Research on the Organizational Development Model for Intercultural Communication Competence

On the basis of the three factors theory composed of knowledge, motivation and skills in intercultural communication competence, constructed index system of intercultural communication competence. Through the survey of 350 DL University’s undergraduates, the overall level of their intercultural communication competence is 3.34 by SPSS software，Knowledge factor, motivation factor and skills factor are 3.16, 3.62 and 3.24. The data shows that the DL University’s undergraduates’ intercultural communication competence is at the medium level，and the attitude or requirement of the undergraduates in DL University to expect or participate in intercultural communication are relatively strong, but the knowledge and skills of intercultural communication are inefficient. Finally, put forward the organizational development model with the integration of knowledge, motivation and skills based on the data analysis results

The Dynamic Relationship between Stock Market and Macroeconomy at Sectoral Level: Evidence from Chinese and US Stock Market

As a most important component of capital market, stock market has always been regarded as the “barometer” of macroeconomy. However, many researchers have found that the stock market is not always in the lead, especially for the emerging markets, and the leading role of different sector indices is also different for the corresponding sectors. From the perspective of a comparison between mature market and emerging market at sectoral level, this paper utilizes the thermal optimal method to examine the dynamic lead-lag relationships between stock sector indices and macroeconomic variables for the USA and China. The results show that, for the US stock market, three sector indices including consumption, industry, and real estate have been leading the corresponding macroeconomic variables since 2013; for the Chinese stock market, the lead-lag relationships are different for these sectors. The real estate sector index and the industry sector index have been leading the corresponding macroeconomic variables since 2010, and the lead-lag relationship between the consumption sector index and the total retail sales is not always positive or negative, which means that the consumption sector index does not always lead the total retail sales. The empirical results confirm that the “barometer function” of immature stock market is still weak and easier to be disabled by factors such as irrational market sentiment

The Evolution Characteristics of Systemic Risk in China’s Stock Market Based on a Dynamic Complex Network

The stock market is a complex system with unpredictable stock price fluctuations. When the positive feedback in the market amplifies, the systemic risk will increase rapidly. During the last 30 years of development, the mechanism and governance system of China’s stock market have been constantly improving, but irrational shocks have still appeared suddenly in the last decade, making investment decisions risky. Therefore, based on the daily return of all a-shares in China, this paper constructs a dynamic complex network of individual stocks, and represents the systemic risk of the market using the average weighting degree, as well as the adjusted structural entropy, of the network. In order to eliminate the influence of disturbance factors, empirical mode decomposition (EMD) and grey relational analysis (GRA) are used to decompose and reconstruct the sequences to obtain the evolution trend and periodic fluctuation of systemic risk. The results show that the systemic risk of China’s stock market as a whole shows a downward trend, and the periodic fluctuation of systemic risk has a long-term equilibrium relationship with the abnormal fluctuation of the stock market. Further, each rise of systemic risk corresponds to external factor shocks and internal structural problems

Iodine nutrition and the prevalence of thyroid disease after salt iodization: a cross-sectional survey in Shanghai, a coastal area in China.

BACKGROUND: Both insufficient and excess iodine may produce thyroid disease. After salt iodization in China, the median urine iodine concentration (UIC) of children aged 8-10 years appeared adequate. However, it is unknown whether dietary changes due to rapid economic development in Shanghai have affected whole population iodine nutrition. OBJECTIVE: To assess dietary iodine intake, UIC and the prevalence of thyroid disease in the general population of Shanghai. DESIGN: A cross-sectional survey was conducted with general participants aged 5-69 years (n = 7,904) plus pregnant and lactating women (n = 380 each) selected by stratified multistage sampling. The iodine concentrations in their salt, drinking water and urine were measured. Daily iodine intake was estimated using the total diet study approach. Serum thyroid hormone concentrations and thyroid-related antibodies were measured and thyroid ultrasonography was performed. RESULTS: The median iodine concentration in salt was 29.5 mg/kg, and 12.8 µg/L in drinking water. Iodized salt, used by 95.3% of participants, contributed 63.5% of total dietary iodine. Estimated daily iodine intake was 225.96 µg. The median UIC of general participants was 146.7 µg/L; UIC <100 µg/L (iodine insufficiency) was seen in 28.6%; UIC >300 µg/L (iodine excess) in 10.1%. Pregnant women had a median UIC of 135.9 µg/L, with UIC <150 µg/L in 55.4%. Thyroid nodules and subclinical hypothyroidism were found in 27.44% and 9.17%, respectively. CONCLUSIONS: According to published criteria, the current dietary iodine intake in Shanghai was generally sufficient and safe, but insufficient in pregnant women. Thyroid nodules and subclinical hypothyroidism were the commonest thyroid diseases identified

