The Impact of Stigma on Self-Management Behavior Among People with HIV in China: The Role of Social Support and Self-Esteem.

Understanding the psychosocial factors influencing self-management behaviors among people with HIV (PWH) is crucial for effective medical interventions and improving their quality of life. However, there has been limited research exploring the psychosocial mechanisms influencing self-management behaviors among PWH in China. Our study examined the relationship between stigma, social support, self-esteem, and self-management behaviors among PWH, as well as whether social support and self-esteem mediate these relationships. Cross-sectional data were collected from 282 PWH in Sichuan Province, China. Data were collected using four validated self-report measures (HIV Stigma Scale, HIV/AIDS Patient Self-Management Scale, Social Support Rating Scale, and Self-Esteem Scale). Structural equation modeling was used to examine the different pathways influencing self-management behaviors. All the impacts on self-management behavior outcomes were found to be significant. The final mediation model indicated that social support and self-esteem significantly mediated the relationship between stigma and self-management behaviors. These findings underscore the importance of addressing stigma and enhancing social support and self-esteem in interventions aimed at promoting self-management behaviors among PWH.

Frost Resistance Differences of Concrete in Frequent Natural Freeze–Thaw versus Standard Rapid Method

In order to find the anti-freezing durability differences between concrete in the frequent natural freeze–thaw conditions in the northwest of Sichuan Province, China, and concrete in the rapid freeze–thaw conditions of the standard rapid method, the typical temperature and humidity of the northwest of Sichuan Province were simulated. The results showed that the average number of freeze–thaw cycles in the northwest of this province can reach up to 150 per year. The relative dynamic modulus of C30 ordinary concrete, which is 100% pre-saturated, still remained above 90% after 450 cycles in simulated environments. However, during the rapid freeze–thaw test, even the C30 air-entrained concrete failed after 425 cycles. Compared to the saturation degree of concrete itself, the continuous replenishment of external moisture during freeze–thaw cycles is a key factor affecting the frost resistance of concrete. Rapid freeze–thaw reduces the number of the most probable pore sizes in ordinary concrete, and the pore size distribution curve tends to flatten. The reduction rate of the surface porosity of air-entrained concrete before and after rapid freeze–thaw is only about one third of that of ordinary concrete.

Research and analysis on the situation of diagnosis and treatment capabilities of breast cancer in China county.

8 Background: 1. In 2016, 306,000 breast cancer cases were newly diagnosed in China, with one-third in rural areas. Breast cancer ranked second in incidence (22.47/105) among female cancers in Sichuan Province. 2. Health resources are unequally distributed in China, especially in Sichuan Province where 43.27% reside rurally. County hospitals play a vital role in rural patients' diagnosis, treatment, and referrals. Methods: This cross-sectional observational study surveyed 124 county-level hospitals that had treated breast cancer in 183 counties in Sichuan Province from December 2023 to January 2024. Outcomes include: 1) hospital level; 2) oncology certification; 3) availability of dedicated breast department and staffing; 4) breast cancer diagnosis and treatment technology; 5) pre-treatment TNM staging rate; 6) anti-neoplastic drugs and support Accessibility of medicines. Results: Out of 124 hospitals surveyed, 6 excluded for zero breast cancer cases in 2023. The remaining 118 hospitals revealed: 1) 78.81% tertiary, 93.22% public; 2) 75.42% with special outpatient qualifications, 57.63% with concurrent special antineoplastic drug designations, 17.80% with one qualification; 3) 57.63% with dedicated breast units, but only 16.1% with specialized breast cancer staff; 4) 31.36% with full breast imaging modalities, 78.23% lacking mammography; PET-CT and bone scan availability: 5.93% and 9.32%; 5) 71.19% with independent pathology, but only 30.65% providing comprehensive services; 6) Surgeries for breast cancer: 86.44% (44.07% breast conservation), radiation therapy availability: 39.83%; 7) AJCC TNM staging rate: 77.12%; 8) Antineoplastic accessibility: conventional chemotherapy (93.22%), anti-HER2 therapy (28.81%), endocrine therapy (47.46%), CDK4/6 inhibitors (26.27%, with 41.53% having only one); 9) Analgesics: 87.90% (morphine 94.92%, tramadol 88.98%, fentanyl patches 34.75%, oxycodone 46.61%); antiemetics (5-HT3 antagonists 69.49%, NK1 antagonists 72.88%, olanzapine 48.31%, metoclopramide 64.41%); medications for hematologic toxicity: 51.61%. Conclusions: Shortages exist in specialized breast care units and trained personnel among county hospitals in Sichuan, China. Special outpatient qualifications and antineoplastic prescription credentials concentrated mainly at tertiary centers. Enhancing imaging and histopathology capacities for breast cancer diagnosis is an urgent need. While conventional chemotherapies demonstrate good accessibility, anti-HER2 targeted therapies, endocrine therapies, and CDK4/6 inhibitors covered by national insurance have limited availability. Enhanced provision of new antiemetics and analgesics is needed. [Table: see text]

