I would like to thank Mat Warren for his assistance in providing the Ethics section and Rod Clarke for his assistance in providing the section on Semiotics. Our first paper is entitled - A Method for Reverse Engineering of Use Case Realizations in UML and is provided by Dragan Bojic and Dusan Velasevic from the University of Belgrade. This paper provides a method for recovering elements of the UM model including relationships between use cases and class roles. Timothy Shin, Ming-Chi lee, The Sheng Huang and Lawrence Deng, from Tamking University Taiwan provide the next paper entitled - Assessing Software Quality Through Visualised Cohesion Metrics. This paper presents cohesion metrics which aid in cohesion strength and which can be used in CASE tools to aid software engineers. Our next paper is entitled - Synthesising Structuration and Institutional Theory: Three Cases is presented by Jason Thatcher, Florida State University, Mark Strite, University of Wisconsin, Manolis Diakourakis and David Kuhlmeier, Florida State University. This paper develops a conceptual framework that links institutions and organizations social structures to the use and understanding of information technology in the public sector.

John Weckert, Charles Sturt University presents our next paper - IT Research and Development: Should there be Control?. This paper looks at the underlying issues surrounding the responsibilities of professional researchers, in particular, those who work in artificial intelligence. Mark Williams, Edith Cowan University presents our next paper - Ethics in Research. This paper examines the question of ethics in research through the reporting of a a series of self dialogues. Our next section concerns semiotics. An overview entitled Studies in Organisational Semiotics: An Introduction is presented by Rod Clarke, University of Wollongong. Peter Andersen, University of Aalborg present the next paper entitled Maritime Work and Communication. Thi paper presents findings from a study examining the development instrument interfaces for use in shipping. Our next paper is Organisational Semiosis: Integration and Separation between System Features and Work Practices, Rod Clarke, University of Wollongong. This paper looks at the application of systemic semiotics to the relationship between system features and work practices. Clarissa De Souza, Cecilia Da Cuhna, Raquel Prates and Simone Barbosa, Catholic University of Rio de Janeiro present our next paper - Echoes of Semiotically-Based Design in the Development and Testing of a Workflow System. This paper looks at the design and implementation of a web based workflow system, Qualitas. Our next paper is Aspects of Text Mining from Computational Semiotics to Systemic Functional Hypertexts by Alexander Mehler, University of Trier. This paper looks at the introduction of text linkage in natural language text mining. Our final paper is presented by Rob Shields, Carleton University and is entitled The New Knowledge Speak: The Implications of Contested Definitions of Knowledge and Information.
