Around the time of the US decennial censuses, a renewed interest emerges in the method for apportioning the US House of Representatives. Various methods may show slight variations in illustrative apportionments, with biases favoring less populous states, but the general pattern remains. Definition of certain groups as included in the apportionment counts and coverage levels for selected groups have been debated in the judicial system, legal journals, and government. Unauthorized residents, and, sometimes, lawful immigrants, are often singled out for exclusion. The legal issues are complex, and illustrating the effects of these groups' inclusion is problematic due to poor measures, nationally and geographically. Using approximate distributions, these analyses suggest this next apportionment might differ slightly under various scenarios such as ones excluding either recently entered unauthorized residents or all unauthorized residents. Allowing for net authorized immigration greater than official estimates for the 1990s might have some effect for large states.  相似文献

WOMEN'S RISING MARKET OPPORTUNITIES AND INCREASED LABOR FORCE PARTICIPATION   总被引:1,自引:0,他引:1  
This paper examines the secular increase in the labor market activity of married women in the United States from 1975 to 1991. The research stresses two findings consistent with the hypothesis that married women increased their attachment to the labor force during this time period. First, increasing duration, not incidence, of married women's employment spells contributes the most to the increase in their rate of employment from 1975 to 1991. Second, the increase in married women's employment over the 1980s is largely due to their increased willingness to work more at any given wage, not their rising wage opportunities.

We built three simulation models that can assist rail transit planners and operators to evaluate high and low probability rail‐centered hazard events that could lead to serious consequences for rail‐centered networks and their surrounding regions. Our key objective is to provide these models to users who, through planning with these models, can prevent events or more effectively react to them. The first of the three models is an industrial systems simulation tool that closely replicates rail passenger traffic flows between New York Penn Station and Trenton, New Jersey. Second, we built and used a line source plume model to trace chemical plumes released by a slow‐moving freight train that could impact rail passengers, as well as people in surrounding areas. Third, we crafted an economic simulation model that estimates the regional economic consequences of a variety of rail‐related hazard events through the year 2020. Each model can work independently of the others. However, used together they help provide a coherent story about what could happen and set the stage for planning that should make rail‐centered transport systems more resistant and resilient to hazard events. We highlight the limitations and opportunities presented by using these models individually or in sequence.  相似文献

Evidence‐informed policy creates the conditions for families to perform the functions they provide for their members and society. To increase research utilization in policymaking, we must better understand policymakers and the professional and institutional cultures in which they operate. This exploratory cluster analysis examined within‐group differences in valuing, seeking, and use of social science research among 68 legislative staffers and 56 high‐ranking officials from 8 family‐serving executive agencies in Wisconsin. The findings are compared with a parallel study of 109 legislators from New York and Wisconsin. Among all 3 policy actors, a substantial proportion highly value research, actively seek it, and frequently use it in policy decisions; these Enthusiastic High Users of research are more attuned to political considerations compared to other clusters. Enthusiastic High Users in the legislative institution place a higher priority on innovative and action‐oriented research, whereas those in the agency institution prioritize the quality of research.  相似文献

This research examined whether maternal adult attachment predicted the coping suggestions mothers made to their children. A sample of 157 youth (M age = 12.42, SD = 1.20) and their maternal caregivers completed semi-structured interviews and questionnaires in a two-wave longitudinal study. Results revealed that maternal insecure attachment predicted fewer engagement coping suggestions (orienting toward stress) and heightened disengagement coping suggestions (avoiding or denying stress) both concurrently and over time. These associations were found after adjusting for other relevant characteristics of the child, mother, and family context. This study contributes to our understanding of the implications of adult attachment for parenting behavior, suggesting that insecure attachment undermines a parent's ability to provide adaptive coping guidance to their children.  相似文献