The work stress, occupational burnout, coping strategies and organizational support of elite sports coaches in Sichuan Province: the mediating role of organizational support.

This study investigated the relationships between job pressure, occupational burnout, organizational support and coping strategies among competitive sports coaches in Sichuan Province, China. It also assesses the impact of job pressure on occupational burnout and the mediating roles of organizational support and coping strategies. A survey was conducted with 207 competitive sports coaches from Sichuan Province, China. Basic information and data on job pressure, occupational burnout, organizational support and coping strategies were collected. Correlations between variables were analyzed, and a theoretical model for hypothesizing the mediating effects was established. A multiple regression model was used to predict the relationships between occupational burnout and job pressure, organizational support and coping strategies. (1) Job pressure was significantly positively correlated with occupational burnout (R = 0.436, p < 0.001) and negative coping (R = 0.389, p < 0.001) but significantly negatively correlated with organizational support (R = -0.503, p < 0.001). Occupational burnout was significantly negatively correlated with academic title (R = -0.158, p = 0.023) and organizational support (R = -0.349, p < 0.001) but significantly positively correlated with negative coping (R = 0.440, p < 0.001). Organisational support was significantly positively correlated with positive coping (R = 0.222, p = 0.001) but significantly negatively correlated with negative coping (R = -0.207, p = 0.003). (2) Mediating effects: Job pressure indirectly affects occupational burnout via organizational support and negative coping strategies. (3) Multiple regression: Y1 (Job Pressure) = 69.262 + 1.172 × Emotional Exhaustion -2.231 × Emotional Support +1.041 × Negative Coping -6.554 × Academic Title (from high to low). Y2 (Occupational Burnout) = 25.609 + 0.141 × Job Pressure - 0.306 × Organisational Support +0.620 × Negative Coping -2.097 × Academic Title. Job pressure is a significant factor leading to occupational burnout among competitive sports coaches in Sichuan Province, China, and factors such as role, interpersonal relationships and career development are closely related to occupational burnout. The sense of organizational support and negative coping strategies play a mediating role between job pressure and occupational burnout. Reducing emotional exhaustion and negative coping, enhancing emotional support and improving the academic titles of coaches can help to reduce job pressure and occupational burnout among competitive sports coaches in Sichuan Province.

Adapting Seasonal Rice Cultivation Strategies for Food Security in Response to Climate Change Impacts

An in-depth examination of the effects of climate change on rice yield in China, encompassing various rice types, is crucial for ensuring the nation’s food security. This study develops an “economy-climate” theoretical model and employs Panel Corrected Standard Error Estimation (PCSE) on panel data spanning from 1978 to 2018, sourced from China’s primary grain-producing regions. The analysis delves into the impact of climate variables, including precipitation, temperature, and sunshine duration, on overall rice production and different rice types. Overall, the findings reveal a nonlinear relationship between precipitation, temperature, sunshine duration, and rice yield, characterized by an “inverted U-shaped” pattern. However, significant variations exist in the effects on different rice types across China’s main grain-producing areas. Increasing precipitation generally enhances early rice production across provinces and also augments mid-season and one-season-late rice production in the Inner Mongolia Autonomous Region, Hebei, Jilin, Heilongjiang, and Shandong Province. Conversely, it reduces mid-season and one-season-late rice output in Liaoning, Jiangsu, Anhui, Jiangxi, Henan, Hubei, and Hunan. Sichuan Province sees a rise in temperature favoring early and double-season-late rice production, unlike other provinces. For mid-season and one-season-late rice, temperature increases benefit output in Heilongjiang Province but not in other regions. Additionally, prolonged sunshine duration boosts early and double-season-late rice production across all provinces but does not have the same effect on mid-season and one-season-late rice in China’s primary grain-producing areas.

