Unsociability and social adjustment in Chinese preschool migrant children: the moderating role of receptive vocabulary.

Peer relationships play an indispensable role in the social, emotional, and cognitive development of children. However, children exhibiting social withdrawal, such as unsociability, may face challenges in social adjustment. In collectivistic cultures like China, unsociability may be perceived negatively, aligning poorly with collective norms. The objective of the present investigation was to examine the associations between unsociability, receptive vocabulary, and indicators of social adjustment in a cohort of young migrant children residing in urban regions of mainland China. The study mainly aimed to investigate the potential moderating influence of receptive language on these associations. The study involved 148 young children (82 boys, 66 girls, Mage = 62.32 months, SD = 6.76) enrolled in preschools or kindergartens in Shanghai, People's Republic of China. Multiple sources of assessment were utilized, encompassing evaluations from mothers (about child unsociability), teacher (assessing social adjustment), and standardized tests (measuring receptive vocabulary). The results indicated that the relations between unsociability and peer exclusion were more positive among children with lower levels of receptive vocabulary but not significant for children with higher levels of receptive vocabulary. Similarly, the relations between unsociability and peer exclusion were more negative among children with lower levels of receptive vocabulary but not significant for children with higher levels of receptive vocabulary. Thus, this study informs us about how receptive vocabulary is jointly associated with unsociable children's development. As well, the findings highlight the importance of considering the meaning and implication of unsociability in Chinese culture.

Research on the Effectiveness of the Training of Nosocomial Infection Control Specialist Nurses under the Background of the New Crown Epidemic Based on Competence-based Theory.

Background: Coronavirus disease 2019 is highly contagious and has the potential to cause nosocomial infections, has placed a strong pressure on worldwide healthcare systems over the last years. Nosocomial infection has many influencing factors, among which the unreasonable operation of nurses accounts for 30.0%-50.0%. Therefore, strengthening the professional skill training of nurses is of great significance in reducing the nosocomial infection rate. Objective: This research aimed to explore the effectiveness of the training of nosocomial infection control on the competencies of specialist nurses under the background of the new crown epidemic based on competency-based theory. Design: This was a retrospective study. Setting: This study was performed in Dongfang Hospital, Affiliated to Tongji University. Participants: A total of 84 key nurses, each of them recommended by one department from June 2020 to June 2021, were chosen as study subjects, and they could actively participate in the training. Interventions: Nurses received systematic and standardized training based on competency-based theory under the background of coronavirus disease 2019, including focus group meeting, training of core emergency capability, teaching training and contingency plan for COVID-19 infection. Primary Outcome Measures: (1) core competence (2) job fit (3) core emergency response for major infectious diseases, and (4) nurses' satisfaction. All these primary outcomes can reflect the competencies of specialist nurses after training. Results: The scores in critical thinking and scientific research, clinical nursing, ethics and legal practice, professional development, education consulting and professional knowledge, professional skills, comprehensive quality, and professional ability of nurses training were higher than those before (P = .000). After training, the scores in relevant matters needing attention (international rescue, bioterrorist attacks, and infectious disease emergencies after natural disasters), filling in the People's Republic of China Infectious Disease Report Card, and the scope of reporting infectious disease emergencies were all higher than before (P = .000). All nurses had relatively high satisfaction with the curriculum setting and assessment form, with satisfaction of 100.0%, followed by training duration, with satisfaction of 92.86%. Conclusion: Under the background of coronavirus disease 2019, based on competence-based theory, training of nosocomial infection control specialist nurses could improve their core competence, job fit, and core emergency response capabilities, with high satisfaction. Under the background of the normalization of the prevention and control of the novel coronavirus pneumonia epidemic, the training model based on competence-based theory of nurses is worth promoting.

Social avoidance and social adjustment in Chinese preschool migrant children: the moderating role of teacher-child relationships.

Objectives: This study aimed to explore the moderating role of teacher-child relationships in the relations between social avoidance and social adjustment (i.e., prosocial behavior, peer exclusion, and anxious-fearful behavior) in Chinese migrant preschoolers. Methods: Participants were 148 migrant children aged 4-6 years (82 boys, Mage = 62.32, SD = 6.67) attending kindergartens in Shanghai, People's Republic of China. Mothers reported children's social avoidance, and teachers rated teacher-child relationships and children's social adjustment. Results: Results indicated that social avoidance was positively related to peer exclusion and negatively related to prosocial behavior. Teacher-child relationships moderated those associations. Specifically, teacher-child closeness buffered the relationship between social avoidance and peer exclusion, whereas teacher-child conflict exacerbated the relations between social avoidance and peer exclusion and anxious-fearful behavior. Conclusion: The current finding informs us of the importance of improving teacher-child closeness and reducing teacher-child conflict to buffer the negative adjustment among socially avoidant young children who migrated from rural-to-urban China. The findings also highlight the importance of considering the meaning and implication of social avoidance for migrant preschoolers in Chinese culture.

