Engagement in school is crucial for academic success and school completion. Surprisingly little research has focused on the relationship between student engagement and delinquency. This study examines whether engagement predicts subsequent school and general misconduct among 4,890 inner-city Chicago elementary school students (mean age: 11 years and 4 months; 43.3% boys; 66.5% black; 28.8% Latino). To improve upon prior research in this area, we distinguish three types of engagement (emotional, behavioral, and cognitive), examine whether the relationship between engagement and misconduct is bidirectional (misconduct also impairs engagement), and control for possible common causes of low engagement and misconduct, including peer and family relationships and relatively stable indicators of risk-proneness. Emotional and behavioral engagement predict decreases in school and general delinquency. However, cognitive engagement is associated with increases in these outcomes. School and general delinquency predict decreased engagement only in the cognitive domain. Suggestions for future research and implications for policy are discussed.  相似文献

Courts of modern democratic societies have generally implemented appeal procedures to correct potential errors in ruling. However, considering the time and effort that both litigants spend, availability of an appeal cannot be better than reaching the correct judgment in the original case. This difficulty raises the policy issue of how to reduce the rate of appeals and improve welfare of litigants. In this paper, we assert that lower caseloads allow judges to expend more time and effort on each case, contributing to lower appeal rates. Analysis of court-level data from Korea corroborates our inference.  相似文献

<正>The"Four Comprehensives"may constitute the main pillars for the next phase of the Chinese social and economic transformation.The general direction of these principles is,however,not new.It has been widely recognized that China needs ongoing reforms for more sustainable and socially inclusive growth.Otherwise,imbalances will increase,posing higher risks to the Chinese and world economy.Being principles,they are rather vague and leave much room for interpretation and adjustment.Concrete targets on the social and economic transformation have not been set.The need for reforms is urgent in many areas,and it is a challenging task to keep the balance.Development priorities Future GDP growth should become more sustainable and should not harm the environment.Eco-friendly growth can be supported if the service sector accounts for a higher share of the economy.The service sector is also less productive on average,implying that high employment can be realized even at  相似文献
