We present strong evidence that governing coalitions in Italy exercise significant negative agenda powers. First, governing parties have a roll rate that is nearly 0, and their roll rate is lower than opposition parties' roll rates, which average about 20% on all final‐passage votes. Second, after one controls for distance from the floor median, opposition parties have higher roll rates than government parties. These results strongly suggest that governing parties in Italy are able to control the legislative agenda to their benefit. We also document significantly higher opposition roll rates on decree‐conversion bills and budget bills than on ordinary bills—results consistent with our theoretical analysis of the differing procedures used in each case.  相似文献

Research Summary: This study examines self-reports from two samples to assess the timing of delinquency. Results imply that the after-school hours are a time of elevated delinquency, but that the peak is modest compared with that observed in official records. Additionally, children who are unsupervised during the after-school hours - the primary target population for after-school programs - are found to be more delinquent at all times, not only after-school. Policy Implications: This finding suggests that factors (including social competencies and social bonding) in addition to inadequate supervision produce delinquency during the after-school hours and that the effectiveness of after-school programs for reducing delinquency will depend upon their ability to address these other factors through appropriate and high quality services.  相似文献

Despite the substantial body of research on the psychological and social effects of racial segregation in schools on African Americans, few studies have considered the possibility that more racially inclusive schools might reduce the risk of extremely negative adult life experiences such as incarceration. Yet such a connection is made plausible by research linking black racial isolation in schools to variables that are often associated with incarceration rates, including concentrated poverty, and low educational and occupational aspirations and attainment. In this paper, we apply methods first developed by labor economists to assess the impact of racial inclusiveness in schools on individual incarceration rates for 5‐year cohorts of African Americans and whites born since 1930. We find strong support for the conclusion that blacks educated in states where a higher proportion of their classmates were white experienced significantly lower incarceration rates as adults. Moreover, our analysis suggests that the effects of racial inclusiveness on black incarceration rates have grown stronger over time. These longitudinal effects are consistent with the argument that the educational climate of predominantly black schools has deteriorated in more recent decades.  相似文献
