Structural change in organisations is stressful for staff and the managers who must implement it. Most change programs use employee communication techniques to support change directions set by senior executive decision makers-dominant coalitions. This research used a single case study to explain the context and management discourses of a major re-structure of an Australian Federal Government agency, the former Civil Aviation Authority (CAA), during the early 1990s. A content analysis examined the use of keywords in management discourses that argued the need for change. The keywords represented the two major change discourses: micro-economic reform and aviation safety regulation. A critical discourse analysis investigated the dominant coalition's discourse strategies to justify change. Content and process communication theories, and the role of framing in organisational change, were used to explain how employees may have reacted to change directions. The research found that change directions were framed as an economic imperative that clashed with a traditional organisational culture that emphasised the primacy of aviation safety. It found that mixed messages by the two principal members of the dominant coalition who drove change exacerbated the clash. The results suggest a need for further analysis of management discourses used to inform employees about structural change, especially in organisations that have legislative responsibilities. Further analysis of change messages framed by dominant coalitions could lead to a deeper understanding ofhow they affect employees and the change process.

Text in English / This research project, within the context of security risk management in general and aviation security in particular, aimed to explore the impact of the application of international and local air cargo security regulations on South Africa, with specific reference to the regulations of the International Civil Aviation Organisation (ICAO), as well as the European Union (EU) and the United States of America (USA). In South Africa, since the early 2000s, the South African Civil Aviation Authority (SACAA) has been the lead agency for dealing with and managing the needs for air cargo security. This oversight by SACAA culminated in 2009 with the promulgation of the SACAA Regulation commonly known as Part 108. Accordingly the primary research focus was on the impact Part 108 has had on the air cargo industry in South Africa. In addition, it compared the South African regulations with those of the USA and EU regulations; explored the compliance of the various roleplayers; sought to understand the enforcement of the regulations; and examined the effectiveness of the available security and screening methods. Furthermore, the research attempted to determine whether these regulations had any effect on preventing or deterring crime in the air cargo sector. / Criminology and Security Science / M. Tech.