First report of sweet cherry root rot caused by Fusarium solani in China.

Sweet cherry (Prunus avium L.) has become an economically important fruit in China. And its cultivation area has significantly expanded over the last three decades (Wang et al. 2020; Zhao et al. 2023). In July 2023, wilting of cherry trees was observed in a cherry plantation in Wenchuan County (31°51'N, 103°56'E, altitude: 1,510 m) in Sichuan Province and approximately 27% of the trees showed symptoms of root rot including soft roots, dark brown to black lesions, yellowing and wilted leaves, and a distinct yellow-brown core discoloration of the inner root core when cut in cross-section. To isolate the causal pathogens, six infected sweet cherry plants with rootstock 'Daqingye' from Cerasus pseudocerasus were randomly selected from the orchard and then the intertwined diseased and healthy roots (5mm× 5mm × 2mm) were washed with sterile water to remove surface soil. The root samples were surface sterilized with 75% ethanol for 30 seconds and NaClO for 30 seconds and washed three times with distilled water. The disinfected tissues were placed on potato dextrose agar (PDA) and incubated at 27°C in darkness for 5 days (Zhao et al. 2024). A total of nine fungal isolates with similar morphological characteristics were obtained. The colony obtained through single-spore purification displays a red reverse side and a concentric ring pattern on the front, with a sparse surface. Macroconidia were relatively slender with a curve, like sickle shape, 0 to 3 septate measuring (25.8 to 46.1) μm× (4.2 to 7.5) μm, respectively (n=20). The morphological characteristics were consistent with the description of Fusarium spp. (Li et al. 2021). Among these isolates, only HB5 was selected for additional molecular identification. Three target genes, including the internal transcribed spacer (ITS), partial translation elongation factor 1-alpha (TEF), and RNA polymerase second largest subunit (RPB2) were amplified using the primers ITS1/ITS4, TEF1-728/FTEF1-re, and fRPB2-5F/fRPB2-7r, respectively (Groenewald et al. 2013; Carbone and Kohn 1999; Reeb et al. 2004). Sequences of HB5 was deposited in GenBank (ITS, PP388208; TEF, PP580036; RPB2, PP580035). A BLAST search revealed high similarity to those of F. solani sequences with 99%, 100% and 100% respectively (MN013858.1, JF740846.1, OR371902.1), and a multilocus phylogenetic tree was generated to represent the molecular identification results. Pathogenicity studies were conducted on the rootstocks from 'Daqingye' of Cerasus pseudocerasus in 1 liter plastic flowerpots. The seedlings were incubated in a constant temperature incubator at 25°C with a humidity level of 65% for two weeks. Following the growth of green leaves, 200ml (1x106 spores/ml) of spore suspensions were poured into pots. After 4 weeks of inoculation, the same symptoms of the inoculated plants were observed consistent with those shown in the field , while control plants were inoculated with distill water with asymptomatic. The inoculated pathogen was confirmed both morphologically and molecularly as described earlier, thereby fulfilling Koch's postulates. It has been reported that Fusarium solani has been reported to cause root rot in various plants in China, including Actinidia sppt, Zanthoxylum bungeanum, Fragaria×ananassa Duch (Song et al.2022; Li et al. 2023; Zhao et al. 2024). To our knowledge, this is the first report of Fusarium solani causing root rot in sweet cherry (Prunus avium). We here also report the severity and outbreak of this disease, which has been found in other regions in recent years and may become prevalent. Further research on disease management strategies is urgently needed to protect sweet cherry production.

