The Signalling Effect of Corporate Social Responsibility Reporting: Evidence From Short Selling

Using exogenous regulatory changes that have gradually removed short‐sale restrictions in China's stock exchanges, we examine how such deregulation influences firms’ corporate social responsibility (CSR) reporting. Our findings indicate a significant improvement in the calibre of CSR reporting among firms designated as qualified for short selling in a deregulation pilot program (pilot firms) compared to non‐pilot firms. Moreover, our empirical evidence shows that the improvement in CSR reporting practices is greater for pilot firms experiencing stronger downward price pressure, negative earning news, higher bankruptcy risk, greater ownership concentration, and those classified as state‐owned enterprises. These results demonstrate that firms susceptible to price declines from short selling utilize CSR reporting as a visible and credible signal to safeguard and enhance corporate reputation, garnering increased stakeholder support.

Assessment of myocardial injury by SPECT myocardial perfusion imaging in patients with COVID-19 infection in a single center after lifting the restrictions in China.

To assess myocardial injury using rest single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) in patients with COVID-19 and to evaluate whether myocardial injury detected by rest MPI predict the prognosis of symptoms after 6months follow-up. Patients suspected of myocarditis between December 2022 and March 2023, after the lifting of COVID-19 pandemic restrictions, and between December 2018 and March 2019, prior to the pandemic, were referred to our study. All patients underwent rest MPI. One hundred and sixty four patients with COVID-19 infection after the lifting of pandemic restrictions and 101 patients before the pandemic were included as the study and control groups, respectively. One hundred and fifty three patients of the study group and 83 of the control group presented symptoms when they initially visit to our department. Compare the parameters of myocardial injury detected by rest SPECT MPI between the two groups and then investigate the association between myocardial injury and symptom prognosis in symptomatic patients of both groups. Total perfusion defect (TPD) (4.2% ± 3.3% vs. 2.3% ± 2.2%, P < 0.001), summed rest score (SRS) (5.3 ± 5.4 vs. 2.7 ± 2.0, P < 0.001), the proportion of patients with TPD > 4% (43.3% vs. 17.8%, P < 0.001), TPD > 10% (6.71% vs 0, P < 0.001), SRS > 4 (40.2% vs 15.8%, P < 0.001), SRS > 10 (12.8% vs 0, P < 0.001), the number of abnormal perfusion segments (3.9 ± 3.1 vs. 2.4 ± 1.7, P < 0.001) were all significantly higher in the study group. All the parameters of rest MPI were not associated with the prognosis of symptoms in symptomatic patients of both groups after 6months follow-up. Myocardial injury in COVID-19 patients could be assessed by rest SPECT MPI. The COVID-19 patients could exhibited a higher frequency and greater severity of myocardial injury than uninfected control patients. Myocardial injury assessed by rest MPI did not predict for the prognosis of symptoms in symptomatic patients of both COVID-19 patients and uninfected patients.

Suicidal ideation and suicide attempts among students aged 12 to 24 after the lifting of COVID-19 restrictions in China: prevalence and associated factors.

To investigate the prevalence and associated factors of suicidal ideation and suicide attempts among adolescent and young adults in China from December 14, 2022 to February 28, 2023, when COVID-19 restrictions were lifted. Students in middle and high schools and colleges and universities in the province of Sichuan, China were asked to complete on-line cross-sectional surveys. Information was collected about sociodemographics, experiences related to the COVID-19 pandemic, suicidal ideation and suicide attempts. Participants also filled out the Patient Health Questionnaire-9, the Generalized Anxiety Disorder-7 and the Social Support Rate Scale surveys. Factors associated with suicidal ideation or suicide attempts were explored using logistic regression. Of the 82,873 respondents (aged 12 to 24 years), 21,292 (25.7%) reported having thought of suicide at least once in their lifetime, 10,382 (12.5%) reported having thought about suicide within the previous 12 months, and 1,123 (1.4%) reported having attempted it within the previous 12 months. Risk of lifetime suicidal ideation was higher among middle school students than among older students. Risk of suicidal ideation and risk of suicide attempts correlated directly with severity of symptoms of depression and anxiety, and inversely with level of social support. Greater risk of suicidal ideation and suicidal attempts was associated with: being female, living in an urban environment, attending a boarding school, currently being in love, having parents who divorced or remarried, having parents who exhibit non-authoritative parenting behavior, having higher family income, having been COVID-19 infected, having been quarantined for a long time, and being dissatisfied with one's education. Suicidal ideation and suicide attempts remain prevalent among young people in China. The potential associated factors identified in our study may be useful for targeting appropriate psychosocial interventions and developing mental health policies.

