T PROTESTANT theologian Otto Dibelius made a prophetic statement when, in the title of a well-known book, he referred to the 20th century as "the century of the Church." Although treatises on the Church had appeared sporadically since the 14th century, ecclesiology had not yet assumed the central position in Catholic theology that it has enjoyed in our own century. The foundation of Theological...

Beginning with a short historical sketch, electrodynamic energy harvesters with focus on vibration generators and volumes below 1 dm are reviewed. The current challenges to generate up to several milliwatts of power from practically relevant flows and vibrations are addressed, and the variety of available solutions is sketched. Sixty-seven different harvester concepts from more than 130 publica...

The combination of a randomly fluctuating environment and dispersal of biological organisms calls into question the adequacy of traditional bioeconomic models, the vast majority of which are both deterministic and aspatial. Perhaps for this reason, economists have been largely silent on recent policy debates surrounding fisheries management in a complex environment. In particular, much of the s...

Human harvests can unwittingly drive evolution on morphology and life history, and these selective effects may be detrimental to the management of natural resources. Although theory suggests that harvest refuges, as sources of unselected animals, could buffer the effects of human exploitation on wild populations, few studies have assessed their efficiency. We analyzed records from >7000 trophy ...

This process involves a number of meetings where the status of waterfowl is reviewed by the agencies responsible for setting hunting regulations. In addition, the U.S. Fish & Wildlife Service (USFWS) publishes proposed regulations in the Federal Register to allow public comment....
