Oriented Approach

The service-oriented approach to performing distributed scientific research is potentially very powerful but is not yet widely used in many scientific fields. This is partly due to the technical difficulties involved in creating services and workflows and the inefficiency of many workflow systems with regard to handling large datasets. We present the Styx Grid Service, a simple system that wraps command-line programs and allows them to be run over the Internet exactly as if they were local programs. Styx Grid Services are very easy to create and use and can be composed into powerful workflows with simple shell scripts or more sophisticated graphical tools. An important feature of the system is that data can be streamed directly from service to service, significantly increasing the efficiency of workflows that use large data volumes. The status and progress of Styx Grid Services can be monitored asynchronously using a mechanism that places very few demands on firewalls. We show how Styx Grid Services can interoperate with with Web Services and WS-Resources using suitable adapters.

Storage Grid is a new model for deploying and managing the heterogeneous, dynamic, large-scale, and geographically distributed storage resources. This chapter discusses the challenges and solutions involved in building a Service Oriented Storage (SOS) Grid. By wrapping the diverse storage resources into atomic Grid services and federating multiple atomic Grid services into composite services, the SOS Grid can tackle the heterogeneity and interoperability. Peer-to-peer philosophy and techniques are employed in the SOS Grid to eliminate the system bottleneck and single point of failure of the traditional centralized or hierarchical Grid architecture, while providing dynamicity and scalability. Because Grid service is not designed for critical and real-time applications, the SOS Grid adopts Grid service to glue the distributed and heterogeneous storage resources, while using binary code to transfer data. The proposed methods strike a good balance among the heterogeneity, interoperability, scalability and performance of the SOS Grid.

As data driven decision-making using business intelligence and analytics (BI&A) becomes standard in companies, the importance of mitigating the accompanying growth in costs increases. Research shows that the increasing transparency of individual BI&A artefacts such as reports or analytic applications is necessary, but in practice and implementation lags behind. This article addresses the status quo for three types of stakeholders: users, developers, and managers. The results show where a strong need for action exists and this article identifies challenges for further research. These findings indicate that managers see BI&A cost accounting as having a high potential benefit - and believe the degree of implementation to be higher than other stakeholder types do. The authors identified comprehensibility as an important factor for user acceptance of BI&A cost accounting systems; this could be supported by a service-oriented approach. The authors conclude that BI&A professionals have to consider these different perceptions and their implications in order to gain traction for BI&A cost accounting.

Although the life sciences curriculum asks for the inclusion of indigenous knowledge systems in the classroom, it is either done very superficially by only providing an example or two, or ignored completely. This mixed-methods study (with emphasis on the qualitative inquiry) on the status of indigenous knowledge in the life sciences classroom in Gauteng and Limpopo, once again echoed what Rogan and Grayston (2003) reported: the South African curriculum process focuses too much on the what (the curriculum itself) at the expense of the how (the implementation of the curriculum). Although the progressive curriculum makes it clear that indigenous knowledge should be addressed, it provides very little guidance to teachers on how this should be done. Two problems are highlighted in this article: teachers’ lack of pedagogical content knowledge in addressing indigenous knowledge systems, as well as their poor understanding of the nature of science. A teacher’s social responsibility also entails making learners aware of the cultural and practical value of indigenous knowledge, and stimulating learners’ interest in scientific fields such as ethnobotany and chemotaxonomy.
