  • Description: The restructuring of higher education through incorporations and mergers has attracted a lot of attention over the past few years in South Africa. These incorporations and mergers have displaced institutions of higher education and positioned them in new organisational homes, thus subjecting faculties, schools and departments to a process of relocation, new knowledge acquisition, identity change and meaning-making processes. The merger has resulted in three types of universities; i.e. traditional universities, comprehensive universities and universities of technology. The introduction of the comprehensive university as a new institutional type has brought with it questions about the idea of the university and the purpose of higher education in general. Mergers in particular have initiated conversations about sense-making and meaning during change. Amidst all this, people within the merging institution have been confronted with a new organisation with which they have to identify. At universities in particular, questions about academic identity and organisational identity have become unavoidable. The boundaries that gave definition to a university have been (re)moved. The structure of the university, as it was known, has changed. Hence, in the newly merged NMMU, academics are in the process of internalising and giving meaning to the new organisational values and norms of a comprehensive university. Needless to say, the challenges facing the newly merged NMMU are cultural, structural and geographic. Bringing together different institutional and personal cultures involves a human dimension that needs to be nurtured by trying to form a coherent and cohesive organisation that is created from culturally diverse and uncomplementary institutions. Another challenge is bringing together different organisational structures, systems and programmes that are informed by different institutional cultures. Furthermore, the challenge of having multiple campuses that are geographically separated exacerbates the situation. Along with all these challenges, the NMMU has the task of constructing an integrated institutional identity through organisational forms and programme models that will embody the multiple functions that are typical of a comprehensive university. The aim of the current study was to explore how the meanings that academics assign to the notion of a comprehensive university are instrumental in constructing an organisational identity; describing in detail how at the NMMU academics make meaning of the comprehensive university and how that meaning-making process influences the construction of an organisational identity; and formulating recommendations based on the qualitative findings and quantitative results of the research. In an effort to achieve the aim alluded to above, this study employed the mixed methods approach that used a sequential, exploratory, transformative design. The complexity of the study was such that it required to be investigated through qualitative and quantitative analytical methods in order to confirm, triangulate and obtain a holistic picture of the situation under investigation. The sample for the qualitative interviews consisted of thirteen purposefully selected academics from all levels at the NMMU. The interviews were transcribed and coded into themes, categories and sub-categories. These themes were then developed and translated into statements for the questionnaire that was administered randomly to all NMMU academics. A total of 108 academics responded to the questionnaire. The responses to the questionnaire were analysed using the SPSS programme. The findings and results of the study revealed that there was a fairly common understanding of the term comprehensive university among academics. However, the details about its procedures appeared to be the privileged ownership of management. This situation mitigated the necessity for a sense-making process that would allow for negotiation, modification and alteration of already held assumptions. A pertinent concern amongst academics was the neglect of the ‘human factor’ during the change process. The management style also came under scrutiny, especially in terms of the facilitation and mediation of change. There was a consensus on the call for cohesion and unity that was believed to be one of the main features that would make the construction of the NMMU organisational identity possible. The vision, mission and values of the NMMU were believed to be central to the creation of cohesion and unity, which would subsequently result in the birth of an organisational culture that could inform the organisational identity of the NMMU. Strategies to actualise and realise the organisational identity were proposed by participants. Notwithstanding, the impact of the merger was identified as having a major influence in shaping the organisational identity of the NMMU.

  • Description: This treatise was undertaken to critically analyse the new general anti avoidance rules (new GAAR) as set out in sections 80A to 80L of the Income Tax Act1. A discussion on the difference between tax evasion and tax avoidance was performed in the first chapter. The goals of this treatise were then set out. An analysis of the requirements for the application of the new GAAR was performed in the second chapter. The courts have historically reviewed the circumstances surrounding an arrangement when determining whether tax avoidance has occurred. The new GAAR requires the individual steps of an arrangement to be reviewed in isolation. Secondly, the courts have historically held that the purpose test, when determining the taxpayer‘s purpose, was subjective. The wording of the new GAAR indicates that this test is now objective. Thirdly, the courts have historically viewed the abnormality of an arrangement based of the surrounding circumstances. The wording of the new GAAR requires an objective view of the arrangement. An analysis of the secondary provisions contained in sections 80I, 80B and 80J of the new GAAR was performed in the third chapter. With regards to section 80B, it was submitted that the Commissioner should issue an Interpretation Note detailing all the methods ―he deems appropriate.