Relative frequencies and clinical features of Guillain-Barré Syndrome before and during the COVID-19 pandemic in North China

ObjectiveMost studies investigated the relationship between COVID-19 and Guillain-Barré syndrome (GBS) by comparing the incidence of GBS before and during the pandemic of COVID-19. However, the findings were inconsistent, probably owing to varying degrees of the lockdown policy. The quarantine requirements and travel restrictions in China were lifted around December 7, 2022. This study aimed to explore whether the relative frequency of GBS increased during the major outbreak in the absence of COVID-19-mandated social restrictions in China.MethodsGBS patients admitted to the First Hospital, Shanxi Medical University, from December 7, 2022 to February 20, 2023, and from June, 2017 to August, 2019 were included. The relative frequencies of GBS in hospitalized patients during different periods were compared. The patients with and without SARS-CoV-2 infection within six weeks prior to GBS onset formed the COVID-GBS group and non-COVID-GBS group, respectively.ResultsThe relative frequency of GBS among hospitalized patients during the major outbreak of COVID-19 (13/14,408) was significantly higher than that before the COVID-19 epidemic (29/160,669, P < 0.001). More COVID-GBS patients (11/13) presented AIDP subtype than non-COVID-GBS cases (10/27, P = 0.003). The mean interval between onset of infective symptoms and GBS was longer in COVID-GBS (21.54 ± 11.56 days) than in non-COVID-GBS (5.76 ± 3.18 days, P < 0.001).ConclusionsCOVID-19 significantly increased the incidence of GBS. Most COVID-GBS patients fell into the category of AIDP, responded well to IVIg, and had a favorable prognosis.

The local driving safety effect of motorcycle restrictions: Evidence from China

Motorcycles are a highly unstable element that impacts road traffic safety due to insufficient safety protection structures and poor maneuverability. The rapid increase in their use has exacerbated the severity of crash-related fatalities and injuries. While some countries have implemented motorcycle restrictions to address this phenomenon, the causal effect of such policies on reducing the severity of injuries from accidents requires further research. This study employs a difference-in-differences approach to estimate the causal effect of motorcycle restrictions in China on the severity of road crash injuries. The results indicate a significant reduction in the likelihood of fatal or severe injuries occurring in crashes. Specifically, in regions with motorcycle restrictions, the probability of crashes resulting in fatal or severe injuries decreased by 2.9% on average. The results remain robust following placebo and falsification tests and excluding confounding effects. Heterogeneity analysis reveals that motorcycle restrictions primarily affect male drivers and drivers with urban hukou, with no significant differences in effects across drivers of different age groups. Overall, the findings indicate that motorcycle restrictions reduce the number of motorcycles on the road and decrease the probability of motorcycle drivers being at fault in crashes, signifying improved driver behavior and effectively lowering crash severity.

