PURPOSE This study examines the integration effects on efficiency and financial viability of the top 100 integrated healthcare networks (IHNs) in the United States. THEORY A contingency-strategic theory is used to identify the relationship of IHNs' performance to their structural and operational characteristics and integration strategies. METHODS The lists of the top 100 IHNs ranked in two ...

Two point fully implicit block method of variable step size is developed for solving directly the second order system of Ordinary Differential Equations (ODEs). This method will estimate the solutions of Initial Value Problems (IVPs) at two points simultaneously. The method developed is suitable for the numerical integration of non stiff and mildly stiff differential systems. Numerical results ...

In this paper we study the issue of economic integration in Poland between 1924 and 1937 by means of a threshold cointegration analysis of the law of one price. We find that the interwar economy can be regarded as integrated but with obvious restrictions which refer to the existence of relevant transaction costs for arbitrage and differences in the level of prices between cities. Moreover, the ...

cretization of certain boundary integral equations on a very general class of two-dimensional domains with corner points. The resulting quadrature rules allow for the rapid high accuracy solution of Laplace’s equation and the Helmholtz equation on such domains. Our approach can be adapted to many other boundary value problems as well as to the case of surfaces with singularities in three dimens...

The parallel version of the multidimensional numerical integration package Cuba is presented and achievable speed-ups discussed.

A new numerical integration code (COLDDAE) for general linear differentialalgebraic equations (DDAEs) of retarded and neutral type is discussed. The implementation is based on the regularization technique introduced in [13]. In the single delay case, the code can handle noncausal systems, i.e., systems, where the solution at the current time does not only depend on the system at the past and cu...

The proper application of a shadow model during the integration of orbit trajectories requires that the solar radiation pressure be sampled adequately during transitions between lighting conditions. An integration scheme is presented in which the lighting condition is held constant across steps of a primary integrator. If the lighting condition changes during that step, then an Encke-like integ...
