationalized schools in China are to be found in large metropolitan centers. Accordingly, the literature has focused on relatively affluent urban centers, such as Shanghai, Suzhou, and Beijing. However, in recent years, internationalized schools have started to emerge outside of metropolitan areas in what have been described as tier-3 and 4 cities, which could also be described as non-urban or rural contexts, due to their remote location and proximity from metropolitan centers. This study adds to the scholarship on internationalized schooling in China by focusing on the struggles that schools in a non-urban contexts are likely to face. Focusing on one school, our interviews with 16 teachers and the school's principal revealed that the school's remote location made recruiting students and teachers problematic. Moreover, the effects of COVID-19 compounded this issue, with many prospective students abandoning their plans to study abroad and instead choosing to study in a local school offering the Chinese national curriculum. As a result, the school was forced to recruit students who did not possess the necessary English language ability to access the content of the Cambridge curriculum. This created a washback effect, which impacted on students' academic achievement, their motivation, and the teaching strategies employed by the teachers. The paper concludes by considering what implications the findings might have for teachers and school leaders in internationalized schools in non-urban contexts.

China detected the first case of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection with Delta variant in May 2021. We assessed control strategies against this variant of concern. We constructed a robust transmission model to assess the effectiveness of interventions against the Delta variant in Guangzhou with initial quarantine/isolation, followed by social distancing. We also assessed the effectiveness of alternative strategies and that against potentially more infectious variants. The effective reproduction number (R t ) fell below 1 when the average daily number of close contacts was reduced to ≤ 7 and quarantine/isolation was implemented on average at the same day of symptom onset in Guangzhou. Simulations showed that the outbreak could still be contained when quarantine is implemented on average 1 day after symptom onset while the average daily number of close contacts was reduced to ≤ 9 per person one week after the outbreak's beginning. Early quarantine and reduction of close contacts were found to be important for containment of the outbreaks. Early implementation of quarantine/isolation along with social distancing measures could effectively suppress spread of the Delta and more infectious variants., (© 2022. The Author(s).)

The unprecedented social disruptions resulting from the COVID-19 pandemic have resulted in rapid change within the family and home. This paper uses semi-structured interviews with parents around the globe to examine the following research questions: 1. How have the spatial and temporal organizations of learning and working in the home been altered throughout the COVID-19 pandemic? 2. What are the alterations in the educational processes and the role of the family in response to the changes caused by the COVID-19 pandemic? We found that typical boundaries, those between the roles of family members, between work or school and home, and between leisure time and work time have been fundamentally blurred. While some of these boundaries are more porous than others, families report fundamental shifts, temporary and permanent in the way they organize their home and family, spatially and temporally, and the roles they take on within the family.

Background: Reflective teaching has long been regarded as playing an important, and potentially empowering, role in teachers' professional learning. The study reported in this paper considered the longer-term significance of teachers' self-reflective learning in the course of their daily emergency remote teaching during COVID19, and how this supported teacher agency. Purpose: This small-scale case study sought to explore, in depth, teachers' perceptions of how their professional learning was realised through reflective practice during emergency remote teaching. Method: Three teachers from primary, junior high, and high schools in mainland China participated in the case study during the spring and fall semesters in 2020. They considered the accommodations they made for emergency remote teaching and the corresponding implications for their professional learning and sense of agency. Data were collected via four-monthly, semi-structured interviews, resulting in a total of five interviews per teacher. These charted the progress of their emergency remote courses in the spring, and allowed for final reflections via a follow-up interview in the fall. Data were analysed thematically. Findings: The resultant four themes and eight categories related to aspects including pedagogical strategies, home-school communication, classroom management, and teachers' technological literacy. Within these, approaches to blending online and offline coursework, valuing sociocultural concerns in classroom interaction, and developing adaptive mindsets were among areas identified as relevant to teachers' professional learning beyond the emergency remote teaching situation. Conclusions: The findings highlight the multiple ways in which professional learning took place through reflective teaching in the remote teaching environment. They draw attention to the importance of situating some professional learning in everyday practice. Understandings gained during remote teaching have broader implications for educators' professional learning and growth in pretertiary education.

This article outlines the trajectory of China's higher education and its strategy of pioneering a brand-new smart e-learning environment that has functionally molded China into a hybrid educational hub. This paper chronicles the almanac of China's offline campus education, depicting how it technologically evolved into an e-learning home-campus nexus. A sequential mixed-methods design was employed to shed light on students' readiness levels toward China's newly implemented smart e-learning platform for tertiary education. The psychometric analyses of the Smart e-Learning Questionnaire and other parametric statistical tests were performed using the Rasch measurement model. Overall, there is strong evidence to suggest that the in-depth qualitative interviews captured more nuanced accounts of the participants' perceived reasons for their moderate level of readiness towards their novel home-campus e-learning course delivery. Evacuated campuses and virtual lessons have become the cliched representation of this pandemic. It is critical that e-learning offerings be contextualised in practical ways to invigorate equitable teaching strategies that can improve e-learning and support the success of China's higher education learning model for the post-pandemic agendum.

