The past ten years have witnessed substantial improvements in programming methodology. This advance, carried out under the banner of “structured programming,” has led to programs that are more reliable and easier to comprehend; yet the results are not entirely satisfactory. My purpose in the present paper is to propose another motto that may be appropriate for the next decade, as we attempt to ...

To achieve sharing and reuse for sustainable development, documents are semantically interrelated by ontologies, specified formally using the specification language Casl. The specification of properties for relations in the system’s ontology is used to check invariant properties during change management. Documents are structured for fine-grained management of variants for essentially the “same”...

The purpose of this paper is to report the possible reasons for premature abandonment by lowliterate users during online searches. Previous evidence suggests that low-literate web users abandon their online searches early believing that the information they were looking for should be in the section they were at, thinking that they have either found it or that the information was unavailable. Th...

More consumers in developing regions are using information systems (IS) to facilitate their work and increase productivity. This may imply that more low-literate populations in society are becoming the next billion IS consumers. Yet, how to adapt past IS literature in high-literate context to guide IS designs for low-literate consumers remains a gap. The current study, therefore, aims to apply ...

In this thesis we introduce and evolve the paradigm of theme-based literate programming (TBLP). TBLP enhances on the literate programming (LP) model, as invented by Donald Knuth in the early 1980s. TBLP provides a generic model that copes with current and future software development methodologies and practices. We show that through this extended chunk and processing model, XML-based support, an...
