Theoretical and methodological implications of associations between executive function and mathematics in early childhood

Despite agreement about the importance of executive function (EF) for children’s early math achievement, its treatment in correlational studies reflects a lack of agreement about the theoretical connection between the two. It remains unclear whether the association between EF and math operates through a latent EF construct or specific EF components. Specifying the correct measurement model has important theoretical implications for the predicted effects of EF interventions on children’s math achievement. In the current study, we tested whether associations between EF and math operate via a latent EF factor, or via specific EF components using data from a large, nationally representative sample. We then replicated these same analyses with a meta-analytic database drawn from ten studies that collected measures of children’s EF and math achievement. Our results lend support to explanations that a single EF factor accounts for most of the EF component-specific associations with math achievement. We discuss theoretical and methodological implications of these findings for future work.

全球及中国可持续发展目标进展与挑战

实现17项联合国可持续发展目标（SDGs）是世界各国在2016—2030年的重要任务,但近期评估显示有半数目标进展停滞甚至倒退,并且到2030年世界各国可能无法实现大多数目标。文章在回顾全球及中国实现17项SDGs进展的基础上,总结了影响SDGs实现的5项主要挑战,包括：数据缺失和监测能力不足,不同SDGs间相互联系的高度复杂性,区域差异和负外部性影响,科学、政策和社会联系不足,以及全球变化对SDGs实现的不确定性影响。同时,文章从加强政策一致性、聚焦优先目标、强化基础理论研究、提升数据获取能力4个方面提出了加快中国实现SDGs的对策建议。

Leveraging microgrants to support capacity-building workshops in low- and middle-income countries for meeting the Sustainable Development Goals

Twenty fifteen marked the year of assessment for the Millennium Development Goals (MDGs). The MDGs that achieved the greatest success were those where evidence-based practice (EBP) interventions were implemented. The ability to practice evidence-based medicine is grounded in the creation of and access to medical literature that synthesizes research findings. The role that global health literature played in the success of the MDGs demonstrates that medical libraries and librarians have a role to play in achieving the Sustainable Development Goals (SDGs).Librarians can hold capacity-building workshops that provide instruction on how to access evidence-based literature and also train health professionals to conduct synthesis research. Research findings conducted by in-country health professionals are more likely to address issues being faced by local communities and will afford the possibility of obtaining the necessary evidence-based answers that can then be used to implement policies to resolve public health issues identified in the SDGs.This paper discusses how an international team of librarians leveraged funding from a Medical Library Association/Librarians without Borders/Elsevier Foundation/Research4Life grant to hold a capacity-building workshop in Zimbabwe and follow-up online trainings. The workshop focused on accessing evidence-based resources and conducting synthesis research. Outcomes included the creation and policy implementation of evidence-based knowledge products in alignment with local needs and galvanizing a multisectoral group of key individuals who have gone on to collaborate toward the vision of creating a Zimbabwe innovation hub. Looking ahead, such grants can be leveraged to conduct capacity-building to support knowledge translation and other local training needs.

都市郊区土地开发整理项目的农户土地利用机会成本分析

土地整理作为一项具有正外部性的公共事业,要获得健康、快速和可持续发展,就必须得到广大农民的参与和支持。本文结合北京郊区区县土地整理前后农户土地利用状况的调研,探讨了当前城市化过程中,城郊农户面临的土地发展权让渡机会成本、经营方式选择机会成本和就业选择机会成本,以期为土地开发整理工作的推进和落实提供相关政策建议和参考。结论认为：①土地开发整理在发挥增加耕地面积、提高耕地等级等正效益的同时,所导致的土地利用方式单一和转用、经营限制正使农户承担着较多的机会成本;②土地发展权让渡机会成本和经营方式选择机会成本是农户选择权受到制度限制而造成的,其本质是土地开发整理这一公共产品社会成本的转嫁,而非农就业机会造成的耕地利用率低则是农户作为经济人的理性选择;③合理的发展权补偿、整理后土地利用经营方式的灵活选择和农产品公共物品补贴是提升都市郊区土地开发整理项目实施效益的关键。
