Numerical Insights Into the Resistance Reduction Mechanisms of Forward Tapered Transoms in High‐Speed Catamaran: A Computational Fluid Dynamics‐Based Study

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study investigates the hydrodynamic influence of forward transom tapering on a displacement catamaran hull using computational fluid dynamics (CFD) simulations. Five taper configurations ranging from a vertical transom base design to a fully tapered stern (1.00B) were evaluated over a wide Froude number range (Fr = .3 to 1.0).

Where Have I Seen You Before? Networks, Trust and Reciprocity as a Source of Collaboration in the Public Service

Public Administration and Development, EarlyView.
ABSTRACT Although some studies focus on how bureaucrats' interactions with one another affect performance, they rarely focus on why these public servants collaborate. Bureaucrats' collaboration matters because it can significantly contribute to achieving policy goals.
