The COVID-19 pandemic has radically changed and disrupted education; colleges and universities have closed their campuses, and many have shifted to online courses. In the pre-pandemic era, online classes were associated with several benefits and challenges, and the pandemic might have brought additional benefits and obstacles. This research examined students' perceptions of online classes during the pandemic. The study looked at four aspects: perceived benefits of online classes; perceived challenges; beliefs and an overall evaluation; and potential improvements. An online questionnaire was administrated to some first- and second-year undergraduate students at a College in China. It combined a set of 23 closed-ended and open-ended questions and 342 valid and complete responses were collected. Perceived benefits included creating a digital learning community, improving students' digital learning skills, and staying connected during tough times. Challenges comprised adaptability issues due to the sudden shift to online classes, time-management issues, being distracted by social media plus technological obstacles. Regarding beliefs, students believed that a blended model that combines both classroom and online modes is necessary for the post-pandemic era. To enhance the sustainability of online classes in the post-pandemic era, a set of improvements are explored and suggested.

This 2-year longitudinal study examined relations between enjoyment of learning in Chinese and mathematics, two major subjects in Chinese schools, and indexes of school performance. The participants included 1041 students (501 boys) initially in third, fifth, and seventh grades (mean age = 10.49 years) in China. Data on enjoyment of Chinese and mathematics were collected from students' self-reports and data on school performance were collected from multiple sources in 2017 and 2019. The results showed that enjoyment of mathematics positively predicted later academic achievement, self-perceptions of academic competence, teacher-rated school competence, and peer-assessed leadership-social competence. Enjoyment of Chinese negatively predicted later mathematics achievement and self-perceptions of academic competence and nonsignificantly predicted other school performance variables. The results were discussed in Chinese context.

This 1-year longitudinal study examined the effects of academic performance and depression in friendships among elementary school children in China. Participants included 1122 children (44% boys) within 561 stable friendship dyads initially in fourth and fifth grades (initial M[subscript age] = 11 years). Data on academic performance, depression, and friendship were collected from multiple sources in the period of 2012 to 2014. Dyadic analysis using the actor-partner interdependence model showed that friends' academic performance significantly and positively predicted children's later academic performance, indicating same-domain effects, and significantly and negatively predicted children's later depression, indicating cross-domain effects, with a medium effect size ([epsilon][subscript 3] = 0.70) for the effects of academic performance. The results help understand the role of friendship in children's development in the Chinese context.

The primary purpose of the present study was to examine the contributions of social, academic, and psychological characteristics of peer groups to individual development in the same and different domains in Chinese children. Participants included 1,864 elementary school students (945 boys, M[subscript age] = 11 years) in China. One-year longitudinal data on social competence, academic functioning, and psychological problems were obtained from peer nominations, teacher ratings, school records, and self-reports. Multilevel structural equation modeling analysis showed that group-level social competence, academic performance, and psychological problems had significant same-domain effects on later individual outcomes. Moreover, group-level social competence had a positive cross-domain effect on later individual academic performance and a negative cross-domain effect on later individual psychological problems. Group academic performance had a positive cross-domain effect on later individual social competence, and group psychological problems had a negative cross-domain effect on later individual social competence. The results suggest that affiliation with peer groups, particularly socially competent groups, may have pervasive implications for children's performance and adjustment from a developmental perspective.

This study examined toddlers' autonomy- and connectedness-oriented behaviors and mothers' encouragement of autonomy and connectedness in two cohorts (1995 and 2008) in urban China. Observational data were collected from Chinese children and their mothers in a laboratory free play session. The results showed that compared with children in the 1995 cohort (207 children, 95 boys, M[subscript age] = 24.09 months), children in the 2008 cohort (281 children, 144 boys, M[subscript age] = 24.34 months) displayed fewer connectedness-oriented behaviors and spent more time on autonomous activities. Compared with mothers in the 1995 cohort (45% with a college education), mothers in the 2008 cohort (43.4% with a college education) were less likely to display involvement in children's activities and more likely to encourage child autonomy. The results suggest that macrolevel contexts may play an important role in shaping parenting and children's behaviors.

Indiscriminate friendliness (IF) is a prominent issue with children adopted from China to the United States. Through a mixed methods design, the authors explored four Chinese adoptees' experiences of IF within their real-life context, investigated potential factors associated with IF, and examined the IF-attachment relationship. This mixed methods study consisted of a qualitative case study of four children adopted from China and a quantitative investigation into IF using a sample of 92 adoptive parents with Chinese adoptees. The qualitative findings revealed crucial propositions related to children's IF, and the quantitative results provided further evidence to corroborate the qualitative findings. This study reinforced the stance that IF should be treated as a distinct construct from attachment. Researchers and professional counselors can benefit from the results of this study to better serve Chinese adoptive families.

This study aims to provide an overview of RECs (research ethics committees) in Chinese universities, encompassing both medical and non-medical studies. The primary objective is to identify major challenges faced by RECs in Chinese universities and draw meaningful implications from the findings. The investigation focuses on 42 comprehensive Chinese universities, and the results reveal that while all universities have implemented RECs in various forms, only 28.6% explicitly stipulate ethical review requirements for non-medical disciplines. Furthermore, RECs in Chinese universities encounter various challenges, including insufficient attention to research ethics review, inadequate ethics review systems and regulations, a lack of education and training, and lacking ethics review for non-medical research. This paper proposes recommendations for establishing robust RECs in Chinese universities, seeking to enhance ethical governance in research. By addressing the challenges identified, these recommendations aim to strengthen ethical oversight, foster a culture of responsible research, and uphold the highest ethical standards across diverse academic disciplines.

Although studies have focused on intergroup biases (e.g., discrimination) during the COVID-19 pandemic, little is known about the underlying mechanisms driving intergroup bias, specifically social categorization. In-depth interviews were conducted among 32 residents of Wuhan, P.R. China, during and after the initial COVID-19 lockdown (Jan-July, 2020). Interpretative phenomenological analysis (IPA) was applied to describe perceived prejudice and discrimination and the intergroup interaction processes. Results indicated that: (1) Wuhan residents' interpretations of perceived prejudice and discrimination evolved over time, especially regarding views of the pandemic prevention measures; (2) intergroup contact, emotional factors and cognitive factors influenced individuals' perceptions of prejudice and discrimination; (3) social categorization and integration processes underwent changes across different stages of the COVID-19 pandemic in Wuhan, encompassing the lockdown and reopening; (4) the group identity of recovered COVID-19 patients was easily solidified; (5) in the group integration process, emphasizing common attributes between groups, individualized media coverage and positive aspects of intergroup interactions weakened intergroup boundaries and promoted group integration. These results enrich existing knowledge about perceived discrimination and social categorization processes of a suddenly marginalized group through qualitative research methods.

