DIAKONIE und DRG's: Antagonistisch oder vereinbar?

Im Reformprozess der evangelischen Kirche in Deutschland sind zwölf Handlungsfelder (Leuchtfeuer) herausgearbeitet worden, die diesen maßgeblich beeinflussen. Das achte Handlungsfeld ist die Diakonie und besitzt für die Kirche eine herausgehobene Bedeutung. Dies trifft auch auf die katholischen Einrichtungen zu. Die Einbindung der karitativen Arbeit in die Gestaltung des Sozialstaates macht diakonisches und karitatives Handeln von politischen Entscheidungen abhängig. Kirchliche Krankenhäuser müssen heute genauso im Wettbewerb des Gesundheitsmarktes bestehen wie staatlich geführte oder private Krankenhäuser. Ist dies unter den Bedingungen des Target Costings, wie sie die DRG's darstellen ein antagonistischer Widerspruch oder vereinbar? Diese Problematik soll mit der Entwicklung eines geeigneten Performance-Managementmodels unter theoretischer Bezugsnahme auf das Stakeholder-Ansatz-Konzept, eingebettet in die Systemtheorie, untersucht werden.In the reform process of the protestant church in Germany twelve action fields are very important. One of this is the Diaconie. The integration of this kind of work into the organization of the welfare state makes charity work acting dependent on political decisions. Hospitals run by the Protestant and Catholic Church have to exist in the competition of the health market. Is it an antagonistic contradiction or compatible under the conditions of target costing, represented by the DRG's? This problem will be examined. A suitable performance management model will be developed. The study is embedded into the system theory and the theory of the stakeholder concept

Asymptotic safety in the dark

We explore the Renormalization Group flow of massive uncharged fermions -- a candidate for dark matter -- coupled to a scalar field through a Higgs portal. We find that fermionic fluctuations can lower the bound on the scalar mass that arises from vacuum stability. Further, we discuss that despite the perturbative nonrenormalizability of the model, it could be ultraviolet complete at an asymptotically safe fixed point. In our approximation, this simple model exhibits two mechanisms for asymptotic safety: a balance of fermionic and bosonic fluctuations generates a fixed point in the scalar self-interaction; asymptotic safety in the portal coupling is triggered through a balance of canonical scaling and quantum fluctuations. As a consequence of asymptotic safety in the dark sector, the low-energy value of the portal coupling could become a function of the dark fermion mass and the scalar mass, thereby reducing the viable parameter space of the model.Comment: 16 pages plus appendix; 5 figure

Experimental evidence for a partially dissociated water bilayer on Ru{0001}

Core-level photoelectron spectra, in excellent agreement with ab initio calculations, confirm that the stable wetting layer of water on Ru{0001} contains O-H and H2O in roughly 3:5 proportion, for OHx coverages between 0.25 and 0.7 ML, and T<170 K. Proton disorder explains why the wetting structure looks to low energy electron diffraction (LEED) to be an ordered p(root3xroot3)R30degrees adlayer, even though approximate to3/8 of its molecules are dissociated. Complete dissociation to atomic oxygen starts near 190 K. Low photon flux in the synchrotron experiments ensured that the diagnosis of the nature of the wetting structure quantified by LEED is free of beam-induced damage

Generalized offsetting of planar structures using skeletons

We study different means to extend offsetting based on skeletal structures beyond the well-known constant-radius and mitered offsets supported by Voronoi diagrams and straight skeletons, for which the orthogonal distance of offset elements to their respective input elements is constant and uniform over all input elements. Our main contribution is a new geometric structure, called variable-radius Voronoi diagram, which supports the computation of variable-radius offsets, i.e., offsets whose distance to the input is allowed to vary along the input. We discuss properties of this structure and sketch a prototype implementation that supports the computation of variable-radius offsets based on this new variant of Voronoi diagrams

weSPOT: a cloud-based approach for personal and social inquiry

Scientific inquiry is at the core of the curricula of schools and universities across Europe. weSPOT is a new European initiative proposing a cloud-based approach for personal and social inquiry. weSPOT aims at enabling students to create their mashups out of cloud-based tools in order to perform scientific investigations. Students will also be able to share their inquiry accomplishments in social networks and receive feedback from the learning environment and their peers
