Data from the Continuous Longitudinal Manpower Survey and the Current Population Survey were used to estimate the effects of CETA, a governmental jobs program, on the economic well-being of separated, divorced, and widowed women over age thirty. After training, CETA participants had increases in earnings and tended to have higher earnings than comparable CPS respondents. Participants in on-the-job training and public service employment had greater increases than participants in the other CETA programs. CETA enrollees with a high school degree had greater increases in earnings than those who had not completed high school, while whites had greater increases in earnings than non-whites. 相似文献

The policy sciences have advanced in the past by introspection, and there appears to be a need for a return to such self-conscious examination of the field of inquiry. A design orientation offers a useful framework for such an examination. It requires reconsideration of some of the fundamental premises of policy inquiry. This article explores what impact design might have on the conventional process framework and then proceeds to discuss the development of a design perspective. 相似文献

Past researchers have identified a range of psychosocial predictors of problem behaviors during adolescence, but have been less active in addressing this same issue in relation to the 18–25-year age group. The current study investigated risk and reckless behaviors in emerging adults using self-report measures and a cross-sectional design. Several of the major limitations associated with past research were overcome by sampling widely, making clear conceptual distinctions, avoiding confounds between predictors and criteria, developing more direct measures of key constructs, and controlling for demographic variables and for social desirability. In this sample of 375 emerging adults, risk behaviors were found to be reliably predicted by sensation seeking, but not by antisocial peer pressure, whereas the reverse pattern of association was more true in relation to reckless behaviors. Gender differences, especially in relation to the impact of social desirability considerations, are explored. 相似文献

Treaty federalism in North America encompasses not only governanceimplications of the historic treaties signed with Aboriginalpeoples, but also the modern-day treaties known as "comprehensiveland claim agreements." This article explores how treaty federalismis realized in Northern Canada through claims-mandated jointgovernment-Aboriginal boards dealing with wildlife management,land-use planning, and environmental protection. These boards,existing at the intersection of the three orders of government-national,federal/territorial, and Aboriginalare found to be uniquegovernance institutions, with substantial independence fromgovernment. They have significantly enhanced Aboriginal peoples'influence over land, wildlife, and resource decisions, but theextent to which they bring Aboriginal culture and worldviewsto bear in decision-making remains an open question. 相似文献

The level of degradation of DNA as a means for determining the time of death has been proposed as a valid adjunct to the classic thanatochronologic methods. The twofold aim of this work was to determine which organ might reveal both a correlation between the percentage of degradation of the DNA and the time lapse since death, and would be easiest to sample and yield the most reproducible results even in technically unfavorable situations such as on-the-spot investigations at the scene of death. A comparison of the spleen, blood, and liver showed that hepatic tissue best meets these specific needs because it shows a virtually linear correlation between the time elapsed since death and the level of degradation of the DNA, and it can easily be sampled at the scene of death by use of a common biopsy needle. 相似文献