Feasibility of Coseismic Landslide Prediction Based on GNSS Observations: A Case Study of the 2022 Ms 6.8 Luding, China, Earthquake

Abstract On 5 September 2022, an M 6.8 earthquake struck Luding County in Sichuan Province, China, triggering extensive landslides and causing severe damages. In this study, taking this event as an exemplary case study, we test the feasibility of fast earthquake-induced landslide prediction utilizing Global Navigation Satellite System (GNSS) observations. Particularly, we construct finite-slip models based on static offsets and 1 Hz displacement waveforms. Employing these slip models, physics-based simulation (PBS) is applied separately to obtain peak ground velocity (PGV). The PGVs are then integrated into landslide spatial distribution probability prediction based on the Deep Forest algorithm. Our results show that the predicted landslides probability distribution of fast inversion models using static and high-rate GNSS data align well with the landslide catalog. Furthermore, high-rate GNSS data can improve the model performance by providing the evolution information of rupture. In addition, we also derive PGV from the empirically regressed ground-motion prediction equations (GMPEs) and incorporate it into landslide prediction. The GMPEs exhibits an advantage in terms of prediction recall for landslides and a relatively reduced accuracy compared with the PBS. Despite the inherent uncertainties in this study, based on the case study of the 2022 M 6.8 Luding earthquake, we utilize GNSS data and present a set of methods for real-time landslide prediction. The achieved model performance is relatively satisfactory, considering the challenges and uncertainties involved.

Entrepreneurial orientation, entrepreneurial action learning, and entrepreneurial performance of SMEs in the post-pandamic era: The moderating role of dynamic capabilities

This study aims to examine the relationship between the entrepreneurial orientation, entrepreneurial action learning, and entrepreneurial performance of small and medium-sized enterprises (SMEs) against the backdrop of the post-pandemic era while also exploring the moderating role of dynamic capability. Data from 629 SMEs in Sichuan Province was collected, and a partial least squares structural equation model (PLS-SEM) was employed for data analysis. The results indicate that entrepreneurial orientation has a positive relationship between entrepreneurial action learning, entrepreneurial action learning, and entrepreneurial performance. Entrepreneurial action learning mediates the relationship between entrepreneurial orientation and entrepreneurial performance. The moderation analysis further indicated that dynamic capability is a moderating variable in the relationship between entrepreneurial orientation and entrepreneurial performance and between entrepreneurial action learning and entrepreneurial performance. The practical contribution of this study lies in its provision of specific directions and recommendations for enhancing the entrepreneurial performance of SMEs.

Potential Controlling Factors and Landslide Susceptibility Features of the 2022 Ms 6.8 Luding Earthquake

On 5 September 2022, a Ms 6.8 earthquake struck Luding County, Ganzi Tibetan Autonomous Prefecture, Sichuan Province, China. This seismic event triggered over 16,000 landslides and caused serious casualties and infrastructure damages. The aim of this study is to perform the detailed landslides susceptibility mapping associated with this event based on an updated landslide inventory and logistic regression (LR) modeling. Firstly, we quantitatively assessed the importance of different controlling factors using the Jackknife and single-variable methods for modeling landslide occurrence. Subsequently, four landslide susceptibility assessment models were developed based on the LR model, and we evaluated the accuracy of the landslide susceptibility mappings using Receiver Operating Characteristic (ROC) curves and statistical measures. The results show that ground motion has the greatest influence on landslides in the entire study area, followed by elevation, while distance to rivers and topographic relief have little influence on the distribution of landslides. Compared to the NEE plate, PGA has a greater impact on landslides in the SWW plate. Moreover, the AUC value of the SWW plate significantly decreases for lithological types and aspect, indicating a more pronounced lithological control over landslides in the SWW plate. We attribute this phenomenon primarily to the occurrence of numerous landslides in Permian basalt and tuff in the SWW plate. Otherwise, the susceptibility results based on four models indicate that high-susceptibility areas predicted by different models are distributed along both sides of seismogenic faults and the Dadu Rivers. Landslide data have a significant impact on the model prediction results, and the model prediction accuracy based on the landslide data of the SWW plate is higher.

