Energy is consumed in the industrial sector by a diverse group of industries includingmanufacturing, agriculture, mining, and construction and for a wide range of activities, such as processing and assembly, space conditioning, and lighting...
We investigate the impact of household use of labor-saving farm technologies on first-time out-migration after the household agriculture and consumption survey was conducted in 1996. Building on the labor substitution framework, we hypothesize that household use of labor-saving technologies (e.g., tractors, farm implements, chemical fertilizers, and pesticides) increases individual out-migratio...
A hundred years ago in July, thanks to the advancement of medical technology, first human received vaccine Bacille Calmette-Guérin—or BCG—to prevent tuberculosis (TB), a disease that killed at least 20% European population during 19th century. Since then, hundreds millions lives have been saved by BCG, as well other vaccinations for dangerous diseases. However, although TB is quite preventable ...
