基于课程思政建设的"工程伦理"本土教学案例开发研究

"工程伦理"课程承担着对未来工程科技人才进行价值塑造的教育使命,可是本土教学案例开发价值取向的模糊,以及内容选择上的保守让"工程伦理"难以彰显课程思政功能.基于课程思政建设的具体要求,"工程伦理"本土教学案例开发在价值取向上,应扎根中华传统的文化根脉和精神家园,积极面向中国民族工业发展和人类工程实践的现实生活世界,并在脚本设计上实现全球的共享和对话.在内容选择上,开发彰显当代中国工程精神诸要素的民族工业发展案例、当前中国工程实践中出现的典型或特色案例,以及彰显新时代中国担当的工程跨文化实践案例.     

Interventions in child welfare: A Swedish inventory

In Swedish child welfare, there are no mandatory guidelines on what interventions to use. Local authorities are able to set their own criteria for implementing or designing interventions. We carried out a survey to identify interventions in use in Children's Social Services and Child and Adolescent Psychiatric Care in Sweden. A total of 102 interventions were stated to have been in use, with between 31 and 45 different interventions for each of the four different child welfare populations. Of the 102 interventions, 56 were designed outside Sweden and later imported. Only 27 interventions were supported with some kind of research evidence. About half of the interventions targeted the child. Possible implications for practice and research are discussed.     

How Important is Selection? Experimental VS. Non‐Experimental Measures of the Income Gains from Migration

How much do migrants stand to gain in income from moving across borders? Answering this question is complicated by non‐random selection of migrants from the general population, which makes it hard to obtain an appropriate comparison group of non‐migrants. New Zealand allows a quota of Tongans to immigrate each year with a random ballot used to choose among the excess number of applicants. A unique survey conducted by the authors allows experimental estimates of the income gains from migration to be obtained by comparing the incomes of migrants to those who applied to migrate, but whose names were not drawn in the ballot, after allowing for the effect of non‐compliance among some of those whose names were drawn. We also conducted a survey of individuals who did not apply for the ballot. Comparing this non‐applicant group to the migrants enables assessment of the degree to which non‐experimental methods can provide an unbiased estimate of the income gains from migration. We find evidence of migrants being positively selected in terms of both observed and unobserved skills. As a result, non‐experimental methods other than instrumental variables are found to overstate the gains from migration by 20–82%, with difference‐in‐differences and bias‐adjusted matching estimators performing best among the alternatives to instrumental variables.
