The current study aimed to investigate the effects of school resumption on college students' mental health during the coronavirus disease 2019 (COVID-19) pandemic. We used the Perceived Stress Scale (PSS-10), Patient Health Questionnaire-9 (PHQ-9), and Self-Rating Anxiety Scale (SAS) to assess stress, depression, and anxiety, respectively, between same-age college students returning to school and those not returning to school. Of 1,598 students who completed the baseline survey (S1), 836 students completed a follow-up survey 10 months after school resumption (S2). There were statistically significant differences in stress and mild anxiety between male and female students ( p < 0.01). Comparison of PSS-10, PHQ-9, and SAS scores by perceived impact of COVID-19 showed significant differences (Welch test, p < 0.01). The correlation between PHQ-9 and SAS scores in school resumption and non–school resumption groups was relatively strong (adjusted R2 = 0.49 vs. 0.5). Multivariate linear regression showed that only PSS-10 ( p < 0.01) and SAS ( p < 0.05) scores significantly differed between returning and non-returning students. School resumption was an independent risk factor for PSS-10 and SAS scores. PSS-10, PHQ-9, and SAS scores were significantly higher in S1 than in S2 ( p < 0.01). During the COVID-19 pandemic, stress, anxiety, and depression were prevalent among college students; however, stress and anxiety were generally lower among college students returning to school than among non-returning students.

The incidence of ischemic cardiomyopathy (ICM) is increasing yearly, which seriously endangers human health. There is rarely any remarkable progress in the treatment of ICM from the available drugs. Recent research shows that natural herbal medicine may have beneficial effects in the prevention and treatment of cardiovascular diseases. The effective extracts of the herbs may improve myocardial ischemia through various actions, such as hemodynamic, hemorheological, and vascular actions, and on various cell biology aspects, such as intracellular calcium balance, mitochondria function, cell apoptosis, and scavenging free radicals. Here, we review the animal research progress and potential mechanisms in the treatment of ICM using extracts of well-known traditional Chinese herbal medicines.

The development of robust damage detection methods for offshore structures is crucial to prevent catastrophes caused by structural failures. In this research, we developed an Improved Modal Strain Energy (IMSE) method for detecting damage in offshore platform structures based on a traditional modal strain energy method (the Stubbs index method). The most significant difference from the Stubbs index method was the application of modal frequencies. The goal was to improve the robustness of the traditional method. To demonstrate the effectiveness and practicality of the proposed IMSE method, both numerical and experimental studies were conducted for different damage scenarios using a jacket platform structure. The results demonstrated the effectiveness of the IMSE method in damage location when only limited, spatially incomplete, and noise-polluted modal data is available. Comparative studies showed that the IMSE index outperformed the Stubbs index and exhibited stronger robustness, confirming the superiority of the proposed approach.

From the perspective of the effectiveness of internal control, according to the Stakeholder Theory, Principal-Agent Theory and Reputation Theory, this paper analyzes comparatively the influences of internal control on the assumption of corporate social responsibility (SCPS) from the accrual basis, and the fulfillment of corporate social responsibility (CSRF) from the cash flow system respectively. Using a sample of 1767 firms listed in China between 2011 and 2016, we find that effective internal control has significantly promoted enterprises to assume social responsibilities. Meanwhile, effective internal control substantially improves the fulfillment of corporate social responsibility. This study overcomes the current situation that the two concepts of assumption and fulfillment of corporate social responsibility have not been distinguished in previous literature. We suggest that, in the economic transition period, the positive role of internal control in corporate governance should be promoted to protect the legitimate rights and interests of stakeholders, the adverse impact of the principal-agent relationship between shareholders and management on corporate governance should be avoided, building high-quality internal control, enterprises achieve steady and sustainable development process by the positive reputation value and robust external monitoring mechanism. This research is of practical importance to strengthen the subsequent construction of the internal control system and the long-term practice of corporate social responsibility.

Although the relationship between board gender diversity and a firm&rsquo, s financial performance has been investigated before, the current study provides a valuable contribution by exploring the complex phenomenon of the mediating impact of corporate social responsibility (CSR) performance on a firm&rsquo, s financial performance. The current study aims to explore whether corporate social responsibility (represented by the proxy variable of CSR reporting) mediates the relationship between boardroom gender diversity and firm performance. We use the pooled ordinary least square (OLS) regression to examine the above relationship by using data from 2008 to 2015. To control the likelihood of endogeneity we also use one-year lagged and two-stage least square (2SLS) regression models. Our results show that boardroom gender diversity is significant, positively correlated with firm performance, and CSR fully mediates the relationship between boardroom gender diversity and firm performance. In addition, four control variables (independent director, Chief executive officer (CEO power), board member meeting frequency, Big4, and leverage) have some influence on firm performance. These findings hold for a set of robustness tests. Our findings have the implication for the investors and regulators. For investors, our results show that the existence of female directors on the board can improve the firm performance. For regulators, our results advise the worldwide policy maker to give the importance to boardroom gender diversity. The paper contributes to the existing studies, by pioneering the investigations of the mediating role of CSR in the relation between boardroom gender diversity and firm performance in Chinese context.

