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

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   

奥斯本"企业家政府"理论的价值及应用     

彭照辉 《济宁师范专科学校学报》2004,25(2):103-105

“企业家政府”理论强调注重效率 ,提出了一系列切中时弊的主张 ,在行政改革中产生了较大影响。借鉴这一理论 ,政府内部管理应强调“结果为本”而不是“规则为本”,公共服务应以调控引导为主而不是直接提供 ,社会事务应放给社会自我管理而不是政府包揽 ,发展模式上应注重长远发展而不是一时增长。  相似文献

Developing the evidence base for UK film strategy: the research process at the UK Film Council     

David Steele 《Cultural Trends》2004,13(4):5-21

The UK Film Council established a Research and Statistics Unit in order to gather data relating to film to inform the development of UK Film Council strategy and to provide an information service to the industry, government, the arts and cultural sector and the wider research community. The Research and Statistics Unit draws data from both official and unofficial sources and commissions its own special-purpose studies to gather information relevant to the strategic objectives of the Council. Key tasks are the measurement of the size of the market for film and the various elements of the film value chain, the performance of films supported by the UK Film Council and the performance of UK films in general. Special-purpose research projects currently include a detailed survey of the film production workforce, a study of the economic impact of the UK screen industries and studies of the social impact of local cinemas and the experience of Black- and Minority-led film production companies. A range of industry and official partners are collaborating in these studies. The Research and Statistics Unit also provides statistical and policy analysis relating to the wider policy environment of UK film, including issues such as the future of film tax incentives. This analysis has been developed within the HM Treasury ‘Green Book’ framework with particular reference to understanding market failure in relation to film. Central to the market failure argument is the cultural value of film in both its qualitative and its quantitative aspects. UK Film Council research is placed in the context of the literature on hedonic pricing and contingent valuation. The industrial challenges of increasing cultural value are discussed. Finally, consideration is given to the potential of film to contribute directly to ‘public value’.  相似文献