Sufficient COVID-19 quarantine and testing on international travelers to forestall cross-border transmission after China's removal of the zero-COVID policy in early 2023

BackgroundRemoval of zero-COVID restrictions in China led to a surge in COVID-19 cases. In response, countries imposed restrictions on Chinese travelers. However, border policies imposed may not have been informed by accurate data and may not have provided substantial benefits. MethodsWe analyzed quarantines sufficient to prevent additional in-country transmission for February 13–19, 2023 based on World Health Organization (WHO) and self-reported infections to estimate prevalence. ResultsWe have shown that self-reported prevalence data indicated more stringent border restrictions compared to WHO-published prevalence statistics. No travel restrictions were required for Singapore, South Korea, and Japan so that infections would not be greater than with complete border closure. However, a 1-, 2-, and 3-day quarantine were indicated for England, Germany, and Scotland respectively. A 10-, 13-, and 14-day quarantine were required for Italy, France, and the Philippines, respectively, to prevent an increase in within-country infections due to travel. Vietnam and Thailand required a complete border shutdown. ConclusionOur results demonstrated the necessity for accurate and timely reporting of pandemic statistics to prevent an increase in viral spread. Through the minimum quarantine analysis, countries can use science to determine policy, minimize international friction, and improve the cost-efficiency of interventions.

Duration and severity of COVID-19 symptoms among primary healthcare workers: A cross-sectional survey.

This study aims to investigate the epidemiological characteristics of COVID-19 infection among healthcare workers, including the severity, duration of infection, post-infection symptoms and related influencing factors. A self-administered questionnaire was utilized to assess the post-infection status of primary healthcare workers in Jiangsu Province. The questionnaire collected information on demographic characteristics, lifestyle habits, post-infection clinical manifestations, work environment and recovery time of the respondents. Customized outcome events were selected as dependent variables and logistic regression models were employed to analyse the risk factors. Phi-coefficient was used to describe the relationship between post-infection symptoms. The analysis revealed that several factors, such as female, older age, obesity, previous medical history, exposure to high-risk environments and stress, were associated with a higher likelihood of experiencing more severe outcomes. On the other hand, vaccination and regular exercise were found to contribute to an earlier resolution of the infection. Among the post-infection symptoms, cough, malaise and muscle aches were the most frequently reported. Overall, there was a weak association among symptoms persisting beyond 14 days, with only cough and malaise, malaise and dizziness and headache showing a stronger correlation. The study findings indicate that the overall severity of the first wave of infection, following the complete lifting of restrictions in China, was low. The impact on primary healthcare workers was limited, and the post-infection symptoms exhibited similarity to those observed in other countries. It is important to highlight that these conclusions are specifically relevant to the population infected with the Omicron variant. This study helps to grasp the impacts of the first wave of COVID-19 infections on healthcare workers in China after the national lockdown was lifted. Primary healthcare workers in Jiangsu Province, including doctors, nurses, pharmacists and other personnel from primary healthcare units such as community health service centres and health centres.

The role of collectivism, liberty, COVID fatigue, and fatalism in public support for the zero-COVID policy and relaxing restrictions in China

BackgroundChina was the last country in the world to relax COVID-19 restrictions. A successful public health policy requires public support. This analysis examined the factors associated with Chinese support for zero-COVID and relaxing COVID-19 restrictions in China.MethodTwo online surveys were conducted among Chinese participants in mainland China on June 10–13 (N = 460) and December 2, 2022 (N = 450). These two samples were similar based on the participants’ demographics.ResultsThe results revealed that the perceived health consequences of a COVID-19 policy, perceived norms of approving a COVID-19 policy, and hope positively predicted the participants’ support for the COVID-19 policy. The results further showed that collectivism and fatalism positively predicted support for zero-COVID and negatively predicted support for relaxing restrictions. COVID fatigue was negatively associated with support for zero-COVID and positively associated with support for relaxing restrictions. Liberty positively predicted support for relaxing restrictions in June and negatively predicted zero-COVID in December 2023. It did not positively or negatively predict support for the policy adopted by the government.ConclusionCollectivism, liberty, COVID fatigue, and fatalistic beliefs are important considerations connected to public support for a COVID-19 policy. The role of liberty was more nuanced and depended on the survey’s time and whether the government adopted the policy.

