One problem with the XP development process is its fragility. If developers use the XP techniques in an unintended way or not at all, the XP process is likely to break down: The misused techniques affect the other XP techniques in a negative way, breaking the whole process. We believe that it is possible to stabilize the XP process using specialized artifacts to reify the XP techniques. We disc...

In the last decade, the debate about the ontological foundations of reified temporal logics (RTLs) has been relatively quiet, even though we think some problems still exist. In this paper, we identify some of these problems and propose (partial) solutions to them in a FOL framework. States are here characterized (at the syntactic level) as truth-makers of propositions—they reify true propositio...

Current literature abounds with evidence of how developed economies utilize information and communication technologies (ICT) for socio-economic development. On the other hand, less developed economies, including those in Africa continue to struggle with the use and diffusion of ICT. Such research, often under the theme of the digital divide, usually treats Africa as a monolith. Not much evidenc...

This paper argues that many extensions of Dung’s framework incorporating relations additional to binary attacks, are best viewed as abstractions of human rather than computational models of reasoning and debate. The paper then discusses how these additional relations may be reified into object level knowledge, thus enabling reconstruction of the extended framework as a Dung framework, and provi...

In my learning disabilities class each year, a student does a presentation on remediating reading comprehension problems. To prepare for the presentation, students read the most recent textbooks and articles that describe strategies to improve reading comprehension. At some point during the presentation, the student will say something like, "The ability to identify the main idea is crucial for ...

Recent developments in reification of ER schemata include automatic generation of webbased database administration systems [1,2]. These systems enforce the schema cardinality constraints, but, beyond unsatisfiable schemata, this feature may create unreachable instances. We prove sound and complete characterisations of schemata whose instances satisfy suitable reachability properties; these theo...

ly, reflection refers to the capability of a system to reason about and act upon itself. More specifically, a reflective system is one that provides a representation of its own behavior, which is amenable to inspection and adaptation, and is causally connected to the underlying behavior it describes. "Causally-connected" means that changes made to the self-representation are immediately mirrore...

Sustainable development has brought with it a broader consideration of the role of different stakeholders. Considerable scholarship has gone into demonstrating that purpose and perspective matter, and that stakeholder groupings based on these can be much more complex than basic social or economic variables might suggest. Yet an examination of the stakeholder analysis tools in the management lit...
