This study addresses two limitations of coparenting research: first, little research on coparenting has been conducted with families of adolescents, and second, there is little understanding regarding the child and family contexts in which coparenting is most salient. The longitudinal relation of coparenting conflict to parenting and adolescent maladjustment across 3 years was investigated among 516 2-parent, 2-adolescent families. Coparenting conflict predicted as much or more unique variance in parenting and adolescent adjustment as did marital quality and disagreement together. After controlling for stability, coparenting conflict predicted mothers' and fathers' negativity and adolescent antisocial behavior (but not depression). Importantly, the influence of coparenting conflict in all cases varied as a function of family type, adolescent gender, or initial level of antisocial behavior, or all. The implications of these results for family processes in different relational and developmental contexts are discussed. 相似文献

We develop a framework that makes it possible to study, for the first time, the strategic interaction between the ex ante choice of exchange‐rate regime and the likelihood of ex post currency attacks. The optimal regime is determined by a policymaker who trades off the loss from nominal exchange‐rate uncertainty against the cost of adopting a given regime. This cost increases, in turn, with the fraction of speculators who attack the local currency. Searching for the optimal regime within the class of exchange‐rate bands, we show that the optimal regime can be either a peg (a zero‐width band), a free float (an infinite‐width band), or a nondegenerate band of finite width. We study the effect of several factors on the optimal regime and on the probability of currency attacks. In particular, we show that a Tobin tax induces policymakers to set less flexible regimes. In our model, this generates an increase in the probability of currency attacks. (JEL: F31, D84) 相似文献

Since 1989 nearly one million immigrants from the FSU have arrived in Israel. Although well‐educated on average, most of these immigrants lacked economic means. The purpose of the present study is to examine whether the presence of immigrants in schools affected the educational achievements of their Israeli‐born peers. We analyzed data pertaining to 8,288 Israeli tenth graders who attended 208 schools in 1994. Respondents' records were obtained from the Ministry of Education and the Bureau of the Census. Using hierarchical models we examined the effects of the proportion of immigrant students in a school and of their parents' education on the probability that Israeli‐born students in the school would earn matriculation certificates. Results did not yield evidence of any negative spillover effects on the educational achievements of the native students. Moreover, the presence of many immigrant students with high educational backgrounds increased the likelihood of Israeli‐born students earning matriculation certificates. 相似文献

This study used longitudinal survey and social network data covering sixth through ninth grades to test whether internalizing symptoms make early adolescents more prone to (1) exposure to and (2) influence by substance‐using peers. Random effects regressions revealed that increases in symptoms were significantly associated with increases in the proportion of friends who used cigarettes, alcohol, and marijuana; some associations weakened across grades. Event history models revealed that the effect of friends' smoking on smoking initiation decreased as internalizing symptoms increased; symptoms did not moderate the effects of friends' alcohol and marijuana use on alcohol and marijuana use initiation. These findings counter the influence hypothesis of the co‐occurrence of internalizing symptoms with substance use and partly support the exposure hypothesis. 相似文献

Abstract The association of knowledge of health risks, living arrangements, and perceived stress with health-risk behaviors was examined in a sample of college students included in the Health Promotion and Disease Prevention Supplement of the National Health Interview Survey. Regressions of each health-risk behavior (dependent variable) were performed on the predicted correlates. Although knowledge was not associated with participation in physical activity or smoking, the study found that students who knew more about the harmful effects of alcohol drank less, and those with greater knowledge of health risks practiced fewer risky behaviors. Students living independently were more likely to smoke, and those living in residence halls were less like to do so. Drinking, however, was more common among students living in residence halls or independently than among those living at home. Hall residents engaged in more group physical activity than other students did, but their physical activity was unrelated to health-risk behaviors. Stress was associated with smoking but not with other health practices. The findings suggest that smoking may be less influenced by health knowledge and more associated than drinking is with a response to stress. Drinking appears to be a social activity associated with living among peers and is potentially modifiable by increased knowledge about the effects of alcohol on health. 相似文献