Causal effect of aviation on air pollution: An instrumental variable from faraway COVID-19 restrictions in China

The causal impacts of aviation on local air pollution are poorly understood. Leveraging variation in aviation frequency caused by COVID-19 travel restrictions that occurred hundreds of miles away between 2020 and 2022, this study identifies the short-run effect of aviation on air pollution in Hangzhou, a Chinese megacity. The results demonstrate that a one standard deviation change in aviation is associated with 12% to 21.82% changes in ambient pollution concentrations, with even more substantial pollution effects on downwind days and flights departing from Hangzhou, respectively. These estimates also remain robust to alternative specifications, satisfy external validity beyond Hangzhou and the epidemic period, and exclude pollution spillover effects. We further quantify the welfare losses from aviation pollution and find that people are willing to pay 1.76 US dollars a day in per capita household income for reducing pollution caused by each standard deviation increase in flights (i.e., 134 flights). Further analysis reveals higher economic losses resulting from pollutants at international airports. Our results underscore the need to regulate airborne contaminants from aviation in China urgently.

A longitudinal analysis of the impact of the local tobacco retail availability and neighbourhood deprivation on male smoking behaviours in Shanghai, China

Some evidence from Western high-income countries suggests local tobacco retail availability and neighbourhood deprivation may influence smoking behaviours. However, this assertion has not been considered in China, where 44% of males continue to smoke. Data were analysed from Chinese males (n = 2054) who participated in Waves 3–5 (2009–2015) of the International Tobacco Control (ITC) China Survey by linking information on tobacco retail availability (estimated through population weighted Kernel Density of tobacco retailers in 2019) and neighbourhood deprivation (calculated as a composite score derived from the 2010 Chinese census) across Shanghai. Generalised Estimating Equation models were fitted to examine the impacts of local tobacco availability and neighbourhood deprivation on smoking behaviours (current smoking versus current non-smoking, quitting versus current smoking, longer durations of smoking abstinence versus current smoking) using the longitudinal data. Examining the impacts separately, participants living in neighbourhoods with greater availability and higher levels of deprivation were less likely to maintain longer durations of smoking abstinence in both unadjusted and adjusted models. Neighbourhood deprivation, but not availability, was found to be associated with higher odds of being a current smoker. Examining the impacts jointly, neighbourhood deprivation was still positively associated with current smoking and negatively associated with longer durations of smoking abstinence, but the negative association between availability and longer durations of smoking abstinence disappeared. The findings offer some evidence that greater tobacco retail availability and deprivation are obstacles on prolonged smoking cessation among males in Shanghai, China. Policymakers should consider small-area level place-based restrictions in China, such as reducing the availability of tobacco, as part of a comprehensive tobacco control strategy aimed at addressing the high prevalence of smoking.

Psychological status and related factors of resident physicians during the release of COVID-19 pandemic restrictions in China.

Resident physicians at the standardized training stage had undergone significant physical and mental stress during the release of the COVID-19 pandemic restrictions at the end of 2022 in China. This study aimed to investigate the psychological status (including anxiety, depression, somatic symptoms, job burnout, and vicarious trauma) of resident physicians and identify its influencing factors under these special periods. Survey was conducted one month after the release of the COVID-19 pandemic restrictions on resident training physicians from a tertiary first-class hospital in Zhejiang, China. Resident physicians completed the psychological status questionnaire. Chi-square tests, Mann-Whitney U tests, and logistic regression analyses were used to estimate the group differences and variable associations. The prevalence of anxiety, depression, and somatic discomfort in this study was 20.88, 28.53, and 41.47%, respectively. Female resident physicians were more likely to experience somatic symptoms [adjusted odds ratio (OR) = 2.36, 95% confidence interval (CI): 1.33-4.18]. Resident physicians with problem-focused coping styles were less prone to psychological health issues [depression (adjusted OR = 0.92, 95% CI: 0.88-0.96), anxiety (adjusted OR = 0.94, 95% CI: 0.90-0.98), somatic symptoms (adjusted OR = 0.93, 95% CI: 0.89-0.97), job burnout (adjusted OR = 0.91, 95% CI: 0.87-0.96) and vicarious trauma (adjusted OR = 0.94, 95% CI: 0.90-0.98)]. Inversely, resident physicians with emotion-focused coping styles and experienced negative life events were more prone to psychological health issues. Resident training physicians had a high risk of anxiety, depression, and somatic symptoms under the special COVID-19 pandemic restriction release period. Females, with lower training stages, degrees, negative life events, and emotion-focused coping styles had a disadvantaged effect on psychological status. The medical teaching management department needs to monitor and reduce the workload and working hours of resident physicians, ensure sufficient sleep time, and pay attention to the psychological status of resident physicians. By strengthening regular communication and mental health education or intervention, which can help them improve their ability to cope with complex tasks.

