Increasing obesity among Americans is a serious issue in the US, especially in the pediatric and young adult population. We use a longitudinal design to examine the relationship between childhood poverty/welfare receipt and obesity onset and continuity from adolescence into young adulthood using three waves of the National Longitudinal Study of Adolescent Health. We include multiple measures of disadvantage that co-occur with poverty and model potential mediating mechanisms within a life course framework. We find a significant effect of poverty/welfare receipt in childhood on obesity outcomes for females, but not for males. However, other measures of socioeconomic disadvantage such as neighborhood poverty, and low parental education are related to obesity in both males and females. Poverty may impact female obesity through the mediating effects of physical activity, inadequate sleep, skipping breakfast and certain forms of parental monitoring, while race is an important confounder of poverty’s influence. This paper highlights the important influence of poverty and other aspects of social disadvantage on obesity outcomes during this critical transition to adulthood. Implications of this research include physical activity and parenting interventions for low-income youth. In addition, governmental efforts should be made to increase physical activity opportunities in poor neighborhoods.

We describe the DNA collection processes of an initial pilot and full study, which is designed to investigate joint peer and genetic effects on health behaviors and attitudes in a college campus setting. In the main study, 2664 (79.5%) students completed a Web survey and 2080 (78.7% of the survey completers after adjusting for the ineligible) provided a saliva DNA sample. The response rate for completing both the survey and the DNA portion of the study is 62.5%. Our DNA yields are of high quality. Overall, our experiences and results demonstrate that genetic data can be successfully collected as a part of traditional social science survey research projects. To aid others in doing so, we provide extensive details of our data collection experiences and offer recommendations to future researchers seeking to do or evaluate similar work.  相似文献

20世纪90年代,莫斯科的政治、经济和社会结构经历了重大变革,改变了莫斯科的国家地位和国际排名。本文研究莫斯科在俄罗斯国内和在欧洲城市中的地位。毫无疑问,莫斯科的发展特点是:在逐渐脱离国家城市体系的同时,也逐渐朝着国际方向发展。以经济指标来衡量,莫斯科在国内找不到竞争对手。它远远领先于国内其他城市,因为这些城市正快速融入国内和区域经济的潮流,只在很小的程度上参与经济全球化。相反,莫斯科越来越多地争取融入跨国公司和国际经济体系的行列。虽然莫斯科作为一个国际性城市的概念往往只是城市的政治工具,但事实上,如果俄罗斯的首都想要融入世界,其资本是有限的。从中欧的角度来看,目前莫斯科最重要的功能,是连结中欧、西欧和俄罗斯。但现实是,莫斯科与俄罗斯其他城市之间的差距将会继续扩大。  相似文献

This research examined whether maternal adult attachment predicted the coping suggestions mothers made to their children. A sample of 157 youth (M age = 12.42, SD = 1.20) and their maternal caregivers completed semi-structured interviews and questionnaires in a two-wave longitudinal study. Results revealed that maternal insecure attachment predicted fewer engagement coping suggestions (orienting toward stress) and heightened disengagement coping suggestions (avoiding or denying stress) both concurrently and over time. These associations were found after adjusting for other relevant characteristics of the child, mother, and family context. This study contributes to our understanding of the implications of adult attachment for parenting behavior, suggesting that insecure attachment undermines a parent's ability to provide adaptive coping guidance to their children.  相似文献

This article reviews published literature and provides an overview on present empirical evidence about the framing of price promotions. Concerning explicit price reductions (discounts, coupons, rebates), the effects of advertised reference prices and different frames of price discounts (relative versus absolute price discount, objective versus tensile price claims) on consumers’ reactions are discussed. Furthermore, the article examines empirical results on implicit price reductions (volume packs, free extra products) as well as on sale signs and restrictions (e.g. purchase limits, time limits) as popular ways of framing a deal. The key findings point out that framing a price promotion in different ways can affect consumers’ perceptions and evaluations of the deal. Based on the reviewed literature, the concluding section provides managerial implications and an agenda for further research.  相似文献

East European policy makers currently face critical trade-offs between economic imperatives and system legitimacy imperatives. Economic imperatives, derived from the goal of medium term prosperity, demand rapid privatization and marketization. System legitimacy imperatives demand measures to minimize the unemployment, wage cuts and income inequality resulting in the short term from privatization and marketization. In 1989–90 East Germany and Hungary appeared to face the least harsh trade-offs and to be best placed of the ex-communist countries to achieve successful system transformation. Unlike their East European neighbours, neither had to develop democratic and market institutions from scratch. East Germany would import the Federal Republic's political system and market institutions. Hungary already had organized political parties and had been developing market institutions since 1968. Using panel survey data, the paper shows that, despite considerable economic achievements since 1990, there is widespread personal dissatisfaction and distress, and the legitimacy of democratic and market institutions is weak. The main data sources are the Hungarian Socio-Economic Panel (1992–5777 individuals in 2888 households) and the East German segment of the German Socio-Economic Panel (1990–4453 individuals in 2179 households).  相似文献

The issue of transracial adoption has been a controversial issue in foster care and adoption placement decisions. In 1994, the 104th Congress passed the Multiethnic Placement Act (MEPA), forbidding agencies receiving federal funds from solely considering race, culture, and ethnicity in making foster care and adoption placement decisions. Congress mandated that the Department of Health and Human Services (DHHS) develop policy guidelines for child placement agencies to follow. In April 1995, DHHS issued the guidelines that agencies were to follow. The authors of the paper discuss the MEPA, DHHS's policy guidelines for agencies and the guidelines' legal support, and the implications for social work practice in foster care and adoption placements.  相似文献

Multiple discriminant analysis (MDA) is a frequently used statistical technique. Although the dependence of this technique on the underlying assumptions concerning population priors and misclassification costs is well known, the assumption most often made by researchers is that both population priors and misclassification costs are equal. The purpose of this paper is to demonstrate the magnitude of the effect of these assumptions on statistical results. In the savings and loan case used here, the population priors are known:however, the relative misclassification costs are not. To test the sensitivity of the results to the unknown misclassification costs several different misclassification cost assumptions are used.  相似文献
