- Description: Pelargonium reniforme is currently divided into two subspecies, P. reniforme subsp. reniforme and P. reniforme subsp. velutinum. The species falls into section Reniformia along with the closely-related P. sidoides. Observations of the section showed some discrepancies in the current taxonomy; mainly floral variation that was not recorded in the descriptions of the subspecies of P. reniforme, particularly the differences in hypanthium lengths. Patterns of variability were analysed using both morphometrics and inter simple sequence repeat (ISSR) data for P. reniforme (both subspecies), and P. sidoides. Results showed no support for the current subspecific division of P. reniforme but also no support for the current status of P. sidoides as a separate species. However, both morphometric and ISSR data show some evidence for the existence of two distinctly separate groups within P. reniforl1le subsp. velutinum as two distinct types have been recognized: those with bright pink flowers with long tubes (up to 70mm), and those with pale pink flowers with shorter tubes (as little as 8mm). These two forms have been found in a single population (Grahamstown), where they occur sympatrically, as well as in monomorphic populations. Analyses of the processes thought to be responsible for the observed patterns were conducted on the Grahamstown population. Observations of pollinators suggest that long-tongued insects (Butterflies, Nemestrinid flies) pollinate the long-tubed flowers and short-tongued insects (Bombyliid flies, long-tongued bees) pollinate short-tubed flowers. However, analysis of selection gradients in the population, indicate no directional selection is occurring for hypanthium lengths. The results of this thesis show that selection is occurring within Pelargonium reniforme, but at this time, selection is not strongly directional and floral differences are maintained, even when floral forms occur sympatrically. It is suggested that a review of the taxonomy be undertaken as well as additional pollination and selection studies to confirm suspected taxonomic groupings and relationships between the floral forms respectively. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Determining what is newsworthy is a daily challenge even to the very people who source news, produce and disseminate it. This study is part an exposition and exploration of the different approaches that media researchers have used to explain and determine the value of news. Like similar research before it, this study more specifically delves into the news selection process of news of one particular newspaper with the goal of investigating why and how news is selected for publication in the front page. News is the 'result of many forces: ranging from source power, journalistic orientation, medium-preference and market model, news values and production routines and processes. The study briefly expounds on the different definitions of news as perceived in terms of the developed and developing world. Just as journalists do not operate in a vacuum, a close examination of the various definitions reveals that news cannot be defined in isolation. Its definition is intrinsically tied to that of news values. Also explored here are debates about news values and their Western rootedness. Here reference is made to literature regarding theories on the social construction of meanings and on the gatekeeping concept.The study is informed by similar research in gatekeeping studies and sociology of news studies. It is important to state at the outset that the study is not concerned with how news is produced but why there is a bias for certain kinds of news. I am interested in explaining why and how the writers and editors at the East African Standard make decisions about what is worthy of being published on the front page of the newspaper. This distinction is necessary because the theories that inform this study transcend news sourcing and production. This study takes cognizance ofthe fact that one cannot separate social processes from the individual and vice versa. For this reason, this study investigates and analyses the biases of individual gatekeepers at the East African Standard as well as their collective biases. In the concluding section, this study calls for an alternative paradigm for journalism and news. The foregoing discussions in the other sections prove that a universal definition of news and what is newsworthy will not suffice and there is need to contexualise it.

- Description: To support current and emerging database applications, Object-Relational Database Management Systems (ORDBMS) provide mechanisms to extend the data storage capabilities and the functionality of the database with application-specific types and methods. Using these mechanisms, the database may contain user-defined data types, large objects (LOBs), external procedures, extensible indexing, query optimisation techniques and other features that are treated in the same way as built-in database features . The many extensibility options provided by the ORDBMS, however, raise several implementation challenges that are not always obvious. This thesis examines a few of the key challenges that arise when extending Oracle database with new functionality. To realise the potential of extensibility in Oracle, the thesis used the problem area of image retrieval as the main test domain. Current research efforts in image retrieval are lagging behind the required retrieval, but are continuously improving. As