Business Strategy and the Environment, EarlyView.ABSTRACT Environmental entrepreneurship and eco‐innovation, although cornerstones in the transition to a sustainable world, form a research nexus that remains largely understudied. We draw on the theory of complexity and the notion of cultural, temporal, and relational complexities to explain the process of eco‐innovation among environmental small ...

An analysis of fishing gear competition. Catalan fisheries as case studies
Scientia Marina, 2013 An asymmetric index was developed to measure the competition relationships among fishing fleets (or gears or métiers) in a multispecies fishery. This index can be used to measure the degree of dominance of each fleet and its level of independence from ...
