During attempts to prevent and control the COVID-19 pandemic in China, higher education programs shifted their traditional educational models to online models. This paper aimed to explore how Chinese universities organized online teaching and learning during the pandemic. It investigated the factors affecting the implementation of online teaching and provided policy recommendations for improving the quality of education in the post-pandemic period. The primary data for this study came from in-depth interviews with nine students and five teaching and administrative staff at eight major universities in mainland China. Literature was obtained in both English and Chinese from January 2020 to September 2021. Peer-reviewed journals, policy reports, and university documents regarding online education in Chinese universities were reviewed, and their challenges and countermeasures were investigated. The paper found that the implementation of online education was affected by various sources, including technologies, teachers' teaching skills, network information literacy, and students' learning motivations and self-directed learning skills. Based on the insiders' views, the paper suggested that to promote the quality of online education in the post-COVID-19 pandemic, higher education institutes and programs could develop their infrastructure construction, improve teachers' quality of teaching, and focus on students' learning motivations.

The 2022 anti–zero Covid White Paper protests that erupted in China and its diaspora demonstrated the intertwinement of politics and performance in contemporary China. The symbolic dimensions of blank sheets of A4 paper and other performative tactics used in these demonstrations exemplify the shifting roles of performance art in the field of contemporary Chinese art.

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.

The enhancement of regional comprehensive development ability is significantly impacted by the study on the implementation effect of regional integration strategies. The integration strategy's impact on urban development during COVID-19 in the Yangtze River Delta(YRD) is unclear. According to prior industrial transfer theory, Hefei, Anhui's capital, is difficult to transfer industries, and other YRD cities push industry integration in Anhui. This study employs the theory of economic and land resource use to examine the resilience of the industrial economy during an epidemic by using industrial land as a representation of industrial economic development. The three cities in Anhui-Wuhu, Maanshan, and Chuzhou (Wu-ma-Chu) were selected as the research area. The study employed the UNet deep learning method to detect the land use types in Wu-ma-Chu. The land transfer matrix and the standard deviation ellipse were utilised to research the alterations in industrial land use and the spatial distribution of industrial output value, respectively. The results showed that the industrial land in Machu continued to grow during the outbreak, highlighting the resilience of the region's industrial economy. During 2019-2022, the elliptical ring of industrial output value is distributed in Nanjing, revealing the radiating role of Nanjing in integrating into the integration of the YRD. This confirms China's YRD integration strategy, strengthens regional economic resilience, and encourages coordinated regional economic development., (© 2024. The Author(s).)

Although previous research has reached agreement on the significant impact of particulate matter (PM 2.5 ) on respiratory infectious diseases, PM 2.5 acts as an aggregation of miscellaneous pollutants and the individual effect of each component has not been examined. Here, we investigate the effects of PM 2.5 components, including black carbon (BC), organic carbon (OC), sulfate ion (SO 4 ), dust, and sea salt (SS), on the morbidity and mortality of the recent respiratory disease, i.e. COVID-19. The daily data of 236 countries and provinces/states (e.g., in the United States and China) worldwide during 2020-2022 are utilized. To derive the pollutant-specific causal effects, optimal instrumental variables for each pollutant are selected from a large set of atmospheric variables. We find that one µg/m 3 increase in OC increases the number of cases and death by about 3% to 6% from the mean worldwide during a lag of one day up to three days. Our findings remain consistent and robust when we change control variables such as the flight index and weather proxies, and also when applying a sine transformation to the positivity and death rate. When analyzing health effects among different areas, we find stronger impact in China, for its higher local OC concentration, as opposed to the impact in the United States. Health benefits from PM 2.5 pollution reduction are comparatively high for developed regions, yet decreases in cases and deaths number are rather overt in less developing regions. Our research provides inspiration and reference for dealing with other respiratory diseases in the post-pandemic era., (© 2024. The Author(s), under exclusive licence to Springer Nature B.V.)

