The purpose of this study is to investigate the relationship between technological capabilities and firm performance. We divide technological capabilities into two types – exploitation, which refers to refinement, production and execution, and exploration, which refers to searching, flexibility, and innovation. Based on a sample of 302 small and medium-sized manufacturing firms in Japan, our an...

Scarcity of water resources and huge costs of establishing new hydraulic installations necessitate optimal exploitation from existing reservoirs. Sustainable management and efficient exploitation from existing finite water resources are important factors in water resource management, particularly in the periods of water insufficiency and in dry regions, and on account of competitive allocations...

The Isostichopus fuscus fishery in Mexico was heavily exploited until 1994, when it was closed due to overfishing. However, no information existed on the status of the populations. The fishery was evaluated through an age structured simulation model, and according to our analysis of the stock, the fishery can be feasible and sustainable as long as fishing mortality and age of first catch are op...

Linear operators in equations describing physical problems on a symmetric domain often are also equivariant, which means that they commute with its symmetries, i.e., with the group of orthogonal transformations which leave the domain invariant. Under suitable dis-cretizations the resulting system matrices are also equivariant. Methods for exploiting this equivariance in the numerical solution o...

In a mixed strategy, game-theoretical scenario mimicking the behaviour of fishing vessels competing for a limited renewable resource, agents following either a Collective Intelligence or a purely selfish strategy quickly outperform fully-cooperative teams as well as agents not planning for future action by acting randomly. The stable balance between fully selfish agents and the Collective Intel...

Age-specific arrest rates for the United States at the crime peak of the late 1980s and early 90s are compared to those for 2010. Three key features are explored; (1) The disproportionate decline in adolescent offending; (2) The decline in this age-effect up to age 40; (3) Offenders aged in their 40s who in 2010 offended at higher rates than offenders of that age at crime’s peak. The first two ...

There has recently been an increased demand in bone age estimation (BAE) of living individuals and human remains in legal medicine applications. A severe drawback of established BAE techniques based on X-ray images is radiation exposure, since many countries prohibit scanning involving ionizing radiation without diagnostic reasons. We propose a completely automated method for BAE based on volum...

Abstract. Over the past decades, range managers have devoted extensive efforts to conserve and restore rangelands and sustain their exploitation but these efforts are more focused on the classic sciences and the exploiters' knowledge and experience have been neglected in the process. Therefore, current study was done to deal with the prioritizing and comparing factors affecting rangeland exploi...

Significant decline in abundance of greenland halibut Reinhardtius hippoglossoides matsuurae the North-West Pacific is one reasons for development methods this species age determination using different age-recording structures. The study based on recommendations Northwest Atlantic Fisheries Organization (NAFO) and International Council Exploration Sea (ICES). Underestimation found records scale...