Background: The prevalence of steatotic liver disease (SLD) in patients with type 2 diabetes (T2DM) exceeds 50%. This study aimed to investigate the clinical characteristics of SLD and liver fibrosis in Chinese patients with T2DM. Methods: Inpatients from 2021 to 2023 were included in the study. Fatty liver index (FLI) and fibrosis-4 (FIB-4) were calculated to assess hepatic steatosis and fibrosis respectively. Statistical analysis was completed by SPSS v25 and GraphPad Prism v8.0.1. Results: Of the 1466 participants, about one-third of the patients in T2DM-SLD group were diagnosed with liver fibrosis (LF), and the percentage of patients over 50 years old was 85.9%. Patients with SLD had higher levels of BMI, blood pressure, liver enzymes, fasting blood glucose (FBG), HbA1c, C-peptide, total cholesterol (TC) and triglyceride (TG) (P<0.05 for all). Patients with liver fibrosis had lower TC, TG, hemoglobin (Hb), erythrocyte count (RBC), leukocyte count (WBC) and platelet (PLT) levels (P<0.05 for all). Compared with simple T2DM and SLD-NLF (non-liver fibrosis) groups, for patients over 50 years old, the prevalence of coronary heart disease, stroke, tumor, and diabetic nephropathy was higher in patients with liver fibrosis. Liver fibrosis might be the risk factor of arterial stiffness, stroke, coronary heart disease and numbness based on multivariable logistic regression analysis. Conclusion: Hepatic steatosis and fibrosis were common in patients with T2DM. Liver fibrosis was relevant to many macrovascular and microvascular diabetic complications. [ABSTRACT FROM AUTHOR]

Background: Adherence to the World Health Organization's 24-hour movement behavior (24-HMB) guidelines is associated with various health outcomes. However, its relationship with bone mineral density (BMD) in young children has not been investigated. This study aimed to examine the cross-sectional and longitudinal associations between adherence to the 24-HMB guidelines and BMD in young children. Methods: A total of 120 children aged 3–5 years were recruited from three kindergartens in Changsha, Hunan, China. Physical activity (PA) was objectively measured using ActiGraph wGT3X-BT accelerometers, and BMD was assessed using the Sunlight Omnisense 7000P ultrasound device. Screen time (ST) and sleep duration (SD) were reported by parents. Logistic regression was used to analyze the associations between guideline adherence and BMD. Results: Only 5.5% of the participants met all three guidelines for PA, ST, and SD, while 16.5% did not meet any. In the cross-sectional analysis, young children who met both ST and SD guidelines (OR = 0.29, 95% CI: 0.09, 0.95) had a lower risk of insufficient BMD compared to those who met none. In the one-year cohort follow-up, young children who met the PA guideline at baseline (OR = 0.22, 95% CI: 0.07, 0.71), as well as those who met both the PA and ST guidelines (OR = 0.18, 95% CI: 0.04, 0.83) or all three (OR = 0.13, 95% CI: 0.03, 0.69), had a lower risk of insufficient BMD at one year. Conclusions: Adherence to the 24-HMB guidelines may promote bone health in young children. Future research should prioritize achievable goals, such as limiting ST and ensuring adequate SD, while gradually increasing MVPA to optimize bone development. [ABSTRACT FROM AUTHOR]

This study examined relations between behavioral inhibition in toddlerhood and social, school, and psychological adjustment in late adolescence in China. Data on behavioral inhibition were collected from a sample of 2-year-olds (initial N = 247). Follow-up data were collected at 7 years for peer relationships and 19 years for adjustment across domains. The results showed that early inhibition positively predicted later social competence and school adjustment. Peer relationships in middle childhood served as a protective factor in the development of depression of inhibited children. The results indicate the distinct functional meaning of behavioral inhibition in the Chinese context from a developmental perspective.

Background: Intensive Care Unit nurses are related to the medical quality and life outcome of critically ill patients. In the context of nurse shortage, it is of great significance to reduce the turnover intention of Intensive Care Unit nurses. Inclusive Leadership, organizational-based self-esteem and Interactional Justice are important factors affecting the turnover intention of Intensive Care Unit nurses. However, for the special group of Intensive Care Unit nurses, there are few studies that explore the associations between these factors. This study explores the effect of inclusive leadership on the turnover intention of Intensive Care Unit nurses and the potential mediation through organizational-based self-esteem and interactional justice. Method: A cross-sectional study design was used to investigate 460 Intensive Care Unit nurses in 4 general hospitals in northern China. The scales used in this study include the inclusive leadership scale, the organization-based self-esteem scale, the interactional justice scale and the turnover intention scale. SPSS 27.0 was used for descriptive analysis and Pearson correlation analysis. AMOS 25.0 was used to construct structural equation model and Bootstrap test. Results: The results showed that the turnover intention of Intensive Care Unit nurses was higher (2.05 ± 0.67). Inclusive leadership had a negative predictive effect on turnover intention (β=-0.27, P < 0.001), and organizational-based self-esteem and interactional justice played a chain mediating role in the relationship between them (β=-0.051, P < 0.05). Conclusions: Inclusive leadership is significantly related to the turnover intention of Intensive Care Unit nurses, and organizational-based self-esteem and interactional justice play a chain mediating role between the two. When medical institutions and nursing managers intervene to reduce the turnover intention of Intensive Care Unit nurses, they should not only focus on inclusive leadership but also consider the impact of organizational-based self-esteem and interactional justice on turnover intention, in order to develop effective talent retention strategies.

The perception of the value of children (VOC) can elucidate why individuals consider it beneficial to have children by uncovering their subjective intentions and experiences regarding their fertility decisions. Using VOC perceptions to understand fertility change in the modernization process, this qualitative study explores how parents' VOC change meshes with China's socioeconomic and cultural contexts. This article examines intergenerational VOC evolution under the support and constraints of socioeconomic environments and cultural norms. Grandparents, embedded in the rural economy and traditional culture, exhibit economic/utilitarian and social/normative VOC. Young parents, living, and having grown up in urban economic and modernized cultural contexts, recognize emotional/psychological VOC for fertility intention. Migrant parents living in urban economies but bound by traditional culture believe that social/normative VOC is important for fertility intention. The results advance understanding of the integration of individuals' psychological intentions with the socioeconomic-cultural contexts that influence their fertility and VOC. [ABSTRACT FROM AUTHOR]

Leadership in peer groups is an important issue in adolescent socioemotional development, yet it has received limited attention in research. This one-year longitudinal study examined peer group leadership and the roles of social, academic, and psychological characteristics in the dynamics of group leadership. Participants included 1061 Chinese students (initial mean age =11.17 years; SD = 6.98 months; 49.4% female). Data were collected from peer assessments, teacher ratings, and self-reports. The longitudinal social network analysis (SIENA) indicated that peer group leadership was fluid with leadership status evolving over time across groups in a hierarchical manner. Adolescents displaying higher social competence and aggression and lower shyness were more likely to become group leaders. Academic performance and loneliness were not significantly associated with the dynamics of peer group leadership. The results help understand peer group leadership and contributions of social behaviors to the attainment of leadership status in peer groups in early adolescence. [ABSTRACT FROM AUTHOR]

Background: Due to the high prevalence of multimorbidity and realistic health service demands for fall prevention, there is growing interest in the association between multimorbidity and falls. Our study aimed to identify multimorbidity patterns among Chinese older adults and explore the association between multimorbidity patterns and falls. Methods: Data from 4,579 Chinese community-dwelling older adults was included in this analysis. Information regarding falls and 10 chronic conditions was collected. An exploratory factor analysis was performed to determine multimorbidity patterns. Regression models were fitted to explore the associations of individual chronic disease or multimorbidity patterns with falls. Results: Among 4,579 participants, 368 (8.0%) were defined as fallers, including 92 (2.0%) frequent fallers, and multimorbidity affected 2,503 (54.7%) participants. Older adults with multimorbidity were more likely to be fallers [odds ratio (OR) = 1.3, P = 0.02] and frequent fallers (OR = 1.7, P = 0.04). Three multimorbidity patterns were identified (i.e., cardiovascular-metabolic diseases, psycho-cognitive diseases and organic diseases), and the associations between psycho-cognitive diseases/organic diseases and prevalent falls or frequent falls were found to be significant. Conclusions: The psycho-cognitive disease pattern and organic disease pattern are significantly associated with falls. Therefore, more attention should be paid to patients with psycho-cognitive diseases and timely, targeted diagnostic and treatment services should be provided in fall prevention.

