Sprache und Ohr des Herzens. Über die Bedeutung der Musik in der Liturgie

Meine Damen und Herren, vielleicht haben Sie sich unter einem Mönch etwas anderes vorgestellt: langsam, bedächtig einherschreitend, mit gleichförmiger, ruhiger Musik – bis die Musik, um nicht zu sagen: er selbst zum Eiswürfel gefroren, hieratisch starr und unbeweglich geworden ist. Und es gibt solche Vorstellungen, auch in Mönchskreisen, wo die Musikgeschichte mit Mozart und Schubert aufhört. Schon der Dreivierteltakt ist gefährlich, besonders als Walzer, weil er in die Beine geht. Musik gehört den höheren Sphären an. Rockmusik gilt in solchen Kreisen als Teufelsmusik, dabei kann der Teufel gar nicht singen (Max Brewer: „Tausend Künste kennt der Teufel, aber singen kann er nicht; denn Gesang ist ein Bewe- gen unsrer Seele nach dem Licht.“).

Design of robustly performing controllers for a class of practical control problems

The design of robustly performing controllers for a class of practical control problems is considered, involving both parametric and unstructured uncertainty. The problem is dealt with in the structured singular value (μ)-framework. An iterative approach comprising both μ-analysis of the detailed problem and D-K-iteration for a modified problem is proposed, as no direct solution to the detailed μ-synthesis problem is known to date. With a practical MIMO process control example it is shown that this approach leads to controllers that exhibit robust performance

A computed tomography based survey study investigating the agreement of the therapeutic strategy for fragility fractures of the pelvis

Treatment recommendations for fragility fractures of the pelvis (FFP) have been provided along with the good reliable FFP classification but they are not proven in large studies and recent reports challenge these recommendations. Thus, we aimed to determine the usefulness of the FFP classification determining the treatment strategy and favored procedures in six level 1 trauma centers. Sixty cases of FFP were evaluated by six experienced pelvic surgeons, six inexperienced surgeons in training, and one surgeon trained by the originator of the FFP classification during three repeating sessions using computed tomography scans with multiplanar reconstruction. The intra-rater reliability and inter-rater reliability for therapeutic decisions (non-operative treatment vs. operative treatment) were moderate, with Fleiss kappa coefficients of 0.54 (95% confidence interval [CI] 0.44–0.62) and 0.42 (95% CI 0.34–0.49). We found a therapeutic disagreement predominantly for FFP II related to a preferred operative therapy for FFP II. Operative treated cases were generally treated with an anterior–posterior fixation. Despite the consensus on an anterior–posterior fixation, the chosen procedures are highly variable and most plausible based on the surgeon’s preference.Publikationsfonds ML
