Strategic Change, EarlyView.ABSTRACT The increasing prevalence of corporate scandals and dysfunction linked to psychopathic leaders has prompted significant research into the drivers and effects of psychopathy in business. This paper examines corporate psychopathy, focusing on individuals with extreme selfishness, callousness, and manipulative behavior who often achieve ...

The Bazaar as a Model for Knowledge Work
Knowledge and Process Management, EarlyView.ABSTRACT This paper presents fieldwork that extends existing metaphors of knowledge work as a process shaped by hierarchical or market forces. A qualitative, ethnographic study of six knowledge‐intensive businesses in two countries identifies striking parallels with the Middle Eastern bazaar in contrast to Western impersonal markets and hierarchies. We

Inverse Design of Mirror‐Symmetric Disordered Systems for Broadband Perfect Transmission
Laser &Photonics Reviews, EarlyView.This work introduces an inverse design approach to achieve broadband perfect wave transmission in mirror‐symmetric disordered media. Leveraging symmetry simplifies optimization and enables control of multiple reflectionless states. Experiments in microwave waveguides confirm the design of exceptional points, bandpass filters, and broadband quasi ...

Frozen Differential Scattering in Reconfigurable Complex Media
Laser &Photonics Reviews, EarlyView.A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...

Multimode Phonon Lasing via Self‐Induced Optical Coherent Pumping
Laser &Photonics Reviews, EarlyView.A silicon optomechanical nanobeam generates self‐sustained phonon lasing in multiple competing mechanical modes via self‐pulsing, an intrinsic optical modulation arising from cavity nonlinearity. This self‐organized mechanism enables robust multi‐frequency operation spanning periodic, quasi‐periodic, and chaotic regimes without external modulation. The
