We have studied the performance of polytetrafluoroethylene integrating spheres in the ultraviolet (UV) region with wavelengths as short as 200 nm. Two techniques were used for this study; first, the spectral throughput of an integrating sphere irradiated by a deuterium lamp was analyzed by a monochromator. Second, a UV laser beam was directed into an integrating sphere, and spectrally dispersed...

The South African Facilities Management (FM) industry has seen increased operational strategy complexity from single-site contractors providing basic janitorial services to highly integrated and bundled FM service providers.  Despite these major changes, very little research has been conducted on evaluating the effectiveness of FM in innovating, integrating and aligning business strategies to a...

In 1955, Herbert Simon introduced the notion of satisficing: an agent satisfices by searching for alternative that meets aspiration level but does not optimize. We survey more than 60 years advances in understanding satisficing economics, psychology, and management, identifying two research traditions address classes situations: under risk, is typically inferior to optimization strategies model...
