The goals of this study were to test the relationship between dating violence victimization (i.e., verbal, emotional, and physical abuse) and psychological well-being (i.e., depressive symptomatology, self-esteem, and body image) among 522 African American girls, and to determine whether social support acted as a buffer of negative effects (moderator) or as an intervening factor (mediator) in the relationship between dating violence victimization and psychological well-being. Results from structural equation modeling indicated that dating violence victimization was associated with negative psychological outcomes. Although social support did not moderate this relationship, it served as a mediator of the relationship between dating violence victimization and psychological well-being. Dating violence programs for African American girls should consider how to incorporate family, church, and other networks in the community to foster support, and allow adolescent girls to discuss their abusive experiences in a nonblaming environment. If programs are able to buoy girls who experience dating violence, then they may be able to ameliorate the associated negative psychological sequelae.  相似文献

Drawing on models of health self-management, we develop hypotheses that age and ethnicity will modify associations among indicators ofpoor health and use of complementary and alternative medicine. These hypotheses are evaluated using the 2002 National Health Interview Survey with the Alternative Health Supplement. Results produced partial support for hypotheses that the effects of ailments on use of complementary and alternative medicine differ by age. Results suggest that ailments such as bodily pain, chronic conditions, and functional impairment are associated with use of complementary and alternative medicine among midlife and younger adults, but these associations are generally attenuated among older adults. Hypothesized ethnic differences received weak support. These findings suggest that different interpretations of ailments and appropriate responses may explain why complementary and alternative medicine is used by fewer older adults. The results also highlight the significance of social and cultural factors in understanding patterns of complementary and alternative medicine use in the adult population.  相似文献

Many different models for the analysis of high-dimensional survival data have been developed over the past years. While some of the models and implementations come with an internal parameter tuning automatism, others require the user to accurately adjust defaults, which often feels like a guessing game. Exhaustively trying out all model and parameter combinations will quickly become tedious or infeasible in computationally intensive settings, even if parallelization is employed. Therefore, we propose to use modern algorithm configuration techniques, e.g. iterated F-racing, to efficiently move through the model hypothesis space and to simultaneously configure algorithm classes and their respective hyperparameters. In our application we study four lung cancer microarray data sets. For these we configure a predictor based on five survival analysis algorithms in combination with eight feature selection filters. We parallelize the optimization and all comparison experiments with the BatchJobs and BatchExperiments R packages.  相似文献

这是一篇基于一个个案研究而企图探讨改革开放以来中国乡村政治的变迁的论文.通过个案,要讨论的是这样一些问题:从20世纪70年代末实施改革开放以来,中国的村庄政治尤其是村庄权力结构及运作经历了怎样的变化?这些变化到底意味着什么?由此,在某种程度上揭示出中国农村的政治运行逻辑.基本的发现是:七一村(个案村)的权力结构存在一个核心权力层,但已经出现多样性的格局,是一个多样性的一元结构,有变的一面,也有不变的一面;通过研究发现七一村的村庄政治属于发展型的权威主义,并且有着父爱主义的色彩;无论从规章制度文本、会议制度还是决策机制,七一村权力运作的规范性程度有了很大的提升,形成了能人政治、精英治理.这将是中国经济相对发达村庄的一个长期的模式.七一村虽然只是一个普普通通的村庄,但20世纪中国的大变迁却使小小的村庄伴随着我们这个国家经历了此前未曾经历的变化.通过七一村的个案研究可为中国农村内部秩序重建提供学理的根据与对策建议.  相似文献

15-17世纪,西方大学有了长足的发展,耶稣会高等学校遍及意大利、法国、西班牙、葡萄牙等国家和地区,成为当时欧洲最大的高等教育机构.以耶稣会高等学校"西学六科"为基础的大学学科体系,反映了这一时期西方高等教育在学科及课程设置方面的基本特征.在明清之际"西学东渐"的过程中,伴随着"西学六科"的导入,西方大学学科体系传入中国,对明清学术和思想产生了不容忽视的影响,也成为西方高等教育传入中国的滥觞.  相似文献

由美国次贷危机引发的欧美金融危机,对世界经济产生了巨大的影响.花卉产业作为世界农业中唯一不受农产品配额限制的产业,在此次金融危机中也受到了冲击.通过研究近两年我国鲜切花的进出口贸易基本情况,发现金融危机影响了我国鲜切花的进出口贸易数额和贸易结构,进而波及到国内花卉企业的经营发展.因此,应该增加进口,吸引投资;打造品牌,把关质量;适当引导,扩大内需,以促进国内花卉业的发展壮大.  相似文献

In HIV vaccine studies, longitudinal immune response biomarker data are often left-censored due to lower limits of quantification of the employed immunological assays. The censoring information is important for predicting HIV infection, the failure event of interest. We propose two approaches to addressing left censoring in longitudinal data: one that makes no distributional assumptions for the censored data—treating left censored values as a “point mass” subgroup—and the other makes a distributional assumption for a subset of the censored data but not for the remaining subset. We develop these two approaches to handling censoring for joint modelling of longitudinal and survival data via a Cox proportional hazards model fit by h-likelihood. We evaluate the new methods via simulation and analyze an HIV vaccine trial data set, finding that longitudinal characteristics of the immune response biomarkers are highly associated with the risk of HIV infection.

Multiperiod models of criminal enforcement based on the standard economic approach of Becker (1968) generally find that the optimal penalty structure is either flat or declining. We present the first experimental test of a two‐stage theoretical model that predicts decreasing penalty structures will yield greater deterrence than increasing penalty structures. This prediction is based on the belief that if the penalty for the first offenses is sufficiently low, the agent should commit the offense and continue to offend if undetected. Our results are consistent with the theoretical prediction that decreasing fine structures are more effective at reducing risky behavior. (JEL C91, K42, K10)  相似文献
