This study uses data from an experimental employment program and instrumental variables (IV) estimation to examine the effects of maternal job loss on child classroom behavior. Random assignment to the treatment at one of three program sites is an exogenous predictor of employment patterns. Cross-site variation in treatment-control differences is used to identify the effects of employment levels and transitions. Under certain assumptions, this method controls for unobserved correlates of job loss and child well-being, as well as measurement error and simultaneity. IV estimates suggest that maternal job loss sharply increases problem behavior but has neutral effects on positive social behavior. Current employment programs concentrate primarily on job entry, but these findings point to the importance of promoting job stability for workers and their children. 相似文献

Identity is a critical developmental task during the transition to adulthood in Western societies. The purpose of the present study was to evaluate an empirically based, cluster-analytic identity status model, to examine whether all four of Marcia's identity statuses (diffusion, foreclosure, moratorium, and achievement) would emerge empirically, and to identify different patterns of identity formation among American college-attending emerging adults. An ethnically diverse sample of 9,034 emerging-adult students (73% female; mean age 19.73?years) from 30 U.S. universities completed measures of identity exploration (ruminative, in breadth, and in depth) and commitment (commitment making and identification with commitment), identity synthesis and confusion, positive and negative psychosocial functioning, and health-compromising behaviors. The identity status cluster solution that emerged provided an adequate fit to the data and included all four of Marcia's original identity statuses, along with Carefree Diffusion and Undifferentiated statuses. Results provided evidence for concurrent validity, construct validity, and practical applicability of these statuses. Implications for identity research are discussed. 相似文献

The Boren Amendment is frequently cited as an example where judicial involvement markedly shaped the implementation of federal legislation. Unlike other controversial health policies, Boren was eventually rescinded by Congress. Results indicate that the Amendment was repealed because changing socioeconomic, political, and programmatic conditions combined with policy‐oriented learning to facilitate a shift in policy venue away from the judiciary toward the President and Congress. This is because during the devolutionary climate of the mid‐to‐late 1990s, both the executive and legislature proved more conducive to the policy image promulgated by state officials that the Amendment unnecessarily restricted state discretion, than the policy image promulgated by providers that without the Amendment, low reimbursement levels would compromise access and quality. Data for this analysis derive from archival documents, secondary sources, and 101 interviews with state and federal experts. 相似文献

Whilst the British and Americans expended blood and treasure together in the Kuwaiti desert in 1991, bureaucratic blood from both sides was also visible on carpets in London and Washington. The reason was attempts to replace the access to Heathrow airport of two failing airlines, Pan American World Airways and Trans World Airlines, with American and United Airlines. This succession rights affair was one of the most difficult diplomatic negotiations ever on civil aviation between the United States and Britain. How and why that controversy developed, its resolution, and what impact on, and feedback from, the broader Anglo–American relationship that it had are the main concerns of this analysis. 相似文献

Purpose
How does prison gang membership affect recidivism? In this paper, we use a unique dataset of all releasees from prisons operated by the Illinois Department of Corrections during the month of November 2000, which includes demographic information and data on gang participation. We attempt to control for confounding factors that are traditionally associated with both prison gang membership and rearrest.Methods
We develop a potential-outcomes framework and describe the conditions under which a counterfactual can be estimated when gang membership is not randomly assigned. We combine regression analysis with Coarsened Exact Matching, which has several advantages over the more popular propensity score matching, to estimate the effect of gang membership on recidivism.Results
Prison gang membership results in a six percentage point increase in recidivism.Conclusions
Despite the strengths of the data, unobserved heterogeneity among inmates could still bias estimates. However, there are probably important subtleties to the gang participation decision such that experimental or quasi-experimental data are unlikely to increase our understanding of the relationship between gang-membership and post-release outcomes. We recommend incorporating ethnography with survey data collection, because ethnographers are able to document otherwise unobservable contextual information concerning the selection process which could be used to identify causal relationships. 相似文献897.

This article claims that the UN can be accused of encouraging ‐ rather than merely appeasing‐the ‘aggression’ and ‘ethnic cleansing’ that has occurred within the former Socialist Federal Republic of Yugoslavia and elsewhere. This is a conclusion that is based upon the UN's pronouncements on self‐determination which have led to both the creation of both a ‘right’ and/or ‘principle’ of self‐determination in international law and a widespread belief that it is legitimate to use armed force ‐ if not all means necessary ‐ to achieve this end. The article goes on to analyse the alternative actions that the UN could take in order either to limit or end its encouragement of these crimes. 相似文献

ABSTRACTMost scholars have not taken Cuban-American terrorism in the 1970s seriously, despite the unprecedented campaign of terror it unleashed. Borrowing a framework of self-identity usually applied to other terrorist groups and using case studies of the Cuban Nationalism Movement in New Jersey and of Alpha 66 in Florida, this article argues that Cuban-American political ideology was the key to its impact and its support from communities in Florida and New Jersey. Militant exiles saw themselves as betrayed by two enemy states, entitled to rule in their homeland, and imbued with a mission of civilizational renewal. In these ways, Cuban-American terrorists were similar to the Taliban in Afghanistan and their reign of terror in the 1970s should be appreciated as a major episode in the history of U.S. and global terrorism. 相似文献
