- Description: The development of small (<300 km²), private game reserves has become a trend, not only in the Eastern Cape Province, but also elsewhere in South Africa as a result of a shift in land use practise from agriculture to ecotourism. The resultant re-introduction of elephants to many of these reserves has lead to management concerns because of the limited research on small reserves regarding their impact on the vegetation. In this study I assessed the space use, habitat selection, diet and impact of two elephant populations on the vegetation in the Eastern Cape Province between February 2004 and March 2005. Home range sizes were calculated using the kernel utilization distribution method. Home range sizes for elephants on Kwandwe were significantly larger during summer than winter (p<0.05). There was no significant difference between the home range sizes of the herds and males within a season and during summer the elephants utilized about 75 % of the reserve and only 54 % during winter. On Shamwari, the herd utilized about 92 % of the reserve during summer and 83 % during winter; while the males utilized 76 % of the reserve. Core areas for both elephant populations shrank from summer to winter and were concentrated around the permanent water sources on each reserve. Habitat selection was assessed using χ² tests and Bonferroni confidence intervals. On Kwandwe, there was a significant difference between observed and expected use of vegetation types (p<0.05) and karroid shrubland was strongly avoided by both herds during summer and winter. The preferred vegetation types of the males ranged from relatively open (short euphorbia thicket, bushclump karroid thicket and karroid shrubland) to completely open (old lands). On Shamwari, subtropical thicket, bontveld and montane grassland were avoided; while primary and secondary acacia thicket, riverine thicket and cultivated lands were preferred. The predominant vegetation type in the home ranges of herds on Kwandwe and Shamwari was subtropical thicket. The diet was assessed by direct observations over two seasons and dietary preferences were calculated. There was a significant difference in the frequency of occurrence of plants in the diet on the two reserves (p<0.05) and no significant effect of time of day or season (p>0.05). Seventeen woody plant species were utilized on Kwandwe and 23 species were utilized on Shamwari. Grass constituted a significantly greater percentage of the diet in summer than winter (p<0.05). Elephants on Kwandwe showed a selective preference for Ozoroa mucronata, Pappea capensis and Acacia karroo; while on Shamwari, A. karroo was selected. Transects were conducted in two different vegetation types on each reserve so as to assess the impact of elephant on the vegetation and damage scores were then calculated from these data. There was no significant effect of vegetation type or elephant density on mean damage scores in Kwandwe (p>0.05). Five hundred and seventy-eight plants were assessed in the subtropical thicket vegetation type and 225 plants were assessed in the savanna-type vegetation, with more than half the trees showing low levels of damage that could not only be attributed to elephants. Mean damage was highest for Portulacaria afra and Pappea capensis in subtropical thicket and for Rhus spp. in the savanna-type vegetation. On Shamwari, 408 plants were assessed in subtropical thicket and 215 in the savanna-type vegetation, with more than 70 % of trees showing low levels of damage. There was a significant effect of plant species and elephant density on the mean damage scores in subtropical thicket, with Aloe ferox showing more damage than the other plant species (p<0.01). In the savanna-type vegetation, A. karroo was the most severely damaged. Overall, damage was greater in the thicket vegetation type compared to the more open vegetation type on both reserves.

- Description: Financial reforms were a major component of structural adjustment programs deemed necessary for developing countries in the mid 1980s. These were not only meant to improve the sector, but would ultimately enhance economic growth and help in poverty alleviation. At the top of these reforms was financial liberalisation. Kenya, like many other sub-Saharan African countries, undertook financial liberalisation in 1991, one of the measures was decontrolling interest rates. With market driven interest rates in place it was assumed that there would be increased efficiency in bank lending, as well as growth in credit availability as deposits increased. A key indicator of this improved intermediation process would be a narrowing interest rates spread, that is, the margin between the deposit and lending rate. Paradoxically, however, the expected benefits of these reforms did not accrue to Kenya's banking sector. This study focuses on financial reforms and the spread of interest rates in Kenya's banking sector. Using a trend analysis, spanning the period before and after liberalisation, interest rates spread are shown to have escalated dramatically upwards after liberalisation. An analysis of three macroeconomic variables, namely, the exchange rate, inflation rate and economic growth offer little, or inconclusive evidence, that they were the main causes of the wide interest rate spread. In fact, the spread is closely linked to institutional/structural factors such as non-competitiveness in the banking sector, imprudent lending practices and poor and/or inadequate banking supervision. Policies for improving the institutional infrastructure and thus moderating the spreads are highlighted.