Effects of internet addiction and academic satisfaction on mental health among college students after the lifting of COVID-19 restrictions in China

BackgroundInternet addiction (IA) among students, worsened by Coronavirus disease 2019 (COVID-19) pandemic, has become a social problem with the digitalization of school learning and many aspects of daily life. However, few studies on IA have been conducted among students after the lifting of COVID-19 restrictions in China.MethodThis large-sample, cross-sectional, online survey was conducted to explore the characteristics of IA and the association among IA, academic satisfaction, and mental health problems from December 14, 2022 to February 28, 2023 in Sichuan, China. All participants (N = 22,605) were students in colleges and universities, recruited via their teachers and professors.ResultsOf all the participants, 14,921 (66.0%) participants had IA. Participants with IA were more likely to have depression symptom, anxiety symptom, insomnia, and lifetime suicidal ideation. In addition, participants with severe IA had significantly higher rates of mental health problems (e.g., depression, anxiety, insomnia, and suicidal ideation) than those with mild IA. A significant IA-by-academic satisfactory-interaction on mental health was identified: participants with higher level of IA showed particularly severe symptom of depression, anxiety and insomnia when affected by low satisfactory of academy (p &amp;lt; 0.001).ConclusionThis study reveals that IA has a significantly negative impact on mental health among college students after the lifting of COVID-19 restrictions in China. IA and academic satisfaction have interactive impacts on mental health problems among students. Further educational and health policies and psychosocial interventions should be developed to reduce IA and enhance academic satisfaction for improving students’ mental health.

Enhancing a sense of academic and social belongingness of Chinese direct-entry students in the post-Covid era: a UK context

ABSTRACT 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.

Do local governments capitalise on the spillover effect in the housing market? Quasi-experimental evidence from house purchase restrictions in China

This study used the house purchase restriction (HPR) policy applied between 2016 and 2017 in China to investigate whether local governments actively capitalised on the spillover effects induced by housing policy in adjacent cities. The difference-in-differences (DID) model was employed to estimate the spillover effects of HPR policy on land and bond markets for treatment cities and control cities. After implementation of the HPR policy, land conveyance area and land revenue in unregulated cities adjacent to regulated cities, increased by 32.4% and 47.3%, respectively, relative to nearby unregulated cities not adjacent to regulated cities. The issuance volume of urban investment bonds, which heavily relies on land price and revenue, in unregulated cities adjacent to regulated cities, increased by 163.5% in comparison with nearby control cities and the yield spread of newly issued bonds decreased. Overall, this study indicates that local governments actively capitalise on the spillover effects induced by housing policy in adjacent cities.

Academic performance and mental health among Chinese middle and high school students after the lifting of COVID-19 restrictions.

Although the COVID-19 pandemic has greatly changed the way students studied, it is still unknown about the impact of the COVID-19 pandemic on students' academic performance and mental health. To explore the academic performance and mental health status of middle and high school students after the lifting of COVID-19 restrictions in China. An online survey was conducted in Sichuan province, China from Dec 14, 2022 to Feb 28, 2023. All participants were students in middle and high schools, recruited via their teachers. The general information, COVID-19-related information, and academic performance were collected. The Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and Internet Addiction Test (IAT) were used to assess the mental health problems. Of 60,268 participants, 36,247 (60.2%) middle and high school students reported that their studies were affected by the COVID-19 pandemic, and 24,864 (41.2%) reported that their academic performance had worsened. The prevalence of depression and anxiety symptoms was 38.4 and 32.7%, respectively. There was a significant association between academic performance change and mental health problems. The logistic regression analysis showed that improved academic performance was a protective factor for depression, and declined academic performance was a risk factor for depression and anxiety. Being COVID-19 infected, family members being infected, with quarantine experience, and with COVID-19-related stigma were risk factors for depression and anxiety. Academic studies and mental health status of middle and high school students in Sichuan, China have been negatively impacted by the COVID-19 pandemic, even after the lifting of COVID-19 restrictions. Students' academic performance, academic concerns, and mental health status should be considered for educational policymakers and institutions to improve students' academic studies and mental well-being.

