Die Entscheidung in der Rechtssache Bohez /Wiertz bot dem EuGH Gelegenheit, zur Abgrenzung der Anwendungsbereiche von Brüssel I-(jetzt: Brüssel Ia-) und Brüssel IIa-VO Stellung zu nehmen. Den Ausgangspunkt bildete dabei ein familienrechtlicher Sachverhalt, nämlich die zwangsweise Durchsetzung des Umgangsrechts eines Vaters im Hinblick auf seine beiden Kinder. Auf den ersten Blick lag daher eine Anwendung der auf Verfahren betreffend die elterliche Verantwortung bezogenen Brüssel IIa-VO nahe. Andererseits schien auch eine Argumentation denkbar, wonach es sich bei dem zu vollstreckenden Anspruch auf Zahlung des Zwangsgeldes um eine Geldforderung handele, deren Vollstreckung nach der Brüssel I-VO zu erfolgen habe.
Was vordergründig die Ermittlung des einschlägigen EU-Rechtsaktes betraf, erwies sich bei genauerer Betrachtung als Bestimmung der dogmatischen Rechtsnatur des Zwangsgeldes.

Software development projects often fail because of insufficient code quality. It is now well documented that the task of testing software, for example, is perceived as uninteresting and rather boring, leading to poor software quality and major challenges to software development companies. One promising approach to increase the motivation for considering software quality is the use of gamification. Initial research works already investigated the effects of gamification on software developers and come to promising. Nevertheless, a lack of results from field experiments exists, which motivates the chapter at hand. By conducting a gamification experiment with five student software projects and by interviewing the project members, the chapter provides insights into the changing programming behavior of information systems students when confronted with a leaderboard. The results reveal a motivational effect as well as a reduction of code smells.
Process mining gets more and more attention even outside large enterprises and can be a major benefit for small and medium sized enterprises (SMEs) to gain competitive advantages. Applying process mining is challenging, particularly for SMEs because they have less resources and process maturity. So far, IS researchers analyzed process mining challenges with a focus on larger companies. This paper investigates the application of process mining by means of a case study and sheds light into the particular challenges of an IT SME. The results reveal 13 SME process mining challenges and seven guidelines to address them. In this way, the paper contributes to the understanding of process mining application in SME and shows similarities and differences to larger companies.
Kaum ein anderer Begriff hält so viele Varianten und Facetten bereit wie die Arbeitszeit. Für die betriebliche Praxis stellt sich dabei regelmäßig die Frage, was überhaupt zur Arbeitszeit gehört, entsprechend als solche zu vergüten ist und welche Optionen bei der Gestaltung der Arbeitsverträge bestehen. Der folgende Praxisleitfaden gibt einen Überblick über die aktuelle Rechtslage und enthält zugleich Hinweise für die Vertragsgestaltung. Die hierzu insbesondere in den letzten Jahren ergangenen zahlreichen aktuellen Gerichtsentscheidungen werden besonders berücksichtigt.
Lifting propellers are of increasing interest for Advanced Air Mobility. All propellers and rotors are initially twisted beams, showing significant extension–twist coupling and centrifugal twisting. Torsional deformations severely impact aerodynamic performance. This paper presents a novel approach to assess different reasons for torsional deformations. A reduced-order model runs large parameter sweeps with algebraic formulations and numerical solution procedures. Generic beams represent three different propeller types for General Aviation, Commercial Aviation, and Advanced Air Mobility. Simulations include solid and hollow cross-sections made of aluminum, steel, and carbon fiber-reinforced polymer. The investigation shows that centrifugal twisting moments depend on both the elastic and initial twist. The determination of the centrifugal twisting moment solely based on the initial twist suffers from errors exceeding 5% in some cases. The nonlinear parts of the torsional rigidity do not significantly impact the overall torsional rigidity for the investigated propeller types. The extension–twist coupling related to the initial and elastic twist in combination with tension forces significantly impacts the net cross-sectional torsional loads. While the increase in torsional stiffness due to initial twist contributes to the overall stiffness for General and Commercial Aviation propellers, its contribution to the lift propeller’s stiffness is limited. The paper closes with the presentation of approximations for each effect identified as significant. Numerical evaluations are necessary to determine each effect for inhomogeneous cross-sections made of anisotropic material.