better retrieval techniques become available, it is important that they are integrated into the available database systems to facilitate improved retrieval. The thesis also reports on the practical experiences gained from integrating an extensible indexing scenario. Sample scenarios are integrated in Oracle9i database using the data cartridge mechanism, which allows Oracle database functionality to be extended with new functional components. The integration demonstrates how additional functionality may be effectively applied to both general and specialised domains in the database. It also reveals alternative design options that allow data cartridge developers, most of who are not database server experts, to extend the database. The thesis is concluded with some of the key observations and options that designers must consider when extending the database with new functionality. The main challenges for developers are the learning curve required to understand the data cartridge framework and the ability to adapt already developed code within the constraints of the data cartridge using the provided extensibility APls. Maximum reusability relies on making good choices for the basic functions, out of which specialised functions can be built. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: The distribution of real-time multimedia streams is seen nowadays as the next step forward for the Internet. One of the most obvious uses of such streams is to support telephony over the Internet, replacing and improving traditional telephony. This thesis investigates the development and deployment of services in two Internet telephony environments, namely CINEMA (Columbia InterNet Extensible Multimedia Architecture) and VOCAL (Vovida Open Communication Application Library), both based on the Session Initiation Protocol (SIP) and open-sourced. A classification of services is proposed, which divides services into two large groups: basic and advanced services. Basic services are services such as making point-to-point calls, registering with the server and making calls via the server. Any other service is considered an advanced service. Advanced services are defined by four categories: Call Related, Interactive, Internetworking and Hybrid. New services were implemented for the Call Related, Interactive and Internetworking categories. First, features involving call blocking, call screening and missed calls were implemented in the two environments in order to investigate Call-related services. Next, a notification feature was implemented in both environments in order to investigate Interactive services. Finally, a translator between MGCP and SIP was developed to investigate an Internetworking service in the VOCAL environment. The practical implementation of the new features just described was used to answer questions about the location of the services, as well as the level of required expertise and the ease or difficulty experienced in creating services in each of the two environments. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: In recent years, much attention has been given to the question of whether content externalism is compatible with an account of self-knowledge maintaining that we have an epistemically privileged access to the content of our propositional mental states. Philosophers who maintain the two are incompatible (incompatibilists) have put forward two majors types of challenge, which I call - following Martin Davies - the Achievement and Consequence Problems, which aim to demonstrate that self-knowledge cannot be reconciled with externalism. These challenges have spawned a great deal of literature, and a diverse range of arguments and positions have emerged in response. In this dissertation, I intend to focus on examples of these different avenues of response, and show how none of them are adequate. In the first chapter, I lay the groundwork for the debate, setting up how externalism and self-knowledge are to be understood, and outlining both the incompatibilist challenges as well as the available responses to them. In the second chapter I examine these responses in more detail, concluding finally that the best available response is Tyler Burge's. Burge has two arguments that together establish his compatibilist position. First, he shows that even if externalism is true, our judgements about our occurrent thoughts are immunejrom error. This establishes that our judgements about our thoughts must be true. Second, he offers a transcendental argument for self-knowledge, arguing that our access to our mental states must be not only true, but non-accidentally true, in a way sufficient for genuine knowledge. This establishes that we possess the correct epistemic entitlement to our thoughts. In the third chapter, I argue Burge's arguments do not, in fact, give us good reason to suppose externalism and self-knowledge to be compatible. This, I argue, is because B urge relies upon a transcendental argument, which, in this context, cannot establish that we have self-knowledge if externalism is true. All it establishes, I argue, is that we do possess self-knowledge. And this is insufficient to establish that externalism and self-knowledge are compatible. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Monetary policy in South African is the primary means by which the authorities can influence activity in the overall economy. The South African Reserve Bank accommodates banks through repo transactions for which they charge the repo rate. The most important market in the transmission of the repo rate to the rest of the economy is the interbank market. As such, a detailed discussion of this market is given. In September 200 I the monetary authorities made certain adjustments to the repo system of accommodation, which included changing the repo rate from a floating rate to a fixed rate that would be administratively determined by the MPC. This was done to address certain weaknesses in the floating rate system. This thesis examines and compares the period before and after the adjustments to the repo system, with the aim of determining whether or not the monetary authorities achieved the goals intended from making this change. The repo rate, prime interbank rate, 3-month NCO rate and the prime lending rate are analysed using the Engle-Granger two variable approach and an ECM model to test for causality. It was found that the monetary authorities did not achieve their intended goals as the relationship between the repo rate and the interbank rate was more significant in the first period. Furthermore, the direction of causality the authorities hoped to achieve by implementing the changes were in fact already in place. As such the adjustments to the system changed the transmission mechanism from the one desired by the authorities to one that was not intended. The conclusions reached by this study show that, in terms of the objectives of the monetary authorities, the previous repo system functioned better. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: The Internet and World Wide Web have become dominant newsgathering tools in a sholi period of time. While the body of research, particularly in the First World, has developed quickly along with the Web, many unanswered questions remain on how journalists in developing countries make use of the Internet for newsgathering purposes. This study combined social constructivist theory with the socio-organisational and cultural approaches to news production in order to critically investigate how journalists at The Post newspaper in Zambia relate to, and make use of, the Internet as a newsgathering resource, in the context of Third World conditions. The study critiqued technological detelminism perspectives on journalists' use of the new information technology. The technological determinism theory, which has largely been advanced by some scholars from the developed world, takes a celebratory approach to journalists' use of the Internet in the newsroom. Using qualitative semi-structured interviews and observations, the study established that while journalists at The Post acknowledged the lnternet's potential in news gathering, factors such as unreliable telecommunications infrastructure, poor Internet skills, lack of local content on the World Wide Web, and organisational and occupational demands inhibited the use of the Internet as a journalistic newsgathering resource. The study established further that online reporting is only a tool within the broader news gathering and production process; and in the case of The Post, it does not replace the traditional news gathering techniques used by journalists, particularly direct contacts with human sources. The respondents cited face-to-face interviews, a traditional means of newsgathering, as the main driving force in news gathering routines at the newspaper. However, although the respondents saw some mixed blessings in the Internet as a reporting tool, they also believed that the benefits outweighed the problems. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: The Internet and World Wide Web have become dominant newsgathering tools in a sholi period of time. While the body of research, particularly in the First World, has developed quickly along with the Web, many unanswered questions remain on how journalists in developing countries make use of the Internet for newsgathering purposes. This study combined social constructivist theory with the socio-organisational and cultural approaches to news production in order to critically investigate how journalists at The Post newspaper in Zambia relate to, and make use of, the Internet as a newsgathering resource, in the context of Third World conditions. The study critiqued technological detelminism perspectives on journalists' use of the new information technology. The technological determinism theory, which has largely been advanced by some scholars from the developed world, takes a celebratory approach to journalists' use of the Internet in the newsroom. Using qualitative semi-structured interviews and observations, the study established that while journalists at The Post acknowledged the lnternet's potential in news gathering, factors such as unreliable telecommunications infrastructure, poor Internet skills, lack of local content on the World Wide Web, and organisational and occupational demands inhibited the use of the Internet as a journalistic newsgathering resource. The study established further that online reporting is only a tool within the broader news gathering and production process; and in the case of The Post, it does not replace the traditional news gathering techniques used by journalists, particularly direct contacts with human sources. The respondents cited face-to-face interviews, a traditional means of newsgathering, as the main driving force in news gathering routines at the newspaper. However, although the respondents saw some mixed blessings in the Internet as a reporting tool, they also believed that the benefits outweighed the problems. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: This study was conducted in South Africa. South Africa is the first country within the Southern African Development Community to have regulated plastic shopping bags waste through the imposition of both a standard on thickness and a levy. Given this scenario, the Plastic Bags Regulations present an illustrative case for researching complexity, uncertainty and controversies surrounding a new trend in environmental policy making, namely waste product regulation. The thesis focuses on understanding and investigating tensions, debates and responses emerging from the policy process as actors and actor-networks put not only the Plastic Bags Regulations asfocal actant (token) but also other actants and actant-networks as well. To this end, a research question that addressed environmental policies, tensions, debates and responses that informed the development of South Africa's Plastic Bags Regulations was spelt out. The research objectives included the need to: (I) analyse selected international environmental policy processes surrounding plastic shopping bags litter and waste regulation and how these influenced developments in South Africa; (2) identify actors, actants and actor/actant-networks that shaped and were being transformed by South Africa's Plastic Bags Regulations and explain the tensions, debates and responses arising in the policy processes; (3) identify environmental policy outputs and assess outcomes emerging from the formulation and implementation of South Africa's Plastic Bags Regulations; and (4) establish patterns in environmental policy process reforms around South Africa's Plastic Bags Regulations. The language of actors (human), actants (non-human) and actor/actant-networks brings to the fore the aspects of processes and relationships that exist around them. As such, insights from the actor/actant-network theory (AANT) were drawn upon to inform the research. AANT enquiry framework collapses binaries such as nature/society, art/science, structure/agency and global/local historically associated with a particular type of social theory. AANT also denies that purely technical, scientific or social relations are possible (the notion of quaSi-objects or token). Data sets were generated following' the Plastic Bags Regulations as token actant with time frames ranging from prior to, during and after the formulation of the regulations. Similarly, data analysis drew insights from AANT's four moments of translation namely problematisation, interessement, enrolment and mobilisation, with the intervention theory providing an evaluative perspective that complemented AANT. The findings were that after the promulgation of the first draft of the Plastic Bags Regulations in May 2000, tensions emerged around the nature of regulation (whether command and control - preferred by government or self regulation - preferred by industry and labour). In this regard the latter group raised concerns about jobs, income and equipment loss as well as the need to have a holistic approach to waste management rather than targeting a single product at a time whilst the former maintained that this would not be so. As such, education, awareness and stringent antilitter penalties were proposed by industry and labour as sustainable responses to the problem of plastic shopping bags waste rather than regulation. These debates continued and resulted in minor amendments to the original regulations as finalised by Government in May 2002. However, industry and labour continued lobbying government resulting in the conclusion of the Plastic Bags Agreement in September 2002 and the ultimate repulsion of the May 2002 regulations in May 2003. As revealed by this research, these responses led to broader social responses and further tensions as demand for plastic shopping bags went down by about 80% although an estimated 1000 jobs were lost and a number of companies lost equipment and business (with some closing down) following the implementation of the regulations. During implementation, debates emerged around the need to promote locally made carry facilities with two alternatives in sight namely: the Green Bag and the Biodegradable Plastic Bag. Debates also took place regarding enforcement of the new law resulting in the amendments of various pieces of legislation including the Environmental Conservation Act, Environmental Management Act and the Revenue Laws Act. Overall, a 15-year policy reform cycle and sub-cycles was determined. The research also established that the government considered the regulations a success and was already implementing simi lar initiatives to regulate other waste products, among them, used tyres, used oil and glass, confirming the trend towards waste product regulation in South Africa. From these research findings, a series of conceptual frameworks were drawn up to clarify the nature of tensions, debates and responses surrounding certain lead actors, actants and actorlactant-networks. Some of the conceptual frameworks that emerged around the actors and actor-networks include Organised Government, Organised Industry and Organised Labour. Conceptual frameworks that emerged around key actants and actant-networks include the Integrated Pollution and Waste Management, Plastic Bags Regulations as well as the discourses surrounding the Green bag and biodegradable plastic bags. The thesis concludes by reflecting on how the above and the grand actor/actant-network conceptual frameworks emerging from this research might be adopted with varying degrees of flexibility to research environmental and waste management policy processes in different waste product regulation set-ups. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: The purpose of this research was to investigate the clinical phenomenon of destructive narcissism. Contemporary Kleinian and neo-Kleinian theoretical perspectives provided the interpretative perspective on the complexities of inaccessible personalities and subtle forms of internal destructiveness. Four research questions were formulated to interrogate the individual and collective experiences of three male patients whose internal worlds seem to be governed by rigid intrapychic structures organized around the dictatorship of a constellation of seemingly impenetrable defensive strategies. These questions were as follows: 1. What emotional states, actions and experiences of self and others characterize the clinical phenomenon designed as destructive narcissism and distinguish it from other forms of character pathology? 2. What early developmental experiences and relationships may have pre-disposed individuals to the development of this type of character pathology? 3. How are the psychodynamic processes of destructive narcissism structured and configured in the psychotherapeutic process and progress? 4. What are the transference/countertransference psychotherapeutic manifestations of the psychodynamics of destructive narcissism? The illustrative-didactic case study method was utilized to discuss pertinent aspects of each patient. This included their early developmental histories, inter- and intrapersonal relationships, their current mental state, defensive strategies and their stated reasons for commencing psychotherapy. In addition, the structure of the psychotherapeutic process with these patients was reviewed in depth. Various psychic and personality features, as unveiled through this process were discussed, as well as the implications of these for the therapeutic endeavor. The features chosen for discussion were: Firstly, the constellation of the internal object world, the capacity for symbolic thought and defensive organizations. Secondly, therapeutic ambivalence, which made psychotherapy untenable, was explored in conjunction with transference/countertransference issues. Thirdly, the shadow sides of psychotherapeutic change with these patients were considered and the issues of therapeutic failure and other treatment possibilities were examined. It was concluded that there need be an important shift with regard to the psychotherapeutic goals for those patients whose condition may be chronic, and for whom it appears that psychotherapy is of little benefit. In essence, the intent of psychotherapy with these patients is to reach the healthy sane patient of the patient within the pathological organization. Attempts to unravel the perverse gratification and protection derived from the domination of the narcissistic structure may not be enough, and the patient's collusion with the internal destructive gang should also be exposed. If this can be achieved, the patient may come to accept the existence of a part of himself as truly destructive. This, in turn, cannot be disowned, therefore the patient has to live with it. Thus, in destructive narcissism, the challenge for the therapist is the extremely difficult task of disentangling the patient's pain from the idealization of internal destructiveness. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: In the present organisational climate characterised by intense competition, the success of an organisation is increasingly dependent on its employees' expertise and knowledge (Carrel, Elbert, Hatfield, Grobler, Marx & Van der Schyf, 1997). Employees need to be motivated to contribute to the organisation's goals, for their knowledge and expertise to benefit an organisation (Lawler III, 1994). Organisations need to foster a situation in which employees have a positive attitude towards work and are able to benefit personally through directing their effort towards organisational goals. (Robbins, 2000) This study focuses on an organisation that has managed to link job satisfaction with organisational gain, and explores the link between these two subjects. A case study of a South African mining operation is reported on, and examined in-depth. The mine, a successful operation in terms of productivity, is recognised by its holding company as exemplary and is competing with the best base metal producers in the world. The research was conducted in two stages. The first stage consisted of 20 semi-structured individual interviews. Ten employees were selected from both the lower employee-levels and the higher employee-levels. The individual interviews focused on the experience of working at the mine with particular reference to interpersonal dynamics, job satisfaction, leadership style, and reward systems. During the second stage of the research, focus groups were conducted with two groups of seven employees each, one group from the lower-levels and one from the higher-levels. The focus groups aimed at obtaining a deeper understanding of the issues that emerged from the individual interviews. Grounded theory analysis was used during both the first, and second phase of the study. The results indicated that the mine's employees experience a high level fulfilment of higher-order needs, and that this experience is a reaction to the mine's performance enhancing culture. It is further shown that the same factors that create job satisfaction, when applied in excess, or in certain circumstances may lead to dissatisfaction within the same context.