Despite the growing body of literature on the structural problems of emergency remote teaching during the COVID-19 pandemic, far too little empirical research has been conducted on university academics' challenges in online pedagogy and what is needed to facilitate their teaching during a time of educational crisis. Thus, this study selects a high-profile Chinese language university as a case study to explore how university academics in China have dealt with the challenges of emergency remote teaching during the pandemic. This paper conducts open-ended interviews with 22 academic faculty members and adopts TPACK concepts to interpret the findings. The results demonstrate how participants find avenues to deal with emergency remote teaching, effective measures universities need to adopt, and ways to facilitate TPACK with academic faculty.

The outbreak of the COVID-19 pandemic has had a significant impact on education. The closure of schools and the cessation of face-to-face classrooms have affected schools and students worldwide. The current need is to transform the traditional classroom to adapt to the new social and educational background. The flipped classroom is usually defined as a strategy to subvert the conventional academic environment; that is, the information transmission part of the traditional face-to-face lecture is removed from the classroom time for online self-learning. The flipped classroom is a highly flexible classroom mode, which has brought significant changes to education. Therefore, this study aims to examine the studies' research trends, advantages, and challenges concerning the flipped classroom for EFL courses during the COVID-19 epidemic. For this purpose, databases including the web of Science (WOS) and Scopus were reviewed, and 15 articles were analyzed. A systematic review was used as the research methodology. The study's findings revealed the effectiveness of flipped classrooms for EFL courses during the pandemic. Based on the review, this paper puts forward suggestions for future research and points out the future development direction.

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]

Background: Since the outbreak of coronavirus disease 2019 (COVID-19), human mobility restriction measures have raised controversies, partly because of the inconsistent findings. An empirical study is promptly needed to reliably assess the causal effects of the mobility restriction. The purpose of this study was to quantify the causal effects of human mobility restriction on the spread of COVID-19., Methods: Our study applied the difference-in-difference (DID) model to assess the declines of population mobility at the city level, and used the log-log regression model to examine the effects of population mobility declines on the disease spread measured by cumulative or new cases of COVID-19 over time after adjusting for confounders., Results: The DID model showed that a continual expansion of the relative declines over time in 2020. After 4 weeks, population mobility declined by -54.81% (interquartile range, -65.50% to -43.56%). The accrued population mobility declines were associated with the significant reduction of cumulative COVID-19 cases throughout 6 weeks (ie, 1% decline of population mobility was associated with 0.72% [95% CI: 0.50%-0.93%] reduction of cumulative cases for 1 week, 1.42% 2 weeks, 1.69% 3 weeks, 1.72% 4 weeks, 1.64% 5 weeks, and 1.52% 6 weeks). The impact on the weekly new cases seemed greater in the first 4 weeks but faded thereafter. The effects on cumulative cases differed by cities of different population sizes, with greater effects seen in larger cities., Conclusions: Persistent population mobility restrictions are well deserved. Implementation of mobility restrictions in major cities with large population sizes may be even more important., (Copyright © 2021 The Chinese Medical Association, produced by Wolters Kluwer, Inc. under the CC-BY-NC-ND license.)

This paper explores existing evidence on indicators of risk to the mental health status of Chinese students studying in Australian universities prior to the COVID-19 pandemic. Studies published from January 1999 to January 2020 were considered. Findings indicated that Chinese students routinely report increased levels of fear, stress, anxiety, depression and social problems, as well as decreased levels of general well-being, while studying in Australia. Numerous factors may exacerbate the issues confronted by Chinese university students studying in Australia, including language barriers; social, academic and financial difficulties; challenges associated with the different education systems of the two countries; and their own underuse of available mental health services. Recommendations for further practice and research are presented based on these findings.

This research paper investigated the adoption behavior of college students toward the e-learning system amidst the current COVID-19. The model was developed and validated based on the Technology Acceptance Model (TAM) and the partial least squares-structural equation modeling (PLS-SEM) was used to analyze the data. The data was generated from 316 Chinese college students based on the convenient sampling technique. The research outcomes indicate that the perceived ease of use is a significant predictor of the intention to use and perceived usefulness of an e-learning system. To our surprise, perceived usefulness does not determine the intention to use an e-learning system. Computer self-efficacy and technical support respectively were significant determinants of the perceived usefulness and the perceived ease of use of an e-learning system. Interestingly, the study showed that internet experience does not influence students' sensitivity to the usefulness and ease of use associated with an e-learning system. The theoretical and managerial implications of these results findings are thoroughly interrogated.

