Resource rent in aquaculture
(Chapter; Bokkapittel, 2019)Resource rent in aquaculture (RRA) is any payment to a farm and site owner, on land or sea, in excess of the costs needed to bring that farm into production. For analytic and policy purposes it may be useful to distinguish among different types of RRA. Three types will be discussed: rent associated with the classical economists Ricardo (1821) and Faustmann (1849), as well as oligopoly rent from ... -
The Potential Usefulness of Virtual Reality Systems for Athletes: A Short SWOT Analysis
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-05)Virtual reality (VR) systems (Neumann et al., 2017), which are currently receiving considerable attention from athletes, create a two- or three-dimensional environment in the form of emulated pictures and/or video-recordings where in addition to being mentally present, the athlete even often feels like he/she is there physically as well. As she/he interacts with and/or reacts to this environment, ... -
