This article proposes a rereading of the timeline of the British Black Arts Movement, and offers early work by the Pakistan-born British artist, writer, and editor Rasheed Araeen as possible starting points for reading the work of a new generation of artists who emerged in the early 1980s. Making Waves draws attention to a work by Araeen, For Oluwale, which commemorated the racist killing by police officers of David Oluwale, a Nigerian vagrant persecuted in Leeds, England, during the mid-1960s, leading to his death in 1969. While proposing a radical new timeline, the article also concedes that "beginnings are notoriously unstable things."

New Waves in Ethics brings together the leading future figures in ethics broadly construed, with essays ranging from meta-ethics and normative ethics to applied ethics and political philosophy. Topics include new work on experimental philosophy, feminism, and global justice, incorporating perspectives informed from historical and contemporary approaches alike. An ideal collection for anyone interested in the most important debates in ethics and political philosophy, as well as those with an interest in the latest significant contributions from the leading new generation of philosophers working in ethics.

Abstract: Lift-based Wave Energy Converters (WECs) have a number of attractive features, including the potential for unidirectional rotation, simplifying power take-off and reduction in wave loads by reducing generation of circulation, increasing survivability. The common assumption of small body, small amplitude response, together with the Haskinds Relationship is used to determine the optimum motion for a lift-based WEC to maximise power capture. It is shown that whilst for a 2D hydrofoil in deep water the optimum motion is circular, the optimum motion for a finite-width hydrofoil is generally elliptical due to differences in the hydrodynamic damping coefficients associated with the vertical and horizontal motions of the hydrofoil. It is shown that more circular hydrofoil motion can be achieved by utilising the elliptical motion of the water particles in shallow water. This occurs because the increased horizontal water particle motion in shallow water results in an increase in the wave-induced lift force associated with horizontal fluid particle motions, and thus a reduction in the optimum amplitude of motion in this direction. Preliminary calculations suggest that for a 30 metre wide hydrofoil in wave periods of about 10 seconds, the ideal water depth (where the optimum hydrofoil motion is circular) occurs at around 25 metres, which is a highly utilisable water depth. Other advantages of deployment in shallower water include an improvement in the alignment of the waves parallel to the hydrofoil and a reduction in the structural task associated with reacting against the seabed. ; This work was produced as part of the LiftWEC Project.

Abstract. In past decades theoretical studies have been carried out with the double aim of improving knowledge of the main characteristics of the rogue wave and of attempting to predict its sudden appearance. We have tried to generate rogue waves in a water wave tank, using a symmetric spectrum (Akhmediev et al., 2011a) as input on the wave maker. The next step has been to apply a theoretical model to the amplitude envelope of these waves. After some considerations we agreed the best model to be an analog of the Ginzburg–Landau equation.

Macht durch Disziplin! Macht durch Gemeinschaft! Macht durch Handeln! Wie entsteht Faschismus? Ein junger Lehrer entschließt sich zu einem ungewöhnlichen Experiment. Er möchte seinen Schülern beweisen, dass Anfälligkeit für faschistoides Handeln und Denken nicht etwas ist, das nur andere Menschen betrifft – Faschismus ist hier mitten unter uns und in jedem von uns. Doch die "Bewegung", die er auslöst, droht ihn und sein Vorhaben zu überrollen: Das Experiment gerät außer Kontrolle. Morton Rhues Klassiker DIE WELLE beschreibt eindringlich und gegenwartsbezogen, wie leicht Menschen verführt, manipuliert und instrumentalisiert werden können. Der Roman basiert auf wahren Begebenheiten an einer Highschool im kalifornischen Palo Alto.