Foucault, historicism and political philosophy

- Description: This thesis defends an ontological and epistemological account of Michel Foucault's post-structuralist philosophy, to argue that political philosophy needs to take into account the historical and political contingency of subjectivity and discourse. I show that by addressing the historical and political contingency of knowledge, Foucault's work overcomes the flaw of foundational epistemology in political philosophy, which treats true discourse as universal and disinterested. In doing so I hope to have to refuted the mainly positivistic and humanist schools of thought that lay claim to universal and foundationalist notions, by demonstrating the extent to which their misgivings about Foucault's work are informed by and founded upon an unjustified a-historicism. The thesis is composed of three chapters, the first of which deals with an ontology of the subject, the second, with an ontology of social relations, and the last with epistemology. In each chapter I use dialectical analysis to reveal how interests necessarily mediate subjectivity, social relations, and knowledge. The first two chapters defend Foucault's conception of power, by way of an analysis of the relations between Foucault's work and Sartre's existential phenomenology. I show how both Foucault and Sartre successfully address the problem of historicism for political philosophy with their respective conceptions of human freedom. The final chapter defends Foucault's conception of the relations between power and discourse, to show how it overcomes the a-historicism of universal, foundational epistemology. These three chapters demonstrate the importance of accounting for historicism in political philosophy. Claims to universal interest, because knowledge is conditioned by conflicts of interest, often mask political domination. It is important, then, to remember, in political philosophy, that knowledge is evaluative and interested, reflecting historically and politically mediated evaluations. One should be suspicious of ' natural facts' , used to justify actions or beliefs, thereby masking the choices that inform them. I have used the work of Michel Foucault to motivate this claim.

- Description: The North Eastern Cape in South Africa is part of a larger province that is in desperate need of job creation and economic development. In light of these needs, efforts have been made by members of the community and outside investors to generate new forms of income in the area. These economic developments emerged in the form of small-scale tourism initiatives and commercial forestry. The impact of these developments on the small community of Maclear differs in nature and is bringing about social change and influencing identity. In this thesis, I explore the effects of each of these developments on the local farming community, particularly the established white English-speaking farmers. For various important reasons, such as the changes to land use patterns occurring around them in terms of forestry and tourism initiatives, I chose to examine the situation of this minority. In general discussions and portrayals of white farmers, it is hypothesized that whites living in small farming communities are resistant to change, politically stagnant and socially conservative. In this thesis I test this hypothesis and investigate what South Africans might see as the core, or whether there is a core of, white settler identity. TIle idea of 'frontiers' being heartlands was emphasized in Maclear as residents spoke about the pioneering efforts of their forefathers and discussed these efforts as the essence of their identity. Forestry is a contemporary ' frontier' encroaching on these white Settlers. A dynamic concept of landscape is central to these identity construction efforts. In this thesis I explore, through different articulations of landscape, how residents, recent arrivals and investors attempt to embed their identity and resources in the community. I ask whether it is possible for members of the white community to produce an alternate and politically viable interpretation of landscape in post-apartheid South Africa. Can land and landscape offer them a sense of belonging and identity? What is their experience in view of the impositions of major investors who see land purely as an economic unit? The research does not explicitly investigate how 'new' black farmers and farming groups perceive and experience land and landscape. What is noted is the imagined passivity of black labourers on white-owned land. This thesis touches on issues inlportant to democratic change and progress in South Africa. How will the new government deal with the thorny issue of land redistribution in the face of competing claims for land and identity? How will the various sections of the white community (in this case the farming community) negotiate their identity in the new South Africa? Also, what do ' frontier' towns like Maclear reveal about the nature of white identity in post-apartheid South Africa? This thesis relies on gender and constructionist theories of landscape as developed by Appadurai (1996) to explain the dynamic nature of landscape in Maclear. It also explores and appraises the idea of ' frontier'. In the analysis of identity, I take into account that white settlers 'success' relies in part on the settlers ability to adapt to the ' frontier' and their ability to construct a new identity in their newfound 'homeland' (simliar to Paul Gilroy's (1993) "double consciousness). Keywords: South Africa, Maclear, Farming, White Identity, Landscape and Tourism.