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.)

Building on a theoretical model of decision-making under risk and uncertainty, this paper examines how Chinese college students made decisions about international moblity or immobility during the COVID-19 pandemic. The paper finds that among the 118 interviewees, most continued to choose to study abroad, whilst some gave up after getting offers from prestigious Western universities. We further analysed the divergent patterns of two choices which can be explained by resilience to risks and uncertainties and lack of thereof. For those who have given up studying abroad, the symbolic capital and labor market advantages brought by degrees (especially master degrees) from Western universities have become uncertain and offset by the risk of the epidemic. These findings suggest that, in addition to safety, college students will prefer certainty more than before when choosing whether to go abroad and the study abroad landscape may change based on this mindset.

In an attempt of curricula improvement, many seek to create new approaches that would help develop the necessary knowledge within a shorter period of time. The primary purpose of this paper is to investigate the role of interactive piano teaching in distance learning. The paper suggests new learning approaches to interactive piano instruction. The training programme is based on interactive groups, the Flowkey application, technical and psychological aspects, improvisation, changing role positions, and the development of self-control. The programme results showed that 83% out of 120 students demonstrated a high level of knowledge, and only 2% showed a low level, which was explained by absenteeism. 28% out of 120 students learned to recognise melodies, 27% improved rhythm and tempo, 25% gained two-handed playing skills, and 20% out of 120 students developed improvisation skills. The results have scientific value for researchers engaged in studying various training programmes.

Transnational routes such as direct-entry have become a more attractive option for Chinese students, due to the pandemic-imposed travel restrictions in China. The rise of Chinese direct-entry students can potentially lead to a significant increase in demand for academic and non-academic support not only after their arrival, but also before their departure from China. By applying Schlossberg's transition theory, this paper seeks to develop a good understanding of the academic and social belonging of Chinese direct-entry students in the UK through re-analysing the portraits (written narratives) of a previous research project. The findings indicate that these students were feeling disconnected from the academic and social communities. The factors affecting their sense of belonging are described using the 4S framework, namely self, strategies, situation and support. The paper ends with recommendations to key university stakeholders on how the partner institutions in China and the UK can help enhance a sense of academic and social belongingness of Chinese direct-entry students.

Higher education informatization (HEI) is an interdisciplinary field that examines the use and integration of information and communication technologies (ICTs) in higher education. This paper provides a bibliometric and visual analysis of the research trends, patterns, and topics in this field. Using the Web of Science database, the authors selected and analyzed 199 SCI and SSCI papers on HEI published from 2000 to 2023 by VOSviewer and CiteSpace software. The results indicate that the publication volume of HEI research has grown significantly in recent years. The author network shows the collaboration and contribution of different researchers and institutions, while the journal network reveals the multidisciplinary nature and scope of the field. The keyword network and the burst keyword analysis identify the main research themes and the emerging hot topics in HEI. The co-citation network of sources illustrates the theoretical and methodological foundations and influences of the field. The paper concludes with some implications and suggestions for future HEI research.

This paper addresses the substantial role of clan loyalty in promoting COVID-19 diffusion in China. Using a city-date panel dataset of observations from 183 cities (prefecture-level and above) in the period of the special long holiday of Chinese New Year in 2020 (January 24-March 1), we find that regions with higher clan loyalty have more COVID-19 cases than regions with lower clan loyalty. A one standard deviation increase in clan loyalty is associated with an 8.1% increase in COVID-19 cases. We further document that clan loyalty drives COVID-19 cases by promoting mass gatherings, exploiting a staggered difference-in-differences (DID) regression based on city community-management policy shocks. Our paper provides novel evidence of one negative public health consequence of clan loyalty, namely, its aggravation of COVID-19 cases., (© 2023 John Wiley & Sons Ltd.)