Green space coverage versus air pollution: a cloud-based remote sensing data analysis in Sichuan, Western China

ABSTRACT Air pollution is the greatest health risk to human health, as acknowledged in several Sustainable Development Goals (SDG), such as SDG-1, SDG-3, SDG-7, and SDG-11. Despite global comprehension of the positive effect of Green Space Coverage (GSC) on mitigating air pollution, investigating the impact of different GSC types has received little attention. Here, we utilized multiple air pollution data and a cloud-computing platform to examine the role of different GSC types in mitigating NO2 and PM2.5 pollutants across 2019 and 2022 in Sichuan Province, China. We classified GSC areas into tall GSC and short GSC classes, taking into account the recognized importance of vegetation height in prior studies. Our analysis revealed that tall GSCs exhibit lower pollutant levels across all areas studied, indicating a potential correlation between GSC height and pollution mitigation efficacy. Furthermore, in high human activity areas, while tall GSC emerged as effective sinks for PM 2.5 compared to short GSC (25% and 20% lower average annual in 2019 and 2022, respectively), their performance in reducing NO2 pollutant levels was relatively limited (9% and 4% lower average annual in 2019 and 2022, respectively). These findings can contribute to urban planning and environmental management.

New and Interesting Pine-Associated Hyphomycetes from China.

Pine trees play a crucial role in the forests of Sichuan Province, boasting rich species diversity and a lengthy evolutionary history. However, research and investigation on fungi associated with pine trees are insufficient. This study investigated the diversity of hyphomycetes fungi associated with pine trees in Sichuan Province, China. During the survey, we collected five specimens of hyphomycetes from branches and bark of species of Pinus. Five barcodes were selected for study and sequenced, including ITS, SSU, LSU, TEF1, and RPB2. Morphological examination and multi-locus phylogenetic analyses revealed three new species, viz. Catenulostroma pini sp. nov. within Teratosphaeriaceae, Kirschsteiniothelia longisporum sp. nov. within Kirschsteiniotheliaceae, Sporidesmiella sichuanensis sp. nov. within Junewangiaceae, and two known species, Paradictyoarthrinium diffractum and P. hydei within Paradictyoarthriniaceae, which are the new host records from Pinus species. Catenulostroma pini, distinguished from other species in the genus by its unique morphology, has three conidial morphologies: small terminal helicoconidia, scolecoconidia with many septa, and phragmoconidia conidia. Kirschsteiniothelia longisporum has longer spores when compared to the other species in the genus. According to phylogenetic analysis, Sporidesmiella sichuanensis formed an independent clade sister to S. aquatica and S. juncicola, distinguished by differences in conidial size.

Air Quality Dynamics in Sichuan Province: Sentinel-5P Data Insights (2019-2023)

This study assesses air pollution in Sichuan Province, China, from January 2019 to December 2023 using Copernicus Sentinel-5P satellite data. The analysis reveals distinct seasonal variations in levels of Carbon Monoxide (CO), Nitrogen Dioxide (NO₂), Sulfur Dioxide (SO₂), and Ozone (O₃), with urban areas experiencing higher concentrations due to industrial and vehicular emissions. CO and O₃ frequently exceeded WHO guidelines, particularly in winter and summer, indicating significant health risks. While most pollutant levels remained within safety limits, the findings highlight the importance of continuous monitoring and targeted mitigation strategies to improve air quality and safeguard public health, especially in urban environments.

Phylogenetic Insights Reveal New Taxa in Thyridariaceae and Massarinaceae.

