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...

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...

In this paper we consider the inclusion properties for upper and lower approximation of union and intersection of sets for both pessimistic and optimistic mult igranulations. We find that two inclusions for pessimistic cases are actually equalities. For other six cases we provide examples to show that actually the proper inclusions hold true. On the approximation of classifications a theorem wa...

This paper studies free-riding incentives on common environmental resources in an incomplete information repeated game where abatements are perishable and perfect substitutes. Two contrasting types of perfect Bayesian equilibria emerge: For high discount factors, or low discount factors but ‘‘pessimistic’’ prior beliefs, the inclusion of incomplete information has no impact on the pattern of ab...

The present study applies explanatory style theory and the content analysis of verbatim explanation (CAVE) technique toward examining the leadership behaviors and effectiveness of key Civil War generals. The results of our study suggest that relatively optimistic explanatory styles may lead to aggressiveness and risk taking while relatively pessimistic explanatory styles may lead to passivity a...

Highly optimistic explanatory style (HOES) and highly pessimistic explanatory style (HPES) are two maladaptive ways to explain the world and may have roots in attachment insecurity. The current study aims to explore the effects of security priming - activating supportive representations of attachment security - on ameliorating these maladaptive explanatory styles. 57 participants with HOES and ...

We have studied the relationship between optimism, pessimism and entrepreneurial attitudes among university undergraduate students (n = 206). We used the revised Life Orientation Test [1] as a measure of optimism and pessimism and we hypothesized that technological potential entrepreneurs are more optimistic and less pessimistic than non-potential entrepreneurs. Our results show a main effect o...
