- Description: The concepts of editorial independence and public accountability are necessary in public broadcasting service as they help make a distinction between a public service broadcaster, a government and a commercial service broadcaster. This is because public service broadcasters are tasked with the responsibility of serving the interests of the general public. To do this, the above mentioned concepts have to be in place. This study examines these issues (editorial independence and public accountability) with reference to a case study of the editorial policies of the South African Broadcasting Corporation (SABC). Using public broadcasting theory, policy theory and qualitative research methods, the study examines the genesis of these editorial policies in 2003/2004 and how they provide the SABC with a means of balancing the tensions of editorial independence and public accountability. In analysing the SABC’s editorial policies, the study deals only with those policies whose principles are directly related to editorial independence and public accountability. Although some of these policies are found to be in line with public broadcasting service trends, others are found lacking. Various recommendations are made. The case study demonstrates the importance of an integrated and elaborated policy perspective in setting out how a public service broadcaster can manage editorial independence and public accountability. It also highlights the importance of using international ‘role models’ in ways that are appropriately adapted for the specific country concerned.

- Description: In the interests of maintaining end to end security, increasing volumes of information are being encrypted while in transit. Many organisations and users will make use of secure encrypted protocols for information interchange given an option. The very security that is provided by these transport protocols, such as IPSEC, HTTPS and SSH also acts against the security monitoring of an organisation’s traffic. Intrusion detection systems are no longer easily able to inspect the payload of encrypted protocols. Similarly these protocols can potentially be difficult for securi-ty and network administrators to debug, validate and analyse. This pa-per discusses the need for a means of a trusted third party being able to unpack encrypted data traversing a network and a proposes an ar-chitecture which would enable this to be achieved through the extrac-tion and sharing of the appropriate encipherment tokens, based on the assumption that an organisation has legitimate access to one side of a communication entering or exiting its network. This problem also has particular relevance to honey-net research and for investigators trying to perform real-time monitoring of an intruder which is making use of such a protected protocol. A proof of concept implementation of the proposed architecture is also discussed.

Using aspects of game theory for enhanced stakeholder participation perspectives in integrated water resource management: a Kat River Valley case study

- Description: South Africa is a water poor region and yet, like in many other developing countries, water resources are a valuable production input in socially important industries such as agriculture and mining (Nieuwoudt et al., 2004:162-182). With a mean annual rainfall and runoff of 502mm and 42mm (420m³ per hectare per annum) respectively, Briers and Powell (1993:1) speculate that water shortages will limit South Africa’s economic development in the twenty-first century. In response to the challenges of water resource scarcity and socio-economic inequalities, in 1997 the South African Department of Water Affairs and Forestry (DWAF), following international trends, formulated a National Water Policy (NWP) based on Integrated Water Resource Management (IWRM) principles (Palmer et al., 2003). The main objectives of the NWP (1997) are to protect national water resources from degradation, provide economically disadvantaged communities with access to water resources and promote economic development, through the devolution of water management responsibilities to locally established water institutions (NWP, 1997). The pursuit of these objectives requires a thorough investigation of biophysical, sociopolitical and economic characteristics of the demarcated water areas. For such an investigation to provide accurate and locally relevant results, broad stakeholder participation is of paramount importance. The thesis discusses economic measures required in pursuing enhanced stakeholder participation levels at local levels. A socio-economic survey investigation describing major participation trends against reported property rights and Willingness to Pay values was conducted in the Kat River Valley, Eastern Cape province. From the investigation, observed participation trends driven by economic interests were identified and used in recommendations proposed for the policy implementation process. Using game theoretic arguments as guidelines in soliciting cooperative behaviour in the use and consumption of common resources (Ostrom, 1990), the thesis proposes the introduction of water related public works projects as employment creating vehicles for individuals and communities targeted for economic empowerment and participation in the water policy. However, for sustainable stakeholder participation levels, it is argued that the employment positions created through the projects need to be designed in a manner that would encourage an evolution of long-term relationships between stakeholders and the water management institutions.