With the recurrence of infectious diseases caused by coronaviruses, which pose a significant threat to human health, there is an unprecedented urgency to devise an effective method to identify and assess who is most at risk of contracting these diseases. China has successfully controlled the spread of COVID-19 through the disclosure of track data belonging to diagnosed patients. This paper proposes a novel textual track-data-based approach for individual infection risk measurement. The proposed approach is divided into three steps. First, track features are extracted from track data to build a general portrait of COVID-19 patients. Then, based on the extracted track features, we construct an infection risk indicator system to calculate the infection risk index (IRI). Finally, individuals are divided into different infection risk categories based on the IRI values. By doing so, the proposed approach can determine the risk of an individual contracting COVID-19, which facilitates the identification of high-risk populations. Thus, the proposed approach can be used for risk prevention and control of COVID-19. In the empirical analysis, we comprehensively collected 9455 pieces of track data from 20 January 2020 to 30 July 2020, covering 32 provinces/provincial municipalities in China. The empirical results show that the Chinese COVID-19 patients have six key features that indicate infection risk: place, region, close-contact person, contact manner, travel mode, and symptom. The IRI values for all 9455 patients vary from 0 to 43.19. Individuals are classified into the following five infection risk categories: low, moderate-low, moderate, moderate-high, and high risk., (© 2022 Society for Risk Analysis.)

This paper explores a possible future of postdigital education in 2050 using the means of social science fiction. The first part of the paper introduces the shift from 20th century primacy of physics to 21st century primacy of biology with an accent to new postdigital--biodigital reconfigurations and challenges in and after the COVID-19 pandemic. The second part of the paper presents a fictional speech at the graduation ceremony of a fictional military academy in a fictional East Asian country in 2050. This fictional world is marked by global warfare and militarization, and addressed graduates are the first generation of artificially evolved graduates in human history. The third part of the paper interprets the fictional narrative, contextualizes it into educational challenges of today, and argues for a dialogical, humanistic conception of new postdigital education in a biotech future.

This paper draws attention to the current and possible effects of COVID-19 on the mobility trajectories of mainland Chinese students studying in Asia. By drawing on 35 biographical interviews, this paper focuses on their decision to study in Asian countries and regions. Particularly, it calls for more attention to Asia in global student mobilities and discusses whether COVID-19 has changed the position of Asia in the global landscape of student mobility. Results show that even if COVID-19 provides an opportunity for Asian universities to embrace more international students, Asia still lacks the capability to attract great numbers of them. Finally, the study argues that college students' choice of mobility destinations is shaped by their perception of the central-periphery structure of higher education, which is hard to be shaken by the pandemic.

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.

The COVID-19 pandemic has popularized online learning as a mode of teaching and learning in universities, thereby exacerbating college students' stress levels in multiple ways. To enhance the quality of college student training, it is crucial to investigate the impact of perceived stress on their online self-directed learning. Using questionnaire data from 969 college students across China, this study performed an empirical analysis of the influence of perceived stress on their online self-directed learning, while also exploring the mediating role of phone dependence and the moderating role of self-management ability. The findings indicate that, firstly, perceived stress has a significant and positive effect on college students' online self-directed learning. Secondly, phone dependence masks the positive impact of perceived stress on students' self-directed learning, thereby weakening the effects of employment and learning stress on their online self-directed learning. Thirdly, self-management ability positively moderates the relationship between employment, social, interpersonal, and learning stress and college students' online self-directed learning. Fourthly, rural college students' online self-directed learning is more susceptible to employment, social, and interpersonal stress; vocational college students' self-directed learning is more influenced by employment, social, and learning stress; and students in the "Double First-Class" initiative universities are more likely to develop phone dependence. Therefore, this paper asserts that using stress reasonably, controlling stress appropriately, channeling stress properly, and enhancing self-management abilities can aid college students in learning autonomous online.