  • Description: This study investigates the extent to which South African short-term insurance companies manage climate change risk, as evidenced in their annual and sustainability reporting. The study context takes into account the fact that the world’s climate has been changing at a more accelerated rate since the early 1970s, causing disasters that have negatively affected world economies in the last ten years. Insurers, due to their huge financial resource base, long history of spurring innovation around risk and encouraging loss-reducing behaviour as well as high levels of vulnerability, have been identified as one industry that could lead societies in finding solutions to climate change risk. A key element of such a corporate resolve involves taking a leadership position which makes business sense for insurers. As such, this research analyses how innovative solutions to change-related problems could result in reduced exposure to climate change in line with corporate triple bottom line objectives. Based on a purposive sampling of short-term insurance companies operating in the South African market during the 2007 financial year, the study uses the companies’ annual and sustainability reports in order to critically assess evidence of climate change-related performance. The assessment is undertaken against the best practice indicators of climate change risk management, as defined by Ceres – a global researcher on climate change management in the business context. The data analysis is largely qualitative, consisting of a narrative presentation of the results and a conceptual application of the results to the triple bottom line which forms the theoretical framework of this study. The study finds that the South African short-term insurers were generally not living up to the climate change management ideals, in comparison to their multinational counterparts. For the South African short-term insurers, corporate strategic product innovation and planning was insignificant. Also negligible was board involvement, as well as CEO involvement, though in at least one case of the 4 local short-term insurance, there was evidence of extensive CEO involvement in climate change risk management. On the whole, these findings represent a lapse in corporate governance inasmuch as climate change risk management is concerned. Local short-term insurers generally performed well in the area of public disclosure, with their scores ranging from insignificant to extensive. In contrast, multinational short-term insurers’ performance with regard to climate change risk intervention ranged from insignificant tointegrated, across the five governance areas of board oversight, management execution, public disclosure, emissions accounting and strategic planning. As such, the study broadly recommends that short-term insurers in South Africa should make climate change part of their overall risk management strategies in order for them to remain competitive in an environment of increased climate change-related risk. More specifically, the research project recommends that the local insurers should proactively lead climate change mitigation measures through, for instance, investing in clean energy projects and incentivising their clients’ participation in the carbon market to prepare themselves for possible regulatory restrictions after the Copenhagen climate change conference planned for December 2009. This study also challenges insurers to help communities and as well as other businesses in their value chain to reduce their negative impacts on the world’s climate and to be more resilient against disasters which may arise from the high levels of greenhouse gases already in the atmosphere. Further, it recommends that insurers should create internal board and executive level climate change-related structures, as these will facilitate the integration of the proposed initiatives into their overall sustainability strategies. Above all, the study recommends that insurers should enhance the reporting of their climate change-related risk, opportunities and initiatives to improve their integrity.

