Comparing cumulative index and factor analytic approaches to measuring maltreatment in the National Longitudinal Study of Adolescent to Adult Health     

《Child abuse & neglect》2019

Child maltreatment is a complex and multifaceted construct in need of advanced statistical techniques to improve its measurement. The current study compared the predictive utility of a cumulative index to a factor analytic approach for constructing a measure of maltreatment. Data were from Waves III and IV of the National Longitudinal Study of Adolescent to Adult Health (Wave III: n = 14,800; Wave IV: n = 12,288). As adults, participants retrospectively reported on their childhood experiences of physical abuse, sexual abuse, emotional abuse, physical neglect, supervisory neglect, and social services investigations. Both the cumulative index and a two-factor solution showed evidence of convergent validity, predicting lifetime incidence of homelessness, being paid for sex, and various measures of running away or living apart from biological parents, and prospectively predicting depression, substance use, and criminal behavior. The latent variables, derived from a factor analytic approach, had greater explanatory power for many outcomes compared to the cumulative index, even when controlling for sociodemographic variables. Results suggest that factor analysis is a better methodology than a cumulative index for measuring maltreatment in large datasets when explanatory power for external outcomes is of greatest concern.  相似文献

Carnosine in health and disease     

Guilherme Giannini Artioli  Craig Sale  Rebecca Louise Jones 《European Journal of Sport Science》2019,19(1):30-39

Abstract

Carnosine was originally discovered in skeletal muscle, where it exists in larger amounts than in other tissues. The majority of research into the physiological roles of carnosine have been conducted on skeletal muscle. Given this and the potential for muscle carnosine content to be increased with supplementation, there is now a large body of research examining the ergogenic effects (or otherwise) of carnosine. More recent research, however, points towards a potential for carnosine to exert a wider range of physiological effects in other tissues, including the brain, heart, pancreas, kidney and cancer cells. Taken together, this is suggestive of a potential for carnosine to have therapeutic benefits in health and disease, although this is by no means without complication. Herein, we will provide a review of the current literature relating to the potential therapeutic effects of carnosine in health and disease.  相似文献   

跳远助跑速度变化对起跳效果的影响——国内外优秀运动员与我院选手的比较分析   总被引：1，自引：0，他引：1  

程万才 《西安体育学院学报》2003,20(2):78-79

笔者采用高速摄影、影片解析、数理统计等方法对西安体育学院男子跳远运动员和国内外优秀选手助跑速度变化而影响起跳效果的因素进行比较研究。结果表明:跳远助跑各段落速度的变化对起跳效果及成绩产生很大影响;西安体育学院男子跳远运动员绝对速度低,起跳前两步速度、速度利用率呈下降趋势,影响起跳初速度;跳远起跳前一步的速度、速度利用率对提高起跳效果要比起跳前9—10m段的速度、速度利用率更具有实际意义。  相似文献

Managing Health Care in Oregon: The Search for a Civic Bioethics     

Sharon Bracci 《Journal of Applied Communication Research》2001,29(2):171-194

Managed health care deliberations in Oregon point to a "civic bioethics" model to resolve allocation issues through publicly articulated community values and priorities that influence legislative action. Communication practices in the Oregon experiment provide data to develop an evaluative framework to assess public moral deliberation in value-laden contexts such as health care distribution. The Oregon experience also points to dialogical virtues to heighten citizens' ethical sensibilities and political will, discursive tools to inform ethical communication practices in a civic bioethics model.  相似文献