Using a monthly data between 2008 and 2019, this study investigated how the development of the Internet technologies has shaped the consumer consumption pattern of different types of paper products in China during this period. In detail, this study covers four major types of paper products in the Chinese market: newsprint, printing paper, household paper, and packaging paper. The developments of Internet technologies were decomposed into two aspects: the communication technology (CT) and the software platform technology (PT). Granger causality analysis was employed to determine whether the consumption pattern of paper products was affected by the development of the Internet. Furthermore, impulse-response analyses were utilized to measure how the consumption pattern of each paper product was shaped by the development of each aspect of Internet technologies, i.e., CT or PT. The empirical results suggested that the Internet developments are causing the consumption patterns shifts of all four paper products. Specifically, the consumptions of newsprint and printing paper were driven by both CT and PT. However, the consumptions of packaging paper and household paper were driven by the PT only. Compared to the development of CT, we found that the quick evolution of PT plays a more significant role in shifting people's consumption of paper products in China. The empirical results revealed by this study could provide valuable economics and policy implications to both academia and relevant industries. • Internet development has shifted the paper products consumption pattern in China. • Development of internet boosted the demand for printing paper and household paper. • Development of internet suppressed the demand for newsprint. • The effects of internet technological development are separated into two aspects. • Emerging Internet platforms shifted the consumption of paper products efficiently.

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.

China is the foremost global consumer, producer, and exporter of fresh apples. In 2021, China produced roughly 44 million tons of apples and exported just over 1 million tons, a nearly 2% increase over the previous year. However, the ongoing COVID-19 pandemic has had a detrimental impact on global trade and has led to a decrease in China's agricultural exports. The present study aims to contribute to the existing body of literature by analyzing plausible macroeconomic determinants that might impact China's apple exports. We used novel dynamic autoregressive distributed lag (DYARDL) simulations to model causal relationships among fundamental economic parameters. We made use of annual time series data from 1990 to 2020 from the World Bank and China's national statistical bureau. We found that increases in apple orchard area, apple production, and trade openness had a positive impact on apple exports over both the short and long term. Conversely, decreases in the prices of exported apples, agrochemicals, and carbon emissions in the agricultural sector had a positive impact on the long-term and short-term exportation of apples. Finally, we note that pictographic illustrations from the DYARDL simulations provide corroborative evidence for our findings. Based on the study results, this study proposes that the adoption of technological advancements in apple orchards could potentially enhance apple production while simultaneously upholding environmental sustainability., (© 2023.

This study aims to explore the early experiences of frontline nurses at the beginning of the COVID-19 pandemic in China as expressed through social media posts. This study used an explanatory sequential mixed-method design. Text mining was used for sentiment analysis. The chi-square test was used to compare the differences in the composition ratio of sentiment classification of posts in different months. Word frequency was statistically analyzed. Further thematic analysis was also performed. The primary sentiments of the posts were discovered to be positive and neutral. The number of posts containing positive emotions was the lowest in January, peaked in March, and gradually declined in April 2020. The following nurse-oriented narrative themes were developed: "To see and be seen," "Moving forward amid adversity and support," and "Returning to everyday life and constructing meaning." The sentiments of Chinese nurses in response to the pandemic fluctuated, with positive emotions in the early stage, but it could not be sustained. This study recommends nurses could be encouraged to engage in expressive writing while adhering to ethical guidelines., (© 2023 John Wiley & Sons Australia, Ltd.)

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).)

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.

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.

Educational hub refers to centres of excellence in higher education and research whose aims are to provide high-quality education for both national and international students to enhance the competitiveness of the country. These educational hubs provide an opportunity for knowledge exchanges and innovation in local regions through education and training. In response to the COVID-19 pandemic, rapid shifts were made towards online learning in education around the world. Although the lockdown is over, remote learning will likely play an increasingly prominent role in education. The adoption of scaled remote learning during the pandemic provided evidence of the importance of online learning. They offer an insight into global society, helping prepare students for an increasingly interconnected world by facilitating links between different regions. Educational hubs can be tied to distance learning and are successful in attracting international students when offering a combination of distance learning methods and innovative programs. This paper examines the phenomenon of educational hubs in higher education for international education through online learning with digital technology. New opportunities for online and distance learning within the definition of educational hubs are analyzed, and three online and blended learning models that reflect the development of educational hubs based on COVID-19 conditions of education are offered. In addition, the successful cases and experiences of distance learning hubs in China and Iran in recent years are described.