  • Description: The transformation of all spheres of South African government to a more effective and efficient administration became a priority after the election of the country's first democratic government in April 1994. An important aspect of South Africa's democratisation was the promise by the new government to improve the lives of the people of this country, and provide a better life for all the citizens of South Africa. One of the most effective ways of achieving this goal is generally accepted to be the proper management and strengthening of the local government sphere. Local government is the sphere of government that is closest to the people, and generally the performance of National Government is assessed through the performance of municipalities. In strengthening local government, various pieces of legislation were developed since 1994 to ensure that the objectives of Section 152 of the Constitution are achieved. As a result of these imperatives, the Department of Provincial and Local Government introduced a White Paper on Local Government on 9 March 1998, with a vision of working towards a new developmental local government system. Various statutes emanated from this strategic framework, such as the Local Government: Municipal Structures Act No. 117 of 1998, the Local Government: Municipal Systems Act No. 32 of 2000 and the Local Government: Municipal Finance Management Act No. 56 of 2003. These legislative enactments endeavour to ensure that the local sphere of government is managed more strategically than previously, and is responsive to the needs of communities. Municipalities are expected to deliver efficient and affordable services to the local communities, and failure to do so could result in the recent spate of violent protest that has been recently experienced in various parts of the country. In order to measure the extent of service delivery to the communities, and to assess whether the objectives named in the municipality's Integrated Development Plan (IDP) document are being achieved, municipalities are compelled to implement performance management for all members of staff, political office bearers and service providers, in terms of the Municipal Systems Act No. 32 of 2000. This thesis therefore looks at challenges faced by the Senior Management (i.e. Section 57 employees, Directors and Assistant Directors) in the implementation of performance management within the Nelson Mandela Bay Municipality, during the first five years of their term in office (i.e. Senior Management appointed after 6 December 2000 local government elections), and recommending performance management steps as well as performance management model that can be used to cascade performance management amongst all levels of staff. This thesis begins by introducing the subject of performance management, briefly discussing the demarcation of the research, the research method utilised, the historical background of performance management, as well as the current status of performance management within the municipality. The introduction of the topic is followed by a theoretical overview of the subject of performance management. This is followed by the discussion of the research methodology followed when conducting this research study. The findings are discussed in detail after the research methodology, giving a synopsis of what the interviewees disclosed during the interview process. The last chapter provides a brief discussion of the findings, and discusses the recommended performance management steps and performance management model, that can be used by the municipality to cascade performance amongst all members of staff.

  • Description: Education policies remain a contested terrain in both the social and political environments. They are not neutral instruments and are used both to maintain the existing social order and also to promote varying kinds of change or mobility. The South African Schools Act, 1996 (Act 84 of 1996) hereafter SASA, which is the source of all policies that regulate school issues in South Africa promotes democratic methods of school governing and education provisioning that favours the previously disadvantaged groups. The NNSSF is one of the policies of SASA that makes schooling accessible to the poor through school fee exemptions while attempting to close the gap between the rich and the poor through differentiated school funding created according to researched poverty levels and standardized target lists. This has been designed to fulfil one of the essential human rights of man- education that has been entrenched in the Bill of Rights of the Republic of South Africa Constitution, 1996 (Act 108 of 1996) hereafter, Constitution. Thus, the study’s objective is to evaluate the implementation of the NNSSF policy in public schools focussing on school fee exemptions. The extent to which poor parents and learners are given school fee exemptions as they are supposed to according to the policy will be indicators of whether the NNSSF is justly or unjustly implemented in public schools. Learners are the recipients of the right to education. Parents are given the responsibility to fund the education of their children. However, for poor parents to fulfil that they need advice and assistance from the teachers and SGBs to be able to access the school fee exemptions while they have a right to just administrative action and to human dignity in dealing with them. SGBs and teachers have to create a favourable environment for the just implementation of the NNSSF by advising and xiii assisting deserving parents and learners to access school fee exemptions so that the right to education is fulfilled. The duty of in loco parentis and acting in the best interest of the child enforce teachers to do everything possible to ensure that learners access education. EDOs are supposed to guide, monitor and supervise the implementation of the policy while legal bodies should assist parents and learners to demand their right when it is violated through litigation. The study used the method of survey which is quantitative and interviews which are qualitative. Questionnaires and interview schedules were tools used to collect data that was analysed through statistical methods and represented in the form of tables and pie-charts. Various significant findings were made that had a bearing on the implementation of the NNSSF policy in public schools, most important to note is that some learners who have the right to education are aware of this right but do not know how to ensure that it is not violated. Parents are not given the opportunity to decide whether school fees should be charged in their schools. Above that they are not given the advice they need to be able to access school fee exemptions. Some teachers think that by advising and assisting learners and parents they will be buying cheap popularity- showing ignorance. EDOs do not know how schools implement the NNSSF, they are not involved in anyway. Thus the study views the implementation of NNSSF policy in public schools as unjust and recommends that SGBs and teachers need to be educated, guided and monitored by the EDOs on the policy and its implementation. They in turn will have to educate parents and learners so that they are able to access school fee exemptions thereby receiving education – their right.

