Political parties maintain local organisations and recruit members mainly to fight elections. For most of the post-war period, however, the dominant view among analysts has been that constituency campaigning in British general elections has little or no effect on election outcomes. This view has been challenged over the last ten years or so. Evidence derived from post-election surveys of constituency election agents following the 1992, 1997 and 2001 general elections is used here to show that the intensity of constituency campaigning significantly affects turnout levels and, for Labour and the Liberal Democrats, levels of party support. There is also some evidence that Conservative campaigning affected constituency variations in the party's performance in 2001. The conclusions reached on the basis of aggregate-level analysis are supported by analysis of individual-level data derived from British Election Study surveys. The effects of campaigning are not large, but they are clear and significant – and sufficient to affect the numbers of seats won by the major parties. In the light of this, parties have good reasons to maintain healthy local organisations.  相似文献

Elections for the Scottish Parliament and for all Scottish local authorities were held on the same day in 1999 and 2003, allowing a more detailed exploration of turnout variations than has been possible before. On both occasions, turnout in the two sets of elections was almost identical so that reported ward turnout at local level also indicates ward turnout in the parliament elections. Parliamentary turnout is analysed at both constituency and ward levels. The latter gives us greater confidence in the constituency results and also suggests some relationships which are not apparent at constituency level. The strongest determinant of turnout is consistently found to be the proportion of adults with a degree; religious affiliation, here analysed for the first time at the aggregate level, is also strongly related to turnout.  相似文献

Corporal punishment is a controversial practice used by the majority of American parents and is especially prevalent among African Americans. Research regarding its consequences has produced mixed results although it is clear that there is a need for considering the context within which corporal punishment is administered. To assess the impact of spanking, we employed an expanded parenting typology that includes corporal punishment. Longitudinal self-report data from a sample of 683 African American youth (54 % female) were utilized to evaluate the relative impact of the resulting eight parenting styles on three outcomes: conduct problems, depressive symptoms, and school engagement. Results from Negative Binomial Regression Models indicate that the effect of corporal punishment depends upon the constellation of parenting behaviors within which it is embedded and upon the type of outcome being considered. While it is never the case that there is any added benefit of adding corporal punishment, it is also the case that using corporal punishment is not always associated with poor outcomes. Overall, however, our findings show that parenting styles that include corporal punishment do not produce outcomes as positive as those associated with authoritative parenting.  相似文献

Despite the declining rate of teen pregnancies in the United States, academic and public health experts have expressed concern over the still relatively high rate of rapid repeat pregnancies among adolescents, particularly among minority youth. Using a sample of over 300 African American female adolescents, the current study used insights from the prototype/willingness model of adolescent risk behavior to explore this risk. More specifically, it assessed the relationship between entry into unwed motherhood during mid-to-late adolescence and changes in prototypes of unmarried pregnant teens. Further, it explored the extent to which these changing prototypes accounted for young mothers’ later contraceptive expectations. We tested the possibility that social images were affected not only by personal experience (the birth of a child) but also by the family and community context in which this experience took place. The findings show that the early entrance into teen motherhood was associated with a shift toward more favorable prototypes of unwed pregnant teens, but that this was only the case for young mothers in disadvantaged contexts. Given this, prototype changes helped to explain the link between teen motherhood and contraceptive expectations only for those in disadvantaged contexts. We discuss these findings in terms of their practical and theoretical implications.  相似文献

Previous research has documented that adverse life experiences during adolescence, particularly for ethnic minorities, have a long-term influence on income and asset attainment and that this relationship is largely mediated by educational achievement. We extend prior research by investigating three research questions. First, we investigate the extent to which community disadvantage, family factors and race/ethnicity each exert an independent influence on young adult socioeconomic attainment. Second, we examine whether youths’ educational attainment mediates these independent influences on socioeconomic attainment. Third, we test whether educational attainment ameliorates the negative influences of disadvantaged community and family conditions and race/ethnicity on socioeconomic attainment. We address these questions using multilevel modeling with longitudinal, prospective data from Waves 1 and 4 of National Longitudinal Study of Adolescent Health, which has a nationally representative sample of adolescents (N?=?13, 450; 53?% females). Regarding our first research question, our results indicated that African Americans, youth from disadvantaged communities, lower SES families achieve significantly lower levels of earnings, assets, and job quality during young adulthood. Second, we found that young adults’ educational level only partially mediate the influences of family and race/ethnicity influences on young adults’ socioeconomic attainment. Third, we found that young adults’ educational level buffered the influence of early socioeconomic adversities and accentuated the positive influences of family resources. Findings highlight the importance of social context as well as educational opportunities during childhood and adolescence for economic stability in early adulthood.  相似文献

Nonprofit child care centers are frequently observed to produce child care which is, on average, of higher quality than care provided in commercial child care centers. In part, this nonprofit advantage is due to different input choices made by nonprofit centers—lower child‐staff ratios, better‐educated staff and directors, higher rates of professional development for staff. Nonprofit centers may have an additional productivity advantage, due to unmeasured staff motivation and abilities or to better management of the production of good‐quality child care. However, where nonprofit and for‐profit child care firms compete in the same local markets, we speculate that this extra advantage should only appear where demand is sufficiently “thick” to permit a quality differentiation strategy to be financially viable for nonprofits. We estimate the effect of nonprofit status on quality, controlling for differences in financial resources available to the center, differences in the clientele served, and differences in staff and center inputs. In this conventional examination, nonprofit status has a moderately positive impact on quality. However, when we account for the unobserved heterogeneity and separate markets into “thick” and “thin,” a particularly strong nonprofit advantage is found in thick markets, but no productivity advantage for nonprofits is found in thin markets. This finding suggests a clear role for nonprofit organizations in improving the cost‐quality trade‐off faced by parents, but also identifies the market conditions that affect the ability of nonprofit managers to employ this advantage. © 2009 by the Association for Public Policy Analysis and Management.  相似文献
