However, the selection and evaluation systems for arbitrators in China have long faced challenges such as the vague criteria for competency and an unclear professionalization path for arbitrators. To address these issues, this study is grounded in the context of actual Chinese arbitration practice and based on the competency iceberg model. Through a methodological approach encompassing literature reviews, behavioral event interviews, expert revisions, and questionnaire surveys, a Chinese Arbitrator Competency Scale was developed and validated in this study. Examination of the findings indicated that the scale needed to consist of five dimensions—communication and coordination, cognitive skills, ethical conduct, work motivation, and personality traits—and possess a total of 28 specific indicators. Confirmatory analysis of the factors demonstrates a good fit for the five-dimensional model, with each of the dimensions exhibiting high reliability and validity. This scale is innovative in integrating the competency elements with Chinese characteristics, such as commercial acumen, crosscultural mediation skills, and adaptability to the local rule of law. This research not only enriches the competency theory in regard to the field of human resource management but also provides a scientific framework of standards and measurement tools for the selection, training, and evaluation of arbitrators. It thus has significant practical value for enhancing the professionalism and international competitiveness of China's arbitration system.展开更多

To address these issues, this study is grounded in the context of actual Chinese arbitration practice and based on the competency iceberg model.

Confirmatory analysis of the factors demonstrates a good fit for the five-dimensional model, with each of the dimensions exhibiting high reliability and validity. This scale is innovative in integrating the competency elements with Chinese characteristics, such as commercial acumen, crosscultural mediation skills, and adaptability to the local rule of law. This research not only enriches the competency theory in regard to the field of human resource management but also provides a scientific framework of standards and measurement tools for the selection, training, and evaluation of arbitrators. It thus has significant practical value for enhancing the professionalism and international competitiveness of China's arbitration system.

文摘Although the benefits of physical activity are established across all age groups,researchers have recently noted that there is uncertainty as to which correlates and determinants of physical activity contribute to well-informed interventions and policies,particularly for the time frame of early childhood.The following narrative review highlights salient factors related to physical activity during early childhood,particularly in the United States,with respect to a socioecological framework.Discussion of factors at the individual(demographic,genetic),interpersonal(family support and perceptions of competence),organizational(e.g.,preschool attended,preschool quality,teacher characteristics),community(availability,use,and perceptions of play spaces),and policy levels is included.While researchers often work within a public health framework that focuses on moderate-to-vigorous physical activity,or total(light-to-vigorous)physical activity,this may not fully align with how young children move.The importance of structured and unstructured play,risky play,and nature-based play are highlighted.Implications for basic and applied scientists,clinicians,and practitioners are addressed.Suggestions for future work include consideration of the context of physical activity,associations with other health behaviors,and further examination of the interpersonal and community level factors.

文摘BACKGROUND Children with critical acute abdominal conditions often undergo intestinal stoma surgery.AIM To explore the impact of a visual mobile terminal-based extended care model on caregiver competence for children with enterostomies.METHODS One hundred twenty children with enterostomies and their caregivers in a children's hospital in Beijing were divided into a control group and a study group.The control group(60 cases)received traditional telephone follow-up for continuity of care,while the study group(60 cases)used a visualization mobile terminal-based care model.The incidence of stoma-related complications,caregiver burden scale,and competence scores of children with stoma were compared between the two groups.RESULTS The primary caregiver burden score in the study group(37.22±3.17)was significantly lower than that in the control group(80.00±4.47),and the difference was statistically significant(P<0.05).Additionally,the caregiving ability score of the study group(172.08±3.49)was significantly higher than that of the control group(117.55±4.28;P<0.05).The total incidence of complications in the study group(11.7%,7/60)was significantly lower compared to the control group(33.3%,20/60;χ2=8.086,P=0.004).CONCLUSION The visual mobile terminal-based care model reduces caregiver burden,improves home care ability,lowers the incidence of complications and readmission rates,and supports successful second-stage reduction surgery for children with enterostomies.

文摘BACKGROUND Brain-computer interface(BCI)technology is rapidly advancing in psychiatry.Informed consent competency(ICC)assessment among psychiatric patients is a pivotal concern in clinical research.AIM To analyze the assessment of ICC and form a framework with multi-dimensional elements involved in ICC of BCI clinical research among psychiatric disorders.METHODS A systematic review of studies regarding ICC assessments of BCI clinical research in patients with six kinds of psychiatric disorders was conducted.A systematic literature search was performed using PubMed,ScienceDirect,and Web of Science.Peer-reviewed articles and full-text studies were included in the analysis.There were no date restrictions,and all studies published up to February 27,2025,were included.RESULTS A total of 103 studies were selected for this review.Fifty-eight studies included ICC factors,and forty-five were classified in ICC related ethical issues of BCI research in six kinds of psychiatric disorders.Executive function impairment is widely recognized as the most significant factor impacting ICC,and processing speed deficits are observed in schizophrenia,mood disorders,and Alzheimer’s disease.Memory dysfunction,particularly episodic and working memory,contributes to compromised ICC.Five core ethical issues in BCI research should be addressed:BCI specificity,vulnerability,autonomy,dynamic ICC,comprehensiveness,and uncertainty.CONCLUSION A Five-Dimensional evaluative framework,including clinical,ethical,sociocultural,legal,and procedural dimensions,is constructed and proposed for future ICC research in BCI clinical research involving psychiatric disorders.

文摘This study aims to investigate the current status of AI competencies among Chinese high school students using quantitative research methods.By integrating UNESCO’s AI Competency Framework for Students with China’s educational practices,a questionnaire was developed.Altogether,300 students from eight high schools joined the research.SPSS 26.0 was used for reliability and validity tests,exploratory factor analysis,and group difference analysis.The results show that the questionnaire has good reliability and validity(Cronbach’sα=0.974,KMO=0.912,Bartlett’s test of sphericity was significant with p<0.001,cumulative variance explained 72.0%).Besides,Chinese high school students’AI competencies exhibit a typical pattern of“strong in technology,weak in ethics,and insufficient in creativity”,with technical application ability(mean=3.7)significantly higher than ethical assessment(mean=3.0)and system design(mean=2.8).What’s more,students in the eastern region have significantly better overall competencies than those in the central and western regions(p<0.05),with the largest gap in the technical application dimension(mean difference=0.7)and the smallest gap in the ethical dimension(mean difference=0.3).The study recommends optimizing high school curricula by adding modules for ethical debates and interdisciplinary projects and promoting equitable distribution of educational resources.This research empirically supports global AI education standardization and offers a scientific basis for AI education policies and curriculum design in China’s high schools.
