Libertäre politische Philosophie ist ihrem Selbstverständnis nach freiheitsradikal. Abgesehen von einem Minimalstaat, der das Leben und Eigentum seiner Bürger schützt, soll in allen Bereichen der Gesellschaft laissez-faire herrschen. Aber ist ein solches Gesellschaftsmodell tatsächlich im Namen der Freiheit zu verteidigen? Das ist die erste Leitfrage dieses Buches. Zu ihrer Beantwortung analysiert der Autor zunächst den Begriff der Freiheit und den Begriff eines moralischen Rechts, um danach den Versuch zu unternehmen, mit diesen Begriffen eine allein auf einem moralischen Recht auf Freiheit basierende libertäre politische Philosophie zu rekonstruieren. Die erste Leitfrage wird letztlich affirmativ beantwortet: Der Libertarismus ist die reinste Philosophie der Freiheit. Doch stellt sich noch eine zweite zentrale Frage: Gibt es gute Gründe, sich diese Philosophie auch zu eigen zu machen? Es werden drei Begründungsversuche des Libertarismus diskutiert und am Ende als nicht erfolgreich zurückgewiesen. Das Buch schließt mit einem Ausblick, in dem für die Aufnahme eines starken Rechts auf Freiheit in eine pluralistische politische Philosophie geworben wird.

The article argues that persons should be conceived as self-owners and entitled to acquire private property within justifiable property conventions because they should be able to live as project pursuers. This is the 'project pursuit argument'. It leads to a conception of self-ownership that is stringent, but weaker than standard libertarian notions of self-ownership, and to an understanding of private property as a convention that has to meet a sufficientarian threshold in order to be justifiable.

The International Energy Agency Technology Collaboration Programme for Ocean Energy Systems (OES) initiated the OES Wave Energy Conversion Modelling Task, which focused on the verification and validation of numerical models for simulating wave energy converters (WECs). The long-term goal is to assess the accuracy of and establish confidence in the use of numerical models used in design as well as power performance assessment of WECs. To establish this confidence, the authors used different existing computational modelling tools to simulate given tasks to identify uncertainties related to simulation methodologies: (i) linear potential flow methods; (ii) weakly nonlinear Froude–Krylov methods; and (iii) fully nonlinear methods (fully nonlinear potential flow and Navier–Stokes models). This article summarizes the code-to-code task and code-to-experiment task that have been performed so far in this project, with a focus on investigating the impact of different levels of nonlinearities in the numerical models. Two different WECs were studied and simulated. The first was a heaving semi-submerged sphere, where free-decay tests and both regular and irregular wave cases were investigated in a code-to-code comparison. The second case was a heaving float corresponding to a physical model tested in a wave tank. We considered radiation, diffraction, and regular wave cases and compared quantities, such as the WEC motion, power output and hydrodynamic loading. ; The Danish partners acknowledge the support from the Danish Energy Agency through project 374 64017-05197.
