There is global interest in recovering locally extirpated carnivore species. Successful efforts to recover Louisiana black bear in Louisiana have prompted interest in recovery throughout the species' historical range. We evaluated support for three potential black bear recovery strategies prior to public release of a black bear conservation and management plan for eastern Texas, United States. ...

In this paper, we analyze momentum strategies that are based on reward-risk stock selection criteria in contrast to ordinary momentum strategies based on a cumulative return criterion. Reward-risk stock selection criteria include the standard Sharpe ratio with variance as a risk measure, and alternative reward-risk ratios with the expected shortfall as a risk measure. We investigate momentum st...

The novelty of the study consists in applying eWOM communications and Technology Acceptance Model (TAM) in the context of online communities to explain user’s intention toward innovative product / service. Our findings indicated that eWOM effect is a key antecedent of perceived ease of use, perceived usefulness, and perceived enjoyment. The recommender’s levels of expertise, seeker’s levels of ...

Since the advent of evolution strategies many attempts have been done to improve the mutation operator [7]. The first enhancement could be seen in the introduction of a flexible step size. As a logical consequence later n step sizes, one per variable, were used. Highest flexibility is achieved with the correlated mutation but also quadratic growth of the number of strategy parameters [8]. A new...

In order to reduce the risk of complete failure, research managers often adopt a parallel strategy by simultaneously funding several R&D activities and several research teams within each activity. The parallel strategy requires the allocation of an available budget to a number of R&D activities, the determination of the number of research teams within each activity and the amount of funding the...

The Besley-Coate model of representative democracy has the problem of multiple equilibria (Besley-Coate, 1997). We show that requiring the Besley-Coate political equilibria to be iteratively undominated at the voting stage re nes the set of (pure strategy) political equilibrium outcomes only for those cases where at least four candidates stand for election. This note complements the results of ...

While some argue that innovation is inhibited by installed base, this paper suggests that it is critical to service innovation. In particular, the installed base of devices and infrastructure is an important element for improved diffusion and higher acceptance of services. It brings forward a nuanced view of installed base and reports a case study of Swedish National Road Administration’s strat...
