Latvian higher education has undergone a dramatic transition since 1991. This study employs a survey of nearly 1000 social science students studying in 13 different institutions in Latvia to consider the impact of the increase in the number of students who are working while studying. Evidence indicates employment has a strong and significant negative impact on school performance, and the negative impact increases as weekly hours worked increase. This manifests itself through reduced class attendance and reduced time spent in independent study. Finally, we find that the probability of student employment is most significantly affected by the availability of financial aid, gender, ethnicity, and age.  相似文献

What Do Prosecutors Maximize? Evidence from the Careers of U.S. Attorneys   总被引:1,自引:0,他引:1  
This study examines the performance of chief federal prosecutors(U.S. attorneys) and their subsequent careers. In a sample of570 attorneys in office from 1969 to 2000, the length of prisonsentences is positively related to subsequent favorable careeroutcomes for U.S. attorneys. In contrast, conviction rates donot appear to affect the careers of U.S. attorneys. These resultsare consistent with longer total prison sentences’ beingpersonally beneficial to prosecutors, and prosecutors’maximizing the length of prison sentences. Overall, the resultssuggest that sentence length, as opposed to convictions rates,is the relevant performance metric.  相似文献

In the public debate over incarceration policy, there is considerable disagreement about what value of individual offending frequency (λ) is appropriate to use in estimating incapacitative effects. This article provides an approach for estimating the mean values of λ for diverse subsets of the total offender population, with particular emphasis on subsets generated by filtering through various stages of the criminal justice system. Sharp differences in offending frequency are displayed between robbery and burglary inmates, across three states, and particularly between resident inmates and free, active offenders. Free offenders average 1 to 3 robberies and 2 to 4 burglaries per year, while resident inmates have λ values 10 to 50 times higher. Differences result from the underlying levels of criminal activity and the sanction Levels that offenders face. A highly heterogeneous distribution of offending frequency in the total population of offenders combines with relatively Low imprisonment levels to lead to substantial selectivity of high-λ offenders among resident inmates and a correspondingly low mean value of λ among those offenders who remain free. These results have important implications for estimating incapacitative effects of an increase in incarceration, since the additional inmates will be drawn from free offenders whose mean λ is at least an order of magnitude Lower than that of the current inmate population.  相似文献