The canopy of perennial evergreen fruit trees in southern China has a unique Bidirectional Reflectance Factor (BRF) due to its complex multi-branch structure and density changes. This study aimed to address the lack of clarity regarding the changes in BRF of evergreen fruit trees in southern China. Litchi, a typical fruit tree in this region, was chosen as the subject for establishing a three-dimensional (3D) real structure model. The canopy BRF of litchi was simulated under different leaf components, illumination geometry, observed geometry, and leaf area index (LAI) using a 3D radiation transfer model. The corresponding changes in characteristics were subsequently analyzed. The findings indicate that the chlorophyll content and equivalent water thickness of leaves exert significant influences on canopy BRF, whereas the protein content exhibit relatively weak effects. Variation in illumination and observation geometry results in the displacement of hotspots, with the solar zenith angle and view zenith angle exerting significant influence on the BRF. As the LAI of the litchi orchard increases, the distribution of hotspots becomes more concentrated, and the differences in angle information are relatively smaller when observed from multiple angles. With the increase in LAI in litchi orchards, the BRF on the principal plane would be saturated, but observation at hotspots could alleviate this phenomenon. The above analysis provides a reference for quantitative inversion of vegetation parameters using remote sensing monitoring information of typical perennial evergreen fruit trees.

Objectives: The geographical environment and military activities in the plateau area pose potential work-related stressors for military personnel, leading to burnout which is an external manifestation of internal energy exhaustion caused by stress. Without countermeasures, this can result in serious military problems. This study aims to examine the association between burnout and occupational stressors among military personnel stationed in the plateau area of China. Material and methods: A stratified randomized cluster sampling survey was conducted among 2026 military personnel from 6 different troops stationed in the plateau area of China. The Chinese Maslach Burnout Inventory-General Survey(MBI-GS in Chinese) was administered from March 2022 to December 2023, and data were analyzed using SPSS version 25. Results: A total of 2026 military personnel participated in the survey. The mean overall burnout score was 3.37 ± 0.73, with emotional exhaustion at 2.69 ± 0.89, depersonalization at 3.58 ± 0.92, and professional achievement at 3.81 ± 0.85 levels respectively reported by participants on average scale scores ranging from zero to six. Severe level of burnout was reported by 43.2% of participants while medium level of burnout was reported by 54.3%. Age, education level, length of military service, and household income were identified as important factors influencing burnout. Conclusion: This study highlights a relatively high prevalence of burnout among military personnel stationed in plateau areas necessitating attention towards their occupational health particularly focusing on working hours and economic aspects so as to formulate effective policies and implement intervention measures that strengthen career development for soldiers deployed in such regions.

Objective: To investigate the physical fitness level and health behavior status of preschool children in China, explore the relationship between physical fitness and health behavior, and further reveal the main factors affecting health behavior, to provide a reference for improving the physical fitness level of preschool children and maintaining healthy behavior. Methods: A total of 755 preschool children (394 boys and 361 girls, aged 4.52 ± 1.11 years) were selected from Chongqing and Liupanshui in China by cluster random sampling method for questionnaire survey and physical monitoring, and SPSS21.0 software was used to process and analyze the data. Results: (1) Heart rate (p = 0.015), protein content (p < 0.001), and time spent on the balance beam (p < 0.001) were significantly lower in boys than in girls, while BMI (p = 0.012), muscle mass (p < 0.001), and distance of standing long jump (p < 0.001) were significantly higher in boys than in girls. Meanwhile, systolic blood pressure (p = 0.004) and diastolic blood pressure (p = 0.001) of rural children were significantly higher than those of urban children, while BMI (p < 0.001) and sitting forward flexion (p = 0.019) were significantly lower than those of urban children. (2) The light-intensity physical activity (LPA) and moderate to vigorous physical activity (MVPA) of boys were significantly higher than that of girls (p < 0.001), and the MVPA of urban children was significantly higher than that of rural children (p = 0.001), and the former participated in sports classes more frequently (p < 0.001). (3) There was a significant correlation between physical activity (PA) and physical fitness indicators of preschoolers. Participating in sports interest classes was only significantly correlated with systolic blood pressure (r = 0.08) and sitting forward flexion (r = 0.09). (4) The PA level of preschool children was related to gender, household registration, kindergarten nature, age, residence environment, parental support, and participation degree. Participation in sports interest classes was related to gender, the nature of the kindergarten, household registration, age, and parent participation. Daily screen time was related to household registration, the nature of the kindergarten, the environment of residence, and the value perception of parents. Conclusions: There were different degrees of correlation between preschool children's physical fitness and health behaviors, and children's health behaviors were closely related to gender, environment, parents, and other factors. Therefore, how to increase the protective factors of children's health behaviors and controlling the risk factors may be crucial to promoting the development of good health behaviors and improving the physical fitness of preschool children.

Improving individuals' low-carbon awareness has become an important research topic. Gamification design is regarded as a potential IT solution to this social problem. Although much research is concerned with the effect of low-carbon awareness to improve individuals' behaviour, little attention has been paid to exploring how to improve low-carbon awareness, especially in the context of green gamification. To fill this research gap, our study uses the cognitive dissonance theory to build a theoretical model for exploring the impacts of green gamification factors on individuals' low-carbon awareness. The model is also used to explore the mediating role of cognitive dissonance and the moderating effect of emotional dependence. Empirical results reveal that visibility of achievement, competition, and interactivity have positive impacts on users' cognitive dissonance, which further positively affect users' low-carbon awareness. In addition, users' emotional dependence positively moderates the relationship between green gamification factors and users' cognitive dissonance. These results extend the cognitive dissonance theory and the literature on green gamification. New insights and practical implications for the designers of gamification application and environmental protection organisations are also provided in our study. [ABSTRACT FROM AUTHOR]

Purpose: Medication adherence in adults with H-type hypertension plays a crucial role in lowering blood pressure and treating complications. Cognitive function has been identified as a significant influencing factor for medication adherence, whereas excessive levels of homocysteine can impair cognitive function. Metamemory, which is influenced by cognitive function, also affects medication adherence. However, the complex relationship among these factors remains poorly understood among adults with H-type hypertension. Therefore, we hypothesize that metamemory serves as a mediator for the impact of cognitive function on medication adherence. Method: A total of 232 adults with H-type hypertension were enrolled to provide cognitive function scores, metamemory scores, and medication adherence rates. Results: A pairwise correlation exists among cognitive function, metamemory, and medication adherence. Metamemory partially mediates (57.5%) the relationship between cognitive function and medication adherence. Conclusion: Our findings suggest that interventions targeting improvements in metamemory may enhance medication adherence among individuals with H-type hypertension.