Diverse discourses are drawn in to consider issues of body, subjectivity and spectatorship, refracted through the writer’s experiences of and discontent with making theatre. Written in a fractal-like structure, rather than a linear progression, this thesis unsettles discourses of truth, thus simultaneously intervening in debates about the epistemologies of the body and of theatre in context of the academy. Chapter 1: Methodological Anxieties Psychoanalytic theory provides a way in for investigating the dynamics of theatrical performance and its corporeal presence, by focusing on desire and its implication in the notions of loss and anxiety. The theories of the unconscious and the gaze have epistemological implications, shifting definitions of “presence” and “truth” in theatre performance and writing about theatre. This chapter tries to outline the rationale for, as well as to enact, an alternative methodology for writing, as an ethical response to loss that does not insist on consensus and truth. Chapter 2: (Refusing to) Look at Trauma This chapter examines the politics that strives to make suffering visible. Discursive binaries of public/private, dead/living, and invisible/visible underlie the politics of AIDS and sexuality. These discourses impact on the reception of Bill T. Jones's choreography, despite his use of modernist artistic processes in search of a bodily presence that aims to collapse the binary of representation (text) and its subject (being). The theory of the gaze shows this politics to be a phallocentric discourse; and narrative analysis traces the metanarrative that results in the commodification of oppositional identities, so that spectators participate in the politics as consumers. An ethical artistic response thus needs to shift its focus to the subjectivity of the spectator. Chapter 3: The Screen and the Viewer’s Blindness By appealing to a transcendent reality, and by constituting spectators as a participative community, ritual theatre claims to enact change. The “truth” of ritual rests not on rational knowledge, but on the performer’s competence to produce a shamanic presence, which director Brett Bailey embraces in his early work. Ritual presence operates by identification and belonging to a father/god as the source of meaning; but it represses the loss of this originary wholeness. Spectators of ritual theatre are drawn into an enactment of communion/community, the centre of which is, however, loss/emptiness. The claim of enacting change becomes problematic for its absence of truth. Bailey attempts to perform a hybrid, postcolonial aesthetics; but the problem rests in the larger context of performing the notion of “South Africa”, a communal identity hardened around the metanarrative of suffering, abjecting those that do not belong to the land of the father/god – foreigners that unsettle the meaning of South African identity. Conclusion: Bodies of Discontent The South African stage is circumscribed by political and economic discourses; the problematization of national identity is also a problematization of image-identification in the theatre. In search for a way to unsettle these interrogative discourses, two moments of performing foreignness are examined, one fictional, one theatrical. These moments enact a parallel to the feminine hysteric, who disturbs the phallocentric truth of the psychoanalyst through body performance. These moments of disturbing spectatorship are reflected in the works of performance artist Marina Abramovic. Her explorations into passive-aggression, shamanism and finally theatricality and the morality of spectatorship allow for an overview of the issues raised in this thesis regarding body, viewing, and subjecthood. Sensitivity to the body and its discontent on the part of the viewer becomes crucial to ethical performance.

- Description: This thesis aims to provide a better understanding of the ways in which the Internet supports the consumer decision process of potential customers in an online car retail environment. The thesis is mainly focused on how this can be done in South Africa. A case study approach was adopted in investigating the case of McCarthy Call-a-Car. Interviews were carried out with McCarthy Call-a-Car employees and documents and the Call-a-Car website, were analysed. It was revealed that Call-a-Car focuses on using the Internet to support customers in the pre-purchase phase only. The purchase and post-purchase phases are carried out offline at its dealership network and Club McCarthy respectively. The findings showed that Call-a-Car views the Internet as a marketing tool that provides convenience to customers searching for product information in the pre-purchase phase. The interviews revealed that due to Call-a-Car's strategy, as well as practical problems of selling online, the customer will still have to visit a dealership to conclude a purchase and for post-purchase support. From this research it appears that there are three main issues arising out of Call-a-Car's usage of the Internet in the customer buying process: firstly, the research revealed that instead of cutting out the middle-man, the Internet has created new types of intermediaries called "cybermediaries" and that Call-a-Car is one such intermediary. Secondly, it was revealed that trust is crucial in the online environment and that Call-a-Car builds trust through branding. Thirdly, the Internet has not affected prices online, despite theoretical estimations that the Internet would induce lower prices. The main recommendations for future research are empirical studies to investigate if the cybermediary model is unique to the car industry and whether this business model could be applied to other look and feel industries such as real estate. Future studies could also investigate the mechanics of trust-building and brand-building in the online environment and finally, studies from the customer perspective considering what Internet tools the customer would like to see online to support them during their buying decision process.