- Description: The structure of this study is a complex inter-relationship of a variety of sources in a theological work, namely, personal experience, African social and politico-economic context, philosophical reflection, wisdom traditions and Christian theology. These sources form a coherent inter-relationship which is foundational for an African theology of wisdom. The introduction gives an overview of my moral and theological formation. This is intended to provide a perspective through which the issue of moral orientation in African context has been approached. It is therefore entitled: Moral formation and the shaping of a theological mind. The first chapter answers the question: Why is Africa in need of a wisdom theology that addresses the issue of moral regeneration? This question is posed in the broader context of the current African Renaissance debates. The links between the Italian (European) and African Renaissance indicate that moral regeneration is a crucial part of the socio-political, intellectual and economic re-birth of Africa. This “socio-historical” source gives the context and urgency of a wisdom theology. It is therefore entitled: A contextual analysis: The European and African Renaissance. The second chapter re-asserts the rise of virtue ethics as an alternative ethical theory to the predominant deontological and utilitarian traditions. This is achieved through analysing Alisdair MacIntyre’s earlier work, After Virtue: A Study in Moral Theory (1981), set in the context of Iris Murdoch and Elizabeth Anscombe, the modern initiators of a virtue ethic. This “philosophical” source gives the theoretical framework that addresses the question of moral formation. It is therefore entitled: A philosophical analysis: The rise of virtue ethics as alternative ethical theory. The third chapter is devoted to two related “wisdom” themes: Firstly, the seven traditional virtues are briefly described highlighting the virtue of wisdom as foundational. Secondly, the idea of wisdom is further developed via three wisdom traditions, namely: wisdom in the Hellenistic, Judeo-Christian and African traditions. This “sapiential” source gives this African theology of wisdom its most important building blocks. This chapter is therefore entitled: A sapiential analysis: Wisdom as foundation for virtue ethics in Africa. The last chapter brings the previous sources together under a specific theological perspective. It draws on aspects of recent African theologians’ work, notably: Kwame Gyekye and Benezet Bujo who engage with and bring together Western and African theological traditions. I answer a pertinent question, “What does such a ‘theological’ perspective entail?” I draw on Scripture and its Trinitarian tradition to demonstrate how African wisdom, reinforced by the framework of virtue theory, and developed in the context of present-day Africa by an African student of theology, has the potential to contribute to the moral transformation of Africa. This more overt “theological” source is the distinctive Christian enterprise of an African wisdom theology. The chapter title is aligned with the overall title of this study: A theological analysis: Toward an African virtue ethics? To this end, this study achieves its attempt to construct an inter-related framework from which an African theology of wisdom may emerge.

- Description: Web Usage Mining (WUM) can be used to determine whether the information architecture of a web site is structured correctly. Existing WUM tools however, do not indicate which web usage mining algorithms are used or provide effective graphical visualisations of the results obtained. WUM techniques can be used to determine typical navigation patterns of the users of organisational web sites. An organisational web site can be described as a site which has a high level of content. The Computer Science & Information Systems (CS&IS) web site at the Nelson Mandela Metropolitan University (NMMU) is an example of such a web site. The process of combining WUM and information visualisation techniques in order to discover useful information about web usage patterns is called visual web mining. The goal of this research is to discuss the development of a WUM model and a prototype, called WebPatterns, which allows the user to effectively visualise web usage patterns of an organisational web site. This will facilitate determining whether the information architecture of the CS&IS web site is structured correctly. The WUM algorithms used in WebPatterns are association rule mining and sequence analysis. The purpose of association rule mining is to discover relationships between different web pages within a web site. Sequence analysis is used to determine the longest time ordered paths that satisfy a user specified minimum frequency. A radial tree layout is used in WebPatterns to visualise the static structure of the organisational web site. The structure of the web site is laid out radially, with the home page in the middle and other pages positioned in circles at various levels around it. Colour and other visual cues are used to show the results of the WUM algorithms. User testing was used to determine the effectiveness and usefulness of WebPatterns for visualising web usage patterns. The results of the user testing clearly show that the participants were highly satisfied with the visual design and information provided by WebPatterns. All the participants also indicated that they would like to use WebPatterns in the future. Analysis of the web usage patterns presented by WebPatterns was used to determine that the information architecture of the CS&IS web site can be restructured to better facilitate information retrieval. Changes to the CS&IS web site web were suggested, included placing embedded hyperlinks on the home page to the frequently accessed sections of the web site.

