Software Migration

This paper investigates the contribution of stakeholder collaboration during an open source software migration using a case study. The case study is based on the Presidential National Commission, a South African government department that migrated from proprietary software to open source software in 2007. The organization was one of the few that migrated to open source software as part of a South African government initiative. The case study consisted of semi-structured interviews with the participants involved in the migration. The interviews centered on the contribution of stakeholder collaboration during the software migration using a boundary critique. The results suggest that stakeholder collaboration can contribute to open source software migration. From a managerial perspective, business leaders must understand the value of stakeholder collaboration in open source software migration. Boundary critique can be an important tool for achieving broader collaboration of stakeholders.

Special Case

Abstract In software architecture the dynamic structure of a software system can be described in terms of components and connectors and expressed through the use of Architectural Description Languages (ADLs). We present jADL, a new ADL, designed for the creation and validation of dynamic and mobile architectures. It, also, aims to help towards the process of “unifying” the definition and implementation of an architecture in a way that the final result is consistent with the architecture in terms of both functional requirements and quality attributes. In this paper, we examine into details the definition and expression of jADL’s architectural elements; components, connectors, ports, roles and behaviour describing statements – attach, detach, config, bind. The attributes of synchronicity and multiplicity concerning the connections between architectural elements are presented. A special case of connections is presented – the bind statement and the construction of composite architectural elements. Also, a case study of the client-server dynamic model in jADL is presented and the possibilities of jADL for dynamic reconfiguration are explored.

Development Risks

While there are many studies conducted on software risk during the last two decades, very few have been published on software risk management practice in IT industry. In this paper we explore industry practice in the management of software development risks in outsourced software migration projects. We take the vendor perspective, post contract finalization. We conducted an online survey of 145 software projects executed by global IT vendors with process maturity of CMM Level 5. Based on this we built a statistical model relating software risk management factors with project outcome. An embedded case study of a large software migration project executed for a fortune 500 company was undertaken to check whether the model agrees with actual industry practice. The best practices and experiences from the project are also shared.

The 1960S

AbstractUsing interviews with former militants and previously unpublished documents, this article traces the genesis and internal dynamics of the Ejército Revolucionario del Pueblo (People's Revolutionary Army, ERP) in El Salvador during the early years of its existence (1970–6). This period was marked by the inability of the ERP to maintain internal coherence or any consensus on revolutionary strategy, which led to a series of splits and internal fights over control of the organisation. The evidence marshalled in this case study sheds new light on the origins of the armed Salvadorean Left and thus contributes to a wider understanding of the processes of formation and internal dynamics of armed left-wing groups that emerged from the 1960s onwards in Latin America.

Abstract Culture shapes our basic sensory experience of the world. This is particularly striking in the study of religion and psychosis, where we and others have shown that cultural context determines both the structure and content of hallucination-like events. The cultural shaping of hallucinations may provide a rich case-study for linking cultural learning with emerging prediction-based models of perception.
