Pre‐college advising programs exist in most disadvantaged high schools throughout the United States. These programs supplement traditional advising by high school guidance counselors and attempt to help underrepresented and disadvantaged students overcome the complexities of the postsecondary admission and financial aid processes. Existing evidence on these programs often uses within‐school randomization where spillovers and alternative supports may confound estimates. We provide the first evidence on a whole school intervention resulting from a school‐level randomized controlled trial in the United States. The college access program we study uses a near‐peer model where a recent college graduate works at the school assisting students in the application and enrollment process. Pooled results across the first three years of program implementation find no significant impacts on overall college enrollment. However, subgroup analyses reveal positive, significant effects among the groups most targeted by the intervention: Hispanic and low‐income students. Most of the impact comes through increasing two‐year college enrollment, but this appears to be new entrants rather than inducing students to move from four‐year to two‐year colleges. The observed positive effects for these subgroups attenuate over time. We attribute this drop in the estimated impact to departures in fidelity of the experiment. Even among the cohorts for which we find positive enrollment impacts, we find no significant impacts on college persistence. 相似文献

Low population density in rural developing countries coupled with deficient infrastructure, weak state capacity and limited budgets makes increasing health care coverage difficult. Contracting-out mobile medical teams may be a helpful solution in this context. This article examines the impact of a large-scale programme of this type in Guatemala. We document large impacts on immunisation rates for children and prenatal care provider choices. The programme increased substantially the role of physician and nurses at the expense of traditional midwives. The results indicate that mobile medical teams substantially increased coverage of health care services in Guatemala, and could be effective in other developing countries. 相似文献

The pattern of Asian geopolitics can be examined by employing three analytical perspectives. The first employs East Asia and the vigorous debate over the meaning of the rise of China as an intellectual prism to observe the currents of geopolitical continuity and change that are currently abroad in the Asian region. The second explores the extent to which the interacting forces of geopolitics and military modernization foster the rise of new force projection capabilities that may affect the strategic environment in Asia—particularly in East Asia. Here, the focus is mainly on the arsenals of the three indigenous Asian giants, China, Japan and India, all of whom have developed, or are in the process of developing, significant air and maritime assets whose operations have the potential to intersect in East and South East Asia. Russia is not as much a presence because it no longer possesses its powerful Soviet-era Pacific Fleet and has, in essential respects, retreated to its traditional role as a Eurasian land power.1 The third examines the future of Sino-American relations in Asia in the context of the debate over China's ascent and U. S. decline—a discussion that has intensified since the implosion of the U.S. financial system in 2008 and the onset of the worst global recession since the 1930s. 相似文献
