In this paper we consider the abortion and E.R.A. issues as examples of single-issue politics, as well as the nature of single-issue politics in general. We argue that many single issues are what others have called easy issues but that hard-issue voting as well as easy-issue voting may be occurring on both issues. We test this hypothesis using both mass and elite data sets. Our findings suggest that political activists may be cuing the masses into a pattern of single-issue voting, and hence keeping the battle over abortion and the E.R.A. intense.An earlier version of this paper was presented at the 1981 Annual Meeting of the American Political Science Association, New York, September 3–6, 1981. 相似文献

Although relationships have been found between maternal psychological characteristics and cognitive and emotional outcomes in children, the behaviors which may mediate these relationships are seldom examined. This is especially true for adolescent mothers, whose children are thought to be at high risk for adverse outcomes. In this study, adolescent mothers in two special programs completed questionnaires measuring perception of the newborn (Neonatal Perception Inventory), knowledge of influences on child development (Infant Caregiving Inventory), and emotional state (General Health Questionnaire); they were also systematically observed while interacting with their infants in a naturalistic situation. Specific maternal behaviors were found to vary with the age of the mother and of the baby. Mothers with neutral or negative perceptions of their infants touched them less than did mothers with positive perceptions. Degree of emotional disturbance was inversely related to the amount of time that the mother looked at her infant while in physical contact.This research was supported in part by NIH Biomedical Research Support Grant No. BRS 507 RR 05445-19 to Johns Hopkins University School of Hygiene and Public Health.Received her Sc.D. in mental hygiene (comparative behavior) from Johns Hopkins University.

As part of a larger longitudinal study of psychosocial development, 148 girls and 130 boys were administered a series of questions regarding a close friend during their eighth-grade school year. Scales corresponding to shared experience, self-disclosure, and intimacy (defined as emotional closeness) were developed from these items. Path-analytic models tested the relative strength of the self-disclosure and shared experience paths to emotional closeness for boys and girls separately. The results indicated that the self-disclosure path to emotional closeness is significant for both boys and girls. No relationship was found between shared experience and emotional closeness in girls when controlling for self-disclosure. The relationship between shared experience and feelings of closeness was, however, significant for boys even while controlling for the effects of self-disclosure. Covariance structure analysis (LISREL) indicated that the covariance matrices for the three scales were significantly different for boys and girls. The results are considered in relation to the gender socialization and friendship literature. The potential importance of defining intimacy as emotional closeness is also discussed.The research reported here was supported by National Institute of Mental Health Grant MH30252/38142 to Anne C.

Objectives
Examine the distribution of various forms of violent victimization among adolescents in school and the main and interactive effects of low self-control and school efficacy on repeat assault victimization.Methods
This study used data collected from students and teachers as part of the Rural Substance abuse and Violence Project. We calculated a simple Poisson model of the expected frequencies of adolescents to experience each number of assault, robbery, and weapons victimizations given the total number of each type of victimization reported by the sample. We then tested whether the observed frequencies differed significantly from the expected. Finally, we estimated a series of hierarchical nonlinear models to assess the main and interactive effects of low self-control and school efficacy on repeat assault victimization.Results
All three forms of violent victimization were non-randomly distributed across students. Low self-control was associated with repeat victimization among assault victims, though this effect was weakened significantly by school efficacy.Conclusions
Violence in schools is highly concentrated among repeat victims. Efforts to reduce violence in schools should be focused on those who have already been victimized. Schools may be able to limit the effects of low self-control on repeat assault victimization by strengthening school efficacy.220.
Decentralizing Pork: Congressional Roll‐Call Voting,Decentralized Administration,and Distributive Politics 下载免费PDF全文
Congress packages pork‐barrel spending in complicated proposals that belie theories of distributive politics. We theorize that roll‐call voting on such bills depends on grant programs' administrative centralization, party ties with presidents or home‐state governors, and differences in geographic representation between chambers. Analyzing votes between 1973 and 2010 using a within‐legislator strategy reveals that House members are less likely to support decentralized spending when they are copartisans with presidents, while senators support decentralization regardless of such party ties. When House members or senators share affiliation with only governors or with neither chief executive, the likelihood of support rises with decentralization. 相似文献
