This paper describes a logical machinery for computing decisions, where the available knowledge on the state of the world is described by a possibilistic propositional logic base (i.e., a collection of logical statements associated with qualitative certainty levels), and where the preferences of the user are also described by another possibilistic logic base whose formula weights are interprete...

This paper examines how sell-side equity research companies (brokerage houses) responded to the increased scrutiny of their equity research business regarding conflicts of interest driven by investment bank relationships. This scrutiny materialized in new regulations adopted by the Self-Regulatory Organizations NASD and NYSE, affecting all brokerage houses, and in the Global Settlement, affecti...

Previous studies have shown that a pessimistic explanatory style is a risk factor for illness, but the factors linking explanatory style and illness are unknown. One's characteristic response to poor health may mediate this relationship. Perhaps pessimistic individuals act helplessly in the face of their symptoms, thereby exacerbating disease. In the present study, we investigated this possibil...

Admissibility is a desired property of heuristic evaluation functions, because when these heuristics are used with complete search methods, such as A* and RBFS, they guarantee that an optimal solution will be found. Since every optimistic heuristic function is admissible, optimistic functions are widely used. We show, however, that with incomplete, real-time search, optimistic functions lose th...

In original Data Envelopment Analysis (DEA) models for measuring the relative efficiencies of a set of Decision Making Units (DMUs) using various inputs to produce various outputs are limited to crisp data. To deal with imprecise data, the notion of fuzziness has been introduced. this paper develops a procedure to measure the efficiencies of DMUs with fuzzy observations. The basic idea is to tr...

Decision making is usually based on the comparative evaluation of different op-tions by means of a decision criterion. Recently, the qualitative pessimistic criterionwas articulated in terms of a four-step argumentation process: i) to build argumentsin favor/against each option, ii) to compare and evaluate those arguments, iii) toassign a status for each option, and iv) to rank-...

Transactional Memory (TM) is a high-level programming abstraction for concurrency control that provides programmers with the illusion of atomically executing blocks of code, called transactions. TMs come in two categories, optimistic and pessimistic, where in the latter transactions never abort. While this simplifies the programming model, high-performing pessimistic TMs can be complex. In this...

Abstract This research is motivated by the high level of carbon emission due to dominance non-renewable energy consumption in use mix. study aims fill gaps previous support global programs reducing designing scenario through a shift (fuel oil) renewable (biofuel Asia Pacific for future periods, including 2023-2030. The basic foundation this result panel regression during period 2006-2021. Furth...
