Boys left behind: The effects of summer camp and follow-up strategies on academic,personal, and social competencies

I use Danish administrative data to investigate the consequences of summer camp participation combined with a one-year follow-up program for disadvantaged boys on academic, personal, and social competencies. My identification strategy relies on individual-level panel data that enable me to observe outcomes before and after summer camp participation. Using a difference-in-differences strategy, I find overall positive effects on academic and personal competencies that reduce the gap to a matched group of boys with similar background characteristics by 40 to 80 percent. Further, I exploit a structural change in the follow-up program to evaluate how different mentoring strategies affect outcomes. In 2017, the follow-up program was changed from individual mentoring to group mentoring. Using a triple differences strategy, I find that group mentoring in the follow-up program improves personal and social competencies, suggesting that the format of the follow-up program is crucial for effects on personal and social competencies.

土地资源是不可再生资源,是国民经济和社会发展的重要基础,大力推进节约集约用地是严格保护土地资源与保障发展的最佳结合和最优选择。以南丰县为例,分析南丰县建设用地现状及建设用地节约集约利用存在的主要问题,通过建立建设用地节约集约利用评价指标体系和评价模型,对现状建设用地集约度进行评价,并在其基础上提出了建设用地节约集约利用的规划指标控制标准,针对南丰县的实际情况提出了节约集约用地的对策和建议。     

Dynamic reciprocal relations of achievement goals with daily experiences of academic success and failure: An ambulatory assessment study

Achievement goals have been linked to achievement in various educational settings. The present work explored day-to-day variations in achievement goals (mastery, performance-approach, performance-avoidance) and their associations with daily experiences of academic success and failure. Ambulatory assessment data from 108 students in Grade 5 were collected, with daily assessments of achievement goals in the morning and end-of-day reports of academic success and failure. Dynamic structural equation models revealed reciprocal within-person effects between mastery goals and academic success. Academic success was further associated with higher mastery and performance-approach goals in the next morning. Academic failure was linked to both performance goals, though this association was not robust in all sensitivity analyses. Higher average daily academic success and lower average academic failure were linked to better academic achievement one year later. Findings suggest meaningful within-person dynamics among goals and daily academic success and failure.

高职英语听说先行项目化教学的设计

高职英语教学要突出技能性、可操作性和职业性的特点,结合听说法和项目化教学的实践成果,确定了高职英语听说先行整体教学方案设计,提供了单元设计案例,并进行了为期1年的实践,教学效果良好。但是,由于课时限制以及学生水平的参差不齐等因素的影响,高职英语听说先行项目化教学设计和实践效果还需进一步的探索和检验。     

表面肌电图在人体运动研究中的应用

肌肉运动时会有微小的生物电变化，表面肌电图作为一种无创的检测方法来检测这种生物电变化。运动时肌电图的振幅、频率等指标均会产生相应的变化，而且这些变化与运动方式、运动状态、肌肉疲劳密切相关。     

800 m运动员大强度训练后免疫球蛋白低下的影响机制及调理措施

在800m运动项目中,为了实现训练和比赛的目标,科学的制定运动负荷量十分必要。负荷适宜且恢复措施及时,机体就会出现良好的适宜性变化;训练负荷太小,运动能力提高就不明显;训练负荷过大,会出现过度训练,免疫力低下等问题。本文通过文献资料法来探讨高校800m运动员大强度训练前后免疫球蛋白的变化特征并根据变化特点科学的进行调理。
