This article analyses the challenges for the strategies and practices of transformational development in a changing context. This reflection is based on contributions received during the process of dialogues and regional consultations, realised from August 2012 until March 2014, of the ACT Alliance, an international coalition of churches and faith-based organisations (FBOs) working in the areas of humanitarian response, development and advocacy. The main processes that affect the changing development context are addressed, such as the ongoing globalisation as well as (...) the consequences, mainly regarding the shrinking space for civil society. It discusses the concepts of human development and of transformational development, based on a people-centred development vision, a human rights-based approach and advocacy, which addresses the root causes and effects of poverty, inequality and injustice. Transformational development practices, from Latin America, are presented and analysed. The article concludes that the changing development context also offers opportunities, especially regarding regional and global alliances of FBOs, civil society organisations and of social movements.

A comparison of nineteen taxa of teleost fishes suggests the gradual acquisition of systems of upper jaw protrusion in the course of fish evolution. However, in view of the loss of protrusion in several groups of advanced teleosts the biomechanicsof protrusile jaws are analysed based on the hydrodynamics of suction feeding. Calculations show that protrusion may reduce the energy otherwise spent in a feeding act to get the predator's mouth as near to the prey in the same time with about (...) 80%. Other generalized advantages and disadvantages of upper jaw protrusion are explained. Detailed ecological data to calculate the balance between pros and cons of jaw protrusion of a particular species in its habitat are still lacking. There is no incompatibility between presence and disappearance of protrusile jaws in fish and current neo-darwinistic theories of evolution. (shrink)

Contemplating the catastrophic course of the Nazi Revolution we may well find it all too easy to see nothing in the spectacle but the nether darkness made visible; and if we are advised that it is not merely permissible but highly advisable to learn from the enemy, we may be tempted to think that whatever the Nazi war-machine has to teach the strategist and the technician, the political history of Germany in the last decade, and in particular the political ideology (...) that has imposed itself upon the German mind with such apparent thoroughness, can yield only the negative lesson of a warning, by displaying upon the world-wide stage the doomful consequences of wrong principles ruthlessly pushed to their extreme. But it is certainly an error to deny that nothing of more positive value has emerged out of the revolutionary cauldron: and indeed it would be more than strange, where such whole-hearted energies of mind are being enlisted in the evil cause of Nazism, if none of its votaries had ever stumbled for a time into wisdom.