Purpose: This study analyzes the relationship between human papillomavirus (HPV) infection, vaginal microecology, and cervical lesions to provide a basis for the prevention and treatment of cervical cancer (CC) in the Xinjiang region. Methods: Real‐time quantitative PCR was used for HPV genotyping and viral load. The Gram staining and dry biochemical enzyme kit were utilized to diagnose vaginal secretions. The χ2 test and Logistic regression analysis were used for statistical analysis. Results: The HPV infection rate among women in the Xinjiang region was 30.29%, of which the single HPV infection accounts for 77%. HPV16 and HPV52 were the main infection types. There was significant differences in the HPV infection rate and infection types among the Han, Uighur, Hui, and Kazakh ethnic groups. The viral load of HPV16 and HPV52 increases with the upgrade of cervical lesions. There were significant differences in vaginal microecology evaluation indicators H2O2, SNA, LE, GUS, trichomonas, clue cells, and lactobacilli among different ethnic groups. HPV negative patients with varying grades of cervical lesions exhibit a notable variance in H2O2 and LE, which is statistically significant. Single HPV infection and high viral load HPV significantly increase the risk of CC. Conclusions: This study indicates that HPV infection and vaginal microecology differ among ethnic groups, which have a strong correlation with the progression of CC, offering guidance on CC screening and interventions in the Xinjiang area.

Background To assess the efficacy and safety of tucidinostat plus exemestane as a neoadjuvant strategy in early-stage breast cancer. Methods This prospective, open-label, single-arm phase II trial enrolled patients with stage II-III breast cancer with hormone receptor-positive and human epidermal growth factor receptor 2 (HER2)-negative. Eligible patients received tucidinostat plus exemestane, and then breast-conserving surgery (BCS) or modified radical mastectomy. Results Among 20 enrolled patients, 3 of them achieved preoperative endocrine prognostic index (PEPI) score of 0. Additionally, complete cell cycle arrest was observed in 7, radiologic objective response rate in 10, and disease control rate in 20 patients, pathological complete response in 1 patient, and 5 patients performed BCS. Ki67 suppression from baseline to surgery was observed in 17 of patients, with the Ki67 change ratio of −73.5%. Treatment-emergent adverse event included neutropenia, leukopenia, thrombocytopenia, lymphopenia, hypoalbuminemia, aspartate aminotransferase elevation, glutamyl transpeptidase elevation, anemia, and alanine aminotransferase elevation. Conclusions Despite the rate of PEPI score 0 was not high, tucidinostat plus exemestane as a neoadjuvant therapy might be well tolerated and showed promising clinical responses in patients with early hormone receptor-positive, HER2-negative breast cancer. To clarify the safety and efficacy of this strategy, further investigation is warranted. Clinical Trial Registration ChiCTR2100046678. [ABSTRACT FROM AUTHOR]

The world-class Jinding deposit in SW China has ~15 Mt of Zn and Pb metals combined, in an evaporite dome containing amounts of gypsum/anhydrite. These gypsum and anhydrite are mainly located in limestone breccias (Member I), gypsum-bearing complexes (Member III), and red mélange, with some occurring as veins in clast-free sandstone (Member IV) and as fractures/vugs of host rock. The gypsum/anhydrite and dome genesis remain equivocal. The gypsum in limestone breccias and in red mélange with flow texture contains numerous Late Triassic Sanhedong limestone fragments. The δ34S (14.1%–17%), δ18O (9.7%–14.6%), and 87Sr/86Sr ratios (0.706913–0.708711) of these gypsum are close to the S-O-Sr isotopes of the Upper Triassic Sanhedong Formation anhydrite in the Lanping Basin (δ34S = 15.2%–15.9%, δ18O = 10.9%–13.1%, 87Sr/86Sr = 0.707541–0.707967), and are inconsistent with the Paleocene Yunlong Formation gypsum in the Lanping Basin (87Sr/86Sr = 0.709406–0.709845), indicating that these gypsum were derived from the Upper Triassic Sanhedong Formation evaporite but not from the Paleocene Yunlong Formation, and formed as a result of evaporite diapirism. The δ34S (14.3%–14.5%), δ18O (10.1%–10.3%), and 87Sr/86Sr ratios (0.709503–0.709725) of gypsum as gypsum–sand mixtures in gypsum-bearing complexes are similar to the 87Sr/86Sr ratios of gypsum in the Yunlong Formation of the Lanping Basin and Cenozoic basins in the northern part of the Himalayan–Tibetan orogen, suggesting that the material source of this gypsum was derived from the Yunlong Formation, and formed as a result of gypsum–sand diapirism. The gypsum veins in clast-free pillow-shaped mineralized sandstone and the gypsum in host rock fractures and vugs formed after the supergene minerals such as smithsonite. The δ34S (−16.3%~−12.7%) and δ18O (−9.8%~−4.7%) of this gypsum indicate that the gypsum is of supergene origin with sulfate derived from the reoxidation of reduced sulfur. We confirmed that the Jinding dome is genetically related to diapir of the Late-Triassic Sanhedong Formation evaporite. Clast-free sandstone and gypsum-bearing complexes in the dome were produced by diapir of the Paleocene Yunlong Formation unconsolidated gypsum–sand mixtures. [ABSTRACT FROM AUTHOR]

Currently, data-driven deep learning models are widely applied in the field of wind power prediction. However, when historical data are insufficient, deep learning models struggle to exhibit satisfactory predictive performance. In order to overcome the issue of limited training data for new wind farms, this study proposes a novel transfer learning strategy to address the challenge of less-sample learning in short-term wind power prediction. The research is conducted in two stages. In the pre-training stage, the TimesNet-GRU prediction model is established using data from a source wind farm. Parallel TimesNet modules are employed to extract multi-period features from various input feature sequences, followed by the extraction of long- and short-term features from the time series through gate recurrent unit (GRU). In the transfer learning stage, an effective transfer strategy is designed to freeze and retrain certain parameters of the TimesNet-GRU, thereby constructing a prediction model for the target wind farm. To validate the effectiveness of this approach, the results from testing with actual data from five wind farms in northwest China demonstrate that the proposed method exhibits significant advantages over models without transfer learning as explored in this study.

Purpose: The high prevalence of multimorbidity in aging societies has posed tremendous challenges to the healthcare system. The aim of our study was to comprehensively assess the association of multimorbidity patterns and health-related quality of life (HRQOL) among rural Chinese older adults. Methods: This was a cross-sectional study. Data from 4,579 community-dwelling older adults aged 60 years and above was collected by the clinical examination and questionnaire survey. Information on 10 chronic conditions was collected and the 3-Level EQ-5D (EQ-5D-3L) was adopted to measure the HRQOL of older adults. An exploratory factor analysis was performed to determine multimorbidity patterns. Regression models were fitted to explore the associations of multimorbidity patterns with specific health dimensions and overall HRQOL. Results: A total of 2,503 (54.7%) participants suffered from multimorbidity, and they reported lower HRQOL compared to those without multimorbidity. Three kinds of multimorbidity patterns were identified including cardiovascular-metabolic diseases, psycho-cognitive diseases and organic diseases. The associations between psycho-cognitive diseases/organic diseases and overall HRQOL assessed by EQ-5D-3L index score were found to be significant (β = − 0.097, 95% CI − 0.110, − 0.084; β = − 0.030, 95% CI − 0.038, − 0.021, respectively), and psycho-cognitive diseases affected more health dimensions. The impact of cardiovascular-metabolic diseases on HRQOL was largely non-significant. Conclusion: Multimorbidity was negatively associated with HRQOL among older adults from rural China. The presence of the psycho-cognitive diseases pattern or the organic diseases pattern contributed to worse HRQOL. The remarkable negative impact of psycho-cognitive diseases on HRQOL necessiates more attention and relevant medical assistance to older rural adults. [ABSTRACT FROM AUTHOR]