The outbreak of COVID-19 in late 2019 had soon become a pandemic, leading to the lockdown of schools all around the world. To mitigate the negative impacts brought by COVID-19, the educational institutions of all levels have inevitably shifted from face-to-face teaching to online teaching. For English language teaching, fully synchronous online learning has been implemented worldwide, posing a great challenge for both instructors and learners. This study reports on findings of Chinese university English as a foreign language students' perspectives' on synchronous online language learning during the pandemic, with a special focus on their encountered difficulties. Drawing on the qualitative interview method, the study investigated 14 EFL learners at a public comprehensive university in a coastal city in southern China. Using thematic analysis, there are four main difficulties identified in the interviews, namely the lack of learning climate, the cultivation of learner autonomy, changes of interaction patterns, and the adaptation to remote assessment. The paper ends with a discussion of findings and implications for English learning and teaching in the "new normal."

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]

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]

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.

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]

In the process of hikers' choosing a destination, searching for information is one of the important elements, playing a decisive role in decision-making. Based on the Baidu Index for "hiking," this paper analyzes the spatial and temporal characteristics of and factors that influenced network attention to hiking in China from 2016 to 2021. The study found that (1) Network attention to hiking in China was generally relatively stable across the period studied, with highly uneven distribution between different months. The search volume was higher on weekends, and mobile searches increased year by year, far exceeding computer searches. (2) Different regions in China experienced different levels of network attention, with the highest levels in the east, followed by the center, and the lowest in the west. Except for East China, network attention to hiking was highly unevenly distributed within each region. (3) The COVID-19 pandemic increased the geographical concentration index and coefficient of variation but reduced the primacy index. A region's level of economic development, degree of network development, population size, and population age structure are proposed as factors that affect network attention to hiking., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Zhang et al.

Purpose: Previous studies on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have focused on factors that influence the achievement of negative conversion of viral RNA. This study aimed to investigate the effects of the genetic mutations in different SARS-CoV-2 strains on the negative conversion time (NCT) among imported cases in Hangzhou, Zhejiang Province, China, in order to provide valuable insights for developing targeted epidemic prevention guidelines., Methods: This retrospective study involved 146 imported SARS-CoV-2 cases in Hangzhou from 8 April 2021 to 11 June 2022. We compared the SARS-CoV-2-specific indicators, clinical indexes, and NCT among the wild-type (WT), Delta, and Omicron groups. Spearman correlation analysis was used to identify the correlations of NCT with mutation types/frequencies., Results: The mean age of the imported cases was 35.3 (SD: 12.3) years, with 71.92 % males and 28.08 % females. The mean cycle threshold (Ct) values of open reading frame 1ab (ORF1ab) and nucleocapsid (N) RNA were 25.17 (SD: 6.44) and 23.4 (SD: 6.76), respectively. The mutations of SARS-CoV-2 strains were mainly located in N, membrane (M), spike (S), ORF1a, ORF1b, ORF3a, ORF6, and ORF9b genes among the WT, Delta, and Omicron groups. NCT was significantly prolonged in the WT and Delta groups compared to the Omicron group. T lymphocyte, white blood cell, eosinophil, and basophil counts were dramatically higher in the WT group than the Delta group. White blood cell, red blood cell, and basophil counts were significantly lower in the Delta group than the Omicron group. Spearman correlation analysis revealed a significant correlation between the NCT of viral RNA and mutation types of viral genes of WT and Omicron strains. Additionally, NCT was markedly negatively correlated with the frequencies of five mutations in Omicron strains (ORF1b:P1223L, ORF1b:R1315C, ORF1b:T2163I, ORF3a:T223I, and ORF6:D61L)., Conclusions: This study indicates that five mutations in Omicron strains (ORF1b:P1223L/R1315C/T2163I, ORF3a:T223I and ORF6:D61L) shortened NCT in imported SARS-CoV-2 cases., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