This study aims to investigate whether firm performance influences corporate social responsibility reporting of Chinese listed companies. We have used the sample of all A-share listed firms on Shenzhen and Shanghai stock exchanges for the period 2008 to 2015. The authors used pooled ordinary least squares (OLS) regression as a baseline methodology. To control the possible problem of endogeneity we use one year lagged and two-stage least squares regression. We find that firm performance has a statistically significant impact on CSR reporting. Moreover, we see that firms with high performance are more likely to report CSR activities than low-performance firms. Additionally, five of the control variables (board size, CEO power, SOE, firm size, and Big4) have some influence on CSR reporting. These findings hold for a set of robustness tests. Our results have implications for the development of CSR reporting in developing countries like China. Our research suggests that, in China, companies with better financial performance undertake more CSR reporting. The paper contributes to the existing literature by investigating the effect of firm performance on CSR reporting of Chinese listed companies. Additionally, this paper enriches the current literature on CSR reporting and highlights the importance of a firm&rsquo, s financial performance for better environmental performance and reporting.

Lung cancer is one of the most prevalent types of cancer, but accurate diagnosis remains a challenge. The aim of the present study was to create a model using amino acids and acylcarnitines for lung cancer screening. Serum samples were obtained from two groups of patients with lung cancer recruited in 2015 (including 40 patients and 100 matched controls) and 2017 (including 17 patients and 30 matched controls). Using a metabolomics method, 21 metabolites (13 types of amino acids and 8 types of acylcarnitines) were measured using liquid chromatography-tandem mass spectrometry. Data (from the 2015 and 2017 data sets) were analysed using a Mann-Whitney U test, Student's t-test, Welch's F test, receiver-operator characteristic curve or logistic regression in order to investigate the potential biomarkers. Six metabolites (glycine, valine, methionine, citrulline, arginine and C16-carnitine) were indicated to be involved in distinguishing patients with lung cancer from healthy controls. The six discriminating metabolites from the 2017 data set were further analysed using Partial least squares-discriminant analysis (PLS-DA). The PLS-DA model was verified using Spearman's correlation analysis and receiver operating characteristic curve analysis. These results demonstrated that the PLS-DA model using the six metabolites (glycine, valine, methionine, citrulline, arginine and C16-carnitine) had a strong ability to identify lung cancer. Therefore, the PLS-DA model using glycine, valine, methionine, citrulline, arginine and C16-carnitine may become a novel screening tool in patients with lung cancer.

Improving collaboration among organizations is a goal of interagency educational teams, but collaboration is typically thought of as an ambiguous concept that cannot be quantified. To assess the collaborative strength of a state-level interagency team in a Midwestern state, team members completed the Levels of Collaboration Scale (Frey et al., American Journal of Evaluation 27(3):383, 2006) for three consecutive years. The team members then utilized the results of the social network analysis to support and sustain collaborative efforts. Findings revealed that the number of partnerships increased and the depth of collaboration expanded across the 3 years. Social network analysis results were utilized to develop collaboration strategies, thus influencing the expansion of the network across the 3-year period.

BACKGROUND This study observed the efficacy of ultrasonic technique with out-of-plane orientation and in-plane guidance in radial artery puncture and cannulation in intensive care unit (ICU) shock patients to elucidate the effect of this technique on the security of cannulation. MATERIAL AND METHODS A total of 88 ICU shock patients, randomized into a palpation (control) group and an ultrasound (experimental) group, received continuous intravenous sedation and analgesia. The palpation group patients underwent radial artery cannulation using the traditional palpation pulsation approach, and the ultrasound group patients underwent radial artery cannulation under out-of-plane orientation and in-plane guidance using an ultrasonic apparatus. Data were recorded and compared between the 2 groups. RESULTS (1) The success rate of the first puncture in the ultrasound group and the palpation group was 80% and 42%, respectively (P

Because of their unique design, web-sever clusters have gained much attention and have become increasingly popular for handling requests. When handling large amounts of complex data, load-balancing is a crucial necessity. This paper proposes the implementation of real time monitoring status of tasks and dynamic dispatch strategy in web-sever cluster systems. It devises the multiple priority queues and a redo mechanism for effectiveness and reliability. Implementation of the system is based on Twisted Framework

The serial scandals of Chinese conglomerates in 2009 say that the risk management mechanism is very weak and is urgent to build a set of reasonable risk control system. This article mainly suggests a new framework to improve the risk management mechanism of state -owned conglomerates from the independent director system perspectiv.

BACKGROUND: It has been reported that the prevalence of chronic diseases is high among old people and they have poor chronic diseases knowledge. This study was therefore designed to evaluate the awareness rate of chronic diseases knowledge among people aged over 60 years, to explore its related factors and to provide evidence for future health education. METHODS: A cross-sectional study was conducted from April to August in 2011. People aged 60 years and above from 3 communities in Jinan were selected by cluster sampling. Nine hundred and twenty five participants were interviewed face-to-face using a structured questionnaire. RESULTS: The awareness rates of chronic diseases knowledge varied from 29.5% to 90.2%. Four healthy lifestyles including quitting smoking and less drinking, keeping broad-minded, maintaining balanced diet and moderate physical activity were best known (from 86.3% to 90.2%). The least known knowledge were 2 complications of hypertension: nephropathy (29.5%) and retinopathy (37.2%). Participants with the following characteristics or behaviors were more likely to have higher chronic diseases knowledge: younger age, female, Han Chinese, higher level of education, having health insurance, participating in societies, having family history of chronic diseases, frequently gathering with friends/relatives, usually going to provincial hospitals/hospitals affiliated with medical universities, usually going to municipal hospitals and usually going to community health center/station. CONCLUSIONS: Old people in Jinan had incomplete chronic diseases knowledge and the overall awareness rate was not high. The older people's chronic diseases knowledge should be improved and health education programs should target males, older people with lower educational level, having no health insurance, having no family history of chronic diseases, participating in no societies, and less frequently gathering with friends/relatives. Also, lower level medical facilities should improve their skills of health education.
