Sociometric nominations, social cognitive maps, and self-report questionnaires were completed in consecutive years by 327
students (56% girls) followed longitudinally from grade 7 to grade 8 to examine the stability of social standing in peer groups
and correlates of changes in social standing. Social preference, perceived popularity, network centrality, and leadership
were moderately stable from grade 7 to grade 8. Alcohol use and relational aggression in grade 7 predicted changes in social
preference and centrality, respectively, between grade 7 and grade 8, but these effects were moderated by gender and ethnicity.
Changes in social standing from grade 7 to grade 8 were unrelated to grade 8 physical aggression, relational aggression, and
alcohol use after controlling for the grade 7 corollaries of these behaviors. Results are discussed in terms of their implications
for understanding links between social standing and problem behaviors during adolescence.

Responding to recent articles in Governance highlighting the need for improved measurement of bureaucratic characteristics, this article describes efforts to map Brazil's federal agencies on three dimensions—capacity, autonomy, and partisan dominance—derived from data on more than 326,000 civil servants. The article provides a “proof of concept” about the utility of agency‐level measures of these variables, demonstrating how they relate to an output common to all agencies: corruption. The article provides a first step in the direction of building a comparative research program that offers objective evaluation of bureaucracies within nation‐states, with the intent of better disentangling their impact on governance outcomes. 相似文献

The mismatch between the housing needs of persons with a disability and the housing programs designed to accommodate those needs is an important housing policy concern. The U.S. Department of Housing and Urban Development (HUD) sponsors several programs designed to improve the housing conditions of persons with a disability, but we know little about the characteristics of persons with a disability, among those receiving federal housing assistance, or the degree to which persons with a disability are served by HUD-sponsored housing programs that are designed to meet the needs of persons with a disability. Our study relies on administrative data from HUD and the U.S. Census Bureau to address this research gap. We find that many persons with a disability are served by HUD-sponsored programs that are not designated for persons with a disability, even when disability accommodations have been requested, and a similarly large share of persons with a disability live in potentially eligible low-income households that do not receive HUD assistance. 相似文献