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.

Since the 2010s, Portugal has experienced a considerable growth in the number of Chinese international students, who have been attracted by the country's image of tolerance and openness for diversity. However, as it was reported in other contexts, throughout the health crisis, these students were blatantly confronted with racial microaggressions in their daily routines inside and outside their higher education institutions' facilities. Drawing on evidence from 30 in-depth interviews conducted with Chinese international students in Portugal and following a thematic analysis approach, this paper analyses how they frame and perceive their encounters with racism in their daily lives during the pandemic. We argue that Chinese international students resort on distinct discursive strategies to negotiate their encounters with racism during their sojourns in Portugal throughout the health crisis and to negate their "otherness" as a racial minority in the country.

More recently, the COVID-19 pandemic outbreak has created massive economic policy uncertainty (EPU). EPU and its economic fallout have been a hot topic of study; however, the impact of EPU on CO 2 emissions has been seldom addressed to date. This paper investigates the effects of the EPU on CO 2 emissions. It elucidates the role of EPU in moderating the environmental regulation-CO 2 emissions nexus at the national and regional levels using the panel data model and provincial panel data from 2003 to 2017 in China. The main empirical results are as follows. The EPU has a negative impact on carbon emissions; however, this relationship is non-significant even at the 10% level in the central and western region datasets. Environmental regulation positively increases the CO 2 emissions implying that the green paradox occurs in the whole and western regions datasets. From the perspective of the moderating effect of uncertainty, EPU exerts a positive impact upon the environmental regulation-CO 2 emissions nexus in the whole and western region datasets. The moderating effect is not significant in the eastern and central regions. The results demonstrate that the re-examination of the EKC hypothesis is inconclusive. Kuznets relationship between economic growth and CO 2 emissions for the national, eastern, and central samples was confirmed. In contrast, CO 2 emissions monotonically rise as GDP grows for western datasets. Based on the overall findings, some policy implications were put forward. We recommend that the local government should consider EPU to improve the institutional environment. Further, different regions should implement various environmental policies according to regional conditions maximizing the emission reduction potential., (© 2021.

Although the impact of the global COVID-19 pandemic in terms of school closure and the sudden shift to online learning has started to be explored, little has so far been written about the impact on teachers. This paper addresses this gap by drawing on the first author's autoethnographic experiences of working in the growing body of 'non-traditional' international schooling in Shanghai, China, during the first wave of the pandemic in early 2020. These experiences are complemented by insights from other teachers from the author's school site, leading to a hybrid (auto)ethnographic perspective. By utilising and developing the emergent concept of 'precarious privilege', we can see that whilst the pandemic has restricted teachers' movements and agency in a physical sense through lockdowns and travel restrictions, this immobility also fosters new symbolic and physical spaces, which in turn give rise to new forms of privilege. The privilege in this context is not financial, as is often the case, but rather existential (reclaiming a more authentic self) and spatial (the school offers teachers security) in nature. This fresh, nuanced approach to discussing precarity is timely and necessary. Given the novelty of the situation we now find ourselves in, new positionings are required to orient the individual and the researcher to a post-pandemic world. This paper offers one such positioning in the form of autoethnography for (re)imagining precarity and privilege in international schooling within the context of an emerging new world.

