The diffusion of the use of the learning virtual environments presents a great potential for the development of an application which meet the necessities in the education area. In view of the importance of a more dynamic application and that can adapt itself continuously to the students’ necessities, the “U-ALS” (Ubiquitous Adapted Learning System) was proposed and developed. This system was bu...

The present RDF is opaque in reusing the descriptions in ready-made metadata repositories. To enhance reusability of descriptions in RDF/XML, we need a unit for packaging a set of descriptions on a semantic schema level. And, we may need a new rule to handle a composite unit of not linearfold but link-based or graph data structure, and serialize it to reuse.

The international safety standard, IEC 61508, presents several challenges to its users who are often not familiar either with safety engineering and management or with introducing a new standard. This paper first explores the background to the difficulties that companies experience in using the standard. It then discusses the difficulties that the standard poses, in the context of how a company...

R esearch on health inequalities among older adults is hampered by the lack of a suitable measure of poverty in this age group. 2 Grundy and Holt have recommended the development of a measure for studying health inequalities in older people, which combines basic living conditions and social customs with household resources. The 1999 poverty and social exclusion omnibus survey (PSEOS) yields dat...

This Research Brief, the second in our series on immigrant children, draws on new results from Census 2000 data to examine differences in the poverty rates between children in immigrant families and children in native-born families. The brief reports results for the official poverty measure, but also for two alternatives to the official measure. Most notably, the official poverty measure does n...

One type of deflationism about metaphysical modality suggests that it can be analysed strictly in terms of linguistic or conceptual content and that there is nothing particularly metaphysical about modality. Scott Soames is explicitly opposed to this trend. However, a detailed study of Soames’s own account of modality reveals that it has striking similarities with the deflationary account. In t...

Where does the aspiration to retard human ageing fit in the 'big picture' of medical necessities and the requirements of just healthcare? Is there a duty to retard human ageing? And if so, how much should we invest in the basic science that studies the biology of ageing and could lead to interventions that modify the biological processes of human ageing? I consider two prominent accounts of equ...

One of the sources of heterogeneity of ontologies is that different ontologies have different necessities of modelling. This paper presents a biphase method to deal with these different necessities. Phase I of the method models how to model the ontology, obtaining a meta-model. Such meta-model can be expressed in LBIR, a formal and declarative language that has been specifically designed for th...

This meta-synthesis presents the results of qualitative studies on puerperal perception concerning woman’s care in the post-partum period. Four databases were researched using keywords such as “postnatal care” (or) “postpartum period”, (and) “care”, “women”, “perception”, “qualitative research”, “women’s health services”, “community health services”, “allied health personnel”, “primary health c...
