利用中国健康与营养调查(CHNS)数据,本研究对农村父母外出务工与留守子女初、高中阶段辍学行为之间的关系进行了实证分析。结果表明:父亲外出务工会显著降低留守子女初、高中阶段的辍学概率,母亲外出务工则会显著增加留守子女初中阶段的辍学概率。此外,免费义务教育政策的实施在较大程度上降低了留守子女的初、高中阶段的辍学概率;与那些父母受教育程度较低的留守子女相比,父母受教育程度越高的留守子女越不容易辍学;家庭子女数和机会成本会提高留守子女初中阶段辍学的概率。因此,为降低农村中学阶段子女辍学率,政府应当增加农村妇女当地就业机会以减少母亲外出的影响、推进户籍制度改革使随迁子女能获得同等的教育机会,并为高中阶段和多子女家庭提供教育补贴。 相似文献

This article proposes the coresearch engagement model (CoRE), which addresses how the academic research librarian can become a coresearch partner with any patron. The CoRE model is an interpersonal process and is founded upon the concepts of mutual respect, collaboration, reciprocity, and empowerment. Grounded in Howard Gardner’s multiple intelligences theory, Malcolm Knowles’ andragogical model, and guidelines from the Reference and User Services Association, CoRE has the potential to result in engagement for the librarian and patron. The CoRE model can be utilized in many ways including self-awareness and development for those who need and want to expand their abilities as a research librarian. It provides a theoretical framework and a knowledge base, in addition to giving a context for further development by expanding, comparing the related theories for further research, and implementing various applications suggested by this article. 相似文献

The initial time difference practical stability in terms of two measures has been investigated for nonlinear fractional differential equations in Caputo's sense and these properties have been unified with Lyapunov-like functions to establish a comparison result. 相似文献

The aim of this study was to investigate the relation of autonomous and controlling reasons underlying an endorsed achievement goal to intrinsic motivation and cheating. The endorsement of the achievement goal was ensured by involving 212 (Mage = 19.24, SD = .97) freshman students in a spatial task and asking them to report their most important achievement goal, as well as the reasons for adopting the goal, during the task. Results from a hierarchical regression analysis revealed that independent of the achievement goal the students adopted, the autonomous reasons for the endorsed goal were positively related to the indices of intrinsic motivation. Furthermore, the autonomous reasons underlying either performance or mastery-avoidance goals were negatively related to cheating. Alternatively, the controlling reasons for the endorsed goal were positively related to pressure and tension. The importance of considering both the ‘what’ and the ‘why’ aspect of achievement motivation are discussed. 相似文献

Research Findings: This study examined correlates of parents’ reported school engagement in an ethnically diverse, rural sample (N = 346) of parents and teachers in kindergarten through Grade 2. Of particular interest were role expectations and family–school relationships in American Indian families, who historically have been marginalized by schools. In terms of role expectations, parents and teachers agreed that they should support each other’s roles, parents should have more responsibility than schools for teaching social skills, and families and schools should have shared responsibility for children’s academic success. Teachers had higher expectations than parents for parent engagement, which in turn was greater when parent–teacher communication was more frequent and the school climate was more welcoming. American Indian parents more strongly endorsed a separation of family and school roles and felt less welcomed at school; ethnicity moderated correlates of reported parent engagement. Practice or Policy: These findings have practical promise given that parent–teacher communication, school climate, and role expectations are more easily altered than are structural barriers that also may hinder parents’ involvement in supporting their children’s early education. 相似文献
