Delineating the corporate elite: Inquiring the boundaries and composition of interlocking directorate networks.

Corporate elite studies have for long investigated networks of interlocking directorates to test and corroborate key theoretical expectations regarding the cohesive organization of such an elite and their ability and willingness to act on behalf of general business interests. These studies typically collect data on a list of 50, 100, 200 or 500 corporations ranked by economic size, sometimes stratified in sectors. The sampling approach often follows previous studies in order to increase comparability.

Comparison of seven videolaryngoscopes with the Macintosh laryngoscope in manikins by experienced and novice personnel.

Videolaryngoscopy is often reserved for 'anticipated' difficult airways, but thereby can result in a higher overall rate of complications. We observed 65 anaesthetists, 67 residents in anaesthesia, 56 paramedics and 65 medical students, intubating the trachea of a standardised manikin model with a normal airway using seven devices: Macintosh classic laryngoscope, Airtraq(®) , Storz C-MAC(®) , Coopdech VLP-100(®) , Storz C-MAC D-Blade(®) , GlideScope Cobalt(®) , McGrath Series5(®) and Pentax AWS(®) ) in random order. Time to and proportion of successful intubation, complications and user satisfaction were compared.
