二十四节气融入幼儿园教育活动的行动研究——以云南省曲靖市W幼儿园为例

二十四节气融入幼儿园教育活动有助于促进文化传承及幼儿身心全面发展,增进幼儿民族自豪感。通过感知体验、初步认识、丰富理解、拓展提升四轮二十四节气融入幼儿园教育活动的行动研究,结果显示:二十四节气融入幼儿园教育活动促进了幼儿、教师及幼儿园等多方面的发展,但也存在着研究方案设计缺乏整体性与灵活性、幼儿对节气文化探索兴趣不高、教师缺少对节气融入教育活动的深入思考等问题。为此,应该从转变思想、选择资源、提升素养、创设环境等方面完善二十四节气融入幼儿园教育活动的行动研究。     

A GLOBAL VIEW OF CROSS‐BORDER MIGRATION

This paper evaluates the global welfare impact of observed levels of migration using a quantitative multi‐sector model of the world economy calibrated to aggregate and firm‐level data. Our framework features cross‐country labor productivity differences, international trade, remittances, and a heterogeneous workforce. We compare welfare under the observed levels of migration to a no‐migration counterfactual. In the long run, natives in countries that received a lot of migration—such as Canada or Australia—are better off due to greater product variety available in consumption and as intermediate inputs. In the short run, the impact of migration on average welfare in these countries is close to zero, while the skilled and unskilled natives tend to experience welfare changes of opposite signs. The remaining natives in countries with large emigration flows—such as Jamaica or El Salvador—are also better off due to migration, but for a different reason: remittances. The welfare impact of observed levels of migration is substantial, at about 5% to 10% for the main receiving countries and about 10% in countries with large incoming remittances.     

The Motherhood Wage Penalty and Its Determinants: A Public–Private Comparison

We investigate whether public and private sector employees bear a different wage penalty for having children. According to our estimates, the total motherhood wage penalty is much larger in the private than in the public sector. Nevertheless, in both sectors, we find no unexplained penalty once we control for potential determinants of the family pay gap, namely, a reduced labour supply of mothers, child‐related career interruptions, less access to management positions, and adjustments in working conditions. Finally, only child‐related career interruptions play a different role in explaining the motherhood wage penalty in each sector.