Pleosporales is a highly diverse (and the largest) order in Dothideomycetes, and it is widespread in decaying plants in various environments around the world. During a survey of fungal diversity in Sichuan Province, China, specimens of hyphomycetous and Thyridaria-like fungi were collected from dead branches of pine trees and cherry trees. These taxa were initially identified as members of Massarinaceae and Thyridariaceae through morphological examination. Phylogenetic analyses of the Thyridariaceae, combining ITS, SSU, LSU, RPB2, and TEF1 sequence data, indicated a distinct clade sister to Pseudothyridariella and Thyridariella, distinct from any genus in the family. Thus, a new genus, Vaginospora, is proposed to accommodate the type species Vaginospora sichuanensis, which is characterized by semi-immersed globose to oblong ascomata with an ostiolar neck, cylindrical to clavate asci with an ocular chamber, and hyaline to dark brown, fusiform, 3-5-transversely septate ascospores with an inconspicuous mucilaginous sheath. Based on the morphological comparisons and multi-locus phylogenetic analyses (ITS, SSU, LSU, RPB2, and TEF1) of the Massarinaceae, we have identified three collections belonging to the genus Helminthosporium, leading us to propose H. filamentosa sp. nov., H. pini sp. nov., and H. velutinum as a new host record. According to Phylogenetic analysis, H. pini formed an independent clade sister to H. austriacum and H. yunnanense, and H. filamentosa represents the closest sister clade to H. quercinum. Helminthosporium pini is distinct from H. austriacum by the shorter conidiophores and H. yunnanense by the longer and wider conidia. The H. filamentosa differs from H. quercinum in having longer conidiophores and smaller conidia. This study extends our understanding of diversity within Thyridariaceae and Helminthosporium. Our findings underscore the rich biodiversity and potential for discovering novel fungal taxa within these groups.

Spatio-temporal variation and influencing factors of ecol-environment quality in Jiuzhaigou County, Sichuan, China under seismic disturbance.

Accurately monitoring and evaluating changes in ecological environment quality under earthquake disturbances is of great significance for the restoration and protection of regional ecological environment. In view of the "8·8" earthquake in Jiuzhaigou County in 2017, we used high-precision remote sensing image to analyze the vege-tation damage caused by the earthquake, and calculated remote sensing ecological index (RSEI) for the pre-earthquake period, post-earthquake period and 3-year recovery period based on GEE platform to analyze the spatio-temporal variation of ecological environment in Jiuzhaigou County, Sichuan Province. Then, we used geodetector to reveal the influencing factors of spatio-temporal variations in ecological restoration. The results showed that the fractional vegetation cover of Jiuzhaigou County decreased from 0.71 before the earthquake to 0.69 after the earthquake. The area of higher coverage zone decreased by 310.78 km2, while the area of others increased. The mean RESI decreased from 0.50 in the pre-earthquake period to 0.42 in the post-earthquake period, and increased to 0.50 after the 3-year recovery period. The ecological environment quality in the three period was mainly at the good and ave-rage levels, and it was distributed in the central and southern mountains and the eastern river valley. Annual precipitation, elevation, wet and greenness were the main factors controlling ecological quality restoration in Jiuzhaigou County, and the increases in the interaction among these factors would affect the spatial variations of regional ecological environment quality restoration.

Factors related to the disaster preparedness of patients on haemodialysis from Sichuan, China, during COVID-19: A cross-sectional study.