- Description: Wireless technologies have had an enormous impact on networking in re-cent years. It can create new business oppurtunities and allow users to communicate and share data in a new fashion. Wireless Networks de-crease installation costs, reduce the deployment time of a network and overcome physical barrier problems inherent in wiring. Unfortunately this flexibility comes at a price. The deployment, installation and setup of a WLAN is not a simple task and a number of factors need to be considered. Wireless Networks are notorious for being insecure due to signal spill, ad-hoc unauthorized access points and varying encryption strengths and standards. RF (Radio Frequency) interference and physical barriers sup-press a signal. In addition the channel frequencies each access point will be using in order to provide maximum roaming but minimum inter access point interference need to be considered. It is a complex balancing act to take these factors into account while still maintaining coverage, perfor-mance and security requirements. In this paper the benefits and feasibility of a model will be discussed that will enable the network administrator to visualize the coverage footprint of their wireless network when the above factors are taken into consideration. The program will be able to predict the strength, propagation and unwanted spill of signals which could compro-mise the security of an organisation prior to the deployment of a WLAN. In addition the model will provide functionality to visualize a signal from audit data once the WLAN is operational. The end result will be a program that can aid in the configuration, installation and management of a secure WLAN.

- Description: Wireless technologies have had an enormous impact on networking in re-cent years. It can create new business oppurtunities and allow users to communicate and share data in a new fashion. Wireless Networks de-crease installation costs, reduce the deployment time of a network and overcome physical barrier problems inherent in wiring. Unfortunately this flexibility comes at a price. The deployment, installation and setup of a WLAN is not a simple task and a number of factors need to be considered. Wireless Networks are notorious for being insecure due to signal spill, ad-hoc unauthorized access points and varying encryption strengths and standards. RF (Radio Frequency) interference and physical barriers sup-press a signal. In addition the channel frequencies each access point will be using in order to provide maximum roaming but minimum inter access point interference need to be considered. It is a complex balancing act to take these factors into account while still maintaining coverage, perfor-mance and security requirements. In this paper the benefits and feasibility of a model will be discussed that will enable the network administrator to visualize the coverage footprint of their wireless network when the above factors are taken into consideration. The program will be able to predict the strength, propagation and unwanted spill of signals which could compro-mise the security of an organisation prior to the deployment of a WLAN. In addition the model will provide functionality to visualize a signal from audit data once the WLAN is operational. The end result will be a program that can aid in the configuration, installation and management of a secure WLAN.

Writing, identity, and change : a narrative case study of the use of journals to promote reflexivity within a Drama Studies curriculum

- Description: The study adopts a case study examination of three student reflective joumals written about class and field based applied Drama experiences over one year. The journals were written as part of a curriculum outcome to develop reflective practice, for one Drama Honours paper (Educational Drama and Theatre) at Rhodes University Drama Department, South Africa. Based on a narrative inquiry approach, the study documents the changes in identity, discourse, and representation of self and other, which emerge through the journal writing process. The research analyses how identities are constructed through reflective writing practices, and how these identities might relate to the arguments for the development of reflexivity. The development of reflexivity is seen as integral to contemporary educational policies associated with lifelong learning, and the skills required of graduates in South Africa's emerging democracy. These policies centre on means of preparing students for a world characterised by change and instability, or what Barnett (2000) has termed a "supercomplex world". The research findings suggest that journal writing within a Drama Studies curriculum, allows students to construct subjectivities which support Barnett's claim that "the main pedagogical task in a university is not that of the transmission of knowledge but of promoting forms of human being appropriate to the conditions of supercomplexity" (Barnett, 2000b: 164). In addition, the development of different writing genres within a Drama Studies curriculum allows students to develop disciplinarily relevant ways of discussing and researching artistic processes and products. A reflective journal is a potential site for students to interrogate and construct emerging identities which enable them to negotiate diversity, thus preparing them for their lives beyond the university.

- Description: The XML Signature working group focuses on the canonicalisation of XML, and the syntax used to sign an XML document. This process focuses on the semantics intro-duced by the XML language itself, but ignores semantics which a particular applica-tion of XML may add. The Resource Description Framework (RDF) is a language for representing information about resources on the Web. RDF has a number of possi-ble serialisations, including an XML serialisation (RDF/XML), popularly used as the format for exchanging RDF data. In general, the order of statements in RDF is not important, and thus the order in which XML tags occur in RDF/XML can vary greatly whilst still preserving semantics. This paper examines some of the issues surround-ing the canonicalisation of RDF/XML and the signing of it, discussing nesting, node identifiers and the ordering of nodes. Existing RDF serialisation formats are consid-ered as case studies of partially canonical RDF formats.
