Over the years, many suggestions have been made on how to reduce the importance of family background in political recruitment. In this study, we examine the effectiveness of one such proposal: the expansion of mass education. We utilize a difference‐in‐difference strategy to analyze how a large school reform launched in Sweden in the 1950s, which lengthened schooling and postponed tracking, affected the likelihood of individuals with different family backgrounds to run for public office. The data come from public registers and pertain to the entire Swedish population born between 1943 and 1955. The empirical analysis provides strong support for the view that improved educational opportunities for individuals from disadvantaged backgrounds can be an effective means to reduce the social bias of elected assemblies. 相似文献

Quantitative analysis by quadrupole mass fragmentography is a rapid and accurate method for assay. Its advantage is fundamentally the requirement for very small sample sizes. One must allude to the disadvantage of these techniques in the preparation of a deuterated internal standard (if not commercially available) and operator experience with sophisticated instrumentation. By extrapolating the signal intensities to the baseline intersection (no response) assuming optimal gas chromatographic conditions, 0.5 ng of heroin injected on column appears to be the limit of detection by the above-referenced equipment. 相似文献

Current proposals for strengthening policy ownership in reforming economies are fundamentally flawed. Modeling the reform
process as a prisoners’ dilemma demonstrates that political agents must overcome this conflict of interests before present proposals for bolstering ownership will work. A politically autonomous mass media is one important mechanism enabling
political agents to do this. Reforming countries without free media face an uphill battle overcoming the problems associated
with transition. We test our theory by investigating the relationship between media freedom, foreign aid, and economic development
in 26 post-socialist transition countries. The results of this analysis support our theory.

The use of actuarial risk/need assessment tools is an increasingly important part of the correctional landscape. Actuarial tools ideally will provide a valid, dynamic assessment of an offender's overall risk/need level, and will identify their most prevalent criminogenic needs. What results is typically a number or score that can be used to assign an offender to a risk level that is associated with an assumed likelihood of recidivism. Testing the predictive validity of actuarial risk/need assessment tools is of paramount concern, particularly when they are utilized with new (and under-researched) populations. The current study assessed the predictive validity of the Level of Service Inventory-Revised using a sample of Native American and White offenders in a northern midwestern state. Results showed the instrument to have modest predictive validity utilizing the entire sample of offenders, with varying results for subsequent subgroups. 相似文献