This study aimed to investigate personal preparedness among patients on haemodialysis (HD) and to examine the relationship among sociodemographic characteristics, attitudes toward disaster preparedness and personal preparedness behaviours during natural disaster incidents. A cross-sectional survey was conducted. A convenience sampling method was used. A total of 446 participants from six areas of Sichuan province completed the online questionnaire study from February 27 to March 13, 2022. Sociodemographic characteristics, attitudes toward disaster preparedness and personal preparedness behaviours were measured. Descriptive statistics were used to analyse sociodemographic characteristics and attitudes toward disaster preparedness. The relationship among sociodemographic characteristics, attitudes toward disaster preparedness and personal preparedness behaviours were assessed using ordinal regression. Statistical significance was defined as p < 0.05. A total of 446 participants completed the survey. Of these, 42.15% (N = 188) were poorly prepared, 26.23% (N = 117) were moderately prepared and 31.61% (N = 141) were highly prepared. Ordinal regression showed that knowing about disaster preparedness (Odds Ratio (OR) = 1.691, 95% Confidence Interval (CI) = 1.081-2.644, p = 0.021), participating in disaster evacuation exercises (OR = 2.519, 95% CI = 1.595-3.977, p < 0.001) and learning about disaster preparedness (OR = 2.421, 95% CI = 1.542-3.802, p < 0.001) were associated with high preparedness. Compared to patients with a university degree or higher, patients with a junior high school education or lower (OR = 3.491, 95% CI = 1.760-6.925, p < 0.001) and senior high school degree (OR = 2.052, 95% CI = 1.038-4.057, p = 0.039) were associated with high preparedness. Patients who felt very confident and could deal with all their needs (OR = 3.878, 95% CI = 2.904-7.181, p < 0.001) or patients who felt confident and could meet some of their needs (OR = 1.949, 95% CI = 1.124-3.379, p = 0.017) had higher preparedness than those who felt less confident and were not well prepared to take care of their needs. After obtaining each participant's consent, they filled out the online questionnaire using their own or a relative's cell phone while undergoing HD. It is essential that patients should be educated not only on medical specialty topics, but also on general disaster preparedness. Medical institutions should improve and reinforce preparation training among targeted populations. The low level of preparedness is partly due to the lack of participation of patients in disaster preparedness programs. Dialysis center managers should be urged to implement such programs at their centers.

Current Situation and Influencing Factors of Caregivers' Pressuring Feeding Style in Infants of 6-11 Months Old in Rural Areas of Sichuan Province

Objective To investigate the status and influencing factors of pressuring feeding style among caregivers in remote rural areas of Sichuan province. Methods Multistage sampling was conducted to select infants of 6-11 months old who had received complementary food and their caregivers in remote rural areas of Sichuan province.A questionnaire was used to collect sociodemographic characteristics of infants and their caregivers,pressuring feeding behaviors,feeding environment,and caregivers' negative emotions.Quantile regression was employed to analyze the factors influencing pressuring feeding among caregivers of infants. Results A total of 1358 pairs of infants and their caregivers were included,with the pressuring feeding behavior score of 11 (8,14).Parity was the protective factor for caregivers' pressuring feeding (β25=-1.17,P<0.001;β50=-1.40,P=0.002;β75=-2.18,P<0.001).Whether infants played with toys while eating (β25=1.00,P<0.001;β50=1.20,P=0.003;β75=1.42,P<0.001) and whether infants watched TV/mobile phones (β25=0.50,P=0.048;β50=1.07,P=0.004) were the risk factors.At the 75th percentile,caregivers' negative emotions were the risk factor for pressuring feeding (β75=0.94,P=0.015).Caregivers' education background (β25=0.83,P=0.034;β50=0.87,P=0.021) and family income (β75=1.09,P=0.012) were also significantly associated with pressuring feeding scores at different quartile points. Conclusion Pressuring feeding behaviors of caregivers in remote rural areas of Sichuan province need to be improved.Based on the characteristics of infants and their families,guidance should be carried out to improve the feeding environment and the mental health of caregivers,thereby promoting reasonable feeding behaviors among caregivers of infants in rural areas.

Mapping the Distribution of Curculio davidi Fairmaire 1878 under Climate Change via Geographical Data and the MaxEnt Model (CMIP6).

Curculio davidi is a major pest in chestnut-producing regions in China, and there have been many studies on its occurrence, biological characteristics, and management strategies. However, few of them have focused on the distribution changes of the pest under climate change. In this study, the MaxEnt model (version 3.3.4) and ArcGIS software (version 10.8) were first employed to map the current and future (2050 s and 2080 s) suitable habitat distribution of the weevil under climate change (CMIP 6: SSP1-2.6, SSP2-4.5, and SSP5-8.5). The results indicate that the highly suitable areas for C. davidi are mainly concentrated in Hubei, Henan, Anhui, Jiangxi, Jiangsu, Zhejiang, the coastal areas of Shandong, and eastern Guizhou, northwestern Hunan, and northeastern Sichuan provinces in China. Through the Jackknife test of 19 climate factors, six climate factors affecting the distribution of C. davidi were identified, with precipitation from July (Prec7), precipitation of warmest quarter (Bio18), and temperature seasonality (standard deviation × 100) (Bio4) contributing a combined percentage of 86.3%. Under three different climate scenarios (CMIP 6: SSP1-2.6, SSP2-4.5, and SSP5-8.5), the area of moderately suitable regions is projected to increase by 22.12-27.33% in the 2050 s and by 17.80-38.22% in the 2080 s compared to the current distribution, while the area of highly suitable regions shows a shrinking trend. This study provides data support for the management strategies of C. davidi and offers new insights into the dynamic changes of similar forestry pests.

