The fate of the Brazilian Amazon is threatened by a new wave of frontier expansion following new infrastructure commitments worth US$40 bn from the federal Government. In a recent paper, alarming rates of deforestation and forest degradation have been predicted, which could be either pessimistic or optimistic depending on the scale of forest disturbance being considered. A more decisive prevent...

Recent research by Institute affiliates on the role of education in economic growth has produced two works which run counter to current thought. One study challenges standard measures of the value of schooling and concludes on the optimistic note that its full value has been underrated. The other study analyzes data on college enrollment over the past decade and concludes, on a pessimistic note...

The concept of a non-extreme-outcome-additive capacity (neo-additive capacity ) is introduced. Neo-additive capacities model optimistic and pessimistic attitudes towards uncertainty as observed in many experimental studies. Moreover, neo-additive capacities can be applied easily in economic problems, as we demonstrate by examples. This paper provides an axiomatisation of Choquet expected utilit...

Real Time Data Base Systems must insure temporal consistency as well as logical data consistency to exhibit correct behavior. The performance of these systems is measured as a percentage of transactions executed into their temporal restrictions. To achieve a good performance, Real Time Scheduling algorithms are needed. In this work a Real Time Scheduling algorithm based on a combination of both...

The paper aims to present an application of constraint programming techniques for project portfolio scheduling taking into account the imprecision in activity duration and cost. Data specification in the form of discrete α-cuts allows combining distinct and imprecise data, and implementing a constraint satisfaction problem with the use of constraint programming. Moreover using α-cuts, optimisti...

We study stochastic bilevel programs where the leader chooses a binary here-and-now decision and the follower responds with a continuous wait-and-see-decision. Using modern decision rule approximations, we construct lower bounds on an optimistic version and upper bounds on a pessimistic version of the leader’s problem. Both bounding problems are equivalent to explicit mixedinteger linear progra...

A lot of philosophers are pessimistic about conceivability evidence. They think it doesn't prove, or even go very far towards justifying, interesting modal conclusions. A number of other philosophers are optimistic; they think it does justify, and perhaps even establish beyond a reasonable doubt, that lots of interesting things are possible. Nothing very surprising there. What is slightly surpr...

This paper discusses the problem of cost allocation when players have different levels optimism based on two-stage minimum spanning tree game, and uses Choquet integral to calculate characteristic function fuzzy optimistic coalition pessimistic coalition. It is proved that subgame clear game also a convex game. Finally, an example used prove has dynamical instability solution.

Probabilistic and possibilistic models of sequential decision problems are known to possess good behavioral algorithmic properties. In this paper, the range under uncertainty that dynamically consistent, consequentialist allow for tree reduction is enlarged by considering a representation both probabilistic possibilistic. The corresponding utility functional expected highly likely states, an op...
