Entrepreneurial Spawning and Firm Characteristics [PDF]
Management Science, 2011 We analyze the implications of the decision to spawn or to retain a new product for the nature and evolution of the firm. In our model, a new product is spawned if the fit between the product and its parent firm organization is not adequate. We focus on the impact of the firm's history of spawning decisions on firm characteristics such as size, focus ...

Management applications of genetic structure of anadromous sturgeon populations in the Lower Danube River (LDR), Romania [PDF]
Scientific Annals of the Danube Delta Institute, 2013 During the last decades, the over-exploitation of sturgeon stocks for caviar production simultaneously with severe habitat deteriorations has led to drastic declines in the natural populations of the Danube River. As a result of (i) decrease of sturgeon

Advanced Science, EarlyView.Oocytes play crucial roles in maintaining ovarian fate in adult gonochoristic fish. Targeted oocyte ablation with aromatase inhibition triggers the activation of surviving germline stem cells and the transdifferentiation of somatic cells from granoulosa/theca to Sertoli/Leydig lineages, inducing a complete and functional female‐to‐male sex reversal ...

Sound from spawning cod at their spawning grounds [PDF]
ICES Journal of Marine Science, 1999 Sound was recorded at five stations at and near the main spawning grounds of the northeast Arctic cod (Gadus morhua L.) off the Lofoten Islands, Norway. Recordings were carried out during April 1997 when large numbers of cod aggregated to spawn, and were repeated in September when the cod were no longer spawning and, in fact, most had emigrated.