After the resumption of work and production following the COVID-19 pandemic, many cities entered a "transition phase", characterized by the gradual recovery of emission levels from various sources. Although the overall PM 2.5 emission trends have recovered, the specific changes in different sources of PM 2.5 remain unclear. Here, we investigated the changes in source contributions and the evolution pattern of pollution episodes (PE) in Wuhan during the "transition period" and compared them with the same period during the COVID-19 lockdown. We found that vehicle emissions, industrial processes, and road dust exhibited significant recoveries during the transition period, increasing by 5.4%, 4.8%, and 3.9%, respectively, during the PE. As primary emissions increased, secondary formation slightly declined, but it still played a predominant role (accounting for 39.1∼ 43.0% of secondary nitrate). The reduction in industrial activities was partially offset by residential burning. The evolution characteristics of PE exhibited significant differences between the two periods, with PM 2.5 concentration persisting at a high level during the transition period. The differences in the evolution patterns of the two periods were also reflected in their change rates at each stage, which mostly depend on the pre-PE concentration level. The transition period shows a significantly higher value (8.4 μg m -3 h -1 ) compared with the lockdown period, almost double the amount. In addition to local emissions, regional transport should be a key consideration in pollution mitigation strategies, especially in areas adjacent to Wuhan. Our study quantifies the variations in sources between the two periods, providing valuable insights for optimizing environmental planning to achieve established goals., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

The devastating effects of COVID-19 pandemic have widely affected human lives and economy across the globe. There were significant changes in the global environmental conditions in response to the lockdown (LD) restrictions made due to COVID-19. The direct impact of LD on environment is analysed widely across the latitudes, but its secondary effect remains largely unexplored. Therefore, we examine the changes in particulate matter (PM₂.₅) during LD, and its impact on the global croplands. Our analysis finds that there is a substantial decline in the global PM₂.₅ concentrations during LD (2020) compared to pre-lockdown (PreLD: 2017-2019) in India (10-20%), East China (EC, 10%), Western Europe (WE, 10%) and Nigeria (10%), which are also the cropland dominated regions. Partial correlation analysis reveals that the decline in PM₂.₅ positively affects the cropland greening when the influence of temperature, precipitation and soil moisture are limited. Croplands in India, EC, Nigeria and WE became more greener as a result of the improvement in air quality by the reduction in particulates such as PM₂.₅ during LD, with an increase in the Enhanced Vegetation Index (EVI) of about 0.05-0.1, 0.05, 0.05 and 0.05-0.1, respectively. As a result of cropland greening, increase in the total above ground biomass production (TAGP) and crop yield (TWSO) is also found in EC, India and Europe. In addition, the improvement in PM₂.₅ pollution and associated changes in meteorology also influenced the cropland phenology, where the crop development stage has prolonged in India for wet-rice (1-20%) and maize (1-10%). Therefore, this study sheds light on the response of global croplands to LD-induced improvements in PM₂.₅ pollution. These finding have implications for addressing issues of air pollution, global warming, climate change, environmental conservation and food security to achieve the Sustainable Development Goals (SDGs)., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

As a response to the damage caused by the spread of COVID-19, the Chinese government has implemented severe quarantine measures that have greatly affected the operational patterns of small and medium-sized enterprises (SMEs). This paper explores the critical role of dynamic capabilities (DCs) in helping Chinese SMEs manage crises, adjust their business strategies, and mitigate the uncertainty caused by the epidemic. Although the importance of DCs in promoting organizational resilience is well recognized, academic research on their specific contributions to business model innovation (BMI) and SME performance improvement during crises remains scarce. Our study fills this gap by pioneering the development and empirical testing of a microintegrated mediation model linking DCs, BMI and organizational performance. By surveying 257 Chinese SMEs severely affected by a pandemic, we verify our hypotheses using partial least squares structural equation modeling (PLS-SEM). Our results strongly show a positive relationship between DCs and BMI and SME performance. In addition, we found that BMI plays a partial mediating role in the interrelationship between DCs and SME performance. Our findings clarify the critical role of BMI as a channel through which SMEs' DCs can be transformed into higher performance in the face of sudden crises. Thus, our results not only contribute to the broader discussion of strategic management and organizational theory but also provide theoretical and practical insights into the mechanisms by which SMEs can increase their flexibility and resilience in a crisis. Thus, our results not only contribute to the broader discussion of strategic management and organizational theory but also provide theoretical and practical insights into the mechanisms by which SMEs can increase their flexibility and resilience in a crisis. Importantly, this study suggests policy and market strategies that can support SMEs in leveraging DCs and BMI for sustained performance, thereby contributing valuable insights for policymakers and business leaders aiming to fortify economic stability and growth in the face of global health emergencies., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Huang, Ichikohji.

