COVID-19 first appeared in December of 2019 in Wuhan, China. Since then, it has become a global pandemic. A robust and scalable diagnostics strategy is crucial for containing and monitoring the pandemic. RT-PCR is a known, reliable method for COVID-19 diagnostics, which can differentiate between SARS-CoV-2 and other viruses. However, PCR is location-dependent, time-consuming, and relatively expensive. Thus, there is a need for a more flexible method, which may be produced in an off-the-shelf format and distributed more widely. Paper-based immunoassays can fulfill this function. Here, we present the first steps toward a paper-based test, which can differentiate between different spike proteins of various coronaviruses, SARS-CoV-1, SARS-CoV-2, and CoV-HKU1, with negligible cross-reactivity for HCoV-OC43 and HCoV-229E in a single assay, which takes less than 30 min. Furthermore, our test can distinguish between fractions of the same spike protein. This is done by an altered assay design with four test line locations where each antigen builds a unique, identifiable binding pattern. The effect of several factors, such as running media, immunoprobe concentration, and antigen interference, is considered. We find that running media has a significant effect on the final binding pattern where human saliva provides results while human serum leads to the lowest signal quality.

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.

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

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.

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.

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.

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.)

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 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.

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.)

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.

Background: Many patients with Covid-19 have underlying cardiovascular disease or develop acute cardiac injury during the course of the illness.

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.

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.)

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.

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.

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 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]

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.

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).)

COVID-19 has transformed higher education learning and teaching practices globally. Tertiary students, internationally face both opportunities and challenges in learning and adapting to this paradigm shift in the delivery of education. It remains unclear how students in international contexts are responding to these changes in digital learning during and post-COVID-19. This paper aims to compare student perceptions of digital competence, confidence, and resilience in present times using data from surveys of tertiary students from Australia, Cambodia, China, India, and Malaysia. There are disparities not only in the teaching and learning pedagogies amongst these countries but also in the levels of technological advancement, infrastructure support, and pace of digital innovation in the delivery of courses. These differences have put in focus students' both digital competencies and resilience as they pursue higher education on various digital learning platforms. Resilience includes the ability to bounce back or adapt from stress (Smith et al., 2008). Digital resilience is students' tech-savviness and preparedness to adapt to different digital environments as they pursue higher education. This paper examines the perceptions of tertiary undergraduate students from these countries in this emerging new digital learning norm. A total of 687 tertiary students from the aforementioned countries participated in a survey to questions related to digital competence, confidence in using and/or adapting to digital innovation, and resilience. Statistically significant attributes are identified to help better understand the challenges these culturally diverse students perceive in digital learning environments. This study will reveal barriers that impact the digital transformation of undergraduate students which can be used to recommend necessary teaching and learning support frameworks to enhance their digital competence and resilience. This will help tertiary institutions better equip all stakeholders in adapting to the new normal of higher education in the future.

The entire education system, from elementary school to higher education, distorted during the lockdown period. The latest 2019 coronavirus disease (COVID-19) is not only recorded in China, but also globally. This research is an account of the online teaching paradigm assumed in the teaching method by most of universities in China and subsequent tests over the course. It looks forward to offering resources rich in knowledge for future academic decision-making in any adversity. The aim of this research paper is to explain the prerequisites for online education and teaching during the COVID-19 pandemic and how to effectively turn formal education into online education through the use of virtual classrooms and other main online instruments in an ever-changing educational setting by leveraging existing educational tools. The paper uses both quantitative and qualitative research approaches to analyses the views of online teachers and students on the learning regime, with specific attention to the online learning regime implementation process. In the midst of the COVID-19 outbreak, the purpose of this article is to provide an in-depth overview of online learning. These activities took place during a time of isolation, including the creation of a link between the process of change management and the online learning process in the education system to tackle current issues of academic interference and, however, the re-establishment of educational practice and debate as a normal system of procedural education.

This rapid systematic review aims to examine emerging evidence on the effects of COVID-19 on educational institutions and assess the prevalence of e-learning changes in the sector. This paper reviews literature on learning, teaching, and assessment approaches adopted since the COVID-19 outbreak, and assesses the impact on the sector, staff, and students, summarizing findings from peer-reviewed articles. It categorizes these into five key themes: (1) digital learning; (2) e-learning challenges; (3) digital transition to emergency virtual assessment (EVA); (4) psychological impact of COVID-19; and (5) creating collaborative cultures. This represents the first systematic review of COVID-19's impact on education, clarifying current themes being investigated. The author suggests that the term 'emergency virtual assessment' (EVA) is now added for future research discussion. Finally, the paper identifies research gaps, including researching the impact on lesser developed countries, the psychological impact of transition, and the important role of leadership and leadership styles during the transition and handling of the pandemic.
