AbstractGovernments across the globe try to rebalance their budgets by rationalizing overhead operations. When overhead‐reducing policies are adopted, it is important to understand why some central government organizations have a higher overhead than others, and why organizational models to produce overhead efficiencies are used to different degrees. This study focuses on the Flemish context to analyse differences between central government organizations in the size and organization of two overhead processes: human resources management (HRM) and finance and control (FIN). Significant effects are found for autonomy, organizational size, spatial dispersion and budgetary stress, yet effects vary according to whether HRM or FIN is considered and whether the focus is on the size or the organization of HRM or FIN. Our findings have practical implications to get a process‐sensitive understanding of the size and organization of overhead, and theoretical implications as they cast light on factors that shape decision‐making in public organizations.

This paper presents results obtained between 2010 and 2014 in the field of fan aerodynamics at the Department of Composite Technology at the VZLÚ aerospace research and experimental institute in Prague – Letnany. The need for rapid and accurate methods for the preliminary design of blade machinery led to the creation of a mathematical model based on the basic laws of turbomachine aerodynamics. The mathematical model, the derivation of which is briefly described below, has been encoded in a computer programme, which enables the theoretical characteristics of a fan of the designed geometry to be determined rapidly. The validity of the mathematical model is assessed continuously by measuring model fans in the measuring unit, which was developed and manufactured specifically for this purpose. The paper also presents a comparison between measured characteristics and characteristics determined by the mathematical model as the basis for a discussion on possible causes of measured deviations and calculation deviations.