  • Description: This study originates from experiences I had as supervisor of the mentoring programme for first year students in the Faculty of Pharmacy, at Rhodes University. Our mentoring programme is a strategy for first year students – specifically those from previously disadvantaged backgrounds – to succeed at Rhodes University. Using an ontological meta-theory - critical realism - as my analytical lens, discourse as my unit of analysis, and Invitational Learning Theory as a theoretical tool I developed a model of mentoring based on Bhaskar’s transformational model (1993). This model illustrates the relationship between structure, culture and agency. Whilst developing this model I focussed on determining how mentors construct mentoring, and how mentoring facilitates access to a Community of Practice (CoP). Mentoring involves providing a shared space that is safe, that the mentor and mentee feel comfortable in, and that supports and challenges both the mentor and the mentee. It is a reciprocal, developmental relationship for both the mentor and the mentee that deals with issues that the mentee deems as ‘real’. Mentoring is a process, not an outcome. The mentoring strategies that the mentors employed changed as the mentors mentored. Mentors help mentees by using structures and mechanisms that worked for them, and/or by helping mentees access these structures and mechanisms. Mentoring facilitates access to a CoP by providing opportunities for engagement. This involves sharing of experiences and knowledge, and promoting discussion. The mentor helps the mentee move from being a peripheral member of the CoP to becoming a main member, i.e., becoming active, learning with and from others within the CoP. CoPs develop social capital and knowledge management. My research suggests that the knowledge, skills and attitude developed by the mentors within this study may be transferable to other aspects in Pharmacy.

  • Description: This study aims to provide a critique of Baroque performance practice, with specific reference to the organ Preludes and Fugues of Johann Sebastian Bach. Drawing from the extensive body of literature pertaining to Bach’s keyboard music, a number of relevant issues are explored in so far as these may provide understanding of the manner in which the organ Preludes and Fugues should be performed today. These include: • The notion of Bach’s ‘generic’ keyboard works. Were the generic keyboard works as a whole intended to be performed on more than one keyboard instrument? The instrumental designations given by Bach in these works are a valuable source of information in answering this question. • The type of organ that was known to J.S. Bach and typical registration used in the Baroque, called the plenum. • Identification of the grey area that persists in the interpretation of Bach’s organ works with regard to registration, tempo, rhythm, articulation, phrasing, fingering and ornamentation. This study also engages with the current authenticity debate in musical performance as seen from the modernist and postmodernist points of view. The modernist ideal of authenticity is to “re-create” or “reconstruct” performances of Bach’s music with as much accuracy as the evidence of historical musicologists can provide. For the postmodernist, however, authenticity lies in embracing the human element of contingency in musical performance, along with a thorough grounding of such performance in historical evidence. In aligning itself with the postmodernist point of view, this study ultimately argues that we cannot learn everything there is to know about Baroque performance practice from books. Instead, in addition to historical evidence, we draw much of our understanding in this regard from our innate or tacit levels of knowing. In this regard the scholar of Bach’s organ works can draw valuable lessons from the levels of tacit knowledge of leading organ pedagogues and performers on the subject of Baroque performance practice.

  • Description: The growth of forced migration populations - i.e. the movement of people within and across national boarders as a result of conflicts, disasters, and development policies and projects - has been a defining feature of the twentieth century and will no doubt remain with us well into the twenty-first century (Rutinwa, 2001: 13). Literature searches suggest that the ‘refugee’ constitutes the most powerful label within the forced migration discourse. Published calculations regarding the number of refugees in the world at the end of 2008, range between 15.2 million (UNHCR, 2009: 2) and 13.6 million (World Refugee Survey, 2009: 33). The refugee experience of a small representative population of these figures namely, the Zimbabwean refugees living within the Central Methodist Church (CMC) or Central Methodist Mission (CMM) refugee community, in Johannesburg city centre is the concern of this treatise. From the perspective of the conflict management scholar, the informal and formal conflict management strategies adopted among and between the CMM refugees, have been studied. Analysis of existing literature, interviews conducted with the refugees, as well as hours of experience within the refugee community, substantiate the descriptive study that follows. Guided by the grounded theory approach, research findings have emerged out of the descriptions. The research findings in turn have founded the development of the recommendations that appear in the conclusion to the treatise.

