- Description: The concept of ‘development journalism’ has, over time, become possessed by demons of all sorts of confusion. If we want to wrest any useful principles from the concept, it is important that we exorcise the demons it has come to be associated with, not least the demon of the postcolonial state’s blatant interference in the practice of journalism. This ‘demonisation’ of the concept is partly suggested by Shah’s observation that ‘development journalism’, central to many discussions of mass communication and development in the Third World, needs to be reconceptualised because deliberations about its validity and usefulness have been bogged down in arguments structured by Western notions of press freedom. The debate has diverted attention from important questions about how journalism can contribute to participatory democracy, security, peace, and other humanistic values (Shah 1996: 143). In this paper, therefore, I will, firstly, discuss the conceptual basis of development journalism. I will rely heavily on development communication theorising, which informs most of the discussions about development journalism. I want to demonstrate the historical ‘moments’ through which the concept has passed and, by so doing, point out the more redeemable features of the concept. Secondly, I will discuss the relevance of the development journalism paradigm to public service broadcasting. In conclusion, I will draw out some principles of development journalism and demonstrate how these can be implemented within the context of public service broadcasting.

- Description: This paper describes the use of a MetaGeek WiSpy dongle in conjunction with custom developed client-server software for the accurate identication of Wireless nodes within an organisation. The MetaGeek WiSpy dongle together with the custom developed software allow for the determination of the positions of Wi-Fi transceivers to within a few meters, which can be helpful in reducing the area for physical searches in the event of rogue units. This paper describes the tool and methodology for a site survey as a component that can be used in organisations wishing to audit their environments for wireless networks. The tool produced from this project, the WiSpy Signal Source Mapping Tool, is a three part application based on a client-server architecture. One part interfaces with a low cost 2.4 GHz spectrum analyser, another stores the data collected from all the spectrum analysers and the last part interprets the data to provide a graphical overview of the Wi-Fi network being analysed. The location of the spectrum analysers are entered as GPS points, and the tool can interface with a GPS device to automatically update its geographical location. The graphical representation of the 2.4 GHz spectrum populated with Wi-Fi devices (Wi-Fi network) provided a fairly accurate method in locating and tracking 2.4 GHz devices. Accuracy of the WiSpy Signal Source Mapping Tool is hindered by obstructions or interferences within the area or non line of sight.
