具有电荷和磁矩的天体的引力效应     

郭鸿钧 《韩山师范学院学报》1998,19(2):50-53,56

本文根据文[1]得到的具有电荷和磁矩的天体的度规，计算了这类天体的无限红移面和这种天体的引力场中光线的引力偏转，雷达信号的延迟，结果表明，电荷和磁矩的存在，减小了引力质量产生的相应效应，当电荷和磁矩不存在时，所得结果均退化为Schwarzshild天体的情况。  相似文献

Want to improve sexual health education for girls? Include body image     

Virginia Ramseyer Winter  Michaella Ward  Sarah Pilgrim  Mackenzie Cook  Alison Summers 《American journal of sexuality education》2019,14(2):152-164

Research suggests body image is related to sexual behaviors, which can impact sexual health across the lifespan. This paper aims to explain the necessity for including body image content in sexuality education to improve outcomes among girls. Our recommendations, supported by theory and empirical research include (a) an assessment of existing curricula; (b) designing new, theoretically-informed curricula; (c) using innovative technology in sex education; (d) rigorous evaluation of existing and new curricula; and (e) revising the National Sexuality Education Standards. These recommendations are discussed after providing the necessary background and rationale.  相似文献   

Body mass index, waist circumference, and cardiometabolic risk factors in young and middle-aged Chinese women     

Xin Ying  Zhen-ya Song  Chang-jun Zhao  Yan Jiang 《Journal of Zhejiang University. Science. B》2010,11(9):639-646

Objective: To assess the associations between body mass index (BMI), waist circumference (WC), and cardiometabolic risk factors in young and middle-aged Chinese women. Methods: A total of 3011 women (1938 young women, 1073 middle-aged women), who visited our health care center for a related health checkup, were eligible for study. BMI and WC were measured. The subjects were divided into normal and overweight/obesity groups based on BMI, and normal and abdominal obesity groups based on WC. Cardiometabolic variables included triglyceride (TG), high density lipoprotein cholesterol (HDL-C), fasting blood glucose (FBG), homeostasis model assessment of insulin resistance (HOMA-IR), and blood pressure (BP). Results: The prevalence of overweight/obesity was significantly higher in middle-aged women (32.4%) than in young women (12.0%). The prevalence of abdominal obesity was also higher in middle-aged women (60.3%) than in young women (36.2%). There were significant differences in the comparison of all related cardiometabolic variables between different BMI (or WC) categories in young and middle- aged women groups, respectively. After adjustment for age, partial correlation analysis indicated that both BMI and WC were correlated significantly with all related cardiometabolic variables. After adjustment for age and WC, although the correlation coefficient r′was attenuated, BMI was still correlated significantly with all related cardiometabolic variables in young and middle-aged women. After adjustment for age and BMI, partial correlation analysis showed that WC was correlated significantly with TG, FBG, HOMA-IR, and HDL-C in young women and significantly with TG, HOMA-IR, and HDL-C in middle-aged women. Conclusions: The prevalence of overweight/obesity and abdominal obesity was high in Chinese young and middle-aged women. BMI was a better predictor of cardiovascular disease and diabetes than WC in young and middle-aged women, and moreover, measurement of both WC and BMI may be a better predictor of cardiovascular disease and diabetes mellitus than BMI or WC alone.  相似文献

阶层化与城市老年人体育参与     

徐建清 《福建体育科技》2012,(4):4-7

对中国社会综合调查(CGSS2006)数据进行二次资料分析,发现不同教育程度、职业的管理位置、居住空间城市老年人的健身锻炼情况有显著性差异。退休前不同的技术职称等级、行政级别、所在单位不同等级、不同幸福感、生活满意感和社会经济地位主观认同的城市老年人对是否锻炼有显著性差异。性别、年龄没有成为区分体育锻炼行为差异的变量。应用社会分层和社会心理学研究成果分析认为社会客观位置与锻炼行动之间存在"结构化"关系,具有追求健康、非生产性、炫耀式休闲特征的身体锻炼行为成为文化资本的重要组成部分,不断被用来强化社会地位群体的边界。研究进一步对体育部门职能方向提出了可行性建议。  相似文献