Antibiotic resistance genes (ARGs) are widespread in aquaculture and pose a huge threat to aquaculture organisms and human health. In this study, occurrences and relative abundances of ARGs were analysed in the guts of products cultured in freshwater ponds in the Yangtze River Delta region in China. A total of 29 ARGs were found in the gut samples, with detection frequencies ranging from 4.8% to 81%, and the relative abundances (ARGs/16S rRNA) ranging from 10−7 to 1. In addition, the human dietary intake of ARGs via aquaculture products was assessed, where the daily intake of most ARGs via aquaculture products was higher than those via PM2.5 and drinking water, but lower than that via vegetables. The relative abundances of MGE (IS613, Tp614, tnpA and int1) were significantly correlated with those of multiple ARGs, indicating the horizontal gene transfer (HGT) of ARGs among gut microorganisms. Proteobacteria, Firmicutes and Actinobacteria were the dominated microbial communities found in the guts of aquaculture products. In addition, significant correlations were found between Cyanobacteria and int1, between Nitrospira and tetE, and between sul2 and aadA2, indicating potential same hosts of these genes. In addition, results from co-correlation indicated both HGT (dominated by MGEs) of ARGs and the enrichment of ARGs in bacteria. MGEs, mostly int1, were more effective than bacteria in increasing the ARG abundance. This study could provide a better understanding of the transmission of ARGs in the aquaculture environment and improve the quality of aquaculture products and the ecology. [ABSTRACT FROM AUTHOR]

Infant's gender may have influences on composition of breastmilk. This study investigated differences in whey fractions from milk of mothers (n = 12, 3 biological repeats) with male or female babies using a 4D label‐free proteomics. Altogether, 1572 proteins were identified and 42 of them were differentially expressed. Majority of the different proteins are located in extracellular position and possessed domain of immunoglobulin V‐set. The screened proteins were observed to contribute greatly to functions of cellular process, binding, and cell part; and pathways of immune system and immune disease. The findings may afford beneficial knowledge for understanding differences in breastmilk composition. [ABSTRACT FROM AUTHOR]

This paper qualitatively and quantitatively examines the development of the sovereign debt market in Prewar China under different governments. During the Beijing Era (1912–26), accompanied by the establishment of necessary financial institutions, the sovereign debt market emerged to meet fiscal needs. Surprisingly, the Nationalist government, in power from 1927, successfully cultivated a robust market characterized by its expanding size and liquidity. Setting itself apart from its predecessors, the government established credibility as a borrower in two key ways. Firstly, it demonstrated unwavering commitment to debt service by settling previous debts and offering well‐structured new ones, even during challenging times. Furthermore, the government escrowed fiscal revenue, pledged for debt repayments, to a semi‐independent committee of private bankers on behalf of debtholders, enhancing public confidence. Secondly, the government showcased its ability to secure tax revenues for debt repayments. However, starting from 1931/2, the debt market experienced a decline due to the government's compromised ability to pay resulting from external wars and shifting political priorities that weakened its commitment to debt repayments. Empirical evidence confirms the market's responsiveness to regime shifts and policy changes. This paper sheds light on how a nascent autocratic government can successfully borrow from the public.

This study examined how shyness-sensitivity and unsociability were associated with social, school, and psychological adjustment in Chinese children and adolescents. Participants included 564 children (272 boys, M[subscript age] = 9 years) and 462 adolescents (246 boys, M[subscript age] = 13 years) in a suburban region in China. Data were obtained from peer assessments, sociometric nominations, teacher-ratings, self-reports, and school records. The results showed that relations of shyness and unsociability with adjustment differed in middle childhood and early adolescence. Shyness tended to be associated with social and psychological problems more evidently in adolescence than in childhood. In contrast, unsociability was associated with problems more evidently across domains in childhood than in adolescence. The results indicate that the implications of the two main forms of social withdrawal may vary across developmental periods.

This study investigated the role of resilience as a mediator and the place of residence as a moderator of parenting stress and parental burnout. The Parenting Stress Index-Short Form, Parental Burnout Assessment, and Connor-Davidson Resilience Scale were administered to 249 Chinese parents of children with ASD (M = 33.95 years, SD = 7.6). Results show that resilience partially mediates the relation between parenting stress and parental burnout. Besides, both the effect of parenting stress on parental burnout and the mediating effect of resilience are moderated by rural/urban residence. This study highlights parenting stress is a risk factor for parental burnout and resilience is the potential mechanism underlying this relation. These findings provide implications for family services for parents of children with ASD. [ABSTRACT FROM AUTHOR]

Against the background of the accelerated evolution of the new round of scientific and technological revolution and industrial change, scientific and technical talents, as essential innovation resources, play an important role in promoting the high-quality development of the manufacturing industry. Based on the panel data of 30 provinces in China from 2012 to 2021, the article constructs a fixed-effects model and systematically researches the impact of scientific and technological talents on the high-quality development of the manufacturing industry. The results show that scientific and technical talents play a significant role in promoting the high-quality development of the manufacturing industry, and the upgrading of the consumption structure and the accumulation of productive service industries play a mediating role. Heterogeneity analysis found that the promotion effect of scientific and technical talents is more favorable in the eastern region, medium-technology level manufacturing, and labor-intensive manufacturing. Among the three sub-dimensions of scientific and technological talents, the scale of scientific and technical talents has the most significant impact on the development of the manufacturing industry. The analysis of the spatial spillover effect finds that scientific and technological talents will have a positive spillover effect on the development of the manufacturing industry in neighboring areas. The study provides a basis for relevant departments to formulate effective strategies and policies. [ABSTRACT FROM AUTHOR]

Objective: Listeriosis is caused by the bacterium, Listeria monocytogenes, and is a significant health concern because of high hospitalization and mortality rates. This study reports seven cases of pregnancy‐associated listeriosis diagnosed with matrix‐assisted laser desorption ionization‐time of flight (MALDI‐TOF) mass spectrometry performed on infection‐positive blood culture. Methods: Blood culture‐positive samples of seven patients whose pregnancy was complicated by Listeria infection and treated at Xuanwu Hospital of Capital Medical University between January 2016 and December 2021 were analyzed retrospectively. Strains identified by MALDI‐TOF mass spectrometry were compared with colony identification results. Identification accuracy and consistency were assessed. Results: A total of seven strains of Listeria were collected from seven pregnant women presented with fever (37.6–39.9°C). Clinical abnormalities included abnormal liver function, emaciation, hypoalbuminemia, hypocalcemia, hypokalemia, hyponatremia, ketosis, mild to moderate anemia, leukopenia, and thrombocytopenia. Compared with the traditional culture method, MALDI‐TOF mass spectrometry led to much earlier identification (4–6 h vs. 3–4 days) with 100% identification accuracy. Of the seven pregnancies complicated by Listeria, only two led to live births. Of the five fetal deaths, three occurred in the second trimester. Conclusion: In this series of pregnancy‐associated listeriosis cases, the fetal mortality rate was 71%. MALDI‐TOF mass spectrometry is a valuable method that can identify Listeria from blood culture rapidly and accurately. [ABSTRACT FROM AUTHOR]

