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

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

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

Policymakers and the public often turn to scientific experts for help in making decisions about complex policy problems. Such decisions, however, may involve trade‐offs among desired goals and so require considerable technical and political judgment. Typically there is no objectively "best" answer, although some answers may be better than others. We use a case study of a landfill siting process in Orange County, North Carolina, to analyze how quantitative scoring schemes may best be used to facilitate site selection processes. Quantitative scoring schemes, used and interpreted properly, can help policymakers and the public focus their attention on central rather than peripheral issues, and thereby conduct a more informed political debate. For the quantitative scoring scheme to fulfill this role, however, the community must be explicit about how the scoring scheme will be used within the larger decisionmaking framework. Clarifying the power and limitations of quantitative scoring schemes shows promise for facilitating decisionmaking regarding other locally unpopular land use siting processes, as well as any public policy decision involving multiple objectives. © 2000 by the Association for Public Policy Analysis and Management.  相似文献

National licensing examinations are typically large‐scale examinations taken early in a career or near the point of graduation, and, importantly, success is required to subsequently be able to practice. They are becoming increasingly popular as a method of quality assurance in the medical workforce, but debate about their contribution to patient safety and the improvement of healthcare outcomes continues. A systematic review of the national licensing examination literature demonstrates that there is disagreement between assessment experts about the strengths and challenges of licensing examinations. This is characterized by a trans‐Atlantic divide between the dominance of psychometric reliability assurance in North America and the wider interpretations of validity, to include consequences, in Europe. We conclude that the debate might benefit from refocusing to what a national licensing examination should assess: to achieve a balance between assessing a breadth of skills and the capacity for such skills in practice, and focusing less on reproducibility.  相似文献
