Hurricane Andrew, which made landfall on August 24, 1992, was one of the most destructive hurricanes in American history, causing atypically high levels of psychological and physical health impairment among the resident population and especially among vulnerable groups. This article investigates whether maternal exposure to Hurricane Andrew during pregnancy increased the risk of dystocia (or dy...

skilled labor force is very important in economic growth. workers become skilled when they are healthy and able to be educated and work. in this study, we estimated the effects of health indicators on labor supply. we used labor force participation rate as the indicator of labor supply. we categorized this indicator into 2 indicators of female and male labor force participation rates and compar...

We investigate the effects of interregional labor market integration on the dynamic interaction between migration and capital formation through changes in house prices. The nature of this interaction depends on initial conditions at the time of labor market integration. In an initially capital-poor economy, there may be a reversal of migration during the transition to the steady state, like obs...

This paper introduces a new IV strategy based on IVF (in vitro fertilization) induced fertility variation among childless women to estimate the causal effect of having children on their career. For this purpose, we use administrative data on IVF treated women in Denmark. Because observed chances of IVF success do not depend on labor market histories, IVF treatment success provides a plausible i...

KEY FINDINGS The highest percentages of births occurred during the morning and midday hours. Births on Saturday and Sunday were more likely to occur in the late evening and early morning hours than births Monday through Friday. Compared with induced vaginal deliveries and noninduced vaginal deliveries, cesarean deliveries were the least likely to occur during the evening and early morning. Noni...

For most of human history, the environmental demands of survival necessitated prodigious amounts of physical exertion. The avoidance of predators, hunting, gathering, and the literal "chopping wood and carrying water" of daily existence provided a wholesome dose of physical activity that obviated the need for deliberate exercise. Nevertheless, 21st century humans are now immersed within an envi...

Using data drawn from the Canadian, Mexican, and U.S. censuses, we find a numerically comparable and statistically significant inverse relation between immigrant-induced shifts in labor supply and wages in each of the three countries: A 10% labor supply shift is associated with a 3%-4% oppositesigned change in wages. Despite the similarity in the wage response, the impact of migration on the wa...

In many decentralized labor markets, job candidates are offered positions at very early stages in the hiring process. It has been argued that these early offers are an effect of the competition between employers for the best candidate. This work studies the timing of offers in a theoretical model based on the classical secretary problem. We consider a secretary problem with multiple employers a...

Plasma cortisol was measured in cord and neonatal blood. Cortisol concentration in neonates decreased rapidly during the first three days after delivery and thereafter remained at an almost constant level. The more the delivery was stressful, the higher the cortisol in the 1-day-old infant, but the concentration came down to the same level as in the less stressful delivery on the 3rd day of the...

atp-sensitive potassium (katp) channel openers have a relaxation effect due to the lower cellular membrane potential and inhibit calcium influx. there has been considerable interest in exploring katp channel openers in the treatment of various diseases such as cardiovascular, cerebrovascular, and urinary system disease and premature labor. the purpose of this study was to synthesize 3,3,6,6-tet...
