As welfare‐to‐work reforms increase women's labor market attachment, the lives of their young children are likely to change. This note draws on a random‐assignment experiment in Connecticut to ask whether mothers' rising employment levels and program participation are associated with changes in young children's early learning and cognitive growth. Children of mothers who entered Connecticut's Jobs First program, an initiative with strict 21‐month time limits and work incentives, displayed moderate advantages in their early learning, compared with those in a control group. A number of potential mechanisms for this effect are explored, including maternal employment and income, home environment, and child care. Mothers in the new welfare program are more likely to be employed, have higher income, are less likely to be married, have more children's books in their home, and take their children to libraries and museums more frequently. However, these effects explain little of the observed gain in child outcomes. Other parenting practices and the home's social environment do explain early learning, but these remained unaffected by welfare reform. © 2003 by the Association for Public Policy Analysis and Management 相似文献

Relatively little research has examined the effects of campaign-led field activity in a competitive election. In this article, we leverage a unique data set containing the location of every Barack Obama and Mitt Romney field office and county-level data on the presidential vote to understand how communication with voters in the field may have affected the outcome of the 2012 presidential election. We find that the presence of Obama field offices was associated with greater Obama vote share at the county level, although we cannot detect a similar relationship for Romney field offices. We conduct additional robustness tests to address the potential limitations of these observational data. Ultimately, we conclude that even if Obama’s field organization out-performed Romney’s, the aggregate impact of Obama’s field organization was not large enough to determine the outcome of the 2012 presidential election. 相似文献

Russia has been struggling to come to terms with the ethno-federalstructure it inherited from the USSR. Central and regional politicalactors have sought to restructure federal relations in a waythat marks a break from the pseudo-federalism of the past, andboth the 1992 Federation Treaty and the 1993 Constitution ofthe Russian Federation declared the establishment of a "federaldemocracy" This article investigates the process of refederalizationby examining debates over the idea of federalism in Russia.Despite an initial wide-ranging discussion, federalism is increasinglyseen in strategic terms by political elites. The federal systemis asymmetrical and bureaucratic, and it is based on a seriesof treaties between the center and constituent units, ratherthan on an effective constitution that binds the center andregions together. 相似文献