  • Description: This thesis takes the form of an enquiry into the development of the ―generic contours (Bakhtin 4) for the narration of torture in South Africa during apartheid and its aftermath. The enquiry focusses on the ethical determinations that underlie the conventions of this genre. My theoretical framework uses Adam Zachary Newton‘s conceptualization of narrative ethics to supplement Paul Ricoeur‘s writings on narrative identity and the ethical intention, thus facilitating the transfer of Ricoeur‘s abstract philosophy to the realm of literary criticism. Part I presents torture as a disruption of narrative identity and a defamiliarization of the intersubjective encounter. The existence of torture narratives thus attests to the critical role of narration in the reconstruction of the tortured person‘s identity and the re-establishment of benign frameworks of intersubjective communication. Literature‘s potential to act as a laboratory for the testing of the limitations of narrative identity and the resilience of ethical mores suggests that the fictional representation of torture also has an important role to play in this attempt at rehabilitation. Part II takes the form of a comparative analysis of non-fictional and fictional accounts of torture originating from apartheid South Africa. This shows that the ethical determinations underlying the narration of torture in South Africa range from intersubjective estrangement to a ―solicitude of reciprocity (Bourgeois 109). However, because the majority of these texts used the presentation of human rights abuses to galvanize international opposition to apartheid, the scope for experimentation was limited by the political exigencies of the time. Part III examines the stylistic and generic shifts in the narration of torture that accompanied South Africa‘s transition to democracy. It suggests that the discursive dominance of the Truth and Reconciliation Commission replaced the fruitful—in literary terms—dialogue between authoritarianism and resistance that characterized the apartheid era with a monologic grand narrative of emotional catharsis, reconciliation and nation building. It also suggests that the ―truth-and-reconciliation genre of writing (Quayson 754) that shaped the literary milieu of the post-TRC period be seen in terms of a resurgence of the apartheid–era paradigms for the narration of human rights abuses that were repressed during the initial phase of democratic transition. By framing the TRC as a catalyst for individual journeys of self-discovery, these novels raise important questions about what it means to be a part of the ―new South Africa. In contrast to the majority of apartheid era literature, the novels of the post-TRC period privilege the literary prerogative over the political, and thus bring to fruition the experimental potential of the previous paradigm. In doing so, they not only go beyond solicitude to achieve an ―authentic reciprocity in exchange (Ricoeur, Oneself 191), but also initiate a process of long-awaited literary expansion, in which authors look beyond the limits of apartheid and begin to critically engage with the region‘s pre-apartheid history and its post-apartheid present.

  • Description: Anton van Wouw : the smaller works is, as its title implies, concerned with the generally lesser-known smaller works of Dutch-born sculptor, Anton van Wouw. Using the measure of "half life-size and smaller" as a guideline, author Alexander Duffey provides a comprehensive and well-illustrated overview of the many full-length small sculptures, busts, relief panels and maquettes produced by Van Wouw between 1881 (nine years prior to his arrival in South Africa at the age of 28) and 1940. Naturalistically sculpted and generally cast in bronze, these smaller works are wide-ranging in their subject matter, depicting innocuous, commonplace scenes alongside aspects of Afrikaner history, representations of Boer and British leaders, and so-called "native studies" (p 11).

  • Description: The role of the South African National Defence Force (SANDF) has changed considerably in the last decade. The emphasis has moved from protecting the country's borders to peacekeeping duties in Central Africa and even further North. Communications between the peacekeeping missions and the military bases back in South Africa is vital to ensure the success of these missions. Currently use is made of satellite as well as High Frequency (HF) communications. There are drawbacks associated with these technologies (high cost and low data rates/interference respectively). Successful long distance ionospheric propagation in the low Very High Frequency (VHF) range will complement the existing infrastructure and enhance the success rate of these missions. This thesis presents a feasibility study to determine under what ionospheric conditions such low VHF communications will be possible. The International Reference Ionosphere (IRI) was used to generate ionospheric data for the reflection point(s) of the signal. The peak height of the ionospheric F2 layer (hmF2) was used to calculate the required antenna elevation angle. Once the elevation angle is known it is possible to calculate the required F2 layer critical frequency (foF2). The required foF2 value was calculated by assuming a Maximum Useable Frequency (MUF) of 20% higher than the planned operational frequency. It was determined that single hop propagation is possible during the daytime if the smoothed sunspot number (SSN) exceeds 15. The most challenging requirement for successful single hop propagation is the need of an antenna height of 23 m. For rapid deployment and semi-mobile operations within a jungle environment it may prove to be a formidable obstacle.