Social Avoidance and Social Adjustment in Chinese Preschool Migrant Children: The Moderating Role of Household Chaos and Gender.

The present study explored the moderating role of household chaos and gender in the relation between social avoidance and social adjustment among Chinese preschool migrant children. Participants were 148 children (82 boys, Mage = 62.63 months, SD = 0.05) from two kindergartens, Shanghai, People's Republic of China. Multi-source assessments included: (1) mother ratings of children's social avoidance; (2) mother ratings of families' household chaos; (3) teacher ratings of children's prosocial behavior, peer exclusion, interpersonal skills, and internalizing problems. Results showed that social avoidance significantly predicted peer exclusion among Chinese migrant preschoolers. Moreover, household chaos moderated the relationship between social avoidance and social adjustment. Specifically, at higher levels of household chaos, social avoidance was negatively associated with interpersonal skills. In contrast, social avoidance was not associated with interpersonal skills at a lower level of household chaos. In addition, social avoidance was positively associated with peer exclusion among boys but not girls. The current findings inform us of the importance of reducing household chaos to buffer the negative adjustment among socially avoidant young children who migrated from rural to urban China. The findings also highlight the need to pay particular attention to migrant socially avoidant boys' development in early childhood and the importance of considering the meaning and implication of social avoidance for migrant preschoolers in Chinese culture.

Occurrence and distribution of microplastics in organic fertilizers in China.

The use of organic fertilizers is becoming a routine measure of soil improvement in China, and therefore organic fertilizers are considered an emerging contributor to microplastic accumulation in farmland soils. However, little is known regarding the microplastic contents in organic fertilizers used across China. Here, we investigated the occurrence and distribution of microplastics in 102 organic fertilizer samples across 22 provincial administrative regions of China to serve as a basis for the development of better microplastic management strategies. Organic fertilizers are made of a wide variety of feedstocks, including livestock manure (chicken, cow, goat, and pig manure) and bacterial residues etc., and are mainly produced via aerobic composting. In present study, microplastics within a 0.1-5 mm range in different types of organic fertilizers were separated using a general sequential density flotation method. Microplastic abundances ranged from undetectable to 2550 items/kg, with an average value of 325 ± 511 items/kg and a detection frequency of 80.4 %. The highest microplastic abundances were detected in Beijing City (758 items/kg) and in compound organic fertilizers (average of 386 items/kg). The microplastics in organic fertilizer were primarily white/transparent (75.9 %), 1-3 mm in size (55 %), and film-shaped (39 %). Interestingly, microplastics were not detected in cow dung fertilizer, suggesting that cow dung-based fertilizers might generally contain lower microplastic levels. Moreover, organic fertilizer microplastics tended to be concentrated in provincial areas with intensive agriculture, and the input flux of microplastics from organic fertilizer into fertilized soils reached an average of 5.07 × 1012 items per year. Collectively, our findings provide key insights into the current state of microplastic levels in organic fertilizers in China and serve as a basis for the creation of novel microplastic mitigation strategies in farmland soils.

Contrasting Sleeve Gastrectomy with Lifestyle Modification Therapy in the Treatment of Polycystic Ovary Syndrome.

AIMS: To explore the feasibility of sleeve gastrectomy (SG) as a treatment for polycystic ovary syndrome (PCOS) and its potential to improve clinical efficacy in PCOS patients with symptoms of oligomenorrhea. PATIENTS AND METHODS: Twenty-four obese patients with PCOS underwent laparoscopic SG. Simultaneously, 24 obese patients with PCOS received lifestyle modification therapy (LMT). Follow-ups were conducted at 3-6 months. Weight loss, menstruation, and improvements in hirsutism and metabolic symptoms were compared. RESULTS: In the SG group, 20 patients were restored to normal menstrual cycles and ovulation at 3-6 months after surgery. Their average androgen levels decreased significantly following surgery (P=.012). Conversely, only 6 patients in the LMT group were restored to normal menstrual cycles and ovulation after receiving 3 months of treatment. Their average preoperative and postoperative androgen levels showed a nonstatistically significant decrease (P>.05). Compared with the LMT group, the SG group showed more pronounced improvements in menstruation. Additionally, body mass and body mass index were significantly reduced in patients in the SG group 3 months after the surgeries, with maximum weight loss observed at approximately 6 months after surgery. Patients who received LMT showed a gradual weight reduction such that body mass decreased significantly after 3 months (P<. 001). Compared with patients in the LMT group, patients in the SG group showed greater weight loss results (P<.0001). CONCLUSIONS: In patients with PCOS, SG resulted in more marked weight loss and better improvements in clinical symptoms compared with LMT.