- Description: September 11, 2001 presented the world with events that challenged its conception of reality and called into question current ideologies. In order to make sense of the attacks, people turned to the media for information and interpretation. My interest lies in the media’s role in shaping ideologies as a result of the events of September 11, 2001. I focus on the newspaper editorial because it, in particular, functions not only to report the news but also to interpret the news for the reader. My analysis is centred on the first reaction to the events in five ‘core’ editorials drawn, respectively, from an American, British, South African, Zimbabwean and Kenyan newspaper. The specific focus, in each case, is the representation and evaluation of social actors, the events themselves and the schematic structure of the editorial. I adopt a critical perspective through the use of Critical Discourse Analysis, supported by Systemic Functional Grammar and APPRAISAL. This perspective involves three inter-connected stages of analysis: a Description of the formal discourse properties of each editorial; an Interpretation of the prevailing situational context; and an Explanation of the sociohistorical context in each case. Language, being a form of social practice, is a means by which power relations in society are reproduced or contested (Janks 1997). By analysing the editorials’ discourse I identify whose interests are being served and how each text positions a reader’s attitudes and opinions. My analysis reveals the fact that the editorials distinguish between “us” and “them” groups for the purposes of advancing and confirming in-group ideologies and agendas. This is achieved in each case through comparing the paper’s ideology with the opposing ideology, which is presented as deviant and unsupportive of the in-group. My analysis of the African editorials, in particular, further reveals the exploitation of this division for the purposes of promoting and interpreting local political and social issues. Examination of the processes and conditions surrounding the production of the editorials shows how they are significantly influenced and constrained by the ideologies of both the writer and newspaper owner as well as by the situational context within which they were written. My analysis of the schematic structure of the editorials, in line with Bolivar (1994), reveals consistent use of three-part structures by which editorial opinions are evaluated. In concluding I provide suggestions, based on my research, for how critical language awareness can inform media education at high school level in South Africa. I argue that students should be equipped with tools, such as those I employed, to critically analyse and uncover how language is used to promote ideologies in the editorial of newspapers.

- Description: ‘What is required is the ‘politics of the rhizome’ in which everyone, every community, every nation and every major region comes to terms with the uniqueness of their situation and acts accordingly – and realises that it is only by vast numbers of people, of groups and organizations acting in accordance with possibilities of their situations, that the environmental crisis will be solved.’ (Gare, 1995:161). The study investigates the implementation of Local Agenda 21’s education, awareness and training component by the Gaborone City Council Environmental Health Department (GCCEHD) to address environmental challenges facing the city of Gaborone, the capital city of Botswana. The research was conducted as a qualitative case study that made use of semi-structured interviews, focus group interviews and document analysis as instruments of data generation. Samples of respondents were selected from the Gaborone City Council (GCCEHD) employees in management positions, workers, and elected political councillors. The study is contextualised through establishing environmental issues in the Gaborone City Council, identifying strategies to address environmental issues and the review of the Waste Management Plan 2003-2009, which the department uses as a guiding document for waste management. The study establishes that the council employees are mostly concerned with issues of waste management and need commitment from all Local Government sectors of the work force. The study established the importance of education, awareness and training as a response to environmental issues facing Gaborone. The study also establishes the need for social education in terms of public education, awareness and training needed for the public to adequately respond to environmental challenges in their context. Models and relevant policy and guiding documents such as the Vision for Greater Gaborone, DPSEEA Model and Botswana Environmental Planning Principles were identified and recommended for the department to consider. The awareness and training activities should be developed and involve the community in environmental management. This should enable the council to create opportunities for income generation, at the same time changing community negative attitudes towards the environment and improving service delivery by the department.

