The Eastern Atlantic and Mediterranean stock of Bluefin tuna Thunnus thynnus (BFTE) has long been considered overfished and at risk of collapse. Although ICCAT quotas for this stock have decreased considerably over the past years, uncertainty exists about the degree of catch beyond this quota. The extent of such catch is an important piece of information in stock assessment models as well as be...

The views and opinions expressed or implied in this article are those of the author (or authors) and do not necessarily reflect the position of the National Marine Fisheries Service, NOAA. The relationship between reproductive output and subsequent recruitment of new individuals is fundamental to population dynamics. In stock assessments, this relationship is typically quantified by using a spa...

Despite the abundant anecdotal evidence on the benefits of information technology (IT) outsourcing, whether the stock market reacts favorably to such a governance choice remains a puzzle. In line with the recent emphasis on a valuebased approach to evaluating firms, we adopt an event-study method to examine the market-impacting effects of IT outsourcing. Our analysis, based on a sample of 58 IT...

Biomass reconstructions to pre-assessment periods for commercially important and exploitable fish species are important tools for understanding long-term processes and fluctuation on stock and ecosystem level. For some stocks only fisheries statistics and fishery dependent data are available, for periods before surveys were conducted. The methods for the backward extension of the analytical ass...

Article history: Received 27 January 2015 Received in revised form 18 April 2015 Accepted 22 April 2015 Available online 20 May 2015 We assess the correlations between intelligence and financial development in 123 countries using data averages from 2000–2010. Cognitive human capital is measured in terms of IQ (Lynn and Vanhanen's IQ measures), cognitive ability (Rindermann's combination of psyc...

We formulate and simulation-test a spatial surplus production model that provides a basis with which to undertake multispecies, multi-area, stock assessment. Movement between areas is parameterized using a simple gravity model that includes a "residency" parameter that determines the degree of stock mixing among areas. The model is deliberately simple in order to (1) accommodate nontarget speci...