Positive effects of the COVID-19 pandemic on depression and anxiety in Chinese adolescents

The potential impact on mental health of home schooling and social isolation due to COVID-19 lockdowns has led to widespread concern, particularly for adolescents. However, studies including pre-pandemic data from longitudinal cohorts with an assessment of the longer-term impact of the Covid-19 pandemic beyond the first months of 2020 are scarce. This longitudinal study of 1534 adolescents attending a secondary school in Hunan province investigated self-reported symptoms of anxiety and depression using two validated scales (Screen for Child Anxiety Related Disorders, Child Mood and Feelings Questionnaire) at six time points before, during, and after the 2020 national lockdown restrictions in China. Perceived COVID-related stress was assessed by an author-developed scale at two timepoints during the lockdown. We investigated trends in symptoms over time with a fixed effects model and multiple imputations of missing data. Counter to our expectations, depressive and anxiety symptoms were reduced during the 2020 lockdown relative to pre-lockdown (depression: b = − 3.37, SE = 0.345, Cohen’s d = − 0.25, p < 0.0001; anxiety: b = − 4.55, SE = 0.382, Cohen’s d = − 0.30, p < 0.0001). Symptoms remained significantly reduced even after lockdown restrictions eased. Higher symptom levels during lockdown were associated with greater self-reported COVID-related stress (depression: b = 0.11, SE = 0.026, p < 0.0001; anxiety: b = 0.11, SE = 0.036, p < 0.0001). Although COVID-related stresses correlated with higher levels of anxiety and depression, the lockdown period was associated with improved symptom levels in the adolescents taking part in our study. School closures may have improved the mental health of adolescents in China. We speculate this beneficial effect of lockdown can be explained by the adverse effects of attending school itself such as exposure to bullying and achievement pressures.

Impacts of trading restrictions on price volatilities and speculative activities: Evidence from CSI 300 futures

Commonly trading restrictions have various impacts on asset prices and investors’ speculative activities. This study uses the unique trading restrictions in China from 2015 to 2017 to study how it affects the price volatilities and speculative activities of China Securities Index 300 (CSI 300) futures. To capture the daily price volatilities precisely, we apply four different measures incorporate opening, high, low, and closing prices. Speculative and hedging activities are calculated by using volume and open interest data. We find interesting evidence that trading restrictions decrease the price volatilities and the trading activities of speculators. However, though the trading restrictions have been eased since 2017, the speculators are still unwilling to participate in futures market immediately. Overall, the trading restrictions affect the price volatilities and speculative activities and provide the protection for the majority of investors, however, it also hinders the price discovery function of the futures market.

Insights from India’s Encounters with COVID-19

The uncertainties relating to the COVID-19 pandemic continue to pose extraordinary challenges to policymakers worldwide. The recent lifting of restrictions in China raised the spectre of another wave of infections beyond its borders, which has thankfully not occurred, so far. Now, three years after the pandemic emerged, policy assumptions and responses are being re-evaluated—from whether the virus emerged as a laboratory leak, to whether vaccines have efficacy, to whether Sweden’s laissez-faire approach was superior to other countries’ ambitious interventions. We examine India’s experience with COVID-19—impressionistically—to draw larger lessons for policymakers. India’s responses were a mix of hits and misses. Some measures helped contain the pandemic and assisted those in need. Other measures seemed performative—geared towards garnering glory on the global stage. Together, they throw light on the challenges of coping with a crisis in real time.
