Drawing from the foundation of positive psychology and the recently emerging positive organizational behavior, two studies (N = 1,032 and N = 232) test hypotheses on the impact that the selected positive psychological resource capacities of hope, optimism, and resilience have on desired work-related employee outcomes. These outcomes include performance (self-reported in Study 1 and organization...

This article examines the effects of the leadership style of the principal, “transformational leadership and transactional leadership”, along with teachers’ job satisfaction on schools’ organizational health. Specifically speaking, it investigates to what extent the variations in school health can be related to the principal’s leadership style and teachers’ job satisfaction. To this end, a Like...

background the purpose of this study was to investigate the relationship between emotional intelligence and personality traits of nurses with patient’s satisfaction of nursing services in the hospitals of jundishapur university of ahvaz. material and methods the sample of this study was consisted of 352 nurses in the hospitals of jundishapur university of ahvaz, selected through simple random s...

We consider a semi-dynamic setting for the Temporal Constraint Satisfaction Problem, where we are requested to maintain the path-consistency of a network under a sequence of insertions of new (further) constraints between pairs of variables. We show how to maintain path-consistent a network in the deened setting in O(nR 3) amortized time on a sequence of (n 2) insertions, where n is the number ...

We report on an empirical evaluation of a new probabilistic heuristic for constructive search in constraint satisfaction problems. The heuristic is based on the estimation of solution probability. We show empirically that this heuristic is more accurate than related heuristics, and reduces the number of consistency checks and backtracks in constructive search by up to several orders of magnitud...

The Constraint Satisfaction Problem (CSP) is one of the areas of artiicial intelligence where a signiicant amount of problem classiication and complexity analysis has co-occurred. For a large class of scheduling problems, described in a CSP notation, we propose a hypergraph as an underlying structure. We show that using causal theories, based on the nature of constraints, can lead to a signiica...

We present a parallel solver for numerical constraint satisfaction problems (NCSPs) that can scale on a number of cores. Our proposed method runs worker solvers on the available cores and simultaneously the workers cooperate for the search space distribution and balancing. In the experiments, we attained up to 119-fold speedup using 256 cores of a parallel computer.

PURPOSE The study aims to examine job satisfaction of migrant live-in home care workers who provide care to frail older adults and to examine the extent to which quality of relationships between the care provider and care recipient and workplace characteristics is associated with job satisfaction.  DESIGN AND METHODS A convenience sample that included 335 dyads of Philippine workers and their...

This paper provides a technique for solving general constraint satisfaction problems (CSPs) with continuous variables. Constraints are represented by a hierarchical binary decomposition of the space of feasible values. We propose algorithms for pathand higher degrees of consistency based on logical operations defined on this representation and demonstrate that the algorithms terminate in polyno...