Implementing performance management at local government level in South Africa : a case study on the impact of organisational culture

- Description: Local Government in South Africa has undergone much transformation since 2000. Although much of the change has been to correct imbalances, inequities and disparities within our local communities as a result of Apartheid, change has also been motivated by National Government’s realisation that, as with governments throughout the world, there is a need to modernise all spheres of Government. Part of this transformation process at a local government level in South Africa has been to ensure that municipalities become more responsive to the communities’ needs. The guiding principles for this transformation are contained in the White Paper on the Transformation of the Public Service (1995) and the Batho Pele White Paper (1997). This has informed the Municipal Systems Act: Act 32 of 2000 of which Chapter 6 determines that municipalities will have a performance management system to promote a culture of performance management amongst the political structures, political office bearers, councillors and administration. The performance management system must ensure that the municipality administers its affairs in an economical, effective, efficient and accountable manner. A literature review contained in this research, indicates that internationally, implementing performance management systems at a local government level is impact upon by a number of factors such as the organizational culture of an institution. This research, which has been grounded within a constructivist paradigm, describes the impact organizational culture has had on the implementation process of the performance management system at Buffalo City Municipality. Interviews were conducted amongst the Section 57 employees (i.e. the Directors) and those employees directly responsible for implementing performance management. The four Directors, two General Managers and the portfolio councilor were interviewed. Semi-structured interviews were conducted with the interviewees and this culminated in a total of 10 hours of interviewing. The protocols were analyzed using the guidelines suggested by Boyatzis (1998) and the findings are detailed in two chapters. The findings of the research were that the implementation of the performance management system at Buffalo City Municipality has been impacted on by the dichotomy between the political and administrative leadership, resulting in non-implementation of council resolutions, the lack of an organizational strategy, poor institutional arrangements and inadequate resource allocation, are reported. However, the most important finding was the impact that a culture of fear has had on the implementation process. This culture of fear and its impact on the implementation of performance management system is described as the most pervasive and insidious of all the findings to have negatively impacted on the implementation process. This research ends with recommendations for further research and it is argued that each organization has its own unique organizational culture. The conclusion is that no single typology, as contained in the literature, which can account for the specific impact organizational culture will have on the implementation process of a performance management system at local government level in South Africa. Consequently, implementers of performance management systems must assess the unique characteristics of each organization’s culture prior to implementation, in order to evaluate its impact that the organizational culture can have on the process.

- Description: The practice of inquiry, in which we seek and pursue true beliefs by forming justified beliefs, is important to us. This thesis will address two questions concerning the significance of this practice. These are the question of what explains our preference for this particular belief-forming practice, and whether this value can be explained by the value of true belief alone. To answer these questions I will examme a variety of our intuitive commitments to particular values, assuming their general accuracy. I will use an inference from the goal of a practice to the value of a practice, an inference based on the assumption that when we pursue something it is valuable. I will discuss our intuitive commitments to the value of justification. I will also rely on the implications of the presence of pride and admiration in relation to the outcome of an inquiry (especially in situations where a belief is difficult to form). By using this methodology, I will argue for three sources of value that explain the unique significance of the value of inquiry. The first is the value of its unique role in our being able to form reliably true beliefs. Second, I will argue for Wayne D. Riggs' account of epistemic credit; Riggs defends the value of our being responsible for true beliefs, they are our achievements. Third, I will argue for an additional the value of delivering a skilful epistemic performance, another kind of achievement. I will show that although the value of true belief plays a role in explaining some of the values, the third value for inquiry is independent of the value of true belief. This means that there are intellectual rewards, which can be gained from this practice, that extend beyond the value of true belief. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

The researchers examined the nature of the schizophrenic experience from within the framework of the dialogical model of self, and presented schizophrenic intersubjectivity as a potentially horrifying and disintegrating experience. Lysaker et al (2005) discuss the notion that the individual self unfolds as a composite structure of multiple selves, existing in dialogical interaction with one another. Their research aimed to show that the individual with schizophrenia experiences difficulty tolerating this dialogue on an intrapsychic level. Because interpersonal exchange requires that individuals adopt a variety of self-other modes of relatedness, suggest Lysaker et al, interpersonal engagement for the person with schizophrenia is disclosed as profoundly threatening (ibid.) Moving from the above-mentioned research, this project aims through a hermeneutic phenomenological process to clarify and narrate the subtleties of the intersubjective experience, as that experience is disclosed in the lived world of a person with schizophrenia. How does such an individual experience self in relation to other? How does such an individual negotiate their sense of self in terms of their dialogicality? The phenomenological hermeneutic method, as shaped by such theorists as Gadamer (1976), Heidegger (1962) and Buber (1970), will emerge as the interpretive platform upon which these questions are approached.

