conjunctive normal forms (PCNF) with existential variables should also be considered. ILP mostly uses learning with refinement … operators. To extend refinement operators to PCNF, we should first do so with substitutions. However, applying a classic … we define substitutions that specialize a given PCNF and a weakly complete downward refinement operator. Moreover, we …

Efficiency analyses in the health care sector are often criticised for not incorporating quality variables. The … definition of quality of primary health care has many aspects, and it is inevitably also a question of the patients’ perception … of the services received. This paper uses variables derived from patient evaluation surveys as measures of the quality of …

Quality is a dimension of water services that has been repeatedly omitted in the study of performance of water …-based and quality-adjusted indicators of technical efficiency for a sample of Spanish water utilities. The key assumptions are … that a lack of quality (bad quality) can be regarded as a bad output, and the existence of a trade-off between quantity and …

This paper analyzes the level of “technical” quality public schools and determines whether or not there are … discrepancies between this indicator and parents’ subjective perception of quality. A sample of public schools in Catalonia is … surveyed. The results show that parents correctly perceive the technical quality. Furthermore, there is a significant negative …

Cohesion and coupling metrics for a modular ontology provide an insight into the efficiency of the modularization … technique employed. Most of such metrics are either syntax based or do not account for ontology hierarchy. The authors propose … cohesion and coupling metrics with continuous scale of measurement for modular ontology via deducing the degree of dependence …