Trendelenburg position for acute anterior circulation ischaemic stroke with large artery atherosclerosis aetiology (HOPES 3): rationale and design

Rationale The effect of the head position as a non-pharmacological therapy on acute ischaemic stroke (AIS) remains inconclusive. Our recent Head dOwn-Position for acutE moderate ischaemic Stroke with large artery atherosclerosis (HOPES 2) suggested the safety, feasibility and potential benefit of the head-down position (HDP) in AIS.Aim To investigate the benefit of HDP in acute moderate ischaemic stroke patients with large artery atherosclerosis (LAA).Sample size estimates Based on a two-sided 0.05 level of significance, 600 patients are expected to yield the superiority hypothesis with 80% power, stratified by age, sex, history of diabetes, baseline systolic blood pressure, location of index vessel, National Institutes of Health Stroke Scale Score at randomisation, onset to randomisation time, progression to moderate neurological deficit due to early neurological deterioration and degree of responsible vessel stenosis.Design Head dOwn-Position for acutE moderate ischaemic Stroke with large artery atherosclerosis(HOPES 3) is a prospective, randomised, open-label, blinded endpoint and multicentre study. Eligible patients who had an ischaemic stroke will be randomly assigned (1:1) into the HDP group receiving −20° Trendelenburg plus standard medical care in compliance with national guidelines, or control group only receiving standard medical care in compliance with national guidelines.Outcome The primary outcome is favourable functional outcome, defined as modified Rankin Scale 0–2 at 90 days. Safety outcomes are HDP-related adverse events. All outcomes will have blinded assessment and will be analysed on the intention-to-treat basis.Conclusions The results of HOPES 3 will provide evidence for the effect of HDP in acute moderate ischaemic stroke patients with LAA within 24 hours of onset or in patients with progression from mild neurological deficit within 24 hours.Trial registration number NCT06010641

Exploring the landscape, hot topics, and trends of bariatric metabolic surgery with machine learning and bibliometric analysis

Background: This study aimed to analyze the landscape of publications on bariatric metabolic surgery through machine learning and help experts and scholars from various disciplines better understand bariatric metabolic surgery’s hot topics and trends. Methods: In January 2021, publications indexed in PubMed under the Medical Subject Headings (MeSH) term ‘Bariatric Surgery’ from 1946 to 2020 were downloaded. Python was used to extract publication dates, abstracts, and research topics from the metadata of publications for bibliometric evaluation. Descriptive statistical analysis, social network analysis (SNA), and topic modeling with latent Dirichlet allocation (LDA) were used to reveal bariatric metabolic surgery publication growth trends, landscape, and research topics. Results: A total of 21,798 records of bariatric metabolic surgery–related literature data were collected from PubMed. The number of publications indexed to bariatric metabolic surgery had expanded rapidly. Obesity Surgery and Surgery for Obesity and Related Diseases are currently the most published journals in bariatric metabolic surgery. The bariatric metabolic surgery research mainly included five topics: bariatric surgery intervention, clinical case management, basic research, body contour, and surgical risk study. Conclusion: Despite a rapid increase in bariatric metabolic surgery–related publications, few studies were still on quality of life, psychological status, and long-term follow-up. In addition, basic research has gradually increased, but the mechanism of bariatric metabolic surgery remains to be further studied. It is predicted that the above research fields may become potential hot topics in the future

The Association of Dietary Cholesterol and Fatty Acids with Dyslipidemia in Chinese Metropolitan Men and Women

Background: The associations between dietary cholesterol and fatty acids and serum lipids are controversial. This study is to examine the association of dietary cholesterol and fatty acids with serum lipids and dyslipidemia in Chinese metropolitan male and female adults. Methods: 3850 participants in the Shanghai Diet and Health Survey were investigated during the period 2012&ndash;2013. Information was obtained on dietary intake, anthropometric and blood laboratory measurements. Dyslipidemia was determined by US National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III). Results: Dietary cholesterol was in line with serum TC, LDL-C and the LDL-C to HDL-C ratio in general and the partial correlation coefficients were 0.64 (95% CI: 0.13&ndash;1.15, p = 0.015), 0.73 (95% CI: 0.21&ndash;1.24, p = 0.006) and 0.01 (95% CI: 0.00&ndash;0.02, p = 0.018), respectively. The partial correlation coefficients were greater in women. Dietary fatty acids were not associated with serum lipids. The highest quintile of dietary cholesterol intake (&ge;538.0 mg/day) was associated with an approximate 1.6-fold risk for high TC and high HDL-C compared with the lowest quintile (&lt;193.1 mg/day) generally. Conclusions: Dietary cholesterol was associated with serum cholesterol in Chinese metropolitan adults and a higher risk of dyslipidemia was observed at a high level of dietary cholesterol intake. Whether there should be an upper limit on dietary cholesterol in the Chinese population warrants further study