Investigating a rural community's use of communication technology: a study of Nakaseke Community Multi-media centre in Uganda

- Description: An assumption that Information and Communication Technologies (ICTs) and economic development have an automatic linkage has gained wide acceptance over the last decade. As a result, developing countries are under pressure to apply this prescription as a solution to poverty. With the help of development partners in the developed world and the United Nations, developing countries have embraced this call to increase access to ICTs to bridge the ever-widening gap between the ‘information rich’ and ‘information poor’ (Castells, 2001). One of the strategies has been the establishment of telecentres where the least privileged people might access ICTs for their own development needs. However, this strategy has tended to overlook contextual factors and circumstances in developing countries. ICTs are thus being introduced in an environment of mass poverty, illiteracy and poor infrastructure, exacerbating existing inequalities in some cases. Much attention has been focussed on initiatives aimed at expanding the ICT infrastructure for wider population access without addressing what the users actually do with such access. This study aims to make a contribution in that direction. The study focuses on Nakaseke Community Multi-media Centre(CMC), the first telecentre introduced in Uganda in 1997. Using a combination of quantitative and qualitative research techniques, the study sets out to develop deeper insights into how the Nakaseke community uses, engages with and relates with communication technologies installed at the telecentre. It probes whether these practices advance the dominant view that ICTs are a panacea for rural development. The findings indicate that while access to communication technology has expanded, albeit at a slow pace, the benefits might take very long to have a significant effect as many targeted users do not make use of the facilities because they lack the human skills and financial resources to exploit the technologies. Other problems such as poor electricity supply and sustainability also actively militate against the potential of the project to deliver. Besides, people tend to appropriate technology in ways different from those intended by its promoters. As Burton (2002) explains through the concept of ‘affordances’ and ‘culture’, some users perceive technologies essentially as something that bestows the status of being modern or sophisticated on their community, rather than as a development tool. In conclusion, it is argued that if used for development, ICTs can indeed make a difference in the lives of rural people. However, besides investing in technology, there is need to invest more in empowering the people themselves with skills, particularly literacy, to enable them use ICTs productively.

Investigating the effects of the proliferation of commercial broadcasting on public service broadcasting: the case of Rivers State of Nigeria Broadcasting Corporation

- Description: 1992 marked a turning point in Nigeria’s broadcasting history as the country formally deregulated her broadcast space. However, it was not until March 2002 that the first commercial radio station was established in Rivers State, a broadcast environment hitherto monopolised by Radio Rivers. The coming of the first independent radio station in Rivers State in March 2002 was followed by the establishment of two other stations in October 2003 and November 2003 respectively. As important as these events in broadcasting in Rivers State are, however, media scholars have argued that in most societies where such change has taken place, public service broadcasters have tampered with their values of being an open space where individuals and groups can come together to be educated, informed, and entertained. This study investigates the extent to which the proliferation of commercial broadcasting outlets has affected Radio Rivers’ public service programming and scheduling. Using a combination of qualitative and quantitative research methods, through in-depth interviews and analysis of the mandate and programme schedules, the study established that while Radio Rivers still maintains some public service values, its current programming policy is driven by the need to compete with the commercial broadcasters. This is evidenced in the decrease in the programme space allocated to current affairs and educational programmes on the schedule, (the genre of public service broadcasting), and the increase in attention to advertisements and entertainment programmes, (the genre of commercial broadcasting). The study also confirms the adverse effects of dwindling financial resources as forcing public service radios to compromise on their public service values, as majority of programmes on Radio Rivers current programme schedules are now geared towards attracting advertisers rather than serving the public good and interests. However, the study proved that it is not in all cases that the entry of commercial broadcasters into Rivers State broadcast space has undermined Radio Rivers public service values. Indeed, in leading to the expansion of interactive, news, and the diversification of entertainment programmes spaces on Radio Rivers’ programming schedules, the proliferation of commercial broadcasters has yielded some positive effects on Radio Rivers public service values and contribution to the public sphere. The study further highlights the need for some policy reforms at Radio Rivers, such as the introduction of licence fees, increased government funding and loosening government’s current control over the station. In addition, there is the need for the edict establishing the station to be amended to reflect the current trends in broadcasting in Rivers State, and above all to reposition Radio Rivers to sustain public good and public interests in its programming.