Despite the role of public health interventions in controlling disease transmission and protecting the public during the COVID-19 emergency, the implementation of quarantine restrictions has raised serious ethical concerns, especially in relation to the well-being of vulnerable populations. Drawing on the lived experiences of rural Chinese migrants who are subject to pandemic control, the authors highlight their inadequate capacities to manage the risks associated with the pandemic and adjust to quarantine restrictions. Informed by an ethical discourse of vulnerability, we show that underpinning this group's deficient coping strategies is a range of detrimental social structures and institutions that have developed under the persistent rural-urban divide in China. These structural constraints and pathologies expose rural migrants to serious risks and uncertainties while depriving them of the means and resources necessary to protect their own interests in the process of complying with quarantine restrictions. Understanding the plight of rural Chinese migrants as a structural problem also has implications for the global response to the COVID-19 pandemic. We further suggest a need for state intervention to mitigate structural deficiencies and empower the vulnerable during the COVID-19 era., (© 2023. Journal of Bioethical Inquiry Pty Ltd.)

This paper analyzes the epidemiological and economic effects of quarantines. We use a basic epidemiological model, a SEIR-model, that is calibrated to roughly resemble the COVID-19 pandemic, and we assume that individuals that become infected or are isolated on average lose a share of their productivity. An early quarantine postpones but does not alter the course of the pandemic at a cost that increases in the duration and the extent of the quarantine. For quarantines at later stages of the pandemic there is a trade-off between lowering the peak level of infectious people on the one hand and minimizing fatalities and economic losses on the other hand. A longer quarantine dampens the peak level of infectious people and also reduces the total number of infected persons but increases economic losses. Both the peak level of infectious individuals and the total share of the population that will have been infected are U-shaped in relation to the share of the population in quarantine, while economic costs increase in this share. In particular, a quarantine covering a moderate share of the population leads to a lower peak, fewer deaths and lower economic costs, but it implies that the peak of the pandemic occurs earlier., (© 2021.

The COVID-19 has been a worldwide pandemic and it needs for studies related to effect on people's demand for insurance during the pandemic which is an important way to transfer risk. However, there is a lack of research linking COVID-19 and people's demand for insurance. The objective of this paper is to investigate the impact of COVID-19 pandemic on issuance demand, using data covering 241 cities on confirmed COVID-19 cases and insurance company revenue in China. The empirical results show that more confirmed COVID-19 cases are associated with greater per capita insurance revenue and the results are robust when considering endogeneity concern. Economically, the per capita insurance revenue increases by 0.896 Yuan for each more confirmed case. In terms of insurance type, the greatest increased insurance revenue is for life insurance, followed by health insurance. We further consider the heterogeneity of regions and find that the impact of COVID-19 on insurance revenue only exists in regions with worse medical treatment conditions or higher medical burden., (© 2021.

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.

The Belt and Road Initiative (BRI) was designed to promote economic and trade cooperation between countries along the Belt and Road (B&R), specifically by building an international trade network. Ecological resources are the basis for human survival. Countries along the B&R transform ecological resources into ecological products by production activities. These products can then be used for trade, thereby driving the countries' economic development. This study uses net primary productivity (NPP) as a unified measure of ecological products, and explores the pattern changes of ecological product trade in countries along the B&R, from 2013 to 2019 (from the BRI proposal to the outbreak of COVID-19). The purpose of the study is to reveal the impact of the BRI on the trade of ecological products. The results show that (1) the trade scale of ecological products in the B&R region has changed significantly. The total volume of traded ecological products increased from 2071.74 to 2631.00 TgC. This represented an increase of about 26.99%, or 7.41% higher than the global average. (2) The spatial distribution pattern of ecological product trade did not change significantly in countries along the B&R. However, the gravity centers of the total and net trade volume of ecological products moved 120.74 km to the northeast and 392.98 km to the southeast, respectively. (3) The trade structure of ecological products in the B&R region, six sub-regions, and most countries remained relatively stable. Only the proportion of the livestock products trade in Mongolia and the proportion of the forest products trade in Bhutan have increased significantly. This finding suggests that the strength and breadth of the construction of unimpeded trade in countries along the B&R still need to further strengthened, in order to accelerate the realization of the vision of the Green Silk Road., (© 2023.

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.
