Growth Mindset Training and the Effect of Math-Gender Stereotype Threat on Girl Students
No full textTo investigate whether growth mindset training can weaken the effect of math-gender stereotype threat on girl students, this study undertook experimental intervention in a group of grade-11 girl students and found that: (i) Mindsets can moderate the effect of math-gender stereotype threat. Girls with a growth mindset are less likely to be affected by math-gender stereotype threat compared with those with a fixed mindset. (ii) Growth mindset training for girls with a fixed mindset can effectively reduce the effect of math-gender stereotype threat on their math performance
Family support or social support: evidence from family planning policy in China
No full textIn this study we use the Family Planning Policy as our exogenous shock to identify whether having fewer children will influence parents’ insurance participation. By using 2005 and 2015 Mini-Census data, we found that having less boys made rural parents less involved in social security programs (including pension and medical insurance), while having less girls will not affect insurance participation significantly. To take a step further, we found that the Q-Q theory is verified in boys rather than girls. For children of rural mothers, boy’s income and education level are significantly improved when having fewer siblings. This is reasonable considering rural families have stricter budgetary constraints and value boys more than girls. To sum up, in rural areas, family planning policy decreased fertility as well as increased the boy ratio, which decrease parents’ participation in social security systems. When boys have fewer siblings, their education and income increase significantly, and can thus ensure their parents a good life in their older age, which reduces the need for pension and medical insurance.在本研究中，我们以计划生育政策作为我们的外生冲击，来识别少生子女是否会影响父母的参保。通过使用2005年和2015年的人口普查数据，我们发现少生男孩会使农村父母减少对社会保障项目（包括养老保险和医疗保险）的参与，而少生女孩则不会显著影响保险参与。更进一步的研究发现，Q-Q理论在男孩而不是女孩身上得到了验证。对于农村母亲的孩子来说，当兄弟姐妹数量减少时，男孩的收入和教育水平都会有显著提高。考虑到农村家庭的预算约束比较严格，且对男孩的重视程度高于女孩，这样的发现合乎情理。综上所述，在农村地区，计划生育政策降低了生育率，同时也提高了男孩的比例，降低了父母对社会保险的参与度。当男孩的兄弟姐妹数量减少时，他们的教育和收入显著增加，从而可以保证父母在老年时过上好日子，减少对养老金和医疗保险的需求。Zhang, Shujuan.M.Phil.
