Using a rich dataset on organizational characteristics and Internet investment by over 100 firms in the insurance industry, we show that vertical integration in distribution has a significant impact on the speed with which insurers adopt consu...

Lidars have been employed in the investigation of instantaneous vertical structure of atmospheric particulate. Remote measurements of particle backscattering and aerosol extinction coefficient provide the altitude distribution of particles existence in the atmosphere. This paper describes the technology of micro pulse lidar employed for computation of altitude profiles of particle backscatterin...