  • Description: The Kouga Riparian Rehabilitation Project (KRRP) is seen as a pilot rehabilitation project in the Kouga region that is heavily invaded with Acacia mearnsii along the riparian zones of many mountain streams. Clearing of these black wattles and re-planting of indigenous vegetation are imperative to rehabilitation efforts. In this context, two invaded catchments were identified - the Baviaans and the Heuningnes. The aim of this research is to characterise the effects that the woody alien invasive Acacia mearnsii has had on the river channel morphology of the Baviaans and Heuningnes Rivers. A desktop and initial field analysis of the relevant study area catchments was completed. This was followed by a comparison of the channel morphology of the various study channel reaches using fixed channel transects. Ecological resource quality objectives (RQOs) for river rehabilitation from a fluvial geomorphological viewpoint were then established. A long-term monitoring protocol to assess whether or not these RQOs will be achieved was recommended. Follow-up channel transects were measured post wattle clearance in the Baviaans and short-term (<2yrs) changes in channel form were described. Differences in terms of the effect of Acacia mearnsii on channel form were then interpreted by direct comparison and through statistical analysis. Results indicate a number of significant differences between those channels impacted by black wattle infestation and those channels seen as unimpacted and natural. Short-term changes (<2yrs) that occurred within the study period post Baviaans wattle clearance were shown to be minimal for channel form as well as for bed material. The lack of any clear relationship or explanation between channel form and other channel controls suggests vegetation as the primary control. Vegetation, specifically the invasive alien vegetation, is the key controlling variable acting on channel form in the two study catchments.

  • Description: Certain prominent environmental theorists have accounted for and/or addressed our unmitigated environmentally damaging behavior in cognitive terms, related to a common (misplaced) belief that economic development and technological advancement, among other contemporary processes, will solve our environmental problems. However, I argue that they have not given due consideration to the complex (predominantly non-cognitive/non-conscious) discursive constitution of the individual, and thus seem to adhere to a Kantian notion of autonomy that overlooks such non-cognitive factors. Focusing on this non-cognitive aspect of discursive constitution, I ascribe our ecological apathy mainly to the fact that we have been discursively constituted as docile bodies and prostrate subjects. Further, I argue that, because this process of discursive constitution is primarily non-cognitive, any attempts to remedy our ecological apathy at a cognitive level alone will not be completely effective. Consequently, I propose that a more effective way of fostering pro-environmental dispositions may be for individuals to engage in an ethic/culture of the self that is not exclusively conceptual in orientation, and which is centered on the practice of a counter-discourse that does not constitute the individual as docile and prostrate nor negate the individual’s dependence on the environment. Alternatively, in order to engender pro-environmental civilizational change, it may be necessary to operate within the discursive parameters of dominant/popular institutions, in order to incrementally alter the discourses employed within, and disseminated through, these institutions, in a manner that would lead to the problematization, rather than the endorsement, of the ecologically deleterious technological, political and economic trajectories of our time.

  • Description: The primary objective of this treatise is to develop a framework that small businesses can use to implement IT governance. This framework for IT 6 Governance in Small Businesses, called ITGovSB, will be based primarily on the CobiT framework and the ISO/IEC 27002 information security controls. In order to achieve the primary objective, it is necessary to understand the differences between IT governance in small businesses and larger organisations. Consequently, one of the secondary objectives of the paper is to derive characteristics that define IT governance in small businesses. Another secondary objective is to implement the ITGovSB framework at a small business to evaluate its effectiveness.