The Impact of Harsh Parenting on the Self-efficacy of Chinese Middle School Students

As the level of education for all increases, family education is receiving more and more attention, and different parenting styles will have different impacts on children. This article mainly studies the impact of harsh parenting on Chinese middle school students' self-efficacy. In this study, 120 students of a middle school in Chengdu City, Sichuan Province, were recruited, and a questionnaire survey was conducted using stratified cluster sampling method, and 120 valid data were obtained. The questionnaire included the respondents' basic information, harsh parenting scale, and general self-efficacy scale, and the Cronbach's of the data was 0.76. Through comprehensive analyses, it is concluded that middle school students' self-efficacy was negatively correlated with their parents' harsh parenting, with the father's harsh language being the most significant in relation to the children's self-efficacy. In order to highlight the negative effects of harsh parenting and serve as a reminder to parents to be conscious of their own parenting style, this study aims to ascertain how strict parenting will impact children's sense of self-efficacy.

Positive and negative factors of the influence of new media and the digital environment on ideal and belief education among university students in China

The authors identity the relationship between the positive and negative aspects of social media and the ideal belief learning and behavior of university students. The cluster sampling method was adopted in the paper, including Guangdong, Shandong, Henan, Sichuan, and Jiangsu provinces. A total of 1014 questionnaires were distributed to a purposive sample of university students between the ages of 16 and 35. The authors applied the uses and gratifications theory to study students’ social media behavior. This study identified 18 positive and negative effects of social media. Noteworthy positive outcomes attributed to social media in fostering ideals and beliefs encompass heightened awareness, enhanced communication facilitation, convenient connectivity, reduced expenses on educational materials, improved social and communication proficiencies, as well as diminished stress levels. The negative effects of new media and the Internet include a lack of critical thinking, a waste of time, dysgraphia, disrupted connection to learning, students’ laziness, and health risks.

Social support and sleep quality in people with schizophrenia living in the community: the mediating roles of anxiety and depression symptoms.

Research has demonstrated that higher social support is associated with better psychological health, quality of life, cognition, activities of daily living, and social participation, but the relationship between social support and sleep quality remains unknown. This study aims to investigate the mediating effects of anxiety and depression in the relationship between social support and sleep among community-dwelling patients with schizophrenia. Purposive sampling was used to collect face-to-face data from 1,107 community-dwelling patients with schizophrenia in Chengdu, Sichuan Province, China, between April and July 2023. The Athens Insomnia Scale (AIS) was used to assess sleep quality; the Generalized Anxiety Disorder 7-item scale (GAD-7) was utilized to evaluate anxiety symptoms; and the Patient Health Questionnaire-9 (PHQ-9) was employed to assess depressive symptoms. The mediating effect of anxiety and depression symptoms was assessed using the bootstrap method via Model 6 (Serial multiple mediator model) of the SPSS PROCESS macro. Among the 1,107 participants, the proportions of people with schizophrenia experiencing anxiety, depressive symptoms, and poor sleep quality were 22.8, 37.7, and 42.1%, respectively. Mediation analyses indicated that although social support had no direct effect on sleep quality, anxiety and depressive symptoms fully mediated the relationship between social support and sleep quality. Patients with schizophrenia experience low levels of social support and poor sleep quality. To enhance the sleep quality of individuals with schizophrenia, all levels of society (government, medical institutions, and communities) must pay more attention to mental health. Implementing diverse intervention measures to strengthen social support and improve symptoms of anxiety and depression should be considered. This approach may potentially lead to an improvement in sleep quality among individuals with schizophrenia.
