Background Even though there are many patient organizations across Europe, their role in impacting health policy decisions and reforms has not been well documented. In line with this, the present study endeavours to fill this gap in the international literature. To this end, it aims to validate further a previously developed instrument (the Health Democracy Index - HDI) measuring patient organi...

information and knowledge management have become crucial to the development of a competitive edge on the market. this requires the gathering of complete and consistent information in an environment where companies are working increasingly with a vast network of partners. in this paper, we investigate the case of platforms on the tourism market selling trips in boxes thanks to a wide network of ...

Consistency techniques make a main flavour of most constraint satisfaction algorithms. Their goal is to remove as many as possible inconsistencies from the problem. Singleton consistency is a meta-consistency technique that reinforces other pure consistency techniques by their repeated invocation and thus it achieves even better domain pruning. The paper presents a new algorithm for singleton a...

In this paper, we consider First-order fuzzy differential equations with initial value conditions. The convergence, consistency and stability of difference method for approximating the solution of fuzzy differential equations involving generalized H-differentiability, are studied. Then the local truncation error is defined and sufficient conditions for convergence, consistency and stability of ...

Background & Aims: Fatigue Severity Scale (FSS), due to its simple and clinical nature, is frequently used to measure fatigue level in patients. Since fatigue is a common symptom in multiple sclerosis (MS) disorder, the present study aimed at evaluating the psychometric properties of the Persian version of FSS in patients with MS. Methods: This study was descriptive and of a validation type, in...

We introduce a novel and exciting research area: symmetrising levels of consistency to produce stronger forms of consistency and more efficient mechanisms for establishing them. We propose new levels of consistency for Constraint Satisfaction Problems (CSPs) incorporating the symmetry group of a CSP. We first define Sym(i, j)-consistency, show that even Sym(1,0)-consistency can prune usefully, ...
