Some rural regions of Peru showed remarkable rates of poverty reduction and inequality reduction between 2004 and 2012, while others lagged behind. Using microsimulation-based decompositions, we analyse the driving forces behind these trends, finding that rural poverty and inequality reductions are mainly attributable to increasing labour incomes in Peru’s agricultural sector and, to a smaller extent, increasing public transfers. In earlier years, higher returns to experience drive these results, while in later years, increasing staple-crop yields and prices are of key importance. Further, remuneration of working hours increases in reaction to labour-supply shortages in rural areas. The accompanying rising incomes and non-agricultural job creation is less pro-poor than would be ideal, as they benefit more highly skilled workers. Further, shrinking farm sizes hampers poverty reduction and income-inequality reduction. Policies should target the participation of the poor in high-value (non-)agricultural activities, especially if positive trends in commodity prices are only transitory. 相似文献

The probability of selecting the ath best out of n applicants in the secretary problem is evaluated by probabilistic arguments for monotone order k stopping rules. This leads to an explicit optimizing function for selecting (with payoffs) one of the k best applicants. This optimization problem can be solved directly both for a finite and for an unlimited number of applicants, yielding a variety of numerical results. Extensions are given for two choices with success if two applicants are selected from among the k best. 相似文献

Objective. Although political scientists studying the role of schools on political socialization have focused most of their efforts on curriculum, mainly civic education, education scholars have long recognized that schools influence outcomes through much more than curriculum and have examined school organization extensively, including school size. Much of the recent literature on school size supports smaller schools. The objective of this article is to examine the effect of school size on two political socialization outcomes: adolescent participation in school activities and volunteering. These outcomes are important because they are related to later adult participation. Method. A nationwide survey is used to conduct regression analyses as the primary method. Results. The results show limited support for smaller schools, even for those groups who are believed to benefit most significantly from small schools: racial minorities, low‐income students, and underachievers. Conclusion. I conclude with an appeal for caution among education reformers seeking to downsize schools and a recommendation to political socialization scholars to expand their analyses beyond civic education curriculum. 相似文献

In this study, we explore academic procrastination and associated motivation variables in 612 adolescents from Canada and Singapore. Few studies have explored adolescent procrastination and no previous studies have investigated adolescent procrastination using a cross‐cultural framework. Singaporean adolescents reported higher levels of procrastination and lower levels of self‐efficacy for self‐regulation than Canadian adolescents. Males across settings reported higher levels of procrastination and lower levels of self‐efficacy for self‐regulation than females. Bivariate relationships between procrastination and the motivation variables showed similar patterns in Singapore and Canada. Multigroup structural equation modeling revealed that self‐efficacy for self‐regulation showed the strongest multivariate relationship with procrastination for adolescents in both settings. The article concludes with implications for practitioners and researchers. 相似文献

This article explores changing growth regimes in Uganda, from pro‐poor growth in the 1990s to growth without poverty reduction, actually even with a slight increase in poverty, after 2000. Not surprisingly, it finds that good agricultural performance is the key determinant of direct pro‐poor growth in the 1990s, while lower agricultural growth is the root cause of the recent increase in poverty. At the same time, after 2000 low agricultural growth appears to have induced important employment shifts out of agriculture, which have dampened the increase in poverty. The article also assesses the indirect form of pro‐poor growth by analysing the incidence of public spending and the tax system, and finds that indirect pro‐poor growth has been achieved to only a limited extent. 相似文献

Abstract In recent years the phenomenon of young black grand-motherhood is attracting the attention of social scientists in many disciplines. This problem stems from the fact that young unmarried teenage girls are giving birth and are thus making their young mothers grandmothers. The complexity of the problem mounts owing to the fact that many young grandmothers have not completed their own developmental tasks. This paper addresses some of the issues involved and provides strategies for social work intervention. 相似文献
