The paper presents a novel approach to collaborative design of educational software with students, one that asks the participants for the formation and use of fictional characters – design alter egos – as a means towards eliciting requirements and design ideas. In order to evaluate the suggested approach, we conducted 12 collaborative design sessions with the participation of 54 undergraduate u...

This study evaluates the feasibility of using the grass species Rendlia altera, Monocymbium ceresiiforme, Cynodon dactylon, and amendments (compost and lime) for the phytostabilisation of soils contaminated by Cu in the province of Katanga (Democratic Republic of Congo). Species were grown on control and Cu-contaminated plots (artificially contaminated with 2,500 mg kg(-1) Cu) unamended (NA), a...

FPGA users are constantly looking for ways to differentiate their products in the market place and in doing so they define new systems with new requirements. The new requirements usually are increased functionality, higher processing performance, low power consumption, customizable capabilities, and reprogrammability. To achieve these requirements, the proven methodology is to double the FPGA d...

This article explores strategic conceptions within the alter-globalisation movement in Ireland. Based on action research carried out within the left-libertarian (“Grassroots’) wing of the movement, it notes imbalances in participation in a very intensive form of political activity, and asks how activists understand winning. It finds substantial congruence between organisational practice and lon...

Facultative, partially migratory animals provide a contemporary window into the evolution of migration, offering rare opportunities to examine the life-history trade-offs associated with migration. For the first time, to our knowledge, we describe the nature of these trade-offs, using a lek-breeding tropical bird, the white-ruffed manakin (Corapipo altera). Previous evidence indicated that weat...