To alleviate the contradiction between the shortage of freshwater resources and the rapid development of industries and agriculture in China, field experiments were conducted to study the response of tomatoes to different water salinity (ECi) levels under drip irrigation in coastal semi-humid areas and arid areas. The effects of water salinity on salt accumulation in the root zone, tomato growth, yield, yield components, and quality response were investigated. The results indicated that the electrical conductivity of the soil saturation extract (ECe) increased with the irrigation water salinity. In semi-humid area, the maximum ECe was not higher than 5 dS/m, and the value was lower in wet year, at approximately 2 dS/m. In arid area, the ECe increased in the first year and then tended to balance. The ECe exceeded 4 dS/m when the ECi is higher than 6.6 dS/m. Salinity hindered the yield of tomatoes, which was mainly manifested by a reduced fruit diameter, fruit number, and single fruit weight. The salinity thresholds that tomato can endure without yield reduction 1.8 dS/m in semi-humid area and 2.1 dS/m in arid area, when ECe of root zone exceeded the threshold, for every 1 dS/m increase in ECe, the relative yield decreased by 14% and 12%, respectively. Nevertheless, tomato fruit quality is improved under saline water irrigation. Vitamin C (VC) content shows a significant quadratic curve relationship with ECe, and the maximum appeared at 4.0 dS/m in semi-humid area and 5.9 dS/m in arid area. Total sugar (TS) and total acid (TA) contents were significantly improved in arid area, for every 1 dS/m increase in ECe, the relative TS and TA increased by 12.8% and 20.3%, respectively. From the comprehensive point of saving water, avoiding yield reduction, and improving tomato fruit quality, saline water of about 6.3 dS/m and 4.9 dS/m is suggested for drip irrigation of tomatoes in semi-humid areas and arid areas in China.

The goal of this longitudinal study was to examine developmental trajectories of emotional school engagement among Chinese elementary school children. In addition, we sought to explore the role of early peer relationships and academic achievement as predictors of these trajectories. Participants at the outset of the study were N = 1,136 second-grade students (582 boys; Mage = 8.59 years) in mainland China. At Time 1, peers provided nominations of peer preference and victimization, and teachers rated children's academic achievement. Longitudinal data on self-reported emotional engagement were then collected annually for four years. Among the results, two distinct trajectories of emotional school engagement were identified: High-Decreasing and Low-Increasing. Children at Time 1 with more positive peer relationships and higher academic achievement were more likely to be in the High-Decreasing trajectory. Children with higher academic achievement also displayed a more rapid decrease in their emotional engagement in the High-Decreasing subgroup and a lower increase in their emotional engagement in the Low-Increasing subgroup. Results are discussed in terms of the implications of emotional engagement in the Chinese cultural context. [ABSTRACT FROM AUTHOR]

Purpose: We conducted a multicenter cross-sectional study in central and western China to explore the association between inflammatory diet and stomach cancer odds. Patients and Methods: Participants from five hospitals in the central and western regions were collected. All participants completed the questionnaire we provided before the gastroscopy examination, which includes inquiries about risk factors for stomach cancer and food frequency. All participants underwent gastroscopy, and a mucosal biopsy was confirmed pathologically. Pathological findings were classified as chronic gastritis group, precancerous lesions group and stomach cancer group. Dietary Inflammatory Index (DII) scores were calculated based on the frequency of food occurrences in the questionnaire, and finally SPSS was used to calculate the correlation between variables. Results: A total of 1162 patients were included in this study, including 668 cases of chronic gastritis, 411 cases of precancerous lesions, and 83 cases of cancer. A single factor analysis was conducted to examine the risk factors of stomach cancer, revealing a significant association between a pro-inflammatory diet and the stomach cancer odds (p value < 0.05). The results of binary classification analysis further confirmed that a pro-inflammatory diet is a risk factor for stomach cancer 【odds ratio (OR) =7.400)】. Moreover, correlation analysis demonstrated a positive correlation between the severity of gastric mucosal diseases and an inflammatory diet (including anti-inflammatory and pro-inflammatory diets) (rs=0.274, p-value < 0.001). Conclusion: Pro-Inflammatory diet is a risk factor for stomach cancer, and may accelerate the progression of stomach mucosal disease. [ABSTRACT FROM AUTHOR]

Creativity encompasses both novelty and usefulness, with novelty referring to the generation of unique and uncommon ideas, while usefulness pertains to the effectiveness and appropriateness of these ideas in addressing the given task. The comprehension of the process of coordinated development for children's novelty and usefulness, including the potential gender differences, is crucial; however, it still lacks clarity in the current academic discourse. To address these gaps, this study investigated the joint developmental trajectories of novelty and usefulness as well as the gender differences in trajectory group membership among Chinese children. A sample of primary school children (initial grade 3, N = 665; 46.4% girls; initial Mage = 8.60 years) were followed for three years. The results revealed a negative association between novelty and usefulness across all three time points. Through parallel-process latent class growth modeling, three distinct trajectories of novelty and usefulness were identified: the High Novelty Decline–Medium Usefulness Increase–Stability Group (66%), the Low Novelty Increase–High Usefulness Decline–Convergence Group (19%), and the Low Novelty Decline–High Usefulness Increase–Divergence Group (15%). These findings suggest that the development of children's creativity is influenced by a multifaceted pattern involving both novelty and usefulness. Moreover, gender differences in trajectory group membership were examined and discussed within the context of creativity development in Chinese children. [ABSTRACT FROM AUTHOR]

Background: Infectious diseases are a serious threat to human especially since the COVID-19 outbreak has proved the importance and urgency of their diagnosis and treatment again. Metagenomic next-generation sequencing (mNGS) has been widely used and recognized in clinical and carried out localized testing in hospitals. Increasing the training of mNGS detection technicians can enhance their professional quality and more effectively realize the application value of the hospital platform. Methods: Based on the initial theoretical understanding and practice of the mNGS platform for localization construction, we have designed a training program to enhance the ability of technicians to detect pathogens by utilizing mNGS, and hence to conduct training practices nationwide. Results: Until August 30, 2022, the page views of online classes have reached 51,500 times and 6 of offline small-scale training courses have been conducted. A total of 67 trainees from 67 hospitals have participated in the training with a qualified rate of 100%. After the training course, the localization platform of 1 participating hospital has been put into use, 2 have added the mNGS localization platform for admission, among which 3 have expressed strong intention of localization. Conclusions: This study focuses on the training procedures and practical experience of the project which is the first systematic standardized program of mNGS in the world. It solves the training difficulties in the current industry, and effectively promotes the localization construction and application of mNGS in hospitals. It has great development potential in the future and is worth further promotion. [ABSTRACT FROM AUTHOR]

In wind power prediction, the input probability distributions in the different sub-periods are shifted owing to the strong randomness of the input features, such as wind speed and direction. This may violate the assumption for machine learning that the training and test data meet the condition of being independent and identically distributed, resulting in an insufficient generalization ability of the prediction model that is trained with the training data and applied to unknown test data. To address this problem, this study proposes an adaptive temporal transformer method for short-term wind power forecasting. First, a temporal transformer model with a gate recurrent unit and multi-head attention layers was used to extract the short- and long-term temporal information of the multiple input variables. Then, an adaptive learning strategy consisting of two stages—temporal distribution characterization and temporal distribution matching—was developed to explore the common knowledge hidden in each sub-period. The case results for an actual wind farm in northwest China showed that the proposed method could effectively weaken the adverse effects of the shifts in time series distribution on forecasting and improve the accuracy and generalization of short-term wind power prediction.