  • Description: Most current Network Intrusion Detection Systems (NIDS) perform de-tection by matching traffic to a set of known signatures. These systems have well defined mechanisms for the rapid creation and deployment of new signatures. However, despite their support for anomaly detection, this is usually limited and often requires a full recompilation of the sys-tem to deploy new algorithms.

  • Description: South African Higher Education has gone through various changes and challenges, one of these being the merger process. Various Universities and Technikons were forced to merge in an effort to aid the transformation and restructuring of the Higher Education landscape in the post-apartheid era. From an ICT point of view, the merged Institutions ended up with massive and distributed computing facilities. These facilities must be managed and secured and it can be appreciated that the complexity and magnitude of this task is compounded by the large and varied user population (i.e. students) using the facilities. With the exploding use of mobile consumer devices (such as cell phones, personal digital assistants, MP3 players, portable storage devices such as flash drives, etc), Higher Education Institutions are faced with the even more complex task of managing and securing the computing infrastructure, while large numbers of students can enter computer labs and use these devices at random. In some circles, portable devices are touted to be the next panacea in higher education. This, together with the popularity these devices enjoy under the student body, makes it a fait accompli that mobile consumer devices are “here to stay”. Therefore, banning these devices from campus computer labs, is not viable. Universities have to find ways to address security issues through the implementation of appropriate protective measures. This research focuses on finding a solution to mitigating the risks imposed on Higher Education Institutions in South Africa caused by the use of portable storage devices. The research proposes a framework which serves as an outline for the countermeasures that Universities must implement to mitigate the risks inherent to the use of portable storage devices. The scope of the research is limited to flash drives, smart phones and MP3 players.

  • Description: The importance of information in business today has made the need to properly secure this asset evident. Information security has become a responsibility for all managers of an organization. To better support more efficient management of information security, timely information security management information should be made available to all managers. Smaller organizations face special challenges with regard to information security management and reporting due to limited resources (Ross, 2008). This dissertation discusses a Framework for Information Security Management Information (FISMI) that aims to improve the visibility and contribute to better management of information security throughout an organization by enabling the provision of summarized, comprehensive information security management information to all managers in an affordable manner.

  • Description: The coastal zone accommodates some of the most diverse ecosystems in the world and offers a wide range of ecosystem goods and services; consequently it has become a focal point of human development. People are attracted to the coast because of access to resources, favourable climate, aesthetic appeal and potential for recreational activities. As pressure for utilisation and development increases, so does the need to manage the coastal system more effectively. This research focuses on the coastal zone of the Ndlambe and Ngqushwa local municipalities in the Eastern Cape, South Africa, which are physically and environmentally similar, yet have distinct demographic and socio-economic differences. The research integrates information using GIS, from three time epochs, to determine where development and land use change is occurring. The Ndlambe Local Municipality displays high levels of formal development, while the Ngqushwa Local Municipality exhibits little formal development. These differences in development and land use are related to economic, social and legislative ‘drivers’ based on an adapted Driver-Pressure-State- Impact-Response model. The model identifies that development and land use changes lead to increased pressure on the natural system, which in turn leads to shifts in the natural state of the coastal zone, resulting in adverse impacts on the coastal zone. Changes in the natural functioning of the coastal zone highlight the need for a response in terms of changes in legislation governing coastal management and spatial planning. This research concludes that pressure for development in the coastal zone within the research site is beginning to increase and will adversely affect the coastal zone if not managed effectively. These two local municipalities have the opportunity to move forward and develop in such a way that allows for conservation and sound management of the coastal zone, which will ensure long-term sustainability within the coastal zones of the Ndlambe and Ngqushwa local municipalities

