ACE基因多态性与2型糖尿病的关联研究

目的探讨血管紧张素转化酶(ACE)基因I/D多态性在湖北汉族2型糖尿病发生发展中的作用。方法采用同胞对和随机病例-对照两种实验设计。征集湖北地区汉族49个同胞对及163例随机病例-对照,测定身高、体重、血压、空腹血糖等生理生化指标,应用聚合酶链反应(PCR)方法测定基因型。结果两种实验设计中对照组与病例组的基因型和基因频率均无显著差异。结论ACE基因在湖北汉族人群2型糖尿病的发生发展中可能不起主要作用。

激光刀口法声表面波分布图像化系统

介绍了激光刀口法声表面波(SAW)分布图像化高速测量系统的原理和系统构成,并进行了测试验证。通过将声表面波传播时引起的被测件表面微变转换为入射到光电二极管的光量变化,转换出的电信号下变频到中频进行检波和鉴相后输入到高速数据采集器,实现了约20min测试2620(x)×410(y)点阵,获取的声表面波振幅和相位数据重构声表面波分布的图像。

CRITICAL PERIODS DURING CHILDHOOD AND ADOLESCENCE

We identify the ages that constitute sensitive (or critical) periods in children's development towards their adult health status, skills, and human capital. For this, we use data on families migrating into Sweden from countries that are poorer, with less healthy conditions. Late‐life health is proxied by adult height and other adult outcomes. The relation between siblings’ ages at migration and their adult outcomes allows us to estimate the causal effect of conditions at specific childhood ages. We effectively exploit that, for siblings, the migration occurs simultaneously in calendar time but at different developmental stages (ages). We find evidence that the period just before the puberty growth spurt constitutes a critical period for adult height and we find related critical periods for adult cognition, mental health, and education.     

长江经济带城市制造业集聚的空间外部性:识别与应用

文章运用双变量莫兰指数研究了长江经济带130个城市制造业集聚的空间外部性。首先，测算了城市的经济发展指数和环境污染指数，以制造业为中心变量运用双变量莫兰指数测算了制造业与城市经济发展指数以及环境污染指数间的空间自相关性，得到了长江经济带上表现出经济外部性和环境外部性的城市；其次，从影响城市特征属性的因素出发，通过城市区位、城市发展定位与规划以及城市科技创新能力等因素分析了城市空间外部性的产生机理；最后，在识别具体城市外部性类型与表现的基础上，从城市政策体系、资源信息、产业结构和生态环境几个方面提出了对城市制造业空间外部性的应用，实现长江经济带城市空间联动效应。     

The Determinants and Some Consequences of Unemployed Workers' Wage Demands

This paper studies the determinants and consequences in the early stages of the hiring process of unemployed workers' wage demands using direct data on workers' wage requests. We show that most unemployed workers want a wage close to their previous wage, and thus much more than they get in unemployment benefits. However, some groups, such as women, tend to demand lower wages. Moreover, we find that workers with high wage demands are contacted by firms less often than otherwise similar workers with lower wage demands. Thus, our results suggest that too high wage demands may contribute to high unemployment.     

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.