The aims of the present study were to (a) examine the factor structure of the "Self-Report Coping Scale" in a sample of Chinese early adolescents and (b) explore associations between coping and socioemotional functioning in this sample. Participants were N = 569 elementary school students (307 boys) in Grades 4 to 6. Participants completed a measure of coping in response to an argument with a friend. Students' functioning across multiple domains was assessed using self, peer, and teacher reports. Results suggested a five-factor model of coping in Chinese early adolescents (problem solving, seeking social support, internalizing, externalizing, distancing). In support of predictions, internalizing and distancing coping were positively related to adjustment indices, whereas seeking social support and problem-solving coping were negatively related to outcomes. Results are discussed in terms of the important role of coping for adolescents' adjustment across multiple domains and in relation to recent shifts in traditional Chinese cultural values.

The paper attempts to explore the activating strategies to fossilizations for Chinese EFL learners. Fossilization, although always being ignored in China, still exerts its important role in blocking the EFL learning process for Chinese learners. To overcome this learning barrier, this paper is written to put forward the practical solutions to fossilization.

This study explored the extent to which loneliness of Indonesian and Chinese adolescents was predicted by their intimacy and conflict with friends and parents. The total sample included 1,833 thirteen- and fifteen-year-old adolescents recruited from urban schools. Boys reported more loneliness than girls, and Chinese boys reported more loneliness than Indonesian boys. Indonesian adolescents reported less intimacy with friends, more intimacy with parents, and more conflict with peers and parents than did Chinese adolescents. Consistent with expectations, loneliness was predicted primarily by low intimacy with friends for Chinese adolescents and by low social preference for Indonesian adolescents. Whereas low intimacy and conflict with parents predicted loneliness for adolescents in both countries, these effects were stronger for Chinese than Indonesian adolescents. These findings suggest that experiences of loneliness across cultures vary as a function of the relative salience of qualities of peer and parent relationships.

Background: Our previous study reported a high rate of recurrence in children with Clostridioides difficile (C. difficile) infection (CDI) after conventional antibiotic therapy. Here, we aimed to explore whether metronidazole and vancomycin resistant C. difficile isolates are circulating in pediatric CDI.Methods: Antimicrobial susceptibility testing (AST) using the agar dilution method according to the Clinical and Laboratory Standard Institute (CLSI) were performed on C. difficile isolates collected from children with CDI between 2019 and 2022 at the Shanghai Children's Hospital. Whole-genome sequencing (WGS) was performed on all C. difficile isolates, and the presence of antibiotic resistance genes (ARGs) were identified using Resfinder and the Comprehensive Antibiotic Resistance Database (CARD). The presence of plasmid pCD-METRO was detected using SRST2 (v0.2.0) against 8 pCD-METRO coding sequences.Results: A total of 50 C. difficile isolates were collected from stools of CDI children. The overall resistance rate on all isolates was 30.00% for metronidazole, 6.00% for vancomycin, 0% for rifaximin, 2.00% for rifampin, 24.00% for meropenem, 100.00% for ceftriaxone and clindamycin, 86.00% for erythromycin, 30.0% for levofloxacin, and 50.0% for tetracycline. Multidrug-resistant (MDR) was presented in 44 isolates (88.00%). Sixteen reported potential ARGs relating with resistance to antibiotic classes of aminoglycoside (AAC(6')-Ie-APH(2")-Ia, aad(6), ANT(6)-Ib, APH(2")-If, APH(3')-IIIa), lincosamide-clindamycin-erythromycin (ErmB, ErmQ), fluoroquinolones (CdeA), glycopeptides (vanRG), nucleoside (SAT-4), tetracycline (tetM, tetA(P), tetB(P), tetO), and trimethoprim (dfrF) were identified. However, the pCD-METRO plasmid and vanA/B were not detected in any isolates.Conclusion:C. difficile isolates from children with reduced susceptibility to metronidazole and vancomycin are emerging in pediatric CDI in China. The lack of pCD-METRO plasmid and vanA/B associated with reduced antibiotic susceptibility suggests there are additional mechanisms of resistance. [ABSTRACT FROM AUTHOR]

South China is dominated by mountainous agriculture and croplands that are at risk of flood disasters, posing a great threat to food security. Synthetic aperture radar (SAR) has the advantage of being all-weather, with the ability to penetrate clouds and monitor cropland inundation information. However, SAR data may be interfered with by noise, i.e., radar shadows and permanent water bodies. Existing cropland data derived from open-access landcover data are not accurate enough to mask out these noises mainly due to insufficient spatial resolution. This study proposed a method that extracted cropland inundation with a high spatial resolution cropland mask. First, the Proportional–Integral–Derivative Network (PIDNet) was applied to the sub-meter-level imagery to identify cropland areas. Then, Sentinel-1 dual-polarized water index (SDWI) and change detection (CD) were used to identify flood area from open water bodies. A case study was conducted in Fujian province, China, which endured several heavy rainfalls in summer 2022. The result of the Intersection over Union (IoU) of the extracted cropland data reached 89.38%, and the F1-score of cropland inundation achieved 82.35%. The proposed method provides support for agricultural disaster assessment and disaster emergency monitoring. [ABSTRACT FROM AUTHOR]

Measuring the distribution of the fishing effort of trawlers is of great significance for describing marine fishery activities, quantifying fishing systems in terms of marine ecological pressure, and revising the regulations of fishing. The purpose of this paper is to develop an efficient learning algorithm to detect the fishing behavior of trawlers to analyze the distribution of fishing effort. The vessel-monitoring system data of more than 4600 trawlers from September 2019 to April 2023 were used for feature extraction. According to the spatiotemporal information provided by the vessel position data, 11-dimensional features were extracted to form the feature vectors. A Slime Mould Algorithm-optimized Light Gradient-Boosting Machine (SMA-LightGBM) algorithm was proposed to classify the feature vectors to recognize fishing behavior. The presented method showed a remarkable generalization ability and high accuracy, sensitivity, specificity, and Matthews correlation coefficient in the test results, with scores of 98.23%, 98.75%, 97.75%, and 0.9646, respectively. Subsequently, the trained model was used to identify the fishing behavior of trawlers belonging to the coastal provinces of the Bohai Sea and the Yellow Sea in the sea area of 117 °   E ~ 132 °   E , 26 °   N ~ 41 °   N . The fishing effort was calculated and evaluated according to the fishing behavior recognition results. The mean absolute error was 0.3031 kW·h, and the coefficient of determination score was 0.9772. The thermal map of the fishing effort of the trawler was mapped, and the spatiotemporal characteristics were estimated in the region of interest from 2019 to 2023 with a spatial resolution of 1 8 degree × 1 8 degree. This method is an efficient way of analyzing the spatiotemporal characteristics of the fishing effort of trawlers. It provides a quantitative basis for the assessment of fishery resources and can inform fishing policies. [ABSTRACT FROM AUTHOR]

