- Description: The introduction of Web Services as a platform upon which applications can communicate has contributed a great deal towards the expansion of World Wide Web technologies. The Internet and computing technologies have been some of the factors that have contributed to the socio-economic improvement of urban and industrial areas. This research focuses on the application of Service-Oriented Architecture (SOA) and Web Services technologies in Information and Communication Technologies for Development (ICT4D) contexts. SOA is a style used to design distributed systems, and Web Services are some of the common realizations of the SOA. Web Services allow the exchange of data between two or more machines in a simple and standardized manner over the network. This has resulted in the augmentation of ways in which individuals in a society and in the world communicate. This research aims to develop a SOA-based system with services that are implemented as Web Services. The system is intended to support communication activities of Dwesa community members. The communication methods identified as the most commonly used in the Dwesa community are Short Message Services (SMSs) and voice calls. In this research we have identified further methods (i.e. Multimedia Message Service, Electronic mail and Instant Messaging) to augment communication activities in Dwesa. The developed system, therefore, exposes SMS Web Service, MMS Web Service, Email Web Service and IM Web Service that are consumed in machine-to-machine, machine-to-person and person-to-person types of communication. We have also implemented a one-stop communication shop, through a web portal which provides interfaces to the different communication modules. Elaborate functional and usability testing have also been undertaken to establish the viability and end-user acceptance of the system respectively. This research has provided the initial validation of the effectiveness of the SOA-based system in ICT4D contexts

The implementation of an integrated quality management system in Queenstown District schools: experiences from the Isibane Circuit

- Description: This study examines the experiences of the school management teams and educators of the Isibane Circuit in the Queenstown District, regarding the implementation of an Integrated Quality Management System (IQMS) policy at school level. Following an agreement reached in 2003 between the South African Education Department and the major teacher organisations in this country, the IQMS was scheduled to be implemented in public schools from 2004. Two major challenges are identified and explained: accountability and development of human resources, as well as contradictions between internal and external evaluations. The study also elaborates on the changes in the educational history from the apartheid system to the democratic system of education. Nine schools participated in the study (two secondary schools and seven primary schools). These schools were purposely selected due to the fact that they had started implementing the IQMS policy, which was the main criterion for selection. Semi-structured interviews were used to gather data from principals, Heads of Departments as well as post-level one educators concerning their experiences of the IQMS implementation. The findings indicated that while the IQMS policy was good on paper, it was extremely difficult to implement. Issues of honesty and trust were at the root of difficulties that made the IQMS implementation challenging. The participants‟ understanding of IQMS was that it was intended for the provision of quality education and development.