- Description: The proliferation of PALs (Public Access Locations) is fuelling the development of new standards, protocols, services, and applications for WLANs (Wireless Local Area Networks). PALs are set up at public locations to meet continually changing, multiservice, multi-protocol user requirements. This research investigates the essential infrastructural requirements that will enable further proliferation of PALs, and consequently facilitate ubiquitous computing. Based on these requirements, an extensible architectural framework for PAL management systems that inherently facilitates the provisioning of multiple services and multiple protocols on PALs is derived. The ensuing framework, which is called Xobogel, is based on the microkernel architectural pattern, and the IPDR (Internet Protocol Data Record) specification. Xobogel takes into consideration and supports the implementation of diverse business models for PALs, in respect of distinct environmental factors. It also facilitates next-generation network service usage accounting through a simple, flexible, and extensible XML based usage record. The framework is subsequently validated for service element extensibility and simplicity through the design, implementation, and experimental deployment of SEHS (Small Extensible Hotspot System), a system based on the framework. The robustness and scalability of the framework is observed to be sufficient for SMME deployment, withstanding the stress testing experiments performed on SEHS. The range of service element and charging modules implemented confirm an acceptable level of flexibility and extensibility within the framework.

- Description: Ionospheric phase delays of radio signals from Global Positioning System (GPS) satellites have been used to compute ionospheric Total Electron Content (TEC). An extended Chapman profle model is used to estimate the electron density profles and TEC. The Chapman profle that can be used to predict TEC over the mid-latitudes only applies during day time. To model night time TEC variability, a polynomial function is fitted to the night time peak electron density profles derived from the online International Reference Ionosphere (IRI) 2001. The observed and predicted TEC and its variability have been used to study ionospheric in°uence on Radio Astronomy in South Africa region. Di®erential phase delays of the radio signals from Radio Astronomy sources have been simulated using TEC. Using the simulated phase delays, the azimuth and declination o®sets of the radio sources have been estimated. Results indicate that, pointing errors of the order of miliarcseconds (mas) are likely if the ionospheric phase delays are not corrected for. These delays are not uniform and vary over a broad spectrum of timescales. This implies that fast frequency (referencing) switching, closure phases and fringe ¯tting schemes for ionospheric correction in astrometry are not the best option as they do not capture the real state of the ionosphere especially if the switching time is greater than the ionospheric TEC variability. However, advantage can be taken of the GPS satellite data available at intervals of a second from the GPS receiver network in South Africa to derive parameters which could be used to correct for the ionospheric delays. Furthermore GPS data can also be used to monitor the occurrence of scintillations, (which might corrupt radio signals) especially for the proposed, Square Kilometer Array (SKA) stations closer to the equatorial belt during magnetic storms and sub-storms. A 10 minute snapshot of GPS data recorded with the Hermanus [34:420 S, 19:220 E ] dual frequency receiver on 2003-04-11 did not show the occurrence of scintillations. This time scale is however too short and cannot be representative. Longer time scales; hours, days, seasons are needed to monitor the occurrence of scintillations.

- Description: The research explored the causal relationship between the communal land tenure and the stagnant agricultural productivity in rural villages. It is assumed that there is covariance between the communal land tenure and the stagnant agricultural productivity. The communal land tenure deprived the villagers of the land ownership rights to mortgage their landholdings to secure agricultural credit from financial institutions, or to advance them as own contributions to obtain Government-provided grants under the ILRAD. Under such circumstances, the villagers could not raise the level of agricultural productivity. The Permit to Occupy (PTO) certificates, issued to the landholders, provided for usufruct rights only i.e. right to occupy and use an allotment. The related research was conducted at Nonkcampa village. The metatheory, “Positivism” and the quantitative paradigm were applied to collate and analyse the data. The research findings confirmed the correlation between the land tenure and the agricultural productivity, as the respondents claimed not to have had any access to agricultural inputs. Hence, the agricultural productivity on the arable land had stagnated.