- Description: This thesis reports on a critical, ethnographic investigation into the reading practices of a group of 14 foundation year students at Rhodes University in 2002. The university had identified all the student-participants as 'underprepared' for university learning: they were from poor, socio-economic backgrounds, used English as an additional language, and had been educated in township or rural schools. Using the Socio-cultural model of literacy (Heath, 1984; Gee, 1990 & Street, 1993), the study explores the culturally-shaped attitudes and assumptions about reading that the students brought with them into a tertiary learning context from their homes, communities and schools. It reports on their subsequent efforts to become academic readers in the disciplinary context of History. Framing Theory (Reid and MacLachlan, 1994) was employed to analyse the kinds of matches and mismatches that arose between the students' frames about the nature and purpose of reading, and those implicitly accepted as normative by teachers in the History department. It accounts for the students' difficulties in achieving epistemological access in terms of a conflict of frames: both the students and their teachers usually failed to recognise each others' constructions about the nature and purpose of 'reading for a degree'. The study'S critical purpose required that its potential for generating emancipatory consequences needed to be investigated. Thus the study reports on how both sets of participants began to reframe their understanding of academic reading, by describing the ways in which they reflected on the findings in the final stages of the research process. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Wetlands are an important part of the landscape as hydrogeomorphological ecosystems. Over the centuries their importance has not received relevant attention; instead they have been treated as wastelands impeding development for maximum economic benefits. Research evidence from different parts of the world has influenced the change of such negative perceptions to an extent that the issue of wetlands' rehabilitation/restoration, conservation and management is firmly on the global agenda and local agendas of various countries, as evidenced by the adoption of the Ramsar Convention in 1971, and the Working for Water and Working for Wetlands programmes of the South African government. The aim of this research was to investigate the hydrological and geomorphological functions of a headwater wetland located in the Featherstone Kloof Catchment near Grahamstown, South Africa. The research was based on the hypotheses that wetlands store sediments, attenuate floods, store water and prolong downstream flows. A literature survey was conducted to gauge the state of knowledge about wetlands, particularly their hydrogeomorphology. An attempt was made to locate the study area within the broad historical and spatial context using a number of methods, including the radiocarbon dating of wetland sediments, the review of relevant literature and the analysis of historical hydroclimatic data. The results revealed that the wetland has existed for approximately 2000 years - as the oldest radiocarbon date obtained was 1850±50 BP. An analysis of more than a century (+120 years) long Grahamstown rainfall series indicated a steady fluctuation of rainfall around the mean, with regular decada1 cycles of wet and dry spells. Years with more rain below average were more common than those with higher rainfall, and storms events were quite common in the III area over the period. The distribution of seasons in the area over a calendar year period was demonstrated through the use of evaporation data. An intensive monitoring of hydrological and geomorphological variables was carried out using a combination of methods. The topography of the instrumented site was determined using a Total Station from reference benchmarks. Hydrological measurements included a nest of forty-eight piezometers for water table monitoring, and streamflow gauges at the upstream and downstream limits of the study site. Soil stratigraphic analysis was carried out through field techniques and laboratory measurements. A survey of wetland sediments was carried out after the main floods events. Data generated were used to analyse relationships between various variables and their role on the functioning of the wetland. The water balance of the wetland was quantified. The results indicated that the wetland was able to perform the cited hydrogeomorphological functions to some extent. For example, one of the key findings of this research is that the wetland was important in sustaining base flows under normal circumstances. However, the wetland did little to attenuate large floods. The results also revealed some important questions that require further research, including the role played by extreme flood events in altering wetland characteristics, the contribution of each water balance component in the hydrological functioning of wetlands, and importance of quantifying sediment budgets of headwater wetlands. The study demonstrated the complex nature of the wetland hydro geomorphology and that certain questions about wetlands require direct field monitoring to be better understood. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in