Background: While health inequality has been the focus of past scholarly discussions, COVID-19's outbreak and spread have provided a new arena for discussing health inequality, particularly in the context of urban-rural disparities in China. This paper explores the impact of COVID-19 on urban-rural health inequality, and the roles played by socioeconomic status and social capital., Methods: A cross-sectional observational collected data on demographics, mental health, socioeconomic status, and social capital. An online survey was administered from August 27 to August 30, 2020, and, 1936 valid samples were received. Mental health was measured using the Brief Symptom Inventory (BSI-18). This study applied the ordinary least squares regression (OLS) model, and data analysis was performed using STATA., Results: There were 1936 participants, with an equal distribution of genders. Multiple regression analysis showed that the mental health levels of rural youth were superior to those of urban youth ( p  = 0.049), especially when the epidemic was not severe ( p  = 0.013). Socioeconomic status had a significant positive promotion effect on mental health ( p  = 0.008), but the interaction effect between socioeconomic status and the urban-rural divide indicated that the promotion effect of socioeconomic status on the mental health of urban youth was greater than that of rural youth ( p  = 0.04). Social capital had a significant positive promotion effect on mental health ( p  = 0.000), and the interaction effect indicated that this promoting effect did not differ between urban and rural areas ( p  > 0.05)., Competing Interests: The author declares that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Xiao.)

Background: The information epidemic emerged along with the COVID-19 pandemic. While controlling the spread of COVID-19, the secondary harm of epidemic rumors to social order cannot be ignored., Objective: The objective of this paper was to understand the characteristics of rumor dissemination before and after the pandemic and the corresponding rumor management and debunking mechanisms. This study aimed to provide a theoretical basis and effective methods for relevant departments to establish a sound mechanism for managing network rumors related to public health emergencies such as COVID-19., Methods: This study collected data sets of epidemic rumors before and after the relaxation of the epidemic prevention and control measures, focusing on large-scale network rumors. Starting from 3 dimensions of rumor content construction, rumor propagation, and rumor-refuting response, the epidemic rumors were subdivided into 7 categories, namely, involved subjects, communication content, emotional expression, communication channels, communication forms, rumor-refuting subjects, and verification sources. Based on this framework, content coding and statistical analysis of epidemic rumors were carried out., Results: The study found that the rumor information was primarily directed at a clear target audience. The main themes of rumor dissemination were related to the public's immediate interests in the COVID-19 field, with significant differences in emotional expression and mostly negative emotions. Rumors mostly spread through social media interactions, community dissemination, and circle dissemination, with text content as the main form, but they lack factual evidence. The preferences of debunking subjects showed differences, and the frequent occurrence of rumors reflected the unsmooth channels of debunking. The χ 2 test of data before and after the pandemic showed that the P value was less than .05, indicating that the difference in rumor content before and after the pandemic had statistical significance., Conclusions: This study's results showed that the themes of rumors during the pandemic are closely related to the immediate interests of the public, and the emotions of the public accelerate the spread of these rumors, which are mostly disseminated through social networks. Therefore, to more effectively prevent and control the spread of rumors during the pandemic and to enhance the capability to respond to public health crises, relevant authorities should strengthen communication with the public, conduct emotional risk assessments, and establish a joint mechanism for debunking rumors., (©Xiaoqi Liu, Qingyuan Hu, Jie Wang, Xusheng Wu, Dehua Hu.

As an emerging business modality and Internet format, live streaming e-commerce has developed rapidly since its emergence in 2016, especially since the outbreak of the COVID-19 epidemic in late 2019, when an increasing number of businesses from other industries attracted participation. However, with the development of the live streaming e-commerce industry, the industry's market environment is becoming increasingly chaotic. Therefore, during this period, government departments continuously formulate and implement relevant industry policies. In order to exploring the cooperation network structure, policy content distribution, and implementation effectiveness characteristics among publishers, this paper constructs a three-dimensional analysis framework of policy from the perspective of policy tools, policy effectiveness evaluation and policy publishers. The results show that in terms of policy tools, the overall structure of policy tools in the live streaming e-commerce industry is unreasonable, and different types of policy tools are significantly diverse. The proportion of environmental policy tools is greater than that of demand-based and supply-based policy tools, accounting for 62.97%, and among them, the tools related to industry regulation and management account for the largest proportion of the total, which greatly suppresses the enthusiasm of various entities in the industry for development. In terms of policy effectiveness evaluation, most of the policies do not formulate detailed long-, medium-, or short-term goals, nor are the policy priorities, incentive measures, or action modes perfect, indicating that the government's pushing and pulling forces for the live streaming e-commerce industry are insufficient. Finally, in the subject dimension of policy release, the synergy of relevant subjects is constantly improving, but there is also a phenomenon of over-concentration in the synergistic departments., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Wang et al.
