Equity in healthcare in British Columbia is defined as the provision of services based on need rather than ability to pay and a separation of contributions to financing from the use of services. Physician and hospital services in Canada are financed mainly through general tax revenues, and there is a perception that this financing is progressive. This paper uses Gini coefficients, concentration...

Database outsourcing is becoming increasingly popular introducing a new paradigm, called database-as-a-service, where an encrypted client’s database is stored at an external service provider. Existing proposals for querying encrypted databases are based on the association, with each encrypted tuple, of additional indexing information obtained from the plaintext values of attributes that can be ...

We compare traditional portfolio selection strategies with stock market indexes in their standard and ESG versions. In addition to the comparison of 12 from different markets To portfolios we use conventional performance measures, results show that replacing versions does not detract terms Shape ratio other measures. general, there is no statistically significant difference between returns buil...

This paper reports research investigating the validity of using Pairwise Variability Indexes in research into the second language acquisition of speech rhythm. Findings determined that 1) expert native-speakers rate non-native speaker rhythm based on a common factor, and 2) part of that common factor can be accounted for by the use of vocalic pairwise variability. It was concluded that the PVI ...

In this paper we present an information retrieval system that indexes only site anchor text to verify the efficiency of reference information in a navigation retrieval task. We propose two relevancy measures to maximize limited information: reference consistency and specificity of word combination. Our results show that navigation retrieval with a site anchor text can pinpoint highly relevant d...

There are lots of validation indexes and techniques to study clustering results. Biclustering algorithms have been applied in Systems Biology, principally in DNA Microarray analysis, for the last years, with great success. Nowadays, there is a big set of biclustering algorithms each one based in different concepts, but there are few intercomparisons that measure their performance. We review and...

The accuracy of a diagnostic test is typically characterised using the receiver operating characteristic (ROC) curve. Summarising indexes such as the area under the ROC curve (AUC) are used to compare different tests as well as to measure the difference between two populations. Often additional information is available on some of the covariates which are known to influence the accuracy of such ...

Doppler echocardiography can provide insight into the diastolic properties of the left ventricle. The hemodynamic origins of the diastolic mitral flow velocity profile are reviewed and Doppler information is compared to other measures of left ventricular diastolic function. Factors affecting the mitral diastolic flow velocity in both normal populations and pathologic conditions are discussed an...

In this work, we introduce a method for constructing capacities using overlap indexes between the fuzzy sets which are generated from the inputs of the considered problem. We also use these capacities to aggregate information by means of the Choquet integral in a fuzzy rule-based classifier. We observe that with these capacities the obtained results are better than those obtained with other mea...