Coalbed hydrogen sulfide (H2S) is a toxic and corrosive gas, it's very important for researching the origin of H2S in coalbed and related metabolic characteristics of microbes in the bioconversion of coal. The purpose of this study is to clarify the contribution and influencing factors of bacterial and sulfate-reducing bacterial (SRB) communities in the Taiyuan Formation (Nos. 5 and 11 coal seams) of the Hancheng mining area, by using gas composition testing, water quality measurements, 16S rRNA amplicon sequencing, and fluorescence real-time quantitative (qPCR) analysis. The results indicate that the coal seam gas is mainly composed of methane with a trace amount of H2S ranging from 4 to 56 ppm. The H2S content exhibits a positive correlation with the SRB gene copy number within the range of ∼30 to 200 copies/mL, indicating a strong association between the production of H2S and the contribution of SRB in the study area. The presence of Desulfobulbus, Desulfovibrio, Desulfomicrobium, Desulfotomaculum, Desulfobacca, Thermosinus, Desulfococcus, Desulfarculus, and Syntrophobacter genus from the coalbed-produced water further proves that H2S is reduced in dissimilatory sulfate reduction (DSR) pathway. Bacteria and SRB play a critical role in the conversion of coal organic matter through biodegradation. SRB community composition is more related to total organic carbon, total dissolved solids, SO 4 2- and trace elements. This study gives an in-depth explanation of the formation of H2S in coalbed and provides novel views in toxic gas removal in future gas exploitation. The community composition of in-situ bacteria and sulfate-reducing bacteria in the coal seam is characterized. The genesis and control factors of hydrogen sulfide in coal seams are discussed. The possible pathways during hydrogen sulfide formation are analyzed. [ABSTRACT FROM AUTHOR]

Aims. We aimed to investigate nursing students' spiritual care competence, perceived professional benefit, and retention intention and to analyze the relationship among these variables. Background. Nurse shortages are a global issue, and intern nursing students' willingness to remain in the nursing profession is important. Spiritual care can reduce patients' depression and improve their quality of life. Implementing spiritual care can help individuals have satisfying experiences. Perceived professional benefit is a positive emotional experience that is important in retention intention. However, the relationship among spiritual care competence, perceived professional benefit, and retention intention remains unclear. Methods. In this cross-sectional and correlational study, convenience sampling was used to recruit 266 intern nursing students in 10 hospitals throughout China. An online questionnaire was used to assess their sociodemographic characteristics, spiritual care competence, perceived professional benefit, and retention intention. Statistical analyses included the t-test, analysis of variance, Pearson's correlation analysis, and bootstrap analysis. Results. Intern nursing students' mean scores were 103.35 ± 19.00 for spiritual care competence, 72.88 ± 10.40 for perceived professional benefit, and 19.58 ± 3.37 for retention intention. Spiritual care competence was positively correlated with perceived professional benefit (r = 0.545; p < 0.01) and retention intention (r = 0.149; p < 0.05). Perceived professional benefit was also positively correlated with retention intention (r = 0.320; p < 0.01). Bootstrap analysis showed that perceived professional benefit completely mediates the relationship between spiritual care competence and retention intention. Conclusions. We found that nursing interns had a moderate level of retention intention, and perceived professional benefit was the mediating variable between spiritual care competence and retention intention. Implications. Our study results suggest that nursing administrators and educators should improve nursing interns' spiritual care competence and perceived professional benefit to enhance their willingness to remain in the nursing profession and alleviate nurse shortages.

Analyzing the impact of changes in corporate income tax policy on firm exports provides a critical assessment of the effectiveness of tax policies in stimulating export growth. It offers insights into the influence of tax policies on intra-firm resource allocation efficiency. However, there is limited attention in the literature devoted to examining firms' export responses to these tax policy shifts, often overlooking the underlying mechanisms. This study investigates the causal relationship between reduction in corporate income tax rate and adjustment in export structure, employing a difference-in-differences approach and drawing on data from Chinese manufacturing firms between 2000 and 2013. Our findings indicate that China's corporate income tax reform in 2008 heightened the concentration of firms' export products by enhancing labor productivity and facilitating the accumulation of fixed assets. Additionally, this tax reduction expanded the range of exported products and increased the proportion of firms' core and high-technological products. [ABSTRACT FROM AUTHOR]

College freshmen are special populations facing great challenges in adapting to the brand new environment, and their lifestyle and emotional states are worthy of attention. Especially during the COVID-19 pandemic, their screen time and prevalence of negative emotions were significantly increased, but few studies have focused on such situation of college freshmen and illustrated relevant mechanisms. Thus, based on a sample of Chinese college freshmen during the COVID-19 pandemic, the current study aimed to investigate the association between their screen time and negative emotions (depression, anxiety and stress), and further explore the mediating effects of sleep quality. Data from 2,014 college freshmen was analyzed. The screen time was self-reported by participants using predesigned questionnaires. The Pittsburgh Sleep Quality Index (PSQI) and Chinese Version of Depression Anxiety and Stress Scale-21 (DASS-21) were used to assess sleep quality and emotional states, respectively. The mediation analysis was conducted to examine the meditation effect. Results indicated that participants with negative emotions tended to have longer daily screen time and worse sleep quality, sleep quality partially mediated the association between screen time and negative emotions.The critical role of sleep quality and related intervention measures should be recognized and implemented.

Introduction:The coronavirus disease 2019 (COVID-19) pandemic has created lots of difficulties for individuals to seek medical help offline. Telehealth is considered as a potential approach to solve this issue. During the COVID-19 pandemic, although the use of telehealth has increased in the short term, it still remains unknown whether the use of telehealth can maintain a high level of development in the long term. The purpose of this article is to investigate the impact of COVID-19 pandemic on telehealth use across time and regional medical resources. Materials and Methods:Our research used the Internet search index from Baidu Index Platform in 31 provinces of China as the proxy of telehealth use. A total of 2,119,486 times of searching behaviors from January 2018 to December 2021 are included in our dataset. Changing plots, the method of analysis of variance and empirical models are applied to reveal the relationship between COVID-19 pandemic and telehealth use. Results:Baidu Index counts increased (p < 0.01) at the beginning of COVID-19 pandemic (2020) but started to decline (p < 0.01) during the period of regular epidemic prevention and control (2021). Moreover, the counts of Baidu Index in regions with rich medical resources are higher than those in other regions in 2020. Comparing Baidu Index counts in 2020, the COVID-19 pandemic has higher positive effects on telehealth use during the period of 2021 in regions with average and poor medical resources. Conclusions:COVID-19 pandemic has a positive effect on telehealth use in 2020 but has a negative effect in 2021. During the epidemic, telehealth use differs in regions with rich, average, and poor medical resources. Our findings indicate that the use of telehealth should be promoted with different measures in regions with different medical resources, thereby contributing its healthy development in the long term.

Background: Total hip arthroplasty (THA) performed using the direct anterior approach (DAA) has demonstrated favourable early-, mid-, and long-term outcomes. However, the traditional femoral release technique remains technically demanding and is associated with challenges and a heightened risk of complications. This study aimed to compare the clinical outcomes of patients who underwent THA with DAA performed using either the femoral-release-first (FRF) or the traditional approach (TA) strategy. Methods: A retrospective analysis of demographics, clinical and radiological outcomes, and occurrence of complications was performed using data from 106 patients between 2018 and 2019. The patients were categorised into two groups: FRF (44 hips) and TA (69 hips). Results: The FRF group showed a reduced operative time, haemoglobin (Hb) drop, postoperative hospital stay, and more optimal acetabular cup anteversion angles. Furthermore, during the first 2 months postoperatively, the FRF group demonstrated superior visual analogue scale, Harris Hip, and Oxford Hip scores. In the TA group, two hips experienced greater trochanter fractures, and one experienced delayed incision healing. Conclusions: Compared with the TA, employing the FRF strategy during THA with DAA resulted in improved outcomes within the first 2 months postoperatively and comparable functional recovery beyond this period. The FRF method exhibited advantages such as favourable acetabular exposure and alignment and a reduced risk of complications. Therefore, the FRF strategy may be a favourable option.