  • Description: The control of modern audio studios is complex. Audio mixing desks have grown to the point where they contain thousands of parameters. The control surfaces of these devices do not reflect the routing and signal processing capabilities that the devices are capable of. Software audio mixing desk editors have been developed that allow for the remote control of these devices, but their graphical user interfaces retain the complexities of the audio mixing desk that they represent. In this thesis, we propose a grid approach to audio mixing. The developed grid audio mixing desk editor represents an audio mixing desk as a series of graphical routing matrices. These routing matrices expose the various signal processing points and signal flows that exist within an audio mixing desk. The routing matrices allow for audio signals to be routed within the device, and allow for the device’s parameters to be adjusted by selecting the appropriate signal processing points. With the use of the programming interfaces that are defined as part of the Studio Connections – Total Recall SDK, the audio mixing desk editor was integrated with compatible DAW applications to provide persistence of audio mixing desk parameter states. Many audio studios currently use digital networks to connect audio devices together. Audio and control signals are patched between devices through the use of software patchbays that run on computers. We propose a double grid-based FireWire patchbay aimed to simplify the patching of signals between audio devices on a FireWire network. The FireWire patchbay was implemented in such a way such that it can host software device editors that are Studio Connections compatible. This has allowed software device editors to be associated with the devices that are represented on the FireWire patchbay, thus allowing for studio wide control from a single application. The double grid-based patchbay was implemented such that it can be hosted by compatible DAW applications. Through this, the double grid-based patchbay application is able to provide the DAW application with the state of the parameters of the devices in a studio, as well as the connections between them. The DAW application may save this state data to its native song files. This state data may be passed back to the double grid-based patchbay when the song file is reloaded at a later stage. This state data may then be used by the patchbay to restore the parameters of the patchbay and its device editors to a previous state. This restored state may then be transferred to the hardware devices being represented by the patchbay.

  • Description: The notion of a global knowledge society is somewhat of a misnomer due to the fact that large portions of the global community are not participants in this global knowledge society which is driven, shaped by and socio-technically biased towards a small fraction of the global population. Information and Communication Technology (ICT) is culture-sensitive and this is a dynamic that is largely ignored in the majority of ICT for Development (ICT4D) interventions, leading to the technological determinism flaw and ultimately a failure of the undertaken projects. The deployment of ICT solutions, in particular in the context of ICT4D, must be informed by the cultural and socio-technical profile of the deployment environments and solutions themselves must be developed with a focus towards context-sensitivity and ethnocentricity. In this thesis, we investigate the viability of a software architectural framework for the development of ICT solutions that are context-sensitive and ethnocentric1, and so aligned with the cultural and social dynamics within the environment of deployment. The conceptual framework, named PIASK, defines five tiers (presentation, interaction, access, social networking, and knowledge base) which allow for: behavioural completeness of the layer components; a modular and functionally decoupled architecture; and the flexibility to situate and contextualize the developed applications along the dimensions of the User Interface (UI), interaction modalities, usage metaphors, underlying Indigenous Knowledge (IK), and access protocols. We have developed a proof-of-concept service platform, called KnowNet, based on the PIASK architecture. KnowNet is built around the knowledge base layer, which consists of domain ontologies that encapsulate the knowledge in the platform, with an intrinsic flexibility to access secondary knowledge repositories. The domain ontologies constructed (as examples) are for the provisioning of eServices to support societal activities (e.g. commerce, health, agriculture, medicine) within a rural and marginalized area of Dwesa, in the Eastern Cape province of South Africa. The social networking layer allows for situating the platform within the local social systems. Heterogeneity of user profiles and multiplicity of end-user devices are handled through the access and the presentation components, and the service logic is implemented by the interaction components. This services platform validates the PIASK architecture for end-to-end provisioning of multi-modal, heterogeneous, ontology-based services. The development of KnowNet was informed on one hand by the latest trends within service architectures, semantic web technologies and social applications, and on the other hand by the context consideration based on the profile (IK systems dynamics, infrastructure, usability requirements) of the Dwesa community. The realization of the service platform is based on the JADE Multi-Agent System (MAS), and this shows the applicability and adequacy of MAS’s for service deployment in a rural context, at the same time providing key advantages such as platform fault-tolerance, robustness and flexibility. While the context of conceptualization of PIASK and the implementation of KnowNet is that of rurality and of ICT4D, the applicability of the architecture extends to other similarly heterogeneous and context-sensitive domains. KnowNet has been validated for functional and technical adequacy, and we have also undertaken an initial prevalidation for social context sensitivity. We observe that the five tier PIASK architecture provides an adequate framework for developing context-sensitive and ethnocentric software: by functionally separating and making explicit the social networking and access tier components, while still maintaining the traditional separation of presentation, business logic and data components.
