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   

【新水令】曲牌风格流变探析     

王方好  阎方正 《保定学院学报》2020,(1):85-91

曲牌【新水令】由同名词牌演化而来,最初被运用在南戏《张协状元》之中,用于表达慷慨激越的感情风格。该曲牌具有较强的灵活性,从元代到清代,其题材不断被拓宽,感情色彩也不断发生变化,不再局限于慷慨激越的声情风格,表达的情感也更为丰富。分析梳理【新水令】这一曲牌在元明清三代的风格变化,可以对其有更为深入的了解,亦有助于对于曲史样式的研究。  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

赵富学 《武汉体育学院学报》2019,53(2):5-11

运用文献资料法、辩证分析法、逻辑推理法等研究方法，对习近平新时代体育强国思想的马克思唯物主义立场进行了演绎与阐释。研究认为：在马克思唯物主义立场层面，习近平新时代体育强国思想坚持体育强国梦与实现中华民族伟大复兴中国梦一脉相承的历史唯物主义立场和普遍联系的辩证唯物主义立场；坚持在体育强国建设进程中遵循问题导向的唯物主义本体论立场；坚持体育强国建设要利用好国际与国内两种资源的唯物主义内外因辩证关系的立场。在新的历史时期，习近平新时代体育强国思想引领着竞技体育、群众体育、体育产业等领域的发展理念和价值，创新与发展了马克思主义哲学的实践结构和理论视角，为开创新时代中国特色社会主义体育事业的新局面提供了坚实的理论基础和实践支持。  相似文献   

The effect of number of siblings and birth order on educational attainment: Empirical Evidence from Chinese General Social Survey     

《International Journal of Educational Development》2020

Data from China demonstrate that the effect of the number of siblings on education is restricted by many factors, such as children’s gender, urban or rural household registration, whether there is only one child, the birth order of children within the family, and parents’ status. Chinese families have significant preferences for the eldest son and the youngest son. Moreover, research based on the natural experiment and instrumental variable approach suggests that market-oriented reform of education has increased the cost of family education expenditures since China’s reform and opening up, which further aggravates the negative impact on education of having many siblings in an urban setting.  相似文献

王建民  丁斌 《南京体育学院学报(社会科学版)》2003,17(1)

采用文献资料与理论分析等方法 ,对中国男篮在第 2 7届奥运会和第 14届男篮世锦赛上攻、防技术资料进行分析研究 ,发现中国男篮整体实力确有提高 ,尤其是内线实力明显增强。但由于我国对篮球本质认识上的偏差 ,过分追求队员高度而忽视速度、战术与技术训练 ,特别是外线控球能力的培养 ,结果比赛时内、外线脱节 ,整体攻、防节奏慢 ,不仅内线实力难以发挥 ,相反丢失了过去快速、灵活的优势与特点。针对存在的问题 ,从主观认识、训练方法以及训练内容等方面提出了一些建议和改进措施。  相似文献
