Average Wage, Qualification of the Workforce and Export Performance in German Enterprises: Evidence from KombiFiD Data Empirical investigations with enterprise level data from official statistics often use the average wage as a proxy variable for the qualification of the workforce, mostly due to the lack of detailed information on the qualification of the employees. This paper uses unique newly...

The development and implementation of new materials and manufacturing processes for aerospace application is often hindered by the high cost and long time span associated with current qualification procedures. The data requirements necessary for material and process qualification are extensive and often require millions of dollars and multiple years to complete. Furthermore, these qualification...

OBJECTIVE To study the association between time to antibiotic administration and survival in patients with severe sepsis or septic shock in whom early goal-directed therapy was initiated in the emergency department. DESIGN Single-center cohort study. SETTING The emergency department of an academic tertiary care center from 2005 through 2006. PATIENTS Two hundred sixty-one patients undergo...

BACKGROUND Limited evidence exists whether practice patterns of general practitioners (GPs) who have additionally completed training in naturopathy are different from those of conventional GPs. We aimed to assess and compare practice patterns of GPs in conventional and naturopathic GPs. METHODS Routine data from 41 GPs (31 with and 11 without additional qualification in NP, respectively) and ...

This article illustrates a model selection management approach for virtual prototypes in interactive simulations. In those numerical simulations, the virtual prototype and its environment are modelled as a multi-agent system, where every entity (prototype, human, etc.) is modelled as an agent. In particular, virtual prototyping agents that provide mathematical models of mechanical behaviour in ...

Formal methods tools have been shown to be effective at finding defects in safety-critical systems, including avionics systems in commercial aircraft. The publication of DO-178C and the accompanying formal methods supplement DO-333 provide guidance for aircraft manufacturers and equipment suppliers who wish to obtain certification credit for the use of formal methods for software development an...

The constant-rank condition for feasible points of nonlinear programming problems was defined by Janin (Math. Program. Study 21:127–138, 1984). In that paper, the author proved that the constant-rank condition is a first-order constraint qualification. In this work, we prove that the constant-rank condition is also a secondorder constraint qualification. We define other second-order constraint ...
