The computer as a Trojan Horse

Abstract This paper reports on a study of boys in an Australian secondary school who were under achieving in school mathematics. The subjects were asked to develop computing software to teach fellow students about aspects of Ancient Egyptian mathematics. The paper reports four example case studies of the experience of the subjects during the course of the intervention. The paper examines the use of computing software development as a vehicle for the incidental learning of mathematical technique and for changes in attitude towards mathematics. Four different mathematical activities are reported in the case studies with a screen-dump of the subjects work included as an illustrative example.

Application of the CALPHAD approach to Mg-alloys design

The CALPHAD method can be applied as a tool for both alloy development and process guideline determination. In this study, two Mg alloys were designed, their process parameters derived and, using the CALPHAD method, the final results simulated. These results were later confirmed using tangible experimental methods. It was found that γ$\gamma$- Mg₁₇Al₁₂ precipitates along the grain boundaries (GB), Mg₂Sn forms both along the GB and as fine precipitates in the α$\alpha$-Mg matrix and the addition of Ce mishmetal (MM) leads to the formation of elongated Al- rare earth (RE) precipitates along the GB. The microstructural stability at 200 ^°C is high, showing no decrease in microhardness for 32 days. It is shown that the CALPHAD method considerably reduces the effort of alloy design and that the reliability of the results is high.     

Global and task effects in information-seeking among software engineers

Information-seeking strategies were explored in software engineers. A complex interaction of task and geographic differences was revealed. There is a general tendency across software engineers to favor non-social sources, such as documentation, for tasks where the goal is to seek factual information. More social sources are preferred when seeking information to diagnostic, problem-solving questions. Within this effect, some geographic variations assert themselves in a way that might partly be interpreted in terms of national cultural differences in Individualism vs. Collectivism. Implications of geographic differences in information-seeking for collaboration within global software development teams are discussed.

Guidelines for the incremental identification of aspects in requirements specifications

The desired principle of separation of concerns in software development can be jeopardized by the so-called crosscutting concerns, which tend to be scattered over (and tangled with) the functionality of the modular units of a system. The correct identification of such concerns (and their encapsulation into separate artifacts) is thereby considered a way to improve software understanding and evolution. Pursuing a proper management of concerns from the requirements engineering stage can greatly benefit the entire software life-cycle. In this paper, we propose conceptual guidelines on how to perform the identification of crosscutting concerns in the process of building requirements specifications. We argue that the identification must be carried out in an incremental way, to encapsulate apart the crosscutting concerns even if they have not emerged completely yet.
