广东省不同族群农村成年人体质状况研究

本文以广东省不同族群农村成年人为研究对象,运用文献资料法、逻辑分析法、数理统计法等研究方法,对广东省不同族群农村成年人身体素质和身体机能状况进行分析,并对不同族群农村成年人的BMI进行相关研究。结果显示:广东省不同族群农村成年人体重男女均呈持续增长态势,在30~34岁时是快速增长期,至45~49岁时BMI超重和肥胖检出率达到峰值;不同族群的体质水平指标表现为广府人较好,潮汕人较差;受遗传因素的影响,广东省不同族群之间体质水平差别较大。     

The Relationship Between Psychopathology and Shame in Secondary School Students

This study investigated the relationship between psychopathology and shame. Three hundred and thirty-one Secondary 2 students from Singapore participated in the study. All students completed a self-report questionnaire consisting of the Anxiety and Depression scales of the Behavior Assessment System for Children (BASC), the short version of the Aggression Questionnaire (AQ), and the Internalized Shame Scale (ISS). As predicted, students in the comorbid group at-risk for anxiety, depression and aggression, had significantly higher shame scores compared with at-risk students in all the other three single-disordered groups (anxiety-only, depression-only, or aggression-only) as well as students in the control group. Also, as expected, the control group scored significantly lower compared to all other single-disorder groups and the comorbid group. Implications of these findings with regard to comorbidity of psychopathology and its relationship to shame, classroom interventions, as well as implications pertaining to teachers' and counsellors' work with at-risk students will be discussed.

Prevalence and correlates of meeting the muscle-strengthening exercise recommendations among Chinese children and adolescents: Results from 2019 Physical Activity and Fitness in China—The Youth Study

PurposeThis study aimed to describe the national prevalence of Chinese children and adolescents who met the World Health Organization muscle-strengthening exercise (MSE) recommendations and identify correlates of meeting the MSE recommendations.MethodsCross-sectional data from the 2019 Physical Activity and Fitness in China—The Youth Study, a nationally representative sample of Chinese children and adolescents (n = 80,413; mean age = 13.7 years; 53.9% girls) and their parents, were analyzed. Children and adolescents who reported engaging ≥3 days (up to 7 days) of MSE per week were classified as meeting the MSE recommendations. MSE, demographics, lifestyle behaviors (sport participation, moderate-to-vigorous physical activity, screen time, and sleep duration), exercise intention, peer and parental support, and parental MSE participation were assessed through self-reports. Logistic regression models were used to determine the correlates of meeting the MSE recommendations. The analyses were completed in 2020.ResultsOverall, 39.3% of children and adolescents met the MSE recommendations. Girls, 10th–12th graders, minorities, those from lower income households and those from families with lower parental education were less likely to meet the MSE recommendations. Children and adolescents who were proficient in ≥2 sports were more likely to meet the MSE recommendations (adjusted odds ratio (aOR) = 1.44, 95% confidence interval (95%CI): 1.26–1.65), as were those with more moderate-to-vigorous physical activity (aOR = 1.57, 95%CI: 1.53–1.61). Additionally, children and adolescents with high exercise intention (aOR = 1.60, 95%CI: 1.51–1.69), those whose parents met the adult MSE recommendations (aOR = 1.46, 95%CI: 1.40–1.52), and those who received high peer (aOR = 1.27, 95%CI: 1.20–1.34) and parental support (aOR = 1.07, 95%CI: 1.04–1.12) were more likely to meet the MSE recommendations.ConclusionLess than two-fifths of Chinese children and adolescents met the World Health Organization MSE recommendations. The correlates identified in our study can help inform the development of school and community based strategies and policies to enhance participation in MSE and improve muscular fitness of all Chinese children and adolescents.     

设计性实验《电阻测量与应用》可行性分析

综合设计性实验在大学物理实验中要占有一定比例,但是原理简单、容易操作的实验很少.在电阻测量中因实验目的不同其实验内容、实验方法也不同,具有很大的操作性,在工业生产中电阻式传感器在测试技术上的应用也比较多,其原理简单易懂,涉及的方面也比较广,因此《电阻的测量与应用》是可以作为一个设计性实验开设.     

Are K-12 learners motivated in physical education? A meta-analysis

Previous studies devoted to K-12 learner motivation in physical education share a general assumption that students may lack motivation. This meta-analytic study examined published original studies (n = 79) to determine students' motivation level and the association between motivation and outcomes. Original means of motivation measures were converted and aggregated to determine motivation levels. Correlation effect sizes were calculated to determine the association between motivation and outcome measures. The analyses revealed that K-12 students are motivated regardless of the theoretical constructs used in the studies (M > 50). The correlation effect sizes (r = .20-.30, p < .05) indicate a weak association between motivation and outcome. The findings suggest a need to involve meaningful learning and pedagogy variables in motivation research.
